323	Comunicação de riscos relacionada a agrotóxicos no Pólo floricultor de Nova Friburgo, RJ / Risk communication related to pesticides in the Hub florist Nova Friburgo, RJ Belo, Mariana Soares da Silva Peixoto January 2009 (has links) Made available in DSpace on 2011-05-04T12:36:21Z (GMT). No. of bitstreams: 0 Previous issue date: 2009 / O uso intensivo de agrotóxicos nas lavouras desacompanhado de políticas normativas e de controle resulta numa série de impactos sobre a saúde humana e sobre o meio ambiente. As intoxicações sofridas pelos trabalhadores rurais podem estar atreladas a vários fatores como, por exemplo, a dificuldade de compreensão das informações sobre os agrotóxicos. Uma solução seria uma assistência técnica mais eficaz e dissociada das casas comerciais, fato cada vez mais presente, acarretando o aumento no consumo desses produtos. Em alguns casos, o acesso às informações fica restrito somente à leitura de bulas e rótulos dos produtos utilizados, sendo a única fonte de comunicação de riscos existente. É um dado preocupante, já que é reconhecido o baixo nível de escolaridade dos agricultores. O presente estudo tem como objetivo analisar o processo de comunicação de riscos relacionado aos agrotóxicos no trabalho rural do Pólo Floricultor de Nova Friburgo/ RJ, através de um estudo de recepção de informações, por parte de agricultores, referente aos rótulos e bulas dos principais agrotóxicos utilizados por eles durante o seu processo de trabalho. Através de uma abordagem qualitativa, foram aplicados questionários semi-estruturados a 29 dos 30 produtores de flores locais, avaliando o seu processo de trabalho, seus anseios e o conhecimento acerca das questões que envolvem o uso dos agrotóxicos. A análise dos dados identificou uma série de situações relacionadas com o nível de informações e a sua interpretação pelos trabalhadores; o manejo indevido atribuído ao desconhecimento dos reais riscos que estão expostos é uma delas. Os resultados encontrados criam novas expectativas para a adoção de uma política eficaz de comunicação de riscos no campo, sobre tudo com a participação ativa de políticas normativas e que garantam o entendimento das instruções por pessoas comuns, conforme previsto na Legislação. O estudo subsidia uma estratégia mundial voltada para a harmonização global de informações dos produtos químicos, tendo como foco, os agrotóxicos. Uma comunicação de riscos mais segura, eficaz e ética pode ser caminho para garantir maior segurança aos trabalhadores. / The intensive use of pesticides for crop protection results in impacts on human and environmental health status, particularly when this use is not associated with normative policies and control actions. Major rural workers poisonings can be straight associated to a number of factors, including difficulties to comprehend the available information. One of many solutions should be a more effective and independent technical assistance, dissociated with commercial interests – a serious situation usually more seen and that can be pointed as one of the main determinants of pesticides use increase in the last few years. In some cases, information access is restricted to labels reading, constituting the only information resource available for a large group of rural workers. This situation is even more serious considering these professionals’ low formal-educational background. The present study aims to analyze pesticides risk communication process in a rural, flower-producer community of Nova Friburgo municipality, Rio de Janeiro State – Brazil, through an information-reception study focusing labels reading. Through a qualitative health research approach, semi-structured questionnaires were applied to 29 of the 30 local flower producers aiming to characterize local work processes, workers beliefs and perceptions, as well as to identify their ability to correctly understand pesticides labels information (visual and written). Results showed that this information is not correctly understood by workers, leading to some unsafe work practices such as inappropriate pesticides formulation and use and several exposures situations, as well as the non-adoption of protective gear. These data point the need of a more effective risk communication policy, particularly involving the community, that be effectively representative of what the National Legislation demands (all pesticides information present in labels should be correctly understood by any people, independent of their academic background). This study can be used as a subsidy for the GHS implementation in Brazil, particularly regarding pesticides information legislation.

