The Occupational Safety and Health Act Essay -- Workforce Safety Regul

The Occupational Safety and Health Act Just imagine working in an environment where there are very few safety regulations, and little safety equipment. Think of how it was for employees of a steel manufacturing plant to work where there are almost no safety regulations and safety hazards all around you. This is how the work environment was before 1970; there were only few laws or regulations that required employers to maintain certain safety standards or working conditions for employees. However in 1970 President Richard Nixon sought to change all of this by signing into law the Occupational Safety and Health Act (OSHA). The Occupational Safety and Health Act’s mission is to assure the safety and health of America's workers by setting and enforcing standards; providing training, and education; and encouraging continual improvement in workplace safety and health (OSHA.org). OSHA covers an extremely wide array of workers, from construction workers to office workers. However when the act was first passed it was not heavily enforced and lacked inspectors. In 1970 because there were three times as many fish and game wardens than there were OSHA inspectors, people said that the trout and quail were more protected than Americas working men and women (Bennett, Alexander, & Hartman, 2003). Though today OSHA has approximately 2100 inspectors, plus complaint discrimination investigators, engineers, physicians, educators, standards writers, and other technical and support pers...

The Rise of Hitler

The Nazi party first started after WWI when a group of unemployed German men. They were known as â€Å"The German Workers Party (GWP). † Adolf Hitler joined the group in 1919 and quick rose to a high ranking leader. His rise to the top of the GWP was due to his powerful speeches. Despite the ability of his speaking he often used it to promote national pride, militarism, and a racially â€Å"pure† Germany. After Hitler’s rise to leadership he changed the name to â€Å"The National Socialist German Workers’ which was referred to as â€Å"The Nazi Party†.Hitler tried to overthrow the government with the Nazi Party, but had no success. This leads up to his election as chancellor of Germany. While incarcerated, Hitler wrote a book called Mein Kampf, which established a foundation for the beliefs of the Nazi party. After its publication, Hitler could truly grow an army of supporters. According to the narrator’s of â€Å"World at War† After Hitler’s release he quickly pursued a political campaign for chancellor.This provided him with a chance to persuade more of the German public that they needed to condemn all Jews. He brought food and water to the poor, which help with the growth of The Nazi party and his supporters. According the text in â€Å"A Teachers Guide to The Holocaust† Hitler also began create subgroups for specific Germans such as, children, women, doctor’s, etc. Hitler’s attempt was also short lived because they lost the election.Years later after gaining more supports the Nazi Party prevailed and took over Germany due to Hindenburg’s new Government. This allowed Hitler to carry out his plan to rid the world of all Jewish people. In 1938 Germany started to ban Jews from most places. In 1942 the Germans decided it was time to take action start with their plan called â€Å"the final solution† which leads to the founding of concentration camps and the holocaust. The Germans quickly formed alliances with Italy, USSR, and Japan.Despite the alliance Japan created more problems for the Nazi party by attacking America without a declaration of war. After the attacks on Pearl Harbor America had officially joined the war against the Germans in WW2. America’s involvement created the Unfortunately Hitler’s ambition drove him to commit treason against Russia, which was Germany’s biggest ally at the time. Despite the Germany advantage of surprise they could not defeat the Soviets. America capitalized on Germany’s mistake by forming a brief alliance with Russia.

