Dynamic and complex microclimate responses to warming and grazing manipulations

Synthesis efforts that identify patterns of ecosystem response to a suite of warming manipulations can make important contributions to climate change science. However, cross-study comparisons are impeded by the paucity of detailed analyses of how passive warming and other manipulations affect microclimate. Here we document the independent and combined effects of a common passive warming manipulation, open-top chambers (OTCs), and a simulated widespread land use, clipping, on microclimate on the Tibetan Plateau. OTCs consistently elevated growing season averaged mean daily air temperature by 1.0-2.0 degrees C, maximum daily air temperature by 2.1-7.3 degrees C and the diurnal air temperature range by 1.9-6.5 degrees C, with mixed effects on minimum daily air temperature, and mean daily soil temperature and moisture. These OTC effects on microclimate differ from reported effects of a common active warming method, infrared heating, which has more consistent effects on soil than on air temperature. There were significant interannual and intragrowing season differences in OTC effects on microclimate. For example, while OTCs had mixed effects on growing season averaged soil temperatures, OTCs consistently elevated soil temperature by approximately 1.0 degrees C early in the growing season. Nonadditive interactions between OTCs and clipping were also present: OTCs in clipped plots generally elevated air and soil temperatures more than OTCs in nonclipped plots. Moreover, site factors dynamically interacted with microclimate and with the efficacy of the OTC manipulations.These findings highlight the need to understand differential microclimate effects between warming methods, within warming method across ecosystem sites, within warming method crossed with other treatments, and within sites over various timescales. Methods, sites and scales are potential explanatory variables and covariables in climate warming experiments. Consideration of this variability among and between experimental warming studies will lead to greater understanding and better prediction of ecosystem response to anthropogenic climate warming.

Experiences and desires of people with tetraplegia living with and without electronic aids to daily living: an Irish focus group study

This qualitative descriptive study explores the lived experience for persons with a high cervical spinal cord injury who have Electronic Aids to Daily Living (EADLs), and for persons who have no EADLs. Fifteen people with cervical spinal cord injuries attended four focus groups. Data analysis uncovered a novel framework of several themes that were organised into three categories: experiences, desires and meanings of living with EADL. Users’ and non users’ groups revealed homogenous themes. Experiences and desires are explored further in this paper. Themes within the category of experiences included: EADL devices, supply support and training, abandonment, mouthsticks and powered wheelchairs. Desires included: simple stuff, reliability, aesthetics and voice activation. Findings offer valuable personal insights about life with EADL to be considered by all involved with EADL.

序破急 Jo-Ha-Kyu: enticement - crux - consolidation. From study to learning: Process drama projects in the Japanese English language university classroom

This dissertation investigates how social issues can be explored through process drama projects in the Japanese university English as a Foreign Language classroom context. The trajectory of this dissertation moves along a traditional Noh three part macro-continuum, called Jo-Ha-Kyu, interpreted as enticement, crux and consolidation. Within these three parts, there are six further divisions. Part I consists of three sections: Section I, the introduction, sets the backdrop for the entire dissertation, that of Japan, and aims to draw the reader into its culturally unique and specific world. This section outlines the rationale for placing the ethnographer at the centre of the research, and presents Japan through the eyes of the writer. Section II outlines relevant Japanese cultural norms, mores and values, the English educational landscape of Japan and an overview of theatre in Japan and its possible influences on the Japanese university student today. Section III provides three literature reviews: second language acquisition, drama in education to process drama, and Content Language Integrated Learning. In Part 2, Sections IV and V respectively consist of the research methodology and the action research at the core of this dissertation. Section IV describes the case of Kwansei Gakuin University, then explains the design of the process drama curricula. Section V details the three-process drama projects based around the three social issues at the centre of this dissertation. There is also a description of an extra project that of the guest lecturer project. The ultimate goals of all four projects were to change motivation through English in a CLIL context, to develop linguistic spontaneity and to deepen emotional engagement with the themes. Part 3 serves to reflect upon the viability of using process drama in the Japanese university curriculum, and to critically self-reflect on the project as a whole.

