Real Exchange Rate Misalignment and Economic Growth: An Empirical Study for the Maghreb Countries
Zouheir Abida
International Journal of Economics and Finance , 2011, DOI: 10.5539/ijef.v3n3p190
Abstract: It has long been recognized in academic and policy debates that domestic policies play an important role in explaining economic growth. The paper investigates the role of real exchange rate (RER) misalignment on long-run growth in three countries of the Maghreb countries (Tunisia, Algeria and Morocco) over the period 1980-2008. We first estimate equilibrium RER relying on the Fundamental Equilibrium Exchange Rate (FEER) approach, from which misalignment is derived. Second, we estimate a dynamic panel growth model in which among the traditional determinants of growth, our measure of misalignment is included. The results indicate that the coefficient for RER misalignment is negative, which means that a more depreciated (appreciated) RER helps (harms) long-run growth. As a consequence, an appropriate exchange rate policy would close the gap between RER and its equilibrium level.
Economic Growth and Income Inequality: Empirical Evidence from North African Countries
Zouheir ABIDA,Imen Mohamed SGHAIER
Asian Economic and Financial Review , 2012,
Abstract: This paper examines the empirical relationship between economic growth and income inequality for 3 countries of North Africa (Tunisia, Morocco and Egypt) over the period 1970-2004. The results of this paper indicate that the long-run growth elasticity of income inequality is negative and significant implying that keeping other factors constant; more income inequality reduces economic growth. Moreover, this paper finds evidence that more physical and human capital investment and higher openness to trade have statistically significant impact on enhancing economic growth and reducing poverty.
Structural and Dielectric Properties of Sintering Zinc Oxide Bulk Ceramic  [PDF]
Mariem Chaari, Adel Matoussi, Zouheir Fakhfakh
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.27105
Abstract: Undoped zinc oxide (ZnO) has been prepared at various growth temperatures by conventional sintering process. The morphology and crystalline properties of ZnO pellets were examined by scanning electron microscopy, atomic force microscopy and X-ray diffraction. It has revealed that the grain size and surface roughness tends to increase by increasing the sintering temperature. XRD analysis showed that all samples are polycrystalline with a hexagonal wurtzite structure. The alignment of ZnO grains along the (10.0) plane was enhanced as the temperature increased. Interestingly, the compressive stress was found to decrease drastically from –0.62 GPa at 700°C to –0.2 MPa at 1000°C. This improvement in film structure seems to enhance considerably the dielectric properties for the samples sintering at high temperatures. Results show an increase of dielectric constant and a decrease of electrical resistivity when increasing the sintering temperature.
The Regional Integration Agreements: A New Face of Protectionism
Montej Abida
International Journal of Economics and Finance , 2013, DOI: 10.5539/ijef.v5n3p183
Abstract: The regional integration agreements can be a strategy of trade diversion and thus we can say that there is a violation of the rules of free trade. By creating preferential rules which are inconsistent with the principles of the WTO, the strategy of regional integration can increase the risk of trade disputes with third party countries and can therefore generate a commercial environment full of threats and reprisals. Third countries, especially developing countries have small markets, may find themselves marginalized further when the members of the regional group adopt the principle of discrimination. The philosophy of the WTO paves the way for a transition from regional integration towards a multilateral integration. The question that arises is whether regional integration agreements meet this conception of the WTO or they represent a new form of protectionism hindering free trade. We know that the regional groups hold private information about the actions and decisions they adopt in the intra-group. The uncertainty and hidden information can cause conflicts internationally. The WTO, we can assume as the Principal, should create incentives that can guide regional groups that can be assumed as Peripheral Agents, to comply with Article XXIV and the elimination of regional protectionism. Control actions and trade policies of regional groups should be done on a regular basis to make the game of international trade more fair.

