Reducing the Floor Effect in the SF-6D: A Feasibility Study

The SF-6D suffers from a floor effect where for patient groups in severe health a significant number of patients report the lowest level of health possible for some dimensions, meaning the SF-6D cannot capture a deterioration in health for these patients. This paper presents a feasibility study aimed at reducing this floor effect. A modified SF-6D classification system was proposed that incorporated an additional level in each of the physical functioning and role limitations dimensions. The modified classification system was valued by a Portuguese general population sample (n = 140) using the Portuguese SF-6D protocol. A sample of 82 health states were valued and several regression models were estimated to produce preference weights to predict health state values for all states defined by the modified classification system. Estimations at the individual level were performed using 950 health state valuations. Models were analyzed in terms of logical consistency of coefficients, overall fit and predictive ability and were compared to Portuguese SF-6D models. The additional severity levels included in the modified classification system have significant decrements in health state values. These additional severity levels do not significantly impact on the modelled preference weights (the regression coefficients) of other levels across all dimensions. This feasibility study modified the SF-6D to reduce the floor effect. This study presents one option and further research in this area is encouraged.     

Cognitive Socialization Across Ethnocultural Contexts: Literacy and Cultural Differences in Intellectual Performance and Parent-Child Interaction

A comparative study of parent-child interaction and its relation to children's intellectual achievement is presented. The question of cultural continuities in cognitive development was examined. The cross-national design also illustrates some of the problems encountered when such relationships are studied across social contexts in general. The results suggest that although interaction characteristics are related to children's intellectual achievement, that relation is moderated by context factors that may operate differently in each culture. The findings are discussed in terms of how literacy mediates parents' teaching styles in ways that remain culturally ingrained. Research issues and recommendations for future research and policy are discussed.     

Goal Orientation and Work Role Performance: Predicting Adaptive and Proactive Work Role Performance Through Self-Leadership Strategies

This article explores the relationship between goal orientation, self-leadership dimensions, and adaptive and proactive work role performances. The authors hypothesize that learning orientation, in contrast to performance orientation, positively predicts proactive and adaptive work role performances and that this relationship is mediated by self-leadership behavior-focused strategies. It is posited that self-leadership natural reward strategies and thought pattern strategies are expected to moderate this relationship. Workers (N = 108) from a software company participated in this study. As expected, learning orientation did predict adaptive and proactive work role performance. Moreover, in the relationship between learning orientation and proactive work role performance through self-leadership behavior-focused strategies, a moderated mediation effect was found for self-leadership natural reward and thought pattern strategies. In the end, the authors discuss the results and implications are discussed and future research directions are proposed.     

South American Evangelicals’ Re-conquest of Europe

This article focuses on networks of South-American preachers, led by charismatic characters such as the Argentinean pastor Carlos Annacondia, who export themselves not only to countries within the Americas but also to Europe. The prevailing justification among Latin-American Evangelicals for undertaking this ‘reverse mission’ (Freston) is in the view that especially the ‘old’ Roman Catholic Europe is spiritually ‘cooled down’ and that the time is ripe for re-evangelizing it. This study analyzes the way in which network-based charismatic entrepreneurship has encouraged transnational imaginaries of re-conquering Europe spiritually, more specifically in terms of the meanings the members of these networks attribute to the ‘spiritual re-conquest’. I conclude by suggesting that, similar to flows from other regions in the global South, such as Africa, the much vaunted ‘reverse mission’ to Europe is vested with meanings that transcend the spiritual re-conquest as such. In the case of Latin America, this article argues, the chief motivation is symbolic: to strengthen the status of local churches and their leaders against the backdrop of a highly competitive religious market on the Latin-American sub-continent.     

Structural model of acculturation attitudes and related psychosocial variables: Empirical evidence in native Spaniards

This work falls within the framework of the study of acculturation processes of natives and immigrants. Its goal is to test an explanatory multi‐group model of natives' acculturation attitudes as a function of diverse psychosocial variables: Prejudice and natives' appraisal of their own culture (in a direct way) and inter‐group contact and perceived inter‐group similarity (in an indirect way). Participants were 499 Spaniards surveyed for their attitude towards Romanian immigrants and 493 towards Ecuadorian immigrants. The indicators used took into account three socio‐cultural spheres: peripheral, intermediate and central areas. This multi‐group model shows an adequate fit to the data.     

The effects of age and emotional valence on recognition memory: An ex‐Gaussian components analysis

The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex‐Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The τ parameter, often related to attention in the literature, was smaller for young than old participants in an ex‐Gaussian fit. Differences on the τ parameter might suggest poorer attentional performance in old participants.     

Measurement Invariance of the Adolescent Quality of Life-Mental Health Scale (AQOL-MHS) across Gender,Age and Treatment Context

The Adolescent Quality of Life-Mental Health Scale (AQOL-MHS) was designed to measure quality of life in clinical samples of Latino adolescents aged 12–18 years, but has also been used in community samples. The original measure included three factors: Emotional Regulation (ER), Self-Concept (SC) and Social Context (SoC). The goals of this study are to replicate the factor structure using confirmatory factor analysis (CFA), shorten the instrument and test the degree of measurement invariance across gender, age, and type of sample. Participants for the analyses (N?=?354) came from two populations in the San Juan Metropolitan Area: (1) adolescents from randomly selected households, using a multi-stage probability sampling design (n?=?295), and (2) adolescents receiving treatment at mental health clinics (n?=?59). We first carried out a conceptual item analysis for item reduction purposes and then assessed dimensional, configural, metric and scalar invariance for each factor using the Mplus software system. The original 3-factor structure was replicated with comparable model fit in each treatment context. Metric invariance was attained for all three scales across groups. Either full or partial scalar invariance was also observed with DIF in a total of 6 items. Invariance testing supports the use of the abridged 21 item version of the AQOL-MHS to compare diverse individuals with little bias using observed scores, but for refined estimates the ideal scoring will be from a latent variable model.     

Appropriating Video Surveillance for Art and Environmental Awareness: Experiences from ARTiVIS

Arts, Real-Time Video and Interactivity for Sustainability (ARTiVIS) is an ongoing collaborative research project investigating how real-time video, DIY surveillance technologies and sensor data can be used as a tool for environmental awareness, activism and artistic explorations. The project consists of a series of digital contexts for aesthetic contemplation of nature and civic engagement, aiming to foster awareness and empowerment of local populations through DIY surveillance. At the core of the ARTIVIS efforts are a series of interactive installations (namely B-Wind!, Hug@tree and Play with Fire), that make use of surveillance technologies and real-time video as raw material to promote environmental awareness through the emotion generated by real-time connections with nature. Throughout the project development, the surveillance concept has been shifting from the use of surveillance technology in a centralized platform, to the idea of veillance with distributed peer-to-peer networks that can be used for science and environmental monitoring. In this paper we present the history of the ARTiVIS project, related and inspiring work, describe ongoing research work and explore the present and future challenges of appropriating surveillance technology for artistic, educational and civic engagement purposes.
