Die Ökonomie ist eine Wissenschaft mit sehr vielen Schulen, die unterschiedliche Lehrmeinungen vertreten. Die vielen Schulen und Lehrmeinungen sind nicht förderlich für die erfolgreiche Beratung der Politik durch die Ökonomie. Die Ökonomie kann vor allem keine optimale Beratung leisten, wenn sie sehr stark von einer anspruchsvollen Mathematik geprägt ist. Die Ratsuchenden verstehen die Ratschläge nicht und akzeptieren sie daher nicht. Es kommt folglich auch nicht zur Umsetzung der Ratschläge. Aus diesem Grund wird hier ein neuer, einfacher Ansatz der Ökonomie vorgestellt, für dessen Verständnis nicht mehr mathematische Kenntnisse erforderlich sind, als für das Arbeiten mit dem betrieblichen Rechnungswesen.

„Mathe – kann ich“ – ein Satz, den die Mehrheit der Studierenden zu Beginn eines ingenieurwissenschaftlichen Studiengangs sicher nicht mit sich in Verbindung bringt. Die Buchreihe „Mathe – kann ich“ zielt darauf ab, dies schnell und einfach zu ändern. Der erste Band der Reihe befasst sich mit Grundlagenstoff. Er umfasst 14 Kapitel, von Arithmetik, Algebra, Polynome, Funktionen, Folgen über Ableitung und Integrationsrechnung bis hin zu Beweisen und Mengen. Jedes Kapitel führt in das Thema kurz ein, die verwendeten Begriffe werden definiert. Viele einfache Abbildungen tragen zur Veranschaulichung bei. Ausformulierte Lernziele, die jeweils mit „Ich kann …“ beginnen, helfen, sich die benötigte Mathematik zu erschließen. Sie folgen dem aktuell gültigem Curriculum der Europäischen Gesellschaft für die Ingenieur-Ausbildung (SEFI). Jedes Kapitel bietet zusätzlich eine Vielzahl an Aufgaben und schließlich ausführlichen Lösungen. Zu jeder Aufgabe gibt es eine Zeitangabe, die den Studierenden bei der Auswahl zum Anfang hilft. Die Aufgaben selbst sind unterschiedlich, teils auf Anwendung bezogen, teils zum Rechnen, teils zur Klärung der Begrifflichkeiten. Das Arbeiten mit Kann-Listen macht den eigenen Lernerfolg für Studierende sichtbar: einfach Abhaken! Darüber hinaus verbindet es das zu Lernende mit der Meta-Ebene des Stoffs, was für nachhaltiges Erinnern entscheidend ist. Der innovative didaktische Ansatz hat sich in der Praxis bewährt. Zusatzmaterialien zum Buch, wie computerunterstützte Lösungen zu den Aufgaben oder einige der Visualisierungen, werden auf plus.hanser-fachbuch.de bereitgestellt.

Visitors to events attach great importance to the range of artists and their performances and the quality of their stay and services. To create a staging and, consequently, an emotionalization of the visitor, many action areas simultaneously take effect at an event. In this context, the customer satisfaction of visitors plays a major role for event organizers, which aims to generate a competitive advantage over other providers and be attractive for artists simultaneously. This article aims to analyse the perceived functional quality of service (QoS) during various events in a multi-purpose event venue. The analysis was based on 563 primary data samples. On the off chance, selected visitors were during the events recruited and interviewed using a standardized questionnaire. The data were collected during the break of five events. These events took place in the period from mid-November to mid-December 2019. This was supplemented by an online survey of enthusiastic fan club visitors who regularly watch handball matches within the event venue. The online survey was conducted in parallel with the surveys during November 2019. Overall, the results showed a high level of satisfaction among visitors regarding the QoS. In addition to services, exploratory factor analysis identified cleanliness as a satisfaction factor that significantly accounted for overall service satisfaction. Differences in the perception of both factors could be detected between the fan club visitors on the one hand and all other visitors of various events (comedy, music, sports) on the other. Based upon the results of this analysis, the event managers of this venue are enabled to employ target group-oriented improvements of individual services to consolidate and increase customer satisfaction.

The way in which brands are economically represented in the context of financial reporting is controversial in theory and practice. This holds especially against the background of the ever- increasing importance of intangible assets. Brands and the economic success associated with them are thus regarded as a key variable for overall corporate success: cash flows can be accelerated and expanded through the use of brand-strategic options, while existing risks may be mitigated. In addition to a large number of theoretical definitions, the determination of brand value from both a marketing and an accounting perspective is also characterized by a complex interaction of numerous influencing factors. This is where the International Accounting Standards IAS 38: "Intangible Assets" (isolated acquisition of a brand) and IFRS 3: "Business Combinations" (acquisition of a brand as part of a business combination) take effect: These are intended to ensure a comparable and reliable "true and fair view" for the presentation of intangible assets in international accounting. In addition to various recognition criteria, the accounting regulation here also includes the accounting valuation of intangible assets and thus also of brands. In principle, valuation in accordance with IAS 38 is based on acquisition costs. The determination of the operating life for impact evaluation is highly controversial both in literature and in practice. Under IFRS 3, acquisition costs are to be replaced by the fair value. Regardless of the method used, possible subjectivity is one of the central issues. The current discussion approach of the International Accounting Standards Board also clearly shows the need for simplification and concretization that still exists for practice: In particular, the accounting distinction between goodwill and intangible assets is the subject of discussions with the Global Preparers Forum, among others. The interests of users, preparers and auditors of corporate financial reporting must be taken into account equally. In particular, the prohibition on recognizing self-created brands in the balance sheet makes it difficult to assess their value. Furthermore, it creates a weak point in the presentation of the true and fair view of a company's financial position and financial performance that is generally required. Regardless of the previous, the current rules provide preparers and users with a basic overview of existing intangible assets. Irrespective of how valuation is determined individually, the IASB's rules thus help to create a fundamental structure. In which approach the future discussion will result in remains open.

