Electoral fraud or violence: the effect of observers on party manipulation strategies
This article reports on the effects of domestic election observers on electoral fraud and violence. Using an experimental research design and polling station data on fraud and violence during Ghana's 2012 elections, it shows that observers reduced fraud and violence at the polling stations which they monitored. It is argued that local electoral competition shapes party activists' response to observers. As expected, in single-party dominant areas, parties used their local political networks to relocate fraud to polling stations without an election observer, and, in contrast, party activists relocated violence to stations without observers in competitive areas - a response that requires less local organizational capacity. This highlights how local party organization and electoral incentives can shape the manipulative electoral strategies employed by parties in democratic elections
Prisoners\u27 Rights and the Correctional Scheme: The Legal Controversy and Problems of Implementation
Mapping Valley Bottom Confinement at the Network Scale
In this article, we demonstrate the application of a continuous confinement metric across entire river networks. Confinement is a useful metric for characterizing and discriminating valley setting. At the reach scale, valley bottom confinement is measured and quantified as the ratio of the length of channel confined on either bank by a confining margin divided by the reach length. The valley bottom is occupied by the contemporary floodplain and/or its channel(s); confining margins can be any landform or feature that makes up the valley bottom margin, such as bedrock hillslopes, terraces, fans, or anthropogenic features such as stopbanks or constructed levees. To test the reliability of calculating confinement across entire networks, we applied our geoprocessing scripts across four physiographically distinct watersheds of the Pacific Northwest, USA using freely available national datasets. Comparison of manually digitized and mapped with modeled calculations of confinement revealed that roughly one‐third of reaches were equivalent and about two‐thirds of the sites differ by less than ±15%. A sensitivity analysis found that a 500 m reach segmentation length produced reasonable agreement with manual, categorical, expert‐derived analysis of confinement. Confinement accuracy can be improved (c. 4% to 17% gains) using a more accurately mapped valley bottom and channel position (i.e. with higher‐resolution model inputs). This is particularly important when differentiating rivers in the partly confined valley setting. However, at the watershed scale, patterns derived from mapping confinement are not fundamentally different, making this a reasonably accurate and rapid technique for analysis and measurement of confinement across broad spatial extents
The Blurred Line Between Form and Process: A Comparison of Stream Channel Classification Frameworks
Stream classification provides a means to understand the diversity and distribution of channels and floodplains that occur across a landscape while identifying links between geomorphic form and process. Accordingly, stream classification is frequently employed as a watershed planning, management, and restoration tool. At the same time, there has been intense debate and criticism of particular frameworks, on the grounds that these frameworks classify stream reaches based largely on their physical form, rather than direct measurements of their component hydrogeomorphic processes. Despite this debate surrounding stream classifications, and their ongoing use in watershed management, direct comparisons of channel classification frameworks are rare. Here we implement four stream classification frameworks and explore the degree to which each make inferences about hydrogeomorphic process from channel form within the Middle Fork John Day Basin, a watershed of high conservation interest within the Columbia River Basin, U.S.A. We compare the results of the River Styles Framework, Natural Channel Classification, Rosgen Classification System, and a channel form-based statistical classification at 33 field-monitored sites. We found that the four frameworks consistently classified reach types into similar groups based on each reach or segment’s dominant hydrogeomorphic elements. Where classified channel types diverged, differences could be attributed to the (a) spatial scale of input data used, (b) the requisite metrics and their order in completing a framework’s decision tree and/or, (c) whether the framework attempts to classify current or historic channel form. Divergence in framework agreement was also observed at reaches where channel planform was decoupled from valley setting. Overall, the relative agreement between frameworks indicates that criticism of individual classifications for their use of form in grouping stream channels may be overstated. These form-based criticisms may also ignore the geomorphic tenet that channel form reflects formative hydrogeomorphic processes across a given landscape