324	Mutations affecting tomato (Solanum lycopersicum L. cv. Micro-Tom) response to salt stress and their physiological meaning / Mutações afetando a resposta ao estresse salino em tomateiro (Solanum lycopersicum L. cv. Micro-Tom) e seu significado fisiológico Ariadne Felicio Lopo de Sa 13 July 2016 (has links) Salinity is a challenge for crop productivity. Hence, plants exposed to saline environments reduce their vegetative and reproductive growth due to adverse effects of specific ions on metabolism and water relations. In order to cope with salinity, plants display physiological mechanisms based on three main aspects: i) source-sink relationships, ii) resource allocation and iii) alterations in endogenous hormone levels. The roles of developmental and hormonal mechanisms in salt response were investigated here. We employed mutants and transgenic tomato plants affecting different aspects of plant development and hormone response in the same genetic background (cultivar Micro-Tom). The following genotypes were used: Galapagos dwarf (Gdw), Lanata (Ln), lutescent (l), single flower truss (sft), sft heterozygous (sft/+), diageotropica (dgt), entire (e), Never ripe (Nr), epinastic (epi), procera (pro), notabilis (not), anti sense Chloroplastic carotenoid cleavage dioxygenase 7 (35S::asCCD7) and Salicylate hydroxylase (35S::nahG). Among the developmental genotypes studied, sft and l, involved in flower induction and senescence, respectively, were less affected when exposed to salt stress. Although l is considered deleterious due to its precocious senescence, it presented greater shoot biomass and leaf area during salinity. The heterozygous sft/+, whose high productivity was recently linked to an improved vegetative-to-reproductive balance, changed this balance and lowered its yield more than the control MT upon salt treatment. In the analysis of genotypes affecting hormonal status/signaling four kinds of salt responses among the genotypes were observed: i) High shoot growth in spite of high Na:K ratio presented by the strigolactone deficient and high branching CCD7 transgene; ii) High shoot growth and reduced accumulation of Na in tissues (probably due to dilution) presented by the auxin constitutive response e mutant; iii) The opposite response observed in \"ii\" presented by the low auxin sensitivity dgt mutant and iv) growth inhibition combined with reduced levels of Na and higher accumulation of K presented by the not mutant, which produces less ABA. Taken together, the results presented here points to novel developmental mechanisms, such as the promotion of moderate senescence and vegetative growth, and hormonal imbalances to be explored in the pursuing of crops resistant to salt stress. / A salinidade é um desafio para a produtividade agrícola, uma vez que plantas expostas à salinidade tem o crescimento vegetativo e reprodutivo reduzido devido aos efeitos adversos de íons específicos no metabolismo e nas relações hídricas. A fim de lidar com a salinidade, as plantas desempenham mecanismos fisiológicos baseados em três principais características: i) relações fonte-dreno; ii) alocação de reservas e iii) alterações nos níveis endógenos de hormônios. Nesse trabalho, investigamos a relação entre os processos de desenvolvimento e de regulação hormonal com a resposta à salinidade. Para tanto foram usados genótipos de tomateiro com alteração em diferentes vias de desenvolvimento e de produção ou sinalização de hormônios vegetais. Os seguintes genótipos foram usados: Galapagos dwarf (Gdw), Lanata (Ln), lutescent (l), single flower truss (sft), sft heterozygous (sft/+), diageotropica (dgt), entire (e), Never ripe (Nr), epinastic (epi), procera (pro), notabilis (not), anti sense Dioxigenase cloroplastídica de carotenoide 7 (35S::asCCD7) e Salicilato hidroxilase (35S::nahG). Entre os genótipos de desenvolvimento estudados, sft e l, relacionados à menor indução floral e senescência respectivamente, foram os menos afetados quando expostos à salinidade. O genótipo l acumulou maior biomassa e área foliar, apesar de ser considerado deletério devido à senescência precoce. As plantas heterozigotas, sft/+, cuja maior produtividade foi recentemente relacionada a um melhor balanço vegetativo/reprodutivo, alteraram esse balanço sob salinidade e reduziram sua produtividade mais que o controle MT sob estresse salino. Na análise dos genótipos com alteração hormonais foram observados quatro tipos de respostas à salinidade: i) elevado crescimento da parte aérea, apesar da razão Na:K ser alta no genótipo CCD7 cujo transgene induz deficiência de estrigolactona e excessiva ramificação; ii) elevado crescimento e acúmulo reduzido de Na nos tecidos (devido provavelmente a diluição) apresentada pelo mutante de resposta constitutiva a auxina e; iii) o oposto da resposta anterior foi apresentado pelo mutante pouco sensível à auxina , dgt; iv) inibição do crescimento combinado com nível reduzido de Na e alto acúmulo de K apresentada pelo mutante not que produz menos ácido abscísico. Considerados em conjunto, os resultados apresentaram temas para novos mecanismos de desenvolvimento, como a promoção moderada de senescência e do crescimento vegetativo além dos desbalanços hormonais, para serem explorados na busca de culturas resistentes ao estresse salino.

