    Le vandalisme dans l’information géographique volontaire

    Du concept à la détection non supervisée d’anomalie

    Quy Thy Truong1 , Guillaume Touya2, Cyril de Runz3

    Revue Internationale de Géomatique, Vol.29, No.1, pp. 31-56, 2019, DOI:10.3166/rig.2019.00073

    Abstract Since vandalism is a serious matter for the quality of Volunteered Geographic Information, this paper aims at exploring machine learning techniques that enable its detection. First, a focus on the various definitions of vandalism highlights the complexity of this concept. This focus comprises a case study on proven vandals in OpenStreetMap (OSM). Second, we present an experimental vandalism detection on OSM data using a clustering-based outlier detection. The analysis of initial results leads to a discussion about the construction of an OSM vandalism corpus that would be useful in a supervised learning context.

    Volunteering and Depression among Older Adults: An Empirical Analysis Based on CLASS 2018

    Zhendong Wu1, Chen Xu2, Liyan Zhang3, Yang Wang4, George W. Leeson5, Gong Chen4,*, Julien S. Baker6, Xiao-Guang Yue7,8

    International Journal of Mental Health Promotion, Vol.25, No.3, pp. 403-419, 2023, DOI:10.32604/ijmhp.2023.024638

    Abstract Introduction:: Older adults are prone to high levels of depression due to their deteriorating physical functions and shrinking social networks after retirement. Volunteering as an important social activity is essential for alleviating depression by building social network. This paper aims to examine the effect of volunteering on depression among older adults by using China Longitudinal Aging Social Survey (CLASS 2018) data.Methods:: This study uses descriptive analysis and chi-square tests to show differences in demographic factors of older adults’ volunteerism participation, followed by bivariate correlation analysis to examine the correlation between the vital variables. Afterward, stratified linear regression analysis is used… More >

    Why Insisting in Being Volunteers? A Practical Case Study Exploring from Both Rational and Emotional Perspectives

    Kuei-Feng Chang1, Wen-Goang Yang2, Ya-Wen Cheng3, I-Tung Shih2,*

    International Journal of Mental Health Promotion, Vol.24, No.2, pp. 219-236, 2022, DOI:10.32604/ijmhp.2022.018187

    Abstract This study explored the mechanism on how volunteers as rationalists use rationalism during their cognitive appraisal process when dealing with emotional events in their social helping behavior such as international rescue events. The authors used the triangulation method to include three studies (Study 1 is a qualitative research which explored ways of TCF leader’s inspiring their volunteer workers; Study 2 is a quantitative research on the decision-making process of volunteer individuals involving in international rescue activities; Study 3 is a quantitative research on individuals’ motivation for joining social helping behavior) for validation of Tzu Chi Foundation (TCF), which is a… More >

    IoT-EMS: An Internet of Things Based Environment Monitoring System in Volunteer Computing Environment

    Sourav Kumar Bhoi1, Sanjaya Kumar Panda2, Kalyan Kumar Jena1, Kshira Sagar Sahoo3, N. Z. Jhanjhi4,*, Mehedi Masud5, Sultan Aljahdali5

    Intelligent Automation & Soft Computing, Vol.32, No.3, pp. 1493-1507, 2022, DOI:10.32604/iasc.2022.022833

    Abstract Environment monitoring is an important area apart from environmental safety and pollution control. Such monitoring performed by the physical models of the atmosphere is unstable and inaccurate. Machine Learning (ML) techniques on the other hand are more robust in capturing the dynamics in the environment. In this paper, a novel approach is proposed to build a cost-effective standardized environment monitoring system (IoT-EMS) in volunteer computing environment. In volunteer computing, the volunteers (people) share their resources for distributed computing to perform a task (environment monitoring). The system is based on the Internet of Things and is controlled and accessed remotely through… More >

    Formal Volunteering and Mental Health in South Korea: Does Age Matter?

    Manacy Pai1, Joongbaeck Kim2,*

    International Journal of Mental Health Promotion, Vol.23, No.1, pp. 27-42, 2021, DOI:10.32604/IJMHP.2021.011996

    Abstract Extensive research shows a positive association between formal volunteering and mental health and this association is stronger for older adults compared to their younger peers. The purpose of our study is to re-examine the link between formal volunteering, age, and mental health in a non-western society, South Korea. We employ two recent waves—years 2012-13 -- of nationally representative data from the Korea Welfare Panel Survey to test the extent to which the relationship between formal volunteering and mental health, as measured by depression, varies across two non-elderly age groups—young adults (18–35) and those middle-aged (36–55). Findings reveal that being a… More >

    Challenges and Growth as a Mental Health Professional from Volunteering Experiences in the Community Gambling Awareness Campaign

    So Yeon Yoo1, Yun-Jung Choi2,*, Youn-Joo Um2,*

    International Journal of Mental Health Promotion, Vol.22, No.2, pp. 83-91, 2020, DOI:10.32604/IJMHP.2020.011299

    Abstract As the demand for high-quality mental health services increases, producing expert nurses with the skills and expertise to deal with various complex mental health situations involving diverse subjects is critical. Nursing programs should be prepared to provide education that can improve mental health professional competence. Using a qualitative study and focus group interviews, we focused on the experiences of nursing students who voluntarily participated in campaign activities to prevent gambling problems. The respondents were 23 nursing students who participated in the campaign for more than four months. Data were analyzed using Downe-Wamboldt’s eight steps of content analysis. The experiences of… More >
