Reinterpreting Canadian national identity : the evolution of national identity in late-nineteenth and early-twentieth century young adult historical fiction
Creators: name: Hiles, Samuel Peter
Publisher: name: University of British Columbia
Year: 2018

description: This thesis presents a comparative analysis of two periods of Canadian young adult historical fiction novels. Its goal is to determine if and how presentations of Canadian national identity changed following a major international event—the First World War. As the War can be seen as a catalyst that accelerated changing interpretations of the Canadian nation the novels selected bookend this event. Through a comparison of young adult historical fiction novels involving Canadian national history, the subjective and narrative characteristics of history are explored to emphasize common features found in both narrative histories and fiction. By relying on young adult historical fiction, which for the purpose of this thesis are texts intended for post-adolescent and pre-adult readers, the fictive aspects of the narratives will function as contrastable variables for analysis. This thesis will evaluate how narratives vary to produce different interpretations and perspectives on the nation’s past, and therefore conceptions of national identity. I contend that works of young adult historical fiction that feature Canada’s past began to express the changes to national identity seen in Canada society that followed the War. These changes to expressions of national identity, I propose, became increasingly evident in fictional narratives depicting the nation’s past and support a more autonomous vision of the nation. How history is retold through fiction stresses how conceptions of national identity are susceptible to the contextual nature of narrative history. Canada’s late-nineteenth century relationship with imperialism, as interpreted from within the English-Canadian dominant national narrative, operates as the major evaluative theme to contrast fictional accounts of the nation’s past. The following study sets Canada’s pre-War relationship with Britain against Canada’s post-War waning colonial identification as baseline identities for inquiries into how historical fiction narratives re-envisioned the past. This research summarizes how unique and autonomous national imaginings were extracted from Canada’s colonial heritage to express an evolving vision of the nation. Focusing on the evolution of Canadian national identity, as it manifests in young adult historical fiction, the contextual nature of historical narratives becomes recognizable, thereby, prompting reflections on history and the relative nature of narrativity.

description: Collaborative tagging has emerged as a popular and effective method for organizing and describing pages on the Web. We present Treelicious, a system that allows hierarchical navigation of tagged web pages. Our system enriches the navigational capabilities of standard tagging systems, which typically exploit only popularity and co-occurrence data. We describe a prototype that leverages the Wikipedia category structure to allow a user to semantically navigate pages from the Delicious social bookmarking service. In our system a user can perform an ordinary keyword search and browse relevant pages but is also given the ability to broaden the search to more general topics and narrow it to more specific topics. We show that Treelicious indeed provides an intuitive framework that allows for improved and effective discovery of knowledge.

description: In recent years, DNA barcoding has become quite popular for molecular identification of species because it is simple, quick and an affordable method. Present study was conducted to identify spiders of most abundant families, i.e. Salticidae and Lycosidae from citrus orchards in Sargodha district using DNA barcoding. A total of 160 specimens were subjected to DNA barcoding but, sequences up to 600 bp were recovered for 156 specimens. This molecular approach proved helpful to assign the exact taxon to those specimens which were misidentified through morphological characters in the study. We were succeeded to discriminate six species of Lycosidae and nine species of Salticidae through DNA barcoding. Results revealed the presence of clear barcode gap (discontinuity in intra- and inter-specific divergences) for members of both families. Furthermore, the maximum intra-specific divergence was less than NN (nearest neighbour) distance for all species. This suggested the reliability of DNA barcoding for spider’s identification up to species level. We got 98% success in our study. It is concluded from present study that DNA barcoding is more reliable tool especially for immature spiders, when morphological characters are ambiguous.

