The Impact of Coordination of Production and Marketing Strategies on Price Behavior: Evidence from the Idaho Potato Industry

High potato price volatility, decreasing demand for fresh potatoes and prices below the cost of production led to a decision of a number of Idaho potato growers to organize the United Fresh Potato Growers of Idaho, a marketing cooperative. The programs and strategies of the cooperative target both the production and marketing of fresh potatoes in Idaho. To evaluate the effectiveness of the programs implemented by the cooperative, we examine the level and volatility of fresh potato prices during two periods: before the cooperative was organized and when the cooperative is in the market. We find empirical evidence suggesting that fresh potato prices were higher and less volatile during the period when the cooperative was in the market.agricultural markets, cooperative, price volatility, potato industry, Agricultural and Food Policy, Crop Production/Industries, Demand and Price Analysis, Marketing, Q10, Q11, Q13,

The import substituted poultry industry; evidence from Ghana

Rapid growth in Ghana’s poultry imports revealed the weaknesses of the domestic industry in competing with imported products. Establishment of an intensive poultry system as a benchmark for examining the performance poultry production and marketing in addition to interviews with poultry stakeholders revealed the constraints in the poultry industry in Ghana. Results emphasized that Feed Conversion Rate is a major factor in reducing production cost and improving the broilers growth efficiency. The BNARI feed conversion rate for the broiler is 1.56 Kilogram of feed needed to produce 1 kg live weight compared to 2.12 kg of feed to produce 1 kg live weight by other poultry farmers engaged in the study. Feed costs represent more than 70% of the total cost of broilers production, and feed utilization efficiency, are critical for the growth rate of broilers. A major constraint is the lack of protection on the infant poultry industry by the Ghana government leading to unfair competition with cheap imported poultry products, which is 30-40 percent cheaper and undermines the growth of the local industry. Other constraints are high feed cost, high chick mortality as a result electricity power outage for brooding, feed and water contamination and consumer preference for imported poultry meat. There is still 74% demand market share to be fulfilled. The Ghana poultry industry is insecure because poultry farms are collapsing faster than new farms are being established or old farms are being expanded. There is a need for serious intervention by the government through policies and enforcements to reverse this trend.Kwamina Ewur. Banson, Gobinath Muthusamy, Ebenezer Kond

Effects of wastewater treatment plant effluent inputs on planktonic metabolic rates and microbial community composition in the Baltic Sea

The Baltic Sea is the world's largest area suffering from eutrophication-driven hypoxia. Low oxygen levels are threatening its biodiversity and ecosystem functioning. The main causes for eutrophication-driven hypoxia are high nutrient loadings and global warming. Wastewater treatment plants (WWTP) contribute to eutrophication as they are important sources of nitrogen to coastal areas. Here, we evaluated the effects of wastewater treatment plant effluent inputs on Baltic Sea planktonic communities in four experiments. We tested for effects of effluent inputs on chlorophyll <i>a</i> content, bacterial community composition, and metabolic rates: gross primary production (GPP), net community production (NCP), community respiration (CR) and bacterial production (BP). Nitrogen-rich dissolved organic matter (DOM) inputs from effluents increased bacterial production and decreased primary production and community respiration. Nutrient amendments and seasonally variable environmental conditions lead to lower alpha-diversity and shifts in bacterial community composition (e.g. increased abundance of a few cyanobacterial populations in the summer experiment), concomitant with changes in metabolic rates. An increase in BP and decrease in CR could be caused by high lability of the DOM that can support secondary bacterial production, without an increase in respiration. Increases in bacterial production and simultaneous decreases of primary production lead to more carbon being consumed in the microbial loop, and may shift the ecosystem towards heterotrophy

Hygromycin B, carboxin and nourseothricin susceptibility of polyunsaturated fatty acid producing Mortierella and Umbelopsis strains

Mortierella and Umbelopsis species are particularly active in polyunsaturated fatty acid (PUFA) synthesis as they are able to produce many ω-3 and ω-6 PUFAs. Genetic manipulation of the lipid production to generate PUFA overproducing strains and strains with altered PUFA profile requires well-established transformation systems and reliable selectable markers. Therefore, we screened different antifungal agents, which can be used for selection in further transformation experiments. Hygromycin B, carboxin, pyrithiamine and nourseothricin susceptibility of several Mortierella and Umbelopsis isolates was investigated using a broth microdilution method. Pyrithiamine was totally ineffective against all isolates while the other three antifungal agents were active against Mortierella and Umbelopsis strains. Several Mortierella isolates represented high sensitivity to hygromycin B whilst nourseothricin was rather active against Umbelopsis species. Carboxin inhibited the hyphal growth and the spore germination of all isolates completely in low concentrations

Distribution of finfish resources along southeast coast of India in relation to certain environmental parameters

This paper embodies the distribution pattern of major finfish resources along the southeast coast of India as observed during the cruises operated by FORV Sagar Sampada. A total of 16 cruises (1985-90) operated along latitude 7° 15'- 15°00' N and longitude 75°50'- 82°3r E hauled a total catch 37.5 tonnes with a catch rate of 537 kg/hr. The catch was constituted mainly by threadfin breams (43%), perches (14%), barracudas (9.72%), carangids (8.56%) and elasmobranchs (4.81%). Seasonally higher catch rates were obtained during July- September period. Depth range of 60 - 80 m had denser population of finfish resources. Water temperature and salinity appeared to influence the distribution of major finfishes more than dissolved oxygen. Groups such as threadfin breams were found preferring cooler waters of Wadge Bank area, while barracudas appear to occupy warmer waters of Gulf of Mannar