326	The effect of floral resources on the leafroller (Lepidoptera: Tortricidae) parasitoid Dolichogenidea tasmanica (Cameron)(Hymenoptera: Braconidae) in selected New Zealand vineyards Berndt, Lisa A. January 2002 (has links) In this study, buckwheat (Fagopyrum esculentum Moench) and alyssum (Lobularia maritima (L.)) flowers were used to examine the effect of floral resources on the efficacy of the leafroller parasitoid Dolichogenidea tasmanica (Cameron) in vineyards. This was done by assessing the influence of these flowers on parasitoid abundance and parasitism rate, and by investigating the consequences of this for leafroller abundance. In laboratory experiments, alyssum flowers were used to investigate the effect of floral food on the longevity, fecundity and sex ratio of D. tasmanica. Dolichogenidea tasmanica comprised more than 95 % of parasitoids reared from field collected leafrollers in this study. The abundance of D. tasmanica during the 1999-2000 growing season was very low compared with previous studies, possibly due to the very low abundance of its leafroller hosts during the experiment. The number of males of this species on yellow sticky traps was increased (although not significantly) when buckwheat flowers were planted in a Marlborough vineyard; however, the number of female D. tasmanica on traps was no greater with flowers than without. The abundance of another leafroller parasitoid, Glyptapanteles demeter (Wilkinson)(Hymenoptera: Braconidae), on traps was also not significantly affected by the presence of buckwheat flowers, although females of this species were caught in greater numbers in the control than in buckwheat plots. Naturally-occurring leafrollers were collected from three vineyard sites in Marlborough, and one in Canterbury during the 2000-2001 season to assess the effect of buckwheat and alyssum flowers on parasitism rate. Parasitism rate more than doubled in the presence of buckwheat at one of the Marlborough vineyards, but alyssum had no effect on parasitism rate in Canterbury. A leafroller release/recover method, used when naturally-occurring leafrollers were too scarce to collect, was unable to detect any effect of buckwheat or alyssum on parasitism rate. Mean parasitism rates of approximately 20 % were common in Marlborough, although rates ranged from 0 % to 45 % across the three vineyard sites in that region. In Canterbury in April, mean parasitism rates were approximately 40 % (Chapter 4). Rates were higher on upper canopy leaves (40-60 %) compared with lower canopy leaves and bunches (0-25 %). Leafroller abundance was apparently not affected by the presence of buckwheat in Marlborough, or alyssum in Canterbury. Buckwheat did, however, significantly reduce the amount of leafroller evidence (webbed leafroller feeding sites on leaves or in bunches) in Marlborough, suggesting that the presence of these flowers may reduce leafroller populations. Leafrollers infested less than 0.1 % of Cabernet Sauvignon leaves throughout the 1999-2000 growing season, but increased in abundance in bunches to infest a maximum of 0.5 % of bunches in late March in Marlborough. In Pinot Noir vines in the 2000-2001 season, leafroller abundance was also low, although sampling was not conducted late in the season when abundance reaches a peak. In Riesling vines in Canterbury, between 1.5 % and 2.5 % of bunches were infested with leafrollers in April. In the laboratory, alyssum flowers significantly increased the longevity and lifetime fecundity of D. tasmanica compared with a no-flower treatment. However, daily fecundity was not increased by the availability of food, suggesting that the greater lifetime fecundity was related to increases in longevity. Parasitoids were also able to obtain nutrients from whitefly honeydew, which resulted in similar longevity and daily fecundity to those when alyssum flowers were present. The availability of food had a significant effect on the offspring sex ratio of D. tasmanica. Parasitoids reared from naturally-occurring leafrollers produced an equal sex ratio, assumed to be the evolutionarily stable strategy (ESS) for this species. In the laboratory, this ESS was observed only when parasitoids had access to alyssum flowers. Without food, or with honeydew only, sex ratios were strongly