Investigation of the Tribal Park Concept and Opportunities for the Blackfeet Nation

The Tribal Park model is an emerging tool being used by indigenous groups in the United States and Canada for the management of unique and sacred natural areas, in some cases setting aside existing indigenous owned land, and in others regaining control of land management decisions in traditional territory. Currently in North America there are several sites that have self-identified as Tribal Parks. There is a lack of research regarding Tribal Park development in North America, which creates challenges for indigenous groups interested in pursuing a conservation designation of this type. Using an analysis of five Tribal Park case studies this thesis identifies the key components of these Tribal Parks. Specifically focusing on the economic, cultural, and ecological aspects of each case study. This research then uses interviews with members of the Blackfeet Nation, to explore the potential interest in a Tribal Park on Blackfeet Nation lands. This study finds that though the Tribal Park concept varies across case studies based on the needs of the specific community, there are some important common aspects across cases. These aspects include: a bottom-up community driven planning process with programs in place to increase capacity of community members, exercising sovereignty over land-use decisions in traditional territory, and connectivity of landscapes and habitat protection. Some of the themes identified by Blackfeet Nation respondents were potential benefits from capturing visitor overflow from neighboring Glacier National Park, increased access to land by community members, and concerns regarding land-use conflicts between different user groups

Towards Model-Driven Development of Access Control Policies for Web Applications

We introduce a UML-based notation for graphically modeling systems’ security aspects in a simple and intuitive way and a model-driven process that transforms graphical specifications of access control policies in XACML. These XACML policies are then translated in FACPL, a policy language with a formal semantics, and the resulting policies are evaluated by means of a Java-based software tool

Challenges for the Adoption of Model-Driven Web Engineering Approaches in Industry

Model-driven web engineering approaches have become an attractive research and technology solution for Web application development. However, after 20 years of development, they have attracted little attention from the Industry due to the mismatch between technical versus research requirements. In this joint work between academia and industry, the authors present the current problems of using these approaches in scale and provide guidelines to convert them into viable industry solutions.Ministerio de ciencia e Innovación TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED

Quality-aware model-driven service engineering

Service engineering and service-oriented architecture as an integration and platform technology is a recent approach to software systems integration. Quality aspects ranging from interoperability to maintainability to performance are of central importance for the integration of heterogeneous, distributed service-based systems. Architecture models can substantially influence quality attributes of the implemented software systems. Besides the benefits of explicit architectures on maintainability and reuse, architectural constraints such as styles, reference architectures and architectural patterns can influence observable software properties such as performance. Empirical performance evaluation is a process of measuring and evaluating the performance of implemented software. We present an approach for addressing the quality of services and service-based systems at the model-level in the context of model-driven service engineering. The focus on architecture-level models is a consequence of the black-box character of services

ICD Management (ICDM) tool for embedded systems on aircrafts

International audienceIn the scope of on-board systems development and integration for aircrafts, ICDs (Interface Control Document/Description) are fundamental sources of information at same level that the functional requirements. ICD description must include feasible (bus capacity not exceeded, processing load under specific limits) and accurate (data precision, data retransmission rate, data consistency) inter-connectivity mechanisms, to support the application requirements needs, as well as the information must be easy to update and to maintain.On the other hand, DOORS (IBM) is a tool specialized on requirements management. It faces with aspects as traceability, version control, security (access control), changes control, data persistency and accessibility. DOORS is widely used and it is recognized as a reference tool in the scope of aeronautic developments.Nevertheless, ICD information usually is not managed with DOORS. The reason can be found in the specificities of the nature of ICD information, which suggests other approaches more suitable than DOORS.The alternative approaches are very diverse but most of them focus on handling information typified according to specific meta-models for ICD: databases, customized spreadsheets, and tabular descriptions. But whatever is the solution, it must address also, by its own means, the features of ICD derived of its “requirement nature”.This paper presents a solution based on the integration of DOORS with a user front-end developed with Model Driven Architecture (MDA) and Open Source technologies. It is intended to provide means to manage ICD data in a robust way (guaranteeing the correctness -syntactic, completeness, non ambiguity- of data, changes, versions, dependencies, ...) and additionally, to provide mechanisms to focus the effort on the data transformation rather than on the manual elaboration of derived artefacts

SensorCloud: Towards the Interdisciplinary Development of a Trustworthy Platform for Globally Interconnected Sensors and Actuators

Although Cloud Computing promises to lower IT costs and increase users' productivity in everyday life, the unattractive aspect of this new technology is that the user no longer owns all the devices which process personal data. To lower scepticism, the project SensorCloud investigates techniques to understand and compensate these adoption barriers in a scenario consisting of cloud applications that utilize sensors and actuators placed in private places. This work provides an interdisciplinary overview of the social and technical core research challenges for the trustworthy integration of sensor and actuator devices with the Cloud Computing paradigm. Most importantly, these challenges include i) ease of development, ii) security and privacy, and iii) social dimensions of a cloud-based system which integrates into private life. When these challenges are tackled in the development of future cloud systems, the attractiveness of new use cases in a sensor-enabled world will considerably be increased for users who currently do not trust the Cloud.Comment: 14 pages, 3 figures, published as technical report of the Department of Computer Science of RWTH Aachen Universit

Re-thinking technology and its growing role in enabling patient empowerment

© The Author(s) 2018. The presence and increase of challenges to eHealth in today’s society have begun to generate doubts about the capability of technology in patient empowerment, especially within the frameworks supporting empowerment. Through the review of existing frameworks and articulation of patient demands, weaknesses in the current application of technology to support empowerment are explored, and key constituents of a technology-driven framework for patient empowerment are determined. This article argues that existing usage of technology in the design, development and implementation of patient empowerment in the healthcare system, although well intentioned, is insufficiently constituted, primarily as a result of fragmentation. Systems theory concepts such as holism and iteration are considered vital in improving the role of technology in enabling patient empowerment

The role of the service concept in model-driven applications development

This paper identifies two paradigms that have influenced the design of distributed applications: the middleware-centred and the protocol-centred paradigm, and proposes a combined use of these two paradigms. This combined use incorporates major benefits from both paradigms: the ability to reuse middleware infrastructures and the ability to treat distributed coordination aspects as a separate object of design through the use of the service concept. A careful consideration of the service concept, and its recursive application, allows us to define an appropriate and precise notion of platform-independence that suits the needs of model-driven middleware application development

Using Ontologies for the Design of Data Warehouses

Obtaining an implementation of a data warehouse is a complex task that forces designers to acquire wide knowledge of the domain, thus requiring a high level of expertise and becoming it a prone-to-fail task. Based on our experience, we have detected a set of situations we have faced up with in real-world projects in which we believe that the use of ontologies will improve several aspects of the design of data warehouses. The aim of this article is to describe several shortcomings of current data warehouse design approaches and discuss the benefit of using ontologies to overcome them. This work is a starting point for discussing the convenience of using ontologies in data warehouse design.Comment: 15 pages, 2 figure
