Predicting fruit and vegetable consumption in long-haul heavy goods vehicle drivers : application of a multi-theory, dual-phase model and the contrib…
2018
Fruit and vegetable intake is insufficient in industrialized nations and long-haul heavy goods vehicle (HGV) drivers are considered a particularly at-risk group. The aim of the current study was to test the effectiveness of a multi-theory, dual-phase model to predict fruit and vegetable consumption in Australian long-haul HGV drivers. A secondary aim was to examine the effect of past fruit and vegetable consumption on model paths. A prospective design with two waves of data collection spaced one week apart was adopted. Long-haul HGV drivers (N = 212) completed an initial survey containing theory-based measures of motivation (autonomous motivation, intention), social cognition (attitudes, su…
On the effects of transmit power control on the energy consumption of WiFi network cards
2009
Transmit power control has been largely proposed as a solution to improve the performance of packet radio systems in terms of increased throughput, spatial reuse and battery lifetime for mobile terminals. However, the benefits of transmit power control schemes on these different performance figures may strongly depend on the employed PHY technology and channel access mechanism. In this paper, we focus on the effects of power control on the energy consumption of WiFi network cards. By means of several experimental tests carried out under different operation conditions and modulation schemes, we try to justify why the reduction of the transmission power has a marginal effect on the overall en…
Energy efficient model for biogas production in farm scale
2011
Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…
Stationary, Second Use Battery Energy Storage Systems and Their Applications: A Research Review
2021
The global demand for electricity is rising due to the increased electrification of multiple sectors of economic activity and an increased focus on sustainable consumption. Simultaneously, the share of cleaner electricity generated by transient, renewable sources such as wind and solar energy is increasing. This has made additional buffer capacities for electrical grids necessary. Battery energy storage systems have been investigated as storage solutions due to their responsiveness, efficiency, and scalability. Storage systems based on the second use of discarded electric vehicle batteries have been identified as cost-efficient and sustainable alternatives to first use battery storage syste…
Football match attendance in Finland
2022
Football fans prefer to see their favourite team win in close matches. Compared to other forms of entertainment, the outcome of sport game is unknown beforehand. Opera audience knows the plot in advance, but in football the winner is revealed only after 90 minutes. The scientific literature of modern sport economics demand theory implies that successful leagues must be based on relatively even competition. This degree of parity within a league is labelled as competitive balance. Sport leagues usually claim that outcome uncertainty is necessary to maintain interest among fans. In this paper, uncertainty of outcome hypothesis is tested applying football data from the highest tier in Finnish m…
Er det forskjell i barns inntak av frukt og grønnsaker og drikke ved 12, 24 eller 48 måneders alder mellom barn av mødre som har deltatt eller ikke d…

Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2019 Background: Women's intake of fruits and vegetables and drinks during pregnancy can affect both mother and child health.Aim: The purpose of this study is to investigate whether the dietary intervention in pregnant women in the Fit for Delivery study has had an effect on what their child is eating and drinking at 12, 24 and 48 months of age.Method: Pregnant women were recruited up to week 20 of pregnancy and were randomized to either a control or intervention group. Participants responded to food frequencyquestionnaires at different time points. Independent sample t-tests were used to analyze the difference in intake of fru…
Land Consumption: A Multidisciplinary Approach to a Cross-Cutting Theme
2016
The idea of the book emerged from one-day conference with the title: The Consumption of Land and Urban Renewal from Agrigento and its Hinterland], held in May 2012 in Agrigento, Sicily, organised by the author. The conference, which saw the participation of interested citizens, has provided the opportunity to inform and raise awareness among the general public about the international issue of land consumption, starting from an analysis of the local situation, marked by its best-known variation: urban sprawl.
Taking a Break from News : A Five-nation Study of News Avoidance in the Digital Era
2021
This article comparatively examines news avoidance in a rapidly changing media environment. We utilize findings from a large dataset of 488 in-depth interviews with media consumers, conducted in Argentina, Finland, Israel, Japan, and the US. We aim to make a contribution to the study of news avoidance by providing a comprehensive and nuanced understanding of the drivers, practices, and patterns of news avoidance as they occur in and are shaped by a variety of national contexts. We argue that news avoidance is shaped not only by individual characteristics, but is also manifested and performed as part of specific time frames and socio-cultural factors. We distinguish two drivers of intentiona…
Trust-oriented affordances: A five-country study of news trustworthiness and its socio-technical articulations
2022
Research on trust has come to the forefront of communication studies. Beyond the dominant focus on informational trust and its country-specific articulations, trustworthiness evaluations can relate to the materiality of news and its global manifestations. Especially in digital algorithmic environments, understanding news trustworthiness requires a holistic approach, which combines informational and socio-technical aspects while addressing both institutional and interpersonal trust. Drawing on 488 in-depth interviews with media consumers in Argentina, Finland, Israel, Japan, and the United States, this article investigates news (dis)trust from the lens of socio-materiality. The six trust-or…
The news consumption of digital natives
2015
Digitalization has shaped the newspaper market and nowadays the news consumption of people increasingly takes place in the online environment. At the same time when print newspapers can no longer be considered as the revenue drivers for media companies, especially digital natives remain reluctant to pay for news content in the digital media. As a result, the digitalization brought by the Internet is challenging the operations of media companies and they need to find new ways to attract consumers to using their services. Digital natives represent a generation that has grown up surrounded by the digital technologies and got used to utilizing the Internet for information collection. So far, th…
