Historia del presente, historia del instante
Authors: Castro Sánchez Emiliano
Published: March 2020

El presente artículo rastrea una falta de sentido histórico y sus implicaciones en la tradición moderna a través de los diagnósticos de Marx, Nietzsche y Heidegger, entre otros. Parto de la crítica de Marx a la falta de sentido histórico en la economía política burguesa y el concepto nietzscheano de “egipticismo” como la idiosincrasia filosófica de valorar lo permanente por encima de lo que deviene. Después, utilizo la imagen del reloj para explorar la relación entre el tiempo y la pérdida de sentido histórico en la modernidad a la luz de pensadores del siglo xx. Posteriormente propongo una posible fuente de dicha falta de sentido histórico en la paradójica relación entre ser y tiempo en Aristóteles. Finalmente, aventuro otra interpretación del tiempo desde la perspectiva del instante en Dogen para mostrar cómo esta “historia del instante” puede transformar la “historia del presente” que hemos rastreado a través del artículo. En mis conclusiones incluyo algunas alternativas filosóficas y políticas de la historia del instante.
Música para la política: Platón y el Pitagorismo
Authors: Vargas Carlos
Published: March 2020

El presente artículo analiza la relación entre música y política en los pensamientos platónico y pitagórico. Se mostrará que, de acuerdo con el platonismo y el pitagorismo, la música afecta de manera fundamental el alma de los individuos, lo cual incide, a su vez, en la organización política. Por consiguiente, se mostrará que ambas corrientes de pensamiento proponen un cuidado especial en la formación musical, con el fin de lograr la adecuada armonía en el alma del individuo. Si es así, también sería posible una relación perfecta entre los individuos y el cosmos. En consecuencia, dicho equilibrio entre los humanos y el cosmos abriría la puerta a la organización de un orden político justo.
Decisions to choose genetically modified foods: how do people's perceptions of science and scientists affect their choices?
Authors: Kim Jiyoun , Fang Sumin
Published: March 2020

This study explores the effects of food science perception on food decisions in the controversial case of genetically modified (GM) foods. We examine (1) how scientific consensus and scientific deference affect the public perception of GM foods; and (2) how perception and healthy eating interest influence people's actual food consumption decisions. We categorized our samples into four groups based on different risk/benefit perceptions of GM food: tradeoff, relaxed, skeptical, and uninterested in the process of further data analysis.
Resource Preservability
Authors: Hsieh Chung-Yun
Published: March 2020

Resource theory is a general, model-independent approach aiming to understand the qualitative notion of resource quantitatively. In a given resource theory, free operations are physical processes that do not create the resource and are considered zero-cost. This brings the following natural question: For a given free operation, what is its ability to preserve a resource? We axiomatically formulate this ability as the resource preservability, which is constructed as a channel resource theory induced by a state resource theory. We provide two general classes of resource preservability monotones: One is based on state resource monotones, and another is based on channel distance measures. Specifically, the latter gives the robustness monotone, which has been recently found to have an operational interpretation. As examples, we show that athermality preservability of a Gibbs-preserving channel can be related to the smallest bath size needed to thermalize all its outputs, and it also bounds the capacity of a classical communication scenario under certain thermodynamic constraints. We further apply our theory to the study of entanglement preserving local thermalization (EPLT) and provide a new family of EPLT which admits arbitrarily small nonzero entanglement preservability and free entanglement preservation at the same time. Our results give the first systematic and general formulation of the resource preservation character of free operations.
Standing Athwart History, Yelling Stop: The Emergence of American Movement Conservatism, 1945-1965
Authors: Bjerre-Poulsen Niels
Published: March 2020

The article analyzes the emergence of the American conservative movement as a postwar reaction to the New Deal order and the new role of the federal government. It discusses the different concepts, and the sometimes conflicting aims of the various strains of the conservative movement, as well as the inherent tension between political populism and the quest for intellectual respectability. It also takes a comparative view of the “Radical Right” of the 1960s and the current “Tea Party movement,” and discusses how the conditions for “ideological gatekeeping” have changed.
Guns on Campus: Surveying a rugged post-Heller/ McDonald landscape
Authors: Lervik Leif Magne
Published: March 2020

