The Paradox of Literary Emotion: An Ancient Greek Perspective and Some Modern Implications
Authors: Munteanu Dana LaCourse
Published: January 2018

Fifth-century BCE Greek writers (e.g., Isocrates, Pseudo-Andocides) complain that the Athenians might have been more deeply moved by tragedies than by horrific contemporary events. My essay suggests that literary narratives could indeed produce this effect on us through several features. (1) The feeling of personal safety, threatened sometimes by our showing compassion to others (e.g. Euripides’ plays, Thucydides; modern refugee debates) remains intact when we engage in fiction. (2) The proximity to literary characters becomes enhanced by literary narratives (pro ommaton, focalization), in contrast to impersonal journalistic reports. (3) The universality ascribed to a literary piece (Aristotle’s Poetics) could contribute to our emotional immersion into the world of fiction to the detriment of the surrounding reality. While each section starts from ancient Greek authors, the essay will underline some similarities between the classical and the modern ways of engaging with literary narratives.

Religious Paradox and Aporia
Authors: Petropoulos Ioannis
Published: January 2018

Abordando o paradoxo religioso e metafísico – assunto, aliás, estranhamente bastante negligenciado –, este artigo investiga exemplos em fontes da literatura grega antiga e do início do Cristianismo, alguns bem conhecidos; outros menos. O paradoxo religioso é destacado em textos que vão de Hesíodo, Arquíloco, Heráclito e as Bacantes, de Eurípides, ao Evangelho de São João, São Paulo e Akathistos Hymnos, do século VI, em honra à Virgem Maria. Aporia, na esteira do paradoxo religioso, confirma a limitação humana e aponta para a transcendência do divino. O Cristianismo, a religião, por excelência, do paradoxo, reconhece a impossibilidade de oferecer “soluções” filosóficas para os paradoxos e aporias do dogma e recorre ao oximoro e paradoxo como a única forma adequada de expressão. O único recurso diante do estranho deslocamento da ordem e da lógica provocado pelo contato com o divino é a “ignorância”, pois, paradoxalmente, ἐν ἀγνοίᾳ γὰρ γίνεται γνωστὸς ὁ Θεός (“Deus se torna conhecido/conhecível por meio da ignorância”), como afirma São Dionísio Aeropagita.
Dilemas textuais na tradução crítica da República de Platão
Authors: Lopes Rodolfo Nunes
Published: January 2018

O presente texto diz respeito a alguns dilemas de tradução da República de Platão, os quais resultam directamente de problemas relativos ao estabelecimento do texto. O propósito destas páginas é, pois, fixar as coordenadas básicas que nos possibilitem circular pelo terrível labirinto da tradição textual deste diálogo, isto é, os princípios e critérios que permitam fundamentar e justificar as opções de tradução mais discutíveis, porquanto dependentes de problemas textuais. A proposta metodológica para enfrentar tais aporias será exemplificada com alguns casos paradigmáticos do Livro I. Tomarei como obras de referência os resultados do projecto editorial “Text edition of Plato’s eighth tetralogy”, iniciado em 1977 por Siem Slings, nomeadamente o trabalho de Gerard Boter sobre a tradição textual do diálogo (BOTER, 1989) e as notas de crítica textual publicadas por Slings entre 1998 e 2003, na revista Mnemosyne, postumamente coligidas e editadas em uma monografia enquanto suplemento dessa mesma revista (SLINGS, 2005).

Authors: Gupta Monika , Gupta Ravi
Published: January 2018

This is a rarest of rare case of surgical resection of giant retroperitoneal teratoma in a 15 yr old female child, causing displacement of left kidney to right by its huge volume (45X30X25cm= 33750cm3), making it appear like acquired crossed confused renal ectopia. Teratomas can occur anywhere in abdomen. Ovary being most common site followed by retroperitoneum. The most common age group is <1yr of age but they can present in any age. There are various case reports describing giant teratomas of various sizes in children and adults. Largest reported size is of 35x35cm size in a 33 yr old female. The case author has operated is rare case ever reported of ‘most voluminous retroperitoneal teratoma in 15 yr old female’ with displacement of all intra-abdominal structures by its volume. Tumor was 45x30x25cm with 12kg weight. When presented patient had complaints of vague discomfort and extreme abdominal distension progressive over last 1 yr. Patient underwent surgery -Excision of tumor, which needed dissection from superior mesentric artery and vein, splenic vein, pancreas, retroperitoneum, splenic vein, diaphragm and left kidney. Left kidney was rotated to right side, causing it to appear like ‘acquired crossed confused renal ectopia’ The left kidney was safely replaced to its original position in left renal fossa. The histopatholgy of tumor was of mature teratoma with no evidence of malignancy. Patient remained symptom free and recurrence free during 5 yrs follow up. Mature cystic teratomas are benign in nature they can attain enormous size in abdomen and can displace any intrabdominal structure. Surgeons should be aware that these big tumors can be resected with preservation of displaced structures in abdomen. Careful surgery is essential for preservation of abdominal organs and to ensure quality of life of patient.

