Commercially Available Testing Tools

Once an application has been developed, the developers must demonstrate that it performs the tasks for which it was designed accurately, reliably and with adequate performance. For this to be fulfilled extensive testing must be carried out and tools have been built to assist with this process. Developers have built different types of tool for addressing different aspects of the same general problem. The importance of proper testing to detect as many errors as feasibly possible has been driven by the increase of malicious or criminal intent on the part of developers that produce applications with functions that facilitate fraud or other criminal activity (an especial risk to the financial industry). This problem has been addressed by European Community Legislation, increasing the onus on software developers to show that they took all reasonable steps to ensure an application was free of defects and suitable for the purpose for which it was developed. Failure to do so could leave the developer liable to be sued by anyone have has incurred a loss in any business as a result of software collapse. The main types of tool that have resulted as a partial result of this are described below. There are a large number of testing tools that are available, but they all work in very different ways. The main types of testing categories are described below. Tools that analyse source code without executing test cases, but in deriving test cases for the software to be tested. There are three different types used in industry that are described below: Code based testing tools accept source code as input and perform a number of analyses that result in the generation of test cases. This type of automated tool can broken down in to four further categories. The first are Code analysers that evaluate test modules automatically for proper syntax; statements are then highlighted where the syntax is wrong, if construction is error prone or if an item is undefined. The second category is Structure checkers where modules are submitted as input and a graph generated, depicting the hierarchy of modules and tools check for structural flaws, for example, determining the location of loops and branches and how they are used within the system. The third type are Data analysers which review data structures, data declarations and module interfaces, and notes improper linkage between modules, conflicting data definitions and illegal data usage. The final type are Sequence checkers where sequences of events are checked and marked if coded in wrong sequence. Specialised testing languages enable a software engineer to write detailed test specifications that describe each test case and the logistics for its execution. An example of one of these languages is Prolog, that is specifically used for test case generation. Requirements based testing tools isolate specific user requirements and suggest test cases (or classes of tests) that will exercise the requirements. Tools that analyse source code during execution of test cases by interacting with a program as it is executing and checking the path coverage, test assertions about the value of specific variables and otherwise instrumenting the execution flow of the program. They can be either intrusive or non-intrusive. An intrusive tool changes the software to be tested by inserting extra instructions or ‘probes† that perform the activities mentioned above. A non-intrusive tool uses a separate hardware processor that runs in parallel with the processor containing the program that is being tested. Systems can be difficult to test because several parallel operations are being carried out concurrently, which is especially true for real-time systems. Therefore it is difficult to anticipate the conditions and generate representative test conditions. However, dynamic test tools can capture a state of events during the execution of a program and so are often called program monitors, because they watch and report the behaviour of the program. The functions of the monitor are to list the number of times a submodule is called or a line of code is executed. These statistics tell testers if the test cases have statement coverage. Another function is to report on whether a decision point has branched in all directions, providing information about branch coverage. System performance information is also provided, including statistics about particular variables e. g. their first value, last value, minimum and maximum values. Breakpoints can be defined for the system, so when a variable attains or exceeds a specific value, the test tool reports the occurrence. Some tools will stop when breakpoints are reached so that the tester can examine the contents of memory or specific data items, as it is possible to change values as the test progresses. Any information captured during the test can be used to provide information about control flow. Another automated tool, analysers, are similar to monitors, except that they can also evaluate captured data to prescribed criteria. A test coverage analyser records the number of each statement executed during a test step and notifies us if certain routines or statements are not executed. A timing analyser works with predefined areas or memory or code and tracks the amount of time spent in each area as system functions are performed. This type of tracking can be useful during performance testing when timing requirements are checked. Tools that simulate functions of hardware or other externals by presenting to a system all characteristics of a system or device without actually having the system/device available. This is particularly useful if another company is developing part of a system; this part can be simulated to allow you to test your own part. The simulator can sometimes be more useful than the device itself as all data regarding the devices' state throughout the test can be stored, aiding in error location. Simulators also help with stress and volume testing, since it can be programmed to load the system with substantial amounts of data, requests or users. Generally, simulators give control over the test conditions, allowing you to perform tests that may otherwise be dangerous or impossible. Test management tools are used to control and co-ordinate testing for each of the major testing steps. Tools in this category manage and co-ordinate regression testing, perform comparisons that ascertain differences between actual and expected output and conduct batch testing of programs with interactive human-computer interfaces. In addition to the functions noted above, many test management tools also serve as generic test drivers. A test driver reads one or more test cases from a testing file, formats the test data to conform to the needs of the software under test, and then invokes the software to be tested. The C/S environment demands specialised testing tools that exercise the graphical user interface and the network communications requirements for client and server. This category can be sub-divided into the following functions: Reverse engineering to specification tools which take source code as input and generate graphical structured analysis and design models, ‘where-used' lists and other design information. Code restructuring and analysis tools that analyse program syntax, generate a control flow graph and automatically generate a structured program. On-line system reengineering tools which are used to modify on-line database systems. Many of the above tools are limited to specific programming languages, although most major languages are addressed and require some degree of interaction with the software engineer. Next generation reverse and forward engineering tools will make much stronger use of artificial intelligence techniques, applying a knowledge base that is application domain specific, i. e. a set of decomposition rules that would apply to all programs in a particular application area. The AI component will assist in system decomposition and reconstruction, but will still require interaction with a software engineer throughout the reengineering cycle. Several testing aids can be combined into one automated tool; a test harness is a monitoring system that tracks test input data, passes it to the program or system being tested and records the resulting output. A test harness can also compare actual with expected output and report any discrepancies. Most test harness tools are environment specific by the nature of the process. Test data set generators can generate test data sets derived from the requirements modelling process. Used in conjunction with test harnesses they will provide a formal documented test environment. In most cases a combination of the above tools will improve chances that a delivered application performs the tasks expected correctly and reliably. All testing tools generate large amounts of information about an applications structure. This information must be interpreted and used to detect and rectify subtle logic and structure error. There is a large amount of interest in producing automated support for this interpretation process; to pinpoint possible problem areas and suggest further lines of investigation. With the exception of Interpreters, that are still in development, the above categories of testing tools are available commercially. There are a large number of products available produced by many different companies, so two case studies have been selected to give an impression of the testing tools commercially available. Where possible, the category of testing tools as described above that each product fits into has been added in brackets after the product name. The current products available from this French company are aimed at user interface testing and there are three product lines. The first, UniTest, is designed to perform unit testing of embedded systems. It can develop test scripts that can run on native, simulator, emulator or target platforms. ATTOL's second product, SystemTest, automates the production and exploitation of integration and validation tests for systems. Both of these two products can be integrated with ATTOL's final product, Coverage (test coverage analyser), which is a code coverage tool that is designed to obtain the level of code coverage during the unit or integration testing. TestStudio is one of four products that make up the software development product, Rational Suite. The TestStudio product is itself made up of other Rational Products. Rational Robot provides thorough testing of an entire application, Rational TestFactory automatically detects run-time errors without user assistance and generates optimal scripts for regression testing. Rational Purify locates hard-to-find run-time errors that cause program crashes. Rational Quantify pinpoints performance ‘bottlenecks' in applications and Rational PureCoverage (test coverage analyser) identifies untested code and provides code-coverage analysis. The nature of many products available is that they perform testing to meet user requirements. To do this they are often a combination of several types of testing tool, which makes it difficult to identify specific categories of testing. However, many of the products available did require the system or application being tested to actually be run, whether on a simulator or real-time, suggesting dynamic testing is used more than static testing. There are however, a huge range of testing tools commercially available, combining many different testing methods.

