Numerical and experimental studies of thermal performance enhancement for parabolic trough solar collector using none-circulated CuO/synthetic oil nanofluid
Authors: Elmnefi Mohamed , Al-Khazraji Waqas 
Published: June 2023

Purpose
One of the existing and commonly used solar energy harvesting devices is the parabolic trough solar collector (PTSC). Because of their ability to operate in low and medium temperatures, parabolic trough concentrators are widely used in power generation plants and industrial process heating applications. Therefore, the investigation of how different operating conditions affect these devices’ overall efficiency has received a great deal of attention in the recent decade. This study aims to enhance the thermal performance of the PTSC and reduce the system cost.

Design/methodology/approach
In the novel configuration, a noncirculated nanofluid absorbs solar radiation through a glass wall. The base fluid was synthetic oil (5W30), and the nanoparticles used were copper oxide. The heat captured is immediately absorbed by the water circulating inside the copper tube immersed in the nanofluid. ANSYS FLUENT 15.0 was used for carrying out computational fluid dynamics simulations for two models of single and triple copper tubes. The experimental results obtained from a test rig constructed for this purpose were compared with the numerical outcomes of the single copper tube model.

Findings
The findings of the simulation demonstrated that performance was superior for the single copper tube model over the triple copper tube model. The numerical findings of the single copper tube model were compared with the experimental results. The numerical and experimental results differed from 3.17% to 5.6%. Investigations were carried out to study the effects of varying the volumetric flow rate of (20, 40, 60 and 80 L/h) and water inlet temperatures of (300, 315 and 330 K) on the effectiveness and performance of the newly developed model. Additionally, two nanofluid volume fractions of 0.05% and 0.075% were used for investigating their effect on the performance of the novel configuration. According to the findings, the highest thermal efficiency of 55.31% was recorded at 0.075% concentration and 80 L/h volume flow rate.

Originality/value
In this study, a novel direct absorption solar collector configuration using a noncirculated nanofluid was designed to enhance the thermal efficiency of PTSC. This new approach makes it possible to boost the thermal performance of the PTSC and lower the system’s cost.

Examining the effects of CSR on organizational attractiveness: perception study of job seekers in India
Authors: Ali Esrafil , Satpathy Biswajit , Gupta Deepika R. 
Published: June 2023

Purpose
The purpose of this paper is to study the effect of corporate social responsibility (CSR) effectiveness on job seekers’ organizational attractiveness (JSA). Deriving inspiration from Carroll’s theory, the study specifically tries to measure the impact of CSR on JSA with the four dimensions pertaining to economics (PECO), pertaining to legal compliance (PLCO), pertaining to ethics (PETH) and pertaining to philanthropic (PPH). Furthermore, the paper also tries to examine the moderating role of company selection (COM SEL) done based on high or low CSR reputation and JSA.

Design/methodology/approach
Management and engineering students enrolled in premier institutions and universities of Western Odisha in India are surveyed for their perceptions of CSR and JSA. Purposive and convenience sampling are applied to collect data from 456 job seekers. Based on the analysis, the study proposes two main models (Models 1 and 2) wherein Model 1 tries to measure the effect of CSR on JSA and Model 2 checks the moderating effect of COM SEL on CSR and JSA. In addition, robustness of the study is tested using control variables (Models 3 and 4). Data is treated through SmartPLS 3.3 software. The structural equation modelling (partial least squares-SEM) method is applied to test the hypotheses and for further analysis.

Findings
The result reveals an interesting insight. There is a positive and significant effect of PECO, PLCO and PPH on JSA. Moreover, no such significant effect is observed between PETH and JSA. Further, the findings are contrary with respect to COM SEL, that partially moderates the effect of CSR on JSA. However, the results reveal that COM SEL has a substantial moderating effect on the PPH dimension of CSR and JSA.

Practical implications
The results highlight that CSR positively and significantly affects JSA in terms of PECO, PLCO and PPH, thereby emphasizing that organizations must be more focused on these perspectives of CSR. Further, though the results did not exhibit any significance with PETH, it is essential that organizations should strengthen the ethical aspects of CSR as well and align them with the CSR strategic actions. The study also confirms the moderating effect of COM SEL on PPH dimension of CSR and JSA, thereby supporting the philanthropic approach in this domain. Further, the organizations should foresee the philanthropic factor of CSR as a competitive advantage to attract potential job seekers.

Originality/value
This research attempts to contribute to CSR and HR literature in two ways. First, it is the first attempt to use PLS-SEM with an attempt to understand job seekers’ perception of CSR and JSA with Indian data consisting of students belonging to premier business management and engineering institutes. Second, the study is an attempt to empirically measure the moderating effect of COM SEL on JSA. To sum up, the study will provide insights to organizations to help craft CSR strategies for attracting more job seekers.

