Effect of Interest, Moving Average, and Historical Volatility in Forecasting Exchange Prices of Major International Currencies
Marwan Mohammad Abu Orabi,Abdul Aziz F. AA. Saymeh
International Journal of Economics and Finance , 2012, DOI: 10.5539/ijef.v4n5p246
Abstract: Forecasting foreign exchange prices drives the concerns of financial investors and occupies the minds of financial analysts as well. Most Current forecasting formulas used to employ individual financial factors, either fundamental or technical. The purpose of this study is to test the effect of combined financial factors in forecasting future exchange prices of world currencies. This study used one fundamental factor and two technical factors merged in one mathematical formula. Researchers have merged interest rate, historical volatility, and moving average in one formula. Empirical tests included correlation, Covariance tests to measure the magnitude of the linear relation between historical and computed exchange rates; F.Test aimed to show whether the two sets of historical and computed data have the same standard deviation at the specified confidence levels. Data included historical and computed sets of exchange prices of Swiss Franc, Sterling Pound, European Euro, and Japanese Yen against U.S.Dollar.Study period extended for ten years, i.e. 2000-2008.Results reflected high correlation and low covariance and accepted F.test; there were some biases due to extraneous factors which had affected the exchange rates for certain times during the testing period.
The Effect of Interest Rate, Inflation Rate, GDP, on Real Economic Growth Rate in Jordan
Abdul Aziz Farid Saymeh,Marwan Mohammad Abu Orabi
Asian Economic and Financial Review , 2013,
Abstract: The main objective of this study is to investigate the effect of interest rate, inflation rate, and GDP on real economic growth in Jordan over the period 2000-2010. Unit root test (Augmented Dickey-Fuller test) has been exploited to check the integration order of the variables. Acointegration analysis with four variables (economic growth, interest rate, GDP, and inflation level) is employed. Study adopted Johansen test. Findings indicated that both trace test and max eigenvalue static showed that the four equations have significant existent 1% or 5%. It means that all variables have long term equilibrium relationship. Study adopted the same four variables to discuss Granger Causality relationship; findings indicated that inflation causes interest rate. On the other hand all other variables are independent with each other. Regressionwas conducted to test growth rate with interest rate which showed that current interest rate has an influence power on growth rate. Also, regression used to test growth rate with inflation rate; it showed that inflation rate has influence power on growth rate. Finally regression used to test GDP, interest rate, and inflation rate together; results have shown that current GDP and one lag GDP have influence power to growth rate.

Asian Economic and Financial Review , 2012,
Abstract: Accounting, economic, social and political, and slack resources theories provide different perspectives to addressing corporate social responsibility in relation to disclosure, corporate financial performance e.t.c. This paper aims to identify the determinants financial and non financial of corporate social responsibility (CSR) in Jordan .The annual reports determine a sample of 60 industrial companies listed on the Amman Stock Exchange for a period from 2006 to 2010 in Jordan were used as a basis for the study. The results of the analysis imply that companies that are expected to be large in size firm, age of firm, maintaining growth and are highly leveraged are more likely to voluntary disclose social responsibility information. The result lends partial support to agency and political economy theories.

Mediators of Inflammation , 2012, DOI: 10.1155/2012/697489
Abstract: The aim of this study was to measure the levels of high-mobility group box-1 (HMGB1) in the vitreous fluid from patients with proliferative diabetic retinopathy (PDR) and to correlate its levels with clinical disease activity and the levels of vascular endothelial growth factor (VEGF), the angiogenic cytokine granulocyte-colony-stimulating factor (G-CSF), the endothelial cell angiogenic markers soluble vascular endothelial-cadherin (sVE-cadherin), and soluble endoglin (sEng). Vitreous samples from 36 PDR and 21 nondiabetic patients were studied by enzyme-linked immunosorbent assay. HMGB1, VEGF, sVE-cadherin, and sEng levels were significantly higher in PDR patients than in nondiabetics ( ; <0.001; <0.001; 0.003, resp.). G-CSF was detected in only 3 PDR samples. In the whole study group, there was significant positive correlation between the levels of HMGB1, and sVE-cadherin ( , ). In PDR patients, there was significant negative correlation between the levels of sVE-cadherin and sEng ( , ). Exploratory regression analysis identified significant associations between active PDR and high levels of VEGF (odds ratio = 76.4; 95% confidence interval = 6.32–923) and high levels of sEng (odds ratio = 6.01; 95% confidence interval?= 1.25–29.0). Our findings suggest that HMGB1, VEGF, sVE-cadherin and sEng regulate the angiogenesis in PDR. 1. Introduction Ischemia-induced angiogenesis and expansion of extracellular matrix in association with the outgrowth of fibrovascular membranes at the vitreoretinal interface is the pathological hallmark in proliferative diabetic retinopathy (PDR). Vascular endothelial growth factor (VEGF), an endothelial cell mitogen that also enhances vascular permeability, is thought to be the major angiogenesis factor in PDR [1]. In addition, strong evidence indicates that chronic low-grade inflammation is implicated in the pathogenesis of diabetic retinopathy [2, 3]. Sustained proinflammatory responses in diabetic retinopathy are often associated with angiogenesis [2–5]. The causal relationship between inflammation and angiogenesis is now widely accepted [6]. An emerging issue in diabetic retinopathy research is the focus on the mechanistic link between chronic, low-grade inflammation and angiogenesis. High-mobility group box-1 protein (HMGB1) was initially discovered as a nuclear chromatin-binding protein that stabilizes nucleosome formation and facilitates transcription. Necrotic cell death can result in passive leakage of HMGB1 from the cell as the protein is then no longer bound to DNA. In addition, HMGB1 can be actively secreted by

