description:
BACKGROUND: HIV self-testing (HIVST) has been rapidly scaled up and additional strategies further expand testing uptake. Secondary distribution involves people (defined as "indexes") applying for multiple kits and subsequently sharing them with people (defined as "alters") in their social networks. However, identifying key influencers is difficult. OBJECTIVE: This study aimed to develop an innovative ensemble machine learning approach to identify key influencers among Chinese men who have sex with men (MSM) for secondary distribution of HIVST kits. METHODS: We defined three types of key influencers: (1) key distributors who can distribute more kits, (2) key promoters who can contribute to finding first-time testing alters, and (3) key detectors who can help to find positive alters. Four machine learning models (logistic regression, support vector machine, decision tree, and random forest) were trained to identify key influencers. An ensemble learning algorithm was adopted to combine these 4 models. For comparison with our machine learning models, self-evaluated leadership scales were used as the human identification approach. Four metrics for performance evaluation, including accuracy, precision, recall, and F1-score, were used to evaluate the machine learning models and the human identification approach. Simulation experiments were carried out to validate our approach. RESULTS: We included 309 indexes (our sample size) who were eligible and applied for multiple test kits; they distributed these kits to 269 alters. We compared the performance of the machine learning classification and ensemble learning models with that of the human identification approach based on leadership self-evaluated scales in terms of the 2 nearest cutoffs. Our approach outperformed human identification (based on the cutoff of the self-reported scales), exceeding by an average accuracy of 11.0%, could distribute 18.2% (95% CI 9.9%-26.5%) more kits, and find 13.6% (95% CI 1.9%-25.3%) more first-time testing alters and 12.0% (95% CI -14.7% to 38.7%) more positive-testing alters. Our approach could also increase the simulated intervention's efficiency by 17.7% (95% CI -3.5% to 38.8%) compared to that of human identification. CONCLUSIONS: We built machine learning models to identify key influencers among Chinese MSM who were more likely to engage in secondary distribution of HIVST kits.

description: In this paper, we propose fixed-order set-valued (in the form of l2-norm hyperballs) observers for some classes of nonlinear bounded-error dynamical systems with unknown input signals that simultaneously find bounded hyperballs of states and unknown inputs that include the true states and inputs. Necessary and sufficient conditions in the form of Linear Matrix Inequalities (LMIs) for the stability (in the sense of quadratic stability) of the proposed observers are derived for ($\mathcal{M},γ$)- Quadratically Constrained (($\mathcal{M},γ$)-QC) systems, which includes several classes of nonlinear systems: (I) Lipschitz continuous, (II) ($\mathcal{A},γ$)-QC* and (III) Linear Parameter-Varying (LPV) systems. This new quadratic constraint property is at least as general as the incremental quadratic constraint property for nonlinear systems and is proven in the paper to embody a broad range of nonlinearities. In addition, we design the optimal $\mathcal{H}_{\infty}$ observer among those that satisfy the quadratic stability conditions and show that the design results in Uniformly Bounded-Input Bounded-State (UBIBS) estimate radii/error dynamics and uniformly bounded sequences of the estimate radii. Furthermore, we provide closed-form upper bound sequences for the estimate radii and sufficient condition for their convergence to steady state. Finally, the effectiveness of the proposed set-valued observers is demonstrated through illustrative examples, where we compare the performance of our observers with some existing observers.

description:
Despite recent methodology advancements in clinical natural language processing (NLP), the adoption of clinical NLP models within the translational research community remains hindered by process heterogeneity and human factor variations. Concurrently, these factors also dramatically increase the difficulty in developing NLP models in multi-site settings, which is necessary for algorithm robustness and generalizability. Here, we reported on our experience developing an NLP solution for Coronavirus Disease 2019 (COVID-19) signs and symptom extraction in an open NLP framework from a subset of sites participating in the National COVID Cohort (N3C). We then empirically highlight the benefits of multi-site data for both symbolic and statistical methods, as well as highlight the need for federated annotation and evaluation to resolve several pitfalls encountered in the course of these efforts.

