description: Following seizure cessation, specific behavioural impairments emerge that reflect the networks involved in ictal activity and extend for tens of minutes to hours. Postictal behavioural dysfunction is epitomized by Todd’s Paresis: limb weakness or paralysis following seizures that begin within or spread to motor cortex. This observation was described over a century ago, yet still lacks physiological explanation and therapies. The similarities shared between postictal behavioural dysfunction and neurological deficits following stroke suggest a potential common mechanism. I hypothesized that seizures result in a period of severe hypoperfusion/hypoxia that is responsible for behavioural impairment and not the seizure per se. Systematic characterization of local blood flow and tissue oxygen levels following focal seizures revealed a period of severe hypoperfusion/hypoxia (~50% reduction in blood flow, pO2 < 10mmHg) that often lasted over an hour in several rodent seizure models and persons with epilepsy. Cyclooxygenase-2 and L-type calcium channels were identified as key molecular targets that mediate local vasoconstriction. Further interrogation of the mechanism determined that the canonical cyclooxygenase-2 signalling cascade, involving oxygenation of arachidonic acid to prostaglandins, was not responsible for this phenomenon. Instead, oxygenation of the endocannabinoid, 2- arachidonoylglyerol, which yields novel prostaglandin glycerol esters, was identified as the primary pathway mediating severe postictal hypoperfusion/hypoxia. Thus, disrupting cyclooxygenase-2 function or L-type calcium channel activity prevented the expression of this pathological event. Inhibition of either target, which blocked hypoxia but not seizures, revealed that severe postictal hypoperfusion/hypoxia is responsible for postictal memory deficits and Todd’s paresis. These findings may extend to several negative features of epilepsy including other acute behavioural impairments, sudden unexpected death in epilepsy, anatomical abnormalities, epileptogenesis, and interictal comorbidities. This research identifies a novel, testable theory for epilepsy which places severe postictal hypoperfusion/hypoxia as a causal mechanism behind epilepsy pathology and behavioural dysfunction. Most importantly, the molecular targets identified herein may ultimately lead to new therapies for untreated aspects of epilepsy and improve quality of life.
Thoughts on Affect: Reading Harold Innis, Donald Creighton, and Sylvia Van Kirk

subject: Fur Trade
subject: Historiography

description: This thesis focuses on three fur trade history texts: Harold Innis’s The Fur Trade in Canada, Donald Creighton’s The Empire of the St. Lawrence, and Sylvia Van Kirk’s Many Tender Ties. Using the works and concepts of theorists Donna Haraway, Gilles Deleuze and others, it is argued that each text, through its subject matter, reveals an element of more-than-humanness. The condition of more-than-human calls into question the conception of a human as a stable and singular subject, and the pre-eminent position of the lone human agent within the study of history. This post-humanist analysis allows for a re-reading of these fur trade histories by challenging how the intentional human agent in history is perceived and reproduced in text. In order to initiate a re-reading, each text is re-cast into a different genre in order to prompt the reader into thinking about these history texts in radically different terms. By accentuating the literary nature by which these three historical works operate, the inherent aesthetic and ethical weaknesses imbued in history’s representation and production of the subject and agency are revealed. By putting forth the Deleuzian conception of repetitional thinking as an alternative, this thesis hopes to subvert and ease the grasp of representational thinking on the study of history.

We provide an application to weighted projective schemes.

description: In this study, we examine the social networking practices of the 100 largest nonprofit organizations in the United States. More specifically, we develop a comprehensive classification scheme to delineate these organizations' use of Facebook as a stakeholder engagement tool. We find that there are 5 primary categories of Facebook "statuses", which can be aggregated into three key dimensions - "information", "community", and "action". Our analysis reveals that, though the "informational" use of Facebook is still significant, nonprofit organizations are better at using Facebook to strategically engage their stakeholders via "dialogic" and "community-building" practices than they have been with traditional websites. The adoption of social media seems to have engendered new paradigms of public engagement.

