User recommendation in online health communities using adapted matrix factorization
Authors: Yang Hangzhou , Gao Huiying 
Published: August 2021

PurposeOnline health communities (OHCs) are platforms that help health consumers to communicate with each other and obtain social support for better healthcare outcomes. However, it is usually difficult for community members to efficiently find appropriate peers for social support exchange due to the tremendous volume of users and their generated content. Most of the existing user recommendation systems fail to effectively utilize the rich social information in social media, which can lead to unsatisfactory recommendation performance. The purpose of this study is to propose a novel user recommendation method for OHCs to fill this research gap.Design/methodology/approachThis study proposed a user recommendation method that utilized the adapted matrix factorization (MF) model. The implicit user behavior networks and the user influence relationship (UIR) network were constructed using the various social information found in OHCs, including user-generated content (UGC), user profiles and user interaction records. An experiment was conducted to evaluate the effectiveness of the proposed approach based on a dataset collected from a famous online health community.FindingsThe experimental results demonstrated that the proposed method outperformed all baseline models in user recommendation using the collected dataset. The incorporation of social information from OHCs can significantly improve the performance of the proposed recommender system.Practical implicationsThis study can help users build valuable social connections efficiently, enhance communication among community members, and potentially contribute to the sustainable prosperity of OHCs.Originality/valueThis study introduces the construction of the UIR network in OHCs by integrating various social information. The conventional MF model is adapted by integrating the constructed UIR network for user recommendation.
Acceptance of wearable fitness devices in developing countries: exploring the country and gender-specific differences
Authors: Pandey Shweta , Chawla Deepak , Puri Sandeep , Jeong Luz Suplico 
Published: August 2021

Purpose
Notwithstanding the novelty and importance of wearable fitness devices, few studies have focussed on comparing the drivers of adoption and usage of wearable fitness in the context of developing countries. This study aims to explore factors that drive overall acceptance of wearable fitness devices in developing countries (India and the Philippines) and whether the impact of these factors on the intention to adopt (INT) differs by country and gender.

Design/methodology/approach
The study extends the existing body of knowledge by developing a model that integrates the impact of various perceived benefits (health, autonomy, social, hedonic, symbolic), health self-efficacy (HEALTHSE) and individual characteristics (technological innovativeness [TI]) on the INT wearable fitness devices and the moderating impact of country and gender. The analysis was carried out using partial least square and data of 343 respondents.

Findings
This study finds that the INT wearable fitness devices by consumers in developing countries are positively impacted by hedonic, health and autonomy, HEALTHSE and TI. Symbolic and social factors do not have any significant impact on the overall INT wearable fitness devices. However, there are country and gender-specific differences that are consequential to the development of marketing strategies.

Research limitations/implications
The framework and results are specific to the two countries and limited by convenience sampling. Future research can focus on replication across different countries and extend the model with additional contextual factors such as perceived risks.

Originality/value
To the best knowledge of the authors, this is one of the few studies to examine and compare the drivers of adoption of wearable fitness devices in lesser researched developing countries. Also, it is one of the few studies to compare the moderating impact of country and gender in the context of the INT wearable devices. The study provides a theoretical and methodological foundation for future research, as well as practical implications for global companies developing and promoting wearable fitness devices.

Authors: Suriani Suriani , Abd. Majid M. Shabri , Masbar Raja , A. Wahid Nazaruddin , Ismail Abdul Ghafar 
Published: August 2021

Purpose
The purpose of this study is to empirically analyze the role of sukuk in the monetary policy transmission mechanism through the asset price and exchange rate channels in the Indonesian economy.

Design/methodology/approach
Using the monthly data from January 2003 to November 2017, this study uses a multivariate vector error correction model causality framework. To examine the role of sukuk in the monetary policy transmission mechanism through the asset price channel, this study uses the variables of consumption, inflation, interest rates, economic growth and the composite stock price index. Meanwhile, to examine the role of sukuk in the monetary policy transmission mechanism through the exchange rate channel, this study used variables of inflation, interest rates, economic growth, foreign investment and exchange rate.

Findings
This study documented that sukuk has no causal relationship with inflation through asset price and exchange rate channels. Nevertheless, sukuk has a bidirectional causal relationship with economic growth through asset price and exchange rate channels. Sukuk is also documented to have a causal relationship with monetary policy variables of interest rate and stock prices through asset price and exchange rate channels. Finally, a unidirectional causality is recorded running from the exchange rate to sukuk in the exchange rate channel.

