The main objective of this thesis is to bridge the gap between modeling method experts on the one side and tool developers on the other. More precisely, the focus is on the specification of requirements for multi-view modeling tools. In this regard, the thesis introduces a methodological approach that supports the specification of conceptual designs for multi-view modeling tools in a stepwise manner: the MuVieMoT approach. MuVieMoT utilizes generic multi-view modeling concepts and the model-driven engineering paradigm to establish an overarching specification of multi-view modeling tools with an emphasis on consistency requirements. The approach builds on and extends the theoretical foundation of metamodeling and multi-view modeling: generic multi-view modeling concepts, integrated multi-view modeling approaches, and possibilities for formalized modeling method specifications. Applicability and utility of MuVieMoT are evaluated using an illustrative scenario, therefore specifying a conceptual design for a multi-view modeling tool for the Semantic Object Model enterprise modeling method. The thesis moreover introduces the MuVieMoT modeling environment, enabling the efficient application of the approach as well as the model-driven development of initial multi-view modeling tools based on the conceptual models created with MuVieMoT. Consequently, the approach fosters an intersubjective and unambiguous understanding of the tool requirements between method experts and tool developers.
An airport is the gateway which facilitates access to air transport. As a reaction to very diverse attacks on the air transport system during the last decades a broad range of security measures has been introduced to mitigate possible threats. The challenge to provide a trouble free experience for the passenger and, at the same time, to oper-ate more efficiently calls for a proactive approach. This requires the definition of future requirements that allow an adaptation of the security system. When dealing with uncertainty that future-oriented decisions inevitably display, it is important to gain as much knowledge as possible about a system’s general structure. The approach described in this paper systematically documents elements and relationships of the airport security system. It consists of threat scenario elements as well as security measures. The development of a software tool, the so-called Scenario Builder, is described and its application for the identification of possible future threats ex-plained. The presented approach offers intuitive access to the underlying structure of the airport security system. It provides decision makers with a possibility to interact with the system and anticipate effects of threat development, thereby enabling robust, future-oriented decisions.
The second album on "Slavic Alphabet tables" presents more than 60 additional sources: grammars and primers from Slavic countries (mainly Russia and Bulgaria, to a lesser degree Serbia), manuals on Old Church Slavonic, and several Western sources. It complements the first volume which was devoted to typographical works of Western origin.
Becoming a parent is a major, privotal life course event (Galdiolo& Roskam, 2012). While many people desire having children, research on parenthood and life satisfaction suggests that the emotional benefits of parenthood are outweighed by time, psychosocial stress and financial costs (Polmann-Schult, 2014). It has been suggested that parenthood has a more negative effect on life satisfaction for women as compared to men (Hansen, 2012). The aim of the current study is to extend findings regarding gender and life satisfaction across Transition to parenthood, by looking at changes in satisfaction in various life domains across a 4-year time period.
Past research has found that the well-being of singles who desire a romantic relationship ("singles by circumstance") is poorer than that of singles who choose to remain single, in terms of loneliness, depression and self-esteem (Slonim& Schütz, 2015). Therefore, it is important to understand why some singles are satisfied with their relationship status while others are highly motivated to change it. Could it be that the two groups of singles differ regarding their expectations from romantic relationships?
Past research has found substantial differences between cuopled individuals and groups of singles in terms of their perceptions of the costs and benefits of romantic relationships (Slonim& Schütz, 2015). Coupled people see more benefits and less costs in romantic relationships, while singles, especially those who are currently not looking for a relationship, perceive romantic relationships as more costly and less beneficial. We investigated whether the three groups (coupled individuals, singles by choice and singles by circumstance) also differ in terms of their perceptions of the costs and benefits of having children. We had two competing hypothesis: on the one hand, singles by choice may value having freedom and so they will try to avoid what might limit their independence. Therefore they may perceive having children as less beneficial and more costly, similar to their attitudes towards being part of a romantic couple. On the other hand, it is possible that the differences between the groups are small (if any), since wanting children and wanting a partner no longer necessarily have to be related to each other. In the past, people who wanted children had to first find a romantic partner. However, nowadays, advances in medicine offer various ways to become a parent - even without the need to have sex. In addition, sociological changes made non-traditional households and lifestyles, such as being a single parent, more acceptable (Lamana, Riedmann& Stewart, 2015).
This PhD thesis investigates the relationship between corporate IT capability and institutional investors from two different perspectives. From the first perspective, institutional investors influence companies in their strategies and objectives. From the second, IT capability has considerable firm-internal implications that increase future prospects and firm value, which in turn attracts certain investors. The empirical results illustrate significant differences in ownership structure for firms characterized by superior IT capability. Looking deeper into this phenomenon indicates that the development of a firm’s IT capability is related to subsequent changes in the ownership structure towards more long-term oriented institutional shareholders and vice versa. This dissertation contributes to the understanding of the firm-external influences of institutional investors as well as the capital market implications of firms’ IT capability.
The eponymous heroes of "Strange Case of Dr Jekyll and Mr Hyde", "The Picture of Dorian Gray" and "Dracula" are known to most through the medium of film. These novels were adapted early on in the history of the medium and have been revisited by film makers countless times. This book asks why they had such a lasting resonance in film. It claims that the monsters featured in these novels, which were written at the advent of cinematography, differ from previous Gothic leads: Jekyll/Hyde, Dorian Gray and Dracula were born from a sense of unease with the photographic image at a time when it began to move. They embody fears triggered by new ways of representing – and thus thinking about – the human body. Their exhibitions of deviant corporeality and its effect on others anticipate the representation of the human body in film as well as an audience’s reception of a film.
Through its numerous case studies, this monograph is able to show that film history can be told as a history of the representation of the human body. It features discussions of films as diverse as "Der Januskopf", "Nosferatu", "Vampyr", "Le Testament du Docteur Cordelier", "Altered States", "Dorian Gray im Spiegel der Boulevardpresse" and "Bram Stoker’s Dracula".
Arguably, the current interest in the complexity sciences has its roots in the natural sciences, often in interplay with, and enhanced by, developments in mathematics and informatics. An oft-cited reason for this interest has been the increased ability of current computing systems to deal with complex mathematics and algorithms. As complexity gains more traction in the natural sciences, so it does in the social sciences (see e.g. Castellani, 2009). Naturally, complexity has also invaded the evaluation literature since the 1990s, where it is increasingly discussed and applied (cf. Walton, 2014). For instance, the journal Evaluation has recently published a steady number of complexity-related pieces. A search within the journal on the terms ‘complexity theory’, ‘complex system’ or ‘complexity science’ yielded forty-nine articles as part of an increasing trend. Inquiries with Scopus into complexity and evaluation yielded similar results. In this article, we take stock of recent progress and discuss what complexity holds for evaluation by discussing three recent books.
We submitted three models to the competition which were based on the I-SAW model. The models introduced four new assumptions. In the first model an adjustment process was introduced through which the tendency for exploration was higher at the beginning and decreased over time in the exploration stage. Another new assumption was that surprise as a factor influencing the weight of a trial in the sampling procedure was added. In the second model we added the possibility of an exclusion of unreliable experiences gained in the early trials of a game and the possibility of a revision of a reasonable alternative which was responsible for a very bad outcome in the previous trial. Three of the four added assumptions were combined in the third model. Because each of our models contains at least two new assumptions, we estimated the relative effect of each assumption on the estimation and prediction scores and carried out a test of robustness. In this way, we were able to clarify the usefulness of each added assumption.
