"The centre of pleasure and magnificence": Paul and Thomas Sandby's London
In this essay John Bonehill examines Six London Views, a set of prints published between late 1766 and early 1768 by Edward Rooker, mainly after designs by Paul and Thomas Sandby. These prints are considered in relation to rival pictorial visions of the city as well as to architectural debates regarding the capital's preservation and modernizationâits pasts, presents, and futures. These London views advanced the argument for a more âmagnificentâ and scenographic cityscape, one indebted to the grand visions of court architects of the past, preeminently Inigo Jones, and more befitting the imperial age ushered in by the victories of the Seven Years' War
Designs on the landscape: Paul and Thomas Sandby in North Britain
In 1747, a young Paul Sandby took up the role of chief draughtsman on the Military Survey of North Britain undertaken by the Board of Ordnance. This ambitious mapping project was part of a series of measures directed at âpacifyingâ the Scottish highlands in the wake of the Jacobite rebellion of 1745, linking with a large-scale road building programme and the planning of new settlements. In his work for the Board, Sandby was employed in projecting as well as recording the progress of these improvements. Taking forward issues the authors first addressed in the catalogue to a 2009 exhibition of Sandbyâs art, this article reviews the artistâs work in North Britain and its role in the remaking of the nation state, locating it in relation to various designs on the landscape. It focuses on drawings made in connection with âUtopianâ improvement schemes for planned settlements: firstly, in prospects of the west-coast town of Inveraray, made in collaboration with Sandbyâs elder brother Thomas, and secondly, in a view of a surveying party at work near Loch Rannoch, in the southern highlands. They are works which open up wider perspectives on the roles of drawing and design in the period, raising questions too about the significance and scope of the âtopographicalâ as a genre
HR consultant wellness in the South African working environment
This dissertation focuses on the positive and negative influences on wellness in the South African working environment, as well as three of the aspects that constitute todayâs modern definition of wellness, namely: psychological, social, and physical wellness, as perceived by HR consultants in the target organisation. The results of the study determine what the main positive and negative influences on the wellness of HR Consultants were as perceived by the studyâs participants. Nature of the Job, State of Mind, and Relationships are some of the most significant identified categories because they best reflect what is perceived to affect each aspect of HR Consultant wellness in the working environment.Dissertation (MCom)--University of Pretoria, 2012.Human Resource Managementunrestricte
Staging grounds: Loutherbourg and Warley
In 1778, Philippe-Jacques de Loutherbourg began work on a pair of companion pictures marking George III's attendance at a spectacular military review on the broad expanse of Essex wasteland that was Warley Common. Scholars of the painter's art have largely overlooked these ambitious, large-scale landscapes, but their commission and subsequent display at the Royal Academy played a key role in advancing Loutherbourg's career. Strikingly novel, the paintings attracted a good deal of critical attention for their curious mix of the patriotic and the satirical, the topographic and the scenographic. Taking its cue from this latter stage set-like quality, this essay situates Loutherbourgâs Warley scenes in relation to a series of dramatic spaces, moving from the âbattlefieldâ depicted to the London stage to the Academy exhibition room, highlighting a series of connections and interactions that shed new light on the performativity of Georgian art, culture and spaces of display
Use of human resource information systems in the measurement of non-financial organisational success factors
Orientation: Organisations make use of human resource information systems (HRISs) to store data
and assist with the processing of employee and other related information. This data can be a great
source of information on what is happening within the organisation, but it does not appear to be
utilised by industrial and organisational psychologists and organisational development practitioners
when designing interventions to assist organisations. According to Schultz and Schultz (2014), the
relationship between industrial psychology and systems, specifically the relationship between
human factors and technological design factors, is an important area of research for industrial and
organisational psychologists. No existing questionnaire or model in South Africa, however, could be
found on the use of HRIS data in providing an indication of organisational success.
Research purpose: The general aim of the research was to develop a scientific model of
organisational success factors that could be derived from HRISs and then used in organisational
development Initiatives.
