description: Conventional techniques for laser cooling, by coherent scattering off of internal states or through an optical cavity mode, have so far proved inefficient on mechanical oscillators heavier than a few nanograms. That is because larger oscillators vibrate at frequencies much too small compared to the scattering rates achievable by their coupling to auxiliary modes. Decoherence mechanisms typically observed in heavy low frequency elastically suspended oscillators also differ markedly from what is assumed in conventional treatments of laser cooling. We show that for a low-frequency anelastic oscillator forming the mechanically compliant end-mirror of a cavity, detuned optical readout, together with measurement-based feedback to stiffen and dampen it, can harness ponderomotively generated quantum correlations, to realize efficient cooling to the motional ground state. This will pave the way for experiments that call for milligram-scale mechanical oscillators prepared in pure motional states, for example, for tests of gravity's effect on massive quantum systems.

Short-Cut nitrogen removal and PHA Recovery technology

description: Abstract: This work focusses on extending the ASM3 model towards the description of short-cut
 nitrogen removal and simultaneous polyhydroxyalkanoate (PHA) recovery and the subsequent model
 application to describe this process currently operated at the pilot-scale in Carbonera, Italy. Results
 indicated that the calibrated and validated model could describe well the nitritation process, coupled
 with the aerobic feast/anoxic famine process for the selection of PHA producing organisms. The model
 will also be applied to test alternative operational strategies designed to maximise PHA recovery.

description: Observing in six frequency bands from 27 to 280 GHz over a large sky area, the Simons Observatory (SO) is poised to address many questions in Galactic astrophysics in addition to its principal cosmological goals. In this work, we provide quantitative forecasts on astrophysical parameters of interest for a range of Galactic science cases. We find that SO can: constrain the frequency spectrum of polarized dust emission at a level of $Δβ_d \lesssim 0.01$ and thus test models of dust composition that predict that $β_d$ in polarization differs from that measured in total intensity; measure the correlation coefficient between polarized dust and synchrotron emission with a factor of two greater precision than current constraints; exclude the non-existence of exo-Oort clouds at roughly 2.9$σ$ if the true fraction is similar to the detection rate of giant planets; map more than 850 molecular clouds with at least 50 independent polarization measurements at 1 pc resolution; detect or place upper limits on the polarization fractions of CO(2-1) emission and anomalous microwave emission at the 0.1% level in select regions; and measure the correlation coefficient between optical starlight polarization and microwave polarized dust emission in $1^\circ$ patches for all lines of sight with $N_{\rm H} \gtrsim 2\times10^{20}$ cm$^{-2}$. The goals and forecasts outlined here provide a roadmap for other microwave polarization experiments to expand their scientific scope via Milky Way astrophysics.

description: Background: Following stroke, many people have difficulty activating their paretic muscles quickly and with sufficient power to regain their balance by taking quick and effective steps. Reduced dynamic balance and mobility following stroke, or ‘walking balance’, is associated with reduced self-efficacy and restrictions in daily living activities, community integration, and quality of life. Targeted training of movement speeds required to effectively regain balance has been largely overlooked in post-stroke rehabilitation. The Fast muscle Activation and Stepping Training (FAST) program incorporates fast functional movements known to produce bursts of muscle activation essential for stepping and regaining standing balance effectively. The purpose of this study is to: 1) compare the effectiveness of an outpatient FAST program to an active control outpatient physiotherapy intervention in improving walking balance following stroke, and 2) explore potential mechanisms associated with improvements in walking balance. Methods/Design: This will be an assessor-blinded, parallel group randomized controlled trial design. Sixty participants (30 per group) who have sustained a stroke within the previous six months will be randomly assigned with stratification for lower limb motor recovery to receive twelve 45-minute 1:1 physiotherapy intervention sessions over 6 – 10 weeks in an outpatient setting of either: 1) FAST intervention - systematic and progressive practice of fast squatting and stepping exercises, or 2) active control - conventional physiotherapy directed at improving balance and mobility that includes no targeted fast movement training. The same blinded research physiotherapist will assess outcomes at three time points: 1) baseline (prior to intervention), 2) follow up (within one week post-intervention); and 3) retention (one month post-intervention). The primary outcome is dynamic balance assessed using the Community Balance and Mobility Scale. We will also assess fast and self-selected walking speed, balance self-efficacy, and the ability to respond to internal and external perturbations to balance and associated changes in postural muscle activation. Discussion: The targeted training of fast functional movements in the FAST program is expected to improve walking balance following stroke compared to the active control intervention. Unique to this study is the investigation of potential mechanisms associated with improvements in walking balance. Trial registration: NCT01573585

