Aspects of identity in four novels by Henry James

Henry James's handling of character raises questions about the nature of identity and the formation and definition of self. This study focuses on four of his novels in addressing aspects of identity in Henry James, and it is broadly divided among the following four topics: the relation between self and language; self and place; self and society; and self and deception. The first chapter, on The American, deals with self-definition, language, and the "self-made man," with alternatives of "being" and "doing" as they relate to identity, and with the association of identity, experience, and knowledge. This chapter also discusses the concept of national identity and type, a topic that is explored more fully in the second chapter, on Washington Square, in which nationality, place and social context shape the identity of the characters. The third chapter, on The Awkward Age, looks mainly at the way identity is socially controlled and the way that consciousness and perception work to realize self. Finally, with The Wings of the Dove, identity, dissimulation and social function are connected through a study of that novel's two major women characters. The thesis proposes that Kate Croy's claim to the status of heroine challenges that of Milly Theale; both women consciously create identities in the face of social necessity. In James's representation of character, self proves to be unstable and fluid, dependent on ever-changing consciousness, perception and experience. Identity in Henry James is not a fixed concept or entity; rather it involves continual making and remaking so that any given representation of it is always provisional, true only for the moment and neither fixed nor complete.
AElfric's Letter to the Monks of Eynsham, a Study of the Text and its Sources

Abbot AElfric's monastic customary, the so-called Letter to the Monks of Eynsham (hereafter LME), has never received attention comparable to that lavished on the same author's celebrated Old English homilies and translations; yet the LME contains a rich store of information that promises to deepen our understanding of Anglo-Saxon monastic liturgy and AElfric's authorial methods. The present thesis offers the first comprehensive study of the text and addresses the following issues: (1) The date and milieu of the work. The refoundation of Eynsham Abbey and AElfric's appointment there as abbot are fixtures in the standard accounts of his career. The precise relation of the LME to these events, however, is less sure than has been supposed. The text is not a beginners' guide, as many have assumed, and its composition may have taken place some years after the refounding of the monastery. (2) The manuscript. The LME survives in a single mid-eleventh-century copy alongside texts associated with Archbishop Wulfstan's "Commonplace Book." An analysis of the manuscript provides a few clues about the reception of the LME. Codicological evidence and historical factors call into question long-held notions about the place of the text in Wulfstan's florilegium and alternatively suggest associations with St. Wulfstan II of Worcester. (3) The sources. AElfric's letter draws extensively from two sources, the Regularis concordia of AEthelwold and the Liber officialis of Amalarius of Metz. Close analysis of how AElfric adapts these texts points to some of the liturgical, theological, political, and stylistic concerns that shaped the LME. AElfric's copies of these sources do not appear to have survived, but his verbatim quotation of them occasionally offers clues to the textual traditions to which his exemplars belonged. The techniques by which AElfric recasts his sources in Latin naturally invite comparison to his much better-known methods of translating from Latin into Old English. (4) The liturgy. Because the technical information of the LME is difficult to assimilate, I provide a translation of the entire text, followed by an extensive commentary, chiefly on liturgical matters and interpretive problems in AElfric's customary.
The optimization of iron chelation with deferiprone

