Dieses Arbeitspapier beschäftigt sich mit der Revitalisierung von Shopping-Centern in Deutschland. Mit diesem Papier wird das zentrale Ziel verfolgt, zu analysieren, welche Aus-wirkungen ausgewählte, aktuelle Trends auf den Einzelhandel und auf Shopping-Center ha-ben. Des Weiteren wird untersucht, welche Maßnahmen im Zuge einer Revitalisierung nötig sind, damit Shopping-Center in Zukunft erfolgreich am Markt bestehen können, oder ob das Konzept dieser Asset-Klasse generell nicht mehr zukunftsfähig ist. In diesem Zusammenhang werden auch Erfolgsfaktoren, Chancen und Risiken analysiert, die speziell im Zusammenhang mit der Revitalisierung von Shopping-Centern relevant sind. Um eine fundierte Ausarbeitung der genannten Punkte liefern zu können, wurde eine empirische Studie in Kooperation mit dem German Council of Shopping Centers e.V. durchgeführt. Diese wird im Rahmen des Arbeits-papiers mit der Revitalisierungsstudie von Sturm (2006)1, der letzten empirischen Analyse zu diesem Thema für den deutschen Markt, verglichen.
Dieses Arbeitspapier beschäftigt sich mit Immobilien-Benchmarking. Zentrales Ziel der Schrift
ist es, einen Einblick in die bisherige Etablierung des Benchmarkings in den Managementebenen
der Immobilienwirtschaft zu gewinnen und die Eigenschaft der Heterogenität der Immobilien
im Benchmarking hervorzuheben. Dabei wird das Portfoliomanagement, das Asset Management,
das Property Management sowie das Facility Management in Bezug auf die Potenzialhebung
betrachtet. Weiterhin wird auch einen Einblick in die Regressionsanalyse gegeben.
Um den Faktor der Heterogenität zu berücksichtigen, gilt es entsprechende Cluster abzuleiten.
Beispielhaft wird eine Clusteranalyse plakativ an einem reduzierten Modell dargestellt. Im Fazit
wird zusammenfassend auf die bisherige Etablierung des Benchmarkings in der Immobilienwirtschaft
eingegangen sowie auf weitere Forschungsansätze hingewiesen.
This paper conducts a thorough data analysis using cross-sectional data from a study carried out in Mexico including over 16,500 observations. In the study, clusters were selected in areas Compartamos Banco, a Microfinance institution (MFI), has not lent in before. The clusters were randomly assigned to either the treatment or the control group. The analysis suggests that Microfinance has a significant positive effect on school and food expenditure but no apparent effect on entrepreneurship. Using regression analysis, a significant positive effect on women’s empowerment and its positive effect on total consumption is found.
Der vorliegende Text basiert einerseits auf den Ergebnissen von studentischen Arbeiten, welche im Sommersemester 2018 und im Wintersemester 2018/2019 am IMI erstellt wurden. Weiter trafen sich die Autoren Prof. Dr. Georg Rainer Hofmann und Meike Schumacher (beide TH Aschaffenburg) über ein Jahr ca. alle zwei Monate zu jeweils zweistündigen Gesprächen mit Vertretern der KAB (Herr Joachim Schmitt, Herr Peter Hartlaub) und der IG Metall (Herr Percy Scheidler, Frau Manuela Lüft, Herr Simon Kruppa), sowie Herr Rudi Grossmann, ehemaliger Kreisvorsitzender des Deutschen Gewerkschaftsbundes (DGB), der auch Mitglied der KAB ist. Es wurden in diesen Gesprächen eine Vielzahl von Erkenntnissen und Perspektiven zum Thema der „Neuen Arbeitswelt“ identifiziert. Frau Lucia Falkenberg, Chief People Officer (CPO) und Leiterin der Kompetenzgruppe New Work des eco – Verband der Internetwirtschaft e. V. vertritt in der vorliegenden Studie die Perspektive der Arbeitgeber in der Digitalen Transformation (Kap. 2.4); die Arbeitgeber haben das Problem der hinreichenden Attraktivität ihrer Unternehmen bei der Gewinnung qualifizierter Fachkräfte zu gegenwärtigen.
