Desempleo e informalidad en América Latina: Definiendo políticas públicas para Venezuela
Osta Trestini,Karelys Mercedes;
Revista Venezolana de Gerencia , 2007,
Abstract: abstract this article presents a general view of unemployment and informal economy in latin america, and their evolution en argentina, brazil, chile and venezuela, between 1990 and 2004. the study includes the policies and programs related to this matter, using documentary, descriptive research. what was learned through the experiences of these countries served as a basis for defining public policies for venezuela, directed to providing human and financial capital for the unemployed, workers and employers in the informal economy that would allow them to have access to jobs and the creation of their own micro or small businesses with greater productivity and added value, counting on the support of an adequate legal framework and an institutionality capable of giving an effective, efficient and opportune response to their needs
Desempleo e informalidad en América Latina: Definiendo políticas públicas para Venezuela
Karelys Mercedes Osta Trestini
Revista Venezolana de Gerencia , 2007,
Abstract: En este artículo se presenta una visión general del desempleo y la economía informal en América Latina, así como de su evolución en Argentina, Brasil, Chile, y Venezuela durante el período comprendido entre 1990 y 2004, incluyendo las políticas y programas relacionados con esta materia, a través de una investigación descriptiva de tipo documental. Finalmente, el aprovechamiento de los aprendizajes de la experiencia de estos países sirvió de base para la definición de políticas públicas para Venezuela dirigidas a proveer de capital humano y financiero a desempleados, trabajadores y empleadores de la economía informal que les permita tener acceso a oficios y a lacreación de sus micro o peque as empresas con mayor productividad y valor agregado, contando con el respaldo de un marco legal adecuado y una institucionalidad capaz de dar respuesta eficaz, eficiente y oportuna a sus necesidades
Relationships between Hydraulic Parameters of the Nubian Aquifer and Wells in El Shab Area, South Western Desert, Egypt (A Case Study)  [PDF]

International Journal of Geosciences (IJG) , 2012, DOI: 10.4236/ijg.2012.35112
Abstract: For proper water management in the new reclaimed areas, hydraulic parameters of both aquifer and wells related to transmissivity, specific capacity, well loss, formation loss, and water entrance velocity, as well as the relationship between these parameters are the main target after construction of production wells. In El Shab area, the Nubian Sandstone aquifer has a large range of transmissivity (from 483.12 to 1489.24 m2/day) and, also, specific capacity (from 203 to 486.32 m2/day). Relationship of specific capacity and transmissivity is constructed and the established empirical equations can be used to predict the transmissivity of the Nubian aquifer in all new proposed sites for well drilling at which the specific capacity measured without performing pumping tests. On the other hand, the drilled wells in El Shab area exhibit relatively high well losses (25%). The causes for high well losses (entrance velocity (Vn) through water well screen and the distance from the point of water entrance in the well to the point of intake in the pump) are discussed and the relationships are constructed, which seem a positive linear correlation. Relationships between well losses constant for 30 wells with transmissivity and specific capacity, are constructed. These relationships are useful for estimating hydraulic characteristics that are needed for the designs of wells and well fields and for preliminary water-resources management.
An Index of Socio-Economic Well-Being of U.S. Farm Households  [PDF]
Hisham S. El-Osta
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.512104
Abstract: The primary purpose of the paper is to construct a combined index of quality-of-life and economic wellbeing based on national data from the 2004 Agricultural Resource Management Survey. Additional objective is to assess the role of increased utilization of various types of Federal farm programs in the context of the life-cycle on socioeconomic wellbeing. A central finding, which has implication for rural development and the continuity of the family farm, shows a positive relationship between increased intensity of farm program participation and higher likelihoods of socioeconomic wellbeing, particularly among elderly farmers.
Intensity of Off-Farm Employment and Its Impact on Wage Distribution: Does the Source of Health Insurance Coverage Matter?  [PDF]
Hisham S. El-Osta
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.76116
Abstract: The determinants of off-farm wages, with emphasis on the role of working full-time off the farm, are examined using data from the 2015 Agricultural Resource Management Survey and quantile regression. The targeted groups of farm operators for the analysis are based on whether health insurance coverage is obtained from the off-farm employer, and whether it is obtained from other sources. Findings indicate a negative association between full-time off-farm work and off-farm wages among farm operators in both categories who are at the higher portions of their respective off-farm wage distributions, which is in accordance with the compensating differential prediction.
Description et usages d’un nouveau dispositif de vidéo-cours : l’encre numérique
Marc Trestini,Eric Christoffel,Isabelle Rossini
Questions Vives : Recherches en éducation , 2011, DOI: 10.4000/questionsvives.656
Abstract: Cet article présente un nouveau design de vidéo-cours pour l’enseignement universitaire : l’encre numérique . Il rend compte de son impact sur l’apprentissage et décrit le profil cognitif des étudiants pour qui ce dispositif semble produire les meilleurs résultats. Le dispositif étudié est constitué d’un Tablet PC associé à un cahier de textes en ligne. Le Tablet PC permet de vidéoprojeter ce que l’enseignant avait coutume d’écrire auparavant au tableau et le cahier de textes de restituer, en ligne, l’ensemble des traces du cours (visuelles, sonores, textuelles). L’étude du dispositif s’appuie sur les résultats des étudiants aux examens, la fréquence de consultation des ressources, ainsi que sur la manière dont elles sont consultées. Cette étude met en évidence certaines caractéristiques et affordances du dispositif qui semblent avoir un effet bénéfique sur les apprentissages et ce, en fonction du profil cognitif de l’étudiant. This paper presents a new design of video courses for university teaching. It is called "digital ink". It shows its impact on student learning and describes the cognitive profile of students for which this device seems to produce the best results. The device which is studied consists of a Tablet PC combined with a work agenda on line. The Tablet PC enables one to project what the teacher traditionally wrote on the board. That is to say; explanatory notes, equations and hand-written diagrams. The teacher has a writing tool (digital light pen) which allows cursive script (handwriting) on a computer. All written records produced by the teacher during the course, accompanied by verbal comments are recorded. The study of this device is based on student performance on exams, how often they consulted the videos as well as the manner of consulting them. This study shows the impact of this new device on student learning according to their cognitive profile.
The e ects of ownership structure on corporate value in the Tehran Stock Exchange (TSE)
Sohrab Osta,Hossein Naderi
Management Science Letters , 2012,
Abstract: In the present study, the separate and simultaneous role of concentration and type of ownership on corporate value is investigated. In this study, the ownership structure is classi ed into four classes: the institutional ownership, the corporate ownership, the management ownership and the foreign ownership. In addition, di erent attitudes regarding the above ownership are also tested, that is, active monitoring hypothesis and interest convergence hypothesis. Since, in the sample research no information was found about foreign ownership, this type of ownership was not examined. However, in the case of the other ownerships, a separated hypothesis was developed based on various techniques and their in uence on the corporate value was examined. For each hypothesis, a multiple linear regression model is de ned based on the dependent variables. Companies listed in securities exchange commission of Iran makes up the statistical community of present study and the sample consists of 90 companies during 2002-2008. Two types of tests, including correlation test and cross multiple regression test are implemented to examine the hypothesis. Generally, the results reflect no signi cant relationship between the concentration of ownership and the corporate value. The results of the study show that, while there is no relationship between the institutional ownership and management ownership and the corporate value, there is a signi cant relationship between the corporate ownership and the corporate value.
