Decolorization Kinetics of Sludge Protein Solution by ~（60）Coγ-Ray Irradiation/H_2O_2 Oxidation

In order to carry out decolorization, sludge protein solution, a dark brown close to black solution from activated sludge, was subjected to ⁶⁰Co γ-ray irradiation in the presence of hydrogen peroxide. UV/Vis spectrophotometric method was used to investigate the effect of H2O2 on the coloration apparent kinetics and rate constants of sludge protein solution under γ-ray irradiation. In addition, the effects of irradiation dose, initial sludge protein solution concentration, and pH value on the decolorization efficiency of sludge protein solution were studied. Results showed that the decolorization apparent kinetics of sludge protein solution was a first-order reaction. The solution decolorization percentage increased with the increase of irradiation dose or the decrease of initial sludge protein solution concentration. The examination results of pH value showed that the sludge protein solution could be more efficiently decolorized in alkaline media than in acid media. Moreover, sensory evaluation and foamability analysis indicated that irradiated samples under H2O2 oxidation showed better sensory score and foamability.

Effects of audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity

The present experiment sought to further understanding of the effects of personalised audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity. Twenty-four participants (M_age = 28.3, SD = 5.5 years; M_BMI = 32.2, SD = 2.4) engaged in self-paced exercises on a recumbent cycle ergometer and three conditions (sensory stimulation [ST], sensory deprivation [DE], and control [CO]) were administered. Perceptual (attentional focus and perceived exertion), affective (affective state and perceived activation), and psychophysiological (heart rate variability) parameters were monitored throughout the exercise bouts. A one-way repeated measures analysis of variance was used to compare self-reported and psychophysiological variables (main and interaction effects [5 Timepoints × 3 Conditions]). The results indicate that ST increased the use of dissociative thoughts throughout the exercise session (η_p² = .19), ameliorated fatigue-related symptoms (η_p² = .15) and elicited more positive affective responses (η_p² = .12) than CO and DE. Accordingly, personally-compiled videos are highly effective in ameliorating exertional responses and enhancing affective valence during self-paced exercise in adults with obesity. Audiovisual stimuli could be used during the most critical periods of the exercise regimen (e.g., first training sessions) when individuals with obesity are more likely to focus on fatigue-related sensations.

Supporting emotion regulation in individuals with ASD,ADHD and bipolar disorder through trauma-informed instruction and self-regulation strategies

Since the beginning of the COVID-19 pandemic, students have endured drastic changes in educational routines. Such disruptions can be especially challenging for students who struggle with executive functioning, self-regulation and emotion regulation, such as students with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and bipolar disorder. Using a framework of trauma-informed instruction, the authors supported classroom teachers in implementing sensory spaces for students with ASD, ADHD and bipolar disorder. The project included professional development and funding for teachers to develop, procure and offer sensory tools and strategies to assist students in recognising and managing emotions. The authors collected data on the effectiveness of the sensory supports, combining teacher surveys and student behaviour data. Results indicated increased teacher knowledge on trauma-informed instruction and use of sensory supports to promote executive functioning and self-regulation and decreased target behaviours in students based on structured observation and anecdotal teacher feedback.     

The nexus between innovativeness and knowledge management: A focus on firm performance in the hospitality sector

While the importance of knowledge management is increasingly acknowledged, many firms do not fully understand the significance of innovativeness in relation to knowledge management and firm performance. Consequently, the objective of this article is to investigate innovativeness and its relationship with knowledge management and organizational performance in an under-examined industry sector and country context. The study methodology was survey-based and took place in the hospitality industry sector in Lesotho, Africa. Findings highlight the importance of knowledge management practices as an important driver of firm performance, where the results emphasize the positive mediating effect of innovativeness on the relationship between knowledge management and firm performance. The study has important practitioner and policy implications, where it is recommended that knowledge management be utilized in conjunction with innovativeness so as to positively influence firm performance. The article delivers a novel contribution to the literature in terms of establishing empirical associations between knowledge management, innovativeness and firm performance in an emerging country context.
