description: Background: Caregivers play a key role in the success of trauma-focused cognitive behavioural therapy (TF-CBT). Yet, the effect of their alliance on treatment outcomes besides the other parties in treatment has hardly been studied. Objective: This study examined the working alliance (WA) of therapists, patients and caregivers in TF-CBT and its contribution on treatment outcome over time. Methods: N = 76 children and adolescents (mean age = 12.66 years, range 7–17, M/F ratio: .43) participated in the TF-CBT arm of a randomized controlled trial. The WA was assessed with the Working Alliance Inventory Short Version (WAI-S) at two measurement points, while symptom level of posttraumatic stress symptoms (PTSS) was assessed with the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA). Paired sample t-tests, intraclass correlations (ICC), and mixed-effects regression models for longitudinal data were performed. Results: The alliance rating was high across all informants, with caregivers achieving the highest rating. The average level of cross-informant agreement on the alliance was low between therapists and caregivers (ICC = .26) and moderate between therapists and patients (ICC =.65). A significant contribution of an alliance improvement to the reduction of PTSS over time was found in each of the two tested models: therapists with patients model (b = .682) and therapists with caregivers model (b = .807). However, these effects were not detected with all four perspectives in one comprehensive model. Conclusion: In summary, the potential of caregivers’ views should receive more attention in the therapeutic process of trauma-focused therapy.

description: Protoplanets growing within the protoplanetary disk by pebble accretion acquire hydrostatic gas envelopes. Due to accretion heating, the temperature in these envelopes can become high enough to sublimate refractory minerals which are the major components of the accreted pebbles. Here we study the sublimation of different mineral species and determine whether sublimation plays a role during the growth by pebble accretion. For each snapshot in the growth process, we calculate the envelope structure and sublimation temperature of a set of mineral species representing different levels of volatility. Sublimation lines are determined using and equilibrium scheme for the chemical reactions responsible for destruction and formation of the relevant minerals. We find that the envelope of the growing planet reaches temperatures high enough to sublimate all considered mineral species when the mass is larger than 0.4 Earth masses. The sublimation lines are located within the gravitionally bound envelope of the planet. We make a detailed analysis of the sublimation of FeS at around 720 K, beyond which the mineral is attacked by H2 to form gaseous H2S and solid Fe. We calculate the sulfur concentration in the planet under the assumption that all sulfur released as H2S is lost from the planet by diffusion back to the protoplanetary disk. Our calculated values are in good agreement with the slightly depleted sulfur abundance of Mars, while the model overpredicts the extensive sulfur depletion of Earth by a factor of approximately 2. We show that a collision with a sulfur-rich body akin to Mars in the moon-forming impact lifts the Earth's sulfur abundance to approximately 10% of the solar value for all impactor masses above 0.05 Earth masses.

description: In this work, we present recent results of lifetime optimization for nano-structured black silicon and its
photovoltaic applications. Black silicon nano-structures provide significant reduction of silicon surface reflection due
to highly corrugated nanostructures with excellent light trapping properties. We applied reactive ion etching technology
at -20ºC to create nano-structures on silicon samples and obtained an average reflectance below 0.5%. For passivation
purposes, we used 37 nm ALD Al2O3 films. Lifetime measurements resulted in 1220 μs and to 4170 μs for p- and ntype
CZ silicon wafers, respectively. This is promising for use of black silicon RIE nano-structuring in a solar cell
process flow.

description: Although the quality of quantum bits (qubits) and quantum gates has been steadily improving, the available quantity of qubits has increased quite slowly. To address this important issue in quantum computing, we have demonstrated arbitrary single qubit gates based on targeted phase shifts, an approach that can be applied to atom, ion or other atom-like systems. These gates are highly insensitive to addressing beam imperfections and have little crosstalk, allowing for a dramatic scaling up of qubit number. We have performed gates in series on 48 individually targeted sites in a 40% full $5\times 5\times 5$ 3D array created by an optical lattice. Using randomized benchmarking, we demonstrate an average gate fidelity of 0.9962(16), with an average crosstalk fidelity of 0.9979(2).

