Purpose The purpose of this study was to explore the perceptions of special education practitioners (i.e., speech-language pathologists, special educators, para-educators, and other related service providers) on their role as communication partners after participation in the Social Communication and Engagement Triad (Buckley et al., 2015 ) yearlong professional learning program. Method A qualitative approach using interviews and purposeful sampling was used. A total of 22 participants who completed participation in either Year 1 or Year 2 of the program were interviewed. Participants were speech-language pathologists, special educators, para-educators, and other related service providers. Using a grounded theory approach (Glaser & Strauss, 1967 ) to data analysis, open, axial, and selective coding procedures were followed. Results Three themes emerged from the data analysis and included engagement as the goal, role as a communication partner, and importance of collaboration. Conclusions Findings supported the notion that educators see the value of an integrative approach to service delivery, supporting students' social communication and engagement across the school day but also recognizing the challenges they face in making this a reality.

Abstract School speech-language pathologists and districts frequently need guidance regarding how the legal provisions of special education affect the needs of children with dysphagia. This article reviews key principles of special education that guide eligibility determination and provision of services to all children. In the eligibility process, the school team would determine if the child's disability has an adverse effect on his/her education program and if the child needed special education (specially designed instruction) and related services. Dysphagia services would be considered a related service, a health service needed for the child to benefit from specially designed instruction. The article concludes with recommendations for practice that stem from a review of due process hearings and court cases for children with disabilities that include swallowing.

Abstract A review of the prevalent degradation mechanisms in Lithium ion batteries is presented. Degradation and eventual failure in lithium-ion batteries can occur for a variety of dfferent reasons. Degradation in storage occurs primarily due to the self-discharge mechanisms, and is accelerated during storage at elevated temperatures. The degradation and failure during use conditions is generally accelerated due to the transient power requirements, the high frequency of charge/discharge cycles and differences between the state-of-charge and the depth of discharge influence the degradation and failure process. A step-by-step methodology for conducting a failure analysis of Lithion batteries is presented. The failure analysis methodology is illustrated using a decision-tree approach, which enables the user to evaluate and select the most appropriate techniques based on the observed battery characteristics. The techniques start with non-destructive and non-intrusive steps and shift to those that are more destructive and analytical in nature as information about the battery state is gained through a set of measurements and experimental techniques.

While assistive technology is often suggested as a way to increase, maintain, or improve functional ability for individuals with disabilities within physical activity (PA) settings, cost and availability of such items are often noted as barriers. In recent years, 3D printing has become available to the general public through the adoption of 3D printers in schools, libraries, and universities. Through individual design and rapid prototyping, 3D printing can support physical educators in accommodating student need for assistive technology through a multitude of modification possibilities. This article will highlight the capacity for 3D printed assistive technology within educational settings, and will illustrate how teachers, APE specialists, and other related service personnel can utilize this technology to support student success in PE and PA settings. This article will also assist practitioners with locating, uploading, and utilizing existing collections of 3D assistive technology models from open-source websites, such as Thingiverse.

AbstractMulti-unit firms have productivity advantages over competitors because of their use of a non-rival asset—firm-specific knowledge—in several units. Using knowledge-intensive services leads to economies of scope in production by multi-unit firms. Such headquarter are usually supplied by parent companies and serve to link different firm units. Headquarter services are difficult to quantify in statistics or surveys, except when they cross-borders and the exchange of services between MNEs and their offshore subsidiaries becomes apparent. This study therefore focuses on IT service imports to explain productivity differences among foreign affiliates of multinational firms in Germany. The authors base the analysis on the population of foreign multinational firms active in Germany and analyze what effect the import of IT services has on their productivity. They find that IT headquarter service flows have significant impacts on foreign affiliates’ productivity in general and US affiliates in particular. As the average IT-service flows (per firm and partner) from parent countries are significantly higher for US affiliates than non-US affiliates, they conclude that the import of IT services from the parent-company is a source of the productivity advantages of US affiliates in Germany.

Accurate estimation of the degree of battery aging is essential to ensure safe operation of electric vehicles. In this paper, using real-world vehicles and their operational data, a battery aging estimation method is proposed based on a dual-polarization equivalent circuit (DPEC) model and multiple data-driven models. The DPEC model and the forgetting factor recursive least-squares method are used to determine the battery system’s ohmic internal resistance, with outliers being filtered using boxplots. Furthermore, eight common data-driven models are used to describe the relationship between battery degradation and the factors influencing this degradation, and these models are analyzed and compared in terms of both estimation accuracy and computational requirements. The results show that the gradient descent tree regression, XGBoost regression, and light GBM regression models are more accurate than the other methods, with root mean square errors of less than 6.9 mΩ. The AdaBoost and random forest regression models are regarded as alternative groups because of their relative instability. The linear regression, support vector machine regression, and k-nearest neighbor regression models are not recommended because of poor accuracy or excessively high computational requirements. This work can serve as a reference for subsequent battery degradation studies based on real-time operational data.
