A concentração da indústria de frigoríficos e a crise da pecuária na região sudeste do Pará: uma abordagem multifacetada

O presente estudo analisa as raízes da crise de 2008 na pecuária paraense, enfocando o conflito entre pecuaristas e frigoríficos a partir de uma abordagem multifacetada. Tendo como hipótese inicial o desequilíbrio entre oferta e demanda de gado, o estudo está dividido em duas partes, onde, na primeira, é pesquisada a pecuária em si, quanto à discussão científica sobre a sua viabilidade na Amazônia e sua evolução recente no estado do Pará. Na segunda parte, trata-se da instalação da grande indústria de frigoríficos na Sudeste paraense, o aumento da capacidade de abate e o desequilíbrio com a oferta de gado bovino. No contexto desse desequilíbrio, são avaliadas tanto as causas externas, tais como a exportação de gado vivo e a crise financeira internacional, quanto domésticas, em particular a atuação das organizações não governamentais, das políticas públicas e do relacionamento entre pecuaristas e frigoríficos. O estudo conclui que a crise foi causada por um conjunto de fatores estruturais e conjunturais. Os fatores conjunturais inserem-se no contexto da inserção da pecuária paraense no mercado internacional, afetado pela crise financeira internacional, pela exportação de bovinos vivos e pela política industrial do Governo Federal. Os fatores estruturais são aqueles relacionados à estrutura fundiária concentrada e ao modelo de pecuária extensiva instalada na região, ainda marcado por infrações das leis ambientais e trabalhistas, e pela relação de desconfiança entre pecuaristas e frigoríficos, onde o mercado ainda não foi capaz de criar uma estrutura de governança onde os agentes possam equacionar seus problemas.

Pecuária e desmatamento: uma análise das principais causas diretas do desmatamento na Amazônia

Na Amazônia Brasileira a principal atividade responsável pelo desmatamento é a pecuária. Esse trabalho analisa a evolução das causas imediatas do desmatamento da Amazônia, utilizando-se de regressões lineares com dados em painel. O modelo avalia a contribuição dos principais usos do solo na região ao desmatamento, de 2000 a 2006. Dados do PRODES de desmatamento, o número de cabeças bovinas de 782 municípios da Amazônia e área plantada de culturas perenes e temporárias foram utilizados para essa análise. O resultado mostrou que o desmatamento é fortemente correlacionado com a pecuária. A soja também aparece positivamente correlacionada com o desmatamento. Esta tendência é reforçada pelo crescimento nacional e internacional da demanda de carne. Políticas públicas eficazes para a redução do desmatamento devem, portanto, agir nas causas subjacentes da expansão da pecuária reduzindo a força dos processos que produzem a sua expansão na fronteira do desmatamento.

EFFECTS OF EMERGENCY IN BIOSTIMULANT SEEDLING OF PASSION FRUIT ROXINHO OF KENYA

The increase in market demand for fresh fruits along with the high price of passion fruit juice in domestic and international markets has increased the interest in fruit, especially the purple passion fruit in the center south of the country seeking to export. This study aimed to evaluate the effects of plant growth regulator on the emergence and development of seedlings of passion 'Roxinho of Kenya' when propagated sexually. The treatments consisted of concentrations of commercial product Stimulate (R): control (no biostimulant); 6; 12; 18; 24 and 30 mL. kg(-1) of seed. It were evaluated the percentage of seedling emergence, number of leaves, aerial part dry weight, stem and root (g), root length (mm), diameter and stem length (mm), leaf area and chlorophyll 'a' and 'b'. The application of bio-stimulant in doses of 6 and 12 mL. kg(-1) promotes increased percentage of seedling emergence of Passiflora edulis Sims in a shorter time. The use of it also promotes the development of seedlings, with better results for the dose of 12 and 24 mL. kg(-1) treated seeds.

As organizações e a ISO 26000: revisão dos conceitos, dos motivadores e das barreiras de implementação

ISO 26000, published in 2010, focuses on corporate social responsibility. This study presents a systematic review conducted in ISI Web of Knowledge (Web of Science) and Elsevier's Scopus databases to answer the following question: What are the barriers and motivators affecting the adoption of ISO 26000 by organizations? The articles were selected using filters that applied two inclusion criteria. The data were summarized in a table covering the concepts of ISO 26000, the motivators, and the barriers. The motivators were globalization or competition in international markets, congruence with management systems, reputation or image, relationship with employees and improvement of the organizational environment, improvement in the relationship with external stakeholders, competitive advantage and strategy, guide to corporate social responsibility (CSR), and reduction of business risks. The barriers were lack of alignment between CSR and organizational strategy; business (national and international); unfamiliarity with ISO 26000; lack of communication, tools and sensitivity to the subject; short-term focus; knowledge management; fear of not fulfilling the standard; and financial resources. Finally, an agenda for future studies was prepared.

