CNDOL: A fast and reliable method for the calculation of electronic properties of very large systems. Applications to retinal binding pocket in rhodopsin and gas phase porphine.

Very large molecular systems can be calculated with the so called CNDOL approximate Hamiltonians that have been developed by avoiding oversimplifications and only using a priori parameters and formulas from the simpler NDO methods. A new diagonal monoelectronic term named CNDOL/21 shows great consistency and easier SCF convergence when used together with an appropriate function for charge repulsion energies that is derived from traditional formulas. It is possible to obtain a priori molecular orbitals and electron excitation properties after the configuration interaction of single excited determinants with reliability, maintaining interpretative possibilities even being a simplified Hamiltonian. Tests with some unequivocal gas phase maxima of simple molecules (benzene, furfural, acetaldehyde, hexyl alcohol, methyl amine, 2,5 dimethyl 2,4 hexadiene, and ethyl sulfide) ratify the general quality of this approach in comparison with other methods. The calculation of large systems as porphine in gas phase and a model of the complete retinal binding pocket in rhodopsin with 622 basis functions on 280 atoms at the quantum mechanical level show reliability leading to a resulting first allowed transition in 483 nm, very similar to the known experimental value of 500 nm of "dark state." In this very important case, our model gives a central role in this excitation to a charge transfer from the neighboring Glu(-) counterion to the retinaldehyde polyene chain. Tests with gas phase maxima of some important molecules corroborate the reliability of CNDOL/2 Hamiltonians.

Las últimas importaciones romanas de cerámica en el este de Hispania Tarraconensis: una aproximación

En los últimos años, se han publicado diversos estudios que han permitido tener un buen conocimiento sobre las importaciones (terra sigillata, ánforas, lucern as) en la costa de la antigua Hispania Tarraconensis en época romana tardía. Este conocimiento, concerniente a los contextos urbanos (las ciudades antiguas de Barcino, Tarraco y otras) y los establecimientos rurales, permite determinar las tendencias de las importaciones y la economía en esta área entre los siglos IV y finales del VI e inicios del VII d.C. El aumento de datos necesita una interpretación, orientada hacia la determinación de las tendencias del comercio y las importaciones, y la relación económica entre la ciudad y el campo en la actual Cataluña en la Antigüedad Tardía. Con esta contribución, esperamos poder colaborar en la elaboración de un trabajo interpretativo de síntesis sobre estos aspectos.

Energiayhtiöiden ympäristöraportointi – Erilaiset yritykset raportoijina

Yleinen kiinnostus ympäristöasioita kohtaan on nousemassa, ja yritysten sidosryhmät kaipaavat enemmän tietoa yritysten toimista ympäristövaikutusten vähentämiseksi. Erityisesti tiedon tarve on kasvanut aloilla, joilla yritystoiminnalla on paljon ympäristövaikutuksia. Yhä useammat yritykset raportoivatkin ympäristövastuusta yhteiskuntavastuun osana. Raportointi on kuitenkin laadultaan ja kattavuudeltaan vaihtelevaa ja yleisesti riittämätöntä ja puolueellista. Tämä pro gradu- tutkielman tarkoituksena on kuvata mahdollisimman kattavasti kuuden Suomessa toimivan energiayhtiön ympäristöraportointia. Tutkimuksessa pyritään myös löytämään eroja ja yhtäläisyyksiä raportointiin liittyen, ja tutkimaan niihin vaikuttavia tekijöitä. Tutkimusmenetelminä käytetään sekä laadullista, että määrällistä analyysiä. Tutkimusaineisto koostuu vuosien 2006–2008 ympäristöraportoinnista. Tutkielman johtopäätöksinä esitetään, että raportointi ympäristöasioista on varsin eri tasolla erilaisissa energiayhtiöissä. Tutkimustulokset tukevat aiempaa tutkimusta aiheesta: ympäristöraportoinnin laatua ja kattavuutta selittäviä tekijöitä ovat yrityksen koko ja toimialue, yhtiömuoto sekä sidosryhmäsuhteet. Pienten, paikallisten ja erityisesti osuuskuntamuotoisten yritysten ympäristöraportointia kannattaisi kehittää, sillä niillä olisi paljon hyvää kerrottavaa. Korkeatasoinen yhteiskuntavastuuraportointi antaa yritykselle kilpailuedun lisäksi myös muita sisäisiä ja ulkoisia hyötyjä.

