Applicability of Process Mining Techniques in Business Environments

This thesis analyses problems related to the applicability, in business environments, of Process Mining tools and techniques. The first contribution is a presentation of the state of the art of Process Mining and a characterization of companies, in terms of their "process awareness". The work continues identifying circumstance where problems can emerge: data preparation; actual mining; and results interpretation. Other problems are the configuration of parameters by not-expert users and computational complexity. We concentrate on two possible scenarios: "batch" and "on-line" Process Mining. Concerning the batch Process Mining, we first investigated the data preparation problem and we proposed a solution for the identification of the "case-ids" whenever this field is not explicitly indicated. After that, we concentrated on problems at mining time and we propose the generalization of a well-known control-flow discovery algorithm in order to exploit non instantaneous events. The usage of interval-based recording leads to an important improvement of performance. Later on, we report our work on the parameters configuration for not-expert users. We present two approaches to select the "best" parameters configuration: one is completely autonomous; the other requires human interaction to navigate a hierarchy of candidate models. Concerning the data interpretation and results evaluation, we propose two metrics: a model-to-model and a model-to-log. Finally, we present an automatic approach for the extension of a control-flow model with social information, in order to simplify the analysis of these perspectives. The second part of this thesis deals with control-flow discovery algorithms in on-line settings. We propose a formal definition of the problem, and two baseline approaches. The actual mining algorithms proposed are two: the first is the adaptation, to the control-flow discovery problem, of a frequency counting algorithm; the second constitutes a framework of models which can be used for different kinds of streams (stationary versus evolving).

Understanding the Combined Role of Internal and External Factors in New Service Development Process within the Professional Knowledge Intensive Business Service Firms

Our research asked the following main questions: how the characteristics of professionals service firms allow them to successfully innovate in exploiting through exploring by combining internal and external factors of innovation and how these ambidextrous organisations perceive these factors; and how do successful innovators in professional service firms use corporate entrepreneurship models in their new service development processes? With a goal to shed light on innovation in professional knowledge intensive business service firms’ (PKIBS), we concluded a qualitative analysis of ten globally acting law firms, providing business legal services. We analyse the internal and factors of innovation that are critical for PKIBS’ innovation. We suggest how these firms become ambidextrous in changing environment. Our findings show that this kind of firms has particular type of ambidexterity due to their specific characteristics. As PKIBS are very dependant on its human capital, governance structure, and the high expectations of their clients, their ambidexterity is structural, but also contextual at the same time. In addition, we suggest 3 types of corporate entrepreneurship models that international PKIBS use to enhance innovation in turbulent environments. We looked at how law firms going through turbulent environments were using corporate entrepreneurship activities as a part of their strategies to be more innovative. Using visual mapping methodology, we developed three types of innovation patterns in the law firms. We suggest that corporate entrepreneurship models depend on successful application of mainly three elements: who participates in corporate entrepreneurship initiatives; what are the formal processes that enhances these initiatives; and what are the policies applied to this type of behaviour.

Aging and Mental Health: Business as Usual?

Cautions that in developing training models in mental health and aging, psychologists must not overlook what experience has taught them about mental health intervention or what they know already about older adults. It is suggested that a life-span developmental view complements a community and preventive approach to the mental health needs of the elderly. Creation of a separate subspecialty of clinical geropsychology will not effectively serve older adults. What is needed is a synthesis ofalready existing expertise in areas such as life-span development, clinical psychology, and community psychology. This synthesis provides a conceptual foundation and set of intervention approaches on which to base training programs in mental health and aging.

Incorporating Latent Variables into Discrete Choice Models - A Simultaneous Estimation Approach Using SEM Software

Integrated choice and latent variable (ICLV) models represent a promising new class of models which merge classic choice models with the structural equation approach (SEM) for latent variables. Despite their conceptual appeal, applications of ICLV models in marketing remain rare. We extend previous ICLV applications by first estimating a multinomial choice model and, second, by estimating hierarchical relations between latent variables. An empirical study on travel mode choice clearly demonstrates the value of ICLV models to enhance the understanding of choice processes. In addition to the usually studied directly observable variables such as travel time, we show how abstract motivations such as power and hedonism as well as attitudes such as a desire for flexibility impact on travel mode choice. Furthermore, we show that it is possible to estimate such a complex ICLV model with the widely available structural equation modeling package Mplus. This finding is likely to encourage more widespread application of this appealing model class in the marketing field.

