Applying Intelligent Portfolio Management to the Evaluation of Stalled Construction Projects
Authors: Erzaij Kadhim Raheim , Hatem Wadhah A. , Maula Baydaa Hussain
Published: June 2020

Much research in the construction industry is based on the concept of a unique project; hence, such concepts (or philosophy) present the construction project as a unit of analysis for the entire completion process that is usually delivered independently. Most decision support tools in construction have been designed at the project level rather than for construction institutions that often implement many projects simultaneously. Typically, these projects have common objectives that create dependencies among them. Then, the success of one project depends on other projects and the existing interrelationships among them. Thus, construction institutions still need to deal with their projects from a portfolio perspective,which requires strategic management at a portfolio level. This paper employs resource management techniques to allocate resources to manage construction portfolios. A case study targeted strategic decision making about financing projects that have stalled. The final recommendation of this paper is to use development and planning software to serve and support strategic decisions in institutions with concurrent stalled projects.

Published: June 2020

The purpose of this study was to clarify the silicon-germanium dioxide (SiGeO2) and Aluminum Indium Gallium Arsenide (AlInGaAs) based acoustic optic modulators for upgrading transmission performance characteristics. The transient time response of these modulators is analyzed and discussed in detail. The 3-dB modulation signal bandwidth, diffraction signal efficiency, signal rise time, and signal quality factor with minimum data error rates are also considered. The proposed models with silicon-germanium dioxide and Aluminum Indium Gallium Arsenide acoustic optic modulators were compared to the previous model with silicon acoustic optic modulators. The results confirmed the high-performance efficiency of the proposed models when compared to the previous model, in both the lowest transient time response and the highest acoustic optic modulators speed response.

Authors: El-Hageen Hazem M. , Alatwi Aadel M. , Rashed Ahmed Nabih Zaki
Published: June 2020

This study reports the efficient use of a direct laser modulated response measured with the return-to-zero coding scheme in optical transmission systems. The measured direct laser modulated response has a bit rate of 1.2 Gbps for an optical fiber cable of a transmission length of 10 km. The eye diagram analyzer is used to calculate the maximum quality factor and minimum bit error rate of the proposed model. The maximum quality factor is 531.2, and the minimum bit error rate tends to zero for the same optical fiber channel length compared with that of the previous model. The proposed model provides better results than the previous model. The figures of the proposed model are more stable than those of its previous counterpart. Bit error rate approximately tends to zero in the proposed model.

Published: June 2020

Objectives

To determine the prevalence of Second Hand Smoking (SHS) and assess the factors related to exposure, knowledge and response to SHS among adolescents in rural Puducherry, South India.

Methods

A community based cross-sectional study was conducted among adolescents during March and April 2018. Two out of four villages were selected randomly and all the adolescents were contacted through household visit and questionnaire was administered. Semi structured questionnaire contained three sections: sociodemographic details, environmental assessment and third section contained knowledge about SHS, COTPA and response towards being exposed to SHS, as well as exposure history. Continuous variables like age were summarized as mean (SD). Categorical variables such as awareness, attitude and practise towards SHS were summarized as proportions with 95% confidence interval.

Results

Total number of adolescents interviewed was 789. The mean age of the study participants were 14.1 (2.4) years and majority, 440 (55.8%) were boys and 684 (86.7%) belonged to nuclear family. More than one fourth, 210 (26.6%) belonged to middle class of socio-economic status. Environmental assessment of household showed more than half, 456 (57.8%) were staying in pucca house and majority 642 (81.4%) had adequate cross ventilation. It was found that about 70.1% had adequate knowledge about SHS and its harmful effects. Prevalence of exposure to SHS was 49%. Majority (40.5%) told that they will scold or advice the family member to stop smoking if they are exposed to SHS in the living place. However, almost 80% of adolescents mentioned that they will no’t react if they see someone smoking in a public place.

Conclusions

Current study found that almost half of the adolescents were exposed to SHS. Even though, almost three fourth had adequate knowledge, attitude towards preventing SHS in public place was found to be poor. Hence, adolescents need to be motivated enough to address the problem in the public place through motivational counselling in adolescent clinics by health care workers.

Published: June 2020

Objectives

This study aims to explore the utilization rate and factors influencing the use of HCT services among young females in Ikorodu, Lagos State, Nigeria.

