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

Learning about hereditary cancer may influence an individual’s self-concept, which otherwise represents a complex but stable
cognitive structure. Recently, a 20-statement self-concept scale, with subscales related to stigma-vulnerability and bowel
symptom-related anxiety, was developed for Lynch syndrome. We compared the performance of this scale in 591 mutation carriers
from Denmark, Sweden and Canada. Principal component analysis identified two sets of linked statements—the first related to
feeling different, isolated and labeled, and the second to concern and worry about bowel changes. The scale performed consistently
in the three countries. Minor differences were identified, with guilt about passing on a defective gene and feelings of losing
one’s privacy being more pronounced among Canadians, whereas Danes more often expressed worries about cancer. Validation of
the Lynch syndrome self-concept scale supports its basic structure, identifies dependence between the statements in the subscales
and demonstrates its applicability in different Western populations. 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

A fear survey schedule (FSS-II) was administered to 1814 undergraduates at the University of Illinois. Females reported significantly more fear than males. Factor analyses indicated that FSS-II taps the following major fear areas: Live Organisms, Death and Illness, Social Interaction, and Social Evaluation. Problems associated with the use of FSS-II total scores for subject selection purposes and with the unsupplemented use of verbal report fear measures were discussed. 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

Psychopathic offenders have difficulty processing contextual or secondary cues once they have initiated goal-directed behavior or allocated attention to a primary task. To test the hypothesis that this deficit in response modulation is specific to conditions in which psychopaths' left-hemisphere resources are engaged, we administered a serial recall task to 21 incarcerated psychopaths and 21 control subjects. Subjects were instructed to memorize eight words that were presented one at a time, each in one of the four corners of the visual display. Subjects' primary task was to recall the words in serial order. Then, without forewarning, they were asked to recall the words' locations. As predicted, psychopaths performed as well as control subjects in recalling words from the left and right spatial fields, but recalled significantly fewer locations from the right spatial field. Thus, psychopaths' deficient response modulation was specific to conditions in which their left-hemisphere resources were actively engaged. 相似文献

Affective and Neutral Tasks (faces with negative or neutral content, with different lighting and orientation) requiring reaction time judgments of poser identity were administered to 32 participants. Speed and accuracy were better for the Affective than Neutral Task, consistent with literature suggesting facilitation of performance by affective content. Priming effects were significant for the Affective but not Neutral Task. An Explicit Post-Test indicated no conscious knowledge of the stimulus frequency that was associated with performance facilitation. Faster performance by female vs. male participants, and differential speeds and susceptibility to priming of different emotions were also found. Anger and shock were responded to most rapidly and accurately in several conditions, showed no gender differences, and showed significant priming for both RT and accuracy. Fear and pain were responded to least accurately, were associated with faster female than male reaction time, and the accuracy data showed a kind of reverse priming. 相似文献

A recent forum in JFD (28/3, 2003) evaluated the status of evidence-based practice in fluency disorders, and offered recommendations for improvement. This article re-evaluates the level of support available for some popular approaches to stuttering therapy and questions the relative value placed on some types of programs endorsed by the forum. Evidence-based practice is discussed within the context of emerging concerns over its application to non-medical interventions and suggestions are made for grounding fluency interventions by reference to empirically supported principles of change. A popular, evidence-based intervention for stuttering in young children (the Lidcombe program) is evaluated within the suggested parameters. EDUCATIONAL OBJECTIVES: After reading this article, the reader will be able to: (1) evaluate the status of evidence-based practice in fluency disorders; (2) list concerns about the impact of narrow interpretation of EBP on research and practice in the field of fluency disorders and other non-medical domains; (3) articulate the role of theory and basic research in selecting among and evaluating therapy approach options. 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).

Past research has suggested that children who stutter (CWS) may have less well-developed language skills than fluent children, and that such relative linguistic deficiencies may play a role in precipitating their disfluencies. However, data to support this position are primarily derived from results of standardized diagnostic inventories, which are originally designed to identify frank language impairment. Nonword repetition has emerged as a more sensitive measure of children's linguistic abilities. In this exploratory study, eight CWS (mean age 5:10, range 4:3-8:4) were compared to eight normally developing children (ND) (mean age 5:9, range 4:1-8:4) in their ability to repeat the nonwords of the Children's Test of Nonword Repetition. CWS performed more poorly than NS on measures of Number of Words Correct and Number of Phoneme Errors at all nonword lengths, although statistical differences were observed only for 3-syllable nonwords. When lexical stress of the nonwords was varied to a non-English stress pattern, all participants repeated the stimuli with less accuracy, and the CWS again exhibited more errors than NS. Fluency for the CWS group did not change systematically with increasing nonword length. These preliminary findings are interpreted in light of a number of extant theories of the underlying deficit in childhood stuttering. We conclude that children who stutter may have diminished ability to remember and/or reproduce novel phonological sequences, and that further investigation into this possibility may shed light on the emergence and characteristics of childhood stuttering. EDUCATIONAL OBJECTIVES: After completing this activity, the learner will: (1) be able to evaluate the research support for a linguistic component to stuttering; (2) describe the use of nonword repetition as an experimental and assessment device with children with SLI and children who stutter; (3) suggest future directions for research to further refine the potential role that linguistic encoding plays in the etiology and persistence of stuttering. 相似文献
