Subjects: subject: Engineering, Electronics and Electrical.

description: In this work we investigate rateless coding and modulation for wireless communication systems. In particular we are interested in channels in which only the transmitter has channel knowledge. For this setting, we show that rateless codes have properties that make them well suited for wireless systems. We advance the theory of rateless codes by proving the existence of rateless codes which are "good" for all possible realizations of fading channels simultaneously. To complement rateless coding, we introduce a novel modulation scheme called mu-PAM modulation. We show that typical M-ary modulation schemes are not always well suited for the channels considered in this work, and that mu-PAM modulation has benefits relative to standard M-ary PAM. A simple demodulation scheme is presented and its performance is analyzed and simulated. Applications using rateless codes over wireless channels are considered. We examine the behavior of a streaming application with delay constraints over fading channels, comparing rateless codes with other traditional systems. Benefits of the rateless approach are presented, and theoretical guarantees on probability of outage are developed. Finally, the use of rateless codes for relay networks are explored and we demonstrate theoretic limits on the rate of communication for the proposed relaying strategy. Simulations validate the performance of the strategy.

description: Background: To assess reasons for continuing practice variation in the management of childhood nephrotic syndrome despite expert reviews and guidelines, we are conducting a longitudinal cohort study in children with glucocorticoid sensitive nephrotic syndrome. Objectives of this mid-study report are to describe patient and physician recruitment characteristics, glucocorticoid prescriptions, use of second line agents, biopsy practices, and adherence to study protocol. Methods: Children with new onset nephrotic syndrome and providers are being recruited from all 12 pediatric nephrology centres across Canada with > 2½ years follow-up. Data collection points of observation are over a minimum 36 months. Details of prescribed glucocorticoids and of all second line agents used during treatment are being collected. All relapses are being recorded with time to urinary remission of proteinuria. Results: To date, 243 patients (57.1% male) from 12 centres were included. Median number of patients per centre was 29 (range 2–45), and median age of cohort was 7.3 (IQR 4.2) at enrollment. Forty-eight physicians were recruited, median 5 (range 2–8) per site. Median number of relapses per patient year of follow-up was 2.1 (IQR 4). Cumulative dose variability of glucocorticoids prescribed per episode of proteinuria and length of treatment was observed between participating centres. Conclusion: The Canadian pediatric nephrology community established a longitudinal childhood nephrotic syndrome cohort study that confirms ongoing practice variability. The study will help to evaluate its impact on patient outcomes, and facilitate clinical trial implementation in nephrotic syndrome.

Subjects: subject: Education, Tests and Measurements.

description: This exploratory research compares Q-matrices related to two multiple choice tests in mathematics. These Q-matrices are elaborated in three different conditions. In the first one, only the items are available. In the second one, the items are presented as set together with a factor analysis. In the third condition, the item difficulty and discrimination parameters are provided to the experts as well as the distractors' analysis results. The cognitive model RUM (Reparametrized Unified Model) is used to compare the cognitive structure of the different matrices related to the same test. The form of the matrices, the agreement between the experts and the parameters estimated with the RUM are compared. The results tend to show that condition 2 cognitive structure is stronger for both tests. The difference with conditions 1 or 3 is, however, not very large. The third condition leads the experts to pay attention to non relevant aspects of the answering process and leads to the worst quality matrices.

Nonparametric tests of hypotheses for umbrella alternatives
Creators: name: Brion, Vladislav
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Mathematics.

description: A general method for nonparametric hypothesis testing for umbrella alternatives is proposed. Such alternatives arise in situations where the treatment effect changes in direction after reaching a peak. The approach consists of defining two sets of rankings, one corresponding to the observations and the other to the alternative. The test statistic measures the distance between the two sets. The limiting distributions are obtained under the null hypothesis when the location of the peak is known. The simulation study shows good power of the test. A method is proposed for estimating the location of the peak, if it is unknown.
The Ethics of Linguistic Democracy in Schools and Society
Creators: name: Macedo, Donaldo
Publisher: name: Iperstoria
Year: 2019

