Report from GI-Dagstuhl Seminar 16394: Software Performance Engineering in the DevOps World
This report documents the program and the outcomes of GI-Dagstuhl Seminar
16394 "Software Performance Engineering in the DevOps World".
The seminar addressed the problem of performance-aware DevOps. Both, DevOps
and performance engineering have been growing trends over the past one to two
years, in no small part due to the rise in importance of identifying
performance anomalies in the operations (Ops) of cloud and big data systems and
feeding these back to the development (Dev). However, so far, the research
community has treated software engineering, performance engineering, and cloud
computing mostly as individual research areas. We aimed to identify
cross-community collaboration, and to set the path for long-lasting
collaborations towards performance-aware DevOps.
The main goal of the seminar was to bring together young researchers (PhD
students in a later stage of their PhD, as well as PostDocs or Junior
Professors) in the areas of (i) software engineering, (ii) performance
engineering, and (iii) cloud computing and big data to present their current
research projects, to exchange experience and expertise, to discuss research
challenges, and to develop ideas for future collaborations
Grand Challenges of Traceability: The Next Ten Years
In 2007, the software and systems traceability community met at the first
Natural Bridge symposium on the Grand Challenges of Traceability to establish
and address research goals for achieving effective, trustworthy, and ubiquitous
traceability. Ten years later, in 2017, the community came together to evaluate
a decade of progress towards achieving these goals. These proceedings document
some of that progress. They include a series of short position papers,
representing current work in the community organized across four process axes
of traceability practice. The sessions covered topics from Trace Strategizing,
Trace Link Creation and Evolution, Trace Link Usage, real-world applications of
Traceability, and Traceability Datasets and benchmarks. Two breakout groups
focused on the importance of creating and sharing traceability datasets within
the research community, and discussed challenges related to the adoption of
tracing techniques in industrial practice. Members of the research community
are engaged in many active, ongoing, and impactful research projects. Our hope
is that ten years from now we will be able to look back at a productive decade
of research and claim that we have achieved the overarching Grand Challenge of
Traceability, which seeks for traceability to be always present, built into the
engineering process, and for it to have "effectively disappeared without a
trace". We hope that others will see the potential that traceability has for
empowering software and systems engineers to develop higher-quality products at
increasing levels of complexity and scale, and that they will join the active
community of Software and Systems traceability researchers as we move forward
into the next decade of research

Civilizational structure of regional integration organizations
The paper advances a new comprehensive complex approach to the investigation of the civilizational aspects in the development of regional associations of countries.
The research starts with the overview of historical dimensions of the civilizational approach and the contribution of the founding scholars to its development. It continues with the analysis of the scientific and methodological input of the followers and the critics of this approach.
The authors suggest their theoretical approach to the identification of the modern local civilizations according to six parameters: natural, biological, technical, economic, social, and governing.
The civilizational affiliation of countries and the civilizational structure of major 17 regional associations of countries are identified.
The results demonstrate that some regional groups have been more homogeneous in terms of civilizational composition, others – less homogeneous, which does not interfere with their dynamic development. However, the logic of the historical dynamics of human development indicates the inevitability of changing the current situation through prolonged civilizational conflicts resulting in significant changes in the global social dynamics and the civilizational structure of the world and of regional associations of countries.
The identification of the civilization structure of countries and regional associations contributes to the rational decision-making in the areas of international economic relations and to the formation of the integration/disintegration policies on the national and regional levels.
It is predicted that from 2030 global social dynamics will undergo a fundamental breakthrough that will radically change the civilizational structure of the world and regional unions of countries.
Methods. The research is based on the application of the systemic and historical approach, combined with the methods of analysis, synthesis, analogy, abstraction, generalization and method of individual expert assessment.
Novelty of the research. The authors have identified the civilizational structure of countries using statistically available criteria for the six groups of factors, which allows to determine the homogeneity level of the major regional groups of countries.
Practical significance. Identification of civilization structure of countries and regional
associations creates the opportunity for adjusting national and subregional integration and disintegration policies.
The aim of the study is to determine the civilizational structure of the regional associations of countries. To achieve this goal the following tasks are set and solved:
–to analyze and optimize the existing approaches to the identification of local civilizations;
–to identify the current state of the countries’ belonging to this or that civilization, their civilizational structure;
–to reveal the civilizational structure of the major regional blocs
Network geography: relations, interactions, scaling and spatial processes in GIS
This chapter argues that the representational basis of GIS largely avoidseven the most rudimentary distortions of Euclidean space as reflected, forexample, in the notion of the network. Processes acting on networks whichinvolve both short and longer term dynamics are often absent from GIscience. However a sea change is taking place in the way we view thegeography of natural and man-made systems. This is emphasising theirdynamics and the way they evolve from the bottom up, with networks anessential constituent of this decentralized paradigm. Here we will sketchthese developments, showing how ideas about graphs in terms of the waythey evolve as connected, self-organised structures reflected in theirscaling, are generating new and important views of geographical space.We argue that GI science must respond to such developments and needs tofind new forms of representation which enable both theory andapplications through software to be extended to embrace this new scienceof networks
Evolution in Economic Geography: Institutions, Regional Adaptation and Political Economy
Economic geography has, over the last decade or so, drawn upon ideas from
evolutionary economics in trying to understand processes of regional growth and
change, with the concept of path dependence assuming particular prominence.
Recently, some prominent researchers have sought to delimit and develop an
evolutionary economic geography (EEG) as a distinct approach, aiming to create a
more coherent and systematic theoretical framework for research. This paper
contributes to debates on the nature and development of EEG. It has two main aims.
First, we seek to restore a broader conception of social institutions and agency to
EEG, informed by the recent writings of institutional economists like Geoffrey
Hodgson. Second, we link evolutionary concepts to political economy approaches,
arguing that the evolution of the economic landscape must be related to the broader
dynamics of capital accumulation, centred upon the creation, realisation and
geographical transfer of value. As such, we favour the utilisation of evolutionary and
institutional concepts within a geographical political economy approach rather than
the construction of a separate and theoretically ‘pure’ EEG; evolution in economic
geography, not an evolutionary economic geography
