Authors: Mohite Shailaja Sanjay , Kolekar Uttam D. 
Published: May 2021

PurposeFemtocells are low-power, inexpensive base stations (BS) used in business enterprises or homes. They could offer higher SNR in a smaller coverage area to enhance the data rates and QoS. Deployment of femtocell is expected to the witness constant development in upcoming years. Despite of all these benefits, there are certain challenges to be resolved that includes management of overlaying MC, interference among femtocells and the resource allocation between 2 tiers.Design/methodology/approachThis work analyses the issues on cross-tier interfering and resource allocation alleviation in “full-duplex (FD) Orthogonal Frequency Division Multiple Access (OFDMA) oriented Heterogeneous Networks (HetNets) that includes macrocell as well as underlying femtocells”. This work concerns on three foremost contributions: portraying a single objective issue including subcarrier allocation, price allocation and power allocation of macrocell–femtocell networks. Moreover, this work introduces a novel Cat Swarm Mated-Lion algorithm (CSM-LA) for solving the defined optimization problem in macrocell–femtocell networks. At last, the supremacy of adopted scheme is proved over traditional models regarding statistical and convergence analysis.FindingsBy concerning the cost function, the developed CSM-LA attained 87.5, 60, 93.75 and 93.75% better than LM, WOA, LA and CSO respectively. For utility analysis, it accomplished 70.58% better than LM, 88.23% superior to GWO, 85.88% superior to WOA and 88.23% better than CSO. For statistical analysis, the median performance of developed CSM-LA attained better results, which was 80.52% superior to LA, 80.74% better than GWO, 72% superior to WOA and 48.7% better than LA. Hence, the developed CSM-LA proved its performance in terms of improved results and revealed its betterment over the conventional models.Originality/valueThis paper adopts a latest optimization algorithm called CSM-LA for analyzing the issues on cross-tier interfering and resource allocation alleviation in full-duplex (FD) orthogonal frequency division multiple access (OFDMA) oriented heterogeneous networks (HetNets). This is the first work that utilizes CSM-LA framework that proposes a new CSM-LA model for power control and resource allocation by considering the multi-objectives like price, subcarrier and power as well.
Dynamics between ownership structure and dividend policy: evidence from Bangladesh
Authors: Hasan Md. Bokhtiar , Wahid Abu N. M. , Amin Md. Ruhul , Hossain Md. Delowar 
Published: May 2021

PurposeThe purpose of this study is to examine the impact of ownership structure such as family, government, institutional, foreign and public on dividend payouts as a representative of dividend policy of nonfinancial firms in Bangladesh.Design/methodology/approachThis study employs a dynamic panel data model, namely, differenced generalized method of moments (GMM), which follows a two-step process. The study uses annual data of a sample of 159 nonfinancial firms of Dhaka Stock Exchange for the period 2008–2017, which constitutes a panel data of 1,590 firm-year observations.FindingsThis study’s findings reveal that family and public ownerships have a significant and positive effect on dividend payouts, while government and institutional ownerships have a significant but negative effect. This study additionally incorporates some very important controlled variables and finds that except for size, all the selected controlled variables, i.e. lagged-one of dividend payout, returns on assets, debts to assets, price-earnings (PE) ratio, age and financial crisis have a significant effect on the dividend payouts. However, the findings support several dividend-related theories or hypotheses, i.e. agency cost theory, dividend stability theory and reputation hypothesis.Research limitations/implicationsThis study could consider some other aspects of corporate governance, as well as other emerging markets and financial institutions to perceive whether the results differ. Also, investigation could be carried out on conventional and Islamic firms individually to observe if the findings are different. However, the researchers are suggested to incorporate these issues in their future studies.Practical implicationsThis study offers an important insight into the relationship dynamics between dividend payouts and ownership structure in the context of an emerging market like Bangladesh. Moreover, it enhances the understanding of the ties of dividend payouts with the firm-specific factors as well as the financial crisis. The findings of the present study have also important implications for managers, policymakers and researchers, who are in quest of directions on the dividend policy of publicly listed nonfinancial firms.Originality/valueMost of the previous studies consider one or two types of ownership to examine the impacts on dividend payouts, while this study uses five types of ownership accompanied by a different data set. Moreover, to the authors’ knowledge, no study in Bangladesh has yet addressed this issue in such a comprehensive manner as theirs.
Tribological performance evaluation on brake friction material by using multi-objective optimization methods
Authors: Öktem Hasan , Shinde Dinesh 
Published: May 2021

Purpose
The purpose of this study is to present a novel approach for the evaluation of tribological properties of brake friction materials (BFM).

