    Water scarcity is the most severe constraint for agricultural growth in arid and semi-arid areas. To overcome this, there is a need to use the scarce water efficiently and economically which is an important strategy to address present and future water need. This study was conducted from December 2017 to March 2018 in Ambo District, aiming to investigate the effect of deficit irrigation at different growth stages on yield and water productivity of onion. The experiment was laid out in randomized completed block design with three replications and nine treatments namely, T1: control (without deficit irrigation at any growth stage – 100% crop evapotranspiration, ETc); T2: 20% deficit irrigation in all growth stages – 80% ETc; T3: 40% deficit irrigation in all growth stages – 60% ETc; T4: 20% deficit irrigation in development and late stages – 80% ETc, and 40% deficit irrigation in mid stage – 60% ETc; T5: 20% deficit irrigation in development and late stages – 80% ETc, and 40% deficit irrigation in initial stage – 60% ETc; T6: 20% deficit irrigation in initial stage – 80% ETc; T7: 20% deficit irrigation in development stage – 80% ETc; T8: 20% deficit irrigation in mid stage – 80% ETc; T9: 20% deficit irrigation in late stage – 80% ETc. The results indicated that deficit irrigation levels at different growth stages had significantly (p ≤ 0.05) affected the yield and water productivity of onion. The highest marketable yield (28.68 ton ha-1) was obtained from 20% deficit irrigation at late stage (T9), whereas lowest yield (14.42 ton ha-1) was recorded from 40% deficit irrigation in all growth stages (T3). The mean values of onion yield obtained in T2, T6, T8, and T9 no differ statistically. The highest water productivity (8.77 kg m-3) was obtained in T2 (20% deficit in all growth stages), while the lowest water productivity (5.17 kg m-3) was obtained in T4 (20% deficit irrigation at development and late stages, and 40% deficit irrigation at mid stage). These results confirmed that with deficit irrigation practice it is possible to increase water productivity by saving water and increase income from scarce water. Therefore, it was recommended that the application of deficit irrigation in 20% of crop water requirement throughout season in four days irrigation interval is beneficial for obtaining optimum onion yield and increases water productivity

    This research aimed to investigate the scientific technological interest of 14 native and endemic species in Brazil that have proven their traditional use. We researched species in Brazil that have proven their traditional use. We researched species published in five popular booklets that represent Brazilian regions and biomes. The research was divided into three stages. In the first one, we investigated the geographic distribution and endemism of the selected species through and endemism of the selected species through the Flora do Brazil platform. In the second stage, we verified the number of records and the number of collections of the species, through the Species link plat formant the third was carried out through a search in the Scopus, web of science and Leans databases, available in the capes periodicals database (www.periodicos.capes.gov.br) in order to investigate the technological indicators. We conclude that the more wide spread the traditional knowledge of certain species, the grater the interest in research that provers its effectiveness. The preservation of traditional knowledge of the use of medicinal plants depends on the dissemination of this knowledge and the promotion of research involving species that have proven popular use.  We understand that traditional knowledge is also important for industries, because although a species does not present scientific studies or patents, in can present an expressive record of traditional knowledge.Esta pesquisa teve como objetivo investigar o interesse científico e tecnológico de 14 espécies nativas e endêmicas do Brasil que têm o seu uso tradicional comprovado.  Foram pesquisadas espécies publicadas em cinco cartilhas populares que representam as regiões e os biomas brasileiros. A pesquisa foi dividida em três etapas. Na primeira  investigamos a distribuição geográfica e o endemismo das espécies selecionadas através da plataforma Flora do Brasil. Na segunda etapa, foi verificado o número de registros e número de coletas das espécies, através da plataforma Spcieslink e a terceira foi feita através de uma pesquisa nas bases Scopus, Web of Science e Lens, disponíveis na base periódicos capes (www.periodicos.capes.gov.br), afim de investigar os indicadores tecnológicos. Concluímos que quanto mais difundido o conhecimento tradicional de certas espécies, maior o interesse nas pesquisas que comprovem a sua eficácia. A preservação do conhecimento tradicional do uso de plantas medicinais depende da difusão deste conhecimento e do fomento a pesquisas envolvendo as espécies que têm o seu uso popular comprovado. Compreendemos que o conhecimento tradicional também é importante para as indústrias, pois embora uma espécie não apresente estudos científicos ou patentes, ela pode apresentar um expressivo registro de conhecimento tradicional.

