CARBON CAPTURE AND STORAGE IN BIOMASS COMBUSTION PROCESS
Authors: Pavel Ioan , Radoi Radu , Matache Gabriela , Popescu Ana-Maria
Published: May 2021

Biomass stores solar energy that man can convert into electricity, fuel or heat, resulting in cheap, clean energy with a negative carbon balance. The use of biomass from agricultural secondary production as a potential energy source can improve soil quality and reduce greenhouse gas emissions in a complementary, non-competing way. The paper presents a piece of combustion equipment performing the burning process by biomass gasification on the TLUD (Top-Lit UpDraft) principle, from which hot air and biochar are obtained. The main function of this type of gas generator set on the TLUD principle is to generate a syngas flame which can be used as a heat source. The biochar obtained as a by-product is a sterile, active carbon with a large adsorption surface which is used as a soil amendment in environments with limited capacity for carbon sequestration and in soils depleted of resources. Gasification on the TLUD principle occurs when the biomass layer is introduced into the reactor and rests on a grate through which the air flow for gasification passes from bottom to top. Priming of the gasification process is done by igniting the upper layer of biomass in the reactor. The oxidation front continuously descends consuming the biomass in the reactor. Due to the heat radiated by the oxidation front the biomass is heated, dried, and then it enters a fast pyrolysis process from which volatiles emerge and unconverted carbon remains there. When the combustion front reached the grate, all the volatiles in the biomass were gasified and some of the carbon fixed was reduced; about 10 - 20% of the initial mass in the form of sterile charcoal, called biochar, remains on the grill. Compared to wood direct combustion or gasification combustion processes, the TLUD gasification process is characterized by very low values of the superficial velocity of gas passing through the pyrolysis front. The slow process maintains superficial velocity of the generator gas produced at very low values, which ensures reduced carrying away of free ash of approximate size below PM2.5 and maxim values of 5 mg/MJbm when leaving the burner; such values are well below the target imposed in the EU in 2015 for biomass combustion processes, which is below 25 mg/MJ. The result of monitoring the gasification process can be used to automate and optimize the TLUD process in order to achieve green energy, for carbon sequestration in the obtained biochar and to reduce greenhouse gas emissions, thus contributing to achieving efficient protection of the environment and to ensuring sustainable energy development
GEOPHYSICAL MONITORING: NEW OPPORTUNITIES TO PRESERVE ARCHITECTURAL MONUMENTS AND GREEN DESIGN IN URBAN AREAS
Authors: Slepak Zakhar
Published: May 2021

A new geophysical prospecting technique developed by the author was effectively applied for these purposes in 1994–2005 within the architectural complex of the Kazan Kremlin, a UNESCO World Heritage Site. The author has developed and successfully employed a unique gravity monitoring technique consisting in independent measurements at set points and at certain time intervals in the architectural complex of the Kazan Kremlin. The results of the geophysical monitoring and geodetic surveys conducted in open areas and inside architectural monuments offer new opportunities in preserving ancient buildings. Because geophysical monitoring can identify the negative impact of active geological processes on foundations of buildings, mitigation measures can be taken in timely manner. However, because the Kazan Kremlin is a state historical and architectural museum reserve, another objective is to maintain its exterior and renovate its green design. The above technology can also be used to analyze the technical condition of high-rise buildings, industrial facilities, underground railway systems and other structures, and significantly prolong their operating life.
INTERDISCIPLINARY APPROACHES TO CITYSPACE: FROM THE POSTMODERN TO THE GLOBAL CITY
Authors: Ciugureanu Adina
Published: May 2021

Cityspace has been the topic of urban and cultural studies for at least two decades and has opened a variety of ways to approach the city, from historical and cultural perspectives to socio-geographical, economic, religious, literary, postmodernist, post-colonial and, more recently, geo-critical ones. The article looks at the European and American city from the 1970s to the present through the lenses offered by the theoretical approaches by Edward Soja, David Harvey, Michel Foucault, Frederick Jameson, Bertrand Westphal, Manuel Castells, among others, while highlighting the specific characteristics of cityspace and citizenship, the use and misuse of living and imagined spaces in the period mentioned above. The shift from the modern city to the postmodern metropolis and global megalopolis has entailed essential changes in the views on cityspace both from the architectural perspective and from the city dweller’s perception of space in the city. How these changes have affected our lives and what the city of the future will look like are two core questions this article attempts to answer.

