    This paper reports experiences of the Australian Centre for International Agricultural Research (ACIAR) Smallholder Forestry Project in the establishment of a working relationships with a people's organisation in Leyte Province, the Philippines. Strategies adopted in building a partnership with the organisation through the establishment of a community nursery, conduct of field trial research and the emerging practical impacts on smallholders are specifically discussed. Information presented in this paper is the outcome of documented field experiences during the research as well as informal discussions with members of the people's organisation. This project illustrates that within-community research can be an effective extension tool if local people are given the chance to participate in all stages of planning and implementation. Mere participation in research activities, however, is not enough. Ongoing interaction between the researchers and the local people is crucial in paving the way to partnership-building. The developmental partnership that was established has created practical impacts which may lead to more widespread adoption and promotion of farm and community forestry in Leyte Province

    Status of the Resource Room Model in Local Education Agencies: A Descriptive Study

    Although resource room programs are widely used, only limited information is available on implementation of this model. The purpose of the present investigation was to survey a nationwide sample of local education agencies (LEAs) to determine the status of this model at the local level and to identify the characteristics of resource programs as they are currently implemented. A questionnaire was sent to a 5% stratified random sample of LEAs with a 53.4% response rate. Results indicated that most local education agencies use resource room programs, and have done so for at least three years. Most programs are multicategorical. The majority of respondents indicated that they believed the programs were effective, and that they would continue to be used. A major conclusion from this study relates to the need for descriptions of model resource room programs and practices.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

    Utilisation de traceurs radioactifs pour l'évaluation du recrutement des leucocytes et des échanges vasculaires au niveau d'organes in vivoin~vivo. Description d'une méthode et discussion des problèmes d'interprétation sur quelques exemples

    An experimental method using simultaneously different γ\gamma emiter tracers was developed to evaluate inflammation in vivo. Experiments were performed on the anaesthetized guinea-pig to test pulmonary effects of inflammatory agents. Red blood cells, albumin and inflammatory cells (platelets or leucocytes) radiolabelled with 99m technetium, 131 iodine and 111 indium respectively were injected i.v. Their radioactivities were measured on a pulmonary region by external detection and on blood samples in a well type counter. From these measurements variations of the lung contents in red blood cells, extravascular albumin and non circulating leucocytes during inflammatory stimulation were evaluated. These parameters axe indexes of blood perfusion, vascular exchanges and leucocyte sequestration respectively. Fiability of the method and meaning of the parameters evaluated are discussed.Une méthode expérimentale utilisant simultanément différents traceurs γ\gamma a été développée pour évaluer l'inflammation in vivo. Des expériences ont été réalisées chez le cobaye anesthésié pour tester l'effet pulmonaire d'agents inflammatoires. Des globules rouges, de l'albumine et des cellules inflammatoires (plaquettes ou leucocytes) radiomarqués respectivement au technetium 99m, à l'iode 131 et à l'indium 111 sont injectés i.v. Leurs radioactivités sont mesurées sur une région pulmonaire par détection externe et sur des échantillons sanguins au compteur puit. À partir de ces mesures sont évaluées les variations des contenus pulmonaires en globules rouges, en albumine extravasculaire et en leucocytes non circulants lors d'une stimulation inflammatoire. Ces paramètres sont corrélés aux modifications de la perfusion, des échanges vasculaires et de la séquestration leucocytaire. La fiabilité de la méthode et la signification des paramètres évalués sont discutées
