In accordance with the recommendation from the Accreditation Commission and proposals from the Ministry of Education and Science, as well as in line with the Decision of the Riga Technical University Senate (30.10.2000.) „On the RTU Statutes” amendments have been made to the aforementioned study programmes and currently studies take place in the following study programmes:

BDB1 “Building Construction and Reconstruction”(approved in the RTU Senate on 26.03.2001, Protocol No. 457);

BDB8 “Automated Design of Building Constructions”(approved in the RTU Senate on 26.03.2001, Protocol No. 457);

BDB4 „Transportation Engineering” (approved in the RTU Senate on 28.04.2003, Protocol No. 477)

In the programmes under codes BDB1, BDB4 and BDB8 the total number of credit points has been increased from 120 credit points to 144 credit points.

According to the Decision (02.06.03.) of the RTU Senate, Protocol No.478, the aforementioned study programmes have been combined into a single program BDBO, where the directions of Automated Design of Building Constructions, Building Construction and Reconstruction, and Transportation Engineering have been maintained.

Correspondence of Study Programme to Academic Education Standard

The requirements for doctoral study programmes as prescribed in the Cabinet of Ministers Regulations No.2 „On the Standard of Academic Education” (length of studies – 3 years and scope of studies – 144 credit points) have been fulfilled..

Practical Implementation of Study Programme Methods of Instruction

Doctoral studies can be characterized by a small number of students in each study programme, consequently the studies of advanced subjects often materialize as consultations and discussions with docents of relevant subjects. This aspect of doctoral studies allows for much deeper appreciation and understanding of study material then in bachelors’ or masters’ level. The proportion of independent studies at the doctoral level thus is very significant. Often doctoral students, in order to improve their financial situation, are gainfully employed outside the university; therefore, occasionally students fall behind in the fulfilment of study plans, which finds reflection in the overall university statistics. More often than before, doctoral students obtain fellowships in universities abroad. So far, the doctoral-level students of our faculty have obtained fellowships in University of Wales (L.Pakrastiņš), Lulea Technological University (L.Pakrastiņš), Padova University (A.Zariņš). This type of study organization allows the doctoral students to improve their foreign language

proficiency and establish connections with foreign colleagues for their future careers, and undertake significant amount of scientific research. During the reference period between February 27, 2002 and June 27, 2002 O.Ozoliņš, a doctoral student in the BDB8 programme, was a fellow at Royal Institute of Technology in Sweden. During his fellowship, Ozoliņš defended his license project. A license project in Sweden is considered a higher level degree than a Masters’, but a lower level than a Doctorate. In any event, it is one of the requirements that students must pass on their way towards a doctoral degree. During the Fall Semester of 2002/2003 study year A.Ivaškovs, a doctoral student of the BDB8 programme, was a fellow at Hull University.

Professor R. Rikards is chairing grant 01.0439 “Elaboration of Methods for Optimization of Composite Materials and Constructions”

Professor K.Rocēns is participating in LSC cooperation project 02.0003 ”Materials for Latvian Economy: Elaboration of Technologies, Research of Properties, Elaboration of Rational Use Principles”

Doctoral student Boriss Jeļisejevs for two years in a row has won Latvian Civil Engineering Union scholarship competition for doctoral students of Riga Technical University and Latvia Agricultural University

In cooperation with the Latvia Education Fund and Latvia Highway Directorate, the students in the specialization of Transportation Structures have the possibility to participate in research project and scholarship competition. Every year 6 best authors of research projects and their advisors receive awards.

The number of recipients of doctoral degrees is miniscule in comparison with the number of students in bachelors’ and masters’ programs. The experience of past years indicates that after the graduation from the doctoral programme most graduates become academic staff of the Faculty of Civil Engineering of Riga Technical University. As a result, Faculty of Civil Engineering of Riga Technical University can (so far) be considered the main employer of students from this doctoral programme.

System of Assessment The mastery of study material is assessed in a 10-grade system in accordance with the Decision of the RTU Senate of January 29, 2001 “On the transition to uniform assessment of study results” and the Decision of the RTU Senate on May 25, 2001 “On criteria of assessment of study results”. Forms of examination include quizzes, study projects and exams in accordance with study plans for each academic year.

The questions in exams and quizzes are prepared by a responsible docent on the basis of the approved course syllabus and class schedule. The questions are phrased in a way that students which can respond to them in full have gained mastery of the course and has attained the stipulated course goals.

Exams are taken in accordance with the statutes approved on January 26, 1998 and March 30, 1998 “On Order of Examinations”. The assessment of knowledge is undertaken twice a year during exam sessions. The highest evaluation – grade 10 – is given to those students which, in addition to the scope of knowledge required in the study programme, have reported on the results of their research in scientific conferences, acquainted themselves with the relevant experience of other countries etc.