Deferiprone is an orally active iron-chelating agent that reduces the body iron burden of chronically transfused, iron-overloaded homozygous beta-thalassemia patients. However, it is unclear how to optimize iron chelation with this drug. I hypothesize that iron chelation by deferiprone can be optimized by matching the mode of administration of deferiprone to the kinetic profile of iron. Hence in patients with chronic iron-overload (thalassemia and sickle cell disease), greater iron chelation will occur when deferiprone is administered more frequently and in smaller doses than it will when the same daily dose of the drug is administered less frequently and in greater amounts. Conversely, in acute iron intoxication, large amounts of the drug will be more effective in chelating iron than smaller, multiple doses. Greater urinary iron excretion (following transfusion) was induced in the homozygous beta-thalassemia patients, when deferiprone was administered every six hours compared to every twelve hours. In the same group of patients (prior to transfusion), similar quantities of urinary iron excretion resulted with the two regimens despite a decrease in the systemic deferiprone area-under-the-curve when the drug was administered every six hours. A significant quantity of fecal iron was excreted by sickle cell disease patients on the deferiprone regimen, and fecal iron excretion varied from 3 to 33% between patients. Deferiprone did have any measurable antiplasmodial effect in asymptomatic malaria patients. Rats receiving a toxic iron meal had a 58% mortality, whereas those animals that received the iron meal followed by IP injections of deferiprone solution had a mortality of only 15%, an increase in urinary iron excretion. The decrease in body iron load was reflected in the iron stains of the gastrointestinal organs. The administration of a single IP injection of deferiprone solution induced greater urinary iron excretion than did (same-dose) four IP injections of deferiprone. Optimal iron chelation by deferiprone is dependent on the kinetic profile of the iron. In the chronically-transfused patients, sustained levels of deferiprone are necessary to optimally chelate the sustained levels of non-transferrin-bound iron that are present in the serum. Conversely, in acute iron intoxication, a large administration of deferiprone is needed to chelate the circulating iron and prevent its entry into cells.
Doing things in your head, a philosophical essay on mental action

John B. Watson distinguished between the objective study of human behavior and the subjective study of consciousness. Like Watson I hold that human behavior is the subject of psychology; but there are problems with Watson's distinction. First, most observable human behavior is itself conscious; and second, some conscious behavior does not involve overt movement at all. Many behaviors, indeed many actions, are performed 'in the head'. I advance a theory in which behavior is a single general kind; mental and overt behavior are merely two interestingly distinct forms. Most behavior depends on prior events in which the behaver learns from sensory experience. Thus I develop a naturalizing theory of representation (modeled on artistic representation) which treats the brain as a medium in which representational structures are formed when we interact with the world around us. These representational neuro-structures are utilized in the production of behavior. The resulting mental and overt behaviors are likewise representational and can be interpreted as meaningful. The medium theory of representation provides a framework in which to understand mental and overt behaviors. Mental behaviors differ from overt behaviors in that they involve the active suppression of bodily movement. Suppression is, in my theory, central to the distinction between behavior and action; and thus, to my account of rudimentary action and the closely related mental behavior of desiring, and to more complex forms of action, including 'situated' behaviors, speech acts, deliberate action and mental acts. Finally I turn to the things we do 'in our heads', and the varied consequences of the different ways and circumstances in which we perform these mental acts. The consequences that are of greatest interest concern our conceptions of agency and the mind. Here it is of central importance that we learn to internalize behaviors within the context of the overt practices and activities that constitute a society. This approach to human behavior yields a picture, not of a mind, but of a mental life which can take on many forms. The dominant forms of our mental life are best understood within the context of the social environment in which we develop.
Reactions in mesoscopic liquid clusters

Proton transfer reactions within a proton-ion complex embedded in a liquid cluster composed of dipolar molecules, and the dissociation reactions of (LiCl$\sb2\rbrack\sp-$ in liquid water clusters are examined. The clusters under investigation are large with linear dimensions in the nanometer regime. The rates and mechanisms of proton transfer are studied using adiabatic and nonadiabatic methods for mixed quantum-classical systems and path integral techniques. The rates and mechanisms of the (LiCl$\sb2\rbrack\sp-$ complex dissociation reactions are studied using classical molecular dynamics methods. The solvent structure that exists in the cluster as a result of the surface forces and finite size gives rise to a coupling between the solvent and the proton-ion complex in the (LiCl$\sb2\rbrack\sp-$ system which differs from that in the bulk. Features pertinent to the finite sizes of the systems that enter the reaction mechanisms are the lack of translational invariance of the cluster environment, shape fluctuations, surface forces and large density gradients in clusters compared to those in the bulk.
Investigating mode split for the work trip, role of relative level of service and interaction with mobility dimensions

