ENTERPRISE ARCHITECTURE AS A MEANS FOR COORDINATION – AN EMPIRICAL STUDY ON ACTUAL AND POTENTIAL PRACTICE
Enterprise architecture management (EAM) is considered a means to guide the alignment of business- and IT-related concerns from an enterprise-wide perspective. Our goal in this paper is to understand by which means EAM supports this coordination task today and potentially in the future. We designed a questionnaire and conducted an empirical study (n=95) with participants from the field of EAM. Based on common coordination mechanisms from literature, we analyze (1) the relation between coordination mechanism and their current EAM support, (2) to what degree participants are aware of opportunities of EAM supporting coordination mechanisms, and (3) what the perceived gap between potential and realized EAM coordination support is. An exploratory factor analysis leads to three factors that represent coordination mechanisms in enterprises. Using these factors, we group participating enterprises in three different clusters: (1) non-coordinators, (2) dominators and (3) negotiators. We find that a similar awareness of opportunities exists in all three clusters, yet there are gaps in the realization of EAM coordination support: non-coordinators show the lowest realization, negotiators the highest. Based on this clustering, we provide implications on further EAM development options
Crossing the Line: Overcoming Knowledge Boundaries in Enterprise Transformation
Enterprise transformations are fundamental changes in an organization. Such changes typically affect different stakeholder groups (e.g., program managers, business managers) that exhibit a significant diversity regarding their members’ knowledge, goals, and underlying assumptions. Yet, creating shared understanding among diverse stakeholder groups in transformations is a main antecedent for success. The paper analyzes which properties of enterprise architecture models contribute to syntactic, semantic, and pragmatic capacities which helps to create shared understanding among stakeholder groups involved in enterprise transformation. The differences among stakeholder groups are assessed through the lens of knowledge boundaries, and enterprise architecture models are assessed through the lens of boundary objects. A research model is developed and empirically tested that describes which boundary object properties are required to overcome three progressively complex knowledge boundaries – syntactic, semantic, and pragmatic. The findings show which boundary object properties contribute to a respective capacity needed to overcome each of the three knowledge boundaries. Specifically, the results show that for (1) a syntactic capacity, concrete and modular enterprise architecture (EA) models are helpful; (2) a semantic capacity, visual EA model properties are relevant, and (3) a pragmatic capacity, broad stakeholder participation is conductive
Understanding Coordination Support of Enterprise Architecture Management – Empirical Analysis and Implications for Practice
Enterprise architecture management (EAM) is a means to guide the consistent evolution of business and IT artifacts from an enterprise-wide perspective. This paper aims at understanding the means by which EAM supports this coordination task. Informed by theory of coordination and based on empirical data (n=95) we group participating enterprises in different clusters: (1) non-coordinators, (2) dominators and (3) negotiators. We find that a similar awareness of opportunities exists in all three clusters, yet there are gaps in the realization of EAM coordination support: non-coordinators show the lowest realization, negotiators the highest. Based on this clustering and two follow-up focus groups, we provide implications about the occurrence of the clusters in enterprises and on further EAM development options

Charting Coordination Needs in Large-Scale Agile Organisations with Boundary Objects and Methodological Islands
Large-scale system development companies are increasingly adopting agile methods. While this adoption may improve lead-times, such companies need to balance two trade-offs: (i) the need to have a uniform, consistent development method on system level with the need for specialised methods for teams in different disciplines (e.g., hardware, software, mechanics, sales, support); (ii) the need for comprehensive documentation on system level with the need to have lightweight documentation enabling iterative and agile work. With specialised methods for teams, isolated teams work within larger ecosystems of plan-driven culture, i.e., teams become agile “islands”. At the boundaries, these teams share knowledge which needs to be managed well for a correct system to be developed. While it is useful to support diverse and specialised methods, it is important to understand which islands are repeatedly encountered, the reasons or factors triggering their existence, and how best to handle coordination between them. Based on a multiple case study, this work presents a catalogue of islands and the boundary objects between them. We believe this work will be beneficial to practitioners aiming to understand their ecosystems and researchers addressing communication and coordination challenges in large-scale development
