We’re Small Enough to Close but Big Enough to Divide: The Complexities of the Nova Scotia School Review Process

Through interviews conducted in the fall of 2013 and winter of 2014, this paper presents a portrait of the various issues faced by community activists in fighting to keep their small rural schools open amidst constraints, most notably, provincial budget cuts and low enrolment numbers in rural areas. At the same time, school board members seeking to close small schools in rural areas faced their own sets of constraints. Participants were asked to discuss: their experiences in the small schools review process, their suggestions for policy design and implementation, and their notions around what small schools mean to rural sustainability and future economic development. Throughout these interviews, the participants from both contexts highlighted the struggles they faced during the review process and the impact of school closures on their children, their communities, and themselves. In addition to metrocentric (Green & Corbett, 2013) assumptions faced by the activists in the school review and closure process, there were additional issues concerning the configurations of people with different orientations as they attempted to participate in a democratic dialogue within the school closure process.Cet article présente, par le biais d’entrevues ayant eu lieu à l’automne 2013 et l’hiver 2014, un aperçu des divers enjeux qu’affrontent les activistes communautaires dans leur lutte pour maintenir ouvertes leurs petites écoles rurales dans le contexte de contraintes, notamment les compressions budgétaires du gouvernement provincial et le faible nombre d’inscriptions dans les milieux ruraux. En contrepartie, les membres des conseils scolaires voulant fermer les petites écoles dans les milieux ruraux faisaient face à leurs propres contraintes. On a demandé aux participants de discuter des éléments suivants : leurs expériences lors du processus d’examen des petites écoles; leurs suggestions quant aux nouvelles politiques et à leur mise en œuvre; et leurs idées sur le rôle des petites écoles dans la durabilité rurale et le développement économique à l’avenir. Tout au long des entrevues, les participants des deux contextes ont souligné les luttes qu’ils ont affrontées pendant le processus d’examen, ainsi que l’impact des fermetures d’écoles sur leurs enfants, leurs communautés et eux-mêmes. Les participants ont évoqué, en plus des suppositions « métrocentriques » (Green & Corbett, 2013) auxquelles ont dû faire face les activistes pendant les processus d’examen et de fermeture, des enjeux impliquant les configurations de gens avec différentes orientations qui tentaient de participer au dialogue démocratique au sein du processus de fermeture des écoles.

Small Schools in a Big World: Thinking About a Wicked Problem

The position of small rural schools is precarious in much of rural Canada today. What is to be done about small schools in rural communities which are often experiencing population decline and aging, economic restructuring, and the loss of employment and services? We argue this issue is a classic "wicked" policy problem. Small schools activists have a worldview that is focused on maintaining infrastructure and even community survival, while school boards are mandated to focus on the efficient provision of educational services across wider geographies. Is it even possible to mitigate the predictable conflict and zero-sum games that arise with the decision to close small schools? That is the subject of this paper, which draws on poststructural and actor network theory. We suggest that wicked problems cannot be addressed satisfactorily through formulas and data-driven technical-rational processes. They can only be addressed through flexible, dialogical policy spaces that allow people who have radically different worldviews to create dynamic, bridging conversations. Fundamentally, we argue that what is required are new spaces and modes of governance that are sufficiently networked, open, and flexible to manage the complexity and the mutability of genuinely participatory democracy.De nos jours, la situation des petites écoles rurales est précaire dans beaucoup de milieux ruraux au Canada. Que faire des petites écoles dans les milieux ruraux souvent aux prises avec une population vieillissante et en déclin, une restructuration économique, et une perte d’emplois et de services? Nous soutenons que cette situation est un problème classique de politique « pernicieuse ». Les activistes des petites écoles ont une vision du monde axée sur le maintien de l’infrastructure, voire la survie communautaire, alors que les conseils scolaires sont chargés de miser sur la prestation efficace de services éducationnels sur de plus grandes étendues. Est-il même possible de mitiger le conflit prévisible et les jeux à somme nulle qui découlent de la décision de fermer de petites écoles? Voilà le sujet de cet article, qui puise dans la théorie post-structurale et la théorie du réseau d’acteurs. Nous proposons que les problèmes pernicieux ne peuvent être abordés de façon satisfaisante par les formules et les processus technico-rationnels axés sur les données. Ils ne peuvent être résolus que par des politiques souples et dialogiques qui permettent aux gens avec des visions du monde radicalement différentes de créer des conversations dynamiques qui appuient le rapprochement. Dans le fond, nous militons en faveur de nouveaux espaces et de nouveaux modes de gouvernance qui sont suffisamment réseautés, ouverts et souples pour gérer la complexité et la mutabilité d’une démocratie authentiquement participative.