This study has two objectives. The first objective is to investigate the role that relative level-of-service (LOS) characteristics of travel modes play in explaining the heterogeneity in mode split for the work trip. The investigation is carried out through a comparative analysis between mode split models with and without relative LOS variables. The analytical tool used in developing the models is a relatively new statistical procedure for non-parametric analysis of data, referred to as Classification and Regression Trees. The results show that relative LOS characteristics explain a modest portion of the mode split heterogeneity. The results also show that mode split appears to vary with relative LOS at a higher rate for trips in corridors where the transit service is superior to or comparable with the auto service than for trips in corridors better served by auto. In contrast, auto ownership appears to vary with relative LOS at a higher rate for trips in corridors better served by auto. The second objective of this study is to investigate interactions between mode split for the work trip and the mobility dimensions of residential location, employment location and auto ownership. This is done through an exploratory analysis, in which tabulations and plots of each dimension are examined separately, resulting in a multi-dimensional picture or the interactions. Travellers that have different mobility patterns are observed to have distinct characteristics. Specifically, households with different compositions or at different stages in life cycle have different mobility patterns. The observations suggest that mode choice appears to be a household decision made together with other mobility decisions, and that these decisions are highly dependent on household composition and/or stage in life cycle. The study discusses the implications of the findings in transportation planning. Also, the study recommends some modifications to the modelling practice of mode split in light of the results of the investigation.
Characterization of a repressor element and purification of its cognate DNA-binding protein for the transcription of the genes for the antifreeze proteins in wolffish (Anarhichas lupus)

Many marine fish secrete antifreeze proteins (AFP) into their sera to protect them selves from freezing in icy sea water. Four different types of AFPs have been characterized, antifreeze glycoprotein and AFP type I, II and III. The transcriptional control for the Type III Antifreeze protein (AFP) genes is poorly understood. In this present study, all known Type III genes and flanking DNA sequences were compared, revealing that the Type III AFP genes from wolffish (Anarhichas lupus), ocean pout (Macrozoarces americanus) and Antarctic eel pout (Lycodichthys dearborni) have common core sequences. These core segments are intervened by unique regions, which are present in some, but not in all of the genes aligned. A region from wolffish AFP genes, located between $-$220 to $-$90 bp upstream from the transcription start site, was previously characterized to repress transcription. This segment falls into two different core regions, with a unique segment between. Two out of the three characterized wolffish sequences, have two 12 base pair repeated elements in tandem, called "b" elements within this described repressor region. The first repeated "b" element, is within a core region, and therefore is present in all Type III AFP flanking sequences. The second repeated "b" element is unique to the two wolffish sequences. The $-$220 to $-$90 bp fragment is shown to interact with proteins from nuclear extract of various sources with strongest interaction in liver tissues. Several proteins appear with the $-$220 to $-$90 bp DNA segment. The "b" elements also interact with nuclear proteins from the liver. Furthermore, the repressor region is shown here to be due to the two "b" elements, which mediate a strong repression of transcription, presumably by interacting with the general transcription factors. Several additional DNA-binding sites are also identified within this segment. To further distinguish the nature of the repressor element, its putative binding protein(s) was purified and characterized. Three proteins of different size appear to interact with the "b" element in liver tissue. These proteins, termed pBB for protein binding to "b" element, are between 34 and 38.5 kDa in size. The size of the purified proteins is in good agreement with cross-linking experiment performed on the crude nuclear extract. All three proteins appear to be rich in glutamine and glutamic acid residues, which are commonly found in repression and activation domains of trans-acting factors. Finally, all three proteins have identical N-terminal sequences, raising the possibility that the difference in molecular weight might be due to micro-heterogeneity, alternative splicing of the mRN. Both the elements and the DNA-binding proteins described here appear to be novel, and have not been previously characterized.
Quadrature bandpass delta-sigma modulation for digital radio

