Ergonomic work analysis as a tool of prevention for the occupational safety and health management system

This paper introduces the Ergonomic Work Analysis as a relevant instrument to identify the risks in occupational environments through the investigation of factors that influence the relationship between the worker and the productive process. It draws a parallel between the several aspects of risk identification in traditional tools of Health and Safety Management and the factors embraced by the Ergonomic Work Analysis, showing that the ergonomic methodology is able to go deeper in the scenarios of possible incident causes. This deepening enables the establishment of a relationship between the work context and the upcoming damage to the physical integrity of the worker. It acts as a complementary instrument in the traditional approach to the risk management. In order to explain the application of this methodology in a preventive way, it is presented a case study of a coal mill inspector in a siderurgic company.     

The Nagorno Karabakh Conflict through the Prism of the Image of the Enemy

The post-Soviet space is fraught with multiple problems, risks and threats caused by unresolved conflicts. The vast majority of these conflicts possess a strong ethno-political component that complicates all the conflict resolution attempts: neglect of the role of ethnicity in interstate and intrastate conflicts can lead to overt conflict on the one hand and a deadlocked situation in respect to all mediation on the other hand. This article focuses upon the role and impact of ethnicity factor and the ways in which it is exploited and manipulated. The Nagorno Karabakh conflict serves as the major empirical case.     

Economic,Financial and Geopolitical Governance: USA,European Union and China

The paper examines the policies, choices, structural reforms, regulatory rules, corporate and public administration matching the world standards, openness, innovation, competitiveness, fulfillment of multilateral obligations, integration and regional approach achievements and international relations conditionality in the “Global Governance and Geopolitics” of the main economic, financial and policy issues, with special focus on the new regional approaches pursued by America, the European Union and Asia and the role of the emerging and transition countries. After the US Dollar, now the Eurozone is under pressure and the main Asian countries fear a contagion effect. While somebody proposes a slow devaluation of the Euro in order to soften the public deficits of the group of most exposed countries and restore more competitiveness to the real economy, political leaders are thinking to adopt indirectly the Euro two speeds operative monetary strategy, through the introduction of the majority vote, instead of the full Members consensus, for the most important decisions at the ECB in Frankfurt. Aside these monetary and institutional measures, the binding of the single national fiscal policy to more strict EU parameters of compatibility with the Eurozone sustainability appear unavoidable. This paper represents the background of my lecture given on November 4 at the Beijing Forum 2011 “The Harmony of Civilizations and Prosperity for All: Tradition and Modernity, Transition and Transformation” () at the PEK University.     

Choice of study discipline and the postponement of motherhood in Europe: The impact of expected earnings,gender composition,and family attitudes

Theory suggests that the field of study may be at least as consequential for fertility behavior as the duration and level of education. Yet, this qualitative dimension of educational achievement has been largely neglected in demographic studies. This article analyzes the mechanisms relating the field of study with the postponement of motherhood by European college-graduate women aged 20–40. The second round of the European Social Survey is used to assess the impact of four features of study disciplines that are identified as key to reproductive decision making: the expected starting wage, the steepness of the earning profile, attitudes toward gendered family roles, and gender composition. The results indicate that the postponement of motherhood is relatively limited among graduates from study disciplines in which stereotypical attitudes about family roles prevail and in which a large share of the graduates are female. Both the level of the starting wage and the steepness of the earning profile are found to be associated with greater postponement. These results are robust to controlling for the partnership situation and the age at entry into the labor market.     

Early life exposures and the occurrence and timing of heart disease among the older adult Puerto Rican population

Few studies have examined the effects of early life conditions on the timing of the onset of heart disease. We use the remarkable example of a representative sample of the population of older Puerto Ricans aged 60– 74 who lived in the countryside during childhood (n = 1,438) to examine the effects of seasonal exposures to poor nutrition and infectious diseases during late gestation on the timing of the onset and the probability of ever experiencing adult heart disease. Cox and log logistic hazard models controlling for childhood conditions (self-reported childhood health status and socioeconomic status [SES], rheumatic fever, and knee height) and adult risk factors (adult SES, obesity, smoking, texercise, and self-reported diabetes) showed that the risk of onset of heart disease was 65% higher among those born during high-exposure periods compared with unexposed individuals. However, there were no significant differences in median time of onset for those ever experiencing heart disease. As a comparison, we found that there were no significant seasonality effects for those who lived in urban areas during childhood. We conclude that early exposures in utero have important ramifications for adult heart disease among the older Puerto Rican population. We show, however, that while exposure is associated with the probability of ever experiencing adult heart disease, it is not associated with the timing of onset among those who do experience it.     

