Network structure detection and analysis of Shanghai stock market

Purpose: In order to investigate community structure of the component stocks of SSE (Shanghai Stock Exchange) 180-index, a stock correlation network is built to find the intra-community and inter-community relationship. Design/methodology/approach: The stock correlation network is built taking the vertices as stocks and edges as correlation coefficients of logarithm returns of stock price. It is built as undirected weighted at first. GN algorithm is selected to detect community structure after transferring the network into un-weighted with different thresholds. Findings: The result of the network community structure analysis shows that the stock market has obvious industrial characteristics. Most of the stocks in the same industry or in the same supply chain are assigned to the same community. The correlation of the internal stock prices’ fluctuation is closer than in different communities. The result of community structure detection also reflects correlations among different industries. Originality/value: Based on the analysis of the community structure in Shanghai stock market, the result reflects some industrial characteristics, which has reference value to relationship among industries or sub-sectors of listed companies.
High-dimensional neural-network potentials for multicomponent systems: Applications to zinc oxide

Artificial neural networks represent an accurate and efficient tool to construct high-dimensional potentialenergy surfaces based on first-principles data. However, so far the main drawback of this method has been the limitation to a single atomic species. We present a generalization to compounds of arbitrary chemical composition, which now enables simulations of a wide range of systems containing large numbers of atoms. The required incorporation of long-range interactions is achieved by combining the numerical accuracy of neural networks with an electrostatic term based on environment-dependent charges. Using zinc oxide as a benchmark system we show that the neural network potential-energy surface is in excellent agreement with density-functional theory reference calculations, while the evaluation is many orders of magnitude faster.
The Role of Cancer-Associated Fibroblasts in Lung Tumorigenesis

The extracellular milieu is rich in growth factors that drive tumor progression, but the mechanisms that govern tumor cell sensitivity to those ligands have not been fully defined. In this study, we address this question in mice that develop metastatic lung adenocarcinomas through the suppression of the microRNA200 (miR-200) family. Cancer-associated fibroblasts (CAF) enhance tumor growth and invasion by secreting VEGF-A that binds to VEGFR1, a process required for tumor growth and metastasis in mice and correlated with a poor prognosis in lung adenocarcinoma patients. In this study, we discovered that miR-200 blocked CAF-induced tumor cell invasion by directly targeting VEGFR1 in tumor cells. In the context of previous studies, our findings suggest that the miR-200 family is a point of convergence for diverse biologic processes that regulate tumor cell proliferation, invasion, and metastasis; its target genes
Potential use of clay from Burkina Faso as filler in rubber production

raw clay materials deposit in Burkina Faso have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and chemical analysis to evaluate their potentialities to be used in rubber compounds production as filler. The samples are composed principally by aolinite, illite and quartz. The rubber compounds have been done in open two-roll mill at room temperature and tested for cure characteristic (t s 5, t c 90), ineralogical composition by XRD, microstructure by SEM and mechanical properties (Elongation at break, Tear strength, tensile strength, hardness shore A and modulus). The cure characteristics of the rubber compounds formulated with the sample are feeble than those made with commercial kaolin (control). The mechanical properties are in general, except the longation at break, for the sample lowest than those of control. However the different values obtained with the sample are not far to those obtained with commercial kaolin. The different samples can then be used as filler in rubber production after a pre-treatment to reduce the impurities. Keywords : Raw clay materials, rubber, rheology.
Possibilities of Applying Hydrological Methods for Determining Environmental Flows in Select Catchments of the Upper Dunajec Basin

Our paper describes a method for determining environmental flows based on the use of the Tennant and Tessman methods – based on flow duration curves – as well as instream flows using the methods of Kostrzewa, the National Foundation for Environmental Protection and Water Management, and the Malopolska method. Calculations were conducted for the catchments of three rivers: the Ochotnica, the Wielki Rogoznik, and the Mlyniska – all located in the basin of the Upper Dunajec. Input data obtained from the Institute of Meteorology and Water Management, the National Research Institute, were observation series of daily flows for the years 2000-09. The hydrometric data were evaluated in terms of homogeneity and independence using the Mann-Kendall-Sneyers test. The following characteristic flows were determined: minimum flow, mean annual low flow, and mean annual flow. The authors were inspired to perform this analysis by Polish regulations requiring that the instream flow refers to needs of aquatic ecosystem organisms, but they do not take into account the needs of waterdependent ecosystems (wetlands). Therefore, we assessed the possibilities of applying hydrological methods to determine the environmental flow, taking into account the needs of both aquatic ecosystems and floodplains. The calculations revealed differences between the values of the instream and environmental flows and also allowed us to conclude that in all the analyzed catchments the computed instream and environmental flows were below the level determined by the average monthly flow. Based on the indicated ecological criterion, the Tessman method was recommended to determine environmental flow in the Upper Dunajec basin, but emphasizing that adaptation of methods should be carried out to calculate environmental flow, which will take into account physiographic, climatic, and natural conditions of studied basins.
Core Stabilization Exercise and Movement System Impairment Approaches for Patients with Movement Control Impairment: A Review Article