description: Monitor lizards are Varanus species widely distributed, endangered reptile in the IUCN red data list. In India, based on the morphological and ecological characteristic, it is divided into four species viz. Bengal monitor lizard, Yellow monitor lizard, Desert monitor lizard and Water monitor lizard. These four species listed as Schedule I species in Indian Wildlife (Protection) Act 1972. This paper first attempt to present Forensically Informative Nucleotide Sequencing (FINS) for the Indian Varanus based on three mitochondrial genes. The molecular framework will be useful for the identification of Indian Varanus species and trade products derived from monitors and as such, have important applications for wildlife management and conservation. Here, we used known 14 individual skin pieces of four species of monitor lizards; the partial fragment of three mitochondrial genes (Cyt b, 12S rRNA, and 16S rRNA) were amplified for genetic study. In Cyt b, 12S rRNA and 16s rRNA, we observed, 5, 5 and 4 Haplotypes; 71, 69, and 43 Variables sites; 90, 89, and 50 Parsimony Informative sites within four species of Indian monitor lizards, respectively. Despite it, the nucleotide composition was T 26.4, C 32.8, A 29.2 and G11.6; T 18.8, C 29.7, A 34.0 and G 17.5; T 21.7, C 27.3, A 32.5 and G 18.5 in Cyt b, 12S rRNA and 16S rRNA, respectively. The neighbor joining phylogenetic tree and maximum parsimony tree of three mitochondrial genes, showed similar results and reveal that, there are two major clades are present in Indian monitor lizards.

description: Abridged. We have performed an ecliptic survey of the Kuiper belt, with an areal coverage of 8.9 square degrees to a 50% limiting magnitude of r'=24.7, and have detected 88 Kuiper belt objects, roughly half of which received follow-up one to two months after detection. Using this survey data alone, we have measured the luminosity function of the Kuiper belt, thus avoiding any biases that might come from the inclusion of other observations. We have found that the Cold population defined as having inclinations less than 5 degrees has a luminosity function slope alpha=0.82+-0.23, and is different from the Hot population, which has inclinations greater than 5 degrees and a luminosity function slope alpha=0.35+-0.21. As well, we have found that those objects closer than 38 AU have virtually the same luminosity function slope as the Hot population. This result, along with similar findings of past surveys demonstrates that the dynamically cold Kuiper belt objects likely have a steep size distribution, and are unique from all of the excited populations which have much shallower distributions. This suggests that the dynamically excited population underwent a different accretion history and achieved a more evolved state of accretion than the cold population. As well, we discuss the similarities of the Cold and Hot populations with the size distributions of other planetesimal populations. We find that while the Jupiter family comets and the scattered disk exhibit similar size distributions, a power-law extrapolation to small sizes for the scattered disk cannot account for the observed influx of comets. As well, we have found that the Jupiter Trojan and Hot populations cannot have originated from the same parent popuation, a result that is difficult to reconcile with scattering models similar to the NICE model.

description: We use “real donation” laboratory experiments to compare independent fundraising, where donation requests from different charities arrive sequentially to potential donors, with collaborative fundraising, where donation requests from different charities arrive simultaneously. We find that collaborative fundraising generates significantly larger total donations compared to independent fundraising. We show that the order of requests affects the level of donations only in independent fundraising; in particular, participants donated larger amounts to charities whose requests arrived earlier. We then test whether these differences might be explained by the informational asymmetry between these two fundraising mechanisms by varying the information received by the subjects.

description: The transverse charge density in the pion can be represented as a dispersion integral of the imaginary part of the pion form factor in the timelike region. This formulation incorporates information from e+e- annihilation experiments and allows one to reconstruct the transverse density much more accurately than from the spacelike pion form factor data alone. We calculate the transverse density using an empirical parametrization of the timelike pion form factor and estimate that it is determined to an accuracy of ~10% at a distance b ~ 0.1 fm, and significantly better at larger distances. The density is found to be close to that obtained from a zero-width rho meson pole over a wide range and shows a pronounced rise at small distances. The resulting two-dimensional image of the fast-moving pion can be interpreted in terms of its partonic structure in QCD. We argue that the singular behavior of the charge density at the center requires a substantial presence of pointlike configurations in the pion's partonic wave function, which can be probed in other high-momentum transfer processes.

description: This paper extends several previous studies of wormholes supported by two non-interacting fluids beginning with a combined model of ordinary matter and phantom dark energy with an anisotropic matter distribution. After noting that such wormholes could only exist on very large scales, the two-fluid model is extended to neutron stars, previously treated only for the isotropic case. The model is completed by incorporating certain generic features proposed by the author in an earlier study.

