This paper seeks to better understand the distribution of realized stock retum volatility and to detennine how this volatility reacts to past and expected changes in monetary and other macro aggregates. 1 follow Schwert's (1989) methodology to investigate the relationship between stock market volatility and the level of the economy. While Schwert (1989) uses daily retums to estimate monthly variance, 1 use the fonner to compute quarterly volatility; therefore my estimates have less error. Furthermore, my model corrects for potential endogeneity and seriai correlation problems that are evident in Schwert (1989). In addition, 1extend my study to NYSE and NASDAQ stock markets data. ln sum, my study supports Schwert's (1989) findings. Money supply and industrial production shocks are predictors of market voJatility variations; while short tenn interest rates do not affect equity market volatility. Nevertheless, my empirical results don 't support Schwert (1989) finding that market volatility is not linked to inflation variations. Finally, to sorne extent, my findings suggest that the efficient market hypothesis is rejected. The actual federal fund rate, money supply, inflation and industrial capacity utilization rate help to predict future equity market volatility.
Effects of Rapid Thermal Annealing Temperature on Performances of Nanoscale FinFETs

In the present work three dimensional process and device simulations were employed to study the performance variations with RTA. It is observed that with the increase in RTA temperature, the arsenic dopants from the source /drain region diffuse laterally under the spacer region and simultaneously acceptors (Boron) are redistributed from the central axis region of the fin towards the Si/SiO2 interface. As a consequence both drive current and peak cut-off frequency of an n-FinFET are observed to improve with RTA temperatures. Volume inversion and hence the flow of carries through the central axis region of the fin due to reduced scattering was found behind the performance improvements with increasing RTA temperature.
A simple approach to the joint inversion of seismic body and surface waves applied to the southwest U.S.

Body and surface wave tomography have complementary strengths when applied to regional‐scale studies of the upper mantle. We present a straight‐forward technique for their joint inversion which hinges on treating surface waves as horizontally‐propagating rays with deep sensitivity kernels. This formulation allows surface wave phase or group measurements to be integrated directly into existing body wave tomography inversions with modest effort. We apply the joint inversion to a synthetic case and to data from the RISTRA project in the southwest U.S. The data variance reductions demonstrate that the joint inversion produces a better fit to the combined dataset, not merely a compromise. For large arrays, this method offers an improvement over augmenting body wave tomography with a one‐dimensional model. The joint inversion combines the absolute velocity of a surface wave model with the high resolution afforded by body waves—both qualities that are required to understand regional‐scale mantle phenomena.
Gear Crack Level Classification Based on EMD and EDT

Gears are the most essential parts in rotating machinery. Crack fault is one of damage modes most frequently occurring in gears. So, this paper deals with the problem of different crack levels classification. The proposed method is mainly based on empirical mode decomposition (EMD) and Euclidean distance technique (EDT). First, vibration signal acquired by accelerometer is processed by EMD and intrinsic mode functions (IMFs) are obtained. Then, a correlation coefficient based method is proposed to select the sensitive IMFs which contain main gear fault information. And energy of these IMFs is chosen as the fault feature by comparing with kurtosis and skewness. Finally, Euclidean distances between test sample and four classes trained samples are calculated, and on this basis, fault level classification of the test sample can be made. The proposed approach is tested and validated through a gearbox experiment, in which four crack levels and three kinds of loads are utilized. The results show that the proposed method has high accuracy rates in classifying different crack levels and may be adaptive to different conditions.
Decentralisation of Education System - a Panacea for School Improvement Issues? The Georgian Perspective

Almost a decade ago, Georgia, a Trans-Caucasian state, embarked on educational decentralisation reform aiming at rehabilitation of education system in order to reach high school performance. Through Local Management of Schools, the form of decentralisation implemented in Georgia, power and authority was devolved directly to individual schools. Due to the initiative principals became the fulcrum of all reform efforts. Thus the aim of the study was to observe how the central state reform informs policy and practice at school level through empowered principals and whether the new initiative was actually the answer to the accumulated educational issues. The study showed that while most principals had broad understanding of the reform, many lacked practical skills and experience in actual governance in a new mode. School governance was further complicated by insufficient funds from the central government, low community participation in school functioning and teachers' lack of training in conducting teaching and learning process in a new mode set by the new National Curriculum.
Enhancing Communication Within Multi-Generational organizations

