This memoir provides the personal story of a tenured poet who initially walked the picket line during the 1990 University of Bridgeport faculty strike. During the strike's second week, he made the difficult decision to cross the picket line of a union he helped create seventeen years earlier. He continually relives his strike experience.  相似文献

In recent years, behavior analysts have lamented a disconnection between applied research and practice. In their book, Treatments That Work: Empirically Supported Strategies for Managing Child Behavior Problems, Christophersen and Mortweet (2001) have attempted to bridge this gap for medical and behavioral health providers alike by describing empirically supported treatments, derived from behavior therapy and its application, that are specifically designed for challenging problems commonly seen in typical children. The book is clearly intended for both primary care physicians and behavior therapists, and in this article, we review the extent to which the book meets the needs of each. Discussion centers on the extent to which the book can meet the need for both technical precision and conceptual breadth in training of behavior therapists. We conclude that, in making explicit the connections between research and practice, the authors have provided a useful clinical teaching tool and have also raised important questions about how best to establish collaborative relationships with physicians and promote the use of behavioral technology in primary care.  相似文献

This article is devoted to theexploration of some trends in gender studies incontemporary Russia and is based on ourresearch and teaching in the field over thecourse of seven years. The main concepts ofgender research – gender, feminism,women's subjectivity – were introduced to theRussian public early in 1990s; Russian genderstudies began to develop as a whole due to theapplication of Western concepts and theories.The article examines the growth of genderstudies over the last 10 years, contextualdifferences as well as theoretical approachesin Russian gender studies as these have arisenin the context of the `Russia – West'dichotomy.  相似文献

In recent years, researchers have identified that coping strategies are an important contributor to an individual’s life satisfaction and ability to manage stress. The positive relationship between religious copings, specifically, with physical and mental health has also been identified in some studies. Spirituality and religion have been discussed rigorously in research, but very few studies exist on religious coping. The aim of this study was to determine the relationship between religious coping methods (i.e., positive and negative religious coping) and self-care behaviors in Iranian medical students. This study used a cross-sectional design of 335 randomly selected students from Mazandaran University of Medical Sciences, Iran. A data collection tool comprised of the standard questionnaire of religious coping methods and questionnaire of self-care behaviors assessment was utilized. Data were analyzed using a two-sample t test assuming equal variances. Adjusted linear regression was used to evaluate the independent association of religious copings with self-care. Adjusted linear regression model indicated an independent significant association between positive (b = 4.616, 95% CI 4.234–4.999) and negative (b = ?3.726, 95% CI ?4.311 to ?3.141) religious coping with self-care behaviors. Findings showed a linear relationship between religious coping and self-care behaviors. Further research with larger sample sizes in diverse populations is recommended.  相似文献

Reading comprehension assessment should rely on valid instruments that enable adequate conclusions to be taken regarding students' reading comprehension performance. In this article, two studies were conducted to collect validity evidence for the vertically scaled forms of two Tests of Reading Comprehension for Portuguese elementary school students in the second to fourth grades, one with narrative texts (TRC‐n) and another with expository ones (TRC‐e). Two samples of 950 and 990 students participated in Study 1, the study of the dimensionality of the TRC‐n and TRC‐e forms, respectively. Confirmatory factor analyses provided evidence of an acceptable fit for the one‐factor solution for all test forms. Study 2 included 218 students to collect criterion‐related validity. The scores obtained in each of the test forms were significantly correlated with the ones obtained in other reading comprehension measures and with the results obtained in oral reading fluency, vocabulary and working memory tests. Evidence suggests that the test forms are valid measures of reading comprehension.  相似文献

Objective: The purpose of this study was to examine the relationships between medical mistrust and trust and to determine if these measures differentially predict antiretroviral therapy (ART) medication adherence for African-American adults living with HIV.

Design: A total of 458 HIV positive African-Americans completed a cross-sectional survey.

Main Outcome Measures: Self-reported ART adherence was collected using the visual-analog scale. The Beliefs About Medicines Questionnaire was used to assess medication necessity and concern beliefs.

Results: All measures of medical mistrust and trust were significantly negatively correlated, ranging from r = ?.339 to ?.504. Race-based medical mistrust significantly predicted medication necessity and concern beliefs, whereas general medical mistrust only significantly predicted medication concerns. Both measures of trust significantly predicted medication necessity beliefs and medication concerns. Higher levels of race-based medical mistrust predicted lower medication adherence, whereas, neither trust in own physician nor trust in health care provider significantly predicted medication adherence. However, trust in own physician significantly predicted medication necessity beliefs, which predicted medication adherence.

Conclusion: Trust and mistrust are not simply opposites of one another. These findings provide evidence for the complexity of understanding the relationship between health care trust, mistrust and patient-related health beliefs and behaviours.  相似文献

Cognitive Behavioral Therapy (CBT), Rational Emotive Behavior Therapy (REBT) and Metacognitive Therapy (MCT) models show both similarities and differences in conceptualizing anxiety. This work assumes that REBT’s irrational and MCT’s metacognitive beliefs play a mediation role while CBT’s disorder specific content beliefs act as triggers. This hypothesis is tested using a regression model in which metacognitive and irrational beliefs play a mediation role while content disorder beliefs are independent variables. This paper applied this model to generalized anxiety disorder (GAD), a psychiatric diagnosis in which anxiety is the major feature. In GAD, the specific content beliefs are negative problem orientation and intolerance of uncertainty. Therefore, 149 non clinical subjects completed 4 self-report questionnaires: the Negative Orientation to the Problems Questionnaire and the Intolerance of Uncertainty Scale as measures for content cognitive beliefs, the Attitudes and Beliefs Scale for irrational beliefs, and the Metacognitive Questionnaire 30 Items Version for metacognitive beliefs. The generalized anxiety disorder questionnaire was chosen in order to measure anxiety as dependent variable. Regression analyses confirmed that irrational and metacognitive beliefs mediate the relation between cognitive content beliefs and GAD. We clinically interpret mediation as a second level regulation.  相似文献

Research consistently indicates that children with sickle cell disease (SCD) face multiple risk factors for neurocognitive impairment. Despite this, no empirical research to date has examined the impact of neurocognitive functioning on quality of life for this pediatric group. Thus, the current study aims to examine the relationship between executive functioning and quality of life in a sample of children with SCD and further explore psychosocial and family/caregiver resources as moderators of this relationship. A total of 45 children with SCD aged 8 to 16 years and their caregivers completed measures of quality of life, behavioral ratings of executive functioning, and psychosocial functioning. Hierarchical linear regression models were utilized to determine the impact of executive functioning on quality of life and further test the interaction effects of proposed moderating variables. Controlling for age, pain, and socioeconomic status (SES), executive functioning was found to significantly predict child- and parent-reported quality of life among youth with SCD. Psychosocial resources of the primary caregiver or family was not found to moderate the relationship between executive functioning and quality of life. These results provide the first empirical evidence that lower executive skills negatively predict quality of life for children with SCD, supporting clinical and research efforts which aim to establish efficacious interventions that target cognitive decrements within this pediatric population.  相似文献
