Peer tutoring as an instructional strategy has been used by school personnel to increase academic achievement in the classroom setting. Traditionally, the peer tutoring concept relies on student partnerships linking higher achieving students with lower achieving students for structured reading sessions. Recently, new studies have focused on linking students with comparable reading achievements or cross-age peer tutors. Research suggests that using peer tutors may promote higher reading fluency in at-risk students as compared to teacher instruction. A potential reason for this phenomenon includes students’ comfort level with peers allowing for a more easy development of reading growth. The purpose of this study is to determine the effectiveness, efficiency, and scalability of cross-age peer tutoring on reading fluency and reading comprehension. The study involved 7 fifth grade struggling readers as tutors to 7 third grade struggling readers. Reading to Read was used as the intervention protocol. The dyads met for 5 weeks with progress monitoring conducted at the beginning of each week. Results indicated consistent benefit in improving reading fluency in 13 of the 14 participants. Several implications to the study can be identified. Peer assisted learning can benefit both participants in reading fluency. Participating in the peer assisted learning process improves the attitudes toward reading of below grade level readers. Further implications, limitations, and future research relating to the results of this study are also discussed.

Referendums are enigmatic in their sense as consolidating— or erosive tools of representative democracy; nonetheless, an upswing in the referenda from below was recently highlighted in the literature. Thus, how local referendums from below are mobilized and whether they affect trust in local government is a significant question to be answered, which mandates bridging social movements to tools of deliberative democracy. Similarly, little is known about urban social movements and local patriotism as tenon and its mortise in a sub-national referendum. Therefore, this paper set sail from the role of local patriotism within collective action and aimed at exploring how locals are mobilized to petition a local referendum regarding the liquidation of a cityscape. Within an exploratory holistic single-case study design, I used QCA to analyse the data gathered through semi-structured interviews with members of The People’s Initiative for the Airport Future and various peculiar secondary data. The evidence was compelling in depicting the respondents’ solid spatial belonging— and an unmistakable altruistic stance towards Västerås manifested through political participation. Along with other conclusions, the evidence advocated a persuasive presence of local patriotism, a tendency to resort to unconventional political participation, and a fragmented trust in local government among the respondents.

Wetlands serve important ecosystem functions such as carbon sequestration but are often affected by disturbances like urban development, agriculture, and road building. For wetlands created to mitigate losses, it is important that the ecosystem functions successfully replicate those of natural wetlands. Created wetlands have frequently not provided these functions due to issues including low organic carbon (OC), high soil bulk density (BD), lost topsoil, incorrect hydrology, and failure of targeted vegetation establishment. Organic matter (OM) amendments help created wetlands attain these functions quicker, but, their long-term effects are seldom reported. This research's purpose was to measure the long-term effects of treatments at a sandy tidal freshwater wetland created in 2003 (WWE) and a fine-textured, non-tidal wetland created in 2002 (CCW). We tested OM treatments, topsoil amendment, and microtopography effects on soil and vegetation properties at WWE and OM treatments at CCW. Pedogenic changes in soil morphology, physical and chemical properties were detected by comparing data to previous studies at these sites. At both sites, litter and biomass parameters were measured to estimate total mass C. Herbaceous biomass was measured at WWE. At WWE, no long-term OM treatment effects from 78 or 156 Mg ha-1 were observed. Soils in pits had higher OC, lower BD, and lower chroma than soils on mounds. Sandy and loamy HSFI's developed at WWE within four years, but there were fewer sandy indicators after 12 years. Loamy HSFI's were lost at CCW from 2003 to 2016. Plots at WWE that were amended with topsoil had higher soil mass C than the sandy soil due to a finer texture, but total mass C did not vary. At CCW, long-term OM treatment effects were observed, including lower BD, higher soil mass C, and higher tree mass C with increasing compost rates up to 224 Mg ha-1. Overall, the ideal compost loading rate for constructed wetlands varied with wetland type and mitigation goals. Compost rates of 112 Mg ha-1 are sufficient for short term establishment of wetland vegetation and hydric soil properties, but higher rates near 224 Mg ha-1 may be required for effects that last over 10 years. / Ph. D. / Wetlands are unique habitats that provide environmental