In this article, liposome-based coatings aiming to control drug release from therapeutic soft contact lenses (SCLs) materials are analyzed. A PHEMA based hydrogel material loaded with levofloxacin is used as model system for this research. The coatings are formed by polyelectrolyte layers containing liposomes of 1,2-dimyristoyl-sn-glycero-3- phosphocholine (DMPC) and DMPC1cholesterol (DMPC1 CHOL). The effect of friction and temperature on the drug release is investigated. The aim of the friction tests is to simulate the blinking of the eyelid in order to verify if the SCLs materials coated with liposomes are able to keep their properties, in particular the drug release ability. It was observed that under the study conditions, friction did not affect significantly the drug release from the liposome coated PHEMA material. In contrast, increasing the temperature of release leads to an increase of the drug diffusion rate through the hydrogel. This phenomenon is recorded both in the control and in the coated samples.
In this study, a novel strategy has been developed for the assembly of polyelectrolyte multilayer (PEM) on CaCO3 templates in acidic pH solutions, where consecutive polyelectrolyte layers (heparin/poly(allylamine hydrochloride) or heparin/chitosan) were deposited on PEM hollow microcapsules established previously on CaCO3 templates. The PEM build-up, hollow capsule characterization and successful encapsulation of fluorescein 5(6)-isothiocyanate (FITC)-Dextran by coprecipitation with CaCO3 are demonstrated. Improvement by the removal of CaCO3 core was achieved while the depositions. In the course of the release profile, high retardation for encapsulated FITC-Dextran was observed. The combined shell capsules system is a significant trait that has potential use in tailoring functional layer-by-layer capsules as intelligent drug delivery vehicles where the preliminary in vitro tests showed the responsiveness on the enzymes.
This article covers the design of highly integrated gate drivers and level shifters for high-speed, high power efficiency and dv/dt robustness with focus on automotive applications. With the introduction of the 48 V board net in addition to the conventional 12 V battery, there is an increasing need for fast switching integrated gate drivers in the voltage range of 50 V and above. State-of-the-art drivers are able to switch 50 V in less than 5 ns. The high-voltage electrical drive train demands for galvanic isolated and highly integrated gate drivers. A gate driver with bidirectional signal transmission with a 1 MBit/s amplitude modulation, 10/20 MHz frequency modulation and power transfer over one single transformer will be discussed. The concept of high-voltage charge storing enables an area-efficient fully integrated bootstrapping supply with 70 % less area consumption. EMC is a major concern in automotive. Gate drivers with slope control optimize EMC while maintaining good switching efficiency. A current mode gate driver, which can change its drive current within 10 ns, results in 20 dBuV lower emissions between 7 and 60 MHz and 52 % lower switching loss compared to a conventional constant current gate driver.
Die Organisationsentwicklung hat eine bewegte Geschichte hinter sich und eine aussichtsreiche Zukunft vor sich. Die Kerngedanken der Organisationsentwicklung, die wesentlich durch die Forschungen von Kurt Lewin und Kollegen beeinflusst wurden, haben die theoretischen Vorstellungen über und praktische Handhabung von intentional gesteuerten Veränderungsprozessen wesentlich beeinflusst. Nachdem die Organisationsentwicklung über die Zeit strategischer und pragmatischer geworden ist, droht sie als eigenständige Methode zunehmend unkenntlich zu werden. In diesem Beitrag wird anhand von zwei Thesen argumentiert, dass eine zukunftsfähige Organisationsentwicklung die Grundidee der Partizipation in einer digitalen Arbeitswelt wieder stärken und sich reflektierter als bislang dem paradoxen Verhältnis zwischen Stabilität und Wandel annehmen müsste. Eine Organisationsentwicklung, die sich mit diesen Themen beschäftigt, ist zukunftsfähig und wird wesentlich die Art und Weise prägen, wie in Organisationen Veränderungen gestaltet werden.
The influence of turbidity on the Raman signal strengths of condensed matter is theoretically analyzed and measured with laboratory - scale equipment for remote sensing. The results show the quantitative dependence of back- and forward-scattered signals on the thickness and elastic-scattering properties of matter. In the extreme situation of thin, highly turbid layers, the measured Raman signal strengths exceed their transparent analogs by more than a factor of ten. The opposite behavior is found for thick layers of low turbidity, where the presence of a small amount of scatterers leads to a decrease of the measured signal. The wide range of turbidities appearing in nature is experimentally realized with stacked polymer layers and solid/liquid dispersions, and theoretically modeled by the equation of radiative transfer using the analytical diffusion approximation or random walk simulations.
Green fashion retail
(2017)
This book focuses on sustainability in fashion retail, which is fast becoming the pivot point of future fashion retail strategies. Chapters in the book provide theoretical and practical insight on how going green may positively influence the strategy of fashion retailers and marketers, who have to react to the changing society and customer needs. Structured in four main parts, and based on distinct research questions, readers will be able to dig deep into the individual levers for possible adaptions. It thus provides a solid understanding on how to integrate green aspects into any fashion retailers business model.
