Published: February 2019

The ordered mesoporous Mg- and Ni-Mg-alumina samples of general formula xwt%Mg-Al2O3 and ywt%Nixwt% Mg-Al2O3(x, y = 5, 10 % wt) have been prepared by the one-pot evaporation induced self-assembly (EISA) method using Pluronic P123 as a template. The textural and structural properties of the prepared samples have been characterized by N2adsorption-desorption analysis, BET, XRD, TEM with EDX, HAADF-STEM, and H2-TPR. The samples calcined at 700°C had an ordered mesoporous structure with a SSA of 170-250 m2/g, a pore volume of 0.5-0.64 cm3/g and a narrow distribution of the pore size (mean 12-16 nm). For the catalysts prepared by the one-pot EISA method, the size of the metal Ni particles was in the range of 3-12 nm and was conditioned by their confinement in the mesopores and the interaction with MgO and Al2O3. Testing in methane dry reforming in the 15v.% CH4+ 15v.%CO2feed, with He balance, at 650-750°C and the contact time of 0.015 s has shown the higher activity and stability of the ordered mesoporous 10w%Ni- 10w%Mg-Al2O3catalysts prepared by the one-pot method as compared with the catalyst of the same composition obtained by impregnation.

Published: February 2019

This paper studies the problem of data access at the receiver with large bit error rate and low quality factor. Due to this issue the information got inaccurately at the receiver side, the data should have high quality factor and low bit error rate to be simple of identification at the receiver when using the gates. The nonlinear properties of the semiconductor optical amplifier are utilized to accomplish the Boolean variable based math work, in which AND, NAND, and OR gates potentially used to endorse the Boolean function. Through blend this gates together any Boolean function can be accomplished and utilized to perform optical signal processing. The quality factor and BER are measured by utilizing the eye diagram analyzer, the state of the output bit and also shaped by the oscilloscope visualizer in optiwave simulation program. These models can be used for wavelength converter, header recognition, parity checking, binary addition, packet-header modification, encoding and encryption with pattern matching, and data encryption with high speed and high quality factor.

Authors: Wang Baomin , Guo Baolin , Han Yu , Zhang Yuan , Li Yang
Published: February 2019

In this work, the properties of carbon nanofiber (CNF)-reinforced cement composites, including the microstructure and high-toughness performance, were investigated. The aqueous dispersing method was used along with a common surfactant and ultrasonic processing in order to obtain homogenous distributed CNF suspensions. The weight fractions of incorporated CNFs in the cement matrix were set to be 0, 0.5, 0.075, 0.1, 0.125, and 0.15 %. A high-toughness performance test, nanoindentation process, and scanning electron microscopy were used to characterize the reinforcement of CNFs in cement composites. Compared with the plain specimen, the addition of CNFs can improve the toughness performance, Young’s modulus, hardness, and microstructure of cement composites. The 0.1 % weight fraction of CNFs obtained the maximum reinforcement among all the tested specimens. The embedded CNFs acted as bridges and networks across the voids and cracks in the matrix, which guaranteed the load transfer in tension. It is noted that the load transfer can be enhanced by embedding CNFs as bridges and networks across the voids and cracks in the composite matrix.

Authors: Kolhatkar Ashish , Karthik V. , Chaitanya G. M. S. K. , Kumar Anish , Ramchandran Divakar
Published: February 2019