Vegetation traits of pre-Alpine grasslands in southern Germany
The data set contains information on aboveground vegetation traits of > 100 georeferenced locations within ten temperate pre-Alpine grassland plots in southern Germany. The grasslands were sampled in April 2018 for the following traits: bulk canopy height; weight of fresh and dry biomass; dry weight percentage of the plant functional types (PFT) non-green vegetation, legumes, non-leguminous forbs, and graminoids; total green area index (GAI) and PFT-specific GAI; plant water content; plant carbon and nitrogen content (community values and PFT-specific values); as well as leaf mass per area (LMA) of PFT. In addition, a species specific inventory of the plots was conducted in June 2020 and provides plot-level information on grassland type and plant species composition. The data set was obtained within the framework of the SUSALPS project (“Sustainable use of alpine and pre-alpine grassland soils in a changing climate”; https://www.susalps.de/) to provide in-situ data for the calibration and validation of remote sensing based models to estimate grassland traits
The Interplay Between Strictness of Policies and Individuals’ Self-Regulatory Efforts: Associations with Handwashing During the COVID-19 Pandemic
Background
Patterns of protective health behaviors, such as handwashing and sanitizing during the COVID-19 pandemic, may be predicted by macro-level variables, such as regulations specified by public health policies. Health behavior patterns may also be predicted by micro-level variables, such as self-regulatory cognitions specified by health behavior models, including the Health Action Process Approach (HAPA).
Purpose
This study explored whether strictness of containment and health policies was related to handwashing adherence and whether such associations were mediated by HAPA-specified self-regulatory cognitions.
Methods
The study (NCT04367337) was conducted among 1,256 adults from Australia, Canada, China, France, Gambia, Germany, Israel, Italy, Malaysia, Poland, Portugal, Romania, Singapore, and Switzerland. Self-report data on cross-situational handwashing adherence were collected using an online survey at two time points, 4 weeks apart. Values of the index of strictness of containment and health policies, obtained from the Oxford COVID-19 Government Response Tracker database, were retrieved twice for each country (1 week prior to individual data collection).
Results
Across countries and time, levels of handwashing adherence and strictness of policies were high. Path analysis indicated that stricter containment and health policies were indirectly related to lower handwashing adherence via lower self-efficacy and self-monitoring. Less strict policies were indirectly related to higher handwashing adherence via higher self-efficacy and self-monitoring.
Conclusions
When policies are less strict, exposure to the SARS-CoV-2 virus might be higher, triggering more self-regulation and, consequently, more handwashing adherence. Very strict policies may need to be accompanied by enhanced information dissemination or psychosocial interventions to ensure appropriate levels of self-regulation
Recovery self-efficacy and intention as predictors of running or jogging behavior: a cross-lagged panel analysis over a two-year period
Objectives: The study investigates whether two kinds of self-efficacy and intention predict regular running or jogging behavior over 2 yr. Maintenance self-efficacy refers to beliefs about one's ability to maintain a behavior, whereas recovery self-efficacy pertains to beliefs about one's ability to resume a behavior after a setback.
Design and methods: Longitudinal data from runners (N=139, 80% men) were collected twice with a time gap of 2 yr. Results: Cross-lagged panel analysis revealed that recovery self-efficacy and intention jointly predicted running/jogging behavior 2 yr later, whereas running/jogging behavior did not predict recovery self-efficacy and intention. No effects of maintenance self-efficacy were found. The majority of participants (n=120) experienced at least one 2-week period of decline in running or jogging behavior. Among those who experienced lapses, recovery self-efficacy remained the only significant social-cognitive predictor of behavior.
Conclusions: Recovery self-efficacy is a crucial predictor of regular running or jogging behavior over 2 yr
Winding number and non-BPS bound states of walls in nonlinear sigma models
Non-supersymmetric multi-wall configurations are generically unstable. It is
proposed that the stabilization in compact space can be achieved by introducing
a winding number into the model. A BPS-like bound is studied for the energy of
configuration with nonvanishing winding number. Winding number is implemented
in an supersymmetric nonlinear sigma model with two chiral scalar
fields and a bound states of BPS and anti-BPS walls is found to exist in
noncompact spaces. Even in compactified space , this nontrivial bound
state persists above a critical radius of the compact dimension.Comment: 20pages, 14 figures, minor misprint corrections, figures added,
