On the neo-Vedanta as reconceptualised by Vivekananda in his Complete Works: A cognitive linguistic analysis in light of Conceptual Metaphor Theory
Authors: Naicker Suren
Published: February 2019

This article investigates the use of metaphorical language in The Complete Works of Swami Vivekananda (henceforth CW). Vivekananda is one of the most important modern-day Hindu scholars because his interpretation of ancient Hindu scriptural lore has been very influential. Vivekananda’s influence was part of the motivation for choosing his CW as the empirical domain for the current study. AntConc software was used to mine Vivekananda’s CW for water-related terms, which seemed to have a predilection for metaphoricity. Which terms to search for specifically was determined after a manual reading of a sample from the CW. The data were then tagged using a convention inspired by the well-known Metaphor Identification Procedure – Vrije University (MIPVU). Then, a representative sample of the data was chosen, and the metaphors were mapped and analysed thematically. Five of these are referred to in this article, but special emphasis is placed on the theme of the Vedanta philosophy as the basis for neo-Hinduism, which has become synonymous with contemporary Hinduism, with Yoga as the practical wing, and Vedanta as the ideological basis for the practice; this aspect is expounded upon in more detail. The study’s main aim was therefore to investigate whether Hindu religious discourse uses metaphors to explain abstract religious concepts in a specific way, and indeed one of the main findings was the pervasiveness of water as a source domain. Hence, the key finding in this article is that neo-Hindu thought, as reconceptualised by Vivekananda, relies heavily on the water frame (as is convention in the field of Cognitive Semantics, conceptual domains are written in upper case, including hypothetical frames and conceptual metaphors), which is not as pervasive in other religio-philosophical traditions.

Существенно непертурбативные эффекты поляризации вакуума в двумерной cистеме Дирака-Кулона при $Z>Z_\mathrm{cr}$. Вакуумная плотность заряда
Authors: Sveshnikov Konstantin Alekseevich , Voronina Yuliya Sergeevna , Davydov Andrei Semenovich , Grashin Petr Anatol'evich
Published: February 2019

Для планарной системы Дирака-Кулона со сверхкритическим протяженным аксиально-симметричным кулоновским источником с зарядом $Z>Z_\mathrm{cr,1}$ и радиусом $R_0$ рассмотрены существенно непертурбативные эффекты поляризации вакуума. На основе специальной комбинации аналитических методов, компьютерной алгебры и численных расчетов, использованной в предыдущих работах авторов для изучения аналогичных эффектов в одномерном "атоме водорода", исследованы поведение вакуумной плотности $\rho_{{\textrm{VP}}}(\vec r )$ и полного индуцированного заряда, а также вакуумная энергия поляризации $\mathcal{E}_{_\textrm{VP}}$. Основное внимание уделяется расходимостям теории и соответствующей перенормировке, сходимости парциальных рядов для $\rho_{\textrm{VP}}(\vec r )$ и $\mathcal{E}_{\textrm{VP}}$, целочисленности полного индуцированного заряда и поведению вакуумной энергии в закритической области. В частности, показано, что перенормировка через фермионную петлю с двумя внешними линиями оказывается универсальным приемом, который устраняет расходимость теории как в чисто пертурбативном, так и в существенно непертурбативном режимах как для $\rho_{\textrm{VP}}$, так и для $\mathcal{E}_{\textrm{VP}}$. Наиболее значимый результат состоит в том, что в такой системе при $Z \gg Z_\mathrm{cr,1}$ вакуумная энергия становится быстро убывающей функцией заряда источника $Z$, достигающей больших отрицательных значений, поведение которой оценивается снизу (по модулю) как $\sim-|\eta_\mathrm{eff}Z^3| /R_0$. Исследована также зависимость эффектов поляризации от обрезания кулоновской асимптотики внешнего поля. Показано, что экранировка асимптотики существенно изменяет структуру и свойства первых парциальных каналов с $m_j=\pm 1/2,\pm 3/2$. Подробно рассматриваются техника непертурбативного вычисления и поведение индуцированной плотности и интегрального наведенного заряда $Q_{\textrm{VP}}$ в закритической области.
О временной эволюции квадратичных квантовых систем: операторы эволюции, пропагаторы, инварианты
Authors: Nagiyev Shakir Mamed , Ahmadov Azer Inshala ogly
Published: February 2019

