Circadian factors during sustained performance: Background and methodology

Cornell University Medical College, Westchester Division, The New York Hospital, White Plains, New York It is well established that there is a complex timekeeping mechanism in the human brain. This mechanism is associated with a variety of physiological and psychological rhythms having a period of about a day, and thus referred to as circadian rhythms. The circadian system has recently been modeled in terms of two underlying oscillators, one much more resistant to changes in routine than the other. These oscillators are considered to be endogenous, that is, internal to the organism, and not reliant for their existence upon changes in the person’s environment or general behavior. They thus continue to run even when the sleep/wake cycle is suspended, as in sustained operations. Thus, by their very nature, sustained operations require the individual to override the inputs that are coming from his or her circadian system (especially the indication that sleep is required). The aim of this paper is to provide a background to the area of circadian rhythms research, including a section on the methodology, so that the impact of the circadian system on sustained operations can be better understood.     

“亚当·斯密问题”的逻辑张力

“亚当·斯密问题”是指斯密的《国富论》与《道德情操论》之间存在着对立或不一致的问题,最初由十九世纪中叶的德国历史学派所提出。此后,随着现实与理论的发展,出现了不同的看法。学者们普遍认为,斯密的两大著作之间、经济学与伦理学之间存在着对立或者不存在对立,而是相互一致的。这些看法都具有各自的积极合理的内容,但缺乏辩证的观点,而没有看到“斯密问题”自身的逻辑张力,也就是说,“斯密问题”所指涉的是现实的经济与伦理之间及作为其理论表现的经济学与伦理学之间的关系。“斯密问题”所含的这些关系呈现出了一个动态的、由肯定到否定再到否定之否定的辩证过程。     

Developing Dyadic Evaluation for Supervision: An Exploratory Factor Analysis

This study addresses the need for empirically validated tools to support the training, supervision, and the discovery of best practices in Marital and Family Therapy (MFT). This project represents a first step in developing the Dyadic Supervision Evaluation (DSE), an assessment tool that is grounded in developmental and systemic theory and is psychometrically strong. An Exploratory Factor Analysis (EFA) approach was applied to data from 88 trainee-supervisor dyads across four time periods during the first year of clinical training, resulting in 20 factors, including 9 factors for trainees and 11 factors for supervisors with internal reliabilities ranging from α’s = .82–.98. Discussion addresses the utility of the DSE in documenting the developmental and dyadic progression of supervision during the first year of MFT training.     

Ethical and legal issues in group counseling

Legal and ethical issues involved in group work are reviewed and discussed. Variations in different professional ethics codes are discussed. Recommendations for consideration by group leaders are made.     

Presence and television.

Film and a number of emerging entertainment technologies offer media consumers an illusion of nonmediation known as presence. To investigate the possibility that television can evoke presence, 65 undergraduate students were shown brief examples of rapid point‐of‐view movement from commercially available videotapes on a television with either a small screen (12 inches [30.5 cm], measured diagonally) or a large screen (46 inches [116.8 cm]). Participants' responses were measured via a questionnaire and a computer‐based recording of arousal (electrodermal activity). Viewers of both televisions reported an enjoyable sense of physical movement, excitement, involvement, and a sense of participation. Furthermore, as predicted, participants who watched the large screen television thought the movement in the scenes was faster, experienced a greater sense of physical movement, enjoyed the movement to a greater extent, found the viewing experience more exciting, and were more physiologically aroused. Practical and theoretical implications are discussed.     

Age,Emotion Regulation Strategies,Temperament, Creative Drama,and Preschoolers' Creativity

Based on Yeh's (2004) Ecological Systems Model of Creativity Development, this study investigated the effects that age, the use of emotion regulation strategies, temperament, and exposure to creative drama instruction have on the development of creativity among preschool children. Participants were 1164‐ to 6‐year‐old preschool children. This study categorized the emotion regulation strategies used by preschool children and developed a creativity test which includes the measurement of usefulness, an indicator of creativity that has, until now, been ignored. The main findings are that (a) 6‐year‐olds outperform 4‐ and 5‐year‐olds in terms of creativity; (b) emotion regulation strategies as well as a positive temperament have positive effects on children's creativity; (c) creative drama instruction contributes to children's creativity; and (d) age group, emotion regulation strategies, temperament, and creative drama instruction can collectively predict children's creativity.     

Exploring the Relationship Balance Assessment

Assessments of power in couples’ relationships often only survey one partner, but they do not take into consideration both partners’ perceptions. Thus, many assumptions about power and equality in relationships have not been quantitatively tested due to a lack of dyadic measures of power. Therefore, the purpose of the Gender and Relationships Study was to develop and test a new scale of equality and relative power for couples, the Relationship Balance Assessment (RBA). The RBA may be useful for research and for clinical work with couples to help raise awareness of the balance of power in their relationship. A review of the literature has shown a shift away from focusing on monetary resources and decision-making dominance towards examining relationship processes and the connection between gender and power. This study prescreened a pool of process-oriented questions based on the qualitative literature. Then exploratory factor analysis of data from 268 individuals and 91 couples identified 12 consistent latent factors underlying relationship equality. These 12 subscales are summed up with the TREASURES acronym: Time Discretion, Relational Power, Emotional Power (Emotional Expression and Avoidance subscales), Accommodation, Spending and Saving subscales, Union or Sexual Dominance, Rational Power, Economic Role Power (Status and Childcare subscales), and Social Choices.     

Temporary,inconsistent, and null effects of a moral story and instruction on honesty

Lying during childhood is a common concern for caregivers. Lee et al. (2014) showed that a moral story and instruction implying reinforcers for honesty produced statistically significant improvements in children admitting a transgression. We evaluated the influence of this moral story and instruction on the consistency of honest reports when reinforcement favored lying in the context of reporting answers to math problems. The moral story and instruction produced temporary, inconsistent, or null effects across participants. However, reinforcing accurate reports produced consistent improvements in telling the truth.
