重症急性胰腺炎预防抗生素治疗的争议

重症急性胰腺炎伴随高病死率,细菌和真菌感染是其导致死亡的主要原因之一。目前治疗一般采取预防性抗生素治疗,但预防性抗生素治疗又可能会加重二重感染。目前研究结果数量有限,结果不一。是否应该应用预防抗生素治疗仍然存在争议,期待更多设计合理的随机对照试验。     

The Influence of Child Gender on the Prospective Relationships between Parenting and Child ADHD

The aims of the current study were to (i) explore the potential bidirectional, prospective relationships between parenting and child ADHD, and (ii) explore whether these relationships differed on the basis of child gender. Data were obtained from waves 1 (children aged 4- to 5-years) to 5 (children aged 12- to 13-years) of the Longitudinal Study of Australian Child (LSAC) dataset (child cohort). In order to examine dimensions of both mothers’ and fathers’ parenting, a subsample of nuclear families with mothers, fathers and children present at all waves was extracted (final sample = 1932; sons = 981, daughters = 951). Child ADHD measures included the hyperactive-impulsive subscale of the strengths and difficulties questionnaire for symptoms, and parent-report question for diagnosis. Mothers and fathers completed scales on dimensions of Angry, Warm and Consistent Parenting. A cross-lagged panel model demonstrated (i) higher child ADHD symptoms at wave 1 led to a global increase in less-than-optimal parenting at wave 2, and (ii) child ADHD symptoms and Angry Parenting shared a prospective, bi-directional relationship (whereby increases in one predicted increases in the other over time) during earlier years of development. Latent growth curve models demonstrated that increases in Angry Parenting across time were significantly predicted by increases in child ADHD symptoms. A logistic regression demonstrated that both mothers’ and fathers’ Angry Parenting at wave 1 significantly predicted an ADHD diagnosis in children at wave 3. No predictive relationships differed between child genders; thus, it appears these prospective pathways are similar for both sons and daughters.     

The Katz-Francis Scale of Attitude toward Judaism: Internal Consistency Reliability and Construct Validity among Female Undergraduate Students in Israel

The Katz-Francis Scale of Attitude toward Judaism was developed to extend to the Jewish community a growing body of international research concerned to map the correlates, antecedents, and consequences of individual differences in attitude toward religion as assessed by the Francis Scale of Attitude toward Christianity. The internal consistency reliability and construct validity of the Katz-Francis Scale of Attitude toward Judaism were supported by data provided by 284 Hebrew-speaking female undergraduate students attending Bar-Ilan University. This instrument is commended for application in further research.     

男性与女性对不同性别和种族面孔识别的差异

研究以大学生为被试,采用延时匹配任务,旨在探讨性别和种族因素对面孔识别的影响,结果发现:(1)男、女被试对女性面孔识别的反应时及正确率均优于男性面孔;(2)被试对不同种族女性面孔识别的优势存在差异,被试对高加索女性面孔的识别表现为更高的正确率,而对中国女性面孔的识别表现为更快的识别速度;(3)面孔种族是导致女性面孔识别优势的重要影响因素。研究表明,面孔识别受到面孔种族、面孔性别和被试性别共同作用的影响。     

Co-creating shared realities with couples

We are presenting a unique approach to understanding couples and relationships based on social constructionist principles. It is our belief that individuals possess constructions of reality with regard to relationships and must co-create a reality in which both partners participate. The implication of this theoretical principle is that differences between partners are not as important as the negotiation of such differences. One thousand premarital couples were examined to determine the effect of levels of flexibility and perceived differences on the quality of their relationships. Data analysis revealed that levels of flexibility were a significant factor in couples' abilities to cocreate a successful shared reality.Portions of this paper were presented at the annual conference of the American Association for Marriage and Family Therapy, October 1992, Miami Beach, FL.Both authors were primary contributors to this paper.     

Using Minuchin's structural family therapy techniques with Italian-American families

Italian-American families have general characteristics about which family therapists should be informed in order to select appropriate and effective family therapy for this cultural group. The author identifies Minuchin's structural family therapy techniques as relevant for working with Italian-American families, adding a note of personal validation of the need and efficacy of the Minuchin approach.     

An Investigation of the Structural Validity of Loevinger's Model and Measure of Ego Development

This study demonstrates the use of structural equation modeling for investigating a hierarchical model of personality based on Loevinger's (1976) conceptualization. This model was constructed to have a multifactorial and hierarchical structure in which the ego development construct served as the source of covariation for specific personality constructs of impulse control, interpersonal style, conscious preoccupations, and cognitive style. This model and three other conceivable models were investigated to determine which structure best represented the relations among specific personality constructs and ego development. The specific personality constructs were identified by measures chosen from the available pool of measures that were compatible with Loevinger's conceptualization. The four conceivable models were fitted to sample data from 267 adult subjects using confirmatory factor analysis and were compared with indices of model fit and methods for comparison of nested models. Results suggested that the four specific personality constructs and ego development are part of the same process. Although a hierarchical structure appeared tenable for this process, the role of ego development perhaps is not as dominant as envisioned by Loevinger. These results must be considered tentative due to measurement limitations.     

Quantitative theories of metacontrast masking

In metacontrast masking, the effect of a visual mask stimulus on the perceptual strength of a target stimulus varies with the stimulus-onset asynchrony (SOA) between them. As SOA increases, the target percept first becomes weaker, bottoms out at an intermediate SOA, and then increases for still larger SOAs. As a result, a plot of target percept strength against SOA produces a U-shaped masking curve. Theories have proposed special mechanisms to account for this curve, but new mathematical analyses indicate that it is a robust characteristic of a large class of neurally plausible systems. The author describes 3 quantitative methods of accounting for the U-shaped masking effect and analyzes 4 previously published mathematical models of masking. The models produce the masking curve through mask blocking, whereby a strong internal representation of the target blocks the mask's effects.
