Efficient synthesis of polyfunctionalized carbazoles and pyrrolo[3,4-c]carbazoles via domino Diels–Alder reaction
Authors: Fang Ren-Jie , Yan Chen , Sun Jing , Han Ying , Yan Chao-Guo
Published: September 2021

The p-TsOH-catalyzed Diels–Alder reaction of 3-(indol-3-yl)maleimides with chalcone in toluene at 60 °C afforded two diastereoisomers of tetrahydropyrrolo[3,4-c]carbazoles, which can be dehydrogenated by DDQ oxidation in acetonitrile at room temperature to give the aromatized pyrrolo[3,4-c]carbazoles in high yields. On the other hand, the one-pot reaction of 3-(indol-3-yl)-1,3-diphenylpropan-1-ones with chalcones or benzylideneacetone in acetonitrile in the presence of p-TsOH and DDQ resulted in polyfunctionalized carbazoles in satisfactory yields. The reaction mechanism included the DDQ oxidative dehydrogenation of 3-(indol-3-yl)-1,3-diphenylpropan-1-ones to the corresponding 3-vinylindoles, their acid-catalyzed Diels–Alder reaction and sequential aromatization process.

Published: September 2021

This research aims to know the effect of adopting IFRS 9 on the relevance of the value
of the accounting information of the companies in the Iraqi Stock Exchange. Researchers
relied on analyzing the financial statements of 10 listed companies for years 2016 – 2019.
Researchers used the Ohlson price model to test the relationship between accounting
information and value relevance. The research indicated that there is a significant relationship
between the adoption of IFRS 9 and the relevance of the value of the earnings and the book
value, but the earnings information is more relevance than the book value information, it is
due to the interest of investors in the income statement in making investment decisions.

NÃO DEIXE MORRER MINHA ESPERANÇA
Authors: Alves de Oliveira Reis Sônia Maria , Gomes Marques Tatyanne , Souza Cunha Júnior Adenilson
Published: September 2021

Este texto tem por finalidade apresentar um pouco da história do Movimento de Educação de Base de Iniciativa Católica (MEBIC), identificando o contexto sócio-político, abordagens teóricas e práticas pedagógicas. O projeto parte do seguinte pressuposto: “Alfabetizar é conscientizar-se, é aprender a escrever a vida, como autor e como testemunha da história, é biografar-se, é existenciar-se, é historicizar-se” (FREIRE, 1989). Concebe a alfabetização não apenas como a aquisição do domínio da leitura e da escrita, mas como o desenvolvimento da capacidade de usar essas habilidades no âmbito pessoal e coletivo. Os dados empíricos analisados neste artigo são resultados de diferentes pesquisas que compõem o Núcleo de Estudos Pesquisa e Extensão Educacional Paulo Freire (NEPE-CNPq). A compreensão dos dados fundamenta-se nos pressupostos da abordagem qualitativa. Do ponto de vista técnico-metodológico, utilizou-se análise documental, observação e entrevistas, visando apresentar os perfis e os saberes construídos na-pela experiência na EJA. Os/as educandos/as do MEBIC têm um bom desempenho na oralidade, mas muita dificuldade e medo de escrever; enfatizam o tempo todo que não sabem escrever, que seu texto tem muitos erros e parecem morrer de vergonha no momento de expor seus conhecimentos acerca da língua escrita. Além disso, esperam encontrar escolas que sejam acolhedoras e cuja organização do trabalho pedagógico seja acessível a eles e satisfaça as necessidades do/a trabalhador/a. Esperam ainda que a escola possa educá-los/as, ou seja, emancipá-los/as pelo saber, integrar e praticar uma política ativa de justiça social e cognitiva em benefício, principalmente, dos que são pouco escolarizados/as.
MEMÓRIA DAS REITORAS SOBRE GESTÃO DEMOCRÁTICA UNIVERSITÁRIA
Authors: Silva Josias Benevides
Published: September 2021

O artigo tem como objetivo analisar a memória coletiva de reitoras, no que se refere à gestão democrática e participativa, à luz da teoria de Paulo Freire e outros autores que discutem temáticas relacionadas ao poder e gestão democrática da educação. A metodologia é de natureza qualitativa, com pesquisa bibliográfica e de campo, entrevistas semiestruturadas e análise de conteúdo. Os resultados deste estudo revelam que, da mesma forma que Paulo Freire entende processos democráticos e participativos, as mulheres que foram reitoras no Estado da Bahia percebe que não se pode falar em democracia e participação sem a inclusão do gênero feminino nas relações de poder.

