Abstract
Purpose
The purpose of this study is to highlight a key strategic initiative within the former ADC Company (now part of TE Connectivity) called “Lean Pull Replenishment”, designed and implemented to achieve Six Sigma customer service excellence. This case study would also help facilitate problem‐based learning pedagogy.
Design/methodology/approach
The study showcases implementation of the Lean Pull Replenishment approach using the define, measure, analyze, improve and control (DMAIC) framework. Key input variables were analyzed that contributed to historically inconsistent and unsatisfactory customer delivery performance. Analysis resulted in improving the allocative efficiency of critical input variables through pilot programs on strategic value streams by deploying dozens of kaizen events, and sustaining the gains through leveraging best practices and effective change management principles.
Findings
The study presents a strong case for the team work and the cultural transformation that occurred during the course of implementing this initiative across ADC supply chain. The paper also summarizes the improvement in customer service metrics and financials of the company.
Originality/value
Through this study, it has been established that with consistency of purpose, using the right tools for solving problems and through teaching Lean principles, remarkable results can be achieved, which can be sustained for the long‐term and become a self‐sustaining business philosophy.

Abstract
Purpose
This paper aims to determine the extent to which graduate student funding portfolios vary across and within engineering, life sciences and physical sciences academic fields for degree recipients. “Graduate student funding portfolios” refers to the percentages of students funded by fellowships, research assistantships, teaching assistantships, personal means and other sources within an organizational unit.
Design/methodology/approach
Using data from the Survey of Earned Doctorates data set, the authors analyze doctoral students’ self-reported primary mechanisms of funding across and within academic fields varying along the Biglan taxonomy. The authors used cluster analyses and logistic regression to investigate within-field variation in funding portfolios.
Findings
The authors show significant differences in doctoral student funding portfolios across dimensions of the Biglan taxonomy characterizing academic fields. Within those fields, the authors demonstrate considerable variation in funding; institutions cluster into different “modes” of funding portfolios that do not necessarily map onto institutional type or control variables.
Originality/value
Despite tremendous investment in graduate students, there has been little research that can help characterize at the program-level how graduate students are funded, either by internal or external mechanisms. As programs continue to feel the pressures of more limited resources coupled with increasing graduate enrollment demands, investigating graduate student funding at a macro level is becoming increasingly important so programs may better understand constraints and predict shifts in resource availability.

Abstract
Purpose
The purpose of this study is to better understand the nature of graduate training experiences in research groups and to identify factors that may lead to increased student retention and success.
Design/methodology/approach
Surveys administered at four US universities resulted in quantitative responses from 130 Master’s and 702 doctoral engineering students participating in graduate research groups. Missing data were imputed, and responses were weighted by gender, discipline, degree program and nationality. Exploratory factor analysis identified four factors describing research group experiences. Regression models were built for two outcomes: satisfaction with research group experience and intention to complete degree. Control variables included gender, discipline, degree program, nationality, year in program and institution.
Findings
Fifty-five per cent of the variance in satisfaction was described by a model including agency, support, international diversity and group climate. Sixty-five per cent of variance in intent to complete was described by a model comprising international diversity, agency and support. Several control variables were significant.
Originality/value
Agency and support in particular were the most influential predictors of both satisfaction and intention, suggesting that future efforts should emphasize stable funding, clear expectations, access to mentors and agency-building experiences to help students take an active role in their own success.

This paper aims to draw up the state of scientific knowledge in the field of Formula 1 with relation to tourism and urban studies.
Abstract
Purpose
This paper aims to draw up the state of scientific knowledge in the field of Formula 1 with relation to tourism and urban studies.
Design/methodology/approach
This study is based on a systematic review of the scientific literature regarding this issue. Using targeted keywords and the analysis of various documentary databases, 8,075 references were identified and 40 documents were analyzed in an exhaustive manner.
Findings
This study presents a very nuanced portrait of the urban and tourism impacts of Formula 1 on the host territories. In many of the studies analyzed, a gap may be noted, sometimes flagrant, between the development goals of the promoters of these mega-events and local realities. This study also highlights the fact that Formula 1 has established itself as a sports events industry that can renew and enhance the brand image of certain cities.
Originality/value
Very few recent studies have exhaustively reviewed the scientific literature published in English and French with regard to the field of Formula 1 from a tourism and urban perspective. This study makes it possible to identify the main analytical findings and research perspectives resulting from this scientific work while discussing them using a theoretical framework related to the hypermodern character of different societies.

Abstract
Purpose
The disposition effect remains one of the most significant investor behavior puzzles. This study aims to consolidate the knowledge, explore current dynamics, elicit trends and offer future research directions to demystify the disposition effect.
Design/methodology/approach
This study applies the hybrid review method. It first used bibliometric analysis (212 documents), followed by content analysis (54 articles) to analyze the breadth and depth of literature on the disposition effect.
Findings
This study presents performance analysis and science mapping. It identifies five main research streams: evidence, implications and mitigation techniques; theoretical explanations; investor biases and hedonic framing; attributes, beliefs and preferences; and implications for asset pricing and market efficiency. This study further offers future research directions for disposition effect research.
Research limitations/implications
This study deploys sequential bibliometric and content analysis. A meta-analysis of quantitative articles could provide specific insights regarding the disposition effect. Besides, this study is based on Scopus-indexed journals only.
Practical implications
This study benefits investors and portfolio managers as they learn effective ways to guard against the disposition effect. Policymakers may tweak tax laws to incentivize long-term holding, and regulators can run investor education campaigns to minimize the disposition effect’s consequences effectively.
Originality/value
To the best of the authors’ knowledge, this is probably the first hybrid review of high-quality, contemporary articles on the disposition effect that offers science mapping, research streams, future research directions and a succinct summary of theories, contexts, characteristics and methods deployed in the field of research.

Abstract
The moral hazard problem which obstructs external equity financing of farm businesses is studied using the principal‐agent framework. We assume that the supplier of external equity capital (the principal) cannot directly observe the farmer’s (agent’s) effort, but can observe the random outcome of the effort. We solve for the optimal farm income‐sharing rule that includes an extra share to the agent. The extra share is dependent on the random outcome and is provided to induce optimal effort from the agent. Results show a farmer’s effort is inversely related to the level of risk aversion and the riskiness of the project. Thus, an investor must share more income when a farmer is more risk averse or a project is more risky.

Abstract
This chapter discusses how attachment theory, a theory that provides insight into the processes through which psychological and emotional bonds are developed in relationships, can be useful for understanding mentoring relationships. We develop a conceptual model emphasizing how attachment-related constructs and their relationships with mentors’ and protégés’ behaviors and emotions influence each phase of a mentoring relationship. Recognizing reciprocity in the mentoring process, the model also explains how the interpersonal dynamics of the mentor–protégé relationship influence the benefits gained by both partners. Propositions for future research on mentoring relationships are provided. We contend that examining mentoring through the lens of attachment theory can increase our understanding of the underlying factors or mechanisms that determine individuals’ involvement in mentoring relationships and differentiate successful from unsuccessful mentoring relationships. The research and practical implications are discussed.
