Authors: Рыжиков  , Ryzhikov Sergey 
Published: February 2017

The work of the student on the course work is the most eff ective form to enhance and optimize the teaching and learning process, a way of strengthening his professional and applied orientation, helps to strengthen the connection of educational process with teaching and research activities, is an eff ective means of intensifying the focus of professional training of the student. To modern specialist society has a long list of requirements, among which important value has the presence of graduates of certain abilities and skills independently to extract knowledge from diff erent sources, to systematize received information, analyze the problem. The formation of such skills occurs
during the whole study period. The independent work of students plays a crucial role in the entire educational process. The implementation of the course work contributes to the formation of the subject of cognitive activity, requires the creation of a complex of pedagogical conditions for the development of sustainable, high-quality learning motivation; in it the big role self-mastery of general and professional competences. In “Lebedyansky Commerce and Economic College” is constantly working to improve the quality of education. In the long term, the criterion for assessing
the quality of the coursework should be the assessment of the degree of creativity and independence of students when performing this type of research. As creativity is based on cognitive abilities of man and covers the areas of personality, process, result, it will contribute to the development of creative elements of scientifi c knowledge, formation of professional qualities of students. The role of training coursework is particularly relevant in the present time, when educational institutions set the task of formation at students of need to continuous self-education, which supposes the ability for own cognitive activity.

Published: February 2017

We study the empirical relevance of the participation externality between liquidity suppliers (makers) and demanders (takers), i.e., whether liquidity demand attracts or reduces liquidity supply, and vice versa. We use exogenous shocks to exchange fees and technology as experiments to identify cross-sided complementarities between liquidity suppliers and demanders in the U.S. equity market. We find that the externality is large and positive, on average. However, the externality is negative in periods of high adverse selection. We quantify the economic significance of the externality by evaluating an exchange’s revenue after a fee change. The Internet appendix is available at https://doi.org/10.1287/mnsc.2016.2658 .

Information Sharing in Competing Supply Chains with Production Cost Reduction
Authors: Ha Albert Y. , Tian Quan , Tong Shilu 
Published: February 2017

We consider the problem of sharing demand information in two competing supply chains, each consisting of one manufacturer and one retailer. Information sharing allows a manufacturer’s wholesale price to respond to demand signal, which benefits the supply chain if the manufacturer is efficient in cost reduction and hurts it otherwise. It also allows a manufacturer’s cost reduction level to respond to demand signal, which always benefits the supply chain. A supply chain that engages in information sharing triggers a reaction from the rival chain. Such a reaction may benefit or hurt the first supply chain, depending on whether the retailers compete on quantity or price, and whether or not the manufacturers are efficient in cost reduction. With quantity competition, information sharing occurs when the manufacturers are efficient in cost reduction. It is more likely to occur when either information is less accurate or competition is less intense. With price competition, information sharing occurs when either competition is intense or the manufacturers are efficient in cost reduction. It is more likely to occur when information is more accurate. When information sharing is beneficial to a supply chain, a manufacturer can buy information from a retailer with a side payment, which is zero if the manufacturer is sufficiently efficient in cost reduction.The e-companion is available at https://doi.org/10.1287/msom.2016.0607 .
Ideological Heterogeneity and the Rise of Donald Trump
Authors: Carmines Edward G. , Ensley Michael J. , Wagner Michael W. 
Published: February 2017

AbstractIn the days after the 2016 election, a variety of explanations has been offered to explain Donald Trump’s unique ascendancy in American politics. Scholars have discussed Trump’s appeal to rural voters, his hybrid media campaign strategy, shifts in voter turnout, Hillary Clinton’s campaign advertising strategy, economic anxiety, differences in sexist and racist attitudes among Trump voters and so forth. Here, we add another key factor to the conversation: Trump’s appeal to a smaller, often ignored, segment of the electorate: populist voters. Building upon our previous work – demonstrating that while American political elites compete across a single dimension of conflict, the American people organize their attitudes around two distinct dimensions, one economic and one social – we use 2008 American National Elections Study (ANES) data and 2016 ANES primary election data to show that populist support for Trump, and nationalist policies themselves, help us to understand how Trump captured the Republican nomination and the White House.
Modern Eras and Alternative Futures: The American Elections of 2016 in the Longest Run
Authors: Shafer Byron E. , Wagner Regina L. 
Published: February 2017

