Electric sliding wear performance optimization of rigid contact wire/strip pairs under DC passage
Authors: Mei Guiming 
Published: April 2022

Purpose
This paper aims to study the electric sliding wear performance of a rigid overhead line/contact strips and to find an optimal overhead line/contact strip pair to minimize the wear of the contact strip under direct current (DC) passage.

Design/methodology/approach
The tribological characteristics of an overhead line against four contact strips with DC were experimentally investigated using a block-on-disc tester. The wear and temperature of the contact strips were collected and analysed. The severe wear mechanism of the contact strips was discussed.

Findings
Using Taguchi’s method, DC was found to be the most important factor affecting the wear and temperature of current collectors, the normal force being the second and the sliding velocity the weakest. The abnormal wear of current collectors was attributed to arc ablation and poor thermal stability of collectors. The wear performances of current collectors could be optimized by matching different Cu-impregnated carbon strips with the Cu–Ag wire and the wear of current collectors could be reduced by selecting the appropriate normal force, DC and sliding velocity.

Originality/value
Among all test parameters such as the DC, normal force, sliding speed and collector type, DC was identified as the most important factor affecting the wear and temperature of contact strips for the first time. The arc ablation and thermal stability of collectors were considered to be two main factors affecting the wear of the collectors.
When cyberaggression is personal: gender differences in threats and betrayals of partners and friends
Authors: Eriksson Li , McGee Tara Renae , Rosse Viktoria , Bond Christine , Horstman Nicole 
Published: April 2022

Purpose
New ways of perpetrating relational aggression have been facilitated by the increased availability and adoption of technology for communication, resulting in growing cyberaggression rates over the past few decades. Few studies have examined whether perpetrators of cyberaggression are more likely to target friends or romantic partners (or both) and whether this differs across the gender of the perpetrator. This is the key focus of the current study.

Design/methodology/approach
Participants completed an online survey which assessed three types of cyberaggression (threatened to share secrets, shared secrets and posted embarrassing pictures) against friends and then also against romantic partners. The sample included 678 undergraduate university students who were in a romantic relationship at the time of the survey (72.6% female and 27.4% male, age range 18–50 years, average 21.7 and SD = 4.5).

Findings
The results of this study showed that a significantly higher proportion of males than females perpetrated cyberaggression against friends and romantic partners. In addition, a significantly higher proportion of males engaged in “general” cyberaggression (targeting both friends and romantic partners), whilst a higher proportion of females engaged in “selective” cyberaggression (targeting either friends or romantic partners).

Originality/value
Collectively, this study tells us that whilst there has been wide examination of cyberaggression more broadly, very few studies explore who perpetrators target (i.e. the victim–offender relationship), especially across gender of the perpetrator. The current study is original in that it asks perpetrators to report who they target and then examines gender differences in perpetration rates across victim–offender relationships.
Cacao value chains and credence attributes: lessons from Ecuador
Authors: Villacis Alexis , Alwang Jeffrey , Barrera Victor 
Published: April 2022

PurposeMotivated by transformations in global food systems and increasing demand for multidimensional credence attributes, the authors analyze cacao value chains in Ecuador – the main producer of fine and flavor cacao worldwide. The authors identify opportunities and discuss how private and public sector initiatives can help meet emerging challenges.Design/methodology/approachPrimary information was collected through interviews of actors in the Ecuadorian industry during spring/summer 2020, including cacao producer associations, exporter associations, chocolate processing firms, public institutions and local universities. Two focus groups were also conducted with producers from associations in the Ecuadorian Amazon.FindingsFindings suggest new opportunities for cacao producers and chocolate processors have emerged from the global market transformation. To exploit these, firms need to personalize and differentiate their products, for example, by using quality certifications such as organic and fair trade. Market developments, such as European cadmium regulations and the necessity of worldwide traceability systems, are driving exporters to enhance Ecuador’s cacao value chains. The sector still requires coordination to reap the benefits associated with demands for credence attributes.Originality/valueFindings are supported by two case studies. The first focuses on how associativity can help those producing high-quality beans to differentiate themselves in modern agri-food markets. The second describes the success of a local chocolate firm and its links with local farmers.
Credence attributes and opportunities: a cautionary tale of yerba mate in Paraguay
Authors: Alwang Jeffrey , Villacis Alexis , Barrera Victor 
Published: April 2022

