UDC 519 . 254 MSC 68 H 30 Volatility in Classification

The goal of the presented work consists in the construction of the new three-levels scheme of authomatical classification. This scheme is based on the newly introduced notion of volatility of separate clusters as well as of whole classification. The property is exactly defined and efficiently calculated. It describes the stability, exactness, validity of subsets of the given initial set – in essence, their possibility (or impossibility) to be selected as clusters. The suggested algorithm finds the clusters with arbitrary levels of volatility, including the conventional case of zero volatility. The clusters in USA, Russia and Sweden stock market (for crisis period of 2008-2010) and deputies clusters based on voting results in the 3rd State Duma between September 2001 and January 2002 (the period including the creation of the party ”United Russia” 01.12.2001) were constructed by the suggested algorithm. Analyzing clusters constructed basing on the voting results for every of the considered months, it has turned out that the clustering volatility was equal to zero in September and October, drastically increased in November and slightly decreased in December and January. But several indices (i.e. concordance of parties’ positions) did not show sensible jumps near this political ”bifurcation point”. The other considered various model examples demonstrated the results well-coordinated with geometrical intuition.
The Constructivist Paradigm and Some Implications for Science Content and Pedagogy

Through a comparison of the widely-held traditional view of science with the constructivist view of science, we argue that the constructivist view of the content of science has important implications for classroom teaching and learning. This alternative view of science concepts as human constructs, scrutinised by application of the rules of the game of science, raises many challenges for teachers. Reconceptualisation of teachers' views of the nature of science and of learning in science is important for a constructivist pedagogy. We argue here that open discussion of the 'rules of the game' of science would contribute to better learning in the classroom, since learners would be better equipped to change their existing concepts by knowing more about the nature of science itself.
Geospatial data pre-processing on watershed datasets: A GIS approach

Spatial data mining helps to identify interesting patterns from the spatial data sets. However, geo spatial data requires substantial data pre-processing before data can be interrogated further using data mining techniques. Multi-dimensional spatial data has been used to explain the spatial analysis and SOLAP for pre-processing data. This paper examines some of the methods for pre-processing of the data using Arc GIS 10.2 and Spatial Analyst with a case study dataset of a watershed.
DNA barcoding of marine polychaetes species of southern Patagonian fjords

Accurate species identification remains a basic first step in any study of biodiversity, particularly for global changes and their consequences. Thus, there is a pressing need for taxonomic expertise in a broad range of taxa. DNA barcoding has proved to be a powerful alternative method to traditional morphological approaches, allowing to complement identification techniques for living organisms. In this study, we assess intraspecific and interspecific genetic divergence among marine polychaetes from Patagonian fjords of southern Chile, using mitochondrial Cytochrome c Oxidase Subunit I (COI) gene. Our results showed that a total of 13 polychaetes species identified in this study exhibited high levels of interspecific variation among 31 analyzed sequences. Mean pairwise sequence distances comparisons based on K2P within species ranged from 0.2 to 0.4%. In contrast, interspecific comparisons were much higher and ranged between 18 to 47%, with the exception of the congeneric species Asychis chilensis and Asychis amphiglypta that showed high levels of genetic similarities and absence of reciprocal monophyly. This study presents the first information on DNA barcoding for polychaetes species in the southern Chile, and it establishes the effectiveness of DNA barcoding for identification of marine polychaetes species from Patagonian Fjords, thus making it available to a much broader range of scientists.
Microeconomic foundations for macroeconomic structure

The models used in economic theory, though necessarily abstract, should be consistent with the nature of decision making behavior. A formal metaphor of individual behavior as a continuous flow indicates certain requirements that theories of consumer, producer, and economywide behavior should exhibit. A family of discrete time, recursive optimizing models is suggested as the appropriate building block for further developing dynamic economic theory.
Comparative Study on Facial Expression Recognition using Gabor and Dual-Tree Complex Wavelet Transforms

Moving from manually interaction with machines to automated systems, stressed on the importance of facial expression recognition for human computer interaction (HCI). In this article, an investigation and comparative study about the use of complex wavelet transforms for Facial Expression Recognition (FER) problem was conducted. Two complex wavelets were used as feature extractors; Gabor wavelets transform (GWT) and dual-tree complex wavelets transform (DT-CWT). Extracted feature vectors were fed to principal component analysis (PCA) or local binary patterns (LBP). Extensive experiments were carried out using three different databases, namely; JAFFE, CK and MUFE databases. For evaluation of the performance of the system, k-nearest neighbor (kNN), neural networks (NN) and support vector machines (SVM) classifiers were implemented. The obtained results show that the complex wavelet transform together with sophisticated classifiers can serve as a powerful tool for facial expression recognition problem.
An Oil and Gas Model

This paper formulated a short-run model, with an explicit role for monetary policy, for analyzing world oil and gas markets. The model described carefully the parameters of these markets and their vulnerability to business cycles. Estimates showed that short-run demand for oil and gas was price- inelastic, relatively income-elastic, and was influenced by interest and exchange rates; short-run supply was price-inelastic. Short-run price inelasticity could be a source for high volatility in oil and gas prices, and could confer to producers a temporary market power. Being simultaneous and incorporating interest and exchange rates, the model could be useful in short-term forecasting of oil and gas outputs and prices under policy scenarios.

