Mode Of Production

This article attempts to provide a breakthrough which I call mode of production theory. This theory will be employed to analyze the contemporary phenomenon of radical Islamism. The mode of production theory is meant to bridge the two clashing theoretical paradigms in social sciences and humanities, i.e., Weberian and Marxian. Despite its bridging nature, the paper argues that the two cannot be merged within one single thread. This is because each paradigm has its own epistemological basis which is irreconcilable to one another. Mostly adapted from Marx’s theory, the current theory of the mode of production covers five interrelated aspects, namely social, political, economic, cultural, and symbolic structures. If Marx’s mode of production theory heavily relies on a material and economic basis, the theory used in this paper accommodates cultural and symbolic structures that are Weberian in nature. Although the two paradigms can operate together, the strength of structure (Marxian) overpowers the strength of culture (Weberian). This paper further argues that such cultural-based aspects as ideology, norms, and values play as mobilizing factors under a big schematic dominant structure in the rise and development of the radical Islamist groups.

Specific Speed

The ultra-low specific speed centrifugal pump has been widely applied in aerospace engineering, metallurgy, and other industrial fields. However, its hydraulic design lacks specialized theory and method. Moreover, the impeller and volute are designed separately without considering their coupling effect. Therefore, the optimal design is proposed in this study based on the local entropy production theory. Four geometrical parameters are selected to establish orthogonal design schemes including blade outlet setting angle, wrapping angle volute inlet width, and throat area. Subsequently, a 3D steady flow with Reynolds stress turbulent model and energy equation model is numerically conducted and the entropy production is calculated by a user-defined function code. The range analysis is made to identify the optimal scheme indicating that the combination of local entropy production and orthogonal design is feasible on pump optimization. The optimal pump is visibly improved with an increase of 1.08% in efficiency. Entropy production is decreased by 16.75% and 6.03% in impeller and volute, respectively. High energy loss areas are captured and explained in terms of helical vortex and wall friction, and the turbulent and wall entropy production are respectively reduced by 3.82% and 14.34% for the total pump.

AbstractWe make use of a large sample of transaction-level institutional trading data to test an extended version of Brennan and Hughes’ (1991) information production theory of stock splits. We compare brokerage commissions paid by institutional investors before and after a split, assess the private information held by them, and relate the informativeness of their trading to brokerage commissions paid. We show that institutions make abnormal profits net of brokerage commissions by trading in splitting stocks. We also show that the information asymmetry faced by firms goes down after stock splits. Overall, our empirical results support the information production theory.

Optimum commission rate of the hotel paid to the chartered travel operator

This study aims to derive the optimal commission rate paid by the hoteliers to the chartered travel operators in order to maximize the profit of the hoteliers. This study uses the theoretical maximization model of the manufacturer's production theory of economics. The optimum commission rate of the hoteliers paid to the chartered travel operators is derived and has been proved its existence, and its value is never larger than 1/2. The maximization profit of the hotels can be obtained. This paper is novel in two respects. First, this paper explores that the commission rate is a decision variable determined by the hoteliers, not a constant as the previous studies assumed. Second, the sales channel issues of the hotel other than OTAs such as chartered travel industry have hardly been discussed. This paper explores the issue of the optimum commission rate paid by the hotels to the chartered travel operators.

David Ricardo

Smith is considered the father of the labour theory of value developed by David Ricardo and Karl Marx and simultaneously of the cost-of-production theory of value developed by John Stuart Mill and Alfred Marshall. This polysemy is partly because Smith is developping the terminology to refer to value and measure of value, and often uses it with much imprecision. That has led to different interpretations about his position on these issues, most of them derived from an error of interpretation of Ricardo and Marx. This paper reviews the concepts developed by Smith to formulate his theory of value (value, real price and exchangeable value). Our interpretation of his texts on value does not coincide with what has traditionally been done. According to our interpretation, it would not be correct the criticism made by Ricardo and Marx on Smith’s position about the role of labour as measure of value. For these authors, Smith is not consistent in proposing that the value of a commodity is defined or measured as the amount of labour necessary to produce it and simultaneously as the amount of labour that can be purchased by this commodity. We try to show that for Smith the labour has a double role –as source and measure of value–, and that to it is due the confusion that generates his use of some terms: Smith proposes labour as a measure of value because he conceives it as a source of value. With this interpretation it becomes clear, paradoxically, that Smith holds a labour theory of value that substantially corresponds to the one later developed by Ricardo and Marx.