The purpose of this paper is to explain the key aspects and growing relevance of sustainability in fashion retail and to evaluate the possibilities of fashion retailers to act sustainable in supply chain management as well as carving out the challenges they have to deal with. The research methodology applied for this purpose is a critical literature review examining books and articles. The findings demonstrate the rising importance of sustainability in fashion retail. In this regard, fashion retailers play a key role and responsibility for sustainability in the fashion supply chain, from the beginning up to the end. This paper mainly analyzes sustainability in the fashion supply chain. It does not analyze topics like second-hand shopping or social media sustainability.
The purpose of this paper is to investigate how the practice of closed-loop production systems (CLPS) is implemented in the fashion industry. This paper offers a critical literature review to present a thorough understanding of the actual status of literature. Subsequently, the paper reveals that CLPS are of great importance. Generally, such systems include different activities that have to be integrated. Critical points are the product acquisition, the recovering process itself and the remarketing to the customer. A lack of reliable data concerning CLPS in the specific case of fashion industry can be identified. Important research fields could be marketing strategies, controlling the acquisition process, evolvement of return technologies and strategies, adaption of recovered products to the mass market, and the development of new technologies concerning recovering processes.
The purpose of this paper is to examine the impact on sustainability of fashion production and consumption in order to discuss what the main lever is to reduce the negative impact. The research methodology applied is a literature review examining academic references. Key findings suggest that fashion production and consumption have a single comparable impact on sustainability. Moreover, as the fashion production follows the demand, the consumer steers the production in a certain direction. Therefore, consumers take over responsibility and need to be informed. To reach a long-term change in the fashion industry, the consumer has to be the focus of the sustainable efforts. Most results in literature were conducted by qualitative research methods, so that further quantitative testing of the results is recommended. Furthermore, most surveys were conducted with young fashion consumers in the EU or UK which does not represent the fashion consumer in general.
The purpose of this paper is to define what impacts sustainable manufacturing standards have for retail brands concerning the communication policy and to find possible solutions of how the companies can deal with them. Therefore, sustainable standards and the impacts on the internal and external communication are described. The enclosed discussion finds possible solutions for the negative impacts. A literature discussion has been conducted to investigate the purpose. Generally, there are many impacts fashion retails have to consider, if they want to transform their company to become more sustainable, because only the impacts on a defined part of the communication policy were huge. A limitation of this paper is that the proposals how retailers could deal with the impacts of the transformation of the company toward more sustainability need further research and tests until they are practicable.
The purpose of this paper is to highlight potentials and limitations of the prosumer concept in fashion retail. The paper illustrates the evolution of prosumption and in which directions the concept is being developed. The primary research is based on a literature review containing different sources of academic and non-academic references. Findings suggest that the prosumer concept is no new phenomenon. Recently, it has moved into the focus of companies that have noted that it is efficient when engaging with customers in order to strengthen their brand loyalty. An increasing number of companies offer innovative business models that underlie the concept. However, lately smart prosuming machines are changing the objectives of the concept. Even if the prosumer concept exists since many years and scholars investigate its potentials continuously, it is the fashion industry that has been researched comparatively little up to now.
The second hand concept indicates a growing trend in clothing recently, leading to growing numbers of second hand shops and developments of new second hand retail forms. This paper concentrates on the current second hand market for fashion products and presents the different motives toward second hand consumption as well as alternative consumption channels for second hand products. The findings of the paper are founded on literature research of academic articles and case studies. Results show that there is a high potential for the second hand market due to the increasing interest of consumers in buying second hand products. The paper concentrates on the second hand market for fashion products in the western society. This means that there was no research on second hand products for disadvantaged people in poor countries. Furthermore, the paper focuses the formal second hand retail channels to see what is already on the market.
The purpose of this paper is to evaluate consisting consumption patterns caused by fast fashion with a new appearing form of consumption and retaining potentials as an alternative as well as sustainable form of fast fashion consumption. This research is set up on a theoretical background of scientific literature including governmental as well as press releases in order to evaluate the status quo of consumption and answering the research question. A new consumption pattern as well as an appearing economy of sharing can be stated including potential aspects of raising businesses and sustainable alternative forms of fast fashion. The framework of the research is limited to the textile and fashion industry in industrialized countries focusing on consumption in the twenty first century.
The purpose of this research is to explore current boundaries of the fashion industry’s second hand market and which solutions and approaches can be adopted from the used-car industry. The paper is based on the study of existing literature which deals with sustainability in combination with second hand markets in general and adaptable features of the used-car industry. Adaptable features are found using the business model canvas. The key finding of this study indicates that the fashion industry faces immense social and environmental challenges which can be partly solved by the development of the second hand market. Used-car industry can be seen as role model for fashion retail. In this study only aspects of used-car distribution are highlighted; therefore, characteristics of the recycling of used cars are not examined.
