• A.I. Techniques for Modelling Anger in Emotional Agents

      Slater, Stuart; Moreton, Robert; Buckley, Kevan (University of Wolverhampton, School of Computing and Information Technology, 2008)
      The research presented here, attempts to review a range of techniques commonly categorized under the umbrella of artificial intelligence (A.I.) that could be applied when developing agents with emotions in a range of applications. The paper focuses on anger (and its related emotions), an emotion strongly linked with aggression which of course forms the basis of many computer games where killing or attacking other players or in-game agents is often central to the game’s purpose. The paper begins with a psychology focused review of anger and its related emotions, before presenting techniques to encode some of these elements using Finite State Machines and Fuzzy Logic.

    • Adjusting bone mass for differences in projected bone area and other confounding variables: an allometric perspective.

      Nevill, Alan M.; Holder, Roger L. (American Society for Bone and Mineral Research, 2007-01-25)
      The traditional method of assessing bone mineral density (BMD; given by bone mineral content [BMC] divided by projected bone area [Ap], BMD = BMC/Ap) has come under strong criticism by various authors. Their criticism being that the projected bone "area" (Ap) will systematically underestimate the skeletal bone "volume" of taller subjects. To reduce the confounding effects of bone size, an alternative ratio has been proposed called bone mineral apparent density [BMAD = BMC/(Ap)3/2]. However, bone size is not the only confounding variable associated with BMC. Others include age, sex, body size, and maturation. To assess the dimensional relationship between BMC and projected bone area, independent of other confounding variables, we proposed and fitted a proportional allometric model to the BMC data of the L2-L4 vertebrae from a previously published study. The projected bone area exponents were greater than unity for both boys (1.43) and girls (1.02), but only the boy's fitted exponent was not different from that predicted by geometric similarity (1.5). Based on these exponents, it is not clear whether bone mass acquisition increases in proportion to the projected bone area (Ap) or an estimate of projected bone volume (Ap)3/2. However, by adopting the proposed methods, the analysis will automatically adjust BMC for differences in projected bone size and other confounding variables for the particular population being studied. Hence, the necessity to speculate as to the theoretical value of the exponent of Ap, although interesting, becomes redundant.
    • Aggregation in temporal databases

      Kline, Rodger Nickels; Kline, Rodger Nickels (The University of Arizona.The University of Arizona., 19991999)
      Temporal database systems extend relational database systems to support time-varying information. One important such extension is support for time-varying aggregate functions, such as a time-varying average. Our research will show that temporal aggregates may be specified in a semantically well defined manner yet be efficiently implemented as simple extensions to relational databases. We introduce a taxonomy of temporal aggregation, based on a study of all major temporal query languages containing aggregates. The taxonomy categorizes the expressiveness and functionality of temporal aggregation. Based on this taxonomy, we introduce extensions to TSQL2 for temporal aggregation. The proposed language constructs allow one to express the variety of features identified in the taxonomy. We briefly discuss the semantics for the temporal aggregate language extension. We introduce an operator for evaluating temporal aggregates in a temporal relational algebra; the operator was designed to implement the tuple semantics. We show that theoretically, the most efficient evaluation of a temporal aggregate over a relation with n unique timestamps requires Θ(n log n) time, with O(n log n) space in any decision tree algorithm. We provide an example algorithm meeting these requirements, utilizing a 2-3 tree. Based on the requirements for evaluation of the algebraic operator, we introduce a series of main memory algorithms for evaluating temporal aggregates, including the aggregation tree, k-ordered aggregation tree, the chalkboard algorithm, the linked-list algorithm, and show how to perform aggregation using a 2-3 tree. The algorithms exhibit different applicability depending on aspects of the input relation, including sort order, percentage of long-lived tuples, and number of tuples. We also provide an algorithm which executes using only a user-limited amount of memory, the paging aggregation tree. We characterize the effectiveness of these algorithms based on an empirical study of their performance.
    • Antifungal Compounds Produced in Antagonistic Competition Between Marine Fungi

      Tariq, Muhammad Buchan (The University of Arizona., 2012)
      Competition among fungi has been characteristic of antibiotic relationships between microbes, leading to the discovery of novel antimicrobial compounds. This study observed such antagonistic relationships between marine fungi isolated from coral off the coast of Woods Hole, Massachusetts. Competition assays were conducted on these fungal isolates against two chosen competing species on PDA plates. Three fungal isolates were observed to release antifungal compounds inhibiting the growth of the competing species. Methanol extracts were taken from each of the three fungal isolates and ¹H and ¹³C NMR spectra obtained. The three fungi were shown to produce antifungal compounds, not observed in previous studies. 14 fractions were obtained from subjecting the methanol extracts from each of the three fungi to chromatography. The final step remains to test these fractions for antifungal activity leading to the isolation and identification of the antifungal compounds.

