Alloys of the quasi-binary TiNi – TiCu system with a copper content of 25, 30, 35, and 40 at. % were obtained by planar flow casting technique at a cooling rate of 10^6 K/s in the form of ribbons 30–50 μm thick and 10–20 mm wide. The structure and phase transformations in the alloys were studied using electron microscopy, X-ray diffraction analysis, and differential scanning calorimetry. It was found that in the initial state, the alloys with 25 and 30 at.% Cu have an amorphous-crystalline structure, undergoing a one-stage polymorphic crystallization of the amorphous state on heating in a calorimeter with the formation of austenite B2 phase, which on cooling to room temperature proceeds to orthorhombic B19 phase due to the martensitic transformation. It is shown that the alloys with 35 and 40 at.% Cu at quenching become amorphous, and upon heating, two-stage crystallization occurs (primary and eutectic) with the formation of a two-phase structure - the tetragonal B11 (TiCu) phase with a small fraction of B2 phase. Moreover, an increase in the copper content leads to a decrease in the onset temperature of crystallization.

Abstract The elastocaloric effect (ECE) is studied in samples of rapidly quenched ribbons of a Ti_2NiCu alloy at a periodic action by a mechanical stress to 300 MPa at a frequency to 50 Hz. ECE is maximal near the temperatures of a first-order thermoelastic martensitic phase transition. The ECE maximum is observed in a point corresponding to the completion of the reverse martensitic transition ( T = 67.5°C) and is 21 and 6 K at cyclic mechanical loads of 300 and 100 MPa, respectively. The ECE value is shown to be independent of the frequency of the external loads in the range from 0 to 50 Hz. The specific power of a rapidly quenched ribbon as a thermal energy transformer is estimated at the external mechanical stress of 100 MPa; its value is 150 W/g at a frequency of 50 Hz and ECE is 6 K.

Abstract Several scenarios of formation of hydrodynamic flows in nanoscale planar-oriented liquid-crystal (POLC) channels are described by numerical methods within nonlinear generalization of the classical Ericksen–Leslie theory, which allows for consideration of thermomechanical contributions both to the expression for shear stress and the equation of entropy balance. A vortex flow can eventually be formed in a nanoscale POLC channel as a result of the formation of both temperature gradient ∇ T (in the initially uniformly heated POLC channel under focused laser irradiation) and director field gradient $$\nabla {\mathbf{\hat {n}}}$$ (under a static electric field arising in the natural way at the LC phase/solid interface) and due to the interaction between ∇ T and $$\nabla {\mathbf{\hat {n}}}$$ .

The first-principle calculations of the atomic and electronic structures and cohesion energy of fullerene-like Si60C60 clusters have been carried out. A model of two-layer fullerene-like Si12C12@Si48C48 cluster with mixed sp2/sp3 bonds has been built for the first time. Ab initio calculations are performed in terms of the electron density functional and the hybrid B3LYP functional theory. The stability and the energy gap width of the clusters are estimated in the dependence on its geometry. It is shown that cohesion energy of two-layer fullerene-like Si12C12@Si48C48 cluster exceeds the cohesion energy of the other fullerene-like clusters with the same number of atoms, but is inferior to the SiC cluster with sphalerite structure. The relaxation of two-layer cluster is shift on outward the surface layer occurs.
Selecting Evidence-Based Content for Inclusion in Self-Management Apps for Pressure Injuries in Individuals With Spinal Cord Injury: Participatory Design Study
Authors: Fiordelli Maddalena , Zanini Claudia , Amann Julia , Scheel-Sailer Anke , Brach Mirjam , Stucki Gerold , Rubinelli Sara
Published: March 2020

Background

Technological solutions, particularly mobile health (mHealth), have been shown to be potentially viable approaches for sustaining individuals’ self-management of chronic health conditions. Theory-based interventions are more successful, as evidence-based information is an essential prerequisite for appropriate self-management. However, several reviews have shown that many existing mobile apps fail to be either theoretically grounded or based on evidence. Although some authors have attempted to address these two issues by focusing on the design and development processes of apps, concrete efforts to systematically select evidence-based content are scant.

