An Experimental Investigation of Part-Of-Speech Taggers for Vietnamese

Part-of-speech (POS) tagging plays an important role in Natural Language Processing (NLP). Its applications can be found in many other NLP tasks such as named entity recognition, syntactic parsing and text chunking. Recent studies for common languages such as English and French gain very high precision for this core NLP task. However, current results for less common language like Vietnamese are not as good as for those languages. In our investigation, we utilized the techniques of two widely used toolkits, ClearNLP and Stanford POS Tagger, and made two new taggers to compare with three well-known Vietnamese taggers, namely JVnTagger, vnTagger and RDRPOSTagger. We created a unique evaluation scheme to make a systematic comparison and investigate that which tagger has the best accuracy and speed. The comparison revealed that our two new taggers built from ClearNLP and Stanford POS Tagger make overall accuracies of 94.50% and 94.39%, respectively, and outperform all other toolkits. Moreover, in our speed testing, RDRPOSTagger produces an impressive tagging speed and performs signiﬁcantly faster than any other stochastic taggers.
Effect of milk thistle [Silybum marianum L.] endosperm in the diet for cows on milk yield and fatty acid profiles

The experiment was carried out on 30 multiparous Black-and-White Lowland cows from 45 to 70 days of lactation, divided into three groups according to calving date and milk yield, and fed a basic ration consisting of maize, grass and sugar beet pulp silages with concentrate for the control group. In both of experimental groups, 20% of concentrate was substituted with endosperm from milk thistle {Sylibum marianum L. ) and 3% of calcium carbonate, but in one of the experimental groups, 1.5% of buffering sodium carbonate was additionally added to the concentrate mixture. Endosperm of milk thistle contained 23% fat with a high proportion of unsaturated fatty acids. The mean fat content in the milk of the experimental groups was similar (4.83 and 4.61%, respectively) but significantly higher (P<0.05) compared with the control group (4.27%). A decline in the percentage of short-chain (C 8. 0 C 1 0. 0, C 1 2. 0) and medium-chain (C 1 4 . 0 C 1 6. 0) fatty acids was observed along with a simultaneous advantageous, from the dietary point of view, increase in the percentage of unsaturated fatty acids (C l g . 0 A-6-c/s-C l g l A-9-12-c/s-C l g 2) in the milk of cows of the experimental groups.
OPTIMAL CONTROL OF STATE-DEPENDENT IMPULSE SYSTEMS

We study an optimal control problem for a measuredriven dynamic system, where jumps of a state trajectory may occur only at the moments of hitting a given set. The model can be described by using the complementarity formalism. The system is not assumed to satisfy correctness conditions. A time reparameterization technique is developed to reduce the optimization problem to the one with bounded controls. Necessary conditions for optimality are obtained by interpreting the Maximum Principle in the reduced problem.
Controls of Knowledge Production, Sharing and Use in Bureaucratized Professional Service Firms

One of the main obstacles to the current bureaucratization trend in large professional service firms (PSFs) is the organic nature of professional knowledge production, sharing and use. Centralized knowledge management (KM) systems aimed at codifying ‘best practice’ solutions to recurrent client questions for large-scale reuse are a common strategy increasingly employed to overcome this obstacle. Using a socio-ethnographic case study of a business law firm in Paris, this research examines whether the use of centralized KM systems in bureaucratized PSFs contributes to a shift in power from professionals to managers. More specifically, are administrative controls over knowledge resources increasing, or do professionals retain power (i.e. some level of social and self-control) over knowledge production, sharing and use? The results of this study indicate that, far from losing ground, professionals’ social and self-controls have been reinvented and reformed in a bureaucratized context.
The Effect of Chlorhexidine Mouth Rinse on the Colour Stability of Porcelain with Three Different Surface Treatments: An in Vitro Study

Statement of problem: The effect of mouth washes on discolouration of dental ceramics with different surface preparations is not well documented. Objectives: This in-vitro study has been conducted to evaluate the effect of chlorhexidine (CHX) mouth rinse on colour stability of overglazed (OP), autoglazed, (AP) or polished porcelain (POP) specimens. Materials and Methods: The restorative material investigated in this study was overglazed, autoglazed, or polished feldspathic porcelain. A total of 48 cylandrical specimens were prepared, (n=16 per each group). After baseline colour measurements, for a period of14 days 8 specimens of each group were immersed in 15 ml of 0.2% chlorhexidine mouth rinse twice daily for 2 min. After each immersion, the specimens were washed and stored in artificial saliva. Half of the specimens from each group were selected randomly as controls and stored in artificial saliva that was changed daily. The colour change (ΔE) of the specimens was measured by a spectrophotometer device. Data were statistically analyzed using 2-Way ANOVA followed by Tukey test Results: All the specimens displayed colour changes after immersion in chlorhexidine mouth rinse. POP specimens exhibited more colour change compared to AP and OP specimens (P=0.001). AP and OP specimens showed relatively the same colour change which was not significant compared to the control groups (P=0.9). Conclusion: Auto-glazed and over-glazed porcelain can tolerate chlorhexidine mouth rinse better than polished porcelain. However the colour changes of the ceramic with three different surface preparations were not perceivable clinically.
Rites of Passage, Rites of Academia: Facilitating the High School to College Transition through the Matriculation Process

