Background: Implementing evidence-based practices (EBPs) to increase cancer screenings in safety net primary care systems has great potential for reducing cancer disparities. Yet there is a gap in understanding the factors and mechanisms that influence EBP implementation within these high-priority systems. Guided by the Consolidated Framework for Implementation Research (CFIR), our study aims to fill this gap with a multiple case study of health care safety net systems that were funded by an American Cancer Society (ACS) grants program to increase breast and colorectal cancer screening rates. The initiative funded 68 safety net systems to increase cancer screening through implementation of evidence-based provider and client-oriented strategies.Methods: Data are from a mixed-methods evaluation with nine purposively selected safety net systems. Fifty-two interviews were conducted with project leaders, implementers, and ACS staff. Funded safety net systems were categorized into high-, medium-, and low-performing cases based on the level of EBP implementation. Within- and cross-case analyses were performed to identify CFIR constructs that influenced level of EBP implementation.Results: Of 39 CFIR constructs examined, six distinguished levels of implementation. Two constructs were from the intervention characteristics domain: adaptability and trialability. Three were from the inner setting domain: leadership engagement, tension for change, and access to information and knowledge. Engaging formally appointed internal implementation leaders, from the process domain, also distinguished level of implementation. No constructs from the outer setting or individual characteristics domain differentiated systems by level of implementation.Conclusions: Our study identified a number of influential CFIR constructs and illustrated how they impacted EBP implementation across a variety of safety net systems. Findings may inform future dissemination efforts of EBPs for increasing cancer screening in similar settings. Moreover, our analytic approach is similar to previous case studies using CFIR and hence could facilitate comparisons across studies. [ABSTRACT FROM AUTHOR]

Two models are tested on a shake-table. One of the models is a normal reinforced concrete megaframe structure and the other is a multifunctional vibration-absorption reinforced concrete megaframe structure in which the laminated rubber bearings are placed between the major frame and the minor frames. Two earthquake motions (the El Centro wave and the Taft wave) are used during the test. This paper presents the dynamic characteristic, the seismic responses and the failure mechanism of these two models under varying peak acceleration levels for each of the earthquake motions. The test results demonstrate that the aseismic behavior of a multifunctional vibration-absorption reinforced concrete megaframe structure is much better than that of a normal reinforced concrete megaframe structure.

Objective To investigate the factors influencing parenting stress among parents of children with autism spectrum disorder （ASD）， aiming to provide personalized guidance and support for parental care in family interventions. Methods A total of 302 families with young children with ASD who received inpatient interventions at the Child Developmental and Behavioral Center of the Third Affiliated Hospital of Sun Yat-sen University from May 2022 to February 2024 and their parents were recruited to complete the questionnaires， which included Socioeconomic Status Scale （SES）， Parenting Stress Index-Short Form （PSI-SF）， Social Responsiveness Scale-Second Edition （SRS-2） and Adaptive Behavior Assessment System-Second Edition （ABAS-Ⅱ） of the children. Subsequently， relevant data were analyzed. Results There were no statistical differences in parenting stress among parents based on the gender of child， the age of child， parenting style， gender of the primary intervention parent， family annual income， father’s education， and mother’s occupation （all P > 0.05）. However， there were statistical differences in parenting stress among parents in terms of the number of children in the family， mother’s education， and father’s occupation （all P < 0.05）. The scores of PSI-SF were negatively correlated with the comprehensive scores of ABAS-Ⅱ for young children with ASD （P < 0.01）， whereas were positively correlated with the total scores and the score of each dimension of SRS-2 （P < 0.01）. The number of children in the family and ABAS-Ⅱ comprehensive score could not predict parenting stress， while mother’s education， father’s occupation and SRS-2 total score could predict parenting stress， explaining 26.8% of the variance in parenting stress. The effect size of SRS-2 total score was 0.17， contributing the most to regression equation. The main predictor of SRS was the restricted and repetitive behavior dimension （B = 0.709， β = 0.213， P < 0.05）， explaining 21.8% of the variance in parenting stress. Conclusions The more severe the social impairment in the young children with ASD， particularly in terms of restricted interests and repetitive behaviors， the greater the parenting stress. This suggests that in promoting family interventions guided by parents， we should not only focus on alleviating core social communication impairments， but also emphasize parents’ understanding and intervention in children’s restricted interests and repetitive behaviors.

Abstract Direct 3D printing of liquid metal is difficult to form and easy to destroy. In this paper, we developed a 3D printed composite material consisting of a thermoplastic polyurethane (TPU) matrix and liquid metal (LM) dispersed droplets, and introduced the method for realizing 3D printed devices with this composite material: First, the LM is added to 10~50wt %TPU at 190~200 °C through ultrasonic blending to prepare blended ink. After solid cooling, the LM‐TPU composite fiber with a diameter of 600 μm was prepared by Wellzoom desktop extruder at 190 °C at an extrusion speed of 400 mm/min. It has excellent elasticity, with a tensile limit of 0.637 N/m2, and the TPU could evenly wrap LM droplets. Finally, the LM‐TPU fiber is 3D printed at 240 °C by using a 3D printer, and 2D/3D flexible electronic devices with heating and conductive functions could be prepared. The microcircuit has good electrical conductivity; after adding voltage, the circuit has heat release; it could be used as heating equipment to keep warm and used in various flexible wearable electronic products.

Abstract Liquid metals (LM) have shown a very broad development prospect over the past decades. This review article focuses on the latest research dedicated to liquid metal materials and their applications in five significant areas: stretchable conductive composite, intelligent sensing electronic skin, catalysis, 3D printing material, and driving machines. The fabrication, specific properties and application of stretchable liquid metal‐polymer composites that can be used as self‐healing materials have been summarized. Liquid metal deposition printing technology, liquid phase 3D printing, suspension 3D printing technology, micro‐contact printing technology, and in vivo 3D printing molding technology have also been reviewed. Furthermore, the application of liquid metal catalyst in aldehyde reaction, photocatalysis, and electrocatalysis have been discussed. We have shown that electricity, magnetism, sound, light and heat could stimulate the movement of liquid metal. Through this comprehensive overview of the latest research, the main practical application, development, and mechanism of liquid metal were summarized and described. The future development of liquid metal technology was prospected, thus providing a strong basic research support for the further development of LM materials and their applications.
