    This systematic literature review investigated school counselling needs in East and Southeast Asia based on 109 studies from 14 countries published since 2011. School counselling needs were categorised using an international taxonomy (Morshed & Carey, Citation2020, Development of a taxonomy of policy levers to promote high quality school-based counseling. Journal of School-Based Counseling Policy and Evaluation, 2(2), 95–101). We found similarities and differences between the countries and nine main needs characterising the region. These include the need for (1) up-to-date training, (2) country specificmodels of school counselling practices stating school counsellors’ roles and responsibilities, and (3) overcoming societal-level barriers such as stigma towards mental health. We recommend context-sensitive steps to policymakers seeking to improve school counselling services

    During the last decade there has been a profound revolution in the information technology by means of the Internet, and obviously accounting has been directly affected by this change. Although the main objective of this paper is to study the use of the Internet by Spanish companies to disclose financial information, we also discuss about the reasons of companies to use the new technologies to communicate with interested parties and its consequences. The empirical research is based on companies listed on the Madrid stock exchange , we analyse not only the information provided, but also the factors that explain the different attitudes of companies towards this vehicle for investors relationships. The results show that size is the main factor that explains not only the quantity but also the quality of financial [email protected]

    The feasibility of implementing autism intervention methods in formal education settings welcoming refugee and asylum-seeking children: A systematic review of the literature

    Get PDF
    Given the significant amount of time that refugee and asylum-seeking children (RASC) spend in schools, these institutions play an important role in their lives and represent an ideal environment in which to help them to adapt to their host society. The present study aimed to draw attention to the possibility of transferring intervention methods designed for children with ASD to formal education settings welcoming newly arrived RASC to support their adaptation to their new school environment. For this purpose, a systematic review was undertaken to assess the feasibility of implementing three specific ASD intervention methods (i.e., TEACCH, PECS, and PMI) in schools welcoming RASC. While the review did not reveal previous attempts to implement and evaluate ASD intervention methods with newcomer RASC, 21 records were uncovered providing preliminary evidence in support of this idea. Hypothesized strengths and limitations, as well as considerations about implementation, are discussed

    El paso por el colegio secundario brinda herramientas para que podamos tener una revisión de nuestra historia, acercándonos al objetivo principal: conocer y reconocernos. Dos materias de gran importancia para cumplirlo son Historia y Literatura. Un anclaje entre ambas es esencial. Este artículo está orientado a la visión sobre la llegada de los españoles a América, lo que se debe enseñar según el diseño curricular y cómo la literatura argentina, en particular La saga de los confines, de Liliana Bodoc, puede ayudar a verlo desde otra perspectiva.Centro de Investigación en Lectura y Escritur

    Pisistrate au Lycée ou le temps de Cronos retrouvé

    Get PDF
    D’après Aristote, Constitution des Athéniens, XVI, 7, les Athéniens auraient vécu, sous Pisistrate, comme au temps de Cronos. Le choix d’Aristote d’associer le tyran athénien à l’âge d’or s’explique en étant replacé dans le contexte intellectuel et politique de production de la Constitution des Athéniens. Si la formule « la tyrannie de Pisistrate était la vie au temps de Cronos » prolonge la légende dorée du tyran née sous la plume d’Hérodote et de Thucydide, elle fait aussi écho aux conceptions historiographiques du IVe siècle qui ont tendance, avec les Xénophon, Isocrate, Théopompe et les Atthidographes, à se focaliser sur des individus exceptionnels et à envisager le passé de la cité athénienne sous un angle nostalgique et partisan. Le portrait de Pisistrate dans la Constitution des Athéniens porte également les marques des méthodes d’investigation du Lycée, puise ses qualités dans le panthéon des vertus aristotéliciennes et entend sans doute aussi participer au débat sur le bon dirigeant ouvert au IVe siècle par Xénophon, Platon et Isocrate. Il semble enfin envisageable de comprendre la survalorisation légendaire de Pisistrate dans la Constitution des Athéniens par la volonté d’Aristote d’utiliser le portrait du tyran athénien comme un miroir princier destiné à guider les actions d’Alexandre ou bien à convaincre les Athéniens des bénéfices à tirer de leur mise sous tutelle macédonienne.According to Aristotle in The Athenian Constitution, XVI, 7, the Athenians would have lived under Pisistratus as in Kronos days. Aristotle’s choice to associate the Athenian tyrant with the Golden Age can be explained by the intellectual and political context in which The Athenian Constitution had been written. If the phrase “Pisistratus’ tyranny was the life under Kronos” extends the tyrant’s golden legend – which was born thanks to the writings of Herodotus and Thucydides, it also echos the historiographical conceptions of the IVth century. Indeed, Xenophon, Isocrates, Theopompus, the Atthidographs, among others, tend to focus on very special individuals and to view the past of Athens with nostalgia and apartisan viewpoint. Pisistratus’portrait in the The Athenian Constitution is also characteristic of the methods of investigation used by the Lyceum, it draws its qualities from the pantheon of Aristotelian virtues: it also certainly aims at taking part in the debate on the good leader which began in the IVth century with Xenophon, Plato and Isocrates. Finally, it seems possible to understand the legendary overvaluation of Pisistratus in The Athenian Constitution through Aristotle’s will to use the Athenian tyrant’s portrait as a Mirror for Princes to guide Alexander’s actions. It might also be a way to convince the Athenians that they could benefit from their submission to the Macedonian authority

