The Wine Attributes with the Greatest Influence in the Process of Consumer Choice in Spain
The commercialisation of wine in Spain is problematic due to two concrete circumstances: the decrease in wine consumption because of a consumer shift toward substitute drinks and the greater presence of national and foreign wine in the interior market, which involves an increase in business competitiveness. The increase in competitiveness of quality Spanish wine depends on producing enterprises’ knowledge of wine consumer preferences so they can offer consumers what they demand. In order to respond to this matter and better adapt supply, 421 wine consumers were surveyed using the Best-Worst Scaling methodology. Various segmentations were also made by consumer income and age groups. The results indicate that the two main attributes which condition consumers in choosing wine are the region of origin and having tasted it previously. The region of origin attribute is valued in general by consumers over 34 years old who have a monthly family income above 1,500 €. The attribute of having tasted it before, which on many occasions is associated with the price attribute, is valued particularly by younger consumers and those with lower incomes.Consumer behaviour, Wine attributes, Food Marketing, Consumer/Household Economics,
Transtubular Resection of Spinal Intradural Lésions : Techniques, Results, & Complications.
Le travail de thèse ici présenté a été publié sous forme d’un article scientifique ayant le titre « Image guided tailored access resection (IMTAR) of spinal intradural tumors. Technical report of 13 cases »
L’article présente les résultats de la chirurgie per « accès minime » (MAS) utilisée dans notre établissement hospitalier avec une implémentation de la technique guidée par image que nous appelons « technique de navigation chirurgicale guidée par fusion d’image » (en anglais : Image Merge Tailored Access Resection ou IMTAR). IMTAR représente l’application d’une technique de fusion d’image déjà existante pour la chirurgie crânienne qui consiste à fusionner les images de la résonance magnétique préopératoire avec les images de fluoroscopie 3D obtenues pendant la chirurgie pour naviguer à la fois les structures osseuses et les tissus mous. La fusion d’image donne au chirurgien la possibilité de mieux planifier l’accès chirurgical par la navigation virtuelle sur les images avant l’incision. Le chirurgien peut donc adapter l’abord chirurgical selon la localisation de la lésion et également adapter la résection d’os en fonction de la fenêtre d’exposition nécessaire pour la visualisation de la lésion tumorale. Le choix d’utiliser la technique IMTAR est pris en préopératoire par le chirurgien en fonction de la disponibilité de cette technique dans un contexte de chirurgie élective. La technique est une implémentation d’une technique déjà existante et bien validée par la littérature courante dont l’utilisation est faite au niveau crânien, mais ici adaptée à la chirurgie spinale.
L’utilisation de la technique IMTAR a pour but de réduire le risque d’erreur de niveau de la localisation des lésions tumorales spinales, situation décrite en littérature. De plus, le choix de trajectoire d’accès trans-musculaire selon la localisation de la lésion tumorale pourrait améliorer l’angle d’accès aux lésions et minimiser le volume d’os enlevé pendant l’abord chirurgical.
Sur la série préliminaire de 13 patients dont les résultats sont contenus dans l’article ici joint, la technique IMTAR a montré des résultats d’exérèse tumorale superposables aux résultats de la technique MAS non-naviguée. La procédure IMTAR semble être moins invasive en termes de résection osseuse et elle permet une meilleure localisation de la lésion.
Le présent travail de thèse s’est déroulé dans le contexte de l’étude IMTAR, catégorie A (Protocole n. 172/15) approuvé par le CER VD et en cours depuis 01.01.2017 au CHUV de Lausanne (investigateurs principales: Dr Rodolfo Maduri, Dr John Michael Duff).
Les perspectives futures pour cette étude sont de décrire les résultats chirurgicaux sur une « prospective cohort » de patients ayant bénéficié de la technique IMTAR et de la technique MAS non-naviguée jusqu’à la date de fin de l’étude.
L’étude IMTAR a pour but d’évaluer les résultats de l’utilisation de la technique IMTAR pour les tumeurs spinales par rapport à la technique de chirurgie MAS classique en termes de minimisation de la morbidité associée à l’abord chirurgical, de la réduction du risque d’une instabilité spinale iatrogène et de l’optimisation de l’efficacité de la résection de la tumeur.

