Abstract

Purpose

The purpose of the paper is to analyse different post-stall models, originally developed for use in wind turbine codes, and extend their use to the propeller performance prediction.

Design/methodology/approach

Different post-stall methods available in the literature were implemented in JBLADE software. JBLADE contains an improved version of Blade Element Momentum theory, and it is appropriate for the design and analysis of different propellers in off-design conditions.

Findings

The preliminary analysis of the results shows that the propeller performance prediction can be improved using these implemented post-stall models. However, there is a lack of accuracy in the performance prediction of some propellers. Further comparisons including distribution of forces along the blade may help to better understand this inaccuracy of the models, and it will be studied in future work.

Originality/value

The work has extended the use of the post-stall models to the propeller performance prediction codes. It is shown that these models can be used to obtain an improved prediction of the propeller’s performance.

Abstract

Purpose

This paper aims to investigate how purchasing organizations implement supplier diversity (SD) initiatives over time.

Design/methodology/approach

A multiple case study approach was conducted. Data were collected through in-depth interviews with participants from purchasing organizations, intermediary organizations and diverse suppliers.

Findings

The research suggests that the SD journey encompasses three different, but interrelated stages before full implementation is achieved: structuring, operation and adaptation. The findings also provide evidence that SD implementation in Brazil is highly influenced by the lack of a consistent knowledge base and the lack of legitimized intermediary organizations.

Research limitations/implications

Using a temporal approach to understand how different practices suggested by the literature have been managed by practitioners over time, this study contributes to the understanding of the path to effective SD implementation and how intra- and interorganizational context influences this journey.

Practical implications

By identifying which practices should be adopted during different phases of SD implementation and proposing ways to overcome some of the inherent challenges, managers can better plan and allocate resources for the adoption of a successful SD initiative.

Social implications

This research demonstrates how organizations can promote diversity and reduce social and economic inequalities by buying from diverse suppliers.

Originality/value

Using a temporal approach, the research empirically investigates how different purchasing organizations have implemented and managed the known practices and dealt with the challenges faced when trying to adopt SD.

Abstract

Purpose: This chapter explores the current hybridization between true crime and nonfiction investigative documentaries on Video on Demand (VOD) platforms. It would seem necessary to distinguish true crime productions from long-form journalistic documentaries in order to avoid confusion between different products that do not pursue the same ends, such as audiovisual products with highly emotive and engaging components versus a journalistic approach to the truth about what happened. Methodology/approach: The analysis is based on the specific theory of true crime developed by Punnett, who provides genuine narrative codes (Justice, Subversive, Geographic, Forensic, Vocative, and Folkloric) for true crime to distinguish it from the formal conventions and social objectives of journalistic documentaries. The case study (El crimen de Alcàsser) was selected because of its potential to drive a detailed and in-depth study on one of the most traumatic crimes in the country’s recent history: the kidnapping, rape, torture, and killing of three teenagers in 1992. Findings: Several scholars have identified journalistic elements in true crime productions in the digital context, adopted in an attempt to distance them from the true crime tradition of appealing to primitive instincts. Although it has been perceived also as a renewed formula for journalism to reach a wide audience and mainstream success, it banishes journalism from its origin and goals: to guarantee the citizenship’s right to be truly informed about crime. In this way, journalistic documentaries inspired by real crimes may play a crucial role in a democratic society, while true crime only exploits the empathy of viewers and places them in the active participation of determining the suspect-protagonist’s guilt as a mode of “clickable” entertainment in the digital culture. Research limitations: This is the first in a series of studies within a broader research project on true crime documentaries released on the VOD platforms in Spain. The findings are, in this case, preliminary. The analysis needs additional testing before its utility can be reasonably determined and a theory about true crime made in Spain could be developed. Originality: First, there is no specific research in the field of true crime in Spain, although crime stories already enjoyed a prominent place in Spain’s conventional TV programming. Second, the Punnett analysis model introduces an interesting way to complement existing theoretical references about the connections between true crime and journalism.

Abstract

Purpose

A growing number of private, voluntary and mandatory sustainability standards have recently emerged. However, supply chain corruption practices as mechanisms to circumvent sustainability standards have also grown and occur regularly. This paper strives to elaborate theory on the intersection of institutional theory, business corruption and the sustainability standards literature by investigating factors that influence the emergence of supply chain corruption practices.

Design/methodology/approach

Based on secondary data, four in-depth case studies of supply chain corruption practices are investigated through the use of adaptive theory and the method of constant comparisons to elaborate theory on this important phenomenon.

Findings

The paper suggests that although sustainability standards can improve supply chain sustainability performance, if they are adopted only symbolically and not substantively, unanticipated outcomes such as supply chain corruption may occur. The study proposes a typology of supply chain corruption practices, further explores the symbolic adoption of sustainability standards in supply chains and proposes the novel construct of “social isomorphism for corruption.” Since focal companies play central roles in leading supply chain corruption practices, we reason that they can also play a pivotal role in preventing supply chain corruption practices by promoting the substantive adoption of sustainability standards across their supply chains.

Originality/value

This paper elaborates theory on the challenging phenomenon of corruption in supply chains by linking the supply chain management literature to the corruption and the sustainability discourses and offers important insights to aid our understanding on the topic. It generates six propositions and four contributions to the sustainable supply chain management theory, practice and policy.

