Qualitative Comparison of Community Detection Algorithms
2011
Community detection is a very active field in complex networks analysis, consisting in identifying groups of nodes more densely interconnected relatively to the rest of the network. The existing algorithms are usually tested and compared on real-world and artificial networks, their performance being assessed through some partition similarity measure. However, artificial networks realism can be questioned, and the appropriateness of those measures is not obvious. In this study, we take advantage of recent advances concerning the characterization of community structures to tackle these questions. We first generate networks thanks to the most realistic model available to date. Their analysis r…
Avoiding strange attractors in efficient parametric families of iterative methods for solving nonlinear problems
2019
[EN] Searching zeros of nonlinear functions often employs iterative procedures. In this paper, we construct several families of iterative methods with memory from one without memory, that is, we have increased the order of convergence without adding new functional evaluations. The main aim of this manuscript yields in the advantage that the use of real multidimensional dynamics gives us to decide among the different classes designed and, afterwards, to select its most stable members. Moreover, we have found some elements of the family whose behavior includes strange attractors of different kinds that must be avoided in practice. In this sense, Feigenbaum diagrams have resulted an extremely …
Clinical Behavior of Short Dental Implants: Systematic Review and Meta-Analysis
2020
Short implants are an increasingly common alternative to other surgical techniques in areas where bone availability is reduced. Despite the advantages they offer, a variety of biological repercussions have been described in the literature that can even lead to the loss of these. The aim of this systematic review and meta-analysis was to analyze the impact of the use of short implants on their survival and on peri-implant bone loss, evaluating the influence that length, diameter, and crown-to-implant ratio (C/I) have on these parameters. This systematic review was based on guidelines proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An electronic se…
Qualitative Analysis of Feed Management Practice on Goat Herds by Self Organizing Maps in Murcia Region of Spain
2007
Abstract Fernandez, C., Soria, E., Magdalena, R., Martin, J.D. and Mata, C. 2007. Qualitative analysis of feed management practice on goat herds by self organizing maps in Murcia region of Spain. J. Appl. Anim. Res., 32: 41–47. Self organizing maps (SOM) were used to analyze data from ninety four herds. Data were obtained from surveys and management practices were evaluated. The 18% of farms were dairy goat farms with milking machines, with a herd size of 100 to 200 goats and most of these bought compound feed. 12% has the same characteristics but farmers prepared their own diet. 16% were similar to previous prototypes, but farmers in addition to dairy goat production kept sheep as well. 23…
(Un)sustainable creativity? Different manager-employee perspectives in the finnish technology sector
2020
The importance of creativity for working life and in organizations has increased in recent years. At the same time, the theme of sustainability has been intensely debated in research, society, and organizations. Together, creativity and sustainability have sometimes been described as a contradictory phenomenon: they are described in ways that place them in opposition to each other. To better understand creativity and sustainability and their differences from the perspective of people in different positions, we take advantage of a sociocultural approach in which we do not focus only on creative individuals but also on the impact of creativity on both organizational stakeholders and society a…
¿Qué dicen los adolescentes sobre el acoso escolar?
2019
Resumen: Todos los actos antisociales, incluidos la violencia y el acoso escolar, lo son dentro de la colectividad en la que se producen y son reflejo de esa colectividad. Este estudio se centra en el discurso espontáneo de 406 adolescentes entre 15 y 21 años sobre el acoso escolar. El análisis cualitativo de los datos permite inferir cuatro principios discursivos que se articulan desde la inicial negación de la violencia (“eso no pasa”), a la negación de la responsabilidad (“si pasa, no soy yo, somos todos”), la negación de la gravedad (“si es broma, no hace daño), y la atribución a la víctima (el acoso tiene más que ver con la víctima que con el agresor). El análisis del discurso espontán…
In the shadow of threatening norms: How students with visual impairment contest and reproduce institutional positions
2020
This article focuses on semi-narrative guided interviews with students with visual impairment (VI) who attend a state-approved special school for students with VI at the time of the interview, although they had different previous experiences in both segregated and inclusive schools. We are conducting a qualitative analysis from the perspective of teenagers concerning how they negotiate institutional ascriptions of (dis)abilities. We have selected interview sequences of two young people: (a) Kai: self-confidence and internalized self-doubt and (b) Felix: between fighting and claiming ableist divides. Our analyses reveal the different ways of how Kai and Felix each contest the ableist divide…
Sociocultural Factors and Female Entrepreneurship in the Innovative Service Sector in Catalonia: A Qualitative Analysis
2013
The purpose of this chapter is to analyse the main sociocultural factors and their impact on female entrepreneurship in the innovative service sector in Catalonia (Spain) and to establish differences to male initiatives using the institutional approach as a theoretical framework. Based on a comparative case study, the principal findings suggest that social networks, role models, entrepreneurial attitudes and family context are important determinants of female entrepreneurship. Family context is, in particular, a crucial factor, which might have a larger impact on women than men. The research contributes both theoretically, with the creation of knowledge in less researched areas such as fema…
Clinical Behavior of Ceramic, Hybrid and Composite Onlays. A Systematic Review and Meta-Analysis
2020
A systematic review and meta-analysis was performed to analyze the survival of onlay restorations in the posterior region, their clinical behavior according to the material used (ceramic reinforced with lithium disilicate, conventional feldspathic ceramic or reinforced with leucite; hybrid materials and composite), possible complications, and the factors influencing restoration success. The systematic review was based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, without publication date or language restrictions. An electronic search was made in the PubMed, Scopus, Embase, and Cochrane databases. After discarding duplicate publications and stu…
"I ate an apple today" : suitability of Facebook posts and reactions to norm violations
2015
Facebook on yksi maailman suosituimmista sosiaalisista verkostoitumissivuista. Käyttäjät esiintyvät Facebookissa pääsääntöisesti omilla nimillään, kirjoittavat lyhyitä tekstejä verkostolleen ja jakavat muuta materiaalia avoimesti. Facebookia ja sosiaalista mediaa on tutkittu paljon erilaisista näkökulmista, mutta Facebookiin kirjoituksen aiheista ei ole paljoa tutkimusta. Tämän tutkimuksen tarkoituksena on selvittää mistä aiheista ihmiset kirjoitavat Facebookiin, mitä aiheita välttävät, mitä aiheita pitävät täysin sopimattomina ja miten he reagoivat epäsopiviin kirjoituksiin. Näitä kysymyksiä varten suoritettiin verkko-kysely, jossa kysyttiin avoimesti vastauksia näihin kysymyksiin. Vastaaj…
