Ciudad poscovid-19 desde antes del covid-19: autoetnografía
Authors: Muñoz-Escalante Mauricio
Published: May 2021

Autoetnografía sobre el llamado a rediseñar las ciudades según las condiciones que impone la pandemia del covid-19 hoy en la tierra. Se plantea que las fronteras entre la civilización humana y el mundo natural se asemejan a las que hemos creado entre ciudades y países, y acordemente se marcan de manera diferente dependiendo del lugar que se ocupa en una geografía de centros y periferias como la actual. Se ilustra cómo el cruce de un borde tiene su origen en la forma de hacerlo, literalmente al llenar un formato, y metafóricamente al desarrollar formas urbanas que lo permitan. Se sugiere que las ciudades informales como las colombianas no tendrían herramientas teóricas para hacer eco al proyecto global de replantear urbes, sin haberlas planeado de antemano. Se concluye que el discurso de descolonización empieza con aprender a oírse, para luego emitir la propia voz, y una opción válida todavía es decir no.

Coronavirus und Medienfreiheit
Authors: Hänni Peter
Published: May 2021

Derzeit beherrscht das Coronavirus die Schlagzeilen. Weniger gefragt ist Kritik. Mit einigem Recht können die Behörden darauf hinweisen, dass jetzt konkretes Tun gefragt ist und nicht kleinliche Mängelbuchhaltung. Die Grenze zur Behinderung der Arbeit von Medienschaffenden ist allerdings nahe und die Versuchung der Instrumentalisierung der Medien nicht zu übersehen. Nachstehend sollen die Befugnisse und die Grenzen der Behörden in Notlagen aus rechtlicher Sicht dargestellt werden, was gleichbedeutend mit der Frage ist, wie weit die verfassungsmässigen Rechte der Medienschaffenden wie z.B. das Recht auf Zutritt zu öffentlichen Verhandlungen in Notlagen eingeschränkt werden dürfen.
Ehrverletzung oder Gesellschaftskritik?
Authors: Denise Buser Nadine Zurkinden und
Published: May 2021

Liegt eine strafrechtliche Ehrverletzung vor, wenn der Papst Abtreibung mit Auftragsmord gleichsetzt? Dieser Frage wird hier nachgegangen. Dabei wird der Sachverhalt mit den deutschen «Soldaten-sind-Mörder»-Urteilen verglichen. Es zeigt sich, dass bei der Aussage des Papstes zumindest eine problematische Nähe zu einer strafrechtlich relevanten Diffamierung vorliegt. Denn während beim Tucholsky-Zitat «Soldaten sind Mörder» die (pazifistische) Kritik an Kriegsführung und dem damit verbundenen obligatorischen Militärdienst im Vordergrund stehen, wird beim Papst-Vergleich gerade auch das angeblich individuelle Fehlverhalten der einzelnen Frau angeprangert.

Ayurveda, The science of life, since its origin is serving the mankind throughout in health & disease state of life. Shalakyatantra, one of its specialized branch deals with the science of Ophthalmology, Otorhinolaryngology, Orodental surgery & Head; was contributed and developed by Rajrishi Nimi, the King of Videha, who was a colleague of Atreya, Punarvasu, Dhanwantri, Bharadwaja, Kashyapa etc. The available literature related to this speciality is reproduced from original text of Nimitantra in Uttartantra of Sushruta samhita.
Correlation of Tritiya Patalagata kach with modern science is varies according to different authors, but according to some it can be correlated with different stages of senile immature cataract after considering the signs and symptoms and histological changes in the lens.One of the oldest concepts is that precipitation, denaturation, coagulation or agglutination of soluble lens protein is responsible for lens opacification. Accordingly after considering signs and  symptoms, here correlating Kaphaja kach with Senile Immature Cataract. Senile immature Cataract is also called as age related Cataract. It is one of the major causes for the age related visual impairment and blindness. It affects 11.5- to 15.5 million persons worldwide. At certain age of life, opacification of lens starts in everyoneâ€™s eye which leads to gradual diminished vision or loss of vision. which means gradual opacification leads to cataract. According to modern science, senile immature cataract can be correlated with kaphaja kach. In modern science surgery is the only treatment available in cataract. In Ayurveda our Acharyas have mentioned various procedures like anjana, aschotana, pariseka, tarpana to delay kach or arrest the procedure of opacification. which can be useful in senile immature cataract.
Doing Things with Words
Authors: Mills Philip
Published: May 2021

