Unconventional Determinants of Greenhouse Gas Emissions: The Role of Trust

[cat] Les normes socials han estat incloses en la teoria de l’acció col.lectiva per a superar les dificultats per explicar perquè la gestió del béns comuns podria ser més efectiva quan s’autoregula per les mateixes comunitats. El paper rellevant de la confiança en els altres s’ha identificat en diversos contextos d’acció social a nivell local, però només recentment s’ha considerat la idea que també podria ser rellevant en el cas de béns comuns de caire global, seguint l’evidència bàsicament descriptiva recollida per Elinor Ostrom. Però fins ara no hi havia proves quantitatives disponibles d’aquesta idea. Utilitzant un conjunt de dades de 29 països europeus durant el període 1990-2007, donem evidència empírica a favor del paper del nivell de confiança en els altres en el context dels béns públics globals. Concloem que el nivell de confiança en els altres té un impacte reductor de les emissions de gasos d’efecte hivernacle; per exemple, l’extrapolació dels resultats implicaria una reducció d’emissions d’Espanya del 12,5% si el nivell mitjà de confiança en els altres dels espanyols fos tan elevat com els dels suecs.

L'informatique: un outil remarquable pour l'enseignement de la médecine interne générale [The informatics: a remarkable tool for teaching general internal medicine].

INTERMED training implies a three week course, integrated in the "primary care module" for medical students in the first master year at the school of medicine in Lausanne. INTERMED uses an innovative teaching method based on repetitive sequences of e-learning-based individual learning followed by collaborative learning activities in teams, named Team-based learning (TBL). The e-learning takes place in a web-based virtual learning environment using a series of interactive multimedia virtual patients. By using INTERMED students go through a complete medical encounter applying clinical reasoning and choosing the diagnostic and therapeutic approach. INTERMED offers an authentic experience in an engaging and safe environment where errors are allowed and without consequences.

Diseño de aplicativos de "autodiagnóstico sectoriales" como soporte del trabajo autónomo en el nuevo EEES

El objetivo de estos aplicativos, centrados cada uno de ellos en diferentes sectores de la economía, es facilitar la consecución de uno de los objetivos vinculados a la implantación del Espacio Europeo de Enseñanza Superior (EEES), donde se establece que el proceso formativo universitario debe basarse en desarrollar el estudio continuado y autónomo de los estudiantes (self-regulated/managed learning). Nuestro aplicativo informático es un instrumento mediante el cual el alumno, de forma autónoma, puede autoevaluar cuál es su nivel de conocimiento de los contenidos de las asignaturas de Estadística (grado de A.D.E. de la Universitat de Barcelona) a través del análisis de una empresa ubicada en un determinado sector económico. En este sentido, también puede entenderse como un material didáctico en la línea del llamado aprendizaje basado en problemas (problem-based learning). Con una estructura dinámica, basada en cuestiones de opción múltiple, e incorporada como módulo dentro de la plataforma Moodle (utilizada por la Universitat de Barcelona), permite una ejecución "on-line" de su contenido. Nuestra herramienta es un ejemplo más de cómo el uso de las nuevas tecnologías de la información y la comunicación (TIC), puede contribuir enormemente a la innovación de los procesos de enseñanza-aprendizaje en el contexto universitario1

Leaving the Dark ages with AMIGA

We present an Analytic Model of Intergalactic-medium and GAlaxy (AMIGA) evolution since the dark ages. AMIGA is in the spirit of the popular semi-analytic models of galaxy formation, although it does not use halo merger trees but interpolates halo properties in grids that are progressively built. This strategy is less memory-demanding and allows one to start modeling at sufficiently high redshifts and low halo masses to have trivial boundary conditions. The number of free parameters is minimized by making a causal connection between physical processes usually treated as independent of each other, which leads to more reliable predictions. However, the strongest points of AMIGA are the following: (1) the inclusion of molecular cooling and metal-poor, population III (Pop III) stars with the most dramatic feedback and (2) accurate follow up of the temperature and volume filling factor of neutral, singly ionized, and doubly ionized regions, taking into account the distinct halo mass functions in those environments. We find the following general results. Massive Pop III stars determine the intergalactic medium metallicity and temperature, and the growth of spheroids and disks is self-regulated by that of massive black holes (MBHs) developed from the remnants of those stars. However, the properties of normal galaxies and active galactic nuclei appear to be quite insensitive to Pop III star properties due to the much higher yield of ordinary stars compared to Pop III stars and the dramatic growth of MBHs when normal galaxies begin to develop, which cause the memory loss of the initial conditions.

