Abstract: In this letter we present a method for calculation of linear heat flow in inhomogeneous solids. The method is based on the evaluation of transfer matrices for each layer in a multilayered structure from the Laplace transformation of the partial differential equation of heat conduction. The multilayered structure is then described by a matrix obtained as a chain of products of in idual layer transfer matrices and corresponding boundary thermal resistivity matrices. The analytic expression for the nth power of the multilayered transfer matrix is found, describing a periodic multilayered structure composed of n equal multilayered structures. The application of the presented method for calculation of photothermal signals is also shown. Dispersion relation for the thermal waves in inhomogeneous solids is obtained from the matrix elements of the transfer matrix. Finally, from the dispersion relation explicit expressions for the effective values of thermal diffusivity and conductivity of both the discontinuously and continuously inhomogeneous solids are evaluated.

Abstract: Increasingly, health services are adopting short‐term consultative therapy models, such as single session therapy, to cope with increased service demands, finite budgets and changing consumer expectations. Within the paediatric sub‐specialty of child development and behaviour, allied health clinicians are central to supporting families to understand their children, provide therapeutic interventions and help achieve optimal developmental and health outcomes. This study aimed to describe parents'/caregivers' engagement during advanced allied health consultations utilizing a single session therapy framework for managing neurodevelopmental and behavioural concerns in children. Between March to June 2021, 14 parents participated in a qualitative study involving focus groups. Reflexive thematic analysis was used to code and interpret the data to understand and explore families' engagement in single session therapy. Three overarching themes relating to parents' engagement during consultations emerged from the data: connection with the clinician, parental attributes and organizational influences. Clinician connection was the prominent construct that enhanced parent attributes and the positive perception of the organization in an ongoing manner. There was a complex interplay between the behavioural and affective components of the clinician, parents and the organization to create mutual presence, valued time, understanding and action. This study demonstrates the importance of clinician connection, parental attributes and organizational influences to enhance engagement in therapeutic consultations. These factors are interrelated and are a complex blend of behaviour and internal states and highly in idualized for each family. Understanding how services can continue to engage families is integral to ongoing sustainability and overall health and well‐being.

Abstract: Single session therapy (SST) has emerging evidence for facilitating meaningful therapeutic change in a small number of consults, rather than more traditional long‐term therapies. This study aimed to explore and describe the parent/caregiver and child experience with advanced allied health practitioners (AAHP) using SST for children with developmental disabilities, by understanding key characteristics of the consultation that led to therapeutic change. Eligible families attending an AAHP outpatient clinic for children with developmental and behavioural concerns participated in one to four SST consultations around their identified areas of need. Semi‐structured interviews were conducted with 38 parents and 12 children, from 37 different families. Thematic analysis was used to analyse interviews. Demographic information was gathered through parent interviews and by reviewing hospital records. Four key themes emerged relating to the characteristics of the consultation that led to a positive experience for families: (1) the art of mutual presence (2) the value of time (3) the power of understanding and (4) the trust of action. These attributes were influenced by the overarching complexities of the AAHP, the parent's and child's interpersonal skills, and the organisational mechanisms influencing patient care. Parents and children reported clinical change during the consult through increased understanding, and being heard, valued, and respected for their in idual decisions on how to manage their child's and family's needs. This study provides preliminary evidence that utilising SST for children and families with developmental and behavioural needs facilitates a positive experience valued by families. SST, with a focus on a family's in idual identified areas of concern, was valued and effective when delivered by AAHP. This suggests that SST, when appropriately administered by experienced and trained health practitioners, is useful for families dealing with children with developmental and behavioural challenges.
