Abstract

This paper describes the typical specifications and features of a novel low‐cost and high‐performance universal transducer interface (UTI). The easy‐to‐use interface enables fast prototyping of systems with capacitive sensors, platinum resistors, thermistors, resistive bridges and potentiometers. It is shown that a high accuracy and reliability can be obtained by applying a combination of advanced techniques, such as, auto‐calibration, advanced chopping and dynamic element matching. Examples of smart sensor systems, using the UTI and the popular microcontrollers, Intel 87C51FX and PIC16C73, have been presented.

Abstract

Purpose

The aim of this paper is gaining a deeper understanding of potential negative effects of (smart)phone use at work. The authors do so by exploring mediating mechanisms and boundary conditions between leader phubbing, leaders snubbing their followers by glancing at their phones during an interaction; and follower (1) work engagement and (2) performance.

Design/methodology/approach

The authors conducted a survey-based time-lagged, multi-source and team-based study of leaders (N = 93) and their followers (N = 454).

Findings

Results of this paper showed that leader phubbing negatively relates to follower (1) work engagement and (2) performance through less perceived leader support. Contradictory to the hypothesis, the relationship between leader phubbing and perceived leader support was negative for male leaders only.

Originality/value

The authors contribute to existing research by (1) adding perceived support as an important mediator between leader phubbing and work engagement/performance, (2) exploring the effects of leader gender and (3) adding information on the cultural robustness of the leader phubbing phenomenon by testing it outside the Western work context.

Abstract

Purpose

The purpose of this paper is to examine business growth and explore the “growth mode” among 24 women entrepreneurs participating in a Nordic research, development and networking programme.

Design/methodology/approach

A longitudinal design made it possible to follow entrepreneurial growth as an unfolding and emerging research process with a methodology inductive in nature and driven by empirical findings. The analysis is structured following established procedures for inductive, theory-building research, using guidelines for constant comparison techniques and working recursively between the data and the emerging theory.

Findings

Two processes were found important to understand the women entrepreneurs’ growth mode. The first is interpreted as intentionally driven and relates to the women’s achievement of expanding their knowledge reservoir; the other is non-intentionally driven and a result of uncontrolled network responses. The latter unfolded as a movement towards a preferable macro-actor status for some of the entrepreneurs.

Practical implications

The study calls attention to relevant knowledge preferable to entrepreneurs who face challenges when trying to grow their businesses. The political implications of this study relate to the importance of awareness among governmental organizations and municipal business advisers regarding the effects of entrepreneurial networking.

Originality/value

This study provides an empirically rigorous insight into the processes of entrepreneurial growth. The findings led the authors to develop a conceptual model for business growth, which contributes to the recent stream of literature on how new businesses are growing.

– The purpose of this paper is to combine social identity and social exchange theories into a model explaining turnover intentions.

Abstract

Purpose

The purpose of this paper is to combine social identity and social exchange theories into a model explaining turnover intentions.

Design/methodology/approach

Questionnaires measuring the constructs of organizational identification, perceived organizational support, emotional exhaustion, and turnover intentions were completed by 195 employees.

Findings

Results supported our hypotheses: social identification increased the perception of organizational support which in turn reduced emotional exhaustion which was finally related to turnover intentions. Furthermore, social identification moderated the relation between organizational support and turnover intentions.

Research limitations/implications

The study design was cross-sectional and data were collected using self-report with no assessment of objective data.

Practical implications

To reduce turnover, managers should focus on both support and employees’ identification with teams and organizations.

Originality/value

This study combines two theoretical perspectives into an integrative framework and simultaneous moderated-mediation was used to test the model.

Abstract

Purpose

Entomology is a useful tool when applied to engineering challenges that have been solved in nature. Especially when these special abilities of olfactory sensation, vision, auditory perception, fly, jump, navigation, chemical synthesis, exquisite structure and others were connected with mechanization, informationization and intelligentization of modern science and technology, and produced innumerable classical bionic products. The paper aims to discuss these issues.

Design/methodology/approach

All kinds of special abilities of insects and application status have been described and discussed in order to summarize the advanced research examples and supply bibliographic reference to the latters. Future perspectives and challenges in the use of insect bionics were also given.

Findings

In the period of life sciences and information sciences, insect bionics not only promoted the development of modern science and technology on the sides of mechanics, molecule, energy, information and control greatly but also provided new ideas and technologies for the crisis of science and technology, food, environment and ecosystem.

Originality/value

It may provide strategies to solve the problems and be a source of good ideas for researchers.

Abstract

Purpose

The study aims to compare survey recruitment rates between Facebook, Twitter and Qualtrics and to assess the impact of recruitment method on estimates of energy content, food safety, carbon footprint and animal welfare across 29 foods.

Design/methodology/approach

Two versions of an online survey were developed on the citizen science platform, Zooniverse. The surveys explored citizen estimations of energy density (kcal) or carbon footprint (Co2) and food safety or animal welfare of 29 commonly eaten foods. Survey recruitment was conducted via paid promotions on Twitter and Facebook and via paid respondent invites on Qualtrics. The study included approximately 500 participants (Facebook, N˜11 (ratings 358), Twitter, N˜85 (ratings 2,184), Qualtrics, N = 398 (ratings 11,910)). Kruskal–Wallis and Chi-square analyses compared citizen estimations with validated values and assessed the impact of the variables on estimations.

Findings

Citizens were unable to accurately estimate carbon footprint and energy content, with most citizens overestimating values. Citizen estimates were most accurate for meat products. Qualtrics was the most successful recruitment method for the online survey. Citizen estimates between platforms were significantly different, suggesting that Facebook and Twitter may not be suitable recruitment methods for citizen online surveys.

Practical implications

Qualtrics was the favourable platform for survey recruitment. However, estimates across all recruitment platforms were poor. As paid recruitment methods such as Qualtrics are costly, the authors recommend continued examination of the social media environment to develop appropriate, affordable and timely online recruitment strategies for citizen science.

Originality/value

The findings indicate that citizens are unable to accurately estimate the carbon footprint and energy content of foods suggesting a focus on consumer education is needed to enable consumers to move towards more sustainable and healthy diets. Essential if we are to meet the 2030 Sustainable Development Goals of zero hunger, good health and wellbeing and responsible consumption and production. The study highlights the utility of Zooniverse for assessing citizen estimates of carbon footprint, energy content, animal welfare and safety of foods.

Abstract

Purpose

The purpose of this paper is to study how operations strategy (OS) innovation occurs in a project-centred production and organisation.

Design/methodology/approach

A longitudinal case study encompassing the processes at the headquarters of the company and in two projects using lean.

Findings

The operation strategy development commences at a middle level in the organisation, is underpinned and embedded in production projects and only after several years becomes embedded in the corporate operation strategy. Projects use lean principles in a differentiated manner.

Research limitations/implications

A qualitative case study provides insight into only a single occasion of change in OS. More case studies would probably reveal several paths of OS development. OS development need to be handled as emergent, political and with contributions from several managers and management levels, bridging the vertical divides between projects and headquarter.

Practical implications

A conscious and systematic vertical integration and interaction is crucial in project-based companies doing operation strategy development, something critically difficult at building contractors.

Originality/value

The present study contributes to the small body of studies of OS development processes, by providing insight in how project-based companies renew their operation strategy.
