This paper aims to investigate methods of implementing in‐process fault avoidance in robotic friction stir welding (FSW).

Investigations into the possibilities for automatically detecting gap‐faults in a friction stir lap weld were conducted. Force signals were collected from a number of lap welds containing differing degrees of gap faults. Statistical analysis was carried out to determine whether these signals could be used to develop an automatic fault detector/classifier.

The results demonstrate that the frequency spectra of collected force signals can be mapped to a lower dimension through discovered discriminant functions where the faulty welds and control welds are linearly separable. This implies that a robust and precise classifier is very plausible, given force signals.

Future research should focus on a complete controller using the information reported in this paper. This should allow for a robotic friction stir welder to detect and avoid faults in real time. This would improve manufacturing safety and yield.

This paper is applicable to the rapidly expanding robotic FSW industry. A great advantage of heavy machine tool versus robotic FSW is that the robot cannot supply the same amount of rigidity. Future work must strive to overcome this lack of mechanical rigidity with intelligent control, as has been examined in this paper.

This paper investigates fault detection in robotic FSW. Fault detection and avoidance are essential for the increased robustness of robotic FSW. The paper's results describe very promising directions for such implementation.

“All things are in a constant state of change”, said Heraclitus of Ephesus. The waters if a river are for ever changing yet the river endures. Every particle of matter is in continual movement. All death is birth in a new form, all birth the death of the previous form. The seasons come and go. The myth of our own John Barleycorn, buried in the ground, yet resurrected in the Spring, has close parallels with the fertility rites of Greece and the Near East such as those of Hyacinthas, Hylas, Adonis and Dionysus, of Osiris the Egyptian deity, and Mondamin the Red Indian maize‐god. Indeed, the ritual and myth of Attis, born of a virgin, killed and resurrected on the third day, undoubtedly had a strong influence on Christianity.

Whether they are in a leadership program, participate in an organization, or engage in school-based extra-curricular activities, there does not appear to be a shortage of leadership development opportunities for youth. Despite the prominence of these experiences, the lack of youth leadership development models available for educators can pose a challenge in creating opportunities intentionally designed to enhance leadership learning and development. This study uncovers prevalent leadership competencies embedded in four professional preparation frameworks, three research studies, and objectives of four large national youth leadership organizations to create a holistic youth leadership competency development model.

This paper aims to explore how historical context influences the content and selection of rhetorical legitimation strategies. Using case study method, this paper will focus on how insurance companies and labor tried to defend their legitimacy in the context of enactment of Medicare in the USA. What factors influenced the strategic (rhetorical) decisions made by insurance companies and labor unions in their institutional work?

The study is empirically grounded in archival research, involving an analysis of over 9,000 pages of congressional hearings on Medicare covering the period 1958–1965.

The authors show that rhetorical legitimation strategies depend significantly on the specific historical circumstances in which those strategies are used. The historical context lent credibility to certain arguments and organizations are forced to decide either to challenge widely held assumptions or take advantage of them. The authors show that organizations face strong incentives to pursue the latter option. Here, both the insurance companies and labor unions tried to show that their positions were consistent with classical liberal ideology, because of high respect of classical liberal principles among different stakeholders (policymakers, voters, etc.).

It is uncertain how much the results of the study could be generalized. More information about the organizations whose use of rhetorics the authors studied could have strengthened our conclusions.

The practical relevancy of the revised paper is that the authors should not expect hegemony challenging rhetorics from organizations, which try to influence legislators (and perhaps the larger public). Perhaps (based on the findings), this kind of rhetorics is not even very effective.

The paper helps to understand better how organizations try to advance their interests and gain acceptance among the stakeholders.

In this paper, the authors show how historical context in practice influence rhetorical arguments organizations select in public debates when their goal is to influence the decision-making of their audience. In particular, the authors show how dominant ideology (or ideologies) limit the options organizations face when they are choosing their strategies and arguments. In terms of the selection of rhetorical justification strategies, the most pressing question is not the “real” broad based support of certain ideologies. Insurance company and labor union representatives clearly believed that they must emphasize liberal values (or liberal ideology) if they wanted to gain legitimacy for their positions. In existing literature, it is often assumed that historical context influence the selection of rhetorical strategies but how this in fact happens is not usually specified. The paper shows how interpretations of historical contexts (including the ideological context) in practice influence the rhetorical strategies organizations choose.

This paper aims to extend the literature on wicked problems in consumer research by exploring athlete and consumer vulnerability in sport and the potential role that social marketing can play in addressing this problem.

This paper conceptualises the wicked problem of athlete and consumer vulnerability in sport, proposing a multi-theoretical approach to social marketing, incorporating insights from stakeholder theory, systems theory and cocreation to tackle this complex problem.

