Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection

2021

At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…

Depressive symptoms and long-term income: The Young Finns Study

2016

Abstract Background Higher depressive symptoms have been associated with lower future income. However, studies examining this issue have had limited follow-up times and have used self-reported measures of income. Also, possible confounders or mediators have not been accounted. Methods 971 women and 738 men were selected from the ongoing prospective Young Finns Study (YFS) that began in 1980. Depressive symptoms were measured in 1992 when participants were from 15 to 30 years old. Information on annual income and earnings from 1993 to 2010 were obtained from the Finnish Longitudinal Employer-Employee Data (FLEED) of Statistics Finland and linked to the YFS. Results Higher depressive symptoms…

Memorable Experiences with Sad Music : Reasons, Reactions and Mechanisms of Three Types of Experiences

2016

Reactions to memorable experiences of sad music were studied by means of a survey administered to a convenience (N = 1577), representative (N = 445), and quota sample (N = 414). The survey explored the reasons, mechanisms, and emotions of such experiences. Memorable experiences linked with sad music typically occurred in relation to extremely familiar music, caused intense and pleasurable experiences, which were accompanied by physiological reactions and positive mood changes in about a third of the participants. A consistent structure of reasons and emotions for these experiences was identified through exploratory and confirmatory factor analyses across the samples. Three types of sadness …

Test-retest reliability of selected items of Health Behaviour in School-aged Children (HBSC) survey questionnaire in Beijing, China

2010

Abstract Background Children's health and health behaviour are essential for their development and it is important to obtain abundant and accurate information to understand young people's health and health behaviour. The Health Behaviour in School-aged Children (HBSC) study is among the first large-scale international surveys on adolescent health through self-report questionnaires. So far, more than 40 countries in Europe and North America have been involved in the HBSC study. The purpose of this study is to assess the test-retest reliability of selected items in the Chinese version of the HBSC survey questionnaire in a sample of adolescents in Beijing, China. Methods A sample of 95 male an…

Employee personal Internet usage in the workplace

2016

Information technology (IT) devices connected to the Internet, such as computers, tablets, and smartphones, have become pervasive in the workplace. These IT devices have greatly facilitated the performance of job tasks for employees. At the same time, employees are increasingly using these technologies for non-work-related purposes during office hours, which is called personal Internet usage in the workplace (PIU). Examples of PIU include, but are not limited to, checking and sending non-work-related emails, surfing news sites, visiting social network sites, e-banking, stock trading, and online shopping, chatting, and gaming. Previous studies on PIU present two schools of thought on PIU out…

Valoración de las necesidades de información de los médicos: publicaciones en el periodo 1990-1998 y estudio de un caso

2000

Los estudios de necesidades de información aportan una metodología con lo cual investigar, de manera sistemática, las características de los usuarios con relación a la información que necesitan para el desarrollo de su trabajo. Igualmente proporcionan criterios objetivos para tomar decisiones a la hora de planificar nuevos sistemas de información o adecuar los ya existentes. Esta tesis ha profundizado en los estudios de necesidades de información en el entorno hospitalario desde dos puntos de vista. Por una parte, se ha establecido un marco teórico de referencia que guíe las investigaciones en este campo. Para ello se ha buscado exhaustivamente la información publicada sobre la materia apor…

Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release

2021

Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…

Relationships Between Health Promoting Activities, Life Satisfaction, and Depressive Symptoms in Unemployed Individuals

2021

Background: Previous research has documented that unemployed individuals who engage in recreational activities, either alone or with others, experience higher levels of mental health and psychological well-being relative to those who do not engage in recreational activities. Aims: In this study, we examined whether engagement in health promoting activities, alone or with other family members, is associated with reduced levels of depression and enhanced levels of life satisfaction in unemployed individuals. Method: We employed a cross-sectional design in which we measured life satisfaction, depressive symptoms, consumption of healthy meals and engagement in physical activities in 203 unemplo…
