The Legal Dimension of the Relation Between the Chinese Communist Party and the Private Economy. A Perspective of the Article 19 of the Company Law
Authors: Sabatino Gianmatteo
Published: August 2021

Chinese economic development has been driven, among other factors, by the gradual expansion of the private economy and the establishment of Chinese-based multinational corporations recognized as “champions” of the Chinese economy. At the same time, the Chinese Communist Party strives to maintain proper coordination mechanisms over the Chinese private economy, in order to ensure the harmonization between private and public interests. Does such policy direction, pursued by the Chinese leadership, rely on legal mechanisms? Does the Chinese Communist Party have legal instruments at its disposal in order to carry out coordinative functions concerning the private economy? The issue, although acknowledged by several scholars, has been rarely the object of a comprehensive legal analysis, taking into account the interactions between the different legal formants of the Chinese system. The purpose of this paper is to sketch an outline of the main legal mechanisms empowering the Chinese Communist Party to supervise and coordinate the activity of private economic operators. Starting from the assessment of some recent developments, embodied in «Opinions on Strengthening the United Front Work in the Private Economy in the New Era» issued in September 2020, the analysis will try to identify some of the most relevant legal provisions aimed at ensuring Party supervision over the private economy, in particular Art. 19 of the Company Law. Such provisions will be analyzed not only within the context of the recent developments of Chinese economic law, but also with regard to its practical applications by courts, in order to define the scope, in concrete, of Party activities in the private economy. The information gathered and analyzed will then be taken as conceptual basis to draw some conclusions regarding the structural role of the Chinese Communist Party in the development of Chinese commercial and economic law.

Published: August 2021

Wood properties of furfurylation can be altered by reaction mechanisms of furfuryl alcohol polymer (PFA) and cell walls. Although chemical reactions between PFA and lignin have been studied, reaction mechanisms between PFA and cell wall components, including lignin, cellulose and hemicellulose are still not comprehensively understood. In order to elucidate chemical reactions regarding PFA with wood cell walls, model compounds of main cell wall components were used to investigate its reactions with PFA by 13C NMR spectroscopy and differential scanning calorimetry (DSC). Results showed that there was no chemical bonding of PFA with either cellulose or hemicellulose. Condensations of uncrowded ring positions (meta, ortho and para) and side chains (α–C, β–C, β–OH, and γ–OH) of lignin with PFA did occur based on 13C NMR spectra. Reaction enthalpy and activation energy also confirmed the condensation reactions between lignin and PFA. This study could provide design guidelines to control the chemical reactions of PFA in cell walls and lignin and, therefore, improve the properties of furfurylated wood.

Published: August 2021

As the exhaust rate of the conventional sources has geared up already, this is compelling the power industries to install the power plants based on the non-conventional sources so that future demand of the energy supply can be fulfilled. Among the various sources of renewable energy like wind, hydro, tidal etc., solar energy is the most easily accessible and available renewable energy source. Ensuring the feasibility of any energy source not only technical but also the economical perspective is the most important criteria. This paper has incorporated both the perspective and has done the techno-economic analysis to determine the optimum combination of the PV array size and battery size to minimize the overall electricity generation per unit. In this paper, a standalone solar PV system has been analyzed for the location of Jamshedpur, where an effort has been done to choose the optimum combination of the solar array and battery size within the desired range of LLP so that the electricity generation cost per unit can be minimized. The overall duration of the analysis has been done for a year and the outcome of the research has been verified with the help of MATLAB software.

