Didáctica de la edad media en educación infantil
Authors: Alonso Jose María Rabal , Gallego Laura martínez
Published: April 2021

Este artículo versa sobre ‘’La época medieval’’. Hemos elegido este tema porque consideramos que es de vital importancia conocer la historia y el pasado de nuestro entorno, de una manera adaptada a Educación infantil, a fin de que puedan interiorizar la noción del tiempo, a la vez que aprenden sobre otras culturas pasadas.

Como menciona Tonda (2001), ‘’comprender un fenómeno significa, también, decir cuando sucedió. Ayudar al niño a conocer su medio para dominarlo, implica también ayudarle a analizar el tiempo’’

Además, se presenta un proyecto dirigido a niños de 5 años de tercero de Educación Infantil en el que se muestra, de manera práctica, la información presente a lo largo de la fundamentación teórica.

Usual and unusual maps: a playful introduction to the basic concepts of cartography in high school
Authors: De Oliveira Érico Anderson , Ferreira Mariana da Silva , De Oliveira Rosália C. Sanábio , Maciel Viviane Moreira
Published: April 2021

This work aims to show the feasibility of introducing basic cartographic concepts in the first year of high school, with simple resources, contributing to the process of knowledge construction by the young person himself by stimulating his curiosity. For this, a theoretical study was made on the theme presented here, then activities were given in the classroom and, later, the diagnosis and debate of the results obtained were carried out. Cartographic literacy, demonstrated in these activities, predisposes the student to work his competence in this form of language, qualifying him/her to make multiple readings of the world through the most disparate cartographic representations possible. Thus, after the didactic sequence used in mediation with the students, in addition to encouraging the reading of maps, the subjects also had the opportunity to create their own fantasy maps. The work was based on David Ausubel's Theory of Significant Learning and the parameters present also in Lev Vygotsky's Historical-Cultural Theory and Henri Wallon's Theory of Development were also used.

Authors: Z.N. Adamyan , A.G. Sayunts , E.A. Khachaturyan , V.M. Aroutiounian
Published: April 2021

Thick-film VOCs sensors based on ruthenated multi-walled carbon nanotubes coated with tin-dioxide nanoparticles (MWCNTs/SnO2) nanocomposite structures are prepared using three methods: hydrothermal synthesis, sol–gel technique and their combined method. It is shown that the optimal conditions for applications as acetone and toluene as well as ethanol and methanol vapors sensors in view of high response and selectivity relative to each other depend on choice of material synthesis method, mass ratio of the nanocomposite components and selected operating temperature. Selective sensitivity to acetone and toluene vapors at 150oC operating temperature MWCNTs/SnO2 are shown sensor structures with the mass ratio of the components 1:4 and 1:24, respectively. The samples with 1:200 mass ratio of the nanocomposite components are shown the selective response to acetone vapor exposure in the range of 200-250oC operating temperatures. The high sensitivity to ethanol and methanol vapors at 200oC operating temperature was revealed for the sensor structures made by different methods with the 1:8, 1:24, 1:50 and 1:66 ratios of the components, respectively.  The results of research works related to the study of thick-film multiwall carbon nanotube–tin oxide nanocomposite sensors of propylene glycol (PG), dimethylformamide (DMF) and formaldehyde (FA) vapors are also presented in this paper. Investigations of response–recovery characteristics in the 50–300oC operating temperature range reveal that the optimal operating temperature for PG, DMF and FA vapor sensors, taking into account both high response and acceptable response and recovery times are about 200 and 220oC, respectively. The dependence of the sensor response on gas concentration is linear in all cases. Minimal propylene glycol, dimethylformamide and formaldehyde gas concentrations, where the perceptible signal was noticed, were 13, 5 and 115 ppm, respectively.

