Performing transnational family with the affordances of mobile apps : a case study of Polish mothers living in Finland

2020

Affordances provided by digital technologies and mobile apps (WhatsApp, Skype, Messenger) help in maintaining familyhood. These mobile apps enable the creation of in-app family groups. They also afford image sharing, which is used for phatic purposes. Digital connectivity provides the illusions of togetherness and belonging, and allows for performing family in a transnational context (emotional transnationalism). However, it also generates the feelings of guilt through infrequent communication. In the auto-driven visual elicitation interviews, the study looks at family constellations and technologically mediated communication from the perspective of five Polish mothers living in Finland. Ap…

Value added taxes on electronic commerce: Obstacles to the EU Commission’s approach

2000

While e-commerce is developing tremendously fast, domestic politics and legislation labour to keep up with the dynamics of the new technology. Among other things, fiscal law is a particularly explosive area. Here, the current proposal of the EU Commission is to apply the already existing value added tax to e-commerce. By doing so, the Commission hopes to prevent the massive threatened shortfall in tax revenue. How is this approach of the Commission to be judged? Are there any alternatives?

Suomen kielen oppimisen mahdollisuudet ja työyhteisön tuki puhdistuspalvelualalla: afrikkalaisten maahanmuuttajien käsityksiä ja kokemuksia

2013

This article presents a triple case study of African immigrants’ beliefs about Finnish language learning and support of the work community in the cleaning industry. Cleaning does not require a high language proficiency and it is therefore a typical first job for immigrants, a so-called entrance job. The theoretical framework of the study combines dialogical and sociocultural perspectives on language learning. Learners’ beliefs about work-related affordances and scaffolding are analysed using a dialogical analysis of beliefs. The interviewees’ shared belief is that in spite of their simple duties, cleaning work does provide affordances for learning, e.g. in the form of work-related announcem…

Currently, there are various definitions for extreme sports and researchers in the field have been unable to advance a consensus on what exactly constitutes an 'extreme' sport. Traditional theory-led explanations, such as edgeworks, sensation seeking and psychoanalysis, have led to inadequate conceptions. These frameworks have failed to capture the depth and nuances of experiences of individuals who refute the notions of risk-taking, adrenaline- and thrill-seeking or death-defiance. Instead, participants are reported to describe experiences as positive, deeply meaningful and life-enhancing. The constant evolution of emerging participation styles and philosophies, expressed within and across…

Concordance Analysis

2011

Background In this article, we describe qualitative and quantitative methods for assessing the degree of agreement (concordance) between two measuring or rating techniques. An assessment of concordance is particularly important when a new measuring technique is introduced.

Is measurement of the gingival biotype reliable? Agreement among different assessment methods.

2019

Background To determine agreement among the most commonly used methods for assessing the gingival biotype. Material and Methods An electronic survey was sent to a sample of dentists practicing in Spain. The questionnaire was based on the evaluation of 5 cases involving different gingival biotype assessment methods. Dentists were required to classify the cases as having a “thin”, “thick” or “not able to classify” biotype. Each case was assessed using a frontal intraoral photo of the anterior teeth; an enlarged photo of the buccal aspect of the tooth with a periodontal probe inserted inside the sulcus; and the real thickness measured in mm with a calibrated needle. Agreement among the classif…

Comparative evaluation of molecular methods for the quantitative measure of torquetenovirus (TTV) viremia, the new surrogate marker of immune compete…

2019

Background Torquetenovirus (TTV) viremia is emerging as a promising tool to assess functional immune competence, to predict posttransplant immune-related complications, and eventually to customize immunosuppression. Methods In this study, 327 blood samples were tested using two real-time PCR (rtPCR) assays both targeted to the untranslated region of the TTV genome. The first assay was an in-house rtPCR developed by our group, the second one was the recently marketed TTV R-GENE assay. Results In the validation study, the TTV R-GENE showed good performances in precision and reproducibility, and sensitivity as low as 12 TTV DNA copies/mL, like previously reported for the in-house rtPCR. The Bl…

Relationship and correspondence between different impact indicators in a sample of articles of excellence

2016

The objective was to compare the impact factor to 2 years of self-citations (IF2Y) with impact factor 2 years without self-citations (IF2YWS) and IF2Y with the impact factor to 5 years (IF5Y) as well as IF2YWS with SCImago Journal Rank (SJR) about journals where they were published articles of excellence in smoking by Spanish authors in the period 2008-2012. The search was conducted in the SCI-E and the SSCI-E on November 25, 2013. Were selected documents that had the h index of the strategy global sample (number of articles that have at least that number of citations) to search using the descriptors "smok ∗" OR "tobac ∗". A total of 69 articles by Spanish authors were recovered from 55 jou…

Investigation of lattice dynamical and dielectric properties of MgO under high pressure by means of mid- and far-infrared spectroscopy.

2013

We investigate the lattice dynamical and dielectric properties of MgO single crystals and powders by measurements in the mid- and far-infrared frequency region under high pressures, ranging up to 21.7 GPa. The shift of the restrahlen region is used to determine the pressure dependence of the transverse and longitudinal optical modes. The analysis of the refractive index in the mid- and far-infrared region allowed us to obtain the pressure behavior of the static and electronic dielectric constants. The transverse effective charge slowly decreases under high pressure, reflecting the stability of MgO. As a consequence, the pressure dependence of the static and electronic dielectric constants i…

EQCM and Quartz Crystal Impedance Measurements for the Characterization of Thiophene-Based Conducting Polymers

1999

AbstractEQCM was extensively used to investigate ion-transport phenomena during dopingundoping processes of electronically conducting polymers. Several early studies assumed that the polymer films were rigidly coupled to the quartz crystal so as to relate the mass change to the quartz crystal resonant frequency change via the Sauerbrey equation. However, the rigidity of electronically conducting polymer films is doubtful and it has to be demonstrated. Quartz crystal impedance analysis near the resonance is of paramount importance to get insight into the viscoelastic properties of the film [1] and to avoid misleading in the interpretation of EQCM data.This contribution presents and discusses…
