Socioecological analysis of smallholder farming systems in the Philippines : identifying multi-scalar pathways and barriers to resilience
Creators: name: Heckelman, Amber
Publisher: name: University of British Columbia
Year: 2019

description: Climate change poses serious threats to agriculture. The Philippines is one of the foremost countries impacted by climate change, with extensive coastlines, high population density and heavy dependence on agriculture. Many smallholders are struggling to cope with intensified typhoons, changing rain patterns, floods, droughts, as well as temperature and sea-level rise. As a primary staple crop embedded in the socioecological fabric of the Philippines, rice systems are of particular significance to resilience building efforts. This dissertation engages in a socioecological analysis of smallholder farming systems within the Philippine rice sector, with the broader aim to identify multi-scalar pathways and barriers to building climate resilience. Drawing on fieldwork conducted between August-December 2016, this dissertation shares the results of a comparative assessment of organic and conventional rice systems located in Negros Occidental Province, an institutional analysis of the organic transition currently underway in the Philippines, and an exploration of a grassroots farmer-led network and their polycentric food sovereignty development approach. Primary data was collected via surveys, key informant interviews, focus group discussions, farmer interviews, and participant observation. My findings suggest that participating organic rice systems are more climate resilient than their conventional counterparts. Despite increased institutional support for organic agriculture, institutional arrangements remain largely oriented toward promoting Green Revolution technologies; obstructing the speed and scale of organic transition and limiting smallholder capacities for building resilience. To overcome adverse socioecological conditions, smallholders have organized into a polycentric network to implement food sovereignty initiatives that increase farmer control over agricultural resources. This bottom-up and multi-scalar development approach has helped smallholders across the Philippines transition to diversified organic systems, as well as enhanced local capacities for resilience building. The evidence presented here suggests that enhancing smallholder resilience in the Philippines requires improving the socioecological conditions for farmers to engage in adaptation and mitigation strategies, as well as community development efforts to reduce their vulnerabilities. To this end, agricultural policy, development agencies, and researchers must work towards capacity building alongside farmers to regenerate agrobiodiversity and locally available resources, facilitate social learning and collective action, as well as address the root causes of their political economic marginalization.
Educating Preservice Teachers in a Neoliberal Era: Specialized Technicians or Public Intellectuals?

description: Neoliberalism’s influence on teacher education has intensified a view of teachers as skilled technicians trained to implement centrally developed curriculum rather than as public intellectuals who engage in self-reflection and critique. In this paper, reforms in the United States and England provide a context for discussing teacher education programs in Canada. Young and Boyd’s (2010) “modes of governance” and “images of teachers work” provide a way to conceptualize teachers as public intellectuals that may be useful to counter neoliberal conceptions. Since neoliberal reforms continue to influence both universities and K-12 education, teacher educators are uniquely challenged to maintain a critical perspective on the role of teacher education and teacher work. L’influence du néolibéralisme sur la formation des enseignants a intensifié une perspective selon laquelle les enseignants sont des techniciens spécialisés et formés pour mettre en œuvre un programme d’études élaboré par des autorités centrales plutôt que des intellectuels publics qui pratiquent l’autoréflexion et l’autocritique. Cet article emploie des réformes aux États-Unis et en Angleterre comme cadre pour une discussion sur les programmes de formation des enseignants au Canada. Les « modes de gouvernance » et les « perceptions du travail des enseignants » de Young et Boyd (2010) offrent une façon de conceptualiser les enseignants comme des intellectuels publics. Ce moyen pourrait s’avérer utile pour contrer les perceptions néolibérales. Puisque l’influence des réformes néolibérales continue à se faire sentir dans le milieu universitaire et dans celui de l’éducation K-12, les formateurs d’enseignants sont confrontés au défi particulier de maintenir une perspective critique sur le rôle de la formation et du travail des enseignants.

