Cognitive-ergonomics and instructional aspects of e-learning courses

This paper presents an analysis of cognitive-ergonomic aspects of e-learning courses, offered by an organism from Brazilian Public Administration. The Cognitive Ergonomic studies conductive and cognitive aspects concerning to the relation between human, physics elements and social elements of the work space. From that usability aspects were evaluated by these points: i) visualization; ii) text comprehension lecture; iii) memory; iv) interface; v) instructional design; and vi) attention and learning. That survey is characterized as having been applied using the following techniques: (1) bibliographic survey, (2) field survey and (3) analysis of the documents. It was chosen the semi-structured questionnaire as the main method of data collection. About the interacting with artifacts, the interface of the courses is classified as direct engagement, because it allows the user to get the feeling that acts directly on the objects. Although the courses are well-structured they have flaws that will be discussed below. Even with these problems, the courses have a good degree of usability.     

Analysis of ergonomics conditions of a brand of mattress and pillows. University-industry project, Medellín-Colombia

This project presents an analysis of the ergonomic conditions of three types of mattress and three types of pillow. The products are manufactured by a Colombian company which specializes in flexible polyurethane foam and other products designed for rest and relaxation. The project was developed through the University - Industry relationship: a strategic partnership based on the knowledge and strengths of each component. The conceptual theories that underpin the Ergonomics Research Division of the Design Studies Research Group (GED) provided the methodological approach for the project: the characteristics, the requirements and the relationships that are established between the components that constitute the User - Product - Context system (basic principles of the Ergonomics - Design relationship). An important factor in the project was the conception and measurement of comfort. Comfort can be measured on an objective level (quantitative measurement), and on a subjective level (a user's particular perceptions and tastes). What constitutes 'comfort' can vary from person to person, thus making the identification of criteria for the standardization of consumer products problematic. This project enabled design recommendations to be made to the Company vis-à-vis future proposals for mattress and pillow products. This experience of applied research was carried out by professors and students from the Faculty of Industrial Design at the UPB in Medellín, Colombia.     

Preventive and curative importance of the baropodometric analysis for ergonomics and occupational health

The pressure distribution on the plantar surface may reveal information not only about the feet structure, also it may bring out information about the entire body posture not only on health but also pathologic conditions. The application in ergonomics and occupational health gives access to the postural correction that on a long term may provoke professional injuries giving presition and security. This study is on 132 workers of Universidad de las Américas.     

Immigration Policy in Australia,Canada, New Zealand,and the United States: An Overview of Recent Trends

Immigration policies in most host nations of the west have undergone significant changes in recent years. Based on the four country‐specific papers that appear in this section of the journal, and also on our own research, we present an overview of these changes and their context. In all countries, economic considerations play a central role in shaping immigration policy and greater importance is given to scientific research. Several common policy changes are noted in Australia, Canada and New Zealand which include: a shift away from a human capital focus toward more targeted selection based on labor market demand for specific skills, increased emphasis on temporary foreign worker programs, attraction of international students, an overhauling of the refugee system, and regionalization of immigration. In the U.S., while adoption of some of these changes has often surfaced in public policy and academic discussions, legalization of unauthorized migrants remains an important policy debate, with recent arguments focusing on the economic benefits of legalization.     

Poverty and gender perspective in productive projects for rural women in Mexico: impact evaluation of a pilot project

The objective of this study is to evaluate the impact of a pilot study that promoted productive and capacity-building activities among deprived rural women of Mexico. The evaluation design is observational; 1,278 women are interviewed, and the comparison group is estimated by propensity score matching. The results show a positive impact on the carrying out of agricultural activities, in the autonomy of women in decision making, as does their perception of their role in the household. However, the project does not decrease the number of hours set aside for household chores or improve the women's technical and administrative skills.     

Progress,democracy, efficiency: normative narratives in political science EU studies

ABSTRACT

This article identifies influential political narratives in the 73 currently most highly cited political science articles on the EU. It is based on systematic analysis of expressions of normativity, which signal that European integration, or its institutions or policies, are bad, good, flourishing or declining. A normative narrative of continuous progress in integration, connected with a 1990s grand theoretical debate in EU studies, accounts for much of the positive tone of EU studies until about 1998. Narratives about the EU's democratic deficit and its impact beyond its borders help explain the subsequent negative turn in EU studies normativity.     

Defining Susceptibility for Microbial Risk Assessment: Results of a Workshop

An interdisciplinary workshop was convened by the George Washington University in June 2001 to discuss how to incorporate new knowledge about susceptibility to microbial pathogens into risk assessment and management strategies. Experts from government, academic, and private sector organizations discussed definitions, methods, data needs, and issues related to susceptibility in microbial risk assessment. The participants agreed that modeling approaches need to account for the highly specific nature of host-pathogen relationships, and the wide variability of infectivity, immunity, disease transmission, and outcome rates within microbial species and strains. Concerns were raised about distinguishing between exposure and dose more clearly, interpreting experimental and outbreak data correctly, and using thresholds and possibly linearity at low doses. Recommendations were made to advance microbial risk assessment by defining specific terms and concepts more precisely, designing explicit conceptual frameworks to guide development of more complex models and data collection, addressing susceptibility in all steps of the model, measuring components of immunity to characterize susceptibility, reexamining underlying assumptions, applying default methods appropriately, obtaining more mechanistic data to improve default methods, and developing more biologically relevant and continuous risk estimators. The interrelated impacts of selecting specific subpopulations and health outcomes, and of increasing model complexity and data demands, were considered in the contexts of public policy goals and resources required. The participants stated that zero risk is unattainable, so targeted and effective risk reduction and communication strategies are essential not only to raise pubic awareness about water quality but also to protect the most susceptible members of the population.     

Workplace discrimination and missing limbs: the national EEOC ADA research project

Using the Integrated Mission System of the Equal Employment Opportunity Commission, the employment discrimination experience of Americans with missing limbs is documented. Researchers compare and contrast the key dimensions of workplace discrimination involving Americans with missing limbs and persons with back and other non-paralytic orthopedic impairments. Specifically, the researchers examine demographic characteristics of the charging parties; the industry designation, location, and size of employers against whom complaints are filed; the nature of discrimination (i.e., type of adverse action) alleged to occur; and the legal outcome or resolution of these complaints. Findings indicate that persons with missing limbs were more likely to encounter discrimination if they were male, under 20 or over 65 years of age, and White or Native American. They were also more likely to encounter more frequent discrimination when they worked for employers in the Southern United States, those with 200 or fewer employers, or whose industry designation involved manufacturing, construction, or transportation. Finally, the nature of job discrimination experienced by Americans with missing limbs is more likely to involve hiring, promotion, or job training than other issues. Implications for policy and advocacy are addressed.
