Social–ecological connections across land, water, and sea demand a reprioritization of environmental management
2022
International audience; Despite many sectors of society striving for sustainability in environmental management, humans often fail to identify and act on the connections and processes responsible for social-ecological tipping points. Part of the problem is the fracturing of environmental management and social-ecological research into ecosystem domains (land, freshwater, and sea), each with different scales and resolution of data acquisition and distinct management approaches. We present a perspective on the social-ecological connections across ecosystem domains that emphasize the need for management reprioritization to effectively connect these domains. We identify critical nexus points rel…
The Shape of Interoperability: Reviewing and Characterizing a Central Area within eGovernment Research
2012
Interoperability has been discussed and studied for more than a decade. While early discussions were very conceptual, interoperability is increasingly seen as one of the key enablers of the promised benefits from eGovernment. Consequently, and not surprisingly, a considerable amount of research has been published related to interoperability. However, a conceptual model of the interoperability domain is currently missing. We thus propose such a model based on an extensive review of a subset of the eGovernment literature published in highly ranked information systems, public administration and eGovernment journals. The model outlines and discusses actors, activities, contextual factors, effec…
Improving Serendipity and Accuracy in Cross-Domain Recommender Systems
2017
Cross-domain recommender systems use information from source domains to improve recommendations in a target domain, where the term domain refers to a set of items that share attributes and/or user ratings. Most works on this topic focus on accuracy but disregard other properties of recommender systems. In this paper, we attempt to improve serendipity and accuracy in the target domain with datasets from source domains. Due to the lack of publicly available datasets, we collect datasets from two domains related to music, involving user ratings and item attributes. We then conduct experiments using collaborative filtering and content-based filtering approaches for the purpose of validation. Ac…
Interoperability of Information Systems
2005
An information system is a multilevel system characterized by a “data” level, a “behavioral” level, and a “communication” level. The data level represents the data stored by the system. The behavioral level represents management and production processes carried out by the system. The processes can interact with the data level to extract, generate, and store data. The communication level relates to the network used to exchange data and activate processes between geographically distant users or machines.
Cross-Domain Recommendations with Overlapping Items
2016
In recent years, there has been an increasing interest in cross-domain recommender systems. However, most existing works focus on the situation when only users or users and items overlap in different domains. In this paper, we investigate whether the source domain can boost the recommendation performance in the target domain when only items overlap. Due to the lack of publicly available datasets, we collect a dataset from two domains related to music, involving both the users’ rating scores and the description of the items. We then conduct experiments using collaborative filtering and content-based filtering approaches for validation purpose. According to our experimental results, the sourc…
Towards a dynamic systems approach to the development of language and music - Theoretical foundations and methodological issues
2009
Music and language are considered as distinct auditory systems that serve different communicative uses. From the perspective of infants rather inexperienced with their native musical and linguistic systems, these differences are less apparent. One of the enduring puzzles related to human cognitive development is the question of how children acquire these complex systems with such effortlessness and speed, and how developmental change can be explained. Dynamic systems theory (DST) can make significant contributions to our understanding of cognitive development, and has already been successfully applied to first and second language development. By drawing together findings from various scient…
Cross-domain mapping processes in the perception of post tonal music
2009
Theories of embodied cognition state that knowledge is built by means of cross-domain mapping processes between different domains of experience. Recent research informs about the presence of mapping processes in the reception of both tonal and atonal music. A previous experiment suggested the occurrence of mappings between visual attributes and interpretative features in atonal music. However, these results were obtained with musicians; therefore, it is unknown to what extent they are equally valid to non-musicians. This study aims at examining the incidence of interpretative expression within the visual-musical mapping process. Three versions (two expressive and one deadpan) of an atonal m…
