An Alternative Residential Education Program: An Evaluative Study

Schools today are trying to make an adaptation to accommodate all children and their disabilities. For many, the problem does not lie in a child\u27s learning ability, but rather in their behavioral disability. According to its mission, The Ranch is committed to not only accommodating at-risk boys, but is trying to help them re-adjust and re-enter society with the skills necessary to function in every day life. The purpose of this paper is to evaluate The Ranch by examining the effectiveness of the program and its goals. Evaluation was done both Formatively and Summatively, through interviews and documentation. The researcher found that The Ranch has a variety of effective tools to evaluate and determine the progress of each boy\u27s behavior and attitude. This study found that The Ranch is effective in accomplishing its goals and striving to complete its mission

The Effects of Climate on Radial Growth of Disjunct Northern White Cedar (Thuja occidentalis L.) in Virginia

Understanding the geographic range and growth of species is essential for effective land management in a landscape affected by anthropogenic activity and climate change. Climate change is expected to alter the distribution and growth of many tree species in eastern North America, including northern white cedar (Thuja occidentalis L.). This research examined the effects of climate on radial growth of T. occidentalis in disjunct populations south of its continuous range margin in eastern North America. A T. occidentalis tree-ring chronology was developed and examined for growth-climate interactions. Mean sensitivity of the T. occidentalis chronology was within the range of values reported for the species in northern portions of its range. Significant positive correlations existed between the T. occidentalis chronology and moisture variables late in the growing season of the previous year and current year. The relationship between the T. occidentalis chronology and temperature was more variable with significant positive and negative correlations throughout the previous year and current year. The Ordinary Least Squares (OLS) regression model suggested moisture conditions late in the growing season of the previous year and current year had a significant positive influence on the growth of T. occidentalis. In contrast, maximum temperature in March of the current year negatively influenced the growth of T. occidentalis. While the mean sensitivity of T. occidentalis appears similar throughout its range, there is geographic variability in the climate-growth response of T. occidentalis. More research is necessary to expand the scope of our knowledge concerning T. occidentalis growth throughout its range

The Louisville and Nashville Railroad, 1850-1963

When the Louisville and Nashville Railroad was founded in 1850, it was the first major railroad in the west, and the only one headquartered in Kentucky. In the twentieth century, the L&N grew into one of the nation’s major rail systems, reaching from the Great Lakes to the Ohio River Valley and down to Florida and the Gulf Coast. Kincaid Herr worked for the Louisville and Nashville for more than forty years, and this book originated as a series of articles that he wrote for L&N Magazine between 1939 and 1942. After various printings through the 1940s and ’50s, this fifth edition, completely revised and updated, was released in 1964. The 1950s saw the reluctant abandonment of the old steam engine (the L&N was a major coal-carrying railroad) in favor of the diesel. During the late 1950s and early 60s, the railroad experienced significant expansion in the South, where the economy was being fueled by new industry. Coal, automobiles, mail, and passengers all counted on the L&N to get them around the region. Herr traces the development and expansion of the L&N system over a century and profiles important company figures, such as longtime L&N president Milton Smith. Confederate raider John Hunt Morgan and railroad bandit Morris Slater also find their place in this entertaining history. Four appendices on topics ranging from the materials used to build trains to passenger equipment to motive power round out the complete, but accessible, account. Even after all these years, this volume remains the concise, illustrated history of “The Old Reliable” for its many fans around the world. A classic and thorough history of an American institution. -- Bookman News, Library Booknotes Interesting and well illustrated. It should be a welcome gift for anyone who likes to read about railroads or the history of those states connected by the L & N Railroad. -- Bowling Green Daily News This is the best history of the L&N. -- Bulletin of the Railroad Station Historical Society Provides a well-written and richly detailed narrative of the evolution of America’s railroads of the world they did so much to shape. -- Carlos Schwantes A ‘jewel’ in railroad history. -- McCormick (SC) Messenger Illustrated with a veritable treasure trove of photographs and drawings spanning the life of the company. -- R.

Theorem on the Distribution of Short-Time Particle Displacements with Physical Applications

The distribution of the initial short-time displacements of particles is considered for a class of classical systems under rather general conditions on the dynamics and with Gaussian initial velocity distributions, while the positions could have an arbitrary distribution. This class of systems contains canonical equilibrium of a Hamiltonian system as a special case. We prove that for this class of systems the nth order cumulants of the initial short-time displacements behave as the 2n-th power of time for all n>2, rather than exhibiting an nth power scaling. This has direct applications to the initial short-time behavior of the Van Hove self-correlation function, to its non-equilibrium generalizations the Green's functions for mass transport, and to the non-Gaussian parameters used in supercooled liquids and glasses.Comment: A less ambiguous mathematical notation for cumulants was adopted and several passages were reformulated and clarified. 40 pages, 1 figure.

Interpersonal violence in peacetime Malawi.

Background: The contribution of interpersonal violence (IPV) to trauma burden varies greatly by region. The high rates of IPV in sub-Saharan Africa are thought to relate in part to the high rates of collective violence. Malawi, a country with no history of internal collective violence, provides an excellent setting to evaluate whether collective violence drives the high rates of IPV in this region. Methods: This is a retrospective review of a prospective trauma registry from 2009 through 2016 at Kamuzu Central Hospital in Lilongwe, Malawi. Adult (\u3e16 years) victims of IPV were compared with non-intentional trauma victims. Log binomial regression determined factors associated with increased risk of mortality for victims of IPV. Results: Of 72 488 trauma patients, 25 008 (34.5%) suffered IPV. Victims of IPV were more often male (80.2% vs. 74.8%; p Discussion: Even in a sub-Saharan country that never experienced internal collective violence, IPV injury rates are high. Public health efforts to measure and address alcohol use, and studies to determine the role of mob justice, poverty, and intimate partner violence in IPV, in Malawi are needed. Level of evidence: Level III

Multi-domain active sound control and noise shielding

This paper describes an active sound control methodology based on difference potentials. The main feature of this methodology is its ability to automatically preserve “wanted” sound within a domain while canceling “unwanted” noise from outside the domain. This method of preservation of the wanted sounds by active shielding control is demonstrated with various broadband and realistic sound sources such as human voice and music in multiple domains in a one-dimensional enclosure. Unlike many other conventional active control methods, the proposed approach does not require the explicit characterization of the wanted sound to be preserved. The controls are designed based on the measurements of the total field on the boundaries of the shielded domain only, which is allowed to be multiply connected. The method is tested in a variety of experimental cases. The typical attenuation of the unwanted noise is found to be about 20 dB over a large area of the shielded domain and the original wanted sound field is preserved with errors of around 1 dB and below through a broad frequency range up to 1 kHz. © 2011 Acoustical Society of Americ

Phase behavior of a system of particles with core collapse

The pressure-temperature phase diagram of a one-component system, with particles interacting through a spherically symmetric pair potential in two dimensions is studied. The interaction consists of a hard core plus an additional repulsion at low energies. It is shown that at zero temperature, instead of the expected isostructural transition due to core collapse occurring when increasing pressure, the system passes through a series of ground states that are not triangular lattices. In particular, and depending on parameters, structures with squares, chains, hexagons and even quasicrystalline ground states are found. At finite temperatures the solid-fluid coexistence line presents a zone with negative slope (which implies melting with decreasing in volume) and the fluid phase has a temperature of maximum density, similar to that in water.Comment: 11 pages, 15 figures included.
