Hidrocarburos no convencionales en Argentina: exploraciones en lo profundo, transformaciones territoriales en superficie
Authors: Villalba María Sofía 
Published: July 2018

El desarrollo de hidrocarburos no convencionales en Estados Unidos ha generado una revolución en la industria petrolera en el ámbito mundial. Luego, otros países comienzan a explorar sus recursos. La cuenca Neuquina, Golfo San Jorge y, más recientemente, la Austral Magallanes en la Argentina observan desde la década de 2010 el desembarco de la actividad en sus territorios. Estos últimos se transforman económica, social y ambientalmente debido a las nuevas dinámicas que se instalan. Este trabajo busca analizar las principales transformaciones en las ciudades argentinas cercanas a la actividad hidrocarburífera no convencional. Para ello, se trabajó con fuentes primarias, a partir de entrevistas a informantes calificados y fuentes secundarias, principalmente material bibliográfico y de prensa. Se observa que la cuenca Neuquina, pionera en el desarrollo de la actividad, atraviesa las mayores transformaciones en su territorio, sobre todo en la ciudad de Añelo. En cambio, en la cuenca Golfo San Jorge y Austral Magallanes, las incipientes exploraciones en su territorio todavía no generan importantes cambios.
Exclusiones del espacio público de los habitantes de la calle en la ciudad de Buenos Aires
Authors: Rosa Paula Cecilia 
Published: July 2018

Este artículo pretende adentrarse en algunas de las posibles consecuencias que trae aparejada la implementación de políticas de tipo neoliberal en el espacio público, específicamente, en la Ciudad de Buenos Aires. El artículo se centra en la caracterización de la noción de ‘ciudad neoliberal’, para posteriormente adentrarse en las formas que asume la espacialidad neoliberal en dicha ciudad desde el caso de los habitantes de la calle, es decir, personas y familias que residen cotidianamente en el espacio público. Para desarrollar lo pretendido, el artículo versará en las formas por las cuales esta población se ve expulsada del espacio público por acciones indirectas y directas por parte de la administración de la ciudad. Asimismo, pretende dar a conocer una tendencia novedosa, en esta misma dirección, pero llevada a cabo por otro actor. Se hace referencia a la modalidad porla cual una parte de la ciudadanía asume, por sus propios medios, el reordenamiento del espacio urbano por medio de la instalación de barreras físicas para evitar u obstaculizar la presencia de esta población en los alrededores de sus propiedades. Este accionar permitiría observar la situación que atraviesan ciertos grupos sociales en una ciudad cada vez excluyente.
Pricing and Product Design for Vice Goods: A Strategic Analysis
Authors: Jain Sanjay , Li Krista J. 
Published: July 2018

The rising obesity epidemic is a worldwide concern for consumers, firms, and policy makers. One reason for the rise in obesity is consumers’ over-consumption of vice goods such as cookies, crackers, and soft drinks. Some authors have suggested that firms have incentives to make vice goods unhealthier and to encourage over-consumption. There are calls for regulations to ensure that firms make such products healthier by reducing harmful ingredients and provide nutritional information. Furthermore, public policy makers have begun to educate consumers to avoid over-consumption by using strategies such as pre-purchase planning. In this paper, we investigate how firms selling vice goods should respond to the growing concerns about obesity. We analyze how firms should adjust prices and product design to cater to consumers with self-control problems and obesity concerns. We use the literature on hyperbolic discounting to model consumers with self-control problems. In this framework, we examine how the unhealthiness of vice goods affects prices, firm’s profits, consumer surplus, and public health. In addition, we study how public policy efforts to encourage pre-purchase planning impact firm’s profits and consumers. Our results show that unlike standard goods, for vice goods a decrease in quality (i.e., increase in unhealthiness) and an increase in price can serve as a self-control device and increase demand. Therefore, firms sometimes can charge higher prices and make more profits by producing unhealthier products. Interestingly, producing unhealthier products can sometimes increase consumer surplus and improve public health. We also show that as the proportion of consumers who use pre-purchase planning increases, firms should respond by raising prices. In such situations, consumer surplus and public health improve but firm’s profits decline. These results have important implications for restaurants and firms that sell vice goods and for public policy makers who aim to combat obesity.

