A cadeia produtiva do marolo na região Sul de Minas Gerais. Repositório Alice
REZENDE, M. L.; MALAFAIA, G. C..
O presente trabalho tem como objetivo identificar os mecanismos envolvidos na produção e comercialização do marolo, na região de Alfenas, Minas Gerais. Foram entrevistadas no total 70 pessoas, entre produtores rurais, fabricantes de produtos a base de marolo e comerciantes. Os resultados encontrados evidenciam a precariedade do sistema de produção e comercialização do marolo, com predominância do extrativismo, venda informal dos frutos e processamento artesanal de produtos elaborados a partir do mesmo. Por outro lado, demonstram também o potencial dessa cultura como forma de complementar a renda dos pequenos produtores da região. Assim, torna-se necessária a busca por padrões de eficiência técnica e econômica da produção do marolo e seus derivados, além da...

A call for disruptive innovation in science publishing with a new open data-sharing platform for the life sciences Nature Precedings
Donald C. Cooper.
“A disruptive innovation is an innovation that helps create a new market and value network, and eventually goes on to disrupt an existing market and value network (over a few years or decades), displacing an earlier technology. The term is used in business and technology literature to describe innovations that improve a product or service in ways that the market does not expect.” -Wikipedia
On April 3rd, 2012 Nature Precedings, Nature Publishing Group’s experiment in free pre-print publishing was shut down and no longer accepts submissions. According to the Nature Precedings website it was created in 2007 as “a place for researchers to share documents, including presentations, posters, white...

A Case for Developing Place-Based Fire Management Strategies from Traditional Ecological Knowledge Ecology and Society
Ray, Lily A; Department of Geography, Clark University; Resilience and Adaptation Program, University of Alaska, Fairbanks ; lray@kawerak.org; Kolden, Crystal A; Department of Geography, University of Idaho; ckolden@uidaho.edu; Chapin III, F. Stuart; Institute of Arctic Biology, University of Alaska, Fairbanks ; terry.chapin@alaska.edu.
Sustainability science promotes place-based resource management because natural processes vary among ecosystems. When local science is limited, land managers may be forced to generalize from other ecosystems that function differently. One proposed solution is to draw upon the traditional ecological knowledge that indigenous groups have accumulated through resource use. Integrating traditional ecological knowledge with conventional resource management is difficult, especially when the two offer competing explanations of local environments. Although resource managers may discount traditional ecological knowledge that contradicts conventional resource management, we investigate the possibility that these disagreements can arise when nonlocal resource...

A Case Study of Technological Switching and Technological Lock-In in the French Fisheries Sector: Why is Sustainable Change so Difficult? ArchiMer
Le Floc'H, Pascal; Daures, Fabienne; Guyader, Olivier; Wilson, James.
Many sectors such as the fishery show classic examples of technological lock-in and path dependence, even though some economists might predict smooth switching toward technologies that are more cost effective and sustainable. We use ideas from the evolutionary economics and public choice literatures to explain why trajectories of technological change, especially in fisheries, may not be smooth at all, but rather punctuated. The interest of technological change and switching behavior for fisheries economists and managers stems from the fact that control of effective effort, often necessary for sustainable management of the resource, remains a central management problem for that sector worldwide, even in developed countries. However, various policies put in...

A cell junction pathology of neural stem cells leads to abnormal neurogenesis and hydrocephalus Biol. Res.
Rodríguez,Esteban M; Guerra,María M; Vío,Karin; González,César; Ortloff,Alexander; Bátiz,Luis F; Rodríguez,Sara; Jara,María C; Muñoz,Rosa I; Ortega,Eduardo; Jaque,Jaime; Guerra,Francisco; Sival,Deborah A; Dunnen,Wilfred F. A. den; Jiménez,Antonio J; Domínguez-Pinos,María D; Pérez-Fígares,José M; McAllister,James P; Johanson,Conrad.
Most cells of the developing mammalian brain derive from the ventricular (VZ) and the subventricular (SVZ) zones. The VZ is formed by the multipotent radial glia/neural stem cells (NSCs) while the SVZ harbors the rapidly proliferative neural precursor cells (NPCs). Evidence from human and animal models indicates that the common history of hydrocephalus and brain maldevelopment starts early in embryonic life with disruption of the VZ and SVZ. We propose that a "cell junction pathology" involving adherent and gap junctions is a final common outcome of a wide range of gene mutations resulting in proteins abnormally expressed by the VZ cells undergoing disruption. Disruption of the VZ during fetal development implies the loss of NSCs whereas VZ disruption...