The purpose of this paper is to study the recycling form of reusing second hand clothing from a conventional fashion brand’s perspective. It should clarify which measures and activities a fashion company needs to integrate in its value chain in order to offer branded second hand merchandise in a self-operated store. The research paper relies on a desk-based research and aims to illustrate the topic by means of a descriptive approach, processing the existing literature. Key findings demonstrate that fashion brands need to integrate complete lifecycle strategies, sustainability communication, and reverse logistics structures, like take-back schemes, for offering second hand clothing. The main limitations evolve from the research design. Further, empirical evidences need to be conducted for a more fundamental understanding of the new business model.
The purpose of this paper is to investigate the use of sustainable closed-loop supply chain of the fashion brand Filippa K. Information on green fashion has been gathered and a case study approach on the fashion retailer
Filippa K conducted. Results show a switch in knowledge content between a fast fashion supply chain and a sustainable supply chain. Also there is an evolution in sustainability as companies, retailers, and manufactures suffer under pressure from the customers, governments, and the media. Sustainable fashion brands like Filippa K are interested in sharing precise knowledge on variety of aspects linked to the sustainable closed-loop supply chain. This research paper has been limited by less information and unexplored topics in the theme green fashion. This led to the personal critical disputation with the brand Filippa K.
This study focuses on the different roles of social media for the promotion of a sustainable lifestyle, behaviour and consumption, especially with regard to the typically non-ethical fashion industry. Research findings include eight roles of social media influencing a sustainable consumption contrary to prior research naming one to five impacts. Results show that social media educates and engages the young and ethically interested target group besides increasing supply chain transparency and brand or theme awareness. Furthermore, social media provides a platform for organisations’ relationship management and social interaction since users get empowered to share experiences which leads to a higher level of trust.
The purpose of this paper is to identify the potential of a fashion fTRACE (ffTRACE) application that gives transparent insight on the supply chain of a fashion item. The research methodology applied to this purpose is a literature review examining academic references. The key findings of this paper are that information plays a major role in the consumer decision process and is therefore beneficial to the demand for sustainable products. Given the right information content in a transparent, credible and understandable way is important. It is found that the functions of such an application would be able to satisfy this consumer demand and therefore has the potential to raise the sales of a sustainable company as well as increase the brand’s awareness and improve its image. While mainly indicating the potentials of the ffTRACE application, their relevance is not examined in this paper.
Since there is no denying that transparency is increasingly central to corporate sustainability, the purpose of this paper is a case study on a company’s attempt to be fully transparent, hence, picking up the existent scholarly conversation about uncompromising supply chain transparency. Literature so far was found to be fairly limited, but, following a trend, has been rising in numbers over recent years. Addressing these shortcomings in the methodology, an in-depth literature review about the multiple dimensions of supply chain transparency has been performed and links within supply networks stressed. On this basis, a case study by exemplary illustrating the fashion label Honestby has been drafted and the effort to become the world’s first 100 % transparent company further examined. Findings are discussed whether more supply chain transparency is desirable in any case, obstacles listed and an outlook for this kind of business model has been drawn. The research is clearly limited by the amount of scholarly literature concerning Honestby in particular. Out of this reason, magazines and journal entries are used as reference as well. Only with the extension of the topic itself to supply chain transparency and the literature review beforehand, the paper gained its necessary academic standard. Concerning implications, it needs to be mentioned that even though Honest by demonstrates to be fully transparent, it was not possible to find any public information about the degree of supplier relationship. In particular, concerning the applied control mechanisms used to exert influence and to balance out the power gradient between company and suppliers.
Social networks, smart portable devices, Internet of Things (IoT) on base of technologies like analytics for big data and cloud services are emerging to support flexible connected products and agile services as the new wave of digital transformation. Biological metaphors of living and adaptable ecosystems with service-oriented enterprise architectures provide the foundation for self-optimizing and resilient run-time environments for intelligent business services and related distributed information systems. We are extending Enterprise Architecture (EA) with mechanisms for flexible adaptation and evolution of information systems having distributed IoT and other micro-granular digital architecture to support next digitization products, services, and processes. Our aim is to support flexibility and agile transformation for both IT and business capabilities through adaptive digital enterprise architectures. The present research paper investigates additionally decision mechanisms in the context of multi-perspective explorations of enterprise services and Internet of Things architectures by extending original enterprise architecture reference models with state of art elements for architectural engineering and digitization.
Social sustainable supply chain management in the textile and apparel industry : a literature review
(2017)
So far, a vast amount of studies on sustainability in supply chain management have been conducted by academics over the last decade. Nevertheless, socially related aspects are still neglected in the related discussion. The primary motivation of the present literature review has arisen from this shortcoming, thus the key purpose of this study is to enrich the discussion by providing a state of-the-art, focusing exclusively on social issues in sustainable supply chain management (SSCM) by considering the textile/apparel sector as the field of application. The authors conduct a literature review, including content analysis which covers 45 articles published in English peer-reviewed journals, and proposes a comprehensive map which integrates the latest findings on socially related practices in the textile/apparel industry with the dominant conceptualization in order to reveal potential research areas in the field. The results show an ongoing lack of investigation regarding the social dimension of the triple bottom line in SSCM. Findings indicate that a company’s internal orientation is the main assisting factor in sustainable supply chain management practices. Further, supplier collaboration and assessment can be interpreted as an offer for suppliers deriving from stakeholders and a focal company’s management of social risk. Nevertheless, suppliers do also face or even create huge barriers in improving their social performance. This calls for more empirical research and qualitative or quantitative survey methods, especially at the supplier level located in developing countries.