description: >Virtual Organizations<, >Virtual Enterprises< und >Smart Organizations< werden immer häufiger als zukünftige Geschäftsform für des Bauwesens und insbesondere der Bauplanung gesehen. Ziel dieser Organisationsformen ist es, eine temporäre geschäftliche Zusammenarbeit zur Erschließung neuer Geschäftsfelder aufzubauen, ausgehend von einer strategischen Geschäftsverbindung. Insbesondere für kleine Planungsbüros können sich hieraus Möglichkeiten zur Durchführung größerer Projekte eröffnen, indem notwendige Ressourcen, wie z.B. Fachingenieure, jeder Zeit flexibel integriert werden können. Neben dem Auftreten als Projektmanager besteht für die Planungsbüros auch die Möglichkeit Spezialwissen sowie nicht benötigte Ressourcen in andere Projekte zu integrieren. Ziel ist es dabei, eine kontinuierliche Auslastung der Mitarbeiter sicherzustellen. Durch die Nutzung einer geeigneten und allgemein zugänglichen IT-Infrastruktur über das Internet können neue Partner ohne großen Aufwand in ein Projekt aufgenommen werden indem diesen Zugriffe auf alle notwendigen Projektinformationen gegeben wird. Mit der Bereitstellung passender IT-Werkzeuge für das Projektmanagement, Datenmanagement und Vertragsmanagement wird eine effektive Projektbearbeitung gewährleistet. In diesem Beitrag werden die konzeptionellen Grundlagen virtueller Organisation genauer betrachtet und deren Anwendbarkeit auf virtuelle Planungsteams im Bauwesen untersucht. Anschließend wird, aufbauend auf diese Erkenntnisse, der Aufbau und die Komponenten einer Softwareumgebung zur Unterstützung des virtuellen Planungsteams erörtert. Zum Schluss erfolgt eine Darstellung des durch das BmBF geförderte Projekt iCSS.

description: To determine the prevalence of ophthalmological findings suggesting an ocular cause for headache or occult neurological disease, among children with headache. Retrospective cross-sectional study on children with headache at a tertiary outpatient ophthalmology clinic. All children underwent sensorimotor, anterior segment, and dilated fundoscopic examinations, with or without cycloplegic refraction. Prevalence of one or more new findings of ocular or occult neurological cause of headache, including glaucoma, uveitis, optic nerve elevation, or possible asthenopia from strabismus or refractive issues. Headache characteristics and associated symptoms were evaluated as risk factors for ocular findings. Among 1,878 children with headache (mean age 10 yrs, range 2–18), 492 (26.1%, 95% CI 24.3–28.2%) children had one or more new ocular findings that could cause headache or indicate intracranial disease: refractive issues (342, 18.2%), strabismus (83, 4.4%), optic nerve elevation (51, 2.7%; 26 with papilledema, 25 with pseudopapilledema), uveitis (6, 0.3%), and glaucoma (2, 0.1%). Shorter headache duration was associated with ocular findings (p = .047), but headache frequency, photophobia, nausea/vomiting, and visual changes were not. In univariable analysis, visual changes (p ≤ .001), nausea/vomiting (p ≤ .002), and morning headache (p = .02) were associated with optic nerve elevation. An ophthalmologic examination including cycloplegic refraction is indicated in children with headache, as one-quarter have a treatable ocular condition, which may be related to the headache, or sign of intracranial pathology. While nausea, visual changes, or morning headache should raise concern, coincident visual, ocular, or systemic symptoms are not reliable predictors of discovering ocular pathology in a child with headache.

description: We give a crystal-theoretic proof that nonsymmetric Macdonald polynomials specialized to $t=0$ are affine Demazure characters. We explicitly construct an affine Demazure crystal on semistandard key tabloids such that removing the affine edges recovers the finite Demazure crystals constructed earlier by the authors. We also realize the filtration on highest weight modules by Demazure modules by defining explicit embedding operators which, at the level of characters, parallels the recursion operators of Knop and Sahi for specialized nonsymmetric Macdonald polynomials. Thus we prove combinatorially in type A that every affine Demazure module admits a finite Demazure flag.

description: Today´s procedures for the awarding of public construction performance contracts are mainly paper-based. Although the usage of electronic means is permitted in the VOB, the regulations are not sufficient yet. Especially software agents within the AEC-bidding process were not considered at all. The acceptance of an agent-based virtual marketplace for AEC-bidding depends on a reliable and trustworthy public key infrastructure according to the (German) digital signature act. Only if confidentiality, integrity, non-repudiation, and authentication are provided reliably, users will assign sensitive business processes like public tendering procedures to software agents. The development of a secure agent-based virtual marketplace for AEC-bidding according to legal regulations is an entirely new approach from a technical as well as from a legal point of view. The objective of this research project is the development of intelligent software-agents which are able to legally call for bids, to calculate proposals, and to award the successful bidder.