Research limitations/implications
The finding of independence of the sukuk market from interest rates provides evidence that the trading of the sukuk in Indonesia has been in harmony with the Islamic tenets.

Practical implications
The relevant Indonesian authorities need to enhance both domestic and global sukuk markets as part of efforts to promote the sustainability of Islamic capital market development in Indonesia.

Originality/value
To the best of the authors’ knowledge, this study is among the first attempts to empirically investigate the role of sukuk in monetary policy transmission through asset price and exchange rate channels in the context of the Indonesian economy.
Supporting minority groups in schools – reflections on training education mental health practitioners
Authors: Woodley Helen 
Published: August 2021

Purpose
This study aims to reflect upon the first wave of training of Education Mental Health Practitioners (EMHPs), a new National Health Service role to provide support for Children and Young People (CYP) with low and moderate mental health needs in education settings in England. The study specifically focusses on the training for EMHPs in relation to their support for CYP who identify themselves as Black, Asian or Minority Ethnic (BAME), refugees or from the traveller community.

Design/methodology/approach
A brief review of the policy and literature on the role and remit of EMHPs was undertaken, including an exploration of the current status of BAME, refugee and traveller community CYP in schools in England. The review was then related to the specific experience of the author within the context of teaching EMHP trainees in a higher educational setting and evaluated as developing outcomes in low-intensity school-based practice.

Findings
There are benefits for trainee EMHPs to have an understanding of the minority groups of CYP attending schools in the area their Mental Health Support Team (MHST) covers. There are benefits for the MHST to form relationships with minority groups at an early stage in the MHST formation. Adapting the EMHP curriculum at a local level to include specific training on the needs of minority groups supports the development of relationships between schools and the communities they engage with locally. Ongoing training should be provided by services focussing on the specific needs of minority groups in their MHST area.

Originality/value
Involving minority groups in education in the formation of MHST and the training of EMHPs may improve outcomes in developing therapeutic relationships with CYP. Developing engagement practices in MHSTs with higher education providers, begins the process early in the experience of EMHP trainees, providing a safe environment in which to develop engagement skills.
Moral communication and legal uncertainty in small and medium enterprises
Authors: Winczorek Jan 
Published: August 2021

PurposeThe links between moral communication and legal communication have long been studied in sociology of law. Little has yet been said about moral communication invoking when communication in the legal system is impossible, ineffective or uncertain. The paper fills this gap to demonstrate that systems theory-based sociology of law can effectively recognise the role of moral communication in such situations.Design/methodology/approachThe paper presents an empirical study of moral communication in small and medium-sized enterprises (SMEs). It focused on situations when SMEs' interactions with function systems, particularly the legal system, result in irremovable legal uncertainty. The data depict strategies of managing such uncertainty and were obtained in a paths-to-justice survey of 7,292 owners and managers of SMEs and 101 in-depth interviews. The findings are interpreted using the author's concept of “uncertainty translation”, rooted in Luhmann's systems theory. It suggests that business organisations such as SMEs deal with the ubiquitous uncertainty in their operations by translating it into a convenient type.FindingsThe study distinguishes between formative and absorbing moral communication and finds that both types play a role in steering the uncertainty translation mechanism in SMEs. Six scenarios of invoking moral communication are identified in SMEs dealing with legal uncertainty. In such scenarios, moral communication facilitates the translation of business uncertainty “away from law”. Under some circumstances, this, in turn, leads to latent systematic results, reflexively affecting the legal system, the economic system and the SMEs.Research limitations/implicationsIn its core argument, the study is based on qualitative material. While it identifies empirical scenarios of invoking moral communication, it does not report the prevalence of these scenarios due to methodological limitations.Originality/valueThe study results pose questions related to the staple theoretical issue in post-Luhmannian social systems theory: functional differentiation. If moral communication–a type of communication not linked to any social system–can produce far-reaching, systematic results that affect function systems, then the functional differentiation thesis should be less pronounced than Luhmann typically stressed. This said, the paper argues that the contradiction between the findings and Luhmannian theory of morality is only apparent and may be reconciled.
Heat treatment effect on fatigue behavior of 3D-printed maraging steels
Authors: Tezel Tugce , Kovan Volkan 
Published: August 2021

Purpose
This study aims to reveal that fatigue life is improved using heat treatment in the rotational bending fatigue test, which determines the fatigue behavior closest to service conditions.

