Experiencias psicóticas atenuadas y consumo de cannabis en adolescentes de la población general
2019
El propósito de este estudio fue analizar la relación entre las experiencias psicóticas atenuadas y el consumo de cannabis en una muestra representativa de adolescentes de la población general. Un total de 1,588 estudiantes (M=16,13 años; DT = 1,36), 739 eran hombres (46,5%), pertenecientes a 34 escuelas y 98 aulas, seleccionados mediante muestreo aleatorio estratificado por conglomerados, fueron encuestados. Los instrumentos administrados fueron el Cuestionario de Pródromos de Psicosis-Breve, el Cuestionario de Capacidades y Dificultades, el Cuestionario de Consumo de Sustancias Modificado, el Penn Matrix Reasoning Test (PMRT), la Family Affluence Scale-II y la Escala Oviedo de Infrecuenci…
Ecological study of the wood mouse helminth community in a burned Mediterranean ecosystem in regeneration five years after a wildfire
2007
AbstractParasites are used as biological tags in environmental impact studies. However, terrestrial systems in general and small mammals in particular are rarely considered in these ecological studies. Based on the effects of a wildfire which occurred in the Spanish Serra Calderona Natural Park — a typical Mediterranean ecosystem — the regeneration process of the wood mouse population and its helminth community is analysed. A total of 217 individuals of Apodemus sylvaticus were studied in a five year period, from the second to the fifth post-fire year: 152 mice originating from the burned area and 65 from the control — non-burned — area. The helminth community for both burned and non-burned…
Preliminary health screening and possible pathogen determination in aBufo bufo(Linnaeus, 1758) (Amphibia: Bufonidae) population
2010
The population of the common toad, Bufo bufo, on Jersey (Channel Islands, UK) has undergone a marked decline over recent years. Hypothesized causes for this decline include land use change, pollution, climate change and predation. We examined the carcasses of 97 wild adult common toads for gastrointestinal and pulmonary helminths. In addition, 31 adult toad carcasses were examined for the presence of ranavirus infection, and 212 wild common toads were examined for the presence of infection with the fungus Batrachochytrium dendrobatidis. Three nematode species Rhabdias bufonis, Aplectana macintoshii and Oswaldocruzia filiformis, and one species of cestode, Nematotaenia dispar, were identifie…
Why Do Players Misuse Emotes in Hearthstone? : Negotiating the Use of Communicative Affordances in an Online Multiplayer Game
2018
This paper examines player-to-player interaction in Hearthstone: Heroes of Warcraft (Blizzard Entertainment, 2004). The game designers have attempted to limit what they see as negative interaction by forcibly limiting player-to-player social interaction. Based on an analysis of forum discussions, this empirical study illustrates how players utilize Hearthstone's restricted communication affordances for negative and insulting purposes, and how players negotiate their shared symbolic reality concerning this type of interaction, labeled "Bad Manner(s)" or "BM". The continuous debate over an issue which ultimately cannot be solved shows that players care deeply about the game and the surroundin…
SCI Brief Form (SCI-BF): Psychometric and Factor Structure Analyses in Argentina
2018
Resumen El estudio de las virtudes y fortalezas del carácter es uno de los temas más importantes dentro de la psicología positiva. Peterson y Seligman (2004) determinaron que 24 fortalezas del carácter estaban vinculadas a 6 virtudes y llamaron VIA a esa clasificación. Nuestro trabajo está incluido en la investigación sobre esa clasificación. Se desarrolló un instrumento de medición de 24 ítems de autopuntuación global directa para evaluar las 24 fortalezas del carácter de la clasificación de Peterson y Seligman (2004). Este instrumento es la versión corta del IVyF. Se analizaron las características psicométricas de este instrumento llamado IVyF abreviado (IVyFabre; Strength of Character In…
Serving for state and industry by doing nothing but practice and play : Football shamateurism in East Germany, Hungary and Romania
2022
This presentation aims at discussing the opportunities and limitations of football players in East Germany, Hungary and Romania in the period between the end of World War II (1945) and the collapse of the Eastern bloc (1989). Football served as an important propaganda tool for the communist regimes in Eastern Europe. Therefore, the political elites supported football players financially with sinecures in the military, police, and in commercial and industrial companies, as well as by releasing them for training and competitions in their associated clubs. Their status as “shamateurs” granted them privileges in socialist societies over common people but also limited their possibilities to deve…
Changes in Family Income around the Time of Birth of Children in Germany between 1985 and 2004
2010
Während der Verlauf und die Ursachen des Geburtenverhaltens intensiv erforscht wurden, sind die finanziellen Folgen einer Geburt empirisch kaum beachtet worden. Daher werden hier kurzfristige Wohlstandsveränderungen von Familien (hinsichtlich verfügbarem Haushaltseinkommen und Äquivalenzeinkommen) rund um die Geburt eines Kindes in längsschnittlicher Perspektive analysiert und auf ihre Ursachen untersucht. Zu diesem Zweck wurden die Daten des Sozio-oekonomischen Panels (1984-2005) mittels Fixed-Effekt-Panelregressionsmodellen analysiert. Als Ergebnis kann festgehalten werden, dass die finanziellen Folgen einer Geburt in den letzten Jahren deutlich gewachsen sind und vor allem das erste Kind…
The heterogeneity of the Mexican lithospheric mantle: Clues from noble gas and CO2 isotopes in fluid inclusions
2022
The abundance of mantle-derived rocks and lavas, in combination with its tectonic evolution, render Mexico a perfect laboratory to investigate the chemical and the isotopic heterogeneity of the lithospheric mantle. New data on the composition of noble gases and CO2in Mexican mantle xenoliths and lavas is reported. Our samples consist of six ultramafic nodules from the Durango Volcanic Field (DVF) and the San Quintin Volcanic Field (SQVF), monogenetic complexes belonging to the Mexican Basin and Range province; and four lavas from the Sierra Chichinautzin (SCN), a Quaternary monogenetic volcanic field located in the Mexican volcanic arc. Ne and Ar isotopes in fluid inclusions reveal mixing b…
Type of Delivery, Neuropsychological Development and Intelligence in Twin Births
2019
Based on a retrospective cohort design with six-year-old children born in twin births, the relationship between verbal, non-verbal, global neuropsychological development, general intelligence and type of delivery has been studied. To this end, the possible effect of third gestational, obstetric and neonatal variables, such as maternal age at delivery, fetal presentation, gestational age, newborn weight and Apgar at minute one, was controlled. The exposed cohort includes children born by cesarean section, and the unexposed cohort is composed of children born vaginally with or without induction. A total of 124 children were evaluated in their first year of primary school using the Child Neuro…
Parasitoids (Hymenoptera) of leaf-spinning moths (Lepidoptera) feeding on Vaccinium uliginosum L. along an ecological gradient in central European pe…
2011
Parasitoids of leaf-spinning Lepidoptera associated with two isolated central European peat bogs were investigated. Five families of parasitoid Hymenoptera (Braconidae, lchneumonidae, Eulophidae, Pteromalidae and Encyrtidae) were recorded. Three categories were recognised: (1) primary parasitoids, (2) facultative hyperparasitoids and (3) obligatory hyperparasitoids. Ten species of Braconidae, five species and seven marked morphospecies among lchneumonidae, and three species of Chalcidoidea were identified. Despite of some niche-specific (but less host-specific) parasitoids, all these hymenopterans are likely to be generalists and none of them were confirmed to be habitat and/or host special…