Objective

The objective of this study was to present a procedure for the participatory identification of evidence-based content to ground the development of a self-management app.

Methods

To illustrate the procedure, we focused on the prevention and management of pressure injuries (PIs) in individuals with spinal cord injury (SCI). The procedure involves the following three steps: (1) identification of existing evidence through review and synthesis of existing recommendations on the prevention and self-management of PIs in SCI; (2) a consensus meeting with experts from the field of SCI and individuals with SCI to select the recommendations that are relevant and applicable to community-dwelling individuals in their daily lives; and (3) consolidation of the results of the study.

Results

In this case study, at the end of the three-step procedure, the content for an mHealth intervention was selected in the form of 98 recommendations.

Conclusions

This study describes a procedure for the participatory identification and selection of disease-specific evidence and professional best practices to inform self-management interventions. This procedure might be especially useful in cases of complex chronic health conditions, as every recommendation in these cases needs to be evaluated and considered in light of all other self-management requirements. Hence, the agreement of experts and affected individuals is essential to ensure the selection of evidence-based content that is considered to be relevant and applicable.
Development and Performance of a Web-Based Tool to Adjust Urine Toxicology Testing Frequency: Retrospective Study
Authors: Chapman Kenneth B , Pas Martijn M , Abrar Diana , Day Wesley , Vissers Kris C , van Helmond Noud
Published: March 2020

Background

Several pain management guidelines recommend regular urine drug testing (UDT) in patients who are being treated with chronic opioid analgesic therapy (COAT) to monitor compliance and improve safety. Guidelines also recommend more frequent testing in patients who are at high risk of adverse events related to COAT; however, there is no consensus on how to identify high-risk patients or on the testing frequency that should be used. Using previously described clinical risk factors for UDT results that are inconsistent with the prescribed COAT, we developed a web-based tool to adjust drug testing frequency in patients treated with COAT.

Objective

The objective of this study was to evaluate a risk stratification tool, the UDT Randomizer, to adjust UDT frequency in patients treated with COAT.

Methods

Patients were stratified using an algorithm based on readily available clinical risk factors into categories of presumed low, moderate, high, and high+ risk of presenting with UDT results inconsistent with the prescribed COAT. The algorithm was integrated in a website to facilitate adoption across practice sites. To test the performance of this algorithm, we performed a retrospective analysis of patients treated with COAT between June 2016 and June 2017. The primary outcome was compliance with the prescribed COAT as defined by UDT results consistent with the prescribed COAT.

Results

979 drug tests (867 UDT, 88.6%; 112 oral fluid testing, 11.4%) were performed in 320 patients. An inconsistent drug test result was registered in 76/979 tests (7.8%). The incidences of inconsistent test results across the risk tool categories were 7/160 (4.4%) in the low risk category, 32/349 (9.2%) in the moderate risk category, 28/338 (8.3%) in the high risk category, and 9/132 (6.8%) in the high+ risk category. Generalized estimating equation analysis demonstrated that the moderate risk (odds ratio (OR) 2.1, 95% CI 0.9-5.0; P=.10), high risk (OR 2.0, 95% CI 0.8-5.0; P=.14), and high risk+ (OR 2.0, 95% CI 0.7-5.6; P=.20) categories were associated with a nonsignificantly increased risk of inconsistency vs the low risk category.

Conclusions

The developed tool stratified patients during individual visits into risk categories of presenting with drug testing results inconsistent with the prescribed COAT; the higher risk categories showed nonsignificantly higher risk compared to the low risk category. Further development of the tool with additional risk factors in a larger cohort may further clarify and enhance its performance.

Published: March 2020

Background

Prognostic genes or gene signatures have been widely used to predict patient survival and aid in making decisions pertaining to therapeutic actions. Although some web-based survival analysis tools have been developed, they have several limitations.