male-biased. In the field, floral resources affected the sex ratio of D. tasmanica only when this species was reared from leafrollers released and recovered in Marlborough. In that experiment, buckwheat shifted the sex ratio in favour of female production from the equal sex ratio found in control plots. No firm explanations can be given to account for these results, due to a lack of research in this area. Possible mechanisms for the changes in sex ratio with flowers are discussed. This study demonstrated that flowers are an important source of nutrients for D. tasmanica, influencing the longevity, fecundity and offspring sex ratio of this species. However, only some of the field experiments were able to show any positive effect of the provision of floral resources on parasitoid abundance or parasitism rate. More information is needed on the role these parasitoids, and other natural enemies, play in regulating leafroller populations in New Zealand vineyards, and on how they use floral resources in the field, before recommendations can be made regarding the adoption of this technology by growers.

327	Diseño de un modelo para mejorar la competitividad de la cadena de suministro del sector florícola ecuatoriano Rodríguez Mañay, Luis Oswaldo 19 June 2023 (has links) [ES] Las exportaciones de Ecuador han estado caracterizadas por productos primarios (Petróleo crudo, banano y plátano, café, camarón, cacao, abacá, madera, atún, pescado, flores naturales) y por productos industrializados (derivados de petróleo, café elaborado, elaborados de cacao, harina de pescado, otros elaborados del producto del mar, químicos y fármacos, manufacturas de metales, sombreros, manufacturas de textiles). Las exportaciones de Ecuador en el período 2017-2021 han estado sobre los 20 mil millones de dólares, de los cuales el 80% corresponde a productos primarios y el 20% a productos industrializados. Dentro de los productos primarios la participación del petróleo crudo ha ido disminuyendo al pasar del 42% en el 2017 a 34% en el 2021, en cambio el resto de productos primarios ha pasado del 58% en el 2017 al 66% en el 2021. Estas cifras significan que la especialización de Ecuador es netamente agrícola. En este contexto la presente investigación titulada "Diseño de un modelo para mejorar la competitividad del sector florícola ecuatoriano" apunta a contribuir el sector agrícola ecuatoriano. Para el efecto el estudio contempló las siguientes investigaciones: a) Competitividad del sector florícola ecuatoriano, para lo cual se aplicó la metodología de Balassa, que determinó que Ecuador y Colombia tienen una fuerte ventaja comparativa en comparación con los países exportadores estudiados como son: Países Bajos, Kenia y Etiopía. Se concluye que Ecuador debe aplicar estrategias de marketing, como es el desarrollo del mercado, para lograr el posicionamiento de su exportación en la Unión Europea que en la actualidad es el principal mercado de flores cortadas del mundo. Otra estrategia que debe aplicar Ecuador es la diversificación relacionada que especifica que se debe aplicar la producción de flores cortadas hacia otras variedades como son crisantemos, claveles, flores y capullos, lirios y orquídeas, que actualmente forman parte del mercado mundial. b) Análisis comparativo de los modelos de la cadena de suministro: ABC, BSC y SCOR, se aplicó una revisión de la literatura, se encontró que el modelo SCOR es una herramienta muy poderosa para estructura, evaluar y comparar las prácticas y el desempeño de la cadena de suministro. El modelo SCOR propone un enfoque integrado que se basa en la concepción de una estructura interconectada que une procesos, incluye métricas de desempeño, mejores prácticas y tecnología con el objeto de la mejora continua de la cadena de suministro. c) Análisis de desempeño de la cadena de suministro del sector florícola ecuatoriano, por métricas, aplicando SCOR y AHP. Para este estudio se aplicó la metodología SCOR y AHP y dio como resultado que los procesos Devolución y Gestión registran las puntuaciones más bajas, y por lo tanto los agentes del sector florícola deberían trabajar más sobre estos procesos para su mejora. Del estudio realizado a la cadena de suministro del sector florícola ecuatoriano se concluye que el modelo SCOR junto con AHP