In June 2008, the U.S. Supreme Court ruled that the Second Amendment to the U.S. Constitution guarantees an individual the right to keep and bear arms. Two years later, this decision was also made applicable to state and local governments. Today, seven U.S. states have provisions allowing the carrying of concealed weapons on their public senior high school campuses. This article, introduced by a brief comment on the Second Amendment’s legal and academic history, traces several recent developments of legal change. It discusses relevant arguments and attitudes towards guns on campus, and explores issues of future concern for public colleges and universities within the realm of firearms and campus safety.
Living with the Narcos: The “Drug War” in the El Paso-Ciudad Juárez Border Region
Authors: Heiskanen Benita
Published: March 2020

During the years 2008-2012, the El Paso, Texas-Ciudad Juárez, Chihuahua border region between the United States and Mexico saw a wave of violence that occurred as a result of the so-called “drug war” between the Juárez and Sinaloa drug cartels. As the criminal organizations began recruiting local gangs for their enforcement strategies, the violence soon spiraled beyond the context of the drug trafficking industry, generating mayhem and social decay throughout Ciudad Juárez. In four years, the death toll in the city amounted to 10,882, with 3,622 bodies in 2010. This article discusses the impact of the violence in the region as experienced by border residents and in relation to policy responses by the U.S. and Mexican governments. Drawing on fieldwork and interviews conducted in January-May 2010 with members of the border community, it focuses on the interviewees’ experiences in 2010. The discussion of violence is contextualized as a global crisis, with ramifications upon urgent issues of citizenship and political and human rights across national boundaries.
“Purifying the Upper Atmosphere”: Women’s Work in Early Radio, 1905-1913
Authors: Gessler Anne
Published: March 2020

This essay argues that between 1905 and 1913, female commercial radio operators deployed a range of complicated and contradictory arguments to establish credibility in the new, male-dominated communications field. Women envisioned early radio as a utopian space that would renegotiate gender roles in the American workforce. Female radio operators also engaged in a larger conversation around women’s citizenship and voting rights. However, while wireless companies initially hired female employees to diffuse tense labor relations, a national conversation around women’s dubious moral character and inferior physical capabilities soon animated the field. The essay explores the political, economic, and cultural events that transformed radio from a potentially transgressive space to an industry that instead reinforced gender and class hierarchies: the RMS Republic-Florida disaster in 1909; the formation of the wireless division of the Commercial Telegraphers Union of America in 1910; the American Marconi Company’s takeover of the United Wireless Company in 1912; and finally, the RMS Titanic disaster in 1912 and the subsequent passing of the Radio Act of 1912. These events pushed female radio operators out of the industry. Not until World War I would the federal government and corporations formally recruit women to serve as professional radio operators.
On Strike and On Stage: Migration, Mobilization, and the Cultural Work of El Teatro Campesino
Authors: Fielder Elizabeth Rodriguez
Published: March 2020

This essay looks at the role of labor activism through the cultural work of El Teatro Campesino, the theater company that emerged from the farmworkers’ strike led by Cesear Chavez in Delano, California, during the mid-1960s. Through makeshift performances along the picket line, the farmworkers and their creative visionary, Luis Valdez, innovated Chicano/a performance and created an activist aesthetic that has continued to influence Chicano/a performance and art. Their productions, which started as small improvisational actos, drew from a wealth of transnational influences as well as from a larger proletariat and activist theater tradition. However, El Teatro Campesino adapted these techniques to their local resources. The result created a unique forum that enabled promotional education about unions and workers’ rights to exist side-by-side with themes of self-reflection and criticism concerning the risks of identity politics. The essay explores the methods by which El Teatro Campesino questioned and critiqued ethnic identity and argues for a more complex approach to their earlier picket-line entertainment. It proceeds to consider the importance of cultural production for labor mobilization, and argues for a more integrated analysis of the relationship between activism and art.
Differential Health Care Use, Diabetes-Related Complications, and Mortality Among Five Unique Classes of Patients With Type 2 Diabetes in Singapore: A Latent Class Analysis of 71,125 Patients
Authors: Seng Jun Jie Benjamin , Kwan Yu Heng , Lee Vivian Shu Yi , Tan Chuen Seng , Zainudin Sueziani Binte , Thumboo Julian , Low Lian Leng
Published: March 2020

