AN EXPRESSION FOR THE RADAR CROSS SECTION COMPUTATION OF AN ELECTRICALLY LARGE PERFECT CONDUCTING CYLINDER LOCATED OVER A DIELECTRIC HALF-SPACE

A method is presented to calculate the monostatic Radar Cross Section (RCS) of an electrically large perfect conducting cylinder vertically located over a dielectric half-space using Physical Optics (PO) technique. The four-path modal method is used to approximate the influence of the half-space to the scattering mechanism. The comparison between the results calculated by this expression and that by Moment Method (MOM) show that the expression is effective and efficient.
Stocks’ pricing dynamics and behavioral finance: A review

Article history: Received March 25, 2015 Received in revised format June 1 2015 Accepted June 27 2015 Available online July 1 2015 In a brief review of the literature on stocks’ pricing, the study shows that information vis-a-vis noise serves critical roles in the equilibrium process. It is dynamic in nature and there are different infiltrating aspects from the standard finance to behavioral finance points of views. The aspects of market efficiency, fundamental risk, noise traders’ risk, and implementation costs make the stock markets noisy and thereby, limit the arbitrage opportunity of informed traders. Investors’ psychological bases viz., belief and preferences contribute more in the equilibrium process. Beliefs include representativeness, conservativeness, and anchoring, availability biases, optimism and wishful thinking, overconfidence, and herd behavior tendency on the part of the investors. On the preferences, investors are influenced by disposition effect, prospects based on reference points, mental accounting, ambiguity aversion, and self control.The study explores the empirical literature also and reviews the six puzzles in the standard finance. Finally, the work identifies a few research gaps to be addressed in the literature.
THE ROLE OF CORPORATE SOCIAL RESPONSIBILITY DISCLOSURE TOWARD COMPANY STOCK PRICE CRASH RISK

This study aims to analyze the influence of corporate social responsibility disclosure to company stock price crash risk. If socially responsible companies are committed to high standards of information transparency and do not hide bad news, they will have a low risk of crash. However, if the manager reports CSR to distract the stakeholder from bad news, the CSR will be associated with a high risk of the company stock crash. The study was conducted at Indonesian manufacturing companies registered on the IDX (BEI) for the 2010-2015 period Hypothesis testing technique used a multiple regression analysis. The results showed that activities of the corporate social responsibility disclosure by the company did not have a significant relationship to the risk of the company stock price crash. This study also found that companies that conduct and report social responsibility activities simultaneously have a low risk of crashes on their company's stock price but cannot prove the relationship between the two. The implication is that social accountability reports in Indonesia are still limited to reports only and have not been considered as anything that can contribute to add value to the company or that may prevent the company from unethical behavior.
BITUMEN COATING FOR DOWNDRAG MITIGATION IN COHESIONLESS SOILS

Effectiveness of bitumen coating in mitigating downdrag in cohesionless soils was investigated using direct shear apparatus and a rod shear test. Tests on soft and stiff bitumen sheared with sand and crushed limestone showed that changes in temperature, shear-strain rate, and normal stress significantly affected the shearing characteristics of bitumen coating. Increasing the normal stresses caused an increase in the soil-particle penetration layer into the bitumen and altered the viscous behavior of the material. High friction resistance was recorded when crushed limestone was used to shear the bitumen layers. Stiff bitumen coating provided better protection against soil penetration than soft bitumen. However, at high temperatures, both bitumens lost their protective capabilities, resulting in a significant soil penetration into the bitumen coating. Bitumen-coated samples tested with sand exhibited the lowest friction. The effectiveness of bitumen coating in this case was 98%; it dropped to 54% when crushed limestone was used.
Enzymatic modification and antioxidant activity of russula alutacea polysaccharides

This paper aims to explore the effect of enzymatic modification on the antioxidant activity of Russula alutacea (R. alutacea) polysaccharides. To this end, the polysaccharides were extracted by water and precipitated by alcohol, and subjected to enzymatic modification. Then, the hydroxyl radicals, superoxide anions, DPPH radicals scavenging rates and reducing power were used to determine and compare the properties of the modified and unmodified R. alutacea polysaccharides. The results show that the polysaccharide content of the sample was 1.92%; the ability to scavenge hydroxyl radicals, superoxide anions and DPPH radicals increased with the concentration; the modified polysaccharides had higher scavenging rates than the unmodified polysaccharides, but the rates were similar at the same concentration; the free radicals scavenging rate of the modified polysaccharides was slower than that of ascorbic acid; in terms of the reducing power, the modified polysaccharides was stronger than unmodified polysaccharides, but far weaker than ascorbic acid.
Wheat production using direct seeding and conventional tillage in Middle Anatolia.

