Low Temperature Drying With Air Dehumidified by Zeolite for Food Products: Energy Efficiency Aspect Analysis

Developments in low temperature drying of food products are still an interesting issue; especially with respect to the energy efficiency. This research studies the energy efficiency that can be achieved by a dryer using air which is dehumidified by zeolite. Experimental results are fitted to a dynamic model to find important variables for the drying operation. The results show that ambient air temperature as well as the ratio between air flow for drying and air flow for regeneration, affect the energy efficiency significantly. Relative humidity of used air, and shift time have a minor effect on the dryer performance. From the total work, it can be noted that the dryer efficiency operated at 50-60°C achieves 75 percent, which is attractive for drying of food products

Exploring the Implementation of Lesson-Level UDL Principles Through an Observation Protocol

The researchers piloted an observational protocol to examine the Universal Design for Learning (UDL) principles and checkpoint strategies used during daily instruction with a small sample of general and special education teachers. Observational research on UDL has been recommended within the literature. Researchers used the high-leverage practice of explicit instruction as the anchor for the design of the observation protocol. Findings indicate there is alignment between observed UDL principles and strategies employed at the lesson level and teachers’ self-reports of the UDL principles and strategies employed. Findings also suggest that teachers are using several UDL principles within their daily instruction and that there is overlap among UDL checkpoint strategies and aligned UDL principles. Essential UDL principles that pre-service and in-service teachers are expected to deliver at the lesson level can be prioritised to ensure a developmental approach to the implementation of UDL. Implications and recommendations for future research are discussed

Does sports participation affect the mediating role of impulsivity in the association between adverse childhood experiences and aggression?

IntroductionAdverse childhood experiences (ACEs) and self-reported aggression have often been associated, however, the mediating and moderating mechanisms underlying this association are not fully understood. In addition, less is known about potential factors that could serve as protection against the development of aggressive behavior. In this study, we investigated a moderated mediation model of sports participation and five impulsivity traits including positive and negative urgency, sensation seeking, and lack of premeditation and perseverance, in the association between ACEs and two forms of aggression.Methods and resultsThe sample comprised 651 (68.5% females) individuals from a Dutch community ranging in age from 18 to 82 years (M = 34.08). Contrary to our expectations, sports participation did not affect the associations of ACEs, the five impulsivity traits, and reactive and proactive aggression, except the association between ACEs and lack of premeditation. Specifically, the detrimental effect of ACEs on the propensity to act without thinking, increases among individuals with lower levels of sports participation. In addition, it was also found that sports participation directly contributed to higher levels of sensation seeking. Finally, after controlling for sociodemographic variables, the positive association between ACEs and reactive aggression was significantly mediated by negative urgency, lack of perseverance, and lack of premeditation, while the positive association between ACEs and proactive aggression was significantly mediated by lack of premeditation and positive urgency.ConclusionThe findings of this study add to the body of knowledge about the role of sports participation and impulsivity traits in the development of both forms of aggression, however, replication studies among multiple populations are needed before firm conclusions can be drawn

Post-observation conversations in the museum: using the self-evaluation of the supervisee as the starting point

Post-observation conversations are often used to discuss the quality of teaching and education; however, little is known about the use of this method for the evaluation of teaching in museums. Drawing on interviews, in the first research question, we explored how museum guides (n = 14) and educators (n = 8) perceived a post-observation conversation when they used the guide's self-evaluation as the starting point. This is in contrast to the educator (observation) directed conversations that currently prevail in the participating museums, all located in the Netherlands. For the second research question, we coded seven conversations in order to investigate the guides’ and educators’ actual participation. Results indicate that guides felt a sense of ownership; furthermore, the participants evaluated the conversations as more equally balanced. Analysis of the conversations confirmed that there was a balanced interaction and that the guides greatly influenced the conversation's content

Subnormal short‐latency facial mimicry responses to dynamic emotional facial expressions in male adolescents with disruptive behavior disorders and callous‐unemotional traits

Using still pictures of emotional facial expressions as experimental stimuli, reduced amygdala responses or impaired recognition of basic emotions were repeatedly found in people with psychopathic traits. The amygdala also plays an important role in short‐latency facial mimicry responses. Since dynamic emotional facial expressions may have higher ecological validity than still pictures, we compared short‐latency facial mimicry responses to dynamic and static emotional expressions between adolescents with psychopathic traits and normal controls. Facial EMG responses to videos or still pictures of emotional expressions (happiness, anger, sadness, fear) were measured. Responses to 500‐ms dynamic expressions in videos, as well as the subsequent 1500‐ms phase of maximal (i.e., static) expression, were compared between male adolescents with disruptive behavior disorders and high (n = 14) or low (n = 17) callous‐unemotional (CU) traits, and normal control subjects (n = 32). Responses to still pictures were also compared between groups. EMG responses to dynamic expressions were generally significantly smaller in the high‐CU group than in the other two groups, which generally did not differ. These group differences gradually emerged during the 500‐ms stimulus presentation period but in general they were already seen a few hundred milliseconds after stimulus onset. Group differences were absent during the 1500‐ms phase of maximal expression and during exposure to still pictures. Subnormal short‐latency mimicry responses to dynamic emotional facial expressions in the high‐CU group might have negative consequences for understanding emotional facial expressions of others during daily life when human facial interactions are primarily dynamic
