Paleoglaciations in Anatolia: A Schematic Review and First Results

Anatolia is situated in the Eastern Mediterranean region between 36 – 42N and 26 – 45E. The geological records of paleoglaciations in the high terrains of Anatolia are key archives to quantify paleoclimate change in the Eastern Mediterranean area. The climate of the Eastern Mediterranean region is influenced by three main atmospheric systems: the main middle to high latitude westerlies, the mid-latitude subtropical high-pressure systems, and the monsoon climate. Glacial geological studies in Turkey have started in the late 19th century. Glacial deposits are found mainly in the eastern, northeastern and southern part of the Anatolian Peninsula. Anatolia is the fundamental element to understand the interactions between paleoenvironment, climatic variations, and development of the human societies. As the Taurus and Black Sea Mountains are sensitively situated for the paleoclimatic reconstructions, a chronostratigraphic framework on the paleoglaciation should be elaborated. The timing of the Last Glacial Maximum (LGM) in Anatolia is still unknown. Our first results from Kavron Valley (Kaçkar Mountains, NE Turkey) are encouraging for the reconstruction of paleoglaciations in Turkey and related paleoclimatological interpretations although it is presently difficult to pinpoint the classical Last Glacial Maximum – Younger Dryas – Little Ice Age moraine sequences in the field.

Noble gas, CFC and other geochemical evidence for the age and origin of the Bath thermal waters, UK

The city of Bath is a World Heritage site and its thermal waters, the Roman Baths and new spa development rely on undisturbed flow of the springs (45 °C). The current investigations provide an improved understanding of the residence times and flow regime as basis for the source protection. Trace gas indicators including the noble gases (helium, neon, argon, krypton and xenon) and chlorofluorocarbons (CFCs), together with a more comprehensive examination of chemical and stable isotope tracers are used to characterise the sources of the thermal water and any modern components. It is shown conclusively by the use of 39Ar that the bulk of the thermal water has been in circulation within the Carboniferous Limestone for at least 1000 years. Other stable isotope and noble gas measurements confirm previous findings and strongly suggest recharge within the Holocene time period (i.e. the last 12 kyr). Measurements of dissolved 85Kr and chlorofluorocarbons constrain previous indications from tritium that a small proportion (<5%) of the thermal water originates from modern leakage into the spring pipe passing through Mesozoic valley fill underlying Bath. This introduces small amounts of O2 into the system, resulting in the Fe precipitation seen in the King’s Spring. Silica geothermometry indicates that the water is likely to have reached a maximum temperature of between 69–99 °C, indicating a most probable maximum circulation depth of ∼3 km, which is in line with recent geological models. The rise to the surface of the water is sufficiently indirect that a temperature loss of >20 °C is incurred. There is overwhelming evidence that the water has evolved within the Carboniferous Limestone formation, although the chemistry alone cannot pinpoint the geometry of the recharge area or circulation route. For a likely residence time of 1–12 kyr, volumetric calculations imply a large storage volume and circulation pathway if typical porosities of the limestone at depth are used, indicating that much of the Bath-Bristol basin must be involved in the water storage.

Gender differences at the transition to higher education between migrants and non-migrants: A comparison between Switzerland and France

Within Western societies women or girls meanwhile outperform men or boys with regard to attainments in primary and secondary education. For example concerning upper secondary degrees the share of females attaining the Matura approaches two thirds in Switzerland, while the share of females attaining the Baccalaureate exceeds fifty per cent in France. However, if transitions to higher education are regarded, the share of entitled females entering such institutions is significantly lower than among men in Switzerland. An opposite pattern is observed in France where females outperform men at this educational stage, too. With regard to migrant background, it has been shown by previous research focussing on secondary effects of ethnic origin that such youths enter the more demanding educational tracks (e.g. higher education) more often than their non-migrant peers if controlled for eligibility, their lower socioeconomic status and performances. However, so far only a few studies refer to the question of a possible gender gap regarding secondary effects of ethnic origin (e.g. Fleischmann et al., mimeo). Thus, with regard to a possible interaction of a migrant background and - for example - a female gender, it is important to note that in both countries many migrant groups have their origins in countries and regions where male advantage remains very strong. This is in particular the case for migrant groups from non-Western countries, e.g. Turkey, Algeria, Marocco or Tunisie, where gender gaps in the literacy rates of up to 18 per cent are still observed. In order to investigate the question of a possible disadvantages of women with a migrant background stemming from such countries when compared to non-migrant females two panel studies - the Tree data in Switzerland and the Panel d’élèves 1995 in France -, are analysed.

Approaching diplomatic and courtly gift-giving in Europe and Mughal India. Shared practices and cultural diversity

This article deals with courtly gift-giving practices in Europe and Mughal India from a comparative and interwoven perspective. Given the historiographical lacunae on Mughal gift-giving, the article presents preliminary observations for further research. Unlike most contributions to this volume, this article understands the notion of diversity in terms of an intercultural diversity that came to the fore in courtly contexts and in diplomatic encounters. My arguments are bifold. On the one hand, European and Mughal rulers and their envoys shared a common ground of diplomatic gift-giving practices that were shaped by an understanding of what was worthy of giving and of the symbolic power of the given objects. On the other hand, courtly gift-giving practices were embedded in different social and cultural environments in Europe and India. By looking at the notion of the ‘gift’ and the social organisation of the Mughal elite, it becomes clear that pīshkash was an idiosyncratic concept in South and Central Asian contexts and that offerings of manṣabdārs to the Mughal emperor had a different character than those of European courtiers to their rulers.

