Lower Devonian vertebrate microfossils from Turkey

A small sample of vertebrate fish scales, predominantly those of a thelodont agnathan, the turiniid Turinia sp. cf. T. nachoi, and a few from the acanthodian gnathostome Nostovicina laticristata, have been found in the Lower Devonian Güneyyaka Formation in the Ovacik slice of the Tahtalidağ Nappe north of Alanya (Antalya Unit) in the Antalya region, southwest Anatolia, southern Turkey. The area is considered to have been on the northern Gondwana margin at that time. The fish microfossils support a Lochkovian to possible early Pragian at youngest (Early Devonian) age for the limestone beds, and are amongst the oldest known Turkish vertebrate fossils.

Evaluation of river water quality using multivariate statistics and water quality indices: A case of Göynük canyon (Turkey)

Natural and anthropogenic water pollution caused by heavy metals has become a major problem worldwide. As a result of these processes, many harmful heavy metals are mixed into the water and endanger the environment and human health. Therefore, this study aimed to investigate the hydrogeochemical properties of the stream waters of Göynük Canyon (Göynük Stream), which is located in southern Turkey, an important touristic region of Antalya. A total of 44 water samples were retained to evaluate the geochemical type, heavy metal contamination level, and suitability for drinking and irrigation of Göynük Canyon Stream waters. All samples were analysed by inductively coupled plasma mass spectrometry (ICP-MS), X-ray fluorescence (XRF), and multi-parameter portable water quality assessment.Analysed water samples were found to be of classes II and III in terms of overall water quality. The average hardness level is above the limit values. The results of geochemical analyses showed that the common water types in the region are Mg–Ca–HCO3, Ca–Mg–HCO3, Ca–Mg–HCO3–SO4, and Ca–Mg–HCO3–Cl-water facies. Most of the samples belong to the "rock weathering dominated" region represented in the Gibbs diagram. The hydrogen ion concentration (pH), electrical conductivity (EC), and total dissolved solids (TDS) values vary between respectively 6.5–7.9; 230.4–720.8 μS/cm, and 149–468 mg/L. Cations and anions followed the order Ca2+ > Mg2+ > Na+ > K+ and HCO3− > SO42− > Cl− > F− > NO3−. Heavy metal anomalies in water followed an increasing order: Cu < As < Pb < Ni < Ba < Fe < Cr < Mn < Zn < Sr. These heavy metals showed high index values (Poseidon index (PoS), contamination factor (CF), enrichment factor (EF), geochemical index (Igeo), heavy metals pollution index (HPI), contamination degree (Cd), in some water samples. There is a spatial anomaly in these locations related to limestone and ophiolite. This water can be used for irrigation purposes according to Wilcox, the United States salinity laboratory diagram (USSL), permeability index (PI), Kelly's ratio (KR), and Residual Sodium Carbonate (RSC).

FIRE WEATHER INDEX AND FOREST FIRE DANGER MAPPING: INSIGHTS FROM A CASE STUDY IN ANTALYA - MANAVGAT FOREST, TURKIYE

Abstract. Forest fires in Türkiye, like in other regions, have detrimental effects on wildlife habitats, water quality, air pollution, climate change, and the economy. These fires become particularly concerning during the dry summer months. In 2021, forest fires affected over 150 thousand hectares of land across the country, with the Manavgat district in Antalya province alone witnessing the burning of approximately 60 thousand hectares of forest area. This study aims to assess the applicability and suitability of Fire Weather Index (FWI) data derived from meteorological station data in the Antalya region, as well as EFFIS FWI data generated using satellite-based meteorological information, for fire danger mapping during the Manavgat forest fire that occurred between 28 July and 6 August 2021. Additionally, correlation analyses were performed between the two FWI datasets and other relevant variables, including the difference in Normalized Burn Ratio (dNBR), the difference in Land Surface Temperature (dLST), and Fire Radiative Power (FRP) data detected from MODIS and VIIRS satellites. The results of the correlation analysis indicated that the FWI values obtained using in-situ meteorology station data showed much higher correlations than FWI values obtained from EFFIS, with the highest correlation (73%) observed with dLST data. Consequently, the fire danger map was created using the in-situ meteorological data, given its stronger correlation. The results prominently revealed a widespread high-risk level across the entire Antalya province, with the Manavgat district classified into the "Extreme" and "Very Extreme" FWI classes, emphasizing the critical importance of utilizing in-situ meteorological data for precise fire danger assessments and proactive fire management strategies.

