Housing and child development: key dimensions, knowledge gaps and issues for future research in Australia

This paper begins by reviewing the existing international literature on the links between housing and child development. The housing environment can significantly improve or hinder a child’s physical, social, emotional, behavioural and cognitive development directly and via its impacts on the child’s parenting methods. The review of international literature is drawn from a range of disciplines including sociology, epidemiology, economics, housing policy, social welfare, health, medicine, child development and psychology. It highlights key dimensions of children’s housing circumstances that are associated with their health and development. These include housing tenure, neighbourhood conditions, housing affordability, homelessness, frequency of residential moves, extent of crowding, housing disrepair, environmental allergens and toxicants used in the home. The paper also raises some important conceptual and methodological issues that need to be addressed in examining the causal pathways through which housing factors influence child developmental outcomes. In particular, there is a need to isolate housing factors from confounding influences such as parental socio-economic status and identify mediating factors such as parenting behaviour, and the inter-relationships between different housing factors that need to be accounted for.There is currently a dearth of empirical studies that analyse the links between housing and child development in Australia, despite the plethora of studies examining these links in other developed countries such as the United States and United Kingdom. Hence, the third part of this paper utilises officially published statistics and the limited pool of Australian studies to highlight key policy issues requiring urgent empirical research in Australia in the near future. These issues include the disparity in housing conditions between Indigenous and non-Indigenous children, the impact of homelessness on children and measuring the impacts of housing affordability stress on child development

An investigation towards hostel space allocation problem with stochastic algorithms

This research presents the study of stochastic algorithms in one of the limited study in Space Allocation Problem. The domain involves the allocation of students into the available rooms which is known as Hostel Space Allocation Problem. The problem background of this domain which related with hard constraints and soft constraints are discussed and the formal mathematical models of constraints in Universiti Malaysia Sabah Labuan International Campus are presented. The construction of initial solution is handled by Constraint Programming algorithm. Two algorithms mainly Great Deluge with linear and non-linear decay rate and Simulated Annealing with linear reduction are proposed to improve the quality of solution. The experimental results show that Simulated Annealing with linear reduction temperature performs well in this domain

Comparison of lipid membrane-water partitioning with various organic solvent-water partitions of neutral species and ionic species: Uniqueness of cerasome as a model for the stratum corneum in partition processes

YesLipid membrane-water partitions (e.g., immobilized artificial membrane systems where the lipid membrane is a neutral phospholipid monolayer bound to gel beads) were compared to various organic solvent-water partitions using linear free energy relationships. To this end, we also measured the retention factors of 36 compounds (including neutral and ionic species) from water to liposomes made up of 3-sn-phosphatidylcholine and 3-sn-phosphatidyl-l-serine (80:20, mol/mol), employing liposome electrokinetic chromatography in this work. The results show that lipid membranes exhibit a considerably different chemical environment from those of organic solvents. For both neutral species and ionic species, partitions into the more polar hydroxylic solvents are chemically closer to partition into the lipid membrane as compared to partitions into the less polar hydroxylic solvents and into aprotic solvents. This means that solutes partition into the polar parts of lipid membranes, regardless of whether they are charged or not. In addition, cerasome (i.e., liposome composed mainly of stratum corneum lipids) was compared with regular phospholipid liposomes as a possible model for human stratum corneum in partitions. It was found that the cerasome-water partition exhibits a better chemical similarity to skin permeation. This is probably due to the unique structures of ceramides that occur in cerasome and in the stratum corneum lipid domain. We further show that membranes in membrane-water partitions exhibit very different properties

Tracking and predicting the treatment adherence of patients under rehabilitation: a three-wave longitudinal validation study for the Rehabilitation Adherence Inventory

