Bildung und Intralogistik in der Industrie 4.0 – eine empirische Annäherung
Authors: Pfeiffer Sabine 
Published: December 2016

ZusammenfassungDer digitale Wandel trifft auch Tätigkeiten, über die aktuell wenig empirisch Konkretes bekannt ist. So verändert Industrie 4.0 auf Logistik bezogene Tätigkeiten innerhalb produzierender Unternehmen. Der Artikel prüft auf Basis von Daten der BIBB/BAuA-Erwerbstätigenbefragung, wie diese Beschäftigtengruppe erfasst werden kann, und stellt Ergebnisse zu Qualifikation, Routine-Anteilen und IT-Nutzung vor. Dabei zeigt sich, dass die Beschäftigten in der produktionsnahen Intralogistik qualifizierter sind als oft angenommen und bereits heute vielfältig mit Digitalisierung am Arbeitsplatz konfrontiert sind. Zudem findet sich ein hoher Anteil an Nicht-Routine – gefasst als Umgang mit Wandel, Komplexität und Unwägbarkeiten.
Using in vitro methods to estimate metabolizable energy content of five forage legumes harvested under different defoliation systems / Einsatz von in vitro Methoden zur Schätzung der umsetzbaren Energie in fünf Futterleguminosen aus unterschiedlichen Nutzungssystemen
Authors: Gierus Martin , Eickler Birgit , Resch Reinhard , Loges Ralf , Taube Friedhelm , Poetsch Erich M. 
Published: December 2016

Summary
Two in vitro methods were tested to establish their potential to predict the metabolizable energy (ME) content of forage legumes: the Tilley and Terry (TT) method and the pepsin-cellulase method (CM). Different samples of white clover (Trifolium repens L.), red clover (Trifolium pratense L.), kura clover (Trifolium ambiguum M. Bieb.), lucerne (Medicago sativa L.), and birdsfoot trefoil (Lotus corniculatus L.) were derived from field trials with several defoliation systems at two sites. The CM was more precise due to its repeatability within and between analysis runs, but eventually overestimated the ME contents of the samples, as it was shown for the standard samples with known in vivo digestibility. ME contents were found to be consistently higher based on CM, with a difference of up to 1.5 MJ ME/kg DM compared to TT. Although white clover was, in general, the species with the highest ME content, the influence of legume species over all cuts and defoliation systems was inconsistent. Such observations may influence the method of choice for ME estimation for large datasets.
Cellobiose dehydrogenase: An essential enzyme for lignocellulose degradation in nature – A review / Cellobiosedehydrogenase: Ein essentielles Enzym für den Lignozelluloseabbau in der Natur – Eine Übersicht
Authors: Kracher Daniel , Ludwig Roland 
Published: December 2016

Summary
The flavin and heme cofactor containing enzyme cellobiose dehydrogenase (CDH) is ubiquitously distributed in wood-degrading fungi. Current research provides compelling evidence that CDH is an activator for cellulolytic monooxygenases, which enhance the accessibility of crystalline cellulose surfaces for hydrolases. Such oxidative cellulose degradation contributes to the overall cellulolytic capabilities of wood decaying fungi to a large extent, and holds great potential to improve the efficiency of commercial enzyme mixtures for biomass processing and biofuel production. This review summarizes current literature with regard to the distribution, structure and physiological role of CDH in the light of recent findings.
Thermal use of wastewater – Policy instruments for initialization and potential operating models / Thermische Nutzung von Abwasser – Instrumente zur Verbreitung und mögliche Betreibermodelle
Authors: Kretschmer Florian 
Published: December 2016

Summary
The heat content of wastewater presents a great but still widely unused potential for energy supply. The thermal energy recovered through heat exchangers and heat pumps can be used for the heating (and cooling) of buildings and even for hot water production. At the moment, at least about 500 installations are operated on a global scale, and most experiences are available in Switzerland. In Austria, some wastewater heat recovery systems are also already under operation, for instance in Amstetten and in Weiz. However, due to the lack of superordinate strategies for planning, implementing, and operating wastewater heat recovery systems on federal and provincial level, the Austrian installations are primarily the result of personal initiatives of local stakeholders. This paper gives a general overview of different policy instruments for initializing and further promoting wastewater heat recovery as well as potential operating models for related heat supply systems and conducts a related comparison with the current Austrian situation. The information gained can serve as an input for the development of an initialization program for wastewater heat recovery on Austrian national level.
The role of the Rogers–Shephard inequality in the characterization of the difference body

Published: December 2016

Abstract
The Rogers–Shephard and Brunn–Minkowski inequalities provide upper and lower bounds for the volume of the difference body in terms of the volume of the body itself.