O presente artigo tem como objetivo apresentar o ensino de História e Geografia em uma unidade escolar de Educação de Jovens e Adultos no município de Araraquara, interior do Estado de São Paulo. As observações relatadas nesse trabalho são fruto do estágio da licenciatura em Ciências Sociais realizado no segundo semestre de 2019. Após contextualização do ambiente escolar, expomos algumas das particularidades observadas nas aulas das referidas disciplinas, bem como seu conteúdo e a didática. Notou-se que aspectos da educação “bancária” (FREIRE, 2013) e da falta de autonomia e planejamento das aulas se fazem presentes nas práticas de ensino presenciadas.
DIALOGICIDADE E AFETIVIDADE COMO PRINCÍPIOS PARA UMA EDUCAÇÃO LIBERTADORA NA EJA
Authors: Fernandes Marcos Vinicius Reis , Bandeira Glaucio Martins da Silva , Alvarenga Marcia Soares de
Published: September 2021

O presente trabalho tem por objetivo analisar as categorias dialogicidade e afetividade como aspectos necessários ao processo pedagógico na modalidade de Educação de Jovens e Adultos (EJA). Recorreu-se de estudos bibliográficos de obras de Paulo Freire para o diálogo das categorias em análise.  Desse modo, compreende-se que as categorias em referência estão diretamente relacionadas a um processo de ensino-aprendizagem voltado para emancipação humana dos estudantes trabalhadores. Conclui-se, portanto, que uma educação libertadora para a autolibertação destes sujeitos deve ser pautada na valorização de saberes intra e extraescolares que permeiam nas relações dialógicas e afetivas.

Comet C/2015 ER61 (PanSTARRS) is a long-period Oort cloud comet whose favorable approach to the inner parts of the solar system in 2017 April–May enabled us to characterize its primary volatile composition using the iSHELL spectrograph mounted on the 3 m NASA Infrared Telescope Facility (IRTF) on Maunakea, Hawaii. We used three iSHELL settings (covering ∼2.8–5.2 μm) to sample fluorescent emissions from

The relative abundances of these volatile species remained consistent within uncertainties during our pre-perihelion observations but tended to decrease during our post-perihelion observations (with the exception of

OH and HCN). The short-timescale variability in the production rates of these volatiles could be due to diurnal effects (over the course of the rotation of the nucleus) and/or the effect of its outburst. The decrease in the production rates and hence the mixing ratios in some volatiles in post-perihelion dates could be due to the presence of seasonal effects in ER61.
Radioactive Planet Formation
Authors: Adams Fred C.
Published: September 2021

Young stellar objects are observed to have large X-ray fluxes and are thought to produce commensurate luminosities in energetic particles (cosmic rays). This particle radiation, in turn, can synthesize short-lived radioactive nuclei through spallation. With a focus on 26Al, this paper estimates the expected abundances of radioactive nuclei produced by spallation during the epoch of planet formation. In this model, cosmic rays are accelerated near the inner truncation radii of circumstellar disks, r
X ≈ 0.1 au, where intense magnetic activity takes place. For planets forming in this region, radioactive abundances can be enhanced over the values inferred for the early solar system (from meteoritic measurements) by factors of ∼10−20. These short-lived radioactive nuclei influence the process of planet formation and the properties of planets in several ways. The minimum size required for planetesimals to become fully molten decreases with increasing levels of radioactive enrichment, and such melting leads to loss of volatile components, including water. Planets produced with an enhanced radioactive inventory have significant internal luminosity, which can be comparable to that provided by the host star; this additional heating affects both atmospheric mass loss and chemical composition. Finally, the habitable zone of red dwarf stars is coincident with the magnetic reconnection region, so that planets forming at those locations will experience maximum exposure to particle radiation and subsequent depletion of volatiles.

