Abstract

Purpose

Microstructure-sensitive design (MSD), for optimal performance of engineering components that are sensitive to material anisotropy, has largely been confined to the realm of theory. The purpose of this paper is to insert the MSD framework into a finite element environment in order to arrive at a practical tool for improved selection and design of materials for critical engineering situations.

Design/methodology/approach

This study applies the recently developed Hybrid Bishop-Hill (HBH) model to map the yield surface of anisotropic oxygen free electronic copper. Combining this information with the detailed local stresses determined via finite element analysis (FEA), a “configurational yield stress” is determined for the entire component. By varying the material choice/processing conditions and selecting the directionality of anisotropy, an optimal configuration is found.

Findings

The paper provides a new FEA-based framework for MSD for yield-limited situations. The approach identified optimal directionality and processing configurations for three engineering situations that are particularly sensitive to material anisotropy.

Research limitations/implications

The microstructure design space for this study is limited to a selection of eight copper materials produced by a range of processing methods, but is generalizable to many materials that exhibit anisotropic behavior.

Originality/value

The introduction of MSD methodology into a finite element environment is a first step toward a comprehensive designer toolkit for exploiting the anisotropy of general materials (such as metals) in a way that is routinely undertaken in the world of fiber-based composite materials. While the gains are not as sizeable (due to the less-extreme anisotropy), in many applications they may be extremely important.

Abstract

Purpose

The purpose of this paper is to help in providing a better understanding on knowledge sharing amongst academics in higher education institutions (HEIs). The aim of this study is realized by profiling existing literature to understand the determinants of knowledge sharing, research trends, theories, and future research opportunities.

Design/methodology/approach

After carefully examining the extant literature and by utilizing relevant academic-based research databases, a total of 73 papers published in peer-reviewed journals over the last decade were reviewed and analyzed using well-established systematic literature review methodology.

Findings

The adopted systematic review revealed that there are limited contributions in understanding knowledge sharing in HEIs when compared with other sectors. The review provides a number of avenues for future research including technological, cultural, organizational, and behavioral aspects at different levels.

Practical implications

This study helps in offering a focal point to senior management in HEIs for realizing the requirements for developing appropriate strategies and programs to promote knowledge sharing among academics and consequently enhance their institutions’ performance.

Originality/value

This study utilized Jesson et al. (2011) in presenting a comprehensive systematic review of knowledge sharing specifically in the context of HEIs. This paper offers some theoretical and practical insights on what contributes toward understating the determinates affecting knowledge sharing practices among academics.

Abstract

Purpose

The purpose of this paper is to explore the relationship between the availability and use of IT solutions for strategic knowledge management (SKM) and the universities’ performance, measured in terms of scientific production.

Design/methodology/approach

Drawing on the resource-based view (RBV) and the knowledge-based theory, the authors develop a conceptual framework for exploring the effect of SKM based on IT on the organisation’s performance that they empirically test by applying panel data methodology to a sample of 70 Spanish universities over the period 2011-2014.

Findings

The authors confirm that the SKM based on IT influences the university’s performance. This effect is positive in the case of the IT solutions referred to the infrastructure of data grouping and more evident when the university’s performance is measured by indicators more directly related to scientific quality. Contrary to expected, the percentage of training and research staff that uses institutional tools of collaborative work is negatively related with the universities’ capacity of publication.

Practical implications

The authors followed the system dynamics approach to identify a causal diagram and a flow sequence that lets them group universities in three different profiles in the knowledge management (KM) flow diagram.

Originality/value

First, the authors develop a conceptual framework for exploring the effect of SKM based on IT on the organisation’s performance that could be applicable to analyse the case of other knowledge-driven organisations. Second, in contrast with the large number of studies dealing with SKM and performance focused on firms, the authors analyse universities. Third, the authors’ empirical approach used the panel data methodology with a large sample of universities over the period 2011-2014.

Abstract

In an address to the East India Association Sir John Woodhead drew upon his experience as chairman of the Famine Inquiry Commission to review in authoritative fashion what Lord Scarborough described from the chair as one of the most important requirements of to‐day, that of increasing the food supplies and improving the diet of the people of India. Of the present population of about 400,000,000, it has been estimated that fully one‐third are under‐nourished, while a still larger proportion are ill‐nourished for lack of a balanced diet. The staple articles of diet are rice, wheat and millet, and even when these are consumed in adequate quantities their deficiencies in proteins, fats, vitamins, and mineral salts must be made good by protective foods. The technological possibilities of increasing food production are very great. It is known that the yield of rice can be increased by anything up to one‐half by manuring and by the use of improved strains; and that potential increases in millet and wheat are of the order of 30 per cent. The Famine Inquiry Commission concluded that self‐sufficiency in cereals was practicable as well as desirable as a policy for the future, and that a large increase in protective and supplementary foods, such as pulses, vegetables, fruit and fish was entirely feasible. Nor is there any mystery as to how the increase is to be achieved. The methods which must be followed, such as the provision of an assured water supply, the utilisation of every source of fertilising material, the cultivation of improved strains of plants and beasts, the protection of husbandry from pests and of the husbandman from ill‐health—all these are familiar in plans for the improvement of the rural economy of India. What is novel, however, is the increasing recognition that only a concerted effort, on a national scale, employing the resources of the people and of the Government in close partnership, can avail to raise the Indian masses from ramshackle medievalism to ordered, progressive modernity. Improvement of diet is among the most important elements in that improvement of the standard of living which is the principal object of all Indian planning to‐day. At present, lack of purchasing power is the root of malnutrition as of many other evils; increased agricultural production and a better diet arc bound up with the process of increasing the national wealth through simultaneous industrial development. Urbanisation and higher living standards may in turn exert their influence upon the growth of population; for Sir John Wood‐head's commission found that among the upper and professional classes the birth‐rate is falling steadily. Throughout the whole population, indeed, the birth‐rate fell from 34 a thousand in 1940 to 26 a thousand in 1943; but this decline may be due to transient causes only. There seemed good grounds for hoping that the future pressure of population need present no immovable obstacle to the success of a really national movement for better livelihood.