100 Years of Scientific Evolution of Work and Organizational Psychology: A Bibliometric Network Analysis From 1919 to 2019
In this study, we explore a 100 years of Work and Organizational Psychology (WOP). To do this, we carry out a bibliometric performance and network analysis (BPNA) to understand the evolution structure and the most important themes in the field of study. To perform the BNPA, 8,966 documents published since 1919 were exported from the Web of Science and Scopus databases. The SciMAT software was used to process data and to create the evolution structure, the strategic diagram, and the thematic network structure of the strategic themes of the field of WOP. We identified 29 strategic clusters and discuss the most important themes (motor themes) and their relationship with other clusters. This research presents the complete evolution of the field of study, identifying emerging themes and others with a high degree of development. We hope that this work will support researchers and future research in the field of WOP
Discovery of the First Insect Nidovirus, a Missing Evolutionary Link in the Emergence of the Largest RNA Virus Genomes
Nidoviruses with large genomes (26.3–31.7 kb; ‘large nidoviruses’), including Coronaviridae and Roniviridae, are the most complex positive-sense single-stranded RNA (ssRNA+) viruses. Based on genome size, they are far separated from all other ssRNA+ viruses (below 19.6 kb), including the distantly related Arteriviridae (12.7–15.7 kb; ‘small nidoviruses’). Exceptionally for ssRNA+ viruses, large nidoviruses encode a 3′-5′exoribonuclease (ExoN) that was implicated in controlling RNA replication fidelity. Its acquisition may have given rise to the ancestor of large nidoviruses, a hypothesis for which we here provide evolutionary support using comparative genomics involving the newly discovered first insect-borne nidovirus. This Nam Dinh virus (NDiV), named after a Vietnamese province, was isolated from mosquitoes and is yet to be linked to any pathology. The genome of this enveloped 60–80 nm virus is 20,192 nt and has a nidovirus-like polycistronic organization including two large, partially overlapping open reading frames (ORF) 1a and 1b followed by several smaller 3′-proximal ORFs. Peptide sequencing assigned three virion proteins to ORFs 2a, 2b, and 3, which are expressed from two 3′-coterminal subgenomic RNAs. The NDiV ORF1a/ORF1b frameshifting signal and various replicative proteins were tentatively mapped to canonical positions in the nidovirus genome. They include six nidovirus-wide conserved replicase domains, as well as the ExoN and 2′-O-methyltransferase that are specific to large nidoviruses. NDiV ORF1b also encodes a putative N7-methyltransferase, identified in a subset of large nidoviruses, but not the uridylate-specific endonuclease that – in deviation from the current paradigm - is present exclusively in the currently known vertebrate nidoviruses. Rooted phylogenetic inference by Bayesian and Maximum Likelihood methods indicates that NDiV clusters with roniviruses and that its branch diverged from large nidoviruses early after they split from small nidoviruses. Together these characteristics identify NDiV as the prototype of a new nidovirus family and a missing link in the transition from small to large nidoviruses
Psychological therapies for women who experience intimate partner violence
BACKGROUND: Intimate partner violence (IPV) against women is prevalent and strongly associated with mental health problems. Women experiencing IPV attend health services frequently for mental health problems. The World Health Organization recommends that women who have experienced IPV and have a mental health diagnosis should receive evidence-based mental health treatments. However, it is not known if psychological therapies work for women in the context of IPV and whether they cause harm. OBJECTIVES: To assess the effectiveness of psychological therapies for women who experience IPV on the primary outcomes of depression, self-efficacy and an indicator of harm (dropouts) at six- to 12-months' follow-up, and on secondary outcomes of other mental health symptoms, anxiety, quality of life, re-exposure to IPV, safety planning and behaviours, use of healthcare and IPV services, and social support. SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR), CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, and three other databases, to the end of October 2019. We also searched international trials registries to identify unpublished or ongoing trials and handsearched selected journals, reference lists of included trials and grey literature. