Cooperative communication: efficient schemes and practical aspects

Cooperation has been considered as a key strategy to cater for the ever increasing demand for high data rate wireless communication. Over the past few years, researches in this area have seen a tremendous growth and advancement, where various cooperation strategies were proposed for different communication scenarios. The aim of this thesis is to illustrate the significance of cooperation in improving transmission quality, in which both cooperative broadcasting as well as cooperative relaying context are taken into consideration. An emphasis on the efficiency and practical aspects of different schemes are then given, and novel techniques to improve on both aspects are proposed. In cooperative broadcast communication where each node is equipped with multiple antennas, it is shown that antenna selection can provide an effective solution for hardware complexity and space limitation issues inherent to multi antenna systems. A novel selection scheme for cooperative broadcast communication is then proposed. The scheme takes advantage of uplinkdownlink duality to reduce computational requirement while still achieving most of the gain available. Starting from the single user system, a sub optimal selection strategy is proposed for multicarrier systems as well. Combining with the earlier method developed for cooperative broadcast scenario, effective antenna selection scheme for multicarrier broadcast systems is obtained. Complexity analysis is given to justify its practical aspect, and its performance when applied to Broadband Wireless Access system based on IEEE 802.16 is studied. In cooperative relay communication, different issues are addressed. Starting from the simplest three node scenario, the fundamental question on whether the existence of relay node can improve end-to-end performance is addressed. The importance of power control is demonstrated, and it is shown that in some cases the problem of finding the optimal power distribution can be translated into finding the roots of polynomial equation; which can be solved using any available root finding algorithm.

Disturbi psicopatologici negli adolescenti sottopostia procedimenti penali

Lo studio della prevalenza di disturbi psicologici nei giovani sottoposti a procedimenti penali e utile per orientare le scelte nell’organizzazione dei Servizi della giustizia. La ricerca si propone di determinare la presenza di problemi psicopatologici negli adolescenti che sono presi in carico dai Servizi della giustizia minorile, mettendoli in relazione con il rischio di recidiva. Metodo: Il campione di 66 minori (maschi, eta media 16.3 anni; 35% italiani, 65% stranieri o nomadi), in ingresso nel circuito penale nel 2005 presso i Servizi della giustizia minorile di Milano (detenuti, residenti in comunita alloggio o in carico presso l’Ufficio di servizio sociale per minorenni) e stato valutato attraverso un questionario autosomministrato, la Youth Self Report, e un questionario compilato dagli operatori, la Teacher Report Form (Achenbach, 2001). Risultati: La valutazione da parte degli operatori rileva problemi internalizzanti nel 72% degli adolescenti e una stessa percentuale di esternalizzanti. I risultati del questionario autosomministrato indicano che il 38% degli adolescenti ha problemi esternalizzanti e il 29% internalizzanti. Il confronto tra i disturbi psicopatologici valutati dagli operatori e un indice di rischio di recidiva mostra che il 91,2% degli adolescenti con un alto indice di rischio ha un livello clinicamente significativo di problemi di rilevanza psicopatologica. Conclusioni: I disturbi sono diffusi tra i minori che entrano nel circuito penale. Il fatto che il disagio psicopatologico sia soprattutto presente tra i minori che sono a rischio di recidiva, porta a ritenere che l’intervento psicologico possa essere utile nel ridurre le recidive.
Injectable selenium-containing polymeric hydrogel formulation for effective treatment of myocardial infarction

