胚胎发育畸形发生率的调查分析

胎儿在子宫内生长发育的时期大约需要10个月.从受精卵起到胚胎出离卵膜的这段过程叫做胚胎发育.在胚胎发育过程中,遗传物质的改变或环境因素的影响都会引起胚胎发育异常,导致流产或出生缺陷.在计划生育被人们普遍接受的今天,优生显得越来越重要.为了防止或减少先天性畸形和遗传性疾病患儿出生,及时阻断遗传病和各类畸形的发生,减少群体中有害基因的积累和传递,本文深入探讨新生儿畸形的发生率及其可能的病因,为防治提供依据.     

The Concept of Intelligence in Psychology as a Fallacy of Misplaced Concreteness

During the 20th century, mainstream psychologists exhibited a dogmatic belief in the reality of the abstraction of human intelligence as a cluster of functional behaviours. In confusing this abstraction for the concrete totality of the human intellectual experience, psychologists have committed what Alfred North Whitehead calls a "fallacy of misplaced concreteness" (1925/1967, p. 58). That is, they have mistaken a narrowly abstract conception of intelligence for concrete reality. This mistake has contributed to a dogmatic and naive ignorance of other possible explanations for intelligent human experience. If psychology truly desires to be a legitimate science in endeavouring to understand human intelligence, it must take into account concrete aesthetic experiences that are fundamental to the growth of creative consciousness and human knowledge.     

Educators confront the ‘science’ of racism, 1898–1925

The literature depicting educators’ role in scientific racism and eugenics during the early 20th century has tended to approach the topic in dichotomous terms, as an ideology that one was either for or against. In this historical study, the author adds some nuance to this literature by tracing leading educators’ inconsistent and evolving thoughts on eugenics and the ‘science’ of race. By approaching the educational discourse on race as thinking rather than thought, the author explores how scholars such as G. Stanley Hall, John Dewey, Franz Boas, William Bagley, David Snedden, Edward Thorndike and Charles Ellwood struggled to make sense of a rapidly changing ideological landscape, but nevertheless supported the ideology of white supremacy.

Awareness of Societal Issues Among High School Biology Teachers Teaching Genetics

The purpose of this study was to investigate how aware high school biology teachers are of societal issues (values, moral, ethic, and legal issues) while teaching genetics, genetics engineering, molecular genetics, human heredity, and evolution. The study includes a short historical review of World War II atrocities during the Holocaust when scientists from all the above-mentioned disciplines had been involved in trying to support and develop the eugenics theories. It investigates pre- and postwar theories of the eugenics movement in the United States which were implemented successfully in Germany and a literature survey of the studies of societal issues related to these subjects. The sample consisted of 30 male and female biology teachers. Enclosed are teachers' answers in favor or against including debates about societal issues in their classrooms while teaching the disciplines mentioned above. Teachers' answers were analyzed in relation to three variables: years of teaching experience, gender, and religion faith. Data were collected from questionnaires and personal interviews and analyzed according to qualitative and quantitative methods. The results show that amongst the teachers there is a medium to low level of awareness of societal issues, while mainly emphasizing scientific subjects in preparation of matriculation examinations. The majority of the teachers do not include societal issues in their teaching, but if students raise these issues, teachers claimed to address them. No differences in teachers' opinions to societal issues were found in relation to gender or religious faith. Teachers with more years of teaching experience tend to teach with a more Science, Technology, and Society (STS) approach than novice teachers. The results are discussed in relation to teachers' professional development and teaching strategies are suggested to be used in their classrooms based on a STS approach, which includes the societal issues as a main goal.

The errors of redemptive sociology or giving up on hope and despair

Abstract

This paper considers the sociology of education (SOE) as a modern human science. It suggests that the SOE is mired in a set of unreflexive, redemptive, Enlightment rationalities, and explores the messy relationships of the sociology with education that result from this. It is argues that the sociology of education has consistently failed to distance itself from the metaphysics, optimism and oppressions of modern schooling. That it has failed to call into question either the basic building blocks of schooling, or what we call education – pedagogy, curriculum and assessment – or the buildings themselves, the spaces of education. The paper concludes by asserting to need for critique rather than simply criticism as a starting point for thinking education differently.     

Sport,Science, and the Social Question in Early Twentieth-Century Argentina: An Analysis of Parliamentary Discussions, 1907–1924

This research reveals an unexplored aspect of Argentina’s sport policy-making process during the first three decades of the twentieth century. Contrary to the common assumption that little attention was paid to sport by early twentieth-century politicians, several bills proposing institutional support for the promotion and organization of national sport were presented in the Argentinean legislature. In order to support these proposals, many legislators resorted to medical and physiological discourse as the most important legitimizing force. Poverty, poor hygiene, and epidemic diseases, generated by rapid modernization and urbanization, urged some turn-of-the-century Argentine political elites to attempt a degree of social intervention within the general framework of the liberal-conservative order, as a way to counteract these evils and further advance the national progress enjoyed since the nineteenth century. In this context, sport was ardently advocated by some politicians as a means to raise scientifically the physical and moral constitution of the ‘Argentinean race’.