In this work, a miniature tensile specimen with nominal dimensions of 3.0-mm gage length (GL), 1.5-mm gage width, and 0.5-mm thickness that was carved out of a 10.0-mm-diameter disk has been developed and standardized using analytical and experimental methods. The geometry of the miniature specimen, called ultra sub-size (USS), was optimized using finite element analysis to determine the fillet radius and appropriate geometrical tolerances for specimen dimensions like gage width and thickness. The methods of specimen preparation, gripping, and tensile testing with the use of digital image correlation for strain measurement were standardized. The 0.2 % offset yield strength, ultimate tensile strength, and uniform strain of different materials obtained using this specimen geometry were analyzed and compared with the results of ASTM sub-size (GL: 25 mm) and further sub-size geometry (GL: 12.5 mm). The results of this study show that USS tensile specimen geometry developed in this work can be reliably employed for mechanical property evaluation in situations where tensile testing using standard-size specimens is practically not possible.
Effect of Tool Pin Profile on Microstructure and Hardness of Magnesium Alloy Zk60/SiCp Surface Composites Fabricated by Friction Stir Processing
Authors: Vignesh Kumar M. , Padamanaban G. , Balasubramanian V.
Published: February 2019

The combination of stiffness, good castability, high specific strength, and low density makes magnesium alloys ideal materials, particularly in lightweight structural applications. The two major drawbacks of magnesium alloys are poor friction and wear resistance, because they restrict the structural applications. Therefore, it is necessary to enhance the tribological properties of magnesium alloys without creating many adverse effects on the properties of the base metal by using surface engineering. In order to achieve a sound fabrication of surface metal matrix composites on the magnesium plate, friction stir processing (FSP) often serves as a good candidate. However, the process parameters should be suitably selected to fabricate a sound FSP zone. Tool pin profile is a major significant process parameter, particularly in FSP, as it plays major part in the formation of a processed region with a uniform distribution of reinforcement particles. In this study, an attempt was made to understand the major effects of tool pin profiles, namely, cylindrical thread, plain cylindrical, plain tapered cylindrical (PTC), and square on the microstructure characteristics and particle distribution of FSP ZK60/Silicon Carbide particle (SiCp) surface composites. Of the four pin profiles, surface composites fabricated by means of PTC pin profile resulted in a defect-free and higher hardness processed zone. This was attributed to the higher shear force offered by the PTC pin profile, which aids proper material flow with evenly distributed particles.

Authors: Shi Pengcheng , Dai Zhen , Zhu Hong , Gao Qiju , Li Xinsheng , Shen Junan
Published: February 2019

The nanoscaled properties including morphology and mechanics of recovered asphalt binders from open-graded friction course (OGFC) asphalt mixtures weathered in a laboratory were measured by atomic force microscopy. In addition, specific functional groups and molecular size distributions of the recovered binders were tested by Fourier infrared spectroscopy and gel permeation chromatography (GPC), respectively. The OGFC mixtures were weathered in an accelerated weathering machine for various durations of 0, 1,000, 2,000, and 3,000 h. The results showed that (1) as the weathering degree increased, the root mean square of morphology increased, and both the number of the “bee-structures” and the adhesion decreased; (2) as the weathering degree increased, the carbonyl and sulfoxide indexes increased, whereas the butadiene-based index decreased; and (3) the large molecular size groups from GPC tests increased, whereas the small molecular size groups decreased, as the weathering time increased. The changes of the molecular size groups had fairly good linear correlations with the weathering time.

Authors: Schultebraucks Katharina , Duesenberg Moritz , Di Simplicio Martina , Holmes Emily A. , Roepke Stefan
Published: February 2019

A better understanding of suicidal behavior is important to detect suicidality in at-risk populations such as patients with borderline personality disorder (BPD), posttraumatic stress disorder (PTSD), and major depressive disorder (MDD). Suicidal tendencies are clinically assessed by verbal thoughts rather than by specifically asking about mental images. This study examines whether imagery and verbal thoughts about suicide occur and differ between patients with BPD with and without comorbid PTSD compared to patients with MDD (clinical controls). All patient groups experienced suicide-related images. Patients with BPD with comorbid PTSD reported significantly more vivid images than patients with MDD. Severity of suicidal ideation, number of previous suicide attempts, and childhood traumata were significantly associated with suicidal imagery across all patient groups. The authors demonstrate for the first time that suicide-related mental imagery occurs in BPD and is associated with suicidal ideation. This finding highlights the importance of assessing mental imagery related to suicide in clinical practice.
Vandalism and Resistance in Republican Rome
Authors: Davies Penelope J. E.
Published: February 2019

