The Development of Territorial Cohesion Policies in Latvia

2011

Abstract This article examines how territorial cohesion policies have taken shape in Latvia in response to European debates on the subject. It argues that the conceptualization of territorial cohesion in Latvia is closely linked to the country's historical development path and primarily reflects national concerns with social cohesion. While Latvian national and regional level institutions rely on open processes of policy-making and stakeholder involvement, which were developed during the period of post-soviet transition when the country's planning system and regional policy approach were reformulated, the same open and consultative approach is not always evident during the drafting or consi…

Physical Activity Tracker Application in Promoting Physical Activity Behavior among Older Adults : A 24-month Follow-Up Study

2022

Objectives To investigate whether and how PA tracker application use supports PA behavior among older adults during the first 24 months of use. Methods: The changes in PA levels (i.e., time spent in different PA intensities) and between PA categories (i.e., low, moderate, or high based on total PA) were examined between three different time points: before taking the application into use (t0), after 12 months of use (t1), and after 24 months of use (t2). The data was collected by using the International Physical Activity Questionnaire modified for the elderly (IPAQ-E). Results: A statistically significant increase was observed in walking (χ2 (2) = 29.741, p < .001), moderate PA (χ2 (2) =…

Collaborative Policy Making and Stakeholder Engagement: A Resident–Based Perspective

2019

This study analyses residents’ perceptions and attitudes towards tourism and community engagement with tourism planning. Overall, residents think that the positive effects of tourism development outweigh the negative impacts. Despite this, they express concerns regarding the economic future of their area and that the tourism development in their area is mostly exogenously driven. Further, they do not feel involved in tourism planning but, quite surprisingly, they do not seems to be convinced that local authorities should encourage community participation in tourism decision making. Exploratory factor analysis and hierarchical and non-hierarchical cluster analysis were therefore conducted. F…

Stakeholders’ Attitudes about the Transplantations of the Mediterranean Seagrass Posidonia oceanica as a Habitat Restoration Measure after Anthropoge…

2021

Anthropogenic impacts on Posidonia oceanica meadows have led to a decline of this ecosystem throughout the Mediterranean. Transplantations have often been prescribed as a compensation measure to mitigate the impacts caused by coastal maritime works. Here a Q methodology approach was used to investigate the stakeholders’ attitudes in four case studies of P. oceanica transplants realized in Italian waters. Twenty-two respondents were asked to score 37 statements, and the resultant Q-sorting was analyzed via an inverse PCA using the KADE software. Four discourses, corresponding to the significant axes in the factorial analysis were identified: science and conservation (F1), oriented at a rigor…

Lamb shift of a uniformly accelerated hydrogen atom in the presence of a conducting plate

2009

We investigate the effects of acceleration on the energy-level shifts of a hydrogen atom interacting with the electromagnetic field and in the presence of an infinite perfectly conducting plate. We consider the contributions of vacuum fluctuations and of the radiation reaction field to the Lamb shift, and we discuss their dependence from the acceleration of the atom. We show that, because of the presence of the boundary, both vacuum field fluctuations and radiation reaction field contributions are affected by atomic acceleration. In particular, the effect of the vacuum field fluctuations on the energy-level shifts is not equivalent to that of a thermal field. We also discuss the dependence …

Effects of a uniform acceleration on atom–field interactions

2014

We review some quantum electrodynamical effects related to the uniform acceleration of atoms in vacuum. After discussing the energy level shifts of a uniformly accelerated atom in vacuum, we investigate the atom-wall Casimir-Polder force for accelerated atoms, and the van der Waals/Casimir-Polder interaction between two accelerated atoms. The possibility of detecting the Unruh effect through these phenomena is also discussed in detail.

van der Waals interactions between excited atoms in generic environments

2015

We consider the the van der Waals force involving excited atoms in general environments, constituted by magnetodielectric bodies. We develop a dynamical approach studying the dynamics of the atoms and the field, mutually coupled. When only one atom is excited, our dynamical theory suggests that for large distances the van der Waals force acting on the ground-state atom is monotonic, while the force acting in the excited atom is spatially oscillating. We show how this latter force can be related to the known oscillating Casimir--Polder force on an excited atom near a (ground-state) body. Our force also reveals a population-induced dynamics: for times much larger that the atomic lifetime the …

La parziale divergenza di interessi tra gli shareholder nella formulazione della strategia aziendale

2020

La storia economica del secolo scorso ha mostrato come specializzazione del lavoro, da un lato, e la necessità di suddividere il rischio tra più investitori, dall’altro lato, abbiano spinto al “divorzio” o, meglio, alla separazione tra la proprietà e il controllo di molte aziende. Esplorando le conseguenze della separazione tra la proprietà e il controllo, gli studi di corporate governance, tradizionalmente, hanno messo in luce i possibili conflitti tra manager e azionisti, denominati conflitti principal-agent. Inoltre, gli studi precedenti hanno riconosciuto la distribuzione della proprietà come un meccanismo utile ad alleviare suddetti conflitti. Il presente capitolo discute criticamente …

Determinants to the Use of Business Process Modeling

2010

This article addresses a theoretical gap in the BPM literature on factors that influence the acceptance of process modeling (PM) in organizations. Literature review on PM and 34 qualitative interviews were combined into a PM acceptance model and empirically tested with data from 74 companies showing that PM is to a large extent a mandated activity, explaining the missing link between PM attitudes on PM intention. The study extends the TAM and the TPB to the context of process modeling and demonstrates that less studied socio-political factors in addition to awareness of PM are important to understand PM acceptance. The findings show that social influence from different stakeholder reference…
