No full textIl saggio intende ricostruire, avvalendosi tanto dei dati architettonici sopravvissuti quanto delle fonti di archivio, quale sia stato il tributo evergetico dell'arcivescovo e monaco cistercense Luca Campano nella riformulazione della cattedrale di Cosenza, consacrata agli inizi del 1222 al cospetto di Federico II di Svevia in veste di Re di Sicilia
Capabilities and sustainable competitive advantage: a three papers based, multi-methods investigation
No full textA CNN-ViT hybrid architecture search benchmark on a large-scale dataset
No full textIn recent years, Neural Architecture Search (NAS) has emerged as a promising methodology to automate the design of deep neural networks, enabling the discovery of high-performing architectures across a wide range of tasks. Due to the high computational cost associated with NAS, several benchmarks have been introduced to support the development and evaluation of NAS methods. However, existing benchmarks are often limited in scope, typically relying on small-scale datasets or narrow search spaces, mostly based on Convolutional Neural Networks (CNNs) only. To address these limitations we introduce HyViTas-Bench, a novel NAS benchmark specifically tailored for hybrid CNN-Vision Transformer (ViT) architectures. HyViTas-Bench contains 6,561 unique models trained three times on a reduced, yet large scale, version of ImageNet-1k, offering an evaluation setting that better reflects realistic data. Each architecture is evaluated on 19 hardware platforms (CPU, GPU, and edge devices) for latency measurements, while robustness is validated through repeated training. We also provide an analysis of Out-of-Distribution (OoD) generalization using three external datasets. HyViTas-Bench enables a multifaceted assessment of NAS methods in terms of accuracy, latency, generalization capability, and model size. As such, it represents a valuable resource for advancing research on hybrid architectures and for facilitating the design and comparison of NAS strategies under more realistic and diverse evaluation criteria
Paradoxical Execution for New Ventures’ Scalability: Evidence from Y Combinator
No full textAccelerators have emerged as important organizational sponsors capable of hastening new ventures’ development by helping founders acquire entrepreneurial capabilities. Research has provided evidence that accelerated ventures, on average, develop more rapidly, attract more capital, have more employees, and receive higher evaluations. Yet, we know little about how accelerators foster new ventures’ scalability. To develop theoretical insights that might help fill this gap, we conduct an inductive case study of Y Combinator (YC), the first modern accelerator that specifically focuses on helping ventures achieve a large scale. Through a unique combination of 64 video interviews and 7,283 pages of archival material, we find that the strategic goals and methodological guidelines of YC’s acceleration program pressure founders to pursue conflicting priorities simultaneously, thus forming a pattern that we termed Paradoxical Execution. We reveal that those paradoxes must be addressed in a simultaneous rather than sequential way, and for this reason accelerators urge startups to develop a paradoxical mindset. Hence, we unveil how contrasts and paradoxes are likely to manifest from the very early stage of new ventures’ life cycle, contrariwise to what existing literature suggests. Altogether, our findings contribute to the literature on entrepreneurial ecosystems, paradox theory, and organizational scaling
A prospective case series on surgical treatment of circumferential and semi-circumferential defects due to peri-implantitis
No full textDifferent surgical treatment strategies for peri-implantitis with the use of graft material and membranes have been suggested without any longitudinal remarkable success rate. The present preliminary study was aimed to analyze a new clinical approach based on the disinfection of the implant connection, the disinfection of the implant surface and GBR approach in the treatment of circumferential and semi-circumferential bony defect resulting from peri-implantitis. Six consecutive patients were selected for the present study. After removal of factors that could potentially influence peri-implant pathology, the prosthetic rehabilitation was always removed and a full thickness flap was elevated to allow access to the peri-implant defect and the exposed implant surface. Once the defect was degranulated and the implant surface cleaned, a mixture (50:50) of autogenous bone and allograft was used. Guided bone regeneration technique using membranes was adopted and the flaps were closed for a submerged healing. Six months thereafter, a new re-opening procedure was performed and cleaned superstructures and crowns were repositioned. Patients were followed for one year thereafter and recalled for a customized oral hygiene every three months. Radiological and periodontal analysis was performed before surgery and every six months. The studied procedure was associated with a pronounced increase in REC and CAL with stable peri-implant conditions at 6 and 12 months. PI, BOP and PD values were significantly reduced both at 6 and 12 months. At 12 months, a mean PD gain of 4.5 mm and a bone loss reduction of 5.1 mm was obtained. Within the limitation of the present preliminary study, the proposed technique might represent a promising result for treatment of circumferential and semi-circumferential bone defects around implants affected by peri-implantitis
One more time trust matters: a theoretical investigation of the role of technology mediated trust in the UTAUT model
No full textInvestigation about technology acceptance (TA) remains one of the most important research field in information system literature, but the “founding father models” originated the notion of TA in a completely different scenario. We argue that, in a world where IT artifacts disseminate thanks to—and not only because of—unprecedented social media penetration, the TA models must be revisited and upgraded. In this paper, the construct of trust plays a central role, because it allows the acknowledgement of the influencing role played by institutions and organizations that have reached a credible and sustainable presence in the information technology market. We started from the TAM and UTAUT models, as departing platforms of TA models, being the mostly widely cited in the recent literature. This paper defines and explores the theoretical contribution of technology-mediated trust, as a new moderating factor adding value to the UTAUT model. Implications for future empirical research are finally presented

La cattedrale di Cosenza in retrospettiva: l'orma della fondazione normanna, con un'appendice di Lorenzo Mercuri
No full textIl contributo si pone come obiettivo quello di individuare il luogo urbano ove fu costruita sul finire dell'XI secolo la cattedrale normanna di Cosenza, così come di risalire alle forme del suo impianto basilicale che ha improntato la successiva ricostruzione proto-duecentesca della fabbrica arcivescovile consacrata al cospetto di Federico II di Svevia e di Luca Campano nell'inverno del 1222
From college to consulting through the main door: when IT skills make a difference for junior enterprise students
No full textFor many European college students, Junior Enterprise (JE) is a popular part of the educational process that is designed to give them real life exposure to companies. Many students aspire entering the consulting field, and the JE experience becomes a way to
signal their fit to potential employers. However, our analysis conducted on 768 different LinkedIn professional profiles shows stark differences between students who lack technical skills and those with strong technical skills. In particular, while higher IT skills
are, on average, positively correlated with the individual probability of becoming a consultant, this positive effect is significantly moderated by gender, undergraduate major and role played within JE. Using signaling theory to explain our results, we find
evidence that signals are not universal and, for some groups, high IT skills are more important than to other ones
Developing the Entrepreneurial Paradox Mindset: The Role of Startup Accelerators and Educational Programs
No full textStartup founders often encounter paradoxical tensions. Yet, whether and how startup accelerators can equip founders to embrace such contradictions remains underexplored. Our study of Y Combinator reveals that accelerators can play a pivotal role in cultivating an entrepreneurial paradox mindset by exposing founders to teachings about paradoxical tensions, imparting heuristics to navigate them, and implementing thoughtful design choices to foster learning—particularly through vicarious and experiential learning opportunities. This study integrates paradox theory into entrepreneurship research, contributes to understanding the interplay between accelerator design choices and entrepreneurial learning, extends knowledge of entrepreneurial mindsets, and provides several practical insights