constituyen una adecuada metodología para el análisis de la cadena de suministro del sector florícola, y particularmente del sector florícola ecuatoriano. Los resultados de este estudio muestran las posibilidades tan interesantes que se abren con la aplicación conjunta, para identificar los aspectos más críticos en la SC de un sector con el objeto de introducir mejoras. d) Análisis del desempeño de la cadena de suministro del sector florícola ecuatoriano, por procesos, subprocesos, actividades y tareas, aplicando SCOR y AHP. Se aplicó la metodología SCOR y AHP. Se determinó que de las 29 empresas estudiadas el desempeño tuvo como resultado el 85% de rendimiento calificándose como "bueno". La investigación contribuye a la literatura científica con una propuesta metodológica que utiliza el modelo SCOR con AHP para medir el rendimiento de la cadena de suministro. El modelo propuesto permite analizar el desempeño de la cadena de suministro a nivel sectorial. / [CA] Les exportacions de l'Equador han estat caracteritzades per productes primaris (Petroli cru, bananer i plàtan, café, gambeta, cacau, abacá, fusta, tonyina, peix, flors naturals) i per productes industrialitzats (derivats de petroli, café elaborat, elaborats de cacau, farina de peix, altres elaborats del producte de la mar, químics i fàrmacs, manufactures de metalls, barrets, manufactures de tèxtils). Les exportacions de l'Equador en el període 2017-2021 han estat sobre els 20 mil milions de dòlars, dels quals el 80% correspon a productes primaris i el 20% a productes industrialitzats. Dins dels productes primaris la participació del petroli cru ha anat disminuint en passar del 42% en el 2017 a 34% en el 2021, en canvi la resta de productes primaris ha passat del 58% en el 2017 al 66% en el 2021. Aquestes xifres signifiquen que l'especialització de l'Equador és netament agrícola. En aquest context la present investigació titulada "Disseny d'un model per a millorar la competitivitat del sector florícola equatorià" apunta a contribuir el sector agrícola equatorià. Per a l'efecte l'estudi va contemplar les següents investigacions: a) Competitivitat del sector florícola equatorià, per a això es va aplicar la metodologia de Balassa, que va determinar que l'Equador i Colòmbia tenen un fort avantatge comparatiu en comparació amb els països exportadors estudiats com són: Països Baixos, Kenya i Etiòpia. Es conclou que l'Equador ha d'aplicar estratègies de màrqueting, com és el desenvolupament del mercat, per a aconseguir el posicionament de la seua exportació a la Unió Europea que en l'actualitat és el principal mercat de flors tallades del món. Una altra estratègia que ha d'aplicar l'Equador és la diversificació relacionada que especifica que s'ha d'aplicar la producció de flors tallades cap a altres varietats com són crisantems, clavells, flors i capolls, lliris i orquídies, que actualment formen part del mercat mundial. b) Anàlisi comparativa dels models de la cadena de subministrament: ABC, BSC i SCOR, es va aplicar una revisió de la literatura, es va trobar que el model SCOR és una eina molt poderosa per a estructura, avaluar i comparar les pràctiques i l'acompliment de la cadena de subministrament. El model SCOR proposa un enfocament integrat que es basa en la concepció d'una estructura interconnectada que uneix processos, inclou mètriques d'acompliment, millors pràctiques i tecnologia amb l'objecte de la millora contínua de la cadena de subministrament. c) Anàlisi d'acompliment de la cadena de subministrament del sector florícola equatorià, per mètriques, aplicant SCOR i AHP. Per a aquest estudi es va aplicar la metodologia SCOR i AHP i va donar com a resultat que els processos Devolució i Gestió registren les puntuacions més baixes, i per tant els agents del sector florícola haurien de treballar més sobre aquests processos per a la seua millora. De l'estudi realitzat a la cadena de subministrament del sector florícola equatorià es conclou que el model SCOR juntament amb AHP constitueixen una adequada metodologia per a l'anàlisi de la cadena de subministrament del sector florícola, i particularment del sector florícola equatorià. Els resultats d'aquest estudi mostren les possibilitats tan interessants que s'obrin amb l'aplicació conjunta, per a identificar els aspectes més crítics