Trade And Investment

Of the ten fastest growing economies since 1960, eight are in East Asia. As Haggard (2018) aptly demonstrates for Northeast Asia, two explanations account for this exceptional regional performance. On the one hand, neo-liberals committed to an Anglo-American night-watchman state (Krueger 1978; Bhagwati 1978; Edwards 1993; World Bank 1993; Pack and Saggi 2006) attribute performance to macroeconomic stability, provision of public goods, and openness to trade and investment. On the other hand, a heterodox group (Johnson 1982; Amsden 1989; Wade 1990/2004; Chang 2002, 1994; Rodrik 1995; Evans 1995; Lin 2009) focuses on market and coordination failures and the need for states to adopt pragmatic, ‘trial and error’ and selective approaches to high-speed growth. In this latter view, the strong developmental states of Northeast Asia used their embedded autonomy viz the private sector to overcome market and coordination failures to usher in rapid growth and technological catch-up.

SummaryA review is given of developments in the field of aeroelasticity during the past ten years. The effect of steadily increasing Mach number has been two-fold: on the one hand the aerodynamic derivatives have changed, and in some cases brought new problems, and on the other hand the design for higher Mach numbers has led to thinner aerofoils and more slender fuselages for which the required stiffness is more difficult to provide. Both these aspects are discussed, and various methods of attack on the problems are considered. The relative merits of stiffness, damping and massbalance for the prevention of control surface flutter are discussed. A brief mention is made of the recent problems of damage from jet efflux and of the possible aeroelastic effects of kinetic heating.

Two different inlet configurations, including a straight pipe and a bent pipe, were experimentally tested and numerically simulated using a high-speed, low-mass flow centrifugal compressor. The pressure ratios of the compressor with the two inlet configurations were tested and then compared to illustrate the effect of the bent inlet pipe on the compressor. Furthermore, different circumferential positions of the bent inlet pipe relative to the volute are discussed for two purposes. One purpose is to describe the changes in the compressor performance that result from altering the circumferential position of the bent inlet pipe relative to the volute. This change in performance may be the so-called clocking effect, and its mechanism is different from the one in multistage turbomachinery. The other purpose is to investigate the unsteady flow for different matching states of the bent inlet pipe and volute. Thus, the frequency spectrum of unsteady pressure fluctuation was applied to analyze the aerodynamic response. Compared with the straight inlet pipe, the experimental results show that the pressure ratio is modulated and that the choke point is shifted in the bent inlet pipe. Similarly, the pressure ratio can be influenced by altering the circumferential position of the bent inlet pipe relative to the volute, which may have an effect on the unsteady pressure in the rotor section. Therefore, the magnitude of interest spectral frequency is significantly changed by clocking the bent inlet pipe.

And Behavior

A new optically index matched facility has been constructed to investigate tip flows in compressor-like settings. The blades of the one and a half stage compressor have the same geometry, but lower aspect ratio as the inlet guide vanes (IGVs) and the first stage of the low-speed axial compressor (LSAC) facility at NASA Glenn. With transparent blades and casings, the new setup enables unobstructed velocity measurements at any point within the tip region and is designed to facilitate direct measurements of effects of casing treatments on the flow structure. We start with a smooth endwall casing. High speed movies of cavitation and time-resolved PIV measurements have been used to characterize the location, trajectory, and behavior of the tip leakage vortex (TLV) for two flow rates, the lower one representing prestall conditions. Results of both methods show consistent trends. As the flow rate is reduced, TLV rollup occurs further upstream, and its initial orientation becomes more circumferential. At prestall conditions, the TLV is initially aligned slightly upstream of the rotor passage, and subsequently forced downstream. Within the passage, the TLV breaks up into a large number of vortex fragments, which occupy a broad area. Consequently, the cavitation in the TLV core disappears. With decreasing flow rate, this phenomenon becomes more abrupt, occurs further upstream, and the fragments occupy a larger area.

THE BRAND OF THE CELEBRITY AUTHOR IN FINLAND | In the 21st century, the celebrity author has begun to interest researchers not only as a marketing phenomenon, but also as the literary institution’s own phenomenon. In my article, I explore the relationship of the celebrity author to the so-called acclaimed authors of modern times. In Anglo-American research, the celebrity author and the bestselling author are distinguished as separate author types, but in the case of Finnish Jari Tervo, these types combine. For almost 20 years, Jari Tervo has been amongboth the most sold and the most visible celebrity authors in his home country. I examine how the publicity and brand of the Finnish celebrity author are formed. I consider how the brand affects the author’s works on the one hand, and the reception of the works on the other. I point out the limiting effects of the brand, but I also examine how, in combining the high and the low, it affords mobility in the literary fields while it also offers an opportunity to influence society.

