Comprehensive Stormwater Management Plans on University Campuses: Challenges and Opportunities
Under the Clean Water Act, Philadelphia is required to reduce its Combined Sewer Overflow volume by 85% (PWD, 2009). Other cities have constructed massive underground storage tunnels to capture overflows, but the Philadelphia Water Department has proposed a plan that places a fee on impervious cover and relies heavily on green infrastructure. There is an opportunity for the University of Pennsylvania to become a model institution for stormwater management and also to save money on Philadelphia’s stormwater charge. Sporadic green infrastructure projects will have some effect, but in order to be as efficient as possible in meeting the two aforementioned goals, it is necessary to coordinate green infrastructure projects through a stormwater management plan. The University of Pennsylvania is in the process of developing such a plan. This study describes the current stormwater management efforts being made at the University of Pennsylvania and examines the efforts of other universities in developing their own stormwater management plans, with the goal of gleaning innovative practices that can be recreated at other universities. While it is too early to determine which stormwater plans have achieved long-term success, a survey given to nine universities reveals common themes between plans. A common framework for a campus stormwater management plan was found to take inventory of existing infrastructure and campus conditions, develop a list of acceptable best management practices, develop an educational and outreach component, and develop an operation and maintenance v schedule for green infrastructure technologies. The most innovative plan in the study belongs to the Georgia Institute of Technology, which creates an Eco-Commons corridor on the most ecologically sensitive parts of campus, in which development is severely limited. Stormwater goals are met by using a regional approach, as opposed to a project-by-project approach, increasing the flexibility of new development on campus. Villanova University has also developed an excellent BMP research park, which also serves as an outreach component. The University of Pennsylvania should develop a plan that considers emulating these innovative practices and adding them to the common framework
Blowing policy bubbles: rethinking emissions targets and low-carbon energy policies in the UK
The issue of proportionality is central to climate policy debates about setting targets for the reduction of greenhouse gas emissions and the development of low-carbon energy. In effect, these debates centre on whether the perceived social costs outweigh the benefits of policies and, if not, whether this may lead to over-investment or ‘policy bubbles’. Political attention, agenda setting and policy image are all crucial drivers of ambitious policy formation, as seen in the case of the United Kingdom's (UK) Climate Change Act (2008). However, as political salience waned and economic depression dragged on, the cost of long-term climate targets have been reconsidered. Based on documentary analysis and 33 interviews with central political actors, this article presents a detailed account of how economic arguments have been used to reinterpret and challenge policies, using the heuristics of ‘over-investment’ and ‘policy bubbles’. Ultimately, arguments about proportionality hinge on which costs and benefits are considered. In the UK, economic and technical framings are typically prioritised, but they do not explain contradictory and politically motivated policy decisions. We discuss these dynamics within the context of maturing renewable energy technologies, high energy prices and the UK's cross-party consensus approach to climate politics
Unit-cell for dual-circular polarisation reflectarrays
International audience—A new unit-cell composed of two layers for dual-CP reflectarrays is proposed for the first time with the unique capability to reflect independently and simultaneously the two incident circular polarisations at the same frequency. The experimental results demonstrate that this unit-cell exhibits a 3.8% bandwidth around 8.4 GHz for a phase resolution better than 1.92 bits in LHCP and in RHCP. As a first step towards a reflectarray in dual-CP, this innovative unit-cell is studied in an array configuration. To increase the value of the maximum incidence angle up to 30°, a matching dielectric layer is placed over the cell
Secure and equal access to land for all: Lessons on land governance and climate resilience from Dar es Salaam, Tanzania
Secure land and property rights are essential for improving the livelihoods of the poor and ending poverty. Effective and equitable land governance can also contribute to economic development, domestic resource mobilisation and climate change resilience. Promoting fair and transparent land tenure systems should therefore be a priority for national governments

COPe-support - a multi-component digital intervention for family carers for people affected by psychosis: study protocol for a randomized controlled trial.
