The study offers a development of the social technologies of “service” municipal administration. The consumers’ opinions should be taken into consideration when determining the nomenclature and standards of their provision, which include the quality parameters that the consumers consider important. In addition, “service” relations imply the assessment of consumer satisfaction with the services and the correction of services based on the results of the assessment. Since this interaction implies communication between the municipal administration body and service users, it is necessary to focus on communicative technologies that are capable of providing a full cycle of service development and improvement for young entrepreneurs. Communications should help determine the expectations associated with a service, raise awareness thereof, and involve young people in the decisions related to the provision of services. 相似文献

High-dimensional sparse modeling with censored survival data is of great practical importance, as exemplified by applications in high-throughput genomic data analysis. In this paper, we propose a class of regularization methods, integrating both the penalized empirical likelihood and pseudoscore approaches, for variable selection and estimation in sparse and high-dimensional additive hazards regression models. When the number of covariates grows with the sample size, we establish asymptotic properties of the resulting estimator and the oracle property of the proposed method. It is shown that the proposed estimator is more efficient than that obtained from the non-concave penalized likelihood approach in the literature. Based on a penalized empirical likelihood ratio statistic, we further develop a nonparametric likelihood approach for testing the linear hypothesis of regression coefficients and constructing confidence regions consequently. Simulation studies are carried out to evaluate the performance of the proposed methodology and also two real data sets are analyzed. 相似文献

Retaining engaged volunteers is crucial to many non-profit organizations. However, research on volunteer engagement is limited, and the distinction between job and organizational engagement in volunteers remains to be investigated. In this paper, we examine both organizational- and job-level engagement, and specifically, whether perceived organizational support would enhance volunteer engagement and associated attitudes. We surveyed 221 volunteers, and asked them about their perceptions of organizational support; their engagement with their volunteer job and the organization they volunteer for; satisfaction; commitment; and turnover intentions. Both organizational and job engagements had significant relationships with the attitudinal variables. However, we found that organizational rather than job engagement mediated the relationship between organizational support and volunteer satisfaction and commitment. While organizational engagement correlated with turnover intentions, neither job nor organizational engagement mediated the relationship between support and the intent to leave. Our findings advance the research on volunteer engagement, and highlight the importance of organizational engagement for this important, but too often overlooked, workforce. 相似文献

In drug treatment outcome literature, a focus on objective and socially desirable indicators of change (e.g. no drug use)
has predominated, while outcome indicators that are important for drug users themselves (e.g. quality of life, satisfaction
with treatment) have largely been neglected. Nonetheless, Quality of Life (QoL) has become an important concept to evaluate
effectiveness of treatment in mental health care research and disability studies. Given the almost exclusive focus on Health-related
Quality of Life (HRQOL) in substance abuse research and the neglect of clients’ perspectives in this field, we explore in
this study the concept of QoL as perceived by drug users. Focus group discussions (n = 9) were organised in various treatment settings and community services for drug users in the region of Ghent, Belgium to
identify important dimensions of QoL and their interpretation by drug users. Data were clustered and analysed based on the
theoretical framework of Robert Schalock (Quality of life. Volume 1: Conceptualization and measurement, 1996). The domains
‘personal relationships’, ‘social inclusion’ and ‘self-determination’ were discussed most frequently by the participants.
They stressed the importance of a supportive social network in particular. It can be concluded that QoL is not primarily associated
by drug users with health and it involves much more than the aspects typically represented in measures of HRQOL. 相似文献

This paper proposes a functional connectivity approach, inspired by brain imaging literature, to model cross-sectional dependence.
Using a varying parameter framework, the model allows correlation patterns to arise from complex economic or social relations
rather than being simply functions of economic or geographic distances between locations. It nests the conventional spatial
and factor model approaches as special cases. A Bayesian Markov Chain Monte Carlo method implements this approach. A small
scale Monte Carlo study is conducted to evaluate the performance of this approach in finite samples, which outperforms both
a spatial model and a factor model. We apply the functional connectivity approach to estimate a hedonic housing price model
for Paris using housing transactions over the period 1990–2003. It allows us to get more information about complex spatial
connections and appears more suitable to capture the cross-sectional dependence than the conventional methods. 相似文献

We describe a first experiment on whether product complexity affects competition and consumers in retail markets. We are unable
to detect a significant effect of product complexity on prices, except insofar as the demand elasticity for complex products
is higher. However, there is qualified evidence that complex products have the potential to induce consumers to buy more than
they would otherwise. In this sense, consumer exploitability in quantities cannot be ruled out. We also find evidence for
shaping effects: consumers’ preferences are shaped by past experience with prices, and firms may in principle exploit this
to sell more. 相似文献

A Diamond-Stiglitz approach to the demand for self-protection 总被引:1,自引:0,他引:1
The existing research concerning the relationship between risk aversion and prudence and the demand for self-protection assumes
that the loss variable follows a Bernoulli distribution, and that changes in the level of self-protection are mean preserving.
The analysis here replaces these two very strong conditions with ones which are more general. When doing this, the method
of analysis is also significantly modified. This modification includes representing a change in the level of self-protection
using the procedure developed by Diamond and Stiglitz (Journal of Economic Theory 8:337-360, 1974) for representing a change in risk. This alternate representation allows the existing findings to be generalized considerably,
and also simplifies the analysis. 相似文献

This study explored the extent to which private regard and religiosity beliefs serve as protective factors for school bonding among African American and Caribbean black adolescents who experience racial discrimination in school. Findings are drawn from a nationally representative sample of (n = 810) African American and (n = 360) Caribbean black adolescents (52% girls) aged 13–17 (Mage = 15, SD = 1.42) years. Results suggest that perceiving racial discrimination from teachers was associated with lower levels of school bonding for African American and Caribbean black adolescents. For African American adolescents, perceiving more racial discrimination from teachers and reporting lower private regard beliefs was associated with less school bonding. The findings for Caribbean black adolescents revealed that endorsing moderate levels of religiosity and perceiving higher rates of teacher discrimination was associated with less school bonding. The developmental significance and implications for future research are discussed. 相似文献