Generalizability and Applicability of Model-Based Business Process Compliance-Checking Approaches – A State-of-the-Art Analysis and Research Roadmap

With a steady increase of regulatory requirements for business processes, automation support of compliance management is a field garnering increasing attention in Information Systems research. Several approaches have been developed to support compliance checking of process models. One major challenge for such approaches is their ability to handle different modeling techniques and compliance rules in order to enable widespread adoption and application. Applying a structured literature search strategy, we reflect and discuss compliance-checking approaches in order to provide an insight into their generalizability and evaluation. The results imply that current approaches mainly focus on special modeling techniques and/or a restricted set of types of compliance rules. Most approaches abstain from real-world evaluation which raises the question of their practical applicability. Referring to the search results, we propose a roadmap for further research in model-based business process compliance checking.

Family models of independence/interdependence and their intergenerational similarity in Germany, Turkey, and India

Family change theory suggests three ideal-typical family models characterized by different combinations of emotional and material interdependencies in the family. Its major proposition is that in economically developing countries with a collectivistic background a family model of emotional interdependence emerges from a family model of complete interdependence. The current study aims to identify and compare patterns of family-related value orientations related to family change theory across three cultures and two generations. Overall, N = 919 dyads of mothers and their adolescent children from Germany, Turkey, and India participated in the study. Three clusters were identified representing the family models of independence, interdependence, and emotional interdependence, respectively. Especially the identification of an emotionally interdependent value pattern using a person-oriented approach is an important step in the empirical validation of family change theory. The preference for the three family models differed across as well as within cultures and generations according to theoretical predictions. Dyadic analyses pointed to substantial intergenerational similarities and also to differences in family models, reflecting both cultural continuity as well as change in family-related value orientations.

Adolescents' family models: A cross-cultural study

Die vorliegende kulturvergleichende Arbeit befasst sich mit den Familienmodellen Jugendlicher in zehn Kulturen auf Basis eines typologischen Ansatzes und eines Mehrebenenansatzes. Sie leistet damit einen empirischen Beitrag zur Theorie der Familienmodelle im kulturellen Wandel nach Kagitcibasi (2007). Diese Theorie postuliert die Existenz dreier idealtypischer Familienmodelle: ein Familienmodell der Independenz, das in industrialisierten westlichen Gesellschaften vorherrscht, ein Familienmodell der (vollständigen) Interdependenz, das in nicht-industrialisierten agrarischen Kulturen zu finden ist, und als Synthese aus den beiden genannten ein Familienmodell der emotionalen Interdependenz. Letzteres entwickelt sich der Theorie zufolge, wenn nicht-industrialisierte kollektivistische Kulturen Modernisierungsprozessen ausgesetzt sind. Traditionelle Kulturen mit einem Familienmodell der (vollständigen) Interdependenz sollen sich also im Zuge gesellschaftlicher Modernisierungsprozesse nicht notwendigerweise hin zum Familienmodell der Independenz entwickeln, sondern zu einem emotional-interdependenten Modell, das erlaubt, Autonomie mit enger interpersoneller Verbundenheit zu vereinen. Diese Annahme steht im Widerspruch zu klassischen modernisierungstheoretischen Annahmen und wurde in bisherigen Studien nur unzureichend geprüft. In einem typologischen Mehrebenen-Ansatz sollen Profile allgemeiner und familienbezogener Werthaltungen Jugendlicher identifiziert werden, die mit den drei idealtypischen Familienmodellen theoretisch verbunden werden können. In einem zweiten Schritt sollen diese Wertemuster durch verhaltensnähere Familienmodellindikatoren validiert werden. Die Daten für diese Arbeit stammen aus der von der Deutschen Forschungsgemeinschaft geförderten kulturvergleichenden und interdisziplinären Value of Children and Intergenerational Relations Studie (Trommsdorff, 2001) und umfassen eine Stichprobe von 2566 Jugendlichen aus der Volksrepublik China, Deutschland, Frankreich, Indien, Indonesien, Israel, Japan, Südafrika, der Schweiz und der Türkei. Zur Identifikation der angenommen Familienmodell-Werteprofile wurden Cluster-Analysen auf der Kultur- und auf der Individualebene durchgeführt. Auf beiden Analyseebenen zeigten sich drei Werteprofile, die dem erwarteten Muster der drei idealtypischen Familienmodelle entsprachen. Das Familienmodell der emotionalen Interdependenz zeigte dabei bezüglich der Werthaltungen, die emotionale Interdependenzen in der Familie widerspiegeln ähnlich hohe Werte wie das Familienmodell der (vollständigen) Interdependenz, dagegen zeigte es ähnliche Werte wie das Familienmodell der Independenz in Bezug auf Autonomie und materielle Interdependenz widerspiegelnde Werte. In Kulturen, die auf der Kulturebene ein bestimmtes Familienmodell-Werteprofil aufwiesen befanden sich zudem überwiegend Jugendliche, die das jeweils korrespondierende Werteprofil auf der individuellen Analyseebene aufzeigten. Zur Validierung der erhaltenen Familienmodell-Werteprofile wurden diese zu verhaltensnäheren Merkmalen von Familienmodellen in Beziehung gesetzt. Die Vorhersage erfolgte auch hier jeweils getrennt für die Kultur- und Individualebene. Mit Hilfe multinomialer logistischer Modelle wurde zunächst der Effekt der Familienmodell-Werteprofile auf die Bereitschaft der Jugendlichen überprüft, ihren Eltern bei der Hausarbeit zu helfen. Die Ergebnisse zeigten einen starken Effekt der Familienmodell-Werteprofile auf beiden Analyseebenen: fast alle Jugendlichen mit einem Familienmodell der (vollständigen) Interdependenz würden ihren Eltern helfen statt sich wie geplant mit ihren Freunden zu treffen, wohingegen nur zwei Drittel bzw. nur ein Drittel der Jugendlichen mit einem Familienmodell der emotionalen Interdependenz bzw. der Independenz der Bitte der Eltern folgen würde. In Bezug auf die familienbezogenen Zukunftsorientierungen Jugendlicher zeigte sich für die Pläne für eine zukünftige Heirat/Beziehung, dass Jugendliche mit einem Familienmodell der (vollständigen) Interdependenz den stärksten Heiratswunsch hatten. Jugendliche mit einem Familienmodell der emotionalen Interdependenz waren bezüglich dieser Frage am unsichersten, und Jugendliche mit einem Familienmodell der Independenz äußerten die stärkste Ablehnung in dieser Frage. In Bezug auf Pläne, später eigene Kinder zu haben zeigten sich ähnliche Effekte, die aber insgesamt schwächer ausfielen. Insgesamt zeigte sich trotz der Unterschiede eine hohe familienbezogene Zukunftsorientierung in allen Familienmodell-Werteprofilen sowie in allen Kulturen. Bezüglich der Sohn- bzw. Tochterpräferenz zeigten sich keine Effekte der Familienmodell- und Kulturzugehörigkeit. Die Ergebnisse der Studie stärken die umstrittene Validität insbesondere des Familienmodells der emotionalen Interdependenz. Ob es sich hierbei im Sinne der Theorie von Kagitcibasi um ein synthetisches Konvergenzmodell oder eher um ein Übergangsmodell handelt, muss zukünftige Forschung zeigen.