Llegint Cinema. Anàlisi de la representació de la malaltia mental en el setè art

El present treball és un estudi sobre l'estigma social en la malaltia mental i la representació d'aquest al cinema. Aquesta anàlisi s'ha portat a terme a partir de dues línies de treball. Per una banda amb l'anàlisi interpretativa de dotze pel·lícules utilitzant els indicadors de 'perillositat'; 'incapacitat per a la vida'; 'incurabilitat'; 'pèrdua de rols socials'; 'por al rebuig i/o por a les relacions socials'; i per l'altra banda a partir d'un grup de discussió, en el qual s'han visionat fragments de cinc pel·lícules amb set estudiants del Grau d'Educació Social de la Universitat de Vic. Dels resultats obtinguts es desprèn que la pel·lícula és un mitjà de comunicació mitjançant el qual els estereotips són usats en favor de l'espectacle, estigmatitzant així les persones diagnosticades de malaltia mental. Aquest és un dels motius que fan valorar el cinema com un recurs educatiu a considerar tant en la formació d'educadors i educadores socials com en els projectes d'intervenció socioeducativa.

Challenges to patient-centred care in a general internal medicine context: findings from an exploratory study

Introduction. If we are to promote more patient-centred approaches in care delivery, we have to better characterize the situations in which being patient-centred is difficult to achieve. Data from professionals in health and social care are important because they are the people charged with operationalizing patient-centred care (PCC) in their daily practice. However, empirical accounts from frontline care providers are still lacking, and it is important to gather experiences not only from doctors but also from the other care providers. Indeed, experiences from different professions can help inform our understanding of patient care, which is expected to be both patient-centred and collaborative. Methods. This study was based on the following research question: What factors make the provision of PCC difficult to achieve? Sample and setting. A purposeful sampling technique was used, allowing for a series of choices about the participants and their professional affiliation. Because patient-centredness is the focus, 3 professions appeared to be of special interest: general internists, nurses and social workers. The study was undertaken in the General Internal Medicine Division of a teaching hospital located in a North American context. Data Collection. To answer the research question, a methodological approach based on a theory called phenomenology was chosen. Accordingly, semi-structured interviews were used since they generate understanding of the meanings different individuals have of their lived world. Interviews with 8 physicians, 10 nurses and 10 social workers were eventually conducted. Data analysis. An inductive thematic analysis was employed to make sense of the interview data. Results. The thematic analysis allowed identifying various types of challenges to PCC. Although most of the challenges were perceived by all three groups of professionals, they were perceived to a different degree across the professions, which likely reflected the scope of practice of each profession. The challenges and their distribution across the professions are illustrated in Table 1. Examples of challenges are provided in Table 2. Discussion. There is a tension between what is supposed to be done - what stands in the philosophy of patient -centredness - and what is currently done - the real life with all the challenges to PCC. According to some participants' accounts, PCC clearly risks becoming a mere illusion for health care professionals on which too great pressures are imposed.

La controverse avant le film : quelle politique pour Good Night, And Good Luck ?

This article aims to explain how newspapers commented on the movie Good Night, and Good Luck before its release. The media coverage anticipated George Clooney's film as a partisan attack launched against George W. Bush's policy since 9/11. Clooney advocates another reading: the historic confrontation between journalist Edward Murrow and Senator Joseph McCarty permits to reflect on the crucial role that the media play for democracy. Such reflection tries to prevent the dividing of the public sphere into antagonistic camps opposing "friends" to "foes," a division that undermines the possibility of a true pluralism. Our socio-semiotic analysis will focus on the critical work accomplished by the media, and on the way that work determines the collective meaning of a cultural object. Simultaneously, we will discuss the necessary conditions for pluralism in a public sphere.

