El-Gazzar, Rania; Wahid, Fathul
Cloud computing (CC) offers a new information technology service model for organizations. In spite of its possible
benefits, however, it also poses some serious concerns. Why do organizations adopt CC in spite of its potential risks? Based
on several core concepts based on institutional theory, we propose an analytical framework to better understand the
adoption of CC by organizations. We focus on the concepts of field-level changes, organizational fields, institutional
isomorphism, and institutional strategic responses within the context of CC adoption. We identify a number of
organizations that form the organizational field and bring about changes (i.e., CC providers, peer organizations, business
partners, professional and industry associations, and regulators) that may trigger institutional pressures (i.e., coercive,
normative, and mimetic) on the adopting organizations. We conclude by presenting possible strategic responses (i.e.,
acquiescence, compromise, avoidance, defiance, and manipulation) to address the institutional pressures related to CC
adoption.

One of the robust texture feature extraction methods is Local Binary Pattern (LBP). LBP is a simple but efficient method and gray-scale invariant. Some studies have been proposed to improve the performance of LBP, such as Completed Robust Local Binary Pattern (CRLBP). CPLBP is proposed by Zhao to overcome the weaknesses of CLBP that is sensitive to noise. However, CRLBP is not invariant to rotation. From that problem, in this study, a new approach method of CRLBP is proposed, that proposed method is called Improved Completed Robust Local Binaty Pattterh (ICRLBP), in lCRLBP algorithm, CRLBP algorithm will be inserted by LBPROT algorithm. LBPROT is one of improved LĔP methods that proposed to overcome the LBP weakness which is not rotation invariant. Inserting LBPROT into CRLBP is simpty carried out by shifting the binary value obtained from CRLBP to get the smallest integer value. The performance of ICRLBP is evaluated in content-based image retrieval system using 4 datasets, namely Batik, Tektile, Brodatz, and Corel datasets. The result experiments shaw that the average of precision, recall, and speed of ICRLBP using Modified Canberra distance and M_C feature increased by 14.28%, 13.52%, and 3 times, respectively. Whereas, the average of precision, recall, and speed of ICRLBP using L1 distance and S_M_C feature increasĕd by 21.14%, 20.03%, and 56 times, respectivety, It show that ICRLBP is proven can improve the performance of CRLBP.

Dini, Alfatika Aunuriella; Wahid, Fathul; Sæbo, Øystein
In this study, we explore social media use by politicians by investigating affordances, effects and associated constraints of introducing social media within eParticipation. Based on an interpretive case study in the Indonesian context, involving members of both national and provincial parliament, this study unearths internal and external affordances offered by social media. Internally, among politicians, social media enable, for example, idea storming and information sharing; while externally in the relation with their constituents, social media is used, for instance, for opinion gathering and political networking. These affordances yield both internal and external effects, such as broadened perspective, improved internal political supports, better public control, and better information for decision-making. This study also unveils constraints that hinder politicians in utilizing possibilities offered by social media in the eParticipation context. Theoretical contributions and practical implication are also presented, including classification of internal and external social media affordance, identification of constraints and affordance effects. This study is adding contribution to practice by helping politicians to design social media strategy for eParticipation.

Hamzah, Almed; Wahid, Fathul
This study aims to reexamine some traditional usability principles in the context of social media. The instrument was based on 14 items of usability dimensions (i.e. learnability, flexibility, and robustness) proposed by Dix et al. [1], we employed exploratory factor analysis (EFA) to contextualize them into the suitability of social media usability. Using 54 responses from active users of Facebook and Twitter, this study revealed five new usability dimensions of social media: interactivity, intuitiveness, conformability, adaptability, and forgiveness. The findings substantiate some claims that usability is context-specific: culturally variant and dependent upon the product under examination.
