This paper aims to present an investigation into the variation of scan vector hatch rotation strategies in selective laser melting (SLM), focussing on how it effects density, surface roughness, tensile strength and residual stress.

First the optimum angle of hatch vector rotation is proposed by analysing the effect of different increment angles on distribution of scan vectors. Sectioning methods are then used to determine the effect that the chosen strategies have on the density of the parts. The top surface roughness was analysed using optical metrology, and the tensile properties were determined using uni-axial tensile testing. Finally, a novel multi-support deflection geometry was used to quantify the effects of rotation angles on residual stress.

The results of this research showed that the hatch rotation angle had little effect on the density, top surface roughness and strength of the parts. The greatest residual stress deflection was measured parallel to unidirectional scan vectors. The use of hatch rotations other than alternating 90° showed little benefit in lowering the magnitude of residual stresses. However, the use of rotation angles with a good suitability measure distributes stresses in all directions more evenly for certain part geometries.

All samples produced in this work were made from commercially pure titanium, therefore care must be taken when applying these results to other materials.

This paper serves to increase the understanding of SLM scanning strategies and their effect on the properties of the material.

This article informs school leaders and staffs about existing research findings on the use of data-driven decision-making in creating class rosters. Given that teachers are the most important school-based educational resource, decisions regarding the assignment of students to particular classes and teachers are highly impactful for student learning. Classroom compositions of peers can also influence student learning.

A literature review was conducted on the use of data-driven decision-making in the rostering process. The review addressed the merits of using various quantitative metrics in the rostering process.

Findings revealed that, despite often being purposeful about rostering, school leaders and staffs have generally not engaged in data-driven decision-making in creating class rosters. Using data-driven rostering may have benefits, such as limiting the questionable practice of assigning the least effective teachers in the school to the youngest or lowest performing students. School leaders and staffs may also work to minimize negative peer effects due to concentrating low-achieving, low-income, or disruptive students in any one class. Any data-driven system used in rostering, however, would need to be adequately complex to account for multiple influences on student learning. Based on the research reviewed, quantitative data alone may not be sufficient for effective rostering decisions.

Given the rich data available to school leaders and staffs, data-driven decision-making could inform rostering and contribute to more efficacious and equitable classroom assignments.

This article is the first to summarize relevant research across multiple bodies of literature on the opportunities for and challenges of using data-driven decision-making in creating class rosters.

Medical students experience higher rates of mental illness than the general population. With competition rising for success in medical school, and residency, increasing incidence of distress are leading this population to experience higher rates of thoughts of dropping out of school, and even suicide. Since many stigmas deter medical students from receiving mental health counseling, such as the perceived inability to handle the stresses of medical school, and the potential lack of competitiveness for residencies if reported, prevention of mental illness may be a better course to take in reducing prevalence in this population. Regular exercise has demonstrated a positive effect on not only promoting physical health, but also mental health. Exercise encourages a healthy mood, positive self esteem, and better cognition, while decreasing the chances of depression, anxiety, and burnout. Implementing exercise time into medical school curriculums, just like the basic sciences, albeit for less time in the day, could provide a feasible way to ensure that all students are taking time to partake in this important activity for their well being. Though medical schools are rigid with attempts to make changes in their curriculum, thirty minutes a day, three to five times a week of exercise of the students' choice not only is more cost effective than counseling, but it also reduces the chances that they will experience burnout, which if left untreated could transcend into a compromised training experience.

This study aims to examine the relationships between personal (emotional intelligence, Dark Triad (DT), core self-evaluation and burnout) and situational variables (organizational justice) and organizational citizenship behavior (OCB) (supervisor report) and counterproductive work behavior (CWB) (self-report).

In total, 680 questionnaires were distributed to teachers in 20 Arab elementary schools in Northern Israel. Usable questionnaires were returned by 509 teachers (75%). The questionnaires covered emotional intelligence, DT, core self-evaluation, organizational justice, burnout, CWB and demographic characteristics. Their principals filled out questionnaires on the teachers’ in-role performance and OCB.

Results showed that CWB was mostly related to higher levels of psychopathy, lower levels of emotional intelligence (ability to use emotions) and higher levels of burnout (emotional exhaustion). OCB was related to higher levels of procedural justice, lower levels of burnout and higher levels of emotional intelligence.