: Supply Chain Management Is Primarily of Interest to Manufacturing Firms

Overview Supply chains are networks of organisations, information, technologies, activities and resources involved in the movement and conversion of physical goods or services from suppliers to end consumers. These different organisations are interlinked by physical, information and monetary flows. Organisations create value by transforming raw products into finished goods or repositioning of resources thru space and time, which is based on networks of supply chains. Both ways, it involves the movement and conversion of physical goods and information throughout supply chains across the world.Therefore organisations and supply chains are closely interlinked in the creation of value for its customers. Manufacturing firms produce goods for use or sale using labour, machines, technology and other materials usually on a large scale. Processing of materials into products takes place in a factory or manufacturing plant where the organisation’s labour and machines work in unison to tr ansform raw material into a usable product, or using many components and process it into a finished product for the end consumer, just like how a baker is able to transform flour to bread thru labour, skill, machinery and tools.Supply chain management for manufacturing firms To achieve economies of scale, manufacturing firms needs to produce their products on a large scale. Generally the higher the production output of the firm, the lower the unit cost of their product will be. Besides output volume, the speed of production will determine the lead time from manufacture to delivery. High productivity will enable manufacturing firms to achieve shorter production cycles which equates to better competitiveness in their respective markets.Capacity management will determine how efficient the manufacturer will be in producing its goods. Over capacity will result in increased wastage and costs while under capacity will see the firm lose certain profits that it should gain. Thus manufacturer s needs to carefully consider the type and amount of capacity needed for its production when doing its supply chain planning. The timing of capacity changes also needs to be taken into consideration to achieve maximum efficenty given that demands of their products varies with seasonal changes.The ability to react to market demand changes quickly will determine manufacturers flexibility in keeping up with these demands. Manufacturers needs facilities to produce, whether warehouses to store its raw materials or finished goods, or manufacturing plants to produce their products. Services facilities are needed by certain manufacturing industries such as consumer electronics to cater for returns. Distribution centres also determine the efficenty of production distribution and un-nesessary inventory holding will result in higher holding cost.Such facilities require large investments and are integral of the manufacturer’s supply chain strategy and thus proper planning is needed when making these decisions regardong the size, location which affect the overall operations. How manufacturers run their productions also determine how successful will they be in terms of productivity and quality levels. Different types of equipment and processes also affect the cost and output of the manufacturing plant.Information systems that flow both upstream and downstream affects the forecasting, planning, inventory and production levels, they must be robust to ensure the manufacturing firm is able to react accordingly to changing demands and variations. In addition to their internal environment, manufacturing firms needs to consider procurement as an integral part of their supply chain strategy, supplier selection will affect the cost and how the manufacturer will run its production and ultimately affects the whole supply chain. Transportation systems as part of the supply chain plays an equally important role for manufacturing firm’s success.To reduce inventory holding l evels many manufacturing firms are running on a lean basis where they practice Just-In-Time delivery to meet production schedules. Transportation networks to customers have to be equally efficient to reduce lead time in accordance to lean manufacturing. Many manufacturing firms leverage supply chains to achieve competitive advantages in their markets. the case study on Procter & Gamble (Bozarth & Handfield, 2006: Pg 91-92) is a good example of how a manufacturing firm leverages on their supply chain to improve on their effectiveness and lowering cost.Procter & Gamble used to operate under five different business sectors according to different product lines such as paper goods and healthcare products in the mid 1990s. Originally this makes good sense to Procter & Gamble to better manage its’ diverse business. However for the retailers and customers of Procter & Gamble who is purchasing with all the different five entities, it also meant different order processing, invoicing an d deliveries when at the core the five entities are all under the same company.For Procter & Gamble it also a logistical nightmare as they faced issues with high volume of orders which resulted in errors, inefficient deliveries with many trucks delivering to the same customer with less than truckload full and inefficient invoicing by the different entities to the same customer. After Procter & Gamble redesigned the information and physical flows across their five entities, their customers only need to deal with one entity for all its product range and logistical process.The end result is a win-win situation where Procter & Gamble increased its profitability through cost savings and increased customer satisfaction. Their customers also gained with the efficient processes and they are also able to enjoy volume discounts from consolidated orders across their product range. Summary In order to excel, manufacturers might need to produce high variations of products, produce in large volum es to meet economies of scale, be flexible enough to meet the volatile markets demands and run a lean and efficient supply chain to save costs and reduce wastages.In view of such, supply chain management to manufacturing firms are of utmost importance if they wish to compete in today’s ferociously competitive markets. Besides making and selling a product, manufacturing firms need to manage and leverage on supply chain strategically in order to gain competitive advantages. As a result of globalisation and rapid technological changes, manufacturing firms needs to constantly focus on supply chain management to align their internal operations with their external environments.

Duty of care Essay

1.1+1.2 Sometimes individuals may want to do something which could be a risk to their health and safety. Being a staff member means having a duty of care to that person, it includes doing everything possible to keep them safe, but also having a duty to respect the individuals rights and choice, therefore there is a dilemma. It could be that the individual no longer wishes to use their walking frame, but their care plan states that they need it to move from place to place and as a member of staff, their responsibility is to ensure and encourage the use of the walking frame for the individual. In this scenario a risk assessment could be carried out to ensure that it is managed as safely as possible. The risks would need to be explained that are involved to the individual and make sure they understand. The staff could come to a compromise, to use a stick for a while instead, to see how they managed, then monitor the situation. All this should be documented including any risk assessment carried out. If the individual still insists on walking unaided they should sign to say they are aware of the risks involved. Another scenario could be that an individual refuses to take their medication. Remind them of why they take the medication and it’s benefits and again advise them of the risks involved in not taking their medication. If they still refuse, ensure this is noted on their medication record and reported so others are aware if a problem occurs. If the individual insists on doing something which is unsafe or risky that is their choice it must be respected as it’s their right, but there is a duty of care to uphold and everything must be done to keep them safe for their individual’s rights. Conflicts could arise between staff to staff. One staff member may think that there is an issue. An example of this is that a member of staff may think a child is a slow developer, and may need additional support to help them, such as with their communication skills. Another staff member may think that there is no issue the child is just developing at their own pace and that it is normal. Everybody has individual rights, they have rights against the duty of care therefore children and parents have the right to privacy, but it is the staffs duty of care to safeguard, therefore any concerns that may arise about abuse would override their privacy, as the duty of care is much stronger. This has the dilemma of making parent feel  that the staff has taken the duty of care too far, as the duty of care has been overridden their right to privacy, their right still exists to only knows that need to no. It is important that issues are raised in such way that shows concern for a child, and not criticising a parent/carer. If a discussion needs to take place, it needs to be where the staff and parent are alone to remain confidentiality with a clear focus on the child’s best interests. 2.3 There are many organisations that are in place to get additional support and advice about conflicts and dilemmas. Learning support is one of these, having learning support in the setting for children with learning difficulties can be a great help, however if the child does not want to seek the help, the staff can only advise them, not force them, however having them in the setting the child would then know they can seek help from them when needed. Speech and behavioural therapists are another additional support for those with speech impairments and behavioural problems, these can come in the help children communicate and feel a part of the setting, and not feel ‘different’ from others around them. The setting can seek advice from child protection, as if there is a worry about a child, the manager can contact them for advice on what to do and if the concern is a serious matter that needs to be taken care of immediately or not. 3.1+3.2 If a parent/guardian has an issue to raise that involves their child or any aspect within the nursery, they should report this to the manager of their child’s room as soon as the issue occurs. All effort is put it to solve issues that are raised in the setting, complaints can be written or verbal, written complaints are usually replied within three months. There is a framework which the issues will be dealt within. A matter relating to a child may be discussed between the parent and child’s key person or their room manager. If a complaint is remained unsolved, the matter will be raised by the childcare services manager with the appropriate authority and the parent will be kept informed on the progress at each stage of the procedure. If a parent arrives in the setting with a complaint the practitioner should establish if this is something they can deal with personally. If it is, they  can deal with it there and then or make an appointment to see the parent if they are currently otherwise occupied. If it is a matter that needs to be dealt with by a more senior member of staff then the parent can be referred in that direction. When a complaint arises, the setting should find a way to prevent this from occurring again and find solutions to overcome the situation. When dealing with complaints the staff member should always remain polite and see the parents point of view. They should take responsibility for what has occurred by understanding and taking control of the situation. Notes could be taken down for reminders what complaints have been received before and these documentations be kept in a secure place, the complaints that are made from a parent should be kept confidential regarding if it is to do with their child or the setting itself.

