Predicting fault-proneness using OO metrics. An industrial case study

Abstract: Software quality is an important external software attribute that is difficult to measure objectively. In this case study, we empirically validate a set of object-oriented metrics in terms of their usefulness in predicting fault-proneness, an important software quality indicator We use a set of ten software product metrics that relate to the following software attributes: the size of the software, coupling, cohesion, inheritance, and reuse. Eight hypotheses on the correlations of the metrics with fault-proneness are given. These hypotheses are empirically tested in a case study, in which the client side of a large network service management system is studied. The subject system is written in Java and it consists of 123 classes. The validation is carried out using two data analysis techniques: regression analysis and discriminant analysis.

Cholesterol modulates glycolipid conformation and receptor activity

Abstract: We document a new dimension of surface recognition in which communication is controlled through the collective behavior of lipids. Membrane cholesterol induces a tilt in glycolipid receptor headgroup, resulting in loss of access for ligand binding. This property appears to organize erythrocyte blood group presentation and glycolipid receptor function during the activation of sperm fertility, suggesting that lipid 'allostery' is a means to regulate membrane recognition processes.

Content creation challenges and flow experience in educational games: The IT-Emperor case

Abstract: Students increasingly demand more constructive online courses that not only provide information but also facilitate studying experiences. Educational games offer a viable strategy to this end. In this paper, the experiences of university students ( n = 18) playing an educational game, IT-Emperor, which was designed to facilitate flow experience, are studied through questionnaires and interviews. The main purpose of this paper is to study the usefulness of content creation challenges included in IT-Emperor and factors that have an influence on flow experience. Results indicate that half of the participants experienced flow while playing IT-Emperor. This finding is significant because flow tends to have a positive impact on learning. Content creation was reported as the main activity causing flow; bad usability and low gamefulness were cited as obstacles of flow experience. However, because of the small sample size of this study, more research on the topic is recommended.

The Employment Effects of Low-Wage Subsidies

Abstract: Low-wage subsidies are often proposed as a solution to the unemployment problem among the low skilled. Yet the empirical evidence on the effects of low-wage subsidies is surprisingly scarce. This paper examines the employment effects of a Finnish payroll tax subsidy scheme, which is targeted at the employers of older, full-time, low-wage workers. The system’s clear eligibility criteria open up an opportunity for a reliable estimation of the causal impacts of the subsidy, using a difference-in-difference-in-differences approach. Our results indicate that the subsidy system had no effects on the employment rate. However, it appears to have increased the probability of part-time workers obtaining full-time employment.