description: Intelligent mobile sensors, such as uninhabited aerial or underwater vehicles, are becoming prevalent in environmental sensing and monitoring applications. These active sensing platforms operate in unsteady fluid flows, including windy urban environments, hurricanes and ocean currents. Often constrained in their actuation capabilities, the dynamics of these mobile sensors depend strongly on the background flow, making their deployment and control particularly challenging. Therefore, efficient trajectory planning with partial knowledge about the background flow is essential for teams of mobile sensors to adaptively sense and monitor their environments. In this work, we investigate the use of finite-horizon model predictive control (MPC) for the energy-efficient trajectory planning of an active mobile sensor in an unsteady fluid flow field. We uncover connections between trajectories optimized over a finite-time horizon and finite-time Lyapunov exponents of the background flow, confirming that energy-efficient trajectories exploit invariant coherent structures in the flow. We demonstrate our findings on the unsteady double gyre vector field, which is a canonical model for chaotic mixing in the ocean. We present an exhaustive search through critical MPC parameters including the prediction horizon, maximum sensor actuation, and relative penalty on the accumulated state error and actuation effort. We find that even relatively short prediction horizons can often yield energy-efficient trajectories. We also explore these connections on a three-dimensional flow and ocean flow data from the Gulf of Mexico. These results are promising for the adaptive planning of energy-efficient trajectories for swarms of mobile sensors in distributed sensing and monitoring.

description: Recent studies suggest that high-energy neutrinos can be produced in the jets of blazars, radio-loud active galactic nuclei (AGN) with jets pointing close to the line of sight. Due to the relatively poor angular resolution of current neutrino detectors, several sources can be regarded as the possible counterpart of a given neutrino event. Therefore, follow-up observations of counterpart candidates in the electromagnetic regime are essential. Since the Very Long Baseline Interferometry (VLBI) technique provides the highest angular resolution to study the radio jets of blazars, a growing number of investigations are being conducted to connect individual blazars to given high-energy neutrino events. We analyzed more than 20 years of available archival VLBI data of the blazar CTD 74, which has been listed as a possible counterpart of a neutrino event. Using cm-wavelength data, we investigated the jet structure, determined the apparent speed of jet components, and the core flux density before and after the neutrino event. Our results indicate stationary jet features and a significant brightening of the core after the neutrino event.

description: Ultrachirped pulses for which the frequency chirp is of the order of the transition frequency of a two-level atom are examined. When the chirp is large enough, the resonance may be crossed twice, for positive and negative quadrature frequencies. In this scenario the analytic signal and quadrature decompositions of the field into amplitude and phase factors turn out to be quite different. The corresponding interaction pictures are strictly equivalent, but only as long as approximations are not applied. The domain of validity of the formal rotating wave approximation is dramatically enhanced using the analytic signal representation.
Multiband Nonthermal Radiative Properties of HESS J1813-178

description: The source HESS J1813-178 was detected in the survey of the inner Galaxy in TeV gamma-rays, and a SNR G12.8-0.0 was identified in the radio band to be associated with it. The PWN embedded in the SNR is powered by an energetic pulsar PSR J1813-1749, which was recently discovered. Whether the TeV gamma-rays originate from the SNR shell or the PWN is uncertain now. We investigate theoretically the multiwavelength nonthermal radiation from the composite SNR G12.8-0.0. The emission from the particles accelerated in the SNR shell is calculated based on a semianalytical method to the nonlinear diffusive shock acceleration mechanism. In the model, the magnetic field is self-generated via resonant streaming instability, and the dynamical reaction of the field on the shock is taken into account. Based on a model which couples the dynamical and radiative evolution of a PWN in a non-radiative SNR, the dynamics and the multi-band emission of the PWN are investigated. The particles are injected with a spectrum of a relativistic Maxwellian plus a power law high-energy tail with an index of -2.5. Our results indicate that the radio emission from the shell can be well reproduced as synchrotron radiation of the electrons accelerated by the SNR shock; with an ISM number density of 1.4 cm^{-3} for the remnant, the gamma-ray emission from the SNR shell is insignificant, and the observed X-rays and VHE gamma-rays from the source are consistent with the emission produced by electrons/positrons injected in the PWN via synchrotron radiation and IC scattering, respectively; the resulting gamma-ray flux for the shell is comparable to the detected one only with a relatively larger density of about 2.8 cm^{-3}. The VHE gamma-rays of HESS J1813-178 can be naturally explained to mainly originate from the nebula although the contribution of the SNR shell becomes significant with a denser ambient medium.

