Optical Design for Li Beam Zeeman Polarimetry Measurements on Diii-D

Measurements of the magnetic field pitch angle are obtained from the polarization characteristics of the {sigma} component of the Zeeman triplet of Li emission at 670.8 nm. A four element optical system images a horizontal Li beam on an array of 3 x 32, 1 mm diam. optical fibers, providing 32 spatial channels with 5 mm radial resolution in the plasma. Low Verdet constant glass is used for all optical elements near the DIII-D vessel to minimize the effects of Faraday rotation caused by stray magnetic fields. Before entering the fiber optics, the light passes through two crossed (45 degrees) photoelastic modulators (PEM) and a linear polarizer, which convert the various polarization states into an intensity modulated signal at the fundamental and 2nd harmonic of the PEM frequencies. For each spatial channel, light from a three fiber bundle is collimated and passes through a temperature tuned etalon (free spectral range, FSR = 0.3 nm; finesse, F = 5.7) in order to select only one {sigma} line of the triplet. The FSR is large enough to adequately cover the expected Zeeman triplet and small enough to achieve a low bandwidth (0.06 nm) at reasonably low F. A 1.0 nm wide interference filter is used to block all but 4-5 peaks of the etalon. The light is then focused on GaAs photo multiplier detectors. Details of the design and performance are presented

Dangerous work: The gendered nature of bullying in the context of higher education

This paper discusses results from a research project which set out to investigate gender differences in the nature and experience of bullying within the higher education sector. Gender differences emerged in the form and perception of bullying as well as in target response. Results also indicate that, irrespective of gender, bullies can capture and subvert organizational structures and procedures (official hierarchies, mentoring systems, probationary reviews) to further their abuse of the target and to conceal aggressive intent. These outcomes are discussed in relation to gendered assumptions behind management practices and in relation to the masculinist ethic that underpins many higher education management initiatives. Overall, results indicate that bullying cannot be divorced from gender and that such behaviour needs to be seen in a gendered context

On our own terms : the working conditions of internet-based sex workers in the UK

The sex industry is increasingly operated through online technologies, whether this is selling services online through webcam or advertising, marketing or organising sex work through the Internet and digital technologies. Using data from a survey of 240 internet-based sex workers (members of the National Ugly Mug reporting scheme in the UK), we discuss the working conditions of this type of work. We look at the basic working patterns, trajectories and everyday experiences of doing sex work via an online medium and the impact this has on the lives of sex workers. For instance, we look at levels of control individuals have over their working conditions, prices, clientele and services sold, and discuss how this is mediated online and placed in relation to job satisfaction. The second key finding is the experience of different forms of crimes individuals are exposed to such as harassment and blackmail via the new technologies. We explore the relationship internet-based sex workers have with the police and discuss how current laws in the UK have detrimental effects in terms of safety and access to justice. These findings are placed in the context of the changing landscape of sex markets as the digital turn determines the nature of the majority of commercial sex encounters. These findings contribute significantly to the populist coercion/choice political debates by demonstrating levels and types of agency and autonomy experienced by some sex workers despite working in a criminalized, precarious and sometimes dangerous context

Women’s experiences of menopause at work and performance management

Presenting findings from our global evidence review of menopause transition and economic participation emboldened us to establish a menopause policy at the university where we all worked at the time. Our report was published in July 2017 and the policy was in place by November that year. Our critical reflection on this activism focuses on issues that are not commonly recognized around such interventions, and which we ourselves have only been able to acknowledge through engaged action. Challenges remain in normalizing menopause in organizations, specifically around gendered ageism and performance management. In drawing on Meyerson and Kolb’s framework for understanding gender in organizations, we highlight how policies are both vital and yet insufficient in and of themselves in revising the dominant discourse around menopause at work. At the same time, we highlight the importance and shortcomings of academic activism within these processes

Democratization and the Diffusion of Shari'a Law: Comparative Insights from Indonesia

The democratization of politics has been accompanied by a rise of Islamic laws in many Muslim-majority countries. Despite a growing interest in the phenomenon, the Islamization of politics in democratizing Muslim-majority countries is rarely understood as a process that unfolds across space and time. Based on an original dataset established during years of field research in Indonesia, this article analyzes the spread of shari’a regulations across the world’s largest Muslim-majority democracy since 1998. The article shows that shari’a regulations in Indonesia diffused unevenly across space and time. Explanations put forward in the literature on the diffusion of morality policies in other countries such as geographic proximity, institutions, intergovernmental relations and economic conditions did not explain the patterns in the diffusion of shari’a regulations in Indonesia well. Instead, shari’a regulations in Indonesia were most likely to spread across jurisdictions where local Islamist groups situated outside the party system had an established presence. In short, the Islamization of politics was highly contingent on local conditions. Future research will need to pay more attention to local Islamist activists and networks situated outside formal politics as potential causes for the diffusion of shari’a law in democratizing Muslim-majority countries

