Die postmigrantische Gesellschaft
Authors: Foroutan Naika
Published: July 2019

Das Erstarken rechtspopulistischer Bewegungen führt zu einer Normverschiebung in europäischen Gesellschaften und erzeugt Spannungen, die sich in Polarisierung widerspiegeln. Es geht dabei weniger um Migration selbst als um die Prozesse, die stattfinden, wenn Migrant*innen und ihre Nachkommen ihre Rechte einfordern. Die Frage des Umgangs mit Migration wird so zur Chiffre für Anerkennung von Gleichheit in demokratischen Gesellschaften. Naika Foroutan zeigt, dass die Migrationsfrage zur neuen sozialen Frage geworden ist - an ihr werden Verteilungsgerechtigkeit und kulturelle Selbstbeschreibung ebenso wie die demokratische Verfasstheit verhandelt. »Wie hältst Du es mit der Migration?« steht für die Frage danach, was ausgehandelt werden muss, damit die plurale Demokratie zusammenhält. Die postmigrantische Gesellschaft ist also eine, die sich im Kontext der Debatten um den Stellenwert von Migration neu ordnet.
Europa mit schwerer Havarie bei Merle Kröger
Authors: Giovannini Elena
Published: July 2019

Ein YouTube-Video über die Begegnung eines Kreuzfahrtschiffes mit einem Flüchtlingsboot hat der Schriftstellerin, Drehbuchautorin und Filmproduzentin Merle Kröger den Anlass zu ihrem Roman »Havarie« (2015) gegeben. Die Lebensabschnitte von elf Figuren (Migranten, Urlaubern, Kreuzfahrtschiffs-, Seenotrettungs- und Frachtarbeitern) kreuzen sich in einem Zeitraum von zwei Nächten und einem Tag im Mittelmeer; das Zusammenprallen unterschiedlicher Welten, das aus diesen Begegnungen entsteht, wird aus den sich abwechselnden Perspektiven aller Hauptfiguren nüchtern und schonungslos erzählt. »Havarie« ist aber nicht nur ein Roman der Jetztzeit, der die Migrantenwelle aus Afrika darstellt, sondern wegen seiner Anspielungen auf Konflikte u. a. in der Ukraine, Algerien, Syrien, Nordirland und in den Philippinen, die Schwarz-Weiß-Bilder am Ende des Bandes visuell darstellen, auch einer der jüngsten Weltgeschichte. Da Geschichte »nicht nur in der Zeit, sondern auch im Raum« spielt (Schlögel), gewinnt vor allem das Meer eine tragende Funktion, sowohl als permeabler Grenz- und Übergangsraum als auch als Landschaft mit unsichtbaren und trotzdem deutlichen Abgrenzungen, die zeigt, dass das besitzanzeigende Adjektiv in der Bezeichnung mare nostrum die Konnotation der Inklusion und der Gemeinsamkeit zugunsten der Exklusion und der Alterität verloren hat. Unter den Schiffen und Booten, die das Mittelmeer durchkreuzen, spielt das Kreuzfahrtschiff eine besonders wichtige Rolle: Es stellt einen mehrsprachigen Mikrokosmos dar, der - wie sein Name »The Spirit of Europe« verrät - das Wesen eines Erdteiles synthetisiert und die soziale Ungleichheit, die Ausbeutung, die Gleichgültigkeit, die Geldgier, die Kontaktarmut, die Oberflächigkeit und den Egoismus bloßstellt, die ihn kennzeichnen: Havariert ist also nicht nur das Schlauchboot der Flüchtlinge, sondern auch Europa und der Mensch. Wichtig ist schließlich die literarische Gattung, der »Havarie« angehört: Der Text ist ein Kriminalroman, der monatelang auf Platz 1 der Krimi-Bestenliste der Zeit stand. Vermisst wird Jo, ein philippinischer Sänger des Kreuzfahrtschiffes, aber der traditionelle Ablauf eines Krimis fehlt fast genauso wie die Ermittlung und die Ermittlerfigur. Das Verbrechen steht aber fest: mehrfacher Mord. An Jo (vielleicht), an den Flüchtlingen, die das Mittelmeer zum Massengrab werden lassen, und an der Menschlichkeit. Die zentrale Frage der Kriminalliteratur »whodunit?« (Alewyn) bleibt, und ihre Beantwortung wird dem Leser und seinem Gewissen überlassen. Ist aber der Leser als Europäer und Mensch nicht selber ein Mörder?
Persōnlichkeitsschutz im digitalen Umfeld in Zeiten der Mehrebenenregulierung
Authors: Specht-Riemenschneider Louisa , Jennessen Dennis
Published: July 2019

