Gendered Career Pathways among Doctoral Graduates in the United Kingdom

This is the final version. Available on open access from MDPI via the DOI in this recordWhile women form about half of PhD students in Western countries, previous studies have shown that female doctoral graduates are underrepresented in senior positions and have lower earnings compared to their male counterparts within and outside academia. Less is known however about the role of gender in determining the odds of securing a permanent position among doctorate recipients. In this study, we use data from the UK Doctoral Impact and Career Tracking Survey from 2013 to explore the career trajectories of doctoral graduates within seven to nine years after earning their degree. We find that in every observed time point following graduation (0.5, 3.5, and 7–9 years), men are significantly more likely to work in a permanent job than women are. Furthermore, gender gaps in permanent employment are particularly pronounced in the private sector and in non-academic occupations. Using a nested logistic regression model, we find that the higher propensity of female doctoral graduates to work in part-time employment compared to their male counterparts, in combination with other differential employment characteristics has cumulative negative implications on their likelihood of securing a permanent position

The SkipTrie: low-depth concurrent search without rebalancing

To date, all concurrent search structures that can support predecessor queries have had depth logarithmic in m, the number of elements. This paper introduces the SkipTrie, a new concurrent search structure supporting predecessor queries in amortized expected O(log log u + c) steps, insertions and deletions in O(c log log u), and using O(m) space, where u is the size of the key space and c is the contention during the recent past. The SkipTrie is a probabilistically-balanced version of a y-fast trie consisting of a very shallow skiplist from which randomly chosen elements are inserted into a hash-table based x-fast trie. By inserting keys into the x-fast-trie probabilistically, we eliminate the need for rebalancing, and can provide a lock-free linearizable implementation. To the best of our knowledge, our proof of the amortized expected performance of the SkipTrie is the first such proof for a tree-based data structure.National Science Foundation (U.S.) (Grant CCF-1217921)United States.

Fertility differences by education in Britain and France: The role of religion

This is the final version. Available from I.N.E.D via the link in this recordFemale education is generally associated with lower fertility and higher rates of childlessness. However, it remains unclear whether higher education implies similar fertility behaviour among women of different religious denominations at varying levels of religiosity. To assess whether this is the case, this study uses data from the British Household Panel Survey and the French Generations and Gender Survey to explore the intersection of religion (measured by religious practice, Catholic affiliation in France, and Protestantism and in Britain), education, and fertility outcomes for women born between the 1920s and 1960s. In Britain, higher education reduces the odds of entering motherhood more often among religiously unaffiliated women compared to nominally and practising religious women, although no such interaction effect is found in France. However, religiosity in both countries attenuates the negative relationship between education and completed family size. While unaffiliated women have a negative educational gradient of fertility, this study finds a U-shaped relationship between education and completed fertility among practising Catholic women. Moreover, differences in completed fertility by religious affiliation and practice are more pronounced among highly educated women. These findings are attributed to differences in the perceived value and costs of children across religious groups

Differences in partnership and marital status at first birth by women’s and partners’ education: Evidence from Britain 1991-2012

Non-marital childbearing, especially within cohabitation, has become increasingly common in Britain as in other Western countries. Nonetheless, births outside marriage occur more frequently among the relatively disadvantaged in terms of income potential. Building upon previous research in family formation patterns, we examine differences by education and employment status in the proportion of marital and non-marital first births among British women and couples over the past two decades. In particular, we explore trends in educational differences in non-marital first births among women and the role of partners’ joint educational attainment in relation to childbearing within cohabitation or within marriage. We find a steady increase in cohabiting first births among all educational groups, without significant change in unpartnered births. However, differences by education in non-marital first births have not increased significantly during the observed period. Male partner’s education is negatively associated with childbearing within cohabitation, although this relationship varies according to women’s educational attainment.This work was supported by the Philomathia Social Sciences Research Programme, University of Cambridge

Addressing the human resources crisis: A case study of Cambodia's efforts to reduce maternal mortality (1980-2012)

Objective: To identify factors that have contributed to the systematic development of the Cambodian human resources for health (HRH) system with a focus on midwifery services in response to high maternal mortality in fragile resource-constrained countries. Design: Qualitative case study. Review of the published and grey literature and in-depth interviews with key informants and stakeholders using an HRH system conceptual framework developed by the authors ('House Model'; Fujita et al, 2011). Interviews focused on the perceptions of respondents regarding their contributions to strengthening midwifery services and the other external influences which may have influenced the HRH system and reduction in the maternal mortality ratio (MMR). Setting: Three rounds of interviews were conducted with senior and mid-level managers of the Ministries of Health (MoH) and Education, educational institutes and development partners. Participants: A total of 49 interviewees, who were identified through a snowball sampling technique. Main outcome measures: Scaling up the availability of 24 h maternal health services at all health centres contributing to MMR reduction. Results: The incremental development of the Cambodian HRH system since 2005 focused on the production, deployment and retention of midwives in rural areas as part of a systematic strategy to reduce maternal mortality. The improved availability and access to midwifery services contributed to significant MMR reduction. Other contributing factors included improved mechanisms for decision-making and implementation; political commitment backed up with necessary resources; leadership from the top along with a growing capacity of mid-level managers; increased MoH capacity to plan and coordinate; and supportive development partners in the context of a conducive external environment. Conclusions: Lessons from this case study point to the importance of a systemic and comprehensive approach to health and HRH system strengthening and of ongoing capacity enhancement and leadership development to ensure effective planning, implementation and monitoring of HRH policies and strategies.sch_iih3pub3197pub