description: The prohibition of minority languages has profound ethical implications that go beyond the standard “English only versus native language” debate in educational research. Debates regarding monolingualism in teaching curricula that focus solely on individual student success fail to consider the larger social contexts in which languages are important vehicles for culture, community and identity – and, by extension, are important mechanisms for validating students’ sense of self and belonging. What is more, the depoliticizing of language education contributes to a dysfunctional democracy by ignoring the undemocratic nature inherent in the denial of the people’s right to be literate in their first languages as well as in English. In this paper, I argue that academics and teachers who view English-only programs as benefiting minority students are performing what Paulo Freire in Pedagogy of the Oppressed calls “false charity”, which encourages students to equate their ‘success’ with a form of assimilation that, despite the student’s achievements in mastering English, is never fully acknowledged by dominant society – a society that will simply continue to view non-White English speakers as well as non-English speakers as ‘other’ when the suppression of their native languages is legitimized. ‘Charitable’ teachers may inadvertently perpetuate the underlying racist and ethnocentric views of dominant society by ignoring this fact and defaulting to English-only teaching as the best way to help students. Instead, one of the ways teachers can challenge embedded racism and ethnocentrism of dominant society is to remove the conditions that privilege academic English as the only tolerated language and deny or devalue the use of other languages so that students feel they must ‘give up’ a part of themselves and their community to succeed in the dominant culture.

Punchscan: Designing an independent verification mechanism for elections

Subjects: subject: Engineering, Electronics and Electrical.

description: Punchscan is an open-source vote-counting system, the results of which are independently verifiable by voters through their participation in the election audit process. Voluntary and universally available, this audit process establishes an overwhelmingly high statistical degree of confidence in the integrity of the outcome. At the same time it was developed around the recognition that the secret-ballot, and in turn voter privacy, remain a fundamental requirement in modern democracies. Punchscan offers voters the ability to "see their vote count," while at the same time protecting against improper influence. This thesis describes the design and development of Punchscan from an information security and system design perspective. It begins by examining the concerns over contemporary electronic vote-counting systems, and introduces principles (such as independent verification) from which a more secure system can be built. We go on to explore the functional components, their design purpose, and the election/verification procedures of Punchscan. We present a case study of Punchscan's first use in a binding election. Finally we end with a discussion of how Punchscan met its design goals, and propose directions for future work.
Performance evaluation of multicast routing protocol in WiMAX multi-hop relay environment
Creators: name: He, Chengxuan
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Engineering, Electronics and Electrical.

description: Multicast/Broadcast Service (MBS) in WiMAX refers to the ability of the WiMAX network to provide flexible and efficient mechanisms to send common content to multiple users who are sharing radio resources. WiMAX multi-hop relay technology is a key enabler to expand WiMAX infrastructure to eliminate blind spots in coverage and to enhance user throughput with a lower capital expenditure and operational expenditure. To support MBS in a WiMAX multi-hop relay network, one must consider several design issues such as the dynamic relay topology discovery in response to the mobility of the relay station, the dynamic group membership management, the service activation due to join/leave operations of MBS users, the radio resource allocation and the connection management to support these dynamic behaviors. This thesis studies and develops a WiMAX relay architecture, its relay protocol and the optimal multicast algorithms to solve the above issues. To resolve the above-mentioned issues, we have created a model for our multi-hop WiMAX relay architectures. This model incorporates an inter-layer protocol design that would allow the IP layer to use its IGMP/PIM snooping capability together with WiMAX MAC layer relay protocols. Among the MBS server, the WiMAX BS (Base Station) and the MS (Mobile Station), we adopted existing IETF protocols (including IGMP and PIM) to implement some common multicast procedures at the networks layer in order to provision MBS service. To support dynamic formation of a relay network topology, we have proposed and implemented a BS-oriented source-routing protocol to automatically discover the relay path. Finally, we have implemented our MBS in an OPNET simulator, and verified their operations. We have also evaluated the performance of the video and voice applications in WiMAX relay networks under different network sizes, and discussed their performances. The performance results demonstrate the Point to Multi-Point characteristic of WiMAX.

description: The presence on wheat crops of the fungal pathogen Fusarium graminearum poses serious financial and health-related problems in Canada. The fungus causes a significant decrease in yield and quality of the crop, in addition to producing mycotoxins, which can survive the milling process. Signaling processes involving protein kinases are thought to play a major role in the activation of a host defense response. A research project employing western detection experiments and kinase assays was initiated to determine whether the presence of F. graminearum caused changes in the level of protein kinases in cultivars Frontana (resistant) and Roblin (susceptible). The results indicated that F. graminearum had modest effects on phosphorylation levels of threonine and tyrosine residues. Moreover, differences occurred between the resistant and susceptible cultivar. Kinase assays did not show any variation in activity in either cultivar. A MAPK (w&barbelow;heat M&barbelow;APK h&barbelow;omologue-1&barbelow;) homologue was cloned, sequenced and shown to be identical to the wck-1 sequence found in the public database. Preliminary results show an increase in the level of transcript in the Fusarium-treated Frontana sample. The implications of the results are discussed.