OBJECTIVE

With rising health care costs and finite health care resources, understanding the population needs of different type 2 diabetes mellitus (T2DM) patient subgroups is important. Sparse data exist for the application of population segmentation on health care needs among Asian T2DM patients. We aimed to segment T2DM patients into distinct classes and evaluate their differential health care use, diabetes-related complications, and mortality patterns.

RESEARCH DESIGN AND METHODS

Latent class analysis was conducted on a retrospective cohort of 71,125 T2DM patients. Latent class indicators included patient’s age, ethnicity, comorbidities, and duration of T2DM. Outcomes evaluated included health care use, diabetes-related complications, and 4-year all-cause mortality. The relationship between class membership and outcomes was evaluated with the appropriate regression models.

RESULTS

Five classes of T2DM patients were identified. The prevalence of depression was high among patients in class 3 (younger females with short-to-moderate T2DM duration and high psychiatric and neurological disease burden) and class 5 (older patients with moderate-to-long T2DM duration and high disease burden with end-organ complications). They were the highest tertiary health care users. Class 5 patients had the highest risk of myocardial infarction (hazard ratio [HR] 12.05, 95% CI 10.82–13.42]), end-stage renal disease requiring dialysis initiation (HR 25.81, 95% CI 21.75–30.63), stroke (HR 19.37, 95% CI 16.92–22.17), lower-extremity amputation (HR 12.94, 95% CI 10.90–15.36), and mortality (HR 3.47, 95% CI 3.17–3.80).

CONCLUSIONS

T2DM patients can be segmented into classes with differential health care use and outcomes. Depression screening should be considered for the two identified classes of patients.
Correlation between plume fluctuation and keyhole dynamics during fiber laser keyhole welding
Authors: Li Min , Xiao Rongshi , Zou Jianglin , Wu Qiang , Xu Jiejie
Published: March 2020

In order to reveal the fluctuation mechanism of the plume induced during fiber laser keyhole welding, dynamic behaviors of both the plume and the keyhole were simultaneously observed by using the multiple-imaging method. The results show that the fluctuation period of the plume was the same as that of the laser-induced vapor moving down on the keyhole front wall (KFW). The tilt angle of the plume was the largest when the laser-induced vapor was close to the orifice. As the laser-induced vapor moved toward the bottom of the KFW, the tilt angle of the plume decreased gradually. The correlation between the plume fluctuation and the dynamics of the laser-induced vapor on the KFW was not affected by parameters such as welding speed, laser power, and focal length. Further analysis shows that the periodic drilling behavior of the laser spot on the KFW is the main reason for the periodic fluctuation of the plume.
A Perfect World or an Oppressive World: A Critical Study of Utopia and Dystopia as Subgenres of Science Fiction
Authors: Abdelbaky Ashraf
Published: March 2020

In this article, I investigates the concept of utopia and dystopia in literature since the time of Plato and Thomas More and how it became a significant subgenre of science fiction. I present the kinds of utopia and its fundamental purposes as well as the different explanations for the term utopia and dystopia by numerous critics. I stress the function of science fiction as a literary tool to depict the grim picture and the weaknesses of current societies, dystopias, and to provide a warning for the future of these societies by presenting alternative peaceful societies; utopias. Therefore, I seek to investigate how utopian writings play a central role in uncovering the shortcomings of societies and presenting a formative criticism towards them. I also discuss how utopia and dystopia give women the chance to present their feminist demands using science fiction.
Richard Wright’s Bigger Thomas: Scala d’Amore, Entelechy, and Antinomian Equilibrium in Native Son
Authors: Obed Doku Dr. Samuel
Published: March 2020

