Les clochers à terre
Authors: Hensel Florian
Published: May 2019

Lorsque résonne le clairon de l’Armistice, le 11 novembre 1918, une large partie de l’Alsace est en ruines. Le patrimoine religieux n’est pas épargné. Il a lui aussi subi d’importants dommages au cours des quatre années de conflit. Les différents types de destructions causées à ces édifices particuliers laissent entrevoir la complexité de la tâche qui attend désormais les équipes de reconstruction.C’est un état des lieux de ces bâtiments cultuels que nous nous proposons de dresser. Procédant de manière à la fois géographique, statistique, mais avant tout historique, nous présenterons l’impact de la guerre sur les clochers de la région. Nous nous attarderons d’une part sur la nature des dommages, mais également sur les mesures mises en place dans l’urgence pour faire face à des situations complexes. Réparations provisoires mais aussi destructions préventives ont parfois des conséquences à long terme sur la renaissance des villages alsaciens. Après ce temps de latence, des mesures plus durables sont cependant prises, avec notamment la mise sur pied de deux coopératives de reconstruction des églises. L’une dédiée aux édifices catholiques, l’autre aux édifices protestants.
La réintégration des monuments historiques de l’Alsace dans le patrimoine français :
Authors: Lefort Nicolas
Published: May 2019

Pendant la Grande Guerre et après le retour de l’Alsace à la France en 1918, les monuments historiques de la région sont instrumentalisés par la propagande et constituent un enjeu national entre France et Allemagne. Les Français considèrent les monuments d’architecture gothique comme des témoignages de l’influence pluriséculaire de la France en Alsace. Ils accusent les Allemands d’avoir négligé l’entretien des édifices d’architecture classique pour effacer la trace de la présence française dans le but de « germaniser » la région. Ils opposent de façon manichéenne et simpliste une méthode « française » de la conservation à une méthode « allemande » de la restauration. Ils présentent les grands travaux de restauration exécutés entre 1871 et 1918 comme des preuves de la « barbarie » et du « vandalisme » allemands.Au-delà du discours nationaliste, les Français utilisent différents moyens pour réintégrer les monuments historiques de l’Alsace dans le patrimoine national. Le gouvernement nomme des architectes parisiens à la tête des services d’architecture et des beaux-arts d’Alsace et de Lorraine et introduit rapidement la législation française sur les monuments historiques dans les territoires recouvrés. De grandes manifestations réunissent architectes, historiens de l’art et archéologues français en Alsace. La création d’une école régionale d’architecture à Strasbourg et l’organisation de grandes expositions doivent permettre à la France de rayonner à nouveau sur le Rhin. Enfin, la politique de protection des monuments historiques mise en œuvre en Alsace donne la priorité aux monuments considérés comme « français », tandis que les travaux de restauration exécutés après guerre cherchent à rétablir le caractère de certains monuments.
« Retour à la France » et « Plus grande France » :
Authors: Grandhomme Francis
Published: May 2019

« Pends-toi, brave Joseph, nous avons vaincu à Douaumont pendant que tu faisais la sieste à Tuyen-Quang ! »C’est ainsi que, dans Les Tilleuls de Lautenbach (1979), Jean Egen illustre un paradoxe : son père déserteur de l’armée allemande, versé au 3e Zouaves et affecté au Tonkin, n’apparaît pourtant pas un aussi « authentique » poilu dans son village que les combattants du front occidental. Aussi le fait colonial est une composante de l’après-guerre en Alsace.À ce titre, l’Exposition de 1924 veut convaincre les Alsaciens de leur appartenance à la France, nombre d’optants ayant participé aux conquêtes outre-mer, et sensibiliser tous les Français aux richesses de l’Empire. Loin de détourner Paris de la ligne bleue des Vosges, il est une des clés de la Victoire et de la paix face à l’Allemagne.Cet exotisme tricolore inspire aujourd’hui un malaise. L’Exposition, présentée comme un zoo humain, aurait formé un inconscient collectif source d’un racisme alsacien (Bourdieu, 1999). Le fait colonial est pourtant antérieur en Alsace, et aussi allemand.En revanche, il concerne un aspect du malaise alsacien d’après-guerre. Les « revenants » sont souvent d’anciens coloniaux tenants de l’assimilation et marqués par des stéréotypes (parfois d’ailleurs formés par des expositions d’Alsaciens ! – Nancy, 1909).
Les historiens français et l’Alsace en 1918, du sens au contresens
Authors: Bischoff Georges
Published: May 2019

