Even though the children play in the street it cause a safety risk to drivers that don’t speed or drive wreck less do to the children running in and out of the streets without looking for cars. The children are our future and they need to be protected. When a person is looking to buy a future home they want to see a nice neighborhood that looks respectable and not as if it’s a bad neighborhood. The appearance of a home in my belief can say a lot about the people who live there. Someone who takes care of their home for example pressure washing, not trash in yard, paint nicely applied. Also there are some resident that don’t have the money but the residents should do as much as they can. To give an example of this a resident in my neighborhood has fixed the garage door which is tilted half way closed and it’s not very appealing. The appearance of a residents lawn as well as home its self make a community. A yard or lawn care should at the minimum have the grass mowed. The plants should be not over grown or deceased. Living in Florida the grass isn’t always...

Most of these institutions exist thanks to donations made it by average people and not government assistance. Every day there is more people living on the streets and the help is simply not enough, even when these kind of institutions exist. The people which suffer of poverty even when we see them like a kind of dog in the street, they are human and they want a decent life like normal people. Is normal to say that those poor people are living on the streets by their own choice, but like I said before, that is ignorance. That people suffer a lot of things, even things that we never going to feel, for example the hungry . The sad of these situations is that most of these people is...

...Task 1 LO 1.1 All high-level programming languages support the concept of data types. A data type defines a set of values that a variable can store along with a set of operations. Data types are used to store various types of data which is managed by program. Data type attaches with variable to determine the number of bytes to be allocate to variable and valid operations which can be performed on that variable. Although C has several built-in data types, it is not a strongly typed language, as are Pascal and Ada. C supports various data types and here some common data type as character, integer and floating-point types. C defines five foundational data types as defined below: ▪ character ▪ integer ▪ floating-point ▪ double floating-point ▪ valueless These are declared as by char, int, float, double, and void, respectively. These types form the basis for some other types also. The extent and choice of these and data types may contrast amongst processor natures and compilers. However, in all belongings an object of type char is 1 byte. C stores character type inside as an integer. Each character has 8 bits so, we can have 256 different characters values (0-255). Character set is used to map between an integer value and a character. The size of an int is ordinarily the same as the word length of the implementation setting of the program. C has 3 classes of integer storage namely short int, int and long int. All of these data types...

Project Managers always undermine the impact the testing activity has on the Project Cost and Schedule. Hence the testing activity is usually unplanned and uncontrollable. As the project manager assumes that the main focus of the testing activity in the project is not to meet the project schedule. But Its is a reality that a thorough and close monitoring of the Testing project is required to increase productivity, reduce cycle -time and improve quality.

...Psychological Testing PSY/475 Psychological Testing In this paper the subject is to summarize the major assumptions and fundamental questions associated with psychological testing. The author begins by defining the term test. Next, the author describes the major categories of tests and identifies the major uses and users of these tests. Last the paper compares and contrasts the concepts of reliability and validity and discusses how they affect the field of psychological testing. The Standards for Education and Psychological Testing defines test as, “An evaluative device or procedure in which a sample of an examinee’s behavior (is) evaluated and scored using a standardized process” (Hogan, 2007, pg. 38). Anastasi and Cronbach, both traditional textbook authors, define the term test as, “an objective and standardized measure of a sample of behavior” and “a systematic procedure for observing behavior and describing it with the aid of numerical scales or fixed categories” (Hogan, 2007, pg. 38). In psychology, tests are used to make important decisions about an individual. Testing samples a person’s behavior, creates a standardized measure, and contributes in making important decisions about the individual taking the test. Testing is used in many different areas and is used to sample a person behavior, create a standardize measure, and contribute in making important decisions. For example, college admissions officers consult test score before admitting or rejecting...

...Can Animals be used Animal Testing? Name: Institution: CAN ANIMALS BE USED IN ANIMAL TESTING? Thesis statement: This paper discusses research on how animal testing brings more medical advancement and less human-based experiments and sees if there are any alternatives to the use of animals in research since it is a practice of animal cruelty. Introduction Animal Testing refers to strategies done on living creatures for reasons of exploration into fundamental science and ailments, surveying the adequacy of new drugs, and examining the human health. The processes involved in this testing, even those that are seen to have no significant effect, still cause the animals bodily as well as mental pain and suffering. Often these processes cause a great deal of distress. Some animals are re-used in the succeeding experiments while others are killed at the end of the experiment. Approximately 115 million animals are estimated to be used every year in the world for laboratory experiments (Dawkins, 2012). However, only a few countries assemble and publish the data about the use of animal in testing and research. For instance, about 90 percent of the animals are used in laboratories in the United States. This statistics excludes species, for example, mice and birds, fish, reptiles and invertebrates, thus these figures presented by the U.S, Department of Agriculture is considerably underestimated. Countries in Europe such as France, United Kingdom, and Germany are among those using animals...

