Item Top quality hotel managers' perspectives on smart technologies: an exploratory study(EMERALD GROUP PUBLISHING LTD, 2024) Yağmur, Yenal; Demirel, Altan; Kılıç, Gül DamlaPurposeThe main purpose of the study is to reveal the hotel managers' perspectives strategies, and predictions on smart technologies, and their expectations for current staff and potential staff to be employed in the future.Design/methodology/approachA qualitative research approach was used to reveal the internal perspectives of managers to determine their Smart Tourism (ST) perspectives. With the snowball sampling method, face-to-face interviews were conducted with 16 senior hotel managers working in a 5-star hotel in Antalya. The data obtained were carried out with inductive content analysis and descriptive analysis from qualitative research analysis methods.FindingsIn this study, hotel managers' broad perspectives on ST were discussed in depth and presented comprehensively. Managers' perceptions of smart technologies are classified in terms of aggregate dimensions and themes. Among the most important findings, rapidity/quickness, managing/holistic assessment, standardization, harmony/integration-coordination and experience-memory, defined as the crossroads of total dimensions or the heart of smart technologies, were identified as the most important themes. In addition, Stylos et al. (2021), another important finding is the classification of technologies used in top-quality hotels, based on the conceptual framework for smart technologies presented in the literature.Practical implicationsThe effective and efficient use of technology, its internalization and openness to technology provides important advantages in hotels such as increasing revisits and satisfaction, providing loyalty and reducing costs. Thus, the perceptions, practices, strategies and prediction of senior managers working in high-level hotels about ST provide valuable data to other hotels that want to survive in the competition.Originality/valueFrom a theoretical point of view, this study is valuable in that it deals with the ST perceptions of senior managers with an exploratory research approach. Managerially, the research findings offer valuable contribution about the attitudes, trends, forecasts and expectations of senior managers working in high-level hotels towards ST.Item Xanthos West Agora III: dynastic nele(KOC UNIV SUNA & INAN KIRAC RES CTR MEDITERRANEAN CIVILIZATIONS-AKMED, 2023) Dönmez, Aytaç; Erdoğan, Halil MertNew evidence obtained from excavation of the West Agora of Xanthos indicates that the first functional formation of the area may have taken place around 530-480 BC. This happened just after the founding of the Xanthos Dynasty during the time of the Dynast Kheziga (Kossika) or his son Kuprlli (Kybernis). Our comparisons with the agora of Avsar Tepesi, dated to the Early Classical period, revealed that these areas were a Lycian design. Epigraphic and archaeological evidence suggest that ceremonies for the purpose of ancestor cult, victory celebrations, and worshiping the gods occurred here. In addition, comparisons are made between our results and Oreshko's pairing of acropolis nele, reveals that these two places, called agora and acropolis in Greek inscriptions from the late fifth century BC, may have been identified nele by the Lycians as only one area. It follows that these areas called nele have quite different characteristics from the Greek agora. Therefore, it shows that Lycian nele were only termed agora in translations on the Inscribed Pillar Monument and the Kudalije Sarcophagus. This occurred because of the lack of a more accurate and appropriate synonym for nele in ancient Greek. In addition, considering the early existence of the cult area of agora gods worshiped in the nele, whose sacred and religious function was a priority, it was initially created under the influence of Anatolian culture. However, due to the significant influence of Athens in the Classical period, it became paired with the Greek twelve gods.Item Diurnal variation of essential oil ratio and composition of some basil genotypes(BANGLADESH BOTANICAL SOC, 2022) Aygün, Yusuf Ziya; Eren, Yılmaz; Ertekin, Esra NerminThe change of essential oil ratios and components of five different basil genotypes harvested at different times (00:00, 06:00, 12:00, 18:00) in day was investigated. Plants were grown under the field conditions and essential oils of the plants were extracted by hydro-distillation method. Identification of essential oil components were performed by GC-MS. It was the G5 genotype that had the highest essential oil content in all plant parts, regardless of the time of day. The highest essential oil content (2.8%) was obtained from the dry leaves of the G5 genotype from the sampling made at 18:00. The main components of essential oils were determined as linalool, eucalyptol, trans alpha-bergamotene, methyl cinnamate, alpha-muurolol and eugenol. However, while the ratios of these components differed between genotypes, the changes in time of day were similar for some components. Linalool content tended to increase mostly in the middle of the day. This study indicated that essential oil ratio and components of different basil genotypes significantly differed according to harvesting times in day.Item Utilization of pumice of Burdur region and zeolite of Bigadic-Balikesir region as fine aggregate in construction materials(MADEN TETKIK VE ARAMA GENEL MUDURLUGU-MTA, 2020) Beycan Tatanoğlu, Özge; Koçkal, Niyazi UğurVolcanic originated pumice and zeolite aggregates have low density owing to their considerable porous structure. Porosity is usually correlated with insulation properties. In order to examine the effects of this lightweight aggregates on dead load of structure and insulation properties of standard construction materials, samples were produced by using pumice