Mesh complications following prolapse surgery: management and outcome.
2011
Abstract Objective This is a description of complications following prolapse surgery with the use of alloplastic materials, the management and outcome. Study design 54 women have been referred to Mainz, urogynecology referral center due to complications following mesh-augmented prolapse surgery. Results The complaints who lead to the admission are expressed by the new terminology and standardized classification for complications arising directly from the insertion of prostheses and grafts in female pelvic floor surgery [1] . Pain (66.7%), mesh erosion (55.6%) and vaginal discharge (48.1%) were the most frequent complaints. Revision was performed after a median time of 27.2 months post mesh …
Validation procedures in radiological diagnostic models. Neural network and logistic regression
1999
The objective of this paper is to compare the performance of two predictive radiological models, logistic regression (LR) and neural network (NN), with five different resampling methods. One hundred and sixty-seven patients with proven calvarial lesions as the only known disease were enrolled. Clinical and CT data were used for LR and NN models. Both models were developed with cross validation, leave-one-out and three different bootstrap algorithms. The final results of each model were compared with error rate and the area under receiver operating characteristic curves (Az). The neural network obtained statistically higher Az than LR with cross validation. The remaining resampling validatio…
Introducing a strategic perspective in lean thinking applications through system dynamics modelling: the dynamic Value Stream Map
2020
PurposeLean Thinking is an operation management discipline which aims to identify, map and analyse the activities forming a process to detect “value waste” and outline the most effective flow of activities to execute in sequence. Process mapping is often developed in lean projects through the use of the Value Stream Map (VSM). Like many other management tools, the VSM adopts a static and non-systemic perspective in the representation of an organizational process. This may result in the implementation of Lean projects inconsistent with the overall organizational long-term strategy, thus leading to dysfunctional performance. In order to overcome this limit, the paper suggests combining VSM wi…
An active inference and epistemic value view of metacognition
2015
Metacognition concerns our monitoring and control of mental operations (knowing what you know). Much thinking about metacognition is liable to fall foul of the classic homunculus problem: Nobody can specify who or what does the "metacognition." We describe how the Active Inference and Epistemic Value (AIEV) model offers an operationalization of epistemic behaviors which can explain two example metacognitive phenomena: Control and monitoring of word learning, and the search for unretrieved information in the feeling of knowing. Curiosity drives a search forward, but it is held in check by considering the utility of what is retrieved from memory.
Racism and ethics in the globalized business world
2002
This paper analyzes the concept of racism in the context of business ethics and globalization. It first introduces three ethical traditions to understand moral issues in business: deontological, utilitarian and virtue ethics. Then it discusses about the challenges and demands that globalization has set to multicultural and multinational business operations. Third, it clarifies how racism works when it is understood as an ideology‐based phenomenon. It argues that there is a great value of knowing how racism works for the development of an anti‐racist and nondiscriminating organization. Although any of the three traditions on ethical thinking does not give direct answer to the question of how…
Alliances between For-Profit and Non-Profit Organizations as an Instrument to Implement the Economy for the Common Good
2020
The model of the Economy for the Common Good (ECG) has cooperation as one of its main principles. This alternative economic model proposes to prioritize cooperation over competition to favor the creation of social value. From this point of view, strategic alliances between organizations can be used as an instrument that supports implementation of the ECG model. In recent years, alliances between for-profit and non-profit entities have been strengthened as a method to facilitate actions focused on social responsibility and sustainability. Moreover, the ECG model has become an adequate management framework for corporate sustainability. This work aims to connect alliances between for-profit an…
Antecedents of team turnover intentions in temporary organizations
2016
Purpose – The purpose of this paper is to shed light on the antecedents of team turnover intentions in temporary organizations such as projects, programs, or temporary teams. Design/methodology/approach – The authors systematically combine the findings from the literature on the antecedents of turnover intentions in permanent organizations (PO) with the characteristics of temporary organizations (TO) and develop a research model comprising personal factors, job-related factors, and organization-related factors. Findings – A research model consisting of testable propositions that the authors derived from both specificities of TO and the antecedents of turnover intentions in PO. Originality/…
Cooperation in Rural Areas as a Local System Development Opportunity
2017
The development of rural areas requires the adoption of technology innovation and market approach strategies without departing from the specific features of local production systems, such as agricultural practices and the wealth of knowledge of operators. It is even better the exploitation of these resources to characterize the competitive positioning of territorial systems. In this framework, the cooperative Rinascita, which works in an internal rural area of Sicily region (Southern Italy), represents an attempt to maintain agricultural activities, traditions and rural culture as well as to promote and contribute to the development of the area by giving value to and promoting, a typical lo…

Entrepreneurial success and human resources
2011
PurposeThis paper aims to determine factors that have an influence on human resource management and entrepreneurial success in the context of European innovative small and medium‐sized enterprises (SMEs).Design/methodology/approachA primary test questionnaire was tested with 50 Spanish entrepreneurs. The feedback from this study was used to improve the survey for a final test. Multivariate regression analysis was used to differentiate the factors that allow the explanation of the variables to be studied and factors that, a priori, seem to be the most relevant in explaining entrepreneurial success.FindingsThe study allows the determination of what factors make the European entrepreneur succe…