description: The construction of the potential energy surface (PES) of even a medium-sized molecule employing correlated theory, such as CCSD(T), is an arduous task due to the high computational cost. In this Letter, we report the possibility of efficient construction of such a PES employing the molecular tailoring approach (MTA) on off-the-shelf hardware. The full calculation (FC) as well as MTA energies at CCSD(T)/aug-cc-pVTZ level for three test molecules, viz. acetylacetone, N-methyacetamide, and tropolone are reported. All the MTA energies are in excellent agreement with their FC counterparts (typical error being sub-millihartree) with a time advantage factor of 3 to 5. The energy barrier from the ground- to transition-state is accurately captured. Further, the accuracy and efficiency of the MTA method for estimating energy gradients at CCSD(T) level are demonstrated. This work brings out the possibility of the construction of PES for large molecules using MTA with the computational economy at a high level of theory and/or basis set.
Population Abundance and Habitat Requirements of the Marsh Wren (Cistothorus palustris) at Dyke Marsh Wildlife Preserve: An Urban Conservation Challenge

description: In 1998 and 1999, I estimated the abundance of a population of marsh wrens ( Cistothorus palustris) at Dyke Marsh National Wildlife Preserve based on number of territories. In addition, I estimated the reproductive success based on number of fledglings. For 1999 only, the percent of available habitat used; male and female habitat selection preferences; the variation in territory quality between successful and failed nests; causes of nest failure; and use of alternative vegetation for nest sites were investigated. In 1999, I also surveyed other marshes in the upper tidal zone of the Potomac to verify whether Dyke Marsh contains the only population of marsh wrens in this area. The differences between territories and non-territories for male selection preferences based on seven habitat variables. Nine habitat variables were used to measure differences between breeding and non-breeding territories and between successful and failed nests. Differences between groups were analyzed using non-parametric tests. Reproductive success was based upon actual number of fledglings. Thirty-one territories were located in 1998, and 34 in 1999. The population estimate was 38 (31 territorial males and 7 breeding females) in 1998, and 48 (34 territorial males and 14 breeding females) in 1999. This number excludes roving bachelors, and second or third mates of polygynous males. The discrepancy in the female number between years may reflect insufficient manpower to discover all breeding nests in 1998. Reproductive success for 1998 was nine young fledged; for 1999, eleven young fledged. Only 30% percent of available habitat was used by marsh wrens in 1999. Absolute density of tall, emergent vegetation (P = 0.003 ) and proximity to red-winged blackbirds (P = 0.011) were the most significant habitat variables driving male selection preferences. Percent Typha spp. was a marginally sigificant factor (P = 0.089) for female selection. No significant difference was detected between successful (n=S} and failed (n=11) nests in 1999 for any of the variables measured. The majority (79%) of nest failure is due to predation by conspecifics, or interspecific birds, snakes, small mammals. Only four territories used non-cattail vegetation for nest attachment but none of the nests attached to alternative species became breeding nests. A survey of similar tidal marshes in the upper Potomac tidal zone revealed that there are no other breeding populations of marsh wrens in this area. Because the local population of marsh wrens has very narrow preferences for nesting territories, has experienced substantial habitat loss over the last few decades, are subject to high rates of predation, and do not appear to be very adaptable to alternative forms of vegetation, the population could be at risk over the long term.

