Abstract
Purpose
The purpose of this paper is to empirically determine general models and methods for yield strength and modulus at different print orientations adequate for design purposes associated with typical fused deposition modeled (FDM) components/parts. Emphasis was placed on characterizing the impacts of anisotropy and resulting trends independent of material toward developing a method that matched the level of engineering required for current limited structural capabilities of FDM.
Design/methodology/approach
Tensile tests were performed with a range of unidirectional filament orientations of three different materials allowing for determination of the generalized models, which are then compared to previous findings of others.
Findings
Though anisotropic trends were similar to previous findings, minimum yield strength was found to be associated with filaments 75° from the loading direction resulting in a sinusoidal generalization. Modulus was found to be best approximated with an exponential decay. Resulting models allow for determination of yield strength and modulus in any orientation of FDM-printed material based on minimal testing.
Originality/value
This study is the widest range of angles and materials to be tested and analyzed for unidirectional FDM allowing for new trends to be identified. In line with the level of engineering required for most FDM components/parts, the resulting generalized models allow for determination of yield strength and modulus with less computation and minimal testing.

Abstract
The world of management and technology has become accustomed to the notion of “2.0” advancements and transformative innovations. Is the field of Change Management/Organizational Development itself in this story? Not enough! We re-examine the field’s foundational beliefs, practices, focus, research directions, and value add. We conclude that there is strong evidence from the front line and from an IBM Case Study that the field must “reboot” – to rethink our methods and frameworks; the role and skills of change leadership for the future; change practitioner capabilities for the future; the metrics needed to evaluate progress; and the knowledge exchange between Academe and practitioners.

Abstract
It was not until the late 1960s that housing attracted much attention from academic social scientists. Since that time the literature has expanded widely and diversified, establishing housing with a specialised status in economics, sociology, politics, and in related subjects. As we would expect, the new literature covers a technical, statistical, theoretical, ideological, and historical range. Housing studies have not been conceived and interpreted in a monolithic way, with generally accepted concepts and principles, or with uniformly fixed and precise methodological approaches. Instead, some studies have been derived selectively from diverse bases in conventional theories in economics or sociology, or politics. Others have their origins in less conventional social theory, including neo‐Marxist theory which has had a wider intellectual following in the modern democracies since the mid‐1970s. With all this diversity, and in a context where ideological positions compete, housing studies have consequently left in their wake some significant controversies and some gaps in evaluative perspective. In short, the new housing intellectuals have written from personal commitments to particular cognitive, theoretical, ideological, and national positions and experiences. This present piece of writing takes up the two main themes which have emerged in the recent literature. These themes are first, questions relating to building and developing housing theory, and, second, the issue of how we are to conceptualise housing and relate it to policy studies. We shall be arguing that the two themes are closely related: in order to create a useful housing theory we must have awareness and understanding of housing practice and the nature of housing.

Abstract
In this chapter, I present narratives of two Black men who represent a population of people who are often talked about but seldom heard from in school-to-prison pipeline research. To analyze their stories, I employed a framework that centers on understanding human dignity and the conditions, circumstances, and experiences that threatened it. I found that their sense of self was eroded by moments of personal loss, disposal, and ways that even well-intentioned people marked them as “problems.” I explore how their eroded sense of self led them to engage in disruptive and destructive behaviors. I conclude by discussing the importance of supplementing school-to-prison pipeline research with Black boys’ and men’s first-hand accounts of their own experiences as a way of humanizing the primary subjects of this burgeoning area of education research.

Abstract
Purpose
Despite their documented benefits, evidence-based practices (EBPs) for early childhood social learning are not systematically implemented. Teachers are key players in the implementation process of intervention programs and instructional practices. This is a viewpoint about teachers’ attitudes towards EBPs and their role in the successful implementation of EBPs for early childhood social learning.
Design/methodology/approach
The viewpoint draws on theoretical models of intervention implementation and innovation adoption to explore the importance of individual factors for EBPs implementation and to inform the understanding of the relationship between teachers’ attitudes and EBPs implementation in the context of early childhood social learning. Additionally, it is informed by the literature on research-informed teaching to identify novel opportunities of cultivating positive views towards EBPs for early childhood social learning.
Findings
According to implementation science, in addition to macro-level social and organisation factors, micro-level individual factors that pertain to professionals’ attitudes towards EBPs are related to successful adoption and implementation of EBPs in organisations. Hence, it is important that the investigation of the adoption and implementation of EBPs for early childhood social learning considers the role of teachers’ attitudes towards EBPs. A conceptual model is proposed to explain that research-informed teaching could contribute to fostering positive attitudes towards EBPs for early childhood social learning by raising awareness of the value and potential of research to transform pedagogy.
Originality/value
This viewpoint draws on EBPs implementation science to identify important factors of EBPs adoption and implementation for early childhood social learning that have not been considered extensively and offers a conceptual framework to help understand how research-informed teaching could be an innovative avenue of promoting EBPs implementation in education.