A Censored Demand System Analysis of Fruits and Vegetables by Different Income Groups Using Micro Data AgEcon
Niu, Luyuan; Wohlgenant, Michael K..
This study examines demand for fruits and vegetables segmented by income levels in a complete demand system framework using the Consumer Expenditure Survey (CEX) from 2002 to 2006. Results show that disparities are found between high-income households and low-income households. Seasonal effects and demographic variables, such as household heads’ race and gender, region, household size and household composition, play an important role in fruit and vegetable consumption for both categories of household. In contrast, urban status, household heads’ educational level and age are not found to have a statistically significant impact for low-income households. Conditional price elasticities indicate that processed fruits and vegetables, fresh fruits and fresh...

A characterization of Chilean farmers based on their market-production orientation Ciencia e Investigación Agraria
Echeverría,Rodrigo; Moreira,Víctor; Barrena,José; Gopinath,Munisamy.
Chile's open trade policy, implemented during the last few decades, has greatly transformed Chilean farmers and their production systems. As a result, farmers can be grouped into three categories based on their market-production orientation: domestic, transitional or export producers. The objective of this paper is to analyze the factors underlying the decision to produce for a particular market and compare the three groups of farmers based on data from the 2007 agricultural census. A generalized ordered logit model was used to analyze different methods of production, and non-parametric methods were used to compare the groups. Results show that some farmers change categories in sequence; farmers that produce for the domestic market can later produce for...

A 2-year-old East Friesian sheep imported from Australia exhibited severe anemia after contagious pustular dermatitis in Hokkaido, Japan. Hemoplasma infection was confirmed in blood smears. Both Mycoplasma ovis and ‘Candidatus Mycoplasma haemovis’ were detected by PCR and sequence analyses. In the epidemiological analysis, dual pathogens were detected in 6 of 12 (50.0%) sheep imported from Australia with the infected ewe at the same time, 1 of 5 (20.0%) sheep introduced from a domestic farm in Hokkaido, and in 1 of 16 (6.3%) sheep from an epidemiologically unrelated ranch. It is the first clinical case of sheep to confirm coinfection of these pathogens in Japan.

A comparative analysis of ALOS PALSAR L-band and RADARSAT-2 C-band data for land-cover classification in a tropical moist region. Repositório Alice
LI, G.; LU, D.; DUTRA, L.; BATISTELLA, M..
This paper explores the use of ALOS (Advanced Land Observing Satellite) PALSARL-band (Phased Array type L-band Synthetic Aperture Radar) and RADARSAT-2 C-band data for land-cover classification in a tropical moist region. Transformed divergence was used to identify potential textural images which were calculated with the gray-level co-occurrence matrix method. The standard deviation of selected textural images and correlation coefficients between them were then used to determine the best combination of texture images for land-cover classification. Classification results based on different scenarios with maximum likelihood classifier were compared. Based on the identified best scenarios, different classification algorithms ? maximum likelihood classifier,...

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products AgEcon
Hudson, Darren; Gallardo, Rosa Karina; Hanson, Terrill R..
In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

A Comparison of Consumer Willingness to Pay for Four Types of Sweeteners AgEcon
Deng, Xueting; Saghaian, Sayed H.; Woods, Timothy A..
As the U.S. consumption of sweeteners has increased, analysis of the demand for sweeteners has become more important. In this paper, consumer willingness-to-pay (WTP) for selected four types of sweeteners is evaluated. The four types of sweeteners are Kentucky grown pure maple syrup, artificially maple flavored syrup, sorghum syrup and molasses. Results suggest that consumers who are at high household income level (above $80,000) and with a smaller household size are likely to pay more for Kentucky grown maple syrup. Results show that there is no statistic difference for the annual household consumption among the four types of sweeteners.
