The purpose of this paper is to examine the relationship between the consumers’ perception of sustainability and the application of a QR-code in stores with the focus on the information searching behavior regarding sustainable aspects. An online questionnaire was conducted with fashion students at Reutlingen University: in total, 65 students participated in the survey. Paired samples t-test and other statistical analyses were applied to test research questions. Apart from this, the research paper is based on a literature review. Furthermore, the decision was taken to use a projective method in the form of a dummy fashion fTRACE website. Key findings of the survey are that participants give sustainable aspects a higher importance with a QR-code than without one. Participants who prefer a product with detailed information experience a “positive shopping feeling” when provided with transparency via a QR-code. “Origin”, “production” and “quality” were rated of higher importance by those participants. These findings suggest that, transparency provided through the application of a QR-Code in stores influences the consumers’ perception of sustainability. Due to the small sample size of participants (65) in the study, findings of this research not generalizable to a larger population. This paper focused on the consumers’ information searching behavior regarding sustainable aspects, limiting its findings to impacts on perception of sustainability. Further research is therefore recommended.
Anhaltend hohe Mitarbeitermotivation ist die zentrale Voraussetzung für erfolgreichen Vertrieb. Doch viel zu häufig versuchen Unternehmen, ihre Vertriebsmitarbeiter allein durch Einzelimpulse und durchsichtige Anreizsysteme zu motivieren. Dies kann nicht gelingen. Stattdessen sind eine langfristige Perspektive und ein intelligenter Mix verschiedener Instrumente nötig.
"Wer nicht vielfältig denkt, denkt einfältig". Mit diesem Spruch machen Studierende der Hochschule Reutlingen in einem Videoclip auf das Thema Diversity aufmerksam. Doch was verstehen wir eigentlich darunter? Seit September letzten Jahres ist Professorin Dr. Gabriela Tullius Vizepräsidentin der Hochschule Reutlingen und widmet sich unter anderem diesem Bereich. GEA-Campus hat nachgefragt, worum es bei Diversity geht und warum dieser Bereich die Hochschule beschäftigt.
Methacrylated gelatin and mature adipocytes are promising components for adipose tissue engineering
(2016)
In vitro engineering of autologous fatty tissue constructs is still a major challenge for the treatment of congenital deformities, tumor resections or high-graded burns. In this study, we evaluated the suitability of photo-crosslinkable methacrylated gelatin (GM) and mature adipocytes as components for the composition of three-dimensional fatty tissue constructs. Cytocompatibility evaluations of the GM and the photoinitiator Lithium phenyl-2,4,6 trimethylbenzoylphosphinate (LAP) showed no cytotoxicity in the relevant range of concentrations. Matrix stiffness of cell-laden hydrogels was adjusted to native fatty tissue by tuning the degree of crosslinking and was shown to be comparable to that of native fatty tissue. Mature adipocytes were then cultured for 14 days within the GM resulting in a fatty tissue construct loaded with viable cells expressing cell markers perilipin A and laminin. This work demonstrates that mature adipocytes are a highly valuable cell source for the composition of fatty tissue equivalents in vitro. Photo-crosslinkable methacrylated gelatin is an excellent tissue scaffold and a promising bioink for new printing techniques due to its biocompatibility and tunable properties.

Tumorzellen on the move : mikrosystem-basierter Assay zur Untersuchung der Tumorzellen-Migration
(2016)
Die Invasion von Tumorzellen in umliegendes Gewebe und die Bildung von Metastasen transformieren einen lokal wachsenden Tumor in eine systemische und lebensbedrohliche Krankheit mit schlechter Prognose. Dabei spielt die aktive Migration der Tumorzellen eine entscheidende Rolle. Tumorzellen gelangen durch die aktive Zellbewegung in das Lymph- oder Blutsystem und breiten sich im Körper aus. Bei der Invasion in ein neues Organ migrieren die Zellen ebenfalls wieder in komplexer Weise durch das Gewebe und können schließlich dort Metastasen bilden. Auf Grund der enormen medizinischen Relevanz der Tumorzell-Invasion, wird die Bewegung von Tumorzellen seit Jahrzehnten unter Laborbedingungen umfassend untersucht und ist ein wichtiger Marker für die Aggressivität der Tumorzellen. Zur Bewegungsanalyse gibt es mehrere experimentelle und auch kommerziell erhältliche in-vitro Untersuchungsmethoden. Ziel des interdisziplinären Projektes „MigChip“ ist die Entwicklung, Herstellung und experimentelle Validierung eines Mikrofludik-Chips zur verbesserten, detailgenauen in-vitro Untersuchung der Tumorzellen-Migration.
The extracellular environment of vascular cells in vivo is complex in its chemical composition, physical properties, and architecture. Consequently, it has been a great challenge to study vascular cell responses in vitro, either to understand their interaction with their native environment or to investigate their interaction with artificial structures such as implant surfaces. New procedures and techniques from materials science to fabricate bio-scaffolds and surfaces have enabled novel studies of vascular cell responses under well-defined, controllable culture conditions. These advancements are paving the way for a deeper understanding of vascular cell biology and materials–cell interaction. Here, we review previous work focusing on the interaction of vascular smooth muscle cells (SMCs) and endothelial cells (ECs) with materials having micro- and nanostructured surfaces. We summarize fabrication techniques for surface topographies, materials, geometries, biochemical functionalization, and mechanical properties of such materials. Furthermore, various studies on vascular cell behavior and their biological responses to micro- and nanostructured surfaces are reviewed. Emphasis is given to studies of cell morphology and motility, cell proliferation, the cytoskeleton and cell-matrix adhesions, and signal transduction pathways of vascular cells. We finalize with a short outlook on potential interesting future studies.
Purpose – The purpose of this paper is to discuss the applicability of current benchmarking proposals for small and medium-sized enterprises (SMEs) and to suggest a condensed process for logistics benchmarking in SMEs.
Design/methodology/approach – The paper starts by outlining why the logistics function is of increasing importance for SMEs. It discusses the benefit of logistics benchmarking and typical SME restrictions in benchmarking. Available approaches to benchmarking are discussed and their weaknesses when applied to SME logistics benchmarking are analyzed. The paper develops a new benchmarking process framework for SME logistics benchmarking and reports findings of a case application in three German SMEs.
Eine gut funktionierende Logistik ist ein wichtiger Wettbewerbsfaktor. Um ihren Beitrag zum Unternehmenserfolg ermitteln zu können, müssen ihre Kosten aber bestimmbar sein. Daran hapert es häufig. Dabei gibt es Ansätze, um Logistikkosten von anderen Kosten abzugrenzen. Unternehmen müssen nur konkrete Regeln für ihren Einsatz berücksichtigen.