Purpose: Human breath analysis is proposed with increasing frequency as a useful tool in clinical application. We performed this study to find the characteristic volatile organic compounds (VOCs) in the exhaled breath of patients with idiopathic pulmonary fibrosis (IPF) for discrimination from healthy subjects. Methods: VOCs in the exhaled breath of 40 IPF patients and 55 healthy controls were measured using a multi-capillary column and ion mobility spectrometer. The patients were examined by pulmonary function tests, blood gas analysis, and serum biomarkers of interstitial pneumonia. Results: We detected 85 VOC peaks in the exhaled breath of IPF patients and controls. IPF patients showed 5 significant VOC peaks; p-cymene, acetoin, isoprene, ethylbenzene, and an unknown compound. The VOC peak of p-cymene was significantly lower (p < 0.001), while the VOC peaks of acetoin, isoprene, ethylbenzene, and the unknown compound were significantly higher (p < 0.001 for all) compared with the peaks of controls. Comparing VOC peaks with clinical parameters, negative correlations with VC (r =−0.393, p = 0.013), %VC (r =−0.569, p < 0.001), FVC (r = −0.440, p = 0.004), %FVC (r =−0.539, p < 0.001), DLco (r =−0.394, p = 0.018), and %DLco (r =−0.413, p = 0.008) and a positive correlation with KL-6 (r = 0.432, p = 0.005) were found for p-cymene. Conclusion: We found characteristic 5 VOCs in the exhaled breath of IPF patients. Among them, the VOC peaks of p-cymene were related to the clinical parameters of IPF. These VOCs may be useful biomarkers of IPF.
This paper investigates the electrothermal stability and the predominant defect mechanism of a Schottky gate AlGaN/GaN HEMT. Calibrated 3-D electrothermal simulations are performed using a simple semiempirical dc model, which is verified against high-temperature measurements up to 440°C. To determine the thermal limits of the safe operating area, measurements up to destruction are conducted at different operating points. The predominant failure mechanism is identified to be hot-spot formation and subsequent thermal runaway, induced by large drain–gate leakage currents that occur at high temperatures. The simulation results and the high temperature measurements confirm the observed failure patterns.

In times of dynamic markets, enterprises have to be agile to be able to quickly react to market influences. Due to the increasing digitization of products, the enterprise IT often is affected when business models change. Enterprise Architecture Management (EAM) targets a holistic view of the enterprise’ IT and their relations to the business. However, Enterprise Architectures (EA) are complex structures consisting of many layers, artifacts and relationships between them. Thus, analyzing EA is a very complex task for stakeholders. Visualizations are common vehicles to support analysis. However, in practice visualization capabilities lack flexibility and interactivity. A solution to improve the support of stakeholders in analyzing EAs might be the application of visual analytics. Starting from a systematic literature review, this article investigates the features of visual analytics relevant for the context of EAM.
The management of football brands : brand identity management illustrated by Borussia Dortmund
(2017)
Despite a growing awareness of the importance of the management of trademarks at the club level, there is a significant delay regarding the professional management of the brand within the Bundesliga clubs. So far, the principles of brand identity management were rarely applied, and most clubs have given up, despite a high economic potential, the ability to create competitive advances in economic terms, but also in sports terms. In this chapter, we will study the success factors of the management of brand identity of professional football clubs from the actual case of Borussia Dortmund.
Customer prioritization is a common marketing activity in business practice. It aims at an increase in average customer profitability and return on sales by treating important customers more intensively. After a short introduction highlighting the importance of customer prioritzation, the present article provides an overview of key aspects of customer prioritization. First, companies need to select a prioritization criterion, determine the method to identify important customers, and decide on how to treat these customers in a particular way. Second, companies face challenges and need to address key requirements for implementing customer prioritization within a company. Finally, the article emphasizes positive and negative consequences of customer prioritization.
While the topic of Customer Relationship Management (CRM) has generated an increasing amount of research attention in recent years, still lacking is a comprehensive overview that helps to explain how companies can implement CRM successfully. To address these issues, this article identifies and discusses factors that are associated with a greater degree of CRM success. More specifically, we identify and discuss determinants on strategy, human resources, information management, structure and processes as well as specific factors within the implementation phase which help to improve CRM success. First, our results indicate that the implementation of CRM processes is associated with better company performance, especially at the relationship initiation and maintenance stage. Second, the findings emphasis a predominant influence of firm-based factors vis-à-vis structural industry, and customer-based factors. Furthermore, cross-functional CRM teams and a top management feeling responsible for CRM projects help to improve CRM success. In addition, internal processes which are related to customer contact points have to be redesigned to enhance the interaction between employees and customers. The current article sheds more light on what really drives CRM success.
