Relative social inequality in the world: Rigidity against the economic growth, 1992–2016
Authors: Grigoryev Leonid M. , Pavlyushina Victoria A.
Published: April 2019

The study of economic growth and social inequality goes back to the works of S. Kuznets, A. Atkinson, P. Krugman, J. Stiglitz, T. Piketti, and B. Milanovic. Statistical analysis of social inequalities for a large set of countries, divided into seven clusters, was conducted for the period 2000–2016. The share of incomes of the 10th decile was used as a measure of inequality. The hypothesis of the positive impact of economic growth on the reduction of social inequality was tested. Stylized facts on an array of 106 countries for the period under review indicate a high degree of stability of the level of inequality in most groups, especially in the most developed countries, and in particular in the Anglo-Saxon ones. The distribution of key socioeconomic and even political indicators for clusters shows their strong relationship with the structure of cluster inequality. This makes it possible to significantly deepen the analysis, in particular the one concerning the stages of world development.

DETERMINATION OF THE PERIOD OF MARKOV CHAIN’S TRANSITION MATRIX FOR MILITARY MANPOWER PLANNING IN INDONESIAN NAVY
Authors: Wahyuli Agus
Published: April 2019

 

Abstract

 

 

Human resources are very important organizational assets thus it is only natural that every organization gives more attention to human resource management, including the Indonesian Navy (TNI AL). The approach to human resource planning in military organizations focuses on two aspects, including long term planning with strategic objectives and short term planning with operational objectives. This long term planning is oriented towards the continuation of the procurement, availability, and balance of the number of personnel (human resources) in each rank in the future. An analysis to find out and plan the condition of Navy personnel in the future is needed, which is called the analysis of the Markov chain. There are at least three stages of the Markov chain process, including determining the state, the transition matrix, and the initial vector value. The transition matrix describes changes from one state to another state in the next period of time. The transition matrix formed is the basis of the subsequent analysis, including the calculation of the number of personnel per rank in the future. Determining the length of the matrix period is done by comparing several transition matrices with various moving average orders. The result obtained suggests that the best transition matrix is the one with moving average orders six, including the transition matrix with the smallest value of Mean Square Error (MSE).

Published: April 2019

The main objective of this study was to analyze the essential oil composition of cultivated lavandin (Lavandula x intermedia Emeric ex Loisel., Lamiaceae) from Republic of Macedonia and to evaluate the influence of the drying time of plant material and the distillation duration on the oil composition. Four different essential oils were obtained by hydrodistillation in a Clevenger type apparatus from freshly harvested and air dried flowers of lavandin and varying in distillation time (30 min and 2 h). Fifty-six compounds were identified by GC/ FID/MS representing 96.57% to 98.23% of the total oil. Prevailing constituents in all tested oils were linalool, borneol and terpinene-4-ol, present in amounts from 35.23 to 42.24%, 12.28 to 16.68% and 4.44 to 5.62%, respectively. The content of 1,8-cineole varied from 3.99% to 8.42% while that of camphor was between 5.96% and 7.04%. Linalyl acetate was present in amounts from 1.26% to 3.21%. Unexpectedly, the duration of distillation insignificantly influenced the essential oil composition. Few differences, mainly in the content of borneol (13.71% and 16.68% in the oil from fresh and dried flowers, respectively) were recorded in the essential oils obtained by 30 minutes distillation, while the content of the other constituents was almost unchanged. However, the isolated essential oils of lavandin did not comply
with the international standards requirements for the lavandin essential oil composition.

From a historical point of view, one can notice that the role of the pharmacists employed in community and hospital pharmacies became more complex. Today, they do not only supply, store, prepare and dispense medicines with ensured quality, but they also provide professional services based on the concept of pharmaceutical care and good pharmacy practice. In this paper, detailed review on the current legislative regulating the status and practice of the community and hospital pharmacies in some EU-member countries and in Macedonia is given. The implementation of the concept of pharmaceutical care and good pharmacy practice in selected EU member-countries, Great Britain, Germany and Slovenia, and in Croatia as a future EU member as well as in Macedonia is also discussed. In addition, set of recommendations for establishing the good pharmacy practice standards is prepared and presented. At the end, an attempt is made to establish a basis for development a modern Law on Pharmacy Practice in the Republic of Macedonia.