description: Copper-plated contacts have the potential to dominate metallisation for silicon solar cells if durability concerns relating
to the metal’s adhesion strength can be addressed. In this work, a range of approaches were used for forming the plated metal/Si
interface but with no discernable difference resulting in the corresponding metal adhesion strength, even though this metal/Si
interface was shown to be the weakness in each case. Importantly, the volume of plated metal gave a much stronger correlation with
adhesion strength, suggesting that internal stresses within the plated metal, possible partly linked to the thermal expansion mismatch
between the metal and the silicon, was having significant impact on the resulting Ni/Si interfacial strength. To overcome the impact
of such variability, a new approach capable of ensuring good adhesion strength for plated contacts was developed. It involves the
formation of laser-ablated anchor points in the heavily-doped silicon surface which when plated greatly strengthen the metal’s
mechanical adhesion strength.

description: This paper studies a two-phase material with a microstructure composed of a hard brittle reinforcement phase embedded in a soft ductile matrix. It addresses the full three-dimensional nature of the microstructure and macroscopic deformation. A large ensemble of periodic microstructures is used, whereby the individual grains of the two phases are modeled using equi-sized cubes. A particular solution strategy relying on the Fast Fourier Transform is adopted, which has a high computational efficiency both in terms of speed and memory footprint, thus enabling a statistically meaningful analysis. This solution method naturally accompanies the regular microstructural model, as the Fast Fourier Transform relies on a regular grid. Using the many considered microstructures as an ensemble, the average arrangement of phases around fracture initiation sites is objectively identified by the correlation between microstructure and fracture initiation -- in three dimensions. The results show that fracture initiates where regions of the hard phase are interrupted by bands of the soft phase that are aligned with the direction of maximum shear. In such regions, the hard phase is arranged such that the area of the phase boundary perpendicular to the principal strain direction is maximum, leading to high hydrostatic tensile stresses, while not interrupting the shear bands that form in the soft phase. The local incompatibility that is present around the shear bands is responsible for a high plastic strain. By comparing the response to a two-dimensional microstructure it is observed that the response is qualitatively similar (both macroscopically and microscopically). One important difference is that the local strain partitioning between the two phases is over-predicted by the two-dimensional microstructure, leading to an overestimation of damage.

description: Aims. The evolutionary status of the blue supergiant Sher 25 and its membership to the massive cluster NGC 3603 are investigated. Methods. A hybrid non-LTE (local thermodynamic equilibrium) spectrum synthesis approach is employed to analyse a high-resolution optical spectrum of Sher 25 and five similar early B-type comparison stars in order to derive atmospheric parameters and elemental abundances. Fundamental stellar parameters are determined by considering stellar evolution tracks, Gaia Data Release 3 (DR3) data and complementary distance information. Interstellar reddening and the reddening law along the sight line towards Sher 25 are constrained employing UV photometry for the first time in addition to optical and infrared data. The distance to NGC 3603 is reevaluated based on Gaia DR3 data of the innermost cluster O-stars. Results. The spectroscopic distance derived from the quantitative analysis implies that Sher 25 lies in the foreground of NGC 3603, which is found to have a distance of $d_\mathrm{NGC 3603}$ = 6250$\pm$150 pc. A cluster membership is also excluded as the hourglass nebula is unaffected by the vigorous stellar winds of the cluster stars and from the different excitation signatures of the hourglass nebula and the nebula around NGC 3603. Sher 25 turns out to have a luminosity of log L/L$_\odot$ = 5.48$\pm$0.14, equivalent to that of a $\sim$27 $M_\odot$ supergiant in a single-star scenario, which is about half of the mass assumed so far, bringing it much closer in its characteristics to Sk-69°202, the progenitor of SN 1987A. Sher 25 is significantly older than NGC 3603. Further arguments for a binary (merger) evolutionary scenario of Sher 25 are discussed.

description: Background: Psychological traumatic experiences can lead to posttraumatic stress disorder (PTSD). Secondary psychotic symptoms are not common but may occur. Objectives: Since psychotic symptoms of schizophrenia have been related to aberrant reward processing in the striatum, using the same paradigm we investigate whether the same finding extends to psychotic and anhedonic symptoms in PTSD. Methods: A total of 70 male refugees: 18 PTSD patients with no secondary psychotic symptoms (PTSD-NSP), 21 PTSD patients with secondary psychotic symptoms (PTSD-SP), and 31 healthy controls (RHC) were interviewed and scanned with functional magnetic resonance imaging (fMRI) during a monetary incentive delay task. Using region of interest analysis of the prefrontal cortex and ventral striatum, we investigated reward-related activity. Results: Compared to RHC, participants with PTSD had decreased neural activity during monetary reward. Also, participants with PTSD-SP exhibited decreased activity in the associative striatum relative to participants with PTSD-NSP during processing of motivational reward anticipation which correlated with severity of psychotic symptoms. However, the difference between the two PTSD groups disappeared when PTSD severity and trauma exposure were accounted for. Conclusions: Anhedonia and secondary psychotic symptoms in PTSD are characterized by dysfunctional reward consumption and anticipation processing, respectively. The latter may reflect a mechanism by which abnormal reward signals in the basal ganglia facilitates psychotic symptoms across psychiatric conditions.

