description: Purpose: We extended our earlier study on normative growth curves for intelligibility development in typical children from 30 to 119 months of age. We also determined quantile-specific age of steepest growth and growth rates. A key goal was to establish age-specific benchmarks for single-word and multiword intelligibility.Method: This cross-sectional study involved collection of in-person speech samples from 538 typically developing children (282 girls and 256 boys) who passed speech, language, and hearing screening measures. One thousand seventy-six normal-hearing naïve adult listeners (280 men and 796 women) orthographically transcribed children’s speech. Speech intelligibility was measured as the percentage of words transcribed correctly by naive adults, with single-word and multiword intelligibility outcomes modeled separately.Results: The age range for 50% single-word intelligibility was 31–47 months (50th–5th percentiles), the age range for 75% single-word intelligibility was 49–87 months, and the age range for 90% intelligibility for single words was 83–120+ months. The same milestones were attained for multiword intelligibility at 34–46, 46–61, and 62–87 months, respectively. The age of steepest growth for the 50th percentile was 30–31 months for both single-word and multiword intelligibility and was later for children in lower percentiles. The maximum growth rate was 1.7 intelligibility percentage points per month for single words and 2.5 intelligibility percentage points per month for multiword intelligibility.Conclusions: There was considerable variability in intelligibility development among typical children. For children in median and lower percentiles, intelligibility growth continues through 9 years. Children should be at least 50% intelligible by 48 months.

description: Opioid use disorder (OUD) affects people across the continuum of life, in all geographic locations, irrespective of gender, age, nationality, and socioeconomic status. From January to March 2021, 1792 opioid toxicity deaths occurred in Canada. As front-line healthcare professionals, nurses make substantial contributions toward the prevention, treatment, and management of OUD. However, little research has been conducted regarding the role and impact of the nurses working in these unique practice settings. Using focused ethnography, this qualitative study aimed to explore the understanding of the role and impact of the nurse working in OUD treatment. Individual in-depth interviews were conducted with ten registered nurses who worked across the spectrum of OUD treatment. Analysis of the qualitative data revealed six themes to better understand the role and impact of the nurse: (a) the art of addiction nursing, (b) direct patient care, (c) indirect patient care, (d) the shared experience of stigma, (e) perceived barriers, and (f) looking to the (uncertain) future. The present study offered several implications for nursing practice, education, and research. Study results identify similarities and differences of the role of the nurse working across a variety of treatment programs; future research opportunities exist to explore the role of the nurse in specific OUD treatment programs, and the role of the nurse in OUD treatment transnationally. Nurses working in this practice area are hardworking, compassionate, and deeply committed to providing high-quality healthcare to patients with OUD across various practice areas. Despite this, nurse participants emphasized perceived challenges and barriers that negatively impacted their ability to meet patient’s needs.

description: The adiabatic sound velocity and compressibility for harmonically trapped ideal anyons in arbitrary dimensions are calculated within Haldane fractional exclusion statistics. The corresponding low-temperature and high-temperature behaviors are studied in detail. To compare with the experimental result of unitary fermions, the sound velocity for anyons in the cigar-shaped trap is derived. The sound velocity for anyons in the disk-shaped trap is also calculated. With the parameter g=0.287, the sound velocity of unitary fermions in the cigar-shaped trap modeled by anyons is in good agreement with the experimental result, while that of unitary fermions in the disk-shaped trap is v_{0}/v_{F}=0.406 with Fermi velocity v_{F}.

description: Heterogeneous robots equipped with multi-modal sensors (e.g., UAV, wheeled and legged terrestrial robots) provide rich and complementary functions that may help human operators to accomplish complex tasks in unknown environments. However, seamlessly integrating heterogeneous agents and making them interact and collaborate still arise challenging issues. In this paper, we define a ROS 2 based software architecture that allows to build incarnated heterogeneous multi-agent systems (HMAS) in a generic way. We showcase its effectiveness through a scenario integrating aerial drones, quadruped robots, and human operators (see https://youtu.be/iOtCCticGuk). In addition, agent spatial awareness in unknown outdoor environments is a critical step for realizing autonomous individual movements, interactions, and collaborations. Through intensive experimental measurements, RTK-GPS is shown to be a suitable solution for achieving the required locating accuracy.