AbstractOn the morning after, the aggregate story of the American elections of 2016 was one of surprise. Professional pundits – not to mention the pollsters, those masters of disaggregation – had been rather strikingly wrong. So, one of the major products of the elections of 2016 was a major research project for these professional disaggregators. But can those who treat elections as aggregate phenomena – as patterned wins and losses across time – fit these results into an ongoing pattern? Within this pattern, what looks familiar and what looks anomalous? Or, said the other way around, when

Published: February 2017

AbstractIn this paper, a compact via-free low pass filter is designed based on composite right/left handed (CRLH) concept. The structure uses open ended concept. Rectangular slots are etched on signal transmission line (TL) to suppress the spurious band without altering the performance and size of filter. The filter is designed for low pass frequency band with cut-off frequency of 3.5 GHz. The proposed metamaterial structure has several prominent advantages in term of selectivity up to 34 dB/GHz and compactness with average insertion loss less than 0.4 dB. It has multiple applications in wireless communication (such as GSM900, global navigation satellite system (1.559–1.610 GHz), GSM1800, WLAN/WiFi (2.4–2.49 GHz) and WiMAX (2.5–2.69 GHz)). The design parameters have been measured and compared with the simulated results and found excellent agreement. The electrical size of proposed filter is 0.14λ

Published: February 2017

AbstractThis research study attempts to create an optimized parametric window by employing Taguchi algorithm for Plasma Arc Welding (PAW) of 2 mm thick 2205 duplex stainless steel. The parameters considered for experimentation and optimization are the welding current, welding speed and pilot arc length respectively. The experimentation involves the parameters variation and subsequently recording the depth of penetration and bead width. Welding current of 60–70 A, welding speed of 250–300 mm/min and pilot arc length of 1–2 mm are the range between which the parameters are varied. Design of experiments is used for the experimental trials. Back propagation neural network, Genetic algorithm and Taguchi techniques are used for predicting the bead width, depth of penetration and validated with experimentally achieved results which were in good agreement. Additionally, micro-structural characterizations are carried out to examine the weld quality. The extrapolation of these optimized parametric values yield enhanced weld strength with cost and time reduction.

Published: February 2017

Abstract

Acinetobacter baumannii, a non-fermenting Gram-negative bacterium, is a common pathogen in intensive care units (ICU) that is easily spread through contact and can cause nosocomial outbreaks. This study investigated the risk factors associated with outbreaks of pan-drug resistant Acinetobacter baumannii (PDR-Ab) infection by studying a suspected nosocomial outbreak in a comprehensive ICU in a teaching hospital in China, and discusses the effectiveness of current prevention and control measures.
Pathogen detection methods involving pulsed field gel electrophoresis (PFGE) were employed to survey patients infected or colonized with PDR-Ab. An epidemiological investigation was conducted to determine the risk factors for infection or colonization with PDR-Ab between 1 October 2014 and 16 January 2015.
The rate of PDR-Ab infection in the ICU was higher during the period from 1 October 2014 to 16 January 2015 than it was between 1 October 2013 and 16 January 2014. Only two cases were confirmed to have the same genotype. Risk factors were explored and the rate of infection was found to be controlled by interventions targeting these risk factors.
A decrease in the number of infections was observed after multiple prevention and control measures were implemented, preventing the outbreak of a nosocomial infection.
Numerical Analysis of Exhaust Emission from an Aero Gas Turbine Combustor under Fuel-Rich Condition
Authors: Mishra R. K. , Chandel Sunil 
Published: February 2017

Abstract
Emission characteristic of an aero gas turbine combustor has been studied under fuel-rich condition. The combustor has been designed to operate at rich fuel-air mixture and may experience very high mixture up to equivalence ratio of 3.0 in the primary zone in the event of atomizer deterioration and flow passage distortion or during some maneuver. The concentration of major engine emission/pollutant constituents at combustor exhaust such as CO, NOx, soot, unburned hydrocarbons and atmospheric pollutants such as CO2 and water vapor has been analyzed at fuel-rich high equivalence ratio using computational model in CFX. The pollutant concentrations are found to be increased with increase in equivalence ratio. Atomization quality in terms of fuel droplet size is found to have a significant contribution in the concentration of various species at combustor exit.
A Negative Allosteric Modulator for α5 Subunit-Containing GABA Receptors Exerts a Rapid and Persistent Antidepressant-Like Action without the Side Effects of the NMDA Receptor Antagonist Ketamine in Mice

