The Extraordinary In The Ordinary: Nineteenth Century Female Teachers and Their Professionalization Of An Occupation
Get PDFWomen’s occupation as teachers has remained uncritically relegated to the sphere of women’s work. In reality however, early nineteenth century female teachers made clear articulations how they understood their occupations as teachers. Through their publications, autobiographies, and biographies written by former pupils, they left behind for current educators their estimations of the integral job they performed. As educators, these women maintained the paramount role of educating the nation’s next generation of citizens. This was of particular importance in the aftermath of the American Revolution when America’s children were subjected to lacking, colonial education experiments. Before and during the ensuing common schools movement, middle-class, educated women seeking personal and economic autonomy actively participated in expanding their role to the classroom within the bounds of Victorian separate spheres ideology. Once in classrooms, female teachers professionalized the occupation through their pedagogy, expansion of their own knowledge, and connection to their community. Within the walls of the schools they started, Catharine Beecher, Julia Tevis, Martha Hazeltine Smith, Mary Anna Longstreth, and Elizabeth “Lizzie” Spear, laid the foundation for later female reformers in the Progressive era which made profound calls for themselves and America’s children from their allotted private space in public
Assessing Experiences of Women in MEP Field and Project Management Roles
Get PDFDespite increased enrollment of women in construction education programs, the industry is not seeing significant gains in the percentages of women, especially in field and project management roles. This study looks specifically at the experiences of women in the Mechanical, Electrical, and Plumbing (MEP) sector working in field and project management. Women in different career stages were interviewed to gain perspective on the state and climate of the industry from a woman’s perspective. The interviews were analyzed for recurring themes and three primary themes that emerged were: 1) women see themselves as able to bring about better team synthesis than their male counterparts, 2) there is a lack of female role models and support systems for women within the industry, and 3) women feel a need to become a construction superwoman in order to achieve success. The implications of these phenomena are that women are faced with unnecessary gender-based challenges that hinder their success, and this is not in the best interest of the industry. The results of this study confirm that previously recognized challenges for women in construction are current challenges for women in MEP field and project management roles
Augmented Reality In Construction
Get PDFThis research focuses on how augmented reality (AR) technology could assist construction projects by increasing quality control, efficiency, and collaboration. AR tools, such as Revizto, overlay 3D models into real-world construction sites, allowing the project teams to test installations and discover issues before they occur. This study aims to determine how AR affects project costs, the construction schedule, and quality. To further understand this, interviews were conducted with McCarthy Builders\u27 Virtual Design and Construction (VDC) employees. They discussed their experiences with AR on active job sites, including its benefits, limitations, and potential improvements. Studies from an internship with McCarthy Builders revealed real-world examples of AR in operation, such as ensuring metal studs and MEP systems matched the project\u27s 3D model. The results show that AR improves communication, holds trade partners accountable, and decreases mistakes during construction. However, obstacles such as expensive costs, technological concerns, and worker resistance limit this application. Overall, augmented reality (AR) is a potential technology for increasing construction efficiency and accuracy. It has the potential to save time and money, but additional effort is needed to make it more user-friendly and cost-effective
A Pedagogy of Peace & Prose: Helping Students Engage with and Articulate Perspectives on the Plight of Palestine Through a Tripartite Textual Analysis
Get PDFDevelopment of a Versatile Switching Mode Inverter Laboratory Module
No full textDC-AC converters, or inverters, are complex devices that play an essential role in photovoltaic, energy storage, and microgrid systems. Therefore, they constitute a class of power electronics that any power-focused electrical engineering student should be familiar with. This thesis presents the development and testing of a single device that power electronics students will use in a laboratory setting to experiment with each of the four different switching techniques employed in inverters: a simple square wave (SSWI), modified square wave (MSWI), bipolar PWM, and unipolar PWM. The module was built with a physically modifiable control stage and a power stage constituting an integrated-FET full-bridge driver and a removable LCL filter. These two stages combined make for a laboratory module that allows students to control the parameters in each of the switching techniques and observe the effects on the resulting AC output voltage. Furthermore, the disconnectable LCL filter allows for observing the inverter outputs both with and without filtering. The tests on the module, which are outlined in this report, verify these functionalities and demonstrate the module’s versatility as a learning tool for switching mode inverters in the laboratory environment
Design of a Novel Low-Cost Hybrid V-Shape Spoke-Type Ferrite IPM-SYNRM For EV Traction Using FEM Software
Get PDFThis paper presents a hybrid V-shape spoke type ferrite Interior Permanent Magnet Synchronous Reluctance Machine (PMA-SynRM) for electric vehicle traction application. Ferrite or ceramic IPM-SynRMs compared to Neodymium (NdFeB) based IPM-SynRMs typically have lower torque, power density, and efficiency overall. Motivated by rising costs and international policies making it increasingly more challenging to obtain rare-earth metals, alternatives should be explored. With the help of finite element method (FEM) software, Ansys Maxwell, this study probes into a novel three-phase ferrite-only hybrid Spoke-type V-shaped IPM-SynRM using Tesla Model 3\u27s neodymium powered V-shape interior permanent magnet machine as a benchmark. The proposed motor design currently exhibits 78% of maximum torque with similar torque ripple percentage and a nearly equivalent base speed of 3900 RPM versus 4100 RPM. A comprehensive cost and weight analysis reveals that the total cost of magnets can be reduced to under 5% from ~66, using Ceramic-5 instead of N42SH neodymium magnets