Values of children and family models of adolescents: An eleven-culture study

Starting from Kagitcibasi's (2007) conceptualization of family models, this study compared N = 2961 adolescents' values across eleven cultures and explored whether patterns of values were related to the three proposed family models through cluster analyses. Three clusters with value profiles corresponding to the family models of interdependence, emotional interdependence, and independence were identified on the cultural as well as on the individual level. Furthermore, individual-level clusters corresponded to culture-level clusters in terms of individual cluster membership. The results largely support Kagitcibasi's proposition of changing family models and demonstrate their representation as individual-level value profiles across cultures.

Higher emotional distress in female partners of cancer patients: prevalence and patient-partner interdependencies in a 3-year cohort

OBJECTIVE: Assessment and treatment of psychological distress in cancer patients was recognized as a major challenge. The role of spouses, caregivers, and significant others became of salient importance not only because of their supportive functions but also in respect to their own burden. The purpose of this study was to assess the amount of distress in a mixed sample of cancer patients and their partners and to explore the dyadic interdependence. METHODS: An initial sample of 154 dyads was recruited, and distress questionnaires (Hospital Anxiety and Depression Scale, Symptom Checklist 9-Item Short Version and 12-Item Short Form Health Survey) were assessed over four time points. Linear mixed models and actor-partner interdependence models were applied. RESULTS: A significant proportion of patients and their partners (up to 40%) reported high levels of anxiety, depression, psychological distress, and low quality of life over the course of the investigation. Mixed model analyses revealed that higher risks for clinical relevant anxiety and depression in couples exist for female patients and especially for female partners. Although psychological strain decreased over time, the risk for elevated distress in female partners remained. Modeling patient-partner interdependence over time stratified by patients' gender revealed specific effects: a moderate correlation between distress in patients and partners, and a transmission of distress from male patients to their female partners. CONCLUSIONS: Our findings provide empirical support for gender-specific transmission of distress in dyads coping with cancer. This should be considered as an important starting point for planning systemic psycho-oncological interventions and conceptualizing further research.

