A pedagógus-diák közötti kötődés jellemzése egy hazai vizsgálat tükrében
Authors: Szabó Lilla , Rausch Attila , Zsolnai Anikó
Published: May 2019

Míg korábban a neveléstudományi kutatások jellemzően a személyiségfejlesztés kognitív szférájára fókuszáltak, nemzetközi viszonylatban közel 60 éve, Magyarországon pedig az utóbbi két évtizedben a tanulást befolyásoló affektív tényezők vizsgálata is előtérbe került (Józsa és Fejes, 2012). E tényezők közül az iskolai kötődések vizsgálatára hazánkban eddig kevés kutató vállalkozott (például Szabó és Virányi, 2011), a pedagógusdiák közötti kötődéssel pedig csak érintőlegesen foglalkoztak (Zsolnai, 2018). A pedagógus és diák közötti kötődés az eredményes nevelés talán legfontosabb feltétele (Sava, 2002). Rövid és hosszú távon egyaránt szignifikáns hatással van a személyiségfejlődésre és az iskolai sikerességre (például Sabol és Pianta, 2012), mely hatás nem csak kisgyermekkorban, hanem serdülőkorban is érvényesül (Verschueren, 2015). Tanulmányunk első részében a kötődés fogalmának és alakulásának rövid tárgyalását követően bemutatjuk a pedagógus-diák közötti kötődést vizsgáló nemzetközi kutatások alapjaként szolgáló értelmezéseket, áttekintést adunk a nemzetközi kutatásokban használatos vizsgálati módszerekről és eszközökről. Ezt követően egy széles körben alkalmazott, pedagógusi percepción alapuló mérőeszköz (Pianta, 2001) hazai kipróbálásának első eredményeiről számolunk be.
Lemorzsolódási rizikófaktorok a felvételi adatbázis alapján
Authors: Józsa Gabriella
Published: May 2019

A felsőoktatás átalakulásával a hallgatói társadalom is átalakult. Az eddig szűk rekrutációs bázisra épülő egyetemek kapui széles társadalmi rétegek számára nyíltak meg. A hallgatói összetétel heterogenitásával megjelent a lemorzsolódás jelensége, ami nem csak a felsőoktatást és Magyarországot érinti, hanem a közoktatást és szinte az egész világot. Számos szerző hangsúlyozza az első egyetemi év jelentőségét (Horn, 1998), hiszen ekkor szocializálódik az egyén az egyetem világába, alakítja ki kapcsolatait a hallgatótársakkal, az oktatókkal és az intézmény egészével (Pusztai, 2011). Továbbá ekkor derülnek ki, hogy a meglévő tanulási módszerek, képességek és anyagi ráfordítások milyen mértékben elegendőek a bennmaradáshoz. Munkámban arra keresem a választ, hogy a továbbtanulás előtt álló középfokú szakképzésbe járó hallgatók körében milyen korai lemorzsolódáshoz vezető kockázati faktorok azonosíthatók, és ezek mennyiben különböznek a gimnáziumból jelentkezőktől. A 2016-os és 2017-es felvételi adatbázisok Dél-Alföld régiójában található középiskolákból jelentkező tanulókat vizsgáltam. Az eredmények azt mutatják, hogy nem minden rizikófaktor tekintetében lehet egyértelműen beazonosítani az intézményi különbséget.
STUDY OF VANCOMYCIN RESISTANCE AMONG STAPHYLOCOCCUS AUREUS

