O desenvolvimento de técnicas que proporcionem maiores produtividades é necessário para atender a crescente demanda por orgânicos. Portanto, objetivou-se avaliar a produtividade de tomate cereja em função do uso de mulching, calcário e esterco bovino em sistema orgânico. A pesquisa foi realizada no Centro de Ciências Agrárias e da Biodiversidade da Universidade Federal do Cariri, Crato-Ceará. Foram avaliados o comprimento e o diâmetro dos frutos, o número de frutos por planta, a massa por fruto, massa de frutos por planta e a produtividade. Os resultados evidenciaram efeito positivo do uso do calcário para elevação da saturação por bases a 80%, enquanto que o mulching não teve efeito significativo. Quanto à adubação orgânica com esterco bovino, apresentou resposta linear até a dose de 5 L por cova, com valores crescentes de produtividade. Conclui-se que o uso de calcário e esterco bovino beneficiam o desenvolvimento e produtividade do tomate cereja, enquanto o uso de mulching não melhorou o desempenho da cultura.

Published: December 2017

A alface é uma das hortaliças folhosas de grande importância comercial e de maior consumo em todo o mundo. Essa espécie apresenta grande resposta à adubação orgânica, sendo uma das fontes dos adubos orgânicas mais utilizadas na agricultura nordestina o esterco de animal, e na região do sertão paraibano, principalmente o ovino. A utilização do espaçamento adequado é determinante para que a planta possa expressar seu potencial produtivo nos diferentes sistemas de produção. Com o objetivo de avaliar o desenvolvimento da alface em relação a diferentes espaçamentos e a aplicação de doses de esterco ovino em ciclos subsequentes, foram conduzidos dois experimentos durante o período de outubro de 2012 à fevereiro de 2013, na área experimental da Universidade Federal de Campina Grande, localizada no município de Pombal, Paraíba. Em cada experimento os tratamentos avaliados foram: três espaçamentos (0,20 x 0,20; 0,20 x 0,25; 0,25 x 0,25 m) e quatro doses de esterco ovino (0; 20; 40 e 60 t ha-1 ). Foi adotado o delineamento experimental em blocos casualizados, com arranjo fatorial 3 x 4, sendo a três espaçamentos de cultivo e quatro doses de esterco ovino, com quatro repetições. Os maiores espaçamentos promoveram os melhores desenvolvimento e produção das plantas de alface, com valores superiores no segundo cultivo, demonstrando ação do efeito residual da aplicação do esterco ovino, principalmente nos tratamentos que receberam 60 t ha-1.

Published: December 2017

O estado do Ceará é um dos principais produtores e exportadores de frutas tropicais do Brasil. No entanto, os produtores têm alguns problemas relacionados com as moscas-das-frutas (Diptera: Tephritidae), pois estes tefritídeos causam danos aos frutos e a simples presença de algumas espécies dificulta a exportação de frutas in natura. No estado do Ceará são escassas as informações sobre as moscas-das-frutas e seus hospedeiros nas regiões produtoras de frutas, como por exemplo, na região do Baixo Jaguaribe. Esta região está localizada no semiárido brasileiro e é composta por dez municípios, entre eles o município de Quixeré. Portanto, o objetivo deste trabalho foi conhecer as espécies de moscas-das-frutas, seus hospedeiros e respectivos índices de infestação, em diferentes locais do município de Quixeré. Para isto, foram realizadas coletas aleatórias de frutos em diferentes frutíferas (nativas e exóticas), na zona rural e urbana de Quixeré. Os frutos coletados eram levados para o laboratório, onde eram contados, pesados e acondicionados em bandejas plásticas sobre uma camada de vermiculita. Após sete dias, a vermiculita era peneirada e os pupuários obtidos eram acondicionados em recipientes plásticos até a emergência dos adultos. Frutos de 21 espécies foram amostrados e apenas cinco estavam infestadas por moscas-das-frutas. As espécies obtidas foram Ceratitis capitata (Wiedemann), Anastrepha zenildae Zucchi, Anastrepha sororcula Zucchi e Anastrepha obliqua (Macquart). A goiaba Psidium guajava L. foi o fruto que apresentou os maiores índices de infestação.
Os entraves da tendência pragmática para uma educação ambiental emancipatória / The challenges of the pragmatic tendendy for emancipatory environmental education
Authors: Nogueira Liliane Samira Becari , Teixeira Catarina
Published: December 2017