Objective

Taking these limitations into account, we developed ESurv (Easy, Effective, and Excellent Survival analysis tool), a web-based tool that can perform advanced survival analyses using user-derived data or data from The Cancer Genome Atlas (TCGA). Users can conduct univariate analyses and grouped variable selections using multiomics data from TCGA.

Methods

We used R to code survival analyses based on multiomics data from TCGA. To perform these analyses, we excluded patients and genes that had insufficient information. Clinical variables were classified as 0 and 1 when there were two categories (for example, chemotherapy: no or yes), and dummy variables were used where features had 3 or more outcomes (for example, with respect to laterality: right, left, or bilateral).

Results

Through univariate analyses, ESurv can identify the prognostic significance for single genes using the survival curve (median or optimal cutoff), area under the curve (AUC) with C statistics, and receiver operating characteristics (ROC). Users can obtain prognostic variable signatures based on multiomics data from clinical variables or grouped variable selections (lasso, elastic net regularization, and network-regularized high-dimensional Cox-regression) and select the same outputs as above. In addition, users can create custom gene signatures for specific cancers using various genes of interest. One of the most important functions of ESurv is that users can perform all survival analyses using their own data.

Conclusions

Using advanced statistical techniques suitable for high-dimensional data, including genetic data, and integrated survival analysis, ESurv overcomes the limitations of previous web-based tools and will help biomedical researchers easily perform complex survival analyses.
Privacy Protection in Online Health Communities: Natural Experimental Empirical Study
Authors: Dang Yuanyuan , Guo Shanshan , Guo Xitong , Vogel Doug
Published: March 2020

Background

An online health community (OHC) is a novel sharing channel through which doctors share professional health care knowledge with patients. While doctors have the authority to protect their patients’ privacy in OHCs, we have limited information on how doctors’ privacy protection choices affect their professional health care knowledge sharing with patients.

Objective

We examined the relationship between privacy protection and professional health care knowledge sharing in OHCs. Specifically, we examined the effects of privacy protection settings in an OHC on doctors’ interactive professional health care knowledge sharing and searching professional health care knowledge sharing (two dimensions of professional health care knowledge sharing). Moreover, we explored how such effects differ across different levels of disease stigma.

Methods

We collected the monthly panel data of 19,456 doctors from Good Doctor, one of the largest OHCs in China, from January 2008 to April 2016. A natural experimental empirical study with difference-in-difference analysis was conducted to test our hypotheses. The time fixed effect and the individual fixed effect were both considered to better identify the effects of a privacy protection setting on professional health care knowledge sharing. Additionally, a cross-sectional analysis was performed for a robust check.

Results

The results indicate that the privacy protection setting has a significant positive effect on interactive professional health care knowledge sharing (β=.123, P<.001). However, the privacy protection setting has a significant negative effect on searching professional health care knowledge sharing (β=–.225, P=.05). Moreover, we found that high disease stigma positively impacts the effect of privacy protection on interactive professional health care knowledge sharing (coefficients are in the same valence) and negatively impacts the effects of privacy protection on searching professional health care knowledge sharing (coefficients are in the reverse valence).

Conclusions

Privacy protection has a bilateral effect on professional health care knowledge sharing (ie, a positive effect on interactive professional health care knowledge sharing and a negative effect on searching professional health care knowledge sharing). Such bilateral switches of professional health care knowledge sharing call for a balanced state in conjunction with practical implications. This research also identifies a moderate effect of disease stigma on privacy protection settings and professional health care knowledge sharing.
Privacy Assessment in Mobile Health Apps: Scoping Review (Preprint)
Authors: Benjumea Jaime , Ropero Jorge , Rivera-Romero Octavio , Dorronzoro-Zubiete Enrique , Carrasco Alejandro
Published: March 2020

BACKGROUND

Privacy has always been a concern, especially in the health domain. The proliferation of mobile health (mHealth) apps has led to a large amount of sensitive data being generated. Some authors have performed privacy assessments of mHealth apps. They have evaluated diverse privacy components; however, different authors have used different criteria for their assessments.

