Older adults are relatively more susceptible to impulsive social influence than young adults

People differ in their levels of impulsivity and patience, and these preferences are heavily influenced by others. Previous research suggests that susceptibility to social influence may vary with age, but the mechanisms and whether people are more influenced by patience or impulsivity remain unknown. Here, using a delegated inter-temporal choice task and Bayesian computational models, we tested susceptibility to social influence in young (aged 18–36, N = 76) and older (aged 60–80, N = 78) adults. Participants completed a temporal discounting task and then learnt the preferences of two other people (one more impulsive and one more patient) before making their choices again. We used the signed Kullback-Leibler divergence to quantify the magnitude and direction of social influence. We found that, compared to young adults, older adults were relatively more susceptible to impulsive social influence. Factor analyses showed that older adults with higher self-reported levels of affective empathy and emotional motivation were particularly susceptible to impulsive influence. Importantly, older and young adults showed similar learning accuracy about others’ preferences, and their baseline impulsivity did not differ. Together, these findings suggest highly affectively empathetic and emotionally motivated older adults may be at higher risk for impulsive decisions, due to their susceptibility to social influence

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

"The End of Immortality!" Eternal Life and the Makropulos Debate

Responding to a well-known essay by Bernard Williams, philosophers (and a few theologians) have engaged in what I call “the Makropulos debate,” a debate over whether immortality—“living forever”—would be desirable for beings like us. Lacking a firm conceptual grounding in the religious contexts from which terms such as “immortality” and “eternal life” gain much of their sense, the debate has consisted chiefly in a battle of speculative fantasies. Having presented my four main reasons for this assessment, I examine an alternative and neglected conception, the idea of eternal life as a present possession, derived in large part from Johannine Christianity. Without claiming to argue for the truth of this conception, I present its investigation as exemplifying a conceptually fruitful direction of inquiry into immortality or eternal life, one which takes seriously the religious and ethical surroundings of these concepts

Shifting the Burden of Corporate Taxes Heterogeneity in Direct Wage Incidence

We contribute to the empirical literature on the effective incidence of corporate income taxation. We focus on the so-called direct incidence via the wage bargaining process. Building on the innovative framework of Arulampalam, Devereux and Maffini (2012), we analyze the importance of various dimensions of heterogeneity at the firm-level. In particular, we investigate the distinct effects of (i) firm size, (ii) level of profitability, and (iii) competition intensity across (iv) different economic sectors. Furthermore, we investigate the relative importance of the surrounding institutional setting. To this end, a firm-level within-country approach is pursued separately for two different economies, namely France and the United Kingdom, which can be regarded as polar cases with respect to the relevant features of the wage-setting process. However, in many respects, we find surprisingly similar results for both countries. Thereby, this paper also adds to the literature by providing new insights on the degree to which results from previous single-country studies can possibly be generalized.Die effektive Inzidenz der Körperschaftsteuer ist ein theoretisch wie empirisch kontroverses Thema. Das Paper leistet einen Beitrag zur empirischen Literatur und fokussiert dabei auf die sogenannte direkte Inzidenz über den Lohnverhandlungskanal. Aufbauend auf dem innovativen Ansatz von Arulampalam, Devereux und Maffini (2012) wird die Bedeutung von verschiedenen Dimensionen der Heterogenität auf der Firmenebene analysiert. Konkret wird erforscht, welchen Einfluss (i) Firmengröße, (ii) Profitabilität und (iii) Wettbewerbsintensität in (iv) verschiedenen Branchen auf das Ausmaß ausüben, in dem die Last der Körperschaftsteuer auf die Löhne der Beschäftigten überwälzt wird. Darüber hinaus wird untersucht, welche Relevanz dabei den institutionellen Gegebenheiten der Lohnverhandlungen zukommt. Dazu werden alle Analysen separat für Frankreich und das Vereinigte Königreich vollzogen, deren Volkswirtschaften mit Blick auf Arbeitsmarktinstitutionen als polare Fälle gelten können. Die jeweiligen Ergebnisse für die beiden Länder sind sich jedoch qualitativ wie quantitativ überraschend ähnlich. Insofern gibt die Studie auch einen Hinweis darauf, inwiefern die Ergebnisse aus auf einzelne Länder bezogene Studien zur effektiven Lohninzidenz der Körperschaftsteuer generalisiert werden können

Photoacoustic Imaging for Characterizing Blood Clots and Demyelinated Structures in the Brain

Photoacoustic imaging(PAI) is a relatively new imaging modality with high spatio-temporal resolution, suitable for functional imaging. This work examines the potential of PAI for studying diseases within the brain such as stroke and multiple sclerosis. Blood samples imaged on two different photoacoustic systems were analysed though statistical measures in gray level co-occurrence matrix(GLCM), allowing for the classification of clotted and unclotted blood with high sensitivity and specificity (>95%). Using chromophore spectral demixing, lipid-rich myelin was mapped and examined in rodent models of demyelination. We demonstrated focal oxygen deprivation associated with a rodent model of photothrombotic stroke. GLCM statistics independently showed characteristics of blood clotting in these hypoxic regions. Our results support PAI as an investigative tool for studying rodent models of stroke and MS.M.H.Sc