Exploring Forest Fire Dynamics: Fire Danger Mapping in Antalya Region, Türkiye

The Mediterranean region experiences the annual destruction of thousands of hectares due to climatic conditions. This study examines forest fires in Türkiye’s Antalya region, a Mediterranean high-risk area, from 2000 to 2023, analyzing 26 fires that each damaged over 50 hectares. Fire danger maps created from fire weather indexes (FWI) indicated that 85.7% of the analyzed fire areas were categorized within the high to very extreme danger categories. The study evaluated fire danger maps from EFFIS FWI and ERA5 FWI, both derived from meteorological satellite data, for 14 forest fires between 2019 and 2023. With its better spatial resolution, it was found that EFFIS FWI had a higher correlation (0.98) with in situ FWIs. Since FWIs are calculated from temperature and fire moisture subcomponents, the correlations of satellite-based temperature (MODIS Land Surface Temperature—LST) and soil moisture (SMAP) data with FWIs were investigated. The in situ FWI demonstrated a positive correlation of 0.96 with MODIS LST, 0.92 with EFFIS FWI, and 0.93 with ERA5 FWI. The negative correlation between all FWIs and SMAP soil moisture highlighted a strong relationship, with the highest observed in in situ FWI (−0.93) and −0.90 and −0.87 for EFFIS FWI and ERA5 FWI, respectively.

Exploring the Larvicidal and Repellent Potential of Taurus Cedar (Cedrus libani) Tar against the Brown Dog Tick (Rhipicephalus sanguineus sensu lato).

This study investigated the potential acaricidal and repellent effects of tar obtained from the Lebanon cedar (Cedrus libani A. Rich.) against the brown dog tick species Rhipicephalus sanguineus sensu lato Latreille (Acari: Ixodidae). The goal was to find an alternative, safe, and effective way to eliminate ticks. Tar is traditionally extracted from cedar trees in the Antalya region of Türkiye. The composition of the tar is primarily characterized by a diverse mixture of terpenes, with β-himachalene (29.16%), α-atlantone (28.7%), ar-turmerone (8.82%), longifolene-(V4) (6.66%), α-himachalene (5.28%), and β-turmerone (5.12%) emerging as the predominant constituents. The toxic effects of tar on tick larvae were studied through larval immersion tests (LIT), and its repellent activity was evaluated using a new larval repellent activity test (LRAT). The results revealed significant acaricidal effects, with mortality rates of 77.7% and 82.2% for the Konyaalti and Kepez strains of the brown dog tick, respectively, in response to a 1% concentration of tar. LC50 and LC90 values were determined as 0.47% and 1.52% for the Kepez strain and 0.58% and 1.63% for the Konyaalti strain, respectively. When comparing the repellent effect of tar to the widely used synthetic repellent DEET, repellency rates of up to 100% were observed. As a result, this study establishes, for the first time, the larvicidal and repellent effects of C. libani tar on ticks.