description: In the present thesis, I propose that the dramatist Sabina Berman subverts Mexican patriarchal archive through performativity in two of her productions: El suplicio del placer (1973) and Entre Pancho Villa y una mujer desnuda (1993). In order to achieve this objective, I have applied the ideas of Diana Taylor. Taylor´s theory has been employed to emphasis how certain films and canonic literary texts produced posterior to the Mexican Revolution can be examined as archive. Moreover, I have used the concept of ideology, coined by Louis Althusser, to demonstrate how the archive follows a paternalistic dogma. Lastly, supported by the theoretical approaches of Judith Butler and Richard Schechner, it was possible to delimit how the archive can be contested. However, gender transgressions usually depend on the social class to which the individual belongs.

Molecular and cellular characterization of the CYP26b1-null limb phenotype
Creators: name: Dranse, Helen
Publisher: name: University of British Columbia
Year: 2011

description: Cyp26b1, a retinoic acid (RA)-metabolizing enzyme, is expressed in the developing limb bud and Cyp26b1-/- mice present with severe early limb defects characterized by truncated skeletal elements and oligodactyly. These malformations have previously been attributed to a patterning defect; however, recent reports suggest that RA is dispensable for limb patterning. In this study, we examined the role of endogenous retinoid signalling in skeletogenesis using Cyp26b1-/- mice and transgenic mice in which Cyp26b1 is conditionally deleted under control of the Prrx1 promoter beginning at ~E9.5 (Prrx1Cre⁺/Cyp26b1fl/fl). We found that the limb phenotype in Prrx1Cre⁺/Cyp26b1fl/fl mice was less severe than Cyp26b1-/- animals and that a difference in retinoid signalling contributed to the difference in phenotypes. We systematically examined the role of RA signalling in chondrogenesis and found that Cyp26b1-/- cells are maintained at a pre-chondrogenic stage, exhibit reduced chondroblast differentiation, and exhibit a modest impact on chondrocyte hypertrophy. Furthermore, Cyp26b1-/- mesenchyme exhibited an increase in the expression of Scleraxis and other tendon markers, indicating that increased retinoid signalling in the limb maintains the ability of precursor cells to commit to other mesenchymal lineages. We conclude that RA signalling negatively impacts chondrogenesis before the onset of Ihh signalling, and has a positive impact on chondrocyte hypertrophy. This suggests that the limb phenotype in Cyp26b1-/- animals results from defects in the execution of a patterning program, and not so much in the patterning program itself.
Integrating Sedimentology, Sequence Stratigraphy and Mineralogy to Evaluate Controls on Hydrocarbon Accumulation and Production in the Bakken Formation of Southeast Saskatchewan

Subjects: subject: Geology

description: The Bakken Formation is a prolific oil reservoir within the Williston Basin and has been the focus of extensive horizontal drilling in recent years. The study area encompasses the Viewfield Pool in SE Saskatchewan, host to over 1.3 billion barrels of original oil in place. The stratigraphy and depositional settings of the Bakken Formation in this area are poorly understood, despite a growing body of literature and the relatively high resolution geological dataset. Additionally, the Viewfield Pool serves as an excellent case study for examining a conventional hydrocarbon trap in an unconventional hydrocarbon reservoir. The Bakken Formation was deposited on a low gradient shallow marine ramp within a shallow epi-continental sea. The Middle Bakken Member consists mainly of bioturbated and dolomitized siltstones, while the Upper and Lower Bakken member consist of organic rich mudstones. A reinterpretation of the sequence stratigraphy shows five distinct systems tracts are represented in the Bakken Formation, and a total of seven unique lithofacies are present. These lithofacies present evidence of a wave dominated shoreline during regressive phases and a tidally influenced shoreline during transgressive phases. A comprehensive mineralogical model is derived from X-Ray fluorescence, X-Ray diffraction, and point counting. High resolution mineralogical data reveals subtle sedimentary heterogeneity not previously documented, strengthening the sequence stratigraphic interpretation. An inverse correlation is present between porosity and dolomite + calcite content. A positive correlation is present between both porosity and permeability, and quartz content. Detailed reservoir characterization reveals higher rates of hydrocarbon production is associated with increased net pay, low initial water cuts, high quartz content and reduced intensity of calcite cementation.

