Investigation of landslide detection using radial basis functions: a case study of the Taşkent landslide, Turkey
No full textThis paper investigates landslide detection over flat and steep-slope areas with large forest cover using different radial basis function interpolation methods, which can affect the quality of a digital elevation model. Unmanned aerial vehicles have been widely used in landslide detection studies. The generation of image-based point clouds is achievable with various matching algorithms from computer vision systems. Point cloud-based analysis was performed by generating multi-temporal digital elevation models to detect landslide displacement. Interpolation methodology has a crucial task to fill the gaps in insufficient areas that result from filtered areas or sensors that do not generate spatial information. Radial basis function interpolations are the most commonly used technique for estimating the unknown values in survey areas. However, the quality of the radial basis function interpolation methods for landslide studies has not been thoroughly investigated in previous studies. In this study, radial basis function interpolation methods are investigated and compared with the global navigational satellite systems, which provide high accuracy for geodetic measurement systems. The main purpose of this study was to investigate the various radial basis function models to detect landslides using a point cloud-based digital elevation model and determine the quality of detection with global navigational satellite systems. As a result of this study, each of the radial basis function-generated digital elevation models was found to be statistically compatible with global navigational satellite systems, resulting in displacements from the ground truth data
Perspectives on protected area and wildfire management in the Black Sea region
Get PDFProtected areas are necessary for the conservation and enhancement of biodiversity. Wildfires are major threats to forests and other natural areas, because they may cause irreversible damages. The aim of this study was to analyze the perspective of experts (N = 284), from six countries of the Black Sea, on the current status and problems of protected areas and wildfires. Understanding their points of view could enhance future management on these issues in the region. Data collection was carried out for 9 months, using a web-based questionnaire. Wildfires were perceived as a serious problem in Turkey, Armenia and Greece but as a substantially less serious problem in Romania, Ukraine and Moldova. In Greece, Armenia, and especially Ukraine, the current designated protected areas are considered sufficient to maintain biodiversity, while in Romania, Turkey, and especially Moldova, more areas should be designated as protected. A major need in all countries (except for Turkey) is the increased use of information and communication technologies for both wildfire suppression and protected area management. Experts were divided on whether wildfire suppression and management of protected areas are interconnected. However, there is growing awareness of the adverse impacts of climate change in protected areas and the frequency of wildfires in the future. The most frequently suggested measures to alleviate these impacts were: changes in forest management and increasing public awareness for wildfire suppression, along with changes in forest management and increased staff training to enhance protected area conservation.EU INTERREG IV "Black Sea Basin Joint Operational Programme 2007-2013" framework,

Witnessing verbal aggression: role of customers' self-conscious emotions
Get PDFPurpose
This paper aims to examine the widespread effects of service actors' verbal aggression on witness customers' intentions toward the service organizations through their self-conscious emotions. The moderating roles of the witness customers' empathic tendencies and the source of aggression are also examined.
Design/methodology/approach
In two scenario-based experiments and by adopting a multifoci approach, severity of mistreatment (aggression vs incivility vs no-mistreatment) and source of mistreatment (employee-to-employee and customer-to-customer) were manipulated to test distinctive effects of witnessing aggression on self-conscious emotions and intentions.
Findings
This study shows that witnessing aggression during service experiences negatively influences customers' intentions towards the service organization through self-conscious emotions. Moreover, empathic tendencies of customers make these effects more pronounced. It is also shown that witnessing employee-to-employee aggression has a stronger effect on self-conscious emotions and intentions than customer-to-customer aggression.
Originality/value
This paper is one of the first attempts to investigate the distinctive effects of witnessing aggression during service experiences and the roles of self-conscious emotions and emphatic tendencies
Adaptation of the fear of COVİD-19 scale: Its association with psychological distress and life satisfaction in Turkey
Get PDFThe world is currently experiencing a pandemic of an infectious disease called COVID19 which has drawn global intensive attention. While global attention is largely focusing
on the effects of the coronavirus on physical health, the impacts of the coronavirus on
psychological health cannot be overlooked. Therefore, this study aims to adapt the Fear of
COVID-19 Scale into Turkish and investigate the relationships between fear of COVID19, psychological distress, and life satisfaction. Data were collected by convenience
sampling method, which allowed us to reach total 1304 participants, aged between 18
and 64 years, from 75 cities in Turkey. In the adaptation process of the Fear of COVID-19
Scale, confirmatory factor analysis, Item Response Theory, convergent validity, and
reliability (Cronbach’s α, McDonald’s ω, Guttmann’s λ6, and composite reliability)
analyses were performed. Additionally, the mediating role of psychological distress on
the relationship between fear of COVID-19 and life satisfaction was tested. The unidimensionality of the 7-item scale was confirmed on a Turkish sample. Item Response
Theory revealed that all items were coherent and fit with the model. The results indicated
that the Turkish version of the scale had satisfactory reliability coefficients. The fear of
COVID-19 was found to be associated with psychological distress and life satisfaction.
Results indicated that the Turkish version of the Fear of COVID-19 Scale had strong
psychometric properties. This scale will allow mental health professionals to do research
on the psychological impacts of COVID-19 in Turkey
Optimization of triple dye mixture removal by oxidation with Fenton
No full textAzo dyes are widely used in textile industry due to their easy production, high stability during washing and variety of colors.
It raises concern over the ecosystem because of its structural features. Some advanced oxidation process that is tertiary treatment is one of the conventional treatment methods. Pollutants that cannot be removed by primary and secondary treatment
are treated by tertiary treatment methods. Primary and secondary treatment methods are not generally sufcient for removal
of azo dyes. For this reason, it has an important place in its treatment with advanced oxidation processes. The aim of this
study is to investigate the efect of diferent parameters on color and COD removal yields of triple dye mixtures by Fenton
method and to optimize with the Taguchi method. Moreover, the aim is to examine the relationship between these parameters
and ORP by regression analysis, and the change of organic groups by FTIR analysis in the efuent. As a result of the study,
it was observed that the parameters considered had diferent efects on COD and color removal. There was an increase in
both color and COD removal only with the increase in H2O2 concentration. The highest COD and color removal yields were
95.8% and 99.3%, respectively. As a conclusion, Fenton process is a method that can be preferred in the treatment of textile
dyestufs since the chemicals used are non-toxic, abundant and economical, and therefore, the operation cost of the system
is quite favorable, providing advantages to compete with other advanced oxidation processe

