Effectiveness of the Teaching Enrichment Activities to Minorities (TEAM) program at increasing underrepresented students in gifted programs

This study examined the effectiveness of the TEAM (Teaching Enrichment Activities to Minorities) program in preparing and identifying underrepresented students for entrance into the gifted program. Miami-Dade County Public Schools (M-DCPS) developed the TEAM program as an intervention program aimed at developing student's thinking skills and critical thinking skills in all subject areas and prepare students for possible placement into the gifted program. ^ A systematic sampling strategy was utilized to select three TEAM schools from each of the six regions in M-DCPS for the sample, for a total of 18 schools. A pool of the students that participated in the TEAM program in 2003-2004 in the 18 schools selected were identified as the TEAM Sample students. A matching sample was created from 18 public schools in Miami-Dade County that did not implement the TEAM program in 2003-2004. The Matching Sample created a match for 806 students in the TEAM sample, for a total of 1612 subjects for the study. ^ This study used a logistical regression design to analyze the relationships of multiple independent variables, including: ethnicity, limited English proficiency, gender, free/reduced lunch status, grade level, reading achievement, mathematics achievement, and participation TEAM on the dependent variables of referral for the gifted program and eligibility into the gifted program. The first analysis found the variables of grade level, participation in TEAM, reading achievement, and mathematics achievement were all significant variables in determining if a student was referred for the gifted program. The second analysis found the variables of grade level, gender, free/reduced lunch status, reading achievement, and mathematics achievement were all significant variables in determining if a student was eligible for the gifted program. ^ Recommendations based on the results of this study include the expansion of the TEAM program in M-DCPS to include additional grade levels and schools. Additionally, adopting a broadened definition of giftedness and reviewing the screening and placement policies for potentially gifted students is recommended. Adopting multicultural and broader definitions of giftedness and constructing better tools and programs, such as TEAM, for assessing and identifying potential gifted students, represent small steps towards creating equitable education for all students. ^

The Effect of Nutrient-Rich Effluents from Shrimp Farming on Mangrove Soil Carbon Storage and Geochemistry Under Semi-Arid Climate Conditions in Northern Brazil

A semi-arid mangrove estuary system in the northeast Brazilian coast (Ceará state) was selected for this study to (i) evaluate the impact of shrimp farm nutrient-rich wastewater effluents on the soil geochemistry and organic carbon (OC) storage and (ii) estimate the total amount of OC stored in mangrove soils (0–40 cm). Wastewater-affected mangrove forests were referred to as WAM and undisturbed areas as Non-WAM. Redox conditions and OC content were statistically correlated (P < 0.05) with seasonality and type of land use (WAM vs. Non-WAM). Eh values were from anoxic to oxic conditions in the wet season (from − 5 to 68 mV in WAM and from < 40 to > 400 mV in Non-WAM soils) and significantly higher (from 66 to 411 mV) in the dry season (P < 0.01). OC contents (0–40 cm soil depth) were significantly higher (P < 0.01) in the wet season than the dry season, and higher in Non-WAM soils than in WAM soils (values of 8.1 and 6.7 kg m− 2 in the wet and dry seasons, respectively, for Non-WAM, and values of 3.8 and 2.9 kg m− 2 in the wet and dry seasons, respectively, for WAM soils; P < 0.01). Iron partitioning was significantly dependent (P < 0.05) on type of land use, with a smaller degree of pyritization and lower Fe-pyrite presence in WAM soils compared to Non-WAM soils. Basal respiration of soil sediments was significantly influenced (P < 0.01) by type of land use with highest CO2 flux rates measured in the WAM soils (mean values of 0.20 mg CO2 h− 1–g− 1 C vs. 0.04 mg CO2 h− 1–g− 1 C). The OC storage reduction in WAM soils was potentially caused (i) by an increase in microbial activity induced by loading of nutrient-rich effluents and (ii) by an increase of strong electron acceptors [e.g., NO3−] that promote a decrease in pyrite concentration and hence a reduction in soil OC burial. The current estimated OC stored in mangrove soils (0–40 cm) in the state of Ceará is approximately 1 million t.

Immigration and nationalism in Greece

A source of emigration until the early 1970s, Greece has become home to a rising tide of immigrants since 1991, and its foreign-born population rose from below one to over 11 percent. Equally important is the fact that the Greek state has historically premised national belonging on ethnicity, and striven to exclude people who did not exhibit Greek ethnic traits. My study examines how immigration has challenged this nationalist model of ethnically homogeneous belonging. Further, it uses the Greek case to problematize the hegemonic assumption that the nationalist model of social organization is a human universal. Data consist of reactions to a 2010 landmark law that constituted the first jus soli bill in the nation's history, and include a plurality of voices found in parliamentary proceedings, newspapers, a government-sponsored online forum and Facebook discussions. Voices examined correspond to three main conceptual camps: people who premise belonging on ethnicity and hegemonic definitions of what it means to be Greek, people who mitigate nationalist norms enough to include immigrants, but reproduce a nationalist worldview, and people who seek to divorce political belonging from ethnicity altogether.

