Tests of random walks and market efficiency in Latin American stock markets: An empirical note

This note examines the weak-form market efficiency of Latin American equity markets. Daily returns for Argentina, Brazil, Chile, Colombia, Mexico, Peru and Venezuela are examined for random walks using serial correlation coefficient and runs tests, Augmented Dickey-Fuller (ADF), Phillips-Perron (PP) and Kwiatkowski, Phillips, Schmidt and Shin (KPSS) unit root tests and multiple variance ratio (MVR) tests. The results, which are in broad agreement across the approaches employed, indicate that none of the markets are characterised by random walks and hence are not weak-form efficient, even under some less stringent random walk criteria.Emerging markets, random walk hypothesis, market efficiency

Pion production in p+p interactions and Be+Be collisions at the CERN SPS energies

Evidence for the onset of deconfinement in central Pb+Pb collisions was reported by NA49 in fixed target measurements at beam momentum 30A GeV/c. This observation motivated the NA61/SHINE program started in 2009 at the CERN SPS, which, in particular, aims to study properties of the onset of deconfinement by measurements of hadron production in proton-proton, proton-nucleus and nucleus-nucleus collisions. This contribution presents spectra of charged pions produced in p+p interactions and $^7$Be+$^9$Be collisions at 20A-158A GeV/c beam momentum. The NA61/SHINE results are compared with the corresponding NA49 data from central Pb+Pb collisions at the same beam momenta per nucleon

Observations on the cultivation of M.leprae and M. tuberculosis in medium V and V1

Skin scrapings from five different active sites were collected from 14 leprosy patients and inoculated into medium V. Shin scrapings from three leprosy patients were inoculated into medium V 1. All the cultures were incubated at 8-10°C. M. tuberculosis H37Rv, pretreatment isoloates and streptomycin resistant strains were inoculated into medium V, with and without antibiotics, and incubated at 8-10°C as well as 37°C. Smears were made from the M. leprae and M. tuberculosis cultures at 0 hours and at different time points. The number of bacilli in the smears were counted. There was no increase in the number of M. leprae or M. tuberculosis in any of the cultures

Fibras químicas. productos de alta estética

Se explica el significado de la expresión “fibras de alta tecnología”, las cuales se agrupan en fibras de altas prestaciones, fibras con funciones especiales y fibras de alta estética. Dentro de este último grupo se describen los productos símil-seda y los productos conocidos en Japón como “shin-gosen”, así como las tecnologías en las que se basa su fabricación.The meaning of the expression "high-technology fibres" is explained. These are grouped into high-performance fibres, special function fibres and aesthetically pleasing fibres. Within this latter group a description is provided of imitation silk products and what are known in Japan as “shin-gosen” fibres. The technologies employed for their manufacture are also described.L’étude explique l’expression “fibres de haute technologie”, lesquelles comprennent les fibres de hautes prestations, les fibres à fonctions spéciales et les fibres ultra-esthétiques. Le dernier groupe comprend les produits simili-soie et les produits connus au Japon sous le nom de “shin-gosen”; les technologies employées dans leur fabrication sont également décrites

Demand For International Reserves in ASEAN-5 Economies

The ASEAN-5 economies were observed to increase their demand for international reserves after the 1997 Asian financial crisis. This was coincided with their consistent current account surplus during the same period. Thus, this study attempts to investigate the existence of long-run relationship between reserve demand and current account for the period of 1997-2005. The Autoregressive Distributed Lag (ARDL) bounds test approach as proposed by Pesaran, Shin, and Smith (2001) was employed, and the empirical results revealed that current account surplus leads to the rise in the demand for international reserves in Indonesia, Malaysia, and Singapore.Bound Test, ARDL Approach, International Reserves, ASEAN-5

Development of High-Yielding and Early-Maturing Korean Hairy Vetch

There are a number of forage cultivars recommended by the government, but only a few winter-spring legumes are available for the farmers in Korea. Hairy vetch has superior winter hardiness and produces high dry matter (DM) yield compared with crimson clover, Persian clover, rose clover, common vetch and Chinese milk vetch in Korea. However, under a double cropping forage production system an early maturing vetch cultivar was more productive than a late maturing one (Shin et al., 2000). The objective of this research was to develop a high yielding and early flowering new hairy vetch cultivar derived from an accession in Korea

The Logic of Spectacle c. 1970

This paper examines the site plan and theme exhibit of the Osaka Expo of 1970, together with a week-long protest staged in the Tower of the Sun, which was the main element of the Theme Exhibit. Attempts to communicate a critical account of contemporary society and so transform the visitor were undercut by the Expo's ability to accommodate diverse interests and investments and to account for almost anything that was exhibited or staged on site. The Expo thus suggests that we need to supplement our understanding of spectacle as communication with an analysis of spectacle as a system
