A loss of faith: the sources of reduced political legitimacy for the American medical profession.
(41/1365)
The political legitimacy and policymaking influence of the medical profession have greatly declined in American society over the past 30 years. Despite speculation about the causes, there has been little empirical research assessing the different explanations. To address this gap, data collected in 1995 are used to compare attitudes of the American public and policy elites toward medical authority. Statistical analyses reveal that (1) elites are more hostile to professional authority than is the public; (2) the sources of declining legitimacy are different for the public than they are for policy elites; and (3) the perceptions that most threaten the legitimacy of the medical profession pertain to doubts about professional competence, physicians' perceived lack of altruism, and limited confidence in the profession's political influence. This article concludes with some speculations about the future of professional authority in American medicine. (+info)
The tyranny of diagnosis: specific entities and individual experience.
(42/1365)
The articulation and acceptance of specific disease entities constitute one of the most important intellectual and cultural events of the past two centuries. This notion is central to how we organize health care delivery, think about ourselves, debate and formulate social policy, and define and manage deviance. Diagnosis is indispensable to linking specific disease concepts with doctor and patient and the social and economic institutions shaping such clinical interactions. Disease is a social entity, not an array of ideal types. The history of medicine is partly the story of how disease entities have become social entities, accumulating the flesh of diagnostic and therapeutic practice, social expectation, and bureaucratic reification. Despite criticism of reductionist medicine in the West and less focus on disease entities and mechanisms, our social response still depends on this concept of sickness. But this concept can no longer remain invisible if we are to understand contemporary medicine as both a social and a technological system. (+info)
Successive intervals analysis of preference measures in a health status index.
(43/1365)
The method of successive intervals, a procedure for obtaining equal intervals from category data, is applied to social preference data for a health status index. Several innovations are employed, including an approximate analysis of variance test for determining whether the intervals are of equal width, a regression model for estimating the width of the end intervals in finite scales, and a transformation to equalize interval widths and estimate item locations on the new scale. A computer program has been developed to process large data sets with a larger number of categories than previous programs. (+info)
Estimating the efficiency of recognizing gender and affect from biological motion.
(44/1365)
It is often claimed that point-light displays provide sufficient information to easily recognize properties of the actor and action being performed. We examined this claim by obtaining estimates of human efficiency in the categorization of movement. We began by recording a database of three-dimensional human arm movements from 13 males and 13 females that contained multiple repetitions of knocking, waving and lifting movements done both in an angry and a neutral style. Point-light displays of each individual for all of the six different combinations were presented to participants who were asked to judge the gender of the model in Experiment 1 and the affect in Experiment 2. To obtain estimates of efficiency, results of human performance were compared to the output of automatic pattern classifiers based on artificial neural networks designed and trained to perform the same classification task on the same movements. Efficiency was expressed as the squared ratio of human sensitivity (d') to neural network sensitivity (d'). Average results for gender recognition showed a proportion correct of 0.51 and an efficiency of 0.27%. Results for affect recognition showed a proportion correct of 0.71 and an efficiency of 32.5%. These results are discussed in the context of how different cues inform the recognition of movement style. (+info)
Dealing with the dangers of fear: the role of risk communication.
(45/1365)
Among the many lessons of the homeland terrorist attacks of 2001 was that fear has powerful public health implications. People chose to drive instead of flying, thereby raising their risk of injury or death. Thousands took broad-spectrum antibiotics to prevent possible anthrax infections, thereby accelerating antimicrobial resistance. Such potentially harmful actions were taken by people seeking a sense of safety because they were afraid. This essay argues for greater emphasis on risk communication to help people keep their fears in perspective. Effective communication, not only through what the government says but implicit in the actions it takes, empowers people to make wiser choices in their own lives, and to support wise choices by society in applying limited resources to maximize public and environmental health.

Are you looking at me? Accuracy in processing line-of-sight in Turner syndrome.
(46/1365)
The behavioural phenotype of women with Turner syndrome (X-monosomy, 45,X) is poorly understood, but includes reports of some social development anomalies. With this in mind, accuracy of direction of gaze detection was investigated in women with Turner syndrome. Two simple experimental tasks were used to test the prediction that the ability to ascertain gaze direction from face photographs showing small lateral angular gaze deviations would be impaired in this syndrome, compared with a control population of men and women. The prediction was confirmed and was found to affect both the detection of egocentric gaze from the eyes ('is the face looking at me?') and the detection of allocentric gaze, where the eyes in a photographed face inspected one of a number of locations of attention ('where is she looking?'). We suggest that dosage-sensitive X-linked genes contribute to the development of gaze-monitoring abilities. (+info)
Acute SSRI administration affects the processing of social cues in healthy volunteers.
(47/1365)
Enhancement of serotonin neurotransmission plays an important role in the antidepressant response to agents presently available to treat depression. This response forms the major evidence for the role of serotonin in affective and social behaviour in humans. The present study investigated the effects of acute administration of the selective serotonin reuptake inhibitor (SSR1), citalopram (10 mg, i.v.) upon a measure of emotional processing in healthy female volunteers. Subjects completed a facial expression recognition task following infusion of citalopram or saline (between-subjects design, double-blind). Facial expressions associated with five basic emotions--happiness, sadness, fearfulness, anger and disgust--were displayed. Each face had been 'morphed' between neutral (0%) and each emotional standard (100%) in 10% steps, leading to a range of emotional intensities. Mood and subjective experience were also monitored throughout the testing session. Volunteers receiving citalopram detected a higher number of facial expressions of fear and happiness, with reduced response times, relative to those given the placebo. By contrast, changes in the recognition of other basic emotions were not observed following citalopram. Notable differences in mood were also not apparent in these volunteers. These results suggest that acute administration of antidepressant drugs may affect neural processes involved in the processing of social information. This effect may represent an early acute effect of SSRIs on social and emotional processing that is relevant to their therapeutic actions. (+info)
Information disclosure and smoking risk perceptions. Potential short-term impact on Spanish students of the new European Union directive on tobacco products.
(48/1365)
BACKGROUND: The Directive 1999/0244 (COD), recently approved by the European Parliament, proposed that the content and presentation of health warnings on cigarette packets be modified. The aim of the present study was to analyse the potential effect of the planned measures on the perceptions by Spanish youth of the risks associated with smoking. METHOD: A sample of 435 students attending the University of La Rioja were surveyed on their perceptions of the principal health risks attributable to the consumption of tobacco i.e. lung cancer, respiratory diseases and cardiovascular disease. A questionnaire was administered before and after they were presented with a demonstration of the health warnings on cigarette packets based on the new European Union directive. RESULTS: Perceptions changed significantly following exposure to the content and type of information of the new packaging. In general, the university students attributed a higher health risk to smoking following the presentation. CONCLUSIONS: The measures developed by the public sector to present a higher profile of anti-tobacco health warnings do influence the target population in the desired direction, at least in the short term. Hence, given that the perception of risk influences the election to smoke, it is predictable that when these types of policy decisions are applied, there will be a tendency towards a reduction in the incidence and prevalence of tobacco consumption.
