Research paper classification systems based on TF-IDF and LDA schemes
Authors: Kim Sang-Woon , Gil Joon-Min 
Published: August 2019

Abstract
With the increasing advance of computer and information technologies, numerous research papers have been published online as well as offline, and as new research fields have been continuingly created, users have a lot of trouble in finding and categorizing their interesting research papers. In order to overcome the limitations, this paper proposes a research paper classification system that can cluster research papers into the meaningful class in which papers are very likely to have similar subjects. The proposed system extracts representative keywords from the abstracts of each paper and topics by Latent Dirichlet allocation (LDA) scheme. Then, the K-means clustering algorithm is applied to classify the whole papers into research papers with similar subjects, based on the Term frequency-inverse document frequency (TF-IDF) values of each paper.
Super Fly: François Makandal’s Colonial Semiotics
Authors: Allewaert Monique 
Published: August 2019

Abstract
In this article I collate vernacular and elite academic stories about François Makandal, focusing particularly on his production of fetishes, which I (following his usage) call macandal. I show that the codes at work in macandal artifacts involve a materialism and semiotics that together constitute a critical methodology. I then use the methodology at work in macandal artifacts to read one key piece of the archive pertaining to Makandal: his judge and executioner Sébastien-Jacques Courtin’s Mémoire.
The Plantation Countermelodies of Dunbar and Du Bois: Writing Agropolitical Subjecthood in the Nadir
Authors: Child Benjamin 
Published: August 2019

Abstract
With attention to representations of the land and labor in the postslavery agricultural South of the nadir—a period when American apartheid was at its most violent—this essay uses Paul Laurence Dunbar’s plantation poems and W. E. B. Du Bois’s cotton novel, The Quest of the Silver Fleece (1911), to explore counternarratives of black subjecthood. Agriculture’s focus on productive collaborations with the nonhuman, on cycles of decay and rebirth, and on the potential for self-determination provides a generative vocabulary for conceptualizing nadir-era experiences of the human. Under this model, literature provides a venue wherein the legacies of the plantation might be imaginatively transposed from a Jim Crow necropolitics of violent constraint and dispossession into vectors of agropolitical possibility. To that end, the essay uses Dunbar and Du Bois to propose potentially radical processes of black subject formation wherein physical and imaginative instances of reclamation give rise to fresh mergers of epistemic and embodied selfhood.
Impact of CBCT on treatment decision related to surgical removal of impacted maxillary third molars: does CBCT change the surgical approach?
Authors: Hermann Louise , Wenzel Ann , Schropp Lars , Matzen Louise Hauge 
Published: August 2019

Objectives: To assess factors influencing treatment decision for maxillary third molars referred for cone beam CT (CBCT). Parameters influencing the decision to treat and to remove either the maxillary second molar or third molar were pursued. Methods: 111 impacted maxillary third molars, clinically examined including a panoramic image, in 86 patients (mean age 26 years, range 15–55) were referred for CBCT on suspicion of pathology/root resorption in the second molar, based on information in the panoramic image. The following parameters were assessed from the patient’s file, including the radiographic images: (1) third molar angulation; (2) initial treatment plan based on clinical examination and the panoramic image; (3) diagnoses based on information from CBCT; (4) treatment decision after additional CBCT information was available; (5) pre-/post-operative complications; (6) treatment of the maxillary second molar. Results: 70 cases (63.1%) underwent treatment, while 41 (36.9%) received no treatment. Change in treatment plan was registered in 65 cases (58.6%) after CBCT. In 12 cases (10.8%), treatment changed from removal of the third to removal of the second molar, while 25 (22.5%) were scheduled for removal in the initial treatment plan; but after CBCT, the decision was not to treat. If external root resorption involved the pulp of the second molar, there was an almost 17 times higher risk that this tooth was removed instead of the third molar (logistic regression analysis: odds ratio 16.8; p < 0.001). Conclusions: Findings in CBCT often changed the treatment plan. Severe external root resorption observed in CBCT was the main decisive factor for removing the second instead of the third molar.

