Remediation of clay soil contaminated with lead nitrate using washing-enhanced electrokinetic technique
Authors: Karkush Mahdi O. , Ali Shahad
Published: November 2018

The remediation of clay soil contaminated with lead nitrate has been investigated in details by using the electrokinetic technique enhanced by using purging solutions, mid compartment, and washing technique. The intact soil samples are obtained from Al-Ahdab oil field located in the southeast of Iraq. The soil samples are contaminated synthetically with two different percentages of lead nitrate (6.67 and 20g/kg) and kept for 30 days. The mid compartment is used to reduce the existing paths of contaminants from the soil. Purging solutions in the anode, mid, and cathode compartments are used to control the pH value, while the activated carbon is used to prevent the reverse electroosmotic flow from cathode to anode. The main results of electrokinetic experiments, such as variations of electrical current and pH with time, and the accumulated volume of electroosmotic flow are presented and discussed. It is shown that increasing of the concentration of lead causes increase of the electrical current generated during the remediation process. As a consequence, the intensity of chemical reactions occurring in the anode, mid, and cathode compartments are also increased. The removal efficiency of lead from soil samples ranged between 12.4 and 21 %. The washing process is found beneficial in reducing the period of remediation but does not affect the removal efficiency.

Published: November 2018

Osteoarthritis of the talocrural joint accounts for only 4% of cases of degenerative disease of the musculo­skeletal system. Unlike other joints, idiopathic OA of the ankle joint is identified in only 7% of patients. Until the end of the 1960’s, arthrodesis was the treatment of choice in advanced OA of ankle joint. Absolute indi­ca­tions for arthrodesis include irreversible loss of joint anatomy, neurological conditions, advanced osteoporosis and chronic inflammation. Currently, the surgical treatment of ankle joint OA relies on third-generation endo­prostheses of the ankle. Arthroplasty is indicated in patients under 60 years of age with no history of non-ortho­paedic co-morbidities, engaging in little physical activity, with an intact joint axis and satisfactory mobility and non-smoking. This article analyzes the available literature on the results of surgical treatment in patients with osteoarthritis of the talocrural joint treated with arthrodesis or arthroplasty, taking into consideration the strict indications for each of these surgical methods.

Authors: Ligocka Joanna , Patkowski Waldemar , Szparecki Grzegorz , Ostrowski Tomasz , Wiechno Wiesław , Zieniewicz Krzysztof
Published: November 2018

Background: Liver metastases of differentiated thyroid cancers (DTC) are uncommon. Surgery has proved its effectiveness in patients with 131I negative hepatic lesions. Here we present two patients who underwent liver resection for metastases of DTC.
Case presentation: The first patient is a 36-year-old woman who presented with 70 mm large hepatic metastases of papillary thyroid cancer. After treatment of the primary cancer she was disease free for eight years when the elevation of TSH level resulted in the search for metastasis. Notably, the 131I SPECT did not show any lesions. The CT scan visualized 80mm diameter mass within the liver. Histology confirmed metastasis of the thyroid cancer. Lack of iodine uptake and size of the lesion excluded treatment with radioactive iodine. Radical resection of the metastasis was performed with good short and long-term postoperative result. The second patient is the 65-year-old man who was previously treated for follicular thyroid cancer. When iodine negative 70mm diameter metastasis was detected within the liver he was referred for surgery. The right extended hemihepatectomy was performed. In 12-months follow-up he remained stable, with no signs of disease recurrence.
Conclusions: These two cases show that resection of hepatic metastases of DTC is an option even if the lesions are large. Given the effectiveness and safety of liver surgery we reckon that it should be the treatment of choice when is possible. Decision of surgical treatment should be based on analysis of the ability to perform the radical and safe resection.

Admission: The aim of the article was to determine whether activity on social networks can be related to the loneliness of young people.
Methods: The research used a questionnaire of own questionnaire, containing questions with closed and open cafeteria and Polish adaptation De Jong Gierveld’s the scale of loneliness. There were examinated of 63% students in total, including 43 girls (68.3%) and 20 boys (31.7%), aged 12–13 (seventh grade).
Results: The obtained results divided the studied youth into two groups. The first one were people who did not feel loneliness (69.8%), the second group (30.2%) – people experiencing loneliness to a significant and moderate degree. Differences in the compared groups occurred in relation to the amount of time spent on the portals during the day, the number of friends and the length of having an account on social networks.
Conclusions: The obtained results show that young people pointing to satisfaction and satisfaction from social contacts (group A), declared at the same time activity on social networks over 2 hours a day. However, people who lacked contact with others, including lack of a friend (group B), declared using the portals for 1 hour a day. In the compared groups, there were also differences in the number of friends on the portals and in the length of the account. In the other analyzed areas, there were no differences in the compared groups.