Against the apparent casting away of poetry from contemporary philosophy of language and aesthetics which has left poetry forceless, I argue that poetry has a linguistic, philosophical, and even political force. Against the idea that literature (as novel) can teach us facts about the world, I argue that the force of literature (as poetry) resides in its capacity to change our ways of seeing. First, I contest views which consider poetry forceless by discussing Austin’s and Sartre’s views. Second, I explore the concept of force in the realm of art—focusing on Nietzsche’s philosophy and Menke’s Kraft der Kunst—and the relations between linguistic, artistic, and political forces. Third, I consider how the transformative force of poetry can be considered political by turning to Kristeva’s Revolution in Poetic Language and Meschonnic’s conception of poetry according to which the poem does something to language and the subject. To illustrate this transformative force of poetry, I analyse Caroline Zekri’s poem ‘Un pur rapport grammatical’. I therefore think of poetry not only as doing something with language, but also as doing something to language. To rephrase Austin’s famous title, and thus reverse his evaluation of poetry, poetry might reveal to us not only How to Do Things with Words, but how to do things to words and, through this doing, how to transform and affect the world.
Development and In‑Vitro Evaluation of Colon Specific Indomethacin Matrix Tablet for the Treatment of Inflammatory Bowel Disease
Authors: Deshmukh Rohitas
Published: May 2021

IBD is a chronic inflammatory disease of the gastrointestinal tract, particularly small and large intestine consisting of ulcerative colitis (UC) and Crohn’s disease (CD). Oral route of drug delivery is considered as the most appropriate route of drug delivery of drugs. But this route has certain limitations of poor bioavailability due to gastric degradation and increase in dose size and frequency. Therefore, the present aim of the study is to prepare and evaluate Indomethacin loaded matrix tablet using guar gum, HPMC (release controlling polymer) and citric acid to facilitate the drug solubility in the colon. A total 8 different formulations were prepared by wet granulation method and coated with Eudragit S 100 polymer a pH dependent enteric coating polymer which dissolve at colonic pH (7.4) and specifically release the drug in the colon region in sustain release fashion. The granules evaluated for its micrometrics properties and tablets were evaluated for its hardness, thickness, friability, weight variation, drug content, and in‑vitro drug release studies. The % cumulative drug release profile of all tablets was little and insignificant at pH 1.2 and 6.8. In colonic pH the coating dissolves tablets starts to release drugs. Among all the formulation the formulation F3 having guar gum and HPMC ratio 3:1 shows a maximum release of drug of 80.41±6.5%. At 24 h. The study demonstrated that the prepared tablets can release the Indomethacin in sustained release manner and helps in management of IBD with reduced side effect of the therapy. The results of this study show that oral administration of aspartame (250mg/kg body weight) was correlated to a significant increase in the lipid profile, fasting blood glucose and some marker enzymes and this increase is time related.

Authors: Hasan Hiba Ali , Salman Afrah , Emilia Abdulmalek
Published: May 2021

Pursuing our interest in bioactive heterocyclic compound, two benzoimidazoquinazoline derivatives were synthesised using both microwave-assisted and classical heating methods. Structures of the compounds were confirmed by standard spectroscopic methods and elemental analysis. The target scaffolds were incidentally found to emit blue light when exposed to ultraviolet light. Consequently, a photoluminescence characterization was carried out as a part of characterization protocol. The anticancer activities of the benzimidazoquinazoline compounds were investigated using both methylthiazol tetrazolium (MTT) and the high content screen (HCS) assays against liver hepatocellular cells. The results showed a significant reduction in the inhibitory concentration of the cancer cells by 1 and 2.6 fold when exposed to compounds (3a) and (3b), respectively. The high content screen (HCS) was conducted for compound (3b) and the results showed high toxicity towards the cancer cells.

