Catholic Schools and STEM (Science, Technology, Engineering, and Mathematics): An Exploration of Stakeholders' Interest and Perceptions of STEM Programs in Elementary Schools
No full textTo remain competitive in the educational market, Catholic elementary schools are exploring alternatives, such as STEM education, to incorporate into their learning environments. In this qualitative phenomenological study, 16 interviews were conducted in Catholic elementary schools to understand their perspectives on developing and implementing a STEM program. The experiences of a pastor, three principals, two STEM coordinators, six teachers, and four community stakeholders were analyzed. Eight themes emerged: (a) shared leadership, (b) professional development, (c) curriculum and instruction, (d) STEM program evaluation, (e) STEM culture, (f) enhanced interest in innovation, (g) strategic planning, and (h) the COVID effect. Recommendations focus on developing a STEM committee/assigning a STEM coordinator, designing professional development centered on STEM, establishing program evaluation and stakeholders’ feedback, engaging in STEM strategic planning, and creating a STEM culture. The findings could help Catholic school leaders to develop and implement a STEM program.

No-go limitations on UV completions of the Neutrino Option
No full textWe discuss the possible origin of the Majorana mass scale(s) required for the “neutrino option” where the electroweak scale is generated simultaneously with light neutrino masses in a type-I seesaw model by common dimension four interactions. We establish no-go constraints on the perturbative generation of the Majorana masses required due to global symmetries of the seesaw Lagrangian.We discuss the possible origin of the Majorana mass scale(s) required for the "Neutrino Option" where the electroweak scale is generated simultaneously with light neutrino masses in a type-I seesaw model, by common dimension four interactions.

Rotational invariance of trellis codes. I: Encoders and precoders
No full textWe present a theoretical framework for rotational invariance of trellis codes. The distinction between codes and encoders plays a pivotal role. Necessary and sufficient conditions for rotational invariance are derived under general assumptions, and a construction is presented that obtains a rotationally invariant encoder for almost any rotationally invariant code, independent of the code's algebraic structure. Encoders that use a differential precoder are considered as a separate case, where a system-theoretic characterization of precoding is used to find two alternative and slightly less general encoder construction

Rotational invariance of trellis codes. II: Group codes and decoders
No full textFor pt.I see ibid., vol.42, no.3, p.751-65 (1996). In Part I, general results on rotationally invariant codes and encoders were derived assuming no algebraic structure. In Part II, trellis codes based on group systems are considered as a special case for which code and encoder constructions are particularly simple. Rotational invariance is expressed as an algebraic constraint on a group code, and algebraic constructions are found for both “absorbed precoder” encoders and for encoders with separate differential precoders. Finally, the various encoder forms used to achieve rotational invariance are compared based on their performance on an AWGN channel
