Undergraduate Usage of Mobile Phones and Its Implication of School Application

The study is a survey research intended to find out undergraduate usage of mobile phones and its implication of school application. The colloquium population is 27,650 at which two hundred and thirty eight undergraduate students were randomly selected from two universities in the Federal Republic of Nigeria. A questionnaire on “current trends in mobile phone usage among adolescents” was used for the study.  The instrument was validated and tested reliable.  Five research questions were formulated to guide the study.  The researcher as well as ten research assistants personally administered the questionnaire.  The questionnaire forms were collected on the spot and so there was a hundred percent rate of return.  It was discovered that nearly all the undergraduate students own mobile phones and majority consider it very useful.  Several reasons were advanced for owning a mobile phone by students.  These include; for mobility, emergency, e-mails and short message service, self assurance, improved social status, for fashion, loading information, social network and malpractice.  The features commonly used by students apart from  sending and receiving calls is the short message service.  The implications of mobile phone usage by students on school administration are: it is an object of distraction, encourage laziness as students now browse instead of going to the library, an object for examination malpractice and several other vices.  Recommendations were made to check the use of mobile phones by undergraduate students in Nigerian universities.

A validated ontology for meta-level control domain

The main objective of meta-level control is to decide what and how much reasoning to do instead of what actions to do. Meta-level control domain involves a large number of processes and actions with terminology that become confusing. For this reason, an ontology to describe the semantic relationships and hierarchical structure of terms related to metacognition is proposed. The ontology was developed based on definitions found in the literature. Experts validated the ontology using a survey. The validation result indicated that the design of an ontology based on the meta-level control domain allows reusing and sharing knowledge defining a common vocabulary

Rapid Releases and Testing Problems at the industry: A survey

Rapid releases and continuous software development are established practices in modern agile projects. The advantages of them are widely known across the software development community, but there are some studies which mention that there are still challenges to face. According to them, there are different open issues which are affecting the implementation of an adequate testing process. With the aim of validating if these problems are present in real projects, in this paper we present the results of a survey whose goal was to validate whether the industry is experiencing similar issues and their causes. The findings demonstrate that both the industry and academic side are aligned, and that there is still a need for processes and tools regarding the testing process in continuous development.XVI Workshop Ingeniería de Software.Red de Universidades con Carreras en Informátic

Reasoning and Reuse in Software Architecture Design: Practices in the Argentine Industry

Over the last years, software architecture design has gained significant importance in both, industrial and research areas due to its relevance in the software system development process. In this context, special attention has been given to the documentation of architects’ reasoning during an architectural design, highlighting the advantages and disadvantages of this activity. This work intends to present a view of architects’ practices in the Argentine industry regarding reasoning documentation and its subsequent use and access.Fil: Carignano, Maria Celeste.

The Perception of Technical Debt in the Embedded Systems Domain:An Industrial Case Study

Technical Debt Management (TDM) has drawn the attention of software industries during the last years, including embedded systems. However, we currently lack an overview of how practitioners from this application domain perceive technical debt. To this end, we conducted a multiple case study in the embedded systems industry, to investigate: (a) the expected life-time of components that have TD, (b) the most frequently occurring types of TD in them, and (c) the significance of TD against run-time quality attributes. The case study was performed on seven embedded systems industries (telecommunications, printing, smart manufacturing, sensors, etc.) from five countries (Greece, Netherlands, Sweden, Austria, and Finland). The results of the case study suggest that: (a) maintainability is more seriously considered when the expected lifetime of components is larger than ten years, (b) the most frequent types of debt are test, architectural, and code debt, and (c) in embedded systems the run-time qualities are prioritized compared to design-time qualities that are usually associated with TD. The obtained results can be useful for both researchers and practitioners: the former can focus their research on the most industrially-relevant aspects of TD, whereas the latter can be informed about the most common types of TD and how to focus their TDM processes

Exploring software practitioners perceptions and experience in requirements reuse : a survey in Malaysia

In Software Product Lines (SPL) development, reuse process is planned ahead of time, while in traditional software development reuse can occur opportunistically: unplanned or in ad hoc manner. Although many research efforts in SPL focus on issues related to architecture, designs and codes reuse, research on requirements reuse has received slightly less attention from researchers and practitioners. Requirements Reuse (RR) in SPL is the process of systematically reusing previously defined and validated requirements for an earlier software product and applying them to a new and slightly different product within a similar domain. This paper presents a survey pertaining to RR practice that was conducted in Malaysia with two objectives: a) to identify the factors influencing software practitioners in RR, and b) to assess the factors hindering software practitioners from reusing requirements in software development. The survey results have confirmed seven factors that can influence RR practice in Malaysia. The survey results have also revealed three main impediments to RR practice in Malaysia: the unavailability of RR tools or framework to select requirements for reuse, the conditions of existing requirements to be reused (incomplete, poorly structured or not kept updated), and the lack of awareness and RR education among software practitioners pertaining to the systematic R

The Context and Contextual Constructs of Research

This paper presents the Contextual Constructs Model (CCM) and the theory which underpins it, Contextual Constructs Theory (CCT). Developed as part of a complex project designed to investigate user perceptions of Information Quality (IQ) in the context of Web-based Information Retrieval (IR), the CCM is not a single research method per se. Instead, CCT/CCM is a modelled research framework providing an over-arching approach to scientific investigation, by which a researcher is able to identify multiple possible methods of study and analysis according to the identified research constructs and their contexts. Central to CCT is that all research involves the fusion of two key component parts; that of (1) context; and (2) cognitively-driven constructs; and that the co-dependent nature of the relationship between these components inform the research process, development and eventual outcomes. The resulting CCM framework is one which scaffolds research as a contextual process of phases, identifying the conceptual; philosophical, implementation, and evaluation tasks associated with a complex research investigation. The underlying epistemology of such a contextual approach to research is said to be a blend of a critical-real world view within a systems-science approach to investigation
