Maanpuolustustahto asevelvollisen koulutuksen ja palveluksen onnistumista selittävänä tekijänä

Lähtökohta tälle tutkimukselle oli havainto siitä, että varusmiehillä maanpuolustustahto ja taisteluluottamus korreloivat. Tämä huomio oli mahdollista tehdä aikaisemmissa varusmiesaineistoilla tehdyissä tutkimuksissa, joissa olin ollut mukana. Tutkimuksen aineistoina olivat useat puolustusvoimissa kerätyt varusmiesten kyselytutkimusaineistot. Vertailuaineistoina käytin reserviläisille kertausharjoituksissa tehtyjen kyselyiden aineistoja. Olennaista oli selvittää, säilyikö havaittu riippuvuus kun muita mahdollisia tekijöitä otettiin huomioon. Tutkimus oli aikaisemmin kerättyjen aineistojen sekundaarianalyysi ja tutkijana en ollut voinut vaikuttaa kyselyjen sisältöön tai käytettyjen muuttujien ja mittareiden valintaan. Aineistot on kerätty kuvaileviin tarkoituksiin ja tästä syystä tämä tutkimus oli tilastollisesti kuvaileva. Keskeiset käytetyt aineistot olivat varusmiesten kotiuttamiskyselyiden eli loppukyselyiden aineistot kaikista varuskunnista vuosilta 2000 – 2008 sekä vuonna 2010 Siilasmaan työryhmää varten kerätty aineisto kolmesta varuskunnasta. Vuoden 2010 varusmiestutkimus oli toteutettu siten, että kysely tehtiin sekä palveluksen alussa että lopussa. Tässä aineistossa käytettiin monipuolisesti varusmiesten psykososiaalisen toimintakyvyn erilaisia mittareita. Maanpuolustustahto on käsitteellisesti laaja kokonaisuus, kuitenkin tässä tutkimuksessa se oli operationalisoitava käytettävissä olleiden osioiden avulla. Maanpuolustustahtoa tarkasteltiin sekä henkilökohtaisena että yleisenä maanpuolustustahtona sekä niiden yhdistelmänä, josta käytettiin myös nimitystä maanpuolustusajattelu. Käsitteellisesti suppeampi taisteluluottamus operationalisoitiin siten, että muuttujana se kuvasi varusmiehen luottamusta aseisiinsa, saamaansa koulutukseen sekä lähiryhmäänsä. Taisteluluottamuksen mittaamisen taustalla oli ajatus siitä, että tämän yksilökohtaisen mittarin keskiarvo on joukon koulutuksen onnistuneisuuden estimaatti. Taisteluluottamus oli tutkimuksessa varsinainen tulosmuuttuja. Tulosten perusteella yksittäisten varusmiesten psykososiaalisessa toimintakyvyssä on eroja. Erityisesti erottui yksittäisenä tekijänä sosiaalisuus, joka summamuuttujana oli muodostettu varusmiestutkimus 2010:n aineistossa Maanpuolustuskorkeakoulun Käyttäytymistieteen laitoksen laatimista osioista. Sosiaalisuus ennusti voimakkaasti varusmiehen etenemistä koulutuksessa aina johtajakoulutukseen saakka. Sosiaalisuuden kontrollointi tilastollisesti ei poistanut maanpuolustusajattelun ja taisteluluottamuksen välistä riippuvuutta. Varusmiestutkimus 2010 aineistossa oli mahdollista tarkastella maanpuolustusajattelun muutosta palvelusaikana ja muutoksen yhteyttä psykososiaalisen toimintakyvyn kuvaajiin. Stressaantumistaipumus ja neuroottisuus olivat yhteydessä maanpuolustustahdon laskuun. Tunteiden hallinnan kyky tuki varusmiehen maanpuolustustahdon ja taisteluluottamuksen kehittymistä. Tilastollinen kuvaus toteutettiin Mplus-ohjelmistolla lasketulla rakenneyhtälömallilla. Aineistoon sopiva malli oli mahdollista löytää. Mallin mukaan sosiaalinen pääoman yksilökohtaisena resurssina antaa mahdollisuuden kehittää ja säilyttää maanpuolustusajattelua, joka on yhteydessä itseluottamuksen luontoiseen taisteluluottamukseen varusmieskoulutuksen päättyessä. Koulutuksen aikana joukkoon kehittynyt kiinteys ja luottamus tukevat tätä kehitystä. Joukkotuotantomallilla saadaan aikaan joukkoja, joissa taisteluluottamus on yleensä tarvittavalla tasolla ja niitä voidaan käyttää osoitettuihin tehtäviin. Kertausharjoitukset ylläpitävät kiinteyttä, taisteluluottamusta ja sitä kautta joukon suorituskykyä. Tutkimuksessa havaittiin myös, että pysyvissä miehistön ryhmissä, joissa ryhmänjohtaja ja/tai jäseniä ei vaihtunut, koulutuksen tulokset olivat parempia kuin muuttuneissa ryhmissä. Edelleen havaittiin, että 12 kuukautta palvelleiden miehistön jäsenten joukossa palvelusmotivaatio laski enemmän kuin muissa varusmiesryhmissä. Yhdestätoista koulutuksen ja tutkimuksen asiantuntijasta koottu ryhmä arvioi tutkimuksen tuloksia sovelletulla Q-menetelmällä Facilitate Pro -ohjelmistoa käyttäen. Menettely tuotti lisänäkökohtia tulosten arviointiin sekä niiden soveltamiseen.

