Towards a complete multiple-mechanism account of predictive language processing [Commentary on Pickering & Garrod]
Although we agree with Pickering & Garrod (P&G) that prediction-by-simulation and prediction-by-association are important mechanisms of anticipatory language processing, this commentary suggests that they: (1) overlook other potential mechanisms that might underlie prediction in language processing, (2) overestimate the importance of prediction-by-association in early childhood, and (3) underestimate the complexity and significance of several factors that might mediate prediction during language processing
Integrating Pharmacotherapy and Psychotherapy for Paediatric Bipolar Disorder: Translating Science to Service
Objective: For comprehensive management of paediatric bipolar disorder (PBD), it is imperative to combine psychopharmacotherapy
with specific psychotherapy. This article proposes a model that incorporates (1) an overview of psychopathology, (2) a review of
outcomes in psychopharmacotherapy trials, and (3) a summary of evidence-based forms of psychotherapy to complement
pharmacotherapy. Results: The psychopathology of PBD is unique compared to that of adult bipolar disorder with prominent
irritability, rapid cycling, high rates of co-morbid attention deficit hyperactivity disorder, mixed episodes and chronicity. Combination
therapy with a second generation antipsychotic and a mood stabilizer is proving to be more effective than monotherapy with a mood
stabilizer. Empirical findings for the support of family-focused, cognitive behavioral therapies with individual family or multifamily
psychoeducation groups suggest that these psychosocial treatments are valuable complementary tools for clinicians who treat youths
diagnosed with PBD. Conclusion: As pharmacotherapy and psychotherapy are most beneficial when applied together, the clinician’s
understanding of the science behind these forms of treatment is likely to be of great value in effectively providing services to youths
diagnosed with PBD
Investigation of supersonic chemically reacting and radiating channel flow
The 2-D time-dependent Navier-Stokes equations are used to investigate supersonic flows undergoing finite rate chemical reaction and radiation interaction for a hydrogen-air system. The explicit multistage finite volume technique of Jameson is used to advance the governing equations in time until convergence is achieved. The chemistry source term in the species equation is treated implicitly to alleviate the stiffness associated with fast reactions. The multidimensional radiative transfer equations for a nongray model are provided for a general configuration and then reduced for a planar geometry. Both pseudo-gray and nongray models are used to represent the absorption-emission characteristics of the participating species. The supersonic inviscid and viscous, nonreacting flows are solved by employing the finite volume technique of Jameson and the unsplit finite difference scheme of MacCormack. The specified problem considered is of the flow in a channel with a 10 deg compression-expansion ramp. The calculated results are compared with those of an upwind scheme. The problem of chemically reacting and radiating flows are solved for the flow of premixed hydrogen-air through a channel with parallel boundaries, and a channel with a compression corner. Results obtained for specific conditions indicate that the radiative interaction can have a significant influence on the entire flow field
Investigation of chemically reacting and radiating supersonic internal flows
The two-dimensional spatially elliptic Navier-Stokes equations are used to investigate the chemically reacting and radiating supersonic flow of the hydrogen-air system between two parallel plates and in a channel with a ten degree compression-expansion ramp at the lower boundary. The explicit unsplit finite-difference technique of MacCormack is used to advance the governing equations in time until convergence is achieved. The chemistry source term in the species equation is treated implicitly to alleviate the stiffness associated with fast reactions. The tangent slab approximation is employed in the radiative flux formation. Both pseudo-gray and nongray models are used to represent the absorption characteristics of the participating species. Results obtained for specific conditions indicate that the radiative interaction can have a significant influence on the flow field
Transport study of Berry's phase, the resistivity rule, and quantum Hall effect in graphite
Transport measurements indicate strong oscillations in the Hall-,,
and the diagonal-, , resistances and exhibit Hall plateaus at the
lowest temperatures, in three-dimensional Highly Oriented Pyrolytic Graphite
(HOPG). At the same time, a comparative Shubnikov-de Haas-oscillations-based
Berry's phase analysis indicates that graphite is unlike the GaAs/AlGaAs 2D
electron system, the 3D n-GaAs epilayer, semiconducting ,
and some other systems. Finally, we observe the transport data to follow
. This feature is consistent with
the observed relative phases of the oscillatory and .Comment: 5 pages, 4 figure
Observation of linear-polarization-sensitivity in the microwave-radiation-induced magnetoresistance oscillations
In the quasi two-dimensional GaAs/AlGaAs system, we investigate the effect of
rotating \textit{in-situ} the electric field of linearly polarized microwaves
relative to the current, on the microwave-radiation-induced magneto-resistance
oscillations. We find that the frequency and the phase of the photo-excited
magneto-resistance oscillations are insensitive to the polarization. On the
other hand, the amplitudes of the magnetoresistance oscillations are remarkably
responsive to the relative orientation between the microwave antenna and the
current-axis in the specimen. The results suggest a striking
linear-polarization-sensitivity in the radiation-induced magnetoresistance
oscillations.Comment: 4 figures, 5 page
PUBLIC INVESTMENT IN AGRICULTURAL AND GDP GROWTH-- ANOTHER LOOK AT THE INTER SECTORAL LINKAGES AND POLICY IMPLICATIONS
Despite its reduced share in India’s GDP, agriculture continues to have a strategic importance in ensuring its overall growth and prosperity. As part of the new economic policy package introduced in the early nineties, there has been a reduction in the rate of public investment. While this may not be bad for the industrial sector, the impact of this policy on agriculture is a matter of concern, in sofar as it not only affects steady growth of agriculture but also influences the overall performance of the economy. This is more so because the agricultural sector public investment has also promoted private investment by way of what is termed as the crowding-in phenomenon. This phenomenon together with inter-sectoral linkages is used in this paper to examine the effect of higher public investment for agriculture on the stable growth of this sector as well as of the entire economy. Policy implications of this exercise are important for obvious reasons.Sectoral linkages, Public Investment, crowding-in