Published: May 2021

Allium cepa (onion; Liliaceae family), herbaceous annual plant and reported Sulphur based amino acids with many minerals including vitamins. Inspite of various medicinal uses of this plant as food and also showed various beneficial effects. The antimicrobial activity of aqueous extract from Allium cepa (onion bulb) was evaluated against bacterial strains using disc diffusion method. In contrast, inflammatory response or inhibition of T cell antigenic response was evaluated using typhoid vaccine and swine flu vaccine in Swiss mice. These studies were conducted according to ethical guidelines and determining T cell proliferation including estimation of cytokines from cell culture supernatant and also measuring its hemolytic activity. The results showed that aqueous extract show the highest inhibition rate against Pseudomonas aeruginosa and Salmonella enteritidis. In mice model studies, aqueous extract at higher doses showed inhibition in antigen specific T cell proliferation and also declining in the level of IFN-gamma production but enhancement in IL-4 production. In addition, aqueous extract at higher concentration does not showed any hemolytic activity. Overall, this study provides evidence for the presence of secondary metabolites in aqueous extract that probably interferes with bacterial growth (antimicrobial) and also declining in antigenic specific proliferation (i.e. anti-inflammatory) which would prevent and inhibit initiation and progression of many diseases.

Published: May 2021

Chlorpheniramine Maleate (CPM) and Glyceryl Guaiacolate (GUA) are the β‐lactum antibiotic drug. Sensitive, precise, accurate and simple, UV spectrophotometric methods have been developed for the simultaneous estimation of Chlorpheniramine Maleate (CPM) and Glyceryl Guaiacolate (GUA) in dosage form. Two spectrophotometric methods (simultaneoue equations and Q‐Absorbance ratio) were applied for the determination of the drugs as mixture. The maximum absorbance of drug in solvent mixture composed of water – acetontrile – methanol in a ratio of (80% H2O – 10% ACN – 10% MOH) was found to be at (261.4 nm and 273 nm) for CPM, GUA respectively, and the Q – isosbestic point was found at 270.4 nm. These wavelengths were selected for the analysis of drugs as mixtures standard and in the manufactured samples using the two developed methods. The methods were linear in the range of (1- 100) μg/mL for (CPM, GUA), with an R2 of (0.9996) for CPM and GUA respectively in the mixture. Recovery means were found to be (99.79 % - 100.30 %) for the standard drugs CPM and GUA respectively and in formulating drugs was found to be (99.71 – 100.41 %). LOD and LOQ were established and found to be (0.1 and 0.33) for CPM and GUA respectively. The method was applied for the estimation of the active gradient of the drugs in different samples of manufactured dosage. The accuracy of method was validated by mean percentage recovery, which was found to be in the acceptable range.

A field study was conducted to investigate the effect of botanical extracts i.e. neem oil emulsified with NIFA adjuvant, turmeric and hinge crude extracts and neem oil in combination with white oil emulsified with NIFA adjuvants and the synthetic insecticides i.e. emamectin and bifenthrin on the control of Helicoverpa armigera on tomato crop. It was found that the highest control of H. armigera was observed for emamactin and the lowest was recoded for control. Similarly, the highest yield of tomato was recoded for neem-white oil treatment and lowest infestation was recorded for emamactin benzoate. The neem oil and neem oil in combination with white oil emulsified with NIFA adjuvant also showedbetter results than bifenthrin and hinge and turmeric crude extracts in controlling the larvae population of H. armigera. On the basis of these findings, neem oil and neem oil combined with white oil is the best management technique for controlling the H. armigera, as these agents pose least environmental hazards and are relatively nontoxic to beneficial insects and humans and readily photodegrade.

The present study investigates the phyto-accumulation capacity of two cultivars of sunflower (Helianthus annuus L.) for heavy metals. Analysis of the data recorded ten weeks after sowing indicated that heavy metal application had significantly (p<0.05) affected all the parameters under study. Interaction of EDTA x cultivar and EDTA x cultivar x heavy metal had significantly (p<0.05) affected root fresh weight, root dry weight and heavy metal accumulation. EDTA application had significant (p<0.05) effect on heavy metal accumulation when data was noted ten weeks after sowing. The data also revealed that maximum plant height, number of leaves/plant, shoot fresh weight and dry weight, root fresh and dry weight was noted in control pots (0 mg/kg heavy metal). The suggested that maximum shoot fresh weight shoot dry weight, root fresh weight and root dry weight was noted in pots kept at control with San Sun-33 when applied with 5 mM EDTA. Similarly, maximum heavy metal accumulation was recorded in treatment sown of HiSun-33 applied with 5 mM EDTA and 50 mM chromium. Maximum root fresh weight was noted in control pots treated with 5 mM EDTA and planted with San Sun-33. Similarly, heavy metal accumulation was more in HiSun-33 treated with 50 mg/kg chromium and 5 mM EDTA. In terms of accumulation of heavy metals, HiSun-33 demonstrated better accumulation of the tested heavy metals then SanSun-33, anyhow the growth of SanSun-33 was better than HiSun-33 due to lesser accumulation of heavy metals.

