العلاقة بين موقف الحساب الجاري وسعر الصرف (حالة الولايات المتحدة)
...Show More Authors

خضعت العلاقة بين موقف الحساب الجاري, سواء اكان بحالة عجز ام فائض, وسعر الصرف, اكان بحالة انخفاض او ارتفاع, لجدل واسع بين اوساط الاقتصاديين بشأن هذه العلاقة واتجاهاتها.

الا ان الاعتماد المتزايد لبعض الدول على المستثمرين الاجانب لتمويل العجز في حساباتها الجارية قد يصطدم بعدم رغبة هولاء المستثمرون في الاستمرار باقتناء موجودات معينة مقوِِِِِِِِمة بعملات تلك الدول. وتنشأ الطامة الكبرى لاقتصاديات وعملات هذه الدول عندما يقرر المستثمرون التخلي عن هذه الموجودات كلية (بيعها) .

وكان المضاربون على هبوط العملات bears يؤكدون على ان زيادة عجز الحساب الجاري لدولة ما  يفضي بالضرورة الى انخفاض حاد في قيمة تلك العملة. الا ان هؤلاء المضاربين قد ثبت خطا تقديراتهم في عدة مواضع .

فعلى الرغم من تفاقم عجز الحساب الجاري الامريكي في عقد التسعينات الى مستويات قياسية, فقد ارتفعت قيمة الدولار, ولم تنخفض خلال تلك  المدة, كما هو من المفروض ان يحصل.

ان الغرض من هذا البحث هو تحديد علاقة عجز الحساب الجاري بسعر الصرف على المدى المتوسط والطويل. ويبدأ البحث بمناقشة العوامل الاساسية التي اسهمت بتوسيع عجز الحساب الجاري الامريكي مع الاشارة الى تدهوره في الاونة الاخيره الى مستويات قياسية.

ثم يعرج البحث لمناقشة في ما اذا كانت هذه الزيادة في العجز تمثل ظاهرة اختلالية يتحتم تصحيحها  او ان هناك عوامل معينة تجعل الولايات المتحدة تتحمل عجوزات كبيرة بالحساب الجاري بشكل اكبر من المستوى الطبيعي (بشكل مستدام ولسنوات قادمة) .

إن التطورات التكنولوجية في مضمار تكنولوجيا المعلومات قد افضت الى رفع المعدل الذي نما به الاقتصاد الأمريكي بدون استفحال التضخم في عقد التسعينات. كما إن الإنفاق الاستثماري الأمريكي ارتفع في ذات المدة, بسبب الابتكارات المثيرة في تكنولوجيا المعلومات, مما أفضى إلى إحداث فجوة متوسعة باستمرار بين المدخرات والاستثمار الأمريكي لصالح الأخير.

وطالما ان عجز الحساب الجاري يساوي الفجوة بين المدخرات والاستثمار, فأن الفجوة المتزايدة بين الاستثمار والمدخرات المحلية تتضمن وجود عجز متزايد باستمرار في الحساب الجاري.

ثم يحاول البحث التعريج على اهم الطرق المختلفة لمعالجة عجز الحساب الجاري من الناحية النظرية والتطبيقية .

ويختتم البحث بملاحظات استنتاجيه عن علاقة موقف الحساب الجاري وسعر الصرف وأثره عليه عبر عدة قنوات . ويلخص بما توصل إليه البحث بشأن دراسة الحالة (الولايات المتحدة) .

Comparison between the empirical bayes method with moments method to estimate the affiliation parameter in the clinical trials using simulation
...Show More Authors

In this research the Empirical Bayes method is used to Estimate the affiliation parameter in the clinical trials and then we compare this with the Moment Estimates for this parameter using Monte Carlo stimulation , we assumed that the distribution of the observation is binomial distribution while the distribution with the unknown random parameters is beta distribution ,finally we conclude that the Empirical bayes method for the random affiliation parameter is efficient using Mean Squares Error (MSE) and for different Sample size .

Comparison of Multistage and Numerical Discretization Methods for Estimating Parameters in Nonlinear Linear Ordinary Differential Equations Models.
...Show More Authors

Many of the dynamic processes in different sciences are described by models of differential equations. These models explain the change in the behavior of the studied process over time by linking the behavior of the process under study with its derivatives. These models often contain constant and time-varying parameters that vary according to the nature of the process under study in this We will estimate the constant and time-varying parameters in a sequential method in several stages. In the first stage, the state variables and their derivatives are estimated in the method of penalized splines(p- splines) . In the second stage we use pseudo lest square to estimate constant parameters, For the third stage, the rem

A comparison among Different Methods for Estimating Regression Parameters with Autocorrelation Problem under Exponentially Distributed Error
...Show More Authors

Multiple linear regressions are concerned with studying and analyzing the relationship between the dependent variable and a set of explanatory variables. From this relationship the values of variables are predicted. In this paper the multiple linear regression model and three covariates were studied in the presence of the problem of auto-correlation of errors when the random error distributed the distribution of exponential. Three methods were compared (general least squares, M robust, and Laplace robust method). We have employed the simulation studies and calculated the statistical standard mean squares error with sample sizes (15, 30, 60, 100). Further we applied the best method on the real experiment data representing the varieties of

Performance Comparison of Different Advanced Control Schemes for Glucose Level Control under Disturbing Meal
...Show More Authors

Abstract

In this work, diabetic glucose concentration level control under disturbing meal has been controlled using two set of advanced controllers. The first set is sliding mode controllers (classical and integral) and the second set is represented by optimal LQR controllers (classical and Min-, ax). Due to their characteristic features of disturbance rejection, both integral sliding mode controller and LQR Minmax controller are dedicated here for comparison. The Bergman minimal mathematical model was used to represent the dynamic behavior of a diabetic patient’s blood glucose concentration to the insulin injection. Simulations based on Matlab/Simulink, were performed to verify the performance of each controll

Employment and Labor Union Laws in Japan between the 1889 and 1946 Constitutions: A Comparative Study: أفراح محمد علي
...Show More Authors

This research is based on the descriptive and analytical methodology. The importance of studying labor laws and labor unions in Japan between 1889 and 1946 constitutions is because Japan was out of a feudal phase, and had no idea about the factory system and industrialization in their modern sense before the Meiji era. Generally, its labor system used to be mostly familial, and the economic system was based on agriculture. This called for the enactment of legislations and laws appropriate for the coming phase in Meiji era. Thus, this paper examines the role of Meiji government in enacting labor legislations and laws when he came to power in 1896, and his new constitution in 1889 and the civil code of 1896. It further examines the way Mei

Prediction of the Scale Removal Rate in Heat Exchanger Piping System Using the Analogies between Mass and Momentum Transfer
...Show More Authors

The possibility of predicting the mass transfer controlled CaCO3 scale removal   rate has been investigated.

Experiments were carried out using chelating agents as a cleaning solution at different time and Reynolds’s number. The results of CaCO3 scale removal or (mass transfer rate) (as it is the controlling process) are compared with proposed model of prandtl’s and Taylor particularly based on the concept of analogy among momentum and mass transfer.

Correlation for the variation of Sherwood number ( or mass transfer rate ) with Reynolds’s number have been obtained .
