Published: February 2021

PurposeUnderstanding factors that enhance participants' satisfaction has become critical to developing effective donor retention strategies for charity sport events (CSEs). However, there is a lack of empirical research on participants' satisfaction with CSEs. The purpose of this study is to examine the antecedents and consequences of satisfaction among CSE participants and to empirically test the relationships between the proposed constructs.Design/methodology/approachData were collected from 238 participants from four Relay For Life (RFL) events organized by the American Cancer Society, North Central Region in the USA. Confirmatory factor analysis and structural equation modeling were conducted to analyze the measurement model and the structural model.FindingsThe results of the structural model indicated that perceived prosocial impact, sense of community and trust in CSE had significant positive effects on CSE satisfaction, while venue quality, knowledge attainment and entertainment value did not positively influence CSE satisfaction. CSE satisfaction had a positive direct effect on participant loyalty to CSE, which had a significant contribution to future participant intent.Practical implicationsThe findings of this study provide CSE directors and marketers with valuable insights into the process of how to build long-term relationships with participants by identifying factors that influence participants' satisfaction and its consequences.Originality/valueBy measuring the mediating role of CSE satisfaction, this study provides a deeper understanding of the causal pathways from the antecedents to participant loyalty through CSE satisfaction.
Intrusion detection in mobile ad-hoc network using Hybrid Reactive Search and Bat algorithm
Authors: Srilakshmi R. , Muthukuru Jayabhaskar 
Published: February 2021

PurposeThe mischievous nodes that defy the standard corrupt the exhibition of good nodes considerably. Therefore, an intrusion discovery mechanism should be included to the mobile ad-hoc network (MANET). In this paper, worm-hole and other destructive malignant attacks are propelled in MANET.Design/methodology/approachA wireless ad-hoc network also called as mobile ad-hoc network (MANET) is a gathering of hubs that utilizes a wireless channel to exchange information and coordinate together to establish information exchange among any pair of hubs, without any centralized structure. The security issue is a major difficulty while employing MANETs.FindingsConsequently, the attacks due to the malicious node activity are detected using Hybrid Reactive Search and Bat (HRSB) mechanism to prevent the mischievous nodes from entering the network beneath the untruthful information. Moreover, the attack detection rate and node energy are predicted for determining the lifetime of the node.Originality/valueThe simulation outcomes of the proposed HRSB technique are evaluated with the prevailing methods. The comparison studies have proven the efficacy of the current research model by attaining high attack detection rate and achieving more network lifetime.
Evolution of public-private partnership: the UK perspective through a case study approach
Authors: Adamou Marios , Kyriakidou Niki , Connolly Jon 
Published: February 2021

Purpose
Since the 1990s, the National Health Service (NHS)advisory officers have developed considerable expertise in managing the process of specifying, procuring, contracting and running public–private partnership (PPP) projects. However, there has been a relatively consistent trajectory in the findings of studies and evaluation of PPP from its initial introduction in the health sector in 1992 to the present time. Therefore, the purpose of this study is to critically evaluate the PPP experience in the UK context using a case study in the NHS.

Design/methodology/approach
The partnership literature is primarily focussed on process issues, and the impact of partnerships on improving outcomes cannot be assumed. By conducting a critical review on most updated research studies and innovative approaches in this area, the literature as to the place of PPPs in health in the context of the UK is critically explored and whether they have a role in system resilience is examined. A case study has be used as well to describing the processes of a PPP arrangement.

Findings
Health-care PPP is one of the options relating to health system resilience. However, their contribution in the NHS has been mixed, with success noted in short-term clinical and services contracts while in the long-term the value for money argument has not been proven. In theory, the role of PPPs in bringing together ingredients supporting system resilience such as finance, management and innovation in the UK has not always been successful, and NHS providers have taken the approach to exit such arrangements.

Research limitations/implications
More research work is needed to capture the 21st-century challenges and critical success factors during its implementation.

Practical implications
The creation of strong partnerships is moving service delivery away from a project-by-project approach to one that includes strategic and policy developments for long-term results.

Originality/value
This is a fresh discussion in the role of PPP in system resilience in the UK perspective through a case study describing an exit from a PPP arrangement.
Assessment of solid waste management practice in the university campus
Authors: Dahlawi Saad , El Sharkawy Mahmoud F. 
Published: February 2021

Purpose
Municipal solid waste (MSW) consists mainly of several recyclable materials such as paper and cardboard. Inside the educational institutes, especially universities, MSW is generated from several facilities including offices and cafeterias. Without an effective management program, solid waste can have detrimental impacts on the environment. This paper aims to assess the solid waste management practices followed at the main campus of Imam Abdulrahman Bin Faisal University (IAU), Dammam – Saudi Arabia.

