We investigated optimal conditions for characterization of bioactivity of lytic compound(s) excreted by Alexandrium tamarense based on a cell-bioassay system. Allelochemical response of the cryptophyte Rhodomonas salina indicated the presence oflytic compound(s) in a reliable and reproducible way and allows for quantification of this lytic effect. The parameters tested were the incubation time of putatively lytic extracts or fractions with the target organism R. salina, different techniques for cell harvest from A. tamarense cultures and the optimal harvest time. A three hour incubation time was found to be optimal to yield a rapid response while accurately estimating effective concentration (ECso) values. Harvest of A. tamarense cultures by filtration resulted in loss of lytic activity in most cases and centrifugation was most efficient in terms of recovery of lytic activity. Maximum yield of extracellular lytic activity of A. tamarense cultures was achieved in the stationary phase. Such optimized bioassay guided fractionation techniques are a valuable asset in the isolation and eventual stmctural elucidation of the unknown lytic substances.

Institutional Development of Capital Markets in Nine Asian Economies

This paper is conducting a comparative analysis of the development of securities markets in nine Asian economies: Korea, Taiwan, Hong Kong, Singapore, Malaysia, Thailand, Indonesia, the Philippines, and China. This study focuses on two aspects: the history and institutional development of securities market, such as legal systems, payment systems, etc. From the analyses, this paper reveals several common features of the development of securities markets in nine Asian economies. First, most economies had an informal capital market in the early period of their history. Second, the background of the foundation of their official markets was influenced by experiences of colonization. Third, most governments recognized the importance of the capital market for economic development and had a positive attitude in promoting the market. Fourth, statistics clearly showed that most economies experienced several booms in their capital market from the late 1980s.

Foreign Direct Investment Relations between Myanmar and ASEAN

Myanmar highly appreciates foreign direct investment (FDI) as a key solution reducing the development gap with leading ASEAN countries. Accordingly, it is welcomed by the government. Myanmar's Foreign Investment Law was enacted in 1988 soon after the adoption of a market-oriented economic system to boost the flow of FDI into the country. Foreign investors positively responded to these measures in the early years and FDI inflow into Myanmar gradually increased during the period from 1989 to 1996. However, after 1997, FDI inflow was dramatically reduced and markedly declined until 2004. In 2005, FDI inflow increased at an unprecedented rate and reached the highest level in the country's history. However, this growth was not sustainable in the subsequent years, as it declined again and turned stagnant at the previous level. In terms of source regions, ASEAN is a major investor in Myanmar, which investment is significantly exceeds the combined investment of other regions of the world. Among top ten countries, Thailand's investment alone is significantly more than combined total investments of the other nine countries. Next to Thailand in terms of investments in Myanmar are Singapore and Malaysia among ASEAN, at second and third places, respectively. The combined total FDI inflows into the power and oil and gas sector represent about 65 percent of the total investment. There are many opportunities for foreign investment in other sectors, which are not, yet exploited. ASEAN countries will certainly be source countries of Myanmar FDI in the future, and Myanmar should expand to other Asian countries like Japan, India, China, Korea, and Hong Kong where its FDI portfolio is concerned. To effectively attract FDI into the country, Myanmar needs to minimize the effect of policy while opening and encouraging other potential sectors of FDI to foreign investors in ASEAN and Asian countries.

In-loop Feature Tracking for Structure and Motion with Out-of-core Optimization

In this paper, a novel and approach for obtaining 3D models from video sequences captured with hand-held cameras is addressed. We define a pipeline that robustly deals with different types of sequences and acquiring devices. Our system follows a divide and conquer approach: after a frame decimation that pre-conditions the input sequence, the video is split into short-length clips. This allows to parallelize the reconstruction step which translates into a reduction in the amount of computational resources required. The short length of the clips allows an intensive search for the best solution at each step of reconstruction which robustifies the system. The process of feature tracking is embedded within the reconstruction loop for each clip as opposed to other approaches. A final registration step, merges all the processed clips to the same coordinate frame

