A path-analytic study was undertaken to investigate the proposed relationship between physical attractiveness, need for intimacy, self-disclosure, thought about one's dating partner, and reported romantic love. Extrapolations from theories by Murstein (1971) and I. Reiss (1960), and conclusions from other empirical work, provided the background for the assessment of the relationship between the four proposed predictive factors and the development of romantic affect. During the winter of 1977-78 656 college students responded to a survey assessing each of the four predictors and romantic love. Path structures were initially estimated for male and female subsamples. Since few significant sex differences were noted, coefficients were compared for groups of students involved in dating relationships of varying durations. All four predictors were significantly associated with the subjects' self-reported romantic affect toward their dating partner. In all analyses, thinking about one's partner was found to be the most potent predictor. The data suggest the earlier work by Murstein and Reiss offer both testable and productive theoretical foundations for the study of romantic involvement. However, in future work it would be beneficial to (a) search for more numerous and powerful antecedents to romantic love; (b) delineate the specific role of cognitive processes in influencing romantic attachment; (c) compare relationships on criteria other than months of involvement; and (d) seek to examine love from the perspectives of both individuals involved in the dyadic relationship.Received her Ph.D. from the Pennsylvania State UniversityReceived his Ph.D. from The Pennsylvania State University.  相似文献

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.  相似文献

Intuitively, a hand held in close proximity to a firearm at the instant of discharge will intercept a significant amount of gunshot residue, even though the hand did not actually come into contact with the weapon. There is, however, little information specifically described in the forensic science literature concerning the residue levels which might be encountered in such an instance. The present work confirms that antimony levels consistent with an individual having fired or handled a firearm may be intercepted by a hand held in close proximity.  相似文献

The purpose of this paper is to explore the “critical thinking” approach to teaching and develop those concepts into meaningful instructional activities in the classroom. The authors offer practical suggestions based on the critical thinking philosophy for implementing an active learning approach. The case study method serves as the foundation for an investigative process course and lead-up activity to the simulated preliminary and follow-up investigation. The instructor presents the critical thinking process and content information that enables students to perform five basic progressions: (1) case studies; (2) the preliminary investigation; (3) follow-up; (4) suppression hearing; and (5) moot court criminal justice simulations.  相似文献

Interviews were conducted with 60 young people aged 12–19 in Australia, concerning their views about parenting and financial arrangements after separation. Half the young people reported that they had no say at all in where they would live after separation. A quarter said they were never able to see their nonresident parent when they wanted to. There was a strong relationship between young people's perceptions of the fairness of the parenting arrangements and the extent to which they were allowed to participate in making those arrangements. Half said that they did not have enough time with their nonresident parent. Having a continuing and meaningful relationship with both parents and with siblings was very important to them. More than a third favored arrangements of spending equal time with each parent. The young people were also very concerned with issues about fairness between first and second families, both in terms of time availability and financial provisions.  相似文献

Disasters such as flash flooding, mass shootings, and train and airplane accidents involving large numbers of victims produce significant opportunity for research in the biosciences. This opportunity exists in the extreme tails of life events, however, during which decisions about life and death, valuing and foregoing, speed and patience, trust and distrust, are tested simultaneously and abundantly. The press and urgency of these scenarios may also challenge the ability of researchers to comprehensively deliver information about the purposes of a study, risks, benefits, and alternatives. Under these circumstances, we argue that acquiring consent for the immediate use of data that are not time sensitive represents a gap in the protection of human study participants. In response, we offer a two-tiered model of consent that allows for data collected in real-time to be held in escrow until the acute post-disaster window has closed. Such a model not only respects the fundamental tenet of consent in research, but also enables such research to take place in an ethically defensible manner.  相似文献
