Impact Evaluation of the SADA Millennium Villages Project in Northern Ghana: Endline Summary Report
The Millennium Villages Project (MVP) aims to demonstrate how the Millennium Development Goals (MDGs) could be achieved locally through an integrated approach to development. While the MDGs have now been superseded by the Sustainable Development Goals (SDGs, 2016–30), there remains a consistent thread to
the MDGs around issues such as eradicating poverty, preventing avoidable deaths and improving education.
Furthermore, the interconnected nature of the SDGs means the MVP model also has relevance for those seeking to address extreme poverty by taking an integrated approach to sustainable development.
This report summarises the findings from what we believe to be the first independent impact evaluation of the MVP approach. It is hoped that the evidence and analysis will be of relevance to a wide range of actors in international development.Department for International Development (DFID
'New to me': changing patient understanding of psoriasis and identifying mechanisms of change. The Pso Well® patient materials mixed-methods feasibility study
BACKGROUND: Psoriasis is an inflammatory long-term condition involving comorbidities, unhealthy lifestyle and significant life impact. Patients' understanding of psoriasis is limited and support lacking. The Common-Sense Model of Self-Regulation of Health and Illness emphasizes the role of illness and treatment beliefs on coping and self-management. New 'Pso Well® ' patient materials informed by the model, addressed psoriasis as a long-term condition, medication management and lifestyle behaviours.
OBJECTIVES: To investigate whether Pso Well® materials (i) broaden understanding of psoriasis without increasing anxiety; (ii) are acceptable; and (iii) comprise features that appear to effect change.
METHODS: The Revised Illness Perceptions Questionnaire (IPQ-R modified) and the Hospital Anxiety and Depression Scale (HADS) were administered in patients before and after intervention. Numerical rating scales assessed perceptions of change in understanding and anxiety resulting from engagement with the materials. Qualitative interviews explored acceptability and perceived 'active ingredients'.
RESULTS: Fifty-five patients completed pre- and postintervention questionnaires (56% female; median age 59 years). Postintervention, a large effect size was indicated in two IPQ-R domains - illness coherence [t(55) = -3·48, P = 0·001 (two-tailed), η2 = 0·19] and personal control [t(55) = -2·98, P = 0·004 (two-tailed), η2 = 0·14] - and a medium effect in one, treatment control [t(55) = -2·08, P = 0·042 (two-tailed), η2 = 0·08]. HADS scores did not change. For numerical rating scales, 80% of participants reported increased understanding of psoriasis and none reported increased anxiety. Interviews with 19 patients indicated the materials were acceptable and usable. Factors reported to broaden understanding and promote engagement with self-management included linking of related disease aspects, personally relevant content and high-quality design.
CONCLUSIONS: High-quality, theory-based psoriasis materials are acceptable to patients and can improve understanding and sense of control without increasing anxiety
A Study on the Effects of Ball Defects on the Fatigue Life in Hybrid Bearings
Hybrid ball bearings using silicon nitride ceramic balls with steel rings are increasingly being used in space mechanism applications due to their high wear resistance and long rolling contact fatigue life. However, qualitative and quantitative reports of the effects of ball defects that cause early fatigue failure are rare. We report on our approach to study these effects. Our strategy includes characterization of defects encountered in use, generation of similar defects in a laboratory setting, execution of full-scale bearing tests to obtain lifetimes, post-test characterization, and related finite-element modeling to understand the stress concentration of these defects. We have confirmed that at least one type of defect of appropriate size can significantly reduce fatigue life. Our method can be used to evaluate other defects as they occur or are encountered