History, revolution and the British popular novel: historical fiction in the romantic age

“History, Revolution and the British Popular Novel” takes as its focus the significant role which historical fiction played within the French Revolution debate and its aftermath. Examining the complex intersection of the genre with the political and historical dialogue generated by the French Revolution crisis, the thesis contends that contemporary fascination with the historical episode of the Revolution, and the fundamental importance of history to the disputes which raged about questions of tradition and change, and the meaning of the British national past, led to the emergence of increasingly complex forms of fictional historical narrative during the “war of ideas.” Considering the varying ways in which novelists such as Charlotte Smith, William Godwin, Mary Robinson, Helen Craik, Clara Reeve, John Moore, Edward Sayer, Mary Charlton, Ann Thomas, George Walker and Jane West engaged with the historical contexts of the Revolution debate, my discussion juxtaposes the manner in which English Jacobin novelists inserted the radical critique of the Jacobin novel into the wider arena of history with anti-Jacobin deployments of the historical to combat the revolutionary threat and internal moves for socio-political restructuring. I argue that the use of imaginative historical narrative to contribute to the ongoing dialogue surrounding the Revolution, and offer political and historical guidance to readers, represented a significant element within the literature of the Revolution crisis. The thesis also identifies the diverse body of historical fiction which materialised amidst the Revolution controversy as a key context within which to understand the emergence of Scott’s national historical novel in 1814, and the broader field of historical fiction in the era of Waterloo. Tracing the continued engagement with revolutionary and political concerns evident in the early Waverley novels, Frances Burney’s The Wanderer (1814), William Godwin’s Mandeville (1816), and Mary Shelley’s Valperga (1823), my discussion concludes by arguing that Godwin’s and Shelley’s extension of the mode of historical fiction initially envisioned by Godwin in the revolutionary decade, and their shared endeavour to retrieve the possibility enshrined within the republican past, appeared as a significant counter to the model of history and fiction developed by Walter Scott in the post-revolutionary epoch.

The Ontogeny of Mucosal and Systemic Antibody Responses to HIV-1 Infection

The humoral immune system plays a critical role in the clearance of numerous pathogens. In the setting of HIV-1 infection, the virus infects, integrates its genome into the host's cells, replicates, and establishes a reservoir of virus-infected cells. The initial antibody response to HIV-1 infection is targeted to non-neutralizing epitopes on HIV-1 Env gp41, and when a neutralizing response does develop months after transmission, it is specific for the autologous founder virus and the virus escapes rapidly. After continuous waves of antibody mediated neutralization and viral escape, a small subset of infected individuals eventually develop broad and potent heterologous neutralizing antibodies years after infection. In this dissertation, I have studied the ontogeny of mucosal and systemic antibody responses to HIV-1 infection by means of three distinct aims: 1. Determine the origin of the initial antibody response to HIV-1 infection. 2. Characterize the role of restricted VH and VL gene segment usage in shaping the antibody response to HIV-1 infection. 3. Determine the role of persistence of B cell clonal lineages in shaping the mutation frequencies of HIV-1 reactive antibodies.

After the introduction (Chapter 1) and methods (Chapter 2), Chapter 3 of this dissertation describes a study of the antibody response of terminal ileum B cells to HIV-1 envelope (Env) in early and chronic HIV-1 infection and provides evidence for the role of environmental antigens in shaping the repertoire of B cells that respond to HIV-1 infection. Previous work by Liao et al. demonstrated that the initial plasma cell response in the blood to acute HIV-1 infection is to gp41 and is derived from a polyreactive memory B cell pool. Many of these antibodies cross-reacted with commensal bacteria, Therefore, in Chapter 3, the relationship of intestinal B cell reactivity with commensal bacteria to HIV-1 infection-induced antibody response was probed using single B cell sorting, reverse transcription and nested polymerase chain reaction (RT- PCR) methods, and recombinant antibody technology. The dominant B cell response in the terminal ileum was to HIV-1 envelope (Env) gp41, and 82% of gp41- reactive antibodies cross-reacted with commensal bacteria whole cell lysates. Pyrosequencing of blood B cells revealed HIV-1 antibody clonal lineages shared between ileum and blood. Mutated IgG antibodies cross-reactive with both Env gp41 and commensal bacteria could also be isolated from the terminal ileum of HIV-1 uninfected individuals. Thus, the antibody response to HIV-1 can be shaped by intestinal B cells stimulated by commensal bacteria prior to HIV-1 infection to develop a pre-infection pool of memory B cells cross-reactive with HIV-1 gp41.