Este artigo é um ensaio teórico fundamentado em autores que analisam as correntes e tendências político-pedagógicas da Educação Ambiental (EA). A discussão se apoia na ideia de crise ambiental da sociedade contemporânea e as compreensões acerca do conceito inerente ao termo “Desenvolvimento Sustentável”, característico da macrotendência pragmática. Discute-se as características de cada tendência da EA e os entraves do pragmatismo em contraposição a uma Educação Ambiental Emancipatória, tendo como referencial epistemológico e filosófico a Teoria Crítica. De forma geral, o pragmatismo se apresenta como um problema da Educação e, por consequência, da EA. A valorização do pragmatismo em detrimento do fazer permeado pelo pensamento crítico constitui um dos problemas da vertente hegemônica da EA. Embora haja um crescimento da vertente crítica da EA, a posição central dentro do campo ocupada atualmente pela tendência pragmática nos impõe uma Educação Ambiental incapaz de realizar o seu potencial emancipatório, por estar apoiada em práticas que não se orientam para a transformação das relações sociais vigentes.Palavras-chave: Educação Ambiental; Pragmatismo; Teoria crítica; Emancipação. ABSTRACT: The present article is a theoretical discussion based on authors who analyze current political-pedagogical trends of the Environmental Education. The discussion is substantiated on the idea of the modern society's environmental crisis and the understanding of the concept associated with the "Sustainable Development" term, representing a predominant pragmatic macrotendency in the Environmental Educational field. The article discusses the aspects of each Environmental Education tendency and the challenges of the pragmatism opposed to the Emancipatory Environmental Education idea, taking as a phisophical and as an epistemological reference the Critical Theory. In general, the pragmatism is presented as an educational problem and consequently an Environmental Educational issue. The appreciation of pragmatism compared to the devaluation of the acts reasoned on the assumptions of the critical thinking is one of the problems of the hegemonic strand of the Environmental Education. Although there is some growth of the critical strand of the Environmental Education, the central position in this field, currently occupied by the pragmactic tendency, imposes on us an Evironmental Education incapable of fulfilling its emancipatory potencial for being supported by practices that are not oriented towards the transformation of the current social relations.Keywords: Environmental education; Pragmatism; Critical theory; Emancipation.

Thus, based on the writing of the Guarani authors and my experimentation with the process of schooling that is taking place in their territories, i analyze how indigenous school curriculum policies, written and unwritten, have been organized to legislate conceptos known as interculturality, bilingualism, which have received new meanings and translation between the spells and invisible beings of Guarani shamanism.Keywords: Indigenous Intercultural Education; Cosmologies; Guarani -Mbyá population.
Paulo Freire antes de "Pedagogia do Oprimido", ou, de "Educação e atualidade brasileira" à "Educação como prática da liberdade" / Paulo Freire before "Pedagogy of the oppressed"...
Authors: Fonseca Sérgio C. , Pacifico Soraya Maria Romano
Published: December 2017

A obra de Paulo Freire é bastante lembrada a partir de trabalhos centrais no conjunto de suas produções, a exemplo de "Pedagogia do oprimido"; "Professora sim, tia não"; "Pedagogia da esperança" e "Pedagogia da autonomia", além de diversos outros títulos de sua autoria não menos importantes, porém, nem tão exitosos em termos de edições, traduções e publicações em outros países. Ademais, uma espécie de jargão freireano tem como fonte "Pedagogia do oprimido", a exemplo das expressões opressor, oprimido, educação bancária e educação libertadora. Em contraposição a essa fama vinda do início dos anos 1970, o propósito deste artigo é demonstrar que alguns conceitos e termos importantes como democracia, personalidade democrática, organicidade, fase de trânsito e rachadura foram elaborados por Paulo Freire em textos de sua juventude intelectual e que, além disso, foram importantes por contribuírem com as primeiras camadas de conceituação para obras que registraram a estabilização de alguns princípios importantes e constantes de Pedagogia do oprimido. Para tanto, foram tomadas como fonte uma série de artigos assinados por Paulo Freire e publicados no Diário de Pernambuco, em 1957, bem como sua tese doutoral "Educação e atualidade brasileira", de 1959, e "Educação como prática da liberdade", de 1967, com indicação em prefácio de elaboração em 1965.Palavras-chave: Paulo Freire; Democracia; "Educação e atualidade brasileira"; "Educação como prática da liberdade". ABSTRACT: The work of Paulo Freire is well known due to central books among the set of his papers, like "Pedagogy of the oppressed", "Teachers as cultural workers", "Pedagogy of hope" and "Pedagogy of autonomy", as well as several other titles that, despite their importance, are not so successful in terms of editions, translations and publications in other countries. In addition, a kind of Freirean jargon has as its source "Pedagogy of the oppressed", using expressions like oppressor, oppressed, banking model of education and liberating education. In contrast to this fame built in the early 1970s, the purpose of this article is to demonstrate that some important concepts and terms such as democracy, democratic personality, organicity, transit phase and crack were elaborated by Paulo Freire in his early texts, which were important for contributing to the first layers of conceptualization for works that consolidate some important principles of Pedagogy of the oppressed. In this article, thus, we use a series of articles published by Paulo Freire in Diário de Pernambuco in 1957 as well as his Ph.D. thesis entitled "Education and Brazilian actuality" (1959) and "Education as the practice of freedom" (1965-1967).Keywords: Paulo Freire; Democracy; "Education and Brazilian actuality"; "Education as the pratice of freedom".
Human Resource Quality and Household Income in North Sulawesi, Indonesia
Authors: Kindangen Paulus , Rotinsulu Tri Oldy , Murni Sri
Published: December 2017

