Social identity motivations and intergroup media attractiveness

In this experiment we manipulated three features (intergroup social comparison, outgroup character stereotypicality, intergroup intimacy) of an intergroup TV pilot proposal. We examined how two underlying social identity motivations (social enhancement, social uncertainty reduction) were gratified by the aforementioned features, and whether this gratification predicted media attractiveness. Findings indicate that when social comparison was manipulated to advantage the ingroup, intergroup media gratified existing social enhancement motivations and led to audiences rating the show as more entertaining and attractive. This finding was most clearly evident in the absence of intergroup romance. The gratification of social uncertainty reduction motivations was also shown to increase audience perceptions of intergroup media attractiveness, but outgroup stereotypicality was weakly associated with the gratification of this motivation. These results are discussed in terms of both theoretical implications as well as applications to media campaigns.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Online contact, face-to-face contact and multilingualism : Young Swedish-speaking Finns develop trilingual identities

Based on the tenets of the social context model of second language acquisition, the present article examined the combined effect of online and face-to-face contact in developing multilingual skills and identities among young Swedish-speaking Finns (N = 304). The hypotheses were tested for Finnish as a second language and English as a third language using parallel models. The results were largely identical for both languages. Specifically, online contact enhanced language confidence which, in turn, contributed to language identity. However, online contact had a more substantial effect on confidence as well as identity among those who had little face-to-face contact with speakers of the given language. Findings and their implications are discussed.Peer reviewe

The effects of prototypicality and gender salience on liking and friendship potential of a female interlocutor

Drawing on self-categorization theory, this article examines the indirect effects of gender salience and prototypicality on friendship potential through increasing liking of a female interlocutor. We manipulated biographies of the fictitious interlocutor to change perceptions of prototypicality. For women, gender salience interacted with prototypicality to directly predict liking and the desire to become friends with the interlocutor indirectly through liking. Specifically, there was an interaction between prototypicality and gender salience, such that as gender salience increased, the prototypical interlocutor was liked significantly more and had higher friendship potential. For men, the same relationships did not appear. We discuss the implications of our study as well as directions for future research on intragroup communication and intergroup contexts with regard to power asymmetry

Enhancing pressure ulcer prevention using wound dressings: what are the modes of action?

Recent clinical research has generated interest in the use of sacral wound dressings as preventive devices for patients at risk of ulceration. This study was conducted to identify the modes of action through which dressings can add to pressure ulcer prevention, for example, shear and friction force redistribution and pressure distribution. Bench testing was performed using nine commercially available dressings. The use of dressings can reduce the amplitude of shear stress and friction reaching the skin of patients at risk. They can also effectively redirect these forces to wider areas which minimises the mechanical loads upon skeletal prominences. Dressings can redistribute pressure based upon their effective Poisson ratio and larger deflection areas, providing greater load redistribution.info:eu-repo/semantics/publishedVersio

'Staying strong on the inside and outside' to keep walking and moving around: perspectives from Aboriginal people with Machado Joseph Disease and their families from the Groote Eylandt Archipelago, Australia

Machado Joseph Disease (MJD) (spinocerebellar ataxia 3) is a hereditary neurodegenerative disease causing progressive ataxia and loss of mobility. It is the most common spinocerebellar ataxia worldwide. Among Aboriginal families of Groote Eylandt and related communities across Australia's Top End, MJD is estimated to be more prevalent than anywhere else in the world. This study explored lived experiences of individuals and families with MJD to determine what is important and what works best to keep walking and moving around. A collaborative qualitative exploratory study, drawing from constructivist grounded theory methods, was undertaken for data collection and analysis. Semi-structured in-depth interviews were conducted with individuals with MJD (n = 8) and their family members (n = 4) from the Groote Eylandt Archipelago where similar to 1500 Aboriginal people (Warnumamalya) live. Interviews were led by Warnumamalya community research partners in participants' preferred language(s). Participants described their experience of living with MJD, from 'knowing about MJD', 'protecting yourself from MJD' and 'adjusting to life with MJD'. While the specific importance of walking and moving around differed widely between participants, all perceived that walking and moving around enabled them to do what mattered most to them in life. 'Staying strong on the inside and outside' (physically, mentally, emotionally, spiritually) was perceived to work best to keep walking and moving around as long as possible. A framework that included personal and environmental strategies for staying strong emerged: 'Exercising your body', 'having something important to do', 'keeping yourself happy', 'searching for good medicine', 'families helping each other' and 'going country'. This study, the first to explore lived experiences of MJD in Australia, highlights the importance of maintaining mobility as long as possible. Strategies perceived to work best address physical and psychosocial needs in an integrated manner. Services supporting families with MJD need flexibility to provide individualised, responsive and holistic care

Nematode Symbiont for Photorhabdus asymbiotica

Photorhabdus asymbiotica is an emerging bacterial pathogen that causes locally invasive soft tissue and disseminated bacteremic infections in the United States and Australia. Although the source of infection was previously unknown, we report that the bacterium is found in a symbiotic association with an insect-pathogenic soil nematode of the genus Heterorhabditis

Mapping MOS-HIV to HUI3 and EQ-5D-3L in Patients With HIV

Objectives: The Medical Outcomes Study HIV Health Survey (MOS-HIV) is frequently used in HIV clinical trials; however, scores generated from the MOS-HIV are not suited for cost-effectiveness analyses as they do not assign utility values to health states. Our objective was to estimate and externally validate several mapping algorithms to predict Health Utilities Index Mark 3 (HUI3) and EQ-5D-3L utility values from the MOS-HIV. Methods: We developed and validated mapping algorithms using data from two HIV clinical trials. Data from the first trial (n = 367) formed the estimation data set for the HUI3 (4,610 observations) and EQ-5D-3L (4,662 observations) mapping algorithms; data from the second trial (n = 168) formed the HUI3 (1,135 observations) and EQ-5D-3L (1,152 observations) external validation data set. We compared ordinary least squares (OLS) models of increasing complexity with the more flexible two-part, beta regression, and finite mixture models. We assessed model performance using mean absolute error (MAE) and mean squared error (MSE). Results: The OLS model that used MOS-HIV dimension scores along with squared terms gave the best HUI3 predictions (mean observed 0.84; mean predicted 0.80; MAE 0.0961); the finite mixture model gave the best EQ-5D-3L predictions (mean observed 0.90; mean predicted 0.88; MAE 0.0567). All models produced higher prediction errors at the lower end of the HUI3 and EQ-5D-3L score ranges
