Wissenschaft in der Vertrauenskrise? : Plädoyer für eine gemeinwohlorientierte Wissenschaft

Elena Wilhelm, Carole Probst Schilter & Christian Wassmer
Fake news, Faktenignoranz und politische Unterdrückung der Zirkulation von Wissen – die Wissenschaft muss angesichts dieser Herausforderungen ihre Rolle neu definieren. Soll sie sich in die Politik einmischen und mehr Verantwortung für die Lösung gesellschaftlicher Probleme übernehmen? Wird sie glaubwürdiger, indem sie ihre Werte transparent macht? Oder sind solche Massnahmen sogar kontraproduktiv, um einem Vertrauensverlust in die Wissenschaft entgegenzuwirken? In jedem Fall sollte Wissenschaft sich dem Gemeinwohl verpflichten, öffentliche Diskurse anstoßen und zu gesellschaftlicher Orientierung...

Risks and benefits of web-based patient narratives : systematic review

Daniel Drewniak, Andrea Glässel, Martina Hodel & Nikola Biller-Andorno
Background: Patient narratives are illustrative, individual accounts of patients’ experiences with certain health conditions. Web-based patient narratives have become widely available on the internet and in social media, as part of electronically available patient decision aids or Web-based databases. In recent years, the role of patient narratives as a source of information, insight, and support for both health care users and providers has increasingly been emphasized. Although the potential impact of patient stories has high...

ICOs als Finanzierungsinstrumente : eine empirische Untersuchung

Marco Marino
Aufgrund steigender Bekanntheit der Kryptowährungen und der Tokens haben Initial Coin Offerings («ICOs») seit dem Jahr 2017 einen regelrechten Boom erlebt. Gemäss einer Studie von PricewaterhouseCoopers wurden 2017 weltweit 552 ICOs durchgeführt und ein Gesamtkapital von 7 Mrd. USD aufgenommen. Mittlerweile rücken ICOs als Finanzierungsinstrumente in den Fokus der Regulatoren. In der Schweiz hat die zuständige Finanzmarktaufsicht FINMA 2018 eine ICO-Wegleitung mit Hinweisen für die finanz-marktrechtliche Behandlung der emittierten Tokens veröffentlicht. So unterliegen Tokens, welche...

On the CSR perception of millennials : an analysis among School of Management and Law students

Selina Baumgartner
Corporate social responsibility (CSR) has become indispensable in today’s business world and is an integral part of corporate strategy to build stakeholder trust and remain competitive. One particular stakeholder group, Millennials (born 1980-2000), have either recently entered the labor market or will soon do so. Practitioners and academics have thus increased interest in how Millennials perceive CSR: Does CSR impact their buying decisions as customers, or their job decisions as potential or current employees? The...

«Performance analysis of niche alternatives and hedge fund strategies»

Atabey Kirant
The interest of institutional investors in hedge funds as alternative investments has grown substantially over the last decade. The key reason for adding alternative investments to a well-diversified institutional portfolio is the risk-return profile, which is achieved by reducing the risk through diversification and enhancing the returns through alpha. In addition to the well-known hedge fund investment strategies, the Swiss investment company Progressive Capital Partners Ltd. offers its own specialized niche alternative assets consisting of...

The role of trust within the sharing economy and how it can be increased

Pascal Rueff
Trust is seen as a prerequisite for any relationship, so it plays a crucial role in the sharing economy. Technology has made it possible for peers which have never met before to now trust each other. However, trust is still seen as a major barrier to participate in the sharing economy. Sharing economy platforms try to overcome this obstacle by so called trust-increasing measures such as ratings, reviews etc. The effectiveness of such measures has...

Differences in rhetorical and non-verbal communication of startup pitches in American and Swiss cultures

Selina Tanno
In recent years, the conventional business plan presentation has been replaced by the pitch, which has become the main method of communication towards investors for many startups. Consequently, strong presentation and communication skills are of paramount importance. Furthermore, startup founders are facing new challenges while raising funding from investors, especially when introducing their businesses into new markets. Pitching in another country without any experience is a serious problem for many startup founders. Therefore, the main...

