Let's Talk About Race: Evaluating a College Interracial Discussion Group on Race

The authors evaluate Dialogues on Race, an interracial group intervention in which undergraduate student facilitators led conversations about race with their peers. The evaluation process is described, including developing collaborative relationships, identifying program goals, selecting measures, and analyzing and presenting results. The authors discuss lessons learned about evaluating an interracial dialogue intervention that did not originally include researchers in the hope that this examination will encourage others to evaluate similar campus interventions. Diálogos sobre Raza es una intervención de grupo interracial en la que estudiantes universitarios moderaron conversaciones sobre raza con sus compañeros. Se describe el proceso de evaluación, incluyendo el desarrollo de relaciones de colaboración, la identificación de objetivos del programa, la selección de medidas, y el análisis y presentación de los resultados. Los autores discuten las lecciones aprendidas sobre la evaluación de una intervención interracial dialogada que en principio no incluyó a investigadores con la esperanza de que este examen animará a otros a evaluar intervenciones similares en sus campus.     

Evaluation of a Web‐Based Alcohol Program Alone and in Combination With a Parent Campaign for Ninth‐Grade Students

This randomized controlled study evaluated the efficacy of a web‐based program alone and in combination with a parent campaign among 9th‐grade students (N = 205). Results indicate lower drinking rates in both programs compared with traditional education for female students.     

Addressing the needs of new mothers in a multi-cultural setting: an evaluation of home visiting support for new mothers – Mom to Mom (Negev)

This study evaluated the Mom to Mom (M2M) program operating in the Negev region of Israel, an area with a high proportion of immigrants. M2M helps women cope with the first year of parenting through home visits of volunteer mothers. Specific objectives were to evaluate (1) Participants’ motivations for joining M2M; (2) Gains from participation; and (3) The effect of participation on post-partum depression (PPD). Three stages included (1) Analysis of demographics of all 440 mothers in M2M; (2) A telephone survey of 51 mothers to assess gains from participation; and (3) 137 mothers filled out the Edinburgh Post-Natal Depression Scale (EPDS) and were followed for one year. Most mothers in M2M were first time mothers, with a high rate of perinatal complications (54.4%) and positive EPDS scores (38.7%). Two major reasons for participation were being an immigrant and having low income. The greatest gains from home visits were increased self-confidence, improved parenting skills and communication with the partner. Seventy-nine percent of mothers with PPD symptoms were functioning at work and at home after a year from joining the program. Our findings suggest that M2M has the capacity to address challenges in the post-natal period among women from diverse cultures.     

Strategies included in cognitive behavioral therapy programs to treat internalized disorders: a systematic review

This review aimed to identify the strategies used in programs based on cognitive behavioral therapy (CBT) to prevent and treat symptoms of anxiety, depression, and internalized behaviors of children and adolescents. Based on an online search (ERIC, PsycInfo, Virtuose UQAM, and Google Scholar), 61 studies describing different cognitive behavioral programs were selected. Results showed that 40 strategies were implemented in at least one program. However, none of the strategies were systematically present in all programs, and only few were reported in more than 50% of the studies. Cognitive restructuring and problem-solving were the most popular strategies to treat depressive symptoms, whereas anxiety programs also generally included relaxation and exposure. Furthermore, six strategies were identified in a single anxiety program, whereas nine strategies were implemented in only one depression program. These results suggest that in anxiety and depression programs designed for children and adolescents, the label “CBT” encompasses a wide variety of programs with only few similar strategies. Such findings highlight the need to define a common basis for CBT programs, in order to better reflect CBT theory and to identify the effectiveness of the strategies included in these programs.     

