Farmed fish released in a native environment can display different spawning behaviour compared to their wild conspecifics. In our study, farmed and wild burbot, a species recently introduced for aquacultural production, were equipped with electromyogram (EMG) radio tags. EMG biotelemetry allows a description of the spatial distribution of fish together with simultaneous measurements of individual energy consumption. Farmed burbot were released into the wild to simulate stocking or hatchery escape and were observed over a nocturnal phase during November to January. The observational period was assumed to cover the whole spawning season, including an expected peak of spawning activity determined according to egg production by naturally spawning burbot in an experimental seminatural river channel. We detected increased energy consumption and lower movement activity at the time of expected peak spawning for wild burbot only. Across the whole spawning season, farmed females showed lower movement activity and energy consumption than wild females, whereas the opposite results were found for farmed males. Farmed and wild fish kept larger distances between each other than the individuals within a group (farmed and wild) across the whole spawning season. The closest positions occurred between males and females in the wild group, while for farmed fish, the closest position was found within the same sex. Sexually conditioned energy consumption and spatial distribution differed between wild and farmed fish.

This paper presents the results of a game study, comparing Powersaver Game including a competition feature versus the same game excluding a competition feature with respect to energy conservation in the household. In a pretest–posttest design, we tested whether change in attitude, knowledge and behavior with respect to energy conservation in the household was different for participants playing Powersaver Game with or without competition. All energy conservation activities that the application provides (e.g., washing clothes at low temperatures) take place in the real world and feedback is based on real-time energy consumption. This so-called reality-enhanced game approach aims to optimize the transfer between the game world and the real world. Household energy consumption changed significantly and positively in the long term due to competition. A significant difference of 8% in energy consumption between both conditions after the intervention was detected. Besides energy conservation, no further differences were detected between conditions. The chain of events, that an increase in knowledge leads to attitude change, which in turn results in behavior change in the long term is confirmed by means of a path analysis. We conclude that Powersaver Game is effective in the transfer of energy conservation knowledge, which leads to energy saving behavior in the long term while competition additionally contributes to more change in behavior.

And Behavior

The Mexican energy reform of 2013 enabled the development of new management models and energy infrastructure. However, there is growing and unattended evidence of the weight of human behavior analysis in energy consumption. Therefore, this research integrates, with an interdisciplinary approach, the design of a virtual microgrid and an energy market in the Tonalá Campus of the University of Guadalajara, with real-time energy monitoring and behavior change theories. Firstly, the design of a virtual microgrid of 5 buildings, each with a virtual generation plant, is proposed. Each one dimensioned based on its historical demand and the generation of a 499-kWp photovoltaic plant, installed at the Campus. Both consumption and generation have real-time monitoring installed since May 2018. It was from this data that the virtual power plant for each building was dimensioned. Parallelly, the Transtheoretical Model of the stages of change and the Diffusion of Innovation Theory, are applied to design an intervention to modify energy consumption habits in the Campus community and set the foundations of an energy market pilot program.

Although most people understand the threat of climate change, they do little to modify their own energy conservation behavior. One reason for this gap between belief and behavior may be that individual actions seem un-impactful and therefore are not morally relevant. This research investigates how climate change helplessness—belief that one’s actions cannot affect climate change—can undermine the moralization of climate change and personal energy conservation. In Study 1, climate change efficacy predicted both moralization of energy use and energy conservation intentions beyond individual belief in climate change. In Studies 2 and 3, participants read information about climate change that varied in efficacy message, that is, whether individual actions (e.g., using less water, turning down heat) make a difference in the environment. Participants who read that their behavior made no meaningful impact reported weaker moralization and intentions (Study 2), and reported more energy consumption one week later (Study 3). Moreover, effects on intentions and actions were mediated by changes in moralization. We discuss ways to improve climate change messages to foster environmental efficacy and moralization of personal energy use.

In areas such as health, environment, and energy consumption, there is a need to do better. A common goal in society is to get people to behave in ways that are sustainable for the environment or support a healthier lifestyle. Nudging is a term known from economics and political theory, for influencing decisions and behavior using suggestions, positive reinforcement, and other non-coercive means. With the extensive use of digital devices, nudging within a digital environment (known as digital nudging) has great potential. We introduce smart nudging, where the guidance of user behavior is presented through digital nudges tailored to be relevant to the current situation of each individual user. The ethics of smart nudging and the transparency of nudging is also discussed. We see a smart nudge as a recommendation to the user, followed by information that both motivates and helps the user choose the suggested behavior. This paper describes such nudgy recommendations, the design of a smart nudge, and an architecture for a smart nudging system. We compare smart nudging to traditional models for recommender systems, and we describe and discuss tools (or approaches) for nudge design. We discuss the challenges of designing personalized smart nudges that evolve and adapt according to the user’s reactions to the previous nudging and possible behavioral change of the user.

The article presents the results of driving and static tests of pile models with different longitudinal shapes, carried out in laboratory conditions. It was revealed that the specific energy consumption of driving a pyramidal-prismatic pile can either exceed or be less than the specific energy consumption of driving a prismatic pile. Unlike pyramidal piles, pyramidal-prismatic piles have less specific energy consumption for driving. Energy costs for driving pyramidal-prismatic piles, as well as their resistance to pressing vertical loads depend on the length of the pyramidal section and rise with its increase. It has been established that, with the same depth of driving and with the same piles, the specific bearing capacity of the pyramidal-prismatic piles is higher than the prismatic piles and less than the pyramidal pile. The revealed features of the behavior of the pyramidalprismatic piles are due to the influence of the longitudinal shape and the length of the pyramidal part of their shaft on the driving process and behavior under the loads.