Published: April 2021

La fiebre tifoidea se ha considerado históricamente una enfermedad prevenible, de trascendencia clínica y epidemiológica. Su incidencia disminuyó con el uso de antibióticos y el mejoramiento de las medidas higiénicas. Actualmente, es considerada una entidad atípica, por lo que sus complicaciones son poco comunes. Masculino de once años, sin antecedentes patológicos de importancia, residente en medio urbano al sureste, en México. Después de dos semanas de fiebre y diarrea, el paciente evolucionó con reagudización del dolor abdominal, el cual se sumó a un cuadro de deshidratación e hiperémesis. Fue tratado ambulatoriamente con metronidazol y metamizol, pero sin esquema de rehidratación. Debido a la exacerbación del dolor abdominal, fue llevado al departamento de urgencias de un hospital general, donde evolucionó tórpidamente desencadenando choque séptico y posteriormente falla orgánica múltiple. La fiebre tifoidea, es actualmente una entidad reemergente, cuyas manifestaciones clínicas pueden enmascarar patologías gastrointestinales, retrasando el diagnóstico y tratamiento inmediato, incrementando la probabilidad de complicaciones.
Employment Diversification Patterns in Pakistan: Empirical Assessment Revisited
Authors: Nasir Nazia , Yasmin Fouzia , Safdar Noreen
Published: April 2021

Employment diversification depicts a dynamic socio-economic process where domestic workers widen the range of employment sources. Whereas, the prospect is usually based on a mix of Part-time and Full-time employment. Employment decisions significantly derive from the economic incentives such as wage differentials and the growth rates in different sub-sectors of economic activity. Research at hand summarizes and analyses Employment Diversification Patterns in Pakistan and the motives behind the labor shift. Time series data has been collected from various sources for 1990-2018. The Seemingly unrelated regression model has been applied for empirical estimations. The current analysis of employment pattern diversification concluded that part-time and full-time wages rates have a significant impact on the part and full-time employment in different sub-sectors of economic growth. Variation in wage rates in one sub-sector varies the employment level in different sectors. The estimates elaborated the significant rise in part-time employment these sub-sectors. Moreover, the dynamic interrelation between part-time and full-time employment is examined in the Agriculture, Construction, Electricity, Manufacturing, Wholesale and Retail Trade, Transport, Storage and Communication. These estimates show the quick adjustment of part-time employment within and across the sectors. Policies are needed to enhance labor mobility as one wants to diversify the employment one can do it to enhance the economic productivity.
Extremism & Terrorism: A Political Issue or An Economic One?
Authors: Ali Hina , Khalid Sumaira , Ashraf Iqra , Anwar Naheed
Published: April 2021

Extremism and terrorism have become a serious threat to Pakistan’s security and well-being. Pakistan is situated in an uncomfortable and unfriendly neighborhood and faces an existential challenge from domestic forces of sectional and ethnic militancy and terrorism. These problems started after the 9/11 attacks. The extremists have not only affected the life in tribal areas but have also invaded the well-developed urban cities of Pakistan as well. The lusts for power, religious differences, regional disparities, political instability, illiteracy, foreign involvements, Afghan Jihad of 1975, low socioeconomic indicators, and non-democratic values are a few of the many reasons that have added fuel to the fire of militancy, terrorism, and extremism. More than 75 thousand people in Pakistan have either been killed by terrorist groups or have become a victim of religious militants and extremists. To address these problems Pakistan took a few measures such as the launching of Zarb-e-Azab, amendments to the Unlawful Activities (Prevention) Act, 1967, the establishment of NATGRID, creating awareness about religion, revising Madrassa reforms, etc. All these efforts have solved the problem but only to some extent. There is a dire need for more strict measures not only by the Government but also by the civilians. Together, they need to keep working against these evils because they have eaten up the credibility, economic stability, reputation, well-being and peace of the country.

Studying based on Prophet's Hadith Perspective:
Authors: Karin Nurul , Sumarna Elan
Published: April 2021

This discussion is intended to determine the degree of the Prophet's hadith. in Sunan Ibnu Majah No. 220. This hadith explains the virtues of scholars and the urge to study. This study uses a qualitative approach with a literature study method. Researchers used data collection techniques based on information in literary sources in hadith books, books, journals, seminar results, and discussions with experts relevant to the research theme. The data obtained then the researcher analyzes through qualitative data analysis through the data interpretation process, and the researcher provides an adequate explanation. Based on the results of the discussion, the hadith of the Prophet. in Sunan Ibnu Majah No. 220 is a dhaif hadith because in the hadith there is' illat (defect), a break in sanad, and a defect in the hadith narrator. From several lines of supporting hadith, none of the hadiths can raise the hadith's degree because all of them are weak in nature. From several lines of supporting hadith, none of the hadiths can raise the hadith's degree because all of them are weak in nature. However, according to some scholars, hadith dha'if can be used as hujjah (practiced) only for the basis of the virtue of charity (Fadla'il amal). The implication of this paper is to clarify the law (quality) of the Prophet's hadith. in Sunan Ibnu Majah No. 220. Hadith that has been in Takhrij can be scientifically accounted for its quality, so that it is no longer hesitant to be used as a source of Islamic law after the Al-Qur'an.