Authors: Xue Pengsongze , Jo WooMi 
Published: June 2023

PurposeAlthough various booking platforms have been contributing to the dramatic growth of hotel industry, little research has been conducted to understand consumer psychological processes and behaviors in online hotel booking. To fill this gap, the current study examines the effect of switching barriers (switching cost and alternative attractiveness) on consumers' decision postponement and repurchase intention. Additionally, the moderating effect of time pressure in different phases of booking decision is investigated.Design/methodology/approachA total of 352 samples was collected through an online platform. Data analysis was conducted via Amos 23 (structural equation modeling) and SPSS 24 (descriptive analysis and PROCESS macro).FindingsResults show that switching cost and alternative attractiveness are two significant drivers of decision postponement and repurchase intention. Meanwhile, time pressure only has a significant moderating effect on the relationship between switching cost and decision postponement.Practical implicationsThe findings of this research reveal that hotel operations need to implement strategies to prevent customers' delayed booking decisions and overcome the influence of time pressure on customer decision-making.Originality/valueThese findings stress the importance of consumer perceptions of switching barriers and time span when making hotel reservations online. Hotel practitioners are encouraged to provide multiple human–computer interaction applications to attract novice consumers and increase their familiarity with booking process.
A feasibility study to identify the presence of autism specific risk factors in secure services using an autism specific framework
Authors: Skelhorn Esther , Girardi Alessandra , Cooper-Evans Sam 
Published: June 2023

Purpose
Some individuals with autism may engage in violent behaviour. Research into autism specific factors (ASFs) that may contribute to violence is limited. The purpose of this paper is to explore the feasibility of use of an ASF framework which was developed to inform risk formulation and treatment needs.

Design/methodology/approach
Retrospective identification and evaluation of ASFs in offenders with autism (N = 13) at childhood, time of index offence and in current risk behaviours. The ASFs described in the framework were repetitive behaviours and circumscribed interests; poor social understanding and empathy; sensitivity to sensory stimulation; and disruption to rigid behavioural routines or difficulties coping with change.

Findings
There was evidence for all four ASFs being consistently present in childhood, contributing to violent behaviour at the index offence and current risk behaviours in at least one case. Poor social understanding and empathy was often present at both childhood and index offence in all cases. Of the seven cases with offence paralleling behaviour, five had at least one ASF present at each timepoint.

Practical implications
This proof-of-concept study provides initial support that ASFs play a role in offending behaviour of individuals with autism. Clinicians working in specialist and generic forensic services, with an in-depth knowledge of autism, could use the ASF framework to enhance risk assessments and facilitate more targeted treatment planning for offenders with autism in specialist and general forensic services.

Originality/value
To the best of the authors’ knowledge, this study is the first to test the application of the ASF framework in an autistic offending population.

The production and pricing strategy of the two-echelon remanufacturing supply chain with government subsidy under patent protection
Authors: Cao Xiaogang , Wen Hui , Cao Bowei 
Published: June 2023

PurposeIn this paper, the authors study the production and pricing decisions of a remanufacturing supply chain composed of a supplier, an assembler and a remanufacturer, in which the remanufacturing of components requires patent licensing from the supplier.Design/methodology/approachThe authors consider three different models with government subsidy for remanufacturing: (1) no government subsidies; (2) the government subsidizes the remanufacturing behavior of the supplier and (3) the government subsidizes the remanufacturing behavior of the remanufacturer and use the Stackelberg game model to solve and analyze the equilibrium wholesale prices of components and the equilibrium outputs of new and remanufactured products under three subsidy modes.FindingsThe results show that the equilibrium wholesale prices of two kinds of components decrease with the unit patent licensing fee and the unit government subsidy, and the equilibrium quantity of the remanufactured products under the three modes is obviously higher than that of the new products.Originality/valueFinally through numerical simulation, it is found that the equilibrium profits of the supplier, the manufacturer and the supply chain increase monotonously in relation to the unit government subsidy, while the optimal profit of the assembler in relation to the unit government subsidy tends to decrease first and then increase.

“I would want to see young people working in here, that’s what I want to see…” how peer support opportunities in youth offending services can support a Child First, trauma-informed, and reparative model of practice for youth justice
Authors: Thompson Naomi , Spacey Meghan 
Published: June 2023

Purpose
This paper aims to explore how peer support can support a combined Child First, trauma-informed and restorative approach for youth justice. While other scholars have identified clashes between these approaches, particularly between Child First and restorative approaches, a focus on reparative practice with peers has been under-explored as a more child-centred model for reparation-focused work.

