Putting the system back into systems change: a framework for understanding and changing organizational and community systems

Systems change has emerged as a dominant frame through which local, state, and national funders and practitioners across a wide array of fields approach their work. In most of these efforts, change agents and scholars strive to shift human services and community systems to create better and more just outcomes and improve the status quo. Despite this, there is a dearth of frameworks that scholars, practitioners, and funders can draw upon to aid them in understanding, designing, and assessing this process from a systemic perspective. This paper provides one framework--grounded in systems thinking and change literatures--for understanding and identifying the fundamental system parts and interdependencies that can help to explain system functioning and leverage systems change. The proposed framework highlights the importance of attending to both the deep and apparent structures within a system as well as the interactions and interdependencies among these system parts. This includes attending to the dominant normative, resource, regulative, and operational characteristics that dictate the behavior and lived experiences of system members. The value of engaging critical stakeholders in problem definition, boundary construction, and systems analysis are also discussed. The implications of this framework for systems change researchers and practitioners are discussed.     

从多元概化理论看高考综合能力测试的改进

通过多元概化理论的研究发现,高考综合能力测试（2001,广东）的总体信度达到了可以接受的水平（0.784）。但测验中各部分对总方差的贡献程度与预定的赋分比例有较大差距。其中,地理和政治的贡献度偏低,化学和历史的贡献度偏高。这表明有（历史和化学）偏科特点的考生得到了较高的综合分数。又经决策(D)研究发现,增加地理部分的题量会反常地降低测验的总体信度,这说明有不少高分考生答错或主动放弃了地理科题目。因此,如何有效控制各部分的实际贡献程度、避免负面导向是当前高考综合能力测试亟待解决的问题。     

Sexual assault on college campuses: Is an ounce of prevention enough?

This article provides a construct-by-construct review of the effectiveness of sexual asault prevention programs in modifying sexual assault-related attitudes, cognitions, emotions, and behaviors. This article also discusses variables that may moderate program effectiveness, variables that may mediate program effectiveness, methodological issues, programs for special populations, and iatrogenic effects. In general, sexual assault prevention programs have been shown to be effective in producing short-term reductions in rape-supportive attitudes. There is insufficient evidence, however, to conclude that such programs are effective in reducing the incidence of sexual assault.     

The effects of intensive,extensive, structured study on GRE scores

Thirty-eight undergraduate students engaged in self-paced self-study using standard materials in one of five Graduate Record Examination (GRE) preparatory courses, lasting 5.5 to 7.5 weeks, offering 66 to 140 hours of study, and using attendance and participation incentives. Statistically and practically significant improvements were found from pretest to posttest verbal, quantitative, and combined scores. In one series of courses, the mean combined scores improved 96 points, increasing from 842 (pretest) to 938 (posttest). In the other, the mean improved 186 points, increasing from 888 to 1074. Earlier published research involved brief training (3 to 9 hours) and showed no benefits. The present research suggests that intensive, structured training can produce a mean improvement of at least 96 points, which is a socially significant accomplishment.     

Operant theory and methodology in infant vocal conditioning

The numerous mechanisms of behavior change in infant development are sometimes difficult to distinguish. Although it is agreed that elicitation and reinforcement both influence infant learning, the distinction between these two learning mechanisms was clarified in response to K. Bloom's (1984, Journal of Experimental Child Psychology, 38, 93-102) commentary. The theoretical and methodological assumptions of an functional analysis of infant behavior were made explicit in the context of the C. L. Poulson study (1983, Journal of Experimental Child Psychology, 36, 471-489). The rationale for the use of DRO schedules to control for elicitation effects of continuous reinforcement and the inadequacy of noncontingent schedules for this purpose were also discussed.     

The development of anticipatory hand orientation during infancy

The development of infants' prehensile adjustments regarding the orientation of objects was investigated. Five- and nine-month-olds (N = 16 per group) were presented with horizontally and vertically oriented dowels to determine at what point during the reach, hand orientation approximated that of the dowel. Nine-month-olds rotated their hands appropriately, early in the course of the reach, i.e., before tactual contact of the dowel, whereas five-month-olds did so mostly after tactual contact. Analyses of the effects of trials within the experimental session indicated that this age difference was not associated with practice or fatigue effects. The results are discussed in relation to the development of visual control of prehensile behavior.     

Resistance to yielding and the expectation of cooperative future interaction in negotiation

The expectation of cooperative future interaction (ECFI) encouraged especially high joint benefit (the total of the two bargainers' individual outcomes) when resistance to yielding was high, but especially low joint benefit when resistance to yielding was low. Process data suggest that this finding can be explained as follows: When resistance to yielding is high, ECFI encourages problem solving and reduced contentious behavior; when resistance to yielding is low, ECFI encourages a collapse of aspirations. The results support Filley's (1975) dualconcern model and cast doubt on Deutsch's (1973) blanket assertion that a cooperative process leads to constructive conflict resolution.     

TV cameras,public self-consciousness,and mock juror performance

In Chandler v. Florida (1981), the U.S. Supreme Court ruled that the presence of television cameras in the courtroom does not violate a defendant's constitutional right to a fair trial. Since then, several states have expanded their TV coverage rights, and the controversy has intensified. The present study tested opponents' argument that TV cameras distract jurors, thereby reducing their reliance on evidence in the decision-making process. Fifty-one community adults watched a 95-min videotape of a civil trial in the presence or absence of a camera. No effects were obtained on verdicts, awards, or a series of self-report measures. The camera did impair subjects' recall of the evidence, but this effect was dually limited—(a) consistent with an adaptation hypothesis, an initially strong distractive effect gradually diminished, resulting in a net post-trial loss of information that was not statistically significant, and (b) consistent with an individual differences hypothesis, the camera impaired the recall of subjects who were low but not high in dispositional public self-consciousness. These findings were discussed in terms of their practical implications for courtroom management and their contribution to the self-awareness literature.     

Hearing your voice through bone and air: Implications for explanations of stuttering behavior from studies of normal speakers

Cherry and Sayers (1956) reported that stutterers have problems dealing with sound fed back to the ears through bone. Their experimental support for this claim is reexamined. It is shown that their technique does not produce the same bone-conducted feedback as produced by the speaker while speaking. Their results are reinterpreted as showing that stutterers have problems when speaking in the presence of low frequency sound because of its masking properties, rather than because the sound originates in bone-conducted feedback.     

Stuttering onset after laryngectomy

Two cases of onset of stuttering subsequent to laryngectomy are reported. These patients demonstrate that the existence of a larynx is not necessary for the generation of stuttering. The findings support the hypothesis that neuromotor control of sound source (laryngeal or alaryngeal) plays a critical role in the generation of stuttering-type dysfluencies and, perhaps, even in the onset of stuttering. They also suggest that dramatic alteration in sound source has the potential for dramatically altering fluency.