Furthermore, EVs have gained substantial interest due to their potential utility for liquid biopsy approaches in cancer.
Analysis of extracellular vesicles by flow cytometry – basics, limitations and prospects
Authors: Spittler Andreas , Görgens Andre
Published: April 2021

Flow cytometry is a well-established technique that classically is used to detect cells and quantify related parameters on the cellular surface, e. g. the expression of surface protein markers. Within the last few years, there also have been considerable advances of using flow cytometry to detect extracellular vesicles (EVs) in the size-range of exosomes and quantify their concentration and surface marker expression in EV-containing samples such as cell culture supernatant or biological fluids. Of note, such analyses of EVs within a size range well beyond <300 nm are still challenging and require a suitable instrumentation and a certain level of expertise to make sure essential controls are included and to ensure that resulting datasets can be interpreted appropriately. After giving a brief, basic introduction into flow cytometry which is essential especially for non-experienced readers in order to understand submicron particle flow cytometry data, we will give a concise overview about current possibilities and methods available in the field.
Mutationen im JAK-STAT-Signalweg und ihre klinischen Konsequenzen
Authors: Ott Nils , Andreani Virginia
Published: April 2021

Der JAK-STAT-Signalweg spielt eine entscheidende Rolle bei der Zytokin-Signalübertragung in den Bereichen Entwicklung, Immunkompetenz und Tumorgenese für fast jeden Zelltyp. Aufgrund der übersichtlichen Mechanismen der Signaltransduktion erscheint dieser Signalweg auf den ersten Blick wenig komplex. Bei genauerer Betrachtung finden sich jedoch viele verschiedene Faktoren, die die JAK- und STAT-Proteine beeinflussen, aber dennoch die Vielfalt der Zellantworten auf die große Anzahl von Zytokinen nicht ausreichend erklären können. Alle beteiligten Moleküle, angefangen vom Zytokin und seinem Rezeptor über die Tyrosinkinasen und die STAT-Moleküle bis hin zu molekularen Feedbackmechanismen (z. B. SOCS- und PIAS-Proteine) und dazugehörigen epigenetischen Veränderungen, können in ihrer Funktion ausfallen und damit die Ursache für die Entstehung vieler verschiedener Krankheiten darstellen. Der JAK-STAT-Signalweg war und ist Gegenstand der Grundlagenforschung und bietet über den Einsatz von JAK-Inhibitoren hinaus ein enormes Potential für die Entwicklung neuer Methoden der personalisierten Medizin und damit der Translation von molekularer Grundlagenforschung in die klinische Praxis.
Inflammasom Signaling und chronische Entzündungsreaktionen
Authors: Uchima Miki , Latz Eicke
Published: April 2021

Inflammasome sind Multiproteinkomplexe, die typischerweise aus drei Proteinentitäten – einem Sensor, einem Adaptor und Caspase 1 – bestehen. Sie werden als Antwort auf die Erkennung von Pathogen-assoziierten molekularen Strukturen (PAMPs) oder Gefahren-assoziierten molekularen Strukturen (DAMPs) gebildet. Eine Schlüsselrolle im Inflammasom-Signalweg spielt dabei das Zymogen Pro-Caspase 1, das zunächst selbst durch Autoprozessierung aktiviert werden muss. Aktive Caspase 1 prozessiert die Vorstufen der pro-inflammatorischen Interleukine (IL) IL-1beta (IL-1β) und IL-18, die daraufhin sekretiert werden. Caspase 1 schneidet zusätzlich Gasdermin D proteolytisch, was eine spezielle, pro-inflammatorische Form des Zelltods – Pyroptose – induziert. Durch die Sekretion der pro-inflammatorischen Interleukine und Pyroptose wird eine starke Entzündungsreaktion ausgelöst. Das Ausmaß einer Inflammasom-vermittelten chronischen Entzündungsreaktion wird bei Patienten mit „gain-of-function“-Mutationen deutlich, bei denen es zu einer Überaktivierung der Inflammasom-Sensoren kommt. Diverse Mutationen in Genen, die einzelne Sensoren der Inflammasome kodieren, lösen chronische Entzündungs- und Autoimmunerkrankungen aus, die unbehandelt tödlich verlaufen können. Viele Studien haben uns gezeigt, wie essentiell präzise Regulations- und Aktivierungsmechanismen sind, um eine effektive Bekämpfung von Pathogenen zu ermöglichen und gleichzeitig unkontrollierte und damit schädliche Entzündungsreaktionen zu verhindern. Dieser Review-Artikel fasst die allgemein anerkannten Konzepte der Inflammasomforschung zusammen und gibt Einblicke in die Aktivierungsprozesse von Inflammasome-Sensoren und die Bildung von Inflammasom-Komplexen.