The proposed AFSS unit element is consist of a single PIN diode with a simple microstrip patch design which performance characteristics are varies with the state of the diodes. The proposed unit elements have been used to form an array that is placed at the aperture of a double ridge horn antenna. With the variation in state of diodes, the antenna acts as a Filtenna module to filtering the incoming electromagnetic waves in frequency band of 1.8 to 2.8 GHz. From the experimental results, it is shown that the proposed Filtenna achieves a signal attenuation of 7.3 dBi at 2.1 GHz
Türkiye’deki öğrencilerin fen okuryazarlığını etkileyen faktörler nelerdir? PISA 2015 verisine dayalı bir hiyerarşik doğrusal modelleme çalışması
Get PDFThe main purpose of this study is to investigate the student and school-level variables affecting Turkish students' science literacy using PISA 2015 data. In this way, we aim to build a hierarchical model of the variables predicting students' science literacy level. Particularly, when we consider the sharp decrease in Turkish students' success in PISA 2015, the implications of this study would be even stronger. Because of the nested nature of the data and a high intraclass correlation coefficient (ICC) value (0.52), we performed hierarchical linear modeling (HLM) analysis. As a result, we constructed a model including nine student-level and four school-level variables to predict students' science literacy scores. We classified the student-level variables into three categories as personal characteristics, variables associated with learning time, and variables associated with teaching-learning process. Similarly, we classified the school-level variables into two categories: school resources and learning environment in the school. While "weekly science learning time" is the most prominent variable at the student-level, "science specific resources", at the school-level, seems to be the most powerful predictor of students' success. One of the surprising findings in this study is that there is a significant negative correlation between "out-of-school study time" and science literacy scores.The main purpose of this study is to investigate the student and school-level variables affecting Turkish

The effect of goji berry consumption on weight loss in boxers
No full textStudy Objectives: The aim of this study was to examine whether goji berry consumption has an effect on weight loss in boxers. 24 licensed boxing athletes participated in the study. Methods: Athletes were divided into four groups (Group 1: Control group; Group 2: consuming Goji Berry; Group 3: Training group; Group 4: Goji Berry consuming + Training group) by simple random sampling method. Measurements were carried out two times as pre-test and post-test within the scope of the 6-week training program (3 training per week and 75 minutes for each training). The athletes, who subjected to a diet program while spending their periods in clubs, were given goji berry fruit once a day at the same time in the form of 30 g dried fruit. Descriptive statistics (mean and standard deviation) were calculated in the analysis of the data. The percentage of changing body composition of boxing athletes during the test was calculated with the formula "%Delta = (Post-Test - Pre-Test)/Pre-Test x 100". The difference between the body weight percentage changes of the groups was compared with the One-Way ANOVA and Two-Way repeated measures ANOVA was used in the analysis of the variables measured repeatedly (pre-test and post-test) between the groups. The significance level was set at p<0,05 and p<0,01. Results: According to the findings of the research, it was determined that the highest decrease in body mass index, fat mass and visceral fat ratio, and the highest increase in free-fat mass and basal metabolic rate per kg were in the Goji Berry consuming + Training group. Conclusion: As a result, athletes interested in sports included weight category can use goji berry fruit for body weight control and reduction, which can help them achieve body weight loss and/or control
