Abstract

Reports that measurable amounts of polymer degradation occur during the fabrication of objects from polymer coated ceramic powders by selective laser sintering (SLS). Argues that because the binder is important in achieving strong green parts that can be handled with minimal breakage during post‐processing operations, it is essential to minimize the extent of binder losses. As the first step towards understanding the mechanisms of binder degradation, this paper presents a thermal model of the physical system, noting that the agreement between theory and experiment are good. The model is used to help determine the most influential parameters affecting binder losses during fabrication from polymer coated powders. Predicts that adjustments to laser beam diameter, laser scanning distance and gaseous environment will strongly affect polymer binder degradation during processing. Further predicts correctly that polymer degradation during SLS processing is not sensitive to the inherent degradation kinetics of the polymer.

Abstract

In this chapter, we summarize and build on the current state of the customer mistreatment literature in an effort to further future research on this topic. First, we detail the four primary conceptualizations of customer mistreatment. Second, we present a multilevel model of customer mistreatment, which distinguishes between the unfolding processes at the individual employee level and the service encounter level. In particular, we consider the antecedents and outcomes unique to each level of analysis as well as mediators and moderators. Finally, we discuss important methodological concerns and recommendations for future research.

Abstract

There is a huge amount of information and data stored in publicly available online databases that consist of large text files accessed by Boolean search techniques. It is widely held that less use is made of these databases than could or should be the case, and that one reason for this is that potential users find it difficult to identify which databases to search, to use the various command languages of the hosts and to construct the Boolean search statements required. This reasoning has stimulated a considerable amount of exploration and development work on the construction of search interfaces, to aid the inexperienced user to gain effective access to these databases. The aim of our paper is to review aspects of the design of such interfaces: to indicate the requirements that must be met if maximum aid is to be offered to the inexperienced searcher; to spell out the knowledge that must be incorporated in an interface if such aid is to be given; to describe some of the solutions that have been implemented in experimental and operational interfaces; and to discuss some of the problems encountered. The paper closes with an extensive bibliography of references relevant to online search aids, going well beyond the items explicitly mentioned in the text. An index to software appears after the bibliography at the end of the paper.

Abstract

This chapter takes a panoramic view to explore the lives of collegiate Black men. We begin with brief reflections from our own experiences to position ourselves to and alongside Black men's lives and college years. After setting the stage through our own reflections, we explore the literature on Black men's lives during their college years and pay particular attention to their social statuses, campus engagement, and health and well-being. Two critical components in many Black men's collegiate experiences are how they are projected in wider US society through deficit-based perspectives and repositioned away from educational success. We interrogate these realities and advance a discussion on ways to improve the conditions, environment, and understanding of their college journeys and possibilities. We conclude with recommendations for research, practice, and policy.

Abstract

Purpose

The purpose of this paper is to provide a literature review of investigations into the specific disability of deafness in the field of sociology and other closely related fields.

Methodology/approach

After a pilot search using databases appropriate to social science research, we developed key search terms and, using an inductive approach, we identified major themes in the literature.

Findings

Our review shows that deafness has been investigated for a long time in sociology and other related fields, that there is a wide range of themes in scholarly work on the experiences of deaf communities and deaf people, and that conceptualizations of deafness and d/Deaf communities have changed over time. We organize this paper around six major themes we identified, and a few highlighted pieces of scholarship illustrate these themes along the way. We particularly focus on scholarship from the late 1960s through the early 1990s as emblematic of seismic shifts in studying deafness, although we do highlight little known nineteenth century work as well.

Research implications

This paper captures the legacy of this past scholarship and reveals that deafness is a rich site of inquiry that can contribute to the field of sociology. It is also a valuable resource for any future sociological research into deafness, deaf people, and deaf communities. We conclude with a discussion of our findings, commentary on the extent to which previous scholarship on the sociology of deafness has or has not figured into current scholarship and suggestions for future research.

Abstract

Although the family plays a key role in affecting offender behavior, little research examines how sanctioning contexts affect familial relationships. Using data from the Australian reintegrative shaming experiments (RISE), we investigate how the processing of offenders via court and conference affects their bonds with family members by examining the type of shaming – reintegrative or disintegrative – they experience. In contrast to disintegrative or stigmatizing shaming, which tends to be associated with court processing, reintegrative shaming shames the act and not the moral character of the offender, allowing for the reparation of social ties. We find that despite higher levels of stigmatization in conferences, this form of processing is also more reintegrative and strengthens family relationships to a greater extent than courts, with offenders feeling prouder of being a member of their family and indicating that familial closeness and respect increased. Moreover, reintegrative but not disintegrative shaming mediates the relationship between criminal justice processing and family relationships.
