Nonlinear beam self-cleaning in a coupled cavity composite laser based on multimode fiber
2017
International audience; We study a coupled cavity laser configuration where a passively Q-switched Nd:YAG microchip laser is combined with an extended cavity, including a doped multimode fiber. For appropriate coupling levels with the extended cavity, we observed that beam self-cleaning was induced in the multimode fiber thanks to nonlinear modal coupling, leading to a quasi-single mode laser output. In the regime of beam self-cleaning, laser pulse duration was reduced from 525 to 225 ps. We also observed a Q-switched mode-locked operation, where spatial self-cleaning was accompanied by far-detuned nonlinear frequency conversion in the active multimode fiber.
Upper limits on the isotropic gravitational-wave background from Advanced LIGO and Advanced Virgo's third observing run
2021
We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. Unlike in previous observing runs in the advanced detector era, we include Virgo in the search for the GWB. The results are consistent with uncorrelated noise, and therefore we place upper limits on the strength of the GWB. We find that the dimensionless energy density $\Omega_{\rm GW}\leq 5.8\times 10^{-9}$ at the 95% credible level for a flat (frequency-independent) GWB, using a prior which is uniform in the log of the strength of the GWB, with 99% of the sensitivity comi…

From the Shadow of a Myth to an Academic Subject : Teaching Writing from a Cognitive Base
2021
In order to truly understand one’s teaching methods and share them with others, one first needs to understand what has been done in the past. The aim is to become conscious of habits, models and attitudes that have become a part of local lore – either in studies of creative writing or in the education system in general. One way to do this is to read creative writing guides written in different periods of time. This paper examines Finnish writing guides published since 1900. It also shows how teaching creative writing slowly became possible in Finland. Finally, the article describes how the historical situation, writing guides and academic tradition influenced the practice of teaching writin…
Does communal context bring the worst in narcissists?
2014
The present experiment (N = 95) investigated the relations of narcissism with social value orientation under facade conditions of testing communal or agentic traits (or none – in a control condition). The results indicated that narcissism predicted less willingness to share resources with others and more competitive orientation in a facade communal condition compared to the remaining two conditions: control and agentic. The results confirm narcissistic disregard for communal domain and are consistent with the extended agency model of narcissism and the “success as a drawback” effect.
Improving the Quality of the Comply or Explain Approach and Introducing Self-Monitoring Through Online Feedbacks
2017
Codes of corporate governance and comply or explain approach are always at the core of the European Union agenda. This paper will deal both with the evolution of codes of corporate governance across Europe, and with the 2014 Recommendation. The idea put forwards is that regulators, at both EU and national level, should mainly improve the environment where the comply or explain approach is applied and introduce a system of self-monitoring through online feedbacks only. Arguably, this proposal might offer Member States a light-touch way to comply with Art. 11 of the 2014 Recommendation laying down that “[i]n order to motivate companies to comply with the relevant corporate governance code or …
Reducing whole-body vibration exposure in backhoe loaders by education of operators
2012
Author's version of an article published in the journal: International Journal of Industrial Ergonomics. Also available from the publisher at: http://dx.doi.org/10.1016/j.ergon.2012.03.001 Whole-body vibration is a health hazard for operators of construction machinery. The level of whole-body vibration exposure on the operator is governed by three different factors; performance of the suspension system of the machine, planning of the work and the skills of the operator.In this research work it is investigated whether there is a potential in bringing down the level of whole-body vibration exposure by educating operators of backhoe loaders. This is carried out by an experimental setup. Six ex…
Consumer Information Services in Intercultural Tourism : An Ethnographic Study of Chinese Outbound Backpackers
2017
This paper reports the findings of an ethnographic study of Chinese outbound backpackers’ use and adoption of consumer information services (CIS) in an intercultural tourism setting. We apply McKenna et al.’s research model of consumers’ adoption of information services as the analytical lens for the interpretive qualitative study. The data gathering was conducted in four different countries. The findings of the study confirm linkages between four information service types and the use and adoption of CIS. The study also found that service types are more diversely linked than the earlier studies have predicted and therefore we propose a revised research model, which can be used for studying …
Optometriskie treniņi pacientiem ar idiopātisku nistagmu.
2020
Maģistra darbs ir uzrakstīts angļu valoda uz 47 lapām. Tas satur 28 attēlus, 2 tabulas un 42 atsauces uz literatūras avotiem. Maģistra darba mērķis ir nodemonstrēt optometrisko rehabilitācijas metožu ietekmi uz infantilu idiopātisko nistagmu (IIN). Desmit pacientiem ar IIN (30 ± 14 g.) tika veiktas sekojošas ārstēšanas metodes: prizmas ar bāzi uz āru, krāsotas kontaktlēcas (zīlītes diametrs 5 mm), audio-biofīdbeka metode. Pirms un pēc ārstēšanas tika novērtēts redzes asums un kontrastredze tālumā un stereoredze tuvumā ar labāko subjektīvo korekciju, nistagma apmlitūda un frekvence. Rezultāti parādīja, ka visas ārstēšanas metodes vienādi ietekmēja redzes asuma, nistagma amplitūdas un frekven…
El dinamismo conversacional: subsunción y feed-back. Carácter acumulativo de los elementos conversacionales
1992
Los estudiosos de la conversación coinciden en señalar el carácter especial de la relación que une a dos hablantes en un encuentro verbal. Nuestro objetivo en el presente estudio es profundizar un poco más en tales relaciones. Analizaremos, pues, algunos de los rasgos fundamentales a los que se subordina una toma de turno conversacional, como la relación que vincula al hablante y los oyentes, los canales de retroalimentación, la construcción colaborativa de los enunciados o la progresión acumulativa que caracteriza la información. Englobaremos todas estas cuestiones bajo el nombre genérico de dinamismo conversacional.