Published: May 2021

Mass mortality of bivalve clams along with some other marine fauna was observed during the month of May 2016, mainly consisting of the clams (Mactra aequisulcata) of family Veneridae surfaced over the Clifton coast. The occurrence of mass mortality of the venerid clams Mactra aequisulcata and other marine life has been studied due to the toxicity of chlorinated hydrocarbons (DDTs, HCHs, hexa chloro benzene (HCB), chlordane, dieldrin (4-chlorophenyl), methanol (TCPMOH) and heptachlor epoxide and polychlorinated biphenyls (PCBs). Significant compositional characteristics of PCBs and DDTs were found in all dead clams and other fauna including fish (Johnius carutta), crabs (Portunus pelagicus), gastropods (Babylonia spirata), bivalves (Anadara antiquata), (Mactra aequisulcata) and the pen shell (Atrina pectinata) from Karachi coast, Pakistan. Mean concentrations (ranges) of organochlorine pesticides (OCPs) in crab (Portunus pelagicus) and fish samples were 1.1 (<0.01-1.5), 0.22 (<0.01-1.1) and 0.14 (<0.01-1.3) /µg/g. Those in, bivalves (Anadara antiquata) and pen shell (Atrina pectinata), clams (Mactra aequisulcata) were 0.09 (<0.02-1.2), 0.22 (<0.02-1.3) /µg and 0.13 (<0.01-0.27), respectively. The heptachlor epoxide was found in highest concentration in clam samples (25.00 ± 30.92) µg/g, (wet weight) however, in bivalves, (2.30 µg/g, (wet weight), which were higher than those in other gastropods. Polychlorinated biphenyls (PCBs) concentrations were also measured in the same samples of gastropods (Babylonia spirata), fish (Johnius carutta), crab (Portunus pelagicus), clams (Mactra aequisulcata), bivalves (Anadara antiquata) and the pen shell (Atrina pectinata) to determine the possible cause of mass mortality. The DDT to metabolites (DDD & DDE) concentration ratios exceeded upto 1.0 in the sessile fauna that is clams (Mactra aequisulcata) and the pen shell (Atrina pectinata) from Karachi coast. These organisms also exhibited dichloro diphenyl trichloroethane (DDT) inputs, whereas dichloro diphenyl trichloroethane (DDD) was found to be in degraded component and PCBs were generally in low concentrations. The concentrations of DDTs were higher than the ERL guidelines in the coastal areas of Karachi, suggesting that there is potential of ecological risk present in the prevailing environment.

Langmuir, Freundlich and Temkin adsorption isotherm models were applied to explain the removal of heavy metal ions by CMSCL biosorbent. Langmuir isotherm model fitted better than other isotherm models. Thermodynamics parameters such as

�H0, �G0 and �S0 showed that the biosorption of Pb (II) and Cd (II) ions onto CMSCL was spontaneous, exothermic and feasible under examined conditions. The occurrence of various functional groups and change in the absorption frequency after metal uptake indicates that complexation was the main mechanism involved in the process of biosorption. Based on the present investigation, it was proved that CMSCL is an effective, alternative and economical biosorbent for the removal of Pb (II) and Cd (II) ions.

Published: May 2021

This study examined the stable carbon isotope13 (8 C) and characterization of sources of organic matter from core samples of sandstones of mid-Siwalik group Dhok Pathan Formation from Surghar- Shingar Range of NW Himalayan foreland Fold-and-Thrust-Belt. These sediments have recorded valuable information regarding the palaeo-vegetation type and paleo-environment/depositional environments. The analytical results of stable carbon isotope range from -24.50 to -28.43% with an average value of -26.56%. These values correspond to C3 vegetation of cool growing season and support the hypothesis of the dominance of C3 biomass in the ecosystem during the late-Miocene in this area. The phytoclasts are  characterized as huminite/vitrinite, derived from terrestrial plants and referred to as type-III kerogen. The fungal attack, scaring and pitting of bacterial activity, biochemical degradation, replacement/diagenetic development of pyrite suggest that these sandstones of Dhok Pathan Formation were deposited under dyoxic conditions and thus these sandstones are primary reduced sandstones.

