The Role of Work-Nonwork Boundary Management in Work Stress Recovery
2016
The aim of the present study conducted among 1,106 Finnish employees was to identify boundary management profiles based on cross-role interruption behaviors from work to nonwork and from nonwork to work. Adopting a person-oriented approach through latent profile analysis, 5 profiles were identified: Work Guardians (21% of the employees), Nonwork Guardians (14%), Integrators (25%), Separators (18%), and an Intermediate Group (22%). We then examined differences between these profiles with respect to recovery experiences ( psychological detachment from work, relaxation, mastery experiences, and control during off-job time) and recovery outcomes (vigor and exhaustion). Work Guardians had the po…
Genesi geometrica delle volte centriche
1996
Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…
The influence of the anatase nanoparticles boundaries on the titania activity performance
2014
Metal oxides structures, formed by ordered self-assembling of crystalline nanoparticles aggregates, are attracting growing attention in fields such as catalysis or solar cells. The properties of these structures are influenced not only by their morphology and nanoparticles composition but also by the assembled particles boundaries. In order to determine the influence of these boundaries on the structures properties, the present investigation has been devoted to study the characteristics of anatase nanoparticles boundaries in titania aggregates prepared by TiCl4 hydrolysis at low temperature. Proton magic angle spinning nuclear magnetic resonance and high resolution transmission electron mic…
Eliminating Artificial Boundary Conditions in Time-Dependent Density Functional Theory Using Fourier Contour Deformation
2023
We present an efficient method for propagating the time-dependent Kohn-Sham equations in free space, based on the recently introduced Fourier contour deformation (FCD) approach. For potentials which are constant outside a bounded domain, FCD yields a high-order accurate numerical solution of the time-dependent Schrödinger equation directly in free space, without the need for artificial boundary conditions. Of the many existing artificial boundary condition schemes, FCD is most similar to an exact nonlocal transparent boundary condition, but it works directly on Cartesian grids in any dimension, and runs on top of the fast Fourier transform rather than fast algorithms for the application of …
The Need-Adapted Approach in Psychosis: The Impact of Psychosis on the Treatment and the Professionals
2014
Psychosis is a challenging phenomenon for professionals. In the need-adapted approach (NAA), therapy meetings constitute a deliberate effort to meet the challenges by bringing all the main parties together within a common discussion. The aims of this study are to analyze and evaluate psychiatrists' experiences of the treatment processes in psychosis. A qualitative multiple case study approach has been used. Between August 2007 and January 2009, co-research interviews (CR-Is) and stimulated-recall interviews (STR-Is) with 10 psychiatrists from 3 different parts of Finland were videoed and transcribed verbatim. The material was analyzed using qualitative content analysis. The difficult emotio…
Foreste a tavola:i consumi alimentari inducono la crescente deforestazione tropicale e sub-tropicale anche in Italia
2021
L’agricoltura costituisce da sempre una grande minaccia per gli ecosistemi naturali del nostro pianeta,e non solo in quanto attività umana essenziale per la produzione di cibo. Attualmente, in particolarenella regione tropicale e sub-tropicale, le attività agricole sono fattori di pressione cruciali per il mantenimentodei cicli di vita di ecosistemi essenziali per la biosfera, complessi e resilienti, come le foreste. Lesocietà contemporanee, essenzialmente urbane e sempre più disconnesse dai processi naturali ed ecologici,tendono a dimenticare, o semplicemente non considerare, le responsabilità di queste pressioni insostenibili.Tra le maggiori cause di deforestazione, quattro commodities ri…
Social worlds and symbolic boundaries of cannabis users in Poland
2022
Many legislations and cultures undergo liberalization regarding cannabis use, and users in Poland make constant references to, and are part of, a burgeoning global cannabis culture. Still they have to relate to conservative drug discourses and legal frameworks. This paper explores this discrepancy between users’ experience on the micro level and the macro context in which they live. The aim is to explore the boundary making processes cannabis users engage in to detach themselves from punitive legislation and conservative social reactions. The concept of social worlds is used to theorize and better understand their situation. The boundaries between the users’ social worlds are analyzed with …
The effect of organizational separation on individuals' knowledge sharing in MNCs
2017
Abstract The ability of an organization to apply knowledge globally has been conceptualized as critical for the existence of multinational corporations (MNCs). We argue for an organizational separation effect on knowledge sharing that challenges the view of the MNC as a latent social community. Using a unique data-set of more than 4000 individual responses from an MNC, Telenor, we test how three types of drivers for individuals’ knowledge sharing – individuals’ motivation, and individuals’ perceptions of organizational values and organizational work practices – work differently within, as opposed to across, business units. Our analysis suggests that while intrinsic motivation, innovative va…
An agency-promoting learning arena for developing shared work practices
2017
Despite the emerging recognition of the pivotal role played by professional agency within work contexts, little is known about how agency is promoted and enacted in organised work-related learning settings. This chapter focuses on the work conference as an orchestrated agency-promoting learning arena. We understand professional agency as a necessary precondition of work-related learning, and we emphasise the potential of work conferences to activate and promote such agency. Our empirical study investigated three work conferences in education and healthcare organisations in Finland. Utilising assessments, the investigation addressed how the participants perceived the conditions for learning …
Spazi e tempi dell’educare tra casa e scuola: note di pedagogia fondamentale alla luce della pandemia
2021
Among the most immediate consequences of the spread of the COVID-19 pandemic, the need to rethink all the spaces of daily life and, therefore, also those of education, particularlly has emerged. The unprecedented difficulties in managing the times and spaces of educating have made it no longer possible to postpone a careful pedagogical reflection on them: from a phenomenological perspective, this means trying to describe, starting from the experiences of lived times and spaces, how much remains essential in the experience of educating between school and home before the pandemic, and what turned out to be accidental or even uneducational. In this perspective, the text launches some ideas for…
