For scientific knowledge to be trustworthy, it needs to be dissociated from material interests. Disinterested research also
performs other important non-instrumental roles. In particular, academic science has traditionally provided society with reliable,
imaginative public knowledge and independent, self-critical expertise. But this type of science is not compatible with the
practice of instrumental research, which is typically proprietary, prosaic, pragmatic and partisan. With ever-increasing dependence
on commercial or state funding, all modes of knowledge production are merging into a new, ‘post-academic’ research culture
which is dominated by utilitarian goals. Growing concern about conflicts of interest is thus a symptom of deep-seated malaise
in science and medicine.
An expanded version of this paper was presented at an International Conference on “Conflict of Interest and its Significance
in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002. 相似文献

The purpose of this review was to report on the effectiveness and focus of academic self-management interventions for children and adolescents with emotional and behavioral disorders. Twenty-two studies published in 20 articles and involving 78 participants met inclusionary criteria. The overall mean effect size (ES) across those studies was 1.80 (range –0.46 to 3.00), indicating effects were generally large in magnitude and educationally meaningful. Self-monitoring interventions were the predominant type of self-management technique used by researchers. The mean ES for intervention types were self-evaluation (1.13), self-monitoring (1.90), strategy instruction techniques (1.75), self-instruction techniques (2.71), and multiple-component interventions (2.11). Interventions targeted improvement in math calculation skills more than any other area. The mean ES by academic area were math interventions (1.97), writing (1.13), reading (2.28), and social studies (2.66). There was evidence to support a claim of the generalization and maintenance of findings. Implications, limitations, and areas for future research are discussed. 相似文献

This paper reported two studies investigating high school students’ academic self-schemas in learning mathematics and their self-congruent learning engagement patterns. Using cluster analyses, Study 1 located two contrasting groups of students holding positive and negative self-schemas in learning mathematics among Chinese participants. MANOVA analyses showed that these two groups of Chinese schematic students differed from each other in the use of achievement goals, approaches to learning, and expected levels of performance. These findings were validated and extended in Study 2 using a culturally different sample, Australian students. Again, cluster analyses successfully classified Australian participants into positive and negative schematic clusters. It was also found that these two groups of schematic students approached learning mathematics in a self-congruent manner similar to those found in Study 1. The converging results in both studies lent empirical support to the theoretical formulation of positive and negative schematic students and the validity of using the self-schema concept to investigate motivation and learning. The differences in their learning engagement patterns were discussed in terms of students’ different academic self-schemas in learning mathematics. 相似文献

This study extends the data on the efficacy of cognitive interventions for patients with chronic medical problems and describes the case of a 37-year-old woman with an anxiety disorder related to diabetes. The effects on panic frequency, use of safety behaviour and related beliefs were investigated after the introduction of two main cognitive-behavioral interventions. The results are consistent with predictions from the cognitive model of panic. This case demonstrates the usefulness of directly challenging the 'meaning' of the feared situation in order to produce clinically significant improvements in the management of physical disease. 相似文献

Justification for public funding of academic research is based on the linear model of technological advance first proposed by Francis Bacon. The model hypothesizes that government subsidized science generates new technology which creates new wealth. Mainstream economics supports Bacons model by arguing that academic research is a public good. The Bayh–Dole Act allows universities to privatize federally funded research and development (R&D) which is in direct conflict with the public good argument. Diminishing returns to university R&D, challenges to Bacons linear model and the labor exploitation of young scientists by research universities suggest that policy makers may want to reconsider the system for allocating federal R&D to universities and colleges. 相似文献

The effect of presession attention on the later occurrence of problem behavior was examined with elementary-school children with a range of disabilities. Results of analogue functional analyses suggested an escape function, an attention function, or both. Following the analogue functional analyses, the effects of two antecedent conditions (10-min ignore vs. 10-min attention) were compared on problem behavior in subsequent test conditions. For participants who displayed attention-maintained problem behavior, the test condition involved contingent attention for problem behavior. For participants who displayed escape-maintained problem behavior, the test condition involved contingent escape for problem behavior. Results indicated that participants who displayed attention-maintained problem behavior displayed less problem behavior following presession exposure to attention than when ignored. No such effect was found for presession attention on escape-maintained problem behavior. We discuss matching antecedent-based interventions to the results of functional analysis. 相似文献

The purpose of this study, using an online methodology, was to investigate therapists' perceptions of the role of creativity in couples' and family therapy. Along with completing a quantitative measure assessing creativity in their work, participants responded to four open-ended questions which addressed the meaning of creativity, characteristics of a creative family therapist, some creative interventions they have used with couples and families, and barriers to their own creativity as a family therapist. A total of 142 marriage and family therapists in 36 states in the United States participated. The findings shed light on the unique importance of creativity in couples and family treatment. 相似文献

We present an approach to the problem of structuring a therapeutic alliance with patients presenting paranoid symptoms, using both psychoanalytical and cognitive techniques. Initially, we focused on one of the main aspects of the paranoid worldview: the fear of being betrayed and the tendency to betray. This is a defense maneuver, through which patients deny their passivity, and the impotence in the relationship with their own internal needs and with the significant people in the external world, including the therapist. In our experience to build up a working relationship, both a psychoanalytical interpretation of unconscious conflicts and the cognitive analysis of dysfunctional beliefs are needed. Often, in more serious cases, the role of nonqualified object must be accepted at the beginning, due to the patient's need to be in control of the situation. Only then can a therapeutic phase begin, in most cases, through an integrated approach that includes pharmacological, psychodynamic, and cognitive modalities. 相似文献
