Scholarship funding through strategic reporting: the case of Koro Island

This study used observational and textual analysis to ascertain how the Koro Island Scholarship Fund developed a reporting model to access funding for educational scholarships that facilitated access to high schooling for disadvantaged children in the Lomaiviti Group of Eastern Fiji. The reporting model also provided information to key stakeholders, such as donor groups and aid organizations, for the assessment of student and funding performance. It appears sound financial accountability of a scholarship fund is welcomed by donors. The scholarship fund appeared to work well if there was limited intrusion into the operations of a donee school, providing space for interrelations between traditional Fijian school values, the island landscape and the local conventions and customs

Discovering Representations for Black-box Optimization

The encoding of solutions in black-box optimization is a delicate, handcrafted balance between expressiveness and domain knowledge -- between exploring a wide variety of solutions, and ensuring that those solutions are useful. Our main insight is that this process can be automated by generating a dataset of high-performing solutions with a quality diversity algorithm (here, MAP-Elites), then learning a representation with a generative model (here, a Variational Autoencoder) from that dataset. Our second insight is that this representation can be used to scale quality diversity optimization to higher dimensions -- but only if we carefully mix solutions generated with the learned representation and those generated with traditional variation operators. We demonstrate these capabilities by learning an low-dimensional encoding for the inverse kinematics of a thousand joint planar arm. The results show that learned representations make it possible to solve high-dimensional problems with orders of magnitude fewer evaluations than the standard MAP-Elites, and that, once solved, the produced encoding can be used for rapid optimization of novel, but similar, tasks. The presented techniques not only scale up quality diversity algorithms to high dimensions, but show that black-box optimization encodings can be automatically learned, rather than hand designed.Comment: Presented at GECCO 2020 -- v2 (Previous title 'Automating Representation Discovery with MAP-Elites'

Economic crisis and regional resilience: detecting the ‘geographical footprint’ of economic crisis in Greece

Taking stock from the research on regional resilience and by constructing a composite regional resilience indicator this paper sets out to detect the resistance/vulnerability of Greek regions and prefectures to economic crisis. Analysis is based on a newly elaborated dataset with socio-demographic, economic and welfare variables for Greek regions enabling to pre and after-crisis comparisons. Results highlight the multiplicity of ways in which crisis impacts on regions. Metropolitan areas and regions that are based on manufacturing activities seem to have been more vulnerable to crisis while places that are based on tourism such as islands are usually more resistant. Regional policy seems to be pro-cyclical to economic downturn

Characteristics of Nasal Resonance and Perceptual Rating in Prelingual Hearing Impaired Adults

ObjectivesResonance problems in hearing impaired (HI) individuals have been described as aspects of nasality. However, there are limitations in being able to explain the range of resonance problems. Therefore, this study suggests a perceptual rating that will effectively explain the characteristics of resonance problems in HI individuals.MethodsNasalance scores were obtained from 32 subjects in each of HI and normal hearing (NH) groups using a nasometer. The subjects were categorized into groups based on normal and abnormal nasalance ranges. The abnormal nasalance range group was further divided into hyper-, hypo-, and mixed-nasal groups. Nasalance scores were based the individuals performance in a series of passage and syllable tasks. The perceptual rating was evaluated using a newly introduced tool, 'vertical focus of resonance' (VFR), which focuses on the resonance energy in the frontal, throat, pharyngeal and nasal locations.ResultsThe NH group demonstrated a significantly lower nasalance score in the oral coupling and passage tasks than the HI group. Based on the results of nasalance correlation analysis, the HI group showed highly significant correlations between syllable and passage tasks, as contrasted with the NH group. There were significant differences in VFR between the nasalance types in both the NH and the HI groups.ConclusionThe HI hyper-nasal group showed tendencies of velopharyngeal opening, as opposed to the HI hypo-nasal group which showed tendencies of velopharyngeal closure. The HI mixed-nasal group showed inappropriate coordination of velopharyngeal function. In the HI group, the results of VFR showed that the air flow and the resonance energy were not released from the cavity of resonance. The suggested VFR tool explains the focusing characteristics of resonance energy within a continuation of speech sound regardless of the phonetic environment. Therefore, VFR may be a useful tool in explaining the deviant resonance patterns of HI individuals

