Authors: Bof Alvana Maria , Viana Basso Flavia , Dos Santos Robson
Published: January 2023

Este estudo tem o objetivo de investigar os possíveis impactos da pandemia de covid-19 na alfabetização das crianças nas escolas brasileiras. Para tal, analisa as estratégias que foram adotadas pelas escolas de anos iniciais do ensino fundamental (EF) no País para a continuidade das atividades de ensino-aprendizagem de seus alunos, durante a suspensão das aulas presenciais causada pela pandemia, e busca verificar os possíveis reflexos dessas novas condições de ensino nos resultados da alfabetização das crianças, comparando dados dos períodos pré e pós-pandemia. Os resultados indicam severas desigualdades na oferta de estratégias de ensino e aprendizagem durante a suspensão das aulas presenciais entre escolas, redes de ensino, regiões e unidades federativas. No que diz respeito aos resultados da alfabetização das crianças nos períodos pré e pós-pandemia, constata-se um aumento considerável, a partir de 2021, no percentual de crianças que não sabem ler e escrever no País, segundo dados da Pesquisa Nacional por Amostra de Domicílios Contínua (Pnad-c). Seguindo essa tendência, os resultados comparativos do Sistema de Avaliação da Educação Básica (Saeb) – 2º ano do EF de 2019 e 2021 evidenciam que aumentou o percentual de alunos cuja proficiência em Língua Portuguesa está localizada nos níveis mais baixos da escala do Saeb, em que os estudantes não demonstram possuir habilidades básicas, como escrever palavras com correspondências regulares entre letras e fonemas a partir de ditados. Desigualdades significativas são verificadas ao se considerarem as regiões geográficas, os entes federativos, o local de residência (rural ou urbano) e a raça/cor das crianças. De modo geral, os resultados sugerem que houve um aumento nas desigualdades após a pandemia.

Este trabalho tem o objetivo de estimar impactos da pandemia no acesso à graduação. Com base em microdados do Censo da Educação Superior e da Pesquisa Nacional por Amostra de Domicílios Contínua, discutimos tendências recentes de recrudescimento das desigualdades de acesso e de alterações no perfil da demanda e da oferta de graduação, com ênfase na expansão das modalidades remotas de ensino. Ademais, mobilizamos dados do Exame Nacional do Ensino Médio 2019-2021 para estimar impactos da pandemia sobre a participação e o desempenho na prova, por meio de modelagens lineares com efeitos interativos e efeitos fixos municipais. Nossos resultados indicam que a edição de 2020 do certame, que ocorreu em plena segunda onda de contágios e apresentou taxas recordes de abstenção, intensificou a associação entre nível socioeconômico e desempenho na prova. Jovens de camadas populares tiveram suas notas ainda mais sacrificadas no contexto pandêmico, sobretudo se desprovidos de itens no domicílio como computador, telefone celular ou internet, o que pode contribuir para uma reelitização da educação superior brasileira nos tempos recentes e futuros
Wrażliwość polskiej gospodarki na zmiany wywołane pandemią COVID-19
Authors: Nazarczuk Jarosław M. , Cicha-Nazarczuk Marlena , Szczepańska Karolina
Published: January 2023