Treatment-based and movement system impairment-based classifications have been widely used to identify movement control impairment (MCI) in patients with non-specific low back pain. Clinical observation of aberrant movement patterns is an essential aspect of the examination to identify patients with MCI. The treatment of these patients is a therapeutic exercise that involves static and dynamic stability of core stabilizing muscles. Although exercise prescriptions for these patients are similar, intervention may vary based upon its concept. Interventions include the core stabilization exercise (CSE) approach based upon stabilizing system model, and movement system impairment (MSI) approach based upon kinesiopathologic model. CSE focuses on neuromuscular function to compensate for impairment of intervertebral disc and joints, whereas MSI emphasizes movement correction and enhances movement efficiency to prevent injury and impairment. Both approaches seem equally effective in reducing pain and disability for the MCI group. Therefore, clinicians can utilize either approach for rehabilitating patients with MCI. However, if differences in effectiveness are found when utilizing these different approaches we should explore if the MCI classification needs further definition. In addition, further study needs to investigate the underlying mechanisms in patients with MCI, and the ability of each approach to change those mechanisms.

Strategic Asset Allocation with Predictable Returns and Transaction Costs

We propose a factor-based model that incorporates common factor shocks for the security returns. Under these realistic factor dynamics, we solve for the dynamic trading policy in the class of linear policies analytically. Our model can accommodate stochastic volatility and liquidity as a function of same factor exposures. Calibrating our model with empirical data, we show that our trading policy achieves superior performance particularly in the presence of common factor shocks.
IMPLEMENTATION OF MEDIA INTERACTIVE LEARNING BASED WLAN TECHNOLOGY (STUDY AT SMK KAMPAR)

Information and communication technology in education is growing rapidly. Computer network technology, the Internet and multimedia strongly supports the development of education in distributing information quickly. However, some vocational schools have not fully utilised the potential of this technology to improve the quality of learning.The research objective is to study the implementation of interactive learning media physics based WLAN technology and to analyze the effectiveness of the learning media as a way to increase the motivation of students majoring in computer engineering at SMK YPTK and at SMK Bina Insan in Kampar regency. Qualityof service(QoS) assessment of the learning system implemented already reliable. The average assessment results of student satisfaction in the use of interactive learning media is good (75.15).

Spatial integration of rice markets: The case of Kwara and Niger States, Nigeria

This study examined whether rice markets in Kwara and Niger States, Nigeria are integrated or not. Secondary data of retail prices of rice were collected for a period of 60 months (2006-2010) and error correction technique was employed in the determination of the degree of market integration between the two States using a four test procedures viz: Augumented Dickey Fuller test to detect for the presence of unit root in the series; Johansen co-integration test for the long run equilibrium relationship among the variables; vector error correction model test (VECM) to capture short-run and long-run changes in the price movements; and Granger casualty test to reflect the direction of influence between prices. The overall analysis of the vector error correction estimates shows that most of the markets in the two states were not well integrated in the short run. In other words, price adjustment across markets did not happen instantaneously. It took some times for the spatial price adjustments to take place. However, the co-integration results revealed that most of the markets in the two states were well integrated in the long run in the study area. The causality test results indicated that though the two States rice markets drifted apart in the short run, there was smooth transmission of price signals and marketing information from Kwara State to Niger State rice markets.
When Labour and Capital Collude: The Varieties of Welfare Capitalism and Early Retirement in Europe, Japan and the USA. CES Germany & Europe Working Papers, No. 00.4, 2000

The institutionalisation of early retirement has become a universal feature of postwar industrial economies, though there are significant cross-national variations. This paper studies the impact of different types of welfare regimes, production systems and labour relations on early exit from work. After an analysis of the main trends, the paper discusses the costs and benefits of early retirement for the various actors — labour, capital and the state — at different levels. The paper outlines both the "pull” and "push” factors of early exit. It first compares the distinct welfare state regimes and private occupational pensions in their impact on early retirement. Then it looks at the labour-shedding strategies inherent to particular employment regimes, production systems and financial governance structures. Finally, the impact of particular industrial relations systems, and especially the role of unions is discussed. The paper finds intricate "institutional complementarities” between particular welfare states, production regimes and industrial relations systems, and these structure the incentives under which actors make decisions on work and retirement. The paper argues that the "collusion” between capital, labour and the state in pursuing early retirement is not merely following a labour-shedding strategy to ease mass unemployment, but also caused by the need for economic restructuration, the downsizing pressures from financial markets, the maintenance of peaceful labour relations, and the consequences of a seniority employment system.
Use of Expressive Arts to Improve Quality of Life in Individuals with Mental Illness