Étude comparée de la formation initiale des enseignants du primaire au Québec et en Finlande

Depuis les années 1980, la formation des enseignants a fait l’objet de réformes majeures dans la plupart des sociétés développées, souvent en étant directement articulée à un processus de «professionnalisation» (Tardif, Lessard & Gauthier, 1998). La professionnalisation de l’enseignement est aujourd’hui considérée comme un mouvement international (OCDE, 2005). Dans cette recherche de maîtrise, nous analysons la mise en œuvre de la professionnalisation et son articulation à l’organisation des programmes de formation des enseignants du primaire dans deux contextes : Finlande et Québec. L’intérêt d’une comparaison du Québec avec la Finlande découle des enquêtes PISA 2000, 2003, et 2006, qui ont permis de faire reconnaître le système éducatif finlandais comme l’exemple d’un système performant qui combine avec succès la qualité, l’équité et la cohésion sociale (Sahlberg, 2007). Or, parmi les nombreuses raisons présentées pour expliquer ce succès, une des plus importantes serait la formation des enseignants. En Finlande les enseignants réalisent une formation initiale de 5 ans. Mais au Québec les enseignants sont aussi hautement éduqués : ils réalisent une formation universitaire de 4 ans après deux années d’études pré-universitaires. Dans les deux contextes, les enseignants complètent 17 ans de scolarité. Quelles sont les similitudes et les différences entre les programmes de formation des enseignants du primaire en Finlande et au Québec? Comment et en quoi ce processus de professionnalisation, comme tendance internationale, a-t-il marqué les systèmes de formation d’enseignants finlandais et québécois ? Peut-on dégager, à partir de cette comparaison, des éléments d’un système de formation à l’enseignement de meilleure qualité pour le Québec?

Un cadre d’analyse interactionniste pour éclairer le rapport entre la formation et l’insertion professionnelle des candidats à l’enseignement au Québec

