Disrupting Patriarchal Perceptions of Single-Mother Families: An Analysis of Adolescent Narratives
Authors: Jacobs Carmelita , Andrews Grant
Published: April 2021

Parental educational support plays a significant role in the educational success of learners. Research has emphasised the important role of father involvement in educational achievement; however, little is known about how educational support is understood within marginalised contexts such as female-headed households, especially where fathers are absent or largely uninvolved in the lives of children. This article presents the perspectives of six adolescents in a South African community who reflect on what father involvement means to them in relation to educational support. Semi-structured interviews and a focus group were conducted with the participants to discuss their experiences. We use feminist theory to highlight the informal and non-traditional forms of support that are present in these female-headed households. The data were analysed by means of thematic content analysis. The findings revealed that all the adolescents had complex and deeply personal perspectives on the role a father could play in their lives, and that these views often contrasted with dominant stereotypes of female-headed households as inherently inferior. Although all the adolescents showed a desire for a relationship with a biological father, in some cases the influence of a father was framed as detrimental to the family unit and the educational success of the adolescents. These findings have implications for how schools and educational stakeholders can understand and engage with adolescents and families in female-headed households.

In this evolving Commentary Section, our coverage will span a diversity of opinions, ranging from robust critiques of education theories, policies and practices, to equally robust defences of the status quo—both internationally and locally. While Education as Change is committed to the human right to disagree, and while reason and rationality are often regarded as pillars of academic debate and discussion, these pillars of academic freedom and exploration are not to be confused with the contested and indeed liberal notion of “objectivity”.
Establishing the Link between the State of the Psychological Contract and Emotional Intelligence
Authors: Goudriaan Clarise , Linde Bennie
Published: April 2021

The objectives of this article were to determine whether a relationship exists between the state of the psychological contract and emotional intelligence, and whether emotional intelligence is a predicting variance of the state of the psychological contract. A sample of 224 individuals from the mining and engineering field was used. Two questionnaires were combined, namely, the questionnaire on psychological contracts across employment situations and the Schutte Self-report Emotional Intelligence Test. The Statistical Package for the Social Sciences was used to analyse the descriptive statistics and structural equation modelling to analyse the predictive statistics in order to develop a structural model. The results indicated a link between the two constructs, and that emotional intelligence is a predictor of the state of the psychological contract.

Towards the Directed Evolution of Artificial Metalloenzymes
Authors: Vallapurackal Jaicy
Published: April 2021

Artificial metalloenzymes (ArMs) are a class of enzymes holding great promise. In contrast to natural enzymes, the core of ArMs is a synthetic metallocofactor, with potential for bio-orthogonal reactivity, incorporated within a host protein. Next to chemical optimization of the metallocofactor,
genetic optimization of the protein allows the further improvement of the ArM. Genetic optimization through directed evolution requires extensive screening of a large sequence-scape to enable the optimization of a desired phenotype. The process is however mostly limited by the throughput of
the tools and methods available for screening. In recent years, versatile methods based on droplet microfluidics have been developed to address the need for higher throughput. This article aims to give an introduction into ArMs and the recent technological developments allowing high-throughput
directed evolution of enzymes.
Listening with Curiosity – Tracking the Acoustic Response of Portable Laser Ablation
Authors: Kradolfer Stefan , Heutschi Kurt , Koch Joachim , Günther Detlef
Published: April 2021

Nowadays, one of the methods of choice for minimal invasive sampling of solid matter is laser ablation (LA). Routine LA sampling is performed commonly in the laboratory and the amount of ablated mass can directly be monitored and analysed. By contrast laser-based sampling in the field,
using a portable laser ablation system (pLA), still remains challenging concerning low-absorbing or NIR-transparent samples. The current hardware is limited in regards to photon energy and density resulting in unsteady ablation. But as the actual amount of collected mass is the major crux
of on-site sampling, with this performance it is often unknown and estimates can only be made based on the experience from prior method development and the experience of the user. In the following work an easy-to-use method to monitor the amount of ablated material collected during laser-based
sampling by measuring the acoustic response is presented. The pLA-system was coupled to inductively coupled plasma mass spectrometry (ICPMS) via a diffusion driven gas exchange device (GED) which allowed to monitor mass removal and acoustic response quasi-simultaneously. For the current
instrumentation only actual mass removal leads to the formation of shockwaves (SW) and, thus, acoustic signals. These events can be used as indicator for executed LA events and counted on an individual basis. The intensity of acoustic signals has been shown to correlate with the LA mass, i.e.,
the amount of ablated material. This allows to perform re-adjustment of the laser focus during sampling for optimal ablation based on the intensity of the acoustic signal. Likewise, acoustic intensity together with counting allows the operator to make estimates about total mass sampled. Therefore,
unsuccessful laser aerosol collection in the field shall become a thing of the past.
The Nuclear Transport Protein Importin-5: A Promising Target in Oncology and Virology
Authors: Patouret Rémi
Published: April 2021