Studieaktivering : en ur empirin genererad modell för hur lärare skapar förutsättningar för lärande för elever i skolsvårigheter i årskurserna 7–9

Syftet med denna Pro gradu avhandling var att generera en modell för hur lärare skapar förutsättningar för lärande för elever i skolsvårigheter i årskurserna 7–9. Fokus låg på vad som uppfattas vara kärnproblematiken i dessa årskurser. Undersökningen var inriktad på lärare verksamma i lärartät undervisning, i vilken det finns färre elever per lärare eller fler lärare i gruppen än vanligt. Glasers riktlinjer för metoden för grundad teori användes som grund för studiens teorigenerering. Med hjälp av metoden kunde en modell skapas för lärarens arbete, med kärnproblematiken i åtanke. Modellen är baserad på de fenomen som hittats i empirin och inte på till exempel tidigare forskning. Tidigare forskning har använts som spegel för att lyfta fram väsentliga aspekter i modellen. Datainsamlingsmetod var i första hand intervju, men en elektronisk enkät fungerade också som data i teorigenereringen. Data bestod av 13 speciallärares enkätsvar och fem intervjuer med tre speciallärare och två ämneslärare i årskurserna 7–9. Kärnproblematiken, eller den så kallade kärnkategorin, i den genererade modellen är studieaktivering. Karaktäristika för arbete med att skapa förutsättningar för studieaktivering är reaktivitet, interaktion och ledarskap samt att trygghet skapas och att eleven får hjälp med att utveckla studiestrategier. Ett annat karaktäristikum är hur elevpåverkan möjliggörs. Elevens aktivitet i studierna kan påverkas på olika delnivåer. Förutsättningar för studieaktivering kan skapas genom att påverka elevens kompetenstankar, en självstyrd drivkraft i eleven, lärarens anpassade undervisningsstrategier, ett internt samspel i gruppen och ett externt samarbete runt eleven. Modellen som genererats i studien kan användas i det praktiska lärararbetet som en referensram för ett studieaktiverande arbete. Studieaktivering av elever i årskurserna 7–9 skulle vara viktigt med tanke på framtida studier och socialiseringen i samhället.

FUTURES OF FINNISH FOOD SYSTEM BY 2050. The perspective of resilience

Modern food systems face complex global challenges such as climate change, resource scarcities, population growth, concentration and globalization. It is not possible to forecast how all these challenges will affect food systems, but futures research methods provide possibilities to enable better understanding of possible futures and that way increases futures awareness. In this thesis, the two-round online Delphi method was utilized to research experts’ opinions about the present and the future resilience of the Finnish food system up to 2050. The first round questionnaire was constructed based on the resilience indicators developed for agroecosystems. Sub-systems in the study were primary production (main focus), food industry, retail and consumption. Based on the results from the first round, the future images were constructed for primary production and food industry sub-sections. The second round asked experts’ opinion about the future images’ probability and desirability. In addition, panarchy scenarios were constructed by using the adaptive cycle and panarchy frameworks. Furthermore, a new approach to general resilience indicators was developed combining “categories” of the social ecological systems (structure, behaviors and governance) and general resilience parameters (tightness of feedbacks, modularity, diversity, the amount of change a system can withstand, capacity of learning and self- organizing behavior). The results indicate that there are strengths in the Finnish food system for building resilience. According to experts organic farms and larger farms are perceived as socially self-organized, which can promote innovations and new experimentations for adaptation to changing circumstances. In addition, organic farms are currently seen as the most ecologically self-regulated farms. There are also weaknesses in the Finnish food system restricting resilience building. It is important to reach optimal redundancy, in which efficiency and resilience are in balance. In the whole food system, retail sector will probably face the most dramatic changes in the future, especially, when panarchy scenarios and the future images are reflected. The profitability of farms is and will be a critical cornerstone of the overall resilience in primary production. All in all, the food system experts have very positive views concerning the resilience development of the Finnish food system in the future. Sometimes small and local is beautiful, sometimes large and international is more resilient. However, when probabilities and desirability of the future images were questioned, there were significant deviations. It appears that experts do not always believe desirable futures to materialize.