Study of the Effect of Centrifugal Force on Rotor Blade Icing Process

In view of the rotor icing problems, the influence of centrifugal force on rotor blade icing is investigated. A numerical simulation method of three-dimensional rotor blade icing is presented. Body-fitted grids around the rotor blade are generated using overlapping grid technology and rotor flow field characteristics are obtained by solving N-S equations. According to Eulerian two-phase flow, the droplet trajectories are calculated and droplet impingement characteristics are obtained. The mass and energy conservation equations of ice accretion model are established and a new calculation method of runback water mass based on shear stress and centrifugal force is proposed to simulate water flow and ice shape. The calculation results are compared with available experimental results in order to verify the correctness of the numerical simulation method. The influence of centrifugal force on rotor icing is calculated. The results show that the flow direction and distribution of liquid water on rotor surfaces change under the action of centrifugal force, which lead to the increasing of icing at the stagnation point and the decreasing of icing on both frozen limitations.
Transitional failure of carbon nanotube systems under a combination of tension and torsion

Transitional failure envelopes of single- and double-walled carbon nanotubes under combined tension-torsion are predicted using classical molecular dynamics simulations. The observations reveal that while the tensile failure load decreases with combined torsion, the torsional buckling moment increases with combined tension. As a result, the failure envelopes under combined tension-torsion are definitely different from those under pure tension or torsion. In such combined loading, there is a multitude of failure modes (tensile failure and torsional buckling), and the failure consequently exhibits the feature of transitional failure envelopes. In addition, the safe region of double-walled carbon nanotubes is significantly larger than that of single-walled carbon nanotubes due to the differences in the onset of torsional buckling.
Does egg production represent adult female copepod growth? A call to account for body weight changes

An almost universal assumption in determining growth in copepods is that, over short periods, an individual adult female's net growth is equal to the amount of material expelled as eggs. This assumption relies upon adult body mass being in steady-state between the start and end of the same period. We explore different situations where this assumption is violated. Initially, concepts of how adult body weight and egg output are coupled over time are addressed. Using a refined concept of growth, we show that using typical 24 h incubation methods to measure egg output in sac spawn- ers or broadcasters that produce clutches of eggs with a periodicity of >1 d may give correct mean population growth rates, but erroneous individual rates (including maximum and minimum individ- ual growth, and measurements of individual variability such as coefficient of variation). Measure- ments derived from laboratory and field studies are then used to explore errors associated with the steady-state assumption. Decoupling of egg production from assimilation, and non-steady-state body weight in large lipid-storing higher-latitude species are relatively well documented, yet growth esti- mates allowing for such changes have almost never been made. Errors are not limited only to such species, however, and changing adult body weights can occur in small temperate and tropical species too. Body weight can increase or decrease whether or not eggs are exuded over the same period. The errors that can arise if we assume that the output of eggs by females equals their net growth rate are large and variable; in our compilation they range from -208% (i.e. egg output being 9.7% of body carbon weight per day, but adult carbon weight simultaneously declining by 13.7% d -1 ) to +71% (i.e. egg output being 1.5% of body carbon weight per day, and adult carbon weight simultaneously increasing by 4.3% d -1 ). Using measurement of the natural variability in adult body weights, we determined that in order to be able to discriminate significant changes in body weight of 1 and 10% respectively, >1000 and <100 replicates are necessary, if applying typical sacrificial weighing meth- ods. If we are to make accurate estimates of growth in adult copepods, then changes in body weight are of fundamental importance. We make initial recommendations for tackling these problems and reducing errors in the future
Bait attraction affects the performance of remote underwater video stations in assessment of demersal fish community structure