Die Beteiligten fanden diese neuen Aspekte – insbesondere weil sie aus verschiedenen Bereichen des Bemühens um eine Humanisierung der Arbeitswelt stammen – einer Dokumentation wert. Aus diesem Grund wurde eine Ausarbeitung – als Diskussionsangebot und -beitrag – vorgenommen, in die sowohl die veränderten Rahmenbedingungen der Arbeitswelt, als auch einige Überlegungen zu politischen Handlungsoptionen geflossen sind.
We report on the joining of two different transparent thermoplastic polymers using infrared femtosecond laser pulses. Solely being based on nonlinear absorption, the developed micro-welding process for cyclo-olefin copolymers and polycarbonate does not require any intermediate absorbing layers or any surface pre-processing of the welding partners. In addition, it circumvents any heat damages at the outer surfaces of the welding partners. Femtosecond laser welding of cyclo-olefin copolymers is improved by increasing the numerical aperture of the focusing setup resulting in a wider and more homogenous welding cross-section. Welding results are classified by shear strength and fracture modes are analyzed using scanning electron microscopy. Furthermore, we demonstrate, to the best of our knowledge, first results of ultrashort pulse laser welding of transparent polycarbonate, one of the most used transparent polymers. In view of an optimized and stable micro-welding process, we study the influence of laser power and focal position on welding results. The application of ultrashort pulse laser welding for Lab-on-chip fabrication technologies is demonstrated by sealing an ultrashort pulse laser ablated microfluidic device based on a transparent polymer substrate.
Over the last years, IT Security has slowly found its way into teaching in higher education. It is becoming increasingly important to integrate knowledge about the development of secure systems (secure software engineering) into academic teaching. However, teaching security and secure software engineering to non-computer-scientists is rare. Therefore, we focus our research on the integration of IT Security into software engineering education of non-computer scientists, particularly electrical engineers, by means of inductive teaching- and learning-arrangements. As a prerequisite for inductive teaching, our paper deals with engineering and computer science students’ preconceptions of the topics IT Security and secure software engineering to identify learning contents and corresponding teaching methods to improve academic learning and teaching in both areas in the future. To identify those preconceptions, we conducted guided interviews with freshmen of engineering and computer science studies from different German Universities of Applied Sciences, containing questions about what they have heard about the topic of IT Security. The interviews were coded according to the coding process of the Grounded Theory Method of Corbin and Strauss [1], with focus on open and axial coding. The goal was to derive a first catalogue of students’ preconceptions according to IT Security and secure software engineering. We present the first version of the catalogue in the paper.
It has been suggested that information overload decreases decision-making performance. This study empirically examines the mediating role of information (over-)load on the relationships between two system features (deep structure usage and system quality) and managerial performance using a mixed-method-approach (survey and interviews). It analyzes the relationships with respect to a state-of-the-art decision support system (DSS). Our results indicate that information overload adversely affects managerial performance and mediates the influence of system quality and deep structure usage on managerial performance. We find that system quality is positively related to information overload. Drawing on cognitive load theory, we hypothesize and confirm that deep structure usage reduces perceived information overload. Additional evidence from interviews further illustrate these results and show that information overload can be influenced in counter-intuitive ways by system aspects. Our results have important implications for the design of modern information system (IS) landscapes to support managerial performance. They draw attention to the importance of information overload as a mediating factor in the interrelationship among deep structure usage, system quality and managerial performance.
This study investigates the sustainability disclosure effects of the introduction of the Companies Act 2006 Regulations 2013 in the United Kingdom. The regulation mandates the disclosure of information on greenhouse gas emissions, gender distribution and human rights issues. We examine two research questions: first, whether firms increased disclosure on the mandated topics after the regulation became effective relative to a control group, and second, whether a potential increase in disclosure is moderated by firms’ reporting incentives, namely, firms’ capital market visibility, growth orientation, governance structure, prior voluntary sustainability disclosure levels and critical media coverage. Our sample consists of the FTSE-350 firms and a matched control group of US firms. We use textual analysis to assess the disclosure of the mandated sustainability topics in firms’ annual reports. Specifically, we examine two types of disclosure, namely, the disclosure of the mandated key performance indicators and the narrative disclosure. Our results reveal a significant increase for both types of disclosure relative to the control group. Overall, this treatment effect tends to be smaller for firms with higher reporting incentives, i. e., reporting incentives mitigate the regulatory effect. Taken together, our results suggest that both standards and reporting incentives shape firms’ sustainability disclosure level.
