On Nietzsche’s genealogical mode of inquiry
No full textThe subject of this thesis is Friedrich Nietzsche’s methodology, the genealogical mode of inquiry, which came to fruition in On the Genealogy of Morals. The precise nature of the genealogy, as a mode of inquiry, is a site of contest amongst scholars, with the central debates pivoting around four questions which arise upon considering the methodology: (1) what is the critical import of Nietzsche’s genealogical mode of inquiry? (2) What form of critique does it take? (3) To whom does Nietzsche address his reflections? And (4) what role, if any, does history play in Nietzsche’s genealogical narratives? Accordingly, this thesis seeks to offer and to defend answers to the central questions that are generated by the consideration of Nietzsche’s methodology.In order to get a foothold into these debates and to provide the boundary within which these disagreements occur the first chapter has as its object of inquiry an examination and evaluation of Nietzsche scholars’ responses to these issues. In chapter two I defend my interpretation against these rival views, and contend that the genealogy takes the form of an immanent critique, and that it is intended, at least, to reach all of Nietzsche’s contemporaries.The adage “genealogy is history correctly practiced” is treated in the remaining three chapters, in which I attempt to morph what appears to be at present an uninformative formulation into an informative one by arguing that for Nietzsche historiography is best seen as a form of artistry. And, this I submit, serves to shed light upon the genealogical mode of inquiry, and to shape the boundary by which the equation of genealogy as methodology with history becomes instructive

Figure 4, Table 1 urn:lsid:zoobank.org:act: E572DF22-EF0F-406D-B053-C20C0A5F84EA Material Examined: Holotype: QM G337611, off the continental shelf of central New South Wales, Australia, Station 88, 30° 15’ 50.4”– 30° 17’ 12.2” S, 153° 52’ 12”– 153° 49’ 48.7” E, 4481– 4401 m, Beam Trawl, Coll. Merrick Ekins on RV Investigator, Cruise IN2017_ V03, Sample 88–141.1 6/vi/2017. Etymology: Named after the loving memory of Anne Ekins and Anna Nelson, both of whom instructed the senior author about the beautiful design in nature. Distribution: This species is currently known only from the central coast of New South Wales, Australia, at abyssal depth. Description: Growth form: The holotype consists of the remains of a stem supporting a slightly cupped obovate (leaf-like, flabellate, fan-shaped) apical body (Figure 4 F). The body is hispid, with bundles of spicules radiating out only over a 90° quadrant. The specimen is 3 mm long x 2 mm wide. Colour: Beige on deck and beige in ethanol. Ectosomal skeleton: Thin membranous layer encrusted with abyssochelae. Endosomal skeleton: The axis of the stem consists of longitudinally arranged subtylostyles. The main body consists of radiating bundles of subtylostyles, undifferentiated from those of the stem. Megascleres: Subtylostyles are long and straight, thickest in the centre with a sharp tip (288-(504)- 1000 x 3.1- (7.4)-15.2 μm, n=49). Microscleres: Abyssochelae isochelae with obvious ridge and curved triangular shaft. (48.2-(60.6)-72.2 x 5.1- (9.7)-14.9 μm, n=45). Sigmancistras (11.6-(15.6)-18.5 x 0.9-(1.3)-1.8 μm, n=54). Molecular data: It was not possible to get unambiguous molecular data from the type material. Remarks: The shape of this species resembles one of the distal ends of the branches of A. koltuni Ereskovsky & Willenz, 2007 from the Sea of Okhotsk. However, A. annae sp. nov. lacks the large filament-forming mycalostyles that radiate from the oval bodies of A. koltuni, and also differs in lacking sigmas and having only a single size class of abyssochelae, which presents a very different shape to the isochelae of A. koltuni (Table 1). The gross morphology of this new species also superficially resembles that of the distal parts of A. hemiradiata Hestetun et al., 2017a from the SW Indian Ocean Ridge, but differs in having the slightly cupped morphology, with mainly bundles of subtylostyles radiating in one quadrant only. Abyssocladia annae sp. nov. also lacks the larger and thicker styles and the sigmas of A. hemiradiata, and has much larger sigmancistras (Table 1). Most obvious in this new species is the much larger and highly ridged abyssochelae. The only other Abyssocladia with similar chelae is A. brunni Lévi, 1964 from the Kermadec Trench. Abyssocladia annae sp. nov. differs in morphology from A. brunni which has a stem supporting a pedunculate spherical body heavily echinated by large lateral filaments up to 13 mm in length, as described both in Lévi (1964) and Koltun (1970). In addition, the current species also has smaller isochelae of a different shape (which Lévi 1964 terms ‘thaumatochetes’), sigmancistras only half the size, and smaller subtylostyles than those of A. brunni. In addition, A. brunni has styles, with only few showing slight subtylote basal swelling. The two known specimens of A. brunni described by Lévi (1964) and Koltun (1970) are possibly two different species. Abyssocladia annae sp. nov. also differs from A. natushimae Ise & Vacelet, 2010 from the Izu-Ogasawara Arc, in lacking filaments that echinate the main body, and the absence of styles, strongyles, and substrongyles and microstrongyles found in the Japanese species (Table 1).Published as part of Ekins, Merrick, Erpenbeck, Dirk & Hooper, John N.

