Inter-relação da produtividade de madeira do pinus com atributos físico-químicos de um latossolo do cerrado brasileiro

Com relação aos atributos do solo, a produtividade de madeira do pinus varia substancialmente em função do pH, do teor de matéria orgânica e da resistência à penetração. No ano de 2007, no Município de Selvíria (MS) foi analisada a produtividade de madeira do Pinus caribaea var. hondurensis, em função de alguns atributos físico-químicos de um Latossolo Vermelho Distrófico estabelecido num maciço florestal com 21 anos de idade. O objetivo foi selecionar, entre os atributos pesquisados do solo, aquele que melhor se apresentasse para explicar a variabilidade da produtividade de madeira. Para tanto, foi instalado um grid geoestatístico, para a coleta dos dados do solo e da planta, contendo 121 pontos amostrais, numa área de 3 ha do referido maciço. A produtividade de madeira variou diretamente com o pH do solo, tanto linear quanto espacialmente, com valores de 27,0-32,6 m³ ha-1 ano-1 e 3,9-4,4, respectivamente. Nos maiores, 32,6-36,9 m³ ha-1 ano-1 e 4,4-4,9. Dessa forma, o pH revelou ser um apreciável indicador da qualidade química do solo quando o objetivo foi estimar, linear e espacialmente, a produtividade de madeira da essência florestal pesquisada nas condições do Cerrado brasileiro do Sudeste do Estado do Mato Grosso do Sul.

Management of commercial property derived risks in the market context of the Russian Federation

The objective of the thesis is to examine the current state of risk management and to determine an appropriate risk management policy for commercial property derived risks in the Russian branch of a Finnish retail trade company. The employed research methodologies are comparative in-depth interviews and empirical value at risk analysis, including portfolio risk decomposition to determine the inter-currency characteristics. For a multinational retail trade company, the commercial property derived risks open up as a diverse combination of financial and non-financial risks with four distinctive interest groups. The research results indicate that geographical diversification across currency regimes provides diversification benefits. The Russian ruble is the most significant single risk component when considering the net investments outside the euro-zone. Decreasing the Russian ruble and Swedish krona exposures are the most effective methods to reduce translation derived risk. Exchange rate volatility varies over time according to idiosyncratic currency regime characteristics, and cost-effective risk management requires comprehensive analysis of the business environment. Profound and proactive risk management methods are found to be pivotal for companies with cross-border operations in order to succeed among international competitors.

Laparoscopic resection of the left lateral segment of the liver in donors of living liver transplantation. The authors present a case of laparoscopic resection of the left lateral segment of the liver in a donor of living liver transplantation. The procedure was done in six hours and the left lateral segment of the liver was removed through a 15 cm right subcostal incision. The patient was discharged on the 5th post-operative day. A 40 mL intrabdominal collection of bile was percutaneously drained guided by ultra-sonography. The drain was removed after five days. Afterwards, the patient had good recovery with no other complication.

Índice de líquido amniótico: variabilidade inter e intra-observador

Objetivo: demonstrar a variação interobservador da medida ultra-sonográfica do índice de líquido amniótico (ILA) e da medida da área dos bolsões, bem como realizar uma comparação entre estes dois parâmetros. Além disto, procurou-se estabelecer a variação intra-observador existente na medição deste índice. Métodos: foram estudados os valores do ILA, como descrito por Phelan et al.18 , de um grupo de oitenta gestantes, consideradas clinicamente normais, atendidas na Escola de Ultra-sonografia e Reciclagem Médica Ribeirão Preto e no Departamento de Ginecologia e Obstetrícia da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (FMRP - USP). Todas as gestantes apresentavam idade gestacional acima de 24 semanas. Deste grupo, cinqüenta pacientes submeteram-se à avaliação do ILA por cinco ultra-sonografistas diferentes, com o uso do mesmo equipamento e no mesmo período de tempo, procurando-se estabelecer a variação interobservador deste índice. Além disto, foi realizada a medida planimétrica da área por parte de dois destes cinco ultra-sonografistas escolhidos aleatoriamente, na tentativa de verificar a variação interobservador na medida da área. Outro grupo composto por trinta gestantes foi avaliado por um mesmo observador ultra-sonografista na tentativa de se realizar a avaliação da variação intra-observador na medição do ILA. Resultados: observamos uma variação interobservador significante na medição do ILA e significante na medição da área. Não obstante, a variação intra-observador na medida do ILA foi considerada não-significante. Houve uma correlação entre as medidas do ILA e da área. Conclusões: o ILA apresenta maior aplicabilidade em relação à medida da área, além da maior facilidade de obtenção.