The transition from high school to college can be challenging for many college bound students. In many colleges, polytechnics and universities today, administrators have put in place various strategies to facilitate a smooth high school-to-college transition for freshmen. In particular, Freshmen Orientation Programs (FOP) have been strategically used as a process towards the successful matriculation of students. This study is aimed to examine the Matriculation Process of freshmen through the theoretical lens of rites of passage. It employed participant observation and interviews, to examine pertinent issues of transition and adaptation of freshmen during the Matriculation Process at Ho Polytechnic. The findings revealed that FOPs which constituted the rites in the passage of transition from high school to the Polytechnic followed a process of ritualized phases akin to traditional rites of passage with the Ceremony of Matriculation as the crowning rite of incorporation. Post-matriculation evaluation interviews with participants showed that the Matriculation Process as an academic rite of passage was to a large extent effective in facilitating a smooth transition to life in the Polytechnic. Key w ords: Rites of Passage, Rites of Academia, Transition, Freshmen Orientation, Matriculation Process
(De)marketing to Manage Consumer Quality Inferences

Savvy consumers attribute a product's market performance to its intrinsic quality as well as the seller's marketing push. The authors study how sellers should optimize their marketing decisions in response. They find that a seller can benefit from “demarketing” its product, meaning visibly toning down its marketing efforts. Demarketing lowers expected sales ex ante but improves product quality image ex post, as consumers attribute good sales to superior quality and lackluster sales to insufficient marketing. The authors derive conditions under which demarketing can be a recommendable business strategy. A series of experiments confirm these predictions.
A Rule-Based Energy Management Strategy Based on Dynamic Programming for Hydraulic Hybrid Vehicles

Energy management strategy is very important for hydraulic hybrid vehicles to improve fuel economy. The rule-based energy management strategies are widely used in engineering practice due to their simplicity and practicality. However, their performances differ a lot from different parameters and control actions. A rule-based energy management strategy is designed in this paper to realize real-time control of a novel hydraulic hybrid vehicle, and a control parameter selection method based on dynamic programming is proposed to optimize its performance. Firstly, the simulation model of the hydraulic hybrid vehicle is built and validated by the data tested from prototype experimental platform. Based on the simulation model, the optimization method of dynamic programming is used to find the global optimal solution of the engine control for the UDDS drive cycle. Then, the engine control parameters of the rule-based energy management strategy are selected according to the engine control trajectory of the global optimal solution. The simulation results show that the 100 km fuel consumption of the proposed rule-based energy management strategy is 12.7L, which is very close to the global optimal value of 12.4L and is suboptimal.
The Tragedy of Our Legacy: How do Global Management Discourses Affect Small Scale Fisheries in the South?

Modern fisheries management discourse is supported by two fundamental narratives that have global impacts. One is the fear of open access regimes, and the other is the condemnation of catching under-sized and immature fish. These narratives have existed for more than half a century and originate from the common property theory and the maximum yield per recruit theory. Our aim is to critically discuss and evaluate these narratives which have been developed within the context of scientific management of single-species industrial fisheries. We will show that the underlying assumptions can be seriously wrong and particularly absurd in fluctuating multi-species, multi-gear artisanal fisheries. Fishing effort in small scale fisheries is often largely regulated by natural production, like other top predators, and many targeted fish stocks and fish communities display a high degree of resilience. Furthermore, in spite of common belief, small scale unregulated, non-selective, adaptive fishing patterns could be healthier and far more ecosystem conserving than the current imposed single species management strategies. Many of these fisheries are serving as a ‘social security system’ – a common good and thereby function as a ‘last resort’ for economic mishap. Limiting open access will undermine the role of small scale fisheries to provide insurance, particularly for the poorest and least advantaged. The immense pressure to adapt to modern fisheries management thinking and economic theory is based on flawed assumptions and will not only have negative social effects, but also negative biological effects.
DIVERSITY OF A DISEASE RESISTANCE GENE HOMOLOG IN ANDROPOGON GERARDII (POACEAE) IS CORRELATED WITH PRECIPITATION by MATTHEW ROUSE