The Simons Observatory is a ground-based cosmic microwave background experiment that consists of three 0.4 m small-aperture telescopes and one 6 m Large Aperture Telescope, located at an elevation of 5300 m on Cerro Toco in Chile. The Simons Observatory Large Aperture Telescope Receiver (LATR) is the cryogenic camera that will be coupled to the Large Aperture Telescope. The resulting instrument will produce arcminute-resolution millimeter-wave maps of half the sky with unprecedented precision. The LATR is the largest cryogenic millimeter-wave camera built to date, with a diameter of 2.4 m and a length of 2.6 m. The coldest stage of the camera is cooled to 100 mK, the operating temperature of the bolometric detectors with bands centered around 27, 39, 93, 145, 225, and 280 GHz. Ultimately, the LATR will accommodate 13 40 cm diameter optics tubes, each with three detector wafers and a total of 62,000 detectors. The LATR design must simultaneously maintain the optical alignment of the system, control stray light, provide cryogenic isolation, limit thermal gradients, and minimize the time to cool the system from room temperature to 100 mK. The interplay between these competing factors poses unique challenges. We discuss the trade studies involved with the design, the final optimization, the construction, and ultimate performance of the system.
Runway Excursions: Bearing Strength Control of Unpaved Areas
Authors: Čičmanec Luděk , Ulrich Ondřej
Published: September 2021

The paper deals with the Dynamic Cone Penetrometer application which is intended to work as a vital means to support the bearing strength evaluation over the vast unpaved airport areas. Having identified fundamental drawbacks, the authors proposed some refinements in the original methodology. These predominantly respect the needs of airport operation services. Specifically, the model based on fuzzy logic and two tables, exceptionally suitable for day-to-day applications, are proposed and tested upon the extensive data set acquired at four airports over the last four years.

Market Selection and the Information Content of Prices
Authors: Atakan Alp E. , Ekmekci Mehmet
Published: September 2021

We study information aggregation when
n bidders choose, based on their private information, between two concurrent common‐value auctions. There are
k

s
identical objects on sale through a uniform‐price auction in market
s and there are an additional
k

r
objects on auction in market
r, which is identical to market
s except for a positive reserve price. The reserve price in market
r implies that information is not aggregated in this market. Moreover, if the object‐to‐bidder ratio in market
s exceeds a certain cutoff, then information is not aggregated in market
s either. Conversely, if the object‐to‐bidder ratio is less than this cutoff, then information is aggregated in market
s as the market grows arbitrarily large. Our results demonstrate how frictions in one market can disrupt information aggregation in a linked, frictionless market because of the pattern of market selection by imperfectly informed bidders.
Reconciling Models of Diffusion and Innovation: A Theory of the Productivity Distribution and Technology Frontier
Authors: Benhabib Jess , Perla Jesse , Tonetti Christopher
Published: September 2021

We study how endogenous innovation and technology diffusion interact to determine the shape of the productivity distribution and generate aggregate growth. We model firms that choose to innovate, adopt technology, or produce with their existing technology. Costly adoption creates a spread between the best and worst technologies concurrently used to produce similar goods. The balance of adoption and innovation determines the shape of the distribution; innovation stretches the distribution, while adoption compresses it. On the balanced growth path, the aggregate growth rate equals the maximum growth rate of innovators. While innovation drives long‐run growth, changes in the adoption environment can influence growth by affecting innovation incentives, either directly, through licensing of excludable technologies, or indirectly, via the option value of adoption.
Whither Formal Contracts?
Authors: Sánchez de la Sierra Raúl
Published: September 2021

To measure the benefits of formal contract enforcement for society, I create a market with merchants and buyers, in which buyers can choose whether to buy, and whether to pay. A set of multiple “state‐favored” ethnic groups control the state. I experimentally vary whether formal contracts are required and the composition of buyer‐merchant pairs. The design separately identifies the effect of the contracts on the buyers' incentive to pay and on their incentive to buy. I document two ways in which society limits the benefits of contracts. First, contracts reduce buyer cheating, thus increasing merchants' profits, if, and only if, the merchant is state‐favored. Buyers' beliefs suggest that the merchants can enforce the contracts if, and only if, the merchant is state‐favored. Second, holding constant whether the pair is state‐favored, contracts only influence buyer choices when the buyer and the merchant belong to two, different, state‐favored ethnic groups. Buyers' choices and beliefs confirm that, in that case, the contracts are expected to be enforceable, but they have no effect on buyers' choices because reputation already governs the incentives to cheat within groups. The findings temper the view of the state as independent from society, offer a rationale for why contracts are not adopted, and nuance the notion of state weakness.
Random Evolving Lotteries and Intrinsic Preference for Information
Authors: Gul Faruk , Natenzon Paulo , Pesendorfer Wolfgang
Published: September 2021