description: The mitochondrially encoded NADH:ubiquinone oxidoreductase core subunit 1 (MT-ND1) gene is a subunit of the respiratory chain complex I and involved in the first step of the electron transport chain of oxidative phosphorylation (OXPHOS). To understand the pattern of compositional properties, codon usage and expression level of mitochondrial ND1 genes in pisces, aves, and mammals, we used bioinformatic approaches as no work was reported earlier. In this study, a perl script was used for calculating nucleotide contents and different codon usage bias parameters. The codon usage bias of MT-ND1 was low but the expression level was high as revealed from high ENC and CAI value. Correspondence analysis (COA) suggests that the pattern of codon usage for MT-ND1 gene is not same across species and that compositional constraint played an important role in codon usage pattern of this gene among pisces, aves, and mammals. From the regression equation of GC12 on GC3, it can be inferred that the natural selection might have played a dominant role while mutation pressure played a minor role in influencing the codon usage patterns. Further, ND1 gene has a discrepancy with cytochrome B (CYB) gene in preference of codons as evident from COA. The codon usage bias was low. It is influenced by nucleotide composition, natural selection, mutation pressure, length (number) of amino acids, and relative dinucleotide composition. This study helps in understanding the molecular biology, genetics, evolution of MT-ND1 gene, and also for designing a synthetic gene.

description: We have calculated the electronic structure of Eu for the bcc, hcp, and fcc crystal structures for volumes near equilibrium up to a calculated 90 GPa pressure using the augmented-plane wave method in the local-density approximation. The frozen-core approximation was used with a semi-empirical shift of the f-states energies in the radial Schr$\ddot{o}$dinger equation to move the occupied 4f valence states below the $Γ_1$ energy and into the core. This shift of the highly localized f-states yields the correct europium phase ordering with lattice parameters and bulk moduli in good agreement with experimental data. The calculated superconductivity properties under pressure for the $\it bcc$ and $\it hcp$ structures are also found to agree with and follow a $T_c$ trend similar to recent measurement by Debessai et al.$^1$

description: We study the conductance of mesoscopic graphene rings in the presence of a perpendicular magnetic field by means of numerical calculations based on a tight-binding model. First, we consider the magnetoconductance of such rings and observe the Aharonov-Bohm effect. We investigate different regimes of the magnetic flux up to the quantum Hall regime, where the Aharonov-Bohm oscillations are suppressed. Results for both clean (ballistic) and disordered (diffusive) rings are presented. Second, we study rings with smooth mass boundary that are weakly coupled to leads. We show that the valley degeneracy of the eigenstates in closed graphene rings can be lifted by a small magnetic flux, and that this lifting can be observed in the transport properties of the system.

description: The role of graded interfaces between materials in a cylindrical free-standing quantum wire with longitudinal heterostructures is theoretically investigated, by solving the Schrödinger equation within the effective mass approximation. Previous work on such wires with abrupt interfaces have predicted that, as the wire radius is reduced, the effective potential along the growth direction is altered and might lead to a carrier confinement at the barriers, as in a type-II system. Our results show that when graded interfaces are considered, such potential acquires a peculiar form, which presents cusps at the interfacial regions, yielding to electron confinement at interfaces. Numerical results also show that, in some special cases, interfacial confinement and type-I to type-II transitions can also be induced by applying a magnetic field parallel to the wire axis.

description: Species of the genus Nipponacmea inhabit only the Pacific coast of Asia, including the Russian Far East. Their external morphological characters are highly variable and often lead to misidentifications of species. So far, little research has been conducted using molecular markers. We used sequences from three mitochondrial genes (fragments of cytochrome c oxidase subunit I gene (COI), 12S and 16S rDNA). For comparison, additional genetic and taxonomic data on other species belonging to this genus were derived from GenBank. The molecular phylogenetic trees suggest that the species N. fuscoviridis and N. nigrans are species complexes. N. fuscoviridis is divided into three subgroups with high support and relatively large distances between them (N. fuscoviridis A, B and C); N. nigrans fall into two subgroups and one of them (N. nigrans A) is more closely related to N. moskalevi than to the other subgroup of N. nigrans (B).
WEIGHT GAIN PATTERNS ASSOCIATED WITH VAGINAL BIRTH AFTER CESAREAN: A STUDY PROPOSAL
Creators: name: Gomez, Sarah Elisabeth
Publisher: name: Zenodo
Year: 2014

