Samuel Lowry Latimer, Jr. Papers - Accession 530
No full textThe personal papers of Samuel Lowry Latimer, Jr. (1891-1975) include insurance, financial and tax records, various state-related pamphlets, photographs (mainly from The State newspaper) and postcards, and galley proofs of Three Scores and Ten, a history of The State written by Mr. Latimer (published in 1970 under the title The Story of The State and the Gonzales Brothers, see appendix #2). Also included are items of personal and business correspondence of Mr. Latimer and Major McDavid Horton (1884-1941) (editor of The State from 1938 to 1941), various personal items and memorabilia from Mr. Latimer’s two trips abroad, newspaper clippings and articles relating to or published in The State, critiques of The Story of The State and the Gonzales Brothers done by Mrs. Albert D. (May) Oliphant, and several miscellaneous newspaper articles. One of the major subjects of the collection is founding of The State newspapers and the Gonzales Brothers. The Gonzales brothers are Narciso Gener Gonzales (1858-1903), Ambrose Elliott Gonzales (1857-1926), and William Gonzales (1866-1937) and the former two founded The State newspaper in Columbia, SC in 1891. Narciso would later be gunned down on January 15, 1903 (he died four days later) by James H. Tillman. James Tillman was Lieutenant Governor of South Carolina (and nephew of SC Senator Benjamin Tillman) and was a frequent target of criticism by the paper. Tillman would be acquitted by a jury despite many witnesses and received no punishment.https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/1623/thumbnail.jp
A more comprehensive and commanding delineation: Mary Shelley's narrative strategy in Frankenstein
No full textThis thesis argues that the first edition of Frankenstein challenges conventional reading by employing what Simpson in Irony and Authority in Romantic Poetry calls Romantic irony, where the absence of a stable 'metacomment' precludes an authoritative reading. The novel hints at such readings but prevents them. The insights offered by Tropp's Mary Shelley's Monster, Baldick's In Frankenstein's Shadow, Poovey's The Proper Lady and the woman writer and Swingle's, 'Frankenstein's Monster and its Relatives: Problems of Knowledge in English Romanticism' are considered, but none recognises the full implications of the instability deriving from multiple first- person narratives. Clemit's The Godwinian Navel acknowledges the novel's indeterminacy, but reads a specific ideological purpose in it. Paradise Last provides a language to describe the relationship between the monster and Frankenstein, but proves too unstable to fix identity or establish moral value. Similarly, Necessity ultimately fails to provide a stable explanation in terms of cause and effect. The status of nature shifts between foreground and background, never allowing final definition. These uncertainties destabilise knowledge which is compromised by its provisional nature: no authoritative reading is possible, yet the novel has narrative coherence. The reader is encouraged to try to develop a reading the structure prevents. The radical nature of the first edition is highlighted by comparison with the 1831 edition, which removes much of the ambivalence and gives the novel a clearer morality. The novel challenges conventional methods of deriving authority by disturbing the reader's orthodox orientation in the world around him' (Simpson) in order to afford 'a point of view to the imagination for the delineation of human passions more comprehensive and commanding than any which the ordinary relations of existing events can yield' (Mary Shelley)
Intelligent library systems: artificial intelligence technology and library automation systems
No full textArtificial Intelligence (AI) encompasses the following general areas of research: (1) automatic programming, (2) computer vision, (3) expert systems, (4) intelligent computer-assisted instruction, (5) natural language processing, (6) planning and decision support, (7) robotics, and (8) speech recognition. Intelligent library systems utilize artificial intelligence technologies to provide knowledge-based services to library patrons and staff.
