Abstract

Conventional shaping processes for ceramics are mostly based on a powder‐technological molding process using a negative mold and subsequent thermal compaction. Especially for prototypes and small lot series of microcomponents the outlay for molds are the major costing factor. Consequently the use of rapid prototyping (RP) processes can decisively reduce the costs and time in product development of ceramic microcomponents. In spite of the fact, that a large number of freeform fabrication techniques for different materials were developed in recent years, most generative techniques of ceramics still have different drawbacks for the fabrication of prototypes and often exhibit limited resolution compared to those of polymers. The combination of RP techniques such as micro stereolithography and ceramic injection molding in a RP process chain can fill in the gap between the limited applicability of solid freeform fabrication of ceramics and the restricted material properties of polymers.

Abstract

Purpose

The purpose of this paper is to test the effect of human resource systems on organization attraction. Furthermore, the authors theorize and test how the vocational interests of prospective employees can serve as boundary conditions that affect the relationship between high-performance work systems (HPWS) and organization attraction.

Design/methodology/approach

To achieve these ends, this study conducts a scenario-based experiment with prospective employees to examine the effects of HPWS and vocational interests on organization attraction.

Findings

The authors demonstrated that HPWS is an important feature for organization attraction. Despite the generally positive linkage between HPWS and organization attraction, the most important implication of the findings is that job applicants also have an important role in responding to the features being used by a firm to attract applicants through HPWS. For example, potential job applicants with higher (rather than lower) social vocational interests are more likely to be attracted to the HPWS of firms.

Research limitations/implications

This study has limitations that must be considered. In particular, the authors treated HPWS as a unidimensional construct. Given the study design, it is unclear whether the attraction effects are driven by HPWS as a whole or whether they are being driven by any single or multiple component(s) of the system. Future research needs to consider examining how specific practices are matched with specific vocational interests by using multiple scenarios where they bundle different high-performance work practices. Doing so would further the understanding of which specific practices affect attraction and for whom.

Originality/value

This study contributes to the authors’ knowledge of the effects of HPWS on organization attraction. In addition, job applicants’ social vocational interest plays an important role in strengthening the relationship between HPWS and organization attraction.

Abstract

Purpose

This paper aims to explore the limitations of the conformal finite difference time-domain method (C-FDTD or Dey–Mittra) when modeling perfect electric conducting (PEC) and lossless dielectric curved surfaces in coarse meshes. The C-FDTD is a widely known approach to reduce error of curved surfaces in the FDTD method. However, its performance limitations are not broadly described in the literature, which are explored as a novelty in this paper.

Design/methodology/approach

This paper explores the C-FDTD method applied on field scattering simulations of two curved surfaces, a dielectric and a PEC sphere, through the frequency range from 0.8 to 10 GHz. For each sphere, the mesh was progressively impoverished to evaluate the accuracy drop and performance limitations of the C-FDTD with the mesh impoverishment, along with the wideband frequency range described.

Findings

This paper shows and quantifies the C-FDTD method’s accuracy drops as the mesh is impoverished, reducing C-FDTD’s performance. It is also shown how the performance drops differently according to the frequency of interest.

Practical implications

With this study, coarse meshes, with smaller execution time and reduced memory usage, can be further explored reliably accounting the desired accuracy, enabling a better trade-off between accuracy and computational effort.

Originality/value

This paper quantifies the limitations of the C-FDTD in coarse meshes in a wideband manner, which brings a broader and newer insight upon C-FDTD’s limitations in coarse meshes or relatively small objects in electromagnetic simulation.

Abstract

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Abstract

Purpose

The purpose of this paper is to propose a model that explains how proactive cognitive processes, such as perspective-taking, relates to expatriates’ effectiveness.

Design/methodology/approach

This conceptual paper presents the model that is based on the perspective-taking models developed by Parker et al. (2008) and applies them to the expatriate context.

Findings

The authors present a framework that delineates how the perspective-taking process leads to an expatriate’s effectiveness. The authors provide propositions about which factors motivate expatriates to engage in perspective-taking and which factors influence higher accuracy of understanding of the host country nationals’ (HCN) perspective.

Practical implications

Guidance is provided for the training of expatriate to develop perspective-taking.

Originality/value

The paper expands the expatriate research by incorporating the perspective-taking model to identify which factors may motivate expatriates to see the HCN view point. Also, the paper contributes to the literature by identifying how resources such as expatriates’ psychological capital may promote the degree of accuracy or comprehension with respect to the HCN thoughts and feelings.

Abstract

Purpose

The purpose of this paper is to employ a mixed methods design to assess the applicability, reliability and validity of Miller's scale of environmental uncertainty.

Design/methodology/approach

Using 759 questionnaires and eight personal interviews from three countries throughout four phases of scale assessment, the authors re‐operationalized Miller's scale to be more applicable to Arab countries. Phase 1 refines the scale with reference to the new context in which the authors applied it. Phase 2 eliminates poor performing items, using exploratory factor analysis. Phase 3 examines the generalizability of the modified scale in the Arab world. Finally, Phase 4 assesses the criterion‐related validity of the scale.

Findings

The authors' assessment of Miller's scale suggests that several changes in the scale are necessary to be more applicable in Arab countries. The results of the combined sample are consistent with the hypothetical structure of constructs and have four factors: product, competition, government and policies, and economy.

Originality/value

This study paid attention to the conceptualization and operationalization of strategic management research variables. Moreover, examining the Miller's scale in the Arab region could enhance the generalizability of this scale. Finally, the authors' longitudinal research, with its four samples, is another contribution.

Abstract

Purpose

The purpose of this paper was to describe the research literature on the science of children's resilience and show its application to parenting interventions for high-risk families. Information about the design and conduct of pilot work to develop a parent program with homeless mothers was included to illustrated this application.

Design/methodology/approach

The design of this report was descriptive. The scientific rationale for promoting children's resilience. The scientific rationale for strengthening children's resilience by focusing on parent's promotion of attachment, executive function skills, and stress/reduction mindfulness was detailed, and the design and format of a pilot parent program was outlined.

Findings

Substantial research evidence affirmed the importance of strengthening children's resilience in high-risk families. Details from pilot work with homeless mothers illustrated the process by which activities were included in workshops to promote children's resilience. Future work will test the efficacy of this program in a controlled study with a range of pre- and post-assessments.

Practical implications

The current paper expanded the traditional focus of parent education to include strengthening children's resilience as a way to better address the myriad of critical needs faced by children and families experiencing homelessness.

Originality/value

The design and format of a community-based parenting program to strengthen children's resilience by focusing on attachment, executive function skills, and stress reduction/mindfulness were novel. Future research will test the efficacy of this new program with high-risk families.
