    ā€œFilling out the Forms was a Nightmareā€: project evaluation and the reflective practitioner in community theatre in contemporary Northern Ireland

    Since the Good Friday Agreement of 1998, large sums have been invested in community theatre projects in Northern Ireland, in the interests of conflict transformation and peace building. While this injection of funds has resulted in an unprecedented level of applied theatre activity, opportunities to maximise learning from this activity are being missed. It is generally assumed that project evaluation is undertaken at least partly to assess the degree of success of projects against important social objectives, with a view to learning what works, what does not, and what might work in the future. However, three ethnographic case studies of organisations delivering applied theatre projects in Northern Ireland indicate that current processes used to evaluate such projects are both flawed and inadequate for this purpose. Practitioners report that the administrative work involved in applying for and justifying funding is onerous, burdensome, and occurs at the expense of artistic activity. This is a very real concern when the time and effort devoted to ā€˜filling out the formsā€™ does not ultimately result in useful evaluative information. There are strong disincentives for organisations to report honestly on their experiences of difficulties, or undesirable impacts of projects, and this problem is not transcended by the use of external evaluators. Current evaluation processes provide little opportunity to capture unexpected benefits of projects, and small but significant successes which occur in the context of over-ambitious objectives. Little or no attempt is made to assess long-term impacts of projects on communities. Finally, official evaluation mechanisms fail to capture the reflective practice and dialogic analysis of practitioners, which would richly inform future projects. The authors argue that there is a need for clearer lines of communication, and more opportunities for mutual learning, among stakeholders involved in community development. In particular, greater involvement of the higher education sector in partnership with government and non-government agencies could yield significant benefits in terms of optimizing learning from applied theatre project evaluations

    Domestic Assault by Strangulation and Recantation of Victims in the Criminal Court System

    In addition to being established by research to lead to serious health concerns and known as the ultimate form of power and control over victims, domestic assault by strangulation is also a precursor to future homicide by an intimate partner. For these reasons, further attention to domestic assault by strangulation is needed in order to better understand the scope of client services needed, due to its 1) association with criminal case recantation and 2) safety concerns due to being a predictor of future homicide. By using the Power and Control Wheel (Domestic Abuse Programs, n.d) as a method to interpret and further understand the data, the researcher created a thirteen question survey distributed to professionals working in the field with victims of domestic violence. The qualitative survey was designed to address the two-part research question: 1) What causes a victim to recant or refuse case involvement in non-fatal domestic assault by strangulation cases and 2) What are some possible ways that a criminal conviction can be secured when warranted, in the context of strangulation, without putting undue pressure on the victim to testify? As a result of the survey data collected, eleven main themes emerged from participant responses. These survey findings were consistent with the findings of the literature review; however several key differences were noted

    Trust-Based Mechanisms for Robust and Efficient Task Allocation in the Presence of Execution Uncertainty

    Get PDF
    Vickrey-Clarke-Groves (VCG) mechanisms are often used to allocate tasks to selfish and rational agents. VCG mechanisms are incentive-compatible, direct mechanisms that are efficient (i.e. maximise social utility) and individually rational (i.e. agents prefer to join rather than opt out). However, an important assumption of these mechanisms is that the agents will always successfully complete their allocated tasks. Clearly, this assumption is unrealistic in many real-world applications where agents can, and often do, fail in their endeavours. Moreover, whether an agent is deemed to have failed may be perceived differently by different agents. Such subjective perceptions about an agentā€™s probability of succeeding at a given task are often captured and reasoned about using the notion of trust. Given this background, in this paper, we investigate the design of novel mechanisms that take into account the trust between agents when allocating tasks. Specifically, we develop a new class of mechanisms, called trust-based mechanisms, that can take into account multiple subjective measures of the probability of an agent succeeding at a given task and produce allocations that maximise social utility, whilst ensuring that no agent obtains a negative utility. We then show that such mechanisms pose a challenging new combinatorial optimisation problem (that is NP-complete), devise a novel representation for solving the problem, and develop an effective integer programming solution (that can solve instances with about 2Ɨ105 possible allocations in 40 seconds).

    Untold Perspectives: The Impact of the Closure of a Health Institution in a Black Community in North St. Louis County

    Based on the literature of social determinants of health, health equity, and anchor institutions, it is evident that hospitals have a role to play in ensuring the health of their community. However, our understanding of the impact of hospital closures is limited, especially when it comes to Black communities. The purpose of this study is to examine the relationship of the closure of the Normandy Osteopathic Hospital to the social determinants of healthā€”specifically access to care and economic stability as it relates to income and wealth generationā€”for a Black community in one near-North suburb of St. Louis. Ten individuals with a connection to the Normandy Osteopathic Hospital were interviewed using qualitative methods and an oral history protocol. Data was coded and analyzed using thematic analysis. Findings showed layers of disinvestment over time through national and local health care management decisions. Findings also showed that the hospital closure not only had an impact on access to health care, but also on community self-worth and economic wellbeing. As a result of these findings, policy implications and recommendations are explored

    Cooperative population coding facilitates efficient sound-source separability by adaptation to input statistics

    Our sensory environment changes constantly. Accordingly, neural systems continually adapt to the concurrent stimulus statistics to remain sensitive over a wide range of conditions. Such dynamic range adaptation (DRA) is assumed to increase both the effectiveness of the neuronal code and perceptual sensitivity. However, direct demonstrations of DRA-based efficient neuronal processing that also produces perceptual benefits are lacking. Here, we investigated the impact of DRA on spatial coding in the rodent brain and the perception of human listeners. Complex spatial stimulation with dynamically changing source locations elicited prominent DRA already on the initial spatial processing stage, the Lateral Superior Olive (LSO) of gerbils. Surprisingly, on the level of individual neurons, DRA diminished spatial tuning because of large response variability across trials. However, when considering single-trial population averages of multiple neurons, DRA enhanced the coding efficiency specifically for the concurrently most probable source locations. Intrinsic LSO population imaging of energy consumption combined with pharmacology revealed that a slow-acting LSO gain-control mechanism distributes activity across a group of neurons during DRA, thereby enhancing population coding efficiency. Strikingly, such "efficient cooperative coding" also improved neuronal source separability specifically for the locations that were most likely to occur. These location-specific enhancements in neuronal coding were paralleled by human listeners exhibiting a selective improvement in spatial resolution. We conclude that, contrary to canonical models of sensory encoding, the primary motive of early spatial processing is efficiency optimization of neural populations for enhanced source separability in the concurrent environment

    Endangered Archaeology in the Middle East and North Africa: Introducing the EAMENA Project

    Get PDF
    This project uses satellite imagery and historic aerial photographs to discover and interpret archaeological sites. It has created an open access database of archaeological records that provides basic information so that the sites can be better under- stood and preserved in the future. The threats to sites in the Middle East and North Africa are increasing and creating a record of previously unrecorded sites using this methodology may be our the last chance before they are destroyed
