Multiplicatively separable preferences and output persistence

In the New-Neoclassical Synthesis literature it is customary to use additively separable preferences, very often not compatible with long-run productivity growth and trend inflation. The present paper shows that using multiplicatively separable preferences it is possible to gain further insight on the persistence mechanics of this class of models. In particular it is showed that the more leisure and the money-consumption bundle are Edgeworth complement and the less persistent are output deviations after a monetary shock. The basic intuition for this result is that an increase in money supply not only induces economic agents to increase their labour supply, but also raises the opportunity cost for this choice given that agents with more money in their pockets and greater consumption would like to have more leisure too. In addition, empirical estimates not only support multiplicatively and not additively separable preferences, but highlight new problems for the New-Neoclassical Synthesis given that leisure and money (consumption) appear to be Edgeworth complements and not substitutes

Regional aspects of aggregate profitability dynamics in Italy

We study aggregate profitability dynamics in Italy from 1995 to 2009, by stressing its regional trends. We make use of various analytic approaches, such as decompositions, analysis of the ranking of the profit rate of the various regions and of their coefficient of variation, as well as of a shift-share analysis. We find that the distribution of regional profit rates changed little over time and that aggregate profitability dynamics was driven by within region developments rather than by changes of the weights of the regions within the national economy. Policy and theoretical implications are discussed in the light of the previous literature of reference

Access to electricity and socio-economic characteristics: panel data evidence from 31 countries

The case study literature on access to electricity highlighted a number of socio-economic variables linked to it. The purpose of our research is to check whether these variables also show up in panel data/cross-country regressions and to assess their relative strength. Our results support the widespread belief that electrification plans in developing countries should target rural areas and extensively rely on renewable energy sources. They should also be accompanied by measures fostering human capital accumulation and the involvement of local population. These general results need to be gauged within each country's specific context, carefully considering its own complexities. Therefore, our results complement, rather than substitute the available case study literature

Patient safety culture in Italian out-ofhours primary care service: a national cross-sectional survey study

Background: Out-of-hours (OOH) services in Italy provide >10 million consultations every year. To the authors' knowledge, no data on patient safety culture (PSC) have been reported. Aim: To assess PSC in the Italian OOH setting. Design & setting: National cross-sectional survey using the Safety Attitudes Questionnaire — Ambulatory Version (SAQ-AV). Method: The SAQ-AV was translated into Italian and distributed in a convenience sample of OOH doctors in 2015. Answers were collected anonymously by Qualtrics. Stata (version 14) was used to estimate Cronbach's alpha, perform exploratory and confirmatory factor analysis, correlate items to doctors' characteristics, and to do item descriptive analysis. Results: Overall, 692 OOH doctors were contacted, with a 71% response rate. In the exploratory factor analysis (EFA), four factors were identified: Communication and Safety Climate (14 items); Perceptions of Management (eight items); Workload and Clinical Risk (six items); and Burnout Risk (four items). These four factors accounted for 68% of the total variance (Kaiser-Meyer-Olkin [KMO] statistic = 0.843). Cronbach's alpha ranged from 0.710-0.917. OOH doctors were often dissatisfied with their job; there is insufficient staff to provide optimal care and there is no training or supervision for new personnel and family medicine trainees. Service managers are perceived as distant, with particular issues concerning the communication between managers and OOH doctors. A large proportion of OOH doctors (56.8%) state that they do not receive adequate support. Conclusion: These findings could be useful for informing policies on how to improve PSC in Italian OOH service

Membership duration in a Spanish Union : a survival analysis

This article presents an analysis of the characteristics that are associated with union membership duration using data from the membership registers of the largest Spanish trade union: Comisiones Obreras (CCOO, Workers' Commissions). Making use of survival analysis techniques, the results indicate that the shortest membership durations and the highest risks of leaving are associated with workers with poor employment conditions, mainly youth and foreigners, as well as those in firms, economic sectors, and territories where the union has a rather weak presence. As workers in these situations represent the majority of both current joining and leaving rates, the article concludes that retention policies should focus on the early stages of union membership

The origin of gas in the Extended Narrow Line Region of nearby Seyfert galaxies.I. NGC 7212

