    Basaran, Murat Alper/0000-0001-9887-5531WOS: 000457059800002Researches on tourism investigating quality of life have become an important study area for tourism scholars over the last few decades. Thus, focus points have started to evolve from the macro impact of tourism to the micro impact on individuals and their well-being. The aim of this study is to determine factors that have an impact on the perception of quality of life of the residential tourists. To this end, correspondence analysis and log-linear model are employed that visualize the results and reveal significant factors and interactions terms. According to findings, some demographic factors such as gender, duration of living in Alanya and nationality have an impact on quality of life perception of residential tourists. Besides, supportive evidence for adaptation level theory, used for explaining the effects of big life events on quality of life perception, was found

    Self-deployment of mobile underwater acoustic sensor networks for maximized coverage and guaranteed connectivity

    Self-deployment of sensors with maximized coverage in Underwater Acoustic Sensor Networks (UWASNs) is challenging due to difficulty of access to 3-D underwater environments. The problem is further compounded if the connectivity of the final network is desired. One possible approach to this problem is to drop the sensors on the water surface and then move them to certain depths in the water to maximize the 3-0 coverage while maintaining the initial connectivity. In this paper, we propose a fully distributed node deployment scheme for UWASNs which only requires random dropping of sensors on the water surface. The idea is based on determining the connected dominating set (CDS) of the initial network on the surface and then adjust the depths of all neighbors of a particular dominator node (i.e., the backbone of the network) for minimizing the coverage overlaps among them while still keeping the connectivity with the dominator. The process starts with a leader node and spans all the dominators in the network for repositioning them. In addition to depth adjustment, we studied the effects of possible topology alterations due to water mobility caused by several factors such as waves, winds, currents, vortices or random surface effects, on network coverage and connectivity performance. On the one hand the mobility of nodes may help the topology to get stretched in 2-D, which helps to maximize the coverage in 3-0. On the other hand the mobility may cause the network to get partitioned where some of the nodes are disconnected from the rest of the topology. We investigated the best node deployment time where 2-D coverage is maximized and the network is still connected. To simulate the mobility of the sensors, we implemented meandering current mobility model which is one of the existing mobility models for UWASNs that fits our needs. The performance of the proposed approach is validated through simulation. Simulations results indicate that connectivity can be guaranteed regardless of the transmission and sensing range ratio with a coverage very close to a coverage-aware deployment approach

    A Study on Kazakh Academicians' Information Technology Acceptance

    Information technologies (ITs), which have become one of the key enablers of success in educational competitiveness, have made the understanding of user technology acceptance crucial. The failures of IT investment and implementation lead to unwanted organizational outputs. A better understanding of the contributions of the factors determining the individual's intention to use (IU) IT during the acceptance process will help to prevent probable visible and invisible losses. This research attempts to validate a new technology acceptance model (TAM) version extended with the constructs of Subjective Norm (SN) and Facilitating Conditions (FC) in the context of Kazakh Academicians. The results indicate that this variant of extended TAM will be able to facilitate managers to appropriately employ their strategic decisions on the investments and implementations of IT in educational settings while contributing to the technology acceptance research field. On the other hand, the model is open to development for a higher predictive value