Although many critics see Richard Wright’s Native Son as an American classic novel, it is by no means a master narrative that attempts to provide a mega solution to the problems of the black man in American society. Instead, Wright uses the novel to protest against the naturalistic conditions that emasculate a young black man, Bigger Thomas, in 1930s Chicago to commit two murders, one accidentally and the other by design, for which he is sentenced to die.  In his poem, “A Dream Deferred,” Langston Hughes poses a mind-bogglingly critical question: “What Happens to a Dream Deferred?” Thomas, the disturbed protagonist in Wright’s Native Son, has an ambition of becoming a pilot, but fear effaces Thomas’s dream of a better future for him and his mother and presumably, defers his dream to a future date. However, his dream turns into a nightmare, and instead of a pilot, he becomes a cold-blooded murderer. The tension between hope and fear, optimism and pessimism in Thomas is a stark antinomy that should have provided the protagonist a liminal space within which to operate toward a successful resolution of his internal conflict. In this essay, I argue that Thomas’s hope could have propelled him to the pinnacle of success on the scala d’amore to achieve entelechy, but instead, he chooses the antithetical direction, due to his dearth confidence in the system, and that turns out to be tragic.

„Það var eitthvað meira þarna“: Mat á námi með áherslu á vellíðan barna
Authors: Steingrímsson Daníel , Karlsdóttir Kristín
Published: March 2020

Mat á námi og vellíðan barna er hluti af starfi leikskóla samkvæmt Aðalnámskrá leikskóla 2011. Hér verður greint frá rannsókn sem gerð var með sex starfsmönnum eins leikskóla á Íslandi og er hluti af samstarfsrannsókn (e. collaborative action research) sem unnin var í samstarfi RannUng (Rannsóknarstofu í menntunarfræði ungra barna) og fimm leikskóla á Stór-Reykjavíkursvæðinu. Í upphafi auglýsti RannUng eftir þátttakendum sem hefðu hug á að vinna að þróun mats í leikskólum. Í þeim leikskóla sem hér er fjallað um voru þátttakendur aðstoðarleikskólastjóri ásamt tveimur leikskólakennurum og þremur leiðbeinendum á einni leikskóladeild með 24 börnum sem flest voru þriggja ára í upphafi vetrar. Rannsóknin stóð yfir frá september 2016 til maí 2017. Markmið rannsóknarinnar var að starfsfólk ígrundaði eigin starfshætti og þróaði aðferðir við mat á námi og vellíðan barna. Rannsóknargögn byggja á viðtölum og athugunum sem greind voru í þeim tilgangi að sýna ferli framkvæmdarinnar og stöðu þess mats sem fram fór á deildinni. Niðurstöður benda til þess að mat á námi og vellíðan barnanna hafi í upphafi vetrar fyrst og fremst farið fram í samræðum starfsfólks, sem taldi að skráning væri ekki næg í leikskólastarfinu. Það sem metið var í upphafi vetrar tengdist hljóðvitund, málþroska, félagshæfni, hegðun og almennum þroska. Mat þetta fór fram fyrir foreldraviðtöl og í sérstökum tilvikum. Hugmyndir starfsfólks um mat á námi og líðan breyttust yfir veturinn. Starfsfólk fór að fylgjast betur með líðan barna í stað hegðunar þeirra. Þróaðar voru námssögur og var staða barnanna og geta greind og ígrunduð út frá námssögunum. Skráning námssagna reyndist falla vel að því mati sem þegar var framkvæmt á deildinni. Fagvitund leikskólakennaranna skerptist í ferlinu og þeim fannst þeir geta virkjað það sem þeir höfðu áður lært og reynt um börn, áhuga þeirra og líðan. Leiðbeinendurnir töldu sig hafa lært mikið af þátttöku í rannsókninni og þróað faglegri starfshætti, ásamt því að ígrundun um börnin og athafnir þeirra varð þeim tamari. Þátttakendur juku vitund sína um líðan barna og stöðu þeirra innan barnahópsins. Þeir tóku betur eftir börnum sem voru utanveltu í barnahópnum. Samstarfsrannsóknin jók fagvitund jafnt leikskólakennara sem leiðbeinenda, þó kom fram í viðtölum að lærdómur þeirra síðarnefndu virtist enn meiri. Þátttakan í rannsókninni dró athygli þeirra að börnunum, námi þeirra og líðan og gerði þeim kleift að mæta börnunum með því að lesa í tjáningu þeirra. Með þessu móti veittu námssöguskráningarnar þeim nýja innsýn í heim barnanna.

