Fonaments i actuacions de lideratge sistèmic d'un equip de bàsquet professional i futures aplicacions

El treball de recerca “Fonaments i actuacions de lideratge sistèmic d’un equip de bàsquet professional i futures aplicacions” fa l’anàlisi d’una experiència real vinculada al món de l’esport professional. Es pretén donar a conèixer com l’estructuració del coneixement de l’entrenador pot afavorir el bon funcionament de l’equip. L’estructuració ens genera criteri i coherència a l’hora de prendre decisions.Es reconeix a l’entrenador com una persona treballadora, apassionada per la seva feina i en constant creixement individual. Valors com la humilitat, l’entusiasme, el compromís, la generositat i l’autoexigència es converteixen en adjectius fonamentals del nostre entrenador.L’estudi en l’autoconeixement en conceptes com lideratge, nivells neurològics, talent i motivació esdevenen el pal de paller en la construcció de l’equip. Un equip amb identitat pròpia, on el benefici pel bé comú (equip) està per sobre de tot, cooperatiu, compromès, i on la figura de l’entrenador intuïtiu amb coneixement influeix més per convenciment que per autoritat.El treball del dia a dia de l’entrenador i de l´equip es fonamenta en l’organització dels pilars de l’entrenador: flexibilitat, creixement de l’entrenador, equip, marges col·lectiu i individual són els motors del bon funcionament del col·lectiu. En el treball presentat, es destaca la importància de saber diferenciar, en el rendiment d’un equip, dues vessants: una més objectiva (tècnica, tàctica, estratègia i física) i l’altra on el factor humà és determinant. La investigació aprofundeix en aquest segon factor i el reconeix com a preferent. Per acabar es presenten tot un seguit d’actuacions utilitzades al llarg de la investigació amb la finalitat de generar, mantenir i millorar l’equip al mateix temps que es mostren diferents eines per tal d’optimitzar l’eficiència de les actuacions. La investigació pretén ser una experiència útil i enriquidora a l’hora d’estructurar el coneixement per tal de poder ser utilitzat en futures aplicacions.

Coevolutionary networks: a novel approach to understanding the relationships of humans with the infectious agents

Human organism is interpenetrated by the world of microorganisms, from the conception until the death. This interpenetration involves different levels of interactions between the partners including trophic exchanges, bi-directional cell signaling and gene activation, besides genetic and epigenetic phenomena, and tends towards mutual adaptation and coevolution. Since these processes are critical for the survival of individuals and species, they rely on the existence of a complex organization of adaptive systems aiming at two apparently conflicting purposes: the maintenance of the internal coherence of each partner, and a mutually advantageous coexistence and progressive adaptation between them. Humans possess three adaptive systems: the nervous, the endocrine and the immune system, each internally organized into subsystems functionally connected by intraconnections, to maintain the internal coherence of the system. The three adaptive systems aim at the maintenance of the internal coherence of the organism and are functionally linked by interconnections, in such way that what happens to one is immediately sensed by the others. The different communities of infectious agents that live within the organism are also organized into functional networks. The members of each community are linked by intraconnections, represented by the mutual trophic, metabolic and other influences, while the different infectious communities affect each other through interconnections. Furthermore, by means of its adaptive systems, the organism influences and is influenced by the microbial communities through the existence of transconnections. It is proposed that these highly complex and dynamic networks, involving gene exchange and epigenetic phenomena, represent major coevolutionary forces for humans and microorganisms.

Narrative Diagrammatik. Mit einer Modellanalyse: Die Diagrammatik des "Decameron"

Taking as a starting point the seeming inconsistency of late-medieval romances notoriously 'run wild' (verwildert), this article is concerned with the description of an abstract form of narrative coherence that is based on the notion of the diagrammatic. In a first section, this concept is illustrated in a simplified manner by an analysis of Boccaccio's Decameron based on two levels of spatial structure: that of the autograph Berlin manuscript (Codex Hamilton 90) and that of the recipient's mental visualisation of the relations between the frame and the tales of the work. It is argued that the connectivity of the work as a whole depends on the perception of those two spatial representations of the plot. A second section develops this concept in a more theoretical fashion, drawing on Charles Sanders Peirce's notion of diagrammatic reasoning as a way of perceiving relations through mental and material topological representations. Correspondingly, a view of narrative is proposed that does not depend on the traditional perspective of temporal sequence but emphasizes the spatial structure of literary narrative. It is argued that these conditions form the primary ontological mode of narrative, whereas the temporal development of a story is an aesthetic illusion that has been specifically stimulated by the narrative conventions of approximately the past three centuries and must thus be considered a secondary effect. To conclude, an interpretation in miniature of an aspect of Heinrich von Neustadt's Apollonius von Tyrland that seems to have 'run wild' is undertaken from a diagrammatic perspective.