Shifted q = 0 affine algebras

description: In this thesis, we accomplish the following three things. 1. Defining the shifted q = 0 affine algebras (Chapter 2). 2. Explaining what it means for such algebra to act on categories (Chapter 3). 3. Giving an example of such a categorical action (Chapter 5). Our motivation comes from the categorification of quantum groups and their action on categories. On the derived categories of coherent sheaves on Grassmannians or partial flag varieties, we try to understand an action via using the language of Fourier-Mukai transformations with kernels inducing by natural correspondences. After decategorifying, the q = 0 shifted affine algebras are similar to the shifted quantum affine algebras defined by Finkelberg-Tsymbaliuk [FT], where some of the relations can be obtained from their relations by taking v = 0 (i.e. the q-analogue). Finally, we relate shifted q = 0 affine algebras to q = 0 affine Hecke algebras. In particular, we use the action of shifted q = 0 affine algebras to construct an action of the q = 0 affine Hecke algebras on the derived category of coherent sheaves on full flag varieties. We also relate this action to the notion of Demazure descent which was introduced in [AK1].

description: The  gravity  supply  of water  to  irrigation  fields  can  be  achieved  by  impounding
schemes  or diversion  schemes.  Unlike  impounding  dams,  diversion  structures
for  irrigation  are  usually exposed  to  the overflow action of water and  sediments.
Hence,  they are  liable to  exhibit problems &  predicting  their performance  under
this condition  is very difficult.
Accordingly,  irrigation  structures  demand  the  multi-faceted  considerations  of
hydrologic,  structural,  sediment  and  hydraulic  analysis,  geotechnical  &
agronomic  considerations  and  if  not  properly  designed,  .often  end  up  in
consequential  problems.  Thus,  practicing  engineer  in  the  field  often  faces  to
make  sure  this  problem  will  not  happen  in  the  designs  even  if  there  is  very
limited or no actual data  in the field.
A case study considering 26 existing small scale  irrigation works  (1/3 of the total
schemes)  in the south  region  is carried  out for this  research work and  attempt  is
made  to  understand  the  causes  of  the  major  problems  that  are  related  to  the
design  consideration  of  the  different  components  of  the  structure  and  identify
the gap  in  knowledge  between  the current design  practices  and  performance of the  structures.  The  pre  and  post  construction  institutional  aspects  and  water
management  problems  are  also  given  due  attention.  Some  of  the  many
structural  problems  in  the  existing  irrigation  structures  are  problems  of
sedimentation  at  the  headwork  and  main  canal,  downstream  scouring,
upstream  flooding,  damage  on  impervious  and  flexible  apron,  change  of  river

were overlay to each other in GIS so as to obtain the overall soil suitability and slope was
get hold of  from DEM of 30*30 pixel resolution through reclassifying according to FAO
guidelines.  LULC  of  the  study  area  was  also  done  after  importing  the  freely  available
satellite image of the area  and classified in supervised classification type using  the aid of
ERDAS  IMAGINE2014.  The  overall  suitability  was  done  through  weighted  overlay
analysis  of  the  slope,  soil  and  LULC  without  including  other  factors  of  irrigation
development.  Accordingly,  the  overall  soil  suitability  was  46.91%  ranging  from  highly
suitable to marginally suitable for the development of surface irrigation and about 4.06%
to  48.33%  slope  of  the  watershed  was  highly  suitable  to  marginally  suitable.  About
10.45%  of  LULC  was  non-suitable  for  the  development  of  surface  irrigation.  Grossly
28.11%,   of  the  catchment  area  could  potentially  be  developed  in  Beresa  with  the
available  flow  of  the   river.  Other  irrigation  suitability  factors  such  as  soil  chemical
properties,  socio-economic  aspects,  environmental  hazards  and  ground  water
investigation should be studied additionally in detail for further irrigation development as
well as enhancing sustainability over the study area.

description: The first dilemma that millions of poor in urban areas of the developing world face and

which is likely to persist for a long period was the question of adequate housing. In this

regard, 70 percent of the urban population of Ethiopia is living in slums and squatter

settlements. This research study was focus on the trend of squatter settlements in Burayu

city in Oromiya National Regional State, Ethiopia. The research tries to identify the

practices of squatting and assess the local government responses in Burayu city. By the

combination of random and purposive sampling method, 300 squatter households were

selected from different parts of the city and quantitative data and qualitative information

were collected from primary as well as secondary sources to analyze. The result shows that

squatter settlements growth rate is alarming and long run practice in its nature with an

average growth rate of 18.6% per year in the past five years. Currently there is also a

residential area development without legal claims to the land and/or permission from the

concerned authorities to build; the overwhelming proportion 85% of respondents claimed

that construction of illegal houses has continued. The main actors behind such illegal

settlement were networked government bureaucrats and brokers, and the root cause for

development and expansion of squatter settlements in Burayu city is not only economic

scarceness of the squatter households; awkward procedures and very poor performance of