Carbon Tariffs: Effects in Settings with Technology Choice and Foreign Production Cost Advantage
Authors: Drake David F. 
Published: July 2018

Emissions regulation is a policy mechanism intended to address the threat of climate change. However, the stringency of emissions regulation varies across regions, raising concerns over carbon leakage—an outcome where stringent regulation in one region shifts production to regions with weaker regulation. It is believed that such leakage adversely increases global emissions. It is also believed that leakage can be eliminated by carbon tariffs, which are taxes imposed on imported goods so that they incur the same emissions cost that they would have if they had been produced in the regulated region. Results here contradict these beliefs. This paper demonstrates that carbon leakage can arise despite a carbon tariff but, when it does arise under a carbon tariff, it decreases emissions. Due in part to this clean leakage, results here indicate that a carbon tariff decreases global emissions. Domestic firm profits, on the other hand, can increase, decrease, or remain unchanged due to a carbon tariff, which suggests that carbon tariffs are not inherently protectionist as some argue. Rather, results here suggest that carbon tariffs improve the efficacy of emissions regulation, enabling it to reduce global emissions in many settings in which it would otherwise fail to do so.The online appendix is available at https://doi.org/10.1287/msom.2017.0674 .

Published: July 2018

Introduction Although links between meteorological conditions and primary spontaneous pneumothorax have been proposed, the reports are controversial. The aim of the study is to correlate between climatic changes and the development of this condition. Materials and methods A retrospective chart review included all patient presenting with primary spontaneous pneumothorax to King Fahd Hospital, Imam Abdulrahman Bin Faisal University, Alkhobar, Saudi Arabia, from 1 January 2005 to 31 December 2016. Meteorological data were collected from King Abdulaziz airbase station using an online source for the same time interval. The data were analysed to determine differences in weather conditions between days on which primary spontaneous pneumothorax occurred and those in which it did not. Logistic regression model was used to obtain predicted risks for the onset of primary spontaneous pneumothorax with respect to weather conditions. Result Two hundred and eighty-nine patients were found to have primary spontaneous pneumothorax in the 281 days included in the study. Among the meteorological parameters, significant differences were found in average temperature and atmospheric pressure difference between day of admission and two days before the admission, between days with primary spontaneous pneumothorax and days without. There was no significant difference in the other meteorological factors between days with primary spontaneous pneumothorax and days without. Conclusion Two hundred and eighty-nine patients were found to have primary spontaneous pneumothorax in the 281 days included in the study. Among the meteorological parameters, significant differences were found in average temperature and atmospheric pressure difference between day of admission and two days before the admission, between days with primary spontaneous pneumothorax and days without. There was no significant difference in the other meteorological factors between days with primary spontaneous pneumothorax and days without.
Perceived Subfecundity and Contraceptive Use Among Young Adult U.S. Women
Authors: Gemmill Alison 
Published: July 2018

CONTEXTWomen who view themselves as having difficulty becoming pregnant (i.e., being subfecund) may feel that they do not need to use contraceptives to prevent unintended pregnancy. However, subfecundity perceptions are not always medically accurate and may therefore confer a false sense of protection. The extent to which perceived fecundity is related to contraceptive use is not well understood.METHODSMultinomial logistic regression was used to investigate the relationship between perceived fecundity at age 25–30 and contraceptive use among 2,091 women from the National Longitudinal Survey of Youth 1997 cohort.RESULTSCompared with women who considered themselves very likely to become pregnant, those who thought that they were only somewhat likely and those who viewed themselves as not very likely to do so had significantly higher risks of not using contraceptives within the next year (risk ratios, 1.9 and 2.4, respectively). Results were similar in analyses controlling for either a medical diagnosis of infertility, a history of multiple miscarriages or stillbirths, or absence of pregnancy following at least six months of unprotected sex, suggesting that perceived subfecundity operates independently of experienced subfecundity.CONCLUSIONBecause few studies have investigated fecundity perceptions in their own right, more research is needed to understand how women evaluate their fecundity and to integrate these perceptions into broader frameworks describing women's perception of pregnancy risk. Such work may help identify potential levers to improve contraceptive use.

“Exquisite cadaver” according to Stanisław Lem and Andrzej Wajda
Authors: Ostrowska Elżbieta 
Published: July 2018

Abstract
The article examines Andrzej Wajda’s Roly Poly (Przekładaniec, 1968), a 35-minute film made for Polish public television, that is an expanded version of Stanisław Lem’s short grotesque play Do You Exist Mister Johns? (Czy Pan istnieje Panie Johns?) published in 1955. Roly Poly tells a story of a car race driver, Ryszard Fox. A victim of several car crashes, he gets so many transplants from other victims of these collisions, with his brother being a first donor, that eventually he becomes a mix of different organisms, including female and animal parts. Wajda presents the whole story in brief scenes and episodes using an aesthetic mix of black humor, grotesque, absurdism, surrealism, and pop art imagery. The author argues that with its narrative focus on transplant experiments and aesthetic concoction of different styles, Roly Poly becomes a cinematic variant of the surrealist parlor-game of exquisite cadaver, where an often accidental collection of words or images is assembled into a new entity. Furthermore, the article claims that the film presents a dystopian variant of Bakhtinian grotesque body and as such it opposes the concept of ideal, uniform, and homogenized communist/national body. Eventually, the body of transplants displays a transgressive potential of trespassing different divisions and hierarchies and as such it indirectly subverts the main premises of nationalistic politics led by Polish communist party in the late 1960s.

