Power crafting at work: A phenomenological study on individual differences

What does having power mean, not for, but to an individual at work? In this paper, we focus on the individual’s concerns and experiences in the work setting and discuss how individuals conceptualise and construct their own power at work. This perspective is important due to its corresponding implications for how individuals choose their jobs, how they show proactive work behaviours, and how they are engaged in power relations in organisations. In-depth interviews with eleven participants were subjected to interpretative phenomenological analysis and key themes were identified to explain how these individuals cognitively, socially, and operationally crafted their ‘own’ versions of power in their organisations. Despite the idiosyncratic similarity among the participants, our analysis revealed a clear divide: ‘position-based power holders’ and ‘territory holders’. We first present our findings and results with interview excerpts and implications drawn from the emergent themes based on participant accounts. Next, we focus on two individual cases to explain how these individuals identified themselves as power holders within their own organisational contexts. Finally, we discuss our findings in association with other theoretical frameworks and concepts including the meaning of power, the organisational context, and proactive work behaviours

Phase Diagrams and Crossover in Spatially Anisotropic d=3 Ising, XY Magnetic and Percolation Systems: Exact Renormalization-Group Solutions of Hierarchical Models

Hierarchical lattices that constitute spatially anisotropic systems are introduced. These lattices provide exact solutions for hierarchical models and, simultaneously, approximate solutions for uniaxially or fully anisotropic d=3 physical models. The global phase diagrams, with d=2 and d=1 to d=3 crossovers, are obtained for Ising, XY magnetic models and percolation systems, including crossovers from algebraic order to true long-range order.Comment: 7 pages, 12 figures.

Quadruplet Selection Methods for Deep Embedding Learning

Recognition of objects with subtle differences has been used in many practical applications, such as car model recognition and maritime vessel identification. For discrimination of the objects in fine-grained detail, we focus on deep embedding learning by using a multi-task learning framework, in which the hierarchical labels (coarse and fine labels) of the samples are utilized both for classification and a quadruplet-based loss function. In order to improve the recognition strength of the learned features, we present a novel feature selection method specifically designed for four training samples of a quadruplet. By experiments, it is observed that the selection of very hard negative samples with relatively easy positive ones from the same coarse and fine classes significantly increases some performance metrics in a fine-grained dataset when compared to selecting the quadruplet samples randomly. The feature embedding learned by the proposed method achieves favorable performance against its state-of-the-art counterparts.Comment: 6 pages, 2 figures, accepted by IEEE ICIP 201

Perception-Distortion Trade-off in the SR Space Spanned by Flow Models

Flow-based generative super-resolution (SR) models learn to produce a diverse set of feasible SR solutions, called the SR space. Diversity of SR solutions increases with the temperature ($\tau$) of latent variables, which introduces random variations of texture among sample solutions, resulting in visual artifacts and low fidelity. In this paper, we present a simple but effective image ensembling/fusion approach to obtain a single SR image eliminating random artifacts and improving fidelity without significantly compromising perceptual quality. We achieve this by benefiting from a diverse set of feasible photo-realistic solutions in the SR space spanned by flow models. We propose different image ensembling and fusion strategies which offer multiple paths to move sample solutions in the SR space to more desired destinations in the perception-distortion plane in a controllable manner depending on the fidelity vs. perceptual quality requirements of the task at hand. Experimental results demonstrate that our image ensembling/fusion strategy achieves more promising perception-distortion trade-off compared to sample SR images produced by flow models and adversarially trained models in terms of both quantitative metrics and visual quality.Comment: 5 pages, 4 figures, accepted for publication in IEEE ICIP 2022 Conferenc

Saving Lives: The Principle of Distinction and the Realities of Modern War

WOS: 000332942700005PubMed ID: 24778561In this study, we assessed the feasibility of fetal RhD genotyping by analysis of cell-free fetal DNA(cffDNA) extracted from plasma samples of Rhesus (Rh) D-negative pregnant women by using real-time polymerase chain reaction (PCR). Fetal genotyping was performed on 30 RhD-negative women between 9 and 39 weeks of gestation who were referred to us for invasive testing [amniocentesis/chorionic villi sampling (CVS)]. The fetal RHD genotype was determined based on real-time PCR method. Exons 7 and 10 of the RHD and SRY genes were targeted. Among the pregnant women, 12 were carrying male and 17 were carrying female fetuses. Out of 29 pregnant women, 21 had RhD-positive and nine had RhD-negative fetuses. One sample) case 12, whose blood group was found to be AB Rh [+] (was excluded due to controversial results from repeated serological analyses. All prenatal results were in concordance with postnatal RhD status and fetal sex without false-positive or -negative results. Performing real-time PCR on cffDNA showed accurate, efficient and reliable results, allowing rapid and high throughput non invasive determination of fetal sex and RhD status in clinical samples

