An algorithm for comparative analysis of power and storage systems for maritime applications

This paper presents an innovative algorithm to compare traditional and innovative energy systems onboard for maritime applications. The solutions are compared adopting a multi-criteria method, considering four parameters (weight, volume, cost, emissions) and their relevance according to the kind of ship and navigation route. The algorithm, which includes a large and updated database of market solutions, leads to the implementation of HELM (Helper for Energy Layouts in Maritime applications) tool. HELM was conceived to support the design of maritime systems: it chooses the best technology comparing traditional marine diesel engines, propulsion systems with alternative fuels (methanol, ammonia, LNG) and innovative low-emission technologies (fuel cell and batteries). Two case studies are investigated: (i) a small passenger ship for short routes (ii) and a large size ro-ro cargo ship. For case (i), fuel cells represent a competitive solution, in particular considering navigation in emission control areas. For case study (ii) Internal Combustion Engines shows are the best solution. The evaluation of alternative fuels is performed, considering a sensitivity analysis on emissions’ importance: methanol, LNG, and ammonia are promising solutions. For case (i), the installation of electrical batteries is also evaluated to analyse potential advantages to reduce the amount of H2 stored onboard.

Competence Frameworks of Sustainable Entrepreneurship: A Systematic Review

The importance of the transformation to a sustainable economy for the protection from global crises such as climate change is widely recognized. Sustainable entrepreneurs are considered to play a key role in this transformation process as they create innovative market solutions with ecological, social, and economic value. So far, there is no consensus on competences students need to solve sustainability challenges as sustainable entrepreneurs. The aim of this article is to identify competence frameworks that enable competence-oriented education of future sustainable entrepreneurs. An academic search engine and a bibliographic database were screened for documents written in English and published between January 2010 and November 2020 to identify the existing competence frameworks discussed in the current literature in the field of Sustainable Entrepreneurial Education (SEE). The review process led to a set of 65 empirical and nonempirical works on SEE. A computer-assisted qualitative data analysis was used for this review. The data analysis showed an increasing number of SEE articles published over the last decade mostly in scientific journals (69.2%). Fifty-six (86.2%) of publications related to tertiary education. The data analysis revealed three stand-alone competence frameworks for Sustainable Entrepreneurship (SE). The frameworks show an overlap in content but differences in terms of construction, validation, complexity. All competence frameworks were developed for use in higher education institutions, which necessitates adaptation for use in other educational institutions. The analysis of 28 SEE interventions identified in the literature provides information on the reception of the frameworks for competence-based teaching and assessment.

Solar Photovoltaics in Pacific Island Nations: An Analysis of Rural Household Electrification Strategies in the RMI and Vanuatu

<p>Rural electrification of Pacific Island Countries (PICs) through renewable energy is necessary for poverty alleviation, energy security, improved health, and to mitigate the effects of climate change, with solar PV being the preferred technological solution. However, electrification projects in PICs have had a high rate of failure, which has led to the adoption of various electrification strategies. This research has analysed the essential criteria for creating effective and enduring electrification models for rural household-scale electrification in PICs. A case study on self-initiated solar PV home systems (SHSs) demonstrated rural end-users‘ ability and desire to maintain SHSs of their own accord, while at the same time liberating their community of reliance on kerosene. The results suggested that market solutions that pay sufficient attention to social dimensions of project design and implementation are more likely to be successful in meeting end-users needs and providing enduring results. Such approaches have fewer organizational layers, allow for end-user participation and education, and encourage self-initiative. The need for such social solutions is well documented in the development literature, yet many of the electrification programs in PICs did not allocate sufficient funds to understanding and incorporating these social aspects. This research concludes that a proper balance in the overarching program design between the technical and social focus of projects is required, as each are equally important for project effectiveness and durability.</p>

Four Internets

The book describes the Internet, and how Internet governance prevents it fragmenting into a ‘Splinternet’. Four opposing ideologies about how data flows around the network have become prominent because they are (a) implemented by technical standards, and (b) backed by influential geopolitical entities. Each of these specifies an ‘Internet’, described in relation to its implementation by a specific geopolitical entity. The four Internets of the title are: the Silicon Valley Open Internet, developed by pioneers of the Internet in the 1960s, based on principles of openness and efficient dataflow; the Brussels Bourgeois Internet, exemplified by the European Union, with a focus on human rights and legal administration; the DC Commercial Internet, exemplified by the Washington establishment and its focus on property rights and market solutions; and the Beijing Paternal Internet, exemplified by the Chinese government’s control of Internet content. These Internets have to coexist if the Internet as a whole is to remain connected. The book also considers the weaponization of the hacking ethic as the Moscow Spoiler model, exemplified by Russia’s campaigns of misinformation at scale; this is not a vision of the Internet, but is parasitic on the others. Each of these ideologies is illustrated by a specific policy question. Potential future directions of Internet development are considered, including the policy directions that India might take, and the development of technologies such as artificial intelligence, smart cities, the Internet of Things, and social machines. A conclusion speculates on potential future Internets that may emerge alongside those described.