The objective of this study was to examine wheat production using direct seeding and conventional tillage in Middle Anatolia during the years of 2006-2007 and 2007-2008. In the experiment, conventional tillage and the direct seeding were used. Tillage and the direct seeding were applied in the dry farming conditions. The effect of treatments on mean emergence dates, percentage of emerged seedling, fuel consumptions and wheat yield were measured. The highest fuel consumption was measured in the conventional method as 46.1 l ha-1 whereas the lowest value was found in the direct seeding method as 10.7 l ha-1. Fuel consumption of the conventional method required four times more fuel than the direct seeding method. The best result for wheat yield was found in the direct seeding as 3388.9 kg ha-1 in 2008. The lowest wheat yield was found in the conventional method as 2290 kg ha-1 in 2007. The direct seeding gives the best result for fuel consumption and wheat yield. In the dry farming condition, the direct seeding methods can be proposed for wheat production in the Middle Anatolia.
The information dynamics of melodic boundary detection

published models of perceived grouping structure in music are inspired by Gestalt psychology, associating grouping boundaries with discontinuities or changes in various dimensions of the musical surface. We examine a complementary approach based on information dynamics in melody perception according to which boundaries are perceived at points of expectancy violation and predictive uncertainty. We discuss empirical evidence for and against the two theories, consider how they relate to one another and suggest methods for further empirical investigation and development of the information dynamics approach.
Inclusion of Sex Education in School Curriculum of Bangladesh: Parents’ Attitude

The study examined the attitude of Bangladeshi parents’ regarding inclusion of sex education in school curriculum of Bangladesh. Using 21 topics of comprehensive sex education, parents were asked to explore which topics they believed should be taught in schools. The study also assessed the relationship between the parents’ demographic characteristics (residence, sexual orientation, religious belief, occupation, and educational background) and their attitude towards sex education. The study found that 48.3% parents support sex education whilst 25% parents did not support sex education and rests were found neutral position among 120 sampling size. Most of the parents supported the topics of sex education which were mostly value and culture oriented instead of the knowledge of sexual intercourse, abortion, taking protection for premarital sexual activity etc. Moreover, form Chi-square test the study found that there had significance difference between the attitude of parents towards inclusion of sex education and their residence, occupation or educational background.
Human Intelligence in Federal Terrorism Cases

Though it has often been quipped that the September 11 attacks changed “everything”, domestic policy alterations were among the most significant changes after 9/11. Specifically, the 2002 Ashcroft Attorney General Guidelines and the 2008 Mukasey Attorney General Guidelines were two of the most impactful policy changes following 9/11. These Attorney General Guidelines changed the way the Federal Bureau of Investigation (FBI) investigated terrorism in the United States in addition to making counterterrorism the FBI’s top priority. One of the ways the FBI prevents terrorism is through the use of undercover agents and confidential informants. How the 2002 and 2008 Attorney General Guidelines influenced the FBI’s use of human intelligence in terrorism investigations has remained to be seen. This study reviews the historical policy changes following 9/11 and examines their influence on the FBI’s use of undercover operatives in terrorism cases. While I found that the percentage of terrorism investigations that used undercover operatives dropped by over 40% after the Ashcroft Guidelines were implemented, I also found that investigations that used undercover operatives were more successful in preventing terrorism incidents compared to terrorism investigations that did not use undercover operatives. Thus, policy makers should use caution when amending guidelines to terrorism investigations and perhaps a lot more resources to undercover operations.