A Body Outside the Kremlin

A BODY OUTSIDE THE KREMLIN is a historical mystery novel set in the Northern Camps of Special Significance, a Soviet Russian penal institution based in the Solovetsky Archipelago during the 1920s. The protagonist, working first with the camp authorities, then in spite of their disapproval, solves the murder of a fellow prisoner. In the process he improves his position within the camp, while also becoming hardened to the brutal necessities of camp life. Prior to the establishment of the penal camp, the Solovetsky Archipelago was the site of an important Russian Orthodox monastery, and the mystery proves to involve valuables, particularly icons, seized from the monks by the Soviet secret police. Thus the novel treats themes not only of statist repression, but also religious epiphany and the problems of true perception in a world of symbols.

Previous Holocaust Experiences Continue to Affect Food Attitudes in Survivors

A qualitative study was conducted to determine if Holocaust survivors’ food attitudes are influenced by their earlier experiences. The 25 survivor interviewees (14 males, 11 females) ranged in age from 71 to 85 years and resided in Miami-Dade and Broward, Florida counties. Most (56%) were interned in concentration camps during the Holocaust. Interviews were tape-recorded and later transcribed. Results showed earlier experiences influenced food attitudes. The most common themes were: 1) Difficulty throwing food away - even when spoiled; 2) Storing excess food; 3) Craving a certain food; 4) Difficulty standing in line for food; and 5) Anxiety when food is not readily available. Sub-themes included healthy eating and empathy for those currently suffering from hunger. Fourteen (56%) fast for religious holidays, but 7 (28%) said they already had “fasted enough.” Dietitians and others are encouraged to evaluate food service programs to minimize uncomfortable food-related situations for Holocaust survivors.

Overnight Summer Music Camp and the Impact on its Youth: A Case Study

This qualitative case study explores an overnight music camp, Camp Encore Coda. The purpose is to gain an understanding of the environment, uncovering the unique ways it impacts the social and musical developments of its participating youth while contrasting it to that of the traditional classroom. Framed by the concept of multidimensional growth, data were collected using surveys, interviews, focus group, and observations. The study uncovered exorbitant levels of social and musical growth among the youth; all directly linked to isolation from technology, communal living, and musical immersion in a community of practice. There lacks a significant amount of music education research attempting to explore and provide an initial evaluation of the learning opportunities unique to overnight music camps. This is particularly significant for music educators who strive to continue the advancement of the field through positive impact on students inside and outside of the school classroom.

Effect of Pavement-Vehicle Interaction on Highway Fuel Consumption and Emission

Vehicle fuel consumption and emission are two important effectiveness measurements of sustainable transportation development. Pavement plays an essential role in goals of fuel economy improvement and greenhouse gas (GHG) emission reduction. The main objective of this dissertation study is to experimentally investigate the effect of pavement-vehicle interaction (PVI) on vehicle fuel consumption under highway driving conditions. The goal is to provide a better understanding on the role of pavement in the green transportation initiates. Four study phases are carried out. The first phase involves a preliminary field investigation to detect the fuel consumption differences between paired flexible-rigid pavement sections with repeat measurements. The second phase continues the field investigation by a more detailed and comprehensive experimental design and independently investigates the effect of pavement type on vehicle fuel consumption. The third study phase calibrates the HDM-IV fuel consumption model with data collected in the second field phase. The purpose is to understand how pavement deflection affects vehicle fuel consumption from a mechanistic approach. The last phase applies the calibrated HDM-IV model to Florida’s interstate network and estimates the total annual fuel consumption and CO2 emissions on different scenarios. The potential annual fuel savings and emission reductions are derived based on the estimation results. Statistical results from the two field studies both show fuel savings on rigid pavement compared to flexible pavement with the test conditions specified. The savings derived from the first phase are 2.50% for the passenger car at 112km/h, and 4.04% for 18-wheel tractor-trailer at 93km/h. The savings resulted from the second phase are 2.25% and 2.22% for passenger car at 93km/h and 112km/h, and 3.57% and 3.15% for the 6-wheel medium-duty truck at 89km/h and 105km/h. All savings are statistically significant at 95% Confidence Level (C.L.). From the calibrated HDM-IV model, one unit of pavement deflection (1mm) on flexible pavement can cause an excess fuel consumption by 0.234-0.311 L/100km for the passenger car and by 1.123-1.277 L/100km for the truck. The effect is more evident at lower highway speed than at higher highway speed. From the network level estimation, approximately 40 million gallons of fuel (combined gasoline and diesel) and 0.39 million tons of CO2 emission can be saved/reduced annually if all Florida’s interstate flexible pavement are converted to rigid pavement with the same roughness levels. Moreover, each 1-mile of flexible-rigid conversion can result in a reduction of 29 thousand gallons of fuel and 258 tons of CO2 emission yearly.
