Exploring Maintainability Assurance Research for Service- and Microservice-Based Systems: Directions and Differences
To ensure sustainable software maintenance and evolution, a diverse set of activities and concepts like metrics, change impact analysis, or antipattern detection can be used. Special maintainability assurance techniques have been proposed for service- and microservice-based systems, but it is difficult to get a comprehensive overview of this publication landscape. We therefore conducted a systematic literature review (SLR) to collect and categorize maintainability assurance approaches for service-oriented architecture (SOA) and microservices. Our search strategy led to the selection of 223 primary studies from 2007 to 2018 which we categorized with a threefold taxonomy: a) architectural (SOA, microservices, both), b) methodical (method or contribution of the study), and c) thematic (maintainability assurance subfield). We discuss the distribution among these categories and present different research directions as well as exemplary studies per thematic category. The primary finding of our SLR is that, while very few approaches have been suggested for microservices so far (24 of 223, ?11%), we identified several thematic categories where existing SOA techniques could be adapted for the maintainability assurance of microservices
Ontology-based patterns for the integration of business processes and enterprise application architectures
Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge
the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture
descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of
software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data.
Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an
ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their
applicability in business process-driven application integration is demonstrated
The geography of entrepreneurship in the New York metropolitan area
This article was presented at a conference organized by the Federal Reserve Bank of New York in April 2005, "Urban Dynamics in New York City." The goal of the conference was threefold: to examine the historical transformations of the engine-of-growth industries in New York and distill the main determinants of the city's historical dominance as well as the challenges to its continued success; to study the nature and evolution of immigration flows into New York; and to analyze recent trends in a range of socioeconomic outcomes, both for the general population and recent immigrants more specifically.Business enterprises - New York (N.Y.) ; Economic conditions - New York (N.Y.) ; Federal Reserve District, 2nd ; Urban economics
Do we need one science of production in healthcare?
The question addressed is: Is there need, in health care, for one consolidated science of production? For responding to this question, the classical science of production is reviewed and the current approaches to production and service in healthcare are analysed as for their evolution and current status. It is found that these current movements are not self-aware of the restrictions deriving from their backgrounds, and of the resultant partiality in their approaches. It is concluded that improvement of healthcare is slowed down by the fragmentation of the related disciplines; thus one consolidated science of production (of healthcare) is needed
A Tissue Engineering product development pathway
Tissue engineering is a field of inquiry and research that uses engineering techniques and principles of biological sciences to develop functional substitutes for reconstruction of damaged organs. Commercial translation of tissue engineering products is currently in progress all over the world. Many companies are moving their interest towards this market segment that grows by 6% per year. Aim of this thesis is to probe the possibility of developing tissue engineering products in the most cost-effective way, minimizing the industrial risk and developing a specific fund raising model. Tissue engineering is based on three main features: cells, scaffolds and bioreactors. Cells are seeded on a scaffold and cultured in a bioreactor in order to obtain a tissue engineering product. Nevertheless, developing cell carrying products is hampered by certification claims ("advanced therapies" certification rules) that unbearably increase R&D and certification costs and can be faced by either big companies or start-ups of big companies and spin-offs of complex aggregates of research centers involved in advanced cell research. On the other hand, scaffolds (certification class IIb) and bioreactors for tissue engineering (certification class I) can be developed with a lower economic effort, being the competition based on innovation, since their market is in the "growth phase" for scaffolds and in the "introduction phase" for bioreactors in the Levitt's product life cycle theory. Purpose of this thesis is to basically study scaffold and bioreactor features, then to preliminarily design some models of bioreactors and, eventually, to set a business model, based on private and public fund raising, aimed to the development of scaffolds for dental implantology and of bioreactors for cardiovascular and bone tissue engineering. Finally, a business plan of a company being spin-off of Politecnico di Torino and industrial start-up has been elaborate

Improving customer satisfaction: changes as a result of Customer Value Discovery
Objective: To identify Gold Standard Services for customers in an academic library and determine whether interventions following the identification of customer value increased student satisfaction. Methods: “Customer Discovery Workshops” were undertaken with academic staff and undergraduate on‐campus students to provide managers and library staff with information on the services and resources that customers valued, and what irritated them about existing services and resources. The impact of interventions was assessed two years after the research using a university student satisfaction survey and an independent national student satisfaction survey. Results: The findings resulted in significant changes to the way forward‐facing customer services were delivered. A number of value adding services were introduced for the customer. Overall customer satisfaction was improved. Evidence Based Library and Information Practice 2008, 3:1 34 Conclusions: The Customer Value Discovery research has created a culture of innovation and continuous improvement. An operational plan was introduced to track activity and performance against the objectives identified in the customer value research. However, there is a constant need to innovate
Anti-money laundering and counter-terrorism financing survey of regulated businesses in Australia - methodology report
This report provides a stand-alone description of how the Australian Institute of Criminology’s Anti-money Laundering/Counter-terrorism Financing Survey of regulated businesses was undertaken, emphasising the importance of understanding the methodology and design of this national census of regulated businesses in Australia.
As is often the case with social scientific research of a quantitative nature, the detail of how surveys were conducted are sometimes relegated to deep within a long report, or attached in a lengthy appendix, often being overlooked by the average reader.
This report provides a stand-alone description of how the Australian Institute of Criminology’s Anti-money Laundering/Counter-terrorism Financing Survey of regulated businesses was undertaken, thus emphasising the importance of understanding the methodology and design of this national census of regulated businesses in Australia.
It reviews all of the procedures and steps undertaken from a data collection and methodological perspective and provides an important accompaniment to the major survey report published in conjunction with this methodological review.
Both reports should be read together. The current report provides a summary of the methodological approach, consolidation of assorted reports generated throughout the study, a review of sample utilisation and response dynamics and a summary of issues for consideration for future similar surveys
Overhauling corporate taxation in the digital economy. CEPS Policy Insights No 2019-15/October 2019
Is the corporate income tax (CIT) still an efficient system for taxing companies today? The CIT was
introduced when economies were characterised primarily by tangible assets and goods and by limited
international trade. Globalisation, digitalisation and the increasing weight of immaterial goods in
company transactions and balance sheets have rendered that system outdated. These radical changes
call for equally radical reflections on how to reform the CIT, bearing in mind the need for a corporate
tax system that is fit for both the digital and the traditional economy, in developing and developed
countries alike.
Rather than offering a complete solution, this paper discusses various approaches that could contribute
to a solution. First, we suggest that the CIT base should always be strictly aligned with the accounting
profit and loss account, eschewing special adjustments for tax purposes. Second, a more radical
possibility would be to abandon altogether the reference to corporate income and tax companies
instead on cash flow, based on destination. And, third, the possibility could also be explored to tax
companies with reference to ‘presumptive’ indicators of activity, rather than on the basis of public
accounts. Presumptive indicators are already used in federal systems to allocate corporate income
among decentralised jurisdictions. These propositions would not be viable without international
agreement, at least at the level of the European Union. Such an agreement may prove difficult given
the conflicts of interest between EU member states and between them and the United State