A deposição e decomposição de serapilheira em ecossistemas florestais pode variar com a idade e no decorrer do ano. Este trabalho tem por objetivo avaliar a deposição de serapilheira e quantificar a transferência de nutrientes ao solo ao longo do ano em povoamentos jovens de Eucalyptus dunnii Maiden. O estudo foi conduzido em Bocaina do Sul, SC, sobre um Cambissolo Húmico. Os tratamentos consistiram de avaliações em povoamentos de um, dois e três anos de idade. Em cada povoamento foram instaladas três parcelas e realizadas coletas mensais da serapilheira, utilizando 11 coletores de 0,25 m2 em cada parcela. Foi quantificada a deposição de matéria seca de cada componente da serapilheira (folhas, ramos e casca), e determinado os teores de P, S, K, Ca e Mg. Os três povoamentos apresentaram deposições anuais semelhantes de serapilheira, sendo cerca de 95% da biomassa representado pelas folhas. A deposição de serapilheira foi sazonal, com menor deposição no inverno e maior no verão. As folhas foram o principal contribuinte na transferência de nutrientes, transferindo em média 99% do P, 97% de K, 97% de Ca, 96% de Mg e 98% de S. A magnitude de transferência de foi: Ca > K > Mg > S > P.
Kant and the Crusians in the Debate on Optimism
Authors: Krouglov Alexei N.
Published: November 2018

In this article, which completes a two-part series on the problem of optimism in Kant’s works, I explore in detail the arguments advanced by the Crusians A. F. Reinhard and D. Weymann against the actual world as the best of all possible worlds and in favour of the actual world as one of the good worlds, Kant’s counterarguments put forward in the mid-1750s drafts and in An Attempt at Some Reflections on Optimism (1759), and further polemical attacks on this topic against Kant by D. Weymann in his works of 1759—1760. I trace the evolution of Kant’s views on optimism from the mid- to the late-1750s, when this concept — once characteristic of the partly unacceptable position that G. W. Leibniz defended in the Theodicy — came to describe Kant’s own views. Leaving aside Voltaire’s resonating works on the Lisbon earthquake, the generic opponent to Kant’s position is an amalgam of Crusians (C. A. Crusius, A. F. Reinhard, D. Weymann, and others), reduced to a caricature with regards to certain theses. I address Weymann’s polemic with Kant to show that, in the pre-critical period, the early Kant advocated beliefs in sphere of practical philosophy that he later radically changed in the critical period, in particular those with regards to freedom and human dignity. The obvious bias of most Kantian scholars against Kant’s opponents prevented researchers from seeing the validity of Weymann’s criticism of Kant for ignoring the problem of freedom. To prove his point, Weymann addressed the difference between the freedom of contradiction (libertas contradictionis) and the freedom of contrariety (libertas contrarietatis). Apparently, Kant himself noticed to a certain degree the validity of Weymann’s criticism, since, after 1759, he abandoned the term “optimism” and, in his later years, distanced himself from his early work An Attempt at Some Reflections on Optimism.

Na produção de hortaliças de qualidade a formação de mudas é uma das fases mais importantes para o ciclo da cultura, influenciando diretamente no desempenho final da planta, tanto do ponto de vista nutricional como produtivo. Um dos fatores decisivos para obtenção de mudas com qualidade e consequente aumento de produtividade é o tipo de substrato utilizado. O estudo objetivou avaliar o efeito de proporções crescentes de resíduos da secagem de grãos de café (moinha) em substratos alternativos compostos de fibra de coco, casca de ovo e substrato comercial, nas variáveis de crescimento de mudas de repolho. O delineamento experimental foi o inteiramente casualizado, com cinco tratamentos e dez repetições, sendo os tratamentos: T0: substrato comercial (testemunha); T1: 10% de moinha (MO) + 15% fibra de coco (FC) + 5% casca de ovo (CO) + 70% substrato comercial (SC); T2: 20% de MO + 15% FC + 5% CO + 60% SC; T3: 30% de MO + 15% FC + 5% CO + 50% SC; T4: 40% de MO + 15% FC + 5% CO + 40% SC. As variáveis avaliadas foram condutividade elétrica do substrato, diâmetro de coleto, número de folhas, altura de plantas e matérias secas da parte aérea, raiz e total de planta. Os maiores valores obtidos das variáveis analisadas foram obtidos no tratamento 4, no qual se utilizou-se 40% de moinha + 15% fibra de coco + 5% casca de ovo + 40% substrato comercial.