The Third Internet: The DC Commercial Internet

This chapter describes the DC Commercial Internet. The ideal consists of economic liberty, market solutions to resource allocation problems, property rights over the Internet, and exploitation of positive externalities. The exemplar is the United States, especially its Supreme Court, which has judged networks as private spaces (‘walled gardens’) which can and should be monetized as their owners prefer. Such an approach, it is argued, will lead to greater innovation and value creation for the public, even at the cost of interoperability and net neutrality. Social networks have gained from this view, able to create closed networks within walled gardens benefiting from network effects to collect data about members. Facebook has offered free services in the developing world in order to bring more people online within its boundaries. An attempt to sell the .org domain to a private equity company, however, foundered. This model has been called ‘surveillance capitalism’.

Toward the commoning of governance

Conventional political thought and practice continue to be stifled by a dilemma of choosing between the ideal imaginaries of State and/or Market solutions. Widely presupposed as the only valid possibilities in both theory and practice, this stale dilemma covers up a real multitude of actually existing alternative approaches to governance practiced in civil society. State/Market approaches are identical in the way that they construct a ‘spectator’ role for communities, who are left to choose between their preferred set of rules and norms developed elsewhere. The concept of commoning governance offers an opportunity to break free of this stalemate. It creates a new role for citizens and their communities as ‘sparring partners’; who although they operate within the limits of current State/Market institutions, create new norms and rules against and beyond them. In the paper, we first expand on our understanding of commoning governance: re-designing governance arrangements to serve the common good. That is here understood in terms of (radical) democracy, solidarity and sustainable ecological relationships. Second, we illustrate how commoning efforts on the ground contribute to the reclaiming of the democratic imaginary as a political arena by zooming in to a case study of the three cities involved in civic-led network of German Food Policy Councils. Finally, we reflect on the empirical barriers that communities of commoning endure, and call on policymakers, planners and scholars to interrogate their own normative understandings of citizenship and democracy, and begin to recognize theoretical and latent possibilities by enabling commoning with new or re-designed institutions of governance.

Dismantling the status quo: promoting policies for health, well-being and equity: an IUHPE2022 prelude

The next international gathering of the global health promotion family will be in Montreal, in May 2022. The 24th IUHPE conference is themed ‘Promoting policies for health, well-being and equity’. Conference organizers have decided to transcend the ‘usual suspects’ rhetoric and frame a conference program that truly challenges these key notions for health promotion. In this contribution, members of the Canadian National and Global Scientific Committees reflect on the state of play and the opportunities ahead. We propose three themes as follows: (a) breaking news (the promise and opportunities for disruptions and tipping points, whether from pandemic health challenges, climate change, geopolitical shifts, social unrest or technological promise); (b) breaking free (from world-views that favor only market solutions, divisions between North and South, toward emancipatory decolonizing practices and knowledge systems); and (c) breaking through (disciplines, silos, boundaries and identities engrained in our practices and understandings for innovation.)

Experience with control systems and monitoring of the used computing resources of corporate HPC system

This article discusses modern server monitoring systems. The subject area under review concerns the control and management of high-performance computing systems (HPC). These systems are used in various branches of science and industry for modeling systems and their behavior in various conditions. The speed of the simulation depends on the applied technical solutions as part of the computing complex. These include the type of internal network, the number and types of computing nodes. For computing nodes, consider such parameters as the architecture and model of the processor, the amount of RAM. The features associated with the implementation of specific mathematical models that affect the speed of calculations are not considered in this article. The paper analyzes the existing market solutions and the main concepts used for the management and monitoring systems of such complexes. The systems under consideration are evaluated from an economic and technical point of view. For the available systems, a full-scale study of the cluster management and status monitoring capabilities is conducted. The set of parameters recorded by the monitoring system is taken based on the general architecture of the HPC and the approach to the administration of server systems. The practical part describes the experience of designing and implementing a promising management system. In the system being created, the main focus is on creating a management system. The justification for the need for a separate software product is given in the text of the article. Implementation issues in a specific program code and system environment are omitted, as they depend on the specific execution of the system. The task of creating your own monitoring system is considered insignificant, provided that existing solutions are available.
