- Abstract
The paper focuses on the geomorphological processes and potential geo-hazards affecting the cultural heritage rock-cut sites of AlUla region. Its best-known site is Hegra, with more than 110 monumental tombs with elaborated façades carved directly into the sandstone rock. In addition, AlUla hosts a number of fascinating historical and archaeological sites such as its Old Town, surrounded by an ancient oasis, and Dadan, the capital of the Dadan and Lihyan kingdoms. The study is mainly aimed at investigating the local rock material, evaluating characteristics of rock masses, understanding rock degradation processes and characterizing the potential impact of slope instabilities on the conservation of cultural heritage.

- Abstract
The risk management of rainfall-induced landslides requires reliable rainfall thresholds to issue early warning alerts. The practical application of these thresholds often leads to misclassifications, either false negative or false positive, which induce costs for the society. Since missed-alarm (false negative) and false-alarm (false positive) cost may be significantly different, it is necessary to find an optimal threshold that accounts for and minimises such costs, tuning the false-alarm and missed-alarm rates. In this paper, we propose a new methodology to develop cost-sensitive rainfall thresholds, and we also analyse several factors that produce uncertainty, such as the accuracy of rainfall intensity values at landslide location, the time of occurrence, the minimum rainfall amount to define the non-triggering event, and the variability of cost scenarios. Starting from a detailed mapping of landslides that occurred during five large-scale rainfall events in the Italian Central Alps, we first developed rainfall threshold curves with a ROC-based approach by using both rain gauge and bias-adjusted weather radar data. Then, based on a reference cost scenario in which we quantified several cost items for both missed alarms and false alarms, we developed cost-sensitive rainfall threshold curves by using cost-curve approach (Drummond and Holte 2000). Finally, we studied the sensitivity of cost items. The study confirms how important is the information regarding rainfall intensity at the landslide site for the development of rainfall thresholds. Although the use of bias-corrected radar strongly improves these values, a large uncertainty related to the exact time of landslide occurrence still remains, negatively affecting the analysis. Accounting for the different missed-alarm and false-alarm misclassification costs is important because different combinations of these costs make an increase or decrease of the rainfall thresholds convenient.

SECS-P/07 - ECONOMIA AZIENDALE ,SDG, Agenda 2030, empirical evidence, information quality, accountability - Abstract
The document represents the first result of the study conducted by the research group "SDGs and business reporting" and aims to be the starting point of a process for corporate awareness towards sustainable development objectives. The document reveals our country commitment on Agenda 2030; a commitment that involves the entire "Italian system" in pursuit of the 17 sustainable development goals, through the active role of Italian companies as operators. Hence, it not only creates economic value on sustainable development but also it sensitize other companies, end users and the community in general. Although the results depict a sustainable development goals reporting in becoming and not entirely conscious, they provide inputs for entrepreneurs, directors, managers, regulators, consultants, etc. who, for various reasons, are the actors in a process of profound business change that is affecting the corporate reporting and disclosures. The document provides, in this context, useful hints to a better understanding the new corporate reporting direction; indeed, reporting is increasingly affected by an accountability process and responsibility towards both internal and external stakeholders.