Abstract

Background
The aim was to study seven polymorphic markers of genes encoding proteins involved in the absorption, metabolism and pharmacokinetics of clopidogrel among patients with an acute coronary syndrome (ACS), who have undergone percutaneous coronary intervention (PCI).

Methods
Eighty-one ACS and PCI patients older than 18 years and treated with dual antiplatelet therapy were enrolled in the study. Platelet function testing and ABCB1, CYP2C19, CYP3A5 and CYP4F2 genotyping were performed. The predictive role of categorical variables, such as genotypes (carriers and non-carriers of polymorphism), on platelet reactivity (platelet reactivity units [PRU] platelet inhibition [PI]) was assessed by logistic regression (for categorical outcomes) and linear regression (for continuous outcomes) analysis. A p-value<0.05 was considered significant. The allele frequencies were estimated by gene counting, and Hardy-Weinberg equilibrium was tested using the chi-square test.

Results
Regarding clopidogrel response, 62 patients (76.5%) were clopidogrel responders and 19 were non-responders (23.5%). Mean PRU value and the percentage of platelet inhibition were 170.0±50.9 PRU and 28.6±19.9%, respectively. The effects of the CYP2C19*2 polymorphisms on PRU (166.0±50.8 vs. 190.7±48.2, p<0.038) and PI (30.6±20.0 vs. 18.1±16.3, p<0.013) were observed, and the rates of high platelet reactivity (HPR) were lower in CYP2C19*1/*1 than those in CYP2C19*1/*2+CYP2C19*2/*2 (16.2% vs. 53.8% p<0.0067). In comparison, no significant difference in PRU value and PI was observed at <5 days between the rest of polymorphisms (p>0.05). Based on the logistic regression analysis, CYP2C19*2 (OR: 4.365, CI: 1.25–17.67, p=0.022) was an independent predictor of HPR at <5 days, as was the stent diameter (OR: 0.219, CI: 0.002–0.229, p=0.049). The remaining polymorphisms had no influence.

Conclusions
The reactivity of the on-clopidogrel platelet in the early phase of ACS is influenced primarily by the CYP2C19 polymorphisms. We believe that the findings of the present study could supply additional evidence regarding the clinical appropriateness of the CYP2C19 genetic testing for designing suitable antiplatelet therapy in the early phase of ACS.
The energy intensity of the production of energy chips from dendromass stands on long-term uncultivated agricultural land
Authors: Oravec Milan , Slamka Marián 
Published: July 2018

Abstract
The aim of this work was to investigate the energy intensity of the fuel wood chips production on unused agricultural land. The unused agricultural land, overgrown with forest trees, also called white areas, is the result of the end of the traditional intensive management of agricultural land by the natural succession of forest stands and pioneers’ wood species on the borders of forest and non-forest land. These stands are advantageously localized due to previous method of the land utilization, accessible and therefore very interesting from the point of view of obtaining fuel dendromass. The logging and subsequent dendromass processing was carried out for the purpose of further land use as pasture land and also for the production of fuel wood chips and their subsequent sale to the end user. With the utilization of technology chain saw-forwarder-chipper, the energy intensity of each operation, expressed in terms of the amount of fuel consumed per unit of produced wood fuel, was determined. The share of energy consumed in the energy value of the harvested tree dendromass in the evaluated sites ranged from 0.43 to 0.62%, approximately 0.64 to 0.88% and the chipping 0.42 to 0.54%. The total amount of energy consumed after calculation the chipper transfers to an average distance of 180 km was within 1.46 to 2.11%. The average weight of the harvested trees caused the biggest impact on the energy intensity of the production process.
Surface chemical composition and roughness as factors affecting the wettability of thermo-mechanically modified oak (Quercus robur L.)
Authors: Laskowska Agnieszka , Sobczak Janusz W. 
Published: July 2018

Abstract
European oak wood (W) was thermo-mechanically modified (TM) via densifying at 100 and 150°C and the surface properties of the TMW were investigated. The contact angle (CA) of the wood with the reference liquids water and diiodomethane was determined using the sessile drop method. The surface free energy of the TMW on tangential sections within the first 60 s after applying a drop was analyzed. The roughness parameters Ra and Rz parallel (‖) and perpendicular (⊥) to the grain were investigated. The wettability analysis showed that densified wood had a higher CA and lower work of adhesion and surface free energy than non-densified wood. An X-ray photoelectron spectroscopy [XPS or electron spectroscopy for chemical analysis (ESCA)] analysis showed that the oxygen to carbon atoms ratio (O/C ratio) of densified wood surface was lower than that of non-densified wood. The carbon C1-C2 atoms ratio (C1/C2 ratio) increased with increasing TM temperature. The results were interpreted as being that extractives migrate to the surface and amorphous and glassy polymers, i.e. lignin and hemicelluloses, in wood are rearranged. Increasing densification temperature makes TMW surfaces more hydrophobic.
Physical plasma and leukocytes – immune or reactive?
Authors: Bekeschus Sander , Seebauer Christian , Wende Kristian , Schmidt Anke 
Published: July 2018