Methods

This study was a descriptive cross-sectional survey of 404 females, aged 15–24 years, residing in Ikorodu, Nigeria. Study tool was a questionnaire. Collected data was analyzed using the SPSS version 16 software.

Results

The mean age (±SD) of the respondents was 19.3 (±2.6) years and 90.1% were single. Only 148 (36.6%) respondents had ever utilized the HCT service, of which only 40.5% of them were adolescents. Amongst those that had ever utilized HCT services (n=148), only 60.1% of them did so within 12 months prior to the study while only 33.8% of them initiated the demand for testing themselves. According to the respondents, the top two barriers to the utilization of HCT services were: fear of discrimination (82.9%); and fear of unavailability of access to treatment (68.0%), while the top two factors that facilitates its use were: the adoption of counseling-before-testing approach in the HCT service centers (85.9%); and peoples' need for HIV status declaration prior to getting a job employment/marriage partner (85.1%).

Conclusions

The study shows that utilization of HCT service remains low among the respondents. There is an urgent need to encourage the utilization of HCT services among young females in Ikorodu, Nigeria.
“I think meningitis is a virus, while septicaemia might be caused by bacteria.” A study of vaccination views, disease awareness and MenACWY and MMR uptake among freshers at a London university
Authors: Jones Sophie , Cortina Borja Mario , Bedford Helen
Published: June 2020

Background

University students are at particular risk of invasive meningococcal disease (IMD). Group W, an aggressive strain, is increasing in prevalence and the high case-fatality rate is concerning. Adolescents have been offered the MenACWY vaccine since 2015. National uptake has been low, leaving students vulnerable to infection.

Objectives

To investigate MenACWY uptake, knowledge of IMD and attitudes towards vaccination among UCL first-year students.

Methods

A mixed methods approach was used, involving a questionnaire (n=144) and follow-up interviews (n=13). Students were asked for demographic details and questions including vaccination status, awareness of the vaccine, other vaccination history and knowledge of IMD, which was assessed through true/false/unsure statements. Interviews explored these issues in more detail as well as their suggestions for making vaccination more accessible for students.

Results

MenACWY uptake was 84%, with more socioeconomically disadvantaged students being less likely to be vaccinated (aOR=0.117, p=0.006). Most students thought vaccines were safe and important. Students with above average knowledge were more likely to be vaccinated (OR=3.057, p=0.019). Vaccination views were positive and knowledge level was moderate to high. Reasons for non-vaccination included illness, laziness, forgetfulness and difficulty with GP access. Of concern, many students believed that the vaccine prevents any cause of meningitis.

Conclusion

High vaccine uptake is essential to protect students. Uptake at University College London is higher than at other universities in previous studies. This research highlights several areas requiring further study and has implications for university vaccination policy.

Platelet morphology
Authors: Robier Christoph
Published: June 2020

Background

The examination of a peripheral blood smear is mandatory in case of unexplained thrombocytopenia or thrombocytosis. First, the number of platelets should be estimated in order to confirm the platelet count determined by the haematology analyser, and to rule out causes of spuriously low or elevated platelet counts. Second, the size and morphological features of the platelets, which may provide information on the underlying cause of the low or enhanced platelet count, have to be assessed.

Content

This review summarizes the physiological and pathological features of platelet size and morphology, circulating megakaryocytes, micromegakaryocytes and megakaryoblasts, and provides an overview of current guidelines on the reporting of platelet morphology.

In the diagnostic work-up of a patient with thrombocytopenia, the size of the platelets is of diagnostic relevance. Thrombocytopenia with small platelets is suggestive of a defect in platelet production, whereas the presence of large platelets is more likely to be associated with enhanced platelet turnover or hereditary thrombocytopenias. Morphological platelet abnormalities may affect the granulation and the shape and are frequently associated with abnormalities of platelet size. Platelet anomalies can be found in various haematologic disorders, such as myelodysplastic syndromes, myeloproliferative neoplasms, acute megakaryoblastic leukaemia or hereditary thrombocytopenias.