Chemical composition and antimicrobial activity of essential oils isolated from leaves of three different samples of wild growing Juniperus communis L. (Cupressaceae) from R. Macedonia was investigated. Essential oil yield ranged from 7.3 to 9.0 ml/kg. Performing GC/ FID/MS analysis, ninety components were identified, representing 86.07-93.31% of the oil. The major components of the leaves essential oil (LEO) were α-pinene (21.37-28.68%) and sabinene (2.29-16.27%), followed by limonene, terpinen-4-ol, β-elemene, trans-(E)-caryophyllene, germacrene D and δ-cadinene. Antimicrobial screening of the LEO was made by disc diffusion and broth dilution method against 16 bacterial isolates of Gram positive and Gram negative bacteria and one strain of Candida albicans. Two bacteria, Staphylococcus aureus and Streptococcus pyogenes were sensitive to antimicrobial activity of LEO (MIC = 125 µl/ml). Additionally, LEO showed moderate
antimicrobial activity against Streptococcus agalactiae, Haemophilus influnzae, Corynebacterium spp. and Campylobacter jejuni (MIC > 500 µl/ml). Candida albicans, Staphylococcus epidermidis, Acinetobacter spp., Salmonella enteritidis, Shigella flexneri, Klebsiella pneumonia, Pseudomonas aeruginosa and Proteus mirabilis were completely resistant to the antimicrobial effects of this.

Authors: Manuilskaya Kseniya , Vyrskaya Marina
Published: April 2019

The article presents the cognitive capabilities of online surveys for studying narrow, hard-to-reach target groups. The key issue of a survey conducted with specific audiences is respondents' search and involvement. The authors measured the response rate of labor migrants and people with disabilities according to the findings of the methodical analysis of two online surveys. The article proposes an algorithm of response rate measurement by internal and external parameters. Primary focus is on comparing the effect of using targeted advertising on Facebook and Yandex; the perception of advertising banner analysis in the context of survey's successful finishing; the calculation of response rate and several other indicators. The results of the methodical research indicate the most effective ways of audience involvement in online surveys, the importance of the questionnaire design, especially the first question. The main conclusion is that the test method provided with a set of conditions can be used for studying narrow target groups.

Addressing America’s Current and Future Educational Challenges
Authors: Counts John
Published: April 2019

Experience informs us that, after parents and guardians, educators have the greatest level of influence on children of all ages. These are the educators we prepare on our university campuses every semester, year after year, for whom the act of teaching is much more than a monthly paycheck, but is rather a very special calling.

Parents, whose children are taught by the teachers and administrators our universities prepare, typically praise their local schools, teachers, administrators and support personnel. However, when we move beyond these familial educational settings, the general level of criticism directed toward our public schools and schools of education has never been higher.
The Chronicles of The Renaissance Group
Authors: Giovannetti Michael Joseph
Published: April 2019

The Renaissance, French for “rebirth”; Italian, Rinascimento, from re - “again” and nascere -“to be born”, was a cultural movement that initiated in Florence, Italy, in the Late Middle Ages and later spread to the rest of Europe, encompassing periods from the Fourteenth to the Seventeenth Century.  This time was focused on the improvement of various disciplines, through a revival of ideas from antiquity, by employing new, creative approaches to thinking and doing.  The influence of the Renaissance movement affected art, literature, philosophy, politics, science, religion, politics and other aspects of intellectual inquiry.

 

What does the Renaissance movement of Fourteenth Century Italy have to do with The Renaissance Group (TRG) of 21st century America?  The times and places may be very different, but as we review TRG’s contributions to teacher education from the 1980s to the present, a time during which The Renaissance Group laid a strong foundation to shape this national consortium of colleges, universities and professional organizations, we may discover more similarities between the two entities than imagined.

