Welfare Effects of Food Miles Labels
We assessed the consumer welfare effects of two generic food miles labels: carbon dioxide (CO2) emission label and number of miles label. Using data from a choice experiment, our results generally suggest that a mandatory labeling policy for either type of label would have a positive welfare effect on both informed and uninformed consumers. However, a label informing consumers about the number of miles the food product has travelled provides greater positive welfare effects than a label informing consumers about the amount of CO2 emission.welfare effect, generic food miles labelling programs, choice experiment, Italy., Agricultural and Food Policy, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Marketing,

Itâs a Matter of Time! CEO Turnover and Corporate Turnarounds in Italy
This paper examines whether CEO turnover affects company performance and the optimal time for CEO renewal during a turnaround process. Results, derived from data collected from Italian companies, highlight the necessity of introducing the new CEO before beginning an insolvency procedure. A later appointment can reduce his/her impact, probably due to the difficulty of managing negotiations with the creditors. Moreover, we show a positive and significant relationship between CEO turnover and the likelihood of a bankrupt firm re-emerging from an insolvency procedure. The analysis was based on the traditional logit model and more modern approaches like the random forest and the AdaBoost models, combined with the SHAP technique. Overall, our findings provide valuable insight for all company stakeholders, whose interests are significantly impacted by its default
Axion-like Particles from Hypernovae
It was recently pointed out that very energetic subclasses of supernovae
(SNe), like hypernovae and superluminous SNe, might host ultra-strong magnetic
fields in their core. Such fields may catalyze the production of feebly
interacting particles, changing the predicted emission rates. Here we consider
the case of axion-like particles (ALPs) and show that the predicted large scale
magnetic fields in the core contribute significantly to the ALP production, via
a coherent conversion of thermal photons. Using recent state-of-the-art SN
simulations including magnetohydrodynamics, we find that if ALPs have masses
, their emissivity via magnetic
conversions is over two orders of magnitude larger than previously estimated.
Moreover, the radiative decay of these massive ALPs would lead to a peculiar
delay in the arrival times of the daughter photons. Therefore, high-statistics
gamma-ray satellites can potentially discover MeV ALPs in an unprobed region of
the parameter space and shed light on the magnetohydrodinamical nature of the
SN explosion.Comment: 6 pages, 3 Figure
Maternal Phylogenetic Relationships and Genetic Variation among Rare, Phenotypically Similar Donkey Breeds
The mitochondrial DNA (mtDNA) D-loop of endangered and critically endangered breeds has been studied to identify maternal lineages, characterize genetic inheritance, reconstruct phylogenetic relations among breeds, and develop biodiversity conservation and breeding programs. The aim of the study was to determine the variability remaining and the phylogenetic relationship of Martina Franca (MF, with total population of 160 females and 36 males), Ragusano (RG, 344 females and 30 males), Pantesco (PT, 47 females and 15 males), and Catalonian (CT) donkeys by collecting genetic data from maternal lineages. Genetic material was collected from saliva, and a 350 bp fragment of D-loop mtDNA was amplified and sequenced. Sequences were aligned and evaluated using standard bioinformatics software. A total of 56 haplotypes including 33 polymorphic sites were found in 77 samples (27 MF, 22 RG, 8 PT, 19 CT, 1 crossbred). The breed nucleotide diversity value (Ï) for all the breeds was 0.128 (MF: 0.162, RG: 0.132, PT: 0.025, CT: 0.038). Principal components analysis grouped most of the haplogroups into two different clusters, I (including all haplotypes from PT and CT, together with haplotypes from MF and RG) and II (including haplotypes from MF and RG only). In conclusion, we found that the primeval haplotypes, haplogroup variability, and a large number of maternal lineages were preserved in MF and RG; thus, these breeds play putative pivotal roles in the phyletic relationships of donkey breeds. Maternal inheritance is indispensable genetic information required to evaluate inheritance, variability, and breeding programs

Increased Incidence of Thyroid Dysfunction and Autoimmunity in Patients with Vernal Keratoconjunctivitis
Hormones may play a role in the pathophysiology of vernal keratoconjunctivitis (VKC). An increased incidence of thyroid autoantibodies was recently observed in VKC, although there were no data on thyroid function. Two hundred and eighty-eight patients (202 males, 86 females; range 5.5 to 16.9 years) with VKC were evaluated and compared with 188 normal age- and sex-matched subjects. In all subjects, serum concentrations of free T4, TSH, thyroperoxidase, thyroglobulin, and TSHr autoantibodies were evaluated. In VKC, the family history of thyroid diseases showed no significant differences compared to the controls (9.4 versus 8.6%), whereas the family history of autoimmune diseases was significantly higher (13.2% versus 6.3%; P<0.05). Subclinical hypothyroidism was diagnosed in 6.6% (versus 1.6% of the controls; P<0.05) and overt hypothyroidism in 0.7% (versus 0.0% of the controls; P=NS). Finally, 5.2% of patients were positive for thyroid autoantibodies, which were significantly higher with respect to the controls (0.5%, P<0.05). In the patients positive for thyroid autoantibodies, 80% showed a sonography pattern that suggested autoimmune thyroiditis. Thyroid function and autoimmunity abnormalities are frequently present in children with VKC. Children with VKC should be screened for thyroid function and evaluated for thyroid autoimmunity