A five-year retrospective review of snakebite patients admitted to a tertiary university hospital in Malaysia

BACKGROUND Although the majority of the snakebite cases in Malaysia are due to non-venomous snakes, venomous bites cause significant morbidity and mortality if treatment measures, especially ant-venom therapy, are delayed. METHODS To determine the demographic characteristics, we conducted a retrospective study on all snakebite patients admitted to the Emergency Department of Hospital Universiti Sains Malaysia (HUSM) from January 2006 to December 2010. RESULTS In the majority of the 260 cases that we found (138 cases or 52.9%), the snake species was unidentified. The most common venomous snakebites among the identified species were caused by cobras (52 cases or 20%). Cobra bites are significantly more likely to result in severe envenomation compared to non-cobra bites. Post hoc analysis also showed that cobra bite patients are significantly less likely to have complete recovery than non-cobra bite patients (48 cases, 75.0% vs. 53 cases, 94.6%; p = 0.003) and more likely to result in local gangrene (11 cases, 17.2% vs. 3 cases, 5.4%; p = 0.044). CONCLUSION Cobra bites are significantly more likely to result in severe envenomation needing anti-venom administration and more likely to result in local gangrene, and the patients are significantly less likely to have complete recovery than those with non-cobra bites

Exploring and Expanding the Fatty-Acid-Binding Protein Superfamily in Fasciola Species

The liver flukes Fasciola hepatica and F. gigantica infect livestock worldwide and threaten food security with climate change and problematic control measures spreading disease. Fascioliasis is also a food borne disease with up to 17 million humans infected. In the absence of vaccines, treatment depends on Triclabendazole (TCBZ) and over-use has led to widespread resistance, compromising future TCBZ control. Reductionist biology from many laboratories has predicted new therapeutic targets. To this end, the fatty acid binding protein (FABP) superfamily have proposed multi-functional roles, including functions intersecting vaccine and drug therapy, such as immune modulation and anthelmintic sequestration. Research is hindered by a lack of understanding of the full FABP superfamily complement. Although discovery studies predicted FABPs as promising vaccine candidates, it is unclear if uncharacterised FABPs are more relevant for vaccine formulations. We have coupled genome, transcriptome and EST data mining with proteomics and phylogenetics, to reveal a liver fluke FABP superfamily of 7 clades: previously identified clades I-III and newly identified clades IV-VII. All new clade FABPs were analysed using bioinformatics and cloned from both liver flukes. The extended FABP dataset will provide new study tools to research the role of FABPs in parasite biology and as therapy targets

Improving the fluorescent probe acridonylalanine through a combination of theory and experiment

Acridonylalanine (Acd) is a useful fluorophore for studying proteins by fluorescence spectroscopy, but it can potentially be improved by being made longer wavelength or brighter. Here, we report the synthesis of Acd core derivatives and their photophysical characterization. We also performed ab initio calculations of the absorption and emission spectra of Acd derivatives, which agree well with experimental measurements. The amino acid aminoacridonylalanine (Aad) was synthesized in forms appropriate for genetic incorporation and peptide synthesis. We show that Aad is a superior Förster resonance energy transfer acceptor to Acd in a peptide cleavage assay and that Aad can be activated by an aminoacyl tRNA synthetase for genetic incorporation. Together, these results show that we can use computation to design enhanced Acd derivatives, which can be used in peptides and proteins

Phenotype and genotype of concurrent keratoconus and Fuchs endothelial corneal dystrophy

PURPOSE: To characterise the phenotype and genotype of concurrent keratoconus and Fuchs endothelial corneal dystrophy (KC + FECD). METHODS: We recruited 20 patients with concurrent KC + FECD for a retrospective observational case series from the United Kingdom and the Czech Republic. We compared eight parameters of corneal shape (Pentacam, Oculus) with two groups of age-matched controls who had either isolated keratoconus (KC) or isolated FECD. We genotyped probands for an intronic triplet TCF4 repeat expansion (CTG18.1) and the ZEB1 variant c.1920G >T p.(Gln640His). RESULTS: The median age at diagnosis of patients with KC + FECD was 54 (interquartile range 46 to 66) years, with no evidence of KC progression (median follow-up 84 months, range 12 to 120 months). The mean (standard deviation (SD)) of the minimum corneal thickness, 493 (62.7) μm, was greater than eyes with KC, 458 (51.1) μm, but less than eyes with FECD, 590 (55.6) μm. Seven other parameters of corneal shape were more like KC than FECD. Seven (35%) probands with KC + FECD had a TCF4 repeat expansion of ≥50 compared to five controls with isolated FECD. The average of the largest TCF4 expansion in cases with KC + FECD (46 repeats, SD 36 repeats) was similar to the age-matched controls with isolated FECD (36 repeats, SD 28 repeats; p = 0.299). No patient with KC + FECD harboured the ZEB1 variant. CONCLUSIONS: The KC + FECD phenotype is consistent with KC but with superimposed stromal swelling from endothelial disease. The proportion of cases with a TCF4 expansion is similar in concurrent KC + FECD and age-matched controls with isolated FECD
