Biocompatibility characterisation of CMOS-based Lab-on-Chip electrochemical sensors for in vitro cancer cell culture applications
Authors: Beykou Melina , Bousgouni Vicky , Moser Nicolas , Georgiou Pantelis , Bakal Chris 
Published: November 2023

AbstractLab-on-Chip electrochemical sensors, such as Ion-Sensitive Field-Effect Transistors (ISFETs), are being developed for use in point-of-care diagnostics, such as pH detection of tumour microenvironments, due to their integration with standard Complementary Metal Oxide Semiconductor technology. With this approach, the passivation of the CMOS process is used as a sensing layer to minimise post-processing, and Silicon Nitride (Si3N4) is the most common material at the microchip surface. ISFETs have the potential to be used for cell-based assays however, there is a poor understanding of the biocompatibility of microchip surfaces. Here, we quantitatively evaluated cell adhesion, morphogenesis, proliferation and mechano-responsiveness of both normal and cancer cells cultured on a Si3N4, sensor surface. We demonstrate that both normal and cancer cell adhesion decreased on Si3N4. Activation of the mechano-responsive transcription regulators, YAP/TAZ, are significantly decreased in cancer cells on Si3N4in comparison to standard cell culture plastic, whilst proliferation marker, Ki67, expression markedly increased. Non-tumorigenic cells on chip showed less sensitivity to culture on Si3N4than cancer cells. Treatment with extracellular matrix components increased cell adhesion in normal and cancer cell cultures, surpassing the adhesiveness of plastic alone. Moreover, poly-l-ornithine and laminin treatment restored YAP/TAZ levels in both non-tumorigenic and cancer cells to levels comparable to those observed on plastic. Thus, engineering the electrochemical sensor surface with treatments will provide a more physiologically relevant environment for future cell-based assay development on chip.
Stochastic redesign of mini UAV wing for maximizing autonomous flight performance
Authors: Çoban Sezer 
Published: November 2023

Purpose
The purpose of this research paper is to recover the autonomous flight performance of a mini unmanned aerial vehicle (UAV) via stochastically optimizing the wing over certain parameters (i.e. wing taper ratio and wing aspect ratio) while there are lower and upper constraints on these redesign parameters.

Design/methodology/approach
A mini UAV is produced in the Iskenderun Technical University (ISTE) Unmanned Aerial Vehicle Laboratory. Its complete wing can vary passively before the flight with respect to the result of the stochastic redesign of the wing while maximizing autonomous flight performance. Flight control system (FCS) parameters (i.e. gains of longitudinal and lateral proportional-integral-derivative controllers) and wing redesign parameters mentioned before are simultaneously designed to maximize autonomous flight performance index using a certain stochastic optimization strategy named as simultaneous perturbation stochastic approximation (SPSA). Found results are used while composing UAV flight simulations.

Findings
Using stochastic redesign of mini UAV and simultaneously designing mini ISTE UAV over previously mentioned wing parameters and FCS, it obtained a maximum UAV autonomous flight performance.

Research limitations/implications
Permission of the directorate general of civil aviation in the Republic of Türkiye is essential for real-time UAV autonomous flights.

Practical implications
Stochastic redesign of mini UAV and simultaneously designing mini ISTE UAV wing parameters and FCS approach is very useful for improving any mini UAV autonomous flight performance cost index.

Social implications
Stochastic redesign of mini UAV and simultaneously designing mini ISTE UAV wing parameters and FCS approach succeeds confidence, highly improved autonomous flight performance cost index and easy service demands of mini UAV operators.

Originality/value
Creating a new approach to recover autonomous flight performance cost index (e.g. satisfying less settling time and less rise time, less overshoot during flight trajectory tracking) of a mini UAV and composing a novel procedure performing simultaneous mini UAV having passively morphing wing over certain parameters while there are upper and lower constraints and FCS design idea.
Predicting stock market crashes on the African stock markets: evidence from log-periodic power law model
Authors: Ben Yaala Sirine , Henchiri Jamel Eddine 
Published: November 2023