Метод оператора эволюции применяется к описанию зависящих от времени квадратичных квантовых систем в рамках нерелятивистской квантовой механики. Для простоты рассматриваются свободная частица с переменной массой $M(t)$, частица с переменной массой $M(t)$ в переменном однородном поле и гармонический осциллятор с переменными массой $M(t)$ и частотой $\omega(t)$, на который действует переменная сила $F(t)$. Чтобы построить в явном распутанном виде операторы эволюции для этих систем, с помощью простой техники находится общее решение определенного класса дифференциальных и конечно-разностных нестационарных уравнений движения типа Шредингера, а также операторные тождества типа Бейкера-Кэмпбелла-Хаусдорфа. При известных операторах эволюции нетрудно найти в самом общем виде пропагаторы, инварианты любого порядка, волновые функции и установить унитарную связь между системами. Из полученных общих результатов как частные случаи следуют известные в литературе результаты.
Квантово-механическая эквивалентность метрик центрально-симметричного гравитационного поля
Authors: Gorbatenko Mikhail Vladimirovich , Neznamov Vasiliy Petrovich
Published: February 2019

Проведен анализ квантово-механической эквивалентности метрик центрально-симметричного незаряженного гравитационного поля. Рассмотрены статические метрики Шварцшильда в сферических и изотропных координатах, стационарные метрики Эддингтона-Финкельштейна и Пенлеви-Гуллстранда, нестационарные метрики Леметра-Финкельштейна и Крускала-Шекереса. При использовании вещественных радиальных функций уравнения Дирака и уравнения второго порядка в поле Шварцшильда область определения волновых функций ограничивается значениями $r>r_0$, где $r_0$ - радиус горизонта событий. Соответствующее ограничение существует также в других координатах для всех рассмотренных метрик. Для рассмотренных метрик уравнения второго порядка допускают существование вырожденных стационарных связанных состояний фермионов с нулевой энергией. В результате доказано, что физически значимые результаты по квантово-механическому описанию взаимодействия частиц с гравитационным полем не зависят от выбора используемого в исследовании решения для центрально-симметричного статического гравитационного поля.

Fluorine chemistry at extreme conditions: Possible synthesis of $HgF_4$
Authors: Pravica Michael G. , Schyck Sarah , Harris Blake , Cifligu Petrika , Kim Eunja , Billinghurst Brant
Published: February 2019

By irradiating a pressurized mixture of a fluorine-bearing compound ($XeF_2$) and $HgF_2$ with synchrotron hard x-rays (>7 keV) inside a diamond anvil cell, we have observed dramatic changes in the far-infrared spectrum within the 30-35 GPa pressure range which suggest that we may have formed $HgF_4$ in the following way: $XeF_2 \xrightarrow{hv} Xe + F_2$ (photochemically) and $HgF_2 + F_2 \rightarrow HgF_4$ (30 GPa < P < 35 GPa). This lends credence to recent theoretical calculations by Botana et al. that suggest that Hg may behave as a transition metal at high pressure in an environment with an excess of molecular fluorine. The spectral changes were observed to be reversible during pressure cycling above and below the above mentioned pressure range until a certain point when we suspect that molecular fluorine diffused out of the sample at lower pressure. Upon pressure release, $HgF_2$ and trace $XeF_2$ were observed to be remaining in the sample chamber suggesting that much of the $Xe$ and $F_2$ diffused and leaked out from the sample chamber.

Hepatic glycogen storage diseases: pathogenesis, clinical symptoms and therapeutic management
Authors: Szymańska Edyta , Jóźwiak-Dzięcielewska Dominika A. , Gronek Joanna , Niewczas Marta , Czarny Wojciech , Rokicki Dariusz , Gronek Piotr
Published: February 2019

Glycogen storage diseases (GSDs) are genetically determined metabolic diseases that cause disorders of glycogen metabolism in the body. Due to the enzymatic defect at some stage of glycogenolysis/glycogenesis, excess glycogen or its pathologic forms are stored in the body tissues. The first symptoms of the disease usually appear during the first months of life and are thus the domain of pediatricians. Due to the fairly wide access of the authors to unpublished materials and research, as well as direct contact with the GSD patients, the article addresses the problem of actual diagnostic procedures for patients with the suspected diseases. Knowledge and awareness of the problem among physicians seem insufficient, and research on the diagnosis and treatment of GSD is still ongoing, resulting in a heterogeneous GSD typology and a changing way of its diagnosis and treatment.
Return to the origin: what creates a procrastination identity?
Authors: Tibbett Thomas P. , Ferrari Joseph R.
Published: February 2019

Background

Procrastination affects over 20% of adult men and women, with current international data indicating a global preference to sys-tematically delay the start or completion of intended tasks. Procrastination is a common, sub-optimal decision-making strategy that emphasises short-term benefits at the expense of later performance. Some individuals develop a pattern of procrastination which proves difficult to break; worse, they may begin to identify as a procrastinator, setting themselves up for failure.

