The field of tourism sciences is currently dealing with numerous challenges. The path to becoming an independent field; determining its position in society, politics and the scientific community as well as the current threat from fake news are at the heart of this discourse analytical essay.

„Nackte Tatsachen genügen nicht, um den Leser bis zum Schluss bei der Stange zu halten. [Auch der] Verfasser von [Fach- und] Sachtexten hat das Recht – wenn nicht gar die Pflicht –, die Wunder der Erzählkunst für sich zu erschließen, um seine Texte zu einer interessanten und vergnüglichen Lektüre zu machen.“ – Der Vortrag geht der Frage nach, ob diese Forderung des vielgelesenen Ratgeberautors Sol Stein berechtigt ist und inwiefern sie eingelöst werden kann. Zu diesem Zweck werden Stil- und Kompositionsmittel aus den Bereichen Lexik, Grammatik, Syntax, Stilistik, Erzählstrategie und Textorganisation anhand von Formulierungsbeispielen vorgestellt und auf ihre Funktion in Erzählliteratur oder Journalismus hin untersucht. In einem zweiten Schritt wird jeweils nach der Übertragbarkeit dieser sprachlichen Mittel auf Fachtexte gefragt. Anhand parallel ausgerichteter Beispiele wird eine mögliche verlagerte Funktion im Wissenschaftskontext skizziert. Der erhoffte Erkenntnisgewinn des Vortrags betrifft sowohl das Verfassen eigener Publikationen als auch die Vermittlung von Schreibfähigkeiten für künftige Fachautor*innen, weshalb die Formulierungsbeispiele verschiedensten, auch technischen und naturwissenschaftlichen Domänen entnommen sind.

Wie kann der Bedarf für berufliches Schreiben ermittelt werden und welche Schwierigkeiten sind dabei zu erwarten? Im Beitrag wird auf Erfahrungen zurückgegriffen, die in einer verwandten Disziplin gemacht wurden: Für berufsbegleitende Sprachkurse in Unternehmen liegen bereits viele Bedarfsermittlungen vor. Diese Erfahrungen können bei Bedarfsermittlungen für berufliches Schreiben berücksichtigt werden. Im Mittelpunkt des Beitrags stehen drei Bedarfsermittlungen zum Englischbedarf von Mitarbeitern internationaler Unternehmen, in denen die typische Methodik von Bedarfsermittlungen deutlich wird und typische Schwierigkeiten auftreten. Die Schwierigkeiten werden unter den Aspekten Erfahrungsdefizite, Kompetenzunterschiede und Machtgefälle zusammengefasst.

When integrating task-based learning into LSP courses, assessment procedures have to reflect the communicative goals of such tasks. However, performances on authentic and complex tasks are often difficult to score, because they involve not only specific language ability but also field specific knowledge. Moreover, the emphasis of tasks on meaning suggests that the communicative outcome should be regarded as the main criterion of success. This paper focuses on task design and scoring. It is argued that tasks have to be adapted to assessment purposes. However, to avoid a misalignment between teaching/learning and assessment, they should comprise the main features of LSP tasks in the sense of task-based language learning.

Business units are increasingly able to fuel the transformation that digitalization demands of organizations. Thereby, they can implement Shadow IT (SIT) without involving a central IT department to create flexible and innovative solutions. Self-reinforcing effects lead to an intertwinement of SIT with the organization. As a result, high complexities, redundancies, and sometimes even lock-ins occur. IT Integration suggests itself to meet these challenges. However, it can also eliminate the benefits that SIT presents. To help organizations in this area of conflict, we are conducting a literature review including a systematic search and an analysis from a systemic viewpoint using path dependency and switching costs. Our resulting conceptual framework for SIT integration drawbacks classifies the drawbacks into three dimensions. The first dimension consists of switching costs that account for the financial, procedural, and emotional drawbacks and the drawbacks from a loss of SIT benefits. The second dimension includes organizational, technical, and level-spanning criteria. The third dimension classifies the drawbacks into the global level, the local level, and the interaction between them. We contribute to the scientific discussion by introducing a systemic viewpoint to the research on shadow IT. Practitioners can use the presented criteria to collect evidence to reach an IT integration decision.

According to the World Food Organization, nearly half of all root and tuber crops worldwide are not consumed, but are lost due to inappropriate storage and post-harvest losses. In developing countries such as Ethiopia, potatoes have not been dried, but are traditionally stored in potato clamps. So far, dried potatoes have not been converted into usable foods. The aim of the present work is to convert potatoes - perishable rootlets and tubers - into stable products by hot air drying. Hot air dryers are economical to operate in industrialized countries. In Africa, this is reserved for larger industrial companies only. In regions with a tropical climate, however, the use of solar tunnel dryers is worthwhile. These are a good choice for farming and small industries and wherever electrical energy is difficult or impossible to obtain. In a first part of the work, the drying process of potatoes was investigated, in particular with regard to the change of thermal, mechanical and chemical quality parameters. In an evaluation of the literature it was found that potatoes are not subject to quality changes if the water activityis below a value of 0.2. In order to determine the water content associated with this value at storage temperature, the known equations for the sorption equilibrium were evaluated and verified with own experimental investigations. This determined the end point of the drying process. The following experimental investigations showed a process-dependent change of the quality criteria such as color, shrinkage, and mechanical properties as well as the content of valuedetermining substances such as vitamin C and starch. The differences in the course and magnitude of the quality changes were attributed to the glass transition that takes place during the drying process. For the determination of the glass transition temperature a new, simple method based on the measurement of mechanical properties could be developed. The knowledge of the glass transition temperature allowed optimizing the drying process. The drying process could be carried out in the rubbery or glassy region, depending on the expected quality changes. Thus, all information was available to produce high quality dried potatoes in an industrial process. Since the production of potato products in less industrialized regions without sufficient supply of electrical energy should be included, potatoes were dried with a solar tunnel dryer. Examination of the quality properties mentioned above confirmed the process-dependent quality changes. Finally, the dried product was ground and with the flour thus produced, wheat flour was replaced for baking bread. An evaluation of the finished bread by a panel showed that the acceptance of the bread according to the new recipe was high, also with regard to baking volume, taste, texture and color. This work shows that by drying potatoes can be transformed a well accepted, storable and easily transportable product. The risk of losses or degradation is minimized. It can be produced on an industrial as well as on farm level. If the influence of the glass transition is taken into account, it is possible to optimize the quality of the product.

Stress is becoming an important topic in modern life. The influence of stress results in a higher rate of health disorders such as burnout, heart problems, obesity, asthma, diabetes, depressions and many others. Furthermore individual’s behavior and capabilities could be directly affected leading to altered cognition, inappropriate decision making and problem solving skills. In a dynamic and unpredictable environment, such as automotive, this can result in a higher risk for accidents. Different papers faced the estimation as well as prediction of drivers’ stress level during driving. Another important question is not only the stress level of the driver himself, but also the influence on and of a group of other drivers in the near area. This paper proposes a system, which determines a group of drivers in a near area as clusters and it derives the individual stress level. This information will be analyzed to generate a stress map, which represents a graphical view about road section with a higher stress influence. Aggregated data can be used to generate navigation routes with a lower stress influence to decrease stress influenced driving as well as improve road safety.

A method is investigated by which tight bounds on the range of a multivariate rational function over a box can be computed. The approach relies on the expansion of the numerator and denominator polynomials in Bernstein polynomials. Convergence of the bounds to the range with respect to degree elevation of the Bernstein expansion, to the width of the box and to subdivision are proven and the inclusion isotonicity of the related enclosure function is shown.
