Delivering decision making support to people with cognitive disability — What has been learned from pilot programs in Australia from 2010 to 2015

The UNCRPD has generated debate about supported decision making as a way to better enable people with cognitive disability to participate in decision making. In Australia, between 2010–2015, a series of projects have piloted various models of delivering decision making support. A critical review was conducted on the program documents and evaluations of these pilot projects. The pilots were small scale, conducted by both statutory and non‐statutory bodies, and adopted similar designs centred on supporting a decision maker/supporter dyad. Primarily, participants were people with mild intellectual disability. Themes included: positive outcomes; uncertain boundaries of decision support; difficulty securing supporters; positive value of program staff and support to supporters; limited experience and low expectations; and varying value of written resources. The lack of depth and rigour of evaluations mean firm conclusions cannot be reached about program logics, costs or outcomes of the pilots. The pilots demonstrate feasibility of providing support for decision making rather than resolving issues involved in delivering support. They suggest that some form of authority may facilitate the role of decision supporters, help to engage others in a person's life, and integrate decision making support across all life domains.     

Handing down the farm? The increasing uncertainty of irrigated farm succession in Australia

Farming is still primarily a family concern in Australia. Having a farm successor in place is important as it is associated with the likelihood of the current farmer adapting to external conditions and hence may have long-term implications for the structure and profitability of agriculture. We used current and historical surveys across a number of irrigation districts in the southern Murray-Darling Basin to study the changing nature of farm succession. Irrigation farms with (and without) a named successor have decreased over time, while uncertainty about succession has increased rapidly. There was strong evidence that the identification of a successor is positively associated with the current and future management of farms. Those with no successor in place are more likely to go into a period of stagnation (such as selling land, not adopting efficient irrigation infrastructure and not increasing irrigated area). One key finding is that increasing uncertainty about succession among irrigated farmers in recent years has been influenced by issues surrounding water security in the Murray-Darling Basin.     

Family Influences on Mexican American Adolescents’ Romantic Relationships: Moderation by Gender and Culture

This study examined prospective associations between the family context and adolescents’ romantic relationships as moderated by adolescents’ gender and culture among Mexican American families (N = 189). Adolescents at Time 1 (early adolescence) were on average 12.29 years of age (SD = 0.50) and 54% female. Mothers and fathers reported on family structure and dynamics during early adolescence, and youth reported on their romantic relationship involvement and quality during middle and late adolescence. Results from path analyses indicated that family structure and dynamics (supportive parenting, consistent discipline, and parent–adolescent and interparental conflict) were associated with adolescents’ romantic involvement and quality, and with differences by adolescents’ gender and culture. Findings highlight Mexican American family contexts that contribute uniquely to adolescents’ romantic relationships.     

Implications of parents’ work travel on youth adjustment

Guided by ecological, work–family spillover and crossover frameworks, this study examined mechanisms linking parental work travel (i.e. nights per year) to youth adjustment (i.e. externalizing and internalizing behaviours) through youth’s perceptions of parenting (i.e. knowledge, solicitation) with traveller and youth gender as moderators in a sample of 78 children in 44 two-parent families residing in the United States. The findings from multilevel analyses suggested that mothers’ travel nights predicted lower levels of maternal knowledge, with variation by traveller and youth gender. Mothers’ and fathers’ work travel and perceived parenting were predictors of youth’s externalizing behaviours, whereas only fathers’ work travel and perceived parenting were predictors of youth’s internalizing behaviours. Tests of indirect effects indicated that maternal work travel linked to youth’s externalizing behaviours through youth’s perceptions of maternal knowledge. These findings add to our limited understanding of work–family issues for parents who have the unique work demand of frequently travelling.     

Properties of Model-Averaged BMDLs: A Study of Model Averaging in Dichotomous Response Risk Estimation

Model averaging (MA) has been proposed as a method of accounting for model uncertainty in benchmark dose (BMD) estimation. The technique has been used to average BMD dose estimates derived from dichotomous dose-response experiments, microbial dose-response experiments, as well as observational epidemiological studies. While MA is a promising tool for the risk assessor, a previous study suggested that the simple strategy of averaging individual models' BMD lower limits did not yield interval estimators that met nominal coverage levels in certain situations, and this performance was very sensitive to the underlying model space chosen. We present a different, more computationally intensive, approach in which the BMD is estimated using the average dose-response model and the corresponding benchmark dose lower bound (BMDL) is computed by bootstrapping. This method is illustrated with TiO(2) dose-response rat lung cancer data, and then systematically studied through an extensive Monte Carlo simulation. The results of this study suggest that the MA-BMD, estimated using this technique, performs better, in terms of bias and coverage, than the previous MA methodology. Further, the MA-BMDL achieves nominal coverage in most cases, and is superior to picking the "best fitting model" when estimating the benchmark dose. Although these results show utility of MA for benchmark dose risk estimation, they continue to highlight the importance of choosing an adequate model space as well as proper model fit diagnostics.     

Company structure and market strategy

The importance of the relationships between company strategies and structures is noted, as is the relative dearth of empirical work in this area. The article reports a preliminary study of 24 companies investigating the relationships between strategies of diversification and geographic dispersion of territories covered and structural variables relating to the number of structural differentiations in a company, the decentalization of decision-making and functional specialization. Contrary to the hypotheses proposed, these two strategic variables have different structural implications with geographic dispersion particularly associated with structural differentiation and diversification associated with decentralization.     

Transferability of probation risk-assessment instruments: A case for caution

The majority of large urban probation departments employ risk-assessment instruments to classify offenders to determine strategy of supervision. Many of these programs have adopted devices used by other jurisdictions. Some scholars, however, seriously question the universal applicability of risk-assessment instruments. The present study utilizes Survival Time Analysis to validate or test the transferability of the Georgia risk scale for a population of Houston, Texas probationers. The findings showed that after nearly 4 years at risk, the Georgia model failed to identify high-risk felony probationers but differentiated among misdemeanor risk groups. The report discusses the policy implications of these results on developing local classification procedures.     

Leader–member exchange and empowerment: Direct and interactive effects on job satisfaction,turnover intentions,and performance

This study examined the moderating impact of empowerment on the relationships between leader–member exchange (LMX) quality and the self-rated outcomes of job satisfaction and turnover intentions, as well as the supervisor-rated outcomes of job performance and organizational citizenship behaviors. Two samples, with 244 and 158 employees respectively, were used to test our hypotheses. Our results provided evidence that in general, empowerment moderates the relationships between LMX and job outcomes. These findings are important as previous research has only tested these variables as independent predictors, but our results suggest the relationships these constructs have with important consequences are dependent on both variables. Practical implications and directions for future research are offered.