We present a fully automatic approach to real-time 3D face reconstruction from monocular in-the-wild videos. With the use of a cascaded-regressor-based face tracking and a 3D morphable face model shape fitting, we obtain a semidense 3D face shape. We further use the texture information from multiple frames to build a holistic 3D face representation from the video footage. Our system is able to capture facial expressions and does not require any person specific training. We demonstrate the robustness of our approach on the challenging 300 Videos in the Wild (300- VW) dataset. Our real-time fitting framework is available as an open-source library at http://4dface.org.
It is assumed that more education leads to better understanding of complex systems. Some researchers, however, find indications that simple mechanisms like stocks and flows are not well understood even by people who have passed higher education. In this paper, we test people’s understanding of complex systems with the widely studied stock-and-flow (SF) tasks. SF tasks assess people’s understanding of the interplay between stocks and flows. We investigate SF failure of domain experts and novices in different knowledge domains. In particular, we compare performance on the original study’s bathtub task with the square wave pattern with two alternative cover stories from the engineering and business domains on different groups of business and engineering students from different semesters. Further, we show that, while engineering students perform better than business students, with progressing in higher education, students may lose the capability of dealing with simple SF tasks. We thus find hints on déformation professionelle in higher education.
Nowadays CHP units are discussed for the production of electricity on demand rather than for generation of heat providing electricity as a by-product. By this means, CHP units are capable of satisfying a higher share of the electricity demand on-site and in this new role, CHP units are able to reduce the load on the power grid and to compensate for high fluctuations of solar and wind power.
Evidently, a novel control strategy for CHP units is required in order to shift the operation oriented at the heat demand to an operation led by the electricity demand. Nevertheless, the heat generated by the CHP unit needs to be utilized completely in any case, for maintaining energy as well as economic efficiency. Such a strategy has been developed at Reutlingen University, and it will be presented in the paper. Part of the strategy is an intelligent management for the thermal energy storage (TES) ensuring that the storage is at low level in terms of its heat content just before an electricity demand is calling the CHP unit into operation. Moreover, a proper forecast of both, heat and electricity demand, is incorporated and the requirements of the CHP unit in terms of maintenance and lifetime are considered by limiting the number of starts and stops per unit time and by maintaining a certain minimum length of the operation intervals.
All aspects of this novel control strategy are revealed in the paper, which has been implemented on a controller for further testing at two sites in the field. Results from these tests are given as well as results from a simulation model, which is able to evaluate the performance of the control strategy for an entire year.
THE PROBLEM: Companies create problems for customers and employees when product innovation goes unmanaged. Eventually, excessive operational complexity hurts the bottom line.
THREE SOLUTIONS: Focus on product integration, not product proliferation. Make sure your product developers work closely with customerfacing and operational employees. And settle on a high-level purpose that can guide decision making.
Propofol is an intravenous anesthetic. Currently, it is not possible to routinely measure blood concentration of the drug in real time. However, multi-capillary column ion-mobility spectrometry of exhaled gas can estimate blood propofol concentration.Unfortunately, adhesion of volatile propofol on plastic materials complicates measurements. Therefore, it is necessary to consider the extent to which volatile propofol adheres to various plastics used in sampling tubing. Perfluoralkoxy (PFA), polytetrafluorethylene (PTFE), polyurethane (PUR), silicone, and Tygon tubing were investigated in an experimental setting using a calibration gas generator (HovaCAL). Propofol gas was measured for one hour at 26 °C, 50 °C, and 90 °C tubing temperature. Test tubing segments were then flushed with N2 to quantify desorption. PUR and Tygon sample tubing absorbed all volatile propofol. The silicone tubing reached the maximum propofol concentration after 119 min which was 29 min after propofol gas exposure stopped. The use of PFAor PTFE tubing produced comparable and reasonably accurate propofol measurements. The desaturation time for the PFA was 10 min shorter at 26 °C than for PTFE. PFA tubing thus seems most suitable for measurement of volatile propofol,with PTFE as an alternative.
We report the temperature dependence of metal-enhanced fluorescence (MEF) of individual photosystem I (PSI) complexes from Thermosynechococcus elongatus (T. elongatus) coupled to gold nanoparticles (AuNPs). A strong temperature dependence of shape and intensity of the emission spectra is observed when PSI is coupled to AuNPs. For each temperature, the enhancement factor (EF) is calculated by comparing the intensity of individual AuNP-coupled PSI to the mean intensity of ‘uncoupled’ PSI. At cryogenic temperature (1.6 K) the average EF was 4.3-fold. Upon increasing the temperature to 250 K the EF increases to 84-fold. Single complexes show even higher EFs up to 441.0-fold. At increasing temperatures the different spectral pools of PSI from T. elongatus become distinguishable. These pools are affected differently by the plasmonic interactions and show different enhancements. The remarkable increase of the EFs is explained by a rate model including the temperature dependence of the fluorescence yield of PSI and the spectral overlap between absorption and emission spectra of AuNPs and PSI, respectively.

