Interfacial Microrheology of Biological Films
No full textThis thesis reports experimental studies of the rheology of biological materials, with an emphasis on interfacial layers, including protein layers and bacterial biofilms. Results are presented on layers formed by the proteins lysozyme and Staphylococcal nuclease at the air--water interface, on biofilms formed by Pseudomonas bacteria at the oil--water interface, and on the bulk rheological properties of fibrin and cystic fibrosis mucus with an eye toward its role as an interfacial barrier in the lung. The evolution of interfacial mechanical response through time is interpreted in terms of the changing microscopic structure of the layer.
The studies employ interfacial microrheology, which uses the motion of micrometer-scale particles embedded in the interface to probe the mechanical response of the surrounding material and infer its rheology. Passive measurements, which rely on thermal forces to drive the particles, are complemented by active measurements, in which ferromagnetic nanowires were rotated using magnetic fields. Additionally, the study of fibrin and cystic fibrosis mucus employs a novel technique using custom fluorescent particles that can be selectively ``switched on'' and used to characterize rheology and particle mobility over physiologically relevant time and distance scales.
This thesis also presents a software toolkit, developed as part of the thesis work to meet the demands of this research, that has found applications by other researchers in other areas.

No full textDefender: the life of Daniel H. Wells
No full textIncludes bibliographical references and index.Defender is the first and only scholarly biography of Daniel H. Wells, one of the important yet historically neglected leaders among the nineteenth-century Mormons—leaders like Heber C. Kimball, George Q. Cannon, and Jedediah M. Grant. An adult convert to the Mormon faith during the Mormons’ Nauvoo period, Wells developed relationships with men at the highest levels of the church hierarchy, emigrated to Utah with the Mormon pioneers, and served in a series of influential posts in both church and state. Wells was known especially as a military leader in both Nauvoo and Utah—he led the territorial militia in four Indian conflicts and a confrontation with the US Army (the Utah War). But he was also the territorial attorney general and obtained title to all the land in Salt Lake City from the federal government during his tenure as the mayor of Salt Lake City. He was Second Counselor to Brigham Young in the LDS Church's First Presidency and twice served as president of the Mormon European mission. Among these and other accomplishments, he ran businesses in lumbering, coal mining, manufacturing, and gas production; developed roads, ferries, railroads, and public buildings; and presided over a family of seven wives and thirty-seven children. Wells witnessed and influenced a wide range of consequential events that shaped the culture, politics, and society of Utah in the latter half of the nineteenth century. Using research from relevant collections, sources in public records, references to Wells in the Joseph Smith papers, other contemporaneous journals and letters, and the writings of Brigham Young, Quentin Thomas Wells has created a serious and significant contribution to Mormon history scholarship.--Provided by publisher.1634-1814, a Puritan family's progress: the Wells' migration from England to America -- 1814-1838, Daniel H.