description: We study a class of models for tri-bimaximal neutrino mixing in SO(10) grand unified SUSY framework. Neutrino masses arise from both type-I and type-II seesaw mechanisms. We use dimension five operators in order to not spoil tri-bimaximal mixing by means of type-I contribution in the neutrino sector. We show that it is possible to fit all fermion masses and mixings including also the recent T2K result as deviation from the tri-bimaximal.

description: A longstanding goal in legged-mobile robotics is to enable robots to learn robust control policies capable of expanding their locomotion abilities to be competent and efficient when moving on a priori unknown uneven terrains. Traditional control techniques lack the generalizability required for legged robots to locomote outside a controlled lab environment in terrains with diverse difficult-to-model uncertainties (e.g., friction coefficients, compliance/deformation, etc.). The approach presented in this thesis combines Deep Reinforcement Learning (Deep RL) with motion capture (MoCap) data to train a biped simulated agent (i.e., humanoid robot) to perform a rich repertoire of diverse skills (e.g., walking, crawling, running, climbing steps, etc.). The method begins by creating reference motion clips with the robot’s morphology for desired locomotion gaits. This is achieved by applying motion retargeting techniques to adapt MoCap clips (taken from humans) to the humanoid system. Subsequently, these adapted reference clips are used as inputs to a new Deep RL architecture. Such architecture uses the Proximal Policy Optimization (PPO) algorithm to train the simulated agent to perform the gait of interest on randomized domains that vary with each iteration. After training, the generated control policy is transferred to a real robot for testing and fine-tuning. The benefits of this approach include i) reducing the training time typically required in multi-legged systems, ii) avoiding exposing the robot and the trainer (human operator) to the tedious and time-consuming initial iterations of the learning process where mistakes are likely to happen, and iii) generalizability – the ability to employ the training model on virtually every available legged mobile robot. Thus, the proposed approach enables robots to locomote in real-world settings. The results are demonstrated through simulation and experimentally tested on a Robotis’ THORMANG 3.0 humanoid robot.

description: Continuing our previous study \cite{Du:2011se} of permutation sum of color ordered tree amplitudes of gluons, in this note, we prove the large-$z$ behavior of their cyclic sum and the combination of cyclic and permutation sums under BCFW deformation. Unlike the permutation sum, the study of cyclic sum and the combination of cyclic and permutation sums is much more difficult. By using the generalized Bern-Carrasco-Johansson (BCJ) relation, we have proved the boundary behavior of cyclic sum with nonadjacent BCFW deformation. The proof of cyclic sum with adjacent BCFW deformation is a little bit simpler, where only Kleiss-Kuijf (KK) relations are needed. Finally we have presented a new observation for partial-ordered permutation sum and applied it to prove the boundary behavior of combination sum with cyclic and permutation.

description: With the spread of robots in unstructured, dynamic environments, the topic of path replanning has gained importance in the robotics community. Although the number of replanning strategies has significantly increased, there is a lack of agreed-upon libraries and tools, making the use, development, and benchmarking of new algorithms arduous. This paper introduces OpenMORE, a new open-source ROS-based C++ library for sampling-based path replanning algorithms. The library builds a framework that allows for continuous replanning and collision checking of the traversed path during the execution of the robot trajectory. Users can solve replanning tasks exploiting the already available algorithms and can easily integrate new ones, leveraging the library to manage the entire execution.

description: For bilayer graphene in a magnetic field at the neutral point, we derive and solve a full set of gap equations including all Landau levels and taking into account the dynamically screened Coulomb interaction. There are two types of the solutions for the filling factor $ν=0$: (i) a spin-polarized type solution, which is the ground state at small values of perpendicular electric field $E_{\perp}$, and (ii) a layer-polarized solution, which is the ground state at large values of $E_{\perp}$. The critical value of $E_{\perp}$ that determines the transition point is a linear function of the magnetic field, i.e., $E_{\perp,{\rm cr}}=E_{\perp}^{\rm off}+a B$, where $E_{\perp}^{\rm off}$ is the offset electric field and $a$ is the slope. The offset electric field and energy gaps substantially increase with the inclusion of dynamical screening compared to the case of static screening. The obtained values for the offset and the energy gaps are comparable with experimental ones. The interaction with dynamical screening can be strong enough for reordering the levels in the quasiparticle spectrum (the $n=2$ Landau level sinks below the $n=0$ and $n=1$ ones).