Background: Identification of cell type subpopulations from complex cell mixtures using single-cell RNA-sequencing (scRNA-seq) data includes automated steps from normalization to cell clustering. However, assigning cell type labels to cell clusters is often conducted manually, resulting in limited documentation, low reproducibility and uncontrolled vocabularies. This is partially due to the scarcity of reference cell type signatures and because some methods support limited cell type signatures. Methods: In this study, we benchmarked five methods representing first-generation enrichment analysis (ORA), second-generation approaches (GSEA and GSVA), machine learning tools (CIBERSORT) and network-based neighbor voting (METANEIGHBOR), for the task of assigning cell type labels to cell clusters from scRNA-seq data. We used five scRNA-seq datasets: human liver, 11 Tabula Muris mouse tissues, two human peripheral blood mononuclear cell datasets, and mouse retinal neurons, for which reference cell type signatures were available. The datasets span Drop-seq, 10X Chromium and Seq-Well technologies and range in size from ~3,700 to ~68,000 cells. Results: Our results show that, in general, all five methods perform well in the task as evaluated by receiver operating characteristic curve analysis (average area under the curve (AUC) = 0.91, sd = 0.06), whereas precision-recall analyses show a wide variation depending on the method and dataset (average AUC = 0.53, sd = 0.24). We observed an influence of the number of genes in cell type signatures on performance, with smaller signatures leading more frequently to incorrect results. Conclusions: GSVA was the overall top performer and was more robust in cell type signature subsampling simulations, although different methods performed well using different datasets. METANEIGHBOR and GSVA were the fastest methods. CIBERSORT and METANEIGHBOR were more influenced than the other methods by analyses including only expected cell types. We provide an extensible framework that can be used to evaluate other methods and datasets at https://github.com/jdime/scRNAseq_cell_cluster_labeling.
DIREITO ROMANO E CONSTITUCIONALISMO GLOBAL
Authors: Osle Rafael Domingo 
Published: August 2019

O paralelo entre questões contemporâneas e história romana muitasvezes fascina e ilumina. Neste artigo, argumento que o direito romano, que foi uma das várias fontes de inspiração para os fundadores americanos, pode servir hoje como uma inspiração para o constitucionalismo global. Olhar para o direito romano ajuda a reduzir certos preconceitos derivados do atual privilégio do Estado soberano e do paradigma positivista como os únicos modelos genuínos e possíveis para o direito internacional. Esses preconceitos constituem um verdadeiro obstáculo ao desenvolvimento correto do constitucionalismo global. O constitucionalismo global se move inerentemente para além da soberania, do nacionalismo e do positivismo. O direito romano, que precedeu às noções de soberania, nacionalismoe positivismo, permite aos constitucionalistas eliminar do constitucionalismo global quaisquer elementos não fundacionais derivados de um paradigma altamente estatista. A lei romana também constitui um bom antídoto para qualquer tipo de constitucionalismo global extremo que busque estender a linguagem e os modos do constitucionalismo nacional sem filtrá-los e refiná-los suficientemente.
O REPRESSIVISMO PÓS-MODERNO BRASILEIRO DE ALTA INTENSIDADE. O DIREITO PENAL NA ENCRUZILHADA ENTRE O PENSAR CALCULADOR E A FUNDAMENTAÇÃO ÉTICO-POLÍTICA
Authors: Santos André Leonardo Copetti 
Published: August 2019

O presente artigo tem como objetivo principal desvelar a utilização deum modo de pensar calculador na formulação e na justificação das novas políticas penais – repressivismo penal pós-moderno de alta intensidade –, no qual o ser humano é mais um entre vários entes disponíveis para a ação do Estado, em detrimento de uma fundamentação filosófica – antropológica, baseada num pensar meditativo ético, espaço no qual o ser humano e seus principais bens – a vida e a liberdade – assumem posição central no processo discursivo de legitimação/limitação do poder penal estatal. A matriz teórica utilizada para a análise é a fenomenologia hermenêutica e o método, consequentemente, o fenomenológico.