description: Coverage-guided fuzz testing ("fuzzing") has become mainstream and we have observed lots of progress in this research area recently. However, it is still challenging to efficiently test network services with existing coverage-guided fuzzing methods. In this paper, we introduce the design and implementation of Nyx-Net, a novel snapshot-based fuzzing approach that can successfully fuzz a wide range of targets spanning servers, clients, games, and even Firefox's Inter-Process Communication (IPC) interface. Compared to state-of-the-art methods, Nyx-Net improves test throughput by up to 300x and coverage found by up to 70%. Additionally, Nyx-Net is able to find crashes in two of ProFuzzBench's targets that no other fuzzer found previously. When using Nyx-Net to play the game Super Mario, Nyx-Net shows speedups of 10-30x compared to existing work. Under some circumstances, Nyx-Net is even able play "faster than light": solving the level takes less wall-clock time than playing the level perfectly even once. Nyx-Net is able to find previously unknown bugs in servers such as Lighttpd, clients such as MySQL client, and even Firefox's IPC mechanism - demonstrating the strength and versatility of the proposed approach. Lastly, our prototype implementation was awarded a $20.000 bug bounty for enabling fuzzing on previously unfuzzable code in Firefox and solving a long-standing problem at Mozilla.

description: Chest X-ray (CXR) is a widely performed radiology examination that helps to detect abnormalities in the tissues and organs in the thoracic cavity. Detecting pulmonary abnormalities like COVID-19 may become difficult due to that they are obscured by the presence of bony structures like the ribs and the clavicles, thereby resulting in screening/diagnostic misinterpretations. Automated bone suppression methods would help suppress these bony structures and increase soft tissue visibility. In this study, we propose to build an ensemble of convolutional neural network models to suppress bones in frontal CXRs, improve classification performance, and reduce interpretation errors related to COVID-19 detection. The ensemble is constructed by (i) measuring the multi-scale structural similarity index (MS-SSIM) score between the sub-blocks of the bone-suppressed image predicted by each of the top-3 performing bone-suppression models and the corresponding sub-blocks of its respective ground truth soft-tissue image, and (ii) performing a majority voting of the MS-SSIM score computed in each sub-block to identify the sub-block with the maximum MS-SSIM score and use it in constructing the final bone-suppressed image. We empirically determine the sub-block size that delivers superior bone suppression performance. It is observed that the bone suppression model ensemble outperformed the individual models in terms of MS-SSIM and other metrics. A CXR modality-specific classification model is retrained and evaluated on the non-bone-suppressed and bone-suppressed images to classify them as showing normal lungs or other COVID-19-like manifestations. We observed that the bone-suppressed model training significantly outperformed the model trained on non-bone-suppressed images toward detecting COVID-19 manifestations.

description: Background: Waist circumference, a metabolic syndrome (MetSy) criterion, is not routinely measured in clinical practice making early identification of individuals with MetSy challenging. It has been argued that ratios of commonly measured parameters such as lipids and lipoproteins may be an acceptable alternative for identifying individuals with MetSy. The objective of our study was to explore clinical utility of lipid ratios to identify men and women with MetSy; and to explore the association between lipid ratios and the number of MetSy components. Methods Men and women (N = 797) of Aboriginal, Chinese, European, and South Asian origin (35–60 years), recruited across ranges of body mass index (BMI), with no diagnosed cardiovascular disease (CVD) or on medications to treat CVD risk factors were assessed for anthropometrics, family history of CVD, MetSy components (waist circumference, blood pressure, glucose, triglycerides (TG), high-density-lipoprotein-cholesterol (HDL-C)), low-density-lipoprotein-cholesterol (LDL-C), nonHDL-C, and health-related behaviours. Results Mean levels of lipid ratios significantly increased with increasing number of MetSy components in men and women (p < 0.05). After adjustment for age, ethnicity, smoking, alcohol consumption, physical activity, family history of CVD and BMI, (and menopausal status in women), all lipid ratios were associated with the number of MetSy components in men and women (Poisson regression, p < 0.001). Compared to the rest of the lipid ratios (ROC curve analysis), TG/HDL-C was best able to discriminate between individuals with and without MetSy (AUC = 0.869 (95% CI: 0.830, 0.908) men; AUC = 0.872 (95% CI: 0.832, 0.912) women). The discriminatory power of TC/HDL-C and nonHDL-C/HDL-C to identify individuals with MetSY was the same (for both ratios, AUC = 0.793 (95% CI: 0.744, 0.842) men; 0.818 (95% CI: 0.772, 0.864) women). Additionally, LDL-C/HDL-C was a good marker for women (AUC = 0.759 (95% CI: 0.706, 0.812)), but not for men (AUC = 0.689 (95% CI: 0.631, 0.748)). Based on a multiethnic sample, we identified TG/HDL-C cut-off values of 1.62 in men and 1.18 in women that were best able to discriminate between men and women with and without MetSY. Conclusions Our results indicate that TG/HDL-C is a superior marker to identify men and women with MetSy compared to TC/HDL-C, LDL-C/HDL-C, and nonHDL-C/HDL-C.

