Small and Smart: Why and How Smart City Solutions Can and Should be Adapted to the Unique Needs of Smaller Cities
Authors: Lam Debra , Givens John Wagner
Published: April 2018

Research and development on smart cities has been growing rapidly. Smart cities promise a new era of living efficiently, sustainably, and safely. The tools and technologies deployed aim to drive better public decision-making on everything from where we live to how we work. While the world is rapidly urbanizing, a substantial percentage of the population still lives in smaller and rural communities. Smart city solutions as they are defined here are process driven and not constrained by population or geographic metrics; they are the application of technology and data to improve the quality of life. Smaller communities can also be smart, and excluding or ignoring them widens inequality, limits use cases, and restrains innovation. Using South Bend, Indiana as an example, the authors examine the power and potential of smaller smart cities. They then transfer this thinking to Georgia and Georgia Tech’s initiative working with local governments across the state on smart community development. This article is one of the first of its kinds in examining smaller smart communities as models for smart living.
Introduction
Authors: Klaus Ian , Acuto Michele
Published: April 2018

A number of economists, historians, and political scientists have begun to examine what happens when globalization unravels. From an urban point of view, this question seems at odds with current trends: the reaction to globalization has come about at a time where, paradoxically, international discussions around the future of cities and their contribution to global sustainability have galvanized international cooperation amongst multilateral, regional, private and local actors. Does this mean that we should rethink these trends? Taking this cue, we ask what happens when globalization unravels in a more focused urban way: what happens to the global city when the economic and political relationships behind the postwar international order, and in particular the post-1970 version of that order, begin to fray or come completely undone? What happens then if the globalization of the global city unravels when its core material and infrastructural conditions are now necessarily globalized? This special issue of New Global Studies seeks to open an interdisciplinary and critical debate about the real possibilities of de-globalization and the challenges, and the dangers, of an unraveling globalization in a more and more urbanized world.
An efficient analytic approach for solving Hiemenz flow through a porous medium of a non-Newtonian Rivlin-Ericksen fluid with heat transfer
Authors: Parand Kourosh , Lotfi Yasaman , Rad Jamal Amani
Published: April 2018

In the present work, the problem of Hiemenz flow through a porous medium of a incompressible non-Newtonian Rivlin-Ericksen fluid with heat transfer is presented and newly developed analytic method, namely the homotopy analysis method (HAM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. This flow impinges normal to a plane wall with heat transfer. It has been attempted to show capabilities and wide-range applications of the homotopy analysis method in comparison with the numerical method in solving this problem. Also the convergence of the obtained HAM solution is discussed explicitly. Our reports consist of the effect of the porosity of the medium and the characteristics of the Non-Newtonian fluid on both the flow and heat.
Rapid expansion of the Asian clam Corbicula fluminea (O. F. Müller, 1774): a new alien species in the mollusk community of the Vistula
Authors: Bonk Maciej , Zając Katarzyna , Lipińska Anna M.
Published: April 2018

A new large population of the Asian clam Corbicula fluminea (O. F. Müller, 1774) was found within a reach (ca 210 km long) of one of the largest European rivers, the Vistula. The largest population and the largest individuals were found at the outlet of a channel collecting heated water from the cooling process at the Połaniec power station and adjacent parts of the river. In the northern part of the study area, bivalves occurred at the channel margins, in groyne fields, and in the shallows of sand banks or sandbars. The clams were less numerous in places where the river was regulated with straightened banks and stone ripraps. Twenty-five other taxa of mollusks were found altogether at the sampling stations where Corbicula was observed, including other non-indigenous mollusk species.
Underwater noise emitted during small-scale air entrainment events
Authors: Szuszkiewicz Justyna , Klusek Zygmunt
Published: April 2018

