Exploring publicness as social practice: An analysis on social support within an emerging economy

AbstractBy utilizing the concepts of field, habitus, and capital inherited from Bourdieu, this study explores publicness as a social practice. In doing this, the paper problematizes publicness concerning accountability and public value and empirically explores the organization of social support delivery in Istanbul. We posit our research question: In what manners does publicness open up a space for collaboration and convergence in relation to accountability? The data gathering and analysis follow a qualitative methodology. We found different forms of publicness under three different conditionalities: (1) publicness as political authority based on hierarchization and centralization; (2) publicness as competing positions produced by diverse actors and their diverse positions taken beyond hierarchical relations; (3) publicness as social inclusion and diversity that is all‐embracing by employing more inclusive practices. Publicness relationally unfolds public value with and among formal rules, voluntary practices, and networks. By delving into constitutive elements of practice—symbolic capital and habitus—engaging in the field struggles of redefining and owning publicness, the paper goes beyond the conventional dichotomy of normative versus empirical conceptualizations of publicness and instead differentiates among distinct forms of publicness in different conditionalities and contributes to the literature by bridging publicness and accountability habitus.</jats:p

Effects Of Wind Datas Collected At Different Heights And Time Intervals To The Wind Potential

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Enerji Enstitüsü, 2009Thesis (M.Sc.) -- İstanbul Technical University, Energy Institute, 2009Enerji fiziksel olarak bir sistemin iş yapabilme kabiliyeti olarak tanımlansa da, günümüzde ülkelerin politikalarında yer alması sebebiyle bu anlamının çok ötesinde bir yer edinmiştir. Fosil yakıtların yakın bir gelecekte tükenecek olması dolayısıyla, enerji yönü olan politikalar tarih boyunca hiç bu kadar ön planda olmamıştı. Bu politikalar rüzgar ve güneş enerjisi gibi, fosil yakıtlara alternatif olarak kullanılabilecek sistemlerin geliştirilmesine sebep olmuştur. Özellikle son 10 yılda rüzgar enerjisi ülkemizde ve tüm dünyada önde gelen sektörlerden olmuştur. Rüzgar enerjisine olan bu eğilim akademik alanda da kendini göstermiş ve bir çok çalışma ile belli bir bölge için maksimum enerji kazancı sağlanmasına yönelik öneriler getirilmiştir. Bu sebeple bu çalışmanın amacı Balıkesir'deki yüksek enerji yoğunluklu bir bölgede yapılan rüzgar ölçümleri kullanılarak, güç kanununun farklı alfa değerleri ile kullanılmasıyla sonuçlardaki değişiklikleri ortaya koymaktır. Ayrıca türbin göbek yüksekliğinde yapılan ölçümlerin önemini vurgulamak da yine bu çalışmanın amaçlarındandır. Bu çalışmalar hem 3 farklı türbin modeli için 36 MW'lık bir rüzgar elektrik santrali tasarlanarak, hem de ölçüm noktasında tek türbin olduğu varsayılarak, yaklaşık 100'e yakın farklı durum için yapılmıştır. Sonuç olarak ölçümlerin türbin göbek yüksekliğinde yapılmasının gerekli olduğu görülmüş, empirik bağıntıların enerji analizlerinde ciddi hatalara sebep olabileceği anlaşılmıştır.Although energy is defined as the ability of a sisytem to perform ?work?, today, it means more than its physical meaning due to its importance on countries policies. Policies with energy aspect, has never been such considerable since energy has been used for centuries as a result of fossil fuels is getting run out and will be completely exhausted in near future. However there always have been alternative energy to the fossil sources, like solar and wind energy. Especially with last decade wind energy has become more populer and a leading sector all over the world including Turkey. This trend has resulted with lots of academic studies to improve the energy acquisition from wind at site specific conditions. Therefore scope of this study is to determine the wind energy potential at Balikesir / Turkey by using different alpha values with ?Wind Power Law?. It also aimed with this study that to identify the importance of the wind measurements at turbine hubheights. All these studies have been performed with 3 different wind turbine models for 36 MW installed power capacity and with one turbine at measurement point, that means energy yield calculations for almost 100 different conditions. Consequently all results showed that the wind speed measurements should be made at hubheights of turbines. Otherwise empiric relations will cause errors on calculations.Yüksek LisansM.Sc

Chemical composition and comparative antibacterial properties of basil essential oil against clinical and standard strains of campylobacter spp.

This study has aimed to evaluate comparative antibacterial activity of basil essential oil against clinical and standard isolates of Campylobacter spp. by different methods as agar well diffusion, agar and broth dilution methods. Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GC/MS) analysis were also examined to determine the chemical composition of the tested essential oil. GC/ MS analysis showed that, basil essential oil was predominated by methyl chavicol (86.6%) followed by 1,8-cineole (2.8%) and ?-bergamotene (2.4%). Although, inhibition zone diameters were in the range of 10.9±0.8 to 21.8±1.4 mm, higher MIC values were obtained against clinical strains compared with standard ones. Due to the differences in antimicrobial resistance of the clinical and standard strains, antimicrobial activity tests should be carried out with isolates from different sources. © 2019, İstanbul Medipol University.

Exploring the role of reanalysis data in simulating regional wind generation variability over Northern Ireland

As wind generation increases, system impact studies rely on predictions of future generation and effective representation of wind variability. A well-established approach to investigate the impact of wind variability is to simulate generation using observations from 10 m meteorological mast-data. However, there are problems with relying purely on historical wind-speed records or generation histories: mast-data is often incomplete, not sited at a relevant wind generation sites, and recorded at the wrong altitude above ground (usually 10 m), each of which may distort the generation profile. A possible complimentary approach is to use reanalysis data, where data assimilation techniques are combined with state-of-the-art weather forecast models to produce complete gridded wind time-series over an area. Previous investigations of reanalysis datasets have placed an emphasis on comparing reanalysis to meteorological site records whereas this paper compares wind generation simulated using reanalysis data directly against historic wind generation records. Importantly, this comparison is conducted using raw reanalysis data (typical resolution ∼50 km), without relying on a computationally expensive “dynamical downscaling” for a particular target region. Although the raw reanalysis data cannot, by nature of its construction, represent the site-specific effects of sub-gridscale topography, it is nevertheless shown to be comparable to or better than the mast-based simulation in the region considered and it is therefore argued that raw reanalysis data may offer a number of significant advantages as a data source
