Periodicities in the high-mass X-ray binary system RXJ0146.9+6121/LSI+61 235
No full textThe high-mass X-ray binary RX J0146.9+6121, with optical counterpart LS I+61°235 (V831 Cas), is an intriguing system on the outskirts of the open cluster NGC 663. It contains the slowest Be type X-ray pulsar known with a pulse period of around 1400 s and, primarily from the study of variation in the emission line profile of Hα, it is known to have a Be decretion disc with a one-armed density wave period of approximately 1240 d. Here we present the results of an extensive photometric campaign, supplemented with optical spectroscopy, aimed at measuring short time-scale periodicities. We find three significant periodicities in the photometric data at, in order of statistical significance, 0.34, 0.67 and 0.10 d. We give arguments to support the interpretation that the 0.34 and 0.10 d periods could be due to stellar oscillations of the B-type primary star and that the 0.67 d period is the spin period of the Be star with a spin axis inclination of 23+10−8 degrees. We measured a systemic velocity of −37.0 ± 4.3 km s−1 confirming that LS I+61°235 has a high probability of membership in the young cluster NGC 663 from which the system's age can be estimated as 20–25 Myr. From archival RXTE All Sky Monitor (ASM) data we further find ‘super’ X-ray outbursts roughly every 450 d. If these super outbursts are caused by the alignment of the compact star with the one-armed decretion disc enhancement, then the orbital period is approximately 330 d
Developing a fleet scheduling model for a combination carrier using both full-freighters and passenger aircraft under a demand disruption
No full textSince the first cargo flight in 1910 (Morrell [42]), air cargo has proven to be of great value to society. With over US $6 trillion worth of goods being transported through air cargo, accounting for around 35% of all global trade measured by value (Boeing [15]), it is impossible to deny its significance in today’s world. Air cargo provides us with a fast, reliable and safe method of transporting goods, making it attractive to industries where short shipping times are of the essence. Generally, there are two conventional ways of transporting air cargo – through the use of full-freighter aircraft and through the use of the belly space under the main cabin on passenger aircraft...Aerospace Engineerin

Oriental enlightenment: the problematic military experiences and cultural claims of Count Maurice Auguste comte de Benyowsky in Formosa during 1771
No full textMaurice Benyowsky's colourful version of his global adventures during the heady, expansive days of the late-Enlightenment remains still as an historical account, and is perhaps destined for reification at a time of romantic, postmodernist cultural affirmation. Yet this paper argues that within it there lies a virile and possibly dangerous Orientalism, one at least partially based upon a lurid, opportunistic and self-seeking fabrication of his visit to Taiwan (Formosa) in the year 1771. This paper examines the veracity, provenance and historiography of the Benyowsky account of late-eighteenth century Formosa, both as an exercise in one facet of Taiwanese history and as some exploration of the origin and maintenance of European views of the "other" and of the "orient" as they were transforming during the late-Enlightenment period. Furthermore a principal task is to provide an historiographical analysis that illustrates both the initial reasons for the acceptance of Benyowsky's lurid account as well as the wider contexts of its long life as a seemingly reliable and authentic tale. Questions remain as to the cultural contexts of any general acceptance of otherwise doubtful stories, experiments, claims and "adventures". Here there is little doubt that the original Memoirs were given greater credence by Benyowsky's talent in self-fashioning his character and status as those of a reliable gentleman
Council cottages and community in inter-war Britain: a study of class, culture,politics and place.
No full textPhDThis thesis makes a contribution to the debates surrounding the idea of community
on the cottage council estates of inter-war Britain. It questions the conventional
wisdom that community was lacking upon these estates. Recognising the
problematic nature of the notion of community, this thesis overcomes the confusion
inherent in the term when it is used to describe social structures by viewing
community instead as a structure of meaning, as a discursive rather than material
reality. This guides my examination of community on the estates. Rather than
there being no community, it is argued that there were at least three different
discourses of community, and what is important is the relationships between them.
Chapter One discusses the contexts in which these estates were built, and then sets
out the ways in which community is understood in this thesis. Chapter Two
explains the methodology that was used, a combination of archival and oral histoiy.
In Chapter Three Roehampton and Watling - the two estates this research focuses
upon - are described in order to provide the contextual setting for my interpretation
of the discourses of community that were present there. Chapter Four is concerned
with community from the viewpoint of the residents who lived on the estates.
Chapter Five considers discourses of community from the point of view of the
tenants' and residents' associations that developed upon Roehampton and Watling.