The breaking wave phenomenon significantly takes part in the mechanisms of mass, heat and gas exchange at the air-water boundary and depends on the wind velocity. Some of the energy dissipated during this process is converted into underwater sound emitted by oscillating gas bubbles and bubble plumes. However, the underwater noise accompanying the lowest wind speed conditions has received only little attention. This report describes a study aimed at advancing the knowledge of underwater noise emission from air bubbles injected during small-scale breaking events occurring on the water surface. Results of model experiments performed in a small tank are presented. The object of the research is the relationship between the generated noise and the dissipated potential energy of water poured into a tank filled with water of varying physical water properties. Additionally, the impact of various water properties such as salinity, surface tension or microscale gas bubbles was examined. The experiment revealed that noise spectra are affected by different water properties and most likely reflect the varying efficiency of bubble formation and bubble size spectra.
Managing the Electronic Resources Lifecycle with Kanban
Authors: McLean Jaclyn , Canham Robin
Published: April 2018

This paper discusses the implementation of Kanban as the framework for managing electronic resources workflows by presenting case studies from the University of Saskatchewan Library and at the Saskatchewan Polytechnic Library in Saskatchewan, Canada. Librarians at both institutions independently chose to adopt Kanban to manage electronic resources work, applying the essential Kanban framework of lists titled to do, in progress, and done. Examining the similarities and differences in each librarian’s experience and discussing two different software programs used, we have included descriptions of our implementation, in-depth information about the origins of Kanban, and its more recent applications to technical work. We found numerous benefits-including reduced email communication and improved due date tracking-to our implementation of Kanban and no significant drawbacks. Interest in applications of Kanban in libraries is on the rise, and we found there were significant benefits of using Kanban for electronic resources teams when used in conjunction with other tools (e.g., spreadsheets, email, ERMS).
Enzymatic preparation of functional polysaccharide hydrogels by phosphorylase catalysis
Authors: Kadokawa Jun-ichi
Published: April 2018

This article reviews enzymatic preparation of functional polysaccharide hydrogels by means of phosphorylase-catalyzed enzymatic polymerization. A first topic of this review deals with the synthesis of amylose-grafted polymeric materials and their formation of hydrogels, composed of abundant natural polymeric main-chains, such as chitosan, cellulose, xantham gum, carboxymethyl cellulose, and poly(γ-glutamic acid). Such synthesis was achieved by combining the phosphorylase-catalyzed enzymatic polymerization forming amylose with the appropriate chemical reaction (chemoenzymatic method). An amylose-grafted chitin nanofiber hyrogel was also prepared by the chemoenzymatic approach. As a second topic, the preparation of glycogen hydrogels by the phosphorylase-catalyzed enzymatic reactions was described. When the phosphorylase-catalyzed enzymatic polymerization from glycogen as a polymeric primer was carried out, followed by standing the reaction mixture at room temperature, a hydrogel was obtained. pH-Responsive amphoteric glycogen hydrogels were also fabricated by means of the successive phosphorylase-catalyzed enzymatic reactions.
Green chemistry in mineral processing: chemical and physical methods to enhance the leaching of silver and the efficiency in cyanide consumption
Authors: Alarcón Alejandro , Segura Carlos , Gamarra Carlos , Rodriguez-Reyes Juan Carlos F.
Published: April 2018

The leaching of valuable metals from mineral ores is the basis of several extractive economies around the world, but the strategies employed often need to rely on dangerous compounds such as cyanides. Due to the complex nature of most ores, leaching processes are slow and have a low efficiency in noble metal extraction, which is usually improved by fine-milling the mineral. In this manuscript, we consider this strategy, demonstrating that it may increase the amount of silver leaching, but at the expense of a higher consumption of cyanide, which renders the process inefficient (only 2% of consumed cyanide is employed to complex silver). The increase in the yield of the desired product without the smarter use of dangerous compounds is shown as a paradigm of the need to insert green chemistry principles in industrial processes. We further present the result of two potential strategies for greener mineral processing: the use of ultrasound to eliminate passivating layers formed during the leaching process and the use of chemical pretreatments to eliminate possible sources of passivation. These strategies can increase the amount of silver extraction and simultaneously increase the efficiency in cyanide consumption. The convenience of these pretreatments in the framework of the green chemistry principles, as well as the challenges towards their implementation at industrial scale, is discussed.
A Metaliterary Approach to Ursicinus’ Outburst (Amm. Marc. 20.2.4)
Authors: Hanaghan Michael
Published: April 2018