LA RENDICONTAZIONE DI SOSTENIBILITÀ ,RENDICONTAZIONE SOCIALE ,assurance ,GLOBAL REPORTING INITIATIVE GBS OSSERVATIORIO DIRETTIVA - Abstract
Il contributo presenta il GRI e le relative linee guida per la rendicontazione di sostenibilità; indica i potenziali benefici conseguibili grazie all’utilizzazione di tali linee guida; spiega i contenuti delle recenti linee guida G3.1. La Global Reporting Initiative è un’organizzazione fondata nel 1997 su iniziativa della ONG statunitense Coalisation for Environmentally Responsible Economies (CERES), in collaborazione con l’United Nations Environment Programme (UNEP). L’obiettivo delle linee guida prodotte dal GRI è quello di consentire e guidare le aziende nella realizzazione dei report di sostenibilità, incrementando e migliorando la qualità dell’informazione prodotta, il rigore con il quale questa viene elaborata e l’utilità stessa dei report, intendendo questi ultimi come rendicontazione triple bottom line economico-sociale e ambientale. Uno dei principali punti di forza, e del conseguente vastissimo utilizzo delle linee guida GRI, risiede nel coinvolgimento degli stakeholder già durante l’impostazione del framework, coinvolgimento che si esplicita tramite molteplici modalità. Il risultato è la delineazione di linee guida condivise a livello internazionale, capaci di esprimere le esigenze conoscitive rilevate necessarie non solo da chi direttamente ha lavorato nell’ambito dei working group per elaborare il framework o i supplementi di settore, ma da tutti gli stakeholder che a vario grado hanno contribuito alla delineazione finale dei documenti, tramite focus group di stakeholder rappresentativi, survey on line aperti a chi voglia lasciare il proprio feedback o esprimere le proprie attese e molte altre forme di partecipazione. Le linee guida G3.1 del 2011 rappresentano la versione più recente. Il GRI sostiene di porsi come guida per coloro che gestiscono le imprese e di fungere da «complemento» e non da alternativa nella gestione della sostenibilità, proponendosi come strumento che incorpora e integra anche altre iniziative, pur nel rispetto della sua missione e dei suoi principi di rendicontazione. Si presentano i potenziali benefici per le imprese che pongono in atto questo tipo di scelta. Questi benefici possono essere così riassunti: a) si rende più efficiente il management a livello globale; b) il dialogo continuo con gli stakeholder aiuta nell’affrontare l’attuale complessità strategica ed operativa della gestione; c) si facilita il raggiungimento di rapporti fiduciari con tutti gli interlocutori, inclusi gli investitori (attuali o potenziali); d) si aiuta ad integrare meglio le decisioni sulle diverse funzioni aziendali (finanza, marketing, ricerca e sviluppo, ecc.); e) si valutano meglio in anticipo i danni per l’impresa dovuti a condotte scorrette; f) migliora la valutazione del contributo sociale complessivo dell’impresa e «Questa misurazione è centrale per mantenere e rafforzare la ‘licenza di agire’», cioè per mantenere una sorta di legittimazione da parte della società civile; g) «I bilanci di sostenibilità possono ridurre la volatilità e l’incertezza nel valore delle azioni per imprese quotate, riducendo così il costo del capitale». Si esaminano in rapida sintesi anche i punti centrali del recente documento G3.1, che riprendono le precedenti versioni, ma che pongono un più marcato riferimento ad aspetti quali la governance. Si vuole sottolineare come il documento G3.1 sia transitorio, ma in questo vi siano presenti diverse novità rispetto al documento G3, essendovi nuovi indicatori, la richiesta di ulteriori informazioni rispetto a quelle richieste nelle versioni precedenti, o la revisione dei contenuti di alcuni principi e indicatori. Le linee guida si concludono con un insieme di suggerimenti su come articolare i report di sostenibilità, ad esempio come aggregare i dati, la struttura e la frequenza del report. In particolare però la parte finale fa anche riferimento all’assurance. Si osserva che per affrontare al meglio il problema essenziale della credibilità e della fiducia di tutti gli stakeholder il GRI fornisce alcune indicazioni di metodo e di prassi, tra cui la dichiarazione del management con cui si attesta che si sta seguendo il GRI attenendosi al livello definito in accordance.