Design/methodology/approach
It is essential to know the mechanical behavior of the parts produced by additive manufacturing under service conditions. In general, axial stress and plane bending tests are used by many researchers because they are practical: the service conditions cannot be sufficiently stimulated. For this reason, the rotating bending fatigue test, which represents the conditions closest to the service conditions of a load-bearing machine element, was chosen for the study. In this study, the rotational bending fatigue behavior of X3NiCoMoTi18-9–5 (MS1) maraging steel specimens produced by the selective laser melting (SLM) technique was experimentally investigated under various heat treatments conditions.

Findings
As a result of the study, MS1 produced by additive manufacturing is a material suitable for heat treatment that has enabled the heat treatment to affect fatigue strength positively. Cracks generally initiate from the outer surface of the sample. Fabrication defects have been determined to cause all cracks on the sample surface or regions close to the surface.

Research limitations/implications
While producing the test sample, printing was vertical to the print bed, and various heat treatments were applied. The rotating bending fatigue test was performed on four sample groups comprising as-fabricated, age-treated, solution-treated and solution + age-treated conditions.

Originality/value
Most literature studies have focused on the axial fatigue strength, printing orientation and heat treatment of maraging steels produced with Direct Metal Laser Sintering (DMLS); many studies have also investigated crack propagation behaviors. There are few studies in the literature covering conditions of rotating bending fatigue. However, the rotating bending loading state is the service condition closest to modern machine element operating conditions. To fill this gap in the literature, the rotating bending fatigue behavior of the alloy, which was maraging steel (X3NiCoMoTi18-9–5, 1.2709) produced by SLM, was investigated under a variety of heat treatment conditions in this study.
Machining of Ti-6Al-4V biomedical alloy by WEDM: investigation and optimization of MRR and Rz using grey-harmony search
Authors: Sharma Neeraj , Gupta Rahul Dev , Khanna Rajesh , Sharma Rakesh Chandmal , Sharma Yogesh Kumar 
Published: August 2021

Purpose
The purpose of this paper is to investigate the optimized setting of wire-cut electrical discharge machining (WEDM) parameters at which material removal rate (MRR) and mean roughness depth (Rz) set a compromise. The problem in the processing of Ti-6Al-4V by conventional processes is a high strength, high hardness, high tool wear. Due to which WEDM is adopted to machine Ti-6Al-4V biomedical alloy. Ti-6Al-4V alloy has a number of applications in the engineering and medical industries due to its high strength biocompatibility.

Design/methodology/approach
The effect of control factors (i.e. pulse on-time: Pon; pulse off-time: Poff; servo voltage: SV) on the MRR and Rz is investigated in the present research. The planning of experiments is done using a Taguchi-based L9 orthogonal array. The percentage influence of each factor on responses is also evaluated. The multi-objective optimization is done using the grey approach initially. After that, the results were also calculated using harmony search (HS). Therefore, a hybrid approach of grey and HS is used to find the optimized values of MRR and Rz.

Findings
The maximum value of grade calculated by grey-HS is 0.7879, while in the case of the experimental run the maximum value of grey grade is 0.7239. The optimized setting after improvisation at this grade value is Pon: 130 µs; Poff: 45 µs and SV: 70 V for MRR and Rz collectively. The validation of the suggested setting is completed by experimentation. The values of MRR and Rz are coming out to be 6.4 mm3/min and 13.84 µm, which represents improvised results after the implementation of the HS algorithm.

Originality/value
The integration of the grey approach with the HS principle in the manufacturing domain is yet to be explored. Therefore, in the present research hybrid approach of grey-HS is implemented in the manufacturing domain having applications in medical industries.
Crop heterogeneity is positively associated with beneficial insect diversity in subtropical farmlands
Authors: Priyadarshana Tharaka S. , Lee Myung‐Bok , Ascher John S. , Qiu Lu , Goodale Eben 
Published: August 2021

Abstract

Increasing crop configurational heterogeneity—smaller crop fields with more field margins—has been repeatedly found to support farmland biodiversity. But research on compositional crop heterogeneity—the number and evenness of crop types—has usually shown only weak effects. However, much of this research has been conducted in large‐scale temperate agroecosystems.

We examined smallholder subtropical agroecosystems in southern China to assess the effects of crop heterogeneity on beneficial insect biodiversity. In addition to pollinators (bees, apoid and vespid wasps, and butterflies), we studied dung beetles and dragonflies/damselflies, which are not usually considered in cropland heterogeneity studies, but are abundant in these multi‐functional agroecosystems. We sampled these taxa in 468 transects placed inside 52 farms across three seasons (summer, spring and winter), collecting data on 27,245 insects belonging to 160 species.

