Perceptions and Use of Anonymous Communication across Cultures

We use social networks to communicate, keep in touch and express our opinions in a manner that has become completely ubiquitous. However, this very ubiquity and ease of expression have exposed another, contentious side – one where nobody can remain completely anonymous for long and where every conversation is stored in perpetuity. Some fear that the ephemeral quality of a social interaction has been lost, which threatens our right to be forgotten and freedom of expression. In this paper, we look at why people engage in anonymous communication, and if there is a perceived need for legal protection of anonymous communication. Moreover, this paper attempts to identify cultural stratifications, if any, in the ways in which people of various cultures perceive the importance of anonymous communications. The primary cultural clusters we studied are Anglo (e.g. Australia, Canada, England, USA) and Eastern European (e.g. Albania, Bulgaria, Moldova, Russia). Our data set consists of 374 responses to our survey from people belonging to these cultures. We found that perceived freedom afforded by anonymous communication and propensity to trust are both positively related to use of anonymous communication, which in turn is positively related to perceived need for legal protection of anonymous communication. Moreover, we found that the relationship between propensity to trust and use of anonymous communication is stronger for respondents in the Eastern Europe cultural cluster than for respondents in non-Eastern Europe cultural clusters

Agile in Teaching and Learning: Conceptual Framework and Research Agenda

Agile software development methods are widespread in industry, and there is a wealth of academic research and practitioner publications currently available from this perspective. With the rise of Agile within companies worldwide, it is increasingly important for information systems education to keep up with this trend to ensure curriculum and courses are up-to-date. Students in the computing disciplines must be prepared to enter a job market where Agile is commonplace. As such, the topic of Agile in teaching and learning is critically important. The current special issue includes a rich collection of articles providing information systems educators with research-based, practical approaches for both teaching Agile (“the what”) and using Agile as a pedagogical approach (“the how”). In an effort to assist information systems educators categorize the growing amount of literature related to Agile in teaching and learning, a conceptual framework is provided which places the literature along the two axes of pedagogy (“the how”) and the content (“the what”) ranging from other, non-Agile to Agile. Finally, the authors present a call for future research integrating Agile on a meta-level in the course development process. We hope that this special issue inspires educators and researchers to consider integrating Agile into their teaching and learning

Automated Negotiations Under Uncertain Preferences

Automated Negotiation is an emerging field of electronic markets and multi-agent system research. Market engineers are faced in this connection with computational as well as economic issues, such as individual rationality and incentive compatibility. Most literature is focused on autonomous agents and negotiation protocols regarding these issues. However, common protocols show two deficiencies: (1) neglected consideration of agents’ incentives to strive for social welfare, (2) underemphasised acknowledgement that agents build their decision upon preference information delivered by human principals. Since human beings make use of heuristics for preference elicitation, their preferences are subject to informational uncertainty. The contribution of this paper is the proposition of a research agenda that aims at overcoming these research deficiencies. Our research agenda draws theoretically and methodologically on auctions, iterative bargaining, and fuzzy set theory. We complement our agenda with simulation-based preliminary results regarding differences in the application of auctions and iterative bargaining

Agile Teaching and Learning in Information Systems Education: An Analysis and Categorization of Literature

In this paper, we analyze and categorize research related to Agile teaching and learning in Information Systems education using an existing conceptual framework. To this end, a systematic literature review beginning with 642 papers led to the identification of 30 relevant papers written in English and published through 2018 in academic IS outlets. Our analysis reveals three ways in which Information Systems educators incorporate Agile into their courses: 1) using Agile as a pedagogical approach to teach non-Agile content, 2) using Agile as a pedagogical approach to teach Agile content, and 3) using non-Agile pedagogical approaches to teach Agile content. The majority of relevant papers were published between 2016 and 2018. We present an analysis of the three instructional approaches to serve as a resource for interested individuals and recommend directions for future studies related to Agile teaching and learning in IS education

The unique and common effects of emotional intelligence dimensions on job satisfaction and facets of job performance:an exploratory study in three countries

Previous empirical studies have either used a unidimensional or a multidimensional analytical approach to examine the consequences of emotional intelligence (EI). In this exploratory study we integrate and extend these two approaches, using a novel perspective to better understand the structure of the EI-job satisfaction and the EI-job performance relationship. Using commonality analysis and data from Germany, India, as well as the U.S. we partition the explained variance for job satisfaction, in- role performance, and extra-role performance into the variance that is uniquely explained by the individual EI dimensions and the variance that is common to sets of EI dimensions. We provide evidence that the EI dimensions are differently related to job satisfaction and job performance facets. Furthermore, the findings offer insights on how unique and common effects vary across countries. Partitioning the unique and commonly shared variance allows us to assess the true predictive power of individual EI dimensions and of sets of EI dimensions. Based on these findings, we discuss implications for theory development and provide future research directions

Degeneracy of vector-channel spatial correlators in high temperature QCD

We study spatial isovector meson correlators in $N_f=2$ QCD with dynamical domain-wall fermions on $32^3\times 8$ lattices at temperatures up to 380 MeV with various quark masses. We measure the correlators of spin-one isovector operators including vector, axial-vector, tensor and axial-tensor. At temperatures above $T_c$ we observe an approximate degeneracy of the correlators in these channels, which is unexpected because some of them are not related under $SU(2)_L \times SU(2)_R$ nor $U(1)_A$ symmetries. The observed approximate degeneracy suggests emergent $SU(2)_{CS}$ (chiral-spin) and $SU(4)$ symmetries at high $T$.Comment: 8 pages, 2 tables, 4 figures.