Louisa Specht-Riemenscheider und Dennis Jennessen widmen sich in ihrem Beitrag dem Verhältnis von KUG und DS-GVO. Hierzu legen die Verfasser zunächst dar, warum der Bildnisschutz - und damit auch das KUG als dessen einfachgesetzliche Ausgestaltung - mit Inkrafttreten der DS-GVO verstärkt in einen datenschutzrechtlichen Kontext rückt und es somit zu einer Konkurrenz beider Regelungsregime kommt. Anhand einer Untersuchung der Reichweite einzelner Öffnungsklauseln zeigen sie sodann auf, in welchen Bereichen der Bilddatenverarbeitung das KUG trotz des europäischen Anwendungsvorrangs unverändert fortgelten kann. Anschließend gehen sie dezidiert auf die Konsequenzen in der Rechtsanwendung ein, die sich daraus ergeben können, dass das KUG für einzelne Teilbereiche nicht mehr unmittelbar gilt. Hierzu arbeiten die Verfasser verschiedene Teilaspekte bei der Verarbeitung personenbezogener Bilddaten heraus und übertragen diese anschließend in das Regelungsgefüge der DS-GVO. Dabei gelangen sie zu dem Ergebnis, dass sich die Wertungen des KUG in die DS-GVO integrieren lassen.
Die Gesellschaft verändern
Authors: Bosse Jana
Published: July 2019

Soziale Bewegungen versuchen auf unterschiedlichen Wegen, gesellschaftlichen Wandel herbeizuführen. Jana Bosse erfasst anhand der empirischen Untersuchung von vier Basisgruppen der Umweltbewegung den komplexen Prozess der Strategieentwicklung und zeigt: Anders als gedacht, sind Strategien nicht primär durch politische Möglichkeitsfenster oder vorhandene Ressourcen bestimmt. Vielmehr sind sie durch die Theories of Change, also die Vorstellungen der Aktiven, sowie die Machtstruktur und Aufgabenverteilung in der Gruppe geprägt.
Energetic Forces as Aesthetic Forces
Authors: Siegmund Gerald
Published: July 2019

This paper argues that contemporary dance practices such as somatic practices or practices that work with ideas of transgression are based on what Michel Foucault in his seminal book The Order of Things (1966) has called the episteme of man, which according to Foulacult has been in opertaion since the late 18h century. Following Foucault today's practices are still based on the concept of a split and a doubleing of man into a visible and intelligible side of reason and a darker side governed by forces that wait to be brought to light. The fact that dance explores the unintelligible side of man has since been reformulated in various ways. Randy Martin's concept of mobilization that he proposed in his 1998 book Critical Moves is one prime example of this. In his book, Martin focuses on dance's infinite capacity to mobilize people to both produce dance and to assemble for dance, which for Martin is also a political process. Being the grid rather than the movement, being the potential to move rather than movement in space and time, energy and mobilization align. Both are rallying calls for change and transformation, for different articulations of bodies and social kinesthetic energies. It is here that Martin's concept of mobilization meets the much older concept of the imagination or, Einbildungskraft, as an anthropological category more specific to the field of the arts. They both are impersonal non-subjectified vehicles for an open process of doing and undoing bodies.
Identitäten im Konflikt
Authors: Kretzschmar Katharina
Published: July 2019

»Nakba« bedeutet »Katastrophe« und bezeichnet aus arabischer Sicht die erste Eskalation des Konflikts zwischen Juden und Palästinensern 1948. Wer den heutigen Nahostkonflikt verstehen will, muss auch die Bedeutung der Nakba als wichtigen Bestandteil des palästinensischen Selbstverständnisses und die damit verbundene intergenerationelle Weitergabe von Erinnerungen berücksichtigen. Den Einfluss dieses Erbes auf die sogenannte dritte Generation untersucht Katharina Kretzschmar interdisziplinär anhand ausführlicher biografischer Interviews mit Palästinensern aus Israel, der Westbank und dem Gazastreifen. Ihre Interviewpartner gehören der Generation an, die die Zukunft des Nahen Ostens maßgeblich mitgestalten wird. Mit einem Vorwort von Wolfgang Benz.
Lust und Limit
Authors: Majewska Magda
Published: July 2019

Sexualität als Brennpunkt des Konflikts zwischen Kontrolle und Freiheit ist ein Schlüsselthema in den frühen Romanen der amerikanischen Postmoderne. Magda Majewska beleuchtet den Zusammenhang zwischen experimenteller literarischer Praxis, Kulturkritik und Sexualität am Beispiel von Thomas Pynchons Gravity's Rainbow und William S. Burroughs' Naked Lunch. Dabei rekonstruiert sie das Verhältnis von Trieb und Kultur in den beiden Romanen vor dem Hintergrund freudomarxistischer Diskurse der sexuellen Befreiung und ihrer Bedeutung für die amerikanische Gegenkultur. Erst diese ideengeschichtliche Einbettung erlaubt es, die Welthaltigkeit und politische Stoßkraft des postmodernen Romans offenzulegen.
Creation of Optimal Performance of the Investment Project
Authors: Volarević Hrvoje
Published: July 2019

The selection of an investment project is seen as a problem of multi-criteria decision-making. In this paper, a decision-maker uses six attributes i.e. criteria most used by the international companies in practice (net present value, internal rate of return, payback period, accounting rate of return, operating profit margin and return on equity).