We introduce random evolving lotteries to study preference for non‐instrumental information. Each period, the agent enjoys a flow payoff from holding a lottery that will resolve at the terminal date. We provide a representation theorem for non‐separable risk consumption preferences and use it to characterize agents' attitude to non‐instrumental information. To address applications, we characterize
peak‐trough utilities that aggregate trajectories of flow utilities linearly but, in addition, put weight on the best (peak) and worst (trough) lotteries along each path. We show that the model is consistent with recent experimental evidence on attitudes to information, including a preference for gradual arrival of good news and the ostrich effect, that is, decision makers' tendency to prefer information after good news to information after bad news.

CONCEPÇÃO POLÍTICO-PEDAGÓGICA DE SAMPAIO DORIA (1883-1964) E A DEMOCRATIZAÇÃO DA ESCOLA PÚBLICA
Authors: Favaro Neide de Almeida Lança Galvão
Published: September 2021

Este artigo analisa o projeto político-pedagógico de Sampaio Doria (1883-1964), identificando seus fundamentos e os objetivos almejados com a implantação da escola pública em São Paulo, nas décadas iniciais do século XX. Com o aporte do materialismo histórico, tendo como pressuposto a articulação intrínseca entre as concepções políticas liberais e as proposições pedagógicas do autor, examinam-se suas obras e contribuições do período. Sampaio Doria propugnou a Educação intelectual, moral, profissional, econômica, física e cívica para todos, baseada no método de intuição analítica, como mecanismo de regulação das questões sociais e de modernização da sociedade. Foi este o sentido da Reforma do Ensino Paulista que propôs em 1920 e de sua atuação como docente e como jurista, que abrangeu, também, a luta pela democracia, pela prosperidade e pela ordem social. Retomar seu pensamento permite desvelar as funções atribuídas à escola pública brasileira em suas origens.

Morphological and molecular phylogenetic analyses ofZepedanulus ishikawai(Arachnida: Opiliones: Laniatores: Epedanidae) in the southern part of the Ryukyu Archipelago

Published: September 2021

Harvestmen (Arachnida: Opiliones) are soil animals with extremely low dispersal abilities that experienced allopatric differentiation. To clarify the morphological and phylogenetic differentiation of the endemic harvestmanZepedanulus ishikawai(Suzuki, 1971) (Laniatores: Epedanidae) in the southern part of the Ryukyu Archipelago, we conducted molecular phylogenetic analyses and divergence time estimates based onCO1and16SrRNA sequences of mtDNA, the28SrRNA sequence of nrDNA, and the external morphology. A phylogenetic tree based on mtDNA sequences indicated that individuals ofZ. ishikawaiwere monophyletic and were divided into clade I and clade II. This was supported by the nrDNA phylogenetic tree. Although clades I and II were distributed sympatrically on all three islands examined (Ishigaki, Iriomote, and Yonaguni), heterogeneity could not be detected by polymerase chain reaction–restriction fragment length polymorphism of nrDNA, indicating that clades I and II do not have a history of hybridisation. Also, several morphological characters differed significantly between individuals of clade I and clade II. The longstanding isolation of the southern Ryukyus from the surrounding islands enabled estimation of the original morphological characters of both clades ofZ. ishikawai.
Суммы Клоостермана с простыми числами и разрешимость одного сравнения с обратными вычетами
Authors: Korolev Maxim Aleksandrovich
Published: September 2021

