Authors: Doyle Michael Francis , Williams Megan , Butler Tony , Shakeshaft Anthony , Conigrave Katherine , Guthrie Jill 
Published: August 2021

Purpose
The purpose of this study is to describe what a sample of men in prison believe works well for the delivery of prison-based group alcohol and other drug (AoD) treatment programs. The authors hope the findings will help inform future practise in AoD program delivery in prison.

Design/methodology/approach
A qualitative research paper reporting on a thematic analysis of in-depth interviews with 30 male prisoners on their perspectives on AoD group treatment approaches.

Findings
Results indicate that matching readiness and motivation to start treatment is important for group success. Program content must be relevant and delivered by empathic facilitators who maintain confidentiality. It would be advantageous if one of the program facilitators was a peer with personal experience of overcoming an AoD use disorder.

Originality/value
According to the authors’ knowledge, this is one of few qualitative studies into the delivery of AoD treatment for men in prison and the only study of its kind in Australia. The consumer perspective is an important element in improving quality of treatment provision.
Performance evaluation of GPU- and cluster-computing for parallelization of compute-intensive tasks
Authors: Döschl Alexander , Keller Max-Emanuel , Mandl Peter 
Published: August 2021

PurposeThis paper aims to evaluate different approaches for the parallelization of compute-intensive tasks. The study compares a Java multi-threaded algorithm, distributed computing solutions with MapReduce (Apache Hadoop) and resilient distributed data set (RDD) (Apache Spark) paradigms and a graphics processing unit (GPU) approach with Numba for compute unified device architecture (CUDA).Design/methodology/approachThe paper uses a simple but computationally intensive puzzle as a case study for experiments. To find all solutions using brute force search, 15! permutations had to be computed and tested against the solution rules. The experimental application comprises a Java multi-threaded algorithm, distributed computing solutions with MapReduce (Apache Hadoop) and RDD (Apache Spark) paradigms and a GPU approach with Numba for CUDA. The implementations were benchmarked on Amazon-EC2 instances for performance and scalability measurements.FindingsThe comparison of the solutions with Apache Hadoop and Apache Spark under Amazon EMR showed that the processing time measured in CPU minutes with Spark was up to 30% lower, while the performance of Spark especially benefits from an increasing number of tasks. With the CUDA implementation, more than 16 times faster execution is achievable for the same price compared to the Spark solution. Apart from the multi-threaded implementation, the processing times of all solutions scale approximately linearly. Finally, several application suggestions for the different parallelization approaches are derived from the insights of this study.Originality/valueThere are numerous studies that have examined the performance of parallelization approaches. Most of these studies deal with processing large amounts of data or mathematical problems. This work, in contrast, compares these technologies on their ability to implement computationally intensive distributed algorithms.
Vegetable oil-based cutting fluids and its behavioral characteristics in machining processes: a review
Authors: Pranav P. , Sneha E. , Rani S. 
Published: August 2021

Purpose
This paper aims to provide a detailed review of various cutting fluids (CFs).

Design/methodology/approach
Friction and wear are inevitable in machine parts in motion. The industrial sector uses various kinds of lubricants, which include engine oils, CFs, hydraulic fluids, greases, etc. to control friction and wear. The main purpose of using CF is to remove heat produced during machining and to reduce cutting forces, tool wear and energy associated with it. Thus, it increases the productivity and quality of the manufacturing process. But more than 80% of the CFs used in the industries now are mineral oil-based. These mineral oils and additives are highly undesirable because of their toxicity, nonbiodegradability, pollution and ecological problems. Hence, these petroleum-based oils in the lubrication system can be substituted with alternatives such as vegetable-based CF. Several studies are being conducted in the field of eco-friendly CFs. Because of the variance in fatty acid profile and availability, the selection of vegetable oils (VOs) is another problem faced nowadays. The present study is focused on bio-based oils and many eco-friendly additives. Various machining processes and comparisons relating to the same have also been made. The aim is to minimize the use of mineral oil and thereby introduce sustainability in production.

Findings
In this present study, bio-based oils, additives and various characteristic behavior of them in machining are being discussed. The VOs are found to be a potential base oil for industrial CFs.

