description: This comprehensive examination of 132 picture books originally published by Canadian publishers in 2017, and written and/or illustrated by at least one creator living in Canada, offers qualitative and quantitative findings that demonstrate patterns and themes in relation to number of titles, authors, illustrators, characters, genres, audiences, and readability characteristics, while addressing particular elements of Dresang’s (1999) notion of Radical Change. Books were identified from multiple sources with results compared to a previous study (Author 3), demonstrating a marginal increase of titles since 2015 where 120 books were identified, and a continued increase from 2005 where 57 books were identified. Of particular note in the current sample were the 13 books created by Indigenous authors and/or illustrators and presenting Canadian Indigenous content and perspectives, calculated at 9.8 % of the study sample, compared to previous results where books by Indigenous authors and/or illustrators comprised 3.5 % of the sample in 2005 and 10% in 2015. These findings, and other patterns, themes and possible trends, are suggested as underpinnings for future research involving further changes in the field of Canadian children’s literature in education as well as further research into reader response regarding contemporary titles. While this paper does address aspects of diversity present in this study sample, a second article disseminates detailed findings related to representations of ethnicity. .

description: The LIFE AGROWETLANDS II - LIFE15 ENV/IT/000423 project, funded under the LIFE 2014/2020 Programme - Environment, aimed to improve the management of two resources essential for life and strategic for agriculture: water and soil. Water is commonly considered a renewable resource, but if this is true in a wide context, it is not so at a local scale regarding quality, or through centuries. The soil, on the other hand, is anyways considered a non-renewa-ble resource. Concerning the agricultural practices that affect the conservation of water and soil, and in particular irrigation, the project developed a tool to support irrigation management on saline soils. The project also identifies precision agriculture and its developments as a crucial tool for the sustainability of agriculture itself in the coming years.
Agrarian repair : agriculture, race and accumulation in contemporary Canada and South Africa
Creators: name: Sommerville, Melanie
Publisher: name: University of British Columbia
Year: 2019

description: This dissertation explores certain agricultural investment projects emerging early in the new millennium which I term ‘agrarian repair’ projects. Proponents of these projects present them as binding together two distinct ‘fixes’. First, they seek to repair processes of capital accumulation and value preservation, always uncertain but freshly destabilized by the 2007/8 financial crisis. Second, they attempt to repair histories of colonial and racial injustice, often codified as resulting in and from a particular group’s historical ‘exclusion’ from agriculture and consequently larger national economies. I examine ‘agrarian repair’ projects at two sites, one in Canada and one in South Africa, where financial investors partnered with racialized, marginalized communities to establish large scale agricultural investment ventures. In Canada, One Earth Farms established a massive corporate grain, oilseeds and cattle farm engaging First Nations in the prairie provinces. In South Africa, the Futuregrowth Agri-Fund implemented investment models involving African communities in the commercial fruit sector across the country. I trace the historical origins of the projects, situating them in two concurrent transitions unfolding in their respective national settings: one in the organization of the agrarian economy, the other in the orientation of the nation-state towards a liberal democratic ‘reconciliatory’ dispensation. I detail the specific logics, modalities, and mechanics employed by the ‘agrarian repair’ projects, reflecting on how they can advance understandings of financialized racial capitalism and its operations at the settler colonial agrarian interface. I assess the projects’ capacity to deliver on their purported fixes, showing that agriculture neither proves to be the stable financial provider that investors expect, nor do the projects deliver their anticipated social results. Benefits for the racialized communities engaged are uneven at best, while the projects actively exploit not only settler colonial and racial legacies but also contemporary redress efforts, generating new advantages and valuation channels for investors. The research lends insights into how colonial and racialized histories and reparative movements are mobilized and monetized in contemporary agricultural projects. This allows me to begin outlining a larger schema of reparative capitalism, whereby capitalism incorporates its critiques – here about its colonial and racial past – as new sites of accumulation.