Merrick Ekins on RV Investigator, Cruise IN2017_ V03, Sample 89-129, 6/vi/2017, growing on worm tubes. Etymology: Named for the son of the first author, Nikita Wimandi Ekins. Distribution. Central East coast and central Tasmania, Tasman Sea, Australia, at bathyal to abyssal depths. Description: Growth form: This sponge is an erect stipitate sponge with filaments radiating in all directions projecting from the cylindrical stalk (Figures 27 A, 28 C). The body is 28 mm in length and 1–2 mm in width. The filaments are 2–3 mm in length and between 50–250 µm in width, and cover approximately 80% of the upper stem. The sponge has a spherical basal region of 3 mm diameter, with protruding smaller mycalostyles (Figure 28 F). This basal holdfast region grows within a hard or consolidated substrate. Many specimens appear to be a 2 dimensional feather due to damage sustained during collection. Colour: Pale cream on deck and in ethanol. Ectosomal skeleton: The ectosomal skeleton is thin and membranous and contains the anisochelae (Figure 28 E). Endosomal skeleton: The axis of the peduncle and the filaments consist of bundles of mycalostyles longitudinally arranged (Figure 28 D). Megascleres: Large mycalostyles only occurring in the main axis (1040–1910 x 12–37 µm, n=132) (Figure 27 C–D). Smaller mycalostyles consistent throughout the sponge including the filaments and basal holdfast (209–992 x 3–19 µm, n=250) (Figure 27 E–F) (see Table 16) * Most of the specimen disappeared off the SEM stub before the measurements of the large styles, which were present, could be made. Microscleres: Palmate anisochelae with the frontal upper alae nearly fully detached from the two lateral alae, and the three lower alae nearly completely fused to each other and the fimbria, with the frontal lower alae bearing three terminal spines and each of the lateral alae with two terminal spines (9–18 µm (length) x 2–6 µm (large alae width), 3–4 µm (small alae width), n=258) (Figure 27 B) (see Table 16). Molecular data: The 28 S sequences of QM G 337197 and QM G 337534 are provided in the Sponge Barcoding Database under accession numbers SBD#2304, SBD#2305 respectively and the molecular difference to other congenerics displayed in Figure 3. Remarks: Of the 29 described species of Lycopodina six have stipitate growth form, numerous large filaments along most of the stem, an enlarged basal attachment (where known), and only simple spiculation of styles or mycalostyles as structural megascleres, and palmate anisochelae as microscleres (Table 14). Lycopodina drakensis Goodwin, Berman, Downey & Hendry, 2017, also has forceps microscleres, and the shorter mycalostyles occur in the stem and the longest ones in the filaments, the opposite of those in L. nikitawimandi sp. nov. Lycopodina lycopodium (Levinsen, 1887) and L. occidentalis (Lambe, 1893) have a similar distribution of short and long styles in the stem, body, filaments and basal attachment, but these are generally smaller than those of the new species, and both species also have forceps microscleres. Lycopodina robusta (Levinsen, 1887) has significantly smaller styles and also possesses forceps, L. tendali Hestetun et al., 2017 has larger styles that are uniformly distributed and forceps, and L. vaceleti (Van Soest & Baker, 2011) has similar mycalostyles in the stem as L. nikitawimandi sp. nov., but also has a second category of smaller styles in the filaments and body, two categories of anisochelae, one of which has a unique sigma-like shape, and forceps microscleres (Table 14).Published as part of Ekins, Merrick, Erpenbeck, Dirk & Hooper, John N.

Flowers of Fable from Northcote, Aesop, Croxall, Gellert, Dodsley, Gay, La Fontaine, Lessing, Krasicki, Herder, Merrick, Cowper, etc.