MoS2 is a layered evolution metal having similar structure to graphene. It has got universal consideration due to its different applications as sensors, energy storage devices, energy adaptation and environmental remediation. The properties of MoS2 and graphene are almost comparable but MoS2 has higher tendency than graphene because it has a low cost, tunable band gap and good visibility for light absorption properties. So, our main focus is to elaborate the up-to-date advances of MoS2 with respect to applications of energy and environment at broad area, for example, applications in HER, Li-ion battery, dye sensitized soar cells and super capacitors. At last the submission of energy and environmental for challenges to design MoS2 are painted. But MoS2 also has some limitations as a good photo catalyst which are discussed in this review article. In this study, we systematically explore the recent researches on transition metal doped MoS2 as photo catalyst for hydrogen evolution by splitting the water

Shock Capturing For High-Order Nodal Spectral Element Methods
Authors: Dzanic Tarik
Published: May 2021

The presence of discontinuities in nonlinear hyperbolic conservation laws is a long-standing challenge in the development of high-order numerical methods. In this talk, I will present an approach to shock capturing for discontinuous spectral element methods which uses invariant domain preservation techniques to construct a low-order scheme devoid of tunable parameters. This technique is then enhanced using a novel point-local entropy residual indicator that is independent of grid spacing and polynomial order, which enables the scheme to recover high-order accuracy in smooth regions and sub-element resolution of discontinuous solutions even at very high orders. The effectiveness of this method is then shown in several numerical test cases that include shock tubes, complex explosion problems, and aeronautical applications.
State of the Art of Ceramic Total Hip Arthroplasty
Authors: Pitto Rocco
Published: May 2021

For centuries, mankind has been trying to find a way to restore the function of compromised limbs. Initially, only external devices were used to split and support. The dramatic advancements achieved in metallurgical, pharmacological, and surgical sciences during the 1950s allowed to safely replace damaged portions of the human body. At this time, which we could refer as the dawn of arthroplasty, several types of joint replacements were developed. The surgical pioneers had to face a number of obstacles during the development of medical devices designed for replacement of the human body. The novel biomaterials needed to be well integrated by the host with a minimal negative response. Examples for adverse tissue responses are bone resorption observed using polyethylene, and inflammatory reactions to metal debris with cobalt chrome alloys. Bioceramics were found to cause minimal tissue reactions, and thus showed excellent biocompatibility; Alumina ceramics in particular have offered a safe solution for bearing surfaces applications in arthroplasty surgery. However, the path to the development of ceramic biotechnology has been a long one. It took three decades to achieve the safety and quality of the current bioceramic composites, which consist of an alumina matrix with finely dispersed zirconia-reinforcing particles. The latest generation of this material, and the principal representative of this category, is the zirconia platelet-toughened alumina (ZPTA) composite. This novel bioceramic, used as a bearing couple for total hip arthroplasty, has shown excellent outcomes in the 20+ years of clinical use due to its high resistance to wear with minimal production of tribological debris, and minimal immune response, which are the prerequisites for long-term survival of joint replacement components.

In this seminar, I will review the development history and analyse the current state-of-the-art of basic science and related clinical research of the contemporary ceramic total hip arthroplasty.

Published: May 2021

Objective: Due to the increase in the elderly population, there is an increase in chronic diseases, infections, depression , and nutritional
problems as well as a decrease in cognitive abilities. This study aimed to investigate the effects of nutritional status, depression
symptoms and demographic characteristics on dementia in the elderly population.
Materials and Methods: This study is a cross-sectional analytic study which took place between first day of April to first day of June
in 2018 in three family health centers selected by simple random sampling from random numbers table in Konya, Turkey. Mini
Nutritional Assessment normal (MNA) and short form (MNA-SF), Geriatric Depression Scale-30 (GDS-30) and the Standardized
Mini-Mental Test (SMMT) was applied to 298 elderly people.
Results: Mild dementia was found in 11.4% (n=34) and, depression symptoms were detected in 5.7% (n=17) of total. MNA-SF showed that
15.8% were under the risk of malnutrition while 2.3% had malnutrition. MNA-SF total score (p=0.004) was significantly higher in males
than in females showing that there was more cognitive impairment in women than men. There was a significant relationship between
the presence of dementia and gender (p=0.048), age groups (p=0.006), education (p<0.001), MNA-SF (p=0.012) and MNA (p=0.002).
Conclusion: The frequency of dementia was higher in women, in low educated, depressive and aged ones and in those with
malnutrition. Regarding dementia, depression and malnutrition in the elderly in primary care; it is important to use well designed
specific scales to these conditions for early diagnosis.