This study aimed to develop and validate a new measurement tool, the Rehabilitation Adherence Inventory (RAI), to measure patients’ rehabilitation adherence. We recruited 236 patients with anterior cruciate ligament (ACL) ruptures from the United Kingdom (Mage = 33.58 ± 10.03, range = 18 to 59; female = 46.2%). Participants completed a survey, that measured their rehabilitation adherence, rehabilitation volume, psychological needs support, autonomous motivation, and intention at baseline, and at the 2nd and 4th month. Factorial, convergent, discriminant, concurrent, predictive, ecological validity and test–retest reliability of the RAI were tested via exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modelling (SEM). All the EFAs, CFAs, and SEMs yielded acceptable to excellent goodness-of-fit, χ2 = 10.51 to 224.12, df = 9 to 161, CFI > 0.95, TLI > 0.95, RMSEA <0.09 [90%C I < 0.06 to 0.12], SRMR <0.04. Results fully supported the RAI’s factorial, convergent, discriminant, and ecological validity, and test–retest reliability. The concurrent and predictive validity of the RAI was only partially supported because the RAI scores at baseline was positively associated with rehabilitation frequency at all time points (r = 0.34 to 0.38, p < 0.001), but its corresponding associations with rehabilitation duration were not statistically significant (p = 0.07 to 0.93). Overall, our findings suggest that this six-item RAI is a reliable and valid tool for evaluating patients’ rehabilitation adherence

Facial deformation following treatment for pediatric head and neck rhabdomyosarcoma; the difference between treatment modalities. Results of a trans-Atlantic, multicenter cross-sectional cohort study

Background: The four different local therapy strategies used for head and neck rhabdomyosarcoma (HNRMS) include proton therapy (PT), photon therapy (RT), surgery with radiotherapy (Paris-method), and surgery with brachytherapy (AMORE). Local control and survival is comparable; however, the impact of these different treatments on facial deformation is still poorly understood. This study aims to quantify facial deformation and investigates the differences in facial deformation between treatment modalities. Methods: Across four European and North American institutions, HNRMS survivors treated between 1990 and 2017, more than 2 years post treatment, had a 3D photograph taken. Using dense surface modeling, we computed facial signatures for each survivor to show facial deformation relative to 35 age–sex–ethnicity-matched controls. Additionally, we computed individual facial asymmetry. Findings: A total of 173 HNRMS survivors were included, survivors showed significantly reduced facial growth (p <.001) compared to healthy controls. Partitioned by tumor site, there was reduced facial growth in survivors with nonparameningeal primaries (p =.002), and parameningeal primaries (p ≤.001), but not for orbital primaries (p =.080) All patients were significantly more asymmetric than healthy controls, independent of treatment modality (p ≤.001). There was significantly more facial deformation in orbital patients when comparing RT to AMORE (p =.046). In survivors with a parameningeal tumor, there was significantly less facial deformation in PT when compared to RT (p =.009) and Paris-method (p =.007). Interpretation: When selecting optimal treatment, musculoskeletal facial outcomes are an expected difference between treatment options. These anticipated differences are currently based on clinicians’ bias, expertise, and experience. These data supplement clinician judgment with an objective analysis highlighting the impact of patient age and tumor site between existing treatment options

Understanding the genetic complexity of puberty timing across the allele frequency spectrum

Pubertal timing varies considerably and is associated with later health outcomes. We performed multi-ancestry genetic analyses on ~800,000 women, identifying 1,080 signals for age at menarche. Collectively, these explained 11% of trait variance in an independent sample. Women at the top and bottom 1% of polygenic risk exhibited ~11 and ~14-fold higher risks of delayed and precocious puberty, respectively. We identified several genes harboring rare loss-of-function variants in ~200,000 women, including variants in ZNF483, which abolished the impact of polygenic risk. Variant-to-gene mapping approaches and mouse gonadotropin-releasing hormone neuron RNA sequencing implicated 665 genes, including an uncharacterized G-protein-coupled receptor, GPR83, which amplified the signaling of MC3R, a key nutritional sensor. Shared signals with menopause timing at genes involved in DNA damage response suggest that the ovarian reserve might signal centrally to trigger puberty. We also highlight body size-dependent and independent mechanisms that potentially link reproductive timing to later life disease