Published: June 2020

Cellulose is the most abundant natural polymer on earth, which has obtained increasing interest in the field of functional materials development for its renewable, high mechanical performance and environmental benign. In this study, the traditional processing method (wet spinning and film production) of cellulose-based materials was applied by using cellulose solution for 3D printing, which can directly build complex 3D patterns. Herein, a natural cellulose is dissolved in an effective mixed aqueous solution of dimethyl sulfoxide (DMSO) and tetrabutylammonium hydroxide (TBAH). The cellulose solution extrusion was controlled by a modified fused deposition modeling (FDM) 3D printer. During the controlled extrusion 3D printing process, the viscous cellulose solution will gelifies and further solidifies into a predetermined 3D pattern at room temperature in air. Subsequently, a cellulose hydrogel skeleton was obtained, when the 3D pattern was solvent-exchanged with deionized water. Finally, the mechanical and swelling performance of the cellulose hydrogel scaffold was improved by a cross-linking agent treatment method. With treatment of the 3D printed scaffolds in 0.8 wt% cross-linking agent solution, the obtained cellulose hydrogel could absorb 28 g/g water, and the compression strength was 96 kPa. This work provided an efficient way to prepare natural cellulose hydrogel by 3D printing under room temperature.
Risk assessment of Ni, Cr, and Si release from alkaline minerals during enhanced weathering
Authors: Haque Fatima , Chiang Yi Wai , Santos Rafael M.
Published: June 2020

Calcium- and magnesium-rich alkaline silicate minerals, when applied to soil, can aid in carbon dioxide sequestration via enhanced weathering. The weathering of these silicate minerals is also associated with the release of heavy metals such as Ni and Cr, depending on the composition of the parent rock, and also labile Si. This paper critically analyses the risk associated with the release of Ni, Cr, and Si from alkaline silicate minerals as a result of enhanced weathering to evaluate its potential to be applied as a soil amendment. Based on the available data in the literature, this study evaluates the soil contamination level and quantifies the risk these elements pose to human health as well as the environment. To assess these potential threat levels, the geoaccumulation index was applied, along with the method recommended by the US Environmental Protection Agency for health risk assessment. The main findings of this study indicate the potential release of Ni, Cr, and Si to exceed the soil quality guideline value. The geochemical index suggests that the analyzed samples are in the class 0–3 and represents sites that lie between uncontaminated zones to highly contaminated zones. The hazard index value for Ni and Cr is greater than unity, which suggests that Ni and Cr release poses a non-carcinogenic risk. The probability of labile Si concentration in the soil to exceed the critical value is found to be 75%.

Published: June 2020

Maintaining yield stability in the African yam bean (AYB) (Sphenostylis stenocarpa) under year-to-year variability is crucial to its sustained productivity. Exploring yield stability in crops is vital in identifying how stable and consistent the yield of such crops is. Cultivation of AYB, an underutilized traditional legume in a specific environment, will further popularize the crop and enhance the acceptance as a cheap protein source thereby reducing hunger and malnutrition especially in regions where climate change has negatively affected legume crop production. Field trials were carried out to study the performance of 23 AYB genotypes in four-year environments. Two seeds of each genotype were sown in a single 5 m row plot spaced at 1 m between and within rows; the trial was conducted during the cropping season of 2011, 2012, 2013, and 2014 and was laid out in a randomized complete block design (RCBD) with three replications. At harvesting, five plants from each row were separately harvested; seeds of all the sampled plants in each plot were bulked and weighed, and the seed yield per plant was then determined. A combined analysis of variance (ANOVA) was performed to test for the significance of genotypes, year, and genotype by year interaction. Before combined ANOVA, a test for homogeneity of residual variances was performed using Bartlet’s test; stability of the genotypes over the years was ascertained numerically and graphically using additive main effects and multiplicative interaction and Genotype X Genotype X Environment interaction (GGE) biplot analyses. Rainfall distribution between 680 and 1,700 mm with an average temperature of 28.50°C under sandy-clay soil type supported high and stable seed yield production in AYB. This environment was found adequate during the 2014 (E1) growing season. Genotypes TSs118, TSs12, TSs109, TSs148, TSs5, TSs61, and TSs69 produced an above-average mean yield across the years and were found to be productive and stable in all the year environments. TSs82 and TSs6 with above-average mean seed and tuber yield can be considered for cultivation where seed and tuber dual-purpose production is to be maximized, while TSs111, TSs49, and TSs96 with high tuber yield ranking above average total tuber yield can be further enhanced for tuber production.