‘Making the invisible visible’ through alcohol screening and brief intervention in community pharmacies: an Australian feasibility study

Background: Screening and brief interventions (SBI) for alcohol related problems have been shown to be effective in health settings such as general practice or emergency departments. Recent data from the United Kingdom and New Zealand suggest that SBI can be delivered through community pharmacies, but this approach has not been tested in Australia. This study assesses the feasibility of delivering alcohol SBI via community pharmacists. Method: We recruited five pharmacies and developed an SBI training package to be delivered by pharmacy staff, who screened consumers and delivered the brief intervention where appropriate. Consumers also completed a questionnaire on the process. At three months consumers were telephoned to enable ‘retention’ to be quantified. After completing recruitment, a semi-structured interview was conducted with pharmacists on the process of delivering the intervention, potential improvements and sustainability. Results: Fifty consumer participants were screened, ten from each pharmacy. There were 28 (57 %) men and 21 (43 %) women with one not responding. Most (67 %) were aged 25-55 years. Their AUDIT scores had a range of 0 to 39 (mean 10.9, SD 9.8) with 11 categorised as ‘hazardous (8-15)’, four as ‘harmful (16-19)’ and eight as ‘probably dependent (20+)’ consumers of alcohol. Reactions to the process of SBI were generally favourable: for example 75 % agreed that it was either appropriate or very appropriate being asked about their alcohol consumption. With respect to follow-up interviews, 23 (46 %) agreed that they could be contacted, including five from the highest AUDIT category. Subsequently 11 (48 %) were contactable at three months. Three of the five non-low risk drinkers had reduced their level of risk over the three months. Ten pharmacists participated in semi-structured telephone interviews. Overall these pharmacists were positive about the intervention and five main themes emerged from the interviews: 1) flexibility applied in recruitment of participants, 2) easiness in use of AUDIT score to facilitate discussions, 3) perceived positive intervention impact, 4) enhanced role of community pharmacists and 5) facilitators and challenges experienced. Conclusions: Pharmacy-based SBI appears to be acceptable to consumers and feasible for pharmacy staff to deliver. Challenges remain in translating this potential into actual services

Vibrio cholerae vexH Encodes a Multiple Drug Efflux Pump That Contributes to the Production of Cholera Toxin and the Toxin Co-Regulated Pilus

The resistance-nodulation-division (RND) efflux systems are ubiquitous transporters that function in antimicrobial resistance. Recent studies showed that RND systems were required for virulence factor production in Vibrio cholerae. The V. cholerae genome encodes six RND efflux systems. Three of the RND systems (VexB, VexD, and VexK) were previously shown to be redundant for in vitro resistance to bile acids and detergents. A mutant lacking the VexB, VexD, and VexK RND pumps produced wild-type levels of cholera toxin (CT) and the toxin co-regulated pilus (TCP) and was moderately attenuated for intestinal colonization. In contrast, a RND negative mutant produced significantly reduced amounts of CT and TCP and displayed a severe colonization defect. This suggested that one or more of the three uncharacterized RND efflux systems (i.e. VexF, VexH, and VexM) were required for pathogenesis. In this study, a genetic approach was used to generate a panel of V. cholerae RND efflux pump mutants in order to determine the function of VexH in antimicrobial resistance, virulence factor production, and intestinal colonization. VexH contributed to in vitro antimicrobial resistance and exhibited a broad substrate specificity that was redundant with the VexB, VexD, and VexK RND efflux pumps. These four efflux pumps were responsible for in vitro antimicrobial resistance and were required for virulence factor production and intestinal colonization. Mutation of the VexF and/or VexM efflux pumps did not affect in vitro antimicrobial resistance, but did negatively affect CT and TCP production. Collectively, our results demonstrate that the V. cholerae RND efflux pumps have redundant functions in antimicrobial resistance and virulence factor production. This suggests that the RND efflux systems contribute to V. cholerae pathogenesis by providing the bacterium with protection against antimicrobial compounds that are present in the host and by contributing to the regulated expression of virulence factors

Intervention Now to Eliminate Repeat Unintended Pregnancy in Teenagers (INTERUPT): a systematic review of intervention effectiveness and cost-effectiveness, and qualitative and realist synthesis of implementation factors and user engagement

