Substantial progress in handling scientific misconduct cases has been made since the first cases were investigated by the NIH Office of Scientific Integrity in 1989. The successor Office of Research Integrity (ORI) has simultaneously reduced the backlog of cases and increased the professionalism with which they are handled. However, a spate of lawsuits against universities, particularly those brought under the federal False Claims Act, threatens to undermine the ORI by encouraging use of the courts as an alternate route for resolving claims of research misconduct. Next steps should include establishing a government-wide definition of scientific misconduct, providing immunity from lawsuits for institutions that follow proper procedures in investigating charges of scientific misconduct, and participating in the development of international guidelines for maintaining scientific integrity. An earlier version of this paper was presented at the symposium entitled “Misconduct in Science: A Decade of Progress or Merely Years of Controversy” held during the Annual Meeting of the American Association for the Advancement of Science, Philadelphia, Pennsylvania, 13 February, 1998.  相似文献

The effect of a municipal enforcement program to improve residents' packaging of refuse was analyzed in a multiple-baseline design across two areas of a city. The enforcement program involved instruction concerning refuse-packaging regulations, collection only of appropriately packaged refuse, and feedback notices to residents concerning the reasons for noncollection of their inadequately packaged refuse. Both the number of violations and the percentage of residences violating each day were markedly reduced during the enforcement program. Furthermore, sanitation workers considered that the packaging of refuse and the safety and efficiency of refuse collection had improved. This study served as a pilot evaluation of a policy change in the city sanitation department, and was functional in determining the direction of that policy.  相似文献

Observations of children in automobiles were made in seven states before and after implementation of legislation requiring use of child passenger safety devices. Increases in safe seating for children covered by state laws and children under 1 year old were observed in three of the five states implementing legislation during this study. Decreases in safe seating for these age groups were observed in two states, however. Increases in safe seating for children from 1 to 5 years old were observed in four of these five states. Although methodological limitations require cautious interpretation, these data suggest the impact child safety seat laws may have on compliance. Implications of this research for policies on child passenger safety and the importance of exploiting naturally occurring public experiments are discussed.  相似文献

One of the characteristics of autistic children is severe social avoidance behavior. We assessed whether the type of activity (child-preferred vs. activities that were arbitrarily determined by an adult) engaged in during an interaction was correlated with the amount of social avoidance behaviors these children exhibit. Results revealed a negative correlation between appropriate child-preferred activities and social avoidance behavior. Additional analyses revealed that (a) social avoidance behaviors could be manipulated within a reversal design, and would predictably decrease when the children were prompted to initiate appropriate child-preferred activities; and (b) these procedures could be used to teach children to initiate child-preferred activities in community settings, resulting in reductions in social avoidance responses even after the therapist's prompts were completely removed. These data suggest that the manipulation of task variables may influence the severe social unresponsiveness that is characteristic of autistic children.  相似文献

We conducted a large-scale field replication study of classwide peer tutoring applied to spelling instruction (Greenwood, Delquadri, & Hall, 1984). Two hundred and eleven inner-city students in four schools participated during their first- and second-grade school years. The effects of classwide peer tutoring were compared to teacher instructional procedures and pretest probes using a group replication design (Barlow, Hayes, & Nelson, 1984). Analysis of group and individual results indicated that (a) both teacher instructional procedures and classwide peer tutoring were effective in increasing spelling performance above pretest levels, (b) peer tutoring produced statistically greater gains relative to the teachers' procedures for both low and high student groups formed on pretest levels, (c) these outcomes were representative of groups, classes, individuals, and years during the project, and (d) participant satisfaction with the program was generally high. A separate analysis of the social importance of treatment outcome revealed differential findings for low and high groups related to pretest levels. Implications of these findings are discussed.  相似文献

Without internal validity, experimental data are uninterpretable. With intensive designs, most methods presented to quantify a design's internal validity have been subject to criticism. A probabilistic model of intensive designs is presented that demonstrates the high degree of internal validity of these designs without relying on adaptations from traditional inferential statistics. Where the experimenter is able to conform to the restrictions of the model, the equations provide an estimation of internal validity for either reversal or multiple-baseline designs. More importantly, the model provides mathematical bases for some of the common recommendations and design considerations in intensive research (such as the desirability of within-subject replications and of four or more multiple baselines).  相似文献

知识隐藏指组织中个体面对同事知识请求时故意隐瞒或刻意掩饰的行为, 具体包括拖延隐藏、装傻和合理隐藏。知识隐藏不利于个体间知识分享行为的产生, 是知识领域的反生产行为, 对组织效能具有严重破坏作用。针对这一问题, 基于调节定向理论, 从动态视角出发拟通过探究地位动机的维度结构并开发测量工具来探究个体和团队层次中知识隐藏的心理机制及边界条件, 以有助于深化对知识隐藏的规律性认识, 有利于组织更好地应对知识隐藏现象。  相似文献

It is important to understand how people with exhaustion disorder (ED) perceive interventions aiming to facilitate cognitive functioning. Therefore, the overall aim of this study was to explore experiences from persons with ED after participating in a 12-week intervention of either computerized cognitive training or aerobic training. Both interventions were performed in addition to a multimodal rehabilitation programme. Thirteen participants, 11 women and 2 men, were interviewed about pros and cons with participating in the training. The interviews were analysed with Qualitative Content Analysis. The analyses resulted in the theme hopeful struggling for health and the categories support, motivation and sensations. It was hard work recovering from ED. Support from others who are in the same situation, family members, and technology and routines for the training were strongly emphasized as beneficial for recovery. Timing, i.e., matching activities to the rehabilitation programme, getting feedback and perceiving joy in the training were important for motivation. Participants in both interventions experienced positive sensations with improved memory performance, everyday life functioning and increased faith in the prospect of recovery. However, it is important to consider various aspects of support and motivation in both computerized cognitive training and aerobic training to enable participants to pursue their participation.  相似文献