description: Bipolarity in proto-planetary and planetary nebulae is associated with events occurring in or around their cores. Past infrared observations have revealed the presence of dusty structures around the cores, many in the form of disks. Characterising those dusty disks provides invaluable constraints on the physical processes that govern the final mass expulsion of intermediate-mass stars. We focus this study on the famous M2-9 bipolar nebula, where the moving lighthouse beam pattern indicates the presence of a wide binary. The compact and dense dusty core in the center of the nebula can be studied by means of optical interferometry. M2-9 was observed with VLTI/MIDI at 39-47 m baselines with the UT2-UT3 and UT3-UT4 baseline configurations. These observations are interpreted using a dust radiative transfer Monte Carlo code. A disk-like structure is detected perpendicular to the lobes and a good fit is found with a stratified disk model composed of amorphous silicates. The disk is compact, 25$\times$35 mas at 8$\rm μm$, and 37$\times$46 mas at 13$\rm μm$. For the adopted distance of 1.2 kpc, the inner rim of the disk is $\sim$15 AU. The mass represents a few percent of the mass found in the lobes. The compactness of the disk puts strong constraints on the binary content of the system, given an estimated orbital period 90-120yr. We derive masses of the binary components between 0.6--1.0M$_{\sun}$ for a white dwarf and 0.6--1.4M$_{\sun}$ for an evolved star. We present different scenarios on the geometric structure of the disk accounting for the interactions of the binary system, which includes an accretion disk as well.

description: We collected notes and simple estimates about putative narrow nucleon N*(1685) - the candidate for the non-strange member of the exotic anti-decuplet of baryons. In particular, we consider the recent high precision data on eta photoproduction off free proton obtained by the Crystal Ball Collaboration at MAMI. We show that it is difficult to describe peculiarities of these new data in the invariant energy interval of W ~ 1650-1750 MeV in terms of known wide resonances. Using very simple estimates, we show that the data may indicate an existence of a narrow N*(1685) with small photocoupling to the proton.

description: We show how to construct low energy solutions to the Randall Sundrum II (RSII) model using an associated AdS_5-CFT_4 problem. The RSII solution is given in terms of a perturbation of the AdS-CFT solution, with the perturbation parameter being the radius of curvature of the brane metric compared to the AdS length \ell. The brane metric is then a specific perturbation of the AdS-CFT boundary metric. For low curvatures the RSII solution reproduces 4d GR on the brane. The leading correction is from local higher derivative curvature terms. The subleading correction is derived from similar terms and also the dual CFT stress tensor. Recently AdS-CFT solutions with 4d Schwarzschild boundary metric were numerically constructed. We modify the boundary conditions to introduce the RSII brane, and use elliptic numerical methods to solve the resulting boundary value problem. We construct large RSII static black holes with radius up to ~ 20 \ell. For large radius the RSII solutions are indeed close to the associated AdS-CFT solution. In this case the local curvature corrections vanish, and we confirm the leading correction is given by the AdS-CFT solution stress tensor. We also follow the black holes to small radius << \ell, where as expected they transition to a 5d behaviour. Our numerical solutions indicate the RSII black holes are dynamically stable for axisymmetric perturbations for all radii.