Background The UK has one of the highest rates of teenage pregnancies in Western Europe. One-fifth of these are repeat pregnancies. Unintended conceptions can cause substantial emotional, psychological and educational harm to teenagers, often with enduring implications for life chances. Babies of teenage mothers have increased mortality and are at a significantly increased risk of poverty, educational underachievement and unemployment later in life, with associated costs to society. It is important to identify effective, cost-effective and acceptable interventions. Objectives To identify who is at the greatest risk of repeat unintended pregnancies; which interventions are effective and cost-effective; and what the barriers to and facilitators of the uptake of these interventions are. Data sources We conducted a multistreamed, mixed-methods systematic review informed by service user and provider consultation to examine worldwide peer-reviewed evidence and UK-generated grey literature to find and evaluate interventions to reduce repeat unintended teenage pregnancies. We searched the following electronic databases: MEDLINE and MEDLINE In-Process & Other Non-Indexed Citations, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library (Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and the Health Technology Assessment Database), EMBASE (Excerpta Medica database), British Nursing Index, Educational Resources Information Center, Sociological Abstracts, Applied Social Sciences Index and Abstracts, BiblioMap (the Evidence for Policy and Practice Information and Co-ordinating Centre register of health promotion and public health research), Social Sciences Citation Index (supported by Web of Knowledge), Research Papers in Economics, EconLit (American Economic Association’s electronic bibliography), OpenGrey, Scopus, Scirus, Social Care Online, National Research Register, National Institute for Health Research Clinical Research Network Portfolio and Index to THESES. Searches were conducted in May 2013 and updated in June 2014. In addition, we conducted a systematic search of Google (Google Inc., Mountain View, CA, USA) in January 2014. Database searches were guided by an advisory group of stakeholders. Review methods To address the topic’s complexities, we used a structured, innovative and iterative approach combining methods tailored to each evidence stream. Quantitative data (effectiveness, cost-effectiveness, risk factors and effect modifiers) were synthesised with reference to Cochrane guidelines for evaluating evidence on public health interventions. Qualitative evidence addressing facilitators of and barriers to the uptake of interventions, experience and acceptability of interventions was synthesised thematically. We applied the principles of realist synthesis to uncover theories and mechanisms underpinning interventions (what works, for whom and in what context). Finally, we conducted an overarching narrative of synthesis of evidence and gathered service user feedback. Results We identified 8664 documents initially, and 816 in repeat searches. We filtered these to 12 randomised controlled trials (RCTs), four quasi-RCTs, 10 qualitative studies and 53 other quantitative studies published between 1996 and 2012. None of the RCTs was based in the UK. The RCTs evaluated an emergency contraception programme and psychosocial interventions. We found no evidence for effectiveness with regard to condom use, contraceptive use or rates of unprotected sex or use of birth control. Our primary outcome was repeat conception rate: the event rate was 132 of 308 (43%) in the intervention group versus 140 of 289 (48%) for the control goup, with a non-significant risk ratio (RR) of 0.92 [95% confidence interval (CI) 0.78 to 1.08]. Four studies reported subsequent birth rates: 29 of 237 (12%) events for the intervention arm versus 46 out of 224 (21%) for the control arm, with a RR of 0.60 (95% CI 0.39 to 0.93). Many repeat conceptions occurred in the context of poverty, low expectations and aspirations, and negligible opportunities. Service user feedback suggested that there were specific motivations for many repeat conceptions, for example to replace loss or to please a partner. Realist synthesis highlighted that context, motivation, planning for the future and letting young women take control with connectedness and tailoring provide a conceptual framework for future research. Limitations Included studies rarely characterised adolescent pregnancy as intended or unintended, that is interventions to reduce repeat conceptions rarely addressed whether or not pregnancies were intended. Furthermore, interventions were often not clearly defined, had multiple aims and did not indicate which elements were intended to address which aims. Nearly all of the studies were conducted in the USA and focused largely on African American or Hispanic and Latina American populations. Conclusions We found no evidence to indicate that existing interventions to reduce repeat teenage pregnancy were effective; however, subsequent births were reduced by home-based interventions. Qualitative and realist evidence helped to explain gaps in intervention design that should be addressed. More theory-based, rigorously evaluated programmes need to be developed to reduce repeat teenage pregnancy in the UK. Study registration This study is registered as PROSPERO CRD42012003168.
