(Mis)informed? Identified skeletal collections, occupation, age at death and the reconstruction of physical activity
No full textIntroduction:
This paper expands on recent research by Milella et al. (2015) on the classification of documented occupations in the studies of entheseal changes (EC) addressing the following questions: can EC variability be used as classification criterion of occupations and, by proxy, assess physical activity? Which analytical protocols are more suitable when trying to control for the effect of age?
Materials and Methods:
Both bivariate (linear regression - LR) and multivariate (nonlinear principal component analysis – NLP and hierarchical cluster analysis - HCA) statistical protocols were used on a dataset (n=372, male individuals, 20-88 y.o.) of postcranial entheses from three contemporary Italian and Portuguese identified skeletal collections (ISC). The study focused on entheseal robusticity (ER) (i.e. relative surface roughness), on laterality separately and together, and on levels of asymmetry. Variance in robusticity was calculated after NLP for each occupation. Age-at-death was controlled using the residuals obtained after regressing each dimension obtained from NLPC with age and exploring possible groupings of occupation by means of HCA.
Results:
Robusticity variance showed a complex picture characterized by an overall separation between “high variable” and “low variable” occupations, which in some cases is consistent with specific exposures to distinct biomechanical patterns. Clusters of occupations based on residuals revealed a subdivision in three main classes as observed in Milella et al. (2015). The occurrence of problematic associations traces a more complex picture in which inherent sample biases, incomplete documentation and poor reliability of the EC investigated may have played their part.
Discussion and Conclusions:
Our results demonstrate that: (1) variability of ER is an interesting approach when studying subdivisions of documented occupation; (2) regression residuals are useful for controlling the effect of age on ER; and (3) the correlation between EC and specific behavioural patterns may be problematic (i.e. lack of homogeneity and documentation characterizing ISC)

Performance monitoring of the GE1/1 Triple-GEM detectors for the CMS Muon System
No full textThe muon system of the CMS experiment has been instrumented with a new station of triple-GEM detectors in order to ensure redundancy in the pseudo-rapidity region 1.552.18, keeping the trigger rate at an acceptable level while not compromising the CMS physics potential in Run 3 of the LHC. The station, named GE1/1, provides two additional muon track hit measurements which will improve the muon tracking and triggering performance in combination with the existing CSC detectors. As the commissioning phase of the detector is ongoing, prompt assessment of the muon detection performance is crucial for adjusting the operating parameters of the detector and its electronics. This contribution will present a set of analysis tools developed for the detector performance monitoring based on tools common to all the CMS muon subdetectors. Validation of the analysis based on simulations will be discussed, together with preliminary results obtained from cosmic-ray events
L’orientamento come dispositivo di prevenzione del disagio e della dispersione scolastica. Sfide pedagogiche e linee guida a confronto
No full textRipensare l’orientamento come dispositivo di prevenzione del disagio e della dispersione scolastica vuol dire riconoscerne il valore educativo, formativo, pedagogico e creare le condizioni affinché sia possibile lavorare
sul potenziale umano in rapporto al contesto di riferimento. Il presente contribuito descrive i risultati di uno studio esplorativo condotto per analizzare il fenomeno del disagio scolastico negli adolescenti del
territorio barese. Alla luce delle nuove Linee guida per l’orientamento presentate dal Ministero dell’Istruzione e del Merito, il contributo tratteggia alcune piste di riflessione sull’orientamento scolastico come possibile strumento di conoscenza e rafforzamento dell’identità personale, attraverso l’insegnamento delle character skills a scuola.Rethinking guidance as a tool to prevent discomfort and early school leaving means recognizing its educational, formative and pedagogical value and creating the conditions for working on human potential in relation to the reference context. This paper describes the results of an exploratory study conducted to analyze the phenomenon of school discomfort in adolescents in the city of Bari. In the light of the new Guidelines for Guidance presented by the Ministry of Education and Merit, the contribution outlines some paths of reflection on school orientation as a possible tool for knowledge and strengthening personal identity, through teaching character skills at school