Design/methodology/approach
In this study, a BFM was newly formulated with 16 different ingredients and produced using an industrial hot compression molding process. Experimentation was carried out on the brake tester, which was developed for this purpose according to SAE J661 standards. The braking applications, sliding speed and braking pressure were considered as performance parameters, whereas coefficient of friction (CoF) and wear rate as output parameters. The influence of the performance parameters on the output was studied using response surface plots. Analysis of variance and regression analysis was accomplished for post-experimental evaluation of results. Multi-criteria decision-making (MCDM) and multi-objective genetic algorithm (MOGA) were applied for estimating the most critical performance parameter combination to evaluate the BFM.

Findings
The present experimental model was significant and effectively used to predict the performance. MCDM generates the optimal values for the parameters braking applications, braking pressure (Bar) and sliding speed (rpm) as 1000, 30 and 915, whereas MOGA as 1008, 10.503 and 462.8202, respectively.

Originality/value
An efficient model for performance evaluation of the BFM considering maximum CoF and minimum wear rate was experimentally presented and statistically verified. Also, the two multi-objective optimization methodologies were implemented and compared. A comparison between the results of MCDM and MOGA reveals that MOGA yields 30% better results than MCDM.
Digital self-harm: an empirical analysis of the effects of broadband adoption on suicide
Authors: Kyung Nakyung , Lim Sanghee , Lee Byungtae 
Published: May 2021

PurposePast literature offered competing predictions of the effect of broadband Internet on suicide. The Internet facilitates suicide by providing suicide-related information and ruining mental health. In contrast, Internet prevents suicide by offering social interaction and online mental treatment. This study aims to solve this tension by empirically examining the effect of broadband Internet on suicide with large-scale panel set.Design/methodology/approachThis study takes instrument approach with the US county-level panel set for the period 2013–17. This study uses the number of household broadband Internet subscriptions as the measure of broadband and leverages the number of telecommunication carriers as an instrument to address concern for endogenous relationship.FindingsThere exists a positive and significant association between broadband Internet adoption and suicide on average. This study provides empirical evidence that this association is attributable to the Internet's role in leading to a general decline in the mental well-being and in providing suicide-relevant information. This association is more evident in areas with high poverty and low social capital.Originality/valueThis study contributes to literatures that address the dark side of information systems in general and that address how Internet adoption can influence public health and well-being in particular. Results of underlying mechanisms why Internet affects suicide, and heterogeneous effect of Internet by poverty and social capital provide insight for governments to enact proactive regulations to address continuing rise of suicide.
The necessity to activate long-term ETD in Korea
Authors: Lee Hyoseob 
Published: May 2021

Purpose
This paper aims to provide the necessity to activate long-term exchange-traded derivatives (ETD) in Korea. In the era of aging, low interest rates and low economic growth, the investment demand for long-term financial products, and its hedging demand have steadily increased. Unfortunately, long-term ETD do not trade in Korea, and this study presents political suggestions to invigorate long-term ETD based on overseas cases and empirical analysis. Specifically, this study suggests the necessity to activate exchange traded funds (ETFs) options, long-term Korea treasury bond futures and options and long-term Volatility Index of Korea Composite Stock Price Index future and options. The introduction of those long-term ETD not only contributes to providing long-term investment and hedging vehicles but also reduces market inefficiencies in the Korean industry of ETFs, bonds and structured products.
Understanding the impact of well-being on entrepreneurship in the context of emerging economies
Authors: Henao García Edwin Alexander , Galia Fabrice , Velez-Ocampo Juan 
Published: May 2021

Purpose
This paper aims to assess what happens to a willingness to take entrepreneurial action when people experience low or high subjective well-being (SWB) in 12 emerging economies.

Design/methodology/approach
The research uses principal component analysis (PCA) and logistic regressions with a data sample from the global entrepreneurship monitor (GEM) for emerging economies.