description: Quarkonia have been studied in different collision system and energy in order to understand the effects of the hot and dense medium created in heavy-ion collisions. CMS is well suited to measure quarkonia decays to muons given the muon identification and charged particle tracking capability. We report here prompt, non-prompt J/ψ, and Υ production measured by the CMS experiment in pp collisions at \sqrt{s}=7 TeV. In addition, the J/ψ and Υ production in PbPb at \sqrt{s_{NN}}=2.76 TeV and pp collisions at the same per nucleon energy are measured and compared. Prompt and non-prompt J/ψ contributions are separated for the first time in heavy-ion collisions, as is the ground from the excited states in the Υ family. Suppression in PbPb at \sqrt{s_{NN}}=2.76 TeV is quantified for prompt J/ψ, B->J/ψ, and Υ(1S), as well as the relative suppression of Υ(2S+3S) compared to Υ(1S).

description: Convection plays an essential role in the emerging intensity for many stars that will be observed by Gaia. Convective-related surface structures affect the shape, shift, and asymmetry of absorption lines, the phocentric and photometric variability causing bias in Gaia measurements. Regarding the importance of Gaia mission and its goals, it is mandatory to have the best models of the observed stars. 3D time-dependent hydrodynamical simulations of surface convection are crucial to model the photosphere of late type stars in a very realistic way. These simulations are an important tool to correct the radial velocities and better estimates the parallaxes and photometric variability.

description: The article enlightens the issue of an intellectual method for optimal control of high-quality drying of thermolabile products in a microwave installation.Mathematical and computer models were compiled by multi-stage system thinking and analysis, and their adequacy was established with a probability of 0.95. The optimal control mode allows you to maintain the temperature of the material in the specified limit and produce a high-quality dried product. A system of microprocessor-based discrete automatic control of a microwave dryer is proposed to enable the heater to be switched on at various specified ranges with a decreasing frequency of material temperature changes, where the length of discrete heating oscillations at the end of the process is ten times less than the initial one.

description: This thesis examines the role and influence of Canadian manufacturers and executives working for the Canadian government, known as the dollar-a-year men, in mobilizing the Canadian economy for war production. Based chiefly on primary source research this thesis examines contracting methods, the bureaucratic structure of the Department of Munitions and Supply, and the degree to which the Department reacted to events. This thesis demonstrates that the dollar-a-year men’s strategy for industrial mobilization was initially focused on maximizing production at almost any cost, and only started focusing on cost efficiency in late 1942 and early 1943. It is also demonstrated that the current historiography is lacking and that C.D. Howe played a far different role than the historiography describes.
The complete census of optically selected AGNs in the Coma Supercluster: the dependence of AGN activity on the local environment

description: To investigate the dependence of the occurrence of active galactic nuclei (AGNs) on local galaxy density, we study the nuclear properties of ~5000 galaxies in the Coma Supercluster whose density spans 2 orders of magnitude from the sparse filaments to the cores of the rich clusters. We obtained optical spectra of the nuclei of 177 galaxies using the 1.5m Cassini telescope, which are added to the 4785 spectra available from SDSS (DR7) to fill-in the incomplete coverage by SDSS of luminous galaxies. We perform a spectral classification of the nuclei of galaxies (with a completeness of 98% at r<17.77), classifying the nuclear spectra in six classes: three of them (SEY, sAGN, LIN) refer to AGNs and the remaining three (HII, RET, PAS) refer to different stages of starburst activity. To perform such classification, we use the WHAN diagnostic, after correcting Halpha by 1.3 A for underlying absorption. We find that 482 (10%) of 5027 galaxies host an AGN: their frequency strongly increases with increasing luminosity of the parent galaxies, such that 32% of galaxies with Log(i-Lum)<10.2 (Solar) harbor an AGN at their interior. In addition to their presence in luminous galaxies, AGNs are also found in red galaxies with < 1.15 \pm 0.15 mag. The majority of SEY and sAGN (strong AGNs) are associated with luminous late-type (or S0a) galaxies, while LIN (weak AGNs) and RET ("retired"), are mostly found among E/S0as. The number density of AGNs, HII region-like, and retired galaxies is found to anti-correlate with the local density of galaxies, such that their frequency drops by a factor of two near the cluster cores, while the frequency of galaxies containing passive nuclei increases by the same amount towards the center of rich clusters. The dependence of AGN number density on the local galaxy density is greater than the one implied by morphology segregation alone.

