Ethics Panel for Engineering Students and Practitioners

Organized by: Dr. Mümtaz Üsmen


Professionalism and ethics are important skills needed for success in an engineering career. ABET EAC and international accreditation criteria emphasize the need for the students to develop an understanding and appreciation of relevant concepts and issues. Students are introduced to related topics in their curriculum and course work to varying degrees; however, they do not frequently get the opportunity to interface with experienced academicians and engineering practitioners to obtain their perspectives and to gain exposure to their experiences and wisdom. Practicing engineers also need to learn more about ethics principles, issues and ways of resolving ethical dilemmas in their professional work.


To provide opportunities for engineering students and engineering practitioners to interact with an ethics panel of experienced academicians and engineers , so they can learn more about ethical principles and issues, obtain informed perspectives , and gain an understanding of real life situations concerning professionalism and ethics.


A panel is constituted from experienced academicians and practitioners. Prof. Dr. Mumtaz Usmen is assigned to serve as the moderator of the panel. The group of academicians supporting this event (see the e-mail list) collects questions concerning professionalism and ethics from the students in their respective universities and forwards them to the panel. These questions are reviewed  and possibly consolidated (by combining similar questions, eliminating marginal questions, and so on). The panelists are given a chance to review the questions before coming to the conference, so they can do some preparation for their answers. The moderator coordinates the preparation activities. In the beginning of the event, the moderator makes a brief presentation on ethical principles and issues, and on the panel’s objectives and procedures. This is followed by going through the pre-prepared questions by the panelists. The moderator ‘s role is to pick up each question, and go around in a round robin fashion to direct the panelists to  answer the questions (within a reasonable time limit). After each of the panelists answers a given question, the moderator opens it up for further discussions and Q and A between the audience and the panelists. This process continues until all the questions are answered and discussions completed.

This exercise can be accomplished between 60 and 90 minutes, depending on the number of panelists (no more than 4 or 5 is recommended) and the number of questions (about 6 or 7 is reasonable). It is important that good clock management is exercised by the moderator to ensure effective interactions between the students and the panelists.

Expected Outcomes

The main outcome of the ethics panel is an improved understanding and appreciation of engineering ethics by the students and engineering practitioners, and the possible realization that ethical issues are omnipresent in professional practice. Real life situations are covered by the panel to emphasize upon the audience that engineers may face ethical dilemmas and challenges, and there are ways of seeking and finding viable solutions. The panel also brings up examples of good ethical behavior and impress upon the audience that there are many positive role models in the community who have the highest degree of professionalism and integrity.

Geosynthetic Interlayer Systems in Pavements: Effectiveness and Optimization

Interlayer systems have received considerable attention in recent years as viable solutions to enhance pavement performance. Geosynthetic materials may be utilized in both bound and unbound layers of a pavement structure. The success of using geosynthetics in pavements have shown substantialpotential for increasing pavement service life and improving pavement performance if appropriately used and installed. Geosynthetics have been used in roadway systems for reinforcement, layer separation/stabilization, drainage, strain tolerant, and as moisture barriers. The challenge is usually to select the appropriate interlayer system for the proper application. In his presentation, Professor Al-Qadi will discuss the potential to enhance the performance of roadways when using geosynthetics in pavement systems as well as potential challenges. He will also present the various optimized applications to enhance the effectiveness and efficiency of the pavement system with geosynthetics.

Esnek Üstyapılarda Geosentetiklerin Kullanımı, Etkinliği ve Tasarımında Optimizasyonu

Katmanlar arası kullanılan sistemler geçtiğimiz yıllarda üst yapı performansın arttırılmasında güvenilir bir alternatif haline gelmişlerdir. Bu bağlamda geosentetiklerden gerek asfaltta gerekse üst yapının diğer katmanlarında faydalanılmaktadır. Geosentetiklerin başarılı kullanımı, doğru yerleştirildiğinde ve kullanıldığında, üst yapının servis ömründe ve performansında da önemli bir artışa neden olmaktadır. Geosentetikler yollarda güçlendirme, katmanların ayrım ve stabilizasyonu, drenaj, birim deformasyonların tölere edilmesi ve nem bariyeri oluşturmak amaçlarıyla kullanılmaktadırlar. Burada önemli ve zor olan, verim alınabilmesi için tabakalar arası en uygun sistemlerinin seçilmesidir. Profesör Al-Qadi sunumunda, üst yapı sistemlerinde geosentetik kullanımın yol performansının geliştirilmesine katkısı konusunu ele alacaktır. Kendisi ayrıca üst yapılarda geosentetik kullanımının etkisinin ve verimliliğinin geliştirilmesi amaçlı optimum uygulamalardan örnekler sunacaktır.