Published: May 2019

Staphylococcus aureus (S.aureus) infections with Vancomycin resistance in hospital complexes are a concern, a significant increase in the number of these occurrences is observed since it is one of the last available antibiotic therapy routes available for the treatment of infectious processes bacterium. Thus, this work aims to present the main mechanism of resistance induction of S. aureus to Vancomycin. The research used the databases Medline, Scielo, the electronic site of the Google Scholar databases as well as specialized magazines in the area. Thus, the selected articles showed that in the late 1950s almost half of S. aureus strains were resistant to penicillin, and in the 1970s the first cases of methicillin-resistant S. aureus (MRSA) appeared; and thus, Vancomycin became employed in such cases. In 1996, the first case of S. aureus with intermediate resistance to vancomycin (VISA) was found. In 2002, the first case of Vancomycin-resistant S. aureus (VRSA) occurred, the latter being the only known to have the VanA gene until then. It was soon discovered that the emergence of this resistance occurred from the transfer of a plasmid with the transposon of the vancomycin resistant vanA, Tn1546 vancomycin (VRE) gene to an MRSA, which already had a plasmid for resistance to gentamicin and production of beta-lactamase. This new plasmid was disseminated to other S. aureus and thus disseminating a new resistance. Thus, the conclusion is that the cycle repeats itself and previously sensitive bacteria become resistant; thus, in this rhythm of emergence of bacterial resistance against antibiotic therapy is worrying, there will be a moment when there will be no antibiotic capable of acting in the fight against bacteria. This shows the need to understand the mechanism of resistance, the discovery of new antimicrobial drugs and the prevention of the spread of resistant microbes.Key words: Staphylococcus aureus, vancomycin, microbial drug resistance, vancomycin resistance.

The impact on production and costs after the acquisition of an airline by a competitor in Brazil: a Cobb-Douglas function application
Authors: Fregnani José Alexandre Tavares Guerreiro , Orra Tarik Hadura , Eller Rogéria De Arantes Gomes , Mattos Bento Silva de
Published: May 2019

O objetivo deste artigo é analisar o impacto sobre os custos de produção e transporte aéreo como resultado da aquisição de uma empresa aérea em crescimento por sua competidora dominante de operação similar. Duas funções Cobb-Douglas, relacionados à produção e custos respectivamente, foram utilizados para tal análise, considerando os períodos anteriores e posteriores à aquisição. Toma-se como exemplo para análise a aquisição da Webjet Linhas Aéreas SA pela GOL Linhas Aéreas Inteligentes, consolidada oficialmente em outubro de 2012. Os resultados demonstram que a aquisição da empresa em crescimento proporcionou impacto negativo na produtividade da empresa dominante, apresentando perda de eficiência operacional, aumento de custos e não absorvendo pleno potencial de produção que a aquisição da primeira pudesse trazer. Tal metodologia demonstrou ser eficaz na análise de impacto desse tipo de operação, uma vez que permite que conclusões baseadas em resultados econométricos sejam utilizadas pelos tomadores de decisão.

Published: May 2019

A produção de petróleo no Brasil tem crescido nas últimas décadas, principalmente em alto mar por meio de plataformas offshore. Dessa forma, faz-se necessário planejar o transporte de suprimentos para essas plataformas utilizando barcos de apoio. Sabe-se que esse transporte tem um forte impacto nos custos das empresas de exploração de petróleo. Dessa forma, esse artigo propõe um modelo matemático baseado no Problema de Roteamento de Veículos Periódico para definição da frota de barcos necessária e de um plano semanal de viagens para cada barco da frota visando o atendimento às demandas das plataformas ao menor custo. O modelo foi testado com instâncias baseadas em dados reais da Bacia Potiguar, sendo utilizado o solver CPLEX para resolve-las. Os resultados alcançados pelo CPLEX foram comparados com o planejamento da empresa e mostraram possíveis ganhos financeiros.
Eficiência dos terminais aeroportuários brasileiros considerando a percepção de satisfação do passageiro
Authors: Negri Nathane Ana Rosa , Ronzani Borille Giovanna Miceli
Published: May 2019

A satisfação do passageiro em aeroportos é tema de grande importância para a comunidade científica e para o operador, dado que o usuário se trata de um importante cliente ao aeroporto. Observa-se, na literatura nacional e internacional, uma tendência em analisar a satisfação do usuário. Porém, é detectada uma lacuna no que diz respeito aos estudos que avaliam a eficiência aeroportuária com inserções de variáveis de percepção da satisfação do passageiro. Nesse contexto, o objetivo do artigo é avaliar a eficiência de 15 relevantes aeroportos brasileiros por meio do método da Análise Envoltória de Dados. O modelo permite analisar diferentes variáveis, sendo a satisfação dos usuários uma dessas variáveis (output). Mediante o modelo DEA-BCC, nota-se que 46,66% dos aeroportos avaliados apresentaram eficiência máxima relativa no ano de 2016, para os requisitos de análise.
Aplicação da metodologia de projeto de experimentos na dosagem de misturas de reciclagem de pavimentos com adição de cimento
Authors: Kleinert Thaís Radünz , Fedrigo William , Ten Caten Carla Schwengber , Núñez Washington Peres , Ceratti Jorge Augusto Pereira
Published: May 2019