Исследуется задача о разрешимости сравнения $g(p_1)+…+g(p_k)\equiv m\pmod {q}$ в простых числах $p_1,…,p_k\leq N$, $N\leq q^{1-\gamma }$, $\gamma >0$. Здесь $g(x)\equiv a\overline {x}+bx\pmod {q}$, $\overline {x}$ - обратный к $x$ вычет, т.е. $\overline {x}x\equiv 1\pmod {q}$, $q\geq 3$, $a$, $b$, $m$ и $k\geq 3$ - произвольные целые числа, причем $(ab,q)=1$. Изучение этого сравнения опирается на новые оценки сумм Клоостермана с простыми числами. Основным результатом работы является асимптотическая формула для количества решений в случае, когда модуль $q$ не делится ни на $2$, ни на $3$.
Модулярные тернарные аддитивные задачи с иррегулярными или простыми числами
Authors: Ramare Olivier , Viswanadham Gopajosiula Kasi
Published: September 2021

Исходная задача, решаемая в работе, - представить классы вычетов по модулю $q$ в виде суммы трех слагаемых, два из которых принадлежат достаточно малым множествам $\mathcal A$ и $\mathcal B$, а третье имеет нечетное число простых делителей (так называемые иррегулярные числа С. Рамануджана) и лежит в промежутке вида $[q^{20r},q^{20r}+q^{16r}]$ при некотором заданном $r\ge 1$. Доказано, что такое представление всегда возможно при условии, что $|\mathcal A|\cdot |\mathcal B|\ge q(\log {q})^2$. Доказательство этого факта приводит к изучению тригонометрических полиномов, члены которых отвечают иррегулярным числам из короткого промежутка, и к отысканию достаточно точных оценок для таких полиномов. В частности, получена равномерная по $r$ оценка $\sum _{q^{20r}\le s\le q^{20r}+q^{16r}}e(sa/q)\ll q^{16r}(\log q)/\sqrt {\varphi (q)}$, в которой $s$ пробегает иррегулярные числа. Для этого развита специальная техника, основы которой были заложены Сельбергом и Мотохаши. Говоря кратко, характеристическая функция множества иррегулярных чисел выражается через семейство билинейных сумм подобно тому, как это делается в методе усиления, разработанном Иванцом и использующем псевдохарактеры (локальные модели). Техника, развитая в настоящей работе, также применима к суммам с функцией Мeбиуса, функцией Лиувилля и функцией Мангольдта (в последнем случае она немного усложняется). Тем не менее она позволяет получить явные оценки; например, в работе доказано, что $|\sum _{X<\ell \le 2X}\Lambda (\ell ) e(\ell a/q)|\le 1300 \sqrt {q} X/\varphi (q)$ при $250\le q\le X^{1/24}$ и любых $a$, взаимно простых с $q$. Получен также ряд других результатов.
Несимметричная оценка суммы множеств расстояний
Authors: Cheong Daewoong , Koh Doowon , Pham Thang
Published: September 2021

Для $E\subset \mathbb F_q^d$ пусть $\Delta (E)$ - множество попарных расстояний между точками из $E$. Используя аддитивную энергию множеств на параболоиде, Ко, Фам, Шэнь и Винь (2020) доказали, что если множества $E,F\subset \mathbb F_q^d$ таковы, что $|E|\cdot |F|\gg q^{d+{1}/{3}}$, то $|\Delta (E)+\Delta (F)|>q/2$. Более того, они установили, что при $|E|=|F|$ показатель $d+{1}/{3}$ является точным. В настоящей работе доказана усиленная версия этого результата в том случае, когда $|E|\neq |F|$. Полученная оценка по существу неулучшаема для нечетных $d$. Доказательство основано на применении $L^2$-оценки для оператора ограничения на сферу нулевого радиуса.