Il viaggio di Faust in Italia : percorsi di ricezione di un mito moderno

La tesi descrive il fenomeno di ricezione del mito faustiano all'interno della tradizione letteraria italiana di Otto e Novecento (1808-1945) nel suo sviluppo diacronico, individuando i nodi processuali emergenti ritenuti sistematici accanto alle tipologie predominanti della risposta testuale e alle più proficue rifunzionalizzazioni letterarie. La storia del mito di Faust è stata considerata aristotelicamente nella sua natura complessa ed evolutiva di fabula rinarrata, e di volta in volta risemantizzata in nuovi sistemi di valori, estetici e ideologici. Ma soprattutto in nuovi sistemi testuali. Scopo primario è stato infatti quello di comprendere come il mito di Faust sia entrato dentro alla cultura letteraria italiana e come abbia agito al suo interno, interferendo con essa. Naturalmente lo scambio e gli sviluppi hanno investito in modo reciproco e la tradizione accogliente e il mito stesso, producendo un allargamento esegetico delle sue possibilità semantiche: è infatti emersa una storia testuale che tematizza nel tempo il medesimo mito lungo assi interpretative anche estremamente divergenti. La ricerca ha portato alla scoperta di una ricca testualità rimossa dal canone della storia della letteratura italiana, anche se spesso prevalgono i testi-documento sui testi esteticamente più validi e significativi in sé; si tratta di una testualità talmente quantitativamente ricca da invitare ad un ripensamento qualitativo del fenomeno generale. Il mito di Faust, per due secoli percepito dalla critica dominante come distante ed estraneo alla cultura letteraria italiana, è invece riuscito ad entrare nella tradizione letteraria italiana, anche se attraverso modalità molto controverse: in linea di massima è potuto passare dal canone statico al canone dinamico laddove ha saputo influenzare e stimolare nuove vie significative di sviluppo formale. Il confronto della cultura letteraria italiana con il mito di Faust è stato in effetti caratterizzato subito da un doppio movimento discratico di rifiuto e dialogo. Il principale fattore di rifiuto è stato di carattere culturale: la difficoltà ad accettare un equilibrio fatto non di antitesi risolte in una sintesi ma di polarità aperte, irrisolte, in perpetuo bilanciamento, anche a livello formale reso in una tragedia franta in scene apparentemente autonome, divisa in due parti così diverse e chiusa da un lieto fine, mal si confaceva ai diffusi canoni classicisti di equilibrio formale, nonché alle esigenze romantiche di poesia moralmente chiara nel suo messaggio. Da qui le diffuse accuse di scarsa chiarezza e ambiguità morale, che andavano direttamente ad incontrarsi e sommarsi con i pregiudizi più propriamente teologico- religiosi di estraneità a quel mito nato come saga luterana dichiaratamente anti-papale. La condanna di carattere moralistico-cattolico risulta nei fatti propria più di certa cultura che non del largo pubblico che invece nel corso dell'Ottocento dimostra di gradire le versioni per musica e balletto di argomento faustiano, per quanto semplificata ed edulcorate rispetto alla leggenda originaria così come rispetto alla tragedia goethiana. Rispetto a tutti questi elementi di resistenza e rifiuto l'opera Mefistofele di Boito si presenta come snodo di opposizione consapevole e riferimento duraturo d'interrogazione critica. La principale linea di avvicinamento invece tra la cultura letteraria italiana e il mito di Faust resta quella del parallelo, già ideato dagli stessi intellettuali tedeschi d'inizio Ottocento, con l'opera ritenuta massima nel nuovo canone nazionale italiano da fine Settecento ad oggi: la Divina Commedia. Tanta critica, almeno fino alla metà del XX secolo, si rifà più o meno esplicitamente a questo parallelo pregiudiziale e testualmente piuttosto infondato ma molto produttivo, come si è attestato, a livello creativo. Questa ricostruzione ha voluto nel suo complesso dimostrare sul campo il valore di questo macrotesto faustiano come una delle vie maestre della dialettica tra tradizione e modernità, ancor più significativa nell'ambito di una cultura letteraria come quella italiana che, dopo l'estinguersi della sua centralità in epoca rinascimentale, si è rivelata particolarmente resistente al dialogo con le altre letterature fino al pieno Novecento.

"Quería crear un nuevo cosmos" : Aleksandr Scriabin y su sonata para piano nº 9

A partir de l’estudi general de l’obra d’Aleksandr Scriabin i a partir de l’anàlisi particular de la Sonata núm. 9 així com de les distintes influències que va tenir, el treball pretén fer una valoració de com caldria interpretar la Sonata núm. 9. És per això que hom fa una introducció general a la vida de Scriabin i el situa en el seu context històric; estudia el seu interès per la filosofia i com aquesta va influir en la seva obra. Alhora hom analitza la faceta de Scriabin com a pianista i en revisa l’obra com a compositor. La segona part del treball, pròpiament analítica, entra en la qüestió de les sonates i la importància que adquireixen en tota la seva obra per tal de centrar-se, en el darrer punt, en la Sonata núm. 9 i l’enfocament interpretatiu que podria tenir. Aquí, a partir del que prèviament s’ha estudiat, hom proposa una possibilitat interpretativa. En relació a aquest punt es comparen interpretacions de diversos pianistes.