Cellular homeostasis importantly relies on the correct nucleoplasmic distribution of a large number of RNA molecules and proteins, which are shuttled by specialized transport receptors. The nuclear import receptor importin-5, also called IPO5, RanBP5 or karyopherin ?3, mediates
the translocation of proteins to the nucleus, and thus regulates critical signaling pathways and cellular functions. The normal function of IPO5 appears to be disrupted in cancer cells due to aberrant overexpression. IPO5 also demonstrated a pivotal role in viral replication. The constant
increasing number of publications shows an interest within the scientific community as a therapeutic target due to its pivotal role in protein trafficking.
China Economic Relations with Mauritania in the Age of the Belt and Road Initiative
Authors: Chaziza Mordechai
Published: April 2021

The People’s Republic of China (PRC) and the Islamic Republic of Mauritania have maintained steady bilateral relations since the establishment of diplomatic ties in 1965. This study examines China’s economic relations with the Islamic Republic of Mauritania in the Belt and Road Initiative era. Over the past years, the PRC has been increasing its presence and engagement with Mauritania’s economy and presenting itself as a reliable financial and investor partner. The main argument is that the PRC’s relationship with Mauritania is based on shared or mutual commercial interests, especially Mauritania’s economic development, industrialization, and social development through integration in the BRI framework. China has collaborated with Mauritania both bilaterally and multilaterally, mainly through the BRI framework, and is also expanding its political power and influence in the country at the expense of Western hegemony.

Introduction and Aim: Childhood overt hypothyroidism is a chronic disease that affect many system adversely and requires treatment. However, Subclinical Hypothyroidism (SH) ,defined obvious cases, impacts on other systems are unknown and there is no common approach to be treated. Moreover, SH may continue for many years, before they become overt hypothyroidism. Cardiovascular System (CVS) is one of the host system, which hypothyroidism adversely affects. Epicardial Adipose Tissue thickness (EAT) is known to be an important marker in terms of the cardiovascular risks. We aimed to determine the effects on CVS in children with SH. Material and Methods: The study included were 100 cases, which are 1-18 years had categorized in two groups; control group (50 children), who had no signs of thyroidal dysfunction and case group (50 children) who had diagnosed with SH, are recruited in the study. SH was diagnosed according to the slightly higher TSH than the upper limit (4.2M/L), normal free T4 and T3 levels. Medical Treatment (LT4) was decided according to the levels of TSH, sT3, sT4 and clinical status. EAT was determined by transthoracic echocardiographic measurements in millimeters. The SH cases were classified into two groups in terms of medical treatment. EAT thickness was measured in patients with treated group (SH1) and non-treated group (SH2) at admission (EAT0) and at 6. months (EAT 6). Results: Epicardial adipose tissue thickness was significantly higher in SH children, than the children without thyroid dysfunction. The mean value of the EAT in control group was 2,11 ± 0,52mm. Mean of EAT0 was 4,08 ± 1,41 in group SH1, mean of EAT0 was 4,31 ± 1,09mm in group SH2. In addition, mean of EAT6 was 3.65 ± 1,27mm in group SH1 and mean of EAT6 was 4,16 ± 1,10 in group SH2. Although there were a decrease in both group SH1 and SH2, at EAT6 compared to the EAT0, and this decrease was more significant in group SH1. Discussion: This study suggests that subclinical hypothyroidism effects adversly the cardiovascular system in children before hypothyroidism become overt. In future this data may be marker at the begining of LT4 treatment in children with SH.

