The U.S. electric power sector has experienced a substantial shift of the generation mix since the turn of the century, moving from heavy reliance on coal‐powered generation to one drawing more from natural gas and, more recently, renewables. This transition has been forged by a mix of macroeconomic factors (recession and recovery); technological breakthroughs (horizontal drilling coupled with hydraulic fracturing; improvements in natural gas plant efficiency); clean energy policies at federal, state, and local levels of government; and private sector demands for carbon‐free energy sources. These factors have combined to reduce carbon emissions from electric power generation substantially this century. In this article we examine the extent of this transition, its causes, as well as the distinct American institutional factors steering it, including energy and environmental federalism, electoral politics, and the political economy of clean energy policy enactment and resistance. 相似文献

In the present studies, we aimed to show that the perceived procedural fairness of societal actors’ multicultural decisions promotes ethnic minority members’ societal identification. These enhanced identification levels, in turn, contribute to better psychological health and well-being. Firstly, a vignette study in a sample of African Americans explored the effect of procedural fairness climate on identification. The second and third studies used self-report questionnaires. Study 2 consisted of a sample of sojourners in a university context, Study 3 analyzed online data through an African American sample. The studies provided evidence for the effect of procedural fairness climate on increased societal identification, which in turn mediates the fairness effect on increased well-being and psychological health. Societal actors can use procedural fairness to increase well-being when making decisions that involve ethnic minorities.
The author wrote an article, “Parental Alienation and Misinformation Proliferation,” for this Special Issue of Family Court Review, which is devoted to various aspects of parental alienation (PA). This short article is a response to the article by Milchman, Geffner, and Meier, which discussed my article and other contributions to the Special Issue. All of these articles represent an attempt by the Editors of the Special Issue to promote “dialogue” among writers who have different perspectives regarding parental alienation. In my view, this is a misguided endeavor, since the publication of cascading criminations, recriminations, and re‐recriminations simply creates confusion and consternation for the readers of Family Court Review. This new article offers an alternative approach for creating constructive dialogue among PA‐promoters and PA‐detractors, that is, convene a face‐to‐face discussion of these individuals and encourage them to write an article together in which they jointly explain their various perspectives regarding PA. 相似文献
Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal
reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model
of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of
each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’
behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing
behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect
on informant reports of problem behavior has not been previously reported. 相似文献
Self-determination theory emphasizes the importance of school-based autonomy and belongingness to academic achievement and psychological adjustment,
and the theory posits a model in which engagement in school mediates the influence of autonomy and belongingness on these
outcomes. To date, this model has only been evaluated on academic outcomes. Utilizing short-term longitudinal data (5-month
timeframe) from a set of secondary schools in the rural Midwest (N = 283, M age = 15.3, 51.9% male, 86.2% White), we extend the model to include a measure of positive adjustment (i.e., hope). We also
find a direct link between peer-related belongingness (i.e., peer support) and positive adjustment that is not mediated by
engagement in school. A reciprocal relationship between academic autonomy, teacher-related belongingness (i.e., teacher support)
and engagement in learning is supported, but this reciprocal relationship does not extend to peer-related belongingness. The
implications of these findings for secondary schools are discussed.
The aim of this five-wave longitudinal study was to investigate the relationship between anxiety and adolescent identity development.
Participants were 1,313 adolescents who annually completed measures of anxiety and identity. Growth Mixture Modeling (GMM)
analyses demonstrated that the adolescent population was best typified by two latent growth trajectory classes: a low anxiety class (n = 1,199) characterized by a low initial level of anxiety that decreased over time and a high anxiety class (n = 114) characterized by a higher initial level of anxiety that increased over time. To answer our research question, we tested
a model in which the anxiety classes predicted initial levels and rates of change of three identity dimensions: commitment,
in-depth exploration, and reconsideration of commitment. Findings indicated that the high anxiety adolescents displayed a
more troublesome identity development than their low anxiety peers, since their commitments became weaker with age, and they
reconsidered them intensively.