Background: Little is known regarding the mental health impact of having a significant person (family member and/or close friend) with COVID-19 of different severity. Methods: The study included five prospective cohorts from four countries (Iceland, Norway, Sweden, and the UK) with self-reported data on COVID-19 and symptoms of depression and anxiety during March 2020-March 2022. We calculated prevalence ratios (PR) of depression and anxiety in relation to having a significant person with COVID-19 and performed a longitudinal analysis in the Swedish cohort to describe temporal patterns. Findings: 162,237 and 168,783 individuals were included in the analysis of depression and anxiety, respectively, of whom 24,718 and 27,003 reported a significant person with COVID-19. Overall, the PR was 1.07 (95% CI: 1.05-1.10) for depression and 1.08 (95% CI: 1.03-1.13) for anxiety in relation to having a significant person with COVID-19. The respective PRs for depression and anxiety were 1.15 (95% CI: 1.08-1.23) and 1.24 (95% CI: 1.14-1.34) if the patient was hospitalized, 1.42 (95% CI: 1.27-1.57) and 1.45 (95% CI: 1.31-1.60) if the patient was ICU-admitted, and 1.34 (95% CI: 1.22-1.46) and 1.36 (95% CI: 1.22-1.51) if the patient died. Individuals with a significant person with hospitalized, ICU-admitted, or fatal COVID-19 showed elevated prevalence of depression and anxiety during the entire year after the COVID-19 diagnosis. Interpretation: Family members and close friends of critically ill COVID-19 patients show persistently elevated prevalence of depressive and anxiety symptoms. Funding: This study was primarily supported by NordForsk (COVIDMENT, 105668) and Horizon 2020 (CoMorMent, 847776).

description: Poor eye-health knowledge and health literacy are pervasive, contributing to worse outcomes. This study aims to examine short- and long-term eye-health knowledge retention following eye-health education interventions in adults. Vision Detroit was an outreach vision screening program that integrated a 5-Point Teaching Intervention (5PTI), at a Southwest Community Center (SW-CC) from 2015–2017. The 5PTI consists of eye-health learning points developed to verbally educate patients. During vision screenings, eye-health knowledge tests were administered before and after 5PTI (Test 1 and Test 2, respectively). In 2016, Community Eye-Health Education Interventions (CHEI) were initiated at the SW-CC. During CHEI, bilingual healthcare students taught voluntary SW-CC members the 5PTI learning points, regardless of participant interest to attend future screenings. CHEI sessions occurred on separate dates prior to vision screening events. Test 1 and Test 2 scores were compared for all participants. Test 1 scores were compared for those who underwent CHEI prior to vision screening (CHEI positive) versus those who did not (CHEI negative). Two-hundred-seventeen adult patients met inclusion criteria, with 75.8% women, 82.6% Hispanic, mean age 50.4 ± 16.2 years, 74.6% had high school or less education, and 49.2% had health insurance. Test 1 to Test 2 scores improved after 5PTI (71.2 ± 26.4% vs. 97.2 ± 9.9%, p < .00001). Forty-eight participants attended CHEI and subsequent vision screening. Test 1 scores were higher among those CHEI positive versus CHEI negative (81.1 ± 2.1% vs. 68.3 ± 3.4%, p = .0027). Simple eye-health education interventions, delivered during vision screenings and via community-based education, can improve eye-health knowledge.

description: Kohnert polynomials are polynomials indexed by unit cell diagrams in the first quadrant defined earlier by the author and Searles that give a common generalization of Schubert polynomials and Demazure characters for the general linear group. Demazure crystals are certain truncations of normal crystals whose characters are Demazure characters. For each diagram satisfying a southwest condition, we construct a Demazure crystal whose character is the Kohnert polynomial for the given diagram, resolving an earlier conjecture of the author and Searles that these polynomials expand nonnegatively into Demazure characters. We give explicit formulas for the expansions with applications including a characterization of those diagrams for which the corresponding Kohnert polynomial is a single Demazure character.

