Contact as a Policy Mechanisim in Integrated schools in Israel and Northern Ireland

Policy initiatives in inter-group education evolved in Northern Ireland and Israel at around the same
time. In each jurisdiction, the emphasis is on improving relations between protagonist groups in
ethnically divided societies. Central to this objective and at the core of integrated education
(Northern Ireland) and bilingual/bi-national education (Israel) is sustained contact in a shared
learning environment. Based on qualitative research in four schools, this paper examines the nature
of the contact experience in two integrated schools in Northern Ireland and two bilingual/binational
schools in Israel. Through comparative analysis, and with reference to contact theory, it
illuminates some of the contextual and process variables that seemingly mediate the quality and
moderate the effectiveness of contact in each school setting.

Accessing Social Work Case Files for Research Purposes: Some Issues and Problems

The use of social work case files as an important research resource is being threatened by the increasing regulation of both the research process and access to personal identifiable information. While these developments can be seen as a reaction to specific incidents of inappropriate research and the misuse of personal information, it is argued that the pendulum has swung too far the other way, and in seeking to protect the rights of vulnerable individuals, the lives of these same individuals may go unstudied with the consequence that they receive less appropriate services. Drawing upon the current research of the authors, this article explores the difficulties encountered in gaining access to social work case files for research purposes without the explicit consent of service users and highlights the uncertainty surrounding this issue. Suggestions are made for improvements in the situation.

Comparison of mass transfer effects in the heterogeneously catalysed hydrogenation of phenyl acetylene in heptane and an ionic liquid

The selective heterogeneous catalytic reduction of phenyl acetylene to styrene over palladium supported on calcium carbonate is reported in both an ionic liquid and a molecular solvent. By using a rotating disc reactor in conjunction with results from a stirred tank reactor it is possible, for the first time, to disentangle the mass transfer contributions in the ionic liquid system. For both heptane and 1-butyl-3-methyl imidazolium bis{(trifluoromethyl)sulfonyl}imide, the reaction in the rotating disc reactor is dominated by reaction in the entrained film on the disc compared with very limited reaction in the bulk liquid. The lower reaction rate obtained in the ionic liquid compared with the organic solvent is shown to be due to the slow transport of the hydrogen dissolved in the liquid. It is clear from the results presented herein that, although the hydrodynamics of similar reactors used for biological treatment of wastewater are well understood, on using a more viscous fluid and higher rotation speeds necessary for fine chemical catalysis these simple relationships breakdown.

The training in social and solidarity economy. Analysis of the university offer in Spain

This research analyses the importance of the training for the promotion of the social economy in two ways: 1) focusing on the characteristics of the educational offer of Social Economy and 2) analyzing its differences regarding to those studies from the Management, entrepreneurship, and innovations areas. To this aim, it is carried out as a first step a literature review of the contributions that study the relationships that can exist between the education and Economy. Then, being based on this previous analysis, we already center our research on the Social Economy sector and its relations with the education system. To get this objective, it has been developed a database that includes all the postgraduate titles related to the Economics area. Likewise, a questionnaire has been designed with the aim of characterize the training in social Economy. As a conclusion, it is obtained that the training in social economy in postgraduate studies in the Spanish Universities is very poor. On the other hand, there are significant differences between Social Economy degrees and Business Management, entrepreneurship and innovation degrees with regard to different aspects such as: values to transmit, competencies, skills, the way of understanding the Economy, etc. Based on these conclusions, different recommendations are proposed in order to promote and boost this other way of doing Economy through the training and education in postgraduate studies.

