Energy and system size dependence of phi meson production in Cu plus Cu and Au plus Au collisions

We study the beam-energy and system-size dependence of phi meson production (using the hadronic decay mode phi -> K(+) K(-)) by comparing the new results from Cu + Cu collisions and previously reported Au + Au collisions at root s(NN) = 62.4 and 200 GeV measured in the STAR experiment at RHIC. Data presented in this Letter are from mid-rapidity (vertical bar y vertical bar < 0.5) for 0.4 < p(T) < 5 GeV/c. At a given beam energy, the transverse momentum distributions for phi mesons are observed to be similar in yield and shape for Cu + Cu and Au + Au colliding systems with similar average numbers of participating nucleons. The phi meson yields in nucleus-nucleus collisions, normalized by the average number of participating nucleons, are found to be enhanced relative to those from p + p collisions. The enhancement for phi mesons lies between strange hadrons having net strangeness = 1 (K(-) and <(A)over bar>) and net strangeness = 2 (Xi). The enhancement for phi mesons is observed to be higher at root s(NN) = 200 GeV compared to 62.4 GeV. These observations for the produced phi(s (s) over bar) mesons clearly suggest that, at these collision energies, the source of enhancement of strange hadrons is related to the formation of a dense partonic medium in high energy nucleus-nucleus collisions and cannot be alone due to canonical suppression of their production in smaller systems.

Now What!?! Exploring the Next Steps for Large-scale Library Assessment Projects

EdTech Innovator Chase: Rewarding Faculty Innovation through badges

Each semester we celebrate our college EdTech Innovators– everyone who’s using technology to explore new pedagogical approaches. We applaud early adopters for developing best practices, because maybe they’re doing something nobody else has. Those who innovate in the most EdTech areas and (most importantly!) help their colleagues level up, compete for the epic win. The EdTech Innovator Chase, a gamified activity (digital badges) was created to showcase faculty innovations in teaching practices.

This is your brain on the iPad

The proliferative usage of multimedia tools in the classroom reflects an increasingly technocratic education system. Technology provides educators with new opportunities to reach students in innovative ways. We describe the use of iPads and several proprietary applications in a General Psychology course as one opportunity to improve student learning outcomes. Quantitative and qualitative evidence will be provided of the pre- and post-tests, which both show positive significant outcomes.

Levine Family Reunion Members, interviewed by Wendy Miller in September 2009: Transcript

The Levine family held an extensive reunion during the Summer of 2009 during which 29 DVDs of raw material were recorded for use in the creation of a Levine family mini-documentary. Many of these DVDs contain oral history interviews conducted by Wendy Miller, one of the organizers of the reunion. Although these interviews were not designed for historical research, they contain valuable historical information. Some of the family members interviewed include: Ben Arnon (4/5), Marjorie, Stephen, and Michael Kaplan (8), Glenyce Miller Kaplan (starts in 15, continues in 9; separate interview in 13), Burt, Phyllis, and Louis Shiro (9) [Burt Shiro also in 26/27], Myrt and Gordon Wolman (9), Ted and Billy Alfond (10), Barbara and Joan Alfond (10), Susan and Peter Alfond (10), Alice Emory [caregiver for Bibby] (11), Eric Bloom and Stu Cushner (11), Saralee Kaplan Bloom (11), Sarah Miller Arnon (12), Kayla and Jenna Cushner (12), Josh Soros and Eliana Miller-Kaplan (12), Sarah, Wendy, and Julie Miller (starts in 12, continues in 14), Bill Shutzer (13), Maschia and Glicka Kaplan, Sharon Kushner, Dan Hood (13), Gene, Alex, Kate Cohen (14), Ben, Jeremy, Joselyn Arnon (14), Wendy and Julie Miller at the store (15), and Eric Bloom (15).

A Catalyst for Culture: Early Child Development and Education in Japan

A popular Western perception of Japan is that it is an eminently homogeneous and conformist society. However, both conformity and homogeneity, recognized even by the Japanese themselves, coexist with the concept of individuality, which is valued in a manner unique to its culture. In order to come to a deeper understanding of that dynamic, it is important to comprehend the specifics of child rearing and education within Japanese society. Based in part on the author's observational fieldwork conducted while in Japan in 1994, the thesis explicates the manner in which various core relationships exhibit the socialization of an individual that occurs within the home during a child's first few years. Furthermore, the text incorporates research in both primary and secondary historical materials. The author displays the manner in which educational issues such as the development of the Japanese education system and the dynamics of the elementary years serve to demonstrate the importance of functioning within a group. This is further clarified through an examination of elementary school texts, which also reveal underlying moral messages of profound importance in Japanese society. The seemingly contradictory issues of becoming an individual yet performing as a member of a group are pulled together by the idea that culture provides the guidance by which an individual becomes an active member of society. In Japan, individuality and group conformity are not mutually exclusive. Within the context of Japanese society, individuality is inextricably linked to group orientation.

A implementação do Programa Nacional de Alimentação Escolar (PNAE) em municípios de pequeno porte: implicações práticas e teóricas

O Programa Nacional de Alimentação Escolar (PNAE), o mais antigo programa de alimentação e nutrição do país e o maior de alimentação escolar gratuita do mundo, tem chamado a atenção nos últimos anos. E não é devido, apenas, à sua longevidade e escala, mas à oportunidade de aquisição de produtos da agricultura familiar para a merenda escolar, com a entrada em vigor da Lei Federal nº 11.947/09. A abertura deste mercado institucional possibilita a utilização de, no mínimo, R$ 1,05 bilhão na compra de produtos de pequenos produtores rurais (FNDE, 2014), que têm padecido de dificuldades de comercialização. Circulam no governo e na academia afirmações sobre as contribuições dessa iniciativa para o desenvolvimento rural, desenvolvimento local e dos agricultores e suas famílias. É necessária, todavia, uma melhor compreensão de como o Programa tem funcionado na prática. A fim de contribuir para essa discussão, a pergunta de pesquisa que norteou esta dissertação foi: Quais são os desafios para a implementação do PNAE, especificamente da compra de produtos da agricultura familiar, em municípios de pequeno porte? Que foi abordada através de uma pesquisa qualitativa exploratória que reuniu: levantamento bibliográfico sobre implementação (Hill & Ham, 2003; Faria, 2013), abordagens (Spink, 2013; Spink & Silva, no prelo) e análise de políticas públicas (Subirats et al 2008); análise dos documentos oficiais do Programa; e estudo de caso em três municípios mineiros – São Gonçalo do Rio Abaixo, Orizânia e Capitão Enéas. Os achados da pesquisa apontam que a imposição da compra de produtos da agricultura familiar tem apresentado um caráter maior de incentivo aos municípios que não a realizavam, do que punitivo. Apontam ainda que atores estatais e públicos têm sido fundamentais na tradução das normas e na negociação dos diferentes interesses, muitas vezes conflitantes, para que essa aquisição seja de fato posta em prática. Diferentes foram os desafios encontrados. Todavia, devido à heterogeneidade dos municípios, ao invés de determiná-los, sugerimos dez pontos de atenção para a análise e gestão do Programa. Do ponto de vista de inclusão comercial dos agricultores, o PNAE possui sérios limites e parece estar contribuindo mais para o fortalecimento de pequenos produtores desenvolvidos do que para a inclusão daqueles mais frágeis produtivamente. Contudo, são necessários avanços na compreensão do funcionamento desse Programa em municípios de médio e grande porte. De igual relevância, o olhar mais atento sobre quais pequenos produtores têm acessado o mercado institucional e outras políticas públicas aparecem como caminhos profícuos para outras pesquisas no tema.