PurposeThis study explores the determinants of growth of credence-based exports of yerba mate from Paraguay, potential for increased export growth, and the fragility of the credence-based export model. Much of the growth in value of yerba mate exports from Paraguay is due to positioning of the good within the universe of products where consumption is driven by perceptions of sustainable production and health benefits to consumers. Credence claims for yerba mate—benefits to indigenous producing communities, environmental sustainability under certain production processes, healthful alternatives to energy drinks—are now widely known, but the growth of this awareness came via a new entrepreneurial strategy of a single firm.Design/methodology/approachPrimary information was collected through interviews of actors in the Paraguayan yerba mate value chain during spring/summer 2020. These included representatives from three exporting companies, processors, public institutions and indigenous producers.FindingsThe Paraguayan yerba mate export boom was stimulated through the careful cultivation of an image of healthful consumption and sustainable production processes. The cost of this cultivation was borne mainly by a single firm. Findings suggest that future marketing efforts will need to reinforce credence claims, highlighting the benefits to indigenous producers.Research limitations/implicationsThis case study explores the determinants of growth of credence-based exports of yerba mate from Paraguay, potential for increased growth, and the fragility of the credence-based model.Originality/valueFindings are supported by field interviews with value chain participants and detailed analysis of extant data. The paper is the first to discuss the fragility of relying on credence attributes for long-term demand growth.
Migration contexts in shaping community ethnic resources: a Forms of Capital approach on ethnic migrant entrepreneurs in Malaysia
Authors: Abd Hamid Hamizah , Everett André M. 
Published: April 2022

Purpose
This paper aims to refine the concept of community/ethnic resources for migrant communities by focusing on the way ethnic migrant entrepreneurs (EMEs) use co-ethnic-based (CEB) resources in their entrepreneurial activities, taking into account their migration contexts. Migrants are usually considered as disadvantaged individuals given their restricted opportunities in the labor market and in the business arena; thus, they rely on ethnic resources for survival in the host country.

Design/methodology/approach
Through Bourdieu’s (1986) forms of capital model, the authors compare the experiences of EMEs from three migrant communities in Malaysia (specifically, the Indonesian, Pakistani and South Korean communities) with regard to their ethnic resources. The authors used a qualitative approach in analyzing our data, which includes interview narratives with 41 individuals consisting of EMEs, community leaders, embassy representatives and trade experts.

Findings
This study’s findings indicate that migration contexts influence the differences in the way ethnic resources are used by EMEs. The findings are synthesized into a framework of ethnic resources within the context of ethnic migrant entrepreneurship.

Research limitations/implications
Adopting a qualitative approach was useful in studying the subject, but the findings are still limited within the context of the study. As such, future research is encouraged to test the proposed framework and examine the underexplored aspects of migration in influencing the utilization of ethnic resources for entrepreneurial migrant communities.

Practical implications
A practical implication of this paper lies in the illustration of migrants’ usage of alternative routes for resources through co-ethnic networks, which is useful for policymakers and businesses focusing on migration and trade.

Originality/value
This framework contributes to the discourse of ethnic migrant entrepreneurship through further clarifying aspects shaping the utilization of community ethnic resources.
Algorithmic pricing in hospitality and tourism: call for research on ethics, consumer backlash and CSR
Authors: van der Rest Jean-Pierre , Sears Alan M. , Kuokkanen Henri , Heidary Kimia 
Published: April 2022