OBJECTIVE

This scoping review aims to understand how privacy is assessed for mHealth apps, focusing on the components, scales, criteria, and scoring methods used. A simple taxonomy to categorize the privacy assessments of mHealth apps based on component evaluation is also proposed.

METHODS

We followed the methodology defined by Arksey and O’Malley to conduct a scoping review. Included studies were categorized based on the privacy component, which was assessed using the proposed taxonomy.

RESULTS

The database searches retrieved a total of 710 citations—24 of them met the defined selection criteria, and data were extracted from them. Even though the inclusion criteria considered articles published since 2009, all the studies that were ultimately included were published from 2014 onward. Although 12 papers out of 24 (50%) analyzed only privacy, 8 (33%) analyzed both privacy and security. Moreover, 4 papers (17%) analyzed full apps, with privacy being just part of the assessment. The evaluation criteria used by authors were heterogeneous and were based on their experience, the literature, and/or existing legal frameworks. Regarding the set of items used for the assessments, each article defined a different one. Items included app permissions, analysis of the destination, analysis of the content of communications, study of the privacy policy, use of remote storage, and existence of a password to access the app, among many others. Most of the included studies provided a scoring method that enables the comparison of privacy among apps.

CONCLUSIONS

The privacy assessment of mHealth apps is a complex task, as the criteria used by different authors for their evaluations are very heterogeneous. Although some studies about privacy assessment have been conducted, a very large set of items to evaluate privacy has been used up until now. In-app information and privacy policies are primarily utilized by the scientific community to extract privacy information from mHealth apps. The creation of a scale based on more objective criteria is a desirable step forward for privacy assessment in the future.

Published: March 2020

UNSTRUCTURED

Previous epidemic management research proves the importance of city-level information, but also highlights limited expertise in urban data applications during a pandemic outbreak. In this paper, we provide an overview of city-level information, in combination with analytical and operational capacity, that define urban intelligence for supporting response to disease outbreaks. We present five components (movement, facilities, people, information, and engagement) that have been previously investigated but remain siloed to successfully orchestrate an integrated pandemic response. Reflecting on the coronavirus disease (COVID-19) outbreak that was first identified in Wuhan, China, we discuss the opportunities, technical challenges, and foreseeable controversies for deploying urban intelligence during a pandemic. Finally, we emphasize the urgency of building urban intelligence through cross-disciplinary research and collaborative practice on a global scale.

Published: March 2020

The aim of this paper is to present several approaches by which technology can assist medical decision-making. This is an essential, but also a difficult activity, which implies a large number of medical and technical aspects. But, more important, it involves humans: on the one hand, the patient, who has a medical problem and who requires the best solution; on the other hand, the physician, who should be able to provide, in any circumstances, a decision or a prediction regarding the current and the future medical status of the patient. The technology, in general, and particularly the Artificial Intelligence (AI) tools could help both of them, and it is assisted by appropriate theory regarding modeling tools. One of the most powerful mechanisms that can be used in this field is the Artificial Neural Networks (ANNs). This paper presents some of the results obtained by the Process Control group of the Politehnica University Timisoara, Romania, in the field of ANNs applied to modeling, prediction and decision-making related to medical systems. An Iterative Learning Control-based approach to batch training a feedforward ANN architecture is given. The paper includes authors’ concerns in this domain and emphasizes that these intelligent models, even if they are artificial, are able to make decisions, being useful tools for prevention, early detection and personalized healthcare.

Authors: Tomov Pancho , Dimitrov Lubomir
Published: March 2020

Intelligent production is the future of industrial production. It is the leading way to a new industrial era and it best defines the concept of the Fourth Industrial Revolution. Getting the real-time data on quality, resources and costs it provides significant advantages over classical production systems. Intelligent production must be built on sustainable and service-oriented technological and business practices. They are characterized by flexibility, adaptability and self-learning, resilience to failures, and risk management. The high levels of automation, on the other hand, become a mandatory standard for them, which is possible thanks to a flexible network of production-based systems that automatically monitor the production processes. Flexible systems and models that are capable of responding in real time allow internal processes to be radically optimized. Production benefits are not limited to one-off production conditions, and the capabilities include optimization through a global network of adaptive and self-regulating manufacturing components belonging to more than one operator.
EXPERIMENTAL INVESTIGATION OF THE INFLUENCE OF TRAIN VELOCITY AND TRAVEL DIRECTION ON THE DYNAMIC BEHAVIOR OF STIFF COMMON CROSSINGS
Authors: Kovalchuk Vitalii , Sysyn Mykola , Gerber Ulf , Nabochenko Olga , Zarour Jandab , Dehne Stefan
Published: March 2020