Originality/value
This paper describes the importance of sustainable CFs.
From university social-responsibility to social-innovation strategy for quality accreditation and sustainable competitive advantage during COVID-19 pandemic
Authors: Adel Heba Mohamed , Zeinhom Ghada Aly , Younis Raghda Abulsaoud Ahmed 
Published: August 2021

PurposeThe purpose of this study is to investigate conceptually and empirically the direct and indirect relationships between university social responsibility (USR), university social innovation strategy (USIS) in terms of social awareness (SA), intention for social innovation (ISI), organisational structure for social innovation (SSI) and innovativeness in social value creation (ISVC) and gaining a sustainable competitive advantage (SCA) at quality-accredited faculties of an emerging market.Design/methodology/approachA conceptual model was presented and a mixed-methods approach was exploited to fill a research gap detected in strategic corporate social innovation literature. The authors formed a data collection team that contacted all the quality-accredited public and private/international faculties, of which 109 faculties in 11 Egyptian governorates responded and their quality units filled questionnaires that were analysed by structural equation modelling. For comprehensive understanding, qualitative interviews were set to gather data from managers/leaders and teaching staff working at those faculties in quality management and community engagement practices as well as students.FindingsResults demonstrated that USR positively and significantly influenced SCA and USIS. Further, USIS (in terms of ISI, SSI and ISVC) positively and significantly influenced SCA. However, USIS (in terms of SA) had a positive yet insignificant influence on SCA. Indirectly, USIS was found to be partially mediating USR–SCA relationship.Practical implicationsUniversity leaders/staff can gain insights on how to adopt differentiation strategies, which enable their institutions to shift from being just socially responsible to becoming socially innovative by presenting solutions to social, economic, cultural, environmental and health-care problems/challenges within their communities in general and during pandemics. This can be sustained through developing innovative quality-based processes/programmes/services related to education, research and community outreach that better serve social needs to be quality-accredited and unique over their rivals.Social implicationsSatisfying social needs through promoting innovative processes/services can reinforce a favourable social change.Originality/valueFrom a cross-disciplinary perspective, the authors interwove conceptually sparse literature of strategic, operations, knowledge capacity and innovation management that studied university social innovation research area. Also, to the best of the authors’ knowledge, this is the first research that examined empirically USR–USIS–SCA relationships of quality-accredited faculties in an emerging economy during Covid-19 pandemic.
The knowledge hiding loop: exploring the boundary conditions
Authors: Sun Yunpeng , Ayub Arslan , Fatima Tehreem , Aslam Hassan Danial , Bahoo Salman 
Published: August 2021

PurposeUsing norms of reciprocity, this study explores how employees' exposure to workplace ostracism (WO) affects their task performance through the mediating role of knowledge hiding (KH). Moreover, drawing on social identity theory, this research outstretches the boundary conditions of KH, i.e. under which KH is less likely to occur.Design/methodology/approachTime-lagged, multisource data collected from 297 employees in service sector organizations in Pakistan were analyzed using SMARTPLS (v 3.3.3).FindingsThe findings reveal that perception of WO provokes KH behavior in employees, which, in turn, deteriorates their task performance. Results also disclose that moral identification (MI) and organizational identification (OI) buffer against the positive association between WO and KH, such that the ostracism-KH link is weaker at higher levels of MI and OI, and vice versa.Practical implicationsThe study envisages that a KH loop occurs between the knowledge hider and the knowledge seeker, which fosters spirals of conflict that might prevail in organizations over an extended period of time. Therefore, the occurrence context of KH should be mitigated through appropriate managerial interventions. In addition, nurturing self-identities will be beneficial for both employees and organizations.Originality/valueThis is the first study that investigates the relationship between WO and task performance while also considering the mediating role of KH and the moderating roles of MI and OI.
Doctoral writing: learning to write and give feedback across cultures
Authors: Carter Susan , Sun Qiyu , Jabeen Farrah 
Published: August 2021

Purpose
This study aims to broaches several endemic challenges for academics who support doctoral writing: writers are emotionally protective of their own writing; writing a thesis in English as a second language is a challenging, complex task; and advising across cultures is delicate. Giving constructive feedback kindly, but with the rigour needed to raise writing quality can seem daunting. Addressing those issues, the authors offer a novel way of working with writing feedback across cultures.

Design/methodology/approach
The case study research team of two candidates and one supervisor stumbled onto an effective way of working across cultural and institutional difference. What began as advisory feedback on doctoral writing became an effective collaborative analysis of prose meaning-making. The authors reflected separately and collectively on how this happened, analysed reflections and this narrative inquiry approach led to theories of use to writing feedback practice.

Findings
The authors cross between theory and praxis, showing that advisors and supervisors can create Bhabha’s post-colonial third space (a promising social space that sits between cultures, beyond hierarchies, where new ways of thinking can be collaboratively generated) as a working environment for international doctoral writing feedback. Within this zone, Brechtian alienation, a theory from theatre practice, is applied to prompt emotional detachment that enables focus on writing clearly in academic English.

Research limitations/implications
Arguably the writing feedback session the authors described remains bound by the generic expectations of a western education system. The study is exegetical, humanities reading of practice, rather than a social science gathering of empirical data. Yet the humanities approach suits the point that a change of language, attitude and theory can give positive leverage with doctoral writing feedback.

