This paper discusses the relationship between corporate volunteering and civic engagement outside the workplace in Russia, proceeding from a mixed-method approach. The quantitative findings are based on a comparison between employees in 37 Russian companies who participated in corporate volunteering (N = 399) and those who did not (N = 402). Using binary logistic regression analysis, we demonstrate that employee participation in corporate volunteering is positively related to four forms of civic engagement outside the workplace: informal volunteering, formal volunteering, formal monetary donation, and informal monetary donation. In addition, we draw on information obtained from interviews with 10 corporate volunteers, as well as with all 37 company corporate volunteering managers, to develop a general explanation for why corporate volunteering might lead to civic engagement. We identify three primary explanations. First, trust in companies can be converted into increased trust in social institutions. Second, corporate volunteering can expose employees to other realities, thereby leading them to rethink their priorities. Third, corporate volunteering socializes employees to volunteering, thus making them more likely to incorporate volunteering into their personal repertoires of activities. Corporate volunteering appears to be an effective mechanism for stimulating civic engagement and volunteering infrastructure in post-communist countries. 相似文献

Urban and agricultural soils: conflicts and trade-offs in the optimization of ecosystem services 总被引:2,自引:0,他引:2
H. Setälä R. D. Bardgett K. Birkhofer M. Brady L. Byrne P. C. de Ruiter F. T. de Vries C. Gardi K. Hedlund L. Hemerik S. Hotes M. Liiri S. R. Mortimer M. Pavao-Zuckerman R. Pouyat M. Tsiafouli W. H. van der Putten 《Urban Ecosystems》2014,17(1):239-253
On-going human population growth and changing patterns of resource consumption are increasing global demand for ecosystem services, many of which are provided by soils. Some of these ecosystem services are linearly related to the surface area of pervious soil, whereas others show non-linear relationships, making ecosystem service optimization a complex task. As limited land availability creates conflicting demands among various types of land use, a central challenge is how to weigh these conflicting interests and how to achieve the best solutions possible from a perspective of sustainable societal development. These conflicting interests become most apparent in soils that are the most heavily used by humans for specific purposes: urban soils used for green spaces, housing, and other infrastructure and agricultural soils for producing food, fibres and biofuels. We argue that, despite their seemingly divergent uses of land, agricultural and urban soils share common features with regards to interactions between ecosystem services, and that the trade-offs associated with decision-making, while scale- and context-dependent, can be surprisingly similar between the two systems. We propose that the trade-offs within land use types and their soil-related ecosystems services are often disproportional, and quantifying these will enable ecologists and soil scientists to help policy makers optimizing management decisions when confronted with demands for multiple services under limited land availability. 相似文献

In this article the characteristics and determinants of the information content of management earnings forecasts of the German DAX and MDAX companies between 2002 and 2005 are analyzed. As proxy for the information content I use the precision of the wording of a forecast. I can show that the forecasts of MDAX companies are more precisely formulated than those of DAX companies. Furthermore forecasts are formulated more precisely, when companies have, (1) a lower percentage of intangible assets, (2) lower market capitalization, (3) lower volatility of earnings and (4) a higher need for external financing. 相似文献

Aesthetic approaches seek to enrich knowledge about the ‘sensible’ aspects of experience. The ‘aesthetic dimension’ of shipboard organizational life is evoked and co‐created through multiple aesthetic categories such as the agogic, the sacred, and the sublime rendered through multiple sensory experiences of life aboard. A researcher and sailor‐informant co‐authored aesthetic reading contributes to a growing niche of aesthetic‐based research within organization studies. Our article explores collaboration as an important element of the aesthetic project. Possibilities for future aesthetic inquiries are also considered. 相似文献

Exploiting the exogenous variation in user fees caused by a Swedish childcare reform, we are able to identify the causal effect of childcare costs on fertility in a context in which childcare enrollment is almost universal, user fees are low, and labor force participation of mothers is very high. Anticipation of a reduction in childcare costs increased the number of first and higher-order births, but only seemed to affect the timing of second births. For families with many children we also find a marginally significant negative income effect on fertility. 相似文献

Political-economic classics of different schools agreed that capitalism inherently and inevitably leads to a decline of market principles. We analyze indicators of liberalization policies for 21 OECD-countries in five economic and social policy fields and demonstrate that western industrialized countries are subject of a convergent trend towards market-creating policies??in stark contrast to the theoretical expectations of several political economy authors. At the latest during the first half of the eighties, the western democracies entered a new phase of economic liberalization, which continues up to the present. A methodological implication of our findings suggests that the methods of causal analysis of convergent liberalization policies may not be the same as those who have been applied for the analysis of development and consolidation of the varieties of capitalism in the postwar era. 相似文献

A quantitative microbial risk assessment (QMRA) according to the Codex Alimentarius Principles is conducted to evaluate the risk of human salmonellosis through household consumption of fresh minced pork meat in Belgium. The quantitative exposure assessment is carried out by building a modular risk model, called the METZOON-model, which covers the pork production from farm to fork. In the METZOON-model, the food production pathway is split up in six consecutive modules: (1) primary production, (2) transport and lairage, (3) slaughterhouse, (4) postprocessing, (5) distribution and storage, and (6) preparation and consumption. All the modules are developed to resemble as closely as possible the Belgian situation, making use of the available national data. Several statistical refinements and improved modeling techniques are proposed. The model produces highly realistic results. The baseline predicted number of annual salmonellosis cases is 20,513 ( SD 9061.45). The risk is estimated higher for the susceptible population (estimate 4.713 × 10−5 ; SD 1.466 × 10−5 ) compared to the normal population (estimate 7.704 × 10−6 ; SD 5.414 × 10−6 ) and is mainly due to undercooking and to a smaller extent to cross-contamination in the kitchen via cook's hands. 相似文献

In this paper we investigate differences between the organizational values of ministries and semi-autonomous executive agencies
(quangos) that operate at arms’ length. Quangos are expected to operate more business-like, hence they can be expected to
value profitability and other NPM-related values higher than ministries. Value incongruence between quangos and ministries
is hypothesized to decrease their level of trust. These hypotheses are tested, using combined data from two Dutch surveys
(n = 324). The results confirm the expectations, although different types of quangos have different degrees of value (in)congruence,
which may lead to variations in the quality of the relationship with their parent ministry. 相似文献

In these times, when fame is available to almost anyone, it is worth being able to measure the extent and dimensions of a person's charisma. Most of the research on charisma to date is restricted to the area of leadership. In this article, however, charisma is generalized to take in all human beings and is conceptualized as a multi-dimensional cognitive-affective phenomenon. The article presents a pilot study aimed at providing an adequate operational definition of the construct as well as an initial tool for its measurement. A following literature review shows how authors have developed the concept of charisma and its initial operational dimensions for empirical research. A questionnaire is developed in three stages. The factor analyses applied in stages two and three point towards a six-factor solution (i.e. six dimensions of charisma). Further analysis reveals that the developed instrument is reliable and viable as well as applicable for future theoretical and practical work. 相似文献
