An actor-network theory (ANT) approach to Turkish e-government gateway initiative

There are various models proposed in the literature to analyze trajectories of e-Government projects in terms of success and failure. Yet, only the Actor-Network Theory (ANT) perspective (Heeks and Stanforth, 2007) considers the interaction factors among network actors and actants. This paper proposes the ANT for approaching to the Turkish e-Government Gateway initiative as a case study. In doing so, it provides valuable insight in terms of both local and global actor-networks which surround the initiative

Mobile phone and e-government in Turkey: practices and technological choices at the cross-road

Enhanced data services through mobile phones are expected to be soon fully transactional and embedded within future mobile consumption practices. While private services will surely continue to take the lead, others such as government and NGOs will become more prominent m-players. It is not yet sure which form of technological standards will take the lead including enhance SMS based operations or Internet based specifically developed mobile phone applications. With the introduction of interactive transactions via mobile phones, currently untapped segment of the populations (without computers) have the potential to be accessed. Our research, as a reflection of the current market situation in an emerging country context, in the case of mobile phones analyzes the current needs or emergence of dependencies regarding the use of m/e-government services from the perspective of municipality officers. We contend that more research is needed to understand current preparatory bottlenecks and front loading activities to be able to encourage future intention to use e-government services through mobile phone technologies. This study highlights and interprets the current emerging practices and praxis for consuming m-government services within government

Indefinite almost paracontact metric manifolds

In this paper we introduce the concept of $(\varepsilon)$-almost paracontact manifolds, and in particular, of $(\varepsilon)$-para Sasakian manifolds. Several examples are presented. Some typical identities for curvature tensor and Ricci tensor of $(\varepsilon)$-para Sasakian manifolds are obtained. We prove that if a semi-Riemannian manifold is one of flat, proper recurrent or proper Ricci-recurrent, then it can not admit an $(\varepsilon)$-para Sasakian structure. We show that, for an $(\varepsilon)$-para Sasakian manifold, the conditions of being symmetric, semi-symmetric or of constant sectional curvature are all identical. It is shown that a symmetric spacelike (resp. timelike) $(\varepsilon)$-para Sasakian manifold $M^{n}$ is locally isometric to a pseudohyperbolic space $H_{\nu}^{n}(1)$ (resp. pseudosphere $S_{\nu}^{n}(1)$). In last, it is proved that for an $(\varepsilon)$-para Sasakian manifold, the conditions of being Ricci-semisymmetric, Ricci-symmetric and Einstein are all identical

M-devlet kullanıcı kabul potansiyeli: kümeleme analizi ve karar ağacı yaklaşımı

M-devlet, e-devletin ardından henüz gelişim safhasındadır. E-devlet hizmetlerinden faydalanmak için vatandaşların bilgisayara ve İnternet erişimine sahip olmaları gerekmektedir. Vatandaşların bilgisayar okur-yazarlık seviyelerinin henüz istenen seviyelere gelmemiş olması e-devlet kullanımının yaygınlaşmasını sınırlamaktadır. Öte yandan, ülkemizdeki cep telefonu cihaz parkına ve kapsama alanlarına bakıldığında, cihaz parkının yeni nesil telefonlardan oluştuğu, erişkin nüfusun önemli kısmının en az bir cep telefonu sahibi olduğu, ülkemizin hızlı ve uygun ücretli 3G Internet hizmetleri ile kapsandığı görülmektedir. Tüm bu bilgiler ışığında, m-devlet yaklaşımının Türkiye için benimsenmesinin önemli avantajları beraberinde getirebileceği düşünülebilir. Bu çalışma, m-devletin Türkiye'de geliştirilmesine yönelik kullanıcı kabulünü inceleyerek, ulusal yazına m-devlet çalışmaları alanında katkı yapmayı amaçlamaktadır

η\eta-Ricci solitons in (ε)(\varepsilon)-almost paracontact metric manifolds

The object of this paper is to study $\eta$-Ricci solitons on $(\varepsilon)$-almost paracontact metric manifolds. We investigate $\eta$-Ricci solitons in the case when its potential vector field is exactly the characteristic vector field $\xi$ of the $(\varepsilon)$-almost paracontact metric manifold and when the potential vector field is torse-forming. We also study Einstein-like and $(\varepsilon)$-para Sasakian manifolds admitting $\eta$-Ricci solitons. Finally we obtain some results for $\eta$-Ricci solitons on $(\varepsilon)$-almost paracontact metric manifolds with a special view towards parallel symmetric (0,2)-tensor fields.Comment: 20 page