Authors: Lüthen Holger , Schröder Carsten , Grabka Markus M. , Goebel Jan , Mika Tatjana , Brüggmann Daniel , Ellert Sebastian , Penz Hannah
Published: August 2021

The aim of the project SOEP-RV is to link data from participants in the German Socio-Economic Panel (SOEP) survey to their individual Deutsche Rentenversicherung (German Pension Insurance) records. For all SOEP respondents who give explicit consent to record linkage, SOEP-RV creates a linked dataset that combines the comprehensive multi-topic SOEP data with detailed cross-sectional and longitudinal data on social security pension records covering the individual’s entire insurance history. This article provides an overview of the record linkage project, highlights potentials for analysis of the linked data, compares key SOEP and pension insurance variables, and suggests a re-weighting procedure that corrects for selectivity. It concludes with details on the process of obtaining the data for scientific use.
Analytic integration of the Newton potential over cuboids and an application to fast multipole methods
Authors: Kirchhart Matthias , Weniger Donat
Published: August 2021

We present simplified formulae for the analytic integration of the Newton potential of polynomials over boxes in two- and three-dimensional space. These are implemented in an easy-to-use C++ library that allows computations in arbitrary precision arithmetic which is also documented here. We describe how these results can be combined with fast multipole methods to evaluate the Newton potential of more general, non-polynomial densities.

Published: August 2021

Objectives

Worldwide, the overall cesarean section is rising. Trial of labor after cesarean (TOLAC) is an overall safe option with an immediate impact on neonatal and maternal short- and long-term health. Since the use of prostaglandins in cervical ripening is associated with an increased risk of uterine rupture, mechanical methods as balloon catheters or osmotic dilators have been suggested for cervical ripening prior to induction of labour. Here we are analyzing and comparing the VBAC rate, as well as maternal and fetal outcome in cervical ripening prior to TOLAC.

Methods

This prospective dual center study analyses maternal and neonatal outcomes of TOLAC in women with an unfavorable cervix requiring cervical ripening agent. The prospective application of an osmotic dilator (Dilapan-S, n=104) was analysed in comparison to the retrospective application of off-label dinoprostone (n=102).

Results

The overall fetal and neonatal outcome revealed no significant differences in both groups. Patients receiving cervical ripening with the osmotic dilator delivered vaginally/by ventouse in 52% of cases, compared to 53% when using dinoprostone (p=0.603). The interval between application to onset of labor was significantly higher in the osmotic dilator group (37.9 vs.20.7 h, p=<0.001). However, time from onset of labor to delivery was similar in both groups (7.93 vs. 7.44 h, p=0.758). There was one case of uterine rupture in the dinoprostone group.

Conclusions

Our data shows that the application of the osmotic dilator leads to similar outcomes in VBAC rate and time from onset of labor to delivery as well as safety in both groups compared to off-label use dinoprostone. Cervical ripening using the mechanical dilator is a viable and effective option, without the risk of uterine hyperstimulation.
Residuation in finite posets
Authors: Chajda Ivan , Länger Helmut
Published: August 2021

When an algebraic logic based on a poset instead of a lattice is investigated then there is a natural problem how to introduce implication to be everywhere defined and satisfying (left) adjointness with conjunction. We have already studied this problem for the logic of quantum mechanics which is based on an orthomodular poset or the logic of quantum effects based on a so-called effect algebra which is only partial and need not be lattice-ordered. For this, we introduced the so-called operator residuation where the values of implication and conjunction need not be elements of the underlying poset, but only certain subsets of it. However, this approach can be generalized for posets satisfying more general conditions. If these posets are even finite, we can focus on maximal or minimal elements of the corresponding subsets and the formulas for the mentioned operators can be essentially simplified. This is shown in the present paper where all theorems are explained by corresponding examples.

An existence level for the residual sum of squares of the power-law regression with an unknown location parameter
Authors: Jukić Dragan , Marošević Tomislav
Published: August 2021

In a recent paper [JUKIĆ, D.: A necessary and sufficient criterion for the existence of the global minima of a continuous lower bounded function on a noncompact set, J. Comput. Appl. Math. 375 (2020)], a new existence level was introduced and then was used to obtain a necessary and sufficient criterion for the existence of the global minima of a continuous lower bounded function on a noncompact set. In this paper, we determined that existence level for the residual sum of squares of the power-law regression with an unknown location parameter, and so we obtained a necessary and sufficient condition which guarantee the existence of the least squares estimate.

