    There is ever growing interest in sensitive detection of short wavelength (SWL) radiation, ultraviolet (UV) and X-rays. We report on our efforts to develop sensitive SWL detectors based on the nanoparticles (NPs) of lanthanide (Ln) doped Cs-Pb-bromide perovskite and oxysulfides that down-convert the spectrum of SWL radiation into visible and near-infrared (NIR) light. The spectrum of this light matches the spectral response of inexpensive and rugged silicon avalanche photo diodes (APDs) and image sensors with an electron gain of >106. Synthesized Eu-doped perovskite NPs demonstrated a down-shifted visible-NIR photoluminescence (PL) response to UV radiation with the spectral peaks attributed to both perovskite matrix and Eu dopant. A scintillating screen made of red nanophosphor Gd2O2S: Eu was used for X-ray see-through imaging of a metal object hidden in an opaque medium. Integration of the nanophosphor with a silicon APD made it possible to detect pulsating X-rays at frequencies of 20 and 40Hz with a signal-to-noise ration of ~5. The results obtained might be used in the field of sensitive detection of SWL radiation.

  4. Teamwork has been identified as one of the essential professional skills for the 21st century. Business, industries, and corporates require their employees to work in teams on various projects. Therefore, it is crucial to introduce and train undergraduate students on teamwork skills. Working in teams is not easy as one needs to collaborate with people from diverse backgrounds, skillsets, and opinions. The disagreement among the team members may lead to conflict and chaos that jeopardizes the team's harmony. Therefore, just creating teams and assigning a group project is insufficient to help undergraduate students develop teamwork skills. Instructors need to help students become cognizant of their teamwork skills, such as conflict resolution, scrum values, and cultural self-awareness. In this research paper, we intend to understand the perception of students enrolled in a sophomore-level system's course regarding conflict resolution skills, scrum values, and cultural self-awareness. We also want to understand how the perception of these values is related to one another. In the light of this study, we want to answer the following research questions (1) How do students' reported conflict management skills relate to their reported scrum values? (2) How do students' cultural self-awareness relate to their conflict management skills? (3) How do students' cultural self-awareness relate to their reported scrum values? A course on system analysis and design followed a project-based cooperative learning approach. The students were required to work in teams and complete the course deliverables, including the final course project. The team projects followed a scrum approach that helped students identify the project requirements, perform modeling and develop a prototype. Since students worked on scrum- driven projects in a cooperative learning environment, the students were required to participate in a survey study that allowed the instructional team to develop an understanding of the students' perception of conflict management, scrum values, and cultural self-awareness. The responses of the students were analyzed using descriptive and inferential statistics. The results suggest that students found themselves competent in managing conflict, adhering to scrum values, and demonstrating a high-level cultural self-awareness.

  6. Working in teams has been recognized as an essential 21st-century skill. Introducing teamwork in the undergraduate classroom is crucial as it allows the students to work with individuals with diverse skillsets and learn from one another. It is important to note that just creating a team and allowing the students to work does not foster teamwork skills. Inculcating teamwork skills requires a consciousness on the part of the instructor and the teaching assistants. Pedagogies such as cooperative learning have been recognized as effective in helping students develop teamwork skills. We introduced a joint reflection on action approach to developing teamwork skills among novice students as part of a sophomore-level systems analysis and design course. In this evidence-based practice paper, we report on students’ reflections regarding their perceptions of teamwork. This study approaches the following research questions: What are students' reflections about the role of communication while working in teams in a cooperative project-based learning environment? The guiding pedagogical framework for this course is cooperative learning. The course requires the students to work in teams in a semester-long software development project. To elicit reflection on action about their teamwork experience. Specifically, we exposed students to concrete experiences as part of their teamwork interactions, which became the basis for observations and reflections. For this, the semester-long project was complemented with one reflection-on-action activity. In the activity, students were asked to watch a video of secrets of successful teamwork and were asked to reflect on their perceptions about the role of communication within teams. The students’ reflections on the activity were analyzed using qualitative inductive thematic analysis to understand the students’ perceptions regarding teamwork and communication within teams.