    Infinito y Teoría social: Tarde como lector de Leibniz

    Full text link
    The text analyzes the fundamental principles around which Gabriel Tarde builds his approach to social life. This perspective, elaborated towards the end of the 19th century, is remarkably displaced with respect to both the holisms and the individualisms that dominated the social sciences and the humanities during the following century. One of the main reasons for this is that his philosophical starting point was not Kant, Hegel or Marx, but Leibniz. Tarde elaborates a (neo) monadological social theory. That is, he produces an infinitist conception of the social articulated around an ontology and an epistemology of infinitesimals and their associated concepts. This is what the paper intends to show.El texto analiza los principios fundamentales en torno a los cuales Gabriel Tarde construye su aproximación a la vida social. Esta perspectiva, elaborada hacia fines del siglo XIX, se encuentra notablemente descentrada tanto respecto de los holismos como los individualismos que dominaron las ciencias sociales y las humanidades durante el siglo siguiente. Una de las principales razones de ello es que su punto de partida filosófico no fue Kant, Hegel o Marx, sino Leibniz. Tarde elabora una teoría social (neo) monadológica.

    Os usos políticos da dialética hegeliana

    Full text link
    This article seeks to present the different political uses of the Hegelian dialectic that we can find within the left-wing critical tradition, the so-called “Hegelian left”. Hegel had a profound impact on political thought ever since his work began to circulate within the intellectual spheres of old Europe. Marx was the main heir of the Hegelian dialectic in the 19th century. But contemporarily, authors such as Slavoj Zizek and the Brazilian Vladimir Safatle continue the Hegelian tradition of the left. Thus, the impact of the Hegelian dialectic within the contemporary political debate has not ceased to produce reverberations. However, there is the question of whether the left-wing critical tradition's use of the Hegelian dialectic is a use that can be considered legitimate if we start from Hegel's own thought. In our work, we will investigate whether the use of Hegel's thought by the left-wing critical tradition is a legitimate use when compared with the Hegelian philosophical enterprise itself.O presente artigo busca apresentar os distintos usos políticos da dialética hegeliana que podemos encontrar dentro da tradição crítica de esquerda, a chamada “esquerda hegeliana”. Hegel teve um profundo impacto no pensamento político desde que sua obra começou a circular dentro das esferas intelectuais da velha Europa. Marx foi o principal herdeiro da dialética hegeliana no século XIX. Mas contemporaneamente, autores como Slavoj Zizek e o brasileiro Vladimir Safatle dão continuidade à tradição hegeliana de esquerda. Sendo assim, o impacto da dialética hegeliana dentro do debate político contemporâneo não cessou de produzir reverberações. Contudo, existe a questão de se o uso que a tradição crítica de esquerda fez da dialética hegeliana é um uso que pode ser considerado legítimo se partirmos do pensamento do próprio Hegel. Em nosso trabalho, investigaremos se o uso do pensamento de Hegel por parte da tradição crítica de esquerda é um uso legítimo quando comparado com o próprio empreendimento filosófico hegeliano

    La máquina de hacer pan: un análisis del conocimiento tácito involucrado en el ejercicio de habilidades prácticas y el comportamiento de artefactos

    Full text link
    In the late 1980s, Matsushita Electric Industrial Co. Ltd. released the first home-use bread making machine. Its launch was so successful that knowledge sociologists undertook the task of analyzing the knowledge involved in its design and production. To accomplish this, Takeuchi and Nonaka (1995) extensively examined the concept of tacit knowledge (POLANYI, 1966/2009). They argued that engineers and developers managed to articulate and translate the tacit knowledge inherent in the skilled practice of a master baker into the design of the bread-making machine, reproducing the same practical outcome. In the present study, I will discuss their interpretation of the notion of tacit knowledge and contend that the tacit knowledge involved in the exercise of practical skills cannot be articulated and translated into the design of the bread making machine without losing, at the very least, a substantial portion of those skills. To support this argument, I will draw on contributions from the sociology of science and phenomenology to argue that the tacit knowledge embedded in the skilled practice of our master baker depends on a familiarity relationship with the environment. This relationship is epistemically relevant insofar as it involves aspectual representations of our environment, which guide the actions of our master baker. In contrast, the bread making machine lacks such representations and, as a result, cannot involve, at the very least, the same type of tacit knowledge as a guide for its behavior.A finales de la década de los ‘80, Matsushita Electric Industrial Co. Ltd. largó a la venta la primera máquina panificadora de uso doméstico. Su lanzamiento gozó de tal éxito, que sociólogos del conocimiento se abocaron a analizar el conocimiento involucrado en su diseño y producción. Para ello, Takeuchi y Nonaka (1995) analizaron detalladamente la noción de conocimiento tácito (POLANYI, 1966/2009). Defendieron que los ingenieros y desarrolladores lograron explicitar y traducir el conocimiento tácito presente en el ejercicio habilidoso del maestro panadero al diseño de la máquina de hacer pan, reproduciendo el mismo resultado práctico. En el presente trabajo, discutiré su interpretación de la noción de conocimiento tácito y defenderé que el conocimiento tácito involucrado en el ejercicio de habilidades prácticas no puede explicitarse y traducirse en el diseño de la máquina de hacer pan sin perder, al menos, una parte sustancial de dichas habilidades. Para ello, me valdré de aportes de la sociología de la ciencia y de la fenomenología para argumentar que el conocimiento tácito involucrado en el ejercicio habilidoso de nuestro maestro panadero depende de una relación de familiaridad con el entorno. Dicha relación es epistémicamente relevante en la medida en que involucra representaciones aspectuales de nuestro entorno, las cuales permiten guiar la acción de nuestro maestro panadero. A diferencia, la máquina de hacer pan no posee tales representaciones y, en consecuencia, no puede implicar, al menos, el mismo tipo de conocimiento tácito como guía de su comportamientoA finales de la década de los ‘80, Matsushita Electric Industrial Co.

