    Full Text Available Bryn Fosburgh, vice presidente di Trimble e membro del comitato esecutivo della società, fornisce ai lettori di GEOmedia la sua visione del ruolo del topografo (e dunque del geometra, in Italia al giorno d’oggi.Come cambia il suo ruolo in questo contesto? Secondo Fosburgh il topografo è diventato un professionista della gestione, interpretazione, analisi e rappresentazione dei dati geospaziali; il suo nuovo ruolo dev’essere quello di guida per tutti gli utenti che hanno a che fare con questo tipo di dati. The Role of the Surveyor Yesterday, Today and TomorrowOver the past 50 years, advances in technology have increased the efficiency of the surveying profession, particularly in meas-urement  and  data  collection.  However,  the  new  technolo-gies—coupled with the decreasing population of professional surveyors worldwide—mandate that the surveyor’s role must and will change to managing, interpreting, analyzing and por-traying geomatics data. The surveyor must guide geospatial data consumers in a variety of related disciplines on how data is collected and used while maintaining a high level of data integrity.

    Full Text Available L’opera di pianificazione del paesaggio non può che passare attraverso la pianificazione delle componenti fisiche del territorio che, oltre agli indubitabili significati ed obiettivi funzionali, sono anche gli elementi costitutivi del paesaggio perché rappresentano le componenti percepibili del territorio medesimo; cosicché la pianificazione paesistica viene ad essere ad un tempo la diretta conseguenza e l’alta motivazione di quella urbanistico-territoriale conferendole motivi, fini e valori elevati.E le infrastrutture sono, come detto, le componenti fisiche primarie dell’antropizzazione del territorio sia in quanto tali, sia in quanto fattore per eccellenza di eventi generanti componenti fisiche.

    Full Text Available L’articolo riguarda un gruppo di sette codici che tramanda il testo del Lucullus di Cicerone e che appartiene al ramo della tradizione discendente dal manoscritto Wien, Österreichische Nationalbibliothek 189. I sette manoscritti costituiscono uno stadio della tradizione caratterizzato dalla presenza di tre lacune testuali. Sulla base di alcuni elementi paleografici e della presenza di una glossa riportata a margine del testo di uno di essi, El Escorial, V.III.6 (Scor4, e inglobata all’interno del testo degli altri sei, è possibile individuare in Scor4 il capostipite di questo gruppo della tradizione. Lo studio si occupa inoltre di fare chiarezza sui rapporti che intercorrono tra i sei discendenti di Scor4. The article focuses on a group of seven codices which carry the text of Cicero’s Lucullus. This group belongs to the branch of the tradition descending from the manuscript Wien, Österreichische Nationalbibliothek 189. The seven manuscripts represent a step of the tradition marked by the presence of some textual lacunas. I start from some paleographic elements and from the presence of a gloss on text’s margin of one of them, El Escorial, V.III.6 (Scor4. The gloss has been then incorporated in the text of the other six manuscripts and I assume that Scor4 is the founder of this group of tradition. Furthermore, this article aims to clarify the relations between the six descendants of Scor4.

    Full Text Available In questo lavoro analizziamo la nuova geografia del sistema bancario italiano che si è determinata in seguito al processo di integrazione delle strutture bancarie negli ultimi anni. L’analisi dell’evoluzione del sistema bancario si basa sul concetto di distanza. In particolare, non facciamo soltanto riferimento alla distanza tradizionale tra banca e clienti, che è la distanza operativa, ma anche alla distanza tra centri decisionali delle banche e i sistemi locali. L’oggetto del saggio riguarda gli effetti che la distanza (o prossimità funzionale determina sulla performance delle banche in termini di allocazione del credito, sull’efficienza e sulla profittabilità. Le nostre stime econometriche provano che la prossimità funzionale ha effetti territoriali asimmetrici sulla performance delle banche. I suoi effetti benefici sono statisticamente evidenti per le regioni meridionali meno sviluppate, mentre non sono significativamente rilevanti per le regioni più sviluppate del Centro-Nord dell’Italia.   In this paper we analyze the new geography of the Italian banking system that has arisen after the integration of banking structures in recent years. The analysis of the evolution of the banking system is based on the concept of distance. In particular, we do not only refer to the traditional distance between banks and customers, which is the operating distance, but also to  the distance between the centers of decision-making banks and local systems. The subject of the essay is about the effects that the distance (or proximity function determines on the performance of banks in terms of credit allocation, on efficiency and on profitability. Our econometric estimates show that the functional proximity has asymmetric territorial effect on the performance of banks. Its beneficial effects are statistically obvious to the less developed southern regions, while they are not significantly relevant to the more developed regions of central and

    delle principali lesioni interne con adeguata e istantanea pianificazione del trattamento chirurgico d'emergenza e/o rianimativo di supporto. Scopo del presente lavoro e' quello di illustrare il ruolo dell'esame TC nel documentare le molteplici e complesse lesioni pleuropolmonari, cardiovasali e della parete toracica, la cui compromissione si manifesta con semeiologia specifica e acuta del tutto diversa da quella della traumatologia toracica classica. Negli ultimi 4 anni sono stati osservati presso il pronto soccorso dell'Ospedale Loreto Mare di Napoli 76 casi di ferite d'arma da fuoco, di cui 26 con interessamento toracico: 25 maschi e una femmina (eta' media 32 anni, compresa tra 17 e 48 anni). Tutti i pazienti sono stati sottoposti a TC d'urgenza del torace con iniezione endovenosa di mdc e con tecnica angio-TC e in presenza del medico rianimatore con monitoraggio delle funzioni vitali e dello stato di shock. In 4 casi e' stato completato con studio TC dell'addome e pelvi per la presenza di lesioni associate toraco-addominali e in 3 casi con TC del cranio per lesioni encefaliche da proiettile. Il radiogramma del torace consente di documentare i danni maggiori toraco-polmonari d'arma da fuoco, anche se non permette la valutazione precisa delle lesioni cardiache e dei grandi vasi e dei pneumotoraci minimali. L'associazione di alterazioni traumatiche cranio-addominali concomitanti indirizza l'approccio diagnostico verso una metodica di primo livello come la TC, in grado di fornire con un unico esame il giudizio immediato sul grado di compromissione, panoramicita' e gravita' delle lesioni da arma da fuoco polmonari e extratoraciche. Cio' consente di instaurare la terapia tempestiva e mirata, sia essa chirurgica o di supporto rianimativo, evitando ritardi diagnostici e di gestione terapeutica sicuramente dannosi per la sopravvivenza del paziente.

    Full Text Available I sistemi di contabilità nazionale in base alla metodologia SEC sono soliti comportarsi in modo da garantire l'impossibilità pratica di effettuare qualsiasi assegnazione significativa di servizi bancari imputati tra i singoli rami di attività economica.  Il presente lavoro mostra come questo vieta l'analisi strutturale del ruolo del credito nel sistema di interdipendenze. . L'analisi mette in evidenza la duplice natura del credito come contenuti a valore aggiunto altamente intermedio e alto. È in grado di influenzare forte su i costi di produzione degli altri rami, senza essere influenzato da loro. Queste proprietà conferiscono al settore bancario un potenziale molto elevato per l'inflazione.National accounts systems based on the SEC methodology are usually thought to comport the practical impossibility of carrying out any meaningful allocation of imputed bank services among the single branches of economic activity. As a consequence, the total value of the net interest earned by the credit system as a whole is considered as a cost entry and a negative component of added value in an ad-hoc additional industry, to be aggregated to the main credit one in the typical input-output analysis. The present work shows how this prohibits the structural analysis of the role of credit in the system of interdependencies. A method of is proposed in which imputed services of credit are distributed by branches, on the basis of existing statistics, proving valuable in assessing the significance of certain quantities of national accounts, such as operating results. The analysis highlights the dual nature of credit as highly intermediate and high value-added content. It is able to strongly influence the production costs of the other branches, without being influenced by them. These properties give the banking industry a very high potential for inflation. JEL: E51, G21

    Agenda 21 is more and more often mentioned in debates and meetings dealing with environment, economy and development. How to actually make the aims enunciated in what is to be considered the next century programmatic document effective is, on the contrary, hardly outlined. The aim of this article is to help in making interaction between Agenda 21 and product reality more tangible and evident, specifically as far as composting is concerned. After an analytical description of the document, the points of contact between Agenda 21 and composting are identified: each one is highlighted through a rich bibliography. [Italian] L'Agenda 21 e' sempre piu' spesso ricordata all'interno dei dibattiti e degli incontri che trattano d'ambiente, economia e sviluppo. I modi attraverso i quali contestualizzare in pratica gli obiettivi enunciati in quello che va considerato come il documento programmatico del prossimo secolo sono invece spesso solo tratteggiati. Quest'articolo vuole essere percio' un contributo per rendere piu' tangibile e visibile l'interazione esistente tra l'Agenda 21 e la realta' produttiva; nel caso specifico il compostaggio. Dopo una descrizione analitica del documento, sono individuati in modo formale i punti di contatto tra gli obiettivi dell'Agenda 21 ed il compostaggio: ciascuno di loro e' messo in evidenza facendo riferimento ad un'ampia bibliografia.

    Paola Catenaccio

    2012-10-01

    Full Text Available This paper addresses the topic of rewriting in journalistic discourse by examining the typical textual features of the press release, one of the most commonly used journalistic sources. Journalism has long being recognised as being based on reproductive writing practices (Jakobs 2003, as it consists, as Bell (1991: 41 puts it, “of previously composed text reworked into text news”. In this process of rewriting, a key role is played by sources. While their use (and occasional manipulation on the part of journalists has been variously explored in the literature, less has been done to investigate the textual features of documents specifically designed to serve as sources, most notably press releases. The paper provides a description of the characterising features of the genre of the press release, highlighting the essentially “preformulated” nature (Jacobs 1999 of these documents, i.e. the fact that their formal traits, as well as the structuring of their content, are strategically designed to facilitate reproduction. The paper concludes that while the re-use of textual material from sources is a crucial aspect of journalistic text production, care should be taken to distinguish between rewriting and uncritical textual reproduction: although recourse to the latter has been growing exponentially over the last decade due to an increasing shortening of news production cycles that has turned journalists into “processors rather than generators of news” (Lewis et al. 2008: 27 under constant pressure to continuously “churn out” (Davis 2008 stories, a renewed attention to rewriting as a key component of journalistic text production practices should be encouraged.

    Full Text Available Diagnosis of H. pylori infection: the role of gastroenterologist Helicobacter pylori (H. pylori infection can be diagnosed by invasive techniques requiring endoscopy and biopsy (histological examination, rapid urease test, culture and by non invasive techniques (serology, urea breath test, detection of H. pylori antigen stool specimen.At present, no single test can be absolutely relied upon to detect colonization by H. pylori and a combination of two tests is recommended if feasible.Nevertheless, in routine dayto- day clinical practice H. pylori diagnosis is often by a single test and consequently the choice of the more suitable test is even more important. Choosing among them is not easy, and several issues need to be considered, such as the clinical situation, (i.e. present symptoms and past medical history, age of patients, if it is first diagnosis or follow-up after treatment.., sensitivity and specificity of the test, the cost-effectiveness of the testing strategy, the availability of the test, the local expertise . Since the “Ideal test” is not relied, the gastroenterologist or clinician as well, has the important role of deciding which test to employ. A good knowledge of advantages and vantages of each test is so necessary to make the best choose as possible.

    2017-04-01

    Full Text Available This paper aims to investigate the significance of mood for a philosophical approach to emotion. Are moods problematic because they constrain us in an affective cage? Or do they rather give us access to the world? The starting point for this investigation is the work of Martin Heidegger: I analyze what he defines as vorweltlich (what comes before meaning arguing that this term refers to the emotional dimension of human existence, in particular, to mood, or, in Heideggerian terms, Stimmung. Human existence is not just a neutral being-there but a being-affected, a being-in-a-mood. I then move on to consider the role of mood in relation to the concept of transcendence, providing an analysis of two main source of inspiration in Heidegger’s thought: Augustine and Aristotle. This allows us to distinguish three aspects of Stimmung: Stimmung as openness to the world, Stimmung as teleological movement, and Stimmung as event of ontological difference. In the final section, I discuss the contribution of these aspects of Heidegger’s thought to the contemporary debate on emotions.

L’articolo, a partire da queste prime indicazioni, affronta, attraverso l’analisi della rivista ufficiale dell’OIM «Mouseion»,  il tema dello sviluppo delle attività sociali e educative promosse dall’Office e declinate nei principali paesi membri della Società delle Nazioni fino al 1939, anno in cui si sarebbe dovuto svolgere un convegno internazionale sul tema, i cui risultati avrebbero dovuto costituire il terzo volume degli atti di Muséographie. Il convegno, di cui vengono qui riferiti proposte e programmi, non venne mai realizzato a causa dello scoppio della seconda guerra mondiale.   In 1927, the committee of experts convened to study the program of the Office International des Musées (OIM, established the previous year, had adopted a number of resolutions relating to the organization of the institution, cataloging and social role of the modern museum was increasingly called upon to perform. The paper, based on these early indications, addresses through the analysis of the official magazine «Mouseion» the issue of the development of educational and social activities promoted by the OIM and declined in the major member countries of the League of Nations until 1939, the year in which would have to play an international conference on whose acts would have to be the third volume of Muséographie. The conference, which we outline here the proposals and programs, was never realized due to the outbreak of the World War II.

    Full Text Available Riassunto - L’Autore ripercorre in chiave critica l’evoluzione delle politiche legislative in materia di lavoro, alla luce dell’attuale fase di crisi economico finanziaria. Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il proprio tradizionale ruolo di disciplina di tutela della persona.   Abstract - The author analyzes, with a critically oriented approach, the development of the employment law, in the light of the current economic and financial crisis. In examining the main regulatory measures implemented since the beginning of the century, the author highlights the methodological choices and the elements of continuity that unite the various measures, focusing them in a hard research of a point of balance between flexibility and security. The discussion concludes with some questions about the last lines of the reform of the labor market and with the hope that, even in the face of compelling reasons of economy, labor law can continue to play its traditional role of governing the protection of person.

    The new environmental regulations in Europe require higher standards for design and management of new landfills. Municipal solid wastes (MSW) have to be pretreated before land filling, in order to enable strong reduction of landfill emissions and environmental impact. The paper briefly describes the role of new landfills in solid waste management and the influence of some measures on the reduction of emissions and environmental impact. [Italian] In base alle nuove Direttive italiane e comunitarie, la discarica controllata e' destinata ad avere anche in futuro un ruolo di primo piano nella gestione dei rifiuti solidi urbani. In particolare, saranno destinati a smaltimento in discarica rifiuti pretrattati che garantiscano limitata putrescibilita' e minore impatto ambientale della discarica.

    1999-01-01

    Full Text Available El presente trabajo se propone reflexionar sobre las reformas de los sistemas de salud y de políticas sociales en el marco de las así llamadas reformas del Estado. Com esta finalidad, se busca como punto de partida condensar distintas visiones explicativas de la crisis del Estado de Bienestar, presentes en la bibliografía produzida en la década de los 90. En el corazón de la crisis, las políticas sociales se encuentran profundamente cuestionadas. Lo que pretendemos mostrar es que este argumento posee una función específica, que es la de introducir mudanzas de carácter neoliberal en la política económica y para las cuales los instrumentos económicos utilizados van a generar la abstención del Estado en el plano social, la desregulación de las economías nacionales en favor del libre mercado y, fundamentalmente, el papel sobredimensionado del mercado financiero internacional. En este contexto, son analizadas las reformas de la seguridad social y de los sistemas de salud. La última parte del trabajo tuvo por objetivo enfrentar las dificultades que las políticas sociales presentan en el contexto actual, trayendo al centro del debate un mapeamiento de las alternativas posibles para el desarrollo de las políticas sociales y de salud.

    Carmichael, H.

    1953-01-01

    A torsional-type analytical balance designed to arrive at its equilibrium point more quickly than previous balances is described. In order to prevent external heat sources creating air currents inside the balance casing that would reiard the attainment of equilibrium conditions, a relatively thick casing shaped as an inverted U is placed over the load support arms and the balance beam. This casing is of a metal of good thernnal conductivity characteristics, such as copper or aluminum, in order that heat applied to one portion of the balance is quickly conducted to all other sensitive areas, thus effectively preventing the fornnation of air currents caused by unequal heating of the balance.

    During last years, energy crops have been envisaged as an interesting alternative to biomass residues utilization as renewable energy source. In this work, main parameters used in calculating the energy balance of an energy crop are analyzed. The approach consists of determining energy equivalents for the different inputs and outputs of the process, thus obtaining energy ratios of the system, useful to determine if the energy balance is positive, that is, if the system generates energy. Energy costs for inputs and assessment approaches for energy crop yields (output) are provided. Finally, as a way of illustration, energy balances of some representative energy crops are shown.

  16. "Translation does not often demand genius": George Eliot e il ruolo del traduttore vittoriano

    Directory of Open Access Journals (Sweden)

    Michela Marroni

    2016-01-01

    Full Text Available George Eliot’s formative years were characterised by her intense activity as a translator which she carried out with methodological scrupulousness and profound sense of responsibility. In her ambition to make a name for herself in the English cultural world she understood, from a very early age, that translation would be the best means of expanding her knowledge while measuring herself against original texts that had made an important impact on European culture. Although Eliot was proficient in several modern and ancient languages (namely, German, French, Italian and Spanish, Latin, Greek and Hebrew, most of her translations were from German. It was with her translation of Strauss’s Das Leben Jesu that she proved her skill as a translator. Through this work her name also became familiar in Victorian theological debates. No less important was her translation of Feuerbach’s Das Wesen Christentums which, in many respects, led to her acceptance into the most advanced literary and philosophical circles in London. On the strength of this, in 1855, Eliot published the essay Translations and Translators which she wrote from her point of view as an affirmed journalist who was perhaps already contemplating the idea of becoming a novelist. The essay reveals both Eliot’s acute awareness of translation as a demanding work and of the role of the translator as a mediator between different linguistic and cultural realities. By indicating Germany as an example to follow, since in that nation the great poets and novelists translated the English classics into German, Eliot bluntly declared that the translator must work with a sense of responsibility and moral commitment and always aim for perfection.

  17. Mostrare l’identità. Il ruolo sociale degli emblemi alle origini del processo di individualizzazione

    Directory of Open Access Journals (Sweden)

    Lorenzo Grifone Baglioni

    2013-11-01

    Full Text Available The use of the emblems spreads within the cities of Europe in the first centuries after the Year 1000: the paper shows how this social phenomenon is related to the beginning of the individualization process. The signaletic and the symbolic practices related to the use of the emblems develop in parallel with the construction of the personal identity and the structuring of the social interdependence. With the emergence of both Court society and scientific sensitivity, the rapid araldic transformation of the emblems gives to the European ruling class the definitive monopoly of this extralinguistic code, erasing his early democratic meaning of personal autonomy expression.

  11. Mass balance evolution of Martial Este Glacier, Tierra del Fuego (Argentina for the period 1960–2099

    Directory of Open Access Journals (Sweden)

    M. Buttstädt

    2009-12-01

    Full Text Available The Martial Este Glacier in southern Tierra del Fuego was studied in order to estimate the surface mass balance from 1960 until 2099. For this reason a degree-day model was calibrated. Air temperature and precipitation data obtained from 3 weather stations as well as glaciological measurements were applied. The model was driven using a vertical air temperature gradient of 0.69 K/100 m, a degree-day factor for snow of 4.7 mm w.e. K−1 day−1, a degree-day factor for ice of 9.4 mm w.e. K−1 day−1 and a precipitation gradient of 22%/100 m. For the purpose of surface mass balance reconstruction for the time period 1960 until 2006 a winter vertical air temperature gradient of 0.57 K/100 m and a summer vertical air temperature gradient of 0.71 K/100 m were added as well as a digital terrain model. The key finding is an almost continuous negative mass balance of −772 mm w.e. a−1 throughout this period. While the calculation of the mass balance for the period 1960–2006 is based on instrumental records, the mass balance for the years 2007 until 2099 was estimated based on the IPCC SRES A2-scenario. To accomplish this estimation, the dataset of the global climate model HadCM3 was statistically downscaled to fit local conditions at Martial Este Glacier. Subsequently, the downscaled air temperature and precipitation were applied to a volume-area scaling glacier change model. Findings reveal an enduring deglaciation resulting in a surface area reduction of nearly 93% until 2099. This implicates that the Martial Este Glacier might be melted off at the beginning of the 22nd century.

    Full Text Available The enhancement of public real estate property is a very important issue at national and international level. For this purpose, the Italian public administration promotes many policies that are oriented to simplify patrimonial and planning procedures. Recently, new enhancement forms of public real-estate asset took place. Self-organized communities started to promote profit and no profit activities in unused public property. The aim of the paper is to analyse the main conditions to create new economic and social value by bottom up enhancement processes in Italian public real-estate assets. In particular, two hypothesis have been evaluated: the first one conceives the social capital as a premise to start these activities; the second one concerns the use of specific public policies as a tool to support bottom up processes. Throughout the multivariate statistics, have been analyzed fifty cases studies and three clusters emerged, confirming the initial theory of the research. Social capital is essential for the beginning of bottom-up processes to enhance public property. Nevertheless, where social capital is lacking, public policies can be a relevant alternative to support local bottom up activities.