BACKGROUND: Psychosis often causes significant distress and impacts not only in the individuals, but also those close to them. Many relatives and friends ('carers') provide long-term support and need resources to assist them. We have co-produced a digital mental health intervention called COPe-support (Carers fOr People with Psychosis e-support) to provide carers with flexible access to high quality psychoeducation and interactive support from experts and peers. This study evaluates the effectiveness of COPe-support to promote mental wellbeing and caregiving experiences in carers. METHODS: This study is a single-blind, parallel arm, individually randomized controlled trial (RCT) comparing COPe-support, with attention control. Both groups continue to receive usual care. COPe-support provides interactive web-based psychoeducation on psychosis-related issues, wellbeing-promotion and network support through forums. The attention-control is a non-interactive online information resource pack. Carers living in England are eligible if they provide at least weekly support to a family member or close friend affected by psychosis, and use internet communication (including emails) daily. All trial procedures are run online, including collection of outcome measurements which participants will directly input into our secure platform. Following baseline assessment, a web-based randomization system will be used to allocate 360 carers to either arm. Participants have unlimited access to the allocated condition for 40 weeks. Data collection is at three time points (10, 20, and 40 weeks after randomization). Analyses will be conducted by trial statisticians blinded to allocation. The primary outcome is mental wellbeing measured by Warwick Edinburgh Mental Wellbeing Scale (WEMWBS), at 20 weeks. As well as an intention-to-treat analysis, a complier average causal effect (CACE) analysis will be conducted to estimate the intervention effect in participants who have accessed COPe-support content twice or more. The secondary objectives and analysis will examine other health and caregiving-related outcomes and explore mechanisms. In a process evaluation, we will interview 20% of the intervention arm participants regarding the acceptability of COPe-support. We will explore in detail participants' usage patterns. DISCUSSION: The results of this trial will provide valuable information about the effectiveness of COPe-support in promoting wellbeing and caregiving experiences in carers. TRIAL REGISTRATION: The RCT is registered with the Current Controlled Trials registration (ISRCTN 89563420, registration date: 02/03/2018)
Can national policy blockages accelerate the development of polycentric governance? Evidence from climate change policy in the United Kingdom
Many factors can conspire to limit the scope for policy development at the national level. In this paper, we consider whether blockages in national policy processes − resulting for example from austerity or small state political philosophies − might be overcome by the development of more polycentric governance arrangements. Drawing on evidence from three stakeholder workshops and fifteen interviews, we address this question by exploring the United Kingdom’s recent retrenchment in the area of climate change policy, and the ways in which its policy community have responded. We identify two broad strategies based on polycentric principles: ‘working with gatekeepers’ to unlock political capital and ‘collaborate to innovate’ to develop policy outputs. We then empirically examine the advantages that these actions bring, analysing coordination across overlapping sites of authority, such as those associated with international regimes, devolved administrations and civic and private initiatives that operate in conjunction with, and sometimes independently of, the state. Despite constraining political and economic factors, which are by no means unique to the UK, we find that a polycentric climate policy network can create opportunities for overcoming central government blockages. However, we also argue that the ambiguous role of the state in empowering but also in constraining such a network will determine whether a polycentric approach to climate policy and governance is genuinely additional and innovative, or whether it is merely a temporary ‘sticking plaster’ for the retreat of the state and policy retrenchment during austere times

Informing the development of services supporting self-care for long term mental health conditions: A mixed method study of community based mental health initiatives in England
Background
Supporting self-care is being explored across health care systems internationally as an approach to improving care for long term conditions in the context of ageing populations and economic constraint. UK health policy advocates a range of approaches to supporting self-care, including the application of generic self-management type programmes across conditions. Within mental health, the scope of self-care remains poorly conceptualised and the existing evidence base for supporting self-care is correspondingly disparate. This paper aims to inform the development of support for self-care in mental health by considering how generic self-care policy guidance is implemented in the context of services supporting people with severe, long term mental health problems.
Methods
A mixed method study was undertaken comprising standardised psychosocial measures, questionnaires about health service use and qualitative interviews with 120 new referrals to three contrasting community based initiatives supporting self-care for severe, long term mental health problems, repeated nine months later. A framework approach was taken to qualitative analysis, an exploratory statistical analysis sought to identify possible associations between a range of independent variables and self-care outcomes, and a narrative synthesis brought these analyses together.
Results
Participants reported improvement in self-care outcomes (e.g. greater empowerment; less use of Accident and Emergency services). These changes were not associated with level of engagement with self-care support. Level of engagement was associated with positive collaboration with support staff. Qualitative data described the value of different models of supporting self-care and considered challenges. Synthesis of analyses suggested that timing support for self-care, giving service users control over when and how they accessed support, quality of service user-staff relationships and decision making around medication are important issues in supporting self-care in mental health.
Conclusions
Service delivery components – e.g. peer support groups, personal planning – advocated in generic self-care policy have value when implemented in a mental health context. Support for self-care in mental health should focus on core, mental health specific qualities; issues of control, enabling staff-service user relationships and shared decision making. The broad empirical basis of our research indicates the wider relevance of our findings across mental health settings
“How can you live like that?”: energy vulnerability and the dynamic experience of fuel poverty in the UK
Recent evidence documents a dramatic reduction in average direct UK household energy consumption between 2005 and 2011 (ONS, 2013). This in a time when energy prices rise yearly, and incomes are static or declining. Meanwhile, the government's definition of fuel poverty is changing following the Hills review. Here we draw on qualitative data to explore the experience of fuel poverty in the UK and to suggest a dynamic set of qualitative indicators for household vulnerability. Among fifteen diverse participants from across the UK, a substantive shift has taken place in people's ability to cope, and their need to compromise on basic needs. In our data we identify six dimensions of energy vulnerability for the fuel poor, including the three commonly cited in the literature (quality of dwelling fabric, energy costs and supply issues, and stability of household income). Tenancy relations, social relations within the household and outside, and ill health also play a mediating role in households' ability to cope. Our findings problematize the existing measures of fuel poverty, and suggest that the emerging concept of energy vulnerability provides a useful lens with which to understand the dynamic nature of fuel poverty at the household level