Findings
The main results suggest that SWB, measured as satisfaction with life (SWL) and job satisfaction (JOBS), increases the probability of a person becoming an entrepreneur.

Social implications
The findings of this research suggest that designing and implementing public policies that seek to promote the well-being of individuals might foster their entrepreneurial activities in emerging economies.

Originality/value
The literature on entrepreneurship, which assesses its relationship with SWB is still scarce. Most of the academic work has been carried out for developed countries, mainly analysing how entrepreneurial activity affects SWB in self-employees or entrepreneurs. This manuscript analyses these elements in the opposite direction, contributing to an underdeveloped discussion on how well-being affects the decision to be an entrepreneur.
Leveraging customer-to-customer interactions to create immersive and memorable theme park experiences
Authors: Wei Wei , Zheng Yanyan , Zhang Lu , Line Nathaniel 
Published: May 2021

PurposeTheme park experiences ubiquitously unfold in the presence of others. In acknowledgement of this important part of theme park consumption, this research set out to examine if other visitors help create an immersive environment and, in turn, memorable experiences for theme park visitors.Design/methodology/approachAn online survey was distributed to 561 theme park visitors. Structural equation modeling (AMOS 26) was used for testing the hypotheses in the proposed framework.FindingsResults of SEM analyses reveal the positive impact of perceived similarity on visitors' sense of immersion at theme parks and the memorability of the experience. In turn, memorable experiences further drive behavioral intentions (i.e., return intention and willingness to pay premiums).Practical implicationsThe findings provide suggestions for theme parks to leverage customer-to-customer interactions in order to create immersive and memorable visitor experiences.Originality/valueThis research marks one of the first attempts to approach customer-to-customer interactions (CCIs) at theme parks by empirically examining the impact of the perceived similarity of others on focal visitors' emotions and experiences.
An investigation of technology trust and habit in IT use continuance: a study of a social network
Authors: Ambalov Igor Alexander 
Published: May 2021

PurposeSocial networking services/systems (SNSs) have grown in popularity in the past decade. However, while some have been abandoned by their once loyal users, others have grown in popularity. Literature provides diverse and often conflicting justifications for this phenomenon. Seeking a credible explanation, this study aims to examine the roles of system-like trust and habit in SNS use continuance.Design/methodology/approachThis study conducted a comprehensive review of related literature to formulate an extended model of information technology (IT) continuance. A cross-sectional field survey was used to collect data from 401 university-student Facebook users. The research model was evaluated using structural equation modeling.FindingsThe results indicate that trust in technology and hedonic motivation are important direct influences on end-user continuance intention (CI), while habit is not. Interestingly, the most salient (indirect) predictor of CI is confirmation of (user) expectations.Practical implicationsThe study suggests a set of practical steps that managers and practitioners can undertake to support users’ decisions to continue using the systems.Originality/valueThis paper advances IT continuance research by theorizing that trust in technology along with habit and hedonic motivation positively influence CI. In addition, the study enhances the concept of perceived usefulness by modeling this unitary measure as a multidimensional construct.
“The contribution of MOOCs to upskilling the labor force”
Authors: Goglio Valentina , Bertolini Sonia 
Published: May 2021

Purpose
The study aims to investigate whether participation to massive open online courses (MOOCs) may lead to labor market returns and through which mechanisms such relative advantage may take place. Indeed, despite high figures of registered users, empirical studies on occupational returns are limited and MOOCs may represent a viable, cost-efficient example of lifelong learning practice to respond to the demand of a better skilled workforce for the fourth industrial revolution.

Design/methodology/approach
The study is based on qualitative empirical material constituted by a set of 21 qualitative semi-structured interviews conducted in 2019 among learners who registered in MOOCs provided by European higher education institutions.

Findings
Interviews return a situation in which MOOCs are beneficial for work: learners appreciate the new knowledge and skills they can access, with time flexibility and low entry cost. However, MOOCs positive contribution is not at everyone’s reach: self-selection issues tend to further advantage individuals with high levels of education and individual resources. Moreover, MOOCs can increase the risk of a shift of responsibility for training to the employees and qualify as a lower tier type of qualification, reinforcing social closure mechanisms based on educational credentials.