Ecological clines often result in gradients of dise a pressure in natural plant communities, imposing a gradient of selection on di sease resistance genes. We describe the diversity of a resistance gene homolog in natural p opulations of the dominant tallgrass prairie grass, Andropogon gerardii, across a precipitation gradient ranging from 47.6 3 cm/year in western Kansas to 104.7 cm/year in central Missouri . Since moisture facilitates infection by foliar bacterial pathogens, plants along this preci pitation gradient will tend to experience heavier bacterial disease pressure to the east. In maize, the gene Rxo1 confers resistance to the pathogenic bacterium Burkholderia andropogonis. Rxo1 homologs have been identified in A. gerardii and B. andropogonis is known to infect natural populations of A. gerardii. The spatial genetic structure of A. gerardii was assessed from central Missouri to western Kans as by genotyping with AFLP markers. Samples were also gen otyped for Rxo1 homologs by amplifying an 810 base pair region of the leucine-rich repeat and digesting with restriction enzymes. We compared Rxo1 homolog diversity to AFLP diversity across differe nt spatial scales. Genetic dissimilarity based on AFLP markers was lower than would have occurred by chance at distances up to 30 m, and different prairies were m ore dissimilar than would have occurred by chance, but there was not a longitudinal trend in w ithin-prairie dissimilarity as measured by AFLP markers. Dissimilarity of the Rxo1 homologs was higher in the east suggesting the presence of diversifying selection in the more dise ase-conducive eastern environments.
Risk factors and knowledge of the elderly people about chronic kidney disease

Objective: to analyze the relationship between the risk factors and the elderly people knowledge about chronic kidney disease. Methods: this study is a cross-sectional research with 100 elderly enrolled in basic units, using asemi-structured interview. Data were analyzed using descriptive and inferential statistics. Results: most elderly people had adequate knowledge about the disease and prevention, but poor knowledge about hemodialysis. Regarding the risk factors in the elderly investigated, increased are highlighted and statistical significance of waist circumference (p=0.049), smoking (p=0.022) and alcohol consumption (p=0.013). Conclusion: relationships between risk factors as smoking, alcoholism, increased abdominal circumference, and the knowledge of the elderly about chronic kidney disease were identified.
Fire persistence traits of plants along a productivity and disturbance gradient in mediterranean shrublands of south‐east Australia

Aim To understand changes in fire persistence traits of plants along a latitudinal gradient, considering the interactions between productivity, community (fuel) structure and fire regime. Location A gradient in the south of Australia (latitude 33‐37 ° S; longitude 140‐ 143 ° E), including: Little Desert National Park (VIC), Big Desert Wilderness Park (VIC), Murray-Sunset National Park (VIC), Danggali Conservation Park (SA) and Ta rawi Nature Reserve (NSW). Methods We selected four areas along a latitudinal gradient for which information on fire history and vegetation was available. Then, we tested to what extent the four selected areas have different climate and different fire regimes. Plant cover values of different life forms provided an indication of the plant community structure and flammability, and the proportion of species with different fire persistence traits (resprouting, seedbank persistence) informed us on the trait selection. Results Precipitation decreases and temperature increases from south to north. Thus the selected sites represent a gradient from high productivity (low aridity) in the south to low productivity (high aridity) in the north. Fire statistics suggest that fire frequency parallels productivity. There is a tendency for life form dominance and community structure to shift in such a way that fuel connectivity is reduced towards the north. Resprouting species increase and obligate seeders decrease along the fire‐productivity gradient. Main conclusions Changes in plant traits are difficult to understand without simultaneous consideration of both the disturbance and the productivity gradients. In our study area, fire regime and productivity interact in such a way that decreases in productivity imply changes in fuel structure that produce a reduction in fire frequency. Resprouting species are better represented at the high fire‐productivity part of the gradient, while obligate seeders are better represented at the opposite end of the gradient. The results also emphasize the importance of considering not only climate changes but also changes in fuel structure to predict future fire regimes.
Stochastic Analysis of a Queue Length Model Using a Graphics Processing Unit

Mathematical modeling is an inevitable part of system analysis and design in science and engineering. When a parametric mathematical description is used, the issue of the parameter estimation accuracy arises. Models with uncertain parameter values can be evaluated using various methods and computer simulation is among the most popular in the engineering community. Nevertheless, an exhaustive numerical analysis of models with numerous uncertain parameters requires a substantial computational effort. The purpose of this paper is to show how the computation can be accelerated using a parallel configuration of graphics processing units (GPU). The assessment of the computational speedup is illustrated with a case study. The case study is a simulation of Highway Capacity Manual 2000 Queue Model with selected uncertain parameters. The computational results show that the parallel computation solution is efficient for a larger amount of samples when the initial and communication overhead of parallel computation becomes a sufficiently small part of the whole process.
Experimental analysis of parallel plate and crosscut pin fin heat sinks for electronic cooling applications

