High performance Cuk converter considering non-linear inductors for photovoltaic system applications

The Cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. In addition, current ripple can be more reduced because of two input and output inductors at both sides. This paper presents a new application of current-variable inductors in a Cúk converter that reduces the size and capacity of storage elements. Because of two inductors in structure, implementation of these variable inductors is important; therefore, the proposed design leads to cost and size savings, increases the performance interval of tracker to gain solar energy at lower sunlight levels, and simplifies control strategy. To validate the effectiveness of this structure, the analytical analysis, simulation results using PSCAD/EMTDC software and experimental results are presented

Towards a taxonomy of research misconduct: the case of business school research

This paper examines the growing pressures and incentives encouraging research misconduct, along with the consequences, as illustrated by the case of business school research. Drawing on a review of the literature on different theoretical approaches to analysing organizational misconduct, we develop a formal taxonomy distinguishing appropriate conduct from blatantly inappropriate misconduct but with a specific focus on the ‘grey’ areas between these extremes in the form of questionable and inappropriate behaviour. We identify various sources of research misbehaviour and different categories of those affected. The aim is to provide a clearer understanding of what research behaviour is deemed appropriate or not, which stakeholders it affects, and the pressures and incentives likely to exacerbate such misconduct. We conclude with a discussion of how the taxonomy can help shape future good research practice (thereby setting a better example to students), and offer some propositions for future researc

Manifesto of computational social science

The increasing integration of technology into our lives has created unprecedented volumes of data on society's everyday behaviour. Such data opens up exciting new opportunities to work towards a quantitative understanding of our complex social systems, within the realms of a new discipline known as Computational Social Science. Against a background of financial crises, riots and international epidemics, the urgent need for a greater comprehension of the complexity of our interconnected global society and an ability to apply such insights in policy decisions is clear. This manifesto outlines the objectives of this new scientific direction, considering the challenges involved in it, and the extensive impact on science, technology and society that the success of this endeavour is likely to bring about.The publication of this work was partially supported by the European Union’s Seventh Framework Programme (FP7/2007–2013) under grant agreement No. 284709, a Coordination and Support Action in the Information and Communication Technologies activity area (‘FuturICT’ FET Flagship Pilot Project).

Opening Constructive Dialogues Between Business Ethics Research and the Sociology of Morality: Introduction to the Thematic Symposium

Over the last decade, scholars across the wide spectrum of the discipline of sociology have started to reengage with questions on morality and moral phenomena. The continued wave of research in this field, which has come to be known as the new sociology of morality, is a lively research program that has several common grounds with scholarship in the field of business ethics. The aim of this thematic symposium is to open constructive dialogues between these two areas of study. In this introductory essay, we briefly present the project of the new sociology of morality and discuss its relevance for business ethics. We also review the contributions to this thematic symposium and identify four specific domains where future research can contribute to fruitful dialogues between the two fields. © 2020, Springer Nature B.V

The regulation of morality in formal organizations: the case of Iranian oil industry

Questioning the moral foundations and consequences of formal organizations has become a central concern in organization theory. Despite the extensive research in this broad area, organization scholars have not yet adequately investigated the systematic effects of a formal organization on the morality of its own members, particularly from a process perspective. As a result, today little is known about the internal dynamics of organizations as it treats and influences the morality of organizational members. To address this issue, the present study takes a discursive understanding of morality and explores the intra-organizational processes that regulate the moral discourse of organizational members. The theoretical foundation of this research draws on the literatures of institutional theory and critical management studies, and highlights two domains – practice and privilege – as primary sites of moral regulation in organizations. The question that guides the present study is – what are the common patterns of regulating practice and privilege that characterizes the organizational regulation of morality? This work investigates these patterns in the context of the Iranian oil industry, which has been the largest industry and the main source of national income in Iran for the past century. The oil industry is particularly appropriate and interesting for this study because in the face of several radical changes in the broader moral order of the Iranian society, the organizations of this industry have been able to regulate the morality of their members regarding the issues of concern for their business. The findings suggest that organizations in this industry regulate the morality of their members mainly through four processes: Repositioning, restructuring, reframing, and cooperating/not cooperating. The collected data also points to some of the salient institutional characteristics that underlie the organizational regulation of morality. I discuss the insights that these findings provide for organization research on moral phenomena and highlight the various aspects of the active role of organization in regulating morality. I conclude the thesis with a review of the implications for theoretical understanding of morality and propose directions for future research in this area