O Estado de Minas Gerais é um grande gerador de resíduos provenientes da fabricação de derivados do leite, onde o reaproveitamento da água residuária desse processo além de servir como fonte de nutrientes, pode evitar poluição de água e do solo. O objetivo do trabalho foi o reaproveitamento da água residuária de laticínio para a formação de mudas de mamoeiro, considerando suas necessidades hídricas no período de formação de mudas. Foi utilizado o esquema fatorial 5 x 2, em delineamento em blocos casualizados, sendo os fatores: concentrações de água residuária de laticínio (0, 25, 50, 75 e 100%) e dois tipos de substratos, Bioplant® e uma mistura de terra, areia e esterco bovino, na proporção 2:1:1, com quatro blocos e oito plantas por parcela. Após 60 dias, foram avaliadas as seguintes características: comprimento da parte aérea e do sistema radicular (cm), número de folhas, diâmetro do caule (mm), matéria seca da parte aérea e do sistema radicular (g) e análise de macro e micronutrientes presentes nas plantas. O maior desenvolvimento das mudas de mamoeiro ocorreu com a aplicação da água residuária de laticínio na concentração de 100% quando utilizada com o substrato composto por solo, areia e esterco bovino, suprindo as necessidades hídricas e nutricionais na formação das mudas de mamoeiro.

Objetivou-se nesse estudo estimar a distância genética com base em distintos caracteres fenotípicos e descritores agronômicos, em experimentos a campo, em casa de vegetação e análise conjunta de ambientes em arroz irrigado. Neste estudo foram avaliados 16 genótipos de arroz irrigado em experimentos a campo e em casa de vegetação. Nas duas condições experimentais foram mensurados 24 caracteres, sendo, 16 considerados quantitativos e oito considerados qualitativos. A partir dos dados fenotípicos foram obtidas três matrizes de distâncias de Mahalanobis (baseadas nos caracteres mensurados a campo, casa de vegetação e análise conjunta), que posteriormente originaram três dendrogramas, utilizando o método de agrupamento das médias das distâncias (UPGMA – Unweighted Pair Group Method using Arithmetic averages). A associação das matrizes de distância genética foi realizada pelo teste de Mantel. Assim, as estimativas da distância genética utilizadas, mostraram-se adequadas no agrupamento dos genótipos, evidenciando estreita distância genética entre as cultivares de arroz irrigado avaliadas. As matrizes de distância genética entre os genótipos com base nos caracteres qualitativos aferidos a campo, em casa de vegetação e a conjunta de ambos os ambientes, evidenciaram associação elevada entre si. Existe efeito do ambiente em caracteres de herança genética quantitativa.

O objetivo deste trabalho foi avaliar a produtividade e qualidade de grãos sob distintas densidades de semeadura em híbridos de arroz irrigado. Os experimentos foram conduzidos nos municípios de Capão do Leão e Capivari do Sul, no Rio Grande do Sul. Os híbridos BRSCIRAD 302 e BRSCIRAD AH703 CL foram analisados, nas densidades de semeadura de 10, 20, 30 e 40 kg ha-1, para os caracteres: produtividade e componentes de produção de grãos, características agronômicas, qualidade industrial e comercial de grãos de arroz irrigado. Os dados foram submetidos à análise de variância e ao teste F utilizando-se para a comparação dos híbridos o teste de Tukey nível de significância de 5% e para densidade de semeadura foi aplicada a análise de regressão. A partir da densidade de semeadura de 20 kg ha-1, não há efeito sobre a produtividade. A qualidade industrial de grãos dos híbridos não é influenciada pela variação na densidade de semeadura e a redução na densidade de semeadura para até 10 kg ha-1 não prejudica a qualidade comercial dos grãos. Assim, é possível recomendar o cultivo de híbridos de arroz irrigado com densidades reduzidas de semeadura, a partir de 20 kg ha-1, não afetando a produtividade de grãos e a qualidade dos grãos.