description: The abilities to experience and understand another person’s feelings (empathy), to successfully cope with stress (resilience), and to harness personal skills (psychological strengths) are dynamic qualities that may be associated to an adolescent’s perception of care from others (i.e., family, friends, school staff, and significant others). Although the association of these different social sources have been studied independently, it has yet to be elucidated which of these sources is most highly associated to the presentation of these three qualities. For this study, high school students from a northern community completed a series of online questionnaires. A series of hierarchical regressions showed each source of care accounted for unique variance in the presentation of resilience and strengths, with perceived care from school staff and family accounting for the greatest variance, emphasizing the equal importance of examining the school and home environment. Further research is needed to understand how teachers and the school culture are associated with personal growth. Keywords: adolescent growth, resilience, psychological strengths, positive psychology, social support Les capacités de ressentir et de comprendre les sentiments d’autrui (l’empathie), de bien gérer le stress (la résilience) et d’exploiter ses compétences personnelles (forces psychologiques) sont des qualités dynamiques qui peuvent être associées à la perception qu’ont les adolescents des soins dispensés par les autres (c.-à-d., la famille, les amis, le personnel de l’école et l’être cher). Si l’association de ces différentes sources sociales a été étudiée indépendamment pour chacune d’elles, il reste à comprendre laquelle est la plus fortement liée aux trois qualités décrites ci-haut. Dans le cadre de cette étude, des élèves du secondaire provenant d’une communauté du nord ont complété une série de questionnaires en ligne. Une série de régressions hiérarchiques a démontré que chaque source de soins expliquait une variance unique dans la présentation de la résilience et des forces. Les soins perçus de la part du personnel de l’école et de la famille représentent la plus grande variance, ce qui souligne l’importance de se pencher tant sur le milieu scolaire que le milieu familial. Il faudrait mener des recherches plus poussées pour comprendre dans quelle mesure les enseignants et la culture scolaire sont associés à l’épanouissement personnel.

description: Cosmic ray anomalies observed by PAMELA and Fermi-LAT experiments may be interpreted by heavy (TeV-scale) dark matter annihilation enhanced by Sommerfeld effects mediated by a very light (sub-GeV) U(1)_X gauge boson, while the recent direct searches from CoGeNT and DAMA/LIBRA experiments may indicate a rather light (\sim 7 GeV) dark matter with weak interaction. Motivated by these apparently different scales, we consider a gauge mediated next-to-the minimal supersymmetric standard model (NMSSM) entended with a light U(1)_X sector plus a heavy sector (\bar H_h,H_h), which can provide both a light (\sim 7 GeV) and a heavy (TeV-scale) dark matter without introducing any ad hoc new scale. Through the Yukawa coupling between H_h and the messager fields, the U(1)_X gauge symmetry is broken around the GeV scale radiatively and a large negative m_S^2 is generated for the NMSSM singlet S. Furthermore, the small kinetic mixing parameter between U(1)_X and U(1)_Y is predicted to be θ\sim 10^{-5}-10^{-6} after integrating out the messengers. Such a light dark matter, which can have a normal relic density from the late decay of the right-handed sneutrino (assumed to be the ordinary next-to-the lightest supersymmetric particle and thermally produced in the early universe), can serve a good candidate to explain the recent CoGeNT and DAMA/LIBRA results.

Methodological Options for Reading a Narrative of Collaboration Online in Canadian Education
Creators: name: Ippolito, John
Publisher: name: Alberta Journal of Educational Research
Year: 2020

description: This study considers three methodological orientations for reading the narrative of collaboration taken root in contemporary discussions around publicly funded education in Canada. It looks through and beyond conflict theory and an archaeological historical approach and turns to a discursive method well suited to close analysis of recorded, text-based exchanges. Selecting discursive psychology and conversation analysis as preferred interpretive tools, it samples an exchange from an institutional interaction between a researcher, a teacher, and two parents in an online discussion forum. The analysis highlights the multiplicity of agendas and work generated across stakeholders by what is ostensibly one shared goal. Key words: minority parents, Canadian schools, online, discursive psychology, conversation analysis Cette étude examine trois orientations méthodologiques pour interpréter le récit sur la collaboration qui s’est enraciné dans les discussions contemporaines portant sur l’éducation publique au Canada. L’étude part de la théorie des conflits et regarde au-delà de celle-ci, passe par une approche historique archéologique pour se tourner vers une méthode discursive bien adaptée à une analyse approfondie des échanges textes enregistrées.d Ayant privilégié la psychologie discursive et l’analyse des conversations comme outils d’interprétation, l’étude se penche sur un échantillon consistant en une interaction institutionnelle entre un chercheur, un enseignant et deux parents sur un forum de discussion en ligne. L’analyse fait ressortir la multiplicité de programmes et le travail généré par les parties prenantes vers ce qui est présenté comme étant un objectif partagé. Mots clés: parents minoritaires; écoles canadiennes; en ligne; psychologie discursive; analyse des conversations