    2012-12-01

    Full Text Available In a traditional Catholic country like Italy, the job of school teacher seems to be tailored just for women, in order to preserve quietly both roles of mother and working person, in the imagery of people who don’t work in the school world at least. This happens because the school has always been the second space of traditional display regarding gender differences, and the only one recognised as such by society, after the family. There’s no place like school where Italian women have been free to exhibit and make the most of their own relational competencies, even their sex difference, getting the same payment reserved for men but anyway lower than payments existing in other service sectors. Italy is the country where the family-school pair has assumed a legendary status for decades, with the woman usually seen as a link between these two environments; and maybe that’s exactly the reason why the school has become the stage where each and every metamorphosis of family is set up and the female presence gets its identity as biological and cultural reproductive subject. As long as teaching is that particular cognitive work in which the knowledge is hoarded to wield a lower power, women have been reduced to technical roles of teachers, so to be excluded from the spaces reserved to higher power: economy and politics. Maternalistic and consumerist structures typical of the last times led this subordination to a crisis in Italy too, but with no creation of a good alternative model. When the so-called First Republic (that was a kind of symbolic Father-State crashed down, the female model of cultural transmission broke up at the same time. In order to understand this trend, and perhaps to reverse it, the feminisation of teaching should be considered as a political question, and no longer as a treasure to be protected or defended. The same target regards the public school too.

    Full Text Available This article aims to analyze the relations between the trial of Adolf Eichmann and the Israeli national identity. It analyzes a trial which has its roots in the ius gentium and continues until the reappropriation of the memory of the Holocaust by Israel. The trial of Nazi criminal represents the moment when the Jewish state integrates his national experience to the memory of the destruction of European Jewry during the Second World War. Through the trials against Eichmann and its consequences on the Israeli public opinion, Ben Gurion strove for a nationalist rewriting of the Holocaust. The role of justice and law is central to the development of the national identity of Israel, providing a renewed civil identity that makes Israel the ‘guardian’ of memory and shifting the focus from the classic themes of Zionism.

    2009-01-01

    RIASSUNTO Introduzione I parametri di pressione arteriosa, sistolica (PAS) o diastolica (PAD) hanno costituito I’oggetto di numerosi studi, alcuni dei quali stabiliscono un’associazione tra I’aumnto di tali parametri e la mortalità, in particolare alle età medie. I fattori di rischio di ipertensione più frequentemente studiati sono il consumo di alcol, il fumo e I’origine etnica in riferimento sia alle differenze genetiche che nella condotta alimentare, mentre i fattori di origine professionale sono stati presi in considerazione più raramente e in maniera poco approfondita, inoltre sono state riferite notevoli differenze nelle pressioni arteriose medie di individui che svolgono professioni diverse. Sembra infatti che i “colletti blu” siano più a rischio dei “colletti bianchi”. Obiettivi Il nostro scopo è valutare se determinati rischi o vincoli connessi con l’attività professionale o determinati stili di vita rappresentano un fattore di rischio per l’ipertensione arteriosa in considerazioni dell’aumentare dell’età. Elementi specifici che rendano conto di questa relazione non sono stati ancora completamente chiariti e soprattutto i dati sulla popolazione italiana sono molto limitati. Metodi La metodologia di ricerca utilizzata è stata quella dell’indagine francese ESTEV (Derriennic, Touranchet, Volkoff) - VISAT (Marquie, Janson), studio epidemiologico longitudinale su oltre 23000 lavoratori attivata in Francia nel 1990 al fine di indagare gli effetti a lungo termine delle condizioni di lavoro, riferite all’intera vita professionale, sia sull’invecchiamento sia sulla salute dei lavoratori. Analoga indagine è stata avviata in Italia, nel 2000, in 6 Regioni, prendendo in esame i lavoratori dipendenti di diversi settori produttivi appartenenti a 5 coorti di età: da 32 a 52 anni con intervallo di 5 anni.

    Full Text Available Il paesaggio è un’entità spaziale complessa, nella quale troviamo registrate, sedimentate nel tempo, le trasformazioni di genere naturale e culturale, espresse con un linguaggio universalmente comprensibile in un testo unico e fragile. A questa concezione matura del paesaggio si può riferire il suo riconoscimento come indicatore di sintesi dello stato dell’ambiente, che l’ex Agenzia nazionale per la protezione dell’ambiente proponeva sul finire degli anni Novanta, indicando pertanto una possibile via, non semplice, né esaustiva, ma chiara e praticabile, per l’analisi e il progetto della sostenibilità dello sviluppo territoriale. La stessa definizione olistica che la Convenzione europea attribuisce al paesaggio costituisce una conferma ed un rafforzamento del suo significato quale esito primario delle modalità di sviluppo territoriale e pertanto della sua valenza di termine di valutazione delle relative condizioni di sostenibilità.

    Full Text Available La città sotterranea è un elemento fondamentale nella struttura urbana. Soprattutto nelle grandi città essa assume connotazioni rilevanti nella pianificazione urbana in considerazione del fatto che rappresenta una risorsa e il suo impiego può incidere significativamente sull’efficienza del sistema urbano. Alcune città, a causa soprattutto della rigidità del clima, hanno progettato città sotterranee di grande complessità funzionale; esempi significativi sono Montreal, Toronto e altre città del Nord America. In Europa occidentale le realizzazioni associabili al concetto di città sotterranea sono più limitate e sono relative soprattutto alla realizzazione di infrastrutture per la mobilità urbana, come le reti metropolitane, i passanti ferroviari, i tunnel stradali e i parcheggi sotterranei. La funzione primaria di questi spazi è la riduzione e lo spostamento dalla superficie di quote di traffico e la trasformazione di ampie parti della città in aree verdi o in aree a maggiore qualità ambientale. In ogni modo è possibile sostenere che l’uso degli spazi sotterranei è ormai entrato a far parte della vita delle città moderne. L’articolo analizza alcuni dei fattori principali nella costruzione di questi spazi urbani; i costi e i benefici dell’uso di spazi sotterranei sono messi in relazione con gli aspetti psicologici e con la costruzione di modelli per la previsione dei percorsi degli utenti. La seconda parte dell’articolo mostra alcuni casi studio evidenziando le diverse necessità che hanno spinto e hanno guidato verso la scelta degli spazi sotterranei; una analisi più dettagliata è svolta sul caso di Montreal, che può essere considerato archetipo della citta sotterranea.

    Full Text Available Los suelos con capa freática poco profunda poseen mayor probabilidad de ser afectados por anegamiento. La predicción de la oscilación temporal del nivel freático constituye una importante herramienta para valorar el riesgo de ocurrencia de tal proceso. El objetivo de este trabajo es presentar los fundamentos teóricos, la estructura operativa y la capacidad predictiva del modelo de simulación del balance hídrico Freat.1. El modelo se fundamenta en el cálculo de la transferencia de agua entre la atmósfera, el perfil del suelo, la vegetación y la capa freática. Los procesos de transferencia simulados son: escurrimiento superficial saliente, ascenso del nivel freático por efecto de la lluvia neta y del escurrimiento subterráneo entrante y descenso del nivel freático por efectos del escurrimiento subterráneo saliente, evaporación, ascenso capilar desde la capa freática y transpiración de la vegetación. Se evalúan los resultados de su aplicación en un Haplustol udorténtico y en un Natralbol típico ambos con freática oscilando a menos de tres metros de profundidad. El error de predicción estimado como la raíz del error cuadrático medio entre registros freáticos observados y simulados es menor de 15 cm para ambos suelos. Se concluye que el modelo resulta apropiado para predecir oscilaciones temporales de capa freática y evaluar el riesgo de inundación por anegamiento en suelos con capa freática cercana a la superficie.Soils with shallow water table have greater probability of being affected by waterlogging.

    One of the tendencies in many power reactors has been to modify some operation conditions, in order to increasing the electricity generation. The Laguna Verde Nuclear power plant (CNLV) it has not been the exception and in the recent past an increment of 5% was made in the original nominal thermal power. In the face of the possibility of carrying out more modifications, a study was made in the one that one simulates an eventual increment of the power of the reactor in 15% of the original value. With this increment one carries out the balance of the plant and the thermodynamic properties were determined. With this purpose it was developed a computer tool to calculate the thermodynamic properties of the plant in several points of the power cycle, as well as to carry out energy and mass balances to determine the flows in the different extractions of steam of the turbines. The program is compared with the results to 100% and 105% of increase of power obtaining good results, for what it is concluded that the extrapolation to 115% of power increase is acceptable.

    Full Text Available Il tema affrontato concerne il ruolo dell’informazione economica nell’ambito dei mercati immobiliari. Si parte dai riferimenti della letteratura economica sulla teoria dell’informazione per individuare le informazioni economiche rilevanti per monitorare e analizzare il mercato immobiliare, sia dal punto di vista macroeconomico sia da quello microeconomico. In entrambi gli ambiti non è sufficiente soltanto l’informazione sul prezzo, ma su numerose altre variabili. Sull’importanza dell’informazione economica è utile l’indicatore della trasparenza dei mercati immobiliari elaborato da Jones Lang Lasalle costruito anche sulla base di una valutazione sulla qualità e quantità di informazione economica disponibile sugli oggetti scambiati sui fenomeni che caratterizzano il mercato immobiliare. Si analizza infine lo stato dell’informazione in Italia sul mercato immobiliare ed il ruolo e l’offerta informativa istituzionale resa dall’Osservatorio del mercato immobiliare dell’Agenzia del Territorio.

    Full Text Available Enhancing cultural heritage in mountain regions is a crosscutting topic: environmental protection, social and cultural promotion and economic development have the same relevance and require to find a durable balance among them. Alpine areas bear geographic and permanent disadvantages. These include physical factors, such as morphology, climate, hydro-geologic risk, and human geography weaknesses, such as the low density, which prevents any arising of agglomeration economies, the isolation of local communities and the limited accessibility. Moreover, the opportunities for strengthen the territorial development by cultural heritage are not always consensual. Conflicts between preservation of tangible and intangible cultural values for local communities and the heritage marketing according to consumers’ needs often arise. This paper proposes an integrated approach able to consider the spatial features of each dimension of the problem and to support the definition of future development strategies. In particular, the proposed approach will be tested on a real case related to the system of historical castles located in the Valle d’Aosta Region in the North of Italy.

    Full Text Available El fin del periodo autárquico dejaba las comarcas mineras asturianas en una difícil situación. Las estructuras productivas estaban obsoletas, lo que dificultaba la competitividad de su carbón y acero en un nuevo contexto de mercado libre y abierto. Pero más acuciante aún era lo que se refería a su tejido urbano y social. En los años sesenta del siglo XX muchos lugares carecían aún de infraestructuras básicas como carreteras, luz o agua, y todas las cuencas presentaban escasos equipamientos educativos, deportivos, y culturales. El Plan de Mejora del Hábitat Minero intentó corregir estos desequilibrios antes de abordar la reestructuración de sus sectores industriales principales.The autarkic period end left the Asturian mining regions in a difficult situation. Production structures were obsolete, leaving little room to the competitiveness of its coal and steel in a new context of free and open trade. But even more pressing it was regarding its urban and social fabric. In the Sixties of the twentieth century many places still lacked basic infrastructures like roads, electricity or water, and all the basins had little education facilities, sports, and libraries. The Mining Habitat Improvement Plan of will try to correct these imbalances before addressing the restructuring of its main industrial sectors.

    Full Text Available The work tackles the development of a procedure to evaluate the energetic efficiency in linear infrastructures from a constructive point of view. This procedure allows to calculate the balance of energy along the different phases of life cycle analysis in infrastructure, such as construction, operation - maintenance and deconstruction, both in general and independent terms. Being the target the quantification of energy in the infrastructure, the procedure allows the efficient management of its energy consumption and other environmental impacts, throughout the selection of alternatives and the mitigation or compensation of the balance between its different phases. This paper describes the developed methodology in the procedure, tested by means of a practical example case study, where the embodied energy of one of the functional units in which the motorway is divided (a straight two-way highway stretch is quantified in Jules. The individual amount of different phases is also quantified to establish a balance between them too

    El trabajo aborda el desarrollo de un procedimiento para la evaluación de la eficiencia energética en infraestructuras lineales desde el punto de vista constructivo. El procedimiento permite calcular, tanto globalmente como de forma independizada, el balance energético de las diferentes fases del ciclo de vida de la infraestructura: construcción, operación y desmantelamiento o deconstrucción. Siendo el objetivo la cuantificación de la energía de la infraestructura, el procedimiento permite gestionar eficazmente el consumo de energía y otros impactos ambientales mediante la selección de alternativas y la mitigación o compensación de los balances entre las diferentes fases. En el presente artículo se describe la metodología desarrollada, validándose mediante la aplicación a un caso práctico a modo de ejemplo, cuantificando en Julios la energía embebida en una de las unidades de cálculo o

    Full Text Available Este artículo analiza la transformación del estado nacional colombiano bajo el gobierno de Álvaro Uribe, centrándose en el Plan Colombia y los proyectos estatales que se desprenden de él, a fin de dar cuenta de la militarización estatal y la represión social asociada a ambos. Se argumenta que políticas de gobierno amparadas en dicho Plan tienen como objetivo la consolidación de un régimen de acumulación de mercado extractivo y especulativo que, aunque vinculado a un impulso hegemónico transnacional centrado en los Estados Unidos, también está íntimamente ligado a desarrollos locales y al conflicto interno de Colombia. Estas interacciones ofrecen una ilustración ejemplar de la reconfiguración a múltiples escalas de la política en la economía del mundo actual.This article analyzes the transformation of the Colombian national State under the government of Álvaro Uribe, focusing on Plan Colombia and the State projects that flow from it, in order to reflect on the militarization of state and the social repression associated with both. It is argued that government policies under the Plan are aimed at consolidating a regime of market accumulation and speculation that, while linked to a transnational hegemonic thrust emanating from the United States, is also closely linked to local developments and Colombia's internal conflict. These interactions provide an exemplary illustration of the reconfiguration at multiple levels of the world political economy today.

    Full Text Available La formazione rappresenta uno strumento basilare nella promozione della lingua e della cultura italiana. L’argomento è articolato e complesso perché abbraccia diverse questioni. Da un lato va sostenuto l’utilizzo di mezzi adeguati, come quello telematico, che favoriscono e facilitano la diffusione all’estero. Dall’altro la proposta didattica di università e scuole deve essere riorganizzata alla luce delle nuove esigenze formative. Il ruolo degli atenei italiani potrebbe diventare più incisivo se si adeguassero maggiormente agli standard esteri, in modo da favorire la circolazione di studenti anche verso e non soltanto dall’Italia. Per quanto riguarda, invece, il tipo di formazione da sostenere, va riqualificata quella umanistica e tradizionale, non perché rappresenti la cultura nella sua totalità ma perché costituisce un patrimonio che caratterizza il nostro paese e non deve andare perso. Abbiamo parlato di queste tematiche con il Professor Roberto Greci, Preside della Facoltà di Lettere e Filosofia dell’Università di Parma e Presidente del Consiglio scientifico e didattico del Consorzio Interuniversitario ICoN, Italian Culture On the Net.     The role of training in the promotion of Italian language and culture.

    Retrospective dosimetry requires measurement methods allowing the determination of Radon concentration in the past. One of the such methods is based on the direct measurement of 210Po implanted on the surface of objects, whose activity concentration (Bq/m2), is directly related to the cumulative exposure due to the concentration of 222Rn (Bq/m3) for long time. These determinations are possible taking into consideration the equilibrium between 210Po (T1/2 = 138.378 days) and its parent 210Pb (T1/2 = 22.3 years), being both radionuclides from the 222Rn progeny. In previous works about the determination of the conversion factor (ratio between the concentration of 210Po in objects and the retrospective 222Rn concentration in air), Corresponding equilibria between descendants were assumed. In this work, an experimental study about the equilibrium 210Pb - 210Po in glasses, which were previously exposed to some radon concentrations, has been performed. Two scenarios were studied: a place with, and another place without, continuous cumulative 222Rn concentration. Results were compared with those reached by theoretical calculations from the (Bateman) activity evolution equations. [Spanish] La dosimetría retrospectiva requiere métodos de medida que permitan la determinación de la concentración de radón en el pasado. Uno de estos métodos está basado en la medida directa del 210Po implantado sobre la superficie de objetos, cuya concentración de actividad (Bq/m2), está directamente relacionada con la exposición acumulativa debida a la concentración de 222Rn (Bq/m3) durante largos períodos de tiempo. Estas determinaciones son posibles gracias al equilibrio entre el 210Po (T1/2 = 138,378 días) y su progenitor, el 210Pb (T1/2 = 22,3 años), siendo ambos radionúclidos descendientes del 222Rn.

    Full Text Available Purpose: In this article we aim to identify and analyze a set of contingent and institutional variables that can potentially influence the knowledge and the adoption of the Balanced Scorecard (BSC in Portuguese public and private organizations. Design/methodology/approach: Hypotheses were tested using data obtained from a questionnaire sent to 591 public organizations and 549 private organizations in Portugal, with an overall response rate of 31.3%. Findings and Originality/value: The results indicate the association between BSC knowledge and the level of training of employees, and between BSC implementation and conducting training courses. On the other hand, we did not obtain empirical evidence regarding the possible relationship between the BSC implementation and the degree of internal communication, the use of external consultants, questions of "management fads" and the search for legitimacy. Originality/value: In the literature review we did not found bibliographic elements about the contingent and institutional factors that determine the BSC adoption in Portugal, a fact that allowed us to give this study an innovative approach. Moreover, the BSC situation in Portugal has been characterized, doing a comparative study with the results of studies conducted in other countries.Objeto: Este artículo tiene como objetivo identificar y analizar un conjunto de variables contingentes e institucionales que pueden potencialmente influir en el conocimiento e implementación del Cuadro de Mando Integral (CMI en las organizaciones portuguesas pertenecientes al sector público y privado.

Tutti saranno d'accordo che la risposta al puzzle sta nel fatto che le operazioni in conto corrente costituiscono ormai solo una piccola parte dei movimenti valutari lordi,  dominata di fattop da movimenti di capitali. Ciò che deve essere spiegato  allora è l'enorme volume di capitale netto totale che finanzia il deficit. Il presente lavoro considera questo paradosso, il ruolo del dollaro nel sistema monetario mondiale e le prospettive a medio e lungo termine per il sistema finanziario mondiale.The continuous and spectacular rise of the dollar on the global foreign exchange market, despite the equally spectacular current account deficit of the U.S. balance of payments, is something that no economist would have dreamed to be possible. Everyone will agree that the answer to the puzzle lies in the fact that the transactions in the current account now constitute only a small part of the gross currency movements, in fact dominated by capital movements. What needs to be explained then is the sheer volume of the total net capital that finances the deficit. The present work considers this paradox, the dollar’s role in the world monetary system and medium and long-term perspectives for the world financial system.JEL: E52, F31, E42,

    Il libro mostra come la gravitazione abbia un ruolo determinante nei fenomeni cosmici che più ci impressionano, da quelli relativamente vicini alla nostra esperienza (come la formazione delle stelle) a quelli meno intuibili (come la formazione dei buchi neri), alla struttura dell'Universo nel suo insieme. Oltre a spiegare, in modo qualitativo, concetti come la geometria dello spazio-tempo, la relatività del tempo e i coni di luce, l'autore formula un'ipotesi innovativa tendente a spiegare l'origine della gravitazione e con essa quella dei fenomeni circondati ancora da un alone di mistero: la materia oscura dell'Universo e il destino della materia alla fine del collasso gravitazionale.

El Balance Afectivo se refiere a las respuestas emocionales de la persona cuando hace juicios valorativos sobre su vida, y es el resultado de la consideración de las emociones tanto positivas como negativas experimentadas a lo largo de un período de tiempo determinado. Este estudio presenta las características de la Escala de Balance Afectivo (EBA (versión española de la escala de Afecto Positivo y Negativo de Warr et al., 1983 en una muestra española adulta obtenida de la población general. METODOLOGÍA: Participaron voluntariamente en este estudio 219 personas con edades comprendidas entre los 18 y 64 años (M= 30.54; dt= 10.79; 62.1% mujeres procedentes de diferentes contextos comunitarios. Los participantes respondieron 4 medidas sobre balance afectivo, competencia personal inespecífica, salud general y satisfacción vital en una única administración. RESULTADOS: Respecto a las propiedades psicométricas de la EBA, las subescalas de Afecto Positivo y Afecto Negativo muestran una elevada consistencia interna, con valores de alfa de Cronbach de 0.82 y 0.75 respectivamente. Sus elementos muestran un adecuado comportamiento que refleja su pertinencia y relevancia para la medida del Balance Afectivo. La estructura factorial arroja un modelo bifactorial perfectamente ajustado a la propuesta teórica. No obstante, dos ítems necesitarían ser reformulados. El análisis de la posible relación entre el afecto positivo y el afecto negativo realizado utilizando un modelo de ecuaciones estructurales apoya la estrecha relación inversa entre ambas dimensiones de la afectividad. La escala muestra una adecuada validez convergente con medidas de competencia personal inespecífica o global, de salud física y mental y de satisfacción vital.

El modelo general de evaluación de cada uno de los compartimentos y flujos es el balance hídrico. Los métodos desarrollados para calcular el balance hídrico de una región toman como base el enfoque de transferencia de masa o el de transferencia de energía. Este trabajo se planteó como objetivo calcular, comparar y evaluar tres aproximaciones en la estimación del balance hídrico regional espacialmente distribuido en cuencas sin datos de aforos. El modelamiento espacial de las variables hidrometeorológicas se efectuó en el sistema de información geográfica ArcView 3.2, y el modelamiento de los del escurrimiento se realizó con el sistema HEC versión 3.1.0. La primera aproximación está basada en el análisis de la información registrada en las estaciones meteorológicas disponibles, estimación puntual del balance hídrico mensual conforme al método de Thornthwaite y Mather y de polígonos de Thiessen; la segunda, en el cálculo y distribución de los parámetros para la aplicación del Método de Thornthwaite y Mather; finalmente la tercera aproximación se basó en el uso de la ecuación de FAO – Penman. Se escogió a la cuenca del lago de Cuitzeo como área de aplicación de los modelos. Destaca que mediante el resultado de la 3ª aproximación el volumen anual promedio de escurrimientos corresponde a 229.05 hm3. Dicho volumen es apenas 8.5 hm3 inferior al estimado como necesario para mantener 1 m de profundidad en la extensión del cuerpo de agua del lago de Cuitzeo.