The imbalance of paleontological trees

Abstract One of the most extensively studied aspects of phylogenetic tree shape is balance, which is the extent to which nodes divide a tree into clades of equal size. Several authors have stressed the importance of tree balance for understanding patterns of evolution. It has been remarked that paleontological studies commonly produce very unbalanced trees (also called pectinate cladograms or “Hennigian combs”). This claim is tested here by comparing the balance of 50 paleontological trees and 50 neontological trees, all taken from the recent literature. Each tree was reanalyzed from the published data matrix to ensure its accuracy. The results confirm that paleontological trees tend to be more imbalanced than neontological trees. That paleontological trees are more imbalanced has been represented as a shortcoming of fossil data sets, but here it is argued that this is the expected result. Even under a simple Markovian model in which all speciations and extinctions occur randomly and with equal probability in all parts of the tree, trees based on taxa from a single time period (e.g., the present day) are generally more balanced than trees based on all taxa that ever existed within the clade. Computer simulation is used to calculate the expected balance and standard deviation of trees for up to 40 terminal taxa over the entire history of a model clade. The balance is measured using Colless's index, Ic, and the expected balance conforms well with published paleontological trees. The study underlines the difficulty of applying neontological tree statistics in paleontology.
The Spectroscopic Binaries 21 Her and Gamma Geminorum

In the framework of a search campaign for short-term oscillations of early-type stars we analysed recently obtained spectroscopic and photometric observations of the early A-type spectroscopic binaries 21 Her and Gem. From the radial velocities of 21 Her we derived an improved orbital period and a distinctly smaller eccentricity in comparison with the values known up to now. Moreover, fairly convincing evidence exists for an increase of the orbital period with time. In addition to the orbital motion we nd further periods in the orbital residuals. The longest period of 57: d 7 is most likely due to a third body which has the mass of a brown dwarf, whereas the period of 1: 48 could be related to the half rotational period of the star. For the spectral types we deduced A1 III for the primary and M for the secondary. Two further periods of 0: d 21 and 0: d 22 give hint to the existence of short-term pulsations in 21 Her. Their period dierence is of the order of the expected rotational period so that one possible explanation could be rotational splitting of nonradial pulsation modes. Because of the very strong aliasing of the data this nding has to be conrmed by observations having a more suitable time sampling, however. The analysis of photometric series and the Hipparcos photometry give no certain evidence for periodic light variations. For Gem, besides the orbital RV variation, no variations with amplitudes larger than about 100 m s 1 could be detected. The orbital elements of Gem are only slightly changed compared to the previously known orbital solution by including our new radial velocities, but their accuracy is improved. For some chemical elements we determined their abundances, NLTE values of C, O, and Na as well as LTE values of Mg, Sc, Fe, Cr, and Ti. We nd the abundances to be rather close to the solar values, only carbon shows a little underabundance.
Investigation of slag cement quality through the analysis of its efficiency coefficient

ABSTRACT The research efforts on the strength development of slag cements have seen a great progress. Such evolution prediction constitutes a major concern of the construction engineers interested in predicting the removing of the framework or the application of the pre-stressing at suitable ages. The slag concrete strength prediction, using some models, has been studied using the equivalent binder concept. This has led to define an efficiency coefficient of slag which determines the latter according to the cement. Results of this investigation indicates that this coefficient characterizes well the slag and enables to predict the slag cement strength at different ages and replacement rate from the reference cement made without slag. This coefficient has been identified according to the age, the replacement rate, the specific surface area of the slag and the curing temperature.
Optimization of enzyme immobilization on magnetic microparticles using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) as a crosslinking agent

Enzyme immobilization is a versatile tool in biotransformation processes to enhance enzyme activity and to secure an easy separation of catalysts and products and the reusability of enzymes. A simple and commonly used method for crosslinking enzymes to a solid support is the zero-length crosslinking agent 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC). This work shows the optimization of the EDC-crosslinking protocol for two enzymes, glucose oxidase (GOx) and horseradish peroxidase (HRP), to functionalized magnetic microparticles. For GOx the optimization of the immobilization parameters pH-value and the enzyme to particle ratio results in activity yields of up to 36%, which is in the usual range for undirected enzyme immobilisations. In contrast, for HRP the activity yield does not exceed 6% even after optimization of the protocols. The main reasons for this unusually low activity yield are the presence of multiple HRP isoforms in the enzyme solution used for immobilisation and the observed tendency of HRP to be inactive even in the case of simple physisorption to the particle surface.
SPHERICAL IMAGES FOR CULTURAL HERITAGE: SURVEY AND DOCUMENTATION WITH THE NIKON KM360

