The Effect of Revenue and Geographic Diversification on Bank Performance

This paper investigates the effect of revenue and geographic diversification on bank performance, also on a risk adjusted basis. Using an unbalanced panel dataset of 3,002 observations relative to Italian banks for the period 2006-2011, the core question is to analyse the effect of geographic and functional diversification across and within both interest and non-interest income and their effect on some principal performance measures. Furthermore in our study we analyse whether certain type of institutions are better able to reap the benefits of diversification analysing performance implications for different categories of banks and if the results have been affected by the financial crisis. The main results suggest that revenue and geographical diversification play a role in determining bank performance. The relative effects appear, however, to be different between mutual and not-mutual banks suggesting different business strategies for different banks. Moreover, in the after crisis period, banks that have been less penalized in terms of riskadjusted profit are those characterised by a gretare focus on non interest income component and the ones more geographically diversified. These findings have strategic implications both for bank managers, regulators and supervisors for the consequences on banks\u2019 performance and stability

Sustainable development and european banks: A non-financial disclosure analysis

none4noThis paper aims at contributing to the debate on the relationships between the European financial sector and sustainable development. Using a non-financial disclosure analysis of 262 European banks, the research sought, first, to investigate the "scope" of the contribution of European banks to the Sustainable Development Goals (SDGs) and, second, to explore the factors that seem to differentiate the SDGs approach among banks. The results show that country of origin, legal system, and adoption of an integrated report seem to differentiate banks in terms of contribution to the SDGs. The business model and stock exchange listing, conversely, do not seem to represent discriminatory factor in the contribution of banks toward the SDGs. The study can be useful for managers and decision makers to develop policies to support organizations in contributing to the SDGs.openCosma S.; Venturelli A.; Schwizer P.; Boscia V.Cosma, S.; Venturelli, A.; Schwizer, P.; Boscia, V

Isotope partitioning between cow milk and farm water: A tool for verification of milk provenance

Rationale: The oxygen and hydrogen isotope compositions of the water component of the milk from nine Italian dairy farms were studied together with the farm water for one year. The aim was to verify the importance of farm water and seasonal temperature variation on milk isotope values and propose mathematical relations as new tools to identify the milk origin. Methods: Milk was centrifuged to separate the solids and then distilled under vacuum to separate water. δ(18O/16O) and δ(2H/1H) analyses of the water molecules were carried out using a water equilibrator online with a mass spectrometer. For oxygen and hydrogen isotope determination, water was equilibrated with pure CO2 for 7.5 h and with pure H2 for 5 h, respectively. The isotope ratio value is indicated with δ (expressed on the VSMOW/SLAP scale) as defined by IUPAC. Results: The average annual isotope value of milk at the different cattle sheds is mostly related to the farm water suggesting that the drinking water is the most important factor influencing the isotopic values of the milk water. The milk/water fractionation factor correlates with the milking time and, thus, the seasonal temperature is best described by a 4th order polynomial regression line. A two-level check model was used to verify the milking provenance. Conclusions: This study shows that it is essential to analyze both milk and farm water to indicate provenance. A two-step verification tool, based on the difference between the measured and calculated δ(18O/16O)M values, and the difference between the calculated and estimated milk-water fractionation factors, allowed the source determination of milk. Both conditions must be met if the milk is considered to be from the Parmigiano-Reggiano production region. Although this approach was developed for this region, it can easily be tested and adapted to other dairy production areas

Acute treatment of stroke (except thrombectomy)

Purpose of Review: The management of patients with acute stroke has been revolutionized in recent years with the advent of new effective treatments. In this rapidly evolving field, we provide an update on the management of acute stroke excluding thrombectomy, looking to recent, ongoing, and future trials.Recent Findings: Large definitive trials have provided insight into acute stroke care including broadening the therapeutic window for thrombolysis, alternatives to standard dose alteplase, the use of dual antiplatelet therapy early after minor ischemic stroke, and treating elevated blood pressure in intracerebral hemorrhage. Further ongoing and future trials are eagerly awaited in this ever-expanding area.Summary: Although definitive trials have led to improvements in acute stroke care, there remains a need for further research to improve our understanding of pathophysiological mechanisms underlying different stroke types with the potential for treatments to be tailored to the individual

