Differences between a persons head size and their intelligence Assignment

Differences between a persons head size and their intelligence - Assignment Example The researcher states that one of the primary assertions of Broca’s research is that ‘eminent’ men have significantly greater brain size than their ‘mediocre’ counterparts. The elucidation of the claim with data on Bostonian criminals from differing vocations articulated Broca’s argument that a person’s intelligence had a direct relation to the person’s brain size. Data on brain sizes with factorial categorizations on vocational backgrounds of the persons under study gave the impression that brain size and intelligence bear a relationship. The observation stirred considerable interest among researchers, who sought to establish how the human intelligence researchers had successfully pushed the possibility to the periphery in favor of intelligence tests. However, statistical tools, and in particular one-way ANOVA, which is a handy statistical tool for comparison of means and determining interrelations between data values, the data m ight lead to a different conclusion. Through tentative statistical analysis on the data purporting to illustrate Broca’s claim of brain correlation to intelligence, a number of importance issues come to notice. Firstly, what the researcher labels as standard deviation is in fact standard error, which are two different terms, and have differing impacts on the test of hypothesis for Broca’s argument. Secondly, it becomes apparent that there was omission of some groups from the final data, which may completely reverse the findings of the study. (Gould, 1981). Finally, the listing of the data items suggests suspicious agenda, as it might very well lead a statistical analysis to lead to the acceptance of a contrary

The Safety of Recovery Personnel and Rescue Workers Essay

The Safety of Recovery Personnel and Rescue Workers - Essay Example Such feedbacks must be forwarded and processed by the appropriate supervisors and personnel who are in charge of monitoring end results (SLAC 2009). A worksite analysis must be done and should be the preliminary step in determining what jobs and workstations are the impending sources of the problems. In the worksite analysis, exposures, problem tasks, and risks are evaluated and identified (Herman et al 1998). A valuable worksite analysis is comprised of all the jobs and work activities needed in the whole operation. As an industrial hygienist, I would personally recommend adequate inspection, research, and examination on how a certain physical or chemical hazard at the job site can affect the workers’ health before actually letting them enter the work zone; since this is part and parcel of the worksite analysis phase. The result of which will be given appropriate remedial or corrective action (Herman et al 1998). The recognition and control of hazards is relative to the utilization of environmental monitoring and methodical appraisal of hazards in order to detect the range of risks they pose that pertains to the employment of engineering and work practice controls along with other methods to contain any potential hazards, which workers may be exposed to (Herman et al 1998). The appraisal and identification of work hazards including traumas and tensions which are grounds for sickness, impaired health and creates a certain degree of discomfort to workers by way of having contact with chemicals, physical, ergonomic and biological factors is done essentially to recognize said potential conditions and eradicate or manage them through the application of any suitable corrective measures (Herman et al 1998). To decrease the adverse health hazards which employees or workers are exposed to, engineering controls must be modified and put into operation.