description: Atomic layer deposited aluminum oxide has been widely used as a low deposition temperature
alternative material for surface passivation in the area of high efficiency silicon solar cells. Al2O3 thin films provide
an excellent passivation quality due to chemical and field effect passivation. Fabrication of back side passivated
silicon solar cells requires a complex patterning for metal contact, however, ultra-thin Al2O3 enables tunneling and
hence avoid the complexity of metal contacts. Reducing the thickness of Al2O3 results in deterioration of the
passivation quality. Thus, in this work, we develop doped hydrogenated amorphous silicon (a-Si:H)/sub-nm Al2O3
stack which compensates the passivation quality deterioration and maintains the tunneling to achieve back side
passivated contact. The improvement of the surface passivation and tunneling has been observed, since the lifetime of
the stack of doped a-Si:H/Al2O3 is from three to four times higher than Al2O3 reference samples. To investigate the
impact of the developed stack, we incorporated the measured surface recombination velocity and contact resistance
into PC-1D simulation to compare passivated contact to point contact solar cell. The simulation shows that our
passivated contact has a potential to improve the solar cell performance without the need to complicated patterning.

description: Recent cosmic microwave background data in temperature and polarization have reached high precision in estimating all the parameters that describe the current so-called standard cosmological model. Recent results about the integrated Sachs-Wolfe effect from cosmic microwave background anisotropies, galaxy surveys, and their cross-correlations are presented. Looking at fine signatures in the cosmic microwave background, such as the lack of power at low multipoles, the primordial power spectrum and the bounds on non-Gaussianities, complemented by galaxy surveys, we discuss inflationary physics and the generation of primordial perturbations in the early Universe. Three important topics in particle physics, the bounds on neutrinos masses and parameters, on thermal axion mass and on the neutron lifetime derived from cosmological data are reviewed, with attention to the comparison with laboratory experiment results. Recent results from cosmic polarization rotation analyses aimed at testing the Einstein equivalence principle are presented. Finally, we discuss the perspectives of next radio facilities for the improvement of the analysis of future cosmic microwave background spectral distortion experiments.

description: Persistent homology analysis, a recently developed computational method in algebraic topology, is applied to the study of the phase transitions undergone by the so-called XY-mean field model and by the phi^4 lattice model, respectively. For both models the relationship between phase transitions and the topological properties of certain submanifolds of configuration space are exactly known. It turns out that these a-priori known facts are clearly retrieved by persistent homology analysis of dynamically sampled submanifolds of configuration space.

description: We report on the development of industrial wet chemical cleaning processes for n-type passivated emitter,
rear totally diffused (n-PERT) solar cells. PERT silicon solar cells with 22% efficiency have been manufactured
comparing established silicon surface cleaning processes like sulfuric ozone mixture (SOM) with novel wet chemical
processes based on DI water/ozone (DIW/O3) and industrial cleaning processes like diluted hydrochloric
acid/hydrofluoric acid mixture (HCl/HF) as used in solar cell mass production. We have tested the different wet chemical
cleaning methods on prominent metal impurities like Fe and Cu. These metals typically occur on the silicon wafer surface
after alkaline processing like saw damage etch and texturing. It has been shown that the impurity removal efficiency of
the different cleaning methods is varying strongly for different metals. This information is used for optimizing wet
chemical cleaning processes in terms of bath lifetime and chemical consumption reduction. In this paper the results of the
metal removal efficiency study is applied to a n-PERT solar cell process flow, but it could be applied on other high
efficiency cells concepts like IBC or HIT as well.