Cytoplasmic Irradiation Induces Mitochondrial-Dependent 53BP1 Protein Relocalization in Irradiated and Bystander Cells

The accepted paradigm for radiation effects is that direct DNA damage via energy deposition is required to trigger the downstream biological consequences. The radiation-induced bystander effect is the ability of directly irradiated cells to interact with their nonirradiated neighbors, which can then show responses similar to those of the targeted cells. p53 binding protein 1 (53BP1) forms foci at DNA double-strand break sites and is an important sensor of DNA damage. This study used an ionizing radiation microbeam approach that allowed us to irradiate specifically the nucleus or cytoplasm of a cell and quantify response in irradiated and bystander cells by studying ionizing radiation-induced foci (IRIF) formation of 53BP1 protein. Our results show that targeting only the cytoplasm of a cell is capable of eliciting 53BP1 foci in both hit and bystander cells, independently of the dose or the number of cells targeted. Therefore, direct DNA damage is not required to trigger 53BP1 IRIF. The use of common reactive oxygen species and reactive nitrogen species (RNS) inhibitors prevent the formation of 53BP1 foci in hit and bystander cells. Treatment with filipin to disrupt membrane-dependent signaling does not prevent the cytoplasmic irradiation-induced 53BP1 foci in the irradiated cells, but it does prevent signaling to bystander cells. Active mitochondrial function is required for these responses because pseudo-rho(0) cells, which lack mitochondrial DNA, could not produce a bystander signal, although they could respond to a signal from normal rho(+) cells.

Use and access to ICT in students of public secondary schools in Chihuahua City, Mexico: inclusion in teaching and digital literacy

This paper addresses the issue of the digital divide in students of public secondary schools at Chihuahua City, Mexico. It seeks to identify potential inequality of opportunities with regards to subjects’ access to information, knowledge and education through the ICT (internet, mobile telephony, broadband and television). The study takes three schools as investigative stage, using the survey as a data collection instrument, identifying patterns of behavior regarding: general knowledge of them, access to computer equipment and internet, and characterization of their use. Other aspects of analysis are the identification of the educational level of parents and access to technology resources available for academic and non-academic purposes in various application areas (home, school and social environment). The proposal concludes, that it is through the recollection of alternatives suggested by the teachers themselves to incorporate ICT for teaching purposes in a systematic and planned fashion, whose greatest reflection manifests in better digital literacy indicators.

Differences in Abdominal and Liver Fat Accumulation Between Obesity-Matched Adults With and Without Type 2 Diabetes

Despite attempts to identify the mechanisms by which obesity leads to the development of Type 2 Diabetes (T2D), it remains unclear why some but not all adults with obesity develop T2D. Given the established associations between visceral adipose tissue (VAT) and liver fat with insulin resistance, we hypothesized that compared to age and obesity matched adults who were non-diabetic (NT2D), adults with T2D would have greater amounts of VAT and liver fat. The International Study of Prediction of Intra-Abdominal Adiposity and Its Relationship with Cardiometabolic Risk/Intra-Abdominal Adiposity (INSPIRE ME IAA) aims to study the associations between VAT and liver fat and risk of developing T2D and cardiovascular disease. Four thousand, five hundred and four participants were initially recruited; from this, 2383 White and Asian adults were selected for this ancillary analysis. The NT2D and T2D groups were matched for age, body mass index (BMI) and waist circumference (WC). The T2D and NT2D groups were also compared to participants with either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT; IFG/IGT)). Abdominal adipose tissue was measured by computed tomography; liver fat was estimated using computed tomography-derived mean attenuation. Secondary analysis determined whether differences existed between NT2D and T2D groups in VAT and liver fat accumulation within selected BMI categories for Whites and Asians. We report across sex and race, T2D and IFG/IGT groups had elevated VAT and liver fat compared to the NT2D group (p<0.05). VAT was not different between IFG/IGT and T2D groups (p>0.05), however liver fat was greater in the T2D group compared to the IFG/IGT group in both Whites and Asians (p<0.05). Within each BMI category, the T2D group had elevated VAT and liver fat compared to the age and anthropometrically matched NT2D group in both Whites and Asians (p<0.05). With few exceptions, abdominal subcutaneous adipose tissue was not different in the T2D or IFG/IGT groups compared to the NT2D group independent of sex and race. Compared to age and obesity-matched adults who are NT2D, we observe that White and Asian adults with T2D, and those with IFG/IGT, present with greater levels of both VAT and liver fat.