Published: June 2020

Selenium nanoparticles (Se NPs) have predominant characteristics compared to that in their bulk usage due to their high surface-to-volume ratio. The walnut (Juglans regia L.) leaf extract containing different bioactive compounds that act as reductant and stabilizing agents has been used for the green synthesis of the Se NPs. Influences of two synthetic variables, namely, the amount of selenium salt solution ranging from 15 to 25 mL and the amount of walnut leaf extract ranging from 1 to 5 mL, on broad emission peak (λ
max) and absorbance of colloidal solutions having Se NPs were evaluated via the response surface methodology. Obtained results indicated that using microwave radiation (800 W for 4 min) and 5 mL of walnut leaf extract and 15 mL of selenium salt solution, Se NPs with λ
max, absorbance, particle size, polydispersity index, and zeta potential values of 375 nm, 3.65% absorbance unit (a.u.), 208 nm, 0.206, and −24.7 mV were synthesized, which had high bactericidal activity toward Escherichia coli and Staphylococcus aureus. The transmission electron microscopy analysis also indicated that spherical and monodispersed Se NPs with a mean particle size of 150 nm were formed using the walnut leaf extract.

The aim of the study was to determine the frequency of Campylobacter spp. bacteria occurrence in female Hutsul horses, and the presence of selected virulence genes and resistance to antibiotics among the isolates obtained in the experiment. One hundred (n = 100) healthy mares were tested. Campylobacter spp. bacteria were found in 9 (n = 9) animals, 89% (n = 8) of which were described as C. jejuni. There were no C. coli or C. lari found. Analyses of C. jejuni isolates revealed the presence of selected virulence genes in the following order: cadF (n = 5), cdtA (n = 1) and cdtB (n = 3). The following antibiotics were used to test the antibiotic resistance of the bacteria: ampicillin (AMP), ciprofloxacin (CIP), erythromycin (E), gentamicin (GE), meropenem (MEM) and tetracycline (TE). C. jejuni were completely sensitive to ciprofloxacin, gentamicin, meropenem, and tetracycline.
Eine neue solidarische Grundsicherung
Authors: Schöb Ronnie
Published: June 2020

Ein moderner und nachhaltiger Sozialstaat braucht eine gesunde Mischung aus staatlicher Fürsorge und Eigenverantwortung. Die Hartz-Reformen waren ein Versuch, die richtige Mischung herzustellen, mit dem Prinzip des Förderns und Forderns in der Grundsicherung. Zahlreiche Menschen sind seither nicht mehr länger auf staatliche Fürsorge angewiesen, sondern können wieder für sich selbst sorgen. Doch zeigen sich zunehmend auch Schwächen eines in die Jahre gekommenen Grundsicherungssystems, insbesondere an den Schnittstellen zwischen seinen unterschiedlichen Instrumenten. Ronnie Schöb entwickelt eine neue Grundsicherungsarchitektur, die das vorhandene Instrumentarium der Sozialpolitik besser nutzt und aufeinander abstimmt. Sie setzt an einer ursachenorientierten Existenzsicherung an. Drei Eckpunkte charakterisieren das neue System: (1) eine zu versteuernde Kindergrundsicherung, die Familien stärker als bislang unterstützt, (2) eine Wohnbedarfssicherung und (3) eine Regelbedarfssicherung für Erwerbsfähige. Die neuen Grundsicherungsleistungen sind so miteinander verzahnt, dass die Schnittstellenprobleme nicht mehr auftreten und zugleich der Anreiz zur Selbsthilfe gegenüber dem jetzigen System deutlich gestärkt wird.
Papyrusmaterial aus Elephantine und seine signifikanten Merkmale
Authors: Krutzsch Myriam
Published: June 2020

Decades of restorational processing of the writing surface, papyrus, have resulted in observations of detailed material structures that can vary depending on the production site. This paper presents characteristic traits of the papyrus material that comes from Elephantine manufactories. This material is clearly distinct from material from other places, for example Thebes, Illahun, and Tebtunis. The differences lie less in the various color nuances than in the papyruses’ general physical characteristics, fiber structure, and special surfaces. All visual observations and all simple measurements made so far have received support from natural-scientific investigations for quite some time now.
L’iconicité des hiéroglyphes égyptiens
Authors: Thuault Simon
Published: June 2020

Although mutilation is a well-known process of Egyptian hieroglyphic writing system, its involvement in signs’ figurativity and iconicity has benefited of less attention. Yet, the mutilation practice could have deep consequences for the grammatological nature of hieroglyphs, implying alterations in our analysis of the whole Egyptian scriptural functioning. Thus, this paper aims to shed light, through examples of mutilated signs, on the iconic essence of the affected hieroglyphs: does the alteration of a sign impact its iconicity and, due to this, its raison d’être in a clause or a lexeme? Since there are kinds of mutilation, do they result in various implications in our linguistic analysis of the sign? Moreover, what metonymical relations can we observe in this process? These linguistic and psychological issues will allow to complete our understanding of the mutilation practice and, consequently, of the essence of hieroglyphic signs.