Myocardial infarction (MI) is a serious threat to people’s life and health, which is significantly hindered by effective treatment formulations. Interestingly, our recent endeavour of designing selenium-containing polymeric hydrogel has been experimentally proved to be helpful in combating inflammatory responses and treating MI. The design was inspired by selenium with anti-inflammatory and anti-fibrosis activities, and the formulation could also serve as a support of myocardial tissue upon the failure of this function. In details, an injectable selenium-containing polymeric hydrogel, namely, poly[di-(1-hydroxylyndecyl) selenide/polypropylene glycol/polyethylene glycol urethane] [poly(DH-SE/PEG/PPG urethane)], was synthesised by combining a thermosensitive PPG block, DH-Se (which has oxidation-reduction properties), and hydrophilic PEG segments. Based on the established mouse model of MI, this formulation was experimentally validated to effectively promote the recovery of cardiac function. At the same time, we confirmed by enzyme-linked immunosorbent assay, Masson staining and Western blotting that this formulation could inhibit inflammation and fibrosis, so as to significantly improve left ventricular remodelling. In summary, a selenium-containing polymeric hydrogel formulation analysed in the current study could be a promising therapeutic formulation, which can provide new strategies towards the effective treatment of myocardial infarction or even other inflammatory diseases.
Compétences individuelles et employabilité : essai de clarification de leur articulation

Si l'employabilite est aujourd'hui reconnue comme un objectif majeur de la gestion des ressources humaines, son operationnalisation et son integration aux pratiques demeure un champ de recherche en construction. La gestion des competences individuelles est l'un des leviers principaux de cette GRH au service de l'employabilite, mais peu de travaux en sciences de gestion integrent competences et employabilite dans leur analyse, et, s'ils le font, ce n'est que depuis peu (Van Der Heijde et al., 2006 ; Wittekind et al., 2010 ; Dietrich, 2010 ; Baruel Bencherqui et al., 2011 ; De Vos et al., 2011 ; Raoult et al., 2011). Cette communication vise a investiguer et clarifier les liens entre ces deux concepts cles en GRH, en proposant des elements de reponse a la question suivante : Comment s'articulent la gestion des competences individuelles et l'employabilite ? A partir d'une revue de la litterature sur la gestion des competences d'une part, l'employabilite d'autre part, puis croisee, nous proposerons trois niveaux d'articulation possible. Tout d'abord, l'articulation conceptuelle s'appuie sur le cadre theorique des capacites dynamiques organisationnelles pour faire emerger le " savoir-evoluer " comme une competence constitutive de l'employabilite. Ensuite, d'un point de vue pratique, l'articulation des competences individuelles et de l'employabilite passe par les demarches de GPEC, offrant le cadre necessaire au developpement de pratiques adaptees d'evaluation, de formation et de mobilite. Enfin, une articulation critique est proposee a partir d'une discussion de la mise en pratique du partage des responsabilites de la gestion des competences des individus et de leur employabilite, ainsi que du developpement de l'image de marque employeur et du marketing de soi.
THE ONE CLICK GROUP

With grave parental concerns over the numerous false Munchausen Syndrome by Proxy accusations laid at the door of parents of children who suffer from the neurological disease ME/CFS (ICD-10 G93.3) and with many of these children having been forcibly removed from their homes, why has a child abuse specialist been put in charge of a children’s ‘CFS/ME’ Centre? Child abuse specialist Dr. Peter Lachman, is heading the children’s ‘CFS/ME’ Centre in Harrow, West London that will deal with ME/CFS children encompassing a very broad area of the city including the boroughs of Brent, Ealing, Hammersmith & Fulham, Harrow, Hillingdon, Hounslow, Kensington & Chelsea. Peter Lachman is the Designated Doctor for Child Protection in Harrow and is a Team Leader for Community Mental Health. The care of numerous vulnerable ME/CFS children will be placed in this man's hands. What is Peter Lachman, an expert in child abuse, DOING running a ‘CFS/ME’ Centre for children bearing in mind the massive controversy and scandal that has for many years surrounded false Munchausen Syndrome by Proxy accusations levied at the parents of ME/CFS children? Precisely what experience has this man got in the field of ME/CFS? Would a child abuse specialist be permitted to apply for funds and run a medical centre devoted to the care of cancer or leukaemia children? How is Lachman’s bid for funds to run this ‘CFS/ME’ children’s centre in any way appropriate or justified? With no previous experience in ME/CFS that we can detect (we can find no papers from Lachman on ME/CFS children published), Lachman’s main area of speciality is child abuse and child protection. He previously practised in South Africa. Nearly all of his published work is in child protection. [1],[2],[3],[4] Lachman acted as an expert witness in the recent Victoria Climbie (child abuse) case.