We found a strong positive effect of crop compositional heterogeneity (measured by Shannon–Wiener index) on dung beetle and dragonfly/damselfly diversity. Bee/wasp and butterfly diversity, conversely, was positively affected by crop configurational heterogeneity (measured by cumulative field margin length).

Field margin type, categorized by the structure of the dominant crop types, was consistently an important explanatory variable, with weedy margins having high insect diversity. The presence of a vegetable crop on one side of the field margin, compared to non‐vegetable monocultures on both sides, increased diversity in 3/4 taxon‐season comparisons made for rice and 6/9 comparisons made for sugarcane or corn.

Synthesis and applications. We demonstrate that crop compositional heterogeneity can support insects that respond to differences among crop types, including taxa that play a key role in nutrient cycling (dung beetles) and natural pest control (dragonflies/damselflies). Incorporating structurally diverse crops into monoculture Asian agroecosystems can reduce the adverse effects these intensive systems have on beneficial insects, and increase crucial ecosystem services.
‘Some Very Queer Couples’: Gender Migrants and Intimacy in Nineteenth‐Century America
Authors: Bayker Jesse 
Published: August 2021

AbstractThis article contends that the term gender migrant – which describes a person who changed gender on a long‐term basis in their everyday life – offers a useful tool for grappling with the ambiguities of nineteenth‐century transgender history. Examining four cases of gender change that circulated in the popular press between the antebellum era and the turn of the twentieth century, the article brings to light intimate relationships that do not fit within the categories of female husbands or sexual inverts that have become familiar to historians of sexuality. Some female‐assigned gender migrants lived as men and sought same‐gender intimacy in the company of other men. Reading ambiguous cases of love and marriage from multiple angles provides insight into the strategies that resourceful gender migrants used to legitimise their public gender identities.
Candidate evaluations across the aisle: Cross‐cultural evidence that out‐partisans value candidate warmth more than in‐partisans
Authors: BOR ALEXANDER , LAUSTSEN LASSE 
Published: August 2021

AbstractPartisans view their own candidates through rose‐coloured glasses and see competing candidates much more negatively. However, recent advances in political behaviour reveal that such directional motivated reasoning is not simply about love and hate, but also about more nuanced shifts in preferences. Combining two insights from the psychological sciences – coalitional reasoning and a general dislike of self‐interested leaders – we form the novel prediction that voters pay more attention to out‐party than to in‐party candidates’ warmth. We show firm evidence for this prediction relying on election studies data with candidate warmth impressions from 27 elections from seven countries (Australia, Denmark, Germany, Norway, Sweden, the United Kingdom and the United States) between 1984 and 2016; and a re‐analysis of existing experimental data (total N = 140K). Our paper reveals sophisticated psychological mechanisms regulating the importance of candidate warmth and implies that candidates seeking to reduce the partisan gap should establish a warm image.
Applications of novel processing technologies to enhance the safety and bioactivity of milk
Authors: Soni Aswathi , Samuelsson Linda M. , Loveday Simon M. , Gupta Tanushree B 
Published: August 2021

AbstractBioactive compounds in food can have high impacts on human health, such as antioxidant, antithrombotic, antitumor, and anti‐inflammatory activities. However, many of them are sensitive to thermal treatments incurred during processing, which can reduce their availability and activity. Milk, including ovine, caprine, bovine, and human is a rich source of bioactive compounds, including immunoglobulins, vitamins, and amino acids. However, processing by various novel thermal and non‐thermal technologies has different levels of impacts on these compounds, according to the studies reported in the literature, predominantly in the last 10 years. The reported effect of these technologies either covers microbial inactivation or the bioactive composition; however, there is a lack of comprehensive compilation of studies that compare the effect of these technologies on bioactive compounds in milk (especially, caprine and ovine) to microbial inactivation at similar settings. This research gap makes it challenging to conclude on the specific processing parameters that could be optimized to achieve targets of microbial safety and nutritional quality at the same time. This review covers the effect of a wide range of thermal and non‐thermal processing technologies including high‐pressure processing, pressure‐assisted thermal sterilization, pulsed‐electric field treatment, cold plasma, microwave‐assisted thermal sterilization, ultra‐high‐pressure homogenization, ultrasonication, irradiation on the bioactive compounds as well as on microbial inactivation in milk. Although a combination of more than one technology could improve the reduction of bacterial contaminants to meet the required food safety standards and retain bioactive compounds, there is still scope for research on these hurdle approaches to simultaneously achieve food safety and bioactivity targets.