Household income is a very important economic variable to measure purchasing power of household. The higher the household income the higher the purchasing power and, thus, the better is the level of needs fulfilment and the higher the level of economic well being or welfare. This research was conducted to find out the influence of human resource quality on household income. Household income is the total income (in rupiah) of a household in a year. The level of education and entrepreneurship were chosen as proxies of human resource quality; entrepreneurship is then represented by “commitment and perseverance”, “initiative and action”, as well as “adaptive ability”. This research was done in urban areas of North Sulawesi in the cities of Manado, Bitung, Tomohon, and Kotamobagu as well as Tahuna. Tahuna is the capital of Sangihe Archipelago Regency. The sample of this research consists of 340 households in with the heads of households and/or housewives were chosen as respondents. The respondents are the households of various main job: civil servant including teachers, business persons, farmers, and fishermen. The respondents were chosen purposively in order to be able to answer the questions in the questionnaire. Data analysis was conducted using multiple linear regression model. This research finds that education and entrepreneurship have simultaneous-positive influence on household income in North Sulawesi Province of Indonesia. Partially, every independent variable (the proxies), unless commitment and perseverance, has significant-positive influence on household income. This finding gives implication that it is very important to increase the quality of human resources – education and entrepreneurship – to increase income and, thus, economic welfare, of households in the region.
Doula Support During Childbearing—Aiming for the Best Birthing Experience: A Phenomenological Study
Authors: Brisco C. Michelle , Small Sandra P.
Published: December 2017

A growing body of evidence indicates that doula support improves childbirth outcomes. The purpose of this study was to examine women’s lived experience of such support. Hermeneutic phenomenology was used to carry out and analyze in-depth interviews with 14 women who had doulas for support during pregnancy, childbirth, and the immediate postpartum period. Six main themes were revealed. The women were aiming for the best birthing experience, and they believed to achieve this they needed extra support and to have a full say in their childbirth experiences. The doulas helped the women to have peace of mind prenatally, and all but one woman had an overall satisfying experience with their doulas. Whether satisfied or dissatisfied with their personal doulas, all the women believed that having a doula is valuable. However, choosing the right doula matters because a comfortable relationship between a woman and her doula is essential to achieving the best birthing experience. Health care providers and policymakers must recognize the importance women place on constant and personalized support during childbirth and endeavor to provide such care.

However, this device is still underused in this center. In this case report, a 65-year old male patient with triple vessel disease (chronic total occluded left anterior descending artery-LAD, and significant stenoses of left circumflex and right coronary arteries), low ejection fraction and preprocedure blood pressure, was reported to have IABP support applied before PCI. The intervention to penetrate the occluded LAD was not success. After procedure, the patient was observed in intensive care unit. Weaning of IABP was performed after about 30 hours usage, without complication.
ROLE OF IMMUNOGLOBULIN G (IgG) FROM THE INDUCTION OF Escherichia coli PILI ADHESION PROTEIN ISOLATED FROM INFERTILE MALE SEMEN WITH 32.2 KDA MOLECULAR WEIGHT AS OPSONIN AND ANTI-ADHESION AN IN VITRO Escherichia coli INFECTION
Authors: Sukarjati Sukarjati , Amilah Susie
Published: December 2017

