Public worship and practical theology in the work of Benjamin Keach (1640-1704)
No full textThe late seventeenth century was a critical and fruitful period
for the Particular Baptists of England. Severely persecuted following
the Restoration, toleration in 1689 brought its own perils.
Particular Baptists were fortunate in having several strong leaders,
especially the London trio of Hanserd Knollys, William Kiffin, and
Benjamin Keach. Such a small and severely persecuted group as the
Baptists could afford little time for academic pursuits, thus of
necessity most of their theology was practical in nature.
Benjamin Keach (1640-1704) was the most outstanding practical
theologian among the English Particular Baptists of the late
seventeenth century. This dissertation is a study of Keach, in
particular his writings on public worship and practical theology.
Although Keach was a prolific author, he has been almost completely
neglected by scholars.
After a biographical sketch of Keach, this study considers his
writings on public worship and practical theology. In the area of
worship, Keach made two outstanding contributions: First, he was the
most vocal apologist for Baptist views on Baptism of his period.
Secondly, and more importantly, his hymn writing and defense of hymn
singing broke new ground, not just for Baptists, but for English
Protestantism, in general. In addition to his contributions in these
areas, he also dealt with the laying on of hands and the sabbath day
worship controversy.
Keach's contributions to practical theology fall into two main
groups: his writings that concern religious education and those that
deal with polity. In addition to these, Keach's vigorous advocacy of
a high Calvinist soteriology are also considered under the rubric of
practical theology. Keach's most important (although not his most
positive) contribution in this area were his soteriological writings.
Although well within the bounds of orthodoxy, some of the tendencies
in Keach's soteriology were taken up by the following generation of
Baptist leaders and developed into a stultifying hyper-Calvinism that
handicapped Baptist evangelism and missions.
In the conclusion, Keach's contributions to a theory of practical
theology are considered
The temporality of language : Kant's legacy in the work of Martin Heidegger and Walter Benjamin
No full textContrary to the idea that there are fundamental differences between the
work of Martin Heidegger and Walter Benjamin, the thesis shows that
there exists a profound similarity in the direction of their projects, by
exploring how they took up Kant's critical legacy concerning the
temporality of language: the belonging together of language and time.
The ground of Kant's system and of the necessity of systematicity - the
three-fold synthesis which 'generates' time under the direction of
conceptuality - is elucidated via the Second Analogy and the Critique of
Teleological Judgment. It is argued that Kant's understanding of language
and time remains fixed within a circular justification of Newtonian
Science, which prevented him from taking up the critical resources of his
treatment of teleological concepts and applying it to his idea of the
critical system itself. Heidegger's and Benjamin's work may be understood
as taking up the hermeneutic circularity of Kant's philosophical system,
though freeing it from its appeal to a limited time determination. They
both develop notions of a more originary temporality in conjunction with
a linguistic phenomenology. They further allow this more critical
thinking of language and time to reflexively fall back on the writing of
philosophy itself. Their understanding of the temporality of language is
explored through the way 'translation' focuses, in each case, a thinking
of tradition and of linguistic works. The thesis rejects attempts to
separate Heidegger's early work from his later approach, and further
rejects a tendency to focus on Benjamin's style of writing in isolation
from its theoretical basis. The thesis concludes by arguing that the
work of both Heidegger and Benjamin points to a rethinking of Kant's
legacy of the necessity of system, in terms of system as the inescapable
belonging together of language and time
Uniform well-posedness and inviscid limit for the Benjamin–Ono–Burgers equation
No full textAbstractWe prove that the Cauchy problem for the Benjamin–Ono–Burgers equation∂tu−ε∂x2u+H∂x2u+uux=0,u(x,0)=u0(x) is uniformly globally well-posed in Hs (s⩾1) for all ε∈[0,1]. Moreover, we show that as ε→0 the solution converges to that of Benjamin–Ono equation in C([0,T]:Hs) (s⩾1) for any T>0. Our results give an alternative proof for the global well-posedness of the BO equation in H1(R) without using gauge transform, which was first obtained by Tao (2004) [23], and also solve the problem addressed in Tao (2004) [23] about the inviscid limit behavior in H1
Visual discomfort and depth-of-field
No full textThis research was part funded by the BBSRC and EPSRC.Visual discomfort has been reported for certain visual stimuli and under particular viewing conditions, such as stereoscopic viewing. In stereoscopic viewing, visual discomfort can be caused by a conflict between accommodation and convergence cues that may specify different distances in depth. Earlier research has shown that depth-of-field, which is the distance range in depth in the scene that is perceived to be sharp, influences both the perception of egocentric distance to the focal plane, and the distance range in depth between objects in the scene. Because depth-of-field may also be in conflict with convergence and the accommodative state of the eyes, we raised the question of whether depth-of-field affects discomfort when viewing stereoscopic photographs. The first experiment assessed whether discomfort increases when depth-of-field is in conflict with coherent accommodation–convergence cues to distance in depth. The second experiment assessed whether depth-of-field influences discomfort from a pre-existing accommodation–convergence conflict. Results showed no effect of depth-of-field on visual discomfort. These results suggest therefore that depth-of-field can be used as a cue to depth without inducing discomfort in the viewer, even when cue conflicts are large.Peer reviewe
