The efficacy of a psychosocial intervention for HIV/AIDS caregiving dyads and individual caregivers: a controlled treatment outcome study

The present study examined the comparative efficacy of intervening at the caregiver/care-recipient dyadic level, versus the individual caregiver level, for caregivers and their care-recipients with HIV/AIDS. Participants were randomly assigned to a Dyad Intervention (DI), a Caregiver Intervention (CI) or Wait List Control group (WLC), and assessed by interview and self-administered scales immediately before treatment and eight weeks later. Participants in the intervention groups also completed a four-month follow-up assessment. Dependent variables included global distress, social adjustment, dyadic adjustment, subjective health status, HIV/AIDS knowledge and target problem ratings. Results showed that caregivers in the DI group showed greater improvement from pre- to post-treatment on global distress, dyadic adjustment and target problems than the CI and WLC caregivers. The CI and DI caregivers showed greater improvement than the WLC group on all dependent variables except social adjustment. Care-recipients in the DI group improved significantly from pre- to post-treatment on dyadic adjustment, social adjustment, knowledge, subjective health status and Target Problem 1, whereas the CI and WLC care-recipients failed to improve on any of these measures. The treatment gains made by the DI caregivers and care-recipients on most dependent variables were maintained at a four-month follow-up. Findings support a reciprocal determinism approach to the process of dyadic adjustment and suggest that intervening at the caregiver/care-recipient level may produce better outcomes for both the caregiver and care-recipient than intervening at the individual caregiver level.

Supply chain management as beyond operational efficiency

The orthodoxy of supply chain management (SCM) emphasises competitive advantage through increased operational efficiency and market responsiveness from production and distribution processes into the hands of consumers. It anticipates that future competition will be between chains rather than between firms. While well established in other industry sectors, the SCM concept is newly developed in the Australian agri-food sector. Critical review of the concept has identified key issues of power among channel members, processes of chain initiation and innovation, and the inability of SCM to offer a viable business strategy for some firms. Building on those insights, this paper examines the supply chain concept for horticulture. Horticultural products are characterised by perishability, heterogeneity and lags in production response to market signals. Producers’ profits are vulnerable to quantity, timing of supply and product specification. Many supply chains in smaller industries are loose, fragmented, interwoven, unstable and unique! Firms operating within these environments need an astute understanding of the chains, the hierarchy of channel members and their relative position. Effective business strategies – for individual firms and supply chains - need to be developed and redeveloped to accommodate the dynamic nature of horticulture. Two case studies are discussed as contributions to this early stage of the theoretical development of supply chain management. The SCM concept also has implications for horticultural researchers, involving a wider range of industry stakeholders, technical problems and research skills. As for business management, the usefulness of the concept will depend on its capacity to increase responsiveness to customers’ preferences and customer value.

Preferences of domestic and imported mandarins in Bali, Indonesia

Four focus group discussions were held to determine the salient attributes of mandarins in the minds of Balinese consumers. Taste panel findings of 26 untrained panellists showed that imported mandarins were significantly preferred for taste, texture and overall quality. Domestic mandarin segments averaged higher than imported ones on appearance, but the difference was not significant. Gold skin colour was preferred.

Alcohol, tobacco and breast cancer - collaborative reanalysis of individual data from 53 epidemiological studies, including 58 515 women with breast cancer and 95 067 women without the disease

Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58515 women with invasive breast cancer and 95067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19 - 1.45, P < 0.00001) for an intake of 35 - 44 g per day alcohol, and 1.46 (1.33 - 1.61, P < 0.00001) for greater than or equal to 45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P

Characterisation of multiple Caribbean ciguatoxins and congeners in individual specimens of horse-eye jack (Caranx latus) by high-performance liquid chromatography/mass spectrometry

We studied the variation in toxin profiles of purified extracts of 10 individual specimens and two pools of ciguateric Caranx latus. High-performance liquid chromatography/mass spectrometry (HPLC/MS) identified in all individual samples at least seven Caribbean ciguatoxins (C-CTXs) comprising C-CTX-1 and its epimer C-CTX-2 ([M + H](+) m/z 1141.58), and five new C-CTX congeners with pseudo-molecular ions at m/z 1141.58, 1143.60, 1157.57, 1159.58, and 1127.57. In some samples, additional C-CTX isomers were detected with [M + H](+) ions at m/z 1141.58 (two), 1143.60 (one) and 1157.57 (two). The two low-toxic pools contained only four to six ciguatoxins. The comparison in relative proportions of four different mass classes ([M + H](+) at m/z 1141, 1143, 1157 and 1127) showed that the group at m/z 1157 increased (2-20%) with flesh toxicity. More than 80% of group m/z 1141 comprised C-CTX-1, C-CTX-2 and their isomer C-CTX-1 a whose level in this group correlated with fish toxicity. Contrary to low-toxic fishes, high-risk specimens had C-CTX-1 levels

Play Preferences and Behavior of Preschool Children with Autistic Spectrum Disorder in the Clinical Environment

The play of children with autistic spectrum disorder (ASD) is a valuable medium for assessment and intervention, and its analysis has the potential to aid diagnosis. This study investigated spontaneous play behavior and play object preferences for 24 preschool children with ASD in a typical occupational therapy clinical environment. Play behavior was rated and choice of play object noted at 10-second intervals from a 15-minute video recording of unstructured play. Statistical analyses indicated that play behavior was consistent with descriptions in the literature. In addition, the children demonstrated clear preferences for play objects in the form of popular characters (e.g., Thomas the Tank Engine) and those with sensorimotor properties. We propose that the inclusion of preferred play objects in a clinical environment may increase intrinsic motivation to play, and thereby enhance assessment and intervention.

Democracry and the Individual

The main question informing this paper is whether it is possible to extend democracy beyond its liberal forms. The paper reflects upon this question with regard to its implications for the individual. For the radicalization of democracy implies a need for self-transformation, if the everyday egoism of contemporary citizens is not to thwart reasonable discussion and participation. Theorists such as Richard Rorty argue that the philosophical resources required to guide such self-transformation can be made available only by sacrificing the political freedom and cultural diversity liberalism has been able to precariously establish. Other theorists insist that the thresholds of pluralism and tolerance that existing liberal democracies are struggling to maintain actually require an extension of democracy. The paper evaluates two different theoretical strategies that aim to identify potentials for democratization without falling prey to the dilemma identified by Rorty: a ‘ deliberative’ strategy explicated with reference to Jürgen Habermas and an ‘existential’ approach represented here by William Connolly.

Physical activity and sedentary behavior: A population-based study of barriers, enjoyment, and preference

The associations of physical activity and sedentary behavior with barriers, enjoyment, and preferences were examined in a population-based mail survey of 1,332 adults. Respondents reporting high enjoyment and preference for physical activity were more likely to report high levels of activity. Those reporting cost, the weather, and personal barriers to physical activity were less likely to be physically active. Preference for sedentary behavior was associated with the decreased likelihood of being physically active, and the weather as a barrier to physical activity was associated with the increased likelihood of sedentary behavior. These constructs can be used to examine individual and environmental influences on physical activity and sedentary behavior in specific populations and could inform the development of targeted interventions.
