Understanding subjective well-being: perspectives from psychology and public health

Background Individual subjective well-being (SWB) is essential for creating and maintaining healthy, productive societies. The literature on SWB is vast and dispersed across multiple disciplines. However, few reviews have summarized the theoretical and empirical tenets of SWB literature across disciplinary boundaries. Methods We cataloged and consolidated SWB-related theories and empirical evidence from the fields of psychology and public health using a combination of online catalogs of scholarly articles and online search engines to retrieve relevant articles. For both theories and determinants/correlates of SWB, PubMed, PsychINFO, and Google Scholar were used to obtain relevant articles. Articles for the review were screened for relevance, varied perspectives, journal impact, geographic location of study, and topicality. A core theme of SWB empirical literature was the identification of SWB determinants/correlates, and over 100 research articles were reviewed and summarized for this review. Results We found that SWB theories can be classified into four groups: fulfillment and engagement theories, personal orientation theories, evaluative theories, and emotional theories. A critical analysis of the conflicts and overlaps between these theories reveals the lack of a coherent theoretical and methodological framework that would make empirical research systematically comparable. We found that determinants/correlates of SWB can be grouped into seven broad categories: basic demographics, socioeconomic status, health and functioning, personality, social support, religion and culture, and geography and infrastructure. However, these are rarely studied consistently or used to test theories. Conclusions The lack of a clear, unifying theoretical basis for categorizing and comparing empirical studies can potentially be overcome using an operationalizable criterion that focuses on the dimension of SWB studied, measure of SWB used, design of the study, study population, and types of determinants and correlates. From our review of the empirical literature on SWB, we found that the seven categories of determinants/correlates identified may potentially be used to improve the link between theory and empirical research, and that the overlap in the determinant/correlates as they relate to multiple theory categories may enable us to test theories in unison. However, doing so in the future would require a conscious effort by researchers in several areas, which are discussed.

Environmental Audit and Environmental Disclosure Quality

In this study we explore the association between environmental audit and the quality of environmental disclosure as measured by voluntary and timely disclosure. Relying on a multiple theory framework and using a sample of 81 French non-financial companies listed on the SBF 120 index covering the six-year period from 2012 to 2017, we found a positive and statistically significant relationship between the level of voluntary disclosure of environmental information and the environmental audit committee, the environmental auditor's BIG 4, debt levels, firm size, earnings management, and the industry. In addition, findings indicate that the environmental audit committee, CSR committee, the environmental auditor's BIG 4, earnings management, firm size, and the industry have an impact on the timely disclosure of environmental information. However, the regression of the results showed that there is no relationship between CSR committee and the level of the voluntary disclosure of environmental disclosure.

Perspectives of the App Economy: Tenets of the Innovative Phenomenon

The paper aims to explore the App Economy drawing on a configurational multiple-theory perspective (Meyer, Tsui & Hinings 1993; Miller, 1996), using the lens of Transaction Costs Theory, Regulation, Disruptive Innovation Theory and Systemic Approach. These theories are examined in the form of tenets. The choice of these theories as dimensions of our model is the output of two different activities. The first regards an ex-ante analysis of the previous studies in this field in order to find less investigated perspectives and find a connection between the topic of the App Economy and the main management theories; the second refers to a debate with some strategic management scholars in order to identify and choice the main theories for this research. This paper contributes to the existing literature by proposing an original interpretation of the App Economy and it tries to add new knowledge in this emerging research field by adding new tenets. The results of study are the formulation of eight different tenets: two for Transaction Costs Theory, one for Regulation, three for Disruptive Innovation Theory and two for Systemic Approach. These results have confirmed the linked between chosen theories and the new research field of the App Economy. In any case, this paper is a preliminary study to develop a theoretically grounded approach to understanding the emergence of the App Economy and how manage the changes that it brings into the markets. This study has implications for several stakeholders (such as managers, enterprises, institutions, Authorities, app developers, operators, platform managers and other organizations that work in this field), and for several industries being impacted by developments induced by this innovative sharing economy.

Factors related to road system organisation and its association with mortality due to motor vehicle-pedestrian collisions in Guadalajara Metropolitan Area

IntroductionTraffic events are one of the five leading causes of mortality in Mexico. Pedestrians are one of the main road users involved in such incidents and have the highest mortality rate, which is regularly analysed in relation to vehicles and pedestrians, but not the built environment. The purpose of this study was to analyse the elements of the road system organisation that influences the mortality rate of pedestrians hit by motor vehicles in the Guadalajara Metropolitan Area.MethodWe designed a case and control study in which the cases were sites where a pedestrian died during 2012. The controls were sites close to where the death occurred, as well as those with road infrastructure characteristics similar to those where the events took place. We obtained the pedestrian data from the death certificates and assessed some of the environmental elements of the road sites. A logistic regression analysis was used to estimate OR; 95% CI.ResultsRoad system factors related with pedestrian mortality in close locations were: the presence of bus stops on intersections in one street or both, and road system features, such as the presence of traffic islands, vehicle flow and pedestrian flow.ConclusionsAccording to the urban network theory and multiple theory, the final elements resulted as risk factors due to a fault in connectivity between the nodes. A temporal analysis of urban features will help urban planners make decisions regarding the safety of pedestrians and other road users.

Russell’s Higher-Order Judgement Relation

This chapter radically redraws the relationship between Russell and Wittgenstein in the 1910s, overturning the orthodox theory that Wittgenstein sunk Russell’s multiple theory of judgement. Starting from 1903, the chapter explains how Russell’s conception of the particular–universal distinction evolved under pressure from both developments in his thinking about the nature of judgement and the nature of relations, concerning the unity of the former and the direction of the latter. This shows that Russell wasn’t overcome by Wittgenstein’s criticisms of his multiple relation theory of judgement in 1913 and that Russell continued to develop the multiple relation theory up until 1919.