Na kartach historii epidemie pojawiały się z różną częstotliwością oraz zróżnicowanym nasileniem. Jednakże, choroba zakaźna, wywołana wirusem SARS-CoV-2, dała początek pandemii, której przebieg doprowadził do największej światowej recesji od czasów wielkiego kryzysu. Pandemia COVID-19 od początku stanowiła poważne zagrożenie dla systemu gospodarczego, społecznego oraz politycznego, przede wszystkim z uwagi na jej globalny charakter. Zjawisko to wywołało szereg implikacji i poważnie zakłóciło prawidłowe funkcjonowanie poszczególnych gospodarek i gospodarki światowej jako całości. Celem monografii jest identyfikacja skutków pandemii COVID-19 dla sytuacji społeczno-gospodarczej i funkcjonowania rynku pracy w Polsce. Chcąc określić skalę potencjalnych konsekwencji społeczno-gospodarczych dokonano relatywnej oceny sytuacji Polski na tle krajów UE oraz analizy ważniejszych wskaźników makroekonomicznych w ujęciu czasowym. Podjęto również próbę wskazania branż najbardziej dotkniętych skutkami pandemii, a także jej wpływu na funkcjonowanie i przemiany, jakie dokonały się na rynku pracy. Przeprowadzona analiza udowodniła, że pandemia COVID-19 była czynnikiem, który w znaczący sposób zakłócił prawidłowe funkcjonowanie gospodarki. Skala zmian w kontekście koniunktury gospodarczej była ogromna, natomiast zakres oddziaływania pandemii w zależności od branż gospodarki zróżnicowany. Większość negatywnych skutków pandemii COVID-19 była jednak krótkotrwała i w miarę poprawy sytuacji epidemiologicznej nie powinna stanowić poważnej bariery w dalszym rozwoju gospodarczym kraju. Natomiast, najbardziej dotkliwym efektem pandemii w długiej perspektywie, może być nasilająca się inflacja, w tym utrwalenie inflacji bazowej i oczekiwań inflacyjnych na wysokim poziomie. Wyzwanie stanowi również rosnące zadłużenie sektora instytucji rządowych oraz samorządowych, które bezpośrednio i pośrednio będzie ograniczało długookresowe możliwości do tworzenia wzrostu i rozwoju gospodarczego. W konsekwencji wielotorowego zaburzenia działalności gospodarczej, odbudowa oraz długofalowe ożywienie gospodarki będzie wymagać szerokiego spektrum działań, w tym takich, które pomogą zwiększyć odporność gospodarki na przyszłe szoki o charakterze egzogenicznym. Wzrost zadłużenia krajów i dynamicznie rosnąca inflacja mogą stanowić istotne ograniczenie możliwości tworzenia długookresowego wzrostu, a także finansowania niezbędnych przemian. Interwencja państwa, a także wsparcie UE mogą okazać się zatem kluczowe w procesie niwelowania długofalowych skutków pandemii COVID-19 oraz przygotowania gospodarek do ewentualnych przyszłych kryzysów.
Linking Adverbials in Indonesian EFL Students’ Essays: A Corpus-Driven Study
Authors: Oktavianti Ikmi Nur , Sarage Japen
Published: January 2023

Writing is the activity of arranging and organizing ideas that need some logical connectors to make the ideas cohesively structured. There are several plausible means for cohesiveness, including linking adverbials (LAs). This study examines the LA categories found in EFL students’ academic essays and explores how EL students use them. The data were collected from students’ essays compiled as a learner corpus, Learner Corpus of Academic Writing, comprising 52,404 words. The present study employed LancsBox as the corpus tool and The Louvain Corpus of Native English Essays as the control corpus to assist the analysis. The study results show that all primary categories of LAs are found in the corpus. However, the subcategory transition to another topic is absent from the corpus. In the frequency of use, causal resultative LAs outnumber all other categories, followed by additive and adversative LAs. As for the least frequent LAs, the study identified sequential types. In comparison to the native writer corpus, it is found that there are shared similarities, including the categories and the subcategories of LAs found in both corpora. Regarding the frequency of use, the most frequent types are relatively similar with different positions, namely causal resultative and additive LAs, while the least frequent type is sequential. These results suggest more considerations in designing writing materials, especially in regard to transition markers belonging to the sequential category.
High Voltage Gain Bidirectional DC-DC Converters for Supercapacitor Assisted Electric Vehicles: A Review
Authors:   Netaji Subhas University of Technology, Singh Ankit
Published: January 2023

Integration of supercapacitor alongwith battery in electric vehicles (EVs) improves the life cycle of the battery. Additionally, supercapacitor supplies or absorbs a large amount of instantaneous power during sudden demand such as acceleration or regenerative braking operation, hence also improve the dynamics of the internal power system. However, a major challenge with supercapacitor is that its terminal voltage is low and varies in a wide range during charging and discharging operation. Thus, a high voltage conversion ratio based bidirectional DC-DC converters are required to connect the lower supercapacitor voltage to higher DC-link voltage. The steep voltage conversion ratio with continuous gain based bidirectional DC-DC converters are an integral part of such applications. Various high gain converters exist in the literature such as isolated, non-isolated, cascaded, switched, flying capacitor, and coupled inductor based DC-DC converters, however all these converters have some limitations in context to high gain/high power applications. Therefore, to understand the development of next-generation high voltage gain bidirectional DC-DC converter, this paper focus to comprehensively review and classify various bidirectional step-up DC-DC converters based on their characteristics and voltage-boosting techniques. Further, practical suitability of the reviewed converters and future research directions in switched capacitor converters in context to EVs are also discussed in detail.
A case study for a transformational festival creation in Lourinhã, Portugal
Authors: de Carvalho João Malho Ferreira Ribeiro , Gustavo Nuno , Afonso Victor
Published: January 2023