Ce mémoire est une recherche théorique qui tire son origine du constat selon lequel il est difficile d’analyser la réalisation du projet professionnel des candidats à l’enseignement. Tel est le cas en raison des particularités contextuelles et des pluralités théoriques relatives aux notions de formation et d’insertion. À partir de ce constat, ce mémoire propose un cadre d’analyse permettant de comprendre comment les jeunes enseignants du Québec appréhendent le « rapport entre » leur formation et leur insertion face aux différentes contraintes (i.e. rigidité du système institutionnel de la formation, marché de l’insertion fluctuant et saturé, etc.) et aux ressources disponibles (i.e. programme d’études, cours, etc.) pour réaliser leur projet professionnel. Il repose sur l’hypothèse selon laquelle, pour réaliser leur projet professionnel, les candidats à l’enseignement mobilisent des stratégies afin de négocier les contraintes et ressources de leurs contextes respectifs. Dans cette optique, la démarche de cette recherche théorique s’inscrit dans une perspective interactionniste, telle qu’elle est véhiculée par la tradition de Chicago (Chapoulie, 2001). Quelques postulats sont mobilisés pour baliser les différentes étapes d’élaboration du cadre d’analyse. Le premier postulat considère que le « point de vue » de l’acteur est prépondérant pour comprendre ses conduites (Morrissette, Guignon & Demaziére, 2011). Cela amène à articuler les ancrages théoriques nécessaires à l’élaboration du cadre d’analyse en croisant une sociologie interactionniste avec une sociologie de l’action. Plus particulièrement, les concepts de « définition de la situation » de Thomas (1923) et de la « représentation de soi » de Goffman (1969) sont mis à profit. Les notions de coopération, d’incertitude et de rationalité, tirées du modèle de l’acteur stratégique de Crozier et Friedberg (1981), viennent compléter les assises de la modélisation d’une trame de négociation (Strauss & Baszanger, 1992). Le deuxième postulat considère que les contextes, sont prépondérants pour expliquer les conduites humaines (Abbott, 1999). Ces contextes, dits «éloignés» et «rapprochés» de l’acteur, constituent le « contexte d’action » (Strauss & Baszanger, 1992). Ce faisant, ils influent sur les stratégies mobilisées par l’acteur candidat à l’enseignement. Le troisième postulat considère que le monde social est animé par des processus (re)créés au travers des interactions entre acteurs (Morrissette & Guignon, 2014). Il amène à envisager la formation et l’insertion comme des processus sujets à des redéfinitions continues. Cela conduit à repenser la réalisation du projet professionnel des candidats à l’enseignement sous l’angle du « rapport entre ». Ces trois postulats structurent le cadre d’analyse qui se présente comme une « trame de négociation ». Il est développé pour éventuellement éclairer les stratégies de négociation mobilisées en contexte par les candidats québécois à l’enseignement pour réaliser leur projet professionnel.

Construção de uma nova profissionalidade docente das equipas pedagógicas dos cursos de educação e formação através da sua transformação em comunidades de aprendizagem profissional

O sistema educativo e formativo português tem vindo a mudar significativamente, devido ao fenómeno da globalização e às exigências da sociedade do conhecimento. Com efeito, os desafios de uma economia mais dinâmica e competitiva, baseada no conhecimento requerem a definição de novas políticas educativas. Os objetivos de aumentar a equidade e a oportunidade de educação para todos os alunos e de combater o abandono e o insucesso escolar conduziram à implementação, em Portugal, de algumas medidas que envolvam os jovens em programas de formação, tais como os cursos de educação e formação (CEF). É no seio deste novo e complexo contexto educativo que colocamos a relevante questão: como podem as equipas pedagógicas dos cursos de educação e formação responder, adequadamente, às exigências de atuação neste tipo de percurso diversificado de formação? A natureza dos constantes constrangimentos que os professores enfrentam permitiu-nos concluir que estes têm de trabalhar sobre a sua própria capacidade de mudança, de forma a responderem a todas estas crescentes demandas, pelo que, neste sentido, a mudança assume-se como uma extraordinária oportunidade de desenvolvimento profissional. Esta construção de capacidade ou reculturing (Fullan, 2007) é o resultado de várias adaptações e decisões, tomadas pelos professores, colaborativamente como comunidades de aprendizagem profissional (CAP). Na verdade, nas CAP os docentes estão moral e intelectualmente comprometidos com a melhoria, a inovação e a sustentabilidade da educação, por conseguinte elas não são apenas um meio de melhorar os resultados dos alunos e de aumentar as suas aprendizagens, como são, também, o processo mais eficaz de implicar os docentes no desenvolvimento profissional contínuo, profundamente ligado à ação. Consequentemente, no sentido de transformar as equipas pedagógicas em comunidades de aprendizagem profissional apresentamos um projeto de formação que se concretizará através da implementação de um círculo de estudos, no contexto escolar, que pretende assegurar o desenvolvimento e a atualização dos conhecimentos e competências dos professores dos CEF e melhorar a qualidade e eficácia da aprendizagem e da prática docente. As expectativas em relação aos resultados desta formação são bastante elevadas e alicerçam-se na recetividade e disponibilidade demonstradas, por todos os professores dos CEF, para participarem neste projeto de formação.

