"Civil Economy and Civilized Economics: Essentials for Sustainable Development"

This essay will consider the relevance of the social sciences - especially economics - to the foundations of sustainable development. Looming environmental crises have served as a prime motivating force for reevaluating fundamental principles. In particular, the concept of sustainability, carrying with it clear requirements for values, goals and ethics, has begun to reshape economics. The broadest conception of sustainability is found if we understand sustainable development to mean Socially And Environmentally Just And Sustainable development - "SAEJAS development". Throughout the paper we will see examples of rules, or norms, that serve to organize human behavior without requiring that everything be rethought all the time. Among these may be found some ethical rules that lay the foundation for responding to the current situation in which humanity finds itself. What notice should the social sciences take of such rules? How would the social sciences - especially economics - have to change in order to be able to pay appropriate attention to ethical norms? "Participatory science," involving citizens as well as specialists, is proposed as an outline for the kind of science that is needed under contemporary circumstances. The approach described under this rubric will be contrasted with the methods and assumptions of mainstream economics. The essay will give some attention to how economic ideas - for better or for worse - affect and shape culture and society. The theory of sustainable development is proposed as offering strong, practical elements of a needed alternative economic paradigm. The conclusion will remind us that theory alone has little effect, and will point to an area where theory and practice can work together to civilize modern economies.civil society, sustainable development, development, SAEJAS, ethics, social capital, environment, new economics,

Consumer Perception of Sorghum Variety Attributes in the Lake Zone Tanzania

Many sorghum varieties have been developed by research institutes in an effort to address food security problems in the semi-arid areas of Tanzania. Although sorghum is better adapted to drier areas than maize, farmer adoption rates for sorghum varieties are always lower than that of maize. In addition, maize based food is more acceptable to urban consumers than sorghum based food. In this study consumer evaluated quality attributes of sorghum ugali based on different varieties in order to determine marketing potential relating to the different improved sorghum varieties. A total of 231 consumers, randomly selected from urban and rural areas participated in a food panel to evaluate ugali prepared from five sorghum varieties (three improved, two local). Conjoint analysis was used to determine consumer perceptions of the variety attributes, while a logistic model was applied to determine preference ranking of different varieties. The results indicated that the color and taste of sorghum ugali were the most important criteria used by consumers to evaluate the quality ugali. The study results indicated that sorghum ugali with white/khaki color and the majority of panel participants preferred neutral or slightly sweet taste. Consumers from rural and urban areas accepted two improved varieties; only consumers from rural areas accepted the remaining variety.Adoption, consumer perception, conjoint analysis, sorghum varieties, Tanzania, Agricultural and Food Policy, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Marketing, Productivity Analysis, Research and Development/Tech Change/Emerging Technologies,

The Level of Farmer Household Food Security and the Influence of the Raskin Policy

The purpose of this study was to (1) suspected the level of farmer household food security in the village of Tanjung Pering, (2) to explore the factors that influence household food security of farmers in the village of Tanjung Pering and (3) explore the influence policy giving rice to the poor (the rice)to the household food security of farmers in the village of Tanjung Pering. The research was conducted in the village of Tanjung Pering, District of North Inderalaya, Ogan Ilir. What research purposely determined in consideration of the community in the village of Tanjung Pering largely livelihood as farmers and rice for many distributed to the village. The results showed that the level of household food security of farmers in the village of Tanjung Pering, District of North Inderalaya, Ogan Ilir, which hold 53.33 percent food, 10 percent of food vulnerable and 36.67 percent less food. Factors that significantly influence the level of household food security of farmers in the village of Tanjung Pering, District of North Inderalaya, Ogan Ilir regency is the price of rice, the number of family members and income

A converging telescopic product : an honors thesis (HONRS 499)

The key result of this paper is a sequence of products which converges to a number of the form mr, where m is an integer such that m > 2 and r is rational. Before the key theorem is presented, the reader is given a brief summary of product sequences and the techniques used to treat them. Then, after the statement and proof of the key theorem, the result is generalized in a corollary to encompass sequences converging to numbers of the form qr, where both q and r are rational.Honors CollegeThesis (B.?.

