Abstract:
In this study, there is an attempt to teach simple mathematical concepts of fractional numbers to Secondary School students in Technical School who, despite their age, had not previously managed to understand these concepts. At the same time, to further the success of this undertaking, we also examined the emotions generated in the students. The whole undertaking is shown to be successful, since the students understood the particular concepts taught, and the significant role played by a teacher's ability in the feelings of the students regarding the above approach is realized, since teachers with different abilities created different feelings in their students.

Abstract:
Although higher rates of substance use among young adults aged 16 to 24 are well-established (OAS, 2010), existing workplace substance use prevention and early intervention programs primarily target older workers. These data suggest that workplaces need substance abuse prevention and early intervention programs that are proven to be efficacious with young working adults. To address this critical need in American workplaces, in 2004 the Substance Abuse and Mental Health Services Administration (SAMHSA) announced its Young Adults in the Workplace initiative (originally entitled Youth in the Workplace [YIW]) (SAMHSA, 2004). The YIW initiative was designed as a two-phase collaborative effort among SAMHSA investigators, multiple grantees, and a coordinating center. It was conceived as a mechanism to test the efficacy of workplace substance use prevention or early intervention programs for young working adults aged 16 to 24. In Phase I, SAMHSA required grantees to develop workplace programs by starting with interventions shown to be efficacious either for adults in workplace settings or for young adults in non-workplace settings and to modify these programs specifically for use with young adult workers. In Phase II, SAMHSA funded a subset of the Phase I grantees to implement the workplace programs and to participate in a cross-site evaluation of the YIW initiative conducted by the Coordinating Center. Based on a peer-review process, SAMHSA funded 13 Phase I grantees and 6 Phase II grantee teams (including workplace partners). This publication briefly describes the background and rationale for the YIW initiative, presents the interventions implemented by the six YIW grantees, and provides an overview of the methods and design of the cross-site evaluation. Chapters in this book include: (1) The Young Adults in the Workplace Initiative: An Introduction (Deborah M. Galvin, William Schlenger, and Johannes Norling); (2) Healthy WorkLife for Young Adults: Implementing Health Promotion and Substance Abuse Prevention in a Health Care Setting (Rebekah K. Hersch, Royer F. Cook, Daniel Hughes, Samantha L. Leaf, and Douglas W. Billings); (3) Substance Abuse Prevention for the Young Workforce in the Railroad Industry: An Adaptation of the PREVENT Program (Rebecca Spicer, Ted Miller, and Eduard Zaloshnja); (4) Team Resilience: Health Promotion for Young Restaurant Workers (Joel B.

Abstract:
Two possible topical approaches that have been applied to teaching an upper-division undergraduate electrical engineering applied electromagnetics course are presented. Each approach was applied to one of two offerings of the course, taught in different semesters. In either case, the course includes the study of electromagnetic theory and practical applications through laboratory experiments, design and projects. Using basic theory in time-harmonic electromagnetic fields developed early in the course, two different applications of the theory are emphasized in two alternate semesters of the course offering. The two applications that incorporated the common theoretical background of the course are: (1) applications in radio frequency engineering; and (2) radar and antenna design. An extension of the course to a topic beyond the confines of the course textbooks is included. The success of the course is further realized in two industry-sponsored capstone senior design projects.

Abstract:
Ac-powered contactors are extensively used in industry in applications such as automatic electrical devices, motor starters, and heaters. In this work, a practical session that allows students to model and simulate the dynamic behavior of ac-powered electromechanical contactors is presented. Simulation is carried out using a rigorous parametric model of the ac contactor that avoids simplification assumptions and is thoroughly explained. The goal of this practical is to introduce students to the topic of dynamic simulation of real devices. It covers both the transient and the steady-state response of the electromechanical system under study. The proposed methodology is flexible and not particularly time-consuming, and it allows the students easily to change the electromechanical constants of the contactor they are studying. The results of the simulations were compared with experimental data acquired by the students; a close similarity between real and simulated data was observed. The Technical University of Catalonia (UPC), Spain, has incorporated the simulation methodology proposed in this paper in a practical session of an electrical engineering course.

Abstract:
Electricity and magnetism are intimately linked, this relationship forming the basis of the modern electric utility system and the generation of bulk electrical energy. There is rich literature from which to teach students the basics, but nothing drives the point home like having them learn from firsthand experience--and that is what this challenge is all about. This article presents magnetism and electricity activity that attracts student interest. Using a simple compass, students detect magnetic fields all around them, then draw conclusions based on their findings.