benefits such as carbon storage but are often negatively affected by human disturbances such as urban development and road construction. When wetlands are constructed to mitigate natural wetland losses, it is important that they successfully provide the benefits of the wetlands they replace. Created wetlands have frequently not functioned like natural wetlands due to soil issues including low organic carbon (OC) and high soil density (BD). Organic matter (OM) amendments such as composted yard waste help created wetlands attain these functions quickly after construction compared to unamnded wetlands. The purpose of this study was to measure long-term (greater than 10 years) effects of OM treatments on soil and vegetation properties at two different created wetlands. The two wetlands were a sandy tidal freshwater wetland created in 2003 (WWE) and a fine-textured, compacted, non-tidal wetland created in 2002 (CCW). Previous soil data were compared to recent soil samples to detect changes in physical and chemical soil properties over time. At WWE, soils in pits accumulated more OM, were higher in carbon, lower in BD, and had greyer color than soils in mounds. Hydric soil field indicators developed from upland soil within four years after construction at WWE. There were no long term compost effects on soil properties compared to a fertilized control, but the compost rates used were low compared to other recommendations, and the wetland was constructed carefully to avoid compaction. There were much higher rates of compost applied at CCW, which produced lower BD, higher soil mass C, and higher tree biomass. We recommend applying OM and avoiding compaction during wetland construction. Ideal OM loading rate depends on wetland type (soil texture, hydrology) and mitigation goals. In the fine-textured, compacted wetland studied here, compost rates of 112 Mg ha⁻¹ are ideal for short term establishment of wetland vegetation and soil properties, but higher rates near 224 Mg ha⁻¹ may be required for long term effects.

Cette thèse a pour objectif d’étudier les représentations et les récits liés aux aménagements controversés que peuvent être les barrages hydrauliques. Si la fonction symbolique des barrages a souvent été soulignée par la littérature scientifique, peu de travaux sont réellement consacrés à leurs représentations et à leurs trajectoires spatiales et temporelles. En s’inspirant d'études issues de la géographie sociale et culturelle sur les représentations et de la political ecology sur les discours, la thèse confronte différentes sources (presse, entretiens et archives), terrains (France et Australie) et approches méthodologiques (quantitatives et qualitatives) pour retracer l’évolution discursive des infrastructures hydrauliques. Les points de vue de différents acteurs sont aussi considérés: les habitants, les ingénieurs et les institutions hydrauliques, les opposants aux barrages, les administrations en charge de la protection de la nature ou encore les scientifiques qui produisent des connaissances sur l’environnement. D'un point de vue méthodologique, la thèse révèle les biais de certains matériaux et souligne l'intérêt de poursuivre leur croisement. Les résultats montrent l’évolution de waterscapes, d’espaces et de cycles hydrosociaux, par exemple les concessions progressives faites aux environnementalistes aux dépens des hydrocraties ; ils mettent aussi en avant, plus généralement, la production et la circulation de discours, notamment à l’occasion de conflits et de controverses, qui conduisent au délitement du discours prométhéen sur la nature et à la diffusion de représentations concurrentes de l'environnement. / The aim of this PhD thesis is to study representations and narratives on dams, which are often controversial infrastructures. If the symbolic role of dams has been underlined in the literature, few studies actually focus on the perception of dams and their spatial and temporal trajectories. Building on the literature of social and cultural geography on representation, and the writings of political ecology on discourse, this thesis confronts different sources (newspapers, interviews and archives), study areas (in France and Australia) and methodological approaches (quantitative and qualitative) in order to follow the discursive evolution of hydraulic infrastructure. The points of view of various stakeholders are also considered: inhabitants, engineers and hydraulic institutions, opponents to dams, administrations in charge of nature protection and scientists who produce environmental knowledge. From a methodologicial perspective, the dissertation highlights the limits of certain material and illustrates the necessity to consider different sources in parallel. The results show the evolution of waterscapes, hydrosocial spaces and cycles---the gradual concessions made to environmentalists at the expense of hydraulic bureaucracies---but they also illustrate, on a broader perspective, the production and the flow of discourses on the environment---the disaggregation of a Promethean discourse on nature and the multiplication of different and sometimes opposing representations of the environment---particularly during conflicts and controversies.