Creators: name: Tupou, Trish

description: This thesis explores the establishment of Tongan sovereignty through a Tongan feminist lens. By examining the 19th century politics of Tonga, I consider how changes to religion, the introduction of written legal codes, and the eventual promulgation of the Tongan Constitution had violent consequences for women. This period in Tonga's past foreclosed the erotic freedom and agency of women which continues to ripple through the diaspora and Tonga's on-the-ground politics today. My thesis works to recenter and unearth the Tongan divine feminine in unsettling mainstream projections of Tonga as the 'true South Pacific' and the 'last remaining kingdom.' I examine our Tongan historical canon and recast the stories of women who were misrepresented as mere appendages to independence: as a murdered priestess, or as a strategic pawn used through marriage, or as only being in relationship with the fonua (land) through the formalization of land tenure via one's husband. I consider the queer possibilities of our past as captured through the stories of deities and women. Utilizing Tongan concepts and practices of fonua (land, nation, placenta, people), fananga (storytelling), and manatu (memory) I rethink gendered connections to land, as well as renegotiate the ta va (time and space) of our Tongan diaspora communities that influence our sovereignty. My research is guided by the central question: what is Tongan queer joy? From this, I question how we might build different forms of Indigenous sovereignty whilst establishing the power of an embodied archive that challenges the erasures of colonial legacies and the mapping of this violence onto our ontologies of land, gender, and sexualities..

description: In Australian Higher Education there is much discussion about developing curriculum that will prepare a diverse student group for a changing world. Thus it is important to create a learning environment where generic skills essential for the workforce are developed along with specific technical knowledge. To this end a learning space was created where students were involved in a negotiated learning experience. This took the form of a student-run academic conference which was organised as part of a Quality Management subject within a Business degree. In this context the students were simultaneously dealing with quality management theory and putting it into practice. There were several interconnected themes which included generic skills, contextualised and interdisciplinary learning.

description: Human transformation of the terrestrial biosphere via resource utilization is a critical impetus for monitoring and characterizing anthropogenic change to vegetation condition. The primary objective of this research was to detect anthropogenic forest disturbance for a recent Landsat time series. A novel combination of an autonomous change detection procedure and spectral classification scheme was applied and tested in a landscape that has undergone significant resource development over the last 30 years. Anthropogenic disturbance was detected with greater than 93% accuracy. Most disturbances were correctly classified to within ±1 year. The signal of anthropogenic disturbance was significant in the landscape, accounting for more than 91% of all disturbances and 86% of total disturbed area during the 23-year study period. The study demonstrated a robust approach for examining historical disturbance trends related to human-modification of the environment.