Students

In the Faculty of Civil Engineering the state finances 18 doctoral students. In 2002, 16 of these 18 spaces were filled. The number of admitted students in the Faculty of Civil Engineering during the

12


past years has drastically increased (Table 1). The number of doctoral students in the program of civil engineering has also grown.

During the reference period, the doctoral dissertation in construction science has been successfully defended by M.sc.ing. Dimitrijs Serdjuks and M.sc.ing. Viktors Filipenkovs. In the reference period, doctoral students Atis Zariņš, Leonīds Pakrastiņš and Genādijs Šahmenko have completed the theoretical course in full and completed the promotional project by 75%.

For some time, it has been difficult to reflect the fulfilment of the requirement to publish research material in academic journals, which are recognized as quotable in Latvia, within the last 5 years. However, after the commencement of the publication of Scientific Proceedings of Riga Technical University this problem has been resolved.

Currently, the following students are enrolled in the Civil Engineering doctoral program:

Academic Staff

Heads of scientific research work in the doctoral study programme ”Civil Engineering”: Dr.habil.sc.ing., Professor R.Rikards Dr.habil.sc.ing., Professor K.Rocēns Dr.habil.sc.ing., Professor F.Bulavs Dr.sc.ing., Professor J.Naudžuns Dr. sc.ing., Professor A.Čate Dr.sc.ing., Associate Professor A.Paeglītis Dr.sc.ing., Docent J.Biršs

Academic staff involved in the implementation of the programme: Dr.sc.ing., Associate Professor R.Ozoliņš Dr.sc.ing., Associate Professor A.Skudra Dr.sc.ing., Associate Professor J.Smirnovs Dr.sc.ing., Lecturer D.Serdjuks Dr.sc.ing. J.Barkanovs Ms.paed. Course Docent I.Siliņa (German) Ms.phil. Lecturer G.Čākure (English).

When analysing the qualitative composition of the academic personnel, it must be noted that 5 Professors, 5 Associate Professors, one Docent, one Lecturer, and one Researcher with the Dr.sc.ing. degree are involved in implementing the doctoral study programme. The share of docents with a doctoral degree (dr.sc.ing. un. Dr.sc.habil.ing) is 85% from the overall number of docents involved in the study programme. The share of docents with doctoral degrees in advanced subjects is 100%. It must be noted that in the Faculty of Civil Engineering as a whole, in comparison with year 2000, both the number of Professors and Associate Professors has increased (see Table 2):

Lecturers 56,7 44,37 - 12,33Assistants 31,7 30,50 - 1,2

The statistical average age of academic staff is 54.5 years.

Analysing the numerical composition of professorial groups and quantitative content of departments, the age distribution among them is not equal – some groups have no assistants, lecturers and support staff. It must be noted that the average age of academic staff is still very substantial, and one of the main tasks of every head of unit and the Faculty as a whole is a rejuvenation of the academic personnel. The composition of the professorial groups and departments is selected by its head, on the basis of the salary resources and tasks. Taking into account the consideration that the Faculty is preparing civil engineering specialists both with academic and professional training, the qualitative composition of the academic staff can be seen as adequate. However, from the viewpoint of future perspective, the substantial average age of academic staff raises concerns despite the fact that since 2000 the average age has somewhat decreased, since young Doctors of Engineering Science - Viktors Fiļipenko, Diāna Bajāre un Dimitrijs Serdjuks have joined the Faculty.

The SWOT analysis of Civil Engineering and Engineering Science programs (Diagram 2) allows judging that during the reference period they have been further developed and those deficiencies, which have been pointed out by the accreditation commission, for instance, the aging of academic staff, are being gradually averted.

Comparison with Study Programmes in Other Countries The following doctoral programmes in Civil Engineering were selected for international comparison: Vienna Technical University (Austria), University of Alabama (USA), Technical University in Prague (Czech Republic), and Ottawa – Carleton University (Canada).

To commence studies at the University of Alabama, Ottawa – Carleton University and Riga Technical University the applicants must have received a Masters’ degree in Civil Engineering. Applicants to Vienna Technical University and Technical University of the Czech Republic must have received the qualification of an Engineer in Civil Engineering.

The length of studies in each one of the aforementioned universities is different. It varies between the minimum time of 1 year in Alabama University and 3 years in RTU and Technical University in Prague. The Technical University of Prague also has stated the maximum time of studies – 8 years. RTU also establishes a limited time period for the completion of studies – 5 years for day studies and 7 years for distance studies.

The representatives of RTU Faculty of Civil Engineering participate in the implementation of an international project, European Civil Engineering Education and Training (EUCEET). Within the scope of this project, different levels of study programs in civil engineering are being harmonized. The participants of this project from more than 20 European countries have agreed that doctoral-level studies often are very specific and they are not subject to this harmonization process. This indicates that often each doctoral student has different academic subjects in his/her study programme. An indirect testimony to this is the fact that only two of the doctoral programs selected for comparison have defined the scope of core subjects: RTU – in the amount of 15 credit points, and University of Alabama – in the amount of 24 credit hours.