Design/methodology/approach
The MSW samples were collected from different sources inside the IAU campus such as the college buildings (such as the teaching rooms and staff offices), the administrative buildings and services buildings (e.g. the main library, the photocopying center, the restaurant and cafeteria) at least one time per week during a full academic term (January–May) of the academic year 2017–2018. The collected MSW samples were segregated into seven categories, and the net amount of each category and the overall weight of the MSW were determined once every week. The MSW samples were characterized for physical and chemical properties including moisture, carbon and ash contents. Food product waste (FPW) of the main university restaurant was studied separately.

Findings
Data on the composition of MSW samples revealed that 80% of wastes were recyclable, 19% as compostable materials, while only 1% of the materials were a non-recyclable waste. More than 73% of the recyclable materials include paper and plastic warranting dire need of an effective solid waste management program. The highest value of FPW was recorded for the breakfast meal.

Originality/value
Most of the waste generated from the university campus was recyclable type that needs to be handled carefully to avoid its mixing with other types of the waste stream. Waste characterization is an important tool that helps in understanding the amount and pattern of waste generation. It can be used as a decision-making tool for implementing sustainable waste management programs for universities.

Published: February 2021

PurposeThe purpose of this paper is to critically examine the impact of a growth enhancement support scheme (GESS) on youth development in informal farm entrepreneurship in Nigeria. Its special focus is to investigate the impact of the GESS on rural youths’ adoption of new technologies needed to sustainably increase food security in Nigeria.Design/methodology/approachThis paper adopts a survey research technique, aimed at gathering information from a representative sample of the population, as it is essentially cross-sectional, describing and interpreting the current situation. A total of 800 rural youths were sampled across the six geopolitical zones of Nigeria.FindingsThe result from the use of a bivariate probit model indicates that the GESS has a significant impact on rural youths’ innovations in farming.Practical implicationsThis suggests that information and communication technology could provide new opportunities for making farming more interesting and enterprising for rural young people.Social implicationsIt implies that while old male and female farmers are less likely to adopt the new farming technologies needed to achieve Nigeria’s agricultural transformation agenda (ATA), a younger generation can help introduce new technologies, while also learning from traditional methods.Originality/valueThis research adds to the literature on informal farm entrepreneurship and rural communities’ debate in developing countries. It concludes that engaging youths in GESS should form the foundation of the ATA in Nigeria, which, in turn, would offer adequate combination of new and traditional solution to address the challenges of food insecurity in Sub-Saharan Africa.
Evaluation of students’ attitude toward distance learning during the pandemic (Covid-19): a case study of ELTE university
Authors: Ismaili Yassine 
Published: February 2021

PurposeCovid-19 has prompted higher institutions around the globe to relocate traditional classes to online classes. Eötvös Loránd University (ELTE) was no exception. It had already drawn up limited strategies regarding distance education, but those Web-based platforms were provided only to students with special needs. Due to the pandemic, all ELTE students were compelled to use online platforms that the university provided, such as Microsoft Teams and Zoom, to resume their studies. This study aims to evaluate the initial experience of students in using these new platforms. It also explores the effects distance learning has on students’ satisfaction and attitudes toward their education.Design/methodology/approachBy using a quantitative approach, students’ attitudes toward e-learning and their access to tech-platforms, use of those platforms and satisfaction with online courses are processed and analyzed via a statistical package for the social sciences.FindingsThe results of this study show that distance learning is still in the development stage, and although traditional classrooms appeared to be indispensable, the positive attitudes and willingness of the majority of students to engage in distance learning classes in the post-COVID19 pandemic indicate that there is an immense potential future for e-learning platforms in higher education institutions.Originality/valueThe distance learning approach has been the only way for institutions worldwide to resume studies during the pandemic of Covid-19. Students faced mixed feelings of perplexity, loneliness, uncertainty over what is going to happen with classes, exams, graduation and other significant activities impacting their study path; irrespective of their daily struggles with the hard accessibility to means of e-learning and personal potential health problems. This evaluation is considered as a roadmap for institutions to follow-up and to improve the organizational and educational shortcomings they met.
Impact of regulatory efficiency and market openness to social and financial efficiency: empirical evidence from microfinance institutions
Authors: Mohamad Anwar Nazratul Aina , Iqbal Hussain Hafezali , Kamarudin Fakarudin , Sufian Fadzlan , Zainal Nurazilah , Wong Che Mun 
Published: February 2021

Purpose
Microfinance institutions (MFIs) play a significant role in society to help low-income consumers that liaise with sustainable development goals. Therefore, the purpose of this paper is to examine the effects of two economic freedom components, namely, regulatory efficiency on business freedom and monetary freedom; and market openness on investment freedom and financial freedom. Their influence on the efficiency of MFIs in both social and financial ways is examined.

Design/methodology/approach
This study collected a total of 88 MFIs from Thailand and the Philippines for the years 2011 to 2017. The data envelopment analysis approach has been used to measure the MFIs’ efficiency level. Then, the ordinary least squares and generalised least square estimation methods serve to analyse the effects of economic freedom and other determinants on efficiency.