PSYCHOLOGICAL FACTORS AND INVESTMENT DECISIONS IN THE NIGERIA CAPITAL MARKET
Authors: Evbayiro-Osagie Esther Ikavbo , Chijuka Michael Ify
Published: April 2021

This study examines Behavioral Factors and Investment Decision Making in the Nigerian Stock Exchange (NSE). Thus, the research question is what are the psychological factors affecting investment decisions in the Nigerian capital market. A structured questionnaire was used in collecting data and it was able to collect data from 75 investors with the application of a convenient sampling method. Using overconfidence bias, availability bias, conservatism, and herding effect to define the most important behavioral element affecting investment decision making by investors in the Nigerian. Multiple regression analysis was used as the key methodological method for evaluating the research hypothesis, whereas the internal consistency of the questionnaire calculated from Cronbach's alpha on all variables showed values greater than 0.7 with a sufficient level of reliability. The primary beneficiary group would be the buyers on the stock market who would be educated enough about the effect of their own behavioral influences on their stock market decision making. The knowledge would be useful in making optimal investment decisions and avoiding unfavorable decisions to increase their resources. In turn, it will be helpful to policymakers and stock market regulators to help them understand the position of behavioral influences inherited in consumer decision-making and that may be associated with the need for stock market brokers to update their customer's trading practices to a higher level. The findings of this study suggest that overconfidence, availability bias, and herding impact demonstrated a positive significant relationship with NSE investment decision-making except conservatism which showed a negative relationship with investment decision-making but at 0.01 levels statistically significant. On the basis of the results, it can be generalized that the most prevalent factors affecting investor investment decision taking in NSE are overconfidence, availability bias, and herding influence.

Authors: Barnut Catalin Florin
Published: April 2021

The aim of the paper is to assess the effects of the coronavirus pandemic (COVID – 19) on two stock market indices: BET index for Bucharest Stock Exchange and WIG20 index for Warsaw Stock Exchange. The negative effects of the pandemic have had an influence on the performance of the stock markets since its debut. Many companies as well as sectors have ceased their activity during the outbreak, causing devastating financial losses worldwide. By comparing indices evolution during 2020 using the data available on the stock markets’ websites, as well as analyzing in part the companies that make up the indices portfolio, we will try to present the sectors most affected by the pandemic as well as their evolution during the analysis period. The results of this research can be a starting point for future empirical analysis on the long-term effects of the pandemic on stock markets’ performance for Romania and Poland. The results could be a source of information for state institutions, companies, investors, analysts but also representatives of the medical sector (responsible for crisis management) - in order to observe the severity and magnitude of the negative effects of the coronavirus pandemic on the financial markets and also help develop and ensue their long-term sustainable growth.
Magical Thinking: Conversation with Geoffrey Batchen
Authors: Kanicki Witold , Batchen Geoffrey
Published: April 2021

His long-standing interest in the history of early photography makes Geoffrey Batchen the appropriate speaker to discuss the question of photographic magic. Therefore, our conversation oscillates between magic and realism, but also other antonyms within the medium: negative and positive, analogue and digital. Taking in consideration all these oppositional notions, Batchen suggests that theoreticians “need to acknowledge and embrace photography’s abstractions and contradictions”. Different contradictions within photography’s theory and history became pivotal in our conversation. We also discussed the indexicality of digital images. According to Batchen, the negative/positive system of traditional photography can be compared with the binary code of digital images, which “is therefore based on the same oppositional logic, the same interplay of one and its other, that generated the analogue photograph.” Moreover, digitality does not eliminate the magic character of the contemporary photographs; in this context, Batchen mentions the capacity of instant transmission of snapshots from one place of Earth to another. In conclusion, Batchen reveals some details of his upcoming book Negative/Positive: A History of Photography.