Theoretical and research support for the Duluth Model: A reply to dutton and corvo

In a recent article, Dutton and Corvo denounce and reject the so-called Duluth Model of batterer intervention based on cognitive–behavioral counseling, reinforcement from the criminal justice system, and coordination of additional community services. They not only accuse it of being ineffective and detrimental to progress in the field, but assert that its supporters are merely acting out of ideological and activist motivations. These authors call for research-based treatment that is more psycho-therapeutic in nature, along with a diminished role of the criminal justice system and more attention to women's violence. The authors, however, are highly selective in the research they use to substantiate their position and apply their own activist biases to its interpretation. Their portrayal of the Duluth Model, and the fundamentals it represents, is a distorted caricature of its current conception. There is psychological theory and criminal justice research that support the Duluth Model and its utility. Moreover, developments in the field contradict the claims that the Duluth Model has an “iron-clad” hold that is impeding progress. The categorical condemnations in the Dutton and Corvo article shut-off needed dialogue and debate rather than further those developments.     

面试考官的权重策略对评分和录用的影响

从个体水平研究面试考官的有效性是面试研究的一个热点问题．本研究对面试考官权重策略的类型及类型的比较进行了实证研究。研究运用线性规划策略捕捉方法,分析了公务员考试中28名考官在结构化面试和无领导小组讨论中的权重策略,研究了权重策略对评分和录用的影响,结果发现：（1）在结构化面试中存在三种策略,在无领导小组讨论中存在两种策略,这些策略大部分是规范的（符合评分规则的要求）,它们会随面试情景发生变化;（2）权重策略影响了考官的评分区分度和最终考生的录用结果,规范性策略具有较高的区分度和录用预测效度。研究最后对结果的理论和实践意义进行了讨论。     

A comparison of computational driver models using naturalistic and test-track data from cyclist-overtaking manoeuvres

The improvement of advanced driver assistance systems (ADAS) and their safety assessment rely on the understanding of scenario-dependent driving behaviours, such as steering to avoid collisions.This study compares driver models that predict when a driver starts steering away to overtake a cyclist on rural roads. The comparison is among four models: a threshold model, an accumulator model, and two models inspired by a proportional-integral and proportional-integral-derivative controller. These models were tested and cross-applied using two different datasets: one from a naturalistic driving (ND) study and one from a test-track (TT) experiment. Two perceptual variables, expansion rate (the horizontal angular expansion rate of the image of the lead road user on the driver’s retina) and inverse tau (the ratio between the image’s expansion rate and its horizontal optical size), were tested as input to the models. A linear cost function is proposed that can obtain the optimal parameters of the models by computationally efficient linear programming.The results show that the models based on inverse tau fitted the data better than the models that included expansion rate. In general, the models fitted the ND data reasonably well, but not as well the TT data. For the ND data, the models including an accumulative component outperformed the threshold model. For the TT data, due to the poorer fit of the models, more analysis is required to determine the merit of the models. The models fitted to TT data captured the overall pattern of steering onsets in the ND data rather well, but with a persistent bias, probably due to the drivers employing a more cautious strategy in TT.The models compared in this paper may support the virtual safety assessment of ADAS so that driver behaviour may be considered in the design and evaluation of new safety systems.     

Program Extraction from Normalization Proofs

This paper describes formalizations of Tait's normalization proof for the simply typed λ-calculus in the proof assistants Minlog, Coq and Isabelle/HOL. From the formal proofs programs are machine-extracted that implement variants of the well-known normalization-by-evaluation algorithm. The case study is used to test and compare the program extraction machineries of the three proof assistants in a non-trivial setting.     

Determinants and Barriers to Participation in an Internet Based Recovery Program for Cardiac Patients

Patients hospitalized for coronary heart disease were offered a home recovery program utilizing the Internet. About one-half of the patients interviewed chose to enlist in this program. Participants and non-participants did not differ significantly according to medical risk and diagnostic factors, lifestyle and some demographic variables (principally marital status, sex, and race). However, those who owned personal computers and/or were familiar with the Internet, who were in higher socioeconomic strata, and were younger than age 65 were strongly more likely to participate. Internet instruction and computers (for those who had none) were provided to participants. Those who were lent computers—29% of the program participants—were more often female, without any college training, and less confident about using the Internet. As the public becomes increasingly more familiar with personal computer technology these potential barriers to its use may eventually disappear. The present study evaluated a fairly resolute method to introduce an Internet program to many recovering patients who were unfamiliar with this technology. However, other innovative and perhaps more aggressive ways of making those most in need of such valuable health-related information and resources can be tested in the near future.