Acantose nigricante: inter-relações metabólicas inerentes à síndrome dos ovários policísticos

OBJETIVO: Estabelecer a prevalência da acantose nigricante (AN) no contexto da síndrome dos ovários policísticos (SOP) e as respectivas associações com a obesidade, a resistência insulínica (RI), a insulinemia e a síndrome metabólica (SM).MÉTODOS: Em um estudo transversal e prospectivo, foram selecionadas cem pacientes acometidas pela SOP, diagnosticadas segundo o Consenso de Rotterdam (2003). O exame cutâneo incluiu, além da verificação da presença da AN, a presença do hirsutismo (escore ≥8) e da acne. Foram investigados os dados clínicos e bioquímicos, os fatores de risco cardiovascular que se fazem presentes na SM, como circunferência abdominal (CA), obesidade, hipertensão e os índices de HDL e triglicérides. O modelo de aferição da resistência insulínica foi realizado por meio do teste homeostatic model assessment of insulin resistance(HOMA-IR).RESULTADOS: A prevalência da AN (53%) mostrou correspondência significativa com o hirsutismo (p=0,02), o índice de massa corpórea (IMC) (p<0,01), a insulinemia basal (p<0,01), o HOMA-IR (p<0,01) e a SM (p<0,05). A SM alcançou a prevalência de 36% e associou-se significativamente apenas com a AN (p<0,01). Conquanto ausente o diabetes mellitus, sobressaem as conotações do HOMA-IR alterado (p=0,01) com a SM (p<5%) e a AN (p<0,01).CONCLUSÕES: A AN integra o quadro fenotípico grave da SOP como mais um signo previsível dos riscos da doença cardiovascular.

Translation and Cross-Cultural Adaptation of the Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema into Portuguese Language

Objective The objective of the study is to describe the process of translation and cross-cultural adaptation of the Lymphoedema Functioning, Disability, and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) into (Brazilian) Portuguese. Methods The process was comprised of five steps - translation, back translation, revision by an expert panel, pretest, and final translation. The first translation was performed by two professionals of the healthcare area, and the back translation was performed by two translators. An expert panel assessed the questions for semantics and idiomatic, cultural, and conceptual equivalence. The pretest was conducted on 10 patients with lymphedema. Results Small differences were identified between the translated and back-translated versions, which were revised by the expert panel. The patients included in the pretest found 10 questions difficult to understand; these questions were reassessed by the same expert panel. Conclusion The results of the translation and cross-cultural adaptation of the Lymph- ICF-LL resulted in a Brazilian Portuguese version, which still requires validation with various samples of the local population.

Trust in inter-organisational dyadic relationships

Understanding the trust in organisations and the business relationships have been an emerging trend in past years. Researchers and executives and subject matter experts in companies have recognised the importance of managing the trust in inter-organisational relationships. Further, the interest both in academia and in business has raised an interest to under-stand dyadic relationships. The objective of this thesis was to examine trust in inter-organisational and inter-personal dyadic relationships. Trust and the dyadic relationships were analysed in information technolo-gy services and outsourcing industry. Dyads were established between the supplier company operating in the industry and its customers. The empiric part of the study was carried out by an email survey that was sent to 331 respondents resulting with effective response rate of 48.7 per cent. Statistical analyses were applied to analyse the data sample. In general, results indicated reputation, trustworthiness, capability and collaboration in dyadic trust relationships. Experience grown in duration of the relationship affected the trust positively. No drastic differences in trust were recognised when comparing supplier and customer responses.