No patient had poor result (score less than 65). 19 patients (95%) returned to their pre-injury employment at 1 year.

Conclusions: Open reduction and internal fixation with volar locking plate is reliable and excellent methods of management of intra-articular fracture of distal end of radius especially shear type of injury (AO type B2 and B3) in adults. 
Addressing Multicultural Conflicts: An emphasis on procedural fairness
Authors: Brems Eva
Published: January 2018

This paper examines the procedural fairness dimensions of approaches to multicultural conflicts. The paper explains the findings of procedural fairness research in social psychology and explores its relevance for the field of (human rights) law, and for the setting of multicultural conflicts. It argues that there are strong reasons in favour of seeking to optimize procedural fairness —with its criteria of participation, trustworthiness, neutrality and respect— across all types of procedures that address multicultural conflicts. The paper illustrates these criteria through three reallife cases, concerning multicultural conflicts that occurred in Belgium in recent years. The paper furthermore explores the relationship between the normative implications that may be drawn from empirical procedural fairness research and existing procedural fairness norms in human rights law.Received: 21 June 2017Accepted: 10 October 2017Published online: 31 January 2018
Derechos territoriales indígenas, pluralismo jurídico y alternativas al desarrollo: notas sobre una relación indisoluble
Authors: Álvarez Yesica
Published: January 2018

Los derechos territoriales indígenas son analizados en el presente trabajo como una reivindicación indisolublemente unida a la defensa de un modo de vida opuesto al modelo de desarrollo convencional y al mantenimiento del Derecho, autoridades e instituciones indígenas. Partiendo de la oposición de muchos pueblos indígenas y tribales a planes y proyectos de desarrollo e inversión, se plantea la necesidad de analizar conjuntamente las reivindicaciones de los pueblos indígenas por sus derechos sobre sus tierras, territorios y recursos naturales a la luz de las críticas al desarrollo convencional enunciadas desde la perspectiva postdesarrollista y de los estudios sobre el pluralismo jurídico que cuestiona el monismo asociado al Estado-nación moderno. Para ello, se pondrá bajo la óptica de lo que hemos denominado «pluralismo jurídico en clave postdesarrollista» el proceso de «emergencia indígena» y los derechos territoriales indígenas reconocidos por el Sistema Internacional de Naciones Unidas y por el Sistema Interamericano de Derechos Humanos.Recibido: 28 junio 2017Aceptado: 18 octubre 2017Publicación en línea: 31 enero 2018
Selected GARCH‑type Models in the Metals Market – Backtesting of Value‑at‑Risk
Authors: Krężołek Dominik
Published: January 2018

Risk analysis in the financial market requires the correct evaluation of volatility in terms of both prices and asset returns. Disturbances in quality of information, the economic and political situation and investment speculations cause incredible difficulties in accurate forecasting. From the investor’s point of view, the key issue is to minimise the risk of huge losses. This article presents the results of using some selected GARCH‑type models, ARMA‑GARCH and ARMA‑APARCH, in evaluating volatility of asset returns in the metals market. To assess the level of risk, the Value‑at‑Risk measure is used. The comparison between real and estimated losses (in terms of VaR) is made using the backtesting procedure.

Published: January 2018

In so far, articles portraying Balinese Hindu who settles in far away from Bali Island are less widely published. In recent development of Hinduism in Indonesia, Hindus community shows a dynamic process and tries to adapt culture of majority people in some areas. This article tries to explore the dynamics of Balinese Hindu community which is assumed a diasporic Balinese who settle in a small town Cimahi, West Java Province of Indonesia. This article shows that the Balinese Hindu in Cimahi can perform flexibility of Hindu doctrine as well as Hindu ritual which mean they do not totally follow the core of its culture, that is Balinese culture. Yet, they maintain banjar system and adhere Parisada Hindu Dharma of Indonesia’ decrees instead of joining India Hinduism of sampradaya. This article is stemmed from a qualitative research toward Hindu community in Cimahi of West Java province whereby they maintain their religious tradition (including pancayadnya) embedded with an old temple namely the Great Wira Loka Natha temple. This temple is regarded by themselves as the oldest Balinese temple in West Java which was built in 1978. To collect the data, the research uses observation, in-depth interview, focus group discussion as well as literature study.