    Introduzione – Nei pazienti con epatopatia cronica, l'ipertensione portale rappresenta la causa delle principali complicanze (sanguinamento da varici, ascite, encefalopatia epatica) che, insieme all’epatocarcinoma, costituiscono la causa più importante di ospedalizzazione e mortalità. Le metodiche gold-standard per la valutazione dell’ipertensione portale sono la misurazione del gradiente di pressione venosa epatica (HVPG) mediante cateterismo delle vene sovraepatiche e l’esofagogastroduodeno...

    RIASSUNTO. La terapia farmacologica nei pazienti con disturbo da uso di alcol riveste un ruolo centrale nel progetto terapeutico, altamente contestualizzato in un approccio multidisciplinare. Sebbene i trattamenti non farmacologici per la dipendenza da alcol risultino ben strutturati e in continua evoluzione, dal punto di vista medico le possibilità di intervento sono realmente ristrette, con poche molecole a disposizione approvate per il disturbo da uso di alcol: nello specifico, l'acamprostato, il naltrexone e, più recentemente, il nalmefene tra gli anticraving; il disulfiram tra gli avversivanti. Nuovi approcci sperimentali stanno cercando di ampliare tale gamma attraverso l'utilizzo di farmaci off-label. Evidenze scientifiche devono supportare l'indicazione terapeutica, quest'ultima deve dimostrarsi "cucita" sulle esigenze del paziente e sulle comorbilità presenti tenendo conto del profilo bio-psico-sociale individuale. Fondamentale risulta il follow-up per valutare la ritenzione in trattamento e il monitoraggio degli outcome alcologici.

The present research analyses the evolution in the role of women from end of 80’s till the last judgements by Italian Courts, where in the perpetrator, the co-perpetrator was for the first time found to be a woman.The essay on women and the local mafia seek to answer different questions from a wide range of academic disciplines and trace the portrait of women tied to organized crime in Italy and especially in Bari, where there are exclusive criminal organizations involving women. This evolution pulls back the code of silence and shines a light on the dark image of women entangled in organized crime, as a mediator, co-perpetrator, boss at the top of organised criminal group. The surprising first hand account of mafia women in Bari, reveal women in power, also in relation to the art. 416 bis of Italian criminal code.

    The aim of the present work is to assess the hydro-geological water balance of the soil and subsoil system. At the beginning, the natural groundwater recharge evaluated as the subtraction between the soil inflows (rainfall) and outflows (evapotranspiration, surface runoff) enable to determine the soil water balance. Then, in order to calculate the subsoil water balance, the withdrawals for different purposes have been estimated together with the inflows coming from other water bodies and the coastal outflows. This method has been applied through a GIS technique; in particular, after the data layers acquisition (climatic, topographic, geologic, land use, satellite images, etc.), the numerical calculation has been done and several thematic output maps have been obtained. The method has been applied to the whole Apulian region; in this work, only the results about Salento Peninsula have been reported. The results highlight a significant water resources deficit; this deficit is also confirmed by the deepening of groundwater piezometric heads and the increase of chlorine ions, measured, for more than 10 years, in some characteristic points located in the study area. [Italian] Scopo del presente lavoro e' valutare il bilancio idrogeologico mediante il bilancio di massa per il sistema rappresentato dal complesso suolo e sottosuolo.

Successivamente, per calcolare il bilancio di massa del sistema sottosuolo sono stati stimati gli emungimenti per i diversi usi, gli afflussi provenienti da altri corpi idrici sotterranei e gli efflussi a mare.

Estendere l’esperienza albanese agli altri Stati balcanici o quella dei Balcani all’Albania? Abstract   The protection of individual and collective freedom of religion and freedom of conscience, the regulation of state relations with religious communities in Albania, have found a solution in peculiar legal rules and traditions that in the history of the Albanian people have guaranteed the religious peace. Of great significance was the Albanian legal system resistance to accept the advice of the Venice Commission, Council of Europe and the EU that would rather prefer and have sought to impose the adoption of a single political-legal model for the Balkans, focused on a general law for the protection of religious freedom.Albanian model dates back to 1923, recognizes the cultural and religious pluralism of society and the opportunity for all religious communities to obtain civil legal personality, now allows cooperation agreements with the various religious communities. The rules put as guarantees of religious freedom those of the general law without any recourse to special rules. What happened was possible because of the plural nature of Balkan Islam which has allowed mutual respect and tolerance, and thanks to the secular and separatist nature of the Albanian state since its origins.State law likewise religious rules, determined by the Statutes that communities have been given themselves and their progressive transformation have played a role in education for coexistence which has allowed, in contrast to what happened in many Balkan countries, religious peace.The smaller denominations and cults have found, and find now, legal protection, and at present are five the creeds that have concluded agreements with the state and others may do so in the future. The success of the Albanian model warns against standardization policies, substantially octroyé, supported by international bodies end one size fits all legal model/pattern.

    Obiettivi: l’associazione fra stato socio-economico (SES ed attività fisica è poco indagata. Obiettivo del presente studio è quello di valutare la relazione tra attività fisica extra-scolastica di adolescenti scolarizzati e lo SES della famiglia di provenienza.

    Metodi: l’indagine ha previsto la somministrazione nel corso dell’anno scolastico 2002-2003 di un apposito questionario anonimo autocompilato, già validato in uno studio pilota, ad un campione di studenti delle scuole medie inferiori del Lazio (province di Roma, Frosinone e Latina.

    Risultati: hanno partecipato allo studio 1486 studenti di cui 756 maschi (50.9% e 730 femmine (49.1%. L’età dei partecipanti varia fra gli 11 ed i 15 anni (età mediana 12 anni. Il 72.7% degli studenti dichiara di svolgere attività fisica al di fuori della scuola. Il livello di istruzione dei genitori e la loro attività lavorativa sembrano avere un peso notevole sui determinanti dell’attività fisica negli studenti. Infatti, svolgono prevalentemente attività fisica extra-scolastica i figli di genitori manager/libero professionisti (OR = 3.29 e con un elevato livello educativo (OR = 10.38 per i figli di genitori laureati.

    Conclusioni: i risultati confermano quanto la situazione socio-economica delle famiglie sia in netta relazione con l’attività fisico-sportiva dei giovani. Tali risultati potranno essere utili per gli operatori scolastici e gli amministratori nell’ispirare e realizzare azioni volte a diminuire il divario esistente fra i giovani che hanno le possibilità economiche e svolgono attività sportiva extra-scolastica e quelli che, invece, appartenendo a famiglie svantaggiate, hanno minore accesso a tali attività.

Métodos: Los datos se recogieron mediante una encuesta enviada a 884 directivos miembros de equipos de dirección de 218 hospitales públicos en España. El índice de respuesta fue del 53,51%, con 473 cuestionarios útiles. Se realizó una validación métrica de las escalas usadas y un análisis del modelo con técnicas de ecuaciones estructurales. Resultados: Los directores más jóvenes y con menos antigüedad suelen hacer un mayor uso del cuadro de mando integral que del presupuesto. La diversidad en el equipo de dirección está relacionada con el empleo de diferentes técnicas de control de gestión. El uso del cuadro de mando integral se relaciona positivamente con la implantación de estrategias sanitarias centradas tanto en la mejora de la flexibilidad como en el control y la reducción del coste sanitario. Conclusiones: La adopción de sistemas de control de gestión no sólo es resultado de un proceso racional y de presiones institucionales, sino que también depende de las características de los individuos responsables de la toma de decisiones. El uso del cuadro de mando integral facilitará que los hospitales puedan implantar planes estratégicos con múltiples objetivos.Objective: To analyze the relationship between hospital managers' characteristics and the use of the balanced scorecard and the budget.

    Full Text Available The Balanced Scorecard (BSC, developed by Kaplan and Norton in 1992, responded to a need for consolidating the performance complexity of the organization and has been increasingly used since then. Among the advantages are the composition and visualization of performance measurements that reflect the company’s business strategy. The BSC summarizes and indicates in a single document, performance from four perspectives, financial, clients, internal processes and learning and growth. This study is important because the BSC is the first systematic attempt to develop a project for a performance evaluation process that focuses on company objectives, coordination of individual decisions and a basis for the organizational learning. Therefore, applicable literature was reviewed and a presentation was made on implementation of the BSC at Petrobras, an integrated state-owned company acting in exploration, production, refining, commercialization and transport of oil and derivatives in Brazil and abroad.El Balanced Scorecard (BSC, desarrollado por Kaplan y Norton en 1992, resultó de la necesidad de captar toda la complejidad del desempeño de la organización, y ha sido amplia y creciente su utilización en empresas y organizaciones.

Si bien este tipo de sistema ha sido abordado en la literatura bajo el título de sistemas de producción autoequilibrado, en donde el equilibrio se logra mediante la utilización de dos reglas básicas, creemos que estas reglas no son suficientes para lograr el autoequilibrio. Por lo cual incorporamos el concepto de zonas de enlace que facilita el equilibrado de la línea.

Although this type of system has been approached in the literature under the name of self-balanced production system, where the balance is achieved using two basic rules, we believe that these rules are not sufficient to achieve self-balance, so we have incorporated the concept of linkage zones that facilitate balancing the line. From the results obtained by simulation we conclude that the heuristic is efficient for this kind of production system.

    The present work is a continuation of the task: Modeling of the vapor cycle of Laguna Verde with the PEPSE code to conditions of thermal power licensed at present (2027 MWt) in which the modeling of the vapor cycle of the nuclear power plant of Laguna Verde was realized with PEPSE code (Performance Evaluation of Power System Efficiencies). Once reached the conditions of nominal operation of extended power increase, operating both units to 2371 MWt; after the tests phase of starting-up and operation is necessary to carry out a verification of the proposed design of the vapor cycle for the new operation conditions. All this, having in consideration that the vapor cycle designer only knows the detail of the prospective performance of the main turbine, for all the other components (for example pumps, heat inter changers, valves, reactor, humidity separators and re-heaters, condensers, etc.) makes generic suppositions based on engineering judgment. This way carries out the calculations of thermal balance to determine the guaranteed gross power. The purpose of the present work is to comment the detail of the validation carried out of the specific thermal balance (thermal kit) of the nuclear power plant, making use of the design characteristics of the different components that conform the vapor cycle.

    In the risk evaluation of uncontrolled biogas emissions from landfills, the process of natural attenuation in landfill covers assumes a very important role. The capacity of biogas oxidation in the cover soils seems to be the most important control to mitigate the biogas emission during the aftercare period when the biogas collection system might fail. In the present paper laboratory experiences on lab columns to study the biogas oxidation are discussed. [Italian] Nella valutazione del pericolo di emissioni incontrollate di biogas da una discarica, il processo dell'attenuazione naturale della copertura superficiale assume un ruolo molto importante. La capacita' di ossidazione del biogas nel terreno di copertura sembra rappresentare il controllo piu' importante nella mitigazione di fughe incontrollate di biogas, soprattutto nel lungo periodo quando la captazione del biogas perde efficienza. Nel presente lavoro si riportano alcune esperienze di laboratorio per valutare l'ossidazione di metano in diverse tipologie di copertura.

    Full Text Available En el transcurso de los últimos 15 años, los gobiernos de los Estados Unidos y Colombia han trabajado conjuntamente para luchar contra el problema de seguridad más importante que ha enfrentado el continente americano en las postrimerías del siglo XXI. Los grupos Narco terroristas colombianos se convirtieron en la principal amenaza para la seguridad nacional de los Estados Unidos en el hemisferio occidental; no sólo a causa de la producción de drogas y el tráfico de drogas, sino también de las actividades terroristas en contra de los intereses de los Estados Unidos en la región. El Plan Colombia fue una estrategia que tuvo como propósito principal establecer y garantizar un Estado que pudiera ejercer su verdadera autoridad y cumplir con sus obligaciones esenciales. De igual forma, este plan tuvo un componente militar con el fin de poner fin al comercio de drogas mediante la erradicación de cultivos ilícitos. Algunos objetivos del Plan Colombia como reducir el cultivo, procesamiento y distribución de narcóticos ilegales atacando el cultivo de coca no se cumplieron, además, durante estos años el fenómeno de la minería ilegal comenzó a prosperar y se convirtió en una importante fuente de ingresos para los grupos narcoterroristas colombianos. Dentro de los Principales logros se puede establecer que con esta estrategia el Estado Colombiano ha logrado la recuperación de su institucionalidad y la consolidación de la presencia del gobierno en todas las áreas del territorio nacional, así como la reestructuración del sistemas políticos y jurídicos, el fortalecimiento de su economía, la profesionalización de las Fuerzas Armadas y la posibilidad de iniciar un proceso de negociación con las Fuerzas Armadas Revolucionarias de Colombia (FARC y el Ejército de Liberación Nacional (ELN.

    Margarita Posso

    Full Text Available El objetivo de este estudio es valorar, en base a un análisis crítico y estructurado de la evidencia, si el tamizaje mamográfico de cáncer de mama en Perú es una intervención recomendable. El análisis se realizó utilizando los criterios propuestos por el sistema GRADE (Grading of Recommendations Assessment, Development and Evaluation. Se realizó una búsqueda de la literatura en Medline y en otras fuentes de información nacional (literatura gris. Para el desarrollo de la recomendación, a favor o en contra del tamizaje, se utilizó la mejor evidencia disponible sobre los beneficios, riesgos, costos y preferencias de la población. Los resultados incluyeron cinco revisiones sistemáticas (RS que evaluaron los riesgos y beneficios del tamizaje; dos evaluaciones económicas realizadas en Perú y un estudio que valoró indirectamente las preferencias de las mujeres peruanas. La calidad de la evidencia a partir de las RS fue moderada a favor del tamizaje en mujeres de 50 a 69 años. El balance entre riesgos y beneficios mostró una mayor probabilidad de sobrediagnóstico comparado con el beneficio en la reducción de la mortalidad. La estrategia más costo- efectiva fue la mamografía trienal. La percepción de barreras podría comprometer seriamente la participación de las mujeres. En conclusión, la recomendación a favor del tamizaje mamográfico en Perú es débil, más aun si se tienen en cuenta otras necesidades poblacionales más urgentes. En caso de llevarse a cabo, la estrategia de tamizaje más adecuada para la población peruana consistiría en realizar una mamografía trienal en mujeres de 50 a 69 años.

Mediante un análisis de la evolución de los flujos de capitales y del comercio, y de su impacto sobre el empleo y el nivel de los salarios en los sectores industriales y agrícolas, el autor revela los logros y los límites del modelo de integración del TLCAN. Concluye que aunque el TLCAN no puede ser la solución a todos los problemas socioeconómicos de México, lo que el acuerdo padece, a pesar de todo, es una "institucionalidad (social deficiente" que puede consolidarse por medio de reformas nacionales y supranacionales. A nivel nacional, el gobierno mexicano tiene que replantearse su estrategia de crecimiento dependiente de las exportaciones y dar prioridad a la reforma fiscal y a las inversiones en el sector de la educación y las infraestructuras. A nivel supranacional, el modelo del TLCAN debería mejorarse con el fin de subsanar sus carencias sociales, particularmente en los sectores de la inversión, la inmigración, la agricultura y las transferencias de recursos.

    2007-09-01

    Full Text Available Obiettivo di questo lavoro è quello di fornire le principali linee di orientamento teorico dell’approccio psicodinamico relative alla funzione del sogno. In tal senso ci si avvarrà della metapsicologia Freudiana, ma anche dei prestigiosi contributi sul carattere del sogno portati da Wilma Bucci. In particolare, si proporrà un parallelismo tra la metapsicologia e la teoria del Codice Multiplo. La teoria energetica di derivazione psicoanalitica mette in risalto alcuni punti cardine sul ruolo del sogno: 1 il sogno deriva dall’energia di un desiderio inconscio; 2 i sogni hanno la funzione di preservare il sonno; 3 la nozione di un censore che si attiva per distorcere e mascherare i contenuti latenti; 4 i contenuti manifesti hanno la funzione di nascondere il reale significato del sogno. Secondo la teoria del codice multiplo, il sogno ha un valore là dove fornisce l’accesso al significato emotivo che è stato dissociato, ma la funzione dell’elaborazione dell’informazione emotiva nel sogno è sovrapponibile a quella dell’elaborazione dell’informazione emotiva durante la veglia, in particolare per quanto riguarda il sonno REM.

    This document contains the Users Manual of Visual Balan V1.0, an updated version of Visual Balan V0.0 (Samper et al., 1997). Visual Balan V1.0 performs daily water balances in the soil, the unsaturated zone and the aquifer in a user-friendly environment which facilitates both the input data process and the postprocessing of results. The main inputs of the balance are rainfall and irrigation while the outputs are surface runoff, evapotranspiration, interception, inter flow and groundwater flow. The code evaluates all these components in a sequential manner by starting with rainfall and irrigation, which must be provided by the user, and continuing with interception, surface runoff, evapotranspiration, and potential recharge (water flux crossing the bottom of the soil). This potential recharge is the input to the unsaturated zone where water can flow horizontally as subsurface flow (inter flow) or vertically as percolation into the aquifer. (Author)

    Full Text Available Il contributo intende ripercorrere il ruolo che Omar Calabrese ha avuto nella fondazione della Semiotica dell’arte. Una disciplina che, in Italia, vede la sua nascita a partire dall’ultimo ventennio del secolo scorso e che lo studioso, recentemente scomparso, ha contribuito a delineare con precisione. Il volume La macchina della pittura è sicuramente il suo contributo più innovativo, più sistematico e anc’oggi attuale. All’epoca in cui è stato pubblicato, nel 1985, lanciava una duplice sfida: alla storia dell’arte tradizionale e alla semiotica. Alla prima perché imponeva un altro tipo di sguardo, capace di decifrare il modo in cui attraverso la forma è costruito il senso pittorico. Alla semiotica perché dimostra come la pittura sia in grado di produrre senso e addirittura contenga al suo interno i meccanismi per interpretarla.

    2014-11-01

    Full Text Available A partire dagli scritti di Roman Jakobson, Nicolas Ruwet, Jean-Jacques Nattiez e Gino Stefani, la relazione tra la semiotica e la musica è stata spesso affrontata da numerosi studiosi che anche oggi praticano, specie in Canada, in Finlandia e in Italia, la disciplina chiamata “semiotica (o semiologia della musica”. Negli ultimi anni, in questo ambito spesso si è preferito realizzare studi su alcuni problemi specifici piuttosto che concentrarsi su una teorizzazione generale. Al contrario, Stefano Jacoviello, dopo aver pubblicato brevi saggi di carattere prevalentemente analitico, in questo volume, di ampio respiro teorico, presenta una sorta di manifesto teso a rilanciare, specie in Italia, il ruolo della “semiotica del discorso musicale” come disciplina particolarmente adatta ad affrontare questioni teoriche generali.

    I metodi probabilistici e statistici giocano un ruolo di primo piano sia nella scienza teorica e sperimentale che nelle applicazioni ingegneristiche, costituendo pertanto un elemento essenziale del bagaglio culturale che uno studente deve acquisire fin dai primi anni di apprendimento universitario. Questo libro, che nasce dall’esperienza didattica accumulata dall’autore nell’insegnamento dei metodi sperimentali, si propone di fornire un’introduzione al calcolo delle probabilità e alla teoria degli errori facendo uso di uno stile di presentazione volutamente informale e traendo spunto da concrete applicazioni sperimentali, spesso attraverso esempi di notevole importanza storica. Così, per esempio, argomenti quali il moto browniano, la diffusione di luce, il decadimento radioattivo, la fisiologia della visione, le statistiche quantistiche e di fotorivelazione, vengono utilizzati per delucidare concetti chiave dell’analisi statistica e probabilistica.

    2010-03-01

    Full Text Available La posizione centrale nell’Egeo ed i pochi giorni di navigazione dall’Africa e dall’Egitto, come dalla Siria e Palestina, hanno reso la città di Gortina, e Creta stessa, un punto nevralgico all’interno delle rotte commerciali di collegamento e distribuzione di beni tra le sponde del Mediterraneo. Lo studio delle anfore rinvenute nelle campagne di scavo 2003-2006 presso le Terme a sud del Pretorio, ed il necessario confronto con le grandi quantità di materiali provenienti soprattutto dai contesti del Pretorio confermano questa intricata rete commerciale. Già tra Ellenismo e prima età imperiale romana, Gortina svolse una funzione di mercato di raccolta e probabilmente di smistamento delle merci provenienti dall’Occidente e dall’Egeo, assumendo poi nella piena età imperiale, un ruolo sempre più attivo nella produzione delle stesse. La mutata situazione socio-economica dell’età tardo romana - bizantina, nonché la fondazione di una nuova capitale, Costantinopoli, portò Creta e Gortina ad avere scambi commerciali e collegamenti intensi soprattutto con le aree orientali del Mediterraneo privilegiando l’importazione di prodotti dall’esterno.