description: If $E$ is a directed graph and $K$ is a field, the Leavitt path algebra $L_K(E)$ of $E$ over $K$ is naturally graded by the group of integers $\mathbb Z.$ We formulate properties of the graph $E$ which are equivalent with $L_K(E)$ being a crossed product, a skew group ring, or a group ring with respect to this natural grading. We state this main result so that the algebra properties of $L_K(E)$ are also characterized in terms of the pre-ordered group properties of the Grothendieck $\mathbb Z$-group of $L_K(E)$. If $E$ has finitely many vertices, we characterize when $L_K(E)$ is strongly graded in terms of the properties of $K_0^Γ(L_K(E)).$ Our proof also provides an alternative to the known proof of the equivalence $L_K(E)$ is strongly graded if and only if $E$ has no sinks for a finite graph $E.$ We also show that, if unital, the algebra $L_K(E)$ is strongly graded and graded unit-regular if and only if $L_K(E)$ is a crossed product. In the process of showing the main result, we obtain conditions on a group $Γ$ and a $Γ$-graded division ring $K$ equivalent with the requirements that a $Γ$-graded matrix ring $R$ over $K$ is strongly graded, a crossed product, a skew group ring, or a group ring. We characterize these properties also in terms of the action of the group $Γ$ on the Grothendieck $Γ$-group $K_0^Γ(R).$

description:
Crude oil pipelines are considered as the lifelines of energy industry. However, accidents of the pipelines can lead to severe public health and environmental concerns, in which greenhouse gas (GHG) emissions, primarily methane, are frequently overlooked. While previous studies examined fugitive emissions in normal operation of crude oil pipelines, emissions resulting from accidents were typically managed separately and were therefore not included in the emission account of oil systems. To bridge this knowledge gap, we employed a bottom-up approach to conducted the first-ever inventory of GHG emissions resulting from crude oil pipeline accidents in the United States at the state level from 1968 to 2020, and leveraged Monte Carlo simulation to estimate the associated uncertainties. Our results reveal that GHG emissions from accidents in gathering pipelines (~720,000 tCO2e) exceed those from transmission pipelines (~290,000 tCO2e), although significantly more accidents have occurred in transmission pipelines (6883 cases) than gathering pipelines (773 cases). Texas accounted for over 40% of total accident-related GHG emissions nationwide. Our study contributes to enhanced accuracy of the GHG account associated with crude oil transport and implementing the data-driven climate mitigation strategies.

description: This paper is concerned with the numerical treatment of quasilinear elliptic partial differential equations. In order to solve the given equation we propose to use a Galerkin approach, but, in contrast to conventional finite element discretizations, we work with trial spaces that, not only exhibit the usual approximation and good localization properties, but, in addition, lead to expansions of any element in the underlying Hilbert spaces in terms in multiscale or wavelet bases with certain stability properties. Specifically, we select as trial spaces a nested sequence of spaces from an appropriate biorthogonal multiscale analysis. This gives rise to a nonlinear discretized system. To overcome the problems of nonlinearity, we make use of the machinery of interpolating wavelets to obtain knot oriented quadrature rules. Finally, Newton's method is applied to approximate the solution in the given ansatz space. The results of some numerical experiments with different biorthogonal systems, confirming the applicability of our scheme, are presented.

Creators: name: Mbonigaba Celestin
Publisher: name: Zenodo
Year: 2018

description: This study explores the role of budgetary slack in managerial decision-making, specifically how companies manipulate budgets by underestimating revenues or overstating expenses to gain strategic flexibility. The research aims to examine the impact of budgetary slack on financial performance, corporate governance, and long-term business sustainability from 2012 to 2016. Using secondary data from industries like financial services, manufacturing, and technology, the study employed descriptive statistics, T-tests, Chi-square tests, and regression analysis. Findings indicate that while budgetary slack provides short-term profitability benefits by allowing firms to manage unforeseen costs, it does not significantly affect overall profitability in a statistically meaningful way. Additionally, companies with strong governance structures are less likely to engage in slack, which highlights the importance of governance in mitigating its adverse effects. The study concludes that while slack can serve as a tool for financial flexibility in volatile markets, its long-term impact on efficiency and transparency is questionable. The research recommends that firms balance the strategic use of budgetary slack with strong governance practices and suggest regulatory bodies enforce clearer guidelines to minimize its misuse.
Efficient post-hazard probabilistic flow analysis of water pipe networks
Creators: name: Kang, Won-Hee
name: Lee, Young-Joo
Publisher: name: The University of British Columbia
Year: 2015

