The consolidation process and morphology evolution in ceramics-based additive manufacturing (AM) are still not well-understood. As a way to better understand the ceramic selective laser sintering (SLS), a dynamic three-dimensional computational model was developed to forecast thermal behavior of hydroxyapatite (HA) bioceramic.

AM has revolutionized automotive, biomedical and aerospace industries, among many others. AM provides design and geometric freedom, rapid product customization and manufacturing flexibility through its layer-by-layer technique. However, a very limited number of materials are printable because of rapid melting and solidification hysteresis. Melting-solidification dynamics in powder bed fusion are usually correlated with welding, often ignoring the intrinsic properties of the laser irradiation; unsurprisingly, the printable materials are mostly the well-known weldable materials.

The consolidation mechanism of HA was identified during its processing in a ceramic SLS device, then the effect of the laser energy density was studied to see how it affects the processing window. Premature sintering and sintering regimes were revealed and elaborated in detail. The full consolidation beyond sintering was also revealed along with its interaction to baseplate.

These findings provide important insight into the consolidation mechanism of HA ceramics, which will be the cornerstone for extending the range of materials in laser powder bed fusion of ceramics.

Limited research investigates the travel behavior of the retired adult population before retirement and how it changes after retirement. Currently, most of the travel research on the retired population explores their current travel patterns in retirement. Increased research on travel activity before retirement would allow managers in the tourism industry to better adapt and anticipate the changing needs and demographics of seniors, notably, the various ways this growing population manages travel and specific barriers or concerns they face. The authors examined the changes to the travel patterns – defined as travel frequency, mode of transportation, and geographic location/s (domestic or international) – of those retired traveling before and after retirement. Since retirement is a time of major life change, the authors analyzed how this event impacts travel behavior. This research identified barriers these Baby Boomers and those who are retired experience while traveling, including health, social activities, and financial status, which may impact their travel, the degree to which their travel behavior is affected, and specific environmental and personal factors impacting their travel patterns. This chapter will explore the barriers and motivations to travel for the retired population. Results show that before retirement seniors had less time to travel, obligations at home, and were not interested in as many destinations. After retirement, health barriers negatively impacted an individual’s travel frequency and they were also more concerned about safety while traveling and accessibility to the destinations. After retirement, financial barriers impacted an individual’s domestic travel frequency, with those having lower incomes traveling less. Accessibility to the destination facility and transportation options were major barriers to traveling internationally. Before and after retirement, there was a decrease of 10 percent in international travel.

This study aims at proposing and testing a model delineating how and when the quality of a special B2B professional service, investment relations (IR), would drive corporate intangible value.

This study employs a proprietary dataset on voting records of an annual investment relations (IR) awards event and the corresponding company-level archival data for analysis. Regression analysis is used to test hypotheses.

IR service quality not only directly enhances corporate intangible value, but also indirectly boosts it via information transparency. While competitive intensity does not moderate the relationship between IR service quality and corporate intangible value, its moderating effect on the relationship between information transparency and this value is negative.

The findings advance academic understanding of the mechanism and boundary conditions underlying the complex and dynamic relationships among IR service quality, information transparency, corporate intangible value and competitive intensity. Future research endeavors to verify the present findings in other service and/or geographic settings would help establish their external validity.

The findings advise companies to expand the traditional role of IR by taking it as a powerful communication and relationship marketing tool to improve their visibility and attract investors.

The findings suggest that superior IR service would strengthen the company’s social bonding with institutional investors and effectively signal to them its commitment to good corporate governance practices.

Matching a proprietary dataset on IR voting records with the corresponding company-level archival data over a five-year period to investigate the performance implications of IR service quality within the Hong Kong context rectifies methodological limitation and geographic confinement of prior IR research.

A quick search of the headlines of major newspapers reveals a treasure trove of technology procurement gone wrong. While the private sector seems to adopt and implement new technology seamlessly and quickly to deliver for customers, the government struggles to accomplish technology purchases and integrations with the same ease. As governments in the United States are looking to retain their current workforce and attract the next generation of workers, the technological capabilities and ethos of governments will be paramount. With nearly every industry being transformed by technology and Generation T being the first generation to have an ingrained “technology first” mindset, the ability of governments to attract these workers depends, in large part, on the ability to transform their government technology culture, policies, and practices.

In this chapter, the authors examine the administrative branch and observe two key components at the root of most technology failures: poor organizational structure in the bureaucracy and the lack of an empowered Chief Information/Technology Officer. Building upon case studies from Massachusetts and California, this chapter looks at the factors related to failure or success to understand the technology procurement culture. The chapter concludes by presenting four key “best practice” principles of public policy and administration that can be implemented by almost any governmental entity to improve their acquisition and implementation of technology.

The study analyzes a survey of 372 businesses operating in the East Midlands and reveals the trends of engagement with green growth, demand for green skills development and pro-environmental business support. The findings confirm major differences in how large and small businesses engage with green growth and the challenges they face. Sectorial characteristics are of significance in growth trends and confirm manufacturing companies derive more turnover from the green products when compared to services. Manufacturing companies are also more proactive than services in integrating the green growth ambitions with the business strategy. Green skills and information gaps are major obstacles to business engagement with green growth. Business support agencies are urged to broaden the scope and availability of the pro-environmental enterprise support. Policy community is advised to develop support mechanisms that reduce skills and information gaps. A transformative approach to enterprise support is advocated in order to catalyze the contribution of the business community to sustainable regional development.

Values have long guided special education services and supports for students with extensive support needs; over the past four decades, those values have been backed by research evidence demonstrating the critical nature of values related to inclusive education, self-determination, and seeking strengths and assets. In this chapter, we investigate these values and their supporting research, documenting strengths and needs in extant research. We emphasize the need to continue to embrace and maintain these values while pursuing research that addresses research gaps while centering the priorities, perspectives, and preferences of people with extensive support needs.

Leadership is an essential contributor to employee creative self-efficacy, and past research suggests a positive relationship between servant leadership and creative self-efficacy. However, the relationship is complex and contingent upon moderating variables, and this research examines the moderating effect of role clarity by drawing on social exchange theory and social cognitive theory.

Data collected from a survey among 116 emergency room employees is used to test the research model using moderated ordinary least squares regression.

The results confirm a positive relationship between servant leadership and creative self-efficacy and suggest a U-shaped relationship between role clarity and creative self-efficacy. Furthermore, role clarity positively moderates the relationship between servant leadership and creative self-efficacy.

The sample used for this research mainly consisted of highly educated employees within a specific setting. Future research is needed to study if the relationships found in this research can be generalized to other organizational settings.

This research suggests that leaders can support employees' creative self-efficacy through servant leadership, particularly when coupled with high role clarity.

Rapidly changing work environments are characterized by decreased role clarity, so attention is needed to its moderating role on the relationship between servant leadership and creative self-efficacy.