In 359 CE Constantius II appointed investigators into the fall of Amida, who confronted Ursicinus, a commander in the East, about the disaster. He refused to play along, answering them instead with a stirring outburst that predicted the imminent failure of the emperor unless he freed himself from his meddling eunuchs and his obsession with Amida. This assessment may be read as a metaliterary comment that reflects both forwards and backwards; up until that point, Constantius has been pulled along by the judgments of others, including his eunuchs, again and again. In contrast, Julian is presented as a bold and independent judge of people and events who actively carries out his responsibilities. As the narrative unfolds, Ursicinus’ prediction is borne out: Constantius never gets over the fall of Amida nor the influence of his eunuchs and eventually fails. The eclipse excursus that follows enhances the prophetic force of Ursicinus’ words as Julian is proclaimed Augustus and Constantius nervously dithers over what he should do. Ursicinus’ outburst is crucial to his narrative role and the important intratextual links that are drawn between the main individuals in Ammianus’ narrative of Constantius’ fall and Julian’s rise, including Gallus, Silvanus, Julian, Constantius, Eusebius, and Ammianus himself.
Electrochemical treatment of metal inserts for subsequent assembly injection molding of tight electronic systems
Authors: Kleffel Tobias , Drummer Dietmar
Published: April 2018

One method to produce electronic systems with high resilience is the encapsulation of metal inserts, for example, lead frames, using assembly injection molding. Such parts are exposed to different mediums, such as water and oil, which can infiltrate and damage the electronic system, especially in automotive applications. Hence, one challenge is to ensure the tightness. The research covered in this paper focuses on the assembly injection molding of tight electronic systems using microstructured metal inserts, manufactured by a two-stage electrochemical treatment. The effects of the electrochemical treatment on the tightness and the bond between metal and polymer of the electronic system are investigated. Furthermore, the influence of the electrochemical treatment on the surface and geometry of the metal insert is evaluated.
Sense of local identity, attitudes toward dialects and language teaching: The Hungarian minority in Serbia
Authors: Kovacs Rac Eleonora , Halupka-Rešetar Sabina
Published: April 2018

A large body of academic literature (e.g. Fishman 1977, 1999; Giles and Johnson 1981; Romaine 2000, among others) claims that language is one of the most significant markers of ethnic identification and that it plays a crucial role not only in the external perception of an ethnic group by outsiders but also in the selfidentification of an ethnic group. In a minority environment, sense of ethnic identity and language retention are connected very tightly, which is why it is of extreme importance to study attitudes towards the dialects of a language and value judgments about them. The paper presents the results of a research into attitudes toward dialects, conducted with approximately three hundred 5th and 8th grade pupils (age 12 and 15, respectively) attending school in Hungarian in two regions of Vojvodina, Serbia. It explores the subjects’ local features of identity, given that the research was conducted in eight different localities. The results of the research serve as a sound basis for developing use-centered, functional-situational mother tongue education of Hungarian minority pupils living in Serbia, since the current curriculum completely disregards the language varieties of many Hungarian minority pupils brought up and living in rural areas, who acquire and use the dialect spoken in the family.
An analysis of attitude in chinese courtroom discourse
Authors: Shi Guang
Published: April 2018

Attitude is an important resource for courtroom discourse to perform interpersonal functions. This paper analyzes the attitude expressions in the audio recording transcripts of eight trials and finds that: judgement is the most important way for courtroom participants to express attitude, followed by appreciation, while affect is the least frequently used. In the four criminal trials, the defendants express attitude most frequently and most negatively; in the four non-criminal trials, the plaintiffs express attitude most frequently and most negatively. In the debate section of criminal trials, judgements of legality and capacity and non-judgement invoking appreciations are employed by the prosecutors and defense attorneys to express attitude and debate each other. Non-judgement invoking appreciations are used not only to evaluate the evidence, but also to introduce substantial statements, serving as an intermediate link between the two.