Potencial de regeneração natural de um plantio compensatório realizado em unidade de conservação urbana sob forte pressão antrópica
Protected areas by the law represent one of the strategies for biodiversity conservation, especially in regions under strong human pressure. However, many of these protected areas present barriers that prevent natural regeneration and knowing them becomes essential. In this sense, the objective of this work was to verify the regeneration potential of a restoration plantation carried out in a Conservation Unit, by quantifying the contribution of diaspores and the formation of young individuals. Seed collectors and natural regeneration plots were launched in a plantation carried out at the Fontes do Ipiranga State Park, São Paulo, SP. 54 species (41 arboreal) were identified and 24,033 propagules (17,775 of the invasive species Urochloa decumbens) were registered and regarding seedling recruitment there were 58 species (16 arboreal). The regeneration potential was still greatly influenced by the conditions of the area and the strong presence of invasive grasses, combined with the low diversity of tree species identified in the seed rain and in the recruitment of seedlings, had compromised the process.Áreas protegidas por lei representam uma das estratégias para conservação da biodiversidade, principalmente em regiões sob forte pressão antrópica. Porém, muitas dessas áreas protegidas apresentam barreiras impeditivas à regeneração natural e conhecê-las torna-se primordial. Nesse sentido, o objetivo deste trabalho foi verificar o potencial de regeneração de um plantio de restauração realizado em uma Unidade de Conservação, por meio da quantificação do aporte de diásporos e da formação de indivíduos jovens. Para isso, foram instalados coletores de sementes e parcelas de regeneração natural num plantio realizado no Parque Estadual das Fontes do Ipiranga, São Paulo, SP. Foram identificadas 54 espécies (41 arbóreas) e registrados 24.033 propágulos (17.775 da espécie invasora Urochloa decumbens) e quanto ao recrutamento de plântulas foram 58 espécies (16 arbóreas). O potencial de regeneração foi influenciado pelas condições da área, e a forte presença de gramíneas invasoras, aliada à baixa diversidade de espécies arbóreas identificadas na chuva de sementes e no recrutamento de plântulas, tem comprometido o processo
Employee Attributions of the Why of HR Practices: Their Effects on Employee Attitudes and Behaviors, and Customer Satisfaction
The construct of Human Resource (HR) Attributions is introduced. We argue that the attributions that employees make about the reasons why management adopts the HR practices that it does have consequences for their attitudes and behaviors, and ultimately, unit performance. Drawing on the strategic HR literature, we propose a typology of five HR-Attribution dimensions. Utilizing data collected from a service firm, we show that employees make varying attributions for the same HR practices, and that these attributions are differentially associated with commitment and satisfaction. In turn, we show that these attitudes become shared within units and that they are related to unit-level organizational citizenship behaviors and customer satisfaction. Findings and implications are discussed

Continuous Integration (CI) Needs and Wishes for Developers of Proprietary Code
Continuous integration (CI) systems automate the compilation, building, and testing of software. Despite CI being one of the most widely used processes in software engineering, we do not know what motivates developers to use CI, and what barriers and unmet needs they face. Without such knowledge developers make easily avoidable errors, managers reduce the productivity of developers by making misinformed decisions, tool builders invest in the wrong direction, and researchers miss many opportunities for improving the software engineering practice. Given the large fraction of proprietary code development, understanding how proprietary developers are using CI is vital to improving it.