description: Women in the United States desirous of vaginal birth after cesarean (VBAC) have a 60%-80% chance of success. Inability to achieve VBAC may be related to various factors. One such factor, excessive gestational weight gain (GWG), has not been substantively addressed since the 2009 modification of the Institute of Medicine guideline. This retrospective case control study plan addressed the general question: To what extent does GWG predict VBAC? It also will address the more specific question: Do patterns of GWG predict VBAC? Following human subjects review, the proposed study will analyze data from women who attempted a trial of labor managed by a hospital based Nurse-Midwifery service with a 78% VBAC success rate. The hypothesis that there is a relationship between excessive GWG and decreased rate of VBAC will be tested using logistic regression. The sample will be described in terms of age and race/ethnicity, along with maternal and pregnancy conditions (e.g., comorbidities, history). Analysis will determine whether achievement of VBAC (yes/no) is related to GWG. This inquiry may highlight the importance of prenatal education to patients related to optimal weight gain in woman planning to attempt a trial of labor hoping to achieve VBAC. The results should identify needs for future research and information for targeting better education, treatment, and strategy to provide a safe, evidence-based environment for these women prior to, and during pregnancy.

description: A new cosmic shear analysis pipeline SUNGLASS (Simulated UNiverses for Gravitational Lensing Analysis and Shear Surveys) is introduced. SUNGLASS is a pipeline that rapidly generates simulated universes for weak lensing and cosmic shear analysis. The pipeline forms suites of cosmological N-body simulations and performs tomographic cosmic shear analysis using line-of-sight integration through these simulations while saving the particle lightcone information. Galaxy shear and convergence catalogues with realistic 3D galaxy redshift distributions are produced for the purposes of testing weak lensing analysis techniques and generating covariance matrices for data analysis and cosmological parameter estimation. We present a suite of fast medium resolution simulations with shear and convergence maps for a generic 100 square degree survey out to a redshift of z = 1.5, with angular power spectra agreeing with the theory to better than a few percent accuracy up to l = 10^3 for all source redshifts up to z = 1.5 and wavenumbers up to l = 2000 for the source redshifts z > 1.1. At higher wavenumbers, there is a failure of the theoretical lensing power spectrum reflecting the known discrepancy of the Smith et al. (2003) fitting formula at high physical wavenumbers. A two-parameter Gaussian likelihood analysis of sigma_8 and Omega_m is also performed on the suite of simulations, demonstrating that the cosmological parameters are recovered from the simulations and the covariance matrices are stable for data analysis. We find no significant bias in the parameter estimation at the level of ~ 0.02. The SUNGLASS pipeline should be an invaluable tool in weak lensing analysis.

From the margins : cultural safety from an Okanagan/Sqilxw perspective
Creators: name: Mitchell, Vanessa
Publisher: name: University of British Columbia
Year: 2018

description: The purpose of this research project was to examine cultural safety from an Okanagan/Sqilxw perspective. Cultural safety is a term that originated in New Zealand with the Maori people in their need to address the health disparities and power imbalances within the institution of health. As cultural safety has become adapted in practice within the Interior Region, it became necessary to examine the concept closer with peoples of the Interior. As the Syilx (Okanagan) are one of the seven First Nations located in the Interior Region, and of which I am a member, this project was primarily conducted with Okanagan/Sqilxw members of the Okanagan Indian Band. The research was guided by participatory action research and Indigenous methodologies. The analytical framework was based on the enowkinwixw, which is an Okanagan/Sqilxw decision making process that undertakes serious issues of concern in the community. In order to ground this research in community, it was equally necessary that I abide by community ethics. Therefore, an Advisory Committee, formed solely of Okanagan Indian Band members, held my research and me accountable to community. Talking Circles was how community members were brought together to break down the terms culture and safety, and to discuss what cultural safety meant to them. In analyzing the contribution from community members, it is integral for Okanagan/Sqilxw to gain cultural confidence; that is, the confidence to voice one’s or people’s concerns and direction. Further, it is cultural safety that community and mainstream healthcare must strive for. Both are an investment in a lifelong journey into one’s self.