Common crossing rails are subjected to a rapid deterioration of the rolling surface due to a dynamic loading of trains. The present study is devoted to an experimental study of the displacement and rail strain measurements in the common crossing. The experimental measurements were carried out for two stiff common crossings under the dynamic loading of high-speed train for the velocity range of 54-254 km/h. The results showed 2.5 times increase of the maximal displacements within the velocity range. The absence of the difference in the displacements between the trailing and the facing travel direction is explained with the relative displacement measurements between the rail and the sleeper and the different dynamic impact loading for the wing rail. The proposed model-based analysis of the absolute measurement of rail strain enables us to estimate the dynamic factor under the impact loading. The wing rail for trailing direction is almost twice as highly loaded as the frog rail for the facing direction. The maximal dynamic factor for the trailing direction shows almost no change for the velocities of more than 200 km/h.

Tropospheric nitrogen dioxide (NO2) is a trace gas with important impact on atmospheric chemistry, human health and a key pollutant in particular cities, measured from space since the mid-1990s by the GOME, SCIAMACHY, OMI, and GOME-2 instruments. This study present ten years (monthly and yearly averaged) dataset from Ozone Monitoring Instrument (OMI) used to investigate tropospheric NO2 characteristics and variations over Iraq during 2005–2014. Annual NO2 shows an elevation from the northern to the southern and highest values was at central parts of Iraq. Monthly distributions revels higher values NO2 in winter and summer than spring and autumn seasons, and rising NO2 throughout study period over industrial and crowded urban zones. The trend analysis over Baghdad shows a linear growth rate 9.8% per year with an annual average (5.6·1015 molecules per 1 cm2). The air mass trajectory analysis as hotspot regions shows seasonal fluctuations between winter and summer seasons depend on weather conditions and topography. The increased NO2 values in winter are due to anthropogenic emissions and subsequent plumes from Europe. In addition, in summer because of hot weather and large paddy fields emissions. The lowest NO2 value was at monsoon period mostly linked to the rains. The OMI data and satellite information are able to observe the troposphere NO2 elevation at different regions.

Authors: Zhao Xiangyang
Published: March 2020

To improve the service life and performance of lithium cells in new energy electric vehicles, the thermal management system of lithium cells in new energy vehicles is analyzed through simulation experiments in this research. Firstly, the calculation model of set of cells and cooling structure is built, and then a lithium cell management system is designed. On this basis, the cooling structure of lithium cell is optimized. Finally, the simulation results of the calculation model and the simulation results of the heat dissipation performance of the thermal management system in the cooling structure of lithium cell are analyzed, including influence of three factors (coolant flow, inlet temperature of coolant, and discharge multiple) on the heat dissipation of the thermal management system of lithium cell. The results show that the calculation model constructed in this research is feasible. When the optimal structure, coolant flow value, inlet temperature of coolant, and discharge multiple are determined, the thermal management system of lithium cell has a good cooling effect under the optimal parameters. Therefore, the results of this research can provide a good theoretical basis for heat management and heat dispersion technology in new energy electric vehicles.
Application of energy-saving structural design under numerical simulation in solar heating buildings
Authors: Li Yang
Published: March 2020