The Changing Environment of Audiovisual Media. New Technologies, New Patterns of Consumer/Business Behaviour and Their Implications for Audiovisual Media Regulation

Digital TV offers of 200 channels and 500 video-on-demand films, podcasting, mobile television, a new web blog being created every two seconds - these are some of the factual elements depicting contemporary audiovisual media in the digital environment. The present article looks into some of these technological advances and sketches their implications for the markets of media content, in particular as newly emerging patterns of consumer and business behaviour are concerned. Ultimately, it puts forward the question of whether the existing audiovisual media regulatory models, which are still predominantly analogue-based, have been rendered obsolete by the transformed (and continually transforming) digital environment.

An electrophysiological investigation of emotional change: preliminary data

Many psychotherapy researchers agree that emotional change is critical to therapeutic progress. In emotion-focused and Gestalt therapy, one technique to foster emotional change is the empty chair dialogue. Psychotherapy research has yielded ample evidence that this technique helps to alleviate longstanding interpersonal grievances (‘unfinished business’) and facilitates emotional change. Until now, little is known about the neurophysiological correlates of such emotional change. The present study thus aims at adding a further level of analysis to psychotherapy research, and may enrich knowledge about mechanisms of change. Neurophysiological correlates of emotional change were investigated using multi-channel electroencephalography. Individuals experiencing ‘unfinished business’ were guided by experienced therapists to participate in an empty chair dialogue. Event-related brain potentials were recorded before and after the intervention while participants were viewing pictures of the person central to their interpersonal grievance as well as pictures of control persons. Event related potentials are compared regarding topography and overall signal strength. Preliminary results will be discussed regarding neurophysiological mechanisms of action potentially occurring during emotional change.

Information Technology Outsourcing: Towards Sustainable Business Value

This book attempts to synthesize research that contributes to a better understanding of how to reach sustainable business value through information systems (IS) outsourcing. Important topics in this realm are how IS outsourcing can contribute to innovation, how it can be dynamically governed, how to cope with its increasing complexity through multi-vendor arrangements, how service quality standards can be met, how corporate social responsibility can be upheld, and how to cope with increasing demands of internationalization and new sourcing models, such as crowdsourcing and platform-based cooperation. These issues are viewed from either the client or vendor perspective, or both. The book should be of interest to all academics and students in the fields of Information Systems, Management, and Organization as well as corporate executives and professionals who seek a more profound analysis and understanding of the underlying factors and mechanisms of outsourcing.

The Serious Business of Play

Most managers see strategy development as serious business. It is ironic, then, that some of the most remarkable strategic breakthroughs in organizations emerge not from well-ordered processes but from messy, ambiguous and sometimes irrational activities - pursuits that can best be described as play. Referring to research in the fields of developmental psychology and anthropology, the authors argue that play can stimulate the development of cognitive, interpretive skills and engender an emotional sense of fulfillment. It can help establish a safe environment for introducing new ideas about market opportunities, generating debate about important strategic issues, challenging old assumptions and building a sense of common purpose. The authors draw on their own experiences working with managers at the Imagination Lab Foundation and Templeton College, Oxford University, and they make sure to point out that play is no substitute for rational, conventional strategy development. Indeed, after the creative sessions are over, plenty of hard work remains to translate the ideas and insights into processes and actions.

Performance Evaluation of the New Connecticut Leading Employment Index Using Lead Profiles and BVAR Models

Dua and Miller (1996) created leading and coincident employment indexes for the state of Connecticut, following Moore's (1981) work at the national level. The performance of the Dua-Miller indexes following the recession of the early 1990s fell short of expectations. This paper performs two tasks. First, it describes the process of revising the Connecticut Coincident and Leading Employment Indexes. Second, it analyzes the statistical properties and performance of the new indexes by comparing the lead profiles of the new and old indexes as well as their out-of-sample forecasting performance, using the Bayesian Vector Autoregressive (BVAR) method. The new indexes show improved performance in dating employment cycle chronologies. The lead profile test demonstrates that superiority in a rigorous, non-parametric statistic fashion. The mixed evidence on the BVAR forecasting experiments illustrates the truth in the Granger and Newbold (1986) caution that leading indexes properly predict cycle turning points and do not necessarily provide accurate forecasts except at turning points, a view that our results support.