The role of fascin-1 in the pathogenesis, diagnosis and management of respiratory related cancers

Human cancer statistics report that respiratory related cancers such as lung, laryngeal, oral and nasopharyngeal cancers account for a large proportion of tumors, and tumor metastasis remains the major reason for patient death. The metastasis of tumor cells requires actin cytoskeleton remodeling, in which fascin-1 plays an important role. Fascin-1 can cross-link F-actin microfilaments into bundles and form finger-like cell protrusions. Some studies have shown that fascin-1 is overexpressed in human tumors and is associated with tumor growth, migration and invasion. The role of fascin-1 in respiratory related cancers is not very clear. The main purpose of this study was to provide an updated literature review on the role of fascin-1 in the pathogenesis, diagnosis and management of respiratory related cancers. These studies suggested that fascin-1 can serve as an emerging biomarker and potential therapeutic target, and has attracted widespread attention.
Référents et bricolages identitaires. Histoires de vie d'Italo-Montréalais

Referentes y bricolages identidarios. Las historias de vida de un padre y de un hijo italo-montrealeses Mauro PERESSINI A traves del analisis de los relatos de vida de un inmigrante italo-montreales y de su hijo, este articulo quiere ilustrar a la vez los aspectos metodologicos y algunos resultados de una investigacion mas amplia. En cuanto al metodo, el analisis muestra como interesarse en los personajes a traves de los que los naradores se llevan a la escena en sus relatos, permite hacer mas explicito el sistema identidario de los naradores poniendo de relieve las identidades diferentes que expresan estos personajes, las valoraciones y desvaloraciones de las que son objeto asi como las relaciones que las reunen o las oponen. En cuanto a los resultados, los dos relatos presentados expresan dos universos identidarios distintos cuya explicacin solo puede atribuirse en parte a una diferencia de generacion. La conclusion propone : 1) Considerar la influencia de las trayectorias escolares y socio-economicas en la construccion de la imagen propia que los naradores proponen a su interlocutor ; 2) Explorar tambien como las contradicciones inherentes a la relacion entre generaciones en un contexto inmigrante contribuyen a crear los diferentes universos identidarios considerados.
Réflexions actuelles à propos d'un cas de diabète insulino-dépendant apparu à quatre ans

Issu de ce que l’auteur decrit comme une « conjonction explosive», le diabete insulino-dependant, maladie difficile a vivre et difficile a penser, peut entrainer chez le jeune enfant un appauvrissement de l’appareil psychique. Le cas d’un enfant dont le diabete insulino-dependant est apparu a quatre ans illustre le fait qu’une telle evolution n’est nullement ineluctable.
Problématique et particularités des nouvelles entreprises. Le cas d'Alicante

Cet article analyse les caracteristiques des nouvelles petites entreprises dans la province d’Alicante, en Espagne, notamment durant les annees 80. A partir d'un questionnaire soumis aux nouveaux proprietaires-dirigeants, nous avons voulu connaitre ces entreprises et les caracteristiques de leur dirigeant. Notre enquete s’est arretee d’abord aux profils personnels predominants distinguant ceux-ci de la population, et ensuite aux motifs expliquant leur action. Ces motifs proviennent tant de leurs aspirations personnelles et professionnelles que des besoins et des opportunites economiques. Une fois lancees, les nouvelles entreprises suivent une voie propre avec tout ce que cela entraine et font face a des problemes concrets que nous essayons de definir dans cette etude.
On the locus and spread of pseudo-density functions in the time-frequency plane