Common Elements of Eastern Religious Traditions Essay

Common Elements of Eastern Religious Traditions - Essay Example y Chinese do not consider themselves spiritual but their traditions with local gods and daily practices have provided a sense of religion for them for over a thousand years. In the recent years, there has been an increase in interest between the relationship of spiritualism and business (Rarick, 2009). Daoism, also known as Taoism, has greatly shaped the Chinese way of thinking. Daoism is one of the greatest religious systems in China (Hansen, 2013). A person can be spiritual but not religious. Molloy (2010), views religion as a belief system and focuses on how those beliefs’ expression in different contexts. The meaning of religion differs depending on an individual’s society and upbringing. Religion denotes a particular system of faith and worship and/or the human recognition of a higher power (Park & Paloutzian, 2013). In the Eastern cultures, religion encompasses a set or system of beliefs and practices adhered by a given community, supported by rituals that recognize or worship the ultimate truth, reality or nirvana (Park & Paloutzian, 2013). In the natural world, spiritual relationships are important and are very common as they are part of the human survival (Molloy, 2013). Spirituality connotes the personal and effective relationship with God. It is the domain of spirits; God or gods, souls, angels, jinni, demons and metaphorical extensions to other intangible or invisible things (Park & Paloutzian, 2013). Daoism is traceable to shamanism, which spread in china and Mongolia more than ten thousand years ago. The Dao is the opposing force and energy of the universe, and is the beginning and the end of Daoism. The Dao represents a cosmic principle that permeates all the aspects of creation. The exact founding date of Daoism is unknown, even though there is a belief that the mystic Laozi (Lao Tzu) is the one who developed the spiritual and philosophical orientation of Daoism. According to Laozi, the Great Unity known as Yin and Yang ruled the universe.

Design of the Preschool Essay Example | Topics and Well Written Essays - 750 words

Design of the Preschool - Essay Example Arian Mostaedi offers a convincing illustration of twenty-six successful projects from around the world which are closely linked to the creation of suitable surroundings for young children, in the book Preschool and kindergarten architecture. As the author provides significant illustration of how the physical environment can contribute to the learning of children in preschool and kindergarten, this book offers an important education in designing for the very young. In the book, the author brings under spotlight of the students of designing the innovative architectural practices in relation to teaching, emphasizing safety and environmental conservation. The safety aspect incorporates nontoxic finishes, hidden electrical outlets etc, while the environmental conservation includes solar panels, tanks for rainwater collection, and recycling facilities. In this important book on kindergarten facilities with regard to design and construction, one gains significant idea of form and function within the work of Mark Horton, and the design of "The Little School" in San Francisco, CA USA provides a convincing picture of the entire work of Mark Horton. ... The children's response to the wall was so exceptional that the school organized a summer program on architecture for four-and-five-year-olds." (Mostaedi, 134) Therefore, the architecture of The Little School in San Francisco, CA USA offers an essential illustration of the entire work of Mark Horton and this paper undertakes a profound review of the idea of form and function within the work of Mark Horton based on critical thinking of the book Preschool and kindergarten architecture by Arian Mostaedi. The architecture of The Little School in San Francisco, according to me, is important as it conveys the idea of form and function within the work of Mark Horton becomes obvious to a reviewer, and a former gymnasium with holes in the wall became an enlightened preschool with effective learning environment through the masterful architectural work of Horton. His architectural abilities helped Horton in creating a three-classroom preschool for about 100 children from the former Gymnasium with an S-shaped, canted wall which narrows and widens, made of studs and gypsum board. An understanding of the form and function of the design was essential in the making of this structure and the far-sighted abilities of the architect become lucid to the viewer. "Along the wall are openings for children to crawl through, sit in and peek out. Cantilevered planes jut out to provide spots for sitting or standing. Add colour and the wall becomes an abstract element for which the children constantly invent new uses. 'Open to fantasy, the wall can become a spaceship or a forest,' says Horton, 'a mountain range or a garden, a bear cave or an ocean liner. It is abstract to avoid interfering with the children's

LEADERSHIP THEORY AND PRINCIPLES Term Paper Example | Topics and Well Written Essays - 1250 words

LEADERSHIP THEORY AND PRINCIPLES - Term Paper Example Some of the leadership theories focus on the qualities that distinguish leaders and their followers (Bennis, 1989). In addition, other leadership theories highlight on the levels of skills and an individuals approach towards various aspects of leadership in a particular context in the society. Leadership is a core element of the society because it promotes effective organization, planning, and decision-making processes in the society. On a personal level, I take an evolved approach to leadership based on experiences in different social contexts. In this case, my personal definition of leadership is the ability to stimulate and motivate people to act towards a desired goal or vision. Leadership would not only focus on the goal or vision but also help the workers to rise to their full capabilities while accomplishing the goal or mission of an organization. In addition, effective leadership qualities are developed by establishing an individual’s weaknesses and initiating appropriate measures to promote leadership (Bennis, 1989). The establishment of the characteristics of my weaknesses in the interacting with different people in the society contributes to the development of good leadership qualities. The experience also enables me to develop effective problem-solving strategies in different social contexts. Addition, good leadership is developed through embracing of the challenges an individual faces in inter acting and resolving issues in the society (George, McLean & Craig, 2008). Leadership challenges vary depending on various aspects such as behavioral, psychological and social context. The challenges an individual faces in a particular leadership position are essential in enhancing leadership development in them. In addition, the process of overcoming some of the challenges to effective leadership is crucial in establishing a confident approach to various arguments in a particular context (George, McLean & Craig, 2008). Leadership challenges refer to

'la ci darem la mano' by Mozart from the opera Don Giovanni Essay

'la ci darem la mano' by Mozart from the opera Don Giovanni - Essay Example 6 of Don Giovanni". (Donelan) In this piece Mozart used the elements of rhythm. . He used specific instruments to convey the mood and settings of an opera as he did using this piece. An example of this is Mozart uses the clarinet to set the mood using rhythm. In this piece he used its sensuous and different timbre for astounding effect. He frequently associated the clarinet with female upper class characters. He cleverly uses the elements in this piece for example it is the clarinet's first appearance following the overture in Don Giovanni and is reserved for Donna Elvira's entrance. (Donelan) In conclusion, it can be said that Mozart used the elements in Don Giovanni to produce an effective setting for the text. He brilliantly does this in all of his works just as he did in the piece under discussion. If familiar with Mozart's work this should not be a new premise. He was a brilliant and innovative composer. He is known as one of the most compelling figures in music for over two hundred years.