description: 'Darryl Kerrigan would have been so proud - the locals cheering outside the Mildura Council offices certainly were. After a concerted community campaign they had beaten the State Government into submission and had saved their bit of 'castle' (well patch of land) from a toxic waste dump.' This comment in The Age, ten years after the release of The Castle (Rob Sitch, 1997), obviously counts on the name of its protagonist to be sufficiently well known as to need no further explanation, and the film's title is alluded to only in the oblique reference to 'castle'. At very least, this suggests something significant about the film's status in the popular imagination.
Mother-baby togetherness: A survey of women's postpartum experiences in four maternity units

Subjects: subject: Health Sciences, Obstetrics and Gynecology.
subject: Health Sciences, Nursing.

description: Purpose. To describe women's postpartum experiences with mother-baby togetherness in hospital, and the concordance of their experiences with the recommendations from Health Canada (2000a) on family-centred maternity and newborn care (FCMNC). Design. Descriptive study based on secondary analysis of a telephone survey conducted at one week and six weeks postnatally. Five elements reported by women were examined: the timing of first physical contact, physical proximity during the first few hours, transfer together to postnatal unit, rooming-in, and combined mother-baby care. Setting. Four maternity units in Ottawa (Ontario, Canada) including two level I units, one level II and one level III unit. A proportionate sample was drawn from each unit. The overall response rate to both interviews was 88.3%. Participants. Women (N = 552) who returned home with their babies within the first postnatal week, between October 2000 and March 2001. Findings. While in hospital, 95.8% of mothers and babies were separated. Combined care was reported by 84.7% of women and rooming-in by only 33.9% of women. Only 8.8% of women experienced all five FCMNC recommended practices. Practices varied between the units (p < .001). Women who had a caesarean birth were more likely to be separated from their infants than those who had a vaginal birth. Routine procedures performed in the nursery was the most frequently reported reason (55.8%) for the first separation of mothers and babies. Conclusion. Few women reported receiving care based on the FCMNC recommendations about mother-baby togetherness. Hospital practices varied considerably. It is recommended that healthy newborns receive care at their mothers' bedside. Further research is recommended to study the relationship between unit policy, actual practices, nurses' beliefs and women's preferences about the elements of mother-baby togetherness.

Subjects: subject: Literature, Canadian (French).

description: François Hertel était un intellectuel catholique et nationaliste à l'avant-scène de la vie littéraire, dans les années trente et quarante au Canada français. Ses premières oeuvres restituent dans leur essence le discours de (époque sur la nation, la politique, l'économie, la culture et le sort réservé a la jeunesse. Ses trois premiers essais, Leur inquiétude (1936), Pour un ordre personnaliste (1942) et Nous ferons l'avenir (1945), méritent d'être relus. On les associe naturellement au roman Le beau risque, une oeuvre nationaliste elle aussi, leur synthèse en quelque sorte. Leur inquiétude témoigne de la déférence de Hertel pour la France, caractéristique d'une époque où la mère patrie était encore une référence essentielle. Pour un ordre personnaliste nous plonge au coeur de la querelle philosophique sur l'individu, la personne et la société. Dans Nous ferons l'avenir, Hertel presse ses compatriotes de se pénétrer d'une mystique nationale positive, et de se défaire de leur attitude de vaincus et d'inférieurs. Enfin, le discours religieux, philosophique et nationaliste de Hertel devient celui de Pierre Martel, le héros du roman Le beau risque. Hertel convie l'adolescent, et toute la jeunesse avec lui, a créer un État français et catholique sur les bords du Saint-Laurent.
New unitary space-time codes with high diversity products

Subjects: subject: Engineering, Electronics and Electrical.

