Violence and unsafety in Italian hospitals: Experience and perceptions of nursing students.

BACKGROUND: Assessment of workplace violence towards healthcare workers represents a challenge for healthcare organizations worldwide. Workers' experience and perceived risk of violence may have a serious impact on job satisfaction and retention of workers. To date, no studies have been conducted on nursing students. OBJECTIVES: To assess the prevalence of physical and non-physical violence among nursing students during their clinical experiences and to analyze the perceived risk of violence. METHODS: Multicentre, cross-sectional survey. We enrolled a convenience sample of nursing students of the bachelor's degree in Nursing of the University of Milan (Italy). The students completed a structured questionnaire prepared in accordance with the available literature on violence in healthcare settings. RESULTS: Out of 1185 questionnaires sent, 603 were collected (50.89%). 35.1% had experience of verbal violence during the clinical internship training period, while 8.1% were victims of physical violence. 202 students (33.5%) reported unsafety, which was related to experience of physical or psychological violence, witnessed episodes of violence, gender, hospital structure and efficacy of the safety policies. CONCLUSIONS: Our findings highlight that nursing students are exposed to the risk of violence which influences their perception of risk.

Mechanical properties of Municipal Solid Waste by SDMT.

In the paper the results of a geotechnical investigation carried on Municipal Solid Waste (MSW) materials retrieved from the "Cozzo Vuturo" landfill in the Enna area (Sicily, Italy) are reported and analyzed. Mechanical properties were determined both by in situ and laboratory large-scale one dimensional compression tests. While among in situ tests, Dilatomer Marchetti Tests (DMT) is used widely in measuring soil properties, the adoption of the DMT for the measurements of MSW properties has not often been documented in literature. To validate its applicability for the estimation of MSW properties, a comparison between the seismic dilatometer (SDMT) results and the waste properties evaluated by laboratory tests was carried out. Parameters for "fresh" and "degraded waste" have been evaluated. These preliminary results seems to be promising as concerns the assessment of the friction angle of waste and the evaluation of the S-wave in terms of shear wave velocity. Further studies are certainly required to obtain more representative values of the elastic parameters according to the SDMT measurements.