LDMA to deliver the land to the aspirants was also a reason to the expansion

description: By offering effective modal volumes significantly less than a cubic wavelength, slot-waveguide cavities offer a new in-road into strong atom-photon coupling in the visible regime. Here we explore two-dimensional arrays of coupled slot cavities which underpin designs for novel quantum emulators and polaritonic quantum phase transition devices. Specifically, we investigate the lateral coupling characteristics of diamond-air and GaP-air slot waveguides using numerically-assisted coupled-mode theory, and the longitudinal coupling properties via distributed Bragg reflectors using mode-propagation simulations. We find that slot-waveguide cavities in the Fabry-Perot arrangement can be coupled and effectively treated with a tight-binding description, and are a suitable platform for realizing Jaynes-Cummings-Hubbard physics.

description: Understanding the travel challenges faced by low-income residents has always been and continues to be one of the most important transportation equity topics. This study aims to explore the mobility gaps between low-income households (HHs) and not low-income HHs, and how the gaps vary within different socio-demographic population groups in New York State (NYS). The latest National Household Travel Survey data was used as the primary data source for the analysis. The study first employed the K-prototype clustering algorithm to categorize the HHs in NYS based on their socio-demographic attributes. Five population groups were identified based on nine different household (HH) features such as HH size, vehicle ownership, and elderly status of its members. Then, the mobility differences, measured by trip frequency, trip distance, travel time, and person miles traveled, were examined among the five population groups. Results suggest that the individuals in low-income HHs consistently took fewer trips and made shorter trips compared to their not low-income counterparts in NYS. The travel distance gaps were most obvious among white HHs with more vehicles than drivers. In addition, while the population from low-income HHs made shorter trips on average (2.7 mi shorter per trip), they experienced longer travel time than those from not low-income HHs (1.8 min longer per trip). These key findings provide a deeper understanding of the travel behavior disparities between low-income and not low-income households. The findings could also support policymakers and transportation planners in addressing the critical needs of residents in low-income households in NYS and provide inputs for designing a more equitable transportation system.

description: We characterize models where electroweak symmetry breaking is driven by two light Higgs doublets arising as pseudo-Nambu-Goldstone bosons of new dynamics above the weak scale. They represent the simplest natural two Higgs doublet alternative to supersymmetry. We construct their low-energy effective Lagrangian making only few specific assumptions about the strong sector. These concern their global symmetries, their patterns of spontaneous breaking and the sources of explicit breaking. In particular we assume that all the explicit breaking is associated with the couplings of the strong sector to the Standard Model fields, that is gauge and (proto)-Yukawa interactions. Under those assumptions the scalar potential is determined at lowest order by very few free parameters associated to the top sector. Another crucial property of our scenarios is the presence of a discrete symmetry, in addition to custodial SO(4), that controls the $T$-parameter. That can either be simple CP or a $Z_2$ that distinguishes the two Higgs doublets. Among various possibilities we study in detail models based on SO(6)/SO(4)$\times$ SO(2), focussing on their predictions for the structure of the scalar spectrum and the deviations of their couplings from those of a generic renormalizable two Higgs doublet model.

description: Truck transportation remains the dominant mode of US freight transportation because of its advantages, such as the flexibility of accessing pickup and drop-off points and faster delivery. Because of the massive freight volume transported by trucks, understanding the effects of population and employment characteristics on truck flows is critical for better transportation planning and investment decisions. The US Federal Highway Administration published a truck travel origin-destination data set as part of the Next Generation National Household Travel Survey program. This data set contains the total number of truck trips in 2020 within and between 583 predefined zones encompassing metropolitan and nonmetropolitan statistical areas within each state and Washington, DC. In this study, origin-destination-level truck trip flow data was augmented to include zone-level population and employment characteristics from the US Census Bureau. Census population and County Business Patterns data were included. The final data set was used to train a machine learning algorithm-based model, Extreme Gradient Boosting (XGBoost), where the target variable is the number of total truck trips. Shapley Additive ExPlanation (SHAP) was adopted to explain the model results. Results showed that the distance between the zones was the most important variable and had a nonlinear relationship with truck flows.

