Biochemical responses to horror, or, ‘why do we like this stuff?’
Authors: Pendery David R.
Published: May 2017

‘Biochemical responses to horror, or, “Why do we like this stuff?”’ analyses human’s enigmatic interest in horror narrative. Analyses to date have been oversimplified, and overlook essential conditions and responses that take place during the consumption of horror narrative. A key misunderstanding is that the central question of the interest in horror is understood to be ‘Why do we find gratification in what by nature is so disturbing and disagreeable?’ This approach overweighs the enjoyment that horror consumers feel, and ignores the fear response. The fear response is the starting point of any analysis of human interest in horror. This key emotional reaction is tightly linked to goal-directed, advanced cognition in humans, with these conditions functioning in feedback looping mechanisms in human psychology and physiology. This interplay is further conditioned within a framework of socio-biological conditions and adaptive pressures. The socio-biological framework and adaptive pressures yield other effects in human personality and society that also condition and add elements to the human interest in horror narrative. I argue that the most precise and comprehensive explanation of human interest in horror narrative is a sundry synthesis of scientific and sociological fundamentals.

Cutting through the fourth wall: The violence of home invasion in Michael Haneke’s Funny Games
Authors: Fiddler Michael
Published: May 2017

The home is central to the western imaginary. It is of foundational importance to the shaping of identity. It is where we begin to construct the story of ourselves and where we first learn to navigate space. Yet, it is also a site of shadows and fear, of hidden desires and ambivalence. Within the cinematic home invasion genre, this is heightened by the presence of an antagonistic Other. They render all categorically interstitial. As with the Lacanian notion of extimité, the invading Other confuses interior and exterior boundaries. In Michael Haneke’s (1997 original and 2007 remake) Funny Games, this is further problematized by the lead antagonist’s movement between the diegetic world and that of the viewer. This article examines this fourth wall breaking and unpacks how the audience’s consumption of violent media is critiqued as the lines between the home of the film and that of the viewing audience become blurred.
‘House of mirrors’: The sentient house as homosocial space in Andrew Pyper’s The Guardians
Authors: Mayr Suzette
Published: May 2017

In The Poetics of Space ([1958] 1969), Gaston Bachelard proposes that ‘The house is a “psychic state”’, and focuses on the childhood house – specifically ‘the house we were born in’ – because he believes that with this ‘first’ house one establishes a ‘passionate liaison’. Andrew Pyper’s novel The Guardians (2011) is ostensibly a haunted house novel about four men battling a malevolent house, but the novel is also about the unique love the men express for and with each other – what masculinity scholars Hammarén and Johansson would label ‘horizontal homosociality’ or ‘a more sensitive and intimate masculinity’. Ultimately, the malevolent house provides the only venue in which the men can express this intimate love for each other. I argue that the house’s relationship with the men is, fundamentally, a ‘passionate liaison’; for while the men were not born in the house and so it is not literally their ‘first’ house, the house forces key rites of passage that bind the men and the house together forever. With the house’s destruction at the novel’s conclusion the male relationships are constrained and hollowed out by hegemonic masculine expectations and stereotypes.
Empagliflozin: a new strategy for nephroprotection in diabetes
Authors: Korbut Anton Ivanovich , Klimontov Vadim Valer'evich
Published: May 2017

Empagliflozin, an inhibitor of sodiumglucose symporter type 2 (SGLT2), is a new class of antidiabetic agents with numerous pleiotropic effects. The review summarises data on the influence of empagliflozin on the structural and functional changes in the kidneys of the models of diabetes mellitus (DM) and of patients with DM. A literature search was conducted using the databases of Medline/PubMed, Scopus, Web of Science, ClinicalTrials.gov and eLibrary. The experimental results showed a decrease in the blood glucose level, blood pressure, glomerular hyperfiltration and overexpression of proinflammatory and fibrogenic factors in the kidneys under the influence of empagliflozin. Most clinical studies have demonstrated the albuminuria-lowering effect of empagliflozin in patients with type 2 DM. The EMPA-REG OUTCOME study has demonstrated slowing of the chronic kidney disease progression, decrease in the incidence of end-stage renal failure and death from renal causes in patients with type 2 DM undergoing the empagliflozin treatment compared with those receiving placebo. The mechanisms of the nephroprotective effect of empagliflozin included systemic and renal effects. The decrease in hyperglycaemia, blood pressure and body weight; reduction in glomerular hyperfiltration; enhancement of sodium excretion and suppression of inflammatory and fibrogenic signalling pathways in the kidneys may help slow the development of diabetic kidney damage under the influence of empagliflozin. The possibility of extrapolating the confirmed properties of empagliflozin to other SGLT2 inhibitors needs further investigation.
The Kumaraswamy compound Rayleigh distribution : properties and estimation
Authors: Reyad Hesham , Othman Soha A. , Younis Adil M , Hashish Ahmed M.
Published: May 2017

