Introduction (Watching Jim Crow: The Struggles Over Mississippi Television, 1955-1969.)

The broadcast complex that houses WLBT-TV remains today where it has always been, a few blocks outside the modest cluster of skyscrapers that defines downtown Jackson, Mississippi. Built in the 1950s a short distance from prominent businesses and seats of government, the center\u27s managers have long enjoyed proximity to political and economic power. But as the years have passed, station planners have faced the problem of updating the center\u27s aging physical plant and technologies. The architectural results are an eclectic mix- a layering of the new upon the old- as a consequence of repeated remodeling projects. While the station\u27s original brick facade remains at the public entrance, behind it the furnishings have been dramatically changed to reflect contemporary needs and concerns. Familiar spaces remain but have been transformed: the cramped dressing rooms and viewing areas built to keep Negro performers apart from white audiences have been radically redesigned for contemporary uses. Traces of a past station remain, reconfigured for the present

Inside Job: Diagnosing Bluetooth Lower Layers Using Off-the-Shelf Devices

Bluetooth is among the dominant standards for wireless short-range communication with multi-billion Bluetooth devices shipped each year. Basic Bluetooth analysis inside consumer hardware such as smartphones can be accomplished observing the Host Controller Interface (HCI) between the operating system's driver and the Bluetooth chip. However, the HCI does not provide insights to tasks running inside a Bluetooth chip or Link Layer (LL) packets exchanged over the air. As of today, consumer hardware internal behavior can only be observed with external, and often expensive tools, that need to be present during initial device pairing. In this paper, we leverage standard smartphones for on-device Bluetooth analysis and reverse engineer a diagnostic protocol that resides inside Broadcom chips. Diagnostic features include sniffing lower layers such as LL for Classic Bluetooth and Bluetooth Low Energy (BLE), transmission and reception statistics, test mode, and memory peek and poke

Sexual revictimisation: individual, interpersonal and contextual factors

People who have been sexually abused as children are two to three times more likely to be sexually revictimised in adolescence and/or adulthood. This paper explores the complex array of variables related to sexual revictimisation. Abstract There is a complex array of variables related to sexual revictimisation. Although prevalence is difficult to ascertain, several studies relate that people who have been sexually abused as children are two to three times more likely to be sexually revictimised in adolescence and/or adulthood. Much of the literature on sexual revictimisation focuses on the individual risk factors for the victim/survivor - their risk perception and emotional dysregulation resulting from initial sexual victimisation - and how these create vulnerability for sexual revictimisation. Broader contextual factors beyond the victim/survivor, however, are often ignored. These contextual factors are explored here with a particular emphasis on minority groups, such as people with a disability; gay, lesbian and bisexual people; and Indigenous people. This focus demonstrates that individual risk factors often do not account for how perpetrators may target vulnerable people who have previously been victimised, how community and organisational attitudes and norms may support sexual revictimisation, and how broader social norms create vulnerability for certain groups. A focus on these broader contextual factors helps to inform prevention strategies. Key messages People who are sexually abused in childhood are two to three times more likely to be sexually revictimised in adolescence and/or adulthood. Individual risk factors include a history of child sexual abuse, poor risk perception, emotional dysregulation, cumulative past abuse, family conflict and distress. Broader contextual factors, such as perpetrator tactics, community and organisational attitudes, and social norms, are also risk factors for sexual revictimisation. Those vulnerable to sexual revictimisation, including minority groups such as people with a disability; gay, lesbian and bisexual people; and Indigenous people may require greater support and advocacy in order to alleviate trauma and trauma symptoms, and increase their resilience. Similar strategies used in the sexual violence primary prevention space may be used to prevent sexual revictimisation. This includes respectful relationships education, gender equity principles and a focus on important sites of social norm reproduction, such as sporting sites and the media, to convey messages of respect and equality

Drawing Delicate Connections

This paper discusses the methodology of a current drawing research project investigating delicacy as a value through case studies in other material practices. It reflects upon an interdisciplinary approach to understanding studio practice, specifically the special relationship that would seem to exist between the delicate, the intimate and drawing

