Becoming a Language Teacher: A dream come true or a source of anxiety?
2015
In this qualitative study the author examined personal narratives written by 14 Finnish speaking student teachers of Swedish, in order to find out what they tell about their thoughts and feelings concerning their future work as language teachers. The following three themes were in focus: firstly, what university students tell about their reasons for wanting to become teachers in the first place; secondly, what kinds of worries concerning their future work they mention in their narratives; and thirdly, how student teachers could be supported during transition from teacher education to teaching. According to the study, students choose teaching for reasons that are related to: (a) teacher iden…
Peripersonal Visuospatial Abilities in Williams Syndrome Analyzed by a Table Radial Arm Maze Task
2020
Williams syndrome (WS) is a genetic deletion syndrome characterized by severe visuospatial deficits affecting spatial exploration and navigation abilities in extra-personal space.To date, little is known about spatial elaboration and reaching abilities in the peripersonal space in individuals with WS. The present study is aimed at evaluating the visuospatial abilities in individuals with WS and comparing their performances with those of mental age-matched typically developing (TD) children by using a highly sensitive ecological version of the Radial Arm Maze (table RAM). We evaluated 15 individuals with WS and 15 TD children in two different table RAM paradigms: the free-choice paradigm, ma…

Need for closure moderates the break in the message effect
2016
Abstract Cutting the message into smaller portions is a common practice in the media. Typically such messages consist of a headline followed by a story elaboration. In a series of studies Dolinski and Kofta (2001) have shown that such a break in the message increases the effect of the information provided in the headline over that of a story which actually contained information inconsistent with that headline. A possible explanation of this effect, based on the concept of the need for cognitive closure, is presented in the article. The experiment shows the break-in-the-message effect is found mainly for participants with high need for closure but not for those with low such need.
A novel technique for opus vermiculatum mosaic rendering
2006
In this paper we present a method to generate a digital mosaic starting from a raster input image. Mosaics generation of artistic quality is challenging. The basic elements, the tiles, typically small polygons, must be packed tightly, emphasizing orientations chosen by the artist. An adhoc boundaries detection have to be performed according to the directional guidelines. Different mosaic styles can be automatically rendered, depending on artistic techniques considered (“opus musivum”, “opus vermiculatum”, etc.). The proposed method is able to reproduce the colors of the original image emphasizing relevant boundaries by placing tiles along their direction. The boundaries detection is based o…

Fractalkine Signaling and Microglia Functions in the Developing Brain.
2015
Microglial cells are the resident macrophages of the central nervous system (CNS). Besides their classical roles in pathological conditions, these immune cells also dynamically interact with neurons and influence their structure and function in physiological conditions. The neuronal chemokine fractalkine and its microglial receptor CX3CR1 are one important signaling pathway involved in these reciprocal interactions. In the present review, we will discuss recent evidence indicating that fractalkine signaling also determines several functions of microglial cells during normal CNS development. It has been known for a decade that microglial cells influence the neuronal death that normally occur…
Energy efficient resource allocation in heterogeneous software defined network: A reverse combinatorial auction approach
2015
In this paper, resource allocation for energy effi- ciency in heterogeneous Software Defined Network (SDN) with multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse combinatorial auction game, which takes different quality of service (QoS) requirements into account. The heterogeneous network selection associated with power allocation problem is optimized by maximizing the energy efficiency of data transmission. By exploiting the properties of fractional programming, the resulting non-convex Winner Determination Problem (WDP) is transformed into an equivalent subtractive convex optimization problem. The proposed reverse combinatorial auction ga…
Benefits and drawbacks of communication visibility : from vicarious learning and supplemental work to knowledge reuse and overload
2022
Purpose This study aims to examine some of the benefits and drawbacks of communication visibility. Specifically, building on communication visibility theory, the authors study how and why message transparency and network translucence may increase knowledge reuse and perceived overload through behavioral responses of vicarious learning and technology-assisted supplemental work. Design/methodology/approach Drawing on survey data obtained from 1,127 employees of a global company operating in the industrial machinery sector, the authors used structural equation modeling to test the hypothesized model. Findings The results demonstrate that the two aspects of communication visibility yield somew…