Characterizing the optical nature of the blazar S5 1803+784 during its 2020 flare

We report the results from our study of the blazar S5 1803+784 carried out using the quasi-simultaneous $B$, $V$, $R$, and $I$ observations from May 2020 to July 2021 on 122 nights. Our observing campaign detected the historically bright optical flare during MJD 59063.5$-$MJD 59120.5. We also found the source in its brightest ($R_{mag}$= 13.617) and faintest ($R_{mag}$= 15.888) states till date. On 13 nights, covering both flaring and non-flaring periods, we searched for the intraday variability using the power-enhanced $F-$test and the nested ANOVA test. We found significant variability in 2 out of these 13 nights. However, no such variability was detected during the flaring period. From the correlation analysis, we observed that the emission in all optical bands were strongly correlated with a time lag of $\sim$ 0 days. To get insights into its dominant emission mechanisms, we generated the optical spectral energy distributions of the source on 79 nights and estimated the spectral indices by fitting the simple power law. Spectral index varied from 1.392 to 1.911 and showed significant variations with time and $R-$band magnitude. We have detected a mild bluer-when-brighter trend (BWB) during the whole monitoring period while a much stronger BWB trend during the flare. We also carried out a periodicity search using four different methods and found no significant periodicity during our observation duration. Based on the analysis during the flaring state of the source one can say that the emissions most likely originate from the jet rather than the accretion disk.Comment: 17 pages, 8 figures, 7 tables, accepted for publication in The Astrophysical Journal (ApJ

Neotectonics of the South Marmara Sub-Region

Neotektonik dönemde Kuzey Anadolu Fayı ve kolları, inceleme alanı ve Marmara Bölgesi’nde en etkin tektonik yapıyı oluşturmaktadırlar. KAF, Marmara Bölgesi’nde kuzey ve güney olmak üzere iki kola ayrılır. Bunlardan Marmara Denizi’nin kuzeyinden geçen kol kuzey kol, güneyinden ve inceleme alanından geçen kol ise güney koldur. İnceleme alanında kuzeyde Edincik, Kapıdağı, Bandırma-Mudanya yükselimleri, güneyde Uludağ yükselimi ve Söğütalan platosu yer alır. Bu iki yükselim alanının ortasında doğu-batı uzanımlı bir çöküntü (depresyon) alanı gelişmiştir. Bu yükselim alanları ve çöküntü alanı, neotektonik dönemde Kuzey Anadolu Fayı’nın güney kolunun etkinliği ve kontrolü ile meydana gelmişlerdir. Çöküntü alanı içerisinde ise bir çok çek-ayır biçiminde havzalar oluşmuştur. Bölgede KAF’ın güney koluna ait faylar Yenice-Gönen, Manyas-Mustafakemalpaşa, Uluabat ve Bursa faylarıdır. Sismolojik veriler bölgedeki depremlerin  büyük ölçüde KAF’a ait güney kol üzerinde meydana geldiğini, hasar yapıcı ve yıkıcı depremlerin  hem doğrultu atımlı hem de eğim atımlı faylar üzerinde oluştuğunu göstermektedir.Anahtar Kelimeler: Güney Marmara Bölgesi, Kuzey Anadolu Fayı, çek-ayır havza, yanal atımlı fay.  In neotectonic period, North Anatolian Fault and its branches are the most active in the study area and Marmara Region. NAF is divided into two bracnhes as north and south  in the Marmara Region. The northern branch is located in the north of the Sea of Marmara. The southern branch is located in study area and south of the Sea of Marmara. The South Marmara Region has ptwo uplift areas located at southern and northern margins and a depression between these uplifts. The north uplifts are Edincik, Kapıdağı and Bandırma-Mudanya, south uplifts are Uludağ uplift and Söğütalan Plateau. The uplift and depression areas are contrelled by the southern branch of the NAF in the neotectonic period. In the depression area a lot of pull-apart style basins happened. The southern branch of the North Anatolian Fault, which consists of the Yenice-Gönen, Manyas-M.Kemalpaşa, Uluabat and Bursa faults. According to seismological data of  South Marmara Region, earthquakes have occured on the southern branch of the NAF and earthquakes show that the faults have not only strike-slip but also normal fault characteristics.Keywords: South Marmara Region, North Anatolian Fault, pull-apart basin, strike-slip faul