Sistemas agroflorestais são opções para a intensificação sustentável da produção agropecuária, sobretudo em regiões que apresentam clima tropical e solos arenosos. Objetivou-se nesse trabalho avaliar o desempenho da cultura da soja em sistemas agroflorestais com Eucalyptus urograndis na região Noroeste do Paraná. Os sistemas foram implantados em outubro de 2009, usando renques simples e duplos de eucalipto. O desempenho da cultura da soja foi avaliado na safra 2015/16, em quatro experimentos. Em cada experimento foi utilizada uma conformação espacial de plantas de eucalipto: renques simples com baixa densidade de árvores, renques simples com alta densidade, renques duplos com baixa densidade e renques duplos com alta densidade. Como testemunha, foi considerada uma área contígua, sem a presença de árvores. Nos quatro experimentos, o crescimento e o teor de nitrogênio na massa seca da soja, avaliados no pleno florescimento, não foram reduzidos expressivamente em função da interferência do eucalipto. A redução de produtividade de grãos de soja causada pelas árvores variou de 40 a 43% em relação à testemunha. Os teores de proteína e óleo nos grãos de soja não foram alterados pela interferência das árvores.

A formação de mudas frutíferas é uma fase importante da cadeia produtiva da fruticultura e na citricultura não é diferente, sobretudo na produção de mudas de qualidade. O uso de fontes alternativas de nutrientes minerais ofereceria novas opções de produto para fertilização aplicadas à agricultura moderna. Este trabalho teve como objetivo avaliar o crescimento e desenvolvimento de mudas de limoeiro 'Cravo' submetidas à aplicação de complexo hidrossolúvel em diferentes concentrações como fonte alternativa de nutrientes minerais. O experimento foi conduzido entre os meses de novembro de 2012 a abril de 2013, cujas mudas foram formadas em tubetes durante 150 dias. O complexo hidrossolúvel (CH) foi aplicado em cobertura mediante irrigação mensal com soluções nas concentrações de 0, 1, 2, 4 e 8 g L-1 sobre as mudas com ou sem adubação química convencional. As características avaliadas foram altura, diâmetro do colo, número de folhas, comprimento de raiz, massas fresca e seca da parte aérea e do sistema radicular, comprimento total de raízes e volume radicular. O CH influenciou na altura e diâmetro das mudas de limoeiro 'Cravo', cujas estimativas concentrações entre 4 e 8 g L-1 tenderam a promover melhores resultados. A adubação de cobertura com o CH associado à adubação química convencional promoveu melhor formação radicular em comprimento e volume, exceto quando se aplicou de 8 g L-1 do CH.

Para modelos fidedignos de estimação de área foliar, é importante que as estimativas de seus parâmetros sejam precisas, e, para isso, devem ser geradas com número adequado de folhas. O objetivo deste trabalho foi determinar o número de folhas necessário para modelar a área foliar de mucuna cinza (Stizolobium cinereum) determinada por fotos digitais (Y), em função da largura do limbo do folíolo central da folha (x), por meio do modelo potência (Y=axb), gerado por processo iterativo. Em seis períodos de desenvolvimento da cultura (29, 43, 57, 73, 87 e 101 dias após a emergência) foram coletadas, aleatoriamente, total de 790 folhas. Cada folha é composta pelos folíolos esquerdo, central e direito. Foi mensurada a largura do limbo do folíolo central (x) e determinada a área foliar (soma da área dos folíolos esquerdo, central e direito) por meio do método de fotos digitais (Y). O número de folhas, necessário para a estimação dos parâmetros a e b do modelo potência e do coeficiente de determinação do modelo (R2), foi determinado por reamostragem, com reposição. Em mucuna cinza, o modelo potência (Ŷ=4,4019x1,8697, R2=0,9821) da largura do limbo do folíolo central (x) é adequado para estimar a área foliar obtida por fotos digitais (Y). Mensurar 240 folhas é suficiente para construção de modelos precisos do tipo potência, da área foliar de mucuna cinza determinada por fotos digitais (Y) em função da largura do limbo do folíolo central da folha (x).