Practical implications
The authors provide a novel practical method of supporting international doctoral candidates’ writing with feedback across cultures. It entails attracting the writers’ interest in theory and persuading them, via theory, to look objectively and freshly at their own writing. Also backed by theory, a theoretical cross-cultural space allows for discussion about differences and similarities. Detachment from proprietorial emotions and cross-cultural openness enables productive work amongst the mechanics of clear academic English text.

Originality/value
Underpinned by sociocultural and metacognitive approaches to learning, reflection from student and supervisor perspectives (the data), and oriented by theory, the authors propose another strategy for supporting doctoral writing across cultures. The authors demonstrate a third space approach for writing feedback across cultures, showing how to operationalise theory.
How the past becomes the past: The temporal positioning of collective memory
Authors: Adams Tracy , Edy Jill A. 
Published: August 2021

AbstractRecognizing that the past does not necessarily pass of its own accord but rather is made to pass is crucial for understanding relationships between collective memory, temporality and the past. Analyzing processes of temporal negotiation reveals that changing the ending (or, in some cases creating one at all) requires re‐envisioning the entire sequence of events. Thus, the ending (if there is one) depends on the beginning. British prime ministers' references to 9/11 in public addresses demonstrate this process of temporal negotiation about whether and how to create an ending. Tony Blair constructed the attacks as a legacy, thus sustaining the past as part of the present. To unwind this construction and consign 9/11 to the past, Gordon Brown and David Cameron needed to disrupt the flow of contingent incidents in which Blair had embedded 9/11. By redefining the narrative's beginning, they made it possible to bring 9/11 to an end.

Authors: Pickens Gary T. , Moore Brian , Smith Mark W. , McDermott Kimberly W. , Mummert Amanda , Karaca Zeynal 
Published: August 2021

AbstractObjectiveTo evaluate and compare approaches to estimating the service delivery cost of emergency department (ED) visits from total charge data only.Data SourcesThe 2013–2017 Healthcare Cost and Utilization Project's (HCUP) State Emergency Department Databases (SEDD) and the Centers for Medicare and Medicaid Services Healthcare Cost Report Information System (HCRIS) public use files.Study DesignCompare a baseline approach (requiring cost‐center‐level charge detail) and four alternative methods (relying on total charges only) for estimating ED visit costs. Estimation errors are calculated after applying each method to a sample of ED visits, treating estimates from the baseline approach as the “true” cost. Performance metrics are calculated at the visit and hospital levels.Data Collection/Extraction MethodsThe charges, revenue center codes, and patient/hospital characteristics were extracted from the SEDD. Detailed costs and charges were extracted from HCRIS public use files.Principal FindingsBaseline (“true”) ED visit costs increased from $383 to $420 per visit between 2013 and 2017. Three methods performed comparatively well estimating mean cost per visit. The method using an overall cost‐to‐charge ratio (CCR) for all ancillary cost centers without regression adjustment (ANC‐CCR) performed the worst, overestimating “true” costs by $63–$113 per visit. The other three methods, which used CCRs computed from selected cost centers, exhibited much smaller bias, with two of the methods yielding estimates within $2 of the “true” cost in 2017. Compared with ANC‐CCR, the other three methods had more compact estimation error distributions. The estimated mean visit costs from all four methods have relatively small statistical variance, with 95% confidence intervals for mean cost in a hospital with 25,000 ED visits ranging between $4 and $7.ConclusionsWhen cost‐center‐level charge detail for ED visits is unavailable, alternative methods relying on total ED charges can estimate ED service costs for patient and hospital segments.
Police brutality and unmet need for mental health care
Authors: Alang Sirry , Rogers Taylor B. , Williamson Lillie D. , Green Cherrell , Bell April J. 
Published: August 2021

AbstractObjectiveNational movements have raised awareness of the adverse mental health effects of police brutality. This study examines the relationship between perceived police brutality and unmet need for mental health care.Data SourcesWe used the 2018 Survey of the Health of Urban Residents (N = 4338), a quota sample survey of adults in urban areas in the contiguous United States.Study DesignMultivariate regressions were used to understand the association between police brutality and unmet need for mental health care. Unmet need was regressed on police brutality (the independent variable), controlling for sociodemographic and health status characteristics of respondents and access to care. We then stratified the sample by experiences of police brutality (no negative encounters with the police, encounters that were perceived as necessary, and encounters that were considered unnecessary) and described how medical mistrust and perceived respect within health care settings were associated with odds of unmet need for each subsample.Data CollectionData were collected online.Principal FindingsNegative police encounters perceived as necessary were associated with greater odds of unmet need compared to no negative police encounters (odds ratio [OR] = 1.98, confidence interval [CI] = 1.30–2.65). Odds of unmet need were also higher among persons with negative and unnecessary police encounters (OR = 1.28, CI = 1.05–1.56). Greater respect was associated with lower odds of unmet need among persons who reported negative unnecessary encounters with the police (OR = 0.88, CI = 0.72–0.97). Medical mistrust was associated with greater odds of unmet need among those with negative unnecessary police encounters (OR = 1.52, CI = 1.12–1.93).ConclusionsPersons who are exposed to police brutality are also likely to be those who experience unmet need for mental health care. Ensuring that they feel respected within medical settings and establishing conditions that build trust in medical institutions are important for eliminating unmet need for mental health care.
From Ghana to India, Saving the Global South’s Mothers with a Digital Solution
Authors: Al Dahdah Marine 
Published: August 2021