Chapter 4 details the study of restricted VH and VL gene segment usage for gp41 and gp120 antibody induction following acute HIV-1 infection; mutations in gp41 lead to virus enhanced neutralization sensitivity. The B cell repertoire of antibodies induced in a HIV-1 infected African individual, CAP206, who developed broadly neutralizing antibodies (bnAbs) directed to the HIV-1 envelope gp41 membrane proximal external region (MPER), is characterized. Understanding the selection of virus mutants by neutralizing antibodies is critical to understanding the role of antibodies in control of HIV-1 replication and prevention from HIV-1 infection. Previously, an MPER neutralizing antibody, CAP206-CH12, with the binding footprint identical to that of MPER broadly neutralizing antibody 4E10, that like 4E10 utilized the VH1-69 and VK3-20 variable gene segments was isolated from this individual (Morris et al., 2011). Using single B cell sorting, RT- PCR methods, and recombinant antibody technology, Chapter 4 describes the isolation of a VH1-69, Vk3-20 glycan-dependent clonal lineage from CAP206, targeted to gp120, that has the property of neutralizing a neutralization sensitive CAP206 transmitted/founder (T/F) and heterologous viruses with mutations at amino acids 680 or 681 in the MPER 4E10/CH12 binding site. These data demonstrate sites within the MPER bnAb epitope (aa 680-681) in which mutations can be selected that lead to viruses with enhanced sensitivity to autologous and heterologous neutralizing antibodies.

In Chapter 5, I have completed a comparison of evolution of B cell clonal lineages in two HIV-1 infected individuals who have a predominant VH1-69 response to HIV-1 infection--one who produces broadly neutralizing MPER-reactive mAbs and one who does not. Autologous neutralization in the plasma takes ~12 weeks to develop (Gray et al., 2007; Tomaras et al., 2008b). Only a small subset of HIV-1 infected individuals develops high plasma levels of broad and potent heterologous neutralization, and when it does occur, it typically takes 3-4 years to develop (Euler et al., 2010; Gray et al., 2007; 2011; Tomaras et al., 2011). The HIV-1 bnAbs that have been isolated to date have a number of unusual characteristics including, autoreactivity and high levels of somatic hypermutations, which are typically tightly regulated by immune control mechanisms (Haynes et al., 2005; 2012b; Kwong and Mascola, 2012; Scheid et al., 2009a). The VH mutation frequencies of bnAbs average ~15% but have been shown to be as high as 32% (reviewed in Mascola and Haynes, 2013; Kwong and Mascola, 2012). The high frequency of somatic hypermutations suggests that the B cell clonal lineages that eventually produce bnAbs undergo high-levels of affinity maturation, implying prolonged germinal center (GC) reactions and high levels of T cell help. To study the duration of HIV-1- reactive B cell clonal persistence, HIV-1 reactive and non HIV-1- reactive B cell clonal lineages were isolated from an HIV-1 infected individual that produces bnAbs, CAP206, and an HIV-1 infected individual who does not produce bnAbs, 004-0. Single B cell sorting, RT-PCR and recombinant antibody technology was used to isolate and produce monoclonal antibodies from multiple time points from each individual. B cell sequences clonally related to mAbs isolated by single cell PCR were identified within pyrosequences of longitudinal samples of these two individuals. Both individuals produced long-lived B cell clones that persisted from 0-232 weeks in CAP206, and 0-238 weeks in 004-0. The average length of persistence of clones containing members isolated from two separate time points was 91.5 weeks both individuals. Examples of the continued evolution of clonal lineages were observed in both the bnAb and non-bnAb individual. These data indicated that the ability to generate persistent and evolving B cell clonal lineages occurs in both bnAb and non-bnAb individuals, suggesting that some alternative host or viral factor is critical for the generation of highly mutated broadly neutralizing antibodies.

