    Aggregate Price Effects of Institutional Trading: A Study of Mutual Fund Flow and Market Returns

    We study the relation between market returns and aggregate flow into U.S. equity funds, using daily flow data. The concurrent daily relation is positive. Our tests show that this concurrent relation reflects flow and institutional trading affecting returns. This daily relation is similar in magnitude to the price impact reported for an individual institution's trades in a stock. Aggregate flow also follows market returns with a one-day lag. The lagged response of flow suggests either a common response of both returns and flow to new information, or positive feedback trading.

    Retention in statutory social work from fast-track child and family programs

    Summary: Two fast-track child and family social work training programs have been established in England — Step Up to Social Work and Frontline. Trainees’ financial support is far higher than for mainstream social work degrees. One of the reasons claimed for setting up these programs is addressing retention, although critics (of Frontline) predicted graduates would not stay in social work. A 4-year study assessed retention and reasons for leaving social work. Attrition rates from statutory social work were calculated from responses (n = 2543) to annual surveys, plus looking up non-respondents in the professional register. Interviews were conducted with fast-track graduates (n = 80) and employers (n = 29). Findings: The overall rate of social work graduates not in statutory social work at 18 months post-qualification was 12% for fast-track programs, and Higher Education Statistics Agency survey data show attrition at 15 months post-qualification as 18% for all social work routes. Frontline's original national recruitment approach was less successful for retention than Step Up to Social Work's regional approach. Perceived local authority support and intrinsic job satisfaction were associated with attrition in longitudinal bivariate analysis. Fast-track graduates leaving statutory social work typically moved to work in social care (including policy roles), health, or education. Applications: Early-career attrition appears to be somewhat lower from fast-track programs than from all social work graduates. Longer-term comparison is not yet possible. In promoting retention, employers should be aware of the importance of staff perceptions of the local authority as supportive, and of their intrinsic job satisfaction

    A New High-Resolution Map of World Mountains and an Online Tool for Visualizing and Comparing

    Answers to the seemingly straightforward questions “what is a mountain?” and “where are the mountains of the world?” are in fact quite complex, and there have been few attempts to map the mountains of the earth in a consistent and rigorous fashion. However, knowing exactly where mountain ecosystems are distributed on the planet is a precursor to conserving them, as called for in Sustainable Development Goals 6 and 15 of the United Nations 2030 Agenda for Sustainable Development. In this article we first compare 3 characterizations of global mountain distributions, including a new, high-resolution (250 m) map of global mountains derived from terrain characteristics. We show how differences in conceptual definition, methodology, and spatial resolution of source data can result in differences in the extent and location of lands classed as mountains. For example, the new 250-m resource documents a larger global mountain extent than previous characterizations, although it excludes plateaus, hilly forelands, and other landforms that are often considered part of mountain areas. We then introduce the Global Mountain Explorer, a new web-based application specifically developed for exploration, visualization, and comparison of these maps. This new open-access tool is an intuitive and versatile resource suitable for a broad range of users and applications

    Effects of High Flavanol Dark Chocolate on Cardiovascular Function and Platelet Aggregation.

    Regular consumption of chocolate and cocoa products has been linked to reduced cardiovascular mortality. This study compared the effects of high flavanol dark chocolate (HFDC; 1064mg flavanols/day for 6 weeks) and low flavanol dark chocolate (LFDC; 88mg flavanols/day for 6 weeks) on blood pressure, heart rate, vascular function and platelet aggregation in men with pre-hypertension or mild hypertension. Vascular function was assessed by pulse wave analysis using radial artery applanation tonometry in combination with inhaled salbutamol (0.4 mg) to assess changes due to endothelium-dependent vasodilatation. HFDC did not significantly reduce blood pressure compared to baseline or LFDC. Heart rate was increased by LFDC compared to baseline, but not by HFDC. Vascular responses to salbutamol tended to be greater after HFDC. Platelet aggregation induced by collagen or the thromboxane analogue U46619 was unchanged after LFDC or HFDC, whereas both chocolates reduced responses to ADP and the thrombin receptor activator peptide, SFLLRNamide (TRAP6), relative to baseline. Pre-incubation of platelets with theobromine also attenuated platelet aggregation induced by ADP or TRAP6. We conclude that consumption of HFDC confers modest improvements in cardiovascular function. Platelet aggregation is modulated by a flavanol-independent mechanism that is likely due to theobromine.This study was supported by a grant (to R. Corder) from Barry Callebaut Belgium N
