Liberalization of Trade in Services and Productivity Growth in Korea

This paper investigates the changes in productivity growth rates of Korean service and manufacturing subsectors in relation to the liberalization of trade in services. Since Korea underwent accelerated liberalization of the service sector in the 1990s, we try to examine whether the service subsectors which were liberalized, and the manufacturing subsectors which use liberalized services as inputs, experienced productivity gains in this period.liberalization, trade services, Korea

The principle of fairness : theory, defence, and application

Theories of social justice propose various principles for the just regulation of social institutions and practices. However, why should individuals comply with the rules of just social institutions? To answer this question, a theory of obligation is required. This thesis examines and defends the principle of fairness as a theory of individual obligation. It begins by reviewing the debates within political philosophy over the principle since its initial formulation by H. L. A. Hart. Thereafter, the defence of the principle of fairness proceeds in three stages. First, the thesis explores the moral foundations of the principle. It is argued that the concepts of right, equality, and fairness as reciprocity work as the moral foundations provided that fairness as reciprocity has priority over right and equality. On the basis of this reciprocity-based foundation, a revised principle of fairness is stated, which specifies the conditions for the justification of an obligation to follow institutional rules. Second, the thesis rebuts main objections levelled against the principle: the consent argument, the limiting argument, and the utility argument. Finally, the principle of fairness is defended as a principle that has appealing normative implications for one of the most important challenges we face in recent times, global climate change. With theoretical elaboration, defence against main objections, and practical application, this thesis presents a comprehensive development of the principle of fairness as a plausible theory of obligation

A relative of Hadwiger's conjecture

Hadwiger's conjecture asserts that if a simple graph $G$ has no $K_{t+1}$ minor, then its vertex set $V(G)$ can be partitioned into $t$ stable sets. This is still open, but we prove under the same hypotheses that $V(G)$ can be partitioned into $t$ sets $X_1,\ldots, X_t$, such that for $1\le i\le t$, the subgraph induced on $X_i$ has maximum degree at most a function of $t$. This is sharp, in that the conclusion becomes false if we ask for a partition into $t-1$ sets with the same property.Comment: 6 page

Dietary Cholesterol Affects Lipid Metabolism in Rabbits

Effects of dietary cholesterol (0 (control), 1, 2, 4 or 8 g cholesterol/kg diet for 12 wks) on lipid contents and fatty acid compositions in red blood cell (RBC) membranes and plasma of rabbits and pathological changes and lipid oxidation in their livers were determined. Contents of total lipid and unsaturated fatty acids in RBC membrane and plasma of rabbits fed ≥4 g and ≥2 g dosages, respectively, were significantly higher (P \u3c 0.05) than those of the control, and their increases were dosage-dependent. Accumulations of neutral lipids in centrolobular regions of livers in rabbits fed ≥ 2 g were dosage-dependent. Lipid oxidation in liver of rabbits fed 8 g was \u3e2 times higher (P \u3c 0.05) than those fed lower dosages. The results indicated that dietary cholesterol can modify lipid metabolisms of rabbits, including biosynthesis and transportation of lipids and fatty acids and incorporation of fatty acid into RBC membranes