David Suzuki, The Big Picture- the enviormentalist dilemma Essay

David Suzuki, The Big Picture- the enviormentalist dilemma - Essay Example He talks of the different aspects of this problem and the possible defense mechanisms that the planet may have in order to combat the encroachments of technology. For Suzuki, it is also important that one understands the importance of mankind’s position on the planet. The fact that man is one of the many species that exist on this planet is significant for Suzuki. There are several new theories that Suzuki puts forth including the idea that it is necessary for the ecological to be quantified in the economic sense of the term. This would then put a certain amount of pressure on people to create a world where the ecology is valued in terms that are familiar to the current market economy. This then makes us aware of the importance of creating a world where the ecology is not a dispensable commodity but something that provides us with an understanding of man’s relation to his environment and other creatures who have equal rights over the resources of the earth. Suzukiâ€⠄¢s main argument is that the ecology needs to be given his due and integrated with the scientific endeavors of man and in the economic framework of the world, without which there would be no sustainable growth in the world in any sector. One of the main arguments that Suzuki makes throughout his career is that mankind needs to come to terms with the fact that it exists on the earth and would not be able to survive without the earth being a place that can sustain them. The disconnect that man reveals when it comes to the earth can be seen from the fact that dirt is always regarded as something that is undesirable. However, this dislike for dirt is oblivious to the fact that whatever grows on the earth takes root in dirt and can be seen to draw its nourishment from the very dirt that is regarded with such contempt by man (Mast). This then reveals an attempt on the part of Suzuki to look at the tiny things in one’s life that indicate the attitudes that one holds towards the env ironment. Such attitudes then create a situation where the ecology is undervalued and not given its proper due. Its life-sustaining quality is then obfuscated and not given due importance. Despite man’s advancement in terms of science and technology, there is still a lot that needs to be done in terms of the conservation of the environment. The conservation of the ecology is a must for the sustained development since the resources necessary for development ultimately comes from the environment itself. This can be seen from this statement that is made by Suzuki in The Big Picture- †¦all of these things that so dominate our headlines and our lives- all of these things are merely social constructs created by humans. Ultimately they still depend on something else: the continued existence of a stable and healthy planet to provide us with the basics of life. Without a healthy planet to cleanse our wastes and provide us with resources, we will wither. Unless we can find a way t o live in balance with the natural systems that sustain us, our species will ultimately reach a dead end (3). The ideas that are expressed in this passage are important as they do not suggest that development of the kind that is fuelled by technological advances is insignificant. What it does suggest, however, is that there needs to be an awareness of the environmental impact that certain programs of development have. According to Suzuki, one must not devalue science and its effects on mankind. However, one must

Effects of Radiological Dispersion Device Research Paper

Effects of Radiological Dispersion Device - Research Paper Example Effects of Radiological Dispersion Device In recent times, the U.S, Great Britain and most of Europe have seen the use of radiological dispersal devices by terrorists as a key insecurity threat (Runge and Buddemeier, 2009). In addition to the threats, the impacts that come with the detonation of the radioactive devices in public places have some effects depending on a number of factors like wind and temperature among others. The possibility that terrorists can employ a radiological dispersal device in a public area has even enlarged the concerns of governments and the public regarding such weapons. A Radiological Dispersal Device (RDD) is a gadget aimed at disseminating radioactive materials with the purpose of causing destruction, injuries and damage to the habitats around the detonation site (Radiological Dispersal Device, 2005). A suitable example of an RDD is a dirty bomb which is usually made of explosives that disperse radioactive materials upon detonation which is contrary to the norm that RDDs do not require explosives. RDDs are usually used with intent to cause injuries or damage, which are essentially the goals of terrorists. According to Radiological Dispersal Device (2005), an RDD is any kind of device that results in the intentional dissemination of radioactive matter with no nuclear detonation. The mode of dispersion of these radioactive materials is usually via a dirty bomb which explodes to release radioactive dust plus radioactive and nonradioactive shrapnel (Runge and Buddemeier, 2009). The effects of the explosion include radiation contamination, exposure to radiation in certain circumstances, physical injuries, burns, panic and fear. Other methods of dispersion include active or passive dispersion of sources of radioactive materials that are unsealed with contamination of the people coming from the air, food, soil or water. Harper, Musolino and Wente (2007) argue that the effect of RDD explosion is local although the psychological impact it has is worldwide as well as the attention of the media; hence an overestimation of the effects of the exposure may result. In addition, Musolino and Harper (2006) affirm that RDDs are usually located or rather placed in unexpected areas; thus when they explode, the explosion and the selected location will surprise many. The long-term effect of radioactive dispersion will be easy to realize but the short-term may be hard as it takes time to discover the contamination’s source. The initial indicators of contamination include prior threats, routine monitoring techniques and activities to identify the first responders, monitoring of activities of suspected groups by the intelligence community or plainly by chance. Urban population is usually high in many nations of the world. It is for this reason that terrorists least prefer RDDs since it is tricky to design one that will administer plentiful doses of radiation to result in immediate health defects in a densely populated area (M anagement of Terrorist, 2001). As a result, Tochner and Glatstein (2008) debated and concluded that an RDD is likely to be used to; i. Cause uneasiness in people who are of the view that they have been exposed or are exposed to the radiation. ii. Disrupt the lives of people by contaminating the facilities they use or the places they work or live. The experts went ahead to determine the factors that affect the efficiency of the RDD attacks which include weather conditions, local topography, physical and chemical composition of the

In African American women who have delivered live infants, what is the Essay

In African American women who have delivered live infants, what is the effect of prenatal care, in comparison to no prenatal care, on infant mortality rates within the first year of life - Essay Example innovative service initiatives, and implementation of MCH programs, policy analysis topics, advocacy issues and professional development of medical and healthcare practitioners in the MCH area. As such, the Maternal and Child Health Journal is important because it can be used as a tool for practitioners, academicians and researchers in the areas of public health, gynecology, prenatal medicine, neonatology and obstetrics. The Maternal and Child Health Journal is sponsored by different organizations that include the Association of Teachers of Maternal and Child Health (ATMCH), Association of Maternal and Child Health Programs (AMCHP) and CityMatCH. The above description makes the Maternal and Child Health Journal an essential tool to which the group plans to submit the final manuscript. First, the journal is appropriate for the group because it covers the area of demography specifically in maternal and child health area. This makes it a specific journal that will be easier for the reader to find information on maternal and child health demographic issues. The group intends to carry out research on the effect of prenatal care, in comparison to no prenatal care, on infant mortality rates within the first year of life in African American women. Therefore, the topic of the research shows that it qualified to be published under the Maternal and Child Health Journal. Prior research into the group’s topic shows that African-Americans have 2.3 times the infant mortality rate compared to non-Hispanic whites. They are also four times likely to die as infants because of complications related to low birth weight compared to non-Hispanic white infants. It has also been shown that African Americans are 2.3 times more likely to begin prenatal care in their third trimester or not go for prenatal care at all compared to non-Hispanic white mothers (Centers for Disease Control and Prevention, 2013). Compared to women from other racial/ ethnic groups in America, infants born to

