Intergenerational Educational Mobility in Denmark     

Torill Tverborgvik  Lene Björk Clausen  Brian Larsen Thorsted  Sigurd Mikkelsen  Elsebeth Lynge 《Scandinavian Journal of Educational Research》2013,57(5):544-560

In light of the Danish government's goal of 95% of every cohort achieving higher education by 2015, we investigate educational mobility in Denmark. Following 800,000 Danes and their parents, we found that children of parents with only basic education had a three-times-higher risk of achieving only basic education, compared with the children of well-educated parents. These social differences in educational achievements were found despite free education and generous governmental grants and loans. We found general upgrading of a population's educational level to be a tardy process which implies breaking the bonds of negative social inheritance to increase intergenerational social mobility in the society; thus, the government's 95% goal is unlikely to be achieved by 2015.  相似文献   

Troubling the discourse of teacher centrality: a comparative perspective     

Marianne A. Larsen 《教育政策杂志》2013,28(2):207-231

The belief in the central role of the teacher has a long and comparative history. This article aims to critically analyse the discourse of the centrality of the teacher by both historicising and problematising the ideas and practices associated with this discourse. First, the article describes the discourse as it was taken up during the twenty‐first century when the teacher was viewed as the linchpin to building universal education systems. The idea that the ‘master makes the school’ is examined and the policies that stemmed from this thinking (e.g., the establishment of formal teacher training, teacher testing and certification) are outlined. The contemporary manifestations of this discourse are then described to show how the pervasive belief in the central role of the teacher has influenced education policy reforms, which like teacher policy reforms in the nineteenth century operate to shape and regulate the profession. Further discursive effects are analysed including the de‐contextualisation of educational reform and the de‐professionalisation and de‐politicisation of teachers and their work. The relationship between effective schools research and the centrality of the teacher discourse is also considered within the contemporary moment. This comparative study refers to the discourse of the centrality of the teacher in Australasia, Europe, Great Britain and North America, and suggests that our collective focus on the teacher has had some serious, unexpected effects on teachers and the work they do.  相似文献   

Inter and intra-document contexts applied in polyrepresentation for best match IR     

Mette Skov  Birger Larsen  Peter Ingwersen 《Information processing & management》2008

The principle of polyrepresentation offers a theoretical framework for handling multiple contexts in information retrieval (IR). This paper presents an empirical laboratory study of polyrepresentation in restricted mode of the information space with focus on inter and intra-document features. The Cystic Fibrosis test collection indexed in the best match system InQuery constitutes the experimental setting. Overlaps between five functionally and/or cognitively different document representations are identified. Supporting the principle of polyrepresentation, results show that in general overlaps generated by three or four representations of different nature have higher precision than those generated from two representations or the single fields. This result pertains to both structured and unstructured query mode in best match retrieval, however, with the latter query mode demonstrating higher performance. The retrieval overlaps containing search keys from the bibliographic references provide the best retrieval performance and minor MeSH terms the worst. It is concluded that a highly structured query language is necessary when implementing the principle of polyrepresentation in a best match IR system because the principle is inherently Boolean. Finally a re-ranking test shows promising results when search results are re-ranked according to precision obtained in the overlaps whilst re-ranking by citations seems less useful when integrated into polyrepresentative applications.  相似文献   

Shadow ILL Services: How Scholarly Pirate Websites and Hacking Affect ILL     

Kaitlin Kehnemuyi  Sylvie C. Larsen 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2019,28(5):139-149

Abstract

Full-text research pirating sites are a fact of life at this point. Regardless of how we personally feel about this issue, the fact that students, researchers, and patrons are turning away from the library as a legitimate source for research documents means libraries’ numbers are affected. We are all seeing usage numbers go down, it’s a trend throughout ILL. This could be for a number of reasons: use of OA and pre-print servers, better collection development, or an increase in use of pirating or black market PDF websites. Regardless, this decrease in numbers can lead to a decrease in funding for our departments. At the same time we have seen cases of abuse in institutional logins. During this discussion we will look at some examples of attempted phishing and impersonation techniques used by “pirates,” our library patrons’ motivations for using these sites, consequences for the user as well as the institution, and the role of ILL in this conundrum.  相似文献   

Risk and protective factors for mental health in elite athletes: a scoping review     

A. Kuettel  C. H. Larsen 《International review of sport and exercise psychology》2020,13(1):231-265

ABSTRACT

The purpose of this scoping review was to provide an overview of studies concerning the mental health (MH) of elite athletes and to provide a methodological, conceptual, and applied overview of factors affecting elite athletes’ MH. A total of nine reviews and 43 empirical studies were evaluated and are reported in three sections: sample characteristics, research design, and factors affecting elite athletes’ MH. These factors were grouped into risk and protective factors and divided into a personal and sport-environmental domain. The studies used quantitative (84%), qualitative (11%), and mixed-method (5%) designs and examined a wide range of sports in different countries. Our review shows that researchers have predominantly examined the prevalence of athletes’ mental ill-health (e.g. depression) and the related factors compromising MH. Potential protective factors such as the feeling of autonomy, positive relations in sport and private life, and adequate recovery were highlighted in the qualitative studies. The discussion appraises the findings through a critical lens, focuses on the current state of the research area and the MH definition, limitations, suggested practical implications (e.g. to provide MH literacy to both athletes and coaches), and future research directions (e.g. examining environments that foster elite athletes’ MH).  相似文献

Protection or Participation?     

Anna Grøndahl Larsen 《Journalism Practice》2017,11(7):893-908

Children’s status as a particularly vulnerable group in society implies a journalistic obligation to shed light on children’s stories and listen to their perspectives, but their vulnerable position also means they deserve protection from potentially harmful news coverage. Based on a close-reading of two extensively covered news serials concerning irregular migrant children facing deportation, and on in-depth interviews with journalists, editors, and key actors working on behalf of irregular migrant children, the present article sheds light on how journalists balance competing, ethical, professional, and organizational concerns when reporting on issues concerning children. The article shows that while journalists say they are aware of the ethical aspects concerning extensive media exposure of young children, they justify the reporting by foregrounding children as innocent victims of the immigration system and by highlighting the journalistic obligation of shedding light on the wrongdoings of this system. The potential burden of media exposure is relativized as less harmful than the alternative—deportation. Theoretically, the article contributes to the literature on children in the news media, human-interest stories and journalism, and the role of journalism reporting vulnerable groups.  相似文献   

Degradation of collagen in parchment under the influence of heat-induced oxidation: Preliminary study of changes at macroscopic,microscopic, and molecular levels     

Kathleen Mühlen Axelsson  René Larsen  Dorte V.P. Sommer  Rikke Melin 《文物保护研究》2016,61(1):46-57

This paper examines the impact of heat-induced oxidation for new and historical parchment with the purpose of improving diagnostic tools for use in practical parchment conservation. Oxidation was generated by heat aging at 120°C in a dry oven for 24, 48, and 96 hours, respectively. The degradation was assessed on all samples at macrolevel by measuring color changes, at microlevel by measuring the shrinkage temperature as well as by performing a visual assessment of the fibers’ morphology and determining the amount of damaged fibers, and finally, at molecular level where amino acid analysis was used to reveal changes in the oxidized collagen. The study shows that the heat-induced oxidation leads to significant color changes, decrease in hydrothermal stability, as well as changes in the amino acid composition. Surprisingly, the results show that the historical parchment is more sensitive towards dry heat oxidation on a molecular level than is the new parchment. Furthermore, for the first time, we can show that physical damage reflected in the morphological characteristics of fibers can be attributed to oxidation by dry heat.  相似文献
