Comparison of Hualapai school children to national norms on measures of receptive vocabulary and verbal ability

Performance differences on receptive vocabulary and general verbal reasoning ability of Hualapai Indians as compared to national norms were investigated. The Peabody Picture Vocabulary Test Revised and the Verbal portion of the Cognitive Abilities Test, Form 4 were administered to 206 Hualapai Indian children ranging in age from 5 years, 3 months to 15 years, 7 months. Their performance was compared at each grade level to the national norms for these measures. Results indicated that Hualapai children score significantly lower on both measures of verbal ability when compared to national samples. Results provide a long-needed archival record of the English language proficiency of the Hualapai, and support the notion of homogeneity of English language facility across American Indian tribes. Contributing factors to Hualapai and other Native American populations' weaker performance on measures of verbal ability are discussed.     

Protein and amino acids for athletes

The main determinants of an athlete's protein needs are their training regime and habitual nutrient intake. Most athletes ingest sufficient protein in their habitual diet. Additional protein will confer only a minimal, albeit arguably important, additional advantage. Given sufficient energy intake, lean body mass can be maintained within a wide range of protein intakes. Since there is limited evidence for harmful effects of a high protein intake and there is a metabolic rationale for the efficacy of an increase in protein, if muscle hypertrophy is the goal, a higher protein intake within the context of an athlete's overall dietary requirements may be beneficial. However, there are few convincing outcome data to indicate that the ingestion of a high amount of protein (2-3 g x kg(-1) BW x day(-1), where BW = body weight) is necessary. Current literature suggests that it may be too simplistic to rely on recommendations of a particular amount of protein per day. Acute studies suggest that for any given amount of protein, the metabolic response is dependent on other factors, including the timing of ingestion in relation to exercise and/or other nutrients, the composition of ingested amino acids and the type of protein.     

互联网时代大学生网络政治参与探微

随着互联网时代的到来,网络政治参与成为当今民主政治建设的一种新形式与新途径。通过对安徽省5所本科院校的大学生网络政治参与现状的调查,发现大多数大学生关心国家政治,愿意参政议政,大学生网络政治参与已成为民主政治建设的一支重要力量。受网络监管措施不力、自身政治素质不成熟等因素影响,大学生容易被网络上错误舆论诱导,导致盲从行为和群体极化现象。需要采取措施,加强网络监管,提高政府有关部门对大学生网络政治参与行为的反馈效率,以提高大学生政治参与的效能感,激发大学生更高的网络政治参与热情,使其积极发挥"正能量",为推进我国的社会主义民主政治建设作出重要贡献。     

零售商主导的闭环供应链效益分析

研究了零售商主导的闭环供应链回收渠道选择及定价决策问题。分析了集中决策模式及三种分散回收模式下的最优回收率、定价决策与系统效益。研究结果表明:在零售商主导的市场结构下,当制造商选择直接回收时,闭环供应链具有较低的销售价格和较高的回收率,制造商利润、零售商利润及系统总利润均最大,对消费者及整个社会更有利。

Who is schooled in developing countries? The roles of income,parental schooling,sex, residence and family size

This paper explores schooling determinants in Nicaragua. Results include: (1) schooling is determined simultaneously with number of children, although simultaneous estimates do not indicate sharp ‘quantity-quality’ trade-offs. (2) Rural boys receive less schooling than rural girls, possibly because of higher opportunity costs for boys in agricultural work. (3) Family background is quite important, suggesting limited intergenerational mobility. (4) Income has permanent and transitory effects. However, women's full income does not seem particularly important. (5) Parental schooling partially represents taste and genetic effects. Thus the interpretation of schooling as representing only efficiency is misleading and may lead to important distortions in the allocation of resources and ambiguous private welfare effects.     

Rural underpinnings for resiliency and linkages (rural): A safe schools/healthy students project

Rural Underpinnings for Resiliency and Linkages (RURAL) is an example of a Safe Schools/Healthy Students (SS/HS) project. RURAL provides services to children and families in a rural Kansas county. The county's rates of juvenile alcohol and illicit drug use are higher than state averages. The RURAL project was designed to enhance existing partnerships among three school districts, the local community mental health center, law enforcement, the regional prevention center, and Fort Hays State University. A significant number of evidence‐based strategies were implemented in the schools and community in a short period of time. Using a public health approach to increase school safety and promote healthy behaviors, RURAL introduced strategies designed to provide universal prevention for the school population, early intervention for at‐risk children and families, and intensive services for those with the greatest needs. Services were provided to students (preschool–young adults) and their families. School psychologists held key roles in the development, implementation, and management of the project. Preliminary evaluation findings are presented, and the importance of local process and outcome evaluation is discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 531–547, 2003.     

Emotion and cognition: an intricately bound developmental process

Regulatory aspects of development can best be understood by research that conceptualizes relations between cognition and emotion. The neural mechanisms associated with regulatory processes may be the same as those associated with higher order cognitive processes. Thus, from a developmental cognitive neuroscience perspective, emotion and cognition are dynamically linked and work together to process information and execute action. This article highlights the authors' recent efforts at integrating emotion regulation and cognitive processing during the first year of life by focusing on the methodological criteria outlined by Cole, Martin, and Dennis (this issue), and it discusses the idea that emotion and cognition are an intricately bound developmental process.
