Investigations into the development and role of a Mediterranean intertidal bioconstruction for coastal conservation: the Vermetid Reef
2017
Vermetid reefs are intertidal biogenic habitats created by a dense aggregation of mollusks, frequently cemented by calcareous algae, and are typical of sub-tropical and warm–temperate rocky shores. These bioconstructions are valuable key-habitats of the coastal zones, increasing their productivity and biological value. In the Mediterranean, the main vermetid reef builders belong to the genus Dendropoma and are associated to encrusting coralline red algae. These organisms are ecosystem engineers protected under international European Legislation, although vermetid reef conservation is limited by a lack of biological and ecological knowledge. The two-way interactions between biota and the phy…
Design of mobile phones for older adults : An empirical analysis of design guidelines and checklists for feature phones and smartphones
2017
Design guidelines and checklists are suggested as a useful tool in the development and evaluation of interface design of mobile phones for older adults. Given the intense evolution of mobile phone design, understanding how the design guidelines and checklists have taken into account the advances in mobile phone usability for older adults is important for their correct application and future development. Thus, this study explores the usability dimensions of mobile phone design for older adults and the related changes in terms of time and the type of device (feature phones vs. smartphones) based on an expert coding of the eight mobile phone design guidelines and checklists for older adults pu…
Can we automate expert-based journal rankings? Analysis of the Finnish publication indicator
2020
The publication indicator of the Finnish research funding system is based on a manual ranking of scholarly publication channels. These ranks, which represent the evaluated quality of the channels, are continuously kept up to date and thoroughly reevaluated every four years by groups of nominated scholars belonging to different disciplinary panels. This expert-based decision-making process is informed by available citation-based metrics and other relevant metadata characterizing the publication channels. The purpose of this paper is to introduce various approaches that can explain the basis and evolution of the quality of publication channels, i.e., ranks. This is important for the academic …
Stability of social support during school transitions: Associations with truancy and not completing upper secondary education in normative time
2022
Not completing upper secondary education is often presignaled by truancy from school. Student-perceived social support from family, peers, and teachers can prevent truancy and the risk of not completing education. However, prior studies have not focused on the stability of social support across school transitions. This longitudinal study of 1901 Finnish students examined the extent to which social support was stable or specific to primary, lower secondary, and upper secondary schools. Moreover, we examined whether support was associated with not completing upper secondary education in normative time and whether truancy mediated the relationship between support and not completing education. …
Lapsen vieraannuttaminen toisesta vanhemmasta lapsen huolto- ja tapaamisriidassa : lastensuojelun sosiaalityöntekijöiden näkökulma
2014
Pro Gradu -tutkielmassani olen selvittänyt, minkälaisia kokemuksia lastensuojelun sosiaalityöntekijöillä on lapsen vieraannuttamisen tilanteista lapsen huolto- ja tapaamisriidan yhteydessä. Olen selvittänyt minkälaisena lastensuojelullisena ilmiönä vieraannuttaminen koetaan, mitä haasteita lastensuojelun sosiaalityöntekijät kohtaavat ja minkälaisia interventiomahdollisuuksia lastensuojelun sosiaalityöntekijöillä on lapsen vieraannuttamisen tilanteissa. Lapsen vieraannuttaminen ilmiönä paikantuu kuntien perheoikeudellisten sopimuspalveluiden ja lastensuojelun sosiaalityön rajapinnalle. Määrittelen lapsen vieraannuttamisen vanhemman käyttäytymiseksi erotilanteessa siten, että lapsen ja toisen…
Organisational Legitimation Strategies in Social Media : How Business Schools Address Declining Ranking
2023
Public relations scholarship has drawn on organisational legitimacy theory to show how organisations appeal to stakeholders’ acceptance of their existence and importance in society. Studies have shown how different types of organisations utilise communication strategies in social media to gain legitimacy. This chapter contributes to public relations research by examining how a sample of business schools implemented legitimation strategies in their social media posts when their legitimacy was threatened. The findings show that when ten world-class European business schools faced declining institutional rankings between 2016 and 2019, they made use of four legitimation strategies—authorisatio…
