Advanced methodology for 103Rh NMR spectroscopy
No full textDespite the ubiquitous presence of rhodium complexes in catalysis, and the favourable 100% natural abundance of the spin-1/2 103Rh nucleus, 103Rh NMR parameters in the literature are notably sparse. This apparent dissonance is in part a consequence of the very low gyromagnetic ratio of 103Rh and hence its dismal NMR sensitivity. In this thesis, we aim to improve the accessibility of 103Rh NMR by developing advanced methodologies, which build upon existing techniques to improve 103Rh NMR sensitivity whilst simultaneously mitigating experimental hurdles associated with the practice. Furthermore, we will broaden the scope of 103Rh NMR by developing methodology to access and study the nascent singlet state in a 103Rh spin pair. To mitigate the poor sensitivity of the 103Rh nucleus, we demonstrate 1H enhanced 103Rh NMR methodology for the rapid acquisition of 103Rh NMR spectra and parameters; including 103Rh relaxation time constants over a range of magnetic fields. Moreover, a scheme is described for suppressing ringing artifacts, a common hurdle in the direct observation of low gyromagnetic ratio nuclei. We employ selective 18O labelling to break the magnetic equivalence of a 103Rh spin pair and facilitate the estimation of the 103Rh-103Rh J-coupling; as well as provide access to the 103Rh singlet state. We present the first measurement of an 18O induced 103Rh secondary isotope shift and report the first instance of singlet order generated in a 103Rh spin pair. The field dependence of both the relaxation of 103Rh longitudinal and singlet spin order is measured via field cycling experiments. We evaluate the rhodium formate paddlewheel complex as a vehicle for sustaining long lived 103Rh singlet order. Through the development of polarisation transfer techniques, we stand to greatly improve the accessibility, sensitivity and scope of the NMR technique for 103Rh nuclei in complexes that exhibit prerequisite heteronuclear scalar couplings
NMR spectroscopy of a <sup>18</sup>O-labeled rhodium paddlewheel complex: isotope shifts, <sup>103</sup>Rh-<sup>103</sup>Rh spin-spin coupling, and <sup>103</sup>Rh singlet NMR
No full textDespite the importance of rhodium complexes in catalysis, and the favorable 100% natural abundance of the spin-1/2 103Rh nucleus, there are few reports of 103Rh nuclear magnetic resonance (NMR) parameters in the literature. In part, this is the consequence of the very low gyromagnetic ratio of 103Rh and its dismal NMR sensitivity. In a previous paper [Harbor-Collins et al., J. Chem. Phys. 159, 104 307 (2023)], we demonstrated an NMR methodology for 1H-enhanced 103Rh NMR and demonstrated an application to the 103Rh NMR of the dirhodium formate paddlewheel complex. In this paper, we employ selective 18O labeling to break the magnetic equivalence of the 103Rh spin pair of dirhodium formate. This allows the estimation of the 103Rh-103Rh spin-spin coupling and provides access to the 103Rh singlet state. We present the first measurement of a 18O-induced 103Rh secondary isotope shift as well as the first instance of singlet order generated in a 103Rh spin pair. The field-dependence of 103Rh singlet relaxation is measured by field-cycling NMR experiments.</p
Harry Collins and the American Art of Dress: 1884-1980
No full textToday when one hears the name Harry Collins very little comes to mind. However, from 1910 to 1950 Harry Collins was a name known across the United States. To simple housewives, first ladies, and stars of the stage and screen that sported his designs, Harry Collins was synonymous with American fashion. A New York designer, author, and philanthropist, Collins was both prolific and celebrated during his nearly fifty-year career as a “dress artist.” His peers included famous turn-of-the-century designers such as Poiret and Lucile as well as later well-known designers such as Adrian, Hattie Carnegie, and Clarie McCardell. Collins often showed alongside these illustrious stars of the fashion world and was seen as their equal. Not only was Harry Collins a designer for the stage, screen, and shop, however, he was also a creative author, critic, and inventor who sought to bring an art to the dress of the everyday American woman. Unlike many of his peers, Collins reached out to a broader audience publishing pieces in Ladies Home Journal and Modern Priscilla as well as a popular book used in Home Economics courses, The ABC of Dress (1923.) To date, Collins has attracted little scholarly attention. This thesis will explore Collins’s multi-faceted career in order to uncover his important role in creating an American style of dress in the early 1910s and 1920s, his most prolific period of design. Decades before the infamous Dorothy Shaver and New York designers of the 1930s and 1940s sought to establish an American fashion, Collins articulated and promoted an American style intended to surpass and sublimate the Parisian monopoly on fashion. As Collins articulated it, the American style was intrinsically linked with a burgeoning national identity. Collins even supported his country and its soldiers through