Narrowing the Theory’s or Study’s Scope May Increase Practical Relevance

2019

Numerous articles in top IS journals note as a limitation and lack of generalizability that their findings are specific to a certain type of technology, culture, and so on. We argue that this generalizability concern is about limited scope (e.g., explanatory breadth). The IS literature notes this preference for generalizability as a characteristic of good science and it is sometimes confused with statistical generalizability We argue that such generalizability can be in conflict with explanation or prediction accuracy. An increase in scope (e.g., increasing explanatory breadth) can decrease explanation or prediction accuracy. Thus, in sciences such as cancer research, where explanation and …

Representation and retrieval of uncertain temporal information in museum databases

Representation and retrieval of uncertain temporal information in museum databases

2012

An implementation-oriented model to represent uncertain temporal information in databases is proposed. Temporal information is presented to the user as anchored time intervals with optional beginning and end dates. The model accounts for both instants and intervals, and can be applied to uncertain dates by leaving days and months optional, or by using symbolic constraints that present additional time granularities. The model is defined using conventional relational database structures to support ease of deployment and integration to legacy systems with efficient query capabilities. The model is based on experiences with an existing museum database and highlights challenges related to tempor…

ModeLTER : modelling of landscapes and territories over the long term, the members of an European Associated Laboratory (EAL) in CAENTI.

2006

International audience; The aim of this new project is the modelisation of landscapes and territories over the long term. This has been a topic that engaged the proposed research team for several years, particularly in the frame of two European projects, Archeomedes I & II, during the 1990s (Van der Leeuw S., Favory F., Fiches J.- L. (eds.) 2003, Favory F., Girardot J.-J., van der Leeuw S. 2004). Both French and Slovenian teams were involved in the project by Professors S. Van der Leeuw and Z. Stančič. Since this period, the collaboration of French and Slovenian researchers increased in activity, and it finds now a new organization in an European Associated Laboratory, linking archaeologist…

Développement territorial et développement agricole durable

2012

L'objectif de la communication est de montrer comment au travers d'une approche pluri-disciplinaire, l'ancrage territorial de l'agriculture est une clé de compréhension de la durabilité de l'agriculture de territoires mixtes, périurbains ou ruraux-touristiques. La dimension socio-spatiale qu'introduit cet angle d'analyse conduit à rapprocher géographie et agroéconomie au sein d'une démarche qui vise à modéliser la complexité et la multi-dimensionnalité du développement agricole. Cette approche est appliquée à un territoire dominé à la fois par l'agriculture et le développement touristique, situé en Corse (Balagne). L'agriculture, entre pression foncière et valorisation touristique du patrim…

Local and territorial determinants in the realization of public–private–partnerships: an empirical analysis for Italian provinces

2019

ABSTRACT Relational networks and intangible factors are crucial elements for the competitiveness of a territory. Public–Private–Partnerships (PPPs), in particular, allow for the provision of goods and services that favour the exploitation of complementarities between public and private resources. They aim at promoting an increase in the overall efficiency of investment projects through a complex mechanism that distributes risk and revenues among stakeholders. This paper examines the local and territorial determinants of PPPs through an econometric analysis based upon Italian municipal data, grouped at the provincial level. Using a tobit model, we analyse the relationship between the realiza…

Creating the Socio-technical Context Needed to Derive Benefits from Big Data Initiatives in Healthcare

2021

The application of big data in healthcare typifies a complex socio-technical sys- tem. However, although research and practice have advanced the technical aspects of big data, comparable advancements in the social aspects (i.e., human and structural aspects) are lagging. Literature, especially on socio-technical theory, suggests that organizations may only derive benefits from big data initiatives when technical initiatives are adequate- ly complemented by social interventions. Thus, seeing that big data is receiving consider- able attention in healthcare, researchers have called for further research into the social aspects of the application of big data in healthcare. Adopting a socio-tech…

Navigation Performance Evaluation for AutomaticGuided Vehicles

2015

International audience; —Automatic guided vehicles (AGVs), an industrial form of a mobile robot,typically navigate using a central computer commanding AGV movement on predefined paths. How well they follow these paths is not well-defined in research articles and their performance is reported in non-standard manufacturer specifications. Furthermore, AGV technology is advancing towards vision guidance to map and localize their position from onboard the vehicle, whereas performance evaluation of advanced navigation techniques is just beginning. This paper describes AGV experiments using ground truth measurement comparisonfor performance evaluationof AGV navigation. A generic test procedure and…

Survey of Research for Performance Measurement of Mobile Manipulators

2016

International audience; This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles when compared to other mobile manipulator research areas. The survey provides a literature review of mobile manipulator research with examples of experimental applications. The survey also provides an extensive list of planning and control references as this has been the major research focus for mobile manipulators which factors into performance measurement of the system. The survey then reviews performance metrics considered for mobile robots, robot arms, and mobile manipulators and the systems that measu…

On the Choice of the Extracellular Vesicles for Therapeutic Purposes

2019

Extracellular vesicles (EVs) are lipid membrane vesicles released by all human cells and are widely recognized to be involved in many cellular processes, both in physiological and pathological conditions. They are mediators of cell-cell communication, at both paracrine and systemic levels, and therefore they are active players in cell differentiation, tissue homeostasis, and organ remodeling. Due to their ability to serve as a cargo for proteins, lipids, and nucleic acids, which often reflects the cellular source, they should be considered the future of the natural nanodelivery of bio-compounds. To date, natural nanovesicles, such as exosomes, have been shown to represent a source of diseas…
