Effects of climate change on Romanian mountain tourism: Are they positive or mostly negative?

Climate change represents a real threat for the winter sport resorts, especially those situated at low altitudes and without any diversification of the tourism product. Mountain tourism represents a real attraction for the holidays and for short weekends being mostly visited by tourists in summer and winter season, which make them more vulnerable to the lack of snow in the cold season, floods, storms or even heat waves. This paper has two main objectives, firstly to measure the impact of the climate change on tourism demand for Romanian mountain tourism, and secondly to identify sustainable solutions for adaptation of vulnerable mountain resorts, such as Sinaia, one of the most known winter sport resorts in Romania. First, the authors will identify the impacts of climate change on Romanian mountain tourism, starting with the effect of the temperature increase, snow depth variation and the extreme weather events occurring in mountain resorts on tourist flows. Positive and negative effects of climate change will be identified, and starting from the results, the authors will present necessary measures to transform the Romanian mountain tourism in an adaptive destination.CNCSIS-UEFISCU - PN II-RU 94/2010, Contract no. 30/28.07.201

Effect of Torulaspora delbrueckii Yeast on the Anthocyanin and Flavanol Concentrations of Cabernet franc and Pinotage Wines

Pinotage and Cabernet franc grape must were inoculated with Saccharomyces cerevisiae and Torulasporadelbrueckii yeasts. Differences in colour were observed between Pinotage (S. cerevisiae) and Pinotage (T.delbrueckii) wines, whereas differences in berry and herbaceous character were observed between Cabernetfranc (S. cerevisiae) and Cabernet franc (T. delbrueckii) wines. Mouthfeel properties between treatmentsfor both wines were not significantly different. Overall quality was slightly higher in wines inoculatedwith T. delbrueckii compared to wines inoculated with S. cerevisiae. Anthocyanins and flavanols measuredin Pinotage wines made with T. delbrueckii were higher compared to Pinotage must inoculated with S.cerevisiae. Cabernet franc wines made with S. cerevisiae were higher in anthocyanin glycoside and flavanolconcentrations compared to Cabernet franc wines made with T. delbrueckii. Insignificant differencesin acetylated and coumarylated anthocyanins were evident between Cabernet franc (S. cerevisiae) andCabernet franc (T. delbrueckii) wines. Principal component analysis showed that epigallocatechin gallate,epicatechin gallate, procyanidin B2, peonidin 3-O-glucoside, delphinidin 3-(6-acetyl) glucoside, petunidin3-(6-acetyl) glucoside, malvidin 3-(6-acetyl) glucoside and malvidin 3-O-glucoside concentrationswere highest in Pinotage wines inoculated with T. delbrueckii. Cabernet franc wines inoculated with S.cerevisiae yeasts were highest in malvidin 3-(6-p-coumaroyl) glucoside, petunidin 3-(6-p-coumaroyl)glucoside, petunidin 3-O-glucoside, epicatechin gallate and epigallocatechin gallate concentrations. Totalanthocyanins were highest in Pinotage (S. cerevisiae) wines and Cabernet franc (T. delbrueckii) wines.Flavanols were highest in Pinotage (T. delbrueckii) and Cabernet franc (S. cerevisiae) wines. It is evidentfrom the results that yeast species has an impact on the flavonoid concentrations within a grape variety

On the net reproduction rate of continuous structured populations with distributed states at birth

We consider a nonlinear structured population model with a distributed recruitment term. The question of the existence of non-trivial steady states can be treated (at least!) in three different ways. One approach is to study spectral properties of a parametrized family of unbounded operators. The alternative approach, on which we focus here, is based on the reformulation of the problem as an integral equation. In this context we introduce a density dependent net reproduction rate and discuss its relationship to a biologically meaningful quantity. Finally, we briefly discuss a third approach, which is based on the finite rank approximation of the recruitment operator.Comment: To appear in Computers and Mathematics with Application

Gender differences in the association between adiposity and probable major depression: a cross-sectional study of 140,564 UK Biobank participants

