Study objective: We examine racial and ethnic differences in opioid prescribing and dosing for long bone fractures at emergency department (ED) discharge. Methods: We conducted an electronic health records–based cross-sectional study of adults with long bone fractures who presented to the ED across 22 sites from a health care delivery system (2016 to 2017).

Background: Future Expectation is important for motivation and wellbeing, however drastic life events such as in refugee situations may result in low expectations. This study aims to investigate the prevalence and determinants of low future expectations among Syrian refugees resettled in Sweden. Methods: A random sample of 1215 Syrian refugees resettled in Sweden responded to questionnaire. Weighted analyses and adjusted relative risks were conducted to determine the prevalences and predictors of low future expectations.

Soiling consists of the deposition of contaminants onto photovoltaic (PV) modules or mirrors and tubes of concentrated solar power systems (CSPs). It often results in a drastic reduction of power generation, which potentially renders an installation economically unviable and therefore must be mitigated. On the other hand, the corresponding costs for cleaning can significantly increase the price of energy generated. In this work, the importance of soiling is assessed for the global PV and CSP key markets.

This study empirically examines the effects of school toilet provision on the primary-school attendance rate in Kenya. Using over 4200 school-level observations between 2013 and 2015, the results consistently show that an increase in the school toilet availability per student significantly raises the primary school attendance rate among both boys and girls. Moreover, the effects are larger for girls than for boys, and especially for pubescent girls.

Agricultural wastes are readily available in farming communities and can be utilised for off-grid electrification as an alternative to diesel generators. This work evaluates for the first time the life cycle environmental sustainability of these small-scale systems in the context of Southeast Asia. Rice and coconut residues are considered for direct combustion and gasification, and livestock manure for anaerobic digestion. Overall, anaerobic digestion is the best option for 14 out of 18 impacts estimated through life cycle assessment.

Norway was the first of ten countries to legislate gender quotas for boards of publicly traded firms. There is considerable debate and mixed evidence concerning the implications of female board representation. In this paper, we explain the main sources of biases in the existing literature on the effects of women directors on firm performance and review methods to account for these biases.

Chagas disease, Human African Trypanosomiasis, and schistosomiasis are neglected parasitic diseases for which new treatments are urgently needed. To identify new chemical leads, we screened the 400 compounds of the Open Access Malaria Box against the cysteine proteases, cruzain (Trypanosoma cruzi), rhodesain (Trypanosoma brucei) and SmCB1 (Schistosoma mansoni), which are therapeutic targets for these diseases. Whereas just three hits were observed for SmCB1, 70 compounds inhibited cruzain or rhodesain by at least 50% at 5 μM.

To answer important questions in the fields of monitoring with densitometry, dual-energy X-ray absorptiometry machine cross-calibration, monitoring, spinal cord injury, periprosthetic and orthopedic bone health, transgender medicine, and pediatric bone health, the International Society for Clinical Densitometry (ISCD) held a Position Development Conference from March 20 to 23, 2019. Potential topics requiring guidance were solicited from ISCD members in 2017. Following that, a steering committee selected, prioritized, and grouped topics into Task Forces.

Electricity systems based on renewables have an increasing demand for flexibility. This paper considers the potential of power-to-gas to provide flexibility and enhance system integration of renewables. Existing research on power-to-gas typically analyses the system effects of a predetermined power-to-gas unit without endogenising the investment decision. Moreover, insights related to market and portfolio effects of power-to-gas are rare. To this end this work presents a stochastic electricity market model.
