Relationship based social work practice: the case for considering the centrality of humour in creating and maintaining relationships

Relationship based social work practice has received increasing attention in recent years. The use of humour has infrequently been considered in relation to social work, and humour use is a neglected aspect in examining relationships in social work. As humour conveys humanity, is grounded in our earliest attachments and in the management of emotions, the purpose of this paper is to consider how humour operates in social work relationships. Importantly humour can help facilitate relationships with service users, and become a tool to help service users, social workers and their colleagues establish relationships.     

Contrasting effects of urban habitat complexity on metabolic functional diversity and composition of litter and soil bacterial communities

Functional diversity and composition of soil bacterial communities affect important soil biogeochemical processes. In natural and semi-natural ecosystems, variations in habitat complexity have been shown to significantly impact both litter and soil bacterial communities. However, this remains largely untested in urban ecosystems, where human management can lead to habitat complexity combinations unobserved in rural ecosystems. We established 10 research plots in low-complexity park, high-complexity park, and high-complexity remnant habitat types (n = 30) in Melbourne, Australia. The use of organic carbon substrates by soil and litter bacteria was measured using EcoPlates to investigate the effects of habitat complexity upon metabolic functional diversity and functional composition of bacterial communities of i) soil and ii) one-year old litter. Direct and indirect effects of habitat complexity, microclimate and decomposition status upon litter microbial functional diversity and composition were also modelled using path analysis. Soil bacterial communities had significantly higher functional diversity compared to litter bacterial communities, but no significant effect of habitat complexity was apparent. The functional composition of soil bacterial communities was not affected by habitat complexity. In contrast, the functional composition of litter bacterial communities in high complexity parks and remnants was significantly different from that in low-complexity parks. The functional composition of litter bacterial communities, but not their diversity, was directly affected by habitat complexity and microclimate as well as their indirect effects upon the decomposition status of litter. Human management of urban habitat complexity can alter the functional composition of litter and soil bacterial communities without affecting their functional diversity. While this can have significant impacts on bacteria-regulated processes and ecosystem services, it also suggests that urban bacterial communities might be able to adjust to further environmental and climatic changes affecting urban ecosystems.     

A comparison of the Hosmer–Lemeshow,Pigeon–Heyse,and Tsiatis goodness-of-fit tests for binary logistic regression under two grouping methods

Algebraic relationships between Hosmer–Lemeshow (HL), Pigeon–Heyse (J²), and Tsiatis (T) goodness-of-fit statistics for binary logistic regression models with continuous covariates were investigated, and their distributional properties and performances studied using simulations. Groups were formed under deciles-of-risk (DOR) and partition-covariate-space (PCS) methods. Under DOR, HL and T followed reported null distributions, while J² did not. Under PCS, only T followed its reported null distribution, with HL and J² dependent on model covariate number and partitioning. Generally, all had similar power. Of the three, T performed best, maintaining Type-I error rates and having a distribution invariant to covariate characteristics, number, and partitioning.     

Estimating and contextualizing the attenuation of odds ratios due to non collapsibility

The odds ratio is a measure commonly used for expressing the association between an exposure and a binary outcome. A feature of the odds ratio is that its value depends on the choice of the distribution over which the probabilities in the odds ratio are evaluated. In particular, this means that an odds ratio conditional on a covariate may have a different value from an odds ratio marginal on the covariate, even if the covariate is not associated with the exposure (not a confounder). We define the individual odds ratio (IORs) and population odds ratios (PORs) as the ratio of the odds of the outcome for a unit increase in the exposure, respectively, for an individual in the population and for the whole population, in which case the odds are averaged across the population. The attenuation of conditional odds ratio, marginal odds ratio, and PORs from the IOR is demonstrated in a realistic simulation exercise. The degree of attenuation differs in the whole population and in a case–control sample, and the property of invariance to outcome-dependent sampling is only true for the IOR. The relevance of the non collapsibility of odds ratios in a range of methodological areas is discussed.     