The research is to explore the changes in solar heating buildings under energy-saving structural design. This paper analyzes the changes in solar heating buildings under energy-saving structural design by constructing a numerical simulation method. It mainly studies the effects of the space temperature of the house, different thermal insulation methods, and wall thermal resistance on solar heating buildings. The energy-saving structural design mainly includes expanding the area of exterior windows, increasing heat retainers, adopting energy-saving walls, and improving the building envelope. The results show that after the energy-saving structural design, the indoor temperature of the solar heating building after the renovation has been greatly increased, with an average increase of about 6 ?C. Compared with the external insulation and internal insulation modes, the solar heating building under the sandwich insulation mode has the best effect, and the room temperature increases the most. Also, it shows that the east wall, west wall, and north wall of the building are increasing the energy saving per unit area of the wall as the wall thermal resistance increases. The difference is that the increasing range of the north wall has significant advantages over the east wall and the west wall. The energy-saving structural design for solar heating buildings under the numerical simulation method has significantly improved the utilization efficiency of solar energy. It reduces the consumption of traditional fossil resources and improves the quality of the environment. This paper?s research has a positive effect on subsequent research.

Published: March 2020

In order to solve the problem that the auxiliary equipment of electric gas turbine can operate only by relying on external power, and realize the purpose that auxiliary equipment of electric gas turbine can operate independently without the external power grid, in this research, a management system of air source self-powered electric gas generator is proposed. Firstly, the process of the thermal energy management system of the air source self-powered electric gas generator is introduced, and the thermodynamic theory of the thermal energy management system of the air source self-powered electric gas generator is analyzed. Then, the experimental conditions of air source self-powered electric gas generator are introduced. Finally, the results of variable speed and terminal variable flow in heating condition and terminal variable flow in cooling condition of the thermal energy management system of air source self-powered electric gas generator are analyzed. The results show that whether the thermal energy management system of air source self-powered electric gas generator studied in this research is in heating or cooling conditions, both the output power of the engine and the power of the compressor increase with the increase of the rotating speed. It can be concluded from the variable flow results in heating conditions that the smaller the end flow is, the smaller the output power of the engine will be. In this way, the loss of heat transfer efficiency of the plate can be reduced as much as possible, and the users? demand for heat can be met.

Authors: Feng Xueli , Hu Jie
Published: March 2020

To cope with the problem of global warming and improve the performance of electric vehicles, the power source of electric vehicles is researched. First, the CFD simulation analysis method is utilized to analyze the heat dissipation effect under the changes of the air intake speed, the number of fins, and the thickness of the fins between lithium batteries. Then, the orthogonal experiment is utilized to select the optimal solution between the lithium batteries. The simulation results show that the heat dissipation effect is optimal under the conditions that the inlet air speed is 8 m/s, the number of fins is seven, and the thickness of fins is 2.5 mm. Then, the orthogonal experiment determines the optimal heat dissipation scheme of the lithium battery pack the air inlet speed is 8 m/s, the number of fins is six, and the thickness of the fins is 2 mm. This optimal scheme can effectively improve the heat dissipation performance of lithium batteries, enhance the performance of electric vehicles, and reduce CO2 emissions.

Authors: Kapor Slobodan , Puskas Laslo , Vojvodic Aleksandar , Malis Milos , Bjelogrlic Predrag , Cezayirli Enis , Chisholm Fraser , Aksic Milan , Filipovic Branislav
Published: March 2020

Background / Aim. The sciatic nerve (SN) is a mixed nerve formed in pelvis by joining of L4 - S3 anterior spinal nerve roots. SN can be under the pressure in different regions throughout its course. However, the most frequent site of impingement is under the piriformis muscle which causes the occurrence of piriformis syndrome. High division of SN has its relevance considering the fact that it leads to the compression of nerve resulting in piriformis syndrome. The aim of this study was to determine the connection be-tween anatomical parameters of pelvis and high division of SN, which is considered to be one of the most common causes of piriformis syndrome in both genders. Methods. This study was conducted on 28 formalin fixed cadavers of both genders at the Institute of Anatomy, Faculty of Medicine, University of Belgrade (Belgrade, Serbia) and the Department of Anatomy, School of Medicine, University of St Andrews (St Andrews, United Kingdom). For the measuring of required dimensions, we used a ruler and a caliper. Results. A statistically significant difference in the values of bispinal and bituberal lines was observed. A high division of SN was found on 58.33% of the male cadavers and 80% of the female cadavers. A statistically significant difference in the mean value of the bituberal line between the male and female sex was also recognised. Conclusion. The connection between the anatomical parameters of the pelvis and the level of division of the SN is confirmed. Although on the basis of the results it could be assumed that people with smaller pelvic dimensions would have greater likelihood of developing a piriformis syndrome, the other factors, such as biomechanics related to a wider ?Q angle? in women that could result in a higher incidence of piriformis syndrome, should also be considered.

