Indian Perspective on Women in Computing Roli Varma School of Public Administration University of New Mexico, Albuquerque AbstractIn the United States, women pursuing higher education in computing fields has been low.Scholars have focused on the reasons behind under-representation of women in computing. Thedominant trend in the scholarly literature is that the computing fields themselves are gendered. Incontrast, there has been a significant increase in the number of women enrolling in computingfields in colleges/universities in India. The image of computing in India

This paper discusseshypothetical cases in engineering ethics in the context of instructional exercises or studentcompetitions. Recommendations are given for the development of versatile cases and forapproaching a case study or analysis. Three custom cases that were used in the IEEE StudentEthics Competition are presented as examples.KeywordsEthics, Profession, Case Study.IntroductionCase studies are valuable tools for developing knowledge and judgment concerning engineeringethics.

Students are assigned to a design team to determine the cause of the demandfluctuations, to mitigate them, to check the public utility’s measurements, and to create animportant building block for an eventual campus microgrid. Students build a metering and dataacquisition system to collect data on demand, making and recording several key measurements.They determine the cause of the demand fluctuations as being correlated to nearby constructionand maintenance interruptions in one of two electrical gateways. The public utility’s dataappears to be accurate within one percent of what
