Mapping gamification in the consumption context: A systematic literature review
Gaspar, J. M.; Loureiro, S. M. C.; Rosado-Pinto, F.This research provides an overview of the current state of the art in gamification. To do this, a systematic review of the literature (Tranfield et al., 2003; Loureiro et al., 2020) was conducted to map gamification. This systematic analysis is composed of articles, conference papers, and books published between 2004 and October 2023. This study analyzes the objectives, methodologies, theories, constructs (ante...
How and where satellite cities form around a large city: bifurcation mechanism ...
Ikeda, Kiyohiro; Aizawa, Hiroki; Gaspar, J. M.We investigate economic agglomerations in a long narrow economy, in which discrete locations are evenly spread over a line segment. The bifurcation mechanism of a monocentric city at the center is analyzed analytically to show how and where satellite cities form. This is an important step to elucidate the mechanism of the competition between a large central city and satellite cities, which is taking place world...
How social interactions matter when distance dies?
Osawa, Minoru; Gaspar, J. M.We consider an economic geography model with two inter-regional proximity structures, one due to trade linkages and the other due to social interactions. We investigate how the network structure of social interactions, or the social proximity structure, affects the timing of endogenous agglomeration and the spatial distribution of workers across regions. Endogenous agglomeration emerges when inter-regional trad...
Breaking and sustaining bifurcations in SN-Invariant equidistant economy
Aizawa, H.; Ikeda, K.; Osawa, M.; Gaspar, J. M.This paper elucidates the bifurcation mechanism of an equidistant economy in spatial economics. To this end, we derive the rules of secondary and further bifurcations as a major theoretical contribution of this paper. Then we combine them with pre-existing results of direct bifurcation of the symmetric group SN [Elmhirst, 2004]. Particular attention is devoted to the existence of invariant solutions which retai...
Revealing higher than expected meiofaunal diversity in Antarctic sediments: a m...
Fonseca, V. G.; Sinniger, F.; Gaspar, J. M.; Quince, C.; Creer, S.; Power, Deborah M.; Peck, Lloyd S.; Clark, Melody S.An increasing number of studies are showing that Antarctic mega- and macrofauna are highly diverse, however, little is known about meiofaunal biodiversity in sediment communities, which are a vital part of a healthy and functional ecosystem. This is the first study to analyse community DNA (targeting meiofauna) using metabarcoding to investigate biodiversity levels in sediment communities of the Antarctic Penin...
Tauroursodeoxycholic acid protects retinal neural cells from cell death induced...
Gaspar, J. M.; Martins, A.; Cruz, R.; Rodrigues, C. M. P.; Ambrósio, A. F.; Santiago, A. R.Diabetic retinopathy is one of the most frequent causes of blindness in adults in the Western countries. Although diabetic retinopathy is considered a vascular disease, several reports demonstrate that retinal neurons are also affected, leading to vision loss. Tauroursodeoxycholic acid (TUDCA), an endogenous bile acid, has proven to be neuroprotective in several models of neurodegenerative diseases, including m...