Published: May 2021

North American porcupines (Erethizon dorsatum) have expanded their range into central Texas and are now frequent users of caves as den sites. What remains unknown is how caves affect their home range, and their local habitat preferences. This information is important for management decisions on Joint Base San Antonio – Camp Bullis where novel and abundant porcupine scat in caves could jeopardize federally endangered cave-obligate arthropods by allowing for the invasion of less specialized terrestrial species. To better understand porcupine home range and habitat use at Camp Bullis, we trapped four porcupines at cave entrances and fitted them with GPS collars. The 95% home range averaged 71.3 ha for females and measured 420.6 ha for the male. The 50% core habitat averaged 55.4 ha for females and measured 7.4 ha for the male. Porcupines typically stayed near the den-cave trap site except when visiting more diverse mixed forest patches. At the landscape and point levels, individuals selected for forested cover and avoided open areas. At the home range level, individuals selected for bare ground and roads, which were likely used to get from the cave den site to feed at mixed forest patches. Typically solitary, individuals in this study tolerated sharing a cave. Because of the small sample size and single sampling location, this study represents a pilot study and additional research is needed to establish concrete conclusions. Should cave managers need to limit the cave use by porcupines, a cave gate, exclosure, or reduction of forested cover would make caves less desirable.

Published: May 2021

Migraine is a common disorder which is placed among the top ten reasons of years lived with disability. Cytokines are among the molecules that contribute in the pathophysiology of migraine. In the current study, we evaluated expression levels of IL-6 coding gene in the peripheral blood of 120 migraine patients (54 migraine without aura and 66 migraine with aura patients) and 40 healthy subjects. No significant difference was detected in expression of IL-6 between total migraine patients and healthy controls (Posterior beta = 0.253, P value = 0.199). The interaction effect between gender and group was significant (Posterior beta =-1.274, P value = 0.011), therefore, we conducted subgroup analysis within gender group. Such analysis revealed that while expression of this gene is not different between male patients and male controls (Posterior beta =-0.371, P value > 0.999), it was significantly over-expressed in female patients compared with female controls (Posterior beta = 0.86, P= 0.002). Expression of IL-6 was significantly higher in patients with aura compared with controls (Posterior beta = 0.63, adjusted P value = 0.019). However, expression of this cytokine coding gene was not different between patients without aura and healthy subjects (Posterior beta = 0.193, adjusted P value = 0.281). Therefore, IL-6 might be involved in the pathophysiology of migraine among females and migraine with aura among both sexes.

Authors: Cai Wen-Jie ,   Alzheimer’s Disease Neuroimaging Initiative, Tian Yan , Ma Ya-Hui , Dong Qiang , Tan Lan , Yu Jin-Tai
Published: May 2021

Background: The pathophysiological process of amyloid-β, tau deposition, and neurodegeneration of Alzheimer’s disease (AD) begin in a preclinical phase, while anxiety is associated with an increased risk of AD in preclinical phase. Objective: To examine the relationships between anxiety and amyloid-β, tau deposition, and neurodegeneration. To test the hypothesis that anxiety could predict clinical progression in the elderly without dementia. Methods: 1,400 participants from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database were included in the study and were studied over a median period of 3 years. In multivariable models, the cross-sectional and longitudinal associations between anxiety and amyloid-β PET, tau PET, and FDG PET SUVRs in participants without dementia were explored using Spearman rank correlation, logistic regression model, multiple linear regression model, Kaplan-Meier survival curves, and Cox proportional hazards model. The association between baseline anxiety and clinical progression was also explored. Results: There was a positive correlation between anxiety and amyloid-β deposition (r = 0.11, p = 0.0017) and a negative correlation between anxiety and neurodegeneration (r = –0.13, p = 0.00022). MCI participants with anxiety showed a faster clinical progression of dementia (HR = 1.56, p = 0.04). Non-anxious participants with more amyloid-β deposition or more severe neurodegeneration displayed accelerated development into anxiety (HR = 2.352, p < 0.0001; HR = 2.254, p < 0.0001). Conclusion: Anxiety was associated with amyloid-β deposition and neurodegeneration in non-dementia elderly. Anxiety in MCI predicted conversion to dementia. Anxiety may play a selective role and prediction of disease progression in the early phase of AD.
Construction of Long Noncoding RNA-Associated ceRNA Networks Reveals Potential Biomarkers in Alzheimer’s Disease
Authors: Ou Guan-yong , Lin Wen-wen , Zhao Wei-jiang
Published: May 2021

