Mobile Technology and Boundary Permeability

An extensive review of the literature reveals a lack of insight into why some employees and their families benefit from the adoption of mobile technology while others do not. The paper summarizes the authors' efforts to answer this question. The authors undertook a longitudinal case study of the adoption and use of a BlackBerry Smartphone by 25 professional knowledge workers. Four theoretical lenses were used to help with the data analysis process: boundary theory, the social constructivist view of technology, sensemaking and attribution theory. Analysis of the Time 2 data identified three groups. Segmentors (n = 4) did not use their smartphones outside work hours. Integrators (n = 8), used their smartphones to connect to both work and family anywhere, but not any time (temporally separated work and family roles). Struggling segmentors (n = 13) felt pressured by their organization to use their device 24/7 and did so. The analysis indicates that the relationship between the use of mobile technology and successful boundary management depends on the development of a strategy to manage the device prior to adoption, the ability to change one's strategy to respond to concerns at home, and self‐control.     

Work orders: Analysing employment histories using sequence data

The analysis of employment histories has been facilitated recently by advances in survey methodology, statistical processes and computing power. While much work has focused on transitions between states and time spent in one state, the potential of analysing a series of states (i.e. careers) has largely been ignored. A concentration on movement between two states, whilst allowing relevant contextual covariates to be controlled for, often ignores valuable data both prior to and after the episode in question. Analysis of extended sequences of employment states is better able to describe employment trajectories. Furthermore, comparison of sequences permits either allocation to theoretical categories, or the identification of latent groupings using cluster analysis. The resulting typology of careers can then be used in inferentially based analyses. This paper explores sequence analysis using Optimal Matching Analysis (OMA). OMA is explained in relation to one broad substantive issue: the relationship between employment trajectories and gender.     

An Examination of Factors Driving Chinese Gamblers’ Fallacy Bias

Gambling is a leisure activity, which is enjoyed by many people around the world. Among these people, Chinese are known for their high propensity to gamble and are highly sought after by many casinos. In this exploratory study, the effect of two types of fallacy bias—positive recency and negative recency—on the betting behavior of Chinese gamblers is investigated. Although the influence of fallacy bias on a betting decision is well documented, little is known about the interaction of the factors that dictate fallacy bias. Drawing from an analysis of 2,645 betting decisions, the results show that Chinese gamblers primarily endorse positive recency, especially when the latest outcome is more frequent. This is contrary to most findings on Western subjects in which negative recency is more common. Current findings have meaningful implications to casino gaming entertainment businesses and public policymakers.     

Improving Food Safety in the Domestic Environment: The Need for a Transdisciplinary Approach

Microbial food safety has been the focus of research across various disciplines within the risk analysis community. Natural scientists involved in food microbiology and related disciplines work on the identification of health hazards, and the detection of pathogenic microorganisms. To perform risk assessment, research activities are increasingly focused on the quantification of microbial contamination of food products at various stages in the food chain, and modeling the impact of this contamination on human health. Social scientists conduct research into how consumers perceive food risks, and how best to develop effective risk communication with consumers in order to improve public health through improved food handling practices. The two approaches converge at the end of the food chain, where the activities regarding food preparation and food consumption are considered. Both natural and social sciences may benefit from input and expertise from the perspective of the alternative discipline, although, to date, the integration of social and natural sciences has been somewhat limited. This article therefore explores the potential of a transdisciplinary approach to food risk analysis in terms of delivering additional improvements to public health. Developing knowledge arising from research in both the natural and social sciences, we present a novel framework involving the integration of the two approaches that might provide the most effective way to improve the consumer health associated with food-borne illness.     

Generalized Additive Modelling of Mixed Distribution Markov Models with Application to Melbourne's Rainfall

The paper considers the modelling of time series using a generalized additive model with first-order Markov structure and mixed transition density having a discrete component at zero and a continuous component with positive sample space. Such models have application, for example, in modelling daily occurrence and intensity of rainfall, and in modelling numbers and sizes of insurance claims. The paper shows how these methods extend the usual sinusoidal seasonal assumption in standard chain-dependent models by assuming a general smooth pattern of occurrence and intensity over time. These models can be fitted using standard statistical software. The methods of Grunwald & Jones (2000) can be used to combine these separate occurrence and intensity models into a single model for amount. The models are used to investigate the relationship between the Southern Oscillation Index and Melbourne's rainfall, illustrated with 36 years of rainfall data from Melbourne, Australia.     

Independent lives and the relevance of lifetime homes

A problem for disabled people, particularly individuals dependent on the use of a wheelchair, is housing that is not easily usable due to physical barriers. A proposed solution by government is the adoption of lifetime homes (LTH) standards that are likely to become mandatory for all newly constructed dwellings in the private sector in England by 2008. It is, therefore, an appropriate time to take stock of LTH standards, and to evaluate to what extent they are able to address the problems for disabled people caused by physically inaccessible housing. In doing so, the article provides a critique of LTH standards, and suggests that while they are, in some respects, a positive development, they are not, in and of themselves, a panacea in relation to rectifying the shortfall of accessible dwellings.     

Social Work,Social Policy and the Journal

There are problems associated with mainstream sociological and criminological research into youth violence. Conventional frameworks ignore the interpretive component of violence and thus fail to treat youth violence as a form of action in which motivations, moral impulses and feelings are constitutive of the action. Young people historically have had little opportunity to enter into dominant discourses about violence. This paper reports on the accounts of 29 young people who have been directly involved in violence. Those young people were asked to define violence and describe what personal and collective meanings they attach to their actions.