Acoustic tagging effects on juvenile sockeye salmon swimming performance, growth, post-surgical wound healing, survival, and metabolic rate in freshwater and saltwater
Creators: name: Collins, Alison Laureen
Publisher: name: University of British Columbia
Year: 2012

description: Juvenile Pacific salmon make large-scale migrations from natal freshwater rearing grounds to the Northern Pacific Ocean. To properly manage these species an understanding of their migration patterns and survival is necessary. Acoustic telemetry is an ideal tool used to study the migratory survival and behavior of juvenile salmonids. However, the assumption that tagged individuals behave similarly to non-tagged conspecifics in the freshwater and saltwater phases of their outmigration need to be validated as part of large-scale telemetry studies. Consequently, a laboratory-based experiment was carried out to evaluate intracoelomic tagging effects on juvenile sockeye salmon (Oncorhynchus nerka) swimming performance, growth, post-surgical wound healing and survival in both freshwater and saltwater. A sub-set of fish were tagged with three differently sized tags and the response of the fish to tagging was compared to both a sham surgery and non-tagged treatment group. Fish with tag burdens greater than 6 – 8% body weight (BW; tag weighed in water) resulted in some freshwater mortality and decreased freshwater prolonged swimming performance. Fish implanted with larger tags had decreased survival in saltwater and poorer post-surgical wound healing than fish implanted with smaller tags. To minimize the negative effects of intracoelomic tagging, this research suggests that tag burdens should not exceed 6 – 8% BW in juvenile, hatchery-reared sockeye salmon. Oxygen consumption rates were measured during the transition from freshwater to saltwater to investigate the hypothesis that intracoelomic tagging affects metabolic rate in juvenile salmonids during this period. Respirometer experiments during periods of rest and recovery post-swimming were used to assess metabolic rate in freshwater and saltwater for both tagged and non-tagged treatment groups. There was no effect of intracoelomic tagging on recovery metabolic rate post-swimming. However, tagging and salinity had an affect on resting metabolic rate; when fish transitioned from freshwater to 9 ppt saltwater, resting metabolic rate significantly increased. Resting metabolic rate at 9 ppt was elevated in comparison to the lowest resting metabolic rate recorded in saltwater at 28 ppt. However, both non-tagged and tagged fish were able to recover metabolically after transitioning to saltwater, indicated by similar metabolic rate values in saltwater as in freshwater.

description: We use a path integral quantum Monte Carlo method to simulate excitons and biexcitons in core shell nanocrystals with Type-I, II and quasi-Type II band alignments. Quantum Monte Carlo techniques allow for all quantum correlations to be included when determining the thermal ground state, thus producing accurate predictions of biexciton binding. These subtle quantum correlations are found to cause the biexciton to be binding with Type-I carrier localization and strongly anti-binding with Type-II carrier localization, in agreement with experiment for both core shell nanocrystals and dot in rod nanocrystal structures. Simple treatments based on perturbative approaches are shown to miss this important transition in the biexciton binding. Understanding these correlations offers prospects to engineer strong biexciton anti-binding which is crucial to the design of nanocrystals for single exciton lasing applications.

description: Based on the discovery of the duality between Jackiw-Teitelboim quantum gravity and a double-scaled matrix ensemble by Saad, Shenker and Stanford in 2019, we show how consistency between the two theories in the universal Random Matrix Theory (RMT) limit imposes a set of constraints on the volumes of moduli spaces of Riemannian manifolds. These volumes are given in terms of polynomial functions, the Weil-Petersson volumes, solving a celebrated nonlinear recursion formula that is notoriously difficult to analyze. Since our results imply linear relations between the coefficients of the Weil-Petersson volumes, they therefore provide both a stringent test for their symbolic calculation and a possible way of simplifying their construction. In this way, we propose a long-term program to improve the understanding of mathematically hard aspects concerning moduli spaces of hyperbolic manifolds by using universal RMT results as input.

description: General formulae for the soft SUSY breaking terms, valid in any SUGRA context, were derived in the mid-nineties. Since SUSY is not expected to have quantum anomalies, they should be valid in the quantum theory and be RG invariant down to the soft SUSY breaking scale. This observation enables us to give a uniform treatment of all phenomenological models for SUSY breaking and transmission, such as AMSB, GMSB, etc. In particular we find that the much discussed RG invariant formulae for soft SUSY breaking parameters in AMSB, effectively depend on a strong assumption of factorizability of the matter Kaehler metric. We then argue that there is no necessity for having ad hoc constructions such as mAMSB to counteract the negative squared slepton mass problem, since the natural framework that emerges in a sequestered model is one in which gaugino masses are as in AMSB, and the other soft terms are generated by RG running as in gaugino mediation.