Abstract
Purpose
This study aims to investigate the role of environmental management control systems as mechanisms to translate environmental strategy into environmental managerial performance.
Design/methodology/approach
Based on survey data from 218 firms, the authors test a structural equation model.
Findings
The results show that environmental management control systems mediate the relationship between environmental strategy and environmental managerial performance. Moreover, the level of integration between regular and environmental management control systems significantly impacts the relationship between environmental management control systems and environmental managerial performance. Therefore, environmental management control systems are important mechanisms to translate environmental strategy into managerial performance, and a high level of integration can reinforce this role.
Research limitations/implications
The typical shortcomings of survey-based research apply to this study.
Originality/value
While previous research focuses primarily on environmental performance at the organizational level, this study addresses individual managerial performance with regard to environmental outcomes. In addition, the authors investigate how the level of integration between regular and environmental management control systems influences the relationship between environmental strategy and environmental managerial performance as well as the mediating role of environmental management control systems.
In the light of the information age, information overload research in new areas (e.g., social media, virtual collaboration) rises rapidly in many fields of research in business administration with a variety of methods and subjects. This review article analyzes the development of information overload literature in business administration and related interdisciplinary fields and provides a comprehensive and overarching overview using a bibliometric literature analysis combined with a snowball sampling approach. For the last decade, this article reveals research directions and bridges of literature in a wide range of fields of business administration (e.g., accounting, finance, health management, human resources, innovation management, international management, information systems, marketing, manufacturing, or organizational science). This review article identifies the
major papers of various research streams to capture the pulse of the information overload-related research and suggest new questions that could be addressed in the future and identifies concrete open gaps for further research. Furthermore, this article presents a new framework for structuring information overload issues which extends our understanding of influence factors and effects of information overload in the decision-making process.
Sales engineers (SE) sell technical products and services to companies,
and their results are crucial for their employers. They need technical
knowledge and commercial competencies, but also management and soft skills,
all fundamental for SE to be highly performant in their job. Students cannot
learn this variety neither at university nor in industry alone. Instead, cooperation
is required. Whereas academic-industrial cooperation for research or specific
study programs is discussed in literature, this is not yet the case for enhanced
industrial involvement in students’ education. The authors present two case
studies of industrial implication in students’ education in Germany and France
as benchmark and basis for a new approach of academic-industrial cooperation
in education in Finland. This cooperation is developed in the frame of the
project ‘RADICAL - Filling Skills Gaps in Blue Industry by Radical Competence
Boost in Engineering VET’, co-funded by the Erasmus+ program of the
European Union.
The rapidly growing maritime industry of Southwestern Finland is suffering from lack of engineers.
Industrial Management Engineers including Sales Engineers have technical knowledge and commercial
competencies as well as management and soft skills, which are all fundamental for the maritime sector.
However, it takes rather long time before a graduated engineer will be a productive worker for the
company. A solution to getting the students faster operational into the companies is to deepen cooperation
between higher education and industry during the studies and increase workplace based learning following
the examples available in e.g. Germany and France. The authors present a new approach of academicindustrial
cooperation in education in Finland which is developed in the frame of the project ‘RADICAL -
Filling Skills Gaps in Blue Industry by Radical Competence Boost in Engineering VET (VET: Vocational
Education and Training)’, co-funded by the Erasmus + program of the European Union.
This contribution discusses the integration of polymer planar Bragg grating sensors (PPBG) into carbon fiber reinforced polymer (CFRP) components. For the first time, it is shown that PPBGs based on cyclic olefin copolymers can be integrated into commercial-grade composites, thereby withstanding the demanding production processes. Pre-impregnated fibers are stacked and partially modified to form a sensor pocket. Afterwards, the CFRP specimen containing the optical sensor is cured in a heated mechanical press for 2 hours at a pressure of 7 bar and a temperature of 120 °C. A subsequent evalutaion of the sensor signal shows a Bragg wavelength shift of 1236 pm and a decline in signal amplitude of -2 dB. Three-point flexural tests of the cured sample reveal a linear behavior of the sensor signal towards external loads. The determined sensitivity in dependence of the CFRP specimen's maximum central deflection is -112 pm/mm, while correlation to the applied force results in a sensitivity of -5 pm/N.