Seven ascidian (Tunicata) species from the North Eastern Mediterranean

Members of the tunicates, a subphylum of marine filter-feeder chordates, inhabit all marine and oceanic habitats from the subtidal to the abyssal. Considered the closest relatives to the vertebrates, the tunicates are widely used as model organisms for evo-devo, allorecognition, senescence, and whole-body regeneration studies. However, species boundaries are poorly understood due to the high morphological and genetic plasticity that characterizes many tunicate taxa. Here, we present findings on seven tunicate species (Botrylloides israeliense, Botrylloides sp., Botryllus humilis, Botryllus schlosseri, Symplegma brakenhielmi, Polyclinum constellatum and Didemnum perlucidum) sampled from six Turkish sites at the North Eastern Mediterranean Sea and employed the mitochondrial barcoding marker (COI) for evaluating the relationships among geographically restricted and widely spread ascidian species. Species delimitation was conducted using sequences generated in the current study in addition to sequences obtained from GenBank. General morphological features and colors of colonies were recorded at sampling sites. Then, all Styelidae colonies were attached and cultured on slides in an aquaculture room, enabling the study of other features, such as zooid distributions and sizes, oral tentacle numbers, and life cycles, using stereo and light microscopes. The spicules of formalin-fixed Didemnum perlucidum samples were examined under a light microscope. Then, scientific names were assigned to all species based on the results of the species delimitation and on comparisons of the obtained COI sequences with GenBank sequences. A putative new Botrylloides species (Botrylloides sp.) from the Antalya region was revealed, with a 99% match with the COI gene of another specimen from Saudi Arabia; further waiting for detailed traditional taxonomy.

Biomass Potential of Organic Wastes in Hotels: A Case Study of Antalya

The innovations brought about by globalization have brought along the changes in consumption habits and resource waste with increasing population. Waste, which does not disappear in nature for years, harms our environment and threatens nature with various effects. Food waste, which is described as a global problem, is reaching greater proportions day by day. Today, food waste and losses in hotels have spread over a wide area, especially due to the open buffet option and the large menus that are created more than necessary. In this study, Antalya region, which is one of the most important tourism regions of Turkey, is discussed. The amount of biomass that can be obtained from the organic waste of a five-star hotel in this region has been calculated. Food waste, grass waste and waste oil were taken into consideration as organic waste. The electrical energy that can be produced by using hotel wastes was calculated at the end.

Identification of local camel populations in Turkiye using morphological, genetic, and breeding info.

The aim of this study was to investigate the demographic, morphological, and genetic characteristics of local camel populations reared in the Turkiye provinces of Aydin, Denizli, and Antalya, which have a long history of camel breeding. Although Turkiye has an old history of camel breeding in its historical process, the number of scientific studies aimed at identifying camel populations in Turkiye is almost negligible. In this study, local camel populations in Aydin, Denizli, and Antalya cities of Turkiye were examined in three dimensions as demographic, morphological, and genetic. A face-to-face survey of 117 breeders was used to determine demographic definitions. While the region where local camels were detected the most was determined as Antalya Region with 78.6%, it was determined that 82.6% of the breeders participating in the survey preferred to breed camels due to their docile temperament. Body measurements were made on 45 camels for morphological identification. Moreover, DNA were sampled with oral swabs from 57 camels for phylogenetic analyses using 16 SSR microsatellite loci to identify the genetic structure of local camel populations. The genetic analyses using SSR markers revealed that the camel populations in the Antalya region had a considerably more isolated genetic structure than the Aydin and Denizli populations, and consequently, these populations may be regarded the native camel population.

The mediation model of learning organization, technology acceptance, and service innovation: accommodation purchase managers’ perceptions in Antalya, Turkey: Part II

PurposeThis study aims to analyze the theoretical complexity that underlies purchase managers’ perceptions of their ability to take part in the implementation of a new back-office service strategy.Design/methodology/approachA survey of purchasing department managers in the Antalya (Turkey) region was conducted. The purchasing managers of Antalya’s five-star accommodation businesses comprise the research sample.FindingsWithin the scope of the study, 205 questionnaires were gathered. Factor analysis, correlation and regression analysis were applied to the obtained data. The learning organization (LO) consists of three factors (organization, group/team and individual), service innovation (SI) consists of two factors (employee innovation behavior and new service development) and technology acceptance (TA) consists of four factors (perceived usefulness, perceived ease of use, facilitating situations and social factors), according to the findings of the factor analysis. According to correlation analysis, LO, SI and TA all have positive and significant relationships. The LO has been observed to play an intermediary function in the relationship between TA and SI as a consequence of the analysis that determines the mediation effect.Originality/valueThis study which dealt with the dimensions of SI, TA and LO showed a proposed model which gives a better understanding of how the development of back-office system strategies is affected by LOs.

