This paper aims to study the effect of processing parameters and the fundamental mechanism of surface morphologies during electron beam selective melting.

From the powder-scale level, first, the discrete element method is used to obtain the powder bed distribution that is comparable with the practical condition; then, the finite volume method is used to simulate the particle melting and flowing process. A physically reliable energy distribution of the electron beam is applied and the volume of fluid method is coupled to capture the free boundary flow. Twelve sets of parameters grouped into three categories are examined, focusing on the effect of scan speed, input powder and energy density.

According to the results, both melting pool width and depth have a positive relation with the energy density, whereas the melting pool length is insensitive to the scan velocity change. The balling effect is attributed to either an insufficient energy input or the flow instability; the hump effect originates from the mismatch between electron beam moving and the fluid flow. The scan speed is a key parameter closely related to melting pool size and surface morphologies.

Through a number of case studies, this paper gives a comprehensive insight of the parameter effects and mechanisms of different surface morphologies, which helps to better control the manufacturing quality of electron beam selective melting.

This paper aims to assess the effects of explicit partner brand mentions (as opposed to a mere partnership mention) in communications by brand allies on consumers’ purchase intention and willingness to pay for an innovation, as mediated by the perceived relational embeddedness of the allies and their respective perceived corporate credibility. In Study 1, the authors investigate the effects of (reciprocal) explicit brand mentions by both allies (as opposed to by a single ally) and further test whether explicit brand mentions moderate spillover effects from the ally. In Study 2, the authors investigate the effect of reciprocity of explicit brand mentions and whether this is moderated by a company’s experience.

The authors conduct two online experiments. Study 1 (N = 216) is a four-level between-subjects experiment (single communication by Partner A with explicit brand mention, single communication by Partner B with explicit brand mention, explicit brand mentions by both allies and mere partnership mention by both allies) where participants judge a social alliance related to a new tablet. Study 2 (N = 376) builds upon these findings in a 4 (explicit brand mentions by both allies; mere partnership mention by both allies; explicit brand mention by Partner A, mere partnership mention by Partner B; explicit brand mention by partner B, mere partnership mention by Partner A) × 2 (Partner A experience: established vs startup) between-subjects experimental design for a co-created battery.

Spillover effects from one ally to the other are stronger with explicit brand mentions than with a mere partnership mention. There is no added value of two allies communicating over one, provided that both partners explicitly mention their partner brand. However, when allies do communicate separately, it is crucial that an explicit brand mention is reciprocated. This effect is explained by an increase in the perceived relational embeddedness of the partners, which in turn positively influences their corporate credibility. This effect does not differ depending on a company’s experience.

This research is one of the first to study effects of how a brand alliance is communicated and extends previous studies on the effects of communication about brand and co-creation alliances by demonstrating that communications moderate spillover effects, that brand mention reciprocity is crucial, and by introducing the concept of perceived relational embeddedness.

In debates related to energy poverty, the link to questions of residential segregation remains somewhat peripheral. Because, usually, only energy-poor households are at the focus and residential mobility is not addressed, the interdependencies between households’ energy costs and the residential segregation of cities remain out of sight. Concern that energy efficiency measures could foster socio-spatial segregation in cities has recently emerged in Germany. If only households with higher incomes can afford housing with high energy efficiency standards, whereas low income households tend to choose non-refurbished but, in sum, more affordable housing stock, an increasing concentration of poor households in poor housing conditions would result. German energy efficiency and CO2 reduction policies are relatively insensitive to such questions.

Using survey data from a small shrinking city in Germany, we explore how energy costs are interrelated with residential location decisions and, thus, with segregation processes and patterns. Shrinking cities represent an interesting case because, here, a decreasing demand for housing stimulates residential mobility and paves the way for dynamic reconfigurations of socio-spatial patterns.

We found that energy-related aspects of homes play a role in location decisions. Low income households seek to minimize housing costs in general, paying specific attention to heating systems, thermal insulation and costs. Resulting segregation effects depend very much on where affordable and, at the same time, energy-efficient housing stock is spatially concentrated in cities. These findings should be taken into consideration for future policies on energy in existing dwellings.

Considerably diminished quality of life (QoL) is observed in patients with visual field defects after lesions affecting the visual pathway. But little is known to what extent vision-and health-related QoL impairments are associated with psychological distress. In 24 patients with chronic visual field defects (mean age=56.17±12.36) the National Eye Institute-visual functioning questionnaire (NEI-VFQ) for vision-related QoL, the Short Form Health Survey-36 (SF-36) for generic QoL and the revised Symptom-Checklist (SCL-90-R) were administered. Cases with clinically relevant SCL-90-R symptoms were defined. Demographic, QoL and visual field parameters were correlated with SCL-90-R scales. About 40% of the investigated patients met the criteria for the definition of psychiatric caseness. 8/12 NEI-VFQ scales correlated significantly with SCL-90-R phobic anxiety (r-range -0.41 to -0.64, P<0.05), 5/12 NEI-VFQ scales correlated with SCL-90-R interpersonal sensitivity (-0.43 to -0.50), and 3/12 with SCL-90-R depression (-0.51 to -0.57) and obsessive-compulsiveness (-0.41 to -0.43). In contrast, only 1/8 SF-36 scales correlated significantly with SCL-90-R depression, phobic anxiety and interpersonal sensitivity (-0.41 to -0.54). No substantial correlations were observed between visual field parameters and SCL-90-R scales. Significant correlations of SCL-90-R with NEI-VFQ but not with SF-36 suggest that self-rated psychological distress is the result of diminished vision-related QoL as a consequence of visual field loss. The extent of visual field loss itself did not influence the rating of psychological distress directly, since SCL-90-R symptoms were only reported when diminished vision-related QoL was present. Patients with reduced vision-related QoL due to persisting visual field defects should therefore be offered additional neuropsychological rehabilitation and supportive psychotherapeutic interventions even years after the lesion.