La « guerre du Droit », à l’issue de laquelle l’Alsace redevient française a fortement mobilisé les historiens. En 1919, en affirmant qu’« une Histoire qui sert est une histoire serve », Lucien Febvre dénonce l’instrumentalisation du passé qu’il impute à la science allemande et lui oppose une sorte de neutralité distante, républicaine et laïque. Est‑ce effectivement le cas de ses collègues et de ses compatriotes qui ont construit le « roman national » en vigueur sous la IIIe République ? Le regard que l’historiographie française porte sur l’Alsace depuis 1871 mérite d’être analysé à travers les travaux de ceux qui lui consacrent leurs recherches et de ceux qui tentent de lui donner un sens, Renan, Fustel de Coulanges, Lavisse ou Henri Berr. Il n’est pas sûr, cependant, que cette lecture ait pris en compte des changements survenus au cours de la période.

Published: May 2019

The aim of this research was to study frequencies of playing live and digital games, and to test for gender differences, to identify the most frequently played games, and to explore association between well-being indicators and frequency of playing. We found low positive association between frequency of playing of live and digital games. Most frequently played live games were various card games, and Shooter games were most frequent among digital games. Male participants played more frequently both live and digital games. Male participants played more action and simulation computer games, while female participants preferred puzzles and card games. Internet addiction was positively correlated to the amount of time spent logged on to the internet, and higher levels of loneliness and depression. Participants who played live games more reported lower levels of depression. Participants who played digital games more, spent more time logged to the internet, reported higher levels of internet addiction, but lower levels of depression.

Published: May 2019

Since IBM released the Simon Personal Communicator in 1992, smartphones have brought modernization, convenience, communication, and revolution to human society. The smartphone has become inextricable from human beings due to its fantastic features and marvelous functions. With innumerable benefits, people are addicted to smartphones without knowing it. Many researchers have examined smartphone addiction, specifically the definitions, symptoms, criteria, risk factors, and consequences of smartphone addiction in the past decades; however, the intervention strategies and the effects of intervention for smartphone addiction are scant. More research is needed to help smartphone addicts and to avoid smartphone addiction in the long run. The purpose of this chapter is to provide an overview of the definitions, symptoms, criteria, reasons, and consequences for smartphone addiction as well as to explore intervention strategies for preventing smartphone addiction. Hopefully, this chapter will contribute to digital addiction a bit and help prevent smartphone addiction.
Determination of Plasticity for Pre-Deformed Billet
Authors: Solona Olena , Derevenko Iryna , Kupchuk Igor
Published: May 2019

The calculation procedure for determining the plasticity of pre-deformed metals during their processing by pressure has been developed. The calculation procedure is based on a fracture model, which in turn is based on the tensor description of damage accumulation. With known mechanical characteristics, as well as with known plasticity diagrams, the fracture model makes it possible to evaluate the plasticity of pre-deformed bend for any kind of stress state. When manufacturing steeply curved branches using the pipe extrusion method, the procedure was tested. Verification of the mathematical model has shown a high level of its adequacy, and it can be used in assessing the plasticity of pre-deformed billet.