Participants and procedure

The current investigation examined what develops a procrastinator identity. Previous research indicated that chronic procrastina-tion is a learned tendency beginning in one’s early development from parental control approaches.
We extended that line of research using a cross-cultural sample (n = 2124), self-reported procrastination (behavioural or deci-sional), and retrospective regret scores in 12 domains. We used logistic regression to predict the likelihood of explicitly identify-ing as a procrastinator.

Results

Across three randomised partitions, results indicated that indecision and regrets about education, career, and finances most in-creased the likelihood of identifying as a procrastinator.

Conclusions

These findings support that regrets largely influenced by earning-potential best predict procrastination identity. The current re-sults are consistent with other studies assessing the causes and consequences of chronic procrastination regardless of country or ethnic background. Future research is needed.
“I can’t decide, and it upsets me”: assessing self-critical cognition, indecision, and hope among young adults
Authors: McGarity-Palmer Rebecca , Excell ShayLin , Ferrari Joseph R.
Published: February 2019

Background

Decisional procrastination, or indecision, is the maladaptive postponing of decision-making when faced with conflicts or choic-es. In the present exploratory study, we examined two factors of a psychological model toward understanding the underpinnings of indecision, namely: self-critical cognition as a predisposition to indecision and decreased hope as a post-decision behavior of indecision. Self-critical cognition is the tendency for self-related thoughts to be critical and defeating. It is hypothesized to pre-dict indecision as self-critical individuals are likely to also doubt their competence at tasks such as decision-making and may, in turn, delay. Decreased hope is hypothesized to be an outcome of indecision as the latter is related to anxiety, worry, and life regret.

Participants and procedure

Participants were 327 undergraduate students from a large Midwestern university (242 women, 82 men; Mage = 20.31 years old). They completed the self-report measures in an online survey and received class credit for participation.

Results

Using a bootstrap analysis of the indirect effect, the results showed that indecision mediates the relationship between self-critical cognition and decreased hope among emerging adults.

Conclusions

Implications for future research and potential interventions to alter the pattern of indecision and to increase hope are discussed. This study moves forward the literature of indecision by examining a new predictor and outcome of indecision.
A pictorial essay of the most atypical variants of the vermiform appendix position in computed tomography with their possible
clinical implications
Authors: Zacharzewska-Gondek Anna , Szczurowska Agata , Guziński Maciej , Sąsiadek Marek , Bladowska Joanna
Published: February 2019

Purpose

The tip of the appendix may be located in various areas of the abdominal cavity due to its variable length and/or the changeable position of the caecum. Although in the case of an atypical position the tip is usually located behind the caecum, there are possible locations that occur very rarely. Therefore, in the case of appendicitis the symptoms may lead to the wrong diagnosis. The aim of this study is to present the most atypical locations of the tip of the appendix found on CT (computed tomography) scans and thus help to avoid misdiagnoses.

Imaging findings

The most unusual locations of the tip of the appendix found in healthy subjects included: left inferior quadrant, along the lower edge of the liver near the gallbladder and the right kidney, the tip touching the duodenum, the rectum or appendages, and a long appendix located in the scrotum as the content of a hernia. In these positions, appendicitis may mimic acute diverticulitis, cholecystitis, duodenal ulcer, duodenitis, enteritis, or adnexal or testis pathologies.

Conclusions

It is important to be aware of atypical locations of the appendix because appendicitis in an unusual area may mimic other acute abdominal diseases and delay the proper treatment.
Application of probit method for the elastographic evaluation of venous obliterating material after sclerotherapy procedure
Authors: Paluch Łukasz , Nitek Żaneta , Sklinda Katarzyna , Noszczyk Bartłomiej , Walecki Jerzy
Published: February 2019

Purpose

Status after sclerotherapy constitutes a good clinical model for venous thrombosis with known age. The aim of this study was to compare elastographic parameters of material obliterating the great saphenous vein at 7-21 days after polidocanol sclerotherapy.

