A TEST FOR ASYMMETRIC CENTRAL BANK PREFERENCES IN TURKEY

The time inconsistency based KPBG models that tried o explain the inflation bias lost their popularity as inconsistent Central Bank behaviors changed in time. However, high inflation for countries like Turkey i s still a problem and a new theory to explain this ‘time consistent’ inflation bias is in need. A theory based on non-linear or asymmetric Central Bank behavior is d eveloped during the last decade to fill this gap. One way to test the empiri cal validity of the theorem is based on a Taylor Rule variant asymmetric model. Th is model is tested here for Turkey as it is one of the inflation targeting coun tries roughly for the last ten years.
Why do we need 5-DOF force feedback? The case of violin bowing

The analysis of gestures associated with playing musical instruments can provide insight into the haptic cues used to exercise control over acoustic parameters. In this study, forces acting on the bow as experienced by the violinist are described based on an analysis of bowing gesture motion capture data in crescendo-decrescendo notes, finally leading to a formulation of criteria for haptic virtual bow controllers.

Reflection and Risk: An Experiment on Managerial Traits and Organizational Structure∗

We study how micro-level characteristics of managers, specifically cognitive ability and risk preferences, affect the structure and function of organizations. To do so, we model a managerial decision environment in which a manager both determines the skill heterogeneity of her workers and determines whether to retain or delegate the ability to allocate tasks. The manager prefers delegating when uncertainty is sufficiently high relative to the incentive conflict with her workers, which is endogenously determined by her chosen team composition. Experimental data supports the direction of the main predictions, though it shows how and why participants deviate from expected behavior. In particular, we find that higher cognitive ability leads to better team selection, while greater risk tolerance allows managers to optimally delegate decision rights. Generally, the results highlight the difficulties in navigating complex managerial environments and illustrate potentially costly ways in which managers seek to simplify their decisions.
Why is capital slow moving? Liquidity hysteresis and the dynamics of limited arbitrage∗

Will arbitrage capital flow into a market experiencing a liquidity shock, mitigating the adverse effect of the shock on price efficiency? Using a stochastic dynamic equilibrium model with privately informed capital-constrained arbitrageurs, we show that arbitrage capital may actually flow out of the illiquid market. When some capital flows out, the remaining capital in the market becomes trapped because it becomes too illiquid for arbitrageurs to want to close out their positions. This mechanism creates endogenous liquidity regimes under which temporary shocks can trigger flight-to-liquidity resulting in “liquidity hysteresis” which is a persistent shift in market liquidity and price informativeness.
Neuraxial analgesia in cardiac surgery: a review of risks

Principal neuraxial techniques in cardiac anesthesia are thoracic epidural analgesia (TEA), spinal analgesia, and paravertebral blocks. Although all techniques present possible advantages in outcome after cardiac surgery, each technique poses specific risks. Major risks of TEA and spinal analgesia are epidural or spinal hematomas. This risk can be quantified at ca. 1:2100 and 1:2900 with a confidence interval of 95%. This risk does not seem to be significantly different from the nonobstetrical population; however, an exact calculation is hampered by cases that are not published and no exact information about how many patients undergo cardiac surgery with TEA or spinal analgesia worldwide per year. The most severe problem with paravertebral blocks is inadvertent pneumothorax, which can be quantified as between 0.4% and 3%. The risk of epidural or spinal abscess with TEA or spinal analgesia is minimal provided that usual antiseptic measures are in place. Minor discomfort caused by TEA is paresthesia of the upper limbs because of the dermatomes necessary to block the pain at the surgical site. Hypotension can occur both with TEA and spinal analgesia, especially when the technique of “high spinal analgesia” is used; fluid replacement and sensible dosing techniques help to limit or avoid this. Several adjuncts, mainly opioids, can be added to all neuraxial techniques, and side effects, such as sedation, PONV, or bowel motility impairment, have to be considered. In general, these neuraxial techniques present a risk profile which, with the available data, is similar to their use in other major surgery, such as vascular, thoracic, or abdominal surgery.

