Abstract Many parameters may be used to measure the deterioration of water quality. One very important parameter is total dissolved solids (TDS). An increase in TDS beyond acceptable levels can have a significant impact on municipal, industrial, and agricultural use of water. In this review an overview of the problem of high TDS levels is given. Factors related to TDS which are considered include: (a) laboratory determination, (b) natural and man-influenced sources, (c) adverse effects, and (d) treatment process removal techniques. A brief summary of the TDS problem associated with the Colorado River is also considered. 相似文献

RESUMENLa idea del Ministerio de Educación es que existen niños con alguna “deficiencia clínica” pero recuperables, y para estos niños se ha previsto la existencia del aula de transición dentro de la escuela para “niños normales” como vía de integración. Pero estas aulas han sido creadas sin ningún criterio lógico (en ellas encontramos niños con deficiencias psíquicas leves, con problemas de sociabilidad, con dificultades en el aprendizaje,…) y sin ninguna orientación determinada. En definitiva, se convierten en lugares de perpetua marginación. Para paliar la situación actual serían necesarias unas condiciones mínimas: dotar a la escuela de los medios necesarios para prevenir y tratar deficiencias; y la necesidad de que sean psicólogos los que ocupen las vacantes de esas aulas de educación especial, trabajando al mismo tiempo con el profesorado en las tareas del centro. 相似文献

ResumenDesde un Instituto de Bachillerato se propone una programación que contempla diversos aspectos relacionados con el Consumo y que tiende a estimular una actitud consciente y analítica desde la vida escolar. Se desarrolla en torno a las asignaturas del Seminario de Ciencias Naturales, aunque propicia frecuentes relaciones multidisciplinares. 相似文献

ResumenEl propósito de este estudio fue diseñar un modelo válido para la adquisición de unos adecuados hábitos de estudio, basado en una combinación de estrategias de autorregulación y técnicas de estudio. Se procedió mediante un diseño exploratorio de línea de base múltiple, con un único sujeto que incluía: a) fase de pretest, b) primera fase de intervención, en la que se introdujeron las estrategias de autorregulación, c) segunda fase de intervención o de introducción de las técnicas de estudio, y d) fase de postest. El resultado fue un cambio experimental y terapéuticamente significativo en los hábitos de estudio y en las conductas exponentes de: tiempo de estudio, desatención, y velocidad y comprensión lectoras, las calificaciones experimentaron un ascenso progresivo. Estos cambios se mantuvieron y consolidaron en el seguimiento, las estrategias de autorregulación se han mostrado útiles para aumentar la probabilidad de ocurrencia de la conducta deseada y disminuir la de la no deseada. 相似文献

Acquiring complex conceptual knowledge requires learners to self-regulate their learning by planning, monitoring, and adjusting the process but they find it difficult to do so. In one experiment, we examined whether learners need broad systems of support for self-regulation or whether they are also able to learn with more economical support configurations. Eighty-six undergraduate students with little prior domain knowledge learned plate tectonics from a multimedia presentation involving animation with concurrent narration and support in one of four forms: minimal support, two variants of intermediate support, or extensive support. After the presentation, participants solved retention and transfer tests. The results revealed that participants receiving the broadest system of support outperformed those in the other conditions, which did not differ from one another. This means that it is so difficult for learners to self-regulate learning that they need considerable support if they are to learn complex conceptual knowledge. 相似文献

Our country's increasing social diversity, the richness and complexity of cultures, diversity of self‐defined individual identities, and complexity of cross‐cultural interactions make effective diversity teaching a challenging but critical need. In addition, for services to be provided in culturally competent manner educators must prepare social work students to understand and address the causes, dynamics and consequences of oppression in the life experiences of diverse populations. This article will describe a graduate travel study social work course designed to provide a cultural immersion experience in Puerto Rico. Anecdotal evidence of the students' transformative learning experiences and commitment to social justice advocacy are offered. 相似文献

The current study analyzes the processes involved in obtaining technological innovations. Conclusive results are lacking in the literature, so this work defines and empirically tests a model of the relations between the firm's innovative capacity and the different ways of accumulating knowledge and the decision whether or not to codify it. Also, the model takes into account whether the innovations obtained are radical or incremental.The empirical study uses a sample of Spanish biotechnology firms, and the results show that accumulating knowledge using internal sources and not codifying it significantly improves the firm's capacity to develop radical innovations. The results also show that knowledge codification speeds up the development of incremental innovations. The relation between incremental innovations and the sources of knowledge is not so clear, although the results suggest the possible existence of a nonlinear relation between the two variables. 相似文献

ABSTRACT To assess the effects of plyometric jump training (PJT) in female soccer player’s vertical jump height, a review was conducted using the data sources PubMed, MEDLINE, Web Of Science and SCOPUS. Only peer-review articles were included. To qualify for inclusion in the meta-analysis, studies must have included (i) a PJT programme of at least 2 weeks, (ii) cohorts of healthy female soccer players with no restriction for age, (iii) a control group, (iv) a measure of countermovement jump (CMJ). The inverse variance random-effects model for meta-analyses was used. From 7,136 records initially identified through database searching, 8 were eligible for meta-analysis, comprising 9 training groups (n = 99) and 9 control groups (n = 94). The magnitude of the main effect was moderate (ES = 1.01 [95%CI = 0.36–1.66], Z = 3.04, p = 0.002). Sub-group analyses were performed (i.e., PJT frequency, duration and total number of sessions), revealing no significant subgroup differences (p = 0.34–0.96). Among the studies included in this review, none reported injury or other adverse effects. In conclusion, PJT is effective in female soccer players for the improvement of vertical jump height. In future, research must identify specific dose–response relationships following PJT, particularly in the long term. 相似文献