Individual utility functions are made for each attribute separately and the global utility function as a weighted sum of individual utility functions. For each criterion a final set of arranged pairs i.e. points of utility is determined based on the decision-maker’s assessments. Then, the points obtained are approximated by the utility function.

Finally, the optimization issue solved in order to obtain the optimal performance of the selected project according to decision-maker’s opinion. The negotiation procedure enables the offered performances to approach optimal performance of the selected project aimed at decision-maker and investor reaching an agreement.
DC pre-excitation starting control for induction motor base on flux identification and compensation
Authors: Fan Bo , Liu Leipo , Fu Zhumu , Fu Jiangtao
Published: July 2019

Vector control can not be well applied directly to the starting of large-power induction motors. The starting current is so large as to cause damage to power-conductors and the whole control system. A novel pre-excitation control strategy is proposed in this paper. A magnetic field is built in large power motor startup firstly, in which DC pre-excitation is adopted and the rotor flux orientation is set to coincide with the center line of motor’s one phase winding. With the completion of this pre-excitation, the control strategy is switched to the vector control. The excitation subsystem and the torque subsystem in the motor can be decoupled dynamically after this pre-excitation and vector control. The experimental results show that the motor’s starting current rises smoothly and its output torque has fast response. This control strategy is capable of reducing the motor’s starting current peak and improving the safety of induction motor’s startup.

We show how the advancements introduced around the new 5G mobile technology can address a wide range of industrial requirements. We further describe relevant use cases and develop an overall communication system architecture proposal, which is able to fulfill not only technical requirements but also system requirements, which result from specific applications existing in today’s and future manufacturing scenarios.
Systemarchitektur für die Implementierung proaktiver Verwaltungsschalen auf Basis kognitionswissenschaftlicher Konzepte
Authors: Schröder Tizian , Diedrich Christian
Published: July 2019

Der Digitalisierungsprozess hat durch die Initiative „Industrie 4.0“ an Bedeutung gewonnen. Eines der Kernkonzepte ist die Erstellung eines informationstechnischen Repräsentanten von Assets. Für diesen informationstechnischen Repräsentanten gibt es verschiedene Namen am Markt. Der Begriff der Verwaltungsschale wurde dafür durch die Plattform Industrie 4.0 geprägt. In den vergangen Jahren sind Dokumente und Aktivitäten um die Verwaltungsschale entstanden, die entweder Anforderungsbeschreibungen darstellen oder hinsichtlich ihres konkret umsetzbaren Gehaltes keine genügende Präzision haben. Der Beitrag leitet ausgehend vom Systembegriff und kognitionswissenschaftlichen Grundlagen die Systemarchitektur proaktiver Verwaltungsschalen ab. Diese Architektur zeigt auf, wie Verwaltungsschalen arbeiten müssten, um tatsächlich das Ziel der Industrie 4.0 verwirklichen zu können.
Political language patterns’ dissemination between a political leader and his campaign community: a CMC corpora analysis
Authors: Longhi Julien , Marinica Claudia , Després Zakarya
Published: July 2019

Political campaigns are important moments for a political personality, but for their campaigners as well. During this period, ideas flow between the two, and one can wonder how the discourse of a political personality is constructed and how they use what the campaigners say. This way, one can understand the rhetorical strategies of the political personalities during campaigns.

To answer these questions, in this paper we discuss the dissemination of political language patterns between a political personality and a campaign community, as a way to access political representations and ideological issues. In particular, this involves evaluating the polyphonic dimension of the discourse, widely described in enunciative linguistics, but rarely used in NLP works seeking to measure these phenomena. In this paper, we put forward an analysis methodology based on statistical computations which provides encouraging results.

We tested our methodology on the case of Jean-Luc Mélenchon, a French political personality, head of the France Insoumise party and candidate in the 2017 French presidential elections. We used two corpora: one composed of a set of tweets from Jean-Luc Mélenchon, and a second composed of two sets of data coming from two different forums used by the campaign community. In the study, we compare the results from both corpora to provide answers to the political question of the construction and circulation of political ideas, studying a movement with a charismatic leader and an important campaign community. From a linguistic point of view, we discuss the links between language elements, themes, ideologies, and the rhetoric dimensions of political discourse.
What you see is what you get: activity-based probes in single-cell analysis of enzymatic activities
Authors: Lentz Christian S.
Published: July 2019

