The Membership Journey: Understanding and Boosting Membership Today

This is the final version. Available from the University of Sheffield via the link in this record.Membership is an important part of the working of a healthy democratic system. Yet in a world where individual and sporadic engagement is becoming the norm, membership of political organisations is increasingly unusual. • Membership organisations now regularly confront challenges in recruiting, activating and retaining members. • Membership can be usefully understood as a journey, not a series of disconnected stages. This journey is underpinned by three factors: 1) MOTIVATION 2) PROCESS 3) TRIGGER • By understanding these factors, organisations can better recruit, activate and retain members. • Organisations wishing to address membership challenges can take the following actions: * Understanding motivation: collect and communicate members’ reasons for joining; feedback members on the outcomes of their campaigning activity; target specific events around specific motivations; thank members for engaging and volunteering time * Understanding process: conduct mystery shopper exercises to see how easy it is to join and get involved with your organisation; install a direct debit system by default; share best practice in recruitment, retention and activation; offer lifetime membership; highlight motivations for joining and remaining in the party online * Understanding triggers: identify existing events, activities and catalysts for joining or taking action in an organisation, piggyback on external events and campaigns that might drive people to your organisation; orchestrate events that might cultivate engagement and boost membership; mainstream membership recruitment and engagement as a part of ongoing activities; ensure that triggers are the only cause of membership lossThis report was produced as part of a wider research project ‘Renewing Party Politics’ that is funded by the ESRC (Grant number: ES/N01667X/1)

Reflexivity of the translation-dilation algebras on L^2(R)

The hyperbolic algebra A_h, studied recently by Katavolos and Power, is the weak star closed operator algebra on L^2(R) generated by H^\infty(R), as multiplication operators, and by the dilation operators V_t, t \geq 0, given by V_t f(x) = e^{t/2} f(e^t x). We show that A_h is a reflexive operator algebra and that the four dimensional manifold Lat A_h (with the natural topology) is the reflexive hull of a natural two dimensional subspace.Comment: 10 pages, no figures To appear in the International Journal of Mathematic

Crop residue conservation during fallow and erosion risk in west central Saskatchewan

Non-Peer ReviewedSummerfallow is considered to be a necessary practice to replenish soil moisture reserves in much of west central Saskatchewan. Unfortunately, this practice has been largely responsible for severe erosion in the past. Recently many farmers have attempted to keep more crop residue on the soil surface, by using herbicides and wide blade cultivators to control weeds during the fallow period. Much of the increase in these practices has been due to assistance programs provided by PFRA, Saskatchewan Agriculture (e.g., Save Our Soils (SOS) program), Ducks Unlimited and other organizations. This paper looks at the effectiveness of these projects in mainta1n1ng crop residue to minimize erosion. Included are evaluations of weed control, costs, subsequent crop yields and farmer perceptions. Results of a crop residue survey are also presented. This survey provides a good comparison with the project fields. It also enables one to forecast erosion potential for the following winter, spring, and summer seasons. While the paper focuses mainly on 1988 activities, it should be noted that similar work was done in 1986-87

Conquering the great divide: Rural mothers of children with chronic health conditions accessing specialist medical care for their children

© 2019 Australian College of Nursing Ltd Background: Globally, the number of children with chronic health conditions (CHCs) is increasing and mothers are mostly responsible for their care. Aim: Few studies have focused on rural mothers and their experiences of sourcing health care for their children who have CHCs. The purpose of this study was to explore these experiences. Method: Using a phenomenological approach, semi-structured interviews were conducted in early 2018. The Consolidated criteria for Reporting Qualitative research (COREQ) guidelines were followed. Sixteen rural mothers were interviewed regarding their experiences of accessing health care to provide optimal management of their children's CHC. Findings: Thematic analysis of resulting data revealed the overarching theme ‘Conquering the great divide’. From this overarching theme, four themes emerged. This paper focuses on the first theme, ‘Heading to the big smoke: access’. Discussion: Rural mothers felt challenged accessing health care for their children in the major cities whilst also maintaining routine family life back home. Conclusion: Understanding these rural women's experiences could assist health care professionals to develop strategies to facilitate rural mothers accessing services for their children with a CHC

Monitoring digital election campaigns: assessing the transparency ecosystem in the United Kingdom

