Bertholletia excelsa, conocida como castaña, es una especie forestal de gran importancia económica y ecológica a nivel nacional e internacional, actualmente su presencia en los bosques de Madre de Dios se ve amenazada por actividades antropogénicas como la deforestación, la degradación de suelos y la disminución de las poblaciones naturales. Considerando dicha problemática, en el presente trabajo se realizó la micropropagación in vitro de esta especie como tecnología estratégica para su conservación y producción a gran escala. Para la micropropagación in vitro se probaron 6 tratamientos en base a factores como 2 concentraciones de Woody Plant Medium (WPM) al 50 y 100% y 3 concentraciones de sucrosa (30, 40 y 50 g/L) obteniendo como resultados que el mejor protocolo corresponde a WPM al 50% con 30 g/L de sucrosa, dando un crecimiento de 2.37 cm, 2.73 nudos y 1.60 hojas de promedio. Finalmente indicamos que el medio con WPM 50% y 30 g/L de sucrosa es eficiente para el cultivo de tejidos vegetales de esta valiosa especie forestal.

A Non-Existent Place: The Importance of Fantasy Settings
In fantasy literature, the setting is as important to the story as are character and plot. This article demonstrates how topofocal (place-focused) perspectives yield valuable insights into various fantasy texts. The examples include discussions on how the nature/culture relationship is tied to the ideological centre in Charles de Lint’s Newford stories; how a careful examination of Sauron’s land in J.R.R. Tolkien’s The Lord of the Rings reveals how the text views the nature of evil; and how the structure of the land develops along with the stories in the Mythago Wood novels by Robert Holdstock. In a genre where there are no limits to the shape a setting can take, the central question must be: Why is it shaped the way it is?

The Banishment and Return of Venus: Skogekär Bergbo’s Wenerid as Occasional Poetry
This article deals with the Swedish sonnet sequence Wenerid, written by the pseudonym Skogekär Bergbo in the tradition of Petrarch. It was published in 1680 but, according to the author, written ”more than thirty years ago”, during the reign of Queen Christina. At her court, expectations that the young queen would soon marry found expression for instance in court ballets. Skogekär Bergbo was possibly the author of the Swedish texts of a couple of such ballets. Similarly, his Wenerid could be interpreted as part of the homage paid at court to the power of love. Queen Christina decided, however, not to marry, and literary tributes to Venus were no longer desirable at her court. This could perhaps explain why Wenerid was not published during her reign.1680 was the year of the marriage between King Charles XI and the Danish princess Ulrika Eleonora. It seems plausible to relate the publication of Wenerid in 1680 to the wedding of the royal couple and the coronation of the new queen. But the book bears no dedication, and it cannot, as has been proposed, be regarded as occasional poetry for the royal festivities. It is, however, possible that the poet saw an opportunity of bringing to the fore an aristocratic culture which had flourished in the days of Queen Christina. One of the manifestations of this culture was courtly Petrarchism and the cult of the goddess of love. 1680, the year of the royal wedding, was a favourable time for the return of Venus, and of Wenerid.

Friendship on Parnassus: Occasional Poetry in Swedish Dissertations of the 1720s
In early modern Sweden many thousands of academic dissertations were printed. These usually contained a large number of paratexts, including eloquent homages addressing patrons as well as respondents. Not much scholarly attention has been paid to these texts; the present article aims at exemplifying how social interdependence and mutual solidarity in the early 18th century are expressed in the praise directed to the respondents. Students in Sweden were members of so-called ”student nations” based on the students’ geographical origin. It is shown that the authors of the poems or eloquent prose pieces included in the dissertations were usually friends belonging to the same student organisation or the respondent’s own pupil, who paid homage to his tutor. At the centre of the article stands the future vicar and inventor Nils Brelin (1690–1753). Analyses of his Swedish-language poetry and his painting of a student’s progress towards the Temple of Honour – commissioned by Brelin’s student nation – are used to elucidate the techniques and aesthetics informing the period’s academic epideictic writing.
Johannes Edfelts hand

Published: February 2023

The Hand of Johannes Edfelt: The Study of a Motif
This is a study of the hand as a frequent motif in the poetry of Johannes Edfelt (1904–1997), one of the leading Swedish poets of his generation and a member of the Swedish Academy. The hand motif in Edfelt´s poetry sometimes tends to be a vital theme and can be interpreted as a symbol, though flexible and ambiguous. From a rhetorical point of view it is more often than not handled as a synecdoche, more specifically as a pars pro toto referring to fate, the whole of mankind, or life itself. From a hermeneutic point of view it can manifest itself as a magic hand; as such, its origin is not merely biblical, but obviously also deeply connected to primitive art and especially to ancient petroglyphs and cave paintings, which began to inspire modernist writers and artists all around Europe in the 1920’s. Edfelt was devoted to the hand motif over the course of more than seven decades, from his first collection of poetry in 1923, to his last in 1996.
As limitações cognitivas nos levam a desqualificar o saber alheio
Authors: Agrela Fabiano de Abreu 
Published: February 2023