Material and methods

The study included 60 patients subjected to sclerotherapy due to venous insufficiency (45 women and 15 men, mean age 51.2 ± 14.7 years, range 27-77 years). Elastographic parameters of obliterating material: total area of vessel cross-section (mm2), relative areas (%) covered by tissues with highest, intermediate, and lowest elasticity, were determined 7 ± 1, 14 ± 2, and 21 ± 2 days post-sclerotherapy, respectively. Mean time to partial and complete organisation of the obliterating material was estimated during probit regression analysis.

Results

The relative area of vessel cross-section covered by tissues with the lowest elasticity underwent a statistically significant enlargement, either between the first and the second (Z = 6.725, p < 0.001) or between the second and the third control visit (Z = 6.717, p < 0.001). This corresponded to a change in the structure of the obliterating material from elastic during the first visit (in all patients) to mixed (fibro-elastic) or fibrous during the third visit (71.7% and 28.3% of patients, respectively). Mean time after which the obliterating material reached mixed and fibrous structure on elastographic images was estimated at 14.3 days and > 21 days, respectively.

Conclusions

Ultrasound elastography may accurately reflect the age of venous thrombosis in polidocanol sclerotherapy model. Mixed, fibro-elastic structure of a 14-day-old obliterating material visualised by elastography probably corresponds with chronic thrombus.
Radiological staging in neuroblastoma: computed tomography or magnetic resonance imaging?
Authors: Sarioglu Fatma C. , Salman Muhammet , Guleryuz Handan , Ozer Erdener , Cecen Emre , Ince Dilek , Olgun Nur
Published: February 2019

Purpose

To compare the effectiveness of computed tomography (CT) and magnetic resonance imaging (MRI) in the staging of neuroblastomas according to the International Neuroblastoma Risk Group Staging System (INRGSS).

Material and methods

In this single-centre retrospective study we identified a total of 20 patients under the age of
18 years, who were admitted to our hospital with neuroblastoma between January 2005 and May 2018, and who had both CT and MRI examination. The INRGSS stages of tumours were evaluated by CT scan and MRI. Then, stages of tumours were described according to the INRGSS for CT and MRI, separately. The Spearman rank correlation test was used for statistical analysis. The p-value < 0.05 was considered as statistically significant.

Results

The median age was 11 months, and the age range was one month to nine years. In our results; both MRI and CT were significant in the determination of radiological staging of NBL, p < 0.001 and p = 0.002, respectively. MRI was superior to CT in radiological staging. MRI was also superior for the detection of intraspinal extension, involvement of multiple body compartments, metastatic disease, and bone marrow infiltration. CT was more useful to consider the relationship between tumours and vascular structures.

Conclusions

MRI and CT have high diagnostic accuracy rates in the staging of pre-treatment neuroblastomas. MRI is important in pre-treatment evaluation of neuroblastomas because of the higher detection of metastases as well as the lack of ionising radiation.
A deceptive case of emphysematous cholecystitis complicated
with retroperitoneal gangrene and emphysematous pancreatitis: clinical and computed tomography features
Authors: Deręgowska-Cylke Małgorzata , Palczewski Piotr , Pacholczyk Marek , Jonas Maurycy , Cylke Radosław , Kosieradzki Maciej , Gołębiowski Marek
Published: February 2019

Purpose

Emphysematous cholecystitis (EC) is an uncommon, severe variant of acute cholecystitis caused by gas- forming bacteria – most often Clostridium perfringens and Escherichia coli. We present a deceptive case of EC associated with retroperitoneal gas gangrene and emphysematous pancreatitis.

Case report

An 86-year-old, overweight woman was admitted to the emergency department with non-specific abdominal symptoms. Admission laboratory tests showed elevated diastase levels indicating acute pancreatitis. Computed tomography (CT) demonstrated a substantial amount of gas in the retroperitoneum and peritoneal cavity, which raised a suspicion of duodenal perforation. Primary diagnosis was not confirmed during emergency laparotomy, which revealed a gangrenous gallbladder adjacent to the duodenum and surrounded by purulent fluid. The final diagnosis established after laparotomy and rereading of CT scans was that of emphysematous cholecystitis associated with gangrenous pancreatitis and retroperitoneal gangrene. After surgery, the patient was transferred to the intensive care unit in septic shock. Shortly after, the second laparotomy was undertaken on suspicion of internal bleeding. During surgery, the patient experienced cardiac arrest and died despite immediate resuscitation.