description: We propose new unitary space-time codes with high diversity products for multiple antenna wireless communications. These Hamiltonian and product constellations have full diversity, and can be used for any number of transmitter antennas and for any data rate. Hamiltonian constellations for-two transmitter antennas are based on Slepian's group codes. We construct Hamiltonian constellations for any M transmitter antennas by using a direct sum of 2 x 2 Hamiltonian matrices for M even, and a direct sum of 2 x 2 Hamiltonian matrices with the roots of unity for M odd. Product constellations are proposed using a product of a Hamiltonian constellation and a representation of cyclic group. We also present product constellations of two Hamiltonian constellations with diagonal blocks in different order for M odd. Many of our constellations outperform, and have higher diversity products, than the best known space-time constellation designs in the literature.
System integration: Application of Web-based DBMS and intelligent agent.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Computer Science.

description: Considering the redundancy and the irrelevancy of current search engines in the World Wide Web (WWW), this thesis explores an alternative web-based method of Internet search and retrieval of information via an Intelligent Agent. The Intelligent Agent retrieves the information back to users and it inserts this information automatically into the users' database. There are three components in this system: (1) Multiple User Dungeon (MUD) as a front end, (2) dynamic database management system, and (3) Intelligent Agent as a back end. The front end is a web site open to all the users of this system. It allows different users to access the system simultaneously from different PCs inside the same Intranet. The DBMS database system is designed using Microsoft Access. It is the reservoir of all the data. It provides information to the front end when the users query the database. Intelligent agent (back-end) is implemented using Visual C++ 6.0. It takes advantage of the technique of Open Database Connectivity (ODBC) to connect to the DBMS. The Intelligent Agent searches the Internet through the search engine of Google and then inserts the records into the database based on the user preference. The Intelligent Agent can also update the database by deleting the obsolete records automatically. In order to test and implement this application system, it is applied two business cases: (1) Fisheries Resource Conservation Council (FRCC) and (2) Sport Utility Vehicle (SUV) database system. DBMS and back-end are transparent to users. Users simply need to manipulate the front end interface that links the user to all database review and modification functions, as well as to the search and automatic retrieval options. Results of the implementation of the applications are presented and future research applications for Internet information search and retrieval processes are discussed.
Perception of synchrony between auditory and visual stimuli.
Creators: name: Lee, Catherine.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Psychology, Experimental.

description: The literature has fairly consistently reported a difference in how well humans perceive synchrony depending on the order of auditory and visual stimuli. When the auditory stimulus occurs first and the visual stimulus follows, subjects are more sensitive and so perceive asynchrony with smaller time delay between the stimuli. On the other hand, when the auditory follows the visual stimulus, the subjects are more tolerant and perceive stimuli with larger time delays as synchronous. Thresholds of synchrony perception in these two conditions are thus asymmetrical. The present study attempts to test the Lewkowicz Model, by which the asymmetrical thresholds are explained as a result of arrival-time differences between auditory and visual stimuli to the brain, such that visual stimulus takes longer in processing to be perceived versus auditory one. Reaction-times to these stimuli were measured to determine the arrival-time difference and plotted with synchrony perception. On the basis of Lewkowicz Model we predicted that reaction-time difference between the two stimuli correlate with subjective synchrony. The results did not support the Lewkowicz Model. The expected tendency of 30--40ms of subjective synchrony was not shown. The subjects took, in average, only 7.7ms to detect asynchrony when the auditory stimulus followed the visual stimulus. That the subjects did not tolerate greater temporal gap when the auditory followed versus when it preceded the visual stimulus was a very different result from majority of previous studies. Different factors in perceiving synchrony are discussed in this paper, as well as the application of the research in telecommunications.

Cette analyse revet une forme triple, ce qui correspond aux trois moments du deploiement de l'Esprit selon le syllogisme dialectique de Hegel. Premierement, la guerre permet le deploiement de l'Esprit dans son moment d'immediatete: c'est la guerre dans le developpement de la souverainete interne de l'Etat. Deuxiemement, la guerre permet le deploiement de l'Esprit dans son moment de particularite: c'est la guerre dans le developpement de la souverainete externe de l'Etat. Troisiemement, la guerre permet le deploiement de l'Esprit dans son moment de singularite: c'est la guerre dans le developpement de l'Esprit Universel. Bien qu'etant discrete dans les ecrits du mai tre, la guerre occupe pourtant une place centrale dans la pensee de Hegel: elle rend possible le deploiement de l'Esprit.
Serological identification and characterization of new HLA class I and non-HLA antigens.