Research methodology: A questionnaire was developed on the basis of the recommended processes
in the literature. This included (1) a review of the literature to determine possible organisational
success factors and their possible measures, (2) developing an initial questionnaire based on the
literature review, (3) conducting a pilot study for the questionnaire with willing participants to
enhance its readability and ease of completion, (4) enhancing the questionnaire based on the pilot
study and additional inputs received, (5) administering the questionnaire to the target population,
and (6) conducting statistical analysis. The HRIS model was developed by utilising the results of the
first phase of the statistical analysis and the partial least squares structural equation modelling (PLS SEM). The questionnaire was developed on the basis of a sample of 118 employees in the Human
Capital and Operational Excellence Departments within the organisation that has several companies
and operates in the automotive and industrial sectors in which the research was conducted.
Main findings: The study resulted in the development of a psychometrically sound questionnaire
and a model of organisational success. The following 11 empirically validated constructs were identified: (1) organisational commitment and job satisfaction, (2) organisational learning and
knowledge management, (3) human resource information systems, (4) mature business processes,
(5) transformational leadership, (6) authentic leadership, (7) ethical leadership, (8) overall leadership
influence, (9) organisational culture, (10) employee engagement, and (11) change capability.
Additionally, the model that was developed should provide practitioners with a blueprint on how to
utilise HRISs and the data they house more effectively in informing and designing interventions to
enhance organisational performance.
Contribution/value-add: The main contribution of this study was the development of a valid and
reliable questionnaire on the use of HRIS data to provide an indication of organisational success, as
well as the development of a model for this purpose. Specific driver constructs, namely human
resource information systems, organisational commitment and job satisfaction, and organisational
learning and knowledge management were identified that could, to a certain extent, provide an
indication of other constructs in the model. This could contribute to the use of HRIS data by
industrial and organisational psychologists and organisational development practitioners in the
design of more targeted interventions to assist organisations.Industrial and Organisational PsychologyD. Phil. (Psychology
Enhancement of the antigen-specific cytotoxic T lymphocyte-inducing ability in the PMDC11 leukemic plasmacytoid dendritic cell line via lentiviral vector-mediated transduction of the caTLR4 gene.
The aim of the present study was to enhance the efficiency of leukemia immunotherapy by increasing the antigen-specific cytotoxic T lymphocyte-inducing ability of leukemia cells. The leukemic plasmacytoid dendritic cell line PMDC05 containing the HLA-A02/24 antigen, which was previously established in our laboratory (Laboratory of Hematology and Oncology, Graduate School of Health Sciences, Niigata University, Niigata, Japan), was used in the present study. It exhibited higher expression levels of CD80 following transduction with lentiviruses encoding the CD80 gene. This CD80-expressing PMDC05 was named PMDC11. In order to establish a more potent antigen-presenting cell for cellular immunotherapy of tumors or severe infections, PMDC11 cells were transduced with a constitutively active (ca) toll-like receptor 4 (TLR4) gene using the Tet-On system (caTLR4-PMDC11). CD8(+) T cells from healthy donors with HLA-A02 were co-cultured with mutant WT1 peptide-pulsed PMDC11, lipopolysaccharide (LPS)-stimulated PMDC11 or caTLR4-PMDC11 cells. Interleukin (IL)-2 (50 IU/ml) and IL-7 (10 ng/ml) were added on day three of culture. Priming with mutant WT1 peptide-pulsed PMDC11, LPS-stimulated PMDC11 or caTLR4-PMDC11 cells was conducted once per week and two thirds of the IL-2/IL-7 containing medium was replenished every 3-4 days. Immediately prior to the priming with these various PMDC11 cells, the cultured cells were analyzed for the secretion of interferon (IFN)-Îł in addition to the percentage and number of CD8(+)/WT1 tetramer(+) T cells using flow cytometry. caTLR4-PMDC11 cells were observed to possess greater antigen-presenting abilities compared with those of PMDC11 or LPS-stimulated PMDC11 cells in a mixed leukocyte culture. CD8 T cells positive for the WT1 tetramer were generated following 3-4 weeks of culture and CD8(+)/WT1 tetramer+ T cells were markedly increased in caTLR4-PMDC11-primed CD8(+) T cell culture compared with PMDC11 or LPS-stimulated PMDC11-primed CD8(+) T cell culture. These CD8(+) T cells co-cultured with caTLR4-PMDC11 cells were demonstrated to secrete IFN-Îł and to be cytotoxic to WT1-expressing target cells. These data suggested that the antigen-specific cytotoxic T lymphocyte (CTL)-inducing ability of PMDC11 was potentiated via transduction of the caTLR4 gene. The present study also suggested that caTLR4-PMDC11 cells may be applied as potent antigen-presenting cells for generating antigen-specific CTLs in adoptive cellular immunotherapy against tumors and severe viral infections