The 2008 financial crisis and neoclassical economics

The 2008 global financial crisis was the consequence of the process of financialization, or the creation of massive fictitious financial wealth, that began in the 1980s, and of the hegemony of a reactionary ideology, namely, neoliberalism, based on self-regulated and efficient markets. Although capitalism is intrinsically unstable, the lessons from the stock-market crash of 1929 and the Great Depression of the 1930s were transformed into theories and institutions or regulations that led to the "30 glorious years of capitalism" (1948-1977) and that could have avoided a financial crisis as profound as the present one. It did not because a coalition of rentiers and "financists" achieved hegemony and, while deregulating the existing financial operations, refused to regulate the financial innovations that made these markets even more risky. Neoclassical economics played the role of a meta-ideology as it legitimized, mathematically and "scientifically", neoliberal ideology and deregulation. From this crisis a new capitalism will emerge, though its character is difficult to predict. It will not be financialized but the tendencies present in the 30 glorious years toward global and knowledge-based capitalism, where professionals will have more say than rentier capitalists, as well as the tendency to improve democracy by making it more social and participative, will b e resumed.

An examination of the effects on learning seen in children afforded the opportunity to control the order of repetitions for three novel spatiotemporal sequences

Children were afforded the opportunity to control the order of repetitions for three novel spatiotemporal sequences. The following was predicted: a) children and adults in the self-regulated (SELF) groups would produce faster movement (MT) and reaction times (R T) and greater recall success (RS) during retention compared to the age-matched yoked (YOKE) groups; b) children would choose to switch sequences less often than adults; c) adults would produce faster MT and RT and greater RS than the children during acquisition and retention, independent of experimental group. During acquisition, no effects were seen for RS, however for MT and RT there was a main effect for age as well as block. During retention a main effect for practice condition was seen for RS and failed to reach statistical significance for MT and RT, thus partially supporting our first and second hypotheses. The third hypothesis was not supported.

An Examination of the Development of Online Higher Education in Canada and China: Keeping Pace and Making Space

This study examined the similarities and differences that currently exist between Chinese and Canadian online higher education, and explored the economic, political, and sociocultural environments that have shaped online education in these two jurisdictions. Furthermore, this paper discussed the efficacy of, and potential for, future development of online learning in higher education in both Canada and China. The research employed a collective case study design to gather information and data on the development of online higher education. The analysis on Contact North in Canada and the One-Man University in China provide a comparative perspective on the development of 2 typical online higher educational institutions in these two countries. The study revealed that the development of online higher education is influenced by the economic, political, and sociocultural factors of environment. Contact North and the One-Man University share similarities in many aspects, but are characteristically different. The Contact North can set an example for establishing and operating a self-regulated MOOCs platform. The study also generated implications for both organizations.

Prédiction des habiletés et habitudes de conduite automobile sécuritaire chez les conducteurs âgés : apport de la neuropsychologie clinique

L’insécurité routière chez les conducteurs âgés est attribuable en partie, aux effets délétères du vieillissement normal sur le fonctionnement cognitif. Les méthodes d’évaluation neuropsychologique par les tests ayant montré une certaine efficacité dans le cas du dépistage des habiletés de conduite chez les conducteurs âgés atteints d’affections neurologiques pathologiques, la présente thèse vise à évaluer la pertinence de cette approche chez les conducteurs vieillissants de la population générale. Le principal objectif de cette thèse est ainsi d’obtenir une vue d’ensemble sur le rôle et la sensibilité des mesures neuropsychologiques dans la prédiction des habiletés et habitudes de conduite automobile sécuritaire chez les conducteurs âgés. Dans la même perspective, la thèse explore d’autre part le rôle de variables sociodémographiques et psychologiques. L’article 1 évalue la validité prédictive de sept tests des fonctions visuo-attentionnelles et de la mémoire de travail en regard des habiletés de détection périphérique chez 50 conducteurs âgés de 62 à 83 ans. L’étude sur simulateur de conduite comprend une condition de conduite simple et une condition plus soutenue incluant une distraction téléphonique de type « mains-libres ». Selon les résultats, certains tests cognitifs prédisent bien les temps de détection. En outre, la validité prédictive des tests est plus importante dans la situation de conduite plus exigeante. Cela dit, les résultats de l’article 2 révèlent que le recours aux stratégies d’évitement des situations exigeantes est plus prononcé chez les individus qui présentent des faiblesses à certains des tests neuropsychologiques proposés. Les résultats indiquent en outre que l’utilisation des stratégies d’évitement routier est plus fréquente chez les conducteurs ayant tendance à déprécier leurs habiletés de conduite générales, à exprimer une moindre perception de contrôle ainsi qu’une attitude défavorable à l’endroit des situations de conduite complexes ou risquées. Les stratégies d’évitement se révèlent donc comme des réponses autorégulatrices proportionnelles aux limitations cognitives et aux perceptions individuelles. Dans les deux études, l’âge ne permet pas d’expliquer les différences individuelles, ceci ni en termes d’habiletés de détection périphérique ni de tendances autorégulatrices. Le rôle du genre est cependant plus nuancé. Ainsi, le principal apport de la présente thèse réside dans la constatation que si d’une part, certaines limitations neuropsychologiques sont associées à une réduction des habiletés de détection périphérique, ces mêmes limitations s’accompagnent aussi de mesures autorégulatrices qui peuvent contribuer à réduire le risque routier. Il appert conséquemment que les méthodes de dépistage de l’insécurité routière chez les conducteurs âgés se basant sur l’évaluation des limitations cognitives et attentionnelles doivent également rechercher et évaluer la teneur de leurs comportements routiers autorégulateurs. Dans le contexte de vieillissement de la population, des interventions pourront également miser sur le renforcement de ces comportements.