This paper examines certain key aspects of AI that determine its potential utility as a tool for building library systems. It discusses the barriers that inhibit the development of intelligent library systems, and it suggests possible strategies for making progress in this important area. While all of the areas of AI research indicated previously may have some eventual application in the development of library systems, this paper primarily focuses on a few that the author judges to be of most immediate significance--expert systems, intelligent computer-assisted instruction, and natural language applications. This paper does not discuss the use of AI knowledge-bases in libraries as subject-oriented library materials
The uses of silence : a twentieth-century preoccupation in the light of fictional examples, 1900-1950
No full textA striking feature of twentieth-century Western cultural history was a
preoccupation with silence. This thesis is a survey of the phenomenon across a
broad range of literary and theoretical discourses actively engaged in the period
in exploring and exploiting silence's expressive and philosophical potential. Its
focus, and unifying principle, is the dynamic resourcefulness of the motif-the
diversity of its uses and significations. The meaning of silence shifts according to
its context and the discourse deploying it. By analysing an array of novels and
theoretical formulations-by writers as diverse as James, Chopin, Conrad, H. D.,
Forster, Lawrence, Faulkner, and Wittgenstein, Benjamin, Blanchot, Hassan,
Macherey, Irigaray, Spivak, Derrida-the mobility of silence as a construct is
exposed.
Silence is identified in the fiction of the period 1900-1950, and its
implications are assessed in the light of the various ways in which its uses were
understood and interpreted by twentieth-century theorists. Theory provides a
heuristic device for the comprehension of the fiction selected for scrutiny whilst
further highlighting the extent of the past century's dedication to the motif.
Fiction and theory are regarded as two different manifestations of a fascination
with silence: fiction dramatizes a commitment to the motif which comes to be
formally registered in theoretical discourse as the century progresses.
After an introductory chapter outlining the expanse of the phenomenon to
be studied, the thesis is divided into two parts illustrating the discrete
implications attaching to the motif: 'Social Silences' and 'Ontological Silences'.
The project questions whether the multiplicity of silence's usage may work to
depotentiate its signifying power; in particular, whether its role in abstract
'ontological' formulations diminishes its force for emancipatory 'social'
discourses. In conclusion, by means of the synchronic organization of the thesis,
silence's import is shown to lie in its resourcefulness rather than in any intrinsic
characteristic it might be thought to possess

Stochastic modelling of daily rainfall sequences
No full textRainfall series of different climatic regions were analysed with the aim of generating daily rainfall sequences. A survey of the data is given in I, 1. When analysing daily rainfall sequences one must be aware of the following points:a. Seasonality. Because of seasonal variation of features of the rainfall process the analysis is done for each month or season separately (see III, 2).b. Non-homogeneity. A rainfall series is called non-homogeneous when it is non-stationary even after elimination of seasonal variation.c. A large fraction of days with no rain.d. Dependence between rainfall amounts on successive days (serial correlation).It is the combination of the last two points which makes the generation of daily rainfall sequences difficult. When dealing with rainfall observations over periods longer than one day this difficulty is mostly obviated because one gets less zeroes and evidence for serial correlation usually disappears. For instance, there is no evidence for serial correlation in monthly data of Dutch stations (see II, 3.1). Besides, theoretical distributions can easily be fitted to the marginal distribution (e.g. the 'loi des fuites', see II, 3.2). The generation of these data is therefore not complicated. For annual totals the Gaussian distribution often fits reasonably well (see II, 2 for Dutch series, and V, 2.1 for foreign series). Departures from normality are found for rainfall stations with a few wet days in a year (New Delhi, Khartoum).Homogeneity of Dutch rainfall series is discussed in Chapter II. It is assumed that non-homogeneities are man-made, e.g. due to a change in rain gauge installation or a change of observer and therefore non-homogeneities usually consist of jumps.A problem when dealing with Dutch rainfall series is the lowering of the rain gauges (from 1.50 m to 0.40 m) during the period 1946-1954 (see II, 4). Due to a smaller wind effect it is expected that such a reduction in height results in larger rainfall measurements. To find a jump in the mean, annual totals of Dutch stations were compared with contemporary totals of foreign stations where no change of height took place. For such a comparison two points are important:a. The distance between the various rainfall stations. In order to obtain a powerful test for a jump, one should choose the stations close together.Therefore Dutch rainfall stations near the Belgian or German border were taken.b. There are other non-homogeneities, for instance, due to changes of site. The consequence