Peasant household survival strategies: rural transformation in the heartland of Turkey's hazelnut production belt
No full textThis study analyses the dynamics of persistence of the peasantry in a capitalist social formation through a case study of a village (Kayadibi) of hazelnut producers in the Central Black Sea region of Turkey. In the analysis the peasant household is given analytical priority as it is seen to be the single most important social institution through which the peasantry interacts, condition and is conditioned by the wider social, economic and political structures. Within such an analytical framework, this study concentrates on three areas of inquiry concerning the dynamics of survival of peasant modes. This is carried out in the context of the process of rural socio-economic transformation which took place under the impact of capitalism and with the start of hazelnut production for the world market in the early nineteenth century. These are: (1) the historical and contingent factors which contributed to the emergence and decline of big land- ownership and the new forms of development of capitalism in agriculture; (2) the areas of disputes and clashes of interests between the peasantry, the state and the merchants concerning the actual form of organization of the commodity and credit markets and further development or restriction of hazelnut production in the country; and (3) the patterns and mechanisms which enable the peasant households to have continuous access to land, labour and credit. The thesis arrives at the conclusion that the key to the persistence of the peasantry, as a property-owning social category of the society in a capitalist formation, is its strategy of diversifying its sources of income in order to decrease the degree of its dependency on land-bound agricultural production. This is combined with the strategy of consolidating its savings in the means of production in its own possession instead of using them to improve its standards of living and consumption
Comparative faunistic analysis of mite species on neglected and conventional pome fruit trees in Turkey
No full textInternational audienceThe paper presents the comparative faunistic analysis of leaf inhabiting mite species on neglected and conventionally grown pome fruit trees in Turkey as well as their diversity and distributions. For this purpose, twelve sampling areas were chosen in the Ordu region of Turkey. The study was carried out on four fruit tree species, apple (Malus domestica), pear (Pyrus communis), quince (Cydonia oblonga), and loquat (Eriobotrya japonica), between 2014 and 2019. In the study, a total of 42 mite species were identified from 12 families belonging to two orders. 92.43% of all species were found on the neglected trees, while 7.57% were reported in the conventional orchards. Among phytophagous mites, Cenopalpus pulcher on the neglected trees and Amphitetranychus viennensis in the conventional orchards showed the greatest overall constancy. The most abundant and common predatory species were Phytoseius finitimus on the neglected trees and Transeius wainsteini in the conventional orchards. A high faunistic similarity was found between the conventionally grown apple fruit trees and neglected apple, pear, quince, loquat trees. Considering together predatory and tetranychoid mites, the highest interspecific association index was revealed for the pair T. wainsteini-C. pulcher. Additionally, the pair Z. mali-T. wainsteini within the predatory mites and A. viennensis-C. pulcher within the tetranychoid mites had the highest index of association

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Analysis of Apsidal Motion and Light-Time Effect in Nine Eclipsing Binaries
No full textBu çalışmada dokuz tane örten çift yıldız sisteminin eksen dönmesi ve ışık-zaman etkisi, (O-C) analizi kullanılarak incelenmiştir. Analizlerden eksen dönmesi parametreleri ve çift sisteme bağlı muhtemel üçüncü cisme ilişkin parametreler belirlenmiştir. Dokuz sistem arasında en kısa eksen dönmesi dönemine sahip olan sistemin U Oph olduğu bulunmuştur (U= 19.7 ± 1.2 yıl). Bu çalışmada incelenen sistemler için, sistemlere çekimsel bağlı muhtemel üçüncü cisimlerin kütleleri, i= 90 derece varsayımı altında, 0.09 – 4.97 M? aralığında hesaplanmıştır. Eksen dönmesine sebep olan fiziksel süreçlerin, gözlenen eksen dönmesi hızına olan katkıları da hesaplanmıştır. Gözlenen eksen dönmesine en büyük katkının (RR Lyn ve V889 Aql dışında) bileşen yıldızların eksenleri etrafında dönmesi ve karşılıklı çekim nedeniyle oluşturdukları basıklık etkilerden geldiği görülmüştür. RR Lyn ve V889 Aql sistemlerinde ise eksen dönmesine genel göreliliğin katkısının daha büyük olduğu bulunmuştur. Diğer sistemlerde ise bu etkinin katkısının %1 ile %13 arasında olduğu hesaplanmıştır. Dokuz sistem için gözlenen eksen dönmesine üçüncü cisim nedeniyle oluşan etkinin diğer etkiler yanında ihmal edilebilir büyüklükte olduğu belirlenmiştir

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
