    ABSTRACT: This study aims to explore the users’ behaviour and acceptance of social media for learning in higher educational institutions with the help of the extended Technology Acceptance Model (TAM). TAM has been extended to investigate how ethical and security awareness of users affect the actual usage of social learning applications. For this purpose, a survey was conducted and the Structural Equation Model approach was utilised to investigate the direct and indirect causal relationships among the constructs in the research model. Interestingly, the findings from the analysis reveal that, except ‘ease of use’, TAM’s core and external constructs are significant predictors of actual behaviour towards using social media for learning.

    ABSTRACT: This paper examines the existence of diversity between public-and private-sector establishments in Green Information Technology (GIT) adoption using the ‘Technology Acceptance Model’ (TAM). In this study, GIT simply refers to using IT in ways that help to reduce environmental impacts, which include using energy more efficiently and reducing waste. The model is extended to include the external variables as subjective norm and the level of GIT awareness. For this purpose, a survey was conducted among professionals from public- and private-sector establishments. The findings suggest the following: (1) Diversity exists among establishments from public- and private-sectors in the influence of the Perceived Ease-of-Use (PEU) on Perceived Usefulness (PU) and on the Attitude Towards Use (ATU); (2) Most of the public-sector professionals have concerns for environmental sustainability in using IT; (3) TAM is an important tool for investigating the specific barriers and facilitators of environmental behavior at work; (4) TAM has a have significant predictive power in public -sector establishments; and (5) TAM is significant for private-sector establishments except the relations between the PEU and PU, and PEU and ATU.

    ABSTRACT: This study reports the findings of a survey concerning the impact of professionals’ selected socio-demographic factors with regard to their online purchasing behaviour in Turkey, since this consumer group plays an important role in adopting new technologies in societies. The survey has been conducted using a ‘face-to-face interview’ approach during an IT event. To keep in line with the available literature, gender, age, education level, income and daily Internet usage, constitute the socio-demographic variants for this study. Five hypotheses were constructed to investigate the nature of the relationship between the socio-demographic factors and the usage of online purchasing. The chi-square method was selected to test the hypotheses. According to the test results, age, income and education level have a significant impact on the online purchasing behaviour of professionals.

    ABSTRACT: The increase in the use of Information Technology (IT) in recent decades has contributed to additional power consumption as well as a potential overuse of scarce resources. Also, IT is quickly surpassing air transportation in terms of its carbon footprint. For these reasons, increased environmental awareness has increased interest in Green Information Technology (GIT) among IT practitioners. Therefore, the aim of this paper is to investigate behavior for the adoption of GIT applying the conceptual model, referred to as the ‘Theory of Reasoned Action’ (TRA). For this purpose, a survey was conducted among IT professionals from major public and private sector establishments. Findings indicated that behavioral intention influences actual behavior positively. IT professionals with positive intentions towards GIT issues are actually practicing GIT in their work. Results also indicated that external factors such as person related beliefs, sector of respondents’ establishment, and level of awareness have significant impact on attitude towards adoption of GIT.

    ABSTRACT: According to the existing literature, the determinants of environmental attitudes and behavior are important. In this paper impact of information technology adoption environment has been investigated. Some of the studies have successfully utilized Theory of Planned Behavior (TPB) for adoption behavior. This study proposed TPB to ex-plain IT professionals' intentions for Green Information Technology (GIT) practices. For this purpose, a survey was conducted among IT professionals from public and private sector organizations. Core factors of TPB were included in the analysis. Overall, results revealed that the TPB model explains behavioral intent, and all four core constructs were significant predictors of the intent. Limitations of the study, and implications for theory are also discussed. Streszczenie Według wskazań literaturowych, determinanty ekologicznych postaw i zachowań odgrywają istotną rolę w ich kształtowaniu i warto badać wpływ, jaki wywierać może na nie stosowanie technologii informatycznych. W tej pracy wykorzystano teorię planowanego zachowania (Theory of Planned Behavior – TPB), aby wyjaśnić podej-ście profesjonalistów z zakresu IT do praktyk związanych ze stosowaniem zielonych technologii informatycznych (Green Information Technologies – GIT). Badania wśród pracowników IT przeprowadzono w firmach reprezen-tujących dwa sektory: państwowym i prywatnym. Otrzymane wyniki pokazały, że model TPB, uwzględniający cztery filary, wyjaśnia determinanty odnoszące się do zachowania. W artykule omówiono także napotkane ogra-niczenia, a także implikacje dla teorii TPB, które z przeprowadzonych badań wynikają. Słowa kluczowe: Teoria planowanego zachowania, zrównoważoność, zielone technologie informatyczne, profe-sjonaliści z zakresu IT, ANOVA

