Abstract

Purpose

Based on the theoretical predictions of media equation theory and the computers-are-social-actors (CASA) perspective, this study aims to examine the effects of performance error type (i.e. logical, semantic or syntactic), task type and personality presentation (i.e. dominant/submissive and/or friendly/unfriendly) on users’ level of trust in their personal digital assistant (PDA), Siri.

Design/methodology/approach

An experimental study of human–PDA interactions was performed with two types of tasks (social vs functional) randomly assigned to participants (N = 163). While interacting with Siri in 15 task inquiries, the participants recorded Siri’s answers for each inquiry and self-rated their trust in the PDA. The answers were coded and rated by the researchers for personality presentation and error type.

Findings

Logical errors were the most detrimental to user trust. Users’ trust of Siri was significantly higher after functional tasks compared to social tasks when the effects of general usage (e.g. proficiency, length and frequency of usage) were controlled for. The perception of a friendly personality from Siri had an opposite effect on social and functional tasks in the perceived reliability dimension of trust and increased intensity of the presented personality reduced perceived reliability in functional tasks.

Originality/value

The research findings contradict predictions from media equation theory and the CASA perspective while contributing to a theoretical refinement of machine errors and their impact on user trust.

Abstract

Purpose

Performing accurate numerical simulations of electrical drives, the precise knowledge of the local magnetic material properties is of utmost importance. Due to the various manufacturing steps, e.g. heat treatment or cutting techniques, the magnetic material properties can strongly vary locally, and the assumption of homogenized global material parameters is no longer feasible. This paper aims to present the general methodology and two different solution strategies for determining the local magnetic material properties using reference and simulation data.

Design/methodology/approach

The general methodology combines methods based on measurement, numerical simulation and solving an inverse problem. Therefore, a sensor-actuator system is used to characterize electrical steel sheets locally. Based on the measurement data and results from the finite element simulation, the inverse problem is solved with two different solution strategies. The first one is a quasi Newton method (QNM) using Broyden's update formula to approximate the Jacobian and the second is an adjoint method. For comparison of both methods regarding convergence and efficiency, an artificial example with a linear material model is considered.

Findings

The QNM and the adjoint method show similar convergence behavior for two different cutting-edge effects. Furthermore, considering a priori information improved the convergence rate. However, no impact on the stability and the remaining error is observed.

Originality/value

The presented methodology enables a fast and simple determination of the local magnetic material properties of electrical steel sheets without the need for a large number of samples or special preparation procedures.

Abstract

The role of caregivers and issues of parenting are controversial in research on disability. While appreciating the historical and political reasons to critique power relations in care systems and care relations, we argue that it is important to consider parents' and other caregivers' positions. A reconsideration provides insights into pervasive effects of ableism defining not only the individual child but parents and other relatives as well. We draw from extensive research on couples parenting a child with disability in Germany (Tröndle, 2022a). This study seeks to understand how parents of a child with disability cannot avoid understanding themselves as “special parents.” Through analyzing shared life stories of couples and individual biographies, the study reconstructs how identities evolve differently depending on their work-sharing arrangements. Based on our findings, the couples experience difficulties in maintaining dual employment arrangements. They become “unable” to step outside of the logic of welfare and health provision and structures of the labor market. Couples begin to explain their situation and the discrimination they experience by reflecting themselves as “special parents.” Heteronormative and ableist expectations hinder them in articulating resistance and gaining agency as allies of their children, facilitating positions of complicity. We argue that the approach suggested by this study – namely including the ambiguous situation of caregivers in Disability Studies – can encourage other researchers to consider othering and ableism of and by caregivers.

Abstract

In the big data era, image compression is of significant importance in today’s world. Importantly, compression of large sized images is required for everyday tasks; including electronic data communications and internet transactions. However, two important measures should be considered for any compression algorithm: the compression factor and the quality of the decompressed image. In this paper, we use Frei-Chen bases technique and the Modified Run Length Encoding (RLE) to compress images. The Frei-Chen bases technique is applied at the first stage in which the average subspace is applied to each 3 × 3 block. Those blocks with the highest energy are replaced by a single value that represents the average value of the pixels in the corresponding block. Even though Frei-Chen bases technique provides lossy compression, it maintains the main characteristics of the image. Additionally, the Frei-Chen bases technique enhances the compression factor, making it advantageous to use. In the second stage, RLE is applied to further increase the compression factor. The goal of using RLE is to enhance the compression factor without adding any distortion to the resultant decompressed image. Integrating RLE with Frei-Chen bases technique, as described in the proposed algorithm, ensures high quality decompressed images and high compression rate. The results of the proposed algorithms are shown to be comparable in quality and performance with other existing methods.

Abstract

Purpose

This study aimed to determine the factors affecting consumers’ perceptions and intention to purchase home meal kit services (HMK), a convenient home-cooked meal option, considering the moderating effects of monetary restriction, through the lens of the theory of planned behaviour (TPB).

Design/methodology/approach

This cross-sectional study used an online, self-administered survey to collect data from 374 US adults. Results were tested for variable associations via multiple linear regression and moderation analyses.