Neck linker docking is critical for Kinesin-1 force generation in cells but at a cost to motor speed and processivity.

Kinesin force generation involves ATP-induced docking of the neck linker (NL) along the motor core. However, the roles of the proposed steps of NL docking, cover-neck bundle (CNB) and asparagine latch (N-latch) formation, during force generation are unclear. Furthermore, the necessity of NL docking for transport of membrane-bound cargo in cells has not been tested. We generated kinesin-1 motors impaired in CNB and/or N-latch formation based on molecular dynamics simulations. The mutant motors displayed reduced force output and inability to stall in optical trap assays but exhibited increased speeds, run lengths, and landing rates under unloaded conditions. NL docking thus enhances force production but at a cost to speed and processivity. In cells, teams of mutant motors were hindered in their ability to drive transport of Golgi elements (high-load cargo) but not peroxisomes (low-load cargo). These results demonstrate that the NL serves as a mechanical element for kinesin-1 transport under physiological conditions

Reallabore im Kontext transformativer Forschung : Ansatzpunkte zur Konzeption und Einbettung in den internationalen Forschungsstand

Reallabore sind derzeit ein populärer Forschungsansatz an der Schnittstelle zwischen Wissenschaft und Gesellschaft. Neben vermuteten Potentialen, wie der Erzeugung von Transformationswissen und einem Beitrag zu gesellschaftlichem Wandel, gibt es auch vielfältige offene Fragen, u. a. im Hinblick auf das Verhältnis zu transdisziplinärer Forschung, der Übertragbarkeit des erzeugten Wissens oder der Gestaltung von Experimenten in der "realen Welt". Auch eine breit getragene Definition von Reallaboren existiert derzeit nicht. Dieses Diskussionspapier möchte daher dreierlei leisten: Es beginnt mit dem Herausarbeiten von Reallabor-Merkmalen als a) Beitrag zu Transformationsprozessen, b) Experimenten als zentraler Forschungsmethode, c) Transdisziplinarität als Forschungsmodus, d) dem Ziel der Ausweitung und Übertragung der Ergebnisse und e) Reallaboren als Orten wissenschaftlichen und gesellschaftlichen Lernens. Im Nachgang werden diese Merkmale durch Rückbezug auf die einschlägige Literatur vertieft diskutiert. Abschließend werden mit Reallaboren vergleichbare Forschungsansätze (Sustainable Living Labs, Urban Transition Labs und Niche Experiments) im Hinblick auf ihre Ausgestaltung der fünf herausgearbeiteten Merkmale vorgestellt und Reallabore damit in den internationalen Forschungskontext eingebettet. Das Diskussionspapier will damit Forschenden und Praktiker_innen in Reallaboren eine Orientierung ermöglichen. Die vorgestellten konzeptionellen Überlegungen basieren auf einem thematischen Literatur-Review, ebenso wie Diskussionen mit Reallabor- und Transformationsforschenden in nationalen und internationalen Kontexten. Sie sind im Rahmen der Begleitforschung des Forschungsprojektes "ForReal" zu den Baden-Württembergischen Reallaboren entstanden. Dem Charakter eines Diskussionspapieres entsprechend sind die hier vorstellten Rahmungen zum Reallaboransatz als Angebot zur Diskussion, Erweiterung und Verbesserung zu verstehen

Shaping Real-World Laboratories by Comparing Them

Various experimental approaches of transformative research in real-world settings have emerged. Yet, similarities, differences, and specific contributions remain unclear. A characteristic-based comparison reveals complementarities and provides orientation. Real-world laboratories (RwLs, German Reallabore) belong to a family of increasingly popular experimental and transdisciplinary research approaches at the science-society interface. As these approaches in general, and RwLs in particular, often lack clear definitions of key characteristics and their operationalization, we make two contributions in this article. First, we identify five core characteristics of RwLs: contribution to transformation, experimental methods, transdisciplinary research mode, scalability and transferability of results, as well as scientific and societal learning and reflexivity. Second, we compare RwLs to similar research approaches according to the five characteristics. In this way, we provide an orientation on experimental and transdisciplinary research for societal transformations, and reveal the contributions of this type of research in supporting societal change. Our findings enable learning across the different approaches and highlight their complementarities, with a particular focus on RwLs

Personality and games : enhancing online surveys through gamification

In this research, we evaluate the moderating role of personality on enjoyment and attention associated with a gamified data collection instrument, and the attractiveness of a surveying organization. In an online experiment, we compare a gamified survey with a traditional survey. The results suggest that gamified surveys are more enjoyable and users are more attentive when filling out gamified surveys. Specific personality traits moderate the effect of attention and enjoyment related to gamification, and the enjoyment associated with gamification increases the attractiveness of a surveying organization. These findings have theoretical and practical implications to improve the design of existing online surveys