Nesse estudo foi verificada a aplicação da metodologia de projeto de experimentos na dosagem de misturas de reciclagem de pavimentos com adição de cimento. Adotou-se um método de dosagem que avalia propriedades mecânicas, volumétricas e de erodibilidade, e foram desenvolvidas todas as etapas que contemplam um projeto de experimentos. O planejamento possibilitou definir as variáveis que exercem maior influência nos resultados, de modo a estabelecer uma matriz experimental abrangente e reduzida. Na análise dos resultados foi possível quantificar o efeito dos fatores controláveis estudados (teor de cimento e porcentagem de fresado) em cada variável de resposta. A partir da otimização multivariada, obteve-se o ajuste ótimo dos fatores controláveis considerando todas as variáveis de resposta simultaneamente. A ferramenta adotada nesse trabalho se mostrou bastante eficiente, podendo ser amplamente empregada na otimização de processos, como é o caso da dosagem de misturas recicladas.
Avaliação das propriedades mecânicas de misturas asfálticas mornas modificadas com adição de óleos vegetais
Authors: Luz Priscila Maria Sousa Gonçalves , Martins Samir Ferreira , Costa Daniel Beserra , Lucena Lêda Christiane .
Published: May 2019

O uso de misturas asfálticas mornas pode vir a diminuir o consumo de energia e da poluição ambiental uma vez que estas misturas possuem temperaturas de compactação e usinagem inferiores às tradicionalmente utilizadas. Esta pesquisa estudou a adição de óleo de milho e de soja, novo e residual, para diminuir as temperaturas de usinagem e compactação das misturas asfálticas. Os corpos de provas foram produzidos em três temperaturas diferentes, a primeira foi à temperatura determinada pelas curvas logarítmicas viscosidade x temperatura e as outras foram 10°C e 20°C inferiores a primeira, respectivamente. Os ensaios mecânicos realizados foram Resistência à Tração, Lottman Modificado, Módulo de Resiliência, Flow Number e Módulo Dinâmico. Os resultados obtidos para os ligantes modificados, com ambos os óleos, foram inferiores aos obtidos para o ligante puro nas mesmas condições de temperatura. Portanto, o uso destes óleos como aditivos só se justifica pela logística reversa do óleo usado.

Se concordarmos que a sustentabilidade é o resultado da forma como a humanidade pode empregar os recursos naturais sem esgotá-los e, assim, viver o presente sem comprometer a vida da próximas gerações no planeta, estaremos concordando que o assunto refere os debates sobre a estrutura dos modos de vida contemporâneo e sua relação com o meio ambiente. Ao propor o tema do número 2 de 2019, a Revista Expressa Extensão buscou reunir reflexões e relatos que pudessem dar conta de estabelecer a relação entre as ações extensionistas e a intensificação da consciência para a sustentabilidade, sem deixar de expressar os conflitos que os atuais modelos de desenvolvimento geraram. Ora, a preservação das formas de vida (da humana, inclusive) e das fontes de energia estão relacionadas com fatores econômicos, éticos, políticos, estéticos e sociais que demandam nossa atenção. Há muito o que ser discutido, e os textos aqui reunidos apontam para questões de diferentes ordens, tanto relatando experiências pontuais como refletindo sobre o papel das universidades sobre um assunto que é inerente ao viver humano, em todas as dimensões. Portanto, afirmamos que o conhecimento gerado na experiência da realidade com as comunidades, pode influenciar nas decisões sobre as políticas ambientais, sobre a produção do alimento, sobre o uso da energia e da propriedade das formas de geração de energia e sobre o modo como percebemos a vida no planeta.
Racial Safety and Cultural Maintenance: The Childcare Concerns of Employed Mothers of Color
Authors: Uttal Lynet
Published: May 2019

When employed mothers of color transfer the care of their children to childcare providers, their needs and concerns reflect their status as members of historically subordinated racial ethnic groups in the United States. This paper introduces two new concepts—racial safety and cultural maintenance—to show how racial ethnic group membership and traditional cultural practices and values are critical concerns that influence the decisions and choices that employed mothers of color make about who will provide care for their children in their absence. This analysis is based on in-depth interviews with Mexican American, African American and Guamanian American employed mothers of infants, toddlers, and preschool-aged children.

