Technology,Gender and Time: A Contribution to the Debate

Using the data collected from research carried out at two Portuguese universities, this article highlights the way university lecturers currently deal with space and time. Their professional activity is not externally subjected to a specific time geometry that defines their working day. Teaching and researching time–spaces are basically task oriented. Furthermore, university lecturers are increasingly requested to perform tasks in very short time periods in order to secure financial support. To a certain extent, this pressure upon their work is facilitated by the use of technology. However, technology also causes a profound reconfiguration of working times and spaces, especially because it allows lecturers to work at any time from anywhere. This not only renders university physical spaces and times virtual, but it also leads to the colonization of several other time–spaces of their social lives. This article analyses the ambivalence and difficulty of managing time–spaces, as described by the lecturers themselves, with the objective of providing a more accurate awareness of the implications of technology on their lives, as well as the hazards of the progressive externalization of academic work, particularly for women.     

A generalization of Jeffreys' rule for non regular models

ABSTRACT

We propose a generalization of the one-dimensional Jeffreys' rule in order to obtain non informative prior distributions for non regular models, taking into account the comments made by Jeffreys in his article of 1946. These non informatives are parameterization invariant and the Bayesian intervals have good behavior in frequentist inference. In some important cases, we can generate non informative distributions for multi-parameter models with non regular parameters. In non regular models, the Bayesian method offers a satisfactory solution to the inference problem and also avoids the problem that the maximum likelihood estimator has with these models. Finally, we obtain non informative distributions in job-search and deterministic frontier production homogenous models.     

The sample monomode and an associated test for discrete monomodality

Abstract

The notions of (sample) mean, median and mode are common tools for describing the central tendency of a given probability distribution. In this article, we propose a new measure of central tendency, the sample monomode, which is related to the notion of sample mode. We also illustrate the computation of the sample monomode and propose a statistical test for discrete monomodality based on the likelihood ratio statistic.     

A Comparison of Bayes Factors for Separated Models: Some Simulation Results

Some alternative Bayes Factors: Intrinsic, Posterior, and Fractional have been proposed to overcome the difficulties presented when prior information is weak and improper prior are used. Additional difficulties also appear when the models are separated or non nested. This article presents both simulation results and some illustrative examples analysis comparing these alternative Bayes factors to discriminate among the Lognormal, the Weibull, the Gamma, and the Exponential distributions. Simulation results are obtained for different sample sizes generated from the distributions. Results from simulations indicates that these alternative Bayes factors are useful for comparing non nested models. The simulations also show some similar behavior and that when both models are true they choose the simplest model. Some illustrative example are also presented.     

On the recoding of continuous and bounded indexes to a binomial form: an application to quality-of-life scores

The statistical analysis of patient-reported outcomes (PROs) as endpoints has shown to be of great practical relevance. The resulting scores or indexes from the questionnaires used to measure PROs could be treated as continuous or ordinal. The goal of this study is to propose and evaluate a recoding process of the scores, so that they can be treated as binomial outcomes and, therefore, analyzed using logistic regression with random effects. The general methodology of recoding is based on the observable values of the scores. In order to obtain an optimal recoding, the evaluation of the recoding method is tested for different values of the parameters of the binomial distribution and different probability distributions of the random effects. We illustrate, evaluate and validate the proposed method of recoding with the Short Form-36 (SF-36) Survey and real data. The optimal recoding approach is very useful and flexible. Moreover, it has a natural interpretation, not only for ordinal scores, but also for questionnaires with many dimensions and different profiles, where a common method of analysis is desired, such as the SF-36.     

Dirty money? The politics of representation in Cuban revolutionary banknotes

This article examines the visual politics of Cuban postrevolutionary banknotes, focusing on the series minted in 1961. It is argued that the iconography of this series – which stresses the revolutionary merits of Fidel Castro and his movement, and associates the latter with the independence wars – portrays the Castro-led Cuban Revolution as the fulfilment of the nation’s aspiration to sovereignty. The article maintains that the design of the 1961 banknote series articulates tropes that convey a fidelista imaginary, presenting the visual rhetoric of currencies as a mechanism of propaganda and persuasion.     

International Adaptation of a Treatment Program for Situational Couple Violence

Intimate Partner Violence (IPV) is a serious international problem. Stith, S. M., McCollum, E. E., and Rosen, K. H. received funding from the US National Institute of Mental Health to develop and test a program for couples experiencing IPV: Domestic Violence Focused Couples Treatment (DVFCT). This article provides an overview of DVFCT, and presents three case studies illustrating how DVFCT has been adapted for use in Colombia, Iran, and Finland. This article emphasizes the need for adapting treatment models to be culturally informed, provides practice-based evidence for DVFCT as a treatment model, and highlights the importance of careful screening and assessment when working with couples who have experienced violence, no matter the country or location where treatment is being conducted.     

OECD: One or Many? Ranking Countries with a Composite Well-Being Indicator

In the social sciences it is hardly contested that “institutions matter”. Consequently the analysis of differences and similarities of institutions should be a routine task. Prevailing methods to the measurement of institutions are however problematic, in particular when they have to deal with different levels of measurement. To overcome this, in this paper we present an innovative method to the quantification of qualitative institutional data. We do this by, first, developing benchmarks for comparison based on Weberian ideal types. Then we identify and operationalise the dimensions and indicators to a nuanced measurement of institutions, after which we apply a careful and differentiated scoring, weighting and aggregation procedure in order to guarantee the highest standards of comparability, transparency and reliability of the method. Finally, we demonstrate our method by applying it to the analysis of institutional individualisation in European welfare institutions.     

Social Differences in the Decline of Marital Reproduction in Rural Navarre (Spain)

The continued decline of marital fertility in Navarre (Spain) during the first few decades of the twentieth century was associated with an increase in life expectancy and greater survival to adulthood. This decline affected all social strata and all geographical regions, rural areas as well as cities. Nonetheless, the decline was not homogeneous. Some sectors of Navarrese society began the fertility transition earlier than others.Cross sectional analysis is presented for different years of diverse variables that could be related to the levels of marital fertility: level of urbanization, occupation of the father, level of religious devotion and political factors. Statistical evidence is presented that confirms the relationship of these variables to the levels of fertility.