This research aims to evaluate, select, and validate strategic alternatives for implementing a transformational festival proposal in the municipality of Lourinhã, Portugal. The methodological model investigates the historical context, the classical festival themes, and the transformational festival’s characterisation through literature review and an exploratory interview with a major British stakeholder; the market potential through randomised inquiries representative of the Portuguese population; the contextual strategic assessment through a focus group with local stakeholders; and verifying the possibility of validating the concept of a festival design based upon these premises, through an interview with a major national stakeholder and three short interviews. As a result, we characterised transformational festivals, confirmed consumer profile key indicators, and validated a concept design with a hybrid strategic approach, essential to developing a disruptive, attractive, and marketable concept. The originality of the research is related to the return to the origins that these festivals highlight, as opposed to digital trends. The discrepancy between the paradigmatic importance of transformational festivals and their acceptance was highlighted. The research was limited by the lack of stakeholders’ acceptance of participation in the qualitative research.
Causal Dynamics Between Tourism Receipts, Economic Growth, and Real Exchange Rate in Algeria’s Economy Between 1990 and 2019
Authors: Louail Bilal
Published: January 2023

This study aimed to clarify the relationship between economic growth and tourism revenue in the Algerian economy. It focused on the relationship between economic growth, real exchange rate, and tourism receipts. This investigation is intended to fill a gap in the empirical literature on the tourism sector in developing countries. It used the autoregressive distributed lag model adopted from 1990 through 2019. The relationship between economic growth, tourism receipts, and real exchange rate in Algeria is a unidirectional causality relationship; and the tourism receipts and the real exchange rate affect the economy in the short and long term. In terms of long-term equilibrium, there was a positive but nonsignificant impact of tourism receipts on economic growth. At the same time, there was no significant effect of the real exchange rate on economic growth. In the short term, there was a positive and significant impact of tourism receipts lag on economic growth. A positive and significant impact of the second difference lag of the real exchange rate was found. Algerian decision-makers can benefit from these findings when developing the tourism sector. This is the first examination of the effect of these variables in Algeria during the period between 1990 and 2019.
Where is the missing value? Evidence from the game industry IPOs underpricing in Poland
Authors: Śliwiński Paweł , Ablewski Szymon , Gemra Kamil , Łukowski Michał
Published: January 2023

The underpricing phenomenon on financial markets has long been the research subject in many financial areas – from neoclassical to behavioral finance. Once confirmed as a persistent pattern, it has begun an ongoing discussion as to its possible causes. Our study examined the phenomenon of IPO underpricing for companies from the game sector in Poland from 2016 to 2020. Many IPOs in Poland have attracted both international companies and investors, making the Warsaw Stock Exchange a kind of financial hub for game companies. Analyzing the whole IPO market in Poland, we however found substantial IPO underpricing, which is statistically higher in the game sector than in the no-game group of debuting companies. Our research argues that the issuer's industry may influence the size of the IPO's first-day return. We also noticed that the way the IPO was carried out influenced the underpricing. Greater underpricing characterized private offers compared to public offers.

Dysphagia, looking further than the usual suspects, a case report
Authors: Greuter Gert-Jan
Published: January 2023

Background:

Vascular ring is a rare diagnosis in adults as the majority is diagnosed in symptomatic infants or young children. Only a few cases are documented in the literature of dysphagia in adults caused by a vascular ring. It is not uncommon for an adult diagnosed with vascular rings to have asthma in his medical history.

Case Presentation:

A 61-year-old woman presented with dysphagia with a medical history of slight asthma and left hemithyroidectomy. After extensive workup, it was determined to be the result of a right-sided aortic arch with a left-sided arteriosum ligament, a left aberrant subclavian artery with Kommerell’s diverticulum, and a ventral left common carotid artery.