Not Just Efficiency: Insolvency Law in the EU and Its Political Dimension

Certain insolvency law rules, like creditors’ priorities and set-off rights, have a distributive impact on creditors. Distributional rules reflect the hierarchies of values and interests in each jurisdiction and, as a result, have high political relevance and pose an obstacle to reforming the EU Insolvency Regulation. This paper will show the difficulty of reform by addressing two alternative options to regulate cross-border insolvencies in the European Union. The first one is the ‘choice model’, under which companies can select the insolvency law they prefer. Although such a model would allow distressed firms to select the most efficient insolvency law, it would also displace Member States’ power to protect local constituencies. The choice model therefore produces negative externalities and raises legitimacy concerns. The opposite solution is full harmonisation of insolvency law at EU level, including distributional rules. Full harmonisation would have the advantage of internalising all externalities produced by cross-border insolvencies. However, the EU legislative process, which is still based on negotiations between states, is not apt to decide on distributive insolvency rules; additionally, if harmonisation includes such rules, it will indirectly modify national social security strategies and equilibria. This debate shows that the choice regarding power allocation over bankruptcies in the EU depends on the progress of European integration and is mainly a matter of political legitimacy, not only of efficiency

Towards energy aware cloud computing application construction

The energy consumption of cloud computing continues to be an area of significant concern as data center growth continues to increase. This paper reports on an energy efficient interoperable cloud architecture realised as a cloud toolbox that focuses on reducing the energy consumption of cloud applications holistically across all deployment models. The architecture supports energy efficiency at service construction, deployment and operation. We discuss our practical experience during implementation of an architectural component, the Virtual Machine Image Constructor (VMIC), required to facilitate construction of energy aware cloud applications. We carry out a performance evaluation of the component on a cloud testbed. The results show the performance of Virtual Machine construction, primarily limited by available I/O, to be adequate for agile, energy aware software development. We conclude that the implementation of the VMIC is feasible, incurs minimal performance overhead comparatively to the time taken by other aspects of the cloud application construction life-cycle, and make recommendations on enhancing its performance

Variability in the analysis of a single neuroimaging dataset by many teams

Data analysis workflows in many scientific domains have become increasingly complex and flexible. To assess the impact of this flexibility on functional magnetic resonance imaging (fMRI) results, the same dataset was independently analyzed by 70 teams, testing nine ex-ante hypotheses1. The flexibility of analytic approaches is exemplified by the fact that no two teams chose identical workflows to analyze the data. This flexibility resulted in sizeable variation in hypothesis test results, even for teams whose statistical maps were highly correlated at intermediate stages of their analysis pipeline. Variation in reported results was related to several aspects of analysis methodology. Importantly, a meta-analytic approach that aggregated information across teams yielded significant consensus in activated regions across teams. Furthermore, prediction markets of researchers in the field revealed an overestimation of the likelihood of significant findings, even by researchers with direct knowledge of the dataset2-5. Our findings show that analytic flexibility can have substantial effects on scientific conclusions, and demonstrate factors possibly related to variability in fMRI. The results emphasize the importance of validating and sharing complex analysis workflows, and demonstrate the need for multiple analyses of the same data. Potential approaches to mitigate issues related to analytical variability are discussed

Do Neuro-Muscular Adaptations Occur in Endurance-Trained Boys and Men?

Most research on the effects of endurance training has focused on endurance training's health-related benefits and metabolic effects in both children and adults. The purpose of this study was to examine the neuromuscular effects of endurance training and to investigate whether they differ in children (9.0-12.9 years) and adults (18.4-35.6 years). Maximal isometric torque, rate of torque development (RTD), rate of muscle activation (Q30), electromechanical delay (EMD), and time to peak torque and peak RTD were determined by isokinetic dynamometry and surface electromyography (EMG) in elbow and knee flexion and extension. The subjects were 12 endurance-trained and 16 untrained boys, and 15 endurance-trained and 20 untrained men. The adults displayed consistently higher peak torque, RTD, and Q30, in both absolute and normalized values, whereas the boys had longer EMD (64.7+/-17.1 vs. 56.6+/-15.4 ms) and time to peak RTD (98.5+/-32.1 vs. 80.4+/-15.0 ms for boys and men, respectively). Q30, normalized for peak EMG amplitude, was the only observed training effect (1.95+/-1.16 vs. 1.10+/-0.67 ms for trained and untrained men, respectively). This effect could not be shown in the boys. The findings show normalized muscle strength and rate of activation to be lower in children compared with adults, regardless of training status. Because the observed higher Q30 values were not matched by corresponding higher performance measures in the trained men, the functional and discriminatory significance of Q30 remains unclear. Endurance training does not appear to affect muscle strength or rate of force development in either men or boys
