The objective of the article is to examine the way in which social work in Ireland evolved from practices of philanthropy in the late 19th century to a distinct professional strategy in the present. Results: The results of archival research show that philanthropy in Ireland was provided almost exclusively by religious organizations and was constructed within a discourse of sectarianism and rivalry between the two main denominations, Catholic and Protestant, up to the 1960s. It is only in the past 30 years that social work has become firmly established as a secular strategy. Conclusions: It is concluded that although social work is now clearly distinct from voluntary and religious-based social work practices, some of its present principles and practices remain continuous with its historical antecedents.

There has been considerable interest in recent years in comparing the operation of social work services to children and families internationally, particularly between Australia, the United Kingdom and the United States. Reviewing the respective policy environments and drawing on recent research experience in these three nations the author speculates as to how such services may be placed to respond to a converging agenda to tackle the high social and economic costs of social exclusion. It is argued that a conspiracy of circumstances have led child and family social work away from its more general child welfare objectives of the past and created consolidation of functions in relation to child protection work. This has left services ill prepared to play a central role within a new and resurgent child welfare agenda.

In 1966 the artist Antonio Lopez was rejected for the chair in “Preparatorio de colorido” (Preparatory Colouring) by the San Fernando School of Fine Arts where he himself presented his work Nevera de hielo (Ice Box). After 5 years as a “stand in” for this post he left the Institution. This article analyzes the circumstances and proof of a decade where there appears to be evidence of a definite change in his work, more toward Realism, uncomfortable in a system that maintained with difficulty the traditional academic model copy, and incompatible with, in those years was imposed by Spain. At the same time his relation with photography conditioned by the theoretical thoughts of the artist, and his work methods also are analyzed in this article.

The research examines the relationships between three common trust considerations (vendor, Internet and third parties) and attitudes towards online purchasing. The study incorporates privacy and security concerns as a moderating variable and finds that these relationships vary depending on the level of concerns a consumer has when purchasing online. The study suggests that "fears" surrounding the Internet as a place to do business still hinder the use of it for e-commerce purposes, but that the presence of a reputable agent might in some manner mitigate this risk. In the context of business to consumer relationships trust in the vendor is important for the consumer to accept any risk associated with a transaction. Theoretical implications for online customer behavior theory are also discussed. © 2009 Elsevier Inc.

Phagocytosis is a key process of the immune system. The human pathogen Klebsiella pneumoniae is a well known example of a pathogen highly resistant to phagocytosis. A wealth of evidence demonstrates that the capsule polysaccharide (CPS) plays a crucial role in resistance to phagocytosis. The amoeba Dictyostelium discoideum shares with mammalian macrophages the ability to phagocytose and kill bacteria. The fact that K. pneumoniae is ubiquitous in nature and, therefore, should avoid predation by amoebae, poses the question whether K. pneumoniae employs similar means to counteract amoebae and mammalian phagocytes. Here we developed an assay to evaluate K. pneumoniae-D. discoideum interaction. The richness of the growth medium affected the threshold at which the cps mutant was permissive for Dictyostelium and only at lower nutrient concentrations the cps mutant was susceptible to predation by amoebae. Given the critical role of bacterial surface elements on host-pathogen interactions, we explored the possible contribution of the lipopolysaccharide (LPS) and outer membrane proteins (OMPs) to combat phagoyctosis by D. discoideum. We uncover that, in addition to the CPS, the LPS O-polysaccharide and the first core sugar participate in Klebsiella resistance to predation by D. discoideum. K. pneumoniae LPS lipid A decorations are also necessary to avoid predation by amoebae although PagP-dependent palmitoylation plays a more important role than the lipid A modification with aminoarabinose. Mutants lacking OMPs OmpA or OmpK36 were also permissive for D. discoideium growth. Except the LPS O-polysaccharide mutants, all mutants were more susceptible to phagocytosis by mouse alveolar macrophages. Finally, we found a correlation between virulence, using the pneumonia mouse model, and resistance to phagocytosis. Altogether, this work reveals novel K. pneumoniae determinants involved in resistance to phagocytosis and supports the notion that Dictyostelium amoebae might be useful as host model to measure K. pneumoniae virulence and not only phagocytosis. © 2013 March et al.

In this work we examine, for the first time, the molar conductivity behavior of the deeply supercooled room temperature ionic liquid [C4mim][NTf2] in the temperature, pressure and volume thermodynamic space in terms of density scaling (TVγ)−1 combined with the equation of state (EOS). The exponent γσ determined from the Avramov model analysis is compared with the coefficient obtained from the viscosity studies carried out at moderate temperatures. Therefore, the experimental results presented herein provide the answer to the long-standing question regarding the validity of thermodynamic scaling of ionic liquids over a wide temperature range, i.e. from the normal liquid state to the glass transition point. Finally, we investigate the relationship between the dynamic and thermodynamic properties of [C4mim][NTf2] represented by scaling exponent γ and Grüneisen constant γG, respectively.

