Organization of the social sphere and typology of the residential setting: How the adoption of the mobile phone affects sociability in rural and urba…
2012
Abstract The purpose of this study is to explore the role that the possession of the mobile phone plays in the organization of the relational sphere at a social level, in different geographical settings. The research questions were: is the possession of a mobile phone more connected to urban or to rural life, and does the possession of a mobile phone influence differently the organization of the social sphere in rural and urban settings? Data on the possession of mobile phones, the frequency of forms of communicative sociability, and various socio-demographic variables were collected by means of a phone survey in 2009. The sample is representative of the population in the five most populous…
Patterns of variation in tail ornament size in birds
1988
In recent years several different kinds of sexual selection models have been developed, and tail ornaments in birds have frequently been used as an example of a sexually selected character where the models might apply. However, very little is known about intra- and interpopulation variation in ornament size. We have studied the elongated tail ornaments in four species of whydahs Vidua, the forktailed flycatcher Tyrannus savana and the Asian paradise flycatcher Terpsiphone paradisi. Ornaments were relatively longer in males with the longest tarsi (‘heterogony’ with positive allometry). Also, tail lengths were remarkably variable within each geographical area, the coefficient of variation (av…
Perceived value of advanced mobile messaging services: A cross-cultural comparison of Greek and Spanish users
2017
PurposeThe purpose of this paper is to analyse the role of perceived value on post-acceptance behaviour for users of advanced mobile messaging services (AMMS). The paper also compares differences in the influence of perceived value on satisfaction and of satisfaction on loyalty to AMMS in Spain and Greece, to test the moderating effect of culture.Design/methodology/approachPartial least squares path modelling is used to test the model. Perceived value is modelled as a multidimensional reflective construct with four dimensions. Culture is studied at a national level. Differences between countries are tested using the multigroup analysis approach proposed by Henseleret al.(2009).FindingsPerce…
On the sociolinguistic typology of linguistic complexity loss
2012
Published version of an article in the journal: Language Documentation & Conservation. Also available from the publisher at: http://hdl.handle.net/10125/4521 Open access. The nature of the human language faculty is the same the world over, and has been so ever since humans became human. This paper, however, considers the possibility that, because of the influence which social structure can have on language structure, this common faculty may produce structurally different types of language under different sociolinguistic conditions. Changing sociolinguistic conditions in the modern world are likely to have the consequence that, in time, the only languages remaining in the world will be sever…
The dark side of phubbing in the workplace: Investigating the role of intrinsic motivation and the use of enterprise social media (ESM) in a cross-cu…
2022
Despite the increasing phenomena of supervisor phubbing (a counterproductive workplace behaviour of managers), very few studies have explored its outcomes in organisations. This study aims to bridge this gap by investigating the relationships between supervisor phubbing and key employee outcomes. We conducted two studies in cross-cultural settings. In Study 1, which was conducted in Pakistan (a collectivistic culture), we collected 370 useable responses through an online survey from the employees working in the service sector organisations. Study 2, which was conducted in the United States of America (an individualistic culture), utilised the Prolific data collection service to gather 352 r…
Understanding Mobile Showrooming Based on a Technology Acceptance and Use Model
2021
Showrooming is an increasingly popular behaviour in the omnichannel era. The purpose of this paper is to understand the consumer intention to showroom through a technology acceptance and use model based on UTAUT2 that includes value consciousness and purchase involvement as drivers of showrooming intention and mobile dependency as a moderator. Data collected via a survey answered by 659 showroomers were analysed using Partial Least Squares (PLS). Results show that value consciousness, purchase involvement, hedonic motivation and social influence explain mobile showrooming intention and mobile dependency moderates the impact of value consciousness on mobile showrooming intention. Our results…
Intercomparison of instruments for measuring leaf area index over rice
2015
Leaf area index (LAI) is a key biophysical parameter used to determine foliage cover and crop growth in environmental studies in order to assess crop yield. LAI estimates can be classified as direct or indirect methods. Direct methods are destructive, time consuming, and difficult to apply over large fields. Indirect methods are non-destructive and cost-effective due to its portability, accuracy and repeatability. In this study, we compare indirect LAI estimates acquired from two classical instruments such as LAI-2000 and digital cameras for hemispherical photography, with LAI estimates acquired with a smart app (PocketLAI) installed on a mobile smartphone. In this work it is shown that LAI…
A Kalman filter single point positioning for maritime applications using a smartphone
2020
Different positioning techniques have been largely adopted for maritime applications that require high accuracy kinematic positioning. The main objective of the paper is the performance assessment of a Single Point Positioning algorithm (SPP), with a Kalman filter (KF) estimator, adapted for maritime applications. The KF has been chosen as estimation technique due to the ability to consider both the state vector dynamic and the measurements. Particularly, in order to compute an accurate vertical component of the position, suitable for maritime applications, the KF settings have been modified by tuning the covariance matrix of the process noise. The algorithm is developed in Matlab environme…
Effect of specialized applications on the visual functions of amblyopic eye in Latvian children
2021
The classical treatment option of amblyopia is occlusions of non-amblyopic eye. The newest methods involve specialized computer and phone games, applications that involve both eyes in visual processing during treatment as well as stimulate binocularity. The aim of the work was to assess the efficiency of specialized phone application ‘Duovision’ in the treatment of amblyopia in preschool-age children. There were 30 participants (5-8 years old): 16 participants had occlusion therapy; 14 participants played the specialized phone application Duovision®. The visual acuity of amblyopic eye, as well as stereopsis was evaluated at near and far distances before the treatment, 2 and 4 months after t…
Long-term effects of the home literacy environment on reading development: Familial risk for dyslexia as a moderator.
2021
This study aimed to gain better understanding of the associations between literacy activities at home and long-term language and literacy development. We extended the home literacy environment (HLE) model of Sénéchal and LeFevre (Child Development [2002], Vol. 73, pp. 445–460) by including repeated assessments of shared reading, oral language, and reading comprehension development, including examination of familial risk for dyslexia as a moderator, and following development over time from ages 2 to 15 years. Of the 198 Finnish participants, 106 have familial risk for dyslexia due to parental dyslexia. Our path models include development in vocabulary (2–5.5 years), emerging literacy (5.5 ye…