This research investigates soil respiration (Rs) in a boreal jack pine (Pinus banksiana Lamb.) fire scar chronosequence at Sharpsand Creek, Ontario, Canada. During two field campaigns in 2006 and 2007, Rs was measured in a chronosequence of fire scars in the range 0 to 59 years since fire. Mean Rs adjusted for soil temperature (Ts) and soil moisture (Ms) (Rs T,M) ranged from 0.56 μmol CO2/m2/s (32 years post fire) to 8.18 μmol CO2/m2/s (58 years post fire). Coefficient of variation (CV) of Rs adjusted for Ts and Ms ranged from 20% (16 years post fire) to 56% (58 years post fire). Across the field site, there was a significant exponential relationship between Rs adjusted for soil organic carbon (Cs) and Ts (P = 1.24*10-06; Q10 = 2.21) but no effect of Ms on Rs adjusted for Cs and Ts for the range 0.21 to 0.77 volumetric Ms (P = 0.702). Rs T,M significantly (P = 0.030) decreased after burning mature forest, though no significant (P > 0.1) difference could be detected between recently burned and unburned young forest. Rs was measured in recently burned boreal jack pine fire scar age categories that differed in their burn history and there was a significant difference in Rs T,M between previously 32 v 16 year old (P = 0.000) and previously 32 v 59 year old (P = 0.044) scars. There was a strong significant exponential increase in S R T,M with time since fire (r2 = 0.999; P = 0.006) for the chronosequence 0, 16 and 59 years post fire, and for all these age categories, Rs T,M was significantly different from one another (P < 0.05). The Joint UK Land Environment Simulator (JULES) was used to model vegetation re-growth over successional time at Sharpsand Creek, though it appeared to perform poorly in simulating leaf area index and canopy height. JULES probably over estimated heterotrophic Rs at Sharpsand Creek when Ts corrected simulated values were compared with measured Rs T,M. The results of this study contribute to a better quantitative understanding of Rs in boreal jack pine fire scars and will facilitate improvements in C cycle modelling. Further work is needed in quantifying autotrophic and heterotrophic contributions to soil respiration in jack pine systems, monitoring soil respiration for extended time periods after fire and improving the ability of JULES to simulate successional vegetation re-growth.

Les forêts tropicales constituent le principal réservoir de biodiversité et de carbone (C). Cependant, la plupart des forêts tropicales, en particulier les forêts de Bornéo en Asie du Sud-Est, subissent une pression intense et sont menacées par des activités anthropiques telles que l'exploitation forestière, l'industrie minière l’agriculture et la conversion en plantations industrielles. En 2010, la superficie des forêts de production de Bornéo était de 26,8 millions d’ha (environ 36% de la superficie totale de l’île, dont 18 millions ha (environ 24%) déjà exploités. Par conséquent, les forêts de production occupent donc une place importante à Bornéo et jouent un rôle essentiel dans la compensation des biens fournis et la maintenance des services écosystémiques, tels que la conservation du C et de la biodiversité.L’exploitation sélective réduit la biomasse aérienne et souterraine par l’élimination de quelques grands arbres, et augmente les stocks de bois mort par des dommages collatéraux. En créant des trouées dans la canopée, le microclimat dans les sous-étages et au sol change localement et accélèrent la décomposition de la litière et de la matière organique. L'importance des dégâts, de l'ouverture de la canopée et de la rapidité du rétablissement du C s'est avéré principalement liée à l'intensité de l'exploitation forestière. Cependant, les évaluations empiriques de l'effet à long terme de l'intensité de l'exploitation forestière sur l'équilibre du C dans les forêts de production restent rares.La présente thèse se concentre principalement sur l'évaluation de l'effet à long terme de l'intensité de l'exploitation forestière sur la séquestration de carbone dans une forêt à Diptérocarpées de Nord Bornéo (District de Malinau, Kalimantan Nord) exploitée en 1999/2000. Cinq principaux réservoirs de C, à savoir le C aérien dans les arbres vivants (AGC), le C souterrain dans les arbres vivants (BGC), le bois mort, la litière et le C organique du sol (SOC) ont été estimés le long d’un gradient d'intensité d'exploitation (0-57% de la biomasse perdue).Nos résultats ont montré que les stocks totaux de C, 16 ans après l'exploitation, variaient de 218 à 554 Mg C ha-1 avec une moyenne de 314 Mg C ha-1. Une différence de 95 Mg C ha-1 a été observée entre une faible intensité d'exploitation forestière (<2,1% de la biomasse initiale perdue) et une intensité d'exploitation élevée (>19%). La