Uma pessoa acometida por qualquer disfunção cerebral, que afete de forma direta a região frontotemporal do cérebro, tem dificuldade em discernir, interpretar e arquivar um novo conhecimento e/ou ideia, não apenas pela "atrofia" nestas regiões, ou a não eficiência na comunicação da circuitaria neural. Mas por haver um vício mental, já instalado da recompensa, o cérebro opta pelas memórias já cristalizadas, apreendidas. Este fato dá-se, não apenas pela economia de energia cerebral, mas por utilizarem essa rota cognitiva de forma a satisfazer e proteger o narcisismo primário, diante daquilo que conforta e por irem de encontro ao seu raciocínio e ideias primárias. Podemos portanto referir que essas memórias foram armazenadas, assim como as modeladas pela experiência a favor das reações fisiológicas prazerosas do próprio indivíduo. Quando este se coloca desta forma perante o que lhe podem parecer ideias de confronto, exatamente por não conseguirem sair da bolha do que lhe é confortável, encontram-se em terreno infértil, impossível de gerar novos pensamentos obviamente pela dificuldade em estabelecer novas experiências através de quebra de paradigmas. Além disto, há uma tendência em desqualificar o saber alheio, em retirar lhe valor e importância especialmente quando este fere o íntimo e quando este não é compreendido. Há uma aversão ao que se suplanta e uma inabilidade para fazer o curso contrário e tentar apreender e somar conhecimento.

Nowadays, technology occupies a preeminent place in different social spheres. In the educational world, technology and, more specifically, virtual reality can respond to the diversity of students present in the classroom. In this line, the aim of this study is to explore the application of immersive virtual reality to promote communication and social interaction in students with ASD. For this purpose, an immersive virtual reality (IVR) environment has been designed in a classroom where participants are presented with different learning situations in the classroom. The sample consisted of three participants, with whom a pilot study was developed with interaction and social communication activities with the virtual teacher and the NAO robot. The IVR glasses were used for data collection and a questionnaire was designed ad hoc. The results show that the students' attention was attracted to the elements that make up the IVR environment. Likewise, a good acceptance of the IVR device and satisfactory interactions have been observed. In conclusion, it can be stated that the RVI environment has provided realism and remarkable possibilities for interaction

Computer Literacy is a reality in current educational legislation. Within the STEAM competence approach, music education and the development of Computational Thinking (CT) are located in this discipline. In this work, unplugged musical activities are designed based on the Bebras challenges, and their effectiveness is evaluated in terms of CT development in students. A quasi-experimental study was carried out with pre-post test measures in a group of 220 Primary School students (experimental, N = 170; control, N = 50). The experimental group performed three blocks of unplugged musical activities. Computational Thinking Test using Bebras Problems (Lockwood and Moone, 2018) was used as an instrument. Variables of gender, course, environment and academic ability were taken into account. The results show a significant increase in CT in the experimental group at a general level and in the Bebras activities of medium and advanced levels of difficulty. Schoolchildren from the rural context showed higher scores in CT development compared to the urban one. No significant differences are observed in the rest of the variables. Finally, a higher level of correct answers was observed in "easy" activities, greater completion of "medium" activities and a decrease in both in "advanced" activities.

Optional Narratives and Supplemental Storytelling in Behaviour Interactive’s Dead By Daylight Steven Greenwood
Authors: Greenwood Steven 
Published: February 2023

This written analysis and the videographic essay it accompanies explore the relationship between narrative and gameplay in Dead by Daylight (DBD). The term “ludonarrative dissonance” has become very popular in video game discourse, referring to situations where the gameplay and narrative of a game seem to be at odds: the story tells you one thing, while the actual gameplay mechanics ask you to do something that doesn’t logically fit with that story. I want to explore how Dead by Daylight creates the opposite phenomenon of ludonarrative harmony, where every gameplay input or choice not only fits within the narrative but actually serves a crucial role in telling it.
Match-based, short-form games like DBD often struggle with ludonarrative dissonance. It’s really hard to tell a cohesive, consistent story in a game with short, standalone, multiplayer matches where each match begins and ends in the same place. DBD is a compelling example of a game that manages to find a strong narrative function for its cyclical matchmaking structure. The last section of this analysis makes a case for why this phenomenon is particularly relevant to the horror genre. DBD takes a style of game where narrative is often seen as secondary or optional to the main experience of gameplay and makes a case for the centrality of narrative to the game. I tie this into a similar discussion of horror, exploring how people often see the plots of horror movies as thin excuses for the “real” entertainment, and how these assumptions miss out on the importance of narrative to even horror films whose narrative seems supplementary.
Impact of COVID 19 on Digital Marketing: A Systematic Study on Sub Saharan African
Authors: Dadzie Isaac 
Published: February 2023

