An organization design redefinition for the tourism sector using design thinking: Sustainable hotels case study

This chapter shows how the Classic Design Theory may be applied to create a new philosophy for organizations. In this study it is applied to a project in tourism sector. An investigation was made first in different companies in several sectors of activity in Portugal and has been recently successfully applied. The purpose of the chapter is to show how the identification and experimentation of concepts and methods used in classical design allow a better understanding of the implications they have in the engineering organization design theory. To renew the engineering organization design, an organizational design framework was conceived in order to use classical design methods and adapt them to organizational design theories. A contribution is made not just to the art of science of a designed-based organization design theory, but also to create and to test any organization design. Several alternative organization designs came out from the involved action research. We will present several examples of organization design interface based on real Eco Hotel. This represents a useful tool for organization design practitioners and non-organization design practitioners. For this purpose, an appliance was made and tested involving real organizations, interviews and focus groups (namely in the wine sector, or in the design sector, or yet on a NGO). The final result of this action research was a design-based organization design framework and its outcomes - which are unique, beautiful, functional, simple and sustainable – a design-based organization design interface that people love, considering always the context and user profile on which it is inserted.info:eu-repo/semantics/submittedVersio

A model to choose a management team for a tourism company

In Portugal, many tourism companies deal with a management problem regarding their low dimension and productivity. Therefore, an additional concern must be given to the management model, in order to increase their success. An innovating model is given for a situation in which a hotel aims to choose a management team according to a set of competences and skills to give the company the necessary ability to be competitive and to survive in a very competitive market. This paper aims at presenting, through game theory, a way to have the best choice that allows ordering the potential candidates that will constitute the co-leadership team. This requires a successful team with a renewed co-leadership model of co-leaders.info:eu-repo/semantics/acceptedVersio

A Cohort Analysis

Publisher Copyright: © 2022Background and Aims: The donor risk index (DRI) quantifies donor-related characteristics potentially associated with increased risk of early graft failure. We aimed to assess the impact of the DRI, recipient and perioperative factors on post liver transplant (LT) outcomes. Methods: This was a single-center retrospective cohort study including all adult (≥18 years) patients who underwent LT from 01/2019 to 12/2019 at Curry Cabral Hospital, Lisbon, Portugal. Primary endpoint was 1-year graft failure post LT. Associations were studied with logistic regression. Results: A total of 131 cadaveric donor LT procedures were performed in 116 recipients. Recipients' median (IQR) age was 57 (47-64) years and 101/131 (77.1%) were males. Cirrhosis was the underlying etiology in 95/131 (81.2%) transplants. Based on 8 predefined donors' characteristics, median (IQR) DRI was 1.96 (1.67-2.16). Following adjustment for MELDNa score pre LT and SOFA score (adjusted odds ratio [aOR], 95% confidence interval [CI] = 0.91 [0.56-1.47]) or lactate (aOR [95% CI] = 2.76 [0.71-10.7]) upon intensive care unit (ICU) admission post LT, DRI was not associated with 1-year graft failure. However, higher SOFA score (aOR [95% CI] = 1.20 [1.05-1.37]) or lactate (aOR [95% CI] = 1.27 [1.10-1.46]) upon ICU admission post LT were independently associated with higher odds of 1-year graft failure. Conclusions: In a recent cohort of patients who underwent LT, DRI, despite being high, was not associated with 1-year graft failure, but SOFA score or lactate upon ICU admission post LT were.publishersversionepub_ahead_of_prin

Predicting Function Delay with a Machine Learning Model: Improve the Long-term Survival of Pancreatic Grafts

The impact of delayed graft function on outcomes following various solid organ transplants is well documented and addressed in the literature. Delayed graft function following various solid organ transplants is associated with both short- and long-term graft survival issues. In a retrospective cohort study including 106 patients we evaluated whether pancreas graft survival differs according to moment of insulin therapy following simultaneous pancreaskidney transplant. As a result, we aimed to identify possible risk factors and build a machine-learning-based model that predicts the likelihood of dysfunction following SPK transplant patients based on day zero data after transplant, allowing to enhance pancreatic graft survival. Feature selection by Relief algorithm yielded donor features, age, cause of death, hemoglobin, gender, ventilation days, days in ICU, length of cardiac respiratory arrest and recipient features, gender, long-term insulin, dialysis type, time of diabetes mellitus, vPRA pre-Tx, number of HLA-A mismatches and PRDI, all contributed to the models' strength.info:eu-repo/semantics/publishedVersio