Abstract
Leukocytes are professionals in recognizing and removing pathogenic or unwanted material. They are present in virtually all tissues, and highly motile to enter or leave specific sites throughout the body. Less than a decade ago, physical plasmas entered the field of medicine to deliver their delicate mix of reactive species and other physical agents for mainly dermatological or oncological therapy. Plasma treatment thus affects leukocytes via direct or indirect means: immune cells are either present in tissues during treatment, or infiltrate or exfiltrate plasma-treated areas. The immune system is crucial for human health and resolution of many types of diseases. It is therefore vital to study the response of leukocytes after plasma treatment in vitro and in vivo. This review gathers together the major themes in the plasma treatment of innate and adaptive immune cells, and puts these into the context of wound healing and oncology, the two major topics in plasma medicine.
Tracing the “extinctness” of Tai Ahom: issues of language loss and death
Authors: Buragohain Dipima 
Published: July 2018

Abstract
The extinction of Tai Ahom, a language from the Tai-Kadai family that was once spoken in Assam, India, can be contributed to a number of socio-historical, linguistic and cultural factors including the development and strong influence of Assamese, a language from the Indo-Aryan family spoken in that region. In an effort to examine the dynamics that contributed to the loss of Tai Ahom, the current article focuses on a descriptive overview of issues including language shift, variation, and extinction in the case of Tai Ahom. It will also highlight the factors which contributed to its shift and gradual extinction and discuss current efforts to revive the language.
Prefacing opposition: Resources for adumbrating conflict talk in second language peer discussions
Authors: Aline David , Hosoda Yuri 
Published: July 2018

AbstractThis study provides an empirical analysis of conflict talk among second language learners, focusing on the opening aspects of conflict talk sequences, specifically the short sequences between an arguable and initial opposition. Data is based on 178 hours of small group discussions video-recorded in Japanese university English classes. Analysis revealed: (a) repetitions and why-type questions directly following an initial speaker’s claim were likely to adumbrate upcoming oppositions, (b) when a questioning repeat failed to elicit an account for the original speaker’s claim, the potential opposer explicitly pursued an account for the claim with a why-type question, (c) a major action these repeats and why-type questions performed was to call for speakers of potential arguables to provide sufficient accounts for their claims. The findings contribute to research on argumentative talk in classrooms by extending analysis beyond adjacent turns, by highlighting the resources of repetitions and why-type questions that speakers deploy to adumbrate oppositions, and by explicating the details of second language learner talk in peer discussions.
Surgical Procedures for Neuroendocrine Neoplasms of the Appendix: A Consensus Guideline Review
Authors: Vladova Paulina Tr. , Iliev Sergey D. , Popovska Savelina L. 
Published: July 2018

Summary
According to the consensus and the recommendations of the European Neuroendocrine Tumor Society (ENETS), the frequency of appendicular neuroendocrine tumors (NETs) is 0.15-0.6/100 000 a year. They are found a little more often in women aged between 40 and 50. Neuroendocrine neoplasms of the appendix are about 30 to 80% of all appendicular tumors. Their evolution is usually asymptomatic. They are diagnosed accidentally during a conventional or laparoscopic appendectomy. In the past, the surgical approach used to depend on the localization of the tumor. Currently, its localization is not a significant factor in the choice of a surgical approach. Our purpose wass to present the consensus guideline and the recommendations of ENETS 2017 for surgical procedures in neuroendocrine neoplasms of the appendix and analyze the difference in the survival rate in different surgical interventions. The literature overview includes studies on surgical treatment of neuroendocrine neoplasms of the appendix and takes into consideration the last consensus guideline of ENETS 2017 on the topic. ENETS recommends a simple appendectomy in well- differentiated appendix tumors smaller than 2 cm, regardless of their localization. Right hemicolectomy is performed for in tumors sized between 1 cm and 2 cm with positive resection lines, with deep mesoappendiceal invasion, high proliferation activity (G2) and vascular invasion. For tumors over larger than 2 cm – right hemicolectomy is recommended. Although current studies have pointed out no significant differences in survival rates between appendectomy for neuroendocrine neoplasms of the appendix and right hemicolectomy, ENETS 2017 suggests that the latest consensus guidelines should be followed.