description: High quality diet is integral for maintaining health and preventing chronic diseases. Diet quality has many determinants that interact across the intra-individual, inter-individual, physical environment, and policy levels of influence. This thesis presents a novel method to create Canada’s Food Guide serving equivalents in the Canadian Diet History Questionnaire II nutrient database for the purpose of deriving the Canadian Healthy Eating Index (C-HEI). The C-HEI was used as a measure of diet quality in an analytical study investigating the potential independent and joint effects of the neighbourhood food environment and neighbourhood socioeconomic status on diet quality of adults living in Calgary, Alberta. The density of all neighbourhood food destinations, but not neighbourhood socioeconomic status independently or jointly with neighbourhood food destination density, plays a small role in diet quality of Calgary adults. With additional research, these findings may help inform population level interventions aimed at improving diet quality for all Canadians.

description: Given an integer $t\ge 1$, a rational number $g$ and a prime $p\equiv 1({\rm mod} t)$ we say that $g$ is a near-primitive root of index $t$ if $ν_p(g)=0$, and $g$ is of order $(p-1)/t$ modulo $p$. In the case $g$ is not minus a square we compute the density, under the Generalized Riemann Hypothesis (GRH), of such primes explicitly in the form $ρ(g)A$, with $ρ(g)$ a rational number and $A$ the Artin constant. We follow in this the approach of Wagstaff, who had dealt earlier with the case where $g$ is not minus a square. The outcome is in complete agreement with the recent determination of the density using a very different, much more algebraic, approach due to Hendrik Lenstra, the author and Peter Stevenhagen.

A Monte Carlo simulation framework for modelling Artis Zeego CBCT using GATE.

Publisher: name: Zenodo

description: For task-specific images taken for minimally invasive interventions, limiting the acquisi- tion angle or reducing the number of projections of the cone-beam CT (CBCT) system can lead to efficient minimization of patient dosage. Geant4 application for tomographic emission (GATE) is dedicated to modelling of medical imaging systems. It facilitates Monte Carlo (MC) simulation through an easy-to-use script code and does not require prior C++ knowledge. For accurate CT projections, the material and geometry specifica- tions of the filter, collimator, source and the detector are modeled as close as possible to an interventional CBCT scanner (Artis zeego, Siemens Healthineers, Forchheim, Germany). Simulations were performed using a patient realistic XCAT phantom, which depicts the cardio-torso region of the body and a water cylinder whose simulation results were com- pared to actual measurement results obtained from the Artis zeego CBCT scanner. The simulation runtime was reduced from multiple weeks on one CPU down to 2-3 days by dividing the simulation into 500 smaller tasks and parallely executing them on EGI’s (Europen Grid Infrastructure) computer cluster through the Gate-Lab platform. GATE Simulation results showed acceptable similarity with the Artis zeego measurement re- sults. The proposed GATE framework enables accelerated simulation of CT projections of arbitrary source-detector orbits and can incorporate patient anatomy.