Published: April 2018

Paraneoplastic movement disorders are rare, autoimmune-mediated, nonmetastatic complications of malignant neoplasms. Common paraneoplastic movement disorders include paraneoplastic chorea, dystonia, cerebellar degeneration, different types of encephalitis, opsoclonus-myoclonus syndrome, stiff person syndrome, and neuromyotonia. Syndromes usually develop before tumor diagnosis, have subacute onset, and are associated with serum or cerebrospinal fluid antibodies. Two types of antibodies can be distinguished: antibodies against nuclear and cytoplasmic neuronal antigens (anti-Hu, anti-Ri, anti-Yo, anti-Ma, anti-CV2/CRMP5, anti-Gephrin, and anti-GABATRAP) and antibodies recently identified against cell surface and synaptic proteins (anti-NMDAR, anti-LGI1, and anti-Caspr2). These two types differ from each other in a few important aspects. Antibodies against cell surface and synaptic protein disrupt cell-surface antigens. Clinical symptoms are related to the disruption of antigens and potentially can be reversed by immunotherapy. The association between these antibodies and malignancy is much less consistent. On the other hand, antibodies against nuclear and cytoplasmic neuronal antigens seem to be not pathogenic; however, they most likely indicate a T-cell-mediated immune response against neurons. Due to T-cell-mediated neuronal loss, response to immunotherapy is generally disappointing. Early recognition of all these diseases is crucial because it may lead to the disclosure of occult cancer. This review is focused on paraneoplastic movement disorders with emphasis on clinical presentations, investigational findings, and therapeutic results.
Migration Effects on Municipalities’ Expenditures
Authors: Mäkelä Erik , Viren Matti
Published: April 2018

In this paper we examine how Finnish municipalities’ expenditures depend on the demographic structure of the population. More precisely, we scrutinize the role of foreign citizens: how does the share of citizens with foreign background out of the total population manifest itself in total expenditures and some key expenditure categories. The study makes use of Finnish panel data from 249 municipalities for the period 2000–2014. Empirical analyses show that foreign population tends to increase per capita expenditures up to the point where the respective semi-elasticity is about one. The result seems robust in terms of different control variables, subsamples of the data and different estimation techniques. Also, it is found that the unemployment rate of foreign citizens tends to increase municipalities’ expenditures. Thus, opposite to standard assumptions, per capita public consumption expenditures do depend on migration and that should be taken into account when making assessments on overall fiscal effects of migration. From political economy point of view, these results seem to be at variance with the “non-willingness to pay other ethnic groups’ expenditures” hypothesis that has been put forward by e. g. Alberto Alesina and Assaf Razin.
A conversation analytic study of error correction outside of the second language classroom
Authors: David Virginia
Published: April 2018

This study investigates repair sequences between two nonnative speakers of English while they engaged in naturally occurring talk outside of the second language classroom. Eight hours of naturally occurring talk between native and nonnative speakers were collected and analyzed. The present study reports on one hour of the data which shows two types of repair: Self-initiated and other-corrected and other-initiated. The analysis of the repair sequences shows that the self-initiated and other-corrected repair sequences follow a distinct pattern of asking for confirmation on the production of a language item and receiving a correction, while the other-initiated repair is done differently from the ones found in the literature on repair and do not follow the rules of preference for self-correction described by some researchers in the Conversation Analysis literature. In addition, the other-initiated repair analyzed in this study does not appear to be modulated, that is, the person initiating the correction does not offer a candidate solution by asking a question and displaying uncertainty, as researchers found. The repair sequences show a particularly interesting expert-novice relationship in which one nonnative speaker relies on a more expert nonnative speaker to communicate with a native English speaker.
Semiotic resources for navigation: A video ethnographic study of blind people’s uses of the white cane and a guide dog for navigating in urban areas
Authors: Due Brian , Lange Simon
Published: April 2018