Authors: Semenov Andriy , Baraban Serhii , Semenova Olena , Voznyak Oleksandr , Vydmysh Andrii , Yaroshenko Leonid
Published: May 2019

The method of non-destructive control of the molecular structure of solid materials is improved, the distinguishing feature of which is a new sign of suitability for the peak values of the thermodynamic process in solid materials, which made it possible to increase the reliability of the non-destructive control. A statistical norm for deciding on the suitability of solid materials was introduced, which made it possible to organize statistical express control of solid materials under conditions of industrial production of electronic devices. In the practical plan, a structural scheme and an algorithm for measuring control of the peak values of the differential-thermal analysis of solid materials are proposed, on the basis of which a microprocessor based device for statistical express control is developed.
Influence of Overheating and Cooling Rate on the Structure and Physicochemical Properties of Al-Cu Alloys
Authors: Filonenko Nataliia , Babachenko Oleksandr , Bartashevska Ludmila , Kononenko Ganna , Ivanov Nikita
Published: May 2019

The effect of overheating of the melt and cooling rate of alloys of the Al-Cu system with a copper content of 25.0 – 36.0% ( mass.), the rest of the aluminum is investigated. It is shown that an overheating of the liquid at 50 – 100 K above the liquid-liquid line leads to the formation of a fine-dispersed eutectic structure and the inhibition of the formation of primary aluminum crystals in the pre-evacuation of alloys and the Al2Cu phase in hypereuvtectic alloys, in accordance. An increase in the melt overheating temperature by 150 K above the liquid-liquid line and the subsequent cooling at 103 – 104 K/s leads to the complete inhibition of the formation of primary crystals. An overheating of the melt on 100 – 150 K alloys above the liquid line and subsequent cooling with a velocity of 103 – 104 K /s reduces the rate of corrosion by 30 – 45% and increases the numerical value in 1.3 – 1.45 times the relative wear resistance, and the brittleness of alloys decreases in 1.2 – 1.35 times in comparison with the samples after casting.
Passive Stiffness and Maximal and Explosive Strength Responses After an Acute Bout of Constant-Tension Stretching
Authors: Palmer Ty B. , Thiele Ryan M.
Published: May 2019

Context

Constant-tension (CT) stretching has been used to reduce hamstrings passive stiffness; however, the time course of hamstrings stiffness responses during a short bout of this type of stretching and the effects on maximal and explosive strength remain unclear.

Objective

To examine the time course of hamstrings passive-stiffness responses during a short, practical bout of manual straight-legged–raise (SLR) CT passive stretches and their effects on maximal and explosive strength in healthy young women.

Design

Descriptive laboratory study.

Setting

Research laboratory.

Patients or Other Participants

Eleven healthy women (age = 24 ± 4 years, height = 167 ± 4 cm, mass = 65 ± 8 kg) participated.

Intervention(s)

Participants underwent four 15-second SLR CT passive stretches of the hamstrings.

Main Outcome Measurement(s)

Hamstrings passive stiffness was calculated from the slopes of the initial (phase 1) and final (phase 2) portions of the angle-torque curves generated before and after the stretching intervention and at the beginning of each 15-second stretch. Hamstrings peak torque and rate of torque development were derived from maximal voluntary isometric contractions performed before and after the stretching intervention.

Results

The slope coefficients (collapsed across phase) for the third and fourth stretches and the poststretching assessment were lower than the prestretching assessment (P range = .004–.04), but they were not different from each other (P > .99). In addition, no differences in peak torque (t10 = −0.375, P = .72) or rate of torque development (t10 = −0.423, P = .68) were observed between prestretching and poststretching.

Conclusions

A short bout of SLR CT passive stretching may effectively reduce hamstrings stiffness without negatively influencing maximal and explosive strength.
Definition of fractional Laplacian for functions with polynomial growth
Authors: Dipierro Serena , Savin Ovidiu , Valdinoci Enrico
Published: May 2019

We introduce a notion of fractional Laplacian for functions which grow more than linearly at infinity. In such case, the operator is not defined in the classical sense: nevertheless, we can give an ad-hoc definition, which (in addition to the various results that we prove here) can also be useful for applications in various fields, such as blowup and free boundary problems.

