Distributional Characteristics And Stochastic Dominance versus Parametric Analysis In Testing Anomalies In The Emerging Market: Evidence From Jordan

Virtually all previous studies of seasonal variation in stock returns have used mean/variance analysis despite it being well documented that stock returns in developed and emerging markets are non-normally distributed. This paper details the distributional characteristics of emerging Amman financial market returns.  Further more, it uses stochastic dominance and parametric analyses to investigate the turn-of-the-year and the-week effects from 1978 to 2001.   Results indicate that returns of Amman financial market exhibit substantial deviation from normality.  And parametric analysis tests show there is January and week effects.  However, stochastic dominance results indicate that January and week effects are not exist in the AFM. This implies that the results of parametric analysis are being driven by violations of parametric assumptions

Thermal Effects for Shaft-Pre-Stress on Rotor Dynamic System

This Paper outlines study behaviour of rotating shaft with high speed under thermal effects. The method of obtaining the frequency response functions of a rotor system with study whirl effect in this revision the raw data obtained from the experimental results (using Smart Office program) are curve-fitted by theoretical data regenerated from some of the experimental data and simulating it using finite element (ANSYS 12). (FE) models using the Eigen analysis capability were used to simulate the vibration. The results were compared with experimental data show analysis data with acceptable accuracy and performance. The rotating effect causes un-symmetry in the system matrices, resulting in complexity in decoupling the mathematical models of the system for the purpose of modal analysis. Different method is therefore required, which can handle general system matrices rather than symmetrical matrices, which is normal for passive structures. Mathematical model of the system from the test data can be assembled. The frequency response functions are extracted, Campbell diagram are draw and simulated. (FE) is used to carry out such as simulation since it has good capability for Eigen analysis and also good graphical facility.

Offstage Figures Causing Perplexity in Neil Simon's Rumors

يرجع الاهتمام بالمسرح اللامرئي الى العصر الاغريقي حيث كان القدر قوة غامضة لا مرئية تجلب الحزن والمعاناة للشخوص الرئيسة للمسرحيات. وفي المسرح الشكسبيري تحول الاهتمام من القدر الى الانسان كمتحكم بتوجيه مسار احداث المسرحية بقرارته. حيث كان العالم اللامرئي على خشبة المسرح مأهولا بصورة رئيسة بشخصيات بشرية من الماضي ذات تأثير كبير في احداث المسرحيات، وشهد فن المسرحية اهتماما متزايدا بالعقل البشري الذي يستوعب الماضي والحاضر والابعاد المادية وما ورائها. اذ وصل هذا الاهتمام اوجه في مسرحيات القرن العشرين، اذ استخدمت الشخصيات الغائبة عن المسرح اما لتعكس جوانب من العوالم الداخلية للشخصيات المرئية او لتمثل قوى من العالم الخارجي ذات تأثير في العوالم الداخلية للشخصيات المرئية او لتمثل قوى من العالم الخارجي ذات تأثير في تلك العوالم الداخلية. تهدف هذه الدراسة الى بيان اهمية الشخصيات الغائبة عن خشبة المسرح في التكوين النفسي للشخصيات الحاضرة وفي تحديد ادراكهم ورد فعلهم للعالم المحيط بهم وتمثل وتوضح الشخصيات الغائبة جوانب اجتماعية وثقافية مهمه. تتناول الدراسة مسرحية نيل سايمون "شائعات" اذ يوفر غياب شخصيات مهمة في تلك المسرحية للأزواج على خشبة المسرح الفرصة لتفهم بعضهم البعض والتغلب على مشاكلهم الزوجية.The interest in the invisible could be traced back to the Greek theater where fate acted as a mysterious, invisible force that brought sorrow and suffering to the protagonists. In Shakespearean drama, the interest shifted from fate to man as a power, whose action decided the course of events. There, the offstage world was an invisible realm inhabited mainly by absent characters belonging to the past. They exerted a powerful effect on the onstage world. Drama witnessed an increasing interest in the human mind that encompassed the past and the present, the physical and the metaphysical. That interest reached its prime in modern drama. There, the offstage characters acted either as reflections of the inner world of the onstage characters or as representatives of external forces that influenced it. The aim of the present study is to show the significance of the offstage characters in shaping the onstage characters' psychology and their perception of and reaction to the world. The offstage characters denote and illustrate important cultural and social aspects of the twentieth century as reflected in selected American plays through family relationships. In Neil Simon's Rumors (1988), the absence of essential characters gives the onstage couples an insight into their relationships and consequently leads them to overcome their marital problems

Adopting US-GAAP Or IASB Accounting Standards By The Arab Countries

This paper examines whether Arab countries have adopted the standards issued by the International Accounting Standards Board (lASB) or the US-GAAP.  The results of this study show that companies in the Arab world use different accounting rules and regulations for measurement, recognition, and disclosures of financial position and results of operation.  Consequently, comparability of the financial results of different companies in different countries in the Arab world is impaired.  We recommend adopting financial accounting standards issued by the IASB.  Our study shows that adopting IASB standards has a positive impact on the economic development of the Arab countries

