Authors: Pal Anjali , Biswas Subhadeep , Danish Mohammad
Published: March 2022

Hexavalent chromium (Cr(VI)) is a well-known carcinogen, and hence its removal from
aqueous media is an important area of research in the field of environmental engineering. Adsorptive
removal and catalytic reduction are the two most common techniques applied for this purpose. In this
regard, nanoparticle-mediated technology has contributed significantly. In the current review article, a
systematic investigation has been carried out to find the latest developments that took place in the domain
of Cr(VI) removal by nanotechnology. The major portion deals with the advancement and application
of the new-age materials, such as carbon nanotubes (CNTs), g-C3N4, MXenes, zero-valent iron
(ZVI), and their composites, for the Cr(VI) remediation purpose. Various interesting mechanisms, as
proposed by different research groups, have been covered. Applications of the nanocomposites in the
real wastewater scenario have also been highlighted. Different characterization techniques often conducted
in order to get insight into Cr(VI) removal process have been mentioned. Some patents related
to this field have been discussed. Lastly, the future scope of the nanomaterials, current challenges, feasibility
of using these nanomaterials in large-scale treatment plants, etc., have been addressed before
concluding the article.

Authors: Georgopoulou Athina , Fotiadou Laskarina , Tryfon Stavros , Daniil Zoi , Boutou Afroditi K.
Published: March 2022

Background:

Although asthmatics may present reduced exercise capacity, data on their cardiovascular responses during exercise testing have been scarcely investigated. The aim of this pilot case-control study is to test: a) whether double product (DP), an index of cardiovascular reserve, differs among patients with severe and mild-moderate asthma, and b) whether DP is associated with asthma control level, physical activity (PA) and exercise capacity, in asthmatics population.

Materials and Methods:

A group of patients with severe asthma (group S) and a matched group of patients with mild-moderate asthma (group M) was studied. All participants completed asthma control and physical activity (IPAC) questionnaires, lung function measurements and six-minute walk test. The exercise capacity (as 6-minute walk distance (6MWD) and corresponding work), the Borg Dyspnea, the rating of perceived excursion and the average PA METS were recorded.

Results:

A total of 18 patients were studied. DP at exercise end was significantly lower in group S, compared to group M (16412.2±4732.1 vs. 18594.8±3984.4 mmHgXbpm; p=0.041) and was moderately associated with % predicted 6MWD (r=0.592; p=0.001). Group S patients were also presented with lower moderate intensity PA, compared to group M, while exercise capacity was similar between the groups. Asthma control level had no impact on exercise capacity nor PA parameters.

Conclusion:

Patients with severe asthma may have impaired cardiovascular reserve as established by DP, even when exercise capacity is indifferent from patients with milder disease. As an easy-to-assess parameter, DP may offer further information in the functional evaluation of these patients.
Prevalence of and Factors Associated With Transfusion-Transmitted Infections Among Multi-transfused Patients, Sana'a City, Yemen, 2019
Authors: Moghalles Suaad , Al Serori Abdulwahed , Alhadi Abd Alrahman , Shamsan Ahmed
Published: March 2022

Background

Multi-transfused patients (MTPs) are at higher risk of transfusion-transmitted infections (TTIs) due to their frequent need for blood transfusion. Nevertheless, little is known about the prevalence of TTIs among MTPs and its associated factors in Yemen.

Objective

We aimed to determine the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV and its associated factors among MTPs.

Methods

A cross-sectional study was conducted at the Yemeni Society for Thalassemia and at Pediatric Leukemia Unit in Sana’a City. The calculated sample size of 357 was increased to 405 to overcome any nonresponses. By using probability proportional to size sampling, 80 patients with thalassemia, 240 patients with sickle cell anemia, and 85 patients with leukemia were randomly selected. Data were collected through face-to-face interviews with patients or their caretakers by using a predesigned questionnaire covering demographic, socioeconomic characteristics and TTI-associated factors. Blood samples were drawn and were tested for HBsAg, anti-HCV, and HIV I and II by using an electrochemiluminescence immunoassay.

Results

The overall prevalence of TTIs among MTPs was 13.1% and was significantly highest (37.3%) among patients with leukemia. HBV (16.2%) and HCV (27.5%) prevalence were also highest among patients with leukemia. Only 2 (0.04%) patients were found to be HIV positive among patients with sickle cell anemia. Coinfection with HBV and HCV was only found in 5 patients with leukemia. There was a significant association between TTIs and the receipt of >30 blood units. Only 35% of MTPs were found to be vaccinated against HBV.