Leg disorders in broiler chickens : prevalence, risk factors and prevention

Broiler (meat) chickens have been subjected to intense genetic selection. In the past 50 years, broiler growth rates have increased by over 300% (from 25 g per day to 100 g per day). There is growing societal concern that many broiler chickens have impaired locomotion or are even unable to walk. Here we present the results of a comprehensive survey of commercial flocks which quantifies the risk factors for poor locomotion in broiler chickens.We assessed the walking ability of 51,000 birds, representing 4.8 million birds within 176 flocks.We also obtained information on approximately 150 different management factors associated with each flock. At a mean age of 40 days, over 27.6% of birds in our study showed poor locomotion and 3.3% were almost unable to walk. The high prevalence of poor locomotion occurred despite culling policies designed to remove severely lame birds from flocks. We show that the primary risk factors associated with impaired locomotion and poor leg health are those specifically associated with rate of growth. Factors significantly associated with high gait score included the age of the bird (older birds), visit (second visit to same flock), bird genotype, not feeding whole wheat, a shorter dark period during the day, higher stocking density at the time of assessment, no use of antibiotic, and the use of intact feed pellets. The welfare implications are profound. Worldwide approximately 261010 broilers are reared within similar husbandry systems.We identify a range of management factors that could be altered to reduce leg health problems, but implementation of these changes would be likely to reduce growth rate and production. A debate on the sustainability of current practice in the production of this important food source is required

Eat what you hear: Gustasonic discourses and the material culture of commercial sound recording

This article analyzes discursive linkages between acts of listening and eating within a combined multisensory regime that the authors label the gustasonic. Including both marketing discourses mobilized by the commercial music industry and representations of record consumption in popular media texts, gustasonic discourses have shaped forms and experiences of recorded sound culture from the gramophone era to the present. The authors examine three prominent modalities of gustasonic discourse: (1) discourses that position records as edible objects for physical ingestion; (2) discourses that preserve linkages between listening and eating but incorporate musical recordings into the packaging of other foodstuffs; and (3) discourses of gustasonic distinction that position the listener as someone with discriminating taste. While the gustasonic on one hand serves as an aid to consumerism, it can also cultivate a countervailing collecting impulse that resists music’s commodity status and inscribes sound recording within alternative systems of culture value

Education’s not black and white, it’s vibrant grey

This paper offers a learner’s eye-view of a journey through education, written in an auto-narrative style. Sarah’s story spans from Secondary School to College and through University finishing at the point of Graduation. Revealed in this open and honest account is an insight to coping with home life whilst navigating the trials of the Education system. Sarah makes criticisms of her peers at every level reminding us how competitive some students have to be to get on and achieve success in their education. Critical judgements are also made about Sarah’s School teachers and University lecturers, which are at times as rewarding as they are uncomfortable, but always truthful. Consequently, there is much to learn by both academics and students from this sensitive and vulnerable personal revelation. Sarah’s evidence in turn points to some fundamental questions about the genuine outcomes of the Educational system, e.g. what are we actually teaching young people to be like? And do we like the product in terms of their values, beliefs and motives? A concluding message from Sarah’s perspective is that greater independence in learning, freedom in thinking and equipping people to reason, judge and make decisions in whatever realm, may be defining steps towards becoming educated

Prescribing errors : what’s the story?

Although prescribing errors are one of the most common causes of preventable iatrogenic injury, there have been relatively few studies of their incidence and causes. The majority of the studies that have been carried out have been based in secondary care. This paper reviews what is currently known about prescribing errors. It is suggested that prescribing errors occur in at least 1-2% of all medication orders written, cause harm in about 1% of admissions, and have a wide range of causes. Organisation-wide interventions and cultural changes are likely to be required to prevent them. However, useful first steps suggested include reporting prescribing errors identified, formally reviewing pharmacists’ interventions and developing increased ‘error awareness’ amongst all health care professionals.peer-reviewe
