Full text linkPerceived work ability refers to a worker's assessment of his or her ability to continue working in his or her job, given characteristics of the job along with his or her resources. Perceived work ability is a critical variable to study in the United States, given an aging workforce, trends to delay retirement, and U.S. policy considerations to delay the age at which full Social Security retirement benefits may be obtained. Based on the job demands-resources model, cognitive appraisal theory of stress, and push/pull factors related to retirement, we proposed and tested a conceptual model of antecedents and outcomes of perceived work ability using 3 independent samples of U.S. working adults. Data regarding workers' job characteristics were from self-report and Occupational Information Network measures. Results from relative importance analysis indicated that health and sense of control were consistently and most strongly related to work ability perceptions relative to other job demands and job and personal resources when perceived work ability was measured concurrently or 2 weeks later in samples with varying occupations. Job demands (along with health and sense of control) were most strongly related to work ability perceptions when perceived work ability was measured in a manufacturing worker sample 1.6 years later. Perceived work ability also predicted lagged labor force outcomes (absence, retirement, and disability leave) while controlling for other known predictors of each. Consistent indirect effects were observed from health status and sense of control to all 3 of these outcomes via perceived work ability.CDC-NIOSH 254-2010-M-37002/PHS HHS/United StatesP30 AG012846/AG/NIA NIH HHS/United StatesP30 AG12846/AG/NIA NIH HHS/United StatesR01 OH OH008929/OH/NIOSH CDC HHS/United StatesU01 AG009740/AG/NIA NIH HHS/United State
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Examining the Influence of Intolerance of Uncertainty on (Occupational) Future Time Perspective and Retirement-Related Outcomes in Working Adults
No full textUncertainty regulation models have recently challenged the assumption that uncertainty is inherently negative, describing ways that uncertainty regulation can lead to effectiveness. The goal of this study was to empirically test a small component of these dynamic frameworks. We accomplished this through measuring intolerance of uncertainty—a predisposition towards fearing an uncertain future—as a predictor of retirement-related outcomes, via future time perspective and occupational future time perspective. In Study 1, based on a heterogenous two-wave sample of working adults, (T1 N = 975, T2 N = 875), we tested intolerance of uncertainty as a predictor of financial risk tolerance towards retirement, retirement saving behaviors, and motivation to continue working, via future time perspective. Study 1 revealed that intolerance of uncertainty had a significant indirect effect on motivation to continue working and financial risk tolerance towards retirement, via future time perspective—suggesting that tolerating uncertainty is beneficial for aging workers through shaping an open-ended future time perspective. In Study 2, we used a heterogenous three-wave sample of working adults (T1 N = 587, T2 N = 454, T3 N = 406) and evaluated intolerance of uncertainty as a predictor of perceived work ability, via occupational future time perspective. Consistent with expectations, Study 2 reinforced the conclusions of Study 1. Overall, we provide empirical support for aspects of these uncertainty regulation frameworks. We discuss our findings in the context of uncertainty regulation, (occupational) future time perspective, and successful workplace aging
Bringing Self-Determination Theory to the Forefront: Examining How Human Resource Practices Motivate Employees of All Ages to Succeed
No full textSelf-determination theory (SDT) is widely used in human resource (HR) practice studies to explain how HR practices impact work outcomes. However, there is little empirical evidence establishing the complete SDT mediational process in the HR domain, which entails basic psychological needs and motivation acting as mediators of relations between HR practices and work outcomes. The present study addresses this issue with a mixed methods approach. Using an item classification task with subject matter experts (N = 48), HR practices were classified as autonomy-, competence-, and relatedness-supportive. Based on this scheme, we tested an SDT-based conceptual model in a three-wave sample of working adults (N = 818). Results from Multilevel Structural Equation Modeling (MSEM) support the hypothesized model: basic psychological need satisfaction and autonomous motivation mediate the relationship between HR practice perceptions and work outcomes (performance, thriving, affective organizational commitment, and turnover intentions). Autonomy-supportive practices had a positive effect on autonomy need satisfaction, while competence-supportive practices had positive associations with all three basic psychological needs. Counterintuitively, relatedness-supportive practices had negative effects on autonomy and competence need satisfaction, and the relationship between relatedness-supportive practices and autonomy need satisfaction was moderated by chronological age. We discuss our findings in the context of prominent HR studies that utilize SDT and offer a supplemental age-inclusive HR practice scheme for HR managers interested in understanding the benefits of supporting basic psychological needs from both a motivation and workforce retention standpoint
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