Conclusions

Our findings raise an alarm for the existence of a high risk of TTIs among MTPs, especially among patients with leukemia and those who undergo an increasing number of transfusions. Using advanced technology in blood screening and strict infection prevention during transfusion should be adopted. The rational use of blood/blood substitutes and ensuring that MTPs are vaccinated against HBV are recommended.
Influence of Forced Online Distance Education During the COVID-19 Pandemic on the Perceived Stress of Postsecondary Students: Cross-sectional Study (Preprint)
Authors: Šorgo Andrej , Crnkovič Nuša , Gabrovec Branko , Cesar Katarina , Selak Špela
Published: March 2022

BACKGROUND

One of the most significant changes in the majority of postsecondary educational institutions was the closure of those institutions and the shift of educational activities to online distance learning formats as a result of the COVID-19 pandemic. Closure combined with forced online distance education (FODE) was a cure with many side effects, 1 of them being the effect on students’ mental health and, more specifically, levels of stress. Due to the novelty of the situation, there have been no studies so far designed to link satisfaction with online study, feelings toward the study obligations, and stress among students.

OBJECTIVE

The aim of the study is to assess the perceived stress of Slovenian postsecondary students in order to identify the online study–related factors affecting or acting as a covariate during the COVID-19 lockdown.

METHODS

Data collection was conducted through a self-reported survey as part of a large cross-sectional study based on data collected from postsecondary students from a number of higher educational institutions. The random sample consisted of 4455 individuals. The Perceived Stress Scale (PSS-4), Satisfaction with Online Study Scale (SAT-5), and Feelings Towards Study Obligations Scale (FETSOS) were used to assess the constructs and the relations observed within the study.

RESULTS

The results indicate that more than half of all respondents reported high levels of stress. The difference in the reported levels of perceived stress between genders were statistically significant (N=4454, F2=56.719, P<.001, Cohen d=0.35). Overall, the results suggest that a decline in the motivation to study, the quality of internet and mobile connections, and the presence of distracting factors in the study space were the 3 main factors related to the students’ negative emotions as associated with the timeliness, performance, and quality of the study obligations. Furthermore, the results show that the level of satisfaction with online study affected stress such that the higher the satisfaction, the lower the stress. Moreover, the more positive feelings connected with the timeliness, performance, and quality of the study obligations that the students felt, the more satisfaction they reported with online study and, thus indirectly, lower stress and less negative feelings.

CONCLUSIONS

The findings of this study call for implementing structures and measures targeted at stress reduction, working conditions, and pedagogy with regard to FODE.

Published: March 2022

BACKGROUND

Online information on COVID-19 vaccination may influence people’s perception and willingness to be vaccinated. Official websites of vaccination programs have not been systematically assessed before.

OBJECTIVE

This study aims to assess and compare the readability and content quality of web-based information on COVID-19 vaccination posted on official/governmental websites. Furthermore, the relationship between evaluated website parameters and country vaccination rates were calculated.

METHODS

By referring to an open data set hosted at Our World in Data, the 58 countries/regions with the highest total vaccination count as of July 8, 2021, were identified. Together with the websites from the World Health Organization and European Union, a total of 60 vaccination campaign websites were targeted. The “frequently asked questions” or “questions and answers” section of the websites were evaluated in terms of readability (Flesch Reading Ease score and Flesch-Kincaid Grade Level), quality (Health On the Net Foundation code [HONcode] certification and Quality Evaluation Scoring Tool), and content stating vaccination duration of protection and potential side effects.

RESULTS

In terms of readability, the Flesch Reading Ease score of the vaccination frequently asked questions websites ranged between 11.2 and 69.5, with a mean of 40.9 (SD 13.2). Meanwhile, the Flesch-Kincaid Grade Level ranged between 6.5 and 17.6, with a mean of 12.1 (SD 2.8). In terms of quality, only 2 websites were HONcode certified, and the Quality Evaluation Scoring Tool score of the websites ranged between 7 and 20, with a mean of 15.3 (SD 3.1). Half of the websites (25/50) did not present a publication date or date of the last update. Regarding the duration of protection offered by the vaccines, 46% (23/50) of the websites stated that they do not know, and another 40% (20/50) did not address it. Five side effects of the vaccinations were most frequently mentioned, namely, fever/chill (41/50, 82%), various injection site discomfort events (eg, swelling, redness, or pain; 39/50, 78%), headache (36/50, 72%), fatigue (33/50, 66%), and muscle/joint pain (31/50, 62%).