Experimental investigation of parallel plate fin and the crosscut pin fin heat sinks where the heating element placed asymmetrically is performed. Theoretical calculations were done and compared with the experimental results. A comparative study was made based on their efficiencies, heat transfer coefficient, and the thermal performance. From the experimental results it was found that the average heat transfer coefficient of parallel plate fins is higher than that of crosscut pin fins with many perforations. However the performance efficiency of both the crosscut pin fins and parallel plate fins is similar. A hybrid approach was employed to significantly optimize the distance between the fan and heat sink for parallel plate and crosscut pin fins. Parallel plate heat sink with an average heat transfer coefficient of 46 W/m²K placed at an optimum fan distance of 40-60 mm is selected as the suitable choice for the micro-electronic cooling when the heating element is placed asymmetrically.
REGULATION OF THE PROVISION OF PUBLIC GOODS FROM AGRICULTURE: ECONOMIC VALUE BASED MODEL

The paper focuses on the provision of agricultural public goods and its economic regulation. Beyond supplying food and fiber, agricultural activity can also be instrumental in forming the landscape, providing natural resources, and preserving biodiversity. Fur-thermore, agriculture contributes to the achievement of societal goals such as the viability of rural areas and their development, food security, and preservation of cultural heritage. Agriculture may also have positive spill-over effects on other economic sectors such as tourism. Positive externalities of agriculture result in the emergence the said public goods, whereas intensive environmentally unbal-anced agricultural activity causes damage to the environment. The need of boosting the positive agricultural externalities, creating a provision system of agricultural public goods, and keeping under control the negative externalities can not be ignored. In the context of the provision of public goods from agriculture, scientists encounter difficulties with evaluating those goods. No markets exist for them, it is not possible to exclude them from public consumption or to impose a tax on their use. Moreover, valua-tion problems result from a number of factors, namely: agricultural economic processes are coherent with biological processes, pro-duction proceeds on a large territory, etc. When the demand and supply conditions of agricultural public goods are unknown, prob-lems with estimating their value and importance readily occur. No volume of similarly provided public goods can be defined as op-timal with regard to a society. The absence of scientifically reasoned methodological principles or a specific valuation methodology for agricultural public goods prevents from rationalizing the economic regulation of the provision of public goods from agriculture and securing the quantities of agricultural public goods required by the consumers. To ensure economically grounded volumes of agricultural public goods, it is essential to develop an efficient economic regulation system for the provision of public goods and to produce an economic value based model of the regulation of agricultural public goods provision.
Corporate Social Responsibility in Forming Corporate Image

This article analyses the impact corporate social responsibility has on corporate image, basing the findings theoretically and empirically. The first part of this article focuses on a theoretical concept of corporate social responsibility. The authors analyze different definitions of corporate social responsibility, review chronological development of this concept and reveal similarities between different definitions. Positive and negative positions towards corporate social responsibility are presented and compared. The second part of this article reveals the theoretical concept of corporate image and the constituting factors. After discussing different definitions of corporate image, concluding remarks are made. The authors of this article discuss the topicality of corporate image management subsequently and name the factors that form corporate image, laying out the basis to manage particular factors. The first two parts of this paper provide a theoretical basis for further discussion. The third part of this article outlines insights for causality between corporate social responsibility and corporate image as well as links between the two. Concluding the reviewed literature and the newest empirical data, it is noted that corporate social responsibility has positive impact on corporate image. Positive impact can be seen through various phenomena: positive consumer attitude, positive word of mouth, etc. Theoretical studies lay the basis for creating a structural model of corporate social responsibility impact on corporate image, which presents the impact corporate social responsibility has on corporate image. In addition to previously discussed theoretical concepts, three factors forming corporate image (corporate marketing communications, corporate social responsibility and consumer demographic characteristics) are detailed. Structural model is based on LeBlanc (1995), van Riel, Balmer (1997) and Chattananon, Lawley (2007) models. Newly proposed structural model links earlier models into one single system. The new structural model is thoroughly examined using empirical research and the importance of each constituting factor is defined. The results of the empirical research reveals that corporate social responsibility has positive impact on corporate image though it is not the most important factor. Surprisingly none of demographic characteristics determines consumer attitude towards corporate image. The results of empirical research and literature studies allow to draw the conclusions and raise proposals. http://dx.doi. org/10.5755/j01.ee. 22.5. 972