Digital election campaigning has undergone increased levels of scrutiny in recent years, with numerous calls for improved transparency. One key innovation has been the creation of online advertising archives offered by social media platforms such as Facebook, Google, and Snapchat. In this article, we compare what we know about digital campaigning in the United Kingdom from official election returns and Facebook and Google’s online advertising archives. We analyse whether both transparency sources provide agreed standards of completeness, consistency, accuracy, and accessibility. We find that – despite the United Kingdom having an effectively world-leading transparency regime – this is not the case. We therefore consider a number of potential reforms to increase knowledge of the workings of campaigns at the national level

Effects of past climate variability on fire and vegetation in the cerrãdo savanna of the Huanchaca Mesetta, NE Bolivia

Cerrãdo savannas have the greatest fire activity of all major global land-cover types and play a significant role in the global carbon cycle. During the 21st century, temperatures are projected to increase by ∼ 3 ◦C coupled with a precipitation decrease of ∼ 20 %. Although these conditions could potentially intensify drought stress, it is unknown how that might alter vegetation composition and fire regimes. To assess how Neotropical savannas responded to past climate changes, a 14 500-year, high-resolution, sedimentary record from Huanchaca Mesetta, a palm swamp located in the cerrãdo savanna in northeastern Bolivia, was analyzed with phytoliths, stable isotopes, and charcoal. A nonanalogue, cold-adapted vegetation community dominated the Lateglacial–early Holocene period (14 500–9000 cal yr BP, which included trees and C3 Pooideae and C4 Panicoideae grasses. The Lateglacial vegetation was fire-sensitive and fire activity during this period was low, likely responding to fuel availability and limitation. Although similar vegetation characterized the early Holocene, the warming conditions associated with the onset of the Holocene led to an initial increase in fire activity. Huanchaca Mesetta became increasingly firedependent during the middle Holocene with the expansion of C4 fire-adapted grasses. However, as warm, dry conditions, characterized by increased length and severity of the dry season, continued, fuel availability decreased. The establishment of the modern palm swamp vegetation occurred at 5000 cal yr BP. Edaphic factors are the first-order control on vegetation on the rocky quartzite mesetta. Where soils are sufficiently thick, climate is the second-order control of vegetation on the mesetta. The presence of the modern palm swamp is attributed to two factors: (1) increased precipitation that increased water table levels and (2) decreased frequency and duration of surazos (cold wind incursions from Patagonia) leading to increased temperature minima. Natural (soil, climate, fire) drivers rather than anthropogenic drivers control the vegetation and fire activity at Huanchaca Mesetta. Thus the cerrãdo savanna ecosystem of the Huanchaca Plateau has exhibited ecosystem resilience to major climatic changes in both temperature and precipitation since the Lateglacial period

RKKY interaction between adsorbed magnetic impurities in graphene: Symmetry and strain effects

The growing interest in carbon-based spintronics has stimulated a number of recent theoretical studies on the RKKY interaction in graphene, with the aim of determining the most energetically favourable alignments between embedded magnetic moments. The RKKY interaction in undoped graphene decays faster than expected for conventional two-dimensional materials and recent studies suggest that the adsorption configurations favoured by many transition-metal impurities may lead to even shorter ranged decays and possible sign-changing oscillations. Here we show that these features emerge in a mathematically transparent manner when the symmetry of the configurations is included in the calculation. Furthermore, we show that by breaking the symmetry of the graphene lattice, via uniaxial strain, the decay rate, and hence the range, of the RKKY interaction can be significantly altered. Our results suggest that magnetic interactions between adsorbed impurities in graphene can be manipulated by careful strain engineering of such systems.Comment: 12 pages, 6 figures, submitte

Experimental Observation of Energy Modulation in Electron Beams Passing Through Terahertz Dielectric Wakefield Structures

We report observation of a strong wakefield induced energy modulation in an energy-chirped electron bunch passing through a dielectric-lined waveguide. This modulation can be effectively converted into a spatial modulation forming micro-bunches with a periodicity of 0.5 - 1 picosecond, hence capable of driving coherent THz radiation. The experimental results agree well with theoretical predictions.Comment: v3. Reviewers' suggestions incorporated. Accepted by PR
