Changes in the foreign trade structure of the Russian Far East under the process of transition toward a market economy

Under the process of transition toward a market economy, the economic connections of the Russian Far East (RFE) with external regions changed from a division of labor among the regions of the USSR (Russia) to an international division of labor. This happened due to factors including the liberalization of the trade system away from a state monopoly, the presence of rich natural resources and of developed industries related to these resources, the advantage of geographically proximity to Asia-Pacific countries, and the political and economic division of the once unified national economic space during the process of transition. The economic connections of RFE with external economies changed radically under the transition toward the market economy. First, the value of foreign trade increased dramatically and the importance of foreign trade for the RFE economy increased enormously. Second, however, different territories of RFE traveled along different trajectories, due to factors involving their industrial structure and geographical conditions. Third, in recent years connections with China, in the areas of both exports and imports, have grown. Fourth, the share within exports of "fuel, mineral resources and metal" increased radically from the end of the 1990s, and the share of "machine, facilities and transportation means" increased from 2002 year within imports. Under this situation, especially since 2002, there has been a major change in the structure of foreign trade.

The Changing Nature of Employment and the Reform of Labor and Social Security Legislation in Post-Apartheid South Africa

This paper tries to understand the current status of South African labor market, which is changing in contradictory directions, i.e. a strengthening of the rights and protection of workers at the same time as the flexibilization of employment, in the context of the characteristics of labor and social security legislation in South Africa, as well as the nature of labor and social security reforms after democratization. We put emphasis on the corporatist nature of labor policy-making as the factor influencing the course of reforms; it is argued that the apparently contradictive changes can be explained consistently by the corporatist labor policy-making process which has been practiced notwithstanding the problem of representativeness.

Backward-bending of labor supply function and free riders

It seems like that backward- bending of labor supply function can be observed in Central Asian Countries such as Uzbekistan and Kazakhstan. People’s basic needs of life are satisfied and they do not increase labor supplies even if wage increases. It is possible to find some cases in which slowdowns increase, when a manager in a firm enforces penalties for workers have slowdowns. This phenomenon occurs because a worker prefers the position of equilibrium on the labor supply function always in the upper direction. This article explains the increase of free-riders by penalties and how to avoid them.

Authoritarianism and labor market : preference of labor policies in the Arab Gulf countries

Migrant and labor issues are a primary concern in the Arab Gulf countries. With focus on the economic and political conditions that influence actors' decisions when framing labor policies, this study analyzes how preferences of such policies are formed and explains why the governments of the Arab Gulf countries attempt to implement less economical policies. The findings suggest that governments avoid concessions for enterprises required to implement more economical policies and chose uneconomical ones to maintain authoritarian regimes.

enod40 induces dedifferentiation and division of root cortical cells in legumes

Under nitrogen-limiting conditions Rhizobium meliloti can establish symbiosis with Medicago plants to form nitrogen-fixing root nodules. Nodule organogenesis starts with the dedifferentiation and division of root cortical cells. In these cells the early nodulin gene enod40, which encodes an unusually small peptide (12 or 13 amino acids), is induced from the beginning of this process. Herein we show that enod40 expression evokes root nodule initiation. (i) Nitrogen-deprived transgenic Medicago truncatula plants overexpressing enod40 exhibit extensive cortical cell division in their roots in the absence of Rhizobium. (ii) Bombardment of Medicago roots with an enod40-expressing DNA cassette induces dedifferentiation and division of cortical cells and the expression of another early nodulin gene, Msenod12A. Moreover, transient expression of either the enod40 region spanning the oligopeptide sequence or only the downstream region without this sequence induces these responses. Our results suggest that the cell-specific growth response elicited by enod40 is involved in the initiation of root nodule organogenesis.