Subjects: subject: Biology, General.

description: This report embarks on an investigation of the ethnic diversity, using alloantisera, of three groups of HLA class I antigens, namely A2, A11, and C-locus antigens, and to define antigens that might be restricted to certain ethnic populations. As transplantation therapy has been widely accepted as the choice of treatment for patients with severe haematological disorders, such as acute leukemia, it is essential to match MHC antigens of unrelated donor and recipient pairs to avoid graft rejection or graft-versus-host disease and to reduce administration of immune suppressants. Results obtained from this study indicate that HLA-A2 consists of at least four variants as measured by isoelectric focusing assay. However, only three serological variants are demonstrated by alloantisera. Results further confirmed that two variants of HLA-A11 exist, as measured by serology and isoelectric focusing. The more frequent variant, A11.1, is found in donors of all ethnic backgrounds. The less frequent variant, A11.2, is found only in Oriental populations. This study also reveals two "new" serologically defined HLA-C locus antigens: HLA-Cw Hunt and HLA-Cw Grace. These two "new" antigens are found in Black, Caucasian, East Indian and Oriental ethnic groups. Identification of these two new C-locus antigens reveals that approximately 11% of the population was falsely typed and possess only one or no C-locus antigen. This study also identifies for the first time an alloantiserum that defines an ethnic-specific human minor histocompatibility antigen, hmH$\Phi,$ found only in the Oriental population with a frequency of approximately 5.5%. It was not found in 1,000 Caucasian, 200 East Indian, and 60 Black blood donors. (Abstract shortened by UMI.)
Colloidal stabilization of CeO2 nanomaterials with polyacrylic acid, polyvinyl alcohol or natural organic matter

description: Engineered nanomaterials (ENM) such as nano-sized cerium dioxide (CeO2) are increasingly applied. Meanwhile, concerns on their environmental fate are rising. Understanding the fate of ENM within and between environmental compartments such as surface water and groundwater is crucial for the protection of drinking water resources. Therefore, the colloidal stability of CeO2 ENM (2 mg L-1) was assessed with various surface coatings featuring different physico-chemical properties such as weakly anionic polyvinyl alcohol (PVA), strongly anionic polyacrylic acid (PAA) or complex natural organic matter (NOM) at various water compositions in batch experiments (pH 2 - 12, ionic strength 0-5 mM KCl or CaCl2). While uncoated CeO2 ENM aggregate in the range of pH 4-8 in 1 mM KCl solution, the results show that PAA, PVA and NOM surface coatings stabilize CeO2-ENM at neutral and alkaline pH in 1 mM KCl solution. Stabilization by PAA and NOM is associated with strongly negative zeta potentials below -20 mV, suggesting electrostatic repulsion as stabilization mechanism. No aggregation was detected up to 5 mM KCl for PAA- and NOM-coated CeO2 ENM. In contrast, CaCl2 induced aggregation at >2.2 mM CaCl2 for PAA and NOM-coated CeO2 ENM respectively. PVA-coated ENM showed zeta potentials of -15 mV to -5 mV in the presence of 0-5 mM ionic strength, suggesting steric effects as stabilization mechanism. The hydrodynamic diameter of PVA-coated ENM was larger compared to PAA and NOM at low ionic strength, but the size did not increase with ionic strength of the suspensions. The effect of ionic strength and counter ion valency (pH 7) on the colloidal stability of ENM depends on the prevailing stabilization mechanism of the organic coating. NOM can be similarly effective in colloidal stabilization of CeO2-ENM as PAA. Our results suggest natural Ca-rich waters will lead to ENM agglomeration even of coated CeO2-ENM. © 2018 The Authors.