PurposeThis study aims to predict stock market crashes identified by the CMAX approach (current index level relative to historical maximum) during periods of global and local events, namely the subprime crisis of 2008, the political and social instability of 2011 and the COVID-19 pandemic.Design/methodology/approachOver the period 2004–2020, a log-periodic power law model (LPPL) has been employed which describes the price dynamics preceding the beginning dates of the crisis. In order to adjust the LPPL model, the Global Search algorithm was developed using the “fmincon” function.FindingsBy minimizing the sum of square errors between the observed logarithmic indices and the LPPL predicted values, the authors find that the estimated parameters satisfy all the constraints imposed in the literature. Moreover, the adjustment line of the LPPL models to the logarithms of the indices closely corresponds to the observed trend of the logarithms of the indices, which was overall bullish before the crashes. The most predicted dates correspond to the start dates of the stock market crashes identified by the CMAX approach. Therefore, the forecasted stock market crashes are the results of the bursting of speculative bubbles and, consequently, of the price deviation from their fundamental values.Practical implicationsThe adoption of the LPPL model might be very beneficial for financial market participants in reducing their financial crash risk exposure and managing their equity portfolio risk.Originality/valueThis study differs from previous research in several ways. First of all, to the best of the authors' knowledge, the authors' paper is among the first to show stock market crises detection and prediction, specifically in African countries, since they generate recessionary economic and social dynamics on a large extent and on multiple regional and global scales. Second, in this manuscript, the authors employ the LPPL model, which can expect the most probable day of the beginning of the crash by analyzing excessive stock price volatility.
Effect of place attachment on consumers' place preference and repatronage intention toward coffee shops
Authors: Wang Shih-Tse Edward , Lin Hung-Chou , Lee Yi-Ting 
Published: November 2023

PurposeBecause of the slow market growth of and intense competition among coffee shops, increasing brand preference and patronage intention is crucial in the coffee shop industry. Although place attachment theory (PAT) and social identity theory (SIT) stipulate that place attachment and social identity are key constructs of revisit intention, no studies have yet integrated the dimensions of SIT into PAT to predict place preference (PP) and repatronage intention (RI). In this study, the authors aimed to develop a theoretical model grounded in PAT and SIT to predict PP and RI.Design/methodology/approachA total of 648 coffee shop customers participated in an online survey, and their data were analyzed through structural equation modeling.FindingsThe results indicated that cognitive and affective place identity (PI) directly affected place dependence (PD) but did not directly affect PP. Cognitive PI also indirectly affected PD through affective PI. PD exerted a positive and significant effect on PP and thus affected RI.Originality/valueThese findings provide insights into the importance of cognitive and affective PI in shaping PD, PP and RI. From a place attachment perspective, the theoretical model enables coffee shop managers to cultivate strong PP to increase customer RI.

Authors: Kumar Poonam , Chauhan Sumedha , Kumar Satish , Gupta Prashant 
Published: November 2023

PurposeIn mobile banking (m-banking), understanding the factors contributing to customer satisfaction is crucial for bank managers to design effective strategies for enhancing the uptake of mobile banking services. This study assesses the relationships between quality, technology acceptance and credibility factors and behavioural outcomes (actual use, continuance intention and loyalty) and satisfaction with m-banking. It further investigates the moderating influence of economy type, innovation level, connectivity level and sample size on all these relationships.Design/methodology/approachThe study employs a meta-analysis technique and reviews 54 published studies to investigate the antecedents and consequences of satisfaction with m-banking.FindingsThe study finds a significant relationship between satisfaction with m-banking and quality, technology acceptance and credibility factors and behavioural outcomes. It concludes that the moderating effect of economy type, innovation level, connectivity level and sample size partially moderate the majority of the hypothesized relationships.Research limitations/implicationsDrawing on a comprehensive literature review, this study presents a novel framework elucidating the antecedents and behavioural outcomes of satisfaction with mobile banking. It contributes to the literature by exploring the moderating effects of sample size and country context on the relationships between these factors, presenting important implications for future mobile banking research.Practical implicationsThis study has practical implications for m-banking service providers, offering insights into the factors that drive user satisfaction with mobile banking and highlighting the need for tailored strategies in different country contexts.Originality/valueThis study examines the effects of factors leading to satisfaction and the subsequent outcomes within the context of m-banking. The findings offer fresh perspectives that can be valuable for managers and policymakers, enabling them to enhance customer satisfaction in the realm of m-banking.
Free apps and paid apps: monetization strategies for health apps in the Portuguese market
Authors: Lemos Natália , Machado Cândida Sofia , Cardoso Cláudia 
Published: November 2023

PurposeThe rapid advancement of technology has transformed the health-care industry and enabled the emergence of m-Health solutions such as health apps. The viability and success of these apps depends on the definition of a monetization model appropriate to their specificities. In this sense, the purpose of this paper is to study the mechanisms of monetization of health apps, to stablish how alternative revenues determine if a health app is to be free or paid.Design/methodology/approachProbability models are used to identify the factors that explain if a health app is free or paid.FindingsResults show that the presence of alternative monetization mechanisms negatively impacts the likelihood of a health app being paid for. The use of personal data to customize advertising (the monetization of “privacy capital”) or the inclusion of ads on the app are alternative means of monetization with potential to decrease the likelihood of a health app being paid for. The possibility of in-app purchases has a lower negative impact on the probability of a health app being paid for. The choice of platform to commercialize an app is also a strategic decision that influences the likelihood of an app being paid for.Originality/valueThis work stands out for bringing together the two largest platforms present in Portugal and for focusing on the perspective of revenue and monetization of health apps and not on the perspective of downloads.

