Yes / Big Data (BD), with their potential to ascertain valued insights for enhanced decision-making process, have recently attracted substantial interest from both academics and practitioners. Big Data Analytics (BDA) is increasingly becoming a trending practice that many organizations are adopting with the purpose of constructing valuable information from BD. The analytics process, including the deployment and use of BDA tools, is seen by organizations as a tool to improve operational efficiency though it has strategic potential, drive new revenue streams and gain competitive advantages over business rivals. However, there are different types of analytic applications to consider. Therefore, prior to hasty use and buying costly BD tools, there is a need for organizations to first understand the BDA landscape.Given the significant nature of the BDand BDA, this paper presents a state-ofthe- art review that presents a holistic view of the BD challenges and BDA methods theorized/proposed/ employed by organizations to help others understand this landscape with the objective of making robust investment decisions. In doing so, systematically analysing and synthesizing the extant research published on BD and BDA area. More specifically, the authors seek to answer the following two principal questions: Q1 –What are the different types of BD challenges theorized/proposed/confronted by organizations? and Q2 – What are the different types of BDA methods theorized/proposed/employed to overcome BD challenges?. This systematic literature review (SLR) is carried out through observing and understanding the past trends and extant patterns/themes in the BDA research area, evaluating contributions, summarizing knowledge, thereby identifying limitations, implications and potential further research avenues to support the academic community in exploring research themes/patterns. Thus, to trace the implementation of BD strategies, a profiling method is employed to analyze articles (published in English-speaking peer-reviewed journals between 1996 and 2015) extracted from the Scopus database. The analysis presented in this paper has identified relevant BD research studies that have contributed both conceptually and empirically to the expansion and accrual of intellectual wealth to the BDA in technology and organizational resource management discipline.

Yes / Sustainable operations management (SOM) can be defined as the operations strategies, tactics and techniques, and operational policies to support both economic and environmental objectives and goals. The subject of sustainability has gained much attention from both researchers and practitioners in the past 6–8 years. Most of the articles deal with sustainability from environmental perspectives, but a limited number of them integrate both economic and environmental implications or focus on trading-off between profitability, competitiveness and environmental dimensions. Moreover, there is a limited focus on modelling and analysis (MA) of SOM integrating and balancing the interests of both economic and environmental interests. Therefore, an attempt has been made in this paper to review the extant literature on SOM. The objective is to understand the definition of SOM and present the current status of research in MA, as well as future research directions in the field. Considering the recent focus of the subject, we review the literature on MA of SOM beginning in 2000 in order to make our study current and more relevant for both researchers and practitioners. Finally, a summary of findings and conclusions is reported.

No / This study explores the progress of social innovation research in a public sector context by systematically analyzing its existing body of knowledge to identify areas of societal impact and reveal areas of limitations and potential further research. The findings revealed that most of the studies on social innovation in the public sector are conceptual in nature. The article presents propositions based on the diagnosed limitations of research in the area.

No / Outsourcing, an operations strategy that influences the performance of a supply chain, has become an important component of global operations management. An effective global sourcing strategy helps companies to manage the flow of parts and finished products in meeting the needs of overseas and domestic markets. Outsourcing reduces the cost of assets, facilitates core competencies to reduce production costs, leads to strategic flexibility and reduces administrative and overhead costs. Some of the reasons why companies are against outsourcing include integration challenges, sacrificing their competitive base, opportunistic behaviour, rising transaction and coordination costs, limited innovation, and higher procurement costs. Despite these shortcomings, outsourcing will continue to play an important role in enhancing organizational competitiveness. Therefore, an attempt has been made to review the literature on outsourcing with particular reference to Performance Measures and Metrics (PMMs) used in arriving at outsourcing decisions. The main objective of this paper is to present a taxonomy (classification) of PMMs in outsourcing decisions at the pre-outsourcing, during-outsourcing, and post-outsourcing stages. Also, based on the literature review and analysis, an attempt is made to determine a list of specific tools and techniques for PMMs in outsourcing. Finally, the limitations of the paper and future research directions are presented.

Yes / Electronic word-of-mouth (eWOM) plays an important part in consumer purchase decision. The way consumers perceive the persuasiveness of eWOM message can affect their attitude, and purchase intention, and hence sales. Thus, the topic of persuasiveness of eWOM communications has received much attention from scholars. The objective of this paper is to provide a brief review of the existing literature related to the effectiveness of eWOM communications and offer an overview of the determinants of eWOM persuasiveness. This paper contributes to the existing eWOM literature by reviewing the existing studies on eWOM communications, identifying gaps in the current research and providing directions for future research.