Magic in the Dark
Authors: Bush Lewis
Published: April 2021

Throughout its history, photography has been viewed as something imbued with magical qualities, able to detect the supernatural, or capturing a part of the identity of those it depicts. Even in more enlightened times, these beliefs linger, and security personnel and police officers often ascribe to photography an ability to capture and record dangerous levels of detail. In response to a series of encounters with such personnel, I began to travel to locations around the city of London equipped with a camera obscura, which I would then use to draw highly sensitive locations in meticulous detail, inviting a response. The aim was to draw these same security personnel and police officers into a discussion about their fears about photography, and to illustrate that the abilities we often associate with photography are not at all unique to it.

Darpeix, member of the historical and archaeological society of Perigord, to a distant shamanic and Neolithic antiquity). They are masks adorned with skins of animals, vegetables, and straw, surrounded by bells and bones, often crowned with horns and pieces of wood. Thus arises the wild man within modern paganism to symbolize the rebirth of nature emerging from winter. The figures are essentially ambiguous, at the crossroads of nature and culture. The masks always speak of the mysteries of existence: in traditional societies, they were or still are the figures of ancestors and spirits of the dead, that of protective or evil spirits.
Light of the Soul
Authors: Liszi Renáta
Published: April 2021

Liszi’s work creates visual signs derived from spherical forms of sacred geometry on photograms. Her camera-less images focus on Oneness – universe and us, based on the Light of the Soul. She works with her voice that creates ripples in water. Her experiments began with exploring the Bija mantras Aum, RaMaDaSa, and lastly SaTaNaMa that describes the eternal circle of life: birth, life, death, rebirth. Her experimentation led from mantra vibration in still water (life symbol) to light vibration (life symbol) as information carrier. The fundamental connection between water waves and light waves inspired extra stimulus in her experimental work. Quantity of water, shapes of bowls, colours of light, angles of light – are all various avenues of exploration. The sacred geometric angles and the variety of the wavelengths of electromagnetic vibrations created intimate, meditative space that gives birth to these unique photograms. Her initial experiments were with B&W positive papers then 5 × 4″ and 10 × 8″ B&W negative films. The orthochromatic negatives allowed her to work in safelight, which led to the creation of enlarged images mixed with other wavelengths. Thus, monochrome was reborn through colour.
Exorcism in Camera: An Experiment in Ontology (1999): from The Karen Smith Archive
Authors: Halford Victoria
Published: April 2021

Karen Smith (1966–2017) had long been interested in altered states of consciousness. In seeking help with her own psychiatric illness, she came across Agrippa’s works on occult philosophy and the use of spoken-word formulas for entering and exiting differential states of being. These steps over the psychic threshold are known as adorcism and exorcism – the summoning and banishing of demons or spirits. Over the course of a week in 1999, she decided to try out some of Agrippa’s techniques. She chose to be possessed and then dispossessed by the seven spirits associated with the planets of classical antiquity. She documented one ritual per day. For each action, she used the same devices – a bathtub filled with water, a lamp and an audio cassette player with a tape featuring incantations pre-recorded by a ceremonial magician. Published here are the results of these ontological experiments.
Korean Shamanism: Betwixt & Between
Authors: Schlottmann Dirk
Published: April 2021

The project shows the Korean shamans of the North Korean Hwanghaedo tradition in liminal moments. These are periods in which they experience ecstasy and trance because they seek contact with spiritual entities or are possessed by gods, spirits, or ancestors. They are in an intermediate position “betwixt and between” that is very difficult to describe and is in fact experienced in a manifold of ways. The shamans that came as refugees after the Korea war imported the Hwanghaedo tradition from North Korea to South Korea. The ecstatic and wild ritual practice survived in South Korea because many refugees perceived this tradition as part of their culture and identity. Among the several regional shamanism traditions practiced in South Korea today, Hwanghaedo shamanism is widely acknowledged as the one that retains the magio-religious traits that are the spiritual essence of Korean shamanism’s belief and practice.
Photogenic Intensions
Authors: Burleigh Peter
Published: April 2021

