Aggregate and Farm-level Productivity Growth in Tobacco: Before and After the Quota Buyout AgEcon
Kirwan, Barrett E.; White, T. Kirk; Uchida, Shinsuke.
We examine the distortionary effects of agricultural policy on farm productivity by examining the response of U.S. tobacco farmers' productivity to the quota buyout of 2004. We isolate the impact of distortionary policy, i.e., the tobacco quota, by decomposing aggregate productivity growth into the contribution of farm-level productivity growth and the contribution of reallocation of resources among tobacco growers. Reallocation of resources includes entry into and exit from tobacco farming, as well as growth or decline of the resources allocated to existing tobacco farms. We find that aggregate productivity of Kentucky tobacco farms grew 37% between 2002 and 2007. Reallocation of resources among continuing tobacco farms contributed 22 percentage points...

Biology of Corecoris dentiventris Berg, 1884 (Hemiptera, Coreidae) in tobacco culture (Nicotiana tabacum) BJB
CALDAS,B.-H. C.; REDAELLI,L. R.; DIEFENBACH,L. M. G..
Corecoris dentiventris Berg, 1884 (HEM., Coreidae) represents a pest in the tobacco culture in Southern Brazil. Nymphs and adults cause the wilting and twisting of the tobacco leaves due to their sucking habit. There are very few works about this species and these are restricted to concise description of the adult morphology, records of host plants and enumeration of injuries. The present investigation aims to study the life cycle of this bug. The experiment was carried out in a tobacco culture (Virginia type, var. K 326) implanted in the experimental area of the Departamento de Fitossanidade of the Universidade Federal do Rio Grande do Sul, in Porto Alegre, RS. The life cycle was studied in field conditions, in nylon cages, from egg clusters oviposited by...

Biomass smoke COPD has less tomographic abnormalities but worse hypoxemia compared with tobacco COPD BJMBR
Meneghini,A.C.; Koenigkam-Santos,M.; Pereira,M.C.; Tonidandel,P.R.; Terra-Filho,J.; Cunha,F.Q.; Menezes,M.B. de; Vianna,E.O..
Special attention has emerged towards biomass smoke-induced chronic obstructive pulmonary disease (COPD), providing new knowledge for prevention and therapeutic approach of non-smoker COPD patients. However, the understanding of biomass smoke COPD is still limited and somewhat controversial. The aim of the present study was to compare COPD exclusively caused by tobacco smoking with COPD exclusively caused by environmental or occupational exposures. For this cross-sectional study, COPD patients were recruited from outpatient clinics and formed two groups: non-smoker COPD group (n=16) with exposure to biomass smoke who did not smoke cigarette and tobacco smoker COPD group (n=15) with people who did not report biomass smoke exposure. Subjects underwent...

CHANGING TOBACCO MARKETS: EFFECTS ON BURLEY TOBACCO FARMS AgEcon
Tiller, Kelly; Ray, Daryll E.; Slinsky, Stephen P..
Three representative Tennessee tobacco farms are used to estimate farm-level impacts of (1) program continuation with further quota cuts, and (2) program elimination in 2000. Results indicate that program elimination has more potential to reduce farm income and that larger and more diversified farms are less affected in both scenarios.

Cloning and sequence analysis of tomato cpDNA fragments: towards developing homologous chloroplast transformation vectors Braz. J. Plant Physiol.
Berger,Irving Joseph; Carraro,Dirce Maria; Bock,Ralph; Azevedo,Ricardo Antunes; Carrer,Helaine.
With the view of developing chloroplast transformation vectors based on homologous targeting regions for tomato (Lycopersicon esculentum L.), plastid DNA fragments of tomato cv. IAC-Santa Clara were cloned and analyzed. Isolation and cloning of PstI/SalI chloroplast fragments into the pBlueScript vectors yielded the plasmids pIJB1 and pIJB2 with cpDNA fragments of 8.6 kb and 6.4 kb, respectively. DNA sequencing and computer analyses revealed that the tomato sequences cloned display from 93 to 100 % of identity to the respective fragments in tobacco, which is more pronounced in coding regions. The intergenic spacers are somewhat less conserved suggesting that evolutionary divergences occurred mainly in these putative non-coding regions. The most remarkable...