Objective: This study aimed to identify the effect of tocilizumab (TCZ) on clinical outcomes in severe COVID-19 patients.
Material and Methods: We included hospitalized COVID-19 patients with an initial WHO scale ≥4. We matched the patients with
baseline characteristics by using propensity scores. Then, we selected patients with C-reactive protein levels above 30 and showing
an upward trend. We assessed the effect of TCZ in patients on clinical outcomes by using Mann – Whitney U and Chi-square tests.
Results: Of 200 patients who had an initial WHO scale ≥ 4, 42 (21%) were given TCZ in addition to standard of care (SOC). Twentyfive
patients (50%) needed mechanical ventilation (MV) in the TCZ group, compared with 35 (21%) of 158 patients with SOC
(p<0.01). Nineteen (45%) and 37 (23%) patients died in 30 days in these groups, respectively (p <0.01). The secondary infection rate
was significantly higher in the TCZ group (p=0.004). However, no difference was observed in all these parameters in the propensity
score-matched cohort (14 patients in TCZ and 14 in the SOC group) (p=0.45, 0.45, 1.0 respectively).
Conclusions: Tocilizumab does not provide a beneficial effect on MV requirement and mortality in severe COVID-19, and it does not
increase the risk of secondary bacterial infection.
“The Lord Has Rejected You As King Over Israel”: Saul's Deposal from the Throne
Authors: Zimran Yisca
Published: May 2021

This article presents a literary analysis of the extant text of Samuel 15 and argues that Saul's deposal is represented as the result of his lack of recognition of God's authority over him as king. Identifying Saul's behavior as exemplifying one of the ancient views of Israelite monarchy, the article also elucidates the relationship between the king and God reflected in the relevant chapters of the book of Samuel.

The essays in this collection each expand the possibilities of biblical historical-critical scholarship with a focus on textual representations of gendered systems and their implications for understanding the social, political, cultural, and religious contexts in which they were composed. In doing so, they demonstrate the ways in which a gendered historiography can cultivate a more nuanced understanding of power hierarchies in the social reality of ancient Israel.
Conception of 120 mm Kinetic Energy Fragmentating Projectile (PELE) for Leopard 2 Tank. Part 1. Numerical Calculations
Authors: Sadoch Kamil , Magier Mariusz
Published: May 2021

Ammunition used by modern tanks is generally designed to fight strongly armour cladded vehicles and concentrated groups of infantry. Deployment of strongly armour cladded combat vehicles to special missions and asymmetrical conflicts is useful due to their resistance against firing by the infantry. The optimisation of used ammunition and often the development of completely new types is required for efficient use of tanks. The paper presents some studies on selected options of 120 mm kinetic energy fragmentating projectile (PELE) which can be successfully used in urban areas. A review of accessible scientific data was made to analyse possibilities for using some types of materials as components of these projectiles. Projectile’s shell was made of 1045 steel, and the cores were made of aluminium 1050 or polyamide 12.

Isidro Aliau: maestro, inspector y reformista en los orígenes del sistema educativo argentino
Authors: Baretta Mónica
Published: May 2021

In the middle of the 19th century, the progressive consolidation of the American independent states opened new debates related to the need to extend school-based education to the entire population. Within this framework, this article aims to address the figure of Isidro Aliau, a Catalan teacher exiled in Argentina who between 1876 and 1887 held the position of Inspector General of Schools in the province of Santa Fe (Argentine Republic). From there, some of his pedagogical-linguistic contributions will be presented, contributions that have received scarce attention either in the field of the history of education or in the field of language politics. The article focuses on two of his main contributions: the development of a simultaneous teaching method of reading and writing to be used in primary schools, and the presentation of a project to reform the orthography of Spanish language, whose foundation was to simplify writing as a way to facilitate learning. These contributions are interpreted as political interventions in the realm of language, insofar as they represent an attempt to affect the social distribution of the written word, within the framework of an endeavor to expand literacy and democratize education.