description: This paper proposes a reliability based flow analysis framework for water pipe networks after an earthquake event. The first part of the framework is an automated leakage and breakage modeling of water pipe segments in a network damaged by an earthquake event. The second part is an efficient system-level probabilistic flow analysis based on the Matrix-based System Reliability (MSR) formulation and the branch-and-bound method. It estimates the system-level flow quantities of network pipes and the system damage state probabilities, and significantly reduces the computational costs by sequentially prioritizing the system states according to their likelihoods and by selecting their partial sets. The proposed framework is demonstrated by a water pipe network consisting of 11 pipe segments under an earthquake event, in which the statistical moments and the probability of the water flows of several pipes are estimated based on the proposed framework.

A bijective proof of Kohnert's rule for Schubert polynomials
Creators: name: Assaf, Sami H.
Publisher: name: arXiv

description: Kohnert proposed the first monomial positive formula for Schubert polynomials as the generating polynomial for certain unit cell diagrams obtained from the Rothe diagram of a permutation. Billey, Jockusch and Stanley gave the first proven formula for Schubert polynomials as the generating polynomial for compatible sequences of reduced words of a permutation. In this paper, we give an explicit bijection between these two models, thereby definitively proving Kohnert's rule for Schubert polynomials.

description:
We examined the performance of deep learning models on the classification of thyroid fine-needle aspiration biopsies using microscope images captured in 2 ways: with a high-resolution scanner and with a mobile phone camera. Our training set consisted of images from 964 whole-slide images captured with a high-resolution scanner. Our test set consisted of 100 slides; 20 manually selected regions of interest (ROIs) from each slide were captured in 2 ways as mentioned above. Applying a baseline machine learning algorithm trained on scanner ROIs resulted in performance deterioration when applied to the smartphone ROIs (97.8% area under the receiver operating characteristic curve [AUC], CI = [95.4%, 100.0%] for scanner images vs 89.5% AUC, CI = [82.3%, 96.6%] for mobile images, P = .019). Preliminary analysis via histogram matching showed that the baseline model was overly sensitive to slight color variations in the images (specifically, to color differences between mobile and scanner images). Adding color augmentation during training reduces this sensitivity and narrows the performance gap between mobile and scanner images (97.6% AUC, CI = [95.0%, 100.0%] for scanner images vs 96.0% AUC, CI = [91.8%, 100.0%] for mobile images, P = .309), with both modalities on par with human pathologist performance (95.6% AUC, CI = [91.6%, 99.5%]) for malignancy prediction (P = .398 for pathologist vs scanner and P = .875 for pathologist vs mobile). For indeterminate cases (pathologist-assigned Bethesda category of 3, 4, or 5), color augmentations confer some improvement (88.3% AUC, CI = [73.7%, 100.0%] for the baseline model vs 96.2% AUC, CI = [90.9%, 100.0%] with color augmentations, P = .158). In addition, we found that our model's performance levels off after 15 ROIs, a promising indication that ROI data collection would not be time-consuming for our diagnostic system. Finally, we showed that the model has sensible Bethesda category (TBS) predictions (increasing risk malignancy rate with predicted TBS category, with 0% malignancy for predicted TBS 2 and 100% malignancy for TBS 6).

description: In this paper, we present a resource allocation mechanism for the problem of incentivizing filtering among a finite number of strategic social media platforms. We consider the presence of a strategic government and private knowledge of how misinformation affects the users of the social media platforms. Our proposed mechanism incentivizes social media platforms to filter misleading information efficiently, and thus indirectly prevents the spread of fake news. In particular, we design an economically inspired mechanism that strongly implements all generalized Nash equilibria for efficient filtering of misleading information in the induced game. We show that our mechanism is individually rational, budget balanced, while it has at least one equilibrium. Finally, we show that for quasi-concave utilities and constraints, our mechanism admits a generalized Nash equilibrium and implements a Pareto efficient solution.

description: For the Allen-Cahn equation, it is well known that there is a monotone standing wave joining with the balanced wells of the potential. In this paper we study the existence of traveling wave solutions for the Allen-Cahn equation on an infinite channel. Such traveling wave solutions possess a large number of oscillation and they are obtained with the aid of variational arguments.

