当前我国的信用现状不能令人满意,存在诸多信用失范现象,这导致了现时信用环境恶劣,也阻碍了我国社会主义市场经济的健康发展。法学界也对此予以关注,并试图以民法典立法确立信用权为人格权的路径进行规范,并且当前几个建议稿对信用权的规定有很大不同,皆有不完善之处。因此,应当进行整合,在未来民法典中对信用权作出完善的规制,构建我国的完整信用权制度,形成完善的信用体系。  相似文献

Within the professional community, a vast number of sexual abuse treatment programs have emerged to meet the needs of victims and their families. Significant variations among these programs can be observed due to differences in philosophy, system context, client focus, problem definition, and the treatment strategy adopted. Unfortunately, little comparative information is available regarding the operation of different programs and, more importantly, their relative treatment effectiveness. This article presents the findings from a nationwide survey of 553 sexual abuse treatment programs. The survey focused on program context, client, and service characteristics. Overall it was found that most programs are affiliated with a larger public or private agency, focus on treating victims, and rely on a combination of individual, family, dyad, and group therapy approaches.  相似文献

Objective: To analyze the association between attitudes of filial responsibility and adult child caregivers’ behaviors in the Southern Region of Brazil.

Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.

Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).

Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed.  相似文献

Use of nonanatomical dolls in the sexual abuse interview   总被引:2,自引:0,他引:2  
Controversy exists regarding use of anatomically detailed dolls in child sexual abuse evaluations because of concerns that such dolls may provoke false positive demonstrations of sexually explicit behavior. This study shows that children referred for medical evaluation of sexual abuse will use sexually explicit behavior to demonstrate what has happened to them with nonanatomical dolls as frequently as when they are interviewed with anatomically detailed ones. Over a two-year period, 136 children (aged 24 months to 10 years) were interviewed by the same pediatric interviewer. During the first year sexually anatomically detailed dolls (SAD) were used, and in the subsequent year nonanatomic dolls (NAD) were used. Data was analyzed according to age, sex, and demonstration of sexually explicit behavior. There were 67 children in the NAD group and 69 in the SAD group. Of the NAD group, 72% showed sexually explicit behavior compared to 68% in the SAD group. Comparisons using chi-square analysis revealed no significant differences between NAD and SAD. Results indicated that in the sexual abuse interview setting, use of sexually detailed dolls did not increase children's use of sexually explicit behavior to describe what had happened to them when compared to use of nonanatomical dolls, and that use of either type of doll provides similar information in the interview setting.  相似文献

Toddlers displaying extremely inhibited behavior may be at risk for becoming socially withdrawn. However, behavioral inhibition may be a multifaceted characteristic, and its concurrent relation to toddler wariness with peers has not been examined. In this study, 108 toddlers (54 females) and their mothers were observed in novel situations involving unfamiliar settings, adults, and peers. Vagal tone, temperament, separation-reunion behavior, and maternal oversolicitousness also were assessed. There was little consistency of inhibited behavior across the 3 situations. Consistently inhibited toddlers had fearful temperaments, showed distress following maternal separation, and had mothers who were warm and controlling but unresponsive to children's cues during interaction. Toddlers with highly fearful temperaments and highly oversolicitous mothers were the most inhibited across contexts.  相似文献

本研究的目的在于以分析教师批判性思维倾向(Teacher Critical Thinking)的结构为基础,制订教师批判性思维倾向的测量工具。原始问卷根据台湾学者朱苑瑜、叶玉珠编制完成的《批判性思考倾向量表》及教师批判性思维倾向的理论定义而构造。489位中小学教师参加了测验。要求被试在6点量表上评定问卷的每一个条目是否适合描述他们自己,“1”代表非常同意,“6”代表非常不同意。测验结果得到了一个由12个条目构成的四因素结构的教师批判性思维倾向量表,该因素解释总变异的74.2%,量表平均分为27.12,标准差为10.98,无显著性性别差异(t=.336,P=.737)。统计分析还表明:该量表具有较好的内部一致性信度(a=.9496)和折半信度(r=.9384)。本量表适合在中小学教师中使用,稳定性较强,项目较少,简便易行。  相似文献

In human infancy, 2 criteria for intentional communication are (a) persistence in and (b) elaboration of communication when initial attempts to communicate fail. Twenty-nine chimpanzees (Pan troglodytes) were presented with both desirable (a banana) and undesirable food (commercial primate chow). Three conditions were administered: (a) the banana was delivered (successful communication), (b) half of the banana was delivered (partially successful communication), and (c) the chow was delivered (failed communication). The chimpanzees exhibited persistence in and elaboration of their communication in every condition except when the banana was delivered. Thus, their communication was about a specific item, demonstrating that both intentionality and nonverbal reference are capacities shared by humans with our nearest living relatives, the great apes.  相似文献

The initial purpose of this study was to determine how counselors used information yielded by multifactor intelligence tests. Data from questionnaires sent to secondary school counselors in two states, however, revealed enormous percentages of nonclassifiable responses regarding these tests. The proportion of nonclassifiable responses varied from 38 percent on questions concerning where different scores were recorded to 70 percent on questions concerning which IQ scores were most and least predictive of scholastic achievement. Consequently, the study concentrated on the reasons for the large number of unusable responses. The findings seemed to indicate a tendency on the part of counselor educators to downgrade the importance of accurate test interpretation.  相似文献