A cross-sh elf gradient in δ15N stab le isotope values of kr ill and pollock indicates seabird foraging patter ns in the Bering Sea

Concurrent measurements of predator and prey δN isotope values demonstrated that a cross-shelf isotopic gradient can propagate through a marine food web from forage species to top-tier predators and indicate foraging areas at a scale of tens of kilometers. We measured δC and δN in muscle tissues of thick-billed murres (Uria lomvia) and black-legged kittiwakes (Rissa tridactyla), and in whole body tissues of walleye pollock (Gadus chalcogrammus) and krill (Thysanoessa spp), sampled across the continental shelf break in the Bering Sea in 2008 and in 2009. We found significant basin-shelf differences at fine scales (o100 km) in δN among murres but not kittiwakes, and no such differences in δC in either seabird species at that scale. We then quantified the multi-trophic signal and spatial structure of a basinshelf δNitrogen gradient in the central and southern Bering Sea, and used it to contrast foraging patterns of thick-billed murres and kittiwakes on the open ocean. Seabird muscle δN values were compared to baselines created from measurements in krill and pollock tissues sampled concurrently throughout the study area. Krill, pollock, and murre tissues from northern, shallow, shelf habitat (o200 m) were enriched 1–2‰ in δN relative to samples taken from deeper habitats (4200 m) to the south and west. Krill δN baseline values predicted 35–42% of the variability in murre tissue values. Patterns between kittiwakes and prey were less coherent. The persistence of strong spatial autocorrelation among sample values, and a congruence of geospatial patterns in δN among murre and prey tissues, suggest that murres forage repeatedly in specific areas. Murre isotope values showed distinct geospatial stratification, coincident with the spatial distribution of three colonies: St. Paul, St. George, and Bogoslof. This suggests some degree of foraging habitat partitioning among colonies. & 2014 Elsevier Ltd. All rights reserved.
Dimensioning Cellular WiMAX Part I : Singlehop Networks

Providing diverse broadband services economically to everyone is a major challenge for the telecommunication community. WiMAX or IEEE 802.16 is one of the most promising radio access technology to offer performances similar to wired xDSL systems, which surpass current 3G mobile data rates. Different deployment concepts are foreseen for WiMAX networks. They can cover isolated areas such as rural hot spots, private campus networks, and remote neighborhoods. Even more promising is WiMAX deployed as a cellular network that offers ubiquitous broadband services over large geographic regions to mobile subscribers. This paper discusses an analytical approach to dimension cellular OFDM-based WiMAX networks. Achievable UL and DL Carrier to Interference and Noise Ratios (CINRs) are calculated. A worst case analysis results in valuable indications for dimensioning cellular WiMAX networks within various singlehop scenarios.
p300/CBP inhibitor A-485 alleviates acute liver injury by regulating macrophage activation and polarization

High morbidity and mortality are associated with acute liver injury (ALI) for which no effective targeted drugs or pharmacotherapies are available. Discovery of potential therapeutic targets as well as inhibitors that can alleviate ALI is imperative. As excessive inflammatory cytokines released by macrophages are a critical cause of liver injury, we aimed to find novel compounds that could inhibit macrophage expression of inflammatory cytokines and alleviate liver injury. Methods: A high throughput assay was established to screen a small molecule inhibitor library of epigenetic targets. A highly selective catalytic p300/CBP inhibitor A-485 was identified as a potent hit in vitro and administrated to the lipopolysaccharide (LPS)/D-galactosamine (GalN)-induced mice in vivo. For in vitro analysis, RAW264.7 cells and primary BMDM cells exposed to LPS were co-incubated with A-485. A model of acute liver injury induced by LPS and GalN was used for evaluation of in vivo treatment efficacy. Results: A-485 inhibited LPS-induced inflammatory cytokine expression in a concentration-dependent manner in vitro. Significantly, A-485 administration alleviated histopathological abnormalities, lowered plasma aminotransferases, and improved the survival rate in the LPS/GalN-stimulated mice. Integrative ChIP-Seq and transcriptome analysis in the ALI animal model and macrophages revealed that A-485 preferentially blocked transcriptional activation of a broad set of pathologic genes enriched in inflammation-related signaling networks. Significant inhibition of H3K27ac/H3K18ac at promoter regions of these pivotal inflammatory genes was observed, in line with their suppressed transcription after A-485 treatment. Reduced expression of these pathological pro-inflammatory genes resulted in a decrease in inflammatory pathway activation, M1 polarization as well as reduced leukocyte infiltration in ALI mouse model, which accounted for the protective effects of A-485 on liver injury. Conclusion: Using a novel strategy targeting macrophage inflammatory activation and cytokine expression, we established a high-throughput screening assay to discover potential candidates for ALI treatment. We demonstrated that A-485, which targeted pathological inflammatory signaling networks at the level of chromatin, was pharmacologically effective in vivo and in vitro. Our study thus provided a novel target as well as a potential drug candidate for the treatment of liver injury and possibly for other acute inflammatory diseases.
Teachers ’ Pedagogical Content Knowledge for Teaching “ The Nature of Organism ”

