Transform to adapt or resilient by design? How organizations can foster resilience through business model transformation.
No full textAdvisors and consultants consider business model transformation (BMT) as vital in responding to disruptive events like the COVID-19 pandemic. However, some companies demonstrated exceptional resilience during the pandemic without BMT. Given this scenario, we investigate the effect of BMT on firm resilience in 2020, the pandemic’s first year. We collect data from 336 Italian companies and develop an improved resilience measure that maximizes consistency with our theoretical framework. The results reveal that firms following an adaptive path towards resilience successfully leverage BMT. We also found that innovative and more internationalized companies are more likely to follow an absorptive path towards resilience, thus reducing the need for BMT when facing shocks. High levels of resilience can be achieved through small adjustments around a situation of constant equilibrium. Our study advances the resilience literature by showing that an absorptive path is equally effective to an adaptive path in fostering organizational resilience

No full textThe scientific debate in English-speaking texts : between ESP and CDS
No full textThe aim of this paper is to provide first a brief outline of the developments undergone by ESP as a field of study in applied linguistics from its onset to the present day and, second, to hypothesise a possible direction it may follow in future years. It has tried to show the main points of contacts and hybridisation with other perspectives in linguistics, evidencing the beneficial results and the occasional issues of these encounters. Finally, it has reviewed a few select studies conducted by the author over the past decade along the methodological lines exposed, as an illustration of one possible evolutionary pattern in ESP studies. These investigations have focused on the medical and scientific domains, and especially on the representation of scientific debates raising bioethical concerns with social repercussions by institutions, popular sources and the media, and have employed various perspectives in applied linguistics, also combining them with methods in social sciences

Dysphagia in post-carotid endarterectomy: a prospective study
No full textDysphagia can be a debilitating complication in carotid endarterectomy. This study describes our experience in the management of this complication. We prospectively assembled an inception cohort of 19 consecutive, hospital-referred patients with dysphagia post-carotid endarterectomy. We performed swallowing evaluation in all the recruited patients both at the bedside and by fiberoptic endoscopic evaluation of swallowing (FEES) 5 days and 3 months after the operation, using standardized methods and diagnostic criteria. The degree of dysphagia was scored using the Penetration-Aspiration Scale (PAS). All patients were undergoing early rehabilitation treatment and were followed up prospectively for 3 months, during which time recovery of swallowing function and any occurrence of pneumonia were recorded. At baseline, 15 patients presented dysphagia for liquid and solid food and four for solid food only, eight were on parenteral nutrition, and six presented bronchial aspiration (by FEES). The mean PAS score at the first evaluation was 5.2. Ten patients completely recovered swallowing function and returned to their preoperative diet within 1 month, and six did so within 3 months; the other three patients did not complete the follow-up. No patient presented pneumonia. At the 3-month follow-up, one patient presented bronchial aspiration and the mean PAS score was 1.2. This preliminary experience suggests that careful evaluation of swallowing and early rehabilitation may be advisable in these patients

Abstract
AIM:
Aim of the study was to evaluate a single center experience on hybrid treatment for thoracic aortic diseases, including aortic arch and ascending aorta endografting needing a total debranching from descending thoracic aorta and an antegrade endograft deployment from left ventricle.
METHODS:
Between January 2004 and December 2010 48 patients underwent thoracic aorta endografting, with coverage of at least one supra-aortic artery, because of atherosclerotic, dissecting and post-traumatic aneurysms or complications of previous aortic surgery. Supra-aortic trunks revascularization was obtained from ascending aorta, common carotid arteries and, in three cases, from descending thoracic aorta since the unavailability of common inflow sites. In three cases the antegrade endograft introduction through left ventricle (transapical approach, 2 cases) or ascending aorta (one case) was the only possibility for a safe deployment.
RESULTS:
Three groups have been identified on the basis of the proximal landing zone. Group A (27 patients): zone 2; Group B (9 patients): zone 1; Group C (12 patients): zone 0. The 30 days mortality was respectively 7.4%, 0% and 16%. Post operative paraplegia occurred in the 7.4% of group A, respiratory insufficiency and infections were the main post-operative complications with an incidence reaching 30% in each group.
CONCLUSION:
Hybrid procedures on aortic arch represent a possible treatment for cases unfit for open surgery despite the complication rates and mortality are not negligible. In selected cases, the endografting can be extended up to beyond the landing zone 0 where an antegrade transventricular endograft deployment and a supra-aortic perfusion from descending thoracic aorta represent a feasible option
Disentangling the “digital”: A critical review of IT capabilities, IT-enabled capabilities, and digital capabilities in business research
No full textBusiness and management scholars have always placed a strong emphasis on the study of capabilities. As digital technology moves from the back office to the forefront of digital innovation and transformation, organizations increasingly recognize the vital role of their digital-related capabilities. Yet, despite the attention, substantial confusion remains in the cross-disciplinary management and business literature, caused by conflating related, yet distinct, constructs: IT capabilities, IT-enabled capabilities, and digital capabilities. Our objective in this article is twofold. First, we analyze the capability literature across business research areas to identify weaknesses, contradictions, controversies, or inconsistencies regarding “IT” and “digital” constructs. We do so by conducting a theory-driven critical review encompassing 360 papers in fields ranging from accounting to strategy. Second, our paper advances a theoretical framework that clarifies the differences across IT capabilities, IT-enabled capabilities, and digital capabilities. It also provides solid ground for future inquiry by ensuring reliable knowledge accumulation while pointing research attention to unique and novel research questions
Sea Caves and Other Landforms of the Coastal Scenery on Gozo Island (Malta): Inventory and New Data on Their Formation
No full textSea caves are a type of cave formed primarily by the wave action of the sea. The coastal scenery of the Gozitan coast is very interesting in that sea caves and other coastal landforms, such as sea arches, develop at the sea level. We mapped seventy-nine semi-submerged sea caves opening at the sea level, five completely submerged sea caves, seven sea arches, one sea stack, and one shelter around the coast of Gozo, mainly in the Western and Eastern parts of the island, due to favorable lithological and topographical conditions. Additionally, we surveyed the topography of the emerged part of nine sea caves using the iPhone build-in LiDAR sensor, and eight sea caves in the submerged part using SCUBA equipment. This inventory represents the most detailed example of a database of coastal caves and related forms in the Mediterranean, mainly sourced from a swimming survey along the entire island. Thanks to the combination of outputs of the above-water emerged and submerged surveys, we defined three types of semi-submerged sea caves: (i) box caves, (ii) joint caves, and (iii) complex caves. Moreover, we added a cave-like landform above the sea level on calcarenites called shelter, or a little extended notch deeply carved into the cliff. The shape mainly depends on the structural and lithological setting of sea cliffs. In the Western sector of the island, we also discovered the only sea cave in Gozo, measuring 122 m in length and 10 m in width, with its floor developing above the mean sea level. This cave base is of interest due to rounded landforms related to marine erosion. In the innermost part of the cave, there is also a beach with rounded pebble at an elevation of about 7 m asl. Considering the tectonic stability of the island, it could be possibly related to the MIS 5.5 highstand
