Reducing e-waste in China's mobile electronics industry: the application of the innovative circular business models
Authors: Marke Alastair , Chan Carmen , Taskin Gozde , Hacking Theo 
Published: July 2020

PurposeThe objectives of this research are to (1) fill the evidence gap of circular business activities and (2) enrich the knowledge base about the drivers of and barriers to circular economy business model (CEBM) that supports e-waste reduction in China’s mobile electronics industry. To answer the overarching research question of whether there are CEBMs emerging to address e-waste in China’ mobile electronics industry, we in this paper divided it into three sub-questions: (1) What CEBMs can support e-waste reduction? (2) Is there evidence for their implementation in China? and (3) What are the drivers of and barriers to these business model innovations?Design/methodology/approachWe started with setting the scene on the importance of better e-waste management and the scale of e-waste problem in China. Building on the oft-quoted ReSOLVE framework, developed by EMF (2015) and consolidated in Lewandowski (2016), we have refined from it 11 CEBMs to suit the context of e-waste reduction. These 11 models include regenerate, life cycle extension, take-back services, product sharing systems, optimise resource value, produce on demand, circular supplies, resource recovery, industrial symbiosis, product-as-a-service and transformative innovation. We have mapped these refined models against the evidence of circular business practices identified in the corporate sustainability reports of eight out of top 12 mobile electronics manufacturers in China.FindingsOur research findings show that six out of these 11 CEBMs are de facto practised in many of these companies. They include life cycle extension, collection services, optimise resource value, circular supplies, resource recovery and industrial symbiosis, although circular economy is still early-stage endeavours in the industry. As confirmed in our expert and company interviews, CEBM stems largely from profit and policy drivers. The key to building successful CEBMs to eliminate e-waste is, indeed, multi-stakeholder collaboration across the mobile electronics industry, which involves effective collection, reuse and recycling systems.Originality/valueThe lessons learnt can promote peer learning among EEE manufacturers and inform policymakers of effective strategies to create an enabling environment in which circular economy models can thrive.
Finance, corporate value and credit market freedom in overinvesting US firms
Authors: Iona Alfonsina , De Benedetto Marco Alberto , Assefa Dawit Zerihun , Limosani Michele 
Published: July 2020

Purpose
Using a sample of US firms more likely to be affected by agency problems, the purpose of this paper is to investigate the relationship between corporate value and financial policies and to study whether credit market freedom (CMF) affects this relationship.

Design/methodology/approach
The authors identify a sub-sample of non-financial US firms potentially affected by agency problems using a joint criterion of over-investment and high cash-holdings. A generalized method of moment econometric framework is then used to estimate the impact of cash-holdings and leverage policies on firm value for this sub-sample. This exercise is also performed by taking into account the level of CMF of the state where the firm operates.

Findings
The results show that the relationship between cash-holdings – or leverage – and firm value is “U-shaped.” In addition, when the authors focus on the role played by the level of CMF, the authors find a number of interesting facts: CMF facilitates the firms’ access to external finance, thereby relaxing the need of internal funds for investing; the relationship between cash-holdings and firm value is “U-shaped” only in states enjoying high levels of CMF; the probability of observing firms more likely to be affected by agency problems is higher in states with high levels of CMF.

Research limitations/implications
The empirical findings provide important insights to policymakers, shareholders and practitioners. To policymakers, the results suggest that providing institutional environments with greater CMF can enhance the firm access to external finance, the level of corporate investment and the economic growth. To shareholders, the findings highlight that the conflicts of interest between managers and shareholders may be more severe in states with higher CMF; therefore, adequate financing policies and corporate governance mechanisms must be used to mitigate these conflicts and maximize the firm value. Finally, to practitioners, the evidence suggests that, in valuing a firm, they must take into consideration whether the economic environment provides managers with more freedom to stockpile cash and invest sub-optimally.

Originality/value
The paper contributes to the corporate finance and governance literature in two respects. First, it provides new evidence on the shape of the relationship between cash holdings and firm value for firms affected by empire-building managers. Second, at the best of the knowledge, it is the first corporate finance study, which analyzes the role played by the CMF at the state level on the capital structure and the level of investment of the firms.
Switching harmonic suppression design based on multi-objective optimization algorithm with constraint processing
Authors: Huang Songtao , Ye Jie , Wang Haozhe , Li Baojin , Shen Anwen , Deng Junli 
Published: July 2020

Purpose
Traditional switching harmonic suppressor design methods require domain experts to adjust design parameters due to various complex performance requirements and practical limitations in switching ripple suppressor designs. The purpose of this paper is to present a method for filter parameter design.