O artigo aborda o direito humano à alimentação adequada previstona Constituição Federal e especifica como se constitui a “alimentaçãoadequada” à luz das dimensões ética e política que a permeiam. O objetivo geral é investigar o direito humano à alimentação adequada e às limitações de seu conceito legal, repensado a partir de considerações com origem na reflexão política e ética. A metodologia adotada envolve a pesquisa bibliográfica e documental, de caráter exploratório. Com base na discussão apresentada sobre o conceito de alimentação adequada, conclui-se que, para além de erradicar a fome, o direito à alimentação deve ser entendido de maneira mais ampla, de modo a pensar também no modo de produção dos alimentos e seus impactos tanto para os humanos quanto para os demais animais sencientes, passando necessariamente por uma reflexão do próprio consumidor, que deveter acesso à informação, a fim de realizar escolhas conscientes.
IMPRESSÕES SOBRE OS RUMOS DO PROCESSO PENAL BRASILEIRO: O QUE VEM POR AÍ?
Authors: Fayet Paulo , Castilhos Tiago Oliveira de 
Published: August 2019

O presente trabalho visa trazer uma reflexão [em forma de impressõese questionamentos dos autores] sobre o futuro do processo penal no Brasil, a partir das instâncias de acordos como formas de resolução das ações penais, principalmente com a chegada do instituto da colaboração premiada na Lei 12.850/2013, na medida em que a sua aplicação tem causado a desnaturalização do processo penal pátrio, justamente porque direitos estão sendo relativizados, e as regras e os prêmios têm trazido um grau pleno de incertezas e desacertos. Nesse sentido, o crescimento do número de causas penais resolvidas por meio de consensos abre espaço para a atuação dos órgãos da acusação pública, emdetrimento da atuação do Poder Judiciário, que passa a ser um fiscalizador dos acordos e dos prêmios sem a preocupação com a prova e com as questões de mérito da causa e, justamente em razão disso, reafirma a necessidade de se revisitar os sistemas inquisitório e acusatório, bem como as instâncias de um adversarial system, a fim de se estabelecer o que se pretende com as mudanças que já se fazem presentes no nosso ordenamento jurídico.
Secondary hypothyroidism in adults: diagnosis and treatment
Authors: Kienia Tatiana A. , Morgunova Tatiana B. , Fadeyev Valentin V. 
Published: August 2019

Secondary hypothyroidism is a rare disease. There is a number of questions and difficulties in diagnosis and management of this condition. There are two forms of secondary hypothyroidism: congenital (casuistic seldom) and acquired. The main causes of secondary hypothyroidism in adults are tumors of the hypothalamic-pituitary region and the state after surgical and radiation effects on this area. Hormonally active and inactive pituitary macroadenomas cause the development of acquired secondary hypothyroidism in more than 50% of cases. The development of secondary hypothyroidism is possible years after the radiotherapy of brain tumors. As well as in case of primary hypothyroidism, the clinical manifestations of secondary hypothyroidism are non-specific. Diagnosis and management of this pathology is often complicated by its combination with the deficiency of other tropic hormones. The diagnosis of secondary hypothyroidism is based on anamnestic data and laboratory tests - the simultaneous determination of the levels of fT4 and TSH. The level of fT4 today is also used as the main marker of the adequacy of the dose of L-T4 in the treatment of secondary hypothyroidism. The results of recent studies help us to optimize replacement therapy in secondary hypothyroidism. However, the use of additional biochemical markers to assess the adequacy of replacement therapy remains unexplored.
Embargoed exchanges: A critical analysis of emerging market dynamics in U.S. and Cuban academic exchange
Authors: Woodman Taylor C. 
Published: August 2019