Carpet Art As A Source of Inspiration in Urban Landscape Design

One of the sources of inspiration used to increase the aesthetic value of a design product is the traditional arts owned by that culture. When the Turkish traditional art is examined, it is seen that the oldest art is the art of carpet. For this reason, Turkish carpet art was used as a means of inspiration in urban landscape designs. The aim of the research is to emphasize the importance of using local and cultural values as inspiration in urban landscape designs and to provide urban landscape design proposals for the preservation and transfer of these values to future generations. In this context, "Dösemealti" carpets belonging to the Antalya region, which have a significant place in terms of traditional carpet art in Turkey, are considered as a source of inspiration in urban landscape design. Thus, the characteristic features of Dösemealti carpets in traditional Turkish carpets are reflected in urban landscape designs.

The study of pilgrimage in aspects of the economy of tourism organization

The relevance of the work. At the beginning of the XXI century, when the service sector becomes a priority, various types of tourism are actively developing. Among them, religious tourism also occupies a worthy place, which, in our opinion, is a promising area of research. All over the world there are a huge number of religious buildings that are distinguished by historical, cultural and sacred and artistic attractiveness. Sacred objects can be visited all year round, regardless of weather conditions, religion, political ambitions and other reasons. Religious tourism as a scientific direction requires a theoretical basis and the development of a methodological base. The purpose of the work is economic analysis of religious tourism as part of tourism system with a special accent on Turkey. One of the most significant findings relates to the efficacy of integrated development plans initiated by the Turkish government for the Antalya region. This rational policy has led to a substantial increase in state revenues from the tourism industry, tallying at USD 33.3 billion in 1987. The study elucidates how the strategic regulation of foreign investment through integrated plans has not only optimized state revenues but also sustainably developed these resort towns into significant tourism hubs. The global pilgrimage tourism economy has been burgeoning as well, with a CAGR of approximately 8% from 2010-2020, reaching a net market valuation of around USD 60 billion. When dissected further, the data reveal that accommodation services constitute about 30% of the total revenue generated, followed by transportation services at 25%, and miscellaneous expenditures covering the remaining 45%. It unambiguously demonstrates that with meticulous planning and strategic investment, pilgrimage tourism has the potential to become a cornerstone in the diversification and enrichment of national and global tourism economies.

Vector-borne Endemic Viral Infection in Antalya Region: Sandfly Fever

Objective: Sandfly fever (SF) is a self-limited vector-related viral infection caused by the SF virus and is spread by phlebotomine sandflies (PSF). Fever, headache, myalgia, arthralgia, loss of appetite, weakness, nausea, and vomiting are the most common symptoms. Laboratory findings include leukopenia, thrombocytopenia, and elevated liver transaminase enzymes. We aimed to examine the demographic, clinical, and laboratory data of patients who were followed with SF diagnosis. Methods: Patients who were followed with SF diagnosis in our hospital between January 2011 and December 2018 were included. The data were obtained retrospectively. Results: A total of 64 patients were included in the study. The mean age was 33.1 ± 9.7(min:19-max:58) years and 35(54.7%) of them were male. Although 53.1% had a history of contact with PSF, 92.2% had a bite mark. 91.6% of the patients were living on the ground and first floor. Fever was the most common symptom in 95.3% of the patients; 89% had myalgia-weakness, 79.6% had a headache, and 50% had a conjunctival rash. Increased transaminase enzyme levels were observed in approximately 93% of the patients. The average of ALT and AST were 284.7 U/L and 243.5 U/L, respectively. Leukopenia was observed in 79.6% (51/64) of them, and thrombocytopenia in 78% (50/64). CK elevation was 54% ratio (35/64). Samples were tested from 19 patients for the serological diagnosis of SF. IgM was positive in 15 (78.9%) of 19 patients and negative in 4(21%) patients. IgG was positive in 10 (52.6%) of 19 patients. Both IgG and IgM were positive in 9 patients. Only IgG positivity was detected in one patient. Conclusion: SF should be considered in patients presenting with complaints such as fever, headache, muscle joint pain, nausea-vomiting, redness in the eyes, leukopenia, thrombocytopenia, elevated transaminase enzyme, CK level, and living in or having a history of travel to subtropical regions, especially during the summer season and a history of PSF contact.