- Abstract
The non-profit sector in Italy is very articulate: associations, foundations, social enterprises, cooperatives, nongovernmental organizations operate to meet needs that the public administration is not able to cover. The organisations types are very different in terms of governance, organization, activity, financing models, mission and stakeholder reference. In this context, the first experiences of reporting, both financial, social and environmental were very different. Many organizations as part of a single network took step to adopt guidelines to encourage greater accountability of those realities, through the possibility of comparisons. The same accounting organizations have intervened, proposing guidelines for the preparation of documents and their control. The issue of standardization of the social and environmental reporting had been considered by the profit sector, where international organizations (GRI) and national (GBS) have proceeded to outline guidelines to facilitate comparison and analysis between different realities. The increasing importance of non-profit sector in Italy suggested the introduction of new rules and accounting principles, in order to require not only Financial Statements, but also “Sustainability Reports” for some sectors of non-profit organizations. It’s very important to inform about mission’s realization, whenever the social dimension of the mission is more important than the economic one.

- Abstract
Gli studi comparativi in ambito di accounting possono essere ricondotti ad un ambito di ricerca relativamente recente, che ha conosciuto uno sviluppo rilevante in conseguenza dell’adozione dei principi contabili internazionali IAS/IFRS. La ragioneria e l’economia aziendale e, in particolare, le prime forme di rilevazione contabile vengono considerate di origine italiana: tale riconoscimento è avvalorato dalla copiosa presenza di materiale contabile conservato negli archivi italiani, sia pubblici che privati, di gran lunga superiore rispetto alla situazione degli altri paesi in Europa e nel resto del mondo. I Maestri della Ragioneria che si sono occupati di studi storici hanno infatti evidenziato la superiorità della dottrina contabile italiana rispetto a quella dei paesi stranieri, fin dalle origini. Una prima inversione di tendenza in ambito di financial accounting inizia a manifestarsi dagli inizi del ‘900, in particolare per quanto riguarda gli studi provenienti dagli USA. Tale interesse si è poi intensificato con l’avvento della management accounting e in generale con gli studi riguardanti la pianificazione e il controllo di gestione. Uno degli studiosi che ha maggiormente sentito tale esigenza è stato Antonio Amaduzzi, in onore del quale è dedicato il presente lavoro. L'obiettivo della ricerca è volto ad indagare i primi studi a carattere comparativo fra la dottrina contabile italiana e quella statunitense, in particolare riguardo alla nozione di reddito e alla struttura del Conto Economico (CE) nel periodo storico post-zappiano. Le domande di ricerca sono le seguenti: 1. Quali erano le peculiarità del sistema contabile adottato negli USA nel Novecento? 2. Quali erano le principali differenze fra la dottrina classica italiana e l’impostazione dell’accounting statunitense? 3. Qual era l’atteggiamento degli studiosi italiani, e in particolare di Antonio Amaduzzi, nei confronti della financial accounting americana nel periodo post-zappiano? 4. In particolar

Background The aim of this study was to investigate the impact of computed tomography on the reliability of Boileau classification for proximal humerus fracture sequelae. Methods A prospective study was designed using STARD guidelines. We included all patients diagnosed with proximal humerus fracture sequelae who underwent surgery at our institution between 2017 and 2021. Preoperative radiographs and computed tomography scans were reviewed by three independent observers. Intra- and inter-observer reliability and the diagnostic accuracy of radiographs and computed tomography scans in detecting chronic dislocation, nonunion, and severe greater tuberosity dislocation were assessed. Results Fifty-two patients were included in the study. The overall interobserver agreement was low on both radiographs and computed tomography scans. On radiographic images, we found a sensitivity of 97%, 88.9%, and 84.1%, and a specificity of 58.3%, 40%, and 53.3% to detect chronic dislocation, nonunion, and greater tuberosity dislocation, respectively. On computed tomography scans we reported a sensitivity of 100%, 96.8%, and 93.7%, and a specificity of 91.7%, 86.7%, and 93.3% to detect chronic dislocation, nonunion, and greater tuberosity dislocation, respectively. Discussion Computed tomography scan was more specific than radiographs in the assessment of proximal humerus fracture sequelae. However, even using a three-dimensional evaluation of the deformity, the Boileau classification had a poor interobserver reliability. Level of Evidence I. Testing previously developed diagnostic criteria in a consecutive series of patients and a universally applied “gold standard.”