Background: Alzheimer’s disease (AD) is a chronic neurodegenerative disease that seriously impairs both cognitive and memory functions mainly in the elderly, and its incidence increases with age. Recent studies demonstrated that long noncoding RNAs (lncRNAs) play important roles in AD by acting as competing endogenous RNAs (ceRNAs). Objective: In this study, we aimed to construct lncRNA-associated ceRNA regulatory networks composed of potential biomarkers in AD based on the ceRNA hypothesis. Methods: A total of 20 genes (10 upregulated genes and 10 downregulated genes) were identified as the hub differentially expressed genes (DEGs). The functional enrichment analysis showed that the most significant pathways of DEGs involved include retrograde endocannabinoid signaling, synaptic vesicle circle, and AD. The upregulated hub genes were mainly enriched in the cytokine-cytokine receptor interaction pathway, whereas downregulated hub genes were involved in the neuroactive ligand-receptor interaction pathway. After convergent functional genomic (CFG) ranks and expression level analysis in different brain regions of hub genes, we found that CXCR4, GFAP, and GNG3 were significantly correlated with AD. We further identified crucial miRNAs and lncRNAs of targeted genes to construct lncRNA-associated ceRNA regulatory networks. Results: The results showed that two lncRNAs (NEAT1, MIAT), three miRNAs (hsa-miR-551a, hsa-miR-133b and hsa-miR-206), and two mRNA (CXCR4 and GNG3), which are highly related to AD, were preliminarily identified as potential AD biomarkers. Conclusion: Our study provides new insights for understanding the pathogenic mechanism underlying AD, which may potentially contribute to the ceRNA mechanism in AD.

The double-strip structure satisfies integral boundary conditions which are the generalization of Dirichlet and Neumann boundary conditions. The electric field, current distribution, and Total Radar Cross Sections are investigated. The results are compared with other methods and previous findings such as the Method of Moments and Physical Optics. The theoretical and numerical analyses indicate that the fractional order, the position of the line source have tremendous effects on the total-field distributions.
A PMSM fuzzy logic regenerative braking control strategy for electric vehicles
Authors: Liu Feng
Published: May 2021

Regenerative braking system is a system by which an energy conversion device is used to convert kinetic energy into electrical energy and store it in an energy storage device for use when the motor vehicle is driving. To improve the energy recovery rate of pure electric vehicles, a series regenerative braking control strategy based on PMSM fuzzy logic is proposed in this paper. According to this strategy, the motor braking shall be used as much as possible based on ensuring braking stability, 4 braking zones shall be divided according to the braking intensity, and different braking force distribution strategies shall be used, while comprehensively considering influencing factors such as vehicle speed, ECE regulations, battery, and motor characteristics. Simulink and Cruise are used for modeling and united simulation. The results show that the built model is accurate and reliable. The energy recovery rate can be improved effectively and the cruising range of pure electric vehicles can be extended based on proposed series regenerative braking control strategy.

