Using Optical Satellite Imagery to Monitor and Understand Agricultural Land-cover Change
The activities of humans have transformed the earth over the last decades. The transformation is estimated to increase further in response to the growing world population. This has caused many countries to devise means to utilize resources sustainably. Bio-economy is seen as a means to reduce the high reliance on fossil materials and ensure the provision of raw materials, energy and food to the increasing world population in a sustainable manner. However, the rising demands for biomass to produce bioenergy have relied ...
An Overview of Modeling Concepts for Service-Based Software Architectures
This document provides an overview of modeling concepts for service-based software architectures (SBSAs). The concepts were extracted during a survey of conceptual frameworks for architecture modeling of SBSAs.
Accelerating Entrepreneurial Decision-Making Through Hybrid Intelligence
Purpose: Previous studies revealed that around 75 percent of all start-ups fail at an early stage. One main reason for this tremendous failure rate is that entrepreneurs are typically confronted with high levels of uncertainty about the viability of their proposed business idea. Following this argumentation, entrepreneurial decision-making can be defined as complex decision-making problem under both risk and uncertainty. While risk includes quantifiable probabilities, uncertainty describes situations where neither ...
Same Same But Different? A Two-Foci Perspective on Trust in Information Systems
Trust is one of the most important factors driving the adoption and use of information systems. The goal of this paper is to provide a first evaluation of a conceptual piece claiming a) that users distinguish between their trust in an IS and the provider of this IS and b) that both kinds of trust are important for the success sustainable success of IS providers. To evaluate the claims, a research model is developed and evaluated using data of 234 students during the introduction of a new IS at an European university. ...
Analyzing Given Names
Computer science has evolved so much that it influences almost every part of human live. A particularly personal part of human live is the selection of a given name for a newborn baby. The name discovery service Nameling is our way to help expectant parents with this decision. It is a web service that helps parents to find a given name for their newborn baby. We want to further improve the user experience of Nameling by personalizing its name results for the current user. We deem this important, because the selection ...
Unleashing the Potential of Conversational Agents for Course Evaluations: Empirical Insights from a Comparison with Web Surveys
(Association for Information Systems, 2020)
Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. However, little is known about how these interfaces change the way users respond in online course evaluations. We aim to explore the effects of conversational agents (CAs) on the response quality of online course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor ...
The aim of this dissertation is to explore the innovation potential of crowdsourcing for entrepreneurship. The main focus is to discover how crowd-based infrastructures (i. e., crowdsourcing platforms and crowdfunding platforms) can support entrepreneurs in their innovation activities and how this new paradigm can be used to generate value for customers as well as actors of entrepreneurial ecosystems. The results of the dissertation show that crowdsourcing offers numerous opportunities to support entrepreneurs in ...
A Conversational Agent to Improve Response Quality in Course Evaluations
(Association for Computing Machinery, 2020)
Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. We hypothesize that these interfaces can interactively engage students to increase response quality of course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor response quality caused by inattention, survey fatigue or satisficing behavior. To test if conversational ...
Towards a Technique for Modeling New Forms of Collaborative Work Practices – The Facilitation Process Model 2.0
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2020)
Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary ...
Model-driven Development of Microservice Architecture: An Experiment on the Quality in Use of a UML- and a DSL-based Approach
Microservice Architecture denotes a software architectural style for service-based software systems whereby business capabilities are encapsulated in autonomously developable and deployable services. To foster a more efficient development it is considered feasible to apply the means of Model-driven Development in order to handle the complexity of such a distributed system and avoid the manual creation of boilerplate code using code generation. In this paper, we present and evaluate two modeling approaches for ...