en la SC d'un sector a fi d'introduir millores. d) Anàlisi de l'acompliment de la cadena de subministrament del sector florícola equatorià, per processos, subprocesos, activitats i tasques, aplicant SCOR i AHP. Es va aplicar la metodologia SCOR i AHP. Es va determinar que de les 29 empreses estudiades l'acompliment va tindre com a resultat el 85% de rendiment qualificant-se com a "bo". La investigació contribueix a la literatura científica amb una proposta metodològica que utilitza el model SCOR amb AHP per a mesurar el rendiment de la cadena de subministrament. El model proposat permet analitzar l'acompliment de la c / [EN] Ecuador's exports have been characterized by primary products (crude oil, bananas and plantains, coffee, shrimp, cocoa, cocoa, abaca, wood, tuna, fish, natural flowers) and industrialized products (petroleum derivatives, processed coffee, processed cocoa, fishmeal, other processed seafood, chemicals and pharmaceuticals, manufactured metals, hats, manufactured textiles). Ecuador's exports in the period 2017-2021 have been over US$20 billion, of which 80% corresponds to primary products and 20% to industrialized products. Within primary products the participation of crude oil has been decreasing going from 42% in 2017 to 34% in 2021, on the other hand the rest of primary products has gone from 58% in 2017 to 66% in 2021. These figures mean that Ecuador's specialization is purely agricultural. In this context, the present research entitled "Design of a model to improve the competitiveness of the Ecuadorian flower sector" aims to contribute to the Ecuadorian agricultural sector. For this purpose, the study contemplated the following research: a) Competitiveness of the Ecuadorian flower sector, for which the Balassa methodology was applied, which determined that Ecuador and Colombia have a strong comparative advantage compared to the exporting countries studied such as: Netherlands, Kenya and Ethiopia. It is concluded that Ecuador should apply marketing strategies, such as market development, to achieve export positioning in the European Union, which is currently the main market for cut flowers in the world. Another strategy that Ecuador should apply is related diversification, which specifies that it should apply the production of cut flowers to other varieties such as chrysanthemums, carnations, flowers and buds, lilies and orchids, which are currently part of the world market. b) Comparative analysis of supply chain models: ABC, BSC and SCOR, a literature review was applied, and it was found that the SCOR model is a very powerful tool for structuring, evaluating and comparing supply chain practices and performance. The SCOR model proposes an integrated approach based on the concept of an interconnected structure that links processes, includes performance metrics, best practices and technology for the purpose of continuous improvement of the supply chain. c) Performance analysis of the supply chain of the Ecuadorian flower sector, by metrics, applying SCOR and AHP. For this study, the SCOR and AHP methodology was applied and resulted in the Return and Management processes registering the lowest scores, and therefore the floriculture sector agents should work more on these processes for their improvement. From the study of the supply chain of the Ecuadorian flower sector, it is concluded that the SCOR model together with AHP is an adequate methodology for the analysis of the supply chain of the flower sector, and particularly of the Ecuadorian flower sector. The results of this study show the interesting possibilities opened up by their joint application to identify the most critical aspects of a sector's SC in order to introduce improvements. d) Analysis of the performance of the Ecuadorian flower supply chain, by processes, sub-processes, activities and tasks, applying SCOR and AHP. The SCOR and AHP methodology was applied. It was determined that of the 29 companies studied, the performance resulted in 85% of performance, qualifying as "good". The research contributes to the scientific literature with a methodological proposal that uses the SCOR model with AHP to measure supply chain performance. The proposed model allows the analysis of supply chain performance at the sector level. / Rodríguez Mañay, LO. (2023).

