Privacy relates to issues regarding collection, secure transmission, storage, authorized access, usage, and disclosure of personal information. This information is used for commercial gain by many organizations. Individual privacy concerns significantly affects consumer willingness to engage in electronic commerce over the Internet. The increased use of the Internet and Web for everyday activities is bringing new threats to personal privacy. This chapter assessed various issues related to individual privacy on the Web, growing concerns among the Web users, technologies employed for collecting and protecting information on the Web, privacy-enhancing technologies and the legal provisions to curb the Web privacy. This chapter also reported detailed discussion about Platform for Privacy Preferences (P3P), its structure, present scenario of its implementation and its future success. Global consistency on Internet privacy protection is important to promote the growth of electronic commerce. To protect consumers in a globally consistent manner, legislation, self-regulation, technical solutions and combination solutions are different ways that can be implemented. © 2008, IGI Global.Review Citation - WoS: 1Evolution of the Relationship Between Urban Planning and Urban Infrastructure(Kare Publ, 2018) Sahin, Savas ZaferIn the face of disasters caused by climate change and ecological degradation, the future of cities has become closely interrelated with the sensitive balance between urban planning and urban infrastructure. Integrated sustainable urban planning and management approaches, where the relationship between urban planning and urban infrastructure is re-examined to manage urban risks, manage the capacity of existing infrastructure, and adapt to climate change have been discussed for a long time. Particularly in the last 2 to 3 decades, in various countries and for different reasons, urban planning and urban infrastructure investments have diverged. Under the influence of neo-liberal policies, the urban planning process has often been transformed into a mechanism of re-distributing urban rents via urban projects, and urban infrastructure investments are presented to society as mega projects to help legitimize the effects of this transformation politically. This dissociation results in an inefficient and ineffective use of resources, a negative effect on the urban ecosystem, and an urban daily life that is fragile and disrupted. The development of a framework that re-integrates planning with infrastructure is an inevitable necessity.Article Citation - WoS: 12Skeletonization-based beam finite element models for stochastic bicontinuous materials: Application to simulations of nanoporous gold(Cambridge Univ Press, 2018) Soyarslan, Celal; Argeso, Hakan; Borgmann, SwantjeAn efficient representative volume element generation strategy is developed in modeling nanoporous materials. It uses periodic 3D beam finite element (FE) models derived from skeletonization of spinodal-like stochastic microstructures produced by a leveled random field. To mimic stiffening with agglomeration of the mass at junctions, an increased Young's modulus is assigned to the elements within the junction zone. The effective Young's modulus, Poisson's ratio, and universal anisotropy index are computed. A good agreement of the Young's modulus predictions with those obtained from experimental results for phase volume fractions 0.20 < phi(B) < 0.50 is observed. Moreover, the elastic anisotropy index of the generated beam networks shows sufficient proximity to isotropy. Finally, it is demonstrated that, as compared to the simulation statistics of voxel-FE models, for the beam-FE models over 500-fold computational acceleration with 250-fold less memory requirement is provided.Review Citation - WoS: 57Citation - Scopus: 65Application of Minimum Quantity Lubrication Techniques in Machining Process of Titanium Alloy for Sustainability: a Review(Springer London Ltd, 2019) Osman, Khaled Ali; Unver, Hakki Ozgur; Seker, UlviRecently, the manufacturing sector is increasingly keen to apply sustainability at all levels of sustainability from system to products and processes. At the processes level, cutting fluids (CFs) are among the most unsustainable materials and need to be addressed properly in accordance with three main and decisive aspects, also known as the triple bottom line: ecology, society, and economics. Minimum quantity lubrication (MQL) is a promising technique that minimizes the use of CFs, thus improving sustainability. This paper presents a review of the literature available on the use of the MQL technique during different machining processes involving titanium alloys (Ti-6Al-4V). To carry out the study, four search engines were used to focus on the most cited articles published over a span of 17years from 2000 to 2016. The performance and drawbacks are compiled for each eco-friendly technique: dry, MQL, and cryogenics with combinations of MQL and cryogenics, critically considering machining parameters such as cutting speed, feed rate, and output measures, namely surface roughness, tool life, and cutting temperature. After drawing conclusions from critical evaluation of research body, future research avenues in the field are proposed for the academics and industry.Article Citation - WoS: 68Citation - Scopus: 82The Effect of Uncertainty on Learning in Game-Like Environments(Pergamon-elsevier Science Ltd, 2013) Ozcelik, Erol; Cagiltay, Nergiz Ercil; Ozcelik, Nese SahinConsidering the role of games for educational purposes, there has an increase in interest among educators in applying strategies used in popular games to create more engaging learning environments. Learning is more fun and appealing in digital educational games and, as a result, it may become more effective. However, few research studies have been conducted to establish principles based on empirical research for designing engaging and entertaining games so as to improve learning. One of the essential characteristics of games that has been unexplored in the literature is the concept of uncertainty. This study examines the effect of uncertainty on learning outcomes. In order to better understand this effect on learning, a game-like learning tool was developed to teach a database concept in higher education programs of software engineering. The tool is designed in two versions: one including uncertainty and the other including no uncertainty. The experimental results of this study reveal that uncertainty enhances learning. Uncertainty is found to be positively associated with motivation. As motivation increases, participants tend to spend more time on answering the questions and to have higher accuracy in these questions. (C) 2013 Elsevier Ltd.

Bugüne kadar yapılan araştırmalar, Hollywood filmlerinde Arap imajının olumsuz tasvir edildiğine dair genel bir anlayışı ortaya koymaktadır. Ancak, “Kral için Hologram” filmi Suudi Arabistan’ının ve halkının hem olumsuz hem de olumlu yönlerine odaklanarak daha gerçekçi ve daha az önyargılı bir yaklaşım sergilemektedir. Bu çalışmanın amacı Suudi Arabistan ve halkının bir Hollywood filmi olan “Kral için Hologram” filmindeki temsilini incelemektir. Çalışmada içerik analizi yöntemi kullanılmıştır. Araştırmanın bulguları, filmdeki ülke imajına ilişkin görsellerin toplam süresinin 28.9 dakika olduğunu göstermiştir. Ülkenin politik ve sosyal niteliği ve ülkenin kapasitesi / yeterliğine ilişkin imajlar en yüksek yüzdeye sahip olarak bulunmuştur. Bu sonuç filmlerin ülke imajı için önemli bir iletişim aracı olduğunu göstermektedir.
