Free-living animals often engage in behaviour that involve high rates of workload and result in high daily energy expenditure (DEE), such as reproduction. However, the evidence for elevated DEE accompanying reproduction remain equivocal. In fact, many studies have found no difference in DEE between reproducing vs. non-reproducing females. One of the hypotheses explaining the lack of difference is the concept of energetic ceiling. However, it is unclear whether the lack of increases in energy expenditure is due to the existence of an energetic ceiling and/or compensation by males during parental care. To investigate whether an energetic ceiling exists we experimentally manipulated foraging effort in captive zebra finches, Taeniopygia guttata, creating two groups with high- and low foraging effort followed by both groups breeding in a low foraging effort common garden condition. DEE was measured in both sexes throughout the experiment. Our findings showed sex-specific energy management strategies in response to training for increased foraging effort prior to reproduction. Specifically, males and females responded differently to high foraging effort treatment and subsequently to chick rearing in terms of energy expenditure. Our results also suggested that there appears to be an energetic ceiling in females and that energetic costs incurred prior to reproduction can be carried over into subsequent stages of reproduction in a sex-specific manner.

We explored energy management strategies and developed the Energy Management Scale to facilitate future research and practice in human energy management. Participants were 1,005 employees from multiple organizations and they were divided into 4 samples. The scale reliabilities were acceptable for the physical, emotional, spiritual, and mental energy management dimensions. The initial validity of the scale supported its ability to predict employees' work engagement, recovery, and burnout. Each energy management strategy led to enhanced work engagement. Also, emotional energy management was the most functional in activating recovery processes, and physical energy management was the least functional in reducing work burnout. We have provided a behavioral guide for personnel management and shed light on the implications of energy management for future research.

With the rising load demand and power losses, the equipment in the utility network often operates close to its marginal limits, creating a dire need for the installation of new Distributed Generators (DGs). Their proper placement is one of the prerequisites for fully achieving the benefits; otherwise, this may result in the worsening of their performance. This could even lead to further deterioration if an effective Energy Management System (EMS) is not installed. Firstly, addressing these issues, this research exploits a Genetic Algorithm (GA) for the proper placement of new DGs in a distribution system. This approach is based on the system losses, voltage profiles, and phase angle jump variations. Secondly, the energy management models are designed using a fuzzy inference system. The models are then analyzed under heavy loading and fault conditions. This research is conducted on a six bus radial test system in a simulated environment together with a real-time Power Hardware-In-the-Loop (PHIL) setup. It is concluded that the optimal placement of a 3.33 MVA synchronous DG is near the load center, and the robustness of the proposed EMS is proven by mitigating the distinct contingencies within the approximately 2.5 cycles of the operating period.