A energia elétrica é fundamental nos dias atuais, mas para chegar até empreendimentos agroveterinários, bem como ao consumidor final, há necessidade da implantação de empreendimentos que podem impactar o meio ambiente. Neste sentido, a avaliação de impactos ambientais desempenha um importante papel, contribuindo para que o desenvolvimento econômico e social estejam aliados aos fatores ambientais. Este estudo tem como objetivo avaliar por meio do método Ad Hoc, bem como de ambas as matrizes de interação e ponderação de atributos os impactos gerados por uma subestação de energia elétrica, situado no município de Palhoça, Santa Catarina. Foram analisadas as atividades relacionadas às etapas de implantação do empreendimento que consistem na terraplanagem, quando necessário e, posteriormente, as atividades de construção civil. Finalmente, a etapa de operação do empreendimento que consiste na identificação das ações geradoras que são as atividades de terraplanagem, locação e construção de estruturas, escavações, sistemas de drenagem e aterramento, montagens eletromecânicas, mobilização de pessoal e manutenção da subestação e consequentemente os impactos ambientais. As atividades realizadas pelo empreendimento em questão que podem afetar de forma direta os aspectos ambientais como: água, solo, emissões atmosféricas, entre outras, além de aspectos sociais. Com a utilização das matrizes de ponderação e interação, foi possível diagnosticar que a maioria das atividades impactantes ocorre na fase de implantação do empreendimento. A maioria dos impactos, para o empreendimento selecionado, foi classificado como de pequena importância, baixa magnitude e reversíveis. Este estudo de caso poderá auxiliar futuras pesquisas e estudos ambientais nas mais diversas áreas, de modo a apresentar um método de demonstrar a importância e interação de cada impacto, além de evidenciar para os órgãos licenciadores um método alternativo o qual pode ser exigido para os futuros estudos de impacto ambiental.

A pesquisa teve como objetivo avaliar os efeitos da maturação a vácuo sobre as mudanças de qualidade dos bifes de bovinos até 9 dias de refrigeração. O músculo Longissimus dorsi de 20 bovinos cruzados (Charolês x Angus) foram utilizados na pesquisa. As amostras foram distribuídas em três períodos de maturação a vácuo: T0 = zero (sem vácuo), T3 = 3, T7 = 7 e T9 = 9 dias, com cinco repetições, em cada período avaliado. Durante o período de maturação foi determinado o pH, a coloração (L*, a*, b*), tonalidade, croma, capacidade de retenção de água, perda por cocção e força de cisalhamento das amostras. Verificou-se que o progresso da maturação da carne a vácuo altera (p<0,05) o croma, a tonalidade, e a força de cisalhamento. Os demais parâmetros avaliados não apresentaram modificações significativas durante as avaliações. De acordo com os resultados, pode-se afirmar que o período de maturação até 9 dias influencia na qualidade instrumental da carne bovina, ou seja, um período inferior ao recomendado pela indústria para maturação da carne, que por sua vez, influencia na decisão de compra dos consumidores.

Foram realizadas três coletas, com intervalos regulares de aproximadamente 30 dias no período reprodutivo de 2012/2013. Foram utilizados dez reprodutores de no mínimo três anos de idade. Para a coleta de sêmen foi realizada indução hormonal com extrato de hipófise de carpa, e a extração do sêmen ocorreu por massagem abdominal. Após coleta, o sêmen foi submetido a avaliações de motilidade, vigor, tempo de vida, volume do ejaculado e concentração espermática. As variáveis quantitativas foram submetidas à análise de variância (ANOVA) e teste de Tukey, e as variáveis qualitativas ao teste de Friedman, com significância de 0,05. Não foram observadas diferenças significativas (p>0,05) para a maioria dos parâmetros avaliados. A concentração espermática variou significativamente entre as coletas (14,5, 3,7, e 8,3x109 espermatozoides/mL) e o tempo de vida diminuiu significativamente entre a segunda e terceira coletas (267,8 e 98,5 segundos, respectivamente).
The roads more or less traveled - A sequence analysis of family formation and parenthood for a cohort of Danish women born in the 1970s
Authors: Steffensen Tinne
Published: November 2018

Relatively low fertility and an increased age at first birth, along with the development of assisted reproduction technologies have increased attention to when and how many times Danish women give birth. While some argue that family formation has become increasingly plural and differentiated, others maintain that the nuclear family remains the ideal family for the majority of women. In this article, I investigate family formation trajectories for a random sample of 1,500 women born in 1973 and 1974. For this sample, I perform sequence analysis of longitudinal registry data on civil status, fertility, education and income through the ages 22 to 37. Focusing on timing, order and duration in the sequences studied, I identify seven distinct clusters (i.e. typologies) of family formations in Denmark. The majority (68 percent) of the women’s trajectories represent varieties of the nuclear family. For all clusters, my results confirm the event of the first child as a constituting factor of the nuclear family, which often precedes marriage. However, the identified clusters also show great variation when it comes to age at birth of first child, socio-economic status and overall turbulence in their trajectories.