description: We propose that the logarithmic term in the entanglement entropy computed in a conformal field theory for a $(d-2)$-dimensional round sphere in Minkowski spacetime is identical to the logarithmic term in the entanglement entropy of extreme black hole. The near-horizon geometry of the latter is $H_2\times S_{d-2}$. For a scalar field this proposal is checked by direct calculation. We comment on relation of this and earlier calculations to the ``brick wall'' model of 't Hooft. The case of generic 4d conformal field theory is discussed.

description: Urban schools in high-poverty communities face unique challenges. It is often the school principal who is tasked with addressing achievement gaps, low scores and students with high needs. Despite the importance and the difficulties of their role, the voices of many of these dedicated leaders are not often heard. This narrative inquiry shares the insights of two elementary principals in urban schools who recount the barriers, supports and rewards of their role. Using moral leadership as a theoretical framework, the findings of this study include a call for school boards to consider carefully the qualities and passions of their leaders when assigning principals to urban schools. Keywords: principal, moral leadership, high-poverty, urban schools, narrative inquiry Les écoles en milieux urbains avec des taux élevés de pauvreté font face à des défis uniques. Il revient souvent aux directeurs d’école de répondre aux écarts en matière de rendement, aux faibles résultats et aux élèves ayant des besoins élevés. Malgré l’importance et les difficultés de leur rôle, les voix de plusieurs de ces leaders dévoués ne se font pas souvent entendre. Cette enquête narrative présente les perspectives de deux directeurs d’écoles primaires urbaines qui racontent les obstacles, les supports et les récompenses qui les accompagnent dans leur rôle. Reposant sur le leadership moral comme cadre théorique, les résultats évoquent, entre autres, le besoin pour les conseils scolaires d’examiner soigneusement les qualités et les passions de leurs leaders lors de l’affectation des directeurs dans les écoles urbaines.

The importance of cofilin and Rap GTPases in Fcε Receptor I-mediated actin-dependent mast cell effector functions
Creators: name: Pritchard, Caitlin Jean
Publisher: name: University of British Columbia
Year: 2019

description: Mast cells are central players in inflammatory responses, as they secrete a number of factors that regulate the responses of other immune cells and they participate in pathogen sensing and clearance. However, mast cells are best known for their role in allergic diseases. Mast cells express the cell surface receptor, Fcε Receptor I (FcεRI), which binds the constant region of IgE antibodies. Binding of multivalent antigens to FcεRI-bound IgE initiates intracellular signaling cascades that lead to effector functions such as degranulation and migration. During degranulation, storage granules containing pre-synthesized bioactive molecules such as histamine fuse with the plasma membrane and release their contents. Secretion of granule contents requires dynamic reorganization of the submembrane actin cytoskeleton. Actin dynamics are also required to generate protrusive forces at the leading edge of the cell during antigen-induced mast cell migration. Despite the importance of the actin cytoskeleton for mast cell-mediated immune responses, how actin dynamics are regulated during mast cell activation is poorly understood. Although the actin severing protein, cofilin, is activated by FcεRI signaling, the role of cofilin in actin-dependent mast cell functions has not been investigated. By using siRNA to deplete cofilin in a murine bone marrow-derived mast cell line, I found that cofilin is important for FcεRI-induced actin breakdown as well as mast cell degranulation, cell spreading, and migration. Potential upstream regulators of cofilin activity and actin remodeling are the Rap GTPases but their role in mast cells has not been investigated. The Rap GTPases are members of the Ras family of GTPases that are important for actin reorganization, integrin activation, cell polarity, and proliferation. I showed for the first time that the Rap1 and Rap2 GTPases are activated by FcεRI signaling. Furthermore, I found that Rap1 and Rap2 were important for FcεRI-induced actin breakdown and migration towards antigen but not for degranulation or cell spreading. Interestingly, Rap1 and Rap2 acted independently of cofilin to regulate actin turnover. This work has identified two novel regulatory pathways that facilitate actin-dependent FcεRI-induced mast cell effector functions and broadens our understanding of the signaling pathways that regulate mast cell activation in allergy and inflammation.

description: We investigate the morphologies and maximum packing density of thin wires packed into spherical cavities. Using simulations and experiments, we find that ordered as well as disordered structures emerge, depending on the amount of internal torsion. We find that the highest packing densities are achieved in low torsion packings for large systems, but in high torsion packings for small systems. An analysis of both situations is given in terms of energetics and comparison is made to analytical models of DNA packing in viral capsids.

