Youth Livelihood Opportunities In Egypt, Safaa El-Kogali, Nagah Hassan Al Bassusi Jan 2001

Youth Livelihood Opportunities In Egypt, Safaa El-Kogali, Nagah Hassan Al Bassusi

Poverty, Gender, and Youth

This report presents results from a quantitative and qualitative study on youth livelihood opportunities in Egypt. The study was motivated by growing evidence of increasing unemployment among the young at a time when new entrants into the labor force are also increasing at unprecedented rates. Egypt has a youth population of over 13 million aged 15–24—over a fifth of the total population. They constitute the largest segment of the economically active population. Whether this bulge of young workers entering the labor force is a “demographic gift” or a “demographic burden” depends in large measure on the policies that are in …

Facts About Adolescents From The Demographic And Health Survey—Statistical Tables For Program Planning: Central African Republic 1994–1995, Population Council Jan 2001

Facts About Adolescents From The Demographic And Health Survey—Statistical Tables For Program Planning: Central African Republic 1994–1995, Population Council

Poverty, Gender, and Youth

The Population Council initiated its work on adolescents in the mid-1990s. At that time, those advocating greater attention to adolescent issues were concerned about adolescent fertility—particularly outside of marriage—and adolescent “risk-taking” behavior. As an international scientific organization with its mandate centered around the needs of developing countries, the Council sought a more nuanced and context-specific understanding of the problems confronting adolescents in the developing world. In working with colleagues inside and outside the Council, it became clear that information on adolescents, and the way data are organized, were limiting the ability to understand the diversity of their experiences or to …

"Under The Umbrella Of Black Civilization": A Conversation With Reginald Mcknight, Bertram D. Ashe Jan 2001

"Under The Umbrella Of Black Civilization": A Conversation With Reginald Mcknight, Bertram D. Ashe

English Faculty Publications

Talking to Reginald McKnight is like scanning an imaginary worldwide radio dial. At any given moment he can transform his pleasant speaking voice into a raspy, aged, Middle Eastern-by-way-of-New York accent - or a deep Southern drawl. In an instant he can switch from a precise West African dialect to hip, urban street lingo, and then effortlessly segue back to his normal voice. McKnight says he "hit the ground running" as a mimic, and his talent was broadened as he lived all over the United States as the son of an Air Force sergeant. His time spent on the road …

Studying The Relationship Between Parental Involvement And Sternberg's Triarchic Theory Of Intelligence, Liliana Munoz Bailey Jan 2001

Studying The Relationship Between Parental Involvement And Sternberg's Triarchic Theory Of Intelligence, Liliana Munoz Bailey

HIM 1990-2015

Extensive research has been conducted in the area of intelligence. Most of the research in this area has been focused on cognitive abilities. However, little research has been explored other type of intelligence and the environmental factors. The intent of this study was to investigate Sternberg’s Theory of Intelligence and parental involvement. According to this theory an individual’s intelligence is composed of three main domains: cognitive, creative and practical. Every individual possesses these abilities to a greater or lesser degree. Yet, little is known of what factors could lead to the difference in these types of abilities in individuals. Parental …

Prostasin Is A Glycosylphosphatidylinositol-Anchored Active Serine Protease, Li-Mei Chen, Melanie L. Skinner, Steven W. Kauffman, Julie Chao, Lee Chao, Catherine D. Thaler, Karl X. Chai Jan 2001

Prostasin Is A Glycosylphosphatidylinositol-Anchored Active Serine Protease, Li-Mei Chen, Melanie L. Skinner, Steven W. Kauffman, Julie Chao, Lee Chao, Catherine D. Thaler, Karl X. Chai

Faculty Bibliography 2000s

A recombinant human prostasin serine protease was expressed in several human cell lines. Subcellular fractionation showed that this serine protease is synthesized as a membrane-bound protein while a free-form prostasin is secreted into the culture medium, Prostasin was identified in nuclear and membrane fractions. Membrane-bound prostasin can be released by phosphatidylinositol-specific phospholipase C treatment, or labeled by [H-3]ethanolamine, indicating a glycosylphosphatidylinositol anchorage. A prostasin-binding protein was identified in mouse and human seminal vesicle fluid. Both the secreted and the membrane-bound prostasin were able to form a covalently linked 82-kDa complex when incubated with seminal vesicle fluid. The complex formation between …

