This study explored the perspectives of obstetricians and registered nurses/midwives on the presence of expectant fathers in the delivery room with a view to understanding the implications for the mother as well as the expectant father. A qualitative research design using a phenomenological approach to understand the nuances and challenges that affect the perceptions and attitudes of obstetricians and registered nurses/midwives on the research issue. Five focus group discussions and five key informant interviews were the data collection strategies. Data were coded openly then combined to form themes which were utilized as the framework for data analysis. Three major themes emerged in the findings which included potential benefits to the mother, potential benefits to the father and potential benefits to the relationship. Generally, obstetricians and registered nurses/midwives held positive views about their presence in the delivery suite. This was related to the perceived positive impact that he could have on the woman during the inter-natal and post-natal periods as well as the quality of the relationship. By extension, their presence could have positive long term benefits on the quality of the relationship. The presence of expectant fathers in the delivery room could have a positive impact on the delivery experience for mothers, fathers and the long term relationship. The findings could provide a framework for other studies including a prospective study on the long term implications for the presence of expectant fathers in the delivery room. 相似文献

In Jamaica the public discourse on homosexuality is voluminous, however little or no empirical research or suitably detached
policy-oriented discussion is in evidence. This multidisciplinary qualitative paper uses the content analysis of publicly
available information to explore the posture of key public-policy actors on homosexuals and homosexuality. The observable
implications of the findings for society and the rights of homosexuals are articulated. The paper concludes that this discourse
evinces a settled heteronormative value system, reflecting a consensus on either side of the political divide and applauded
by popular culture and popular opinion. At a time when most of the western world is embracing sexual diversity, these conclusions
carry profound implications for legal reform, employment relations, social justice and public policy in Jamaica. 相似文献

The conflicting views on Tourette's syndrome (TS) and its management in children put forward in the November 1985 issue of Journal of Family Therapy (Nunn, 1985; Prata & Masson, 1985) and the Editorial in the same issue prompt us to report a case. A twelve-year-old boy with TS managed on interactional lines snowed changes more modest than those achieved by Prata and Masson, and we address some of the issues raised by Nunn in his critique of their paper. 相似文献

The purpose of this study was to assess effects of an audience on learning a novel motor skill. Subjects (N=64) were randomly assigned to one of four experimental conditions and administered 15 30-sec. trials with 30 sec. intertrial periods on a pursuit rotor task on two different days. Comparison of Time-on Target performance between conditions indicated that the No Audience condition had significantly higher performance than the Audience condition in Session 1. Comparison of Absolute Retention and Final Retention scores among the four experimental conditions in Session 2 after 48 hr. yielded no significant differences attributable to the presence of an audience, thus supporting the hypothesis that an audience would have no effect on learning. 相似文献

Knowledge-based programs (KBPs) are a powerful notion for expressing action policies in which branching conditions refer to
implicit knowledge and call for a deliberation task at execution time. However, branching conditions in KBPs cannot refer
to possibly erroneous beliefs or to graded belief, such as
“if my belief that φ holds is high then do some action α else perform some sensing action β”.
The purpose of this paper is to build a framework where such programs can be expressed. In this paper we focus on the execution
of such a program (a companion paper investigates issues relevant to the off-line evaluation and construction of such programs).
We define a simple graded version of doxastic logic KD45 as the basis for the definition of belief-based programs. Then we
study the way the agent’s belief state is maintained when executing such programs, which calls for revising belief states
by observations (possibly unreliable or imprecise) and progressing belief states by physical actions (which may have normal
as well as exceptional effects).

Researchers commonly use 2 models to explain contrast effects (CEs): the standard-of-comparison model and the set-reset model. The 2 models focus on the role of categorization to predict when a CE (instead of an assimilation effect) will happen, while minimizing the role of knowledge accessibility and relevance in determining whether any effect will occur. A 3rd model, the selective-accessibility model (F. Strack & T. Mussweiler, 1997), focuses on knowledge accessibility and relevance, but it is a model of assimilation effects in the anchoring bias. In the present study of CEs, the authors tested 3 predictions implied by the selective-accessibility model. The authors found a CE only when anchor- and target-rating dimensions matched and only in the 1st of multiple targets rated. The CE required a minimum amount of attention to the anchor. These results support the account that selective knowledge accessibility and relevance play an important role in CEs. 相似文献

Measures of icon designs rely heavily on surveys of the perceptions of population samples. Thus, measuring the extent to which
changes in the structure of an icon will alter its perceived complexity can be costly and slow. An automated system capable
of producing reliable estimates of perceived complexity could reduce development costs and time. Measures of icon complexity
developed by Garcia, Badre, and Stasko (1994) and McDougall, Curry, and de Bruijn (1999) were correlated with six icon properties
measured using Matlab (MathWorks, 2001) software, which uses image-processing techniques to measure icon properties. The six
icon properties measured were icon foreground, the number of objects in an icon, the number of holes in those objects, and
two calculations of icon edges and homogeneity in icon structure. The strongest correlates with human judgments of perceived
icon complexity (McDougall et al., 1999) were structural variability (r
s = .65) and edge information (r
s = .64). 相似文献

The purpose of the present study was to investigate the extent to which performance of a complex cognitive task of a type resembling that encountered in everyday life is maintained through adulthood. A total of 80 subjects participated; 20 in their thirties, 20 in their fifties, 20 in their sixties, and 20 in their seventies. Subjects were asked to make preference judgments with respect to 32 pocket-size notebooks of a sort they might encounter as consumers in a stationery or variety store. Independently, they were also asked to express their preferences with respect to each of the four dimensions on which the notebooks varied. With only minor differences across age groups, most subjects demonstrated the ability to integrate their individual dimension preferences into a complex preference judgment of an object embodying those dimensions, in a logically consistent manner. 相似文献