description: We have used new, deep, visible and near infrared observations of the compact starburst cluster in the giant HII region NGC 3603 and its surroundings with the WFC3 on HST and HAWK-I on the VLT to study in detail the physical properties of its intermediate mass (~ 1 - 3 M_sun) stellar population. We show that after correction for differential extinction and actively accreting stars, and the study of field star contamination, strong evidence remains for a continuous spread in the ages of pre-main sequence stars in the range ~ 2 to ~ 30 Myr within the temporal resolution available. Existing differences among presently available theoretical models account for the largest possible variation in shape of the measured age histograms within these limits. We also find that this isochronal age spread in the near infrared and visible Colour-Magnitude Diagrams cannot be reproduced by any other presently known source of astrophysical or instrumental scatter that could mimic the luminosity spread seen in our observations except, possibly, episodic accretion. The measured age spread and the stellar spatial distribution in the cluster are consistent with the hypothesis that star formation started at least 20-30 Myrs ago progressing slowly but continuously up to at least a few million years ago. All the stars in the considered mass range are distributed in a flattened oblate spheroidal pattern with the major axis oriented in an approximate South-East - North-West direction, and with the length of the equatorial axis decreasing with increasing age. This asymmetry is most likely due to the fact that star formation occurred along a filament of gas and dust in the natal molecular cloud oriented locally in this direction.

description: Our series of articles is devoted to high-precision molecular dynamics simulation of mixed actinide-oxide (MOX) fuel in the approximation of rigid ions and pair interactions (RIPI) using high-performance graphics processors (GPU). In this article we study self-diffusion mechanisms of oxygen anions in uranium dioxide (UO2) with the ten recent and widely used sets of interatomic pair potentials (SPP) under periodic (PBC) and isolated (IBC) boundary conditions. Wide range of measured diffusion coefficients (from 10^-3 cm^2/s at melting point down to 10^-12 cm^2/s at 1400 K) made possible a direct comparison (without extrapolation) of the simulation results with the experimental data, which have been known only at low temperatures (T < 1500 K). A highly detailed (with the temperature step of 1 K) calculation of the diffusion coefficient allowed us to plot temperature dependences of the diffusion activation energy and its derivative, both of which show a wide (~1000 K) superionic transition region confirming the broad lambda-peaks of heat capacity obtained by us earlier. It is shown that regardless of SPP the anion self-diffusion in model crystals without surface or artificially embedded defects goes on via exchange mechanism, rather than interstitial or vacancy mechanisms suggested by the previous works. The activation energy of exchange diffusion turned out to coincide with the anti-Frenkel defect formation energy calculated by the lattice statics.

description: We investigate regularizations of distributional sections of vector bundles by means of nets of smooth sections that preserve the main regularity properties of the original distributions (singular support, wavefront set, Sobolev regularity). The underlying regularization mechanism is based on functional calculus of elliptic operators with finite speed of propagation with respect to a complete Riemannian metric. As an application we consider the interplay between the wave equation on a Lorentzian manifold and corresponding Riemannian regularizations, and under additional regularity assumptions we derive bounds on the rate of convergence of their commutator. We also show that the restriction to underlying space-like foliations behaves well with respect to these regularizations.

description: To mitigate dictionary attacks or similar undesirable automated attacks to information systems, developers mostly prefer using CAPTCHA challenges as Human Interactive Proofs (HIPs) to distinguish between human users and scripts. Appropriate use of CAPTCHA requires a setup that balances between robustness and usability during the design of a challenge. The previous research reveals that most usability studies have used accuracy and response time as measurement criteria for quantitative analysis. The present study aims at applying optical neuroimaging techniques for the analysis of CAPTCHA design. The functional Near-Infrared Spectroscopy technique was used to explore the hemodynamic responses in the prefrontal cortex elicited by CAPTCHA stimulus of varying types. )e findings suggest that regions in the left and right dorsolateral and right dorsomedial prefrontal cortex respond to the degrees of line occlusion, rotation, and wave distortions present in a CAPTCHA. The systematic addition of the visual effects introduced nonlinear effects on the behavioral and prefrontal oxygenation measures, indicative of the emergence of Gestalt effects that might have influenced the perception of the overall CAPTCHA figure.