Abstract:
This study explores the impact of the electrical and technology curriculum of an urban charter high school in Philadelphia for the alumnae of the school. The study found a positive impact that empowered the alumnae to face gender and racial discrimination in their apprenticeship program. It also found a positive impact for alumnae that are not pursuing a path in the trades but instead are either in college or the working world. The alumnae shared their pride in having this knowledge that is from a traditionally male field. A critical postmodern feminist approach was taken in constructing this qualitative study. The entire alumnae of the school were contacted and three individuals discussed their experiences with the curriculum and how they have used it in their every day lives. The study presents the alumnae's voices and stories to demonstrate the positive impact of the curriculum for their lives.

Abstract:
As Australia's economy recovers from the economic downturn, attention is turning once again to skills shortages. To gain insights into the labour market for tradespeople, this report investigates changes in supply, demand and how adjustment occurred through the varied economic conditions of the past 20 years. It concludes that there was no overall severe shortage of tradespeople during the recent boom time but that some local labour markets experienced excess supply or demand. Migration (both from overseas and internally) and wage adjustments appear to have been important functions in responding to these conditions. (Contains 14 tables and 16 figures.)

Abstract:
This paper presents experiences and results from a project task in power electronics for students at Chalmers University of Technology, Goteborg, Sweden, based on a flyback test board. The board is used in the course Power Electronic Devices and Applications. In the project task, the students design snubber circuits, improve the control of the output voltage, improve the gate drive of the main MOSFET transistor and study the influence of stray inductance. The project goals (the circuit improvements) are given, but the procedure for solving the problems and obtaining the results is not specified. Instead the students have to make their own specification in order to reach the goals. "Tools" that are given to the students are the hardware, measurement equipment, an example of the circuit in the circuit simulation software PSpice, and lastly lectures covering the material needed in order to attain the project goals. The project design builds on the ideas from the CDIO (Conceive, Design, Implement, Operate) initiative, where students are encouraged to consider the complete process structure. The result found was a substantial engagement by the students, who had both positive and negative reactions. The negative reactions were mainly that the project specification was too vague, in other words in the (C=Conceive)-phase of the CDIO structure. Further, the teachers observed increased learning, which also was noticeable for the students performing their M.Sc. thesis within the power electronics design area. Finally, it was found that a final written exam is definitely still needed to assess students adequately in the course. (Contains 11 figures and 1 table.)

Abstract:
This article talks about solar photovoltaic (PV) installer and features Rebekah Hren, a solar PV installer who puts solar panels on roofs and in other sunny places to turn the sun's power into electricity. Hren enjoys promoting renewable energy, in part because it's an emerging field. In solar PV systems, solar cells--devices that convert sunlight into electricity--are joined to create different types of solar modules, which are usually further connected. Solar electric systems can be installed on the ground, on poles, or on the roofs or sides of buildings. The U.S. Bureau of Labor Statistics does not publish employment data on solar photovoltaic installers. But industry sources suggest that there are about 7,000 solar photovoltaic installers--who may also be known as solar photovoltaic technicians or solar installer-roofers--in the United States. As the use of solar power expands, the job tasks of solar PV installers are evolving. Some workers concentrate primarily on installing the panels. Others, especially those at small companies, do everything from sales to planning to wiring. Experienced installers in any size company may advance to lead installer, system designer, sales representative, or other positions.

Abstract:
Purpose: The purpose of this paper is to outline the approach taken within Kentz Engineers and Constructors to develop electrical technicians and other apprentices on an international basis. Design/methodology/approach: The approach adopted is that of a case study which describes activities and processes within the college and the rationale behind them supported by appropriate material. Findings: An integrated approach is needed to developing qualified tradespeople as junior supervisors involving work rotation, mentoring, learning and development workshops and peer support. Corporate will, together with systems and infrastructure, is needed to be successful organization-wide. Research limitations/implications: The paper is a case study that focuses on reflections from practice. Lessons learned and proposed will need to be tested in other organizations. Originality/value: The paper provides original, tested solutions to problems that face the majority of organizations in the global construction industry and which will be familiar to all who manage the transition of apprentices into supervisory positions.
