A novel method for the determination of nickel in edible oils was proposed. The suggested procedure was on the basis of complexation of N, N'- bis(4-methoxysalicylidene) ethylenediamine and nickel in oily media and UVVisible spectrophotometric determination at 396 nm. The complex formation was completed within 20 seconds. The mixture of n-hexane and acetone (1:4, v/v) was used as solvent and the molar absorptivity of the complex was calculated as 6540 L mol-1 cm-1. The limits of detection and quantification were 0.24 and 0.82 µg g-1, respectively. The calibration graph was linear between 0.25-1.50 mg L-1 nickel concentration with 0.9995 correlation coefficient. The reliability of the suggested method was tested by analysis of organometallic nickel standard and the recovery and relative standard deviation were found as 97.0 % and 3.8 %, respectively. Furthermore, the developed method was successfully applied on nickel spiked real samples and recovery values were between 90.0 - 104.0 %. ; Bu çalışmada, yenilebilir yağlarda nikel tayini için yeni bir metot sunulmuştur. Önerilen prosedür, N, N'-bis(4-metoksisalisiliden) etilendiamin ve nikelin yağ ortamında kompleksleşmesi ve 396 nm'de UV-görünür bölgede spektrofotometrik tayinine dayanmaktadır. Kompleks oluşumu 20 saniyede tamamlanmaktadır. n-Hekzan ve aseton karışımı (1:4, h/h) çözücü olarak kullanılmış ve kompleksin molar absorpsiyon katsayısı 6540 L mol-1 cm-1 olarak hesaplanmıştır. Tayin ve gözlenebilme sınırları sırasıyla 0,24 ve 0,82 µg g-1 olarak bulunmuştır. Kalibrasyon grafiği 0,25-1,50 mg L-1 nikel derişimi aralığında doğrusaldır ve korelasyon katsayısı 0,9995'dir. Önerilen yöntemin gerçekliği organometalik nikel standardı kullanılarak test edilmiş; % geri kazanım ve % bağıl standart sapma değerleri sırasıyla % 97,0 ve % 3,8 olarak bulunmuştur. Ayrıca, geliştirilen yöntem nikel katılmış gerçek örneklerde de başarıyla uygulanmış ve % geri kazanım değerleri ,0 -104,0 aralığında bulunmuştur.

Background: It has been said that organisational democracy influences the improvement of behavioural orientations related to being good organisational citizens.Objectives: The main purpose of this study was to provide empirical evidence on bank employees' perceptions towards organisational democracy and their organisational citizenship behaviour, in addition to indicating whether a relationship exists between organisational democracy and organisational citizenship behaviour.Method: Data were collected through the use of a questionnaire. The population of the study consisted of bank employees working at branches of a private bank located in the province of Istanbul, Turkey. A total of 240 bank employees took part in the study. Data analysis entailed the computation of descriptive statistics, as well as t-test, analysis of variance (ANOVA) test, correlation analysis and regression analysis.Results: The study results indicated that a statistically significant relationship exists between the bank employees' perceptions of organisational democracy and their organisational citizenship behaviour.Conclusion: Through this study, it can be concluded that organisational democracy is an important variable that can be used by managers to facilitate the favourable behaviour of employees and to promote the sense of citizenship that employees feel towards their organisation, which in turn will positively influence organisational performance.

The primary objective of the present study is to identify the antecedents of voter loyalty, with a particular focus on the mediating role of party attachment in the relationship between inner‐self, social‐self, trust, and loyalty. Using a convenience sampling method, the data for this study were gathered from a sample of 750 voters residing in a developing European country, Turkey. The collected data were analyzed using confirmatory factor analyses and structural equation modeling. The results of the study demonstrate that significant and positive relationships exist between the aforementioned antecedents (i.e., inner‐self, social‐self, trust, and party attachment) and voter loyalty. Additionally, the findings suggest that party attachment acts as a mediator between the antecedents and loyalty. Drawing on these results and the existing literature on voter behavior and practice, the authors discuss methodological, theoretical, and practical implications for inner‐self, social‐self, trust, and party attachment.

In this paper, we illustrate a new, simple and complementary ground-based methodology to retrieve the vertically resolved atmospheric precipitation intensity through a synergy between measurements from the National Aeronautics and Space Administration (NASA) Micropulse Lidar network (MPLNET), an analytical model solution and ground-based disdrometer measurements. The presented results are obtained at two mid-latitude MPLNET permanent observational sites, located respectively at NASA Goddard Space Flight Center, USA, and at the Universitat Politècnica de Catalunya, Barcelona, Spain. The methodology is suitable to be applied to existing and/or future lidar/ceilometer networks with the main objective of either providing near real-time (3 h latency) rainfall intensity measurements and/or to validate satellite missions, especially for critical light precipitation (<3 mm h-1). ; The MPL measurements and processing in Barcelona are supported by the European Union (H2020, grant 654109, ACTRIS-2), the European Fund for Regional Development, the Spanish Government (grants TEC2015-63832-P, CGL2015-65627-C3-2-R, CGL2016-81828-REDT and CGL2017-90884-REDT) and the Catalan Government (grant 2014 SGR 583).

Klappentext: Though persistently overshadowed by the Great War in historical memory, the two Balkan conflicts of 1912-1913 were among the most consequential of the early twentieth century. By pitting the states of Greece, Bulgaria, Serbia, and Montenegro against a diminished Ottoman Empire - and subsequently against one another - they anticipated many of the horrors of twentieth-century warfare even as they produced the tense regional politics that helped spark World War I. Bringing together an international group of scholars, this volume applies the social and cultural insights of the 'new military history' to revisit this critical episode with a central focus on the experiences of both combatants and civilians during wartime.
