This article considers the two-way error components model (ECM) estimation of seemingly unrelated regressions (SUR) on unbalanced panel by generalized least squares (GLS). As suggested by Biørn (2004) for the one-way case, in order to use the standard results for the balanced case the individuals are arranged in groups according to the number of times they are observed. Thus, the GLS estimator can be interpreted as a matrix weighted average of the group specific GLS estimators with weights equal to the inverse of their respective covariance matrices. 相似文献

Abstract Twelve-hour shift schedules are becoming increasingly popular. The present study was designed to investigate the attitudes of nurses, their priorities with respect to working time and other aspects of the working conditions, and to analyse the conditions leading to a diminished satisfaction with the shift schedule and to aspirations for a change of schedule. Questionnaires were returned by 880 nurses (78% return rate) from 12 hospitals. A total of 65% worked 12-h shifts and 35% worked 8-h shifts. A considerable proportion of both groups showed a low satisfaction with their schedule and a desire to change the schedule (44% of those working 12-h shifts, 47% of those working 8-h shifts). Concerning effects of the shift schedule on work strain, continuity of service, health, family and leisure time, 8-h shifts were rated more favourably, especially by those working these shifts, but also by nurses working 12-h systems, with the exception of effects on leisure time and to some extent also on continuity of service and on family. Effects of the shift schedule on social responsibilities and leisure time activities turned out to be a major moderating variable in both groups with respect to schedule satisfaction and attitudes towards a change of schedule. Apparently neither type of shift system, traditional 12-h shift rosters or rotating 8-h shifts, is very appealing to the nurses. A stronger relationship between social consequences and health state in nurses working 12-h shifts indicates that in this group negative effects on family and leisure time might be due to an increased need for recuperation, which reduces effective leisure time. 相似文献

In a national sample of the Italian population, surveyed four times between October 2002 and January 2007 (N = 2,008), we performed a multilevel longitudinal study aimed at predicting the increase in crime risk perception as a function of three families of independent variables, respectively lying at the within individual level (direct victimization and indirect victimization), at the between-individuals level (being a woman, being an older person, being a poorly educated person and size of area of residence) and at the ecological level (county’s crime rate, unemployment rate and immigration rate). Direct and indirect victimization, being a woman, being an older person, living in a large town and in a context characterized by high crime and unemployment rates positively influenced the change in crime risk perception, while the other individual and ecological predictors we used in our predictive model did not. Strengths, limitations, implications and future developments of this research are discussed. 相似文献

An abundant literature studies the political thought of ordinary citizens qualitatively, but cross-national comparative studies are rare. To begin identifying cultural differences, this article focuses on the U.S. and Argentina, two countries that are opposite in many respects, while homogenizing the age, family situation, income, and metropolitan residence of the respondents. On one hand, the analysis shows two elements (that we call ideologemes) common to both countries: the vision of the public sphere of mothers who have experienced downward social mobility, and the recurrent reference to the breaking of a previously extant social covenant. On the other hand, it shows differences in a basic axis of discursive organization: In Argentina, personal experience is tied to political events and historicized, while in the U.S., discourses about society are predominantly articulated in terms of spatial categories. 相似文献

In Canada, there are long waiting lists of adopted persons and birthparents seeking information or actual reunions. In the province of Quebec, the government authorized a pilot project, involving a fee-for-service program and use of contract social workers to supplement agency staff as intermediaries in the reunion process. This article reports on the project's evaluation and provides birth-parents' and adoptees' responses to reunion. A survey of clients who used this service found a high level of satisfaction. There were, however, some significant differences between birthparents and adoptees as well as between those who were searching and those found. 相似文献

ABSTRACTEnvironmental data is typically indexed in space and time. This work deals with modelling spatio-temporal air quality data, when multiple measurements are available for each space-time point. Typically this situation arises when different measurements referring to several response variables are observed in each space-time point, for example, different pollutants or size resolved data on particular matter. Nonetheless, such a kind of data also arises when using a mobile monitoring station moving along a path for a certain period of time. In this case, each spatio-temporal point has a number of measurements referring to the response variable observed several times over different locations in a close neighbourhood of the space-time point. We deal with this type of data within a hierarchical Bayesian framework, in which observed measurements are modelled in the first stage of the hierarchy, while the unobserved spatio-temporal process is considered in the following stages. The final model is very flexible and includes autoregressive terms in time, different structures for the variance-covariance matrix of the errors, and can manage covariates available at different space-time resolutions. This approach is motivated by the availability of data on urban pollution dynamics: fast measures of gases and size resolved particulate matter have been collected using an Optical Particle Counter located on a cabin of a public conveyance that moves on a monorail on a line transect of a town. Urban microclimate information is also available and included in the model. Simulation studies are conducted to evaluate the performance of the proposed model over existing alternatives that do not model data over the first stage of the hierarchy. 相似文献

Scholars have sought various ways to find out how financial performance of the firm can be affected by its business model (BM). However, to date academic literature has focused attention on the “firm” as a unit of analysis without clearly defining the boundaries of the reporting entity to which the BMs refer. The aim of this paper is to investigate what are the boundaries of the BM of the affiliated-group companies and how the degree of independence of BMs is measured within the business group. The contribution of the paper is in using the BM concept to expound and criticise the assumptions in economic analysis and accounting standards that groups of companies are economic units that optimise economic income of the group as a whole and that the financial statements of individual subsidiaries, sub-groups and the group as a whole report the value generated by the group. 相似文献

The purpose of this paper is to provide a critical analysis of the impact of the privatisation of social security on Chile's economy and society. The paper also includes a brief discussion of Chile's current economic problems, and suggestions for integrating the social security system into the future development of the country. Its central argument is that social security should be able to provide adequate benefits not only to a privileged group of people, but to the entire society. In the case of Chile, the privatised system has created new sources of inequities, reduced the population coverage, and it has had a limited impact on economic development. 相似文献