description: The ALICE Collaboration measures the production of low-mass dielectrons in pp, p-Pb and Pb-Pb collisions at the LHC. The main detectors used in the analyses are the Inner Tracking System, Time Projection Chamber and Time-Of-Flight detector, all located at mid-rapidity. The dielectron yield in p-Pb collisions shows an overall agreement with the hadronic cocktail. The pair transverse momentum distributions are sensitive to the contributions from open heavy-flavours. In Pb-Pb collisions, uncorrected background-subtracted yields have been extracted in two centrality classes. In pp collisions the production of virtual photons relative to the inclusive yield is determined by analyzing the dielectron excess with respect to the expected hadronic sources. The direct photon cross section is then calculated and found to be in agreement with NLO pQCD calculations. A feasibility study for LHC Run 3 after the ALICE upgrade indicates the possibility for a future measurement of the early effective temperature.

description: Understanding the mechanisms of magnetoelectric (ME) coupling within multiferroic structures is paramount from a fundamental as well as an applied point of view. We report here that the magnetoelectric properties, as well as the magnetization, of BaTiO$_3$-BiFeO$_3$ superlattices can be tuned by varying the BiFeO$_3$ layer thickness. The magnetoelectric voltage coefficient ($α_{ME}$) reaches its maximum of 60.2 Vcm$^{-1}$Oe$^{-1}$ at 300 K, one of the highest values reported so far, for a sample with a BiFeO$_3$ thickness of 5 nm and a BaTiO$_3$ thickness of 10 nm. To gain deeper insight into the increased magnetoelectric coupling, and both the local and macroscopic magnetic properties, samples with varying BiFeO$_3$ thicknesses have been investigated. Correlations were established between the hyperfine field (HFF), the magnetoelectric voltage coefficient and the magnetization. The possible mechanisms responsible for the strong magnetoelectric coupling are discussed.

description: Background: Schizophrenia spectrum disorders (SSD) are mental diseases caused by a combination of genetic susceptibility and a number of environmental factors. Among these factors, the role of traumatic events suffered in childhood, as well as that of substance use, have been of particular research interest. Objectives: To conduct a systematic review to clarify whether there is an interaction between childhood trauma and substance use related to the diagnosis or symptoms of SSD. It was also the objective of this review to collate the associations that may exist between the three variables of the study (trauma, substance use and psychosis). Methods: We conducted a systematic search resulting in 240 articles. We considered all of the original articles that explored childhood trauma and substance use in patients suffering from SSD. Results: Twenty-three articles were selected for this review. Several of the reviewed papers found associations between childhood trauma and substance use with SSD, as well as interactions between trauma and drug use on SSD. Conclusions: The results suggest that childhood trauma and substance use may be present at the basis of psychosis. This double hit on the pathogenesis could have clinical implications, since each of these impacts could be considered a window of opportunity for the primary prevention of SSD.
A method for the numerical analysis of combustion instabilities with an application to afterburner screech

description: This work concerns the prediction of potentially damaging thermoacoustic oscillations in gas turbine combustion systems by computational means. A framework is laid out to predict numerically the frequency and stability of thermoacoustic oscillations, with focus on the high frequency screech instability of afterburners. A hybrid numerical method is used that includes separate calculations of the mean flow and of the perturbed field due to the acoustic oscillations. This modularity supports the choice of models that are the most appropriate for combustion and for acoustic wave propagation, which are the processes that make up the feedback mechanism that can lead to the establishment of an instability. This gives flexibility, improved accuracy and more insight into the physics of the thermoacoustic system at a potentially reduced computational cost. The mechanism leading to screech involves the formation of vortices induced by acoustic transverse modes at the afterburner flameholder. These vortices trap fresh reactants that burn after a certain time delay, therefore feeding energy into the oscillation. Within a linear approximation, the effect of small amplitude acoustic fluctuations on the flame is studied by perturbing harmonically the transverse velocity at the flameholder lip over a range of frequencies using forced combustion CFD calculations. The response in heat release rate, which is a thermoacoustic source of sound, is represented by a flame transfer function (FTF). It is argued that for the investigation of screech oscillations, this FTF must be multidimensional because of the transverse nature of the acoustic oscillation. For fully premixed flames, the main contributor to heat release rate fluctuations is the variation in flame surface area. This information is used to develop a novel flame model that represents the multidimensional, frequency dependent response of the flame to velocity perturbations. Compared to FTFs, which require computationally expensive forced calculations, this model has the advantage of providing the frequency dependent flame response as part of the acoustic calculation. After verification and validation of each of the tools used for the acoustic and combustion simulations, this flame model is used in the analysis of a simplified afterburner, where a high frequency, radial and longitudinal resonant mode was computed. Convective modes, which are important in the prediction of the frequency of thermoacoustic oscillations are predicted as a result of the interaction between the acoustic wave and the flame.