Conclusion:

A right-sided aorta with a left-sided arteriosum ligament is a vascular ring and should be recognized as such. Although rare in adults, one should be triggered to think of a vascular ring in patients with dysphagia, especially with mild asthma and reflux complaints.

Nahdlatul Ulama Theological Basis in Accepting the Concept of Guided Democracy 1959-1965
Authors: Nurjaman Andri , Arzam Arzam , Yusuf Muhamad , Witro Doli , Musadad Anwar
Published: January 2023

Nahdlatul Ulama is the only major political party representing Muslims in national politics during the implementation of guided democracy. NU's accommodative and flexible political practices have made Nahdlatul Ulama able to live and continue to survive in difficult times. This is inseparable from NU's religious political strategy, which is its guideline. The theological basis based on the theory of fiqh and ushul fiqh can be seen in NU's acceptance of the guided democracy concept. This paper aims to reveal NU's theological foundation in accepting the concept of guided democracy. Data was collected through the study of texts and manuscripts and literature studies. The data analysis technique uses hermeneutic theory to capture symbols in the form of texts originating from Islamic law, namely fiqh, and ushul fiqh, as the basis and foundation of NU accepting guided democracy. The results showed that there were several theories of fiqh and ushul fiqh used by NU, including the concepts of maslahah and mudarat, dar’ul mafasid muqoddamun ala jalbil mashalih, amar ma’ruf nahyil mungkar, ma la yudraku kulluh la yutraku kulluh, al-muhafadthu ala qodim al-shahih wa al-akhdzu bi al-jadid al-ashlah, and the concept of syuro presented by KH Idham Chalid.

MTHFR Gene Polymorphisms in Iraqi Kurdish Rheumatoid Arthritis Patients: Relation to Methotrexate Response and Toxicity
Authors: Younis Sherzad Saeed , Issa Najlaa Kadhm , Sulaiman Dhia Mustafa
Published: January 2023

Methotrexate (MTX) is still one of the gold standard treatments for rheumatoid arthritis (RA). It shows diverse outcomes in blood level and clinical response, this was demonstrated by its relation to the genetic polymorphism in the pharmacogenetic study. This study aimed to investigate the role of methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms in relation to MTX efficacy and toxicity in Iraqi Kurdish RA patients. Sixty-four RA patients were involved in this study with an average age of 47.78 ±14.08 and female to male ratio of (8.1). Diagnosis and disease activity were confirmed. Blood analyses, including those of laboratory markers of disease activity, were done. The 28 joint disease activity score (DAS28-CRP) was calculated.  MTHFR gene polymorphisms were analyzed by real-time polymerase chain reaction. The most frequent genotypes which were identified in RA patients were the CT genotype of the C677T single nucleotide polymorphism (SNP) (51.6%) and the AC genotype of the A1298C SNP (48.4%). Patients with non-response to treatment had high frequencies of genotypes CT and TT (58.0% and 12.0%) of the C677T SNP respectively, as compared to those in the responder group; 28.6% and 0.0%); T-allele was associated with drug non-responding OR=4.17, P value=.0.009, meanwhile; genotypes AC and CC of the A1298C SNP were seen in (54.0% and 16.0%) in non-responder group. Patients with active RA had increased frequencies of CT and TT genotypes of the C677T SNP (60.0% and16.0%) respectively as compared to those who were in remission (26.6% and 0.0%); T-allele was associated with high disease activity; OR = 5.11. No association was found between C677T SNP and A1298C SNP, and MTX level status (P> 0.05). However, the variant alleles (T and C) were associated with the MTX toxic level (OR: 2.05, 95% CI [0.97 – 4.32]) and (OR: 1.99, 95% CI [0.96 – 4.18]) respectively. This study suggests that genetic polymorphisms of MTHFR SNP (C677T and A1298C) are associated with MTX efficacy but not toxicity in RA patients. This may assist the physicians in personalizing RA treatment in Iraqi patients.
La revista Los Pensadores y el humor para la crítica de la literatura, el arte y la sociedad
Authors: Da Ré Esteban
Published: January 2023

