Intimate partner violence (IPV) in late life takes various forms including physical harm, sexual assault, and murder. Using national newspaper reports of IPV among elders, we identified the types of violence reported most frequently in media and examined how the abuse was conceptualized by reporters. We found that most cases of IPV reported involved murder, with men as perpetrators and women as victims. Caregiving stress and health problems were frequently cited as contributing factors in the cases. Interpreting these findings from a feminist perspective, we suggest implications for practitioners working with older adults. 相似文献

This paper is aimed at comparing simulation against spreadsheets as decision support tools to properly manage project supply chain in the offshore oil and gas industry. The paper presents a case study related to the problem of sizing a chain for pipeline laying from an offshore field in the Barents sea to the Russian coast. Results obtained through a spreadsheet developed by an oil and gas company have been compared to the ones gathered from an ad hoc simulation model. A simulation model with no stochastic variable has been introduced: results are quite similar to the ones of the spreadsheet, which allowed to validate the simulation model. However, the spreadsheet cannot take into account the continuous move of the pipe-lay vessel while laying the pipes and it does not consider stochastic variables whose effect in real life is not negligible. Both weaknesses above are discussed. 相似文献

Measuring Citizen Satisfaction with Aspects of Public Services from a Local Authority and Determining Their Importance: A Case Study 总被引:1,自引:0,他引:1
Rosanna Giannoccaro Nicola Costantino A. Domenico Ludovico Roberto Pietroforte 《Public Organization Review》2008,8(1):1-15
The measurement of service quality is a theme of great importance to service providers, particularly public agencies. Over
the years their role has been changing by providing more and more high quality services, away from basic ones. In this paper
the service quality of a local government is analyzed through the measurement of customer satisfaction. The analysis, based
on a questionnaire survey, identified and classified the most essential factors that make up the customer satisfaction with
the services provided by the Demographic Department of Gioia del Colle, a town in southern Italy.

AbstractWhen the mixed chart proposed by Aslam et al. (2015) is in use, the sample items are classified as defective or not defective and, depending on the number of defectives, the quality characteristic X of the sample items are also measured. In this case, an Xbar chart decides the state of the process. The previous conforming/non-conforming classification truncates the X distribution and, because of that, the mathematical development to obtain the ARLs is complex. Aslam et al. (2015) didn’t pay attention to the fact that the X distribution is truncated and, due to that, they obtained incorrect ARLs. 相似文献

The International Council for Harmonization (ICH) E9(R1) addendum recommends choosing an appropriate estimand based on the study objectives in advance of trial design. One defining attribute of an estimand is the intercurrent event, specifically what is considered an intercurrent event and how it should be handled. The primary objective of a clinical study is usually to assess a product's effectiveness and safety based on the planned treatment regimen instead of the actual treatment received. The estimand using the treatment policy strategy, which collects and analyzes data regardless of the occurrence of intercurrent events, is usually utilized. In this article, we explain how missing data can be handled using the treatment policy strategy from the authors' viewpoint in connection with antihyperglycemic product development programs. The article discusses five statistical methods to impute missing data occurring after intercurrent events. All five methods are applied within the framework of the treatment policy strategy. The article compares the five methods via Markov Chain Monte Carlo simulations and showcases how three of these five methods have been applied to estimate the treatment effects published in the labels for three antihyperglycemic agents currently on the market. 相似文献

We consider a generalized leverage matrix useful for the identification of influential units and observations in linear mixed models and show how a decomposition of this matrix may be employed to identify high leverage points for both the marginal fitted values and the random effect component of the conditional fitted values. We illustrate the different uses of the two components of the decomposition with a simulated example as well as with a real data set. 相似文献

At the heart of this article is a structural approach to narrative, based on the work of Propp, Labov, van Dijk, Halliday,
and others. The article highlights the structural features of narrative—basically, the organization of the genre around the
semantic template actor-action-actor (syntactically rendered as subject-verb-object but where, in narrative, the subject is
typically a social actor and the verb a social action) and the modifiers of each element of this triplet, such as time and
space of action—and shows how to implement this structure in a computer environment and how to use this methodological tool
in socio-historical research (namely, the rise of Italian fascism, 1919–22). But, taking a cue from Halliday’s cover jacket
of his An Introduction to Functional Grammar, with its representation of a color circle, the paper takes the reader on an intellectual journey from Newton to Goethe—and
the quality versus quantity debate—to Goethe and Propp, to end, back home, with Simmel and Weber. 相似文献

Several bivariate beta distributions have been proposed in the literature. In particular, Olkin and Liu [A bivariate beta distribution. Statist Probab Lett. 2003;62(4):407–412] proposed a 3 parameter bivariate beta model which Arnold and Ng [Flexible bivariate beta distributions. J Multivariate Anal. 2011;102(8):1194–1202] extend to 5 and 8 parameter models. The 3 parameter model allows for only positive correlation, while the latter models can accommodate both positive and negative correlation. However, these come at the expense of a density that is mathematically intractable. The focus of this research is on Bayesian estimation for the 5 and 8 parameter models. Since the likelihood does not exist in closed form, we apply approximate Bayesian computation, a likelihood free approach. Simulation studies have been carried out for the 5 and 8 parameter cases under various priors and tolerance levels. We apply the 5 parameter model to a real data set by allowing the model to serve as a prior to correlated proportions of a bivariate beta binomial model. Results and comparisons are then discussed. 相似文献