Abstract

Purpose

Higher education institutions, particularly in developing countries, are striving for superior innovation performance to cope with the challenges of contemporary educational environment. Drawing on the knowledge management capability model and knowledge-based view of firms, this study aims to determine the impact of knowledge management enablers, namely, top management knowledge value, knowledge-oriented culture and knowledge-based rewards, on innovation speed and quality and assessing the mediating role of knowledge sharing process.

Design/methodology/approach

Data are collected from 234 academics of higher education institutions in Pakistan and analyzed through the partial least squares structural equation modeling technique.

Findings

The results indicate that top management knowledge value and knowledge-based rewards have a positive effect on innovation speed and quality. Although knowledge-oriented culture also contributes to innovation quality, it does not influence the innovation speed. Moreover, the knowledge sharing process mediates the effect of all these knowledge management enablers on innovation speed and quality.

Practical implications

This study underscores the importance of three key knowledge management enablers in higher education institutions. The findings of this study suggest that signaling knowledge value from the top management, fostering knowledge-oriented culture and enacting a knowledge-based reward system are critical in facilitating knowledge sharing process and enhancing innovation speed and quality in higher education institutions.

Originality/value

This is among one of the earlier studies that investigates the influence of top management knowledge value, knowledge-oriented culture and knowledge-based rewards on innovation speed and quality, particularly in higher education institutions, and determines the mediating role of the knowledge sharing process.

Abstract

Purpose

Knowledge sharing in research communities has been considered indispensable to progress in science. The aim of this paper is to analyze the mechanisms restricting knowledge sharing in science. It considers three categories of academia–industry knowledge transfer and a range of individual and contextual variables as possible predictors of knowledge-sharing restrictions.

Design/methodology/approach

A unique empirical data sample was collected based on a survey among 212 life science researchers affiliated with universities and other non-profit research institutions. A rich descriptive analysis was followed by binominal regression analysis, including relevant checks for the robustness of the results.

Findings

Researchers in academia who actively collaborate with industry are more likely to omit relevant content from publications in co-authorship with other academic researchers; delay their co-authored publications, exclude relevant content during public presentations; and deny requests for access to their unpublished and published knowledge.

Practical implications

This study informs policymakers that different types of knowledge-sharing restrictions are predicted by different individual and contextual factors, which suggests that policies concerning academia–industry knowledge and technology transfer should be tailored to contextual specificities.

Originality/value

This study contributes new predictors of knowledge-sharing restrictions to the literature on academia–industry interactions, including outcome expectations, trust and sharing climate. This study augments the knowledge management literature by separately considering the roles of various academic knowledge-transfer activities in instigating different types of knowledge-sharing restrictions in scientific research.

Abstract

Purpose

The purpose of this paper is to investigate the mediator role that knowledge sharing plays between organisational culture, organisational structure, and technology infrastructure and process improvement in a knowledge management context in manufacturing enterprises operating in the food, beverage and textile industry.

Design/methodology/approach

An empirical study is conducted with a sample of 200 food, beverage and textile companies. Data are obtained by means of a survey questionnaire applied to general managers in each of the sample firms. The impact of the factors organisational culture, organisational structure and technology infrastructure on process improvement via knowledge sharing is assessed. Structural equation modelling and maximum likelihood estimation are applied to find the direction and strength of the relationships.

Findings

The main findings indicate the significant relationships between knowledge sharing and process improvement, between organisational culture and knowledge sharing, and between organisational structure and knowledge sharing. The relationship between technology infrastructure and knowledge sharing is found not to be significant.

Research limitations/implications

The findings of the present study are limited to the food, beverage and textile industry. Future research could incorporate data from other manufacturing sectors or service companies.

Practical implications

This study provides practical guidance for general managers who wish to implement process improvement programmes.

Originality/value

Several authors have noted that there are few research studies concerning the interaction between each phase of knowledge management and total quality management practices. This study is interested in knowledge sharing and its impact on process improvement in a knowledge management context.

Abstract

Purpose

Young people’s attachment to their smartphones is well-documented, with smartphones often described as prostheses. While prior studies typically assume a clear human/machine divide, this paper aims to build on posthuman perspectives, exploring intercorporeality, the blurring of human/technology boundaries, between emerging adults and their smartphones. The paper aims to discuss these issues.

Design/methodology/approach

Drawing on assemblage theory, this interpretive study uses smartphone diaries and friendship pair/small group discussions with 27 British emerging adults.

Findings

Participants in this study are characterized as homo prostheticus, living with and through their phones, treating them as extensions of their mind and part of their selves as they navigated between their online and offline, private and social lives. Homo prostheticus was part of a broader assemblage or amalgamation of human and non-human components. As these components interacted with each other, the assemblage could be strengthened or weakened by various technological, personal and social factors.

Research limitations/implications

These qualitative findings are based on a particular sample at a particular point in time, within a particular culture. Further research could explore intercorporeality in human–smartphone relationships among other groups, in other cultures.

Originality/value

Although other studies have used prosthetic metaphors, this paper contributes to understanding of smartphones as a prostheses in the lives of emerging adults, highlighting intercorporeality as a key feature of homo prostheticus. It also uses assemblage theory to contextualize homo prostheticus and explores factors strengthening or weakening the broader human–smartphone assemblage.
