The use of mobile applications for travel booking: impacts of application quality and brand trust Albayrak, Tahir; González-Rodríguez, M. Rosario; Caber, Meltem; Karasakal, Sezer The increasing use of mobile applications by travellers and the high adaption of tourism companies into this new contact and sales platform, made it necessary to comprehensively investigate the mobile application users’ behaviours. This research combines the Stimulus-Organism-Response (S-O-R) framework and Technology Acceptance Model (TAM) to develop a theoretical background in examining travel booking behaviour of mobile application users. The conceptual model suggests that mobile application quality (MAQ) directly affects perceived ease of use (PEOU) and perceived usefulness (PU) which influence the intention to use (IU) mobile applications. Moreover, the offline brand trust (BT) has been hypothesised as a moderator between PEOU and PU’s impacts on IU mobile applications. Analyses results indicated that system and service quality dimensions of MAQ significantly affect IU mobile application via PEOU and PU. Moreover, offline BT had both direct and moderator influences on the formation of IU mobile application. The study findings contributed to the theory in understanding mobile application users’ behaviours and suggested valuable managerial strategies in the m-commerce context.

How to create flow experience during travel: the role of destination attributes Karasakal, Sezer; Albayrak, Tahir Despite numerous studies investigating flow experience in the adventure tourism context, there is a lack of research concentrating on tourists’ flow experience during travel. This study aims to explore the relationships amongst destination attribute perceptions, flow experience (consisting of focus attention, time distortion, and loss of self-consciousness components), and satisfaction variables. By adapting a quantitative research method, 938 data were collected from British, German, and Russian tourists visiting Antalya, Turkey. The study results reveal that destination attribute perceptions significantly affect flow experience components, which influence tourist satisfaction. Theoretical and practical implications of the study findings are discussed, and some recommendations concerning future research are provided.

Investigation of resistance to synthetic pyrethroids in Blattella germanica L., 1767 (Blattodea: Ectobiidae) and Periplaneta americana L., 1758 (Blattodea: Blattidae) populations in Turkey Öz, Emre; Çetin, Hüseyin; Yanıkoğlu, Atila Cockroaches are widespread pests found in many houses and other buildings. They are known as a vector of many agents of disease like bacteria, viruses and fungi. The repeated usage of persistent and non-biodegradable insecticides has caused resistance in most of the cockroach populations. In this research, the resistance levels of five Blattella germanica L., 1767 (Blattodea: Ectobiidae) and five Periplaneta americana L., 1758 (Blattodea: Blattidae) cockroach populations against some synthetic pyrethroid insecticides (deltamethrin, permethrin, alpha-cypermethrin and lambda-cyhalothrin) were determined between 2014 and 2018 in Turkey. The resistance tests were performed by the standard glass jar surface method as recommended by World Health Organization. By exposing the test chemicals of the second and third instar nymphs of the cockroaches for 1 h, the median lethal dose 50% (LD50) values, resistance ratios (RR) and resistance status were specified. The P. americana populations were all susceptible to tested chemicals with resistance ratios between 1 and 2-fold. In B. germanica populations, the toxic effects of tested chemicals were found very low and resistance status was found moderate (RR 7.7-9.0-fold) or high (RR ≥18.5-fold). This research is the most comprehensive study of the resistance status of the cockroaches in Turkey. In order to prevent the resistance to chemicals, the integrated pest management approach should be prioritized and chemical control should be kept at the lowest level.; Hamam böcekleri birçok ev ve yapılarda bulunan yaygın zararlılardır. Bakteriler, virüsler ve mantarlar gibi pek çok hastalık etkeninin vektörü olarak bilinirler. Kalıcı ve biyolojik olarak parçalanmayan insektisitlerin tekrar tekrar kullanılması, hamam böceği popülasyonlarının çoğunda dirence neden olmuştur. Bu araştırmada, 2014-2018 yılları arasında Türkiye’de beş Blattella germanica L., 1767 (Blattodea: Ectobiidae) ve beş Periplaneta americana L., 1758 (Blattodea: Blattidae) hamam böceği popülasyonunun bazı sentetik piretroid insektisitlere (deltamethrin, permethrin, alpha-cypermethrin ve lambda-cyhalothrin) karşı direnç seviyeleri belirlenmiştir. Direnç testleri Dünya Sağlık Örgütü tarafından önerilen standart cam kavanoz yüzey satıh yöntemi ile yapılmıştır. Hamam böceklerinin ikinci ve üçüncü dönem nimfleri bir saat test kimyasallarına maruz bırakılarak LD50 değerleri, direnç katsayıları ve direnç durumları belirlendi. Periplaneta americana popülasyonların tamamı test edilen kimyasallara duyarlıydı ve direnç katsayıları 1 ve 2 kat arasındadır. Blattella germanica popülasyonlarında, test edilen kimyasalların toksik etkisi çok düşüktü ve orta (7,7-9,0 kat) ve yüksek direnç (≥18,5 kat) bulunmuştur. Bu araştırma hamam böceklerinin direnç durumu hakkında Türkiye’de yapılan en kapsamlı çalışmadır. Kimyasallara karşı direnci önlemek için entegre zararlı mücadele yaklaşımına öncelik verilmeli ve kimyasal kontrol en düşük seviyede tutulmalıdır.

Orthogonal frequency division multiplexing with subcarrier gap modulation Jaradat, Ahmad; Hamamreh, Jehad M.; Arslan, Hüseyin A new modulation scheme called orthogonal frequency division multiplexing with subcarrier gap modulation (OFDM-SGM) is proposed. The proposed scheme embeds extra information bits by exploiting the gap between the active subcarriers in each subblock. The proposed scheme differs from the OFDM-index modulation (OFDM-IM), in which information bits are transmitted using the index of active subcarriers. This OFDM-SGM technique provides superior spectral and energy efficiencies compared to the OFDM-IM, particularly when using binary phase-shift keying (BPSK)-like low constellation schemes, that suit the Internet of Things (IoT) applications that have low complexity. The theoretical error performance of the proposed scheme is presented, and the consistency between the theoretically derived error performance and the simulated one is also provided.
