Checkley, Matthew and Anóñ Higón, D and Alles, C (2017) The Hasty Wisdom of the Mob: How Market Sentiment Predicts Stock Market

We explore the ability of sentiment metrics, extracted from micro-blogging sites, to predict stock markets. We also add ess se ti e ts’ p edi ti e ti e-horizons. The data o e logge s’ feeli gs about five major stocks. Taking independent bullish and bearish sentiment metrics, granular to two minute intervals, we model their ability to forecast stock price direction, volatility, and traded volume. We find evidence of a causal link from sentiments to stock price returns, volatility and volume. The predictive time-horizon is minutes, rather than hours or days. We argue that diverse and high volume sentiment is more predictive of price volatility and traded volume than nearconsensus is predictive of price direction. Causality is ephemeral. In this sense, the crowd is more a hasty mob than a source of wisdom.
Optimization of nitrogen through organic and inorganic sources for enhancing maize (Zea mays L.) productivity

A field study was conducted to optimize nitrogen through organic and inorganic sources for enhancing maize (Zea mays L.) productivity at Research Farm of Agronomy Department, Punjab Agricultural University, Ludhiana during kharif 2013. Soil of experimental field was slightly alkaline in reaction (pH 7.9), low in organic carbon (0.38%) and available nitrogen (181.3 kg/ha), high in available phosphorus (33.5 kg/ha) and medium in available potassium (147.5 kg/ha). Experiment was laid out in split plot design with four replications comprising three FYM levels (0, 15 and 20 t/ha) in main plots and five nitrogen levels 0, 75, 100, 125 and 150% of recommended dose (125 kg/ha) through inorganic fertilizer in sub plots. Significant improvement in crop growth characters viz. plant height, number of leaves, leaf area per plant, leaf area index and dry matter accumulation and yield attributes viz. cob length and diameter, number of grain rows per cob, number of grains per cob and 100-grain weight was observed with the application of FYM up to 15 t/ha and nitrogen up to 125% of recommended level. Crop attained reproductive stage earlier with the application of FYM and inorganic nitrogen but crop maturity was delayed thus, grain filling period was prolonged, which resulted in significant yield increase. Grain yield increased by 23.5% and 27.1% with the application of 15 and 20 t/ha FYM, respectively over control (no FYM) but increase was significant with application of 15 t/ha. The highest level of nitrogen (150% of recommended) though increased yield (62.4 q/ha) by 2.6% over 125% of recommended (60.8 q/ha), but the increase was non-significant. Protein content, NPK and micronutrient uptake by grain improved significantly due to application of FYM and inorganic nitrogen. Application of FYM @ 15 or 20 t/ha left significantly left higher available N and K in soil at harvest over control but increase in available P was significant only up to 15 t/ha FYM. An inverse relation was observed for micronutrient content, agronomic efficiency, partial factor productivity, nitrogen harvest index and available P and K in soil at maize harvest with increase in the rate of nitrogen through inorganic source. Application of 15 t/ha FYM and nitrogen level up to 125% of recommended through inorganic source fetched extra net returns of `11,121/ha over no FYM and `41,826/ha over no nitrogen through chemical source, respectively.
Poisson PI algebras

We study Poisson algebras satisfying polynomial identities. In particular, such algebras satisfy "customary"' identities (Farkas, 1998, 1999) Our main result is that the growth of the corresponding codimensions of a Poisson algebra with a nontrivial identity is exponential, with an integer exponent. We apply this result to prove that the tensor product of Poisson PI algebras is a PI-algebra. We also determine the growth of the Poisson-Grassmann algebra and of the Hamiltonian algebras.
Global properties of ‘ordinary’ early-type galaxies: photometry and spectroscopy of stars and globular clusters in NGC 4494

We present a comprehensive analysis of the spatial, kinematic, and chemical properties of stars and globular clusters (GCs) in the ‘ordinary’ elliptical galaxy NGC 4494 using data from the Keck and Subaru telescopes. We derive galaxy surface brightness and colour profiles out to large galactocentric radii. We compare the latter to metallicities derived using the near-infrared Calcium Triplet. We obtain stellar kinematics out to � 3.5 effective radii. The latter appear flattened or elongated beyond � 1.8 effective radii in contrast to the relatively round photometric isophotes. In fact, NGC 4494 may be a flattened galaxy, possibly even an S0, seen at an inclination of � 45 degrees. We publish a catalogue of 431 GC candidates brighter than i0 = 24 based on the photometry, of which 109 are confirmed spectroscopically and 54 have measured spectroscopic metallicities. We also report the discovery of 3 spectroscopically confirmed ultra-compact dwarfs around NGC 4494 with measured metallicities of 0.4 . [Fe/H] . 0.3. Based on their properties, we conclude that they are simply bright GCs. The metal-poor globular clusters are found to be rotating with similar amplitude as the galaxy stars, while the metal-rich globular clusters show marginal rotation. We supplement our analysis with available literature data and results. Using model predictions of galaxy formation, and a suite of merger simulations, we find that many of the observational properties of NGC 4494 may be explained by formation in a relatively recent gas-rich major merger. Complete studies of individual galaxies incorporating a range of observational avenues and methods such as the one presented here will be an invaluable tool for constraining the fine details of galaxy formation models, especially at large galactocentric radii.
The Association between Calving Interval and Milk Production traits in population of dairy cows of Slovak Simmental cattle