philanthropic works during both World War I and World War II in the realm of fashion, further cementing the connection between the American style and patriotism. While costume historians have heralded the birth of an American style in post WWII America, the first wave of American critics and designers who sought an American mode of dress in the decades just before and after WWI remain understudied. Establishing Collins’ contribution to the formation of an American way of dress in this earlier period helps to illuminate the beginnings of this important movement in design history. Because Collins uniquely bridged the gap between the worlds of high fashion and that of the everyday American woman, he provides an ideal case study to examine the complex intersection of elite patronage and mass culture that enabled American fashion designers to create a new and unique style. Through careful examination of Collins’ identified dresses and his sketches, as well as study of the rich treasure trove of his patents, marketing materials, and copious writings in magazines, newspapers, and trade journals which expressed his ideals, this thesis will construct a greater understanding of Collins’s significant contribution to an American style of dress in greater context to the fashion world in the twentieth-century
The <sup>103</sup>Rh NMR spectroscopy and relaxometry of the rhodium formate paddlewheel complex
No full textThe nuclear magnetic resonance (NMR) spectroscopy of spin-1/2 nuclei with low gyromagnetic ratio is challenging due to the low NMR signal strength. Methodology for the rapid acquisition of 103Rh NMR parameters is demonstrated for the case of the rhodium formate “paddlewheel” complex Rh2(HCO2)4. A scheme is described for enhancing the 103Rh signal strength by polarization transfer from 1H nuclei, which also greatly reduces the interference from ringing artifacts, a common hurdle for the direct observation of low-γ nuclei. The 103Rh relaxation time constants T1 and T2 are measured within 20 min by using 1H-detected experiments. The field dependence of the 103Rh T1 is measured. The high-field relaxation is dominated by the chemical shift anisotropy mechanism. The 103Rh shielding anisotropy is found to be very large: |Δσ| = 9900 ± 540 ppm. This estimate is compared with density functional theory calculations

A TRANSLATION ANALYSIS OF COLLOQUIAL EXPRESSIONS IN THE CHILDREN’S S TORYBOOK ENTITLED THE SECRET LIFE OF MS WIZ BY TERENCE BLACKER
No full textThe focus of this research is the translation analysis of colloquial
expressions in the children’s storybook entitled The Secret Life of Ms Wiz by
Terence Blacker. The objectives of this study are to find out the types of
colloquial expression, to find out the translation techniques used by the translator
to translate colloquial expression, and to know the effect of the translation
techniques used on the quality of the translation in terms of accuracy and
acceptability.
This research used a descriptive-qualitative and quantitative method and
was designed as a single-embedded case study. It used document and informant
sources. Total sampling was applied to collect the data. The data were obtained by
using content analysis and questionnaire. In content analysis, the researcher
collected the data by selecting the dialogues among the characters containing
colloquial expressions. The data found were 247 data. The form of questionnaire
was a close-open ended. The questionnaire was distributed to three raters who are
translation experts.
The research findings from 247 data show that: (1) there are four types of
colloquial exp ressions found in the children’s storybook. They are 45 data of
single words, 2 data of clipped words, 191 data of contractions, and 9 data of
verb-adverb combinations; (2) there are eleven translation techniques found in the
children’s story book. They are adap tation (2 data), amplification (15 data),
borrowing (12 data), calque (43 data), generalization (one datum), literal
translation (27 data), modulation (12 data), reduction (137 data), deletion (15
data), transposition (29 data), and synonym (9 data); (3) the quality translation of
colloquial expression in the children’s storybook, The Secret Life of Ms Wiz, are
(a) from the accuracy point of view, there are 230 or 93.1% accurate data, 16 or
6.5% less accurate data, and one or 0.4% inaccurate datum. The average score of
the mean for accuracy is 1.08 meaning that the translation is accurate; (b) from the
acceptability point of view, 226 data or 91.5% are acceptable, 13 data or 5.3% are
less acceptable, and 8 data or 3.2% are unacceptable. The average score of the
mean for acceptability is 1.12 meaning that the translation is acceptable; (c) the
most accurate technique is reduction which contributes the major data (132 data)
of 230 accurate data. The least accurate technique is deletion which contributes
one inaccurate datum of one inaccurate datum found; (d) the most acceptable
technique is reduction which contributes the major data (135 data) of 226
acceptable data. The least acceptable technique is borrowing which contributes the
major data (7 data) of 8 unacceptable data.