of such non-homogeneities is that the estimates of a jump, caused by a reduction of height, may be biased. Moreover, these non- homogeneities give rise to a smaller correlation between the rainfall series and the tests for a jump become therefore less powerful. The influence of local changes can be reduced by taking averages of different stations in a certain area.With regression models and plots of partial sums, a jump in the mean of about 2 per cent is found for stations remote from the coast; for coastal stations the height of the jump can be much larger (even more than 10 per cent), but there is a large variation due to differences in the degree of protection against the wind. The results correspond quite well with those of earlier research by BRAAK (1945).By comparing monthly data of Dutch and German stations in the northern coastal area (see II, 4.2) it is found that the largest jumps occur in the winter season.Another point of investigation is the homogeneity of the Zwanenburg- Hoofddorp (1735-1972) series (see II, 5). Since here there is no nearby rainfall station, with no changes in the way of measuring during the period of observation, the analysis of homogeneity was merely based on the series under consideration. The tests which were considered are less powerful than the ones based on a comparison between changed and unchanged stations. Yet, there is obvious evidence for differences in the means of Zwanenburg (1735-1860) and Hoofddorp (1861-1972). There is no evidence for departures from homogeneity in the Hoofddorp series. Since there is also a poor correlation between the Zwanenburg data and other old rainfall series, these data can be considered useless for present-day hydrological research.Because of the large number of zeroes in daily rainfall sequences, it is suggested to generate first the occurrence of wet and dry days and subsequently the rainfall amounts on wet days. Since small rainfall amounts are often registered as zero it is advisable to call a day wet if its rainfall amount exceeds some specified value. For the Netherlands a threshold of 0.8 mm is advisable (see II, 6); for smaller thresholds there are only a few rainfall stations for which the series of wet and dry days (shortly denoted as wet-dry series) is homogeneous.In Chapter III a model is developed for Dutch rainfall series, using daily data from Winterswijk (1908-1973), Hoofddorp (1867-1971) and Hengelo (1908-1973). Theoretical considerations about the model are given in Chapter IV.With respect to the wet-dry sequences of these series it can be concluded:a. There is no evidence for correlation between the lengths of successive wet and dry spells (see III, 3.1).b. Modifications of the negative binomial distribution (the shifted negative binomial distribution, see III, (3.2) and the truncated negative binomial distribution, see 111, (3.3)) fit the lengths of weather spells well.Seasonal dependence of the parameters of the truncated negative binomial distribution was extensively studied. For a particular type of spell it was shown that it is reasonable to keep one of the parameters, r, constant throughout the year. Further, for dry spells the other parameter, p, can be smoothed according to a moving average scheme (see III, (3.17)); for wet spells seasonal variation of the parameter p can be described by a Fourier series with one harmonic component (see III, (3.12)).With respect to the behaviour of rainfall amounts on wet days the following remarks can be made.a. There is no evidence for correlation between the rainfall amount on the first day of a wet spell and the length of the preceding dry spell (see III, 4.1).b. The first and the last day of a wet spell have smaller means than the other wet days; the smallest mean is found for solitary wet days (see III, 4.2).c. There is some evidence for serial correlation of successive rainfall amounts within a wet spell (see III, 5.1). It is assumed that this serial correlation can be described by a first order moving average process (see III, 6.1).The last two points are most evident during the winter season.A shifted gamma distribution fits the marginal distribution of the rainfall amounts on wet days reasonably well (see III, 5.2). There is no evidence for seasonal variation of the shape parameter; the mean, however, shows an obvious seasonal variation.Though synthetic sequences resemble the historic series with respect to features contained in the model (such as the marginal distribution of daily rainfall amounts and the lengths of wet and dry spells), this is not necessarily true for other features. As examples the correlogram and features of k-day sums ( k = 2, 3, .. .) were considered. This was done for both the wet-dry process and the entire rainfall process.Some features of the rainfall model can be obtained by numerical methods. These features are:a. The cumulative distribution function (cdf) of the number of wet days in a k -day period. Under the assumption of iid rainfall amounts within a wet spell it is not difficult to derive an expression for the cdf of k -day rainfall totals (see IV, 3).b. The correlogram for both the wet-dry process and the entire rainfall process (see IV, 4).c. The variance-time curve of the wet-dry process and of the entire rainfall process (see IV, 5). For large values of k ( k >10) the variance of the number of wet days in a k -day period can be approximated well by an asymptotic formula (Equation IV, (5.36)) involving only the first three