Hundreds of variants clustered in genomic loci and biological pathways affect human height
No full textMost common human traits and diseases have a polygenic pattern of inheritance: DNA sequence variants at many genetic loci influence the phenotype. Genome-wide association (GWA) studies have identified more than 600 variants associated with human traits(1), but these typically explain small fractions of phenotypic variation, raising questions about the use of further studies. Here, using 183,727 individuals, we show that hundreds of genetic variants, in at least 180 loci, influence adult height, a highly heritable and classic polygenic trait(2,3). The large number of loci reveals patterns with important implications for genetic studies of common human diseases and traits. First, the 180 loci are not random, but instead are enriched for genes that are connected in biological pathways (P = 0.016) and that underlie skeletal growth defects (P<0.001). Second, the likely causal gene is often located near the most strongly associated variant: in 13 of 21 loci containing a known skeletal growth gene, that gene was closest to the associated variant. Third, at least 19 loci have multiple independently associated variants, suggesting that allelic heterogeneity is a frequent feature of polygenic traits, that comprehensive explorations of already-discovered loci should discover additional variants and that an appreciable fraction of associated loci may have been identified. Fourth, associated variants are enriched for likely functional effects on genes, being over-represented among variants that alter amino-acid structure of proteins and expression levels of nearby genes. Our data explain approximately 10% of the phenotypic variation in height, and we estimate that unidentified common variants of similar effect sizes would increase this figure to approximately 16% of phenotypic variation (approximately 20% of heritable variation). Although additional approaches are needed to dissect the genetic architecture of polygenic human traits fully, our findings indicate that GWA studies can identify large numbers of loci that implicate biologically relevant genes and pathways
The collapse of single bubbles and approximation of the far-field acoustic emissions for cavitation induced by shock wave lithotripsy
No full textRecent clinical trials have shown the efficacy of a passive acoustic device used during shock wave lithotripsy (SWL) treatment. The device uses the far-field acoustic emissions resulting from the interaction of the therapeutic shock waves with the tissue and kidney stone to diagnose the effectiveness of each shock in contributing to stone fragmentation. This paper details simulations that supported the development of that device by extending computational fluid dynamics (CFD) simulations of the flow and near-field pressures associated with shock-induced bubble collapse to allow estimation of those far-field acoustic emissions. This is a required stage in the development of the device, because current computational resources are not sufficient to simulate the far-field emissions to ranges of O(10 cm) using CFD. Similarly, they are insufficient to cover the duration of the entire cavitation event, and here simulate only the first part of the interaction of the bubble with the lithotripter shock wave in order to demonstrate the methods by which the far-field acoustic emissions resulting from the interaction can be estimated. A free-Lagrange method (FLM) is used to simulate the collapse of initially stable air bubbles in water as a result of their interaction with a planar lithotripter shock. To estimate the far-field acoustic emissions from the interaction, this paper developed two numerical codes using the Kirchhoff and Ffowcs William–Hawkings (FW-H) formulations. When coupled to the FLM code, they can be used to estimate the far-field acoustic emissions of cavitation events. The limitation of the technique is that it assumes that no significant nonlinear acoustic propagation occurs outside the control surface. Methods are outlined for ameliorating this problem if, as here, computational resources cannot compute the flow field to sufficient distance, although for the clinical situation discussed, this limitation is tempered by the effect of tissue absorption, which here is incorporated through the standard derating procedure. This approach allowed identification of the sources of, and explanation of trends seen in, the characteristics of the far-field emissions observed in clinic, to an extent that was sufficient for the development of this clinical device
Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
Jews and gender in British literature 1815-1865.
No full textPhDThis thesis examines the variety of relationships between Jews and gender in early
to mid-nineteenth century British literature, focussing particularly on representations
of and by Jewish women. It reconstructs the social, political and literary context in
which writers produced images and narratives about Jews, and considers to what
extent stereotypes were reproduced, appropriated, or challenged. In particular it
examines the ways in which questions of gender were linked to ideas about religious
or racial difference in the Victorian period.