The development of blockchain technology has introduced new elements to the logistics service supply chain, which provides solutions to the related problems in the development at present. In this paper, mainly the relevant contents of blockchain technology are analyzed. At the same time, the composition and application of the logistics service supply chain algorithm based on the blockchain technology are clarified. A fuzzy logic algorithm logistics based on the rough set visual image label tracking method is put forward for container transportation to address the problems in the application process. The overall visual features of the container are taken as the label feature, and the image segmentation transformation method is used to extract the features from the images collected from container logistics transportation, which has provided a basis for the logistics transportation visual tracking. The background is separated based on the key feature frames of the container images collected. The separated features are recorded, and the similarity of the features is used to complete the visual tracking of logistics transportation. The experimental results suggest that the application of the proposed method to the visual tracking of container logistics transportation can improve the accuracy of container tracking.

Published: May 2021

Based on the transmission characteristics of networks and the systematization of technical risks in national major science and technology projects, the risk transmission mechanism of national major science and technology projects is deeply discussed herein. Firstly, the system of systems (SoS) engineering process model of national major science and technology projects is constructed, including two levels and three stages. Secondly, the hierarchical structure of national major science and technology projects is analyzed, and the risks are divided into different levels, such as SoS, system, subsystem, equipment, module, and components. Finally, we describe the risk transfer mechanism using the forest-fire model and outline a risk control strategy. The results show that the findings are helpful for recognizing the essence and transmission mechanism of technical risks of national major science and technology projects and for reducing the risk from the source. The research results can be applied to project management in the transportation field.

Authors: Bai Lijie , Yuan Zhiming , Zhao Hongtao , Zhang Tao
Published: May 2021

This paper studies the real-time trains routing and platforming problem (RT-TRPP) in railway stations that arises from the unreliable arrival times of freight trains, flexible shunting operations and dynamic station layout caused by equipment failure. The feasibility of station timetable is checked before preparing a route for a train or after updating the station layout. If the station timetable is infeasible, the reassignment of trains is triggered. After introducing a problem formulation for the RT-TRPP, we propose an Integer Linear Program (ILP) that strives to minimize the number of conflicting trains. In resulting timetable, directions, arrival and leaving time remain the same with networks timetable to prevent traffic disturbance of neighboring territories. If the resulting timetable is still infeasible, conflicting trains are pointed out with the cause analysis. The method is tested on real-world complex station which receives always the overload of trains’ activities. The optimal full-day solution of 249 trains is obtained within 2 seconds. The efficiency of this method meets the time-critical nature of RT-TRPP.

Published: May 2021

In order to improve the efficiency of sentiment analysis of students in ideological and political classrooms, under the guidance of artificial intelligence ideas, this paper combines data mining and machine learning algorithms to improve and propose a method for quantifying the semantic ambiguity of sentiment words. Moreover, this paper designs different quantitative calculation methods of sentiment polarity intensity, and constructs video image sentiment recognition, text sentiment recognition, and speech sentiment recognition functional modules to obtain a combined sentiment recognition model. In addition, this article studies student emotions in ideological and political classrooms from the perspective of multimodal transfer learning, and optimizes the deep representation of images and texts and their corresponding deep networks through single-depth discriminative correlation analysis. Finally, this paper designs experiments to verify the model effect from two perspectives of single factor sentiment analysis and multi-factor sentiment analysis. The research results show that comprehensive analysis of multiple factors can effectively improve the effect of sentiment analysis of students in ideological and political classrooms, and enhance the effect of ideological and political classroom teaching.
Non-Motor Symptoms of Amyotrophic Lateral Sclerosis: A Multi-Faceted Disorder
Authors: Nash Yuval , Sitty Michal
Published: May 2021

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive degeneration of motor pathways. A growing body of evidence from recent years suggests that ALS results in a wide range of non-motor symptoms as well, which can have a significant impact on patients’ quality of life. These symptoms could also, in turn, provide useful information as biomarkers for disease progression, and can shed insight on ALS mechanisms. Here we aim to review a wide range of non-motor symptoms of ALS, with emphasis on their importance to research and clinical treatment of patients.