Konzept eines Agroforstsystems auf der Parzelle Schünenacher des Birchhofs

Marc Fröhli & Philipp Fischbacher
Die vorliegende Arbeit hatte zum Ziel, den bereits bestehenden Entwurf für ein Agroforstsystem auf der Parzelle «Schünenacher» auf dem Birchhof in Oberwil-Lieli genauer zu untersuchen. Es interessierte, wie er sich in bestehende Rahmenbedingungen wie Agrarpolitik, Klimawandel und Nachhaltigkeit einfügt. Weiter wurde untersucht, weshalb das ausgearbeitete Konzept in den sensibelsten Punkten eines landwirtschaftlichen Systems (Pflanzenschutz, Düngung, Biodiversität, Bodenfruchtbarkeit, Finanzen, fossile Rohstoffe) gegenüber bestehenden Modellen besser abschneiden sollte. Nicht zuletzt wurden anhand des Praxisbeispiels Birchhof die spezifischen...

High consistency of structure-based design and x-ray crystallography : design, synthesis, kinetic evaluation and crystallographic binding mode determination of biphenyl-N-acyl-β-D-glucopyranosylamines as glycogen phosphorylase inhibitors

Thomas Fischer, Symeon M. Koulas, Anastasia S. Tsagkarakou, Efthimios Kyriakis, George A. Stravodimos, Vassiliki T. Skamnaki, Panagiota G.V. Liggri, Spyros E. Zographos, Rainer Riedl & Demetres D. Leonidas
Structure-based design and synthesis of two biphenyl-N-acyl-β-d-glucopyranosylamine derivatives as well as their assessment as inhibitors of human liver glycogen phosphorylase (hlGPa, a pharmaceutical target for type 2 diabetes) is presented. X-ray crystallography revealed the importance of structural water molecules and that the inhibitory efficacy correlates with the degree of disturbance caused by the inhibitor binding to a loop crucial for the catalytic mechanism. The in silico-derived models of the binding mode generated during the design...

Comparative genomics of Xanthomonas fragariae and Xanthomonas arboricola pv. fragariae reveals intra- and interspecies variations

Michael Gétaz, Jochen Blom, Theo H. M. Smits & Joël F. Pothier
The quarantine bacterium Xanthomonas fragariae causes angular leaf spots on strawberry. Its population structure was recently found to be divided into four (sub)groups resulting from two distinct main groups. Xanthomonas arboricola pv. fragariae causes bacterial leaf blight, but the bacterium has an unclear virulence status on strawberry. In this study, we use comparative genomics to provide an overview of the genomic variations of a set of 58 X. fragariae and five X. arboricola pv. fragariae...

Tripartite species interaction : eukarotic hosts suffer more from phage susceptible than from phage resistant bacteria

Carolin Charlotte Wendling, Agnes Piecyk, Dominik Refardt, Cynthia Maria Chibani, Robert Hertel, Heiko Liesegang, Boyke Bunk, Jörg Overmann & Olivia Roth
Background: Evolutionary shifts in bacterial virulence are often associated with a third biological player, for instance temperate phages, that can act as hyperparasites. By integrating as prophages into the bacterial genome they can contribute accessory genes, which can enhance the fitness of their prokaryotic carrier (lysogenic conversion). Hyperparasitic influence in tripartite biotic interactions has so far been largely neglected in empirical host-parasite studies due to their inherent complexity. Here we experimentally address whether bacterial resistance...

Potential of algae turf scrubbers (ATS™) for elimination of phosphorus from swimming ponds

Andreas Graber, Thomas Leiblein, Dominik Refardt & Ranka Junge
Algal Turf Scrubbers (ATS) are water treatment devices that use light and nutrients in the (waste)water to grow periphyton community; undesirable chemicals are removed by physical, chemical and biological processes. So far, most ATS systems were operated in water bodies with relatively high nutrient concentrations. Little is known about the performance of ATS under low concentration of phosphorous (P), yet there are potential applications where such conditions are met. The paper presents a series of...