The sole objective of this paper is to investigate Simulation and Optimization process for the production of polyethylene terephthalate, the biggest polymer being consumed all over the world. In this way, two polymerization reactors are replaced with one polymerization reactor. In this way equipment and operating and many other cost was reduced. Discussion has also been made on the optimum temperature and pressure along with most suitable catalyst. The objective function for the polymerization reactor is to maximize the production as well as conversion. It is found that the reactor should be operated at a high temperature initially to obtain high conversion of Dimethyl Terephthalate (DMT) first, but then it should be lowered to reduce the formation of side products. Previous work was done on Simulation for the batch reactor only but in this work the Simulation was applied to the continuous polymerization reactor and results is investigated.

Published: April 2021

Background: HIV-infected pregnant and breastfeeding adolescents are a particularly vulnerable group that require special attention and enhanced support to achieve optimal maternal and infant outcomes. Aim: To find out the prevalence of pregnancy in adolescent living with HIV, review evidence about Antenatal Care (ANC) service delivery and outcomes for HIV-infected pregnant adolescents in Muhoroni Sub County. Setting: The project was conducted in Muhoroni Sub County, Kisumu County, Kenya Method: Questionnaire was used on the total 98 girls who were on care at the Referral center containing the adolescents’ center which was Masogo subcounty hospital and Muhoroni County Hospital within the sub-county to obtained the results. Result: Of the 98 girls 25 (25.5%) hard pregnancy history in which 10 (10.2%) hard knowledge on PMTCT, while only 4 (4.1%) were having knowledge on PNS and lastly all the pregnant girls were having knowledge on both ANC and Drug adherence and only 10 (10.2%) pregnancy were planned while 15 (15.3%) were unplanned in which 10 (10.2%) pregnancy were aborted and 11 (11.2%) were delivered safely while 4 (4.1%) of the girls were currently pregnant. Conclusion: Reasons for the poor outcome among adolescents in ANC and PNS need to be further explored and addressed, there is enough evidence that immediate action is needed to address the unique needs of this population. Such changes could include integration of adolescent-friendly services into PMTCT settings and PNS among the HIV*infected adolescents youths who are sexually active with enhanced retention and follow-up activities.

Mullerian adenosarcoma of the endometrium in adolescent girls is extremely rare, with only fifteen cases under 20 years old having been reported to date. We describe here a new case of adolescent Mullerian adenosarcoma and provide an updated review of the previous literature on such rare tumors. Our 19-year-old case presented with a six-month history of prolonged menstruation. She had not yet had any sexual relationship. On gross examination, a fragile mass was seen in her vagina that bled easily. A 4.0×2.0 cm mass was visualized with Magnetic Resonance Imaging (MRI). The tumor seemed to slightly invade the myometrium of the uterine corpus. Transvaginal ultrasound sonography confirmed the presence of a 4.0 cm mass located in the cervix and vagina. The tumor biopsy was diagnosed as a Mullerian adenosarcoma of the endometrium. We performed a Total Abdominal Hysterectomy (TAH) and Bilateral Salpingectomy (BS). The post-surgical specimen was diagnosed as a pT1aNXM0 Mullerian adenosarcoma of the endometrium. The patient did not require adjuvant chemotherapy. She has been monitored every 3 months and has been without recurrence now for 28 months.

We present a case of patient with spontaneous cardiac tamponade related to a very high 2-plasma concentration of dabigatran, an oral direct-acting thrombin inhibitor. By selectively inhibiting thrombin alone, dabigatran may have antithrombotic efficacy while preserving some other hemostatic mechanisms in the coagulation system and thus potentially mitigating the risk of bleeding. Nonetheless, serious bleeding can occur with dabigatran. We illustrate the management of this life threatening hemorrhagic complication by the combination of cardiac surgery, antagonization of the anticoagulant effect (using Idarucizumab, an humanized monoclonal antibody fragment and continuous renal replacement therapy), and monitoring of the effects on coagulation by thromboelastogram.

Marginal Zone Lymphomas (MZL) and Peripheral T Cell Lymphomas (PTCL) are uncommon neoplasms and patients affected by both lymphomas in a lifetime have been rarely reported. Here we present two patients with an initial diagnosis of a MZL who further developed a PTCL. We also present the review of the literature of six other cases of MZL. Half of the cases reported are synchronous and the other half metachronous. Most MZLs reported are MALT subtype. There is no predominant subtype amongst PTCLs. Chronic exposure to proinflammatory cytokines, genetic predisposition or exposure to carcinogenic agents could be possible causes underlying this rare phenomenon.