Authors: Duvanskiy V. A. , Vodoleev A. S. , Kriazhev D. L. , Yarotskov I. I.
Published: March 2020

THE OBJECTIVE was to compare the efficacy and rate of complications in patients of groups with uncovered and covered colorectal stents.

METHODS AND MATERIALS. The study included 102 patients who were admitted for emergency with symptoms of malignant colon obstruction, who were randomly installed covered and uncovered SEMS from December 2012 to September 2017.

RESULTS. Clinical success was achieved with uncovered stents in 98 % of cases and 96 % with covered stents (relative risk (RR) 1.02). 95 % confidence interval (CI) 0.954–1.092). The incidence of complications in the group of uncovered stents was 9.8 %, in the group of covered stents – 3.9 % (RR 0.938, CI 0.841–1.046); the frequency of recurrences of obstruction did not significantly different between groups. The median duration of cumulative stent patency was 181 days in the group of uncovered stents and 218 days in the group of covered stents (p=0.427), the difference was statistically insignificant.

CONCLUSION. The use of double covered and double uncovered stents is equally effectively and safely for patients with malignant colorectal obstruction. The frequency of reobstructions did not exceed 4 % and did not differ in the groups of covered and uncovered stents. The choice of the type of stent should be determined individually depending on the clinical situation.

Analysis effects of oil viscosity and temperature on orbit of ring gear in internal gear motor
and pump
Authors: Pham Trong Hoa
Published: March 2020

Effect of oil temperature and viscosity on the ring gear orbit in the internal gear motor and pump is analyzed in this study. The mobility method is used to calculate the ring gear orbit. The mathematical model of oil viscosity and temperature is then integrated into the mobility method. The simulation results point out that the oil temperature and viscosity have great effect on the eccentricity, position angle and minimum oil film thickness. The metal - to - metal contact phenomenon occurs if internal gear motor and pump operates under high values of oil temperature or low values of oil viscosity conditions.
Electron trapping mechanism in a multi-level organic fet memory using lithium-ion-encapsulated fullerene as the floating gate
Authors: Cuong Manh Tran
Published: March 2020

We report on the electron trapping mechanism in a multi-level organic field effect transistor (OFET) memory using Lithium-ion-encapsulated fullerene (Li+@C60) as the floating gate. Based on the estimation of trapped electron number per each Li+@C60 molecule when a programming voltage was applied, the active domain of the floating gate was determined to be the surface of the Li+@C60 domain. An analysis of the cyclic voltammetry indicated that each Li+@C60 molecule can trap electrons at the trapping energy level of -4.94 and -4.49 eV. The number of trapped electron was confirmed by the ultraviolet-visible spectroscopy (UV-Vis).

An experimental and simulation study on the wet-dry action to crack cause of pier concrete
in a tidal river bridge
Authors: Ngo Dang Quang , Mai Dinh Loc
Published: March 2020

An inspection of a tidal river concrete bridge in the Mekong River Delta discovered a large number of map cracks in most piers within the tidal range. These map cracks distribute nearly vertically and horizontally with a distance of about 15 and 20 cm. Many of them have a width over 1 mm and a depth exceeding the thickness of the reinforcement protection concrete layer.
Considering the location and the pattern of cracks, the most acceptable hypothesis on their cause was the strain gradient in concrete induced by the change of moisture content during tide rise and fall, i.e. by the effect of wet – dry action.
To verify this hypothesis, experiments on the time dependent change of concrete moisture content and volume were conducted. Based on the results of these experiments, a computer simulation was performed. The simulated crack map and pattern agreed very well with the observed ones. With the obtained results, it is reasonable to conclude that strain gradient in pier concrete induced by the wet – dry action may one of main causes of cracks in such bridge piers
Valuing Literature: The Picaresque and the Writing Life in Mexico
Authors: Téllez Jorge
Published: March 2020