The aim this work was to associations between calving interval and milk production traits in population of dairy cows of Slovak Simmental cattle in the period 2003-2009. The basic statistic analysis were analysed using the SAS version 9.1. 3. The average length between calving intervals was 413.34 days in population of dairy cows of Slovak Simmental cattle. Correlation between evaluated calving interval and traits of milk production (milk, fat, proteins) were lower negative r=-0.00924, r=-0.00539, r=-0.02381and correlation between calving interval and proteins in kg statistically high significant (P<.0001). The analyses by the effect on calving interval was the highest effect of herd-years-season R 2 = 0.212786, others effects of father R 2 = 0.028230 and cods of milk groups R 2 = 0.001353.

Effect of Purposeful Feature Extraction in High-dimensional Kinship Verification Problem

Recently, researchers have shown an increased interest in kinship verification via facial images in the field of computer vision. The matter of fact is that kinship verification is done according to similarities of parent and child faces. To this end, we need more local features extraction. All the methods reviewed so far, however, suffer the fact that they have divided images into distinct block, to extract more local features. The main problem has two aspects: aimless division and features extraction from unnecessary regions that lead to overlapping, noise and reduction of classification rate. In this paper, at first, the main parts of face such as eyes, nose and mouth are detected along with the whole face image. Then they will be used for feature extraction. In order to reduce feature vectors redundancy, new method of feature selection named as Kinship Feature Selection (KinFS), based on Random Subset Feature Selection (RSFS) algorithm is proposed. This method reduces the redundancy and improves verification rate by selecting effective features. The experiment results show that purposeful feature extraction by proposed KinFS method are efficient in improving kinship verification rate.
The Role of Affect in the Control of Attention to Monoracial and Racially Ambiguous Faces

Studies have shown that contextual factors can influence the person perception process and social categorization process (MacLin & Malpass, 2001; Ito et al., 2011; Newton, Dickter, & Gyurovski, 2011; Bartholow & Dickter, 2008). Contextual factors such as emotional affect and the race of surrounding individuals influence the way in which monoracial and racially ambiguous faces are perceived, which can subsequently affect judgments and behaviors (Bartholow & Dickter, 2008; Hugenberg & Bodenhausen, 2004). Much research has focused on the role of contextual factors in the perception of monoracial individuals (e.g. Bartholow & Dickter, 2008); however, research is lacking on the categorization of racially ambiguous individuals and how perceivers may use available contextual information to help reduce ambiguity and facilitate categorization. To examine the role of contextual factors in the perception and categorization of monoracial and racially ambiguous individuals, two studies were conducted in which White college students completed a modified flanker paradigm with Black, White, and racially ambiguous target faces displaying either a neutral, happy, or angry facial expression surrounded by flanker faces that displayed either congruent or incongruent race and affect. Results from Study 1 and Study 2 indicated that participants demonstrated an attentional bias to both Black faces and angry faces, regardless of compatibility with the target face. These findings suggest that because Black faces and angry faces both represent threatening or unfamiliar stimuli they may capture White perceivers' attention.
Seeking Social Equity in National Parks: Experiments with Evaluation in Canada and South Africa

Many national parks (NPs) and protected areas (PAs) worldwide are operating under difficult social and political conditions, including poor and often unjust relations with local communities. Multiple initiatives have emerged as a result, including co-management regimes and an increased emphasis on the involve­ment of indigenous people in management and conservation strategies more broadly. Yet, controversy over what constitutes an appropriate role for local people persists, and little research has been conducted as yet to systematically evaluate the extent to which NPs are socially (and not just ecologically) effective. This paper discusses a first attempt to examine the efficacy with which NPs address social equity, includ­ing property and human rights, and the relationship of indigenous people and NP managers. The results from an evaluation of equity in a purposive sample of six NPs in Canada and South Africa are presented. All but one of the case study NPs is found to be achieving or moving towards equity. In particular, NPs with more comprehensive co-management and support from neighbouring indigenous groups demonstrate higher equity scores across a variety of indicators, whereas NPs with lower levels of co-management do less well. NPs with settled land claims have not necessarily been more equitable overall, and a few NPs have been co-managed in name only.
RESPONSE OF LEPTIN AND C-REACTIVE PROTEIN SERUM LEVELS TO 12 WEEKS MODERATE INTENSITY AEROBIC EXERCISE IN OBESE MEN