Conclusions

Emphysematous cholecystitis may be associated with a spread of infection both to the peritoneal cavity and retroperitoneum and result in a substantial amount of gas in those anatomic compartments. The knowledge of this rare complication may be helpful in establishing a correct diagnosis.
Trends in N2O and SF6 mole fraction in archived air samples from Cape Meares, Oregon (USA) 1978–1996
Authors: Rolfe Terry C. , Rice Andrew L.
Published: February 2019

Abstract. Quantifying historical trends in atmospheric greenhouse gases (GHG) is important to understanding changes in their budgets and for climate modeling which simulates historic and projects future climate. Archived samples analyzed using updated measurement techniques and calibration scales can reduce uncertainties in historic records of GHG mole fractions and their trends in time. Here, we present historical measurements of two important GHG, nitrous oxide (N2O) and sulfur hexafluoride (SF6), collected at the midlatitude northern hemisphere station Cape Meares, Oregon (USA, 45.5° N, 124° W) between 1978 and 1996 in archived air samples from the Oregon Health and Science University–Portland State University (OHSU–PSU) Air Archive. N2O is the third most important anthropogenically forced GHG behind carbon dioxide (CO2) and methane (CH4). SF6 has a low abundance in the atmosphere, but is one of the most powerful GHG known. Measurements of atmospheric N2O made during this period are available for select locations but prior to mid-1990 have larger uncertainties than more recent periods due to advancements made in gas chromatography (GC) methods. Few atmospheric SF6 measurements pre-1990 exist, particularly in the northern hemisphere. The GC system used to measure N2O and SF6 concentrations in this work is designed to be fully automated, capable of running up to 15 samples per batch. Measurement precision (1σ) of N2O and SF6 is 0.16 % and 1.1 % respectively. Samples were corrected for detector response non-linearity when measured against our reference standard, determined to be 0.14 ppb ppb−1 in N2O and 0.03 ppt ppt−1 in SF6. The concentration of N2O in archived samples is found to be 301.5 ± 0.3 ppb in 1980 and rises to 313.5 ± 0.3 ppb in 1996. The average growth rate over this period is 0.78 ± 0.03 ppb yr−1 (95 % CI). Seasonal amplitude is statistically robust, with a maximum anomaly of 0.3 ppb near April and a minimum near November of −0.4 ppb. Measurements of N2O match well with previously reported values for Cape Meares and other comparable locations. The concentration of SF6 in analyzed samples is found to be 0.85 ± 0.03 ppt in 1980 and rises to 3.83 ± 0.03 ppt in 1996. The average growth rate over this period is 0.17 ± 0.01 ppt yr−1 (95 % CI). Seasonality is statistically robust and has an annual peak anomaly of 0.04 ppb near January and a minimum anomaly of −0.03 ppt near July. These are unique SF6 results from this site and represent a significant increase in SF6 data available during the 1980s and early 1990s at any location. The concentration and growth rate of SF6 measured compares well to other northern hemisphere measurements over this period. From these N2O and SF6 measurements, overall we conclude that sample integrity is robust in the OHSU–PSU Air Archive.
A broadband cavity-enhanced spectrometer for atmospheric trace gas measurements and Rayleigh scattering cross sections in the cyan region (470–540 nm)

Published: February 2019

Abstract. An incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS)
instrument for quantification of atmospheric trace gases that absorb in the
cyan region of the electromagnetic spectrum (470 to 540 nm), including
NO2 and I2, is described. The instrument uses a
light-emitting diode coupled to a 1 m optical cavity consisting of a pair of
mirrors in stable resonator configuration. Transmitted light is monitored
using a grating spectrometer and charge-coupled device array detector. The
average mirror reflectivity was determined from the N2∕He and
Ar∕He
ratios of scattering coefficients and was ∼99.98 % at its maximum,
yielding an effective optical path length of 6.3 km. Cross sections of
N2, O2, air, Ar, CO2, and CH4 scattering and
of O4 absorption were measured and agree with literature values within
the measurement uncertainty. Trace gas mixing ratios were retrieved using the
spectral fitting software DOASIS (DOAS intelligent system) from 480 to 535 nm. Under laboratory
conditions, the 60 s, 1σ measurement precisions were ±124 and
±44 pptv for NO2 and I2, respectively. The IBBCEAS
instrument sampled ambient air in Ucluelet, BC, Canada, in July 2015. IBBCEAS
retrievals agreed with independent measurements of NO2 by blue
diode laser cavity ring-down spectroscopy (r2=0.975), but ambient
I2 concentrations were below the detection limit.
Evaluating the simulated mean soil carbon transit times by Earth system models using observations