description: We describe a simple way of obtaining horizon entropy using the approach based on the Virasoro algebra and central charge. We show that the Virasoro algebra defined by the Noether currents corresponding to the surface term of gravitational action, for the diffeomorphisms which leave the horizon structure unaltered, has a central extension that directly leads to the horizon entropy. In this approach there are no ambiguities in the calculation of the central charge. We explain why this approach is physically well motivated and could provide greater insight into the nature of horizon entropy.

description: Urban stormwater runoff is acknowledged to be the primary source of microbial contamination in stormwater ponds. The microbial quality would constrain the reuse of stormwater in these bodies (e.g., for irrigation) to reduce potable water demands. In the context of microbial quality, less is known about its spatial distribution and temporal variation, and their influential factors. In this study, Escherichia-coli (E.coli) and fecal coliform (FC), which are commonly used Fecal Indicator Bacteria (FIB), were monitored and the microbial source tracking was conducted in the Inverness, McCall Lake, and Country Hills stormwater ponds situated in the City of Calgary, Alberta. These ponds have been considered as the potential sites for stormwater reuse. The statistical analysis was conducted to analyze the monitoring data aiming to investigate the spatial and temporal variations of the microbial quality. The results showed that the FIBs were heterogeneously distributed in each pond. Overall, the FIB concentrations at the sampling locations in the vicinity of outfalls draining into the ponds were significantly or relatively higher than those in the vicinity of inlets draining out of the ponds. The results also implied that stormwater drained from the subcatchments with a higher percentage of commercial land use was more contaminated than those with primary residential land use. Rain events were found to elevate the FIB concentrations in general, while the antecedent rainfall was also detected to affect the FIB concentrations at several sampling sites. Whereas increased levels of FIB concentrations were also observed during dry periods or following very light rainfalls, especially in McCall Lake Stormwater Pond. This might be ascribed to the human sewage contamination, as it was found to be another main source of microbial pollution, especially in McCall Lake Stormwater Pond, followed by seagull feces in the microbial source tracking. Moreover, the temporal variations of FIB concentrations were observed from the Inverness Stormwater Pond, whose land use was largely changed due to increased residential development during the monitoring period. The results, however, suggested that the temporal variation might be more associated with the meteorological conditions (rainfall and/or temperature) than the residential development.

Four themes arose from the autistic viewpoint: (1) Holistic perspective of work readiness; (2) Work readiness is not a static concept; (3) Work readiness consists of position-dependent skills; and (4) Increasing work readiness for autistic individuals. Additionally, four themes resulted from the employer viewpoint: (1) Work readiness includes a holistic view of the person; (2) Work readiness consists of the same standards with adjustments; (3) Work readiness consists of position-dependent skills; and (4) Improving work readiness for autistic individuals. The present study has implications for stakeholder viewpoints on work readiness, informing improvements to work readiness programs, and improving employment outcomes for autistic individuals. Implications for practice and future research directions are discussed.

description: We propose an approach allowing the computation of currents and their correlations in interacting multiterminal mesoscopic systems involving quantum dots coupled to normal and/or superconducting leads. The formalism relies on the expression of branching currents and noise crossed correlations in terms of one- and two-particle Green's functions for the dots electrons, which are then evaluated self-consistently within a conserving approximation. We then apply this to the Cooper-pair beam-splitter setup recently proposed [L. Hofstetter et al. Nature (London) 461 960 (2009); Phys. Rev. Lett. 107 136801 (2011); L. G. Herrmann et al. Phys. Rev. Lett. 104 026801 (2010)], which we model as a double quantum dot with weak interactions, connected to a superconducting lead and two normal ones. Our method not only enables us to take into account a local repulsive interaction on the dots, but also to study its competition with the direct tunneling between dots. Our results suggest that even a weak Coulomb repulsion tends to favor positive current cross correlations in the antisymmetric regime (where the dots have opposite energies with respect to the superconducting chemical potential).

