A Self-Contained Biometric Sensor for Ubiquitous Authentication
2007
This paper describes a real-life behavior framework in simulation game based on Probabilistic State Machine (PSM) with Gaussian random distribution. According to the dynamic environment information, NPC can generate behavior planning autonomously associated with defined FSM. After planning process, we illuminate Gaussian probabilistic function for real-life action simulation in time and spatial domains. The expected value of distribution is estimated during behavior planning process and variance is determined by NPC personality in order to realize real life behavior simulation. We experiment the framework and Gaussian PSM on a restaurant simulation game. Furthermore we give some suggestions…
Investigating serendipity in recommender systems based on real user feedback
2018
Over the past several years, research in recommender systems has emphasized the importance of serendipity, but there is still no consensus on the definition of this concept and whether serendipitous items should be recommended is still not a well-addressed question. According to the most common definition, serendipity consists of three components: relevance, novelty and unexpectedness, where each component has multiple variations. In this paper, we looked at eight different definitions of serendipity and asked users how they perceived them in the context of movie recommendations. We surveyed 475 users of the movie recommender system, MovieLens regarding 2146 movies in total and compared tho…
A Serendipity-Oriented Greedy Algorithm for Recommendations
2017
Most recommender systems suggest items to a user that are popular among all users and similar to items the user usually consumes. As a result, a user receives recommendations that she/he is already familiar with or would find anyway, leading to low satisfaction. To overcome this problem, a recommender system should suggest novel, relevant and unexpected, i.e. serendipitous items. In this paper, we propose a serendipity-oriented algorithm, which improves serendipity through feature diversification and helps overcome the overspecialization problem. To evaluate our algorithm and compare it with others, we employ a serendipity metric that captures each component of serendipity, unlike the most …
Drivers’ experiences during floods: Investigating the psychological influences underpinning decisions to avoid driving through floodwater
2018
Abstract A major risk factor for many flood-related drownings is driving through floodwater. We aimed to understand Australian drivers’ experiences and beliefs with respect to avoid driving through floodwater using the theory of planned behaviour as a framework. Study 1 (N = 23) used a qualitative design to gain an in-depth understanding of individuals’ experiences with driving through floodwater. Study 2 (N = 157) used a survey-based design to identify the factors related to this behaviour including knowledge, beliefs, and social-cognitive factors. In Study 1, drivers identified a range of advantages (e.g., didn’t damage car), disadvantages (e.g., inconvenient, but not so terrible), barrie…
The (im)possible success of disadvantaged students. Reflections on education, migration and social change
2019
The paper focuses on the ?unexpected pathways? of successful students with an immigrant background: these biographical routes, that seems socially impossible, raise theoretical issues around the individual-society, actor-structure relationship. Disadvantaged students who succeed represent a sociological challenge in the attempt to understand atypical situations and to identify the institutional processes and the structural opportunities that facilitate them, reducing ethnic inequalities in education. This framework is the starting point of the Su.Per. project (Success in educational pathways of students with immigrant background), based on the collection of written autobiographies of 65 imm…
Specific Emotional Reactions to Tonal Music - Indication of the Adaptive Character of Tonality Recognition
2013
People report that specific emotional reactions accompany the perception of tonal relations during listening to tonal music. These reactions are not restricted only to people living in the Western culture. Different types of tonality which are observed in all musical cultures seem to evoke similarly strong emotional reactions. The emotional response to a tonal sound sequence has been predominantly explained by fulfilling or not the pitch-related expectations of listeners. However, although this model indicates the general mechanism of prediction as the main source of an emotional reaction, it does not explain why the musical pitch-related expectation causes a stronger emotional reaction tha…
New is not always costly: evidence from online processing of topic and contrast in Japanese.
2013
Two visual ERP experiments were conducted to investigate topic and contrast assigned by various cues such as discourse context, sentential position and marker during referential processing in Japanese. Experiment 1 showed that there was no N400-difference for new vs. given noun phrases (NPs) when the new NP was expected (contrastively focused) based on its preceding context and sentential position. Experiment 2 further revealed that the N400 for new NPs can be modulated by the NP’s contrastive meaning (exhausitivity) induced from the marker. Both experiments also showed that new NPs engendered an increased Late Positivity. The reduced N400 for new vs. given supports an expectation-based lin…
User expectations, use experiences and continued adoption of a mobile secure communication application
2018
The importance of secure communication between employees in enterprises and governmental organizations as well as technologies to support that has increased tremendously over the past years. This study examines the user expectations before and the use experiences during the implementation phase of a mobile secure communication application together with expectation–confirmation and its influence on continued adoption. The study is explorative in nature and empirically based on thematic analysis of qualitative data collected from pilot users of a mobile secure communication application who work in a governmental organization in Finland. The theoretical basis of the study draws from two well-e…
Innovation expectations and patenting in private and public R&D projects
2017
peer-reviewed In this paper, we investigate how the innovation expectations of public financiers are related to realized patents. The analysis is based on a novel dataset of collaborative R&D projects subsidized by the Finnish Agency of Technology and Innovation (Tekes) and the European Regional Development Fund (ERDF) during the period 2000–2004. Innovation expectations are measured using reports submitted by Tekes experts during ex ante assessments of projects. Our probit model results reveal that Tekes’ patent expectations are positively related to realized patents for projects led by private firms (but not by public organizations). For large organizations, Tekes’ innovation expectations…
Losing a Job and (Dis)incentives to Move
2020
Tässä tutkimuksessa tarkastellaan työpaikan menettämisen ja muiden taloudellisten ja ei-taloudellisten kannustimien vaikutuksia alueelliseen muuttoliikkeeseen. Käytämme yhdistettyä työnantaja-työntekijäaineistoa sekä tietoja alueellisista asuntomarkkinoista. Työpaikan menettäneillä tarkoitamme heitä, jotka menettävät työpaikkansa toimipaikan sulkemisen tai joukkoirtisanomisen takia. Työpaikan menetys lisää henkilön muuttoalttiutta noin 80 prosentilla. Työpaikan menettäneet näyttäisivätkin reagoivan taloudellisiin kannustimiin, sillä alhainen oletettu palkkataso ja korkeat asuntojen hinnat alueella ovat yhteydessä lisääntyneeseen muuttoalttiuteen alueelta, josta henkilö on jäänyt työttömäksi…