Authors: Elizabeth Misbah Zulfa
Published: January 2018

Although it was stated that nowadays is “the third wave”, the time for minority, included women, for taking part in so many public activities, it did not mean that women can do as they really want to do to express their capacities as well as capabilities in their life cyrcle. Applying literature study it was revealed that although women can choose their activities, domestic or public, but the fact showed that there are so much cultural burden that women may encounter in the both sphere of their life. Women impoverishment is the term that seemed appropriate to the condition that are the women facing in choosing their life, both in domestic and public sphere because of the domination of globalization. This article showed that factually women took part in most of public sectors but generally women posited in lower level of access, participation, and respect. By reflective method, even religion treated women as other social processes. There are some biases view on women disseminated in religious spreading that effected in the sustainability of the gender inequality in society context.

Authors: Rosário Frederico , Santos Maria Inês , Angus Kathryn , Pas Leo , Fitzgerald Niamh
Published: January 2018

Introduction: Alcohol is a leading risk factor contributing to the global burden of disease. National and international agencies recommend evidence-based screening and brief interventions in primary care settings in order to reduce alcohol consumption. However, the majority of primary care professionals do not routinely deliver such interventions.Objective: To identify factors influencing general practitioners/family physicians’ and primary care nurses’ routine delivery of alcohol screening and brief intervention in adults.Material and Methods: A systematic literature search will be carried out in the following electronic databases: Medline, CINAHL, CENTRAL, and PsycINFO. Two authors will independently abstract data and assess study quality using the NIH National Heart, Lung, and Blood Institute quality assessment tools for quantitative studies, and the CASP checklist for qualitative studies. A narrative synthesis of the findings will be provided, structured around the barriers and facilitators identified. Identified barriers and facilitators will be further analysed using the Behavioural Change Wheel/Theoretical Domains Framework.Discussion: This review will describe the barriers to, and facilitators for, the implementation of alcohol screening and brief interventions by general practitioners/family physicians and nurses at primary care practices. By mapping the barriers and facilitators to the domains of the Behavioural Change Wheel/Theoretical Domains Framework, this review will also provide implementation researchers with a useful tool for selecting promising practitioner-oriented behavioural interventions for improving alcohol screening and brief intervention delivery in primary care.Conclusion: This review will provide important information for implementing alcohol screening and brief intervention in primary health care.Systematic Review Registration: PROSPERO CRD42016052681
Déjà vu no neoconstitucionalismo?

Este trabalho objetiva analisar se o neoconstitucionalismo configura uma nova vertente ou se suas características já se faziam presentes com o advento do constitucionalismo. Será utilizada pesquisa bibliográfica com método de abordagem hipotético-dedutivo e com métodos de procedimentos histórico, comparativo e interpretativo. A técnica de pesquisa utilizada será a documentação indireta. A organização do artigo foi feita através de perguntas cuja temática proporciona ao leitor conhecimento teórico para que formule sua própria conclusão, independente da esboçada no presente trabalho. Dessa forma, crer que o neoconstitucionalismo é mesmo novo depende da pré-compreensão que se tem, com suas limitações inerentes. Ao admitir que os princípios já faziam parte da Lei Maior, ao aceitar a mutação das normas constitucionais e ao compreender que a interpretação não tem ponto de chegada por ser um processo em desenvolvimento e, principalmente, que a Constituição é uma obra inconclusa, não se torna possível assumir tal crença.

The role of systemic antibiotics in root canal treatment (RCT) always remained controversial. To exactly identify the state of affairs, regarding whether or not the usage of systemic antibiotics in RCT, the current meta analysis was carried out. To identify the frequency of discouraging or preferring the use of systemic antibiotics in RCT. Secondly to identify the efficacy of various antibiotics in post RCT infections. Department of Operative Dentistry, Rawal Dental College Islamabad and Pathology Department of Al Nafees Medical College & Hospital, Isra University Islamabad Campus, Pakistan. Total 41 published studies in 03 and a half decades were included in the study i.e 1981 – 2017. Various authentic electronic sources were used to gather adequate and authentic data by simple random sampling technique. 66.6%(n=08) studies from 1987 till 2011, were not in favour of using systemic antibiotics as a part of RCT. While 33.3% (n=04) preferred using systemic antibiotics for RCT. Regarding the local antibiotic preference, 33.3% (n=04) studies were in favour of using a combination of triple antibiotic paste comprising of metronidazole, minocycline and ciprofloxacin. There is no role of systemic/local antibiotics in endodontic management. However, the use of antibiotics is only recommended if deemed necessary by viewing the premorbid of patient.

