Our corpus consists of the digitised biographical lexicon “Neue Deutsche Biographie (NDB)”, roughly 21.000 biographies in 25 volumes in print since 1953. We developed local grammars and suitable dictionaries to describe interpersonal relations and applied them to the corpus with Unitex 3.1. The local grammars were designed to integrate existing TEI-XML structures in the corpus. Using the ability of local grammars in Unitex to act as transducers we were able to produce XML-Tags and encode semantic information. Based on grammars for personal names and places we described interpersonal relations like to study, predecessors and successors as well as friends and circles. Afterwards we\r\nidentified persons (as given in the authority file or index). Finally we displayed relations on our website in an interactive and dynamic way. Utilizing the Javascript library D3.js we represented named relations between identified individuals as ego centred network graphs." author: - first_name: Sophia full_name: Stotz, Sophia last_name: Stotz - first_name: Valentina full_name: Stuß, Valentina last_name: Stuß - first_name: Matthias full_name: Reinert , Matthias last_name: 'Reinert ' - first_name: Maximilian full_name: Schrott, Maximilian last_name: Schrott citation: ama: 'Stotz S, Stuß V, Reinert M, Schrott M.

While research on IT security investment is fast growing, it lacks a theoretical basis for structuring research, explaining economic-technological phenomena and guide future research. We address this shortcoming by suggesting a new theoretical model emerging from a multi-theoretical perspective adopt-ing the Resource-Based View and the Organizational Learning Theory. The joint appli-cation of these theories allows to conceptualize in one theoretical model the organiza-tional learning effects that occur when the protection of organizational resources through IT security countermeasures develops over time. We use this model of IT security invest-ments to synthesize findings of a large body of literature and to derive research gaps. We also discuss managerial implications of (closing) these gaps by providing practical ex-amples. author: - first_name: Eva full_name: Weishäupl, Eva last_name: Weishäupl - first_name: Emrah full_name: Yasasin, Emrah last_name: Yasasin - first_name: Guido full_name: Schryen, Guido id: '72850' last_name: Schryen citation: ama: 'Weishäupl E, Yasasin E, Schryen G.

However, it is a challenging task to assign access rights to employees? accounts within a satisfying time frame. In addition, the management of multiple accounts and identities can be very onerous and time consuming for the responsible administrator and therefore expensive for the organization. In order to meet these challenges, firms decide to invest in introducing an Identity and Access Management System (IAMS) that supports the organization by using policies to assign permissions to accounts, groups, and roles. In practice, since various versions of IAMSs exist, it is a challenging task to decide upon introduction of an IAMS. The following study proposes a first attempt of a decision support model for practitioners which considers four alternatives: Introduction of an IAMS with Role-based Access Control RBAC) or without and no introduction of IAMS again with or without RBAC. To underpin the practical applicability of the proposed model, we parametrize and operationalize it based on a real world use case using input from an expert interview.' author: - first_name: Eva full_name: Weishäupl, Eva last_name: Weishäupl - first_name: Michael full_name: Kunz, Michael last_name: Kunz - first_name: Emrah full_name: Yasasin, Emrah last_name: Yasasin - first_name: Gerit full_name: Wagner, Gerit last_name: Wagner - first_name: Julian full_name: Prester, Julian last_name: Prester - first_name: Guido full_name: Schryen, Guido id: '72850' last_name: Schryen - first_name: Günther full_name: Pernul, Günther last_name: Pernul citation: ama: 'Weishäupl E, Kunz M, Yasasin E, et al.

Yet, we observe a lack of theoretical underpinning of and epistemological insights into how literature reviews can contribute to knowledge creation and have actually contributed in the IS discipline. To address these theoretical and empirical research gaps, we suggest a novel epistemological model of literature reviews. This model allows us to align different contributions of literature reviews with their underlying knowledge conversions - thereby building a bridge between the previously largely unconnected fields of literature reviews and epistemology. We evaluate the appropriateness of the model by conducting an empirical analysis of 173 IS literature reviews which were published in 39 pertinent IS journals between 2000 and 2014. Based on this analysis, we derive an epistemological taxonomy of IS literature reviews, which complements previously suggested typologies. author: - first_name: Guido full_name: Schryen, Guido id: '72850' last_name: Schryen - first_name: Gerit full_name: Wagner, Gerit last_name: Wagner - first_name: Alexander full_name: Benlian, Alexander last_name: Benlian citation: ama: 'Schryen G, Wagner G, Benlian A.