Sustainable transport safety : applying updated community-based macro-level collision prediction models for Kelowna using manual and automated tools
Creators: name: Garg, Vipul
Publisher: name: University of British Columbia
Year: 2019

description: Traffic-related injuries and fatalities are considered the ninth worst global epidemic, exerting an enormous social and economic burden across countries. Transportation planners and engineers are now proactively considering safety in the transportation planning process to improve the overall safety of the transportation network. Macro-level collision prediction models (CPMs) have been identified as a reliable planning-level decision-support tool to inform safety conscious planning. However, the success or failure of these models in one spatial environment depends on the quality of the dataset, appropriate model functional form, and time frame of model development and application. As road parameters, network design, regional socio-demographic and size of geographical aggregation unit changes over time, updating these models becomes necessary. This research reviewed the literature corresponding to the development and application of community-based macro-level CPMs. Based on the insights gained from the literature, community-based macro-level CPMs were updated for Kelowna using the negative-binomial (NB) and full Bayesian (FB) modelling techniques, and IHSPM model development module. The updated CPM results are in good agreement with past research that developed the original Kelowna models. One new and significant result in updating the CPMs, due to the availability of new data, was the decreased collisions with the increased proportion of roundabouts, a result seen previously only in micro-level collision prediction models. The updated CPMs were then applied to present-day Kelowna neighbourhoods, to identify and rank collision-prone zones (CPZs). A series of macro-level collision modification factors (CMFs) was developed to examine the impact of different exposure, socio-demographic, transportation demand management and network-related countermeasure strategies on the safety of a traffic analysis zone. Moreover, as the development of these models is a cumbersome, semi-manual, and time-consuming process that requires a sound knowledge of spatial analysis, and data analysis tools, this thesis assessed an online road safety planning tool 'IHSPM' that automates the development and application of community-based macro-level CPMs models, developed to date at STS lab.

description: We present a homogeneous survey of the CN and CH bandstrengths in eight Galactic globular clusters observed during the course of the Sloan Extension for Galactic Understanding and Exploration (SEGUE) sub-survey of the SDSS. We confirm the existence of a bimodal CN distribution among RGB stars in all of the clusters with metallicity greater than [Fe/H] = -1.7; the lowest metallicity cluster with an observed CN bimodality is M53, with [Fe/H] ~ -2.1. There is also some evidence for individual CN groups on the subgiant branches of M92, M2, and M13, and on the red giant branches of M92 and NGC 5053. Finally, we quantify the correlation between overall cluster metallicity and the slope of the CN bandstrength-luminosity plot as a means of further demonstrating the level of CN-enrichment in cluster giants. Our results agree well with previous studies reported in the literature.

Examining the Pedagogical and Institutional Phenomena that Influence the Facilitation of Critical Consciousness
Creators: name: Pollard, Barb Anne
Publisher: name: Alberta Journal of Educational Research
Year: 2020

description: This study engaged grounded theory methodology to explore how critical pedagogy shaped and influenced the development of critical consciousness among preservice teacher candidates. The teacher participants revealed that facilitating critical consciousness was a complex process influenced by pedagogical and institutional mechanisms. The pedagogical mechanism of coercive power and the institutional mechanism of compressed time both limited opportunities for student agency and constrained the development of critical consciousness. Two professors were successful in countering the negative consequences of these institutional and pedagogical mechanisms by enacting a legitimate form of power and facilitating dialogical learning contexts. These efforts are highlighted in the paper as key attributes of consciousness raising learning experiences among the preservice teachers. Keywords: preservice teachers, critical pedagogy, critical consciousness, Faculty of Education, course-based learning experiences Cette étude, qui repose sur une méthodologie inspirée de la théorie à base empirique, explore la mesure dans laquelle la pédagogie critique a influencé le développement d’une conscience critique chez des enseignants en formation. Les enseignants participants ont révélé que la promotion de la conscience critique est un processus complexe qui est influencé par des mécanismes pédagogiques et institutionnels. Le mécanisme pédagogique du pouvoir coercitif et le mécanisme institutionnel du calendrier comprimé limitent tous les deux la marge de manœuvre des étudiants et contraignent le développement de la conscience critique. Deux professeurs ont réussi à contrer les conséquences négatives de ces mécanismes institutionnels et pédagogiques en exerçant une forme de pouvoir légitime et en facilitant des contextes d’apprentissage dialogique. L’article présente ces efforts comme étant les caractéristiques principales des expériences d’apprentissage ayant favorisé la prise de conscience chez les enseignants en formation.