No full textThe first sentences of the preface of this little (4½ x 6¾) book set a fascinating tone: The principal object of the compiler of this collection of Fables, has been to avoid all such as contain coarse, rude, or profane expressions (iii). The same preface contains a spirited defense of long morals for short fables. This collection of 223 fables on 252 pages seems a mixtum-gatherum. There is no attempt to attribute these fables to particular authors among those mentioned on the title-page. Prose follows verse. Some fables have long applications and some none. Traditional fables are brought together with many that are new to me. I am surprised to find The Dog and the Crane (29). Here the dog acts as the wolf does in the traditional tale, but then has the same throat-problem a second time. He becomes remorseful. The crane hears of his plight and relieves him again. The dog licks her feet and asks to be her slave! The crane declares that virtue is its own reward and flies off. In another transformation, the cormorant takes fishes to a shallow pool, where he can eat them whenever he wants (9). In the traditional Bidpay fable, a crane takes them to rocks and eventually pays for his sins. Upon reflection, is the version here not the sort of fable that this editor wanted to keep out of the collection? There are also various forms of illustration, including especially rectangles, framed rectangles, initials, tailpieces. I find the emotion expressed in GGE (34) good. Also delightful is the little devil sitting at the rich sick man's ear as a philosopher lectures him about idleness (41). The illustration for MSA on 105 is full of exertion and contortion. I am surprised to see The Benefit of Recreation--Aesop at Play included, with illustration (236). The preface is signed C.K.F. William M. Whitney is stamped on the leather portion of the half-leather cover.This is a hardbound book (hard cover)C.K.F

Radar and Optical Remote Sensing of Submesoscale Frontal Features
No full textThe coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 ). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface with relatively low cost and ease of deployment. This work outlines advances in our understanding of two types of frontal features with surface expressions (nonlinear internal waves, and estuarine density fronts that develop horizontal shear instabilities) using X-band marine radar and optical remote sensing techniques. The dissertation is presented in a manuscript format, containing three first-author manuscripts and an appendix which is an additionally contributed to manuscript. The first and last chapters are an Introduction and Conclusion to the body of work.
In Chapter 2, a novel data set of X-band radar and synchronous mooring observations is presented of packets of nonlinear internal waves as they propagate and shoal from shallow waters (50 ) to shore. This work is novel in its ability to robustly characterize internal wave packet dynamics using remote sensing tools. The manuscript describes the field experiment in South-central California, presents an image processing technique for extracting cross-shore speed and angle, and details findings from combining radar with the subsurface view of the internal waves via deployed moorings. We compare radar-estimated to mooring-estimated internal wave speeds and confirm a cross-shore profile that deviates from linear theory. We additionally use the synchronous in situ data to perform a close analysis on three nearly-consecutive internal tides. We reveal inter-packet speed variability (internal wave dispersion) and an instance of internal wave polarity reversal observed in the radar and moorings.
In Chapter 3, aerial image sequences from a small Unpiloted Aircraft System (sUAS) are presented of the Connecticut River ebb plume front, which propagates into a strong tidal cross-flow. Image analysis reveals temporal and spatial scales of the instabilities, which have roughly 20 wavelengths, 2 amplitudes, and propagate near 0.4 . Additionally, the surface currents and horizontal shear across the plume front are quantified using imagery. In situ measurements from cross-front ship transects are also used to examine properties of the frontal shear zone. A non-hydrostatic numerical simulation of an ebb plume in an idealized tidal cross-flow was performed using comparable flow parameters and confirms the presence of shear instabilities, while also providing simulations of an idealized case with no tidal cross flow. We show that the results are consistent with previous theoretical work: shear instabilities are likely to emerge given the observed field and modeled conditions, and unlikely to emerge without a tidal cross-flow.
Chapter 4 additionally details the presence of horizontal shear instabilities in remote sensing observations of estuarine fronts. In this work, remote sensing observations are presented of two different estuarine flood intrusion fronts exhibiting along-front propagating horizontal shear instabilities. At Mobile Bay, AL, an X-Band radar reveals horizontal shear instabilities of O(100 ) wavelengths during maximum flood currents along a tidally-consistent flood front. James River, VA, reveals horizontal shear instabilities along a flood intrusion front with relatively similar shape and behavior, however with wavelengths O(10 ). At both sites, the shear is characterized. A relationship between observed instability wavelength and the width of the frontal shear layer is found to be consistent with instability theory. Additionally, high resolution imagery reveals intriguing evidence of instability merging at the flood intrusion tip, as well as the existence of secondary instabilities along the primary instability braid.
The appendix presents a look at a novel gravity current front on the inner shelf, which is birthed from an internal bore, and exhibits along-front propagating instabilities. This work combines concepts of frontal speed estimation detailed in Chapter 2. Additionally, we place the observed shear instabilities in the context of the gravity current flow regime in a similar manner as Chapters 3 and 4. This work is included as a relevant, secondary contribution to the aforementioned body of work
Exploratory learning for wireless networking
No full textThis dissertation highlights the importance of computer networking education and the challenges in
engaging and educating students. An exploratory learning approach is discussed with reference to
other learning models and taxonomies. It is felt that an exploratory learning approach to wireless
networks improves student engagement and perceived educational value.