By leveraging the strengths and commitments of each of the partners, a university, a private nonprofit, and a middle-sized urban school district, collaborated to impact student learning of key concepts in middle-grade mathematics and to change mathematics teaching. The project targeted middle grades mathematics because success in it is the greatest predictor of later school achievement. In well-researched learning modules, students visualize, interact with, and analyze mathematical representations connected to dynamic simulations of real-life phenomena in a curricular learning system comprising dynamic technologies, curriculum replacement units, and professional development. Through planned professional development, teachers have the technological skills, pedagogical skills and mathematical content knowledge required to engage their students in an interaction between the software, the curriculum materials, and the mathematics. Student learning gains and changes in teacher pedagogical, technological, and mathematical content knowledge provide evidence of the project’s continued success after three years. Concomitant institutional changes in each of the partnering organizations attest to the project’s sustainable impact.

Published: April 2019

With the implementation of Common Core State Standards (CCSS), K-12 teachers, counselors, and administrators will be held accountable for meeting the explicitly defined standards of college and career readiness for every high school graduate.  An equivalent and reciprocal challenge is also placed upon universities to prepare future education professionals to successfully meet the expectations for CCSS downstream outcomes.  This will require significant changes to higher education processes to ensure rigorous teacher preparation which includes not only best practices in pedagogy, but also full understanding of the standards set forth by the CCSS.  However, opportunities for developing in pedagogy and CCSS do not commonly exist.  In an attempt to improve pedagogical rigor of new faculty members, the Network for Instructional Support and Enhancement (NISE) Program at the University of Central Missouri was initiated in the fall semester of 2012.  Comprised of an orientation and mentoring process, this study provides an evaluation of the programs strengths, deficiencies and specific suggestions for enhancing the program.  The research is limited because it was conducted at the mid-point of the pilot delivery of the complete program.   Qualitative analysis was conducted on data collected from university senior leaders, NISE Program committee members and new faculty about their perceptions of the program’s delivery and impact.

Published: April 2019

Educational practitioners in the 21st century must respond to the availability of a wide array of data relating to student outcomes and student achievement. To make effective use of this data as well as be able to respond to the growing needs of the field, educational practitioners must be able to apply the knowledge they gain in the graduate preparation programs. In this article, the authors reflect on the role of a signature pedagogy grounded on inquiry-based learning in their leadership development, and how an ongoing emphasis on action research throughout their doctoral program was invaluable in their professional and academic growth. As a result, the authors recommend that action research should strongly supplement traditional, theory-driven graduate pedagogy in education.

Published: April 2019

Background. This study investigated the acute effects of different half–time re–warm ups on vertical jump
height during simulated basketball games.
Methods. Ten college level males (age (mean ± standard deviation (SD)), 22.0 ± 5.0 years; weight, 86.0 ± 5.5 kg;
height, 193 ± 1 cm.) were divided into two teams, who played three simulated basketball games with three different
type half-time re-warm ups: aerobic; aerobic + post-activation potentiation exercises and aerobic + post-activation
potentiation + stabilization exercises. Counter-movement jump was measured before and during the simulated
basketball game at seven time points: before and after warm up, after the 1 st, the 2 nd quarters, after re-warm up and
after the 3 rd and the 4 th quarters. Simulated basketball games were separated at least by 72 hours.
Results. The non-significant decrease in Counter-movement jump height during simulated basketball games
was observed after executing all three different types of half-time re-warm ups. However, Counter-movement jump
significantly (p < .05) decreased during simulated basketball game only in aerobic type half-time re-warm up game.
Conclusion. During simulated basketball game, the least decrease in Counter-movement jump height was
observed after aerobic type re-warm up with post-activation potentiation exercises performed at half-time.
THE MANAGEMENT OF TURF TOE – A SYSTEMATIC REVIEW
Authors: Hainsworth Louis , McKinley John
Published: April 2019

