Purpose The purpose of this paper is to present a systematic review of the available literature on value co-creation (VCC) and provide insightful future directions for research in this domain. Design/methodology/approach The extant literature on VCC has been reviewed by collecting relevant research papers based on certain specified delimiting criteria. A total of 110 research papers have been analysed to gain useful insights into VCC literature. Findings The study analyses the literature on VCC and provides a clear distinction between VCC and its closely related constructs in the literature. The study also draws significant insights from the VCC literature based on some specific parameters. Some frequently used theoretical perspectives have been discussed in the study, thus pointing towards a few alternative theories that can be used for future research. Finally, specific trends emerging from the literature have been discussed that provide a comprehensive understanding of the research inclinations of this concept, along with future scopes of research in the VCC domain. Research limitations/implications The papers were selected for this study based on some delimiting criteria. Thus, the findings cannot be generalised for the entire research on VCC. Originality/value This paper fulfils the need for a systematic review of the extant literature on VCC. The study synthesises literature and bibliography on VCC from 2004 to 2019 to benefit both academics and practitioners and gives some directions to advance this domain of literature.

Purpose The purpose of this study is to clarify the relationship between two sub-constructs of heavy work investment: work engagement and workaholism. Design/methodology/approach The authors conducted a systematic review and meta-analysis to synthesize and critically assess existing research on the relationship between these concepts. Findings The review revealed three major shortcomings of the extant literature: a dichotomous perspective, variations in measurements and the unaddressed complexity of the relationship. Originality/value Based on these findings, this study provides a discussion on the limitations and suggestions for future research on work engagement and workaholism, including using a person-centered approach.

Abstract Background: Because of its analgesic and light sedative properties, the highly selective alpha-2 adrenergic receptor agonist dexmedetomidine (DEX) has been suggested for the treatment of septic patients, but its effect on the duration of mechanical ventilation remains unclear. The present study was conducted to review the extant literature in DEX and determine its influence on ventilation time in adult septic patients. Methods: Databases of PubMed, Cochrane, and EMBASE were applied till 20th January 2019 without language restriction. The searching strategy as following: sepsis OR septic AND mechanical ventilation AND dexmedetomidine. Two authors screened titles, abstracts, and even articles to meet the including criterion independently. In addition, references of related articles or reviews were also referred. Data was recorded in a table and analyzed using the software of Review Manager 5.0. Results: Four studies with a total of 349 patients were included. Three trials with 267 patients revealed the effect of DEX on duration of mechanical ventilation, two trials with 264 patients on ventilator-free days and four trials with 334 patients on 28-day mortality. The analyzed results indicated that DEX was not associated with significantly different durations of mechanical ventilation (MD 0.65, 95% CI, -0.13 to 1.42, P = 0.10). However, there were significant differences in ventilator-free days (MD 3.57, 95% CI, 0.26 to 6.89, P = 0.03) and 28-day mortality (RR 0.61, 95% CI, 0.49 to 0.94, P = 0.02) in the septic patients. Conclusion: Administration of DEX for sedation in septic patients was not associated with the duration of mechanical ventilation, but it increased the ventilator-free days and reduced 28-day mortality.

AbstractThe rise and global reach of the corporate foundation (CF) phenomenon has attracted the attention of academic researchers and practitioners and led to a plurality of definitions and understandings. This definitional fuzziness notwithstanding, the term hybridity is widely used as the defining characteristic to describe a CF’s position between business and civil society and its diverse interlinkages with its founding company. However, the extant literature has seldom explained what hybridity signifies, when it occurs and how it is shown. This paper presents the findings of a systematic review of the academic and gray literature on CFs. Based on 80 publications covering 30 countries worldwide, this study proposes 15 characteristics along four global themes as a comprehensive set to account for the complexity of CFs. It develops propositions for a fine-grained understanding of what constitutes the hybrid nature of CFs at the strategic, organizational and contextual levels. Accordingly, this study suggests ways forward by revealing questions that require further research toward a better understanding of the CF phenomenon.

Abstract Background: Autism spectrum disorder (ASD) symptoms are usually observed by the age of 2 years. However, the mechanism of ASD is still encompassed in a block box and no identified cure exists. Based on accumulating evidence, intensive early treatment such as physical activity or exercise can make a significant difference in the cognitive control and development in children with ASD. This study aims to update the knowledge on extant literature and explore the efficacy of physical activity intervention strategies (PAIS) on cognitive functions in children with ASD. Methods: A systematic review and network meta-analysis will be conducted following the preferred reporting items for systematic review and meta-analysis protocols for Network Meta-Analyses (PRISMA-NMA). Nine bibliographic databases (APA PsycInfo, Cochrane Central Register of Controlled Trials, Dimensions, ERIC, MEDLINE Complete, PubMed, Scopus, SPORTDiscus, Web of Science) will be systematically searched to screen eligible articles based on a series of inclusion and exclusion criteria. A study will be considered for inclusion if the study: (a) is not classified as a systematic review with or without meta-analysis; (b) is published from inception to date; (c) includes children aged 0-12 years with ASD; (d) quantitively measures cognitive outcomes; (e) treatment includes at least one PAIS. The internal validity and quality of evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Statistical analyses will be produced in RStudio 3.6 with the BUGSnet package and Comprehensive Meta-Analysis 3.3. Discussion: This study will provide an updated review of the extant literature by using an appropriate network meta-analytic model and address the questions regarding efficacy of PAIS that significantly impact cognitive functions in children with ASD with implications for future decision making. Systematic review registration: PROSPERO CRD42021279054.

Hostile masculinity and its components (i.e., sexual dominance, hostility toward women, adversarial sexual beliefs, rape myth acceptance, and acceptance of interpersonal violence) have received considerable research attention as predictors of male-perpetrated sexual aggression toward women. The current systematic review sought to synthesize and organize the extant literature. Studies were included in the systematic review if they were published in a peer-reviewed journal between the years 1990 and 2020, contained a male sample within the United States, analyzed quantitative data, and examined at least one component of hostile masculinity and its association with sexual aggression. Literature searches were conducted in three academic databases, and additional records were identified through references sections from known hostile masculinity research. A total of 95 articles met inclusion criteria and were integrated into the overview of results. The reviewed literature provided broad support for the association between hostile masculinity and sexual aggression, including evidence for the theoretical framework posited by the confluence model of sexual aggression. Prevention efforts are likely to find success by modifying hostile masculine characteristics among men, particularly within problematic environmental contexts. However, the review also highlighted the need for a uniform conceptualization and operational definition of hostile masculinity. Additionally, empirical work with diverse samples is necessary to determine the scope of generalizability and potential subcultural distinctions. Future research that addresses these limitations will contribute to the understanding and prevention of sexual aggression beyond what is provided by the extant literature.

When considering the field of events, an important initial step is to consider the definition of an event. The goal of this article was twofold, first to take a novel approach in defining an event by considering the contextual aspects of an event from the traditional definitions, but adding the perspective of the attendee; and second to develop a typology focused on a unified definition of the field of events relational to the extant literature. The definition of an event is an occurrence that has a time element, two or more participants, is planned, and is a unique opportunity. A systematic review of extant literature was conducted in order to define the field of events. A total of 95 articles were analyzed. The field of events is characterized as having four major categories: professional, entertainment, social, and common cause. Within these four categories there are 20 types of events, all of which meet the four components of the definition of an event.