description: The iron-based superconductors (IBSs) of the recently discovered 1144 class, unlike many other IBSs, display superconductivity in their stoichiometric form and are intrinsically hole doped. The effects of chemical substitutions with electron donors are thus particularly interesting to investigate. Here, we study the effect of Co substitution in the Fe site of CaKFe$_4$As$_4$ single crystals on the critical temperature, on the energy gaps, and on the superfluid density by using transport, point-contact Andreev-reflection spectroscopy (PCARS), and London penetration depth measurements. The pristine compound (T$_\mathrm{c}\simeq$ 36 K) shows two isotropic gaps whose amplitudes ($Δ_1$ = 1.4$-$3.9 meV and $Δ_2$ = 5.2$-$8.5 meV) are perfectly compatible with those reported in the literature. Upon Co doping (up to $\approx$7% Co), T$_\mathrm{c}$ decreases down to $\simeq$ 20 K, the spin-vortex-crystal order appears, and the low-temperature superfluid density is gradually suppressed. PCARS and London penetration depth measurements perfectly agree in demonstrating that the nodeless multigap structure is robust upon Co doping, while the gap amplitudes decrease as a function of T$_\mathrm{c}$ in a linear way with almost constant values of the gap ratios 2$Δ_i$/k$_\mathrm{B}$T$_\mathrm{c}$.

Creators: name: Lee, David John
Publisher: name: Goldsmiths, University of London

description: Broadcasting is undergoing a period of profound change. Convergence and digitisation are reshaping production and consumption. In the multi-channel environment, public service broadcasting (PSB) finds itself under threat, as traditional funding models are threatened by increased choice, new modes of delivery, and, for commercial public service broadcasters, a reduction in advertising revenue. In the UK, the industry base has undergone significant restructuring over the last twenty-five years. This has occurred following the creation of Channel 4 in 1982, and the emergence of the independent television production sector (ITPS) , coupled with a steady process of employment and industry deregulation. Labour in the sector is now predominantly freelance (Skillset, 2006a, 2007a), and increasingly concentrated in the ITPS, largely in London but with growing production bases at a regional level. Furthermore, the independent sector itself is reshaping, from a sector predominantly made up of small 'one-man band' lifestyle companies, to the more commercially facing, vertically integrated 'super-indies' which now dominate the sector (Mediatique, 2004). In this context of transformation, this thesis is an investigation of creative labour in the ITPS in the UK, focused specifically on factual television production. Based on extended qualitative research of a group of twenty individuals over a six-month period, and supplementary interviews with company managers, the research examines the nature of work and production for individuals in this industry. The sample is cross-generational and includes a wide range of production positions, from researcher to series producer. The research focuses on the consequences of casualisation and risk for television workers, exploring how they manage their careers in the face of rampant insecurity. Drawing on Sennett's (1998) method of narrative sociology, the thesis explores the personal consequences of flexible labour markets (of which television is exemplary) on working individuals. It focuses on the subjective response of individuals to working in this area of the cultural economy, exploring the attractions of cultural labour despite the ontological insecurity and (self)-exploitation which often accompanies such work. It examines the emergence of 'network sociality' (Wittel, 2001) in the creative labour market, and the implications of this for recruitment and access to the television industry. Finally, it utilises the notion of 'craft' (Sennett, 2006), in order to explore the impact of flexible accumulation on television workers' production values