Onion DNA Extraction Essay Example for Free

Onion DNA Extraction Essay DNA(deoxyribonucleic acid) is found in every living organism. It provides the information and instructions to build and regulate cells in organisms. The information it contains is used when organisms are being reproduced. It is made up of two polynucleotide chains known as DNA strands. Within the two chains there are four nucleotide units: adenine, thymine, cytosine, and guanine. Materials and Methods An onion was cut into pieces and placed in a blender with 50 mL of water and blended for one minute. Once blended, 20 mL of 25% saline solution and 10 mL of liquid detergent was added to the mixture and blended for 3 minutes. The mixture was then added to a flask and placed into a bath of hot water at 42? C for 10 minutes. The mixture was then removed from the hot water bath and filtered using a cheese cloth (dryer sheet) into a beaker. In a test tube (test tube â€Å"B†), 10 mL of 90-95% ethanol was placed into a beaker filled with ice. Then 10 mL of the filtered mixture was then placed into a test tube (test tube â€Å"C†). Test tube â€Å"C† was tilted at an angle and the ethanol from test tube â€Å"B† was slowly poured into test tube â€Å"C†. After 5 minutes, a white layer was formed between the onion-detergent mixture (test tube â€Å"B†) and the ethanol (test tube â€Å"C†). A plastic pipette was used to remove the white layer from the tube and placed into a micro centrifuge tube. The micro centrifuge tube was centrifuged at 10 K rpm for 1 minute. The supernatant in the tube was then removed and discarded only leaving the white pellet that was formed at the bottom. Results During this experiment, the DNA of the onion had formed at the bottom of the micro centrifuge tube.

The more horrific the report, the more likely it is to capture the attention of the public, which obviously secures plenty of profit for media barons. Is our increasing reliance on an institution that relies on sensationalism to create profit unwise, as this could well mean that the facts they report lack truth? The media reinforces social myths by selective reporting, and thus presents a distorted view ofreality. This could be leading to an increasingly misconstrued public view of certain crimes. The media is a very powerful influence on the way in which we behave and how we view the world, therefore it is important that it shows a realistic picture of what is taking place in our society, otherwise we will gain a false perception of aspects such as crime. Is the media really portraying crime as it truly is, or is it selectively reporting the most colourful events in order to secure audiences and therefore profit? It is important to understand that there are many crimes that are completely ignored by the media, as they are not seen as ? newsworthy?. Usually only those that will capture public attention are mentioned. This means that the crimes that fill our screens and pages are usually violent or shocking in nature. From a functionalist perspective this can serve a positive function, as the deviant behaviour makes ordinary people feel safe in the knowledge that they are morally better than the criminal, and reporting of crimes and subsequent punishments can also serve as a deterrent to others and a good method of reinforcing the social order. However, there is also a certain degree of bias present in all reporting that stems from the integrated norms and moral background of the journalist involved. It is almost impossible to be completely objective when reporting, and most journalists will slant their stories to appeal to the widest possible audience. This is theorized in the hegemonic model, and works on the basis that the majority of journalists are likely to be white, male and middle-class and will therefore bring with them to their stories their own similar set of norms and values, be this unconsciously or otherwise. The editors will also carry out a selection process on the stories before they hit the public view; therefore it is highly unlikely that any crime report reaches the news in an unbiased state.? Journalists also tend to use a set of stereotypes, which serve to easily identify ? types? of people and reduce complexities of character to a series of ? bad guys? and ? good guys?. These can lead the public to make quick judgments, which may not be based on true fact.? The media? s presentation of stereotypical images can change the public opinion on certain groups in society, and may create a false picture of them that may be harmful. The groups most often portrayed as criminal are the less privileged and minority groups such as those from ethnic minorities. Because our lives are so deeply influenced by the media we begin to see the portrayal of these groups as a reality, and this may cause crimes committed by other groups or individuals (such as corporate crime in the middle class) to be overlooked or seen as less serious.? In addition, the police can make use of the media to help maintain social order by choosing what to tell reporters, as many news stories use police accounts as a major source for their information. A good example of the media distorting aspects of crime is shown with the reporting of women involved in criminal activity. The common media portrayal of women is more passive and much less inclined to commit crime, and when they do it is seen as less violent or shocking in nature, or as influenced by a stronger male personality, for example Myra Hindley was commonly said to have been under the influence of Ian Brady when the horrific Moors murders were committed. Media coverage usually concentrates on the most violent and shocking aspects of crime. This can often be far from the truth, and puts the public in fear when in reality there is a tiny chance of them falling victim. Listening to the news, it appears that the country is riddled with serial killers and rapists however official crime statistics would show that this is not the case. Reporting like this can lead to mass panic and fear across the country, and this aspect was investigated further by Stanley Cohen in his book ? Folk Devils and Moral Panics? where he studied the 1960s mods and rockers conflicts. The media? s handling of the fights between the rivals groups made it sound as if Brighton was full of riots and was a very dangerous place, when in reality this was a false picture of events. However, these stories grabbed the headlines, and as a result appealed to a large audience and gained lots of attention with the public. At the moment there is lots of media coverage about murders in Cornwall, and about the girl who was kidnapped and murdered on Dartmoor. The way these are reported makes people fearful that there is a serial killer on the loose, when in reality there is probably little chance of this happening to them and they should be more concerned with the more common but less ? colourful? crimes that threaten society, most of which would be much more obvious if the public were able to look at official crime statistics. This viewpoint fits in well with the idea of the media as a manipulative entity that is ideologically biased and therefore bases its selection of news on this fundamental bias. This manipulation theory is Marxist in origin and works on the idea that the public are passive and absorb the information that the media presents them with without question, and that the media consist of the ruling class who use media channels to perpetuate their views and opinions in society. Official statistics paint an interesting picture of the true nature of crime levels in society. It is a fact that crime rates have actually remained stable over the last year, after experiencing a period of decline. This challenges the constant media message that crime is everywhere and on the increase. When people were interviewed about crime rates many of them believed that crime was well on the increase, as result of a ? heightened degree of press coverage which particularly focused on a claimed rise in crime.? (Jon Simmons in the Home Office Report 2002).? It is a well-known fact that the media tend to emphasise aspects and types of crime that are violent or shocking, such as murder and rape, which affects the general population by creating huge worry about occurrences of violent crime when it is a statistical fact that one is over four times more likely to fall victim to burglary. Another form of media that can, and often does, present distorted representations of crime are television shows such as The Bill, Merseybeat or reality shows such as Crimewatch. For example Crimewatch focuses on catching criminals who have carried out violent crime and places little or no emphasis on occurrences of burglary or more ? normal? crimes, even though this type of crime is much more frequent. The Bill shows many incidents of violent crime, however also tends to show other less ? newsworthy? forms of crime such as theft which is a more realistic approach. coac ac . r se . ac . ac . w or. ac . . ac .k inac foac . ac . . There are a number of media influence models that attempt to explain the extent and nature of media influence. The manipulation theory presented earlier is one of these theories; however there are others that attempt to explain the media? s effect on society in different ways. The pluralist model argues that the public are not passive receptors but active participants with the ability to choose and form their own opinions from the vast variety of information presented by the media, whether about crime or about other social issues. The media only serve to reinforce the existing values that people possess. Tversky and Kahneman suggest that the easier it is to recall or imagine an event, the more likely we are to see it as risky or as frequent in occurrence (Tversky and Kahneman cit. 1994: 303). Therefore if this is correct then constant media coverage of violent crimes could lead us to believe that such crimes are the ones most likely to affect us. Mass media reporting can also serve as a substitute for direct experience, however research into this supports the pluralist model by showing that people are usually active consumers and interpreters rather than passive recipients. The issue at hand seems to be the growing difference between the way the public perceive crime and the reality as shown by official statistics. For some reason, society has a far greater fear of murder and other violent crime than is justified by the actual number of occurrence, when in reality there is far greater likelihood of incidences of burglary or car crime. So where do these fears stem from? The answer appears to be that they come from the way in which the media report crimes and how they select the most newsworthy aspects so that more papers will get sold and so viewing figures will increase. In conclusion it is an unavoidable fact that our society is so immersed in the media that its influence is hard to get away from. To a large extent, media does form our social world, however it is also true that people are active interpreters of information, and are able to utilize their own opinions on events and stories shown by the media. We are only taking in what the media offer to us not the real truth about what is happening. It is very easy for our conceptions of crime to be distorted by the way that the media portray it, as the only information we are receiving on the events is that which comes from the media. However if people really are actively interpreting and thinking about the true nature of crime levels, while attempting to broaden their horizons of information, then they will be more aware of the reality of the situation and our conceptions will be far less influenced by media constructed images and opinions.