As political unrest seethed in late Republican Rome, a series of violent acts were perpetrated against well-known buildings, public and private, by the people (the plebs) and their elected representatives, the tribunes. On the rare occasions when scholars mention these events, they tend to treat them as random, isolated acts of vandalism; conspicuously missing is any accounting for them in commentaries on Rome's built environment. In Vandalism and Resistance in Republican Rome, Penelope J. E. Davies assesses these acts against a broad spectrum of political activism over the ages, as well as in the narrower context of contemporaneous politics, when strict, exclusionary norms governed the sponsorship of public architecture. She argues that the destructive acts were, in fact, deliberate, ideologically driven attempts by Rome's less powerful to defy and circumvent the language of power established by the dominant class.

TRANSDISCIPLINARY – MODERN EDUCATIONAL TECHNOLOGY INTEGRATION OF KNOWLEDGE
Authors: Solodova E. A. , Efimov Р. P.
Published: February 2019

The article is concerned with the new educational technology, based on the principle of transdisciplinarity aimed at implementing the strategy of “efficient pedagogics” in the era of the hyperbolic growth of information. The essence of transdisciplinarity is the idea of methodological knowledge acquisition, invariable for a number of disciplines. The authors advocate a view that one of the transdisciplinarity central concepts is the concept of “subjectivity” of modern scientific knowledge in general and pedagogy in particular. Based on provided examples of use of transdisciplinary knowledge in engineering and pedagogical disciplines the paper shows that transdisciplinarity technology can be successfully used in any discipline.
Ethical dilemmas and moral muteness in the HRM profession
Authors: Csillag Sára
Published: February 2019

What does ethics mean in human resource management (HRM)? In this paper, based on the results of action research projects conducted with the participation of 76 HR experts in five groups, we provide insights into two issues. First we identify the most common dilemma-patterns in HRM activities in present-day Hungary (dismissal, disciplinary actions, recruitment and organizational culture). Then, we move on to the reasons for moral silence as identified by HRM experts (among others, a lack of ethical knowledge, the lifelessness of the ethical institutional framework, ignorance and fear, power games and buck-passing).

Spain, Germany, and the Holocaust: Uniting Global Learning and Student Philanthropy through Transdisciplinarity
Authors: Larson Kajsa C. , Fieler Andrea
Published: February 2019

While the atrocities of the Holocaust have been well documented, this catastrophic event has been commonly studied through the lens of a single discipline. In a course co-taught by German and Spanish professors in conjunction with the 70th anniversary of the liberation of WWII concentration camps, advanced students of German and Spanish at Northern Kentucky University engaged with this topic by analyzing, comparing, and contrasting the German-Dutch (Anne Frank) and Spanish-French (Jorge Semprún) experience. To deepen students’ cross-collaboration, the two classes engaged in a philanthropy project called the Mayerson Student Philanthropy Project. The class received a $2,000 grant, researched and advocated for local nonprofits that addressed topics related to the Holocaust, and collectively decided on the final grant recipient. This article discusses the course structure, objectives, and outcomes of a transdisciplinary approach to literature, along with student feedback about the experience.
Filipino English Teachers in Japan: “Nonnativeness” and the Teaching and Learning of English
Authors: Balgoa Nelia G.
Published: February 2019