Findings

HMK adoption intention was positively associated with attitude and subjective norms but negatively associated with perceived behavioural control. Consumers’ HMK attitude demonstrated a significant positive relationship with food safety concerns and perceived time constraints. Income and financial constraints were significant moderators of the associations between TPB determinants and HMK intention. The findings emphasised the possibility of using HMK as a foodservice option for time-challenged consumers with food safety concerns.

Originality/value

This study addressed the limited research on HMK, a competitive meal option that foodservice businesses could implement to boost revenue. The study establishes the contribution in understanding the motivators and barriers that potentially affect consumers’ HMK behaviour through the lens of TPB. The results expand the scope of the TPB application in food-related research, providing a deeper understanding of antecedents and other factors on consumers’ HMK behavioural attitudes. Understanding this information will enable practitioners to develop strategies that meet consumers’ concerns when embracing this service to promote HMK.

Abstract

Artifacts are rarely used today to visualize thoughts, insights, and ideas in strategy work. Rather, textual and verbal communication dominates. This is despite artifacts and visual representations holding many advantages as tools to create and make sense of strategy in teamwork. To advance our understanding of the benefits of visual aids in strategy work, I synthesize insights from cognitive psychology, neuroscience, and management research. My analysis exposes distinct neurocognitive advantages concerning attention, emotion, learning, memory, intuition, and creativity from visual sense-building. These advantages increase when sense-building activities are playful and storytelling is used.

Abstract

Purpose

The purpose of this study is to extend the research on fashion renting (FR) by investigating how personal and social motives (i.e. “subjective norms”, “perceived behavioural control”, “sustainable orientation” and “FR benefits”) affect consumers’ attitudes and intentions towards it. In addition, personality traits are investigated as potential antecedents of FR, resulting in the proposal of an overall framework that combines the theory of planned behaviour with the trait theory approach.

Design/methodology/approach

Data were collected in Italy from a sample of 694 consumers, mainly females (88%), with an average age of 28.8 years and coming from all over the country. The collected data were then processed via structural equation modelling.

Findings

The results indicated that intention towards FR is influenced by attitude, which, in turn, is affected by social norms, perceived behavioural control, sustainable orientation and FR benefits. Furthermore, only fashion leadership acts as a direct antecedent of FR attitude, while the need for uniqueness and materialism plays critical roles as predictors of personal and social motives. Subjective norms and perceived behavioural control also serve as mediators of the significant relationships between personality traits and attitudes towards FR.

Practical implications

The study provides useful implications for fashion rental companies in attracting consumers and offers a foundation for further research on transforming traditional consumption into a more sustainable one.

Originality/value

The study presents new knowledge on the rental phenomenon in the fashion sector by responding to the call to deepen the analysis of factors that influence consumers’ adoption of FR from the perspectives of personal and social motives and personality traits.

Abstract

Purpose

The type of social capital among families involved in business, or family social capital, has both positive and negative effects on family firms. This paper aims to investigate the mediating role of social relationships of family business members between socioemotional wealth (SEW) and firms' entrepreneurial orientation.

Design/methodology/approach

The authors applied a survey conducted in the four main cities in Mexico. The sample consisted of 360 small and medium enterprise (SMEs). This study's research framework and hypothesis were tested using regression analysis and the structural equation modeling technique.

Findings

This study finds that not only does SEW strongly influence the entrepreneurial orientation of family firms, but this influence is also mediated by the capability of such families to develop their social capital.

Research limitations/implications

The results show the perspective of one person in the company. Though it is the person with the highest rank and presumably the person who thoroughly knows the company, there is always a possibility of bias, which may inflate the results presented in this paper.

Practical implications

Based on this study's results, family firms should continuously improve their entrepreneurial abilities to achieve sustainable competitive advantage. In addition, their unique family-related characteristics further enhance these strategic approaches' positive effects on relational capital development.

Originality/value

This work contributes to the academic literature on entrepreneurship and social capital. As a mediator between SEW and entrepreneurial orientation, family relational capital has been under-researched. The results of this study reveal significant implications for networking management and relational capital strategies for SMEs.

Abstract

Purpose

The aim of this study is to test for a moderating role of employee participation in volunteering in links between employees' relationships with peers and supervisors, work meaningfulness (WM) and affective commitment (AC).

Design/methodology/approach

The study is based on a survey conducted on a sample of 711 employees, both those involved and those non-involved in corporate volunteering (CV).

Findings

The results suggest that employee participation in CV strengthens the effects that employees' perceptions of positive relationships with peers and perceived supervisor support (PSS) have on employees' AC. Contrary to expectations, although participation in CV strengthens employees' sense of WM, it does not affect its links with other phenomena analyzed in this study.

Originality/value

CV is a fast-growing practice in corporate social responsibility. The reasons companies implement CV include the benefits they gain from it, such as positive effects on employee attitudes and behaviors. The paper contributes to the understanding of CV effects on employee attitudes and behaviors and builds a better business case for this CSR practice.
