  • A final selection of 40 students was made in early June 2010, and the students instructed to complete IELTS application forms by 24 June 2010 in order to sit the test on 10 July 2010. All students sat for the Test on this date, and the results were provided to the Principal Researcher a fortnight later. The Principal Researcher then invited the students to collect their certificate (referred to as Test 2 scores) in person, at which point they were asked if they would be willing to be interviewed individually to provide feedback on their English language learning and development...

  • Functional testing is a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (not like in white-box testing).[1] Functional testing differs from system testing in that functional testing "verif[ies] a program by checking it against ... design document(s) or specification(s)", while system testing "validate[s] a program by checking it against the published user or system requirements"...

  • Structural Testing is used to verify the static strength, or fatigue strength of a component by applying measured loads to the test item. Testing can be done to failure, to contractual requirements or to validate finite element model predictions. DTB has successfully completed thousands of structural tests on items ranging in size and complexity from simple coupons to entire aircraft. Fatigue Testing is carried out with the objective of determining the relationship between the stress range and the number of times it can be applied before causing failure....

  • SYSTEM DESIGN AND CONSUMER BEHAVIOR IN ELECTRONIC COMMERCE Hanushek cautions: “If the efficiency of our school systems is due to poor incentives for teachers and administrators coupled with poor decisionmaking by consumers, it would be unwise to expect much from programs that seek to strengthen ‘market forces’ in the selection of schools,” (1981, p. 34-35; emphasis added). Moreover, if students’ outcomes depend importantly on the characteristics of their classmates (i.e.

  • What would science be without measurement, and what would social science be without social measurement? Social measurement belongs to the widely accepted and fruitful stream of the empirical-analytic approach. Statistics and research methodology play a central role, and it is difficult to ascertain precisely when it all started in the social sciences. An important subfield of social measurement is the quantification of human behavior—that is, using measurement instruments of which educational and psychological tests are the most prominent representatives.

  • Forty years ago there was hardly a field called ‘behavioral sciences’. In fact, psychology largely was the behavioral sciences, with some help from group theory in sociology and decision- making in economics. Now, of course, psychology has expanded and developed in a myriad of ways, to the point where ‘behavioral sciences’ is often the more useful term. Physiological psychology has become neuroscience, covering areas not previously part of psychology. Decision-making has become decision science, involving people from economics, marketing, and other disciplines.

  • By the middle of the seventeenth century it had come to be understood that the world was enclosed in a sea of air, much as the greater part of it was covered by water. A scientist of the period, Francesco Lana, contended that a lighter-than-air ship could float upon this sea, and he suggested how such a ship might be built. He was unable to put his invention to a practical test, but he saw only one reason why it might not work:

  • In statistical machine translation, a researcher seeks to determine whether some innovation (e.g., a new feature, model, or inference algorithm) improves translation quality in comparison to a baseline system. To answer this question, he runs an experiment to evaluate the behavior of the two systems on held-out data. In this paper, we consider how to make such experiments more statistically reliable.

  • This project concerns building a document parser that can be used as a software engineering tool. A software tester's task frequently involves comparing the behavior of a running system with a document describing the behavior of the system. If a problem is found, it may indicate an update is required to the document, the software system, or both. A tool to generate tests automatically based on documents would be very useful to software engineers, but it requires a document parser which can identify and extract testable conditions in the text. ...

  • Symbolic execution builds predicates that characterize the conditions under which execution paths can be taken and the effect of the execution on program state. Extracting predicates through symbolic execution is the essential bridge from the complexity of program behavior to the simpler and more orderly world of logic. This chapter presents the symbolic execution and proof of properties.

  • Walnut trees shade the streets of Davis, California. They also provide food for the crows that roost near Davis. Crows crack walnuts by dropping them from heights of 5–10 meters or more onto sidewalks, roads, and parking lots. Occasionally they drop walnuts in front of approaching cars, as if using the cars to crush the nuts for them. Do crows intentionally use cars as nutcrackers? Some of the citizens of Davis, as well as some professional biologists (Maple 1974, in Cristol et al.

  • Models are often used to express requirements, and embed both structure and fault information that can help generate test case specifications. Control flow and data flow testing are based on models extracted from program code. Models can also be extracted from specifications and design, allowing us to make use of additional information about intended behavior.

  • The essential characteristics of system testing are that it is comprehensive, based on a specification of observable behavior, and independent of design and implementation decisions. Independence in system testing avoids repeating software design errors in test design. Acceptance testing abandons specifications in favor of users, and measures how the final system meets users' expectations. Regression testing checks for faults introduced during evolution.
