Managing Development: EU and African Relations through the evolution of the Lomé and Cotonou Agreements
The relationship between the European Union 1 and Africa has been formalised since the beginning of the European integration project in the evolving YaoundĂ©, LomĂ© and now Cotonou Agreements. The relationship has shifted in line with the emerging global framework for neoliberal accumulation. This shift has involved the re-designingâ of developmental strategies and their âlocking-inâ in the long term. Theoretically, this global shift in the organisation of both production and social relations (including popular understandings) has been well documented and the changing dominant patterns of production in advanced industrial economies has been highlighted at length. However, this article aims to develop further the idea of âlocking-inâ, outlined in the work of Stephen Gill, and to place an increased emphasis on the phenomena of both re-designing and locking-in as they apply to the alteration of developmental strategies in Less Developed Countries (LDCs), among which those in Africa have suffered from extreme marginalisation and exploitation. This article reveals the often ignored role of the EU in this process. It argues that the EU, through its institutionalised link with Africa, has played a key role in re-designing developmental strategies to complement the global shift to neoliberal accumulation which, in its latest phase, is aimed particularly at the complex, multifaceted and increasingly integrated project to âlock-inâ the gains of capital over labour on a global scale. The article begins with a brief introduction to the complementary projects of âre-designingâ and âlocking-inâ before considering these against the historical evolution of the LomĂ© and Cotonou relationship
Thriving not just surviving: A review of research on teacher resilience
Retaining teachers in the early stages of the profession is a major issue of concern in many countries. Teacher resilience is a relatively recent area of investigation which provides a way of understanding what enables teachers to persist in the face of challenges and offers a complementary perspective to studies of stress, burnout and attrition. We have known for many years that teaching can be stressful, particularly for new teachers, but little appears to have changed. This paper reviews recent empirical studies related to the resilience of early career teachers. Resilience is shown to be the outcome of a dynamic relationship between individual risk and protective factors. Individual attributes such as altruistic motives and high self-efficacy are key individual protective factors. Contextual challenges or risk factors and contextual supports or protective factors can come from sources such as school administration, colleagues, and pupils. Challenges for the future are to refine conceptualisations of teacher resilience and to develop and examine interventions in multiple contexts. There are many opportunities for those who prepare, employ and work with prospective and new teachers to reduce risk factors and enhance protective factors and so enable new teachers to thrive, not just survive
Bodily attractiveness and egalitarianism are negatively related in males.
Ancestrally, relatively attractive individuals and relatively formidable males may have had reduced incentives to be egalitarian (i.e., to act in accordance with norms promoting social equality). If selection calibrated one's egalitarianism to one's attractiveness/formidability, then such people may exhibit reduced egalitarianism ("observed egalitarianism") and be perceived by others as less egalitarian ("perceived egalitarianism") in modern environments. To investigate, we created 3D body models of 125 participants to use both as a source of anthropometric measurements and as stimuli to obtain ratings of bodily attractiveness and perceived egalitarianism. We also measured observed egalitarianism (via an economic "dictator" game) and indices of political egalitarianism (preference for socialism over capitalism) and "equity sensitivity." Results indicated higher egalitarianism levels in women than in men, and moderate-to-strong negative relationships between (a) attractiveness and observed egalitarianism among men, (b) attractiveness and perceived egalitarianism among both sexes, and (c) formidability and perceived egalitarianism among men. We did not find support for two previously-reported findings: that observed egalitarianism and formidability are negatively related in men, and that wealth and formidability interact to explain variance in male egalitarianism. However, this lack of support may have been due to differences in variable measurement between our study and previous studies
Singing and COPD: development, implementation and evaluation of a resource to support home practice and disease self-management
Aim
To explore the use of a singing for health self-management resource for home practice within a programme of regular group singing for people with COPD.
Rationale
Research suggests that perceived symptoms of COPD can be improved through promoting self-efficacy and self-management of the condition. Previous literature on singing for breathing includes little detailed reference to any resources used to contribute to such improvement. This paper describes and evaluates a resource designed to address this.
Approach
The Singing for Better Breathing (SfBB) resource comprises a DVD of 13 films and accompanying handbook. It was developed as a practical tool for participants to use at home, as an adjunct to health education provided in an existing singing for COPD research project. The films progress through physical and vocal warm-ups plus songs which gradually demand greater vocal production and breath control. Participants were encouraged to keep diaries to record their experiences of using the resource. These were analysed using thematic analysis, supplemented by individual telephone interviews following the final session. With the onset of the Covid-19 pandemic, the resource was made available online.
Findings
Ten participants completed diary entries and were interviewed. All spoke positively regarding the format of the resource, and the majority found the songs to be engaging and uplifting. The use of singing as an exercise to promote breath control was reflected in a desire to demonstrate their achievements as well as the songs they had been able to sing at home.
Discussion and conclusion
The resource has continued to be popular, evidenced by its online uptake globally. Future related research should include a more detailed exploration of how those living with long-term health conditions might engage with and benefit from a singing for health resource to promote self-management
Non-linear resistivity and heat dissipation in monolayer graphene
We have experimentally studied the nonlinear nature of electrical conduction
in monolayer graphene devices on silica substrates. This nonlinearity manifests
itself as a nonmonotonic dependence of the differential resistance on applied
DC voltage bias across the sample. At temperatures below ~70K, the differential
resistance exhibits a peak near zero bias that can be attributed to
self-heating of the charge carriers. We show that the shape of this peak arises
from a combination of different energy dissipation mechanisms of the carriers.
The energy dissipation at higher carrier temperatures depends critically on the
length of the sample. For samples longer than 10um the heat loss is shown to be
determined by optical phonons at the silica-graphene interface.Comment: 4 pages, 4 figure

Phenolic cutter for machining foam insulation
Pre-pregged fiber glass is an efficient abrasive for machining polystyrene and polyurethane foams. It bonds easily to any cutter base made of aluminum, steel, or phenolic, is inexpensive, and is readily available
Molecules, ices and astronomy
Molecules in interstellar gas and in interstellar ices play a fundamental role in astronomy. However, the formation of the simplest molecule, molecular hydrogen, is still not fully understood. Similarly, although interstellar ice analogues have received much attention in the laboratory, the evolution of ices in the interstellar medium still requires further study. At UCL we have developed two separate experiments to address these issues and explore the following questions: How is H formed on dust-grain surfaces? What is the budget between internal, kinetic and surface energies in the formation process? What are the astronomical consequences of these results? For ices, we ask: How do molecules desorb from pure and from mixed ices in regions warmed by newly formed stars? What can molecules released from ices tell us about the star-formation process? We put our results in the context of other laboratory work and we describe their application to current problems in astronomy