In order to capture the essence of employee dynamics within the ever-changing landscape of modern organizations, a naturalistic inquiry using a holistic approach was employed. This technique emphasized the millennial generation’s communication strengths as compared to those of previous generation workers. The perceptions of millennial students, millennial workers, multi-generational managers, university professors, and IT professionals were analyzed through a constant, comparative analysis and grouped so that grounded theory was allowed to emerge. The products of this inquiry include practical solutions aimed at reducing the uncertainty for multi-generational managers, specifically regarding the supervision of younger generation workers. In addition, the results of this study suggest that traditional business communication practices, when coupled with an increased use of information and communication technologies that are specifically designed to bolster collaboration and interpersonal communication, have the potential to maximize internal and external communication effectiveness. The data collected within this study provided an overview of the underlying values and perceptions behind millennial behavior. This synopsis, captured through millennial focus groups and face-to-face interviews, acquiesces to the literature surrounding the millennial generation. As outwardly portrayed, the individuals within this study are technically advanced, goal-oriented people who want the freedom and balance to work efficiently and effectively. In addition, the millennials used herein respect the traditional organizational structure, but only to the limit that its hierarchical nature does not stunt innovation achieved through adaptability and collaboration.

Purpose – the aim of this paper is to analyse the diffusion and efficiency of ISO 9001 on different sectors of activity Design/methodology/approach – for that purpose, a holistic an integrative theoretical approach was based on the scope of the Contingency theory, the Institutional theory and the Resources-Based View (RBV). This theorethical perspective was used in a broad empirical study, using a qualitative and quantitative methodology, concerning Portuguese companies from different sectors of activity. Findings – according to the findings from both perspectives, a ranked combination of the named theoretical frame was constructed. Research limitations/implications – as to the analysis of the efficiency of ISO 9000, one of the limitations of this study lays in the consideration of just two sectors of activity, and another relates to its domestic geographical placement. Practical implications – this study used the ISO 9001 structure for the interviews and this has revealed very useful for the organizations to grasp the matters inquired. Originality/value – a relevant contribution to the state of art is achieved through the considered theoretical scope of analysis
Perspectives on the simulation of micro gas and nano liquid flows

Micro- and nano-scale fluid systems can behave very differently from their macro-scale counterparts. Remarkably, there is no sufficiently accurate, computationally efficient, and — most importantly — generally agreed fluid dynamic model that encapsulates all of this important behaviour. The only thing that researchers can agree on is that the conventional Navier-Stokes fluid equations are unable to capture the unique complexity of these often locally non-thermodynamic-equilibrium flows. Here, we outline recent work on developing and exploring new models for these flows, highlighting, in particular, slip flow as a quintessential non-equilibrium (or sub-continuum) phenomenon. We describe the successes and failures of various hydrodynamic and molecular models in capturing the non-equilibrium flow physics in current test applications in micro and nano engineering, including the aerodynamic drag of a sphere in a rarefied gas, and the flow of water along carbon nanotubes.Copyright © 2011 by ASME

The metals analyzed were: Cd, Cu, Cr, Fe, As, Pb, Zn and Ni. The metal analysis was performed by Atomic Absorption Spectrometer. The result showed that Ni and Cu were absent in all samples while considerable concentrations of other metals were present.
An Assessment of the Extent to Which Zimbabwean Organizations Have in Practice Begun to Make the Shift Towards Triple Bottom Line Reporting (TBL).

The purpose of the study was to assess the extent to which corporations in Zimbabwe make shifts towards the triple bottom line reporting and asses the balance of the three Ps. This was done through a content analysis of company annual reports of 40 listed companies in Zimbabwe for period 2009 to 2012. The assessment criteria comprised among others of TBL balance, inclusion of TBL elements in reporting, environmental policy in place and reported, stakeholder assurance, GPI reporting, Quantification of the other two Ps, any Environmental award obtained. Results showed that companies in Zimbabwe generally are making shifts towards the TBL reporting although not remarkable. Whilst companies are making shifts towards the TBL reporting, the standard of reporting is still below one’s expectation as there are a lot of irregularities between companies and sectors. Considerable coverage was realized in the mining sector, Beverage, Food processing, and Building and associated industries’ sectors. Since there is no specific law that makes TBL reporting mandatory, variations in terms of consistence and quality will always be a norm hence, it was recommended that environmental and social audits by the government agencies like the Environmental Management Agency, Ministry of Environment and Tourism and NSSA among others
Tectonic controls of Holocene erosion in a glaciated orogen