Chapter Six explores the discourse of community that was promoted on the estates
by the Community Association movement.
Overall the thesis argues that the discourses of community on inter-war
housing estates have to be understood in terms of the occupational structures,
cultures and politics of these estates
Global subjective memorability and the strength-based mirror effect
No full textBetween-list manipulations of memory strength through repetition commonly generate a mirror effect, with more hits, and fewer false alarms for strengthened items. However, this pattern is rarely seen with within-list manipulations of strength. Three experiments investigated the conditions under which a within-list mirror effect of strength (items presented once or thrice) is observed. In Experiments 1 and 2, we indirectly manipulated the overall subjective memorability of the studied lists by varying the proportion of non-words. A within-list mirror effect was observed only in Experiment 2, where a higher proportion of non-words was presented in the study list. In Experiment 3, the presentation duration for each item (0.5 s versus 3 s) was manipulated between groups with the purpose of affecting subjective memorability: A within-list mirror effect was observed only for the short-presentation durations. Thus, across three experiments, we found the within-list mirror effect only under conditions of poor overall subjective memorability. We propose that when the overall subjective memorability is low, people switch their response strategy on an item-by-item basis, and that this generates the observed mirror effect. <br/
Student perceptions of their autonomy at University
No full text© 2017, The Author(s). Learner autonomy is a primary learning outcome of Higher Education in many countries. However, empirical evaluation of how student autonomy progresses during undergraduate degrees is limited. We surveyed a total of 636 students’ self-perceived autonomy during a period of two academic years using the Autonomous Learning Scale. Our analysis suggests that students do not perceive themselves as being any more autonomous as they progress through University. Given the relativity of self-perception metrics, we suggest that our results evince a “red queen” effect. In essence, as course expectations increase with each year, each student’s self-perceived autonomy relative to their ideal remains constant; we term this the “moving goalpost” hypothesis. This article corroborates pedagogical literature suggesting that providing students with opportunities to act autonomously and develop confidence is key to developing graduates who have the independence that they need in order to be successful in the workplace
Challenging Male Hegemony: A Case History of Women's Experiences in British and US Higher Education, 1970-2002
No full textThis thesis is located within the discipline of history, and centres around the
experiences of women in US and British universities. Higher education in both the US and
the UK, as throughout the world, has historically been male-led and male-controlled. This
male hegemony of higher education continues to the present, as evidenced by the low
percentage of women in the upper echelons of academia (for example, professors).
Women in the US and the UK have been challenging this male hegemony since their
admittance to higher education institutions in the nineteenth century. They faced fierce
opposition in their efforts to open higher education to women. This opposition was later
echoed in the resistance to twentieth-century feminists' efforts to found women's studies
programmes.
The male hegemony of higher education is evident in the case histories of the
experiences of women at Appalachian State University (ASU) and the University of
Gloucestershire (UG) in the latter part of the twentieth century. ASU and UG, although
located in different countries, have similarities which make a comparison interesting. The
male hegemony of the institutions, and women's challenges to it, is especially illustrated
when analysing three areas: residence hall life (living), staff issues (working), and the
women's studies programmes (teaching and learning).
Women students at both institutions experienced, and successfully challenged,
strict residence rules through the 1960s. National influences, such as the change in the age
of majority, and pressure from the students themselves brought a loosening of these rules
in the 1970s and 1980s. The conservative nature of the institutions also influenced the
experience of women academic staff. Institutional management was not proactive
regarding women's issues, and there is strong evidence of a `glass ceiling' at both
institutions. The male hegemony of the institutions was also illustrated in the struggle to
found and maintain women's studies programmes

CAVITY RINGDOWN DETECTION OF -HOBuO RADICAL FORMED FROM n-BUTOXY RADICAL ISOMERIZATION
No full textAuthor Institution: Chemistry Dept., California Institute of Technology; Jet Propulsion Laboratory, California Institute of TechnologyAlkoxy radicals are important intermediates in the oxidation of alkanes leading to tropospheric air pollution. One of the key reaction pathways for long chain alkoxy radical loss is by isomerization through a six member transition state to form a hydroxy-alkyl radical. We report the first detection of the hydroxyl radical intermediate from the isomerization of the n-butoxy radical in the region at low resolution by IR cavity ringdown spectroscopy. Observation of the OH stretch band has allowed us to measure the kinetics of its formation in a high pressure laser photolysis cell
