Unicuique suum. Per una rinnovata cultura della certezza giuridica
No full textOgni cosa al suo posto is the latest book by Massimo Luciani, in which the author
argues the case for the need for a “restoration” of the constitutional order
through the recovery of the role of Parliament with respect to the other
two traditional powers, namely the Government and the Judiciary. In this
perspective, some of the main themes of contemporary legal reflection are
touched upon, starting with the conception of the legal phenomenon and the
methodological status of the science of law, with an approach that transcends
the boundaries of specific disciplines by opening up to a high and wide-ranging
cultural vision
Opening the black-box of graduates’ horizontal skills: diverging labour market outcomes in Italy
No full textThis paper assesses labour market outcomes associated with the acquisition of different graduate competences in the Italian labour markets particularly focusing on ‘soft skills’ developed during HE programs. By using a classification of graduate jobs that distinguishes between different horizontal skills, namley managerial and communication skills, the paper conducts an empirical analysis of the benefits of being employed in such occupations having completed a degree program. These benefits are assessed across time, referring to the period following the crisis and to most recent available data. Results show that only ‘communication’ skills provide higher benefits than discipline-related skills. Moreover, the higher education system seems not to provide higher education graduates with distinctive ‘managerial’ competences compared to non-graduate workers suggesting that these types of social skills can be developed through alternative learning paths, such as work-based experience or other extra-curricular activities
The geographical origin of birds migrating through Alps: a stable isotope approach (δ2H)
No full textEvery year hundreds of thousands of European birds travel after their breeding season through Europe to reach their wintering areas. Geographic barriers such as seas, deserts or high mountain chains force migrants into constrained flyways that obligate populations of different geographic origins to aggregate and follow the ecological corridors they find along their journeys (Cox 2010). Alps represent an ecological barrier to many bird species that migrate from central and northern breeding latitudes to southern wintering destinations, such as Mediterranean basin or trans-Saharan Africa. To cross such barrier, birds and especially small Passerines are obligated to follow the geographical morphology of the alpine valleys and use ecological bottle-necks such as mountain passes to change valley and prosecute their journey to south (Bruderer and Jenni 1990). The majority of small songbirds are migrating through Alps between August and November, showing two peaks of abundance, the first in August for trans-Saharan specimeasues and the second in October for intra-Palearctic species. Since 1996 ISPRA and CNI (Centro Nazionale di Inanellamento) are conducting a monitoring activity of bird migration through Alps, named ‘Progetto Alpi’ project and coordinated by MUSE of Trento and ISPRA. The project involves several ringing stations that work simultaneously between August and November from east to west across Italian Alps (Pedrini et al. 2008, 2012). The project aims to understand trends and timing of migration of several songbirds. Hence, it becomes crucial to know the geographic origin of populations affecting the Italian alpine migratory corridor. We measured hydrogen isotope ratios in feathers sampled in ‘Bocca di Caset’ ringing station (Trentino province) on two Passerines, European robin Erithacus rubecula and Pied flycatcher Ficedula hypoleuca. We used a known ‘local feather / precipitation δ2H’ regression to transform measured δ2H into values comparable to the mean-annual isoscape for δ2H in Europe (Hobson et al. 2004, Bowen et al. 2005). We than calculated the assignment using IsoMAP to produce probability surfaces of geographic assignments (Bowen et al. 2014). We refined obtained origin areas with prior information given by a recovery dataset and the known breeding range of the species
Evidence for two waves of induction of DNA enzymes in stimulated human lymphocytes.
No full textThe stimulation of human lymphocytes with phytohaemoagglutinin induces the appearance or increase of several enzymes of DNA metabolism [Pedrini etal., Biochem. Biophys. Res. Comm., 47:1221(1972)]. With long times of stimulation, two phenomena are observed; an increase in the levels of DNA polymerase, of a DNase acting on single-stranded DNA, and of an endonuclease, occurring between the third and fourth day, in parallel with a wave of DNA synthesis;a second wave of increase of the same enzymes and of DNA ligase,occurring between the fifth and eight day when the DNA replication rate, as measured by thymidine-pulses, has decreased to values close to the background
Psychological impact of carotid endarterectomy: a review of the studies.