description: In this paper, we partly prove a supercongruence conjectured by Z.-W. Sun in 2013. Let $p$ be an odd prime and let $a\in\mathbb{Z}^{+}$. Then if $p\equiv1\pmod3$, we have \begin{align*} \sum_{k=0}^{\lfloor\frac{5}6p^a\rfloor}\frac{\binom{2k}k}{16^k}\equiv\left(\frac{3}{p^a}\right)\pmod{p^2}, \end{align*} where $\left(\frac{\cdot}{\cdot}\right)$ is the Jacobi symbol.

description: Die Situation in der Immobilienwirtschaft hat sich in den letzten Jahren grundlegend verändert. Die Neubauaktivitäten in ganz Deutschland sind deutlich zurückgegangen. Das Bauen im Bestand mit den Tätigkeitsfeldern der Renovierung, Modernisierung und Instandsetzung rückt daher in den Mittelpunkt der Aktivitäten. Laut Bundesarbeitskreis Altbauerneuerungen werden im nächsten Jahr 74 Prozent des gesamten Bauvolumens auf die Modernisierung von alten Häusern entfallen, der Anteil der Neubaumaßnahmen geht auf 26 Prozent zurück. Dies gilt nicht nur für Wohn-, sondern auch für Gewerbeimmobilien. Die anhaltende Rezession und die Entzauberung der New Economy ziehen in diesem Bereich Leerstände und fallende Mieten nach sich. Auch die Wohnungswirtschaft hat vor allem in den neuen Ländern mit Leerständen zu kämpfen. Diese Tatsache zwingt Immobilienbetreiber zunehmend dazu, Methoden zu ergreifen und Werkzeuge einzusetzen, die die Effizienz im eigenen Unternehmen steigern. Die Aufgabenstellung lautet: Mehr Sanierungsprojekte in der selben Zeit abwickeln. Dies setzt eine prozessorientierte Vorgehensweise und unterstützende Werkzeuge voraus. Mit dem baucommunicator wurde ein Werkzeug entwickelt, dass es dem Gebäudemanager ermöglicht, bei der Abwicklung von Bau- und Sanierungsmaßnahmen im Aufgabenfeld der Koordination dieser Aufgabenstellung zu entsprechen. Die Kernfunktionen der Software sind das Termin-, Kosten und Qualitätsmanagement bei der Abwicklung von Bauprozessen. Die unternehmensübergreifende Konzeption erlaubt sowohl dem Auftraggeber, wie auch den ausführenden Betrieben den Zugriff auf die zentral abgelegten Projektinformationen. Die Workflow-Funktionalität des baucommunicator führt zu einer Reduktion der Prozessaktivitäten. Dadurch werden Kosten eingespart und die Ausführungsqualität gesteigert.

description:
Purpose To explore experiences of sheltering in place and accessing treatment during the initial stages of the COVID-19 pandemic among survivors with cancer receiving tyrosine kinase inhibitor (TKI) therapy. Methods Participants from two pilot studies evaluating TKI therapy use in the Southeastern United States during the start of the COVID-19 pandemic (March 2020) were interviewed. Identical interview guides were used across both studies to assess participants’ experiences accessing cancer treatment, sheltering in place, and coping during the COVID-19 pandemic. Digitally recorded sessions were transcribed professionally and checked for accuracy. Descriptive statistics were used to summarize participant sociodemographics, and a six-step thematic approach was used to analyze interview data and identify salient themes. Dedoose qualitative research software was used to manage and organize qualitative codes, themes, and memos. Results Participants (n = 15) ranged from 43 to 84 years of age, and were mostly female (53.3%), married (60%), and survivors with hematologic malignancies (86.7%). The research team identified five salient themes: Participants followed pandemic guidelines, Variable impact on well-being, Common feelings of fear, anxiety and anger, No barriers to accessing therapy and medical care, and Faith and God as powerful forces for coping. Conclusions The conclusions of the study provide several implications for survivorship programs or clinics for supporting survivors who are taking chronic TKI therapy during COVID-19, including enhancement of current psychosocial support efforts for cancer survivors or development of new programs tailored to the unique needs of a survivor during a pandemic, such as focused coping strategies, modified physical activity programs, family/professional role changes, and access to safe public spaces.