La construcción social de las emociones en las sociedades occidentales: el amor materno en la Catalunya del siglo XXI

El objetivo principal de esta investigación es analizar la forma cómo se construye socialmente el amor materno en el marco de las sociedades occidentales, y para ello partiremos del estudio del caso de las maternidades en la Catalunya actual. El amor materno, como emoción, aparece como una codificación cultural que responde a la canalización de la vida que cada cultura establece. En las sociedades occidentales el amor materno se revela como uno de los ejes vertebradores y legitimadores de la esfera reproductiva y del papel de la mujer dentro de ésta, definiéndose en consonancia y dando coherencia al resto de aspectos del sistema social. Dada su importancia los discursos hegemónicos de la sociedad que lo define tienden a naturalizar esta emoción en favor del mantenimiento y el no cuestionamiento del orden social dado, a pesar de que abundante evidencia empírica en ciencias sociales demuestra que se trata de una construcción social que responde a las necesidades del sistema social en cuestión. Actualmente los discursos tradicionales que contenían y definían la concepción de amor materno en Occidente se han ampliado y diversificado debido a cambios sociales como el ingreso de la mujer en la esfera pública; el logro de igualdad jurídica entre géneros; cambios en los modelos familiares; nuevas situaciones en torno a la infancia y la juventud; la intensificación de los flujos migratorios; la creciente urbanización; la expansión de los servicios públicos (escuela y salud); el alargamiento de la esperanza de vida, los métodos anticonceptivos modernos..., de manera tal que muchos de ellos entran en contraposición con las definiciones tradicionales. Es decir, nuevos y viejos discursos alrededor de la maternidad se encuentran enfrentados en su redefinición a otros que lo cuestionan, y a prácticas y cambios en ciertas instituciones que llevan en otra dirección la construcción de esta emoción. Esta nueva situación, aún en fase de conformación, reclama una explicación que pasa por conocer las causas, las formas y la definición del amor materno, en nuestro actual contexto.

A multi-perspective approach to performance anxiety in music students

AbstractPerforming publicly has become increasingly important in a variety of professions. This condition is associated with performance anxiety in almost all performers. Whereas some performers successfully cope with this anxiety, for others it represents a major problem and even threatens their career. Musicians and especially music students were shown to be particularly affected by performance anxiety.Therefore, the goal of this PhD thesis was to gain a better understanding of performance anxiety in university music students. More precisely, the first part of this thesis aimed at increasing knowledge on the occurrence, the experience, and the management of performance anxiety (Article 1). The second part aimed at investigating the hypothesis that there is an underlying hyperventilation problem in musicians with a high level of anxiety before a performance. This hypothesis was addressed in two ways: firstly, by investigating the association between the negative affective dimension of music performance anxiety (MPA) and self-perceived physiological symptoms that are known to co-occur with hyperventilation (Article 2) and secondly, by analyzing this association on the physiological level before a private (audience-free) and a public performance (Article 3). Article 4 places some key variables of Article 3 in a larger context by jointly analyzing the phases before, during, and after performing.The main results of the self-report data show (a) that stage fright is experienced as a problem by one-third of the surveyed students, (b) that the students express a considerable need for more help to better cope with it, and (c) that there is a positive association between negative feelings of MPA and the self-reported hyperventilation complaints before performing. This latter finding was confirmed on the physiological level in a tendency of particularly high performance-anxious musicians to hyperventilate. Furthermore, the psycho-physiological activation increased from a private to a public performance, and was higher during the performances than before or after them. The physiological activation was mainly independent of the MPA score. Finally, there was a low response coherence between the actual physiological activation and the self-reports on the instantaneous anxiety, tension, and perceived physiological activation.Given the high proportion of music students who consider stage fright as a problem and given the need for more help to better cope with it, a better understanding of this phenomenon and its inclusion in the educational process is fundamental to prevent future occupational problems. On the physiological level, breathing exercises might be a good means to decrease - but also to increase - the arousal associated with a public performance in order to meet an optimal level of arousal needed for a good performance.