Published: February 2019

Abstract. One known bias in current Earth system models (ESMs) is the underestimation
of global mean soil carbon (C) transit time (τsoil), which quantifies
the age of the C atoms at the time they leave the soil. However, it remains
unclear where such underestimations are located globally. Here, we
constructed a global database of measured τsoil across 187 sites to
evaluate results from 12 ESMs. The observations showed that the
estimated τsoil was dramatically shorter from the soil incubation
studies in the laboratory environment (median = 4 years; interquartile
range = 1 to 25 years) than that derived from field in situ
measurements (31; 5 to 84 years) with shifts in stable isotopic C
(13C) or the stock-over-flux approach. In comparison with the
field observations, the multi-model ensemble simulated a shorter median (19 years) and
a smaller spatial variation (6 to 29 years) of τsoil
across the same site locations. We then found a significant and negative
linear correlation between the in situ measured τsoil and
mean annual air temperature. The underestimations of modeled τsoil
are mainly located in cold and dry biomes, especially tundra and desert.
Furthermore, we showed that one ESM (i.e., CESM) has improved its
τsoil estimate by incorporation of the soil vertical profile. These
findings indicate that the spatial variation of τsoil is a useful
benchmark for ESMs, and we recommend more observations and modeling efforts
on soil C dynamics in regions limited by temperature and moisture.
Wheat bran stabilization and its effect on cookies quality
Authors: Lauková Michaela , Karovičová Jolana , Minarovičová Lucia , Kohajdová Zlatica
Published: February 2019

Wheat bran are widely used as a source of dietary fiber with enhanced health benefits. However, its hight application level in bakery products caused lower quality of these products (eg. reduced volume and increased hardness of product). Different mechanical, physical or chemical methods are used for modification of wheat bran physicochemical properties. Wheat bran obtained from two wheat variety was used to evaluate the effect of bran stabilization process on qualitative properties of baked goods. Stabilization was performed using hot air and microwave heating. Threated and unthreated wheat bran were blended with wheat flour at 5, 10 and 15% substitution level. Influence of bran addition on rheological properties was evaluated using Mixolab 2. Stabilized wheat bran increased water absorption up to 11.7% (hot air stabilization) and 11.9% (microwave stabilization), respectively. Hot air stabilization of wheat bran improved heat resistance of dough proteins during mixing and the stability of hot gel during heating. Stabilization process of wheat bran using both methods also increased the volume and spread ratio values of enriched cookies. Cookies incorporated with hot air treated bran were significantly softer than cookies contained raw bran. Sensory evaluation showed that addition of stabilized bran improved the shape and taste of cookies. Additionally, it was concluded that the most acceptable cookies were obtained at 5% addition level of bran stabilized using microwave heating.
Molecular characterization and genetic diversity in some Egyptian wheat (Triticum aestivum L.) using microsatellite markers
Authors: El-Fiki Ayman , Adly Mohamed
Published: February 2019

Wheat (Triticum aestivum L.) is the most important and strategic cereal crop in Egypt and has many bread wheat varieties. Seventeen Egyptian bread wheat varieties used in this study with a set of sixteen wheat microsatellite markers to examine their utility in detecting DNA polymorphism, estimating genetic diversity and identifying genotypes. A total of 190 alleles were detected at 16 loci using 16 microsatellite primer pairs. The number of allele per locus ranged from 8 to 20, with an average of 11.875. The polymorphic information content (PIC) and marker index (MI) average values were 0.8669, 0.8530 respectively. The (GA) n microsatellites were the highest polymorphic (20 alleles). The Jaccard's Coefficient for genetic similarity was ranged from 0.524 to 0.109 with average of 0.375. A dendrogram was prepared based on similarity matrix using UPGMA algorithm, divided the cultivars into two major clusters. The results proved the microsatellite markers utility in detecting polymorphism due to the discrimination of cultivars and estimating genetic diversity.
Economic Expectations of the Belt and Road Initiative for the South Caucasus, with Emphasis on Georgia
Authors: Gigauri Iza , Damenia Nino
Published: February 2019