    Trajectories of positive and negative affect and state hope and their relationship with mental health among male adolescents in a juvenile correctional institution in China

    Positive affect and hope contribute to individuals’ psychological adjustment and positive youth development. The purpose of the study was to examine growth in positive and negative affect as well as state hope in Chinese adolescents in a juvenile correctional institution. We also investigated whether distinct trajectories of affect and hope predicted mental health and externalizing, internalizing, and prosocial behavior. The study included 198 male adolescents in a Chinese juvenile correctional institution and comprised nine measurement points (T1-T9) which were one week apart, respectively. Positive and negative affect and state hope were assessed from T1 to T8, and mental health and internalizing, externalizing, and prosocial behavior were measured at T9. Analyses of latent growth curve and latent class growth models were estimated. It was found that positive and negative affect, as well as state hope, decreased over time. Youth in classes characterized by higher state hope and lower negative affect reported better mental health than youth in classes characterized by lower levels of these constructs. Because of the beneficial effects of lower negative affect and higher state hope on mental health and internalizing, externalizing, and prosocial behavior, interventions strengthening hope and reducing negative affect may promote positive youth development in juvenile correctional institutions

    In vitro antagonistic activity of Trichoderma harzianum against Fusarium sudanense causing seedling Blight and seed rot on wheat

    Get PDF
    [EN] Fusarium sudanense is a novel fungus recently isolated from asymptomatic samples of wheat grains in Argentina. The fungus caused symptoms of seedling blight and seed rot on wheat after artificial inoculations. It is known that the production of mycotoxins by pathogens belonging to the Fusarium genus is harmful to human and animal health. Moreover, the warm and humid conditions that are favorable for growth and mycotoxin production of these species put the Argentinian wheat production area at a high risk of mycotoxin contamination with this novel pathogen. The aim of this work was to evaluate the antagonistic effect of Trichoderma harzianum against F. sudanense under in vitro tests at different environmental conditions. Fungi were screened in dual culture at different water activities (alpha(w)) (0.995, 0.98, 0.95, and 0.90) and temperatures (25 and 15 degrees C). The growth rate of the fungi, interaction types, and dominance index were evaluated. Also, the interaction between T. harzianum and F. sudanense was examined by light and cryo-scanning microscopy. T. harzianum suppressed the growth of F. sudanense at 0.995, 0.98, and 0.95 alpha(w) at 25 degrees C and 0.995 and 0.98 alpha(w) at 15 degrees C. Macroscopic study revealed different interaction types between F. sudanense and T. harzianum on dual culture. Dominance on contact where the colonies of T. harzianum overgrew the pathogen was the most common interaction type determined. The competitive capacity of T. harzianum was diminished by decreasing the temperature and alpha(w). At 0.95 alpha(w) and 15 degrees C, both fungi grew slowly, and interaction type "A" was assigned. Microscopic analysis from the interaction zone of dual cultures revealed an attachment of T. harzianum to the F. sudanense hyphae, penetration with or without formation of appressorium-like structures, coiling, plasmolysis, and a veil formation. According to our results, T. harzianum demonstrated capability to antagonize F. sudanense and could be a promising biocontrol agent.This work was supported by the Escuela Tecnica Superior de Ingenieria Agronomica y del Medio Natural (ETSIANM), UPV, Spain, and by Facultad de Ciencias Agrarias y Forestales of the Universidad Nacional de La Plata (grant no. 11A 296), Argentina.Larran, S.; Santamarina Siurana, MP.; Rosello Caselles, J.; Simón, MR.; Perelló, A.

    D376E, A205V and A122S substitutions recently found in A. palmeri confer cross-resistance to ALS-inhibiting herbicides

    Get PDF
    Background: Amaranthus palmeri S. Watson is a serious problem in soybean crops from Argentina. This weed has evolved high level of resistance to (ALS)-inhibiting herbicides mainly due to a target-site mechanism by an altered ALS enzyme. In an A. palmeri population from Totoras with cross-resistance to (ALS)-inhibiting herbicides, six allelic versions of the ALS enzyme were identified.Objective: The aim of this study was to evaluate plants from that resistant population carrying the ALS substitutions A122S, D376E or A205V, which had not been characterized before for this species.Methods: Subpopulations with each substitution were produced by a vegetative cloning procedure or by cross-pollination and dose-response assays and herbicide single-dose tests were performed to evaluate in vivo resistance levels to (ALS)-inhibiting herbicides.Results: Dose-response experiments showed that all the resistant subpopulations survived at the highest doses tested (32 X) for imidazolinones, triazolopyrimidines and sulfonylureas, while the susceptible population was completely controlled at considerably lower doses. Furthermore, an analysis of the novel A122S substitution showed that it provides cross-resistance to five classes of (ALS)-inhibiting herbicides, excluding the entire ALS herbicide group as an effective control tool in weed populations carrying this substitution.Conclusions: The results indicated that D376E, A205V and A122S substitutions found for the first time in A. palmeri confer cross-resistance to the most used chemical families from herbicide group 2. Interestingly, it was confirmed that the A205V substitution conferred resistance to herbicides in the triazolopyrimidines family. Data generated should be considered in management strategies for delaying the spread of resistance.Fil: Palmieri, Valeria Esther. Consejo Nacional de Investigaciones Científicas y Técnicas.