Estudo geofísico em um depósito de manganês supergênico no município de Itapira - SP

The mining research is a complex activity, which should preferably involve the combination of direct and indirect techniques of geological research. The increasing demand for base metals in domestic and international markets provide the revaluation of mineral occurrences, which can be converted into deposits and mines. This paper presents the results of the application of geophysical methods of electric resistivity and induced polarization in main foliation parallel to the arrangement of the area, in a deposit of oxides and hydroxides in massive and disseminated ores, docked in gneisses and quartzites, located in the municipality of Itapira, in the North of the State of São Paulo in Brazil. Inversion models indicate the predominance of high cargabilidade that partially coincide with low resistivity values. Integration of geophysical data made possible the drafting of sections of electric walking with cross-checking distance x depth, for detailing your target. The integrated analysis of geophysical and geological structural data leads to the conclusion that the primary mining suffers structural control with the regional foliation in ores

Marcadores discursivos: uma proposta lexicográfica

Spanish is a language that in recent years has been growing in importance both politically and socially and economically, since some of the major international markets such as Chile, Spain, Mexico and Argentina, among many, have this language as the official language. This fact motivated us to conduct research that could, in some way, contribute to the teaching of this language in Brazil. Thus under the aegis of the theories and practices of bilingual lexicography, we seek to describe and analyze the treatment that some Spanish - Portuguese bilingual dictionaries present in our market give to the sentence connectors. From a textual corpus selected the markers and observe how the dictionaries analyzed work with this type of unit. We found that the information contained in these lexicographical works is not sufficient to meet the needs of Brazilian learners. Then, we proposed a macrostructure of a passive bilingual dictionary of sentence connectors in the language pair Spanish - Portuguese. Our research aims to contribute to bilingual lexicography both in regard to theoretical and methodological reflections on the application of these theories. Our contribution aims to fabricate materials for the teaching of Spanish in Brazil

Estudo e análise estatística no mercado de ações brasileiro

The objective of this paper is to verify and analyze the existence in Brazil of stylized facts observed in financial time series: volatility clustering, probability distributions with fat tails, the presence of long run memory in absolute return time series, absence of linear return autocorrelation, gain/loss asymmetry, aggregative gaussianity, slow absolute return autocorrelation decay, trading volume/volatility correlation and leverage effect. We analyzed intraday prices for 10 stocks traded at the BM&FBovespa, responsible for 52.1% of the Ibovespa portfolio on Sept. 01, 2009. The data analysis confirms the stylized facts, whose behavior is consistent with what is observed in international markets.

Is production the core competence for the internationalization of emerging country firms?

The rise of new multinationals in countries like Brazil provides an opportunity to revisit and carefully construct theories of how firms internationalize, a topic on which extant theory is weak. Brazilian firms are "infant multinationals", unlike developed country firms that are "mature multinationals". They are also internationalizing in a very different global context, and can do so on the basis of different competitive advantages than multinationals that came before. Therefore, this study aims at creating subsidies for theory building about early-stage internationalization. Emerging country firms have Production competences as main competitive asset to internationalize, what reflects their competitive positioning in home markets and their entry strategy in international markets. In the case of early-entrants - Western multinationals in the 1950s and Japanese in the 1980s - the Production competence played a key role for successful internationalization. Thus, the focus of the study is the role that the Production competence plays in the internationalization of late-entrants, the emerging country multinationals. The research design considers not only the position of the headquarters but also the initiatives of the subsidiaries and the dynamic interplay between both. The paper allows a better understanding of internationalization processes and the role of Production, when firms start building their own international networks. It brings relevant insights about the paths that are being followed by emerging country multinationals, the difficulties they find, the solutions they develop. These are important inputs not only for new theory building but also for managerial practice. (C) 2012 Elsevier B.V. All rights reserved.

Trends, drivers and impacts of changes in swidden cultivation in tropical forest-agriculture frontiers: A global assessment

This meta-analysis of land-cover transformations of the past 10-15 years in tropical forest-agriculture frontiers world-wide shows that swidden agriculture decreases in landscapes with access to local, national and international markets that encourage cattle production and cash cropping, including biofuels. Conservation policies and practices also accelerate changes in swidden by restricting forest clearing and encouraging commercial agriculture. However, swidden remains important in many frontier areas where farmers have unequal or insecure access to investment and market opportunities, or where multi-functionality of land uses has been preserved as a strategy to adapt to current ecological, economic and political circumstances. In some areas swidden remains important simply because intensification is not a viable choice, for example when population densities and/or food market demands are low. The transformation of swidden landscapes into more intensive land uses has generally increased household incomes, but has also led to negative effects on the social and human capital of local communities to varying degrees. From an environmental perspective, the transition from swidden to other land uses often contributes to permanent deforestation, loss of biodiversity, increased weed pressure, declines in soil fertility, and accelerated soil erosion. Our prognosis is that, despite the global trend towards land use intensification, in many areas swidden will remain part of rural landscapes as the safety component of diversified systems, particularly in response to risks and uncertainties associated with more intensive land use systems.

