Kildekompasset - å navigere seg frem til riktig referansestil

2012

One of the main tasks of an academic library is to guide students in critical evaluation and the ethical use of sources so that they can interpret, evaluate and create information in a correct and proper way. This should be integrated into the subjects, which is a huge challenge. Many students are told that they can freely select the reference style as long as they are consistent. But it is difficult to be consistent when you barely know what a reference style is. It is not easy for the librarian to answer how one refers to a governmental white paper in a self-designed reference system. To do this in a simple way, it is desirable to share the task between academic tutors and the library.  T…

Schematic or taxonomic organisation of the reality and the development of class logic

1994

Abstract The experiment studied the effect of various methods of organising reality (taxonomic vs. schematic) on success in inclusion and logical complementation tasks. Seventy-two nine-year-old children were divided into four groups on the basis of their logical structuring abilities. Using three sets of material (Animals, Plants, Means of Transportation), the subjects performed a sorting task and an evaluation task in which the taxonomic and schematic modes of organising reality were opposed. Contrary to our hypothesis, the ″;logical included' did not exhibit a greater capacity for taxonomic organisation than the “empirical includers” of the same age, either in the sorting or the evaluati…

Reverse engineering expert visual observations: From fixations to the learning of spatial filters with a neural-gas algorithm

2013

Human beings can become experts in performing specific vision tasks, for example, doctors analysing medical images, or botanists studying leaves. With sufficient knowledge and experience, people can become very efficient at such tasks. When attempting to perform these tasks with a machine vision system, it would be highly beneficial to be able to replicate the process which the expert undergoes. Advances in eye-tracking technology can provide data to allow us to discover the manner in which an expert studies an image. This paper presents a first step towards utilizing these data for computer vision purposes. A growing-neural-gas algorithm is used to learn a set of Gabor filters which give h…

Il valore delle risorse umane in sanità e le traiettorie di precariato per i giovani medici

2017

In un periodo di crisi generalizzata che colpisce tutti i settori della vita pubblica di un Paese, è bene ricordare come l'istruzione, la formazione e, più in generale, il capitale umano, contribuiscano in modo decisivo allo sviluppo socio-economico di qualsivoglia nazione. I sistemi sanitari di tutto il mondo stanno lottando per tenere il passo con i cambiamenti introdotti dai mutati scenari di salute, dalla crescente innovazione tecnologica, dalla globalizzazione in tutte le sue declinazioni e, man mano che diventano più complessi e costosi, finiscono con l'esprimere bisogni crescenti, che si riverberano sugli operatori sanitari. A livello globale è stato stimato un fabbisogno aggiuntivo …

Early Warning Systems for Food Security in West Africa: Evolution, Achievements and Challenges

2010

In West Africa, early warning systems (EWSs) for food security have been widely recognized to have contributed, in the last 20 years, to an improved ability to deal with famine emergencies. Nevertheless, despite the advancements in understanding of the environmental and socio-economic dynamics and despite the improved technologies, tackling food security remains a difficult task for decision makers as demonstrated by local food crises in many countries of the region. African Monsoon Multidisciplinary Analysis, while improving the understanding of the monsoon system, allowed us to better orient research challenges to provide EWS with improved products, effectively meeting the needs of end-us…

Sales forecasting is an essential task in retailing. In particular, consumer-oriented markets such as fashion and electronics face uncertain demands, short life cycles and a lack of historical sales data which strengthen the challenges of producing accurate forecasts. This survey paper presents state-of-the-art methods in the sales forecasting research with a focus on fashion and new product forecasting. This study also reviews different strategies to the predictive value of user-generated content and search queries.

User-Centered Design of a Scenario-Based Serious Game: Game-Based Teaching of Future Healthcare

2020

A scenario-based serious game for teaching about healthcare solutions was developed and tested in multiple iterations. The serious game captures the complexity of a real-world healthcare scenario, projecting it into a “scenario system” that can be accessed by the game participants to explore and experience the playthrough of a critical healthcare situation. The aim is to teach about existing health technology, and its uses and interactions between healthcare professionals, technologies, and patients. The platform for the serious game is mobile, such that different locations can be chosen for different scenarios. Actions of the participants trigger further actions, tasks, and storyline progr…

Checkpointing Workflows for Fail-Stop Errors

2017

International audience; We consider the problem of orchestrating the exe- cution of workflow applications structured as Directed Acyclic Graphs (DAGs) on parallel computing platforms that are subject to fail-stop failures. The objective is to minimize expected overall execution time, or makespan. A solution to this problem consists of a schedule of the workflow tasks on the available processors and of a decision of which application data to checkpoint to stable storage, so as to mitigate the impact of processor failures. For general DAGs this problem is hopelessly intractable. In fact, given a solution, computing its expected makespan is still a difficult problem. To address this challenge,…

A Knowledge-Based System for the Automatic Generation of Plant Shutdown and Startup Schedules

1988

Abstract When the shutdown of a plant, or part of it, has been decided as consequence of a major fault, the generation of a safe shutdown schedule may be, for large and complex plants, a very difficult and delicate task. The same problem may be found when the plant must be restarted after the fault has been repaired, for the generation of a start-up schedule. The use of a knowledge-based system appears to be a suitable answer to this problem, allowing a high level of safety and a very fast generation process. The paper examines the process knowledge that needs to be included in such a knowledge-based system and proposes some knowledge representation forms that appear suitable for the task t…

Design and implementation of a course scheduling system using Tabu Search

2002

Abstract Building a course timetable is a difficult and lengthy task which universities devote a large amount of human and material resources to every year. We have developed a computer package to solve this problem. The program runs on a PC and the user may set the objectives and parameters from among a wide range of possibilities. It has a user-friendly interface for the user to input the relevant data and obtain the corresponding results. The optimization process is based on a set of heuristic algorithms. The core is a Tabu Search procedure for which several strategies have been developed and tested in order to get a fast and powerful algorithm. The first tests of the package have produc…