Étude des liens entre l’orientation mentale paternelle et le développement des manifestations morales à l’âge préscolaire

Essai présenté à la Faculté des arts et des sciences en vue de l’obtention du doctorat en psychologie (D.Psy.)

Antike und moderne Strategien der Texterschließung

Lateinische Schriftsteller im Original zu lesen, fällt vielen Schülerinnen und Schülern in der Lektürephase des Lateinunterrichts schwer. In der vorliegenden Dissertation wird untersucht, inwiefern gezielter Einsatz von Lernstrategien das Textverständnis verbessern kann. Strategisches Arbeiten mit Texten kann bereits zu einem sehr frühen Zeitpunkt in schriftbasierten Kulturen nachgewiesen werden. In dieser Arbeit werden Quellentexte aus der griechisch-römischen Antike und dem Mittelalter hinsichtlich texterschließender Strategien untersucht, systematisiert, kommentiert und im modernen Lateinunterricht eingesetzt. Dabei arbeiten die Schülerinnen und Schüler selbstgesteuert und forschend-entdeckend mit Reproduktionen antiker Papyri und Pergamente. Im Laufe des Unterrichtsprojektes, das ich CLAVIS, lat. für „Schlüssel“, nenne, lernen die Schüler im Zusammenhang mit Fachinhalten des Lateinunterrichts sechs antike Strategien der Texterschließung kennen. Diese Strategien werden heute noch genauso verwendet wie vor 2000 Jahren. Unter Berücksichtigung der Erkenntnisse der modernen Lernstrategieforschung wurden die Strategien ausgewählt, die als besonders effektive Maßnahmen zur Förderung von Textverständnis beurteilt werden, nämlich CONIUGATIO: Vorwissen aktivieren, LEGERE: mehrfaches und möglichst lautes Lesen, ACCIPERE: Hilfen annehmen, VERTERE: Übersetzen mit System, INTERROGARE: Fragen zulassen, SUMMA: Zusammenfassung erstellen. Ziel von CLAVIS ist es, Schülern ein Werkzeug zur systematischen Texterschließung an die Hand zu geben, das leicht zu merken ist und flexibel auf Texte jeder Art und jeder Sprache angewendet werden kann. Um die Effektivität des Unterrichtsprojektes CLAVIS zu überprüfen, wurde mit zwei parallel geführten 10. Klassen am Johann-Schöner-Gymnasium in Karlstadt im Schuljahr 2009/10 eine Vortest-Nachtest-Studie durchgeführt. Eine der Klassen wurde als Experimentalgruppe mit Intervention in Form von CLAVIS unterrichtet, die andere Klasse, die die Kontrollgruppe bildete, erhielt kein strategisches Training. Ein Fragebogen lieferte Informationen zur Vorgehensweise der Schüler bei der Textbearbeitung in Vortest und Nachtest (jeweils eine Übersetzung eines lateinischen Textes in identischem Schwierigkeitsgrad). Die Auswertung der Daten zeigte deutlich, dass Textverständnis und Übersetzungsfähigkeit sich bei denjenigen Schülern verbesserten, die die CLAVIS-Strategien im Nachtest angewendet hatten. Im Zusammenhang mit der Neugestaltung der Lehrpläne auf dem Hintergrund der Kompetenzorientierung ergeben sich für das Fach Latein neue Chancen, nicht nur inhaltlich wertvolle Zeugnisse der Antike zur allgemeinen, zweckfreien Persönlichkeitsbildung von Schülerinnen und Schülern einzusetzen, sondern gezielt Strategien zu vermitteln, die im Hinblick auf die in einer Informationsgesellschaft unverzichtbare Sprach- und Textkompetenz einen konkreten Nutzen haben.

