Methyl 4-phenyl-1,2,3,3a,4,4a,5,12c-octahydronaphtho[1′,2′:3,2]furo[5,4-b]pyrrolizine-4a-carboxylate
In the title compound, C26H25NO3, both pyrrolidine rings adopt envelope conformations, whereas the dihydropyran ring adopts a half-chair conformation. The phenyl ring is oriented at an angle of 27.9 (1)° with respect to the naphthalene ring system. An intramolecular C—H⋯O hydrogen bond is observed. The crystal packing is stabilized by weak intermolecular C—H⋯π interactions
Language policy and orthographic harmonization across linguistic, ethnic and national boundaries in Southern Africa
Drawing on online and daily newspapers, speakers' language and
writing practices, official government documents and prescribed spelling systems in
Southern Africa, the paper explores the challenges and possibilities of orthographic
reforms allowing for mobility across language clusters, ethnicity, regional and
national borders. I argue that this entails a different theorisation of language, and for
orthographies that account for the translocations and diasporic nature of late modern
African identities and lifestyles. I suggest an ideological shift from prescriptivism to
practice-orientated approaches to harmonisation in which orthographies are based
on descriptions of observable writing practices in the mobile linguistic universe.
The argument for orthographic reforms is counterbalanced with an expose on
current language policies which appear designed for an increasing rare monoglot
'standard' speaker, who speaks only a 'tribal' language. The implications of the
philosophical challenges this poses for linguists, language planners and policy
makers are thereafter discussed.IS
The social cognition of medical knowledge, with special reference to childhood epilepsy
This paper arose out of an engagement in medical communication courses at a Gulf university. It deploys a theoretical framework derived from a (critical) sociocognitive approach to discourse analysis in order to investigate three aspects of medical discourse relating to childhood epilepsy: the cognitive processes that are entailed in relating different types of medical knowledge to their communicative context; the types of medical knowledge that are constituted in the three different text types analysed; and the relationship between these different types of medical knowledge and the discursive features of each text type. The paper argues that there is a cognitive dimension to the human experience of understanding and talking about one specialized from of medical knowledge. It recommends that texts be studied in medical communication courses not just in terms of their discrete formal features but also critically, in terms of the knowledge which they produce, transmit and reproduce
Effects of cash transfers on Children's health and social protection in Sub-Saharan Africa: differences in outcomes based on orphan status and household assets
BACKGROUND: Unconditional and conditional cash transfer programmes (UCT and CCT) show potential to improve the well-being of orphans and other children made vulnerable by HIV/AIDS (OVC). We address the gap in current understanding about the extent to which household-based cash transfers differentially impact individual children’s outcomes, according to risk or protective factors such as orphan status and household assets. METHODS: Data were obtained from a cluster-randomised controlled trial in eastern Zimbabwe, with random assignment to three study arms – UCT, CCT or control. The sample included 5,331 children ages 6-17 from 1,697 households. Generalized linear mixed models were specified to predict OVC health vulnerability (child chronic illness and disability) and social protection (birth registration and 90% school attendance). Models included child-level risk factors (age, orphan status); household risk factors (adults with chronic illnesses and disabilities, greater household size); and household protective factors (including asset-holding). Interactions were systematically tested. RESULTS: Orphan status was associated with decreased likelihood for birth registration, and paternal orphans and children for whom both parents’ survival status was unknown were less likely to attend school. In the UCT arm, paternal orphans fared better in likelihood of birth registration compared with non-paternal orphans. Effects of study arms on outcomes were not moderated by any other risk or protective factors. High household asset-holding was associated with decreased likelihood of child’s chronic illness and increased birth registration and school attendance, but household assets did not moderate the effects of cash transfers on risk or protective factors. CONCLUSION: Orphaned children are at higher risk for poor social protection outcomes even when cared for in family-based settings. UCT and CCT each produced direct effects on children’s social protection which are not moderated by other child- and household-level risk factors, but orphans are less likely to attend school or obtain birth registration. The effects of UCT and CCT are not moderated by asset-holding, but greater household assets predict greater social protection outcomes. Intervention efforts need to focus on ameliorating the additional risk burden carried by orphaned children. These efforts might include caregiver education, and additional incentives based on efforts made specifically for orphaned children
Epistemological access through lecture materials in multiple modes and language varieties: the role of ideologies and multilingual literacy practices in student evaluations of such materials at a South African University