Nanotechnology-enabled biomedical engineering: Current trends, future scopes, and perspectives
Authors: Ray Shariqsrijon Sinha , Bandyopadhyay Jayita
Published: August 2021

Applications of nanotechnology in biomedical engineering are vast and span several interdisciplinary areas of nanomedicine, diagnostics, and nanotheranostics. Herein, we provide a brief perspective on nanotechnology as an enabling tool for the design of new functional materials and devices for medical applications. Semiconductor nanocrystals, also known as quantum dots, are commonly used in optical imaging to diagnose diseases such as cancer. Varieties of metal and metal oxide nanoparticles, and two-dimensional carbon-based nanostructures, are prospective therapeutics and may also be used in protective antiviral/antibacterial applications. Similarly, a number of nanomaterials have shown the potential to overcome the drawbacks of conventional antiviral drugs. However, assessing the adverse effects and toxicities of nanoparticles in medicine and therapeutics is becoming more critical. This article discusses the latest developments of nanomaterials in diagnosis, nanotheranostics, and nanomedicines, with particular emphasis on the importance of nanomaterials in fighting against coronavirus disease. Further, we considered the safety and toxicity of nanomaterials in the context of biomedical applications. Finally, we provided our perspective on the future of nanotechnology in emerging biomedical engineering fields.
Disruption, Preference Cascades, Contagion, and the Transition to Agriculture in Northern Europe
Authors: Bogucki Peter
Published: August 2021

The transition to agriculture in northern Europe around 4000 BC presents an unresolved question. Explanations have vacillated between the adoption of Neolithic things and practices by indigenous foragers to the displacement of Mesolithic populations by immigrant farmers. The goal of this article is to articulate some thoughts on this process. First, it would have been necessary to introduce food production practices, by acculturation or immigration, to disrupt not only the forager economy but also their values of sharing and social relations. The use of milk for dairy products is a prime candidate for such a disruptive technology. The attraction of Neolithic ways may have been initially concealed from others, and only the realization of their widespread appeal caused fellow foragers to change their preferences. Second, it was necessary for foragers to commit to these changes and for the changed values to spread through mechanisms of social contagion. Immigrant farmers may have been especially influential in this regard, with increased sedentism and interaction being catalysts for completing the transition to agriculture.
The influence of piperazine diamine templates on the synthesis, structures and properties of uranyl oxalate complex
Authors: Zou Yaxuan , Qiao Xueling , Su Yin , He Jiangang
Published: August 2021

As an important nuclear material, uranium is one of the most concerned elements in the nuclear fuel cycle, which could interact with many inorganic and organic ligands. Amine templates have a significant structural-oriented effect on the construction of uranyl oxalate complex. In this work, the piperazine diamine templates were used to synthesize uranyl oxalate complex and their crystal structures were resolved by single crystal diffraction, and their spectra were studied by IR, Raman, UV–vis, fluorescence, and EPR techniques. The final results show that crystal structures, properties and applications of uranyl oxalate complex have a close correlation with polyamine templates. The single crystal structure results show that the structural-oriented effect of piperazine diamine template is greatly affected by the proportion and concentration of solute in the surrounding environment. And the alkyl substituents on N atoms of amine templates are related to the tight of structures. Interestingly, 5# has a potential application as the original material for multiple reuse of fluorescent sensor materials. At present, there is no clear and in-depth study on the internal mechanism of such phenomena in solid uranyl complexes, and the specific mechanism needs to be further explored.
Stability of proteins involved in initiation of DNA replication in UV damaged human cells
Authors: Anachkova Boyka Borisova , Djeliova Vera Lyubchova
Published: August 2021

The protein stability of the initiation factors Orc2, Orc3, Orc4, and Cdc6 was analyzed after UV light exposure in two human cell lines. In the cell line with higher repair capacity, HEK 293, no changes in the cell cycle distribution or in the protein levels of the investigated factors were detected. In HeLa cells that are characterized by lower repair capacity, UV irradiation caused a reduction of the levels of Cdc6, Orc2 and Orc3, but not of Orc4 or triggered apoptosis. The appearance of the truncated 49 kDa form of Cdc6 suggested the involvement of the caspase pathway in the degradation of the proteins. Reduced protein levels of Cdc6 were detected in UV damaged HeLa cells in which the apoptotic process was blocked with the caspase inhibitor Z-VAD-fmk, indicating that the degradation of Cdc6 is mediated by the proteasome pathway instead. In the presence of caffeine, an inhibitor of the cell cycle checkpoint kinases, Cdc6 was stabilized, demonstrating that its degradation is controlled by the DNA damage cell cycle checkpoint. We conclude that in response to DNA damage, the activation of origins of replication can be prevented by the degradation of Cdc6, most likely through the proteasome pathway.

