The role of the primary mental health worker (PMHW) is relatively new within child and adolescent mental health services (CAMHS). Different organisational structures have emerged and it is important to study the advantages and disadvantages associated with different PMHW practice models. The current study uses a large, representative sample of PMHWs and operationalises practice models according to the PMHWs' self‐reported location and team alignment thus identifying three models (namely CAMHS outreach, primary care based, and dedicated PMHW team). Comparisons between the models are made in relation to organisation and management, inter‐agency links, and job satisfaction with the aim of exploring the strengths and weaknesses of each model. The results suggest that each model meets the aims of the role and there is greater similarity than dissimilarity between models. However, it also indicates that attention should be paid to improving the working environments and training and development opportunities for all PMHWs irrespective of model, but with particular consideration given to improving the support available to PMHWs working in primary care based models.

The aim of this article is to examine clinical outcomes in a child psychiatry inpatient unit using dedicated measures. Clinicians completed contextual (Paddington Complexity Scale - PCS) and clinical change (Health of the Nation Outcome Scales for Children and Adolescents - HoNOSCA) questionnaires on admission and discharge for consecutive admissions to the unit between 1999 and 2007 (n=167). Mean changes in HoNOSCA scores were analysed, and the predictors of HoNOSCA mean change were assessed using regression analysis. The results showed that the mean length of stay at the unit was 5.6 months (SD 3.1). PCS ratings identified high total, clinical, and environmental complexity scores. HoNOSCA ratings indicated high levels of psychological problems on admission and significant improvement at discharge (mean change 7.7 (SD 6.7)). Greater positive change was associated with higher initial HoNOSCA scores, diagnoses other than conduct disorder and schizophrenia, and a facilitative parental attitude. The authors conclude that the systematic use of standardised outcome measures in child psychiatric inpatient units is useful to document clinical features, complexity and clinical change.

The purpose of this paper is to examine the role of a variety of developmental factors on sexual homicide offenders (SHOs), while taking into account other components of sexual homicide theoretical models.

A series of logistic regression models are performed using a total of 616 incarcerated adult male sexual offenders from Canada to distinguish between three groups of sexual offenders, SHOs, violent non-homicidal sex offenders (NHSOs) and NHSOs.

Results indicate that contrary to theoretical models, experiences of victimization are not central to the development of SHOs. Instead, it is the adoption of various problematic behaviors in childhood that appear as most important in the etiology of this particular type of sexual crime. This suggests that the various existing theoretical models of sexual homicide need to be revised and/or tested with additional empirical data.

This is the first study to look at developmental factors using two control groups of NHSOs and violent NHSOs.

Many of today’s information and technology systems and environments facilitate inquiry, learning, consciousness-raising and knowledge-building. Such platforms include e-learning systems which have learning, education and/or training as explicit goals or objectives. They also include search engines, social media platforms, video-sharing platforms, and knowledge sharing environments deployed for work, leisure, inquiry, and personal and professional productivity. The new journal, Information and Learning Sciences, aims to advance our understanding of human inquiry, learning and knowledge-building across such information, e-learning, and socio-technical system contexts.

This article introduces the journal at its launch under new editorship in January, 2019. The article, authored by the journal co-editors and all associate editors, explores the lineage of scholarly undertakings that have contributed to the journal's new scope and mission, which includes past and ongoing scholarship in the following arenas: Digital Youth, Constructionism, Mutually Constitutive Ties in Information and Learning Sciences, and Searching-as-Learning.

The article offers examples of ways in which the two fields stand to enrich each other towards a greater holistic advancement of scholarship. The article also summarizes the inaugural special issue contents from the following contributors: Caroline Haythornthwaite; Krista Glazewski and Cindy Hmelo-Silver; Stephanie Teasley; Gary Marchionini; Caroline R. Pitt; Adam Bell, Rose Strickman and Katie Davis; Denise Agosto; Nicole Cooke; and Victor Lee.

The article, this special issue, and the journal in full, are among the first formal and ongoing publication outlets to deliberately draw together and facilitate cross-disciplinary scholarship at this integral nexus. We enthusiastically and warmly invite continued engagement along these lines in the journal’s pages, and also welcome related, and wholly contrary points of view, and points of departure that may build upon or debate some of the themes we raise in the introduction and special issue contents.

The purpose of this paper is to explore the potential of enriching the library subject headings with folksonomy for enhancing the visibility and usability of the library subject headings.

The WorldCat-million data set and SocialBM0311 are preprocessing and over 210,000 library catalog records and 124,482 non-repeating tags were adopted to construct the matrix to observe the semantic relation between library subject headings and folksonomy. The proposed system is compared with the state-of-the-art methods and the parameters are fixed to obtain effective performance.

The results demonstrate that by integrating different semantic relations from library subject headings and folksonomy, the system’s performance can be improved compared to the benchmark methods. The evaluation results also show that the folksonomy can enrich library subject headings through the semantic relationship.

The proposed method simultaneous weighted matrix factorization can integrate the semantic relation from the library subject headings and folksonomy into one semantic space. The observation of the semantic relation between library subject headings and social tags from folksonomy can help enriching the library subject headings and improving the visibility of the library subject headings.