This research can be used as an input for lecturers to give the
understanding about colloquial expression to the students. This research is
expected to give additional information for students, especially English
Department students, about colloquial expression that can improve their
knowledge. Hopefully, there will be further research of colloquial expression
The Embodied versus Embedded Versions of Expertise
No full textThere is a long and unsettled debate between Hubert Dreyfus and Harry Collins regarding embodiment and its connection to expertise. On the one hand, Dreyfus—as an existentialist philosopher—puts emphasis on the phenomenological aspects of the human body and its implications. On the other hand, Collins—as a sociologist of scientific knowledge—stresses the sociological aspects underlying human expertise. To Collins, Dreyfus’ phenomenology is “asociological” while to Dreyfus, Collins’ sociology is phenomenologically “disembodied.” The purpose of this chapter is to disentangle the differences between the two positions and offer a solution to the debate. To this end, the author analyzes the attempt of automating human perceptual skill in industry through a “case study”: the automation of a ball mill. If automation is successful in replacing human beings and their bodies, the sociological view is correct and the phenomenological is wrong—and vice versa.</p
Reversed perspectives : a re-examination of the later novels of William Wilkie Collins
No full textAlthough a considerable amount of research has been done on Collins's sensation fiction, very little
critical attention has been paid to his later novels. Of those critics who have chosen to consider his
post-1870 fiction, the majority have dismissed it as so inferior to his early works as to be best
passed over as quickly as possible. Some feel that, without Dickens to guide his pen, Collins was
mcapable of writing anything worth reading; others suspect that the influence of Charles Reade was
as detrimental to Collins's talent as Dickens's had been beneficial; yet more deCided that laudanum
had fogged both his mind and his literary imagination. The purpose of this thesis is to refute these
claims, and to establish that Collins's later works remain of great interest from both a literary and a
social point of view.
The thesis is divided into seven sections-an Apology, an Introduction, four chapters, and a
conclusion.
The Apology sets out to examine the modern hostility towards the novels written in the last two
decades of his life, and to show how this frequently varies from contemporary opinion. As I do not
ascribe to the theory that Collins's novels reveal a steady decline over the years, I have chosen not
to adopt a chronological examination of his works, but rather a thematic one, which illustrates the
consistency of his philosophy.
The Introduction attempts to show that the difference between what is popularly called Collins's
'sensation' fiction and his 'thesis' novels is not so hard and fast as has often been maintained. It
also introduces the ideas which will be developed throughout the thesis, namely that, by the
sublation of many of the binary oppositions we have come to connect with Victorian literaturemasculine/
feminine, good/evil, hero/villain-Collins's works provide a reversed perspective on his
society.
Chapter 1, 'Good Girls', conSiders Heart and Science (1883), The Two Destinies (1876), and Man and
Wife (1870). The second half of the nineteenth century was, for women, a time of upheaval; the
Angel in the House had been superseded by her more dynamic and independent sister, whose
inadequacy as a role-model was a frequent theme in much of the literature of the time. Whilst
society was attempting to maintain the status quo by demanding that men be men and women
subservient, these three novels stand out as defying-or, at least, ridiculing-convention on almost
all gender-related levels.
Chapter 2, 'Fallen Women', concentrates upon The Evil Genius (1886), The New Magdalen (1873), and
The Fallen Leaves (1879). Collins was not the only author to deal with the subject of women who
transgressed the moral code, but he was one of the few who had the courage to stand by his fallen
women until the end. Rather than sentencing them to a penitential death, he allows them, reformed
and unsullied by their previous degradation, to marry and reclaim their place in society. Moreover,
he also shows that it is frequently those representatives of respectable society whose actions and
attitudes are much more at fault than those of the women they choose to censure.
Chapter 3, 'Wicked Creatures', is a long chapter which analyses '[ Say No' (1884), Blind Love (1890),
The Legacy of Cain (1888), and Jezebel's Daughter (1880). Collins's deep-seated belief in the duality
of human nature, which has already been suggested in the previous chapters, is here more fully
explored. Just as his 'heroines' have been seen to defy their conventional roles, rising gracefully
above the tribulations of pregnancy, prostitution, and persecution, so too do his villainesses flout
the rules by which such wicked creatures should more properly be governed. His household devils
are no more wholly demonic than his domestic angels are wholly sublime.
Chapter 4, 'Other Men', discusses Poor Miss Finch (1872), The Black Robe (1881), and The Law and The
Lady (1875). Not only were women expected by contemporary society to comply with an ideal, but
men also found themselves being exhorted to conform to an active and dominant masculine
archetype. The novels examined in this chapter shows the consequences of the failure to live up to
these frequently impossible standards. Rather than adhere to the binary oppositions of
selfless/selfish, wise/foolish, strong/weak, Collins presents his reader with composite figures who
are, perhaps, truer to human nature than literature usually allows.
The ConclUSion draws together the threads of the previous chapters. It also looks at Collins as a
nineteenth-century writer with surprisingly modern ideas, and examines Collins's literary legacy,
which is more usually to be found in the field of popular fiction
