Potencial das terras do Projeto Jequitaí (MG) para o cultivo de cana-de-açúcar sob três sistemas de irrigação.

Os zoneamentos agroecológicos são modelos de pacotes tecnológicos que contêm recomendações para o uso sustentável dos recursos naturais e têm sua aplicação mais oportuna na agricultura irrigada, onde é maior a intensidade de uso destes recursos, principalmente o solo. A metodologia do Sistema Brasileiro de Classificação de Terras para Irrigação (SiBCTI) teve por finalidade o desenvolvimento de uma sistemática adaptada à realidade brasileira, constituindo um sistema de suporte à decisão para subsidiar zoneamentos agroecológicos voltados a esta temática. O objetivo deste estudo foi avaliar o potencial de terras para irrigação na área do Projeto Jequitaí (MG) por meio do SiBCTI. A utilização do SiBCTI na área deste projeto indicou, no sistema de irrigação localizado, um total de 8.584 ha de terras classificadas na classe a1. No sistema de irrigação por aspersão, as terras enquadradas na classe a1 alcançaram apenas 2.635 ha; e para o sistema de irrigação superfície não houve indicação de terras enquadradas nesta classe. O resultado geral da utilização do SiBCTI para o Projeto Jequitaí mostrou haver, tanto para o sistema por aspersão quanto para localizada, um total de 39.839 ha de terras consideradas irrigáveis. Os principais fatores limitantes para os sistemas localizado e aspersão foram o pH em água e a capacidade de água disponível. Considerando o sistema por superfície, os principais fatores limitantes foram a capacidade de água disponível e a velocidade de infiltração.

Irrigação na cultura do chuchu.

A presente publicação tem por objetivo orientar produtores e técnicos ligados à produção de chuchu sobre procedimentos e informações técnicas simples e atuais sobre os principais sistemas de irrigação e métodos de manejo da água que podem ser usados com sucesso na cultura.

Análise hidráulica de um sistema de irrigação por aspersão do tipo canhão hidráulico.

Este trabalho teve como objetivo calcular a uniformidade de irrigação para sistema de irrigação por aspersão do tipo canhão hidráulico submetido a vários espaçamentos em campo. Foi conduzido na propriedade hidroagrícola Lagoa do Ouro, no Município de Jequié, Bahia. O aspersor utilizado é do tipo canhão hidráulico, Plona-PLN 25. Foram utilizados 80 coletores no campo espaçados de 6 (m) para coleta das lâminas de água (mm). A evapotranspiração potencial da cultura foi medida a partir do tanque classe "A" instalado na propriedade. Os maiores valores apresentados de coeficientes de uniformidade CUC e CUD foram de 78% e 71% respectivamente para o espaçamento de 36x36 m; e os menores, 67% e 30% para o espaçamento 42x42 m.

SPOŁECZNO-KULTUROWE UWARUNKOWANIA PRZĘPSTW PRZECIWKO WOLNOŚCI SEKSUALNEJ MAŁOLETNIEGO

Wykorzystanie seksualne dziecka jest związane z przestępstwami z art. 200 i z kilku artykułów pokrewnych polskiego Kodeksu karnego. Czynniki społeczno-kulturowe oddziaływają na to zjawisko poprzez dwa rodzaje socjalizacji. Socjalizacja wtórna zachodzi w populacji polskiej w sposób jednolity dla wszystkich sprawców, natomiast różnicuje ich socjalizacja pierwotna, w związku z czym to ona winna być przedmiotem badań. Najlepsze wyjaśnienia zjawiska oferują ujęcia zintegrowane, akcentujące, między innymi, rolę czynników rodzinnych w jego powstawaniu. W niniejszym artykule, jako teoretyczną podstawę badań, wykorzystano zintegrowaną teorię etiologii przestępstw seksualnych, która uznaje rodzinne doświadczenia sprawcy za główną przyczynę późniejszego seksualnego wykorzystywania dzieci. Zaproponowano cztery ścieżki rozwoju patologii wskazujące, w jaki sposób wczesne uwarunkowania psychologiczne (typ opieki i postawy rodziców) przyczyniają się do zostania sprawcą wykorzystania seksualnego dziecka w przyszłości, oraz zweryfikowano je w badaniach własnych. Wyniki przeprowadzonych badań częściowo potwierdzają zaprezentowany model teoretyczny i pozwalają wyznaczyć kierunki dalszych poszukiwań.

Małżeństwa wiejskie w Polsce lat osiemdziesiątych. Szkic historyczny

In the article I present the structure of rural marriage in Poland of the 80-ies. I analyse basic factors of marriage mating, especially the reasons for getting married. Among the most important reasons are: love, material reasons, friendship, prestige, social position, sex. The article includes also the results of the research on marriage durability (stability), and also on factors influencing the marriage success or failure.

TCP Control Groups: Aggregated Congestion Control for TCP (MA Thesis)

This thesis presents a framework for aggregated congestion management for TCP flows and shows how to integrate such an approach in an existing TCP protocol stack. The thesis presents an initial implementation of this congestion management scheme in Linux, with performance evaluation in ns as well.

Covert conversations: disciplined improvisation and meaning-making in the masters (MA) supervisory relationship

This research asks the question: “What are the relational dynamics in Masters (MA) supervision?” It does so by focusing upon the supervisory relationship itself. It does this through dialoguing with the voices of both MA supervisors and supervisees in the Humanities using a Cultural Historical Activity Theory (CHAT) framework. In so doing, this research argues for a re-evaluation of how MA supervision is conceptualised and proposes a new theoretical framework for conceptualising MA supervision as a relational phenomenon. The research design was derived from an Activity Theory-influenced methodology. Data collection procedures included the administration of Activity Theory Logs, individual semi-structured interviews with both supervisors and supervisees and the completion of reflective journals. Grounded Theory was used to analyse the data. The sample for the study consists of three supervisor-supervisee dyads from three disciplines in the Humanities. Data was collected over the course of one academic year, 2010-2011. This research found that both individual and shared relational dynamics play an important role in MA supervision. Individual dynamics, such as supervisors’ iterative negotiation of ambiguity/clarity and supervisees’ boundary work, revealed that both parties attempt to negotiate a separation between their professional-academic identities and personal identities. However, an inherent paradox emerged when the shared relational dynamics of MA supervision were investigated. It was found that the shared space created by the supervisory relationship did not only exist in a physical setting, but was also psychoactive in nature and held strong emotional resonances for both parties involved. This served to undermine the separation between professional-academic and personal identities. As a result, this research argues that the interaction between the individual and shared relational dynamics in MA supervision enables, for both supervisors and supervisees, a disciplined improvisation of academic identity.

Sustainable Value Added - ein neues Maß des Nachhaltigkeitsbeitrags von Unternehmen am Beispiel der Henkel KGaA

This article introduces a new approach to measure corporate contributions to sustainability called Sustainable Value Added. Existing approaches to measure sustainability are based on a comparative assessment of environmental and social burdens and can thus be characterised as burden-based approaches. However, these approaches suffer from severe limitations as a comparative assessment and aggregation of all relevant environmental and social burdens fails in practice. In contrast to these burden-based approaches Sustainable Value Added is value-based. It determines the value that is created by the reduced or increased use of different environmental and social resources. For this purpose the use of environmental and social resources is valued at their opportunity cost. Sustainable Value Added allows an integrated assessment of the economic, environmental, and social performance of a company and expresses the corporate contribution to sustainability in a single monetary indicator. This article explains the theoretical background of Sustainable Value Added, relates it to existing approaches to measure sustainability, and - using the example of Henkel KGaA - demonstrates its practical applicability.