Aus ähnlichen Beweggründen, die Ferdinand von Steinbeis im Großen verfolgte, ist es den Bemühungen des Textilfachlehrers Reichelt und dem damaligen Prof. Stängle zu verdanken, dass gegen Ende des 19. Jahrhunderts an der in der Zwischenzeit zum Technikum für Textilindustrie avancierten Reutlinger Textilanstalt eine reichhaltige Sammlung von Modellen und Gewebemustern eingerichtet und aufgebaut wurde. Den Schwerpunkt der aus über 500000 Mustern und Gewebefragmenten bestehenden Kollektion bilden europäische Jacquard-Gewebe und engliche Anzugsstoffe aus dem 19. Jahrhundert. Das Glanzstück der Reutlinger Gewebesammlung bilden ... etwa 900 altjapanische Gewebefragmente aus der Zeit von 1530 bis 1880 ...
Es wird ein Verfahren zum Ermitteln von Deskriptoren DI, welche mit Eigenschaften eines Partikelkollektivs korrelieren, beschrieben. Die Deskriptoren Di werden durch Auswerten von Messsignalen, welche mittels einer optischen Reflexions- oder Transmissionsmethode ermittelt wurden, bei der Licht in das Partikelkollektiv eingestrahlt und rückreflektiertes Licht mittels eines Fotodetektors detektiert wird, ermittelt. Das Verfahren weist die folgenden Schritte auf: a) Aufnehmen eines Intensitätssignals I(t) von dem Fotodetektor, wobei das Intensitätssignals I(t) eine zeitabhängige Intensität von durch den Fotodetektor detektiertem Licht angibt; b) Erstellen eines digitalisierten Intensitätssignals It durch Digitalisieren des aufgenommenen Intensitätssignals I(t) mit einer Samplingperiode &Dgr;t innerhalb eines Abtastfensters T vorbestimmter Zeitdauer; c) Erstellen eines Satzes von Koeffizientenwerten ai durch Umwandeln des digitalisierten Intensitätssignals It mithilfe einer mathematischen, vorzugsweise surjektiven Transformation; d) Ableiten der Deskriptoren DI aus den erstellten Koeffizientenwerten. Das Verfahren und eine zu dessen Ausführung vorgesehene Vorrichtung können deutlich einfacher implementiert werden als herkömmliche Verfahren, bei denen Partikelkollektive durch Erstellen einer Sehnenlängenverteilung (CLD) untersucht werden sollen. Die mittels des Verfahrens ermittelten Deskriptoren können bei einer Prozessanalyse verwendet werden, um beispielsweise einfach und schnell erkennen zu können, wenn sich ein Partikelkollektiv anomal verhält.
Marketing mit Instagram
(2017)
In einer reizüberfluteten Konsumgesellschaft gestaltet es sich nicht immer einfach, potentielle Kunden über den passenden Kanal zu erreichen. Für die Markenpositionierung müssen steigende Budgets in die Produktion von qualitativ hochwertigen Inhalten investiert werden, um durch den wachsenden digitalen Wettbewerb Authentizität und Relevanz für den Konsumenten zu wahren. Dabei ist der Fokus längst von der reinen Werbebotschaft zum "Storytelling" gewandert. Die Bedeutung der Erlebnisqualität einer Marke rückt in den Vordergrund, denn die Zielgruppe möchte nicht nur den objektiven Mehrwert erfahren, sondern zugleich eine spannende Geschichte, die sie auch selbst mit dem Produkt oder der Dienstleistung erleben können. Durch die Zunahme des mobilen Konsums von Content finden gerade soziale Netzwerke wie Instagram bei der Planung der Marketing-Aktivitäten eines Unternehmens steigende Beachtung. Im Textileinzelhandel wird diese Erkenntnis bereits seit längerer Zeit aktiv genutzt, nicht so im deutschen Lebensmitteleinzelhandel. Vor diesem Hintergrund stellt sich die Frage, ob eine ästhetische Inszenierung von Lebensmitteln auf Instagram überhaupt beim Rezipienten ankommt? Die Antwort ist eindeutig: Amerikanische Unternehmen wie Wholefoods machen es vor. Mit über 1,9 Millionen Abonnenten und fast 2.500 geposteten Beiträgen (Stand Februar 2017) erfreut sich das Unternehmensprofil des Lebensmitteleinzelhändlers aus Texas großer Beliebtheit. Marketing mit Instagram und Le-bensmittel kann also erfolgreich verknüpft werden, aber wie? Dies soll im Rahmen der vorliegenden Arbeit untersucht werden.