Discriminating marine fish assemblages at broad scales can be difficult because of het- erogeneity within their habitats, variability in patterns of behaviour and abundance of fish between habitats, and sampling biases in extractive fishing techniques when used across a range of habitats. Remote underwater video stations have recently been developed to help overcome these problems, but the use of bait as an attractant raises questions about bias towards scavengers and predators in samples of fish communities. We compared the ability of baited and unbaited underwater video sta- tions to discriminate between fish assemblages inhabiting distinct benthic habitats in temperate and tropical continental shelf waters in Australia, to help test whether the bait attracted predatory and scavenging species to the video in disproportionate numbers in comparison to other trophic groups, such as herbivores. Data from baited video cameras displayed a clearer discrimination in constrained canonical analysis of principal coordinates of fish assemblages between marine habitats in both trop- ical and temperate environments. Analysis of the key trophic groups indicated that bait attracted greater numbers of predatory and scavenging species without decreasing the abundances of herbiv- orous or omnivorous fishes. There was greater similarity between replicate samples from baited video within habitats, implying that the use of bait will provide better statistical power to detect spa- tial and temporal changes in the structure of fish assemblages and the relative abundances of indi- vidual species within them.
HYDROCARBONS AND BACTERIAL ACTIVITY IN MANGROVE SEDIMENTS FROM GUANABARA BAY, BRAZIL

In this study, a very extensive law protected mangrove area in the Eastern part of the Guanabara Bay was screened for petroleum hydrocarbons (PAHs) and bacterial activity. The aim was to understand the processes that control oil contamination in the mangrove sediments and if there is a relationship between this contamination and bacterial activity. Surface sediment samples were collected from 23 stations within the mangrove shoreline. The parameters pH, Eh, salinity and temperature were measured in situ. The sediments were immediately analyzed for bacterial activity, including: 1) electron transport system activity (ETSA); 2) activity of the esterase enzyme (EST); and 3) bacterial biomass. Analyses of the total PAHs contents were performed by UV-visible spectrofluorescence, total organic carbon was analyzed by titration and total phosphorus was analyzed by photocolorimetry, after wet oxidation. The results show that, in spite of the significant amounts of hydrocarbons loaded into the bay, Guapimirim mangrove still presents low concentrations. The presence of elevated concentrations of organic matter and nutrients provides sufficient energy for the development of an important bacterial biomass. The quality of the organic matter is determining the activity of the bacteria as indicated by ETSA and EST. When the organic matter is easily metabolized there would be predominance of esterase enzyme. The ETSA seems to be active most of the time, because bacteria is using readly available organic matter an PAHs. The results indicated that although there is a significant supply of easily metabolized organic matter, bacteria obtain part of its energy from the refractive organic matter. It is suggested that during the degradation of refractive organic matter, some petroleum hydrocarbons are also degraded.

Abstract. In the treatment of human epidermal growth factor receptor 2 (HER2)-positive advanced gastric or gastroesophageal junction cancer, it has been reported that the combination of trastuzumab with capecitabine plus cisplatin, or with 5‐fluorouracil (5-FU) plus cisplatin, significantly increase

In the treatment of human epidermal growth factor receptor 2 (HER2)-positive advanced gastric or gastroesophageal junction cancer, it has been reported that the combination of trastuzumab with capecitabine plus cisplatin, or with 5‐fluorouracil (5-FU) plus cisplatin, significantly increased overall survival compared with chemotherapy alone (ToGA trial). In addition, adjuvant therapy with capecitabine plus oxaliplatin (XELOX) improved the survival of patients who received curative D2 gastrectomy (CLASSIC trial). However, the efficacy of the combination of trastuzumab with XELOX for patients with HER2-positive gastric cancer remains unknown. The aim of this study, was to investigate the efficacy of the combination of trastuzumab with XELOX in a HER2-positive human gastric cancer xenograft model. Combination treatment with these three agents (trastuzumab 20 mg/kg, capecitabine 359 mg/kg and oxaliplatin 10 mg/kg), was found to exhibit a significantly stronger antitumor activity in NCI-N87 xenografts compared with either trastuzumab or XELOX alone. In this model, treatment with trastuzumab alone or trastuzumab plus oxaliplatin enhanced the expression of thymidine phosphorylase (TP), a key enzyme in the generation of 5-FU from capecitabine in tumor tissues. In in vitro experiments, trastuzumab induced TP mRNA expression in NCI-N87 cells. In addition, NCI-N87 cells co-cultured with the natural killer (NK) cell line CD16(158V)/NK-92 exhibited increased expression of TP mRNA. When NCI-N87 cells were cultured with CD16(158V)/NK-92 cells in the presence of trastuzumab, the mRNA expression of cytokines reported to have the ability to induce TP was upregulated in tumor cells. Furthermore, a medium conditioned by CD16(158V)/NK-92 cells also upregulated the expression of TP mRNA in NCI-N87 cells. These results suggest that trastuzumab promotes TP expression, either by acting directly on NCI-N87 cells, or indirectly via a mechanism that includes trastuzumab-mediated interactions between NK and NCI-N87 cells. Therefore, the combination of trastuzumab with XELOX may be a potent therapy for HER2-positive gastric cancer.
Where the Rubber Meets the Road: Revising Promotion and Tenure Standards According to Boyer

