<div><div><div><p>The current blockchain paradigm is being hailed as an unquenchable goal to develop Hyperledger Fabric (HF)-based applications, resulting in a set of substantial enterprises shifting their networking operations, as intriguing consortia to plug the permissioned-nature of blockchain-based computing. While this practice endeavors to fundamentally revolutionize industries, one of the unavoidable problems that emerge is a lack of communication among autonomous HF-based networks, which can hinder the ongoing research landscape and consequently, have detrimental effects on its adoption. Towards this, blockchain interoperability (BI) has been heralded as the underlying concept by which communication can be derived through locating an inter-connection bridge. Considering BI’s significant traction, this paper introduces a new methodological approach to deal with the disparate nature of HF-based networks, termed OClient, for embracing two different interoperabilities (inter-network and inter-chain). This approach strategically tunes the inner working of clients by providing the global information of HF network topology that extends their conventional role as a matching service provider for facilitating opportunistic communication, in contrast to the existing solutions where typically third-parties have been exploited as the intermediaries. The paper streamlines the discussion by putting forth a pragmatic multi-HF (MHF) network scenario to formulate the disconnectivity problem, followed by constructing interaction-path-based graphs and conducting rigorous simulations. More importantly, this paper manifests experimental examples and corresponding results, providing insights across various dimensions of client-level interoperability so as to understand the impact on performance for combinations of inter-network and inter-chain scenarios. Succinctly, the results demonstrate that OClient is close to the performance of autonomous HF networks, which makes it a useful approach. Besides, this paper strives to understand how the adopted failure strategy to maintain ledger consistency contributes to performance and finally, concludes by anticipating significant future research directions towards HF interoperability.</p></div></div></div>

The Impact

Tourism in the Gulf Cooperation Council (GCC) countries has recently been considered by policymakers as a new avenue for economic diversification. Despite the considerable literature concerning the impact of tourism worldwide, only a limited number of studies have looked at the tourism sector in the GCC region or analyzed its economic, sociocultural, and environmental impacts. This article therefore conducts a systematic review of the state of the literature related to tourism in the GCC region. It provides effective insights about the current status, gaps, and challenges and proposes future research directions in this area for academics, practitioners, and policymakers with an interest in regional tourism development. The preferred reporting items for systematic reviews and meta-analyses approach was used to identify and select the papers. Some 23 papers were identified and analyzed. The majority of these studies focused on the United Arab Emirates, specifically the Dubai emirate. We found the most dominant research theme to be tourism planning.

The Impact

New opportunities and challenges are emerging thanks to the growing Internet importance and social media usage. Although practitioners have already recognized the strategic dimension of e-reputation and the power of social media, academic research is still in its infancy when it comes to e-reputation determinants in a social networks context. A study was conducted in the sports setting to explore the impact of social networks on the sportspeople's e-reputation. Whereas the study emphasized (1) the influence of social networks' perception on the sportspeople's e-reputation, and the neutral roles of (2) the motives for following sportspeople online, and (3) the negative content on the Internet, additional insights are formulated on maintaining, restoring and managing e-reputation on social networks. Finally, future research directions are suggested on the role of image to control e-reputation.

AbstractThe primary aim of the Guangzhou Twin Eye Study (GTES) is to explore the impact that genes and environmental influences have on common eye diseases. Since 2006, approximately 1300 pairs of twins, aged 7–15 years, were enrolled at baseline. Progressive phenotypes, such as cycloplegic refraction, axial length, height and weight, have been collected annually. Nonprogressive phenotypes such as parental refraction, corneal thickness, fundus photo, intraocular pressure and DNA were collected once at baseline. We are collaborating with fellow international twin researchers and psychologists to further explore links with general medical conditions. In this article, we review the history, major findings and future research directions for the GTES.

