In this paper, the authors document the existence of price clustering in the US corporate bond market.

Using a sample of 8,422,593 corporate bond trades in 2014, the authors find that over 18% (1,522,284 trades) of all bond trades end in a clustered price, defined as a price ending in 00, 25, 50, or 75.

Overall, the authors find that both bond rating category and risk, as measured by standard deviation of prices, play a role in price clustering; speculative grade bonds account for the majority of clustered prices. Clustered prices are more likely to have higher coupon rates, higher prices, and higher standard deviations of price than bonds with non-clustered prices. Regardless of size, both buy and sell dealer trades with customers (relative to interdealer trading) lead to an increase in price clustering. Dealers appear to use clustered prices when purchasing from and selling to institutions and, therefore, may use a clustered price to insulate themselves from the risk of asymmetric information. Additionally, the prevalence of clustered prices for retail-sized dealer sell trades suggests that dealers exercise dealer power over retail-sized traders.

This paper contributes to the literature on price clustering by examining trade price clustering of corporate bonds. It is different from previous papers on price clustering in equities. Given that bonds tend to be priced off of yield, it is unusual that trade prices cluster. It also demonstrates what kind of bonds cluster and with which customers dealers trade at clustered prices. It parallels other research in demonstrating dealer power over retail-sized traders.

The first article on the subject, which appeared in the August issue of Industrial and Commercial Training, described the development of a training course in BEA for Passenger Services Staff. The aim of this training is to improve personal service. Its most important element is role‐playing of typical interactions between staff and passengers; these are recorded on video‐tape and replayed for viewing and discussion. A good deal of reading, thinking and research was done before and during the training development. Visits were made to the training centres of several airlines, in Britain and the USA; research workers in both countries were also consulted. Five relevant views of the subject will be examined. These are: • the concept of social skill — Michael Argyle • the analysis of verbal behaviours — Neil Rackham • T‐group training — particularly the research by Cary Cooper and Henry Odie for the Hotel and Catering ITB • transactional analysis — work in Pan American Airways and American Airlines • applied learning in management training — by Mel Sorcher and Arnold Goldstein of Syracuse, USA A reading list giving references to these ideas and authors is given at the end of the article. The intention here is briefly to describe these views, evaluate their relevance to Customer Service Training generally, and show how they have influenced the philosophy and the design of the BEA training. Naturally, more weight will be given to one view than to another in the analysis that follows, but it should be emphasised that there is no intention to choose nor to reject any particular theory or training development. The different approaches are often complementary, each provides insight into the problems of human interaction.

What is it about academia anyway? We profess to hate it, spend endless amounts of time complaining about it, and yet we in academia will do practically anything to stay. The pay may be low, job security elusive, and in the end, it's not the glamorous work we envisioned it would be. Yet, it still holds fascination and interest for us. This is an article about American academic fiction. By academic fiction, I mean novels whosemain characters are professors, college students, and those individuals associated with academia. These works reveal many truths about the higher education experience not readily available elsewhere. We learn about ourselves and the university community in which we work.

The purpose of this paper is to present exciting and innovative research questions in service operations that are aligned with eight key themes and related topics determined by the Journal of Service Management (JOSM) Service Operations Expert Research Panel. By offering a good number of such research questions, this paper provides a broad range of ideas to spur conceptual and empirical research related to service operations and encourage the continued creation of deep knowledge within the field, as well as collaborative research across disciplines that develops and incorporates insights from service operations.

Based on a Delphi study, described in the companion article, “Service Operations: What Have We Learned?,” the panel identified eight key research themes in service operations where leading-edge research is being done or has yet to be done (Victorino et al., 2018). In this paper, three or four topics within each theme are selected and multiple questions for each topic are proposed to guide research efforts. The topics and questions, while wide-ranging, are only representative of the many ongoing research opportunities related to service operations.

The field of service operations has many interesting research topics and questions that are largely unexplored. Furthermore, these research areas are not only increasingly integrative across multiple themes within operations but often transcend functional disciplines. This creates opportunities for ever more impactful research with a greater reach throughout the service system and suggests that service researchers, regardless of functional affiliation, can contribute to the ongoing conversation on the role of service operations in value creation.

Leveraging the collective knowledge of the JOSM Service Operations Expert Research Panel to expand on the research themes generated from the Delphi study, novel questions for future study are put forward. Recognizing that the number of potential research questions is virtually unlimited, summary questions by theme and topic are also provided. These questions represent a synopsis of the individual questions and can serve as a quick reference guide for researchers interested in pursuing new directions in conceptual and empirical research in service operations. This summary also serves as a framework to facilitate the formulation of additional research topics and questions.