    Full Text Available Con l'aumento della deregolamentazione e l'innovazione finanziaria in molti sistemi bancari nazionali, è stato suggerito che l'attuale enfasi sul controllo della massa monetaria non è più appropriato. Invece, una definizione più ampia di credito dovrebbe essere introdotto e movimenti degli aggregati creditizi dovrebbe essere controllato. L'autore sostiene che non vi è alcun meccanismo di trasmissione diretta tra un aggregato ampio credito e variazioni del debito privato e di governo, e che le autorità hanno limitato la capacità di controllare un tale aggregato. Quindi la sua scelta come l'obiettivo principale della politica monetaria sarebbe inopportuno.With increasing deregulation and financial innovation in many domestic banking systems, it has been suggested that the present emphasis on controlling the money stock is no longer appropriate. Instead, a broader definition of credit should be introduced and movements in credit aggregates should be controlled. The author argues that there is no direct transmission mechanism between a broad credit aggregate and changes in private and government debt, and that the authorities have limited ability to control such an aggregate. Therefore its choice as the main target for monetary policy would be inappropriate.JEL: E52

    RM nell'ambito delle malattie dolorose del retropiede e piu' in particolare nella sindrome dell'os trigonum, in considerazione della notevole difficolta' clinica per la corretta diagnosi. Lo studio e' stato condotto su sette pazienti che lamentavano dolore al retropiede da piu' di quattro mesi (maschi/femmine=1/6), con eta' compresa tra 16 e 22 anni (eta' media 18,6 anni); 3/7 praticavano attivita' agonistica sportiva, 4/7 danza classica. In 2/7 pazienti l'os trigonum presentava margini irregolari con sclerosi subcondrale e ampliamento della sincondrosi. In 3/7 pazienti e' stata documentata tenosinovite del tendine flessore lungo dell'alluce causata verosimilmente dalla sua compressione e spostamento all'interno della propria guaina, senza ne' alterazione dell'intensita' di segnale dell'os trigonum, ne' ampliamento della sincondrosi. In 1/7 pazienti sono stati rilevati ipertrofia dell'os trigonum, modico ampliamento della sincondrosi e segni importanti di edema midollare nell'os trigonum e nel processo posteriore dell'astragalo. In 1/7 pazienti, pur in presenza di os trigonum rilevato all'esame radiologico tradizionale, l'esame RM non ha documentato alcuno dei segni da riferire a sindrome dell'os trigonum: la diagnosi definitiva e' stata tendinite achillea. La RM e' l'unica metodica che fornisce importanti informazioni sul coinvolgimento dei tessuti molli, della superficie condro-ossea e sulle reazioni sinoviali riuscendo percio' a dimostrare chiaramente l'eventuale coesistente tenosinovite del tendine flessore lungo dell'alluce ed inoltre provvedendo a fornire informazioni dettagliate per il corretto approccio terapeutico. In conclusione, nell'ambito delle malattie dolorose del retropiede da cause ossee, laddove si sospetti clinicamente la sindrome dell'os trigonum, la non invasivita' della RM

    Pelvic floor and rectal prolapse conditions have greatly benefited by new imaging and instrumental diagnostic approaches, and especially defecography, for both pathophysiological interpretation and differential diagnosis. The authors investigated the efficacy of defecography in the assessment of rectal prolapse, and in particular the role of videproctography in diagnosis such dynamic disorders. The dynamic changes of ampulla are well depicted by videoproctography, which showed anorectum normalization and spontaneous reduction of invagination after intussusception. Defecography exhibited good capabilities in showing rectal wall function abnormalities. Finally, some features of videoproctography such as low radiation dose, non-invasiveness and ease of execution, make the examination acceptable to patients with anorectal disorders and for the follow-up of rectal prolapse. [Italian] Le malattie del pavimento pelvico e dei prolassi del retto hanno tratto numerosi vantaggi da nuovi approcci di diagnostica per immagini e strumentali, specialmente dall'esame defecografico, sia nell'interpretazione fisiopatologica che nella diagnostica differenziale dei disordini anorettali. Scopo del lavoro: valutare l'efficacia della metodica defecografica nel riconoscimento delle malattie da prolasso del retto e in particolare il ruolo svolto dalla videoproctografia nella documentazione diagnostica e nel definire i principali elementi semeiologici riscontrabili in tali malattie in modo dinamico. Le fasi dinamiche della valutazione morfologica e posizionale dell'ampolla rettale sono ben evidenti nella viedeoproctografia, che documenta dopo l'intussuscezione la normalizzazione del complesso anorettale e la riduzione spontanea dell'invaginazione parietale. In questo studio si sottolineano le possibilita' diagnostiche della defecografia integrata da videoproctografia nel riconoscimento delle malattie parietali funzionali del retto e alcune peculiarita

La formazione specifica che si articola in maniera sinergica tra laboratori e corsi teorici trova fondamento nelle discipline dello human factors, delle teorie dell’interazione e della critica del design. Il paper argomenta le ragioni, i metodi e le scelte effettuate dal gruppo di docenti che tra il 2010 e il 2014 ha progettato tale percorso didattico all’Università degli Studi della Repubblica di San Marino.ENThe transformation of the designer’s role in the contemporary social, economic and cultural context, characterized by a growing overload of visual stimuli, new technological products, and a multitude of pervasive mobile devices, led the decision to steer the graduate degree programme in design towards the multidisciplinary field of interaction design. This specific branch of learning builds its fundamentals in the synergetic teaching of theoretical and studio courses focusing on human factors, theories of interaction and design criticism. This paper investigates the motivations, the methods and the choices made by a group of professors of the University of the Republic of San Marino to create a new graduate programme in interaction design.

    Full Text Available Rabelais, Zola, Camus hanno intuito che le sentenze spesso si reggono su complessi meccanismi psicologici, oltre che sulla razionalità giuridica. Ci si chiede se queste intuizioni trovino conferma nelle più recenti acquisizioni della psicologia della decisione e delle scienze cognitive. Per rispondere al quesito si analizzano passi del Gargantua e Pantagruele, di Thérèse Raquin, de Lo straniero, mettendoli a confronto con alcuni esperimenti condotti in ambito psicologico. Si dimostra come Rabelais abbia correttamente intuito quanto rilevino le euristiche nella decisione, come Zola abbia colto il ruolo delle aspettative nella percezione da parte dei testi, come Camus abbia descritto le distorsioni che si possono produrre nella fase narrativa della testimonianza. Se ne conclude che a volte la materia della giustizia si intende meglio esplorando le opere dei grandi autori che non, per dirla con Erasmo, ammucchiando glosse su glosse.

    In the study of the climatic change tied to the anthropogenic enhancement of the greenhouse effect, a very important topic is represented by the past climate reconstruction. This because the analysis of the past variations can help in order to better understand the present trends. With this aim a research on the climatic trends in Italy has been carried out considering the main meteorological parameters. The obtained results indicate that the climate has been subject to a noticeable evolution even if, due to reduced amplitude of the variations, it is not possible to state without any doubt that it is a real climatic change. The present patterns can in fact be connected to the natural climatic variability. [Italian] Nello studio dei cambiamenti climatici legati al potenziamento antropico dell'effetto serra, un ruolo importante riveste la ricostruzione dei climi del passato, poiche' l'analisi delle variazioni passate puo' aiutare a capire meglio gli andamenti attuali.

I risultati ottenuti indicano che il clima ha subito una consistente evoluzione, anche se l'ampiezza delle variazioni non consente di affermare che si e' di fronte ad un vero e proprio cambiamento.

    Full Text Available Le celebrazioni per i 150 anni dell’Unità d’Italia offrono anche l’occasione per interrogarsi sulla storia e lo sviluppo di questo Paese, in particolare in riferimento alla cultura del mare e al sistema dei trasporti via acqua. In un paese peninsulare come l’Italia, con i suoi 7.500 chilometri di fronte d’acqua, la presenza dei porti è sempre stata elemento determinante per la crescita economica e per la sua affermazione sui mercati internazionali. Ma, dalla seconda metà del Novecento, le città e i loro porti sono andati progressivamente separandosi, determinando situazioni di forti contrasti e di continue tensioni. Solo più recentemente – a seguito della legge n. 84 del 1994 – nuove forme di ‘dialogo’ hanno consentito, in talune occasioni, di riavviare politiche di concertazione sui piani di sviluppo delle aree portuali e sul miglioramento della situazione delle zone urbane prossime ai porti. Per tutti questi motivi, l’occasione del 150esimo anniversario dell’Unità d’Italia può rappresentare un momento significativo per riprendere la riflessione sul ruolo dei porti italiani nella storia del nostro paese, ed, eventualmente, sul potenziale rafforzamento che essi possono subire, alla luce dei dati positivi ed incoraggianti dell’intero cluster marittimo in questi ultimi anni, almeno fino alla crisi congiunturale del 2008.Al tempo stesso, si può analizzare la complessa relazione porto-città, in un’ottica di mutuo riconoscimento delle rispettive esigenze e della volontà di sviluppare le proprie attività in un quadro di concreto ed efficace spirito di collaborazione, che richiede sia una maggiore conoscenza reciproca, così come una più efficace definizione degli obiettivi per il raggiungimento di una qualità urbana sostenibile e duratura.La progressiva globalizzazione dell’economia e la liberalizzazione del mercato hanno determinato una generale crescita degli scambi commerciali a livello mondiale e in

    Purpose. To evaluate the role of contrast-enhanced Magnetic Resonance Mammography (MRM) in the evaluation of the contralateral breast in patients with recently diagnosed breast cancer. Materials and methods. Fifty patients with proved unilateral breast cancer, with a negative contralateral breast at physical examination, ultrasound and mammography, were studied with a 1.5 T magnet (Siemens, Vision Plus, Germany). A bilateral breast surface coil was used. Dynamic 3D Flash T1-weighted sequences were acquired in the axial plane before and 0, 2, 4, 6 and 8 minutes after the administration of 0.1 mmol/kg of Gd-BOPTA at a flow rate of 2 ml/s followed by 10 ml of saline. The level of suspicion was reported on a scale from 0 to 5 following the BI-RADS classification, based on lesion morphology and kinetic features. The results were compared with the histological findings after biopsy or surgery. Results. Fourteen out of 50 patients (28%) had contralateral lesions identified on MRM. Biopsy was performed in four of them for suspicious lesions (BI-RADS 4) while 10 patients underwent surgery because of highly suggestive malignant lesions (BI-RADS 5). Histology diagnosed three fibroadenomas, 5 ductal carcinoma in situ, 2 lobular carcinomas in situ, 3 invasive ductal carcinomas and 1 invasive lobular carcinoma. Contrast enhanced MRM yielded no false negative and three false positives. Conclusions. Our results demonstrate a very good accuracy of Magnetic Resonance Mammography in the detection of synchronous contralateral cancer in patients with newly diagnosed breast cancer. Therefore, contrast-enhanced MRM could be introduced to screen patients with proven breast cancer before they under-go surgery. [Italian] Scopo.

Several samplings were taken to determine the concentration of nitrates and orthophosphates among the recollection of data: feeding, biomass production, flow rate, FCR supplied by 8 trout farms with the objective of estimating the quantity of wastes outputs in aquaculture through the equations of nutrient mass-balance. The obtained values of nitrates go from 0, 12 to 0, 61 mg/l, orthophosphates from non-detectable for the method to 1,17mg/l. According to the constants used in the equations and the data obtained from trout farms the total production estimated were 5890 Kg of solids wastes, 1955 Kg of Total N and 217 kg of Total P a year, what is equal to 115 Kg of solids, 38 kg of NT and 4, 2 Kg of PT for each ton of produced fish. With a flow rate of 5 m3/s estimate for the receiving effluent it is obtained concentrations of 0,056 for SS, 0,02 of NT and 0,002 of PT. These obtained values are theoretical, but the estimate of wastes output through the nutrient mass-balance constitutes a simple, practical and low cost tool that contributes to the sustainable development of aquaculture and the environments.

    Full Text Available En este trabajo se aplica la técnica de simulación de Monte Carlo para modelar el balance hídrico de una represa que surte de agua potable a la ciudad de Tunja en Colombia. Se analizan dos fuentes alternas de agua potable. Con el modelo se establece que la mejor fuente alternativa para el abastecimiento de agua para Tunja en los próximos cuarenta años es el embalse de La Copa. Se desarrolla un método para ajustar la precipitación, la infiltración, la escorrentía, la evapotranspiración, y el caudal subterráneo y el de extracción; a variables aleatorias. Las proyecciones generadas por medio de esta simulación son estimaciones realistas, ya que la simulación de Monte Carlo permite modelar los flujos de entrada y de salida pertenecientes al balance hídrico como variables estocásticas, de manera que se incluye la incertidumbre inherente a eventos naturales como las condiciones climáticas.

    Full Text Available Objective: To quantify the differences in the trajectory of the center of pressure (COP in an elderly population and a group of children. Methods: This was a cross-section study for which a convenience sample of 38 elderly adults and 20 children was obtained. The parameters studied were: area and average speed of excursion of the COP, and the frequency bands (0.0625; 0.125; 0.25; 0.5; 1, 2 y 4 Hz. Results: During the standing balance evaluation in the absence of the visual system, there are significant differencesin the area and average velocity of the COP. The group of children generates much more area of COP during the test than the elder group (p = 0.009. However, postural adjustments in children are faster than those of the older group (p = 0.002. Conclusions: In the absence of the visual system, the elderly group had lower area and speed of postural adjustment than the younger group. The latter group used the vestibular and somatosensory systems to maintain standing balance.

We formalize the idea of balance of power: players fight very inefficient players but play softly versus equally (or more) efficient players. This theory of conduct predicts that entry by new firms leads to a less aggressive outcome if it creates a balance of power.

    Introduzione: le patologie del bambino, soprattutto se gravi e durature, possono essere definite come “malattie della famiglia” a causa dell’intensità di assistenza richiesta, delle difficoltà organizzative quotidiane e dello stress causato. Obiettivo: identificare il ruolo di alcuni potenziali fattori di rischio coinvolti nella rottura di famiglie di bambini leucemici.

    Materiali e metodi: mediante l’uso di questionari, sono state studiate, durante l’anno 2002, 150 cartelle cliniche di bambini leucemici dell’ospedale pediatrico “Santobono-Pausillipon”- Dipartimento di Oncologia; 11 casi sono stati esclusi per incompletezza dei dati. Outcome è stata considerata la “separazione familiare.” Sono state analizzate le seguenti variabili: trapianto di midollo osseo, lavoro del padre, della madre e loro età ed educazione, sesso ed età del bambino (CA, numerosità della famiglia, stato socio-economico, probabilità clinica di guarire (CPR, appartenenza ad una associazione. Sono state condotte analisi bivariate e logistiche. Risultati: all’analisi bivariata CA e CPR, entrambi stratificati in tre livelli, sono risultati associati alla separazione. L’Odds Ratio grezzo (OR della separazione familiare con CA di 5/10 anni e bambini di 11 anni o più a confronto con quelli d’età di 0/4 era, rispettivamente, di 8.68 (p=0.02 e di 5.7 (p=0.07. L’OR grezzo della separazione con un CPR medio e un CPR buono confrontato con un CPR basso ha dato rispettivamente 0.35 (p=0.02 e 0.08 (p‹0.001. Un modello logistico che includeva CPR come variabile principale e controllata per CA ha evidenziato che la probabilità di guarigione è media o alta e, dopo aver aggiustato per l’età del bambino, è stato ottenuto un rischio di rottura familiare rispettivamente di 0.29 (p=0.01 e 0.08 (p=0.02.

    Conclusioni: la rottura dell’unità familiare è evento frequente in caso di grave

En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo. El concepto Potencial de agua del suelo es un criterio para esta energía.

In particular, the temperature as a function of height is considered, as are the damping length dependence of the global energy balance in the region between the base of the transition region and the critical point, and the effects of changing the amount of coronal heating, the stellar mass, and the stellar radius. Models of coronal loops are more briefly discussed. The chromosphere is then included in the discussion of the energy balance, and the connection between global energy balance and global thermal stability is addressed. The observed positive correlations between the chromospheric and coronal energy losses and the pressure of the transition region is qualitatively explained

    Full Text Available Spesso origine dei primi insediamenti urbani, i corsi d’acqua sono stati nei secoli fonte di sostentamento per le popolazioni e strumento di scambio tra genti e culture. Proprio per il loro scorrere attraverso il territorio, essi sono per definizione luoghi di relazione, di intersezione tra diverse realtà urbane dove si incontrano ambiente, architettura, pianificazione, trasporti ma anche arte, cultura e turismo. Per questa loro caratteristica, le vie d’acqua rappresentano una grande potenzialità per lo sviluppo del territorio sia in termini di mobilità – di merci e di persone - che di turismo sostenibile. La loro riqualificazione permette di recuperare il ruolo di spazio pubblico e di paesaggio rurale, urbano e turistico di qualità; luoghi di fruizione turistica, culturale, gastronomica e sportiva, quindi di qualità della vita. Dopo decenni di oblio, sollecitata dal rinnovato interesse verso questi assi e anche dalle direttive dell’Unione Europee, l’Italia e, in particolare il Nord del paese, muove i primi passi verso la valorizzazione delle waterway a fini turistico-culturali, aprendo nuove possibilità di sviluppo del territorio. Sia pur con ritardo rispetto ad altri Paesi, che da anni e in diverse forme valorizzano e “sfruttano” le vie d’acqua, si avverte anche in Italia un cambio di mentalità che vede nell’uso e nel recupero di tale risorsa uno strumento importante per garantire la sostenibilità ambientale ed economica e il recupero di una identità culturale quasi dimenticata.

    Energy Technology Data Exchange (ETDEWEB)

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

Robbe-Grillet, dal canto suo, pur ispirandosi alla vicenda di Edipo nella sua opera d’esordio, non esiterà in seguito a condannare la tragedia come ingannevole forma di compromesso tra l’uomo e le choses e a rifiutare, insieme a essa, la “metafisica della presenza” di cui sarebbe espressione. Altri nouveaux romanciers – tra cui Michel Butor – preferiranno invece sfruttarne le potenzialità in maniera inedita, ritenendola uno sfondo mitopoietico ideale su cui far emergere i tratti essenziali di una condizione esistenziale all’insegna del crollo delle grandi narrazioni. Al di là delle diverse intenzioni, la rivisitazione della “forma” in sé (in chiave parodica o attualizzante ha di conseguenza svolto un ruolo cruciale sia nella decostruzione del “personaggio-uomo”, sia nella contestazione delle cosiddette “nozioni scadute” tanto indigeste a questa eterogenea collection d’écrivains. Da Les gommes (1953 a L’emploi du temps (1956, per arrivare sino a Sphinx en chapeau (1984, si potrebbero menzionare numerosi esempi a tal riguardo, segno di una fascinazione costante, ma non per questo meno conflittuale, destinata a esercitare una profonda influenza su alcuni dei maggiori dei successi editoriali dello sperimentalismo francese.

    Full Text Available The essay aims at showing the development of the critical thought about Prometheus Bound that underlied the staging of this tragedy at the Teatro Greco of Siracusa during the spring of 2012. The performance was directed by the author of these pages for the Istituto nazionale del dramma antico (premiere: Siracusa, 11th May. In the framework of a hermeneutic paradigm based on the ‘critically’ untimely nature of the classic, the staging of Prometheus here discussed wanted to inquire the role of sight in the orchestration of this tragedy, as well as to account for the way time is treated in the text. In the light of this approach, Prometheus looks like a cruel portrait of a world in a state of crisis, suspended between two disasters (one has just ended, the other is looming ominously on the horizon; from its remote distance, such a world gives us an image both lucid and alienated of our present.Il saggio si propone di restituire il percorso di riflessione critica intorno al Prometeo incatenato che nella primavera del 2012 ha sostanziato il processo di messa in scena della tragedia presso il teatro greco di Siracusa, curata dall’autore di queste pagine per conto dell’Istituto nazionale del dramma antico (debutto: Siracusa, 11 maggio. Entro un paradigma ermeneutico fondato sul principio dell’inattualità ‘critica’ del classico, l’allestimento del Prometeo di cui qui si riferisce punta a indagare il ruolo svolto dallo sguardo nell’orchestrazione della tragedia, così come a render ragione del trattamento cui la funzione tempo è sottoposta nell’opera. Sulla base di un simile approccio, il Prometeo appare così come un crudele ritratto di un mondo in crisi sospeso tra due catastrofi (l’una appena trascorsa, l’altra minacciosamente incombente all’orizzonte; un mondo che dalla sua remota distanza ci consegna un’immagine ad un tempo lucida e straniata del nostro presente.

    Full Text Available 'In Balance With' (2012 is a live performance with Courtney Kessel and her daughter, Chloé, sitting at opposite ends of a seesaw. During the 30-minute performance, Kessel adds items representative of their lives to Chloé's side of the seesaw. After each group of items is added, she returns to her side to check the balance. Toys, violin, research books, food, pots, tools, and laundry are strapped on to the seesaw. The audience witnesses the struggle to create a balance between work, home, research, and play as a single mother and artist. As equilibrium is achieved, Kessel stills labors to maintain the balance until Chloé is ready to get down, thus signaling that her work can only happen when her daughter is cared for and occupied.

    The energy balances of the Danish Statistical Office are the designation of the goods balances, which are tabulated for each energy article in both physical entities (quantities) and in base rates (values). The balance concept is connected to the definition supply = use, which is the basis for the construction of the system. The supply is determined as the sum of two items: import and production while the total use is the sum of 138 items: export, waste and transmission loss, stock increase, input in lack of the 130 industries, and private consumption divided into 5 consumption groups. The statistical analysis is performed yearly in both quantities and values for 35 energy articles. Values are computed for base rates, profits, taxes, VAT and market prices (buyer's price), respectively. The energy balances from 1975 to 2000 are presented for comparison. (EHS)

  10. Watt and joule balances

    Robinson, Ian A.

