Risoluzione delle situazioni di stallo decisionale nelle società di capitali. Composizione degli interessi e profili sistematici.
Full text linkQuando si verificano situazioni di stallo, rompendosi l’ordinario processo decisionale dell’impresa, di frequente si generano conseguenze negative per la società coinvolta nell’impasse, per i suoi stakeholders, nonché per l’intero sistema economico. Questa condizione, che può investire tanto l’organo amministrativo che quello assembleare, si manifesta di consueto in società costituite al fine di dare seguito a joint ventures oppure nel caso, molto frequente in paesi come l’Italia, di imprese familiari, dove i soci affiancano spesso alla partecipazione al capitale un coinvolgimento diretto nella gestione dell’impresa. Soci o amministratori possono voler privilegiare ciascuno scelte diverse sulle politiche aziendali future, non necessariamente alla ricerca di benefici individuali, ma anche nell’interesse del migliore sviluppo o della sopravvivenza della società. Ove però lo stallo riguardi decisioni di cruciale importanza e interrompa il funzionamento dell’organo societario che lo riguarda la società potrebbe arrivare allo scioglimento, anche ai sensi di quanto disposto dall’art. 2484, comma 1, n. 3, c.c., distruggendo irreversibilmente valore. Tuttavia, come sottolineato dalla giurisprudenza, l’irreversibilità che deve caratterizzare il dissidio tra i soci, per poter rilevare quale causa di scioglimento della società, deve escludersi quando vi siano strumenti giuridici che, ove applicati, consentano di superare la situazione di paralisi. Si individuano, così, una serie di tecniche contrattuali, solitamente definite “clausole antistallo” o “deadlock breaking provisions”, che possono essere incluse nei patti sociali o parasociali volte a risolvere impasse decisionali.
L’obiettivo del presente lavoro è di mettere in luce l’importanza di queste clausole nella pianificazione statutaria delle società, al contempo vagliando i confini dell’autonomia negoziale nel disciplinarle e verificando la compatibilità delle stesse con l’ordinamento. Si procederà, innanzitutto, ad una definizione e classificazione delle situazioni di stallo tenendo in considerazione le conseguenze dello stesso nel governo dell’impresa, con successivo approfondimento delle principali tecniche diffuse in ambito societario per il suo superamento. Seguirà una valutazione delle principali criticità che possono generarsi per le parti coinvolte a seguito dell’inserimento di tali previsioni, specie in situazioni di forti asimmetrie informative, ulteriormente accentuate dalla scarsa definizione dei rapporti societari e dalla ridotta separazione tra proprietà e gestione che caratterizza le società familiari e di minore dimensione nell’ambito delle quali queste clausole trovano più frequente applicazione. Infine, sarà importante esaminare come le interpretazioni proposte e i principi identificati nella citata analisi si relazionano con le clausole antistallo più comuni, prestando attenzione all’efficacia e alla correttezza operativa di tali disposizioni
Relationship between Human Aging Muscle and Oxidative System Pathway
Full text linkAgeing is a complex process that in muscle is usually associated with a decrease in mass, strength, and velocity of contraction. One of the most striking effects of ageing on muscle is known as sarcopenia. This inevitable biological process is characterized by a general decline in the physiological and biochemical functions of the major systems. At the cellular level, aging is caused by a progressive decline in mitochondrial function that results in the accumulation of reactive oxygen species (ROS) generated by the addition of a single electron to the oxygen molecule. The aging process is characterized by an imbalance between an increase in the production of reactive oxygen species in the organism and the antioxidant defences as a whole. The goal of this review is to examine the results of existing studies on oxidative stress in aging human skeletal muscles, taking into account different physiological factors (sex, fibre composition, muscle type, and function)
Anti-nutrient components and metabolites with health implications in seeds of 10 common bean (Phaseolus vulgaris L. and Phaseolus lunatus L.) landraces cultivated in southern Italy
