Abstract Recent research does not provide clear evidence that rural schools are inferior to urban schools. For example, one prominent study finds that students in rural schools perform less well than their urban counterparts, but other studies using the same national data set have reached divergent conclusions. The present study reassesses the issue using a time series approach to school performance. We investigate the effects of location on school‐level performance and improvement indicators between 1999 and 2003 using a sample of 1,111 Kentucky public schools nested in 170 school districts. Repeated‐observations HLM analysis reveals that rural schools achieve mean annual gains in performance that equal or better their urban counterparts. Furthermore, schools in some nonmetro locations perform on par with metro schools in between‐school baseline score comparisons. A simple answer to the question “Are rural schools inferior?” is not feasible, however, since standards for assessing school quality are changing as a consequence of education reform initiatives at the state and national levels. 相似文献

The paper points out that in dynamic games a player may be better-off if other players do not know his choice of strategy. That is, a player may benefit by not revealing (or not pre-determining) the choice of his action in an information set he (thereby) hopes will not be reached. He would be better-off by exercising his ``right to remain silent' if he believes –- as the empirical evidence shows –- that players display aversion to ``Knightian uncertainty'. In this case, a player who behaves strategically, may wish to avoid revealing his strategy. This is true under various interpretations of the notion of ``strategy profiles'. 相似文献

Conclusion Changes in the demographics of the work force and structural changes in the economy have played a key role in declining union
membership over time. Since these trends are anticipated to continue into the future, union attempts to stem the decline must
accept these changes as given and adapt in ways that allow membership to grow even as these shifts occur. Such a fundamental
reorientation of priorities will be difficult, but some signs suggest that unions may be taking preliminary steps in this
direction. Such change is vital to unions’ survival, both as a social movement and as a political institution.

The omission of important variables is a well‐known model specification issue in regression analysis and mixed linear models. The author considers longitudinal data models that are special cases of the mixed linear models; in particular, they are linear models of repeated observations on a subject. Models of omitted variables have origins in both the econometrics and biostatistics literatures. The author describes regression coefficient estimators that are robust to and that provide the basis for detecting the influence of certain types of omitted variables. New robust estimators and omitted variable tests are introduced and illustrated with a case study that investigates the determinants of tax liability. 相似文献

Canada continues to be a prominent immigrant and refugee‐receiving country in worldwide migration, resettlement, and search for refuge, yet there is a gap in our understanding of these newcomers’ views of the specific meanings of social support and their support needs and resources. The purpose of this study was to understand the meanings of social support for immigrants and refugees in Canada, and to explore the types and adequacy of formal supports. Individual interviews were conducted with 60 service providers and policymakers initially (Phase 1), and 120 immigrants and refugees (60 Chinese, 60 Somali) in the second phase. The implications of these findings were elicited in group interviews (Phase 3) of policy decision‐makers, advocates, service providers, and managers. This investigation revealed many interrelated challenges facing refugees and immigrants such as language difficulties, inadequate information on services, poor health, racism, needs for retraining, rejection of foreign qualifications, unemployment, social isolation, social insecurity, dwindling social networks, and family conflicts. The study also illuminated culturally and socio‐economically determined perceptions of social support and support‐seeking strategies. Limited personal resources and dwindling social networks are an impediment to coping with integration and settlement challenges. In many cases, newcomers’ efforts to seek help are thwarted by systemic obstacles. Newcomers experienced extensive unmet support needs, which service providers cannot adequately meet due to bureaucratic and resource constraints. Policies in various sectors that affect the lives of immigrants and refugees are inadequate for bridging their support deficiencies. These support gaps hinder the successful settlement and integration of newcomers. Policies and programs fostering culturally relevant support, and inter‐sectoral collaboration among organizations addressing the support needs of immigrants and refugees are timely. 相似文献

Using the word “gay” to refer to something that is “boring” is part of American slang, and heterosexual males commonly call one another a “fag.” The responses of 767 college students were analyzed to explore how this language relates to antigay bias. Results of multiple regression explained 14.8% of the variance for believing that “it's no big deal” to call someone a fag, and age, sex, major, and attitudes toward gay men were significant predictors. For the frequency of saying “that's so gay,” 17.5% of the variance was explained by age, sex, major, and friends’ attitudes toward sexual minorities. Implications for social work education and future research are discussed. 相似文献

Summary. Primary and metastatic brain tumour patients are treated with surgery, radiation therapy and chemotherapy. Such treatments often result in short- and long-term symptoms that impact cognitive, emotional and physical function. Therefore, understanding the transition of symptom burden over time is important for guiding treatment and follow-up of brain tumour patients with symptom-specific interventions. We describe the use of a hidden Markov model with person-specific random effects for the temporal pattern of symptom burden. Clinically relevant covariates are also incorporated in the analysis through the use of generalized linear models. 相似文献
