Povzetek: Introduction: Secure attachment develops in early relationships between infants and their caregivers, providing a foundation for emotional security and mental health across the lifespan. In contrast, insecure attachment is associated with maladaptive stress response and an increased risk of both internalizing and externalizing mental health problems. This study examined the association between attachment (in)security and psychopathology in children with type 1 diabetes (T1D) compared with healthy peers. We also considered caregivers’ attachment security and traumatic life events to better understand interacting biopsychosocial factors in children living with a chronic illness.Methods: A group of children with T1D (N = 101) and a group of healthy control children (N = 106) aged 8–15 years and one of their parents were included in the study. A Child Attachment Interview (CAI) was conducted with the children and a Relationship Structures Questionnaire (ECR-RS) with the parents to assess their attachment security. Stressful life events in the children’s lives were recorded using a questionnaire on the traumatic events (LITE). The children’s psychopathology was assessed using the Child Behavior Checklist (CBCL) and the Youth Self-Report (YSR). Descriptive analyses and linear regression models were used to analyze the data.Results: Fifty-nine percent of children had secure attachment, 39% were dismissing, and 2% preoccupied; 16% were classified as disorganized. No significant difference in psychopathology was found between children with T1D and their healthy peers. However, insecure/disorganized attachment was associated with higher psychopathology scores. Simple regression showed positive associations between psychopathology and child attachment insecurity, maternal attachment anxiety, and traumatic life events. A more complex model revealed that male sex, the presence of T1D, maternal attachment anxiety in older children, and the interaction between maternal attachment anxiety and traumatic life events were significantly associated with higher levels of psychopathology.Conclusion: Children with insecure, particularly disorganized, attachment showed higher levels of psychopathology. However, when interaction effects were considered, other factors—such as sex, parental attachment, traumatic life events, and chronic illness—emerged as stronger predictors. These findings highlight the importance of attachment- and trauma-informed care that addresses multiple risk factors to support child and family mental health.

Povzetek: The article investigates the mechanisms through which social forces, networks, cognitive frames, and institutions shape public opinion in Southeast Europe via communication. Employing a qualitative approach, data was collected through synchronous focus groups conducted in six Southeast European countries. The findings reveal that social networks play a pivotal role in shaping public opinion, with organizational position and relationships influencing communication effectiveness. Cognitive frames significantly impact public perception, with entrenched beliefs guiding interpretation of information. Meanwhile, social institutions, such as language and communication rules, influence the clarity and accessibility of messages, thereby shaping public understanding. The research underscores the need for deeper research, ethical standards, and transparent communication to build and maintain public trust. Continuous engagement with the public and adaptability in communication strategies are essential for fostering mutual understanding and trust. This research emphasizes social forces’ complexity and overlapping nature in shaping public opinion and the strategic approaches required for effective communication in Southeast Europe.

Povzetek: Piezoresponse force microscopy (PFM) is a widely used technique for probing the piezoelectric and ferroelectric properties of ceramic materials at the nanoscale. However, its application to ceramic powders remains challenging due to the irregular non-flat shape of the powders. In this study, an approach for PFM analysis of ceramic powders is presented, where ceramic powders are embedded in polymer resin and polished to achieve flat surface for PFM imaging. The approach is demonstrated on ferroelectric PbZr0.53Ti0.47O3 (PZT) and 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 (PMN-35PT) powders. PFM imaging reveals the piezoelectricity within the powder particles and localises the ferroelectric domains within them, while the PFM switching spectroscopy experiment is used to observe the domain switching behavior.
