    Additive partially linear model for pooled biomonitoring data

    No full text
    Human biomonitoring involves monitoring human health by measuring the accumulation of harmful chemicals, typically in specimens like blood samples. The high cost of chemical analysis has led researchers to adopt a cost-effective approach. This approach physically combines specimens and subsequently analyzes the concentration of toxic substances within the merged pools. Consequently, there arises a need for innovative regression techniques to effectively interpret these aggregated measurements. To address this need, a new regression framework is proposed by extending the additive partially linear model (APLM) to accommodate the pooling context. The APLM is well-known for its versatility in capturing the complex association between outcomes and covariates, which is particularly valuable in assessing the complex interplay between chemical bioaccumulation and potential risk factors. Consistent estimators of the APLM are obtained through an iterative process that disaggregates information from the pooled observations. The performance is evaluated through simulations and an environmental health study focused on brominated flame retardants using data from the National Health and Nutrition Examination Survey

    Instructional Use and Teacher Perceived Effectiveness of Evidenced-Based Reading Comprehension Interventions for Learners with Autism Spectrum Disorder

    No full text
    Effective reading comprehension skills are fundamental in helping children successfully access curriculum area content. Without possessing these critical skills, the next stage of reading becomes increasingly difficult and is likely to impede overall learning. While research in this area is sparse, reading comprehension difficulties are common among autistic students. The purpose of this study was to investigate teachers\u27 perceived effectiveness of evidence-based reading comprehension interventions for autistic learners through an examination of teacher preparedness, current instructional use, and administrative access and support. Results indicated educators find read aloud to be the most effective strategy for this population, while cooperative learning was determined to be the least effective and used overall. Administrative support and professional development opportunities is an ongoing challenge for educators. Future research should consider the use of qualitative methods to gain insight into teacher’s perception, as well as implementing research practice partnerships for intervention development and educator support

    A seismological method for estimating the long-period transition period TL in the seismic building code

    No full text
    Many changes have been made to the design response spectrum used in the ASCE 7 Standard in recent years. One parameter that has not been investigated or revisited since its first appearance in FEMA 450-1/2003 is the long-period transition period parameter, TL. The long-period transition period parameter was introduced and defined as the corner period that marks the transition from the constant velocity to the constant displacement segments of the design response spectrum. The long-period transition period parameter is primarily important for long-period structures such as high-rise buildings and bridges. The most current estimation of TL used in engineering design standards is loosely based on a correlation between modal magnitude Mw and TL that does not account for stress drop Δσ or the crustal velocity in the source region β. This study aims to include both Δσ and β in its estimation of TL. Modal magnitude is obtained from disaggregation data from the 2018 National Seismic Hazard Model (NSHM) for the conterminous United States (CONUS) and from the 2021 NSHM for Hawaii (HI). The parameter β is determined from previous literature. Then, inversion of ground motion models for Central and Eastern United States (CEUS) is used to determine Δσ for CEUS events, and published information is used to determine Δσ for Western United States (WUS) events and HI events. Then, the definition of the corner period is used to determine TL. The results yield a generally more conservative (or longer) estimation of TL than the estimation that is currently used in engineering design standards

    Flourishing through The Spectrum: Toward an affective-oriented composite pedagogical model?

    No full text
    The concept of models-based practice has arguably provided the field of sport pedagogy with the means, lens, and tools with which to start to transform the discipline into a more desirable, equitable, and purposeful space. Despite this, there remains a need to experiment with this concept further in non-traditional ways and to continue to construct new pedagogical models meant to serve youth in ever-changing pluralist societies. The purpose of this paper, therefore, was to outline an affective-oriented composite pedagogical model, titled The Spectrum Model, by drawing from Mosston and Ashworth\u27s theory for the spectrum of teaching and learning and neo-Aristotelian virtue ethics. To achieve this goal, I begin by highlighting the need for studying the synergy between the spectrum and models-based practice more closely. Thereafter, I attempt to clarify spectrum theory, virtue ethics, and the concept of models-based practice. Finally, I conclude by presenting two broad main ideas, three critical elements, six intended learning aspirations, and a series of suggested pedagogies acting to inform the proposed Spectrum Model. This model has the potential to influence how practitioners and scholars understand the spectrum of teaching and learning within the broader notion of models-based practice. The application and integration of moral philosophy into a well-established pedagogical framework might also help pedagogues of all kinds to envision how they could help youth to obtain a fully flourishing lifestyle through their teaching

    Identifying Factors Influencing Recreational Travel during the COVID-19 Pandemic

    No full text
    This study aims to identify the psychological constructs that are antecedents to people\u27s intention to travel to a tourist destination during the COVID-19 pandemic using the extended theory of planned behavior (ETPB) and necessary condition analysis (NCA). Online survey responses collected from 1,259 participants in the United States in May-June 2021 are used for the study. We find a moderating effect of public trust towards the government on the relationship between travel concerns and intentions. Results suggest that certain levels of public trust, subjective norm, perceived benefit of travel, perceived behavioral control, and perceived knowledge of the pandemic are necessary to manifest travel intentions. We uncover that providing travel incentives and better dissemination of the pandemic-related information can potentially encourage people to regain their original travel intention that was lost due to the pandemic. Furthermore, the bottlenecks obtained using NCA show that travel intentions are more easily manifested by perceived knowledge of the pandemic versus others. This study demonstrates the application of NCA, which can be further extended to make policy-level decisions for transportation systems

    The language of wine reviews

    No full text
    Expert wine reviewers have a niche skill set, with a particular lexicon, that facilitates their evaluation of wines. Novice consumers may find wine reviews intimidating and confusing. In this paper, we use a dataset of nearly 130,000 reviews from expert reviewers at Wine Enthusiast to explore the lexical dimension of wine reviews and determine to what extent reviewers systematically use language differently across various wine price points. Trends reveal that the information needed to make informed wine purchases are provided through the language of wine reviews. Our analysis shows that wine selection does not require a technical understanding of the wine-specific vocabulary of wine experts. We present a review of the literature on wine reviews and form four hypotheses under the theoretical framework of Kahneman’s two systems of thought—suggesting the linguistic properties of wine reviews reveal the price of wine. We examine how the lexical categories; emotional and logical linguistic content; social; and somatic experiences used in wine reviews relate to price. We then suggest the applicability of this analysis to other commodity domains in future research