    ABSTRACT: Quality of software is one of the most critical concerns in software system development, and many products fail to meet the quality objectives when constructed initially. Software quality is highly affected by the development process's actual dynamics. This article proposes the use of the Markov decision process (MDP) for the assessment of software quality because MDP is a useful technique to abstract the model of dynamics of the development process and to test its impact on quality. Additionally, the MDP modeling of the dynamics leads to early prediction of the quality, from the design phases all the way through the different stages of development. The proposed approach is based on the stochastic nature of the software development process, including project architecture, construction strategy of Software Quality Assurance system, its qualification actions, and team assignment strategy. It accepts these factors as inputs, generating a relative quality degree as an output. The proposed approach has been demonstrated for the design phase with a case study taken from the literature. The results prove its robustness and capability to identify appropriate policies in terms of quality, cost, and time. © 2011 Wiley Periodicals, Inc.

    ABSTRACT: Meetings are at the heart of the software development process (SDP) and can be of different types. The present article first proposes an abstract cognitive model for meetings, which represents how different types of meetings are affected by cognitive activities at different stages within the SDP. Second, and based on the analysis of meetings at different stages of SDP, it proposes the removal of such meetings from some of the stages within the program by using a cognitive evaluation model for meetings and their replacement, instead, with information and communication technology tools and techniques by means of a cognitive evaluation model. The abstract cognitive model and the evaluation model are validated empirically through experimentation, carried out through a detailed analysis of a target group composed of information technology professionals. © 2011 Wiley Periodicals, Inc.

    ABSTRACT: JAVA is one of the favorite languages amongst software developers. However, the numbers of specific software metrics to evaluate the JAVA code are limited. In this paper, we evaluate the applicability of a recently developed multi paradigm metric to JAVA projects. The experimentations show that the Multi paradigm metric is an effective measure for estimating the complexity of the JAVA code/projects, and therefore it can be used for controlling the quality of the projects. We have also evaluated the multi-paradigm metric against the principles of measurement theory.

    ABSTRACT: This study proposes a framework for the evaluation and validation of software complexity measure. This framework is designed to analyse whether or not software metric qualifies as a measure from different perspectives. Unlike existing frameworks, it takes into account the practical usefulness of the measure and includes all the factors that are important for theoretical and empirical validation including measurement theory. The applicability of the framework is tested by using cognitive functional size measure. The testing process shows that in the same manner the proposed framework can be applied to any software measure. A comparative study with other frameworks has also been performed. The results reflect that the present framework is a better representation of most of the parameters that are required to evaluate and validate a new complexity measure.

    ABSTRACT: Simple thinking (or simplicity) is a way of coping with complexity. It is especially important in the software development process (SDP), which is an error-prone, time-consuming, and complex activity. This article investigates the role of the thinking style—namely, simple thinking—which has been found effective in solving complicated problems during software development. For this purpose, it reviews and discusses simplicity issues from a general perspective and, then, reports the findings of a survey concerning the assessment of simplicity in SDP. The survey was conducted among information and communication technologies senior professionals and managers from government and private-sector organizations. Relevant hypotheses have been developed under different empirical categories for analysis. Statistical analysis techniques were then used to draw inferences based on these hypotheses. The results have proved simplicity to have a significant role in the SDP to a certain extent. © 2011 Wiley Periodicals, Inc.

    ABSTRACT: Software metrics should be used in order to improve the productivity and quality of software, because they provide critical information about reliability and maintainability of the system. In this paper, we propose a cognitive complexity metric for evaluating design of object-oriented (OO) code. The proposed metric is based on an important feature of the OO systems: Inheritance. It calculates the complexity at method level considering internal structure of methods, and also considers inheritance to calculate the complexity of class hierarchies. The proposed metric is validated both theoretically and empirically. For theoretical validation, principles of measurement theory are applied since the measurement theory has been proposed and extensively used in the literature as a means to evaluate the software engineering metrics. We applied our metric on a real project for empirical validation and compared it with Chidamber and Kemerer (CK) metrics suite. The theoretical, practical and empirical validations and the comparative study prove the robustness of the measure.
