From looking at its conception, it seems especially well-suited to avoid writing redundant and repeating lines of code which appear on different occasions in the program's code. Excerpt out of 98 pages
Mit Unternehmen, die im Auftrag klinische Studien durchführen (Wenngleich die randomisierte kontrollierte Studie (RCT) der Gold-Standard in der Entwicklung und Einführung neuer Medikamente ist, trifft das nicht auf allen anderen medizinischen Gebieten uneingeschränkt zu, und es gibt einige Nachteile und Grenzen der RCTs, die aber mit anderen Studiendesigns ausgeglichen werden können:Eine Studie ohne Randomisierung gilt als „Beobachtungsstudie“, da nicht in die Wahl der Behandlung eingegriffen wird. << /Length 5 0 R /Filter /FlateDecode >> Offering forums, vocabulary trainer and language courses.

Jones: stream Mit einer RCT untersuchten Forscher die Wirksamkeit von Maßnahmen gegen diese Impfmüdigkeit. A set of join points is called a pointcut (like all method calls in a certain class). kontrolliertes Experiment. This code was also very tough to maintain and change, as the calls to these functions were scattered across the rest of the code and one central code change to solve the problem (which is usually one of the main benefits of object-orientation, the encapsulation of functionality) was not possible. It was randomly chosen who had to start with which assignment, but it was made sure that an even number of participants started with each. Die Fahrleistungswirkung von Car-Sharing Organisationen: Ein kontrolliertes Experiment, Internationales Verkehrswesen 49 (1997)/3: 116-119. These are some of the reasons why computer scientists tend to stay away from empirical research (Tichy summarizes 16 excuses used most to avoid experimentation in software engineering in his paper that was already cited above: (Tichy, 1997)).Even the object-oriented approach, which is currently the most used in industry and academics, has not been validated thoroughlyObject-oriented Programming has had an amazing triumphal procession in the past years, both in the academic world as well as in the industrial development practice. kontrolliertes Experiment. Each of these assignments had to be fulfilled using the plain object-oriented approach (as the control language) as well as using only an aspect to solve the same problems. This can make debugging applications crosscut by many aspects a burden or even nearly impossible. It included questions about general programming skills, Java, Eclipse or AspectJ experience and furthermore contained open slots for the participants to fill in any additional experience they had with different programming languages or techniques like logical programming. Im Kontext dieser Arbeit wurde ein kontrolliertes Experiment mit 36 Teilnehmern durchgeführt, um die Performanz von Softwareentwicklern mit einem statischen und einem dynamischen Typsystem anhand gleicher Aufgaben in einer undokumentierten Anwendung zu vergleichen. Benchmarks are commonly used to create results that can be compared directly to other implementations of the same benchmark (as it is done in many hardware tests, where a benchmark program is run on computers with different hardware to make their overall performance or the performance of a single device comparable) or to create template data that represents a threshold which certain devices, tools or methods have to fulfill for quality testing.Unlike case studies, benchmarks or controlled experiments, field studies are implemented in the field, meaning real software projects in the industry and are designed as an accompanying observation of specific factors, processes, behaviors or situations in these projects. The study described in this work was therefore focused on redundant code and repetitive tasks, where the progress can be measured easily in time.All of this sounds like it is a great achievement for the field of software engineering, but as so often in the young computer science, it has still not been tried to strengthen these claims using empirical studies and controlled experiments. They were convinced that it was a controlled experiment. In 1997, Kiczales and his colleagues published the paper (Kiczales, et al., 1997) which introduced aspect-oriented programming as a modified approach on solving specific problems in software development. The last construct in the example is the advice, which represents the code to be executed on certain occasions. In jedem Dorf gab es eine Impfschwester. BasiliSo to make an own bold claim: There is a huge lack of empirical research in software engineering to back up many assumptions that are made about methods and techniques.
This applies to a large part of the software industry, where the time which developers need to finish the software is a critical factor in almost any software project. vorlesungsskript zu statistische methoden im ws 2017/18 prof. dr. walter olbricht stand: 29.01.2018 inhaltsverzeichnis ii The main motivation was to try to back up or falsify the assumption that aspect-orientation decreases the time needed to write redundant code, but in a rather explorative matter, not trying to concentrate on rejecting or hardening one single hypothesis.