In this setting, when the solution has a polynomial growth at infinity, the right hand side of the equation is not just a function, but an equivalence class of functions modulo polynomials of a fixed order.

We also give a sharp version of the Schauder estimates in this framework, in which the full smooth H¨older norm of the solution is controlled in terms of the seminorm of the forcing term.

Though the method presented is very general and potentially works for general nonlocal operators, for clarity and concreteness we focus here on the case of the fractional Laplacian.

Complying with Australia's illegal logging laws: tough reality after a soft start? Lessons from the United States and the European Union
Authors: Garcia Beatriz , Verschuuren Jonathan
Published: May 2019

Australia's new illegal logging laws aim at prohibiting the import of illegally harvested forest products from around the world. Soon after adoption, and following an intense debate on the expected costs of compliance, the legislation was reviewed and the proposed amendments finally disallowed. As of 2018 stricter enforcement actions were announced. This article identifies compliance issues observed in Australia and proposes ways to tackle them based on experiences in the United States and the European Union. We find that law enforcement helps shape market behaviour and reinforces compliance. A national legality assurance system, established in the supplier country, is an effective way to ensure legality verification, to alleviate the burden on individual businesses to prove legality, and to support the regulated community to comply with the law.

Authors: Hendon Tori , Hainline Mark S. , Burris Scott , Ulmer Jonathan D. , Ritz Rudy A.
Published: May 2019

The profession of agricultural education is experiencing shortages across the nation. Texas is critically impacted due to the renewed emphasis of career and technical education. This leads to questions about the preparedness of recent college graduates to handle the demands placed upon agricultural educators. Starting in 2012, Texas Tech University restructured the courses within the Department of Agricultural Education and Communications to better prepare graduates. The purpose of this study was to evaluate the agricultural education program at Texas Tech University by examining the preparedness of student teachers as determined by the cooperating teachers. A survey containing the characteristics of effective agricultural teachers identified by Roberts and Dyer (2004) was administered to cooperating teachers of Texas Tech University student teachers. The cooperating teachers evaluated the importance of the characteristics and the preparedness of Texas Tech University student teachers. The results of this survey were analyzed using a Borich needs assessment model. Texas Tech University cooperating teachers perceived student teachers to be most prepared in the categories of personal qualities and community relations and found the student teachers need further development of skills related to the categories of Supervised Agricultural Experience (SAE) and program planning/management.
Identifying the Agricultural Mechanics Knowledge and Skills Needed by Iowa School-based Agricultural Education Teachers
Authors: Hainline Mark S. , Wells Trent
Published: May 2019

A historical portion of many school-based agricultural education (SBAE) programs, agricultural mechanics remains popular in schools across the nation. As such, pre-service and in-service teachers should be prepared to effectively deliver agricultural mechanics instruction (Burris, Robinson, & Terry, 2005). Agricultural education researchers (McKim & Saucier, 2012; Pate, Warnick, & Meyers, 2012) have identified many laboratory management competencies and welding skills that teachers should have; however, few knowledge and skill areas in other components of agricultural mechanics (e.g., woodworking, electricity, etc.) have been identified. Through the lens of Roberts and Ball’s (2009) content-based model for teaching agriculture, we used the Delphi technique to identify the agricultural mechanics knowledge and skills that Iowa SBAE teachers should possess to provide quality instruction. A panel of 10 expert Iowa SBAE teachers provided the data for the present study. After three rounds, a total of 85 items reached consensus, which included 35 technical skills (e.g., plasma cutting, etc.) and 49 “teacher skills”/laboratory management skills (e.g., ordering consumables). We concluded that SBAE stakeholders in Iowa should ensure that teachers are prepared to teach agricultural mechanics via coursework and professional development opportunities. We recommend that this study be replicated in other states.
Competition as an Instructional Approach in School-Based, Agricultural Education (SBAE): A Historical Review
Authors: Jones Mason C. , Edwards M. Craig
Published: May 2019