Design/methodology/approach
We draw on qualitative data from interviews and surveys undertaken with young people and parents/caregivers in a London youth offending service (YOS). The data was part of a broader mixed-methods study in the YOS that used observational methods alongside surveys and interviews to evaluate the effectiveness of its model of practice. Peer support emerged as a theme.

Findings
Participants expressed the desire to see young people working and volunteering in the YOS and felt this would help make it a safe and non-threatening space. Young people who had completed their time with the YOS saw themselves as role models with the insight and skills to support others. These young people expressed a strong desire to work in the YOS and, in some cases, to develop long-term careers supporting young people.

Originality/value
Our research challenges the notion that young people who have been involved in crime struggle to empathise, providing rich examples of their empathic understanding for peers. Peer support opportunities could offer a reconceptualisation of restorative practice that is Child First and trauma-informed. Such opportunities would benefit both the young people being supported and those offering support, building a co-produced approach that is directly informed by the expressed needs and desires of the young people.
A call for critical PDS: infusing DisCrit into the nine essentials
Authors: Damiani Michelle L. , Elder Brent C. 
Published: June 2023

PurposeThe field of Professional Development Schools (PDS) continues to evolve with promising implications. As part of advancing practice, the National Association for Professional Development Schools has updated its nine essential guiding principles, which now includes an explicit expectation for all PDS partners to advance equity, anti-racism and social justice. This article is a call for critical professional development work which infuses Disability Critical Race Theory (DisCrit) practices into achieving the Nine Essentials.Design/methodology/approachIn this call-to-action article, the authors argue that it is imperative for the whole of PDS work to establish a priority for inclusive practice that recognizes and responds to all aspects of diversity in education from the outset, including disability. The authors suggest that PDS work must be guided by an intersectional approach that is operationalized to achieve equity in education by dismantling both racism and ableism in education. The authors use an action-based example from our PDS work to exemplify these elements in practice.FindingsIn this article, the authors put forth two arguments that they urge their PDS colleagues to consider. First, the authors call for practices within PDS to give attention to improving student learning in ways that specifically address disability and intersectional considerations related to disability. Second, the authors urge that PDS work must be conceptually and practically inclusive in order to achieve the social justice impact put forth in the comprehensive mission of the Nine Essentials.Originality/valueThere is a growing body of literature around PDS that addresses theory to practice research and best practices in PDS settings. While some recent publications address inclusive PDS practices, the authors were not able to identify any works related to DisCrit in the PDS literature to date.
Investigation on pore properties, thermal conductivity, and compressive behavior of fly ash/slag‐based geopolymer foam
Authors: Zhou Huafei , Xu Zhechen , Xie Ziling , Hong Hengda 
Published: June 2023

AbstractGeopolymer foam has emerged as a promising inorganic porous material in the last decade. Despite of the numerous advantages, there are some pending issues to be addressed, on top of that is the low compressive strength. To overcome this, this study synthesizes a high‐strength geopolymer foam by the partial substitution of fly ash (FA) with ground granulated blast furnace slag and carries out an intensive investigation into its microstructure, pore properties, thermal conductivity as well as compressive behavior. The microstructure is firstly analyzed by X‐ray diffraction and Fourier transform infrared spectroscopy techniques. The pore characteristics are also scrutinized, including pore size distribution, total porosity and water absorption. Then, the thermal conductivity is investigated and the applicability of basic effective thermal conductivity models to characterize the relationship with total porosity is evaluated. Afterward, the compressive strength together with the softening coefficient is examined, and the relationship with total porosity is also studied. Finally, comparisons between the proposed geopolymer foam and other FA‐based geopolymer foams in the literature are performed. The results show that the proposed geopolymer foam possesses not only a comparable thermal conductivity but also a far superior compressive strength, which sheds light on the widespread applications in thermal insulation.
Comparison of the Hysteresis Response of Super-Coiled Polymer Actuators
Authors: Henry Josh H. P. , Bridge Jacqueline 
Published: June 2023

Abstract
In recent years, super-coiled polymer (SCP) actuators have been investigated as a higher yield, low-cost alternative to conventional actuators. A major challenge has been finding appropriate general and industry uses for these actuators due to their hysteretic response. This paper seeks to compare the response for SCP actuators based on different thread weights and sizes and thus suggest possible directions for their use. The actuators were produced through coiling and heat training controlled via Arduino. The responses were obtained by supplying a controlled voltage to the system. The response was filmed and processed using matlab; the resulting displacement and strain were used to observe the hysteretic characteristics. Based on the characteristics noted, different applications were recommended for these SCP actuators. It is recommended that this research into SCP actuators be furthered by developing hysteresis models for compensation, control, and exploring their use in robotic systems and tactile mechanisms.