This paper describes two typical semiotic resources blind people use when navigating in urban areas. Everyone makes use of a variety of interpretive semiotic resources and senses when navigating. For sighted individuals, this especially involves sight. Blind people, however, must rely on everything else than sight, thereby substituting sight with other modalities and distributing the navigational work to other semiotic resources. Based on a large corpus of fieldwork among blind people in Denmark, undertaking observations, interviews, and video recordings of their naturally occurring practices of walking and navigating, this paper shows how two prototypical types of semiotic resources function as helpful cognitive extensions: the guide dog and the white cane. This paper takes its theoretical and methodological perspective from EMCA multimodal interaction analysis.

Taken into consideration that molecular and cellular mechanisms involved in cardiotoxicity are still not clear the aim of this study was to compare the production of oxidative stress parameters in the isolated rat heart between animals chronically treated with cisplatin and saline. The hearts of male Wistar albino rats (n = 24, 12 per group, age 8 weeks, body mass 250±50 g) were excised and perfused according to the Langendorff technique at gradually increased coronary perfusion pressures (40-120 cm H2O). We followed the production of superoxide anion radicals, hydrogen peroxide, and nitrites and also index of lipid peroxidation during the changes of coronary perfusion pressure (CPP) (from 40 to 120 cm H2O) in coronary venous effluent. Modifications CPP were performed in order to determined if oxidative stress is involved in coronary endothelium response in conditions of hypoxia (lower than 60 cm H2O) and hyperoxia (higher than 80 cm H2O).

Based on the results of this research we can conclude that with enhancement of CPP the values of oxidative stress statistically increased. However, this increment is more prominent in control group as a result of preserved endothelium and its more powerful response to hyperoxia. On the other hand, damaged endothelium of cisplatin-treated animals had weaker response to hyperoxia, and also lower antioxidant capacity.

The bleeding from the upper gastrointestinal tract represent a significant medical but also socio-economic problem.A special group of patients et increased risk consists of critically ill patients in intensive care units. Particularly significant cause of bleeding in intensive care unit patients is bleeding resulting from the stress ulcers caused by damage of themucosa of the stomach and duodenum. The purpose of this review is to present current experience in prevention of upper gastrointestinal tract bleeding using proton pump inhibitors in intensive care units. Combination of endoscopic hemostatic methods and proton pump inhibitors represents golden standard in most cases. Despite some adverse effects treatment with proton pump blockers is essential when upper gastrointestinal tract bleeding appears in critically ill patients in intensive care units. Proton pump inhibitors are more effective in acid suppression, as well as in the prevention of recurrent bleeding after endoscopic hemostasis than histamine 2 receptor blockers. The efficacy of proton pump blockers is higher in the case of a continuous intravenous infusion than in the intermittent mode of administration of the drug. The need for highly elaborate strategy for the prophylaxis of bleeding from the upper parts of gastrointestinal tract in intensive care units is essential, because when it occurs in intensive care units, mortality is high, and therapeutic options become narrow.
The Border Monster Refuses to Die
Authors: Zajc Marko
Published: April 2018

The author contextualizes the Final Award issued on 29 June 2017 by the Permanent Court of Arbitration in The Hague on the Slovenian-Croatian border dispute, a dispute which began in 1991 when the two Yugoslav republics became independent states. After joining the European Union in 2004, Slovenia began to use its membership to attempt to force its neighbour to agree to its terms. In November 2009 the two countries signed an Arbitration Agreement that temporarily solved the problem. The Final Award of the Court of Arbitration in The Hague of June 2017 has not been acknowledged by Croatia, though, on the ground of an audio surveillance scandal in 2015 that involved a Slovenian arbitrator. The Slovenian side has advocated the Final Award of the Tribunal as the only legal, internationally binding, and “European” solution to the border question, while the Croatian side continues to ignore the tribunal’s disposition.
Estimation of Gas Turbine Unmeasured Variables for an Online Monitoring System
Authors: Loboda Igor , Miró Zárate Luis Angel , Yepifanov Sergiy , Maravilla Herrera Cristhian , Pérez Ruiz Juan Luis
Published: April 2018