Helicobacter Pylori Treatment and Rosacea

Helicobacter Pylori Treatment and Rosacea Running title: Helicobacter Pylori Treatment and Rosacea Parviz Saleh1, Mohammad Naghavi-Behzad2, Hamdieh Herizchi3, Fatemeh Mokhtari3, Mohammad Mirza-Aghazadeh-Attari2 , Reza Piri4* 1- Chronic Kidney Diseases Research Center, Tabriz University of Medical Sciences, Tabriz, Iran 2- Students Research Committee, Tabriz University of Medical Sciences, Tabriz, Iran 3-Department of dermatology, Tabriz University of Medical Sciences, Tabriz, Iran 4- Medical Philosophy and History Research Center, Tabriz University of Medical Sciences, Tabriz, Iran Effects of Helicobacter pylori Treatment on Rosacea: a Single Arm Clinical Trial Study Abstract: Rosacea is a chronic dermatologic disease. Helicobacter pylori has been discussed as one of its causative factors. In this clinical trial study, it was tried to evaluate the effect of H. pylori standard eradication protocol on the rosacea clinical course. In this single-arm clinical trial, patients with approved H. pylori infection based on serological studies were assessed to examine rosacea existence. Then, the patients with concurrent rosacea and H. pylori infection were included in the study and underwent a standard Helicobacter pylori eradication therapy. Rosacea was evaluated using Duluth rosacea grading score at beginning, 2 months later, and at the end of the trial (day 180). Of 872 patients with positive H. pylori, 167 patients (19.15%) manifested the clinical features of rosacea. The patients with concurrent rosacea were younger (p Keywords: Rosacea, Helicobacter pylori, Prevalence, Eradication, Treatment Effects of Helicobacter pylori Treatment on Rosacea Introduction: Rosacea is a chronic dermatological disorder mostly affects facial convexities, which is characterized by telangiectasia, flushing and papulopustular changes (1, 2). These findings tend to be in cluster patterns, which allow identification of different subgroups of patients. In other words, rosacea includes a wide spectrum of dermatological manifestations with different severities (3-5). Pathogenesis of rosacea is thought be related to vascular changes, but the main process of pathogenesis for rosacea is still unknown. A combination of dermal connective tissue damage and vascular dysfunction consisting endothelial damage, impaired reactivity, and autonomic dysfunction has been proposed (5-9). So researchers have always tried to reveal the pathophysiology process by proposing possible pathogenic factors such as solar irradiation, sensitivity to noxious stimuli, change in redox status, and the presence of parasitic mites (Demodex folliculorum) (10-14). The role of Helicobacter pylori related gastritis in the pathogenesis of rosacea has been also a subject of controversy. Diverse prevalence of H. pylori infection has been reported among rosacea patients (15-21), ranging from zero to 100%. Some studies have suggested that rosacea could be considered as an extra-gastric symptom of H. pylori infection or reported improved rosacea clinical course post H. pylori eradication (22) (23), while others concluded no significant relationship between H. pylori infection and rosacea (24, 25). Based on our literature review, no confident and precise conclusion has been made about any change in the clinical course of rosacea after H. pylori eradication yet today. So the present clinical trial aimed to evaluate changes in the clinical course of rosacea after H. pylori eradication by standard treatment protocol. Subjects and Methods Study design In this single-arm clinical trial which was conducted in clinical-educational centers of Tabriz University of Medical Sciences (Tabriz, Iran) from May 2013 to November 2015, patients with proved H. pylori infection based on serological study were screened for evaluation of concurrent rosacea disease. Then, the patients with concurrent rosacea clinical presentation and H. pylori infection were enrolled into the study. Considering sample number limitation, sampling was performed during a year to calculate sample size, then study power was calculated 0.85 according to that number of samples. Rosacea severity was graded using Duluth rosacea grading score (26) before and after H. pylori eradication protocol. Finally, the patients were examined 2 and 6 months after medication, to compare dermatological findings of rosacea with primary findings. All participants were provided an informed written consent, and the study protocol was in compliance with the Helsinki Declaration and was approved by the Ethics Committee of Tabriz University of Medical Sciences. In all stages of study patients information were anonymous and based on codes and patients could refuse to take part in the study at any stage. This study is registered at Iranian Registry of Clinical Trials (IRCT2015051418946N3). Study population All patients who were 20-65 years old, with confirmed H. pylori infection and active rosacea, attending clinical-educational centers of TUMS were included in the study. Prior H. pylori eradication treatment, the existence of any other dermatologic problem, allergy to clarithromycin or omeprazole, antibiotic therapy within past 2 months, topical treatment of rosacea in past 3 weeks, history of hospitalization in past 6 months, pregnancy and breastfeeding, patients were considered as exclusion criteria of the study. H. pylori infection evaluation H. pylori stool antigen test was implicated to confirm H. pylori infection before enrolling the patients into this study (day 0) and to confirm H. pylori eradication (day 60). Stool samples were collected in a standard container. In the laboratory, using an applicator stick 4-5 mm of stool was transferred in a diluent vial, then it was vortexed for 20 seconds. Then, 4 drops of vial were dispensed in ImmunoCard STAT HpSA kit (Meridian Diagnostics, Inc., OH, USA); positive predictive value of this test was 89.3% based on literature (27). The positive and negative results were concluded based on the manufacturers recommendation. Rosacea evaluation Rosacea severity was evaluated using Duluth rosacea grading score (26) at beginning (day 0), 2 months later (day 60), and at end of the trial (day 180). Dermatology team examined rosacea based on detecting primary and secondary signs and symptoms of rosacea and graded them as absent, mild, moderate, or severe (0-3), based on the Duluth scoring system. Primary features of rosacea included: flushing (transient erythema), non-transient erythema, papules and pustules, telangiectasia. Secondary features included: burning or stinging, plaques, dry appearance, edema, ocular manifestations, peripheral location (present or absent), phymatous changes. Finally, rosacea condition was compared in day 0, day 60, and day 180 by the same team. H. pylori treatment Standard two-week triple therapy was administered to eradicate H. pylori, including metronidazole 500 mg orally twice per day, clarithromycin 500 mg orally twice per day, and pantoprazole 40 mg orally per day. Primary and secondary outcomes The primary outcome was the severity of rosacea before and after H. Pylori eradication. Secondary outcomes were H. Pylori eradication rate and prevalence of rosacea among patients with H. Pylori and demographic differences between H. Pylori positive patients with rosacea and without rosacea. Demographic and outcome measurement All demographic information was collected at patients enrollment time. Patients rosacea stage was evaluated on day 0, 60, and 180, then they were compared. Same dermatology team reevaluated clinical course of rosacea to decrease inter-observer error. Statistical methods Statistical analysis was performed by SPSS software package, version 16.0, for windows (SPSS Inc.). Quantitative data are presented as mean  ± standard deviation (SD), while qualitative data are demonstrated as frequency and percent (%). Paired sample t-test, chi-square, and Friedman test were used for analysis of data. Mann-Whitney U test was used to compare between groups and Wilcoxon ranked sum test was used to compare within groups. Probable confounding factors were considered as inclusion and exclusion criteria. However, some factors which could have been confounding factors were analyzed using multivariate analysis but they were not presented in results the section. P value less than 0.05 