La radicalización Heideggeriana del método fenomenológico

Este trabajo quiere esclarecer cómo y por qué, en la doctrina del «primer» Heidegger,la hermenéutica emerge como el complemento metodológico indispensable para el transcendentalismo de la fenomenología. Constata que la afinidad metodológica es el vínculo decisivo entre esta doctrina y la ontología fundamental, en contraste con una manifiesta disparidad temática: la conciencia, la intencionalidad y la reflexión son tres cruciales referenciasfenomenológicas que carecen de contrapartida fundamental-ontológica. Pero si Heidegger preserva la dimensión transcendental recogida de la fenomenología, tambiénimprime a su doctrina un carácter específicamente hermenéutico, patente en la transformación que recibe la noción capital de Auslegung. Hermenéutica y transcendentalismo, en efecto,no sólo no son antagónicos sino que estjn armonizados en el rnodus operandi de la ontología fundamental. En su indagación del a priori de toda constitución de sentido, tributaria de un antideductivismo tan exacerbado como el de la fenomenología, Heidegger introduce una dimensión metodológica inédita. Al fin y al cabo, la automostración del ser no ocupa el lugar teórico, supuestamente ametódico, que la fenomenología asigna a la in-mediatez.Entender esta mutación del método fenomenológico, desde luego, conlleva explorar en detalle cómo integró Heidegger las dispares componentes doctrinales de la ontología fundamental y por qué se empeñó en cuestionar el carácter neutral que se suele exigir al método.Transponiendo el transcendentalismo presencialista de Husserl en un proyecto ontológico, reinterpretó la metodología de la «intuitividad presentificadora» hasta hacerla compatible con una noción radicalmente ampliada de fenómeno. Así una indagación fenomenológica legítima ha de investigar transcendentalmente el «sentido del ser» como el apriori absoluto.La fenomenología ha de ser realizada como ontología.

El significat de les activitats aquàtiques del nadó des d'una perspectiva evolutiva

Aquest article pretén d’aprofundir des d’una perspectiva evolutiva en l’estudi i l’anàlisi de les activitats aquàtiques del nadó. A partir d’aquí, l’article interpreta des de l’òptica filogenètica i ontogenètica de les activitats aquàtiques dels nadons, quin significat tindran aquestes activitats en el seu desenvolupament general. Per assolir els objectius fixats, l’article utilitza un enfocament fenomenològic (Husserl, 1996) que se sustentarà conceptualment en l’abordatge filogenètic del desenvolupament psicomotriu de Fonseca (1998). Partint d’aquesta estructura, s’estudiaran les raons filogenètiques i ontogenètiques que ens poden significar les activitats aquàtiques del nadó per tal que, en última instància, i des de la línia més existencial de la fenomenologia (Sartre, 1999; Merleau-Ponty, 2000), puguem argumentar la significació evolutiva d’aquestes activitats.

Saako historiasta selvää? Monikulttuuriset yläkoululaiset historian lähteillä historian taidot motiivien, seurauksien, historian tulkintojen ja lähteiden luotettavuuden arvioinneissa