Effective and experienced teachers have the capacity to transform and enact subject matter into forms that can be understood by students. The capacity to transform depends on the blending of content and pedagogy and it is conceptualised as pedagogical content knowledge (PCK). The purpose of this study is to investigate the understandings and practices that comprise a biology teacher’s PCK. In this research, the research participant demonstrated her PCK through writing a content representation (CoRe), teaching in the classroom, and discussion during the interview. The researcher determined the extent and nature of her PCK in relation to the Magnusson et al (1999). The findings expose the teacher’s understanding and practice of PCK supported teaching and learning science based on constructivism. The teacher had strong, clearly articulated views on the NOS which she implemented all components of PCK confidently into her teaching.

Online Reprogrammable Multi Tenant Switches

Recent research shows many benefits for cloud workloads and network operations when putting software functionality onto switches. Sharing the physical resources of a programmable switch between multiple tenants and workloads enables the widespread deployment of on-switch software functionality. Currently, changing the program on a programmable switch incurs significant switch downtime, connectivity loss, and service interruption. We, therefore propose a modification to the common programmable switch architecture to enable hot-pluggability, the ability to insert, modify, and remove on-path software functionality without interrupting the network operation. With hot-pluggability, a programmable switch can be shared between applications of different on-switch lifetime and therefore also between different tenants. Such sharing requires performance and program isolation between different on-switch functions and tenants. Our proposal makes on-switch software functionality deployable within production networks and enables programmable switches to be offered as a service to multiple tenants within cloud and ISP networks.

DEVELOPMENT OF AN IMPROVED DYNAMIC MODEL OF A GRID-TIED MICRO-HYDRO POWER PLANT Molina

Conventional small-scale hydropower plants are run-of-the-river (ROR) stations that use a fixed speed drive with mechanical regulation of the turbine water flow rate in order to control the power harvested from the water. This design enables to reach high efficiency over a wide range of water flow rates but using a complex operating mechanism. This conventional arrangement is in consequence expensive and tends to be more affordable for large-scale grid-connected systems. In this paper, an enhanced configuration of a micro-hydro power plant (MHPP) is proposed, which is based on a smaller, lighter, more robust and more efficient higher-speed turbine. The suggested design is fairly simple and eliminates all the mechanical adjustments through a novel efficient electronic power conditioning system (PCS) for connecting to the power utility grid. The innovative topology employed consists of a three-level cascaded Z-source inverter that allows the flexible, efficient and reliable generation of high quality electric power from the MHPP at lower costs. Moreover, a full detailed model of the MHPP is derived and a three-level control scheme is designed. The dynamic performance of the designed architecture is verified by computer simulations.
Thermo-chemical and antioxidant properties of cryogenically ground turmeric powder

