Comparative study on the learning styles of argentine university students from different disciplines

La alfabetización académica exige el dominio progresivo de las formas textuales y discursivas propias de cada disciplina. El objetivo de este estudio es indagar los estilos de aprendizaje de estudiantes universitarios, estableciendo comparaciones según el tipo de episteme (Ciencias Humanas-Ciencias Exactas). Se realizó un estudio descriptivo-correlacional de corte transversal. Se aplicó el Inventario de Estilos de Aprendizaje de Felder y Soloman (1998) a 62 estudiantes de Ingeniería y 71 de Psicología de primer año de una universidad pública argentina. Los estudiantes inician su formación académica con distintos estilos de aprendizaje. Las discrepancias encontradas se acentuaron según el tipo de disciplina, y se obtuvieron diferencias estadísticamente significativas en los estilos de percepción (sensorial-intuitivo), representación (visual-verbal)y comprensión (secuencial-global). Los estudiantes de Ingeniería se definieron como sensoriales y visuales; en cambio, las orientaciones en Psicología son intuitivas, verbales y secuenciales. Implicancias educativas son discutidas.Academic literacy requires the progressive mastery of textual and discursive forms of each discipline. The aim of this study is to analyze the learning styles of college students, comparing them by type of episteme (Human Sciences- Sciences). The research was a descriptive-correlational study with a transversal design. We applied the Index of Learning Styles of Felder & Silverman (1998) to 62 engineering students and 71 psychology students of first-year of a public university in Argentina. The main results show that students begin higher education with different learning styles. The discrepancies found were accentuated by the type of discipline; obtaining statistically significant differences in the styles of perception (sensory-intuitive), representation (visual-verbal) and comprehension (sequential-global).The engineering students were defined as sensory and visual. Instead, the guidelines in Psychology are intuitive, verbal, and sequential. Educational implications are discussed.Fil: Ventura, Ana Clara.

Trends in the Pattern and Variability of Rainfall in the Loch Lomond Basin, Scotland

The nature of present climatic change is causing general concern, mainly due to the assumption that this change is due to anthropogenic forcing. This study aims to examine annual and seasonal changes in rainfall regime over West Central Scotland and to evaluate the consequent wider effects on the area. For this purpose 14 series of monthly rainfall data were analysed from the records from 28 sites within and outside the Loch Lomond basin in West Central Scotland. Each series includes all of the records available, the shortest has 18 years and the longest has 121 years of record, with some series composed of a grouping of several stations. Gaps in the records are filled in the series by estimation and the homogeneity of the final data set is checked. The nature of temporal rainfall trends in pattern and variability over the Loch Lomond area is examined using different techniques of time-series analysis for annual (Oct.-Sep.), Winter half-year (Oct.-Mar.) and Summer half-year (Apr.-Sep.) rainfall amounts. The nature of spatial trends in the pattern and variability of rainfall is examined by isohyetal maps for standard periods of average annual rainfall. The different kinds of data presentation are examined for evidence of changes in the patterns of annual and seasonal increcises and decreases in dry and wet years, and in terms of interannual rainfall variability. The overall trends and changes in spatial variability are also investigated. The study confirms a marked trend towards increasing wetness over Central West Scotland during the last two decades as noted in earlier studies of wider coverage. From 1968/69 to 1991/92 the increase over the Loch Lomond basin was 76.6%. Furthermore it is demonstrated that this trend to increased rainfall has had no similar occurrence in the last 121 years, although important fluctuations have occurred. Spatially, the Northwest part of the Loch Lomond basin is wetter and the records indicate a greater rainfall increase in the recent two decades compared to the Southeast. Possible causes of increasing rainfall related to changes in the general circulation and local conditions and the wider implications for the hydrological system and land use are discussed. The trends towards an increase in rainfall are consistent with theoretical experiments related to global warming linked with an enhanced 'greenhouse effect', but it is possible that they may reflect a return to conditions of earlier periods. The results of this study are particularly significant as they serve as a detailed indicator of climate change in West Central Scotland and constitute the basis for future planning of basin management in the Loch Lomond area