A feature of the Japan Exchange and Teaching (JET) Program, which aims to internationalize Japan and to improve the English-speaking ability of its students, is the hiring of Assistant Language Teachers (ALTs) who are described by the Japanese government as native-level speakers of English working in Japanese classrooms. By using critical applied linguistic which focuses on questions of power, difference, access and domination in the use of the English language (Pennycook, 2001), this paper examines the motivations of the Filipino teachers as ALTs, the processes of international teacher recruitment and how their 'nonnativeness' reconfigure their identity as nonnative English speaker teachers (NNESTs) and Filipino migrants. Data from in-depth interviews and focus group discussions of Filipino ALTs and Japanese teachers show that English is both motivation and vehicle for migration and settlement for the Filipino teachers. “Nonnativeness” requires from them reconfiguration of their identity which entails them to sound native, counteract perceived forms of discrimination and assess their roles in the spread and use of English. This “nonnativeness” is a repudiation of their skills and qualifications as English teachers thus, paving the way for an interrogation of language ideologies, and of linguistic and racial identities.

Intertextualities in English Writing of EFL Learners in the Context of Chinese University
Authors: Hu Yuanyan
Published: February 2019

When the writing subject is communicating with the addressee, their texts simultaneously communicate with the present and the past texts. The author carries out an empirical study to find out issues to be addressed in the context of Chinese university in EFL learners’ English writing with respect to intertextuality. The study examines the manifestations of three types of intertextualities---material intertextuality, generic intertextuality and cultural intertextuality and finds out that there are obvious material intertextualities between students’ individualized texts and exterior texts. Certain generic intertextualities manifesting in the repetition of specific structures are deficient. And in terms of cultural intertextuality, it is found that the exterior texts have exerted an obvious cultural intertextual influence on activating pertinent schema texts of participants, promoting the comprehension of the writing theme as well as further affecting the completions of their writings.

Modeling the Dynamics of Predator-Prey Community with Age Structures
Authors: Neverova G.P. , Zhdanova O.L. , Frisman E.Ya.
Published: February 2019

A model of the predator-prey community has been proposed with specific stages of individual development and the seasonality of breeding processes.
It is assumed each of the species has an age structure with two stages of development. The case typical for the community “Arctic fox – rodents” is modeled.
An analytical and numerical study of the model proposed is made. It is shown that periodic, quasi-periodic and chaotic oscillations can occur in the system,
as well as a shift in the dynamics mode as a result of changes in the current sizes of the community’s populations. The model proposed demonstrates long-period
oscillations with time delay like auto-oscillations in the classical model of Lotka-Volterra. It is shown that a transition from stable dynamics to quasi-periodic
oscillations and vise verse is possible in the system, while an increase in the values of the half capturing saturation coefficient reduces the possibility of
quasiperiodic oscillation emergence. Simulations demonstrate the growth in predator’s consumption of the prey average number expands the zones of multistability
and quasi-periodic dynamics in the stability area of nontrivial fixed point. Therefore, the variation of the current population size of the community can lead
to a change in the dynamic mode observed. The scenarios of transition from stationary dynamics to community’s population fluctuations are analyzed with different
values of population parameters determining the dynamics of both species and their interaction coefficient. The model shows both sustainable community development
and various complex fluctuations of interacting species. At the same time, the prey dynamics affects the predator one: the prey population fluctuations initiate
predator oscillations like prey’s fluctuations, while the intrapopulation parameters of the predator can give to both stationary and fluctuating dynamic modes.
Audience-Centric Engagement, Collaboration Culture and Platform Counterbalancing: A Longitudinal Study of Ongoing Sensemaking of Emerging Technologies
Authors: Chua Sherwin , Westlund Oscar
Published: February 2019

