Are older adults satisfied with their sexuality? Outcomes from a cross-cultural study

ABSTRACT

The present study intends to analyze older adult perspectives on what determines sexual satisfaction in old age. Four hundred and twenty-one non-institutionalized older parti- 10 cipants from three different nationalities aged 65 to 97 years were interviewed. All narratives were submitted to content analysis. This study’s outcome originated five themes: positive communication (k =.94, p <.01); supportive partner (k =.82, p <.01); feeling attractive (k = 81, p <.01); good sexual activity (k =.97, p <.01); and eroticism (k =.98, p <.01). 15 This study highlighted different determinants of sexual satisfaction in old age and emphasized the importance of positive communication and a supportive partner for older adults.     

Education as habitus transformations

Unlike a conventional reading of Bourdieu, this article focuses on his work with regard to the transformation of social structure. In the context of a rereading, from an educational theory perspective, the article proposes an approach that allows for the linking of empirically informed social theory, on the one hand, and biography research oriented to educational theory, on the other. Education, here, is generally conceived of as habitus transformation. For reconstructing the societal conditions of the possibility of education one needs to go beyond the habitus theory and its focus on actors and groups of actors. From the perspective of a theory of practice as proposed by Bourdieu, the concept that comes to mind is that of social field, largely neglected in the theory-of-education discourse. Based on a combination of biography analysis and discourse analysis is, then, presented as a perspective for a relational theory of education. The article aims to outline an empirical reconstruction of transformation processes between habitus and field.     

Teaching Teamwork: Electronics Instruction in a Collaborative Environment

ABSTRACT

The Teaching Teamwork Project is using an online simulated electronic circuit, running on multiple computers, to assess students’ abilities to work together as a team. We pose problems that must be tackled collaboratively, and log students’ actions as they attempt to solve them. Team members are isolated from one another and can communicate only through an online chat channel, but modifications to the circuit made by any team member, insofar as they alter the behavior of the circuit, can affect measurements made by the others. We log all relevant student actions, including calculations (using an online calculator), measurements (using an online multimeter), inter-student communications, and alterations made by the students to the circuit itself. Automated analysis of the resulting data sheds light on the problem-solving strategy of each team, sometimes with surprising results.     

International networking for sexuality education: a politically sensitive subject

In 2007, six countries (Argentina, Brazil, Chile, Paraguay, Peru and Uruguay) commenced work on a project to harmonise public policy on school sexuality education (SE) and the prevention of HIV. Inter-sectoral management committees for SE involving ministries of education, ministries of health and civil society were established, national policies and work plans were formulated and implemented, and SE/HIV prevention activities were carried out. The strengths and weaknesses of implementation were assessed. After this, the beginnings of a community of practice were created, with national focal points. This paper analyses the above process using qualitative data generated through semi-structured questionnaires and interviews, with a focus on the perceived contribution of regional collaboration to the development of national policies, national curricula and implementation. Overall, the initiative reached 83,000 teachers and 1,500,000 pupils. Training materials and national curricula and policies were developed, introduced and implemented. Regional collaboration improved political institutionalisation, information exchange, inter-sectoral collaboration, civil society participation, programme legitimacy and the perception of SE as a young person's right. The initiative offers a model for other countries, with regional collaboration helping to establish the case for SE both normatively and institutionally at the political level, mitigate obstacles in the context of such a politically sensitive topic as SE and provide a forum for discussion and the exchange of information which in turn helped legitimise and operationalise national SE policies.     

PubMed Instruction for Medical Students: Searching for a Better Way

In 2007, Duke University Medical Center Library instituted an interactive, online PubMed tutorial and quiz for medical students to replace an in-person lecture. This article describes the events leading to this educational paradigm shift and how the tutorial was implemented. Important concerns in the switch to an online approach to PubMed training were student satisfaction and the extent to which searching skills would improve. To determine the effectiveness of the online model, two years of student quizzes and evaluations were examined. Results indicate that students benefit from and appreciate the interactive tutorial.     

