Urban Consolidation

AbstractRecently, many European local authorities have set up Urban Consolidation Centres (UCC) for dealing with challenges arising from the environmental and social impacts of logistical activities in urban contexts through shipment synchronisation and carrier coordination policies. However, the number of successful UCC projects led by local authorities in Europe is low, with most of the UCCs failing to achieve financial sustainability after the initial experimental phase, which is often heavily supported by public funds. In order to propose mechanisms that could favour the economic and financial sustainability of UCC systems, this research develops an adaptation of game-theoretic approaches to the problems of responsibility and cost allocation among stakeholders participating in a UCC delivery network. A solution based on the Shapley Value concept is employed to derive cost allocations; applications of the model to a real-world scenario are evaluated. An extensive sensitivity analysis shows that the proposed cost allocation rules can provide alternative arrangements, based on extended responsibility concepts, which can alleviate the burden on local authorities for the set up of UCCs. As such, results provide useful policy and practice implications on how to safeguard UCCs’ viability under different scenarios, including the outsourcing of the last-mile deliveries.

Abstract Conservation physiology represents a recently emerging arm of conservation science that applies physiological tools and techniques to understand and solve conservation issues. While a multi-disciplinary toolbox can only help to address the global biodiversity crisis, any field can face challenges while becoming established, particularly highly applied disciplines that require multi-stakeholder involvement. Gaining first-hand knowledge of the challenges that conservation physiologists are facing can help characterize the current state of the field and build a better foundation for determining how it can grow. Through an online survey of 468 scientists working at the intersection of physiology and conservation, we aimed to identify characteristics of those engaging in conservation physiology research (e.g. demographics, primary taxa of study), gauge conservation physiology’s role in contributing to on-the-ground conservation action, identify the perceived barriers to achieving success and determine how difficult any identified barriers are to overcome. Despite all participants having experience combining physiology and conservation, only one-third considered themselves to be ‘conservation physiologists’. Moreover, there was a general perception that conservation physiology does not yet regularly lead to tangible conservation success. Respondents identified the recent conceptualization of the field and the broader issue of adequately translating science into management action as the primary reasons for these deficits. Other significant barriers that respondents have faced when integrating physiology and conservation science included a lack of funding, logistical constraints (e.g. sample sizes, obtaining permits) and a lack of physiological baseline data (i.e. reference ranges of a physiological metric’s ‘normal’ or pre-environmental change levels). We identified 12 actions based on suggestions of survey participants that we anticipate will help deconstruct the barriers and continue to develop a narrative of physiology that is relevant to conservation science, policy and practice.

The Impact

We describe a multi-country, multi-stakeholder model for the accrual and use of nuclear weapons and illustrate the model’s value for addressing nuclear weapon proliferation issues using a historic Pacific Rim scenario. We instantiate the agent-based dynamic network model for information and belief diffusion using data from subject matter experts and data mined from open source news documents. We present the techniques that supported model instantiation. A key feature of this model and these techniques is enabling rapid model re-use through the ability to instantiate at two levels: generically and for specific cases. We demonstrate these generic and specific cases using a scenario regarding North Korea’s interest in nuclear weapons and the resulting impact on the Pacific Rim circa 2014, that is, prior to the fourth and fifth nuclear weapons tests by the Democratic People’s Republic of Korea. A key feature of this model is that it uses two levels of network interaction, the country level and the stakeholder level, thus supporting the inclusion of non-state actors and the assessment of complex scenarios. Using this model, we conducted virtual experiments in which we assessed the impact of alternative courses of action on the overall force posture and desire to develop and use nuclear weapons.

Purpose – The purpose of this article is to provide an overview of key issues and concepts related to discussions of the internet, its governance, and its multi-stakeholder model. Design/methodology/approach – The method adopted is to discuss definitions of internet, to identify the key characteristics of internet, to define the multi-stakeholder approach, and to discuss the results it has achieved. Findings – The article finds that the internet is different from other networks, albeit not exactly in the ways that are commonly mentioned, and it finds that the internet's current governance mechanisms can be improved, in particular by increasing the role of more traditional governance mechanisms such as intergovernmental organizations. Originality/value – The analysis and conclusions are not found in previous literature, and they are meant to provoke further research and discussion.

Abstract Given n vertices in a plane and UCAV going through each vertex once and only once and then coming back, the objective is to find the direction (heading) of motion in each vertex to minimize the smooth path of bounded curvature. This paper studies the headings of UCAV. First, the optimal headings for two vertices were given. On this basis, an n-player two-strategy game theoretic model was established. In addition, in order to obtain the mixed Nash equilibrium efficiently, n linear equations were set up. The simulation results demonstrated that the headings given in this paper are effective.

Sustainability Management

After highlighting the breadth and complexity of the concept of sustainability and highlighting the role of local authorities in sustainable development, this chapter aims to interpret how sustainability management can consider the concept of financial sustainability in the context of local governments. It does this through the following specific objectives: 1) defining financial sustainability, considering it not only autonomously, but in an integrated manner with respect to the typical sustainability dimensions (environmental, social, and economic) that are usually involved in the local authorities activity; 2) proposing the main stages of the sustainability cycle in the local authorities to highlight the key moments and the role of financial sustainability; 3) analyzing some aspects of financial indicators as tools for measuring the financial side of the sustainability profile of a local government. In order to reach the aim of the chapter, the research methodology followed is the literature review.

This chapter looks at central government’s role in directing the way in which local authorities enacted central-area redevelopment schemes. It shows how modernist ideas were sustained by a broadly consensual cross-party political culture in central government. It shows how the Joint Urban Planning Group, set up within the Ministry of Housing and Local Government, provided guidance to local authorities in how to form public–private partnerships to redevelop their city centres. The last section discusses the fate of these ideas during Labour’s first term after the 1964 election, and argues for an economic explanation of the initial reaction against modernist approaches to the built environment.