Evaluation of  the Effects of Irrigation Water Pricing on  Water Productivity  in A  wash River Basin
Creators: name: Gebremeskel Teklay Berhe
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Irrigation  water  pricing  is  considered  to  be  one  of  the  tools  that  can  be  used  to  encourage
efficient  use  of water.  Awash  basin  is  the  only basin  that  operates with  the  concept  of river  basin
management  and  irrigation  water  pricing  in  Ethiopia.  The  effectiveness  and  impacts  of  the
current  irrigation water  pricing  system  in  the  basin has  not  been  studied  yet.  Hence,  the  objective
of  this  research  is  to  evaluate  effects  of  irrigation  water  pricing  on  scheme  level  water
productivity  in Awash River basin.
Based  on  systematic  selection  criteria  29  irrigation  water  users  were  selected  from  middle  and
upper Awash.  Structured  questionnaire  and  discussions  have  been  used  to  generate  the  primary
data.  Scheme  specific data  such  as  area  cultivated,  amount of water  diverted  each  year, water fee,
service  charge  and  operation  and  maintenance  cost  for  primary  irrigation  canals  of  each  legal
water  user  in  the  basin  for  the  last  five  consecutive  production  years  (2005/06-2009/10)  were
collected  from  Awash  Basin  Authority.  SPSS  and  CROPWAT  were  used  to  analyze  the
information  gathered  through  questionnaires  and  irrigation  water  requirement  respectively.
Water  productivity  of  cotton,  sugarcane  and  onion  was  computed  for  total  available  water
(excess  rainfall+  irrigation),  irrigation water and water  lost  through  crop  evapotranspiration. Five  years  average  irrigation water  productivity was  found  to  be  0.204,  l l .836  and  2.039 Kg/m3
for  Cotton,  sugarcane  and  onion  respectively.  The  current  irrigation  water  pricing  in  Awash
basin  seems  to  be  low  and  does  not  encourage  individual  users  in  improving water  productivity.
At  the  moment  cost  of  irrigation  water  does  not  influence  irrigation  water  demand,  area
expansion,  crop  selection  and  cropping  pattern.  Hence,  it  is  resulted  in  low  crop  water
productivity.  The  results  of  users'  willingness  to  pay  indicated  that  23  %  of  the  surveyed  users
are  willing to  pay  9Birr/l 000m3
of water  used whereas  only 4%  of the  respondents would  like  to
pay  l 2ETB/1000m3.
It  is  important  to  raise  the  awareness  of  the  users  about  the  importance  of
water  pricing  and  improving  the  service  of water  provision  by  the  authority.  Therefore,  cost  of
irrigation  water  in  Awash  basin  should  have  to  be  optimized  with  a well  specified  and  revised
pricing objective(s)  if  it  has  to  influence  the water  productivity.