Complementing firewood with alternative energy sources in Rio Pardo Watershed, Brazil Ciência Rural
Dessbesell,Luana; Farias,Jorge Antonio de; Roesch,Fábio.
ABSTRACT: Wood is the primary energy source for grains and Tobacco drying in the Rio Pardo Watershed (RPW). The amount of firewood produced in the RPW is not enough to supply the demand. Recently, an automatized supply system was introduced in the region enabling the use of sawdust and pellets. In this context, this study aims to compare firewood, sawdust and pellets as energy sources for Tobacco curing in air-forced curing systems. Energetic density was used to estimate the biomass consumption in Tobacco curing. The consumption of biomass is lower for pellet, followed by firewood and sawdust. Pellets and sawdust could complement firewood in the region; however, research is necessary to ascertain the economic feasibility.

Effect of smoking habits on sleep BJMBR
Conway,S.G.; Roizenblatt,S.S.; Palombini,L.; Castro,L.S.; Bittencourt,L.R.A.; Silva,R.S.; Tufik,S..
To evaluate the effect of smoking habits on sleep, data from 1492 adults referred to the Sleep Institute were accessed and divided into 3 categories of smoking status: current, former and non-smokers. Categories of pack-years (<15 and ≥15) defined smoking severity. The association of smoking status and smoking severity with sleep was analyzed for sleep parameters, especially apnea and hypopnea index (AHI) ≥5, more than 5% of total sleep time (TST) spent with oxyhemoglobin saturation (SaO2) <90%, and arousal index. The arousal index was higher among current (21 ± 17) and former smokers (20 ± 17) than non-smokers (17 ± 15; P < 0.04). Former smokers had a higher percent of TST at SaO2 <90% than non-smokers (9 ± 18 vs 6 ± 13; P < 0.04). Former...

HOPES AND FEARS: THE NEW WORLD TRADE NEGOTIATIONS AND SOUTHERN AGRICULTURE AgEcon
Marchant, Mary A..
Understanding the impacts of the Uruguay Round (UR) Agreement on southern commodities serves as a starting point to assess the potential impacts of the next global trade negotiations in terms of hope (expanding export markets) and fear (new competition). Key issues examined include whether or not the UR Agreement resulted in new markets or new competition for key southern commodities-cotton, poultry, tobacco, and rice. For new markets, export data were analyzed to determine if exports increased since the passage of the UR Agreement in 1994. Also, countries that are leading world importers of these southern commodities were identified and data analyzed to determine whether the U.S. is exporting to these top markets. Alternatively, to assess whether the...

Market Access by Smallholder Farmers in Malawi: Implications for Technology Adoption, Agricultural Productivity, and Crop Income AgEcon
Zeller, Manfred; Diagne, Aliou; Mataya, Charles.
In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, agricultural policy promoted hybrid maize and, more recently, tobacco to increase smallholder income. This paper presents an analysis of what determines the adoption of these two crops and what kind of income effects follow from adoption. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income.

MEASURING THE QUALITY OF IMPORTED TOBACCO AgEcon
Davis, George C.; Hewitt, William J..
Domestic tobacco producers have faced increasing competition from imported tobacco since the late 1970s. Much of the debate has centered on the unknown quality of imported tobacco. This study provides a discussion and clarification of the concept of quality, and demonstrates a method of measuring the average quality of imported tobacco. The results show that since 1977, imported tobacco has been steadily decreasing in average quality and moving toward lower quality producing countries and types of tobacco. The reasons for this decline are discussed along with the policy implications.