âThe shops were only made for people who could walkâ: impairment, barriers and autonomy in the mobility of adults with Cerebral Palsy in urban England
Based on research carried out with a group of adults with Cerebral Palsy in Birmingham, UK, we consider the complex inter-relationship between the accessibility of the urban environment for those with impaired gross motor skills, and the ability of these people to lead full and independent lives. Drawing on a framework that considers mobility as movement, meaning-making and political, we demonstrate the reality of differentiated mobility. For those with bodies that function outside the presumed operating parameters of the model subjects of urban design, mobility may be possible, but is often uncomfortable and even dangerous, with significant associated effects for impaired peopleâs autonomy. Our study details social and structural, or design, barriers to peopleâs mobility, demonstrating the inter-connection between individualsâ behaviour and urban design in a manner that questions a clear distinction between the two. We draw upon the notions of emotional work and a commoning approach to mobility in suggesting that further investment in urban accessibility is squarely an issue of social justice
Immunogenicity of targeted lentivectors
To increase the safety and possibly efficacy of HIV-1 derived lentivectors (LVs) as an anti-cancer vaccine, we recently developed the Nanobody (Nb) display technology to target LVs to antigen presenting cells (APCs). In this study, we extend these data with exclusive targeting of LVs to conventional dendritic cells (DCs), which are believed to be the main cross-presenting APCs for the induction of a TH1-conducted antitumor immune response. The immunogenicity of these DC-subtype targeted LVs was compared to that of broad tropism, general APC-targeted and non-infectious LVs. Intranodal immunization with ovalbumin encoding LVs induced proliferation of antigen specific CD4(+) T cells, irrespective of the LVs' targeting ability. However, the cytokine secretion profile of the restimulated CD4(+) T cells demonstrated that general APC targeting induced a similar TH1-profile as the broad tropism LVs while transduction of conventional DCs alone induced a similar and less potent TH1 profile as the non-infectious LVs. This observation contradicts the hypothesis that conventional DCs are the most important APCs and suggests that the activation of other APCs is also meaningful. Despite these differences, all targeted LVs were able to stimulate cytotoxic T lymphocytes, be it to a lesser extent than broad tropism LVs. Furthermore this induction was shown to be dependent on type I interferon for the targeted and non-infectious LVs, but not for broad tropism LVs. Finally we demonstrated that the APC-targeted LVs were as potent in therapy as broad tropism LVs and as such deliver on their promise as safer and efficacious LV-based vaccines
Design of an optimized Wilms' tumor 1 (WT1) mRNA construct for enhanced WT1 expression and improved immunogenicity in vitro and in vivo
Tumor antigen-encoding mRNA for dendritic cell (DC)-based vaccination has gained increasing popularity in recent years. Within this context, two main strategies have entered the clinical trial stage: the use of mRNA for ex vivo antigen loading of DCs and the direct application of mRNA as a source of antigen for DCs in vivo. DCs transfected with mRNA-encoding Wilms' tumor 1 (WT1) protein have shown promising clinical results. Using a stepwise approach, we re-engineered a WT1 cDNA-carrying transcription vector to improve the translational characteristics and immunogenicity of the transcribed mRNA. Different modifications were performed: (i) the WT1 sequence was flanked by the lysosomal targeting sequence of dendritic cell lysosomal-associated membrane protein to enhance cytoplasmic expression; (ii) the nuclear localization sequence (NLS) of WT1 was deleted to promote shuttling from the nucleus to the cytoplasm; (iii) the WT1 DNA sequence was optimized in silico to improve translational efficiency; and (iv) this WT1 sequence was cloned into an optimized RNA transcription vector. DCs electroporated with this optimized mRNA showed an improved ability to stimulate WT1-specific T-cell immunity. Furthermore, in a murine model, we were able to show the safety, immunogenicity, and therapeutic activity of this optimized mRNA. This work is relevant for the future development of improved mRNA-based vaccine strategies K