Abstract Gastronomy tourism is one of the youngest and fastest growing branches of tourism. Therefore, it can be said that different searches and expectations for gastronomy tourism have manifested themselves in tourism with food and drink. In this sense, tourists' search for different tastes, different flavors and experiences have brought a new perspective and a new dimension to tourism. Being able to experience different tastes in different geographies means a different excitement and a special memory for tourists. These real destinations have pushed tourism professionals to think about local foods once again and to a serious competition process. Therefore, nowadays, each region, each city and each destination is in search of developing strategies and policies to offer and market their unique local foods to the tourism industry. Destinations are aware that difference and originality are the basis of creating competitive advantage. With this awareness, it strives to identify and protect the elements that give life to its local foods and give them privilege. This effort is not only a sustainable competitive advantage, but also a prerequisite for leaving local foods to future generations. This study focuses on the place and importance of local foods in gastronomy tourism. The advantages of local foods to destinations in gastronomy tourism are discussed. In addition, local food characteristics and factors that give competitive advantage to local foods are analyzed in depth. The factors that add originality to local foods and limit their imitability are presented and examined in this study in concrete. Concrete suggestions and solutions are also offered to all stakeholders to identify and develop the elements that provide competitive advantage to local foods.

The Hermeneutical Task of Postcolonial African Philosophy: Construction and Deconstruction
Authors: Yohannes Eshetu Mamuye
Published: September 2021

Meta philosophical issues surround the topic of African philosophy. What should be counted as African philosophy, and what makes African philosophy so notable has long been a matter of reflection by African and African descended thinkers? One stance taken by African thinkers leans toward ascribing philosophical status to the collective worldviews of Africans embedded in their traditions, language, and culture. By criticizing ethnophilosophy as being unanimous and uncritical, professional philosophers epitomize a philosophy to be a universal, individualized, and reflective enterprise. This tendency of appropriating cultural traits as philosophical and thereby tending to emphasize particularity by ethnophilosophers on the one hand and the universalist claim by professional philosophers puts African philosophy in a dilemma and whereby makes it counterproductive to the neocolonial liberation struggle. The article's central argument is that African philosophical hermeneutics is a panacea for the 'double blockage' that the philosophers currently look into contemporary African philosophy. African hermeneutics is the extension of German and French hermeneutical tradition with the works of Heidegger, Gadamer, and Ricœur. Hermeneutics is a mediation between culture and philosophy and also universality and particularity.

Refugee, asylum seekers, and migrant (displaced) children are at protracted vulnerability levels, and COVID-19 has exacerbated the situation. Zimbabwe accepts refugees but enforces an encampment policy, and displaced populations are encamped at Tongogara Refugee Camp (TRC).  The research gap is that there is very little literature on refugees in Zimbabwe. The research objectives for the study were to explore the challenges that refugees, asylum seekers, and displaced children at TRC face, ascertain how COVID-19 has affected children at TRC, and propose solutions to these challenges. This research relied upon a mixed method of quantitative and qualitative approach considering the immediacy of the COVID-19 pandemic. Secondary data is referred from published articles and organizational reports. The population size of 2,304 children aged 12 to 17 was obtained through the United Nations refugee agency (UNHCR)’s January 2021 population statistics for TRC. A 10% sample of 230 respondents was selected. Non-probability sampling techniques were used in administering a questionnaire through individual and focus group interviews, which were fed into KoBo Toolbox. Data cleaning and analysis were conducted, with SPSS and NViVo for quantitative and qualitative data analysis, respectively.  Ethical considerations of consent, confidentiality, do no harm, and statements to withdraw from the study were employed. The process involved strict observance of World Health Organization (WHO) guidelines on COVID-19. The research was conducted between April 2020 and February 2021. Results showed that displaced children suffered a spectrum of challenges before COVID-19. During the COVID-19 period, respondents had limited access to child protection services, experienced increased conflicts at home, and limited access to formal learning and entertainment: their already dire situation was exacerbated by COVID-19. The study recommends the upgrade of the local secondary school to advanced level status, adoption of educational innovations in lieu of the COVID-19 pandemic, including radio, television, and virtual learning platforms; improved child protection mechanisms; accommodation; dietary diversity; access to water and sanitation hygiene; provision of electricity; adequate street lighting; activities for entertainment; and increasing awareness against child abuse and gender-based violence (GBV).
Anatomy of Nigerian Federalism: A Reflection of the Nagging Challenges and Prospects from A Cultural Relativist Perspective
Authors: Chioke, Stephen Chinedu
Published: September 2021

