The Global Economy and Changes in the Determinants of Cross-National Income Inequality

This study examines the capacity of modernization theory, dependency theory, world-system analysis, and political democracy theory to explain the determinants of income inequality in less-developed countries before and after major structural economic changes,stemming from the collapse of the Bretton Woods system in 1971 and the OPEC oil crisis in 1973 and 1974, occurred in the global economy. Data from two cohorts of countries are used to test these theories. The first cohort contains thirty-three countries with data on income inequality between 1968 and 1973, and the second cohort contains thirty-one countries with data on income inequality between 1985 and 1992. The results suggest that world-system analysis and some aspects of dependency theory are relevant to explaining income inequality both before and after the global changes.. However, modernization theory and political democracy theory are only predictive of levels of income inequality before changes in the global economy occurred. Overall, the results of this research highlight the importance of integrating historical shifts in the global economy into theories of income inequality

Eyes Wide Shut: Using Accreditation Regulation to Address the “Pass-the-Harasser” Problem in Higher Education

The #MeToo Movement cast a spotlight on sexual harassment in various sectors, including higher education. Studies reveal alarming percentages of students reporting that they have been sexually harassed by faculty and administrators. Despite annually devoting hundreds of millions of dollars to addressing sexual harassment and misconduct, nationwide university officials largely take an ostrich approach when hiring faculty and administrators with little or no scrutiny related to their past misconduct. Critics use the term “pass the harasser” or more pejoratively, “pass the trash” to capture the role that institutions play in allowing individuals to change institutions without the new employer learning about the employee’s prior sexual misconduct. This essay examines how and why the pass-the-harasser phenomenon arises and persists in postsecondary institutions, as well as recent changes two university systems and one state have made to deal with the problem. Although these efforts are commendable, experts recognize that the pass-the-harasser problem requires concerted action by institutions across the country. To push universities and colleges to become part of the collective solution, the essay proposes that accrediting agencies, as regulators, adopt an accreditation standard requiring that schools implement policies and procedures related to screening faculty candidates to determine if they have been subject to misconduct findings. Such an accreditation standard helps institutions fulfill their mission of providing a safe and healthy environment where students, faculty, and staff can learn, work, and thrive

Language in the context of motor activity: Gross and fine motor differences.

The present study tested a portion of McCabe\u27s (1989) model which predicts that a child\u27s level of motor development may influence speech produced by both parents and child and subsequently the language acquisition style the child will develop. Subjects were eight boys and eight girls, and their mothers. Mothers were given the Motor Skills Domain of the Vineland Behavior Adaptive Scales to measure the child\u27s current motor ability. Two out of three children who were at higher levels of motor development and lower levels of language development used an expressive style of speech. It was suggested that measures other than MLU be used to determine linguistic maturity due to characteristics of the expressive style. Contexts of gross and fine-motor activity were also created to see if different motor activity produces different speech. Context influenced types of speech produced in both mother and child, although not always in accompaniment. When responding to their mothers\u27 speech, children did not respond to object labels to the same degree as their mothers had produced them. Motor development is a contextual influence on language development and children appear to contribute independently to the language-learning context. However, interaction of parent, child, and context appears to be even more subtle and indirect than McCabe\u27s model proposes.Dept. of Psychology.

Developing and Validating the Youth Conduct Problems Scale-Rwanda: A Mixed Methods Approach

This study developed and validated the Youth Conduct Problems Scale-Rwanda (YCPS-R). Qualitative free listing (n = 74) and key informant interviews (n = 47) identified local conduct problems, which were compared to existing standardized conduct problem scales and used to develop the YCPS-R. The YCPS-R was cognitive tested by 12 youth and caregiver participants, and assessed for test-retest and inter-rater reliability in a sample of 64 youth. Finally, a purposive sample of 389 youth and their caregivers were enrolled in a validity study. Validity was assessed by comparing YCPS-R scores to conduct disorder, which was diagnosed with the Mini International Neuropsychiatric Interview for Children, and functional impairment scores on the World Health Organization Disability Assessment Schedule Child Version. ROC analyses assessed the YCPS-R’s ability to discriminate between youth with and without conduct disorder. Qualitative data identified a local presentation of youth conduct problems that did not match previously standardized measures. Therefore, the YCPS-R was developed solely from local conduct problems. Cognitive testing indicated that the YCPS-R was understandable and required little modification. The YCPS-R demonstrated good reliability, construct, criterion, and discriminant validity, and fair classification accuracy. The YCPS-R is a locally-derived measure of Rwandan youth conduct problems that demonstrated good psychometric properties and could be used for further research

Validation of the “World Health Organization Disability Assessment Schedule for Children, WHODAS-Child” in Rwanda

