No Lavrentiev gap for some double phase integrals
We prove the absence of the Lavrentiev gap for non-autonomous functionals F(u) := integral(Omega) f(x, Du(x)) dx,where the density f(x, z) is alpha-Holder continuous with respect to x; x is an element of Omega subset of R^n; f satisfies the (p, q)-growth conditions |z|^p <= f(x, z) <= L (1 + |z|^q),where 1 < p < q < p(n+alpha)/n, and it can be approximated from below by suitable densities f_k.We prove the absence of the Lavrentiev gap for non-autonomous functionalsF(u) := integral(Omega) f(x, Du(x)) dx,where the density f(x, z) is alpha-Holder continuous with respect to x is an element of Omega subset of R-n, it satisfies the (p, q)-growth conditionsvertical bar z vertical bar(p) <= f(x, z) <= L (1 + vertical bar z vertical bar(q)),where 1 < p < q < p(n+alpha/n), and it can be approximated from below by suitable densities f(k)

AN IMPACT ASSESSMENT OF THE FUTURE CAP REFORM ON THE ITALIAN TOMATO SECTOR
The Health Check (HC) document traces the path for a new revision of the CAP. The communication content can be summarised in the following points: decoupling at regional and not at historical level, a more intensive modulation mechanism differentiated according to the total volume of subsidy received by the farm and a new implementation of the art. 69. The aim of this paper is to assess the effect of the HC on the farms producing fruits and vegetables in Italy, with a particular emphasis on the processed tomato production. The model based on the PMP approach simulates the regionalisation mechanism and the new modulation per brackets. The analysis carried out on a FADN sample of farms located in Emilia-Romagna region highlights as the HC new measures affect the farm economic performances but not the input allocation choice. The flat rate doesn’t produce perturbation in the relative convenience of the crops maintaining unchanged the degree of substitution among activities. Only when the CAP mechanism moves from a coupling scenario to a total decoupling one and in the case of a variation in price levels the modifications inside the production plan are evident.Future CAP reforms, Tomato sector, CAP assessment, Agricultural and Food Policy, Political Economy, Q10, Q18,
HEALTH CHECK AND FARM EFFICIENCY: A COMPARATIVE ASSESSMENT OF FOUR EUROPEAN AGRICULTURAL REGIONS
The European Commission has always considered the Common Agricultural Policy (CAP) as a dynamic political tool that aims to link the agricultural sector with the evolving of the economic, financial, social and political dynamics that distinguish the Member States of the European Union. From this standpoint, the Health Check (HC) is much more than a simple assessment of the state of health of European agriculture; it is a drawing up of the “new rules” that are to manage the relations between farms and the market, on which the future efficiency and survival of the said farms and the production sectors that characterise entire European agricultural regions will depend. In this context, the aim of this paper is to present and analyse the "innovations" of the future CAP compared to the current subsidy management system. In particular, the impact of the modifications of the HC – relative to the methods for funding farms due to the transition to the regionalised Single (Farm) Payment Scheme (SPS) and to the new rates of modulation – on the competitiveness of farms specialised in certain production sectors of four European regions will be considered: Emilia- Romagna (IT), Kassel (DE), Anatoliki-Makedonia-Thraki (GR) and Ostra Mallansverige (SE). The assessment of the impact of the HC on the competitiveness of farms is made by taking the technical efficiency index, estimated by a DEA model, as a proxy for the capacity of farms to use factors of production to their best advantage with respect to the farming system adopted and hence to be able to be competitive with other enterprises in the same sector. At the same time, the analysis of the impact of the HC measures is carried out using the “generalised” Positive Mathematical Programming method in order to enable a comparison between European regions. The integration of the two methods applied to the data of the European FADN enables an in-depth assessment of the impacts and a critical evaluation of the goals that the Community reform proposal is expected to attain.Health Check, Single Farm Payments, Technical Efficiency Index, DEA model, Positive Mathematical Programming., Agricultural and Food Policy, Political Economy, Research Methods/ Statistical Methods, Q10, Q12, Q18,

Outlook on next-generation probiotics from the human gut
Probiotics currently available on the market generally belong to a narrow range of microbial species. However, recent studies about the importance of the gut microbial commensals on human health highlighted that the gut microbiome is an unexplored reservoir of potentially beneficial microbes. For this reason, academic and industrial research is focused on identifying and testing novel microbial strains of gut origin for the development of next-generation probiotics. Although several of these are promising for the prevention and treatment of many chronic diseases, studies on human subjects are still scarce and approval from regulatory agencies is, therefore, rare. In addition, some issues need to be overcome before implementing their wide application on the market, such as the best methods for cultivation and storage of these oxygen-sensitive taxa. This review summarizes the most recent evidence related to NGPs and provides an outlook to the main issues that still limit their wide employment

The food-gut axis: lactic acid bacteria and their link to food, the gut microbiome and human health
Lactic acid bacteria (LAB) are present in foods, the environment and the animal gut, although fermented foods (FFs) are recognized as the primary niche of LAB activity. Several LAB strains have been studied for their health-promoting properties and are employed as probiotics. FFs are recognized for their potential beneficial effects, which we review in this article. They are also an important source of LAB, which are ingested daily upon FF consumption. In this review, we describe the diversity of LAB and their occurrence in food as well as the gut microbiome. We discuss the opportunities to study LAB diversity and functional properties by considering the availability of both genomic and metagenomic data in public repositories, as well as the different latest computational tools for data analysis. In addition, we discuss the role of LAB as potential probiotics by reporting the prevalence of key genomic features in public genomes and by surveying the outcomes of LAB use in clinical trials involving human subjects. Finally, we highlight the need for further studies aimed at improving our knowledge of the link between LAB-fermented foods and the human gut from the perspective of health promotion