plus grande partie du C (environ 77%) était présente dans les arbres vivants, suivie par les stocks du sol (15%), les stocks de bois mort (6%) et une fraction mineure des stocks de litière (1%). L'empreinte de l'intensité de l'exploitation forestière était encore détectable 16 ans après l'exploitation et a été le principal facteur expliquant la réduction des AGC>20, BGC>20, du bois mort et des stocks de C et une augmentation du bois mort. L'intensité de l'exploitation expliquait à elle seule 61%, 63%, 38% et 48% des variations des AGC>20, BGC>20, du bois mort et des stocks de C totaux, respectivement. L'intensité de l'abattage a également réduit considérablement les stocks de SOC dans la couche supérieure de 30 cm. Pour l'ensemble des stocks de SOC (0-100 cm), l'influence de l'intensité de l'exploitation était encore perceptible, en conjonction avec d'autres variables.Nos résultats quantifient l'effet à long terme de l'exploitation forestière sur les stocks de C forestier, en particulier sur les AGC et les bois morts. L'intensité élevée de l'exploitation forestière (réduction de 50% de la biomasse initiale) a réduit les stocks totaux de C de 27%. La récupération de l'AGC était plus faible dans les parcelles d'intensité d'exploitation forestière élevée, ce qui suggère une résilience plus faible de la forêt à l'exploitation forestière. Par conséquent, une intensité d'exploitation forestière inférieure à 20%, devrait être envisagé afin de limiter l'effet à long terme sur les AGC et le bois mort. / Tropical forests are a major reservoir of biodiversity and carbon (C), playing a pivotal role in global ecosystem function and climate regulation. However, most of the tropical forests, especially Bornean forests in Southeast Asia, are under intense pressure and threatened by anthropogenic activities such as logging, mining industry, agriculture and conversion to industrial plantation. In 2010, the area of production forests in Borneo was 26.8 million ha (approx. 36% of the total land area of Borneo) including 18 million ha (approx. 24%) of logged forests. Production forests are thus emerging as a dominant land-use, playing a crucial role in trading-off provision of goods and maintenance of ecosystem services, such as C and biodiversity retention.Selective logging is known to reduce both above- and below-ground biomass through the removal of a few large trees, while increasing deadwood stocks through collateral damages. By creating large gaps in the canopy, microclimates in the understory and on the forest floor change locally speeding up the decomposition of litter and organic matter. The extent of incidental damages, canopy openness, as well as the speed of C recovery, was shown to be primarily related to logging intensity. However, empirical evaluations of the long-term effect of logging intensity on C balance in production forests remain rare.The present thesis aims to assess the long-term effect of logging intensity on C sequestration in a north Bornean Dipterocarp forests (Malinau District, North Kalimantan) logged in 1999/2000. Five main C pools, namely above-ground (AGC) and below-ground (BGC) carbon in living trees, deadwood, litter, and soil organic carbon (SOC) were estimated along a logging intensity gradient (ranging from 0 to 57% of initial biomass removed).Our result showed that total C stocks 16 years after logging, ranged from 218-554 Mg C ha-1 with an average of 314 Mg C ha-1. A difference of 95 Mg C ha-1 was found between low logging intensity (<2.1% of initial biomass lost) and high logging intensity (>19%). Most C (approx. 77%) was found in living trees, followed by soil (15%), deadwood (6%), and a minor fraction in litter (1%). The imprint of logging intensity was still detectable 16 years after logging, and logging intensity thus was the main driver explaining the reduction of AGC>20, BGC>20, deadwood, and total C stocks and an increase in deadwood. Solely, logging intensity explained 61%, 63%, 38%, and 48% of variations of AGC>20, BGC>20, deadwood, and total C stocks, respectively. Logging intensity also significantly reduced SOC stocks in the upper 30 cm layer. For total SOC stocks (0-100 cm), the negative influence of logging intensity was still perceptible, being significant in conjunction with other variables.Our results quantify the long-term effect of logging on forest C stocks, especially on AGC and deadwood. High logging intensity (50% reduction of initial biomass) reduced total C stocks by 27%. AGC recovery was lower in high logging intensity plots, suggesting lowered forest resilience to logging. Our study showed that maintaining logging intensity, below 20% of the initial biomass, limit the long-term effect of logging on AGC and deadwood stocks.