description: Dr. Charles Pickering (1805-1878) departed the Americas in 1838 a naturalist but returned a race scientist. His years abroad on the United States South Seas Exploring Expedition (1838-1842) were transformative: his voyage through Oceania was characterised by a rapid but ultimately uneven shift in his thinking about the nature of human difference and humanity's relationship to the environment. His primary contribution to the Expedition's lengthy list of publications, titled The Races of Man and their Geographical Distribution, was described by one contemporary as "unstratified as a dumpling and heterogeneous as a low-priced sausage" and the incoherence of this work has vexed readers since. After his return from the Pacific, in the face of mixed responses, he became a fixture on the stage of mid-nineteenth century Atlantic science, influencing thinkers like Charles Darwin and facilitating the growth of scientific societies and disciplines in the United States. Despite this, his life and work has largely been passed over in favour of studies of his more assertive and less inconsistent colleagues. This study illustrates the ways that Pickering's travels and interactions aboard the Expedition led to his ultimately incoherent inventions of race, showing the contradictory ways that race thinking propelled and subverted his sometimes-brilliant scientific work. This is a history of thinking, rather than thought - a survey of Pickering's situated, transitory and contingent moments of clarity - and it shows both the utility and complications of race science for one of those who worked to bring it to the public. In recent years the US Exploring Expedition has been the topic of a growing body of research, and this thesis adds a novel perspective to those histories while also contributing to broader studies of antebellum science, histories of race, and its encounters with self, objects, and others in the Pacific.
title: Women in the Imperial Art World: Anglo-Australian Women Artists and their Transnational Careers, 1885 - 1907
Creators: name: Nicholls, Lara
Publisher: name: The Australian National University

description: Upon receiving a folio of drawings from the Anglo-Australian artist Sophia Sinnett in 1875, the British art critic John Ruskin replied to her with the advice, 'you must resolve to be quite a great paintress; the feminine termination does not exist, there never having been such a being...as a lady who could paint. Try to be the first'. Almost a century later in Australia, the art historian Bernard Smith opined in his foundational text, 'Australian Painting 1788-1960', 'But women, perhaps because of their status in Victorian and Edwardian society and other reasons that need not be discussed here, did not figure prominently in Australian art prior to the First World War.' Were there so few 'great' women artists in Britain in the late nineteenth century as Ruskin supposed? Were women artists invisible in Australian colonial society, as concluded by Bernard Smith? This thesis is concerned with these questions because the preconception that both British and Australian professional women artists were absent in the imperial art world clouds many accounts of nineteenth-century art history. Furthermore, ideas of 'greatness' and 'invisibility' are foundational concepts in key feminist texts which revise such assumptions. Through careful examination of both quantitative data from exhibition and museum catalogues and contextual evidence from the period, I argue that British-Australian women artists in the late nineteenth century were more visible in the imperial art world than has hitherto been recognised in accounts of British or Australian art. The lives and works of the Anglo-Australian women artists discussed in this thesis do not correspond to the notion expressed by Ruskin that the nineteenth-century woman artist was merely a 'lady who could paint'. Nor do they correspond to Smith's description of a late nineteenth-century art world devoid of women artists. Rather, the research in this thesis reveals that women in the period created considerable works of art and competed in the same imperial art world arenas as their male counterparts. Indeed, as women of empire, they were influential global art citizens.

description: Background: Increasing multidrug resistance in gram-negative bacilli (GNB) infections poses a serious threat to public health. Few studies have analyzed co-resistance rates, defined as an antimicrobial susceptibility profile in a subset already resistant to one specific antibiotic. The epidemiologic and clinical utility of determining co-resistance rates are analyzed and discussed. Methods A 10-year retrospective study from 2002–2011 of bloodstream infections with GNB were analyzed from three hospitals in Greater Vancouver, BC, Canada. Descriptive statistics were calculated for antimicrobial resistance and co-resistance. Statistical analysis further described temporal trends of antimicrobial resistance, correlations of resistance between combinations of antimicrobials, and temporal trends in co-resistance patterns. Results The total number of unique blood stream isolates of GNB was 3280. Increasing resistance to individual antimicrobials was observed for E. coli, K. pneumoniae, K. oxytoca, E. cloacae, and P. aeruginosa. Ciprofloxacin resistance in E. coli peaked in 2006 at 40% and subsequently stabilized at 29% in 2011, corresponding to decreasing ciprofloxacin usage after 2007, as assessed by defined daily dose utilization data. High co-resistance rates were observed for ceftriaxone-resistant E. coli with ciprofloxacin (73%), ceftriaxone-resistant K. pneumoniae with trimethoprim-sulfamethoxazole (83%), ciprofloxacin-resistant E. cloacae with ticarcillin-clavulanate (91%), and piperacillin-tazobactam-resistant P. aeruginosa with ceftazidime (83%). Conclusions Increasing antimicrobial resistance was demonstrated over the study period, which may partially be associated with antimicrobial consumption. The study of co-resistance rates in multidrug resistant GNB provides insight into the epidemiology of resistance acquisition, and may be used as a clinical tool to aid prescribing empiric antimicrobial therapy.