    2014-04-01

    The time is fast approaching when the SI unit of mass will cease to be based on a single material artefact and will instead be based upon the defined value of a fundamental constant—the Planck constant—h . This change requires that techniques exist both to determine the appropriate value to be assigned to the constant, and to measure mass in terms of the redefined unit. It is important to ensure that these techniques are accurate and reliable to allow full advantage to be taken of the stability and universality provided by the new definition and to guarantee the continuity of the world's mass measurements, which can affect the measurement of many other quantities such as energy and force. Up to now, efforts to provide the basis for such a redefinition of the kilogram were mainly concerned with resolving the discrepancies between individual implementations of the two principal techniques: the x-ray crystal density (XRCD) method [1] and the watt and joule balance methods which are the subject of this special issue. The first three papers report results from the NRC and NIST watt balance groups and the NIM joule balance group. The result from the NRC (formerly the NPL Mk II) watt balance is the first to be reported with a relative standard uncertainty below 2 × 10-8 and the NIST result has a relative standard uncertainty below 5 × 10-8. Both results are shown in figure 1 along with some previous results; the result from the NIM group is not shown on the plot but has a relative uncertainty of 8.9 × 10-6 and is consistent with all the results shown. The Consultative Committee for Mass and Related Quantities (CCM) in its meeting in 2013 produced a resolution [2] which set out the requirements for the number, type and quality of results intended to support the redefinition of the kilogram and required that there should be agreement between them. These results from NRC, NIST and the IAC may be considered to meet these requirements and are likely to be widely debated

    Full Text Available Obiettivo del lavoro è illustrare l’efficacia dei marchi ambientali nella valorizzazione dei piccoli comuni dell’entroterra, sia dal punto di vista della comunicazione turistica che da quello della qualità del territorio. La ricerca si focalizza sulla Regione Marche. Si analizzano le modalità di sfruttamento e valorizzazione del marchio Bandiera Arancione di tutti i comuni che hanno ricevuto il riconoscimento, oltre che la percezione degli enti locali circa le performance turistico-ambientali conseguite grazie ad esso. L’indagine è stata svolta somministrando un questionario (metodo CAWI ai referenti dei 19 comuni Bandiera Arancione 2014. Dallo studio emerge come essi non sfruttino appieno le potenzialità offerte dalla certificazione, sia in termini di co-branding che di coinvolgimento degli stakeholders, ma riconoscano, tuttavia, l’importanza strategica rispetto alle finalità che l’adesione a Bandiera Arancione si propone di raggiungere a beneficio del territorio. The main purpose of this paper was to determine the extent to which environmental awards may help enhancing the small-towns heritage. Focus was set on the Orange Flag to understand if municipalities properly take advantage of the award both in their communication policies and in the sustainable development of their territory. The survey was based on a questionnaire (CAWI method forwarded to the 2014 Orange Flag municipalities in the Marche region. The research revealed that municipalities do not take full advantage of the possibilities provided by the award mainly in terms of co-branding and stakeholders’ involvement. Even if they recognize great validity to the programme, the findings raised in this paper suggest a more efficient use of the award. In particular, a better use of co-branding policies and a wider sharing of sustainability issues are suggested.

    Full Text Available I macrofagi sono cellule del sistema immunitario che svolgono un ruolo fondamentale nel meccanismo di difesa dell’ospite contro gli agenti patogeni. Attualmente è ancora poco chiara la dinamica del loro intervento e della risposta umorale nel favorire l’attività fagocitaria nei confronti di Mycoplasma mycoides subsp. mycoides small colony (Mmm-SC, agente eziologico della pleuropolmonite contagiosa bovina (PPCB. Questo studio è stato condotto al fine di valutare le modificazioni morfologiche della superficie macrofagica in seguito all’infezione in vitro con Mmm-SC in presenza di siero immune bovino. L’analisi morfologica dei macrofagi è stata condotta su colture, 6 ore dopo l’infezione, utilizzando l’analisi tridimensionale della microscopia elettronica a scansione. I macrofagi non infettati, in presenza di siero negativo o immune, e i macrofagi infettati con Mmm-SC, in assenza di siero, hanno mostrato solo lievi modificazioni della loro superficie. Al contrario, in colture di macrofagi infettati e in presenza di siero immune sono state osservate marcate modificazioni della superficie cellulare, come ampi veli e filopodi (indicatori di attivazione cellulare, e piccoli aggregati di micoplasmi in stretto contatto con le membrane macrofagiche. I risultati suggeriscono che la risposta umorale specifica per Mmm-SC può contribuire a innescare l’attività fagocitaria dei macrofagi.

    The paper deals with an evaluation of hydrogen sulphide emissions from leather tanning industries and water purification plants in the leather district in Tuscany. The aim of the work is to correlate different sources emissions of the area with pollutant concentrations recorded by the monitoring network. Global quantities of treated substances, different plants typologies and operating mode, have been considered, following the indications of the ARPAT's archives. This analysis, updated to 1998, gives interesting information about the trend of emissions and their weight on air quality: the effect of tanning leather industries emissions during the 'pickel' operation results greater than the average purification plants contribution to air quality, even if, cause of the high quantity of treated sulphides, the weight of purification plants remains important. The trend of measured concentration of pollutant in air shows a clear improvement of air quality during last three years (1997-199).

    The description is given of a manipulator of the type comprising a master arm and a slave arm, capable of working in a containment restricted by a wall fitted with an aperture to introduce the slave arm into the containment. According to the invention this manipulator is permanently balanced irrespective of its distortions when it is secured to the wall of the containment in which it is desired to work. The entire manipulator is also balanced when being set up and when moved outside the containment, in relation to a supporting axle. This result is achieved in a simplified manner by giving homothetic shapes to the various component parts of the slave and master arms, the master arm having at least one balancing weight [fr

With this study, we apply Grimens’ (2009) analytical connection between trust and power to explore how trust and power appear in preventive health checks...... of clinical encounters. Results: From the empirical data, we identified three dimensions of respect: respect for the patient’s autonomy, respect for professional authority and respect as a mutual exchange. A balance of respect influenced trust in the relationship between GP and patients and the transfer...... of power in the encounter. The GPs articulated that a balance was needed in preventive health checks in order to establish trust and thus retain the patient in the clinic. One way this balance of respect was carried out was with the use of humour. Conclusions: To retain patients without formal education...

    It is shown that, traditionally, the energy balance of Georgia is in deep deficit. The suggestions for its improvement are provided in the Article. The country imports almost all amount of oil and natural gas. Electricity balance is relatively stable. In the recent years, some amount of electricity is exported to the neighboring countries. Generally, the country satisfies only 30–35% of own energy consumption by local generation, and the rest amount of resources are imported from abroad. The reason of deficit to some extent is irrational and wasteful consumption of energy resources. The article examines the organizational difficulties in drawing up energy balance of Georgia and statistical problems of recording of energy production and consumption at the initial stage of market economy.

  19. Sport-specific balance.

    2014-05-01

    This review includes the latest findings based on experimental studies addressing sport-specific balance, an area of research that has grown dramatically in recent years. The main objectives of this work were to investigate the postural sway response to different forms of exercise under laboratory and sport-specific conditions, to examine how this effect can vary with expertise, and to provide examples of the association of impaired balance with sport performance and/or increasing risk of injury. In doing so, sports where body balance is one of the limiting factors of performance were analyzed. While there are no significant differences in postural stability between athletes of different specializations and physically active individuals during standing in a standard upright position (e.g., bipedal stance), they have a better ability to maintain balance in specific conditions (e.g., while standing on a narrow area of support). Differences in magnitude of balance impairment after specific exercises (rebound jumps, repeated rotations, etc.) and mainly in speed of its readjustment to baseline are also observed. Besides some evidence on an association of greater postural sway with the increasing risk of injuries, there are many myths related to the negative influence of impaired balance on sport performance. Though this may be true for shooting or archery, findings have shown that in many other sports, highly skilled athletes are able to perform successfully in spite of increased postural sway. These findings may contribute to better understanding of the postural control system under various performance requirements. It may provide useful knowledge for designing training programs for specific sports.

    Directory of Open Access Journals (Sweden)

    Angus Deaton

    2012-04-01

    Full Text Available Nei primi anni ’50, Franco Modigliani e il suo studente Richard Brumberg elaborarono una teoria della spesa fondata sull’idea che gli individui effettuano scelte intelligenti su quanto desiderano spendere a ogni età, con il solo limite delle risorse disponibili nel corso della loro vita. Attraverso l’accumulo e il decumulo delle attività, chi lavora può provvedere alla propria pensione e, più in generale, può adattare i propri modelli di consumo alle esigenze che si presentano alle diverse età, indipendentemente dal reddito disponibile in ogni momento della sua vita. Questa semplice teoria conduce a previsioni rilevanti e non scontate per l’economia nel suo complesso, ad esempio che il risparmio nazionale dipende dal tasso di crescita del reddito nazionale e non dal suo livello, e che esiste una semplice relazione tra il livello della ricchezza nel sistema economico e la lunghezza del periodo trascorso in pensione. Tali previsioni, non verificabili negli anni ’50, hanno trovato considerevole sostegno empirico in successivi lavori di Modigliani e di altri ricercatori. Sebbene nel corso degli anni la teoria del consumo abbia subito numerosi attacchi, i più recenti dei quali mossi da una coalizione di psicologi ed economisti, l’ipotesi del ciclo vitale rimane una parte essenziale del pensiero degli economisti. Senza di essa avremmo molto meno da dire circa molte importanti questioni, quali l’offerta pubblica e privata di previdenza sociale, gli effetti del mercato azionario sull’economia, le conseguenze dei mutamenti demografici sul risparmio nazionale, il ruolo del risparmio nella crescita economica e le determinanti della ricchezza nazionale.  In the early '50s, Franco Modigliani and his student Richard Brumberg elaborated a theory of expenditure based on the idea that individuals make smart choices about how they want to spend at any age, with the only limit of the available resources in the course of

  6. Load Balancing in Hypergraphs

    Science.gov (United States)

    Delgosha, Payam; Anantharam, Venkat

    2018-03-01

    Consider a simple locally finite hypergraph on a countable vertex set, where each edge represents one unit of load which should be distributed among the vertices defining the edge. An allocation of load is called balanced if load cannot be moved from a vertex to another that is carrying less load. We analyze the properties of balanced allocations of load. We extend the concept of balancedness from finite hypergraphs to their local weak limits in the sense of Benjamini and Schramm (Electron J Probab 6(23):13, 2001) and Aldous and Steele (in: Probability on discrete structures. Springer, Berlin, pp 1-72, 2004). To do this, we define a notion of unimodularity for hypergraphs which could be considered an extension of unimodularity in graphs. We give a variational formula for the balanced load distribution and, in particular, we characterize it in the special case of unimodular hypergraph Galton-Watson processes. Moreover, we prove the convergence of the maximum load under some conditions. Our work is an extension to hypergraphs of Anantharam and Salez (Ann Appl Probab 26(1):305-327, 2016), which considered load balancing in graphs, and is aimed at more comprehensively resolving conjectures of Hajek (IEEE Trans Inf Theory 36(6):1398-1414, 1990).

    A method has been developed for continuous cell voltage balancing for rechargeable batteries (e.g. lithium ion batteries). A resistor divider chain is provided that generates a set of voltages representing the ideal cell voltage (the voltage of each cell should be as if the cells were perfectly balanced). An operational amplifier circuit with an added current buffer stage generates the ideal voltage with a very high degree of accuracy, using the concept of negative feedback. The ideal voltages are each connected to the corresponding cell through a current- limiting resistance. Over time, having the cell connected to the ideal voltage provides a balancing current that moves the cell voltage very close to that ideal level. In effect, it adjusts the current of each cell during charging, discharging, and standby periods to force the cell voltages to be equal to the ideal voltages generated by the resistor divider. The device also includes solid-state switches that disconnect the circuit from the battery so that it will not discharge the battery during storage. This solution requires relatively few parts and is, therefore, of lower cost and of increased reliability due to the fewer failure modes. Additionally, this design uses very little power. A preliminary model predicts a power usage of 0.18 W for an 8-cell battery. This approach is applicable to a wide range of battery capacities and voltages.

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

    Currently, one of the main metrological noncontact temperature measurement challenges is the emissivity uncertainty. This paper describes a pyrometer with emissivity effect diminishing through the use of a measuring scheme with tracking balancing in which the radiation receiver is a null-indicator. In this paper the results of the prototype pyrometer absolute error study in surfaces temperature measurement of aluminum and nickel samples are presented. There is absolute error calculated values comparison considering the emissivity table values with errors on the results of experimental measurements by the proposed method. The practical implementation of the proposed technical solution has allowed two times to reduce the error due to the emissivity uncertainty.

Since 1975, the energy consumption has been on the same level with minor fluctuations which are mainly due to the climate. The energy balances is an account of production, import and export, and consumption of energy. The consumption is accounted as physical amounts as well as gross consumption. Also, accounts are presented of the costs of energy in basis prices and in market prices, including excises on energy, CO 2 , and SO 2 . (LN)

    In this work the electronic properties and the composition of the three layers (diffusive, catalytic and outermost) are studied separately. In the first part, an anomalous behaviour of the photoemission peaks from the diffusive layer has been evidenced and correlated with the macroscopic electronic conductivity. In the second part, the electronic properties of the PT clusters are compared with the macroscopic electron conductivity. In the second part, the electronic properties of the PT clusters are compared with those of PT bulk, as a function of thermal treatment and after half-cell measurements. A correlation of the binding energy, asymmetry and width of the peaks with the different status of the metal has been attempted. [Italian] Il lavoro consiste di due parti: l'una dedicata allo studio delle caratteristiche dello strato di supporto e diffusivo, l'altra allo studio dello strato catalizzatore. Nella prima parte, la presenza anomala negli spettri XPS viene messa in relazione con la conducibilita' elettronica delle nanoparticelle metalliche in funzione delle condizioni di preparazione degli elettrodi e delle simulazioni di funzionamento. Sono messe in evidenza le problematiche connesse all'interpretazione degli spettri di fotoemissione da sistemi costituiti da particelle nanometriche, intermedi tra la condizione di atomo isolato e quella del solido, in cui gli effetti di dimensione svolgono un ruolo importante nel determinare risposte diverse ed inaspettate rispetto al comportamento del metallo massivo.

    To determine the effects of dynamic posturographic balance training versus conventional balance training in improving mobility and balance in elderly. Methodology: Forty subjects between 50 to 80 years of age were selected via non-probability convenience sampling technique, for this randomized controlled trial. Both females and males with no major co-morbid conditions and cognitive impairments were recruited and randomized via coin toss method into two equal groups: Dynamic Posturographic balance training (DPG) group and Conventional balance training (CBT) group. The DPG training was provided via Biodex Balance System (Static and Dynamic). Both groups received interventions 3 times (35 to 45min each day) a week for 8 weeks, after which terminal assessment was done. Data were collected on demographic profile, balance via berg balance score and mobility by using Timed Up and Go Test. Independent samples t test was used to check difference between CBT group and DPG Group and repeated measures Analysis of Variance (ANOVA) was used for within-group analysis. Results: Baseline analysis of Berg balance scale and timed up and go test between two groups showed no significant difference with (p 0.805 and 0.251, respectively). After 8 weeks of intervention, there was significant difference between the groups in both variables (p 0.019 and 0.001, respectively). Conclusion: Dynamic posturographic balance training was more effective in improving dynamic balance and mobility in elderly population in comparison to conventional balance training. (author)

    2008-01-01

    Balance function begins to decline from middle age on, and poor balance function increases the risk of fall and injury. Suitable exercise training may improve balance function and prevent accidental falls. The coordination of visual, proprioceptive, vestibular and musculoskeletal system is important to maintain balance. Balance function can be evaluated by functional balance testing and sensory organization testing. Tai Chi Chuan (TC) is a popular conditioning exercise in the Chinese community, and recent studies substantiate that TC is effective in balance function enhancement and falls prevention. In studies utilizing functional balance testing, TC may increase the duration of one-leg standing and the distance of functional reach. In studies utilizing sensory organization testing, TC improves static and dynamic balance, especially in more challenging sensory perturbed condition. Therefore, TC may be prescribed as an alternative exercise program for elderly subjects or balance-impaired patients. Participants can choose to perform a complete set of TC or selected movements according to their needs. In conclusion, TC may improve balance function and is appropriate for implementation in the community.

    Since 2010, an increasing interest in more portable and flexible hardware for balance and posture assessment led to previously published studies determining whether or not the Wii Balance Board could be used to assess balance and posture, both scientifically and clinically. However, no previous studies aimed at comparing results from different Wii Balance Boards for clinical balance evaluation exist. The objective of this crossover study is to assess the interchangeability of the Wii Balance Board. A total of 6 subjects participated in the study and their balance was assessed using 4 different Wii Balance Boards. Trials were recorded simultaneously with Wii Balance Boards and with a laboratory force plate. Nine relevant clinical parameters were derived from center of pressure displacement data obtained from Wii Balance Board and force plate systems. Intraclass correlation coefficients (ICC), F tests, and Friedman tests were computed to assess the agreement between trials and to compare the Wii Balance Board and force plate results. Excellent correlations were found between the Wii Balance Board and force plate (mean ρ =.83). With the exception of 2 parameters, strong to excellent agreements were found for the 7 remaining parameters (ICC=.96). No significant differences were found between trials recorded with different Wii Balance Boards. Our results indicate that for most of the parameters analyzed, balance and posture assessed with one Wii Balance Board were statistically similar to results obtained from another. Furthermore, the good correlation between the Wii Balance Board and force plate results shows that Wii Balance Boards can be reliably used for scientific assessment using most of the parameters analyzed in this study. These results also suggest that the Wii Balance Board could be used in multicenter studies and therefore, would allow for the creation of larger populations for clinical studies.

    Dynamic balance is vitally important for most sports and activities of daily living, so the assessment of dynamic stability has become an important issue. In consequence, a large number of balance tests have been developed. However, it is not yet known whether these tests (i) measure the same construct and (ii) can differentiate between athletes with different balance expertise. We therefore studied three common dynamic balance tests: one-leg jump landings, Posturomed perturbations and simulated forward falls. Participants were 24 healthy young females in regular training in either gymnastics (n = 12) or swimming (n = 12). In each of the tests, the participants were instructed to recover balance as quickly as possible. Dynamic stability was computed by time to stabilization and margin of stability, deduced from force plates and motion capture respectively. Pearson's correlations between the dynamic balance tests found no significant associations between the respective dynamic stability measures. Furthermore, independent t-tests indicated that only jump landings could properly distinguish between both groups of athletes. In essence, the different dynamic balance tests applied did not measure the same construct but rather task-specific skills, each of which depends on multifactorial internal and external constraints. Our study therefore contradicts the traditional view of considering balance as a general ability, and reinforces that dynamic balance measures are not interchangeable. This highlights the importance of selecting appropriate balance tests. Copyright © 2018 Elsevier B.V. All rights reserved.

    2011-03-01

    The relationship between balance ability and sport injury risk has been established in many cases, but the relationship between balance ability and athletic performance is less clear. This review compares the balance ability of athletes from different sports, determines if there is a difference in balance ability of athletes at different levels of competition within the same sport, determines the relationship of balance ability with performance measures and examines the influence of balance training on sport performance or motor skills. Based on the available data from cross-sectional studies, gymnasts tended to have the best balance ability, followed by soccer players, swimmers, active control subjects and then basketball players. Surprisingly, no studies were found that compared the balance ability of rifle shooters with other athletes. There were some sports, such as rifle shooting, soccer and golf, where elite athletes were found to have superior balance ability compared with their less proficient counterparts, but this was not found to be the case for alpine skiing, surfing and judo. Balance ability was shown to be significantly related to rifle shooting accuracy, archery shooting accuracy, ice hockey maximum skating speed and simulated luge start speed, but not for baseball pitching accuracy or snowboarding ranking points. Prospective studies have shown that the addition of a balance training component to the activities of recreationally active subjects or physical education students has resulted in improvements in vertical jump, agility, shuttle run and downhill slalom skiing. A proposed mechanism for the enhancement in motor skills from balance training is an increase in the rate of force development. There are limited data on the influence of balance training on motor skills of elite athletes. When the effectiveness of balance training was compared with resistance training, it was found that resistance training produced superior performance results for

    Obiettivi: valutare l’appropriatezza organizzativa dei ricoveri effettuati in un Policlinico Universitario attraverso la comparazione di due metodi, dei quali uno basato sui dati della scheda di dimissione ospedaliera ed utilizza, rispettivamente, i sistemi di classificazione iso-gravità APR-DRG e Disease Staging e l’altro sulla revisione delle cartelle cliniche mediante il PRUO.

    Metodi: oggetto di analisi sono i ricoveri ordinari effettuati nell’anno 2001 ed afferenti ai DRG inclusi nella delibera della Giunta Regionale del Lazio 864/2002 che recepisce il D.P.C.M. 29/11/2001 sui livelli essenziali di assistenza.

    Risultati: i risultati evidenziano che le due varianti del
    metodo basato sulla SDO (metodo APPRO mostrano quote di ricoveri inappropriati sovrapponibili rispetto al complesso dei ricoveri oggetto di analisi, ma con differenze anche rilevanti tra APR-DRG e Disease Staging in relazione ai singoli DRG considerati, riconducibili ai diversi algoritmi di attribuzione del livello di severità utilizzati dai due sistemi. L’analisi campionaria effettuata con il metodo PRUO su casi afferenti ai DRG della DGR 864/2002 caratterizzati da livelli di severità minimi evidenzia una proporzione di ricoveri inappropriati superiore a quella determinata tramite i metodi basati sulla SDO. Tale differenza è verosimilmente dovuta al ruolo del valore delle soglie percentuali di accettabilità individuate dalla Regione Lazio per ciascun DRG: le quote di ricoveri che eccedono tali soglie sono considerate inappropriate.

    Conclusioni: sulla base dei risultati ottenuti gli autori
    descrivono gli interventi organizzativi adottati per ottimizzare il contesto di erogazione delle prestazioni
    oggetto di analisi, discutono vantaggi e limiti dei metodi SDO-based e del metodo analitico PRUObased e ne propongono l

    Balance training is an effective intervention to improve static postural sway and balance. The purpose of the present study was to investigate the effectiveness of the Nintendo Wii Fit Plus exercises for improving balance ability in healthy collegiate students in comparison with a typical balance training program. Forty students were randomly divided into two groups, a traditional (T group) and a Nintendo Wii group (W group) performed an 8 week balance program. The "W group" used the interactive games as a training method, while the "T group" used an exercise program with mini trampoline and inflatable discs (BOSU). Pre and Post-training participants completed balance assessments. Two-way repeated measures analyses of variance (ANOVAs) were conducted to determine the effect of training program. Analysis of the data illustrated that both training program groups demonstrated an improvement in Total, Anterior-posterior and Medial Lateral Stability Index scores for both limbs. Only at the test performed in the balance board with anterior-posterior motion, the improvement in balance ability was greater in the "T group" than the "W group", when the assessment was performed post-training (p=0.023). Findings support the effectiveness of using the Nintendo Wii gaming console as a balance training intervention tool.

