It Is Expensive to Be Poor: Equity in Financing Education in Turkey (2004–2012)

Turkish government, under the rule of Justice and Development Party (Turkish: Adalet ve Kalkınma Partisi, AKP), (2002-2017) has conducted many educational reforms. Different researchers have evaluated effectiveness of those policies differently. Some claim that policies result in a more inclusive and diverse educational system, others argue that the reforms would rekindle child labor, increase child brides and condemn girls to illiteracy. In our research we measure the effects of educational reforms on equity in financing education (i.e., out-of-pocket expenditures). After estimating Gini, Concentration and Kakwani indices, and graphing Lorenz and Concentration curves, we find out that education financing in Turkey is regressive. Since the year of 2004 there have been no significant improvements: neither in the income equality levels, nor in the distribution of education financing. The poorest quintiles have the highest shares of education expenditure, and the high school education is the most inequitable. Our results conflict with the claim that Turkey became more accessible to poor and the education policies have decreased the inequality

The population of Carassius gibelio (Bloch, 1782) and its parasites in Madatapa Lake (South Georgia)

Gibel carp is a very successful invasive fish species in the waters of Georgian inland and the only fish species in Lake Madatapa. However, almost nothing is known about its biology and morpho-ecological peculiarities at the national level and even the distribution data is not documented. For the first time, we studied the population characteristics of gibel carp in Lake Madatapa (South Georgia) with the aim to reveal the extent of its morphological variability, sex ratio, length-weight relationship and its parasitic community. We showed that the gibel carp population in Madatapa Lake has typical morphological characteristics. The sex ratio is significantly female biased (1/1.8) and the length-weight relationship is within the published margins. The gibel carp population is under the heavy parasitic load, but only two parasitic species (one cestoda and the other digenean species) affect the fishes. Within the framework of the obtained results, we discussed future research needs concerning the gibel carp in the lake

Challenges Students Face during Translation

Translation dates back to centuries. Humans started to translate since the appearance of the written literature. It was the main means to be introduced to foreign culture, literature, achievements in different fields of science. What is translation? There are different answers to this question. Translation is understood as the communication of meaning from one language (the source) to another language (the target), or as the transmittal of written text from one language into another. The terms translation and interpretation are often used interchangeably, with translation referring to the written language and interpretation to the spoken word. Translation is viewed as a process and a product. The article looks at some challenges Georgian students face in the course “Theory and Practice of Translation”

Comparison of Earthworm (Lumbricidae) and Oribatid Mite (Acari, Oribatida) Communities in Natural and Urban Ecosystems

This study investigates earthworm and oribatid mite communities in urban, semi-natural and natural ecosystems of Tbilisi (Georgia). Ten species of earthworms and 100 species of oribatid mites were registered in 45 soil samples. Two species of oribatid mites, Microzetes auxilaris Grandjean, 1936 and Multioppia laniseta Moritz, 1966, are new for the Caucasian fauna. We hypothesized that species number and abundance of invertebrate animals tend to decrease from natural to urban ecosystems. The hypothesis was supported only partially. Number of species of oribatid mites and earthworms decreased together with increase of urbanization, whereas abundance showed no significant changes due to high density of stress tolerant and ubiquitous species in urban sites. Accordingly, species abundance is considered to have minor indicatory value. Our studies support ecological “time-hypothesis” in a way that older (natural) sites were presented with more diverse fauna than recent (urban) ones. Statistical analyses showed that studied ecosystems should be grouped in two rather than three categories: in urban and natural ones.В статье предоставлены результаты исследования сообществ дождевых червей и панцирных клещей в урбанизированных, полуприродных и природных экосистемах г. Тбилиси (Грузия). В 45 почвенных пробах были найдены 10 видов дождевых червей и 100 видов панцирных клещей. Два вида клещей Microzetes auxilaris Grandjean, 1936 и Multioppia laniseta Moritz, 1966 являются новымы для фауны Кавказа. Мы предположили, что количество и плотность населения безпозвоночных должны уменьшаться от природных к урбанизированным экосистемам. Наша гипотеза подтвердилась частично. Количество видов дождевых червей и панцирных клещей сократилось с увеличением степени урбанизированности среды, тогда, как плотность населения существенно не менялась из-за высокой плотности отдельных убиквистовых и толерантных к стрессам видов. Соответственно считаем, что плотность населения не имеет большого индикационного значения. Наши результаты подтверждают экологическую «гипотезу времени» тем, что более старые (природные) участки были представлены более разнообразной фауной, чем более новые (урбанизированные). Статистический анализ показал, что изученные экосистемы должны быть сгруппированны по двум, а не по трем категориям: по природным и урбанизированным

Land use and soil characteristics affect soil organisms differently from above-ground assemblages