We present the first study of how CI is used in the proprietary development of software. We conduct 16 semi-structured interviews with developers from different industries and development scale. We generalize these findings by surveying 523 developers from all over the world. We find that 78% of developers feel more productive when using CI, and 85% think that using CI causes developers to give more value to automated testing. However, unlike open-source developers, many proprietary developers want to use CI but are not allowed to do so. 50% of developers have problems troubleshooting CI builds, and more than half of developers want easier configurations for CI tools and services
Primary care nurses' experiences of how the mass media influence frontline healthcare in the UK
Background:
Mass media plays an important role in communicating about health research and services to patients, and in shaping public perceptions and decisions about health. Healthcare professionals also play an important role in providing patients with credible, evidence-based and up-to-date information on a wide range of health issues. This study aims to explore primary care nurses' experiences of how mass media influences frontline healthcare.<p></p>
Methods:
In-depth telephone interviews were carried out with 18 primary care nurses (nine health visitors and nine practice nurses) working in the United Kingdom (UK). Interviews were recorded and transcribed. The data was analysed using thematic analysis, with a focus on constant comparative analysis.<p></p>
Results:
Three themes emerged from the data. First, participants reported that their patients were frequently influenced by controversial health stories reported in the media, which affected their perceptions of, and decisions about, care. This, in turn, impinged upon participants' workloads as they had to spend additional time discussing information and reassuring patients. Second, participants also recalled times in their own careers when media reports had contributed to a decline in their confidence in current healthcare practices and treatments. Third, the participants in this study suggested a real need for additional resources to support and expand their own media literacy skills, which could be shared with patients.<p></p>
Conclusion:
In an ever expanding media landscape with greater reporting on health, nurses working in the primary care setting face increasing pressure to effectively manage media stories that dispute current health policies and practices. These primary care nurses were keen to expand their media literacy skills to develop critical autonomy in relation to all media, and to facilitate more meaningful conversations with their patients about their health concerns and choices.<p></p>
A review of the systematic biology of fossil and living bony-tongue fishes, Osteoglossomorpha (Actinopterygii: Teleostei)
The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of morphological, systematic, and evolutionary study, due in part to their basal position among extant teleostean fishes. This group includes the mooneyes (Hiodontidae), knifefishes (Notopteridae), the abu (Gymnarchidae), elephantfishes (Mormyridae), arawanas and pirarucu (Osteoglossidae), and the African butterfly fish (Pantodontidae). This morphologically heterogeneous group also has a long and diverse fossil record, including taxa from all continents and both freshwater and marine deposits. The phylogenetic relationships among most extant osteoglossomorph families are widely agreed upon. However, there is still much to discover about the systematic biology of these fishes, particularly with regard to the phylogenetic affinities of several fossil taxa, within Mormyridae, and the position of Pantodon. In this paper we review the state of knowledge for osteoglossomorph fishes. We first provide an overview of the diversity of Osteoglossomorpha, and then discuss studies of the phylogeny of Osteoglossomorpha from both morphological and molecular perspectives, as well as biogeographic analyses of the group. Finally, we offer our perspectives on future needs for research on the systematic biology of Osteoglossomorpha
Glioblastoma multiforme with oligodendroglial component (GBMO): favorable outcome after post-operative radiotherapy and chemotherapy with nimustine (ACNU) and teniposide (VM26)
BACKGROUND: The presence of an oligodendroglial component within a glioblastoma multiforme (GBM) is considered a prognostically favorable factor, but the clinical outcome of patients with glioblastoma multiforme with oligodendroglial component (GBMO) after combined post-operative radiotherapy and chemotherapy has rarely been reported. METHODS: We analyzed overall and progression-free survival in a group of ten consecutive patients initially diagnosed with GBMO between 1996 and 2004 (4.2% of all GBM patients). Median (range) age was 54 (34–73) years, 90% were resected and median radiotherapy dose was 54 (45–60.6) Gy. 80% of patients received post-operative chemotherapy with nimustine (ACNU) and VM26 (teniposide) for a median of 3.5 (1–6) cycles, the remainder were treated with post-operative radiotherapy alone. All specimens were reviewed by an experienced neuropathologist. RESULTS: Neuropathological re-evaluation revealed GBM with an oligodendroglial component of 30% or less in five cases, predominant oligoastrocytic tumors with focal areas of GBM in four patients and WHO grade III oligoastrocytoma with questionable transition to GBM in one patient. Four of ten patients were alive at at 40, 41, 41 and 82 months. The median overall survival (Kaplan-Meier) was 26 months, the 2-year survival rate was 60% (progression-free survival: 9.8 months and 40%, respectively). CONCLUSION: In conclusion, patients with GBMO treated with post-operative radiotherapy and chemotherapy with ACNU/VM26 had a better prognosis than reported for GBM in modern chemoradiation series