One of the main functions of gas turbine monitoring is to estimate important unmeasured variables, for instance, thrust and power. Existing methods are too complex for an online monitoring system. Moreover, they do not extract diagnostic features from the estimated variables, making them unusable for diagnostics. Two of our previous studies began to address the problem of “light” algorithms for online estimation of unmeasured variables. The first study deals with models for unmeasured thermal boundary conditions of a turbine blade. These models allow an enhanced prediction of blade lifetime and are sufficiently simple to be used online. The second study introduces unmeasured variable deviations and proves their applicability. However, the algorithms developed were dependent on a specific engine and a specific variable. The present paper proposes a universal algorithm to estimate and monitor any unmeasured gas turbine variables. This algorithm is based on simple data-driven models and can be used in online monitoring systems. It is evaluated on real data of two different engines affected by compressor fouling. The results prove that the estimates of unmeasured variables are sufficiently accurate, and the deviations of these variables are good diagnostic features. Thus, the algorithm is ready for practical implementation.
Recherchen zu „Teil II“ der Philosophischen Untersuchungen und zur von Wittgenstein erstellten „C-Sammlung“ im Nachlass
Authors: Rothhaupt Josef G. F.
Published: April 2018

In 1953 — two years after Wittgenstein’s death — the Philosophical Investigations as we know them today have been published in a bilingual (German-English) edition by Elizabeth Anscombe and Rush Rhees. This publication is divided into two parts – entitled “Part I” and “Part II”. In the revised 4th edition by Peter Hacker and Joachim Schulte from 2009 the title “Part II” was deleted and renamed to “Remarks on the Philosophy of Psychology — A Fragment”. This article presents some new research results about the genesis of the Philosophical Investigations in general and about “Part II” / “A Fragment” in particular. Furthermore, the so-called “C-Collection” arranged by Wittgenstein himself will be introduced in detail.
The Colour of the Elected: Determinants of the Political Under-Representation of Blacks and Browns in Brazil
Authors: Campos Luiz Augusto , Machado Carlos
Published: April 2018

It appears to be beyond dispute that Brazilian politics is overwhelmingly White. Recent surveys indicate that the proportion of people of colour in the federal parliament is around 20%. But despite such obvious marginalisation, little is known about the causes of this political under-representation. This paper attempts to shed light on the main filters driving out non-Whites, i.e. Blacks and Browns, from Brazilian politics. To this end, we have carried out a survey of the skin colour of candidates to a seat in the City Council of Brazil’s two largest cities: São Paulo and Rio de Janeiro, in the 2012 elections. Given the lack of official records on the race or skin colour of these candidates, we chose to submit their photos, made publicly available by the Supreme Electoral Court, to classification by a team of researchers. The results have allowed us to gauge the extent to which the political alienation of non-White Brazilians is due to: (a) bias in party recruitment; (b) differences in educational capital and personal wealth between White and non-White candidates; (c) inequalities in the distribution of party and electoral resources; or (d) the electoral preferences of voters themselves. Apparently, the electoral opportunities of Blacks and Browns reflect the difficulties that these groups face when trying to ascend to the small elite of candidates that have the biggest funding and the most votes.
“What an inauspicious moment it turned out to be when she began to write!”: The Presentation and Position of the South Asian Woman Writer in Colonial Bengal
Authors: Hall Danielle
Published: April 2018

This paper addresses the position and culturally loaded presentation of the South Asian woman writer in two colonial Bengali texts. Through a comparative analysis of Rabindranath Tagore’s “Nashtanir” (1901) and Rokeya Sakhawat Hossain’s Sultana’s Dream (1905), it explores the way in which both texts sought to engage with debates surrounding the education of women in the early twentieth century. It argues that the development of Charu’s extra-marital relationship in “Nashtanir,” coupled with Tagore’s representation of her as simple, superficial, and dangerous, gave weight to the claim that women’s education may contribute to a waning interest in domestic duties and facilitate the capacity to engage in extra-marital relationships. However, the analysis of Sultana’s Dream alternatively shows that the woman writer in colonial Bengal used her position to protest the barriers to women’s education in this context. By generating a text that invited its readers to engage in wider educational practises, Hossain produced a politically charged appeal which served to challenge misconceptions surrounding women’s education in colonial Bengal.
Negotiating Gender, Memory, and History in Anita Desai’s Clear Light of Day
Authors: Khan Sayma
Published: April 2018