Published: November 2023

PurposeThis scholarly investigation explores the Malaysian golfers' experience in Malaysia, Thailand and Indonesia golf courses. The study sheds light on the unique attributes of golf tourism in each country, including the courses, facilities, services and overall golfing experiences offered to golf tourists.Design/methodology/approachQualitative data were procured through in-depth semi-structured interviews with a cohort of 13 Malaysian golfers.FindingsThe findings indicate that golfers' experiences are affected by the quality of service, facilities, price and course condition, ultimately contributing to their satisfaction level. The evidence suggests that Malaysian golfers are comparatively more satisfied with golf courses in Thailand and Indonesia than in Malaysia.Originality/valueThe study underscores the importance of golf course attributes in retaining existing golfers and enticing new ones. Besides, as comparative research on golf course attributes and destination preferences is scant, this study has far-reaching implications, empowering Malaysian golf course managers to augment the appeal and quality of their golf course destination to optimise the behavioural intentions of golf tourists.
Regulating informal housing for the Syrian reconstruction. Between urban renewal and upgrading
Authors: Porras-Gómez Antonio-Martín 
Published: November 2023

Purpose
Informal housing stands out as a major challenge surrounding the massive reconstruction of Syrian cities, devastated by a bloody war and a terrible earthquake. The purpose of this article is to assess the adequacy of the Syrian Law to adequate provide a solution to this problem.

Design/methodology/approach
With the purpose of informing the question, this paper offers a legal-institutional analysis of the informal housing phenomenon and the corresponding regulatory responses in Syria. A literature review is conducted, and functional analysis of the legal texts and their effective implementation is provided.

Findings
First, informal housing in Syria has been fostered by the existence of an erratic regulation, particularly burdened by the incoherence of passing repressive provisions against informal housing while master plans were conspicuously absent or incomplete. Second, the regulatory policy seems to be leaning toward the urban renewal option, indicating a supply-oriented housing approach that may face serious challenges due to the scarcity of capital. In this context, regulation should not underestimate any policy tools at hand (renewal and upgrading; with the contribution of public, private and cooperative sectors).

Originality/value
Although there have been several studies on informal housing in Syria, none has taken a legal institutionalist approach. Furthermore, this study offers an up-to-date account of the problem, taking into account the problematic after the 2023 earthquake and the content of Law 2/2023.
Sustainability control systems in short-term operational and long-term strategic decision-making
Authors: Kuruppu Sanjaya C. , Milne Markus J. , Tilt Carol A. 
Published: November 2023

Purpose
This study aims to respond to calls for more research to understand how sustainability control systems (SCSs) feature (or do not feature) in short-term operational and long-term strategic decision-making.

Design/methodology/approach
An in-depth case study of a large multinational organisation undertaking several rounds of sustainability reporting is presented. Data collection was extensive including 26 semi-structured interviews with a range of employees from senior management to facility employees, access to confidential reports and internal documents and attendance of company meetings, including an external stakeholder engagement meeting and the attendance of the company’s annual environmental meeting. A descriptive, analytical and explanatory analysis is performed on the case context (Pfister et al., 2022).

Findings
Simon’s (1995) levers of control framework structures our discussion. The case company has sophisticated and formalised diagnostic controls and strong belief and boundary systems. Conventional management controls and SCSs are used in short-term operational decision-making, although differences between financial imperatives and other aspects such as environmental concerns are difficult to reconcile. SCSs also provided information to justify company actions in short-term decisions that impacted stakeholders. However, SCSs played a very limited role in the long-term strategic decision. Tensions between social, environmental and economic factors are more reconcilable in the long-term strategic decision, where holistic risks and opportunities need to be fully identified. External reporting is seen in a “constraining” light (Tessier and Otley, 2012), and intentionally de-coupled from SCSs.