description: Background Blood neurofilament light chain (NfL) is increasingly considered as a key trial biomarker in genetic frontotemporal dementia (gFTD). We aimed to facilitate the use of NfL in gFTD multicentre trials by testing its (1) reliability across labs; (2) reliability to stratify gFTD disease stages; (3) comparability between blood matrices and (4) stability across recruiting sites. Methods Comparative analysis of blood NfL levels in a large gFTD cohort (GENFI) for (1)–(4), with n=344 samples (n=148 presymptomatic, n=11 converter, n=46 symptomatic subjects, with mutations in C9orf72 , GRN or MAPT ; and n=139 within-family controls), each measured in three different international labs by Simoa HD-1 analyzer. Results NfL revealed an excellent consistency (intraclass correlation coefficient (ICC) 0.964) and high reliability across the three labs (maximal bias (pg/mL) in Bland-Altman analysis: 1.12±1.20). High concordance of NfL across laboratories was moreover reflected by high areas under the curve for discriminating conversion stage against the (non-converting) presymptomatic stage across all three labs. Serum and plasma NfL were largely comparable (ICC 0.967). The robustness of NfL across 13 recruiting sites was demonstrated by a linear mixed effect model. Conclusions Our results underline the suitability of blood NfL in gFTD multicentre trials, including cross-lab reliable stratification of the highly trial-relevant conversion stage, matrix comparability and cross-site robustness. © In Copyright http://rightsstatements.org/vocab/InC/1.0/
A sense of place': the role of the building in the organisation culture of nursing homes

description: This study attempted to identify and explore the role the building plays in the organisation culture of nursing homes. To do this a research plan was formulated in which the central plank was a case-study of a seventy-five bed high care nursing home. As part of the case-study, interviews were conducted at the nursing home with ten members of staff, two residents and a daughter of a resident. The study was also informed by interviews with two architects, who specialise in the design of nursing homes and aged care facilities. A theoretical model entitled the 'Conceptual Framework' was developed prior to the case-study. It was tested by applying it to findings related to the physical context and the organisation culture of the case-study venue. The hypothesis that the building does influence the culture of the nursing home environment was explored by studying the manner in which the building influenced the lives of those who work in the nursing home and those who live there. This challenge was met with the use of theoretical contributions from organisation theory and psychodynamics, which together provided a vehicle for analysis of the culture and the building's role in it.

description: Biofuel plantations have been hyped as a means to reinvigorate Africa’s rural areas. Yet there is still apprehension about the negative environmental and social impacts of large-scale commercial biofuel production around rising food prices, land grabbing, ecological damage, and disruption of rural livelihoods. Given the extent of Jatropha curcas production in Ghana and Ethiopia and Castor bean (Ricinus communis) in Ethiopia, this paper presents the results of a study that assessed the socio-economic implications of industrial Jatropha plantations on local livelihoods in Ghana, and of industrial Jatropha and Castor plantations on local livelihoods in Ethiopia. This study used primary data collected from 234 households in Ghana and 165 in Ethiopia. The cultivation of Jatropha and Castor has had several important effects on local livelihoods in the study sites, most notably decreases in household landholdings due to the arrival of industrial Jatropha or Castor plantations; and the resulting changes these plantations have caused in household socio-economic status, food security, fallow periods, and fodder availability. We consider how a lack of meaningful consultation between local people, their traditional authorities and the biofuel company managers, along with shortcomings in each country’s broader land acquisition process and poor land use information, may have contributed to these overall negative effects on local livelihoods. We conclude by suggesting several ways that emerging biofuel industries could be improved from the perspective of local people and their livelihoods.

