Performance of Fourth-Grade Students with Learning Disabilities on Multiplication Facts Comparing Teacher-Mediated and Technology-Mediated Interventions: A Preliminary Investigation

Instructional applications (apps) are educational software programs that can be accessed via mobile technologies (e.g., iPad, smartphone) and used to help students acquire various academic skills, including mathematics. Although research suggests that app-based instruction (AI) can be effective, there is a paucity of research comparing AI, to teacher-directed instruction (TDI) or to a combination of instructional approaches (CI) involving both AI and TDI in tandem. In an alternating treatments design, we compared AI, TDI, and CI conditions during instruction targeting multiplication facts with six students with learning disabilities. Results were inconsistent across students, and no condition emerged as consistently better than the others. Students completed social validity rating scales, and all approaches were favored by at least one student. Our results support findings from previous research involving similar comparisons between these instructional formats in which no (or minimal) differences across conditions were detected. We conclude that there may not be a meaningful difference between the outcomes achieved using AI, TDI, or CI for many students. Results are discussed in terms of directions for the future research.     

The Relative Importance of Personality,Financial Satisfaction,and Autonomy for Different Subjective Well-Being Facets

Abstract

Using a nationally representative sample (N?=?507) from Singapore, this study examined whether personality, financial satisfaction, and autonomy were important to subjective well-being (SWB), and how the importance of these predictors varied across different SWB facets—life satisfaction, happiness, positive feelings, and negative feelings. The findings indicated that neuroticism, financial satisfaction, and autonomy, were important predictors of happiness. Personality was most important for affective well-being (i.e., positive and negative feelings), whereas financial satisfaction was most important for life satisfaction. Specifically, neuroticism accounted for substantial variance in positive and negative feelings, and was the strongest correlate among the Big Five traits. In contrast, financial satisfaction explained most of the variance in life satisfaction. This highlights that the importance of well-being predictors depended on the facet of well-being examined. The findings suggest that residents in an affluent nation like Singapore do not emphasize only postmaterialist values (e.g., autonomy) and disregard materialist concerns (e.g., financial satisfaction). Though certain SWB facets (positive and negative affect) are largely influenced by dispositional factors, other facets (life satisfaction and happiness) are closely related to factors (e.g., financial satisfaction, autonomy) that may be affected by social policies. Policymakers can thus target those aspects to enhance people’s SWB.     

儿童社会认识论:儿童对信息提供者的选择性信任

个体掌握的知识很多来自于他人的传授。从4岁起,儿童就意识到不同的信息提供者在可靠性上存在差异。他们根据与提供者间的熟悉程度、提供者过往陈词的准确性、以及来自他人的线索等策略对于信息提供者的可靠性进行评估,从而决定谁更值得信任。未来关于儿童对于信息提供者选择性信任的研究应从扩展探究的知识领域、对于信息提供者其他特征的操纵、以及潜在文化差异检验等方面进行。     

物理温度向社会情感的隐喻映射:作用机制及其解释

基于概念隐喻理论的视角,大量行为与神经层面上的研究都揭示了温度与社会情感之间的隐喻关联有着更深层次的心理意义.“隐喻一致性效应”与“隐喻补偿效应”被用来阐述温度-社会情感隐喻的作用机制.而个体早期经验的不断“架构”构成了对这一隐喻形成的解释.此外,神经层面的研究也发现,脑岛可能是物理温度向社会情感隐喻映射的神经基础.未来的研究需从完善研究方法、深化作用机制、从发展的角度探索形成机制的研究以及注重温度-社会情感隐喻研究的应用拓展等几个方面着手.     

What it means to be and feel like a "true" American: perceptions and experiences of second-generation Americans

Through semistructured interviews, the authors investigated the relationships between the definition of a "true" American, the impact of 9/11, and the war in Iraq and their impact on experiences of fitting into and being excluded from the American identity with a sample of 10 2nd-generation young adults. Using consensual qualitative research methods (C. E. Hill et al., 2005; C. E. Hill, B. Thompson, & E. N. Williams, 1997) the authors identified 6 major domains that described participants' experiences, including physical characteristics of true Americans, behavioral characteristics of true Americans, beliefs and values of true Americans, the impact of 9/11 on definitions of true Americans, participants' American identity, and experiences as 2nd-generation Americans.     

Reasoning about the disclosure of success and failure to friends among children in the United States and China

Children's reasoning about individuals' willingness to disclose their successes and failures was investigated among 194 6- to 11-year-olds in the United States and China. In Study 1, participants showed a valence-matching effect, in which they predicted that individuals would be more likely to disclose their performance to an audience of friends if the friends' level of achievement was similar rather than dissimilar. This effect was weaker among children from China, who were more likely to justify their responses with reference to the implications for learning together or improving future performance. Results of Study 2 suggest that for children from the United States, the disclosure of successful performance to a friend who has performed poorly is seen as implicitly conveying the message "I'm better than you," whereas for children from China the message is "I can help you to do better." Results are interpreted with reference to cultural values and expectations about helping others to learn.     

ACC／AHA成人慢性心力衰竭诊疗指南的评解

美国心脏病学会／心脏学会（ACC／AHA）于2005年底对2001年的成人慢性心力衰竭（心衰）诊疗指南进行了更新。该指南不仅延用了过去的纽约心脏病学会（NYHA）心功能分级,而且采用了心脏病病程分期,对于准确估计心脏病程度、指导临床治疗和评估预后有重要的价值。该指南不仅进一步肯定了神经内分泌拮抗剂在心衰治疗中的地位,同时确立了器械治疗在心衰中的应用价值。

儒家道德形而上学问题探究

道德形而上学,主要解释了道德的普遍性与必然性的原理,它是道德哲学的基本问题之一.在儒学的构成中,道德问题是贯穿其整个学说的主线,自然也留下了大量关于道德形而上学的系统论述.经历了先秦时期的萌芽,宋明时期的发展,直至近现代的完善,儒家道德形而上学理论生成了自身独具的结构范式.它通过对非感性世界的追问,为人们的道德生活与意义世界提供了源于生命内在自我领悟的终极关怀.它从根本上决定了儒家道德理想、道德原则、道德评价、道德规范、道德序列以及道德修养的内涵.     

Standing between two worlds in Harlem: A developmental psychopathology perspective of perinatally acquired human immunodeficiency virus and adolescence

Perinatal HIV infection in the US continues to evolve from a fatal pediatric illness to a chronic medical condition of childhood and adolescence. Although navigating this period is influenced by multi-leveled deprivations commonly experienced by low-income minority families, HIV alters the timing and experience of developmental milestones for many adolescents with perinatal HIV. This selective review of the growing developmental psychopathology literature and the authors' clinical work at a pediatric HIV program in Harlem, NY provide an overview of how developmental psychopathology offers an integrative framework that elucidates how autonomy, peer relationships, and self-concept evolve among 13–21 year old adolescents. This paper highlights the importance of considering influences of both perinatal HIV and the culture of poverty on adolescent development, and of adopting multilevel interventions and research to address how interactions among biologic, environmental, and HIV-related stressors (serostatus disclosure, medical treatment adherence, illness stigma) influence the development of adolescents with perinatal HIV.