Σκοπός: Η μελέτη είχε ως σκοπό την διερεύνηση της ασφάλειας και της αποτελεσματικότητας των sirolimus-eluting stent, σε σχέση με τα απλά μεταλλικά stent, στα πλαίσια αγγειοπλαστικής των κνημιαίων αγγείων, σε ασθενείς με χρόνια κρίσιμη ισχαιμία του κάτω άκρου. Πρόκειται για μια προοπτική ελεγχόμενη, κλινική μελέτη με διπλό σκέλος. Τα stent τοποθετήθηκαν σε περιπτώσεις μη ικανοποιητικής αγγειοπλαστικής (δηλ. σε περιπτώσεις ελαστικής επαναφοράς-υπολειμματικής στένωσης >30% και σε περιπτώσεις διαχωρισμού). Οι ασθενείς ελέγχθηκαν κλινικά και αγγειογραφικά στο εξάμηνο και στο 1 έτος. Ασθενείς και μέθοδοι: 29 ασθενείς, εκ των οποίων 8 γυναίκες και 21 άνδρες, με μέση ηλικία τα 68,7 έτη υποβλήθηκαν σε αγγειοπλαστική στα κνημιαία αγγεία, με απλά μεταλλικά stent, ομάδα Β. Σε αυτή την ομάδα τοποθετήθηκαν απλά stent σε 65 αλλοιώσεις, εκ των οποίων 38 στενώσεις και 27 αποφράξεις σε συνολικά 40 κνημιαία αγγεία. Άλλοι 29 ασθενείς, 8 γυναίκες και 21 άνδρες, με μέση ηλικία τα 68,8 έτη αντιμετωπίστηκαν με sirolimus-eluting stent, ομάδα S. Σε αυτή την ομάδα αντιμετωπίστηκαν 66 αλλοιώσεις εκ των οποίων 46 στενώσεις και 20 αποφράξεις, σε 41 συνολικά αγγεία. Οι ασθενείς επανελέγχθηκαν κλινικά και με ενδαρτηριακή αγγειογραφία στους 6 μήνες και στο 1 έτος, μετά την αρχική επέμβαση. Έγινε στατιστική ανάλυση των αποτελεσμάτων. Αποτελέσματα: Οι συνοδές νόσοι ήταν περισσότερες στην ομάδα S (όπως η συμπτωματική νόσος από την καρδιά και τις καρωτίδες, καθώς και η υπερλιπιδαιμία, p<0.05). Η τεχνική επιτυχία ήταν 96,6% (28/29 άκρα) στην ομάδα Β έναντι 100% (29/29 άκρα) στην ομάδα S (p=0.16) Στον επανέλεγχο εξαμήνου: Η βατότητα ήταν 68,1% στην ομάδα Β και 92,0% στην ομάδα S, (p<0.002). Τα μεγαλύτερα ποσοστά βατότητας των sirolimus-eluting stent, μετά από πολυπαραγοντική regression analysis είχαν OR 5.625, με 95% CI 1.711- 18.493, που ήταν στατιστικά σημαντικό (p=0.004). Η δυαδική επαναστένωση εντός του stent ήταν 55,3% ενώ η επαναστένωση στα άκρα του stent ήταν 66,0% στους ασθενείς με τα απλά μεταλλικά stent. Αντιθέτως τα ποσοστά στους ασθενείς με sirolimus-eluting stent ήταν 4,0% και 32,0% αντίστοιχα. Συγκεκριμένα η επαναστένωση εντός του stent είχε OR 0.067, με 95% CI 0.021-0.017, και η επαναστένωση στα άκρα του stent είχε OR 0.229 με 95% CI 0.099-0.533. Και τα δύο ήταν ήταν στατιστικά σημαντικά με p<0.001 και p=0.001, αντίστοιχα. Τα συνολικά ποσοστά επανεπέμβασης (TLR) στο εξάμηνο ήταν 17,0% στην ομάδα Β έναντι 4,0% στην ομάδα S, (OR 0.057, με 95% CI 0.008-0.426). Το αποτέλεσμα ήταν επίσης στατιστικά σημαντικό υπέρ των sirolimus stent. (p=0.02) Η διάσωση του άκρου ήταν 100% και στις δύο ομάδες. Η θνησιμότητα και ο ελάσσων ακρωτηριασμός στο εξάμηνο ήταν 6,9% και 17,2% στην ομάδα Β έναντι 10,3% και 3,4% στην ομάδα S (p=0.32 και p=0.04, αντίστοιχα). Στον επανέλεγχο έτους: Τα sirolimus-eluting stent σχετίζoνταν και πάλι με καλύτερη πρωτογενή βατότητα (OR 10.401, με 95% CI 3.425-31.589, p<0.001) και σημαντικά μειωμένη δυαδική επαναστένωση εντός του stent (OR 0.156, με 95% CI 0.060-0.407, p<0.001), καθώς και στα άκρα του stent. (OR 0.089, με 95% CI 0.023-0.349, p=0.001) Τα ποσοστά επανεπέμβασης στις βλάβες (TLR) ήταν πολύ μικρότερα στην ομάδα του sirolimus (OR 0.238, με 95% CI 0.067-0.841, p=0.026) . Δεν