description: We consider possible exotic ground states of quantum spin ice as realized in rare earth pyrochlores. Prior work in Phys. Rev. Lett. 108, 037202 introduced a gauge mean field theory (gMFT) to treat spin or pseudospin Hamiltonians for such systems, reformulated as a problem of bosonic spinons coupled to a U(1) gauge field. We extend gMFT to treat the most general, nearest neighbor exchange Hamiltonian, which contains a further exchange interaction, not considered previously. This term leads to interactions between spinons, and requires a significant extension of gMFT, which we provide. As an application, we focus especially on the non-Kramers materials Pr2TM2O7 (TM=Sn, Zr, Hf, and Ir), for which the additional term is especially important, but for which an Ising-planar exchange coupling discussed previously is forbidden by time-reversal symmetry. In this case, when the planar XY exchange is unfrustrated, we perform a full analysis and find three quantum ground states: a U(1) quantum spin liquid (QSL), an antiferro-quadrupolar ordered state and a non-coplanar ferro-quadrupolar ordered one. We also consider the case of frustrated XY exchange, and find that it favors a pi-flux QSL, with an emergent line degeneracy of low energy spinon excitations. This feature greatly enhances the stability of the QSL with respect to classical ordering.

description: British efforts to aid the Soviet Union in the early months of the war in the East are underexplored and simplified in the historiography of Allied supply to Russia during the Second World War. In fact, British leaders recognized within weeks of the German invasion that the Eastern Front was the most important front in the war against Nazi Germany and that the Soviets were likely to continue to resist for a long time. Britain then became increasingly committed to supplying the Soviets with material aid. Given the difficulties involved, and Soviet uncooperativeness, British aid prior to the Moscow Supply Conference was substantial and relatively swift. The expansion of aid into a large scale effort, later established on a lend-lease basis, had its origins in the evolution of British assessments and priorities over the summer of 1941.

description: Consumer-grade cameras can be programmed by technical users with an interest in photography, but currently the potential is still being investigated. We explore some of the capabilities available using programmable cameras through the example of capturing what we term a four-dimensional (4D) volume of image data. Having access to a 4D volume of image data allows for the creation of photographs that are visually interesting, but also technically challenging to work with. We deal with the inherent complexity by building tools using computer vision and image processing techniques both at the computer desktop software level as well as inside the camera itself. Our intention is to assist artists and photographers to manage this inherent complexity. The assistance we provide is evaluated by some artists and photographers through a user study. Now that programmable cameras have become available, our work shows how embedding image processing inside a consumer camera along with other computer vision tools can facilitate photographers’ creative possibilities.

description: The Beam Emission Spectroscopy (BES) turbulence diagnostic on MAST is to be upgraded in June 2010 from a 1D trial system to a 2D imaging system (8 radial \times 4 poloidal channels) based on a newly developed APD array camera. The spatial resolution of the new system is calculated in terms of the point spread function (PSF) to account for the effects of field-line curvature, observation geometry, the finite lifetime of the excited state of the beam atoms, and beam attenuation and divergence. It is found that the radial spatial resolution is ~ 2-3 cm and the poloidal spatial resolution ~ 1-5 cm depending on the radial viewing location. The absolute number of detected photons is also calculated, hence the photon noise level can be determined

description: The ability to recruit and expand new blood vessels is an essential component of tumour growth. Hence, the main goal of this study was to determine whether we could prevent the growth of bone metastases by blocking angiogenesis via the use of the vascular disrupting agent (VDA), DMXAA, either alone, or used in combination with the pan-PI3K inhibitor, GDC-0941. DMXAA, an agent of the flavonoid class, has been shown to disrupt the tumour vasculature in a number of model systems by selectively inducing apoptosis in tumour vascular endothelial cells. Since the PI3K/Akt pathway has been shown to increase cell survival, growth, and proliferation, we hypothesized that by inhibiting a major anti-apoptotic mechanism, a PI3K inhibitor, we would be able to increase the anti-vascular effects of a VDA within bone metastasis xenografts. Contrary to what we expected, DMXAA, either alone or in combination with GDC-0941, had no statistically significant on bioluminescence of established metastases while bioluminescence of subcutaneous tumours was severely affected. Our studies provide a possible explanation for the failure of DMXAA in human clinical trials.
Premature infants' nighttime awakening and their mothers' attachment styles and bedtime behavior
Creators: name: Ali, Reem
Publisher: name: University of British Columbia
Year: 2010

