Working in the weakening of constructive Zermelo-Fraenkel set theory in which the subset collection scheme is omitted, we
show that the binary re.nement principle implies all the instances of the exponentiation axiom in which the basis is a discrete
set. In particular binary re.nement implies that the class of detachable subsets of a set form a set. Binary re.nement was
originally extracted from the fullness axiom, an equivalent of subset collection, as a principle that was su.cient to prove
that the Dedekind reals form a set. Here we show that the Cauchy reals also form a set. More generally, binary refinement
ensures that one remains in the realm of sets when one starts from discrete sets and one applies the operations of exponentiation
and binary product a finite number of times.

We proposed a matching task consisting of pairing an emotional sound and a human face and, after that a noise with an animal. Down syndrome children do not differ with other children in emotional recognition abilities of human faces pictures. Results are compared with those of children with mental retardation and typical children matched on developmental age (K ABC, non-verbal scale). Results do not validate Kasari's presumption concerning with emotional recognition deficit in Down children of 4 years of developmental age mental. 相似文献

Marriage and family therapists practice in more than a third of the rural counties in the United States. However, little is
known about the practice patterns of marriage and family therapists who practice in rural settings. This pilot study examined
the clinical practice and community involvement of a sample of licensed marriage and family therapists in rural Texas. The
results contribute to a small but developing body of research about a relatively unknown group of practitioners. 相似文献

抽象材料选择任务的表象表征视角 总被引:1,自引:0,他引:1
为了探讨在选择任务中表象表征存在的可能性以及抽象材料选择任务困难的原因,该研究设定了材料的内容、规则以及证明规则的要求均完全相同,只是在呈现方式上形象性不同的两种抽象选择任务;然后把两种不同的选择任务分别对数量大致相当的大学生进行了测试。结果发现,不采用类似卡片这种形象性很强的材料呈现方式显著的提高了人们在抽象选择任务中的正确率。实验结果支持了选择任务中表象表征的存在及其为选择任务困难原因之一的观点。 相似文献

Achieving Sustainable Gains in Happiness: Change Your Actions, not Your Circumstances* 总被引:1,自引:0,他引:1
Although attaining happiness is a nearly universal goal, surprisingly little research has focused on how happiness can be
increased and then sustained. Three studies test predictions of a model (Lyubomirsky et al., 2005) positing that sustainable
happiness is possible through intentional activity changes, more so than through circumstantial changes. Study 1 shows that
less hedonic adaptation is reported in response to activity changes than to circumstantial changes. Study 2 tests a dynamic
process model, showing that while both positive activity changes and positive circumstantial changes predict rank-order increases
in subjective well-being from Time 1 to Time 2, only activity changes predict maintained gains at Time 3. Study 3 replicates
the Study 2 findings and extends them to psychological well-being (Ryff and Keyes, 1995). Implications for positive psychology
and “the pursuit of happiness” are discussed.

How Do People Pursue Happiness?: Relating Personality, Happiness-Increasing Strategies, and Well-Being 总被引:1,自引:0,他引:1
Five hundred ethnically diverse undergraduates reported their happiness strategies – that is, activities undertaken to maintain
or increase happiness. Factor analysis extracted eight general strategies: Affiliation, Partying, Mental Control, Goal Pursuit,
Passive Leisure, Active Leisure, Religion, and Direct Attempts at happiness. According to multiple regression analyses, these
strategies accounted for 52% of the variance in self-reported happiness and 16% over and above the variance accounted for
by the Big Five personality traits. The strongest unique predictors of current happiness were Mental Control (inversely related),
Direct Attempts, Affiliation, Religion, Partying, and Active Leisure. Gender differences suggest that men prefer to engage
in Active Leisure and Mental Control, whereas women favor Affiliation, Goal Pursuit, Passive Leisure, and Religion. Relative
to Asian and Chicano(a) students, White students preferred using high arousal strategies. Finally, mediation analyses revealed
that many associations between individuals’ personality and happiness levels are to some extent mediated by the strategies
they use to increase their happiness – particularly, by Affiliation, Mental Control, and Direct Attempts.

Sandra Moore 《Counselling and Psychotherapy Research》2006,6(4):221-226
Although much counselling already takes place in the voluntary sector, little is known about the nature of the work being done or about its effectiveness or the training and experience of its practitioners. Given the gap between the demand for and supply of psychological therapies in Britain today, lack of research into the effectiveness of this work could mean that a valuable resource is being under‐utilised. This paper describes a study of a large, generic counselling centre and, using the CORE monitoring and evaluation system, makes comparisons between its work and that of a number of NHS psychological therapy services. It shows; that it is of at least as complex or severe a nature; and that it is as effective. It also shows that the therapy carried out in this agency is done by appropriately qualified and experienced practitioners. 相似文献

Can we accept John McDowell’s Kantian claim that perception is conceptual “all the way out,” thereby denying the more basic perceptual capacities we seem to share with prelinguistic infants and higher animals? More generally, can philosophers successfully describe the conceptual upper floors of the edifice of knowledge while ignoring the embodied coping going on on the ground floor? I argue that we shouldn’t leave the conceptual component of our lives hanging in midair and suggest how philosophers who want to understand knowledge and action can profit from a phenomenological analysis of the nonconceptual embodied coping skills we share with animals and infants, as well as the nonconceptual immediate intuitive understanding exhibited by experts. 相似文献

Prior research on regret has assumed a consideration set of only two-alternatives. The authors have relaxed that assumption and have developed hypotheses to examine the influence of the unawareness set and order effects in the measurement of consumer regret in a post-purchase evaluation. The results demonstrated that the brands consumers were previously unaware of, do indeed influence consumer regret, especially in a post-purchase upward comparison situation (comparing to superior unknown brands); this was not the case in a post-purchase downward comparison situation (comparing to inferior unknown brands). Order effects were also found to moderate consumer regret. 相似文献

虚拟团队共享心理模型与团队效能的关系 总被引:10,自引:0,他引:10
通过对62个虚拟团队的调研,检验了虚拟团队认同式共享心理模型与分布式共享心理模型构思,并运用多层线性建模技术,对团队特征变量、共享心理模型与虚拟团队效能间的关系进行了分析。结果表明:两类共享心理模型与团队效能间存在显著正相关;团队时间会影响共享心理模型与虚拟团队任务效能间的关系,团队时间会削弱认同式共享心理模型对任务效能间的正向关系,但能加强分布式共享心理模型对任务效能的正面影响;团队规模则主要影响共享心理模型对合作效能的效应,团队规模增加会加强认同式共享心理模型与合作效能间的相关,却会削弱分布式共享心理模型与合作效能间的关系 相似文献