Molecular imaging methods can provide spatio-temporal information about the distribution of biomolecules or biological processes, such as certain enzymatic activities, in single cells. Within a cell, it is possible to define the subcellular location of a target, its trafficking through the cell, colocalization with other biomolecules of interest and involvement in certain cell biological processes. On the other hand, single-cell imaging promises to distinguish cells that are phenotypically different from each other. The corresponding cellular diversity comprises the presence of functionally distinct cells in a population (‘phenotypic heterogeneity’), as well as dynamic cellular responses to external stimuli (‘phenotypic plasticity’), which is highly relevant, e.g. during cell differentiation, activation (of immune cells), or cell death. This review focuses on applications of a certain class of chemical probes, the so-called activity-based probes (ABPs), for visualization of enzymatic activities in the single-cell context. It discusses the structure of ABPs and other chemical probes, exemplary applications of ABPs in single-cell studies in human, mouse and bacterial systems and considerations to be made with regard to data interpretation.
Tooth wear patterns in subjects with class II division 1 and class II division 2 malocclusion
Authors: Agnani Sankalp , Bajaj Kamal , Mehta Siddharth , Pandey Lavesh
Published: July 2019

Introduction

There is an increasing trend of malocclusion among children, so it is necessary to identify the cause of the tooth wear so that the orthodontist can treat the patient accordingly. It is necessary to determine the wear patterns of different malocclusions. Therefore, the aim of our study was to compare the patterns of tooth wear among two categories of Angle’s class II malocclusions, i.e. class II division 1 and class II division 2.

Material and methods

The sample consisted of 100 pretreatment orthodontic patients in the age group of 15–25 years with Angle’s class II malocclusion and were divided into following two groups: (a) Group 1: 50 subjects with full cusp Angle’s class II division 1 malocclusion. (b) Group 2: 50 subjects with full cusp Angle’s class II division 2 malocclusion. Clinical examination of the patients for tooth wear was done supplemented with dental casts, intraoral photographs and intraoral radiographs. Then each group was assessed for severity of tooth wear according to modified tooth wear index (TWI) given by de Carvalo Sales-Peres et al. Scores were subjected to statistical analysis and the pattern of tooth wear among the two groups of class II malocclusion was compared. A correlation between the gender of the patient and the tooth wear was also determined. The level of statistical significance (p-value) was less than 0.05.

Results

The class II division 1 subjects showed statistically greater wear on the occlusal surfaces of the maxillary canines, first, second premolar and first molar, and the occlusal surfaces of the mandibular first molars. The class II division 2 subjects showed statistically greater tooth wear on the labial surfaces of the mandibular central and lateral incisors, the incisal surface of maxillary and mandibular incisors, the palatal surfaces of the maxillary second premolars, first and second molars. In class II division 1 subjects, the tooth wear was significant on the buccal surface of maxillary canines, occlusal surface of mandibular first premolars and second molars in males. In class II division 2 subjects, the tooth wear was significant on the buccal surface of mandibular canines, palatal surface of maxillary central incisors in females and palatal surface of maxillary first premolars in males.

Conclusions

The results of this study suggested that the two categories of Angle’s class II malocclusion have different tooth-wear patterns. The wear patterns were different in both the sexes. Men showed higher occlusal wear scores than did women. The findings also suggest that tooth wear in relation to malocclusion is physiologic and is due to dissimilar interocclusal arrangement.
Numerical Examination of the Entropic Energy Harvesting in a Magnetohydrodynamic Dissipative Flow of Stokes’ Second Problem: Utilization of the Gear-Generalized Differential Quadrature Method

Published: July 2019

The main purpose of this numerical investigation is to estimate energetically the thermo-magnetohydrodynamic (MHD) irreversibility arising in Stokes’ second problem by successfully applying the first and second thermodynamic laws to the unsteady MHD free convection flow of an electrically conducting dissipative fluid. This fluid flow is assumed to originate periodically in time over a vertical oscillatory plate which is heated with uniformly distributed temperature and flowing in the presence of viscous dissipation and Ohmic heating effects. Moreover, the mathematical model governing the studied flow is formulated in the form of dimensional partial differential equations (PDEs), which are transformed into non-dimensional ones with the help of appropriate mathematical transformations. The expressions of entropy generation and the Bejan number are also derived formally from the velocity and temperature fields. Mathematically, the resulting momentum and energy conservation equations are solved accurately by utilizing a novel hybrid numerical procedure called the Gear-Generalized Differential Quadrature Method (GGDQM). Furthermore, the velocity and temperature fields obtained numerically by the GGDQM are exploited thereafter for computing the entropy generation and Bejan number. Finally, the impacts of the various emerging flow parameters are emphasized and discussed in detail with the help of tabular and graphical illustrations. Our principal result is that the entropy generation is maximum near the oscillating boundary. In addition, this thermodynamic quantity can rise with increasing values of the Eckert number and the Prandtl number, whereas it can be reduced by increasing the magnetic parameter and the temperature difference parameter.
Erhöhen berufliche Lizenzen Verdienste und die Verdienstungleichheit?
Authors: Haupt Andreas
Published: July 2019