This situation is mostly caused by a lack of observations, owing to their location in the near-infrared regime, which is covered by few high-resolution spectrographs. We study the Pa$β$ line, using a sample of 360 M~dwarfs observed by the CARMENES spectrograph. Descending the spectral sequence of inactive M~stars in quiescence, we find the Pa$β$ line to get shallower until about spectral type M3.5 V, after which a slight re-deepening is observed. Looking at the whole sample, for stars with H$α$ in absorption, we find a loose anti-correlation between the (median) pseudo-equivalent widths (pEWs) of H$α$ and Pa$β$ for stars of similar effective temperature. Looking instead at time series of individual stars, we often find correlation between pEW(H$α$) and pEW(Pa$β$) for stars with H$α$ in emission and an anti-correlation for stars with H$α$ in absorption. Regarding flaring activity, we report the automatic detection of 35 Paschen line flares in 20 stars. Additionally we found visually six faint Paschen line flares in these stars plus 16 faint Paschen line flares in another 12 stars. In strong flares, Paschen lines can be observed up to Pa 14. Moreover, we find that Paschen line emission is almost always coupled to symmetric H$α$ line broadening, which we ascribe to Stark broadening, indicating high pressure in the chromosphere. Finally we report a few Pa$β$ line asymmetries for flares that also exhibit strong H$α$ line asymmetries.

description: In this contribution, the wet chemical saw damage removal (SDR) and texturing of crystalline silicon
wafers are replaced by maskless inductively coupled plasma (ICP) processes. For the SDR, an isotropic ICP process is
applied with SF6 as etch gas leading to semicircle surface structures with few microns width. Subsequently, an
anisotropic ICP texturing is performed with SF6/O2 forming parabolic like surface structures with lateral extent of approx.
500 nm. A superposition of nanotexture on the SDR microtexture is performed. Optical measurements reveal an average
reflection of 3.71 %, transmission of 1.31 % and absorption of 94.98 % integrated from 200-1120 nm under a normal
incidence of light after PECVD SiNx passivation. SEM images show a homogenous 70 nm SiNx deposition on the ICP
textures. A sufficient passivation is achieved by ICP SF6 SDR with approx. 100 μs effective minority carrier lifetime at
1015 cm-3 minority carrier density (MCD). In combination with the ICP SF6/O2 texture, the samples have approx. 70 μs
effective minority carrier lifetime at 1015 cm-3 MCD.

description: The diversity of T-cell receptors recognizing foreign pathogens is generated through a highly stochastic recombination process, making the independent production of the same sequence rare. Yet unrelated individuals do share receptors, which together constitute a "public" repertoire of abundant clonotypes. The TCR repertoire is initially formed prenatally, when the enzyme inserting random nucleotides is downregulated, producing a limited diversity subset. By statistically analyzing deep sequencing T-cell repertoire data from twins, unrelated individuals of various ages, and cord blood, we show that T-cell clones generated before birth persist and maintain high abundances in adult organisms for decades, slowly decaying with age. Our results suggest that large, low-diversity public clones are created during pregnancy, and survive over long periods, providing the basis of the public repertoire.

description: These last years several Systems with Tightly packed Inner Planets in the super-Earth mass regime have been discovered harboring chains of resonances. It is generally believed that planet pairs get trapped in MMR during the migration phase in the protoplanetary disk, while the tides raised by the host star provide a source of dissipation on very long timescales. In this work, we aim to study the departure from exact commensurabilities observed among the STIPs which harbor 3-planet resonances and analyze how tides play an important role in shaping the resonance offsets for the STIPs. We analyzed the resonance offsets between adjacent pairs for five multi-planetary systems, namely Kepler-80, Kepler-223, K2-138, TOI-178, and TRAPPIST-1, highlighting the existence of different trends in the offsets. On the one hand, we derived analytical estimates for the offsets, which confirm that the departure of the planetary pairs from the nominal MMRs are due to the 3-planet resonant dynamics. On the other hand, we performed N-body simulations including both orbital migration and tidal dissipation from the host star with simple prescriptions in order to test the effectiveness of this mechanism at shaping the observed trend in the offsets, focusing our study on the preservation of the resonant patterns in the different systems with the same general setup. We found that the trends in the offsets of the five detected systems can be produced by tidal damping effects, regardless of the considered value for the tidal factor. It is a robust mechanism that relaxes the system towards equilibrium while efficiently moving it along 3-planet resonances, which induces the observed resonance offset for each planet pair. In addition, we showed that for Kepler-80, K2-138, and TOI-178, the amplitudes of the resonant offsets can also be reproduced with appropriate tidal factor, for the estimated age of the systems.

