Bkj Diss Final.Pdf (2.562Mb) Between Discipline and Profession A History of Persistent Instability in the Field of Computer Engineering, circa 1951-2006 by Brent K. Jesiek Dissertation submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Science and Technology Studies Gary L. Downey (Chair) Janet Abbate Daniel Breslau Timothy W. Luke Michael S. Mahoney (Princeton University) December 13, 2006 Blacksburg, VA Keywords: history, computer, computing, design, technology, engineers, engineering, engineering studies, discipline, profession, instability Copyright 2006, Brent K. Jesiek Between Discipline and Profession A History of Persistent Instability in the Field of Computer Engineering, circa 1951-2006 by Brent K. Jesiek Abstract This dissertation uses a historical approach to study the origins and trajectory of computer engineering as a domain of disciplinary and professional activity in the United States context. Expanding on the general question of “what is computer engineering?,” this project investigates what counts as computer engineering knowledge and practice, what it means to be a computer engineer, and how these things have varied by time, location, actor, and group. This account also pays close attention to the creation and maintenance of the “sociotechnical” boundaries that have historically separated computer engineering from adjacent fields such as electrical engineering and computer science. In addition to the academic sphere, I look at industry and professional societies as key sites where this field originated and developed. The evidence for my analysis is largely drawn from journal articles, conference proceedings, trade magazines, and curriculum reports, supplemented by other primary and secondary sources. The body of my account has two major parts. Chapters 2 through 4 examine the pre- history and early history of computer engineering, especially from the 1940s to early 1960s. These chapters document how the field gained a partially distinct professional identity, largely in the context of industry and through professional society activities. Chapters 5 through 7 turn to a historical period running from roughly the mid 1960s to early 1990s. Here I document the establishment and negotiation of a distinct disciplinary identity and partially unique “sociotechnical settlement” for computer engineering. Professional societies and the academic context figure prominently in these chapters. This part of the dissertation also brings into relief a key argument, namely that computer engineering has historically occupied a position of “persistent instability” between the engineering profession, on the one hand, and independent disciplines such as computer science, on the other. In an Epilogue I review some more recent developments in the educational arena to highlight continued instabilities in the disciplinary landscape of computing, as well as renewed calls for the establishment of a distinct disciplinary and professional identity for the field of computer engineering. I also highlight important countervailing trends by briefly reviewing the history of the software/hardware codesign movement. Acknowledgments First and foremost, I thank my family for their encouragement and understanding as I worked on this project, as well as my graduate degrees more generally. In fact, this dissertation may have never been completed without the extensive support – and gentle prodding – provided by my wife Julie and son Preston. Thanks also to my parents for their continued encouragement in all of my endeavors, no matter how seemingly far-flung. I owe another debt of gratitude to my many friends and colleagues at Virginia Tech – for the most part, you know who you are. But I especially want to thank Jody Roberts for many conversations that helped enrich this document. I also acknowledge Shelli Fowler, who not only greatly encouraged and supported me as a graduate student, but who is also an all-around exemplary colleague and mentor. Following her model, I fully intend to pay the favor forward. Members of Virginia Tech’s Research in Engineering Studies (RES) group, on the other hand, deserve mention for being willing and thoughtful commentators on an early draft of Chapter 2. I am of course much indebted to each and every one of my committee members, who from the start saw the value and potential of this project, and helped nurture it along the way. Their willingness to thoughtfully engage with a large body of draft material and provide countless valuable suggestions made this a much better document. I very much look forward to continuing our conversation about this material in coming months and years. Gary Downey, in particular, has been an outstanding committee member and chair throughout this process, and I thank him for both keeping me on schedule and pushing me to figure out where my analysis was headed. At countless points along the way, Gary helped me see the proverbial forest for the trees when I found myself neck-deep in historical details. There are still others worthy of mention, including the many library staffers who retrieved or tracked down sources for me. Staff at the Charles Babbage Institute, National Academies, and IEEE History Center also deserve mention for responding to many queries and for finding and sending me relevant materials. Again, I thank you all. iv Table of Contents ABSTRACT..................................................................................................................................

  • Engineering Futures 2035 Engineering Education Programs, Priorities & Pedagogies
    Engineering Futures 2035 Engineering Education Programs, Priorities & Pedagogies __________________________________________________________________________________________ Caroline Crosthwaite February 2021 Executive Summary The 2019 scoping study ‘Engineering Futures 2035’ commissioned by the Australian Council of Engineering Deans (ACED) investigated drivers of change, the anticipated nature of future professional engineering work, and engineering education programs that will be needed to produce fit-for-purpose graduates. Engineers of the future will require greater abilities to find and define problems before finding solutions. Both problem definition and solution will require a deeper ability to communicate and empathise with a broader range of stakeholders than has been required in the past. A greater focus on the human dimensions of engineering work and increasing complexity is also anticipated. Further details of the anticipated changes in the nature of professional engineering work and the capabilities that will be expected of future engineering graduates are provided in Section 1. The purpose of this report is to follow up on the ACED scoping study recommendation number 2 by presenting a critique of applicable developments in engineering education, referencing national and international best practice, and emerging educational models within the higher education sector. This includes identifying exemplary engineering education programs, program models, curriculum contexts and pedagogies that have the potential to support the delivery of the T-shaped engineering graduate and the greater breadth of graduate outcomes that will be required in future. Given the large engineering student numbers at many Australian universities, scalability, and possible barriers to widespread implementation of desirable changes are of particular interest. Consultation with national and international engineering educators and scholars collected views on program architectures, curriculum and pedagogies that will be instrumental in delivering on future graduate expectations.

