The blow-up rate for a loglog non-scaling invariant semilinear wave equation
No full text28 pagesInternational audienceWe consider blow-up solutions of a semilinear wave equation with a loglog perturbation of the power nonlinearity in the subconformal case, and show that the blow-up rate is given by the solution of the associated ODE which has the same blow-up time. In fact, our result shows an upper bound and a lower bound of the blow-up rate, both proportional to the blow-up solution of the associated ODE. The main difficulty comes from the fact that the PDE is not scaling invariant
Self-Discrepancies and Eating Disorder Symptoms: Investigating the Role of Approach-Avoidance Temperaments
Full text linkSelf-discrepancies refer to perceived gaps between one’s actual self (characteristics one believes they currently possess), ideal self (attributes one aspires to have), and ought self (attributes one feels obligated to possess). Large actual-ideal and actual-ought self-discrepancies have been consistently associated with increased eating pathology. However, the potential role of the feared self—representing undesired personal characteristics — and the link between actual-feared self-discrepancies and eating pathology remains underexplored. Further, recent evidence suggests that approach and avoidance motivational orientations (e.g., reflecting sensitivity to reward and punishment) independently contribute to eating disorder (ED) symptoms and, importantly, may also interact with self-discrepancies to exacerbate ED symptom severity. As such, the present study examined the relationship between actual-ideal and actual-feared self-discrepancies and ED symptoms while also investigating approach and avoidance temperaments as potential moderators. Undergraduate participants (N = 89) completed an online questionnaire battery assessing these constructs. As hypothesized, actual-feared self-discrepancy was significantly associated with both avoidance temperament and ED symptoms. In contrast to previous research, neither actual-ideal self-discrepancy nor approach temperament was significantly associated with ED symptoms. Moderation analyses were non-significant. Taken together, preliminary findings suggest that actual-feared self-discrepancies may be relevant to eating pathology, warranting further investigation into causal pathways and intervention strategies
When Smartphones Come Between Us: The Development and Preliminary Validation of the Perceived Neglect Due to Partner Phubbing Scale (PNPS)
Full text linkAs smartphone use becomes increasingly pervasive, the phenomenon of partner phubbing (Pphubbing) – diverting attention to a smartphone while in the presence of a romantic partner – has received growing empirical attention. This study addresses gaps in the literature by introducing the Perceived Neglect due to Partner Phubbing Scale (PNPS), the first psychological measure specifically designed to assess feelings of neglect stemming from Pphubbing in romantic relationships. A sample of 102 Canadian adults who reported being in a romantic relationship completed the Partner Phubbing Scale (a behavioural measure), the newly developed PNPS, a relationship satisfaction measure, and demographic items. Reliability analyses, inter-item correlations, and principal components analysis were conducted to reduce the number of items on the PNPS, resulting in a two-component structure with reliable subscales. In accordance with the hypothesized relationships, PNPS scores were positively associated with the behaviour of Pphubbing and negatively associated with relationship satisfaction. These findings provide preliminary support for the PNPS’ construct validity. Supporting an exploratory hypothesis, results indicated that women reported significantly greater perceived neglect than men. These findings align with prior literature, suggesting that women experience stronger emotional reactions to Pphubbing. Limitations and future directions associated with the current study are outlined. Future research should utilize the PNPS to examine additional correlational relationships with variables such as attachment styles, communication patterns, and personality traits. Moreover, incorporating diverse methodologies, such as diary-based designs, may offer nuanced understanding of how individuals in romantic relationships experience perceived neglect due to Pphubbing over time

The Conversational Functions and Effects of Tagalog-English Code-Switching on Filipino Television
Full text linkTaglish is the code-switching or alteration between Tagalog and English within a single utterance. The prevalence of Tagalog-English code-switching in the Philippines results from the widespread use of both languages in Philippine educational institutions. This paper qualitatively analyzes the use of Taglish in spontaneous conversations and interviews in the Philippine magazine show Kapuso Mo, Jessica Soho (Your Heartmate, Jessica Soho) to identify the communicative effects of Tagalog-English code-switching in Filipino discourse. The results suggest the prevalence of code-switching as all 17 identified speakers in the study used both Tagalog and English in their speeches at varying degrees. Results also revealed the following communicative effects of code-switching: efficiency, message qualification, linguistic play, emphasis, objectivization, and personalization. Furthermore, code-switching facilitated the speakers’ identity construction, by representing factors such as wealth, success, authority, knowledge, and solidarity.

Morin is a proud Métis multimedia artist from North Battleford, SK, currently at the University of Saskatchewan pursuing a degree in Archaeology/Anthropology with a minor in Studio Art. Her work is inspired by bright, bold colours and learning about their Métis heritage. Her work spans whimsical depictions of the human form, ethereal beings, and, more recently, learning about her Métis heritage in a different light. By blending vibrant colours with delicate linework, they embrace a playful yet introspective style, influenced by her bubbly personality and a keen eye for the abstract.

Effect of Post-Exercise Dry Cupping Therapy on Muscle Recovery
Full text linkCollege of Kinesiology Research Theme: Human Performance
Introduction: Dry cupping therapy has gained popularity in athletic settings as a recovery modality, yet empirical evidence supporting its effectiveness remains limited. The practice involves using suction to create negative pressure on the skin, which is theorized to promote blood flow and tissue recovery.
Purpose: To determine whether post-exercise dry cupping therapy would improve recovery of muscle strength, reduce muscle soreness, and limit swelling compared to a sham control arm.
Methods: Ten resistance-trained adults (aged 20-22) participated in a randomized, within-subject, blinded trial. Participants performed a biceps-focused muscle-damaging exercise. One arm received dry cupping therapy post-exercise, while the opposite arm received a sham cupping treatment (cups applied with no suction). Assessments were conducted at six time points: pre-exercise, post-exercise, post-cupping, and 24, 48, and 72 hours post-exercise. Outcomes included muscle strength (isometric torque via Biodex), muscle thickness (ultrasound), and soreness (Visual Analog Scale). Differences were analyzed using repeated-measures ANOVA to assess arm × time interactions and time main effects.
Results: There were no significant arm × time interactions for any outcome, indicating similar recovery patterns between cupped and control arms. Significant time main effects were observed for all outcomes (p < 0.01). Muscle strength decreased post-exercise and remained below baseline at 24, 48, and 72 hours (p < 0.05). Muscle thickness increased post-exercise and remained elevated at 24 and 48 hours before returning to baseline by 72 hours (p < 0.05). Muscle soreness increased post-exercise and remained elevated at all follow-up time points (p < 0.05).
Conclusion: Dry cupping therapy applied after resistance exercise did not significantly improve recovery of strength, soreness, or swelling compared to the control, who received sham treatment. These findings suggest that cupping may not provide additional recovery benefits beyond placebo