This special issue of the journal is on the theme “Ethnicity, Family and Community,” which was the topic of our 23rd annual conference held in March 1995 in Boulder, Colorado. Mary Kelly, our special issue editor, has selected an excellent set of quality articles focused on the theme. Nowhere more than in the field of ethnic studies do the topics of family and community play such important roles. One need only look at the dynamic changes occurring in U.S. society to see how these changes influence and are influenced by ethnic/racial families and the communities in which they reside.

White Ethnic: A Social Concept
Authors: Conforti Joseph M.
Published: May 2019

Why such a term as white ethnic or ethnic developed and what purposes it served guides this inquiry. Its origins in the wake of the Civil Rights Movement in a context of American immigration history are explored together with its adoption as a sociological concept. A survey of textbooks most likely to use such a term, particularly texts concerning race and ethnicity, intergroup relations, and sociology of minorities, together with related literature illustrates both its usage and the basis of such usage.
(Dis)Claiming Identity: Christina García's The Agüero Sisters and Julia Alvarez' How the García Girls Lost Their Accents
Authors: Ögüt Özlem
Published: May 2019

Christine Garcia's The Aguero Sisters and Julia Alvarez's How the Garcia Girls Lost Their Accents are novels that revolve around the conflicts and tensions among the members of the two immigrant families, the Aguero sisters from Cuba and the Garcia sisters from the Dominican Republic, arising mainly from their need to come to terms with their ambiguous identities. This article focuses on the ways in which the Aguero and Garcia sisters through their hybrid identities overcome boundaries and exclusive categories so as to challenge homogenizing, hegemonic systems, and open vistas into new, non-essentialist modes of identity that still can be represented in their specific configurations.
Time is Not a River' The Implications of Mumbo Jumbo's Pendulum Chronology for Coalition Politics
Authors: Nimura Tamiko Fiona
Published: May 2019

Ismael Reed's 1972 novel, Mumbo Jumbo, proposes a unique chronological theory that requires a multiple-grounded understanding of time. An analysis of what could be called this “pendulum” chronology leads to a more complete understanding of the novel and has important implications for a coalition of American ethnic studies and other identity-related work in the academy.
We Both Eat Rice, But That's About It: Korean and Latino Relations in a Multi-Ethnic City
Authors: Han Chong-suk
Published: May 2019

On any given day, in any given restaurant in Koreatown, countless orders are taken, meals are served, tables are cleared, dishes are washed, and checks are paid. Down the street at a corner convenience store, shelves are stocked, beverages are placed into large refrigerators, and purchases are rung up. Even to the most casual observer, it becomes obvious that Korean workers take the orders and collect the money while Latino workers replenish the shelves, clear the tables, and wash the dishes.
Multiple Identities, Citizenship Rights and Democratization in Africa
Authors: Olurode 'Lai
Published: May 2019

This particularistic and exclusionary form of identity politics has intensified in recent years within and among nations…. It is responsible for some of the most egregious violations of international humanitarian law and, in several instances, of elementary standards of humanity…. Negative forms of identity politics are a potent and potentially explosive force. Great care must be taken to recognise, confront and restrain them lest they destroy the potential for peace and progress that the new era holds in store (Kofi Annan, The Guardian, (Nigeria) 1997:8).
The Souls of White Folk: W.E.B. DuBois's Critique of White Supremacy and the Contributions to Critical White Studies
Authors: Rabaka Reiland
Published: May 2019