This article contends that Mexican writers have drawn on the picaresque to ponder what they regard as the precariousness of intellectual labor in Mexico. It analyzes the role that the afterlives of the picaresque have played in the portrayal of writers as disenfranchised and vulnerable subjects, two of the most relevant features of the archetype ofpícaros. In addition, this project also suggests that picaresque narratives embody a discourse of precarity that goes beyond pícaros and applies to all subjects who engage in the production and circulation of literature, turning the picaresque in a suitable form in which Mexican writers can reflect on the value of literature in Mexican society.

Nas últimas duas décadas, a quantidade de estudos dedicados a investigar questões raciais em Machado de Assis aumentou consideravelmente. Recentemente, os estudiosos começaram a abordar mais explicitamente suas opiniões sobre escravidão e raça. Considerando as, relativamente novas, abordagens que adotam a raça como elemento imprescindível para uma melhor compreensão das obras de Machado, este artigo amplia o escopo da discussão por meio de um exame de questões raciais em “Missa do galo” e “Teoria do medalhão”. Usando o conto “Recitatif” de Toni Morrison como ponto de partida, eu examino os contos de Machados a fim de revelar a, até o momento desprezada, importância da questão racial nesses dois contos.

Objetivo: Analisar as publicações voltadas para a importância da sistematização da assistência de enfermagem perioperatória em centro cirúrgico, trazendo de maneira atualizada uma definição do seu papel, espaço de atuação perante o paciente cirúrgico e o reflexo no processo de cuidar. Métodos: Trata-se de uma revisão integrativa, onde foram selecionados 5 estudos nacionais, retirados das bases de dados Scientific Electronic Library Online (SciELO), Base de Dados de Enfermagem (BDENF) e Biblioteca Virtual em Saúde (BVS/ LILACS). Resultados: Observou-se que uma grande parte dos artigos relatam a deficiência e dificuldades do enfermeiro no que se refere a aplicação da SAEP. A segurança dos pacientes e a garantia de uma assistência de qualidade à população é uma problemática em todo mundo. A fim de se evitar interferências negativas na assistência à saúde foram desenvolvidas estratégias que visem essa promoção, a serem realizadas de forma integral e individualizada com a intenção de ajudar no processo de segurança cirúrgica do paciente. Considerações Finais: Constatou-se a importância desse sistema na recuperação do paciente. Diante disso se faz necessário a abordagem de tal tema, a fim de colaborar com estudos futuros.

Objetivo: Relatar caso de abdome agudo obstrutivo por estrangulamento de hérnia diafragmática oculta. Relato do caso: Paciente do sexo masculino, com quadro de abdome agudo obstrutivo, transferido do interior do estado e recebido, após cerca de quatro dias de evolução, em hospital da capital, com dor toracoabdominal intensa, distensão abdominal importante e parada da eliminação de flatos e fezes. Radiografia mostrava formação heterogênea mal definida em tórax. Tomografia computadorizada evidenciou conteúdo intestinal em base de hemitórax esquerdo, associado à distensão exagerada do cólon. Indicada laparotomia exploradora, com redução e correção da hérnia diafragmática com sucesso. Considerações finais: O quadro clínico da hérnia diafragmática varia consideravelmente, dependente da biomecânica do trauma, estado fisiológico e individualidade anatômica do paciente, estágio de evolução, tamanho da hérnia, tempo decorrido do trauma, os quais também determinam sua morbimortalidade. É importante que o diagnóstico e o tratamento sejam realizados de modo precoce a fim de evitar complicações tardias, a exemplo da obstrução e infarto de alça intestinal por estrangulamento.
Grand-reaction method for simulations of ionization equilibria coupled to ion partitioning