Detection of faults in a high speed packaging machine using a multilayer perceptron (MLP)

In high speed manufacturing systems, continuous operation is desirable, with minimal disruption for repairs and service. An intelligent diagnostic monitoring system, designed to detect developing faults before catastrophic failure, or prior to undesirable reduction in output quality, is a good means of achieving this. Artificial neural networks have already been found to be of value in fault diagnosis of machinery. The aim here is to provide a system capable of detecting a number of faults, in order that maintenance can be scheduled in advance of sudden failure, and to reduce the necessity to replace parts at intervals based on mean time between failures. Instead, parts will need to be replaced only when necessary. Analysis of control information in the form of position error data from two servomotors is described.

Assisted remote viewing of a teleoperation work cell

Intelligent viewing systems are required if efficient and productive teleoperation is to be applied to dynamic manufacturing environments. These systems must automatically provide remote views to an operator which assist in the completion of the task. This assistance increases the productivity of the teleoperation task if the robot controller is responsive to the unpredictable dynamic evolution of the workcell. Behavioral controllers can be utilized to give reactive 'intelligence.' The inherent complex structure of current systems, however, places considerable time overheads on any redesign of the emergent behavior. In industry, where the remote environment and task frequently change, this continual redesign process becomes inefficient. We introduce a novel behavioral controller, based on an 'ego-behavior' architecture, to command an active camera (a camera mounted on a robot) within a remote workcell. Using this ego-behavioral architecture the responses from individual behaviors are rapidly combined to produce an 'intelligent' responsive viewing system. The architecture is single-layered, each behavior being autonomous with no explicit knowledge of the number, description or activity of other behaviors present (if any). This lack of imposed structure decreases the development time as it allows each behavior to be designed and tested independently before insertion into the architecture. The fusion mechanism for the behaviors provides the ability for each behavior to compete and/or co-operate with other behaviors for full or partial control of the viewing active camera. Each behavior continually reassesses this degree of competition or co-operation by measuring its own success in controlling the active camera against pre-defined constraints. The ego-behavioral architecture is demonstrated through simulation and experimentation.

Retificador entrelaçado com elevado fator de potência para operação de um veículo trólebus alimentado por redes em CA Ou CC

This paper presents the development and the main results for an interleaved boost rectifier operating as a special input power stage for a trolleybus type vehicle, allowing its feeding by alternate current (AC) or direct current (DC) distribution power systems. When feeding with two wires (single phase) alternate current distribution system, the converter accomplish active power factor correction, providing a relatively sinusoidal current with low total harmonic distortion (THD) and fully complying with IEC 61000-3-4 standards. In addition, a management control system promotes the required automatic operation changes for the proposed rectifier when the vehicle is changing from the DC distribution power system to the AC distribution power system and vice-versa, keeping its original electrical DC system characteristics for the adjustable speed driver sub-system. The main experimental results for a prototype rated at 150kW are presented, considering its application for a trolleybus with DC adjustable speed driver, demonstrating the proposed converter benefits and the possibility of AC feeding system for trolleybus type vehicle.

Light energy management in peach: utilization, photoprotection , photodamage and recovery. Maximizing light absorption in orchard is not always the best solution

