On overall sampling plan for small area estimation
2017
The time and budget restrictions in survey sampling can impose limits on the area sample sizes. This may reduce the possibility to obtain area-specific and population parameters estimates with adequate precision. Market research companies and institutes for producing official statistics face frequently this problem. Various models and methods for small area estimation (SAE) have been developed to solve this problem. The sample allocation must support the selected model and method to ensure efficient estimation and must be implemented in the design phase of the survey. The proposed allocation is developed by incorporating auxiliary information, a model, and an estimation method. The estimate…
Dead wood profile of a semi-natural boreal forest – implications for sampling
2019
Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead wood, and on the effect of sampling intensity on the dead wood estimates. In a semi-natural boreal forest, we measured every dead wood item over 2 cm in diameter from 80 study plots. From eight plots, we further recorded dead wood items below 2 cm in diameter. Based on these data we constructed the full dead wood profile, i.e. the overall number of dead wood items and their distribution among different tree species, volumes of different size and decay stage categories. We …
Māsu komunikācijas prasmes un to efektivitātes vērtējums neatliekamās medicīnas nodaļā
2015
Bakalaura darba tēma – Māsu komunikācijas prasmes un to efektivitātes vērtējums neatliekamās medicīnas nodaļā. Tēmas aktualitāti nosaka randomizēti pētīju saistībā ar māsu komunikācijas prasmju apmācību un to efektivitātes pierādījumu turpmākā medicīnas aprūpes sniegšanā un iznākumu novērtēšanā. Māsu komunikācijas prasmes apmācība pierādīja, ka māsu prasmes komunicēt bija efektīvākas psihosociālā atbalsta sniegšanā, palielināja prasmes konfliktu risināšanā. Darba mērķis ir noskaidrot māsu komunikācijas prasmes efektivitāti neatliekamās medicīnas nodaļās. Pētniecības uzdevumi ir izstrādāt pētījuma instrumentu – anketu, veikt respondentu aptauju, kvantitatīvi veikt datu analīzi par pētījuma i…
Satisfação Profissional no Docente Dominicano: Antecedentes Profissionais
2019
Resumen La satisfacción laboral del colectivo docente ha sido estudiada desde diversas perspectivas, debido a los importantes efectos que esta puede tener tanto a nivel económico como a nivel organizacional. La muestra empleada en este trabajo se compone de 978 docentes dominicanos, y fue obtenida mediante un muestreo estratificado, y, por tanto, representativo de la población. En este estudio se examina un modelo de ecuaciones estructurales en el cual el contexto de trabajo y las condiciones laborales afectan el burnout y el engagement de los profesores. A su vez, se plantea que burnout y engagement afectan la satisfacción laboral docente. El modelo ajustó a los datos: x2(223)= 1089.9, p<.…
Improved High-Fidelity IPMSM mathematical model Including Saturation, Cross-Coupling, Torque Ripple and Iron Loss effects
2022
For enhanced control algorithm design purposes, accurate and high-fidelity electrical machine mathematical models are fundamentals. Usually, accurate evaluation of electrical machine behaviour requires finite element analysis (FEA) with consequent high-computational times. This paper presents an improved high-fidelity Interior Permanent Magnet Synchronous Machine (IPMSM) mathematical model including saturation, cross-coupling, torque ripple and iron loss effects. This model has been implemented in Matlab®/Simulink environment and its parameters are implemented by the use of lookup tables. To validate the modelling approach proposed, a comparative analysis between the proposed Matlab®/Simuli…
Understanding teachers’ mental models of collaboration to enhance the learning community
2022
This study examined representations of Finnish basic education teachers’ mental models of collaboration to reveal the background features that enable or hinder changes in a school community and teacher collaboration. In this case study, we explored 41 teachers’ mental models of collaboration in a one-school community to identify and understand the features that enhance or challenge collaboration. The findings raise the question of how collaboration can support a school’s transition to a unified comprehensive school, when teachers are accustomed to working alone with a strong sense of autonomy and diverse mental models of collaboration. The findings revealed that collaboration is mainly limi…
Sconfinamenti. La strana storia della letteratura in Roma antica
2018
Oggetto di questo contributo è l'analisi di come, nella letteratura latina, lo “sconfinamento” rappresenti un principio vitale e virale di rinnovamento, che funziona sul piano delle forme letterarie ma anche delle idee, dei significati, delle proposte etiche e politiche che queste vogliono mettere in circolo.
Could a Behavioral Model Explain Adherence to Second-Level Colonoscopy for Colon Cancer Screening? Results of a Cross-Sectional Study of the Palermo …
2022
According to Italian Essential Levels of Assistance (ELA), a colonoscopy is strongly recommended after a positive fecal occult blood test (FOBT) due to its effectiveness in early colorectal cancer detection. Despite the evidence, the Palermo province population (Italy), after a positive FOBT, have a lower colonoscopy adherence compared to Italian standards. This cross-sectional study analyzed patients’ perceptions of colonoscopy procedures to understand the reasons for non-adherence. Patients with a positive FOBT who did not undergo a colonoscopy within the national organized screening program were administered a telephone interview based on the Health Belief Model (HBM) questionnaire. The …
Minori immigrati, scuola e modelli di integrazione
2013
Negli ultimi decenni si è consolidata in Italia una presenza elevata di minori provenienti da altri Paesi. Tale processo di evoluzione interna al Paese ha coinvolto sia il sistema di protezione sociale che quello educativo-scolastico. All'interno del nostro sistema sociale, la scuola è sempre più considerata non solo come luogo privilegiato dalle istituzioni per l'inserimento degli alunni stranieri, ma soprattutto come canale di dialogo tra la famiglia migrante e la comunità di accoglienza, confermandosi come ambito di intervento primario di educazione alla cittadinanza, rispetto alle altre agenzie educative, luogo nel quale le attività si collocano come un continuum che si muove tra appren…
