Putting sustainable supply chain management into base of the pyramid research

Abstract: Purpose – The aim of this paper is to analyze which sustainable supply chain management (SSCM) arguments are addressed in the base of the pyramid (BoP)-related research. BoP projects address how companies contribute to fulfilling the needs of the poorest populations; increasingly, academics are applying theory to explain these projects. The need for integrating the BoP population into value-adding activities is widely acknowledged, but this is not yet reflected in supply chain management (SCM)-related concepts. The links to SSCM are frequently mentioned but in a scattered manner. Design/methodology/approach – The paper presents a structured literature review of BoP papers published between 2000 and 2014 in peer-reviewed, English-speaking journals available on Web of Science. A content analysis of BoP papers is conducted based on SSCM constructs from the framework presented by Beske and Seuring (2014). Findings – The frequencies of SSCM constructs identified in the BoP papers indicate the prevalence of SSC...

Green supply chain management in food retailing: survey-based evidence in Croatia

Abstract: Green supply chain management (GSCM) research is so far dominated by studies focusing on manufacturing companies, while research on retailers is missing The purpose of this study is to assess the interaction between green in-store activities (environment-related infrastructure and retail in-store processes), GSCM and environmental and economic performance outcomes,The paper builds on empirical evidence gathered from 190 responses by Croatian food retailers to a self-administered survey The identified relationships in the conceptual model are tested using partial least squares structural equation modeling,The results reveal a positive relation between green in-store activities and GSCM in food retailing regarding environmental and economic performance The relevance of these relationships accrues from the positive association between GSCM and food retailers’ environmental performance, which in turn drives economic performance It is noteworthy that green supply chain practices drive environmental and then also economic performance,The study extends the application of GSCM to retailing and, therefore, broadens its scope However, the data collected are based on one country and, thus, should be extended to assess the impact of green retailing practices in the supply chain on environmental and economic performance in other countries,This study, to the best of the authors’ knowledge, is the first empirical analysis on the relationship between green in-store activities and GSCM in the context of food retail This important link to customers has rarely been explored Further, the representative sample of food retailers in Croatia is unique as generally data from Central and Eastern European countries are still rare Finally, the operationalization of GSCM practices into three constructs as green logistics, green purchasing and cooperation with suppliers’ offers conceptual contributions to the GSCM field

Entrepreneurial ecosystems: a systematic review

Abstract: Purpose The literature on entrepreneurial ecosystems is fragmented, and yet, no studies have paid attention to integrating the available studies. The purpose of this study is to provide a systematic review of contributions related to entrepreneurial ecosystems. Design/methodology/approach This literature review evaluates studies that are covered in the Web of Science index. Findings In addition to the recent state of research (covering industries, geographical scopes, methodologies, etc.), this study provides an extension of Isenberg’s (2011) model of entrepreneurial ecosystems. Research limitations/implications A new avenue arises for both conceptual and empirical research by emphasizing crowdsourcing as a contributing element for the entrepreneurial ecosystem. Future studies can evaluate the effectiveness of different types of crowdsourcing profoundly to make sure whether creating a promising ecosystem all types of crowdsourcing have a similar value or impact. Practical implications For public policy and local decision-makers, both collaboration opportunities and interaction interfaces between the stakeholders of the entrepreneurial need to be reconsidered in the design of entrepreneurial ecosystems. Social implications Higher degrees of collaboration, information exchange and innovation are likely to yield favorable entrepreneurship environments. Originality/value Novelty of this study arises from integrating crowdsourcing theory in the systematic review of entrepreneurial ecosystems.

Contemporary marketing practices in Russia

Abstract: Purpose – This study investigates the validity of the relationship paradigm in contrast with the marketing‐mix paradigm with respect to modern Russian markets. Moreover, the specifics of Russian marketing practices are outlined and a comparison with marketing practices in other countries is provided.Design/methodology/approach – The paper is rooted in the theoretical framework of the “Contemporary Marketing Practices” project. Data about marketing practices are gathered with standardised questionnaires and groups of organisations are identified using cluster analysis, the gap criterion, and canonical discriminant analysis. By comparing scores for relational marketing as well as transactional marketing, the marketing practices are described and contrasted with those in Argentina and Canada. To assess the success of different combinations of marketing activities, association rules are computed.Findings – Contemporary Russian marketing practices cover only a narrow spectrum of the diversity of marketing prac...

Power, approach, and inhibition. Власть, напористость и подавленность

Abstract: Статья посвящена вопросам влияния власти на поведение человека. Авторы рассматривают данные различных источников, в которых увеличение власти связывается с напористостью, а ее уменьшение - с подавленностью. Конкретно, власть ассоциируется с: а) позитивным аффектом; б) вниманием к вознаграждению и к свойствам других, удовлетворяющим личные цели; в) автоматической переработкой информации и резкими суждениями; г) расторможенным социальным поведением. Уменьшение власти, напротив, ассоциируется с: а) негативным аффектом; б) вниманием к угрозам и наказаниям, к интересам других и к тем характеристикам я, которые отвечают целям других; в) контролируемой переработкой информации и совещательным типом рассуждений; г) подавленным социальным поведением. Обсуждаются также последствия этих паттернов поведения, связанных с властью, и потенциальные модераторы.