Various time-frequency pseudo-density functions used in signal analysis are compared with respect to spread. Among the members of Cohen's class of pseudo-density functions satisfying the finite support property as well as Moyal's formula, the Wigner distribution is the most well-behaved one in the sense that it has the least amount of global spread around its center of gravity. The Wigner distribution does not perform significantly better globally than the real part of Rihaczek's function; it does, though, if the global criterion is replaced by a local one, especially for signals f of the form f(t) equals a(t)exp(2 pi i phi (t)) where phi is a smooth real-valued function and a is a slowly varying positive function. A general principle is formulated according to which the various pseudo-density functions of f should be concentrated around the curve (t, phi prime (t)). A more detailed qualitative analysis of the behavior of the Wigner distribution of f around this curve is included.
Prehospital trauma care systems

The World Health Organization (WHO) was established in 1948 as a specialized agency of the United Nations (UN) serving as the directing and coordinating authority for international health matters and public health. One of WHO's constitutional functions is to provide objective and reliable information and advice in the fi eld of human health, a responsibility that it fulfi ls in part through its extensive programme of publications. The Organization seeks through its publications to support national health strategies and address the most pressing public health concerns of populations around the world. To respond to the needs of Member States at all levels of development, WHO publishes practical manuals, handbooks and training material for specifi c categories of health workers; internationally applicable guidelines and standards; reviews and analyses of health policies, programmes and research; and state-of-the-art consensus reports that offer technical advice and recommendations for decision-makers. These books are closely tied to the Organization's priority activities, encompassing disease prevention and control, the development of equitable health systems based on primary health care, and health promotion for individuals and communities. Progress towards better health for all also demands the global dissemination and exchange of information that draws on the knowledge and experience of all WHO's Member countries and the collaboration of world leaders in public health and the biomedical sciences. To ensure the widest possible availability of authoritative information and guidance on health matters, WHO secures the broad international distribution of its publications and encourages their translation and adaptation. By helping to promote and protect health and prevent and control disease throughout the world, WHO's books contribute to achieving the Organization's principal objective—the attainment by all people of the highest possible level of health. The designations employed and the presentation of the material in this publication do not imply the expression of any opinion whatsoever on the part of the World Health Organization concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.

Manipulator joint independent control and its structural stability

In spite of non-linearities and couplings existing in robot dynamics, local linear feedback schemes such as PD laws have been successfully used in motion control of non-direct drive robot manipulators with high gear ratios. This paper is motivated by finding out trajectory tracking stability conditions for this sort of joint independent control systems in terms of robot dynamic parameters such as motor shift inertia, arm inertia and gear ratios of the transmission. It shows that when the gear ratios of a robot manipulator with n joints are considerably high the overall non-linear system can be approximated by n decoupled subsystems dominated by servo motor dynamics and therefore be controlled by a independent local linear feedback controllers. The paper also shows the local stability condition and the boundedness of the trajectory tracking error if a system is stable. <<ETX>>
Reducing the number of dispensing errors by implementing a combination of a CPOE system and a bar-code-assisted dispensing system: the BAP concept

Introduction: Medication errors occur frequently in hospitals. A computerised prescriber order entry (CPOE) system together with bar-code-assisted dispensing can reduce the error rate. Method: A complete business process redesign was undertaken and evaluated in two steps. Using a direct observer method to detect dispensing errors by nurses, the impact on patient safety of the implementation of a CPOE system (step 1) combined with bar-code-assisted dispensing (step 2, using bedside assortment picking [BAP]) was investigated. Results and discussion: The implementation of a CPOE system resulted in a reduction in the dispensing error rate of 47% in comparison with the pre-CPOE phase (from 3.1% to 1.7%). BAP resulted in an additional reduction in dispensing errors of 49% (from 1.7% to 0.84%). Overall, a reduction of errors of 73% was obtained. Conclusion: The BAP concept was able to improve medication safety in the hospital significantly.
The effect of training life expectancy and coping styles on negative emotions of cardiac surgical patients' mental health

