Proof of multilayer structural organization in self-assembled polycation-polyanion molecular films
1994
Abstract Multilayer organization of ultrathin polycation-polyanion self-assembled films is demonstrated using two approaches. (1) Fabrication of polyion superlattices with alternation of three different polyelectrolytes in (ABCB) n fashion, which gives rise to a Bragg peak in X-ray reflectivity. The spacing d=93.4 A corresponds to the repeat unit (ABCB) n . (2) Drying-induced manipulation of the film surface at regular intervals. Normally the layer-by-layer adsorption is carried out by keeping the film wet throughout all deposition cycles. Alternatively the film surface can be manipulated by gently drying the film in a stream of nitrogen or air after the adsorption of every layer. When the …
An Improved Empirical Relation to Determine the Particle Number Density of Fluid-Like Ordered Charge-Stabilized Suspensions
2001
Polystyrene as an archetypal charge-stabilized colloid model system was used in this work under well defined preparation conditions. A continuous preparation technique was used to control the suspension parameters salt concentration c and particle number density n. Measurements of n were performed using both conductivity in the completely deionized state and static light scattering. We found a significant deviation between the position of the first maximum of the static structure factor qmax=2π/L and an estimate identifying the relevant length scale L with the average inter-particle distance d¯=n−1/3. Instead, qmax was observed to follow the relation qmax=(2.20±0.03)π/d¯, which is equivalen…

The unspeakable through the works of some contemporary Spanish composers
2016
The concept of unspeakable, as complex as it may be, can base itself on an experience of the sensitive, and find a common context in the events exceeding the limit and pointing a certain chaos. Those of the Spanish Civil War have constituted, by numerous aspects, examples of these unthinkable excesses. The impact of the environment on the creators has been heard in the thematic traces which are imperative in the works composed on the themes of death, violence or war: from the sound phenomena, some figures making sensitive the exceeding of the limit and chaotic connotation have been highlighted and echo what is beyond belief, as the destruction of man or the inaudibility of death. These figu…
Vironkielisten osallistujien kielitaito Yleisten kielitutkintojen suomen kielen testissä
2021
Tarkastelemme tässä artikkelissa vironkielisten suomen oppijoiden osallistumista Suomen kansallisen kielitestin, Yleisten kielitutkintojen, keskitason tutkintoon ja heidän kielitaitoprofiiliaan tutkintotulosten valossa. Vertaamme tuloksia yleiseen tutkintomenestykseen sekä osallistujien taustaan ja pohdimme suomen kielen asemaa oppimisen kohteena vironkielisten näkökulmasta. Analyysimetodina käytämme kuvailevaa tilastollista analyysia sekä tilastollista päättelyä. Tulokset osoittavat, että vironkieliset osallistujat menestyvät tutkinnossa hyvin ja erityisesti ymmärtämistaidot ovat tutkitussa ryhmässä vahvat. Vaikka aiemman tutkimuksen valossa suomen kielen taidon tason onkin nähty riippuvan…
Emotional intelligence as a mediator in the relationship between neuroticism and L2 achievement
2020
Abstract The present study investigates the interaction of the higher-order personality trait of Neuroticism and the lower-order personality trait of Emotional Intelligence (trait EI) in the context of foreign language acquisition (FLA). A mediation model was applied to explore the pathway from Neuroticism via trait EI to self-rated L2 skills. The reported results show that the trait EI is not only a significant predictor of the self-reported L2 speaking proficiency, but also a mediator in the relationship between Neuroticism and self-rated L2 speaking proficiency. Consequently, trait EI could be regarded as an important variable in the FLA context because its positive impact on self-percei…
The Syntax–Pragmatics Interface in Heritage Languages: The Use of anche (“Also”) in German Heritage Speakers of Italian
2023
This paper deals with the use of anche (“also”) by German heritage speakers of Italian (“IHSs”). Previous research showed that anche and its German counterpart auch share many features but also display language-specific characteristics. According to previous research on bilingualism, heritage speakers show cross-linguistic influence (“CLI”) when a linguistic phenomenon is at the syntax–pragmatics interface and there is a partial overlap in the two languages at stake. Therefore, we expect the use of anche in IHSs to be influenced by CLI. By analysing data from a semi-spontaneous corpus, we investigate the production of anche in order to understand which factors shape the grammar of the IHSs.…
Negotiation of expertise and multifunctionality : PowerPoint presentations as interactional activity types in workplace meetings
2016
This article investigates exchanges between the presenter and another participant within PowerPoint presentations in workplace meetings. Using ethnomethodological conversation analysis as a method, it examines 1) how participants orient to each other's expertise, 2) what is accomplished through the exchange and 3) how the PowerPoint slide is interwoven with the process. The results show how the exchanges establish the presentation as information delivery in which the complexity of professional knowledge is displayed and negotiated. Moreover, there is an orientation to directive functions of the presentation activity. The PowerPoint slides as a text and as a material object are evoked for th…
Idiomatic intonation and forensic phonetics: sociolinguistic and dialectal information from intonation in Spanish
2015
Las investigaciones de carácter geoprosódico realizadas sobre el español y sus variedades ponen en evidencia que la entonación puede reportar importantes beneficios a la fonética forense, ya que esta lleva asociada información de carácter dialectal y sociolingüístico de especial relevancia sobre el individuo –grupo sociocultural al que pertenece, origen geográfico, medio social en el que se inserta–, además de otros rasgos, cualidades o circunstancias como la edad, el sexo, o incluso su temperamento, carácter o estado de ánimo. Para ello se hace necesario no solo saber qué parámetros acústicos suprasegmentales son relevantes para la identificación del hablante, sino también analizar la vari…
"Vierasta korostusta on niin vähän, että arvaan viro" : yleisten kielitutkintojen suomen kielen arvioijien käsityksiä suomenruotsalaisten puhumasta s…
2022
Artikkelissa tarkastelemme Yleisten kielitutkintojen suomen kielen arvioijien (N = 44) käsityksiä suomenruotsalaisten puhujien (N = 9) oletetusta ensikielestä. Tutkimuksemme aineisto perustuu Suomen Akatemian rahoittamaan Rikkinäistä Suomea: Aksenttien arviointi yhteiskunnallisena portinvartijana (2018– 2022) -hankkeeseen, jossa tutkitaan vieraan aksentin vaikutusta suullisen kielitaidon arvioinnissa. Analysoimme sisällönanalyysin avulla arvioijien kirjallisia vastauksia liittyen puhujien ensikieleen ja siihen liittyviin perusteluihin. Artikkelissa kuvaamme, miten usein ja miksi suomen kielen arvioijat pitivät suomenruotsalaisia suomen kielen puhujia virolaisina puhujina. Arvioijat tunnisti…
