The aim of this study was to analyze whether children with and without difficulties in handwriting, spelling, or both differed in alphabet writing when using a keyboard. The total sample consisted of 1,333 children from Grades 1 through 3. Scores on the spelling and handwriting factors from the Early Grade Writing Assessment (Jiménez, in press) were used to assign the participants to one of four groups with different ability patterns: poor handwriters, poor spellers, a mixed group, and typically achieving students. Groups were equalized by a matching strategy, resulting in a final sample of 352 children. A MANOVA was executed to analyze effects of group and grade on orthographic motor integration (fluency of alphabet writing) and the number of omissions when writing the alphabet (accuracy of alphabet writing) by keyboard writing mode. The results indicated that poor handwriters did not differ from typically achieving children in both variables, whereas the poor spellers did perform below the typical achievers and the poor handwriters. The difficulties of poor handwriters seem to be alleviated by the use of the keyboard; however, children with spelling difficulties might need extra instruction to become fluent keyboard writers.
The main purpose of this study was to validate the curriculum-based measure Indicadores de Progreso de Aprendizaje en Matemáticas (IPAM [Indicators of Basic Early Math Skills]) in a local, Spanish-speaking context. This tool has been designed to identify first-grade students at risk for mathematics learning disabilities. The IPAM includes five measures (i.e., quantity discrimination, multi-digit computation, missing number, single-digit computation, and place value), which were analyzed as single measures and as part of a composite measure. In this study, 176 first graders were administered the curriculum-based measurement IPAM at the beginning, middle, and end of the school year. The results showed that the composite measure of the IPAM was the best indicator of risk status. Reliability and concurrent and predictive validity results were adequate. Furthermore, receiver operating curve analysis and hierarchical linear model supported the capacity of the IPAM to correctly identify students’ risk status and growth rate during first grade.
Purpose The integral approach to risk is currently an important background for the local development processes within the sustaintability framework. Given the greater frequency and intensity of extreme climatic events in the period 2005-2015, whose inventory shows a total of 78 extreme climate events in the four thermal stations, the purpose of this paper is to analyze risk situations and their corresponding management in the tourist destinations (TD) of the Atlantic coast of Buenos Aires, Argentina. Design/methodology/approach Risk management in TDs has not been addressed in depth in the study area. Because of that, this study is exploratory and descriptive, and it was conducted by quantitative and qualitative methods. The occurrence of extreme weather events was the trigger of this study. Thereafter, the existence of risk situations was analyzed from the combination of natural hazards and material and human damage. The actions taken by the public sector were identified to make a diagnosis of the current management of coastal destinations in the province of Buenos Aires. Findings The result of this study shows that TDs do not apply integral models of risk management, as only 16% of the total registered events were attended by public management from reactive measures to the event. It is believed possible to replicate this study in other TDs, regardless of its main tourism modality, as the analysis carried out in the coastal destinations of Buenos Aires shows that it is necessary to plan and manage risk to avoid and/or mitigate material, social and economic damages of the resident and tourist population. Practical implications The main implication of the study, in practical terms, is associated with the incorporation of specific equipment for the detection of storms and other meteorological phenomena. In addition, it should start, from the management, with a process of awareness of the resident and tourist population about the risk and its consequences. Social implications Knowing the existence of natural hazards is a strategic resource for public management. From the identification of the hazards, exposure and vulnerability of the population, it is possible to begin to take measures to mitigate the risk and conduct awareness campaigns about the risk situations that may arise from the occurrence of meteorological phenomena. in beach areas. In this sense, the development of a culture of risk is very important. Originality/value The relationship between the occurrence of extreme weather events and tourism has not been addressed in depth in Argentina. Therefore, this work provides an interdisciplinary vision (from tourism and physical geography) about the hazards that extreme phenomena represent in TDs, the situations of risk that they detaches there and the weakness of public management in coastal destinations of Buenos Aires. This case study shows that the absence of planning and risk management has serious implications for the continuity of the development processes of the destinations.
RESUMENEl estado ecológico de un río es aquella medida de calidad en la estructura y funcionamiento del ecosistema acuático. Los procesos geomorfológicos determinan una gran variedad de hábitats, favoreciendo la biodiversidad y productividad de los ecosistemas acuáticos y ribereños. Los indicadores hidrogeomorfológicos son claves para determinar el estado ecológico de los ríos. La dinámica hidrológica garantiza la biodiversidad, la calidad ambiental y la protección de todos los elementos del sistema y sus relaciones. El objetivo de este trabajo es conocer el estado ecológico de un tramo en la cuenca baja del arroyo San Bernardo, para lo cual se utilizó el Índice Hidrogeomorfológico
La morfometría fluvial ayuda a la interpretación del comportamiento morfodinámico e hidrológico en cuencas. La determinación de la escala de trabajo es importante ya que un cambio en la misma genera una variación en los resultados y modifi ca la aplicabilidad de los índices. Pero esta variación ¿se da en todos los índices? el objetivo de este trabajo es estudiar la morfometría fl uvial y comparar índices morfométricos a diferentes escalas espaciales en la cuenca del arroyo San Bernardo. La misma se ubica en el centro-sur del Sistema de Ventania, provincia de Buenos Aires (Argentina). Tiene una superfi cie de 82 km 2 , no posee aforo y en ella se generan crecidas torrenciales ante la ocurrencia de eventos de precipitación Informações sobre o Artigo Recebido (