description: The degradation of the hemi-wicking property of superhydrophilic high-energy surfaces due to contaminant adsorption from the ambient atmosphere is well documented. This degradation compromises the performance of such surfaces, thus affecting their efficacy in real-world applications where hemi-wicking is critical. In this work, the role of surface micro/nanostructure morphology of laser-textured metallic surfaces on superhydrophilicity degradation is studied. We explore intrinsic contact angle variations of superhydrophilic surfaces via adsorption of organics from the surroundings, which brings about the associated changes in surface chemistry. Furthermore, we explore condensation from humid air as a scalable and environment friendly methodology that can reinstate surface superhydrophilicity to a considerable extent (64% recovery of intrinsic wettability after three hours of condensation) due to the efficient removal of physisorbed contaminants from the surface texture features. The present results strengthen the argument that contact-line movement at fine scales can be used for de-pinning and removal of adsorbed organic molecules from contaminated surfaces.

description: Solenodons are insectivores found only in Hispaniola and Cuba, with a Mesozoic divergence date versus extant mainland mammals. Solenodons are the oldest lineage of living eutherian mammal for which a mitogenome sequence has not been reported. We determined complete mitogenome sequences for six Hispaniolan solenodons (Solenodon paradoxus) using next-generation sequencing. The solenodon mitogenomes were 16,454–16,457 bp long and carried the expected repertoire of genes. A mitogenomic phylogeny confirmed the basal position of solenodons relative to shrews and moles, with solenodon mitogenomes estimated to have diverged from those of other mammals ca. 78 Mya. Control region sequences of solenodons from the northern (n = 3) and southern (n = 5) Dominican Republic grouped separately in a network, with FST = 0.72 (p = 0.036) between north and south. This regional genetic divergence supports previous morphological and genetic reports recognizing northern (S. p. paradoxus) and southern (S. p. woodi) subspecies in need of separate conservation plans.

description: In this study, we investigated the association of mtDNA variants and haplogroups with Type 2 diabetes (T2D) in Moroccan patients. The Hypervariable Segments 1 of the mtDNA was sequenced in 108 diabetic patients and 97 controls. Association analyses were performed using Fisher’s exact test and multivariate logistic regression. The prevalence of five mtDNA variants (C16187T, C16270T, T16172C, A16293G, and C16320T) was significantly higher in cases than in controls. Among these variants, only C16270T (p = .02) and C16320T (p = .03) remains significant after adjusting by age and gender. We showed that C16270T and C16320T variants were strongly associated with increased risk of T2D in Moroccan patients.

description: We perform a global analysis of the space of consistent 6D quantum gravity theories with N = 1 supersymmetry, including models with multiple tensor multiplets. We prove that for theories with fewer than T = 9 tensor multiplets, a finite number of distinct gauge groups and matter content are possible. We find infinite families of field combinations satisfying anomaly cancellation and admitting physical gauge kinetic terms for T > 8. We find an integral lattice associated with each apparently-consistent supergravity theory; this lattice is determined by the form of the anomaly polynomial. For models which can be realized in F-theory, this anomaly lattice is related to the intersection form on the base of the F-theory elliptic fibration. The condition that a supergravity model have an F-theory realization imposes constraints which can be expressed in terms of this lattice. The analysis of models which satisfy known low-energy consistency conditions and yet violate F-theory constraints suggests possible novel constraints on low-energy supergravity theories.

description: A detailed observation of microglitch phenomenon in relatively slow radio pulsars is presented. Our analyses for these small amplitude jumps in pulse rotation frequency ($ν$) and/or spin down rate ($\dotν$) combine the traditional manual detection method (which hinges on careful visual inspections of the residuals of pulse phase residuals) and a new, and perhaps more objective, automated search technique (which exploits the power of the computer, rather than the eyes, for resolving discrete events in pulsar spin parameters). The results of the analyses of a sample of 26 radio pulsars reveal that: (i) only 20 pulsars exhibit significant fluctuations in their arrival times to be considered suitable for meaningful microglitch analyses; (ii) a phenomenal 299 microglitch events were identified in $ν$ and/or $\dotν$: 266 of these events were found to be simultaneously significant in $ν$ and $\dotν$, while 19 and 14 were noticeable only in $ν$ and $\dotν$, respectively; (iii) irrespective of sign, the microglitches have fractional sizes which cover about 3 orders of magnitude in $ν$ and $\dotν$ ($10^{-11} < |Δν/ν| < 2.0\times10^{-8}$ and $5.0\times10^{-5} < |Δ{\dotν}/\dotν| < 2.0\times10^{-2}$) with median values as $0.78\times10^{-9}$ and $0.36\times10^{-3}$, respectively.