We introduce a new four parameter continuous model, called the Kumaraswamy compound Rayleigh (KwCR) distribution that extends the compound Rayleigh distribution. We study some mathematical properties of this distribution such as; mean, variance, coefficient of variation, quantile function, median, ordinary and incomplete moments, skewness, kurtosis, moment and probability generating functions, reliability analysis, Lorenz, Bonferroni and Zenga curves, RÃ©nyi of entropy, order statistics and record statistics. We consider the methods of moments and maximum likelihood for estimating the model parameters.

Published: May 2017

This study aimed to determine prevalence of postpartum dyspareunia and related factors.In cross-sectional and descriptive study, a questionnaire was used to collect data. Universe of the study was composed of all women in the first postpartum one year, Sampling consisted of 246 women in postpartum one-year period admitted to public healtcare centers in Konya, Turkey.While the rates of experiencing dispareunia were 20.8% in prenatal period, 22.9% during pregnancy and 36.6% in the first intercourse after delivery, the rate was found as 41.5%  in postpartum period. According to the results of logistic regression analysis; decision given by partners to start intercourse, worrying about intercourse, having challenges with the partner and experiencing dispareunia during pregnancy were found to be important risk factors. Dyspareunia seems to be a major challenge affecting the sexual life of women in postpartum period. During postpartum follow-ups, and training and counseling may be suggested.
The Differential Impact of New Product Development “Make/Buy” Choices on Immediate and Future Product Quality: Insights from the Automobile Industry
Authors: Kalaignanam Kartik , Kushwaha Tarun , Swartz Tracey A.
Published: May 2017

This article examines the impact of new product development (NPD) “make/buy” choices on product quality using data from the automobile industry. Although the business press has lamented that NPD outsourcing compromises product quality, there is no systematic evidence to support or refute this assertion. Against this backdrop, this study tests a contingency model of the impact of NPD make/buy decisions on immediate and future product quality. The hypotheses are tested using data on NPD make/buy choices of 173 models of 12 automobile firms in the United States between 2007 and 2014. The authors find that whereas NPD buy has a more positive impact on immediate product quality, NPD make has a more positive impact on future product quality. Furthermore, the immediate product quality impact of NPD buy is stronger when (1) technologies are more complex and (2) firm NPD capability is higher. In contrast, the future product quality impact of NPD make is stronger when (1) there is postlaunch adverse feedback and (2) firm NPD capability is higher. The study highlights the complex trade-offs associated with NPD make/buy decisions and offers valuable insights on how firms could manage these decisions.
Demand for “Healthy” Products: False Claims and FTC Regulation
Authors: Rao Anita , Wang Emily
Published: May 2017

Firms sometimes make selective or deceptive claims, which can have negative consequences for consumers, especially if consumers are not fully informed and the claims are hard to verify. This study aims to measure the decline in demand that a firm making such claims faces when caught. In addition, it seeks to understand which type of consumer these claims primarily affect. Using a panel data set of consumer purchases and firm advertising, the authors measure this impact by exploiting the fact that four popular products settled charges raised by the Federal Trade Commission. They further control for and document firm responses in terms of price and advertisement changes around the date of the settlement. Findings indicate a significant decline in demand following the termination of the claims, resulting in a 12%–67% monthly loss in revenue across the four products, which amounts to a $.40 million–$3.82 million loss in monthly revenue. They also find that these claims primarily affect consumers who are newcomers.

The paper discusses a representation of modes (idempotent and entropic algebras) as subalgebras of so-called functorial sums of cancellative algebras. We show that each mode that has a homomorphism onto an algebra satisfying a certain additional condition, with corresponding cancellative congruence classes, embeds into a functorial sum of cancellative algebras. We also discuss typical applications of this result.
Embedding modes into semimodules, Part III
Authors: Pilitowska Agata , Romanowska Anna B.
Published: May 2017

In the first part of this paper, we considered the problem of constructing a (commutative unital) semiring defining the variety of semimodules whose idempotent subreducts lie in a given variety of modes. We provided a general construction of such semirings, along with basic examples and some general properties. In the second part of the paper we discussed some selected varieties of modes, in particular, varieties of affine spaces, varieties of barycentric algebras and varieties of semilattice modes, and described the semirings determining their semi-linearizations, the varieties of semimodules having these algebras as idempotent subreducts. The third part is devoted to varieties of differential groupoids and more general differential modes, and provides the semirings of the semi-linearizations of these varieties.