Organizations should consider ways to reduce burnout, which may reduce CWB and increase perceptions of justice, thereby promoting OCB.

Two novel aspects are noteworthy. First, this study simultaneously examines both CWB and OCB to clarify the similarities and differences between them. Second, few studies have examined the correlates of CWB and OCB in Arab culture.

In the early to mid-twentieth century, psychiatrist-led occupational therapy departments emerged in Irish psychiatric hospitals. This marked a transition towards establishing rehabilitative services in institutional settings. This paper aims to examine the development of occupational therapy in Grangegorman Mental Hospital and its auxiliary hospital, Portrane Mental Hospital from 1934-1954.

Historical documentary research methods were used to analyse primary source data from Grangegorman Committee Minutes, Inspector of Mental Hospital Reports, Boroughs of Mental Hospitals, Department of Foreign Affairs documents and newspaper archives. The archival data was analysed using both a chronological and thematic approach.

The main key event emerged in 1935 when four Grangegorman nursing staff were sent to Cardiff Mental Hospital to undergo a six month training course in occupational therapy. The following themes emerged – “establishing occupational therapy in Grangegorman and Portrane”; “the role of short-course trained nursing staff in providing occupational therapy services” and “therapeutic rationales vs hospital management rationales”.

This study throws light on the early practitioners of occupational therapy in Grangegorman and highlights the complexities of occupational therapy’s role origins in mid-twentieth century Ireland. In line with contemporaneous psychiatric hospitals, the occupational therapy activities promoted in Grangegorman were mainly handicraft or productivity based. The absence of patients’ voices means there are limitations to determining the therapeutic nature of this early occupational therapy service.

The purpose of the paper “Commerce, jobs and politics: the impact of the USA–China trade on USA domestic politics” is to examine the impact of Chinese trade with the USA to determine the consequences of the trade on manufacturing employment. The geographic and sectoral impacts of this trade are assessed. The conclusion is that the USA–China trade has affected political polarization in such a way as to affect electoral outcomes. Implications for policy are discussed in the paper.

The overall design is a focused case study in terms of its focus on the USA–China trade relations. There is also a statistical component due to the breakdown of the USA in economic commuting zones.

The major finding is that Chinese import penetration created substantial political polarization in the USA and that polarization affected electoral outcomes. Chinese import penetration also resulted in a shift of jobs from the eastern heartland to the coasts. Much of the transition was aided by the restructuring of jobs within firms from manufacturing to high-end services.

Perhaps, the biggest limitation concerns how general and durable the findings are. The authors establish that the first decade after Chinese entry into the World Trade Organization (WTO) (2001) was characterized by economic disruption in the USA labor market. Whether the economic effects will have a longer duration is not known.

One practical limitation is that it is difficult to know what policy actions to take on the basis of the research: trade policy, human capital (education) policy or place-based policies which aid particular regions.

The social implications in this paper are jobs and employment policy.

The author thinks this is very original work, though based on the work of several economists. But outside of a few articles, the author does not think much has appeared in political science journals.

The purpose of this paper is to investigate the extent to which the organizational commitment and job satisfaction influence intent to turnover.

Following a quantitative approach regarding methodological aspects of this research, a case study was carried out in a company of information technology and communication located in Porto Digital, in the Northeast of Brazil. A data collection technique with 172 forms, a self-administered form with 18 closed questions with a Likert-type scale and an open questionnaire were used. In this analysis, Statistical Package for the Social Sciences (SPSS) software was used as the technique; besides the descriptive statistics, a correlation was made between dependent variables (intention of rotation) and independent variables (affective, normative, instrumental and work satisfaction). The level of organizational commitment in its three dimensions (affective, normative and instrumental), the job satisfaction in its five dimensions (satisfaction with nature of the task, with leadership, with colleagues, with salary and promotions) and the level of intent to turnover from the respondents were investigated.

The results suggest that affective and normative commitments and satisfaction with pay, satisfaction with promotions and satisfaction with the nature of the work are correlated with the intention of negative turnover significantly. Among the demographic factors, only the age showed a negative correlation with intent to turnover. By performing multiple regression analysis, we identified that the variables that most impacted the turnover intention are affective commitment, satisfaction with salary and normative commitment. The qualitative portion of this study was accomplished through a content analysis of the open question of the form. Finally, one of the main considerations is the findings that revealed variables other than those adopted in the study, which influence the permanence of the respondents.