Digital journalism studies have done little in terms of studying longitudinally the interrelationships between emerging technology and convergent news practices. This study addresses that void by using a sensemaking approach to examine how emerging technology was appropriated and enacted in the convergent news activities of newsworkers, and how they made sense of the emerging technologies over two and a half years. Our study analyzes two newsrooms in Singapore: 1) a digital-first legacy newspaper, and 2) an independent digital-only news startup. This article employs the Infotendencias Group’s (2012) analytical framework and its four dimensions of news convergence: i) business, ii) professional, iii) technological, and iv) contents. Additionally, it proposes and employs a fifth dimension: v) audience-centric engagement. The fifth dimension is based on the concept of “measurable journalism” (Carlson, 2018), analyzing how its actors influence the relationship between newsrooms and their audiences. This study builds on two rounds of in-depth interviews conducted from end-2015 to mid-2016, and again in 2018. Our findings show that audience-centric-engagement practices are observed in all four dimensions of convergent news activities of each news organization, and leads to three main conclusions: 1) the growing significance of audience-centric engagement, 2) an emergence of a collaboration culture, and 3) the salience of platform counterbalancing.
Insularized Connectedness: Mobile Chat Applications and News Production
Authors: Agur Colin
Published: February 2019

Focusing on recent political unrest in Hong Kong, this article examines how mobile chat applications (e.g., WhatsApp, WeChat, LINE, Facebook Messenger and others) have permeated journalism. In Hong Kong, mobile chat apps have served as tools for foreign correspondents to follow stories, identify sources, and verify facts; they have also helped reporting teams manage large flows of multimedia information in real-time. To understand the institutional, technological, and cultural factors at play, this article draws on 34 interviews the author conducted with journalists who use mobile chat apps in their reporting. Building on the concept of media logic, the article explores technology-involved social interactions and their impact on media work, while acknowledging the agency of users and audiences within a cultural context. It argues that mobile chat apps have become hosts for a logic of connectedness and insularity in media work, and this has led to new forms of co-production in journalism.
Distributed-lag Linear Structural Equation Models in R: the dlsem Package
Authors: Magrini Alessandro
Published: February 2019

In this paper, an extension of linear Markovian structural causal models is introduced,called distributed-lag linear structural equation models (DLSEMs),where each factor of the joint probability distribution is adistributed-lag linear regression with constrained lag shapes.DLSEMs account for temporal delays in the dependence relationshipsamong the variables and allow to assess dynamic causal effects.As such, they represent a suitable methodology to investigate the effectof an external impulse on a multidimensional system through time.In this paper, we present the dlsem package for Rimplementing inference functionalities for DLSEMs.The use of the package is illustrated through an example on simulated dataand a real-world application aiming at assessing the impact of agriculturalresearch expenditure on multiple dimensions in Europe.
A Estimation of Stochastic Volatility Models Using Optimized Filtering Algorithms
Authors: Infante Saba , Luna Cesar , Sanchez Luis , Hernández Aracelis
Published: February 2019

In this paper, we describe and implement two recursive filtering algorithms, the optimized particle filter, and the Viterbi algorithm, which allow the joint estimation of states and parameters of continuous-time stochastic volatility models, such as the Cox Ingersoll Ross and Heston model. In practice, good parameter estimates are required so that the models are able to generate accurate forecasts. To achieve the objectives the proposed algorithms were implemented using daily empirical data from the time series of the $S\&P500$ returns of the stock exchange index. The proposed methodology facilitates computational calculations of the marginal likelihood of states and allows the reconstruction of unknown states in a suitable way, and reliable estimation of the parameters. To measure the quality of estimation of the algorithms, we used the square root of the mean square error and relative deviation standard as measures of goodness of fit. The estimated errors are insignificant for the analyzed data and the two models considered. We also calculated the execution times of the algorithms, demonstrating that the Viterbi algorithm has less execution time than the optimized particle filter.

Published: February 2019

In this article the authors have considered and summarized results of previous scientific studies as well as some actual events and issues of comprehensive evaluation of determinants and factors of influence in particular on the development of international or domestic e-commerce. With the use of the system analysis e-commerce activities have been considered as a result of interactions between endogenous and exogenous environmental factors. Exogenous determinants of the international electronic commerce include micro- and macroenvironmental determinants. The microenvironmental determinants define a system of relations among consumers, competitors, potential competitors including manufacturers of substitutes, suppliers and intermediators.
The macroenvironmental determinants are represented by economical, political and legal, scientific and technical, natural and social factors. Such an approach is a subject of our further scientific studies and it encourages the next stage of searches - research into the international aspects of institutional provisions for controlling international e-commerce activities.

