Joshua Lederberg will surely be remembered for his stellar contributions to microbial genetics and his sage intervention in
public affairs concerning exobiology, infectious diseases, epidemiology, and bioterrorism. Not so well know is his emphatic
mission to spell out that bacteria are cells and not something else. This brief sketch examines some of his contributions
to bacterial cytology.
Moselio Schaechter (Elio to friends) spent his career studying growth physiology and cell structure of enteric bacteria. Born
in Italy, he spent his youth in Ecuador before going to the United States where he chaired the Department of Molecular Biology
and Microbiology at Tufts University in Boston for twenty three years. After retirement he is at San Diego, where he has devoted
himself to sharing the excitement of the microbial world, mainly via a blog called “Small Things Considered”. He has authored
several influential textbooks and reference works. He succeeded Joshua Lederberg as Editor-in-Chief of the Encyclopedia of Microbiology. He also authored a book, In the Company of Mushrooms, which deals with his avocation, wild mushrooms. 相似文献

This paper arose amongst the making and showing of a film and questions whether there are possibilities for interrupting powerful discursive frames that work at producing ‘the normal child’. Traditionally there has been a lack of interest in the use and critique of visual culture in educational research. Perhaps this lack of interest provides fertile opportunities to know something of the structure of education as a discipline, the rules that structure it and its deep grammar; it may also open up opportunities for disciplinary boundary-crossings where fields that embrace visual culture, such as photography and filmmaking, can bring their playfulness across binaries, including notions of certainty/ambivalence, to qualitative research in education. By turning to art theory, our aims are to interfere with our utopian longings that steadfastly cling to educational notions of the child. 相似文献

This paper explores the responses of nearly 1200 children and young people in Wales who were asked to identify which three famous people they most admired and which three they most disliked. Analysis of these young people's responses reveals a number of sociological and educational issues. Their selections confirm other research which has highlighted the importance of celebrities in the lives of young people. Their ‘heroes’ and ‘villains’ are drawn mostly from the worlds of popular music and sport. Their choices are also highly gendered and ‘raced’. Of particular interest is the finding that someone's ‘villain’ is more than likely to be someone else's ‘hero’. Our young people's selection of heroes and villains reflects the broader landscape of celebrity culture, where female fame is as much about appearance as talent and Black and minority ethnic celebrities are to be found largely in the fields of sport or popular music. The paper concludes by discussing the chasm between our young people's ‘heroes’ and ‘villains’ and those which are ‘officially sanctioned’ within the school curriculum and considers what schools and teachers might do about it. 相似文献

In England, Scotland and other countries, policy‐makers often depict the targeted recruitment of men to the teaching profession as a panacea for male underachievement and disaffection from school. It is commonly assumed that the gender gap in achievement stems from the dearth of male role models in teaching, especially at primary level. Giving particular attention to recent literature on the influence of teacher gender on classroom interaction and educational outcomes, the paper begins by scrutinizing the policy's evidence‐base. We move on to examine the findings of a qualitative study conducted in English primary schools. Drawing upon data from semi‐structured interviews with teachers of 7‐ to 8‐year‐olds (25 men, 26 women), an attempt is made to assess their responses to the policy of targeted male recruitment and perceptions of the benefits of same‐gender matching. The paper (an earlier version of which paper was presented at the European Educational Research Association's Annual Conference at the University of Ghent, September 2007) concludes by tentatively exploring the implications of this small‐scale study for policy and practice. 相似文献

The present paper describes a study in which 13 children aged 9–11 years, of diverse ethnic, linguistic, and socio‐economic backgrounds, were asked to use a digital camera and small notebook to document the range of things they consider to be healthy and unhealthy. Using open‐ended interview questions, the children were then asked to explain each item, including what it was, why they chose it, and why they thought it was either healthy or unhealthy. The range of definitions of ‘healthy’ and ‘unhealthy’ invoked by the children was surprisingly broad, encompassing not only illness and proper nutrition, but also environmental health, mental health, cleanliness, and other meanings. Findings across all 13 children are displayed, and a case study of one child serves as a detailed example of the types of meanings children ascribe to the words ‘healthy’ and ‘unhealthy’, as well as the kinds of analyses being employed on these data. The theoretical implications of these results for research on children’s ideas about health, as well as implications for the design of health interventions, are discussed. 相似文献