Among the limitations of the research a single case study is highlighted that replicates the experience in other ICT companies to verify if the results found are similar in other organizations and in other segments. The findings direct the construction and validation of new scales, the creation of qualitative protocols to identify the variables that influence the retention of a specific group of individuals to serve as a guide for the elaboration of a questionnaire, as well as creation of surveys of longitudinal nature to correlate the data of intention of rotation with the effective turnover.

Based on the results, organizations can reduce voluntary evasion by adjusting actions, policies and practices, directing those responsible for People Management to attract and retain good employees. It should be emphasized that voluntary turnover should be treated as one of the management indicators of greater relevance by organizations, representing a thermometer of all human capital management.

The monitoring of employment and unemployment levels is part of the public policy agenda for generating employment and income in Brazil. For organizations, employee turnover can and should be managed and monitored so that appropriate levels are found and their consequences are minimized through effective solutions. The results are important both for technology-based organizations and for all stakeholders interested in the subject as the public power.

Although in the international literature turnover is a topic of study for many years, in the Brazilian context, there is a shortage of research on the subject, specifically in the sector of advanced technology where there is a great lack of skilled labor, a fierce competition and where to keep employees standard high becomes a survival factor. This study may contribute to the exploration in the local literature, as it will help locate the academy on the Brazilian reality and open the doors to new research works on turnover and its possible correlations with other variables besides organizational commitment and job satisfaction.

Misinformation is a significant phenomenon in today's world: the purpose of this paper is to explore the motivations behind the creation and use of misinformation.

A literature review was undertaken, covering the English and Russian language sources. Content analysis was used to identify the different kinds of motivation relating to the stages of creating and communicating misinformation. The authors applied Schutz's analysis of motivational types.

The main types of motivation for creating and facilitating misinformation were identified as “in-order-to motivations”, i.e. seeking to bring about some desired state, whereas the motivations for using and, to a significant extent, sharing misinformation were “because” motivations, i.e. rooted in the individual's personal history.

The general model of the motivations underlying misinformation is original as is the application of Schutz's typification of motivations to the different stages in the creation, dissemination and use of misinformation.

Adequate recovery from burnout is important to understand. The purpose of this paper is to investigate whether post-traumatic growth (PTG) contributes to higher engagement and reduced symptoms of burnout and whether this process is mediated by personal resources.

In a cross-sectional survey, 166 Dutch workers who had fully recovered from burnout were questioned on their level of PTG, their personal resources (optimism, resilience and self-efficacy), and their levels of engagement and burnout.

Fully recovered workers scored somewhat higher on current burnout level, but did not differ from norm group workers in their engagement level. Moreover, PTG appeared to positively affect both higher engagement and lower burnout levels, which is fully mediated by personal resources.

Post-traumatic growth (PTG) impacts on engagement and burnout levels amongst workers who have recovered from burnout by enhancing personal resources. The role of personal resources and the impact of PTG on engagement and burnout complaints following (recovery from) burnout deserve further investigation.

Management can support workers who have (recovered from a) burnout, by being aware of their (higher) engagement, and facilitate the enhancement of PTG and personal resources.

This study is one of the first to study the role of PTG after (recovery from) burnout and reveals valuable findings for both research and practice.

A decade after Powell et al.’s (2011) seminal article on behavioral strategy, which called for models to solve real-world problems, the authors revisit the field to ask whether behavioral strategy is coming of age. The purpose of this paper is to explain how behavioral strategy can and has been used in real-world settings.

This study presents a conceptual review with case study examples of the impact of behavioral strategy on real-world problems.

This study illustrates several examples where behavioral strategy debiasing has been effective. Although no causal claims can be made, with the stark contrast between the negative impact of biased strategies and the positive results emerging from debiasing techniques, this study argues that there is evidence of the benefits of a behavioral strategy mindset, and that this should be the mindset of a responsible strategic leader.

This study presents a demonstration of analytical, debate and organizational debiasing techniques and how they are being used in real-world settings, specifically military intelligence, Mergers and acquisitions deal-making, resource allocation and capital projects.

Behavioral strategy has broad application in private and public sectors. It has proven practical value in various settings, for example, the application of reference class forecasting in large infrastructure projects.
