Crossing borders through cyberspace: a discussion of a social work education electronic exchange pilot project across the Atlantic

This article discusses a trial electronic exchange project developed between social work education departments in the Republic of Ireland and the USA. It outlines the contemporary significance and challenges of integrating global content into national social work curricula, which are often strongly tied to statutory or accreditation requirements. The mechanics of the exchange are explained and critiqued in detail. An illustrative example of how the transnational students discussed two questions is analyzed. The article finds that an international electronic exchange has great potential to make global social work real to students by allowing them to cross borders through cyberspace, however it requires careful planning and attention to cultural and educational system differences.

In vitro testing of Advanced JAX (TM) Bone Void Filler System: species differences in the response of bone marrow stromal cells to beta tri-calcium phosphate and carboxymethylcellulose gel

The Advanced JAX (TM) Bone Void Filler System (AJBVFS) is a novel bone graft material manufactured by Smith and Nephew Orthopaedics Ltd. and comprises beta tri-calcium phosphate granules with carboxymethylcellulose (CMC) gel as a handling agent. This study investigated the potential, in vitro, of the AJBVFS to function as a delivery system for cell therapy to enhance healing of bone defects. The attachment of rabbit bone marrow stromal cells (rbBMSCs), human BMSCs (hBMSCs) and human bone-derived cells (hBDCs) to JAX (TM) granules and the effect of CMC gel on cell proliferation and differentiation were investigated. There were slight species differences in the number and morphology of cells attached on the JAX (TM) granules with less rbBMSC attachment than human. All cells tolerated the presence of CMC gel and a reduction in cell number was only seen after longer exposure to higher gel concentrations. Low concentrations of CMC gel enhanced proliferation, alkaline phosphatase (ALP) expression and ALP activity in human cells but had no effect on rbBMSC. This study suggests that AJBVFS is an appropriate scaffold for the delivery of osteogenic cells and the addition of CMC gel as a handling agent promotes osteogenic proliferation and differentiation and is therefore likely to encourage bone healing.

Testosterone levels in dominant sociable males are lower than in solitary roamers: Physiological differences between three male reproductive tactics in a sociably flexible mammal

The relative plasticity hypothesis predicts that alternative tactics are associated with changes in steroid hormone levels. In species with alternative male reproductive tactics, the highest androgen levels have usually been reported in dominant males. However, in sociable species, dominant males show amicable behaviors to gain access to females, which might conflict with high testosterone levels. We compared testosterone, corticosterone, and resting metabolic rate in male striped mice (Rhabdomys pumilio) following a conditional strategy with three different reproductive tactics: (i) philopatric group-living males, (ii) solitary-living roamers, (iii) dominant but sociable group-living territorial breeders. Philopatrics had the lowest testosterone but highest corticosterone levels, suggesting that they make the best of a bad job. Dominant territorial breeders had lower testosterone levels than roamers, which have a lower competitive status. Roamers had the highest testosterone levels, which might promote risky behavior, such as invading territories defended by territorial males. Roamers also had lower resting metabolic rates than either type of group-living males. Our results suggest that dominant males' testosterone levels reflect a trade-off between low testosterone amicable behavior and high testosterone dominance behavior.

Developing outcomes for educational services: a children's rights-based approach

This article provides a rationale for and insight into an explicit children's rights-based approach to the identification of outcomes for proposed educational interventions. It presents a critical reflection on a research project which sought to integrate international children's rights standards into the design of services through a children's rights audit of potential outcomes and the meaningful engagement of children in the research and service design processes. While children are involved increasingly as co-researchers in qualitative studies, it is less common for this to occur in quantitative studies. This article offers some additional insight into children's participation in the interpretation of data from a large-scale baseline survey. The article concludes with an argument that international children's rights law provides not just a legal imperative but also a comprehensive framework with which to assert the case for increased recognition of children as salient stakeholders in all aspects of service design.

An Educational Initative in Anaesthetic Nursing Practice

The National Board for Nurses, Midwives and Health Visitors in Northern Ireland (NBNI) has adopted the principles of the UKCC's recommendations for specialist nursing practice and Incorporated these within their continuing education framework. Stage two of this framework decrees the standard required for specialist nursing practice (NBNI, 1995) and, as a result, a specialist anaesthetic nursing course has been instigated. The course extends over 44 weeks and includes 8 weeks of consolidation practice, comprising seven modules at degree and diploma level. The course gives the students an opportunity to deepen their knowledge, skills and attitudes in the field of anaesthetic nursing. Nurses were taught the necessary skills to work in collaboration with other professionals, patients and families in order to coordinate a patient-centred approach to perianaesthetic care. The role of the anaesthetic nurse specialist should be viewed as complementary to that of the anaesthetist. This course facilitates and encourages practitioners to move beyond registered practice on qualifying to a more specialized role where care is delivered in an innovative and creative manner.