Mind Reading and Mind Blindness in The Age of Innocence. A Cognitive Perspective
Creators: name: Benedi, Pilar Martinez
Publisher: name: Iperstoria
Year: 2019

description: This essay explores Edith Wharton’s narrative strategies in The Age of Innocence from a cognitive perspective. My purpose is less to describe the cognitive mechanism underlying the act of reading than to reflect on how writers may capitalize on our cognitive proclivities to achieve a certain effect—in this case, surprise. Starting from the notion of “theory of mind” or “mind-reading”—the ability to understand others’ outward behavior in terms of underlying mental or emotional states, which, according to some cognitive critics, “makes literature as we know it possible”—I explore the ways in which this cognitive proclivity to read fictional minds can be turned on its head, and into a kind of “mind-misreading.” With all its silences and “undertelling,” The Age of Innocence, it seems, summons the reader’s theory of mind proclivities. However, in Wharton’s novel the reader’s apparently free “mind-readings” are compromised and manipulated by a fluid focalization and, on the other hand, by an artful use of “mind-blinding” mechanisms that tease our cognitive endowments (together with the protagonist’s), turning an apparently everyday task of mind-reading into an unacknowledged case of (literary) mind-blindness.

description: This study addresses the problem of amino acid compositional bias in molecular phylogenetic reconstruction based on protein sequences. Compositional bias is a factor that has largely been left out of conventional phylogenetic analyses, but there is now reason to believe that it is a significant factor. It is shown that in animal mitochondria homologous genes that differ in AT/GC content code for proteins differing in amino acid content in a manner which reflects the AT and GC content of the codons. This relationship is also seen in nuclear and bacterial genes, and is significant even in the highly-conserved hsp70 and $ef 1\alpha / tu$ genes. This bias in the amino acid content of proteins can result in incorrect protein-based phylogenetic trees. A striking example is presented where common phylogenetic tools fail to recover the correct tree from animal mitochondrial protein sequences. The two taxa with the greatest compositional bias continually group together in these analyses, despite a lack of close biological relatedness. It is concluded that, while protein-based phylogenetic analyses have been favoured over analyses using biased DNA, even protein-based trees can be misleading. Current models of protein sequence evolution used for phylogenetic reconstruction assume that the amino acid composition is stationary. In order to accommodare evolution involving compositional change, directional mutation probability models are proposed and their properties described. In simulation studies with biased and non-biased branches on the same tree, the biased branches "attract" in subsequent analyses, paralleling results about using real mitochondrial sequences. Improved methodology is proposed which can use both stationary and directional models in phylogenetic reconstruction, and which can use different models on different branches of the same phylogenetic tree.

description: This paper explores the cultural (and psychological) attitudes toward black people’s hair and hairstyles and their significance in the formation of race relations. Starting from analysing the social, political and religious meanings associated to hair in pre-colonial Africa, the text individuates the Atlantic Trade as the event at the origin of a revolution in black aesthetics. In fact, before the massive influence of European standards, determinant in changing African men and women’s approach to beauty and appearance, hairstyles in Sub-Saharan Africa used to represent a person’s marital status, the hierarchical position in a community, the devotion to a particular cult. The Slavery Era, depriving individuals of their cultures’ peculiar elements, caused the loss of many hair’s social and spiritual symbols, although inaugurating new approaches and symbolisms in hairstyles and black beauty culture. From mere imitation of masters’ haircut and wigs, to afros, dreadlocks and cornrows, African-American and African-Caribbean communities’ hairstyles reflect political choices, social condition and self-perception in accordance to the historical period. Observing the evolution of hairstyles through the decades, the essay covers a temporal journey until the current times, finding in hair an instrument to understand the impact of Western paradigms on black identity.

description: Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease in Canada and is characterized by a clinical syndrome of episodic inflammatory symptoms. Traditionally, the disease is defined by autosomal recessive inheritance of MEFV gene variants, yet FMF also not uncommonly manifests in individuals with only one identified disease-associated allele. Increasing availability and affordability of gene sequencing has led to the identification of multiple MEFV variants; however, they are often of unknown clinical significance. Variants in other genes affecting overlapping or distinct inflammatory signaling pathways – together with gene-environment interactions including epigenetic modulation – likely underlie the significant genetic and phenotypic heterogeneity seen among patients with this disease. We review recent evidence of the expanding spectrum of FMF genotype and phenotype and suggest that current drug funding schemes restricting biologic agents to patients with homozygous mutations have not kept pace with our biological understanding of the disease.
Election and termination detection in specialized communication structures.