The aim of this study was to investigate the effect of 12 weeks moderate intensity aerobic exercise on leptin and C-reactive protein serum levels in obese men. The study was conducted in Urmia- Iran in 2015. Twenty-four obese men with an aged range 40-50 yrs. were enrolled into the study. Subjects were randomized to one of 2 groups exercise (n=12) and control groups (n=12). The exercise group performed aerobic exercise training up to 50-70 % heart rate reserve, three times a week for 12 weeks. Leptin and CRP serum level was measured by ELISA method before and after the 12 weeks. After 12 weeks exercise training, leptin and CRP serum level in the exercise group compared to the control group, were decreased significantly ( P <0.05). To sum up, 12 weeks moderate intensity aerobic exercise in the reduction of CRP and leptin concentration had a prominent role that might be effective in reducing weight and improving cardiovascular risk factors.
Eukaryotic translation initiation factor 5A of wheat: Identification, phylogeny and expression

In the present study, we report on the characterization of a full-length cDNA clone (TaeIF5A-1) and as well as two genomic sequences (TaeIF5A-2 and TaeIF5A-3) encoding eIF5A in wheat (Triticum aestivum). In addition, 9 partial DNA sequences of eIF5A gene were also isolated from different species of triticeae tribe. Phylogenetic analysis of eIF5A coding genes in general revealed that TaeIF5A-1 represents ancestral types of the gene family in plant. Chromosome location analysis shows that TaeIF5A-2 was located on the chromosome 2BL. The mRNA level of TaeIF5A-1 has spatial and temporal difference, indicating it mainly plays important role in leaf development.
The effect of oral corrective feedback on enhancing second language vocabulary learning in Iranian EFL context

This research examines how adults learn L2 vocabulary when affected by different types of oral corrective feedback during a controlled classroom interaction. In addition, this study does not only focus on comparing the effectiveness of a particular type of corrective feedback versus another type, but also presents a penetrating examination of CF effects on L2 development in a multi-dimensional way. The quasi-experimental study used pretest-treatment-posttest design. Sixty male and female students learning English at intermediate level in Zabankade English language institute in Gorgan were the participants of this study. They were divided into three groups including prompt, recast, and control group. In the treatment stage, a four-step vocabulary activity was provided to prompt, recast or no feedback group, respectively. Pair-sample t-tests and ANOVA were used for data analysis. The results of the study indicated that using prompts and recasts as two kinds of oral corrective feedback were of benefit to students in terms of their ability to detect and correct errors in their own speech when they are learning new vocabularies. It is hoped that the findings of this study will shed some light on blurred issues of recast and prompt as two kinds of providing oral corrective feedback and their impact on enhancing vocabulary learning performance.
Which Investors Fear Expropriation? Evidence from Investors' Stock Picking

Using a data-set that provides unprecedented details on individual investors’ stockholdings, we analyse whether investors take into account corporate governance when they select stocks. After controlling for the supply effect via free float and other firm characteristics, we find that all categories of investors who generally enjoy only security benefits (domestic and foreign; institutional and small individual investors) are reluctant to invest in companies with bag corporate governance. In contrast, individuals who have strong connections with the local financial community because they are board members or hold large blocks of at least some listed companies behave differently. They do not care about the expected extraction of private benefits or even prefer to invest in firms where there is more room for it. Overall, the effect of corporate governance on portfolio decisions is more pronounced for small and medium size companies. These findings shed new light on the determinants of investor behaviour, and suggest that it is important to distinguish between investors who enjoy private benefits or access private information and investors who enjoy only security benefits in order to understand portfolio choices.
02 APPLICATION OF QUANTILE REGRESSION TO ASYMMETRIC PRICE TRANSMISSION ESTIMATION : INSIGHTS FROM MONTE CARLO SIMULATIONS

