    Rusbult’s Investment Model Validity for Explaining Remaining in Abusive Relationship for Sample of Jordanian Abused Women

    Get PDF
    This study aimed to explore Caryl Rusbult’s model validity for explaining women remaining in an abusive relationship for available sample of 35 Jordanian abused women and living in the abusive relationship who are contacting the women and child health center in Prince Faisal Hospital. The World Health Organization (WHO) Domestic Violence (DV) scale and Rusbult’s Investment Model Scale (IMS) were used. The results revealed low levels of Marriage Satisfaction (MS) and Quality of Alternatives (QA). Moderate levels of Relationship Investment size (RI) and Marriage Commitment (MC) were found. The result also indicated that there were not significant statistical differences between the IMS scale dimensions (MS, RI and QA) and women's commitment in relationship variable. The results indicated the validity of the investment model to be applied to Jordanian culture

    Modeling Of Structural And Environmental Effects On Microelectromechanical (Mems) Vibratory Gyroscopes

    In this paper we investigate the effects of stiffness, damping and temperature on the performance of a MEMS vibratory gyroscope. The stiffness and damping parameters are chosen because they can be appropriately designed to synchronize the drive and sense mode resonance to enhance the sensitivity and stability of MEMS gyroscope. Our results show that increasing the drive axis stiffness by 50% reduces the sense mode amplitude by ~27% and augments the resonance frequency by ~21%. The stiffness and damping are mildly sensitive to typical variations in operating temperature. The stiffness increases by 1.25%, while the damping decreases by 3.81%, when the temperature is raised from 0C to 45C. Doubling the damping reduces the oscillation amplitude by 80%, but ~1% change in the frequency. The predicted effects of stiffness, damping and temperature can be utilized to design a gyroscope for the desired operating condition

    Dequantizing Compressed Sensing: When Oversampling and Non-Gaussian Constraints Combine

    In this paper we study the problem of recovering sparse or compressible signals from uniformly quantized measurements. We present a new class of convex optimization programs, or decoders, coined Basis Pursuit DeQuantizer of moment pp (BPDQp_p), that model the quantization distortion more faithfully than the commonly used Basis Pursuit DeNoise (BPDN) program. Our decoders proceed by minimizing the sparsity of the signal to be reconstructed subject to a data-fidelity constraint expressed in the p\ell_p-norm of the residual error for 2p2\leq p\leq \infty. We show theoretically that, (i) the reconstruction error of these new decoders is bounded if the sensing matrix satisfies an extended Restricted Isometry Property involving the p\ell_p norm, and (ii), for Gaussian random matrices and uniformly quantized measurements, BPDQp_p performance exceeds that of BPDN by dividing the reconstruction error due to quantization by p+1\sqrt{p+1}. This last effect happens with high probability when the number of measurements exceeds a value growing with pp, i.e. in an oversampled situation compared to what is commonly required by BPDN = BPDQ2_2. To demonstrate the theoretical power of BPDQp_p, we report numerical simulations on signal and image reconstruction problems

    The first time report on the feeding ecology and food preference of mangrove horseshoe crab Carcinoscorpius rotundicauda (Latreille 1802) at their nesting grounds along the Pahang coast is given. Monthly sampling was carried out between March 2010 and February 2011 covering both monsoonal (March to October) and non-monsoonal (November to February) seasons. Major macrobenthic gut contents (bivalves, gastropods, crustaceans, polychaetes and miscellaneous food items including plant materials) were identified using microscopic examination. An electivity index (E1) was calculated for the frequent food items observed in the gut region of C. rotundicauda during monsoon and non-monsoon seasons. The EI was negative for crustaceans and positive for all the other food items including bivalves, gastropods, polychaetes and miscellaneous food items (which include insects, amphipods, Isopods, larval and juvenile stages of fishes, foraminifera and other Annelid worms). It is interesting to note that C. rotundicauda prefered less number of bivalves than polychaetes during non monsoon seasons but it was the reverse during monsoonal period. Male crabs intensely preyed on gastropods and female prefers polychaete worms during the peak mating/nesting season (June - August 2010). Seasonal variations in food composition showed that mollusks formed the main item especially gastropods. Unidentified organic matters in the gut content analysis of C. rotundicauda showed high preference towards plant materials. Gastro Somatic Index (GaSI) analysis showed that the feeding intensity of male crabs was higher during non-monsoon period while it was higher during monsoonal period in female crabs. In conclusion, the feeding ecology of mangrove horseshoe crabs were more similar to its closer and distant conspecifics. However, it was postulated that the higher preference of polychaete worms by the female C. rotundicauda during the peak mating season indicated its role in regulating the nesting behaviour

    Nowadays, there is a wide using of mobile and internet from various ages, due to some bad systems which they work to send signals(sound wave frequency) within the music or will be spread to affect the brain of the humankind. Therefore, this paper expresses thedetection and evaluation of (the signal of sound frequency) which influence the human brain, it has been measured some frequency byprogramming in the mobile and found a trend to detect such frequencies and a way to produce a human being from it

    هدفت الدراسة إلى اختبار فاعلية برنامج إرشاد جمعي افتراضي قائم على التعليم النفسي في مستويات الرضا الزواجي لدى طلبة الجامعة المتزوجين. اشتملت الدراسة على 24 طالباً متزوجاً في الجامعة الهاشمية، وزعوا مناصفة عشوائياً إلى مجموعتين ضابطة وتجريبية. استخدمت قائمة الرضا الزواجي المكونة من خمسة أبعاد: الضغط العام والاتصال لحل المشكلات والاتصال المتعاطف وقضاء الوقت معاً والإشباع الجنسي لتقييم مستويات الرضا الزواجي. اشتمل البرنامج الإرشادي على 10 جلسات جماعية افتراضية، بواقع جلسة واحدة أسبوعياً، ومدة كل جلسة 120 دقيقة. أشارت النتائج إلى وجود فروق ذات دلالة إحصائية بين متوسطات الرضا الزواجي في القياس البعدي لأفراد مجموعتي الدراسة لصالح أفراد المجموعة التجريبية، مما يظهر فاعلية البرنامج الإرشادي الجمعي في تحسين مستويات الرضا الزواجي لدى الطلبة المشاركين. كذلك أظهرت النتائج وجود فروق ذات دلالة إحصائية بين القياس البعدي والقياس التتبعي لأفراد المجموعة التجريبية -لمدة 3 أشهر بعد الانتهاء من البرنامج الإرشادي- في جميع أبعاد قائمة الرضا الزواجي، باستثناء بعد الضغط العام، ولصالح القياس البعدي، مما يشير إلى عدم احتفاظ أفرادها بالمكتسبات العلاجية التي تم إحرازها من البرنامج