Traditionally “white supremacy” has been treated in race and racism discourse as white domination of and white discrimination against non-whites, and especially blacks. It is a term that often carries a primarily legal and political connotation, which has been claimed time and time again to be best exemplified by the historic events and contemporary effects of: African holocaust, enslavement and colonization; the “failure” of reconstruction, the ritual of lynching and the rise of Jim Crow segregation in the United States; and, white colonial and racial rule throughout Africa, and especially apartheid in South Africa (Cell, 1982; Fredrickson, 1981; Marx, 1998; Shapiro, 1988). Considering the fact that state-sanctioned segregation and black political disenfranchisement have seemed to come to an end, “white supremacy” is now seen as classical nomenclature which no longer refers to contemporary racial and social conditions. However, instead of being a relic of the past that refers to an odd or embarrassing moment in the United States and South Africa's (among many other racist nations and empires') march toward multicultural democracy, it remains one of the most appropriate ways to characterize current racial national and international conditions. Which, in other words, is to say that white supremacy has been and remains central to modernity (and “postmodernity”) because “modernity” (especially in the sense that this term is being used in European and American academic and aesthetic discourse) reeks of racial domination and discrimination (Goldberg, 1990, 1993; Mills, 1998, 2003; Outlaw, 1996, 2005). It is an epoch (or aggregate of eras) which symbolizes not simply the invention of race, but the perfection of a particular species of global racism: white supremacy. Hence, modernity is not merely the moment of the invention of race, but more, as Theodore Allen (1994, 1997) argues in The Invention of the White Race, it served as an incubator for the invention of the white race and a peculiar pan-Europeanism predicated on the racial ruling, cultural degradation and, at times, physical decimation of the life-worlds of people of color.

The Ties that Bind: Asian American Communities without “Ethnic Spaces” in Southeast Michigan
Authors: Kim Barbara W.
Published: May 2019

According to the 2000 census, over 12 million Asian Americans, almost 70 percent of them either immigrants who came to the U.S. after 1970 or their children, comprised an ethnically and socioeconomically diverse population that was more regionally dispersed throughout the U.S. than ever before. (Lai and Arguelles, 2003). Despite these transitions and increasing heterogeneity, discourses about Asian American communities have focused on ethnic enclaves such as Chinatowns, Koreatowns, and Little Saigons where coethnic residents, businesses, services, institutions and organizations exist and interact in urban or suburban physical spaces of the bicoastal United States (Fong, 1994; Li, 1999; Zhou and Bankston, 1988). According to Kathleen Wong (Lau), these tangible markers tied to space are often privileged as authentic Asian American communities while those without demographic concentrations and geographically bound enclaves are “less advanced” communities; as a result, “[w]hat is not recognized in the literature is the ‘localness' of this production.’ [1997:83].

Understanding outdoor recreation participation and national park visitation by members of ethnic minority groups has been a particular focus of outdoor recreation researchers for the past twenty years. Attracting ethnic minorities, and understanding their recreation needs and interests, demands a multi-faceted approach and sustained commitment not only by the U.S. National Park Service (NPS) but by other resource management agencies as well.
Trey Ellis's Platitudes: Redefining Black Voices
Authors: Manh Ha Quan
Published: May 2019

Trey Ellis has emerged as a prominent African American writer of the late-twentieth century, despite the small number of his published works. “The New Black Aesthetic,” an essay that he first published in CaUaloo in 1989, one year after the publication of his first novel, Platitudes, stands as a manifesto that defines and articulates his perspective on the emerging black literary voices and culture of the time, and on “the future of African American artistic expression” in the postmodern era.1 According to Eric Lott, Ellis's novel parodies the literary and cultural conflict between such male experimental writers as lshmael Reed and such female realist writers as Alice Walker.2 Thus, Ellis's primary purpose in writing Platitudes is to redefine how African Americans should be represented in fiction, implying that neither of the dominant approaches can completely articulate late-twentieth-century black experience when practiced in isolation. In its final passages, Platitudes represents a synthesis of the two literary modes or styles, and it embodies quite fully the diversity of black cultural identities at the end of the twentieth century as it extends African American literature beyond racial issues. In this way, the novel exemplifies the literary agenda that Ellis suggests in his theoretical essay.
Chang-rae Lee's A Gesture Lite: The Recuperation of Identity
Authors: Miller Matthew
Published: May 2019

