Gender discourses in academic mobility

Despite increasing geographic mobility among academic staff, gendered patterns of involvement in academic mobility have largely escaped scrutiny. Positioned within literatures on internationalization, physical proximity, gender and parenthood in academic mobility and understandings of gender as a process enacted through both discursive and embodied practices, we use discourse analysis based on interviews with academics in New Zealand to examine differences in language that create differing realities with regards to gender and obligations of care in academic mobility decisions. The findings reveal how academic mobility is discursively formulated as ‘essential’ to successful academic careers, with the need for frequent travel justified despite advances in virtual communication technologies. Heteronormative discourses are shown to disrupt and fragment the opportunities female academics have to engage in academic mobility. However, we also uncover ways in which these discourses are resisted, wherein fathers articulate emotional strain associated with academic mobility. The article shows how discourse works to constitute the essentialization of academic mobility, and the uneven gendered practices associated with it, whilst also giving voice to gender inequities in academic mobility from the southern hemisphere.

Estimation in the singly truncated weibull distribution with an unknown truncation point

When truncation points are unknown, they must be treated as additional parameters to be estimated from the sample data. In this article, estimators are derived for the truncation parameter in addition to basic parameters of both 1eft and riqht sing1y truncated Weibull distributions, Maximum likelihood estimators and estimators involving expected values of appropriate order statistics are derived, Asymptotic sampling errors of estimates are also given, Ill ustrative examples are inc1uded.     

Population forecasts and confidence intervals for sweden: a comparison of model-based and empirical approaches

This paper compares several methods of generating confidence intervals for forecasts of population size. Two rest on a demographic model for age-structured populations with stochastic fluctuations in vital rates. Two rest on empirical analyses of past forecasts of population sizes of Sweden at five-year intervals from 1780 to 1980 inclusive. Confidence intervals produced by the different methods vary substantially. The relative sizes differ in the various historical periods. The narrowest intervals offer a lower bound on uncertainty about the future. Procedures for estimating a range of confidence intervals are tentatively recommended. A major lesson is that finitely many observations of the past and incomplete theoretical understanding of the present and future can justify at best a range of confidence intervals for population projections. Uncertainty attaches not only to the point forecasts of future population, but also to the estimates of those forecasts' uncertainty.     

Recession and Divorce in the United States, 2008–2011

Recession may increase divorce through a stress mechanism, or reduce divorce by exacerbating cost barriers or strengthening family bonds. After establishing an individual-level model predicting US women’s divorce, the paper tests period effects, and whether unemployment and foreclosures are associated with the odds of divorce using the 2008–2011 American Community Survey. Results show a downward spike in the divorce rate after 2008, almost recovering to the expected level by 2011, which suggests a negative recession effect. On the other hand, state foreclosure rates are positively associated with the odds of divorce with individual controls, although this effect is not significant when state fixed effects are introduced. State unemployment rates show no effect on odds of divorce. Future research will have to determine why national divorce odds fell during the recession, while state-level economic indicators were not strongly associated with divorce. Exploratory analysis which shows unemployment decreasing divorce odds for those with college degrees, while foreclosures have the opposite effect, provide one possible avenue for such research.