    • Ballard's Story of O: ‘The Voices of Time’ and the Quest for (Non)Identity

      Wymer, Rowland; Anglia Ruskin University (Palgrave Macmillan, 2012-01)
      The Voices of Time’ is the key work from Ballard’s early period, prefiguring the tone and narrative direction of the ‘disaster’ novels and eloquently articulating one of his lifelong preoccupations – the search for identity in a changing environment. At one level the story is a poetic meditation on time and death, an evocation of change and degeneration on a cosmic scale which recalls such works as Spenser’s ‘Mutabilitie Cantos’ or Donne’s ‘The First Anniversary’. Like Donne, Ballard employs up-to-the-minute scientific rhetoric to reinvigorate and revalidate a very traditional lament about the inevitability of decay. Such a lament is also present both in ‘classic’ science fiction texts such as The Time Machine or John W. Campbell’s ‘Twilight’ and in important ‘New Wave’ stories like M. John Harrison’s ‘Running Down’ or Pamela Zoline’s ‘The Heat Death of the Universe’. However, Ballard’s handling of this theme acquires some of its uniqueness from the fact that he was strongly interested in the ideas of both Freud and Jung. Consequently, the protagonist’s quest for identity within the ceaseless flow of time can be read with equal ease as a successful process of Jungian individuation or as a disastrous surrender to the Freudian death drive. At the heart of the story is what Rosemary Jackson has called the ‘goal which lies behind all fantastic art . . . the arrival at a point of absolute unity of self and other, subject and object, at a zero point of entropy’. Whether this ‘zero point’ represents a completion of self or a loss of self, whether the ‘O’ is full or empty, becomes impossible to say, as is also the case with Pauline Reage’s erotic classic The Story of O, which Ballard greatly admired.
    • Becoming an eportfolio teacher.

      Hughes, Julie (Washington, DC: Stylus Publishing, 2009)
      This book: Higher education institutions of all kinds - across the United States and around the world - have rapidly expanded the use of electronic portfolios in a broad range of applications including general education, the major, personal planning, freshman learning communities, advising, assessing, and career planning. Widespread use creates an urgent need to evaluate the implementation and impact of e-portfolios. Using qualitative and quantitative methods, the contributors to this book—all of whom have been engaged with the Inter/National Coalition for Electronic Portfolio Research—have undertaken research on how e-portfolios influence learning and the learning environment for students, faculty members, and institutions. This book features emergent results of studies from 20 institutions that have examined effects on student reflection, integrative learning, establishing identity, organizational learning, and designs for learning supported by technology. It also describes how institutions have responded to multiple challenges in e-portfolio development, from engaging faculty to going to scale. These studies exemplify how e-portfolios can spark disciplinary identity, increase retention, address accountability, improve writing, and contribute to accreditation. The chapters demonstrate the applications of e-portfolios at community colleges, small private colleges, comprehensive universities, research universities, and a state system.
    • Blogging for beginners? Using blogs and eportfolios in Teacher Education.

      Hughes, Julie; Purnell, Emma (Lancaster: Lancaster University, Department of Educational Research, 2008)
      This paper explores the use of an eportfolio and an educational blog within, and beyond, a professional pre-service teacher education programme, the Post-Graduate Certificate in Education (PGCE) for the post-compulsory sector. Writing within dialogic storytelling practices in an online environment allows student teacher development and identity to be seen “as a gradual ‘coming to know’” (Winter, 2003, p.120) dependent upon connections and interactions with others through both text and non-text formats such as metaphor, music and video. The authors explore their personal experiences as teacher (Julie) and learner (Emma) and eportfolio’s potential for longer term impact on and in their professional teaching lives.
    • Bovine enterovirus as an oncolytic virus: foetal calf serum facilitates its infection of human cells.

      Smyth, M; Symonds, A; Brazinova, S; Martin, J; Molecular Structure Solutions, MA Block, Wolverhampton, UK. (2002-07)
      Many viruses have been investigated for their oncolytic properties and potential use as therapeutic agents for cancer treatment. Most of these replication-competent viruses are human pathogens. We investigated the oncolytic properties of an animal virus which is non pathogenic for both its natural host and humans. Bovine enterovirus has previously been shown to exhibit a very wide tissue tropism for cell types in vitro. We compare the ability of bovine enterovirus to replicate in and to cause cytopathic effect in freshly isolated human monocytes and monocyte derived macrophages with the monocyte-like U937 tumour cell line. We also include the adherent ZR-75-1 human breast cancer cell line. We have also carried out infections of bovine enterovirus in the presence and in the absence of serum of bovine origin. Our study shows that the virus will replicate in and produce cytopathic effect in the U937 and ZR-75-1 cell types to the same extent as the cells (BHK-21) in which the virus is routinely propagated. We believe bovine enterovirus to be a worthwhile candidate for further study as an anti-tumour agent.