Georgia, a post-soviet country, located in the South Caucasus at a crossroads of Europe and Asia, presents Europe’s natural gateway towards Asia. The Belt and Road Initiative, also known as the One Belt One Road, is 21st century Silk Road encompassing transportation and communication systems connecting China to Europe. Since the Initiative is at its beginning stage, it is essential to study its economic influence on the South Caucasus region it traverses, and particularly, upon Georgia. In this respect, to facilitate sustainable growth in the region, advanced technology, industrial and infrastructural modernization is crucial. Under the Initiative, Baku-Tbilisi-Kars railway is completed, which can significantly shorten the time of shipment from China to Europe, and Georgia's Anaklia Deep Sea Port on the Black Sea with a huge capacity of cargo transportation is under construction. The infrastructure investments under the Initiative can encourage economic development and hence, reduce poverty.

Bilingual Match to Biblical Flood
Authors: Du James Xianxing
Published: February 2019

In this testimony, vowel next to two l letters is proposed as a novel affix that represents dissected offering at burnt altar. In turn, biblical etymology of flood is presented to be double hands in offering flock to worship, and the etymology of boat is both male and female in pair. All the words for ships are linguistically related to either Noah’s ark or worship. 牙  tooth is originated from two people in mating to match Noah’s covenant about food and multiplication after the flood. An affix for burning, c+vowel+n, is also verified. For the first time in human history, a large variety of words related to great flood, ark and Noah’s worship are presented to match bible in semantic origin, indicating divine creation of languages.
Playful Lenses: Using Twine to Facilitate Open Social Scholarship through Game-based Inquiry, Research, and Scholarly Communication
Authors: Wilson Rebecca , Saklofske Jon , INKE Research team The
Published: February 2019

In academic contexts, digital games are often studied as texts or are used as pedagogical tools to teach basic concepts in early education situations. Less usefully, their systems and economies are often co-opted and decontextualized in short-sighted attempts to “gamify” various aspects of learning or training. However, given that games are highly controlled, conditional, choice-and-consequence-based, problem-solving environments in which players are expected to interact with simulated settings and elements after agreeing to take on particular roles and subject positions, there are promising potential uses of these experiences in academic contexts that have not been fully considered. Motivated by the imperative to explore alternative modes and methods of scholarly research and communication, and guided by the values of open social scholarship practices, this paper reconsiders games not as things to study, but as instruments to study with. Given that games can function as simulations, models, arguments and creative collaboratories, game-based inquiry can be used as a potential method of post-secondary and post-graduate humanities research and scholarly communication. While these ideas have been explored in a preliminary way in relation to a number of different academic disciplines (Donchin 1995; Boot 2015; Mitgutsch and Weise 2011; Westecott 2011) this paper is meant to catalyse a humanities-calibrated consideration of the pragmatics and potentials of game-based research, games as instances of critical making and scholarly communication, and more complex forms of game-based learning than those currently practiced. A number of examples that make use of the open source Twine platform will be featured.
Foundations for On-Campus Open Social Scholarship Activities
Authors: El Khatib Randa , Arbuckle Alyssa , Siemens Ray
Published: February 2019

Social knowledge creation, citizen scholarship, interdisciplinary collaborations, and university-community partnerships have become more common and more visible in contemporary academia. The Electronic Textual Cultures Lab (ETCL) currently focuses on how to engage with such transformations in knowledge creation. In this paper we survey the intellectual foundation of social knowledge creation and major initiatives undertaken to pursue and enact this research in the ETCL. “Social Knowledge Creation: Three Annotated Bibliographies” (Arbuckle, Belojevic, Hiebert, Siemens, et al. 2014), and an updated iteration, “An Annotated Bibliography on Social Knowledge Creation,” (Arbuckle, El Hajj, El Khatib, Seatter, Siemens, et al, 2017), explore how academics collaborate to create knowledge, and how social knowledge creation can bridge the real or perceived gap between the academy and the public. This knowledgebase lays the foundation for the “Open Social Scholarship Annotated Bibliography” (El Hajj, El Khatib, Leibel, Seatter, et al. 2019), which draws on research that adopts and propagates social knowledge creation ideals and explores trends such as accessible research development and dissemination. Using these annotated bibliographies as a theoretical foundation for action, the ETCL began test-driving open social scholarship initiatives with the launch of the Open Knowledge Practicum (OKP). The OKP invites members of the community and the university to pursue their own research in the ETCL. Research output is published in open, public venues. Overall, we aim to acknowledge the expanding, social nature of knowledge production, and to detail how the ETCL utilizes in-person interaction and the digital medium to facilitate open social scholarship.
Spreadable Jams: Implementing Social Scholarship through Remodeled Game Jam Paradigms
Authors: Saklofske Jon
Published: February 2019

