In this article we apply the S(M, g)–calculus of L. Hormander and, in particular, results concerning the spectral invariance of the algebra of operators of order zero in ℒ(L2(ℝn)) to study generators of Feller semigroups. The core of the article is the proof of the invertibility of λ Id + P for a strongly elliptic operator P in Ψ(M, g) and suitable weight functions M and metrics g. The proof depends highly on precise estimates of the remainder term in asymptotic expansions of the product symbol in Weyl and Kohn–Nirenberg quantization. Due to the Hille–Yosida–Ray theorem and a theorem of Courrege, the result concerning the invertibility of λ Id + P is applicable to obtain sufficient conditio…

From Togetherness to Equal Partnership in Role Play

1998

In the day care centre, already at the transition stage to role play children show different kinds of participation. They observe each other's play, share goal orientation and directly tutor each other. The play process is materially supported and often initiated by educators. However, children also need to acquire the power to act autonomously in role play. The different kinds of participation in young children's play, as well as the appearance and development of basic features of joint role play were examined in three games of a two‐year‐old girl, Katju, in her day care group. The games are examples of ten play sessions she was involved in. These data were collected by means of reactive p…

Creating Digital Musical Instruments With and for Children: Including Vocal Sketching as a Method for Engaging in Codesign

2020

International audience; A class of master of science students and a group of preschool children codesigned new digital musical instruments based on workshop interviews involving vocal sketching, a method for imitating and portraying sounds. The aim of the study was to explore how the students and children would approach vocal sketching as one of several design methods. The children described musical instruments to the students using vocal sketching and other modalities (verbal, drawing, gestures). The resulting instruments built by the students were showcased at the Swedish Museum of Performing Arts in Stockholm. Although all the children tried vocal sketching during preparatory tasks, few …

What Did CS Students Recognize as Study Difficulties?

2019

Computing education research shows substantive interest in novice programming challenges. The present study was rather interested in any phenomena that students would recognize as difficulties during their university studies. The research question was what computing students recognized as their study difficulties after the first year of study. An inductive thematic analysis was applied to the students’ personal writing of the difficulties experienced. The main result categories were independence in new environment, academic requirements, lack of prospects, learning to work, and social integration, which were illustrated by multiple lower level themes. The results inform educators of the wid…

Searching for the truth about schizophrenia requires the application of similarly high standards of proof to biological and social risk factors

2013

In their provocative paper, Bentall and Varese (2012) criticize our review on child abuse and schizophrenia (Sideli, Mule, La Barbera, & Murray, 2012) and suggest that we have a biological bias whi...

A Robot Architecture Based on Higher Order Perception Loop

2009

The paper discusses the self-consciousness of a robot as based on higher order perceptions of the robot itself. In this sense, the first order perceptions of the robot are the immediate perceptions of the outer world of the robot, while higher order perceptions are the robot perceptions of its own inner world. The resulting architecture based on higher order perceptions has been implemented and tested in a project regarding a robotic touristic guide acting in the Botanical Garden of the University of Palermo.

You are not alone – Social sharing as a necessary addition to the Embracing factor

2017

AbstractI argue that the Embracing factor cannot be adequately conceptualized without taking into account the regulatory power of the social sharing of emotions. Humans tend to share their negative emotions with close others, and they benefit from it. I outline how this mechanism works in art reception by regulating and transforming negative emotions into positive experiences.

Best Practices for International eSourcing of Software Products and Services

2008

This paper analyzes how the information and communications technology-supported international eSourcing of software products and services (IeS) can be effectively executed. The extant literature falls short of providing a systematic and detailed enough set of best practices to guide IeS. This paper presents best practices for IeS to facilitate further research, and to help managers and other stakeholders to understand, execute, and proactively improve and manage international eSourcing. The practices emphasize the need to establish and enact rigorous, mature, and quantitatively managed eSourcing life- cycles in order to transcend temporal, geographical, social, technical, and other boundari…

Explaining Change Paths of Systems and Software Development Practices

2010

This chapter discusses how systems development practices are shaped. Based on interviews conducted in ten development organizations and previous literature, we identify eight types of change paths in systems development practices: emergence, adoption, idealization, formalization, abandonment, informalization, entropy, and disobedience. We argue that the eight change path types provide an integrated theoretical framework on the study of how systems development practices change in organizations, projects, and among individual developers in a given context. We discuss how this framework complements existing theories and concepts of the contemporary literature on systems development.

Editorial: Software language engineering

2008

Software languages play an important role in software development. Software languages are the artificial languages that are used to describe software systems at various abstraction levels. They are applied to describe requirements and designs for software, definitions of software architectures, and implementations of software systems. A huge variety of different technological spaces exist to describe languages: programming languages, software modeling languages, data modeling languages, domain-specific languages, ontology language, and others.
