Social network resources and management of hypertension

Hypertension is one of the most prevalent chronic diseases among older adults, but rates of blood pressure control are low. In this article, we explore the role of social network ties and network-based resources (e.g., information and support) in hypertension diagnosis and management. We use data from the National Social Life, Health, and Aging Project to identify older adults with undiagnosed or uncontrolled hypertension. We find that network characteristics and emotional support are associated with hypertension diagnosis and control. Importantly, the risks of undiagnosed and uncontrolled hypertension are lower among those with larger social networks-if they discuss health issues with their network members. When these lines of communication are closed, network size is associated with greater risk for undiagnosed and uncontrolled hypertension. Health care utilization partially mediates associations with diagnosis, but the benefits of network resources for hypertension control do not seem to stem from health-related behaviors.     

Women’s status and carbon dioxide emissions: A quantitative cross-national analysis

Global climate change is one of the most severe problems facing societies around the world. Very few assessments of the social forces that influence greenhouse gas emissions have examined gender inequality. Empirical research suggests that women are more likely than men to support environmental protection. Various strands of feminist theory suggest that this is due to women’s traditional roles as caregivers, subsistence food producers, water and fuelwood collectors, and reproducers of human life. Other theorists argue that women’s status and environmental protection are linked because the exploitation of women and the exploitation of nature are interconnected processes. For these theoretical and empirical reasons, we hypothesize that in societies with greater gender equality there will be relatively lower impacts on the environment, controlling for other factors. We test this hypothesis using quantitative analysis of cross-national data, focusing on the connection between women’s political status and CO₂ emissions per capita. We find that CO₂ emissions per capita are lower in nations where women have higher political status, controlling for GDP per capita, urbanization, industrialization, militarization, world-system position, foreign direct investment, the age dependency ratio, and level of democracy. This finding suggests that efforts to improve gender equality around the world may work synergistically with efforts to curtail global climate change and environmental degradation more generally.     

An Effective Statistical Approach for Comparative Risk Assessment1

Comparative risk assessment is an evaluation process designed to rank environmental problems based on the severity of potential hazards. The purpose of this paper is to provide an effective statistical approach to analyze perceived environmental risks. Environmental problems, evaluative criteria, and other potential moderator variables need to be determined first, and then the risk perception data collected. Repeated measures analysis is used to first test for interactions between environmental problems and potential moderator variables. If there are no significant interactions, then the risk difference among environmental problems is tested unconditionally; otherwise the risk difference is tested conditionally. Cluster analysis for environmental problems is performed only when the risk difference is significant. The clustering results can be objectively determined by using the simultaneous T² confidence intervals. Risk-based priority setting is made according to the clusters obtained. To illustrate this approach, an empirical study of comparative socioeconomic risks in Taiwan was conducted. Socioeconomic impacts areas including social security, quality of life, production cost, investment willingness, and economic resources are used as evaluative criteria. Results indicate that selected impact areas do affect relative risk differences among 24 environmental problems, and the difference is significant for each area. Therefore, cluster analysis is conducted separately for each impact area. Risk-based priority settings for clusters of environmental problems are reported.     

Approaches to the study of gender in marriage and family therapy curricula

This study compares two accredited marriage and family therapy programs: One includes a separate course on gender, and the other integrates gender throughout the curriculum. Students from the two programs rated their own and their peers' experience of how gender education effects therapy, program culture, and personal life. Results indicate that students from the integrated program view their peers as incorporating gender ideas in therapy to a significantly greater extent (t = 2.83, p < .05) than do students in the gender course program. However, students from the program that has a gender course leaned more toward agreement with feminist concepts than did students from the integrated program. Overall, students appear to be learning about gender and integrating these concepts into their work as therapists. Discussion is included on how to choose a gender curriculum.     

Land fragmentation under rapid urbanization: A cross-site analysis of Southwestern cities

Explosive population growth and increasing demand for rural homes and lifestyles fueled exurbanization and urbanization in the western USA over the past decades. Using National Land Cover Data we analyzed land fragmentation trends from 1992 to 2001 in five southwestern cities associated with Long Term Ecological Research (LTER) sites. We observed two general fragmentation trends: expansion of the urbanized area leading to fragmentation in the exurban and peri-urban regions and decreased fragmentation associated with infill in the previously developed urban areas. We identified three fragmentation patterns, riparian, polycentric, and monocentric, that reflect the recent western experience with growth and urbanization. From the literature and local expert opinion, we identified five relevant drivers ?C water provisioning, population dynamics, transportation, topography, and institutions ?C that shape land use decision-making and fragmentation in the southwest. In order to assess the relative importance of each driver on urbanization, we linked historical site-specific driver information obtained through literature reviews and archival analyses to the observed fragmentation patterns. Our work highlights the importance of understanding land use decision-making drivers in concert and throughout time, as historic decisions leave legacies on landscapes that continue to affect land form and function, a process often forgotten in a region and era of blinding change.     

THE GLOBALIZATION OF ENVIRONMENTAL CONCERN AND THE LIMITS OF THE POSTMATERIALIST VALUES EXPLANATION: Evidence from Four Multinational Surveys

Conventional wisdom has long held that widespread citizen concern for environmental quality is limited to wealthy nations. Both academics and policymakers assume that residents of poor nations are too preoccupied with satisfying their "material" needs to support the "postmaterialist" value of environmental protection. This view was challenged by results of Gallup's 24-nation "Health of the Planet" (HOP) survey conducted in 1992, as the HOP found highly inconsistent and often negative correlations between national affluence and environmental concern. The current article compares results from three waves of the "World Values Survey" (WVS) to those of the HOP. When appropriate measures of environmental concern are employed, the WVS results generally replicate those of the HOP, as in all three waves such concern correlates inconsistently with national affluence. The overall results suggest that citizen concern for the environment is not dependent on national affluence, nor on affluence-based postmaterialist values.     

MARXISM, POSITIVISM, AND SCIENTIFIC SOCIOLOGY: Social Gravity and Historicity

Marxism and positivism are often thought to be incompatible perspectives in sociology. Yet, Marxism has a long history of commitment to scientific inquiry. Here, we juxtapose these two scientific paradigms—Marxism and positivism—in ways that can enhance both, while highlighting in particular the power of the former. We argue that many of the key theoretical claims of Marxism can be explored in terms of analytic concepts congruent with and easily accessible to the contemporary positivist tradition. Marxist criticisms of the cruder versions of the positivist program are not antiscience but are rather rational critiques based on scientific principles.     

Structural Influences on Energy Production in South and East Asia, 1971–20021

To address questions about the environmental consequences of globalization and modernization, I estimate the effects of a variety of structural factors on energy production in 14 nations of South and East Asia, which contain more than half the world’s population, using panel data covering the period 1971–2002. My results suggest that energy production is significantly influenced by a variety of structural factors, including economic development, urbanization, export intensity, and debt service. Consistent with the arguments of theorists of the political economy of the world‐system, I find compelling evidence that modernization and integration into the global economy contribute to natural resource exploitation.     

Office of the future — New challenges for operational research

A technological barrage has been fired on the office environment in an attempt to attack rising costs and improve productivity. Although very new, a dramatic level of effort is already being applied. The state of the art is changing daily but so far the problems still outnumber the solutions. The opportunities to contribute are significant. This paper briefly describes the scene, characterizes the state-of-the-art and suggests an entry strategy for the OR professional. The probable response of the OR profession is considered.
