Comparative research on violent conflict in the Basque Country and Ireland has yielded a sizable body of published academic work. Less well explored is the relationship between conflict transformation and cross-border cooperation in that specific comparative context. This paper provides a comparative examination of Third (not for profit) sector cross-border cooperation as conflict transformation in the Basque (France/Spain) and Irish (UK/Ireland) border regions. To what extent does cross-border cooperation contribute to peacebuilding in the two last violent ethnonationalist conflicts in Western Europe? The comparison is based on the premise that the EU played a different role in both cases. In the Irish case, the EU contributed to the institutionalization of a peace process that included cross-border cooperation between third sector organizations among the policy instruments contributing to conflict transformation. In the Basque case, the unilateral renunciation of violence by ETA (Euskadi eta Askatasuna) in 2010 did not generate the consistent involvement of the EU in a comparable institutional peace process. However, some third sector organizations used EU instruments for cross-border economic, social and cultural cooperation between France and Spain in order to reinforce their cross-border networks, which indirectly impacted on conflict transformation. The effectiveness of this cross-border cooperation for conflict transformation is assessed comparatively. To what extent does this increase in cross-border cooperation “from below” connect to wider institutional and social processes of conflict transformation in Ireland and the Basque Country? Crucially, does the strengthening of cross-border relations on shared issues mollify or sharpen existing identity cleavages? Also considered is the sustainability of such cooperation in these regions in light of the less favourable post-2004 EU funding environment, and the post-2008 economic and political turmoil affecting the relevant EU member states, especially Ireland and Spain.

Cross-border cooperation as conflict transformation provides a potential strategy for the European Union (EU) to help realise its founding peacebuilding objective. A wealth of cross-border cooperation activity sponsored by the EU spans a quarter of a century. Although the conflict transformation capacity of that cooperation is questionable in some border regions there is evidence to suggest that it has delivered peacebuilding dividends in other border regions. However, EU cross-border cooperation as conflict transformation faces a number of significant twenty-first century challenges including: ghost borders of the communal imagination; EU external border securitization; perceptions of EU and Russian empire-building; and the Mediterranean transmigrant/refugee crisis. It is argued that these challenges pose significant obstacles to EU cross-border cooperation as conflict transformation and undermine the peacebuilding objective of European integration.

Malignant Triton tumor (MTT) is a malignant peripheral nerve sheath tumor showing rhabdomyoblastic differentiation. It is considered a high-grade neoplasm with poor outcome. This report describes an MTT appearing in the oral cavity. On histologic examination the encapsulated lesion was composed of interlacing fascicles of spindle cells and scattered, large, strap-like pleomorphic cells with abundant eosinophilic cytoplasm. No cross striations were seen. Examination of levels through the tissue showed a total of only 4 normal mitoses and no necrosis. Immunohistochemistry demonstrated diffuse S100 positivity in the spindle cells. The large pleomorphic cells were weakly positive for alpha-sarcomeric actin and myoglobin, although variably but strongly positive for desmin. Management involved a small en bloc resection of the maxilla. After 33 months there was no sign of recurrence or distant metastasis. It was concluded that low-grade variants of MTT occur that do not have an aggressive clinical course.

Purpose: To describe sequential phacoemulsification-intraocular lens (IOL) implantation-posterior capsulorhexis-anterior vitrectomy in the management of phakic malignant glaucoma. Methods: Twenty consecutive patients (25 eyes) with phakic malignant glaucoma were enrolled at the Zhongshan Ophthalmic Center, Sun Yat-sen University. All patients underwent phacoemulsification, IOL implantation and posterior capsulorhexis together with anterior vitrectomy via a clear corneal paracentesis. Visual acuity, intraocular pressure (IOP), anterior chamber depth (ACD), surgical complications and medications required after the surgery were recorded. Results: After surgery, the mean LogMAR visual acuity and ACD increased significantly (visual acuity from -1.56 ± 1.17 to -0.54 ± 0.81, p < 0.001; ACD from 0.367 ± 0.397 mm to 2.390 ± 0.575 mm, p < 0.001), and mean IOP decreased significantly (from 39.6 ± 10.6 mm Hg to 14.5 ± 4.1 mmHg, p < 0.001). No serious perioperative complications occurred, and only five eyes required topical glaucoma medications after surgery. Conclusion: Combined phacoemulsification-IOL implantation-posterior capsulorhexis-anterior vitrectomy surgery is a safe and effective method for treating patients with phakic malignant glaucoma. © 2012 The Authors.