Overview: The World Health Organization Disability Assessment Schedule for children (WHODAS-Child) is a disability assessment instrument based on the WHO's International Classification of Functioning, Disability and Health for children and youth. It is modified from the original adult version specifically for use with children. The aim of this study was to assess the WHODAS-Child structure and metric properties in a community sample of children with and without reported psychosocial problems in rural Rwanda. Methods: The WHODAS-Child was first translated into Kinyarwanda through a detailed committee translation process and back-translation. Cognitive interviewing was used to assess the comprehension of the translated items. Test-retest reliability was assessed in a group of 64 children. The translated WHODAS-Child was then administered to a final sample of 367 children in southern Kayonza district in rural southeastern Rwanda within a larger psychosocial assessment battery. The latent structure was assessed through confirmatory factor analysis. Reliability was evaluated in terms of internal consistency (Cronbach's alpha) and test-retest reliability (Pearson's correlation coefficient). Construct validity was explored by examining convergence between WHODAS-Child scores and mental disorder status, and divergence of WHODAS-Child scores with protective factors and prosocial behaviors. Concordance between parent and child scores was also assessed. Results: The six-factor structure of the WHODAS-Child was confirmed in a population sample of Rwandan children. Test-retest and inter-rater reliability were high (r = .83 and ICC = .88). WHODAS-Child scores were moderately positively correlated with presence of depression (r = .42, p<.001) and post-traumatic stress disorder (r = .31, p<.001) and moderately negatively correlated with prosocial behaviors (r = .47, p<.001). The Kinyarwanda version of the WHODAS-Child was found to be a reliable and acceptable self-report tool for assessment of functional impairment among children largely referred for psychosocial problems in the study district in rural Rwanda. Further research in low-resource settings and with more general populations is recommended

Threshold concentration and random collision determine the growth of the huntingtin inclusion from a stable core

The processes underlying formation and growth of unfolded protein inclusions are relevant to neurodegenerative diseases but poorly characterized in living cells. In S. cerevisiae, inclusions formed by mutant huntingtin (mHtt) have some characteristics of biomolecular condensates but the physical nature and growth mechanisms of inclusion bodies remain unclear. We have probed the relationship between concentration and inclusion growth in vivo and find that growth of mHtt inclusions in living cells is triggered at a cytoplasmic threshold concentration, while reduction in cytoplasmic mHtt causes inclusions to shrink. The growth rate is consistent with incorporation of new material through collision and coalescence. A small remnant of the inclusion is relatively long-lasting, suggesting that it contains a core that is structurally distinct, and which may serve to nucleate it. These observations support a model in which aggregative particles are incorporated by random collision into a phase-separated condensate composed of a particle-rich mixture

Impact of e-cigarette retail displays on attitudes to smoking and vaping in children: an online experimental study

OBJECTIVES: To estimate the impact of electronic cigarette (e-cigarette) retail display exposure on attitudes to smoking and vaping (susceptibility to tobacco smoking and using e-cigarettes, and perceptions of the harms of smoking and e-cigarette use). DESIGN: Between-subjects randomised experiment using a 2 (e-cigarette retail display visibility: high vs low)×2 (proportion of e-cigarette images: 75% vs 25%) factorial design. SETTING: Online via the Qualtrics survey platform. PARTICIPANTS: UK children aged 13-17 years (n=1034), recruited through a research agency. INTERVENTION: Participants viewed 12 images of retail displays that contained e-cigarette display images or unrelated product images. E-cigarette display images were either high or low visibility, based on a conspicuousness score. Participants were randomised to one of four groups, with e-cigarette display visibility and proportion of e-cigarette images, compared with images of unrelated products, manipulated: (1) 75% e-cigarettes, high visibility; (2) 25% e-cigarettes, high visibility; (3) 75% e-cigarettes, low visibility; (4) 25% e-cigarettes, low visibility. MAIN OUTCOME MEASURES: The primary outcome was susceptibility to smoking (among never smokers only). Secondary outcomes were susceptibility to using e-cigarettes (among never vapers only), and perceptions of smoking and e-cigarette harm (all participants). RESULTS: Neither e-cigarette retail display visibility, nor the proportion of e-cigarette images displayed, appeared to influence susceptibility to smoking (visibility: OR=0.84, 95% CI 0.62 to 1.13, p=0.24; proportion: OR=1.34, 95% CI 1.00 to 1.82, p=0.054 (reference: low visibility, not susceptible)).Planned subgroup analyses indicated that exposure to a higher proportion of e-cigarette images increased susceptibility to smoking among children who visited retail stores more regularly (n=524, OR=1.59, 95% CI 1.04 to 2.43, p=0.034), and those who passed the attention check (n=880, OR=1.43, 95% CI 1.03 to 1.98, p=0.031).In addition, neither e-cigarette retail display visibility nor the proportion of e-cigarette images displayed, appeared to influence susceptibility to using e-cigarettes (visibility: OR=1.07, 95% CI 0.80 to 1.43, p=0.65; proportion: OR=1.22, 95% CI 0.91 to 1.64, p=0.18).Greater visibility of e-cigarette retail displays reduced perceived harm of smoking (mean difference (MD)=-0.19, 95% CI -0.34 to -0.04, p=0.016). There was no evidence that the proportion of e-cigarette images displayed had an effect (MD=-0.07, 95% CI -0.22 to 0.09, p=0.40).Perceived harm of e-cigarette use did not appear to be affected by e-cigarette retail display visibility (MD=-0.12, 95% CI -0.28 to 0.05, p=0.16) or by the proportion of e-cigarette images displayed (MD=-0.10, 95% CI -0.26 to 0.07, p=0.24). CONCLUSIONS: There is no evidence in the full sample to suggest that children's susceptibility to smoking is increased by exposure to higher visibility e-cigarette retail displays, or to a higher proportion of e-cigarette images. However, for regular store visitors or those paying more attention, viewing a higher proportion of e-cigarette images increased susceptibility to smoking. In addition, viewing higher visibility e-cigarette images reduced perceived harm of smoking. A review of the current regulatory discrepancy between tobacco and e-cigarette point-of-sale marketing is warranted. TRIAL REGISTRATION NUMBER: ISRCTN18215632

