Modeling Political Corruption in Spain
2021
Political corruption is a universal phenomenon. Even though it is a cross-country reality, its level of intensity and the manner of its effect vary worldwide. In Spain, the demonstrated political corruption cases that have been echoed by the media in recent years for their economic, judicial and social significance are merely the tip of the iceberg as regards a problem hidden by many interested parties, plus the shortage of the means to fight against it. This study models and quantifies the population at risk of committing political corruption in Spain by identifying and quantifying the drivers that explain political corruption. Having quantified the problem, the model allows changes to be …
Mathematics Skills of Kosovar Primary School Children: A Special View on Children with Mathematical Learning Difficulties
2018
The present study examined the development of mathematics skills of Kosovar primary school children in terms of their gender, living area, socio-economic status, and achievement level. A special emphasis was placed on longitudinal investigations of the development of mathemat-ics skills in children with learning difficulties in mathematics over a 2-year and 4-month period. Participants were 553 fourth-graders, 85 of whom identified with mathematical learning difficulties were classified into two subgroups: children with low mathematics achievement and children with limited mathematics ability. Results have shown that there were no gender differences in mathematics achievement. Children’s li…
Best friends in adolescence show similar educational careers in early adulthood
2012
The present study investigated the role of best friends in educational career development from adolescence to adulthood. Participants' (N = 476) reciprocal best friendships were identified at age 15, while their educational attainment was investigated in early adulthood (age 26), their intelligence (IQ) at age 13, and parental education, educational expectations and academic achievement at age 16. The results revealed that adolescent best friends ended up pursuing similar educational careers in adulthood. Furthermore, three kinds of partner-effects were found when adolescents' prior career behaviors were controlled for: (1) best friends' intelligence predicted adolescents' later academic pe…
Students’ Perception of Cell Phones Effect on their Academic Performance: A Latvian and a Middle Eastern University Cases
2021
This study is unique in its attempt to combine the Technology Acceptance Model (TAM) with external variables and the Information System Continuance Theory, in the context of mobile learning. It extends TAM with the external variables perceived mobility and perceived enjoyment. Mainly, students’ perception of cell phones effect on their academic performance is investigated. The study was conducted at two different universities—in Europe and the Middle East. Cell phone usage is analyzed from the perspective of mobile learning. The data in this study were collected from 103 students from the University of Latvia and 106 students from a Middle Eastern private American University. This study sho…
Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
2013
Different spatial distributions of optical vortices have been generated and characterized by implementing arrays of devil's vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the preferred position and topological charge value to each vortex in the structure, tuning the desired angular momentum. Distributions with charges and momenta of the opposite sign have been experimentally demonstrated. The angular velocity exhibited by the phase distribution around the focal plane has been visualized, showing an excellent agreement with the simulations. The practical limits of the method, with interest for applications involving particle transfer and manipula…
Preprinting is positively associated with early career researcher status in ecology and evolution.
2021
Abstract The usage of preprint servers in ecology and evolution is increasing, allowing research to be rapidly disseminated and available through open access at no cost. Early Career Researchers (ECRs) often have limited experience with the peer review process, which can be challenging when trying to build publication records and demonstrate research ability for funding opportunities, scholarships, grants, or faculty positions. ECRs face different challenges relative to researchers with permanent positions and established research programs. These challenges might also vary according to institution size and country, which are factors associated with the availability of funding for open acces…
La inserción laboral de los inmigrantes italianos en Valencia durante la crisis
2018
España ha pasado de una fase de intensa inmigración internacional durante el período de crecimiento económico a otra de re-emigración y retornos de extranjeros (y de emigración de nativos) durante la recesión. En nuestra investigación hemos observado una tendencia opuesta: durante la crisis se ha incrementado significativamente la llegada de inmigrantes procedentes de Italia a la ciudad de Valencia. Se trata de personas económicamente activas, con intención de permanencia, cualificadas y procedentes de regiones con indicadores socioeconómicos superiores a los de la Comunidad Valenciana. Por consiguiente, el análisis de su inserción laboral es clave para explicar las causas de la migración. …
Scientific communication or a qualification for an academic career? What use is publishing papers in psychology journals?
2018
[ES]: Este trabajo analiza todas las revistas de psicología que se hallan incluidas en las diversas categorías de las bases de datos JCR (SCI y SSCI) y SJR durante el periodo 2014-2016 para tratar de identificar las revistas que se encuentran mejor posicionadas en esta disciplina, sus especialidades y los países con mayor número de publicaciones indexados en dichas bases de datos. [Método]: Se analizó la distribución de revistas por países, cuartil y categoría para determinar la posición de las revistas en cada país e identificar los que tuviesen mayor cantidad de revistas de excelencia en psicología en la escena internacional. [Resultados]: Estados Unidos y Reino Unido tienen el mayor núme…
Kohti valveutumista ja ajattelun rajoja kriittisen pedagogiikan keinoilla
2018
Katsauksessa pohdimme kriittisen pedagogiikan mahdollisuuksia lisätä opettajaopiskelijoiden kykyä jäsentää yhteiskunnallisten ilmiöiden suhdetta kasvatukseen. Esimerkkinä käytämme Lapset elämänsä valtiaiksi -hanketta, jota Tampereen ammattikorkeakoulun sosionomikoulutuksessa on toteutettu Venäjällä ja Virossa. Siinä sosiokulttuurisen innostamisen avulla, opiskelijoiden oman osallistumisen kautta, pyritään luomaan solidaarisuuteen ja tasa-arvoon kurkottavia yksilöitä. Toiminnan keskeisiä arvoja ovat yhteisöllisyys, osallistuminen, dialogi ja luovuus. Prosessin päämääränä on todellisuuden kriittinen tarkastelu ja siitä kumpuava toiminta. Kriittisen pedagogiikan sovelluksia toteutetaan yliopis…
Does School Matter?
2008
School burnout can be defined as consisting of exhaustion due to school demands, cynical, and detached attitude toward one’s school, and feelings of inadequacy as a student ( Kiuru, Aunola, Nurmi, Leskinen, & Salmela-Aro, 2008 ; Salmela-Aro & Näätänen, 2005 ; Schaufeli, Martínez, Pinto, Salanova, & Bakker, 2002 ). The first aim of the present study was to examine the extent to which schools differ in school-related burnout. Moreover, the aim was to examine the extent to which school-related and background factors are associated with school burnout at the school level and at the individual level. The participants were 58,657 students from 431 comprehensive schools and 29,515 stu…