Internationalization continues to remain a central focus within the U.S. university environment. The motives of internationalization are under question as neoliberal policies continue to limit sustained, long-term state funding for universities and undermine the academic mission of universities. Universities are leveraging internationalization practices, like study abroad programming, in response to the pressures of neoliberalism. In this study, qualitative case study methods were used to critically examine study abroad programming between the United States (US) and Cuba before, during, and after the Obama Administration’s announcement changing diplomatic relations between the U.S. and Cuba on December 17, 2014. The perspectives of 12 of the main actors in the field, including educational administrators and faculty from U.S. universities, Cuban universities, and study abroad program providers, were captured to provide a more comprehensive view of study abroad implementation in Cuba. The findings illustrate the influences of the neoliberal university environment in which study abroad programming is situated. These findings point to the prioritization of a market-based approach to study abroad programming, which amplifies inequities and power dynamics within north-south study abroad programs.

Los temas que emergen del análisis de contenido pueden agruparse en cuatro líneas principales de investigación: currículum, enseñanza y aprendizaje, trayectorias y experiencias de los estudiantes, profesión académica, y políticas de educación superior.
The construction of knowledge on “quality” in higher education: A study of universities’ websites in India
Authors: Srivastava Anamika 
Published: August 2019

In the context of India, the current paper studies the ways in which select public and private universities are representing themselves on their own website. In the process, the objective is to reveal what claims on “quality” in higher education (HE), are made by these universities; and how and why marketing power/knowledge influences these claims. Adhering to a critical realist discourse analysis approach, the paper not only describes the discourse on “quality” in HE on the selected universities’ websites but also makes an attempt to explain why marketing power/knowledge has come to have causal influence over the ways of knowing about “quality” in HE. Invoking, a moderate constructionist theory which is compatible with critical realism, it is accepted that knowledge on “quality” in HE is constructed discursively. However, these constructions are also shaped by non-discursive factors such as materiality, structural, institutional and physical embodied elements. The paper finds marketing power/knowledge is invested in the statements—both visual and textual, particularly on private universities’ websites. As mainstream marketing literature and practice recognize HE as a service and conceptualizes student/parent as a consumer, these universities’ websites have emerged as a site of playing out internet marketing strategies. There is an emphasis on tangibilization of the so-called HE service so that a prospective “student/parent-consumer” can see and find it cognitively easy to understand “quality” in HE. Consequently, one finds an emphasis on the discourses of “rankings”, “recognitions”, and “infrastructure” on these websites. In addition to this, one also finds influence of post-modern marketing and post-modern attitude towards truth on these statements. Marketers believe more in the appeal of these statements than in their authenticity. However, instead of invoking a relativist approach where only cultural factors are invoked to explain these influences, this paper hints towards materiality such as the ephemerality of the web, among others, as causal factors shaping these discourses.

Published: August 2019

The zone of Losari Coast is an icon of Makassar city, however increase activity of surrounding communities causes a decrease in the water quality. Meiofauna is an effective benthic organism used as an indicator of water quality. This study assessed the meiofauna abundance and physical-chemical parameters as water quality indicator in the Losari Coast, Makassar. The sampling method in this study was purposive sampling. The resuts showed that total meiofauna abundance identified was 66791 indv.m-2, composed of 12 phylum and 91 species or genera. Stations at the estuary of the Jeneberang and Tallo River are two sites with high level of abundance, this condition allows presence of organic contaminants triggers the high growth of meiofauna in these locations. Dissolved Oxygen is below its supposed level in waters. Acidity, phosphate and nitrate content at some of research stations exceed the threshold of their allowed presence in waters set by Indonesia government. Ostracoda, oligochaeta, polychaeta, tunicata and ciliophora are phylums with a high level of abundance, because the phylum has high adaptability to pollutant. Good water quality is indicated by a variety of biota living in the waters, the range of diversity and uniformity indices shows that meiofauna species are categorized highly diverse and evenly distributed. The dominance index shows that there is no species was dominant, except stations around Losari reclamation project. Temperature, current velocity, depth, brightness, salinity, pH, DO, nitrate-seawater, and phosphate-seawater correlate with meiofauna abundance. The results as a consideration for the management or monitoring of coastal environments.
