'My Father’s Daughter': Filial Dislocation in Shirley Geok-lin Lim’s Poetry
Drawing on the father figure and the father–daughter dynamic in Shirley Geok-lin Lim’s poetry, this article examines how the motif of filial dislocation underlines ambivalent and complicated emotions and meanings that can be traced back to the poet’s traumatic childhood experience of her father’s violence. This experience, described here as one of acute psychical and emotional rupture and dislocation, has been imprinted onto Lim’s body and consciousness in the form of embodied memories and emotions, and reenacted in writing and poetic articulation where the father figure is concerned. Through the recurring themes of memory, (dis)connection, distance, and dislocation, Lim’s deeply personal, even autobiographical, poems explore the wounded father–daughter relationship; in so doing, they trouble the ideological premise of filial piety as a cultural concept, which upholds the child’s obligation to the parent through the performance of filial care, respect, and obedience. At the same time, Lim’s poems reflect how embodied memories and emotions are relived and refelt in the process of writing as well as the depth of the poet’s emotional response and subjective interiority in the articulation and performance of filial and gender identity. Weaving through and traversing interior and exterior spaces and landscapes of memory and imagination, body and geography, the poems illuminate complex psychological, emotional, and embodied dimensions of Lim’s mediation of her filial and gender identity as a feminist poet, a daughter, and a gendered individual
Modelling Social Infrastructure and Growth
This paper examines the impact of social infrastructure on economic growth by endogenously modelling its provision by a public sector in the context of a multi-sector growth model. Our model shows that not only is social infrastructure positively correlated with output per worker, countries that are more efficient in providing the infrastructure are able to limit the level of diversion while those that are not are unable to do so. Next, we augment the model with human capital which is endogenously determined by the education sector. The extended model indicates a positive link between the education and public sectors such that a shock to one of these sectors affects not only the immediate sector but the other as well. We also show that favourable social infrastructure can have positive long-term growth effects when the Lucas (1988) specification for the accumulation of human capital is adopted. Our results suggest that emphasis should be placed on raising the efficiency level of the public sector and productivity level of the education sector. Finally, the best way of combating diversion is to encourage individuals to adopt a higher degree of aversion to it.Economic Growth, Human Capital, Social Infrastrncture
Coupling Impedances and Heating due to Slots in the KEK B-factory
The longitudinal and transverse coupling impedances produced by the long
slots in the Low Energy Ring of KEK B-factory are calculated. The power
dissipated inside the vacuum chamber due to the fields scattered by the slots
is evaluated using results for the real part of the coupling impedance.
Estimates are made for the power flow through the slots to the pumping chamber.Comment: 14 pages, uuencoded gzipped PS-file (141K
Fourth Order Algorithms for Solving the Multivariable Langevin Equation and the Kramers Equation
We develop a fourth order simulation algorithm for solving the stochastic
Langevin equation. The method consists of identifying solvable operators in the
Fokker-Planck equation, factorizing the evolution operator for small time steps
to fourth order and implementing the factorization process numerically. A key
contribution of this work is to show how certain double commutators in the
factorization process can be simulated in practice. The method is general,
applicable to the multivariable case, and systematic, with known procedures for
doing fourth order factorizations. The fourth order convergence of the
resulting algorithm allowed very large time steps to be used. In simulating the
Brownian dynamics of 121 Yukawa particles in two dimensions, the converged
result of a first order algorithm can be obtained by using time steps 50 times
as large. To further demostrate the versatility of our method, we derive two
new classes of fourth order algorithms for solving the simpler Kramers equation
without requiring the derivative of the force. The convergence of many fourth
order algorithms for solving this equation are compared.Comment: 19 pages, 2 figure
Epidemiological Baseline of Influenza Virus in Wild Aquatic Birds in Hong Kong during the Pre-H5N1 Endemic Era
Influenza virus surveillance was conducted on wild ducks and shorebirds in Hong Kong at the Mai Po Nature Reserve to determine whether East Asian wild aquatic birds passing through or overwintering in Hong Kong are reservoirs of H5N1 influenza viruses and to establish an epidemiological baseline of influenza virus in wild aquatic birds during the pre-H5N1 endemic era. Three influenza viruses were isolated from 3178 faecal samples collected over three sampling periods from 1988 to 2001 during the southern and northern migration periods. The isolation rates and viruses were, respectively 0.08% (H10N5) in 1988 – 1990, 0.12% (H11N1) in 1998 and 0.09% (H3N8) in 1999 – 2001. Whereas tracheal and intestinal colon explants from representative shorebirds were susceptible to in vitro infection by the H10N5 virus, orally infected shorebirds were apparently not. Genetic analyses indicated that the nucleoprotein, matrix and nonstructural genes of the three viruses were related to those of aquatic bird viruses in Asia, but not to those of the human H5N1 virus. The present study provided epidemiological baseline information for future influenza virus surveillance in wild aquatic birds in southeast China
Calculation of symmetric and asymmetric vortex seperation on cones and tangent ogives based on discrete vortex models
An inviscid discrete vortex model, with newly derived expressions for the tangential velocity imposed at the separation points, is used to investigate the symmetric and asymmetric vortex separation on cones and tangent ogives. The circumferential locations of separation are taken from experimental data. Based on a slender body theory, the resulting simultaneous nonlinear algebraic equations in a cross-flow plane are solved with Broyden's modified Newton-Raphson method. Total force coefficients are obtained through momentum principle with new expressions for nonconical flow. It is shown through the method of function deflation that multiple solutions exist at large enough angles of attack, even with symmetric separation points. These additional solutions are asymmetric in vortex separation and produce side force coefficients which agree well with data for cones and tangent ogives
Process migration in UNIX environments
To support process migration in UNIX environments, the main problem is how to encapsulate the location dependent features of the system in such a way that a host independent virtual environment is maintained by the migration handlers on the behalf of each migrated process. An object-oriented approach is used to describe the interaction between a process and its environment. More specifically, environmental objects were introduced in UNIX systems to carry out the user-environment interaction. The implementation of the migration handlers is based on both the state consistency criterion and the property consistency criterion