Ovarian cancer in Switzerland : incidence and treatment according to hospital registry data

Simon Wieser, Marion Schmidt, André B. Kind & Viola A. Heinzelmann-Schwarz
Objective: The methods used to diagnose and classify ovarian cancer have changed over the past decade. We used hospital registry data to assess the incidence, treatment durations and hospital costs of ovarian cancer in Switzerland. Methods: We carried out a retrospective analysis of a hospital registry covering all inpatient care episodes in Switzerland between 1998 and 2012. Ovarian cancer incidence was assessed by identifying patients with a first ovarian cancer diagnosis as the main reason...

The impact of hydropower on microbial diversity and community structure in floodplains

Nadine Antenen
Within freshwater ecosystems, floodplains are among the most diverse ecosystems on earth but the increasing human demand for water, energy and food resulted in a decrease of biodiversity. Even though hydropower is often seen as “green energy”, it creates several negative impacts on riverine systems. In order to produce energy, river water is abstracted and released, leading to hydropeaking and residual flow sections, both representing a major disturbance on the natural functions and dynamics of...

Survey on evaluation methods for dialogue systems

Jan Milan Deriu, Alvaro Rodrigo, Arantxa Otegi, Guillermo Echegoyen, Sophie Rosset, Eneko Agirre & Mark Cieliebak
In this paper, we survey the methods and concepts developed for the evaluation of dialogue systems. Evaluation, in and of itself, is a crucial part during the development process. Often, dialogue systems are evaluated by means of human evaluations and questionnaires. However, this tends to be very cost- and time-intensive. Thus, much work has been put into finding methods which allow a reduction in involvement of human labour. In this survey, we present the main...

Quantitative assessment of specific defects in roasted ground coffee via infrared-photoacoustic spectroscopy

Rafael Carlos Eloy Dias, Patrícia Valderrama, Paulo Henrique Março, Maria Brigida Dos Santos Scholz, Michael Edelmann & Chahan Yeretzian
Chemical analyses and sensory evaluation are the most applied methods for quality control of roasted and ground coffee (RG). However, faster alternatives would be highly valuable. Here, we applied infrared-photoacoustic spectroscopy (FTIR-PAS) on RG powder. Mixtures of specific defective beans were blended with healthy (defect-free) Coffea arabica and Coffea canephora bases in specific ratios, forming different classes of blends. Principal Component Analysis allowed predicting the amount/fraction and nature of the defects in blends while partial...

Intervalltraining versus kontinuierliches Ausdauertraining bei Patienten und Patientinnen mit Herzinsuffizienz und reduzierter Ejektionsfraktion

Aurelia Lehmann
Hintergrund: Ausdauertraining ist bis heute die nachweislich effektivste Intervention, um die verminderte Ausdauerkapazität von Personen mit einer chronischen Herzinsuffizienz (CHF) zu verbessern und wird deshalb in sämtlichen Guidelines empfohlen. Aktuell wird sowohl in der Literatur als auch in der Praxis kontrovers diskutiert, ob das bisher primär angewendete kontinuierliche Ausdauertraining (KT) durch das von neueren Studien teilweise als effektiver postulierte Intervalltraining (IT) ersetzt werden soll. Das Ziel des vorliegenden Reviews war es, zu ermitteln, ob IT...

Exploring narrativity in data visualization in journalism

Wibke Weber
Many news stories are based on data visualization, and storytelling with data has become a buzzword in journalism. But what exactly does storytelling with data mean? When does a data visualization tell a story? And what are narrative constituents in data visualization? This chapter first defines the key terms in this context: story, narrative, narrativity, showing and telling. Then, it sheds light on the various forms of narrativity in data visualization and, based on a...