The Marsokhod rover returned data from six stations that were used to decipher the geomorphology and geology of a region not previously visited by members of the geomorphology field team. Satellite images and simulated descent images provided information about the regional setting. The landing zone was on an alluvial apron flanking a mountain block to the west and a playa surface to the east. Rover color images, infrared spectra analysis of the mountains, and the apron surface provided insight into the rock composition of the nearby mountains. From the return data the geomorphology team interpreted the region to consist of …

Faculty Bibliography 2000s

Paleotopographic reconstructions based on a synthesis of published geologic information and high-resolution topography, including topographic profiles, reveal the potential existence of an enormous drainage basin/aquifer system in the eastern part of the Tharsis region during the Noachian Period. Large topographic highs formed the margin of the gigantic drainage basin. Subsequently, lavas, sediments, and volatiles partly infilled the basin, resulting in an enormous and productive regional aquifer. The stacked sequences of water-bearing strata were then deformed locally and, in places, exposed by magmatic-driven uplifts, tectonic deformation, and erosion. This basin model provides a potential source of water necessary to carve the …

Faculty Bibliography 2000s

A systematic investigation of the diffusion of Be, B, Na, Mg, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Zn, Ge, Rb, and Mo in silicon has been carried out. The elements were implanted into silicon wafers as low dose impurities, and then postheat treatments of the ion-implanted samples were conducted at different temperatures for a specific time. Following the anneals, the depth profiles were obtained by secondary ion mass spectrometry analyses. A wide range of diffusion behavior has been observed for these elements. Based on differences in the depth profiles the diffusion mechanism was identified where possible. (C) …

Faculty Bibliography 2000s

On April 15 and 19, 1998, two intense dust storms were generated over the Gobi desert by springtime low-pressure systems descending from the northwest. The windblown dust was detected and its evolution followed by its yellow color on SeaWiFS satellite images, routine surface-based monitoring, and through serendipitous observations. The April 15 dust cloud was recirculating, and it was removed by a precipitating weather system over east Asia. The April 19 dust cloud crossed the Pacific Ocean in 5 days, subsided to the surface along the mountain ranges between British Columbia and California, and impacted severely the optical and the concentration …

Faculty Bibliography 2000s

The use of focused ion beam (FIB) instruments for device modification and specimen preparation has become a mainstay in the microelectronics industry and in thin film characterization. The role of the FIB as a tool to rapidly prepare high quality transmission electron microscopy specimens is particularly significant. Special attention has been given to FIB milling of Cu and Si in the microelectronics arena. Although FIB applications involving Si have been extremely successful, it has been noted that Cu tends to present significant challenges to FIB milling because of effects such as the development of milling induced topographical features. We show …

Effect Of Spin-Orbit Interaction In Photoionization Of Bromine, H. P. Saha, Dong Lin Jan 2001

Effect Of Spin-Orbit Interaction In Photoionization Of Bromine, H. P. Saha, Dong Lin

Faculty Bibliography 2000s

The partial and total photoionization cross sections from the initial P-2(3/2) ground state of atomic Br to the final Br+ P-3(1) components across the 4p(4)(D-1(2))6d,8s(P-2, D-2, F-2, S-2) autoionization resonances are presented. The multiconfiguration Hartree-Fock (MCHF) method has been used to calculate both bound and continuum wave functions in the nonrelativistic limit. The Breit-Pauli approximation is applied to determine the effect of spin-orbit interactions in the photoionization of atomic Br with the MCHF wave function as input. Our calculated results are compared with experimental data.

Morphological Operations On Color Images, Lloyd J. Sartor, Arthur R. Weeks Jan 2001

Morphological Operations On Color Images, Lloyd J. Sartor, Arthur R. Weeks

Faculty Bibliography 2000s

Morphological image processing has been widely used to process binary and grayscale images, with morphological techniques being applied to noise reduction, image enhancement, and feature detection. Relying on an ordering of the data, morphology modifies the geometrical aspects of an image: object contours in binary images and object surfaces in grayscale images. Extending morphological operators to color image processing has been problematic because it is not easy to define geometry of a vector-valued function and ordering of vectors is not straightforward We propose a new set of color morphological operators based on a combination of reduced ordering and conditional ordering …

Nanoscale P-N Junction Fabrication In Silicon Due To Controlled Dopant Electromigration, Leonid Chernyak, Mikhail Klimov Jan 2001