Abstract Despite a rapidly growing understanding of hoarding disorder (HD), there has been relatively limited systematic research into the impact of hoarding on children and adolescents. The goal of this paper is to suggest future research directions, both for children with hoarding behaviours and children living in a cluttered home. Key areas reviewed in this paper include (1) the need for prospective studies of children with hoarding behaviours and those who grow up with a parent with HD; (2) downward extensions of cognitive-behavioural models of adult HD that emphasise different information processing and behavioural biases in youth HD; (3) developmental research into the presentation of emerging HD in childhood compared with adulthood presentations of the disorder, with consideration of typical childhood development and unique motivators for childhood saving behaviours; (4) developmentally sensitive screening and assessment; and (5) the development of evidence-based treatments for this population. The paper concludes with a discussion of methodological suggestions to meet these aims.

Purpose This paper aims to provide a comprehensive and systematic review of the extant empirical body of knowledge regarding the impact of Guanxi on international Business-to-Business (B-to-B) relationships. Design/methodology/approach After the collection and refinement of studies that appeared in marketing, business and management literature during 1995-2018 period, a systematic review was conducted to discover the current situation and future research directions on the subject. Findings Theoretically, vast majority of the reviewed studies lacked a theoretical foundation, with the remainder anchored primarily on the resource-based view, social network theory and social exchange theory. Methodologically, Ganqing, Xinren and Mianzi are the most frequently investigated dimensions, whereas Renqing is the least investigated dimension. Data are mostly obtained from both Chinese and Western counterparts through survey and analyzed through univariate and multivariate data analysis techniques. Empirically, extant research focused on many diverse outcomes including trust, financial performance, cooperation, satisfaction, time orientation, opportunism and liability of foreignness, while under-examining the drives of Guanxi. Research limitations/implications This study provides a synthesis of extant line of research on the subject that are published in peer-reviewed international journals, which publish research in English. A meta-analysis may be conducted for providing a further detailed framework. Originality/value This study contributes to international marketing literature by providing an in-depth and synthesized inventory of knowledge to scholars; deriving a comprehensive analysis of theoretical foundations, methodological approaches and findings addressed by scholars in the field; noticing theoretical, methodological and empirical gaps to be examined; and providing future research directions.

Practical Implications

The impact of job autonomy and traits (i.e., neuroticism) on job stressor-strain relations was examined. Data were collected from 311 first-line employees and supervisors belonging to the service department of 42 enterprises. The results showed that low neuroticism negatively related with hindrance stressors, emotional exhaustion and disengagement. In addition, challenge stressors positively impacted employees' emotional exhaustion and negatively influenced employees' disengagement. However, hindrance stressors positively increased both the emotional exhaustion and disengagement of employees. Finally, results showed 3-way interactions among neuroticism, job autonomy, and stressors on strains. As predicted, the interaction of neuroticism and job autonomy moderated the relationships between challenge stressors and two strains (i.e., emotional exhaustion and disengagement), and the relationships between hindrance stressors and disengagement. Future research directions on the topic and practical implications of results are discussed.

The Impact

The Impact Tech Startup (ITS) is a new, rapidly developing type of organizational category. Based on an entrepreneurial approach and technological foundations, ITSs adopt innovative strategies to tackle a variety of social and environmental challenges within a for-profit framework and are usually backed by private investment. This new organizational category is thus far not discussed in the academic literature. The paper first provides a conceptual framework for studying this organizational category, as a combination of aspects of social enterprises and startup businesses. It then proposes a machine learning (ML)-based algorithm to identify ITSs within startup databases. The UN’s Sustainable Development Goals (SDGs) are used as a referential framework for characterizing ITSs, with indicators relating to those 17 goals that qualify a startup for inclusion in the impact category. The paper concludes by discussing future research directions in studying ITSs as a distinct organizational category through the usage of the ML methodology.

The Impact

This article examines the ways in which bilingualism influences social and cognitive development and identifies intersections between corresponding aspects of autism, to inform future research directions. Three key domains are identified: social cognition; executive functions; and social-cultural factors. In each case we describe the evidence for the impact of bilingualism in typical development and map this onto what is known about the domain in autism. We examine the methodological quality of the existing literature to make recommendations for future approaches. Results suggest a dearth of high-quality research and lack of consensus. Research priorities include the need for innovative designs to explore potential impacts of bilingualism in order to increase the validity of the evidence base for caregivers and professionals.
