The general proposition that stress-related variables will be associated with discrepancies between chronological age and perceived personal age of working adults was examined. Responses from a field survey of day, afternoon, and night fixed-shift workers in a large manufacturing organization (n = 1674) were used to explore the relationships between a variety of reported stress-related variables and personal age constructs. Discrepancies between perceived personal age and chronological age were reported by a large proportion of the workers surveyed. Three categories of stress-related variables each accounted for a significant proportion of the variance in discrepancies. As hypothesized, the reported presence of stressors and the frequency/extent of strains (stress-related outcomes) were positively correlated with feeling older than one's chronological age. In addition, the reported presence of support mechanisms for coping with stressors was negatively correlated with feeling older than one's chronological age. The manner in which work and non-work stress may impinge upon personal age perceptions is discussed, and appropriate avenues for future research in this domain are considered.  相似文献

Research suggests that hurricane‐related risk perception is a critical predictor of behavioral response, such as evacuation. Less is known, however, about the precursors of these subjective risk judgments, especially when time has elapsed from a focal event. Drawing broadly from the risk communication, social psychology, and natural hazards literature, and specifically from concepts adapted from the risk information seeking and processing model and the protective action decision model, we examine how individuals’ distant recollections, including attribution of responsibility for the effects of a storm, attitude toward relevant information, and past hurricane experience, relate to risk judgment for a future, similar event. The present study reports on a survey involving U.S. residents in Connecticut, New Jersey, and New York (n = 619) impacted by Hurricane Sandy. While some results confirm past findings, such as that hurricane experience increases risk judgment, others suggest additional complexity, such as how various types of experience (e.g., having evacuated vs. having experienced losses) may heighten or attenuate individual‐level judgments of responsibility. We suggest avenues for future research, as well as implications for federal agencies involved in severe weather/natural hazard forecasting and communication with public audiences.  相似文献

Six‐, 12‐, and 18‐month‐old English‐hearing infants were tested on their ability to discriminate nonword forms ending in the final stop consonants /k/ and /t/ from their counterparts with final /s/ added, resulting in final clusters /ks/ and /ts/, in a habituation–dishabituation, looking time paradigm. Infants at all 3 ages demonstrated an ability to discriminate this type of contrast, a contrast that constitutes one phonetic cue for the English morphological concepts of plural, possession, and person. These results suggest that across a significant portion of the development of infants' speech perception, this type of final contrast is discriminable.  相似文献

This article summarizes 8 presentations from Group 8 on the theme “Training of Researchers and Practitioners,” which were part of the 2007 joint symposium of the International Association for Educational and Vocational Guidance, Society for Vocational Psychology, and National Career Development Association held in Padua, Italy. Three themes representing challenges for the profession emerged from the presentations: (a) the need for public policies addressing career development, (b) the need for greater competency standardization, and (c) the need to create innovative training programs. Discussion group participants presented creative strategies for addressing these challenges.  相似文献

There is a large literature suggesting that “WIC works” to improve birth outcomes. However, methodological limitations related to selection into the Women, Infants, and Children (WIC) program have left room for doubt about this conclusion. This article uses birth records from New York City to address some limitations of the previous literature. We estimate models with mother fixed effects to control for fixed characteristics of mothers and we directly investigate the way that time‐varying characteristics of mothers affect selection into the WIC program. We find that WIC is associated with reductions in low birth weight, even among full‐term infants, and with reductions in the probability that a child is “small for dates.” These improvements are associated with a reduction in the probability that the mother gained too little weight during pregnancy. Improvements tend to be largest for first born children. We also find that women on WIC are more likely to be diagnosed with chronic conditions, and receive more intensive medical services, a finding that may reflect improved access to medical care.

Since the early 1950s, the National Heart, Lung, and Blood Institute (NHBLI) has conducted a long series of influential randomized clinical trials in heart, lung, and blood diseases. The biostatisticians at the Institute have been central to the design, conduct, monitoring, and final analyses of these trials. The uniquely favorable deck of cards the group of biostatisticians at the Institute has been dealt over the six and half decades of the group's life has led to contributions that have had a major impact on the fields of biostatistics and clinical trials. The leaders of the NHLBI and its several Divisions have valued the independence, creativity, and collaborative interactions of statisticians within the Institute. The medical problems the Institute faced impelled the statisticians to develop methodology that would address questions of great public importance. Perhaps most importantly, the individual members of the group had a collective vision passed from member to member over time that new methodology must fit the questions being asked. The group has always had the technical ability to develop new methods and the conviction that they were responsible for ensuring that they could explain their methods to the clinicians with whom they worked.  相似文献

Over the last 20+ years, globalization has made international trade and investment more efficient and productive. In the absence of coordinated global regulatory regimes, it has also made multinational corporations (MNCs) impervious to social concerns in the countries where they operate. There is considerable debate in the academic, political, and business arena as to the causes of the apparently inequitable distribution of benefits between labor and capital. Notwithstanding, the relative merits of this debate, and facing tremendous societal pressure, companies have adopted voluntary codes of conduct to ensure that workers making products for them in poor and developing countries are protected from hazardous working conditions and receive wages that meet local laws and market conditions. These codes, however, suffer from a lack of credibility and proof of substantive compliance. A new type of nongovernmental organization (NGO) has emerged that monitors a company's compliance with prespecified standards and provides assurance to the external stakeholders that the company has fulfilled its voluntary obligations. From an historical perspective, this has been an innovative phenomenon where the monitoring organization purports to act as an honest broker to ensure all concerned that the company/industry has fulfilled its obligations. In this article, we undertake a thorough examination of two such organizations, that is, Fair Labor Association, and Social Accountability International, that have played a pioneering role in bridging the gap between societal expectations and corporate performance. We examine their governance structures, operating procedures, monitoring standards, and public disclosure of findings, and above all, their success in improving the level of corporate compliance with their self‐created codes or standards. Unfortunately, our findings and conclusions are disappointing. In our view, the two groups have mostly failed to meet their avowed goals. Rather than using their NGO status to help companies improve their code compliance, they have suffered from managerial capture and have been reduced to corporate apologists.  相似文献

In 3 experiments, the temporal processing sequence of local and global visual properties was investigated with 3‐month‐old infants. Across the experiments, a global pattern was discriminated under conditions of less familiarization than was necessary for local elements to be discriminated, thus indicating a global precedence in the sequence of visual processing at 3 months of age. Patterns of discrimination were also observed to vary as a function of individual differences in infants' look duration. Furthermore, the pattern of novelty and familiarity preferences for short‐looking infants varied in complex ways as a function of familiarization time: Preferences for novel global properties were supplanted by familiarity preferences at the point in familiarization at which infants first became sensitive to local properties.  相似文献

Infant phonetic perception reorganizes in accordance with the native language by 10 months of age. One mechanism that may underlie this perceptual change is distributional learning, a statistical analysis of the distributional frequency of speech sounds. Previous distributional learning studies have tested infants of 6–8 months, an age at which native phonetic categories have not yet developed. Here, three experiments test infants of 10 months to help illuminate perceptual ability following perceptual reorganization. English‐learning infants did not change discrimination in response to nonnative speech sound distributions from either a voicing distinction (Experiment 1) or a place‐of‐articulation distinction (Experiment 2). In Experiment 3, familiarization to the place‐of‐articulation distinction was doubled to increase the amount of exposure, and in this case infants began discriminating the sounds. These results extend the processes of distributional learning to a new phonetic contrast, and reveal that at 10 months of age, distributional phonetic learning remains effective, but is more difficult than before perceptual reorganization.  相似文献