Content Analysis of Canadian Academic Library Gift and Donation Webpages
Authors: Empey Heather
Published: January 2018

Gifts and donations form an integral part of an academic library’s existence, whether monetary or physical items. While monetary gifts are greatly valued, gift-in-kind donations of physical items can also contribute rare or unique items to collections. However, gift-in-kind donations also bring many challenges, as processing and evaluating physical materials can be time-consuming and labour-intensive; moreover, these materials may occupy significant amounts of space and ultimately may or may not add value to the library collection. Providing clear, publicly available gift and donation information can mitigate some of these challenges and help to set expectations for donors by giving a clear overview of the evaluation process and letting them know which types of material are of interest. The author reviewed donation-related webpages of twenty-one Canadian academic libraries to determine commonalities regarding library donation webpages. This analysis can provide practical assistance to librarians who are creating or revising gift-in-kind policies and procedures in Canadian academic libraries.

Les dons monétaires ou matériels font partie intégrante de l'existence d'une bibliothèque universitaire. Bien que les dons monétaires soient très appréciés, les dons matériels peuvent aussi contribuer à des collections d'articles rares ou uniques. Toutefois, les dons en nature posent également de nombreux défis, car le traitement et l'évaluation des documents physiques peuvent prendre beaucoup de temps et exiger beaucoup de travail; en outre, ces documents peuvent prendre beaucoup d'espace et, en bout de ligne, ils peuvent ou non ajouter de la valeur à la collection de la bibliothèque. Il importe alors de fournir au public des informations claires sur les dons afin de palier certains de ces défis et d'établir des attentes pour les donateurs en leur présentant un survol clair du processus d'évaluation et en leur laissant savoir quels types de matériel sont d'intérêt. L'auteure a recensé les pages Web consacrées aux dons de vingt-et-une bibliothèques universitaires canadiennes afin d'y déceler les points communs. Cette analyse peut fournir une aide pratique aux bibliothécaires qui créent ou qui révisent des politiques et des procédures pour les dons en nature dans les bibliothèques universitaires canadiennes.
Q&A: An Interview With Halliburton CEO Jeff Miller
Authors: Donnelly John

Q&A

Your North America business is doing well. Will that continue to be your focus in the short term?

We are really excited about our business in North America. We have always had significant investment in North America and as we look at the immediate future, it will be the busiest market. It is extremely impactful on many different stages.

Do you see a slowdown in the unconventional business in North America, or do you think it is still on the way up?

I think that North America is going to be very resilient in a $50–55/bbl world. There is a lot of demand for North America resources and I think the speed to market is really relevant and important, particularly as demand increases. Unconventionals can fill that demand most quickly because of the timing more than anything else, which is a real advantage relative to mature fields and particularly deep water.

There is a lot of demand for what we do and I expect that we will be very busy in 2018. The sense I get from the customers is that the outlook is good at current commodity prices. We continue to reduce costs and make more barrels. And that’s how Halliburton spends most of its time—determining how to deliver the lowest cost per BOE.

Any fear that equipment shortages or labor shortages could slow activity?

I don’t think they will. The market is undersupplied today. We estimate that the market is about a million-and-a-half horsepower undersupplied for pumping equipment and I think the other services are also quite tight. Layer onto that the challenges with people and the shortages actually generate a flight to quality. One of the reasons I am confident about our business is that we have been disciplined about maintenance of our equipment and hiring people well ahead of time. That comes at a cost but the fact is there is no substitute for service quality. No substitute.

Outside of North America, where are the highest priorities for Halliburton?

We have outperformed the market through the downturn internationally in seven of the past eight quarters. The Middle East is extremely important to us. One of the things I am most pleased with is the ability of Halliburton to focus intently on North America, but at the same time steadily grow our international footprint. The fact is, we are present in every important market around the world today. That is something we could not have said 10 years ago and maybe even 5 years ago.
Technology Focus: Well Testing (February 2018)
Authors: Lee Heejae
Published: January 2018

Technology Focus

Well testing and surveillance have always been, and continue to be, the foundations of reservoir management. Fundamental data, such as pressure, rate, and temperature, and fluid samples are collected during a well test and used to investigate the subsurface. With advancements in modern technology such as smart wells, distributed pressure/temperature, real-time measurements, and extended-reach drilling, we are facing conditions with increasing complexity and unprecedented amounts of data.

In 2017, several key partnership announcements with major information-technology companies were noticed. The oil and gas industry is going through a digital transformation reinforced by data science; terms such as data cloud/lake, machine learning, Internet of Things, high-performance computing, automation, and model management are the new buzzwords. When analytics are applied correctly, they will provide valuable insights, especially in cases such as unconventional reservoirs with significant numbers of wells. In order to make the transformation a success, many of the industry’s leading experts agree that quality as well as quantity of data should be important.