Published: March 2020

We developed a new method for coarse-grained simulations of acid-base equilibria in a system coupled to a reservoir at a given pH and concentration of added salt, that we term the Grand-reaction method. More generally, it can be used for simulations of any reactive system coupled to a reservoir of a known composition. Conceptually, it can be regarded as an extension of the reaction ensemble, combining explicit simulations of reactions within the system and Grand-canonical exchange of particles with the reservoir. To demonstrate its strength, we applied our method to a solution of weak polyelectrolytes in equilibrium with a reservoir. Our results show that the ionization and swelling of a weak polyelectrolyte are affected by the Donnan effect due to the partitioning of ions and by the polyelectrolyte effect due to electrostatic repulsion along the chain. Both effects lead to a similar shift in ionization and swelling as a function of pH; albeit for different physical reasons. By comparison with published results, we showed that neglecting one or the other effect may lead to erroneous predictions or misinterpretations of results. In contrast, the Grand-reaction method accounts for both effects on the results and allows us to quantify them. Finally, we outline possible extensions and generalizations of the method and provide a set of guidelines for its safe application by a broad community of users.

CONHECIMENTOS E PRÁTICAS EM SAÚDE BUCAL NA ESCOLA: RELATO DE EXPERIÊNCIAS
Authors: Rodrigues Carlos Alailson Licar , Sá-Silva Jackson Ronie , Rocha Alanna Hevelyn da Silva Gomes da
Published: March 2020

O relato de experiências se propôs a identificar os conhecimentos prévios, as percepções e as práticas voltadas à saúde bucal de alunos de uma escola pública do município de Santa Luzia - Maranhão. Um questionário com roteiro estruturado foi utilizado para a apreensão dos dados. Verificou-se que os participantes demonstraram pouco conhecimento sobre saúde bucal. Nesse sentido, sugere-se a discussão do tema na escola de educação básica a partir da implantação de ações preventivas no currículo, além da necessidade de problematizar e contextualizar, envolvendo práticas pedagógicas integradoras nas quais os alunos possam estabelecer a cultura do cuidado com a saúde.

MECANISMOS DE COMBATE À CRIMINALIDADE TRANSNACIONAL: UMA PERCEPÇÃO DE ANOMIA NO ÂMBITO INTERNACIONAL QUANTO AOS CRIMES AMBIENTAIS
Authors: Ribas Marinho Claudia Margarida
Published: March 2020

A Globalização fez emergir a criminalidade organizada transnacional que se favorece da visão tradicionalista do direito penal, limitada ao princípio da territorialidade e da soberania estatal. A repressão criminal, até então circunscrita aos limites territoriais estatais, não é suficiente para o embate à esse tipo criminalidade o que obrigou os Estados a uniram-se para a aprovação de tratados internacionais para a cooperação jurídica internacional no combate de crimes com tráfico de entorpecentes, armas e pessoas, corrupção e lavagem de dinheiro. Contudo, não há idêntica preocupação nos esforços para a uma colaboração no enfrentamento da criminalidade ambiental transfronteiriça.
Indigenous Insider Knowledge and Prison Identity
Authors: McIntosh Tracey , Coster Stan
Published: March 2020

This article draws on the personal experiences and state documentation of Stan Coster (Ngāti Kahungungu) whose life has been characterised by different forms of state confinement, including over 25 years in prison serving both short and long lags. Through the use of the Official Information Act, Stan recovered state documentation on himself spanning over 40 years. Stan is not a research participant, but a full research collaborator and is engaged in all elements of this paper, so while not a writer he is both auteur and author of this piece. Stan’s story is his own and yet many of its features speak to a much broader collective experience. His prison identity and gang identity can be seen as being both informed and generated by state sponsored activity. By traversing the issues that pertain to the crisis of mass imprisonment, Māori disproportionality in the prison system, the contribution of the state to prison, and gang identity, we look at the possibilities of drawing on knowledge acquired under conditions of state constraint.
Student Activism Against the Neocolonial, Neoliberal University
Authors: Dawson Marcelle
Published: March 2020