υπήρξαν στατιστικά σημαντικές διαφορές ανάμεσα στις δύο ομάδες Β και S όσον αφορά στα ποσοστά θνησιμότητας 10,3% έναντι 13,8%, στη διάσωση του άκρου 100% έναντι 96% και στους ελάσσονες ακρωτηριασμούς 17,2% έναντι 10,3% αντίστοιχα. Συμπεράσματα: Τα sirolimus-eluting stents περιορίζουν την ενδοθηλιακή υπερπλασία στα κνημιαία αγγεία. Η εφαρμογή τους έχει ως αποτέλεσμα την σημαντική μείωση των ποσοστών επαναστένωσης και μειώνει την ανάγκη για επανεπεμβάσεις. / Aim : The purpose of our study was to investigate the 6-month and 1-year angiographic and clinical outcome in the setting of a controlled clinical study. The study examined the safety and relative effectiveness of sirolimus-eluting stents opposed to conventional metal stents, in the infrapopliteal vessels, in patients with critical limb ischemia (CLI). The stents were used in a bail-out setting during infrapopliteal endovascular procedures, i. e. stenting was carried out in cases of suboptimal angioplasty results (recoil - residual stenosis >30%, or in cases of dissection, after angioplasty). Patients and Methods: Twenty-nine patients comprising 8 women and 21 men with a mean age of 68.7 years were submitted to infrapopliteal revascularization with conventional (bare) metal stents, called group B. In these patients 65 lesions were treated with bare stents, of whom 38 stenoses and 27 occlusions, in a total of 40 infrapopliteal vessels. Another 29 patients, again 8 women and 21 men, with a mean age of 68.8 years were treated with sirolimus-eluting stents, named group S. There were 66 lesions in this group with 46 of them stenoses and 20 occlusions, in a total of 41 arteries. Patients were followed-up with clinical examination and intrarterial angiography 6 months and 1 year after the procedure. Both results were subsequently analyzed statistically. 135 Results: Co morbidities like symptomatic cardiac and carotid disease, as well as hyperlipidemia were more prominent in group S (p<0.05). Technical success was 96.6% (28/29 limbs) in group B against 100.0% (29/29 limbs) in group S (p=0.16). During 6-month patient follow-up: Primary patency was 68.1% in group B opposed to 92.0% in group S (p<0.002). Sirolimus-eluting stents exhibited higher primary patency with OR 5.625 and 95% CI 1.711-18.493, which was statistically significant (p=0.004). Binary in-stent restenosis rate was 55.3% while in-segment restenosis was 66.0%, in patients who had received bare metal stents. In opposition the respective restenosis rates, in patients with sirolimus-eluting stents were 4.0% and 32.0%. Diminished in-stent (OR 0.067 with 95% CI 0.021-0.017) and insegment (OR 0.229 with 95% CI 0.099-0.533) binary restenosis were both statistically significant with p values being p<0.001 and p=0.001 respectively. Collective target lesion re-intervention (TLR) at 6 month follow-up was 17.0% in group B against 4.0% (OR 0.057 with 95% CI 0.008-0.426) in group S, which proved again statistically significant for sirolimus stents (p=0.02). Six-month limb salvage rate was 100% in both groups. Six-month mortality and minor amputation rates were respectively 6.9% and 17.2%, in group B versus 10.3% and 3.4%, in group S (p=0.32 and p=0.04, respectively). During 1-year