Abstract: OBJECTIVES: To assess the knowledge, attitude and practice of people about malaria in a semiurban area near Rawalpindi and Islamabad. DESIGN: Descriptive Cross Sectional Study.SETTING: A cross sectional survey was conducted in a semi urban area of model village Humaknear Rawalpindi and Islamabad. METHOD: Universal questionnaire was used to assess theknowledge, attitude and practices about malaria. The head of family (Male or Female) was interviewed bystructured Questionnaire. RESULTS: In 85% of respondents opinion malaria is a dangerous disease and97% were in favor of protective measures against malaria. Regarding the protective measures 56% were infavor of mosquito net. By the use of mosquito net or repellent 98% of respondents attitude was preventionagainst the mosquito bite. 93% respondents answered that they would like to know about details of malariaproblem. Regarding the practices 72% of respondents, family members suffered from malaria during thepast. 70% of respondents, recognized the malaria on their own by recognizing signs and symptoms ofmalaria, and doctor diagnosed 5%. 70% were planning protection from mosquito bite and 5% were doingself-medication. During malaria season 32% were taking Chemoprophylaxis. 66% were planning tosafeguard their family from mosquito bite and 40% were using mosquito nets. 30% of respondents wereusing mosquito repellents when they were going out of home. Those who were using chemical mat 68%were using regularly and 32% were occasional user. CONCLUSION: The study explores that there is needfor more accurate knowledge transmission from media and health workers and effective health educationprograms and energetic malaria control and eradication steps.

Probability distribution of flood flows in Tunisia
H. Abida ,M. Ellouze
Hydrology and Earth System Sciences (HESS) & Discussions (HESSD) , 2008,
Abstract: L (Linear) moments are used in identifying regional flood frequency distributions for different zones Tunisia wide. 1134 site-years of annual maximum stream flow data from a total of 42 stations with an average record length of 27 years are considered. The country is divided into two homogeneous regions (northern and central/southern Tunisia) using a heterogeneity measure, based on the spread of the sample L-moments among the sites in a given region. Then, selection of the corresponding distribution is achieved through goodness-of-fit comparisons in L-moment diagrams and verified using an L moment based regional test that compares observed to theoretical values of L-skewness and L-kurtosis for various candidate distributions. The distributions used, which represent five of the most frequently used distributions in the analysis of hydrologic extreme variables are: (i) Generalized Extreme Value (GEV), (ii) Pearson Type III (P3), (iii) Generalized Logistic (GLO), (iv) Generalized Normal (GN), and (v) Generalized Pareto (GPA) distributions. Spatial trends, with respect to the best-fit flood frequency distribution, are distinguished: Northern Tunisia was shown to be represented by the GNO distribution while the GNO and GEV distributions give the best fit in central/southern Tunisia.
Soil Fertility Problems in Cetnral Rechna Doab
Muhammad Arshad,Abida Akram
Pakistan Journal of Biological Sciences , 1999,
Abstract: The study was conducted to evaluate the fertility status of soil in the central Rechna Doab area. Fertility of the whole Central Rechna Doab area was low, Phosphorus in particular was low in all soils, and some soil samples were Potassium deficient while few were low in nitrogen. The situation can be brought to medium fertility level by using proper amount of NPK on the basis of soil test evaluation. However, a high fertility level can only be achieved by all round efforts on scientific basis.

Abida Nasreen,Ghulam Mustafa
Pakistan Journal of Biological Sciences , 2000,
Abstract: Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) completed its larval stage in 17.325±0.326 days passing through six instars under laboratory protocol, 26±1 °C, 60-70% RH and 16 hours` daylight. The larvae moulted for 2nd instar, two days after hatching from eggs. Average stadiel periods for 2nd, 3rd, 4th, 5th, and 6th instars were 2.07, 2.15, 2.48, 3.12, 3.55 and 3.95 days respectively. The last larval stage did not moult but was contracted and shortened into grub like pre-pupal stage. The average length measured for each instar (first to sixth) was 3.4, 4.6, 9.7, 17, 28.35, 36.85 mm respectively. The average pupal period was 13.2 days for female and 15.4 days for male. Fecundity of moths fed on sucrose solution was significantly higher than water fed females. The unfed females laid few eggs none was viable.