The purpose of this paper is to identify research themes in service operations that have great potential for exciting and innovative conceptual and empirical work. To frame these research themes, the paper provides a systematic literature review of operations articles published in the Journal of Service Management (JOSM). The thorough review of published work in JOSM and proposed research themes are presented in hopes that they will inspire impactful research on service operations. These themes are further developed in a companion paper, “Service operations: what’s next?” (Field et al., 2018).

The JOSM Service Operations Expert Research Panel conducted a Delphi study to generate research themes where leading-edge research on service operations is being done or has yet to be done. Nearly 700 articles published in JOSM from its inception through 2016 were reviewed and classified by discipline focus. The subset of service operations articles was then further categorized according to the eight identified research themes plus an additional category that primarily represented traditional manufacturing approaches applied in service settings.

From the Delphi study, the following key themes emerged: service supply networks, evaluating and measuring service operations performance, understanding customer and employee behavior in service operations, managing servitization, managing knowledge-based service contexts, managing participation roles and responsibilities in service operations, addressing society’s challenges through service operations, and the operational implications of the sharing economy. Based on the literature review, approximately 20 percent of the published work in JOSM is operations focused, with earlier articles predominantly applying traditional manufacturing approaches in service settings. However, the percentage of these traditional types of articles has been steadily decreasing, suggesting a trend toward dedicated research frameworks and themes that are unique to the design and management of services operations.

The paper presents key research themes for advancing conceptual and empirical research on service operations. Additionally, a review of the past and current landscape of operations articles published in JOSM offers an understanding of the scholarly conversation so far and sets a foundation from which to build future research.

This paper aims to demonstrate the benefits of using different impeder materials for induction tube welding systems.

To show the difference in using various impeder materials, a new approach was taken to model tube welding systems in two and three dimensions. Three-dimensional (3-D) electromagnetic models were used to determine the current distribution along the weld vee as well as the permeability of the tube along the length of the welding system. Two-dimensional (2-D) coupled electromagnetic plus thermal models with rotational movement were used to determine the temperature distribution in the heat-affected zone.

Simulation results suggest upwards of 25 per cent system power savings when using a soft magnetic composite (SMC) impeder rather than the traditional ferrites.

There is currently a lack of experimental data to validate the models, but future work will include comparison of models to real-world trials.

When dealing with tube welding systems, there are possibilities to improve process efficiency or increase production quality and output by improving the impeder material.

While simulations of tube welding systems have been done previously, studies on improving impeder materials are rarely carried out. This paper brings to light possible improvements to be made to induction tube welding systems.

Taking the perspective that leadership education is similar to art education created a bridge connecting the leadership education literature with the large and rich body of literature on art education and art history. A survey of the more prominent Renaissance art academies was employed to illuminate the education practices of that extraordinary time, and then consider whether these practices had application to modern day leadership education. Results directly challenged the efficacy of the skills approach to leadership education, affirmed the importance of the mentoring method, supported the communities of practice method as a powerful tool for leadership education, argued for the idea of a talent for leadership, proposed designing leadership games and simulations that included positive and negative consequences, and stressed the importance of creating college and university based leadership academies.

Child psychiatrist Leo Kanner (pronounced “Konner;” Feinstein, 2010, p. 19) published a ground-breaking paper in 1943 that introduced the world to the present-day concept of autism (Fombonne, 2003; Goldstein & Ozonoff, 2009; Roth, 2010). Prior to Kanner, however, several physicians described the condition of autism without identifying it as such. A textbook published in 1809, titled Observations on Madness and Melancholy, contained a description of a boy whose symptoms fit the modern definition of autism (Feinstein, 2010; Vaillant, 1962). The book's author, Dr. John Haslam, wrote about a 5-year-old male who was admitted to the Bethlem Asylum in 1799 with a medical history that included a case of measles when he was 1 year old. The boy's mother claimed that at age 2 years, her son became harder to control. She also indicated that he did not begin to walk until he was 2½ years of age and did not talk until he was 4 years old. Once hospitalized, the boy cried only briefly upon separation from his mother and was “constantly in action” (Vaillant, 1962, p. 376), suggesting that he was hyperactive. Hyperactivity is a characteristic commonly found in children with ASDs (APA, 2000; Wicks-Nelson & Israel, 2009). Although this child watched other boys at play in the hospital, he never joined them and played intently with toy soldiers by himself. The boy could not learn to read and always referred to himself in the third person (Vaillant, 1962). Grammatical errors in speech can be observed among individuals with ASDs (Roth, 2010; Wicks-Nelson & Israel, 2009).