Design/methodology/approach
An improved non-dominated sorting genetic algorithm II (NSGA II) was used in the inductor-capacitor-inductor (LCL) filter design to find the optimal design parameters, and a method was proposed to handle the constraints by transforming the them into decision variables.

Findings
The performance of the proposed algorithm in parameter designing was verified by simulation on MATLAB and experimental results on hardware-in-the-loop plat-form with StarSim software. The results indicate that the optimization algorithm has a better effect than the traditional expert parameters on each optimization index, especially on the switching harmonic suppression.

Originality/value
The paper presents an improved multi-objective optimization algorithm with ingenious constraints handing to obtain better filter parameters and reduces switching harmonics.
A secure communication approach in OFDM using optimized interesting region-based video watermarking
Authors: Wagdarikar Amir M.U. , Senapati Ranjan K. 
Published: July 2020

Purpose
The technique for hiding confidential data in specific digital media by enhancing the graphical contents is known as watermarking. The dissemination of information over a secure channel is essential for multimedia applications. The purpose of this study is to develop a secure communication approach for OFDM system.

Design/methodology/approach
This paper exploits a secure communication in the orthogonal frequency division multiplexing (OFDM) system using wavelet-based video watermarking technique. In this work, the Chronological-MS algorithm is used for securing the data communication in the OFDM system. Here, the secret message is embedded in video frames using wavelet transform for hiding sensitive information and the hidden information is transmitted over the OFDM system. The Chronological-MS algorithm is used for selecting the optimal regions in the video for embedding secret message. In embedding phase, wavelet coefficients are obtained by applying wavelet transform on the frame for embedding the secret message. Meanwhile, in extraction phase, the inverse wavelet transform is applied to extract the secret message.

Findings
Considering number of frames, the maximum Peak signal-to-noise ratio (PSNR) value is attained by proposed Wavelet + Chronological MS method for Video 2 with value 73.643 dB, respectively. Meanwhile, the minimum mean squared error (MSE) attained by the proposed Wavelet + Chronological MS method is when considering number of frames with MSE values as 0.001 for both Videos 1 and 2. The minimum bit error rate (BER) value is attained by the proposed method with value 0.00009 considering random noise with Video 1. Thus, the proposed Wavelet + Chronological MS have shown better results than the existing techniques.

Originality/value
This work proposes a wavelet-based watermarking method using Chronological-MS, for initiating secured communication over an OFDM. One of the main advantages of wavelets is that they offer a simultaneous localization in time and frequency domain. Hence, the proposed method offers the highly secured data transmission over the OFDM.
Tracking the Covid zones through geo-fencing technique
Authors: R. Anto Arockia Rosaline , R. Lalitha , G. Hariharan , N. Lokesh 
Published: July 2020

Purpose
Because of the outbreak of Covid 19, the entire world is thinking of new strategies, preventive measures to safeguard the human life from the widespread of the pandemic. The areas where people are affected are marked as containment zones and people are not allowed to exit out of those areas. Similarly, new people are not allowed to enter inside those areas. Hence, the purpose of this paper is to propose a methodology to track the Covid zones, to enhance and tighten the security measures. A geo-fence is created for the containment zone. The person who enters or exits out of that particular zone will be monitored and alert message will be sent to that person’s mobile.

Design/methodology/approach
After tracking the location of a suspicious individual, the geo-fenced layer is mapped in the area and then the virtual perimeter is used for further trapping process. This geo-fenced layer can be viewed by the citizens as soon as it is updated by the Covid monitoring team. The geo-fencing is a concept of building a virtual perimeter area. This virtual perimeter monitoring system helps in monitoring the containment zones effectively. It reduces operational costs by using an automated system based on wireless infrastructure. It also alerts the authorities immediately to catch the violators. Thus, it helps to speed up the process of inspecting the containment zones and monitoring the individuals who violate the rules given by government.

