Floating Exchange Rate Regime

In recent years, many developing countries having a history of high inflation, unfavorable balance of payment situation and a high level of foreign currencies denominated debt, have switched or are in the process of switching to a more flexible exchange rate regime. Therefore, the stability of the exchange rate and the dynamics of its volatility are more crucial than before to prevent financial crises and macroeconomic disturbances. This paper is designed to find out the reasons behind Bangladesh’s exit to floating exchange rate system and evaluate its performance under the new regime. It’s found that, the shift to market based floating exchange rate for the Taka was a major step towards protecting the country’s external competitiveness and insulating the country from adverse external shocks. The comparisons of selected economic indicators during the first three year’s experience under the new regime showed an impressive effect on the economy of Bangladesh specially export growth, low volatility of exchange rate, towering foreign exchange reserve etc.Floating exchange rate, foreign currency liquidity, trade openness, exchange rate volatility, inflation

Very low bit-rate video coding focusing on moving regions using three-tier arbitrary-shaped pattern selection algorithm

Very low bit-rate video coding using patterns to represent moving regions in macroblocks exhibits good potential for improved coding efficiency. Recently an Arbitrary Shaped Pattern Selection (ASPS) algorithm and its Extended version(EASPS) were presented, that used a dynamically extracted set of patterns, of the two different sizes, based on actual video content. These algorithms, like other pattern matching algorithms failed to capture a large number of active-region macroblocks (RMB) especially when the object moving regions is relatively larger in a video sequence. As the size of the moving object may vary, superior coding performance is achievable by using dynamically extracted patterns of a larger size. This paper, proposes a three-tier Arbitrary Shaped Pattern Selection (ASPS-3) algorithm that uses three different pattern sizes for very low bit ate coding. Experimental results show that ASPS-3 exhibits better performance compared with other pattern matching algorithms, including the low-bit rate video coding standard H.263

Import Protection, Capital Inflows, and Real Exchange Rate Dynamics

This paper focuses on the effect of import protection on the response of the real exchange rate to capital flows. The central hypothesis is that barriers to imports blunt the expenditure and production shifting effects of changes in relative prices, and hence the ability of the real exchange rate to equilibrate the economy in response to international capital flows. Employing a cross-section approach, the study focuses on three broadly similar countries but with very different levels of protection: Argentina, Australia, and Canada. The empirical results are consistent with the central hypothesis.import protection; real exchange rate

Motivating factors in online language teacher education in southern Argentina

Online teacher education is of growing interest and so is the study of motivation as a key factor in technology-mediated learning environments. This study is based on a pre-service language teacher education programme in Patagonia, a southern Argentinian region with no face-to-face training offers, limited Internet access and a large number of unqualified teachers. Our goal is to broaden the understanding of online teacher education programmes at undergraduate level in contexts where most trainees are practicing teachers and where online education is the only possibility for holding a teaching qualification. We focused on the motivating factors that led 71 trainees to enrol and to remain in this online teacher training course. Through a mixed methods approach, the trainees completed an online survey (n = 71) and participated in a follow-up interview (n = 24). Results showed that obtaining a teaching degree, autonomy, and individual activities were key factors in initial and sustaining motivation. Participants' experiences challenged collaborative learning in an online environment

A directionally based bandwidth reservation scheme for call admission control

This paper proposes a new advanced Call Admission Control(CAC) strategy involving for the first time, a bandwidth reservation scheme that is influenced by the direction attribute of a mobile terminal (MT). Aside from the Quality-of-Service (QoS) parameters, the direction attribute plays a key role in efficiently reserving resources for MTs supporting multimedia communications for different QoS classes. The framework for a direction-based CAC system is entirely distributed and may be viewed as a message passing system, where MTs inform their neighbouring base stations (BS) not only of their QoS requirements, but also of their mobility parameters. The base stations then predict future demand and reserve resources accordingly, only admitting those terminals that can be adequately supported. The bandwidth reservation scheme proposed in this paper, integrates the direction attribute into the conventional Guard Channel (GC) scheme. Simulation results prove that this new scheme offers significant improvements in both Call Blocking Probability (CBP) and bandwidth utilization, under a variety of differing traffic conditions

Jóvenes y adolescentes en escuelas secundarias de la ciudad de La Plata : Opiniones de sus clases de EF

El presente trabajo se realizó en el marco de la cátedra de Educación Física 3 como monografía para la promoción de la misma. Se parte de la idea de que no existe un adolescente ideal o único sino que existen adolescentes, cada uno con necesidades distintas, inquietudes diversas y disímiles ganas de aprender. En esta ponencia se intentará dar cuenta de qué papel cumple la Educación Física en su trayecto de formación secundaria, como así también que opinión tienen los jóvenes acerca de las clases de Educación Física en sus establecimientos escolares.Eje 5: Las prácticas de la Educación Física vinculadas con la integración e inclusión social.