Abstract. Recent work has highlighted a strong, worldwide, alpine glacial impact on orogen erosion rates over the last 2 Ma. While it may be assumed that glaciers increased erosion rates when active, the degree to which past glaciations influence Holocene erosion rates through the adjustment of topography is not known. In this study, we investigate the influence of long-term tectonic and post-glacial topographic controls on erosion in a glaciated orogen: the Olympic Mountains, USA. We present 14 new 10Be and 26Al analyses which constrain Holocene erosion rates across the Olympic Mountains. Basin-averaged erosion rates scale with basin-averaged values of 5 km local relief, channel steepness, and hillslope angle throughout the range, similar to observations from non-glaciated orogens. These erosion rates are not related to mean annual precipitation or the marked change in Pleistocene alpine glacier size across the range, implying that glacier modification of topography and modern precipitation parameters do not exert strong controls on these rates. Rather, we find that despite spatial variations in glacial modification of topography, patterns of recent erosion are similar to those from estimates of long-term tectonic rock uplift. This is consistent with a tectonic model where erosion and rock uplift patterns are controlled by the deformation of the Cascadia subduction zone.
RELIABILITY ANALYSIS OF TYPICAL COLD-FORMED STEEL BEAMS SECTIONS

This paper presents a reliability analysis of cold-formed steel beams, based on the FORM and MC simulation and using data obtained from experimental tests performed at the Johns Hopkins University, Baltimore (Schafer, 2003; 2006). This paper approached two sets of flexural tests, one referring to the failure by local buckling, and another for distortional buckling. A failure function is assembled to obtain, by taking into account the statistical parameters of the material (M), fabrication (F), and professional factors (P). The material and fabrication factors were taken from AISI standard. The professional factor was determined by comparing the tested failure loads and the predicted ultimate loads calculated from the selected design provisions. The goal of the paper is the assessment of reliability index for two nominal live-to-dead load ratios, as well as to compare the value found considering the load combinations for ultimate limit states. Keywords: Reliability, Steel Beams, Buckling, Cold-formed stee.
Earnings Management in the Financial Crisis 2007/2008 : Evidence from German-Speaking Countries

We investigate the financial crisis's impact on earnings management behavior in the German-origin banking sector during the financial crisis 2007/2008. Controlling for similar institutional settings and company differences, we use four different earnings management measures (discretionary loan loss provisions, small gains/great losses, market to book ratio and an aggregate ranking index) in accordance with prior literature and find an increase in earnings management during the crisis. Using a relatively small data sample allows us to analyze earnings management on the individual company level and therefore we are able to reveal differences among the observed firms. Earnings management is found to be used with balance sheet as well as income statement items and is additionally driven by company size, the role of equity markets for firm financing and the fragmentation of shareholders. Overall, the results indicate a decrease in the informativeness of earnings for market participants. =>> http://aaahq.org/AM2010/abstract.cfm? submissionID=428
Pre and post-moult productive efficiency in four varieties of indigenous Aseel chicken during different production cycles.

The objective of current study was to assess the effect of moulting on productive efficiency in Aseel chickens at different phases of age. A total of 168 hens, 42 from each of four varieties (Mushki, Lakha, Mianwali and Peshaw ari) divided into 3 age groups, young (50-67 weeks), medium (80 -97 weeks) and old (115-132 weeks) were maintained in cages during pre and post-moult phases. The data thus collected during both the phases were subjected to analysis of variance in Randomized Complete Block Design. The results showed that overall productive efficiency remained better in post moult as compared to pre-moult phase. Mushki showed significantly higher egg production, egg mass, egg weight, and better FCR/ dozen eggs. Feed intake was higher in Peshawari variety while, body weight and FCR/Kg egg mass showed non-significant differences. The birds of younger age showed significantly higher feed intake, egg mass, egg production, and better FCR/dozen eggs, while, egg weight and FCR/kg egg mass were not affected by age. Older birds showed significantly higher body weight. Key word: Aseel Chicken, Production performance, Pre-moult, Post-moult, Variety

