The purpose of this study is to analyze variations in how the gene concept is used and conceived in different sub-disciplines
in biology. An examination of the development of subject matter and the use of the gene concept in a common college biology
textbook shows that the gene concept is far from presented in a consistent way. The study describes and categorizes five different
gene concepts used in the textbook; the gene as a trait, an information-structure, an actor, a regulator and a marker. These
conceptual differences are not dealt with in an explicit manner. This constitutes one of the sources for confusion when learning
about genes and genetics.

ABSTRACTField work programs have a substantial responsibility for providing support and gatekeeping functions while ensuring an educational experience that allows students to master the nine holistic, multidimensional social work accreditation competencies. With additional emphasis on field as a “signature pedagogy,” field directors are tasked with finding placements that can support these explicit competencies. Through the utilization of a learning contract that combines the Council on Social Work Education Educational Policy and Accreditation Standards competencies (including component behaviors) students and supervisors can begin to discuss their joint progress on meeting each of these prior to the final evaluation. This process will ensure that students have demonstrated the necessary outcomes to become a generalist social work practitioner. 相似文献

Conclusion This article has sought to highlight a work-experience programme in a Third World country, pin-pointing the factors that militate against the achievement of its desired objectives. Among such factors are problems associated with curriculum organization at the secondary level, not least the negative attitudes that the society generally has towards a practical curriculum. Inadequate funding, largely due to governments aloofness, against a background of pressure on schools to become more selfreliant; wastage of human resources in relation to programme organization; and the lack of effective communication both within the school system and between the school and the community generally-all these are proving to be constraints on the achievement of objectives. Our discussion lends support to Sinclair's (1977) observation, referred to earlier, that Third World countries lack the institutional framework for conducting real-world assignments by pupils in factories and offices. Before curriculum innovations like the WEP can have the desired effects, Third World countries will not only have to deal constructively with negative attitudes and values in relation to practical and manual labour, but they will also have to find ways of initiating employment-generating strategies, so that students who have been prepared for the world of work will have the opportunity to enjoy the right to work. In Third World countries like Jamaica, which are caught in the grip of political and social strife exacerbated by a vicious economic squeeze, these are gulfs which seem too wide to breach at present. 相似文献

It has previously been shown that measurement of the critical speed is a non-invasive method of estimating the blood lactate response during exercise. However, its validity in children has yet to be demonstrated. The aims of this study were: (1) to verify if the critical speed determined in accordance with the protocol of Wakayoshi et al. is a non-invasive means of estimating the swimming speed equivalent to a blood lactate concentration of 4 mmol x l(-1) in children aged 10-12 years; and (2) to establish whether standard of performance has an effect on its determination. Sixteen swimmers were divided into two groups: beginners and trained. They initially completed a protocol for determination of speed equivalent to a blood lactate concentration of 4 mmol x l(-1). Later, during training sessions, maximum efforts were swum over distances of 50, 100 and 200 m for the calculation of the critical speed. The speeds equivalent to a blood lactate concentration of 4 mmol x l(-1) (beginners = 0.82 +/- 0.09 m x s(-1), trained = 1.19 +/- 0.11 m x s(-1); mean +/- s) were significantly faster than the critical speeds (beginners = 0.78 +/- 0.25 m x s(-1), trained = 1.08 +/- 0.04 m x s(-1)) in both groups. There was a high correlation between speed at a blood lactate concentration of 4 mmol x l(-1) and the critical speed for the beginners (r= 0.96, P < 0.001), but not for the trained group (r= 0.60, P> 0.05). The blood lactate concentration corresponding to the critical speed was 2.7 +/- 1.1 and 3.1 +/- 0.4 mmol x l(-1) for the beginners and trained group respectively. The percent difference between speed at a blood lactate concentration of 4 mmol x l(-1) and the critical speed was not significantly different between the two groups. At all distances studied, swimming performance was significantly faster in the trained group. Our results suggest that the critical speed underestimates swimming intensity corresponding to a blood lactate concentration of 4 mmol x l(-1) in children aged 10-12 years and that standard of performance does not affect the determination of the critical speed. 相似文献

This paper proposes a novel query expansion method to improve accuracy of text retrieval systems. Our method makes use of a minimal relevance feedback to expand the initial query with a structured representation composed of weighted pairs of words. Such a structure is obtained from the relevance feedback through a method for pairs of words selection based on the Probabilistic Topic Model. We compared our method with other baseline query expansion schemes and methods. Evaluations performed on TREC-8 demonstrated the effectiveness of the proposed method with respect to the baseline. 相似文献

The tragedy of the digital commons 总被引:1,自引:0,他引:1
In the paper it is argued that bridging the digital divide may cause a new ethical and social dilemma. Using Hardin's Tragedy of the Commons, we show that an improper opening and enlargement of the digital environment (Infosphere) is likely to produce a Tragedy of the Digital Commons (TDC). In the course of the analysis, we explain why Adar and Huberman's previous use of Hardin's Tragedy to interpret certain recent phenomena in the Infosphere (especially peer-to-peer communication) may not be entirely satisfactory. We then seek to provide an improved version of the TDC that avoids the possible shortcomings of their model. Next, we analyse some problems encountered by the application of classical ethics in the resolution of the TDC. In the conclusion, we outline the kind of work that will be required to develop an ethical approach that may bridge the digital divide but avoid the TDC. 相似文献

Over the past few years there has been an increasing acknowledgment that all knowledge is "sited knowledge." While place, mobility, and travel have become central issues in the history (and geography) of science, much of the discussion has nevertheless revolved around "formal scientific knowledge." This essay focuses on a specific type of popular "mobile" scientific knowledge making that emerged in the last decades of the nineteenth century: the educational cruise. In particular, it considers a series of voyages d'etude organized by the French scientific periodical Revue Générale des Sciences Pures et Appliquées between 1897 and 1914 that were open to the general public. It examines both the ways and the spaces in which knowledge was produced and the type of knowledge that was produced. 相似文献