Authors: Damen Manon , Schijvenaars Mascha , Schimmel-Naber Marlies , Groothuismink Johanne , Coenen Marieke , Tieleman Alide
Published: May 2021

Background:

Myotonic dystrophy type 2 (DM2) is caused by a CCTG repeat expansion in intron 1 of the CCHC-Type Zinc Finger Nucleic Acid Binding Protein ( CNBP) gene. Previous studies indicated that this repeat expansion originates from separate founders.

Objective:

This study was set out to determine whether or not patients with DM2 originating from European and non-European countries carry the previously described European founder haplotypes.

Methods:

Haplotype analysis was performed in 59 DM2 patients from 29 unrelated families. Twenty-three families were from European descent and 6 families originated from non-European countries (India, Suriname and Morocco). Seven short tandem repeats (CL3N122, CL3N99, CL3N59, CL3N117, CL3N119, CL3N19 and CL3N23) and 4 single nucleotide polymorphisms (SNP) (rs1871922, rs1384313, rs4303883 and CGAP_886192) in and around the CNBP gene were used to construct patients’ haplotypes. These haplotypes were compared to the known DM2 haplotypes to determine the ancestral origin of the CNBP repeat expansion.

Results:

Of 41 patients, the haplotype could be assigned to the previously described Caucasian haplotypes. Three patients from Morocco and Portugal had a haplotype identical to the earlier reported Moroccan haplotype. Twelve patients from India and Suriname, however, carried a haplotype that seems distinct from the previously reported haplotypes. Three individuals could not be assigned to a specific haplotype.

Conclusion:

The ancestral origin of DM2 in India might be distinct from the Caucasian families and the solely described Japanese patient. However, we were unable to establish this firmly due to the limited genetic variation in the region surrounding the CNBP gene.

Background: Parkinson’s disease (PD) is a progressive neurological disorder where loss of dopamine neurons in the substantia nigra and dopamine depletion in the striatum cause characteristic motor symptoms. Currently, no treatment is able to halt the progression of PD. Glial cell line-derived neurotrophic factor (GDNF) rescues degenerating dopamine neurons both in vitro and in animal models of PD. When tested in PD patients, however, the outcomes from intracranial GDNF infusion paradigms have been inconclusive, mainly due to poor pharmacokinetic properties. Objective: We have developed drug-like small molecules, named BT compounds that activate signaling through GDNF’s receptor, the transmembrane receptor tyrosine kinase RET, both in vitro and in vivo and are able to penetrate through the blood-brain barrier. Here we evaluated the properties of BT44, a second generation RET agonist, in immortalized cells, dopamine neurons and rat 6-hydroxydopamine model of PD. Methods: We used biochemical, immunohistochemical and behavioral methods to evaluate the effects of BT44 on dopamine system in vitro and in vivo. Results: BT44 selectively activated RET and intracellular pro-survival AKT and MAPK signaling pathways in immortalized cells. In primary midbrain dopamine neurons cultured in serum-deprived conditions, BT44 promoted the survival of the neurons derived from wild-type, but not from RET knockout mice. BT44 also protected cultured wild-type dopamine neurons from MPP+-induced toxicity. In a rat 6-hydroxydopamine model of PD, BT44 reduced motor imbalance and seemed to protect dopaminergic fibers in the striatum. Conclusion: BT44 holds potential for further development into a novel, possibly disease-modifying, therapy for PD.

Published: May 2021

Background: The relationship among neuroticism, smoking, and Parkinson’s disease (PD) is less examined. Objective: To examine the causal associations between neuroticism, smoking initiation, and the risk of PD. Methods: We performed a two-sample Mendelian randomization (MR) design in a network framework. Summary statistics from meta-analyses of genome-wide association studies (GWAS) were based on large cohorts of European ancestry. Study participants were from various cohort studies for neuroticism and smoking initiation, and case-control studies or cohort studies of PD from previously published GWAS meta-analyses. Patients with PD were ascertained from either clinical visit or self-reported. Results: The two-sample MR analysis showed no evidence for a causal association between neuroticism and PD risk (odds ratio [OR] 0.86, 95%confidence intervals [CIs] 0.67 to 1.12). While we did not find a significant association between neuroticism and PD, one SNP, rs58879558 (located in MAPT region), was associated with both neuroticism and PD. We found a significant association of neuroticism on smoking initiation (OR: 1.10, 95%CI: 1.05 to 1.14). Further, our results provided evidence for a protective effect of smoking initiation on the risk of PD (OR: 0.75, 95%CI: 0.62 to 0.91). Conclusion: These findings do not support a causal association of neuroticism on PD risk. However, they provide evidence for a causal relationship between neuroticism and smoking initiation and a strong causal effect of smoking initiation on a reduced risk of PD.