Farben umgeben den Menschen tagtäglich und beeinflussen unser Befinden und Verhalten – teils bewusst, teils unbewusst. Diese Tatsache veranlasst auch das Marketing, sich mit den Wirkungen von Farben auseinanderzusetzen, um diese gezielt anwenden zu können. Der richtige Einsatz von Farben im Marketing kann die (Werbe-)Botschaft und die gewünschte Wirkung einer Aktivität oder Marke unterstützen und zudem Aufmerksamkeit bei Konsumenten generieren. Die Erkenntnisse über Wirkungen von Farben im Marketing sind somit entscheidend für die Wahrnehmung der Konsumenten sowie für den Erfolg des Marketings eines Unternehmens. Im Rahmen dieser Arbeit werden zunächst Farben und deren Wirkungen im Hinblick auf die Farbsymbolik sowie Farbkombinationen und Farbtöne beschrieben. Im Anschluss wird auf den Einsatz von Farben im Marketing eingegangen. Anhand von Beispielen aus der Marketing-Praxis werden Farben als Element der Corporate Identity sowie der Marke vorgestellt und die Anwendung von Farben in der Werbung analysiert. Zur Verdeutlichung der Wirkung von Farben im Marketing wird ein Moodboard für einen Aktionsartikel des Discounters ALDI Süd entworfen. Abschließend werden die Erkenntnisse zusammengefasst und eine Handlungsempfehlung für den Einsatz von Farben im Marketing ausgesprochen.
Geschäftsmodelle in der Energiewirtschaft : ein Kompendium von der Methodik bis zur Anwendung
(2017)
Ob Student oder Angestellter, Forscher oder Unternehmer, Politiker oder Dozent, ob im Start-up oder im Unternehmens-Oldie „Energieversorger“ – heute kommt vermeintlich keiner ohne ein gutes Geschäftsmodell aus. Warum ist das so? Was macht Geschäftsmodelle zu „fleißigen Lieschen“ nicht nur der Betriebswirtschaftslehre, sondern auch der Ingenieure, Volkswirte oder Informatiker? Das Geschäftsmodell beschreibt das Prinzip, nach dem eine Organisation Werte schafft, vermittelt und erfasst. Es ermöglicht durch diese Vereinfachung und Strukturierung eine leichtere Kommunikation und Analyse des Gesamtkonstrukts oder seiner Bestandteile. Es dient als Planungsinstrument, mit dessen Hilfe Innovationen effizienter und gezielter identifiziert werden können. Geschäftsmodelle können auf Ebene von Unternehmen oder einzelner Geschäftseinheiten entwickelt werden. Das vorliegende Kompendium dient dem Studenten wie dem Praktiker der Energiewirtschaft als methodische Basis zur eigenständigen Entwicklung von Geschäftsmodellen. Daher wird im 1. Kapitel aus Wissenschaft und Forschung abgeleitet, was ein Geschäftsmodell ist und wie es angewendet wird. Kapitel 2 beschreibt die Herausforderungen der Energiewirtschaft. Die Branche ist seit Jahrzehnten im Wandel. Neue Technologien zur (dezentralen) Erzeugung, Digitalisierung, sich wandelnde politische Ziele und Instrumente (Liberalisierung, Kernkraftausstieg, Energiewende,…) und neue Kundenbedürfnisse erfordern, dass die Unternehmen – große wie kleine, etablierte wie neue Anbieter, in öffentlichem wie in privatem Eigentum – angesichts erodierender Margen und zunehmendem Wettbewerb in diesem Umfeld erfolgversprechende Wege in die Zukunft suchen. Schon mit dem Begriff „Geschäftsmodell“ wird heute die Hoffnung eines Heilsbringers in diesem Dickicht erhofft, dem natürlich ein Strukturierungsinstrument – mehr ist das Geschäftsmodell schließlich nicht – nicht gerecht werden kann. In Kapitel 3 werden im Prinzip bekannte Geschäftsmodelle der Energiewirtschaft geschildert, sowie ihre Patterns, angelehnt an andere Branchen, ausdifferenziert. Dies sollte dem relativen Neuling den Einstieg in die Branche erleichtern und dem nach neuen Geschäftsmodellen Suchenden die Basis für eigene Innovation bieten. In Kapitel 4 werden Geschäftsmodelle für virtuelle Kraftwerke geschildert. Anhand dieses Beispiels wird auch ausgeführt, wie Geschäftsmodelle von Partnern entlang der Wertschöpfungskette ineinander greifen müssen. Im letzten Kapitel 5 wird schließlich auf Erfolgsfaktoren zur Entwicklung und Umsetzung von Geschäftsmodellen eingegangen.
Durch den Anstieg volatiler Stromerzeugung aus Wind und Sonne benötigt die deutsche Energiewirtschaft in zunehmendem Ausmaß flexibel verfügbare Leistung und Arbeit. Diese Flexibiliät können bspw. Batteriespeicher bereitstellen. In welchem Ausmaß jene diese Rolle übernehmen können und somit der Markt wachsen wird, hängt von der Professionalität der Marktakteure und den Umfeldparametern ab. Wenn diese stimmen, steigen Akteure in die Entwicklung von Geschäftsmodellen ein. Gleichzeitig streben sie an, die Weiterentwicklung dieser Umfeldparameter im eigenen Interesse zu beeinflussen, womit ein weiteres Marktpotenzial entsteht.Im Folgenden werden erkennbare Geschäftsmodelle aufgezeigt und in den Kontext der Ergebnisse aktueller Potenzialanalysen gestellt. Dabei entwickeln sich die zwei Teilmärkte für Batteriespeicher - Heimspeicher und Großspeicher - unter unterschiedlichen Rahmenbedingungen.