Background: Land-use is a major driver of changes in biodiversity worldwide, but studies have overwhelmingly focused on above-ground taxa: the effects on soil biodiversity are less well known, despite the importance of soil organisms in ecosystem functioning. We modelled data from a global biodiversity database to compare how the abundance of soil-dwelling and above-ground organisms responded to land use and soil properties. Results: We found that land use affects overall abundance differently in soil and above-ground assemblages. The abundance of soil organisms was markedly lower in cropland and plantation habitats than in primary vegetation and pasture. Soil properties influenced the abundance of soil biota in ways that differed among land uses, suggesting they shape both abundance and its response to land use. Conclusions: Our results caution against assuming models or indicators derived from above-ground data can apply to soil assemblages and highlight the potential value of incorporating soil properties into biodiversity models

The place of millet in food globalization during Late Prehistory as evidenced by new bioarchaeological data from the Caucasus

Two millets, Panicum miliaceum and Setaria italica, were domesticated in northern China, around 6000 BC. Although its oldest evidence is in Asia, possible independent domestication of these species in the Caucasus has often been proposed. To verify this hypothesis, a multiproxy research program (Orimil) was designed to detect the first evidence of millet in this region. It included a critical review of the occurrence of archaeological millet in the Caucasus, up to Antiquity; isotopic analyses of human and animal bones and charred grains; and radiocarbon dating of millet grains from archaeological contexts dated from the Early Bronze Age (3500–2500 BC) to the 1st Century BC. The results show that these two cereals were cultivated during the Middle Bronze Age (MBA), around 2000–1800 BC, especially Setaria italica which is the most ancient millet found in Georgia. Isotopic analyses also show a significant enrichment in 13C in human and animal tissues, indicating an increasing C4 plants consumption at the same period. More broadly, our results assert that millet was not present in the Caucasus in the Neolithic period. Its arrival in the region, based on existing data in Eurasia, was from the south, without excluding a possible local domestication of Setaria italica

Global monitoring of soil animal communities using a common methodology.

Here we introduce the Soil BON Foodweb Team, a cross-continental collaborative network that aims to monitor soil animal communities and food webs using consistent methodology at a global scale. Soil animals support vital soil processes via soil structure modification, consumption of dead organic matter, and interactions with microbial and plant communities. Soil animal effects on ecosystem functions have been demonstrated by correlative analyses as well as in laboratory and field experiments, but these studies typically focus on selected animal groups or species at one or few sites with limited variation in environmental conditions. The lack of comprehensive harmonised large-scale soil animal community data including microfauna, mesofauna, and macrofauna, in conjunction with related soil functions, microbial communities, and vegetation, limits our understanding of biological interactions in soil systems and how these interactions affect ecosystem functioning. To provide such data, the Soil BON Foodweb Team invites researchers worldwide to use a common methodology to address six long-term goals: (1) to collect globally representative harmonised data on soil micro-, meso-, and macrofauna communities, (2) to describe key environmental drivers of soil animal communities and food webs, (3) to assess the efficiency of conservation approaches for the protection of soil animal communities, (4) to describe soil food webs and their association with soil functioning globally, (5) to establish a global research network for soil biodiversity monitoring and collaborative projects in related topics, (6) to reinforce local collaboration networks and expertise and support capacity building for soil animal research around the world. In this paper, we describe the vision of the global research network and the common sampling protocol to assess soil animal communities and advocate for the use of standard methodologies across observational and experimental soil animal studies. We will use this protocol to conduct soil animal assessments and reconstruct soil food webs at sites associated with the global soil biodiversity monitoring network, Soil BON, allowing us to assess linkages among soil biodiversity, vegetation, soil physico-chemical properties, climate, and ecosystem functions. In the present paper, we call for researchers especially from countries and ecoregions that remain underrepresented in the majority of soil biodiversity assessments to join us. Together we will be able to provide science-based evidence to support soil biodiversity conservation and functioning of terrestrial ecosystems

Long term population dynamics - theory and reality in a peatland ecosystem

1. Population dynamics is a field rich in theory and poor in long‐term observational data. Finding sources of long‐term data is critical as ecosystems around the globe continue to change in ways that current theories and models have failed to predict. Here we show how long‐term ecological data can improve our understanding about palaeo‐population change in response to external environmental factors, antecedent conditions and community diversity. 2. We examined a radiometrically dated sediment core from the Didachara Mire in the mountains of south‐western Georgia (Caucasus) and analysed multiple biological proxies (pollen, fern spores, non‐pollen palynomorphs, charcoal, diatoms, chrysophyte cysts, midges, mites and testate amoebae). Numerical techniques, including multivariate ordination, rarefaction, independent splitting and trait analysis, were used to assess the major drivers of changes in community diversity and population stability. Integrated multi‐proxy analyses are very rare in the Caucasus, making this a unique record of long‐term ecological change in a global biodiversity hotspot. 3. Synthesis. Population changes in the terrestrial community coincided primarily with external environmental changes, while populations within the peatland community were affected by both internal and external drivers at different times. In general, our observations accord with theoretical predictions that population increases lead to greater stability and declines lead to instability. Random variation and interspecific competition explain population dynamics that diverged from predictions. Population change and diversity trends were positively correlated in all taxonomic groups, suggesting that population‐level instability is greater in more diverse communities, even though diverse communities are themselves more stable. There is a continuing need to confront population theory with long‐term data to test the predictive success of theoretical frameworks, thereby improving their ability to predict future change