Authors: Dawson Shay , McCormick Bryan , Piatt Jennifer , Knapp Doug , Dickinson Stephanie
Published: May 2021

PURPOSE: Youth with physical disabilities are at an elevated risk for poor psychosocial health. Pediatric medical camps are one common intervention utilized to provide short-term psychosocial support. However, there is a growing criticism that the effects of such programs diminish as participants return to home and school settings post residential camp experience. A post camp support intervention, the first known in the literature, was tested for perceptions of mattering and self-esteem. Specifically, this study examined the psychosocial effect of a year-round mentoring and online support program as an adjunct to residential camp (intervention) as compared to peers that attended only the summer residential experience (comparison group). METHODS: A quasi-experimental design using an intervention and comparison group was implemented. Data were analyzed using a repeated measures analysis of variance to test for within group and between group effect. RESULTS: A small effect (partial η2= 0.096) between groups (p< 0.17) and a moderate effect (partial η2= 0.133) within groups (p< 0.10) was detected for the mattering construct. A positive effect for self-esteem was not detected between or within groups. CONCLUSIONS: The online and mentoring support program appeared to improve perceptions of mattering three months into implementation. Future implications center on the refinement of the support program and suggestions for further longitudinal research.

Published: May 2021

BACKGROUND: Little is known on the peripheral and central sensory contributions to persistent dizziness and imbalance following mild traumatic brain injury (mTBI). OBJECTIVE: To identify peripheral vestibular, central integrative, and oculomotor causes for chronic symptoms following mTBI. METHODS: Individuals with chronic mTBI symptoms and healthy controls (HC) completed a battery of oculomotor, peripheral vestibular and instrumented posturography evaluations and rated subjective symptoms on validated questionnaires. We defined abnormal oculomotor, peripheral vestibular, and central sensory integration for balance measures among mTBI participants as falling outside a 10-percentile cutoff determined from HC data. A X-squared test associated the proportion of normal and abnormal responses in each group. Partial Spearman’s rank correlations evaluated the relationships between chronic symptoms and measures of oculomotor, peripheral vestibular, and central function for balance control. RESULTS: The mTBI group (n = 58) had more abnormal measures of central sensory integration for balance than the HC (n = 61) group (mTBI: 41% –61%; HC: 10%, p’s < 0.001), but no differences on oculomotor and peripheral vestibular function (p > 0.113). Symptom severities were negatively correlated with central sensory integration for balance scores (p’s < 0.048). CONCLUSIONS: Ongoing balance complaints in people with chronic mTBI are explained more by central sensory integration dysfunction rather than peripheral vestibular or oculomotor dysfunction.
Minimizing formaldehyde exposure in a hospital pathology laboratory
Authors: d’Ettorre Gabriele , Caroli Anna , Mazzotta Mauro
Published: May 2021

