Reading disability in boys and girls: No evidence for a differential genetic etiology

In order to test the hypothesis that genetic influences are moreimportant as a cause of reading disability in girls than in boys,composite reading performance data from identical and fraternal twinpairs were analyzed using both concordance and multiple regressionmethods. The sample included 206 identical (99 male, 107 female), 159same-sex fraternal (90 male, 69 female), and 117 opposite-sex fraternaltwin pairs, in which at least one member of each pair had readingdifficulties. Although the difference between the concordance rates forreading disabilities in female identical and same-sex fraternal twinpairs was somewhat greater (65% for identical twins vs.32% for fraternal twins) than the difference in concordance ratesfor boys (68% vs. 39%), loglinear analysis of thesecategorical data revealed that the interaction between sex, zygosity,and concordance was not significant (p > 0.70). Moreover,the heritability of reading disability(h ² _g) estimated from regression analysisof the reading performance data in males was nearly identical to that infemales (h ² _g = 0.58 and 0.59,respectively; p > 0.90). Thus, results of this studyprovide little or no evidence for the hypothesis of greater geneticinfluence on reading difficulties in girls than in boys.     

ICTs in the Rush Hour of Life

In the Netherlands, many women have entered the labor market in the last two decades. This development - among other social changes - has resulted in substantial shifts in the time that Dutch people spend on paid labor and "caring tasks" on the one hand and leisure activities on the other hand. This task combination has caused serious time pressure and coordination problems among dual-income families with children. Therefore, it is not an exaggeration to label this stage of life as the "rush hour of life". In this article the findings of a small-scale qualitative case study among these "busy" households are presented. The objective of this study is to describe and analyze patterns of acceptance and use of information and communication technologies (ICTs), especially telecommunication technologies, in the context of the everyday life of these households. The question is raised whether ICTs can be a solution to time pressure and coordination problems. Theoretically, the research is rooted in a user-oriented perspective toward technological innovation, developed in the United Kingdom by Silverstone, Haddon, and others, which understands the incorporation of ICTs into the everyday life of households as a "domestication process". A paradoxical conclusion of this study is that ICTs are not explicitly perceived as solutions to the communication and coordination problems these households experience in everyday life, although they are being used for solving these problems. This ambiguity seems characteristic for the acceptance of ICTs in everyday life. The domestication concept is a useful concept to describe these ambivalent and paradoxical processes of (non)acceptance and use.

Study progress in therapeutic effects of traditional Chinese medicine monomer in severe acute pancreatitis

INTRODUCTION Severe acute pancreatitis (SAP) is one of the three main acute abdominal problems always ac-companied by multiple-system and multiple-organ impaired function or failure. Its onset and develop-ment are characterized by rapid changes, complicated illness state and difficult treatment. With the con-tinuous development of the traditional Chinese medicine industry in recent years, it is proved that traditional Chinese medicine (TCM) monomers monomers have a marked effect for …

改进的K-均值聚类排挤小生境遗传算法

针对基于罚函数的排挤小生境遗传算法的缺陷,提出了改进的K-均值聚类排挤小生境遗传算法。该算法将改进的K-均值聚类分析与排挤技术有机地结合起来,无需事先确定小生境的数目和半径,可以通过调节最小聚类距离控制收敛到的小生境的数目,避免找到无效的极值点。理论分析和数值实验表明,该算法对于非均匀分布的多峰函数具有较好的搜索性能。     

Brazil in the Age of Electronic Commerce

E-commerce is growing rapidly in Brazil, led by information-intensive and transaction-intensive sectors such as finance, manufacturing, and retail/wholesale. However, Brazil's highly uneven income distribution is a major barrier for B2C diffusion. Government policies have emphasized promotional or enabling initiatives such as e-procurement, tax filings, and providing Internet access to social institutions. E-commerce legislation is just now being developed, and decisions on taxation are being negotiated in the context of international agreements. E-commerce raises issues for Brazil in terms of its relationship to the global economy. Although most online purchases involve imported goods, e-commerce also offers opportunities to participate in international value chains.     

The intra-active production of normativity and difference

Drawing on memory stories told in a collective biography workshop about children’s encounters with schooling, this paper experiments with re-imagining the child-student-subject as an ‘emergent intracorporeal multiplicity’ [Fritsch, K. 2015. “Desiring Disability Differently: Neoliberalism, Heterotopic Imagination and Intra-Corporeal Configurations.” Foucault Studies 19: 43–66, 51]. From the feminist new materialist perspective that the authors work with, the child is configured not as an entity prior to, or separate from, encounters with education systems, but emergent with-in them. This paper focuses on difference in human relations, and in particular on the intersections of disability and gender. It does so not in terms of essential characteristics of individuals, but as emergent, in-the-moment, with others. In focussing on the detail of lives-in-their-making, the authors ask, with Barad [2007. Meeting the Universe Halfway: Quantum Physics and the Entanglement of Matter and Meaning. Durham: Duke University Press], if we are interested in justice, how we are to ‘understand our role in helping constitute who and what come to matter?’
