Managing adoption by cultural development: Exploring the plant level effect of a ‘Company Specific Production System’ (XPS) in a Norwegian multinatio…

2020

Purpose: ‘Company Specific Production Systems’ (XPS) aim to adopt ‘best practice’ across plants within a company. A pertinent issue in the literature involves the constraints in the possibilities of realising such an adoption. This paper addresses to what extent and how a Norwegian multinational succeeded in adopting the XPS in its local plants. Design/methodology/approach: A Brazilian, Chinese and Norwegian plant of a Norwegian electro-chemical company were studied from 2017 to 2019. Our data consist of the results of the plant’s assessment performance program, combined with interviews and observations at different organizational levels. Findings: The MNC had largely managed to adopt the X…

Development and Validation of First Version of a Questionnaire for Measuring Pre-Service Primary Teachers' Science Content Knowledge

2016

A first version of an instrument to assess science conceptual knowledge in pre-service primary teachers is elaborated and validated. A multiple-choice test with 50 items was proposed. Four content areas of science from the curriculum of Primary Education in Spain were considered: natural environment and its conservation, biological diversity, health education and the human body, matter and energy. A sample of 83 pre-service teachers from a spanish university participated in the statistical validation process. Both external consistency (Test-Retest correlation) and internal consistency (Kurder-Richardson's 20th formula) were above 0.7. Item difficulty and discrimination indices were analysed…

Test-Bed Evaluation of CA and CF via a Software Defined Radio

2019

In Chaps. 3 and 4, we presented the analytical models and simulation approaches to study the impact of CA and CF on traffic flows in the single-flow single-user and the single-flow multi-user systems. In this chapter, we investigate the impact of CA and CF in a test-bed. We employ a software defined radio (SDR) from National Instruments (NI) to evaluate the performance of a CR system with user datagram protocol (UDP) flows. The adopted SDR is based on LTE protocol stack with additional functionalities that can support CA and CF, and accommodating PUs. By conducting measurements based on the test-bed system, we will be able to confirm that performance improvement can indeed be obtained by ap…

Atipicità e sistemi probatori: linee per una fenomenologia generale

2018

Il contributo esplora la categoria dell’atipicità probatoria disegnandone le linee di una fenomenologia generale: dalla piattaforma concettuale tradizionale dell’atipicità si muove verso l’esplorazione dei fenomeni di liquidità probatoria in rapporto all’irruzione delle tecnologie avanzate nell’accertamento giudiziario penale; gli interscambi tra prassi, giurisprudenza e normazione in tema di captatore informatico offrono, in tal senso, un osservatorio privilegiato, consentendo di saggiare la tenuta del modello.

EFFETTO DELL’ATTRITO NELL’AVANZAMENTO DELLA DELAMINAZIONE PER MODO II DI CARICO

2011

Il lavoro valuta l’influenza della dissipazione energetica dovuta agli effetti attritivi che si sviluppano all’interfaccia tra le lamine di provini sollecitati a Modo II di carico. Sono state effettuate diverse prove sperimentali su compositi in fibra di vetro e resina epossidica soggetti a condizioni di carico cicliche e valore medio crescente, tali da mantenere le lamine del composito in continua aderenza. Al fine di valutare l’incidenza dell’attrito interlaminare nella delaminazione per Modo II, i risultati delle prove sperimentali sono stati riprodotti per mezzo di analisi agli elementi finiti utilizzando il programma di calcolo FEAP (con codice sorgente aperto), nel quale è stato imple…

EFFETTO DELLA PRESSURIZZAZIONE DEI FORI E DELL’INDENTAZIONE ANULARE SULLA VITA A FATICA DI PROVINI IN LEGA DI ALLUMINIO

2011

Nel lavoro è investigato il comportamento a fatica di lastre forate in lega di alluminio. In particolare è valutata l‟influenza combinata dell‟espansione a freddo dei fori e dell‟indentazione sul miglioramento della vita a fatica. A tal fine sono state condotte diverse prove di fatica aventi lo scopo di valutare il numero di cicli a rottura e la conseguente curva di Wöhler. I risultati sperimentali sono stati confrontati con quelli ottenuti senza la realizzazione di alcun processo di espansione e di espansione-indentazione. Lo studio ha permesso di concludere che il processo di espansione ed indentazione anulare determina un ritardo nella nascita della cricca e della conseguente rottura a f…

Mineralogical and Chemical Records of Icelandic Dust Sources Upon Ny-Ålesund (Svalbard Islands)

2018

This work aims to identify the geochemical and mineralogical markers of Icelandic dust and to differentiate it from the dust of local origin deposited at the Ny-Ålesund station. We characterized representative sediment samples from Iceland and Svalbard and compared them to a set of aerosol samples collected in Ny-Ålesund to check the existence and type of the mineralogical markers. The sediment samples were analyzed by X-ray diffraction (XRD) to detect the mineralogical constrain of the geochemical markers. Both aerosol and sediment samples were examined by scanning electron microscopy coupled with EDS microanalysis (SEM-EDS) and image analysis to detect and to provide a morpho-chemical cha…