Accounting for the different missed-alarm and false-alarm misclassification costs is important because different combinations of these costs make an increase or decrease of the rainfall thresholds convenient. In our reference cost scenario, the most convenient threshold is lower than ROC-based thresholds because it seeks to minimise the number of missed alarms, whereas the missed-alarm costs are almost seven times greater than false-alarm costs. However, for different cost scenarios, threshold may vary significantly, as much as half an order of magnitude.

Purpose: Bi-parametric prostate MR (bp-MR) is a valuable tool for detection and characterization of prostate cancer (PCa). Recent studies suggested that PSA-density (PSA-D) in combination with multi-parametric prostate MR as well as bp-MR may achieve a higher diagnostic accuracy than either alone. We aimed to evaluate the diagnostic performance of bp-MR, PSA-D and their combination in biopsy-naïve patients. Methods and materials: We retrospectively analyzed 334 consecutive patients who underwent prostate MR on a 3T scanner. Only patients (n = 114) who underwent TRUS-biopsy within 30 days following MR with no previous prostate biopsies were considered. Our protocol included T2-weighted and DWI sequences. A Likert score based on PI-RADS v2 was used for bp-MR evaluation. Lesions were graded histopathologically using the ISUP score. We assessed three scenarios: detection of lesions independently of ISUP score (ISUP ≥ 1), detection of both intermediate and clinically significant lesions (ISUP ≥ 2) and detection of clinically significant lesions alone (ISUP ≥ 3). Predictive value of bp-MR and PSA-D was evaluated by ROC curves and logistic regression analysis. A p value < 0.05 was considered statistically significant. Results: In all evaluated scenarios, bp-MR showed a significantly higher predictive power (AUC = 0.87-0.95) compared to the performance of PSA-D (AUC = 0.73–0.79), while their combination (AUC = 0.91-0.95) showed no statistically significant improvement compared to bp-MR alone. Conclusion: Our results confirm that bp-MR is a powerful tool in detection of clinically significant PCa. Contrary to findings in the recent literature, PSA-D does not appear to significantly improve its diagnostic performance.

Objectives To prospectively determine the diagnostic accuracy of a biparametric 3T magnetic resonance imaging protocol (BP-MRI) for prostatic cancer detection, compared to a multiparametric MRI protocol (MP-MRI), in a biopsy naive patient population. Methods Eighty-two untreated patients (mean age 65 ± 7.6 years) with clinical suspicion of prostate cancer and/or altered prostate-specific antigen (PSA) levels underwent a MP-MRI, including T2-weighted imaging, diffusion-weighted imaging (with the correspondent apparent diffusion coefficient maps) and dynamic contrast enhanced sequence, followed by prostate biopsy. Two radiologists reviewed both the BP-MRI and the MP-MRI protocols to establish a radiological diagnosis. Receiver operating characteristics curves were obtained to determine the diagnostic performance of the two protocols. Results The mean PSA level was 8.8 ± 8.1 ng/ml. A total of 34 prostatic tumors were identified, with a Gleason score that ranged from 3 + 3 to 5 + 4. Of these 34 tumors, 29 were located within the peripheral zone and 5 in the transitional zone. BP-MRI and MP-MRI showed a similar performance in terms of overall diagnostic accuracy, with an area under the curve of 0.91 and 0.93, respectively (p = n.s.). Conclusions BP-MRI prostate protocol is feasible for prostatic cancer detection compared to a standard MP-MRI protocol, requiring a shorter acquisition and interpretation time, with comparable diagnostic accuracy to the conventional protocol, without the administration of gadolinium-based contrast agent.