Journal of Management Research , 2011, DOI: 10.5296/jmr.v4i1.1005
Abstract: The study aimed to reveal the reality of time management in travel and tourism companies in Jordan through identifying the loss of time and the reasons for that, whether regulatory or informational, and learn how efficient the management of choke points, and how quickly does customer requests are responded to.The required data has been collected by questionnaire of 14 companies. The main findings of the study is that there is no waste of time in travel and tourism companies in Jordan due to organizational and informational aspect, with the exception of certain matters such as conflict of business goals, there isn't coordination between departments of the company, and there isn't renewed and up-to-date information for decision-maker when taking any decision. The study also found that they don't manage time of choke points efficiently, and they're quick to respond to customer orders, except that it does not provide new tourism products to customers in a rapid and up-to-date wayMost importantly, the study recommended tourism and travel companies in Jordan to work to eliminate or decrease conflict in work objectives, guide the company's departments towards coordination among them, provide up-to-date and renewed information continuously for decision maker, and manage choke points time more efficiently, as well as to provide new tourist products for customers in a rapid and up-to-date way.
The Influence of Infants’ Characteristics on Breastfeeding Attitudes among Jordanian Mothers  [PDF]
Ghada Mohammad Abu Shosha
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.54032
Abstract: Background: Breastfeeding is the desired nutritional method for infants. Some infants’ characteristics were found influential to mothers’ point of views toward breastfeeding. However, the relationship between infants’ characteristics and mothers’ attitudes toward breastfeeding is still uncertain. The aim of this study was to assess infants’ characteristics and their impact on Jordanian mothers’ attitudes toward breastfeeding. Methods: A descriptive cross-sectional design was used. A sample of 130 mothers was selected conveniently from mothers attending four major governmental maternal-child health centers at Zarqa city in Jordan. The Iowa Infant Feeding Attitude Scale along with infants’ characteristics data sheet were used for data collection. Results: A more positive attitude toward breastfeeding was manifest (mean 63.5, SD: 4.67). Positive attitudes toward breastfeeding were higher among women who delivered normally than women who delivered by cesarean section (p = 0.040). In addition, women who had healthy infants were more likely to have positive attitudes toward breastfeeding compared to women with ill infants (p = 0.021). However, women with preterm deliveries were less likely to have positive attitudes compared to women with full-term deliveries (p = 0.013). Likewise, women whose infants admitted to neonatal intensive care unit recorded less positive attitudes toward breastfeeding than women with healthy neonates (p = 0.043). Gestational age, admission to neonatal intensive care unit, infant’s health status, and type of delivery, were factors influencing mothers’ attitudes towards breastfeeding. Conclusions: Jordanian mothers have positive attitudes toward breastfeeding. However, positive attitudes are subject to different infants’ characteristics that should be considered while undertaking heath education programs for promoting breastfeeding. More focusing is recommended for women who delivered preterm infants, women who have ill infants, and women who delivered by cesarean section.

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.614156
Abstract: This study aims to investigate the level of inclusion and balance of multiple intelligences in the Arabic Language textbooks in light of Gardner’s Theory using the analytical descriptive approach. Eight textbooks in grades (1 - 4) for the first and second semesters were taught in schools in the Jordanian educational system in 2013/2014. The selected textbooks were analyzed using Multiple Intelligences (MI) checklist devised by the researcher based on the framework of the Theory of Multiple Intelligences to examine them in relation to different intelligences as reflected through various activities, questions and tasks. The study sample consisted of all Arabic Language textbooks for the grades from 1 - 4. Results of the study showed that the verbal/linguistic intelligence in the textbooks in general scored the highest frequency amongst all types of intelligence; meanwhile the musical intelligence in the textbooks scored the lowest frequency among all types of intelligence. The study concluded with a recommendation to consider the necessity of employing all types of intelligence in designing Arabic language textbooks for young learners.
Keep on Striving: The Impact of Psychosocial Support on Jordanian Adolescents with Cancer  [PDF]
Ghada Mohammad Abu Shosha
Health (Health) , 2016, DOI: 10.4236/health.2016.810095
Abstract: Having cancer during adolescence stage causes stressors in patients’ lives. They are responsible for dealing with many new situations and stressors. Coping with such stressors can be influenced by psychosocial factors. This study aimed to explore the impact of psychosocial support on adolescents with cancer. A qualitative exploratory design was used to understand the experience of psychosocial support from the perspectives of the patients. Twenty adolescents with cancer were selected purposefully from two major cancer treatment centers in Jordan. Semi-structured face-to-face interviews were used to obtain the participants’ perspectives. Data were analyzed using thematic analysis approach. Findings revealed three major themes: “supportive structure”, “precious aspects of psychosocial support”, and “cancer could be defeated”. Participants expressed their satisfaction with the psychosocial support provided to them. However, they asked for further improvement in hospital facilities, playrooms and leisure activities. In conclusion, having a strong psychosocial support system will help adolescents to cope with cancer. Family, friends, and the surrounding environment are the key elements in installing hope and helping adolescents to go through cancer experience. Nurses are advised to adopt these psychosocial keys in order to create age-related activities that would improve the patients’ coping with cancer.