Admissibility conditions for Riemann data in shallow water theory
Authors: Paulsen Martin O. , Kalisch Henrik
Published: June 2020

Consideration is given to the shallow-water equations, a hyperbolic system modeling the propagation of long waves at the surface of an incompressible inviscible fluid of constant depth. It is well known that the solution of the Riemann problem associated to this system may feature dry states for some configurations of the Riemann data. This article will discuss various scenarios in which the Riemann problem for the shallow water system arises in a physically reasonable sense. In particular, it will be shown that if certain physical assumptions on the disposition of the Riemann data are made, then dry states can be avoided in the solution of the Riemann problem.
representaciones de la mujer de talla grande en la publicidad: caso Forever 21
Authors: Vargas Ortiz Noemi
Published: June 2020

La representación física de la mujer es un tema trascendental en la publicidad. Algunas marcas han apostado por modelos atípicas, que muestran lo que parece diferente, pero es común y real. Dentro de ellas se encuentran las modelos de talla grande y esta investigación analiza sus representaciones en la publicidad de la marca estadounidense Forever 21. El objetivo es determinar si se ha promovido, aceptado y valorado el concepto de talla grande como una nueva representación de belleza. Se procede con una investigación en dos fases. La primera identifica las representaciones generales de la mujer de talla grande en la publicidad, explicando cómo se han incorporado nuevos roles. Para ello se recurre a diversas fuentes documentales para observar cómo la publicidad es promotora de estereotipos y estilos de vida. La segunda parte indaga en la publicidad de Forever 21, en su cuenta oficial de Instagram, con un análisis hermenéutico basado en el modelo de Julio Amador Bech, al que se agregan cuestiones de tipografía, planos, ángulos y tomas. Se tomaron en cuenta las imágenes publicadas durante tres meses, del 1 de marzo al 30 de mayo de 2018, observando que sólo 26 imágenes de las 682 publicadas incluyen modelos de talla grande. Esto representa un 3,8% de los posts. Sólo se eligieron las imágenes donde aparecen, a la vez, las modelos La'Tecia Thomas (de talla grande) y Fiona Barron. Esto permite, a simple vista, hacer una comparación, y nos sugiere un análisis muy rico, inédito y original.

Published: June 2020

La presente investigación surge de la necesidad de aportar a la sociedad herramientas útiles para la alfabetización mediática de los individuos ante un mundo inundado por tecnologías audiovisuales. Y es que, se hace necesario un sistema educativo que evolucione de forma paralela a los cambios que se originan fuera de éste y para ello, entre otros, se debe recurrir a aquellos lenguajes que el alumnado utiliza, con el propósito de incentivar la motivación, pero sin olvidar la necesidad de educarlo con una actitud crítica donde reflexione y se cuestione. A partir de la práctica docente, desarrollada en dos talleres extraescolares con alumnos de secundaria de un I.E.S. de Madrid y un I.E.S. de Murcia con alumnos de Altas Capacidades, a partir de una investigación comparada (cuantitativa y cualitativa), analizaremos los resultados de una metodología educativa de las competencias mediáticas a través del videoarte, con el propósito de animar a otros docentes a utilizar la alfabetización mediática dentro de su aula. Esta alfabetización se rige por la estructura semántica del audiovisual para su inclusión en el currículo escolar de manera trasversal. El docente podrá adaptar a su programación todos aquellos aspectos que el audiovisual aporta para la construcción del pensamiento crítico.
Dyssynchrony Induced by Ventricular Preexcitation: A Risk Factor for the Development of Dilated Cardiomyopathy
Authors: Dai Chencheng , Guo Baojing , Han Ling , Sang Caihua , Dong Jianzeng , Ma Changsheng
Published: June 2020

Background: Significant left ventricular dysfunction may arise in right-sided accessory pathways with ventricular preexcitation in the absence of recurrent or incessant tachycardia. This has just been realized and not enough attention has been paid to it.

