This study assesses the authorship of legal scholarship within 20 criminology and criminal justice (CCJ) journals from 2005 to 2015, examining trends over time and variation across journals in the prevalence of sole-authorship and the mean number of authors and identifying the most prolific authors of legal scholarship published in CCJ journals. The study thus sheds light on the extent of collaboration among CCJ legal scholars and identifies CCJ legal scholars who have remained largely invisible due to their focus on a marginalized subfield.  相似文献

Consultation is a promising approach to creating change in early childhood programs, from innovations in instructional strategies to the enhancement of global program quality. Studies of consultation effectiveness have been hampered by limited reports of implementation fidelity related to consultation procedures. This article describes the challenges of supporting and measuring implementation fidelity in a 5-state study in which community consultants followed a collaborative consultation model to enhance global quality in childcare programs. The authors consider the limitations of using a randomized experimental design to study the effectiveness of consultation and share lessons learned in their efforts to enhance treatment fidelity without compromising the basic tenets of the model or the rigorous design.  相似文献

The relationship between institutional change and entrepreneurship is poorly understood. We build the theory in this area by tracing institutional change in the US electric power industry over a 40-year period. Our analysis shows that environmental jolts mobilize actors to reformulate institutions, resulting in increased entrepreneurial opportunity. When the institutional environment is stable, we find that incumbent organizational forms and embedded logics present formidable obstacles to entrepreneurial activity. Environmental jolts, however, catalyze search processes and motivate the evaluation of current institutional logics. Specifically, in the case of the electric power industry, environments of abundance and regulation resulted in homogeneity of organizational structures and strategies, and few entrepreneurial opportunities. Environments marked by scarcity and crisis, however, witnessed heavy scrutiny of existing institutional arrangements that eroded their taken-for-grantedness and symbolic value, resulting in opportunities for entrepreneurial action.  相似文献

Conclusions It is quite evident that the auditory aspects of the film used in the study superseded the visual ones. Since both sensory modalities can reinforce each other in many films, those films can be used to educational advantage. Behavioral science films, however—placing most importance not on the habit of looking, but on the power to observe with care—should be produced and selected with caution. Such films should present only material that is visually and auditorily congruent. Lacking this congruency, the films may teach what is said, not what is seen, a procedure that defeats the very purpose of the film. This kind of film teaching may further authoritarianism and armchair “philosophy, ” and may weaken the habit of accurate observation, essential both to scientific methodology and to successful everyday living. It is difficult to compare the results of this study directly with the results of other studies, since—as Allen has pointed out (1)—there is a dearth of experimental research involving “flat” pictures. Hartman, however, recently commenting on the interference and facilitation between pictorial and verbal channels, pointed out that it is dangerous to assume a mutual strengthening (3). Results of the experiment reported here suggest again that the viewer when presented “equivocal” material gives precedence to audition. By thus accepting and remembering only the narrator’s point of view, he may narrow his own judgment and inquisitiveness. In such cases, silents please!  相似文献

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups.  相似文献