Für die Ausübung einiger Berufe in Deutschland ist eine staatliche Erlaubnis, eine sogenannte berufliche Lizenz, notwendig. Es ist bisher für Deutschland ungeklärt, auf welcher Grundlage diese Form beruflicher Geschlossenheit basiert und welche Konsequenzen sie für die Verdienststruktur hat. Der Artikel beschreibt, dass berufliche Lizenzierung in komplexe Institutionen eingebunden ist, die sowohl zur Regulation des Marktzutritts als auch zur Regulation der Preisbildung für berufliche Tätigkeiten führen. Die daraus resultierenden ökonomischen Vorteile lizenzierter Erwerbstätiger lassen sich am besten als Schutz nach unten deuten. Entgegen vorherrschender Annahmen sind Verdienstvorteile in den oberen Bereichen der Verteilung geringer als in den unteren Bereichen. Dadurch wird die Verdienstungleichheit in Deutschland insgesamt gesenkt. Resultate bedingter und unbedingter Quantilregressionen auf Basis der BIBB/BAuA-Erwerbstätigenbefragung von 2012 unterstützen beide Thesen.
Forensic Psychiatry in the largest security ward in Portugal
Authors: Carvalhão Teresa , Jorge Patricia , Batalim Paula
Published: July 2019

Forensic Psychiatry is defined as the Psychiatry subspecialty in which the clinical and scientific knowledge is applied to legal aspects, both with regard to Civil and Criminal Law. Nowadays, the largest security ward is in Coimbra, at the University Hospital. It covers 110 patients, 90 males and 20 females. The aim of the security measure, in accordance with the penal code, is the protection of legal assets and the psychosocial rehabilitation. In our sample, the main most frequent diagnosis was schizophrenia (37.8%). Moderate intellectual disability (23.4%) and mild intellectual disability (14.4%) were the second and third most frequent diagnosis. The unlawful acts that generated the prevalent security measure were in first place domestic violence (19,8%) followed by attempted murder (16,2%) and theft (14,5%). The elaboration of a therapeutic and rehabilitation plan is essential and its aim is to diminish the person’s dangerousness. It is fundamental to think of the safety ward as a health production space and not as a place of mere disease management or “dangerous states”, thus trying to solve the patient’s problems.

Authors: Zhu Jun , Xie Zhong-Qing , Gao Hong-liang , Zhan Xi-sheng
Published: July 2019

The journal bearing is a key and vulnerable component of a large diesel engine. Once the journal bearing fails to work, it is very difficult repair. On-line monitoring of the wear of the journal bearing has always been one of the research hotspots. Firstly, the monitoring mechanism of the thermoelectric method is discussed in the article. Secondly, the structural characteristics of a 6DK20 marine medium speed diesel engine are analyzed. Thirdly, by using the thermoelectric sensor designed by the research and development team led by the author, the parameters of typical wear state with load conditions are measured. Finally, the directivity of thermoelectric signals is analyzed, and the variation law of the peak value of thermoelectric signals is researched corresponding to the ignition point of time of the diesel engine under typical wear states with load conditions. The results show that the thermoelectric signals reflect the wear and running state of journal bearings and have good directivity and transient feature. Therefore, it has great research value and application value to the evaluation of the wear and failure of journal bearings by thermoelectric technology.
Laboratory Measurement of Excavation Disturbance Effect Due to Trenchless Construction Using Distributed Fiber Optics Strain Sensing
Authors: Li Yue , Wang Hao , Cai Jing , Song Ge
Published: July 2019

Excavation disturbance induced by trenchless construction may lead to underground movement and deformation, which can be a potential hazard to the safety of overlying pavement structure. However, the development of a fiber optic–distributed sensing approach in recent years has provide an effective way for continuous measurement of soil strain. In this study, the mechanism of the excavation disturbance effect that is due to trenchless construction was investigated based on laboratory experiments. The sensing fibers were embedded within the overburden layer above the excavation surface to measure the distributed soil strain using Brillouin optical time-domain analysis. The relationships between ground settlements and soil strains were analyzed. The partition theory of excavation disturbance zone was verified based on test results. The influence of excavation on mechanical responses of overlying model pavement, including bending deformation and soil pressure, was measured and discussed. Laboratory test results indicated that soil strains were nearly symmetrically distributed around the excavation area, which was compressive close to the centerline and then became tensile on both sides of the excavation area. The width of the excavation disturbance zone derived from the soil strain measurements was found close to the calculation results based on the partition theory. Because of the uneven distribution of the support force that was caused by foundation settlement, the model pavement showed notable bending deformation after excavation. Therefore, the combined effects of traffic loading and excavation disturbance should be considered in the safety evaluation of trenchless construction.
Design of Compliant Mechanism Microgripper Utilizing the Hoekens Straight Line Mechanism