Introduction To evaluate if advanced neuroimaging research is mainly conducted by imaging specialists, we investigated the number of first authorships by radiologists and nonradiologist scientists in articles published in the field of advanced neuroimaging in the past 10 years. Methods Articles in the field of advanced neuroimaging identified in this retrospective bibliometric analysis were divided in four groups, depending on the imaging technique used. For all included studies, educational background of the first authors was recorded (based on available online curriculum vitae) and classified in subgroups, depending on their specialty. Finally, journal impact factors were recorded and comparatively assessed among subgroups as a metric of research quality. Results A total number of 3831 articles were included in the study. Radiologists accounted as first authors for only 12.8 % of these publications, while 56.9 % of first authors were researchers without a medical degree. Mean impact factor (IF) of journals with non-MD researchers as first authors was significantly higher than the MD subgroup (p < 10−20), while mean IF of journals with radiologists as first authors was significantly lower than articles authored by other MD specialists (p < 10−11). Conclusions The majority of the studies in the field of advanced neuroimaging in the last decade is conducted by professional figures other than radiologists, who account for lessthan the 13 % of the publications. Furthermore, the mean IF value of radiologists-authored articles was the lowest among all subgroups. These results, taken together, should question the radiology community about its future role in the development of advanced neuroimaging.

SECS-P/07 - ECONOMIA AZIENDALE ,Sustainability, Non-Profit, Report - Abstract
The non-profit sector in Italy is very articulate: associations, foundations, social enterprises, cooperatives, nongovernmental organizations operate to meet needs that the public administration is not able to cover. The organisations types are very different in terms of governance, organization, activity, financing models, mission and stakeholder reference. In this context, the first experiences of reporting, both financial, social and environmental were very different. Many organizations as part of a single network took step to adopt guidelines to encourage greater accountability of those realities, through the possibility of comparisons. The same accounting organizations have intervened, proposing guidelines for the preparation of documents and their control. The issue of standardization of the social and environmental reporting had been considered by the profit sector, where international organizations (GRI) and national (GBS) have proceeded to outline guidelines to facilitate comparison and analysis between different realities. The increasing importance of non-profit sector in Italy suggested the introduction of new rules and accounting principles, in order to require not only Financial Statements, but also “Sustainability Reports” for some sectors of non-profit organizations. It’s very important to inform about mission’s realization, whenever the social dimension of the mission is more important than the economic one.

Gli studi comparativi in ambito di accounting possono essere ricondotti ad un ambito di ricerca relativamente recente, che ha conosciuto uno sviluppo rilevante in conseguenza dell’adozione dei principi contabili internazionali IAS/IFRS. La ragioneria e l’economia aziendale e, in particolare, le prime forme di rilevazione contabile vengono considerate di origine italiana: tale riconoscimento è avvalorato dalla copiosa presenza di materiale contabile conservato negli archivi italiani, sia pubblici che privati, di gran lunga superiore rispetto alla situazione degli altri paesi in Europa e nel resto del mondo. I Maestri della Ragioneria che si sono occupati di studi storici hanno infatti evidenziato la superiorità della dottrina contabile italiana rispetto a quella dei paesi stranieri, fin dalle origini. Una prima inversione di tendenza in ambito di financial accounting inizia a manifestarsi dagli inizi del ‘900, in particolare per quanto riguarda gli studi provenienti dagli USA. Tale interesse si è poi intensificato con l’avvento della management accounting e in generale con gli studi riguardanti la pianificazione e il controllo di gestione. Uno degli studiosi che ha maggiormente sentito tale esigenza è stato Antonio Amaduzzi, in onore del quale è dedicato il presente lavoro. L'obiettivo della ricerca è volto ad indagare i primi studi a carattere comparativo fra la dottrina contabile italiana e quella statunitense, in particolare riguardo alla nozione di reddito e alla struttura del Conto Economico (CE) nel periodo storico post-zappiano. Le domande di ricerca sono le seguenti: 1. Quali erano le peculiarità del sistema contabile adottato negli USA nel Novecento? 2. Quali erano le principali differenze fra la dottrina classica italiana e l’impostazione dell’accounting statunitense? 3. Qual era l’atteggiamento degli studiosi italiani, e in particolare di Antonio Amaduzzi, nei confronti della financial accounting americana nel periodo post-zappiano? 4. In particolare, data la grande influenza esercitata in Italia dalla scuola zappiana, quale era la nozione di reddito e la struttura del conto economico?