CONCLUSIONS

In general, the content quality of most of the evaluated websites was good, but HONcode certification should be considered, content should be written in a more readable manner, and a publication date or date of the last update should be presented.

Published: March 2022

BACKGROUND

The recent COVID-19 pandemic has highlighted the weaknesses of healthcare systems around the world. In the effort to improve the monitoring of cases admitted to Emergency Departments (ED), it has become increasingly necessary to adopt new innovative technological solutions in clinical practice. Currently, continuous monitoring of vital signs is only performed in patients admitted to the Intensive Care Unit (ICU).

OBJECTIVE

The study aims to develop a smart system that will dynamically prioritize patients through continuous monitoring of vital signs using a wearable biosensor device and recording of meaningful clinical records, and estimate the likelihood of deterioration of each case using Artificial Intelligence (AI) models.

METHODS

The data for the study will be collected from the ED and COVID-19 inpatient unit of the Hippocration General Hospital of Thessaloniki. The study is carried out in the framework of the COVID-X H2020 project, funded by the European Union. For the training of the neural network, data collection will be performed from COVID-19 cases hospitalized in the respective unit. A wearable biosensor device will be placed on the wrist of each patient, which will record the primary characteristics of the visual signal related to breathing assessment.

RESULTS

The study will take place over a period of six (6) to eight (8) months.

CONCLUSIONS

The proposed study represents a novel approach of Edge AI method.
Evolution of an online support group: public forum to private Facebook mother’s group (Preprint)
Authors: Gleeson Danielle , Jones Christian , Craswell Alison
Published: March 2022

BACKGROUND

Women in pregnancy and motherhood are increasingly accessing online mothers’ groups as a source of information and support.

OBJECTIVE

To understand the evolution of, and interactions within, an online mothers’ group over ten years, commencing in a large public forum and breaking away to form a small, private Facebook group

METHODS

A qualitative interpretive study, using online textual postings

RESULTS

The findings demonstrated an evolution of childbearing women’s information and support needs, interaction types, individual and community focus, and trust and relationship building within a group of women participating in online mothers’ groups. Large public forums are mostly a space for self-motivated information and advice seeking with only a small number of women engaging in reciprocal support activities. For those able to build relationships, a small, private online group can foster a sense of belongingness and community, through active participation and mutual support, which can evolve with women’s needs over many years.

CONCLUSIONS

Large online public forums can inhibit relationship building through the diffusion of social responsibility and the burden of reciprocity. However, small private online groups can foster participation and reciprocity, leading to access sustained and appropriate support that evolves with their needs throughout the phases of childbearing and beyond.

Published: March 2022

Abstract: A Smart scarecrow is used to scare the birds and to the animals to save the crop in the fields. A farmer put the smart scarecrow within the middle of the sector to save lots of his crop from the birds and animals. We have seen that smart scarecrow has no movement when the birds are available field. A smart scarecrow is a decoy or mannequin, often in the shape of a human. Humanoid scarecrows are usually wearing old clothes and placed in open fields to discourage birds from disturbing and feeding on recently cast seed and growing crops. Scarecrows are used across the planet by farmers, and are a notable symbol of farms and therefore the countryside in popular culture. The common form of a smart scarecrow is a humanoid figure dressed in old clothes and placed in open fields to discourage birds such as crows or sparrows from disturbing and feeding on recently cast seed and growing crops. Machinery like windmills are employed as scarecrows, but the effectiveness lessens as animals become conversant in the structures. Farming contributes a major income to the Malaysian economy. It is an enormous concern to farmers once they are far away from their crops and exposing it to crops’ threat like crow damaging the crops and theft. Farming has contributed to nearly up to 22% of a country’s. Keywords: Sensor, Flapping mechanism, Linear Motion, Buzzer, 360º Wi-Fi Camera
Real Time Object Detection using SSD and MobileNet
Authors: Palwankar Tejal , Kothari Kushal
Published: March 2022