Impact of health warning labels communicating the risk of cancer on alcohol selection: An online experimental study

Background and Aims: Evidence from tobacco research suggests that health warning labels (HWLs) depicting the adverse consequences of consumption change smoking behaviours, with image-and-text (also known as ‘pictorial’ or ‘graphic’) HWLs most effective. There is an absence of evidence concerning the potential impact of HWLs placed on alcohol products on selection of those products. This study aimed to obtain a preliminary assessment of the possible impact of (a) image-and-text (b) text-only and (c) image-only HWLs on selection of alcoholic versus non-alcoholic drinks. DesignA between-subjects randomised experiment with a 2 (image: present vs absent) x 2 (text: present vs absent) factorial design. SettingThe study was conducted on the online survey platform Qualtrics.Participants Participants (n=6024) were adults over the age of 18 who consumed beer or wine regularly (i.e., at least once a week), recruited through a market research agency. Interventions Participants were randomised to one of four groups varying in the HWL displayed on the packaging of alcoholic drinks: i. image-and-text HWL; ii. text-only HWL; iii. image-only HWL; iv. no HWL. HWLs depicted bowel cancer, breast cancer and liver cancer, which were each displayed twice across six alcoholic drinks. Each group viewed six alcoholic and six non-alcoholic drinks and selected one drink that they would like to consume. MeasurementsThe primary outcome was the proportion of participants selecting an alcoholic versus a non-alcoholic drink.FindingsAlcoholic drink selection was lower for all HWL types compared with no HWL (image-and-text: 56%; image-only: 49%; text-only: 61%; no HWL: 77%), with selection lowest for HWLs that included an image. Image-and-text HWLs reduced the odds of selecting an alcoholic drink compared with text-only HWLs (OR = 0.80, 95% CI = 0.69, 0.92), but increased the odds of selecting an alcoholic drink compared with image-only HWLs (OR = 1.34, 95% CI = 1.16, 1.55).ConclusionsHealth warning labels communicating the increased risk of cancers associated with alcohol consumption reduced selection of alcoholic versus non-alcoholic drinks in a hypothetical choice task in an online setting; labels displaying images had the largest effect. Their impact in laboratory and real-world field settings using physical products awaits investigatio

A New Approach to Analyzing Patterns of Collaboration in Co-authorship Networks - Mesoscopic Analysis and Interpretation

This paper focuses on methods to study patterns of collaboration in co-authorship networks at the mesoscopic level. We combine qualitative methods (participant interviews) with quantitative methods (network analysis) and demonstrate the application and value of our approach in a case study comparing three research fields in chemistry. A mesoscopic level of analysis means that in addition to the basic analytic unit of the individual researcher as node in a co-author network, we base our analysis on the observed modular structure of co-author networks. We interpret the clustering of authors into groups as bibliometric footprints of the basic collective units of knowledge production in a research specialty. We find two types of coauthor-linking patterns between author clusters that we interpret as representing two different forms of cooperative behavior, transfer-type connections due to career migrations or one-off services rendered, and stronger, dedicated inter-group collaboration. Hence the generic coauthor network of a research specialty can be understood as the overlay of two distinct types of cooperative networks between groups of authors publishing in a research specialty. We show how our analytic approach exposes field specific differences in the social organization of research.Comment: An earlier version of the paper was presented at ISSI 2009, 14-17 July, Rio de Janeiro, Brazil.
