Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Geospatial Health:development of a maturing scientific journal 2006-2023
No full textAbstractGeospatial Health is an international, peer-reviewed scientif-ic journal produced by the International Society of Geospatial Health. The journal covers all aspects of geographical informa-tion system (GIS) applications, remote sensing and other spatial analytic tools focusing on human and veterinary health.Our study illustrates how the interdisciplinary domain of Geo-spatial Health has evolved over time by analysing the published content of the journal for the period 2006 – 2023.A systematic bibliometric analysis was conducted based upon all (review) articles and editorials published in Geospatial Health. To capture key research topics, methods & techniques, geographic areas studied, and temporal development, our analysis proceeds through three stages: (1) high-frequency keywords identification, (2) co-occurrence analysis that identifies how high-frequen-cy keywords are related, and (3) cluster analysis that identifies groups of interlinked keywords. Impact analysis based on citation counts is included.Original research papers represent the largest publication catego-ry, followed by editorials, and review papers. Three quarters of the publications focus on human health, the rest is on veterinary applications. Geographic focus was initially largely on Africa and Asia. This remained up to around 2020 after which a strong decline in African studies, and a major increase of Asian studies is observed. Initially, focus was on schistosomiasis and malaria, but the scope widened to 35+ different diseases, injuries and risk factors. Over time there is growing attention for non-communi-cable disease such as cancer and obesity. Spatial and statistical analytical techniques used are diverse and exhibit increasing so-phistication over time.Scaling up the analysis to include related journals is straightfor-ward. This would enable a solid understanding of the temporal de-velopment of the scientific discipline Geospatial Health as a whol
Evaluating the effects of consecutive hurricane hits on evacuation patterns in Dominica
Get PDFThe Caribbean island of Dominica is at constant risk of being hit by tropical storms during the hurricane season. Therefore, Dominica and areas in similar situations need to raise their resilience to natural hazards. The potentialconsequences of climate change intensify this risk. After a hurricane hit, repair of damage to buildings and infrastructure can take several months. As hurricane frequency is increasing and time between hurricanes fluctuates, modeling sequences of hurricane events can help to determine different evacuation strategies. This paper introduces an agent-based model, simulating two hurricane events in one season. The prototype simulates the movement of evacuees over a road network and damage to buildings and infrastructure. Initial results show marked differences between road movements of evacuees during a second evacuation. Although shifts in the average shelter occupation are small (up to 2%) for our case study, this can indicate that adjustments to shelter capacities are necessary