The struggle for cognitive justice is an integral part of decolonising education: it seeks to destabilise the grip that Western thought has over the world and pay more attention to other forms of knowledge that have been deliberately marginalised as part of the colonisation agenda. Aotearoa New Zealand is certainly no stranger to debates and struggles regarding the decolonisation of education. The highly revered work of Linda Tuhiwai Smith and the recent collection by Jessica Hutchings and Jenny Lee-Morgan, are just two examples of scholarship that have made significant contributions to scholar-activism in this area. To extend these debates further and link them to a parallel set of critiques about the neoliberal university, I employ the tools developed by the Portuguese sociologist Boaventura de Sousa Santos, who encourages us to engage in both a ‘sociology of absences’ and a ‘sociology of emergences’. The discussion hinges on an example of the recent student protests in South Africa, dubbed by some as the ‘fallist movement’. The student uprisings highlight the mutually constitutive nature of neoliberalism and racism and underscore the need to frame the global struggle against the neocolonial, neoliberal university as an intersectional one. Given that learning from one another’s struggles is a critical aspect of social movement praxis, the use of this example aims to encourage a ‘north-south’ dialogue between scholar-activists in Aotearoa New Zealand and South Africa.
What Divides?
Authors: Walsh Shannon
Published: March 2020

The academic–activist divide does not merely consist of a division between those working within the academy to transform society and those pursuing the same ends through direct action, community organisation, or other forms of political organisation. Rather, at base the academic-activist divide is constituted by ideas around who can think and speak, what counts as thought and speech, and through the assumption that there are supposedly ‘legitimate’ spaces from which thought and speech issue. Thinking through and beyond the academic–activist divide requires questioning the relation between thought and action and challenging their containment within a social order. In what follows, I seek to move beyond the academic-activist divide by drawing on the work of Karl Marx and Jacques Rancière. Far from an inward exercise in political or social theory, the arguments made here have immediate consequences for questions of political organisation in the present moment.

Towards decolonising constitutionalism
Authors: Lockie Georgia
Published: March 2020

2016 saw the publication of two important, but fundamentally divergent, works on Aotearoa New Zealand’s constitutional arrangements. Sir Geoffrey Palmer and Andrew Butler’s A Constitution for Aotearoa New Zealand and He Whakaaro Here Whakaumu Mō Aotearoa, the 2016 report of Matike Mai Aotearoa, the Independent Working Group on Constitutional Transformation. While Palmer and Butler’s vision is one of reforming and strengthening our current Westminster constitutional system, Matike Mai’s is one of transformational, creative change, in which there is room for tino rangatiratanga—substantive self-determination—to be realised. Here, after situating this work theoretically, I explore and contextualise these two texts as they represent, respectively, a modern ideal-typical Pākehā position on constitutionalism in Aotearoa New Zealand, and a critical, Māori constitutional discourse from which this orthodoxy can be interrogated. Through this comparison, I argue that Pākehā constitutional orthodoxy continues to talk past Māori constitutional aspirations because it fails to account for its own ideological and ontological biases, representing itself as occupying a space of reality and neutrality, rather than domination. Because this orthodoxy perceives tino-rangatiratanga claims through this lens of self-affirming bias, it perpetually misapprehends and mischaracterises these claims— as either seeking mere property and management rights (these being already constitutionally provided for), or, if something more substantial, as unrealistic, divisive, and extreme.

Rejuvenating Radical Potential Through Transdisciplinarity
Authors: Ombler Jenny , Donovan Sarah
Published: March 2020

We begin this paper with a brief overview of disciplinarity and transdisciplinarity. Complex problems like climate change are one area where a disciplinary approach might compromise our ability to enact radical new ways of thinking. The concept of wicked problems has been developed to describe these kinds of complex issues. We discuss the concept of wicked problems and consider how transdisciplinarity might be a way of responding to these problems. We then turn to look at the discipline of public health, interrogating its radical potential and identifying ways in which it currently falls short of this potential. Having introduced these concepts, we discuss how art and public health might meet in a transdisciplinary manner, offering some examples of artists who are already working in a way that moves towards transdisciplinarity. We finish with a caution to avoid the instrumentalisation of art in this context.
