Feeding, cooking, sharing : a brief social history of food
2020
This work addresses the food system as a complex structure connected to the environment, like a living organism. It uses the contributions from multiple fields (including anthropology, nutritional, medicine, and economics) to establish connections between analytically disparate fields in order to highlight their transformations over time and space. It also studies social organisation over millions of years to understand the synergy between the environment, extraction technologies, economic and political structures, and the resulting cooking environments (each with their own social construction of tastes) as conditioning factors for sickness and death. In short, it delves into the anthropolo…
Reading Debates Politically
2017
This chapter focuses on the concept of debate, taking the concept of ‘political literacy’ as point of departure. The concept of political literacy means that it is crucial to be willing and competent to judge actions, situations, practices and institutions in terms of political struggle. What kinds of aims can we identify in various utterances, arguments or topoi, and how may we assess their consequences? Based on this idea of political literacy, our leading thesis in this chapter is that parliamentary debate, as it was formed and is practised in the British parliament at Westminster, forms an approximation to the ideal type of debate. The ideal type allows the classification of the structu…
Bayesian Estimation of Political Transition Matrices
1994
A decision framework is used to propose a procedure designed to estimate the reallocation of the vote of each individual party between two consecutive political elections, given the results of the elections, the information provided by a sample survey, and some assumptions on the hierarchical structure of the population.
Computer-supported collaborative inquiry learning and classroom scripts: Effects on help-seeking processes and learning outcomes
2011
This study examined the influence of classroom-script structure (high vs. low) during computer-supported collaborative inquiry learning on help-seeking processes and learning gains in 54 student pairs in secondary science education. Screen- and audio-capturing videos were analysed according to a model of the help-seeking process. Results show that the structure of the classroom script substantially affects patterns of student help seeking and learning gain in the classroom. Overall, students in the high-structured classroom-script condition sought less help but learnt more than those in the low-structured classroom-script condition.

New perspective of learner-centered education in nowadays didactics
2017
An approach to education that is based on the educational context in which the student comes and track progress in achieving the learning objectives. The learner-centred education learning places the responsibility on the shoulders of students, while the teacher takes responsibility for facilitating the education process. The approach tends to be unique, flexible, competency-based methodology and not always varied in time and space constrained. Teaching will have complex changes, so if, traditionally, it is just a business communication / transmission of knowledge, actual perspectives follows specifically aims in organizing and managing learning processes. According to the researchers in th…
Using Cloud, Modularity, and Make-to-Upgrade Strategy for Integrating Customized-Oriented Supply Networks
2013
In the current global business individual demand play crucial roles. Customized-oriented supply networks are being proliferated in manufacturing industries, yet integration of their members is still quite challenging. As a practical solution, in this paper a new collaborative approach out of modularity structure, cloud computing, and a novel production strategy, called Make-to-Upgrade (MTU), is suggested. The complementary aspects of these techniques are highlighted and briefly explained here. MTU is as a strategy for future products with new characteristics, e.g., upgradability.
VoxelMages: a general-purpose graphical interface for designing geometries and processing DICOM images for PENELOPE
2016
The design and construction of geometries for Monte Carlo calculations is an error-prone, time-consuming, and complex step in simulations describing particle interactions and transport in the field of medical physics. The software VoxelMages has been developed to help the user in this task. It allows to design complex geometries and to process DICOM image files for simulations with the general-purpose Monte Carlo code PENELOPE in an easy and straightforward way. VoxelMages also allows to import DICOM-RT structure contour information as delivered by a treatment planning system. Its main characteristics, usage and performance benchmarking are described in detail.
Explorations of familiarity produced by words with specific combinations of letters
2010
We explore familiarity-based recognition using a paradigm devised by Parkin et al. (2001). The task consists of the creation of two lists of words written with one of two different subsets of letters of the alphabet. We manipulated study time (50, 100, 200, 500 ms per word) of words with different letter probabilistic structure to those originally used by Parkin et al. Letter-based familiarity responding was robust and present even at rates producing otherwise chance performance. A second experi- ment and structural equation modelling led us to interpret the results from the point of view of a theory that takes into account the processing of similarities and differences (Hunt & MacDaniel, (…
Computer Simulation Paradigm Regarding the Structure and Mechanical Characteristics of Human Long Bones
2013
Given the complex form of the long bones, a quality method of geometrical modeling which provides a good result is that of the 3D modeling by reconstruction, using the principles of reverse engineering. One of the important problems that shall be taken into consideration while modeling is the one concerning the real structure of the bones. This aspect presents a lot of importance because from the point of view of the mechanical behavior, the bones are neither homogenate structures. In this paper a study of the long bones structures is undergone, and in relation to the modelated element (the human tibia) it is divided in areas (called constructive-anatomical entities) of different mechanical…
An analysis of ego network communities and temporal a affinity for online social networks
2017
The wide diffusion of Online Social Networks (OSNs) presents several advantages, like the definition of simple tools for information sharing and spreading. However, OSNs present also some drawbacks, one of the most important one is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs), which decentralize the control of the social network, have been recently proposed to overcome these issues. The decentralization of the control has issued several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To define users’ data allocation strategies, the knowledge of the structure of the ego network and of the user’ temporal…