Wissen schaffen für klimafreundliche Energietechnik : das Erfolgsgeheimnis der Kraft-Wärme-Kopplung
(2017)
Als hocheffiziente Energieerzeugungstechnologie spielt die KWK eine wichtige Rolle bei der Energiewende und dem Klimaschutz. Gerade für den Gebäudebereich und Unternehmen kann die KWK eine wirtschaftliche und umweltschonende Möglichkeit sein, Strom und Wärme zu erzeugen. Für die Planung, Umsetzung und den Betrieb von KWK-Anlagen werden fachkundige Handwerke und Ingenieure gebraucht. Aus diesem Grund hat das Ministerium für Umwelt, Klima und Energiewirtschaft in den Jahren 2015 und 2016 zusammen mit dem Handwerkstag Baden-Württemberg ... den Qualifizierungskurs "Kraft-Wärme-Kopplung - Kompetenz für den Wärme- und Energiemarkt von heute und morgen" durchgeführt... Aufgrund des Erfolges der Seminarreihe wird diese auch 2017 ff. fortgesetzt.
This research is about Omnichannel Retailing and addresses the question how the omnichanneling of retailers in the fashion market can be measured. Our sources will include books, interviews, newspapers and scientific databases.
Omnichanneling is a current topic in the fashion market, retailers all over the world face the question on how to adapt to the challenges Omnichannel Retailing sets. We are going to define what Omnichanneling is by explaining the differences between Multiple-, Multi-, Cross- and Omnichannel Retailing. After we defined omnichanneling itself, we took a set of 26 retailers to evaluate regarding their Omnichannel capabilities. Then we create an index with criteria that can measure the Omnichannel capability of each retailer.
The Omnichannel Score is based on 31 criteria, which analyze the retailers in offline, online, mobile and social aspects enables to see differences between retailers. Our findings were that retailers in the US fashion market are more advanced in Omnichannel Retailing than retailers in the German fashion market. Our top three Omnichannel retailers were Sears with an Omnichannel Score of 91, followed by KOHL’S and Marks&Spencer, both with a Omnichannel Score of 88. The best Omnichannel Retailer from Germany was Adidas with the fourth place and an Omnichannel Score of 81.
There is no doubt that the amplification of channel integration towards an omni-channel structure is a powerful idea whose time has finally come. The digitally cross-linked world postulates all-encompassing, ubiquitous, and unobtrusive future services. In the concomitant, increasingly competitive market, retailers are starting to lay the foundation for omnichannel, meeting the expectations of a digitally cunning audience wanting their shopping experience to be as seamless and uncomplicated as possible. Nevertheless, recent researches show that there are still enough avenues for further research on omnichannel. Until now, the performance of companies was solely considered by experts from a suppliers’ point of view. It would be rather interesting to find out whether the desire to meet the increased cus-tomer expectations is also recognized by the customers themselves. This paper seeks to answering how the purchasing behavior has changed and what customers demand. In addition, it elaborates the opportunities that are promoted by omni-channel. Searching out all the effects, the paper will get to a final step, where it can be attested how the omnichannel performance of fashion and lifestyle retailers can be measured from a consumers’ perspective by developing an exclusive index. The study is confined to four fashion and lifestyle retailers: Hugo Boss AG, Levi Strauss & Co, Pull and Bear as well as COS. Using the scientific method of mystery shopping and a multi-item checklist including 54 key performance indicators, the paper aims to examine to which extend the four selected retailers provide a seamless customer journey, according to the five decision-making phases.
The purpose of this paper is to determine the relevance of social media for luxury brand management. It employs both a multi-methodological approach: After analyzing the online performance of the three luxury brands Burberry, Louis Vuitton and Gucci, the empirical research includes a survey as well as an eye tracking test executed with Tobii Studio. The findings reveal that online and social media have given luxury fashion businesses the opportunity to establish a sustainable interaction with their customers and distinguish themselves from the competition. Still, the online business holds many challenges for luxury companies to overcome. This paper gives instructions as to how social media can be effectively incorporated into a luxury company.
The conventional view of the value-creation chain suggests offering high-value propositions at the product level (in terms of benefits provided by elements of the product) to attain high-value perceptions at the customer level, which should ultimately result in high-value appropriation at the firm level (i.e. relationship, volume, pricing and financial success). This study challenges this view and provides a differentiated understanding of the value creation chain. With a multi-industry sample of 339 companies and a sample of 626 customers to validate managerial assessments, the authors apply a configurational approach to identify whether and to what extent offering high-value propositions at the product level is necessary or sufficient for achieving superior value perceptions at the customer level and high-value appropriation at the firm level. Taking into account the company-internal and company-external environment of the value-creation chain, the study identifies seven value creation chain constellations.