    Gay Renouf has opted for a work/life balance; with a chemistry degree she joined the Saskatchewan Research Council out of graduate school in 1986. She first worked on understanding surfactants in emulsions and then dealt more with petroleum engineering issues like pipeline specifications. She is looking at waterfloods in heavy and medium gravity pools and has discovered factors helping to produce heavy oil waterfloods. But all Renouf's life is not devoted to her work: she has been working part-time, spending her free time being a parent, training for marathons and being a running coach. Renouf believes that her passion for running is consistent with her work as a scientist.

    In essentially all countries, responsibilities for child care, cooking, cleaning, and other homemaking tasks fall predominantly on the wife and mother. In addition, the childbearing years come during the period when a physicist must study hard, work long hours on research, and take temporary positions, often abroad. Thus, balancing family and career has long been one of the major barriers to women's participation in science and engineering fields, including physics. While many young women believe that they must choose between having children and having a science career, the fact is that the majority of women physicists in both developing and developed countries have successfully done both. This paper summarizes some ideas and recommendations raised in discussions, especially focused on easing the challenges of having children while in temporary jobs, returning to physics after a career break, the need for "family-friendly" working conditions, and the dual-career problem facing couples where both are scientists.

    Full Text Available Problems in attaining language mastery with students from diverse language backgrounds and levels of ability confront educators around the world. Experiments, research, and experience see positive effects of adding sign language in communication methods to pre-school and K-12 education. Augmentative, alternative, interactive, accommodating, and enriching strategies using sign language aid learners in balancing the skills needed to mastery of one language or multiple languages. Theories of learning that embrace play, drama, motion, repetition, socializing, and self-efficacy connect to the options for using sign language with learners in inclusive and mainstream classes. The methodical use of sign language by this researcher-educator over two and a half decades showed signing does build thinking skills, add enjoyment, stimulate communication, expand comprehension, increase vocabulary acquisition, encourage collaboration, and helps build appreciation for cultural diversity.

    2014-02-01

    When multiple channels are employed in a pulse-Doppler radar, achieving and maintaining balance between the channels is problematic. In some circumstances the channels may be commutated to achieve adequate balance. Commutation is the switching, trading, toggling, or multiplexing of the channels between signal paths. Commutation allows modulating the imbalance energy away from the balanced energy in Doppler, where it can be mitigated with filtering.

    The balance of military forces is meant to prevent war. But it is a very precarious balance, which becomes all the more dubious when the deterrent is no longer psychologically effective: when the country attacked is deterred from striking back with nuclear weapons. A unilateral disarmament above the overkill level would be possible without endangering the balance. It would improve the climate for mutual disarmament.

    This paper explores the logic of balancing in structural realist theory. Arguably, the durability of the unipolar moment is a challenge to the logic of balancing. The paper uses the tools of microeconomics to build a mathematical model of structural realism. The simple model reiterates...... the structural realist prediction that the weaker states should balance the unipole. Under a slight model extension, it is shown that efforts to balance in separate capabilities always tends to offset each other. Under this extension, the durability of the unipolar moment is in fact consistent...

  20. Balancing safety and economics

    International Nuclear Information System (INIS)

    Kroeger, W.; Fischer, P.U.

    2000-01-01

    The safety requirements of NPPs have always aimed at limiting societal risks. This risk approach initially resulted in deterministic design criteria and concepts. In the 1980s the paradigm 'safety at all costs' arose and often led to questionable backfitting measures. Conflicts between new requirements, classical design concepts and operational demands were often ignored. The design requirements for advanced reactors ensure enhanced protection against severe accidents. Still, it is questionable whether the 'no-damage-outside-the-fence' criteria can be achieved deterministically and at competitive costs. Market deregulation and utility privatisation call for a balance between safety and costs, without jeopardising basic safety concepts. An ideal approach must be risk-based and imply modern PSAs and new methods for cost-benefit and ALARA analyses, embed nuclear risks in a wider risk spectrum, but also make benefits transparent within the context of a broader life experience. Governments should define basic requirements, minimum standards and consistent comparison criteria, and strengthen operator responsibility. Internationally sufficient and binding safety requirements must be established and nuclear technology transfer handled in a responsible way, while existing plants, with their continuous backfitting investments, should receive particular attention.

    Hiergesell, R.A.; Dixon, K.L.

    1996-06-01

    A water budget for the Par Pond hydrologic system was established in order to estimate the rate of groundwater influx to Par Pond. This estimate will be used in modeling exercises to predict Par Pond reservoir elevation and spillway discharge in the scenario where Savannah River water is no longer pumped and discharged into Par Pond. The principal of conservation of mass was used to develop the water budget, where water inflow was set equal to water outflow. Components of the water budget were identified, and the flux associated with each was determined. The water budget was considered balanced when inflow and outflow summed to zero. The results of this study suggest that Par Pond gains water from the groundwater system in the upper reaches of the reservoir, but looses water to the groundwater system near the dam. The rate of flux of groundwater from the water table aquifer into Par Pond was determined to be 13 cfs. The rate of flux from Par Pond to the water table aquifer near the dam was determined to be 7 cfs

    As former head of AB Operations, Paul Collier and his group were in the ‘cockpit’ for the LHC’s maiden voyage - piloting the first beam around the ring. But now, as Head of the Beams Department, he will need his feet firmly on the ground in order to balance all the beam activities at CERN. "As Department Head, I’ll have less direct contact with the machines," Collier says with a hint of regret. "I’ll still obviously be very involved, but they won’t actually let me loose in front of the keyboard anymore!" As the new Head of the BE Department, Collier will be in charge of nearly 400 people, and will oversee all the beam activities, including the preparations for the longest period of beam operation in the history of CERN. In the new organization, the BE, TE and EN Departments have been grouped together in the Accelerator and Technology Sector. "‘Partnership’ is a key word for the three departments," says Collier.

  3. A balanced memory network.

    2007-09-01

    Full Text Available A fundamental problem in neuroscience is understanding how working memory--the ability to store information at intermediate timescales, like tens of seconds--is implemented in realistic neuronal networks. The most likely candidate mechanism is the attractor network, and a great deal of effort has gone toward investigating it theoretically. Yet, despite almost a quarter century of intense work, attractor networks are not fully understood. In particular, there are still two unanswered questions. First, how is it that attractor networks exhibit irregular firing, as is observed experimentally during working memory tasks? And second, how many memories can be stored under biologically realistic conditions? Here we answer both questions by studying an attractor neural network in which inhibition and excitation balance each other. Using mean-field analysis, we derive a three-variable description of attractor networks. From this description it follows that irregular firing can exist only if the number of neurons involved in a memory is large. The same mean-field analysis also shows that the number of memories that can be stored in a network scales with the number of excitatory connections, a result that has been suggested for simple models but never shown for realistic ones. Both of these predictions are verified using simulations with large networks of spiking neurons.

    Over the course of her career as a physicist, Felicitas Pauss, currently responsible for CERN's External Relations, has often been the sole woman in an environment dominated by men. While she freely admits that being a woman physicist can have as many advantages as disadvantages, she thinks the best strategy is to maintain the right balance.   From a very early age, Felicitas Pauss always wanted to be involved in projects that interested and fascinated her. That's how she came to study physics. When she was a first-year university student in Austria in 1970, it was still fairly uncommon for women to go into physics research. "I grew up in Salzburg with a background in music. At that time, it was certainly considered more ‘normal’ for a woman to study music than to do research in physics. But already in high school I was interested in physics and technical instruments and wanted to know how things work and what they are made of”. At the beginning of her care...

    1990-01-01

    Rising carbon dioxide and global temperatures are causing increasing worldwide concern, and pressure towards an international law of the atmosphere is rapidly escalating, yet widespread misconceptions about the greenhouse effect's inevitability, time scale, and causes have inhibited effective consensus and action. Observations from Antarctic ice cores, Amazonian rain forests, and Carribean coral reefs suggest that the biological effects of climate change may be more severe than climate models predict. Efforts to limit emissions from fossil-fuel combustion alone are incapable of stabilizing levels of carbon dioxide in the atmosphere. Stabilizing atmospheric carbon dioxide requires coupled measures to balance sources and sinks of the gas, and will only be viable with large-scale investments in increased sustainable productivity on degraded tropical soils, and in long-term research on renewable energy and biomass product development in the developing countries. A mechanism is outlined which directly links fossil-fuel combustion sources of carbon dioxide to removal via increasing biotic productivity and storage. A preliminary cost-benefit analysis suggests that such measures are very affordable, costing far less than inaction. (With 88 refs.).

Angelberga rivestì un importante ruolo politico sia durante il suo matrimonio, sia dopo la morte del marito, e riuscì inoltre a costruire un impressionante patrimonio. Angelberga acquisì infatti un grande numero di beni fondiari, in parte tramite donazioni del consorte e in parte grazie ad acquisizioni personali. Nell’877 l’imperatrice assegnò il suo patrimonio al monastero di San Sisto, da lei fondato a Piacenza. Il contributo esamina in dettaglio l’ubicazione dei beni di Angelberga, dimostrando che gran parte di tali beni era situata in prossimità del corso del fiume Po: tale collocazione consentiva il controllo delle principali vie di comunicazione del regno d’Italia. Inoltre le proprietà di Angelberga si trovavano per lo più in aree controllate dai Supponidi, la potente famiglia di origine dell’imperatrice. Il saggio conclude che la costruzione del patrimonio di Angelberga, e del monastero che ne derivò, dimostra una convergenza di interessi economici e politici tra il potere regio e le aristocrazie locali rappresentate dalla potente famiglia d’origine dell’imperatrice.

Angelberga gathered a great number of landed properties, partly through donations from her husband and partly thanks to personal acquisitions. In 877 the empress left her wealth to the monastery of St. Sisto, which she had founded in Piacenza. This article offers a detailed analysis of the location of Angelberga’s properties, showing that most of these properties were situated in the proximity of the Po river: this location allowed for the control of the main communication routes of the Italic Kingdom.

    Full Text Available Sostanziale, reale, la parità di genere è un valore universale, principio e diritto uma-no, proclamato ed imposto da strumenti vincolanti a livello internazionale ed europeo, che ne richiedono l‟effettiva promozione in tutti i campi, stabiliscono il carattere univer-sale e non negoziabile dei diritti umani, inclusa la parità di genere e i diritti delle donne, ed escludono nel modo più assoluto che si possano invocare usanze o tradizioni etniche, culturali o religiose per ostacolarne l‟esercizio. Questo contributo ricorda la ricchezza e i limiti di questo «acquis» internazionale ed europeo in materia di parità di genere, oggi messa seriamente a rischio, sottolineando, a tal proposito, la recente mobilitazione del movimento delle donne e della società civile. L‟attenzione è posta sul diffondersi del re-lativismo culturale, sul sorgere del fondamentalismo religioso e sui tentativi in costante aumento e spesso violenti di distruggere i principi democratici e il ruolo della legge, che si manifestano a livello internazionale, europeo, nazionale e locale, minacciando l‟uguale godimento dei diritti umani da parte delle donne e degli uomini, delle ragazze e dei ragazzi; la propensione ad adottare misure di governance economica di carattere e-sclusivamente monetarista e ad ignorare la dimensione sociale della crisi economica e finanziaria globale, in crescita anche in Europa, a discapito della coesione sociale e del-la crescita. Il contributo sostiene l‟urgente richiesta della società civile che tutti gli attori della comunità internazionale si oppongano con forza a queste tendenze e tentativi, e adottino un‟agenda anti-crisi che sia giusta socialmente e rispettosa dei diritti fonda-mentali, specialmente dei diritti delle donne, così che l‟acquisizione universale nei dirit-ti umani sia salvaguardata e si promuova l‟applicazione degli strumenti sopraindicati.

    Full Text Available The tendency of continuous compounding of business processes inevitably leads to application of increasingly complex instruments for the purposes of financial reporting in agribusiness. In this system the existential place and role of individual elements that alter the existing and acquire new functions comes into question. Balancing implies a regulated and consistent system in which every change leads to the creation of new relations and changing already established relationships. In this regard, in this paper we will focus on the place and role of tax balance in the group of special balances in agribusiness, as a very significant group of accounting instruments. Displaying information for users and situations in which they are used, balances gain their place in this classification. For the purposes of applying financial instruments, referring primarily to balances in agribusiness, it is necessary to know the way of their classification according to their functions. From this aspect, tax balance in agribusiness is a specific report, both in terms of its formal and material structure, which gives it the basis to belong to ordinary as well as special types of balances in agribusiness.

  16. A question of balance: Kinetic balance for electrons and positrons

    International Nuclear Information System (INIS)

    Dyall, Kenneth G.

    2012-01-01

    Graphical abstract: Kinetic balance for both electrons and positrons is achieved by applying the correct relation for positive and negative energy states separately and then using the electron and positron eigensolutions from the separate diagonalizations of the Hamiltonian as a dual basis. Highlights: ► Kinetic balance for electrons and positrons is achieved in a dual atomic basis. ► Dual atomic balance alleviates, but does not eliminate, energy prolapse. ► Positron affinities converge quicker with basis set size with dual atomic balance. - Abstract: The kinetic balance criterion used in current relativistic basis set codes is satisfied by the electron solutions of the Dirac equation, but not the positron solutions. A proposal for applying kinetic balance to both sets of solutions is presented. The method is applied along with “normal” kinetic balance to one-electron systems, to investigate its possible relation to prolapse, and to the positron affinity of F − , to investigate the kinetic energy deficiency for positron solutions. The new method reduces but does not eliminate prolapse for energy-optimized basis sets, and provides faster and smoother convergence with basis set size for the positron affinity.

    The concept and difficulties of work-life balance are not unique to surgeons, but professional responsibilities make maintaining a work-life balance difficult. Consequences of being exclusively career focused include burn out, physical, and mental ailments. In addition, physician burn out may hinder optimal patient care and incur significant costs on health care in general. Assessing current uses of time, allocating goals catered to an individual surgeon, and continual self-assessment may help balance time, and ideally will help prevent burn out.

  19. Modern rotor balancing - Emerging technologies

    Science.gov (United States)

    Zorzi, E. S.; Von Pragenau, G. L.

    1985-01-01

    Modern balancing methods for flexible and rigid rotors are explored. Rigid rotor balancing is performed at several hundred rpm, well below the first bending mode of the shaft. High speed balancing is necessary when the nominal rotational speed is higher than the first bending mode. Both methods introduce weights which will produce rotor responses at given speeds that will be exactly out of phase with the responses of an unbalanced rotor. Modal balancing seeks to add weights which will leave other rotor modes unaffected. Also, influence coefficients can be determined by trial and error addition of weights and recording of their effects on vibration at speeds of interest. The latter method is useful for balancing rotors at other than critical speeds and for performing unified balancing beginning with the first critical speed. Finally, low-speed flexible balancing permits low-speed tests and adjustments of rotor assemblies which will not be accessible when operating in their high-speed functional configuration. The method was developed for the high pressure liquid oxygen turbopumps for the Shuttle.

    pleasure of eating it. The latter, which is similar to food reward, is determined primarily by the state of emptiness of the gut and food liking related to the food's sensory qualities and macronutrient value and the individual's dietary history. Importantly, energy density adds value because energy dense foods are less satiating kJ for kJ and satiation limits further intake. That is, energy dense foods promote energy intake by virtue (1) of being more attractive and (2) having low satiating capacity kJ for kJ, and (1) is partly a consequence of (2). Energy storage is adapted to feast and famine and that includes unevenness over time of the costs of obtaining and ingesting food compared with engaging in other activities. However, in very low-cost food environments with energy dense foods readily available, risk of obesity is high. This risk can be and is mitigated by dietary restraint, which in its simplest form could mean missing the occasional meal. Another strategy we discuss is the energy dilution achieved by replacing some sugar in the diet with low-calorie sweeteners. Perhaps as or more significant, though, is that belief in short-term energy balancing (the energy depletion model) may undermine attempts to eat less. Therefore, correcting narratives of eating to be consistent with biological reality could also assist with weight control. Copyright © 2016 The Authors. Published by Elsevier Inc.

    The energy balances of the Danish Statistical Office are the designation of the goods balances, which are tabulated for each energy article in both physical entities (quantities) and in base rates (values). The balance concept is connected to the definition supply = use, which is the basis for the construction of the system. The supply is determined as the sum of two items: import and production while the total use is the sum of 138 items: export, waste and transmission loss, stock increase, input in lack of the 130 industries, and private consumption divided into 5 consumption groups. The statistical analysis is performed yearly in both quantities and values for 35 energy articles. Values are computed for base rates, profits, taxes, VAT and market prices (buyer's price), respectively. The energy balances from 1975 to 1998 are presented for comparison. (EHS)

    In 1988, a special Committee of the Rocky Mountain Mineral Law Foundation undertook a project to draft a model from gas balancing agreement. This project was initiated at the request of a number of Foundation members who felt that a model form gas balancing agreement would facilitate the negotiation of operating agreement, since gas balancing issues had become sticking points in the process. The Committee was composed of attorneys representing a wide cross-section of the oil and gas industry including both major and independent oil companies, production companies with interstate pipeline affiliates, and private practitioners. The Committee attempted to address the more controversial issues in gas balancing with optional provisions in the Form. To facilitate the negotiation process, the number of optional provisions was minimized. This form may be used as an Appendix to the new A.A.P.L. Form 610-1989 Model Form Operating Agreement. This book includes provision of this Form which are: Ownership of gas production; Balancing of production accounts; Cash balancing upon depletion; Deliverability tests; Nominations; Statements; Payment of taxes; Operating expenses; Overproducing allowable; Payment of leasehold burdens; Operator's liability; Successors and assigns; Audits; Arbitration; and Operator's fees

The goal is to identify the specificity of the educational and social role the Yaquim women play in their community. To this end, we tried to explore their everyday life, to grasp, in the fabric of real life, the salient signs of a symbolic world of great formative significance.The epistemological framework refers to an interpretative pedagogy and thus to a hermeneutical approach. The inquiry methodology, of qualitative kind, is intended as a normative epistemology and implies a systemic perspective.The people involved were informed of the purposes of our conversation and have committed themselves to cooperate in a common project of valorisation and divulgation of the yaqui culture, therefore they have not asked nor received any compensation.

    Full Text Available Infectious diseases continue to represent an important preventive and clinical problem especially in the light of the emergence of new pathogens, of the return of infrequent pathogens and of the increased risk of infective pathologies associated with migratory flow. Another critical point is represented by the possible insurgence of infections due to agents used in bioterrorism. More than ever it is indispensable for our country to define a network of structures able to give an organized response to these relevant problems both in terms of prevention and assistance. It is therefore important to define a protocol for clinical microbiology on a national basis that responds to different levels of activity. Keeping in mind that the fundamental objectives of microbiology are: - diagnosis of infective diseases - determination of resistance to antimicrobic drugs as a valid instrument to allow the clinician to proceed with specific treatment - control of infection spreading in the sanitary structures (hospital infections - to develop front line defence in new infections and bioterrorism, in collaboration with the department of prevention - to be a reference centre for specific training The principals on which one must base the reorganization are essentially three: 1. to configurate the microbiology service on the basis of real needs of the local population 2. to give qualitatively optimal results in real time 3. supporting “good clinical practice” to assure adequate patient results and acceptable costs for the regionale sanitary system (SSR The organization of microbiology should therefore foresee a microbiology department, structured on a provincial basis or a vast area including a structured centralized complex with peripheral structures (even simplified. This must integrate actively with the department of prevention in regard to the dynamics of infectious diseases in the territory and with the Division of Infectious Diseases (where this exists. In parallel an active interaction with research structures (IRCCS and University present in the territory to enable the coordinated implementation of the guidelines of research and its relapse on diagnostic exams. Keeping in mind that the quality of diagnostic performance is closely linked to the professional experience of the operators it is good practice centralizing some diagnostic procedures by identifying a reference centre. In a regional network organized in this way it is important to include a coordinating structure, since it is necessary to activate a complete level of communication, information exchange, activity planning, and complete problem solving.

  18. Alemania siglo XXI: un balance

    Martha Lucía Quiroga Riviere

    2009-11-01

    Full Text Available Veinte años han pasado desde que se dieron los sucesos en la República Democrática Alemana (RDA que llevarían, en noviembre de 1989, a la caída del muro de Berlín y a la reunificación de Alemania el 3 de octubre de 1990. El proceso de unificación alemana dio pie en sus comienzos a una optimista visión que, sin embargo, con el paso del tiempo ha cambiado de tal forma que hoy se habla del ‘messogiorno alemán’ para designar a la zona oriental comparándola con la zona deprimida del sur de Italia. Pero la Alemania unificada en el contexto internacional supuso también cambios para la zona occidental que, entre otros, se han traducido en la crisis del sector industrial tradicional y en el desempleo estructural. Así, a la difícil constelación de la situación interna de la Alemania reunificada, se ha adicionado la realidad internacional con una decreciente producción industrial como fenómeno global en todas las viejas naciones industriales y con un proceso de desregularización que significó en Alemania oriental la ‘privatización de toda la sociedad’. En Alemania se han llevado y se están llevando cambios sociales profundos, que no tienen comparación con ningún otro país de las potencias occidentales ni, en el caso de la ex RDA con ningún país del este. Evaluar el proceso de unificación alemana, primera potencia europea y motor del proceso de integración en ese continente, se hace imperante. El presente artículo intenta hacer un diagnóstico parcial de la nueva realidad en la Alemania unificadaa comienzos del siglo XXI.