What is a photograph? What a spurious, redundant start! After all, a photograph is clearly an image, a technical image of something. What a photograph is – such a stupid question! Yet, the casual announcement of the photograph as signification relies on an a priori truth that orients our thinking, our identities, our institutions. For it is “in terms of this self-apparent image of thought that everybody knows and is presumed to know what it means to think.” Collaging Deleuze and Bergson, intuition teaches us that an image is a nexus of force in itself, or as Anne Sauvagnargues suggests, what is crucial to images is how they cut into the world. As real enfoldings of the virtual and actual, photographs are the territories of a multiplicity of sensations – a genesis, the real actual of a diagrammatic structuring of the world in registers of time and space. Roger Fenton’s The Queen’s Target made at Queen Victoria’s opening of the first Rifle Association in 1860 is an entry point to thinking deeper signalisation in photographs. While the 3-D work by Andreas Angelidakis indicates photogenetic zones of intensity, temporal dislodgment, and the event of photogenesis actualized in physical form.

How Does Photography Appear to Appear?
Authors: Hillman John
Published: April 2021

Photography shares little with the logic of simulation and simulacrum, instead it facilitates a dimension within which people and objects we photograph emerge from an impossible frame. Its intrigue resides in the palpable sense of impossibility that photographs render visible to us. This sleight of hand obfuscates the question of how appearance appears. In Finders Keepers, Dutch photographer Laura Chen works with imagery sourced from undeveloped films purchased from eBay and car-boot sales. When Chen develops the films, the real of someone else’s reality is transformed into art. Left undeveloped, these images occupy nowhere in particular, but Chen makes appearances fill in a void and poses a question which is not one of “why” but of “where” are images? Furthermore, in seeking out meanings, the magic of photography is understood through the misdirection of illusion and appearance. What is more useful is to ask how photography appears to appear?

Invisible Presence of the Past: Hauntology of Photography
Authors: Michałowska Marianna
Published: April 2021

Photography has been associated with the specter, spirit, and the apparition ever since the theory of photography first emerged. André Bazin and Edgar Morin saw the spectral features of photography as the basis for phenomenological interpretation. However, the most creative exposition of ghosts in photography is linked to Jacques Derrida’s concept of hauntology. Nowadays, hauntology is often cited in relation to nostalgia – longing for “the lost futures”. However, when Derrida wrote Specters of Marx in 1993, he was interested in the ontological repetition of ideas through history. Photographs created by two contemporary Polish photographers (Michał Grochowiak and Nicolas Grospierre) are an excellent illustration of the French philosopher’s thoughts, as their works focus on the same theme – architecture of the socialist era. The recurring specter of the past manifests itself through it. Grochowiak’s photographs from the Breath series (2010) depict the interior of the Palace of Culture and Science in Warsaw – fragments of a monumental memorial from the socialist era. In turn, Grospierre’s series of photographs titled K-Pool and company (2011) documents modernist buildings in the post-Soviet republics. In the article, the reference to hauntology allows me to discuss photography as a carrier of eeriness as well as an invisible tool of disclosure. What’s more, it seems that hauntology may explain the role of photography in discussing the political and social contexts of the past.

The Mystics and Magic of Latent Space: Becoming the Unseen
Authors: Seberger John S. , Slaughter Aubrey
Published: April 2021

Bridging concerns from human-computer interaction (HCI) and media studies, this essay theorizes deepfake images in terms of their phenomenological implications: the extent to which they enfold the human viewer in a world of the otherwise unseen. Drawing on comparative phenomenology of Vilém Flusser and Louis Bec, we focus on variational autoencoders (VAEs). We contend that the processes underlying deepfake image construction, as much as deepfake images themselves, evidence a parallel, prosthetic, and computational phenomenology: a study of “that which appears” to a computer, and which appears secondarily to a user-human as image. We use the example of VAEs to argue for the emergence of a second-order, received phenomenology of the augmented human as we reside in an increasingly computational world.