description: Water  resources  are  basic  renewable  natural  resources  that  are  the  essential
requirements  for  the  existence  and  development  of  any  society.  Proper
utilization  of  these  resources  demands  assessment  and  management  of  the
quantity and quality of  the water  resources both spatially and temporally.
This study  focused mainly on  hydrological  characterization  and  application  of  a
GIS  based  semi-distributed watershed  model  (HEC-HMS)  to  establish  rainfall­
runoff  relationships  in  the  Gilgel Abbay Sub-basin, which  is  found  in  the  upper
most part of  the Abbay  (Blue Nile) River Basin,.
From  the  hydrological  characterization  it  could  be  observed  that  the  Gilgel
Abbay  sub-basin  has  got  a  high  annual  runoff  yield.  The  mean  annual
discharge at  the  outlet of  the  sub-basin  (gauging  station)  is  1044.2mm and  the
mean annual  rainfall  is 2030.9mm; hence the  runoff coefficient  is 0.513. The  semi  distributed  GIS  based  model,  HEC-HMS  was  applied  for  both  long
term  and  short  term  simulations. And  in  both  cases  four combinations of  basin
models were  used. According  to  R"2  and  IVF criteria,  the model  set containing
Initial  and  Constant method  of  excess  runoff  volume  determination,  Snyder
Unit Hydrograph  and  Recession method  of  base  flow  estimation was  found  to main  inputs  to  the  model  were  daily  rainfall  (mm),  potential  evaporation  (mm)
and  observed  daily flow  (m3
/s). The main output from  the model  is  daily stream
flow  (m3
/s). After  the model was  calibrated  and validated  the  impact  of  climatic
change on  the flow from  the catchment was analyzed.

description: In this paper we study the effects of the Generalized Uncertainty Principle (GUP) on the spectrum of a particle that is bouncing vertically and elastically on a smooth reflecting floor in the Earth's gravitational field (a quantum bouncer). We calculate energy levels and corresponding wave functions of this system in terms of the GUP parameter. We compare the outcomes of our study with the results obtained from elementary quantum mechanics. A potential application of the present study is discussed finally.

description: The main aim of the work is to present a general class of two time scales discrete-time epidemic models. In the proposed framework the disease dynamics is considered to act on a slower time scale than a second different process that could represent movements between spatial locations, changes of individual activities or behaviours, or others. To include a sufficiently general disease model, we first build up from first principles a discrete-time Susceptible-Exposed-Infectious-Recovered-Susceptible (SEIRS) model and characterize the eradication or endemicity of the disease with the help of its basic reproduction number R0. Then, we propose a general full model that includes sequentially the two processes at different time scales, and proceed to its analysis through a reduced model. The basic reproduction number R0 of the reduced system gives a good approximation of the R0 of the full model since it serves at analyzing its asymptotic behaviour. As an illustration of the proposed general framework, it is shown that there exist conditions under which a locally endemic disease, considering isolated patches in a metapopulation, can be eradicated globally by establishing the appropriate movements between patches.

description: In  Burundi,  agriculture  accounts  for  approximatively  80%  of  the  economically
active  population  and  it  remains  a  very  important  economic  sector.  In  this  part  of
the  world  rainfed  agriculture  is  largely  dominant;  food  security  and  income  of
rural  populations  are  vulnerable  to  rainfall  variability.  Therefore,  rainfall  being  an
important  climatic  element  in  crop  production  in  Burundi,  the  main  objective  of
this  research  was  to  analyze  the  spatial  and  temporal  variability  of  rainfall  in
Burundi.  For  this  purpose,  16 meteorological  stations  with  30  years  of  data  record
have  been  used.  Investigation  of  monthly,  seasonal  and  annual  rainfall  variability
using  different  methods  reveals  that  there  is  spatial  variability  of  rainfall  in
Burundi.  The  results  indicated  that  temporal  distribution  of  annual  rainfall  didn't
show  significant  change  within  the  period  considered.  The  seasonal  variability
analysis  shows  that  the  temporal  distribution  of  the  two  main  seasons  is  variable
from  year  to  year.  From  monthly  rainfall  variability  analysis,  the  months  of  May,
June,  July,  August,  September  and  October  are  characterized  by  high  variability in  rainfall  data  series  indicating  low  reliability  of  rainfall  during  these  periods.
The  remaining  months  of  the  year  showed  less  to  moderate  variability.  Another
observation  is  that  rainfall  variation  increases  as  the  time  becomes  shorter,  i.e.
the  variability  is  higher  when  evaluated  on  monthly  basis  than  on  annual  basis.
Trend  detection  analysis  conducted  using  Mann-Kendall  non-parametric  test  on
monthly  rainfall  series  with  high  variability  showed  negative  trend  indicating  the
decrease  in  precipitation,  but  this  trend  was  statistically  significant  for  some
months  and  stations.  Because  of  variability  of  rainfall  in  space  within  the  study