moments of the lengths of wet and dry spells. This approximation can also be done for the variance of k -day rainfall amounts when the rainfall totals within a wet spell are iid. For the derivation of the formulas, underlying these numerical calculations, the following assumptions are made.a. The process is stationary.b. The wet-dry process is an alternating renewal process. A definition of this process is given in IV, 2.2.These assumptions turn out to be reasonable when the rainfall process is examined for a particular month or season.For the correlogram. it can be concluded (see III, 6.1):a. There is a good correspondence between the estimated first serial correlation coefficient and the theoretical value for both the wet-dry process and the entire rainfall process. This quantity is usually underestimated when simplifying assumptions are made about the behaviour of rainfall amounts within a wet spell.b. For larger lags the model usually underestimates the serial correlation coefficients of the rainfall process, especially during the winter season. For the wet-dry process the model usually provides a better fit at the higher lags.Closely related to the last point is the fact that the model underestimates the variances of 30-day rainfall amounts (see III, 6.2). During winter and autumn sometimes long wet spells occur with very high intensity (see III, 4.2) which inflate the estimated variances of k -day totals for large values of k .The following remarks can be made on the cdf of k -day sums.a. For the number of wet days in a k-day period there is a good correspondence between theoretical and empirical cdfs (see III, 7.1).b. For the entire rainfall process theoretical cdfs fit well for small values of k ; poor fit may occur for larger values of k (e.g. k = 30). This poor fit usually consists of an underestimation of the probabilities of large values (see III, 7.2.2).Though the cdf was only investigated under the assumption of independent rainfall amounts within a wet spell, it may be expected that the shape of the cdf is hardly influenced when serial correlation between these rainfall amounts is assumed, since the increase in the variance of k-day totals is only very small for a model with serial correlation (see III, 6.2).For the rainfall process it was investigated how different features of the model affect the shape of the cdf of 30-day totals. The main results are:a. The shape of the cdf is hardly influenced by the distribution of the lengths of weather spells (see III, 7.1).b. The shape of the cdf is to some extent not sensitive to the marginal distribution of the rainfall amounts on wet days (see III, 7.2).c. The shape of the cdf is hardly altered when rainfall amounts within a wet spell are assumed to be iid.For Winterswijk (1908-1973) nearly the same results were obtained when the threshold defining a wet day is taken to be 0.3 mm instead of 0.8 mm.Though there are many corrections and supplements in the series of Hengelo (1908-1973) the results for this station correspond quite well to those of the adjacent station of WinterswijkIn Chapter V daily rainfall sequences of stations with a more pronounced seasonal variation than Dutch stations are discussed.The problems encountered for Dutch stations usually arise here too:a. In order to get a homogenous wet-dry series one is often forced to call only those days wet for which the rainfall amount exceeds a rather large threshold (see V, 2. 1).b. Rainfall amounts within a wet spell are often non-identically distributed. Moreover, there usually exists a small serial correlation between rainfall amounts within a wet spell (see V, 2.3).c. The rainfall model underestimates the variances of k -day totals for large values of k (see V, 2.4).Besides, for the series analysed in Chapter V there are some problems associated with dry seasons with no or hardly any rainfall:a. It is often not possible to fit the shifted negative binomial distribution or the truncated negative binomial distribution to lengths of wet spells during the dry season. Since there are no long wet spells during this season, the likelihood equations of these distributions often do not have a solution within the parameter space. In such cases it is possible to fit a one-parameter distribution (geometric, logarithmic series) to the lengths of wet spells (see V, 2.2).b. Dry spells can be quite long. Modifications of the negative binomial distribution sometimes cannot fit the lengths of these spells (see V, 2.2 and V, 3). In such cases it might be advisable to use transition probabilities for the generation of the wet-dry series instead of generating lengths of wet and dry spells. For instance, it was shown, by simulation, that a first order Markov chain describes the right tail of the distribution of the lengths of dry spells well for the station of Alexandria (see V, 3).The generation of synthetic data for Pasar Minggu (Indonesia) was investigated in more detail (see V, 2.5). Special attention was paid to the beginning of both the wet and the dry monsoon. The model can describe the transitions between these seasons quite well.A special problem arises for the rainfall series of Khartoum (1902-1940). For this station there is some evidence for serial correlation in the annual totals and in the annual number of wet days (see V, 3). This serial correlation can be explained by persistence in the lengths of successive wet and dry seasons. It is proposed therefore to generate the beginning and the end