Together the studies described in Chapter 3-5 show that multiple factors influence the antibody response to HIV-1 infection. The initial antibody response to HIV-1 Env gp41 can be shaped by a B cell response to intestinal commensal bacteria prior to HIV-1 infection. VH and VL gene segment restriction can impact the B cell response to multiple HIV-1 antigens, and virus escape mutations in the MPER can confer enhanced neutralization sensitivity to autologous and heterologous antibodies. Finally, the ability to generate long-lived HIV-1 clonal lineages in and of itself does not confer on the host the ability to produce bnAbs.

Efficacy of Pharmacokinetics-Directed Busulfan, Cyclophosphamide, and Etoposide Conditioning and Autologous Stem Cell Transplantation for Lymphoma: Comparison of a Multicenter Phase II Study and CIBMTR Outcomes.

Busulfan, cyclophosphamide, and etoposide (BuCyE) is a commonly used conditioning regimen for autologous stem cell transplantation (ASCT). This multicenter, phase II study examined the safety and efficacy of BuCyE with individually adjusted busulfan based on preconditioning pharmacokinetics. The study initially enrolled Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) patients ages 18 to 80 years but was amended due to high early treatment-related mortality (TRM) in patients > 65 years. BuCyE outcomes were compared with contemporaneous recipients of carmustine, etoposide, cytarabine, and melphalan (BEAM) from the Center for International Blood and Marrow Transplant Research. Two hundred seven subjects with HL (n = 66) or NHL (n = 141) were enrolled from 32 centers in North America, and 203 underwent ASCT. Day 100 TRM for all subjects (n = 203), patients > 65 years (n = 17), and patients ≤ 65 years (n = 186) were 4.5%, 23.5%, and 2.7%, respectively. The estimated rates of 2-year progression-free survival (PFS) were 33% for HL and 58%, 77%, and 43% for diffuse large B cell lymphoma (DLBCL; n = 63), mantle cell lymphoma (MCL; n = 29), and follicular lymphoma (FL; n = 23), respectively. The estimated rates of 2-year overall survival (OS) were 76% for HL and 65%, 89%, and 89% for DLBCL, MCL, and FL, respectively. In the matched analysis rates of 2-year TRM were 3.3% for BuCyE and 3.9% for BEAM, and there were no differences in outcomes for NHL. Patients with HL had lower rates of 2-year PFS with BuCyE, 33% (95% CI, 21% to 46%), than with BEAM, 59% (95% CI, 52% to 66%), with no differences in TRM or OS. BuCyE provided adequate disease control and safety in B cell NHL patients ≤ 65 years but produced worse PFS in HL patients when compared with BEAM.

Innovations in learning and teaching approaches using game technologies - can "The Movies" teach how to make a movie?

The use of games technology in education is not a new phenomenon. Even back in the days of 286 processors, PCs were used in some schools along with (what looks like now) primitive simulation software to teach a range of different skills and techniques – from basic programming using Logo (the turtle style car with a pen at the back that could be used to draw on the floor – always a good way of attracting the attention of school kids!) up to quite sophisticated replications of physical problems, such as working out the trajectory of a missile to blow up an enemies’ tank. So why are games not more widely used in education (especially in FE and HE)? Can they help to support learners even at this advanced stage in their education? We aim to provide in this article an overview of the use of game technologies in education (almost as a small literature review for interested parties) and then go more in depth into one particular example we aim to introduce from this coming academic year (Sept. 2006) to help with teaching and assessment of one area of our Multimedia curriculum. Of course, we will not be able to fully provide the reader with data on how successful this is but we will be running a blog (http://themoviesineducation.blogspot.com/) to keep interested parties up to date with the progress of the project and to hopefully help others to set up similar solutions themselves. We will also only consider a small element of the implementation here and cover how the use of such assessment processes could be used in a broader context. The use of a game to aid learning and improve achievement is suggested because traditional methods of engagement are currently failing on some levels. By this it is meant that various parts of the production process we normally cover in our Multimedia degree are becoming difficult to monitor and continually assess.