Suppression of Superconductivity by Twin Boundaries in FeSe

Low-temperature scanning tunneling microscopy and spectroscopy are employed to investigate twin boundaries in stoichiometric FeSe films grown by molecular beam epitaxy. Twin boundaries can be unambiguously identified by imaging the 90{\deg} change in the orientation of local electronic dimers from Fe site impurities on either side. Twin boundaries run at approximately 45{\deg} to the Fe-Fe bond directions, and noticeably suppress the superconducting gap, in contrast with the recent experimental and theoretical findings in other iron pnictides. Furthermore, vortices appear to accumulate on twin boundaries, consistent with the degraded superconductivity there. The variation in superconductivity is likely caused by the increased Se height in the vicinity of twin boundaries, providing the first local evidence for the importance of this height to the mechanism of superconductivity.Comment: 6 pages, 7 figure

Spectroscopic scanning tunneling microscopy insights into Fe-based superconductors

In the first three years since the discovery of Fe-based high Tc superconductors, scanning tunneling microscopy (STM) and spectroscopy have shed light on three important questions. First, STM has demonstrated the complexity of the pairing symmetry in Fe-based materials. Phase-sensitive quasiparticle interference (QPI) imaging and low temperature spectroscopy have shown that the pairing order parameter varies from nodal to nodeless s\pm within a single family, FeTe1-xSex. Second, STM has imaged C4 -> C2 symmetry breaking in the electronic states of both parent and superconducting materials. As a local probe, STM is in a strong position to understand the interactions between these broken symmetry states and superconductivity. Finally, STM has been used to image the vortex state, giving insights into the technical problem of vortex pinning, and the fundamental problem of the competing states introduced when superconductivity is locally quenched by a magnetic field. Here we give a pedagogical introduction to STM and QPI imaging, discuss the specific challenges associated with extracting bulk properties from the study of surfaces, and report on progress made in understanding Fe-based superconductors using STM techniques.Comment: 36 pages, 23 figures, 229 reference

Promoter polymorphism of the erythropoietin gene in severe diabetic eye and kidney complications

Significant morbidity and mortality among patients with diabetes mellitus result largely from a greatly increased incidence of microvascular complications. Proliferative diabetic retinopathy (PDR) and end stage renal disease (ESRD) are two of the most common and severe microvascular complications of diabetes. A high concordance exists in the development of PDR and ESRD in diabetic patients, as well as strong familial aggregation of these complications, suggesting a common underlying genetic mechanism. However, the precise gene(s) and genetic variant(s) involved remain largely unknown. Erythropoietin (EPO) is a potent angiogenic factor observed in the diabetic human and mouse eye. By a combination of case–control association and functional studies, we demonstrate that the T allele of SNP rs1617640 in the promoter of the EPO gene is significantly associated with PDR and ESRD in three European-American cohorts [Utah: P = 1.91 × 10−3; Genetics of Kidneys in Diabetes (GoKinD) Study: P = 2.66 × 10−8; and Boston: P = 2.1 × 10−2]. The EPO concentration in human vitreous body was 7.5-fold higher in normal subjects with the TT risk genotype than in those with the GG genotype. Computational analysis suggests that the risk allele (T) of rs1617640 creates a matrix match with the EVI1/MEL1 or AP1 binding site, accounting for an observed 25-fold enhancement of luciferase reporter expression as compared with the G allele. These results suggest that rs1617640 in the EPO promoter is significantly associated with PDR and ESRD. This study identifies a disease risk-associated gene and potential pathway mediating severe diabetic microvascular complications
