Antecedents of cave visitors' revisit intentions in the context of self-determination theory: a case study on Dupnisa Cave visitors in Turkey

Mustafa Murat KIZANLIKLI

Based on self-determination theory as a conceptual framework, the aim of this study is to reveal the relationships amongst cave visitors' experiences, motivation, satisfaction and revisit intention. In order to test the conceptual model designed in line with the objectives of the study, a survey was conducted amongst a sample of 312 visitors to Dupnisa Cave in Turkey. The analysis showed that visitors' motivation and cave experience positively influenced their satisfaction. Moreover, satisfaction has an effect on visitors' revisit intention. This study is one of the first to attempt to reveal ...Более

Assessment of Cd-induced genotoxic damage in Urtica pilulifera L. using RAPD-PCR analysis

İlhan DOĞAN

Plants can be used as biological indicators in assessing the damage done by bioaccumulation of heavy metals and their negative impact on the environment. In the present research, Roman nettle (Urtica pilulifera L.) was employed as a bioindicator for cadmium (Cd) pollution. The comparisons between unexposed and exposed plant samples revealed inhibition of the root growth (∼25.96% and ∼45.92% after treatment with 100 and 200 µmol/L Cd concentrations, respectively), reduction in the total soluble protein quantities (∼53.92% and ∼66.29% after treatment with 100 and 200 µmol/L Cd concentrations, re ...Более

The usability of Juniperus virginiana L. as a biomonitor of heavy metal pollution in Bishkek City, Kyrgyzstan

Zeki SEVEROĞLU | İlhan DOĞAN | Gülbübü KURMANBEKOVA

Uncontrolled and unplanned urbanization and industrialization due to increase of population and rapid industrial development have created severe environmental problems in Kyrgyzstan during the last few decades. In this study, Juniperus virginiana, a dioecious species, was employed in order to make assessment of the heavy metal pollution rate in the area and of the heavy metal pollution impact on the mineral nutrient status of the plant. For this study, leaf (washed and unwashed) and bark samples of J. virginiana, and its co-located soil samples were collected from eight different stations, all ...Более

Multifractality of the Istanbul and Moscow Stock Market Returns

Mehmet BALCILAR

There is a growing awareness among financial researchers that the traditional models of asset returns cannot capture essential time series properties of the current stock return data. We examine commonly used models, such as the autoregressive integrated moving average (ARIMA) and the autoregressive conditional heteroskedasticity (ARCH) family, and show that these models cannot account for the essential characteristics of the real Istanbul Stock Exchange and Moscow Stock Exchange returns. These models often fail, and when they succeed, they do at the cost of an increasing number of parameters ...Более

An investigation on environmental pollution due to essential heavy metals: a prediction model through multilayer perceptrons

İbrahim İlker ÖZYİĞİT

This research is to predict heavy metal levels in plants, particularly in Robinia pseudoacacia L., and soils using an effective artificial intelligence approach with some ecological parameters, thereby significantly eliminating common defects such as high cost and seriously tedious and time-consuming laboratory procedures. In this respect, the artificial neural network (ANN) is employed to estimate the concentrations of essential heavy metals such as Fe, Mn and Ni, depending on the Cu and Zn concentrations of plant and soil samples collected from five different locations. The derived relative ...Более

Comparative analyses of phytochelatin synthase (PCS) genes in higher plants

İbrahim İlker ÖZYİĞİT

Plants employ various defence strategies to ameliorate the effects of heavy metal exposures, leading to re-establishment of metal homeostasis. One of the strategies includes the biosynthesis of main heavy metal detoxifying peptides phytochelatins (PCs) by phytochelatin synthase (PCS). In the present study, 14 PCS homologues were identified in the genomes of 10 selected plants. The size of these PCSs was 452-545 amino acid residues, with characteristic phytochelatin and phytochelatin_C domains. The N-terminal site of the proteins is highly conserved, whereas the C-terminal site is less conserve ...Более

A multi-national validity analysis of the Personal Report of Communication Apprehension (PRCA-24)

Gülzada STANALİYEVA | Bakıtbek ORUNBEKOV

Methodological issues abound when conducting cross-cultural research. In this manuscript we discuss three methodological issues present in many cross-cultural communication studies: lack of geographic diversity, reliability, and validity. To explore these issues the Personal Report of Communication Apprehension (PRCA-24) is assessed. The PRCA-24 serves as an exemplar of a US-designed and -validated measure frequently used outside the US without tests of validity or measurement invariance. In fact, since 1990 less than 10 studies have reported validity results, often citing fit issues. The PRCA ...Более

Polyaniline-coated charcoal ash: a novel high-capacity adsorbent for removal of thiocyanate ions from aqueous solutions

Mehmet KOBYA

Removal of thiocyanate (SCN-), which is widely used in many industrial processes is of concern due to this toxicity. In this work, the potential of polyaniline-coated charcoal ash (PANI-CCA) as a low-cost and efficient adsorbent was evaluated in order to remove thiocyanate ions from aqueous solution. Morphologies and chemical composition of the PANI-CCAhave been examined by using scanning electron microscopy and X-ray fluorescence spectrometry (XRD). Batch experiments were performed to examine the effects of operating conditions such as pH (6.0-10.0), ash dosage (0-0.30 g/50 ml), initial dye c ...Более

Assessment of pollution at the former uranium waste dumpsite near kaji-Say Village/Kyrgyzstan: a genetic and physiological investigation

İbrahim İlker ÖZYİĞİT | Bermet KIDIRALİYEVA | Kadırbay ÇEKİROV | Gülbübü KURMANBEKOVA | Nurzat ŞAYKİYEVA

Kyrgyzstan still suffers from the past practices of radioactive industry operated by the Soviet Union that caused significant impact on ecosystems in this region, especially related with storage of uranium in inadequate conditions. There are at least 50 abandoned sites used as radioactive waste dumps in the country. Due to the pressure of natural and anthropogenic reasons, the structural foundations of mine waste dumps are gradually losing their integrities. Here, particular interest of our research is to reveal current state of radioactive contamination and to make evaluation on the radiologi ...Более

Deciding Heavy Metal Levels in Soil Based on Various Ecological Information through Artificial Intelligence Modeling

İbrahim İlker ÖZYİĞİT

The aim of this paper is to decide on heavy metal levels based on ecological parameters by effectively eliminating common disadvantages such as high cost and serious time-consuming laboratory procedures via an effective artificial intelligence approach. Therefore, this study is hinged on an artificial intelligence technique, ANN, because of its low cost and high accuracy in overcoming the mentioned limitations and obstacles in the determination process of the amounts of elements. The ANNs have thus been employed to determine essential heavy metals, such as Fe, Mn, and Zn depending on Ca, K, an ...Более