Development of a supplier and purchase order management product/service under the 4PL logistics concept: a case study

Supply chain starts with a demand arisen and ends with material transport and delivery at its final destination. With this in mind, most of manufacturing, processors or distribution companies of consumer goods, spare parts and components for production, processing and finished goods, within national or international markets, may not have information and control over its supply chain performance. This article presents concept and logistics models evolution, purchase order and international supplier management, control tower and its logistics information systems. This also presents a real process implementation for a global high tech manufacturer company.

All'origine dello squilibrio di potere negoziale della parte agricola nella food supply chain: il caso della suinicoltura in Emilia-Romagna

Il settore suinicolo ricopre un ruolo rilevante nel contesto nazionale, con ricadute economiche e sociali di primaria importanza in varie regioni. Tuttavia da alcuni anni il settore si trova in crisi a causa dell’instabilità dei mercati internazionali, dello scarso coordinamento tra gli attori della filiera, della progressiva riduzione della redditività dei prodotti trasformati a Denominazione di Origine, della mancata valorizzazione dei tagli di carne fresca, nonché della difficoltà di aggredire i mercati esteri. Altre criticità riguardano la distribuzione del valore lungo la filiera e la scarsa efficacia delle politiche di coordinamento finora adottate. L'obiettivo della ricerca è quello di identificare gli elementi che possono garantire maggiore equilibrio di potere negoziale tra allevatori suinicoli e macellatori rispetto alla situazione attuale: verificati gli elementi critici che caratterizzano la relazione commerciale tra allevatori e macellatori, si avanzano alcune proposte operative utili al superamento delle fratture tra la componente agricola e quella dei macelli in Emilia Romagna. La struttura della tesi è la seguente: (capitolo 1) si descrive il quadro economico del settore suinicolo a livello internazionale e nazionale. Successivamente (capitolo 2) si passano in rassegna le teorie economiche utili a comprendere le ragioni alla base del malfunzionamento dei rapporti tra gli attori della filiera agroalimentare, mentre nel terzo capitolo è richiamato il quadro normativo comunitario, nazionale e regionale all’interno del quale tali relazioni si configurano. Nel quarto capitolo si elabora un modello interpretativo al fine di spiegare le fratture che oggi contraddistinguono le relazioni in essere tra gli attori della filiera: il “modello delle fratture”. Alla luce di questa concettualizzazione è stata svolta un’indagine diretta svolta presso gli operatori aderenti all’Organizzazione Interprofessionale del Gran Suino Italiano, i cui risultati hanno consentito di valutare l’efficacia del modello interpretativo e di fornire indicazioni migliorative della strategia di governance delle relazioni tra allevatori e macellatori.

L'internazionalizzazione e le specializzazioni commerciali delle regioni italiane nel settore agroalimentare

Il presente lavoro si compone di tre capitoli, tra loro autonomi e allo stesso tempo intrinsecamente collegati. Nel primo capitolo si è voluto offrire una panoramica dello scenario agroalimentare italiano e della sua rilevanza nel sistema economico nazionale. Per fare ciò si è partiti da una disamina del contesto economico mondiale per poi centrare il discorso sull’andamento congiunturale dell’agroalimentare nazionale, analizzato secondo i principali indicatori macroeconomici. Successivamente vengono presentati gli attori del sistema agroalimentare, rilevando per ciascuno di essi le proprie specificità e tendenze. L’ultima parte del primo capitolo è un focus specifico sul ruolo giocato dall’agroalimentare italiano nel commercio e nei mercati internazionali. Nel secondo capitolo si è approntata una mappatura territoriale e per comparti delle principali specializzazioni commerciali del settore agroalimentare delle regioni italiane. Tramite l'utilizzo di appositi indici di specializzazione si è analizzata la realtà agroalimentare delle regioni italiane, mettendone in evidenza la struttura competitiva e approssimandola tramite l’analisi dei vantaggi comparati di cui gode. Infine, nel terzo capitolo, si è ampliato il campo d'analisi tentando di misurare il livello di internazionalizzazione delle regioni italiane, non solo in ambito agroalimentare, ma considerando l'intero sistema territoriale regionale. Si è tentato di fare ciò tramite tre strumenti: l’analisi delle componenti principali (PCA o ACP), il Mazziotta-Pareto Index e il Wroclaw taxonomic method. I risultati ottenuti tramite le tre modalità di elaborazione hanno permesso di approfondire la conoscenza del livello di internazionalizzazione registrato dalle regioni italiane, mettendo in luce ulteriori filoni di ricerca della tematica osservata.
