The article closely examines the role of mechanistic effect models (e.g., population models) in the European environmental risk assessment (ERA) of pesticides. We studied perspectives of three stakeholder groups on population modeling in ERA of pesticides. Forty‐three in‐depth, semi‐structured interviews were conducted with stakeholders from regulatory authorities, industry, and academia all over Europe. The key informant approach was employed in recruiting our participants. They were first identified as key stakeholders in the field and then sampled by means of a purposive sampling, where each stakeholder identified as important by others was interviewed and asked to suggest another potential participant for our study. Our results show that participants, although having different institutional backgrounds often presented similar perspectives and concerns about modeling. Analysis of repeating ideas and keywords revealed that all stakeholders had very high and often contradicting expectations from models. Still, all three groups expected effect models to become integrated in future ERA of pesticides. Main hopes associated with effect models were to reduce the amount of expensive and complex testing and field monitoring, both at the product development stage, and as an aid to develop mitigation measures. Our analysis suggests that, although the needs of stakeholders often overlapped, subtle differences and lack of trust hinder the process of introducing mechanistic effect models into ERA.  相似文献

Much research has studied off-shore outsourcing from a Western client perspective. This article tries to shed light on what an Indian vendor perceives as important to manage large and complex strategic partnerships in IT outsourcing, and in particular how mutually profitable, long-term relationships with European clients are created and maintained, both at company and project levels. We investigate this issue through qualitative interviews with various vendor representatives in offshore and on-site teams in a top tier multinational company of Indian origin.In the analysis of interview accounts of close collaboration processes in two large and complex projects, where off-shoring of software development is moved to a strategic level, we found that the vendor was able to establish a strategic partnership through long-term engagement with the field of banking and insurance as well as through conscious relationship management with the clients. Three major themes describe important aspects of the strategic partnerships: 1) senior management commitment and employee identification with the projects, 2) mutual trust and transparency, and 3) cross-cultural understanding and sensitivity. The article draws attention to the important collaborative work done by people who are able to span boundaries in the complex organizational set-up of global IT development projects.  相似文献

Culturally sensitive juvenile delinquency and substance abuse interventions are relatively limited and unavailable to many first-time Hispanic juvenile offenders. The purpose of this study was to test the effectiveness of a culturally focused juvenile and substance abuse intervention program for first time Hispanic youth offenders. The intent of the program was to decrease juvenile recidivism and increase substance abuse resistance. Programa Shortstop is a family based intervention designed for Hispanic youth ages 9-17. The intervention was delivered to 352 youth and at least one parent/caregiver over the 5-year study period. For intervention youth, the results of the recidivism study (n = 321) indicated that 89% of youth participating in Programa Shortstop between 1995 to 1997 were not rearrested within one year of completing Programa Shortstop. Additionally, statistical paired t-test analysis found that the intervention model had a positive effect on legal knowledge and school related factors associated with substance abuse and delinquency. Parent participants demonstrated significant increases in knowledge related to substance abuse and the legal system.  相似文献

Adolescence is a critical period where many patterns of health and health behaviour are formed. The objective of this study was to investigate cross-national variation in the relationship between family affluence and adolescent life satisfaction, and the impact of national income and income inequality on this relationship. Data from the 2006 Health Behaviour in School-aged Children: WHO collaborative Study (N = 58,352 across 35 countries) were analysed using multilevel linear and logistic regression analyses for outcome measures life satisfaction score and binary high/low life satisfaction. National income and income inequality were associated with aggregated life satisfaction score and prevalence of high life satisfaction. Within-country socioeconomic inequalities in life satisfaction existed even after adjustment for family structure. This relationship was curvilinear and varied cross-nationally. Socioeconomic inequalities were greatest in poor countries and in countries with unequal income distribution. GDP (PPP US$) and Gini did not explain between country variance in socioeconomic inequalities in life satisfaction. The existence of, and variation in, within-country socioeconomic inequalities in adolescent life satisfaction highlights the importance of identifying and addressing mediating factors during this life stage.  相似文献

This paper seeks to develop management theory that can be used to increase the likelihood of ERP implementation success. The paper argues and demonstrates that an ERP implementation can be understood as an intended radical change that can be managed to some extent. But during the use of the system, incremental changes are bound to take place, which are unintended and difficult to manage. Using, therefore, and combining positivist and constructivist viewpoints, six different propositions on ERP implementation are developed. The paper reasons that organizations that understand these propositions are more likely to implement and use ERP successfully. The findings of a longitudinal case study of the implementation and use of BaaN in a Danish company support the propositions put forward in the paper.  相似文献

Recovery of interdependent infrastructure networks in the presence of catastrophic failure is crucial to the economy and welfare of society. Recently, centralized methods have been developed to address optimal resource allocation in postdisaster recovery scenarios of interdependent infrastructure systems that minimize total cost. In real-world systems, however, multiple independent, possibly noncooperative, utility network controllers are responsible for making recovery decisions, resulting in suboptimal decentralized processes. With the goal of minimizing recovery cost, a best-case decentralized model allows controllers to develop a full recovery plan and negotiate until all parties are satisfied (an equilibrium is reached). Such a model is computationally intensive for planning and negotiating, and time is a crucial resource in postdisaster recovery scenarios. Furthermore, in this work, we prove this best-case decentralized negotiation process could continue indefinitely under certain conditions. Accounting for network controllers' urgency in repairing their system, we propose an ad hoc sequential game-theoretic model of interdependent infrastructure network recovery represented as a discrete time noncooperative game between network controllers that is guaranteed to converge to an equilibrium. We further reduce the computation time needed to find a solution by applying a best-response heuristic and prove bounds on ε-Nash equilibrium, where ε depends on problem inputs. We compare best-case and ad hoc models on an empirical interdependent infrastructure network in the presence of simulated earthquakes to demonstrate the extent of the tradeoff between optimality and computational efficiency. Our method provides a foundation for modeling sociotechnical systems in a way that mirrors restoration processes in practice.  相似文献

This article explores the causes and timing of the abolition of the Danish slave trade in 1792. While the existing historiography highlights economic and humanitarian considerations behind the decision to decree abolition of the slave trade and situates such concerns within a Danish context, this article looks at ways in which trans-imperial influences on the Danish government and commercial ties between the Danish colonial empire and other slave trading polities were equally important factors in the move towards abolition.  相似文献

Perception is not just a cognitive, private experience, but achieved in and through interactive and practical actions in co‐operation with other semiotic agents. This article contributes to work on multisensory perception that is distributed as an interactional phenomenon between agents. Based on video‐ethnographic research conducted among visually impaired people, and an ethnomethodological, conversation‐analytical framework, the article contributes findings about the most basic sensory characteristics of distributed perception: co‐operation between sense‐able, action‐able, accountable semiotic agents that can communicate multisensorial information in order to solve situated and emerging problems together.  相似文献
