While the medical community continues to recognize the contributions of disordered sleep to the burden of Prader-Willi syndrome (PWS), the medical literature lacks characterization of the patient burden of sleep disorders by people living with PWS and their caregivers. We developed and fielded a 72-question survey to the online PWS community, to query caregivers about their experiences with sleep symptoms. Respondents for all age groups reported sleep-disordered breathing (40 %), cataplexy-like symptoms (28.4 %), and insomnia (43.5 %). The presentation of cataplexy-like symptoms tended to change as children aged, presenting initially (ages 0–4 years) as head bobbing while eating, then transitioning to knee buckling between the ages of 5–12 years. Finally, loss of generalized tone associated with extreme emotions became more common in the teenage years. Frequent screening for potentially treatable sleep disorders should be considered the standard of care for individuals with PWS.

This chapter shares a blend of evidence-based theory and reflexive, narrative first-person experiences in support of simultaneously adopting a formal position of student while serving as a leader and teacher in systems of higher education. The article does not argue for any one particular approach to intentionally adopting and maintaining an identity and status as student while also leading in teaching and administrative roles. Instead, the breadth of possible ways to simultaneously adopt a student identity while teaching and leading is highlighted and an ongoing state of reflexive and iterative student status is encouraged. The focus is on spaces in which the intersection of dual identities can further support and strengthen individual experiences as student, leader, and teacher within educational institutions.

Abstract This project's goal is to improve critical thinking in undergraduate engineering students through a new educational intervention aimed at enhancing ethics and professional responsibility. Developing an understanding of how engineering students perceive the broader impacts of their chosen profession, especially as articulated through the lens of ethics and professional responsibility, is an important first step in addressing professional formation. The current model of engineering education, focused primarily on technical proficiency, leaves little room for the structured and integrated exploration of these broader impacts. The intervention that was evaluated in this study involved student-group discussions that were centered around professionally produced narratives in an audio format. Students were required to listen to the narrative, respond to focus questions, engage with their peers' responses to the questions and then reflect on the experience. After completing this assignment for three narratives, students (N=45) participated in a separate discussion involving the ethical issues and broader impacts of engineering work that they encountered while working on their senior design projects. The same exercise was exercise was completed by a comparison group (N=49) that was not exposed to the intervention. Our results indicate that exposure to the critical narrative intervention did enhance students' abilities to identify ethical issues and broader impacts of engineering work (p<.05).

In this proceeding, we present polarization data of sidebands emitted from strongly driven quasiparticles, demonstrate the dependence of these data on various parameters of the external driving field, and describe the data using an analytical expression, dependent on driving field parameters and the effective Hamiltonian of the system. We propose using this method on spin-momentum locked systems, such as altermagnets, to observe and reconstruct sidebands which are influenced by the topology of individual bands.

Global food security and health awareness have increased, thus driving demand for organic food. Blitar, one of the duck farming centers on Java Island, has much potential to develop organic farming. However, consumer attitudes and product acceptance of organic farming must be analyzed to develop organic farming. Therefore, this study aimed to identify the factors that determine consumer attitudes and preferences in buying processed organic duck meat. This study used 39 respondents who live in Blitar. This study used the Fishbein method to assess consumers’ beliefs and important levels of attributes of processed duck. The results showed that 74% of respondents were willing to buy organic processed duck meat. Meanwhile, the most important attributes of processed duck products decided by consumers were taste (3,74), packaging (3,62), and aroma (3,61). The three major belief values for organic processed duck products were health factor (3,61), label (3,58), and taste (3,38), while for non-organic processed duck were label (3,72), packaging (3,62), and taste (3,59).

In our endeavor to find antibacterial from marine bacteria, we screened the microbiota from a Lithistid sponge, collected from Seribu Island, Jakarta. One of the promising strains was K 2.4.2. Identification of the strain using 16S rRNA Sanger sequencing resulted a sequence similarity of 100% to Bacillus tequilensis. Response surface methodology was applied to optimize the culture conditions for enhancing antibacterial activity of the strain. The optimization was carried out using Box-Behnken design experiment to determine the optimum carbon and nitrogen sources in order to produce maximum antibacterial activity. The optimum media with high antibacterial activity was marine broth with the addition of carbon and nitrogen concentration source of sucrose 2.15 % and peptone 1.08%, respectively. In addition, the optimum temperature was 31.18oC. The antibacterial activity response was predicted using a statistical model and compared to the activity in the experiment. The difference between the model and the laboratory experiment was less than 5% which showed a good accuracy. The results of this study once again showed that optimization method effectively reduced time, chemicals, and energy.
