Price-setting newsvendor with strategic consumers

We consider a newsvendor who sells a single product over a single season with the objective of determining both the selling price and stock quantity to maximize the expected profit. The customers are strategic and we consider two demand cases: additive and multiplicative. For each case, we derive the newsvendor׳s optimal decisions and demonstrate that neglecting the price-sensitivity of demand leads the newsvendor to make sub-optimal decisions. Moreover, we show that under certain conditions, strategic consumer behavior may positively affect the newsvendor׳s optimal expected profit in the additive demand case.     

The “Silent Dog” Method: Analyzing the Impact of Self-Generated Rules When Teaching Different Computer Chains to Boys with Autism

The purpose of the study was to extend the literature on verbal self-regulation by using the “silent dog” method to evaluate the role of verbal regulation over nonverbal behavior in 2 individuals with autism. Participants were required to talk-aloud while performing functional computer tasks.Then the effects of distracters with increasing demands on target behavior were evaluated as well as whether self-talk emitted by Participant 1 could be used to alter Participant 2''s performance. Results suggest that participants'' tasks seemed to be under control of self-instructions, and the rules generated from Participants 1''s self-talk were effective in teaching computer skills to Participant 2. The silent dog method was useful in evaluating the possible role of self-generated rules in teaching computer skills to participants with autism.

The Making of COBRS 2.0

Abstract

Recently introduced advances in microcomputer technology offer opportunities for improving child welfare agencies' access to powerful case assessment and program evaluation tools. This paper discusses the process of fitting a child behavior outcome measurement system to a menu driven microcomputer program. Traditional strategies for measuring outcome effectiveness, managerial priorities and operational constraints are examined in terms of their bearing on the introduction of new microcomputer technology. The developmental process is traced to show how these factors influenced the addition of a number of user options to the basic program to enhance its adaptability to specific agency needs. Initial user feedback indicated general satisfaction with the basic program and the applicability of its output, little or no experimentation, as yet, in adapting the system, and, a minor need to adjust the sequencing of operator activities to better fit the realities of agency work rhythms.     

Classroom sex composition and first-grade school outcomes: The role of classroom behavior

Using nationally representative data from the Early Childhood Longitudinal Study-Kindergarten Cohort (N = 21,409; 10,452 girls and 10,957 boys; mean age = 7.24 years), the association between first-grade classroom sex composition (CSC), measured as the percentage of female students, and end of the year academic (reading, mathematics) and socio-emotional (externalizing problems, internalizing problems, self-control, interpersonal skills) outcomes was examined. Using multilevel modeling techniques and controlling for prior achievement levels, CSC was positively associated with children’s reading achievement at the end of first grade; students performed better in reading in classes with a higher percentage of female students. CSC was also associated with three of the socio-emotional outcomes; controlling for prior levels, students in classrooms with a higher percentage of girls had better self-control and interpersonal skills and fewer internalizing problems. Classroom behavior mediated the effects of CSC on reading achievement and the socio-emotional outcomes. Implications for the composition of first-grade classrooms are discussed.     

A Pilot Study of 2 Brief Forms of Dialectical Behavior Therapy Skills Training for Emotion Dysregulation in College Students

Abstract

Objective: To examine the feasibility and initial efficacy of 2 abbreviated dialectical behavior therapy (DBT) skills training groups: emotion regulation skills only and emotion regulation with mindfulness skills. Participants: Participants were 24 undergraduates (aged 18–29) with significant emotion dysregulation who participated between February and May of 2010, 2011, and 2012. Methods: Participants participated in 2-hour weekly group sessions for 8 weeks and completed outcome measures at baseline, midtreatment, posttreatment, and 4-week follow-up. Results: Participants in both conditions made significant gains, with large effect sizes, across measures of emotion regulation, affect, skills use, and functioning. There were no differences between the 2 groups, suggesting no additive benefit of mindfulness skills. Conclusions: This pilot study provides support for the acceptability and efficacy of abbreviated DBT skills training in colleges, given significant improvements, positive feedback, and low attrition. Impediments to feasibility included recruitment difficulties, particularly due to scheduling constraints.

Preschoolers' Attachment to Mother and Risk for Adjustment Problems in Kindergarten: Can Teachers Make a Difference?

Based on attachment theory, two aims were addressed. Firstly, we tested whether close teacher–child relationships may buffer children who are less securely attached to their mothers against negative outcomes, such as aggressive behavior. Secondly, our study evaluated whether teacher sensitivity may protect less securely attached children against forming less close relationships with their teachers. In a sample of 127 children, mother–child attachment was observed in preschool. In kindergarten, teacher sensitivity was observed, and teacher–child closeness and child aggressive behavior were rated by the teacher. Results of multilevel hierarchical regression analyses first showed that with high teacher–child closeness, less securely attached children are no longer at risk for more aggressive behavior. Secondly, it was found that with high teacher sensitivity, less securely attached children are no longer at risk for developing less close relationships with their teachers.     

民族地区乡村经济行为模式、动机体系及其变迁研究

民族地区乡村经济中的主导经济行为模式至少存在四种类型。民族地区人们的经济行为大致有三种基本的动机体系。改革开放以来,有五种主要因素在改变着这些经济动机体系和行为模式,一是乡(镇)政府、具有准政府性质的村集体组织以及其他各种组织的推动、示范和劝导作用,二是体制改革的推动或压力,三是文化移入的诱导或冲击,四是内部创新行为的出现,五是特定文化传承的激活。