Exfoliation of single layer BiTeI flakes

Spin orbit interaction is strongly enhanced in structures where a heavy element is embedded in an inversion asymmetric crystal field. A simple way for realizing such a setup is to take a single atomic layer of a heavy element and encapsulate it between two atomic layers of different elemental composition. BiTeI is a promising candidate for such a 2D crystal. In its bulk form BiTeI consists of loosely coupled three atom thick layers where a layer of high atomic number Bi are sandwiched between Te and I sheets. Despite considerable recent attention to bulk BiTeI due to its giant Rashba spin splitting, the isolation of a single layer remained elusive. In this work we report the first successful isolation and characterization of a single layer of BiTeI using a novel exfoliation technique on stripped gold. Our scanning probe studies and first principles calculations show that the fabricated 100 μm sized BiTeI flakes are stable at ambient conditions. Giant Rashba splitting and spin-momentum locking of this new 2D crystal opens the way towards novel spintronic applications and synthetic topological heterostructures.
The Impact of Corruption Distance on Ownership Strategies of Spanish and Portuguese MNEs

The ownership strategy of foreign subsidiaries is an important decision for multinational enterprises (MNEs). Previous research has analyzed the effect of country dimensions on this strategy, both from the home and the host country. In this paper we delve into the effect of differences between home and host country on the MNEs’ ownership strategies. Empirically, we analyze the influence of corruption distance on the ownership strategies of Spanish and Portuguese MNEs, using data from 3,941 foreign subsidiaries. We found that the higher the absolute corruption distance between Spain (or Portugal) and the host country, the higher the ownership controlled by MNEs. However, when the host is more corrupt than the home country, MNEs have a lower ownership level in the local subsidiaries.
USING MACHINE LEARNING TECHNIQUES FOR FINDING MEANINGFUL TRANSCRIPTS IN PROSTATE CANCER PROGRESSION

Prostate Cancer is one of the most common types of cancer among Canadian men. Next generation sequencing that uses RNA-Seq can be valuable in studying cancer, since it provides large amounts of data as a source for information about biomarkers. For these reasons, we have chosen RNA-Seq data for prostate cancer progression in our study. In this research, we propose a new method for finding transcripts that can be used as genomic features. In this regard, we have gathered a very large amount of transcripts. There are a large number of transcripts that are not quite relevant, and we filter them by applying a feature selection algorithm. The results are then processed through a machine learning technique for classification such as the support vector machine which is used to classify different stages of prostate cancer. Finally, we have identified potential transcripts associated with prostate cancer progression. Ideally, these transcripts can be used for improving diagnosis, treatment, and drug development.
Countertransference Behavior and Management in Brief Counseling: A Field Study

The relationship between countertransference (CT) behavior and factors theorized to facilitate CT management was examined in a study of 20 counseling dyads. Previous supervisors' ratings of counselors' empathy and self-integration were found to relate negatively to counselors' CT behavior. Furthermore, CT behavior was inversely related to treatment impact in cases with poor to moderate treatment results but was unrelated to treatment impact in successful cases. These data suggest that CT is not successfully managed in cases with poor to moderate treatment results so that the adverse effect on treatment results is proportionate to the amount of CT exhibited. In successful counseling, however, CT may be managed in such a way that the overall amount present is unrelated to treatment results.Die Beziehung zwischen Gegenubertragungsverhalter und Faktoren, die theoretisch dessen Handhabung erleichtern sollten, wurde im Rahmen einer Untersuchung von 20 Beratungsdyaden untersucht.

Gray optimization of process parameters of surface modification of coconut sheath reinforced polymer composites

Abstract Surface modification of natural fiber may greatly enhance the mechanical interlocking between fiber and matrix. Although there are many reports on surface modification of natural fibers, little technical information is available to enable the selection of optimized surface modification conditions. In this work, treatment parameters, such as bath temperature, agent concentration, and treatment time, are optimized to achieve higher interfacial adhesion. The effect of these parameters on flexural and impact strength is investigated by applying gray relational techniques. Experimental results show that NaOH concentration and treatment time are significant variables which improve interfacial strength, while NaOH bath temperature appears less important.