Diabetic retinopathy remains one of the greatest challenges for healthcare system worldwide despite the fact that the incidence of visual acuity impairment in diabetic population has decreased due to examination quality improvement and dynamic observation of patients. Visual acuity impairment in diabetic patients is often related to diabetic macular edema. Until recently, laser photocoagulation of the retina was regarded as gold standard for diabetic macular edema treatment. Laser photocoagulation of the retina provides visual acuity stabilization rather than improvement. Since early 2000s, pharmacological approach to this severe disease has been established. As vascular endothelial growth factor (VEGF) is one of the crucial factors involved in the pathogenesis of diabetic retinal disorders, VEGF inhibitors are now recognized as a treatment of choice for diabetic macular edema. This article considers results of different clinical trials investigating anti-VEGF therapy efficacy in DME treatment.

Objective: to evaluate the clinical efficiency of eyelid cryotherapy with an autonomous titanium nicke lide cryoapplicator in patients with ocular rosacea regarding the dynamics of pro- and anti-inflammatory cytokines contents at local levels.

Materials and methods. 65 patients with ocular rosacea were observed. Depending on the therapy received, the patients were divided into two groups: in the main group, eyelid cryotherapy was applied for 2 weeks with an autonomous cryoapplicator made of porous-permeable titanium nickelide, and in the reference group, the patients received a traditional treatment for a month. The contents of cytokines (IL-1, IL-8, IFN-, IL-2, IL-10) in lachrymal fluid was evaluated by ELISA on Days 3, 7 and 30 after treatment.

Results. The opposite nature of cytokine balance changes and the ratio of its pro- and anti-inflammatory link during the follow-up period were revealed. A reliable dynamic increase of examined IFN- and IL2 content in the lacrimal fluid after cryostimulation can evidence for an adequate activation of cellular immunity link, as well as for enhancement of regeneration mechanisms.

Conclusion. The analysis of obtained data evidences for a high efficiency of clinical and immunological effect of lid cryotherapy using titanium nickelide cryoprobe for ocular rosacea treatment.

Background. At the present time, the problem of choice of eye drops to achieve adequate mydriasis with minimal side effects for retinopathy of prematurity screening remains an urgent challenge.

Purpose. To estimate the clinical efficacy of combination mydriatic eye drops Fenicamide in infants born at different gestation terms.

Materials and methods. Under observation, there were 75 newborns (150 eyes) and babies aged from 1 day to 3 months (average, 38.2 32.2 days). Patients were distributed into 3 groups depending on gestational age: group 1 consisted of 25 full-term infants; group 2 of 25 premature babies, and group 3 of 25 extremely preterm infants. To achieve mydriasis, 1 drop of combination eye drops (5% phenylephrine and 0.8% tropicamide) was instilled. Dynamics of pupil diameter change in each group of patients was registered within 4 hours, and side effects were recorded within 24 hours. The quality of fundus visualization was estimated using a pediatric retinal camera RetCam 3.

Results. Maximal pupil dilation (average, 6.5 0.5 mm) was reached to 60 14 min after instillation on average; pupil remained dilated within 1 hour, its diameter became normal in 4 hours. Mydriasis varied from 5.9 mm in extremely premature infants to 7 mm in the full-term newborns (p 0.05), and allowed a full and high quality examination of the fundus in all patients, including the visualization of peripheral zones of the retina for retinopathy of prematurity screening. It was established that drug side effects were absent in 76% (57) of infants, they were present in 24% (18) of infants, mostly as local reaction.

Conclusion. Fenicamide eye drops are an effective mydriatic medication, with a convenient instillation regimen, have minimal side effects, and can be recommended for retinopathy of prematurity screening and monitoring.
