The U.S. has transitioned from being the 20th-century global leader in civilian nuclear power to a nation searching for ways to revive its once-dominant nuclear enterprise. The future of U.S. civilian nuclear power transcends that of a science and technology issue and, fundamentally, is a policy issue. This is a policy paper that uses a nuclear power policy framework to analyze current and historical U.S. civilian nuclear power policy and to identify weaknesses and deficiencies that need to be overcome in order for the U.S. to (1) leverage advanced nuclear reactors as a domestic technology to meet energy security and reliability objectives under carbon constraints, (2) operationalize national security as a priority objective and (3) restore the U.S. as a major global exporter of nuclear technology. The results of this analysis indicate that the national security implications of U.S. nuclear power have been marginalized in general due to the domestic market challenges of competing with less expensive and oftentimes more socially acceptable technologies, as well as the international challenges of competing with state-owned nuclear enterprises. The results are then discussed and used for making three following policy recommendations: (1) conduct a U.S. nuclear industrial base review; (2) create a demand signal using U.S. military installations; and (3) shift away from a sell-side nuclear vendor model for global exports to a buy-side model brokered by a third-party integrator that can work with multiple U.S. nuclear partners.

(1) Background: Missing Middle (MM) housing may be critical to address decreasing housing affordability and to achieve critical density in transit-oriented neighborhoods; however, its production is in decline. We report on a case study of housing development around a new light-rail transit line in the Region of Waterloo, Canada, investigating the puzzle of how a residential building boom coincided with decreasing housing affordability. (2) Methods: Following participatory co-creation and communication of background research characterizing housing demand with stakeholder partners, we created a data narrative arguing that MM housing was desired by residents and profitable for developers and then used it to guide semi-structured interviews with planners and real estate industry stakeholders. Based on these interviews, we developed a qualitative system map and causal loop diagrams that demonstrate interactions between key actors (residents, brokers, planners, developers, and investors) as mediated by boundedly rational real estate demand expectations. (3) Results: Our interviews identify multi-faceted barriers, beyond demand perception, to MM housing development. Systems analysis illustrates how high-density, small-unit high-rise development can become locked in, concurrently locking out MM housing. (4) Conclusions: Our research identifies barriers to MM housing supply by articulating the systemic feedbacks between the planning and land/housing market realms and reveals key leverage points, empowering planners to develop policies that catalyze hoped-for housing market supply responses to increase housing affordability. Based on these findings, we suggest targeted interventions: multi-unit base residential zoning, MM site plan typologies, non-profit and co-op financing, unit-mix requirements, pre-build MM condo purchase by municipalities or non-profits, and MM demonstration projects.

Sustainable tourism is one of the key sectors in the South Baltic Sea Region (SBSR), which belongs to the role model for sustainability—the Baltic Sea Region (BSR). In this context, resilience, recovery and sustainability become key common threads calling for new approaches mitigating negative impacts, upscaling resilience capacity and boosting recovery in the post-pandemic era. The present work aims at revealing conceptual and practical pathways for policy makers and businesses in revitalizing sustainable tourism in the region by emphasizing cultural and creative industries (CCIs) as strong contributors to sustainable development and economic ecosystems, such as tourism. Tourism is also one of the key thematic areas of the smart specialization strategies (S3) in the SBSR. However, there is almost no link between CCIs’ potential for sustainable and resilient tourism and their contribution to the co-design and co-creation of S3. CCIs are rather absent agents in quadruple helix networks supporting S3 policy implementation. The literature on this topic is still premature, and represents a clear gap in knowledge. By virtue of these circumstances, the present research investigates how CCIs contribute and reveal new linkages between local assets, potential markets and societal challenges by engaging them as proven sustainable innovation and transition brokers in transnational quadruple helix partnerships following S3 policies in accordance with the sustainable development goals (SDGs), thus supporting sustainable and resilient tourism. Moreover, this paper aims at advocating for development of rural and peripheral regions, thus reducing the so-called “rural marginalization”. In addition, this paper also supports ongoing recent discussions on related vs. unrelated diversification policy within the S3 realm. Full article

Social enterprises often transmit pro-social values to their staff, volunteers, stakeholders, and communities. Research also shows that social enterprises can improve aspects of beneficiaries’ identity and self-worth. However, knowledge about identity-construction dynamics among social enterprises, their founders and other stakeholders, and the communities and cultures in which they are situated is undertheorized and fragmented across fields. This is attributable, at least in part, to the lack of a theory that can explain identity construction across micro-individual, meso-organizational, and macro-cultural levels. This study makes two major contributions. First, we advance a novel, multi-level theoretical framework for understanding identity construction based on assemblage theory. Second, we use that framework to interpret data from our ethnographic study of a social enterprise based in a Canadian fishing village. Our study reveals that the social enterprise actively curates identity resources from local culture and heritage and brokers those resources to stakeholders for their personal identity projects. It suggests that the impacts are greater for people with transitional or problematic identities. It also shows that identity-resource brokerage can result in generativity whereby staff and volunteers “pay it forward” with the effect of scaling the social impact of the enterprise. The findings support the usefulness of the identity-as-assemblage construct for understanding complex identity dynamics across multiple levels of analysis. They also open the door to a number of provocative research questions, including the role of narrative transmission in the flow of identity resources and a potential identity-mirroring role for social enterprise in shaping or reinforcing elements of place identity.