The Effect of Nanomaterials on DNA Methylation: A Review

ReviewThis article belongs to the Special Issue Interaction of Nanomaterials with Biological Systems: In Vitro and In Vivo Studies.DNA methylation is an epigenetic mechanism that involves the addition of a methyl group to a cytosine residue in CpG dinucleotides, which are particularly abundant in gene promoter regions. Several studies have highlighted the role that modifications of DNA methylation may have on the adverse health effects caused by exposure to environmental toxicants. One group of xenobiotics that is increasingly present in our daily lives are nanomaterials, whose unique physicochemical properties make them interesting for a large number of industrial and biomedical applications. Their widespread use has raised concerns about human exposure, and several toxicological studies have been performed, although the studies focusing on nanomaterials’ effect on DNA methylation are still limited. The aim of this review is to investigate the possible impact of nanomaterials on DNA methylation. From the 70 studies found eligible for data analysis, the majority were in vitro, with about half using cell models related to the lungs. Among the in vivo studies, several animal models were used, but most were mice models. Only two studies were performed on human exposed populations. Global DNA methylation analyses was the most frequently applied approach. Although no trend towards hypo- or hyper-methylation could be observed, the importance of this epigenetic mechanism in the molecular response to nanomaterials is evident. Furthermore, methylation analysis of target genes and, particularly, the application of comprehensive DNA methylation analysis techniques, such as genome-wide sequencing, allowed identifying differentially methylated genes after nanomaterial exposure and affected molecular pathways, contributing to the understanding of their possible adverse health effects.This research received funding from the Portuguese Foundation for Science and Technology (FCT/MCTES) under the project ToxApp4NanoCELFI (PTDC/SAUPUB/32587/2017) and projects UIDB/00009/2020 and UIDP/00009/2020 (ToxOmics).info:eu-repo/semantics/publishedVersio

QUALITY, SAFETY AND CONSUMER BEHAVIOUR TOWARDS ORGANIC FOOD IN GERMANY AND PORTUGAL

The goal of this paper is to compare Portuguese and German consumer behaviour towards Organic Food Products (OFP). For this purpose, an extensive literature review on quality and food safety of organic food products was carried out and a consumer survey was implemented, with data collected by means of personal interviews in the capital cities of the two countries. The data was analysed using descriptive statistics and a comparison of Portuguese and German consumers was made with the help of chi-square tests and ANOVA. The results show positive consumer attitudes towards OFP. However, its consumption is much lower than could be expected from these attitudes. Intentions to buy OFP are quite high, suggesting that these products might obtain a substantial market share in the future. This is an encouraging sign for prospective producers of OFP, who might compensate the likely increase in unitary production costs with an increase in total production. The study presented in this paper is the result of a research project supported by the programme "CRUP - Acções Integradas Luso Alemãs 2004" in Portugal and by the programme "Des Projektbezogenen Personenaustauschs (PPP) 2004 mit Portugal" in Germany.Organic food products, consumer behaviour, Germany, Portugal.

Cytogenetic analyses in a group of patients with myelodysplastic syndromes

Myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal disorders of haematopoietic stem cell diseases characterised by dysplasia and ineffective haematopoiesis in one or more of the major myeloid cell lines. This disease occurs predominantly in older adults where the median age at diagnosis is approximately 70 years. The aim of this study was to evaluate the data from cytogenetic analyses in 425 patients with myelodysplastic syndromes. This population was constituted by 212 females and 213 males; the median age at diagnosis is 66 years. Numerical and structural chromosomal abnormalities were documented for each patient and subdivided according to the number of additional abnormalities. From the 425 cytogenetic analyses, 97 (22.8%) were abnormal. The results for the abnormal population were as follows: 73.2% had only one anomaly, 9.3%had two anomalies, and 17.5%had a complex karyotype. In the abnormal population, the most frequent isolated anomaly observed was the trisomy 8 (17.5%), followed by the deletion of chromosome 5 (13.4%), the loss of chromosome Y (11.3%) and the deletion of chromosome 20 (8.2%). When associating these anomalies with complex karyotypes, the most frequent anomaly observed was the deletion of chromosome 5 (24.7%). Overall, these results are different fromthose in the literature; however, the deletion of chromosome 5 is still the most recurrent anomaly in this syndrome.We can also conclude that the loss of chromosomeYis not always associated with age, but is one of the anomalies that characterize this group of pathologies. All these anomalies were found by cytogenetic analysis, a low-cost technique that allows clinicians to use this important prognostic tool to evaluate and make a more accurate clinical decision for patients with MDS