Mapping the translation needs and practices in development co-operation projects of NGOs

Tämän pro gradu -tutkielman aiheena on kääntäminen ja viestintä vieraalla kielellä Suomen ulkoasiainministeriön rahoittamissa kansalaisjärjestöjen kehitysyhteistyöhankkeissa. Tutkielman on tarkoitus kartoittaa kyseisten kehitysyhteistyöhankkeiden kääntämiseen ja vieraskieliseen viestintään liittyviä tarpeita ja -käytäntöjä. Aihetta ei ole tutkittu laajasti muutoin, joten empiirinen osuus on erityisen merkittävässä roolissa. Tutkielman alussa esitellään ulkoasiainministeriön laatimia suomalaisten kansalaisjärjestöjen kehitysyhteistyöhankkeiden ehtoja ja ohjeita, jotka ovat kyseiselle tutkimukselle olennaisia. Tutkielman teoreettinen osuus koostuu lähinnä metodologisesta pohdinnasta, koska aiempaa tutkimustietoa on vähän. Tutkimusmetodien analysointia on painotettu myös siksi, että empiirisellä osuudella on niin suuri merkitys. Tutkielman empiirinen aineisto on yhtäältä peräisin tutkijan havainnoista, jotka saatiin omia varhaisempia hankehallinnointikokemuksia hyödyntäen sekä osallistuvan havainnoinnin menetelmää käyttäen kahden opiskelijajärjestön kehitysyhteistyöhankkeista vuosien 2009 ja 2012 välisenä aikana. Toisaalta aineisto on kerätty kyselytutkimuksen vastauksista. Kysely lähetettiin 35 suomalaiselle kansalaisjärjestölle, joiden kehitysyhteistyöhankkeita Suomen ulkoasiainministeriö rahoittaa. Järjestöt valittiin satunnaisotannalla. Empiirisen aineiston analyysistä ilmeni muun muassa, että tutkijan alkuperäinen hypoteesi kehitysyhteistyöhön liittyvien tekstien kääntämisen yleisyydestä pitää osittain paikkansa, vaikka tekstejä käännettiinkin kansalaisjärjestöissä vähemmän kuin tutkija odotti. Tutkimusaineisto ei ole kuitenkaan tarpeeksi laaja, jotta tuloksia voitaisiin yleistää, sillä kansalaisjärjestöt, niiden hankkeet, käännöstarpeet ja asiantuntemus osoittautuivat odotetusti hyvin erilaisiksi. Tulokset sisältävät asiaa myös esimerkiksi järjestöissä kääntävien ja vieraalla kielellä viestivien taustoista. Jatkotutkimukset ovat kuitenkin tarpeen, ja mahdollisia tutkimusaiheita on runsaasti.

Towards Inter-organizational Working Capital Management

Working capital is an investment which is tied up into the inventories and accounts receivable and which is released with accounts payable. Due to the current business landscape with tightened financial conditions and finance markets, organizations emphasize efficient working capital management. With efficient working capital management, a company can reduce the need of finance, free up cash, increase profitability, improve liquidity, increase the efficiency of operations, and decrease (financing) costs. From the perspective of an individual company, efficient working capital management means decreasing inventory levels by shortening the cycle time of inventories, decreasing accounts receivable by shortening the trade credit terms and effective collection procedures, and increasing the level of accounts payable by paying the suppliers later. From an inter-organizational perspective, however, working capital should not be sub-optimized by a single company but holistic view to working capital management through the supply chain should be adopted to create value and improve performance together. The purpose of this research is to take academic research as well as practical management towards inter-organizational working capital management. The thesis discusses the benefits as well as mechanisms of working capital management in the inter-organizational context and has two main objectives: (1) to examine the effect of inter-organizational working capital management on performance in the value chain context and (2) to develop models of working capital management for internal as well as inter-organizational value chains. The results of the archival research conducted in the value chain of the pulp and paper industry and the value chain of the automotive industry indicate that companies can increase relative profitability by managing working capital comprehensively by taking into account all three components, and holistically though the value chain. Companies in the value chain benefit from different strategies in working capital management depending on the position of the company in the value chain. This can be taken into account in inter-organizational working capital management. The effects of inter-organizational working capital management actions on the financing costs of working capital were studied via simulations. Simulations also show that the value chain and individual companies benefit from an inter-organizational view to working capital management. Inter-organizational working capital management actions include for example: shortening the cycle time of inventories, reducing product costs, shifting inventories, shortening payment terms, and considering the cost of capital. The thesis also provides solutions for the practical requirements for tools to control working capital. The design science part of the research introduces the adjusted cash conversion cycle (ACCC) model for internal value chains, as well as models for working capital management in the inter-organizational value chain context: the working capital management model (WCMM) and the financial cycle time model (FCTM) designed in corporation and product levels respectively. This research contributes to literature on working capital management and interorganizational accounting. The research gives a holistic, inter-organizational view to the management of working capital. It advances the knowledge in working capital management on operational level, increases knowledge in the recently risen theme of supply chainoriented, collaborative working capital management, combines management accounting research with supply chain management research, and contributes to the demand of practical inter-organizational accounting methods. In addition, the research has strong practical focus as new managerial methods are introduced.