Hotel recommendation system
Collaborative filtering
Cold start issue

description: This thesis investigates the development of an effective hotel recommendation system by leveraging neural networks and advanced modeling techniques. The present research aims to comprehend the difficulties related to recommendation systems, specifically collaborative filtering and the cold start issue. The study investigates deep and recurrent neural networks and their training procedures to develop strong model architectures that enhance recommendations. The experiments involve processing datasets, performing analytics, and developing various models such as Deep Average Network (DAN), and sequential model variations. Innovative solutions, such as embedding enhancement and a hotel embeddings calculator, are proposed to tackle the cold start problem. The study shows that the suggested method is efficient in improving hotel recommendation systems. The thesis enhances hotel recommendation systems by presenting ideas and techniques that can be further developed and improved in future research.
description: Η παρούσα εργασία διερευνά την ανάπτυξη ενός αποτελεσματικού συστήματος πρότασης ξενοδοχείων με την αξιοποίηση νευρωνικών δικτύων και προηγμένων τεχνικών μοντελοποίησης. Η παρούσα έρευνα αποσκοπεί στην κατανόηση των δυσκολιών που σχετίζονται με τα συστήματα προτάσεων, συγκεκριμένα το συνεργατικό φιλτράρισμα (collaborative filtering) και το ζήτημα της ψυχρής εκκίνησης (cold start). Η μελέτη διερευνά τα βαθιά και τα επαναλαμβανόμενα νευρωνικά δίκτυα και τις διαδικασίες εκπαίδευσής τους για την ανάπτυξη ισχυρών αρχιτεκτονικών μοντέλων που ενισχύουν τις συστάσεις. Τα πειράματα περιλαμβάνουν την επεξεργασία συνόλων δεδομένων, την εκτέλεση αναλύσεων και την ανάπτυξη διαφόρων μοντέλων, όπως το Deep Average Network (DAN), και παραλλαγές μοντέλων. Για την αντιμετώπιση του προβλήματος της ψυχρής εκκίνησης προτείνονται καινοτόμες λύσεις, όπως η ενσωμάτωση υπολογισμένων και μη (raw) embeddings. Η μελέτη δείχνει ότι η προτεινόμενη μέθοδος είναι αποτελεσματική στη βελτίωση των συστημάτων συστάσεων ξενοδοχείων. Η εργασία ενισχύει τα συστήματα ξενοδοχειακών συστάσεων παρουσιάζοντας ιδέες και τεχνικές που μπορούν να αναπτυχθούν περαιτέρω και να βελτιωθούν σε μελλοντικές έρευνες.

description: In recent years, DNA barcoding has become quite popular for molecular identification of species because it is simple, quick and an affordable method. Present study was conducted to identify spiders of most abundant families, i.e. Salticidae and Lycosidae from citrus orchards in Sargodha district using DNA barcoding. A total of 160 specimens were subjected to DNA barcoding but, sequences up to 600 bp were recovered for 156 specimens. This molecular approach proved helpful to assign the exact taxon to those specimens which were misidentified through morphological characters in the study. We were succeeded to discriminate six species of Lycosidae and nine species of Salticidae through DNA barcoding. Results revealed the presence of clear barcode gap (discontinuity in intra- and inter-specific divergences) for members of both families. Furthermore, the maximum intra-specific divergence was less than NN (nearest neighbour) distance for all species. This suggested the reliability of DNA barcoding for spider’s identification up to species level. We got 98% success in our study. It is concluded from present study that DNA barcoding is more reliable tool especially for immature spiders, when morphological characters are ambiguous.
The physical activity and mobility of foreign-born older adults : a multilingual focused ethnography
Creators: name: Tong, Catherine Elisabeth