In Chang-rae Lee's A Gesture Life, the elderly, wellrespected and fastidious Franklin “Doc” Hata begins an introspective journey toward a revitalized and reimagined identity. For Lee, this journey affords the chance to address ethnicity and immigration under a unique transnational context. The novel chronicles how an identity can be recuperated (i.e., healed) through personal and cultural reconnections to the body and to memory. I purposefully use the word “recuperate” in both the traditional and theoretical senses. “Recuperation” results from Hata's moving back into his past to grow forward in self. Simultaneously, he “heals” his self, physically and psychologically, from various “afflictions” he endures. By exploring Hata's various afflictions against the novel's ways to counteract these ailments, I will show how Lee's novel becomes a narrative of recuperation and identity change.
Pachucos, Chicano Homeboys and Gypsy Caló: Transmission of a Speech Style
Authors: Garcia MaryEllen
Published: May 2019

The term caló is well-known within many Mexican American communities as a bilingual slang that is one of several speech styles in the community repertoire, closely associated with Pachuco groups of the U.S. Southwest that came to prominence in the 1940's. But the term caló predates its introduction to the U.S. by many decades. With roots in a Romany-based germanio of the 16th century, from the speech of immigrant gypsies evolved a new Spanish-based argot, the result of language shift from Romany to Spanish over centuries. By the 19th century, caló referred to a Spanish-based criminal argot called “caló jergal” by a contemporaneous Spanish researcher (Salillas 1896), a mixed code of gypsy Romany and Peninsular Spanish which was used by members of that group as an in-group, secret speech style.
Jacob Riis and Double Consciousness: The Documentary/Ethnic “I” in How the Other Half Lives

“Contradictory” is the watchword in scholarship on Danish-American photojournalist Jacob Riis. “Wildly contradictory, morally schizophrenic”: so Keith Gandal describes Riis' work (18). “A deeply contradictory figure […] a conservative activist and a skillful entertainer who presented controversial ideas in a compelling but ultimately comforting manner”: such is the assessment of Riis offered by Bonnie Yochelson and Daniel Czitrom (xv). “The typical Victorian moralist,” but also the Progressive-so Tom Buk-Swienty proclaims him (239, XIII).
Citizenship and Belonging: The Case of the Italian Vote Abroad
Authors: Aliano David
Published: May 2019

The ease in which people are able to travel and communicate with one another across national boundaries is challenging the way in which we identify ourselves and define our place in the world. In an increasingly globalized world the very concept of a national identity is itself being redefined as multiple identities and dual citizenships have become more common than ever. This process of global interconnectedness has progressed so rapidly in the past few years that many are beginning to question how we define national models. The European Union, NAFTA, MERCOSUR, multi-national corporate affiliations, and virtual communities over the internet are all fast creating new collective forms of identity filling a role traditionally associated with the nation-state. These new realities test the limits of traditional citizenship models and challenge us to rethink national identities that transcend borders.
Chicana/Latina Undergraduate Cultural Capital: Surviving and Thriving in Higher Education
Authors: DeMirjyn Maricela
Published: May 2019

This study addressed the retention of Chicana/Latina undergraduates. The problem explored was one; how these women perceive campus climate as members of a marginalized student population and two; which strategies are used to “survive the system.” As a qualitative study, this work was guided by a confluence of methods including grounded theory, phenomenology and Chicana epistemology using educational narratives as data. The analysis indicated that Chicanas/Latinas do maintain a sense of being “Other” throughout their college experiences and this self-identity is perceived as a “survival strategy” while attending a mainstream campus. Further analysis also showed that Chicanas/Latinas begin their college careers with social/cultural capital and is used as a fluid source of support during their stay at the university.
How Are They Racialized? Racial Experiences of Chinese Graduate Students
Authors: Wang Ying
Published: May 2019

The present study explores the lived experiences of Chinese graduate students at a Southwestern University in order to find out how they experience race in daily life, what their interpretations of the racial experience are and how do racialized experiences shape their perceptions of life chances. The results indicate that the racialization process plays an important role in Chinese students' life through their lived experiences. Most Chinese students have noticed race and some of them have experienced racial discrimination. However, Chinese students still hold up the importance of education and believe that education will blunt the racial edge
Chicano/Mexican “Culture” as a Rational Instrument in the Human Sciences
Authors: Gradilla Alexandro José
Published: May 2019