Health,wartime stress,and unit cohesion: Evidence from Union Army veterans

We find that Union Army veterans of the American Civil War who faced greater wartime stress (as measured by higher battlefield mortality rates) experienced higher mortality rates at older ages, but that men who were from more cohesive companies were statistically significantly less likely to be affected by wartime stress. Our results hold for overall mortality, mortality from ischemic heart disease and stroke, and new diagnoses of arteriosclerosis. Our findings represent one of the first long-run health follow-ups of the interaction between stress and social networks in a human population in which both stress and social networks are arguably exogenous.     

Knox meets Cox: Adapting epidemiological space-time statistics to demographic studies

Many important questions and theories in demography focus on changes over time, and on how those changes differ over geographic and social space. Space-time analysis has always been important in studying fertility transitions, for example. However, demographers have seldom used formal statistical methods to describe and analyze time series of maps. One formal method, used widely in epidemiology, criminology, and public health, is Knox’s space-time interaction test. In this article, we discuss the potential of the Knox test in demographic research and note some possible pitfalls. We demonstrate how to use familiar proportional hazards models to adapt the Knox test for demographic applications. These adaptations allow for nonrepeatable events and for the incorporation of structural variables that change in space and time. We apply the modified test to data on the onset of fertility decline in Brazil over 1960–2000 and show how the modified method can produce maps indicating where and when diffusion effects seem strongest, net of covariate effects.     

Cultural Activities,Identities, and Mental Health Among Urban American Indians with Mixed Racial/Ethnic Ancestries

Focus groups were conducted to appreciate the voices of Urban American Indians (UAI) who have mixed ancestries residing in Philadelphia, Pennsylvania. Participants (15 women and 10 men, 19–83 years of age) with a variety of Native ancestries coming from different nations (i.e., blackfeet, blackminkwa, Cherokee, Creek, Delaware, Lakota, Powhatan, Seminole, and Shawnee) reported to also have a Non-Native racial/ethnic ancestry such as African/black, Hispanic, and/or Caucasian/white. Specifically, this study provided evidence about (a) the complexity and challenge of being “mixed” UAI (e.g., “living a culture” as opposed to blood quantum in determining a personal identity) (b) the linkage of cultural identities to mental health (c) contributions of cultural activities to identities and mental health (e.g., therapeutic and healing functions of cultural activities), and (d) very limited urban Native-oriented mental health service (e.g., visions for Native American-centered mental health clinic in an urban setting). Building on those UAI’s voices, this paper provides a context for the need of a culturally respectful transformation of urban mental health system by highlighting the clinical significance of cultural identity and mental health promotion for UAI.     

Racial and Ethnic Differentials in Idleness,Highest-Risk Idleness,and Dropping Out of High School

This research investigates three different indicators of at-risk socio-demographic conditions including dropping out of high school, being idle, and being in highest-risk idleness among non-immigrant persons aged 19–24. Using data from the 2000 US Census, our results detail the differentials in these characteristics for 30 different racial/ethnic groups that are further broken down by gender. The findings indicate a wide range in the prevalence of these at-risk socio-demographic conditions. Groups that tend to be the most at-risk in terms of these indicators include African Americans, Cambodians, Laotians, Native Americans, other Hispanic whites, and white Mexicans. With the exception of the other Pacific Islander and Thai, young women have lower high school dropout rates than do young men. However, young women are substantially more likely than young men to be idle which we define as not being in school, the labor force, or the military. After defining highest-risk idleness as never-married persons without children who are idle, however, the rates are slightly lower for young women than for young men.     

How Does the Age Gap Between Partners Affect Their Survival?

I use hazard regression methods to examine how the age difference between spouses affects their survival. In many countries, the age difference between spouses at marriage has remained relatively stable for several decades. In Denmark, men are, on average, about three years older than the women they marry. Previous studies of the age gap between spouses with respect to mortality found that having a younger spouse is beneficial, while having an older spouse is detrimental for one’s own survival. Most of the observed effects could not be explained satisfactorily until now, mainly because of methodological drawbacks and insufficiency of the data. The most common explanations refer to selection effects, caregiving in later life, and some positive psychological and sociological effects of having a younger spouse. The present study extends earlier work by using longitudinal Danish register data that include the entire history of key demographic events of the whole population from 1990 onward. Controlling for confounding factors such as education and wealth, results suggest that having a younger spouse is beneficial for men but detrimental for women, while having an older spouse is detrimental for both sexes.