Within the mental health community, the expressive arts are gaining popularity as a respected form of therapy; however, there is still much to be discovered in regard to its effectiveness with individuals with a mental health diagnosis. Research completed to date includes the exploration of a variety of modalities and its benefits to those with a mental illness, but it lacks an examination of the effect that the expressive arts has on overall quality of life. As a contribution to what will hopefully be an expanding area of interest, this writer designed an expressive arts therapy group facilitated at a mental health day programming facility. The group was facilitated over ten weeks with participants ranging in age from 26 to 68. Results did not indicate a substantial change in quality of life scores; however, the participants’ consistent participation, themes of hope, passing time, and moving forward, and demonstration of trust amongst group members suggested that the expressive arts modalities benefit the quality of life of individuals living with a mental health condition.
J2.3 OVERVIEW OF CERES CLOUD PROPERTIES DERIVED FROM VIRS AND MODIS DATA

Simultaneous measurement of radiation and cloud fields on a global basis is recognized as a key component in understanding and modeling the interaction between clouds and radiation at the top of the atmosphere, at the surface, and within the atmosphere. The NASA Clouds and Earth’s Radiant Energy System (CERES) Project (Wielicki et al., 1998) began addressing this issue in 1998 with its first broadband shortwave and longwave scanner on the Tropical Rainfall Measuring Mission (TRMM). This was followed by the launch of two CERES scanners each on Terra and Aqua during late 1999 and early 2002, respectively. When combined, these satellites should provide the most comprehensive global characterization of clouds and radiation to date. Unfortunately, the TRMM scanner failed during late 1998. The Terra and Aqua scanners continue to operate, however, providing measurements at a minimum of 4 local times each day. CERES was designed to scan in tandem with highresolution imagers so that the cloud conditions could be evaluated for every CERES measurement. The cloud properties are essential for converting CERES radiances shortwave albedo and longwave fluxes needed to define the radiation budget (ERB). They are also needed to unravel the impact of clouds on the ERB. The 5-channel, 2-km Visible Infrared Scanner (VIRS) on the TRMM and the 36-channel 1-km Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra and Aqua are analyzed to define the cloud properties for each CERES footprint. To minimize inter-satellite differences and aid the development of useful climate-scale measurements, it was necessary to ensure that each satellite imager is calibrated in a fashion consistent with its counterpart on the other CERES satellites (Minnis et al., 2006) and that the algorithms are as similar as possible for all of the imagers. Thus, a set of cloud detection and retrieval algorithms were developed that could be applied to all three imagers utilizing as few channels as possible while producing stable and accurate cloud properties.
PATHOGENICITY OF Metarhizium anisopliae AGAINST Lipaphis

Seven native fungal isolates were obtained from soil collected from different field crops. Four procured isolates of Metarhizium anisopliae viz. Ma-NBAII-11, PDBC Ma-4, Ma-MTCC 3872, Ma-13 along with seven native fungal isolates were characterized on the basis of morphological characters viz. colony morphology, spore shape, spore size and conidial arrangement. Procured isolates of M. anisopliae showed white coloured colony when young and later turned into dark green or olive green. Spore size ranged from 2.5 to 5μm, septate and branched hyphae with condiophore terminating into a single or a cluster of phialides were present. Native fungal isolate F12 was identified as Metahizium sp. as they showed similar characterstics as that of Metarhizium. Fungal isolates F2, F5 and F13 were identified as Aspergillus spp. Further F6, F7 and F14 were identified as Penicillium spp. All these eleven fungal isolates along with six commercial formulations two each of Beauveria bassiana, M. anisopliae and Lecanicillium lecanii with untreated control were evaluated against nymphal stage of Lipaphis erysimi KALT. Among procured isolates, Ma-13 was most pathogenic which recorded 99.12 per cent cumulative mortality of nymphal aphid at higher concentration (10 9 conidia ml -1 ). Lowest LC50value (0.057x10 7 spores ml -1 , 0.005x10 7 spores ml -1 and 0.006x10 7 spores ml -1 ) were recorded in isolate Ma-13 after 72, 120 and 168 hrs which recorded high effectiveness against L. erysimi and caused maximum mean cumulative mortality (98.13%) when evaluated under laboratory condition. Among native fungal isolates, F12 showed maximum cumulative mortality (66.21%) which was followed by mortality (62.74%) in fungal F13. Further, commercial formulation L. lecanii I was most pathogenic and recorded maximum mortality (99.23, 98.07 and 97.11%) at doses 10, 9 and 8g/l which were at par with each other against nymph of L. erysimi and was potential formulation. Pathogenicity of four procured isolates of M. anisopliae was evaluated against aphid at different temperatures (15±1C, 20±1C, 25±1C and 30±1C) and maximum cumulative per cent mortality (93.58%) was recorded at temperature 25 C.
The Impact of Splitting Up and Divorce on Housing Careers in the UK

