A preferred vision for administering secondary schools : a reflective essay
This reflective paper is my vision of the role of a forward looking Secondary Administrator who effectively uses educational research to impact school improvement in a positive fashion. It is, in effect, a snapshot that includes two sections. Some personal history, characteristics, and core values are in the first section. The final section is a composite reflection that synthesizes knowledge, skills, and attitudes gained through coursework and from experience into my professional vision for administrative practice. I think brain compatible computer-assisted learning can be a component of effective education and the research cited reflects that
A Policy Handbook for the Union Gap School District
This project presents a proposed policy handbook to the board of directors of the Union Gap School District which will replace the present outdated handbook. Prior to writing the new policies, a review was made of educational literature on policy development, the Union Gap School District\u27s board minutes, and surrounding school districts policy handbooks. The policies from the surrounding school districts were categorized according to subject matter, and, utilizing these policies along with a close communication with the school board and the superintendent, new policies were developed that would meet the unique needs of the Union Gap School District
The Relative Impact of External Capital on Manufacturing Output in Nigeria
External capital is one of the major sources of investible resources in most developing Countries and is made of foreign direct investment (FDI),foreign aid (AID) and external debt. In this study, the relative impact of external capital on manufacturing output, on one hand, and on Economic growth, on the other hand, in Nigeria, are examined. Economic growth is proxied by gross domestic product (GDP) growth. Employing the Ordinary Least Squares (OLS) method and an annual time series data for the period between 1982 and 2013 obtained from World Bank’s website, it is found that in the short-run, a 1 inflow of foreign aid is accompanied by a statistically significant 49 cents reduction in manufacturing output and a 1 inflow of FDI is accompanied by a statistically significant 1 inflow of aid is accompanied by a statistically insignificant 1 external loan inflow is accompanied by a statistically insignificant $1.73 increase in economic growth. This implies that FDI has a significant impact on economic growth, while AID and external debt has an insignificant or zero impact on economic growth. Therefore, not all forms of external capital do have significant impact on economic output in Nigeria. It is therefore recommended that government should make the business environment more investor friendly, make doing business in Nigeria easy, ensure prudent borrowing, ensure appropriate utilization of borrowed funds, ensure project continuity and ensure financial inclusiveness. Keywords: Foreign direct investment, foreign aid, external debt, manufacturing output, economic growth.
An Assessment of the Spatial and Temporal variations of Groundwater quality in Yatta Plateau in Kitui County, Kenya
The study is primarily focused on the assessment of groundwater quality in the Yatta Plateau of Kitui County. The study focused on the spatial temporal distribution of key chemical parameters namely pH, TDS, Colour, Total hardness, Turbidity, Conductivity, Total alkalinity, Fluoride and Iron. Groundwater samples were collected four times from the six target boreholes found on the plateau in the period between March 2015 and March 2016. The sampling programme covered two dry seasons and two wet seasons. Key physicochemical parameters were analysed using standard laboratory methods. The water samples were analyzed at the Water Resources Management Authority (WARMA) Water Quality Testing Laboratory in Nairobi. The results of the study show that there is no direct relationship between rainfall and variations of groundwater quality in the Yatta plateau. The influence of water abstraction on water quality was also limited. The dominant influence on groundwater quality in the Yatta Plateau was found to be the geological characteristics of the area. It was however found that there was spatial-temporal variability in different groundwater quality parameters that were analysed. The study recommends integrated groundwater resources management including continuous water quality monitoring in the Yatta Plateau in Eastern Kenya. Key Words: Groundwater quality, physic-chemical parameters, spatial-temporal variability, Yatta Plateau, Keny
Replacing Leads by Self-Energies Using Nonequilibrium Green's Functions
An open quantum system consists of leads connected to a device of interest.
Within the nonequilibrium Green's function technique, we examine the
replacement of leads by self-energies in continuum calculations. Our starting
point is a formulation of the problem for continuum systems by T.E. Feuchtwang.
In this approach there is considerable flexibility in the choice of unperturbed
Green's functions. We examine the consequences of this freedom on the treatment
of leads. For any choice the leads can be replaced by coupling self-energies
which are simple functions of energy. We find that the retarded self-energy
depends on the details of the choice of unperturbed Green's function, and can
take any value. However, the nonequilibrum self-energy or scattering function
can be taken to be independent of this choice. Expressed in terms of these
self-energies, nonequilibrium transport calculations take a particularly simple
form.Comment: 14 pages, 0 figure
A Review of Target Mass Corrections
With recent advances in the precision of inclusive lepton--nuclear scattering
experiments, it has become apparent that comparable improvements are needed in
the accuracy of the theoretical analysis tools. In particular, when extracting
parton distribution functions in the large-x region, it is crucial to correct
the data for effects associated with the nonzero mass of the target. We present
here a comprehensive review of these target mass corrections (TMC) to structure
functions data, summarizing the relevant formulas for TMCs in electromagnetic
and weak processes. We include a full analysis of both hadronic and partonic
masses, and trace how these effects appear in the operator product expansion
and the factorized parton model formalism, as well as their limitations when
applied to data in the x->1 limit. We evaluate the numerical effects of TMCs on
various structure functions, and compare fits to data with and without these
corrections.Comment: 41 pages, 13 figures; minor updates to match published versio