The first point has lead to competition between commercial and open source database vendors while the second has resulted in a need for high performance database systems. This whole controversy has in the past lead database vendors to employ numerous tricks in bid to improve the processing speed of their systems during benchmarking and thus falsely prove that their databases products are superior to other competitors. Some of their tricks include using high-speed CPUs and clusters, caching up data rows and storing SQL execution plans into RAM prior to testing thus bypassing disk I/O access and tremendously increasing performance (Burleson D, 2002).AS a result the author seeks to provide an independent third voice that will aid DBA in decision making. 1.

...Why Animal Testing should be Prohibited Alexandria McConnell 6/4/2015 ENG/130 Maureen Chisholm It is estimated that about 26 million animals are being used every year in the US for scientific and commercial research. They are used for many different things such as medical developments, the safety of products, and many other health care and cosmetic uses. While there are some laws in place that prevent the abuse of animals in these testing laboratories, many of these test subjects face cruel and inhumane treatment. There are alternative and equally effective ways to study and conduct research for such treatments, and although there have been proven benefits to some of the research conducted on these defenseless animals, the harsh effects of the experiments should not be overlooked or ignored. Animals are put through excruciating pain and usually given no anesthesia or relief during many of the test experiments performed in these laboratories. They are often forced to ingest and inhale deadly concoctions to study whether or not it would be safe for human consumption. It is also not uncommon for them to be deprived of food and water for prolonged periods of time. Animal test subjects are also being intentionally injured to study the healing process and the effects of pain and remedies of such, and sometimes purposely killed. A common test performed is the LD50, or lethal dose 50. This test involves giving animal large doses of chemicals to find out how much will kill...

...Animal Testing Introduction The application of animals to test a large number of products from household compounds and cosmetics to Pharmaceutical products has been considered to be a normal strategy for many years. Laboratory animals are generally used in three primary fields: biomedical research, product security evaluation and education. (Animal Experiments) It has been estimated that approximately, 20 million animals are being used for testing and are killed annually; about 15 million of them are used to test for medication and five million for other products. Reports have been generated to indicate that about 10 percent of these animals are not being administered with painkillers. The supporters of animal rights are pressurizing government agencies to inflict severe regulations on animal research. However, such emerging criticisms of painful experimentation on animals are coupled with an increasing concern over the cost it would have on the limitation of scientific progress. (Of Cures and Creatures Great and Small) Around the world, animals are utilized to test products ranging from shampoo to new cancer drugs. Each and every medication used by humans is first tested on the animals. Animals were also applied to develop anesthetics to ease human ailments and suffering during surgery. (Animal Experiments) Currently, questions have been raised about the ethics surround animal testing. As a result several regulations have been put in place to evaluate and control the...

...through torturous testing on a day to day basis that they cannot help, nor can they defend themselves. Since Ancient Greek times, animals have been undergoing cruel and inhumane medical testing that should not be done for the benefits of the human race. Animal testing is wrong because it is cruel, costly, harmful to animals, unreliable, and outdated. Animal testing has been around since the times of the Ancient Greeks. Between seventeen million and twenty-two million animals are used for biomedical research each year (Leepson). Many believe that animals do have rights, and there are many organizations out there to trying to ensure their safety and help them get out of the horrible treatments they endure. For example, the ASPCA, American Society for the Prevention of Cruelty to Animals, has been around since 1866 trying to curb the gruesome treatment of humans to animals. The ASPCA tries to prevent the abuse and neglecting of animals around the nation. They set up shelters for animals and they give vaccines and anything else they may need. The different types of animals being tested are endless; from mice to sheep, they all serve their own purpose in the medical field. Even though these animals have helped scientist break through some medical mysteries, it is still inhumane how they have to suffer in confined quarters. The CAFO, Concentrated Animal Feeding Operations, raise animals in small living spaces for their meet, food, and waste. Chickens, for example, are used for...

The report will conclude with an example of a penetration test. Operating Systems Dependency on Penetration Testing History and Purpose of Penetration Testing According to Pfleeger & Pfleeger 2011 in their book titled ‘Security in Computing’, penetration testing, or pentesting, is a technique used in computer security which an individual, or team of experts purposely tries to hack a computer system. Penetration started as a grey art that was often practiced in an unstructured and undisciplined manner by reformed or semi-reformed hackers. They used their own techniques and either their ‘home grown’ tools, or borrowed and traded ideas with associates. There was little reproducibility or consistency of results or reporting, and as a result the services were hard to integrate into...