Die Vereinten Nationen propagieren seit der Veröffentlichung des Brundtland-Berichts im Jahr 1987 die Verwirklichung eines weltweiten nachhaltigen Entwicklungsprozesses. Zur Durchsetzung der drei Komponenten der Nachhaltigkeit, der sozialen, der ökologischen und der ökonomischen Nachhaltigkeit, hat sich eine intensive Forschungsaktivität entwickelt. Eine kleine Auswahl der Forschungserkenntnisse, die im Einflussbereich der Herausgeber der Schriftenreihe "Lingener Studien zu Management und Technik" im Jahr 2020 entstand, wird im vorliegenden Sammelband präsentiert. Die Forschungsergebnisse, deren Diskussion oft nur im Kreise der Wissenschaft erfolgt, wird somit der interessierten Öffentlichkeit zugängig gemacht. Dr. habil.

Vanadium carbide (VC) reinforced FeCrVC hardfacings have become important to improving the lifetime of tools suffering abrasive and impressive loads. This is because the microstructural properties of such hardfacings enable the primary VCs to act as obstacles against the penetrating abrasive. Because dilution is supposed to be the key issue influencing the precipitation behaviour of primary carbides during surfacing, the development of deposit welding processes exhibiting a reduced thermal impact, and hence lower dilution to the base material, is the primary focus of the current research. By inserting an additional hot wire in the melt, an approach was developed to separate the material and energy input during gas metal arc welding (GMAW) and hence realised low dilution claddings. The carbide content could be increased, and a grain refinement was observed compared with conventional GMAW. These effects could be attributed to both the reduced dilution and heterogeneous nucleation.

The accounting of small and medium enterprises is specific, compared to the accounting of large enterprises, for several reasons. First of all, lower business volume implies less demanding accounting in terms of less turnover and the number of accounts to be processed, lower financial reporting requirements, more favourable tax treatment is expected and the like. Practical experience in the years of application of EU-accounting directives, which represent the framework of financial reporting of companies at the EU level, pointed to certain difficulties or excessive administrative burden of small and medium enterprises in relation to the requirements for large companies and identified areas for improvement. The complexity of these regulations as well as problems in practical application have led to the need to develop and publish a revised single accounting directive (2013/34/EU). This Directive was primarily adopted with the aim of simplifying the accounting and financial reporting of small and medium-sized enterprises. Today, it is common for small and medium-sized enterprises to go beyond the borders of one country. In the internationalization of business, SMEs face many challenges and potential barriers. First of all, it refers to financial, human and procedural barriers, but also to informational barriers related to regulations, rules and laws of other countries. Since the accounting and tax treatment of the same business transaction may differ between countries, it seems entirely justified to investigate whether there are differences in the regulation and regulation of the accounting system between the two countries. This paper compares the characteristics of small and medium-sized enterprises’ accounting systems between two economically strongly connected countries, Germany and Croatia, which is the main goal of this paper. It is well known that financial reporting is a particularly important, final phase of accounting data processing. Namely, financial reporting system of these two countries is compared by using the method of comparison and classification analysis. The types and scope of financial statements have been defined and the content of financial statements that SMEs are obliged to compile and publish has been analysed. The paper pays additional attention to the analysis of similarities and differences between these two accounting regulations as well as current events in the implementation of the revised accounting directive into national legislation, especially in simplifying the financial reporting of the smallest, but numerically most represented micro enterprises. The important finding of the research show that some changes have been made but there is still room to improve accounting regulations for this segment of entrepreneurship.

Seitdem die Vereinten Nationen die Verwirklichung eines weltweiten nachhaltigen Entwicklungsprozesses propagiert haben, hat sich eine umfangreiche Nachhaltigkeitsforschung (Sustainability Research) herausgebildet. Es wird untersucht, wie die drei Komponenten der Nachhaltigkeit, die soziale, die ökologische und die ökonomische Nachhaltigkeit, umgesetzt werden können. Aus der Vielzahl der Forschungsbeiträge zum Thema Nachhaltigkeit wird im vorliegenden Band eine Auswahl präsentiert, die im Einflussbereich der Herausgeber der Schriftenreihe "Lingener Studien zu Management und Technik" bis zum Jahr 2019 entstand.