Prevalência da Automedicação nos alunos do Mestrado Integrado em Ciências Farmacêuticas da ULHT

A automedicação é uma prática cada vez mais comum em todo o mundo e quando praticada de forma responsável oferece diversos benefícios, nomeadamente uma maior autonomia das populações na gestão da sua saúde. No entanto, o consumo de medicamentos não deve ser banalizado e a orientação e aconselhamento por parte de um profissional de saúde como o farmacêutico será sempre uma mais-valia, na medida em que proporciona uma automedicação responsável, eficaz e segura. O presente trabalho teve como principais objectivos, determinar a prevalência da automedicação nos alunos do Mestrado Integrado em Ciências Farmacêuticas da Universidade Lusófona de Humanidades e Tecnologias e avaliar os factores associados a esta prática. Nesse sentido, foi desenvolvido um estudo descritivo transversal, com base num questionário aplicado a esta população. Os dados recolhidos foram posteriormente sujeitos a tratamento estatístico através do programa SPSS®. Considerando uma amostra de 138 indivíduos, os resultados mostraram que a prevalência da automedicação foi de 95,7%. Os principais sintomas que motivaram o recurso à automedicação foram os estados gripais e constipações (14,2%), as dores menstruais (11,1%), a tosse/rouquidão (10,2%), cefaleias (9,5%), febre (8.6%), rinorreia e congestão nasal (6,7%) e a rinite alérgica (5,1%). Os medicamentos mais usados, nos últimos dois anos, foram os anti-inflamatórios não esteróides (19,4%), os analgésicos e antipiréticos (19,2%), os descongestionantes nasais (12,8%), os antitússicos e expectorantes (11,8%), os anti-histamínicos (9,5%) e as vitaminas e sais minerais (7,9%). A grande maioria dos inquiridos (89,9%) mostrou-se consciente dos possíveis riscos inerentes à automedicação. Ainda assim, 29% afirmou já se ter automedicado, usando medicamentos sujeitos a receita médica.

Maturation of limbic corticostriatal activation and connectivity associated with developmental changes in temporal discounting

Temporal discounting (TD) matures with age, alongside other markers of increased impulse control, and coherent, self-regulated behaviour. Discounting paradigms quantify the ability to refrain from preference of immediate rewards, in favour of delayed, larger rewards. As such, they measure temporal foresight and the ability to delay gratification, functions that develop slowly into adulthood. We investigated the neural maturation that accompanies the previously observed age-related behavioural changes in discounting, from early adolescence into mid-adulthood. We used functional magnetic resonance imaging of a hypothetical discounting task with monetary rewards delayed in the week to year range. We show that age-related reductions in choice impulsivity were associated with changes in activation in ventromedial prefrontal cortex (vmPFC), anterior cingulate cortex (ACC), ventral striatum (VS), insula, inferior temporal gyrus, and posterior parietal cortex. Limbic frontostriatal activation changes were specifically associated with age-dependent reductions in impulsive choice, as part of a more extensive network of brain areas showing age-related changes in activation, including dorsolateral PFC, inferior parietal cortex, and subcortical areas. The maturational pattern of functional connectivity included strengthening in activation coupling between ventromedial and dorsolateral PFC, parietal and insular cortices during selection of delayed alternatives, and between vmPFC and VS during selection of immediate alternatives. We conclude that maturational mechanisms within limbic frontostriatal circuitry underlie the observed post-pubertal reductions in impulsive choice with increasing age, and that this effect is dependent on increased activation coherence within a network of areas associated with discounting behaviour and inter-temporal decision-making.
