MEASURING REFLECTIVE SUPERVISION WITHIN HOME VISITING: CHANGES IN SUPERVISORS’ SELF‐PERCEPTION OVER TIME

Despite widespread belief in the early childhood field of the benefits of reflective supervision, there has been limited empirical evidence to support the effectiveness of reflective supervision for home visitors and the children and families they serve. The present study examined the psychometric properties of four adapted self‐report measures assessing supervisors’ reflective supervision capacities; the study also investigated whether these measures captured change in reflective capacity over time as supervisors participated in professional development activities focused on reflective supervision. Results from 33 participants (home visiting supervisors and program managers) suggested that three of the four measures demonstrated acceptable internal consistency, and these three measures were correlated with each other. Two of these measures also captured significant change over time. Finally, there was some evidence that those with less education demonstrated more substantial improvement in their reflective supervision capacities than did those with an advanced degree. Findings provide initial evidence for reliable, efficient, and cost‐effective supervisor self‐report measures that could be used in research and program evaluation to assess change in supervisor reflective capacity over time.     

MEDIATING ROLE OF MATERNAL SENSITIVITY: ENHANCING LANGUAGE DEVELOPMENT IN AT‐RISK FAMILIES

Home‐visiting programs have gained increasing importance in family‐centered prevention and intervention. However, few studies have examined the mechanisms underlying early intervention treatment effects. The goal of this study is to analyze the mediating role of maternal sensitivity in enhancing language development with the home‐visiting program Parents as Teachers (PAT). Data were collected and analyzed within the ongoing, long‐term ZEPPELIN study, a randomized controlled trial with 251 participating at‐risk families. Via longitudinal mediation analysis, we examined whether effects of the PAT on receptive and expressive language outcomes at 24 and 36 months were mediated by maternal sensitivity at 12 months. Within a moderated mediation framework, we investigated whether the level of family psychosocial stress affects this mediation. Results showed that intervention effects on language outcomes are mediated by maternal sensitivity—weakly and through specific pathways. Moderation and moderated mediation analyses indicated that effects of the PAT and also specific mediation effects increase with the level of psychosocial stress. Implications of the results for practice are discussed.     

肠促胰素对2型糖尿病胰岛功能的影响

胰岛β细胞功能障碍是2型糖尿病的重要发病机制之一,而现有治疗手段保护β细胞功能作用有限。最新的研究发现,肠促胰素不仅能够改善口细胞功能,而且能够避免低血糖、体重增加等不良反应,是治疗2型糖尿病的新途径。本文通过回顾公开发表的临床研究,对2型糖尿病口细胞功能、传统治疗及肠促胰素对β细胞功能的保护及延缓疾病进展作用进行了综...

采用语义启动研究范式,探讨傣族小学2、4、6年级汉语词汇和语音的语义通达特点。结果表明：1）对图片语义的提取存在学习年龄效应,2年级的反应时显著长于4、6年级;2）汉语词汇和语音都能显著促进图片语义的提取,但语音促进作用更明显;3）汉语词汇对图片语义提取的促进作用随年级的升高而增加,汉语语音的促进作用随年级的升高而减少。     

从佛教量论看翻译的实质及类型划分--兼论翻译理论中的不可译性问题

本文首先从佛教量论的角度对翻译的实质做出界定,指出翻译的实质是一种为他(社会性)的比量活动。根据翻译为他比量的实质,可以引导出翻译的两种类型：比知翻译和喻知翻译。比知翻译是具有事先直接约定性的语言传递活动;喻知翻译是没有事先直接约定的语言传递活动。根据从佛教量论对翻译实质和类型的规定,本文分析了不可译性问题,揭示出不可译性在认识论上的误区,指出不可译性是不可知论或怀疑论在翻译领域的显现。     

Correlations of glucose metabolism and structural damage to language function in aphasia

Studies of aphasic patients using [18F]fluorodeoxyglucose positron computed tomographs have shown areas of metabolic depression in the left hemisphere larger than the area of infarction noted on CT. To evaluate these metabolic differences in relationship to language abnormalities, 11 patients had metabolic scans, CT, and were administered the Boston Diagnostic Aphasia Battery and the Porch Index of Communicative Ability. Correlation analyses were computed between metabolic, CT, and language data. CT demonstrated reliable correlations of speaking, oral reading, and repetition to Wernicke' area, consistent with current anatomic language models, while metabolic data from areas posterior, inferior, and superior to the traditional Wernicke's area and the head of the caudate nucleus also had reliable correlations with aphasic language function. The utilization of both structural and metabolic brain measures may improve our understanding of the anatomy of language as related to aphasia.     

Comparison of the concurrent validity of Holland's theory for men and women in an enterprising occupation

This study examined the concurrent validity of Holland's theory for men and women employed in an enterprising occupation. Using Holland-theme scores obtained from both the Self-Directed Search (SDS) and the Strong-Campbell Interest Inventory (SCII), the degree of personality-environment correspondence and the relationships of personality type to job satisfaction were examined in a sample of 45 male and 43 female sales managers. In general, the findings suggested that, at least within an employed sample, Holland's theory is valid for women as well as for men. Using both the SDS and the SCII, women and men obtained their highest scores on the enterprising theme, and the mean E-theme scores of women were at least as high as were those of men. Significant sex differences on the Realistic, Artistic, and Social scales, found using SDS scores and SCII standard scores, were in the direction of generally-found sex differences. Both men and women were highly satisfied with their jobs, and moderate relationships between job satisfaction and enterprising and social scores were also found. While the results of this study suggest optimism regarding the theoretical and practical utility of Holland's theory for women as well as for men, differences in results as a function of different instruments and scoring methods suggest the need for further studies of this kind.     

Some further tests of the brief confinement effect and the SSDR account of flooding

Although brief confinement in novel or fearful places may occasionally produce flooding-like effects with regard to hastening avoidance response extinction, the results of the three experiments reported here indicate that this is not as robust a phenomenon as is flooding. Experiments 1 and 2 found that any tendency for a brief confinement effect to occur is likely to result from the use of a procedure where extinction is started on the grid floor as opposed to on the ledge of a jump-up box. Experiment 3 found no evidence at all that confinement in either a novel or a fearful place can hasten the extinction of a more well-learned jump-up response than that studied in previous experiments, even when the grids extinction procedure was used. Overall these results do not support the SSDR account of flooding, which has derived its chief support from experiments demonstrating a brief confinement effect.     

Performance of an unpleasant task: Effects of over- vs under-payment on perception of adequacy of rewards and task attractiveness

Subjects who came to an experiment expecting to receive a moderate amount of money for performing a task were then told, either before or after performing it, that their pay would be higher than, equal to, or less than they had expected. When the actual payment was announced after the task was performed, subjects' evaluations of the task increased with the amount they were paid; however, they estimated a higher rate of pay to be appropriate if they received either more or less than they expected than if they received what they expected. When the actual payment was announced before the task was performed (and before subjects made their decision to perform it), a different pattern emerged. Subjects rated the task more attractive when they were offered either more or less than the expected amount, while their judgments of the appropriateness of the pay offered increased with the amount of the offer. Implications of the results for incentive and dissonance theories as well as self-perception and equity theories are discussed.