Regarding the thoroughly discussed polemics between the Boedo and the Florida groups that took place in cultural magazines in the mid 20s, literary critique supports the idea that its display involved a certain distribution of serious and humoristic tones within argentine literary language, which would correspond, in turn, to the classical division between form and content. Whereas the “social art” by Boedo would have focused in seriously toned denunciation, grounded in the seriousness of the problems it addressed, the “art for art’s sake” defended by Florida, would have found in humour a way for literature to reflect about itself and to produce its criticism and self-criticism. However, a re-reading of Los Pensadores, the journal around which the Boedo group organized itself, suggests that a humoristic tone was one of its fundamental strategies for the criticism of the literature and the society of its time, in synch with its literary, cultural and political project.
Subjetividades, escrituras y materialidades chichipatas en Era más grande el muerto de Luis Miguel Rivas
Authors: Ramírez López Wilmar
Published: January 2023

This paper analyzes how the novel Era más grande el muerto reconsider the problem of the representation of sicarial violence through the installation of a new articulation of subjective signification. In this text, from an economic-materialistic angle, Rivas problematizes this modulation of violence from the circulation ways of the commodities and the ways that produce, according to subject ideals, a chichipatas’s subjectivities, which had not been considered in the hegemonic narratives about the topic. In the story this subjectivity articulation spreads to build chichipatas materialities and scriptures that install a new sensible regime more vulnerable, more doubtful, and doubly marginal which configures a rupture in the violence dynamics.

The Impact of Multimodal Discourse Analysis on the Improvement of Iraqi EFL Learners' Reading Comprehension Skill
Authors: Sherwani Kawa Abdlkareem , Harchegani Mohammad Kiani
Published: January 2023

The present study was conducted to investigate the impact of multimodal discourse on Iraqi EFL learners' reading comprehension skill. To achieve the goal, a group including 40  Iraqi EFL learners participated in the free Reading Comprehension course based on their  scores in a Placement Test. Selected participants were randomly assigned to control (N=20)  and experimental (N=20) groups. Prior to the start of the course, both groups were given the pretest (reading comprehension test). The two groups received the same language instruction, but the experimental group was exposed to multimodal treatment (multimodal use of discourse, e.g. video and picture based on Halliday’s social semiotics approach) while the control one did not receive any multimodal treatment. Having accomplished the experiment, participants of the two groups completed two reading comprehension tasks as the posttest.  Results of t-test indicate significant outperformance of the experimental group over the control one.
Colloidal black gold with broadband absorption for plasmon-assisted crosslinking of thiolated diazonium compound

Published: January 2023

Broadband light absorbers are very attractive for many applications, including solar energy conversion, photothermal therapy, and plasmonic nanocatalysis. Black gold nanoparticles are an excellent example of broadband light absorbers in the visible and near-infrared (NIR)ranges; however, their synthesis typically requires multi-step deposition and/or high temperatures. Herein, we report the synthesis of black gold via a facile, one-step green method using commonly known precursors (chloroauric acid and sodium citrate) performed at room temperature. The formation of the black gold particles is driven by self-assembly of in-situ formed small nanoparticles (~ 5 nm) followed by a fusion step forming extensive networks of nanowires. These assemblies form intense hotspots for enhancing the electric field as well as the local temperature. Thus, the nanowires exhibit a strong photothermal effect and SERS performance. The high SERS signal enhancement is used to monitor the kinetics of plasmon-assisted de-nitrogenation and cross-linking of designed thiolated benzenediazonium molecules. Analysis of the reaction performed with external heating in dark and under light irradiation confirmed the charge transfer effect (i.e., hot electrons) to be the dominant mechanism. Our work offers new possibility to design efficient light absorbing materials to achieve good solar-to-chemical/thermal energy conversion.
Molecular design rules for imparting multiple damping modes in dynamic covalent polymer networks