Escherichia coli (E. coli), a major cause of male genital tract infections, is asymptomatic and may result in male infertility. We have succeeded in isolating and characterizing proteins of E. Pili coli isolates from semen of infertile men who function as adhesin with a molecular weight (MW) 32.2 kDa. This study aims to prove the ability of IgG results adhesion proteins induced pili of E. MW coli 32.2 kDa as opsonin to determine the value of the activity and phagocytic capacity and as an anti- adhesion by calculating the average number of E. coli that attached to human spermatozoa. E. coli infertile men's semen were cultured using standard bacteriology. Peritoneal macrophages were isolated from mice. Spermatozoa from donors were prepared using Sil with Select Plus. IgG was obtained from mice immunized with (1) PBS (control), (2) E. coli pili adhesion protein isolated from infertile men semen with MW of 32.2 kDa and (3) weakened E. coli isolated from infertile men's semen. Phagocytic activity value was determined by counting the number of cells activated macrophage phagocytosis process in 100 cells. Phagocytic capacity value was determined by counting the number of bacteria ingested by 25 macrophages. Anti-adhesion test was done by counting the number of bacteria attached to 100 spermatozoa. The results of this study showed difference (p=0.000) in phagocytic activity and phagocytic capacity (p=0.000) between treatment (1) and (2), and between treatment (1) to (3). However, treatment (2) and (3) did not differ neither in phagocytic activity (p=0.693) nor in phagocytosis capacity (p=0.125). Anti-adhesion test produces difference (p=0.000) in the number of E. coli that attached to human spermatozoa between treatments (1) and treatment (2), and between treatments (1) and (3). The number of E. coli that attached to human spermatozoa between treatment (2) and treatment (3) was not significantly different (p=0.371). In conclusion, IgG from the induction of E. coli pili adhesion protein of infertile men semen isolates with MW of 32.2 kDa can increase phagocytic activity and capacity as well as serve as an anti- adhesion. Thus, IgG from the induction of E. coli pili adhesion protein of infertile men semen isolates with MW of 32.2 kDa is protective against in vitro E. coli infection, so that it can be used as material to prevent male reproductive tract infections due to E. coli.

The area of fresh water swampy land in Lampung in 2012 was 55,714 ha with rice productivity of 5.13 t/ha so it is possible to be increased. The article discusses opportunity to increase rice production in fresh water swampy land in Lampung. Increasing rice yield can be done by enhancing cropping index and land productivity, lowering yield gap and decreasing yeld loss. Cropping index in fresh water swampy land can be increased by cultivating rice with surjan system, while rice yield is increased by integrated crop management (ICM) which its components include the use of improved varieties, planting with legowo 2: 1 or 4: 1, fertilizer application according to plant need, water management to prevent rice plant from submerging or drought, and integrated pest management. Rice yield gap is decreased by implementing location specific technologies and intensifying counseling to farmers, while yield loss is lowered by applying integrated pest management and using agricultural tools and machineries in rice farming. These production increases have an impact on the regional and national food availability in an effort to achieve rice self-sufficiency.

ABSTRAK

Luas lahan rawa lebak di Provinsi Lampung pada tahun 2012 mencapai 55.714 ha dengan tingkat produktivitas padi 5,13 t/ha sehingga masih berpeluang ditingkatkan. Tulisan ini membahas peluang peningkatan produksi padi di lahan rawa lebak di Lampung. Peningkatan produksi dapat dilakukan melalui peningkatan indeks pertanaman (IP) dan produktivitas lahan, mengurangi senjang hasil, dan menurunkan kehilangan hasil. Indeks pertanaman di lahan rawa lebak dapat ditingkatkan dengan menerapkan sistem surjan. Sementara produktivitas ditingkatkan melalui pengelolaan tanaman terpadu (PTT) dengan komponen teknologinya antara lain penggunaan varietas unggul baru, cara tanam legowo 2:1 atau 4:1, pemberian hara sesuai kebutuhan tanaman, pengelolaan tata air sehingga tanaman padi terhindar dari terendam atau kekeringan, serta pengelolaan hama dan penyakit secara terpadu. Penurunan senjang hasil dapat dilakukan dengan menerapkan teknologi spesifik lokasi dan mengintensifkan penyuluhan ke petani. Sementara kehilangan hasil dapat dikurangi melalui penerapan pengelolaan hama dan penyakit secara terpadu dan penggunaan alat dan mesin pertanian pada kegiatan usaha tani. Peningkatan produksi ini akan berdampak pada peningkatan ketersediaan pangan daerah dan nasional dalam upaya mencapai swasembada beras.