The purpose of this study was to examine and describe the historical role of competition as an instructional approach in SBAE. Pragmatism was found to be the philosophical underpinning of competition in SBAE, and the influences of William James and John Dewey were described. The growth of new National FFA contests was presaged by seminal legislative acts such as the Smith-Hughes Act of 1917, the Vocational Education Act of 1963, and by educational reforms in the 1980s. We also identified and discussed the challenges associated with using competition as an instructional approach. Based on the profession’s longstanding concerns about competition at the expense of instruction, i.e., prizing winning over learning, it was recommended that SBAE’s stakeholders continue to examine the educational merits of its competitive activities to revise, alleviate, or add such as may be needed.
Teachers' Confidence to Integrate Biology in Agriscience Courses
Authors: Chumbley Steven "Boot" , Hainline Mark S. , Russell Mark , Ruppert David E.
Published: May 2019

The primary purpose of this study was to determine the confidence levels of School-based Agricultural Education (SBAE) teachers to integrate biology concepts in plant and animal science courses. The researchers also sought to describe the demographic characteristics of New Mexico SBAE teachers. This study used a descriptive-correlational research design. Teachers were asked to identify their confidence levels to teach the state standards of the animal science and plant science course that matched course objectives in biology and life science. The teachers had an average age of 39 and reported having an average of 13 years of teaching experience. The majority of New Mexico SBAE teachers received secondary science teacher certification and over 70% had obtained a master’s degree. Teachers felt the least confident to teach the processes of cell division, including binary fission, mitosis, and meiosis. Teachers felt the most confident integrating biology concepts within lessons dealing with the nutrients required by plants, how they obtain and transport those nutrients, as well as teaching the evolution of plants from green algae. The findings suggest that there are some relationships between years of teaching experience, school size, and teachers receiving the science certification.
Evaluating Interdisciplinary Teaching: Curriculum for Agricultural Science Education
Authors: Pauley Catlin M. , McKim Aaron J. , Curry Jr. Kevin W. , McKendree R. Bud , Sorenson Tyson J.
Published: May 2019

Interdisciplinary learning experiences (i.e., experiences which illuminate learning of, and connections among, multiple disciplines) are essential to building a more robust understanding of the interconnections of multiple systems. Having an interdisciplinary understanding positively influences the ability of learners to contribute to solving wicked problems (e.g., soil degradation, climate change), most of which fall within the realm of agriculture, food, and natural resources (AFNR). Therefore, within AFNR Education, preparing learners via interdisciplinary experiences could empower the next generation of problem solvers. The Curriculum for Agricultural Science Education (CASE) has emerged as a potential method for teaching AFNR and science in an interdisciplinary way. However, research has yet to evaluate the impact of CASE on teachers’ intentions to teach science within curricula. In this study, intentions to teach science were compared between CASE-certified and non-CASE-certified educators via a national survey of 212 randomly sampled teachers, 81 of whom were CASE-certified. Within four of the eight courses evaluated, CASE-certified teachers intended to teach more science than non-CASE-certified teachers, while non-CASE-certified teachers intended to teach more science in the remaining four courses. The findings suggest opportunities to enhance the interdisciplinary structure of CASE curriculum and/or explore alternative models for facilitating interdisciplinary learning within AFNR Education.
A Python framework for efficient use of pre-computed Green's functions in seismological and other physical forward and inverse source problems
Authors: Heimann Sebastian , Vasyura-Bathke Hannes , Sudhaus Henriette , Isken Marius Paul , Kriegerowski Marius , Steinberg Andreas , Dahm Torsten
Published: May 2019