Background. Turf toe is used to describe an injury occurring at the plantar aspect of the metatarsophalangeal-
sesamoid complex of the hallux. Typically seen in athletes, it occurs due to hyperdorsiflexion and axial loading
of the hallux metatarsophalangeal joint with the foot fixed in equinus. The injury causes pain and joint instability,
missed athletic activity and potentially end careers. Turf toe can be managed conservatively or operatively, with
controversy regarding the indications for operative intervention. This study aims to conduct a systematic review to
determine whether and in what circumstances operative intervention is superior to conservative management of turf
toe in adults.
Methods. A systematic review of the literature was performed using PubMed, Embase, Cochrane and
Scopus databases. The search terms used were “turf toe”, “first metatarsophalangeal joint injury”, “conservative”,
“nonoperative”, and “operative”. All articles published in English reporting on the management of turf toe were
reviewed. The primary outcome measure was the time to return to pre-injury activity with the secondary outcome of
the time to symptom resolution.
Results. Seven studies met the inclusion criteria. Three patients were successfully managed conservatively
returning to athletic activity, on average at 12 weeks. Seventeen patients underwent surgical intervention with an
average return to athletic activity at 18 weeks.
Conclusion. Operative intervention was shown to give a successful outcome in patients with grade three turf
toe injuries or those who have failed conservative management. However, there is insufficient evidence to determine
whether operative intervention is superior to conservative management.

Malate synthases found in cells of the halophilic Archaea constitute a third isoform of this important metabolic enzyme, in addition to the well characterized A and G isoforms. They share little sequence similarity with these other two isoforms. Database searches using basic local alignments reveal relationships between isoforms A and G, but do not indicate a significant sequence relationship between members of this third isoform and those of isoform G, and only a distant relationship with members of isoform A. This third isoform, which we propose to call isoform H (Halophilic archaeal), is also significantly smaller in size: ~100 residues shorter than isoform A, and ~300 residues shorter than isoform G. Representatives of both isoform A and G have been structurally characterized, but no three-dimensional structural information exists for isoform H. Here we report the crystallization and preliminary X-ray diffraction from a crystal form of an H-isoform member, the malate synthase from the halophilic archaeon Haloferax volcanii, originally isolated from the mud of the Dead Sea. This crystal form diffracts well, and is amenable to single crystal X-ray analysis.
Longitudinal Light Clock and Zeno’s Paradox
Authors: Fixelle Joshua , Johnson Austin
Published: April 2019

Introductory college text books consider time dilation through the derivation of the transverse light clock. We consider the case of the longitudinal light clock and derive the time dilation formula of special relativity. Our methods yield the same result as derived by the transverse light clock, and help explain the concept of failure of simultaneity.
The E3 Ubiquitin Ligase NARF Promotes Colony Formation in vitro and Exhibits Enhanced Expression Levels in Glioblastoma Multiforme in vivo
Authors: Anderson Tucker , Wright Christopher , Brooks William
Published: April 2019

The ubiquitin ligase NARF is a newly identified protein belonging to a small family of structurally similar E3 proteins. NARF is a negative regulator of the canonical Wnt-β-catenin pathway, targeting TCF/LEF family members for proteolytic degradation through poly-ubiquitination. We examined the role that NARF plays in cell division and found that overexpression of NARF in a colony forming assay increases colony formation in a RING finger-dependent manner. Furthermore, we demonstrate that NARF transcripts are expressed at a higher level in the grade IV brain tumor glioblastoma multiforme as compared with low grade astrocytomas. Our data thus indicate that NARF is a positive regulator of cell growth and may be involved in the tumorigenic process.

Using Ohm’s Law to Calibrate a Picoammeter to 0.4 Pico-ampere Precision
Authors: Hashem Joseph , Liu Tiankuan , Liang Zhihua , Ye Jingbo
Published: April 2019

We present an experimental method based on Ohm’s Law to calibrate the Keithley 6485 picoammeter with the calibration error less than 0.4 pico-ampere (pA), which is specified as the highest sensitivity of this instrument. The maximum calibration difference between the measurement current and the calibration current in the picoammeter’s 2 nano-ampere (nA) range is 0.25 pA. This difference is far less than the highest accuracy, 0.4 pA, specified by the instrument. Measurement errors are estimated and discussed.
Designing and Constructing a Controlled-Flow Apparatus to Study the Effect of Surface Flow Velocity on the Quality of Electropolishing of Niobium
Authors: Wang Tina , Kelley Michael
Published: April 2019