Findings
The results show that overall MFIs operate at an encouraging level. However, they were managerially inefficient when exploiting resources to achieve both social and financial efficiency. Therefore, MFIs should focus more on managerial operations to improve the level of efficiency. Results from panel regression analysis showed a mixed outcome for the relationship between economic freedom and MFIs’ efficiency both financially and socially. This suggested that different freedoms will result in different outcomes and significantly influence MFIs’ financial and social efficiency.

Originality/value
Regulatory efficiency and market openness are the vital aspects of economic freedom components that may significantly influence MFI’s performance specifically on social and financial efficiency. This study fills the research gap by examining the relationship between economic freedom components and specific MFIs’ social and financial efficiency, to ensure MFIs work to achieve sustainable development goals.

Published: February 2021

AbstractSurgical‐site infection (SSI) is one of the major postoperative complications in surgery, which can cause significant morbidity. However, factors associated with SSI in dermatological surgery are not well understood. Here, we retrospectively investigated 512 patients who underwent outpatient surgery for skin tumors at the University of Tsukuba Hospital to analyze factors associated with postoperative SSI. The overall incidence of SSI was 28 (5.5%). Univariate logistic regression analysis revealed that SSI was significantly associated with invasive squamous cell carcinoma (iSCC), Bowen’s disease (BD), actinic keratosis (AK), longer diameter of defects, presence of ulcer, reconstruction with full‐thickness skin graft and local skin flaps, medical history of diabetes mellitus, and use of immunosuppressive agents. However, in the multivariate analysis only iSCC, BD, and AK retained significance. The frequencies of SSI in iSCC, BD, and AK were 22% (13/58 patients), 15.6% (5/32), and 25% (2/8), respectively; however, the frequency of other non‐SCC tumors was only 1.9% (8/414). χ2‐Tests revealed that the frequency of SSI in iSCC, BD, and AK were all significantly higher than in non‐SCC tumors, with the frequencies being more than eight times higher. These results suggest that invasive and in situ lesions of SCC are independent risk factors of SSI development after outpatient skin surgery.
Role of the SphK‐S1P‐S1PRs pathway in invasion of the nervous system by SARS‐CoV‐2 infection
Authors: Pan Yuehai , Gao Fei , Zhao Shuai , Han Jinming , Chen Fan 
Published: February 2021

AbstractGlobal spread of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is still ongoing. Before an effective vaccine is available, the development of potential treatments for resultant coronavirus disease 2019 (COVID‐19) is crucial. One of the disease hallmarks is hyper‐inflammatory responses, which usually leads to a severe lung disease. Patients with COVID‐19 also frequently suffer from neurological symptoms such as acute diffuse encephalomyelitis, brain injury and psychiatric complications. The metabolic pathway of sphingosine‐1‐phosphate (S1P) is a dynamic regulator of various cell types and disease processes, including the nervous system. It has been demonstrated that S1P and its metabolic enzymes, regulating neuroinflammation and neurogenesis, exhibit important functions during viral infection. S1P receptor 1 (S1PR1) analogues including AAL‐R and RP‐002 inhibit pathophysiological responses at the early stage of H1N1 virus infection and then play a protective role. Fingolimod (FTY720) is an S1P receptor modulator and is being tested for treating COVID‐19. Our review provides an overview of SARS‐CoV‐2 infection and critical role of the SphK‐S1P‐SIPR pathway in invasion of SARS‐CoV‐2 infection, particularly in the central nervous system (CNS). This may help design therapeutic strategies based on the S1P‐mediated signal transduction, and the adjuvant therapeutic effects of S1P analogues to limit or prevent the interaction between the host and SARS‐CoV‐2, block the spread of the SARS‐CoV‐2, and consequently treat related complications in the CNS.
Evidence of repeated mirtazapine poisoning in children by hair analysis
Authors: Kintz Pascal , Raul Jean‐Sébastien , Ameline Alice 
Published: February 2021

AbstractMirtazapine is an antidepressant drug, used to treat depression, but also, in some specific conditions, to treat obsessive–compulsive disorder and anxiety. Although mirtazapine is not a hypnotic, it can make the subject feel drowsy. Children under the age of 18 should not take mirtazapine, but for some very special diseases, a physician can prescribe it for a limited period of time. The authors report a case involving 2 children (7‐ and 9‐year‐old) who were administered mirtazapine without consent by the mother, who was under daily therapy with this antidepressant. Hair specimens, collected from the children were tested by liquid chromatography coupled to tandem mass spectrometry for mirtazapine and its metabolite, N‐desmethylmirtazapine, on 3 × 1 cm segments. The hair test results (3 × 1 cm segments) have demonstrated that both children have been repetitively exposed to mirtazapine for approximately the last 3 months before hair collection, with concentrations in the range 1.32–3.79 and 0.64–2.54 ng/mg for mirtazapine and N‐desmethylmirtazapine, respectively. Environmental contamination was ruled out as the measured concentrations are highly variable according to the pattern of drug distribution and the washes were negative. Hair testing for drugs appears as an excellent diagnostic tool for child protection toward drug exposure.
