Modernization and the fertility transition, Egypt, 1975
This study investigates regional marital fertility differentials in Egypt and their relationship to the level of modernization of the region: defined as economic development and social and cultural change. The intermediate variables (Davis and Blake, 1965) underlying these regional levels and patterns of marital fertility are determined and their relation to the level of modernization of the region is also evaluated. In order to assess the nature of the recent decline in the crude birth rate in Egypt, the long term fertility and mortality levels are discussed. The prospects of a fertility transition in Egypt are assessed in terms of the current fertility level and pattern, the extent of deliberate fertility regulation, the urban-rural fertility differential and differentials by socioeconomic status.
The study draws from Easterlin\u27s model of social and economic determinants of marital fertility as a frame of reference. The model\u27s basic social and economic intermediate variables (denoted Cn, Cd, and CR)are evaluated, and the model\u27s interpretations of cross-sectional marital fertility differentials by socioeconomic status and the long term fertility trend are empirically verified
Making a Case for New Directions in English Language Teaching Research at an Omani University: A Critical Qualitative Content Analysis Report
Sultan Qaboos University (SQU) has been the sole English Language Teaching (ELT) research enterprise in the Sultanate of Oman through the Master of Education (M.Ed.) in Curriculum and Methods of Teaching English degree program it launched in the early 1990s. Eighty-two theses have been completed so far about topics pertinent to ELT in the Sultanate of Oman. However, a review of those theses has shown that the discussion of these topics lacks a critical dimension that can advance Omani ELT at the micro and macro levels. This critical qualitative study, therefore, sets out to make a case for new directions in ELT research at the M.Ed. in ELT program at SQU. The discussion should lead to better understanding of the multiple ELT problems in the Sultanate of Oman and have implications for other similar contexts
Spectral studies of some hydroxy-derivatives of anthraquinones
The u.v., visible, and i.r. spectra of several hydroxy-anthraquinones are discussed and the bands are assigned. These bands are compared with those of anthracene and anthraquinone. The band at 207 nm. is assigned to a n-sigma* transition; the bands at 252, 272, and 326 nm. are assigned by measuring spectra in solvents of various polarities. The stability constant for the 12-dihydroxyanthraquinone-ethanol complex is obtained
Misconduct resistance: the management of restricted drugs in the Western Australian public health service
We employ institutional theory to develop and present a framework – involving institutional drivers, organisational reactions, and outcomes – to examine and further understand misconduct resistance in public sector organisations. This framework is applied to an examination of efforts in the Western Australian public health service to prevent misconduct in the management of restricted drugs. We begin by clarifying a definition of misconduct resistance and then synthesise the extant literature develop a typology and framework of corruption resistance. The second part of the paper is a study in which the framework is applied to an examination of why and how the Western Australian public health service has endeavoured to prevent misconduct in the management of restricted drugs. Top-down imposition of regulations rather than shifts in individual employee attitudes is found. The paper concludes by outlining the potential contributions to theory and practice in approaches to increasing misconduct resistance in public health care organisations
Etapes et méthodes de formulation d’aliment de volaille : Une synthèse bibliographique
L’alimentation joue un rôle déterminant dans la réussite et la rentabilité économique des productions avicoles. Lors de la formulation d’un aliment efficient, son coût et sa qualité nutritionnelle qui permet de couvrir tous les besoins nutritionnels essentiels des volailles doivent être considérés. Ce travail basé sur la collecte des articles, fait la revue des étapes à suivre pour la formulation d’aliment de volaille et décrit les méthodes qui ont été utilisées dans la formulation d’aliment de volaille. Le carré de Pearson, l’équation algébrique simultanée, la méthode matérielle et la méthode essai et erreur sont des méthodes manuelles utilisées pour la formulation d’aliment de volaille. Les programmations linéaire, non linéaire, multi objective et quadratique sont quant à elles les méthodes de programmation mathématique de formulation d’aliment de volaille. Les méthodes manuelles permettent de faire une formulation avec peu d’ingrédient et les méthodes mathématiques permettent de faire une formulation à moindre coût.© 2015 International Formulae Group.

Impedance interaction between islanded parallel voltage source inverters and the distribution network
In an islanded microgrid consisting of parallel-connected inverters, the interaction between an inverter’s output impedance (dominated by the inverter’s filter and voltage controller) and the impedance of the distribution network (dominated by the other paralleled inverters’ output
impedances and the interconnecting power cables) might lead to instability. This paper studies this phenomenon using root locus analysis. A controller based on the second derivative of the output capacitor voltage is proposed to enhance the stability of the system. Matlab simulation results are presented to confirm the validity of the theoretical analysis and the robustness of the proposed controlle