Game design communities often come together during ‘Game Jams,’ open social events in which game makers creatively respond to a design provocation by generating numerous prototypes over a short period of time. Such prototypes are often discussed between participants at the end of the event, then shared with a larger public audience. This fruitful process, which encourages collaborative sharing rather than competition between participants, differs in purpose, structure and outcome from many existing models of academic scholarship and scholarly communication. Inspired by the potential of such events, this paper argues that the game jam paradigm, and more generally, ‘spaces apart,’ can be effectively adopted, adapted, and repurposed to facilitate a broader social generation and dissemination of research creation prototypes, modelling an alternative kind of scholarly making in the humanities that runs parallel to, and is as equally valued and valid as, existing publication models.
Developing an Open Social Scholarship Collaboration: Lessons from INKE
Authors: Siemens Lynne , INKE Research Group The
Published: February 2019

Many academic teams and granting agencies undergo a process of reflection at the completion of research projects to understand lessons learned and develop best practice guidelines. Generally completed at the project’s end, these reviews focus on the actual research work accomplished with little discussion of the work relationships and process involved. As a result, some hard-earned lessons are forgotten or minimized through the passage of time. Additional learning about the nature of collaboration may be gained if this type of reflection occurs during the project’s life. Building on earlier examinations of INKE, this paper contributes to that discussion with an exploration of seventh and final year of a large-scale research project.Implementing New Knowledge Environment (INKE) serves as a case study for this research. Members of the administrative team, researchers, postdoctoral fellows, graduate research assistants, and others are asked about their experiences collaborating within INKE on an annual basis in order to understand the nature of collaboration and ways that it may change over the life of a long-term grant. Interviewees continue to outline benefits for collaboration within INKE while admitting that there continue to be challenges. They also outline several lessons learned which will be applied to the next project.

An Extended Stochastic Goal Mixed Integer Programming for Optimal Portfolio Selection in the Amman Stock Exchange
Authors: AlHalaseh Rula Hani Salman , Islam Aminul , Bakar Rosni
Published: February 2019

This paper optimally solves the portfolio selection problem that consists of multi assets in a continuous time period to achieve the optimal trade-off between multi-objectives. In this paper, the Stochastic Goal Mixed Integer programming of Stoyan (2009) is extended. The empirical contributions of this research presented on extending the SGMIP model by adding information as a new factor that selects the portfolio elements. The information element used as a portfolio managing characteristics to see whether it is applicable for different problems. The data was collected on a daily basis for all the parameters of the individual stock. Brownian motion formula was used to predict the stock price in the future time period. SP framework used to capture numerous sources of uncertainty and to formulate the portfolio problem. The main challenge of this model is that it contains additional real-world objective and multi types of financial assets, which form a Mixed Integer Programming (MIP). This large-scale problem solved using Optimising Programming Language (OPL) and decomposition algorithm to improve the memory allocation and CPU time. A fascinating result was obtained from the portfolio algorithm design. The ESGMIP portfolio outperforms the Index portfolio return. Under uncertain environment, the availability of information rationalized the diversity when the dynamic portfolio invested in one financial instrument (stocks), and tend to be diversifiable when invested in more than one financial instrument (stock and bond). This work presents a novel extended SGMIP model to reach an optimal solution.

Business like Solutions suggested for Two World Problems in a Developing Nation (Analytical Study)
Authors: Alkayed Waiel
Published: February 2019

With overpopulation, surrounding wars, incoming refugees, insufficient natural resources and dependent on aid for survival, Jordan possesses tourism and an educated population as assets to strategies. Based on the ideal of social justice, this developing nation can utilize the concept of corporate social responsibility to encourage businesses, provide land and employ its educational assets for their benefit. It can thus commodity its educational facilities; pair with neighboring lesser educated nations for educational provision, and exercise Ministerial powers in government administration to set up “brain-drain” scholarships, joint international tertiary universities with subsequent employment and regional development. Half the population (women) could be empowered by allowing and providing employment by protected internships, if social mores of patriarchy could be loosened. This would begin female emancipation, increase social justice, profits and consumption, consequently improving sustainable economic benefits.