A prolific stream of research has demonstrated the unique potential of sports sponsorship to contribute to corporate image and to influence audiences around the world. Meanwhile, the concept of corporate social responsibility (CSR) has increasingly been identified in the literature for its potential to deliver a degree of competitive advantage. This paper builds on both these theoretical fields to develop a conceptual framework linking the effectiveness of sports sponsorship with the sponsors' CSR commitment to both employees and consumers.

The purpose of this study is to examine the underexplored link between entrepreneurship education (EE) and graduate employability in the higher education (HE) sector in the United Kingdom (UK).

The study draws on a thematic content analysis of semi-structured interviews with 45 professionals in UK HE, representing the “supply” side of EE.

The findings demonstrate a unidirectional link between EE and employability outcomes. This link is affected by societal, stakeholder-related, and teaching and learning-related factors.

Although the value of universities’ initiatives connecting EE and employability for economic development is emphasized, the study does not provide direct empirical evidence for this effect. Macroeconomic research is needed.

EE and employability would benefit from knowledge exchange between universities’ stakeholders and a broader understanding of what constitutes a valuable graduate outcome.

The study reveals the benefits of EE on a micro level. Participation in EE supports the connection between individual investments in HE and employability.

Based on human capital theory, many policymakers regard EE as a vehicle through which the relationship between investments in HE and career success on a micro level and economic growth on a macro level can be nurtured. Challenging this logic, the study highlights the potential of institutional theory to explain a contextualization of the link between EE and employability on a national level.

The purpose of this study is the introduction and validation of a new technique for process monitoring during electron beam melting (EBM).

In this study, a backscatter electron detector inside the building chamber is used for image acquisition during EBM process. By systematic variation of process parameters, the ability of displaying different topographies, especially pores, is investigated. The results are evaluated in terms of porosity and compared with optical microscopy and X-ray computed tomography.

The method is capable of detecting major flaws (e.g. pores) and gives information about the quality of the resulting component.

Image acquisition by evaluating backscatter electrons during EBM process is a new approach in process monitoring which avoids disadvantages restricting previously investigated techniques.

Combining institutional work and actor engagement (AE) literature, this paper aims to elucidate how the collective action of market shaping occurs through the interplay between market shapers’ institutional work and engagement of other market actors. While markets are shaped by actors’ purposive actions and recent literature notes the need to also mobilize AE, the underlying process remains nebulous.

This paper is conceptual but supported by an illustrative case study: the Winding Tree. This blockchain-based, decentralized travel marketplace shapes a market by decoupling existing resource linkages, creating new ones and stabilizing others through a dynamic, iterative process between the market shaper’s institutional work and others’ AE.

The paper develops a dynamic, iterative framework of market shaping through increased resource density, revealing the interplay between seven types of market shapers’ institutional work distilled from the literature and changes in other market actors’ engagement dispositions, behaviors and the diffusion of AE through the market.

This research contributes to the emergent market shaping and market innovation literature by illustrating how the engagement of market actors is a fundamental means of market shaping. Specifically, it advances understanding of how market shapers’ institutional work leads to new resource linkages and higher resource density in emergent market systems through AE. The resultant framework offers an original, critical foundation for future market shaping research.

The shift in policy discourse towards individualism is affecting service provision and access, which has become increasingly conditioned on individual agency and the “deservingness” of the recipient. Gendered and intersectional experiences of homelessness and excluded populations less likely to be living on the streets remain overlooked and unaddressed. This study thus aims to uncover what drives “invisibility” in services for women experiencing multiple disadvantage and the gendered constraints the women are facing when exiting and navigating multiple disadvantage.

The paper draws on in-depth interviews with women who face severe and multiple disadvantage and their support staff. Data is also gathered through survey data and observations with a wide range of frontline service providers, as well as support notes and numerical progress data recorded by one of the service providers.

Contradicting the common assumption that people act as rational actors in their interaction with services, the author found that women’s decisions to (dis)engage may be blinded by forces of multiple disadvantage and mistrust. These are often developed as a result of systemic and gendered constraints that limit women’s capabilities and exercise of choice. Barriers in service access often amplified the personal barriers they were facing and reinforced women’s decisions to not engage with services.

The author hopes that this paper sheds light on the particular set of barriers women with multiple disadvantage face, which will be vital to reach women who face severe disadvantage and provide more effective policies, care and support.

This study gives voice to a particular hidden population: women with multiple disadvantage. It contributes to existing frameworks on agency and choice by understanding gendered barriers behind service engagement and how services themselves may be contributing to women’s invisibility.

Customer engagement is of critical interest to both academics and practitioners. Extant literature focusses primarily on customer engagement with a single focal object, usually brands; this study takes another view to consider customer engagement with multiple focal objects (service provider and context). In addition to testing the relationship of the individual dimensions of engagement with the service provider and engagement with the context, this research elaborates on their drivers, with a particular focus on distinct engagement platforms. The paper aims to discuss these issues.

A survey captures customer engagement with a service provider and a context in a higher education setting, with 251 responses collected across first- and third-year marketing courses in an Australian, mid-sized university.

Engagement with the service provider can drive engagement with the context. In turn, engagement with the service provider can be stimulated through the use of engagement platforms that enable customer-to-service provider interactions. The results show limited effects of customer-to-customer engagement platforms on engagement with the context though. The results are consistent across gender and student grade levels; some differences arise between international and domestic students.

This unique study broadens understanding of customer engagement with various focal objects and also details the flow of effects, from engagement with a service provider to engagement with the context. This research builds on conceptual discussions of engagement platforms and empirically examines their ability to facilitate affective, cognitive and behavioural engagement.