    Ethiopia is developing countries which haven’t access to better water sources and over 75 to 85% people lack basic sanitation. Transition towards more sustainable urban water management is an urgent need since the scarcity of water has been a major challenge around the world. Supporting such a transition requires the development of alternative methods such as rainwater harvesting (RWH) system, recycling, desalination, wastewater reuse, etc. With the help of a systematic the study critically examined the major developments taken place in Haramaya watershed in the RWH system, measuring the RWH awareness index and identifying the implementation challenges and provides managerial solutions. With the help of an explanatory research design, quantitative analysis was conducted collecting both primary and secondary data. Semi-structured questionnaires were used as research instruments and 403 households (203 users and 200 non-users of the RWH system) of Haramaya watershed were interviewed. Measuring the awareness index in users and the non-users of the RWH system in terms of the four dimensions namely, financial, socio-environmental, technical and institutional, it is found that the user groups are more aware of the issues of climate change than the non-users. Around 70% of the respondent suggested that continuous monitoring, user’s self-commitment, cost-friendly technology, pollution control, among others can help to address the RWH system challenges. The current government strategy should be focused on knowledge/capacity building and structural improvements of RWH, and this gap can be fulfilled via an updated RWH system

Serão abordados aspectos referentes à visibilidade, ao alcance, ao impacto, ao ineditismo da iniciativa bem como às dificuldades de viabilidade e ao descompasso entre itens do edital. Busca também dar destaque a determinados modos de funcionamento das instituições de ensino que de alguma forma reproduzem, reforçam, atualizam o chamado racismo estrutural, mesmo que nos últimos anos muito se tenha avançado. Ao final, aponta sugestões, renova convicções, procura diálogo com pares e fomenta esperança

    Deleuze e seu outro

    Full text link
    The concept of the other (autrui) did not receive due attention in Deleuze's philosophy as a whole until recently (VENTURA, 2020; FERREIRA, 2021). The Other appears in Deleuze’s work in some moments of Difference and Repetition, in What is philosophy? – a work written together with Félix Guattari – but, above all, in a text present in the appendix of Logic of Sense entitled “Michel Tournier and the world without others”, in which he comments the M. Tounier’s novel, Friday or the pacific limbo. The Other is nothing but the expression of a possible world, or even a structure that organizes perception and ensures the margins and transitions of the world. When this structure dissolves, the simulacra ascend to the surfaces, destroying the forms and releasing the forces and intensities. We believe that the agent of this dissolution is Friday, whose coming disrupts the order forged by Robinson on his island. Friday no longer functions as the structure-other, since it is another of the Other, which will allow access to an impersonal, pre-individual transcendental field, populated by free singularities. Emmanuel Lévinas's concepts of “face” and “wholly other” (tout autre) will help in this movement in order to understand Deleuze's other, although it is necessary to point out its pertinence and its limitations.O conceito de outrem (autrui) não recebeu a devida atenção no conjunto da filosofia de Deleuze até recentemente (VENTURA, 2020; FERREIRA, 2021). Outrem aparece na obra deleuziana em alguns momentos de Diferença e Repetição, em O que é a filosofia? – obra escrita juntamente a Félix Guattari – mas, sobretudo, num texto presente no apêndice de Lógica do sentido intitulado “Michel Tournier e o mundo sem outrem”, no qual ele comenta o romance de M. Tournier, Sexta-feira ou os limbos do pacífico. Outrem nada mais é do que a expressão de um mundo possível, ou ainda, uma estrutura que organiza a percepção e assegura as margens e transições do mundo. Quando esta estrutura se dissolve, os simulacros ascendem às superfícies, destruindo as formas e libertando as forças e intensidades. Acreditamos que o agente dessa dissolução é Sexta-feira, cuja vinda desarranja a ordem forjada por Robinson em sua ilha. Sexta-feira já não funciona como a estrutura outrem, visto que ele é um outro de outrem, que vai possibilitar o acesso a um campo transcendental impessoal, pré-individual, povoado de singularidades livres. Os conceitos de Emmanuel Lévinas de “rosto” e “absolutamente outro” (tout autre) auxiliará nesse movimento a fim de compreender o outro de Deleuze, embora seja necessário apontar a sua pertinência e as suas limitações