No full textRassegna sistematica degli studi scientifici pubblicati su PubMed, EMBASE, PsychoInfo, Google Schoolar dal 1990 al 2007 in relazione all'impatto psicologico dell'endarterectomia carotidea (CEA). In particolare sono stati esaminati tutti gli studi e le rassegne che valutano l'impatto della CEA sulle funzioni cognitive, sulla depressione e sulla qualità di vita percepita
Cognitive and emotional changes following carotid endarterectomy (CEA): Preliminary results.
No full textCognitive changes after Carotid Endarterectomy
No full textThe aim of this study was to investigate changes in cognitive
function following carotid endarterectomy (CEA).
In 74 asymptomatic CEA patients cognitive function,
depression, laterality and severity of stenosis, cerebral
Computer Tomography results, and ischemic heart diseases
were measured preoperatively. The sample included
31 patients with dementia and 43 patients without any
symptom of dementia. Cognitive function was measured
again at 3 months postoperatively using a brief standardised
test.
After controlling for cognitive function and depression at
baseline, cognitive function improved significantly at 3 months
after CEA in both patients with and without dementia.
CEA may offer more than reduced stroke risk to patients,
independent of cognitive function
Is Tone at the Top Associated with Financial Reporting Aggressiveness?
No full textThe discussion about the relationship between tone at the top and financial reporting practices has been primarily focused on the oversight role played by the board of directors and other structural elements of corporate governance. Another relevant determinant of tone at the top is the corporate narrative language, since it is a fundamental way in which the chief executive officer (CEO) enacts leadership. In this study, we empirically explore the association between financial reporting aggressiveness and five thematic indicators capturing different traits of ethical leadership from 535 annual letters to shareholders. We find that aggressive financial reporting is positively associated with CEO letters using a language which is resolute, complex, and not engaging. Our empirical findings highlight the importance of examining discretionary corporate narratives for the auditing process and the role of tone at the top in influencing accounting practices
Counselling about the Risk of Preterm Delivery: A Systematic Review
No full textWe aimed to describe the outcomes of counselling for preterm delivery. PubMed, Embase, and PsycInfo were systematically searched (from 2000 to 2016) using the following terms: counselling, pregnancy complications, high-risk pregnancy, fetal diseases, and prenatal care. A total of nine quantitative studies were identified, five randomized and four nonrandomized. All studies were conducted in the USA, and half of them were based on a simulated counselling session. Two main clinical implications can be drawn from the available studies: firstly, providing written information before or during the consultation seems to have a positive effect, while no effect was detected when written material was provided after the consultation. Secondly, parents’ choices about treatment seemed to be influenced by spiritual-related aspects and/or preexisting preferences, rather than by the level of detail or by the order with which information was provided. Therefore, the exploration of parents’ beliefs is crucial to reduce the risks of misconception and to guarantee choice in line with personal values. More research is necessary to validate these findings in cross-cultural contexts and in real world settings of care. Moreover, the centeredness of conversations and the characteristics of the clinician involved in counselling should be addressed in future studies.</jats:p
Is the Optimism in CEO’s Letters to Shareholders Sincere? Impression Management Versus Communicative Action During the Economic Crisis
No full textIn this study, we explore the sincerity of the rhetorical tone of 664 annual letters to shareholders (CEO letters). Prior studies adopt Impression Management theory to predict that firms obfuscate failures and emphasize successes to unfairly enhance their image and maintain organizational legitimacy. Yuthas et al. (J Bus Ethics 41:141–157, 2002) challenged such a view, showing that firms reporting earnings surprises engage in ethical discourse with shareholders. We adopt the methodology of Yuthas et al. (J Bus Ethics 41:141–157, 2002) to explore the association between firm performance and the rhetorical features of CEO letters in a large sample of Fortune 500 firms in the wake of the global economic crisis. In contrast to most prior research, we find that optimistic tone is congruent with both past and future performance. We conclude that under tough macroeconomic conditions, incentives to distort public information strategically are low. Rather, firms tend to engage in communicative action aimed at dialoguing with shareholders through sincere disclosure. However, in our conclusions, we warn about the impact of accounting and rhetorical manipulation on the congruence between optimistic tone and financial performance
