    The Political Economy of State-led Energy Transformations: Lessons from Solar PV in Kenya and China

    Amid talk of the need for a low carbon ‘clean energy revolution’ to address the challenges of energy poverty and climate change, there is growing academic and policy interest in understanding the role of key actors that are expected to enable transitions and transformations towards a low carbon economy in a pro-poor way. Within the socio-technical transitions literature, there has been increased interest in “the state” as the primary actor with the responsibility, authority and capacity to address these issues. But understanding the role of the state in energy transformations requires an appreciation of context: what is possible given enormous differences in capacity and resources, autonomy and uneven access to different energy sources and technologies. Which technologies and energy systems receive support, whose energy needs get prioritised and which actors are charged with the responsibility for meeting energy needs are a function of very different decision-making processes, political systems and political economies. Taking the case of support to solar PV in China and Kenya, we develop a political economy analysis of state-led energy transformations which seeks to explore how different aspects of statehood impact upon the nature and prospects of the sorts of transformations now urgently required of energy systems. We do so by examining political economy dynamics in relation to: (i) the organisation of the state; (ii) the political nature of the state; and (iii) the state in the global political economy. This raises questions about the viability and desirability of generic prescriptions for “managed transitions” in light of such diversity in state forms and functions, the different ways in which they interact with energy systems and the evident limits of the sorts of transitions and transformations that states alone can steer, manage or impose. It thus speaks to broader debates about the politics of “care” vs. “control” in transformations to sustainability.ESR

    The politics of community in contemporary British fiction

    Get PDF
    This thesis draws on the work of philosopher Jean-Luc Nancy to propose ‘community’ as a conceptual and hermeneutical figure that opens up productive possibilities in the study of contemporary British literature. Community is advanced as a form of political ontology, which moves beyond contingent appearance toward radical possibilities for transformation in the current political landscape. Particular attention is paid to the way in which community is ‘put to work’ as part of the operation of the capitalist state, where community emerges as a central site of political contestation. Community is demonstrated as offering ways of rethinking the figure of ‘politics’ itself, opening avenues for developing its meaning through emergent theories of ‘gender’, the ‘queer’ and ‘trans’. Community is addressed in the space of literature and representation, where Nancy’s figure of ‘myth interrupted’ is presented as an important dimension of communitarian thought. Through interrogating the representability of community, its mythic foundations are subjected to a process of radical openness that allows for a vibrant and dynamic form of community to emerge. Situating these capacities in the works of authors Jackie Kay, Jon McGregor and Ali Smith, literature is presented as a singular space through which communitarian possibility can be glimpsed. The conceptual figures of ‘death’, ‘gender transformation’ and ‘magic’ are proposed as offering new possibilities in our understanding of community, demonstrating how literature can offer productive and innovative ways of reimagining our understanding of community in the contemporary moment. In this way, this thesis contributes to ongoing debates about the significance of ‘community’ in contemporary thought, drawing on literature to propose the ‘politics of community’ as a productive avenue for addressing this

    Testbeam studies of pre-prototype silicon strip sensors for the LHCb UT upgrade project

    Full text link
    The LHCb experiment is preparing for a major upgrade in 2018-2019. One of the key components in the upgrade is a new silicon tracker situated upstream of the analysis magnet of the experiment. The Upstream Tracker (UT) will consist of four planes of silicon strip detectors, with each plane covering an area of about 2 m2^2. An important consideration of these detectors is their performance after they have been exposed to a large radiation dose. In this article we present test beam results of pre-prototype n-in-p and p-in-n sensors that have been irradiated with fluences up to 4.0×10144.0\times10^{14} neqn_{\rm eq} cm2^{-2}.Comment: 25 pages, 20 figure

    Occurrence of delirium is severely underestimated in the ICU during daily care

    Delirium is associated with prolonged intensive care unit (ICU) stay and higher mortality. Therefore, the recognition of delirium is important. We investigated whether intensivists and ICU nurses could clinically identify the presence of delirium in ICU patients during daily care. All ICU patients in a 3-month period who stayed for more than 48 h were screened daily for delirium by attending intensivists and ICU nurses. Patients were screened independently for delirium by a trained group of ICU nurses who were not involved in the daily care of the patients under study. The Confusion Assessment Method for the ICU (CAM-ICU) was used as a validated screening instrument for delirium. Values are expressed as median and interquartile range (IQR; P25-P75). During the study period, 46 patients (30 male, 16 female), median age 73 years (IQR = 64-80), with an ICU stay of 6 days (range 4-11) were evaluated. CAM-ICU scores were obtained during 425 patient days. Considering the CAM-ICU as the reference standard, delirium occurred in 50% of the patients with a duration of 3 days (range 1-9). Days with delirium were poorly recognized by doctors (sensitivity 28.0%; specificity 100%) and ICU nurses (sensitivity 34.8%; specificity 98.3%). Recognition did not differ between hypoactive or active status of the patients involved. Delirium is severely under recognized in the ICU by intensivists and ICU nurses in daily care. More attention should be paid to the implementation of a validated delirium-screening instrument during daily ICU car

    Fascicles and the interfascicular matrix show decreased fatigue life with ageing in energy storing tendons

    Tendon is composed of rope-like fascicles bound together by interfascicular matrix (IFM). The IFM is critical for the function of energy storing tendons, facilitating sliding between fascicles to allow these tendons to cyclically stretch and recoil. This capacity is required to a lesser degree in positional tendons. We have previously demonstrated that both fascicles and IFM in energy storing tendons have superior fatigue resistance compared with positional tendons, but the effect of ageing on the fatigue properties of these different tendon subunits has not been determined. Energy storing tendons become more injury-prone with ageing, indicating reduced fatigue resistance, hence we tested the hypothesis that the decline in fatigue life with ageing in energy storing tendons would be more pronounced in the IFM than in fascicles. We further hypothesised that tendon subunit fatigue resistance would not alter with ageing in positional tendons. Fascicles and IFM from young and old energy storing and positional tendons were subjected to cyclic fatigue testing until failure, and mechanical properties were calculated. The results show that both IFM and fascicles from the SDFT exhibit a similar magnitude of reduced fatigue life with ageing. By contrast, the fatigue life of positional tendon subunits was unaffected by ageing. The age-related decline in fatigue life of tendon subunits in energy storing tendons is likely to contribute to the increased risk of injury in aged tendons. Full understanding of the mechanisms resulting in this reduced fatigue life will aid in the development of treatments and interventions to prevent age-related tendinopathy