The focus of this project was to design and construct a model controlled-flow apparatus to study electropolishing of one cm2 niobium coupons at surface flow rates typical of cavity processing. A simulation of the apparatus was constructed using CFDesign, a flow and thermal simulation software, to ensure that the selected dimensions may be expected to provide steady-state, laminar flow across the surface of the niobium coupon. Based on these dimensions, a sample system and apparatus was produced to determine the correct reservoir elevation heights for the desired flow rates for fluid viscosities represented in the mixed acid electrolyte. From the CFDesign simulations, it was found that the flow channel supplied laminar flow rates when the center of the niobium coupon was located 40 mm downstream from the inlet stream. The corresponding system, based on the CFDesign simulations, showed that the reservoir elevation heights for flow rates of 0 cm/s to 5 cm/s ranged from 0 to 1.27 cm. The correlation between pressure heads and flow rates has been analyzed and an equation for flow rate was determined using experimental results. The detailed dimensions regarding the flow channel and information regarding the respective pressure heads serve as resources to finding the optimal flow rate for electropolishing the niobium cavities. Although previous research has found a correlation between the quality of electropolishing and internal surface flow rates, research facilities, including Jefferson Lab, did not have the equipment to pursue further analysis. Each nine-cell niobium cavity costs over $50,000, so it is cost prohibitive to use real cavities to conduct early stage research. The prototype built through this research work provides a cost effective alternative. It can be used to validate some of the theoretical results obtained through simulation. In addition, the device allows for easy variable measurements that are either difficult or impractical with an enclosed niobium cavity, as sensors can be embedded into the device in the construction stage. Moreover, the data collected through our experiment furthers superconducting radiofrequency (SRF) technology by allowing Jefferson Lab to design a more effective electropolishing process.
Determination of Cadmium and Lead in Northern Pike from the Missouri River
Authors: Even Jennifer , Ghaffari Shahrokh
Published: April 2019

Lead and cadmium are trace metals which accumulate in the body and are extremely toxic in living organisms. The purpose of this study was to find organ(s) with the greatest concentrations of these elements. In this study liver, gill, intestines, and kidney of five samples of Northern Pikes were analyzed. After the organs were dried and digested using nitric acid the anodic stripping voltammetry method was employed to analyze this samples. This method was used for its low detection limit of 10-9 to 10-10 M. However, no trace of either lead or cadmium was found in all 60 samples analyzed. Lack of detectable amount of both lead and cadmium is attribute to; first, Northern Pikes are not bottom dweller and thus would not be highly exposed to sediments that most commonly contain trace metals, second, the absence of a major industry which typically produces these contaminates in this area.
A New Vectorization Technique for Expression Templates in C++
Authors: Progsch J , Ineichen Y , Adelmann A
Published: April 2019

Vector operations play an important role in high performance computing and are typically provided by highly optimized libraries that implement the Basic Linear Algebra Subprograms (BLAS) interface. In C++ templates and operator overloading allow the implementation of these vector operations as expression templates which construct custom loops at compile time and providing a more abstract interface. Unfortunately existing expression template libraries lack the performance of fast BLAS implementations. This paper presents a new approach - Statically Accelerated Loop Templates (SALT) - to close this performance gap by combining expression templates with an aggressive loop unrolling technique. Benchmarks were conducted using the Intel C++ compiler and GNU Compiler Collection to assess the performance of our library relative to Intel's Math Kernel Library as well as the Eigen template library. The results show that the approach is able to provide optimization comparable to the fastest available BLAS implementations, while retaining the convenience and flexibility of a template library.
A Multi-Objective, Linked-Simulation-Optimization of Henry’s Saltwater Intrusion Problem using HST3D and Box’s Method
Authors: Curtis Emily , Willis Robert
Published: April 2019

A multi-objective linked simulation and optimization (LSO) model for a three dimensional saltwater intrusion problem has been developed. The LSO employs HST3D and Box’s algorithm. The weighting method of multi-objective optimization solves the multi-objective planning problem. The model is capable of determining the optimal pumping rates that minimize the saline concentration at the well sites, as well as, the cost associated with pumping, while satisfying an exogenous water demand. The model is valid for a wide range of applications as explicitly defined by the simulation model. The application of the model was limited to a modified version of Henry’s saltwater intrusion problem. Henry’s problem was modified to include a third spatial dimension and well sites. The multi-objective optimization yielded explicit tradeoff information between the two objectives.
