Does innovativeness reduce startup survival rates?
2015
There are two competing hypotheses explaining how innovativeness influences the survival of startups: On the one hand, innovativeness is argued to foster survival-enhancing attributes (e.g., market power and cost efficiency) and capabilities (e.g., absorptive capacity). On the other hand, an innovative startup faces (and bears the associated risks of) liabilities of newness and smallness that exceed those of its non-innovative counterparts. The available empirical literature addressing this theoretical tension mostly supports the former hypothesis; we suggest that this finding is, in part, driven by the common practice of employing an ex post measure that already embodies a degree of succes…
Scaffolding through dialogic teaching in early school classrooms
2016
The present study examines what types of dialogic teaching patterns can be identified in the early school years, and how teachers scaffold children's participation and shared understanding through dialogic teaching. Thirty recorded lessons from preschool to Grade 2 in Finnish classrooms were analysed using qualitative content analysis. Two teacher-initiated and two child-initiated dialogic teaching patterns were identified. Teacher's scaffolding in teacher-initiated dialogues was characterised by high responsibility in maintaining the interactional flow and utilisation of diverse strategies. In the child-initiated dialogues, the teachers' scaffolding consisted of listening and inquiry, and …
Quality of educational dialogue and association with students’ academic performance
2018
The study used a mixed-methods approach to examine the associations between the quality of educational dialogue and students' academic performance and to analyse what kinds of dialogic teaching patterns of different levels of quality can be identified in classroom lessons. A total of 158 Grade 6 lessons were video-recorded, and the quality of the educational dialogue was assessed using the Classroom Assessment Scoring System-Secondary (CLASS-S) observational instrument. Multilevel modelling indicated that the quality of educational dialogue was positively associated with students’ academic performance (grades) in language arts and physics/chemistry. Qualitative analysis was subsequently use…
Transmission delay in technology-mediated interaction at work
2015
This paper investigates transmission delay in technology-mediated interaction from a participant’s perspective. The approach chosen here contrasts with previous studies of delay: only what is seen, heard and done at one end (i.e., what is available on screen) is considered in the analysis. It is argued that participants themselves lack access to the other sides of their interactions as they unfold at remote locations, and they thus cannot observe and deal with delay from an outside perspective. Analyzing single cases of delay-ininteraction within the framework of conversation analysis, the focus is on dispersed conversation partners’ resources to detect a problem, and to make visible and re…
Mobile phones, identity and discursive intimacy
2005
This paper deals with the sociocultural effects of mobile phones in Philippine society. In particular it looks at how mobile phones have affected notions of identity and the rise of the sexual subject. It also deals with the political possibilities and implication of this new communicative technology in a society with previously poorly developed telephonic and other communicative technologies. Mobile phones allow absent subjects to exercise a daily presence in their communities of origin. This absent presence generates virtual subjects interacting primarily via the mobile phone.
Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metalorganic frameworks for the catalytic hydrogenation of CO 2
2021
[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very powerful tool for tuning optical and catalytic properties. However, accessing different stoichiometries is not always synthetically possible. Here, we show that the thermal decomposition of the recently reported metal-organic framework MUV-101(Fe, Ti) results in the formation of carbon-supported titanomaghemite nanoparticles with an unprecedented Fe/Ti ratio close to 2, not achievable by soft-chemistry routes. The resulting titanomaghemite phase displays outstanding catal…
Modified Glasgow Prognostic Score is Associated With Risk of Recurrence in Bladder Cancer Patients After Radical Cystectomy
2015
Recently, many studies explored the role of inflammation parameters in the prognosis of urinary cancers, but the results were not consistent. The modified Glasgow Prognostic Score (mGPS), a systemic inflammation marker, is a prognostic marker in various types of cancers. The aim of the present study was to investigate the usefulness of the preoperative mGPS as predictor of recurrence-free (RFS), overall (OS), and cancer-specific (CSS) survivals in a large cohort of urothelial bladder cancer (UBC) patients.A total of 1037 patients with UBC were included in this study with a median follow-up of 22 months (range 3-60 months). An mGPS = 0 was observed in 646 patients (62.3%), mGPS = 1 in 297 pa…
Structuration du territoire bourguignon : de l'île à l'isthme
2006
Three principles govern the structuration of the burgundian territory. Its internal organization, with the peripheral location of its most active areas, is similar to the organization of an island. Its situation within national and European space makes it an area of multiple transitions, an unsettled organization, submissive to strong centrifugal forces which can threaten its unity. Lastly, it has always been crossed by numerous links, it is an intermediate space between nodes, strongly marked with networks and exogenous traffic which criss-cross its territory.
Search for photonic signatures of gauge-mediated supersymmetry in 8TeV pp collisions with the ATLAS detector
2015
A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of 20.3 fb[superscript −1] of proton-proton collision data at √s = 8 TeV recorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating an isolated photon and significant missing transverse momentum are explored. These signatures include events with an additional photon, lepton, b-quark jet, or jet activity not associated with any specific underlying quark flavor. No significant excess of events is observed above the Stand…
Modelli per l'interpretazione dei risultati di prove di push-out su travi reticolari miste
2011
Il comportamento sotto carico delle travi prefabbricate reticolari miste prima della pubblicazione delle nuove norme tecniche sulle costruzioni, veniva solitamente interpretato in analogia a quello di travi in c.a o a quello di travi miste acciao-calcestruzzo classicamente intese. L’esplicito riferimento nelle attuali norme a questa tipologia che viene trattata in un capitolo a parte, ha fatto scaturire l’esigenza di chiarezza e come conseguenza la pubblicazione di Linee Guida emanate dal C.S.LL.PP. che classificano le diverse tipologie in tre categorie: a) strutture composte acciaio-calcestruzzo; b) strutture in c.a. o in c.a.p.; c) strutture non riconducibili alle due categorie precedenti…