description: Mesoscopic non-equilibrium thermodynamics is used to formulate a model describing non-homogeneous and non-Debye dielectric relaxation. The model is presented in terms of a Fokker-Planck equation for the probability distribution of non-interacting polar molecules in contact with a heat bath and in the presence of an external time-dependent electric field. Memory effects are introduced in the Fokker-Planck description through integral relations containing memory kernels, which in turn are used to establish a connection with fractional Fokker-Planck descriptions. The model is developed in terms of the evolution equations for the first two moments of the distribution function. These equations are solved by following a perturbative method from which the expressions for the complex susceptibilities are obtained as a functions of the frequency and the wave number. Different memory kernels are considered and used to compare with experiments of dielectric relaxation in glassy systems. For the case of Cole-Cole relaxation, we infer the distribution of relaxation times and its relation with an effective distribution of dipolar moments that can be attributed to different segmental motions of the polymer chains in a melt.

description: We propose Shotgun, a parallel coordinate descent algorithm for minimizing L1-regularized losses. Though coordinate descent seems inherently sequential, we prove convergence bounds for Shotgun which predict linear speedups, up to a problem-dependent limit. We present a comprehensive empirical study of Shotgun for Lasso and sparse logistic regression. Our theoretical predictions on the potential for parallelism closely match behavior on real data. Shotgun outperforms other published solvers on a range of large problems, proving to be one of the most scalable algorithms for L1.
Evolutionary dynamics of ovarian cancer microenvironments and tumour cells

description: High-grade serous ovarian cancer (HGSC) is the most common and lethal histotype of epithelial ovarian cancer. Often presenting as multi-site disease, HGSC exhibits extensive malignant clonal diversity with widespread but non-random patterns of disease dissemination. The proclivity of HGSC toward clonally heterogeneous disease is thought to underlie the prevalence of treatment-resistant disease. Yet, the factors that influence the spatial distribution of cancer clones in HGSC remain largely uncharacterized. Hypothesizing that distinct peritoneal niches formed by microenvironmental cell types shape the observed patterns of clonal dynamics in HGSC, the primary aim of this thesis was to understand how microenvironmental factors influence malignant cell evolutionary dynamics. To establish the experimental substrate for this thesis, I led the construction of a cohort of 148 tumour samples from 41 HGSC cases (Chapter 2). In addition to coordinating clinical case identification, I oversaw and learned how to create patient-derived xenograft models and conduct single cell experiments from patient tumours. Leveraging this resource, I explored whether local immune microenvironment factors shape tumor progression properties at the interface of tumor-infiltrating lymphocytes and cancer cells (Chapter 3). Through multi-region study with whole-genome sequencing, immunohistochemistry, image analysis, gene expression profiling, and T- and B-cell receptor sequencing, I identified three immunologic subtypes across samples associated with patterns of malignant clonal diversity. These findings were consistent with immunological pruning of tumor clones. Finally, in order to explore the non-lymphocytic components of the tumour microenvironment, I developed an automated approach to cell type identification from single cell RNA-seq data that eliminates the manual work involved in traditional workflows reliant on post-hoc expert annotation (Chapter 4). I demonstrated how this method performs superiorly to state-of-the-art workflows for cell type identification and applied the method to profile the HGSC microenvironment. Collectively, this work highlights multiple interfaces of evolutionary interplay between malignant and non-malignant cells in the HGSC microenvironment, identifying novel mechanisms by which tumour cells escape from immune recognition. These results will inform the interpretation of results from immunotherapy clinical trials and set the stage for comprehensive microenvironment profiling in large HGSC cohorts and other cancers.

