Family-businesses draw both their strengths and weaknesses from the combination of two systems with different rules. This fact is revealed drastically, when family-businesses are passed over to the next generation. This transition marks one of the biggest milestones in the life-cycle of a family-business and therefore often fails. What exactly is the task, the following generation is facing? The main idea of this text according to the ideas of constructivism is that the following generation has to discover its own and the construction of all participants of the transition regarding reality. This is necessary to enable the company to create a (new) stable construction of itself. 相似文献

Influence of vegetation composition on runoff in two simulated green roof experiments 总被引:2,自引:1,他引:1
Despite the fact that green roofs are based upon living systems, the majority of published research literature contains little
specific information on the contribution of plants to the various functions and properties of green roofs. Furthermore, there
has been little investigation of the influence of the composition of vegetation on the physical properties of a green roof
system. This paper reviews previously published material that throws light on the role of vegetation composition on green
roof function, with particular regard to rainwater runoff. Two experiments at the University of Sheffield, UK, are considered
in detail: (a) An outdoor lysimeter experiment that investigated the quantity of runoff from trays containing 100 mm of growing
medium and combinations of grasses and forbs, together with bare substrate, and (b) a greenhouse experiment using simulated
rainfall to estimate the amount of rainfall intercepted by different vegetation types. In both cases the vegetation ranged
from simple monocultures of forbs and grasses through to complex mixtures of both. In both cases, the composition of the vegetation
was found to significantly affect both the amount of water retained and released from the system. 相似文献

On the basis of a sample of 184 top executives, we investigated the roles of decision quality and perceived uncertainty in the relationship between decision comprehensiveness and performance. Our results show that decision quality mediates a large proportion of the comprehensiveness–performance relationship and may thus provide a more proximate outcome measure of the effect of comprehensiveness. In addition, we found that perceived uncertainty directly affects the level of comprehensiveness in organizations rather than moderating its effect on performance as conceptualized by previous research. Based on the integration of behavioral and information processing theories we suggest that more process-oriented measures such as decision quality and perceived uncertainty may overcome conflicting empirical results in the field. 相似文献

Compared with conventional products, sustainable products continue to attract relatively lower market shares. To increase customer acceptance, many sustainable products feature third-party certification labels (TPCL), yet it is unclear whether TPCL are effective and what processes and boundary conditions define their role in consumer decision making. Across three experimental studies, this research determines that sustainable products are characterized by credence qualities, associated with increased perceptions of risk, which negatively influence consumers' purchase intentions. Drawing on signaling theory, this study also shows that TPCL on sustainable products provide brand-like information cues that reduce the perceived risk of sustainable products. Finally, a third experimental study demonstrates that consumers must perceive TPCL as credible for them to reduce consumers’ risk perceptions. 相似文献

Occupational stress in universities: staff perceptions of the causes, consequences and moderators of stress 总被引:4,自引:0,他引:4
In recent years, the Australian university sector has undergone large-scale organizational change, including restructuring, downsizing and government funding cuts. At the same time, research from across the globe reports an alarming increase in the occupational stress experienced by university staff. We report on the first phase of a longitudinal investigation of occupational stress. A total of 22 focus groups were conducted with a representative sample of 178 academic and general staff from 15 Australian universities. The groups focused on understanding staff 's experience of occupational stress, and perceptions of the sources, consequences and moderators of stress. Both general and academic staff reported a dramatic increase in stress during the previous 5 years. As a group, academic staff reported higher levels of stress than general staff. Five major sources of stress were identified including: insufficient funding and resources; work overload; poor management practice; job insecurity; and insufficient recognition and reward. The majority of groups reported that job-related stress was having a deleterious impact on their professional work and personal welfare. Aspects of the work environment (support from co-workers and management, recognition and achievement, high morale, flexible working conditions), and personal coping strategies (stress management techniques, work/ non-work balance, tight role boundaries and lowering standards), were reported to help staff cope with stress. The findings provide a timely insight into the experience of stress within universities. 相似文献

On the Effect of Probability Distributions of Input Variables in Public Health Risk Assessment 总被引:1,自引:0,他引:1
A central part of probabilistic public health risk assessment is the selection of probability distributions for the uncertain input variables. In this paper, we apply the first-order reliability method (FORM)(1–3) as a probabilistic tool to assess the effect of probability distributions of the input random variables on the probability that risk exceeds a threshold level (termed the probability of failure) and on the relevant probabilistic sensitivities. The analysis was applied to a case study given by Thompson et al. (4) on cancer risk caused by the ingestion of benzene contaminated soil. Normal, lognormal, and uniform distributions were used in the analysis. The results show that the selection of a probability distribution function for the uncertain variables in this case study had a moderate impact on the probability that values would fall above a given threshold risk when the threshold risk is at the 50th percentile of the original distribution given by Thompson et al. (4) The impact was much greater when the threshold risk level was at the 95th percentile. The impact on uncertainty sensitivity, however, showed a reversed trend, where the impact was more appreciable for the 50th percentile of the original distribution of risk given by Thompson et al. 4 than for the 95th percentile. Nevertheless, the choice of distribution shape did not alter the order of probabilistic sensitivity of the basic uncertain variables. 相似文献

Philip S. Gorski 《Sociological methodology》2004,34(1):1-33
Despite the lip service which many sociologists pay to Popper's hypothetico‐deductive model (HDM) of theory testing, few if any major social theories have been definitively falsified. The reason is that sociological explanations do not fit the deductivist model of explanation: They do not contain universal or statistical "covering laws" from which falsifiable hypotheses could be deduced. Sociological explanations are better conceived in realist terms as causal models of the social processes that produce certain outcomes. While few models are completely false, some are nonetheless more empirically adequate than others. This essay argues that (1) the CLM is inadequate to sociology and that (2) attempts to reformulate the HDM are therefore destined to fail. It then outlines (3) a constructive realist model (CRM) of sociological explanation and uses it to develop (4) explanatory realist (ER) criteria for evaluating explanations. Deductivist and realist approaches to methodology are then compared through an examination of Skocpol's States and Social Revolutions . 相似文献