Abstract. The finite physical source problem is usually studied with the concept of volume and time integrals over Green's functions (GF), representing delta-impulse solutions to the governing partial differential field equations. In seismology, the use of realistic Earth models requires the calculation of numerical or synthetic GFs, as analytical solutions are rarely available. The computation of such synthetic GFs is computationally and operationally demanding. As a consequence, on-the-fly re-calculation of synthetic GFs in each iteration of an optimisation is time-consuming and impractical. Therefore, pre-calculation and efficient storage of synthetic GFs on a dense grid of source to receiver combinations enables efficient look-up and utilisation of GFs in time critical scenarios. We present a Python-based framework and toolkit – Pyrocko-GF – that enables pre-calculation of synthetic GF stores, which are independent of their numerical calculation method and GF transfer function. The framework integrates a suite of established numerical forward-modelling codes in seismology, and can incorporate new user-specified GF calculation methods. Pyrocko-GF defines an extensible GF storage format suitable for a wide range of GF types, handling especially elasticity- and wave propagation problems. The framework assists with visualisations, quality control and exchange of GF stores, which is supported through an online platform that provides many pre-calculated GF stores for local, regional and global studies. The Pyrocko-GF toolkit comes with a well-documented application programming interface (API) for the Python programming language to efficiently facilitate forward modelling of geophysical processes, e.g. synthetic waveforms or static displacements for a wide range of source models.

David E. Dobbs produced a recursive construction for large sets of non-overlapping Klein 4-subgroups inside $\mathbb{Z}_2^n$.  We show that the construction can be used to build the maximum such sets.
Commutative group algebras and Prufer groups
Authors: Danchev P. V.
Published: May 2019

Suppose $G$ is a multiplicatively written abelian $p$-group, where $p$ is a prime, and $F$ is a field of arbitrary characteristic. The main results in this paper are that none of the Sylow $p$-group of all normalized units $S(FG)$ in the group ring $FG$ and its quotient group $S(FG)/G$ cannot be Prufer groups. This contrasts a classical conjecture for which $S(FG)/G$ is a direct factor of a direct sum of generalized Prufer groups whenever $F$ is a perfect field of characteristic $p$.

Authors: Murugesu R. , Suguna S.
Published: May 2019

In this paper, by using fractional power of operators and Sadovskii's fixed point theorem, we study the existence of mild and strong solutions of nonlinear neutral functional integrodifferential equations. The results we obtained are a generalization and continuation of the recent results on this issue.
Blenders for a non-normally Henon-like family
Authors: Kiriki Shin , Nakajima Masaki
Published: May 2019

A blender is an indispensable concept presented by Bonatti and Diaz [3] to study high-dimensional $C^1$-robust transitive dynamics around heterodimensional cycles. In this paper, we present a certain Henon-like family of real quadratic diffeomorphisms on $\mathbb{R}^3$, which exhibits an phase transition from non-normal horseshoes to blenders. It can be observable from a rapidly jump of topological dimension for some projected stable segments in some characteristic region of $\mathbb{R}^3$.

On purity and related universal properties of extensions of commutative rings
Authors: Dobbs David E
Published: May 2019

Let $R \subseteq S$ be a unital extension of commutative rings. Then $R$ is a pure $R$-submodule of $S$ if and only if, for each finite set of algebraically independent indeterminates $\{X_1, \, \dots \,,X_n\}$ over $S$ and each ideal $I$ of $R[X_1, \, \dots \,,X_n]$, one has $IS[X_1, \, \dots \,,X_n] \cap R[X_1, \, \dots \,,X_n]=I$. Suppose also that $R$ is a Pr\"ufer domain. Then $R$ is a pure $R$-submodule of $S$ if and only if, for each unital homomorphism of commutative rings $R \to T$, each chain of prime ideals of $T$ can be covered by a corresponding chain of prime ideals of $T \otimes_R S$.