footnotes and marginalia

Published: November 2018

Disability or lack of health present areas of unthinkability not only to our surroundings, but to ourselves. In “footnotes and marginalia” I explore my horizon and blind spots through an analysis of James Blish’s More Light, a horror story about infectious reading. Deliberately blurring the lines between genres, my text is itself infected with horror elements and becomes a horror story, twisted and outrageously wrong. As the title implies, it deals with what happens at the borders of academic inquiry, exploring embodiment and how to approach the parts of our horizons we cannot look straight at. Interested in reception on the smaller scale as well as the larger, it probes the back-and-forth between reader and text. Working with texts we all let the text into us, letting it infect us, change our inner landscapes. I include a rather detailed sensory descriptionof such a reading process, and I hope to encourage sensory awareness in the reader as well. I hope to make you tense up and feel uneasy. I hope to make you laugh. I hope to make you flinch. In short, I hope it is as unpleasant to read as it was to write.
Monsters Escaping the Screen: Embodied Narratives of LARPS and Zombie Walks
Authors: Stenström Kristina
Published: November 2018

This article engages with communities that invite monstrous characters to come to life and invade three-dimensional spaces through real-life bodies. Through focus group interviews with participants in live action role-play (LARP) and zombie walks in Stockholm, this text explores the ways in which participants engage in physical encounters with monstrosity and the surrounding narrative worlds. First, I address how monstrous corporeality not only functions as fiction or escape but most concretely taps into contemporary discourses connected to corporeal change. Through Butler’s performativity and becoming and in connection with discourses of makeover culture, I argue that both LARPs and walks function as both performances and performative acts in which demands connected to idealized corporeal transformation may be concretized,reenacted and renegotiated. Second, the monstrous body here functions simultaneously as an embodied narrative device and a medium. Participants compare the emotional and physical experience of LARPing and zombie walking to that of consuming popular cultural texts in horror or thriller films and television. However, an aspect of zombie walks and LARPs is the concrete physical transformation of those who participate. Furthermore, the use of masks, clothing and jewelry all add tactile dimensions to (or enhance these dimensions in) an embodied experience of a story-world of monsters.

We met with Nina Lykke in Copenhagen, in orderto let her unfold how her own interest in Feminist STS/Feminist Technoscience Studiesemerged, and how she has put feminist cultural studies of technoscience to work from the1980’s until today, through research, teaching, and activism.
The trouble of sex: Sex-determination, prenatal diagnosis and politics
Authors: Lindén Lisa , Ljungberg Helena Tinnerholm
Published: November 2018

Recent decades have seen the rapid development of assisted reproductive technologies (ARTs) and methods of prenatal diagnosis. As a result, there are now several ways to predict the genetic sex of embryos as well as visualizing the sex of fetuses. However, how, when and where these technologies may be used have become politicized questions, both internationally and in Sweden. By providing a close reading of the Swedish political debate about technologies for the determination of the sex of fetuses and embryos from the end of the 1980s onwards, this article shows how technologies of prenatal diagnosis are articulated as problematic in the context of sex-determination. By “staying with the trouble” of sex in the political debate about sex-determination, we discuss how the ability to identify fetal or chromosomic sex through prenatal diagnosis is articulated as an unwanted trouble warranting political and ethical concern. The article also highlights the “ethico-political” restrictions imposed on information about the unborn’s sex. It shows that, rather than prenatal diagnosis enabling promissory or hopeful visions of the future, the political debate is preoccupied with feelings of concern about the potential misuses of these technologies.
Olie som misfittende relation: En nymaterialistisk analyse af det sorte gulds klæbrige karaktertræk i Inferno (2014)
Authors: Rosenbæk Karl Emil
Published: November 2018

Oil as a misfitting relation. A new-material analysis of the black gold’s sticky character in Inferno (2014)The article examines Ida Marie Hede’s novel Inferno (2014) through the lens of new materialism’s theoretical interest in matter and materiality. By focussing on the actions of oil in the novel the article shows how seemingly ‘dead’ and finite non-human objects express liveliness. Oil influences, affects, creates, and disrupts, in a word acts, on its surroundings. And due to the global-political relations oil is entangled in, oil seems particularly inclined to produce a certain effect – a disabling misfit between ecosystems. Therefore, although the article pivots around Inferno, it also tries to connect this idea of non-humane liveliness to the socio-political reality of climate change. Perhaps the realisation of a global “planetan misfit” is a necessary first step towards an ontological reconceptualization: A move from substances to relations as the ontological base. Philosopher Rosi Braidotti proposes the term process-ontology. This article uses that concept as a guiding principle when it reads Inferno. What does oil do and what is done to oil – in and outside the novel?
Idealized Nationalism in Downton Abbey
Authors: Aakjær Christa Rydeberg
Published: November 2018

