Intersectional impact of multiple identities on social work education in the UK

This document is the Accepted Manuscript version of the following article: Ben Chi-pun Liu, ‘Intersectional impact of multiple identities on social work education in the UK’, Journal of Social Work, Vol 17(2): 226-242, March 2017. © 2016 The Author(s).

Reprinted by permission of SAGE Publications.Summary: The study reviews the records of 671 social work students and graduates including the seven intakes from the first cohort in 2003/2004 to the intake in 2010/2011 to examine the interacting effect of learning difficulties, ethnicity and gender on the completion of social work training at a university in the South East of England. Findings: Among the students, 79.9% of them were female, 50.1% were black, 27.9% white, 10.7% Asian and 11.3% other ethnicities. A majority of students did not report any disability. Among those who did (n ¼ 84), 52.3% (n ¼ 44) reported a learning difficulty.The percentage of students who have successfully completed the training is 76.4%, a completion rate that is comparable to the UK’s national figure. Having controlled the confounding variables, hierarchical logistic regression identified the risk factor for dropoutfrom undergraduate social work programme as black female students with learning difficulties (odds ratio ¼ 0.100, 95% confidence interval ¼ 0.012–0.862, p < 0.05). Findings suggested that students with multiplicity of identities, i.e. being black and female and with a learning difficulty, have a lower probability to complete the programme successfully. Applications: Strategies for tackling the intersecting disadvantages of race, gender and disabilities in social work training should embrace three principles: providing continuous support, focusing on how the support is provided and addressing contextual and structural barriers.Peer reviewedFinal Accepted Versio

Social work and gender::An argument for practical accounts

This article contributes to the debate on gender and social work by examining dominant approaches within the field. Anti-discriminatory, woman-centered and intersectional accounts are critiqued for reliance upon both reification and isolation of gender. Via examination of poststructural, queer and trans theories within social work, the author then presents accounts based upon structural/materialist, ethnomethodological and discursive theories, in order to open up debates about conceptualization of gender. These are used to suggest that social work should adopt a focus on gender as a practical accomplishment that occurs within various settings or contexts

Assessing the Role of CD103 in Immunity to an Intestinal Helminth Parasite

In the intestine, the integrin CD103 is expressed on a subset of T regulatory (T(reg)) cells and a population of dendritic cells (DCs) that produce retinoic acid and promote immune homeostasis. However, the role of CD103 during intestinal helminth infection has not been tested.We demonstrate that CD103 is dispensable for the development of protective immunity to the helminth parasite Trichuris muris. While we observed an increase in the frequency of CD103(+) DCs in the lamina propria (LP) following acute high-dose infection with Trichuris, lack of CD103 had no effect on the frequency of CD11c(+) DCs in the LP or mesenteric lymph nodes (mLN). CD103-deficient (CD103(-/-)) mice develop a slightly increased and earlier T cell response but resolve infection with similar kinetics to control mice. Similarly, low-dose chronic infection of CD103(-/-) mice with Trichuris resulted in no significant difference in immunity or parasite burden. Absence of CD103 also had no effect on the frequency of CD4(+)CD25(+)Foxp3(+) T(reg) cells in the mLN or LP.These results suggest that CD103 is dispensable for intestinal immunity during helminth infection. Furthermore, lack of CD103 had no effect on DC or T(reg) recruitment or retention within the large intestine

NADPH oxidase-mediated redox signal contributes to lipoteichoic acid-induced MMP-9 upregulation in brain astrocytes

<p>Abstract</p> <p>Background</p> <p>Lipoteichoic acid (LTA) is a component of gram-positive bacterial cell walls and may be elevated in the cerebrospinal fluid of patients suffering from meningitis. Among matrix metalloproteinases (MMPs), MMP-9 has been observed in patients with brain inflammatory diseases and may contribute to the pathology of brain diseases. Moreover, several studies have suggested that increased oxidative stress is implicated in the pathogenesis of brain inflammation and injury. However, the molecular mechanisms underlying LTA-induced redox signal and MMP-9 expression in brain astrocytes remain unclear.</p> <p>Objective</p> <p>Herein we explored whether LTA-induced MMP-9 expression was mediated through redox signals in rat brain astrocytes (RBA-1 cells).</p> <p>Methods</p> <p>Upregulation of MMP-9 by LTA was evaluated by zymographic and RT-PCR analyses. Next, the MMP-9 regulatory pathways were investigated by pretreatment with pharmacological inhibitors or transfection with small interfering RNAs (siRNAs), Western blotting, and chromatin immunoprecipitation (ChIP)-PCR and promoter activity reporter assays. Moreover, we determined the cell functional changes by migration assay.</p> <p>Results</p> <p>These results showed that LTA induced MMP-9 expression via a PKC(α)-dependent pathway. We further demonstrated that PKCα stimulated p47^phox/NADPH oxidase 2 (Nox2)-dependent reactive oxygen species (ROS) generation and then activated the ATF2/AP-1 signals. The activated-ATF2 bound to the AP-1-binding site of MMP-9 promoter, and thereby turned on MMP-9 gene transcription. Additionally, the co-activator p300 also contributed to these responses. Functionally, LTA-induced MMP-9 expression enhanced astrocytic migration.</p> <p>Conclusion</p> <p>These results demonstrated that in RBA-1 cells, activation of ATF2/AP-1 by the PKC(α)-mediated Nox(2)/ROS signals is essential for upregulation of MMP-9 and cell migration enhanced by LTA.</p

Cross-cutting principles for planetary health education

Since the 2015 launch of the Rockefeller Foundation Lancet Commission on planetary health,1 an enormous groundswell of interest in planetary health education has emerged across many disciplines, institutions, and geographical regions. Advancing these global efforts in planetary health education will equip the next generation of scholars to address crucial questions in this emerging field and support the development of a community of practice. To provide a foundation for the growing interest and efforts in this field, the Planetary Health Alliance has facilitated the first attempt to create a set of principles for planetary health education that intersect education at all levels, across all scales, and in all regions of the world—ie, a set of cross-cutting principles
