The submitted paper proposes the possible use of integrated semi-quantitative risk assessment of groundwater resources. There are risks resulting from both natural and anthropogenic hazard sources. Activation of these types of hazard sources can cause damage to, or destruction of, particular hydrogeological structures and technological equipment of selected groundwater resources suitable for the emergency drinking water supply of the population. The process of risk assessment is based on the described register of hazards, including semi-quantitative assessment of the frequency with which the assessed sources of hazards are activated, the register of sensitivity together with the semi-quantitative sensitivity assessment of selected threatened elements of the assessed water resource and the determination of their criticality. The semi-quantitative risk assessment should become one of the important criteria for classifying groundwater resources which have been proposed for emergency water supply. The classification carried out on the basis of the above-mentioned principle can contribute to faster selection and effective use of groundwater resources, as well as to the enhancement of emergency and crisis planning systems when the public system is either damaged or destroyed. 相似文献

To develop further insight into antecedents of the CEO's psychological orientation toward the firm, we investigate what might lead CEOs to identify with their firms. Although research suggests that CEO organizational identification can be quite consequential for the firm, little research attention has been paid to its determinants. To predict how the special context of the CEO position might lead to identification, we consider a set of motives that members have for identifying with their organizations and consider how unique features of the CEO position might be relevant to those motives. Our theory and supportive findings help explain how the context of the CEO position, including variables often conceptualized as control mechanisms in agency theory research, can have important effects on subsequent CEO organizational identification.

Which factors facilitate the identification of business opportunities for sustainable development? To answer this question, we develop a process model of sustainable opportunity identification. We argue that sustainable opportunity identification is a process with transitions from problem to solution identification and from solution to sustainable opportunity identification. Moreover, the transitions are facilitated by two factors—awareness of adverse consequences and entrepreneurial attitude—providing motivation and direction in the process. We tested our model in a field study (N = 107) and two experiments (N = 53 and N = 69). Our findings show that awareness of adverse consequences and entrepreneurial attitude influence the process of sustainable opportunity identification, explaining under which conditions people are more likely to identify business opportunities for sustainable development. Our study thus contributes to the field of sustainable entrepreneurship. 相似文献
