Code-choice on Twitter: How stance-taking and linguistic accommodation reflect the identity of polyglossic Egyptian users

This study examines the online identity of polyglossic Egyptian users of Twitter. It is descriptive and exploratory utilizing a qualitative design with some frequency count which adds descriptive data. Data were collected using a Discourse Completion Task (DCT) where the participants were presented with a number of tweets and were asked to type another tweet in response to each. The findings from the study suggest that polyglossic Egyptians, those who are proficient in English as well as Arabic, exhibited an assertive identity on Twitter. This identity was constructed through the choice of code, the linguistic accommodation to the tweet authors, and the stance they took. Polyglossic Egyptians were found to use English more than any other code, followed by Arabizi, and then Arabic. They linguistically accommodated the tweet authors in their replies to some extent by choosing the same code in replying as that used in the original tweet. Further, and using Du Bois’ (2007) stance triangle framework, it was also found that they expressed their (dis)alignment quite bluntly by taking an epistemic stance achieved through the use of boosters (very few hedges were used), sarcasm, simple present tense (to express an opinion as if stating a fact), and modals (to offer advice). By doing that, polyglossic Egyptians were found to be assertive in expressing their opinions, often showing themselves as informative, superior people who are guided by facts about topics rather than feelings

Does The Foreign Direct Investment Affect Economic Growth in Jordan in Light of Commercial Openness

Purpose: This paper aims to examine the effect of foreign direct investment on economic growth in Jordan in light of the trade openness, during the period from 1999 to 2019.   Theoretical Framework: This paper discusses how Jordan, as a developing country, has worked over the years to attract foreign investment by creating an environment of incentives, benefits, and legislation that encourages such investments; taking advantage of low local labor wages, high administrative costs, and great commercial openness.   Design/methodology/approach: To achieve the objectives of the study and to construct the statistical model the study used analytical methodology. The following statistical methods were applied; Hausman, Wald Test, F-Test Statistic, Granger, Multicollinearity test, Normality Test, Lagrange Test, Multiplier Test, and Causality Test.   Findings: After conducting the analysis tests, the results showed a statistically significant impact of open trade direct investment on economic growth, Moreover, findings showed a positive impact on the degree of economic growth, whenever the degree of trade openness and the flow of foreign investment increase.   Research, Practical & Social implications: The independent variables in the study model were measured by the ratio of foreign direct investment from the nominal GDP. The variable (the degree of trade openness) was expressed as the ratio of exports and imports to trade volume. The generalized Method of Moments (GMM) was used in this study.   Originality/value: In light of Jordan's extensive commercial openness, This investigation looked at the impact of FDI on economic expansion. The study's findings are in line with theoretical research and other studies that hold that a country's level of economic growth is not adversely affected by significant trade openness because foreign investments are not less effective

The Effect of Supply Shock and Demand Shock on the Foreign Currencies Exchange Rate Pass – Through to Price Index in Jordan (1990 –2013)

This study aims to identify the variables ( supply and demand shocks) affecting foreign currencies exchange rate pass–through to price index in Jordan , over the years ( 1990- 2013) to determine their effect and transfer to domestic price index.To achieve this goal, the researcher modifying (McCarthy) Model; examining the main hypotheses of the study which is the measurement of the effect of exchange rate pass-through on price index; and partial hypotheses which discusses supply shock (oil prices) and demand shock (money supply) impact on price index.Using VAR model to examine these hypotheses, the results of variance components and impulse response revealed a strong relationship between the movement of foreign currencies exchange rates and the price index in Jordan; and the response of wholesale price index to these movements was greater than the response of consumer price index.The results as well showed a strong and positive effect of demand and supply shocks on the transfer of the movement of foreign currencies exchange rates to price index in Jordan. These effects were stable in first and second period and increased in the next periods. Level of exports concentration, imports composition, difference between domestic and global inflation rates, lack of flexibility of the wages and prices, capital movements, and markets integration; all these had a role in speeding the transfer of exchange rates movements to the price index in Jordan.

Development and Validation of RP-HPLC Method for the Simultaneous Determination of Trimethoprim, Sulfadimidine Sodiumand Tylosin Tartrate in injectable solution formulation

A simple, robust and reliable reversed phase HPLC method was developed and validated for the simultaneous determination of Trimethoprim (TMP), Sulfadimidine sodium (SDMS) and Tylosin tartrate (TYT) in Nuroprim® injectable solution formulation. The desired separation was achieved on XBridge C18 column (150 4.6 mm i.d., 5m) at room temperature. The optimized mobile phase consisted of a binary solvent mixture of acetonitrile and aqueous triethylamine (TEA) solution adjusted to pH 5.7 by acetic acid. The mobile phase flow rate was fixed at 1.0 ml/min and the analytes were monitored at 287 nm using photodiode array detector. The effects of the chromatographic conditions on peaks capacity factor, USP tailing factor, column efficiency and resolution were systematically optimized. The method was validated as per International Conference of Harmonization (ICH) and United States Pharmacopeia (USP) guidelines and found to be adequate for the routine quantitative determination of TMP, SDMS and TYT in commercially available Nuroprim® injectable solution dosage form.We would like to thanks Pharmacare pharmaceutical company (Palestine) for their continuous support

The Determinants of Banks' Credit Default at Jordanian Commercial Banks (Internal Perspective)

In this study researchers will examine the factors affecting the default of banks' credit facilities; the reasons behind the defaulting of the bank debts in Jordan, from the internal perspective, and to identify the early indicators appearance of the default of credit facilities. Through a random sample from Jordanian banks, throughout the year 2012. The research problem was specified to answer the following questions, firstly: What are the effect of (management efficiency, leverage, loan-loss provision, funding cost, and liquidity), factors at the default of credit facilities? Secondly: Which factors are considered to be important and should be monitored? The data will be analyzed by a use the linear regression to predict the relationship between the dependent variable (ratio of non-performing loans to total loans as at the end of financial year of bank i in time t) and the independents variables (management efficiency, leverage, loan-loss provision, funding cost, liquidity). In order to ensure that all regression assumptions are met, each variable will be tested for homoscedastic, linearity and normality. The results summaries show a negative relationship between the independents variables (management efficiency, loan-loss provision, funding cost, liquidity), and the dependent variable (ratio of non-performing loans to total loans. There is positive relationship between the independent variable (leverage), and dependent variable (ratio of non-performing loans to total loans. The R-squared figure (Explanatory Factor) equal to (0.935), this result is very high and emphasis the assumptions that researcher accept. Durbin–Watson value was (1.682) which indicates no autocorrelation. Researcher states the following recommendations: -               Banks have to give more attention to credit risk management to improve bank competitive advantage. -               Banks have to ease restrictions on borrowing process due to negative relation between liquidity and NLP, due to large amount of liquidity in Jordanian banks.