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs, cluster-RCTs and cross-over trials of psychological therapies with women aged 16 years and older who self-reported recent or lifetime experience of IPV. We included trials if women also experienced co-existing mental health diagnoses or substance abuse issues, or both. Psychological therapies included a wide range of interventions that targeted cognition, motivation and behaviour compared with usual care, no treatment, delayed or minimal interventions. We classified psychological therapies according to Cochrane Common Mental Disorders's psychological therapies list. DATA COLLECTION AND ANALYSIS: Two review authors extracted data and undertook 'Risk of Bias' assessment. Treatment effects were compared between experimental and comparator interventions at short-term (up to six months post-baseline), medium-term (six to under 12 months, primary outcome time point), and long-term follow-up (12 months and above). We used standardised mean difference (SMD) for continuous and odds ratio (OR) for dichotomous outcomes, and used random-effects meta-analysis, due to high heterogeneity across trials. MAIN RESULTS: We included 33 psychological trials involving 5517 women randomly assigned to experimental (2798 women, 51%) and comparator interventions (2719 women, 49%). Psychological therapies included 11 integrative therapies, nine humanistic therapies, six cognitive behavioural therapy, four third-wave cognitive behavioural therapies and three other psychologically-orientated interventions. There were no trials classified as psychodynamic therapies. Most trials were from high-income countries (19 in USA, three in Iran, two each in Australia and Greece, and one trial each in China, India, Kenya, Nigeria, Pakistan, Spain and UK), among women recruited from healthcare, community, shelter or refuge settings, or a combination of any or all of these. Psychological therapies were mostly delivered face-to-face (28 trials), but varied by length of treatment (two to 50 sessions) and staff delivering therapies (social workers, nurses, psychologists, community health workers, family doctors, researchers). The average sample size was 82 women (14 to 479), aged 37 years on average, and 66% were unemployed. Half of the women were married or living with a partner and just over half of the participants had experienced IPV in the last 12 months (17 trials), 6% in the past two years (two trials) and 42% during their lifetime (14 trials). Whilst 20 trials (61%) described reliable low-risk random-sampling strategies, only 12 trials (36%) described reliable procedures to conceal the allocation of participant status. While 19 trials measured women's depression, only four trials measured depression as a continuous outcome at medium-term follow-up. These showed a probable beneficial effect of psychological therapies in reducing depression (SMD -0.24, 95% CI -0.47 to -0.01; four trials, 600 women; moderate-certainty evidence). However, for self-efficacy, there may be no evidence of a difference between groups (SMD -0.12, 95% CI -0.33 to 0.09; one trial with medium-term follow-up data, 346 women; low-certainty evidence). Further, there may be no difference between the number of women who dropped out from the experimental or comparator intervention groups, an indicator of no harm (OR 1.04, 95% CI 0.75 to 1.44; five trials with medium-term follow-up data, 840 women; low-certainty evidence). Although no trials reported adverse events from psychological therapies or participation in the trial, only one trial measured harm outcomes using a validated scale. For secondary outcomes, trials measured anxiety only at short-term follow-up, showing that psychological therapies may reduce anxiety symptoms (SMD -0.96, 95% CI -1.29 to -0.63; four trials, 158 women; low-certainty evidence). However, within medium-term follow-up, low-certainty evidence revealed that there may be no evidence between groups for the outcomes safety planning (SMD 0.04, 95% CI -0.18 to 0.25; one trial, 337 women), post-traumatic stress disorder (SMD -0.24, 95% CI -0.54 to 0.06; four trials, 484 women) or re-exposure to any form of IPV (SMD 0.03, 95% CI -0.14 to 0.2; two trials, 547 women). AUTHORS' CONCLUSIONS: There is evidence that for women who experience IPV, psychological therapies probably reduce depression and may reduce anxiety. However, we are uncertain whether psychological therapies improve other outcomes (self-efficacy, post-traumatic stress disorder, re-exposure to IPV, safety planning) and there are limited data on harm. Thus, while psychological therapies probably improve emotional health, it is unclear if women's ongoing needs for safety, support and holistic healing from complex trauma are addressed by this approach. There is a need for more interventions focused on trauma approaches and more rigorous trials (with consistent outcomes at similar follow-up time points), as we were unable to synthesise much of the research