Abstract: This Accurate Real-time object detection needs faster computation power to identify the object at that specific time. The accuracy of object detection has increased drastically with the advancement of deep learning techniques. We incorporate a stateof-the-art method for object detection to achieve high accuracy with real-time performance. The state-of-the-art methods are subdivided into two types. The first is one-stage methods that prioritize inference speed, and example models include YOLO, SSD, and RetinaNet. The second is two-stage methods that prioritize detection accuracy, and its example models include Faster R-CNN, Mask R-CNN, and Cascade R-CNN. Among all these, Faster-RCNN and SSD have better accuracy, while YOLO performs better when speed is given preference over accuracy. A major challenge in many of the object detection systems is that it is dependent on the other computer vision techniques for helping the deep learning-based approach, which results in slow and non-optimal performance. In this paper, we have used a deep learning-based approach to solve the matter of object detection in an end-to-end fashion. Deep learning combines SSD and Mobile Nets to perform the efficient implementation of detection and tracking.SSD eliminates the feature resampling stage and combined all calculated results as a single component. MobileNet is a lightweight network model that uses depth-wise separable convolution for the places which lacks computational power like mobile devices (eg: laptop, mobile phones, etc). This algorithm performs efficient object detection while not compromising on the performance The main purpose of our research is to elaborate the accuracy of an object detection method SSD and the importance of the pre-trained deep learning model MobileNet. The resultant system is fast and accurate, thus aiding those applications which require object detection Keywords: Object Detection, CNN, TensorFlow object detection API, SSD with MobileNet

Aim: A field investigation was conducted during 2016-17 and 2017-18 to assess the relative performance of micro irrigation methods with regard to yield, water use, economics, nitrogen indices and energy use pattern in rabi groundnut on irrigated Alfisols. Methodology: One conventional and three micro-irrigation methods viz., drip, sprinkler and rain gun were evaluated in rabi groundnut. Besides growth, reproductive traits and pod yield, the information on nodule count, water use efficiency, economic benefits, nitrogen and energy indices was generated. High yielding, high water, power and energy use efficient irrigation scheduling method for rabi groundnut cultivation was identified. Results: Drip irrigation @ 0.8 Epan + fertigation at recommended dose of fertilizers not only recorded better growth and reproductive attributes but also resulted in 8-10% higher dry pod yield over sprinkler irrigation, raingun irrigation and conventional method. Besides, drip method also recorded higher water use efficiency (6.31 kg ha-1 mm-1) and higher economic yield per kg N applied (95.9 kg). This method also proved to be energy efficient and remunerative with higher net income (` 70,280 ha-1). Interpretation: Scheduling of irrigation and fertigation through drip method helped in achieving higher pod yield, water and nitrogen use efficiency utilizing less power and energy in groundnut cultivation.
Predation and prey preference of the exotic snail Anentome helena on two freshwater snails: implications for species invasion
Authors:   Department of Zoology, University of Calcutta, Kolkata-700 019, India, Karmakar R. , Paul P. ,   Department of Zoology, University of Calcutta, Kolkata-700 019, India, Aditya G. ,   Department of Zoology, University of Calcutta, Kolkata-700 019, India
Published: March 2022

Aim: The aim of the present study was to estimate the probable impact of predation of the exotic snail Anentome helena on two co-occurring freshwater snails, Racesina luteola and Physella acuta, in the laboratory set-up. Methodology: In the initial experiment, the predatory efficiency of A. helena was observed using R. luteola and P. acuta as prey, separately, under varying prey and predator densities. In the following experiment, the prey snails were provided in both conspecific and heterospecific conditions with different predator densities to deduce the prey preference of A. helena, if any. Results: The experiments show that A. helena can consume a considerable number of R. luteola and P. acuta. The predation rate of A. helena varied significantly (p< 0.0001) with different sizes of prey, prey and predator densities. Although the predation rate differed among conspecific and heterospecific prey conditions, A. helena did not demonstrate any significant prey preference towards any of the prey. Interpretation: The study revealed that the chance dispersal of predator A. helena from household aquaria to natural habitats may directly impact the population of the freshwater snail R. luteola and P. acuta.

