National, Ethnic or Civic? Contesting Paradigms of Memory, Identity and Culture in Israel

Zionist national identity in Israel is today challenged by two mutuallyantagonistic alternatives: a liberal, secular, Post-Zionist civic identity, on the one hand, and ethnic, religious, Neo-Zionist nationalistic identity, on the other. The other, Zionist, hegemony contains an unsolvable tension between the national and the democratic facets of the state. The Post-Zionist trend seeks a relief of this tension by bracketing the nationalcharacter of the state, i.e., by separation of state and cultural community/ies; the Neo-Zionist trend seeks a relief of the same tension by bracketing the democratic nature of the state, i.e., by consolidating the Jewish ethno-national character of the state. The focus of the study is upon two dimensions of this unfolding cultural-political strife: the conflicting perceptions of time and space, and the ways they affect the perceptions of the boundaries of the collectivity, either in an inclusionary manner (the ``post') or in an exclusionary manner (the ``neo').     

The Use of the Devereux Scales of Mental Disorders in the Assessment of Attention-Deficit/Hyperactivity Disorder and Conduct Disorder

The present study was designed to gather validity data on the Devereux Scales of Mental Disorders (DSMD) for distinguishing among children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD; N = 32), Conduct Disorder (CD; N = 34), or no clinical diagnosis (NC; N = 65). Three types of indicators were compared: (a) DSMD scale, composite, and total scores, (b) the number of ADHD or CD-related items endorsed, and (c) diagnostic efficiency statistics (e.g., sensitivity, positive and negative predictive power). The clinical groups did not differ significantly from each other, but both were significantly higher than the NC group on all DSMD scales. Moreover, there were significant differences between the ADHD and the CD groups on the number of respective ADHD and CD-related items endorsed. A cut-off of seven to eight items yielded the best discrimination between the two diagnostic groups. Diagnostic efficiency statistics indicate that the DSMD may be effective at differentiating between similar disruptive behavior disorders.     

Interviewing a Therapist in the Presence of a Couple: A Description of the Therapeutic Process

A therapy research team interviewed a therapist in the presence of a couple. Following each of six consecutive sessions with a couple, an interviewer posed questions to the therapist and couple. While one question was standard to each interview, other questions were generated by team members who tracked the entire process via live observation. These questions were directed first at the therapist, then at the couple, and then focused on therapeutic process and outcome. Findings of this process for the therapy system included decreasing the hierarchy within the client/therapist relationship; increasing the client ownership and energy in the therapy process; discovering the presence of parallel processes between the systems; and informing the direction of future therapy sessions. Practical, clinical implications are discussed for a variety of therapy settings.     

增塑剂DEHP的神经和行为发育毒性

增塑剂邻苯二甲酸二乙基己酯(Di-(2-ethylhexyl) phthalate,DEHP)是一种具有拟雌激素和抗雄激素活性的环境内分泌干扰物,人类和野生动物可通过不同途径终生暴露于DEHP.母体摄入的DEHP可通过胎盘和乳汁转入子代体内并进入脑组织.围生期DEHP暴露性别特异性地改变子代大鼠下丘脑视前区芳香酶活性而影响雌激素合成,并通过改变雌激素受体活性干扰雌激素对脑发育的调节作用.DEHP及其代谢产物可以影响神经细胞的增殖分化和突触形成,干扰性激素调控发育过程中的下丘脑氨基酸递质系统对促性腺激素释放激素分泌的刺激作用,影响中脑多巴胺递质系统发育而诱导自发性多动症.DEHP对脑发育的作用最终影响动物的早期行为、学习记忆和情感等行为发育.     

Psychological state and psychological strain in relation to infertility

The purpose of the study was to explore the relationship between psychological state and perceived strain in relation to fertility problems. Couples presenting at an infertility clinic completed, on two occasions seven months apart, a series of standardized measures to assess psychopathology. In addition, they completed a weekly diary rating their mood state or distress/strain over a period of 22 weeks, during which investigations and treatment were taking place. Little evidence of psychopathology was found in the sample; the weekly diaries also suggested a general lack of distress/strain, even in response to medical investigations and diagnosis. The results are discussed in the light of wide individual variations in ratings obtained from the diaries. Participants with high distress/strain scores tended to have significantly higher initial scores on the psychometric measures administered. Participants with high distress/strain scores were also more likely to show a further significant increase in distress/strain scores in relation to diagnostic information. It is argued that a task for future research is to determine the characteristics of those couples who are likely to experience difficulty in coping with the strain of infertility investigations so that counselling resources and support services can be most effectively targeted. © 1998 John Wiley & Sons, Ltd.     

Developing coherence in community and clinical psychology: the integration of idealism and pragmatism

Illustrations of how ideas from community psychology may be integrated with clinical psychological thinking and practice are described from the perspective of a clinical psychologist working in the NHS. The intentions are to consider socially relevant conceptualizations of the causes of people's well-being and distress, and to develop ways of helping individuals and communities to clarify and address these causes. Incorporating an analysis of social power also necessitates a critical awareness of the limited potency of psychological interventions. © 1998 John Wiley & Sons, Ltd.     

Child-oriented family therapy in China: A cross-cultural application of integrative family therapy targeting children aged 4–10

This article describes child-oriented family therapy (COF), a family therapy approach to early psychological and behavioral problems that is widely applied in northern Europe and has been adopted by countries with different cultures, such as Germany and China. This article explains the theoretical background, setting, characteristics, development and effective factors of this method and explores relevant research. In addition, the application of this method in China and reflections on its applicability to families in different cultures are presented. A clinical case is provided to illustrate the core therapeutic principles of COF. Since the application of COF interventions to families with children in Asian cultures remains understudied, the widespread availability of COF and adaptation to local conditions could facilitate training and research achievements in this field.