Small-scale farming production systems are integral drivers of global sustainability challenges and the climate crisis as well as a solution space for the transition to climate compatible development. However, mainstreaming agricultural emissions into a climate action agenda through integrative approaches, such as Climate Smart Agriculture (CSA), largely reinforces adaptation–mitigation dualism and pays inadequate attention to institutions’ linkage on the generation of externalities, such as Greenhouse Gas (GHG) emissions. This may undermine the effectiveness of local–global climate risk management initiatives. Literature data and a survey of small-scale farmers’ dairy feeding strategies were used in the simulation of GHG emissions. The effect of price risks on ecoefficiencies or the amount of GHG emissions per unit of produced milk is framed as a proxy for institutional feedbacks on GHG emissions and effect at scale. This case study on small-scale dairy farmers in western Kenya illustrates the effect of local-level and sectoral-level institutional constraints, such as market risks on decision making, on GHG emissions and the effectiveness of climate action. The findings suggest that price risks are significant in incentivising the adoption of CSA technologies. Since institutional interactions influence the choice of individual farmer management actions in adaptation planning, they significantly contribute to GHG spillover at scale. This can be visualised in terms of the nexus between low or non-existent dairy feeding strategies, low herd productivity, and net higher methane emissions per unit of produced milk in a dairy value chain. The use of the Sustainable Food Value Chain (SFVC) analytical lens could mediate the identification of binding constraints, foster organisational and policy coherence, as well as broker the effective mainstreaming of agricultural emissions into local–global climate change risk management initiatives. Market risks thus provide a systematic and holistic lens for assessing alternative carbon transitions, climate financing, adaptation–mitigation dualism, and the related risk of maladaptation, all of which are integral in the planning and implementation of effective climate action initiatives.

Recent research shows increasing efforts to unfold the potential of Cultural and Creative Industries (CCIs) for regions in order to pursue new sources of innovation, competitive edge and to manifest sustainable and inclusive growth paths driven by creativity. Due to its strong commitments to the Sustainable Development Goals (SDGs) of the United Nations, on the global level, the Baltic Sea Region (BSR) has become a role model in sustainable development. Yet, individual BSR countries face challenges in the implementation of those goals. In this light, by building on the intermediate results (2017–2020) of two EU Interreg projects—Creative Ports and CTCC—this research reveals CCIs’ potential for sustainable development avenues. The investigation is based on case study methodology underpinned by empirical data gathered from participating Small and Medium-Sized Enterprises (SMEs) and topical experts met during the projects’ implementation and study visits. The present multi-project applied research reduces the research-to-practice gap pertaining to the so far underestimated role of CCIs for supporting traditional SMEs in the implementation of their sustainable ideas. Once engaged into cross-sectoral collaboration with traditional SMEs, CCIs become important brokers—sustainable innovation drivers and enablers within regional ecosystems through contribution to environmentally responsible, socially equitable and economically feasible solutions for the business they work with. Thus, on the one hand, CCIs support SMEs in their transition towards more sustainable managerial performance. On the other hand, CCIs overcome disconnection and increase their recognition through new collaboration opportunities, thus providing them with new capitalization avenues on the regional and international level.

Sustainability transition projects (STPs) employ specialist knowledge and learning to lever changes for the communities with which they engage. Research into these forms of organizations often focuses on engagement practices and their relative success or failure to facilitate local transitions toward sustainability. What has attracted comparatively less attention, however, is how STPs develop their own sense of expertise in this role as a broker of Mode-2 knowledge or their own understanding about what it is that they are doing in facilitating community-scale changes. Privileging an emphasis on language-in-use research in organizational theory, this study analyzed the transcriptions of facilitated action research (AR) meetings of a case study STP by applying text mining methods in conjunction with a thematic analysis, the latter exploring insights gained across themes of governance, delivery, networks, challenges, and learning. The findings from these analyses are discussed with reference to how the case study STP staff group construes their work in the domain of sustainability and the generation and acquisition of relevant knowledge and learning in this specialized subsector of community development.

The Internet facilitates connections between a range of Dutch actors with a stake in the energy transition, including governments, environmental organizations, media outlets and corporations. These connections tease a hyperlink network affecting public access to information on energy transition issues. Despite its societal relevance, however, the characteristics of this network remain understudied. The main goals of this study are to shed some light on the topological characteristics of the Dutch energy transition hyperlink network and reveal the main topics discussed in the network. To do so, we longitudinally collected data from the interactions between key Dutch actors with a stake in the energy transition. Then, these data were analyzed by employing a mixed-method approach, social network analysis and topic modeling. The results of the social network analyses reveal the existence of a sparse network in which few private companies and associations emerge as the most authoritative actors and brokers. Furthermore, our analyses show substantial differences among the communication agendas of the organizations of the Dutch energy transition hyperlink network; while public institutions focus on global, national and local policy issues, private companies, associations and NGOs pay much more attention to employment issues.