A plan for play - An Eye View Series report

There is a simple, inexpensive and joyful way to address many of the major challenges facing society and its children; addressing the alarming mental health crisis and obesity epidemic and helping to prepare children for an ever-changing work force. The solution that is all too often overlooked and neglected is - play. The right to play is so important that it is enshrined in the UN Convention on the Rights of the Child. Research documents its importance to every aspect of child health, development and wellbeing. Yet many children have little or no access to high quality play opportunities. Play provision should be considered in relation to every aspect of children’s lives – the design of their neighbourhoods, as well as within the services they access, such as child care centres, schools, hospitals, recreation facilities, parks and adventure playgrounds. Play cannot be relegated to the places and context that adults decide are appropriate It should be woven into the fabric of every aspect of children’s lives and the communities they are part of. Equitable access to play means reducing the insidious gradient of inequity that impacts children’s lives even before they are born and continues across their lifespan. Schools are one important venue to ensure equitable access to play. For some children, it will be the only opportunity they have for this nourishing and necessary activity. Play comprises a quarter of the school year, yet teachers and support staff receive no proper training or support to ensure that children in their care – our society’s future – have fulfilling play time. We know that early life experiences set the stage for the future, and that early intervention saves unquantifiable and unnecessary suffering and costs later on – for children, families and society as a whole. We owe it to children and ourselves both now and tomorrow, to make a plan for play that sees every child in every place playing every day. This report makes that case

Involvement of Complexin 2 in Docking, Locking and Unlocking of Different SNARE Complexes during Sperm Capacitation and Induced Acrosomal Exocytosis

Acrosomal exocytosis (AE) is an intracellular multipoint fusion reaction of the sperm plasma membrane (PM) with the outer acrosomal membrane (OAM). This unique exocytotic event enables the penetration of the sperm through the zona pellucida of the oocyte. We previously observed a stable docking of OAM to the PM brought about by the formation of the trans-SNARE complex (syntaxin 1B, SNAP 23 and VAMP 3). By using electron microscopy, immunochemistry and immunofluorescence techniques in combination with functional studies and proteomic approaches, we here demonstrate that calcium ionophore-induced AE results in the formation of unilamellar hybrid membrane vesicles containing a mixture of components originating from the two fused membranes. These mixed vesicles (MV) do not contain the earlier reported trimeric SNARE complex but instead possess a novel trimeric SNARE complex that contained syntaxin 3, SNAP 23 and VAMP 2, with an additional SNARE interacting protein, complexin 2. Our data indicate that the earlier reported raft and capacitation-dependent docking phenomenon between the PM and OAM allows a specific rearrangement of molecules between the two docked membranes and is involved in (1) recruiting SNAREs and complexin 2 in the newly formed lipid-ordered microdomains, (2) the assembly of a fusion-driving SNARE complex which executes Ca2+-dependent AE, (3) the disassembly of the earlier reported docking SNARE complex, (4) the recruitment of secondary zona binding proteins at the zona interacting sperm surface. The possibility to study separate and dynamic interactions between SNARE proteins, complexin and Ca2+ which are all involved in AE make sperm an ideal model for studying exocytosis

Writing as skin:Negotiating the body in(to) learning about the managed self

We draw on the notion of ‘skin’ to discuss the ways in which writing in management and organisation studies wrestles with two drives in its endeavour to represent the reality of our ‘organised’ lives: the drive to share internal lived experience, and the drive to externalise and abstract. Through exploring skin as a metaphor for a negotiating interface between these forces in our writing, we (a) argue that both are critical parts of writing, needed in order to learn about management and organisation and (b) explore different ways in which they might be brought into contact. Reviewing, synthesising and building on critiques of ‘scientific’ writing that have been made from within management and organisation studies, and on creative commentary from the arts, we think reflexively about the ways in which writing mediates learning by being both representative of experience and an experience in itself. A collaboration between management scholar and creative writer, the text of this article is a critical-creative experiment that outlines the experiential ‘skin-text’ while simultaneously producing an example of such a text.</p