If one acknowledges that scholarship comes in many shapes and forms, and if one agrees with Boyer's argument that it is time to reconsider scholarship in light of the role of faculty members within departments, colleges, and universities, the next logical step then is to see if Boyer's principles can be effectively applied in a university setting. At the 1995 NAPEHE conference, Boyer acknowledged that the next step, as indicated by the title of the Carnegie Foundation's forthcoming sequel Scholarship Assessed, is to identify ways to fairly and equitably evaluate faculty scholarship within the context of the professoriate in general, and in higher education institutions in particular. The authors argue the case for differential application of standards within and among universities, based upon the diversity of missions and goals. Following that, examples are given for how Boyer's classifications have been applied to promotion and tenure standards at one comprehensive land grant university in the midwest. A.
Best new product development and management practices in the Korean high-tech industry

This paper investigates critical factors affecting the likelihood of new product success and effective new product development (NPD) models for Korean high-tech firms. Empirical results suggest that successful projects differ from unsuccessful projects in project environment, skills and resources, project leadership, strategic fit, efficient NPD process, and effective product-positioning strategies. This study confirmed that efficient and effective new product development and management were important determinants of high-tech firms' competitive advantage. Furthermore, the findings of this study raised questions about some commonly held beliefs when compared with Western studies focusing on high-tech industries.
Country Adaptation in Neural Machine Transliteration of Person Names

We have developed a neural machine transliteration system that can transliterate person names in many countries into Japanese. This system is constructed by two-step training. First, a base model is trained on a large countryunknown person-name dataset. Then, country-specific models are constructed from the base model by applying transfer learning with a set of small country-spcific datasets. An experiment shows that our system outperforms the previous CRF-based system.
Determinants of Positive Word of Mouth in the Tunisian Tourism Sector

Our study aims to support a critical view on a large literature on relational fidelity. It seeks to demonstrate that, to understand the loyalty in the context of an experiential consumption, the analytical framework must be changed. It is beyond the simplistic view considering consumption as an instantaneous act and positions themselves within a more holistic approach with consumption as an experience for the consumer. We try to investigate to what extent the novelty, control and commitment help explain the strength of the relationship that could bind a consumer to the provider. We discuss and test the validity of a complex network of relationships breaking with the theoretical approaches. Then, we test, through an empirical study, the validity of the relationships identified in the literature in the context of a consumption experience of hotel services in North West Tunisia.
HOW THE BURABURI GRANITE (Dolpo-Western Nepal) WAS DISCOVERED THROUGH REMOTE SENSING ANALYSIS AND GROUND TRUTH

More than forty years ago Fuchs and Frank (1970) sp eculated the presence of a granitic body (Buraburi Granite – BG) with very uncertain boundaries between Dolpo and Mugu Ka rnali regions (Nepal), about ten kilometers western than Kanjiroba massif. In particular the authors interpreted it as he southern portion of the bigger Mugu granite wh ich is located further to the north. Until that time only Arita et al. (1984) hav e reported the presence of a large granite body emp laced into the both Higher Himalayan Crystallines (HHC-Samla Pass schist) and Tibetan Sedimentary Sequence (TSS-Dhaulagiri limest one) in the northeastern area of Dolpo region. Despite they have briefly discussed various granite rock facies (tourmaline granite with or without garnet, biotite granite and muscovite grani te), no one sample was analysed. Consequently in th e most recent official maps and papers, this granite disappeared and the M ugu granite was hence confined to the north of the Mugu Karnaly river (Harrison et al.,1999). Data from the Advanced Spaceborn Thermal Emission a nd Reflection Radiometer (ASTER) were used to loca te and study the BG which was afterward confirmed by a ground truth mission. We have performed a petrographic study on thin sect ions of the samples collected using both optical mi croscope and microprobe. Furthermore some rock samples was analy zed with a spectrophotometer in order to compare th e satellite with laboratory spectral signatures. In the following we will briefly describe the remot e sensing method that allowed us to rediscover and correctly mapping the BG. The work-flow started from the image raw data p rerocessing and followed with the spectral analy sis and comparison between field and laboratory data. All the study we re performed using a Geographic Information System (GIS) to visualize, interpret and map the images. The laboratory and ASTER spectral data show an unli near mixing between granite and lichens signatures . The mixed signature has been used as a proxy of the BG demon strati g its potential for mapping the intrusion c ontacts in the area.
