Medicine as business and profession

This paper analyzes one dimension of the frequently alleged contradiction between treating medicine as a business and as a profession, namely the incompatibility between viewing the physician patient relationship in economic and moral terms. The paper explores the utilitarian foundations of economics and the deontological foundations of professional medical ethics as one source for the business/medicine conflict that influences beliefs about the proper understanding of the therapeutic relationship. It, then, focuses on the contrast and distinction between medicine as business and profession by critically analyzing the classic economic view of the moral status of medicine articulated by Kenneth Arrow. The paper concludes with a discussion of some advantages associated with regarding medicine as a business.     

Ambiguity in Our Technical Society

The spiritual situation at the turn of the millennium can be interpreted through Paul Tillich's appropriation of modernity, by analysis of the determinative structures and decisive trends of our age. The methods and organization of industry determine modern society. Spiritually, this situation results in the proliferation of means without ends, the objectification of natural structures, and the reduction of persons to things. Extrapolating from Tillich's analysis, the spiritual situation at the turn of the millennium can be understood as a quasi-religious struggle between the movements of liberal individualism and multiculturalism, both of which lose the sense of ambiguity. The communitarian movement and related interpretations remain the minority voice offering a mediating position.     

Effects of midbrain central gray lesions on spontaneous and electrically induced aggression in the rat

Large electrolytic lesions were placed in the midbrain central gray of male rats. Their effects on hypothalamically induced aggression, switch-off behaviour, and locomotion were investigated. A number of these animals were also tested for territorial intermale aggression in order to compare electrically induced and spontaneous aggression. Large lesions resulted in an increase of the current threshold to induce aggression by hypo-thalamic stimulation. Smaller, but still quite large, lesions decreased the threshold current for hypothalamic aggression. After the operation a decrease in the threshold for switch-off was present, both in the experimental and the control group. Current thresholds for locomotion were decreased after the lesions only in the experimental group. Spontaneous aggression was temporarily decreased after the lesion. No indication was found that other behavioural elements of the animal were distorted by the lesion. The parallel between the effects on spontaneous and electrically induced aggression makes it attractive to ascribe a role to the neural circuit of hypothalamus and central gray in territorial aggression. However, even with large lesions the animals were still capable of fighting, hence the central gray is not indispensable. An attempt was made to explain the differential effects that differently sized central gray lesions have on hypothalamic aggression.     

Testosterone and cortisol responses to competitive fighting in human males: A pilot study

Serum testosterone and cortisol levels were measured by radioimmunoassay in 14 young male judo competitors, in samples taken 10 minutes before and 45 minutes after two different procedures. The first involved physical exercise and the second competitive fighting. Both procedures were of 5 minutes duration and sessions took place at the same time (between 10:00 A.M. and 12:00 P.M. local time) but on different days. Comparing the two situations over all subjects revealed that testosterone increased after exercise and decreased slightly after Competition. Between subject comparisons suggested that contrary to previous claims, winning or losing did not significantly change the testosterone and cortisol levels. Comparisons of subjects who were members of the Regional Team with individuals who were not part of that group confirmed that members increased their testosterone levels after competition, whereas the nonmembers showed a significant decrease. Moreover, success of the individuals, in their sporting record, correlated positively and significantly with the changes of testosterone observed during the competition. These preliminary results suggest that previous personal experience of success can influence the pattern of the psychoendocrine response to a contest situation.     

The assessment of individual “Aggressiveness” in pigeons by a variety of means

Pigeons attack or threaten animate and inanimate targets. The assessment of their aggressiveness was studied by exposing them in their home cages to three different stimuli: the experimenter's hand, a live pigeon, and a rear-projected conspecific image when the birds were exposed to intermittent access to food. A positive correlation between the hand test and live pigeon test was evident, but no relationship between either of these responses and the response to a pictorial image was observed. These results combined with other ethological observations cast doubts on the usefulness of schedule-induced responses to pictorial targets in the assessment of the individual aggressiveness in pigeons, but suggest that the hand test is an adequate and reliable procedure for such evaluations.     

Rivals without a cause? Relative performance feedback creates destructive competition despite aligned incentives

Whether people compete or cooperate with each other has consequences for their own performance and that of organizations. To explain why people compete or cooperate, previous research has focused on two main factors: situational outcome structures and personality types. Here, we propose that—above and beyond these two factors—situational cues, such as the format in which people receive feedback, strongly affect whether they act competitively, cooperatively, or individualistically. Results of a laboratory experiment support our theorizing: After receiving ranking feedback, both students and experienced managers treated group situations with cooperative outcome structures as competitive and were in consequence willing to forgo guaranteed financial gains to pursue a—financially irrelevant—better rank. Conversely, in dilemma situations, feedback based on the joint group outcome led to more cooperation than ranking feedback. Our study contributes to research on competition, cooperation, interdependence theory, forced ranking, and the design of information environments.     

Do representations of male muscularity differ in men's and women's magazines?

Men overestimate the degree of muscularity that is attractive to women, and women overestimate the degree of thinness that is most attractive to men. Consistent with the thesis that sociocultural input influences such body type preferences and beliefs, we postulated that magazines aimed at a male audience would portray a more muscular male body ideal than would magazines aimed at a female audience. Systematic comparison of popular magazines (Cosmopolitan, Men's Health, Men's Fitness, and Muscle & Fitness) revealed that the ideal male body marketed to men is more muscular than the ideal male body marketed to women. We introduce the Physical Trait Overvaluation Hypothesis, which proposes that gender-specific media fuel emphasis on certain body parts in within-gender prestige competitions. The resulting competitive escalation creates a disconnect between the preferences of one gender and the personal aspirations of the other.     

当代大学生对竞争认识的调查研究

以天津市和广州市532名大学生为被试,采用半开放式问卷,采用团体测试的方式,研究了他们对竞争的认识,并对这种认识进行了理论分析。研究结果发现：（1）大学生由竞争一词最易联想到“激烈”、“残酷”、“公平或不公平”、“压力或动力”等内容;（2）大学生认为竞争存在的领域从高到低依次是商业与市场经济、就业与工作、比赛与体育运动、学习与考试、国家与社会等;（3）大学生认为竞争是“激烈”、“残酷”、“对抗”等;（4）大学生认为竞争的主要作用是动力、压力和机遇或挑战;（5）大学生对竞争性质的认识存在显著的性别差异和地区差异。     

The 36th Sir Frederick Bartlett Lecture: An associative analysis of spatial learning

The ability of animals to find important goals in their environment has been said to require a form of learning that is qualitatively different from that normally studied in the conditioning laboratory. Such spatial learning has been said to depend upon the construction of a global representation of the environment, and the acquisition of knowledge about the position of goals with reference to this representation is said to be unaffected by the presence of other cues or landmarks. To evaluate the first of these claims, experiments are described that investigated the extent to which the effects of training in one environment transfer to another. To evaluate the second claim, experiments are described that investigated whether cue competition effects normally found in conditioning studies can be found in spatial tasks. Overall, the results indicate that most of the phenomena of spatial learning can be explained by the principles of associative learning. The implications of the reported results for an understanding of the neural mechanisms of spatial learning are considered.