Linearized Implicit Numerical Method for Burgers’ Equation
Authors: Mukundan Vijitha , Awasthi Ashish 
Published: December 2016

AbstractIn this work, a novel numerical scheme based on method of lines (MOL) is proposed to solve the nonlinear time dependent Burgers’ equation. The Burgers’ equation is semi discretized in spatial direction by using MOL to yield system of nonlinear ordinary differential equations in time. The resulting system of nonlinear differential equations is integrated by an implicit finite difference method. We have not used Cole-Hopf transformation which gives less accurate solution for very small values of kinematic viscosity. Also, we have not considered nonlinear solvers that are computationally costlier and take more running time.In the proposed scheme nonlinearity is tackled by Taylor series and the use of fully discretized scheme is easy and practical. The proposed method is unconditionally stable in the linear sense. Furthermore, efficiency of the proposed scheme is demonstrated using three test problems.

An Empirical Study of the Relationship between Entrepreneurial Competences and Innovativeness of Successors in Family SMEs
Authors: Letonja Marina , Jeraj Mitja , Marič Miha 
Published: December 2016

Abstract

Background and Purpose: In the recent period, scholarly interest for family entrepreneurship and succession has been increasing while the question of innovative capability of family SMEs and of innovativeness of founders and successors is relatively unexplored. Little is known about the factors, which are positively correlated, or affect innovativeness of successors in family SMEs. This research explores the relationship between entrepreneurial competences of the founders in family SMEs and innovativeness of their successors.

Design/Methodology/Approach: The target group were family SMEs of the first and the second generation – their founders and successors in Slovenia. As our research includes two independent samples with mostly ordinal data, we used univariate (analysis of means, variance, reliability index Cronbach alpha, t-test) and multivariate (simultaneous analysis of more variables, correlation) statistical methods to study the two constructs - entrepreneurial competences of the founders and innovativeness of successors, to test the positive correlation between the two.

Results: Results indicate that entrepreneurial competences like creativity, attitude toward risk-taking, attitude toward negotiations, technical knowledge and skills and marketing knowledge and skills of the founders in family SMEs positively correlate with innovativeness of successors. The results of this study indicate that entrepreneurial competences of founders are important factor for fostering innovativeness of successors.

Conclusion: This paper links the two studied constructs and presents a valuable contribution for entrepreneurship theory; therefore, the results could be used for a further scientific research as also for practical implications.

Authors: Arnejčič Beno 
Published: December 2016

Abstract

Background and purpose: The individual is exposed to ever more covert psychological violence or mobbing in workplace within companies. The aim of this study is to analyse the level and the types of psychological violence within a company in which the individual works in their daily lives.

Design/Methodology/Approach: Using systematic method current mobbing literature reviews were analysed. Based on a review and analysis of the literature, we recognised increasing amounts of workplace bullying. Then we used and extended Dilts’ model and created a model in which we portrayed the different levels and types of bullying in a company. The presented model is a tool for identifying workplace violence within the company.

Results: At the company environment level, there is much bullying associated with social-demographic characteristics and working conditions. At the level of individual behaviour, the type of mobbing exists that is associated with the company’s leadership styles. At the level of professional qualifications, a lack of confidence causes mobbing. At the level of values and beliefs, mobbing is present in attitudes and behavioural intentions. At the level of identity, we can observe mobbing according to sexual identity. At the level of organizational culture, we can recognize a type of mobbing called ‘obsessive dedication’ to working efficiency and organizational silence.

Conclusion: Based on the analysis of selected literature we exposed a range of types and levels of mobbing in company. The expanded Model on levels of mobbing in companies provides a framework for collecting information. The user can identify workplace violence and each strategic organizational level in the work organization
Does Sport Event Involvement Influence Brand Recognition of Official Sponsors and Ambush Marketers?
Authors: Piątkowska Monika , Gocłowska Sylwia 
Published: December 2016

Abstract
The main aim of the study is to verify how event involvement in the UEFA Euro 2012 influenced the recognition of both sponsors’ and ambushers’ brands. Computer-Assisted Personal Interviews were conducted on a representative sample of the Polish society (N = 1,000). On the basis of five groups of consumers regarding involvement in the event, authors examined brand recognition, using Top of Mind Awareness (TOMA) tests of official sponsors and ambushers.
The highest TOMA rate was observed in the group of heavy viewers. The lower the quantity and intensity of the matches watched, the lower the percentage of people who recalled a brand of the official sponsor at first. An inverse relationship exists in the case of people who identified the ambush marketers.
Ambush marketing phenomenon does not seem to threaten official sponsors of the event among consumers involved in the event. Therefore, it seems to be crucial to take into account the division between fans and non- fans of the event and level of their event involvement whilst measuring brand recognition.
It is noticeable that in the current literature the issue of effects of ambushing on consumers divided into groups of fans and non-fans has been largely ignored. Thus this study shows how important conducting a test of brand recognisability based on involvement of consumers in the sport event is.
Efficiency of Governmental Funding in Hungary
Authors: Gulyás Erika , Sterbenz Tamás , Kovacs Eszter 
Published: December 2016