  • The Contribution of Qualitative Research Towards the Issues Affecting Female Undergraduate Engineering Students
    The Contribution of Qualitative Research towards the issues affecting Female Undergraduate Engineering Students Louise Duggan 29/5/2015 Department of Engineering, Letterkenny Institute of Technology, Port Rd., Letterkenny, Co. Donegal, Ireland [email protected] Abstract This article explores the use of qualitative research methods towards our understanding of the issues affecting female undergraduate engineers. As outlined in this article female engineering students face many challenges during their undergraduate studies. Qualitative research methods provide an opportunity to gain a deeper understanding of the issues affecting female undergraduate engineering students. Qualitative research provides an opportunity to gain rich data that simply would not be possible using quantitative methods. This article critically appraises three qualitative articles discussing the issues affecting the female undergraduate engineer and highlights the contribution that each article makes towards our overall understanding of the undergraduate female engineering experience. This article concludes that qualitative research methods provide invaluable data and has the potential to uncover new phenomenon. Keywords qualitative research, female, undergraduate, engineering Introduction Qualitative research is primarily concerned with understanding phenomena in depth and in its natural environment. Denzin and Lincoln (2005) define qualitative research as ‘a situated activity that locates the observer in the world. It consists of a set of interpretive, material practices that make the world visible’ (p 3). The very nature of this definition emphasizes the importance of the setting or the context of the phenomenon under investigation. Similarly, Hatch (2002) describes some of the recurring characteristics of qualitative research, particularly the natural environment, prolonged contact, emphasis on meaning, inductive data analysis and emergent design.

  • Istorija-Racunara
    Istorija računara Pripremila Irena Gonda Uvod Uticaj revolucije informacija na naše društvo i industriju je ogroman. U sve većoj želji da kontrolišemo sopstvenu sudbinu mi ne želimo samo da shvatimo trenutnu tehnologiju nego i da provirimo u prošlost kako bismo prepoznali trendove koji nam mogu omogućiti da predvidimo neke elemente budućnosti. Gledanje u nazad da bi se otkrile paralele i analogije sa modernom tehnologijom može obezbediti osnove za razvoj standarda po kojima možemo proceniti izvodljivost i potencijal tekuće ili predložene aktivnosti. Ali mi takođe imamo osećaj odgovornosti za očuvanje dostignuća naših prethodnika kroz uspostavljanje arhiva i muzeja uz očekivanje da će zadovoljstvo otkrivanja prevazići profitabilnost puke istorijske apstrakcije. Rane godine U ranim danima kalkulacija je bila potrebna onda kada je trebalo izvestiti o individualnim ili grupnim postupcima, pogotovo u vezi sa održanjem inventara (grupe ovaca) ili usklađivanjem finansija. Ranije su ljudi računali poređenjem jednog skupa objekata sa drugim (kamenje i ovce). Operacije dodavanja i oduzimanja bile su jednostavno operacije dodavanja ili oduzimanja grupa objekata na gomilu kamenja ili šljunka koja je služila za računanje. Prve table za računanje zvale su se abaci i nisu samo stvorile ovaj metod računanja nego su i uvele koncept pozicionog označavanja, koji i danas koristimo. Sledeći logični korak bilo je pravljenje prvog "personalnog kalkulatora" - abakus (engl. abacus) -- koji koristi isti koncept, da jedan skup objekta zamenjuje drugi skup, ali i koncept da jedan objekat zamenjuje kolekciju objekata -- poziciono označavanje. Ovaj odnos jedan prema jedan nastavio se kroz mnoga stoleća, čak i kada su prvi kalkulatori koristili poziciju rupe na krugu da bi označili broj -- kao kod telefona koji ima kružni brojčanik.

No. 2, July 2009, pp. 101-127 Abstract Cycles of reform have been a constant feature of engineering education. This paper suggests that these cycles are endemic because engineering begins with a particularly instrumental conception of responsible preparation. The instrumental logic of engineering repeatedly undermines educational reforms seeking to cultivate the capacities for discretionary interpretation and judgment at the root of professional practice.

  • Making Programming Masculine 6
    Making Programming Masculine 6 NATHAN ENSMENGER I n the April 1967 issue of Cosmopolitan magazine, sandwiched between “ The Bachelor Girls of Japan ” and “ A Dog Speaks: Why a Girl Should Own a Pooch, ” there appeared a curious little essay entitled simply “ The Computer Girls.” As the article explained, these were the female “ computer programmers ” who taught the dazzling new “ miracle machines” called computers “ what to do and how to do it. ” There were already more than 20,000 women working as com- puter programmers in the United States, argued the article ’ s author, Lois Mandel, and there was an immediate demand for 20,000 more. Not only could a talented “ computer girl” command as much $20,000 a year, but the opportunities for women in computing were effectively “ unlimited. ” The rapid expansion of the computer industry meant that “ sex discrimination in hiring ” was unheard of, Mandel confi dently declared, and anyone with aptitude — male or female, college educated or not — could succeed in the fi eld. And not only were women in computing treated as equals, but they actually had many advantages over their male colleagues. Programming was “ just like planning a dinner, ” Mandel quoted the noted computer scientist Dr. Grace Hopper as saying, “ You have to plan ahead and schedule everything so it ’ s ready when you need it. Programming requires patience and the ability to handle detail. Women are ‘ naturals ’ at computer programming ” [1] . It would be easy to dismiss “ The Computer Girls ” as a fl uff piece, a half - hearted attempt by Cosmopolitan to capitalize on contemporary interest in the computer revolution.