Even though choice is not officially a feature in the German primary school system, some parents intervene in determining which school their child attends. Especially in urban contexts, the informal school market is growing. This demand is based on promises with respect to a certain quality of education as well as on issues that prevail in certain inner city schools. In looking at Berlin, as a global city, this article shows how contrary school choice practices gain traction in the face of ‘cultural differences’ that those practices produce discursively. Cultural semantics are activated with regard to the composition of the student body, when parents chose schools with a bilingual profile, but also when parents engage in the practice of ‘group enrolment’ into schools in inner city hotspots perceived as problematic. Our research shows how school choice practices may become acceptable despite being a public taboo, if parents argue by appeal to ‘cultural differences’. 相似文献

Abstract The term ‘pastor’ clearly has a religious origin and is thought of in connection with providing spiritual sustenance. Such provision must be seen in relation to some concept of authority since the pastor's job could otherwise not be done. It is likely that the connotation of a pastor in the religious sense has been carried over to the schools, especially when it is considered that schools are traditionally structures of authority. What is necessary is to insist upon the conceptual link between ‘pastoral care’ and ‘authority’ explicitly, so as to judge the final appropriateness of ‘pastoral care’ in schools. 相似文献

Whilst it is known that Caribbean girls academically outperform boys, much less is known about their experiences of school. This paper, based on qualitative research in Antiguan secondary schools, is concerned with who girls can ‘be’ in their school contexts and the consequences of positioning oneself (or being positioned) within different discourses. Drawing on interview narratives and classroom observations, this paper discusses the stories of six girls to illuminate three broad types of gender performances that were observed: ‘beauties’, ‘geeks’ and ‘men-john’. Using Francis' concepts of gender ‘monoglossia’ and ‘heteroglossia’, the extent to which these girls were able to resist the normative gender–sexual order and the consequences of conformity/non-conformity are examined. 相似文献

This paper reports upon a research project which considered the transfer of students' mathematical understanding across different task contexts. The research involved two groups of students from contrasting learning environments. The first environment was characterised by the complete integration of mathematical process and content using open ended activities. The second environment represented a typical English classroom with a content based scheme being predominantly used. The research demonstrated that the procedure and performance of students in response to addition and fraction tasks varied considerably when the context of the tasks changed. This variation suggested that students' perceptions of the contexts were individually constructed and contexts did not have a uniform effect upon the difficulty of tasks. The research also suggested that students who had learned in an environment characterised by the integration of process and content were more able to transfer their learning across contexts. Students who had learned mathematical process independently of content were more likely to vary their procedure and performance in response to the contexts of the tasks. This was considered in relation to the problems of school — real world transfer and the effectiveness of different learning environments. 相似文献

Education and the Contested Meanings of ‘Global Citizenship’ 总被引：1，自引：0，他引：1

This article examines the oftentaken-for-granted educational policy and curricular discourses of globalization and global citizenship within their larger cultural, political, and economically uneven histories and unequal consequences. Drawing upon evidence from recent scholarship on the implications for classroom pedagogy embodied inefforts to internationalize curricula in the North American university contexts, as well as specific related efforts in one Canadian context, the University of British Columbia,this article unpacks the contested meanings of global citizenship from above and below.The author analyzes three dominant curricular discourses of global citizenship. Far from weakening the Canadian state and building instances of transnational democratic educational communities, these dominant discourses may actually reinforce notions of Canadian gendered and racialized nation-building and nationalism. The article raises questions about what an alternative curricular and educational policy discourse from below premised upon efforts to decolonize curricula might look like. By way of provisional conclusion, the author discusses some promising examples of such an alternative,showing how they depend on seeing the relations between the local and global neither as fixed abstractions nor as a slogan system to be applied in absolutist racial, geographical,national, or culturally essentialist terms. 相似文献

Relying on ideas from practice theory and critical autobiography, I use this article first to tell, and then to analyse, a
story about trying to publish a book whose contents are in some ways marginal to what is normally considered science or science
education. During the publishing process, what counts as science got tangled up with what counts as “credible” science, “marketable”
literature, and academic competence. As a result, a book and a person (me) dedicated to expanding the boundaries of science
also became contributors to those very same boundaries. 相似文献

This paper presents some initial ideas on how the theoretical concepts of the ‘insider’ and the ‘outsider’ might be re-examined in an era where advances in comparative, qualitative research methodologies seek to be more inclusive, collaborative, participatory, reflexive and nuanced. Earlier essentialist definitions of the outsider as detached and objective, and the insider as culturally embedded and subjective, are re-examined and set within an international research and teaching context that recognises the increased migration of people, ideas and educational policies. It is argued that, in the context of such change, it has become more difficult to categorise and label groups and individuals as being ‘inside’ or ‘outside’ systems, professional communities or research environments. Such essentialist notions, which often underpin the production of large-scale, international datasets of pupil achievement, need to be challenged so that more complex understandings can inform not only new methods of research design, research ethics, data collection and analysis, but also the creation of new knowledge, giving more validity to related education policy making. We recognise that individual and group identities can be multiple, flexible and changing such that the boundary between the inside and the outside is permeable, less stable and less easy to draw. The concept of a ‘third’, liminal space may have the potential to encourage new meaning which is constructed on the boundary between worlds where historical, social, cultural, political, ethical and individual understandings meet. 相似文献

