Abstract

The main aim in this study is to explain the effect of natural resource endowment or ‘oil wealth’ on the Libyan economy and, more importantly, explore how Libya can take advantage of this resource whilst avoiding the Dutch disease problem. In order to do this, the study has three objectives:-

1.     To identify what variables are of importance in the economic growth in particular of oil producing countries, and what is the impact of oil on those variables.

2.     To identify the most important growth strategies that oil-rich countries are following.

3.     To identify the nature of the relationship between oil revenue and realizing permanent economic development in Libya, while identifying the most potentially beneficial economic development policies that could be adopted in Libya in terms of the participation of economic sectors, investment priorities, and encouragement of economic diversification.

Multiple methods were used to collect data in this research through information gathered from existing literature - data for a wide study of 74 oil producing countries, case studies on a number of oil rich comparator countries, as well as a qualitative analysis of the Libyan economy itself with data derived from semi-structured interviews and a focus group.

Preliminary results indicate that the abundance of oil wealth has a positive direct relationship on GDP; however economic growth is obstructed indirectly by oil wealth through the effect of some other economic variables within the model. For instance, an abundance of oil wealth negatively (statistically significantly) affects manufacturing, public spending on education and the entry of foreign direct investment; however, there is a positive (statistically not significant) relationship between oil wealth and each of agriculture value added and Sovereign Wealth Funds (SWF). There is however a negative (statistically significant) relationship between SWF and GDP as well as a positive, statistically significant, relationship between the following variables: manufacturing value added, agriculture value added, and Foreign Direct Investment with GDP. The relationship is positive, but statistically not significant, between public spending on education and GDP.

In terms of the case study countries discussed, it can be recognized that different growth strategies have been adopted to reach economic diversification; in general all countries have increased their investment in education for all stages, in supporting the tourism sector and those manufacturing industries that link to oil and gas. However, the contribution of the agricultural sector to GDP for some oil-rich countries has diminished, even in those countries which have increased their efforts to support that sector. The main challenge facing those countries in terms of attracting more foreign direct investment is political and security stability. Countries consider SWF as an important way to diversify the economy, to achieve sustainable growth and to maximize profits.

In the specific context of Libya, this study reveals that it is facing a political Dutch disease as well an economic Dutch disease. Because of the size of the public sector, private sector activities were crowded out because of the ability of the government to dominate the economy through its large oil revenues. It is therefore a type of Dutch disease with a different scenario.

As an evaluation method for e-Government world wide web portal in Turkey cities, I have applied and proposed an evaluation method to measure the accuracy for the usability satisfaction. By calculating the population for each city, I have selected the government website and try to apply the error checking by depending on the Measure 1. Measure 1 which has 10 dichotomous web usability standard, I valuate and coded each site based on the 10 dichotomous usability standards. Those dichotomous are categories and based on Web design errors, Standard web design

conventions, and the Presence of features designed. Then I suggest a method to easure the usability satisfaction by computing the total average for each site after I compute the individual average by counting the number of ones during our usability checking using Measure 1. Then I have found that the total number of websites that have satisfied the usability majority is (39 webpage) which is an approximate equal to

48%, and the sites that does not satisfy the usability majority is (42 webpage), which about 51%. Moreover, I tried to study the relation between the final usability accuracy that related to each dichotomous usability standards.

In my Experimental results and by plotting each usability satisfaction, I tried to find the dichotomous that effect on the final usability accuracy for each Turkey cities sites such as splash page which is named V1 in my experimental result and V2 which

is the need for horizontal scrolling at 1024×768 resolution or below those dichotomoushave achieved (100%) for the usability success. In contrast, Turkey website usability succeed has been affected by some Measure 1 dichotomous, which have achieved (0%) such as V4 which is the underlined text links which effect on the have achieved (0%) such as V4 which is the underlined text links which effect on the

user ability accuracy as a final measurement result.

The ethics of financial reporting assumes a center stage in the corporate world in the background of an emerging understanding of corporate social responsibility (CSR). We review the literature on the link between earnings management (EM) and CSR and reveal that there are two contradictory perspectives. One perspective assumes that EM is negatively associated to CSR, while the other argues that EM and CSR are positively related. These perspectives are based on the competitive existence theories such as agency, singling, stakeholder, legitimacy theories. While, the negative relationship between EM and CSR perspective is in line with the legitimacy, agency and singling theories, the positive relationship is in accordance with stakeholder theory.

The present work reports a facile approach to the one-pot solution growth of vertically

aligned, doped ZnO nanorod (NR) arrays by chemical bath deposition (CBD). The effects of

dopant ions on the final morphologies, electronic band structures and donor densities of

ZnO NRs were examined. With the introduction of dopants, the optical band gap energies

of the samples were reduced. The photoelectrochemical (PEC) water splitting performances

of the doped ZnO NRs were tested. When compared with pristine ZnO NRs, the doped ZnO

NRs demonstrated an improvement of at least 15% in the PEC water splitting activity. Nadoped ZnO NRs was the most efficient photoanode, where its photocurrent density was 2.1

times greater than that of pristine ZnO NRs. The mechanism for improved PEC performance was proposed

The Great Man-Made River (GMR) is the world largest irrigation project, consisting of a network of pipes that supplies water from Libyan desert in the south to the coastal areas in the north. This paper studies the possibility of taking advantage of GMR to generate energy and produce food through agriculture. Hydro-kinetic power generation, would be carried out by generating energy from water movements across Great Man-Made River pipelines using appropriate sizes of turbines. It’s known that the length of the GMR pipeline is about 4000 km with a diameter of 4 m. Pipeline of such magnitude with great water flow rate would make a turbine to produce hundreds of Kilowatts of clean energy. The most significant reasons that force us to take advantage of GMR to generate energy are: a) The needs to sustainable environmental energy source; b) Power System uses energy of flowing water to provide a consistent, controllable, non-weather-dependent source of electricity, such as other types of renewable energy, which are depend on the weather. The conversion of GMR, from supplying freshwater to coastal cities, to huge agricultural project after the establishment of many seawater desalination plants (solar powered) would cover the needs of cities for fresh water. Thus it would become possible to convert thousands of desert hectares around the pipelines to huge agricultural project irrigated from GMR.

We performed a comprehensive study of trichomes considering the medicinal importance of the essential oils produced in glandular trichomes of Salvia aegyptiaca L. and lack of data about leaf trichome characteristics. Micromorphological and histochemical analyses of the trichomes of S. aegyptiaca were carried out using light and scanning electron microscopy. We report that the leaves contained abundant non-glandular unbranched trichomes and two types of glandular trichomes, peltate and capitate, on both leaf surfaces. The abaxial leaf side was covered with numerous peltate and capitate trichomes, while capitate trichomes were more abundant on the adaxial leaf side, where peltate trichomes were rarely observed. The non-glandular trichomes were unicellular papillae and multicellular, uniseriate, two-to-six-celled, erect or slightly leaning toward the epidermis. Peltate trichomes were composed of a basal cell, a short cylindrical stalk cell and a broad head of eight secretory cells arranged in a single circle. Capitate trichomes consisted of a one-celled glandular head, subtended by a stalk of variable length, and classified into two types: Capitate trichomes type I (or short-stalked glandular trichomes) and capitate trichomes type II (or long-stalked glandular trichomes). Histochemical tests showed that the secreted material in all types of S. aegyptiaca glandular trichomes was of a complex nature. Positive reactions to lipids for both types of glandular trichomes were obtained, with especially abundant secretion observed in peltate and capitate trichomes type II.
