The road not taken: how psychology was removed from economics, and how it might be brought back*

Abstract: This article explores parallels between the debate prompted by Pareto’s reformulation of choice theory at the beginning of the twentieth century and current controversies about the status of behavioural economics. Before Pareto’s reformulation, neoclassical economics was based on theoretical and experimental psychology, as behavioural economics now is. Current discovered preference defences of rational-choice theory echo arguments made by Pareto. Both treat economics as a separate science of rational choice, independent of psychology. Both confront two fundamental problems: to find a defensible definition of the domain of economics, and to justify the assumption that preferences are consistent and stable. One of the most significant developments in economics over the last two decades has been the growth of behavioural economics, which draws on the theoretical and methodological approaches of psychology in explaining economic phenomena. Behavioural economists take pride in grounding their explanations on empirical hypotheses about how human beings really think and act, rather than on deductions from a priori assumptions about rational choice, and in subjecting those hypotheses to experimental test. Viewed in historical perspective, behavioural economists are trying to reverse a fundamental shift in economics which took place from the beginning of the twentieth century: the Paretian turn. This shift, initiated by Vilfredo Pareto and completed in the 1930s and 1940s by John Hicks, Roy Allen and Paul Samuelson, eliminated psychological concepts from economics by basing economic theory on principles of rational choice. From then to the 1980s, almost all the main lines of development in economic theory were aimed at

Rising atmospheric methane: 2007-2014 growth and isotopic shift

Abstract: From 2007 to 2013, the globally averaged mole fraction of methane in the atmosphere increased by 5.7 ± 1.2 ppb yr−1. Simultaneously, δ13CCH4 (a measure of the 13C/12C isotope ratio in methane) has shifted to significantly more negative values since 2007. Growth was extreme in 2014, at 12.5 ± 0.4 ppb, with a further shift to more negative values being observed at most latitudes. The isotopic evidence presented here suggests that the methane rise was dominated by significant increases in biogenic methane emissions, particularly in the tropics, for example, from expansion of tropical wetlands in years with strongly positive rainfall anomalies or emissions from increased agricultural sources such as ruminants and rice paddies. Changes in the removal rate of methane by the OH radical have not been seen in other tracers of atmospheric chemistry and do not appear to explain short-term variations in methane. Fossil fuel emissions may also have grown, but the sustained shift to more 13C-depleted values and its significant interannual variability, and the tropical and Southern Hemisphere loci of post-2007 growth, both indicate that fossil fuel emissions have not been the dominant factor driving the increase. A major cause of increased tropical wetland and tropical agricultural methane emissions, the likely major contributors to growth, may be their responses to meteorological change.

A Pyrenyl-Appended Triazole-Based Calix[4]arene as a Fluorescent Sensor for Cd2+ and Zn2+

Abstract: The synthesis and evaluation of a novel calix[4]arene-based fluorescent chemosensor 8 for the detection of Cd(2+) and Zn(2+) is described. The fluorescent spectra changes observed upon addition of various metal ions show that 8 is highly selective for Cd(2+) and Zn(2+) over other metal ions. Addition of Cd(2+) and Zn(2+) to the solution of 8 results in ratiometric measurement.

Role and outcomes of community health workers in HIV care in sub-Saharan Africa: a systematic review

Abstract: Introduction: The provision of HIV treatment and care in sub-Saharan Africa faces multiple challenges, including weak health systems and attrition of trained health workers. One potential response to overcome these challenges has been to engage community health workers (CHWs). Methodology: A systematic literature search for quantitative and qualitative studies describing the role and outcomes of CHWs in HIV care between inception and December 2012 in sub-Saharan Africa was performed in the following databases: PubMed, PsychINFO, Embase, Web of Science, JSTOR, WHOLIS, Google Scholar and SAGE journals online. Bibliographies of included articles were also searched. A narrative synthesis approach was used to analyze common emerging themes on the role and outcomes of CHWs in HIV care in sub-Saharan Africa. Results: In total, 21 studies met the inclusion criteria, documenting a range of tasks performed by CHWs.These included patient support (counselling, home-based care, education, adherence support and livelihood support) and health service support (screening, referral and health service organization and surveillance). CHWs were reported to enhance the reach, uptake and quality of HIV services, as well as the dignity, quality of life and retention in care of people living with HIV.The presence of CHWs in clinics was reported to reduce waiting times, streamline patient flow and reduce the workload of health workers. Clinical outcomes appeared not to be compromised, with no differences in virologic failure and mortality comparing patients under community-based and those under facility-based care. Despite these benefits, CHWs faced challenges related to lack of recognition, remuneration and involvement in decision making. Conclusions: CHWs can clearly contribute to HIV services delivery and strengthen human resource capacity in sub-Saharan Africa. For their contribution to be sustained, CHWs need to be recognized, remunerated and integrated in wider health systems. Further research focusing on comparative costs of CHW interventions and successful models for mainstreaming CHWs into wider health systems is needed.

Pay-for-performance in the United Kingdom: impact of the quality and outcomes framework: a systematic review.

Abstract: PURPOSE Primary care practices in the United Kingdom have received substan- tial fi nancial rewards for achieving standards set out in the Quality and Outcomes Framework since April 2004. This article reviews the growing evidence for the impact of the framework on the quality of primary medical care. METHODS Five hundred seventy-fi ve articles were identifi ed by searching the MEDLINE, EMBASE, and PsycINFO databases, and from the reference lists of published reviews and articles. One hundred twenty-four relevant articles were assessed using a modifi ed Downs and Black rating scale for 110 observational studies and a Critical Appraisal Skills Programme rating scale for 14 qualitative studies. Ninety-four studies were included in the review. RESULTS Quality of care for incentivized conditions during the fi rst year of the framework improved at a faster rate than the preintervention trend and subse- quently returned to prior rates of improvement. There were modest cost-effective reductions in mortality and hospital admissions in some domains. Differences in performance narrowed in deprived areas compared with nondeprived areas. Achievement for conditions outside the framework was lower initially and has worsened in relative terms since inception. Some doctors reported improved data recording and teamwork, and nurses enhanced specialist skills. Both groups believed that the person-centeredness of consultations and continuity were nega- tively affected. Patients' satisfaction with continuity declined, with little change in other domains of patient experience. CONCLUSIONS Observed improvements in quality of care for chronic diseases in the framework were modest, and the impact on costs, professional behavior, and patient experience remains uncertain. Further research is needed into how to improve quality across different domains, while minimizing costs and any unin- tended adverse effects of payment for performance schemes. Health care organi- zations should remain cautious about the benefi ts of similar schemes.
