In an era of increasing medical costs and cries for health care reform in the United States, the pharmaceutical industry has come under intense scrutiny. Ethical issues are inherent in the pharmaceutical marketplace, and there is a need to address the moral rights and responsibilities of drug manufacturers consumers, health care professionals, and governmental agents in the production, distribution, regulation, and use of these products. A dual market system protecting individual rights to access and autonomy without placing an undue strain on societal resources would provide an adequate and equitable framework for an ethical pharmaceutical industry. 相似文献

The purpose of this study was to predict heart rate and blood pressure responses to a stressor task in 166 male and female university students using the multidimensional approach of the Survey of Work Styles. The Survey of Work Styles is comprised of scales for Impatience, Anger, Time Urgency, Work Involvement, Job Dissatisfaction, and Competitiveness. Systolic blood pressure, diastolic blood pressure, and heart rate were measured before and during a 5 min serial subtraction task. Three bipolar Survey of Work Styles profiles were identified for each sex. In males, similarity to each profile was uniquely related to one task cardiovascular measure. In females, two of the three profiles were uniquely related to one physiological measure assessed during the task. The data thus support separate treatment of male and female data. Consideration was given to the possible influence of TABP components, such as Anger, in the differences in the patterns of physiological responses for different Type A profile types. Implications of the physiological results for future studies on psychophysiological differences between Type A and B individuals, and the pathological links between Type A behavior and coronary heart diseases are discussed with emphasis on the recognition of the heterogeneity of personality profiles associated with Type A behavior. 相似文献

In this article, I address piety as a concept shaping Muslim women’s online discussions about gender roles, marriage and professional
careers. I also investigate cross-cultural religious encounters in these women-only groups as I am interested in the potential
of such online environments to facilitate women’s religious reflection and intellectual engagement. Finally, I explore motivations
and religious interpretations of three categories of participants in these discussions: egalitarians, for whom gender equality
is a necessary component of piety (Barlas 2006); traditionalists, identified by other authors as Islamists (Karam 1998) or social conservatives (Gül and Gül 48:1–26, 2000; Mahmood 2005) and finally, holists, a group that cannot be mapped out on the political landscape by using the progressive–conservative
binary (Badran, Agenda 50:41–57, 2001) and which exists and acts outside of it, neither subverting nor enacting norms of any dominant system, be it secular–liberal
or patriarchal. Following Mahmood’s argument that formulating an analysis based exclusively on such a binary is simplistic
(Mahmood 2005), I argue that actions of holists can be only addressed by formulating a set of questions different to those used to analyse
self-defined egalitarians or traditionalists. 相似文献

After half a century of cognitive revolution we remain far from agreement about what cognition is and what cognition does.
It was once thought that these questions could wait until the data were in. Today there is a mountain of data, but no way
of making sense of it. The time for tackling the fundamental issues has arrived. The biogenic approach to cognition is introduced
not as a solution but as a means of approaching the issues. The traditional, and still predominant, methodological stance
in cognitive inquiry is what I call the anthropogenic approach: assume human cognition as the paradigm and work ‘down’ to
a more general explanatory concept. The biogenic approach, on the other hand, starts with the facts of biology as the basis
for theorizing and works ‘up’ to the human case by asking psychological questions as if they were biological questions. Biogenic
explanations of cognition are currently clustered around two main frameworks for understanding biology: self-organizing complex
systems and autopoiesis. The paper describes the frameworks and infers from them ten empirical principles—the biogenic ‘family
traits’—that constitute constraints on biogenic theorizing. Because the anthropogenic approach to cognition is not constrained
empirically to the same degree, I argue that the biogenic approach is superior for approaching a general theory of cognition
as a natural phenomenon.

This study assesses the construct validity of a measure of mental toughness, Loehr's Psychological Performance Inventory. Performers (N = 408, 303 men, 105 women, M age = 24.0 yr., SD = 6.7) drawn from eight sports (artistic rollerskating, basketball, canoeing, golf, rugby league, rugby union, soccer, swimming), and competing at either international, national, county and provincial, or club and regional standards. They completed the 42-item Psychological Performance Inventory during training camps. Principal components analysis provided minimal support for the factor structure. Instead, the exploratory analysis yielded a 4-factor 14-item model (PPI-A). A single factor underlying mental toughness (G(MT)) was identified with higher-order exploratory factor analysis using the Schmid-Leiman procedure. Psychometric analysis of the model, using confirmatory analysis techniques, fitted the data well. Collectively satisfying absolute and incremental fit index benchmarks, the inventory possesses satisfactory psychometric properties, with adequate reliability and convergent and discriminant validity. The results lend preliminary support to the factorial validity and reliability of the model; however, further investigation of its stability is required before recommending practitioners use changes in scores as an index for evaluating effects of training in psychological skills. 相似文献

The mental representation of one's own body does not necessarily correspond to the physical body. For instance, a dissociation between perceived and actual reach-ability has been shown, that is, individuals perceive that they can reach objects that are out of grasp. We presented participants with 3D pictures of objects located at four different distances, namely near-reaching space, actual-reaching space, perceived-reaching space and non-reaching space. Immediately after they were presented with function, manipulation, observation or pointing verbs and were required to judge if the verb was compatible with the object. Participants were faster with function and manipulation verbs than with observation and pointing verbs. Strikingly, with both function and manipulation verbs participants were faster when objects were presented in actual than the perceived reaching space. These findings suggest that our knowledge of the world is implicitly built online through behaviour, and is not necessarily reflected in explicit estimates or conscious representations. 相似文献

Previous studies demonstrated that the sequential verification of different sensory modality properties for concepts (e.g., BLENDER-loud; BANANA-yellow) brings about a processing cost, known as the modality-switch effect. We report an experiment designed to assess the influence of the mode of presentation (i.e., visual, aural) of stimuli on the modality-switch effect in a property verification and lexical decision priming paradigm. Participants were required to perform a property verification or a lexical decision task on a target sentence (e.g., “a BEE buzzes”, “a DIAMOND glistens”) presented either visually or aurally after having been presented with a prime sentence (e.g., “the LIGHT is flickering”, “the SOUND is echoing”) that could either share both, one or none of the target’s mode of presentation and content modality. Results show that the mode of presentation of stimuli affects the conceptual modality-switch effect. Furthermore, the depth of processing required by the task modulates the complex interplay of perceptual and semantic information. We conclude that the MSE is a task-related, multilevel effect which can occur on two different levels of information processing (i.e., perceptual and semantic). 相似文献