of the wet season first. Within a wet season the rainfall process can be approximated by a Bernoulli process for the occurrence of wet and dry days and a shifted gamma distribution for the rainfall amounts on wet days. The probability of a day being wet and the mean of the rainfall amount on a wet day show seasonal variation.The main shortcoming of the daily rainfall model is that it underestimates the variance of k -day totals for large values of k which may result in it poorly fitting the distribution of these totals. It is, however, by no means certain whether this shortcoming is important in practical situations. When dealing with hydrological systems with a long memory one may expect serious problems but studies on such systems can often be based on a time-scale longer than one day. Therefore it is necessary to test the model on some real problems to obtain a better insight into its shortcomings.One may ask whether improvements of the model are possible. For Dutch series the description of the wet-dry process by a seasonal changing alternating renewal process seems reasonable, since the model fits well the probability distributions of the annual number of wet days (see III, 7.2.2) and of the number of wet days in a 30-day period (see III, 7.1). Therefore one must think of a better model for the behaviour of rainfall amounts on wet days. It is impractical to incorporate serial correlation of higher order between rainfall amounts within a wet spell as the effect on the variance-time curve of the process is negligible, because wet spells usually are of short duration. The model could be improved by:a. a random slowly changing mean of the rainfall amounts on wet days. This certainly will increase the variance of k -day totals for large values of k .The main problem of this method is the estimation of the parameters. Another problem can be the choice of the type of distribution for the rainfall amounts on wet days.b. generating a total rainfall amount for a particular period (e.g. a month) and splitting this rainfall amount into the rainfall amounts of the various wet days of that period. Because of the method of generation this model may give a reasonable fit to monthly and annual totals. A disadvantage of this method is that the model contains a large number of parameters.But before thinking of such improvements one must realize that there are large local differences for the variances of 30-day totals (see III, 6.2). It is therefore necessary to analyse a large number of daily rainfall sequences of the Netherlands and its neighbouring countries.For some foreign stations analysed in Chapter V one also has the trouble that for large values of k an alternating renewal process leads to a serious underestimation of the variance of the number of wet days in a k -day period. Research still has to be done to get a better model for such series.<p/
Imagens de Otto Maria Carpeaux: esboço de biografia
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este esboço de biografia procura citar algumas imagens de Otto Maria Carpeaux: construções biográficas de naturezas múltiplas, elaboradas em contextos, por atores e sob condições igualmente díspares. Está constituído a partir de uma visão crítica da História, o que permite que ?outras imagens?, fragmentárias e não monumentais, também tenham espaço. Em diálogo com o princípio da montagem, este esboço apresenta-se em duas partes. Na primeira, Imagens possíveis, estão citadas as imagens elaboradas em vida e post mortem acerca do austríaco-brasileiro que nasceu em Viena em 1900, se exilou no Brasil em 1939 e morreu no Rio de Janeiro, em 1978. Na segunda, Montagens possíveis, apresentam-se duas possibilidades de exercício biográfico: pela leitura alegórica do documentário O velho e o Novo (Otto Maria Carpeaux), entendido como instrumento de intervenção no contexto ditatorial brasileiro e de uma reelaboração biográfica concernentes às suas experiências europeias; e pelo Caderno de imagens críticas, registro dos encontros em Carpeaux pelo meio de imagens críticas produzidas a partir da cesura do presente.Abstract : This biographical sketch attempts to quote some images of Otto Maria Carpeaux: various types of biographical constructions, carried out in different contexts by disparate authors under conditions just as distinct. It stems from a critical view of history, allowing for ?other images? fragmented and non-monumental ? to share the space.In dialogue with the montage principle, this sketch has two parts. The first, Possible Images, quotes the images produced during and after the life of the Austrian-Brazilian, who was born in Vienna in 1900, went to Brazil in exile in 1939 and died in Rio de Janeiro in 1978. The second part, Possible Montages, presents two possibilities of a biographical exercise: through the allegorical reading of documentary O Velho e o Novo (Otto Maria Carpeaux), understood as an instrument of intervention in the Brazilian dictatorship context and as a biographical retelling of the author?s European experiences; and through my Scrapbook of Critical Images, a record of the encounters in Carpeaux through critical images produced from the caesura of the present
The English translation of seventeenth-century French lyric poetry and epigrams during the Caroline period