Influence diagrams are intuitive and concise representations of structured decision problems. When the problem is non-Markovian, an optimal strategy can be exponentially large in the size of the diagram. We can avoid the inherent intractability by constraining the size of admissible strategies, giving rise to limited memory influence diagrams. A valuable question is then how small do strategies need to be to enable efficient optimal planning. Arguably, the smallest strategies one can conceive simply prescribe an action for each time step, without considering past decisions or observations. Previous work has shown that finding such optimal strategies even for polytree-shaped diagrams with ternary variables and a single value node is NP-hard, but the case of binary variables was left open. In this paper we address such a case, by first noting that optimal strategies can be obtained in polynomial time for polytree-shaped diagrams with binary variables and a single value node. We then show that the same problem is NP-hard if the diagram has multiple value nodes. These two results close the fixed-parameter complexity analysis of optimal strategy selection in influence diagrams parametrized by the shape of the diagram, the number of value nodes and the maximum variable cardinality.

Young people in long-term foster care are at risk of experiencing poor social, emotional, behavioural and educational outcomes. Moreover, these placements have a significantly greater chance of breaking down compared to those involving children. This article critically evaluates the factors associated with this particular outcome. It was carried out through a literature review conducted by a social work practitioner in one Health and Social Care Trust in Northern Ireland. The findings evidenced that, apart from overriding safety concerns, placement breakdown was not a one-off event but rather a complex process involving the interplay between a range of dynamic risk and protective factors over time, operating in the wider context of the young person’s history and life experiences. The significance of these findings for social work practitioners is finally considered by identifying key theories to inform understanding and intervention.

This article draws on an institutional ethnographic inquiry into the work of paramedics and the institutional setting that organizes and coordinates their work processes. Drawing on over 200 hours of observations and over 100 interviews with paramedics (average length of 18 minutes) and other emergency medical personnel, this article explores the standard and not so standard work of paramedics as they assess and care for their patients on the front lines of emergency health services. More specifically, I focus on the multiplicity of interfacing social, demographic, locational, situational, and institutional factors that shape and organize the work of paramedics. In doing so, this article provides insights into how paramedics orient to the social context in which their work occurs and contrasts this actual work with how their work is institutionally reported and made visible; what gets counted institutionally is not necessarily the same as what counts for the paramedics. This article problematizes this demarcation between what is known institutionally and “systematic practices of ‘not knowing’” (DeVault, 2008, p. 290).

This article is based on an institutional ethnographic inquiry into the work of paramedics and the institutional setting that organizes and coordinates their work processes in a major City in Canada. Drawing on over 200 hours of observations and over 100 interviews with paramedics (average length of 18 minutes) and other emergency medical personnel, this article explores the standard and not so standard work of paramedics as they assess and care for their patients on the front lines of emergency health services. The multiplicity of interfacing social, demographic, locational, and situational factors that shape and organize the work of paramedics are analyzed. In doing so, this article provides insights into the complex work of an understudied yet ever-important profession in healthcare.

The personalisation agenda is a government initiative aimed at transforming adult social care through giving service users choice and control over the care they receive. A key part of this agenda is the provision of direct payments; cash payments made to individuals eligible for social care services which allow them to manage their own care. Research suggests that direct payments can enable people with dementia to stay in their own home for longer and experience greater choice, flexibility and an improved social life. However very few people with dementia currently access direct payments. The objective of this research was to explore the social care experiences of people with dementia in relation to their access to and use of direct payments. 26 semi-structured interviews were conducted with people with dementia in receipt of social care services in the community, and their carers and social workers, and focus groups held with two community social work teams. It was found that direct payments tended to be seen as a fall-back option, for example as the only alternative to residential care, or as a solution to problems with traditional services. Direct payments appeared to afford particular benefits to people with dementia in terms of flexibility, continuity of care and access to local facilities. It is therefore important that this group are enabled to access direct payments. The second (ongoing) phase of this research comprises the design and pilot testing of an intervention aimed at improving access to direct payments by people with dementia.

In this article we intend to make a summary overview of the influence that literary production, originated under colonial mapping missions or later in travel writing, had in the construction and establishment of a discourse to advertise and promote tourism in Mauritania. To this end we will draw on travel narratives that are illustrative of different periods and that correspond in some way to discourses of otherness. In this specific case, such discourses relate to the “Moors” of the West African coast and were produced in various historical contexts. We will also consider the discourse present in the tourism promotion materials of the colonial period and we will demonstrate to what extent it can be engaged in a dialogue with 19th and 20th centuries’ Western colonial literature.

One hundred and thirty four subjects participated in this survey. Quantitative data were obtained and correlational analyses were used to test a model to study the relationships among the achievement of work values and organizational commitment and job satisfaction and to identify the moderating effects of the meaningfulness of work and responsibility for work on these relationships. Part-time faculty in the Faculty of Continuing Education of a community college were mailed a questionnaire on all the variables of the model. Several reliable, valid instruments were used to test the variables. Data analysis through Pearson correlation and stepwise multiple regression analyses revealed that the achievement of the work values of recognition and satisfaction with promotions did predict organizational commitment and job satisfaction, although the moderating effects of the meaningfulness of work and responsibility for work was not supported in this study. This study suggests that the revised model may be used for determining the relationships between the achievement of work values and organizational commitment and job satisfaction in a community college setting.