GIS- BASED SURFACE IRRIGATION POTENTIAL ASSESSMENT IN THE CASE STUDY OF TEMICHA WATERSHED EAST GOJAM ZONE OF AMHARA REGION
Creators: name: MAMENIE NIBRET
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Irrigation  is  an  important  investment  for  improving  rural  income  through  increased
agricultural production.  The  development of irrigation and agricultural water management
holds significant potential to enhance productivity and reduce vulnerability to the clim actic
volatility in any country.  The  major consequence of irrigation development are fluctuations
of basic climatic elements such as rainfall, temperature, humidity , and other atmospheric
conditions.  This study was concerned  with assessment of surface irrigation potential in the
Temicha watershed by implementing Arc GIS 10.1. The study identifies suitable land,  crop
water demand and supply for dominant crops grown in the catchment, and also providing
suitability  maps  for  surface  irrigation  development.  To  identify  suitable  land  the  land
suitability parameters were used such as land slope, soil type and land cove r land uses.
The  suitability  of  each  parameters  analyze  individually  and  then  application  of  the
weighted overlay tool was provided to get the overall suitability factors and suitability was
conducted by considering FAO criteria for surface irrigation deve lopment. The crop water
requirement of  major  growing crops of the study area were  identified based on some earlier
studies and agro climatic condition of the study area i.e. Wheat and Maize and its demand
of water was estimated  by implementing CROPWAT-8 model as an input of climatic data’s.
The stream flow data in the watershed were assessed by implementing the SWAT model
with an interface Arc GIS 10.1 software. The model  was calibrated and validated from
observed stream flow of the watershed. The calibration and validation result showed that
model performance evaluation statistics coefficient of determination (R
2
), Nash-Sutcliffe
model efficiency (ENS) and Relative Volume Error (RVE) were in the acceptable range (R
2
>  0.8, ENS  >  0.8 and RVE  <  -10 % ).  This shows  that a good agreement between the
simulated and observed values. The result of  the  weight overlay analysis revealed that
45.5% (49629.2 ha) of lands in the  watershed  were in  the range of highly sui table for
marginally suitable class due to the combined effect of slope, soil and land use land cover
suitability and 54.5% (59445.9 ha) of the area were unsuitable for surface irrigation. So
that,  the  current  study  considered  only  slope,  land  use  land  cov er  and  soil  physical
properties  but  other  suitability  factors  like,  socioeconomic,  environmental  issues,  soil
chemical properties, method of irrigation system and other relevant parameters should be
studied for detail assessment of irrigation development in the study area

description: Estimation  of  Potential  evapotranspiration  is  important  in Water  Resources
development  program.  However,  there  is  no  standardized  procedure  in
ungauged stations of the country.
In  order  to  address  this  problem,  Regionalization  through  Multivariate
regression  models  of  average  monthly  potential  evapotranspiration  is
developed  for  the  Blue  Nile  (Abbay)  River basin. Average monthly  values  of
daily  PET,  is  estimated  from  the  Penman-Monteith  equation  using  13 years
(1992-2004)  monthly  climate  data  collected  from  25  synoptic  stations  of  the
National  Meteorological  services Agency.  The  periodic  seasonal  behavior of
E,  (r)  and  average monthly temperatures  are  approximated  by  Fourier series
functions  with  two  harmonics.  Regional  regression  relationships  are  then
developed which  relate  the  E, (r)  Fourier series coefficients with  the  average
monthly  temperature  Fourier  coefficients,  station  latitude,  station  longitude
and station elevation. The regional model developed,  £1

it  is  shown  to  be  an  improvement over  the  Priestly-Taylor method  (Priestley,

method  (Hargraves  and  Samani,  1985),  and  the  regional  model  also  shown
to  be  an  improvement over ·other previously developed model  (equations)  for
the basin  in particular (Sileshi, 2002).