The UK WTC 9/11 evacuation study: an overview of the methodologies employed and some analysis relating to fatigue, stair travel speeds and occupant response times

This paper briefly describes the methodologies employed in the collection and storage of first-hand accounts of evacuation experiences derived from face-to-face interviews with evacuees from the World Trade Center (WTC) Twin Towers complex on 11 September 2001 and the development of the High-rise Evacuation Evaluation Database (HEED). The main focus of the paper is to present an overview of preliminary analysis of data derived from the evacuation of the North Tower.

Melancholy and the Early Modern University

Critics have observed that in early Stuart England, the broad, socially significant concept of melancholy was recoded as a specifically medical phenomenon—a disease rather than a fashion. This recoding made melancholy seem less a social attitude than a private ailment. However, I argue that at the Stuart universities, this recoded melancholy became a covert expression of the disillusionment, disappointment, and frustration produced by pressures there—the overcrowding and competition which left many men “disappointed” in preferment, alongside James I’s unprecedented royal involvement in the universities. My argument has implications for Jürgen Habermas’s account of the emergence of the public sphere, which he claims did not occur until the eighteenth-century. I argue that although the university was increasingly subordinated to the crown’s authority, a lingering sense of autonomy persisted there, a residue of the medieval university’s relative autonomy from the crown; politicized by the encroaching Stuart presence, an alienated community at the university formed a kind of public in private from authority within that authority’s midst. The audience for the printed book, a sphere apart from court or university, represented a forum in which the publicity at the universities could be consolidated, especially in seemingly “private” literary forms such as the treatise on melancholy. I argue that Robert Burton’s exaggerated performance of melancholy in The Anatomy of Melancholy, which gains him license to say almost anything, resembles the performed melancholy that the student-prince Hamlet uses to frustrate his uncle’s attempts to surveil him. After tracing melancholy’s evolving literary function through Hamlet, I go on to discuss James’s interventions into the universities. I conclude by considering two printed (and widely circulated) books by university men: the aforementioned The Anatomy of Melancholy by Burton, an Oxford cleric, and The Temple by George Herbert, who left a career as Cambridge’s public orator to become a country parson. I examine how each of these books uses the affective pattern of courtly-scholarly disappointment—transumed by Burton as melancholy, and by Herbert as holy affliction—to develop an empathic form of publicity among its readership which is in tacit opposition to the Stuart court.

The Holocene British and Irish ancient woodland fossil beetle fauna: implications for forest history, biodiversity and faunal colonisation

This paper presents a new review of our knowledge of the ancient forest beetle fauna from Holocene archaeological and palaeoecological sites in Great Britain and Ireland. It examines the colonisation, dispersal and decline of beetle species, highlighting the scale and nature of human activities in the shaping of the landscape of the British Isles. In particular, the paper discusses effects upon the insect fauna, and examines in detail the fossil record from the Humberhead Levels, eastern England. It discusses the local extirpation of up to 40 species in Britain and 15 species in Ireland. An evaluation of the timing of extirpations is made, suggesting that many species in Britain disappear from the fossil record between c. 3000 cal BC and 1000 cal BC (c. 5000-3000 cal BP), although some taxa may well have survived until considerably later. In Ireland, there are two distinct trends, with a group of species which seem to be absent after c. 2000 cal BC (c. 4000 cal BP) and a further group which survives until at least as late as the medieval period. The final clearance of the Irish landscape over the last few hundred years was so dramatic, however, that some species which are not especially unusual in a British context were decimated. Reasons behind the extirpation of taxa are examined in detail, and include a combination of forest clearance and human activities, isolation of populations, lack of temporal continuity of habitats, edaphic and competition factors affecting distribution of host trees (particularly pine), lack of forest fires and a decline in open forest systems. The role of climate change in extirpations is also evaluated. Consideration is given to the significance of these specialised ancient forest inhabitants in Ireland in the absence of an early Holocene land-bridge which suggests that colonisation was aided by other mechanisms, such as human activities and wood-rafting. Finally, the paper discusses the Continental origins of the British and Irish fauna and its hosts and the role played by European glacial refugia.