Existence of solutions for high order ordinary differential equations with some periodic-type boundary condition
Authors: Jhuang S. C. , Lian W. C. , Wang S. P. , Wong F. H.
Published: May 2019

We consider the following high order periodic-type boundary value problem \[ \lefteqn{(PBVP)}  \left\{\begin{array}{lll}  (E)~u^{(n)}(t)= f(t,u(t),u^{(1)}(t), \cdots, u^{(n-2)}(t), u^{(n-1)}(t))~\mbox{for}~t\in (0,T) \\  (PBC)~\left\{\begin{array}{lll}  u^{(i)}(0)=0,~0\leq i\leq n-3,\\  u^{(n-2)}(0)= u^{(n-2)}(T),\\  u^{(n-1)}(0)= u^{(n-1)}(T),  \end{array}\right.  \end{array}\right. \] where $f\in C([0,T]\times\mathbb{R}^n,\mathbb{R})$, $n\geq 2$ and satisfies the so-called Nagumo's condition. In this article, we will use a general upper and lower solution method to establish an existence theorem for solutions of $(PBVP)$.
Weakly unique factorization modules
Authors: Oral Kursat Hakan , Tekir Unsal , Agargun Ahmet Goksel
Published: May 2019

In this work we give the definition of weakly prime element of a module. Therefore we give a new definition of factorization in a module, which is called weakly factorization. So we call a module weakly unique factorization module if all elements have a weakly factorization which is unique. We give the relation between weakly prime elements and weakly prime submodules. Then we characterize such weakly unique factorization modules.

On the multiplicity of the eigenvalues of the vectorial Sturm-Liouville equation
Authors: Lin Chien-Wen
Published: May 2019

Let $ Q(x) $ be a continuous $ m\times m $ real symmetric matrix-valued function defined on $ [0,1] $, and denote the Sturm-Liouville operator $ -\frac{d^2}{dx^2}+Q(x) $ as $ L_Q $ with $ Q(x)$ as its potential function. In this paper we prove that for each Dirichlet eigenvalue $ \lambda_* $ of $L_Q$, the geometric multiplicity of $ \lambda_* $ is equal to its algebraic multiplicity. Applying this result, we get a necessary and sufficiently condition such that each Dirichlet eigenvalue of $ L_Q $ is of multiplicity $ m $.
Reconstruction of the Sturm-Liouville operators on a graph with $\delta'_s$ couplings
Authors: Yang ChuanFu
Published: May 2019

Inverse nodal problems consist in constructing operators from the given zeros of their eigenfunctions. In this work, we deal with the inverse nodal problems of reconstructing the Sturm- Liouville operator on a star graph with $\delta'_s $ couplings at the central vertex. The uniqueness theorem is proved and a constructive procedure for the solution is provided from a dense subset of zeros of the eigenfunctions for the problem as a data.

Authors: Buterin Sergey
Published: May 2019

A second-order differential pencil on a finite interval with spectral parameter dependent boundary conditions is considered. The inverse problem is studied of recovering the coefficients of the boundary value problem from its spectrum, provided that on one half of the interval they are known a priori. The uniqueness theorem for this inverse problem is proved and a constructive procedure for finding its solution is obtained.

Long-Term Performance Implications of Management Innovation
Authors: Bezdrob Muamer
Published: May 2019

Any kind of innovative activity is driven by the urge for utmost success, continuous improvement or mere survival. The same holds true for management innovation, arguably the most advanced innovation type in the world of business. Although previously unjustifiably neglected, a significant number of studies have emerged recently that prove the potency of this type of innovation. Following such a trend, this study explores another distinguishing feature of management innovation - its durability. The study findings confirm the claim that companies that are innovative in management achieve better business performance in the long run. In addition, the study provides further support for the new direction in researching the innovation concept - an interdependent or synchronous approach to the adoption of different types of innovation on the company level.
Determinants of early stage high-growth entrepreneurship: Evidence from South East Europe region
Authors: Leković Bojan , Berber Nemanja
Published: May 2019