Precision Machines

Air Spindles have been used in ultra precision machines for several years due to their advantages such as high speed rotation, low friction, and low vibration, [1]. Air spindles are widely used in these machines for producing precise work pieces. Although, spindles function on a very complicated theoretical basis, [2, 3], their structure is very simple and consists of mainly a rotor and a stator. The rotor/stator could be made of different shapes. A cylindrical shape is the one commonly in use. The spindle designed in this work has a spherical configuration. It has been designed so that it could be moved without application of electric motor and only by a wind turbine system, [4]. The spindle studied in this research uses compressed air for rotor suspension, and has an air turbine for rotating its shaft. A thin air film acts as bearing layer between rotor and stator. In design procedure, operation parameters such as air inlet pressure for turbine, air inlet pressure for bearing, diameter of turbine nuzzles, diameter of bearing nuzzles, clearance between rotor and stator and etc. have been considered, [5]. A prototype spindle has been manufactured using design criteria. The influence of above mentioned parameters have been recognized through experiments.

The effect of the variations of the permeability tensor on the close-to-the-wall behaviour of a turbulent channel flow bounded by porous walls is explored using a set of direct numerical simulations. It is found that the total drag can be either reduced or increased by more than 20 % by adjusting the permeability directional properties. Drag reduction is achieved for the case of materials with permeability in the vertical direction lower than the one in the wall-parallel planes. This configuration limits the wall-normal velocity at the interface while promoting an increase of the tangential slip velocity leading to an almost ‘one-component’ turbulence where the low- and high-speed streak coherence is strongly enhanced. On the other hand, strong drag increase is found when high wall-normal and low wall-parallel permeabilities are prescribed. In this condition, the enhancement of the wall-normal fluctuations due to the reduced wall-blocking effect triggers the onset of structures which are strongly correlated in the spanwise direction, a phenomenon observed by other authors in flows over isotropic porous layers or over ribletted walls with large protrusion heights. The use of anisotropic porous walls for drag reduction is particularly attractive since equal gains can be achieved at different Reynolds numbers by rescaling the magnitude of the permeability only.

This chapter investigates the centrality of the Idea of the Good for Plato's ethics. It is certainly a remarkable fact that just as the Idea of the Good has little presence in the bulk of Anglo-American scholarship on Plato's metaphysics, so it has little presence in accounts of Plato's ethics. The chapter demonstrates that any account of Platonic ethics is seriously deficient if the superordinate Idea of the Good is not the main focus and if the Good is not identified as the absolutely simple first principle of all, the One. There may be a number of reasons for the lack of interest in the Idea of the Good among students of Plato. At least one of these is that it is supposed that Aristotle's critique of the Form of the Good in his Nicomachean Ethics is decisive. The chapter then considers the knowledge of the Forms of the Virtues, and looks at goodness as integrative unity. It also studies the connection between eros and the Good, which is made explicitly by Plotinus in one of the most remarkable passages in his Enneads.

The Cost

This chapter uses the example of the Anglo-American writer Renée Vivien (Pauline Tarn, 1877-1909) to explore what it might mean to claim a lesbian identity at the turn of the nineteenth century. The child of an English father and an American mother who chose France as her primary residence, Vivien embodied a transnational existence. But for those with her class privilege, national boundaries were often flexible, as illustrated by the fact that, while she travelled extensively, Vivien may never have possessed a passport. On the one hand, such an evasion of national belonging may have been liberating, but perhaps at the cost of a sense of shared (sexual communtity) community.

The last global economic crisis has prompted new dynamics in the scope of economic integration: On the one hand, the Transatlantic economy witnessed the formation of the largest economic integration in the human history: the Transatlantic Trade and Investment Partnership (TTIP). On the other hand, Shanghai Cooperation Organization (SCO) recently adopted the economic vision for initiating an economic integration. Since both integration projects were recently launched, this chapter is intended to make a small contribution to the limited scientific resources available to policymakers, academicians, NGOs, etc. In this respect, this chapter first presents a set of political, economic, institutional, and natural conditions suggested in the principal economic integration literature for the success of a regional economic bloc. Second, it aims at evaluating the TTIP and the SCO in the light of these success conditions.
