The Continuation of Perpetrator Behaviors that Influence Perceptions of Sexual Harassment

This study was designed to investigate sexual harassment perceptions based on continuation of unwanted sexual attention following victim resistance. Participants were 504 undergraduates who responded to statements regarding a sexual harassment scenario, in which the perpetrator continued or discontinued attention, which varied in severity according to nonphysical, physical, or restraint contact. Results showed that continued attention and any type of physical contact strengthened harassment perceptions, although men’s perceptions were weaker unless restraint was present. No sex differences were observed in the restraint condition. Women had stronger perceptions than men did in the physical condition, but showed a non-significant trend toward stronger perceptions in the nonphysical condition. Findings suggest that continuation following resistance may clarify for observers that harassment is occurring. Conceptualizations of harassment severity are suggested.     

胰岛素抵抗与非酒精性脂肪性肝病

非酒精性脂肪性肝病是一种以肝细胞脂肪变性和脂肪贮积为病理特征但无过量饮酒史的临床综合征。肥胖、2型糖尿病和高脂血症被认为是非酒精性脂肪性肝病的重要危险因素。有研究表明胰岛素抵抗与非酒精性脂肪性肝病密切相关。脂质代谢异常、氧应激反应、瘦素、脂联素等与胰岛素抵抗的发生有相互作用,也影响着非酒精性脂肪肝病的发生发展。胰岛素抵抗在非酒精性脂肪性肝病发病机制上的作用以及与胰岛素抵抗相关的发病因素值得关注。通过体育锻炼与控制饮食热量逐渐减轻体重,并配合血糖及血脂的控制对非酒精性脂肪性肝病患者十分重要。     

幽门螺杆菌感染治疗新进展

在中国幽门螺杆菌(Helicobacter pylori,Hp)有非常高的感染率,国人感染率约55%,所以Hp感染处理中的临床问题是目前Hp研究领域中的重点课题,Hp感染治疗中的重要问题主要包括以下几方面:(1)哪些病人应该治疗?(治疗适应证问题);(2)如何治疗?(治疗方案问题);(3)如何避免或克服Hp对抗生素的耐药性问题?Hp对抗生素的耐药是Hp根除失败的主要原因,所以本文还要重点讨论Hp对抗生素的耐药牲,Hp根除失败的补救治疗及其治疗研究进展。     

The Persistence-Strengthening Effects of DRA: An Illustration of Bidirectional Translational Research

We summarize a series of bidirectional research studies that demonstrate the persistence-strengthening effects of differential reinforcement of alternative behavior on problem behavior. We model a possible solution to this problem with rats followed by replication with a human clinical population. The importance of coordinated basic and applied research to stimulate new behavioral technologies is emphasized.     

二甲双胍对糖尿病大鼠脂联素的影响

二甲双胍能够改善胰岛素抵抗,而脂联素与胰岛素抵抗密切相关,因此本研究通过建立糖尿病大鼠模型,并给予二甲双胍治疗,观察胰岛素抵抗和脂联素的变化,研究结果显示二甲双胍的治疗改善胰岛素抵抗的同时,也增加了血清和组织中脂联素的表达,提示二甲双胍改善胰岛素抵抗的机制之一可能是通过增加脂联素的表达而获益。     

RESISTANCE TO CHANGE AND FREQUENCY OF RESPONSE‐DEPENDENT STIMULI UNCORRELATED WITH REINFORCEMENT

Stimuli uncorrelated with reinforcement have been shown to enhance response rates and resistance to disruption; however, the effects of different rates of stimulus presentations have not been assessed. In two experiments, we assessed the effects of adding different rates of response‐dependent brief stimuli uncorrelated with primary reinforcement on relative response rates and resistance to change. In both experiments, pigeons responded on variable‐interval 60‐s schedules of food reinforcement in two components of a multiple schedule, and brief response‐dependent keylight‐color changes were added to one or both components. Although relative response rates were not systematically affected in either experiment, relative resistance to presession feeding and extinction were. In Experiment 1, adding stimuli on a variable‐interval schedule to one component of a multiple schedule either at a low rate (1 per min) for one group or at a high rate (4 per min) for another group similarly increased resistance to disruption in the components with added stimuli. When high and low rates of stimuli were presented across components (i.e., within subjects) in Experiment 2, however, relative resistance to disruption was greater in the component presenting stimuli at a lower rate. These results suggest that stimuli uncorrelated with food reinforcement do not strengthen responding in the same way as primary reinforcers.     

Discovering Jesus Anew

In light of the political and ritual abuse of religion in India today, this article underlines the importance of Christian women’s engagement with women of all faiths to resist discrimination and violence. The Indian Christian Women’s Movement draws on Jesus’ liberative practice and teaching as women find creative and subversive ways to strengthen Christian women’s solidarity with women of other faiths. While all faith traditions carry embedded patriarchal biases that have been used to legitimize the second-class status of women, they also have streams of liberation motifs. The article employs a feminist epistemology to reconstruct dominant theological motifs and assumptions based on an ethic of care, compassion, and mutuality in relationships.     

Measuring Multicultural Training Reactance: Initial Instrument Psychometrics

Resistant behaviors in multicultural courses are a common dilemma within counselor education. On the basis of psychological reactance theory (J. W. Brehm, 1966), the authors created a multicultural training reactance scale to measure the construct. Exploratory factor analysis and initial reliability and validity data are presented, followed by suggestions that address course reactions. Los comportamientos resistentes en los cursos multiculturales son un dilema frecuente en la educación de consejeros. Basándose en la teoría de reactancia psicológica (J. W. Brehm, 1966), los autores crearon una escala de reactancia en la capacitación multicultural para medir el constructo. Se presenta un análisis factorial exploratorio, así como datos iniciales de fiabilidad y validez, seguidos por sugerencias que abordan las reacciones al curso.     

抗感染治疗新靶点——细菌生物膜

自然条件下,微生物以浮游和生物膜两种生长状态存在,不同生长状态细菌的生物学特征存在显著差异。研究认为细菌生物膜是细菌耐药性形成的重要机制之一,是许多慢性感染性疾病反复发作和难以控制的主要原因。细菌生物膜主要经定植、释放和影响宿主免疫系统而致病,临床常见生物膜相关感染包括生物医学材料相关感染和慢性感染。细菌生物膜及其相关感染,日益成为临床医疗工作的重点和难点。以细菌生物膜为对象,从细菌生物膜及其细菌的生物学特征出发,寻找其特异性药物作用靶点,进行定向药物研发,是解决细菌耐药性和细菌生物膜相关感染的有力措施。