Published: July 2019

Precision engineering industries demand devices with high-precision motion, the manipulation of micro-objects in particular, which is a highly challenging task. The microgripper is an essential device during the micromanipulation of objects. Precision manipulations of objects entirely depend on the design of the microgripper and are complicated to achieve using the conventional rigid link mechanism. The compliant mechanism is found to overcome the complexities of the rigid link mechanism in precision applications. The micro-object may slip or slide during gripping and releasing, which can be controlled through parallel movement of the gripping jaws. This research article focuses on the design of a compliant microgripper with parallel moving jaws by employing the Hoekens straight line mechanism. The Hoekens mechanism consists of binary and ternary revolute joints, which demand a special type of flexure hinges. Hence, the article introduces the cartwheel type of flexure hinges, as cartwheel-type flexure hinges are more suitable to achieve rotational deformation, values approximating nearly to that of the traditional revolute joint when it transfers motion between fixed and moving links. The outer rim of the cartwheel is modified to allow ternary and binary joints between moving links. Cartwheel is designed with curved flexure arms that are limited to eight numbers of flexures. The structural behavior of the cartwheel is analyzed by varying numbered flexures from 1 to 8. The minimum number of flexure arms required for having better rotational performance is determined through Finite Element Analysis (FEA). An appropriate type of cartwheel is positioned in the mechanism. The structural performance of the designed microgripper is carried out through FEA, and its parallel movement is verified. The microgripper is fabricated from structural steel through wire Electrical Discharge Machining (EDM) technique and actuated using Shape Memory Alloy wire. The displacement of the microgripper jaw is experimentally measured, and the results show a promising improvement.
Making Waves across the Pacific
Authors: Rees Yves
Published: July 2019

This article examines how women's broadcasting promoted consciousness and appreciation of the United States during the 1930s and 1940s. These were decades in which Australians had limited access to US news and culture, and Hollywood dominated local imaginings of US society. In this climate, Australians who had lived Stateside were hailed as authorities on the nation and its people, and they often spoke on radio. Among these “America educators” were significant numbers of women. Armed with firsthand knowledge of the wider world, these female travelers could claim space in a broadcasting landscape otherwise dominated by men. Through their radio broadcasts, they aspired to foster transpacific understanding and friendship. Women's broadcasting was therefore a cultural force at the vanguard of Australia's “turn to America.” More than a manifestation of US popular culture, radio depicted the United States as an ally of and model for Australia during an era of entrenched British allegiance.
Lessons from Lilian

Published: July 2019

Scholarship has long demonstrated how a focus on women's roles can reveal vital new elements of broadcasting history, adding critical perspectives on institutional, aesthetic, communicatory, and participatory media narratives. This article asks: What happens if we stop looking at the stories of women in broadcasting as “media history”? What other interpretive lenses and disciplinary traditions might we draw on, and how might we insert media fruitfully within them? The work derives from research on the early years of the International Association of Women in Radio and Television (IAWRT) as read from the correspondence of founder Wilhelmina (Lilian) Posthumus-van der Goot (1897–1989), and builds on IAWRT's example to develop methodological considerations for writing entangled transnational histories of gender and broadcasting, absorbing insights from studies of international organizations, collective biographies, and reconsiderations of the archive in the digital age.

The aims of this study were (i) to investigate changes in the global transcriptome of bovine endometrial explants induced by exposure to blastocysts, (ii) to investigate if male and female blastocysts elicit a differential response in the endometrial transcriptome in vitro and (iii) to determine whether bovine endometrium responds to the presence of murine embryos. In Experiment 1, endometrial explants from the same uterus were cultured for 6 h with or without 20 in vitro-produced bovine blastocysts. In Experiment 2, endometrial explants were cultured with male or female bovine blastocysts produced in vitro by IVF either using sex-sorted semen or conventional unsorted semen followed by embryo sexing based on a biopsy. In Experiment 3, endometrial explants were cultured alone or in the presence of bovine blastocysts (n = 25) or murine blastocysts (n = 25). Following culture, explants were snap frozen and stored at −80°C until RNA extraction, qPCR or RNA-Seq. Culture with bovine blastocysts increased endometrial expression of 40 transcripts, all of which were interferon-tau induced. Culture with male or female bovine blastocysts increased transcript abundance of five classic interferon-stimulated genes (MX1, MX2, ISG15, OASY1, RSAD2) in explants; however, there was no difference in abundance of transcripts previously reported to be related to embryonic sex (IFNAR1, IFNAR2, CTGF, ARTN, SLC2A1, SLC2A5). Exposure to murine blastocysts did not elicit any detectable change in transcript abundance. These findings, coupled with our previous data, indicate that very local, interferon-tau-induced changes in endometrial gene expression occur in response to blastocysts; whether such changes play any role in subsequent pregnancy recognition remains to be established.
Optimal harvesting policy of a prey–predator model with Crowley–Martin-type functional response and stage structure in the predator
Authors: Dubey Balram , Agarwal Shikhar , Kumar Ankit
Published: July 2019