Sport provides a rich context for exploring a social marketing approach to a wicked problem, as it operates in a complex ecosystem with multiple stakeholders with differing, and sometimes conflicting, objectives. It is proposed that consumers, particularly those that are highly identified fans, are key stakeholders that have both facilitated the problematic nature of the sport system and been rendered vulnerable as a result. Further, a form of consumer vulnerability also extends to athletes as the evolution of the sport system has led them to engage in harmful consumption behaviours. Social marketing, with its strategic and multi-faceted focus on facilitating social good, is an apt approach to tackle behavioural change at multiple levels within the sport system.

Sport managers, public health practitioners and policymakers are given insight into the key drivers of a growing wicked problem as well as the potential for social marketing to mitigate harm.

This paper is the first to identify and explicate a wicked problem in sport. More generally it extends insight into wicked problems in consumer research by examining a case whereby the consumer is both complicit in, and made vulnerable by, the creation of a wicked problem. This paper is the first to explore the use of social marketing in managing wicked problems in sport.

The coach−athlete relationship mediates the relationship between sports participation and student-athlete character, health and well-being outcomes. High school athletic administrators (AAs) can provide critical leadership, mentorship and direction for coaches to optimize student-athlete performance and human development. Social and emotional learning (SEL) is an evidence-based approach to developing adult and student competencies for holistic development across the lifespan that has been primarily performed and researched in the classroom. The purpose of this research is to capture the lived experiences of AAs applying a novel SEL-based curriculum (InSideOut Initiative, ISOI) with coaches and student-athletes in high school sports.

Interviews of 10 AAs captured their lived experiences of applying SEL-based leadership and coaching and their perception of its impact on coaches and student-athletes in high school athletics.

AAs described leadership and coaching that are characterized by (1) safety, support and mentorship; (2) skill and support-based behavior modeling; (3) trusting, loving and supportive relationships; (4) self-reflection of values/beliefs and behaviors that impact self, student-athlete and culture; (5) the influence of emotions on the aforementioned; (6) the ability to have a long-term, sustainable impact on student-athletes and (7) alignment with their immediate environmental context.

The data captured in this study suggest that ISOI-trained AAs practice SEL-competent leadership and coaching. Evaluation of the novel application of SEL-based interventions in athletics will be useful to understanding their effects on participant social and emotional competencies and outcomes traditionally associated with classroom-based SEL applications.

Athletic administrator interviews describe an approach to high school sports that requires a reconceptualization of the purpose of athletics. When the high school sport operates as a curriculum, integrated opportunity for its student-athletes and athletic administrator and coach leadership aligns with this overarching philosophy, there may be increased potential for positive youth development.

The results of this research are valuable in demonstrating preliminary evidence of how SEL-based leadership and coaching is applied and impacts adult and student-athletes in a unique sport context.

This study aims to identify key supply chain challenges and opportunities of the case of Hong Kong toy manufacturing company during the COVID-19 outbreak and develop a comprehensive structural relationship to rank them.

In this study, a toy model company in Hong Kong is considered to discuss about what challenges and opportunities have the biggest impacts on non-necessary goods companies and how to deal with different impacts on entire supply chain flow disruption during COVID-19. A semi-structured interview with five decision-makers from the company was made to give key challenges and opportunities scores. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) technique is used to establish the model and rank them afterward to overcome the challenges.

From the data analysis and results, “salary of employee” and “inconvenient transportation” have emerged as top and bottom key challenges respectively. The sequence of organized challenges in the list needs to mitigate one by one in this order to improve the supply chain performance. The “client's orders’ frequency, customer management” and “supplier/partner relationship management” are identified as the top and bottom respectively to develop the opportunities.

These key challenges and opportunities are identified as contributing attributes and provide the way to measure to improve production, profits and sustainable growth of the toy manufacturing company during a pandemic. Moreover, it helps to improve the distribution level and good planning with appropriate decision making to manage the supply chain performance considering humanitarian aspects during a pandemic outbreak.

The novelty of this study is to identify the key supply chain challenges and opportunities measured by the TOPSIS method to rank them and consider the case of a Hong Kong toy manufacturing company as a case-based approach to measuring its performance during the COVID-19 outbreak.

This paper aims to outline the prosocial leadership development process for guiding pedagogical and social justice course goals as a means to foster prosocial leadership values within the millennial generation.

The paper is guided by a social justice framework and proven classroom pedagogies as a means to align millennial characteristics within the four stages of the prosocial leadership development process.

An educational rubric is provided as a means to guide classroom pedagogies, course goals and millennial characteristics through a prosocial leadership development process.

The paper is conceptual in nature, and therefore, theoretical correspondence remains speculative.

The research in this paper provided guidelines for educators to use pedagogical practices as a means to develop prosocial values as a basis for organizational leadership behaviors.

This leadership development process when facilitated through proven pedagogical techniques (guided by established social justice curriculum goals) and is within the context of millennial characteristics (those born between the years 1982 and 2005) becomes catalytic in empowering leaders to be a remedy for the world’s environmental and social challenges.

This paper connects characteristics of millennials to a prosocial leadership development model.