With the Downton Abbey series as a starting point, this study examines how fictional media is a new source of renegotiating national identity, in this case Englishness. A close analysis of Downton Abbey and similar cultural phenomena shows how heritage film modify and idealize certain aspects and values of history to alter and ultimately rewrite the memory of history. Different definitions of nationalism and identity are explored to lay the basis of a discussion of why Downton Abbey appeared when it did and how fictional productions of history and culture might key to the recreation of contemporary cultural identity. Thus, this article will reveal the connection between the popularity of heritage productions and their impact on the cultivation of cultural identities and national sentiments.
Challenging or Conforming to the Norms of Victorian Society
Authors: Arildsen Emilie
Published: November 2018

Queen Victoria represents a personality split between the values of the submissive contemporary woman and the values of a powerful monarch. She was head of her country, but a married woman too, and this combination entailed situations that were difficult to navigate while retaining the values of the ideal Victorian woman and simultaneously meeting her duties as queen. I claim that by combining her two roles and becoming the mother of the Empire, Queen Victoria ultimately bettered women’s social status by influencing the mindset of her contemporary women. Her influence is apparent in writings of both feminists such as Millicent Garrett Fawcett and conservative Sarah Stickney Ellis as well as in the lives of her own daughters.
Physical Activity in Mathematics Education
Authors: Rottmann Thomas , Bayer Friederike
Published: November 2018

The term “Learning through Physical Activity” is used to describe learning processes in which whole-body movement is strongly linked to the learning content. Although this way of learning is generally accepted and its positive impact on the learning process is theoretically grounded, ideas for the practical application in mathematics education in Germany are largely missing, as is any corresponding scientific research. This paper aims to close this research gap. In order to do so, movement games, which support the development of “Grundvorstellungen” of multiplication, were developed and scientifically evaluated using a pre- and post-test design during a teaching unit in a mixed-age group.

In this appendix to M. S. Christensen, “Regularity of Villadsen algebras and characters on their central sequence algebras”, Math. Scand. ?? (????), ???--???, we prove that the Villadsen algebra $\mathcal{V} _\infty $ does not satisfy the Corona Factorization Property (CFP).
Orbit equivalence of graphs and isomorphism of graph groupoids
Authors: Carlsen Toke Meier , Winger Marius Lie
Published: November 2018

We show that the groupoids of two directed graphs are isomorphic if and only if the two graphs are orbit equivalent by an orbit equivalence that preserves isolated eventually periodic points. We also give a complete description of the (topological) isolated points of the boundary path space of a graph. As a result, we are able to show that the groupoids of two directed graphs with finitely many vertices and no sinks are isomorphic if and only if the two graphs are orbit equivalent, and that the groupoids of the stabilisations of two such graphs are isomorphic if and only if the stabilisations of the graphs are orbit equivalent.
Non-Koszul quadratic Gorenstein toric rings
Authors: Matsuda Kazunori
Published: November 2018

Koszulness of Gorenstein quadratic algebras of small socle degree is studied. In this paper, we construct non-Koszul Gorenstein quadratic toric ring such that its socle degree is more than $3$ by using stable set polytopes.
On decay centrality in graphs
Authors: Coroničová Hurajová Jana , Gago Silvia , Madaras Tomáš
Published: November 2018

The decay centrality of a vertex $v$ in a graph $G$ with respect to a parameter $\delta \in (0,1)$ is a polynomial in δ such that for fixed $k$ the coefficient of $\delta ^k$ is equal to the number of vertices of $G$ at distance $k$ from $v$. This invariant (introduced independently by Jackson and Wolinsky in 1996 and Dangalchev in 2011) is considered as a replacement for the closeness centrality for graphs, however its unstability was pointed out by Yang and Zhuhadar in 2011. We explore mathematical properties of decay centrality depending on the choice of parameter δ and the stability of vertex ranking based on this centrality index.
“PLEASE LEAVE A MESSAGE”: THE MEDIA ECOLOGY OF RUBEN ÖSTLUND’S PLAY, FORCE MAJEURE, AND THE SQUARE
Authors: Lynch John
Published: November 2018