Saponins from Swartzia langsdorffii: biological activities

The presence of saponins and the molluscicidal activity of the roots, leaves, seeds and fruits of Swartzia langsdorffii Raddi (Leguminosae) against Biomphalaria glabrata adults and eggs were investigated. The roots, seeds and fruits were macerated in 95% ethanol. These extracts exerted a significant molluscicidal activity against B. glabrata, up to a dilution of 100 mg/l. Four mixtures (A2, B2, C and D) of triterpenoid oleanane type saponins were chromatographically isolated from the seed and fruit extracts. Two known saponins (1 and 2) were identified as beta-D-glucopyranosyl-[alpha-L-rhamnopyranosyl-(1->3)- beta-D-glucuronopyranosyl-(1->3)]-3beta-hydroxyolean-12-ene-28 -oate, and beta-D-glucopyranosyl-(1->3)-beta-D-glucuronopyranosyl-(1 ->3)]-3beta-hydroxyolean-12-ene-28-oate, respectively. These two saponins were present in all the mixtures, together with other triterpenoid oleane type saponins, which were shown to be less polar, by reversed-phase HPLC. The saponin identifications were based on spectral evidence, including ¹H-¹H two-dimensional correlation spectroscopy, nuclear Overhauser and exchange spectroscopy, heteronuclear multiple quantum coherence, and heteronuclear multiple-bond connectivity experiments. The toxicity of S. langsdorffii saponins to non-target organisms was prescreened by the brine shrimp lethality test.

Modular analysis of gene expression data with R.

SUMMARY: Large sets of data, such as expression profiles from many samples, require analytic tools to reduce their complexity. The Iterative Signature Algorithm (ISA) is a biclustering algorithm. It was designed to decompose a large set of data into so-called 'modules'. In the context of gene expression data, these modules consist of subsets of genes that exhibit a coherent expression profile only over a subset of microarray experiments. Genes and arrays may be attributed to multiple modules and the level of required coherence can be varied resulting in different 'resolutions' of the modular mapping. In this short note, we introduce two BioConductor software packages written in GNU R: The isa2 package includes an optimized implementation of the ISA and the eisa package provides a convenient interface to run the ISA, visualize its output and put the biclusters into biological context. Potential users of these packages are all R and BioConductor users dealing with tabular (e.g. gene expression) data. AVAILABILITY: http://www.unil.ch/cbg/ISA CONTACT: sven.bergmann@unil.ch

Fully engaged: tackling health inequalities through public health interventions

The evolving role of Primary Care Trusts (PCTs) is currently centre stage, with fundamental debate emerging from Commissioning a patient-led NHS and Our health, our care, our say a new direction for community services. This paper argues that PCTs have a crucial role to play in the public health agenda, specifically tackling health inequalities. This responsibility will become even stronger as the present wave of reforms gains momentum. There is also a lively debate on whether these reforms will make inroads into the persistent problem of health inequality or will exacerbate them even further unless robust, additional intervention levers and mechanisms are introduced. This paper suggests that PCTs will be central to ensuring the balance of reforms is tilted towards a more rather than a less equitable NHS. One of the key responsibilities for PCTs outlined by the Department of Health1 will be to act as the anchor at local level to the increasingly diverse and potentially3fragmented NHS. By using their crucial commissioning role to provide overall coherence to the health system, acting as leading local champions of the NHS and continuing the drive for improvement in access and quality, PCTs will have to act as enforcer and guardian of the equity of the NHS at local level. There is widespread evidence of the tenacity of health inequalities in Great Britain. This report looks at the measures that a fully engaged۝3 PCT has taken to grapple with the issues and draws some conclusions as to their possible wider application.refer to the resource

Synchronization of EEG: bivariate and multivariate measures.