In this paper, a three-dimensional dynamical model consisting of a prey, a mature predator, and an immature predator is proposed and analysed. The interaction between prey and mature predator is assumed to be of the Crowley–Martin type, and both the prey and mature predator are harvested according to catch-per-unit-effort (CPUE) hypothesis. Steady state of the system is obtained, stability analysis (local and global both) are discussed to explore the long-time behaviour of the system. The optimal harvesting policy is also discussed with the help of Pontryagin's maximum principle. The harvesting effort is taken as an effective control instrument to preserve prey and predator and to maintain them at an optimal level.
Finite-time synchronization of Markovian neural networks with proportional delays and discontinuous activations

Published: July 2019

In this paper, finite-time synchronization of neural networks (NNs) with discontinuous activation functions (DAFs), Markovian switching, and proportional delays is studied in the framework of Filippov solution. Since proportional delay is unbounded and different from infinite-time distributed delay and classical finite-time analytical techniques are not applicable anymore, new 1-norm analytical techniques are developed. Controllers with and without the sign function are designed to overcome the effects of the uncertainties induced by Filippov solutions and further synchronize the considered NNs in a finite time. By designing new Lyapunov functionals and using M-matrix method, sufficient conditions are derived to guarantee that the considered NNs realize synchronization in a settling time without introducing any free parameters. It is shown that, though the proportional delay can be unbounded, complete synchronization can still be realized, and the settling time can be explicitly estimated. Moreover, it is discovered that controllers with sign function can reduce the control gains, while controllers without the sign function can overcome chattering phenomenon. Finally, numerical simulations are given to show the effectiveness of theoretical results.

Published: July 2019

In this paper, we present new schemes to synchronize different dimensional chaotic and hyperchaotic systems. Based on coexistence of generalized synchronization (GS) and inverse generalized synchronization (IGS), a new type of hybrid chaos synchronization is constructed. Using Lyapunov stability theory and stability theory of linear continuous-time systems, some sufficient conditions are derived to prove the coexistence of generalized synchronization and inverse generalized synchronization between 3D master chaotic system and 4D slave hyperchaotic system. Finally, two numerical examples are illustrated with the aim to show the effectiveness of the approaches developed herein.

Originality/Value. We have devised a classification of the marketing function at an enterprise. The basic principles of marketing function have been substantiated. We have defined the methodological provisions for studying the marketing function at an enterprise. The essence, content, and structure of innovative marketing have been determined as an important and integral component of conducting an economic activity by an enterprise, which implies the creation of a fundamentally new product (good, technology, service); the application of innovative marketing has been emphasized for improving business processes at an enterprise.
Research limitations/Future research. The task is to develop an effective mechanism for the efficient functioning of marketing under different situational and market-led fluctuations under conditions of market volatility.

On weakly ℌ-embedded subgroups and p-nilpotence of finite groups
Authors: Asaad Mohamed
Published: July 2019

Let G be a finite group and H a subgroup of G. We say that H is an ℌ-subgroup of G if NG (H) ∩ Hg ≤ H for all g ∈G; H is called weakly ℌ-embedded in G if G has a normal subgroup K such that HG = HK and H ∩ K is an ℌ-subgroup of G, where HG is the normal clousre of H in G, i. e., HG = 〈Hg|g ∈ G〉. In this paper, we study the p-nilpotence of a group G under the assumption that every subgroup of order d of a Sylow p-subgroup P of G with 1 < d < |P| is weakly ℌ-embedded in G. Many known results related to p-nilpotence of a group G are generalized.
The Environmental Assessment of Urban Agglomerations on the Basis of Sustainable Development Indicators
Authors: Ivantsova Elena , Postnova Margarita , Sagalaev Vadim , Matveeva Anna , Kholodenko Anna
Published: July 2019

The article discusses the indicators of sustainable development given from the standpoint of the classical concept of sustainable development. The methods used are analyzed to identify criteria for sustainable development. The indicators of sustainable development have been known and developed for a long time. However, their development did not take into account the regional fix, which would allow creating a permanent set of the most representative indicators for a certain territory. Volgograd and Rostov agglomerations are chosen as objects. A complex analysis of the regional indicators of sustainable development is carried out taking into account physiographic, climatic, sectoral features, the economic potential and ecological well-being of Volgograd and Rostov agglomerations. The work assesses the ecological and economic sustainability of the agglomerations under study, which allows to give the comparative analysis of the territory development predictive models. Today, it is still too early to talk about the effectiveness of achieving criteria for sustainable development in urban agglomerations. The accepted methods cannot be considered effective due to the fact that the efforts of all areas of management are needed. In the forecast, we can talk about a slight increase in the stability of Rostov agglomeration due to capital inflows. Taking into account current trends, Volgograd agglomeration can face a gradual decrease in sustainability requiring an immediate intervention.
The Rating Assessment of Food Security of the Southern Federal District Regions
Authors: Antamoshkina Elena
Published: July 2019