Whole blood donated for transfusion is processed into four blood products, namely Red Cell Concentrates (RCCs), Fresh Frozen Plasma, Buffy Coats (BCs), and Platelet Concentrates which are obtained by further processing of BCs. These blood products are then given to vulnerable patient cohorts such as anaemic, cancer or post-operative patients requiring RCCs. However, these blood products may contain biomolecules such as inflammatory mediators that may cause adverse yet often overlooked effects in the recipient. Chronic inflammation is characteristic of numerous diseases such as cardiovascular diseases, cancer, type 2 diabetes, rheumatoid arthritis, inflammatory bowel disease, asthma and psoriasis. Such diseases elevate pro-inflammatory cytokines including Interleukin (IL)-1, IL-6 and Tumour Necrosis Factor (TNF)- alpha in the blood. Moreover, pro-inflammatory cytokines also accumulate in blood products during storage, mainly as a result of damaged leucocytes, and may cause Transfusion-Associated Adverse Reactions (TAARs) and transfusion-induced systemic inflammation. Although this is well-known, very little scientific research has investigated the clinical implications and actual adverse effects these abnormal cytokine levels in blood products from donors with underlying chronic inflammatory diseases have on vulnerable recipients, particularly critically-ill patients who are already prone to inflammation.

Major developments have been made in the past two decades to ensure that products are free from viral pathogens. Such improvements were achieved, mainly by the introduction of advanced screening methodologies such as Nucleic Acid Testing. Even though this has vastly improved transfusion safety, bacterial contamination remains a persistent threat. To mitigate this, improved donor arm disinfection, blood diversion pouches and proactive screening of blood components have been implemented by transfusion services all over the globe with great success. This review will focus on how current bacterial screening methodologies have improved over the years and how newer developments within this sector may further reduce the undesired possibility of transfusing contaminated blood products.
Evaluating the Health Care the Level of Electronic Health (e-Health) among Healthcare in Developing Countries and It Application in the Management of COVID-19 Pandemic Outbreak
Authors:   Department of Tele Health Nelson Mandela School of Medicine, University of Kwazulu Natal, South Africa, O Stephen
Published: April 2021

Context: Healthcare institution in developing countries is in a state of great despair, with the lack of basic health infrastructure and support services, compounded with the ever increasing number of old people , chronic diseases and the manifestation of new communicable disease such as the ongoing Severe Acute Respiratory Syndrome- Coronavirus Disease 2019 (SARS-CoV-2, 2019 or COVID-19) pandemic. The massive healthcare disruption cause by the pandemic with respect to the management modality such as social distance and contact tracing re-affirm the importance of adopting the electronic health system in developing countries. This evolutionary trend in Information and Communication Technology (ICT) with the advancement in eHealth is changing the face of health care system globally by bringing healthcare closer to the people in term of cost, accessibility and planning. Despite the well documented benefits of eHealth, the knowledge and the level of adoption of these technologies in most developing countries such as Lesotho is nothing to ride home about (still remains very low). The management of Covid-19 patients has proven that healthcare is not confined; but a structured global system, with people travelling long distances than ever before. Objective: The objective of this article therefore, is aimed at evaluating the state and the level of Electronic Health (e-Health) and its adoption in the management of Covid-19 pandemic outbreak, and to also provide the authorities with information on the importance e-Health technology in this 21 century. The paper therefore reveal that, the level of e-Health in developing country like Lesotho, is still very low, due to lack of political commitment in the provision of needed infrastructure support structures.