Abstract
Alternative education settings (AES; i.e., self-contained alternative schools, therapeutic day treatment and residential schools, and juvenile corrections schools) serve youth with complicated and often serious academic and behavioral needs. The use of evidence-based practices (EBPs) and practices with Best Available Evidence are necessary to increase the likelihood of long-term success for these youth. In this chapter, we define three primary categories of AES and review what we know about the characteristics of youth in these schools. Next, we discuss the current emphasis on identifying and implementing EBPs with regard to both academic interventions (i.e., reading and mathematics) and interventions addressing student behavior. In particular, we consider implementation in AES, where there are often high percentages of youth requiring special education services and who have a significant need for EBPs to succeed academically, behaviorally, and in their transition to adulthood. We focus our discussion on: (a) examining approaches to identifying EBPs; (b) providing a brief review of EBPs and Best Available Evidence in the areas of mathematics, reading, and interventions addressing student behavior for youth in AES; (c) delineating key implementation challenges in AES; and (d) providing recommendations for how to facilitate the use of EBPs in AES.

Abstract
Purpose
This paper aims to highlight the recruitment practices in the records management (RM) profession in Jamaica’s public sector and their implications for professional practice. This paper is part of a larger doctoral study completed at the University College London that investigated the connection between RM education and national development.
Design/methodology/approach
The research is a qualitative mixed methods study, which mainly utilises data from 34 interviews done among RM practitioners and educators, and development administrators and analysts in Kingston and Spanish Town, Jamaica.
Findings
The study found that there is an urgent need for a change in how RM practitioners are recruited for their roles in Jamaica’s public sector. More coherent frameworks and a more coordinated effort are required to support for the recruitment of practitioners.
Research limitations/implications
This research is specific to the Jamaican case; therefore, it provides little basis for generalisation. Consequently, the study seeks to make no claims that the results in the Jamaican context are generalisable to other societies. Nonetheless, the conclusions and recommendations may be instructive in other environments.
Social implications
The study evaluated some of the existing practices for the recruitment of RM practitioners. As a result, the findings should enhance the knowledge about the human resources needs in RM in Jamaica.
Originality/value
In addition to providing some directions for future research, the study also gives voice to a diverse group. It brings together an analysis of national discourses around RM recruitment practices. This is done through the multifaceted views of Jamaican RM practitioners, development administrators and RM educators represented in the interviews.

Abstract
Purpose
Guided by the salutogenic model of health and well-being, this study aims to use empirical measures of sense of coherence (SOC) and generalized resistance resources (GRRs) to gain a better understanding of the facilitators of successful transition and integration of refugees to Canada and relate these findings to current program development and delivery for the settlement of refugees.
Design/methodology/approach
Survey research and structural equation modeling.
Findings
The authors found that newcomers with a stronger SOC were more likely to report successful integration outcomes. GRRs were found to have both direct and indirect effects on the positive settlement of refugees, with the SOC acting as a strong mediator of indirect effects.
Research limitations/implications
Owing in part, to the disruption caused by the global pandemic, the authors’ data collection period was protracted and the final sample size of 263 is smaller than the authors would have preferred. Another limitation of this study has to do with its cross-sectional design, which limits the articulation of cause-and-effect relationships among the variables.
Practical implications
In terms of program development and delivery for the settlement of refugees, the authors’ results provide further evidence that refugee participation in socially valued decision-making represents a key determinant of healthy resettlement.
Originality/value
Much research on refugee settlement originates within “a pathogenic paradigm” that focuses on the stressors and obstacles encountered by people who have been displaced. Taking its cue from Israeli health sociologist, Aaron Antonovsky’s salutogenic model of health and well-being, this study uses empirical measures of Antonovsky’s interrelated concepts of SOC and GRRs to gain a better understanding of the facilitators of successful transition and integration of refugees to a prairie province in Canada and relate these findings to current program development and delivery for the settlement of refugees.

Abstract
Purpose – This study demonstrates that serious episodes of presidential ill health can have positive impacts on role performance.
Design/methodology – The author utilizes both primary source materials (personal interviews with White House physicians and several other physicians who treated Reagan at the hospital, and the writings of key Reagan aides and family members) and secondary source materials (writings of political scientists, historians, and journalists).
Findings – Reagan was at first in critical condition. It was then that his Secretary of State appeared to make a bold grab for power, an act that contributed materially to the end of his political career. Additionally, the administration’s failure to invoke the presidential disability amendment allowed the official chain of command to be in doubt. Finally, the significant increase in Reagan’s popularity that flowed from his light-hearted demeanor after he was shot is examined here in terms of the President’s subsequent legislative successes.
Originality/value – This study suggests strongly that Reagan’s impressive legislative achievements in mid-1981 were due significantly to his heroic response to having been shot.
