Epidemiología y Control de la Enfermedad de Chagas en el Departamento de Cochabamba (Bolivia).
2015
La enfermedad de Chagas es uno de los problemas más graves de salud pública que afectan a América Latina; históricamente extensas áreas de Bolivia han registrado la mayor prevalencia de la infección por su agente causal, el protozoo Trypanosoma cruzi. A principios del año 2000, en este país se puso en marcha un programa de control vectorial, que consistió en el rociado masivo de viviendas con insecticidas piretroides, instaurado para controlar la infestación de viviendas por los insectos hematófagos que transmiten la enfermedad. En este trabajo se proporciona una evaluación detallada de los efectos de este programa en el Departamento de Cochabamba, uno de los lugares más endémico de todo el…
Synthesis and Structures of Aluminum and Magnesium Complexes of Tetraimidophosphates and Trisamidothiophosphates: EPR and DFT Investigations of the P…
2005
Reactions of (RNH)3PNSiMe3 (3a, R = tBu; 3b, R = Cy) with trimethylaluminum result in the formation of {Me2Al(μ-NtBu)(μ-NSiMe3)P(NHtBu)2]} (4) and the dimeric trisimidometaphosphate {Me2Al[(μ-NCy)(μ-NSiMe3)P(μ-NCy)2P(μ-NCy)(μ-NSiMe3)]AlMe2} (5a), respectively. The reaction of SP(NHtBu)3 (2a) with 1 or 2 equiv of AlMe3 yields {Me2Al[(μ-S)(μ-NtBu)P(NHtBu)2]} (7) and {Me2Al[(μ-S)(μ-NtBu)P(μ-NHtBu)(μ-NtBu)]AlMe2} (8), respectively. Metalation of 4 with nBuLi produces the heterobimetallic species {Me2Al[(μ-NtBu)(μ-NSiMe3)P(μ-NHtBu)(μ-NtBu)]Li(THF)2} (9a) and {[Me2Al][Li]2[P(NtBu)3(NSiMe3)]} (10) sequentially; in THF solutions, solvation of 10 yields an ion pair containing a spirocyclic tetraimid…

Studies on the determinants of migration and the spatial concentration of labour
2003
This thesis consists of five empirical studies which seek to understand the processes behind interregional migration decisions and the spatial concentration of labour. The empirical studies are preceded by an introductory chapter that, among other topics, discusses spatial concentration in Finland between 1980 and 2000, and surveys prior evidence on the determinants of migration. The thesis mainly utilises Finnish longitudinal population census data from 1993?1996. A variety of advanced microeconometric methods are used in the modelling of the migration phenomenon to ensure robustness and the reliability of the results. The results of the thesis imply that person-specific productivity has h…
Porolaidunnuksen vaikutus sammalten monimuotoisuuteen tuottavilla ja vähätuottoisilla tuntureilla pohjoisessa Fennoskandiassa
2010
Laiduntajat vaikuttavat kasvillisuuteen useilla sekä suorilla että epäsuorilla mekanismeilla, joista epäsuorat voivat olla ekosysteemiprosessien kannalta tärkeämpiä. Vähätuottoisella tundralla kasvinsyöjien vaikutuksen kasvillisuuteen tiedetään olevan merkittävä, mutta suuri osa tutkimuksesta on keskittynyt laiduntajien ravintokasveihin. Tundralla sammalet muodostavat suuren osan kasviyhteisöjen biomassasta ja monimuotoisuudesta, ja niiden on havaittu toimivan laiduntajien vaikutusten välittäjinä muuhun kasvillisuuteen ja maaperään. Laidunnuksen vaikutuksia sammalyhteisöihin on kuitenkin tutkittu hyvin vähän. Tässä tutkimuksessa selvitettiin poron (Rangifer tarandus tarandus L.) laidunnukse…
Teacher emotional support in relation to social competence in preschool classrooms
2020
The present study aimed to investigate the associations between teachers’ observed emotional support and social competence among Finnish pre-schoolers (6-year-olds). The quality of emotional support was observed using the Classroom Assessment Scoring System Pre-K in 47 preschool classrooms twice across the preschool year. Teachers rated children’s social competence in autumn and again in spring, using the Multisource Assessment of Social Competence Scale (MASCS), which produced sum scores for cooperating skills, empathy, impulsivity, and disruptiveness. Consistent with the transactional model, we specified reciprocal (auto-regressive and cross-lagged) relationships within a Multilevel Struc…
Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation
2021
The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …

La nuova soglia di punibilità nell'omesso versamento delle ritenute previdenziali e assistenziali fra dimensione dogmatica e capacità "selettiva"
2019
This study concerns the new financial threshold of punishability introduced by legislative decree n. 8/2016 for the criminal offence of failing to pay pension and welfare deductions (art. 2 legis. Decree n. 463/ 1983). After a critical examination of the first interventions of the Supreme Court on its theoretical framework, the essay analyses the significant relationships between the harmfulness of the offence and the threshold itself, to individuate its legal nature. In the first place, we highlight how the protected interest cannot be read in financial terms, as the protection of functional interests emerges, to be anchored, amongst others, to the constitutional principles about pensions …
Dom på overføring til tvungent psykisk helsevern : en kvalitativ studie om erfaringer og utfordringer ansatte innen psykisk helse opplever i forhold …
2016
Masteroppgave psykisk helsearbeid - Universitetet i Agder 2016 Background: The subject of this study is «Sentencing to compulsory mental health care». The choice of subject is sprung from a desire to gain a better knowledge of the challenges related to providing a good service for patients sentenced to compulsory mental health care (TPH). At the same time the study is seeking a more comprehensive understanding of the already known challenges concerning the collaboration between the first and second line services providing for this group of patients. The study's findings are discussed in light of a dialogical perspective of interaction. Selection and method: Qualitative study using participa…