description: Surface recombination remains a major factor limiting the efficiency of silicon solar cells. The postprocessing
of dielectric films used as surface coatings has been previously demonstrated an effective technique to
improve their passivation quality. In this paper extrinsic methods are demonstrated to produce the lowest reported
surface recombination velocity in solar relevant n-type silicon. Recombination velocities below 2.8 cm/s at an injection
of 1015 cm-3, are achieved using extrinsic field-effect passivation, or < 0.6 cm/s when using combined extrinsic chemical
and extrinsic field effect passivation. These are equivalent to emitter saturation current densities J0e<1.4 fA/cm2 and
0.6 fA/cm2.
Inclusive Outreach Matters

Subjects: subject: Diversity in the workplace
subject: Library outreach programs

description: In this keynote, Felicia Smith will share examples of outreach efforts she conducted for libraries, that included the Office of Accessibility, First-Generation and/or Low-Income (FLI) students, incarcerated juveniles, Historically Black Colleges and Universities (HBCU) and underrepresented minority students. Inclusive outreach and engagement with diverse communities is important and can easily be incorporated into everyday librarianship with just a little imagination and a minimal amount of effort. It is helpful to start by conducting an environmental scan of campus and identifying opportunities for outreach. It is vital to compose a measurable set of objectives, and clearly articulate what will be achieved, including a way to assess outcomes. It is also important to understand the differences between inclusion and diversity, which are misused interchangeably. Felicia Smith’s mission as the only Racial Justice & Social Equity Librarian is to highlight communities that have been systematically devalued resulting in underrepresentation in scholarly settings and publications. This is problematic because important communities are being “disappeared” from the historical narrative, leading to a distorted interpretation of the past that then leads to dangerous implications for the present. Simply put, lack of inclusion matters. The goal of this keynote is to encourage attendees to amplify notable voices that have been intentionally silenced – so that those voices can be heard; and to make the excluded or unseen – seen.

description: We consider dipolar excitations propagating via dipole-induced exchange among immobile molecules randomly spaced in a lattice. The character of the propagation is determined by long-range hops (Levy flights). We analyze the eigen-energy spectra and the multifractal structure of the wavefunctions. In 1D and 2D all states are localized, although in 2D the localization length can be extremely large leading to an effective localization-delocalization crossover in realistic systems. In 3D all eigenstates are extended but not always ergodic, and we identify the energy intervals of ergodic and non-ergodic states. The reduction of the lattice filling induces an ergodic to non-ergodic transition, and the excitations are mostly non-ergodic at low filling.

description: In this study, AlOx layers have been deposited using an industrial-type PECVD TwynTM system from
the SEMCO Technologies Company. Excellent passivation properties were obtained with i-Voc over 700 mV (SRV
< 20 cm/s) demonstrated on symmetrical passivated p-type wafers covered with AlOx/SiNx stacks. These values are
very close to those obtained with the AlOx layers deposited by ALD and meet the quality requirements for the
backside passivation of p-type PERC cells. We have demonstrated that the post annealing of the AlOx layer has a
very weak influence on the passivation quality of SiNx capped AlOx layer, thus the SiNx capping layer can be
deposited in the same run as the AlOx layer leading to significant equipment investment and footprint reduction
compared to ALD systems.

description: First Nations people are the most informed culturally and have the greatest capacity to engage with First Nations NDIS participants. But in the categories of skills recognised by the NDIS First Nations people’s cultural and communication capacity is not recognised, so they are often excluded from providing information on assessments and identifying support needs. Moreover, the categories of people (professions) who are recognised by the NDIS and enabled to speak about First Nations people often do not have these skills or knowledge. Their professional training and experience generally does not equip them to understand important cultural factors or communication issues important in working with First Nations people with disabilities. Thus we make the proposition that ‘those that know mostly can’t speak, those that can speak mostly don’t know’, in relation to important cultural and communication information on First Nations NDIS participants. This document describes the context of this proposition based on our experience in working as a bicultural team with First Nations NDIS participants. This document was first developed as a training resource for Northern Territory Public Guardians and is part of training provided to NDIS service providers.