description: The decline of the Seljuk Empire in the twelfth century C.E. and Seljuk Sultan Ahmad Sanjar’s defeat by the hands of the Qara Khitai and the Khwarazmian state, led to the loss of the Seljuk’s eastern territories. These eastern territories became split between the Qara Khitai, The Khwarazmain Empire, and The Ghurid Sultanate. Building upon the work of his late father Khwarazmshah Tekesh, Khwarazmshah Muhammad was able to defeat both the Ghurids and the Qara Khitai by 1210. At this same time there was a new rising power to the east: The Mongol Empire, led by Chinggis Khan. In 1217, a Khwarazmian governor executed a Mongol ambassador at Otrar. An act that resulted in war. The success and westward expansion of the Mongol Empire is well known. But at this time between 1217 and 1221, their victory was not a guaranteed outcome as the Khwarazmian empire had greater manpower and experience fighting nomadic empires such as the Qara Khitai. In the historiography of this period, especially in the English language, little to no time or attention is given to analyzing this conflict that was a pivotal point in Mongol history and the broader history of the region. Historians generally default to the primary source argument of Hubris as the reason for why Khwarazm fell and dedicate no more than a few pages to this conflict at best. So, what caused the downfall of the Khwarazmian empire? In short, the answer was that it fell as a consequence of military failings (conquest by Mongols), exacerbated by political and bureaucratic (organizational) failures. Militarily, the strategy of city defense and the division of manpower for that strategy meant that the Mongols rarely faced a Khwarazmian army in the field. Politically, the Khwarazmian Empire was the by-product of both internal and external issues. Internally, these issues were the unreliable subordinate lords and the queen regent Terken Khatun, whose power conflicted with the Khwarazmshah himself. Externally, Khwarazm was under constant pressure from its hostile neighbors, who often sought ways of undermining Khwarazm’s stability. Such matters could not be explained by hubris alone.
Vanishing Thermal Mass in the Strongly Coupled QCD/QED medium

description: In this paper we perform a nonperturbative analysis of a thermal quasifermion in thermal QCD/QED by studying its self-energy function through the Dyson-Schwinger equation with the hard-thermal-loop resummed improved ladder kernel. Our analysis reveals several interesting results, some of which may force us to change the image of the thermal quasifermion: (1) The thermal mass of a quasifermion begins to decrease as the coupling gets stronger and finally disappears in the strong coupling region,(2) the imaginary part of the chiral invariant mass function (i.e., the decay width of the quasifermion) persists to have $O(g^2 T \log (1/g))$ behavior. Present results suggest that in the recently produced strongly coupled quark-gluon-plasma, the thermal mass of a quasifermion should vanish. We also briefly comment on evidence of the existence of a massless, or an ultrasoft mode.

description: We present a novel method to perform quantum state tomography for many-particle systems which are particularly suitable for estimating states in lattice systems such as of ultra-cold atoms in optical lattices. We show that the need for measuring a tomographically complete set of observables can be overcome by letting the state evolve under some suitably chosen random circuits followed by the measurement of a single observable. We generalize known results about the approximation of unitary 2-designs, i.e., certain classes of random unitary matrices, by random quantum circuits and connect our findings to the theory of quantum compressed sensing. We show that for ultra-cold atoms in optical lattices established techniques like optical super-lattices, laser speckles, and time-of-flight measurements are sufficient to perform fully certified, assumption-free tomography. Combining our approach with tensor network methods - in particular the theory of matrix-product states - we identify situations where the effort of reconstruction is even constant in the number of lattice sites, allowing in principle to perform tomography on large-scale systems readily available in present experiments.

description: A new example of a saturated Kochen-Specker (KS) type configuration of 64 rays in 8-dimensional space (the Hilbert space of a triple of qubits) is constructed. It is proven that this configuration has a tropical dimension 6 and that it contains a critical subconfiguration of 36 rays. A natural multicolored generalisation of the Kochen-Specker theory is given based on a concept of an entropy of a saturated configuration of rays.

description: In recent years, family YouTube channels have gained popularity, and have raised a number of concerns about children, privacy, and exploitation in the context of sharenting and microcelebrity. Sometimes, viewers’ concern about children’s well-being leads to backlash against microcelebrity parents. In response, these parents often release apology videos on YouTube in order to repair their image and maintain good standing with their audience. My thesis examined such apology videos to investigate how microcelebrity parents employ children’s privacy in order to repair their image and further their brand according to the ethos of calibrated amateurism. I performed a textual and visual analysis on four YouTube apology videos from two family channels, Myka Stauffer and DaddyOFive, that found themselves at odds with their viewers when their sharenting practices resulted in significant controversy. I employed both Benoit’s (2014c) theory of image repair and Abidin’s (2017) notion of calibrated amateurism as my theoretical perspectives to identify some key conventions of apology videos. In accounting for the comments on these videos, I further analyzed how apology videos are received when microcelebrity parents deploy notions of their children’s privacy as part of this image repair. I found that the conventions of these family apology videos manifested calibrated amateurism while the microcelebrity parents used the language of privacy to protect their brand image in a way that contradicted some of their previous sharenting practices.