Estudo de competição inter e intraespecífica envolvendo Glycine max (L. ) Merril e Cyperus rotundus (L.), em condições de casa de vegetação

O presente experimento teve por objetivo estudar os efeitos da competição inter e intraespecífica envolvendo Glycine max (L.) Merril e Cyperus rotundus L. sobre as características das plantas e acúmulos de N, P, K, Ca e Mg pelas espécies envolvidas. Para tanto, estipulou-se um tratamento em que se desenvolveram três plantas de Glycine max e outro em que se desenvolveram 3 tubérculos de Cyperus rotundus por vaso. Para estudar os efeitos da competição intraespecífica, em dois outros tratamentos dobraram-se as populações por vaso. No estudo da competição interespecífica permitiu-se o desenvolvimento de três plantas de Glycine max e de três tubérculos de Cyperus rotundus num mesmo vaso. De uma maneira geral, pôde-se observar que principalmente devido às diferenças no hábito de crescimento das duas espécies, a expressão da competição inter e intraespecífica, em cada uma delas, assume aspectos distintos. No caso de Cyperus rotundus, o efeito do dobro da densidade pôde ser compensado, em parte, pela maior produção de manifestações epígeas e de tubérculos, aliados ao maior desenvolvimento dos tubérculos na menor densidade de plantio. No caso da competição interespecífica, os resultados sugerem um efeito decisivo do sombreamento de Leguminosae sobre o comportamento da Cyperaceae. Os padrões de efeitos da competição pelos nutrientes foi determinado também pelas diferenças no recrutamento dos elementos do solo pelas espécies envolvidas.

GROWTH AND YIELD RESPONSE OF MAIZE (Zea mays) TO INTER AND INTRA-ROW WEED COMPETITION UNDER DIFFERENT FERTILIZER APPLICATION METHODS

A field experiment was conducted for two consecutive years to study the effect of fertilizer application methods and inter and intra-row weed-crop competition durations on density and biomass of different weeds and growth, grain yield and yield components of maize. The experimental treatments comprised of two fertilizer application methods (side placement and below seed placement) and inter and intra-row weed-crop competition durations each for 15, 30, 45, and 60 days after emergence, as well as through the crop growing period. Fertilizer application method didn't affect weed density, biomass, and grain yield of maize. Below seed fertilizer placement generally resulted in less mean weed dry weight and more crop leaf area index, growth rate, grain weight per cob and 1000 grain weight. Minimum number of weeds and dry weight were recorded in inter-row or intra-row weed-crop competition for 15 DAE. Number of cobs per plant, grain weight per cob, 1000 grain weight and grain yield decreased with an increase in both inter-row and intra-row weed-crop competition durations. Maximum mean grain yield of 6.35 and 6.33 tha-1 were recorded in inter-row and intra-row weed competition for 15 DAE, respectively.