Barker argues that in England under New Labour, school leaders and teachers have been ‘bastardised’ and suggests that the situation in 2010, with a general election afforded an opportunity in education policy for the ‘pendulum to swing’. In this article, the key points about ‘bastard Leadership’ are briefly summarised. The article then develops a view of schools as sites of complexity and ‘wickedity’ as an alternative to the linear reductionist approaches of managerialists. These two perspectives present the extremes of a spectrum against which the trajectory of school leadership can be viewed as it emerges from the New Labour years and is now being developed by the Coalition Government. Evidence from ministerial speeches and the Coalition Government's flagship White Paper, The Importance of Teaching, are used to examine key issues of freedom and trust, reducing bureaucracy and increasing autonomy for schools as ways of exploring the extent to which the new government's policies on school leadership are, or are not, moving away from those of their New Labour predecessors. 相似文献

This study examines the beginning of the conceptual understanding of the first number-words and what role language can play
in developing the notion of numbers. To that end, 2?- and 3?-year-old Basque and Spanish monolingual children's (N = 131) basic numeracy skills are analysed by means of two different experimental procedures: Give-N (in which children are requested to gather sets of objects) and How-Many (based on the ability to count collections). The paper accounts for differences as regards the performance in the Give-N procedure between children with different linguistic backgrounds. In accordance with previous research, this finding can
be related to the dissimilar ways by which languages (Basque and Spanish, in this case) express grammatical number, supporting
the idea that language plays a definite role in the emergence of the earliest set-size meanings of ‘one,’ ‘two,’ and ‘three’
number-words. Eventually, the work attempts to contribute to the growing body of evidence that shows that the meaning of the
count-list appears from mapping numerals onto numerical cognitive representations produced by early core systems of numbers. 相似文献

This article mobilizes story-telling to narrate my lived experience of teaching English as a minority academic in one Australian university. Positioning myself as living ‘in-between’ two cultures and as an ‘Other’, I tell my story of how I have been ‘racialized’ and ‘Othered’ because I do not look White, and my spoken English is distinctly accented; hence, my legitimacy of teaching English is held suspect. My story contributes to the theorizing of the sociology of the in-between with the argument that while living in-between culture can be a space of negativity, it can also be a space of empowerment if one exercises choice and agency by forging new spaces. I end my story-telling with a happy ending by presenting a contrasting story of how my run-away from Australia to (a new space in) Hong Kong to teach English has reaffirmed my cultural capital as I morph into a different ‘Other’. 相似文献

Northern Ireland beginning teachers' experiences of induction: the ‘haves’ and the ‘have nots’ 总被引：1，自引：1，他引：0
The induction of beginning teachers continues to occupy a significant position on educational policy agendas as a crucial dimension in the formation of a teacher and one upon which an emergent career is built. Whilst there is growing impetus to establish an induction model that constitutes a relevant, fulfilling experience, current arrangements continue to vary throughout the UK. This paper describes induction as it affected a sample of beginning teachers in Northern Ireland, where there is a dearth of permanent positions for those newly qualified. Highly contrasting experiences of the induction year emerged between graduates in permanent and one‐year temporary positions, and those who were short‐term temporary and supply teachers. The former completed a meaningful induction whereas the latter, because of sporadic, fragmented employment, did not. A flexible model of induction is proposed, with collaborative involvement of the higher education institutions, the schools and the local education authorities. 相似文献

This article advances that the movement towards ‘deeper’ Caribbean integration has generated a shift from ‘immature’ regionalism to a ‘mature’ form of regionalism. Thus, mature regionalism, a new governance mechanism, in regulating the institutional and legal framework of Caribbean Single Market and Economy is drastically altering national education governance within the Caribbean Community. In focusing on the functional aspects integration, this article suggests that mature regionalism in education is built upon collaborative governance and encompasses multipartner governance arrangement – with the state, private sector, civil society, and the community as well as hybrid public–private and private–social partnerships and co-management regimes. It concludes that the instrumentalisation of mature regionalism in education is giving way to ‘educational regionalism’ defined by the movement towards structured institutional mechanisms, to facilitate the deepening of Caribbean integration. 相似文献