description: The interaction between excited states of a molecule and excited states of metal nanostructure (e.g. plasmons) leads to hybrid states with modified optical properties. When plasmon resonance is swept through molecular transition frequency an avoided crossing may be observed, which is often regarded as a signature of strong coupling between plasmons and molecules. Such strong coupling is expected to be realized when $2|U|/{\hbarΓ}>1$, where $U$ and $Γ$ are the molecule-plasmon coupling and the spectral width of the optical transition respectively. Because both $U$ and $Γ$ strongly increase with decreasing distance between a molecule and a plasmonic structure it is not obvious that this condition can be satisfied for any molecule-metal surface distance. In this work we investigate the behavior of $U$ and $Γ$ for several geometries. Surprisingly, we find that if the only contributions to $Γ$ are lifetime broadenings associated with the radiative and nonradiative relaxation of a single molecular vibronic transition, including effects on molecular radiative and nonradiative lifetimes induced by the metal, the criterion $2|U|/{\hbarΓ}>1$ is easily satisfied by many configurations irrespective of the metal-molecule distance. This implies that the Rabi splitting can be observed in such structures if other sources of broadening are suppressed. Additionally, when the molecule-metal surface distance is varied keeping all other molecular and metal parameters constant, this behavior is mitigated due to the spectral shift associated with the same molecule-plasmon interaction, making the observation of Rabi splitting more challenging.

description: The present study examined the self-perceived body state, ideal body state, perceived other-sex ideal state, and actual other-sex ideal state for a number of body characteristics in white, heterosexual, undergraduate males and females. The relative strength of the ideal choices were also indicated by the sexes. The characteristics examined were: body size, weight, muscularity, height, hair color, hair length, eye color, and female breast size. Discrepancies between the self-perceived body state, the ideal body state, and perceived other-sex ideal body state were examined for the sexes. Also investigated were the differences between the perceived other-sex ideals and the actual other-sex ideals. The influences of sex-role identity and Appearance Orientation on ideal ratings were explored. It was determined that men and women have a number of discrepancies between their self-perceived body state, their ideal body state, and their perceived other-sex ideal body state. Women had more discrepancies than men. Both sexes had a number of differences between their self-perceived body state and their perceived other-sex preference. Few discrepancies were found for the sexes between their ideal body state and their perceived other-sex ideal body state. Both men and women demonstrated inaccurate perceptions of what the other sex preferred on almost all of the characteristics examined. For a number of body characteristics, men and women differed in the relative strength across their ideal choices. The sexes were found to have preference differences across the types of ideal choices for various characteristics. Although Appearance Orientation and sex-role identity were believed to influence ideal choices, little evidence of this was found. However, Appearance Orientation and sex-role identity did appear to affect strength of preferences for males. Further research in this area is encouraged. Larger samples should be employed in the future. Also recommended is the examination of the influences of age, race, and sexual orientation on ideal choices and preference strengths.

description: We combine small angle scattering experiments and simulations to investigate the internal structure and interactions of composite Poly(N-isopropylacrylamide)-Poly(ethylene glycol) (PNIPAM-PEG) microgels. At low temperatures the experimentally determined form factors and the simulated density profiles indicate a loose internal particle structure with an extended corona, that can be modeled as a star-like object. Increasing temperature across the volumetric phase transition, the form factor develops an inflection which, using simulations, is interpreted as arising from a configuration in which PEG chains are incorporated in the interior of the PNIPAM network. In this configuration a peculiar density profile characterized by two dense, separate regions is observed, at odds with configurations in which the PEG chains reside on the surface of the PNIPAM core. The conformation of the PEG chains have also profound effects on the interparticle interactions: While chains on the surface reduce the solvophobic attractions typically experienced by PNIPAM particles at high temperatures, PEG chains inside the PNIPAM network shift the onset of attractive interaction at even lower temperatures. Our results show that by tuning the morphology of the composite microgels we can qualitatively change both their structure and their mutual interactions, opening the way to explore new collective behaviors of these objects.