Limits on the low energy antinucleon-nucleus annihilations from the Heisenberg principle

We show that the quantum uncertainty principle puts some limits on the effectiveness of the antinucleon-nucleus annihilation at very low energies. This is caused by the fact that the realization a very effective short-distance reaction process implies information on the relative distance of the reacting particles. Some quantitative predictions are possible on this ground, including the approximate A-independence of antinucleon-nucleus annihilation rates.Comment: 10 pages, no figure

Recruitment strategies and interventions to increase participation in lung cancer screening programmes: A systematic review protocol

IntroductionDespite strong evidence for the efficacy of low-radiation dose CT (LDCT) in reducing lung cancer (LC) mortality, implementing LC screening (LCS) programmes remains a challenge. We aim to systematically review the evidence on the strategies used to recruit the adult population at risk of LC to LDCT within LCS programmes and to estimate the effectiveness of interventions identified, used to reach the potentially eligible population, increase participation and informed choice, and ensure equitable access.Methods and analysisThis sequential systematic literature review will consist of three steps: (1) a scoping review of existing strategies and organisational models for LCS; (2) selecting papers reporting relevant outcomes (test coverage, screening participation and informed choice) and comparing results among different models; (3) a systematic review of interventions implemented to increase participation in LCS programmes. Each step will follow the methodological guidelines provided by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Data sources include electronic databases such as Medline (PubMed version), Embase, CINAHL (Ebsco version), Scopus and Cochrane CENTRAL. The search will be limited to studies published from January 2000 to March 2023 in English, Italian, French, Spanish, Serbian and Croatian language. Findings will be synthesised quantitatively and qualitatively as appropriate. Risk of bias assessment will be only applied to studies selected in the second and third steps. The quality of evidence will be summarised for each outcome using the Grading Recommendation Assessment, Development and Evaluation methodology.Ethics and disseminationGiven that this is a review of existing literature, ethics approval is not required. The results will be published in peer-reviewed scientific journals and presented at relevant conferences. The findings of this review will help guide health authorities in organising LCS programmes and developing recommendations, policies, and actions at national and regional levels.PROSPERO registration numberCRD42023408357

Symbolic dynamics for the NN-centre problem at negative energies

We consider the planar $N$-centre problem, with homogeneous potentials of degree -\a<0, \a \in [1,2). We prove the existence of infinitely many collisions-free periodic solutions with negative and small energy, for any distribution of the centres inside a compact set. The proof is based upon topological, variational and geometric arguments. The existence result allows to characterize the associated dynamical system with a symbolic dynamics, where the symbols are the partitions of the $N$ centres in two non-empty sets

Exercise and nutritional interventions on sarcopenia and frailty in heart failure: a narrative review of systematic reviews and meta-analyses

The purpose of this review is to describe the present evidence for exercise and nutritional interventions as potential contributors in the treatment of sarcopenia and frailty (i.e. muscle mass and physical function decline) and the risk of cardiorenal metabolic comorbidity in people with heart failure (HF). Evidence primarily from cross-sectional studies suggests that the prevalence of sarcopenia in people with HF is 37% for men and 33% for women, which contributes to cardiac cachexia, frailty, lower quality of life, and increased mortality rate. We explored the impact of resistance and aerobic exercise, and nutrition on measures of sarcopenia and frailty, and quality of life following the assessment of 35 systematic reviews and meta-analyses. The majority of clinical trials have focused on resistance, aerobic, and concurrent exercise to counteract the progressive loss of muscle mass and strength in people with HF, while promising effects have also been shown via utilization of vitamin D and iron supplementation by reducing tumour necrosis factor-alpha (TNF-a), c-reactive protein (CRP), and interleukin-6 (11-6) levels. Experimental studies combining the concomitant effect of exercise and nutrition on measures of sarcopenia and frailty in people with HF are scarce. There is a pressing need for further research and well-designed clinical trials incorporating the anabolic and anti-catabolic effects of concurrent exercise and nutrition strategies in people with HF