Anita Desai’s novel Clear Light of Day, published 33 years after the Indian subcontinent’s Partition, lays its focus on markedly ‘female’ experiences of Partition, wherein the importance of national history is negotiated within the framework of gendered family history. What role such familial (social) memories play within the larger canon of ‘Partition narratives’ will be analyzed exemplarily through the novel in this paper. Looking at the way the family house is depicted in Clear Light of Day is important to mark out its chronotopic value, i.e. the house contains as well as evokes spatial memories and triggers the mnemonic processes of the female protagonists that eventually facilitate the overcoming of past conflicts. Finally, the narrative technique of internal focalization, repeatedly deployed in the novel, will be scrutinized in order to reveal the inner turmoils and the personal (traumatic) experiences of the female protagonists.
Protest als diskursive Raum-Zeit-Aneignung. Das Beispiel der Identitären Bewegung Österreich
Authors: Bendl Christian
Published: April 2018

This paper deals with the Identitarian Movement, a presently highly salient Europe-wide right-wing youth movement, and its appropriation of the concepts of ‘space’ and ‘time’ in acts of protest. This appropriation is crucial for the movement, as ‘space’ and ‘time’ refer to specific ideologies which allow a positioning towards events, actors and discourses. In this study interdisciplinary approaches are adapted that lead to a descriptive linguistic discourse analysis of a single protest event. In order to enable an extensive and in-depth analysis, this single protest event is split up in three parts: 1. The announcement of the protest, 2. its performance in a place and 3. the continuation of the protest in/through social media. The findings argue to take the ideologization of history, places and actors into account when discussing the identity-building concepts and, especially, when undertaking critical and political follow-up studies of such movements.
Das Semikolon als Kohäsionsmittel. Eine Korpusstudie in der überregionalen Pressesprache
Authors: Gillmann Melitta
Published: April 2018

Drawing on a corpus study conducted using the German national newspaper DIE ZEIT, the paper studies usage contexts of the semicolon, considering syntactic as well as text linguistic factors. In the vast majority of cases, the semicolon is found to connect main clauses; the linkage of subordinate clauses and nominal phrases is significantly less frequent. Moreover, the average semicolon sentence is significantly longer and structurally more complex than the average sentence of the same corpus. However, the sentence elements connected by the semicolon are shorter and less complex than average sentences.

The main claim of the article is that the semicolon marks coherence between two clauses. For the most part, the event expressed in the second clause is in some respect similar or equivalent to the first one or provides an explanation, an example or a reason. Less frequently, the second clause denotes a result, implies a contrast or operates in a speech-act domain. While these relations usually are not expressed explicitly by a connector, the coherence is often reflected by co-reference chains extending across both clauses.
Morphosyntaktische Variation in Verbalkomplexen des Verbslassenund der Modalverben im Infinitiv II. Eine Analyse aus der Perspektive von Zentrum und Peripherie
Authors: Dovalil Vít
Published: April 2018