Barsine obsoleta Reich 1937, comb. n.
No full textBarsine obsoleta (Reich, 1937), comb. n. (Figs. 5–6, 19, 27) Miltochrista gratiosa f. obsoleta Reich, 1937, Deutsche Entomologische Zeitschrift Iris 51: 120 (Type locality: [China, Zhejiang] “West Tien-mu-shan”). Type material examined. Neotype (Figs. 5, 19), designated herein for Miltochrista gratiosa f. obsoleta Reich, 1937: ♂, whitish printed label "West Tien-mu-shan, Prov. Chekiang [Zhejiang], 29.V.1932, H. Höne " / dark pink handwritten label " ♂ Type Mil. [ochrista] gratiosa ssp. obsoleta Reich I. Gen. " / greyish printed label with a sign " ♂ ", slide AV 1834m Volynkin (Coll. ZFMK). Other material examined: 13 ♂, 1 ♀, [China, Zhejiang] West Tien-mu-shan, Prov. Chekiang, H. Höne, 9.V., 15.V., 16.V., 24.V., 25.V., 26.V., 29.V., 2.VI., 4.VI., 9.VI.1932, slide AV1835f Volynkin (♀) (Coll. ZFMK); 3 ♂, 1 ♀, [China, Zhejiang] Ost Tien-mu-shan, Prov. Chekiang, H. Höne, 7.V., 2.VI., 11.vi., 13.VI.1931 (Coll. ZFMK); 1 ♀, [China, Zhejiang] Mokanshan, Prov. Chekiang, H. Höne, 9.V. [19]19 (Coll. ZFMK); 1 ♀, [China, Zhejiang] Ost Tien-mu-shan, Prov. Chekiang, Höne, 18.VI.1931 (Coll. ZFMK); 1 ♀, [China, Zhejiang] Ost Tien-mu-shan, Prov. Chekiang, H. Höne, 1.VI.1931 (Coll. ZFMK); 2 ♂, [China, Zhejiang] West Tien-Mu-Shan (1600 m), Pz. Chekiang, H. Höne, 2.VI., 6.VI.1932 (Coll. ZFMK). Note. One male specimen in coll. ZFMK from West Tien-mu-shan, 29.V.1932 (Fig. 5) is labelled as a " Type ", and series of both sexes from the same locality and "Ost Tien-mu-shan" are labeled as " paratypes ". Nevertheless, in the original description, Reich (1937) mentioned only one female specimen with the label " West Tien-mu-shan, 10.VI. " which must be treated as holotype by monotypy. Thus, the "type" male is not a type in fact, as well as all other "paratype" specimens because there are no any specimens in ZFMK collection from West Tien-mu-shan with a date 10.VI. Daniel (1951) mentioned the existence of this specimen in materials examined by Reich, but without any mention of collection. In ZFMK collection there is a female specimen with a label handwritten by F. Daniel "Reich hat nach diesem Stück ssp. obsoleta beschrieben. Es stellt die ♀- Type der gen. vern. clar", but this specimen has the date 4.VI.1932, and therefore cannot be the holotype. In addition, there is no specimen of B. obsoleta having the label mentioned in Zoological Museum of Tel-Aviv University (TAU, Israel) where the Reich's collection is deposited at present (V.D. Kravchenko, pers. comm.), as well as in the collection of Naturkunde Museum (NKMB, Berlin, Germany) where some specimens from the Reich's collection are also deposited (W. Mey, pers. comm.), therefore we can conclude that the holotype is lost. At the same time, many Barsine species have similar external appearance, and to avoid probable confusion and for the nomenclature stabilization the neotype designation is necessary. As the neotype we designate the male specimen in ZFMK collection labeled as " Type " (Figs. 5, 19). Diagnosis. Externally (Figs. 5–6), the species differs clearly from two other relatives (Figs. 7–12) by its pale yellow ground color and significantly reduced blackish pattern elements. The male genitalia (Fig. 19) is closer to that of B. callorufa (Figs. 20–21), but the uncus is broader, the valvae is slightly broader, the medial costal process is longer, the basal saccular process is narrower distally, the 1st medial diverticulum with weaker scobination, the main lobe of the 2nd medial diverticulum is smaller and covered with much weaker cornuti, the 5th medial diverticulum is smaller, and the 3rd medial diverticulum is slightly longer. The female genitalia (Fig. 27) differ from B. callorufa (Fig. 28), by the much more rugose antrum, and the somewhat longer and posteriorly narrower ductus bursae. Differences from B. fossi are listed in the diagnosis of the latter. Distribution. Eastern China (Zhejiang, Jiangxi, Hubei, Fujian) (Reich 1937; Fang 2000). The record for Nepal (Daniel 1961) is doubtful.Published as part of Volynkin, Anton V. & Černý, Karel, 2017, A review of the Barsine obsoleta species-group with description of a new species from Vietnam (Lepidoptera, Erebidae, Arctiinae), pp. 188-200 in Zootaxa 4254 (2) on pages 189-193, DOI: 10.11646/zootaxa.4254.2.2, http://zenodo.org/record/54586
Ethnic identity, political identity and ethnic conflict: simulating the effect of congruence between the two identities on ethnic violence and conflict
No full textThis thesis outlines and presents an alternative hypothetical process to the emergence of ethnic conflict. Ethnic conflicts, rather than being dependent upon pre-existing 'ancient hatreds', are instead the result of a congruence between ethnic and political identity which grants individuals the ability to use ethnicity to identify and eliminate political threats. This hypothesis is formed by the examination of three case studies of ethnic conflict: Lebanon, Northern Ireland and Croatia. This hypothesis is then formalised and tested using an agent based simulation in which agent interactions are dependent upon ethnic and political identity and the congruence between the two. As predicted there was a strong positive correlation between how accurately ethnic identity reflected political identity and the level of ethnically motivated violence in the simulation, although the relationship was not linear. Furthermore the effect of a shift in congruence was found to be roughly comparable to the effect of initialising agents with a moderate level of pre-existing ethnic antagonism

Competing models of socially constructed economic man : differentiating Defoe's Crusoe from the Robinson of neoclassical economics
No full textDaniel Defoe’s Robinson Crusoe has seldom been read as an explicitly political text. When it has, it appears that the central character was designed to warn the early eighteenth-century reader against political challenges to the existing economic order. Insofar as Defoe’s Crusoe stands for "economic man", he is a reflection of historically-produced assumptions about the need for social conformity, not the embodiment of any genuinely essential economic characteristics. This insight is used to compare Defoe’s conception of economic man with that of the neoclassical Robinson Crusoe economy. On the most important of the ostensibly generic principles espoused by neoclassical theorists, their "Robinson" has no parallels with Defoe’s Crusoe. Despite the shared name, two quite distinct social constructions serve two equally distinct pedagogical purposes. Defoe’s Crusoe extols the virtues of passive middle-class sobriety for effective social organisation; the neoclassical Robinson champions the establishment of markets for the sake of productive efficiency
Naming in OHP
No full textNaming is a key issue in any distributed system. In particular, with the Open Hypermedia Systems Working Group's efforts towards openness and interoperability in Open Hypermedia Systems (OHS) resulting in the need for (globally) valid names for all types of resources the issue of naming has become increasingly important. In this position paper we examine the issues involved in naming and a naming proposal to be used within the Open Hypermedia Protocol (OHP)
Deliver us from Evil: The Effects of Mortality Salience and Reminders of 9/11 on Support for President George W. Bush
No full textAccording to terror management theory, heightened concerns about mortality should intensify the appeal of charismatic leaders. To assess this idea, we investigated how thoughts about death and the 9/11 terrorist attacks influence Americans’ attitudes toward current U.S. President George W. Bush. Study 1 found that reminding people of their own mortality (mortality salience) increased support for Bush and his counterterrorism policies. Study 2 demonstrated that subliminal exposure to 9/11-related stimuli brought death-related thoughts closer to consciousness. Study 3 showed that reminders of both mortality and 9/11 increased support for Bush. In Study 4, mortality salience led participants to become more favorable toward Bush and voting for him in the upcoming election but less favorable toward Presidential candidate John Kerry and voting for him. Discussion focused on the role of terror management processes in allegiance to charismatic leaders and political decision making.This is an electronic version of the article published in Personality and Social Psychology Bulletin, 30(9):1136-1150, 2004 Sept.
