Newbigging Pottery Musselburgh, Scotland c 1800 - c 1930 Ceramic Resource Disc 1
No full textThe Newbigging ceramic material, listed and photographed on the enclosed disk has been assigned to the National Museums of Scotland and was catalogued using accession numbers (FD 2004.1.1 to 507. This small and fairly commonplace ceramic assemblage derives from a pottery of 19th and early 20th century date. The shards have been divided by fabric type, form and decoration into 6 folders and 58 files. The majority of the pottery was recovered during a small rescue excavation and salvage operation funded by Historic Scotland. Most of the on site work was carried out by Alison McIntyre, Alan Radley and the author over a three week period at the end of December 1987 and beginning of January 198
Molyneux’s question and the phenomenology of shape
No full textWilliam Molyneux raised the following question: if a congenital blind person is
made to see, and is visually presented with a cube and a globe, would he be able to
call the shapes before him a cube and a globe before touching them? Locke,
Berkeley, Leibniz, and Reid presented their phenomenological view of shape
perception, i.e. their view as to what it is like to perceive shape by sight and touch, in
responding to Molyneux’s Question. The four philosophers shared the view that
visual perception delivers no solid shape. This view would provide a premise for an
argument for immaterial objects. The purpose of my thesis is to reject that argument.
Kant’s view and John Campbell’s externalist account offer a way to reject the
premise of the argument in question. However, my strategy is not to adopt their view.
I pursue Reichenbach’s view that the there is no congruence or incongruence
involved in the visual phenomenology. I develop his view, and propose the view that
visual perception delivers no flat or solid shape. Although my view endorses the
premise in question, I can offer a way to reject the argument. This is because my
view is compatible with a form of externalism about perception (which differs from
Campbell’s). My view can also do full justice to the phenomenological views
presented by the four philosophers
Soft biometrics for surveillance: an overview
No full textBiometrics is the science of automatically recognizing people based on physical or behavioral characteristics such as face, fingerprint, iris, hand, voice, gait and signature. More recently, the use of soft biometric traits has been proposed to improve the performance of traditional biometric systems and allow identification based on human descriptions. Soft biometric traits include characteristics such as height, weight, body geometry, scars, marks and tattoos (SMT), gender, etc. These traits offer several advantages over traditional biometric techniques. Soft biometric traits can be typically described using human understandable labels and measurements, allowing for retrieval and recognition solely based on verbal descriptions. Unlike many primary biometric traits, soft biometrics can be obtained at a distance without subject cooperation and from low quality video footage, making them ideal for use in surveillance applications. This chapter will introduce the current state-of-the-art in the emerging field of soft biometric
Comparing diagnoses from expert systems and human experts
No full textThis paper discusses a comparison of one heuristic and two Bayesian belief network based expert systems used to aid veterinarians in the process of differential diagnoses of equine diseases where coughing is the presenting clinical sign. Each implementation infers the likelihood of the presence of a number of diseases based on information on the presence or absence of certain clinical signs. The Bayesian belief network approaches are similar except that one includes the use of prior information in the form of disease prevalence estimates. Both are implemented using the Hugin software package. The three approaches were compared using test cases and the lists of resulting diagnoses were examined for agreement using a measure of concordance. The results indicated a difference between the heuristic approach which used the rule-based scoring mechanism and the Bayesian systems. There was, however, little difference between the diagnoses produced by the two Bayesian implementations, indicating that the incorporation of prevalence data makes little difference in diagnostic systems of this type. The findings were also compared with those of clinical experts. The analysis indicated that clinicians were not always in agreement. Moreover, using the same set of test cases the experts were more in agreement with the Bayesian approaches than with the heuristic approach
Exploring the promises of intersectionality for advancing women's health research
No full textAbstract Women's health research strives to make change. It seeks to produce knowledge that promotes action on the variety of factors that affect women's lives and their health. As part of this general movement, important strides have been made to raise awareness of the health effects of sex and gender. The resultant base of knowledge has been used to inform health research, policy, and practice. Increasingly, however, the need to pay better attention to the inequities among women that are caused by racism, colonialism, ethnocentrism, heterosexism, and able-bodism, is confronting feminist health researchers and activists. Researchers are seeking new conceptual frameworks that can transform the design of research to produce knowledge that captures how systems of discrimination or subordination overlap and "articulate" with one another. An emerging paradigm for women's health research is intersectionality. Intersectionality places an explicit focus on differences among groups and seeks to illuminate various interacting social factors that affect human lives, including social locations, health status, and quality of life. This paper will draw on recently emerging intersectionality research in the Canadian women's health context in order to explore the promises and practical challenges of the processes involved in applying an intersectionality paradigm. We begin with a brief overview of why the need for an intersectionality approach has emerged within the context of women's health research and introduce current thinking about how intersectionality can inform and transform health research more broadly. We then highlight novel Canadian research that is grappling with the challenges in addressing issues of difference and diversity. In the analysis of these examples, we focus on a largely uninvestigated aspect of intersectionality research - the challenges involved in the process of initiating and developing such projects and, in particular, the meaning and significance of social locations for researchers and participants who utilize an intersectionality approach. The examples highlighted in the paper represent important shifts in the health field, demonstrating the potential of intersectionality for examining the social context of women's lives, as well as developing methods which elucidate power, create new knowledge, and have the potential to inform appropriate action to bring about positive social change.</p

Effects of mesquite control and mulching treatments on herbaceous productivity and soil properties
No full textThe objective of this study was to evaluate the effects of mesquite overstory removal and modifications of soil properties due to mulching treatments on herbaceous production. The three overstory treatments were complete removal of mesquite overstory with no removal of regrowth, complete removal of mesquite overstory with removal of regrowth and an untreated control. The mulching treatments included applications of chip mulch, commercial compost, lopped-and-scattered mesquite branchwood and a control. Both overstory treatments resulted in an increase of over 20% in total annual herbaceous production. The overstory treatment of complete removal of mesquite overstory with no removal of regrowth had the greatest impact on fall production of native herbaceous species during years of relatively high precipitation, at times increasing production by almost 2-fold. Mulching treatments had no effect on herbaceous production; however, soil pH and plant available phosphorus was affected by some of the mulching treatments

Bird abundance as an indicator of habitat quality for breeding birds
No full textReproductive success and survival of birds often are impractical to measure. Therefore, biologists frequently rely on measures of bird abundance alone to evaluate habitat quality for breeding birds. I examined whether results from standard survey techniques for birds during the breeding season reflected number of nesting pairs and reproductive success of 5 passerine species. Abundance of 3 species was positively associated with number of nesting pairs, but the relationship between abundance and reproductive success varied among these species. Differences in detectability of breeding males may partly explain why abundance and number of nesting pairs were related in some species and not in others. Variations in the availability and quality of habitat patches among plots could produce the different relationships I observed between abundance and reproductive success. My results suggest that measures of reproductive success as well as abundance should be used to determine habitat quality for breeding birds
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
