Knowledge process capabilities are highly associated with innovation performance. Namely, firms which develop better capabilities in processing knowledge can innovate better. The Dynamic Capabilities view states that the effects of contextual variables on capability development cannot be ignored. This study seeks to examine the roles of two contextual variables; environmental dynamism and strategic flexibility on developing knowledge process capabilities and innovation performance. In parallel with this aim, a survey was conducted on a sample of 236 firms from different industries in Turkey and a number of hypotheses including the interaction effects of environmental dynamism and strategic flexibility were tested through moderated multiple regression methods. The three-way interaction of knowledge process capabilities, environmental dynamism and strategic flexibility was associated more strongly with innovation performance than the two-way interactions of knowledge process capabilities and environmental dynamism, and knowledge process capabilities and strategic flexibility. Hence, the findings revealed that the effectiveness of knowledge process capabilities on the way of enhancing innovation performance in highly dynamic markets were contingent upon strategic flexibility.

Objective To investigate the attitudes of the main stakeholders towards the introduction of sex education in schools in Russia. Design Qualitative semi-structured interview study. Setting Altai Krai, Volgograd Oblast, Moscow, Russian Federation. Participants One hundred and fifty-three interviews with Intersectoral HIV/AIDS Committee members, government officials responsible for HIV policies and interventions, non-governmental organisation and private-sector representatives. Main outcome measures Perception of and attitudes towards the introduction of sex education in schools. Results Ninety-one per cent of stakeholders welcomed the introduction of sex education in schools and emphasised its importance for a child's personal development, public health, sexually transmitted diseases and HIV/AIDS control, and pregnancy planning. The majority of respondents suggested providing different information for each age and grade. Despite the claimed support of interviewed policy-makers and main HIV stakeholders, there has been no action to introduce sex education. The majority of respondents were of the view that wider positive support through propaganda about health, sex and healthy lifestyle should be gained prior to introducing sex education in schools by addressing the stigma surrounding sexual issues. Conclusions There was little opposition to the introduction of sex education in Russian schools expressed in our survey, but there are uncertainties regarding curriculum quality, teaching methods and the starting grade of teaching about sex, and there is a need to cover local sensitivities in the territories. These concerns could and should be addressed during curriculum design, development and programme implementation by the federal and local authorities. Wider involvement of educational specialists, peer-adults, health workers, celebrities and religious representatives in discussion of the curriculum could help prevent opposition to its implementation. Contribution to knowledge Discussion of sex-related topics has been taboo in Russia and there has been little research into opinions on issues related to sex education. The contribution of this research is in gaining theoretical in-depth understanding of the attitudes of the interviewed stakeholders in Russia about the introduction of sex education in schools. 相似文献

Students use general web search engines as their primary source of research while trying to find answers to school-related questions. Although search engines are highly relevant for the general population, they may return results that are out of educational context. Another rising trend; social community question answering websites are the second choice for students who try to get answers from other peers online. We attempt discovering possible improvements in educational search by leveraging both of these information sources. For this purpose, we first implement a classifier for educational questions. This classifier is built by an ensemble method that employs several regular learning algorithms and retrieval based approaches that utilize external resources. We also build a query expander to facilitate classification. We further improve the classification using search engine results and obtain 83.5% accuracy. Although our work is entirely based on the Turkish language, the features could easily be mapped to other languages as well. In order to find out whether search engine ranking can be improved in the education domain using the classification model, we collect and label a set of query results retrieved from a general web search engine. We propose five ad-hoc methods to improve search ranking based on the idea that the query-document category relation is an indicator of relevance. We evaluate these methods for overall performance, varying query length and based on factoid and non-factoid queries. We show that some of the methods significantly improve the rankings in the education domain. 相似文献

This paper explores the educational and migrational pathways which a number of middle-class women from Bangladesh took as they grew up in the 1980s and 1990s. It draws on qualitative research, conducted between July and November 2011, with highly educated Bangladeshi women who migrated to Britain in the early 2000s. French Sociologist Pierre Bourdieu's critique of education, as a means of middle-class social reproduction [Bourdieu, P., and Jean-C. Passeron. ([1977] 1990). Reproduction in Education, Society and Culture. 2nd ed. Translated from the French by Richard Nice. London: Sage], and his notion of ‘academic capital’ [Bourdieu, P. 1984. Distinction: A social Critique of the Judgement of Taste. Translated from the French by Richard Nice. London: Routledge; Bourdieu, P. 1986. “The Forms of Capital.” In Handbook of Theory and Research For the Sociology of Education, edited by J. G. Richardson, 241–258. New York: Greenwood] are applied to this empirical data. While the participants’ experiences of early education confirms Bourdieu's arguments, in terms of the centrality of the family's educational and cultural capital in making a qualitative difference to their children's academic achievements, the analysis of the participants’ higher education complicates this picture. Here, the paper calls Bourdieu's umbrella term ‘academic capital’ into question. The author suggests that three categories of academic capital were needed to explain the different and unequal ‘value’ of the participants’ academic qualifications before and after migration. These are – elite, standard and general. Through this exploration of these women's educational and migrational pathways, and the classed and gendered nature which many of them took, this paper seeks to further the feminist project of making Bourdieu's theories ‘useful’ in understanding contemporary issues which affect women's lives (Adkins, L. 2004. “Introduction.” In Feminism After Bourdieu, edited by L. Adkins and B. Skeggs, 110–128. Oxford: Blackwell, 3). 相似文献

Caching is a crucial performance component of large-scale web search engines, as it greatly helps reducing average query response times and query processing workloads on backend search clusters. In this paper, we describe a multi-level static cache architecture that stores five different item types: query results, precomputed scores, posting lists, precomputed intersections of posting lists, and documents. Moreover, we propose a greedy heuristic to prioritize items for caching, based on gains computed by using items’ past access frequencies, estimated computational costs, and storage overheads. This heuristic takes into account the inter-dependency between individual items when making its caching decisions, i.e., after a particular item is cached, gains of all items that are affected by this decision are updated. Our simulations under realistic assumptions reveal that the proposed heuristic performs better than dividing the entire cache space among particular item types at fixed proportions. 相似文献