description: Infants’ sleep problems, especially, nighttime awakenings, are common concerns of parents and may have developmental implications for infants, particularly infants born prematurely. Between one quarter and one third of all children aged six months to five years of age experience sleeping problems. Many factors have been associated with the development of these problems, although none has been shown to be causal. Although theorists have hypothesized that insecure attachment between a mother and her child may lead to intense maternal involvement at bedtime (e.g., active physical comforting), which may be linked to the infant’s inability to develop sleep self-initiation skills, mothers’ styles of attachment with their infants, particularly an anxious style, have not been researched. France and Blampied’s model of infant sleep was used as the guiding framework to examine relationships between mothers’ attachment and bedtime behaviour and premature infants’ sleep. Using a cross-sectional design, data were collected from a community-based sample of 105 mothers of premature infants aged 5-6 months (gestationally corrected age). Boys represented 61% of the sample and 63% of the infants were first-born children. The main outcome measures were infants’ nighttime awakenings (frequency and duration) and mothers’ perceptions of the quality of their infants’ sleep. The mothers reported that 55% of their children had sleep problems (17% were considered serious). The reported mean frequency of awakening was 2.1 times per night and the mean duration was 45.7 minutes. Preterm infants’ nighttime awakening was associated with their mothers having an anxious style of attachment and intense involvement at bedtime. The mother’s style of attachment (anxious) and a maternal history of sleep problems were predictors of the duration of infants’ nighttime awakening. Intense maternal involvement and the infant’s birth order were significant predictors of the infants’ frequency of nighttime awakenings. This study directs healthcare providers to focus on maternal factors such as having an anxious style of attachment and over involvement in bedtime settling when assessing infants’ sleep problems. More research is warranted to explain the mechanisms of these associations and to determine whether they are causal in nature.

ILK represses E-cadherin expression by regulating PARP-1 binding to the Snail promoter
Creators: name: McPhee, Timothy Ryan
Publisher: name: University of British Columbia

description: The loss of E-cadherin, a critical component of the adherence junctions, is implicated in the metastasis of carcinomas and correlates with tumour grade. Here we show that in PC3 cells loss of Integrin-Linked Kinase (ILK), AKT/PKB or Snail-1, results in the re-expression of E-cadherin at both the mRNA and protein level. We have previously shown that ILK is capable of transcriptionally regulating the E-cadherin repressor Snail-1, via a 65-bp ILK responsive element in the 5' promoter termed the Snail-1 ILK Responsive Element (SIRE). Using a SIRE oligonucleotide we identified three candidate SIRE binding proteins that demonstrate differential binding due to loss of ILK: Poly(ADP-ribose) polymerase-1 (PARP-1), Methyl-CpG domain binding protein 5 (MBD-5) and a fragment of Chromodomain-helicase-DNA-binding protein 8/Helicase with SNF2 domain 1 (CHD-8/HELSNF1). PARP-1, which bound the SIRE in the presence, but not the absence of ILK was further characterized in this study. Like ILK, AKT and Snail-1, PARP-1 siRNA treatment results in the upregulation of E-cadherin. Inhibition of the ADP-ribose polymerase activity of PARP-1 partially blocks the upregulation of E-cadherin in ILK siRNA treated cells. This suggests a mechanism in which ILK has a role in maintaining PARP-1 in an inactive state, repressing expression of E-cadherin. We demonstrate that in Scp2 cells ILK overexpression results in the induction of Snail-1 expression. We suggest a model in which ILK regulates E-cadherin by regulating PARP-1 enzymatic activity. The regulation of PARP-1 activity modulates its ability to bind to the Snail-1 promoter.

