Studies investigating individual performance in knowledge-intensive work are finding that individual performance is a result, to some degree, of obtaining the right information to solve novel, challenging problems. Yet we know little about the role that the individual plays in the knowledge processes in multinationals and the relationship between individual knowledge sourcing activities and performance. Our expectation is that successful knowledge transfer will be based on an individual's intrinsic motivation, access to knowledge from explicit or tacit knowledge sources within and across firm boundaries, and position in the overall advice network of the multinational corporation. Using survey and social network data collected in one multinational consulting firm, we investigated the knowledge sourcing activities and informal advice networks for 1439 of the entire 1698 individuals in one multinational spread across 28 offices (84.7% response rate). Through hierarchical regression analysis we find that 1) intrinsic motivations are strongly related to creativity and efficiency and 2) MNCs should support individual level activities that include not only the use of internal knowledge sources but also the use of external knowledge sources. Research results also suggest that 3) there are different patterns of knowledge sourcing activities based on whether efficient or creative performance is the goal and 4) these differ significantly depending upon the functional group to which the individual belongs. Implications for theories of the knowledge-based view of the multinational corporation and practical implications for managers are discussed.  相似文献

We develop local influence diagnostics for a general binary regression model,and apply these methods to case-weight perturbations in four examples. In addition, we illustrate the correspondence between case-deletion diagnostics and local case-weight perturbation slopes and curvatures. We demonstrate that local influence diagnostics can provide a more computationally efficient means for obtaining analogous information to that yielded by case-deletion diagnostics, which can be thought of as global influence perturbations. We also assess the global consistency of patterns of local influence using these data examples.  相似文献

Climate change and degradation of ecosystem services functioning may threaten the ability of current agricultural systems to keep up with demand for adequate and inexpensive food and for clean water, waste disposal and other broader ecosystem services. Human health is likely to be affected by changes occurring across multiple geographic and time scales. Impacts range from increasing transmissibility and the range of vectorborne diseases, such as malaria and yellow fever, to undermining nutrition through deleterious impacts on food production and concomitant increases in food prices. This paper uses case studies to describe methods that make use of satellite remote sensing and Demographic and Health Survey data to better understand individual-level human health and nutrition outcomes. By bringing these diverse datasets together, the connection between environmental change and human health outcomes can be described through new research and analysis.  相似文献

This paper examines the relationship between gambling behavior and subjective wellbeing. It is often asserted that populations consist of different types of gamblers: those for whom gambling is a harmless leisure activity and those (pathological/problem gamblers) for whom the activity has harmful effects. One might, therefore, assume that subjective wellbeing will be negativity associated with an individual’s level of gambling addiction. Alternatively, gamblers may choose to gamble because they derive utility from participating in this activity and so the relationship between happiness and gambling might be positively correlated. In this paper we test this association, empirically, using data from the 2010 British Gambling Prevalence Survey. The statistically significant findings from this analysis support the hypothesis that individual wellbeing falls as gambling disorder increases.  相似文献

Essential elements such as copper and manganese may demonstrate U‐shaped exposure‐response relationships due to toxic responses occurring as a result of both excess and deficiency. Previous work on a copper toxicity database employed CatReg, a software program for categorical regression developed by the U.S. Environmental Protection Agency, to model copper excess and deficiency exposure‐response relationships separately. This analysis involved the use of a severity scoring system to place diverse toxic responses on a common severity scale, thereby allowing their inclusion in the same CatReg model. In this article, we present methods for simultaneously fitting excess and deficiency data in the form of a single U‐shaped exposure‐response curve, the minimum of which occurs at the exposure level that minimizes the probability of an adverse outcome due to either excess or deficiency (or both). We also present a closed‐form expression for the point at which the exposure‐response curves for excess and deficiency cross, corresponding to the exposure level at which the risk of an adverse outcome due to excess is equal to that for deficiency. The application of these methods is illustrated using the same copper toxicity database noted above. The use of these methods permits the analysis of all available exposure‐response data from multiple studies expressing multiple endpoints due to both excess and deficiency. The exposure level corresponding to the minimum of this U‐shaped curve, and the confidence limits around this exposure level, may be useful in establishing an acceptable range of exposures that minimize the overall risk associated with the agent of interest.  相似文献

ABSTRACT

Living examples of peoples’ sovereignty can illustrate the path toward positive people-centred alternatives to control by the capitalist State, wealthy private land-owners and corporations. Efforts to undermine Indigenous and other peoples’ sovereignty have been deliberate and continue to take place in industrialized and ‘developing’ countries. Yet peoples’ sovereignty has the capacity to unite and educate people in important ways. Many examples of education to promote peoples’ sovereignty are emerging, building on the knowledge that communities have generated over time. This is a very different educational model than the one most commonly recognized and implemented in industrialized societies. People working in higher education everywhere have the responsibility to educate our students about the history of colonization and destruction of peoples’ sovereignty, so that they understand the real history of their countries, to build alliances with other educators globally, and to form bonds of solidarity with peoples’ movements.  相似文献

In the United States the number of births to unmarried mothers is at a record high. Although being unmarried is a significant risk factor for low birth weight and preterm births, paternal presence may have a protective effect. In addition to marital status, paternity may be a proxy measure for paternal support. Virginia birth registry data were analyzed to investigate the effect of marital and paternity status on low birth weight and preterm births. Findings from this study show that women who reported being unmarried and with no paternity status were 1.6 (odds ratio = 1.57, 95% confidence interval = 1.41–1.75) and 1.4 (odds ratio = 1.39, 95% confidence interval = 1.21–1.61) times more likely to have preterm low birth weight and term low birth weight babies, respectively. Being unmarried and lack of established paternity appear to be significantly correlated with and may be important risk factors for preterm and low birth weight deliveries. Health care professionals should be aware of the potential role of paternal presence and marital status may play with respect to preterm births and low birth weight.  相似文献

Social information processing has emerged as an important construct in understanding children's interpersonal functioning. This article reviews (1) the theoretical models guiding research, (2) the development of normative and atypical social problem solving, and (3) the connection between social information processing and individual differences in functioning. Finally, this review ends with a summary of efficacy of programs aimed at preventing social information processing biases or intervening with youth who display dysfunctional social information processing skills.  相似文献

Social relationships can have considerable influence on physical and mental well-being in later life, particularly for those in long-term care settings such as assisted living (AL). Research set in AL suggests that other residents are among the most available social contacts and that co-resident relationships can affect life satisfaction, quality of life, and well-being. Functional status is a major factor influencing relationships, yet AL research has not studied in-depth or systematically considered the role it plays in residents' relationships. This study examines the influences of physical and mental function on co-resident relationships in AL and identifies the factors shaping the influence of functional status. We present an analysis of qualitative data collected over a one-year period in two distinct AL settings. Data collection included: participant observation, informal interviews, and formal in-depth interviews with staff, residents, administrators and visitors, as well as surveys with residents. Grounded theory methods guided our data collection and analysis. Our analysis identified the core category, “coming together and pulling apart”, which signifies that functional status is multi-directional, fluid, and operates in different ways in various situations and across time. Key facility- (e.g., admission and retention practices, staff intervention) and resident-level (e.g., personal and situational characteristics) factors shape the influence of functional status on co-resident relationships. Based on our findings, we suggest strategies for promoting positive relationships among residents in AL, including the need to educate staff, families, and residents.  相似文献