Differences in mouse models of diabetes mellitus in studies of male reproduction

Diabetes Mellitus (DM) has been found to have subtle yet profound effects on the metabolic status of the testis, the expression of numerous spermatogenic genes and is associated with increased numbers of sperm with nuclear DNA damage. The precise mechanism causing these detrimental effects remains unknown. The presence of increased levels of the most prominent member (carboxymethyllysine - CML) of the advanced glycation end product adducts and their receptor (RAGE) in the reproductive tract of DM men has provided a new avenue for research. As there are suspicions that the antibiotic (streptozotocin - STZ) employed to induce DM is also capable of causing oxidative stress and DNA damage, we compared CML and RAGE levels in the reproductive tract and sperm nDNA status of STZ mice with the levels in the Ins(2Akita) mouse to determine which more closely mimics the situation described in the human diabetic. CML was observed in the testes, epididymes and sperm of all animals. Sperm from DM mice showed particularly strong CML immunolocalization in the acrosomal cap, the equatorial region and whenever present, cytoplasmic droplets. Although increased, the level of CML on the sperm of the STZ and Ins(2Akita) DM mice did not reach statistical significance. RAGE was present on the developing acrosome and epididymal sperm of all animals and in discrete regions of the epididymes of the DM models. Only the epididymal sperm of the Ins(2Akita) mice were found to have significantly increased (p < 0.0001) nDNA damage. The Ins(2Akita) mouse therefore appears to more accurately reflect the conditions found in the human and, as such, is a more representative model for the study of diabetes and glycation's influence on male fertility.

Transcending cultural differences: the role of language in migrants' integration

This research seeks to contribute to current debates on migration by examining the role of language in the process of migrants’ integration. It will consider how migrant workers living in an area with little history of international immigration navigate their way within a new destination to cope with language difference. The paper is based on empirical research (interviews and focus groups) conducted in Northern Ireland, an English speaking region with a small proportion of Irish-English bilinguals (10.3 percent of population had some knowledge of Irish in the 2001 Census). Much of the research to date, while acknowledging the importance of culture and language for migrants’ positive integration, has only begun to unpack the way in which cultural difference such as language is dealt with at an individual, family or societal level. Several themes emerge from the research including the significance of social and civil structures and the role of individual agents as new culture is created through the celebration of difference.

Alternative Factor Models and Heritability of the Short Leyton Obsessional Inventory-Children's Version

An alternative models framework was used to test three confirmatory factor analytic models for the Short Leyton Obsessional Inventory-Children's Version (Short LOI-CV) in a general population sample of 517 young adolescent twins (11-16 years). A one-factor model as implicit in current classification systems of Obsessive-Compulsive Disorder (OCD), a two-factor obsessions and compulsions model, and a multidimensional model corresponding to the three proposed subscales of the Short LOI-CV (labelled Obsessions/Incompleteness, Numbers/Luck and Cleanliness) were considered. The three-factor model was the only model to provide an adequate explanation of the data. Twin analyses suggested significant quantitative sex differences in heritability for both the Obsessions/Incompleteness and Numbers/Luck dimensions with these being significantly heritable in males only (heritability of 60% and 65% respectively). The correlation between the additive genetic effects for these two dimensions in males was 0.95 suggesting they largely share the same genetic risk factors.

Health-related quality of life and children’s happiness with their childcare

Background Almost without exception, research into the range and quality of childcare provision, and its correlates with children’s development, comes from the perspective of adults. Parents, childcare workers, teachers and the general public have all been asked for their views on childcare. In contrast, there is a dearth of information on attitudes to childcare provision and its correlates from the perspective of the children themselves.

Methods A total of 3657 Primary 7 children, who are 10 or 11 years of age, completed the KIDSCREEN-27 health-related quality of life (HRQoL) measure along with questions on their childcare provision as part of an online survey carried out in schools.

Results Most children receiving childcare from people other than their parents were completely happy with their care. Childcare was related to poorer HRQoL for girls on four of the ?ve KIDSCREEN domains, although the effect sizes were small. For both boys and girls, there were statistically signi?cant, although modest, correlations between happiness with childcare and scores on all ?ve domains of the KIDSCREEN-27.

Conclusions Overall, the ?ndings suggest that most children are happy with their care and that any differences between the HRQoL of those who are cared for by their parents and those who are not are small to moderate.

Synovial membrane immunohistology in early untreated juvenile idiopathic arthritis: differences between clinical subgroups

Abstract: Objective Juvenile idiopathic arthritis (JIA) consists of a heterogeneous group of inflammatory disorders, within which there are a number of clinical subgroups. Diagnosis and assignment to a particular subgroup can be problematical and more concise methods of subgroup classification are required. This study of the synovial membrane characterises the immunohistochemical features in early untreated, newly diagnosed JIA and compares findings with disease subgroup at 2 years.

Methods: 42 patients with newly diagnosed untreated JIA underwent synovial biopsy before the administration of steroids or disease-modifying antirheumatic drugs. Patients were classified as either polyarticular, persistent oligoarticular or extended-to-be oligoarticular. The location and semiquantitative analysis of T-cell subsets, B cells, macrophages and blood vessels were determined using immunohistochemistry.

Results: Synovial hyperplasia varied significantly between the three groups
(p<0.0001). There was a significant difference in the CD3 T-cell population between the three groups (p=0.004) and between the extended-to-be and persistent group (p=0.032). CD4 expression was significantly higher in the poly and extended-to-be oligo groups (p=0.002), again the extended-to-be group had more CD4 T cells than the persistent group (p=0.008). B-cell infiltrates were more marked in the polyarticular group and were significantly higher in the extended-to-be group compared with the persistent group (p=0.005). Vascularisation was more pronounced in the polyarticular and extended-to-be oligoarticular groups, the extended-to-be group had significantly more vascularisation than the persistent group (p=0.0002).

Conclusions: There are significant differences in the histomorphometric features of synovial tissue between patient subgroups. Immunohistological examination of synovial membrane biopsies may provide further insight into early disease processes in JIA.