and zeolite at varying percentages by volume and control samples were manufactured with crushed sand. The samples were exposed to normal (standard) curing, hot water curing and steam curing to observe the effect of different curing regimes on their behavior. Bulk density and thermal conductivity tests were carried out on samples. Both bulk density and thermal conductivity values of the lightweight mortar samples were smaller than those of control sample. Besides, chemical compositions of aggregates and cement, analyses were also performed. Silica content of pumice and zeolite were %54,09 and %75,14 by mass respectively.Item Essential oil content and components in different purple basil genotypes according to the diurnal changes(BANGLADESH BOTANICAL SOC, 2023) Türkmen, Musa; Ertekin, Esra NerminIn the present study the diurnal variations in plant parts of different purple basil genotypes were determined. Three different purple basil genotypes (Arapgir, Piros and Midnight) were used as plant material. Plants were harvested at 06:00, 12:00, 18:00 and 00:00 hrs to determine the diurnal variation within a day at harvesting time. Essential oil ratio among genotypes, harvesting times and parts of plant varied between 0.460.95%, 0.60 to 0.92% and 0.14-1.29%, respectively. Essential oil ratios among the triple interactions were found to range from 0.05 to 2.57%. The major essential oil was linalool in all genotypes. Results showed that the higher essential oil ratio can be obtained from dry flowers of Arapgir genotype harvested at 00:00 and also, Midnight genotype contained higher essential oil content than others.Item Population structure and insecticide resistance status of Tuta absoluta populations from Turkey(JOHN WILEY & SONS LTD, 2021) İnak, Emre; Özdemir, Esengül; Atış, Abdullah Emre; Zelyüt, Filiz Randa; İnak, Arda; Demir, Ünver; Roditakis, EmmanouilBACKGROUND Tuta absoluta is a devastating pest in tomato production areas worldwide. After its first introduction to Turkey in 2009, it quickly became the major pest of tomato-growing areas. Although some biocontrol agents have been used, especially in greenhouses, the main control of T. absoluta relies heavily on chemical insecticides. However, failure in chemical control has often been reported due to resistance development. In this study, we investigated (i) the population structure of 22 T. absoluta populations across Turkey by analysing haplotypes, based on the cytochrome oxidase subunit I gene; (ii) the efficacy of three registered insecticides from different classes (metaflumizone, chlorantraniliprole and spinosad) in real field-greenhouse conditions; and (iii) the geographic distribution of target-site mutations associated with insecticide resistance. RESULTS The efficacy of spinosad was higher than that of chlorantraniliprole and metaflumizone in the greenhouse trials, as documented by the mortality rates obtained, up to 14 days post application. Known resistance mutations in ryanodine receptors (RyR) (i.e. the I4790M/K and G4946E), nicotinic acetylcholine receptors (G275E), acetylcholinesterases (A201S) and voltage-gated sodium channels (F1845Y and V1848I) were found at various frequencies across the populations genotyped. The I4790K diamide resistance mutation in the RyR has been reported for the first time in T. absoluta populations. Although a total of eight haplotypes were found, the overall mean genetic distance was lower than 0.001, indicating the high genetic homogeneity among Turkish T. absoluta populations. CONCLUSION The results will contribute to design area-wide resistance management programs in T. absoluta control in Turkey. However, more monitoring studies are needed to implement evidence-based insecticide resistance management strategies in the frame of integrated pest management.Item Development of EMS-induced mutagenized groundnut population and discovery of point mutations in the ahFAD2 and Ara h 1 genes by TILLING(Japan Oil Chemists Society, 2021) Karaman, Kürşat; Kızıl, Sibel; Başak, Merve; Uzun, Bülent; Yol, EnginReducing allergenicity and increasing oleic content are important goals in groundnut breeding studies. Ara h 1 is a major allergen gene and Delta(12)-fatty-acid desaturase (FAD2) is responsible for converting oleic into linoleic acid. These genes have homoeologues with one copy in each subgenome, identified as Ara h 1.01, Ara h 1.02, ahFAD2A and ahFAD2B in tetraploid groundnut. To alter functional properties of these genes we have generated an Ethyl Methane Sulfonate (EMS) induced mutant population to be used in Targeting Induced Local Lesions in Genomes (TILLING) approach. Seeds were exposed to two EMS concentrations and the germination rates were calculated as 90.1% (1353 plants) for 0.4% and 60.4% (906 plants) for 1.2% EMS concentrations in the M1 generation. Among the 1541 M2 mutants, 768 were analyzed by TILLING using four homoeologous genes. Two heterozygous mutations were identified in the ahFAD2B and ahFAD2A gene regions from 1.2% and 0.4% EMS-treated populations, respectively. The mutation in ahFAD2B resulted in an amino acid change, which was serine to threonine predicted to be tolerated according to SIFT analysis. The other mutation causing amino acid change, glycine to aspartic acid was predicted to affect protein function in ahFAD2A. No mutations were detected in Ara h 1.01 and Ara h 1.02 for both EMS-treatments after sequencing. We estimated the overall mutation rate to be 1 mutation every 2139 kb. The mutation frequencies were also 1/317 kb for ahFAD2A in 0.4% EMS and 1/466 kb for ahFAD2B in 1.2% EMS treatments. The results demonstrated that TILLING is a powerful tool to interfere with gene function in crops and the mutagenized population developed in this study can be used as an efficient reverse genetics tool for groundnut improvement and functional genomics. © 2021 by Japan Oil Chemists’ Society.