Tabulations for value at risk and expected shortfall

Value at risk and expected shortfall are the two most popular measures of financial risk. Here, we tabulate expressions for both these measures for over 100 parametric distributions, including all commonly known distributions, and illustrate a data application. We expect that this collection of expressions could serve as a source of reference and encourage further research with respect to measures of financial risk.     

On-the-Job Search,Mismatch and Worker Heterogeneity

This paper empirically examines the search behavior of currently employed workers to understand changes in on-the-job search across different types of employed individuals and varying labor market conditions. Using data from the American Time Use Survey, we estimate the responsiveness of workers with varying levels of productivity and job-match quality to regional labor market conditions. We find that those workers who are less-productive, mismatched in their current position, and high-productivity, mismatched workers are more likely to engage in search than other workers. These results have implications for models built on job mismatch, as well as for models seeking to explain increasing inequality and wage dispersion.     

Guanxi influence and talent management in Chinese organisations; evidence from the real estate sector

The Chinese context has been characterised as one where guanxi influence is significant, shaping the choices, considerations, challenges, and consequences of talent management (TM). There is though little empirical research which shows that this is what is experienced, and that guanxi influence does feature prominently. The purpose of our research is to explore experiences of TM in China, and the extent to which the guanxi influence affects TM.

Case study research to identify and explore guanxi influence on TM was undertaken in three real estate companies in China. Interviews with managers and employees on how talent is defined, attracted, developed, and retained were analysed for guanxi influence. These show that guanxi influence is clearly present in the experience of TM, though this is not the sole or always dominant influence on choices, considerations, challenges, and consequences. This paper contributes to the TM literature by showing that guanxi influences play important roles in defining, attracting, developing, and retaining talent in the Chinese context and also highlighting both advantages and potential disadvantages of guanxi influence in TM activities.

Evidence suggests that guanxi influence is a relevant focus for understanding TM and for framing further research on TM in China. Guanxi influence in this TM context will continue, and by extension in contexts where Chinese organisations develop their presence globally, and adapt to the wider international context of organisation development and change in which best practice TM is a stronger influence.     

Australian Queer Science Fiction Fans

Science fiction (sf) does more than provide a fleeting moment of entertainment; it has many personal and social functions. In addition to offering audiences “romantic escapism” (Gerrold, 1996, pp. 5–6), sf also enables the “postulation of an alternative reality from which to contemplate this one” (Gerrold, 1996, pp. 5–6); as such, it is especially important “for groups which have had limited stakes in the status quo” (Jenkins, 1995, p. 242). To date, no research has been undertaken on the relationship between Australian queers and sf fandom. This article reports the findings of an online survey and explores the psycho-social features of Australian queer sf fans and why they like the genre. While the characteristics of this sample mirror those of Australian queers generally, they also have slightly higher rates of mental illness and are far more likely to state they have “no religion.” Furthermore, while enjoying the “sciency” (P10, bisexual woman) aspects of sf, Australian queers also like the “poignant metaphors for our own civilization” (P45, asexual man)     

Socializing the Silent Treatment: Parent and Adult Child Communicated Displeasure,Identification, and Satisfaction

Responding to evidence that the silent treatment is a relational-harming means of communicating disappointment in interpersonal relationships, this study focused on the silent treatment’s role and transmission within the family. Adult children’s (N = 182) self-reported silent-treatment behaviors were negatively related to their own self-esteem, and the satisfaction they reported for their primary parent was negatively related to that parent’s silent treatment. The parent’s admitting displeasure, however, was positively related to this satisfaction and positively associated with the child’s feelings of control. Revealed sex differences were minor and outside of gendered expectations for communicating disappointment. In testing parent socialization of the silent treatment, parent silent-treatment use was positively associated with the adult child’s silent-treatment use, with no demonstrated mediation by parent identification.
