The perception of languages by Italian native speakers
This essay showcases the results of a survey conducted on a sample of Italian speakers which focused on their perception of languages. The research, carried out in the second half of 2019, has enabled corroborating the initial hypothesis about the existence of preconceptions and stereotypes associated with the perception of foreign languages and cultures (Elman & McClelland 1986) by Italian people. In particular, a questionnaire was used to clarify which adjectives are commonly associated with selected foreign languages, in order to identify certain trends and stereotypes. The survey is based on ethnolinguistic and language education studies (Cardona 2006), and was performed through data collection techniques used in ethnography and sociolinguistics (Tagliamonte 2006)

L'aggiornamento dei docenti di italiano L2. Una ricerca sulle necessit\ue0 formative degli insegnanti
In this essay, we discuss the results of a questionnaire to observe the perception of
the needs associated with the professional training of Italian as Second Language teachers.
Previously, we investigated these necessities according to a scientific literature review. A
questionnaire was administered to a sample of teachers in order to explore the professional
needs and the critical aspects of Italian as Second Language Teaching. From data analysis
two significant needs emerge. The first being the formal instruction of language training, and
the second being to improve the communication between academic research and
professional life
Professional Training and Updating of Italian as Second Language Teachers. A Research on Teachers' Training Needs
In questo contributo sono discussi i risultati di un questionario relativo alle necessità formative del personale docente, che si occupa di insegnamento dell’italiano L2. A partire dalla valutazione della letteratura scientifica di riferimento, è stato strutturato un questionario per rilevare i bisogni formativi e gli aspetti critici in merito alla dimensione della didattica dell’italiano L2. Dall’analisi dei dati emerge con chiarezza il desiderio di formazione di carattere linguistico e la necessità di ulteriori raccordi fra mondo accademico e professionale.In this essay, we discuss the results of a questionnaire to observe the perception of the needs associated with the professional training of Italian as Second Language teachers.Previously, we investigated these necessities according to a scientific literature review.

Biosafety in surgical pathology in the era of SARS-Cov2 pandemia. A statement of the Italian Society of Surgical Pathology and Cytology
Surgical pathology units face chemical and biological risks. While chemical risks have been intensely evaluated since the formalin ban, less attention has been drown to biological risks. The actual epidemiologic situation due to the SARS-CoV-2 pandemia has raised a series of questions, which need to be addressed as soon as possible. We have to pursue two lines of action: on one hand we must immediately adopt urgent measures to reduce the risk of SARS-CoV-2 infection of laboratory personnel, and on the other hand, we must address crucial technical and organizational aspects of biological risk reduction, preserving as much as possible the quality of tissue and cell samples.
The evaluation of biological risk is an analytical process which involves different steps: a) characterization of the hazard (also known as risk assessment) and b) definition of a risk reduction strategy (also known as risk mitigation) 1.
Risk assessment implies a) the identification of the intrinsic biologic characteristics of the infectious agent, and b) the identification of the laboratory procedures related to the agent.
The intrinsic biologic characteristics of infectious agents are classified in 4 risk groups (RG) by the laboratory biosafety manual of the WHO 2. The RG range from level 1 (RG1) which includes microorganisms that are unlikely to cause human or animal disease, to level 4 (RG4) which includes pathogens which cause serious diseases, that can be readily transmitted from one individual to another, and for which effective treatment and preventive measures are not usually available.
Risk mitigation includes the definition of the appropriate a) level of biosafety of the laboratory, b) type of personal protection equipment (PPE), c) type of infrastructure and equipment, and d) education of involved personnel.
Laboratory biosafety is graded in 4 levels (BSL-1 to BSL-4) as exhaustively described in the laboratory biosafety manual of the WHO 2, and these levels are usually also defined by law (in Italy by the D. Lgs. 81/2008). BSL are a series of protections, which include individual safeguards designed to protect laboratory personnel, as well as the surrounding environment and community. The biosafety level required in laboratories derives from the characterization of the risk, and is not automatically derived from the risk group to which the pathogenic agent belongs. It is obvious that the biosafety level for a laboratory which cultivates a RG3 agent, will be higher than the level needed for a laboratory which performs diagnostic tests on inactivated biomaterials on the same agent.
Specific checklists, derived from the WHO laboratory biosafety manual, which in Italy are also defined by the National Institute of Labor Safety Insurance (Istituto Nazionale Assicurazione Infortuni sul Lavoro) in its 6th Fascicle published in 2010 3 are necessary to verify the compliance of a given laboratory with the required biosafety level
Caloric restriction counteracts age-dependent changes in prolyl-4-hydroxylase domain (PHD) 3 expression
Caloric restriction remains the most reproducible measure known to extend life span or diminish age-associated changes. Previously, we have described an elevated expression of the prolyl-4-hydroxylase domain (PHD) 3 with increasing age in mouse and human heart. PHDs modulate the cellular response towards hypoxia by regulating the stability of the α-subunit of the transcriptional activator hypoxia inducible factor (HIF). In the present study we demonstrate that elevated PHD3, but not PHD1 or PHD2, expression is not restricted to the heart but does also occur in rat skeletal muscle and liver. Elevated expression of PHD3 is counteracted by a decrease in caloric intake (40% caloric restriction applied for 6 months) in all three tissues. Age-associated changes in PHD3 expression inversely correlated with the expression of the HIF-target gene macrophage migration inhibitory factor (MIF), which has been previously described to be involved in cellular HIF-mediated anti-ageing effects. These data give insight into the molecular consequences of caloric restriction, which influences hypoxia-mediated gene expression via PHD3