Teaching and learning styles at higher education: social and cognitive dimension of stylistic approach

El objetivo de este trabajo es describir los estilos de aprendizaje de estudiantes y los de enseñanza de docentes, así como las configuraciones de asociación entre los mismos (grados de armonización/discrepancia y modos de relación) según el área de conocimiento (ciencias sociales-ciencias exactas) y el ciclo de la formación académica (introductorio-básico-superior). La muestra, seleccionada intencionalmente, estuvo compuesta por seis grupos áulicos compuestos por estudiantes y docentes: tres de Psicología y tres de Ingeniería. Se encontraron preferencias de enseñanza y aprendizaje diferenciadas según la carrera: preferencias intuitivas-reflexivas-verbales- globales en Psicología, y, preferencias sensoriales-activas-visuales- secuenciales en Ingeniería. Respecto a la configuración de asociaciones estilísticas, se encontró que los estudiantes más avanzados de cada carrera universitaria expresaron preferencias de aprendizaje tendientes hacia la armonización con las preferencias de enseñanza de sus docentes respecto a los estudiantes de los Ciclos inferiores, de modo que en un sentido amplio estos estudiantes reflejaron, a nivel del aprendizaje, las preferencias que se correspondían con las preferencias de sus docentes, a nivel de la enseñanza. En este sentido, es posible inferir que dicha armonización se produjo por cierto cambio en las preferencias de los estudiantes en vías hacia la alineación con los estilos dominantes de sus docentes.The aim of this paper is to describe the learning and learning styles and degrees of harmonization and modes of relationship by academic field and study year (first, third and fifth). The sample, selected intentionally, consisted of six groups composed by students and teachers: three of Psychology and three of Engineering. Learning and teaching styles were differentiated across academic field: preferences intuitivereflective-verbal-global in Psychology, and preferences visual-sensory-activesequential in Engineering. Regarding stylistic associations, learning styles tend to harmony with teaching styles, especially in upper level of academic training . In this sense, it is possible to infer that such harmonization was caused by some change in the preferences of the students on track toward alignment with the dominant styles of their teachers.Fil: Ventura, Ana Clara.

Dental decay in the change of deciduous teeth: the child’s self-perception

Background: Currently in Portugal, the percentage of children aged five to twelve who have already been to an oral health appointment is 57.6%. The prevalence of dental caries has declined over recent years, with the expectation that by 2020, 59% of Portuguese children will be caries-free. Objective: The present study aimed to understand how children from this age group experience the mental representation of dental decay and its implications on the self-perception inherent to the loss of deciduous teeth. Method: The sample consisted in 50 children of both genders, aged 5 - 12 years. A protocol was originally conceived where they were invited to draw two self-portraits - before and after the loss of deciduous teeth - and to answer open-ended questions with regards to such. The interpretation of the drawings and the open-ended questions were carried out through content analysis grids designed for such. Results: Regarding the written answers to the open-ended question “Why do you think teeth fall out?”, caries do not appear to be associated with the loss of deciduous teeth but rather “Bug” and “Bacteria”, identified as the most representative categories (27.9% and 18,9% respectively), which is in agreement with the symbolic representation depicted in drawings. Conclusions: The results obtained contribute to the (re)conceptualization of caries in this age group of children, which is also associated to the loss of deciduous teeth. The results also point to the need for developing educational tools for Oral health Education, in order to prevent caries in deciduous teeth and to foster good oral hygiene habits.info:eu-repo/semantics/publishedVersio