This paper seeks to address the ways in which ideology and literacy practices shape the responses of students to an ongoing initiative at the University of the Western Cape aimed at diversifying options for epistemological access, specifically the language varieties and the modes in which parts of the curriculum for a third year linguistics module are delivered. Students’ responses to the materials in English and in two varieties of Afrikaans and isiXhosa (as mediated in writing vs orally) are determined, and used as basis to problematize decisions on language variety and mode in language diversification initiatives in Higher Education in South Africa. The findings of the paper are juxtaposed against particular group interests in the educational use of a language as well as differences in the affordances and impact of different modes of language use. The paper suggests that beyond the euphoria of using languages other than English in South African Higher Education, several issues (such as entrenched language practices, beliefs and language management orientations) require attention if the goals of transformation in this sector are to be attained
Global Englishes language teaching:Bottom-up curriculum implementation
In today's globalised world, the needs of English language learners have changed, particularly those learning to use the English language as a lingua franca. Growing research showcasing the global use of English as a lingua franca (ELF), the creativity of ELF users, and the diverse ways in which they negotiate successful communication in multilingual encounters has numerous implications for the field of TESOL. This article reports on a study with preservice and in‐service TESOL practitioners taking a Global Englishes for Language Teaching (GELT) option course in a 1‐year Master's in TESOL programme at a Russell Group university in the United Kingdom. The study explores attitudes towards GELT but also towards the proposals for, and barriers to, curriculum innovation as well as factors influencing such attitudes. Interviews (n = 21) and questionnaires (n = 47) revealed that attitudes remain norm bound, yet the study revealed a positive orientation towards GELT and provided insights into the feasibility of GELT‐related curriculum innovation and teacher education syllabus design. The study calls for more research with preservice and in‐service TESOL practitioners at different stages of the innovation process to ensure successful and sustainable GELT curricular innovation
Macro-language planning for multilingual education : focus on programmes and provision
This overview identifies some common features of macro-level language planning and briefly summarises the changing approaches to the analysis of macro-planning in the field. It previews six cases of language-in-education planning in response to linguistic diversity presented by the contributors to this issue. The cases show how macro-planning can either fail to recognise diverse ethnolinguistic identities or work to acknowledge them. Three common themes in language planning for multilingual education can be identified from the contributions: (i) top-down definitions of what counts as mother tongue can have both intended and unintended outcomes; (ii) language-as-problem responses to linguistic diversity can work to reinforce social exclusion; and (iii) the acknowledgement of diversity and minority language rights needs to flow through from statements of intent to on-the-ground implementation if they are to become a reality
"Then you get a teacher" - Guidelines for excellence in teaching
Background: Current literature calls for the explicit teaching to health-science educators of the skills, knowledge and dispositions
that are required for successful teaching in higher education.
Aims: This paper draws on evidence from an Oral Hygiene department at a South African university in order to
illustrate these teaching-competency needs. Insights from the evidence are synthesised with current literature regarding best
teaching practice, in support of an appropriate framework for the development of teaching competencies to health-science
educators.
Description: A qualitative approach, using a case study, was adopted. The cohort comprised fifteen students in the first-year Oral
Hygiene cohort class and the ten educators who taught their programme. Data was collected through semistructured interviews
and open-ended questionnaires. The topics that emerged from the combined analysis of the interviews and the questionnaires
were organised into a grid so that common themes could be identified. Current literature regarding teaching and learning was used
as a framework for interpreting the empirical evidence, from which three categories emerged. The first category included
suggestions from students regarding what to do to teach better. A review of the literature indicates that these competencies can be
effectively learnt from self-help guides. The second category included requests for skills development. Literature review suggests
that these might effectively be learnt from single-event workshops facilitated by more able peers. Responses in the final category
highlighted the need for an underpinning theory of teaching and learning, and signalled the need for a more theoretically
grounded and detailed approach to teacher development.
Conclusion: The framework developed from the empirical study and current literature makes it possible for individual clinical
teachers, and staff developers, to construct teaching-competency development plans that are pertinent to individual teachers’
needs, relevant and practical, educationally sound, and cost-effective in terms of time and effort