Abstract. The work presented here focuses on the analysis of the potential of spherical images acquired with specific cameras for documentation and three-dimensional reconstruction of Cultural Heritage. Nowadays, thanks to the introduction of cameras able to generate panoramic images automatically, without the requirement of a stitching software to join together different photos, spherical images allow the documentation of spaces in an extremely fast and efficient way. In this particular case, the Nikon Key Mission 360 spherical camera was tested on the Tolentini’s cloister, which used to be part of the convent of the close church and now location of the Iuav University of Venice. The aim of the research is based on testing the acquisition of spherical images with the KM360 and comparing the obtained photogrammetric models with data acquired from a laser scanning survey in order to test the metric accuracy and the level of detail achievable with this particular camera. This work is part of a wider research project that the Photogrammetry Laboratory of the Iuav University of Venice has been dealing with in the last few months; the final aim of this research project will be not only the comparison between 3D models obtained from spherical images and laser scanning survey’s techniques, but also the examination of their reliability and accuracy with respect to the previous methods of generating spherical panoramas. At the end of the research work, we would like to obtain an operational procedure for spherical cameras applied to metric survey and documentation of Cultural Heritage.
CEO duality, state shareholder and CEO turnover: Evidence from Vietnamese stock market

The extant literature shows that the effects of CEO duality and state shareholder on the sensitivity of management turnover to firm performance are mixed. Using a sample of 1,260 firm-year observations from 226 firms listed in Vietnam from 2009 to 2015, we find supporting evidence for manager turnover mechanism. Interestingly, research results show that the negative relationship between firm performance and CEO turnover is weaker when CEOs simultaneously holds chairman positions. These findings imply that the separation of CEO and chairman positions is necessary to enhance corporate governance.
Rational Socially Responsible Investment

Purpose – The purpose of this paper is first to give an in-depth discussion of the criticism of socially responsible investment's (SRI) alleged incompatibility with the concept of rational investment constituting an inferiority to conventional investment so as to disprove unwarranted arguments and identify potential for improvement of SRI. The second objective is to propose a framework that places SRI and conventional investment on the same level of rationality. Methodology – The discussion is based on a literature study. The framework uses a previously published multidimensional optimization approach and embeds it into a new, integrated methodology for investment decisions in the presence of SRI objectives. The framework is empirically evaluated using historic stock market data. Findings – The main findings show that SRI is not necessarily less rational than conventional investment; it can be implemented in an equally stringent and clearly defined methodology. The empirical results prove that investors c.
DYNAMIC CHARACTERISTICS OF MAGNETIC FLUID BASED SLIDING BEARINGS

The dynamic behaviors of magnetic fluid-lubricated slider bearings have been investigated in this paper. For the slider bearing with an inclined film profile, the use of magnetic fluids as lubricants is found to provide an increase in the load carrying capacity, and the stiffness and damping coefficients as compared to the case of a conventional viscous fluid. The dynamic characteristics of slider bearings are improved by using magnetic fluid lubri-cants together with the application of magnetic fields. DOI: http://dx.doi. org/10.5755/j01.mech. 19.5. 5535
XIX .-THE PELVIC MUSCULATURE OF SAURISCHIAN DINOSAURS

Article XIX. -THE PELVIC MUSCULATURE OF SAURISCHIAN DINOSAURS BY ALFRED S. ROMER Von Huene in 1908 first attempted the restoration of the musculature of the pelvic region of the Saurischia. Gregory and Camp ten years later figured the pelvis of Ornitholestes, a member of this group, with a tentative localization of the muscular areas of origin. Subsequently, the dinosaurian pelvis was restudied by Dr. W. K. Gregory and a number of illustrations prepared. Through the kindness of Dr. Gregory, I am permitted to publish two of his figures relating to the Saurischia here (Fig. 1). They will be discussed in the body of this paper.
Analysis on Passivity for Uncertain Neural Networks with Time-Varying Delays

The problem of passivity analysis for neural networks with time-varying delays and parameter uncertainties is considered. By the consideration of newly constructed Lyapunov-Krasovskii functionals, improved sufficient conditions to guarantee the passivity of the concerned networks are proposed with the framework of linear matrix inequalities (LMIs), which can be solved easily by various efficient convex optimization algorithms. The enhancement of the feasible region of the proposed criteria is shown via two numerical examples by the comparison of maximum allowable delay bounds.