Tanaman hydraulic lift (HL) dilaporkan dapat memasok air pada tanaman lain di sekitarnya saat periode kekeringan. Hasil studi sebelumnya menunjukkan jambu mete memiliki kemampuan HL, namun belum diketahui potensi pasokan airnya. Penelitian ini dilakukan di komplek rumah kaca Cimanggu antara Mei-November 2016 dengan tujuan mengevaluasi kemampuan pasokan air dari hydraulic lift jambu mete pada periode kekeringan dan efeknya terhadap status air jaringan jagung yang tumbuh di sekitarnya. Jambu mete varietas B-02 dan jagung varietas Lamuru ditanam berdampingan pada pot dengan desain khusus, yang diatur dalam tiga kondisi perlakuan, yakni selalu berkecukupan air (B), kekeringan tanpa ada akses HL jambu mete (K), dan kekeringan dengan akses HL jambu mete (H). Ketiga perlakuan kondisi tanaman tersebut ditempatkan di rumah kaca dalam rancangan acak kelompok dengan sembilan ulangan. Hasil penelitian menunjukkan HL jambu mete dapat memasok air pada jagung, sehingga pada periode kekeringan tingkat lanjut, lengas tanahnya menjadi lebih tinggi ± 2,5% dibandingkan jagung tanpa akses HL jambu mete. Adanya pasokan air tersebut menyebabkan status air jaringan jagung selama periode kekeringan menjadi lebih baik dengan tingkat penurunan nilai dari kondisi kecukupan air pada potensial air daun, transpirasi, dan fotosintesis berturut-turut hanya sekitar 30%, 36%, dan 32%, dibandingkan penurunan nilai tersebut pada kondisi tanpa akses HL jambu mete yang mencapai 40%, 70%, dan 66%. Hasil penelitian ini memperlihatkan pasokan air pada jagung oleh HL jambu mete cukup efektif pada periode kekeringan, dan membantu meringankan efek stres kekeringan pada jagung sehingga dapat memelihara status air jaringannya tetap baik.

This paper analyzes the quality of governance and financial assistance as key determinants for successful functioning of the process of integration within the European Union (EU). Moreover, the paper develops a comparison of the Western Balkans with current EU members and the forthcoming, on the basis of the selected indicators of governance (rule of law, democracy, corruption, political stability, and effectiveness of state) with the experience of the implementation of the reforms of public administration. Various surveys show that the Western Balkans, by all quality of governance indicators, especially in the rule of law, lags behind 28 (twenty eight) of the current EU countries (without taking in account the Great Britain). The low level of the functioning of rule of law, combined with inadequate and unreformed public administration is potentially the biggest obstacle in the association agreement of the Western Balkans with EU, but also as challenge in achieving sustainable social and economic development.Whereas in the case of the Western Balkan countries, there is an obvious difference between proclaiming and internal reality, which is further compounded by a difficult political and economic transition, as well as in social domain - where poverty and corruption are the most worrying. The research data obtained from independent bodies - academic and research institutions, civil society and international organizations - confirm this controversial picture of the Western Balkans. Negative attitudes still prevail in Western Balkans political elites and if given the chance to political manipulation, may behave unpredictably. All this makes it obligatory to make a comparative overview, for depicting in particular the quality of governance as sine qua non for the Western Balkans countries‘ integration in EU.

L’attenzione alla componente pragmatica nell’ambito dell’apprendimento e dell’insegnamento dell’italiano come lingua seconda è un fenomeno molto giovane, che si sta però sviluppando con una certa vivacità: nasce da qui l’idea di dedicare un numero monografico di E-JournALL alla pragmatica dell’italiano L2/LS. In questo contributo introduttivo si offre una panoramica degli studi che, a partire dagli anni Duemila, si sono occupati di apprendimento, insegnamento e uso dell’italiano L2/LS in relazione a fenomeni pragmatici, con particolare attenzione alle due aree tematiche che hanno ricevuto maggiore attenzione: la realizzazione di atti linguistici e i segnali discorsivi utili alla gestione della testualità e dell’interazione. Si propone poi una rapida ricognizione di ricerche che affrontano altri ambiti tematici connessi alla pragmatica dell’italiano L2, come per esempio la struttura informativa degli enunciati o i meccanismi che regolano la conversazione. A conclusione di questa panoramica si mostrerà come i lavori raccolti nel presente numero speciale si inseriscono nel quadro delineato contribuendo ad ampliare la ricerca sulla pragmatica dell’italiano L2/LS.