Nanoscale P-N Junction Fabrication In Silicon Due To Controlled Dopant Electromigration, Leonid Chernyak, Mikhail Klimov

Faculty Bibliography 2000s

An external electric field (up to 10(6) V/cm) was used for nanoscale p-n junction fabrication in Si doped with Li (Si:Li) in situ in a scanning probe microscope. Creation of nano-p-n junctions was ascribed to the thermally assisted electromigration of Li+ ions. Tunneling I-V spectroscopy provided evidence for a conversion of the electrical conductivity type from p to n. A local temperature increase during an electric field-induced p-n junction fabrication was estimated to be up to 160 degreesC.

Mathematical Model For The Irradiance Probability Density Function Of A Laser Beam Propagating Through Turbulent Media, M. A. Al-Habash, L. C. Andrews, R. L. Phillips Jan 2001

Mathematical Model For The Irradiance Probability Density Function Of A Laser Beam Propagating Through Turbulent Media, M. A. Al-Habash, L. C. Andrews, R. L. Phillips

Faculty Bibliography 2000s

We develop a model for the probability density function (pdf) of the irradiance fluctuations of an optical wave propagating through a turbulent medium. The model is a two-parameter distribution that is based on a doubly stochastic theory of scintillation that assumes that small-scale irradiance fluctuations are modulated by large-scale irradiance fluctuations of the propagating wave, both governed by independent gamma distributions. The resulting irradiance pdf takes the form of a generalized K distribution that we term the gamma-gamma distribution. The two parameters of the gamma-gamma pdf are determined using a recently published theory of scintillation, using only values of the …

Variations In The Onset Diameter For Martian Layered Ejecta Morphologies And Their Implications For Subsurface Volatile Reservoirs, Nadine G. Barlow, John Koroshetz, James M. Dohm Jan 2001

Variations In The Onset Diameter For Martian Layered Ejecta Morphologies And Their Implications For Subsurface Volatile Reservoirs, Nadine G. Barlow, John Koroshetz, James M. Dohm

Faculty Bibliography 2000s

We investigated regional variations in the onset diameter of craters displaying a single layer ejecta morphology within +/- 30 degrees latitude using Viking imagery. Our results generally agree with those of previous studies which show onset diameters of 5 to 6 km in the equatorial region, but we have identified localized regions with unusually small onset diameters. The largest region is located in Solis and Thaumasia Planae. The 3-5 km onset diameter range in this area indicates a near-surface ice-rich reservoir (depth similar to 110 m). This unusual concentration of near-surface ice may have resulted from magmatic-driven uplifts associated with …

Strategic Interdependence In Organizations: Deconglomeration And Marketing Strategy, P. Rajan Varadarjan, Satish Jayachandran, J. Chris White Jan 2001

Strategic Interdependence In Organizations: Deconglomeration And Marketing Strategy, P. Rajan Varadarjan, Satish Jayachandran, J. Chris White

Faculty Bibliography 2000s

Although strategy exists at multiple levels in a firm (corporate, business, and functional), there is a dearth of research in marketing literature that focuses on the dependency among strategy at different levels. The authors address this issue by examining the relationship between deconglomeration and marketing strategy. Deconglomeration refers to the divestiture behavior of a conglomerate firm and the transformation of its business portfolio from one that is largely composed of several unrelated businesses to one composed of fewer and related businesses. Drawing on multiple theoretical perspectives, the authors propose a conceptual model delineating the environmental and organizational drivers of deconglomeration …

Practical Experience Using A Computational Model For The Design Of Heterogeneous Distributed Software, T. L. Williams, R. J. Parsons Jan 2001

Practical Experience Using A Computational Model For The Design Of Heterogeneous Distributed Software, T. L. Williams, R. J. Parsons

Faculty Bibliography 2000s

Heterogeneous cluster environments are becoming an increasing popular platform for executing parallel applications. Efficient heterogeneous programs must account for the differences inherent in such an environment. We propose the HBSP(1) model of computation as a framework for developing applications for heterogeneous clusters of workstations. The utility of the model is demonstrated through the design and analysis of the scatter and one-to-all broadcast algorithms. Extensive experimentation illustrates the benefits of using the model for heterogeneous program development. By hiding the non-uniformity of the underlying system, the HBSP(1) model provides a framework that embraces the heterogeneity of the underlying system.