No full textThis doctoral thesis is the first comprehensive study of contemporary English translations of French lyric poetry during the Caroline period. While there has been extensive study of translations from French literature of other genres, notably drama, translations of lyric poetry have been largely ignored. The thesis examines the translations within the context of literary and cultural trends in France and England during the seventeenth century. Differing cultural tendencies and reader expectations are evident both in the selection of particular poems for translation, and in the changes translators made to their source texts. Chapter one contains background information on the social and literary relations between France and England during the seventeenth century, and an overview of the social and political conditions in which poetry was written in each country. Chapter two investigates where and how translators obtained the texts of the poems they translated, and in particular the use of the recueils collectifs as sources for translations. Chapters three, four and five provide a thematic overview of the most significant and interesting translations. The themes chosen - eroticism, love and nature - constitute those most popular with translators, and the representation of these themes in both the original poems and the translations is closely connected to wider literary and cultural tendencies in both France and England. Having provided a thematic overview of the translations, chapters 6 and 7 examine some of the more technical and linguistic aspects of the practice of translating from contemporary French poetry in Caroline England. Chapter seven studies the translation of the French lyric voice, and the effects of this on the representation of themes, particularly love and nature. Chapter eight examines the English treatment of some aspects of seventeenth-century French prosody, placing these and the changes made by translators in the context of prosodic developments in both France and England. The conclusion highlights patterns identified in translators' handling of the source texts; these draw attention to the literary and cultural differences between France and England in the seventeenth century, and demonstrate that French poetry is altered in English translation to suit the tastes of translators and their intended English readership
Steering Taste: Ernest Marsh, a study of private collecting in England in the early 20th Century
No full textThe primary aim of this thesis is to focus attention on the bourgeois, 'un-named' collector. The driving force behind most museum and art gallery collections of the Victorian and Edwardian period. British museum and art gallery records of gifted collections, bequests and loans usually note their donors. However, with a few notable exceptions, little is known about the collectors, their activities and motivation in making such presentations.
Using the interests and activities of the Quaker miller and collector Ernest Marsh (1843-1945) as a case study, this thesis explores how in the period 1890-1945 a collector came to be a key agent in the construction and manifestation of taste in British Applied Arts and to a lesser degree in the Fine Arts. Through primary visual and documentary evidence of the Marsh home, and reference to contemporary and later commentaries it considers the relative influences of husband and wife on decorating and furnishing the domestic interior, the evolution of taste, and, for Ernest Marsh, its impact upon his artistic interests within the public arena.
By examination of private papers, metropolitan and provincial art gallery and museum archives it also considers evidence of the inter-relationships between donors and curators, and the mutual advantages and disadvantages accruing to both, particularly focussing on the processes in bringing about changes in individual and institutional collecting policy. Further, by review of records of, in particular, the Contemporary Art Society and the Greenslade archive, it examines the degree to which private benefactors and those in public or semi-public office, acting as fund-raisers and spenders exercise influence through patronage of particular practitioners, choice of works and initiating new designs
Encouraging healthy eating behaviours through healthy eating environments. Case of Durham University
No full textThe aim of the study was to perform a formative research by exploring, describing and evaluating at the same time on various factors that influence eating behaviours on campus. The study looks at the situation of Durham University’s college catering system and students’ eating practices, needs, barriers to eat healthy, and explores how the upstream social marketing approach could be advantageous in creating healthy eating environments.
The report notes inconsistencies in strategy implementation within Durham University’s catering initiative to provide students with nutritionally balanced meals and nutritional
information, ultimately trying to promote healthy intakes. Great number of students suggested that meal offering was a barrier to making healthy choice. Most students were
not generally aware of their personal nutritional requirements, indicating a knowledge gap, even for those who considered healthy eating important.
Findings, confirmed through the research, indicate that a considerable element in the creation of healthy eating environments at Durham University’s colleges lies within the provision of nutritionally balanced meals and the adoption of more effective means of communicating nutritional information to students and encouraging them to make healthy choices