Considerable research effort in the field of microelectronics pushes towards the realization of fully monolithic, chiefly digital, RF transceivers--with the ultimate objective being the implementation of small, inexpensive, low-power communication devices that are robust, testable, and capable of handling multiple communications standards. Two-path zero-IF architectures and single-path bandpass-$\Delta\Sigma$-based architectures strive to attain these dual goals, but neither effectively achieves both. This thesis proposes a low-IF receiver architecture, which, with modern quadrature image-reject mixers and strategic IF placement, offers a viable solution for realizing digital, monolithic receivers. A critical, and heretofore non-existing, component of such a system--and indeed of any receiver that uses image-reject mixing to alleviate off-chip filtering requirements--is one that efficiently performs bandpass A/D conversion on quadrature signals. A quadrature variant of a bandpass delta-sigma ($\Delta\Sigma$) modulator is thus proposed, which offers significant theoretical and practical performance advantages over the alternative of a pair of traditional bandpass $\Delta\Sigma$ modulators. The design of the transfer functions, systems and circuits needed to realize quadrature $\Delta\Sigma$ modulators are explored. Non-ideal effects are examined, interpreted, and combatted. Unique code-driven layout techniques facilitate the implementation of a fourth-order prototype quadrature bandpass $\Delta\Sigma$ modulator in a 0.8-$\mu$m CMOS process. Clocked at 10 MHz, the IC converts narrow-band 3.75 MHz I and Q inputs, attaining 62-dB maximum SNDR and 67-dB dynamic range--true 10-bit accuracy--in 200-kHz (GSM) bandwidth. Moreover, the IC clearly demonstrates many of the theoretical predictions. Power consumption is 130 mW at 5 V. Die size is 2.4 x 1.8 mm$\sp2$.
Non-vanishing of modular L-functions with large level

This thesis studies the non-vanishing of the twisted modular L-function $L\sb{f}(s, \chi)$ for a fixed weight k, varying level N and a fixed Dirichlet character $\chi$ (mod q) where $(q, N) = 1.$ Here f is a newform of level N. Let ${\cal F}\sb{N}$ be the set of newforms of weight k and level N. (1) It is proved that$$C\sb{k}{N\over{(\log\ N)\sp2}}\le \sharp\{f\in{\cal F}\sb{N};\ L\sb{f}({k\over 2},\ \chi)\ne 0\}$$for prime N large enough. Here, $C\sb{k}$ is a constant depending only on k. (2) It is proved that for real Dirichlet characters $\chi\sb1$ and $\chi\sb2$ with $\chi\sb1\chi\sb2({-}N) = 1$ and $k > 2$,$$C\prime\sb{k}{N\over{({\rm log}\ N)\sp6}} \le \sharp\{f \in {\cal F}\sb{N};\ L\sb{f}({k\over2},\ \chi\sb1) L\sb{f}({k\over2},\ \chi\sb2) \ne 0\}$$for prime N large enough. Here, $C\prime\sb{k}$ is a constant depending only on k. (3) In the case $k = 2,$ it is proved that under the assumption of the Generalized Riemann Hypothesis for $L\sb{f}(s)$ and the assumption of $L\sb{sym\sp2(f)}({3\over2} + it)\ll N\sp{{1\over2}{-\eta}},$ for some $\eta\ >$ 0$$cN \le\sharp\{f\in {\cal F}\sb{N};\ L\sb{f}(1)= 0\ and\ L\prime\sb{f}(1)\ne 0\}$$for prime N large enough. Here $L\prime\sb{f}(s)$ is the derivative of $L\sb{f}(s)$ and $c\ (0 < c < 1)$ is an absolute constant. During the course of the proof of (3), a "semi-orthogonality" relation between the Fourier coefficients of ${\cal F}\sb{N}\sp-$ (newforms with root number $-$1) is given. Using this relation and the symmetric square L-function properties, upper bounds for$$\sum\sb{f\in{\cal F}\sb{N}\sp-}{{rf}\over{4\pi\langle f,\ f\rangle}},\ and\ \sum\sb{f\in{\cal F}\sb{N}\sp-}\ r\sb{f}\sp{1\over2}$$and asymptotic formula for$$\sum\sb{f\in{\cal F}\sb{N}\sp-}\ \langle f,\ f\rangle$$are obtained, where $r\sb{f}$ is the vanishing order of $L\sb{f}(s)$ at $s = 1$ and $\langle .,.\rangle$ denotes the Petersson inner product.
Tyrosine requirements and resting energy expenditure in patients with phenylketonuria