The article proposes the methodological tool and comprehensive indicator for assessing the food security of the regions. The index of food security is determined on the basis of the systematic groups of indicators. In the distribution of food products, the following indicators are analyzed: the indexes of food prices, the magnitude of the change in real incomes of the population, the population with incomes below the subsistence minimum. Among the indicators in the distribution of food products the volume of food consumption in accordance with rational consumption rates, the share of food expenditure in the structure of household consumption expenditures are considered. In the field of production the indexes of production of various types of agricultural products in the region are considered. The ranking of the Southern Federal District (SFD) regions by selected groups of indicators made it possible to determine the leaders in food security among the regions. In 2017, Krasnodar Krai, the Republic of Adygea and Rostov Region were among these regions. On the basis of the analysis performed, the authors established risks and threats in food supply of the SFD regions: imbalance of the consumer ration; decrease in real incomes and purchasing power of population; a high proportion of the population with incomes below the subsistence minimum in the region. The practical significance of the proposed approach lies in the possibility of justifying the choice of priority measures to optimize agrarian policy, taking into account the need to maintain an acceptable level of food provision in the regions of Russia.
The Problems and Conditions of Effective Public Participation in Creating a Smart Sustainable City
Authors: Matova Natal’ya
Published: July 2019

The technological arrangement of sustainable development ideas into modern life of cities is represented in the concept of a smart sustainable city. The evolution of smart settlements has convincingly proved that one of the key benefits of a smart city and, accordingly, a criterion for achieving smart sustainability, is the involvement and participation of citizens in public life. At the same time, it is important to understand that public participation is not only a criterion, but also a tool for achieving sustainable local development. Unfortunately, this fact is not adequately recognized by the domestic system of the public and municipal administration. As a result of the existing vision the Russian State strategy and the corresponding Programmes of introducing the concept of a smart sustainable city in municipal management practices appeared. This is happening the way that is traditional for our country: through the “top-down” introduction. Public participation, various institutional and informal forms of it face a number of problems in the current Russian conditions, which do not allow using the potential of social involvement in the formation of sustainable settlements to the fullest extent. The most important problems are the lack of public confidence in the institutions of power and the conviction that it is impossible to influence their actions, as well as the lack of knowledge and experience of self-organization of joint activities, insufficient awareness of their civil rights and forms of their realization, low level of self-awareness. Conclusion: the key condition for using modern organizational and economic tools to ensure the effective operation of communities, including the use of the “Smart city” project, is training, technology transfer, dissemination of knowledge and best practices, not only among inhabitants and activists, but also among officials and other decision-makers with public participation.
Economic and Mathematical Modeling of the Direct Effects of Large-Scale Infrastructure Projects on Developing Territories
Authors: Patrakeeva Olga
Published: July 2019

The problem of assessing the effects of infrastructure projects for territories is debatable. Modeling experience has been accumulated today, and elaborated macroeconomic models allow to identify causal relationships between the indicators of transport development and economic growth. The goal of this article is to define a simulation model of assessing the impact of transport projects on the economic growth of Krasnodar Krai exemplified by the Crimean Bridge project. The solution of this scientific problem requires taking into account different factors and complicated interrelationships within the framework of the regional social and economic system under consideration, using methods of system analysis and tools of economic and mathematical simulation. The simulation model reflects the scenario parameters of the capital management policy, highway transport freight turnover, highway transport freight turnover directly connected with the construction of Kerch Straight Bridge, carriage of goods by railway transport, carriage of goods by railway transport directly connected with the construction of Kerch Straight Bridge. The interrelations of this model’s parameters are established by the econometrics methods. In accordance with the produced scenarios the expected median values of the additional increment of the Krasnodar Krai GRP due to the increment of transportation associated with the Crimean Bridge operation are in the range between 0.97 % and 1.1 %. The most conservative scenario presumes the median value of 0.97 % and lower limit of 0.8 %. This tool can be used to assess the direct effect of railway and road construction for other Russian regions. The proposed simulation model will be further expanded by including further distribution functions of scenario variables and additional structural relationships.

Public Education and Non-statist Imaginaries
Authors: Suissa Judith
Published: July 2019

In this article, the author focuses on the statist imaginary associated with the defence of public education. Drawing on work on the idea of the public sphere, anarchist theory and the politics of movement, she argues that in a world characterised by unprecedented and growing levels
of mass migration and displacement, a new, nonstatist imaginary is needed. She explores some ways in which such imaginaries can play a role in educational thought and practice.
