Effectiveness of Exergame Intervention on Walking in Older Adults : A Systematic Review and Meta-Analysis of Randomized Controlled Trials

2021

Objective. The objective of this review was to systematically evaluate the effectiveness of exergaming on walking in older adults. In addition, the aim was to investigate the relationship between the exergaming effect and age, baseline walking performance, exercise traits, technology used and the risk of bias. Methods. A literature search was carried out in the databases MEDLINE, CINAHL, CENTRAL, EMBASE, WoS, PsycInfo and PEDro up to January 10, 2020. Studies with a Randomized Controlled Trial (RCT) design, people ≥60 years of age without neurological disorders, comparison group with other exercise or no exercise, and walking related outcomes were included. Cochrane RoB2, meta-analysis, met…

A System-based View of Blockchain Governance

2023

Abstract CONTEXT Governance is crucial in achieving the success and sustainability of blockchain systems. However, blockchain governance is multi-faceted, complex, dynamic, and challenging due to its decentralized nature and automatically enforced rules and mechanisms. OBJECTIVES This study aims to advance the theory of blockchain governance and support practitioners to deepen the researchers’ and practitioners’ understanding of blockchain governance. METHODS The study is a systematic literature review of 75 articles that applies systems theory to conceptualize blockchain governance as a system and parsimoniously organize its interrelated elements into a conceptual model. RESULTS The paper …

The effects of motor skill and physical activity interventions on preschoolers' cognitive and academic skills: A systematic review

2022

The present systematic review aimed to investigate the methodological quality and the effects of fundamental motor skills and physical activity interventions on cognitive and academic skills in typically developing 3 to 7-year-old children. The review was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A literature search was carried out in April 2020 using seven electronic databases. The methodological quality of the studies was assessed with the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool. Cohen's d effect size calculations and post hoc power analyses were conducted for the in…

Cognitive and Academic Outcomes of Fundamental Motor Skill and Physical Activity Interventions Designed for Children with Special Educational Needs: …

2022

This systematic review aimed to investigate the methodological quality and the effects of fundamental motor skills and physical activity interventions on cognitive and academic skills in 3- to 7-year-old children with special educational needs. The review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) statement. A literature search was carried out in April 2020 (updated in January 2022) using seven electronic databases, including ERIC, Scopus, Web of Science, PsycINFO, CINAHL, PubMed, and SPORTDiscus. The methodological quality of the studies was assessed with Effective Public Health Practice Project (EPHPP) Quality Asses…

Staying at the front line of literature: How can topic modelling help researchers follow recent studies?

2021

Staying at the front line in learning research is challenging because many fields are rapidly developing. One such field is research on the temporal aspects of computer-supported collaborative learning (CSCL). To obtain an overview of these fields, systematic literature reviews can capture patterns of existing research. However, conducting systematic literature reviews is time-consuming and do not reveal future developments in the field. This study proposes a machine learning method based on topic modelling that takes articles from a systematic literature review on the temporal aspects of CSCL (49 original articles published before 2019) as a starting point to describe the most recent devel…

How can algorithms help in segmenting users and customers? : A systematic review and research agenda for algorithmic customer segmentation

2023

What algorithm to choose for customer segmentation? Should you use one algorithm or many? How many customer segments should you create? How to evaluate the results? In this research, we carry out a systematic literature review to address such central questions in customer segmentation research and practice. The results from extracting information from 172 relevant articles show that algorithmic customer segmentation is the predominant approach for customer segmentation. We found researchers employing 46 different algorithms and 14 different evaluation metrics. For the algorithms, K-means clustering is the most employed. For the metrics, separation-focused metrics are slightly more prevalent…

Etic and emic data production methods in the study of journalistic work practices : A systematic literature review

2023

This methodological paper discusses the application of etic and emic perspectives in producing data sets for the study of journalistic praxis. The concepts refer to the researcher-analyst’s and the practitioner-informant’s viewpoints, respectively, and that being the case, they have inherent weaknesses if used independently. We argue that these shortcomings can be mitigated through an integrated application of the concepts and by seeing the two perspectives as complementary to each other. Combining etic and emic perspectives will allow for a more comprehensive understanding of complex yet routinized real-life behaviour such as journalistic work. Following the appraisal of the etic-emic comb…

Typical and Atypical Development of Visual Expertise for Print as Indexed by the Visual Word N1 (N170w) : A Systematic Review

2022

The visual word N1 (N170w) is an early brain ERP component that has been found to be a neurophysiological marker for print expertise, which is a prelexical requirement associated with reading development. To date, no other review has assimilated existing research on reading difficulties and atypical development of processes reflected in the N170w response. Hence, this systematic review synthesized results and evaluated neurophysiological and experimental procedures across different studies about visual print expertise in reading development. Literature databases were examined for relevant studies from 1995 to 2020 investigating the N170w response in individuals with or without reading disor…

Nordic research on educational and vocational guidance: a systematic literature review of thematic features between 2003 and 2016

2018

Educational and vocational guidance has received increased attention with regard to policymaking in the Nordic countries over the last 15 years. This has led to a growing interest in research-based knowledge. Updating an earlier article, we undertake a systematic literature review of guidance research in the Nordic countries during this 15-year period. Features and themes, both country-specific and in the region as a whole, are revealed through the analysis of a variety of research documents. Therefore, this article provides insight into research-based knowledge grounded in the Nordic context—relevant for both practitioners and policymakers on a national, Nordic, and international level. pe…