Synchronization behavior of electroencephalographic (EEG) signals is important for decoding information processing in the human brain. Modern multichannel EEG allows a transition from traditional measurements of synchronization in pairs of EEG signals to whole-brain synchronization maps. The latter can be based on bivariate measures (BM) via averaging over pair-wise values or, alternatively, on multivariate measures (MM), which directly ascribe a single value to the synchronization in a group. In order to compare BM versus MM, we applied nine different estimators to simulated multivariate time series with known parameters and to real EEGs.We found widespread correlations between BM and MM, which were almost frequency-independent for all the measures except coherence. The analysis of the behavior of synchronization measures in simulated settings with variable coupling strength, connection probability, and parameter mismatch showed that some of them, including S-estimator, S-Renyi, omega, and coherence, aremore sensitive to linear interdependences,while others, like mutual information and phase locking value, are more responsive to nonlinear effects. Onemust consider these properties together with the fact thatMM are computationally less expensive and, therefore, more efficient for the large-scale data sets than BM while choosing a synchronization measure for EEG analysis.

Phenotype in Two Consanguineous Tunisian Families With non Syndromic Autosomic Recessive Retinitis Pigmentosa Caused by an USH2A Mutation

Purpose: To assess the clinical phenotype in two consanguineous Tunisian families with non syndromic autosomic recessive retinitis Pigmentosa (arRP) caused by an USH2A mutation.Methods: All accessible members of family A and B were included and underwent full ophthalmic examination with best corrected Snellen visual acuity, kinetic visual field testing, fundus photography, optical coherence tomography and full field electroretinography. Haplotype analyses were used to test linkage in the families to 20 arRP loci, including ABCA4, LRAT, USH2A, RP29, CERKL, CNGA1, CNGB1, CRB1, EYS, RP28, MERTK, NR2E3, PDE6A, PDE6B, RGR, RHO, RLBP1, TULP1. In addition, index patients were sent to AsperOphthalmics for arRP mutation screening.Results: Twenty three patients from the two families were ascertained for the study. Eight of the 23 members were clinically affected with arRP without hearing loss. Age range at baseline was 35 to 63 years (mean age was 46.5 years). For all affected members, night blindness appeared during the second decade. Visual acuity at baseline ranged from 20/50 to 20/32. Kinetic visual field was severely constricted. Fundus examination revealed typical RP changes with bone spicule-shaped pigment deposits in the mid periphery along with atrophy of the retina, narrowing of the vessels and waxy optic discs. Tomograms showed a thinning and even loss the outer nuclear layer of the fovea. ERG was unrecordable in scotopic conditions and the cone responses were markedly hypovolted. Haplotype analysis did not reveal any homozygosity. Screening at AsperOphthalmis showed a compound heterozygous [p.A1953G]+[p.I5126T] in family A and [p.G713R]+[p.W4149R] in family B.Conclusions: For these families, changes were typical of those that have been described in patients with moderate to severe forms of non syndromic recessive RP. Our findings support the need to consider possible involvement of USH2A not only in patients with Usher syndrome but also in patients with non syndromc arRP. Despite consanguinity, the presence of non-homozygous mutants illustrates the complexity of molecular analysis.

Early clinical experience with ranibizumab for occult and minimally classic neovascular membranes in age-related macular degeneration.

BACKGROUND: In large randomized multicenter trials, ranibizumab has shown its therapeutic efficacy for exudative age-related macular degeneration (AMD). The aim of this paper is to report the real-life clinical experience with this treatment for occult and minimally classic membranes without pigment epithelium detachment. METHODS: We conducted a retrospective chart review of 37 patients with occult and minimally classic neovascular membranes in AMD, without pigment epithelium detachment. RESULTS: The mean visual improvement of 2 lines at 3, 6 and 9 months corresponds well with the results of the large trials. A mean number of 5 reinjections was reached by month 8. It may potentially exceed the mean 5.5 injections of the PrONTO study (prospective optical coherence tomography imaging of patients with neovascular AMD treated with intraocular ranibizumab). At months 6-8 recurrence was frequently observed. CONCLUSION: The early experience of ranibizumab in clinical practice brings similarly good results as the large-scale trials. However, interrupting the treatment too early may be a disadvantage.

El Pla d'Acollida de Centre : una proposta intercultural del tractament a la diversitat

El projecte recull un treball d'assessorament en centres de primària pel que fa a l'elaboració del pla d'acollida. L'assessorament tenia una doble finalitat: dotar el centre d'una eina que el permetés sistematitzar-la i dotar de coherència i continuïtat els dubtes o angoixes que aquesta situació provocava. La base teòrica és doble: l'enfocament constructivista de l'assessorament psicopedagògic i la perspectiva de l'interculturalisme, atès el vessant socialitzador, interactiu i harmonitzador del PdA i la consideració social i sistèmica dels dos referents. La metodologia utilitzada ha estat qualitativa: la investigació-acció, ja que és un assessorament orientat cap a l'acció i basat en la pràctica, amb la finalitat de capacitar els docents en la millora d'aquesta pràctica. Recull aspectes organitzatius -matriculació, adscripció al curs, acollida i relació entre la família i el centre, llengua, recursos interns i suports externs- i coordinacions i estratègies d'aula -acollida, organització i funcionament de la classe, planificació de l'escolarització i activitats. Van quedar pendents de realitzar els aspectes referents al currículum i a la cooperació amb l'entorn.

