Abstract

Purpose

The paper reports an investigation into the mechanical behaviour of hybrid components produced by combining the capabilities of metal injection moulding (MIM) with the laser-based powder bed fusion (PBF) process to produce small series of hybrid components. The research investigates systematically the mechanical properties and the performance of the MIM/PBF interfaces in such hybrid components.

Design/methodology/approach

The MIM process is employed to fabricate relatively lower cost preforms in higher quantities, whereas the PBF technology is deployed to build on them sections that can be personalised, customised or functionalised to meet specific technical requirements.

Findings

The results are discussed, and conclusions are made about the mechanical performance of such hybrid components produced in batches and also about the production efficiency of the investigated hybrid manufacturing (HM) route. The obtained results show that the proposed HM route can produce hybrid MIM/PBF components with consistent mechanical properties and interface performance which comply with the American Society for Testing and Materials (ASTM) standards.

Originality/value

The manufacturing of hybrid components, especially by combining the capabilities of additive manufacturing processes with cost-effective complementary technologies, is designed to be exploited by industry because they can offer flexibility and cost advantages in producing small series of customisable products. The findings of this research will contribute to further develop the state of the art in regards to the manufacturing and optimisation of hybrid components.

Abstract

The purpose of this paper is to suggest that the case of General Guillaume-Henri Dufour may offer useful ideas for the development of responsible leadership in military ethics. Military ethics is a field of growing importance. And in the military profession, leadership is particularly valued. The systematic and continuing production of leaders at all levels is a constant task of military forces in any country, and the need for leaders who are responsible and ethical is not only desirable, but also essential – as a variety of ethical failures have shown us.

Guillaume-Henri Dufour was a decorated soldier serving Switzerland as a general, who founded a military academy and trained others in the military sciences, who served as a politician, and who contributed noted achievements in the fields of cartography and civil engineering. A short sketch of his life is provided, and then focus turns to two specific occasions: the Sonderbund War and the agreement for the Geneva Convention for the Amelioration of the Condition of the Wounded in Armies in the Field.

Abstract

Purpose

The outbreak of the pandemic makes it more difficult to manage the safety or health of construction workers in infrastructure construction. Risk events in construction workers' material handling tasks are highly relevant to workers' work-related musculoskeletal disorders. However, there are still many problems to be resolved in recognizing risk events accurately. The purpose of this research is to propose an automatic and non-invasive recognition method for construction workers in material handling tasks during the pandemic based on smartphone and machine learning.

Design/methodology/approach

This research proposes a method to recognize and classify four different risk events by collecting specific acceleration and angular velocity patterns through built-in sensors of smartphones. The events were simulated with anterior handling and shoulder handling methods in the laboratory. After data segmentation and feature extraction, five different machine learning methods are used to recognize risk events and the classification performances are compared.

Findings

The classification result of the shoulder handling method was slightly better than the anterior handling method. By comparing the accuracy of five different classifiers, cross-validation results showed that the classification accuracy of the random forest algorithm was the highest (76.71% in anterior handling method and 80.13% in shoulder handling method) when the window size was 0.64 s.

Originality/value

Less attention has been paid to the risk events in workers' material handling tasks in previous studies, and most events are recorded by manual observation methods. This study provided a simple and objective way to judge the risk events in manual material handling tasks of construction workers based on smartphones, which can be used as a non-invasive way for managers to improve health and labor productivity during the pandemic.

Abstract

President Bill Clinton has had many opponents and enemies, most of whom come from the political right wing. Clinton supporters contend that these opponents, throughout the Clinton presidency, systematically have sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office, including Travelgate, the death of Deputy White House Counsel Vincent Foster, the Filegate controversy, and the Monica Lewinsky matter. This bibliography identifies these and other means by presenting citations about these individuals and organizations that have opposed Clinton. The bibliography is divided into five sections: General; “The conspiracy stream of conspiracy commerce”, a White House‐produced “report” presenting its view of a right‐wing conspiracy against the Clinton presidency; Funding; Conservative organizations; and Publishing/media. Many of the annotations note the links among these key players.

Abstract

Purpose

This paper aims to evaluate the career patterns and global mobility trajectories of hospitality and tourism graduates that are relevant for global knowledge and local talent management.

Design/methodology/approach

This study maps and assesses the public profiles of over 2,000 hospitality and tourism graduates from five institutions each from a different territory using a popular online professional network.

Findings

The findings highlight a network of worldwide mobility from hospitality and tourism graduates of the five institutions. The findings also suggest five different types of mobility trajectories (i.e. stateside, intra-regional, continental, inter-regional and global) and career patterns (i.e. rooted, prospector, seeker, two-homes and wanderer).

Research limitations/implications

Geographical mobility of graduates in tourism and hospitality is one of the less studied phenomena; however, it is important to understand due to growing concerns regarding globalization of the workplace and internationalization of education.

Practical implications

This study provides insights into how knowledge transfer and talent management could be impacted by the global graduate movements.

Originality/value

This is one of the first studies to date to combine mobility trajectories with a classification of career patterns to provide implications relevant for global knowledge and local talent management.

Abstract

Purpose

Using the substitute for leadership framework, the purpose of this paper is to verify whether employees’ perceived value congruence with their organization can act as a moderator of the relationship between transformational leadership and empowered behaviors. A triple moderation hypothesis, wherein value congruence could both enhance or substitute leadership practices depending on employee tenure, is tested.

Design/methodology/approach

Self-reported data were collected from 1,934 employees of a large public organization.