This solution allows decentralized mode of operation and the aim of this work is implementation of controlling and diagnostic mechanism into an electric scooter project realized at Technical university of Ostrava. In todays world which now fully enjoys the prime of electromobility, off-grid battery systems and other, it is important to seek the optimal balance between functionality and the economy side of BMS that being electronics which deals with secondary cells of batery packs. There were numerous sophisticated, but not too practical BMS models in the past, such as centralized system or standalone balance modules of individual cells. This article aims at development of standalone balance modules which are able to communicate with the coordinator, adjust their parameters and ensure their cells safety in case of a communication failure. With the current worldwide cutting cost trend in mind, the emphasis was put on the lowest price possible for individual component. The article is divided into two major categories, the first one being desing of power electronics with emphasis on quality, safety (cooling) and also cost. The second part describes development of a communication interface with reliability and cost in mind. The article contains numerous graphs from practical measurements. The outcome of the work and its possible future is defined in the conclusion.

    Full Text Available Since regaining independence in 1990 and creating its regular armed forces, Lithuania has had to do a balancing act. It has had to balance between different approaches of state defence, military structure, collective and national defence. Due to events in Ukraine Lithuania had to reconfigure this balance. The Russian threat forced to emphasize strategy of territorial defence, which altogether required tying up forces and enlarging its numbers by bringing back conscription, substantially increased defence budget, followed by higher tempo and scale in procurement and training. However, Lithuania has managed to maintain its activity and participation in international military operations and political initiatives. Its recent contributions have led to an assumption that its participation in various military missions in the future will not diminish, quite the opposite. Increasing the framework of cooperation in terms of defence and security initiatives will involve Lithuania more deeply and will require further contributions.

    High protein diets affect energy balance beneficially through decreased hunger, enhanced satiety and increased energy expenditure. Dairy products are a major source of protein. Dairy proteins are comprised of two classes, casein (80%) and whey proteins (20%), which are both of high quality......, but casein is absorbed slowly and whey is absorbed rapidly. The present PhD study investigated the effects of total dairy proteins, whey, and casein, on energy balance and the mechanisms behind any differences in the effects of the specific proteins. The results do not support the hypothesis that dairy...... proteins, whey or casein are more beneficial than other protein sources in the regulation of energy balance, and suggest that dairy proteins, whey or casein seem to play only a minor role, if any, in the prevention and treatment of obesity....

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

    This book raises pointed questions about nuclear saber rattling. More than a dozen cases since the bombing of Hiroshima and Magasaki in which some sort of nuclear threat was used as a sparring technique in tense confrontations are cited. Each incident is described and analyzed. Two theories offered to explain America's use of nuclear threats, the balance of interest theory and the balance of power theory, are contrasted throughout the book. This book helps to fill the gap in the understanding of nuclear weapons and their uses, while pointing out that nuclear bravado could lead to an unintended unleashing of these weapons

    Recently, a continuous dynamics was proposed to simulate dynamics of interpersonal relations in a society represented by a fully connected graph. The final state of such a society was found to be identical with the so-called Heider balance (HB), where the society is divided into two mutually hostile groups. In the continuous model, a polarization of opinions was found in HB. Here we demonstrate that the polarization occurs also in Barabási-Albert networks, where the Heider balance is not necessarily present. In the second part of this work we demonstrate the results of our formalism, when applied to reference examples: the Southern women and the Zachary club.

    Control of balance is complex and involves maintaining postures, facilitating movement, and recovering equilibrium. Balance control consists of controlling the body center of mass over its limits of stability. Clinical balance assessment can help assess fall risk and/or determine the underlying reasons for balance disorders. Most functional balance assessment scales assess fall risk and the need for balance rehabilitation but do not differentiate types of balance deficits. A system approach t...

  14. A practical approach to flexible rotor balancing

    International Nuclear Information System (INIS)

    Khan, M.I.; Chohan, G.Y.; Khan, M.Z.

    2001-01-01

    There are various conventional methods for flexible rotor balancing. These :methods have been applied successfully for balancing cylindrical rotors since long. One of these mostly used is modal balancing. Besides its usefulness, difficulties are encountered when sufficient number of balancing planes are not available under certain conditions where a rotor is enclosed at its both ends by discs. In this work, a practical technique of counter balancing has been introduced. This technique has proved its importance in balancing the rotors. We would discuss efficiency of this technique over the conventional modal balancing. (author)

    In karate, balance control represents a key performance determinant. With the hypothesis that high-level athletes display advanced balance abilities, the purpose of the current study was to quantitatively investigate the motor strategies adopted by elite and non-elite karateka to maintain balance control in competition. The execution of traditional karate techniques (kihon) in two groups of elite Masters (n = 6, 31 ± 19 years) and non-elite Practitioners (n = 4, 25 ± 9 years) was compared assessing body center of mass (CoM) kinematics and other relevant parameters like step width and angular joint behavior. In the considered kihon sequence, normalized average CoM height was 8% lower (p < 0.05), while CoM displacement in the horizontal direction was significantly higher in Masters than in Practitioners (2.5 vs. 1.9 m, p < 0.05), as well as CoM average velocity and rms acceleration (p < 0.05). Step width was higher in Masters in more than half of the sequence steps (p < 0.05). Results suggest that elite karateka showed a refined dynamic balance control, obtained through the increase of the base of support and different maneuvers of lower limbs. The proposed method could be used to objectively detect talented karateka, to measure proficiency level and to assess training effectiveness. Copyright © 2015 Elsevier Ltd. All rights reserved.

    performance indicators have higher values. [Italian] I sistemi di supporto alle decisioni che fanno uso di tecniche di analisi multicriterio sono strumenti che, adattandosi ai vari problemi, affiancano il decisore senza sostituirlo, assistendolo nella formulazione del problema, suggerendo e confrontando soluzioni alternative, scartando quelle inefficienti. per valutare la scelta tra due ipotesi alternative di gestione dei rifiuti solidi urbani e' stato applicato al caso di Trento un modello di supporto alle decisioni denominato AHP (Analytic Hierarchy Process), ampiamente utilizzato nella valutazione del ciclo di vita dei prodotti (LCA). Il metodo consente di evidenziare la soluzione che, tra piu' alternative rispetta maggiormente la scala di priorita' definita dal decisore, mantenendo quindi la maggior coerenza possibile tra le premesse e gli obiettivi. Il modello ha messo a confronto due sistemi integrati di smaltimento dei rifiuti per il Trentino. Una soluzione basata sullo schema del Piano Provinciale di smaltimento dei rifiuti del 1997 in cui la discarica ha ancora un ruolo di primo ordine, ed una soluzione alternativa che attribuisce un ruolo centrale alla termodistruzione. Ilmodello ha integrato contemporaneamente tutti gli indicatori (economici, ambientali, energetici e prestazionali), e ha consentito di identificare come soluzione migliore, l'ipotesi alternativa. I vantaggi ambientali, energetici e di prestazione (maggiore recupero di energia e materiali, maggiore autonomia di smaltimento garantita dal sistema e minore impatto tossicologico) conseguibili con la seconda ipotesi, opportunamente pesati, possono orientare il decisore verso una scelta non dettata da sole motivazioni di ordine economico, ma che tenga conto delle esternalita' incluse nella valutazione.

    Full Text Available Las ligas deportivas dependen del equilibrio competitivo entre los equipos para ser atractivas para los espectadores, de ahí la aparición del balance competitivo. Por ello, las distintas ligas deportivas han adquirido diferentes formatos que determinarán su competitividad. El objetivo de este artículo es comparar el balance competitivo de la NBA y las principales ligas europeas, teniendo en cuenta la NBA en su conjunto y cada una de sus conferencias de forma independiente. Las variables utilizadas para medir el balance competitivo han sido el índice Hirschman-Herfindal y las ratios C5 y C8. Los resultados muestran un mejor balance competitivo de la NBA en conjunto respecto a las ligas europeas, sin embargo estas diferencias desaparecen al analizar las conferencias de forma independiente. Se concluye que al tener en cuenta cada una de las conferencias de forma independiente, con una estructura más similar a las ligas europeas, se presenta un balance competitivo parecido bajo los indicadores utilizados. Sin embargo, la NBA incluye limitaciones en la competición que siguen favoreciendo la posibilidad de que sea más atractiva para el espectador.

Seven groups of Wistar rats were used. One group was killed on the first experimental day being utilized as control of initial body copper content. Six groups of rats were fed, over 15 days, semipurified diets varying only in the fat level, three of them containing 8% of fat, and the other three 2%. The overall copper balance was studied by calculating differences between the initial and final body copper content. During the last week, another copper balance was carried out by monitoring intake and faecal copper excretion. Body mass, and liver, spleen, skin, erythrocytes and serum copper contents were also examined. The copper utilization was lower in 2% fat rats, this was caused by food intake decrease but also by the lower copper bioavailability in 2% fat diets. The corporal, liver and spleen copper contents were reduced, and liver, skin and serum copper concentrations also decreased in the rats fed on 2% fat diets. Palm olein (8% versus olive and sunflower oil produced a lower efficiency of copper absorption.

    Balancing the personal and the professional is an ongoing struggle for most professionals, and palliative care clinicians are no exception. A sustained lack of balance can lead to feelings of frustration, inadequacy, and guilt. Palliative care physicians may find this balance particularly difficult due to the nature of their work: caring for patients and families who are often suffering and in crisis. In this article, we describe challenges to work-life balancing and strategies that may promote balance, including "timeshifting," goal setting, cognitive reframing, and self-care. We argue that the search for balance is a lifelong endeavor that entails self-reflection and continuing examination of one's values and goals.

    A gerotor pump for pressurizing gasoline fuel is capable of developing pressures up to 2.0 MPa with good mechanical and volumetric efficiency and satisfying the durability requirements for an automotive fuel pump. The pump has been designed with optimized clearances and by including features that promote the formation of lubricating films of pressurized fuel. Features of the improved pump include the use of a shadow port in the side plate opposite the outlet port to promote balancing of high fuel pressures on the opposite sides of the rotors. Inner and outer rotors have predetermined side clearances with the clearances of the outer rotor being greater than those of the inner rotor in order to promote fuel pressure balance on the sides of the outer rotor. Support of the inner rotor and a drive shaft on a single bushing with bearing sleeves maintains concentricity. Additional features are disclosed.

    As recently dictated by the American Medical Society, balance testing is an important component in the clinical evaluation of concussion. Despite this, previous research on the efficacy of balance testing for concussion diagnosis suggests low sensitivity (∼30%), based primarily on the popular Balance Error Scoring System (BESS). The Balance Tracking System (BTrackS, Balance Tracking Systems Inc., San Diego, CA, USA) consists of a force plate (BTrackS Balance Plate) and software (BTrackS Sport Balance) which can quickly (balance testing with gold standard accuracy. The present study aimed to determine the sensitivity of the BTrackS Balance Plate and Sports Balance Software for concussion diagnosis. Cross-Sectional Study. Preseason baseline balance testing of 519 healthy Division I college athletes playing sports with a relatively high risk for concussions was performed with the BTrackS Balance Test. Testing was administered by certified athletic training staff using the BTrackS Balance Plate and Sport Balance software. Of the baselined athletes, 25 later experienced a concussion during the ensuing sport season. Post-injury balance testing was performed on these concussed athletes within 48 of injury and the sensitivity of the BTrackS Balance Plate and Sport Balance software was estimated based on the number of athletes showing a balance decline according to the criteria specified in the Sport Balance software. This criteria is based on the minimal detectable change statistic with a 90% confidence level (i.e. 90% specificity). Of 25 athletes who experienced concussions, 16 had balance declines relative to baseline testing results according to the BTrackS Sport Balance software criteria. This corresponds to an estimated concussion sensitivity of 64%, which is twice as great as that reported previously for the BESS. The BTrackS Balance Plate and Sport Balance software has the greatest concussion sensitivity of any balance testing instrument reported to date. Level 2

  14. Towards balanced development in Pakistan.

    Pyatt, G

    1992-01-01

    Pakistan is a country whose economic growth is surprising in light of its social indicators. The aim of this article is to examine why conditions are such and to develop a framework for understanding the issues as an aid to redesigning policies. 5 sections are devoted to a summary of the main findings, the diagnosis of development and the impact on social sectors, a proposal for balanced development, and implications for policy changes. A sound macro economic context is needed with reforms economically in price and incentive systems, institutionally, and in the law and order sector. Public administration needs to be improved and individual opportunities need to be expanded. Internal security needs to be secured, so that law and order are restored. Economic growth has been high between 1960 and 1988, due to exploitation of natural resources and cheap unskilled labor, expansion of irrigated land, and growth of the unregulated informal sector. The major constraints on economic growth will come from a lack of fiscal discipline. 40% of government revenues are consumed by the military and 20% for servicing debt. Other constraints are the population growth rate in excess of 3%/year, an urban bias in allocation of resources, neglected primary education, and gender bias in education. There has been little incentive for provincial governments to balance budgets, and civil service has become disorganized. Balanced development entails recognizing human capital, natural resources, and infrastructure; accepting the status quo; and creating and maintaining an institutional framework to correct market failures and promote individual opportunities. The environmental polluter must pay. Income must be increased through higher wages, increasing the demand for labor, and transfers to households in the form of food rations, schooling, and medical care. Investment in women will increase household earnings, and improve living conditions and the health of themselves and their children

    The principles of balance, randomization, control and repetition, which are closely related, constitute the four principles of scientific research. The balance principle is the kernel of the four principles which runs through the other three. However, in scientific research, the balance principle is always overlooked. If the balance principle is not well performed, the research conclusion is easy to be denied, which may lead to the failure of the whole research. Therefore, it is essential to have a good command of the balance principle in scientific research. This article stresses the definition and function of the balance principle, the strategies and detailed measures to improve balance in scientific research, and the analysis of the common mistakes involving the use of the balance principle in scientific research.

    to determine whether it is the presence of women in an organization or the presence of working parents that induce organizations to implement work-family balancing and ORWT measures. We found that workers without children are more often found in jobs that offer more services for the elderly and for childcare. We also show that regarding ORWT, behaviours of women without children are often closer to those of men, but that the presence of children is a major factor in explaining the aspirations of men regarding working time. Few studies have investigated these issues from this angle and it is clear that the presence of children is often more of a determining factor than the fact of being a woman, while women are still clearly more concerned when daycare services or care for the elderly are involved.Los datos que presentaremos proporcionan un retrato de la situación canadiense desde el punto de vista de la organización y de la reducción del tiempo de trabajo (ORTT, así como del lugar de trabajo (oficina, domicilio, etc.. Los datos muestran en qué medida el ORTT puede ser visto por algunos como una solución y por otros como una fuente de dificultades para los problemas de conciliación entre el empleo y la familia o de estrés. Hemos estudiado la situación tanto de los hombres como de las mujeres en situación de empleo y hemos preguntado si la presencia de las mujeres dentro de una organización o la de padres de familia trabajadores incita a las organizaciones a instaurar medidas de conciliación y de ORTT. Es interesante constatar que las personas sin hijos ocupan más frecuentemente empleos que ofrecen mayores servicios para personas de edad avanzada y para la guardería de niños. En lo que a la ORTT se refiere, mostramos que los comportamientos de las mujeres sin hijos se asemejan a los de los hombres, pero que la presencia de hijos es un factor fundamental para explicar las aspiraciones de los hombres en cuanto al tiempo de trabajo.

    2013-01-01

    Full Text Available Developmental endothelial locus-1 (Del-1 is an endothelial cell-secreted protein that limits the recruitment of neutrophils by antagonizing the interaction between the LFA-1 integrin on neutrophils and the intercellular adhesion molecule (ICAM-1 on endothelial cells. Mice with genetic or age-associated Del-1 deficiency exhibit increased neutrophil infiltration in the periodontium resulting in inflammatory bone loss. Here we investigated additional novel mechanisms whereby Del-1 could interfere with neutrophil recruitment and inflammation. Treatment of human endothelial cells with Del-1 did not affect the expression of endothelial molecules involved in the leukocyte adhesion cascade (ICAM-1, VCAM-1, and E-selectin. Moreover, genetic or age-associated Del-1 deficiency did not significantly alter the expression of these adhesion molecules in the murine periodontium, further ruling out altered adhesion molecule expression as a mechanism whereby Del-1 regulates leukocyte recruitment. Strikingly, Del-1 inhibited ICAM-1-dependent chemokine release (CXCL2, CCL3 by neutrophils. Therefore, Del-1 could potentially suppress the amplification of inflammatory cell recruitment mediated through chemokine release by infiltrating neutrophils. Interestingly, Del-1 was itself regulated by inflammatory stimuli, which generally exerted opposite effects on adhesion molecule expression. The reciprocal regulation between Del-1 and inflammation may contribute to optimally balance the protective and the potentially harmful effects of inflammatory cell recruitment.

    La doctora MarthaLucía Tamayo comparte muchas inquietudes alrededor del Libro del Almismo, el Libro del Pensar; de dónde salió ese nombre; de juntar en medicina y en genética a tres escritores como lo son Jorge Luis Borges, Macedonio Fernández y Julio Cortázar. Su conferencia dice así:

    El término almismo fue ideado por Macedonio Fernández porque defendía mucho el ensimismamiento y el pensamiento hacia el interior, mirar hacia adentro; cada uno somos un “sí mismo” que nos hace diferentes aunque al mismo tiempo podemos ser iguales. Todos tenemos esa parte interior que la medicina debe trabajar y que no puede olvidar.

    “El Libro del Almismo, el libro del pensar” nos lleva a replantear y a repensar un poco la medicina que queremos, una medicina vuelta a pensar.

    Quiero contarles la historia de cómo se llegó a este libro y por qué y para qué se sigue trabajando en estos temas: Después de mi internado y de un trabajo un poco triste de rural, volví al Instituto de Genética y a la Universidad Javeriana en donde encontré al doctor Bernal y un espacio que estaba buscando para esa medicina diferente que quería, con un grupo de personas que me permitía no sólo ver la medicina sino ver muchas otras cosas más; había espacio para la literatura, para Mafalda, para hablar de niños, de locos, había incluso tiempo para hablar de medicina dentro del golf, de carros antiguos y de todo eso fui aprendiendo.

    Eso era lo que estaba buscando. Una medicina que diera espacios diferentes, que fuera más humanizada. Rápidamente me ubiqué y me quedé! No me arrepiento en lo absoluto de haberme quedado porque fue, ha sido y sigue siendo, una experiencia enriquecedora, de muchas vivencias importantes. Sabía exactamente dónde estaba y sabía que había que seguir rápido y había que trabajar muchos aspectos de esa medicina que estábamos buscando y de esa genética especial.

    Background: A good body balance requires a proper function of vestibular, visual, and somatosensory systems which can be reach with exercise practice and/or yoga. Aim: To determine the effects of a 5-month hatha yoga training program on body balance in young adults. Materials and Methods: This study used a controlled, nonrandomized design, where the experimental group underwent a 5-month training program and were then compared with the control group that had a sedentary lifestyle. A convenience sample of 34 out of 40 men aged 25-55 years old (34.0 ± 0.9) were deemed eligible for this study. They were randomly divided into two groups: Experimental and control groups. Subjects in the experimental group were engaged in 60 min sessions of hatha yoga three times a week for 5 months. We evaluated postural control by measuring the limit of stability and velocity of oscillation (VOS) in three conditions of the balance rehabilitation unit (BRU) and through field procedures (four position, plane, flamingo, hopscotch, and dynamic test). Results: We observed differences (P < 0.05) in postintervention scores between the groups regardless of BRU parameters and field procedures (except for flamingo) even after adjusting for preintervention scores, suggesting that these changes were induced by hatha yoga training. The partial eta squared on BRU parameters ranged from 0.78 (VOS1)-0.97 (COP2), and from 0.00 (flamingo)-0.94 (four position) for the field procedures. Conclusions: Our results provide substantial evidence that postural control in healthy young adults can be improved through practicing hatha yoga. PMID:25035623

  1. Calcium Balance in Chronic Kidney Disease.

    Hill Gallant, Kathleen M; Spiegel, David M

    2017-06-01

    The kidneys play a critical role in the balance between the internal milieu and external environment. Kidney failure is known to disrupt a number of homeostatic mechanisms that control serum calcium and normal bone metabolism. However, our understanding of calcium balance throughout the stages of chronic kidney disease is limited and the concept of balance itself, especially with a cation as complex as calcium, is often misunderstood. Both negative and positive calcium balance have important implications in patients with chronic kidney disease, where negative balance may increase risk of osteoporosis and fracture and positive balance may increase risk of vascular calcification and cardiovascular events. Here, we examine the state of current knowledge about calcium balance in adults throughout the stages of chronic kidney disease and discuss recommendations for clinical strategies to maintain balance as well as future research needs in this area. Recent calcium balance studies in adult patients with chronic kidney disease show that neutral calcium balance is achieved with calcium intake near the recommended daily allowance. Increases in calcium through diet or supplements cause high positive calcium balance, which may put patients at risk for vascular calcification. However, heterogeneity in calcium balance exists among these patients. Given the available calcium balance data in this population, it appears clinically prudent to aim for recommended calcium intakes around 1000 mg/day to achieve neutral calcium balance and avoid adverse effects of either negative or positive calcium balance. Assessment of patients' dietary calcium intake could further equip clinicians to make individualized recommendations for meeting recommended intakes.

    We model a close-knit community of friends and enemies as a fully connected network with positive and negative signs on its edges. Theories from social psychology suggest that certain sign patterns are more stable than others. This notion of social "balance" allows us to define an energy landscape for such networks. Its structure is complex: numerical experiments reveal a landscape dimpled with local minima of widely varying energy levels. We derive rigorous bounds on the energies of these local minima and prove that they have a modular structure that can be used to classify them.

