Student Mathematics Performance in Year One Implementation of Teach to One: Math

This report examines mathematics test data from the first year of implementation (2012-13) of the Teach to One: Math (TtO) approach in seven urban middle schools in Chicago, New York City, and Washington D.C. Researchers addressed the question: How did Tto students' growth on the Measures of Academic Progress (MAP) mathematics assessment compare with national norms?To answer this question, the researchers analyzed student performance on the MAP test, an established instrument developed by the Northwest Evaluation Association (NWEA). The researchers then compared these results to the national norms published by NWEA (2011). Please note that these analyses cannot attribute Tto student results to the TtO model: the data available did not permit the use of an experimental design, which would be necessary to establish a link between the implementation of the program and the student test results. While the TtO results are promising, its performance beyond one year should be analyzed using an experimental design, in order to remove unmeasured differences between TtO students and schools with an appropriate comparison sample

Still Separate, Still Unequal, But Not Always So Suburban : The Changing Natured of Suburban School Districts in the New York Metropolitan Area

Woven throughout the history of the United States is a narrative of human movement. The story of this country, we argue, is a tale of the constant flow of people across geographic spaces—both voluntary and forced immigrations, migrations, and the settlements of villages, city neighborhoods, and suburban communities. Beginning with Native Americans\u27 ancestors who traversed the Bering Straight, movement has been a central, identifying theme of this nation. The flow of several waves of European immigrants onto colonial shores and across the plains and the haulage of millions of Africans via the slave trade redefined the United States demographically and geopolitically, as did the mass migration of freed African Americans from the South to the North and from the farms to the cities in the 20th century. The post- World War II construction of suburbia enabled the European immigrants and their decedents to migrate from the cities to the suburbs en masse, changing not only the character of suburbia but also the cities and ethnic enclaves they left behind. As if choreographed by the federal government, local zoning laws and real estate markets, this flow of whites to the suburbs was synchronized with the arrival of African American migrants into specific and highly contained city neighborhoods. But even the resulting racially segregated pattern of vanilla suburbs and chocolate cities that seemed fairly stable by the late 1970s across most metro areas was subject to change. Beginning in the late 1960s, new waves of immigrants, primarily from Latin America and Asia, entered the urban neighborhoods abandoned by their European immigrant predecessors. By the 1980s, growing numbers of African Americans had begun migrating to the suburbs. And, in the last decade, more Latino and Asian immigrants have chosen suburban communities as their port of entry to the United States. At the same time, whites— particularly affluent and well-educated professionals—are migrating back into cosmopolitan and gentrified city neighborhoods, opting out of increasingly diverse suburbs

Divided We Fall: The Story of Separate and Unequal Suburban Schools 60 Years after Brown v. Board of Education

This report is a clarion call for those paying attention to the changing racial and ethnic demographics of this country and its suburbs in particular. It is the in-depth story of one suburban county and its public schools as the demographics of who lives in the suburbs versus the cities in the 21st century is shifting quickly, as the affluent and the poor, the black and the white are trading places across urban-suburban boundary lines. The same story could be told about hundreds of suburban counties across the country that are facing similar pressures and approaching similar breaking points. In the statistical data we analyzed and in the voices of the 800 people we interviewed and surveyed in Nassau County, Long Island - the home of Levittown, the first post-WWII archetypal suburb -- there is mounting anxiety about the future of American suburbs and their public schools. We found much frustration about how the economy, housing market, lack of infrastructure and public policies negatively affect these communities. In this report, we convert this angst into a reality check for anyone who may think that racially and ethnically diverse suburbs are easily accomplished or that they do not face serious obstacles. These obstacles include racially and ethnically segregated housing patterns amid fragmented and divided municipalities and school districts and the brain drain of more affluent and educated residents who grew up in the suburbs but now prefer city life. Meanwhile, these suburbs are tubs on their own bottoms, heavily reliant on local sources of funding, namely property taxes, to pay for public schools and municipal services. This means that public school resources and reputations are spread unevenly across separate and unequal suburban school districts

To meat or not to meat? New perspectives on Neanderthal ecology.

Neanderthals have been commonly depicted as top predators who met their nutritional needs by focusing entirely on meat. This information mostly derives from faunal assemblage analyses and stable isotope studies: methods that tend to underestimate plant consumption and overestimate the intake of animal proteins. Several studies in fact demonstrate that there is a physiological limit to the amount of animal proteins that can be consumed: exceeding these values causes protein toxicity that can be particularly dangerous to pregnant women and newborns. Consequently, to avoid food poisoning from meat-based diets, Neanderthals must have incorporated alternative food sources in their daily diets, including plant materials as well

Unexpected species diversity in electric eels with a description of the strongest living bioelectricity generator

Is there only one electric eel species? For two and a half centuries since its description by Linnaeus, Electrophorus electricus has captivated humankind by its capacity to generate strong electric discharges. Despite the importance of Electrophorus in multiple fields of science, the possibility of additional species-level diversity in the genus, which could also reveal a hidden variety of substances and bioelectrogenic functions, has hitherto not been explored. Here, based on overwhelming patterns of genetic, morphological, and ecological data, we reject the hypothesis of a single species broadly distributed throughout Greater Amazonia. Our analyses readily identify three major lineages that diverged during the Miocene and Pliocene—two of which warrant recognition as new species. For one of the new species, we recorded a discharge of 860 V, well above 650 V previously cited for Electrophorus, making it the strongest living bioelectricity generator. © 2019, The Author(s)

A comparative analysis of multicultural perspectives on leadership competencies and organizational capabilities required for competitiveness in the 1990's

This thesis considers three main arguments. -First, that managersfrom different cultural orientations tend to look at competitive, organizational and leadership challenges differently due to their cultural orientation or "mapping". Second, that even though it appears that, managers,, from various cultures may have different cultural maps, it is-possible to find a "muld cultural common ground" concerning the organizational capabilities and leadership competencies perceived as critical for competitiveness in the 90's. And third, that a perceived challenge facing senior managers in the 90's is managing the tensions and processps of transformation and change resulting from attempts to develop a shared meaning of the company's vision, balanced by an operating culture that encourages substantial differences in perspectives. The introduction provides a rationale for the importance of the topic and explores this researcher's interest in the subject. It also provides the foundation for definitions and operating terms for a number of the words or phrases that are used throughout the text. , The' review, of the literature examines both the general breadth of this researcher's reading program that served as preparation for the study, as well as a look at the works that served as important foundations for the focal points of this research. It also explains how the literature influenced the research methods. The thesis arguments provide the main questions that are examined in the research and includes the backgrounds and premises for selecting these arguments. The value and benefits of the research are also examined here. The research methodologies chapter details in depth the processes used to conduct the research, provides the linkages between the methods and the literature and explores the use of analytical tools and frameworks in the study of managerial perceptions. The results chapter presents the main findings of the research and explains how these findings support the thesis arguments. A subsequent discussion of these results, their linkage to the literature and an explanation of their meaning is discussed in the next chapter. Finally, the main lessons of the research, the value of the methodologies, the implications of the research for practicing managers and researchers and suggestions for additional research are explored in the conclusions. While the statistical procedures'are explained in great depth, many of the actual data tables and detailed findings, as well as the questionnaire used may be found in the appendices