Findings
The proposed methodologies will be an effective way to track the Covid’s communal spread. But the workflow of the system demands the required data sets and permission in legal manner to set up the environment that maintains the constitutional law and order in practice. The application developed was a prototype to display how it works if the required data sets are provided by the government. There are several tracking models that are released across the world such as Aarogya setu (India), Trace together (Singapore) and Hagmen (Israel). All these models are based on Bluetooth proximity identification; though Bluetooth proximity identification is helpful for high range in a short distance, the privacy concern is debatable one. Using modern technology, it is so easy to crack the individual gadgets and with Bluetooth enabling it makes things even worse. Thus, it is important to maintain the tracking a safer and secure one, and another issue with those Bluetooth-based applications is that tracking can be done only if the user enabled the Bluetooth option, if not the entire functioning would become a mess. The proposed methodology of tracking without Bluetooth will ensure data security also.

Originality/value
This was developed as a project by our third-year students of the Department of Information Technology of our college.
Case study design for short-term predictable disasters
Authors: Grass Emilia , Fischer Kathrin 
Published: July 2020

PurposeThe purpose of this work is the development of a structured case study design process for developing case studies in humanitarian logistics, in particular for short-term predictable disaster situations like floods and hurricanes. Moreover, useful public sources are presented in order to enable researchers to find relevant data for their case studies more easily.Design/methodology/approachA structured framework for case study design is set up, splitting the process into different steps and phases.FindingsThe framework is applied to an illustrative example, where case studies with different numbers and levels of detail of scenarios are designed based on the three-day forecast for hurricane Harvey in 2017. The corresponding solutions demonstrate the relevance of using as much forecast information as possible in case study building, and in particular in scenario design, in order to get useful and appropriate results.Research limitations/implicationsThe case study design process is mostly suitable for short-term predictable disasters, but can also be adapted to other types of disasters. The process has been applied to one specific hurricane here which serves as an example.Practical implicationsAlso for practitioners, the results of this work are highly relevant, as constructing realistic cases using real data will lead to more useful results. Moreover, it is taken into account in the case study design process that relief agencies are regularly confronted with disasters in certain areas and hence need to define the basic planning situation and parameters “once and for all” and on a long-term basis, whereas disaster specific data from forecasts are only available within a short time frame.Originality/valueThe new design process can be applied by researchers as well as practitioners, and the publicly available data sources will be useful to the community.
The performative practices of consultants in a change network: an actor–network practice perspective on organisational change
Authors: Caldwell Raymond , Dyer Coral 
Published: July 2020

PurposeThis article positions actor–-network theory (ANT) as a practice perspective and deploys it to explore the performative practices of internal consultancy teams as they implemented major programmatic change projects within a global telecommunication company. The change process required the creation of a “change network” that emerged as a boundary spanning and organising network as the consultants sought to implement and translate a highly structured change methodology and introduce new meta-routines within the organisation.Design/methodology/approachBy combining the methodological datum of ANT to “follow the actors” (whatever form they take) with the guiding principle of practice theory to focus on practices rather than practitioners, the research explored the in-between temporal spaces of performative practices as they unfolded in relation to standardised routines, material artefacts and the tools and techniques of a systematic change methodology. By a method of “zooming out” and “zooming in” the research examined both the larger context of action and practice in which the change network emerged and the consultants' performative practices; but without falling into static macro–micro dualism, or a purely ethnographic “thick description” of practice. The research is based on interviews (25), participant observation and a review of the extensive documentation of the change methodology.FindingsThe findings indicate both how consultants' performative practices are embedded in the social and material arrangements of a change network, and why the intentional, expert or routine enactment of a highly standardised change methodology into practice is intrinsically problematic. Ultimately, the consultants could not rely on knowledge as a fixed, routine or pre-given empirical entity that predefined their actions. Instead, the consultants' performative practices unfolded in temporal spaces of in-betweenness as their actions and practices navigated shifting and multiple boundaries while confronting disparate and often irreconcilable ideas, choices and competing interests.Research limitations/implicationsAs an ANT practice perspective, the research blends mixed methods in an illustrative case study, so its findings are contextual, although the methodological rationale may be applicable to other contexts of practice.Originality/valueThe theoretical framing of the research contributes to repositioning ANT as practice theory perspective on change with a central focus on performative practice. The illustrative case demonstrates how a boundary spanning “change network” emerged and how it partly defined the temporal spaces of in-betweenness in which the consultants operated.
An exploration of motives and behavior across Facebook and Twitter
Authors: Spiliotopoulos Tasos , Oakley Ian 
Published: July 2020

Purpose
The purpose of this paper is to elaborate on how people navigate the social media ecosystem and how they decide, which social network site (SNS) to use. To this end, the current study draws from uses and gratifications (U&G) theory to elicit and compare motives for the use of Facebook and Twitter and uses behavioral data to examine the findings in the context of technology non-use.