Common fixed point theorems for variants of R-weakly commuting mappings in topologically complete Tychonoff (uniform) spaces
Authors: Kohli J. K. , Kumar Durgesh
Published: May 2017

Three variants of R-weakly commuting mappings in the realm of uniform spaces are defined. Examples are included to reflect upon the distinctiveness of the notions so defined. Common fixed point theorems concerning these variants of R-weakly commuting mappings in the framework of uniform spaces are obtained. This generalizes several known results in the literature including those of Granas and Dugundji [3], Tarafdar [12] and others. Moreover, as a bi-product we obtain several common fixed point theorems which are well in contrast with a common fixed point theorem of Jungck [4] who proved the same for commuting mappings.
A lower bound on the double outer-independent domination number of a tree

A vertex of a graph is said to dominate itself and all of its neighbors. A double outer-independent dominating set of a graph G is a set D of vertices of G such that every vertex of G is dominated by at least two vertices of D, and the set V (G) \ D is independent. The double outer-independent domination number of a graph G, denoted by

A zero-sum competitive multi-player game
Authors: Guo Ivan , Rutkowski Marek
Published: May 2017

A single period, zero-sum, multi-player game is constructed. Each player can either exit the game for a fixed payoff or stay and split the remaining payoff with the other non-exiting players. The emphasis is put on the rivalrous nature of the payoffs, meaning that the sum of all payoffs is fixed, but the exact allocation is based on the players’ decisions. The value at which Nash and optimal equilibria are attained is shown to be unique and it is constructed explicitly.
On general optimal stopping problems using penalty method

In the paper we use penalty method to approximate a number of general stopping problems over finite horizon. We consider optimal stopping of discrete time or right continuous stochastic processes, and show that suitable version of Snell’s envelope can by approximated by solutions to penalty equations. Then we study optimal stopping problem for Markov processes on a general Polish space, and again show that the optimal stopping value function can be approximated by a solution to a Markov version of the penalty equation.

Basic properties of quasi cl-supercontinuous functions are studied and their place in the hierarchy of variants of continuity that already exist in the mathematical literature is elaborated. The notion of quasi cl-supercontinuity, in general, is independent of continuity but coincides with cl-supercontinuity (≡ clopen continuity) (Applied General Topology 8(2) (2007), 293–300; Indian J. Pure Appl. Math. 14(6) (1983), 767–772), a significantly strong form of continuity, if range is a regular space. The class of quasi cl-supercontinuous functions properly contains each of the classes of (i) quasi perfectly continuous functions and (ii) almost cl-supercontinuous functions; and is strictly contained in the class of quasi z-supercontinuous functions. Moreover, it is shown that if X is sum connected (e.g. connected or locally connected) and Y is Hausdorff, then the function space Lq
(X, Y) of all quasi cl-supercontinuous functions as well as the function space Lδ
(X, Y) of all almost cl-supercontinuous functions from X to Y is closed in YX
in the topology of pointwise convergence.

\font\msbm=MTMIB${\msbm E}_1^n $

. In (n − 1)-dimensional space we construct a model for these directions by means of concepts characteristic of Euclidean geometry. Because it is a pseudo-orthogonal group, not orthogonal, that operates in this model, the distance between two points and the measure of an angle are not invariants. Using these changeable quantities we construct invariant quantities.
Well-posedness and common fixed points for two pairs of maps using weak contractivity
Authors: Akkouchi Mohamed
Published: May 2017

In 2006, I. Beg and M. Abbas have studied the existence of coincidence and common fixed points for two mappings satisfying a weak contractive condition. Their results were extended in 2008 by A. Azam and M. Shakeel to the case of three mappings. Recently M. Abbas and D. Dorić employed the contractive conditions introduced in [Q. Zhang and Y. Song, Fixed point theory for generalized ϕ-weak contraction, Appl. Math. Lett. 22(2009), 75-78] and [D. Dorić, Common fixed point for generalized (ψ, ϕ)-weak contractions, Appl. Math. Lett. 22 (2009), 1896–1900] to prove a common fixed point theorem for four mappings satisfying generalized weak contractive condition (see Filomat 24:2 (2010), 1–10). In this paper, we generalize this theorem by using the concept of common property (E.A). Our result generalizes and unifies several existing results involving generalized weak contractive conditions. We study also well-posedness of a related fixed point problem.

