This paper analyzes citizens’ perception of past environmental damage and liability through the estimation of willingness to pay for the implementation of decontamination and land rehabilitation of the damaged site. The paper takes the Russian Federation as a case of country in transition and focuses on Kemerovo region as one of the most affected regions in the country. The major analytical tool employed in the study is choice experiment, data for which was collected through a household survey. Primary conclusion of the analysis is that citizens' willingness to financially support the implementation of environmental quality improvement projects is not high though individuals in the studied area express high level of concern over the issue in focus.  相似文献

Survey statisticians make use of auxiliary information to improve estimates. One important example is calibration estimation, which constructs new weights that match benchmark constraints on auxiliary variables while remaining “close” to the design weights. Multiple-frame surveys are increasingly used by statistical agencies and private organizations to reduce sampling costs and/or avoid frame undercoverage errors. Several ways of combining estimates derived from such frames have been proposed elsewhere; in this paper, we extend the calibration paradigm, previously used for single-frame surveys, to calculate the total value of a variable of interest in a dual-frame survey. Calibration is a general tool that allows to include auxiliary information from two frames. It also incorporates, as a special case, certain dual-frame estimators that have been proposed previously. The theoretical properties of our class of estimators are derived and discussed, and simulation studies conducted to compare the efficiency of the procedure, using different sets of auxiliary variables. Finally, the proposed methodology is applied to real data obtained from the Barometer of Culture of Andalusia survey.  相似文献

This paper reviews global and multiple tests for the combination ofn hypotheses using the orderedp-values of then individual tests. In 1987, Röhmel and Streitberg presented a general method to construct global level α tests based on orderedp-values when there exists no prior knowledge regarding the joint distribution of the corresponding test statistics. In the case of independent test statistics, construction of global tests is available by means of recursive formulae presented by Bicher (1989), Kornatz (1994) and Finner and Roters (1994). Multiple test procedures can be developed by applying the closed test principle using these global tests as building blocks. Liu (1996) proposed representing closed tests by means of “critical matrices” which contain the critical values of the global tests. Within the framework of these theoretical concepts, well-known global tests and multiple test procedures are classified and the relationships between the different tests are characterised.  相似文献

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders, uses the term “remission” to describe the reduction of depressive symptoms. This paper argues that by categorizing someone who no longer has depressive symptoms as “in remission,” that person may feel indefinitely tied to his or her diagnosis. Considering the unfortunate stigma associated with mental illness, permanent linkage to diagnosis through records and professional memory may cause individuals to internalize pathology. In fact, the language of the diagnosis can affect self-perception in sensitive souls for a lifetime. As an implication for practice, we propose that cognitive and narrative therapy approaches, mood-memoirs, and use of metaphor present alternative uses of language that can reduce power imbalances between clinicians and clients, providing a bridge to healing.  相似文献

Educated Caring: The Emergence of Professional Identity Among Nurses   总被引:1,自引:0,他引:1  
This article examines the formation of occupational identity in a nursing program. The normative and ideological dimensions of this process are revealed in the program’s goals and the views of educators and students through qualitative data from observations and 30 in-depth interviews. Educators seek to socialize students toward professionalism to raise the occupation’s status by emphasizing the scientific and technical basis of nursing. Yet students uphold a gendered discourse by identifying a normative dimension of caring as central to their occupational identity. The dilemma between professionalism and caring is reconciled as students construct an occupational identity based on “educated caring,” where these two dimensions are equally valuable and significant.

This qualitative study examined the experiences of alternative school students as they participated in a mindfulness skills program. A 7-month school-based mindfulness skills program was integrated into the Grade 10 curriculum for high school students (N = 19; 10 boys and 9 girls, ages 15–17). Students engaged in mindfulness practices twice weekly during class time. Students practiced breath awareness, and seated, walking, and lying mindfulness meditation during the course of the program. Students completed initial and final questionnaires about their experiences as well as written journal entries based on their experiences in the program. At the completion of the program, 14 of the 19 program completers were interviewed (6 boys and 8 girls). Data analysis yielded two broad areas of perceived benefits of participation in the mindfulness skills program: intrapersonal benefits and interpersonal benefits. Intrapersonal benefits included themes of self-awareness and self-regulation (including cognition, emotions, and behavior). Interpersonal benefits included themes of building relationships (with peers, family members, and teachers) and learning to trust. These findings may be useful when planning school-based mindfulness programs and may serve as a guide for researchers studying mindfulness practices for youth.  相似文献

The purpose of this study was to determine the number of residents requiring corrective lenses in a youth detention center for juveniles from 12 to 18 years old over a 2-year period. A greater number of adolescents incarcerated for criminal activity in a detention center had uncorrected refractive errors (34.87 %) as compared to a comparable population in the public school system (22 %). The prevalence of significant refractive errors among incarcerated adolescents in this study is significantly higher than has been reported previously. The current study found a refractive error rate of almost 35 %. This difference can be explained by a number of factors in their social environments and identifies an area for potential intervention to reduce antisocial behavior in this population.  相似文献

Optimum experimental design theory has recently been extended for parameter estimation in copula models. The use of these models allows one to gain in flexibility by considering the model parameter set split into marginal and dependence parameters. However, this separation also leads to the natural issue of estimating only a subset of all model parameters. In this work, we treat this problem with the application of the \(D_s\)-optimality to copula models. First, we provide an extension of the corresponding equivalence theory. Then, we analyze a wide range of flexible copula models to highlight the usefulness of \(D_s\)-optimality in many possible scenarios. Finally, we discuss how the usage of the introduced design criterion also relates to the more general issue of copula selection and optimal design for model discrimination.  相似文献

Much of the discussion of state steering of service delivery networks to encourage collaboration at the local level has been theoretical. This study builds on this analysis systematically to assess the relationship between meta-governance tools of central government steering and the extent of local collaboration, using the case of homelessness services in England. Contrary to the pessimist expectations of some contemporary theory, central government funding tools and facilitating the transfer of best practice encourages collaboration. However, simple information provision and authority based tools are only partially effective, risking tokenistic compliance. Authority tools are more effective when combined with other tools.