Doctoral programs, as a rule, do not enrol a large number of students; therefore, in many universities the core subjects have not been defined, and only the scope of advanced specialized subjects is specified. These subjects are selected by the doctoral student himself/herself with assistance of the research adviser in accordance with the topic of the research project. The scope of specialized subjects which has been included in the analysis is comparable and varies between 12 semester week hours (which could be compared to RTU credit points) in Vienna Technical University and 24 credit hours in the University of Alabama.

All of the programmes included in the comparison require the completion of a dissertation. The research results of a dissertation must either be published or publicly defended in front of a commission. It must be noted that both at the RTU and in Technical University of Prague, the third study year is entirely devoted to the research on a dissertation and doctoral students are not obliged to attend lectures, which frees up time for a deeper examination of a concrete problem.

Upon completion of the doctoral studies at the RTU, students receive the Doctoral degree in Engineering Science (Latin abbreviation - Dr.sc.ing.), at the Technical University of the Czech Republic, University of Alabama, and Ottawa Carleton University – Ph.D degree, but upon

17


successful completion of studies at Vienna Technical University – Doctor of Technical Sciences (in German: Doktor der technischen Wissenschaften; Latin abbreviation – Dr. techn.).

The analysis of structure and content of the programmes included in the comparative analysis (see Table 4) allows concluding that the doctoral study programme implemented in the RTU is similar to the programs offered by universities in Europe and North America. In particular, the RTU programme is similar to the one implemented in the Technical University of the Czech Republic.

Survey Results

In order to find out the opinion of doctoral students, academic staff and employers about the study programme, a survey was administered. During the survey, the respondents were asked to reply to the following questions compiled in a questionnaire:

Task Considerably Partially None

Acquire the ability to organize and undertake experiments, analyze and interpret data obtained

Acquire the ability to create a system, component or process, which allows to achieve the desired result

Acquire the ability to function in multi-discipline teams

Acquire the ability to communicate effectively and perform in front of an audience

Acquire a broad education necessary for understanding the impact of scientific discoveries upon the discipline of civil engineering

Learn the latest developments of construction science

Acquire the ability to organize teamwork in the research of scientific problems

Establish contacts with researchers from other countries, participate in conferences

Altogether 20 questionnaires were circulate, from which only 15 were received in a filled-out fashion, including 3 from employers, 6 from docents, and 6 from doctoral students. The data obtained were structured as follows:

For an answer „Considerably” +2 points were calculated For an answer „Partially” + 1 point was calculated For an answer „None” - 2 points were calculated

The number of points obtained is then compared against the possible maximum of points and expressed in percentage. In this manner, we obtain an overview of the strengths of the programme as well as the areas where further improvements are necessary. The Results have been compiled in Diagram 3.

As evident, the most critical responses have come from the employers, which have indicated that the young Doctors of Engineering Science have not acquired the ability to function in multi-discipline teams (0%) and have a weak ability to organize teamwork in the research in scientific problems (17%). This can be explained since the doctoral studies mainly focus in individual work.At the same time, employers are very satisfied (100%) by the level of knowledge in the latest developments of construction science.

22

Doctoral study program “Civil Engineering”

The doctoral students themselves give the lowest evaluation for the inadequate ability to function in multi-discipline teams (25%), but their highest evaluation relates to the ability to create a system, component or process, which allows achieving the desired result (92%).

The responses of academic staff evince that the inadequate mastery of ability to organize teamwork in the research of scientific problems causes most concern (17%). Likewise, less than half of the respondents viewed the ability of young Doctors to function in multi-discipline teams as sufficient. However, the academic personnel hold the highest opinion about the students’ ability to communicate effectively and perform in front of an audience (92%). This evinces that the young Doctors of Engineering Science to a considerable measure are ready to commence the pedagogical work in Riga Technical University, which is one of the main goals of the doctoral study programme.

The results of the survey lend credence to the assertion that as a whole the doctoral programme provides a decent theoretical preparation; yet, the development of the ability of young specialists to work in a team and organize its work needs further attention.

Recommendations for Improvement of Program Quality

During the reference period the average age of the academic staff has somewhat decreased, since a number of young colleagues have joined the teaching staff, including three new Doctors of Engineering Science. However, the issue of generational change in a few professorial groups is still very much on the agenda. The heads of the professorial groups as well as the management of the Faculty must address this issue.

The Faculty places a lot of hope on the newly established Riga Technical University Development Foundation, which should help to upgrade the infrastructure of the Faculty.

Even though doctoral students must be able to read research literature in foreign languages, the issue of publishing and writing academic literature in Latvian remains important. This issue must be addressed constantly.

With the impending entry of Latvia into the European Union, the question of wide discrepancies in the level of remuneration in Latvian and European Universities acquires new urgency. Since the movement of labour in the EU is unrestricted, after the successful completion of doctoral studies young scientists may opt to work abroad. Evidently, this question calls for strategic, national-level solutions.