The study situates literary representations of Jews within the context of
contemporary debates about the participation of the Jews in the life of the modern
state. It also investigates the ways in which these political debates were gendered,
looking in particular at the relationship between the cultural construction of
femininity and English national identity.
It first considers Victorian culture's obsession with Rebecca, the Jewess created in
Walter Scott's influential novel Ivanhoe (1819). It examines Rebecca's refusal to
convert to Christianity in the context of Scott's discussion of racial separatism and
modern national unity.
Evangelical writers like Annie Webb, Amelia Bristow and Mrs Brendlah were
prolific literary producers, and preoccupied with converting Jewish women.
Particularly during the 18'40s and 1850s, evangelical writing provided an important
forum for the construction and consolidation of women's national identity.
Grace Aguilar's writing was an attempt to understand Jewish identity within the
terms of Victorian domestic ideology. In contrast, Celia and Marion Moss, in their
historical romances, offered narratives of female heroism and national liberation,
drawing on the contemporary debate about slavery.
Benjamin Disraeli's construction of a "tough version of Jewish identity was a
response both to the contemporary stereotype of the feminised Jew and to the debate
about Jewish emancipation. It also drew on the virile ideology of the Young England
movement of the 1840s
The modernist angel: Art at the Limits of the Human in D. H. Lawrence, H. D. and Mina Loy
No full textPhDThe subject of this thesis is a figure that might provisionally be called the *modemist
angel'. Focusing on modernist literature, and more particularly on the work of D. H.
Lawrence, H. D. and Mina Loy, it aims to isolate from the many angels found in all periods
and all types of art a historically specific and intellectually coherent paradigm: an angel of
and for its modernist times. A figure of precisely this type could be said to exist in the
form of Walter Benjamin's 'angel of history'. Critics who address the question of the
modern angel in texts by Franz Kafka and Rainer Maria Rilke often do so in conjunction
with the problem posed by the angel of history. Beginning with a chapter on Benjamin,
this thesis nevertheless follows a different trajectory. Over five chapters, it explores a
modernist landscape formed not only by Lawrence, H. D. and Loy, but also by European
and American writers such as A. R. Orage, Allen Upward, Ezra Pound, Wallace Stevens,
Havelock Ellis, Edward Carpenter, Sigmund Freud and Friedrich Nietzsche. Although the
angel that emerges from this investigation might, in some respects, be said to anticipate
Benjamin's later version, this figure is also very different, standing for a project that is
distinctively, and recognisably, modernist in nature. He/she (the sex of the modernist
angel is often open to question) represents an attempt to reconcile the divine
responsibilities of the artist with the material and gendered conditions of being,
specifically of being human, in the modem world. This thesis looks again at the clash of
intellectual paradigms in the early-twentieth century - notably, the confrontation of the
Romantic view of art as a superhuman or sacred undertaking with the psychoanalytical or
evolutionary idea that all human endeavour is underpinned by sub-human motives - and
suggests the angel as a new and instructive figure through which to think the perilous
limits between the human and the divine in modernist literature
Computer analysis of two municipal water systems for demand variations and component modifications
No full textField data were gathered by the author and an associate on two Michigan municipal water systems. The research focuses on using this data and a University of Kentucky computer program to study the effects of demand changes, fire flows, looping, skeletonization, and roughness changes in the systems. The uniqueness in the project lies in the use of field data, especially in the night flow simulations in the Manistique system, and in the simulations involving skeletonization and changing "C" values. The conclusion from one Manistique system simulation was that the repair of all major leakage would decrease the horsepower by over 50% that is required to supply minimum night flows in the system and maintain a full storage tank. Simulations were used to analyze the effects of closing river crossing mains for various demand rates. Fire flow simulations showed vastly different results when identical fire demands were placed first in a remote location in the system and then placed within a grid in the business district. Simulations in the more complex Plymouth Township system showed that system sensitivity response to pipe looping, skeletonization, and "C" coefficient changes was small. Comparisons of pressures generated from the average daily flow simulation with actual field measurements did not indicate good agreement and this can be attributed to pipe flow variations, to conflicts in water system records, to initial skeletonization effects, and to random demand allocation within Pitometer Districts. An extended period simulation was used to model response to demand changes over a twenty-four hour period for the initial conditions of fixed pressures at source locations.Civil and Environmental Engineering, Department o