AbstractWith the widespread use of mobile phones in the Global South, digital tools are attracting growing interest from international aid actors as well as local governments – positioning digital technology as an essential driver of economic growth and an obvious solution to many social problems. Initiated by multiple actors from the digital industry, these programs reconfigure the state, the rights of citizens, the perimeter and access to health services. Through the study of the Motech Global Mobile Health Program (mHealth) implemented in Ghana and India to improve maternal health, this paper explores the way in which processes of medical globalization and privatization come into being through digital technology. It shows how forms of philanthrocapitalism drive such digital programs. By confronting the stories of the techy philanthropists promoting such solutions and the global south’s mothers that are supposedly benefiting from it, this paper also illustrates the gap between the promise of better healthcare offered by such digital solution and the realities experienced on the ground by its users, on gender and empowerment issues or accessibility and quality of healthcare.
The Appropriated Body: Biometrics Regime, The Digital State and Healthcare in Contemporary India
Authors: Mishra Rajiv K. 
Published: August 2021

AbstractThe sheer size of the Indian population and its presence in a gigantic biometrics database has made possible the appropriation and control of millions of bodies on an everyday basis. It is being done at different levels by players operating the Digital State, with a markets‐based approach aiming to provide governance and development entitlements, healthcare being one among them. However, at the receiving end of this appropriative force are the 22 percent below poverty line (BPL) population, accounting for around 300 million people living at less than 1.25 dollars per day. These tend to be bodies facing a double jeopardy of historical‐social‐economic inequalities and negotiating the biometric means of accessing healthcare entitlements. Specifically, this refers to an arduous process of proving one's 'mistrusted' self to be able to enter the process of availing medical treatment. Based on qualitative fieldwork in Jharkhand and Delhi, the paper argues that the very process of biometrics‐based access to healthcare appropriates the bodies of BPL families even before they get any medical treatment. Findings reflect that the biometrics (technological) means for identifying the mistrusted bodies of BPL populations adds to the existing social inequalities.

Published: August 2021

AbstractThe aim of this study was to measure the initial and remaining dentin thickness in the danger zone of the second mesiobuccal (MB2) canal of maxillary first molars after rotary instrumentation using cone beam computed tomography (CBCT) imaging. After determining initial dentin thickness, each sample was subjected to a standardized protocol of rotary instrumentation files: ProTaper Gold Sx Orifice Opener (maximum depth of 7 mm); Vortex Blue 15.04, 20.04, 25.04, ProTaper Gold S1, S2, F1, F2, and finally Vortex Blue 30.06. Subsequent CBCT measurements were made to compare changes in remaining dentin thickness in comparison to initial presentation. Preoperative dentin thickness in the danger zone had a mean of 0.82 ± 0.17mm. Significant levels of dentin removal in the danger zone were noted after all instrumentation groups when compared to the pre‐instrumentation mean (Sx P < 0.001, 25.04 P < 0.0006, F2 P < 0.0001, 30.06 P < 0.0001). It was concluded that a thin area of dentin exists along the distal wall of the MB2 (danger zone) from the furcation to 4 mm apically.

SummaryFat deposition is an important economic trait in farm animals. However, it is difficult to genetically improve intramuscular fat deposition via trait‐based cattle breeding. The main objectives of this study were to analyze the factors about beef flavor, and to detect functional microRNA (miRNA, miR) associated with intramuscular fat deposition in Yanbian cattle. Longissimus dorsi samples from six steers were separated into high‐ and low‐fat groups (n = 3 each) based on the marbling score, and transcriptomic analysis was performed using miRNA sequencing. A total of 33 miRNAs and 38 genes were found to be differentially expressed in the high‐ and low‐fat groups. Quantitative real‐time polymerase chain reaction was performed to validate the sequencing results. Integrated miRNA–mRNA analysis revealed that miRNA‐associated target genes were primarily associated with skeletal muscle development. However, some of the miRNAs (miR‐424 etc.) and genes (ATF3 etc.) were also associated with fat metabolism. A targeted relationship between miR‐22‐3p and the WFIKKN2 gene and its involvement in adipocyte differentiation were confirmed experimentally. The study findings may provide potential candidate molecular targets for the selection of cattle with improved meat quality.