Characterization of Fisheries Violations From the Türkiye's Mediterranean Coasts Within the Scope of Fisheries Law No. 1380

In this study, fisheries violations within the scope of the Turkish Fisheries Law No. 1380 were characterized for the Mediterranean Coasts of Türkiye. For this purpose, by taking into account the frequency and amount of the fines, the patterns of violations in terms of fishing gear, region, season, region-season and fishing gear-season by regions interactions were determined. Data were derived from the Turkish Coast Guard Command’ fisheries surveillance activities during 2014 for areas between coordinates of (36°00’00” N-29°00’00” E) and (36°00’00” N-35°45’00” E). A total of 491 violations against the Fisheries Law No. 1380 were considered. It was determined that the most violations were made by angling (23.22%) and the least by drift nets (0.4%). According to penalties amounts for the 2014, a total of $298,817 administrative fines were imposed. Trawl violations accounted for the highest total administrative fines (48.38%), while the lowest total administrative fines (0.17%) were for violations with drift nets. While the most violations were detected in Antalya region, the highest administrative fine was applied in Adana-Mersin region. According to seasons, there was a decrease in fisheries violations due to closed season measurement for fishing during summer. In terms of administrative fines, the season-region interaction was experienced the most in Adana-Mersin region during winter, and the least in Hatay-Adana region during summer. In season-region interaction, the most violations were observed in Antalya region in spring, while the least in summer in Hatay-Adana region. In interaction related to fishing gear-season by regions, it was determined that the highest number of violations and administrative fines occurred in winter during angling in Adana-Mersin region and in autumn during purse seine fishing in Hatay-Adana region. As a result, in short term, these findings could assist decision-making mechanisms for the effectiveness and efficiency of MCS (Monitoring, Control and Surveillance) system, which is an important part of fisheries management regime. In long term, these findings could also be used in a regional Decision Support System for fishery management with integrating with other elements of fisheries management regime.

Investigation of Opportunities to Improve Erzurum Provincial Greenhouses by Assesing the Greenhouse Operations in Kumluca District, Antalya

Örtü altı yetiştiriciliği; getirisinin yüksek olması, kısa sezonlarda ürünün yetiştirilip tüketime hazır hale gelmesi, üretici açısından maliyetin kısa sürede karşılanması ve ülke ekonomisine sağladığı katkılar nedeniyle; tarla tarımına göre daha çok özen gösterilmesi gereken bir üretim koludur. Örtü altı yetiştiriciliği ve seracılık ülkemizde tüm bölgelerde aynı seviyede gelişim göstermemiştir. Bu çalışmanın amacı; Antalya, Kumluca yöresinde örtü altı yetiştiriciliği için elde edilen bilgiler ışığında Erzurum’da örtü altı yetiştiriciliğin geliştirilebilirliği konusunda değerlendirmeler sunmaktır. Kumluca yöresinin seracılık açısından önemli bir başarı sağlamış olması ve bu konuda elde edilmiş tecrübeler incelendiğinde, Kumluca örtü altı yetiştiriciliğinin Erzurum örtü altı yetiştiriciliğini geliştirmeye dayalı bazı yol gösterici unsurlara sahip olduğu görülmektedir. Erzurum bulguları incelendiğinde hıyar ve domates üretiminin örtü altı yetiştiriciliğinde en çok yetiştirilen ürünler olduğu ve bu açıdan Kumluca bulguları ile örtüştüğü belirlenmiştir. Erzurum’un karasal iklim tipine sahip olması yıllık ısıtma problemlerini ve buna bağlı olarak maliyetleri arttıracağından Kumluca’dan farklı olarak, bakının hesaplanması ve ayrıca ısıtma için jeotermal veya güneş enerjisi gibi alternatiflerin düşünülmesini gerektirmektedir. Erzurum için en önemli unsurlardan birisi olan seraların ısıtılması, Kumluca’da daha çok dondan korunma şeklinde basit sistemler kullanılarak yürütüldüğünden, Erzurum yöresi seracılığının diğer bölgelerle rekabet edememesi konusunda ısıtma maliyetleri en önemli problemdir. Fakat Kumluca bölgesinde dondan korunma amaçlı uygulanan çatı yağmurlama sistemi ve ısı perdeleri gibi yöntemlerin Erzurum’da bahar aylarında kullanılması erkencilik açısından faydalar sağlayacaktır.

