Conceptions associated with sense of belonging in different school placements for Finnish pupils with special education needs

2015

AbstractThe aim of this study was to examine conceptions associated with sense of belonging (SEBE) in Finnish general and special school placements for pupils with special education needs. Five pupils were selected for this study by means of purposive sampling. They had a history of several school placements prior to arriving at their current special school. Qualitative phenomenographic analyses of interview transcripts revealed numerous conceptions regarding the pupils’ SEBE in the different educational placements. The pupils had undergone numerous placements in which their SEBE had been jeopardised, as disturbing relationships with teachers and peers seemed to have affected the pupils’ me…

Proposal of reference values of microbiological environment monitoring in foodservice establishments

2015

Introducción: Proponer una nueva referencia microbiológica ambiental en los servicios de restauración. Objetivo: El presente trabajo muestra la determinación y evaluación de la contaminación microbiológica generada en un establecimiento de servicio de alimentos. Método: Se basa en el muestreo microbiológico de superficie utilizando filtros de membrana de ésteres mixtos de celulosa y en el muestreo de aire utilizando placas de Petri. Resultados: Los límites de contaminación se establecieron antes y durante la elaboración de alimentos, mediante el análisis microbiológico de las superficies y del medio ambiente, sistemas de equipos, hasta límites confiables y estableciendo niveles de aceptació…

Wine and Its Legality-A Survey to Know the Consumer Opinions on the Activities of Sicilian Wine Companies Operating on Lands Confiscated from the Maf…

2014

The current guidelines of the European Union Common Agricultural Policy face the agricultural sector in the position of the backbone for the economic development of rural areas and regions with difficult economic differentiation. The EU Common Agricultural Policy defines agriculture as “multifunctional” and among the different roles and functions expected, there is also the “social function”, defined as the ability that the farm has to generate services with respect to a population with risk of social exclusion. This paper investigated all the agricultural initiatives with social impacts that were carried in the lands confiscated from the organized crime (called mafia), mainly in the South …

A new approach in the monitoring of the phytosanitary conditions of forests: the case of oak and beech stands in the Sicilian Regional Parks.

2016

The objective of this study was to investigate the health conditions of oak and beech stands in the three Regional Parks of Sicily (Etna, Madonie and Nebrodi). A total of 81 sampling areas were investigated, 54 in oak stands and 27 in beech stands. The phytosanitary conditions of each tree within the respective sampling area was expressed with a synthetic index namely phytosanitary class (PC). Oak stands showed severe symptoms of decline, with 85% of the sampling areas including symptomatic trees. In general, beech stands were in better condition, with the exception of Nebrodi Park, where trees showed severe symptoms of decline. On oak trees, infections of fungal pathogens were also observe…

Il controllo degli insetti fitofagi nell'olivicoltura biologica.

2016

Puntuali strategie di controllo, campionamenti personalizzati e maggiore consapevolezza entomologica, insita nell’approccio del coltivatore biologico, consentono ottimi risultati quali-quantitativi ed economici nella difesa fitosanitaria in olivicoltura “organica” e in qualsiasi area olivicola italiana. Le minori spese fitosanitarie rispetto all’olivicoltura convenzionale inducono un sempre maggior numero di produttori alla conversione verso il bio. Gli autori illustrano le metodologie ammesse e consigliabili in regime di agricoltura biologica, per il controllo dei principali insetti fitofagi del olivo nel Mediterraneo, con particolare riferimento alla mosca delle oilve, Bactrocera oleae, e…

Biodeterioration

2022

The biodeterioration of organic and inorganic materials, as well as polymers, is a complex of alteration processes induced by the growing and metabolic activity of organisms. It can be recognized on monuments, wall paintings, stone, wood, paper, vegetal/animal fibers, and parchment artworks. As defined by Hueck, 1968, biodeterioration is “any undesirable change in the properties of a material caused by the vital activities of organisms”; this definition is accepted as the meaning of the phenomenon. Both macroorganisms (such as animals, plants, and mosses) and microorganisms (such as autotrophic or heterotrophic bacteria, microfungi, cyanobacteria, algae, and lichens) represent the triggers …

SAMPLING DESIGN IN SHARE WAVE 7

2019

This chapter documents the sampling design adopted in SHARE. Starting with a definition of the SHARE target population, we describe the protocol that is followed to harmonise and document the sampling procedure and present the sampling frames used by the countries that recruited a baseline or refreshment sample in Wave 7. We then discuss some important aspects of the SHARE sampling design, such as stratification, clustering, variation in selection probabilities and sample composition. Finally, we provide additional information about the sampling variables included in the released SHARE dataset.
