Students who have sex with teachers : a youth perspective from the Western Cape education region

This thesis begins to explore the phenomenon, in the South African education system, of students who have sex with teachers. The study provides a more nuanced understanding of student-teacher sexual relationships, reporting on empirical research which explores the prevalence of the phenomenon, the circumstances in which it occurs and students' opinions. In doing so, this research contributes to a more complete picture of student-teacher sexual relationships, exploring a plurality of viewpoints, in order to inform policy and interventions

Draft crystal structure of the vault shell at 9-A resolution.

Vaults are the largest known cytoplasmic ribonucleoprotein structures and may function in innate immunity. The vault shell self-assembles from 96 copies of major vault protein and encapsulates two other proteins and a small RNA. We crystallized rat liver vaults and several recombinant vaults, all among the largest non-icosahedral particles to have been crystallized. The best crystals thus far were formed from empty vaults built from a cysteine-tag construct of major vault protein (termed cpMVP vaults), diffracting to about 9-A resolution. The asymmetric unit contains a half vault of molecular mass 4.65 MDa. X-ray phasing was initiated by molecular replacement, using density from cryo-electron microscopy (cryo-EM). Phases were improved by density modification, including concentric 24- and 48-fold rotational symmetry averaging. From this, the continuous cryo-EM electron density separated into domain-like blocks. A draft atomic model of cpMVP was fit to this improved density from 15 domain models. Three domains were adapted from a nuclear magnetic resonance substructure. Nine domain models originated in ab initio tertiary structure prediction. Three C-terminal domains were built by fitting poly-alanine to the electron density. Locations of loops in this model provide sites to test vault functions and to exploit vaults as nanocapsules

How older people living with HIV narrate their quality of life: Tensions with quantitative approaches to quality-of-life research

This article draws on life-history interviews with older (aged 50+) people living with HIV in England to uncover the interpretive practices in which they engaged as they evaluated their own quality of life (QoL). Our paper highlights the distinctive insights that biographical and narrative approaches can bring to QoL research. While accounts of subjectively ‘poor’ QoL were relatively straightforward and unequivocally phrased, accounts of subjectively ‘good’ and ‘OK’ QoL were produced using complex interpretive and evaluative practices. These practices involved biographical reflection and contextualization, with participants weighing up and comparing their current lives’ ‘pros’ and ‘cons’, their own lives with the lives of others, and their present lives with lives they had imagined having at the time of interview. Thus, ‘good’ and ‘OK’ QoL were constructed using practical, relational, and interpretive work – features of QoL analytically unavailable in quantitative data gathered through standardised measures (including our own survey data collected from these same participants). Our findings underscore the uneasy fit between QoL’s quantitative measurement and its subjective understandings and evaluations, on the one hand, and the interpretive work that goes into achieving these understandings and evaluations, on the other

A Qualitative Analysis of Students’ Perceptions of Pursuing Pharmacy as a Potential Vocation

We present the findings from a phenomenological, qualitative research study that explored the personal constructs of an inaugural class, entering a newly-established direct-entry, preferred admission, pre-pharmacy program at a private, selective, Midwestern university with an enrollment of 3000. The focus of the study was to appraise students\u27 perceptions regarding their rationale for pursuing a future career in pharmacy. The sample consisted of 36 students (26 females, 10 males). Data was collected via in-depth interviews of each student who had enrolled in the first year of the program. Overall, students demonstrated their belief that they would be a good fit for the pharmacy field and looked forward to enjoying their future profession. Participants also expressed having a penchant for science and healthcare, and having previously interacted with pharmacists and the pharmacy field prior to entering college. Benefits such as salary, job security, and prestige were of secondary importance to students, but they played a role nonetheless, and encouragement from parents and other respected individuals also was significant

The Value of Netnography for Research in HRD

This paper argues for recognition of Netnography as a necessary methodological innovation for HRD research, enabling the field to address emerging research questions and contribute to theory building at the intersection of technology, work and social life. The paper defines ‘netnography’ and introduces its key methodological underpinnings; illustrates its application and procedures; and considers its benefit to HRD research. We identify three opportunities where Netnography can deliver important advances to HRD theory and practice: investigating hard-to-access online work contexts, such as gig work and other forms of precarious working; exploring marginalised, ‘hidden’, or under-researched voices in online spaces; and extending knowledge of learning in hybrid work environments where physical and digital dimensions are intertwined. We conclude with a call to action by HRD scholars to take forward, and further develop, the Netnographic methodology to contribute to new and inclusive theorizing as a basis for advancements in HRD scholarship and practice

Dynamical Arrest in Attractive Colloids: The Effect of Long-Range Repulsion

We study gelation in suspensions of model colloidal particles with short-ranged attractive and long-ranged repulsive interactions by means of three-dimensional fluorescence confocal microscopy. At low packing fractions, particles form stable equilibrium clusters. Upon increasing the packing fraction the clusters grow in size and become increasingly anisotropic until finally associating into a fully connected network at gelation. We find a surprising order in the gel structure. Analysis of spatial and orientational correlations reveals that the gel is composed of dense chains of particles constructed from face-sharing tetrahedral clusters. Our findings imply that dynamical arrest occurs via cluster growth and association.Comment: Final version: Phys. Rev. Lett. 94, 208301 (2005
