儿童期逆境与基因对男性服刑人员攻击性的影响

暴力再犯危险性评估是当今再犯危险性评估工作中的重点, 其中, 攻击性是服刑人员暴力再犯行为稳定的个体因素。对攻击性进行研究, 有助于预防和降低服刑人员在假释或出狱后的暴力再犯行为风险, 关系社会的长治久安。研究表明, 遭受儿童期逆境和携带易感基因(如MAOA-uVNTR低活性等位基因)是导致攻击行为的重要因素。但在现有的研究中, 儿童期逆境的计分方式局限于简单的线性加总, 或所依据的统计模型忽略逆境各维度之间的交互作用和非线性关系; 在服刑人员攻击性的评估中未考虑攻击性的亚类, 而且多使用自报告的量表测评, 这些问题制约了评估的有效预测力。本研究拟通过建立潜在类别模型, 分析男性服刑人员和普通成年人群在儿童期逆境上的亚类; 以实验与问卷测量结果、司法行为记录作为攻击性指标, 揭示儿童期逆境如何影响个体的主动性攻击、反应性攻击及暴力犯罪行为, 重点探讨儿童期逆境潜在类别对主动性攻击和反应性攻击的影响, 以及MAOA-uVNTR、COMT Val158Met、5-HTTLPR基因多态性在其中的调节作用。研究结果有助于找出高攻击性个体的生物遗传指标, 从而发现受儿童期逆境经历影响的易感人群, 为暴力行为的风险预测以及针对暴力攻击行为的行为矫正和相关药物设计提供理论和实证参考, 提高相关工作的效率。     

MCDM methods in strategic planning of forestry on state‐owned lands in Finland: applications and experiences

The forests in Finland have been under intensive planning for decades. Currently, mathematical programming is widely used in planning of wood production. Today's multi‐functional forestry, however, calls for more flexible decision support methods. MCDM tools have been used in responding to fresh planning challenges. For example, the Finnish Forest and Park Service, entrusted with the care of the vast majority of state‐owned natural resources in Finland, endeavours to produce large‐scale natural resource plans satisfying the needs of both economic, social, and ecological sustainability. Participatory approach is applied in the process. Several forestry applications of MCDM methods, particularly those making use of the AHP or the HIPRE program, have been presented. Also, the outranking methods ELECTRE and PROMETHEE have been tested. Due to the nature of forestry applications, statistical techniques for analysing uncertainties in pairwise comparisons and for utilizing interval judgement data have been developed to improve the usability of the AHP. Recently, a hybrid method called A'WOT, making use of the AHP and SWOT, was also introduced into strategic forest planning. This paper summarizes the experiences gained in applying a MAVT and two outranking methods in connection with a participatory natural resource planning process in Finland. In addition, some results of the method development work related to application needs are briefly presented. The details of the planning cases reviewed here have previously been presented in forestry journals. The purpose of this paper is not only to show how MCDM methods have been applied in forestry, but also to discuss the usability and usefulness of MCDM methods from the viewpoint of supporting forestry decision making—and how they might further be improved. Also, some perspectives for the future development work of MCDM applications in the field of natural resource management are focused on. As a conclusion, the use of more than just one MCDM method in a single planning process is seen usually recommendable. In addition, developing hybrid MCDM methods is regarded as a potential direction for future research. Also, closer co‐operation between method developers and appliers is called for to produce more useful applications. Copyright © 2002 John Wiley & Sons, Ltd.     

Factor Retention Using Machine Learning With Ordinal Data

Determining the number of factors in exploratory factor analysis is probably the most crucial decision when conducting the analysis as it clearly influences the meaningfulness of the results (i.e., factorial validity). A new method called the Factor Forest that combines data simulation and machine learning has been developed recently. This method based on simulated data reached very high accuracy for multivariate normal data, but it has not yet been tested with ordinal data. Hence, in this simulation study, we evaluated the Factor Forest with ordinal data based on different numbers of categories (2–6 categories) and compared it to common factor retention criteria. It showed higher overall accuracy for all types of ordinal data than all common factor retention criteria that were used for comparison (Parallel Analysis, Comparison Data, the Empirical Kaiser Criterion and the Kaiser Guttman Rule). The results indicate that the Factor Forest is applicable to ordinal data with at least five categories (typical scale in questionnaire research) in the majority of conditions and to binary or ordinal data based on items with less categories when the sample size is large.     

An experimental analysis of task refusal: A comparison of negative reinforcement contingencies and transitions between academic tasks

The purpose of the study was to do an experimental analysis of academic task refusal for one girl with a developmental disability. Task refusal was analyzed in two experimental analyses. First, an analysis testing if the behavior was maintained by negative reinforcement, and the second, an analysis testing if the behavior was the result of transitioning between academic tasks differing in preference. Task refusal did not occur in the demand condition of the functional analysis, indicating that the behavior was not maintained by escape from demands. Conversely, task refusal occurred solely in the second experimental analysis when transitioning from a high-preferred to a low-preferred academic task. In this case, the context of terminating a preferred academic task and transitioning to a less preferred academic task was aversive but not the demand itself. In addition, when an embedded break condition was compared to a no break condition in a multielement design, task refusal was reduced to zero levels.

Running as a way fat women re-story their bodies and construct a runner identity in a North American sociocultural context

AimThis research sought to identify the process by which women who identify as fat or as not having a typical athletic body construct an athletic identity and persist in their running and other athletic endeavors despite body size-related barriers.MethodsFrom an online recruitment effort, 19 North American women runners in larger bodies completed interviews in which they told the story of how they had become runners. A narrative analysis with a feminist, constructivist approach was conducted to identify story types.ResultsFour narrative types were identified: reclaiming the body, reclaiming health, space-making, and future-imagining. Through finding a size- and pace-inclusive running community, running persistently, and completing races, women relinquished the stories they’d believed that their bodies were not athletic since childhood and constructed an identity of runner in a fat body.ConclusionsThese women’s engagement in running is a personal form of resistance against those who define athletic and healthy as “thin” or “fit.” They have found a welcoming athletic community and have moved on to leadership where they are working to make running accessible to other women in bodies like theirs. Those reading these narratives should consider ways in which fat bodies have been excluded from athletics, as well as ways to support the work being done by women runners in fat bodies to redefine health and athleticism.     

A Cross-Domain Growth Analysis: Externalizing and Internalizing Behaviors During 8 Years of Childhood

In a sample of 405 children assessed in kindergarten through the seventh grade, we determined the basic developmental trajectories of mother-reported and teacher-reported externalizing and internalizing behaviors using cross-domain latent growth modeling techniques. We also investigated the effects of race, socioeconomic level, gender, and sociometric peer-rejection status in kindergarten on these trajectories. The results indicated that, on average, the development of these behaviors was different depending upon the source of the data. We found evidence of the codevelopment of externalizing and internalizing behaviors within and across reporters. In addition, we found that African-American children had lower levels of externalizing behavior in kindergarten as reported by mothers than did European-American children but they had greater increases in these behaviors when reported by teachers. Children from homes with lower SES levels had higher initial levels of externalizing behaviors and teacher-reported internalizing behaviors. Males showed greater increases in teacher-reported externalizing behavior over time than did the females. Rejected children had trajectories of mother-reported externalizing and internalizing behavior that began at higher levels and either remained stable or increased more rapidly than did the trajectories for non-rejected children which decreased over time.