Authors: GÜNEŞ Erkan , AYDIN Furkan , ÇAKIR İbrahim
Published: August 2021

This study aims to identify yeasts from spontaneously fermented herbs used for Van herby cheese and to evaluate their enzymatic activities. Sequencing of partial 26S rRNA gene revealed the species of Pichia membranifaciens (n = 8), Kazachstania servazzii (n = 6), Debaryomyces hansenii (n = 2), Kluyveromyces marxianus (n = 2), and Pichia fermentans (n = 2). Enzyme profiles were determined using API-ZYM strips. The isolates had diverse enzyme activities, including alkaline and acid phosphatase, esterase, esterase lipase, aminopeptidases, and proteases mostly at different levels, which may have crucial roles during ripening of the cheese. K. marxianus M8.1, D. hansenii M6.1, and M6.3, P. membraniciens M13.1, M13.2, and M14.1 had superior and diverse enzymatic characteristics. Such enzymatic activities could be of great technological importance for the determination of adjunct culture along with starter lactic acid bacteria for the production of Van herby cheese.
From Cape Verde to Newport
Authors: de Bruin Karen
Published: August 2021

This Report from the Field is a post-mortem reflection on a statewide memorialization project on slavery that ultimately failed. In this essay, I attribute the failure of the project in large part to conflicting historical approaches and claims to narrative authority over the representation of a specifically Rhode Island image of slavery. Although the organization studied here no longer exists, other nascent grassroots organizations dedicated to the memorialization of slavery and grappling with issues of emerging narratives and competing claims to local memory may derive benefit from my analysis and the proposed “scaffolded conversations” with which I conclude.
Memorializing Dinah and Reckoning with Enslavement
Authors: Uzwiak Beth A.
Published: August 2021

Inequality in Bronze is a two-year project (2018–20) reckoning with the history of slavery at Stenton, a plantation house museum in Philadelphia, by commissioning a new memorial to Dinah, a woman enslaved at the property in the mid-1700s. Drawing on data collected throughout the project, this article argues that historic house museums need to move from “community participation” to “community integration” in their efforts to forefront racial equity. This article asks how we can redress centuries of erasure and the absence of Black lives at historic sites. It offers points of consideration for other historic house museums contemplating similar projects as the collective work to address the legacies of American enslavement continues.

To study the current situation of existing middle school students' self-management and its application to provide a reference for further optimizing the self-management strategy of middle school students, exerting the value of self-management of students, and cultivating the self-management ability of middle school students.
Prediction of the color variation of moso bamboo during CO2 laser thermal modification
Authors: Li Rongrong , Chen Jingjing , Wang Xiaodong Alice
Published: August 2021

Thermal modification is widely used for bamboo materials as an efficient modification method. CO2 laser with the advantages of high energy density, short process period, non-pollution, etc. could be applied as a novel thermal treatment for wooden and bamboo materials processing. The laser intensity argumentation of power, motion arguments of feed rate, and sweep width for laser emitter were selected as input arguments for treating the Moso bamboo surface. The lightness variation and total color variation (∆L* and ∆E*) were collected using a portable colorimeter to describe the bamboo surface color variation after laser irradiation. Response surface methodology was chosen for designing experiments and modeling. The results showed that the increase of laser power had a positive influence on increasing the absolute values of ∆L* and ∆E*, but the feed rate of laser emitter and sweep width increasing had opposite effects on absolute values of ∆L* and ∆E*. The quadratic models of ∆L* and ∆E* created by response surface methodology were competent for describing the relationship between laser processing arguments and color indexes of ∆L* and ∆E*. This approach will be useful for selecting suitable and desirable processing arguments to get the surface color of bamboo productions.
The analysis of the phenomenon of reflexivity in psychotherapy supervision: A systematic literature review
Authors: Vaštakė Marija , Skruibis Paulius
Published: August 2021