Pandemic influenza control in Europe and the constraints resulting from incoherent public health laws.

Background With the emergence of influenza H1N1v the world is facing its first 21st century global pandemic. Severe Acute Respiratory Syndrome (SARS) and avian influenza H5N1 prompted development of pandemic preparedness plans. National systems of public health law are essential for public health stewardship and for the implementation of public health policy[1]. International coherence will contribute to effective regional and global responses. However little research has been undertaken on how law works as a tool for disease control in Europe. With co-funding from the European Union, we investigated the extent to which laws across Europe support or constrain pandemic preparedness planning, and whether national differences are likely to constrain control efforts. Methods We undertook a survey of national public health laws across 32 European states using a questionnaire designed around a disease scenario based on pandemic influenza. Questionnaire results were reviewed in workshops, analysing how differences between national laws might support or hinder regional responses to pandemic influenza. Respondents examined the impact of national laws on the movements of information, goods, services and people across borders in a time of pandemic, the capacity for surveillance, case detection, case management and community control, the deployment of strategies of prevention, containment, mitigation and recovery and the identification of commonalities and disconnects across states. Results Results of this study show differences across Europe in the extent to which national pandemic policy and pandemic plans have been integrated with public health laws. We found significant differences in legislation and in the legitimacy of strategic plans. States differ in the range and the nature of intervention measures authorized by law, the extent to which borders could be closed to movement of persons and goods during a pandemic, and access to healthcare of non-resident persons. Some states propose use of emergency powers that might potentially override human rights protections while other states propose to limit interventions to those authorized by public health laws. Conclusion These differences could create problems for European strategies if an evolving influenza pandemic results in more serious public health challenges or, indeed, if a novel disease other than influenza emerges with pandemic potential. There is insufficient understanding across Europe of the role and importance of law in pandemic planning. States need to build capacity in public health law to support disease prevention and control policies. Our research suggests that states would welcome further guidance from the EU on management of a pandemic, and guidance to assist in greater commonality of legal approaches across states.

PACHYCHOROID: an inherited condition?

PURPOSE: Thick choroid (pachychoroid) is associated with central serous chorioretinopathy (CSC), but whether pachychoroid is inherited is unknown. METHODS: In a prospective observational study, first- or second-degree relatives (16 individuals) of 5 patients with CSC had refraction and visual acuity measurement, fundus examination, nonmydriatic photography, and autofluorescence photography. Eyes were graded using the following criteria: 0: normal fundus and autofluorescence photography, 1: focal retinal pigment epithelium hyperfluorescence and/or hypofluorescence and/or retinal pigment epithelial detachment, 2: CSC or diffuse retinal epitheliopathy. Choroid thickness was measured by enhanced depth imaging mode on optical coherence tomography. RESULTS: Considering 395 μm as the threshold limit for normal subfoveal choroidal thickness, 50% of the eyes from relatives had a thick choroid. Nine eyes of Grade 0 (28%) with an isolated pachychoroid would thus have been considered normal, if choroidal thickness was not included as a screening sign predisposing for CSC. CONCLUSION: Our observation suggests that pachychoroid could be an inherited condition with potentially a dominant transmission mode. Its inclusion in the phenotype of CSC for genetic studies should be considered.

A method to obtain the integrated contour image in colour scenes

This paper describes a method to achieve the most relevant contours of an image. The presented method proposes to integrate the information of the local contours from chromatic components such as H, S and I, taking into account the criteria of coherence of the local contour orientation values obtained from each of these components. The process is based on parametrizing pixel by pixel the local contours (magnitude and orientation values) from the H, S and I images. This process is carried out individually for each chromatic component. If the criterion of dispersion of the obtained orientation values is high, this chromatic component will lose relevance. A final processing integrates the extracted contours of the three chromatic components, generating the so-called integrated contours image