<b>Background</b><p></p> Previous studies on the association between adiposity and mood disorder have produced contradictory results, and few have used measurements other than body mass index (BMI). We examined the association between probable major depression and several measurements of adiposity: BMI, waist circumference (WC), waist-hip-ratio (WHR), and body fat percentage (BF%).<p></p> <b>Methods</b><p></p> We conducted a cross-sectional study using baseline data on the sub-group of UK Biobank participants who were assessed for mood disorder. Multivariate logistic regression models were used, adjusting for potential confounders including: demographic and life-style factors, comorbidity and psychotropic medication.<p></p> <b>Results</b><p></p> Of the 140,564 eligible participants, evidence of probable major depression was reported by 30,145 (21.5%). The fully adjusted odds ratios (OR) for obese participants were 1.16 (95% confidence interval (CI) 1.12, 1.20) using BMI, 1.15 (95% CI 1.11, 1.19) using WC, 1.09 (95% CI 1.05, 1.13) using WHR and 1.18 (95% CI 1.12, 1.25) using BF% (all p <0.001). There was a significant interaction between adiposity and gender (p = 0.001). Overweight women were at increased risk of depression with a dose response relationship across the overweight (25.0-29.9 kg/m2), obese I (30.0-34.9 kg/m2), II (35.0-39.9 kg/m2) and III (≥40.0 kg/m2) categories; fully adjusted ORs 1.14, 1.20, 1.29 and 1.48, respectively (all p < 0.001). In contrast, only obese III men had significantly increased risk of depression (OR 1.29, 95% CI 1.08, 1.54, p = 0.006).<p></p> <b>Conclusion</b><p></p> Adiposity was associated with probable major depression, irrespective of the measurement used. The association was stronger in women than men. Physicians managing overweight and obese women should be alert to this increased risk

Research and Innovation As a Catalyst For Food System Transformation

Background Food systems are associated with severe and persistent problems worldwide. Governance approaches aiming to foster sustainable transformation of food systems face several challenges due to the complex nature of food systems. Scope and approach In this commentary we argue that addressing these governance challenges requires the development and adoption of novel research and innovation (R&I) approaches that will provide evidence to inform food system transformation and will serve as catalysts for change. We first elaborate on the complexity of food systems (transformation) and stress the need to move beyond traditional linear R&I approaches to be able to respond to persistent problems that affect food systems. Though integrated transdisciplinary approaches are promising, current R&I systems do not sufficiently support such endeavors. As such, we argue, we need strategies that trigger a double transformation – of food systems and of their R&I systems. Key Findings and Conclusions Seizing the opportunities to transform R&I systems has implications for how research is done – pointing to the need for competence development among researchers, policy makers and society in general – and requires specific governance interventions that stimulate a systemic approach. Such interventions should foster transdisciplinary and transformative research agendas that stimulate portfolios of projects that will reinforce one another, and stimulate innovative experiments to shape conditions for systemic change. In short, a thorough rethinking of the role of R&I as well as how it is funded is a crucial step towards the development of the integrative policies that are necessary to engender systemic change – in the food system and beyond

Constitutional patriotism

Constitutional patriotism is a political theory that seeks to provide an explanation for the sense of ownership that most individuals have towards their national constitutional system. Specifically, constitutional patriotism assumes that free-thinking individuals involved in a discussion over the common good will reach an agreement that is perceived, at least by those involved in the debate, as having normative value. The awareness that such a deliberative process has historically been a part of the constitutional system also induces a sense of ownership of past historical accommodations of constitutional principles. The shared perception of being part of historically grounded institutions within a deliberative democracy is sometimes called the ‘normative surplus effect’ or ‘normative spill-over effect’ of the deliberative process. The theory, in its current form, was proposed by Jürgen Habermas and Jean-Werner Müller. Debates over the common good might take place informally or within the state’s institutions. Pell-mell informal debates, with few exceptions, have a limited effect on amending constitutional norms. Yet, the prerogative to openly discuss laws and policies legitimised by constitutional norms is normally sufficient to develop an inner sense of belonging to a constitutional system. Deliberative debates within public institutions (e.g. parliaments and courts) are more likely to change the functioning of a constitutional system, but they are, by way of comparison to informal political discussions, normally constrained by the system of rules that regulate representative democracy and the administration of justice. Thus, the theory of constitutional patriotism provides an explanatory model for the historical development of a democratic constitutional system. As one of the most persuasive explanatory theories of modern pluralist democracy, constitutional patriotism has attracted a series of well-articulated critiques. It has been suggested, for instance, that constitutional patriotism might not provide a plausible model of social integration for international organisations such as the European Union (EU). In this essay, I will provide an overview of the theory and a selection of its critiques

A Systems Approach to Research and Innovation for Food System Transformation

This policy brief of the European Union (EU) Think Tank – part of the FIT4FOOD2030 Coordination and Support Action (CSA) of the FOOD 2030 initiative – is a response and contribution to growing pleas for a ‘systems approach’ to transform food systems for Food and Nutrition Security (FNS) for present and future generations. This policy brief specifically focusses on the necessity of the adoption of a systems approach to Research and Innovation (R&I) in order to foster the transformation of food systems

Research and Innovation Supporting the Farm to Fork Strategy of the European Commission

Key Research and Innovation Questions on Engaging Consumers in the Delivery of FOOD 2030

Food system transformation requires major changes in food consumption practices. Consumers could play central roles to stimulate these changes, which needs to be fully recognized. Multi-stakeholder R&I efforts should focus more on the interactions between individual, contextual and policy factors influencing consumption patterns, with specific attention to the dynamic character of food environments. Consumers should be empowered and engaged in decision making, through co-design, co-creation, co-implementation and co-assessment
