  text: Historically, the field of financial forecasting almost exclusively relied
    on so-called hard information – i.e., numerical data with well-defined and unambiguous
    meaning. Over the last few decades, however, researchers and practitioners alike
    have, following the advances in natural language understanding, started recognizing
    the benefits of integrating soft information into financial modelling. In line
    with the above, this paper examines whether contemporary attention-based sequence-to-sequence
    models, known as Transformers, can help improve stock return volatility prediction
    when applied to corporate annual reports. Using a publicly available benchmark
    dataset, we show, in an empirical analysis, that out-of-the-box Transformer models
    have the ability to outmatch current state-of-the-art results and, more importantly,
    that our proposed feature-based Transformer approach can outperform a robust numerical
    baseline. To the best of our knowledge, this is the first empirical study focusing
    on stock return volatility prediction (1) to ever experiment with state-of-the-art
    Transformer architectures and (2) to demonstrate that a model based solely on
    soft information can surpass its numerical counterpart. Furthermore, we show that
    by including an additional numerical feature into our best text-only model, we
    can push the performance of our model even further, suggesting that soft and hard
    information contain different predictive signals.

  text: Augmented Reality (AR) technologies have evolved rapidly over the last years,
    particularly with regard to user interfaces, input devices, and cameras used in
    mobile devices for object and gesture recognition. While early AR systems relied
    on pre-defined trigger images or QR code markers, modern AR applications leverage
    machine learning techniques to identify objects in their physical environments.
    So far, only few empirical studies have investigated AR's potential for supporting
    learning and task assistance using such marker-less AR. In order to address this
    research gap, we implemented an AR application (app)with the aim to analyze the
    effectiveness of marker-less AR applied in a mundane setting which can be used
    for on-the-job training and more formal educational settings. The results of our
    laboratory experiment show that while participants working with AR needed significantly
    more time to fulfill the given task, the participants who were supported by AR
    learned significantly more.

  text: In reaction to the productivity challenges that hospitals around the world
    have faced, some hospitals have begun to move towards a process-oriented organization
    of care in order to enhance productivity. Existing research on process-oriented
    organization emphasizes severe challenges along the implementation process. However,
    the literature contains only a small number of documented cases of hospital-wide
    process-oriented reorganization. Against this background, in this case study,
    we explain how hospitals can successfully implement organization-wide process
    orientation. To do so, we conducted an exploratory single case study with semi-structured,
    face-to-face interviews and document analyses as our primary data-collection methods.
    We developed a theoretical framework of antecedents, interventions, enablers,
    barriers, and consequences that explain the trajectory of this successful hospital-reorganization
    project. We contribute a substantive theory on which other researchers can build
    and can extend in future studies. Further, in analyzing our unique case, we identify
    factors that the extant literature has not yet discussed, such as the blackboxing
    of diagnosis and treatment activities as an enabler. In line with existing literature,
    we also found that, even in this case, inflexible healthcare IT represented a
    barrier that hindered the case study in implementing process orientation.

  text: Data-driven decision making (DDD) refers to organizational decision-making
    practices that emphasize the use of data and statistical analysis instead of relying
    on human judgment only. Various empirical studies provide evidence for the value
    of DDD, both on individual decision maker level and the organizational level.
    Yet, the path from data to value is not always an easy one and various organizational
    and psychological factors mediate and moderate the translation of data-driven
    insights into better decisions and, subsequently, effective business actions.
    The current body of academic literature on DDD lacks prescriptive knowledge on
    how to successfully employ DDD in complex organizational settings. Against this
    background, this paper reports on an action design research study aimed at designing
    and implementing IT artifacts for DDD at one of the largest ship engine manufacturers
    in the world. Our main contribution is a set of design principles highlighting,
    besides decision quality, the importance of model comprehensibility, domain knowledge,
    and actionability of results.

  text: Augmented Reality (AR) based teaching and learning has evolved rapidly over
    the past years. Re-searchers have shown that AR has the potential to deliver persuasive
    learning experiences in for-mal teaching (e.g., in classrooms) and in informal
    learning environments (e.g., museums). Howev-er, comparatively little extant research
    is firmly grounded in learning theories and applies rigor-ous empirical methods
    to evaluate the effect of AR on learning performance. In order to build a cumulative
    body of knowledge on AR-based instructional design and its effectiveness, it is
    neces-sary to consolidate both the theoretical foundations of and empirical evidence
    for using AR for teaching and learning. Against this background we conducted a
    focused systematic literature re-view on theoretical and empirical foundations
    of AR in education. We identify theory-based de-sign elements and empirical measures
    for developing and applying AR teaching and learning ap-plications and consolidate
    them in a design framework.