No full textCommon beans (Phaseolus vulgaris L.) provide an inexpensive food rich in macronutrients such as protein and starch, important micronutrients such as iron, and also a number of other stored bioactive compounds (phytates, polyphenols, tannins, raffinosaccharides, lectins, protease and α-amylase inhibitors, saponins, etc.) endowed with positive health implications through their antioxidant, anti-tumour or phyto-oestrogenic activity. They also produce negative dietary effects such as interference with micronutrient absorption, protein digestibility or glucose metabolism, or even direct toxic effects (lectins). Analysis of the levels of these compounds in seeds of local and underexploited common bean varieties and landraces may reveal traits of interest for promoting nutrition and preserving health, and in addition allow breeders to use them in genetic improvement programmes to modify the levels of specific compounds in new common bean varieties. In the present work, 10 bean populations belonging to 7 highly appreciated southern Italian landraces were analysed. The seeds of one of them, “Poverello di Rotonda AF”, was found to accumulate remarkable levels of 4 health-promoting components such as quercetin (24.2 μg/g), genistein (21.6 μg/g), soysapogenin B (433 μg/g) and oleanolic acid (11.9 μg/g), while “Tabacchino” contained very high amounts of iron (131 μg/g) and three health-promoting components: kaempferol (61.0 μg/g), oleanolic acid (12.3 μg/g) and condensed tannins (2.36 mg/g). A level of variation high enough to be exploited for breeding purposes was found for 7 out of 15 biochemical parameters studied
EVALUATION OF A PHYTO-SUPPLEMENT EFFICACY AS ADJUVANT IN REDUCING BODY WEIGHT AND FAT MASS IN OVERWEIGHT WOMEN
No full textOverweight and obesity affect more than 66%
of the adult population and are associated with a variety
of chronic diseases. Weight loss has then beneficial effects
in reducing health risks associated with chronic diseases. In
recent decades, weight management has evolved into a multidisciplinary
approach, combining low-calorie diets with
physical activity and nutritional supplementation. This could
help weight loss by inducing a reduction in caloric intake,
an increased lipolysis or a reduction of the nervous system
feedback of hunger sensation. The study presented in this work
aimed at evaluating the efficacy of a dietary supplemental
containing phloridzin, isoflavones and probiotics (Re-Code®),
as an adjuvant in reducing body weight and fat mass in
slightly overweight women. Phyto-supplement consumption
was included in a body weight reduction programme including
a mild hypocaloric diet and moderate daily physical activity.
A randomised, double-blinded, placebo-controlled trial
was conducted on 40 slightly overweight women aged 30 to
54. Women taking the phyto-supplement showed greater
reductions in body weight, fat mass and waist, thigh and
buttock circumference than the control group. Moreover, the
used phyto-supplement proved to be an effective adjuvant in
body weight and fat mass reduction when associated with
both a mild low-calorie diet and moderate physical activity in
overweight women

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Triacylglycerol content, productivity and fatty acid profile in Scenedesmus acutus PVUW12
Full text linkA detailed lipid characterization of Scenedesmus acutus PVUW12, with emphasis on the evaluation of triacylglycerols (TAGs) as a biodiesel feedstock, is presented. When algal cells were grown in nitrogen-free medium (N stress), a lipid increase was detected that was mainly due to TAG accumulation. In situ fluorescence measurements allowed the kinetics and extent of neutral lipid accumulation to be followed. Under N stress, the productivity of total lipids and TAGs increased significantly (80.99 and 63.74 mg L−1 day−1, respectively) compared with controls (29.51 and 16.23 mg L−1 day−1, respectively). Monounsaturated fatty acids were the major fraction and increased further (49.74 %) in stressed cells, with oleic acid as the most abundant compound (46.97 %). The polyunsaturated fatty acid composition of this algal oil appears to meet the European Standard EN 14214. These results indicate that S. acutus oil meets the requirements for its use as a biodiesel feedstock. Since this strain was also proposed for wastewater bioremediation, this opens up the possibility of its use in an integrated system combined with biofuel production.Fil: Damiani, Maria Cecilia.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