Published: February 2017

AbstractNew antidepressant pharmacotherapies that provide rapid relief of depressive symptoms are needed. The NMDA receptor antagonist ketamine exerts rapid antidepressant actions in depressed patients but also side effects that complicate its clinical utility. Ketamine promotes excitatory synaptic strength, likely by producing high-frequency correlated activity in mood-relevant regions of the forebrain. Negative allosteric modulators of GABA-A receptors containing α5 subunits (α5 GABA-NAMs) should also promote high-frequency correlated electroencephalogram(EEG) activity and should therefore exert rapid antidepressant responses. Because α5 subunits display a restricted expression in the forebrain, we predicted that α5 GABA-NAMs would produce activation of principle neurons but exert fewer side effects than ketamine. We tested this hypothesis in male mice and observed that the α5 GABA-NAM MRK-016 exerted an antidepressant-like response in the forced swim test at 1 and 24 h after administration and an anti-anhedonic response after chronic stress in the female urine sniffing test (FUST). Like ketamine, MRK-016 produced a transient increase in EEG γ power, and both the increase in γ power and its antidepressant effects in the forced swim test were blocked by prior administration of the AMPA-type glutamate receptor antagonist 2,3-dioxo-6-nitro-1,2,3,4-tetrahydrobenzo[f]quinoxaline-7-sulfonamide (NBQX). Unlike ketamine, however, MRK-016 produced no impairment of rota-rod performance, no reduction of prepulse inhibition (PPI), no conditioned-place preference (CPP), and no change in locomotion. α5 GABA-NAMs, thus reproduce the rapid antidepressant-like actions of ketamine, perhaps via an AMPA receptor (AMPAR)-dependent increase in coherent neuronal activity, but display fewer potential negative side effects. These compounds thus demonstrate promise as clinically useful fast-acting antidepressants.
Botanical Phylo-Cards: A Tree-Thinking Game to Teach Plant Evolution
Authors: Gibson J. Phil , Cooper Joshua T. 
Published: February 2017

Students often have limited understanding of the major innovations in plant evolution. We developed a card sorting activity based on tree thinking that is suitable for students with a wide range of abilities and experience. Through this activity, students learn how scientists organize taxa into biologically meaningful, natural groups that illustrate important events in terrestrial plant evolution. The activity corresponds to several NGSS standards and is suitable for use in classroom or laboratory settings and as a public educational outreach activity.
The Botanical Phylo-Card Game addresses several components of Next Generation Science Standards (NGSS Lead States, 2013) such as Inheritance/Variation in Traits (3-LS3-1, HS-LS3-1, HS-LS4-2) and Natural Selection/Evolution (MS-LS4-2, HS-LS4-1). The game involves disciplinary core ideas about biodiversity, evolution, and common ancestry; crosscutting concepts regarding identification and interpretation of patterns; and scientific practices of constructing explanations and engaging in arguments from evidence that can guide individualized implementation and assessment of the activity by different instructors.
Primary adrenal insufficiency is associated with impaired natural killer cell function: a potential link to increased mortality
Authors: Bancos Irina , Hazeldine Jon , Chortis Vasileios , Hampson Peter , Taylor Angela E , Lord Janet M , Arlt Wiebke 
Published: February 2017

Objective
Mortality in patients with primary adrenal insufficiency (PAI) is significantly increased, with respiratory infections as a major cause of death. Moreover, patients with PAI report an increased rate of non-fatal infections. Neutrophils and natural killer (NK) cells are innate immune cells that provide frontline protection against invading pathogens. Thus, we compared the function and phenotype of NK cells and neutrophils isolated from PAI patients and healthy controls to ascertain whether altered innate immune responses could be a contributory factor for the increased susceptibility of PAI patients to infection.

Design and methods
We undertook a cross-sectional study of 42 patients with PAI due to autoimmune adrenalitis (n = 37) or bilateral adrenalectomy (n = 5) and 58 sex- and age-matched controls. A comprehensive screen of innate immune function, consisting of measurements of neutrophil phagocytosis, reactive oxygen species production, NK cell cytotoxicity (NKCC) and NK cell surface receptor expression, was performed on all subjects.

Results
Neutrophil function did not differ between PAI and controls. However, NKCC was significantly reduced in PAI (12.0 ± 1.5% vs 21.1 ± 2.6%, P < 0.0001). Phenotypically, the percentage of NK cells expressing the activating receptors NKG2D and NKp46 was significantly lower in PAI, as was the surface density of NKG2D (all P < 0.0001). Intracellular granzyme B expression was significantly increased in NK cells from PAI patients (P < 0.01).

Conclusions
Adrenal insufficiency is associated with significantly decreased NKCC, thereby potentially compromising early recognition and elimination of virally infected cells. This potential impairment in anti-viral immune defense may contribute to the increased rate of respiratory infections and ultimately mortality in PAI.