Background and Purpose: Cardiovascular diseases are the most common causes of death worldwide and stress is the reason behind many negative emotions. Surgery is one of the most stressful situations. Coping styles and life expectancy affect people's mental and physical efficacy. The present study aims to determine the effectiveness of training life expectancy and effective coping styles to deal with negative emotions on cardiac surgery patients' mental health at Sari-based Fateme Zahra Hospital in 2013. Methods: In this quasi-experimental study, 30 candidates for coronary artery bypass surgery referring to this center was selected using the available sampling method. They were then randomly included into two 15-member groups as experimental and control group. Stress management, anger management, and hopefulness training courses were held individually for 7 sessions. Before and after the intervention, the patients of both groups answered the questionnaires including the Coping Manners Questionnaire (by Lazarus & Folkman), Snyder’s Hope Scale, and the General Health Questionnaire-12 (GHQ-12). Results: Data analysis implied that there is a significant difference between the average general health in the experimental and control groups after training. Investigating the subscales of coping strategies in the experimental and control groups after training showed that there is a significant difference between direct coping, planned problem solving, and positive reappraisal in the two groups. Conclusions: In patients with coronary heart disease, high stress, and negative emotions (anger, anxiety, depression) also as the candidates of coronary artery bypass surgery, training raised life expectancy level and the practical methods for coping with life can be great help to their mental health condition.
A Sentiment-Based Digital Library of Movie Review Documents Using Fedora / Une bibliothèque numérique de documents critiques de films basée sur les sentiments en utilisant Fedora

This study develops a digital library of movie review documents that supports sentiment-based browsing and searching. Firstly, we develop an automatic method for in-depth sentiment analysis and classification of movie review documents to provide sentiment orientations toward multiple perspectives of movies, such as overall opinion about the movie, director, and cast. By utilizing information extraction techniques such as entity extraction, co-referencing, and pronoun resolution, the review texts are segmented into multiple sections where each section contains multiple sentences and discusses a particular aspect of the reviewed movie. For each aspect section, a machine-learning algorithm, Support Vector Machine (SVM), is applied to determine sentiment orientation toward the target aspect. Secondly a prototype digital library is developed with the automatically analysed data to show the usefulness of sentiment-based browsing and searching. Using the system, the user can browse and search movies by sentiment polarity (positive, neutral, or negative) of multiple aspects in the movie. Finally, a usability evaluation is conducted to observe the effectiveness of the sentiment-based digital library. Cette étude examine le développement d’une bibliothèque numérique de documents critiques de films permettant l’exploration et la recherche par sentiments. Pour commencer, nous développons une méthode automatique pour l’analyse en profondeur des sentiments et la classification des documents critiques de films propres à fournir des orientations à propos des sentiments capables d’offrir des perspectives multiples sur les films, comme par exemple l’opinion générale sur le film, sur le metteur en scène, et sur les acteurs. Grâce à l’utilisation de techniques d’extraction d’information telles que l’extraction d’entités, le co-référencement, et la résolution de pronoms, les comptes rendus sont segmentés en de multiples sections où chacune contient plusieurs phrases et aborde un aspect particulier du film en question. À chacune de ces sections on applique un algorithme d’apprentissage automatique, Support Vector Machine (SVM), qui détermine l’orientation du ou des sentiments pour cette section. Ensuite, nous développons un prototype de bibliothèque numérique en utilisant les données analysées automatiquement afin de montrer l’utilité de l’exploration et de la recherche par sentiments. En utilisant ce système, l’utilisateur peut explorer et faire des recherches dans les films selon les polarités des sentiments (positif, neutre, ou négatif) et ce, sur de nombreux aspects des films. Pour finir, nous avons effectué une évaluation d’utilisabilité afin de vérifier l’efficacité d’une bibliothèque numérique basée sur les sentiments.