A Unified Latent Growth Curve Model

Applying item response theory models to repeated observations has demonstrated great promise in developmental research. By allowing the researcher to take account of the characteristics of both item response and measurement error in longitudinal trajectory analysis, it improves the reliability and validity of latent growth curve analysis. This has enabled the study, to differentially weigh individual items and examine developmental stability and change over time, to propose a comprehensive modeling framework, combining a measurement model with a structural model. Despite a large number of components requiring attention, this study focuses on model formulation, evaluates the performance of the estimators of model parameters, incorporates prior knowledge from Bayesian analysis, and applies the model using an illustrative example. It is hoped that this fundamental study can demonstrate the breadth of this unified latent growth curve model.     

It’s not the economy, stupid! External effects on the supply and demand of cinema entertainment

The paper addresses whether the state of the economy impacts the supply of and demand for cinema entertainment. A literature review on the drivers of cinema supply and demand is provided, and two competing hypotheses are extracted. Economic downturns could either lead to a sober mood and drive the interest in serious genres or drive the need for distraction leading to an increased interest in feel-good or action movies. However, characteristics of the movie industry suggest that economic key factors have only limited effects on supply and demand. A time series analysis of supply and demand in three major European markets indicate that demand is unrelated to the state of the economy. In aggregate, the demand does not instruct supply. Fluctuations in individual movie quality superpose potential effects of the economic context on the aggregated demand. Simultaneously, a focus on film as art superposes potential effects of the economic context on the supply.     

International patent disputes: Evidence from oppositions at the European Patent Office

The impact of the geographical origin of patents on the probability of an opposition being filed and a patent being revoked has been examined in this paper, after accounting for patent value indicators and industry specificities. The study is based on a dataset of approximately 450,000 EPO granted patents and 24,000 patent opposition cases in the years 2000–2008. We find that patents with a first priority in the US are less likely to be challenged, although they are relatively more likely to be revoked than patents with a priority in a member country of the European Patent Convention. Patents from Japan have less probability of being opposed and are less likely to be revoked than the other countries. A disaggregation of the European countries has revealed that patents with a German priority have a higher or similar likelihood of being opposed than patents from the other countries, with the exceptions of The Netherlands and Denmark.     

Spike jump biomechanics in male versus female elite volleyball players

ABSTRACT

There are well-known biological differences between women and men, especially in technical-coordinative variations that contribute to sex differences in performance of complex movements like the most important offensive action in volleyball, the spike jump. The aim of this study was to investigate sex-dependent performance and biomechanical characteristics in the volleyball spike jump. Thirty female and male sub-elite volleyball players were analysed while striking a stationary ball with maximal spike jump height. Twelve MX13 Vicon cameras with a cluster marker set, two AMTI force plates, surface EMG, and a Full-Body 3D model in Visual3D were used. Main findings include sex differences (P< .05) in jump height (pη² = .73), approach [speed (pη² = .61), step length], transition strategy [plant angle, neuromuscular activation (pη² = .91), horizontal force maxima and impulses], acceleration distances [centre of mass displacement (pη² = .21), minimal knee and hip angles], use of torso and arms [incline, angular velocity (pη² = .23)]. Correlations support that the results cannot be explained fully by strength and power differences between sexes but represent the product of technical-coordinative variations. Their relevance is acknowledged for both sexes and numerous performance determinants displayed sex differences. The integration of such attributes into sex-specific training seems promising but its effect requires further investigation.     

Local Equating Using the Rasch Model,the OPLM,and the 2PL IRT Model—or—What Is It Anyway if the Model Captures Everything There Is to Know About the Test Takers?

Local equating (LE) is based on Lord's criterion of equity. It defines a family of true transformations that aim at the ideal of equitable equating. van der Linden (this issue) offers a detailed discussion of common issues in observed‐score equating relative to this local approach. By assuming an underlying item response theory model, one of the main features of LE is that it adjusts the equated raw scores using conditional distributions of raw scores given an estimate of the ability of interest. In this article, we argue that this feature disappears when using a Rasch model for the estimation of the true transformation, while the one‐parameter logistic model and the two‐parameter logistic model do provide a local adjustment of the equated score.