Bank Lending Decisions Using Projections: A Case-study Approach

This paper, by emphasizing on the process and dynamics of bank corporate credit decisions, presents a description of an introductory case-study suitable for an undergraduate/MSc banking or business finance course.  The case exists in two parts and is designed for instructors to be able to use only those parts which they consider appropriate to their objectives and time considerations. In two or three seventy-five minute classes—depending on the parts of the case utilized and the time allowed for student interaction—instructors can have students explore the factors that influence the lending decision and focus on the interpretation of the mechanical process used in constructing projected financial statements for the identification of the actual borrowing needs of a specific company.

Effect of light intensity on carbohydrates, lipids contents, and bioethanol production in two algal species of Coelastrella saipanensis and Oscillatoria duplisecta

This study aimed to examine the feasibility of two algal species of Coelastrella saipanensis (Chlorophyceae) and Oscillatoria duplisecta (Cyanophyceae) to produce bioethanol production at different light intensities. In the present study, light-intensity treatments at 27, 36, and 67 µmol m-2 s-1 were used to stimulate bioethanol production from microalga. The effects of these treatments on C. saipanensis and O. duplisecta were investigated on their growth, carbohydrate and lipids contents. The results showed that the stationary phase of C. saipanensis started on the sixth day under light intensities of 27 and 36 µmol m-2 s-1 and on the eighth day under light intensity of 67 µmol m-2 s-1. The stationary stage of blue-green algae O. duplisecta started on day eight, sixth, and seventh under light intensities of 27, 36, and 67 µmol m-2 s-1, respectively. The highest amount of carbohydrate content was 0.182, and 0.310 mg/l for C. saipanensis and O. duplisecta under light intensity of 36 ?mol m-2 s-1. The highest amount of lipid was 0.95 g/l for C. saipanensis under a light intensity of 36 ?mol m-2 s-1, while 0.74 g/L was the highest amount of lipid for O. duplisecta under 67 µmol m-2 s-1 at a light intensity of 36 µmol m-2 s-1. The highest percentage of bioethanol in C. saipanensis and O. duplisecta were 11.35 and 10.23%, respectively. The 18S rRNA and 16S rRNA genes were used for the identification, and the sequences of algae matched those registered in the GenBank (MT375484.1 for C. saipanensis and MW405018.1 for O. duplisecta). The phylogenetic tree of the ITS area was analyzed inside the 18S rRNA and 16S rRNA and the sequences showed a strong resemblance to those species registered in the Genebank

Empirical Testing Of Different Alternative Proxy Measures For Firm Size

This paper examines the relationship among total sales revenue, total assets, book value of equity, and market value of equity for different economic sectors and timeperiods.  Five statistical tools are used to examine the relationship among the different proxies of size of the firm for the period 1999-2002. Our study shows that the relationships among the four measures of the size of the firm are not the same for the different economic sectors and are not stable over time for each economic sector.  Our results suggest that the use of the four measures interchangeably as a proxy for the firm size may not be appropriate

Empirical Testing Of Random Walk Of Euro Exchange Rates: Evidence From The Emerging Markets

This paper utilizes the new non-parametric variance ratio tests based on signs and ranks to examine the random walk hypothesis of Euro exchange rates for 10 Middle Eastern and North African (MENA) currencies.  The results of the new- variance ratio tests reject the random walk hypothesis for all currencies except the Kuwaiti and the Emirate currencies.  Given the improved size and power properties of Wright’s (2000) ranks and signs tests, the results of the new variance ratio tests are robust to the results of the traditional LOMAC variance ratio tests.&nbsp

Analysis of fatigue damage accumulation of test specimens made from S690 and S960

This thesis study and examines the behavior of high strength steels (HSS) during fatigue utilizing S-N curves of models based on the Palmgren-Miner Rule and some invented hypotheses, such as Haibach's model, Corten-Dolan's model and Serensen-Kogajev model. Firstly, a detailed mechanical testing will be done and discussed to ensure creating a proper understanding of the two types of steel that will be the focal point of the research. The curves created are interpolated using measured data form cyclically loaded of the steel to create the relation between the number of cycles the material can withstand before reaching failure state and the level of stress applied on a variety of specimens with different homogenizes but similar characteristics. The accuracy of each model is determined for each grade of steel, the S690 and the S960. Then we will conclude by the end of the work which can be considered suitable and which not of each model and an explanation of the reasoning behind the results achieved to ensure better outcome in future related work.This thesis study and examines the behavior of high strength steels (HSS) during fatigue utilizing S-N curves of models based on the Palmgren-Miner Rule and some invented hypotheses, such as Haibach's model, Corten-Dolan's model and Serensen-Kogajev model.
