Multiple solutions for a Sturm-Liouville problem with periodic boundary conditions
2013
The main purpose of this paper is to establish the existence of multiple solutions for a Sturm-Liouville problem with periodic boundary conditions. The approach is based on variational methods and multiple critical points theorems
Fractional Hardy inequalities and visibility of the boundary
2013
We prove fractional order Hardy inequalities on open sets under a combined fatness and visibility condition on the boundary. We demonstrate by counterexamples that fatness conditions alone are not sufficient for such Hardy inequalities to hold. In addition, we give a short exposition of various fatness conditions related to our main result, and apply fractional Hardy inequalities in connection to the boundedness of extension operators for fractional Sobolev spaces.
Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction
2020
Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
Communicating across the borders: managing work-life boundaries through communication in various domains
2021
Communicating work issues at home and home issues at work, also known as across-the-border (ATB) communication, is a part of everyday work and family interaction. This study focuses on the concept of ATB communication, using Work/Family Border Theory, according to which the boundaries between work and private life are seen as negotiated and shaped through social interactions and practices. We argue that through ATB communication, and especially by focusing on what is shared and how, employees can manage boundaries and achieve work-life balance. Altogether, 32 informants, comprising journalists (N = 16) and their relational others (N = 16), were interviewed to investigate the role of ATB com…

Work–Family Boundary Management Profiles in Two Finnish Samples : A Person-oriented Approach
2015
Background: The present study aims to identify different work-family boundary management profiles among Finnish employees, and examine how these relate to conflict between work and family or their mutual enrichment. Method: Participants from two samples, one consisting of university staff (n1 = 1,139) and another of nurses (n2 = 271), were asked to respond to an online survey concerning work-family boundary management, work-to-family enrichment, and work-to-family conflict scales. Results: A cluster analysis identified three profiles in both samples: segmentors, integrators and favoring family over work in the university sample, and segmentors, integrators and favoring work over family in t…