Reflexivity is a concept that is increasingly gaining prevalence in the literature of professional practice and it has been defined in a variety of ways; however, the differences in definition largerly depend on the context. Therefore, reflexivity development is the main goal of supervision; it is a powerful instrument that can impede the psychotherapist’s connection with his client, but there is no answer on what specifically enhances or decreases reflexivity during the supervision process. In the scientific articles analyzing supervision, there is no clear definition of the phenomenon of reflexivity and there is also a lack of empirical studies of reflexivity in supervision. The aim of this paper is to present our own definition and theoretical model of reflexivity in the psychotherapy supervision process as well as distinguish reflexivity between adjacent concepts like “reflection,” “self-reflection,” and “self-reflexivity.” We carried out a systematic review of literature within three databases and created a theoretical model of reflexivity in psychotherapy supervision. We also discuss the guidelines and methods for further empirical investigations of this phenomenon in psychotherapy supervision.

Market Innovation and Competitive Advantage of Telecommunication Companies in Kenya
Authors: Mugo Peter , Macharia Jimmy
Published: August 2021

Research question. To survive, organizations must have a competitive advantage in order to stay ahead of the competition. Market innovation has remained the driving force behind most market expansions and stability in the turbulent nature of global economies. The research question for the study thus was, “do market innovations influence the competitive advantage of telecommunication companies in Kenya?”

Design/Method/Approach. Using the philosophy of positivism, the study adopted an explanatory research design in testing the hypothesis. The main data collection instrument was a structured questionnaire using both physical conduct and online interactions to return 247 responses from mid and top-level managers in a total of 26 active telecommunications companies in Kenya. The study used both descriptive and inferential statistics using SPSS computer application to analyze the data.

Findings. The study findings established that innovative distribution channels significantly influenced the competitive advantage of telecommunication companies in Kenya, while advertising and promotions did not have a significant influence. This led to the conclusion that market innovation has a significant influence on the competitive advantage of telecommunication companies in Kenya.

Practical implications. The study recommends that telecommunication companies need to form collaborations and partnerships for establishing market distribution channels that have indicated to bring influence onto the competitive advantage of the companies. Other recommendations include a wider coverage of the East African market for the telecommunications sector. The study provides insights into new companies with an interest in the region.

Originality/Value. From the results, marketing and promotions are not the only major contributing factors in the competitive advantage of telecommunication companies in Kenya; one must consider distribution channels too.

Research limitations/Future Research. The study faced limitations on visiting the field during the COVID-19 pandemic period, thus encountering entry restrictions into various premises. All protocols were observed to overcome that obstacle. Some of the telecommunications companies were facing difficulties in operations and hence could not participate.

Multitud y resistencia en el marco del “imperio” contemporáneo, según Antonio Negri y Michael Hardt
Authors: Bonilla Elizondo Pablo
Published: August 2021

El presente artículo aborda las teorías desarrolladas por Antonio Negri y Michael Hardt sobre el imperio global contemporáneo, los nuevos sujetos políticos y las formas de resistencia que en él operan. Estas últimas, se presentan de forma coherente con las transformaciones epistemológicas que ha sufrido el arte en las últimas décadas, las cuales han redefinido sus prácticas y sus formas de vinculación con lo político. Se concluye que la imbricación entre arte y activismo político –a diferencia de los acoples modernistas entre arte y política– permite vislumbrar el potencial y la relevancia del arte contemporáneo para la continua construcción y defensa de una sociedad democrática, solidaria y equitativa en el panorama actual.