  text: Emotions spread through online and offline social networks and subsequently
    influence individuals’ decisions and behaviours. Empirical studies on emotional
    contagion are almost non-existent in infor-mation systems research, leaving a
    gap in understanding how individuals are affected by emotions ex-pressed in online
    sources. Online newspaper articles and the associated readers’ comments provide
    a rich and mostly unfiltered data source that is utilized in this work to identify
    emotional contagion effects between newspaper publishers and its readers. By applying
    lexicon-based sentiment analysis and multi-level linear regression models to 1,151
    online newspaper articles and 28,948 associated readers' com-ments, we model the
    relationships between sentiments in newspaper articles and comments. The results
    provide empirical support for emotional contagion effects between emotions expressed
    in online news-paper articles and emotions expressed in readers' comments. Linguistic,
    psychological and methodo-logical limitations are considered and discussed.

  text: 'Recent growth in data volume, variety, and velocity led to an increased demand
    for high-performance data processing and analytics solutions. In-memory computing
    (IMC) enables organizations to boost their information processing capacity, and
    is widely acknowledged to be one of the leading strategic technologies in the
    field of enterprise systems. The majority of technology vendors now have IMC technologies
    in their portfolio, and the interest of companies in adopting such solutions in
    order to benefit from big data is increasing. Although there is first research
    on the business value of IMC in the form of case studies, there is a lack of large-scale
    quantitative evidence on the positive effect of such solutions on firm performance.
    Based on a unique panel data set of IMC adoption information and financial firm
    performance data for a sample of companies from the Fortune 500 list this study
    aims at explaining the relationship between the adoption of IMC solutions and
    firm performance. In this research-in-progress paper we discuss the theoretical
    background of our work, describe the proposed research design, and develop five
    hypotheses for later testing. Our work aims at contributing to the research streams
    on IT business value and business analytics by helping to better understand the
    nature of the interdependencies between IMC adoption and firm performance. '

  text: Organizational culture represents a key success factor in highly competitive
    environments, such as, the IT sector. Thus, IT companies need to understand what
    makes up a culture that fosters employee performance. While existing research
    typically uses self-report questionnaires to study the relation of culture and
    the success of companies, the validity of this approach is often discussed and
    researchers call for new ways of studying culture. Therefore, our research goal
    is to present an alternative ap-proach to culture analysis for examining which
    cultural factors matter to the IT workforce. Our study builds on 112,610 online
    reviews of Fortune 500 IT companies collected from Glassdoor, an online platform
    on which current and former employees can anonymously review companies and their
    man-agement. We perform an automated content analysis to identify cultural factors
    that employees em-phasize in their reviews. Through a regression analysis on numerical
    employee satisfaction ratings, we find that a culture of learning and performance
    orientation contributes to employee motivation, while a culture of assertiveness
    and gender inegalitarianism has a strong negative influence on em-ployees’ satisfaction
    in the IT workforce. Future research can apply our approach as an alternative
    method to quantifying culture and its impact on other variables.

  text: Analysts have estimated that more than 80 percent of today’s data is stored
    in unstructured form (e.g., text, audio, image, video)—much of it expressed in
    rich and ambiguous natural language. Traditionally, to analyze natural language,
    one has used qualitative data-analysis approaches, such as manual coding. Yet,
    the size of text data sets obtained from the Internet makes manual analysis virtually
    impossible. In this tutorial, we discuss the challenges encountered when applying
    automated text-mining techniques in information systems research. In particular,
    we showcase how to use probabilistic topic modeling via Latent Dirichlet allocation,
    an unsupervised text-mining technique, with a LASSO multinomial logistic regression
    to explain user satisfaction with an IT artifact by automatically analyzing more
    than 12,000 online customer reviews. For fellow information systems researchers,
    this tutorial provides guidance for conducting text-mining studies on their own
    and for evaluating the quality of others.

  text: Business operations are becoming more and more integrated with the real-time
    intelligence. Core business activities are being carried out through OLTP systems
    that provide limited monitoring capabilities of the running process instances.
    The article shows how to turn the gap between the classic transactional system
    and the process-centric approach into an organization that provides more accurate
    and faster decisions on the strategic and operational management levels. This
    study aims at determination of what kind of information can be retrieved during
    the process execution and it tries to identify the need for the real-time process
    intelligence on the example of the order-to-cash process. Furthermore, we compare
    two architectural approaches of the real-time process intelligence monitoring
    system. The proposed frameworks retrieve process data from the ERP system in order
    to record crucial performance indicators on a real-time basis with the use of
    the in-memory technology.

  text: Mobile application development is an emerging lucrative and fast growing market.
    With the steady growth of the number of apps in the repositories the providers
    will inevitably face the need to fine-grain the existing hierarchy of categories
    used to organize the apps. In this paper we present a method to bootstrap the
    categorization process via topic modeling. We apply Latent Dirichlet Allocation
    (LDA) to the textual descriptions of iTunes apps in order to identify recurrent
    topics in the collection. We evaluate and discuss the results obtained from training
    the model on a set of almost 600,000 English-language app descriptions. Our results
    demonstrate that automated categorization via LDA-based topic modeling is a promising
    approach, that can help to structure, analyze and manage the content of app repositories.
    The topics produced complement the original iTunes categories, concretize and
    extend them by providing insights into the underlying category content.
