    Instructional Designers as Project Managers: A Phenomenology

    The ability to effectively manage learning design projects, consult with stakeholders (such as sponsors, subject matter experts, and learners), and direct projects to completion is a vital part of an instructional designer’s role. Although the need for project management education and experience is reiterated in the literature and in cross-industry instructional designer (ID) job postings, it was unclear how these professionals acquired and used project management skills and tools in their profession because project management is not a focus in many higher education programs intended to prepare instructional designers. The goal of this phenomenological study was to understand the lived experiences of practicing instructional designers as project managers. Results describe how instructional designers practice project management and the best practices, models, methods, tools, and technologies that they use to acquire and apply project management knowledge and skills in their learning design projects. Five themes emerged from the analysis: ID/Project Management (PM) Background, PM Role Characteristics, PM Challenges, PM Insights, and PM Recommendations. During the analysis process, 14 codes (each corresponding to a theme) were exposed. The ID/PM Background theme consisted of ID/PM-related Experience, PM Preparation, and PM Competencies. PM Role Characteristics included Primary Responsibilities, Models Used, and Tools Used. PM Challenges encompassed the PM Challenges and Avoid/Overcome PM Challenges codes. PM Insights comprised PM Preparation Feelings, PM Experience Feelings, and PM Models/Tools Feelings. The theme, PM Recommendations, included codes for PM Preparation Recommendations, PM Model/Tool Recommendations, and PM Recommendations. An examination of themes that emerged from the instructional designers’ stories, along with an exploration of the research questions yielded important findings. The study offers recommendations for academia and industry for preparing instructional designers to manage their projects in professional practice

    Multirate cascaded discrete-time low-pass ΔΣ modulator for GSM/Bluetooth/UMTS

    This paper shows that multirate processing in a cascaded discrete-time ΔΣ modulator allows to reduce the power consumption by up to 35%. Multirate processing is possible in a discrete-time ΔΣ modulator by its adaptibility with the sampling frequency. The power reduction can be achieved by relaxing the sampling speed of the first stage and increasing it appropriately in the second stage. Furthermore, a cascaded ΔΣ modulator enables the power efficient implementation of multiple communication standards.@The advantages of multirate cascaded ΔΣ modulators are demonstrated by comparing the performance of single-rate and multirate implementations using behavioral-level and circuit-level simulations. This analysis has been further validated with the design of a multirate cascaded triple-mode discrete-time ΔΣ modulator. A 2-1 multirate low-pass cascade, with a sampling frequency of 80 MHz in the first stage and 320 MHz in the second stage, meets the requirements for UMTS. The first stage alone is suitable for digitizing Bluetooth and GSM with a sampling frequency of 90 and 50 MHz respectively. This multimode ΔΣ modulator is implemented in a 1.2 V 90 nm CMOS technology with a core area of 0.076 mm2. Measurement results show a dynamic range of 66/77/85 dB for UMTS/ Bluetooth/GSM with a power consumption of 6.8/3.7/3.4 mW. This results in an energy per conversion step of 1.2/0.74/2.86 pJ

    Best practices for Krakow 2016 and Dublin 2018

    AbstractLarge events present institutions a unique and powerful opportunity to communicate its message. It appears that the Church has recognized this communications tool all through its history, but in a specific way over the last 30 years in which both World Youth Days and World Meetings of Families began. Given the nature of these events as unequalled communications opportunities, it is of equal importance that organizers of large Church events prioritize the communicative dimension, understanding it as key to the success of the event itself. The scope of this paper is not only to aid organizers in understanding the importance of communications, but also to provide the communication directors of large Church events with some guiding best practices. The authors focus on ten best practices specifically, ordered from strategic to tactical, which are based on official reports and past personal experiences, making the work more practical than theoretical in nature

    First-order magnetic and structural phase transitions in Fe1+y_{1+y}Sex_xTe1−x_{1-x}

    Full text link
    We use bulk magnetic susceptibility, electronic specific heat, and neutron scattering to study structural and magnetic phase transitions in Fe1+y_{1+y}Se% x_xTe1−x_{1-x}. Fe1.068_{1.068}Te exhibits a first order phase transition near 67 K with a tetragonal to monoclinic structural transition and simultaneously develops a collinear antiferromagnetic (AF) order responsible for the entropy change across the transition. Systematic studies of FeSe%_{1-x}Tex_x system reveal that the AF structure and lattice distortion in these materials are different from those of FeAs-based pnictides. These results call into question the conclusions of present density functional calculations, where FeSe1−x_{1-x}Tex_x and FeAs-based pnictides are expected to have similar Fermi surfaces and therefore the same spin-density-wave AF order.Comment: 5 pages, 3 figure