Originality/value
The study contributes to the empirical analysis of MOOCs economic returns empirically, by providing original qualitative material. Second, it contributes theoretically by bridging literature on economic and occupational returns to education on one side and literature on digital technologies in education on the other, providing new insights on the potentials and limits of MOOCs as a new form of lifelong learning.
Do Indian firms engage in classification shifting to report inflated core earnings?
Authors: Bansal Manish , Kumar Ashish , Badhani K. N. 
Published: May 2021

PurposeThe authors aim at investigating different forms of classification shifting (CS). CS is a novel form of earnings management under which managers misclassify income statement line items and cash flow statement line items with an intent to report favorable operating performance of firms. In particular, the authors check the existence of revenue misclassification, expense misclassification and cash flows misclassification among Indian firms by taking the uniform sample of firms over a single period.Design/methodology/approachOperating revenue model (Malikov et al., 2018), core earnings expectation model (McVay, 2006) and operating cash flows model (Roychowdhury, 2006) are employed for measuring revenue misclassification, expense misclassification and cash flows misclassification, respectively. The panel data regression models are used to analyze the data for this study.FindingsBased on the sample of 12,870 Bombay Stock Exchange (BSE) listed firm-years observations between 2010 and 2018, we find that, on average, Indian firms are engaged in revenue misclassification rather than expense misclassification to report inflated core earnings. Firms are found to be engaged in cash flows misclassification too. Besides, we find that magnitude of shifting is greater among larger firms. Results also establish that adoption of Ind AS increases the scope of shifting practices. These results are based on several robustness checks.Practical implicationsThe results suggest that investors conduct a comprehensive review of the items of financial statements before using them in their portfolio valuation. It suggests auditors check the basis of revenue classification and standard-setting authorities, like ICAI in India, to make more mandatory disclosure requirements for classification of revenues and cash flows. It suggests lenders not to make lending decisions by looking at the operating performance metrics, as CS is the most preferred tool to positively influence the perception of lenders toward operating performance.Originality/valueIt is the first study that investigates different forms of classification shifting jointly for a sample of firms. Most of the earlier studies have examined one kind of classification shifting at a time. This study adds to the existing literature on earnings management by documenting that some firm-specific factors pressurize firms to prefer one form of shifting over another to report inflated core earnings.
Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics
Authors: Nash Liam N. , Antiqueira Pablo A. P. , Romero Gustavo Q. , de Omena Paula M. , Kratina Pavel 
Published: May 2021

Abstract

Aquatic ecosystems are tightly linked to terrestrial ecosystems by exchanges of resources, which influence species interactions, community dynamics and functioning in both ecosystem types. However, our understanding of how this coupling responds to climate warming is restricted to temperate, boreal and arctic regions, with limited knowledge from tropical ecosystems.

We investigated how warming aquatic ecosystems impact cross‐ecosystem exchanges in the tropics, through the export of aquatic resources into the terrestrial environment and the breakdown of terrestrial resources within the aquatic environment. We experimentally heated 50 naturally assembled aquatic communities, contained within different‐sized tank‐bromeliads, to a 23.5–32°C gradient of mean water temperatures.

The biomass, abundance and richness of aquatic insects emerging into the terrestrial environment all declined with rising temperatures over a 45‐day experiment. Structural equation and linear mixed effects modelling suggested that these impacts were driven by deleterious effects of warming on insect development and survival, rather than being mediated by aquatic predation, nutrient availability or reduced body size. Decomposition was primarily driven by microbial activity. However, total decomposition by both microbes and macroinvertebrates increased with temperature in all but the largest ecosystems, where it decreased. Thus, warming decoupled aquatic and terrestrial ecosystems, by reducing the flux of aquatic resources to terrestrial ecosystems but variably enhancing or reducing terrestrial resource breakdown in aquatic ecosystems.

In contrast with increased emergence observed in warmed temperate ecosystems, future climate change is likely to reduce connectivity between tropical terrestrial and aquatic habitats, potentially impacting consumers in both ecosystem types. As tropical ectotherms live closer to their thermal tolerance limits compared to temperate species, warming can disrupt cross‐ecosystem dynamics in an interconnected tropical landscape and should be considered when investigating ecosystem‐level consequences of climate change.