The use of “culture” as an analytical category by social scientists presents an opportunity to examine how professional discursive formations are used to make empirical assertions. The social fact of culture is neither uniform nor unitary. Traditionally, culture has been thought of as a product of disciplinary research, not necessarily a variable for empirical study. When culture is used as a tool or instrument of scientific methodology, it loses its fluid nature as a disciplinary discourse. In this essay, I examine the specific discussion of the epidemiologic health paradox that states that the Chicano/Mexican immigrant “culture” serves as a protective factor against many maladies that afflict other U.S. populations. Since the 1970s, this discussion of culture as a protective factor provides an interesting exposition of the uses of culture by empirical scholars.
The Possibilities of Asian American Citizenship: A Critical Race and Gender Analysis
Authors: Jen Clare Ching
Published: May 2019

Conventionally, citizenship is understood as a legal category of membership in a national polity that ensures equal rights among its citizens. This conventional understanding, however, begs disruption when the histories and experiences of marginalized groups are brought to the fore. Equal citizenship in all its forms for marginalized populations has yet to be realized. For Asian Americans, rights presumably accorded to the legal status of citizenship have proven tenuous across different historical and political moments. Throughout U.S. history, “Asian American” or “Oriental” men and women have been designated aliens against whom white male and female citizenships have been legitimized. These categories of inclusion and exclusion-“citizen” and “alien”-are mutually constitutive; members are legitimate only when defined against the exclusion of “others.” Citizenship must be conceptualized as a broader set of social and cultural memberships and exclusions beyond political rights and legal status. This article examines how scholarly works engage citizenship formations of “Asian American” women and men. It also asks: Are there modes of citizenship, other than legal status and rights, to explain the experiences and histories of Asian American men and women, as well as provide anti-racist, feminist sites of resistance in the struggle for equality?
Examining the Impact of Parental Socialization on the Coping Styles of Black Graduate Students Faced with Microaggressions
Authors: Colbert Robert D. , Perry Kai M. , Anderson Marcia
Published: May 2019

This article explores case examples of two graduate students who endure microaggressions from their math professor at a predominantly White university. The role that parental socialization plays in how these students developed their racial identities and the coping strategies they employed, is analyzed through the lens of Triple Quandary theory (Boykin and Toms 1985). Findings from this investigation suggest that parental socialization is critical in preparing these students to cope with and respond to microaggressions in protective and adaptive ways. This paper illuminates coping styles, although divergent, that served these graduate students' needs and protected their individual racial identities. Further, the support these students received from their faculty advisor who is also Black, exemplifies the importance of mentorship and advocacy from faculty of color to Black college students' success. Direction for continuity in parental teachings for K-12 and university level educators are discussed.
DNA Evidence for a Colonial Jewish Settlement in Appalachia
Authors: Hirschman Elizabeth C. , Vance James A. , Harris Jesse D.
Published: May 2019

Using a 5,000-person DNA database from the Cumberland Gap Region of Appalachia, we document the presence of a Sephardic and Ashkenazic Jewish settlement in Central Appalachia. The settlement may have begun as early as the mid-sixteenth century with the Pardo Expedition and been substantially supplemented from the early seventeenth century onward with Jewish colonists from England, Scotland, and Wales. Additional persons found in this mountainous region show DNA origins from Southeastern Europe, North Africa, South Asia, and the Middle East. Thus the region may have served as a refuge for non-white, non-Christian persons arriving in Colonial North America.

There is an urgent need for more effective strategies to treat ovarian cancer. Elevated cholesterol levels are associated with a decreased progression-free survival time (PFS) while statins are protective. 27-Hydroxycholesterol (27HC), a primary metabolite of cholesterol, has been shown to modulate the activities of the estrogen receptors (ERs) and liver x receptors (LXRs) providing a potential mechanistic link between cholesterol and ovarian cancer progression. We found that high expression of CYP27A1, the enzyme responsible for the synthesis of 27HC, was associated with decreased PFS, while high expression of CYP7B1, responsible for 27HC catabolism, was associated with increased PFS. However, 27HC decreased the cellular proliferation of various ovarian cancer cell lines in an LXR-dependent manner. Intriguingly, ID8 grafts were unable to effectively establish in CYP27A1−/− mice, indicating involvement of the host environment. Tumors from mice treated with 27HC had altered myeloid cell composition, and cells from the marrow stem cell lineage were found to be responsible for the effects in CYP27A1−/− mice. While inhibition of CYP27A1 or immune checkpoint did not significantly alter tumor size, their combination did, thereby highlighting this axis as a therapeutic target.
La formación universitaria de docentes de educación primaria: el caso de matemáticas
Authors: Alpízar-Vargas Marianela , Alfaro-Arce Ana Lucía
Published: May 2019