EVALUATION OF WATER DELIVERY PERFORMANCE IN ROBIT SMALL SCALE IRRIGATION SCHEME, AMHARA, ETHIOPIA
Creators: name: ABRHA YBEYN GEBREMEDHN
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Robit small-scale irrigation scheme is located in the Amhara National Regional State and
was constructed in 2012. However, the performance of the irrigation scheme has not been
evaluated yet. In the present study, the performance of the scheme was evaluated by
estimating water delivery performance indicators, water conveyance efficiency, water
conveyance losses, and satisfaction of irrigation users. The water delivery performance
adequacy, efficiency, equity and dependability were evaluated by monitoring discharge at
nine selected offtakes; three each at the head, middle and tail end of the scheme command
area during the crop season from April to June 2017. The water conveyance efficiency of
the main and secondary canals and thus the water losses in water conveyance were
estimated by measuring irrigation water flow at different locations along the canals. The
satisfaction of the irrigation water users from the irrigation service received was
evaluated using the binary Logit Model at the head, middle and tail end of the irrigation
scheme, and for the entire irrigation scheme. Irrigation water flow in the main and
secondary canals, as well as at nine tertiary offtakes was measured using Current meter
and 3-inch Parshall flume. The data were analyzed using STATA, CROPWAT, ARC GIS
software, and Microsoft Excel. The water delivery performance indicators adequacy,
efficiency, equity and dependability varied widely from head to tail reach and, during the
crop season from April to June with overall average value equal to 0.88, 0.92, 0.09 and
0.11 respectively. Thus, the irrigation scheme when compared with Molden and Gates
(1990) standards was found under fair condition in adequacy and dependability and
under good condition in efficiency and equity. The estimated overall water conveyance
efficiencies of the main canal and first and second secondary canals were 90.3%, 82.88%
and 82.83% respectively. Similarly, the water conveyance losses per 100 m were 2.62,
1.56 and 1.18 ls
-1
 for the main canal and first and second secondary canals respectively.
The level of irrigation users' satisfaction from the irrigation service received was 57.33%,
48%, 42.67% and 49.33% at the head, middle, tail reach and the entire system
respectively. Satisfaction of irrigation users was found highly associated with the
variation in the availability of adequate water, water availability in time and farm
location from the canal head.
“I Needed to Rediscover who I Really Was”: An Inquiry into the Impacts of one Graduate Teacher Education Program for Early Elementary Teachers

Publisher: name: Alberta Journal of Educational Research
Year: 2018

description: This paper reports on the impacts on teachers of a new Masters in Education program developed for early elementary teachers at one small Canadian university. Central to the program are concepts of the child as competent and capable, and a view of professional learning as democratic, critically reflective and a way to enhance teacher agency. Our findings are based on interviews and focus group conversations with several members of one of the cohorts who completed the program. In our thematic analysis we determined that teachers reported changes in their practices including slowing down and listening to children as well as increased flexibility and ability to relinquish control. Additionally, teachers spoke of increased confidence in themselves and the children in their classrooms as a result of participating in this program. Keywords: early elementary grades, graduate teacher education, early elementary pedagogy, democratic professional learning, teachers’ agency Cet article fait état des impacts sur les enseignants d’un nouveau programme de maitrise en éducation développé par une petite université canadienne pour les enseignants du primaire. Le programme est centré sur le concept selon lequel l’enfant est compétent et capable, et sur une perspective de l’apprentissage professionnel comme étant un processus de réflexion critique qui est démocratique et susceptible d’augmenter chez les enseignants le sentiment de pouvoir agir. Nos résultats découlent d’entrevues et de conversations avec des groupes de discussion impliquant plusieurs membres d’une cohorte ayant complété le programme. Notre analyse thématique révèle que les enseignants ont signalé des changements dans leurs pratiques; entre autres, ils ont indiqué qu’ils ralentissaient et écoutaient les élèves, étaient plus souples et se sentaient en mesure de céder le contrôle. De plus, les enseignants ont reconnu que leur participation au programme avait entrainé une augmentation de leur confiance en soi et en les élèves. Mots clés : premières années du primaire, études supérieures en enseignement, pédagogie des premières années du primaire, sentiment chez les enseignants de pouvoir agir.
