High Stakes Testing In Louisiana: An Analysis Of The Disparate Impact On Black And White Eighth Grade Students And The Perspectives Of Parents, Monica L. Mancuso

LSU Doctoral Dissertations

Standards based reform (SBR) measured by LEAP for the 21st Century (LEAP 21), the high stakes testing program in Louisiana, was explored across rural, suburban, and urban school community types. Differences in scores of Black and White eighth graders on LEAP 21 were analyzed using a multivariate analysis of variance (MANOVA), revealing race and the interaction of race and community type to be statistically significant at p< .05. Black students did not score as well as White students when scores were analyzed by pass/fail and achievement level differences. The percentage of Black students passing the test increased at rates greater than White students when scores from magnet schools were included. Parents of eighth graders disagreed with the use of a single criterion for promotion. Parents said the instruction students received, pace of instruction, and stress of testing negatively affected student performance with the result that their children considered a Graduate Equivalency Diploma (GED) or quitting school. Parents agreed that affluence and the level of family support affected students’ test performance. Some parents also believed it was unfair that non-public school students were not required to take or pass such tests and some parents considered enrolling their child in a non-public school to avoid the consequences of the state testing program.

The Effects Of Nutrient Enrichment On The Decomposition Of Belowground Organic Matter In A Sagittaria Lancifolia - Dominated Oligohaline Marsh, Kristen Raye Laursen

LSU Master's Theses

Wetlands improve water quality through sedimentation and the uptake of excess nutrients. As human population increases in the coastal zone, wetlands receive greater nutrient inputs. These additional nutrients may accelerate microbial activity, leading to faster decomposition rates. This decomposition could exceed belowground organic matter production, resulting in a net reduction in soil organic matter accumulation and vertical marsh accretion. The effects of nutrient enrichment on belowground organic matter decomposition in subtropical marshes have received little attention. As such, this research examined the effects of four levels of nitrogen combined with two levels of phosphorus enrichment on belowground decomposition through the …

Species Diversity And Biogeography Of Ants (Hymenoptera: Formicidae) In Louisiana With Notes On Their Ecology, Shawn T. Dash

LSU Master's Theses

Over three decades have passed since the completion of Moser and Blum's (1960) treatment of the ants of Louisiana. This research represents a significant contribution to and update of their work. I report the first-ever comprehensive assessment of the Louisiana Formicid fauna. More than 100 species from 38 genera and eight subfamilies are covered. This faunistic survey gives valuable data of biodiversity and macro/microhabitat selection of ant species. Included are keys to all subfamilies, genera, and species with illustrations photographs, and a regional map for each species.

The Atchafalaya Basin Proposal For Nomination To The World Heritage Site List, Mitchell W. Coffman

LSU Master's Theses

The Atchafalaya Basin in the Southern United States is a cultural, environmental, historical and natural land region of such universal importance, designation as a World Heritage Site is appropriate. This thesis provides a justification for this designation through compliance with cultural and natural criteria detailed in the Convention Concerning the Protection of the World Cultural and Natural Heritage of 1972. The treaty, also known as the World Heritage Convention (WHC) promotes natural and cultural landscape preservation on an international level. This thesis lists the cultural and natural arguments for nominating the Atchafalaya Basin to the World Heritage Site list.

Extreme Precipitation Events In East Baton Rouge Parish: An Areal Rainfall Frequency/Magnitude Analysis, Michelle Marie Russo

LSU Master's Theses

Severe rainfall events are one of the most frequent weather hazards in the United States. These events are particularly problematic for the southeastern United States because of its subtropical climate. For these reasons, and because of the recent urban growth in the parish, East Baton Rouge Parish officials are concerned whether the current stormwater drainage system can keep pace with development. As a result, this project evaluated the rainfall frequency/magnitude for parish-wide extreme events and their synoptic forcing mechanisms. To this end, this research mapped parish-wide storms and compared three interpolation techniques. It also compared two methods of areal summation …

Capturing The Ordinary: Russell Lee In Southeastern Louisiana, Brent Mitchell

LSU Master's Theses

The photographers who worked for the Farm Security Administration Historical Section from 1935-1942 produced a large body of photographic work that now resides in the Library of Congress. These photographs serve as valuable visual resources for depicting an economically deprived section of America's population during the Great Depression and the Dust Bowl. Some of these photographers, like Walker Evans and Dorothea Lange, are widely recognized for their work, while others remain obscure. Russell Lee falls into the latter category, although he contributed the largest number of captioned photographs to the FSA photographic files. This paper explores Lee's photographic techniques in …