Tyrosine requirements and resting energy expenditure (REE) were determined in subjects with Phenylketonuria (PKU). In order to study amino acid kinetics in children, a noninvasive method was developed in 16 adults which involved oral infusion of stable isotope-labelled amino acids (phenylalanine and lysine) and measurement of isotope enrichment in urine (verified in plasma) and breath. This noninvasive method was incorporated into the Indicator Amino Acid Oxidation protocol in which the oxidation of an infused indicator amino acid (lysine) decreases as the dietary intake of a test amino acid (tyrosine) is increased by increments, until the dietary requirement is reached. In this study, the hypothesis that tyrosine requirements in PKU account for 45% of the aromatic amino acid requirement was tested. The mean daily tyrosine requirement determined by lysine oxidation and F$\sp{13}$CO$\sb2$ were 16.3 and 19.2 $\rm mg\cdot kg\sp{-1},$ respectively. These values represent $\sim$40 to 45% of the aromatic amino acid intake and are $\sim$5 times lower than current recommendations. This study is the first application of an amino acid oxidation technique in determining amino acid requirements in a pediatric population and in subjects with an inborn error of metabolism. With respect to REE, it was hypothesized that excessive weight gain in PKU may in part be attributable to decreased REE. Twenty-three subjects with PKU, 7 subjects with MSUD and 28 control subjects had REE and body composition assessed by indirect calorimetry and bioelectrical impedance analysis, respectively. After adjusting for lean tissue differences, REE was determined to be reduced in the PKU group (279 $\rm kJ\cdot d\sp{-1}).$ Reduced REE in PKU may contribute to their tendency to be overweight.
The radical gesture, feminism and performance art in the 1970s

This study examines the relationship between the in surgent feminist movement and the development of feminist performance art in North America during the 1970s. The thesis argues that feminist performance was instrumental in challenging the premise that art is an autonomous activity separate from the social and political conditions of everyday life. By adapting the feminist axiom that the personal is political to the practice of art making, feminist artists used performance as a form of cultural intervention in which personal experiences, narratives and representations were drawn upon to contest the prevailing social and political arrangements of gender. In so doing, feminist performance artists played a decisive role in reshaping our understanding of the political and in redefining the relationship between art and politics during this period. This thematic study of the origins and development of North American feminist performance within the larger cultural context begins with an overview of the relationship between art and politics in the twentieth century. It traces the ideological shifts that account for the transformation of avant-garde art from a highly politicized to a primarily aesthetic movement in the two decades after World War II, which in turn resulted in a dilemma for many artists as they questioned whether their art could or should engage with the deepening social and political crises of the 1960s. This study goes on to establish how the rise of the feminist movement provided women artists with a means to re-engage art as a political practice. It explores the relationship between feminist politics and the formulation of performance as an art form particularly suited to the needs of feminist artists to reach new audiences and use their art as a weapon to renegotiate their role within the art world and to confront the oppressive effects of sexism in the larger culture. Through discussion of an extensive range of works by individual artists in relation both to contemporaneous and more recent feminist theory, this study seeks to account for the specific ways in which feminist performance art has fundamentally altered our current understanding of aesthetic practice in relation to the social and cultural conditions in which it is embedded.