PurposeThis viewpoint paper calls for research on the social impact that comes with implementing algorithmic pricing in hospitality and tourism, in particular online price discrimination. It seeks to broaden the literature on consumer backlash and corporate social responsibility (CSR) to include algorithmic pricing.Design/methodology/approachAs algorithmic pricing will become increasingly important in hospitality and tourism, the authors argue that scholarly attention should be directed to two topics.FindingsFirst, there is a need for research on how algorithmic pricing triggers consumer backlash and online firestorms, and how these can be detected, prevented, and mitigated. Second, the authors need to increase our understanding of how deception, misconduct, dishonesty, and injustice in algorithmic pricing impact CSR performance, especially when differential pricing is enticed by deceptive yet legal algorithmic applications of indirect behavioral “self-selection” mechanisms.Social implicationsAlgorithmic price discrimination has been criticized for its potential to harm consumers, and doubt is cast upon the current ability of legal frameworks to set minimum standards of behavior.Originality/valueAlgorithmic pricing includes a variety of computerized pricing applications aimed at increasing revenue and minimizing opportunity costs. With early use by airlines decades ago its diffusion has gradually extended to other sectors including hospitality and tourism. While algorithms are expected to increasingly impact pricing decisions, little research can be found on the topic, with the exception of a vigorous debate in the policy literature on its ethical implications and regulatory needs.
Communicated ethical identity disclosure (CEID) of Islamic banks under the AAOIFI and IFRS accounting regimes: a global evidence
Authors: Gadhoum Mohamed Anouar , Muhamad Sori Zulkarnain Bin , Ramadilli Shamsher , Mahomed Ziyaad 
Published: April 2022

Purpose
This paper aims to assess the ethical disclosure of Islamic banks (IBs) under different accounting regimes and to ascertain whether the adoption of an Islamic accounting standards (Auditing Organization for Islamic Financial Institutions [AAOIFI]) promotes the practice of ethical disclosure.

Design/methodology/approach
An ethical identity disclosure index was developed to serve as a benchmark to assess the level of the communicated ethical identity disclosure (CEID) of 47 IBs over 18 countries using annual reports.

Findings
The findings suggest that, overall, there is poor ethical disclosure practices and even banks that had some initiatives towards disclosures had no proper reference to benchmark for effective implementation of ethical reporting standards and had no plans for ethical and socially responsible schemes. There was no evidence to suggest that IBs that adapted the religious-based accounting regime (AAOIFI) had better levels of ethical disclosure.

Research limitations/implications
Though poor practices of CEID are expected to increase reputational risks and the likelihood of loss of religious conscious customers and investors’ confidence and therefore market share and performance in the long-term, the current practice does not concur with this expectation. Furthermore, since there is no evidence to support the notion that the adoption of AAOIFI standards would support greater initiatives towards level of ethical identity disclosures, a mandatory requirement for effective disclosure through enforcement of AAOIFI’s financial reporting standards, specifically with regard to ethics and social and environmental commitment is needed.

Practical implications
In addition to introducing commonly accepted regulatory and supervisory guidelines and best practices that cater for the specificities of Islamic banking could significantly improve the level of CEID of IBs. In addition, the standardization of ethical (non-financial) reporting practices of IBs through guidelines and key performance indicators will facilitate CEID practices of IBs.

Originality/value
This paper contends that for Islamic bankers, ethics is an entrenched part of the business practice and should mitigate unethical behaviour, more so with the additional filter of Sharīʿah supervisory boards. Even if there are such practices due to ineffectiveness of Sharīʿah committees, management pressure to meet performance expectations and competitive pressures from peers in the conventional banking sector, it will not be in the interest of the banks to report them.
A systematic literature review of the effects of coworking spaces on the socio-cultural and economic conditions in peripheral and rural areas
Authors: Vogl Thomas , Akhavan Mina 
Published: April 2022

PurposeThe literature on coworking spaces (CSs) is growing fast; notably, this topic has attracted a wide range of contributions from various disciplines during the past years. Although CSs first appeared in major cities, small towns and rural areas are also becoming attractive. To date, no literature review has systematically studied the effects of such collaborative-flexible new working spaces proliferating in non-urban areas. Therefore, this paper aims to present a systematic literature review about the effects of coworking spaces located in peripheral and rural areas.Design/methodology/approachThe methodological approach is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, also known as PRISMA. Following the PRISMA checklist items, this study provides different aspects and identifies indicators from various cross-studies published in 10 years (2011–2021).FindingsResults show that, in the past decade, Europe has recorded the highest number of publications on the topic of coworking spaces (CSs); the main research focus was on spatial planning. CSs foster communities of specialized and high-skilled workers, attract businesses and venture capitalists and may accelerate urban revitalisation processes. The regeneration of spaces can positively affect the value of commercial properties in the vicinity and attract developers. Moreover, by establishing communities and networks beyond the working life, coworking was found to reduce depopulation and even foster the influx of non-urban areas.Practical implicationsThe findings of this study can be transferred to policymakers to be considered in designing tailored policies in non-urban areas and also places-that-don't matter.Originality/valueBy date, this study is the first attempt to conduct a systematic review of the literature on the effects of coworking spaces in peripheral and rural areas. This is important since this typology of flexible-collaborative working space is gaining public attention, especially during the pandemic and the development of such spaces in non-urban areas.