BACKGROUND: The safety and health of healthcare workers employed in pathology laboratories and exposed to formaldehyde (FA) is a matter of concern worldwide, as several health effects have been observed in workers resulting from exposure to FA, both short and long-term. OBJECTIVE: The study was aimed to describe the strategy implemented in a hospital pathology laboratory to minimize workers’ exposure to FA through interventions to working environment and workforce. METHODS: The NIOSH 2016 method for detecting gaseous FA was adopted to perform personal and area active sampling of FA. The samples were subsequently analyzed by High Performance Liquid Chromatography. The exposure to FA was measured before and after improvement interventions. RESULTS: The pre-intervention step showed FA levels exceeding the threshold limit values (TLV) established by ACGIH, both the time-weighted average (TLV-TWA) and short term exposure limit (TLV-STEL); after the improvement interventions, the median concentrations of personal and area FA sampling were respectively of 0.025 ppm (Range = 0.023–0.027) and 0.023 ppm (Range = 0.022–0.028) and significantly lower than pre-intervention step (p < 0.05) and below the TLV-TWA and TLV-STEL established by ACGIH. CONCLUSIONS: In our study the workers’ involvement in the risk management of FA exposure together with engineering improvements revealed a strategic way to minimize the FA pollution in the studied laboratory. Healthcare companies should consider the need to ensure the workers’ participation in the management of occupational hazards, including FA, to reach the goal of healthy workplaces.

Bu çalışmanın amacı, okul müdürlerinin ve öğretmenlerin yıldırma davranışlarına yönelik algılarındaki benzerlikleri ve farklılıklarını ortaya koymaktır. Nitel araştırma desenlerinden fenomenoloji deseninin kullanıldığı çalışmada katılımcılar, 30 okul müdürü ve 30 öğretmenden oluşmaktadır. Yapılan görüşmelerle ulaşılan veriler, içerik analizi ile çözümlenmiştir. Araştırmasonuçlarında, okul müdürlerinin ve öğretmenlerin tamamının yıldırma kavramına yönelik bilgi sahibi oldukları, okul müdürlerinin ve öğretmenlerin okullarda yıldırma davranışlarıyla karşılaştıkları, bu durumu daha çok psikolojik baskı olarak ifade ettikleri ve okul müdürlerinin yıldırmayı genellikle çok yönlü bir süreç olarak; öğretmenlerinse daha çok amir kaynaklı bir süreç olarak algıladıkları ortaya koyulmuştur. Ayrıca, okul müdürleri ve öğretmenler yıldırmanın stres, öfke, huzursuzluk ve psikolojik sorunlar gibi bireye yönelik olumsuz etkilerinin olduğu ve mağdurların sessiz kalarak yıldırmaya boyun eğdiği konusunda ortak bir algıya sahiptir. Hem okul müdürleri hem de öğretmenler, yıldırma sürecine maruz kalan bir bireyi fark ettiklerinde sessiz kalmayacaklarına, yıldırma sürecine müdahil olacaklarına ve mağdurun yanında yer alacaklarına yönelik ortak bir algı ortaya koymuştur. Okul müdürlerine göre okullarda yaşanılan yıldırma davranışlarının en temel nedeni empati ve iletişim eksikliğiyken; öğretmenlerin birçoğuna göre ise liyakat eksikliğidir. Yıldırmanın kurumsal etkileri değerlendirilirken okul müdürleri daha çok kurum kimliği açısından; öğretmeler ise daha çok özel ve bireysel açıdan algılar ortaya koymuştur. Okul müdürlerinin çoğu, yıldırma karşısında hukuki yollara başvurmayı yıldırma ile mücadele stratejisi olarak görmekte; öğretmenlerin yarısı ise yıldırma karşısında kaçınma, görmezden gelme stratejisini izlemektedir. Araştırmanın sonunda yıldırma davranışlarının ve okul müdürlerinin ve öğretmenlerin algı farklarının okul ortamında azaltılmasına yönelik öneriler sunulmuştur.
Acquisitive Desire in Early Childhood: Rethinking Rivalry in the Playroom
Authors: Ross Suzanne
Published: May 2021

What if we could observe the normal operation of mimetic desire in a rivalry-free environment? What would object relationships look like? Would acquisitive desire make an appearance without the encouragement of the model-obstacle dynamic? Montessori’s teacher training method offers a rigorous approach to removing rivalry from the student-teacher relationship. It is designed and functions to prevent the model-obstacle phenomenon from occurring. Therefore it provides us with a laboratory for observing mimetic desire in as close to a pre-lapsarian state as we can approximate this side of the gates of Eden.
Assessment of multi-dimensional poverty in Quang Ngai province
Authors: Huỳnh Phát Đinh
Published: May 2021

