Abstract
Purpose
The purpose of this paper is to provide macromechanical insight into the fatigue behaviour of laser sintered parts and to understand the influence of the laser sintered surface structure on this behaviour.
Design/methodology/approach
A background on the technological maturity of manufacturing processes and the demand for structural and aesthetic properties of laser sintered plastic products is given. As the contribution of surface structure on part quality was the focus, laser sintered specimens with and without surface finishes, as well as injection moulded specimens were used. The latter simply served as a comparison and was not intended to qualify injection moulding. The study comprises the determination of short‐term tensile properties, the load increase method for investigating fracture and deformation behaviours, and fatigue crack propagation analysis.
Findings
According to the test results, the contribution of laser sintered surface structures to relevant mechanical properties can be neglected. Under dynamic loading conditions, laser sintered specimens achieved a longer lifetime but showed less deformation capabilities in contrast to injection moulded specimens. In general, laser sintered specimens presented considerable resistance to crack initiation and propagation.
Research limitations/implications
Because of the long‐term approach of the research, the number of tests conducted per lot was limited. Thus, the effects of different process settings and the reproducibility could not be fully analysed.
Practical implications
The studied fatigue behaviour of laser sintered specimens has implications for the functional testing of parts or components, for the product and process design as well as for the general compatibility of laser sintering as a manufacturing technology of end‐customer products.
Originality/value
The value of this paper lies in the better understanding of deformation and fracture behaviours of laser sintered polymers.

Abstract
Activists understand that achieving social reform via advocacy campaigns requires competencies in a wide range of cultural and political venues. However, differences in movement organizations’ identities and subsequent strategy choices often lead to inter-organizational conflict that detracts from achieving the desired reform goals. In this study, the argument is presented that the exchange of resources, such as proficiencies and skills derived from organizational specialization, in combination with strong personal ties between the organizations’ leadership structure, which forge a degree of trust despite ideological differences, will lead to cooperation. To understand when groups engage in strategic resource exchange and inter-organizational cooperation within a particular issue field, several women’s rights action campaigns organized by women’s groups in New Delhi, India are analyzed. The qualitative data utilized in this chapter consist of in-depth interviews with members of several women’s groups as well as organizational documents; thus, enabling a process-tracing approach to support the argument that personal ties drive the formation of informal inter-group coalition building to advance women’s rights in India.

Abstract
Purpose
This paper aims to address two questions: what kinds of benefits are realized from a vendor‐managed inventory (VMI) program (operational, i.e. efficiency related, vs strategic, i.e. sales related) and how the benefits are shared at the dyad level (suppliers vs buyers).
Design/methodology/approach
The paper uses an exploratory multiple case study with data from five operational VMI dyads, evaluating both buyer and supplier perspectives.
Findings
Three empirically grounded patterns of VMI are proposed. Five contextual inhibitors of VMI impacts are suggested.
Research limitations/implications
The framework presented has been generated from a relatively small number of cases. Threats to external validity have been mitigated with case selection from multiple operational contexts and grounding findings in prior literature.
Practical implications
Using the conceptualization, potential VMI adopters can set more realistic and explicit implementation targets. The suggested contextual factors will help to design more appropriate VMI systems.
Originality/value
Past research on VMI can be mainly characterized by modeling/simulation approaches, focus on operational efficiency implications, and concern with impacts to buyers. In contrast, empirical studies on the actual impacts and dyad‐level reasons considering also the strategic (sales related) motivations for implementing VMI are few. This study contributes by suggesting how VMI is in some instances motivated not by bilateral interests to develop a supply chain, but by unilateral interests, with buyers searching for effortless purchasing, and suppliers for a means to lock in and secure sales.

Abstract
Purpose
This paper aims to examine corporate volunteering as a form of social responsibility carried out by companies in relationships with non-governmental organizations (NGOs). Applying the value creation concept, the success of such relationships is based on value created between the focal company, its employees engaging in the volunteer work and the collaborating NGO actors representing the beneficiaries of the volunteer work. However, how to meaningfully engage employees and strategically manage company–NGO relationships in corporate volunteering has received less scholarly attention. The study hence asks the question: How is mutual value created in corporate volunteering collaborations between business organizations and NGOs?
Design/methodology/approach
Two qualitative case studies of company–NGO relationships involved in corporate volunteer programs for social benefit in Poland and Finland are analyzed.
Findings
Corporate volunteering offers value creation opportunities for each of the three actors in the relationships, namely, the company, the NGO and the employees who participate in the volunteer work. Particularly, employment and volunteering relationships appear to be catalysts for the creation of mutual value in the organizational relationship between a company and NGO.
Originality/value
The present study contributes to the current understanding of company–NGO relationships by emphasizing the role of individual employee volunteers in creating relationship-level value. The study adds also to existing research on corporate volunteering by identifying the way value is created in company–NGO relationships within corporate volunteering.