Neural Markers of Categorization

In 2006, University of Delaware’s Paul C. Quinn and Harvard Medical School’s Alissa Westerlund, and Charles A. Nelson study titled â€Å"Neural Markers of Categorization in 6-Month-Old Infants† was published in Psychological Science. The study was motivated by the lack of existing literature on neural markers in infants. These neural markers have been seen as critical in developing an underpinning concept-formation in infants which in turn influences perception and cognitive development. Despite the importance of the neural markers of categorization to various fields of study, there is limited existing literature about it. Furthermore, existing literatures have not yet determined the neural markers and conditional determinants that can be associated with category formation. Most studies on infants have focused on the use of novel stimuli or the use of behavioral indicators to indicate categorization or concept formation. Study Objectives The main objective of the study was to identify neural activity involved in concept-formation in infants. By analyzing learning a category during familiarization, behavioral performance preference for a novel category global-level category learning, neural determinants will be identified. This will then enhance existing methodologies and research regarding concept formation, in particular, category-learning processes in infants. In doing so, the study will be able to not only further knowledge in neural markers and development but also serve as a means to verify conclusions regarding the topic determined outside of neural indicators (Quinn et al 58). Furthermore, the study is to serve as a foundation for further studies focusing on infant development and learning. Methodology Ten infants were included in the study that was selected from an original group of twenty one. Criteria for inclusion included were the child’s ability to stay focused on the stimuli and behavior. The mean age of participants was 198.8 days and 70% of the selected participant were female (60). The stimuli used for testing were colored photos featuring various breeds of cats and dogs assuming different postures. Luminosity of the photographs was based from analysis of the pictures using Adobe Photoshop: luminosity of the pictures ranged from 225.54 to 248.42 for pictures depicting dogs, for cats 226.05 to 249.57. Shape values ranged from 20.03 to 56.88 for cats and 24.28 to 61.65 for dogs. While the area and perimeter of the pictures was based on LASICO 1281 Area/Line Meter. Testing procedures included event-related potential (ERP) Testing, ERP Waveform Analysis and Behavioral Testing. ERP Testing was conducted in an acoustically shielded and light-controlled room. The infants sat with a respective parent in front of a monitor measuring 48 centimeters across and 31 centimeters tall. The infants viewed the pictures randomly from a distance of 60 centimeters with each picture being flashed for 500 ms. Adjustments were made based on observations on the child through video monitors. The results were then recorded and amplified onto a vertex reference at 0.1- to 100-Hz band-pass filtering and digitized at 250-Hz. Electroencephalographic data was handled through NetStation 4.0.1. Adjustments were made as baseline correction to 100-ms prestimulus recording interval. Final phase of testing was done to determine behavioral evidences for category learning. Two 5-s test trials during which a novel cat was paired with a novel dog in a left-right arrangement with two independent observers, both blind to the lateral position of the animals shown to the infant. Results The study concluded that infants, in the processes of learning a category, exhibited higher negative amplitude on left occipital-parietal scalp in response indicating initial experience with category exemplars with the first cat pictures 1 to 18 and novel dogs. Furthermore, comparisons of average amplitude of ERP signals between 1,000 and 1,500 ms after each picture was shown did not vary in cats 1 to 18. this indicates that neural instantiation of are key behavioral indicants of categorization implying that the infants respond to the novel as something familiar. With regards to novel categories, the results indicated the infants’ preference for such (61). This was indicated by the infants’ response to the novel dogs: negative amplitude over left-central became more pronounced. The implications is that Nc component or negative central component of the ERP  waveform can be e a neural marker of infants’ novel-category preference. Behavioral Performance tests from the looking-time data recorded when paired-preference was conducted indicated the infants’ preference for the novel dog versus the novel cat. The infants also showed novel-category preference by 62.52%. Since this value exceeds probability thresholds which in the study are divided equally between cats and dogs, the researchers are confident in concluding that the infants learned category representation for cats that included novel cats without the exclusion of the dogs. The results also yielded conclusions regarding global-level category learning. The researches believe that global-coding nodes are quickly learned as a means to represent or map large differences when there are a limited number of attributes that distinguished the global level Significance and Implications The discrimination of entities categorically is believed to have its roots during development. Therefore, determining the mechanism of category representations develop together with knowledge structures, vocabulary development and expressions that influence cognition, thus, the importance of measuring infants’ visual timing and recognition when presented with both realistic and abstract figures. This will allow for insights to not only in visual and cognitive development but also provide critical information in the overall development mapping of an individual (59). However, since there are no previous studies existing to evaluate the conclusions of the study to, the determination made by the paper will need further research, a constraint that the researchers themselves recognized (61). Despite this constraint, the study was able to provided significant evidence using neural markers using ERP and brain wave mapping that infants learning a category through the process of familiarization have a preference for novel category and respond to category exemplars at multiple levels of inclusiveness. Therefore, neural architecture required for object categorization processes is present in infants aged six months and below which in turn is giving greater insight to the neurological developments critical to learning and development.