According to the multidimensional poverty line applied for the period 2016 - 2020, the quality of life of impoverished people in Quang Ngai province was dramatically low, forcing residents to face up to a serious shortage of basic social needs. Poverty in terms of their income was the main factor in the poverty structure of Quang Ngai province (generally over 90% of the total poor households). By 2020, the number of poor households who missed the criteria of hygienic toilets was the highest, accounting for 59.59% of the total number of poor households. The figures for the inaccessibility of the marginalized to basic needs were disproportionately high, with 40.64% people lacking telecommunications services such as telephones or the Internet, 40.59% using unhygienic water sources, 35.09% having a housing area per capita of less than 8 square meters and 33.53% living in temporary houses. The indicator with the least deficiency rate was the children’s schooling status and access to health services. However, the number of households whose members did not possess health insurance was extremely high, which might potentially bear the risk of households falling back into the poverty status when a member of the family gets a disease. Changes in multidimensional poverty show that although urban areas have a high rate of people escaping from poverty, the rate of households falling back to poverty status is also higher than that of rural areas; The rate of households falling into poverty in rural areas is much higher than that in urban areas. The Covid 19 pandemic and natural disasters which occurred in 2020 also significantly contributed to increasing the number of poor households. In order to reduce poverty and improve people's capacity to access basic social services, Quang Ngai province needs to pay attention to creating livelihoods, promoting the achievements of education universalization and the health insurance system, and improving the efficiency of investment in infrastructure on the basis of integrating the Target Programs.

A Study of Nones in Brazil and the USA in Light of Secularization Theory with Missiological Implications
Authors:   , chavez jolive
Published: May 2021

The growth of those who declare themselves to be Nones, or religiously unaffiliated, in Brazil and the USA has been continuously higher than that of the general population. In Brazil, they are the third-largest group in the religious field, behind only Catholics, and Pentecostal evangelicals. In the USA, they are the second largest group, after Protestants as a whole. The Nones, in their diverse groups, are more represented among the youth in both cultures, and reflect the modern and postmodern influences of contemporary secularism, being a product of the process of changing human thought. This work studies the Nones, in both countries, based on selected elements that characterize the theories of secularization used within the sociology of religion. In the absence of a direct biblical text related to the Nones, as they are a phenomenon much later than the biblical period, a suggested biblical framework for mission with the group was chosen based on biblical narratives describing the missio Dei among what the Bible calls foreigners. In the fifth chapter, the study proposes eight areas considered sensitive for the missional relationship with the Nones in both Brazil and America: The Identity of God, The Bible as the Source of Truth, Institutionalized Religion, Need for Relationships and Community, The Social Role of Religion, Cross-Cultural Barriers, Cultural and Religious Plurality, and Mass Communication/Technology. Some of these can be considered critical, and others as an opportunity for mission. The characteristics of Nones related to each area were presented, and then, missiological and sociological principles were suggested to fill the gaps in the respective areas, forming a bridge of contact with the Nones.

Стаття присвячена актуальним питанням визначення закономірностей розвитку вітчизняного фондового ринку. В складних умовах становлення український фондовий ринок не встиг стати ефективним механізмом для здійснення обігу фінансових активів. Це значно гальмує розвиток економіки в цілому, а також підриває довіру міжнародного суспільства до положення держави в світі, оскільки чесна торгівля на біржі є показником всебічного рівня розвитку держави. Через відсутність дієвого шляху для розподілу ресурсів відбувається їх нераціональне накопичення, зростає тіньовий сектор, відбувається зниження рівня розвитку усіх сфер діяльності людини. У статті проаналізовано тенденції розвитку ринку методами вейвлет-перетворень, визначено закономірності, що є основними в його функціонуванні. В подальших дослідженнях і при врахуванні більшої кількості можливих чинників, що можуть вплинути на зміну торгівлі, та аналізу процесів, що відбуваються на фондовому ринку, можна розробити більш якісну оцінку українського фондового ринку та залучити усі можливості для його стабільної діяльності і розвитку.