There is a dearth of reliable literature that appropriately coined and conveyed the conceptual framework of federalism, scarcity of reliable information that analytically x-rayed the structural arrangement of Nigerian federalism, and challenges militating against the expected gains of federalism and the prospects thereof. The paper relied on qualitative methods like document analyses, personal experiences, key informant interviews, and discussions in generating relevant data that were thematically presented and resultantly analyzed using content analysis. The results show that there are works of literature that wrongly conceptualized federalism. Police brutality, political godfatherism, corruption, secession, revenue allocation problem, sectionalism, and conflicts were among the predominant challenges facing Nigerian federalism. Furthermore, the results show that sustainable development and efficient service delivery are part of the prospects. The paper concluded that many Nigerians do not have an adequate understanding of the nitty-gritty of federalism. As a corollary to this, destructive tendencies have troubled Nigerian federalism, making the center epileptic. The study for policy and practice implies that Nigeria, the largest populated country of Africa, has continued its federalist operations on the side of very low cohesion and unification of existing ethnic groups.
China’s Engagement and Africa Beyond Aid
Authors: Evans Tetteh
Published: September 2021

In the current interdependent globalized world, inter-polity engagements are anticipated to unleash and empower economic development. To a larger extent, this, however, could be said not to be the case as evidenced in the African context where relations with the developed world have triggered dependence on foreign aid as a conduit to pursue and gratify vital development needs. Contemporaneously, China’s intensive forays and engagement in Africa since the turn of the twenty-first century has been one characterized by irresistible development assistance to the latter. This situation has ensuingly excited agitations, cardinal among which borders on the claim about the potential deadweight and stymying effect of foreign aid on Africa’s growth and development – thereby adding more odium to the discourse on the call for an ‘Africa beyond aid’ – currently a bourgeoning research sphere. To this end, the objective of this article is to explore how the Chinese aid engagement could relate to the Ghanaian leadership’s clarion call for Africa’s development beyond aid. Consequently, the study employed qualitative data and analysis to interrogate the Chinese aid policies towards Africa, as well as projects implemented across the continent. The findings show that gauging from the policy perspective, much as Chinese aid tends to be well suited to the ‘Africa beyond aid agenda’, it nonetheless exhibits some disquieting implementation features that could impede in the long term, Africa’s development beyond aid. This unappealing situation makes it imperatively urgent for Africa to understand, and strategically align with China’s aid - with recourse to the vision of Africa beyond aid.

Introduction. Food allergy (FA) being a clinically heterogeneous condition, the only treatment for which is a strong elimination diet. The need to exclude one or more foods from the diet, constant monitoring of the diet, anxiety and excitement about the exacerbation of allergic symptoms lead to a significant decrease in the quality of life. Materials and methods. The study included thirty eight 2-7 year children patients with various clinical manifestations of FA (atopic dermatitis, allergic and alimentary colitis, food-borne dermatitis). The comparison group consisted of twenty seven healthy children matched by age. The quality of life in all children was assessed using the Pediatric Quality of Life - PedsQLTM4.0 questionnaire. Results. All FA children patients showed a significant decrease in the quality of life in terms of such indicators as emotional functioning (60.2 in the main group and 83.5 in the comparison group), social functioning (77.9 in the main group and 88.1 in the comparison group), role functioning or kindergarten functioning (FDS) (77.5 in the main group and 84.9 in the comparison group) and psycho-social health (69.3 in the main group and 85.5 in the comparison group). The overall score in assessing the quality of life is significantly lower in the group of FA children (71 in the main group and 87 in the comparison group). Conclusion. To improve the quality of life of children with FA, there is needed a comprehensive individual approach including both psychological support for the child and his family members, and the solution of issues with the provision of «safe» food in children’s educational institutions.

Authors:   Universidad de Monterrey, México, Salazar Garza Ricardo
Published: September 2021

This paper is about developing a nonlinear model to predict the behavior of future exchange rate based on the opinion of the economic agents participating in the dollar/peso market. Such views are treated with Fuzzy Logic and a variant of it, known as the Theory of Forgotten Effects. The aim is to find a mechanism for making coverage decisions that allow us an optimal exchange rate risk management at a lower cost than that which involves operations with traditional hedging instruments. For the period of investigation and applying this model, the results support that the collective opinions of economic experts involved in the decision making risk management of exchange rate provide better results than those using traditional methods in the future markets.