This article examines three films by the Swedish director Ruben Östlund: Play (2011), Force Majeure (2014), and The Square (2017). It describes the role of mobile phones in the films, both on the level of content and in terms of aesthetics. Within the films, the failure of the phone to connect the protagonists to significant others is seen as symbolic of an alienation that leads them to points of crisis. Here, the mobile phone works as a device in two ways. First, as a significant communication technology, and second, as a plot contrivance to advance the dramatic conflict. Critically, the mobile phone opens an uncertain space where subjectivity becomes increasingly insecure, precisely as it becomes fundamentally intertwined with it. There is a cinematic tradition of mobilizing this ambiguity to which this process can be connected. Further, the form of these works is considered in relation to the notion of traumatic repetition, and how this expands into the wider contemporary image-culture and the key influence of YouTube within this. Here, the films are considered in relation to the changing dynamic of the public sphere in the light of the mobile recording capabilities, that have come to shape an emergent cinematic aesthetic evident in these films.
Modalities or Surfaces
Authors: Tapper Janne
Published: November 2018

This article will examine the playing with aesthetical surfaces in postmodern theatre and how itreflects the poetics and the cultural logic of late capitalism. Surfaces are examined as aestheticelements of the postmodern culture of the image. This culture is not neutral as it seems toreject the modern spiritual depth, for instance, sense of history and hermeneutic depth. Thearticle examines the riddle concerning how the absence of these aspects of human thought insurfaces generates the spectators' need to produce coherent individual activities, trajectories,and eventually acoherent culture. This reflexive mechanism of surfacesis analyzed within theframework of Donald Norman's (2005) cognitive principles of design. Starting from thepremise of Gilles Deleuze's and Felix Guattari's (1987) and Lev Vygotsky's (1978) notions ofplay, it is interpreted that postmodern stage and culture works, metaphorically, like the plane ofimmanence, the way of thinking in which an agent is able to move, make transitions andcrossings in a revolutionary way without restrictions of reality's conditions. However,culturally the blurring of boundaries between play and reality may lead to delirium andill-founded practices. Theatre and art examine these ill-founded practices but involve in theirpoetics a strong dimension of reflexive level of human cognition. This reflexive level is anexplanatory perspective, which helps spectators examine theatre's mechanisms as metaphors ofcultural logic, to achieve a critical position extrinsic from the flux of postmodern culture. Thispoetics is examined in several cases of theatrical representation including Sofia Coppola's filmThe Bling Ring (2013), The Need Company's production The Lobster Shop (2006), KristianSmeds' production The Unknown Soldier (2007) and in several casesof postmodern art and stagedesign.
The Influence of Natural Monopolies on Cultural Democracy in the Performing Arts in Estonia
Authors: Karulin Ott
Published: November 2018

The core question of this article is to what extent has the state set securing cultural democracy (vs. the democratisation of culture as defined by François Matarasso and Charles Landry1[1]) in the performing arts in Estonia as its policy goal. In Estonia, the theatre field is dominated by natural monopolies. These are companies that receive most of the financial subsidies in a respective field, making it economically non-viable for any other company to duplicate these resources. In Estonia, there are eight state-owned theatres (called G8-theatres) that collect, on average, 60% or more of the state subsidies for theatres, the state-subsidized theatre visits and the total income from ticket sales. As stated in the Competition Act of Estonia, company or companies that earn more than 40% of the turnover of the whole market are considered natural monopolies. Therefore, the G8-theatres are natural monopolies. The question whether the Estonian state has done enough to compensate non-governmental theatres (called NonGov theatres) for the aggregation of resources to natural monopolies is one of the main focuses of this article. Here, two strategies are analysed: the activity of the Cultural Endowment of Estonia and the state's attempt to invest in building an alternative infrastructure for NonGov theatres.

Analogi og genealogi: protestantiske reformbuddhismer
Authors: Borup Jørn
Published: November 2018

ENGLISH ABSTRACT: Buddhism's history can be seen as a succession of reformisms. To focus the relevance of the concept, it is understood in this article as a concept measuring significant change within the religion itself and the surrounding community. With three examples from different contexts: ‘Protestant Buddhism' in the 19th century Sri Lanka, the Shin Buddhist reform movement in the Japanese Middle Ages, and Japanese diaspora Buddhism in Hawaii, the relevance of the term is investigated in relation to both genealogical and analogical reference to the Christian Protestant Reformation.

DANSK RESUME: Buddhismens historie kan ses som en lang række af reformismer. For at afgrænse begrebets relevans anvendes det i denne artikel om markante forandringstiltag med betydning for religionen selv og det omkringliggende samfund. Med tre eksempler fra forskellige kontekster: ‘Protestantisk buddhisme' i det 19. årh-. på Sri Lanka, shin-buddhistisk reformbevægelse i den japanske middelalder samt japansk diasporabuddhisme i Hawaii, undersøges begrebets relevans med genealogisk og analogisk reference til den kristne, protestantiske reformation.