The objective of this study was the development, optimization, and validation of a RP-HPLC method for the quantification of reduced glutathione (GSH) and oxidized glutathione (GSSG) in pharmaceutical formulations The separation utilized a C18 column at room temperature with absorption wavelength 210nm. The mobile phase was an isocratic flow of a 95:5 (v/v) mixture of 25mM phosphate buffer (pH 2.7) and methanol with flow rate at 1.0 mL/min. Validation of the method assessed with the methods ability in seven categories: linearity, range, limit of detection, limit of quantification, accuracy, precision, and selectivity. The method show an acceptable degree of linearity with r²=0.9994 and 0.999 over a concentration range of 10-200 μg/mL for GSH and GSSG respectively. The detection limit and quantification limit for GSH 20.7μg/mL and 69.24μg/mL and for GSSG 17.22μg/mL and 57.42μg/mL respectively. The percent recovery of the method was 99.98-100.93 %. Following validation, the method was employed in the determination of glutathione in pharmaceutical formulations in the form of a liposome. The proposed method offers a simple, accurate, and inexpensive way to quantify reduced glutathione.
The Etiology and Secondary Prevention of a Stroke Patient after Successful Catheter Ablation
Authors:   Department of Neurology, China, J Zhao
Published: April 2021

Ischemic Stroke (IS) is one of the leading diseases of mortality and disability worldwide. The rational administration of anticoagulant or antiplatelet drugs is of great importance to prevent stroke recurrence. Here we report an IS patient with a medical history of Catheter Ablation (CA) of Atrial Fibrillation (AF), who had a single vessel scattered lesions in the head Magnetic Resonance Imaging (MRI) scan, which indicated a remarkable correlation with morphology of atherosclerotic artery and artery embolism, while no AF recurrence was detected. At last, we focused on the possible criminal artery and found vulnerable plaques from apparent positive remodeling demonstrated by High-Resolution Vessel Wall MRI (HRVW-MRI). We provided a secondary prevention with the statin and antiplatelet therapy to reduce the risk of bleeding caused by anticoagulation and asked him to follow up Holter every three months. Along with this case report, we describe the imageology, review of literature and treatment outcomes in regard to CA of AF and discuss the prevention of IS.
A new type of quantum walks based on decomposing quantum states
Authors: Kiumi Chusei
Published: April 2021

In this paper, the 2-state decomposed-type quantum walk (DQW) on a line is introduced as an extension of the 2-state quantum walk (QW). The time evolution of the DQW is defined with two different matrices, one is assigned to a real component, and the other is assigned to an imaginary component of the quantum state. Unlike the ordinary 2-state QWs, localization and the spreading phenomenon can coincide in DQWs. Additionally, a DQW can always be converted to the corresponding 4-state QW with identical probability measures. In other words, a class of 4-state QWs can be realized by DQWs with 2 states. In this work, we reveal that there is a 2-state DQW corresponding to the 4-state Grover walk. Then, we derive the weak limit theorem of the class of DQWs corresponding to 4-state QWs which can be regarded as the generalized Grover walks.
Multilevel polarization for quantum Channels
Authors: Goswami Ashutosh , Mhalla Mehdi , Savin Valentin
Published: April 2021

Recently, a purely quantum version of polar codes has been proposed in~\cite{DGMS19} based on a quantum channel combining and splitting procedure, where a randomly chosen two-qubit Clifford unitary acts as a channel combining operation. Here, we consider the quantum polar code construction using the same channel combining and splitting procedure as in~\cite{DGMS19}, but with a fixed two-qubit Clifford unitary. For the family of Pauli channels, we show that polarization happens in multi-levels, where synthesized quantum virtual channels tend to become completely noisy, half-noisy, or noiseless. Further, we present a quantum polar code exploiting the multilevel nature of polarization, and provide an efficient decoding for this code. We show that half-noisy channels can be frozen by fixing their inputs in either the amplitude or the phase basis, which allows reducing the number of preshared EPR pairs compared to the construction in~\cite{DGMS19}. We provide an upper bound on the number of preshared EPR pairs, which is an equality in the case of the quantum erasure channel. To improve the speed of polarization, we propose an alternative construction, which again polarizes in multi-levels, and the previous upper bound on the number of preshared EPR pairs also holds. For a quantum erasure channel, we confirm by numerical analysis that the multilevel polarization happens relatively faster for the alternative construction.
ОСОБЛИВОСТІ РОЗВИТКУ ПРОФЕСІЙНОЇ РЕФЛЕКСІЇ У СТУДЕНТІВ
Authors: Воронова О. Ю.
Published: April 2021