3-D numerical constraints for the Triassic mafic igneous system of Antalya (SW Turkey): Magma generation associated with southern Neotethyan slow seafloor spreading

A ~ 400 m thick Middle-Late Triassic volcano-sedimentary succession crops out in a relatively narrow corridor ~75 km long and ~ 25 km wide close to Antalya Gulf, SW Turkey. The volcanic and subvolcanic rocks represent the majority of the succession and are associated with epiclastic breccia, turbiditic sediments as well as chert and limestone layers. The igneous rocks are alkali basalts, with incompatible element content matching the classical HiMU-OIB types. These are considered as the precursors of a rift system that would have later evolved into a mature Neotethyan oceanic system, with emplacement of massive tholeiitic basalt sequences, not recorded in the investigated area.Clinopyroxene-melt thermobarometric constraints indicate the presence of two main magma chambers, one equilibrated at ~7–10 km depth and ~ 1070 °C and the other at ~15–21 km depth and ~ 1300 °C. Based on these estimates, a 3-D finite element modelling has been applied, simulating the presence of ellipsoidal magma chambers at different depths and with variable sizes, applying different boundary loading conditions. The scenario that best fits the distribution of the volcanic rocks assumes the contemporaneous presence of two magma reservoirs. One is shallow, with a size of ~17 × 1.5 × 1.5 km, and the second is deeper, with a size of ~37 × 3 × 3 km. Numerical simulations show maximum 6 m opening and dilation through horizontal plane at the surface during the Permian/Triassic intracontinental rift phases. Morphological constraints of this rift zone, with the presence of massive lava eruptions also as pillow facies, have been simulated with the existence of a slowly opening rift system. In order to produce the voluminous magma batches in the Antalya region, pure extensional tectonic regimes seem insufficient, and the presence of a transtensional regime must have accompanied the tectonic forces during the Triassic intracontinental rifting stage.

Bazı Pikan Ceviz Çeşitlerinin Meyve Özellikleri İle Biyokimyasal İçeriklerinin Belirlenmesi

This study was carried out to determine some fruit properties and biochemical (total oil, fatty acid composition, protein, total phenolic compounds, total antioxidant capacity, total flavonoids) characteristics of different pecan nut cultivars (Burkett, Choctaw, Mahan, Western, Wichita) grown in the Antalya Region (BATEM). It was determined that some fruit properties and biochemical contents of the cultivars used in the study. In the study, it was determined that the shelled fruit weight varied between 7.78 g (Burkett) and 11.40 g (Mahan), kernel weight between 3.45 g (Burkett) and 5.99 g (Mahan), and kernel percentage between 44.2% (Burkett) and 55.6% (Western). The total oil content of the cultivars ranged from 67.70% (Mahan) to 73.95% (Wichita), protein content from 7.45% (Mahan) to 9.76% (Western), total phenolic compounds from 115.29 mg GAE g-1 (Choctaw) to 176.65 mg GAE/g (Burkett), total antioxidant capacity from 201.36 mg TEAC g-1 (Choctaw) to 487.89 mg TEAC g-1 (Burkett), and total flavonoids from 1.84 mg Catechin g-1 (Western) to 2.24 mg Catechin/g (Mahan). In the study, oleic acid was determined as the major fatty acid, and the lowest ratio of unsaturated fatty acids was found in the Wichita cultivar (90.73%), but the highest ratio was determined in the Western cultivar (91.43%).