On the Role of Myosin-II in Cytokinesis: Division of Dictyostelium Cells under Adhesive and Nonadhesive Conditions

We have investigated the role of myosin in cytokinesis in Dictyostelium cells by examining cells under both adhesive and nonadhesive conditions. On an adhesive surface, both wild-type and myosin-null cells undergo the normal processes of mitotic rounding, cell elongation, polar ruffling, furrow ingression, and separation of daughter cells. When cells are denied adhesion through culturing in suspension or on a hydrophobic surface, wild-type cells undergo these same processes. However, cells lacking myosin round up and polar ruffle, but fail to elongate, furrow, or divide. These differences show that cell division can be driven by two mechanisms that we term Cytokinesis A, which requires myosin, and Cytokinesis B, which is cell adhesion dependent. We have used these approaches to examine cells expressing a myosin whose two light chain-binding sites were deleted (ΔBLCBS-myosin). Although this myosin is a slower motor than wild-type myosin and has constitutively high activity due to the abolition of regulation by light-chain phosphorylation, cells expressing ΔBLCBS-myosin were previously shown to divide in suspension (Uyeda et al., 1996). However, we suspected their behavior during cytokinesis to be different from wild-type cells given the large alteration in their myosin. Surprisingly, ΔBLCBS-myosin undergoes relatively normal spatial and temporal changes in localization during mitosis. Furthermore, the rate of furrow progression in cells expressing a ΔBLCBS-myosin is similar to that in wild-type cells.

Division of Mitochondria Requires a Novel DNM1-interacting Protein, Net2p

Mitochondria are dynamic organelles that undergo frequent division and fusion, but the molecular mechanisms of these two events are not well understood. Dnm1p, a mitochondria-associated, dynamin-related GTPase was previously shown to mediate mitochondrial fission. Recently, a genome-wide yeast two-hybrid screen identified an uncharacterized protein that interacts with Dnm1p. Cells disrupted in this new gene, which we call NET2, contain a single mitochondrion that consists of a network formed by interconnected tubules, similar to the phenotype of dnm1Δ cells. NET2 encodes a mitochondria-associated protein with a predicted coiled-coil region and six WD-40 repeats. Immunofluorescence microscopy indicates that Net2p is located in distinct, dot-like structures along the mitochondrial surface, many of which colocalize with the Dnm1 protein. Fluorescence and immunoelectron microscopy shows that Dnm1p and Net2p preferentially colocalize at constriction sites along mitochondrial tubules. Our results suggest that Net2p is a new component of the mitochondrial division machinery.

Long-term change in the organization of inventive activity

Relying on a quantitative analysis of the patenting and assignment behavior of inventors, we highlight the evolution of institutions that encouraged trade in technology and a growing division of labor between those who invented new technologies and those who exploited them commercially over the nineteenth and early-twentieth centuries. At the heart of this change in the organization of inventive activity was a set of familiar developments which had significant consequences for the supply and demand of inventions. On the supply side, the growing complexity and capital intensity of technology raised the amount of human and physical capital required for effective invention, making it increasingly desirable for individuals involved in this activity to specialize. On the demand side, the growing competitiveness of product markets induced firms to purchase or otherwise obtain the rights to technologies developed by others. These increasing incentives to differentiate the task of invention from that of commercializing new technologies depended for their realization upon the development of markets and other types of organizational supports for trade in technology. The evidence suggests that the necessary institutions evolved first in those regions of the country where early patenting activity had already been concentrated. A self-reinforcing process whereby high rates of inventive activity encouraged the evolution of a market for technology, which in turn encouraged greater specialization and productivity at invention as individuals found it increasingly feasible to sell and license their discoveries, appears to have been operating. This market trade in technological information was an important contributor to the achievement of a high level of specialization at invention well before the rise of large-scale research laboratories in the twentieth century.

Mechanisms and streams for processing of “what” and “where” in auditory cortex

The functional specialization and hierarchical organization of multiple areas in rhesus monkey auditory cortex were examined with various types of complex sounds. Neurons in the lateral belt areas of the superior temporal gyrus were tuned to the best center frequency and bandwidth of band-passed noise bursts. They were also selective for the rate and direction of linear frequency modulated sweeps. Many neurons showed a preference for a limited number of species-specific vocalizations (“monkey calls”). These response selectivities can be explained by nonlinear spectral and temporal integration mechanisms. In a separate series of experiments, monkey calls were presented at different spatial locations, and the tuning of lateral belt neurons to monkey calls and spatial location was determined. Of the three belt areas the anterolateral area shows the highest degree of specificity for monkey calls, whereas neurons in the caudolateral area display the greatest spatial selectivity. We conclude that the cortical auditory system of primates is divided into at least two processing streams, a spatial stream that originates in the caudal part of the superior temporal gyrus and projects to the parietal cortex, and a pattern or object stream originating in the more anterior portions of the lateral belt. A similar division of labor can be seen in human auditory cortex by using functional neuroimaging.