Yes / Smart cities employ information and communication technologies to improve: the quality of life for its citizens, the local economy, transport, traffic management, environment, and interaction with government. Due to the relevance of smart cities (also referred using other related terms such as Digital City, Information City, Intelligent City, Knowledge-based City, Ubiquitous City, Wired City) to various stakeholders and the benefits and challenges associated with its implementation, the concept of smart cities has attracted significant attention from researchers within multiple fields, including information systems. This study provides a valuable synthesis of the relevant literature by analysing and discussing the key findings from existing research on issues related to smart cities from an Information Systems perspective. The research analysed and discussed in this study focuses on number of aspects of smart cities: smart mobility, smart living, smart environment, smart citizens, smart government, and smart architecture as well as related technologies and concepts. The discussion also focusses on the alignment of smart cities with the UN sustainable development goals. This comprehensive review offers critical insight to the key underlying research themes within smart cities, highlighting the limitations of current developments and potential future directions.

Yes / Purpose: Despite the potential of social media in emerging markets (EMs), only few studies published in high quality information systems (IS) journals that have addressed issues related to social media in the context of EMs. This study aims to analyse existing research related to social media published in high quality IS journals for exploring initial research trends, emerging themes, limitations and future research directions in the context of emerging markets. Design/methodology/approach: This study conducted systematic review of 22 articles on social media, which were published in the “Senior Scholars Basket of IS Journals and Information Systems Frontiers” from 1997 to 2017. Manual literature search approach (i.e. screening through table of contents of each journal) was employed to identify relevant articles. The content of relevant articles was systematically analysed and synthesised along with keyword analysis to understand research trends on social media related issues in the emerging markets context. Findings: The study identified four major themes from existing research on the social media in the context of emerging markets, namely: 1) Social media frameworks; 2) Social media and consumers; 3) Social media and organisations; and 4) Social media and society with majority of the studies focusing on consumers. Single Subject was found as the major limitation with studies analysed focusing on single platform/country/domain hindering the generalizability whereas including new exogenous variable to improve the validity of existing studies emerged as main future research direction. Originality/value: This study conducted literature review on social media in EMs, which has not been undertaken yet. Moreover, it employed manual search (an effort and time intensive approach) to overcome the shortcomings of keyword search to identify, locate, select and analyse the social media literature in the context of emerging markets.

Yes / Social media facilitates and enhances communication between businesses and customers. Nowadays, although it is commonly recognised that companies implement social media into their marketing activities, it is also acknowledged that companies struggle to calculate the return on investment (ROI) from social media marketing efforts as most of them focus only on certain tangible outcomes such as the impact on sales and purchases. Attempts have been made by researchers to identify how to measure key impacts of social media in relation to marketing; however, there remains a lack of empirical data and no comprehensive overview of what “ROI” can mean for an organisation seeking returns on their social media adoption. By knowing how to measure ROI from social media, companies can produce valuable insights which can help enhance marketing strategies in promoting their products/services. Thus, the aim of this chapter is to provide a review of ROI in social media marketing with a particular focus on intangible outcomes such as brand awareness, customer engagement/relationship and eWOM.

Yes / The complex and interdependent nature of smart cities raises significant political, technical, and socioeconomic challenges for designers, integrators and organisations involved in administrating these new entities. An increasing number of studies focus on the security, privacy and risks within smart cities, highlighting the threats relating to information security and challenges for smart city infrastructure in the management and processing of personal data. This study analyses many of these challenges, offers a valuable synthesis of the relevant key literature, and develops a smart city interaction framework. The study is organised around a number of key themes within smart cities research: privacy and security of mobile devices and services; smart city infrastructure, power systems, healthcare, frameworks, algorithms and protocols to improve security and privacy, operational threats for smart cities, use and adoption of smart services by citizens, use of blockchain and use of social media. This comprehensive review provides a useful perspective on many of the key issues and offers key direction for future studies. The findings of this study can provide an informative research framework and reference point for academics and practitioners.

Yes / This article undertakes a literature review on such articles on social media and citizen-centric e-government services. This research uses 139 articles to perform the intended literature review. The keywords analysis of these articles indicates that Web 2.0, participation and open government/ open data were some of the frequently used keywords in addition to the two major themes of e-government and social media on which all the articles were searched for. The analysis of research methods indicated that majority of the studies were analytical, conceptual, descriptive, or theoretical in nature. The theoretical analysis however indicated that there is a lack of theory-based research in this area. The review of literature indicated that research themes such as electronic participation, engagement, transparency, communication/interaction, trust, security and collaboration are some of the most frequently used categories under this area of research. A research framework has also been proposed from the key themes emerging from the review.