was considered statistically significant. Normal distribution of data was assessed using Kolmogorov-Smirnov test. Results In the present study 872 patients with positive H. pylori stool antigen were assessed by dermatologists team. Of 872 patients, 167 patients had clinical features of rosacea. Some demographic information about patients is shown in Table 1; of all patients with a positive test for H. pylori, patients diagnosed with rosacea had lower ages (p>0.001) and the difference in gender composition was also statistically significant (p=0.034); in this conclusion, multivariate analysis was used. Based on the results, rosacea prevalence among patients with positive H. pylori stool antigen was 19.15% (167/875). Of 167 patients with positive H. pylori stool antigen and rosacea, 17 patients rejected to take part in the study while 150 patients agreed. Of 150 patients who underwent H.pylori eradication therapy, 138 (92%) had negative H. pylori stool antigen (successful treatment) at the end of the trial. Rosacea Duluth score at day 0, 60 and 180 was 15.55 ±4.34, 14.11 ±3.96 and 12.57 ±3.62, respectively; the differences between all stages were statistically significant (p Based on Wilcoxon signed-rank test, comparison of primary and secondary features of rosacea between stages of study is shown in table 3; Of secondary rosacea features, burning or stinging, plaques, dry appearance edema and ocular manifestations the difference between two stages of study were mostly significant; but the differences for peripheral involvement and phymatous change were mostly not statistically significant. Discussion Rosacea as a chronic dermatological disease, with an almost unknown pathogenesis process so far, has been the subject of many studies. One of the proposed pathogenic processes attributed to rosacea is gastric infection with H. pylori, so many researchers have tried to examine this association by trying to investigate the correlation between H. pylori infection and rosacea or by observing changes of rosacea after H. pylori eradication. Based in the present study, Prevalence of rosacea among H. Pylori positive patients was 19.15% in this study, which seems as twice as the highest reported rate in other populations, ranging from 1-10% (2, 28-31). This different has been correlated to various variables including race, culture and diet of these. In a study by Argenziano et al. potential association between rosacea and serological evidence of H. pylori infection was investigated and they concluded that there is a significant association between rosacea and H. pylori infection (32), while A bram et al. evaluated several suspected risk factors for rosacea and concluded that there was no statistically significant differences between rosacea patients and those of control group (33). Patients with rosacea and H. pylori infection had female gender predominance and lower age in comparison to those suffering only H. pylori infection. H. pylori cure rate after routine triple therapy was 92%. During 6 months of follow-up, H. pylori eradication among those who had rosacea and H. pylori infection led to a significant improvement in rosacea condition based on Duluth score grading. There was a significant decrease in intensity of almost all primary and secondary criteria except phymatous changes, telangiectasia, and peripheral involvement; this difference in phymatous changes, telangiectasia, and peripheral involvement might be due to the more time taking nature of these criteria to be resolved. Based on the literature, diverse conclusions have been made regarding rosacea resolution after H. pylori eradication. In a study by Szlachcic et al. investigating the link between Helicobacter pylori infection and rosacea, it was concluded that after H. pylori eradication therapy among patients with rosacea and H. pylori infection, H. pylori cure rate was 97%, and in 85% of patients the symptoms of rosacea decreased markedly or disappeared within 2-4 weeks (22); although H. pylori cure rate in the present study is less than that reported in this study, the effect of H. pylori eradication on rosacea is similar in both of the studies. In another study conducted by Rojo et al. on the role of H. pylori in rosacea and chronic urticarial, it was concluded that H. pylori eradication led to a significant improvement both in rosacea (75.6%) and urticarial (85.7%) when compared with control group (22%) in 4 weeks (34); results of that study is similar to what was concluded in the present study, although no precise description of clinical features of rosacea was presented after treatment. On the hand, Bamford et al. in a study investigating effect of treatment of H. pylori infection on rosacea concluded that rosacea was significantly improved after H. pylori eradication, although this improvement was also significant in control group, the difference between the improvement of rosacea was not statistically significant between intervention and control group (35); this fact that both groups had significant improvement in rosacea totally undermined the association of H. pylori infection and rosacea which was concluded in the present study, also in this article the improvement was attributed to probable placebo effect. In another study by Herr et al. relationship between H. pylori and rosacea was examined by evaluating the response of patients with rosacea to H. pylori eradication, and they concluded that there was no statistically significant change in rosacea condition both in intervention and control group, although papulopustules had significantly decreased in interven tion group comparing baseline and follow-up (36), which is the only improvement detected after H. pylori eradication in this study, but in the present study besides improvement of papulopustules, almost all the other clinical manifestations of rosacea had improved. In a study by El-khalawany evaluating the effect of H. pylori eradication in rosacea subtypes it was concluded that H. pylori eradication led to a significant improvement in rosacea, where papulopustular subtype improved significantly more than erythematotelangiectatic subtype (37); these results are similar to the results of present study, since in the present study almost all clinical manifestations of rosacea had decreased while no statistically significant change was shown about telangiectasia. According to the mentioned literature, different conclusions have been derived from studies about the efficacy of H. pylori eradication in rosacea treatment; ranging from significant improvement in rosacea (22) or significant improvement between baseline and follow-up but not when compared to control group (35) to no significant improvement in rosacea. One of the reasons which might be responsible for these diverse conclusions is multifactorial nature of rosacea where ethnic group, bacterial subtypes or genetics might be other confounding factors. One of the main limitations of this study was lack of control group, so it might have affected this study to prevent coming to a precise and confident conclusion, also this might have led to undermining probable placebo effect of administered treatment. The main thought behind not including a control group was not willing to deprive patients of H. pylori treatment where their H. pylori infection had already been proved. Another factor which could have resulted in a more precise and reliable conclusion was including possible confounding factors such as gender, ethnic groups, and occupational environment status and analyzing rosacea improvement while taking confounding factors into account. In conclusion, the present study indicated that prevalence of rosacea among patients with H. pylori infections is slightly more than what literature attribute to different populations, it also showed a statistically significant improvement in rosacea when Duluth scores were compared between baseline and follow-up. Considering the present controversy about the association of H. pylori infection and rosacea, it is suggested that further clinical trials considering multifactorial nature of rosacea take all possible confounding factors into account, also as far as rosacea is a dermatological condition with different manifestations, recognition of alterations in the dermatological pattern of rosacea might lead to a more confident conclusion.