Dynamics of the last four glacial terminations recorded in Lake Van, Turkey

A well-dated suite of Lake Van climate-proxy data covering the last 360 ka documents environmental changes over 4 glacial/interglacial cycles in Eastern Anatolia, Turkey. The picture of cold and dry glacials and warm and wet interglacials emerging from pollen, organic carbon, authigenic carbonate content, elemental profiling by XRF and lithological analyses is inconsistent with classical interpretation of ox- ygen isotopic composition of carbonates pointing to a more complex pattern in Lake Van region. Detailed analysis of glacial terminations allows for the constraining of a depositional model explaining different patterns observed in all the proxies. We hypothesize that variations in relative contribution of rainfall, snowmelt and glacier meltwater recharging the basin have a very important role for all sedimentary processes in Lake Van. Lake level of glacial Lake Van, predominantly fed by snowmelt, was low, the water column was oxic, and carbonates precipitating in the epilimnion recorded the light isotopic signature of inflow. During terminations, increasing rainfall and significant supply of mountain glaciers' meltwater contributed to lake level rise. Increased rainfall enhanced density gradients in the water column, and hindered mixing leading to development of bottom-water anoxia. Carbonates precipitating during terminations show large fluctuations in their isotopic composition. Full interglacial conditions in Lake Van are characterized by high or slowly falling lake level. Rainfall and snowmelt feed the lake but due to re-established mixing, the isotopic composition of authigenic carbonates is heavier and closer to that of evaporation-influenced lake water than that of runoff representing snowmelt and atmospheric precipitation.

A Preliminary Impact Assessment of Doha Round Results on Agricultural Policies in Turkey

Turkish agriculture has been experiencing a period of unique policy experiment over the last couple years. A World Bank-initiated project, called the Agricultural Reform Implementation Project (ARIP), has been at the forefront of policy change. It was initially promoted by the Bank as an exemplary reform package which could also be adopted by other developing countries. It was introduced in 2001 as part of a major International Monetary Fund (IMF)/World Bank-imposed program of “structural adjustment” after the country had been hit by a major financial crisis. The project has finally come to an end in 2009, and there is now an urgent need for a retrospective assessment of its overall impact on the agricultural sector. Has it fulfilled its ambitious objective of reforming and restructuring Turkish agriculture? Or should it be recorded as a failure of the neo-liberal doctrine? This book aims at finding answers to these questions by investigating the legacy of ARIP from a multi-disciplinary perspective.

Immunization against gonadotropin-releasing hormone in dairy cattle: Antibody titers, ovarian function, hormonal levels, and reversibility

Suppression of cyclic activity in cattle is often desired in alpine farming and for feedlot cattle not intended for breeding. A cattle-specific anti-GnRH vaccination (Bopriva, Zoetis Australia Ltd., West Ryde, Australia) is approved for use in heifers and bulls in New Zealand, Australia, Mexico, Brazil, Argentina, Turkey, and Peru. Eleven healthy, cyclic Swiss Fleckvieh cows were included in the study and vaccinated twice with Bopriva 4wk apart. Injection site, rectal body temperature, and heart and respiratory rates were recorded before and 3d following each vaccination. Blood samples were taken weekly for progesterone and estrogen analysis and to determine GnRH antibody titer. Ovaries were examined weekly, using ultrasound to count the number of follicles and identify the presence of a corpus luteum. Thirty weeks after the first vaccination, the cows were subjected to a controlled internal drug-releasing device-based Select-Synch treatment. The GnRH antibody titers increased after the second vaccination and peaked 2wk later. Estrogen levels were not influenced by vaccination, and progesterone level decreased in 7 of 11 cows up to 3wk after the second vaccination and remained low for 10 to 15wk following the second vaccination. The number of class I follicles (diameter ≤5mm) was not influenced by vaccination, whereas the number of class II follicles (diameter 6-9mm) decreased between 7 and 16wk after the first vaccination. Class III follicles (diameter >9mm) were totally absent during this period in most cows. The median period until recurrence of class III follicles was 78d from the day of the second vaccination (95% confidence interval: 60-92d). After vaccination, all cows showed swelling and pain at the injection site, and these reactions subsided within 2wk. Body temperature and heart and respiratory rates increased after the first and second vaccinations and returned to normal values within 2d of each vaccination. The cows in our study were not observed to display estrus behavior until 30wk after the first vaccination. Therefore, a Select-Synch protocol was initiated at that time. Ten cows became pregnant after the first insemination (the remaining cow was reinseminated once until confirmed pregnancy). Bopriva induced a reliable and reversible suppression of reproductive cyclicity for more than 2mo. The best practical predictor for the length of the anestrus period was the absence of class III follicles.

Dental knowledge and attitude toward school dental-health programs among parents of kindergarten children in Winterthur.

The current study investigated the attitudes and knowledge regarding diet and oral hygiene of parents with kindergarten children. The parents' statements were evaluated in terms of their socioeconomic background and were compared with the annual clinical examination of the children. The objective of the study was to assess the effectiveness of the school dental-health program and adapt it to today's societal needs. Of those who participated in the interview, 61% were Swiss, 16% were from former Yugoslavia or Turkey, and 12% each from the EU or other countries. Of the children examined, 39% already had caries, and 18% of those showed more than two lesions. The parents' knowledge correlated with the severity of the child's caries as well as with the parents' income, country of origin, and education. There was a correlation between the child's dental decay and lower income, as well as lower education and non-Swiss nationality of the parents. Parents with higher income and better education more often participated in the preschool's preventive program. Parents from former Yugoslavia or Turkey participated less frequently than parents from other countries. The study demonstrated that parents who especially needed instruction and prophylaxis are contacted too late or not at all through the dental-health program at kindergarten and that new approaches to prevention should be implemented to more effectively reach the parents.
