THE IMPACT OF SOCIAL SUPPORT AND FAMILY RESILIENCE ON PARENTAL STRESS IN FAMILIES WITH A CHILD DIAGNOSED WITH AN AUTISM SPECTRUM DISORDER

Families of children with autism spectrum disorders (ASD) experience significant stress relative to other families. To date, little research has examined the relationship between social support, family resilience and parental stress in families with a child diagnosed with ASD. This study explored the links between perceived social support, family resilience and parental stress in a sample of 50 primary caregivers of children between the ages of 6 and 12 diagnosed with ASD. The Social Support Index (SSI), Family Resilience Assessment Scale (FRAS), and the Parenting Stress Index-Short Form (PSI-SF) were used in this cross-sectional study. Results indicate that most families experienced clinically high levels of stress. Greater family resilience was associated with lower levels of stress. Unexpectedly, higher levels of perceived social support were associated with increased parental stress. This may suggest that families who are experiencing clinically significant levels of stress seek out community supports at higher rates than other families. It may also suggest that some social connections - such as attending religious services and parenting groups - may potentially elevate stress in parents of children with ASD. This and other possibilities are explored with implications for social work intervention. The findings of this study shed new light on the role of social support and family resilience on parental stress in families with a child diagnosed with ASD. Since the results of this study show that more resilient families report less parental stress clinicians need to focus on programming for families that enhance key processes of family resilience and reduce stress

Antiferromagnetic and Orbital Ordering on a Diamond Lattice Near Quantum Criticality

We present neutron scattering measurements on powder samples of the spinel FeSc2S4 that reveal a previously unobserved magnetic ordering transition occurring at 11.8(2)~K. Magnetic ordering occurs subsequent to a subtle cubic-to-tetragonal structural transition which distorts Fe coordinating sulfur tetrahedra lifting the orbital degeneracy. The application of 1~GPa hydrostatic pressure appears to destabilize this N\'eel state, reducing the transition temperature to 8.6(8)~K and redistributing magnetic spectral weight to higher energies. The relative magnitudes of ordered $\langle m \rangle^2\!=\!3.1(2)$ and fluctuating moments $\langle \delta m \rangle^2\!=\!13(1)$ show that the magnetically ordered ground state of FeSc2S4 is drastically renormalized and in proximity to criticality.Comment: 16 pages, 12 figure

Single spin-polarised Fermi surface in SrTiO3_3 thin films

The 2D electron gas (2DEG) formed at the surface of SrTiO$_3$(001) has attracted great interest because of its fascinating physical properties and potential as a novel electronic platform, but up to now has eluded a comprehensible way to tune its properties. Using angle-resolved photoemission spectroscopy with and without spin detection we here show that the band filling can be controlled by growing thin SrTiO$_3$ films on Nb doped SrTiO$_3$(001) substrates. This results in a single spin-polarised 2D Fermi surface, which bears potential as platform for Majorana physics. Based on our results it can furthermore be concluded that the 2DEG does not extend more than 2 unit cells into the film and that its properties depend on the amount of SrO$_x$ at the surface and possibly the dielectric response of the system

Evolution from a nodeless gap to d(x2-y2) form in underdoped La(2-x)SrxCuO4

Using angle-resolved photoemission (ARPES), it is revealed that the low-energy electronic excitation spectra of highly underdoped superconducting and non-superconducting La(2-x)SrxCuO4 cuprates are gapped along the entire underlying Fermi surface at low temperatures. We show how the gap function evolves to a d(x2-y2) form as increasing temperature or doping, consistent with the vast majority of ARPES studies of cuprates. Our results provide essential information for uncovering the symmetry of the order parameter(s) in strongly underdoped cuprates, which is a prerequisite for understanding the pairing mechanism and how superconductivity emerges from a Mott insulator.Comment: 5 pages, 4 figure

Project-Risk Management and Decision Analysis in Maritime Maintenance and Repair

The purpose of this paper is to provide insights regarding the implementation of using Project Risk Management (PRM) and Decision Analysis (DA) in managing projects for complex systems such as maritime vessels. The PRM approach apprehends many forms of risk both internal and external within a given project and assists the manager in determining the level of importance of each individual project phase and component to optimize project success. Ship Maintenance and Repair project decision-making requires that risk management and risk analysis techniques be applied in order to guide management in making better decisions to meet ship service life perspective. The Life Cycle Assessment (LCA) approach to project management is used to identify the short term limitations of projects with respect to a product\u27s life cycle. There are many tools and techniques to assist project managers in implementing optimal solutions, but published statistics indicate failures to meet schedules and/or budgets are still common. The methodology for reducing risk and for determining how much contingency to add to reduce residual risk to an acceptable level will be discussed herein. This paper contributes to a discussion of empirical investigation centered across the areas of Project Management, Decision-Making, Reliability Centered Maintenance and Condition-Based Management

Observation of Wannier-Stark localization at the surface of BaTiO3_3 films by photoemission

Observation of Bloch oscillations and Wannier-Stark localization of charge carriers is typically impossible in single-crystals, because an electric field higher than the breakdown voltage is required. In BaTiO$_3$ however, high intrinsic electric fields are present due to its ferroelectric properties. With angle-resolved photoemission we directly probe the Wannier-Stark localized surface states of the BaTiO$_3$ film-vacuum interface and show that this effect extends to thin SrTiO$_3$ overlayers. The electrons are found to be localized along the in-plane polarization direction of the BaTiO$_3$ film
