Socio-Demographic Variables, Fear of COVID-19, Anxiety, and Depression: Prevalence, Relationships and Explanatory Model in the General Population of …
2021
The COVID-19 pandemic has gravely impacted Latin America. A model was tested that evaluated the contribution of socio-demographic factors and fear of COVID-19 on anxiety and depression in samples of residents in seven Latin American countries (Argentina, Ecuador, Mexico, Paraguay, Uruguay, Colombia, and El Salvador). A total of 4,881 individuals, selected by convenience sampling, participated in the study. Moderate and severe levels of depressive symptoms and anxiety were identified, as well as a moderate average level of fear of COVID-19. In addition, it was observed that about a quarter of the participants presented symptoms of generalized anxiety disorder and a major depressive episode. …
Mast cells partly contribute to allergic enteritis development: Findings in two different mast cell-deficient mice
2021
Allergic enteritis (AE) is a gastrointestinal form of food allergy. The presence of mast cells and granulocytes has been detected in the inflamed tissues in AE. In this study, we aimed to elucidate the role of mast cells in AE development using two mast cell-deficient mouse strains: KIT(W-sh/W-sh) bearing the W-sash (W(sh)) inversion mutation and Cpa3Cre/+, which lack mast cells due to Cre-mediated mast cell eradication, were used in an AE experimental model. The development of clinical symptoms (e.g. drop in body temperature and weight loss) were abolished in both strains, whereas inflammatory levels of AE (e.g. villous atrophy, edema, and granulocyte accumulation) were reduced mainly in K…
Heterophyid trematodes (Digenea) from penguins: A new species of Ascocotyle Looss, 1899, first description of metacercaria of Ascocotyle (A.) patagon…
2019
Two species of heterophyid trematodes were found in the Magellanic penguin, Spheniscus magellanicus (Forster), from Patagonia, Argentina. Ascocotyle (Ascocotyle) patagoniensis Hernández-Orts et al. (2012) is re-described based on new, properly fixed specimens (original material from South American sea lion, Otaria flavescens Shaw, was from frozen hosts). Metacercariae of this species are reported and described for the first time from the heart of the silversides, Odontesthes argentinensis (Valenciennes) and O. smitti (Lahille), from Patagonia. Ascocotyle (Phagicola) cameliae n. sp. is described from the intestine of S. magellanicus. The new species is placed into the subgenus Phagicola Faus…
Strategic use of pictorial representations in a science text with a biographical seductive detail in low prior knowledge readers
2015
La Teoría Cognitiva de Aprendizaje Multimedia (Mayer, 2001, 2005) sostiene que el procesamiento conjunto de información lingüística y pictórica resulta en una representación mental integrada del mensaje, y que la adición de representaciones pictóricas puede tanto beneficiar como perjudicar el desempeño asociado a la lectura, dependiendo de la función que cumplan dichos agregados. Este estudio examinó experimentalmente el efecto de asociar representaciones pictóricas con un texto expositivo en castellano (una población sub-representada) que incluyó un dato biográfico tangencial pero interesante (detalle seductor). Ciento cuarenta y siete participantes con bajo conocimiento previo leyeron el …
Organizational Media Affordances: Operationalization and Associations with Media Use
2017
The concept of affordances has been increasingly applied to the study of information and communication technologies (ICTs) in organizational contexts. However, almost no research operationalizes affordances, limiting comparisons and programmatic research. This article briefly reviews conceptualizations and possibilities of affordances in general and for media, then introduces the concept of organizational media affordances as organizational resources. Analysis of survey data from a large Nordic media organization identified six reliable and valid organizational media affordances: pervasiveness, editability, self-presentation, searchability, visibility, and awareness. Eight media scales base…
Epistemic Search Sequences in Peer Interaction in a Content-based Language Classroom
2013
Epistemics in interaction refers to how participants display, manage, and orient to their own and others’ states of knowledge. This article applies recent conversation analytical work on epistemics to classrooms where language and content instruction are combined. It focuses on Epistemic Search Sequences (ESSs) through which students in peer interaction collectively resolve emerging knowledge gaps while working on pedagogic tasks. ESSs are initiated when a speaker displays an ‘unknowing’ epistemic stance by making an information request about some aspect of language or the content being worked on. We examine three different types of ESS: those in which a ‘knowing’ response is accepted by th…
Languaging in Ultima Thule: Multilingualism in the Life of a Sami Boy
2008
Abstract In this paper we investigate multilingualism as a phenomenon which pervades different social and cultural levels but is manifested in the everyday life of multilingual individuals. As an illustration, we examine multilingualism from the perspective of a young Sami boy, Ante, and explore how different languages function as a complex – but at times problematic – set of resources for him. To capture the complexity and fluidity in the relationships between various languages in his life, we base our theorising on such concepts as ‘linguistic resources’, ‘heteroglossia’ and ‘languaging’. With the help of multimodal data we examine how the linguistic resources present in Ante's daily life…
Openings in technology-mediated business meetings
2015
The prerequisites for opening a meeting, or beginning any kind of interaction for that matter, are participants’ presence and shared orientation towards the situation at hand. This paper analyses how the initial moments of technology-mediated business meetings involving distributed work groups are organized sequentially and multimodally. Drawing on video-recorded meetings in an international company, it documents the multimodal practices used in the process of establishing co-orientation to the shared meeting space and achieving entry into the meeting. The analysis shows that the stepwise unfolding of the opening phase requires the coordination of verbal and bodily conducts as well as the a…
Conflict management in massive polylogues: A case study from YouTube
2014
Abstract The aim of this paper is to examine how conflict begins, unfolds and ends in a massive, new media polylogue, specifically, a YouTube polylogue. Extant research has looked into how conflict begins, unfolds and/or ends. However, to our knowledge, the models and taxonomies developed so far have not been applied to the analysis of the mediated conflict of massive polylogues. Drawing on the difference between methods of analysis that are natively digital versus those that have been digitized, i.e., they were developed for off-line research and then migrated on-line, one of the goals of this paper is to test whether non-natively digital, extant models and taxonomies, if digitized, would …