interior with a book :: essays research papers

The painting I chose to critique is Interior with a Book. This painting was instantly appealing to me. The painting focuses on an empty chair in a room next to a table. On top of the table there is a cup closest to the chair. Next to that there is an open book, and on the right edge of the painting there is an empty plate on the table. If you look out the window, you will see a big green field. The reason this painting was so appealing to was because this field looks like a golf course to me. I can see a sand trap on the left edge of the painting close to the house the picture is taken from. Also, there is what appears to be a winding path coming down the center of the field which could be a cart path leading to a green.   Ã‚  Ã‚  Ã‚  Ã‚   The painting appears to be done in oils which would be a good choice for this painting. Painting with oils allows the painter to blend colors together and adds a lot of depth to the picture. This is imperative for many of the objects in this pai nting such as the field and the sky. Interior with a Book looks to be a representational painting but one could argue that there are some parts that are nonobjective or abstract. A person can see most of the images in the painting and they are forms in the natural world, thus making it a representational painting. However, there are two black spots that appear to be outside the window that I cannot make out exactly what they are, therefore maybe making this part nonobjective. On the other hand, with this picture looking so much like a golf course to me these two black spots could represent distorted golfers getting ready to chip in a ball, making this part abstract. One of the properties of this painting is that the field is made up of an analogous harmony. The field is made up of green, yellow-green, and yellow. The effect of this is that the field appears to have different shades of green grass, such as a rough, a fairway, and a green. Another property of this painting is the asymmetrical balance. The painting is heavier to the left because the chair, being the central image in the painting, is to the left of it.

George Orwells Nineteen Eighty-Four 1984 :: essays research papers fc

1984 is a political parable. While Brave New World describes a future of everyone getting exactly what they want, George Orwell takes this in the opposite direction with a description of how the world most likely will be: mindless, loveless, unfeeling followers of nothing. The first paragraph of the story already foreshadows of what is to come with a description of Victory Mansions, the home of Winston Smith, the protagonist of this story. It tells of the â€Å"swirl of gritty dust†¦ The hallway smelt of boiled cabbage and old rag mats.† Even the names of places are depressing. He lives in the province of Airstrip One, the city of London, and in the country of Oceania. The other two countries are Eastasia and Eurasia. Big Brother, a fictional or real person—no one really knows—is the leader of this miserable system of Ingsoc—English Socialism, that is. No one is allowed to hold ideas different from those of the official propaganda outlet: Minitruth. T o enforce these laws, Big Brother uses many means, the first and foremost of these being the Thought Police, a corps of law officers who monitor the populace through undercover agents, infinite amounts of surveillance cameras and hidden microphones, and a two-way television screen that can be turned down, but never off. A new language is also being introduced to retard thought: Newspeak. This new English dialect uses shortened and compacted forms of modern day words that subconsciously facilitate the assimilation of misinformation through the omission of instances such as â€Å"science†, â€Å"freedom†, and â€Å"religion.† This, obviously, is a very bleak existence, and Winston, the oddball out, realizes it. Two characters besides Winston are brought into the plot. O’Brian is an extremely famous party member who Winston suspects is really a traitor member of the underground â€Å"The Brotherhood† led by the ex-Party member Goldstein. The other is a young girl, Julia, who he hates for her commitment to an Anti-sex league, and suspects of spying on him. And so, depressed, lonely, and ever conscious of the Party’s Minitruth slogan, â€Å"Who controls the past, controls the future: who controls the present controls the past,† he begins to search for the truth of the past, the rise to power of the current system, and, overall, the truth of his existence. The plot develops as he finds Julia is actually in love with him, and O’Brian seems to be making overtures to Winston on the subject of The Brotherhood.

Role of the Quakers in Uncle Toms Cabin by Harriet Beecher Stowe Essay

The Quakers and Uncle Tom’s Cabin     Ã‚  Ã‚           Ã‚  In this paper, I will examine the choice of using the Quakers as the angelic figures that become the saviors for the black race during the slave movement in Uncle Tom’s Cabin. While examining this topic, Harriet Beecher Stowe’s background of Puritanism becomes the focus for her motivation to change the world around her and her strict discipline of keeping spiritual values as part of her daily existence. The next stage to be discussed is her conversion from conservative Calvinist views to liberal ideals of social reform. This reform captures the spirit of Transcendentalism, the idea of the individual as a divine being changing society to meet with those ideals. Finally, I will touch on the belief of the Quakers and their history and how they became the model of godliness that is portrayed in Stowe’s novel.   In the Haggadah, God creates the world by his word, the twenty-two letters of the Hebrew alphabet descending from the crown of God engraved with a pen of flaming fire on the mind of Man (Barnstone 15). Many great writers strive to tap into this inspiration of divine light or intellectual genius to produce works of literary art. The written word from these writers possessed enough power to start revolutions, change public sentiment, and alter the rational thinking of the times. One such writer that changed historical events during the American Renaissance is Harriet Beecher Stowe. Her literary masterpiece, Uncle Tom’s Cabin, caused such enlightenment of the general public to push the United States into Civil War to emancipate the black race from the bonds of slavery.

Cameras in public areas Essay

Today, we see a lot of school violence happening. To stop or prevent these violence, we should set up video cameras in public areas in schools. More security will reduce the number of violence in school. People will act and do things more carefully and it will prevent students from getting hurt and provide better learning conditions in schools. Campus security and safety is an important feature of postsecondary education. The Department of Education is committed to assisting schools in providing students nationwide a safe environment in which to learn and to keep student, parents and employees well informed about campus security. At present, the balance is thoroughly tilted towards efforts to effect tough safety and drug policies in the schools and against any extension of the current scant constitutional rights students enjoy. As the preoccupation with drugs and gang paraphernalia in the schoolhouse has escalated, school searches of students and seizures of their property in accord with the Fourth Amendment comprise a cutting edge issue for the courts and school authorities. The video cameras will prevent or stop the school violence. By locating them in public areas of schools, it will not violate any private things going on students’ lives in schools. The video camera will detect fights in the school, prevent fights by recognizing problems that are happening and building up among students, also detect any harmful weapons or materials that are not allowed in school properties, such as knives, guns, alcohols, drugs, etc. Some might argue that it will totally destroy their privacies, but there is no privacies to be destroyed. The video cameras will basically placed on hall ways and all students are got to do on hall ways are just walk and go to the next class or bathroom. Also some might think that that is why the teachers and hall duty people are for, but they have limits. They will not be able to catch all of obligations or problems building up among students, illegal materials in school, and vandalisms. The teachers or hall duties might just turn around for something and any incidents might happen and they might not be aware of those. So it is necessary to set up video cameras in public areas of schools.