description: Introduction: Physical activity (PA), the movement of one’s body, and mobility, moving one’s body through space using a variety of modes, allow older adults to participate in their communities, cultivate social connections, maintain their health, and access services. Segments of the population, however, have been overlooked. While a growing body of research has focused on older adults, we know surprisingly little about the PA and mobility of foreign-born older adults (FBOAs). Objective: This dissertation uses a focused ethnographic approach to characterize the PA and mobility of 49 visible minority FBOAs in South Vancouver, Canada. Methods: The research was conducted in Hindi, Punjabi, Cantonese, Mandarin, and English. Forty-nine participants completed surveys about their PA habits; of these 49, 46 wore accelerometers and 18 completed in-depth interviews. I also developed a novel interview tool “interactive interpreted interviews”, neighbourhood walking interviews that included professional interpreters, which 13 participants completed. Results: Participants’ mean daily step count was 7,876 (women: 8,172; men: 7,164; Chinese: 8,291; South Asian: 7,196). The bulk of their time is spent in light and sedentary activities. Physical activity is principally acquired through walking for errands and work performed in/around the home. Participants walk for physical and mental wellbeing, and have access to a supportive social environment, which includes culturally familiar and linguistically accessible shops and services. Conclusions: This study challenges the assumption that FBOAs are less active than their non-immigrant peers and confirms the role of “nonexercise” and low activity, rather than moderate to vigorous activity, in older adults’ PA acquisition. Building on the Webber (2010) model of mobility in older adults, this study also highlights how gender and personal biography, including work history and family context, impact participants’ PA and mobility behaviours.

description: We construct a simple multicomponent lattice gas model in one dimension in which each site can either be empty or occupied by at most one particle of any one of D species. Particles interact with a nearest-neighbor interaction which depends on the species involved. This model is capable of reproducing the relations between factorial moments observed in high-energy scattering experiments for moderate values of D. The factorial moments of the negative binomial distribution can be obtained exactly in the limit as D becomes large, and two suitable prescriptions involving randomly drawn nearest-neighbor interactions are given. These results indicate the need for considerable care in any attempt to extract information regarding possible critical phenomena from empirical factorial moments.

description: Η άσκηση είναι επιστημονικά αποδεδειγμένο ότι επιδρά θετικά τόσο στη σωματική, όσο και στην ψυχική υγεία, ενώ παράλληλα δρα προληπτικά και θεραπευτικά έναντι χρόνιων παθήσεων του ανθρώπινου οργανισμού. Σε πολλές περιπτώσεις αιτία των χρόνιων παθήσεων είναι η φλεγμονή, η οποία προσδιορίζεται με την χρήση συγκεκριμένων βιοδεικτών. Σκοπός αυτής της ανασκόπησης είναι να καταγράψει την μέχρι σήμερα υπάρχουσα γνώση σχετικά με το αν η άσκηση επιδρά σε συγκεκριμένους βιοδείκτες που χαρακτηρίζουν την φλεγμονή. Οι βιοδείκτες που εξετάσθηκαν είναι η IL-6, η CRP, ο TNF-α, και η IL-β. Μετά από μια εκτενή βιβλιογραφική ανασκόπηση δημοσιευμένων μελετών και άρθρων σε υγιή και μη δείγματα πληθυσμού τα οποία αντλήθηκαν από τις ηλεκτρονικές βάσεις δεδομένων Pubmed και Medline των τελευταίων δέκα ετών, σύμφωνα με τη μέθοδο PRISMA,επιβεβαιώνεται ότι τα επίπεδα των παραπάνω βιοδεικτών μεταβάλλονται με την άσκηση ανάλογα με την ένταση, την διάρκεια, την συχνότητα καθώς και με τα διαφορετικά είδη της άσκησης. Το συμπέρασμα αυτό είναι πολύ χρήσιμο για την επιστημονική κοινότητα η οποία μπορεί να εκμεταλλευτεί την επίδραση της άσκησης με τον καλύτερο δυνατό τρόπο ως προς την πρόληψη και μείωση της φλεγμονής στον ανθρώπινο οργανισμό
description: Exercise is scientifically proven to have a positive effect on both physical and mental health, while at the same time it acts preventively and therapeutically against chronic diseases of the human body. In many cases, the cause of chronic diseases is inflammation, which is determined by the use of specific biomarkers. The purpose of this review is to document the current knowledge on whether exercise affects specific biomarkers of inflammation. The biomarkers which were examined are IL-6, CRP, TNF-α, IL-1β. After an extensive bibliographic review of published studies and articles on healthy and non-healthy population samples from the electronic databases Pubmed, Medline of the last ten years, according PRISMA method, it is confirmed that the levels of the above biomarkers change with exercise depending on the intensity, duration, the frequency as well as with the different types of exercise. This conclusion is very useful for the scientific community which it can take advantage of the effect of exercise in the best possible way in terms of preventing and reducing inflammation in the human body.