description: This thesis addresses election and termination detection problems in specialized communication structures. Three communication structures; namely, composite complete network (i.e., a complete network whose size is composite), recursively scalable network and H-mesh, are examined. The objective in considering composite complete networks is to investigate the effect on the message complexity of the election algorithms when N the size of the complete network is composite. Specifically, it is shown that when N is a multiple of 2, 3, 4, 5, or 6, the message complexity of the existing election algorithm for the complete network can be improved. To this end, an hybrid approach to designing election algorithms for complete networks with a sense of direction is developed when N is composite. The approach is based on a well-known divide and conquer paradigm for problem solving. The objective in considering recursively scalable networks and H-meshes is to utilize the underlying communication structure as a guiding factor in the development of election and termination detection algorithms. Furthermore, these communication structures are recently analyzed and are employed as interprocessor communication architectures in the development of message passing multiprocessor systems. An election algorithm in a synchronous recursively scalable network is designed by making use of its hierarchical communication structure. It requires less than 4.5N messages and the running time is at most 2.75$\sqrt{N}$ where N is the number of processors in the network. A termination detection algorithm in a H-mesh is developed. It is based on the propagation of passive state information and on the probe passing technique. Traffic rules for probes and passive state information are designed by making use of the structure of the H-mesh. The correctness proof for the termination detection algorithm is also presented.
A gap-analysis model for identifying effective government support for new technology-based firms (NTBFs) in Thailand
Creators: name: Virasa, Thanaphol
Publisher: name: Swinburne

description: Over the past two decades successive Thai governments have taken a proactive approach to stimulating R&D activities and technology development in Thai companies. Various Thai governments have established policies and measures for supporting New Technology-based Firms (NTBFs) in the nation's infrastructure. Recent Thai governments have shifted their focus towards developing a robust infrastructure for national innovation systems. The stated intention is to create and convert local knowledge into commercially viable outputs to sustain innovative activity. Key pioneering work was carried out by the Thailand Development and Research institute (TDRI) in the mid-1990s (TRDI, 1998). This was followed by work which focused on financial supporting initiatives (Turpin et. al. (2002). Yencken and Hindle (2005) added a further useful dimension by setting out a framework for the creation of new technology-based firms (NTBFs). Part of Yencken and Hindle's (2005) framework suggests that governments should audit their holistic infrastructure and work to fill gaps in the whole network of support. Without this viewpoint, efforts may under-perform. In the current empirical study reported here, the author seeks to develop Yencken and Hindle's (2005) framework in the context of Thailand. Two key concerns are discussed in some depth. Firstly, what policies and measures should the Thai government pursue in order effectively to foster entrepreneurship and innovation? Secondly, how best could the Thai government identify gaps for improving existing policies and measures?
"Where Did We Go From There?": Beasts of the Southern Wild's Resistance to Civil Life

Subjects: American literature, cinema

description: After 50 years from the battles for civil equality in the United States, this essay analyzes the film Beats of the Southern Wild (2012) and its African American characters’ refusal to participate into the civic life of their country. As a consequence of a hurricane that reminds of Katrina, the isolated community of Bathtub is forced to enter into contact with civic institutions with deleterious effect on both Hushpuppy, the 6-year-old protagonist, and her father. While the passage to civilized life has deadly consequences on the man’s precarious health conditions, Hushpuppy is forcedly transformed into an example of mainstream femininity. In this way, Beasts of the Southern Wild casts doubt on the importance of civic belonging as a rewarding act in one’s life. At the beginning of the new millennium, in years that are defined as post-civil rights as well as post-racial, the film shows the oppressive force of civil life and the state, which transforms rights into abuse of personal choices and lifestyle.

Strategies of Glocalization in Audiovisual Translation: Dubbing Ava Duvernay's Selma into Italian

description: Thirty years on from the exemplary three Selma to Montgomery marches led by Martin Luther King, Ava DuVernay directed the production of a featured movie, Selma, which portrays the complex events that persuasively contributed to the recognition of African Americans’ right to vote. The aim of the film was to celebrate the enormous effort that Martin Luther King and his supporters made in the fight for getting the Civil Rights Acts passed that same year. With the aim of analysing how, and to what extent, King’s oratory skill is exploited to shaping and consequently introducing the iconic figure to the source as well as to the target audience, this essay focuses on Martin Luther King’s linguistic choices both in public speeches and in more private communicative exchanges. The linguistic approach, including a comparative analysis of the two versions, will also shed light on the most relevant changes that the adaptation process for Italian viewers brought about. Such discrepancies (though apparently slight) will prove to be decisively influential in the construction of King’s and other characters’ identities to the point that target viewers can actually encounter ‘different’ characters than in the original version.