328	Whole Teachers: A Holistic Education Perspective on Krishnamurti‘s Educational Philosophy Rathnam, Anbananthan 09 August 2013 (has links) The purpose of this qualitative research study, which utilizes a phenomenological inquiry method, is to inquire into the awareness of what it means to be a whole teacher from the perspective of the philosophy of Jiddu Krishnamurti, a philosopher/spiritual teacher. Four participants (teachers) were interviewed from the Oak Grove School, an alternative, holistic school founded by Krishnamurti in 1974. This inquiry probed into teachers’ thinking, teachers’ lives, teachers’ inner lives, teachers’ contemplative practices, teachers’ calling/vocation and teachers’ pedagogy. The findings of this inquiry reveal the awareness that exists among the participants with regards to their understanding of Krishnamurti’s educational philosophy and the way in which this philosophy has shaped their lives and the lives of their students (both implicit- ly and explicitly) The findings from this research further show that Krishnamurti’s philosophy has certainly had an impact on the participants’ wholeness. Krishnamurti was never interested in imposing his philosophy on the teachers to think in a narrow groove. Rather, he challenged them to arrive at wholeness or a holistic approach towards living by their own volition, by putting aside all philosophy, including his own. This research points towards the possible ways in which wholeness can be developed using: Innate wisdom (teachers’ inner life, teachers’ calling); wisdom gained through experiencing life (teachers’ life, teachers’ thinking); wisdom gained through their teaching experience (teachers’ pedagogy) and wisdom gained through practices that bring harmony to the mind, body and spirit (teachers’ contemplative approaches). An experiential model titled, The Flower Model: An Experiential Metaphor – which integrates the three stages of awareness – was developed using Krishnamurti’s approach towards wholeness. This model can be used to guide teachers with their respective psychological conditionings that reside or exist in their thinking, lives, inner lives, contemplative practices, vocation and pedagogy/curriculum design.

329	Whole Teachers: A Holistic Education Perspective on Krishnamurti‘s Educational Philosophy Rathnam, Anbananthan 09 August 2013 (has links) The purpose of this qualitative research study, which utilizes a phenomenological inquiry method, is to inquire into the awareness of what it means to be a whole teacher from the perspective of the philosophy of Jiddu Krishnamurti, a philosopher/spiritual teacher. Four participants (teachers) were interviewed from the Oak Grove School, an alternative, holistic school founded by Krishnamurti in 1974. This inquiry probed into teachers’ thinking, teachers’ lives, teachers’ inner lives, teachers’ contemplative practices, teachers’ calling/vocation and teachers’ pedagogy. The findings of this inquiry reveal the awareness that exists among the participants with regards to their understanding of Krishnamurti’s educational philosophy and the way in which this philosophy has shaped their lives and the lives of their students (both implicit- ly and explicitly) The findings from this research further show that Krishnamurti’s philosophy has certainly had an impact on the participants’ wholeness. Krishnamurti was never interested in imposing his philosophy on the teachers to think in a narrow groove. Rather, he challenged them to arrive at wholeness or a holistic approach towards living by their own volition, by putting aside all philosophy, including his own. This research points towards the possible ways in which wholeness can be developed using: Innate wisdom (teachers’ inner life, teachers’ calling); wisdom gained through experiencing life (teachers’ life, teachers’ thinking); wisdom gained through their teaching experience (teachers’ pedagogy) and wisdom gained through practices that bring harmony to the mind, body and spirit (teachers’ contemplative approaches). An experiential model titled, The Flower Model: An Experiential Metaphor – which integrates the three stages of awareness – was developed using Krishnamurti’s approach towards wholeness. This model can be used to guide teachers with their respective psychological conditionings that reside or exist in their thinking, lives, inner lives, contemplative practices, vocation and pedagogy/curriculum design.