- OBJECTIVE: Standard translaminar approaches for intradural extramedullary (IDEM) tumors require extensive soft tissue dissection and partial facet removal. Ventral lesions may necessitate wider bone resection with sub- sequent possible spinal instability. Any manipulation of an already compromised spinal cord may lead to neurological injury. We describe an image-guided minimal access technique for IDEM tumor resection.
- METHODS: Retrospective chart review of 13 consecutive patients after institutional ethics committee approval. We superimpose preoperative magnetic resonance imaging data with intraoperative 3-dimensional fluoroscopic im- ages, allowing to simultaneously visualize osseous anat- omy and the soft tissue lesion using appropriate windowing. We then plan optimal angle of trajectory to the tumor, which defines the skin incision and the trans- muscular trajectory. A tubular retractor is placed to span the tumor. Microsurgical tumor resection is then carried out using this angle of approach.
- RESULTS: Thirteen patients (mean age. 57 years; male-to- female ratio, 10:3) were operated on during 28 months. Gross total resection was achieved in all patients. Neuro- logical improvement occurred in 12 of the 13 patients. There was no neurological deficit outside of the expected sensory loss due to intentional nerve root sacrifice. No mechanical pain nor tumor recurrence were noted during the follow-up (mean, 16 months; range, 2e30 months).
- CONCLUSIONS: Image merge tailored access resection appears to be at least equivalent in terms of tumor resec- tion, blood loss, and complications to other tubular tech- niques. It may reduce risks of neurological deficit and spine instability. Image merge tailored access resection is a novel application of merging intraoperative fluoroscopic images with preoperative magnetic resonance images for tailored IDEM resection

How corporate governance and globalization can run afoul of the law and good practices in business: The Enron's disgraceful affair.
The purpose of this paper is to set out the Enron’s demise into the perspective of Corporate and Global Governance. To accomplish this target, the incremental cash flow model is expanded to give room for governance issues, while a functional introduction to information sets is developed, including bounded rationality, asymmetric information, opportunistic behavior, transaction costs and agency problems. Then, corporate governance is linked to globalization by means of some recent approaches that go beyond a narrow economic mindset to encompass a far-reaching dynamics. Taking advantage of such background, the Enron’s story is tracked down over a span of fifteen years since its starting day to its bankruptcy filing. Leading events are explained from corporate and global governance viewpoints, while an in-depth analysis is worked out on Enron’s complex game of deception and breach of contracts: the outrageous affiliated limited partnerships, the lavish pay package to its executives, the involvement with global governance through the Indian affair and the Taliban connection. It is for the incremental cash flow model to explain malfeasance with cash flows from assets, and how cash flows to creditors were actually contrived. Furthermore, to highlight how cash flows were swindled from stockholders and, finally, how Enron made wheeling and dealing with cash flows on behalf of its managers.corporate governance, global governance, incremental cash flow model, globalization, information sets, good practices.

El funcionalismo de rodolfo lenz
Summary
This paper deals with the contributions to Hispanic Linguistics by the German-Chilean linguist Rodolfo Lenz (1863–1935), some of whose proposals – often attributed to other scholars – may be seen as an alternative to the ideas of the prestigious Andrés Bello (1781–1865). The paper first reviews those aspects of his work which anticipate some of the basic tenets of Functional Grammar, such as the notion of ‘transposition’ (function shifting), his views on sentential structure, and his treatment of passives as attributive constructions. The paper also explores Lenz’s contributions to Indo-European linguistics and his theoretical affinities with, if not anticipations of, the work of other well-known linguists like Búhler, Tesnière, Hjelmslev, and Benveniste. In sum, the author seeks to vindicate Rodolfo Lenz and his insightful views in both general linguistic theory and Spanish grammar.</jats:p
Complications after surgery for chronic subdural hematomas
Chronic subdural hematoma (CSDH) is an increasing issue worldwide, due to the increasing age of the population. Despite the simple surgical technique it may be burdened by a high rate of complications (such as recurrence, acute rebleeding, infections, . ..). A consensus about the right management of those events. In this chapter we clarify what are the most common complications of CSDH through a literature review and through a description of some clinical cases in order to better udestand these problems

Cranioplasty With Hydroxyapatite Implants: A Multidisciplinary Approach of Neurosurgeon and Plastic Surgeons to Improve Surgical Technique and Clinical Outcome
Cranioplasty using Hydroxyapatite prosthesis is a conceptually simple procedure, but it may harbor several challenges for the surgeons. Several papers in the literature deal with cranioplasty using porous hydroxyapatite. The results are not homogeneous both because of the variability of the patients treated but also because Hydroxyapatite requires a more careful surgical technique to achieve maximum performance. The aim of the present study is to offer an insight of a single institution, multidisciplinary experience with custom-made Hydroxyapatite cranioplasty with surgical tips and tricks based on personal opinion and literature evidence. We will provide an overview of all the fundamental steps we believe to be useful to optimize surgical outcomes, including preoperative planning of cranioplasty; as cranioplasty flap/soft tissue coverage planning, infectious prophylaxis, patient positioning, incisional patterns, tissue dissection, primary bone demolition, and preparation of the craniectomy margins before implant positioning. The authors will also discuss methods for dural suspension, implant fixation and anchorage, margins polishing, drainage, suturing, and dressing. Cranioplasty using hydroxyapatite prosthesis is a valuable alternative for skull reconstruction with heterologous implants, and in our opinion a multidisciplinary approach integrating plastic surgeons and neurosurgeons' specific skills can facilitate surgical planning, reducing complications and allowing to achieve better functional and aesthetic results
