A critical step for geostatistical prediction is estimation of variogram from the data. One of the popular methods estimating variogram is a smoothed version of classical nonparametric variogram estimator. In this paper we investigate its theoretical and empirical properties to provide useful information for using it. The main results are based on asymptotic theories (i.e., risk and central limit theorem) under nearly infill domain sampling. Simulation is also employed to make our points. 相似文献

This study aimed to address the social contexts of Korean society in which diverse social interactions of foreign wives take place and to identify coping strategies to construct positive social identities. Social identities are often reconstructed as a result of dynamic interactions with various situations. Using the conceptual framework of social identity theory, this study attempted to uncover the social contexts that shape foreign wives' social identities. This study, using the qualitative approach, selected nine Filipino and Vietnamese participants who were married to Korean men. The data were collected by in‐depth interviews, a focus group with three Vietnamese participants, field notes, participant observation, and photo documents. In the section on study findings, this study addressed Korean social contexts, in which Korean government has been providing a variety of multicultural policies and services for helping foreign wives successfully adapt to Korea. This study also found various forms of stereotypes and discrimination against foreign wives and presented their discrimination experiences. Diverse ways to cope with such negative experiences are presented in the last section. Given the findings, the researcher suggests that policies and programs should promote foreign wives' integration in Korean society. 相似文献

Personal ties are generally regarded as important to big business growth in Malaysia, particularly after the New Economic Policy (NEP) in the 1990s. Common types are informal ones established between multi-ethnic big business people and Malay key state and political leaders. Other types of ties, company directorship links and informal ties, are seldom studied especially those between the business people and former state bureaucrats and corporate professionals. Thus, by conceptualising the directorship links and informal personal ties as social networks, the author conducted a sociological analysis of some intra- and inter-ethnic directorship links and ties established by four prominent big businessmen after the NEP in the 1990s. This article reports the main finding on the links and ties becoming a common organisational mechanism of business groups owned and controlled by the businessmen, besides providing access to the state. Therefore, another understanding of inter- and intra-ethnic personal ties in big business growth, especially after the NEP is achieved. 相似文献

Grounded in first- and second-level agenda building, this study explored the role of the U.S. Senate Majority Leader in shaping the salience of issues and issue attributes in news media coverage and policymaking in 2011. A total of 358 public relations messages, 164 newspaper articles, and 83 policymaking documents were analyzed. Significant correlations were found supporting agenda-building linkages at both levels. Different types of information subsidies were explored, including press releases, blog posts, Facebook posts, and Twitter messages. 相似文献

Polyamory is characterized by simultaneous consensual romantic relationships with multiple partners. Polyamory allows individuals to fulfill their relationship needs with multiple romantic partners, yet researchers have not identified how having needs met in one romantic relationship may be related to relationship outcomes in a concurrent relationship. Polyamorous individuals (N=1,093) completed online measures of need fulfillment, relationship satisfaction, and commitment for two concurrent romantic relationships. Participants reported high levels of need fulfillment and satisfaction in both relationships. Need fulfillment with one partner negatively predicted approximately 1% of the variance in relationship satisfaction with the other partner; however, there was no association between need fulfillment with one partner and commitment to the other. Generally, the findings suggest that polyamorous relationships are relatively independent of one another. This study provides initial evidence that polyamory may be a viable and fulfilling alternative way of conducting intimate relationships. 相似文献

This article examined the theoretical meanings of pension rights and analyzed their effects on women's economic risks in developed countries. First, based on the status of a citizen, worker, parent, and spouse, this study investigated how pension benefits are guaranteed as a citizen regardless of work history, the degree to which women's disadvantageous situations in the labor market and unpaid work are compensated by public pension as workers and parents, and how marital status is treated in the different pension systems. Second, analysis of the effect of pension rights showed that individual rights is a significant factor to prevent economic risks of elderly women. Derived rights did not seem to secure the economic welfare of elderly women, at least in a comparative context. This finding suggested that developing individual rights, rather than derived rights, is the way to guarantee long‐term elderly women's economic welfare. 相似文献

The Value of Information in Decision‐Analytic Modeling for Malaria Vector Control in East Africa 下载免费PDF全文

Decision analysis tools and mathematical modeling are increasingly emphasized in malaria control programs worldwide to improve resource allocation and address ongoing challenges with sustainability. However, such tools require substantial scientific evidence, which is costly to acquire. The value of information (VOI) has been proposed as a metric for gauging the value of reduced model uncertainty. We apply this concept to an evidenced‐based Malaria Decision Analysis Support Tool (MDAST) designed for application in East Africa. In developing MDAST, substantial gaps in the scientific evidence base were identified regarding insecticide resistance in malaria vector control and the effectiveness of alternative mosquito control approaches, including larviciding. We identify four entomological parameters in the model (two for insecticide resistance and two for larviciding) that involve high levels of uncertainty and to which outputs in MDAST are sensitive. We estimate and compare a VOI for combinations of these parameters in evaluating three policy alternatives relative to a status quo policy. We find having perfect information on the uncertain parameters could improve program net benefits by up to 5–21%, with the highest VOI associated with jointly eliminating uncertainty about reproductive speed of malaria‐transmitting mosquitoes and initial efficacy of larviciding at reducing the emergence of new adult mosquitoes. Future research on parameter uncertainty in decision analysis of malaria control policy should investigate the VOI with respect to other aspects of malaria transmission (such as antimalarial resistance), the costs of reducing uncertainty in these parameters, and the extent to which imperfect information about these parameters can improve payoffs. 相似文献
