Data for 'Divergent allocation of sperm and the seminal proteome along a competition gradient in Drosophila melanogaster'
No full textThese four datasets were collected and analysed as part of the paper 'Divergent allocation of sperm and the seminal proteome along a competition gradient in Drosophila melanogaster'. The datasets give: sperm count data; the 5-mating experiment data; accessory gland replenishment data; and single mating experiment data
Temporary employment, job satisfaction and subjective well-being
No full textThis article is concerned with whether employees on temporary contracts in Britain report lower well-being than those on permanent contracts, and whether this relationship is mediated by differences in dimensions of job satisfaction. Previous research has identified a well-being gap between permanent and temporary employees but has not addressed what individual and contract specific characteristics contribute to this observed difference. Using data from the British Household Panel Survey, the article finds that a large proportion of the difference in self-reported well-being between permanent and temporary employees appears to be explained by differences in satisfaction with job security. Other dimensions of job satisfaction are found to be less important. In fact, after controlling for differences in satisfaction with security, the results suggest that temporary employees report higher psychological well-being and life satisfaction. This indicates that an employment contract characterized by a definite duration lowers individual well-being principally through heightened job insecurit
Understanding the Perception of the ‘Migrant Work Ethic’
Full text linkOver the last decade, the UK has experienced unprecedented increases in migration associated with the 2004 A8 expansion of the European Union. These migrant workers have been praised by managers in the UK, who have frequently stated that they perceive these workers to have a strong ‘work ethic’ when measured on aspects such as absence from work rates. This article examines this perceived migrant ‘work ethic’ by analysing worker absence data from the UK Quarterly Labour Force Survey for the period 2005–2012. Regression analysis reveals that when A8 migrant workers first arrive in the UK, they record substantially lower absence than native workers, but that these migrant absence levels assimilate within two to four years. If employers use this information to make hiring decisions, this may have negative implications for native workers, but, importantly, only in the short run
Absence management of migrant agency workers in the food manufacturing sector
Full text linkTemporary workers in low-skilled roles often experience ‘hard’ HRM practices, for example the use of the Bradford Factor to monitor absence, rather than using incentives to reward attendance. However, this peripheral workforce has become increasingly diverse in the UK since the A8 European Union expansion, which has seen over a million migrants from central and eastern Europe register to work in the UK. Importantly, there is also heterogeneity within this group of workers, for example between those who intend to migrate for a short period of time then return, and those who are more settled and wish to develop a career. By considering the particular case of absence management, this paper examines how these different groups of migrants respond to HRM practices. The key contribution of the paper is to examine how different groups of migrants experience these practices, rather than simply comparing migrant and native workers as two homogeneous groups. The paper presents data from the food manufacturing sector in the UK. In total, 88 semi-structured interviews were conducted with operations managers, HR managers, union convenors and workers on permanent, temporary and agency contracts. In addition, data from informal interviews and observation at five companies are presente
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