The relation between the intercepted light and orchard productivity was considered linear, although this dependence seems to be more subordinate to planting system rather than light intensity. At whole plant level not always the increase of irradiance determines productivity improvement. One of the reasons can be the plant intrinsic un-efficiency in using energy. Generally in full light only the 5 – 10% of the total incoming energy is allocated to net photosynthesis. Therefore preserving or improving this efficiency becomes pivotal for scientist and fruit growers. Even tough a conspicuous energy amount is reflected or transmitted, plants can not avoid to absorb photons in excess. The chlorophyll over-excitation promotes the reactive species production increasing the photoinhibition risks. The dangerous consequences of photoinhibition forced plants to evolve a complex and multilevel machine able to dissipate the energy excess quenching heat (Non Photochemical Quenching), moving electrons (water-water cycle , cyclic transport around PSI, glutathione-ascorbate cycle and photorespiration) and scavenging the generated reactive species. The price plants must pay for this equipment is the use of CO2 and reducing power with a consequent decrease of the photosynthetic efficiency, both because some photons are not used for carboxylation and an effective CO2 and reducing power loss occurs. Net photosynthesis increases with light until the saturation point, additional PPFD doesn’t improve carboxylation but it rises the efficiency of the alternative pathways in energy dissipation but also ROS production and photoinhibition risks. The wide photo-protective apparatus, although is not able to cope with the excessive incoming energy, therefore photodamage occurs. Each event increasing the photon pressure and/or decreasing the efficiency of the described photo-protective mechanisms (i.e. thermal stress, water and nutritional deficiency) can emphasize the photoinhibition. Likely in nature a small amount of not damaged photosystems is found because of the effective, efficient and energy consuming recovery system. Since the damaged PSII is quickly repaired with energy expense, it would be interesting to investigate how much PSII recovery costs to plant productivity. This PhD. dissertation purposes to improve the knowledge about the several strategies accomplished for managing the incoming energy and the light excess implication on photo-damage in peach. The thesis is organized in three scientific units. In the first section a new rapid, non-intrusive, whole tissue and universal technique for functional PSII determination was implemented and validated on different kinds of plants as C3 and C4 species, woody and herbaceous plants, wild type and Chlorophyll b-less mutant and monocot and dicot plants. In the second unit, using a “singular” experimental orchard named “Asymmetric orchard”, the relation between light environment and photosynthetic performance, water use and photoinhibition was investigated in peach at whole plant level, furthermore the effect of photon pressure variation on energy management was considered on single leaf. In the third section the quenching analysis method suggested by Kornyeyev and Hendrickson (2007) was validate on peach. Afterwards it was applied in the field where the influence of moderate light and water reduction on peach photosynthetic performances, water requirements, energy management and photoinhibition was studied. Using solar energy as fuel for life plant is intrinsically suicidal since the high constant photodamage risk. This dissertation would try to highlight the complex relation existing between plant, in particular peach, and light analysing the principal strategies plants developed to manage the incoming light for deriving the maximal benefits as possible minimizing the risks. In the first instance the new method proposed for functional PSII determination based on P700 redox kinetics seems to be a valid, non intrusive, universal and field-applicable technique, even because it is able to measure in deep the whole leaf tissue rather than the first leaf layers as fluorescence. Fluorescence Fv/Fm parameter gives a good estimate of functional PSII but only when data obtained by ad-axial and ab-axial leaf surface are averaged. In addition to this method the energy quenching analysis proposed by Kornyeyev and Hendrickson (2007), combined with the photosynthesis model proposed by von Caemmerer (2000) is a forceful tool to analyse and study, even in the field, the relation between plant and environmental factors such as water, temperature but first of all light. “Asymmetric” training system is a good way to study light energy, photosynthetic performance and water use relations in the field. At whole plant level net carboxylation increases with PPFD reaching a saturating point. Light excess rather than improve photosynthesis may emphasize water and thermal stress leading to stomatal limitation. Furthermore too much light does not promote net carboxylation improvement but PSII damage, in fact in the most light exposed plants about 50-60% of the total PSII is inactivated. At single leaf level, net carboxylation increases till saturation point (1000 – 1200 μmolm-2s-1) and light excess is dissipated by non photochemical quenching and non net carboxylative transports. The latter follows a quite similar pattern of Pn/PPFD curve reaching the saturation point at almost the same photon flux density. At middle-low irradiance NPQ seems to be lumen pH limited because the incoming photon pressure is not enough to generate the optimum lumen pH for violaxanthin de-epoxidase (VDE) full activation. Peach leaves try to cope with the light excess increasing the non net carboxylative transports. While PPFD rises the xanthophyll cycle is more and more activated and the rate of non net carboxylative transports is reduced. Some of these alternative transports, such as the water-water cycle, the cyclic transport around the PSI and the glutathione-ascorbate cycle are able to generate additional H+ in lumen in order to support the VDE activation when light can be limiting. Moreover the alternative transports seems to be involved as an important dissipative way when high temperature and sub-optimal conductance emphasize the photoinhibition risks. In peach, a moderate water and light reduction does not determine net carboxylation decrease but, diminishing the incoming light and the environmental evapo-transpiration request, stomatal conductance decreases, improving water use efficiency. Therefore lowering light intensity till not limiting levels, water could be saved not compromising net photosynthesis. The quenching analysis is able to partition absorbed energy in the several utilization, photoprotection and photo-oxidation pathways. When recovery is permitted only few PSII remained un-repaired, although more net PSII damage is recorded in plants placed in full light. Even in this experiment, in over saturating light the main dissipation pathway is the non photochemical quenching; at middle-low irradiance it seems to be pH limited and other transports, such as photorespiration and alternative transports, are used to support photoprotection and to contribute for creating the optimal trans-thylakoidal ΔpH for violaxanthin de-epoxidase. These alternative pathways become the main quenching mechanisms at very low light environment. Another aspect pointed out by this study is the role of NPQ as dissipative pathway when conductance becomes severely limiting. The evidence that in nature a small amount of damaged PSII is seen indicates the presence of an effective and efficient recovery mechanism that masks the real photodamage occurring during the day. At single leaf level, when repair is not allowed leaves in full light are two fold more photoinhibited than the shaded ones. Therefore light in excess of the photosynthetic optima does not promote net carboxylation but increases water loss and PSII damage. The more is photoinhibition the more must be the photosystems to be repaired and consequently the energy and dry matter to allocate in this essential activity. Since above the saturation point net photosynthesis is constant while photoinhibition increases it would be interesting to investigate how photodamage costs in terms of tree productivity. An other aspect of pivotal importance to be further widened is the combined influence of light and other environmental parameters, like water status, temperature and nutrition on peach light, water and phtosyntate management.