Methods: In the last 7 years, we identified 12 consecutive children with a diagnosis of ventricular preexcitation–induced dilated cardiomyopathy. This report describes the clinical and echocardiographic characteristics of the patients before and after ablation.

Results: Dyssynchronous ventricular contraction was observed by M-mode echocardiography and two-dimensional strain analysis in all patients. The basal and middle segments of the interventricular septum became thin and moved similarly to an aneurysm, with typical bulging during the end of systole. The locations of the accessory pathways were the right-sided septum (n=5) and the free wall (n=7). Left ventricular synchrony was obtained shortly after ablation. The left ventricular function recovered to normal and the left ventricular end-diastolic diameter decreased gradually during follow-up.

Conclusions: A causal relationship between ventricular preexcitation and the development of dilated cardiomyopathy is supported by the complete recovery of left ventricular function and reversed left ventricular remodeling after the loss of ventricular preexcitation. Preexcitation-related dyssynchrony was thought to be the crucial mechanism. Ventricular preexcitation–induced dilated cardiomyopathy is an indication for ablation with a good prognosis.

Air temperature and precipitation analyses on a small Mediterranean island: the case of the remote island of Lastovo (Adriatic Sea, Croatia)
Authors: Bonacci Ognjen
Published: June 2020

The paper analyses a series of annual, monthly, and daily air temperatures, and annual and monthly precipitation at the Lastovo meteorological station on the island of Lastovo (Croatia) during the 1948-2018 period. The small carbonate Adriatic island of Lastovo is the most remote inhabited island in the Croatian part of the Adriatic Sea. The absolute minimum annual air temperatures range between -6.8 °C (recorded in 1963) and 4.0 °C (recorded in 1974), with an average value of -1.2 °C. The Mean annual air temperatures range between 14.7 °C (recorded in 1980) and 17.4 °C (recorded in 2018), with an average value of 15.8 °C. The absolute maximum annual air temperatures range between 31.7 °C (recorded in 1959) and 38.3 °C (recorded in 1998), with an average value of 34.8 °C. A strong jump in the minimum annual temperatures started in 1972. The mean annual temperature jump began nine years later in 1981, while the maximum annual temperature jump occurred in 1992. The values of the t-test for all three analysed annual temperature indices (ATI) substantiate the conclusion that the average values in two subperiods defined by the RAPS method are statistically significant at the level p<<0.01. The increasing trend of air temperatures is significantly higher for the time series of the average maximum temperature Tmax than for the time series of the average minimum temperature Tmin. The most prominent increasing trend occurs in June and July. The number of warm and hot days in Lastovo has continuously increased over the analysed period. The increasing trends for both indices are statistically significant at the level p<0.01. The day-to-day (DTD) method established a decrease in the night-time to night-time variability, and an increase in the day-time to day-time temperature variability. The number of frost days is steadily decreasing. The average annual precipitation in the 1948-2018 period was 666 mm, while the minimum and the maximum precipitation was 368 mm and 1089 mm, respectively. No trends have been established for the annual and the monthly precipitation time-series during the 1948-2018 period, though a statistically insignificant drop in annual precipitation is found after 1982.

Authors: Firkavičiūtė Karina
Published: June 2020

Šiame straipsnyje autorė nagrinėja liturgijos ir muzikos santykį Lietuvos karaimų dievogarboje. Tai pirmas tokio pobūdžio analitinis darbas, sistemiškai ir ivairiais aspektais žvelgiantis į šias dvi karaimų kultūrinio palikimo dalis Lietuvoje. Jų sąsajos buvo pirmiausia suformuotos religinių kanonų. Griežto tradicijų laikymosi dėka išliko daugmaž visas liturgijos ritualas, atskleidžiantis nemažai unikalių muzikos ir pačios liturgijos sistemos savybių. Nagrinėjimui pasitelkti redukcijos bei palyginimo metodai. Lietuvos karaimų muzikinei tradicijai iki šiol (išskyrus kitus šios autorės darbus) nebuvo skirta deramo dėmesio. Šiame rašinyje ir ji tęsiančioje autorės daktarinėje disertacijoje siekiama užfiksuoti ir išnagrinėti ypatingąsias karaimų muzikinio palikimo gyvavimo formas.