The spread of the COVID-19 pandemic has had massive impacts on digital marketing, notably in Sub-Saharan Africa, which had been the preferred method of marketing in recent years. The term "Sub-Saharan Africa" is used to describe the African countries south of the Sahara Desert. This includes the eco-region of the Sahel, which lies between the Sahara and the African tropical and forest savannah zones, and the island states off Africa's western and eastern borders. South Africa, Sudan, Nigeria, Kenya, and Angola are just a few of the 48 countries that make up Sub-Saharan Africa. This study seeks to determine the impact of COVID 19 on digital marketing in Sub-Saharan Africa. Utilizing systematic review and, especially, the quick review approach, this objective was accomplished. The study concluded that COVID 19 had both positive and negative impacts on digital marketing in Sub-Saharan Africa. Sales, advertising, and promotion via digital channels have increased, which is a positive development. As a result of the lockdown and the corona virus epidemic, people are more likely to conduct business on the internet. Enhanced internet marketing has helped firms in Sub-Saharan Africa expand their clientele, revenue, and profits.
Unfortunately, many digital marketing firms' reputations were damaged because some users abused their access to various online services by engaging in fraudulent activities during the epidemic. Ad, marketing, promotional, and media spending have all been adjusted as a result of the global COVID-19 epidemic. The study concluded and suggested that Sub-Saharan businesses and government institutions must be courteous, employ digital marketing, and respond to consumers during cultural events like the COVID-19 pandemic. To keep consumers, brands must fix the problem while being positive. Adjusting marketing campaign and content timings, advertising language and visuals, and being aware of customers' growing concern may do this. Under the global pandemic, Sub-Saharan African (SSA) firms must rely more on digital sales or e-commerce to flourish.

Aim: This study was aimed to find out the mismanagement of infantile masturbation and the outcome of the cases who were treated with anti-epileptic drugs.
Study Design: Retrospective.
Place and Duration of Study: This study was conducted at outpatient department of Rehabilitation and Neurology unit of Dr. M R Khan Shishu Hospital and Institute of Child Health, Dhaka Bangladesh, between 2013-2022.
Methods: Data were collected from records which included socio-demographic data and clinical features of masturbation in children. Data related to treatment was also collected and their outcome was observed.
Results: Among 50 patients, majority (74%) had age of onset between 12-36 months of age. Mean age was 43±26 months, the range was between 4 months to 84 months. Female were predominant (60%). Most of the children came from urban area (86%) and belong to nuclear family (78%). They presented with stereotype movement of variable duration and there was no alteration of consciousness. Prone positioning was more frequent than prone to supine position (78% Vs 18%). There was no laboratory and EEG abnormalities among the cases. Thirty two percent patients were treated with anti-epileptic drugs from outside and among them 2 (12%) was given sodium valproate and rest 14 (88%) were treated with phenobarbitone. But there was no clinical improvement in these cases.
Conclusion: Use of anti-epileptic drugs was not associated with any clinical improvement in children with infantile masturbation.

Background: An important sign of congenital heart disease (CHD), myocardial dysfunction and foetal congestive cardiac failure is cardiomegaly, which is detected using the assessment of the cardiothoracic (CT) ratio.
Objective: To evaluate the foetal CT ratio and its relationship with gestational age in the second half of pregnancy, and produce nomograms for the foetal CT ratio.
Subjects and Methods: This descriptive, cross‐sectional study enrolled women with a normal pregnancy in their second and third trimesters at the two tertiary health facilities, one secondary facility and one radiodiagnostic facility in Bayelsa State, Nigeria. The study was conducted from April–December 2022. Pearson's correlation and logistic regression analyses were used to assess the relationship and correlation between the CT ratio, gestational age, and estimated foetal weight. The p<0.05 at 95%CI level of significance was set.
Results: The mean bi-parietal diameter estimated foetal weight and CT diameter ratio was 66.5 ± 18.3 mm, 1.24 ± 0.87 kg and 0.46 ± 0.02 cm respectively. The foetal CT ratio correlates very strongly with estimated gestational age (ɼ = 0.98; p – 0.001), bi-parietal diameter (ɼ = 0.96; p – 0.001), estimated foetal weight (ɼ = 0.92; p – 0.001), Maternal age (ɼ = 0.36; p – 0.001), maternal weight (ɼ = 0.19; p – 0.001) and maternal height (ɼ = 0.20; p – 0.001).
Conclusion: We have demonstrated that there does exist a very strong correlation between the foetal cardiothoracic ratio and the foetal gestational age, biparietal diameter and foetal weight, which slightly, but steadily increased throughout pregnancy.
