Prescription opioid use and employment : A nationwide Finnish register study

2021

Background: The secular decline in labor market participation and the concurrent increase in opioid use in many developed countries have sparked a policy debate on the possible connection between these two trends. We examined whether the use of prescription opioids was connected to labor market outcomes relating to participation, employment and unemployment among the Finnish population. Methods: The working-age population (aged 19–64 years) living in Finland during the period 1995–2016 was used in the analyses (consisting of 67 903 701 person-year observations). Lagged values of prescription opioid use per capita were used as the exposure. Instrumental variables (IV) estimation method was u…

Examining Consumers’ Usage Intention of Contactless Payment Systems

2019

Purpose The purpose of this paper is to develop and test a conceptual model that combines the modified Unified Theory of Acceptance and Use of Technology (UTAUT2) with a consumer brand engagement (CBE) model to predict consumers’ usage intentions toward contactless payment systems in a developed country. Design/methodology/approach The authors cooperated with a contactless payment service provider in Finland and reached out to 22,000 customers, resulting in 1,165 usable responses. The collected data were analyzed using structural equation modeling. Findings The study shows that the UTAUT2 and the CBE model together explain approximately 70 percent of the variance in usage intention. Of the…

Ichthyocotylurus pileatus -imumatoloisen esiintyminen ja elämänkiertopiirteet Valvata macrostoma -kotiloissa

2011

Ichthyocotylurus pileatus on ahvenkaloissa yleinen imumatoloinen, jonka elämänkiertoon kuuluu 3 isäntää. Pääisäntä on kalaa ravinnokseen käyttävä lintu, 1. väli-isäntä on liejukotiloihin kuuluva Valvata macrostoma –kotilo, jonka kautta loinen parveilee veteen ja tunkeutuu 2. väli-isäntäänsä kalaan (Perca fluviatilis). Loisen yleisyydestä huolimatta sen elämänkiertopiirteitä ei tunneta kovin hyvin. Työni päätavoite oli selvittää mitkä tekijät vaikuttavat siihen, että Ichthyocotylurus -imumatoloisten esiintyminen on niin yleistä ja runsasta makeanveden kaloissa, vaikka loisten siirtyminen isännästä toiseen on yleisesti ottaen epätodennäköistä. Näitä tekijöitä selvitin tutkimalla Valvata macro…

El uso del vídeo en la docencia desde la mirada del profesorado

2021

El vídeo es uno de los recursos didácticos más utilizados en la enseñanza. En esta investigación cualitativa se analizan las respuestas del profesorado de Educación Secundaria y Educación Superior (n=60), durante el curso 2020-21, a un cuestionario sobre la transformación digital de la docencia a causa del Covid-19, con el objetivo de conocer qué tipo de uso del vídeo se realiza y con qué criterios se integra. Los resultados muestran que predomina su utilización como transmisor de información e instrumento motivador y de conocimiento (Ballesteros-Regaña, 2013; Cebrián, 2005; Salinas, 1992) y que los principales criterios de integración del vídeo (Ballesteros-Regaña, 2013) son el destinatari…

Associations of Environmental Features With Outdoor Physical Activity on Weekdays and Weekend Days: A Cross-Sectional Study Among Older People

2020

Background: Physical activity (PA) of higher intensity and longer duration mainly accumulates from older adults' out-of-home activities. Outdoor PA is influenced by environmental features; however, the day-to-day variability of PA and its associations with environmental features have not been widely studied. This study focused on the associations of environmental features with accelerometer-measured PA in older people on weekdays and weekend days.Methods: The study population comprised 167 community-dwelling older people aged 75–90 years. Accelerometers were worn on 7 consecutive days and a structured interview on physical functioning, health, and socioeconomic factors was administered. A g…

Multimodal Aposematic Signals and Their Emerging Role in Mate Attraction

2018

Chemically defended animals often display conspicuous color patterns that predators learn to associate with their unprofitability and subsequently avoid. Such animals (i.e., aposematic), deter predators by stimulating their visual and chemical sensory channels. Hence, aposematism is considered to be “multimodal.” The evolution of warning signals (and to a lesser degree their accompanying chemical defenses) is fundamentally linked to natural selection by predators. Lately, however, increasing evidence also points to a role of sexual selection shaping warning signal evolution. One of the species in which this has been shown is the wood tiger moth, Arctia plantaginis, which we here put forward…

WASTE PLASTICS MANAGEMENT IN MUNICIPALITIES: LOGISTICS AND PROCESSES IN LOMBARDIA (NORTHERN ITALY)

2013

A partnership of 49 Municipalities lying in Lombardia (Northern Italy) and belonging to the District “Monza and Brianza” has entrusted the management of the Municipal Solid Waste (MSW) to two Public Companies: “C.E.M. Ambiente S.p.A.” - which owns and operates a transfer station and a multi-material centre - and “SERUSO S.p.A.”, whose single facility is set up and equipped for a high performance factory sorting of the dry fraction of the urban waste. The catchment area is populated by 448 000, living in an area of 366 km2. The management system starts with household sorting for multi-bin curbside collection; followed by hauling to selection and physical treatment facilities; and last, trans…

Towards a new protocol for field measurements of greenhouse gases from wastewater treatment plant

2016

Emissions into the atmosphere of greenhouse gases (GHGs), i.e., carbon dioxide, methane and nitrous oxide from wastewater treatment plants are of increasing concern in the water industry. In order to produce useful and comparable information for monitoring, assessing and reporting GHG emissions from wastewater treatment plants, there is a crescent need for a general accepted methodology. This paper aims at proposing the first protocol for monitoring and accounting GHG emissions from wastewater treatment plants taking into account both direct and internal indirect emissions focusing on sections known to be major responsible of GHG emissions i.e. oxidation tanks and sludge digestion. The main…

Biopolymer Recovery from Aerobic Granular Sludge and Conventional Flocculent Sludge in Treating Industrial Wastewater: Preliminary Analysis of Differ…

2022

The recovery of biopolymers from sewage sludge could be a crucial step in implementing circular economy principles in wastewater treatment plants (WWTP). In this frame, the present study was aimed at evaluating the simultaneous production of polyhydroxyalkanoates (PHA) and extracellular polymeric substances (EPS) obtainable from the treatment of agro-industrial wastewater. Two biological enrichment systems, aerobic granular sludge (AGS) and a conventional activated sludge operating as a sequencing batch reactor (SBR), were monitored for 204 and 186 days, respectively. The maximum biopolymers accumulation capacity was close to 0.60 mgPHA-EPS gVSS−1 in the AGS when operating at 3 kgCODm…