Статтю присвячено висвітленню особливостей побудови тренінгової програми, спрямованої на розвиток професійної рефлексії в майбутніх фахівців закладів дошкільної освіти. Встановлено, що існуюча система професійної підготовки майбутніх вихователів закладів дошкільної освіти не сприяє процесу розвитку професійної рефлексії і підтверджує необхідність створення умов для розвитку професійної рефлексії в процесі навчання у вищій школі. Виявлено, що великій кількості студентів притаманні такі індивідуально-особистісні властивості (наприклад, агресивність, підозрілість, невпевненість у собі, безвідповідальність), які протипоказані педагогічним працівникам і свідчать про професійну нездатність і певні внутрішньоособистісні проблеми (наприклад, психологічні комплекси). Розглянуто особливості формування професійної рефлексії, які зустрічаються в психолого- педагогічній літературі. Висвітлено власний підхід до формування професійної рефлексії в майбутніх фахівців закладів дошкільної освіти в процесі професійної підготовки. На основі узагальнення теоретичних і експериментальних досліджень визначено психологічні умови розвитку професійної рефлексії в майбутніх вихователів закладів дошкільної освіти. Запропоновано змістовно-динамічну модель процесу формування професійної рефлексії в майбутніх вихователів. Зазначено, що вплив на розвиток професійної рефлексії майбутніх фахівців закладів дошкільної освіти опосередковується через низку психологічних властивостей особистості (самоповагу, самоінтерес, самовідношення, впевненість у собі, саморозуміння, емпатію, агресивність, підозрілість, авторитаризм, прагнення до влади й лідерства, відповідальність тощо). Підкреслено, що в запропонованому інтегративному тренінгу формування професійної рефлексії здійснюється не тільки завдяки акцентуванню уваги на свідомій, цілеспрямованій роботі над своїми психологічними особливостями, а й через використання процедури актуалізації рефлексії (яка, зокрема, сприяє набуттю нових умінь, навичок, нових способів професійної діяльності). Передбачається, що робота над цими психологічними властивостями буде позитивно впливати на рівень професійної рефлексії.
ОСОБЛИВОСТІ ІДЕНТИЧНОСТІ В ЮНАЦЬКОМУ ВІЦІ: СУЧАСНИЙ ТЕОРЕТИЧНИЙ І ПРАКТИЧНИЙ РАКУРС

Published: April 2021

Юнацький вік є сенситивним для розвитку ідентичності, що зумовлено потребами його представників в особистісному, професійному і суспільному самовизначенні. Ідентичність визначає цілісність та усвідомлення людиною особистісного і групового аспектів цього утворення. Мета статті – розкрити сучасний ракурс теоретичного та емпіричного вивчення особливостей ідентичності в юнацькому віці. Теоретично встановлено, що в юнацькому віці ідентичність набуває більшої цілісності та усвідомленості. У цьому віці інтенсивно розвиваються особистісна, професійна і соціальна ідентичності. Учні старших класів закладів загальної середньої освіти і студенти закладів фахової передвищої й вищої освіти усвідомленіше визначають власні фізичні, моральні й розумові якості, що засвідчує розвиток їх особистісної ідентичності. Старшокласники здатні усвідомлено обирати майбутню професію, студенти набувають професійних компетентностей, що свідчить про розвиток їх професійної ідентичності. Старшокласники і студенти здатні усвідомлено визначати себе як представника певної соціальної групи, що засвідчує їх соціальну ідентичність. Емпірично вивчалися особливості професійної ідентичності студентів закладів вищої та фахової передвищої освіти, які здобувають спеціальність, пов’язану зі здоров’ям людини, зокрема й майбутніх учителів біології та здоров’я людини, майбутніх медичних сестер. В емпіричному дослідженні, яке проводилося в 2019–2020 рр., взяли участь студенти закладів вищої та фахової передвищої освіти міста Києва. Встановлено статистично значущі відмінності кількісних даних досліджуваних одного вікового діапазону – студентів першого і другого курсів педагогічних університетів і студентів другого і третього курсів медичних коледжів. Виявлено, що кількісні дані актуальності й значущості професійної ідентичності є суттєво вищими для студентів коледжів порівняно зі студентами університетів. Виявлені відмінності пояснюються неоднаковою тривалістю їх фахового навчання, зокрема й практичного, і, відповідно, різною інтенсивністю професійної ідентифікації.