Some examples of denumerable pseudo-ordered fields and their applications to geometry
Authors: Jakóbowski Jan
Published: May 2017

The paper deals with the following problems concerning pseudo-ordered denumerable fields:

(i)

a connection between Fermat’s two squares theorem and the unique pseudo-order in a finite field;

(ii)

properties of a proper pseudo-order determined by any prime number in the field of rational numbers;

(iii)

existence of a proper pseudo-order in every subfield of the sequence used to obtain the field of constructible numbers;

(iv)

some brief of applications of the latter pseudo-orders to construct new algebraic and geometric structures.

In particular, we extend the known construction of finite nearfields or quasifields given by e.g. W. A. Pierce or P. Dembowski – to infinite cases.

Authors: Choudhury Binayak S. , Kundu Amaresh
Published: May 2017

In this paper, we have introduced a generalised Kannan type contraction. It has been established that such mappings necessarily have fixed points in a complete partially ordered metric space. The fixed point is unique under some additional conditions. The result is illustrated with an example. The work is in the line of research in fixed point theory on ordered metric structures.
Effective energy integral functionals for thin films in the Orlicz–Sobolev space setting
Authors: Laskowski Włodzimierz , Nguyen Hong Thai
Published: May 2017

We consider an elastic thin film as a bounded open subsetωof ℝ2. First, the effective energy functional for the thin filmωis obtained, by Г-convergence and 3D-2Ddimension reduction techniques applied to the sequence of re-scaled total energy integral functionals of the elastic cylindersω×(-ε2,ε2)$\omega \times \left( { - {\varepsilon \over 2},{\varepsilon \over 2}} \right)$as the thicknessεgoes to 0. Then we prove the existence of minimizers of the film energy functional. These results are proved in the case when the energy density function for the elastic cylinders has the growth prescribed by an Orlicz convex functionM. HereMis assumed to be non-power-growth-type and to satisfy the conditions ∇2and ∇2(that is equivalent to the reflexivity of Orlicz and Orlicz–Sobolev spaces generated byM). These results extend results of H. Le Dret and A. Raoult for the caseM(t) = |t|pfor somep∈ (1, ∞).

The biology of JC polyomavirus
Authors: Assetta Benedetta , Atwood Walter J.
Published: May 2017

JC polyomavirus (JCPyV) is the causative agent of a fatal central nervous system demyelinating disease known as progressive multifocal leukoencephalopathy (PML). PML occurs in people with underlying immunodeficiency or in individuals being treated with potent immunomodulatory therapies. JCPyV is a DNA tumor virus with a double-stranded DNA genome and encodes a well-studied oncogene, large T antigen. Its host range is highly restricted to humans and only a few cell types support lytic infectionin vivoorin vitro. Its oncogenic potential in humans has not been firmly established and the international committee on oncogenic viruses lists JCPyV as possibly carcinogenic. Significant progress has been made in understanding the biology of JCPyV and here we present an overview of the field and discuss some important questions that remain unanswered.
Gridable Electric Vehicle (GEV) Aggregation in Distribution Network to Support Grid Requirements: A Communication Approach
Authors: Hampannavar Santoshkumar , Chavhan Suresh , Yaragatti Udaykumar , Naik Anant
Published: May 2017

Electric Vehicles (EV) can be connected to the grid for power transaction and also serve as distributed resource (DR) or distributed energy storage system (DESS). The concept of connecting group of EVs or gridable EVs (GEV) to the grid is called Vehicle-to-Grid (V2G). V2G is a prominent energy storage system as it is flexible and can be used to support the grid requirements in order to meet the time varying load demand. Optimal placement of GEV aggregation in power distribution network is very challenging and helps in maintaining stability of the power system for a shorter duration of time. In this paper, algorithm is developed for estimating parameters like Ploss, Qloss, Vpu based on past history and wireless access support for Control and Monitoring Unit (CMU) to aggregator agent communication is proposed using Long Term Evolution (LTE) protocol. The load flow studies are carried using MiPOWER software in order to obtain the optimal location for the placement of GEV aggregation in power distribution network. LTE physical layer is modeled using MATLAB/SIMULINK and the performance is analyzed using bit error rate (BER) v/s signal to noise ratio (SNR) curves.