Findings

Hierarchical regressions show that value congruence enhances transformational leadership’s effectiveness in new employees, but plays either a substitute role or no role at all in more tenured employees.

Research limitations/implications

Findings suggest that the substitutes for leadership framework are useful in understanding both the enhancing and substitute role of value congruence with regards to transformational leadership. This study also underlines this framework’s complexity and the need for additional research that goes beyond bivariate models to further our understanding of transformational leadership moderators.

Practical implications

The knowledge of when leadership practices are enhanced or substituted could help leaders focus their efforts to maximize empowered behaviors.

Originality/value

This study verifies the theorized moderating role of value congruence in transformational leadership, which has been largely ignored in research. Additionally this study shows that this role can fluctuate according to tenure.

Abstract

Purpose

This paper aims to propose a method to evaluate the information obtained on harmonics calculations and to estimate the precision of results using finite element method for an innovative motor topology in which some well-known meshing rules are difficult to apply.

Design/methodology/approach

The same magnetostatic problem is solved with several mesh sizes using both scalar and vector potentials magnetics formulations on a complex topology, an axial claw pole motor (ACPM). The proposed method lies in a comparison between the two weak formulations to determine what information is obtained on harmonics calculations and to estimate its precision. Moreover, an original mesh method is applied in the air gap to improve the numerical results.

Findings

The precision on harmonics calculations using finite element method on an ACPM is estimated. For the proposed motor and mesh, only the mean value (even with large mesh) and the first harmonic (with fine mesh) of torque are calculated with a good accuracy. This results confirm that the non-respect of the meshing rules have a strong impact on the results and that scalar and vector potentials magnetics formulations do not give exactly the same results. Before using torque harmonics values in vibration calculations, a finite element model has to be validated by using both fomulations.

Research limitations/implications

This method is time-consuming and only applied on an ACPM in this work.

Originality/value

The axial claw pole motor, for which the classic meshing rules cannot be applied, is a complex topology very under-studied. To improve the calculation of space harmonics, the authors proposed to split the airgap into four parts. Then in the two central parts, the meshing step of the structured mesh is equal to the rotating step.

Abstract

Both the Austrian and Bloomington Schools emphasize the dispersal of information to the level of individual agents. An underappreciated difference is the Bloomington emphasis on the moral psychology of agents and its relation to covenant. Covenant refers to a habit, a sense of obligation to consider the interests of the other in decision making, and a commitment to do so that is not easily or unilaterally broken. This chapter seeks to elaborate the lineage of covenant in constituting political order and its implications for the moral psychology of agents and artisanship. This exploration raises issues of metaphysical foundations as they relate to values and to the Hobbesian–Aristotelian divide in starting points. An application to the environmental crisis, with particular reference to vested interests promoting disinformation, obfuscation, and doubt about anthropogenic climate change, suggests value in emphasizing covenant.

Abstract

Purpose – This chapter responds to interdisciplinary debates regarding studies of sex, sexuality, and gender. I briefly examine how the sex/gender paradigm of the 1960s shaped feminist theory in the social sciences and explore two feminist frameworks that have contested the sex/gender paradigm: West and Zimmerman's “doing gender” and Butler's performativity. I situate this literature, and related debates about intersectionality, in the context of Margaret Andersen's (2005) Sociologists for Women in Society (SWS) feminist lecture.

Methodology/approach – Using empirical analyses of brief television excerpts, I develop an ethnomethodological study of practice and poststructural analysis of discourse to demonstrate how trenchant forms of cultural knowledge link together gender, sex, and sexuality.

Findings – Sex and gender function as disciplinary forces in the service of heterosexuality; consequently studies of gender that do not account for sexuality reproduce heterosexism and marginalize queer sexualities. These findings, considered in relationship to Andersen's analysis of intersectionality, illustrate both a narrow conceptualization of the field rooted to a 19th century European model and a methodological mandate that must be examined in relationship to the politics of social research.

Practical implications – A more fruitful conceptual starting point in thinking through intersectionality may be citizenship, rather than systematic exploitation of wage labor. In addition, a more full analysis of intersectionality would also require that we rethink our methodological orientations.

Originality/value of paper – The chapter illustrates some of the analytic effects and political consequences that commonsense knowledge about gender, sex, and sexuality holds for feminist scholarship and advances alternative possibilities for future feminist research.

Abstract

Purpose

The purpose of this chapter is twofold: to explore the difficulties and potential of turning to the perpetrator of sexual violence; and to track the affective economy of engaging with perpetrator accounts.

Design/methodology/approach

This chapter will consider one of the earliest feminist studies of incest, Sandra Butler’s (1978) Conspiracy of Silence: The Trauma of Incest, followed by an analysis of Philippe Bourgois’ (1995, 1996, 2004) ethnographic study of Puerto Rican crack dealers. These are important studies for the fact that both Butler and Bourgois let the men speak freely of their violence, which for the Puerto Rican cracker dealers include tales of gang rape.

Findings

The chapter endorses the need to study the perpetrator, arguing that it is imperative to ensure the demythologization of perpetrators. It finds also that feminists must explore how they will teach emotionally difficult material, and how they negotiate the legacy of radical feminism. The chapter concludes that there are times when politics requires little theoretical innovation, requiring instead a willingness to repeat known insights and to fight back with words.

Social implications

This chapter has implications for classroom practice.

Originality/value

The value of this chapter is its demand to reconsider the doing of feminism in the classroom when the split between feminist theory and activism appears greater than ever.