description: The article describes a hybrid algorithm for tuning parameters of a neural network based on sigma-pi neurons. The process of controlling an algorithm based on a hybrid neural network is considered. The use of an integrated training approach for neural networks built on the basis of sigma-pi neurons makes it possible to train them in the time required to configure the neural network to solve an applied problem. The possibility of using a sigma-pi network to estimate the parameters of the information transmission channel based on the analysis of the spectrum of the reflected sounding signal is considered. To form a training and test network sample, a description of the developed device for analyzing wire communication lines is given.
The Role of Social Support in Children with Attention-Deficit/Hyperactivity Disorder: Promoting Resilience in an At-Risk Population

description: Children with Attention-Deficit/Hyperactivity Disorder (ADHD) face significantly increased risk for poor outcomes across domains; however, not all children with ADHD experience poor outcomes (Lee et al., 2008; Owens et al., 2009). Resilience perspectives can provide a valuable avenue through which to explore the factors and processes contributing to more positive trajectories among children with ADHD. The current study took a resilience approach to investigate the role of a potential protective factor, perceived social support, in promoting emotional well-being among children with ADHD. Social support has long been recognized as an important factor in promoting well-being among both typically-developing and at-risk populations (e.g., Cohen & Wills, 1985; Demaray et al., 2005), but has yet to be explored in this capacity within the ADHD population. This study specifically examined how school-age children with ADHD perceive support from key individuals in their lives (e.g., parents, teachers, peers, other adults) and the relationships between perceived social support and various indicators of emotional well-being (internalizing problems, self-concept). Additionally, main versus buffering models of social support were explored by evaluating the relationships of social support and emotional adjustment in the context of lower or higher social preference status. A total of 55 children ages 8 to 11 with ADHD-C or ADHD-HI and their parents participated in this study. Overall, results indicate positive and moderate associations between perceived social support and several aspects of self-concept, with parent and classmate support most consistently associated with these outcomes. Results further support a main effect model of perceived social support, with no interaction detected between social support and social preference status. Results of this study are discussed within the context of applying a resilience lens to the study of ADHD, and implications for both research and practice are discussed.

description: A review of the results of the Near-IR S0 galaxy Survey (NIRS0S) is presented. NIRS0S is a magnitude (mB 12.5 mag) and inclination (< 65o) limited sample of 200 nearby galaxies, mainly S0s. It uses deep Ks -band images, typically reaching a surface brightness of 23.5 mag arcsec^(-2) . Detailed visual and photometric classifications were made, for the first time coding also the lenses in a systematic manner. As a comparison sample, a similar sized spiral galaxy sample with similar image quality was used. The main emphasis were to study whether the S0s are former spirals in which star formation has been ceased, and also, how robust are bars in galaxies. Based on our analysis the Hubble sequence was revisited: following the early idea by van den Bergh we suggested that the S0s are spread throughout the Hubble sequence in parallel tuning forks as spirals (S0a, S0b, S0c etc.). This is evidenced by our improved bulge-to-total (B/T) flux ratios, reaching as small values as typically found in late-type spirals. The properties of bulges and disks in S0s were found to be similar to those in spirals. Also, the masses and scale parameters of the bulges and disks were found to be coupled. Bars were found to be fairly robust both in S0s and spirals, but inspite of that bars might evolve significantly within the Hubble sequence.

description: This research examined how immigration consultancy firms (ICFs) affect immigrants’ settlement process and, why potential immigrants rely on ICFs to deal their immigration application. Data for this research were collected in Calgary through semi-structured interviews and analysis of secondary data. This research explored two main findings. Firstly, this research revealed that ICFs partially influenced potential immigrants’ selection of landing cities in Canada, with the selective information they provided to potential immigrants. Furthermore, ICFs influence secondary migration from other Canadian cities to Calgary. Secondly, ICFs broke the chain of migration networks changing the model of immigration from one that builds and expands social networks to one that breaks and replaces them. This research also analyzed the situation and political background surrounding the rise of ICFs. This exploration demonstrated that private immigration companies gradually replaces the role of social networks in immigration and their negative results such as fraud and secondary migration.