Abstract

This paper analyses the cost efficiency of Italian football clubs using a stochastic frontier model. The frontier estimation confirmed that the model fits the data well with all coefficients correctly signed and in line with the theoretical requirements. Marketing and Sponsorship is taken into account as an explanatory variable and the factors which contributed to these findings, as well as other policy implications, are provided.

Abstract

Using annual mortality rates at the provincial level for men and women, we construct a Gini index to estimate changes in regional health inequalities since 1860 in Spain. We find a long steady decline in health inequality across provinces from 1860 until today, interrupted by World War I and the Spanish Civil War. Over the 40 years of Franco's rule, health inequality stopped its downward trend and rose. Today, regional differences across provinces are at their lowest historical levels.

Abstract

Purpose

Managerial discourses tend to portray work-related mobility practices in a positive light, presenting mobility assignments as a place of stimulus and differentiation. A conception of mobility as an opportunity, may contrast, in specific economies and business settings, with lived personal experiences. This article reports the results of a three-year study, aimed to question how multinational companies (MNCs) located in a small and developing European economy (Portugal) are building talent pools for expatriate assignments. Interaction effects, as proposed by the job demands-resources (JD-R) theory, are considered as lens to understand the interplay of company expatriate policies, willingness profiles and psychological contracts of expatriates. By using a Portuguese sample, the study examines whether prior findings in mature economies and consolidated MNCs can be generalized to less developed international business settings.

Design/methodology/approach

A three-year study, encompassing 24 expatriate cases observed in five multinational firms born or located in Portugal. Two techniques of empirical data collection were used: statistical sources and documental analysis and in-depth interviews. A total of 37 interviews were conducted, both in-person and remotely, of which 13 were with company managers and representatives, and 24 with expatriates (as defined and referred like this by the companies under study).

Findings

Heterogeneous company policies, ranging from juvenile, functionalist to more dynamic and flow-based approaches, are presented as qualifying resources of willingness levels and psychological contracts of expatriates. Observed interaction effects between policies, willingness and psychological contracts, empirically mirrored in three profiles (conformist, protean and disrupted expatriates) suggest that incentive effects (emanating from company policies) and job demand-resource balance, factored as terms of social and economic trade, are non-linear and asymmetric, influencing firm propensity to succeed while using international work to support company expansion goals. As job resources, expatriate policies are presented as operating as pull or push factors: functionalist HR approaches seem to act as push factors generating more conformist or compelled willingness profiles.

Research limitations/implications

Generalization of study's outcomes has limitations. Future studies are encouraged to use comparative and longitudinal research designs. Furthermore, future research should include business expatriates with entry-level positions, and increase the number of interviewees, as results can also be considered as limited by sample size.

Practical implications

It is suggested that further strategic work is needed to present expatriation development value, formally screen and consider willingness level as selection criteria, and enlarge the pool (from internal to external) of candidates, in peripheral economic settings such as Portugal. A shift to more dynamic and job resource-dense policies are suggested as beneficial, as pathway to optimize social and economic value from expatriation assignments and work experiences.

Originality/value

By putting the interplay between macro and micro-level processes into perspective, the study provides empirical evidence on how company expatriate policies have come to promote unforeseen differentiation of employee willingness and psychological contracts at the heart of MNCs. This is particularly relevant in developing economies such as Portugal, challenging the need to build talent pools for international work assignments. Empirical data illustrating company policies interactive effects with different willingness profiles and psychological contracts of expatriates is provided.

Abstract

Purpose

This study aims to analyze the multicultural consumers’ perceptions multicultural consumers’ perceptions of their experience after participating in online cocreation actions in the fashion industry and the behavioral consequences of that experience.

Design/methodology/approach

This research was conducted in Spain and the UK, with 800 active online cocreators, leading to a proposal of a comprehensive model of the cocreation experience and its effects on satisfaction and engagement with the brand and the intention to continue cocreating using a multi-group covariance structural equation model.

Findings

All the proposed hypotheses were confirmed. Cocreation activities influence the cocreation experience, which, in turn, generates a positive effect on the behavioral responses of individuals in terms of satisfaction, engagement and future intentions to continue participating in the brand’s cocreation activities. The cocreation patterns are similar in both countries, leading to a comparable behavioral model across different cultural contexts. The findings conclude with relevant recommendations on how brands can improve their globalization strategies.

Practical implications

The practical utility for a fashion retailer arises from acknowledging the different dimensions of the cocreation experience as mechanisms to develop strategies that foster customer participation, thus enhancing satisfaction, brand engagement and advocacy. The results also advocate for the proposition of similar actions across different markets, given the homogeneity of behaviors, likely through global platforms that facilitate participation from different markets toward the creation of global communities.

Originality/value

The significant contribution of this research lies in the detailed proposal for measuring the cocreation experience and its integration into a comprehensive model of the impact of cocreation on classic behavioral variables. Furthermore, the differential analysis across two countries provides the added value of a multicultural evaluation of the phenomenon.

Abstract

Looks at the 2000 Employment Research Unit Annual Conference held at the University of Cardiff in Wales on 6/7 September 2000. Spotlights the 76 or so presentations within and shows that these are in many, differing, areas across management research from: retail finance; precarious jobs and decisions; methodological lessons from feminism; call centre experience and disability discrimination. These and all points east and west are covered and laid out in a simple, abstract style, including, where applicable, references, endnotes and bibliography in an easy‐to‐follow manner. Summarizes each paper and also gives conclusions where needed, in a comfortable modern format.