The main objective of this paper is to determine the factors of influence on growth aspired entrepreneurial ventures in order to determine characteristics of these entrepreneurs in the SEE region. We draw upon data from the Global Entrepreneurship Monitor international survey in order to provide deeper insight into the high-growth entrepreneurship in selected SEE countries. For the purposes of this research, the authors included six countries in the research sample of South East Europe: Slovenia, Croatia, Hungary, Romania, Bosnia and Herzegovina, and FYR of Macedonia. An exploratory sample of the mentioned countries was 12027 respondents and 457 high-growth entrepreneurs. Based on the nature of the observed variables, we used Spearman's correlation and ordinal logistic regression (ORL) in order to explore the relations between variables. We used OLR to explore the relation between the national culture, entrepreneurial motives, and aspiration to the level of entrepreneurial growth intentions. The findings demonstrate that entrepreneurial motives, innovation, and internationalization of new business venture have statistically significant relations with the high-growth aspirations among entrepreneurs in South East Europe region.
Sprachgrenzen
Authors: Stepec Katja
Published: May 2019

Eine Übersetzung funktioniert, weil Ausdrücke in unterschiedlichen Sprachen dieselbe Bedeutung haben – so die alltagspraktische Intuition. Dahinter verbirgt sich ein atomistisches Verständnis von Bedeutung, das von den sprachphilosophischen Reflexionen des semantischen Holismus überzeugend in Frage gestellt wird. Ihnen zufolge kann Bedeutungsgleichheit nicht durch Referenz auf ein außersprachlich Gegebenes garantiert und damit einfach vorausgesetzt werden.

Dann aber drohen sprachlicher Relativismus und semantische Inkommensurabilität, was gemeinhin Unübersetzbarkeit zur Folge hätte. Wie kann trotzdem erklärt werden, dass Übersetzen möglich ist?

Die vorliegende Studie beantwortet diese Frage, indem sie anhand der Ansätze von W.V. Quine, Donald Davidson und Robert Brandom zunächst den Mangel des semantischen Holismus herausarbeitet, der Bedeutung grundsätzlich intrasprachlich fasst. In der Folge wird Übersetzung als Interpretation missverstanden.

Stattdessen soll Übersetzen als normativer intersprachlicher Vergleich konzipiert werden, sodass sich Bedeutungsgleichheit nicht als Voraussetzung, sondern als Ergebnis des Übersetzens darstellt. Eine Erklärung des Übersetzens ist insofern nicht nur möglich, sondern erweist sich auch als notwendig, um die Erklärungsdefizite des semantischen Holismus zu überwinden.
Begehren nach Lacan und über Lacan hinaus
Authors: Bossinade Johanna
Published: May 2019

Begehren ist immer das Begehren des Anderen. Damit wird der Abstand, der zwischen dem Subjekt und dem Anderen klafft, virulent. Wer das Begehren verstehen will, muss diesem sich öffnenden Feld der Kluft, der »béance fondamentale«, wie Jacques Lacan es nennt, verstärkt Aufmerksamkeit widmen. Nicht umsonst hat der französische Psychoanalytiker es ins Zentrum des Unbewussten gerückt.

Die vorliegende Studie hat zum Ziel, Lacans Konzept nicht nur nachzuvollziehen, sondern es zu einer vielseitig verzweigten allegorischen Umschrift zu erweitern. So kann auch dem nachgespürt werden, was Objekt des Begehrens genannt wird. Lacans Entwurf einer ursächlichen Objektwirkung, die das Subjekt der sogartigen Präsenz des Anderen aussetzt, ist dabei von entscheidender Relevanz.

Die Autorin kreist Schlüsselbegriffe Lacans aus verschiedenen Werkphasen ein und rezipiert die aktuellen Debatten dazu. Sie erläutert Lacans gedanklichen Ansatz, erweitert ihn jedoch um neue Ideen und methodische Zugänge, unter anderem anknüpfend an Überlegungen Derridas. So wird es auch möglich, dem Verfahren der psychoanalytischen Deutung mehr Freiraum zu geben, speziell mit Blick auf die Geschlechtertheorie und den Aspekt des Anderen.
