This paper aims to identify the potential conflicts that arise between the actual and the revealed preference of a panel of wine judges when the panel’s evaluation is derived by a linear aggregation of individual scores.

A standard axiomatic social choice theoretical model is used to derive and examine the findings.

The findings show that even with the application of a simple majority rule over the pairwise ranking of wines, preferences may be misrepresented by the ordinal ranking of the wine score aggregation.

A number of wine competitions and reviews, to date, use some form of linear aggregation to represent group preferences. Furthermore, tests surrounding wine judge performance are largely dependent on some underlying true measures usually derived from a linear aggregation. The results imply that care should be taken in these regards.

The aim of this paper is to investigate how social exchanges modify the relationship between psychological contract breach and work performance. It aims to present two concurrent hypotheses, based on theoretical interaction effects of social exchanges (conceptualized as social exchange relationships, POS, and trust).

Data were collected from a sample of 266 employees in a service sector company in the USA. Regression analysis was used to explore the moderating effects of social exchanges on the relationships between psychological contract breach and work performance (operationalized as in‐role behaviors and organizational citizenship behaviors).

It was found that the negative relationship between psychological contract breach and work performance was moderated by social exchanges, such that the relationship was stronger for employees with high social exchange relationship, perceived organizational support, and trust.

The data were collected cross‐sectionally, and thus causal inferences have to be made with caution. Moreover, the data were collected from a single source. The study shows that the relations between contract breach and outcomes are moderated by the existing relationship between employee and organization.

Although organizations may invest in long‐term relationships with their employees, psychological contract breaches have a profound impact on work performance. Therefore, organizations should diminish perceptions of contract breach; for instance by providing realistic expectations.

The paper provides new theoretical insights on how social exchange can have two distinct effects on the breach‐outcomes relations. It shows that social exchanges moderate the relations between contract breach and work performance.

The purpose of the research is to investigate whether corporate social responsibility awareness (pCSR), environmental concerns (EC) and consumer environmental knowledge (CK) will have an impact on sustainable purchase intention (SPI). Furthermore, this paper also contributes to surveying the mediating impact of consumer attitudes (CAs) between intention and the three factors mentioned above.

SmartPLS (version 4.0) structural equation modeling (SEM) and quantitative methods were used to analyze 457 responses from consumers. The survey sample consisted of individuals between the ages of 18 and 34, with a male-to-female ratio of 70 to 30. The study aims to examine and put into practice new directions for manufacturing firms in the fields of fashion, food and consumer products. At the same time, provide more convincing evidence about the use of these fields in the research.

The study showed a favorable link between pCSR, EC, CK and SPI through the proposed hypotheses. The research additionally showed that CAs mediate between the aforementioned variables.

The important and distinctive results of this study encourage both consumers and enterprises to make changes in their perceptions of society. Consumers should gradually change their daily lifestyle by consuming more sustainable products. As a result, this outcome will provide the impetus for manufacturing businesses to alter their operational procedures in order to support the shift from the production of products to more friendly processes, with the help of all levels of management within the business.

This articles provides a managerial framework to examine and analyse factors that may influence government decision making in less developed countries. In order to market successfully to these buyers, a series of hurdles has to be cleared. These include meeting eligibility, following procedures, establishing critical linkages, developing competitive offers and exerting appropriate influence. International firms can enhance their success and profits by taking a serious, long‐term approach to these markets.

New York City’s status as a majority “minority” city is reflected in many local neighborhoods that exemplify the racial and ethnic diversity of the urban landscape in the 21st century. In this quintessential immigrant city, the relative share of foreign-born has reached levels not seen since the historic immigrant wave at the turn of the last century (Foner, 2000; Scott, 2002). While “all the nations under heaven” are represented among old and new New Yorkers, researchers find that patterns of residential segregation persist and in fact, have worsened especially for African Americans (Beveridge, 2001; Logan, 2001). The racial balkanization of New York City, however, is tempered by the expansion of “polyethnic” or “global” neighborhoods. These racially and ethnically diverse neighborhoods are found throughout New York City but their concentration in the borough of Queens is notable. Moreover, the magnitude of ethnic diversity in these neighborhoods has “no parallel in previous waves of immigration” (Foner, 2000, p. 58).

The purpose of this paper is to explore the barriers to coordination in humanitarian supply chain management (HSCM), proposes solutions and prioritizes them to overcome the barriers particularly in the Indian context.

This study adopts a comprehensive and rigorous procedure to explore the barriers and solutions to coordination in HSCM. The research design is divided into three phases; first, the barriers and solutions are collected through an extensive literature review; second, barriers and solutions were verified with experts involved in relief operations of the disaster that occurred in Uttarakhand (a Northern state in India) on June 14, 2013 and finally, based on the weight of barriers estimated by fuzzy analytic hierarchy process, solutions to overcome the barriers are prioritized using fuzzy technique for order performance by similarity to ideal solution that considers uncertainty and impreciseness rather than a crisp value.

This study explored 23 barriers to coordination in HSCM and grouped into five categories i.e., strategic barriers, individual barriers, organizational barriers, technological barriers and cultural barriers, and finally 15 solutions were proposed and prioritized to overcome the barriers so decision makers can focus on overcoming these barriers and realize the benefits of coordination in HSCM.

This study provides a more efficient, effective, robust and systematic way to overcome barriers to coordination and improve the competencies of humanitarian supply chain (HSC).

This is the first kind of study that prioritizes the solutions to enhance coordination in HSC based on the weight of the barriers.

This study investigates the mediating role of organizational change capacity (OCC) in the relationship between the perception of extreme contexts and firm product and process innovation, which was not empirically investigated in the literature. In addition, this study explores the moderating role of the perception of extreme contexts-related variables, which were not operationalized in ordinary firms, on the relationship between OCC and firm product and process innovation.

A questionnaire-based research was conducted to test the suggested hypotheses. The data were gathered from 90 firms during the peak period of COVID-19.

This study shows that OCC, which covers contexts, process and learning dimensions, fully mediates the relationship between the perception of extreme contexts and firm product and process innovation. Also, this study discovers that the perception of extreme contexts, including temporal ordering of extremity, the magnitude of consequences, proximity among people and operational deficiencies, positively moderate the relationship between OCC and firm product innovation.

This study has constraints inherited in survey design, primarily sampling and country context.

This study identifies, conceptualizes and operationalizes the term extreme context, conceptually argued for particular organizations/units in ordinary/mundane organization settings so far. In addition, this study extends the current understanding of how the perception of extreme contexts interacts with a firm's capability to increase innovation efforts. Further, this study shows how OCC mediates the relationship between extreme contexts and firm product and process innovation.