AbstractThis paper presents the initial results of a significant research project conducted under the IOC PhD Student Research Grant Program with the support of the Hungarian Olympic Committee. Macro- and meso-level analyses were conducted within the framework of this research to analyze the competitive position of the Hungarian elite sport policy system. In the following, an essential part of the research will be presented with the aim of modeling the efficiency of the Hungarian sport funding system as the increasingly international sporting competition forces governments to invest more money in elite sport development just so they can maintain their elite sport success as the supply of medals remains basically constant. Due to these diminishing returns to the scale of investment, an elite sporting system with an efficient structure will be key in future sporting success. Data collection was based on information gained through a general questionnaire and interviews with the main stakeholders of national sport federations and the Hungarian Olympic Committee, which is the main governing body of Hungarian high-performance sport. Data collection focused on the sixteen prioritized sport federations and the five team sports that benefited from a tax relief system. Secondary data were collected regarding the national public funding for sport, elite sport, and sport by sport since 2006, and Gracenote’s database was used to analyze historical performance in the different disciplines and compare Hungarian performance with that of other countries. This research will provide information to policy makers about the competitive position of Hungary in elite sport and, in this respect, explore the critical success factors that will allow Hungary to assess how best to manage its future success in an increasingly competitive international environment.

Regional Particularities of the Metonic Meteorological Cycle on Earth
Authors: Isaia Ion 
Published: December 2016

Abstract
This paper intends to demonstrate that, on Terra's surface, there are cycles of air's temperature and of other meteorological elements having a duration of 19 years (the Metonic cycle). These 19-year cycles are recorded on every continent, especially in temperate climate areas where the (planetary) Rossby waves exhibit very clearly. As in the case of other cycles of meteorological elements, the atmospheric tides play a very important role in their occurrence. In the case of this cycle, the atmospheric tides are also generated mainly by Moon’s and Sun’s attraction.

Published: December 2016

Abstract
Pollution negative influences the environmental, human health, buildings and increase the production of waste. We are currently witnessing pollution and degradation in some cases irreversible, of the environment. Environmental issues are extremely complex and cover all sectors. Worldwide, industrial pollution strategies necessary to reduce emissions to the atmosphere hydrocarbons, volatile organic compounds (VOCs) and other polluants in urban areas. The highest concentrations of volatile organic compounds of more than 80 mg/m3 occur in densely populated areas. The latest data reported in the residential area of Cluj-Napoca values did not exceed 20 m /m3. However peaks reported VOC concentrations, depending on the season, exceeding the upper limit that according to Law. 104/2011 is 75 μ/m3. It was identified due to increase annual mean concentration of VOCs as, in particular, road traffic exceeding sanitary standards on the main traffic routes within the city. In this paper the results obtained after carrying out an analysis of the average VOC concentration recorded in the city Cluj-Napoca as a result of car traffic. They were pursued average concentrations of VOCs resulting from the combustion of liquid fuels, petrol and diesel type. Analyzing the results obtained are proposed solutions for reducing VOC emissions. The rule under which these solutions have been proposed to reduce the concentration of VOCs took into account the possibility implementation and maintenance costs thereof.
Scleromyxedema (Arndt-Gottron Syndrome): a Case Report
Authors: Popović Danijela , Paravina Mirjana , Jovanović Dragan , Karanikolić Vesna , Ljubisavljević Dragana 
Published: December 2016

Abstract
Lichen myxedematosus, also known as papular mucinosis, is a primary diffuse cutaneous mucinosis. It is a rare cutaneous myxedematous condition characterized by formation of numerous lichenoid papules. Scleromyxedema, also known as Arndt–Gottron syndrome, is a rare, confluent, papular and sclerotic variant of lichen myxedematosus, characterized by diffuse thickening of the skin underlying the papules. The condition is associated with systemic, even lethal manifestations, fibroblast proliferation and accumulation of acid mucopolysaccharides of the hyaluronic acid. Serum IgG class paraproteinemia is always present and it can be detected in all patients if appropriate or even repeat testing is used.
Herein, we present a 67-year-old patient with a 2-year history of skin problems. He had no health problems other than hypertension and diabetes, wich were both diagnosed 15 years before. On examination, the patient exhibited sclerodermoid lesions with diffuse pseudo-sclerodermatous thickening of the exposed skin, microstomia and sclerodactyly-like changes; on the face, there were numerous solid, shiny 2 - 4 mm in diameter skin-coloured lichenoid papules, scattered across the forehead, glabellar area, nasolabial folds, perioral region, ear lobes and the neck. Histopathological examination revealed: highly distinctive collagenosis and fibrosis in the middle dermis, increased fibroblasts; collagen bundles with irregular arrangement and fragmentation; alcian blue-positive deposits with appearance consistent with acid mucins. Serum protein electrophoresis detected IgG lambda paraproteinemia. The patient was treated with systematic corticosteroids during 9 months with subsequent introduction of methotrexate and showed satisfactory results.
The etiology of scleromyxedema remains unknown, since the purified IgG paraprotein itself has no direct effects on fibroblast proliferation. In scleromyxedema, numerous therapeutic modalities are proposed, unfortunatelly with limited effects.
In colclusion, we report a case of an adult male with lichenoid papules; after a two-year progression, they evolved into scleromyxedema and exhibited well response to conventional therapy.
