The Impact of Aid on the Economic Growth of Developing Countries (LDCs) in Sub-Saharan Africa

Least Developed Countries (LDCs) of Sub-Saharan African have been recipients of official development assistance for more than 5 decades; however they are still characterized by chronic problems of poverty, low living standards and weak economic growth. The hot question is: Is aid effective in promoting economic growth? Thus, this paper investigates the impact of aid on the economic growth of 12 least developed countries in Sub-Saharan Africa over a period of 20 years. I take a fixed effects instrumental variable approach and the results imply that aid has a statistically insignificant negative impact on economic growth. I therefore conclude that aid is ineffective in promoting growth, perhaps due to misallocation of aid or inefficient use

Fearless: Maurice Phiri

As the class of 2017 joins Gettysburg College, we recognize first-year student, Maurice Wezi Phiri, who already has already showed his fearless commitment to social justice. [excerpt

Determination of the lift and drag characteristics of an airplane in flight

Flight tests to determine lift and drag characteristics are discussed. A review is given of the fundamental principles on which the tests are based and on the forces acting on an airplane in the various conditions of steady flight. Glide with and without propeller thrust and the relation between angle of attack and the indicated airspeed for different conditions of steady flight are discussed. The glide test procedure and the problem of the propeller are discussed

The Distribution of X-Ray Induced Crossovers from Curly Inversion Heterozygotes of Drosophila melanogaster Females

That crossing may occur in oogonial cells was suggested by the results of experiments by Whittinghill [1] in which crossing over was induced by x-rays in the X-chromosomes of Drosophila females homozygous for the c3G asynaptic factor. It had previously been demonstrated that induced crossovers recovered from Drosophila males were of spermatogonial origin [2,3]. Cooper's observations [4] of chiasmata in gonial cells of both sexes of Drosophila may provide cytological foundations for the hypothesis of gonial origin of some crossovers, particularly those which are x-ray induced. Somatic crossing over, the basis for the occurranece of twin spots in the hypodermis of Drosophilamales and females [5], closely parallels gonial crossing over in the formation of daughter cells which have become homozygous distally. The possible consequences of oogonial crossing over upon linking data, as recently discussed by Whittinghill [6], illustrate the need for further investigation of this phenomena. This paper reports the results of x-ray induced crossing over in Curly inversion heterozygotes of Drosophila melanogaster females, and these results are interpreted in relation to normal, or random, meiotic events as opposed to oogonial events of recombination

A direct procedure for interpolation on a structured curvilinear two-dimensional grid

A direct procedure is presented for locally bicubic interpolation on a structured, curvilinear, two-dimensional grid. The physical (Cartesian) space is transformed to a computational space in which the grid is uniform and rectangular by a generalized curvilinear coordinate transformation. Required partial derivative information is obtained by finite differences in the computational space. The partial derivatives in physical space are determined by repeated application of the chain rule for partial differentiation. A bilinear transformation is used to analytically transform the individual quadrilateral cells in physical space into unit squares. The interpolation is performed within each unit square using a piecewise bicubic spline

Mapping Sex Offender Addresses: The Utility of the Alaska Sex Offender Registry as a Research Data Base

The registration of sex offenders was part of a national effort to enhance public safety by permitting law enforcement officials to track the location of convicted sex offenders after their release. All fifty states have enacted legislation requiring persons convicted of various sex-related offenses to register with law enforcement agencies; many states also grant public access to all or a portion of their registries. This document reports on the Alaska Statistical Analysis Center's efforts to improve data accuracy in the Alaska Sex Offender Registry, maintained by the Alaska State Troopers, and to assess the registry's utility as a research tool.Bureau of Justice Statistics, Grant No. 1999-RU-RX-K006Background of the Project / Research Methodology / Results / Utility: Spatial Justice Research / APPENDICES / A.

The Exemption Laws of Washington

Remington\u27s Compiled Statutes for 1922, Section 563, specifies what property shall be exempt from execution and Section 703 specifies the amount of wages exempt from garnishment. This note will discuss these two exemption sections only and will not include the homestead law, which in a sense is itself an exemption law