In present communication, thermal, chemical and antioxidant properties of turmeric powder, for cryogenically grinding conditions at different moisture contents (4%, 7%, 10%, & 13% w.b.) were investigated. Specific heat, thermal conductivity, thermal diffusivity, glass transition temperature, curcumin content, colour parameters, volatile oil, oleoresin content, total phenols and antioxidant activity in DPPH assay, of cryogenically ground turmeric powder were evaluated. Specific heat increased from 10.45 to 16.26 kJ kg-1K-1 and 10.36 to 14.22 kJ kg-1K-1 in the temperature range of -100°C to +100°C in cryoground and control samples of turmeric powder, respectively. The values of thermal conductivity and thermal diffusivity of control and cryo-ground turmeric powder increased from 0.051 to 0.077 W m-1K-1, 0.049 to 0.059 W m-1K-1 and 0.93×10-8 to 1.20 ×10-8 m2s-1, 1.02×10-8 to 1.08 ×10-8 m2s-1, respectively. Cryo-ground turmeric powder retained oleoresin, curcumin, phenol content and antioxidant activity, 87-90%, 76-79%, 93-95%, 84-85%, respectively.
SOME EFFECTS OF PARTICLE SHAPE ON THE MECHANICAL BEHAVIOUR OF GRANULAR MATERIALS

The behaviour of a granular material depends on the shape, material properties and packing of the grains. Starting with a particle characterization, the ability to make predictions of the macroscopic behaviour of an assembly of particles without recourse to laboratory or numerical experiments would be very useful. With this ultimate goal in mind, this work presents some first findings of an investigation into the effects on macroscopic behaviour of two key measures of particle shape: form and angularity. The form of a particle is quantified using the Longest (L), Intermediate (I) and Shortest (S) dimensions of an equivalent scalene ellipsoid; A sum of the local volumetric deviations of the particle from that ellipsoid as a ratio of the ellipsoid volume is used as a measure of angularity. Discrete element, periodic cell simulations of ellipsoidal and realistic particle shapes sampled from railway ballast are used to investigate mechanical behaviour in terms of critical state friction angle. Characterization of the observed behaviour in terms of a single shape parameter is explored. It is found that deviation of particle form from that of a sphere together with increases in angularity both lead to higher angles of friction at critical state. It is argued that, at least to some extent, the higher critical state strength exhibited by non-spherical particles is due to their form and/or angularity suppressing particle rotation and leading to increased interparticle sliding, a mechanism that in comparison expends more energy.
Identification of Problem Gambling via Recurrent Neural Networks Predicting self-exclusion due to problem gambling within the remote gambling sector by means of recurrent neural networks

Under recent years the gambling industry has been moving towards providing their customer the possibility to gamble online instead of visiting a physical location. Aggressive marketing, fast growth and a multitude of actors within the market have resulted in a spike of customers who have developed a gambling problem. Decision makers are trying to fight back by regulating markets in order to make the companies take responsibility and work towards preventing these problems. One method of working proactively in this regards is to identify vulnerable customers before they develop a destructive habit. In this work a novel method of predicting customers that have a higher risk in regards to gambling-related problems is explored. More concretely, a recurrent neural network with long short-term memory cells is created to process raw behaviour data that are aggregated on a daily basis to classify them as high-risk or not. Supervised training is used in order to learn from historical data, where the usage of permanent self-exclusions due to gambling related problems defines problem gamblers. The work consists of: obtain a local optimal configuration of the network which enhances the performance for identifying problem gamblers who favour the casino section over sports section, and analyze the model to provide insights in the field. This project was carried out together with LeoVegas Mobile Gaming Group. The group offers both online casino games and sports booking in a number of countries in Europe. This collaboration made both data and expertise within the industry accessible to perform this work. The company currently have a model in production to perform these predictions, but want to explore other approaches. The model that has been developed showed a significant increase in performance compared to the one that is currently used at the company. Specifically, the precision and recall which are two metrics important for a two class classification model, increased by 37% and 21% respectively. Using raw time series data, instead of aggregated data increased the responsiveness regarding customers change in behaviour over time. The model also scaled better with more history compared to the current model, which could be a result of the nature of a recurrent network compared to the current model used.

Single-Word Recognition Impairments in Primary School-Aged Children with Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a group of neurodevelopmental disorders characterized by impairments in social interaction and communication as well as behavior. Usually children with ASD have comorbid language disorders and/or delay. The present study concentrated on single-word recognition in 7-to-11-year-old Russian children with ASD. The results showed that primary-school-aged children with autism have difficulties even with such a basic process as single-word recognition.