Investigating the dielectric properties of barium titanate nanocomposites using transmission electron microscopy image processing
Authors: Ferro Gio , Ganjam Dithi , Gibson Maia , Partington Katie , Trikha Akshay , Wu Mandy , Domrzalski Jessica , Dato Albert , Monson Todd
Published: August 2021

Barium titanate (BTO) is a ferroelectric perovskite material used in energy storage applications because of its high dielectric constant. A previous study showed that the dielectric constant for BTO nanoparticles drastically increases to over 15,000 at a particle size of 70 nm. This result is highly contested, but its implications to energy storage motivated our investigation into the dielectric constants of BTO nanoparticles that are incorporated into a polymer matrix. We developed a novel method of using image processing techniques on transmission electron microscope images of BTO-polymer nanocomposites. Data on the positions, shapes, sizes, and orientations of BTO nanoparticles were used to build more realistic computational models that simulate the dielectric behavior of the nanocomposites. Here, we investigate the relationship between regions of enhanced electric field and the composite dielectric constant.

This study aimed to determine the optimum water volume in certain growth media to optimize the growth and yield. The study used a 4 x 3 split plot design with three replications. The main plots were volume of drip irrigations i.e 600 ml day-1 tan-1, 1200 ml day-1 tan-1, 1800 ml day-1 tan-1, and 2400 ml day-1 tan-1 while the sub plots were growing media with three levels i.e soil + husk charcoal, soil + cocopeat, and soil + bokashi. The observed parameters  were plant  height,  leaf number, total plant root length, leaf area, leaf relative water content, proline, stomatal opening width, stomata density, chlorophyll content, flowering age, wet plant weight, dry plant weight, fruit weight, fruit circle, fruit brix, the fruit water content, and NPK content in leaf tissue. The water volume of 600 ml day-1 tan-1 is optimum with growing media soil + bokashi on fresh plant weight (1083.33 g) while the water volume of 1200 ml day-1 tan-1 with soil + bokhasi growing media had an effect on dry plant weight (95.80 g).The types of growing media have different water volume capacities for optimal plant growth and yields.
Effect of A20 on glucose dependent cell migration in acute lymphoblastic leukemia
Authors: Xuân Nguyen Thi , Chung Dang Thanh , Mao Can Van
Published: August 2021

Acute lymphoblastic leukemia (ALL) is the most common pediatric hematologic malignancy characterized by aberrant proliferation of immature lymphoid cells. A20 is a deubiquitinase gene that inhibits functional activation of immune cells mediated through nuclear factor κB (NFκB)/signal transducers and activators of transcription (STAT) pathways. A20 is frequently inactivated in leukemia/lymphoma. Little is known about the involvement between A20 and STAT signalling in regulating the function of ALL blasts. The present study, therefore, explored whether migration and apoptosis of peripheral blood mononuclear cells (PBMCs) and ALL blasts in high glucose conditions is regulated by A20. To this end, ALL blasts from blood samples of fifteen patients and PBMCs from healthy individuals in the absence of A20 were examined. Gene expression profile was determined by quantitative RT-PCR, cell apoptosis by flow cytometry, and cell migration by a transwell migration assay. As a result, the expression of A20 was inactivated in ALL blasts. Cell migration, but not apoptosis of ALL-blasts was enhanced when the cells were exposed to high glucose and dependent on A20 expression, the effects were abolished by using Nifuroxazide, a STAT inhibitor. In conclusion, A20 inhibited glucose-induced migration of ALL blasts through the STAT pathway. The effect might contribute to poorer survival of ALL patients, who develop hyperglycemia during therapy.

Collagen type VI-related disorders consist of Ullrich congenital muscular dystrophies (UCMD) and Bethlem myopathy, in which these entities are at two opposite extremes of the phenotype continuum. Clinical characteristics include proximal joint contracture, distal joint hyperlaxity, generalized muscle weakness, normal cognitive function, and pulmonary insufficiency. Affected individuals have trouble standing up and walking independently. Mutations in 3 genes (COL6A1, COL6A2, and COL6A3) are associated with decreasing collagen-VI production and disrupting the microfibrillar network between skeletal muscles. In the present study, using whole-exome sequencing (WES), a pathogenic variant in the COL6A1 gene (NM_001848, c.868G>C, p.G290R) was detected in a Vietnamese family with UCMD patients. Segregation analysis by Sanger sequencing confirmed that this mutation was inherited in an autosomal dominant pattern. This study expands the breadth of congenital muscular dystrophies research landcape and underscores the efficiency of WES in investigating the etiology of this group of heterogeneous diseases. Insight about the underlying genetic causes could contribute to develop a well-timed treatment regimen and help patients make an informed decision about reproductive health.
الذات في شعر حمد حمود الدوخي (مجموعة الأسماء كلّها أنموذجاً)