Design/methodology/approach
An online survey was administered to 232 Facebook users and the results were complemented with 12 usage variables collected via the Facebook application programing interface for the same users. Exploratory factor analysis identified and described the motives for using Facebook and Twitter and multiple regression models examined the relationships between the motives for using the two sites. A multivariate analysis of variance and a series of t-tests investigated the differences in actual behavior between Twitter users and non-users.

Findings
Results suggest that SNS users will use both sites to gratify their need for information, but will only do so for entertainment that has social characteristics. Furthermore, Facebook users that are more embedded in the site and use the site to support their offline life are more likely to also use Twitter.

Practical implications
The paper includes implications for SNS researchers, designers and managers by highlighting the motivational and behavioral differences between users of the two sites and the importance of technological affordances for understanding and explaining SNS selection.

Originality/value
This study extends previous cross-site U&G and non-use research by combining survey and behavioral data.
Early intervention systems for police: a state-of-the-art review
Authors: Gullion Christi L. , King William R. 
Published: July 2020

PurposeThe purpose of this paper is to provide a comprehensive literature review of prior empirical studies that have examined early intervention (EI) systems or programs in policing.Design/methodology/approachA systematic literature search of various government and academic databases (e.g. Emerald, Google Scholar, National Criminal Justice Reference Service (NCJRS), Sage, Taylor & Francis and Wiley) was conducted.FindingsThis systematic review identified eight EI studies that matched the selection criteria. Of these, two are multiagency studies and six are individual agency studies. Findings across studies are generally positive but overall relatively inconsistent with regard to EI systems' effectiveness.Practical implicationsPolice agencies benefit in identifying and addressing at-risk officers to ensure police accountability and officer safety, health and wellness. This research is invaluable for optimizing how EI systems can use agency data for such predictions.Originality/valueThis state-of-the-art review on EI systems in policing is the first of its kind. EI systems have been implemented by many police agencies, yet a limited number of empirical studies have been conducted. This systematic review will be useful for researchers who wish to further explore how EI systems are utilized and whether EI systems are successful/effective.
Flexible working and applicant attraction: a person–job fit approach
Authors: Stich Jean-François 
Published: July 2020

PurposeThe ability to work anytime from anywhere is attractive to job seekers, who respond by developing needs regarding flexible working. Flexibility needs are compared to the flexibility perceived in job advertisements to form an overall perception of flexibility fit. The purpose of this paper is to examine both the impact of flexibility fit (on applicant attraction) and its antecedents.Design/methodology/approachThe impact of flexibility fit on applicant attraction and its antecedents are examined using person–job (PJ) fit theory. 92 job seekers analyzed a total of 391 job advertisements. The hypotheses are tested using multilevel structural equation modeling.FindingsThe results show that perceived flexibility fit is positively related to job pursuit and job acceptance intentions. They further show that perceived flexibility fit is driven by perceived job advertisements' flexibility exceeding applicants' needed flexibility, which in turn is driven by the flexibility actually present in job advertisements exceeding applicants' flexibility needs.Originality/valueThis study contributes to literature on new ways of working by highlighting the desirable nature of flexibility and its impact on fit perceptions. It further contributes to literature on job search and PJ fit by investigating a full model of fit, examining both outcomes and antecedents of perceived fit. For practitioners, this study highlights the importance of advertising flexibility to attract applicants.
Top management team international experience, international information acquisition and international strategic decision rationality
Authors: Azam Akbar , Bertolotti Fabiola , Boari Cristina , Atif Mian Muhammad 
Published: July 2020

PurposeThe purpose of this paper is to test whether Top Management Team (TMT) international experience is positively associated to international information acquisition from managerial international contacts and whether international information partially mediates the positive relationship between TMT international experience and international strategic decision rationality.Design/methodology/approachData were collected through a survey of small- and medium-sized of international Pakistani software firms.FindingsThis study reports that TMT international experience-international strategic decision rationality relationship to international information acquisition and that this information acquisition partially mediates the TMT international experience, i.e. international strategic decision rationality relationship.Practical implicationsWhen selecting the members of their TMT, international firms should pay careful attention to their international experience.Originality/valuePrevious research demonstrates that TMT international experience has a positive effect on international strategic decision rationality and that this effect is transferred to performance. This study shows that the positive effect of TMT international experience is derived from the personal international knowledge and the international information collected from managers’ international contacts. This ability to make rational international strategic decisions could have a positive effect on decision-making and firm performance.
