Research Note: Reciprocal Effects of Negative Press Reports

2007

A B S T R A C T ■ The influence of negative press reports on their subjects was determined by means of a questionnaire answered by 91 persons who had complained about such reports to the Deutsche Presserat (German Press Council). The findings show that negative press reports have long-lasting emotional and social consequences, as perceived by the subjects. Plausible interactions exist between these consequences. There is a theoretical basis for attributing both types of consequences to certain characteristics of the reports. ■

Social Animation in Complex Environments

2007

This work presents a market-based social model to produce good quality behavioral animations for groups of intelligent virtual agents. The social model coordinates the activities of groups of virtual characters and also includes social actions in the agent decision-making. We follow the Multi-Agent Resource Allocation approach presented in [2], where agents express their preferences using utility functions. The dynamics of social interactions is inspired by the theory of Piaget [3] over which we have implemented reciprocal task exchanges.

Postattack deimatic display in the mountain katydid, Acripeza reticulata

2015

Prey use many strategies to avoid being detected by their predators. However, once detected and identified as potentially palatable, prey must employ a second line of defence such as performing a deimatic (startle) display. During the predation sequence, composed of the stages encounter, detection, identification, approach, subjugation and consumption, such defences should be deployed as the predator approaches, but before prey are brought under the predator's control (i.e. before subjugation). We tested this assumption in the mountain katydid (or bush cricket), which is cryptic at rest, but when disturbed flashes spectacular abdominal colours by lifting its wings, and is chemically defende…

La comunità come rete di relazioni reciproche: percorsi collaborativi nella formazione iniziale degli insegnanti di sostegno

2017

Communities of practice can become a perfect place where teachers can reflect on their practice, share approaches, experiment with new content and new practices. The interaction between teachers in a community of practice encourages peer learning and stimulates problem solving. The present work, centered on the reciprocal teaching and project based learning methodologies, involved 195 disability and inclusion pre-service teachers and gave them the opportunity to experience the integration of the two teaching / learning models through which they learned how to collaborate and achieve results in effective way and working with others.

Pictorial meaning-making in a community project in Helsinki. Freirean interpretations of a dialogical process

2018

Participation in public discourse belongs to a democratic citizenship. However, part of the population is excluded from such communal discussion. This paper describes how the photography group Camera Obs., which principally contained unemployed people in Helsinki, created pictorial voices from their own everyday experiences through a dialogical process, rendering them also visible to other people. The research focuses on the group’s activity during the years 2004–6, from the beginning of the project to its first exhibition. As a theoretical background, Paulo Freire’s ideas of dialogue and voice creation, combined with Vygotsky’s and Mezirow’s concept of meaning-making, have been applied. T…

Reading Comprehension and Working Memory's Executive Processes: An Intervention Study in Primary School Students

2013

ABSTRA C T Reading comprehension is a highly demanding task that involves the simultaneous process of extracting and constructing meaning in which working memory’s executive processes play a crucial role. In this article, a training program on working memory’s executive processes to improve reading comprehension is presented and empirically tested in two experiments with third-grade primary school students. Experiment 1 showed a greater gain after training the experimental group in contrast to the control group in reading comprehension and intelligence. In experiment 2, we focused on the training processes and compared training results of high and low pretest reading comprehension groups. R…

Exploring parallel capabilities of an innovative numerical method for recovering image velocity vectors field

2010

In this paper an efficient method devoted to estimate the velocity vectors field is investigated. The method is based on a quasi-interpolant operator and involves a large amount of computation. The operations characterizing the computational scheme are ideal for parallel processing because they are local, regular and repetitive. Therefore, the spatial parallelism of the process is studied to rapidly proceed in the computation on distributed multiprocessor systems. The process has shown to be synchronous, with good task balancing and requiring a small amount of data transfer.

Multiprocessor SoC Implementation of Neural Network Training on FPGA

2008

Software implementations of artificial neural networks (ANNs) and their training on a sequential processor are inefficient because they do not take advantage of parallelism. ASIC and FPGA implementations employ specific hardware structures to exploit parallelism in order to improve processing speed; however, optimizing resource usage requires the use of fixed-point arithmetic, thereby losing precision, and the final system is restricted to a particular network topology. This paper presents a mixed approach based on a multiprocessor system-on-chip (SoC) on a FPGA. The use of software-driven embedded microprocessors with custom floating-point extensions for ANN related functions allows for gr…

SoC-Based Implementation of the Backpropagation Algorithm for MLP

2008

The backpropagation algorithm used for the training of multilayer perceptrons (MLPs) has a high degree of parallelism and is therefore well-suited for hardware implementation on an ASIC or FPGA. However, most implementations are lacking in generality of application, either by limiting the range of trainable network topologies or by resorting to fixed-point arithmetic to increase processing speed. We propose a parallel backpropagation implementation on a multiprocessor system-on-chip (SoC) with a large number of independent floating-point processing units, controlled by software running on embedded processors in order to allow flexibility in the selection of the network topology to be traine…