En este artículo, se hace una descripción de los programas de formación ofrecidos en universidades estatales y privadas de Costa Rica, para obtener el grado de enseñanza en I y II ciclos de la educación general básica. La investigación es cualitativa de corte descriptivo. Se efectuó una revisión documental de los planes de estudio de las diversas universidades y se entrevistaron coordinadores de carreras afines de distintas casas de estudio, así como profesores de matemáticas de estas. El análisis reveló una amplia variedad de dichos programas para formar docentes de educación primaria, sin lineamientos generales y poco control. En Costa Rica, no existen regulaciones sobre el propósito, la duración, el perfil ni los contenidos de estos programas, lo cual podría afectar la enseñanza de matemáticas en las instituciones de educación primaria, ya que llegan docentes con énfasis distintos en su formación.

The outcome of chronic kidney disease (CKD) is frequently development of end-stage kidney failure that requires program hemodialysis (PHD). Increase of the longevity of long-term PHD patients is associated with continuous somatic and psychic stress for the patient, which might adversely affect the quality of life (QoL) of an end-stage CKD patient.

Purpose: to determine the influence of age and dialysis duration on the QoL of end-stage CKD patients receiving PHD.

Materials and methods. 50 patients receiving PHD (23 men and 27 women), aged 31 to 79 years, were examined. The mean age was 56.72±11.26 years. The PHD duration ranged between 1 month to 20 years, the average figure being 5.26±4.82 years. The control group included 50 healthy subjects of comparable gender and age. The QoL evaluation data were gathered through survey using the Russian version of SF-36 Questionnaire (Short Form Medical Outcomes Study), validated by the Institute of Clinical and Pharmacological Studies (Saint Petersburg) and analysis of case records.

Results. As regards the scales of physical health, a decrease of the QoL of PHD patients was found as follows: РF-physical functioning (54.1±25.6 vs. 85.0±21.4), RP-role functioning related to physical condition (38.5±35.4 vs. 74.5±29.7), Pbodily pain (64.7±32.1 vs. 70.5±24.8), GH-general health condition (51.3±15.9 vs. 65.1±21.7). A trend towards inter-group difference was also discovered as regards the scales of vitality (VT) (53.7±19.5 vs. 61.0±19.4), social functioning (SF) (72.5±18.0 vs. 79.5±23.5). Multiple regression analysis established inverse relationship between the patient’s physical health component (PH) and age (rs=-0.317, P<0.05).

Conclusion. In PHD patients, the physical health component is the one that suffers most of all, namely: physical functioning, role functioning related to physical condition, pain intensity, and general health condition. The tendency to statistic differences is observed for the scales of vitality and social functioning of the mental health component. Increase of the age and dialysis duration affect adversely the physical health whereas render no influence on the mental health.
Perioperative Myocardial Damage and Heart Failure in Noncardiac Surgery. Part 1. Etiopathogenesis and Prognosis of Perioperative Cardiac Complications (Review)

Published: May 2019

The purpose of this paper is to provide scientific and practical information on assessment of the risk of myocardical damage development after noncardiac operations (NOMD): ischemia or myocardial infarction (MI), and/or heart failure (HF) and their prevention in adult patients. This overview of literature consists of two parts. The first part analyzes epidemiology, etiopathogeneis, and POCC risk prediction methods; the second part describes the possibilities of adjuvant pharmacological cardioprotection and approaches to optimizing anesthesiological support of operative interventions in high cardiac risk patients.

The problem of perioperative cardiac complications in noncardiac surgey is one of relevant complex issues of contemporary medicine. In line with contemporary views, NOMD is now regarded as a separate variant of a pathological process in the heart muscle. According to extensive studies, about 40% of mortality of adult patients during non-cardial operative inverventions are caused by various NOMD and/or HF. The problem under discussion is particularly relevant when medical assistance is rendered to elderly patients.
