The Role of Leadership in Complex Strategic Networks: Enabling Effect Versus Emergence

2013

In today's knowledge-based economy, the sources of competitive advantage lie more and more in webs of interactions among a variety of actors (such as firms, universities, research organizations, government institutions and so on), that over time originate the emergence of strategic networks. The paper aims to shed light on the determinants of network interaction and the ensuing processes of knowledge and resource transfer and circulation, on which the networkbased sources of competitive advantage are rooted. Accordingly, by means of the adoption of the complexity system perspective, on the one hand, we underscore the emergent nature of network interactions stemming from the self-organizing …

Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM

2014

Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…

Tryptophan metabolic pathways and brain serotonergic activity: A comparative review

2019

The essential amino acid L-tryptophan (Trp) is the precursor of the monoaminergic neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Numerous studies have shown that elevated dietary Trp has a suppressive effect on aggressive behavior and post-stress plasma cortisol concentrations in vertebrates, including teleosts. These effects are believed to be mediated by the brain serotonergic system, even though all mechanisms involved are not well understood. The rate of 5-HT biosynthesis is limited by Trp availability, but only in neurons of the hindbrain raphe area predominantly expressing the isoform TPH2 of the enzyme tryptophan hydroxylase (TPH). In the periphery as well as in brain areas …

Nomierinošo bezrecepšu medikamentu un uztura bagātinātāju lietošana un aprite aptiekā

2020

Mūsdienu dzīvi raksturo cilvēka adaptācijas nepieciešamība pēc strauji mainīgu sociālo un tehnoloģisko nosacījumu ietekmes. Mainīgie dzīves apstākļi nereti ir stresa cēlonis. Stress ir cilvēka reakcija uz jebkādiem notikumiem, kas pārsniedz tā adaptācijas iespējas. Bakalaura darba mērķis bija aplūkot nomierinošo preparātu sastāvdaļas, izpētīt lietošanas paradumus dažādās vecuma grupās, salīdzināt pārdošanas apgrozījumu par 2017.gadu, 2018.gadu un 2019.gadu, noskaidrot kuri preparāti ir vispieprasītākie. Pēc apgrozījuma rezultātiem ir redzams, ka ar katru gadu nomierinošo preparātu apgrozījums pieaug. Populārākais medikaments ar nomierinošo efektu ir Sirds pilieni RFF 90 ml un populārākais u…

Examining the longitudinal relationship between visibility and persistence on stress and technology-assisted supplemental work

2023

This study examines the longitudinal relationship between two affordances of organizational information and communication technologies (ICTs)—that is, visibility and persistence—and individuals’ subjective stress and technology-assisted supplemental work (TASW). We propose that visibility and persistence associated with organizational ICTs are often more aptly construed as probabilities for action, rather than merely possibilities for action. The hypotheses are tested using latent change structural equation modeling drawing on two-wave survey data from 437 employees of a global industrial logistics company headquartered in a Nordic country. The findings highlight that visibility is associat…

Plio-Pleistocene strike-slip deformation in NE Sicily: the example of the area between Capo Calavà and Capo Tindari

2005

The Peloritani Mts. in Northeastern Sicily are part of the Sicilian orogenic belt interposed between the Tyrrhenian basin and the Ionian Basin. In the Tyrrhenian basin crustal thinning has been active since the late Miocene, whereas wedge accretion (External Calabrian Arc) has occurred in the Ionian basin, due to the north-westward subduction of the Ionian Plate below the Calabrian-Peloritani Arc. Strike-slip tectonics in NE Sicily occurred during Plio-Pleistocene times. Faulting caused a non-uniform uplift rate of the Plio-Pleistocene deposits, which are elevated up to 500 m above sea level. The structural pattern is mainly represented by NW-SE and N-S/NNE-SSW trending transcurrent faults …

Investigating the Structural Properties of an IT-Enabled Resource

2019

The synergistic combination and integration of information technology (IT) and other complementary organizational resources to form IT-enabled resources, has long been identified as one means through which organizations can derive benefits from IT. However, research shows that the integration required to form IT-enabled resources from which organizations derive benefits, also constrains the renewal and redeployment of the IT-enabled resources to address new strategic imperatives. Thus, there are several calls for further research on how organizations can sustain the derivation of benefits from IT especially in dynamic environments. This study responds to such calls. Specifically, it draws o…
