Popularity

What makes you popular among your high-school peers? And what are the labor market returns to popularity? We investigate these questions using an objective measure of popularity derived from sociometric theory: the number of friendship nom- inations received from schoolmates. We provide novel evidence that early family en- vironment, school composition and school size play a signicant role in determining popularity. We show that the estimated wage return to one additional nomination is about 2 percent the popularity premium. This amounts to roughly 40 percent of the return to one more year of education.

Optimal Charging Strategy for EVs with Batteries at Different States of Health

The electric vehicle (EV) is targeted as an efficient method of decreasing CO2 emission and reducing dependence on fossil fuel. Compared with filling up the internal combustion engine (ICE) vehicle, the EV power charging time is usually long. However,to the best of our knowledge, the current charging strategy does not consider the battery state of health (SOH). It is noted that a high charging current rate may damage the battery life. Motivated by this, an optimal charging strategy is proposed in the present paper, providing several optimal charging options taking into account the EV battery health, trying to prevent ‘abused battery utilization’ happening

If you're happy and you know it, clap your hands! Survey design and the analysis of satisfaction

Surveys differ in the way they measure satisfaction and happiness, so comparative research findings are vulnerable to distortion by survey design differences. We examine this using the British Household Panel Survey, exploiting its changes in question design and parallel use of different interview modes. We find significant biases in econometric results, particularly for gender differences in attitudes to the wage and hours of work. Results suggest that the common empirical finding that women care less than men about their wage and more about their hours may be an artifact of survey design rather than a real behavioural difference

Checklist for One Health Epidemiological Reporting of Evidence (COHERE).

One Health is defined as the intersection and integration of knowledge regarding humans, animals, and the environment, yet as the One Health scientific literature expands, there is considerable heterogeneity of approach and quality of reporting in One Health studies. In addition, many researchers who publish such studies do not include or integrate data from all three domains of human, animal, and environmental health. This points to a critical need to unify guidelines for One Health studies. This report details the Checklist for One Health Epidemiological Reporting of Evidence (COHERE) to guide the design and publication format of future One Health studies. COHERE was developed by a core writing team and international expert review group that represents multiple disciplines, including human medicine, veterinary medicine, public health, allied professionals, clinical laboratory science, epidemiology, the social sciences, ecohealth and environmental health. The twin aims of the COHERE standards are to 1) improve the quality of reporting of observational or interventional epidemiological studies that collect and integrate data from humans, animals and/or vectors, and their environments; and 2) promote the concept that One Health studies should integrate knowledge from these three domains. The 19 standards in the COHERE checklist address descriptions of human populations, animal populations, environmental assessment, spatial and temporal relationships of data from the three domains, integration of analyses and interpretation, and inclusion of expertise in the research team from disciplines related to human health, animal health, and environmental health

Conceptualising specialist supportive clinical management (SSCM) : current evidence and future directions

Background: Current evidence-based treatments for adult anorexia nervosa (AN) have limitations, with high attrition, very poor outcomes for 20% of people, and no clearly superior manualised therapy for adults with AN. Specialist Supportive Clinical Management (SSCM) was designed as a control treatment but has evolved as a valid first line treatment. The present paper aims to provide an overview of the evidence base for SSCM and a pedagogical reconceptualization with expansion by theoretical integration (TI). Body: A secondary meta-analysis endorses SSCM as a promising treatment. This paper positions SSCM as a manualised therapy for adult AN with six unique features, namely (1) a philosophy which is person-centred, non-prescriptive, and informed by the person’s strengths and values, (2) a focus on the person through inclusion of supportive psychotherapy and problem (clinical management), within target symptoms as defined in relation to AN, (3) a flexible and responsive therapy that could be delivered by a variety of clinicians with experience treating AN (4) a commitment to reversing starvation though a directional approach and a defined yet flexible stance on dietetic intervention (5) a commitment to the therapeutic relationship within all three phases of treatment, and (6) a therapy ‘uncluttered’ by specific mandates. In addition, this paper positions SSCM as a treatment that may be strengthened by other modalities and may also be adapted to the treatment of other eating disorders (ED), not just AN. The level of therapist sophistication to deliver upon the supportive psychotherapy component is explored and future directions are offered. Conclusion: SSCM is a unique and valid first line treatment for AN and would benefit from further expansion in line with emerging understandings of AN to strengthen it as a treatment. Speculation on aspects of potency would benefit from further testing. The proposed re-conceptualisation of SSCM in the context of its evidence may strengthen it as a treatment overall, position it as adaptable for treatment of other eating disorders and make it more accessible to clinicians

Optical/IR from ground

The following subject areas are included: research environment; science opportunities; technical development of the 1980's and opportunities for the 1990's; and ground-based O/IR astronomy outside the U.S. Recommendations are presented for: (1) large scale programs (Priority 1: a coordinated program for large O/IR telescopes); (2) medium scale programs (Priority 1: a coordinated program for high angular resolution; Priority 2: a new generation of 4-m class telescopes); (3) small scale programs (Priority 1: near-IR and optical all-sky surveys; Priority 2: a National Astrometric Facility); and (4) infrastructure issues (develop, purchase, and distribute optical CCDs and infrared arrays; a program to support large optics technology; a new generation of large filled aperture telescopes; a program to archive and disseminate astronomical databases; and a program for training new instrumentalists

The Long-Term Impacts of an Integrated Care Programme on Hospital Utilisation among Older Adults in the South of England: A Synthetic Control Study

Introduction: Reducing hospital use is often viewed as a possible positive consequence of introducing integrated care (IC). We investigated the impact of an IC programme in North East Hampshire and Farnham (NEHF), in southern England, on hospital utilisation among older adults over a 55 months period. Method: We used a Generalised Synthetic Control design to investigate the effect of implementing IC in NEHF between 2015 and 2020. For a range of hospital use outcomes, we estimated the trajectory that each would have followed in the absence of IC and compared it with the actual trajectory to estimate the potential impact of IC. Results: Three years into the programme, emergency admission rates started reducing in NEHF relative to its synthetic control, particularly those resulting in overnight hospital stays. By year 5 of the study overall emergency admission rates were 9.8% lower (95% confidence interval: –17.2% to –0.6%). We found no sustained difference in rates of emergency department (ED) visits, and average length of hospital stay was significantly higher from year 2. Conclusion: An IC programme in NEHF led to lower than estimated emergency admission rates; however, the interpretation of the impact of IC on admissions is complicated as lower rates did not appear until three years into the programme and the reliability of the synthetic control weakens over a long time horizon. There was no sustained change in ED visit rates