Authors: Wiem Barbaria , Khamassi Ichrak , Gaaloul Khouloud , Hamouda Samia , Gritli Said
Published: March 2022

Tracheal hemangioma is a rare vascular tumor in adults and children.
Recurrent hemoptysis and chronic cough are main symptoms revealing the
disease. We report here a case of tracheal hemangioma in an
eight-year-old girl. She was admitted to the pediatric department of
Habib Bougatfa Hospital of Bizerta in Tunisia because of recurrent
hemoptysis. Diagnosis was performed using computed tomography and
bronchoscopy. Beta blocker therapy was not efficient. Radical treatment

should be considered as a cause of recurrent hemoptysis when routine
biological and radiological investigations are negative.
Temperature Dependence of Cleavage Fracture Toughness for an Ultra High Strength Martensitic Steel
Authors: Barbosa Vitor S. , Gomes Vinicius M. C. , Ruggieri Claudio
Published: March 2022

This work conducts an exploratory evaluation of the brittle fracture
behavior for a high-strength martensitic steel using conventional
three-point bend SE(B) and pre-cracked Charpy V-notch (PCVN) specimens.
A primary purpose of this study is to verify the effectiveness of the
Master Curve methodology in providing a reliable estimate of the
reference temperature ( T 0 ) derived from fracture toughness data sets
measured in the ductile-to-brittle transition region (DBT) of a ultra
high strength, low alloy martensitic steel. Fracture toughness testing
conducted on three-point bend SE(B) specimens and pre-cracked Charpy
(PCVN) configurations at different test temperatures in the DBT region
provides the cleavage fracture resistance data in terms of the J
-integral at cleavage instability, J c , and its corresponding K J c
-values for the tested material. While this class of ultra high strength
steel having a martensitic microstructure is currently beyond the reach
of ASTM E1921, the analyses described here show that the predicted
normalized curves of median fracture toughness vs. temperature
are in good agreement with the experimental measurements.

Objectives: To determine the relationship between serum levels
of oxidative stress (OS) parameters and regional cerebral oxygen
saturation (rSO2), as well as postoperative clinical outcomes in
patients undergoing coronary artery bypass graft surgery (CABG).
Materials and Methods: This prospective observational study
included 64 adult patients undergoing elective CABG [on-pump-CABG
(n=48) and off-pump CABG (n=16)]. The OS level was determined
according to total oxidant status and malondialdehyde. OS levels and
rSO2 values were measured intraoperatively at three-time points (T1:
after induction, T2: 15min before aortic cross-clamp removal or before
the last distal anastomosis, T3: 15min after aortic cross-clamp removal
or the last distal anastomosis). Results: In the on-pump group,
OS levels at T2-3 and lactate values at T2-3 were found to be higher
(p=<0.001), rSO2 at T2 was lower (p=0.024). There was a
negative correlation between rSO2-T2 values and OS parameters, lactate
levels at T2-3, aortic clamp time, postoperative mechanical ventilation
(MV) time, and length of stay (LOS) in the ICU. In the multivariate
linear regression analysis [F(2.61)=8.26, p=0.001], lactate values
at T2 were found to be the only factor affecting the OSI-T2 index
(Beta=0.388, p=0.006). Conclusıons: In this study, we observed
that OS levels were increased and rSO2 values were relatively low during
on-pump CABG procedures, furthermore, lower rSO2 values were associated
with increased OS levels and poor postoperative clinical outcomes. The
OS response and cerebral oxygenation could be improved in off-pump CABG
by limiting global ischemia, resulting in a favourable postoperative
outcomes such as less MV time and LOS in the ICU.
A New Deacidification Strategy for Crude Vegetable Oil：Removal of Free Fatty Acids via Photobiocatalytic Decarboxylation
Authors: Zhang Xizhen , Ma Yunjian , Qin Xiao-li , Hollmann Frank , Wang Yonghua
Published: March 2022

Crude vegetable oils can contain sometimes high concentrations of free
fatty acids (FFAs) forming during manufacture, processing,
transportation and storage. As FFAs may impair the senoric and olfactory
properties of vegetable oil products, efficient deacidification
strategies for crude vegetable oils are highly desirable. In this work,
crude vegetable oils were deacidified by using a recently discovered
photodecarboxylase from Chlorella variabilis NC64A (CvFAP)
heterologously expressed in Escherichia coli catalyzing selective
decarboxylation of FFAs while leaving esters unmodified. Using this
novel approach, deacidification degree of 8 different crude vegetable
oils with varying initial FFAs content (1.62%–39.68%) reached
83.17%–98.30% after 6 h at 30 ℃. The highest degree of
deacidification (99.33% after 6 h) was achieved for crude rice bran oil
with 13.98% initial FFAs under optimized conditions. The
deacidification reaction was negatively affected by increasing crude
vegetable oil concentration, which was probably due to low value of
solvent accessible surface area when surrounded by high mole of FFAs.
This study developed mild reaction conditions and simple deacidification
making the production process of crude vegetable oils environmentally
friendly.