Using 1991–2004 data from the British Household Panel Survey (BHPS) this paper analyses the effect of union dissolution on the occurrence of moves, changes of dwelling type, and the probability of moving out of owner-occupation. The main contributions of this paper are that it takes into account the rise in the occurrence of cohabitation, by analysing the dissolution of cohabiting and marital unions separately, and that it studies the effect of re-partnering on housing careers. Using logistic regression models clear evidence was found that the dissolutions of marriage and cohabitation result in different housing career outcomes. In particular, those who divorce experience a larger drop in housing quality than do those who split up from cohabitation. Starting a new relationship leads to more upward moves in the housing career compared to remaining divorced or split up.
A Re-Evaluation of the Importance of Protein Kinases in the Responseof Arabidopsis Roots to Phosphate Starvation and Iron Deficiency

Phosphorus (P) and iron (Fe) are essential mineral nutrients for plant growth, and deficiencies in these elements alter many developmental programs. Our previous genome-wide co-expression analysis has predicted that protein kinase (PK) plays a key role in the regulation of phosphate (Pi) deficiencyinduced root hair remodeling in Arabidopsis. In this study, the RNA-seq data were re-mined to dissect the potential functions of PKs in Arabidopsis roots under Pi and Fe deficiency. Our results showed that 33 PKs were identified as changed expression at transcript level and a subset of 18 genes was detected with uniquely matched peptides at protein level. Some of the 18 corresponding proteins were found to be also involved in the responses to multiple abiotic stresses. The importance of PKs in the responses to nutritional stress was discussed.
RESPONSE OF PEPEROMIA OBTUSIFOLIA (L.) A. DIETR CV. VARIEGATA PLANT TO SOME FERTILIZATION TREATMENTS

Prof. Dr. M.M. Farahat, Agric. & Biol. Res. Div. , NRC. ABSTRACT: An experiment was established under plastic house at the nursery of Hort. Res. Inst. , ARC, Giza, Egypt during 2012 and 2013 seasons to find out the effect of foliar spraying with active dry yeast solution at 0, 1, 3 and 5 g/l, soil drenching with NPK mixture (2:2:1) at 2 g/pot and the interaction between each level of yeast and that of NPK mixture on growth and chemical composition of 3months-old transplants of Peperomia obtusifolia (L.) A. Diter. grown in 14-cm-diameter plastic pots filled with about 1 kg of an equal mixture of washed sand, clay and peatmoss (1:1:1, by volume.) The obtained results indicated that various single and combined treatments improved all vegetative and root growth parameters with various significant differences compared to the control in both seasons. Active dry yeast alone at 3 g/l treatment gave better result than the other individual ones, whereas comparing between any level of dry yeast combined with NPK (2 g/pot) was more effective in improving vegetative and root growth of plants than all the individual treatments, the interaction between 3 g/l active dry yeast and 2 g/pot NPK recorded the best growth at all in both seasons. On the same line were those results of pigments content in the leaves reached maximum by 3 g/l dry yeast, but the opposite was right regarding the percentages of total soluble sugars, N, P and K content those reached the highest values by the level of 5 g/l dry yeast in most cases of both seasons. However, content of those constituents was doubled by connecting between active dry yeast at any level and NPK mixture 2 g/pot, with the prevalence of 3 g/l active dry yeast plus 2 g/pot NPK combination, that gave the highest content in the two seasons. Hence, it can be recommended to fertilize Peperomia obtusifolia cv. Variegata plants cultivated in 14-cm-diameter plastic pots with active dry yeast at 3 g/l (as a foliar spray) plus NPK mixture (2:2:1) at 2 g/pot (as a soil drench), 5 times with one month interval to obtain the best vegetative growth and high pot plant quality.