A comparative study on unconstrained hand biometrics

Biometrics applied to mobile devices are of great interest for security applications. Daily scenarios can benefit of a combination of both the most secure systems and most simple and extended devices. This document presents a hand biometric system oriented to mobile devices, proposing a non-intrusive, contact-less acquisition process where final users should take a picture of their hand in free-space with a mobile device without removals of rings, bracelets or watches. The main contribution of this paper is threefold: firstly, a feature extraction method is proposed, providing invariant hand measurements to previous changes; second contribution consists of providing a template creation based on hand geometric distances, requiring information from only one individual, without considering data from the rest of individuals within the database; finally, a proposal for template matching is proposed, minimizing the intra-class similarity and maximizing the inter-class likeliness. The proposed method is evaluated using three publicly available contact-less, platform-free databases. In addition, the results obtained with these databases will be compared to the results provided by two competitive pattern recognition techniques, namely Support Vector Machines (SVM) and k-Nearest Neighbour, often employed within the literature. Therefore, this approach provides an appropriate solution to adapt hand biometrics to mobile devices, with an accurate results and a non-intrusive acquisition procedure which increases the overall acceptance from the final user.

The effect of depression on balance decline in mature women

Depression has been identified as a risk factor for falls, and a change in balance ability over time has yet to be investigated. This study aimed to identify if, over a 3-year period, balance ability changed in 26 women who were on medication for depression, compared to 26 non-depressed women. The two groups were matched for age, number of co-morbidities, activity level, medications, and height. All participants were simultaneously enrolled in a larger, longitudinal study of ageing. Balance measures included the Functional Reach (FR) test, Lateral Reach (LR) test, Step Test (ST), Timed Up and Go, and the Modified Clinical Test of Sensory Integration and Balance, Unilateral Stance (ULS) and Limit of Stability (LOS) laboratory tests. Results showed a significant difference between the groups on ST, right ULS (eyes closed) and forward end point excursion of the LOS. There was no difference in the number of falls between groups. Analysis of the depressed group alone showed that right FR declined significantly and left and right LR tended towards decline, but not differently between groups. There was no between-group differences for these measures. There was no significant decline in non-depressed women for any measurement. Depressed women have less ability to maintain their balance than non-depressed women, and should be encouraged to participate in appropriate activities known to improve or maintain balance.

Conditional risk, return and contagion in the banking sector in Asia

This paper investigates risk and return in the banking sector in three Asian markets of Taiwan, China and Hong Kong. The study focuses on the risk-return relation in a conditional factor GARCH-M framework that controls for time-series effects. The factor approach is adopted to incorporate intra-industry contagion and an analysis of spillovers between large banks and small banks. Finally, the study provides evidence on these relations before and after the Asian financial crisis of 1997. The results are generally consistent across the markets and with expectations.

What is English for? Language structure and the curriculum for English

This article uses Bernstein’s theory of pedagogic discourse to account for both the processes by which curriculum change occurs and the failure of efforts to introduce meaningful attention to language structure into national curricula.

Psychological contract breach in a Chinese context:an integrative approach

This study examined the antecedents and outcomes of psychological contract breach as well as why and how psychological contract breach is related to these outcomes. Respondents were Hong Kong Chinese employees (N=152). Results showed organizational change and history of contract breach to be related to psychological contract breach which, in turn, was related to turnover intentions, psychological withdrawal behaviour, and civic virtue. Further, trust in employer fully mediated the relationship between psychological contract breach and the work outcomes of psychological withdrawal behaviour and civic virtue but partially mediated the psychological contract breach–turnover intentions relationship. Lastly, interactional justice failed to moderate the relationship between psychological contract breach and the work outcomes.

A political economy of the ethnic chinese catering industry

The present political climate in which the ideals of entrepreneurship and self-help are strongly encouraged has drawn attention to those ethnic minorities noted for their entrepreneurial activity. Since the Chinese appear to be an exemplary case in point, this thesis focusses upon the historical material conditions which have led to the formation of a Chinese 'business* community in Britain, both past and present As such, it rejects the theories of cultural determinism which characterise most studies of the Chinese. For rather than representing the endurance of cultural norms, the existence of the contemporary Chinese 'niche' of ethnically exclusive firms in the catering industry is due to the conjunction of a number of historical processes. The first is the imperialist expansion into China of Britain's capitalist empire during the nineteenth century which established a relationship of dependency upon the interests of British capital by colonial Chinese labour. The second is the post war development of the catering industry and its demand for cheap labour as administered by the British state together with the contemporaneous development of the agricultural economy of colonial Hong Kong. Far from representing a source of material benefit to all, the ethnic Chinese 'niche' in catering is highly exploitative and merely underlines the racial oppression of Chinese in Britain. Attempts to promote business interests within the ethnic community therefore serve merely to entrench the structures of oppression.