Hoy la RSE (Responsabilidad Social Empresarial) es una forma de acercar a las organizaciones, empresas e instituciones a una nueva conciencia y respeto por el contexto ambiental. Así, se puede señalar que si bien no existen muchas organizaciones del sector secundario en el departamento de Caquetá, existe una amplia cantidad de veredas y asociaciones de agricultores dedicadas a la extracción de madera, carbón, pesca y ganadería de explotación extensiva y poca productiva; es así como en el presente estudio se muestra la necesidad de establecer metas enfocadas a describir la importancia e impacto de la RSE sobre la biodiversidad en el departamento de Caquetá en la Amazonía, de la misma manera que el presente estudio toma un enfoque cualitativo porque se basa en referencias teóricas y consultas a diversas bases desis datos nacionales e internacionales, en donde el tipo de investigación utilizada es descriptiva. Como resultado, se puede notar que, a nivel internacional, a partir de 2015, la Asamblea General de las Naciones Unidas ha desarrollado un plan con 17 metas, una de las cuales está directamente dirigida a reducir la desertificación, proteger, restaurar y promover la sostenibilidad de los organismos biológicos. En donde Colombia ha desarrollado diversos programas y estrategias de gestión ambiental a nivel nacional, que incluyen pagos por servicios ambientales, incentivos monetarios, entre otros. Finalmente, a nivel local, se concentra el estudio en el departamento del Caquetá en donde en la actualidad existe un alto nivel de deforestación, lo que conduce a la destrucción de ecosistemas biológicos.

Twenty-five rice genotypes with two Egyptian rice varieties: Giza 178 and Sakha 105 were all cultivated in a Randomized Complete Block Design (RCBD) with two replications under saline soil at at El_Sirw Agriculture Research Station northern part of Delta, Egypt during the growing season 2012. This study aimed to evaluate the potential divergence among tested genotypes and to define the role of agronomic traits in the total variation by using principle component analysis. Results showed that high variability was noticed between the testes genotypes, and indicated that only four principle components PC1, PC2, PC3 and PC4 were significant as they had an Eigenvalue greater than 1.0 (2.3967, 2.1444, 1.7225, 1.0618) respectively, explained together 73.3% of existed variation between genotypes. The first principle component PC1 explained the highest variation 24%, followed by other components PC2, PC3 and PC4 which explained (21.4, 17.2, 10.6) % of the total variation. Results also revealed that days to flowering and number of filled grains per panicle were associated with PC1, whereas three traits (tillers per plant, panicles number per plant and thousand grain weight) were gathered in PC2, and the PC3 consisted of (panicle length, panicle fertility and grain yield per plant), while the last component PC4 contained both traits flag leaf area and plant height. It was concluded that the divergence between rice genotypes in our study provide a wide genetic base for breeders to improve rice
The basic mechanism of the intellectual cognition in Thomas Aquinas
Authors: Milidrag Predrag
Published: March 2022

The article analyses and interprets the basic structure of the process of intellectual cognition in Thomas Aquinas. After a short chapter on sense cognition, Aquinas?s understanding of the active intellect is presented, that is the illumination of the phantasms and the abstraction of the intelligible species by the active intellect. Special attention is given to the difference between the phantasm and the intelligible species. Consideration of the possible intellect shows two steps, the reception of the intelligible species and the creation of the concept, inner word or intentio intellecta. After that, two basic operations of the possible intellect are analyzed, simple apprehension and judgment. The article ends with a series of questions, pointing to possible problems in Aquinas?s understanding.
Schapp’s entanglement in stories
Authors: Micic Nemanja
Published: March 2022

This paper demonstrates some of the fundamental positions taken by the so-called ?philosophy of stories?, set forth by Wilhelm Schapp, in the middle of the 20th century. Our research accentuates the first Schapp?s study regarding the philosophy of stories (The Entanglement in Stories), with the aim of showcasing propinquity of such project with other disciplines and authors, as well as to draw attention to the possibility of crystallizing a hopefully potent ?narrative method?. The implementation of the aforementioned method would potentially lead to expounding the idea of the intrinsically narrative dimension of any kind of language event. Thus formulated narrative method also exhibits the fact that language incessantly produces the pure multiplicity of contingent stories. Another potential merit of this approach is the prospect of understanding language in different, more authentic terms: we would insist on putting forward its self-producing and self-effacing character, rather than persisting on the usual analyses which often emphasize the understanding of language as an ?expression of thought?, or as an ?information conveyor?.