Eco-assessment of least disturbed areas of the Antalya River basin: application of diatom indices from different ecoregions.

Biomonitoring of least disturbed areas is a crucial issue to accurately assess the ecological status of surface waters and ensure their sustainability. Diatom metrics are important tools for the assessment of environmental conditions of lotic ecosystems to achieve environmental sustainability. The present study was aimed to evaluate the ecological status of least disturbed areas in the Antalya River basin (Turkey) using diatom indices developed from different ecoregion. Diatom species such as Cymbella excisa, Achnanthidium minutissimum, Cocconeis euglypta, and Cocconeis placentula were the most contributing species to the dissimilarity of sampling stations between rainy and dry seasons. The first two axes of canonical correspondence analysis (CCA) elucidated a strong (86%) correlation between diatom taxa and stressors. Results of the Monte Carlo permutation test indicated that total phosphorus (TP), water temperature, Tin (Sn), total organic carbon, zinc, and pH are significantly influential ecological factors on the distribution of diatom taxa among sampling stations. The Spearman correlation rank test indicated that diatom indices had significant positive and negative correlations with TP gradient. Results revealed that diatom indices developed from different ecoregions have different scores for the eco-assessment of similar sampling stations. European diatom indices mostly showed similar behavior in the bioassessment of the ecological status of rivers in the Antalya region compared to the different ecoregion. Among European diatom indices, TIT was more competitive and could give better results in the bio-evaluation of rivers in the Antalya River basin. Using diatom indices developed from different ecoregions may lead to an erroneous assessment of water quality. Accordingly, ecoregional specific diatom metrics are needed to accurately determine the surface water quality.

Is There a Relationship between Empowering Chefs and the Culinary Creativity Process?

ABSTRACT The aim of the study is to determine the relationship between the empowering perceptions of chefs and the processes of creativity. In this context, data were collected by applying the survey technique to the working group of 502 chefs in Antalya Region, which is a study area. Among the data analysis methods, canonical correlation analysis (CCA) used in the examination of the structure between the two variable sets was preferred. Of the four canonical variables obtained as a result of CCA, two variables were found to be significant and the interpretations were made taking into account these two canonical variables. In line with the results obtained, it has been determined that the chefs’ finding their job meaningful, valuing their work, having autonomy, and making their own decisions positively contribute to developing creative ideas, evaluating them, and finding solutions to problems. In addition, recommendations were made to practitioners and researchers.

How do Sentinel-1 SAR images match with the existing maps

Synthetic Aperture Radar (SAR) images are used in several different applications for Remote Sensing purposes. SAR is an imaging sensor that can detect high-resolution ground images under a wide variety of imaging conditions. As SAR is an active system, the data are already acquired with geo-position information. To investigate to verify the image spatial accuracy, a part of the Antalya region of Turkey was selected as test site. The Open Street Map (OSM) and Photogrammetric Digital Map (PDM) data of the area on the Antalya O25 map were used in comparison. First, characteristic common points were selected on the OSM data and the SAR satellite image both. The projected coordinates of these points were calculated with the QGIS software. Normal distribution of the coordinate differences in these data sets were plotted. It was confirmed that the data sets were in normal distribution and standard deviation and 2 * standard deviation values were calculated. The maximum and minimum confidence interval (95%) was determined according to the standard deviation limit values. X and Y coordinate differences were calculated for 49 selected points from both image pairs SAR&OSM and SAR&PDM. Finally, the maximum differences show that the SAR positional accuracy respect to OSM and PSM is below 1 pixel azimuthal resolution.