patient follow-up: 136 SES were still related with better primary patency rate (OR 10.401 with 95% CI 3.425-31.589, p<0.001) and considerably lesser events of in-stent binary restenosis (OR 0.156, 95% CI 0.060-0.407, p<0.001) as well as insegment (OR 0.089, 95% CI 0.023-0.349, p=0.001) binary restenosis. Target lesion re-intervention (TLR), was much lower in the SES patients group during 1-year follow-up (OR 0.238 with 95% CI 0.067-0.841, p=0.026) . At 1 year follow-up there were no statistically significant differences among group B and group S regarding mortality (10.3% against 13.8%), limb salvage rates (100% vs. 96%) and minor amputation (17.2% vs. 10.3%). Conclusions: Sirolimus-eluting stents appear to limit intimal hyperplasia in the infrapopliteal vessels. The use of sirolimus-eluting stents decreases considerably restenosis rates in the infrapopliteal vessels and reduces the need for repeat interventions

This thesis offers a micro-level analysis of labour and women’s organizing in the context of globalization through the case study of the Comité Fronterizo de Obrer@s (CFO) from 1978 to 2009. We will see how one organization’s journey can give us insights into the complexities of local organizing and transnational networking in the context of globalization. This case study can be seen as a lens through which we can examine the changing context of labour and women’s organizing in the distinct maquiladora environment. My work positions itself in the “globalization from above” and “globalization from below” debate, specifically around the question of transnational social movements that form the “globalization from below” category in the context of a political economy analysis. However, where my thesis differs from a more traditional analysis of the resistance to globalization, such as that found in the global justice movements or alter-globalization movements, is in its focus on the complexities of organizing at the local level and the pressures that these local organizations feel from “above” from their transnational partners. What this thesis adds to the literature are the stories from the actual members of the organization, about the structure, the decision-making process of their organization, the role of the leadership and the connections between the local organizing and the transnational civil society partners. The complex history of an organization that has been there since the beginning of the maquiladora industry allows us a better understanding of the changing conditions and struggles these workers have faced. This journey through the history of the CFO, the richness of this empirical data encompassing more than 30 years of organizing in the maquiladora zone of Northern Mexico also allows us to explore “globalization from below” through different lens. This thesis brings in a micro-detail analysis of a specific organization in a specific context where we can see clearly transnational civil society linkages and the impact of globalizing capitalist neoliberal economy. As such, this research can offer us new insights into the intricacies of local-global linkages and thus contribute to an area often neglected or underdeveloped in international relations (IR).