Responsabilità Sociale, Azienda, economia di comunione, accountability - Abstract
Per tracciare i nuovi orizzonti dell’ accountability nelle aziende dell’Economia di Comunione(EdC) occorre volgere lo sguardo al passato ed evidenziare L’evoluzione effettuata, sia dal punto di vista teorico, sia dal punto di vista empirico, in merito a questo argomento. Tale evoluzione deve tenere conto delle specificità e delle novità proposte da queste aziende collegando l’accountability stessa alle modalità di definizione della mission ed alle modalità di definizione della corporate governance a cui è legata e di cui non trattiamo esplicitamente in questa sede. La ricerca su questo argomento è iniziata circa tre anni or sono, attraverso l’acquisizione di informazioni su tali aziende, basata sulla lettura, sia dei casi aziendali, che sono stati presentati ai numerosi convegni di presentazione del progetto, sia anche attraverso i numerosi colloqui con i proprietari delle aziende, che fanno parte di questo progetto. Dalla lettura di alcuni casi italiani è emersa la curiosità di approfondire la conoscenza di tali aziende e ciò è stato effettuato attraverso la somministrazione di questionari diretti ai responsabili amministrativi di tali aziende, questionari necessari per conoscere i caratteri della loro mission , governance ed accountability

- Abstract
Background : As adipose tissue-derived mesenchymal stem cells are becoming the tool of choice for many clinical applications; standardized cryopreservation protocols are necessary to deliver high-quality samples. For this purpose, the cryopreservation and thawing of native adipose tissue under GMP conditions could represent an extremely useful and powerful tool for the direct reinfusion of the tissue, and consequently, of its stromal vascular fraction. Methods : In this study, 19 samples of adipose tissue were cryopreserved and characterized before and after storage in liquid nitrogen vapors. Of these 19 samples, 14 were processed in research and 5 in a GMP-compliant environment. Storage with and without cryopreservation medium was also evaluated. After one week to three months of storage, samples were thawed, washed, enzymatically digested, and characterized with flow cytometry. Results : The results show that there is a loss of nearly 50% of total nucleated cells during the cryopreservation/thawing process. Non-GMP and GMP samples are comparable for all parameters analyzed. This study also allowed us to exclude the cryopreservation of adipose tissue without any cryopreservation medium. Conclusions : The data shown in this work are consistent with the idea that native adipose tissue, if properly processed and controlled, could be a useful source of cells for regenerative medicine, keeping in mind that there is a clear difference in the quality between fresh and thawed samples.

- Abstract
Groin pain syndrome (GPS) is one of the most frequent injuries in competitive sports. Stresses generated in the lower limbs by quick turns and accelerations, such as in soccer, basketball or hockey, can produce localized regions of increased forces, resulting in anatomical lesions. The differential diagnoses are numerous and comprise articular, extra-articular, muscular, tendinous and visceral clinical conditions and a correct diagnosis is crucial if treatment is to be efficient. MRI is the gold standard of diagnostic techniques, especially when an alternative pathology needs to be excluded and/or other imaging techniques such as ultrasound or radiography do not lead to a diagnosis. This paper, based on the current literature, gives a comprehensive review of the anatomy of the pubic region and of the typical MRI findings in those affected by GPS. Many clinical conditions causing GPS can be investigated by MRI within appropriate protocols. However, MRI shows limits in reliability in the investigation of inguinal and femoral hernias and therefore is not the imaging technique of choice for studying these clinical conditions.
