Johann Peter Süssmilch: A German Prophet in Foreign Countries

The clergyman Johann Peter Süssmilch (1707–1767), chaplain to King Frederick II of Prussia, deserves to be called the father of German demography and was recognized as such in his own lifetime in his country of origin and throughout Europe, except possibly in France and Italy. In his Göttliche Ordnung (1741 and 1761–2), he attempted to explain the regularity of vital phenomena as being due to divine intervention. His conception of a ‘divine’ order soon gave way to that of a ‘natural’ order. His life tables, though incorrect, continued to be used by insurance offices well into the nineteenth century. His views about the relationships between mortality on one hand, and fertility and nuptiality on the other led to controversies between Malthus, Sadler and other scholars. Later, his ideas were given a broader economic and social interpretation. Whether as the last representative of ‘primitive’ demography, or the first scientific scholar of the subject, he contributed to the triumph of political arithmetic throughout Europe.     

Ethnic Labels and Ethnic Identity as Predictors of Drug Use among Middle School Students in the Southwest

This article explores differences in the self‐reported drug use and exposure to drugs of an ethnically diverse group of 408 seventh‐grade students from a large city in the southwest. We contrast the explanatory power of ethnic labels (African American, non‐Hispanic White, Mexican American, and mixed ethnicity) and two dimensions of ethnic identity in predicting drug use. One dimension focuses on perceived ethnically consistent behavior, speech, and looks, while the other gauges a sense of ethnic pride. Ethnic labels were found to be somewhat useful in identifying differences in drug use, but the two ethnic identity measures, by themselves, did not generally help to explain differences in drug use. In conjunction, however, ethnic labels and ethnic identity measures explained far more of the differences in drug use than either did alone. The findings indicate that the two dimensions of ethnic identity predict drug outcomes in opposite ways, and these relations are different for minority students and non‐Hispanic White students. Generally, African American, Mexican American, and mixed‐ethnicity students with a strong sense of ethnic pride reported less drug use and exposure, while ethnically proud White students reported more. Ethnic minority students who viewed their behavior, speech, and looks as consistent with their ethnic group reported more drug use and exposure, while their White counterparts reported less. These findings are discussed, and recommendations for future research are provided.     

The journalist as the audience: Evaluating the U.S. Navy’s “Sailor for a Day” campaign

This study demonstrates how focusing on the journalist as the audience of a media relations campaign can result in significant positive media coverage. Specifically, we examined the U.S. Navy’s “Sailor for a Day” campaign that invited media to experience a day in the life of a U.S. Navy sailor aboard an aircraft carrier. We propose that the “Sailor for a Day” campaign successfully influenced journalist perceptions and media coverage because 1) the pitch tied to programming needs; 2) uncommon access was granted; and 3) the journalist experience was a prominent feature of the media pitch.     

Family risk and resiliency factors, substance use, and the drug resistance process in adolescence

Recent approaches to drug prevention have emphasized risk and resiliency factors. Two models have been developed to explain these factors, one which posits that separate elements make up each set and the other which posits that a single factor can be either a risk or a resiliency factor depending on, for example, if it is present (resiliency) or absent (risk). This study tested these models and attempted to compare the effects of risk and resiliency across gender and ethnicity. Results support the model in which risk and resiliency are discrete sets of factors and demonstrate that overall resiliency factors play a larger role than risk factors in substance use and drug resistance processes. However, gender proved to be an important moderator of these effects. For adolescent males, resiliency has an indirect effect on overall substance use through age of first use, while risk has a direct effect on overall substance use. For adolescent females, resiliency has a direct effect on overall substance use and risk has an indirect effect through age of first use. This indicates that while early interventions are important for both genders, resiliency factors must be dealt with before initiation of substance use for males. Findings did not differ substantially across ethnicity, although the small African-American sample size may have limited power to detect differences.     

Role Conflict and Role Overload: Different Concepts, Different Consequences

The concepts of role conflict and role overload have been used, often interchangeably, to interpret sources of gender differences in role-related mental health among men and women who combine the roles of spouse, parent, and worker. However, these types of chronic role strains actually represent two distinct concepts. Definitions of the concepts suggest different contextual sources for these role difficulties as well as different mental health consequences of experiencing them. This paper analyzes some potential sources of feelings of role conflict and role overload, and estimates their effects in undermining psychological well-being among a sample of women who combine work and family roles. Results indicate that (a) different contextual factors influence individuals'feelings of role conflict and role overload, and (b) feelings of role conflict significantly undermine psychological well-being, while feelings of role overload do not.     

Exposure of Contractors to Chemical Pollutants During the Maintenance Shut-Down of a Chemical Plant

The exposure of employees of different contracting firms to chemical pollutants was assessed during the five-week biennial maintenance shut-down of an isocyanate (TDI) synthesis plant. This assessment was mainly based on personal sampling, but work-related constraints occasionally required that area samples be used instead. Many tasks were carried out during the shut-down procedure (dismantling of reactors, installation of insulation, refection of kilns, cleaning, painting, electricity, etc.), thereby causing the employees of the contracting firms to be exposed to different kinds of pollutants, including products used or manufactured in the process (solvents, TDI and its synthesis intermediates), and products specific to the contractors' activity (welding fumes, crystalline silica, mineral fibers of heat insulation). The highest level of exposure (mainly to TDI) was found for the mechanical engineering activities undertaken during the dismantling of reactors and for cleaning activities. It was demonstrated that there was much variability in day-to-day exposure levels, and occasionally in the exposure levels encountered during a given shift. Cases of concomitant exposure to TDI (mainly short-term exposures) and other pollutants due to simultaneous activities from different tasks in the same area (co-activity) were also observed. Both the need for, and limitations of personal protective equipment (mainly respiratory) are stressed. Special emphasis is put on the responsibility of the owner of the facilities in helping the contractors in the organization of a health and safety policy.