Published: March 2020

The paper considers the formation conditions and the specificity of manifestation of cultural archetypes of the Russian people and their influence on the current reality. The author highlights the national features, the essential values, and problem areas of the cultural archetypes. The emphasis is placed on logocentrism as an archetypal trait, understood as a desire for the essential, authentic, and sacral. This concept reveals such basic values as the desire for truth and justice, the idea of messianism and salvation. It is noted that such archetypal landmarks form one of the most important contradictions of the Russian mentality – the dominance of internal over external. The research methodology includes the historical and sociocultural approaches. There are also applied the methods of analysis, synthesis, analogy, generalization, comparison, and systematization.

The Tibetan question, because of the strategic position of Tibet, plays a crucial role for the People’s Republic of China, which includes this alpine region of the world. The Tibetan problem has been repeatedly used by Western countries in their Chinese policy. The issue of the status of Tibet is a matter of the country’s exclusive domestic policy of the People’s Republic of China. The Tibetan Emigration doesn’t agree to this conception. The foundations of the ideology and policy of Tibetan Emigration are primarily determined by His Holiness the Dalai Lama XIV in his Five-Point Plan for Tibet. This paper, basing on the Peace Plan, describes the views of the Dalai Lama XIV on the political status of Tibet and on the problem of Chinese colonization of Tibetan lands, shows his opinion on human rights violations and ecological problems in Tibet. In addition, the United Nations position on Tibet is reflected in the paper and the correlation of opinions on priority issues of the world community and Tibetan emigration in the person of the Dalai Lama XIV is considered.

The study considers the problems of the development of subjectivity. Nowadays we can state a dramatic change in human behavior under the influence of cyberspace. The purpose of the article is to find the basis for the formation of subjectivity and moral principle. The novelty of the work is the understanding of the development of subjectivity as determinism from the initial conditions, as the trigger mechanism and the understanding of “giving” and “accepting” actions as a necessary principle in the development of personality and in the determination of basic value orientations. The principle determines the action of a human, being the content of his inner world; contributes to the self-realization of the individual and directs the activity. The methodological basis of the study was the dialectical approach, with the help of which the features of the formation of subjectivity were revealed as continuity in development and determinism. The practical significance of the study is determined by the need for a socio-value model, where the principle of “giving” and “accepting” can be used as a methodological tool for compiling programs for human development. The methodological platform allows connecting the “initial conditions” of life with the subsequent development of personality. This research setting shows that a current development depends not only on knowledge and technology, but also on the worldview, which affects not only epistemological, but anthropological parameters as a whole as well. The research perspective is also noted.

Published: March 2020

The influence of the basic theoretical and methodological settings, originating from the doctrine of the organicism. on the development of modern scientific concepts on self-organized systems (cybernetics and synergetics), which are based on a systematic approach, is analyzed in this article. It is proved that the initial settings of the organicism determinate the organic outlook and are based on the multidiscipline concepts of modern science. The organic outlook is based on the pattern of synergistic integrity and is viewed as a universal way of cognition allowing a systematic analysis of processes of reality structure through the idea of a synergistic integrity of perceived objects. It is also argued that this way of vision has significant prospects in overcoming the discreteness of modern scientific cognition. The author believes that the organic outlook is a kind of generator of ideas, concepts and theories which synthesizes disparate parts of scientific knowledge into a single system. Moreover, it greatly contributes to the creation of a holistic picture of the world which brings humanity closer to the full cognition of the universal patterns of life.