Все це вказує на необхідність розвитку емоційного інтелекту фахівців служби зайнятості насамперед завдяки тренінговому впливу. Метою статті є аналіз результатів упровадження тренінгової програми з розвитку емоційного інтелекту фахівців державної служби зайнятості України. Для реалізації поставленої мети використано методику визначення рівня емоційного інтелекту Н. Холла, а також математично-статистичні методи обробки та аналізу результатів експериментального дослідження: непараметричний U-критерій Манна-Уітні для порівняння двох незалежних вибірок, непараметричний критерій Т-Вілкоксона для порівняння залежних вибірок та непараметричний критерій х² для порівняння результатів формувального експерименту в експериментальній та контрольній групах. Впровадження тренінгової програми з розвитку емоційного інтелекту, що спрямована на забезпечення узгодженого та комплексного характеру формувального впливу на підвищення рівня емоційного інтелекту фахівців ДСЗУ, було реалізовано у формі групового експерименту методом паралельних груп – експериментальної та контрольної. В експериментальній групі після проведення тренінгу спостерігається підвищення високого рівня та зниження низького рівня загального та всіх показників емоційного інтелекту, тоді як у контрольній групі спостерігається тенденція до зниження високого рівня за всіма показниками емоційного інтелекту. Результати дослідження дали змогу зробити висновки про те, що результати експериментальної групи підтверджують ефективність упровадження тренінгової програми з розвитку емоційного інтелекту фахівців ДСЗУ, який виступає важливим чинником професіоналізму у сфері діяльності «людина-людина».

A dimensão da linguagem na polidimensionalidade do mundo espiritual na filosofia das formas simbólicas
Authors: Santos Sanqueilo De Lima
Published: April 2021

A linguagem, pensada em sua estrutura, em seu processo, em suas funções e nas relações variadas do homem com o seu mundo cultural, seja na vertente ou combinação das vertentes mítica, científica, filosófica ou artística, resulta de várias influências filosóficas e científicas sobre a magnum opus de Ernst Cassirer. Busca-se, neste artigo, especificar o significado da função constitutiva e transcendental da linguagem no que Cassirer designa “pregnância simbólica” e reportar esse conceito a um traço hereditário do Romantismo, procedente, sobretudo, de Humboldt, no tocante à capacidade configuradora da linguagem, o que seria pressuposto, inclusive, para o pensamento não monista de Cassirer, na medida em que, em Humboldt, a categoria cassireana de mediação já operava, ainda que sob outro registro e em outro regime metodológico.

Niilismo e Absurdo: Ecos da morte de Deus
Authors: Oliveira André Henrique Mendes Viana de
Published: April 2021

Este artigo procura apresentar inicialmente o conceito de Absurdo, tal como expresso no pensamento de Albert Camus, para em seguida apontar sua relação com o Niilismo problematizado na filosofia de Nietzsche. Para estabelecer essa relação, a noção da “morte de Deus” é sugerida como ponto de articulação entre os dois conceitos. Procuramos apontar ainda uma outra aproximação entre os pensadores no que concerne ao “niilismo ativo” nietzschiano e o conceito de Revolta formulado por Camus.

A QUESTÃO DO PROGRESSO DA CIÊNCIA EM KARL POPPER
Authors: Ribeiro Raimunda Diva de Vasconcelos
Published: April 2021

Este artigo tem como objetivo ampliar a visão do fazer científico, abordando a análise feita por um dos maiores epistemólogos contemporâneos da natureza do fazer científico e de sua dinâmica, de modo a contribuir para a redução do fosso existente na sociedade cintífico-tecnológica entre a visão dos problemas fundamentais do homem e a compreensão da ciência e de sua tecnologia. Assim sendo, o nosso estudo se restringe ao modo de ver de Karl Popper o lado mais interno da ciência, evidenciando igualmente a sua estrutura na ética que suas conquistas tecnológico-instrumentais. A questão a ser tratada é como o autor enfrenta o progresso na ciência. Mais especificamente, a ciência progride? ABSTRACT: The objective of this paper is to broad the analyses about the nature of scientific work and its dynamics based on Karl Popper perspective, one of the greatest contemporary epistemologists, in order to contribute to reduce the gap in the techno scientific society between the human being fundamental problems and the science and technology understanding. Thus, this study is restricted to the Karl Popper perspective concerned to the internal structure of the science and its techno instrumental advances in addition to its ethical issues. The main question to be dealt in this study is how Popper faces the scientific advances. More specifically, does the Science progress?

