Validation of the OMNI-cycle scale of perceived exertion in the elderly

This study examined the concurrent and construct validity of the OMNI-Cycle Rating of Perceived Exertion (RPE) Scale, using elderly men and women. Seventy-six participants performed a load-incremented cycle-ergometer exercise test. Concurrent validity was determined by correlating OMNI-RPE responses with oxygen uptake, relative peak oxygen uptake, pulmonary ventilation, heart rate, respiratory rate, and respiratory-exchange ratio during a load-incremented cycle-ergometer protocol. Construct validity was established by correlating RPE derived from the OMNI-Cycle Scale with RPE from the Borg (6-20) Scale. Multilevel, mixed linear-regression models indicated that OMNI-RPE distributed as a significant (p < .05) positive linear function (r = .81-.92) for all physiological measures. OMNI-RPE was positively (p < .01) and linearly related to Borg-RPE in elderly men (r = .97) and women (r = .96). This study demonstrates both concurrent and construct validity of the OMNI-Cycle RPE Scale. These findings support the use of this scaling metric with elderly men and women to estimate RPE during cycle-ergometer exercise.     

Home sweet home: The emotional construction of places

The social sciences have recently shown a revival of interest in space and place. In this “spatial turn” the place is seen as a “place-in-process” (Thrift, 2008) and as the emergent result of constant re-involvement processes based on the continuous re-definition and re-construction of its meaning. Moreover, elderly people's homes have acquired a renewed importance in the wake of an aging in place strategy in social and health policies. This study describes the processes of situatedness of place that occur during the widowhood. Involving ten older widows, our analysis identifies four distinct processes in the construction of the situated meaning of a place: ‘Heart displacement’, ‘The showcase of the self’, ‘Refuge’ and ‘Introjection of external spaces’.     

Multilateralism under threat: Causes,impact, and the policy debate on government intervention in trade

Several forces fostered trade liberalization since the end of World War II. Production and trade interacted quite favorably during the period. In the past quarter century real income in the OECD economies grew at almost 4% yearly, while the volume of export increased by almost 7 percent. However, in the first half of the 1980s, the chemistry of the situation seems to have changed as protectionist tendencies developed almost everywhere in the world. The very same multilateral nature of the world trading system is under threat, as illiberal discriminatory practices are being implemented bilaterally and, even more often, unilaterally. What are the forces at play to increase the pressure towards government intervention in trade? The paper reviews (i) macroeconomic issues and policy situations, as well as (ii) structural issues concerning the working of the economic systems of industrial countries. The pressure for trade intervention in the U.S. is addressed separately with respect to Europe, given the structural and cyclical differences between the two economies The case of Japan is dealt with with reference to the alleged interrelation between Japan's international competitiveness and its macroeconomic policies. Matters of more direct concern to the LDCs are covered at the end of the paper, with emphasis placed on the restructuring process under way in response to, and as a consequence of, the external debt. The paper ends with a recommendation to all countries to make efforts to preserve and strengthen the multilateral and liberal foundations of the international trading system.     

Postmodern society and the individual: The structural characteristics of postmodern society and how they shape who we think we are

The notion that personality is pluralistic and not a rigid construct is widely acknowledged within the social sciences. However, factors affecting multiplicity outside of clinical enquiry are still poorly understood. The idea that postmodern society has influenced how the individual conceives of their self-concept is frequently discussed, however, seldom theorized and empirically inspected. This study tests a number of psycho-sociological hypotheses that being immersed within consumption and part of a technology-based culture are contributing factors to self-pluralism. Data is collected from 201 individuals living in postmodern societies. Results indicate that technology exposure and materialistic beliefs are related to levels of self-pluralism and that materialism plays a partial mediatory role in technology's influence on multiplicity. These findings add support to postmodern understandings of the self and society and show everyday experiences associated with modern living influence how one conceives of their identity.     

Bayesian Kernel Mixtures for Counts

Although Bayesian nonparametric mixture models for continuous data are well developed, there is a limited literature on related approaches for count data. A common strategy is to use a mixture of Poissons, which unfortunately is quite restrictive in not accounting for distributions having variance less than the mean. Other approaches include mixing multinomials, which requires finite support, and using a Dirichlet process prior with a Poisson base measure, which does not allow smooth deviations from the Poisson. As a broad class of alternative models, we propose to use nonparametric mixtures of rounded continuous kernels. An efficient Gibbs sampler is developed for posterior computation, and a simulation study is performed to assess performance. Focusing on the rounded Gaussian case, we generalize the modeling framework to account for multivariate count data, joint modeling with continuous and categorical variables, and other complications. The methods are illustrated through applications to a developmental toxicity study and marketing data. This article has supplementary material online.     

Resolving Coparenting Dissatisfaction In Couples: A Preliminary Task Analysis Study

This study explored the change that unfolded when parents resolved their coparenting dissatisfaction during an Integrative Brief Systemic Intervention (IBSI) for parent couples. We conducted a task analysis (Greenberg, 2007) to build a model of resolving coparenting dissatisfaction. We compared a postulated model of change (rational model) based on theoretical and clinical assumptions to the observations of the actual change process that couples experienced in an IBSI (empirical analysis). The empirical analysis was conducted on six IBSI therapy cases (three exhibiting positive development and three exhibiting no development). We defined positive development in IBSI as moving from coparenting dissatisfaction to coparenting satisfaction. The final rational–empirical model included six steps that facilitated the resolution of coparenting dissatisfaction. This study contributes to deepening the knowledge of how coparenting may change during marital therapy.     

Building relationships on social networking sites from a social work approach

ABSTRACT

Our current age of connectedness has facilitated a boom in interactive dynamics within social networking sites. It is, therefore, possible for the field of Social Work to draw on these advantages in order to connect with the unconnected by strengthening online mutual support networks among users.

The aim of this article is to examine whether ‘connectedness’ in social networking sites improves online social capital and resilience of social service users.

Through our analysis of social networks carried out on an experimental model, we observed the patterns of connectedness on Facebook of 50 social service end-users from Málaga, Spain. The detection of online communities through the modularity algorithm has allowed us to ascertain whether individuals’ offline realities mirror their online realities. At the same time, we examined the influence certain interactions (likes, comments, etc.) have on leadership through online ethnography. Finally, online social capital, understood as the combination of connectedness and online interaction, has been correlated with users’ resilience. The results reveal that both connectedness and interaction feed themselves and have correlations with resilience.

Construction and Evolution of a Multidimensional Well-Being Index for the Spanish Regions

The study presented here is an attempt to calculate a comparative multidimensional index of economic well-being for the Spanish Autonomous Communities. Based on the dimensions of adjusted consumption, real wealth, equity and economic security per inhabitant, we obtain one relative index using a system of uniform weightings, a second resulting from a factor analysis and a third provided by a DEA analysis. We elaborate the index for the year 2000 and for 2006, thereby providing the relative results with greater robustness and permitting some conclusions to be reached with regard to the evolution over time of the index.
