A Nonlinear Panel ARDL Analysis of Pollution Haven/Halo Hypothesis

Zamira ÖSKÖNBAYEVA

There is a growing popularity for the nonlinear econometric approaches, since linkages among variables are not always linear. Nonlinear approaches provide a broader range of knowledge compared to the linear model. This research aims to assess the impact of foreign direct investment on pollution. To capture the potential asymmetries resulting from rise and fall in the foreign direct investments, the nonlinear panel autoregressive distributed lag approach is employed. In the empirical analysis, annual data of selected 22 transition economies from 1995 to 2016 is utilized. The findings highlighte ...More

Analysis of Article Methodologies on Financial Statements’ Transparency Between the Years 2000 and 2016

Bilal SOLAK

Accounting scandals that took place in the last quarter of the twentieth century such as the one at ENRON and PARMALAT prove the importance of transparency and objectivity for the presentation of financial statements. Accounting researchers all over Turkey and other countries have started to publish more studies using different kinds of methodologies on providing transparency for the financial statements due to the scandals. Published work by accounting scientists is extraordinarily crucial both for accounting theory and shaping accounting applications. In this research, article methodologies ...More

Arsenic Removal by Electrocoagulation

Mehmet KOBYA

Because of the toxic impacts on human health, the arsenic (As) limit value in drinking water was decreased from 50 to 10 μg l −1 by the relevant authorities (WHO 1993; US EPA 2001). In this case, the problem of As pollution in natural water resources used for drinking water has grown even more and turned into a global crisis. According to reports in many parts of the world, over about 230 million people appear to be affected by high arsenic concentrations in groundwater. In this case, it turned out that there was a great need for cost-effective and environmentally friendly technologies from dr ...More

Nazgül İMANBERDİYEVA

This investigation enlightens the original data on the ecological situation of Makmal Valley and neighboring villages Makmal and Chetbulak Toguz-Toro in “Makmalzoloto” gold mining area in Kyrgyzstan. The study was undertaken to put forward the possibilities for preservation of rich biodiversity and ecological state in these villages. The area is under pressure from the activities of gold extraction. Even today environmental pollution and high levels of radiation are observed. The extraction activity has seriously damaged and produced a negative impact on pastures, livestock, as well as biodive ...More

E-Government Development in the Central Asian States: Best Practices, Challenges and Lessons Learned

Ulan BRİMKULOV | Kasım BARIKTABASOV

Many states of the world are developing e-government to raise operating efficiency, better service delivery to citizens, and reduce corruption. But successful development of e-government depends on many factors, such as the level of economic development, the development level of the Information and Communications Technology (ICT) infrastructure, the ICT literacy of citizens, legal framework, political leadership etc. This chapter attempts to confirm this statement using the example of the Central Asian states. The chapter also describes best practices, main challenges and obstacles, and lesson ...More

Introduction to Linear Difference Equations

Anarkül URDALETOVA

One of the biggest problems of modern mathematics is, to a large extent, its isolation from the world around it. Extensive use of linear difference equations can make a great contribution to solving this problem. In the language of these equations, the problems of financial mathematics are beautifully presented. And as can be understood from the study of difference equations, this is by no means their only advantage. In particular, there is a direct connection between the theory of linear difference equations and the theory of linear ordinary differential equations. Therefore, we are convinced ...More

Potential Impacts of Climate Change on Plant Diversity of Sary-Chelek Biosphere Reserve in Kyrgyzstan

Nazgül İMANBERDİYEVA | Zeki SEVEROĞLU

The Sary-Chelek Nature Reserve established in 1959 with an area of 239 km2 and declared as a UNESCO-MAB Biosphere Reserve in 1978 is located on the southeast-facing slope of the northern Chatkal Range in central Jalalabad province. It is centered around the scenic Sary-Chelek Lake. The mountains immediately surrounding the lake abound in exceptionally diverse flora and fauna, what may be the widest variety found in the Tian Shan. The area is spread over varied ecosystems and habitats, which include the forests of spruce and juniper together with the forests of wild fruits and nuts and riparian ...More

Streptomyces bio-products against apple and pear diseases in organic orchards

Tinatin DOOLOTKELDİEVA

Erwinia amylovora as a fire blight pathogen and Venturia inaequalis as a scab pathogen were isolated from the blossoms, exudates, infected fruits, leaves and bent branches of diseased apple, pear and hawthorn trees, selected in the Chy, Osh and Jalal Abad regions. Biochemical and pathogenicity tests, alongside PCR analyses were conducted to identify the local isolates of Erwinia amylovora and Venturia inaequalis. The alternative antagonistic microorganisms which combat bacterium E. amylovora and fungus Venturia inaequalis were tested within in vitro and in vivo conditions. The results revealed ...More

The Effects of Postharvest MAP and Edible Surface Coating (Peppermint Essential Oil) on Fruit Quality and Storage Time in Fig (Ficus carica L.) Fruit Types

Mürüvvet ILGIN

In this study, Abbas fig variety grown in Kahramanmaraş province of Turkey was used.Abbas fig variety was covered with peppermint oil, an essential oil variety, and stored at 4°C for 5 weeks in bags prepared with modified atmosphere packaging (MAP) technology. As a result of the study, it was aimed to extend the storage time and shelf life of the fig fruit with these applications. Pomological and chemical analyses were performed on the samples during storage.In the study, in order to determine fruit quality characteristics, weight loss, fruit width and fruit length, fruit rind and flesh color, ...More
