Some Investigations on Similarity Measures Based on Absent Words

2019

In this paper we investigate similarity measures based on minimal absent words, introduced by Chairungsee and Crochemore in [1]. They make use of a length-weighted index on a sample set corresponding to the symmetric difference M(x)ΔM(y) of the minimal absent words M(x) and M(y) of two sequences x and y, respectively. We first propose a variant of this measure by choosing as a sample set a proper subset (x, y) of M(x)ΔM(y), which appears to be more appropriate for distinguishing x and y. From the algebraic point of view, we prove that (x, y) is the base of the ideal generated by M(x)ΔM(y). We then remark that such measures are able to recognize whether the sequences x and y share a common s…

Do Corporative Social Programs Generate Social Capital? A Brazilian Case Study

2013

This study focuses on the promotion of the social capital and the development of a civic community through social commitment networks, and consequently, maintaining local development. The methodological procedure adopted was the case study and, as main technique of data analysis, the content analysis was used. The programs of social responsibility of companies renowned as socially responsible from the region of Serra Gaúcha (south Brazil) were studied, analyzing their contribution to the generation or strengthening of the social capital of the reached communities. As the main result of the study we presented the proposal of a new board of indicators for social projects of private companies …

Sociālo tīklu lietošanas paradumu saistība ar apmierinātību ar dzīvi un sociālo salīdzināšanu

2021

Pētījuma mērķis bija noskaidrot, kādas saistības pastāv starp Instagram lietošanas intensitāti, apmierinātību ar dzīvi un sociālo salīdzināšanu. Datu ievākšanai tika izmantotas trīs aptaujas: Apmierinātības ar dzīvi skala (Satisfaction With Life Scale (SWLS); Diener, Emmons, Larsen, & Griffin, 1985; aptauju adaptējusi Anda Upmane, 2010), Sociālās salīdzināšanas skala (Social Comparison Scale; Allan & Gilbert, 1995; aptauju adaptējusi Liliāna Tamsone, 2015), Instagram lietošanas intensitātes skala (Instagram Intensity Scale (IIS); Kalinina, 2019 – aptauja tika adaptēta šī bakalaura darba ietvaros). Pētījumā piedalījās 102 respondenti (93 sievietes un 9 vīrieši) vecumā no 18 līdz 77 gadiem (M…

Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans

2017

In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…

Listwise Collaborative Filtering

2015

Recently, ranking-oriented collaborative filtering (CF) algorithms have achieved great success in recommender systems. They obtained state-of-the-art performances by estimating a preference ranking of items for each user rather than estimating the absolute ratings on unrated items (as conventional rating-oriented CF algorithms do). In this paper, we propose a new ranking-oriented CF algorithm, called ListCF. Following the memory-based CF framework, ListCF directly predicts a total order of items for each user based on similar users' probability distributions over permutations of the items, and thus differs from previous ranking-oriented memory-based CF algorithms that focus on predicting th…

Mehr als Musik: Die sieben Dimensionen des Eurovision Song Contests

2008

"Der Eurovision Song Contest (ESC) ist der weltweit größte internationale Wettbewerb für populäre Musik und das erfolgreichste Fernsehunterhaltungsprogramm in Europa. Obwohl der ESC ursprünglich das Ziel verfolgte, die Entstehung neuer Lieder zu fördern, handelte es sich doch stets um ein von den Fernsehanstalten inszeniertes Medienereignis, das erst nachrangig musikökonomischen Zwecken dient. Für das Publikum ist der ESC auf Grund seiner Periodizität, seiner spezifischen Programmstruktur und nicht zuletzt des Zugehörigkeitsgefühls der Zuschauer, das auf Schemata nationaler und kultureller Identifikation beruht, zu einem hochgradig ritualisierten Medienereignis geworden. Seine Bedeutung geh…

Trends in perceived school stress among adolescentsin five Nordic countries 2002–2014

2019

Abstract Associations between school-related stress and poor health, risk behaviours and low well-being are well documented. The aim of this paper was to estimate trends of perceived school stress experienced by boys and girls of different ages in the Nordic countries, and to describe trends in school stress between the Nordic countries. Nordic data from the Health Behaviour in School-aged Children study (HBSC) between 2002 and 2014 were used. The participants were aged 11–16 years. School stress was measured by a single item; “How pressured do you feel by schoolwork?” The participants answering “some” or “a lot” were categorised as reporting school stress.   Sweden, Norway and Denmark had …

Positive solutions for nonlinear Robin problems

2017

We consider a parametric Robin problem driven by the p-Laplacian with an indefinite potential and with a superlinear reaction term which does not satisfy the Ambrosetti-Rabinowitz condition. We look for positive solutions. We prove a bifurcation-type theorem describing the nonexistence, existence and multiplicity of positive solutions as the parameter varies. We also show the existence of a minimal positive solution $\tilde{u}_\lambda$ and establish the monotonicity and continuity of the map $\lambda\to \tilde{u}_\lambda$.

Automatic evaluation of information provider reliability and expertise

2013

Published version of an article in the journal: World Wide Web. Also available from the publisher at: http://dx.doi.org/10.1007/s11280-013-0249-x Q&A social media have gained a lot of attention during the recent years. People rely on these sites to obtain information due to a number of advantages they offer as compared to conventional sources of knowledge (e.g., asynchronous and convenient access). However, for the same question one may find highly contradicting answers, causing an ambiguity with respect to the correct information. This can be attributed to the presence of unreliable and/or non-expert users. These two attributes (reliability and expertise) significantly affect the quality o…