يعد الأدب وسيلة تظهر من خلالها الذات الشاعرة والمبدعة، لتكشف لنا عالمها العميق الغامض، وما يحويه من رؤى وتطلعات وأفكار، وما يحيط به من ظروف وتحولات. فالإبداع الأدبي ما هو إلا استجابة لما تريد الذات الإفصاح عنه، وفق مدركات نفسية ودوافع داخلية، تعجّ بها ذات المبدع المنصهرة في إبداعه، لتعبّر به عن نفسها. وهي حينما تفعل ذلك توطّد صلتها بالآخر/ المتلقي، وترسم له حدود العلاقة بالكون والحياة. فالذات عنصر مرن تتغير أيديولوجيتها، بتغير مكامن الظروف والأحوال المؤثرة في شخصية الأديب/ المنشئ، فتتأثر بالأحداث في شتّى أوجه الحياة السياسيّة والاجتماعيّة والاقتصاديّة، فالأديب ليس بمعزل عنها، وإنما متعايش مع دقائق تفصيلاتها البسيطة، فوضع لنفسه منهاجًا للتعبير عن ذاته. يعدّ الشعر تعبيرًا عن الوجدان الخالص؛ أي تعبيرًا عن ذات الشاعر، فتولدت منها المعاني التي التصقت بالذات، فانتشر الحزن، والإحباط، والانكسار، والإحساس بالغربة، كما برزت معاني الثورة والرفض وغيرها من الاتجاهات. لذا جاء البحث تحت عنوان ( الذات في شعر حمد الدوخي، مجموعة الأسماء كلها-أنموذجاً) للكشف عن أبرز مظاهر الذات وتجلياتها في مجموعة (الأسماء كلها) . الكلمات المفتاحيّة: الذات، حمد الوخي، الأسماء كلّها، النفسيّ، المكانيّ.

Authors: Brandão Thaynara Lays Sales , Silva Júlia Carolina Lopes , Francelino Jakeline Olindina
Published: August 2021

Objetivo: Avaliar o uso da suplementação de probióticos e prebióticos em crianças autistas. Fonte de dados: Foram identificados artigos nas bases de dados PubMed e SciELO. Para a localização dos estudos foram utilizados descritores em inglês cadastrados no Descritores em Ciências da Saúde (DeCS): Prebiotics. Probiotics. Autism Spectrum Disorder. Gut microbiota. Bifidobacterium. A busca limitou-se a artigos em inglês e compreendeu os anos de publicação entre 2015-2021. Síntese de dados: Um total de 6 ensaios clínicos realizados em crianças com autismo foram revisados sistematicamente. Com relação aos tipos de suplementações utilizadas foram 3 estudos que utilizaram probióticos, 2 que utilizaram prebióticos e probióticos e 1 que fez apenas o uso de prebióticos.  Apesar da quantidade escassa de estudos, os mesmos tiveram resultados notáveis com relação à suplementação de probióticos e prebióticos em crianças com Transtorno do Espectro Autista. Em alguns estudos foi possível observar a melhora na gravidade do autismo e melhorias com relação ao comportamento antissocial, já em outros houve o aumento de bactérias benéficas e diminuição das patogênicas no trato gastrintestinal levando a melhora de sintomas gastrointestinais recorrentes. Conclusões: É perceptível que o uso de prébióticos e probióticos pode promover diversos benefícios para os portadores de autismo, porém são necessários estudos com um número maior de indivíduos e havendo padrões quanto aos regimes de intervenção.
