Data from: Testing the link between population genetic differentiation and clade diversification in Costa Rican orchids
No full textSpecies population genetics could be an important factor explaining variation in clade species richness. Here we use newly generated AFLP data to test whether five pairs of sister clades of Costa Rican orchids that differ greatly in species richness also differ in average neutral genetic differentiation within species, expecting that if the strength of processes promoting differentiation within species is phylogenetically heritable, then clades with greater genetic differentiation should diversify more. Contrary to expectation, neutral genetic differentiation does not correlate directly with total diversification in the clades studied. Neutral genetic differentiation varies greatly among species and shows no heritability within clades. Half of the variation in neutral genetic differentiation among populations can be explained by ecological variables, and species-level traits explain the most variation. Unexpectedly, we find no isolation by distance in any species, but genetic differentiation is greater between populations occupying different niches. This pattern corresponds with those observed for microscopic eukaryotes and could reflect effective widespread dispersal of tiny and numerous orchid seeds. Although not providing a definitive answer to whether population genetics processes affect clade diversification, this work highlights the potential for addressing new macroevolutionary questions using a comparative population genetic approach
Liberal Nationalism of Yael Tamir:Theory and Polemics
No full textThis thesis deals with a theory of liberal nationalism, specifically its rendition presented by an Israeli author Yael Tamir. The set goal is to provide a detailed description of this specific interpretation using a theoretical framework provided by Michael Freeden. His definition of nationalism as a complementing rather than full-fledged ideology, as is the case with liberalism for example, provides an ideal framework for us to use when attempting to analyze the work of Tamir due to her trying to improve liberal theory by adding positive elements present in nationalism to it. After the full description of this form of liberal nationalism is made, the thesis then proceeds to introduce critics of said literary work, namely from critics such as Bernard Yack, Jamie Mayerfeld, or Liah Greenfeld, but also from the author herself, who had published a book dealing with similar topic 26 years after publishing the one this thesis focuses on. The goal is then to ascertain how the author's ideas changed during this time period. The thesis aims to give a descriptive account of a theory that seems to be an oxymoron at first glance, as liberalism and nationalism tend to be considered as opposites of a spectrum. Whether it is a theoretical approach that holds merit and could be helpful in our attempts to...Tato diplomová práce se zabývá liberálním nacionalismem, konkrétně jeho formulací z pera izraelské autorky Yael Tamir. Cílem je poskytnout detailní charakteristiku konkrétní podoby tohoto teoretického přístupu použitím teoretického rámce nabídnutého Michaelem Freedenem. Jeho definice nacionalismu jakožto obohacující ideologie namísto ideologie plnohodnotné, za kterou se dá považovat například liberalismus, je silně kompatibilní s teorií Yael Tamir, která se pokouší o zdokonalení liberální ideologie skrze absorbování komplementárních prvků nacionalismu. Po představení této konkrétní podoby liberálního nacionalismu je čtenáři přiblížena kritika tohoto díla a to jak ze strany kritiků jako Bernard Yack, Jamie Mayerfeld, nebo Liah Greenfeld, tak ze strany samotné autorky, která svou druhou knihu na téma nacionalismu vydala 26 let po vydání knihy první. Cílemje tak zjistit, zda, případně dojaké míry se změnil názor autorky napříč lety. Práce si klade za cíl představit teoretický přístup, který se zdá být na první pohled oxymoronem, neboť liberalismus a nacionalismus stojí v očích mnoha v opozici. Zda se jedná o proud představující cestu kupředu ve snaze zvrátit současnou krizi liberalismu, nebo o slepou uličku záleží na úsudku čtenáře.

“I get by with a little help from my friends": a survey of teachers' perceptions of adminstative support and their attitudes toward inclusion in New Jersey
No full textPrior to federal law PL-94-142, children with disabilities typically were excluded from regular, mainstream classes. This law emphasized the least restrictive environment since research had shown that all children benefited from inclusive learning environments. In the late 1990s, New Jersey was cited as having too high a proportion of children with disabilities in segregated placements. New Jersey received a State Improvement Grant (SIG) to increase the number of students with disabilities in regular education classes. This dissertation was designed to evaluate one aspect of local school districts’ program initiatives to achieve this end: teachers’ attitudes and perceptions regarding inclusion. Teachers are responsible for the daily implementation of inclusion practices. Their attitudes, perceptions, and beliefs are crucial for the success of inclusion. Although findings from previous research have indicated that teachers favor inclusion, their willingness to implement inclusive practices depends on the availability of supports and resources, as well as the attitudes of school personnel. A total of 856 general education, special education, and special area teachers from seven districts in New Jersey were surveyed regarding: (a) their attitudes and beliefs about inclusion; (b) their perceived administrative support; (c) their perceived ease in meeting the needs of students with disabilities in their classroom; and (d) the factors that have helped or hindered their ability to include students with disabilities in their classroom. Quantitative (Pearson product-moment correlation, multiple regression, independent samples t test) and qualitative (content analysis) methods were used to analyze the survey data. Special education teachers had more positive attitudes toward inclusion than did general education teachers. Relationships between teachers' attitudes and perceptions, and administrative support were found for general education teachers but not for special education teachers. Years of experience working with students with disabilities did not influence these relationships. Teachers identified training, positive attitudes, and support from colleagues, administrators, and other school personnel as factors facilitating inclusive practices. Barriers to implementation included large class size, insufficient planning time, lack of support from colleagues and school administrators, student behavior and ability, and teachers' negative attitudes. Implications for practice are discussed for administrators and school psychologists.Psy.DIncludes bibliographical references (p. 112-123)by Yael Rachel Shemes
Native Land Talk: Indigenous and Arrivant Rights Theories (Yael Ben-zvi)
No full textYael Ben-zvi, Native Land Talk: Indigenous and Arrivant Rights Theories. Dartmouth UP, 2018. 276 pp. ISBN: 9781512601466. www.upne.cpm In Native Land Talk: Indigenous and Arrivant Rights Theories, Yael Ben-zvi employs EuroAmerican human rights theories to examine and compare the distinctive resistances of African and indigenous Americans to colonization. Delving into a rich array of resources—petitions, letters, newspaper articles, and speeches, among others--to examine EuroAmerican rights claims, Ben-zvi inventively applies these theoretical histories to the petitions and appeals for freedom and land made by indigenous and African American peoples in the eighteenth and nineteenth centuries (roughly 1760-1840). The author closely analyzes aspects of settler rights claims and indigenous and African American histories of resistance (or, as she terms them, “unsettlement projects”) that have received little scholarly attention, aligning the resistance of the latter communities with settler dehumanization and violence