Terms of Intentionality in Early Prajñāpãramitā Texts (“Phenomenal Reality” (dmigs pa), “Abiding” (gnas pa) and “Practice” (spyod))
Authors: Korobov Vladimir
Published: June 2020

The paper focuses on the connection of some Prajñāpãramitā terms with the conception of intentionality as it is presented in modern phenomenology. Three terms: dmigs pa - “phenomenal reality”, gnas pa - “abiding” and spyod - “practice” are taken to demonstrate specific intentional context of Prajñāpãramitā teaching. The interpretation of these terms in the context of a whole teaching shows that the culmination of all Prajñāpãramitā phenomenology is the access to the state beyond intentional constructions and representations. The teaching itself is not a presentation of a new ontology but a “leveling” of the field of present awareness which is deformed by intentional references.
Divine Rites and Philosophy in Neoplatonism
Authors: Uždavinys Algis
Published: June 2020

The essay deals with the problem of relationship between philosophy and ritual in late antiquity and attempts at showing that their close connections in Neoplatonism were determined not only by their common anagogic and mystic aim (homoiosis theo ideal), but also by distant origins of philosophy (in the form of traditional wisdom and hermeneutics: explanations of oracles, omens, riddles, rites, and events) from the integral unit of the cosmogonical and ‘seasonal’ (or rather metaphysical) ritual-and-myth complexes. Philosophy in her most ancient sense and under different names can be regarded as a semi-theurgic activity (framed by the particular world-model and the archaic conception of language) inseparable from the ‘divinely sanctioned’ lawmaking, ruling, healing and fighting. Even the much later syllogistic procedures and dialectical operations in some formal respect resembled ritualistic activities as if imitating certain ‘rhythmical’ patterns of proper behaviour in the context of the harmonious whole governed by the cosmic order or divine intelligence. Despite the well-known prejudices of the one-sided post-Enlightenment scholars against rites and liturgies, their own zealous pedantry and strive for classifications, rules, and systems could be interpreted in the light of ancient rituals (always strict and dogmatic in every detail) and sacrifices. The integration of some religious cults, symbols, and mysteries into the body of the post-lamblichean Neoplatonism cannot be regarded as an artificial undertaking directed against the supposed ‘rationalist purity’, itself partly invented by the Modern Western scholars. Rather it should be understood as the peacefull sumphonia of the maximally employed human reason and ineffable divine mysteries, including all practical and contemplative (or aesthetic) sides of life.

Saulės kulto apraiškos armėnų ir lietuvių kryžiuose
Authors: Zabulytė Jolanta
Published: June 2020

Straipsnyje aptariami savitų krikščioniškųjų sakralinių paminklų - armėnų chačkarų ir lietuvių medinių kryžių - soliarinių ornamentų kilmės bei jų semantikos klausimai. Soliarinių motyvų atsiradimą ir populiarumą sunku vienareikšmikai priskirti vienos ar kitos religijos sričiai. Viena vertus, senovės Irano veikiami armėnų mitologiniai vaizdiniai ir archajinės pasaulėžiūros liekanos lietuvių pasaulėžiūroje nulėmė soliarinių motyvų vaidmens aktualumą bei savitų dekoro formų dominantę, o kita vertus, tai atitiko ir naujomis prasmėmis papildė krikščionių religijos ikonografiją, todėl galima teigti, kad religinio sinkretizmo plotmėje ios simbolinės sistemos susiliejo vienos sakralijos erdvėje.

Play of the Subconscious: on the Saṃskāras and Vāsanās in Classical Yoga Psychology
Authors: Beinorius Audrius
Published: June 2020

The present study attempts to deepen the existing scholarly understanding of the various conceptual issues related to the problem of unconscious in Indian philosophy. An attempt is made to determine and classify the semantic content of a selected number of psychological concepts, notably saṃskãras and vāsanās, as it is found in the philosophical and religious texts of Patañjali’s Yoga sūtra and the basic commentarial literature thereon. Seven main features, or functions, of these concepts in Yoga tradition are distinguished. Finally, some significant differences between Yoga psychology and Western psycho-analysis regarding the understanding of the nature of the subconscious are mentioned. The most important point of similarity is that according to both Yoga and psychoanalysis the subconscious is regarded as the determining factor in conscious life. Belonging to the core of the Indian psychological system, the conception of saṃskãras and vāsanās in a way foreshadows the modem notion of the subconscious / unconscious / preconscious.
