Cyber security exercise : Literature review to pedagogical methodology

2019

This paper is a literature review, where we try to find out pedagogical principles has used in different virtual or simulated industry learning environments. The purpose is to use these findings to create in the future a new model for teaching in cyber security exercises. Cyber security exercises are the major service at JYVSECTEC - Jyväskylä Security Technology, cyber security research, training and development center in Finland [1]. JYVSECTEC Cyber security exercises are executed in real life simulation environment, RGCE (Realistic Global Cyber Environment) [1]. It provides the same functionality as the real Internet, but it is isolated from the real Internet and fully controlled by JYVSE…

A Complete, Exact and Efficient Implementation for Computing the Edge-Adjacency Graph of an Arrangement of Quadrics

2011

International audience; We present a complete, exact and efficient implementation to compute the edge-adjacency graph of an arrangement of quadrics, i.e. surfaces of algebraic degree 2. This is a major step towards the computation of the full 3D arrangement. We enhanced an implementation for an exact parameterization of the intersection curves of two quadrics, such that we can compute the exact parameter value for intersection points and from that the edge-adjacency graph of the arrangement. Our implementation is complete in the sense that it can handle all kinds of inputs including all degenerate ones, i.e. singularities or tangential intersection points. It is exact in that it always comp…

Precio no monetario percibido en alojamientos e-peer-to-peer. La perspectiva de los huéspedes de Airbnb

2021

[EN] Price is considered as a key variable in predicting buying behavior. However, few studies have focused on how non-monetary price is affected and can affect other components of the consumer endogenous variables. This paper seeks (1) to analyze the effects of antecedents of behavioural price (past experience, the benefits and risks of peer to peer accommodation services) on the guest perceived price, and (2) to determine the effect of this price and past experience on guest intentions. With a sample of 136 Airbnb guests and the use of SEM, results show that past experience, financial risk, and time risk influence the non-monetary perceived price. This price and past experience affect gue…

Usage activity, perceived usefulness, and satisfaction in a web-based acceptance and commitment therapy program among Finnish ninth-grade adolescents.

2020

Understanding adolescent usage activity and experiences in web-based psychological intervention programs helps in developing universal programs that can be adopted for promotion of adolescent well-being and prevention of mental health problems. This study examined the usage activity, perceived usefulness (i.e., learning of mindfulness, acceptance and value-related skills), and program satisfaction of 157 Finnish ninth-grade adolescents, who participated in a school-based five-week universal acceptance and commitment therapy web intervention called Youth Compass. Individual and growth environment-related antecedents were measured before the five-week intervention, adolescents' usage activity…

Digital resources in the current journalistic narrative: Uses and limitations of hypertext, multimedia and interactivity

2020

Characterised by its multilingual and multiformat features, the multimedia journalism narrative is shaping a new ‘archaeology of composition’ (Manovich, 2005), also called the ‘new textuality’ (Anichini, 2003). As digital media celebrates its 25th anniversary (Salaverría, 2019), this research aims to examine the current state of the multimedia narrative in journalism. The defining elements of this narrative in the generalist information media have been analysed through the observation of hypertextual, multimedia and interactive resources. The methodology used is content analysis, allowing for both the systemization and description of the predominant parameters through the comparative study …

On Prefix Normal Words

2011

We present a new class of binary words: the prefix normal words. They are defined by the property that for any given length $k$, no factor of length $k$ has more $a$'s than the prefix of the same length. These words arise in the context of indexing for jumbled pattern matching (a.k.a. permutation matching or Parikh vector matching), where the aim is to decide whether a string has a factor with a given multiplicity of characters, i.e., with a given Parikh vector. Using prefix normal words, we give the first non-trivial characterization of binary words having the same set of Parikh vectors of factors. We prove that the language of prefix normal words is not context-free and is strictly contai…

Evaluation de la pertinence dans un système de recommandation sémantique de nouvelles économiques

2014

Today in the commercial and financial sectors, staying informed about economic news is crucial and involves targeting good articles to read, because the huge amount of information. To address this problem, we propose an innovative article recommendation system, based on the integration of a semantic description of articles and on a knowledge ontological model. We support our recommendation system on an intrinsically efficient vector model that we have perfected to overcome the confusion existing in models between the concepts of similarity and relevancy that does not take into account the effects of the difference in the accuracy of the semantic descriptions precision between profiles and a…

Tasapainoilua kurinalaisuuden ja tarkoituksenmukaisuuden välillä : oppilaiden ei-toivottuun käyttäytymiseen liittyvän ongelmanratkaisun kehittäminen …

1999

This qualitative study explores the problem-solving culture associated with students' challenging behavior in an upper comprehensive school (ages 13 to 16). Based on the findings, new possibilities are suggested for developing the problem­- solving culture in the Comprehensive School. The data consist of interviews, written stories by the participants, videotapes of the student welfare team mee­tings, official documents, and open answers to a questionnaire. Data were gathered from teachers, other school personnel, students, and students' parents. Data were organized around four themes: (1)definition of the situation, (2)sense of community, (3)social control, and (4)dealing with the student'…

Pandemianaikaista kielipedagogiikkaa : näkökulmia maahanmuuttajien etäopetukseen

2020

The novel coronavirus pandemic forced schools to implement remote instruction during spring 2020. I studied teachers’ perceptions of the implementation of newcomer and Finnish as a second language instruction during the remote period. Survey respondents considered remote instruction a burden on both students and teachers and thought students’ unfamiliarity with educational technology presented challenges. Benefits of remote instruction included students’ increased self-directedness in learning, the use of technologies for differentiation, and an increase in collaboration with colleagues and families. nonPeerReviewed