Originality/value
This paper responds to recent calls for rich, holistic and contextually-grounded perspectives of sustainability processes at an extractives company. The study provides novel insight into how SCSs are used (or not used) in short-term or long-term decision-making and external reporting. The paper illustrates how a large company is responding to sustainability pressures within the unique contextual setting of New Zealand. The study outlines the imitations of existing practice and provides implications for how sustainability-based internal controls can be better embedded into organisations.
Early adopters of institutional creativity in integrated reporting
Authors: Agarwal Ruchi , Atif Muhammad 
Published: November 2023

Purpose
In the last two decades, risk reporting has followed a normative and calculative culture rather than the “materiality” of data. Although integrated reporting (IR) has become flooded with extra information, it does not adequately disseminate material information to stakeholders. In addition, the poor tone from the top diminishes creativity. This study aims to investigate how companies creatively address issues of the materiality of risk information in IR and how IR can be aligned with enterprise risk management.

Design/methodology/approach
Qualitative research was conducted via interviews with 50 chief risk officers and senior management executives in the Indian and UK insurance markets.

Findings
Overall, five institutions were observed to exhibit elements of being early adopters of institutional creativity. This confirmed the present study’s theoretical contribution of five divergent types of early adopters. The motivations for creativity are reflected in the resources available to these institutions.

Originality/value
To the best of the authors’ knowledge, this study provides a new insight into IR from internal mechanisms to deal with issue of materiality.
Effect on properties of geopolymer concrete by inclusion of recycled aggregate and methods to enhance the packing density of aggregate
Authors: Gupta Tanuja , Chakradhara Rao M. 
Published: November 2023

Purpose
This study aims to practically determine the optimum proportion of aggregates to attain the desired strength of geopolymer concrete (GPC) and then compare the results using established analytical particle packing methods. The investigation further aims to assess the influence of various amounts of recycled aggregate (RA) on properties of low-calcium fly ash-based GPC of grade M25.

Design/methodology/approach
Fine and coarse aggregates were blended in various proportions and the proportion yielding maximum packing density was selected as the optimum proportion and they were compared with analytical models, such as Modified Toufar Model (MTM) and J. D. Dewar Model. RAs for this study were produced in laboratory and they were used in various amounts, namely, 0%, 50% and 100%. 12M NaOH solution was mixed with Na2SiO3 in the ratio of 1:2. The curing of concrete was done at the temperatures of 60° and 90 °C for 24, 48 and 72h.

Findings
The experimentally obtained optimum proportion of coarse to fine aggregate was 60:40 for all amounts of RA. Meanwhile, MTM and Dewar Model resulted in coarse aggregate to fine aggregates as 40:60, 45:55, 55:45 and 55:45, 35:65, 60:40, respectively, for 0% 100% and 50% RAs. The compressive strength of GPC elevated with the increase in curing regime. In addition, the ultrasonic pulse velocity also displayed a similar trend as that of strength.

Originality/value
The GPC with 50% RAs may be considered for use, as it exhibited superior properties compared to GPC with 100% RAs and was comparable to GPC with natural aggregates. Furthermore, compressive strength is correlated with split tensile strength and ultrasonic pulse velocity.
Circ_0020123 promotes non‐small cell lung cancer progression via miR‐146a‐5p mediated regulation of EIF4G2 expression
Authors: Wei Zichun , Liu Jixian , Hui Gang , Luan Xinyu 
Published: November 2023

AbstractBackgroundCircular RNAs (circRNAs) have been reported to be involved in the initiation and development of cancers. The aim of this study was to determine the role of a circRNA, circ_0020123, in the development of non‐small cell lung cancer (NSCLC).MethodsThe expression of circ_0020123, microRNA‐146a‐5p (miR‐146a‐5p), and eukaryotic translation initiation factor 4 gamma 2 (EIF4G2) mRNA was detected by quantitative real‐time PCR (qPCR). Western blot was used to determine the protein levels of cyclin D1, Bax, MMP‐9, and EIF4G2. Cell proliferation was assessed by cell counting kit‐8 (CCK‐8) assay and colony formation assay. Flow cytometry assay was applied to determine cell cycle apoptosis. Cell migration and invasion were assessed using transwell assay. The potential relationship between miR‐146a‐5p and circ_0020123 or EIF4G2 was ascertained by dual‐luciferase reporter assay and RIP assay. The role of circ_0020123 in vivo was explored by xenograft assay.ResultsCirc_0020123 was upregulated in NSCLC, and circ_0020123 knockdown repressed proliferation, migration, and invasion of NSCLC cells. Circ_0020123 targeted miR‐146a‐5p, and miR‐146a‐5p inhibitor reversed the effects of circ_0020123 knockdown on NSCLC cells. In addition, miR‐146a‐5p suppressed cell proliferation, migration, and invasion by targeting EIF4G2. Moreover, the antitumor role of circ_0020123 knockdown was verified in vivo.ConclusionKnockdown of circ_0020123 inhibited NSCLC cell progression and tumor growth by targeting the miR‐146a‐5p/EIF4G2 axis.