    Full Text Available We consider log-convex sequences that satisfy an additional constraint imposed on their rate of growth. We call such sequences log-balanced. It is shown that all such sequences satisfy a pair of double inequalities. Sufficient conditions for log-balancedness are given for the case when the sequence satisfies a two- (or more- term linear recurrence. It is shown that many combinatorially interesting sequences belong to this class, and, as a consequence, that the above-mentioned double inequalities are valid for all of them.

  7. Surface energy balance measurements in the Mexico City: a review

    During the last decade of the 20th Century, diverse campaigns for measuring the atmospheric energy balance were performed in downtown Mexico City (School of Mines and Preparatory School No. 7), in the southern suburbs (University Reserve) and in the surrounding rural areas (Plan Texcoco), in addition to a campaign carried out in 1985 in the Tacubaya district, a suburban western peripheral site. The objective was to obtain data for a better understanding of the climatic alterations due to urbanization, particularly to describe the role that the modification of the natural ground cover has played as a result of paving and the construction of urban canyons. In this paper, a review of these campaigns is presented. Energy partitioning in some areas (Tacubaya and Preparatory School No.7) is similar to that observed in urban centers of middle latitudes, whereas the major contrast was observed between Texcoco, with maximum energy consumption through evaporation, and School of Mines, where the latent heat is as low as in a desert. From the values of the correlations among the different components of energy balance, it may be possible to attempt the modeling of the diverse components of energy balance by means of regression equations starting from the net radiation. Those same coefficients distinguish the type of environment: urban, suburban or rural. [Spanish] Las primeras mediciones de balance energetico en la Ciudad de Mexico se realizaron en 1985 en un suburbio al poniente de la ciudad (el observatorio de Tacubaya). Ya en la decada de los anos noventa del siglo XX, dichas observaciones se multiplicaron tanto en el centro historico (antigua Escuela de Minas y en el edificio de la Preparatoria No. 7), como en otros sitios al sur (en terrenos de Ciudad Universitaria) y en la periferia rural (Plan Texcoco). El proposito de estas mediciones ha sido tener un mejor entendimiento de las alteraciones climaticas debidas a la urbanizacion. En este trabajo se presenta una revision

The leaves of tree spinach (Cnidoscolus chayamansa, a bush that grows in Mexico and Central and South America, are one such option. In this work, juvenile tilapia (7-4.5 g survival, growth rates, and food conversion rates were studied during two seasons (warm and cold, substituting 25 and 50% of the balanced feed rations with raw tree spinach leaves (ad libitum. The experimental design was completely random, with two treatments and one control (00% of the balanced feed ration; three replicates were done in each season. The densities were 36 fish m-per replica in the cold season and 44 fish m-3 per replica in the warm season. The weight gain in the treatments with 50 and 75% balanced feed and tree spinach leaves was similar to that of the control group in both seasons. The cold season adversely affected survival, weight gain, and feed conversion rates in all treatments, but the warm season did not. When tree spinach leaves were included in the tilapia diet, the feed conversion rate for the balanced feed was reduced from 9.7 to 33.62% in the cold season and from 5.38 to 40.23% in the warm season. The results show that the use of locally available complementary inputs such as tree spinach leaves may favor the development of small-scale tilapia cultures in the tropics.

    Full Text Available A partir de un texto del poeta Octavio Paz llamado «La imagen», se busca proseguir la equivalencia entre las imágenes de la poesía y la función que ellas tienen para el poeta, y el fantasma fundamental y su función para el analizante que está en el momento del pase. Se parte de la idea de que la poesía busca entrar en el ser así como el psicoanálisis tiene como finalidad apuntar al corazón del ser del sujeto. Se hace entonces una distinción del concepto de «ser» para el psicoanálisis, haciendo alusión también al discurso de la filosofía. Esclarecido el sentido de lo que es el «ser» para el psicoanálisis, se aborda de lleno – entre otras cosas, relacionadas con la experiencia del pase específicamente- la equivalencia entre la definición que hace Octavio Paz de «La Imagen» y el momento del pase en el análisis de un sujeto, imagen que, al igual que el mito para la filosofía, las leyes para la ciencia y el matema para el psicoanálisis, se constituyen en los instrumentos con los que cada una de estas disciplinas horadan en lo real.

    The scientific work within the activity ''ecological/biological balances and conservation'' is summarised in this report. The aims of the activity during its existence between 1992 and 1994 have been to: (i) arrange a workshop and publish the presentations on the environmental aspects of energy forest cultivations, (ii) perform joint scientific work together with the activity group on ''biological disposal of wastewaters and sludges'', that is closely related to environmental problems, and (iii) produce ecological guidelines concerning energy forestry, suitable for advisers and farmers dealing with bioenergy problems. The most important results from the workshop were the environmental benefits from energy forestry when compared with intensive agriculture and forestry. Energy forestry has positive influence on the carbon balances, nutrient recycling, and soil sustainability. The effects are also positive on the natural flora and fauna, which in most cases are enriched when compared with agricultural crops. From the joint efforts of the two activities the main result was a study tour, conference and workshop, concentrating on biological purification systems. The most promising system seems to be the vegetation filters of short rotation coppice. The report on ecological guidelines contains a number of ideas and recommendations for establishment, management, and harvesting of energy forests in an environmentally acceptable way. It also gives advice on how to locate the stands to minimise the risk of nutrient leakage from arable land. (Author)

Se experimentó con la Transformada de Fourier en dos dimensiones, y con la aplicación de filtros de paso alto y bajo. Se encontró que el metodo de "autocorrelación" es el mejor para separar "la vegetación" de "la montaña". Se aplicaron diversas técnicas a fin de cubrir ambos extremos: a) enfatizar detalles débiles en la cola, y b) penetrar en las regiones más intensas de la coma. Se lograron ambos objetivos. Detalles en la cola permitieron determinar velocidades de propagación de unos 50 a 90 kms/ seg. Se pudieron detectar no menos de tres perturbaciones en "Y", y una en 5? Co de Cisne). Se cree que las primeras están asociadas a eventos de desconexión. Se puede separar la cola de gas de la de polvo.

    Health care employees are often women, a group that has high degrees of sick leave and perhaps problems attaining occupational balance. However, people think differently about their everyday activities and it is therefore important to take their perceptions into account but occupational balance has not yet been measured in health professionals. The aim was to describe occupational balance in three different samples of health professionals in Sweden. A further aim was to investigate whether occupational therapists (OTs) rate their occupational balance differently from other health professionals. Four hundred and eighty-two health professionals, employees in public dentistry, mental health care and OTs, aged 21-70 years participated. The participants' occupational balance was measured using the occupational balance questionnaire (OBQ). The ratings of occupational balance were similar to earlier studies and did not differ significantly between the samples. The OTs' occupational balance was also similar to that of the other health professionals. The similarities in occupational balance indicate the same difficulties in attaining it. The result highlights the possibility that working people face similar difficulties in achieving occupational balance. Further research is warranted about how to attain it.

    Mashikian, Matthew S.

    1985-01-01

    A battery plant is described which features magnetic circuit means in association with each of the battery strings in the battery plant for balancing the electrical current flow through the battery strings by equalizing the voltage across each of the battery strings. Each of the magnetic circuit means generally comprises means for sensing the electrical current flow through one of the battery strings, and a saturable reactor having a main winding connected electrically in series with the battery string, a bias winding connected to a source of alternating current and a control winding connected to a variable source of direct current controlled by the sensing means. Each of the battery strings is formed by a plurality of batteries connected electrically in series, and these battery strings are connected electrically in parallel across common bus conductors.

  19. Energy balance of solid biofuels

    International Nuclear Information System (INIS)

    Scholz, V.; Berg, W.; Kaulfuss, P.

    1998-01-01

    The input and output of energy are two important factors used to determine the energetic and ecological usefulness of a fuel or its production technology. In this paper, a number of different methods for the production of five biofuels which can be produced in agriculture and forestry are analysed and energetic balances are presented. The results show that the energetic input is relatively low compared to the output, especially for by-products and residual substances such as cereal straw and forest pruning timber (thinning). Whenever fuel crops are cultivated, the energetic efficiency is critically determined by the quantity of nitrogen applied. Depending on the crop and technology, each gigajoule of energy input can provide 7-30 GJ or with by-products up to 50 GJ of thermally utilizable energy without any additional CO 2 pollution.

    We study the intrinsic geometrical structure of hypersurfaces in six-manifolds carrying a balanced Hermitian SU(3)-structure, which we call balanced SU(2)-structure. We provide sufficient conditions, in terms of suitable evolution equations, which imply that a five-manifold with such structure can be isometrically embedded as a hypersurface in a balanced Hermitian SU(3)-manifold. Any five-dimensional compact nilmanifold has an invariant balanced SU(2)-structure, and we show how some of them can be evolved to give new explicit examples of balanced Hermitian SU(3)-structures. Moreover, for n=3,4, we present examples of compact solvmanifolds endowed with a balanced SU(n)-structure such that the corresponding Bismut connection has holonomy equal to SU(n)

We apply the vertical homotopy decomposition to get a local splitting (in a convenient domain of a general balance system as the sum of a Lagrangian part and a complemental ''pure non-Lagrangian'' balance system. In the case when derivatives of the dynamical fields do not enter the constitutive relations of the balance system, the ''pure non-Lagrangian'' systems coincide with the systems introduced by S. Godunov [Soviet Math. Dokl. 2 (1961, 947-948] and, later, asserted as the canonical hyperbolic form of balance systems in [Müller I., Ruggeri T., Rational extended thermodynamics, 2nd ed., Springer Tracts in Natural Philosophy, Vol. 37, Springer-Verlag, New York, 1998].

    Chen, Xiulai; Li, Shubo; Liu, Liming

    2014-06-01

    Redox balance plays an important role in the production of enzymes, pharmaceuticals, and chemicals. To meet the demands of industrial production, it is desirable that microbes maintain a maximal carbon flux towards target metabolites with no fluctuations in redox. This requires functional cofactor systems that support dynamic homeostasis between different redox states or functional stability in a given redox state. Redox balance can be achieved by improving the self-balance of a cofactor system, regulating the substrate balance of a cofactor system, and engineering the synthetic balance of a cofactor system. This review summarizes how cofactor systems can be manipulated to improve redox balance in microbes. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The torsion balance is a remarkably capable instrument for the measurement of slowly varying exceedingly small forces; indeed its potential abilities are still largely untapped. The author outlines some of the virtues (and limitations) of the torsion balance, and presents a menu of gravitation-related experiments to which it may be applied. He discusses plans for developing torsion balances operating at cryogenic temperatures, and describes an experiment to search for anomalous long-range interactions associated with intrinsic spin.

  16. Competing values in healthcare: balancing the (un)balanced scorecard.

    Science.gov (United States)

    Wicks, Angela M; St Clair, Lynda

    2007-01-01

    Facing a complex environment driven by two decades of dramatic change, healthcare organizations are adopting new strategic frameworks such as the Balanced Scorecard (BSC) to evaluate performance (Kaplan and Norton 1992). The BSC was not originally developed as a performance management tool, however. Rather, it was designed as a tool to communicate strategy and, as such, provides little guidance when actual outcomes fall short of desired outcomes. In addition, although the BSC is an improvement over exclusively financial measures, it has three conceptual limitations that are especially problematic for evaluating healthcare organizations: (1) it underemphasizes the employee perspective, (2) it is founded on a control-based management philosophy, and (3) it emphasizes making trade-offs. To address these limitations, we propose using the Competing Values Framework (CVF), a theoretically grounded, comprehensive approach to understanding and improving organizational and managerial performance by focusing on four action imperatives: competing, controlling, collaborating, and creating. The CVF pays particular attention to the employee perspective, is consistent with a commitment-based management philosophy, and emphasizes transcending apparent paradoxes to identify win-win solutions. Rather than focusing on customer satisfaction or employee satisfaction, the CVF looks for ways to satisfy customers and employees while still addressing financial constraints and growth opportunities. The CVF also can be used to assess both the culture of the organization and the competencies of individual managers, thereby providing a clear link between strategy and implementation.

    Carbon balance is an important instrument to identify the emission sources of greenhouse effect gases. Since energy use and transformation are fundamental for increasing these gases in the atmosphere, the carbon balance survey can be used to identify sectors and fuels to which priority should be given regarding emissions mitigation. In the case of transformation centers (installations where primary or secondary sources are converted into sub-products or other energy form) the balance indicated some problems regarding the Brazilian inventory calculation. Problems concerning the National Energy Balance data used here were also identified. (author)

    1997-01-01

    We present a map of balance velocities for the Greenland ice sheet. The resolution of the underlying DEM, which was derived primarily from radar altimetry data, yields far greater detail than earlier balance velocity estimates for Greenland. The velocity contours reveal in striking detail the location of an ice stream in northeastern Greenland, which was only recently discovered using satellite imagery. Enhanced flow associated with all of the major outlets is clearly visible, although small errors in the source data result in less accurate estimates of the absolute flow speeds. Nevertheless, the balance map is useful for ice-sheet modelling, mass balance studies, and field planning.

  20. Balancing guava nutrition with liming and fertilization

    2012-12-01

    Full Text Available Guava response to liming and fertilization can be monitored by tissue testing. Tissue nutrient signature is often diagnosed against nutrient concentration standards. However, this approach has been criticized for not considering nutrient interactions and to generate numerical biases as a result of data redundancy, scale dependency and non-normal distribution. Techniques of compositional data analysis can control those biases by balancing groups of nutrients, such as those involved in liming and fertilization. The sequentially arranged and orthonormal isometric log ratios (ilr or balances avoid numerical bias inherent to compositional data. The objectives were to relate tissue nutrient balances with the production of "Paluma" guava orchards differentially limed and fertilized, and to adjust the current patterns of nutrient balance with the range of more productive guava trees. It was conducted one experiment of 7-yr of liming and three experiments of 3-yr with N, P and K trials in 'Paluma' orchards on an Oxisol. Plant N, P, K, Ca and Mg were monitored yearly. It was selected the [N, P, K | Ca, Mg], [N, P | K], [N | P] and [Ca | Mg] balances to set apart the effects of liming (Ca-Mg and fertilizers (N-K on macronutrient balances. Liming largely influenced nutrient balances of guava in the Oxisol while fertilization was less influential. The large range of guava yields and nutrient balances allowed defining balance ranges and comparing them with the critical ranges of nutrient concentration values currently used in Brazil and combined into ilr coordinates.

    Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Within limits, market participants can however also resort to the balancing energy market to close their positions. In this paper, we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the German balancing energy demand. We find that those strategies allow an economically optimal starting point for real-time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces. The strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market. (author)

    Wolfram syndrome (WFS), a rare neurodegenerative disorder, is characterized by early onset insulin-dependent diabetes mellitus, optic atrophy, deafness, diabetes insipidus, and neurological abnormalities. Although previously unreported, we hypothesized that neurological complications may be detectable in relatively early stages of the disease. As the cerebellum and brainstem seem particularly vulnerable in WFS, we focused on balance functions critically dependent on these regions. The primary goal of this investigation was to compare balance in young individuals with WFS, in relatively early stages of the disease, to an age-matched cohort using a clinically applicable test. Balance was assessed via the mini-BESTest in 13 children, adolescents and young adults with WFS and 30 typically developing age-matched individuals. A significant difference was observed between groups in balance as well as in three of four subcomponents of the mini-BESTest and in two timed tasks related to balance. Mini-BESTest scores were correlated with age among typically developing individuals. In the WFS group, mini-BESTest scores were related to overall motor dysfunction, but not age. Impairments in balance in WFS may occur earlier in the disease process than previously recognized and appear to be related to overall neurological progression rather than chronological age. Recognizing balance impairments and understanding which balance systems contribute to balance deficits in those with WFS may allow for development of effective patient-centered treatment paradigms.

  14. Balance confidence is related to features of balance and gait in individuals with chronic stroke

    Schinkel-Ivy, Alison; Wong, Jennifer S.; Mansfield, Avril

    2016-01-01

    Reduced balance confidence is associated with impairments in features of balance and gait in individuals with sub-acute stroke. However, an understanding of these relationships in individuals at the chronic stage of stroke recovery is lacking. This study aimed to quantify relationships between balance confidence and specific features of balance and gait in individuals with chronic stroke. Participants completed a balance confidence questionnaire and clinical balance assessment (quiet standing, walking, and reactive stepping) at 6 months post-discharge from inpatient stroke rehabilitation. Regression analyses were performed using balance confidence as a predictor variable and quiet standing, walking, and reactive stepping outcome measures as the dependent variables. Walking velocity was positively correlated with balance confidence, while medio-lateral centre of pressure excursion (quiet standing) and double support time, step width variability, and step time variability (walking) were negatively correlated with balance confidence. This study provides insight into the relationships between balance confidence and balance and gait measures in individuals with chronic stroke, suggesting that individuals with low balance confidence exhibited impaired control of quiet standing as well as walking characteristics associated with cautious gait strategies. Future work should identify the direction of these relationships to inform community-based stroke rehabilitation programs for individuals with chronic stroke, and determine the potential utility of incorporating interventions to improve balance confidence into these programs.

    Professionals working in the arena of health care face a variety of challenges as their careers evolve and develop. In this review, we analyze the role of mentorship, learning curves, and balance in overcoming challenges that all such professionals are likely to encounter. These challenges can exist both in professional and personal life. As any professional involved in health care matures, complex professional skills must be mastered, and new professional skills must be acquired. These skills are both technical and judgmental. In most circumstances, these skills must be learned. In 2007, despite the continued need for obtaining new knowledge and learning new skills, the professional and public tolerance for a "learning curve" is much less than in previous decades. Mentorship is the key to success in these endeavours. The success of mentorship is two-sided, with responsibilities for both the mentor and the mentee. The benefits of this relationship must be bidirectional. It is the responsibility of both the student and the mentor to assure this bidirectional exchange of benefit. This relationship requires time, patience, dedication, and to some degree selflessness. This mentorship will ultimately be the best tool for mastering complex professional skills and maturing through various learning curves. Professional mentorship also requires that mentors identify and explicitly teach their mentees the relational skills and abilities inherent in learning the management of the triad of self, relationships with others, and professional responsibilities.Up to two decades ago, a learning curve was tolerated, and even expected, while professionals involved in healthcare developed the techniques that allowed for the treatment of previously untreatable diseases. Outcomes have now improved to the point that this type of learning curve is no longer acceptable to the public. Still, professionals must learn to perform and develop independence and confidence.

    Full Text Available El presente trabajo resume la historia del deporte deldel. Existen dos versiones sobre el origen deldel. La primera versión relaciona los antecedentes deldel con los de otros deportes de raqueta como el tenis o el bádminton, siendo su origen común el jeu de la paume francés. Posteriormente, surgen variantes en Estados Unidos como el Paddle Tennis y el Platform Tennis, siendo versiones reducidas del tenis, pero con elementos muy comunes al pádel actual. La segunda versión, aprobada por la Federación Internacional de Pádel, afirma que este deporte nació en México, en 1969, a través del empresario Enrique Corcuera.--------------------------------------------------------------------This research summarizes the history of paddle sport. There are two versions about the origin of paddle. The first version relates the history of paddle with other racket sports like tennis or badminton, and its common origin of the Jeu de Paume French. Later, in in the United States, appear two sports called Paddle Tennis and Platform Tennis, which are reduced versions of tennis sport, but these have lot of common characteristics with paddle. The second version, approved by the International Padel Federation, said the sport was born in Mexico in 1969, through the businessman Enrique Corcuera.

  18. Determinantes del ingreso y del gasto corriente de los hogares

    Full Text Available Este ensayo de investigación empírica analiza los determinantes del ingreso y del gasto en los hogares colombianos. Utilizando un modelo del ciclo de vida con datos de la encuesta de hogares de 1994 y 1995, muestra que el comportamiento del ingreso está afectado principalmente por las características demográficas del hogar y los rasgos socio ocupacionales de sus miembros. El comportamiento del gasto está determinado ante todo por el ingreso y, en menor medida, por las características sociales del hogar y el gasto de otros hogares con características similares. También examina la influencia de la incertidumbre acerca de los ingresos en el gasto de los hogares para comprobar si estos actúan con motivos de precaución.

  19. Sustaining a world in balance.

    The world balance of population and resources is the internationally accepted goal for the 20th century. There is agreement that the requirements are elimination of absolute poverty, the legitimate satisfaction of the majority population, reduction in the environmental cost of development, fairer distribution of the benefits of development, slower population growth, and more balanced distribution within and between countries. A profile is given for 15 development and population measures for the Philippines. In the Philippines over 50% of the population lives in poverty, and the numbers are increasing. Unemployment is high at 10.6% in 1991, and underemployment is estimated to be 31.6%. Limited employment opportunities are push factors for international labor migration, which has swelled to over 600,000 workers. The Philippines is losing forest at the rate of about 119,000 hectares per year, which would result in a total loss of forests in 12 years. The loss of biodiversity is apparent. Marine resources are being depleted, and average farm size per rural person is 0.38 hectares. The average family of 6 persons must produce food on only 2.28 hectares. The annual population growth rate is 2.3%, and the rate of food production is only 1%. Metro Manila is now the 18th largest urban area in the world. Air pollution is very high, and the water supply is polluted with salt. 14% of children under 6 years old are severely underweight. Iron deficiency anemia affects 60% of children 1-6 years old and 40% of children 7-12 years old. 3.5 million children are working, and 20,000 are child prostitutes. 85,000 street children live in 17 cities. Maternal mortality is estimated at 1600 women each year, and 24% of deaths in 78 hospitals were due to induced abortion. About 2.7 million women have unmet need for family planning, and 1.8 million desire family planning but are not using any method.

  20. Estudio del CH interestelar

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.
