【1】 Investigating Expectation Violations in Mobile Apps
标题：调查移动应用中的预期违规行为
链接：https://arxiv.org/abs/2201.02269
备注：32 pages, 4 figures, 8 tables
摘要：Information technology and software services are pervasive, occupying the
centre of most aspects of contemporary societies. This has given rise to
commonly expected norms and expectations around how such systems should work,
appropriate penalties for violating these expectations, and more importantly,
indicators of how to reduce the consequences of violations and sanctions.
Evidence for expectation violations and ensuing sanctions exists in a range of
portals used by individuals and groups to start new friendships, explore new
ideas, and provide feedback for products and services. Therein lies insights
that could lead to functional socio-technical systems, and general awareness
and anticipations of human actions (and interactions) when using information
technology and software services. However, limited previous work has examined
such artifacts to provide these understandings. To contribute to such
understandings and theoretical advancement we study expectation violations in
mobile apps, considered among the most engaging socio-technical systems. We
used content analysis and expectancy violation theory (EVT) and expectation
confirmation theory (ECT) to explore the evidence and nature of sanctions in
app reviews for a specific domain of apps. Our outcomes show that users respond
to expectation violation with sanctions when their app does not work as
anticipated, developers seem to target specific market niches when providing
services in an app domain, and users within an app domain respond with similar
sanctions. We contribute to the advancement of expectation violation theories,
and we provide practical insights for the mobile app community.
【2】 Source Code Anti-Plagiarism: a C# Implementation using the Routing Approach
标题：源代码反剽窃：使用路由方法的C#实现
链接：https://arxiv.org/abs/2201.02241
摘要：Despite the approaches proposed so far, software plagiarism is still a
problem which has not been solved entirely yet. The approach introduced
throughout this paper is about a source code anti-plagiarism technique which
aims at rendering the source code incomprehensible to a possible plagiarist and
at the same time preventing source code modifications. The proposal is based on
the concept of Router and makes use of both symmetric encryption and
cryptographic hashing functions to provide such guarantees.
【3】 On the Prevalence, Impact, and Evolution of SQL Code Smells in Data-Intensive Systems
标题：SQL代码嗅觉在数据密集型系统中的流行、影响和演变
链接：https://arxiv.org/abs/2201.02215
备注：None
摘要：Code smells indicate software design problems that harm software quality.
Data-intensive systems that frequently access databases often suffer from SQL
code smells besides the traditional smells. While there have been extensive
studies on traditional code smells, recently, there has been a growing interest
in SQL code smells. In this paper, we conduct an empirical study to investigate
the prevalence and evolution of SQL code smells in open-source, data-intensive
systems. We collected 150 projects and examined both traditional and SQL code
smells in these projects. Our investigation delivers several important
findings. First, SQL code smells are indeed prevalent in data-intensive
software systems. Second, SQL code smells have a weak co-occurrence with
traditional code smells. Third, SQL code smells have a weaker association with
bugs than that of traditional code smells. Fourth, SQL code smells are more
likely to be introduced at the beginning of the project lifetime and likely to
be left in the code without a fix, compared to traditional code smells.
Overall, our results show that SQL code smells are indeed prevalent and
persistent in the studied data-intensive software systems. Developers should be
aware of these smells and consider detecting and refactoring SQL code smells
and traditional code smells separately, using dedicated tools.