Experience teaches us that the subsurface is always more complex than we expect, feedback is not instantaneous, and issues are difficult to mitigate in the reservoir scale. Hence, essential and information-rich data such as exploration/production-well tests, proper fluid samples, and sufficient/periodic surveillance should still be used effectively as indicators to peel off layers of uncertainty in the complex subsurface. Thus, we conclude that reservoir-engineering fundamentals must still be applied and data should still be quality checked, especially when collecting and applying analytics from a massive amount of information. The age-old “garbage in, garbage out” mantra will continue to apply in the upcoming era of data science.

The papers selected for this issue cover advances and opportunities in well testing. They also apply reservoir fundamentals as well as sound engineering judgment, using quantity but also quality data sets from conventional and unconventional assets.

Strictly local one-dimensional topological quantum error correction with symmetry-constrained cellular automata
Authors: Lang Nicolai , Büchler Hans  Peter
Published: January 2018

Active quantum error correction on topological codes is one of the
most promising routes to long-term qubit storage. In view of future
applications, the scalability of the used decoding algorithms in
physical implementations is crucial. In this work, we focus on the
one-dimensional Majorana chain and construct a strictly local decoder
based on a self-dual cellular automaton. We study numerically and
analytically its performance and exploit these results to contrive a
scalable decoder with exponentially growing decoherence times in the
presence of noise. Our results pave the way for scalable and modular
designs of actively corrected one-dimensional topological quantum
memories.
Macroeconomic announcements and stock returns in US portfolios formed on operating profitability and investment
Authors: Alexiou Constantinos , Vogiazas Sofoklis , Taqvi Abid
Published: January 2018

The authors explore the reaction of US stock portfolio returns to macroeconomic announcements spanning the period from April 1998 to May 2017. Using daily returns of 25 portfolios formed on operating profitability and investment, the authors investigate the extent to which potential asymmetries permeate the stock portfolios following macroeconomic announcements. The three methodological approaches utilized in this study suggest that the ISM non-manufacturing index, employees on non-farm payrolls, retail sales, personal consumption expenditure and initial jobless claims have a significant impact on portfolio returns. Also, portfolios consisting of companies with higher operating profitability and investment level are found to be less responsive to announcements. As the particular area has received little currency over the years, this contribution is of great significance, because it provides insights into the reaction of returns in value-weighted portfolios to announcements on certain macro-indicators. At the same time, the study informs portfolio managers of the implications of macroeconomic news, which drive economic expectations and can reverberate through the expected returns in US stock portfolios.
Global parameters of social economy clustering
Authors: Stukalo Nataliia , Simakhova Anastasiia
Published: January 2018

The study of various aspects of social economy is stipulated by the fact that the focus of any economic system is the human being as the main object and the result of economic activity. The purpose of this paper is to cluster of social economies of the countries throughout the world with distinguishing the models of social economy for transition economies under globalization conditions. The results of research represent four clusters of social economy that prove validity of classification of 4 classic models of social economy: liberal, Scandinavian, corporatist, and Mediterranean. While the most developed countries have effective models of social economy, there is still no clear concept of social development for transition economies. This paper deals with social economy clustering of different countries with the view to determinate the place of transition economies in social metrics of global economy. Our study is limited to the number of countries – 40 countries of the world, mainly European, and timeframes – 2015 and 2016. The obtained results could be taken into account by governments when developing and implementing new social policy for transition economies considering the experience of countries with classical social models. The authors propose the main practical tools for transition social model. It is proposed to distinguish one more model of social economy – the transition model, typical for transition economies that implement social reforms and has some common features.
Skin transplantation in mice as an animal model for functional analysis of T regulatory cells.
Authors: ŻYŁKO ANNA , WARDOWSKA ANNA , TRZONKOWSKI PIOTR
Published: January 2018

The role of T regulatory cells (Tregs) in transplantology has been widely studied over the years. The mouse model of skin transplantation is used as a quick and easy way to monitor the immune response of Tregs, vital for creation and maintenance of homeostasis and immunological tolerance. This model is extremely useful in the assessment of allograft rejection and immune tolerance induction dependent on Tregs. The procedure of skin transplantation is widely used not only in transplantology, but also in studies on the effectiveness of various immunosuppressive compounds and studies on autoimmune diseases, including diabetes, multiple sclerosis and albinism. The improved protocol of mouse tail skin grafting is easy to master, and its wide application gives many opportunities for new solutions in biomedical research..
