Perceived supervisor and co-worker support for error management: Impact on perceived psychological safety and service recovery performance
(Elsevier, 2014-08)The study examined the influence of perceived supervisor and co-worker support for error management on employees' engagement in service recovery performance. Furthermore, the current work examined the mediating role of ... -
Perceptions of in-service teachers regarding technology integrated English language teaching
(Anadolu University, 2012-01-07)Technology is changing paradigms in education rapidly and teachers are caught unguarded due to lack of professional training in this aspect. This study reflects the perceptions of nine ELT instructors with M.A TEFL degrees ... -
Perceptual processes of children regarding their nearby home environments living in two socially diverse subcommunities
(ASCE, 2022-09-01)Human life that is collective and diverse on the one hand, but complex and chaotic on the other, is largely experienced in metropolitan cities owing to a significant amount of migration. Istanbul can be defined as a city ... -
Performance analysis and optimization of cascaded I2V and V2V VLC links
(IEEE, 2021-09-06)In smart transportation systems, the infrastructures such as traffic lights are expected to transmit different safety messages according to the receptors (i.e., vehicle, pedestrian, platoon, etc.). The focus of this study ... -
Performance analysis and optimization of relay-assisted free space optical communication systems
(2012-07)Free-space optical (FSO) communication has received an increasing attention in recent years with their ability to achieve ultra-high data rates (at the order of multiple gigabits per second) over unlicensed optical spectrum. ... -
Performance analysis and optimization of unipolar OFDM based relay-assisted visible light communications☆☆