The research assesses the skills of upper comprehensive school pupils in history. The focus is on locating personal motives, assessing wider reasons hidden in historical sources and evaluating source reliability. The research also questions how a wide use of multiple sources affects pupils’ holistic understanding of historical phenomena. The participants were a multicultural group of pupils. The origins of their cultures can be traced to the Balkan, the Middle East, Asia and Europe. The number of native Finnish speakers and pupils speaking Finnish as their second language was almost equal. The multicultural composition provides opportunities to assess how culturally responsive learning history from sources is. The intercultural approach to learning in a multicultural setting emphasizes equality as a precondition for learning. In order to set assignments at least to some extent match with all participants only those answers were taken into account which were produced by pupils who had studied history for a similar period of time in the Finnish comprehensive school system. Due to the small number of participants (41), the study avoids wide generalizations. Nevertheless, possible cultural blueprints in pupils’ way of thinking are noted. The first test examined the skills of pupils to find motives for emigration. The results showed that for 7th graders finding reasons is not a problematic task. However, the number of reasons noticed and justifications varied. In addition, the way the pupils explained their choices was a distinguishing factor. Some pupils interpreted source material making use of previous knowledge on the issue, while other pupils based their analysis solely on the text handed and did not try to add their own knowledge. Answers were divided into three categories: historical, explanatory and stating. Historical answers combined smoothly previously learned historical knowledge to one’s own source analysis; explanatory answers often ignored a wider frame, although they were effective when explaining e.g. historical concepts. The stating answers only noticed motives from the sources and made no attempts to explain them historically. Was the first test culturally responsive? All pupils representing different cultures tackled the first source exam successfully, but there were some signs of how historical concepts are understood in a slightly different way if the pupil’s personal history has no linkage to the concepts under scrutiny. The second test focused on the history of Native Americans. The test first required pupils to recognize whether short source extracts (5) were written by Indians or Caucasians. Based on what they had already learned from North American history, the pupils did not find it hard to distinguish between the sources. The analysis of multiphase causes and consequences of the disputes between Native Americans and white Americans caused dispersion among pupils. Using two historical sources and combining historical knowledge from both of them simultaneously was cumbersome for many. The explanations of consequences can be divided into two groups: the ones emphasizing short term consequences and those placing emphasis on long term consequences. The short term approach was mainly followed by boys in every group. The girls mainly paid attention to long term consequences. The result suggests that historical knowledge in sources is at least to some extent read through role and gender lenses. The third test required pupils to explain in their own words how the three sources given differed in their account of living conditions in Nazi Germany, which turned out to be demanding for many pupils. The pupils’ stronghold was rather the assessment of source reliability and accounts why the sources approached the same events differently. All participants wrote critical and justified comments on reliability and aspects that might have affected the content of the sources. The pupils felt that the main reasons that affected source reliability were the authors’ ethnic background, nationality and profession. The assessment showed that pupils were well aware that position in a historical situation has an impact on historical accounts, but in certain cases the victim’s account was seen as a historical truth. The account of events by a historian was chosen most often as the most reliable source, but it was often justified leniently with an indication to professionalism rather than with clear ideas of how historians conduct accounts based on sources. In brief, the last source test demonstrates that pupils have a strong idea that the ethnicity or nationalism determines how people explained events of the past. It is also an implication that pupils understand how historical knowledge is interpretative. The results also imply that history can be analyzed from a neutral perspective. One’s own membership in an ethnical or religious group does not automatically mean that a person’s cultural identity excludes historical explanations if something in them contradicts with his or her identity. The second method of extracting knowledge of pupils’ historical thinking was an essay analysis. The analysis shows that an analytical account of complicated political issues, which often include a great number of complicated political concepts, leads more likely to an inconsistent structure in the written work of pupils. The material also demonstrates that pupils have a strong tendency to take a critical stance when assessing history. Historical empathy in particular is shown if history somehow has a linkage to young people, children or minorities. Some topics can also awake strong feelings, especially among pupils with emigrant background, if there is a linkage between one’s own personal history and that of the school; and occasionally a student’s historical experience or thoughts replaced school history. Using sources during history lessons at school seems to have many advantages. It enhances the reasoning skills of pupils and their skills to assess the nature of historical knowledge. Thus one of the main aims and a great benefit of source work is to encourage pupils to express their own ideas and opinions. To conclude, when assessing the skills of adolescents in history - their work with sources, comments on history, historical knowledge and finally their historical thinking - one should be cautious and avoid cut off score evaluations. One purpose of pursuing history with sources is to encourage pupils to think independently, which is a useful tool for further identity construction. The idea that pupils have the right to conduct their own interpretations of history can be partially understood as part of a wider learning process, justification to study history comes from extrinsic reasons. The intrinsic reason is history itself; in order to understand history one should have a basic understanding of history as a specific domain of knowledge. Using sources does not mean that knowing history is of secondary importance. Only a balance between knowing the contextual history, understanding basic key concepts and working with sources is a solid base to improve pupils’ historical understanding.

Estructuración natural de las relaciones entre sonidos de altura definida : aproximación fenomenológica a las relaciones tonales

La mayoría de tratados de armonía enfocan las relaciones armónicas como el resultado de unas combinaciones concretas y hasta cierto punto aleatorias de sonidos y solamente muy de vez en cuando encontramos justificaciones de por qué unos determinados procesos armónicos tienen un resultado vivencial específico; incluso en esos casos, las explicaciones se quedan habitualmente en nada. En este trabajo estudiaremos a fondo cuáles son los fundamentos esenciales sobre los que se basa la música, entendida como un encadenamiento de frecuencias que, si bien es solamente una parte del todo musical, constituye un elemento muy importante. Para ello, la fenomenología de la música –el estudio del efecto de los sonidos sobre la conciencia humana– nos proporcionará las herramientas necesarias.