Authors: Divya D. , Marath Bhasi , Santosh Kumar M.B. 
Published: April 2022

PurposeThis study aims to bring awareness to the developing of fault detection systems using the data collected from sensor devices/physical devices of various systems for predictive maintenance. Opportunities and challenges in developing anomaly detection algorithms for predictive maintenance and unexplored areas in this context are also discussed.Design/methodology/approachFor conducting a systematic review on the state-of-the-art algorithms in fault detection for predictive maintenance, review papers from the years 2017–2021 available in the Scopus database were selected. A total of 93 papers were chosen. They are classified under electrical and electronics, civil and constructions, automobile, production and mechanical. In addition to this, the paper provides a detailed discussion of various fault-detection algorithms that can be categorised under supervised, semi-supervised, unsupervised learning and traditional statistical method along with an analysis of various forms of anomalies prevalent across different sectors of industry.FindingsBased on the literature reviewed, seven propositions with a focus on the following areas are presented: need for a uniform framework while scaling the number of sensors; the need for identification of erroneous parameters; why there is a need for new algorithms based on unsupervised and semi-supervised learning; the importance of ensemble learning and data fusion algorithms; the necessity of automatic fault diagnostic systems; concerns about multiple fault detection; and cost-effective fault detection. These propositions shed light on the unsolved issues of predictive maintenance using fault detection algorithms. A novel architecture based on the methodologies and propositions gives more clarity for the reader to further explore in this area.Originality/valuePapers for this study were selected from the Scopus database for predictive maintenance in the field of fault detection. Review papers published in this area deal only with methods used to detect anomalies, whereas this paper attempts to establish a link between different industrial domains and the methods used in each industry that uses fault detection for predictive maintenance.
Using personalization for cause-related marketing beyond compassion fade on social media
Authors: Kim Jihye , Kim Minseong 
Published: April 2022

PurposeIn light of the increasing occurrences of social issues and natural disasters, the number of people who need financial assistance is also growing. Using the compassion fade framework, marketing scholars have focused on the impact of the number of victims in need of monetary donations. Situated in the cause-related marketing context, the purpose of this study is to test whether personalization and perceived social visibility moderate the influence of compassion on social engagement intention to participate in a company’s charity.Design/methodology/approachThis study conducted an online experiment with a 2 (number of children in need: single vs group) x 2 (personalization: personalized vs general) between subjects’ design and measured perceived social visibility as a numeric variable divided into three groups. Two-way analysis of covariance (ANCOVA), a simple moderation analysis, and a moderated mediation analysis using the PROCESS macro were conducted to test the hypotheses.FindingsCompassion fade occurred in general advertisements whereas the opposite tendency occurred in personalized advertisements. The positive effect of compassion on social engagement intention was stronger at a high level of perceived social visibility; the effect was significant but weak in the low perceived social visibility condition. The indirect effects from the number of children to social engagement intention via compassion were significant in the personalized ads with medium/high social visibility conditions and general ads with medium/high social visibility conditions; the indirect effects were insignificant in the personalized ads with low social visibility and general ads with low social visibility conditions.Practical implicationsThe findings of this study should help companies develop and implement effective cause-related marketing strategies via social media, providing consumers with an opportunity to show others how they support social and environmental issues.Originality/valueThis study increases the understanding of the influence of the number of children in need on social media posts incorporating cause-related marketing and emphasizes the interaction effects of compassion, personalization and perceived social visibility.