The publish/subscribe model has gained prominence in the Internet of things (IoT) network, and both Message Queue Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP) support it. However, existing coverage-based fuzzers may miss some paths when fuzzing such publish/subscribe protocols, because they implicitly assume that there are only two parties in a protocol, which is not true now since there are three parties, i.e., the publisher, the subscriber and the broker. In this paper, we propose MultiFuzz, a new coverage-based multiparty-protocol fuzzer. First, it embeds multiple-connection information in a single input. Second, it uses a message mutation algorithm to stimulate protocol state transitions, without the need of protocol specifications. Third, it uses a new desockmulti module to feed the network messages into the program under test. desockmulti is similar to desock (Preeny), a tool widely used by the community, but it is specially designed for fuzzing and is 10x faster. We implement MultiFuzz based on AFL, and use it to fuzz two popular projects Eclipse Mosquitto and libCoAP. We reported discovered problems to the projects. In addition, we compare MultiFuzz with AFL and two state-of-the-art fuzzers, MOPT and AFLNET, and find it discovering more paths and crashes. Full article

This paper addresses the question of which function systemic intermediaries (here called ‘transition brokers’) can fulfil in the regional governance of implementing a circular economy (CE). Empirical research on this issue is scarce. The conclusion, based on a comparative case study of six Dutch regions, is that transition brokers fulfil the function of system orchestration. They can enhance processes of change, build alliances, help create the necessary preconditions, and develop impactful circular initiatives from a neutral standpoint. In a multi-stakeholder setting, transition brokers fulfil a variety of roles, depending on time period, content, and context. Executing these roles requires a number of specific competencies, varying from being entrepreneurially minded to daring to leave one’s comfort zone and being able to get the idea of CE accepted in a variety of businesses and organisations. From interviews held with key transition brokers in the six regions, it transpired that there is a clear division of labour between transition brokers vis-à-vis other key actors, among which the local government is included. These findings allow the design of a new model of regional governance in implementing CE from a system level perspective. It is recommended to perform similar case studies in other countries to generalise the results presented here. Full article

For years, the freight forwarding industry has been facing high levels of global competition. Accelerating this development, new and digital competitors are entering the market, striving to make freight logistics even faster, cheaper, and more predictable. Digitalization processes change traditional logistics businesses, leading to more efficient, flexible, and de-centrally organized logistics services. Sea freight operations, in particular, have the potential to better fulfill customer-specific requirements in competitive and complex environments by integrating digital technologies. Therefore, it is essential to understand how automating informational processes, such as freight brokering, affect business models in the logistics service industry. The present study qualitatively analyzed the case of FreightHub, a fourth-party logistics (4PL) sea freight agency, and compared its business model with traditional third-party logistics (3PL) business models. Applying a digital business model conceptualization, the present paper presents an extended framework for digital sea freight business models. In this line, the study contributes to theory and practice by refining business model research in the maritime transportation context, and providing managerial implications about the opportunities and threats of a digital transition in this industry.

The governance role of local renewable energy cooperatives (LRECs) in facilitating the energy transition remains under-scrutinized in the scholarly literature. Such a gap is puzzling, since LRECs are a manifestation of the current decentralization movement and yield a promising governance contribution to a ‘just energy transition.’ This paper presents a study of the governance roles of LRECs in the province of Limburg, the Netherlands. Building on existing work on the cooperative movement and energy governance, we, first, develop a conceptual framework for our analysis. The framework is built around three key interactions shaping these governance roles, between (1) LRECs and their (potential) members, (2) LRECs and the government and (3) LRECs with other LRECs. The results of an online survey and qualitative interviews with selected cooperatives led to the identification of five key governance roles that these cooperatives take up in the facilitation of the energy transition: (1) mobilizing the public, (2) brokering between government and citizens, (3) providing context specific knowledge and expertise, (4) initiating accepted change and (5) proffering the integration of sustainability. The paper concludes by reflecting on the relevance of our findings in this Dutch case for the broader ‘just transition’ movement. Full article

Background: Older adults in rural areas have unique transportation barriers to accessing medical care, which include a lack of mass transit options and considerable distances to health-related services. This study contrasts non-emergency medical transportation (NEMT) service utilization patterns and associated costs for Medicaid middle-aged and older adults in rural versus urban areas. Methods: Data were analyzed from 39,194 NEMT users of LogistiCare-brokered services in Delaware residing in rural (68.3%) and urban (30.9%) areas. Multivariable logistic analyses compared trip characteristics by rurality designation. Results: Rural (37.2%) and urban (41.2%) participants used services more frequently for dialysis than for any other medical concern. Older age and personal accompaniment were more common and wheel chair use was less common for rural trips. The mean cost per trip was greater for rural users (difference of $2910 per trip), which was attributed to the greater distance per trip in rural areas. Conclusions: Among a sample who were eligible for subsidized NEMT and who utilized this service, rural trips tended to be longer and, therefore, higher in cost. Over 50% of trips were made for dialysis highlighting the need to address prevention and, potentially, health service improvements for rural dialysis patients. Full article