This paper deals with a morphosyntactic variable of German verb clusters containing a full verb and an infinitive perfect of the verblassenor of modal verbs (gelassen haben, gekonnt haben). The corpus-based analysis draws upon the concept of center and periphery as it was developed by the Prague School. The main research question underpinning the synchronic analysis concentrates on the use of the IPP (infinitivus pro participioequivalent to the German termErsatzinfinitiv) and the word order of the auxiliary verb within the cluster. In total, there is empirical evidence for four variants in which this variable is realized. Two of them fully correspond to the system of German infinitive constructions (full verb +gelassen/gekonnt haben, orhaben+ full verb + IPPlassen/können). However, these systemic constructions are used (much) less frequently in contemporary written German than the other two constructions (past participle of full verb +haben+lassen/können, or full verb +haben lassen/können). Whereas the former ones can be counted to the center of the German infinitive system from the structural point of view, the latter ones are classified as peripheral, because they are not derivable from the rules of this system. In spite of that, the paper explores one of identifiable epicenters within the periphery of the system, arguing with the highest frequency and further regularities of the third type of the construction (past particple of full verb +haben+lassen/können). The structural analysis takes the functional equivalency of subordinate clauses and the corresponding infinitive constructions into consideration. This contributes to better clarification of both morphology and word order of the elements creating the analyzed verb clusters.
Experimental Analysis of the Thermo-Hydraulic Performance on a Cylindrical Parabolic Concentrating Solar Water Heater with Twisted Tape Inserts in an Absorber Tube
Authors: Kumar Birendra , Nayak Rajen Kumar , Singh S.N.
Published: April 2018

A twisted tape inserted in an absorber tube may be an excellent option to enhance the performance of a cylindrical parabolic concentrating solar collector (CPC). The present work is an experimental study of the flow and heat transfer with and without twisted tape inserts in the absorber tube of a CPC. Results are presented for mass flow rates of water, ṁ=0.0198–0.0525 kg/s, twist ratio, y=5–10 and Reynolds number, Re=2577.46–6785.55. In the present study, we found that the outlet water temperature, collector efficiency and Nusselt number (Nu) are higher in the twisted tapes as compared to those without the twisted tape inserts in the absorber tube of the CPC. For fixed mass flow rate of water ṁ, the T
o

and η increased with the decrease in twist ratio, y, and is higher in lower twist ratio, y=5, of the twisted tapes. The whole experiment was performed at the Indian Institute of Technology (ISM) in Dhanbad, India during the months of March–April 2017. Based on the experimental data, the correlations for the Nu and friction factor were also developed.

Cuerpo, trópico y tiempo: elementos de creación identitaria en la poesía de Nicolás Guillén
Authors: Farías Rangel Gerardo
Published: April 2018

El siguiente artículo aborda la obra del poeta cubano Nicolás Guillén, tomando como base el poemario West Indies Ltd., publicado por primera vez en 1934, además de tomar en cuenta otros poemas de su producción anterior y posterior, con la finalidad de analizar su propuesta de creación de una nueva identidad, una ontología telúrica, fundamentada en lo material, por sobre lo metafísico, como respuesta a una serie de cuestionamientos existenciales que parten desde el interior del yo lírico, el cual usa el cuerpo y su relación con el trópico, y el tiempo como base fundamental de su creación poética.
1922: acercamiento a los contextos y alrededores de Trilce
Authors: Rodríguez Sánchez Diana
Published: April 2018

El presente análisis tiene como finalidad realizar un acercamiento al poemario Trilce, de César Vallejo, a partir de su relación con el contexto y las lecturas próximas a 1922, año de su publicación. En los albores del siglo XX, el hombre moderno cuestiona los discursos impuestos por la lógica y la razón, bajo una tradición que hizo de la metafísica el único camino de conocimiento del ser. Los alrededores a los que se acude son el poema La tierra baldía y enfoques que abordan la crisis del sujeto y la posición radical del lenguaje, con el propósito de ofrecer posibles rutas de lectura acerca del poemario.
Michel de Montaigne: una crítica de la modernidad desde la reconciliación con la finitud
Authors: Palacios Cruz Víctor H.
Published: April 2018

Montaigne traza una conciencia de la individualidad en un punto medio que evita tanto la deploración del yo del luteranismo como la absolutización de la razón del cartesianismo. Somos un punto en el tiempo y el espacio, pequeñez que desestima cualquier divinización del juicio personal y, de paso, explica la pluralidad del mundo. Pequeñez que alienta tanto el trato con la interioridad como el interés por los otros.
