The structure of work values: A cross cultural comparison

Several years ago a research project on work values was originated. The study strived to examine the relative importance of work value items and to analyze the structure of the domain for samples from various cultural environments. A facet definition of work values was suggested that provided guidelines for constructing the Work Values Questionnaire and the formulation of hypotheses regarding the structure of relationships among components of work values. Based on data collected from 2280 respondents in eight countries the hypotheses were tested by means of Guttman's Smallest Space Analysis. The results support the hypotheses. An empirical double-ordered conceptual system, a radex structure, was obtained in each of the samples reflecting the facets of the definition: modality of outcome — cognitive, affective and instrumental, and system - performance contingency — reward, resource. In terms of the issue of cultural differences the results indicate the presence of cultural differences in the rating of a limited number of specific values. These differences are only minor variations within a much broader pattern of structural similarity. The fact that essentially the same structure was obtained in eight independent samples lends substantial support to the definitional framework of work values suggested.     

Assessing the costs for adaptation of marine constructions to sea-level rise

Marine constructions are highly vulnerable to climate change and sea-level rise (SLR), leading to increased risk rates of destruction and the potential closure of ports, harbors, and marinas along the coast. We present a cost-adjustment analysis for such constructions along the south-eastern Mediterranean coast, which takes into account the physical characteristics of the constructions, and environmental uncertainty factors. At 0.5 m SLR, the estimated adjustment cost is USD 280 million, and at 1 m SLR, the estimated cost is USD 505 million. These costs are equivalent to 0.091% and 0.165% of the Israeli gross domestic production, respectively. Although high, these adjustment costs are lower than the costs of future damage that will accrue if we fail to act. This implies that the adaptation-policy approach to controlling for the risk of SLR will provide benefits to the economic marine sectors and the public at large.     

The effect of workers' visibility on effectiveness of intervention programs: supervisory-based safety interventions

INTRODUCTION: This paper discusses an organizational change intervention program targeting safety behaviors and addresses important considerations concerning the planning of organizational change. Using layout of the plant as a proxy for ease of daily leader-member interaction, the effect of workers' visibility on the effectiveness of supervisory-based safety (SBS) interventions is examined. Through a reinforcement-learning framework, it is suggested that visibility can affect supervisors' incentive to interact with subordinates regarding safety-related issues. METHOD: Data were collected during SBS intervention studies in five manufacturing companies. RESULTS: Results suggest a reinforcement cycle model whereby increased visibility generates more frequent exchanges between supervisors and employees, resulting in improved safety behavior among employees. In turn, employees' safer behavior reinforces continued supervisory safety-related interaction. CONCLUSION AND IMPACT ON INDUSTRY: Visibility is an important moderator in supervisory based safety interventions, and can serve to increase workplace safety. Implications of these findings for safety are discussed.     

The effects of leadership dimensions,safety climate,and assigned priorities on minor injuries in work groups

This study is based on three premises: (a) Leadership style affects the level of concern for subordinate safety; (b) Concern for safety, operationalized with supervisory practices, provides the source for safety climate perceptions; and (c) Safety priority as assigned by higher superiors influences supervisory safety practice independently of leadership style. Assigned safety priority was expected to moderate the relationship between leadership style and injury rate in organizational subunits, with safety climate mediating this leadership–injury relationship due to its demonstrable effect on safety behavior. A within‐group split‐sample analysis of 42 work groups, coupled with prospective design, indicated that transformational and constructive leadership predicted injury rate, while corrective leadership provided indirect, conditional prediction. Leadership effects were moderated by assigned safety priorities and mediated by commensurate safety‐climate variables. The results suggest that transformational and transactional leadership provide complementary modes of (mediated and moderated) influence on safety behavior of group members.

General self‐efficacy and self‐esteem: toward theoretical and empirical distinction between correlated self‐evaluations

To test whether general self‐efficacy and self‐esteem relate differently to motivational and affective constructs, we collected data from samples in academic and work settings. Results suggest that general self‐efficacy is more highly related to motivational variables than is self‐esteem, whereas self‐esteem is more highly related to affective variables than is general self‐efficacy, as hypothesized. Furthermore, results support the notion that motivational and affective states differentially mediate the relationships of general self‐efficacy and self‐esteem with task performance. These results confirm the theoretical distinction between general self‐efficacy and self‐esteem and suggest that failure to distinguish between them might exact a price in terms of precision, validity, and understanding of determinants of performance. Implications for research and practice in organizations are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

The justice perspective of job stress

The study presents a new variable, role justice, pertaining to the perceived fairness of role senders reaction when the focal individual is under conflict, ambiguity, overload, or restricted latitude. The effect of this variable on symptoms of strain was explored, with the expectation of finding either additive or interactive effects vis-à-vis the above four role stressors. Using hierarchical multiple regression, the data supported the additive model which suggested that role injustice constitutes an additional source of stress. The study was conducted with a sample of hospital nurses, known to have significant levels of job stress. The results suggest that the role stress model ought to be expanded to include social appraisal constructs because of the social origin of the stressor variables it deals with.     

X-ray diffraction and SEM study of kidney stones in Israel: quantitative analysis, crystallite size determination, and statistical characterization

Urinary calculi have been recognized as one of the most painful medical disorders. Tenable knowledge of the phase composition of the stones is very important to elucidate an underlying etiology of the stone disease. We report here the results of quantitative X-ray diffraction phase analysis performed on 278 kidney stones from the 275 patients treated at the Department of Urology of Hadassah Hebrew University Hospital (Jerusalem, Israel). Quantification of biominerals in multicomponent samples was performed using the normalized reference intensity ratio method. According to the observed phase compositions, all the tested stones were classified into five chemical groups: oxalates (43.2%), phosphates (7.7%), urates (10.3%), cystines (2.9%), and stones composed of a mixture of different minerals (35.9%). A detailed analysis of each allocated chemical group is presented along with the crystallite size calculations for all the observed crystalline phases. The obtained results have been compared with the published data originated from different geographical regions. Morphology and spatial distribution of the phases identified in the kidney stones were studied with scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). This type of detailed study of phase composition and structural characteristics of the kidney stones was performed in Israel for the first time.