Abstract
The figure of the female revenger has haunted the western imagination as far back as some of the earliest extant texts, most starkly in Euripides' tragedies Hecuba and Medea (c. 430–420 bc). She has tended to take on one of three forms: the scorned woman, the vengeful mother or the victim of physical violence, almost always sexual violence.
This chapter presents an interdisciplinary and transhistorical understanding of the troubling figure of the violent female revenger in her shifting incarnations. The investigation traces conceptual strands through a variety of cultural texts, focusing on specific instances that are both situated historically and simultaneously analysed for the ways in which they reflect recurring priorities and cultural anxieties through the centuries.
After considering key ideas such as revenge and justice and gender and revenge, the chapter looks more closely at the so-called rape-revenge genre, moving from the earliest examples such as I Spit on Your Grave (1978) to more recent films which are considered for the ways they intersect with the global feminist protest movement #MeToo, and other key cultural moments such as the Harvey Weinstein case and the very public trial of the USA Gymnastics national team doctor Larry Nassar: Revenge (2017), The Nightingale (2018) and Promising Young Woman (2020). The chapter draws direct lines of connection between imaginative works, cultural types and stereotypes, and lived reality in order to come to a fuller understanding of the female revenger.

Abstract
Macroeconomics has an important role to play in understanding the forces at work in the world today, and how they can be harnessed to meet national as well as industrial economic goals. Mr. Smith sorts out popular macroeconomic theories into schools, explains their forecasting limitations, and highlights a few public issues where the media and policymakers tend to want answers instead of forecasts.

Abstract
Purpose
The purpose of this paper is to explore servitization in the context of the service supply chain, particularly the effects of the relationship between the subsystem supplier and the end user on the supplier's as well as on the supply chain's ability to provide industrial services. In addition, it aims to present a solution to overcome the challenges of lack of this relationship.
Design/methodology/approach
A case study incorporating an explorative design science approach identifies a theoretically novel and practically relevant problem in the field of service supply chain management. The study combines empirical data collection; systematic conceptualization of means and ends; evaluation of proposed solutions in iterative‐ and action‐oriented cycles; and theoretical explanation of the observed phenomena and outcomes.
Findings
By establishing a triadic operational model with an integrator and end user, the subsystem supplier can servitize within a supply chain in which the end user relationship is controlled by the integrator. This enables the combining of critical service provision capabilities: supplier's maintenance‐related capabilities and integrator's end user access.
Research limitations/implications
Further research is needed to determine the importance of managing the transition to subsystem suppliers in different types of industrial service supply chains. Because these observations and proposals are based on a single case study, the authors cannot draw conclusions as to how they apply to manufacturers in different problem situations.
Practical implications
The paper presents a decision‐making procedure that describes how a subsystem supplier opting for cooperation in the service supply chain can formulate a coherent set of triadic operational models with intermediaries and end users.
Originality/value
The paper shows how servitization takes place on supply chain level.

Abstract
Purpose
The purpose of this paper is to propose a model of small retailers’ new product acceptance criteria using a grounded theory approach in an emerging market, India.
Design/methodology/approach
Empirical research on retailers’ new product acceptance either takes survey design or modeling approach. This study uses grounded theory approach to systematically collect and analyze data to generate a model for the small retailers’ new product acceptance in an emerging market, India. In depth interviews with ten small retailers, five situated in small market town and five in a metro were conducted.
Findings
Retail margin on offer is the first and foremost criteria considered while accepting a new product along with product and market-related factors. The small retailers spelt out the tradeoff decision on retail margins while accepting a new product. The tradeoff criteria that emerged during the analysis are trade and promotional support, sales potential of the product, salesperson relationship with the retailer, aspects of fairness in the relationship, corporate reputation, relevant product information, and availability of the product with other retail competitors.
Practical implications
The study suggests that marketers have to maintain healthy relationship with the channel partners especially the retailers who are in direct contact with the final consumer. The findings of the study suggest that marketers specifically need to take into consideration aspects of fairness and encourage salespersons to build and foster relationships with small retailers.
Originality/value
This study is one of the few study which uses grounded theory approach to propose a retailer’s new product acceptance model.

Abstract
Purpose
Based upon social exchange theory, this study investigates the mediating effect of consumers' trust in banking industry frontline employees on two relationships: (1) the relation between consumers' perceptions of frontline employees' empathy and consumers' perceptions of frontline employees' performance, and (2) the relation between consumers' perception of frontline employees' customer orientation and consumers' perceptions of frontline employees' performance.
Design/methodology/approach
The authors used a time-lag research design to collect data through online questionnaires distributed in two waves. The sample comprises 375 respondents having experience and interaction with banking frontline employees.
Findings
Results confirm the mediating effect of consumers' trust in the banking industry on the relationships between their perceptions of frontline employees' empathy and consumer orientation on the one hand and their perceptions of frontline employees' performance on the other hand.
Practical implications
Results may be helpful to policymakers and managers in the service industries, prompting them to adopt approaches and strategies designed to build strong relationships with consumers, thus increasing consumers' trust and frontline employees' performance.
Originality/value
This study confirms the relevance of social exchange theory in understanding the role of consumers' trust and perceptions of frontline employees' empathy and consumer orientation in understanding their perception of frontline employee performance in the banking industry.
