Career patterns of U.S. male academic social scientists

Seventy-four U.S. male academic social scientists provided career stage data. All were born between 1893 and 1903. The subjects were divided into four groups on the basis of their scholarly article productivity after age 59. Spilerman's conceptualization of work history guided the analysis. To a lesser extent, adult development theory (e.g., Hall and Nougaim, 1968) was also examined.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42843/1/10734_2004_Article_BF00139794.pd

Vegetation type is an important predictor of the arctic summer land surface energy budget

Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate interactions in the rapidly changing Arctic, uncertainties in their prediction persist. Here, we harmonize SEB observations across a network of vegetated and glaciated sites at circumpolar scale (1994-2021). Our variance-partitioning analysis identifies vegetation type as an important predictor for SEB-components during Arctic summer (June-August), compared to other SEB-drivers including climate, latitude and permafrost characteristics. Differences among vegetation types can be of similar magnitude as between vegetation and glacier surfaces and are especially high for summer sensible and latent heat fluxes. The timing of SEB-flux summer-regimes (when daily mean values exceed 0 Wm(-2)) relative to snow-free and -onset dates varies substantially depending on vegetation type, implying vegetation controls on snow-cover and SEB-flux seasonality. Our results indicate complex shifts in surface energy fluxes with land-cover transitions and a lengthening summer season, and highlight the potential for improving future Earth system models via a refined representation of Arctic vegetation types.An international team of researchers finds high potential for improving climate projections by a more comprehensive treatment of largely ignored Arctic vegetation types, underscoring the importance of Arctic energy exchange measuring stations.Peer reviewe

Protein 3D Structure Computed from Evolutionary Sequence Variation

The evolutionary trajectory of a protein through sequence space is constrained by its function. Collections of sequence homologs record the outcomes of millions of evolutionary experiments in which the protein evolves according to these constraints. Deciphering the evolutionary record held in these sequences and exploiting it for predictive and engineering purposes presents a formidable challenge. The potential benefit of solving this challenge is amplified by the advent of inexpensive high-throughput genomic sequencing

What Makes Retirees Happier: A Gradual or 'Cold Turkey' Retirement?

This study explores the factors that affect an individual’s happiness while transitioning into retirement. Recent studies highlight gradual retirement as an attractive option to older workers as they approach full retirement. However, it is not clear whether phasing or cold turkey makes for a happier retirement. Using longitudinal data from the Health and Retirement Study, this study explores what shapes the change in happiness between the last wave of full employment and the first wave of full retirement. Results suggest that what really matters is not the type of transition (gradual retirement or cold turkey), but whether people perceive the transition as chosen or forced

On the Role of Faith in Sustainability Management: A Conceptual Model and Research Agenda

International audienceThe objective of this article is to develop a faith development perspective on corporate sustainability. A firm’s management of sustainability is arguably determined by the way decision-makers relate to the other and the natural environment, and this relationship is fundamentally shaped by faith. This study advances theoretical understanding of the approach managers take on sustainability issues by explaining how four distinct phases of faith development—improvidence, obedience, irreverence and providence—determine a manager’s disposition towards sustainability. Combining insights from intentional and relational faith development theories, the analysis reveals that a manager’s faith disposition can be measured according to four interrelated process criteria: (1) connectivity as a measure of a manager’s actual engagement and activities aimed at relating to sustainability; (2) inclusivity as a measure of who and what is included or excluded in a manager’s moral consideration; (3) emotional affinity as a measure of a manager’s sensitivity and affection towards the well-being of others and ecological welfare; and (4) reciprocity as a measure of the degree to which a manager is rewarded for responding to the needs and concerns of ‘Others’, mainly in the form of a positive emotional (and relational) stimulus. The conceptual model consolidates earlier scholarly works on the psychological drivers of sustainability management by illuminating our search for a process of faith development that connects with an increasingly complex understanding of the role of business in society

Ohio Longitudinal Study on Aging and Retirement, 1975-1995

The Ohio Longitudinal Study on Aging and Retirement was begun in 1975 to investigate certain aspects of the retirement process and their impact on the physical aging and the social adjustment of individuals. In 1975, Miami University's Scripps Foundation Gerontology Center launched a study of all adults who were age 50 or over living in Oxford Township, Ohio. More than 1,500 individuals were mailed a 42-item, self-administered questionnaire, consisting mainly of precoded items. Over 1,100 individuals returned questionnaires, 1,106 of which were usable. The questionnaire tapped issues of retirement, leisure activities, life satisfaction, as well as basic demographic information such as age, employment status and history, marital status, etc. Follow-up questionnaires were mailed to participants in 1977, 1979, 1981, 1991, and 1995. Follow-up questionnaires were designed to assess changes in the respondents' lives and their subsequent effects. The 1977 and 1979 questionnaires essentially replicated the 1975 questionnaire. After the third wave, research objectives included factors involved in adjustment to retirement over time, adjustment to widowhood, intergenerational contact, and adjustment to physical limitations due to disability. The Murray Research Archive holds numeric data files from the 1975, 1977, 1979, 1981, 1991, and 1995 waves of data collection
