Abstract The two most basic non-metaphysical materials used by economists to erect their theoretical structures are prices and quantifies. Two visions of reality are contrasted: (a) that in which historical price determination is explained without reference to demand (Sraffa), and (b) that in which the determination of quantities in historical time is explained without explicit reference to supply (Keynes). In the neoclassical vision of reality, prices and quantities are simultaneously determined by both demand and supply in logical time. It is then argued that the "post-keynesian" appellation is misleading. What is needed is a truly post-classical approach based on the works of Keynes, Sraffa and Marx.

And Performance

Determination of fish landing price is important, as the same contributes to the structure, conduct and performance of the fish market in Lake Victoria. Determination of relevant landing price is a gap to console between fishermen, agents (middlemen), processors and the government. The main objective of this study was therefore to examine fish price determination. Specifically, to examine the methods for fish price determination and analyse factors that affect fish landing price in Lake Victoria, a cross-sectional design was employed, and 300 respondents were randomly selected from two district councils, namely, Sengerema and Buchosa. Both qualitative and quantitative data were analysed using descriptive statistics and inferential analysis. Findings show that landing price is determined through formal negotiation with processors, consultation with other traders, informal negotiation with buyers and Beach Management Unit (BMU). The study concluded that these are the common methods used to determine landing prices. Also, distance from fishing to onshore landing centres, market information channels, age and experiences of the fishermen are the factors significantly found affecting landing price. It is recommended that the mechanism for setting up fishery price, fish market structure, fishery information and the formation of fishery regulatory body needs fishery policy and sector reforms that mark the determination of fish landing price.

Philosophical Aspect

The author of the article turns attention to the phenomenon of human life, recognizing it as the value which is hard and complicated to define. The price of a human life comprises philosophical, political, sociological and legal issues. From the legal and philosophical aspect the price of a human life is practically impossible to determine, since it is worth the highest price. Determination of the price of human life means admitting that a human is the measure of value in a certain community under appropriate socially economic conditions. Different approaches and methodologies are applied in determination of a materialized price of a human life, therefore the rating of the price is varied. In determining the price of a human life, the legal aspect is important, since it deals with the fixation of the amount of compensations in cases of an individual's loss of life and calculations of the insurance costs.

Abstract Previous studies have shown that the Ancient Egyptians used malted wheat and barley as the main ingredients in beer brewing, but the chemical determination of the exact recipe is still lacking. To investigate the constituents of ancient beer, we conducted a detailed IR and GC-MS based metabolite analyses targeting volatile and non-volatile metabolites on the residues recovered from the interior of vats in what is currently the world’s oldest (c. 3600 BCE) installation for large-scale beer production located at the major pre-pharaonic political center at Hierakonpolis, Egypt. In addition to distinguishing the chemical signatures of various flavoring agents, such as dates, a significant result of our analysis is the finding, for the first time, of phosphoric acid in high level probably used as a preservative much like in modern beverages. This suggests that the early brewers had acquired the knowledge needed to efficiently produce and preserve large quantities of beer. This study provides the most detailed chemical profile of an ancient beer using modern spectrometric techniques and providing evidence for the likely starting materials used in beer brewing.