Nutritional dynamics during the development of xylophagous beetles related to changes in the stoichiometry of 11 elements

The present study examines the adaptive strategy used by wood-boring beetles to compensate for the lack of nutrients in dead wood. The contents of nutritional elements in growing wood-boring beetles (Stictoleptura rubra L. and Chalcophora mariana Dejean) are compared with the elemental composition of decaying dead wood (pine stumps), showing changes during the beetles' ontogenetic (i.e. larval) development. The stoichiometric ratios of C and other nutritional elements (N, P, K, Na, Ca, Mg, Fe, Zn, Mn and Cu) are investigated to identify the most important nutrients for larval development. The degree of nutritional mismatch that is encountered by the beetle larvae changes dramatically over 3-4 years of simultaneous larval growth and wood decay. Excluding C, the relative contents of nutritional elements increase substantially in decaying wood, whereas the opposite tendency is found in larvae, most likely because of carbon deposition in fat. The elements limiting larval development because of their scarcity in dead wood are N, P, K, Na, Mg, Zn and Cu. Fungal activity (i.e. the transport of nutrients from the surrounding environment to decaying stumps) can explain the observed mitigation of the original mismatch, although prolongation of the larval development time is still necessary to compensate for the scarcity of some of the required elements in food

AN ANALYSIS OF HOUSEHOLD FOOD EXPENDITURE SYSTEMS IN TANZANIA

This paper analyzes urban and rural food consumption in Tanzania using the Generalized Translog (GTL) expenditure system. We reject a pooled model in favor of two separate urban and rural models. Results indicate that subsistence consumption has significant effect on food demand in rural areas, but it is less important in urban areas. Hence, ignoring differences between urban and rural regions can lead to incorrect inferences and policy recommendations.Food Consumption/Nutrition/Food Safety,

Fungal transformation of tree stumps into a suitable resource for Xylophagous Beetles via changes in elemental ratios

The elements present in dead pine stumps inhabited by larvae of wood-boring beetles (Stictoleptura rubra, Arhopalus rusticus and Chalcophora mariana) were analyzed over the initial (first 5 years; a chronosequence) stages of wood decay. The quantities of N, P, K, Ca, Mg, Fe, Zn, Mn, Cu and Na (but not S) increased with increases in the content of ergosterol (used as a proxy for the amount of fungal tissue). In fact, the amounts of P, N, K, Fe and Cu presented marked increases. These findings show that fungi stoichiometrically rearrange dead wood by importing externally occurring nutrients to decaying stumps. During the first years of wood decay, the ratios of C to other elements decrease substantially, but differently, for various elements, whereas the N:Fe, N:Cu, N:P and N:K ratios remain relatively stable. Therefore, the stoichiometric mismatch between xylophages and their food is greatly reduced. By changing the nutritional stoichiometry of dead wood, fungi create a nutritional niche for wood-eaters, and these changes enable the development of xylophages

The effect of pre-analytical treatment on the results of stoichiometric measurements in invertebrates

Growing interest in the application of stoichiometric approaches to community ecology has resulted in an increasing number of studies examining invertebrate body composition. Our experiments demonstrate various sources of possible error related to the use of pre-analytical procedures. We examined the effects of different preservatives (ethanol and formaldehyde) used in pitfall traps, time of preservation (2 weeks or 3 days) and drying method (vacuum drying at 50 °C and freeze-drying) on the determination of body composition in invertebrates representing taxa often used in such studies: earthworms and five species of insects (adults or larvae). The contents of C, N, S, P, Fe, Zn, Cu, Mn, Ca, Mg and K in each animal were measured. The use of solvents (ethanol or formaldehyde) in pitfall traps and for preservation significantly affects the body composition and stoichiometry of earthworms, even during short exposure times. Insects (both adults and larvae) were affected only during a 2-week exposure; 3 days of exposure did not significantly change their chemical composition. Vacuum-oven drying of animals at 50 °C does not affect their body composition relative to freeze-drying

Analisis Penanganan Penerimaan Tandan Buah Segar pada PT. Bio Nusantara Teknologi di Kecamatan Pondok Kelapa Kabupaten Bengkulu Tengah

This paper aimed to determine the handling system receiving TBS in PT.Bio Nusantara Teknologi to three supplier of partners supplier, plasma supplier and general supplier and how opportunities for improvement that can be done. This study used decriptive analysis and F test to examined wether there is discrimination in handling treatment and price of TBS among suppliers. The results showed that there are several steps that must be passed TBS suppliers to sell it to the POM: 1) taking a queue number, 2) The calling queue number, 3) Weighing, and 4) Sorting and loading and unloading. There was no difference in the treatment of the company against a third supplier, but the difference is the quality of fruit that would affect the price. The price difference was tested using the Tukey's test or BNJ. From the results of the research sequence starting price of the highest rates of plasma suppliers, partners supplier and then general supplier
