Barriers to transformative adaptation: Responses to flood risk in Ireland
Barriers to climate change adaptation have received increased attention in recent years as researchers and policymakers attempt to understand their complex and interdependent nature and identify strategies for overcoming them. To date however, there is a paucity of research on barriers to transformative adaptation. Using two case studies of flood risk management from Ireland we identify and characterize barriers to transformative adaptation. Qualitative semi-structured interviews were conducted with key stakeholders connected to proposed transformative strategies in Skibbereen, County Cork and Clontarf, County Dublin. Across both case studies, where transformative strategies failed to materialize, we highlight three significant barriers that impede transformation including: (i) social and cultural values, particularly place attachment and identity; (ii) institutional reliance on technical expertise which fails to look beyond traditional technocratic approaches and; (iii) institutional regulatory practices. Findings illustrate that where social or institutional barriers emerge, transformation may more likely succeed through a series of incremental changes. This research has practical implications for future adaptation planning as facilitating transformation through incrementalism requires flexible adaptation strategies that are responsive to changing social values over time. While focused on flood risk management, our findings have applicability for other sectors adapting to climate change

Harnessing Wicked Problems in Multi-stakeholder Partnerships
Despite the burgeoning literature on the governance and impact of cross-sector partnerships in the past two decades, the debate on how and when these collaborative arrangements address globally relevant problems and contribute to systemic
change remains open. Building upon the notion of wicked problems and the literature on governing such wicked problems, this paper defines
harnessing problems in multi-stakeholder partnerships (MSPs) as the approach of taking into account the nature of the problem and of organizing governance processes accordingly. The paper develops an innovative analytical framework that conceptualizes MSPs in terms of three governance processes (deliberation, decision-making and enforce-ment) harnessing three key dimensions of wicked problems (knowledge uncertainty, value conflict and dynamic complexity).
The Roundtable on Sustainable Palm Oil provides an illustrative case study on how this analytical framework describes and explains organizational change in partnerships from a problem-based perspective. The framework can be used to better understand and predict the complex relationships between MSP governance processes, systemic change and societal problems, but also as a guiding tool in (re-)organizing governance processes to continuously re-assess the problems over time and address them accordingly
The role of the mitochondria and the endoplasmic reticulum contact sites in the development of the immune responses
Abstract Mitochondria and endoplasmic reticulum (ER) contact sites (MERCs) are dynamic modules enriched in subset of lipids and specialized proteins that determine their structure and functions. The MERCs regulate lipid transfer, autophagosome formation, mitochondrial fission, Ca2+ homeostasis and apoptosis. Since these functions are essential for cell biology, it is therefore not surprising that MERCs also play a critical role in organ physiology among which the immune system stands by its critical host defense function. This defense system must discriminate and tolerate host cells and beneficial commensal microorganisms while eliminating pathogenic ones in order to preserve normal homeostasis. To meet this goal, the immune system has two lines of defense. First, the fast acting but unspecific innate immune system relies on anatomical physical barriers and subsets of hematopoietically derived cells expressing germline-encoded receptors called pattern recognition receptors (PRR) recognizing conserved motifs on the pathogens. Second, the slower but very specific adaptive immune response is added to complement innate immunity. Adaptive immunity relies on another set of specialized cells, the lymphocytes, harboring receptors requiring somatic recombination to be expressed. Both innate and adaptive immune cells must be activated to phagocytose and process pathogens, migrate, proliferate, release soluble factors and destroy infected cells. Some of these functions are strongly dependent on lipid transfer, autophagosome formation, mitochondrial fission, and Ca2+ flux; this indicates that MERCs could regulate immunity

Treatment outcome and toxicity of intensity-modulated (chemo) radiotherapy in stage III non-small cell lung cancer patients
Abstract Purpose The aim of this retrospective cohort study was to assess treatment outcome, and acute pulmonary and esophageal toxicity using intensity modulated (sequential/concurrent chemo)radiotherapy (IMRT) in locally advanced stage III non-small cell lung cancer (NSCLC). Methods and materials Eighty-six patients with advanced stage NSCLC, treated with either IMRT only (66 Gy) or combined with (sequential or concurrent) chemotherapy were retrospectively included in this study. Overall survival and metastasis-free survival were assessed as well as acute pulmonary and esophageal toxicity using the RTOG Acute Radiation Morbidity Scoring Criteria. Results Irrespective of the treatment modality, the overall survival rate for patients receiving 66 Gy was 71% (±11%; 95% CI) after one year and 56% (±14%) after two years resulting in a median overall survival of 29.7 months. Metastasis-free survival was 73% (±11%) after both one and two years. There were no statistically significant differences between the treatment groups. Treatment related esophageal toxicity was significantly more pronounced in the concurrent chemoradiotherapy group (p = 0.013) with no differences in pulmonary toxicity. Conclusions This retrospective cohort study in advanced non-small cell lung cancer patients shows that IMRT is an effective technique with acceptable acute toxicity, also when (sequentially or concomitantly) combined with chemotherapy.</p