The Extended Narrow Line Region (ENLR) of Active Galactic Nuclei (AGN) is a region of highly ionized gas with a size of few up to 15-20 kpc. When it shows a conical or bi-conical shape with the apexes pointing towards the active nucleus, this region is also called ionization cones. The ionization cones are an evidence of the Unified Model that predicts an anisotropic escape of ionizing photons from the nucleus confined to a cone by a dusty torus. Many details about the complex structure of the ENLR still remain unveiled, as for example the origin of the ionized gas. Here we present new results of a study of the physical and kinematical properties of the circumnuclear gas in the nearby Seyfert 2 galaxy NGC 7212. Medium and high resolution integral field spectra and broad-band photometric data were collected and analysed in the frame of an observational campaign of nearby Seyfert galaxies, aiming to handle the complicated issue of the origin of the gas in the ENLR. This work is based on: (i) analysis of gas physical properties (density, temperature and metallicity), (ii) analysis of emission line ratios, and (iii) study of kinematics of gas and stars. By reconstructing the [O III]/Hbeta ionization map, we pointed out for the first time the presence of an ionization cone extended up to about 6 kpc, made by a large amount of low metallicity gas, kinematically disturbed and decoupled from stars, whose highly ionized component shows radial motions at multiple velocities proved by the complex profiles of the specral lines. Since NGC 7212 is a strongly interacting triple galaxy system, the gravitational effects are likely to be at the origin of the ENLR in this Seyfert galaxy.Comment: 13 pages, 21 figures, accepte

Mitochondrial genetic haplogroups and incident obesity: a longitudinal cohort study

BACKGROUND/OBJECTIVES: A small number of case-control studies have suggested that mitochondrial haplogroups could be associated with obesity. We examined whether obesity risk was influenced by mitochondrial haplogroup in a large North American cohort across an 8-year period. We conducted a longitudinal cohort study including individuals from the Osteoarthritis Initiative. SUBJECTS/METHODS: Mitochondrial haplogroups were determined by sequencing and PCR-RFLP techniques using this nomenclature: HV, JT, KU, IWX, and super HV/others. The strength of the association between mitochondrial haplogroups and incident obesity was quantified with hazard ratios (HRs), adjusted for potential confounders using a Cox's regression analysis. RESULTS: Overall, 2342 non-obese Caucasian participants (56.7% women) with a mean ± SD age of 62.0 ± 9.5 years at baseline were included. During a median follow-up of 8 years, 334 individuals ( = 14.3% of baseline population) became obese. After adjusting for nine potential confounders, the haplogroups IWX carried a significant 48% higher risk of obesity (HR = 1.48; 95% CI: 1.02-2.39) compared to the HV haplotype (the most frequent type). CONCLUSION: Only the presence of the IWX haplogroups appears to be linked to increased obesity risk, independent of potential baseline confounders. Future cohort studies are needed to confirm these findings and to determine potential underlying mechanisms

Online patient simulation training to improve clinical reasoning: a feasibility randomised controlled trial

Background Online patient simulations (OPS) are a novel method for teaching clinical reasoning skills to students and could contribute to reducing diagnostic errors. However, little is known about how best to implement and evaluate OPS in medical curricula. The aim of this study was to assess the feasibility, acceptability and potential effects of eCREST — the electronic Clinical Reasoning Educational Simulation Tool. Methods A feasibility randomised controlled trial was conducted with final year undergraduate students from three UK medical schools in academic year 2016/2017 (cohort one) and 2017/2018 (cohort two). Student volunteers were recruited in cohort one via email and on teaching days, and in cohort two eCREST was also integrated into a relevant module in the curriculum. The intervention group received three patient cases and the control group received teaching as usual; allocation ratio was 1:1. Researchers were blind to allocation. Clinical reasoning skills were measured using a survey after 1 week and a patient case after 1 month. Results Across schools, 264 students participated (18.2% of all eligible). Cohort two had greater uptake (183/833, 22%) than cohort one (81/621, 13%). After 1 week, 99/137 (72%) of the intervention and 86/127 (68%) of the control group remained in the study. eCREST improved students’ ability to gather essential information from patients over controls (OR = 1.4; 95% CI 1.1–1.7, n = 148). Of the intervention group, most (80/98, 82%) agreed eCREST helped them to learn clinical reasoning skills. Conclusions eCREST was highly acceptable and improved data gathering skills that could reduce diagnostic errors. Uptake was low but improved when integrated into course delivery. A summative trial is needed to estimate effectiveness

Online interprofessional education related to chronic illness for health professionals : a scoping review

This scoping review focuses on identifying the quantity and quality of research evidence available with regard to online interprofessional education related to chronic disease management. Recent advances have seen the emergence of information communication technology and digital health solutions that may improve monitoring of and self-management of chronic disease. With the growing chronic disease burden globally, and the advancement of information communication technology, digital health solutions may improve chronic disease monitoring and self-management. However, health professionals are slow to utilize this technology in chronic disease management. Online education has the potential to enhance utilization of digital health solutions across interprofessional healthcare teams. This scoping review focuses on online interprofessional education and eLearning strategies used to promote engagement and achievement of learning outcomes between health care professionals in chronic disease management. A systematic search of the literature yielded 3112 papers; 15 studies were included in the review following an independent screening process. The review found very limited research for online interprofessional education related to chronic disease so it is not feasible to comment or draw conclusions in relation to its impact on interprofessional learning, student engagement in education or its impact in practice, services or health outcomes. Research methodology and online eLearning strategies varied across studies, highlighting the need for further rigorous studies that include consistency in online interprofessional education strategies, evaluations and study methods