INTERFACES DELEUZIANAS ENTRE A MEMÓRIA INVOLUNTÁRIA EM PROUST E A LEMBRANÇA PURA EM BERGSON
Authors: Santos Maria Fernanda Novo dos
Published: April 2021

O presente texto procura apresentar possíveis conexões entre os temas da memória involuntária em Proust tal como apresentada na leitura de Deleuze e o conceito de lembrança pura de Bergson a partir de Matéria e Memória.

TÉCNICA, POLÍTICA E PERCEPÇÃO: UM DIÁLOGO ENTRE B. STIEGLER, G. SIMONDON E J. RANCIÈRE
Authors: Dantas Ricardo Avalone Athanásio
Published: April 2021

Em filosofia é comum o empenho em uma busca normativa, normatividade esta que aparece nos processos perceptivos quando o sujeito entra em relação com realidades de uma ordem de magnitude diferente da sua (seja com aquilo que é menor, e assim, manipulável, seja com aquilo que se apresenta como maior que ele e, desse modo, digno de respeito, de ser contemplado, suscitando a aspiração a uma integração com essa ordem maior em questão, ou o desejo de a ela ajustar-se). Não acontece de outra maneira quando se trata de filosofar sobre a técnica – com efeito, em que ordem ou nível de magnitude em relação a nós ela – a técnica – se situa? Pensamos que a primeira condição para responder a tal pergunta é formulá-la em termos políticos. A tese a ser desenvolvida neste trabalho, portanto, é a de que a percepção filosófica da técnica contemporânea, de um modo geral, está permeada pelo preconceito de que a técnica é algo destrutivo e que se encontra fora de controle, demandando uma filosofia moral-normativa capaz de impor-lhe os devidos limites: no entanto, não é preciso permanecer pensando assim; através da articulação entre o conceito estético-político de partilha do sensível (Rancière), e os conceitos (ontogenéticos e político, respectivamente) de individuação psíquica e individuação coletiva (Simondon) e psicopoder (Stiegler), pretende-se demonstrar, não a ineficácia de uma filosofia moral-normativa, mas a necessidade anterior de uma compreensão política da questão da técnica, para que, assim, tal problema possa ser recolocado de forma mais adequada em uma constelação teórica favorável à sua resolução. Tratar-se-á aqui de explicitar a relevância de uma maior sensibilização política dos sujeitos em seu processo de individuação para o caso de haver um real interesse em garantir os meios materiais de manutenção da vida no planeta.
AS CONTRIBUIÇÕES DE LINDA ZAGZEBSKI PARA A EPISTEMOLOGIA DAS VIRTUDES CONTEMPORÂNEA
Authors: Carvalho Sérgio Luís Barroso de
Published: April 2021

Através deste artigo científico pretende-se expor as contribuições de Linda Zagzebski para a teoria da epistemologia das virtudes contemporânea, evidenciando sua inspiração na teoria das virtudes de Aristóteles. A inovação trazida por Zagzebski é a proposta de indistinção entre virtudes morais e virtudes intelectuais. Para a autora, as virtudes intelectuais são um subconjunto das virtudes morais, e assim merecem avaliação conjunta com estas. Por fim, argumenta-se que essa interpretação não implica em um reducionismo das virtudes intelectuais e que pode servir para inspirar uma renovação nas discussões filosóficas contemporâneas.
SUBJETIVIDADE E POÉTICA NO PENSAMENTO DE KIERKEGAARD
Authors: Rocha Gabriel Kafure da
Published: April 2021

A maneira como o movimento kierkegaardiano coloca a subjetividade como verdade se opõe à sistematização da massa e traz a questão de uma visão valorativa da poética como possibilidade de uma ética. A questão que permeia essa ética é o que é o real, este  não pode ser mais simplesmente o idealismo racional, mas uma realidade poética  histórica da subjetividade que faz possível ver que o homem exercer a liberdade da escolha como auto-construção de si. O homem encontra uma incapacidade perante as exigências absolutas e ao se assumir sua subjetividade como verdade acaba precisando passar por um processo de dessubjetivação, de trazer a tona o que está escondido e não-dito por meio da poética. Kierkegaard é um poeta da religião e por sua vez tentará mostrar como a superar a estética através da ética da subjetividade
