This in vitro study aims to explore the effects of selective laser melting (SLM) process parameters on the accuracy of the intaglio surface of cobalt–chromium alloy (Co–Cr), commercially pure titanium (CP Ti) and titanium alloy (Ti–6Al–4V) maxillary removable partial denture (RPD) frameworks and optimize these process parameters.

Maxillary RPD framework specimens designed on a benchmark model were built. The process parameters, including contour scan speed and laser power, infill scan speed and laser power, hatch space, build orientation and metallic powder type, were arranged through the Taguchi design. Three-dimensional deviations of the clasps area, connector area and overall area of maxillary RPD frameworks were analyzed by using root mean square (RMS) as a metric. One-way analyses of variance with the above RMSs as the dependent variable were carried out (α = 0.05).

Maxillary RPD frameworks built horizontally had a more accurate intaglio surface than those built at other orientation angles; CP Ti or Ti–6Al–4V maxillary RPD frameworks had a more accurate intaglio surface than Co–Cr ones; the Maxillary RPD framework built with a higher infill scan speed and lower infill laser power had the more accurate intaglio surface than the one built with other levels of these two process parameters.

A novel benchmark model for evaluating the accuracy of the intaglio surface of maxillary RPD frameworks manufactured by SLM is proposed. The accuracy of the intaglio surface of maxillary RPD frameworks can be improved by adjusting SLM process parameters. The optimal setting of process parameters concerning the accuracy of the intaglio surface of maxillary RPD frameworks was given.

Based on previous inventories, the purpose of this paper is to extend the knowledge on public administration experiments by focusing on their experimental type, design, sample type and realism levels and external validity. The aim is to provide an overview of experimental public administration and formulate potential ways forward.

The authors examine the current state of experimental public administration, by looking at a systematic selection of ISI ranked experimental publications in major public administration journals (1992-2014) and recommend ways forward based on this review.

The review indicates a rise in experimentation in public administration in recent years, this can be attributed mostly to some subfields of public administration. Furthermore, most experiments in public administration tend to have relatively simple designs, high experimental realism and a focus on external validity. Experimental public administration can be strengthened by increasing diversification in terms of samples, experimental designs, experimental types and substantive scope. Finally, the authors recommend to better utilize experiments to generate usable knowledge for practitioners and to replicate experiments to improve scientific rigour.

This paper contributes to experimental public administration by drawing on a systematic selection of papers and assessing them in depth. By means of a transparent and systematic selection of publications, various venues or ways forward are presented.

The aim of this research study is to examine the role of emotional solidarity on religious tourism support. Data for the present research work were attained from various groups of residents in Amasya province/Türkiye.

The Google form-based questionnaires were self-managed by the participants. In the context of the survey, 306 complete questionnaires were gathered. For the data analysis, partial least squares structural equation modeling (PLS-SEM) technique was used via SmartPLS 4.0 software in conjunction with SPSS version 23.

The analysis results show that the emotional solidarity dimensions such as welcoming nature and sympathetic understanding were found to be positively related with religious tourism support at different coefficient levels; however, emotional closeness was not statistically related.

This study adds fresh insights into the field of tourist literature and has beneficial ramifications for business development in the area of religious tourism.

In the context of rewards-based crowdfunding, this study aims to examine the role of project backers as providers of knowledge inputs beyond just financial capital.

This study uses binomial regression to study the relationship between project creators’ and backers’ knowledge sharing, and the relationship of these two knowledge-sharing elements with achieving above-goal funding levels.

This study finds that the project creator’s knowledge sharing is significantly and positively related to backers’ knowledge sharing and that this relationship is moderated by the type of project. Furthermore, backers’ knowledge sharing is positively related to above-goal funding outcomes for a project.

This study established the link between creators’ and backers’ knowledge sharing in rewards-based crowdfunding, which has been underexplored in the literature. This study’s direct attention to the role of knowledge as a key resource in rewards-based crowdfunding and crowdsourcing in general.

For entrepreneurs seeking crowdfunding, this study highlights the importance of knowledge sharing with their project backers to attain above-goal funding. Furthermore, eliciting backers’ knowledge input acts as a signaling mechanism that increases the crowd’s confidence in the project. It also endows entrepreneurs with knowledge resources that can improve project outcomes and achieve broader market success postcrowdfunding.

To the best of the authors’ knowledge, this study is one of the first to focus on knowledge content as a critical element in project backer-creator communication in rewards-based crowdfunding. This study also delineate the various knowledge types shared between the project creator and backers in both rewards-based crowdfunding projects.

Industry descriptions often depict science‐driven industries as a single industry class, dominated by explicit knowledge in the form of patents, blueprints, diagrams, etc. This one‐dimensional view limits our ability to effectively manage the activities and routines across various stages of a science life cycle. The life cycle concept refers to the extent of development of the underlying scientific knowledge base. The knowledge in developed science fields (e.g. chemicals) is well codified, whereas in developing fields (e.g. biotechnology), it is less so. This variance creates interesting implications for innovation – product development routines will differ across developed and developing sciences. The purpose of this paper is to compare and contrast the knowledge‐ and resource‐based requirements of developed and developing science industries and the link to competitive advantage.

There have been a plethora of social science studies of diasporas and immigrants in the USA. Research on Bosnian-Americans, however, has been relatively sparse. The purpose of this study is to understand the relationship between the first-generation Bosnian American's trauma and its transgenerational effects on the second generation.

Bosnian-Americans are a relatively recent immigrant community in the USA, as most of the first-generation immigrated between 1993 and 2002 due to the Bosnian War and its aftermath. This research paper studies second-generation Bosnians to understand transgenerational trauma and emotions carried from the Bosnian War. Through archival research and extended interviews, second-generation Bosnian-Americans were asked questions about Bosnian-American identity and their psychosocial adjustment including transgenerational trauma.

Analysis of the data shows that in the second generation, the psychosocial effects of the Bosnian War have partially been transmitted from the first generation. Understanding the complex constitution of diasporic second-generation identity is facilitated by connecting it to the traumatic backgrounds, life experiences and struggles of the first generation.

The main observation is that there is a transmission of trauma and emotions from the first generation to the second-generation Bosnian Americans, which can be clearly seen in the participants of this research. Forms of transgenerational trauma (e.g. silence) and transmission of emotions (e.g. trust, anger and emotional unavailability) have been a part of the second generation’s lives, which, in fact, shaped their identities and personalities (From my conclusion section).

The purpose of this paper is to propose a national framework for promoting business excellence (NFPBE) using a quality management assessment framework (QMAF) with information knowledge communication (IKC) as an enabler.

The NFPBE using the plan–do–check–act (PDCA) cycle is developed, re-enforcing key quality management aspects/areas including national quality awards, QMAF summary and national innovation programmes using a meta-analysis.

The operationalising of the NFPBE is enabled and supported by an auditing tool to assess the degree of mentoring provided by universities/research institutions/consulting firms to participating firms whose progress will be assessed by the QMAF. It was emphasised that the success of the framework requires the buy-in of national governments to support the programme through stimulus incentives such as government assistance with the costs of research and development, and cooperative research ventures between universities and companies.

The framework is conceptualised into a process flowchart, which is a blueprint to advancing business excellence in organisations at a national scale. The study is limited to only the conceptualisation of the framework. Therefore, an extended study of the framework implementation/application is required for revealing implementation guidelines.

The national framework has a propensity to enhancing the business excellence of organisations at a national level. Therefore, quality managers and policy makers could use the framework to understand the quality management shortfalls and consider strategies to achieving business excellence.

This research study proposed a blueprint to advancing quality excellence in organisations at a national level, guided by several quality frameworks.