Modeling the spectral emission of low-charge iron group ions enables the diagnostic determination of the local physical conditions of many cool plasma environments such as those found in H II regions, planetary nebulae, active galactic nuclei etc. Electron-impact excitation drives the population of the emitting levels and, hence, their emissivities. By carrying-out Breit-Pauli and intermediate coupling frame transformation (ICFT) R-matrix calculations for the electron-impact excitation of Fe$^{2+}$ which both use the exact same atomic structure and the same close-coupling expansion, we demonstrate the validity of the application of the powerful ICFT method to low-charge iron group ions. This is in contradiction to the finding of Bautista et al. [Ap.J.Lett, 718, L189, (2010)] who carried-out ICFT and Dirac R-matrix calculations for the same ion. We discuss possible reasons.

This article is a reflexive and critical examination of recent empirical research on effective practice in the management and ‘transformation’ of contested urban space at sectarian interfaces in Belfast. By considering the development of interfaces, the areas around them and policy responses to their persistence, the reality of contested space in the context of ‘peace building’ is apparent; with implications for local government as central to the statutory response. Belfast has developed an inbuilt absence of connectivity; where freedom of movement is particularly restricted and separation of contested space is the policy default position. Empirical research findings focus attention on the significance of social and economic regeneration and fall into three specific areas that reflect both long-term concerns within neighbourhoods and the need for adequate policy responses and action ‘on the ground’. Drawing on Elden and Sassen we reconfigure the analytical framework by which interfaces are defined, with implications for policy and practice in post-conflict Belfast. Past and current policy for peace-building in Northern Ireland, and transforming the most contested space, at interfaces in Belfast, is deliberately ambiguous and offers little substance having failed to advance from funding-led linguistic compliance to a sustainable peace-building methodology.

Cette recherche poursuit l'objectif général d'analyser la transformation des pratiques professionnelles des enseignants du secondaire à l'égard des élèves en difficulté intégrés en classe régulière suite à leur participation au dispositif des cercles d'apprentissage et d'inclusion (CAI). La problématique met en évidence les changements de paradigmes associés aux multiples réformes du système de l'éducation et les difficultés auxquelles sont confrontés les enseignants depuis l'instauration de la nouvelle Politique de l'adaptation scolaire au Québec. Les nouvelles visées ministérielles prônent désormais une éducation de qualité pour tous. La notion d'équité est à la base des actions qui doivent guider les pratiques de l'école inclusive. Cependant, les écrits sur le sujet soulignent le manque de connaissances des enseignants pour adapter leurs pratiques professionnelles aux élèves en difficulté intégrés dans leur classe (Gaudreau, Legault, Brodeur, Hurteau, Dunberry, Séguin, Legendre, 2008; MacKay, 2006). Ces auteurs suggèrent à cet égard, la nécessité d'implanter dans les milieux des dispositifs de formation continue axés sur l'acquisition de connaissances quant aux processus d'apprentissage des élèves, aux pratiques pédagogiques différenciées et aux stratégies favorables aux apprentissages. La méthodologie utilisée s'inscrit dans une démarche de co-construction des savoirs. (Desmarais, Boyer et Dupont, 2005) avec des enseignants désireux de travailler sur l'amélioration de leurs pratiques professionnelles à l'égard des élèves en difficulté intégrés en classe régulière au secondaire. Ainsi, des groupes de réflexions portant sur l'analyse de l'expérience vécue par les enseignants ont permis d'offrir un accompagnement et un cadre défini pour la collecte de données (Boudreault et Kalubi, 2006). Des entrevues semi-dirigées ont complété notre collecte de données à la fin du projet afin de préciser et de nuancer les propos recueillis lors des groupes de réflexion. Les résultats obtenus nous ont permis d'identifier certaines conditions à mettre en place dans l'accompagnement des enseignants en exercice et de mieux comprendre les difficultés relatives à un tel dispositif.