In order to support exploratory learning and improve the effectiveness of computer networking
education the WiFi Virtual Laboratory (WiFiVL) has been developed. This framework enables
students to access a powerful network simulator without the barrier of learning a specialised systems
programming language. The WiFiVL has been designed to provide “anytime anywhere” access to a
self-paced or guided exploratory learning environment.
The initial framework was designed to enable users to access a network simulator using an HTML
form embedded in a web page. Users could construct a scenario wherein multiple wireless nodes were
situated. Traffic links between the nodes were also specified using the form interface. The scenario is
then translated into a portable format, a URL, and simulated using the WiFiVL framework detailed in
this dissertation. The resulting simulation is played back to the user on a web page, via a Flash
animation.
This initial approach was extended to exploit the greater potential for interaction afforded by a Rich
Internet Application (RIA), referred to as WiFiVL II.
The dissertation also details the expansion of WiFiVL into the realm of 3-dimensional, immersive,
virtual worlds. It is shown how these virtual worlds can be exploited to create an engaging and
educational virtual laboratory for wireless networks. Throughout each development the supporting
framework has been re-used and has proved capable of supporting multiple interfaces and views.
Each of the implementations described in this dissertation has been evaluated with learners in
undergraduate and postgraduate degrees at the University of St Andrews. The results validate the
efficacy of a virtual laboratory approach for supporting exploratory learning for wireless networks
Definitions of Guidelines for Introducing an Integrated Management System to Small and Medium Sized Enterprises
No full textTo survive and achieve to develop their activities in an increasingly competitive
environment, small and medium sized enterprises have to increase their
competitiveness and, progressively, reduce their operational cost. It is therefore the
objective of this research project to develop a flexible and unique management system
for these enterprises to use to integrate all management systems or activities related to
quality, safety and environmental issues and continuously improve their overall
business performance and also to get prepared for certification according to the
relevant international standards.
The research project has been based on the edition of 2000 of the ISO 9001 standard:
"Quality Management Systems
-
Requirements", the ISO 14001: 1996 standard:
"Environmental Management Systems
-
Specification with Guidance for Use", the BS
8800: 1996 standard: "Guide to Occupational Health and Safety Management
Systems" and the Business Excellence Model.
The thesis author carried out a data collection procedure to determine the special
characteristics of small and medium sized enterprises and to specify their needs for
survival and development. The results of the research reinforced the conclusions of
the relevant literature that was reviewed. The areas of literature examined related to
quality management systems as platforms for integration, to safety and environmental
management systems and to business process analysis and the conclusions were taken
under consideration from a point of view of small and medium sized enterprises.
The output of the research project is a practical guide for small and medium sized
enterprises. It is a route-map of activities for the implementation of the integrated
management system, incorporating tools addressing specific management areas using
quality, safety and environmental issues to focus them. The route-map has the
potential to integrate the overall management activities of an organization and has an
internal metric mechanism to indicate the rate of integration. The tools of the route-
map were partially implemented to two (2) SMEs, giving positive validation of the
concepts.
Musikstädte as real and imaginary soundscapes: urban musical images as literary motifs in twentieth-century German modernism
No full textPhDThis study examines German literary images of musical life as part of the wider sound identity of the modern German city at the turn of the twentieth century. Focussing on a forty-year period from 1890 to 1930, synonymous with the emergence of the modern German metropolis as an aesthetic object, the project assesses, compares and contrasts how musical life in the Musikstädte was perceived and portrayed by writers in an increasingly noisy urban environment. How does urban musical life influence and condition city writings? What are the differences and similarities between the writings on various musical cities? Can an urban textual sound identity be derived from these differences and similarities? The approach employed to answer these questions is a new, cross-disciplinary one to urban sound in literature, moving beyond reading the key sounds of the urban soundscape using urban musicology, sensorial anthropology and cultural poetics towards a literary contextualisation of the urban aural experience.
The literary motifs of the symphony, the gramophone and urban noise are put under the spotlight through the analysis of a wide range of modernist works by authors who have a special relationship with music. At the centre of this analysis are the Kaffeehausliteratur authors Hermann Bahr, Alfred Polgar and Peter Altenberg, the then Munich-based author Thomas Mann and the lesser known René Schickele. The analysis of these particular works is framed in the music-geographical context of the Musikstadt and literary underpinnings of this topos, ranging from Ingeborg Bachmann to Hans Mayer and, once again, Thomas Mann. In analysing these texts, the methodological approach devised by Strohm, who identifies the blending of a range of urban sounds as a definition of urban space and identity, is applied. His ideas combine historical literary
analysis, musical history and urban sociology. They are rarely used in the analysis of the auditory environment.Arts and Humanities Research Council