We enumerate all orthogonal spaces (V,Q) of dimension at least 3, where the corresponding genus of maximal integral lattices consists of a single isometry class. It turns out, there are 471 such genera. Moreover, the dimension of V and the degree of K are bounded by 6 and 5 respectively.

The questionnaire is designed to measure students' attitudes towards two particular objects: the university (or Higher Education Institution) and the process of studying. Five studies at two different universities were conducted to develop and validate the Attitudes towards the Study Environment Questionnaire (ASEQ). In total, 1640 students filled in the questionnaire. Reliability tests and exploratory factor analysis as well as confirmatory factor analysis showed satisfactory psychometric characteristics of the ASEQ. Each part of the questionnaire is internally consistent and construct validity of the scales is supported by correlations with other constructs as assumed by current theories: Positive attitudinal constructs (normative behavior, autonomy, joy, self-efficacy, and task value) are positively related to intrinsic motivation and the expected study performance while anxiety is negatively related to these constructs. \r\nSince attitudes towards the study situation are connected to student engagement and motivation, the study contributes to the theory of student learning by providing a validated instrument to assess attitudes. Thus, the ASEQ can support further research on student performance and development by providing an instrument for the hitherto neglected but nonetheless extremely relevant domain of attitudes. Also, the questionnaire can be used as a diagnostic instrument for higher education faculty and administration to trace students' attitudinal development over time - a factor of prime importance for student socialization during the introductory phase of studying." author: - first_name: Taiga full_name: Brahm, Taiga last_name: Brahm - first_name: Tobias full_name: Jenert, Tobias id: '71994' last_name: Jenert orcid: ' https://orcid.org/0000-0001-9262-5646' - first_name: Dieter full_name: Euler, Dieter last_name: Euler citation: ama: 'Brahm T, Jenert T, Euler D.

Zur Beantwortung dieser Fragen wurde über das erste Studienjahr hinweg eine Interviewserie mit 13 Studierenden durchgeführt.

To this end, the SPP estimation is formulated as the posterior probability estimation of the states of a two-dimensional (2D) Hidden Markov Model (HMM). We derive an iterative algorithm to decode the 2D-HMM which is based on the turbo principle. The experimental results show that indeed the SPP estimates improve from iteration to iteration, and further clearly outperform another state-of-the-art SPP estimation algorithm. author: - first_name: Dang Hai Tran full_name: Vu, Dang Hai Tran last_name: Vu - first_name: Reinhold full_name: Haeb-Umbach, Reinhold id: '242' last_name: Haeb-Umbach citation: ama: 'Vu DHT, Haeb-Umbach R.

${F}_{BC} (\lambda , k; t)$

be the Heckman–Opdam hypergeometric function of type BC with multiplicities

$k= ({k}_{1} , {k}_{2} , {k}_{3} )$

and weighted half-sum

$\rho (k)$

of positive roots. We prove that

${F}_{BC} (\lambda + \rho (k), k; t)$

converges as

${k}_{1} + {k}_{2} \rightarrow \infty $

and

${k}_{1} / {k}_{2} \rightarrow \infty $

to a function of type A for

$t\in { \mathbb{R} }^{n} $

and

$\lambda \in { \mathbb{C} }^{n} $

. This limit is obtained from a corresponding result for Jacobi polynomials of type BC, which is proven for a slightly more general limit behavior of the multiplicities, using an explicit representation of Jacobi polynomials in terms of Jack polynomials. Our limits include limit transitions for the spherical functions of non-compact Grassmann manifolds over one of the fields

$ \mathbb{F} = \mathbb{R} , \mathbb{C} , \mathbb{H} $

when the rank is fixed and the dimension tends to infinity. The limit functions turn out to be exactly the spherical functions of the corresponding infinite-dimensional Grassmann manifold in the sense of Olshanski. author: - first_name: Margit full_name: Rösler, Margit id: '37390' last_name: Rösler - first_name: Tom full_name: Koornwinder, Tom last_name: Koornwinder - first_name: Michael full_name: Voit, Michael last_name: Voit citation: ama: Rösler M, Koornwinder T, Voit M.