Uses of frontier efficiency methodologies and multi-criteria decision making for performance measurement in the energy sector This special issue aims to focus on holistic, applied research on performance measurement in energy sector management and for publication of relevant applied research to bridge the gap between industry and academia. After a rigorous refereeing process, seven papers were included in this special issue. The volume opens with five data envelopment analysis (DEA)-based papers. Wu et al. apply the DEA-based Malmquist index to evaluate the changes in relative efficiency and the total factor productivity of coal-fired electricity generation of 30 Chinese administrative regions from 1999 to 2007. Factors considered in the model include fuel consumption, labor, capital, sulphur dioxide emissions, and electricity generated. The authors reveal that the east provinces were relatively and technically more efficient, whereas the west provinces had the highest growth rate in the period studied. Ioannis E. Tsolas applies the DEA approach to assess the performance of Greek fossil fuel-fired power stations taking undesirable outputs into consideration, such as carbon dioxide and sulphur dioxide emissions. In addition, the bootstrapping approach is deployed to address the uncertainty surrounding DEA point estimates, and provide bias-corrected estimations and confidence intervals for the point estimates. The author revealed from the sample that the non-lignite-fired stations are on an average more efficient than the lignite-fired stations. Maethee Mekaroonreung and Andrew L. Johnson compare the relative performance of three DEA-based measures, which estimate production frontiers and evaluate the relative efficiency of 113 US petroleum refineries while considering undesirable outputs. Three inputs (capital, energy consumption, and crude oil consumption), two desirable outputs (gasoline and distillate generation), and an undesirable output (toxic release) are considered in the DEA models. The authors discover that refineries in the Rocky Mountain region performed the best, and about 60 percent of oil refineries in the sample could improve their efficiencies further. H. Omrani, A. Azadeh, S. F. Ghaderi, and S. Abdollahzadeh presented an integrated approach, combining DEA, corrected ordinary least squares (COLS), and principal component analysis (PCA) methods, to calculate the relative efficiency scores of 26 Iranian electricity distribution units from 2003 to 2006. Specifically, both DEA and COLS are used to check three internal consistency conditions, whereas PCA is used to verify and validate the final ranking results of either DEA (consistency) or DEA-COLS (non-consistency). Three inputs (network length, transformer capacity, and number of employees) and two outputs (number of customers and total electricity sales) are considered in the model. Virendra Ajodhia applied three DEA-based models to evaluate the relative performance of 20 electricity distribution firms from the UK and the Netherlands. The first model is a traditional DEA model for analyzing cost-only efficiency. The second model includes (inverse) quality by modelling total customer minutes lost as an input data. The third model is based on the idea of using total social costs, including the firm’s private costs and the interruption costs incurred by consumers, as an input. Both energy-delivered and number of consumers are treated as the outputs in the models. After five DEA papers, Stelios Grafakos, Alexandros Flamos, Vlasis Oikonomou, and D. Zevgolis presented a multiple criteria analysis weighting approach to evaluate the energy and climate policy. The proposed approach is akin to the analytic hierarchy process, which consists of pairwise comparisons, consistency verification, and criteria prioritization. In the approach, stakeholders and experts in the energy policy field are incorporated in the evaluation process by providing an interactive mean with verbal, numerical, and visual representation of their preferences. A total of 14 evaluation criteria were considered and classified into four objectives, such as climate change mitigation, energy effectiveness, socioeconomic, and competitiveness and technology. Finally, Borge Hess applied the stochastic frontier analysis approach to analyze the impact of various business strategies, including acquisition, holding structures, and joint ventures, on a firm’s efficiency within a sample of 47 natural gas transmission pipelines in the USA from 1996 to 2005. The author finds that there were no significant changes in the firm’s efficiency by an acquisition, and there is a weak evidence for efficiency improvements caused by the new shareholder. Besides, the author discovers that parent companies appear not to influence a subsidiary’s efficiency positively. In addition, the analysis shows a negative impact of a joint venture on technical efficiency of the pipeline company. To conclude, we are grateful to all the authors for their contribution, and all the reviewers for their constructive comments, which made this special issue possible. We hope that this issue would contribute significantly to performance improvement of the energy sector.
