[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] ABSTRACT: The most important goal of the software industry is to produce successful product. During the process of production several times the product fails due to lack of proper management. This paper is exploring the role of software engineering courses in computer engineering related branches and then reasons why software developers lack project management in proper software management trainings. Our findings reflect that in majority of computer related branches like computer science, computer engineering, information system engineering there is no place for software project management course. Our findings are based on a survey of course curriculums of computer engineering, computer science and information system engineering courses taught in Turkish universities.
[Show abstract][Hide abstract] ABSTRACT: The qualifications that constitute the employability and identity of graduates are viewed differently by the academic community and the industry. Currently, it is observed for Information Technologies (IT) sector that the demands of the industry are not always satisfied by the perceived standards of the graduates. To provide feedback to the corresponding departments, a survey regarding employer expectations and factors affecting these expectations has been conducted among a number of senior professionals and managers working in the IT sector in Turkey regarding this inconsistency. The employer expectations are considered in two empirical categories as competencies and adequacies. The multiple regression analysis technique has been used to analyze the survey data. Based on the analysis, recommendations are provided to IT departments as well as their students to better fulfill the demands of the industry.

[Show abstract][Hide abstract] ABSTRACT: Over the past few years, green computing has received an increasing amount of attention since it is considered as one of the critical factors for protecting the environment. This study investigates gender diversity in terms of applying Green Information Technology (GIT) based on the differences between significance tests result for males and females. For this purpose, a survey was conducted among IT professionals from public and private sector organizations since GIT is a new concept and these professionals are expected to have more awareness on this issue. Six factors were included in the analyses. Interestingly, the results indicate that gender diversity exists only when individuals intend to purchase new hardware and when considering the type of IT usage.
[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] 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.
[Show abstract][Hide abstract] ABSTRACT: Most of the important decisions are taken at team meetings during software development process (SDP) and the way of thinking of project leader plays an important role in achieving quality objectives at these team meetings. Considering this important issue, this paper investigates the impact of cognitive and socio-demographic factors on manager's simple thinking style towards improving the quality of team meetings in SDP.We have performed experimentations among Information and Communication Technologies' (ICT) senior professionals and managers from government and private sector organizations for this purpose. The hypotheses have been developed under different empirical categories and then statistical analysis techniques have been used to draw inferences. The results indicate that "type of team meetings", "project leader's cognitive characteristics" and "adoption of a cognitive model at team meetings" have statistically significant impact on manager's simple thinking in terms of improving productivity and contribution of team meetings.
[Show abstract][Hide abstract] ABSTRACT: In this paper, we present a new lossless text compression technique which utilizes syllable-based morphology of multi-syllabic languages. The proposed algorithm is designed to partition words into its syllables and then to produce their shorter bit representations for compression. The method has six main components namely source file, filtering unit, syllable unit, compression unit, dictionary file and target file. The number of bits in coding syllables depends on the number of entries in the dictionary file. The proposed algorithm is implemented and tested using 20 different texts of different lengths collected from different fields. The results indicated a compression of up to 43%.