Paper introduces and compares performances of Quantile regression approach to the conventional Ordinary Least Squares methods for estimation of asymmetric price transmission model when the true data generating process is known. Monte Carlo simulation results indicate that the estimates of the coefficients of the asymmetric price transmission model derived from the Least squares and the Quantile regression approaches are accurate and equivalent or close to their true values for normal data regardless of variability in sample size. Least squares method is affected by outliers and yields inaccurate estimates of the coefficients of the asymmetric price transmission model across various sample sizes when the data contains outliers. Quantile regression estimation remains robust to outliers in large samples and provides estimates of the coefficients of the asymmetric price transmission model that are accurate and nearly equivalent to their true values. The evidence from Monte Carlo experimentation suggests that the proposed Quantile regression estimation is likely to do no worse than the OLS with normal dataset and promise to do better when the dataset has outliers within the asymmetric price transmission modelling context.
Phytochemical and Antibacterial Properties of Calotropis Procera (Ait) R. Br. (Sodom Apple) Fruit and Bark Extracts

Phytochemical and antibacterial activities of water, methanol and ethanol extracts obtained from the fruit and bark of Calotropis procera were investigated in an attempt to evaluate its medicinal potentials. The phytochemical screen- ing revealed the presence of alkaloids, flavonoids, tannins, saponins, and cardiac glycosides with a very high content in water extracts. The concentration of the phytochemical constituents were in the order of water > methanol > ethanol. Anti- bacterial activity was determined against Pseudomonas aeruginosa, Salmonella typhi, Escherichia coli and Streptococcus pyrogenes. Water extracts showed inhibition against the tested organisms at 30 mg/ml. Methanol and ethanol extracts did not show an appreciable activity at 30 and 90 mg/ml respectively. The result of this study validates the use of water extract of this species in ethnomedicine and could provide a lead in the isolation of antibacterial agents from water extracts of Calotropis procera.
Examining death loss in Kansas feedlots

This study had three primary objectives: 1) to determine if there is an annual and/or seasonal trend in percentage of death loss in Kansas feedlots; 2) to examine the difference in death loss between steers and heifers; and 3) to evaluate if “in” weight has had an effect on percentage of death loss in Kansas feedlots. The annual trend in death loss for both steers and heifers was found to be significant and positive, indicating that death loss has been increasing over the sample period. Seasonal increases in death loss were significant for early-spring closeouts for both steers and heifers. The annual trend in the difference between the death loss for steers and heifers, though not significant, was negative. There were, however, certain closeout months in which there were significant differences in the death loss of steers relative to heifers. Placement weight had a significant negative impact on death loss in heifer finishing, but no significant impact on steer finishing. Our regression analysis indicates that death loss has been increasing over the sample period, that certain closeout months tend to impact steer and heifer death loss differently, and that placement weight in heifers has had a significant impact on percentage of death loss in cattle.
Borcherds Products on Unitary Group $U(2,1)$

In this note, we construct canonical bases for the spaces of weakly holomorphic modular forms with poles supported at the cusp $\infty$ for $\Gamma_{0}(4)$ of integral weight $k$ for $k\leq-1$, and we make use of the basis elements for the case $k=-1$ to construct explicit Borcherds products on unitary group $U(2,1)$.
Varieties of group representations and Casson’s invariant for rational homology 3-spheres

Andrew Casson's Z-valued invariant for Z-homology 3-spheres is shown to extend to a Q-valued invariant for Q-homology 3-spheres which is additive with respect to connected sums. We analyze conditions under which the set of abelian SL2(C) and SU(2) representations of a finitely generated group is isolated. A formula for the dimension of the Zariski tangent space to an abelian SL2(C) or SU(2) representation is obtained. We also derive a sum theorem for Casson's invariant with respect to toroidal splittings of a Z-homology 3-sphere. Andrew Casson's lectures at MSRI in the spring of 1985 introduced an integer valued invariant of oriented integral homology 3-spheres. This invariant, constructed by means of representation spaces, yields interesting new results in low dimensional topology. In this paper we examine the extent to which Casson's procedure for defining his invariant can be used to obtain a rational valued invariant for oriented rational homology 3-spheres. Let 7r be a finitely generated group and G a Lie group. It is well known that the set R(7, G) of all homomorphisms of 7r into G can be given the structure of an analytic set in a natural manner. If G is an algebraic group, R(7r, G) becomes an algebraic set. The closed subspace of R(7r, G) consisting of representations 7r -* G with abelian image will be denoted by A(7r, G) . Let Rn(7,, G) be the union of those components of R(7r, G) which do not meet A(7r, G). When G is understood from the context, it will be dropped from the notation. If R is a commutative ring, an R-homology 3-sphere is a closed, orientable (over Z) 3-manifold with homology isomorphic to H*(S3; R). Let H(R) be the set of oriented homeomorphism types of oriented R-homology 3-spheres. For M E 11(Z) Casson defined an integer valued invariant A(M). We briefly recall his definition (see [AM] for a comprehensive exposition of Casson's MSRI lectures). Let M = WI UF W2 be a Heegard decomposition of M, where F = & W is of genus g and let F* be F punctured once.