Architectural development and dry matter production in a multisite trial on single and multiaxis apple trees (Malus domestica Borkh) grafted on different rootstocks

In two Italian sites, multiaxis trees slightly reduced primary axis length and secondary axis length of newly grafted trees, and increased the number of secondary shoots. The total length, node production, and total dry matter gain were proportional to the number of axis. Growth of both primary and secondary shoots, and dry matter accumulation, have been found to be also well related to rootstock vigour. A great variability in axillary shoot production was recorded among different environments. Grafted trees had higher primary growth, secondary axis growth, and dry matter gain than chip budded trees. Stem water potential measured in the second year after grafting was not affected by rootstocks or number of leaders. Measurements performed in New Zealand (Hawke’s Bay) during the second year after grafting revealed that both final length and growth rate of primary and secondary axis were related to the rootstock rather than to the training system. Dwarfing rootstocks reduced the number of long vegetative shoots and increased the proportion of less vigorous shoots.

Influence of plant structure, cultural pratices and environmental conditions on the development of the bacterial canker of kiwifruits

Italy has a preeminent rank in kiwifruit industry, being the first exporter and the second largest producer after China. However, in the last years kiwifruit yields and the total cultivated area considerably decreased, due to the pandemic spread of the bacterial canker caused by Pseudomonas syringae pv. actinidiae (Psa). Several climatic conditions and cultural practices affect the development of the bacterial canker. This research work focused on the impact of agricultural practices and microclimate conditions on the incidence and epidemiology of Psa in the orchard. Therefore, the effect of fertilization, irrigation, use of bio-regulators, rootstock, training system and pruning were examined. The effect of different tunnel systems was analyzed as well, to study the plant-pathogen interaction. Considering the importance of insects as vectors in other pathosystems, the role of Metcalfa pruinosa in the spread of the bacterial canker was investigated in controlled conditions. In addition, quality and storage properties of fruits from infected plants were assessed. The study of all these aspects of the agronomic practices is useful to define a strategy to limit the bacterial diffusion in the orchard. Overall, excess nitrogen fertilization, water stress, stagnant water supplies, pruning before summer and the high number of Metcalfa pruinosa increased the Psa incidence. In contrast, tunnel covers may be useful for the control of the disease, with special attention to the kind of material.
