Factors Associated with Gamblers: A Population-based Cross-sectional Study of South Australian Adults

Objective To determine, using a random telephone survey, the prevalence of various gambling activities among South Australian adults, the prevalence of adult problem gamblers using the South Oaks Gambling Screen (SOGS) instrument, and to examine the problem gamblers by demographic and health-related risk factors.Method A random representative sample of South Australian adults selected from the Electronic White Pages. Overall, 6045 interviews were conducted (73.1% response rate) using Computer Assisted Telephone Interviewing (CATI) technology.Results Overall, 75.6% (95% CI: 74.5–76.7) of respondents had participated in at least one gambling activity during the last 12 months and 2.0% (95% CI: 1.7–2.4) were identified to be problem gamblers. A wide range of factors was associated with problem gambling at a univariate level, when compared to frequent gamblers. The logistic regression analysis highlighted that problem gamblers were more likely to speak a language other than English, be employed part time and a smoker when compared to frequent gamblers. Problem gamblers were also more likely to have a mental health condition (according to the Kessler 10), have had suicidal thoughts and know of services for gambling problems.Conclusion There is a wide range of characteristics associated with problem gambling in South Australia. All of these factors need addressing during policy development to assist problem gamblers.     

Information and Communication Technologies: Reshaping Voluntary Organizations?

Electronic networking holds the promise of innovation with involuntary organizations as they seek to respond to deep shifts in the social, economic, and political spheres in which they operate. Evidence from our study of U.K. voluntary organizations demonstrates relatively low uptake of the core networking technologies and applications essential to support the reconfiguration of key relationships in and around the organizations. Friends of the Earth and the Samaritans are exceptions to this trend. Case studies of these organizations suggest they are using information and communication technologies to reshape internal relationships and reconfigure relationships externally. The extent to which the organizations are reconfiguring around intelligent campaigning and intelligent client service is tempered by their long‐standing values.     

On boosting kernel density methods for multivariate data: density estimation and classification

Statistical learning is emerging as a promising field where a number of algorithms from machine learning are interpreted as statistical methods and vice-versa. Due to good practical performance, boosting is one of the most studied machine learning techniques. We propose algorithms for multivariate density estimation and classification. They are generated by using the traditional kernel techniques as weak learners in boosting algorithms. Our algorithms take the form of multistep estimators, whose first step is a standard kernel method. Some strategies for bandwidth selection are also discussed with regard both to the standard kernel density classification problem, and to our 'boosted' kernel methods. Extensive experiments, using real and simulated data, show an encouraging practical relevance of the findings. Standard kernel methods are often outperformed by the first boosting iterations and in correspondence of several bandwidth values. In addition, the practical effectiveness of our classification algorithm is confirmed by a comparative study on two real datasets, the competitors being trees including AdaBoosting with trees.     

Adolescent Depression as a Contributing Factor to the Development of Substance Use Disorders

An exploratory investigation of the variables linking adolescent substance abuse and depression was conducted using the “grounded theory” qualitative research approach. A convenience sample was drawn from African American adolescents, aged 12 to 18 years, who reside in a public housing community in Baltimore, Maryland. The results revealed approximately 5% of the sample openly admitted to using drugs because they are sad, feel like a failure, lack energy and because they have family problems. Moreover, 26% of the respondents reported drinking alcoholic beverages; 26% of the population reported smoking marijuana and 16% of the respondents reported they smoke cigarettes. Additionally, life stressors (i.e. an absent parent from the home, childhood illnesses, family discord, living in kinship or foster care environments, living in single-parent households and unemployment) are adversely impacting the lives of African American adolescents residing in a public housing community.     

Ethics and social media: Implications for sociolinguistics in the networked public1

As a popular agora for writing identity into being, the networked public of social media sites presents exciting and unprecedented possibilities for sociolinguistic research. At the same time, these sites raise a wealth of unfamiliar methodological and ethical issues, and debate concerning appropriate ethical measures for research targeting online discourse communities is emergent. One of the most pressing debates concerns the visibility of online interaction (i.e. its locus between the public and private ends of the continuum). Although they exist freely online, networked publics are not public forums. They are governed by both personal and communal norms, and they are networked. This combination of factors gives rise to unique ethical challenges, particularly in the case of Facebook, an accessible and data‐rich, yet problematic, research site. This paper reviews the ethical difficulties presented by Facebook, and presents a framework for ethnographic sociolinguistic research that uses this site as a source of data. En tant qu’espace public privilégié pour la création de l’identitéà travers l’écriture, le public ?réseauté? (interconnecté) des sites des médias sociaux présente des possibilités prometteuses et sans précédent pour la recherché en sociolinguistique. Cependant, ces sites soulèvent de nombreuses questions méthodologiques et éthiques qui sont nouvelles, d’où l’émergence de discussions portant sur les mesures éthiques appropriées pour la recherche qui vise les communautés discursives en ligne. Un des débats concerne la visibilité de l’interaction en ligne (c.‐à‐d. sa place entre les extrémités privée et publique du continuum). Bien qu’ils existent de façon libre en ligne, les réseaux publics ne sont pas des forums publics. Ils sont gouvernés à la fois par des normes personnelles et communautaires, et ils sont interconnectés. Cette combinaison de facteurs donne naissance à des défis éthiques uniques, en particulier dans le cas de Facebook, un site de recherche accessible et riche en données, mais problématique. Cet article passe en revue les difficultés éthiques que Facebook présente, et offre un cadre de travail pour la recherche sociolinguistique ethnographique utilisant ce site comme source de données.

Tourist profiles using discriminant analysis

How similar are tourists from the audiences of two or more advertising vehicles? The method of N-way multiple discriminant analysis was used for predicting magazine readership from key tourist variables from two samples of 300 coupon inquiries. Results of the analysis indicated similar tourist profiles existed among the readerships of the three magazines. Application of the method used in this study may be useful in the development of promotional themes to attract tourists from selected advertising vehicles and in identifying unique tourism characteristics for particular vehicles.