Published: January 2023

Imparting multiple, distinct dynamic processes at precise timescales in polymers is a grand challenge in soft materials design with implications for applications including electrolytes, adhesives, tissue engineering, and additive manufacturing. Many competing factors including the polymer architecture, molecular weight, backbone chemistry, and presence of solvent affect the local and global dynamics, and in many cases are interrelated. One approach to imparting distinct dynamic processes is through the incorporation of dynamic bonds with widely varying kinetics of bond exchange. Here, statistically crosslinked polymer networks are synthesized with mixed fast and slow dynamic bonds with four orders of magnitude different exchange kinetics. Oscillatory shear rheology shows that the single component networks (either fast or slow) exhibit a single relaxation peak, while mixing fast and slow crosslinkers in one network produces two peaks in the relaxation spectrum. This is in stark contrast to telechelic networks with the same mixture of dynamic bonds where only one mixed mode is observed, and here we develop the molecular design rules necessary to have each dynamic bond contribute a distinct relaxation mode. By controlling the polymer architecture and difference in the number of dynamic bonds per chain, we have elucidated the role of network architecture on imparting multimodal behavior in dynamic networks. A highly tunable and recyclable material has been developed with control of rubbery plateau modulus (through crosslink density), relaxation peak locations and ratio (through crosslinker selection and molar fractions), and tan δ (through the relationships of the rubbery plateau and relaxation peak locations).
Computational workflows for novel materials: Case study for lanthanide manganese perovskites
Authors: Kraus Peter , Raiteri Paolo , Gale Julian D.
Published: January 2023

Robust computational workflows are important for explorative computational studies, especially for cases where detailed knowledge of the system structure or other properties is not available. In this work, we propose a computational protocol for appropriate method selection in density functional theory, based strictly on open source software. The protocol is applicable to perovskite systems and does not require a starting crystal structure. We validate this protocol using a set of crystal structures of lanthanide manganates, confirming that PBE+U is a reasonable choice for this purpose, along with the OLYP and HCTH120 density functional approximations. We also highlight that +U values derived from linear response theory are robust and their use leads to improved results. We investigate whether the performance of methods for predicting the bond length of related gas phase diatomics correlates with their performance for bulk structures, showing that care is required when interpreting benchmark results. Finally, using defective LaMnO3 as a case study, we investigate whether the three selected methods can computationally reproduce the experimentally determined fraction of MnIV+ at which the orthorhombic to rhombohedral phase transition occurs. The results are mixed, with HCTH120 providing a good quantitative agreement, while PBE+U better capturing the qualitative aspects of this phase transition.

Background. Although persistent headaches are a common post-stroke pain syndrome, the epidemiology and clinical features of persistent headache after first-ever ischemic stroke have not been considered previously. There is no exact data on how often headache attributed to stroke persists for more than 3 months, i.e. meets the criteria for persistent headache after stroke and what are their distinctive clinical features. The tasks of our study were: to analyze the occurrence/incidence of persistent headaches after the first-ever ischemic stroke; to determine clinical characteristics and types of persistent headaches in comparison with headaches at the onset of stroke.
Materials and methods. The study included 550 patients (mean age 63.1 years, 54% men) with first-ever ischemic stroke, of which 529 patients were followed up for at least three months after the stroke. Standardized semi-structured interview forms were used to assess these headaches during professional face-to-face interviews at the onset of stroke and 3 months after the stroke using telephone interview by neurologist.
Results. Among 529 follow up patients 55 (10.4%) had persistent headaches after first-ever ischemic stroke. Among these 55 patients 34 patients had persistent new-type headaches which arose for the first time during the onset of stroke, they included predominated migraine-like headaches (n=20), tension-type-like headaches (n=9) and thunderclap-like headaches (n=5). 21 patients had persistent headaches with altered characteristics: predominated tension-type-like headaches (n=16), and less common migraine-like headaches (n=5). Persistent headaches after stroke had the following characteristics compared to headaches at onset of stroke: severe headache intensity, a gradual decrease of occurrence of accompanying symptoms (photo- and phonophobia; p=0.03), the transition of unilateral headaches in bilateral (p=0.004), the presence of headaches 15 days per month in 30.9% of the patients.
Conclusion. Persistent post-stroke headaches represent a persistent pain syndrome with severe intensity and frequency of attacks, which requires their further study and creation of guidelines for their management.

Digital-based financial innovation has grown rapidly in recent times along with internet and smartphone penetration. The emergence of fintech and the existence of digital-based innovations carried out by incumbents in the financial services sector, in this case banking, are expected to increase financial inclusion. Furthermore, financial inclusion will encourage the growth of the real sector through increasing new entrepreneurs and also increasing the scale of existing micro and small businesses so that it will ultimately drive economic output growth.

However, to achieve this goal, joint efforts are needed to increase the digital financial literacy of the community, especially the younger generation so that digital financial presence can be used for productive activities. This article discusses community service programs within the framework of developing digital financial literacy to encourage the growth of new entrepreneurs and increase the scale of existing micro and small businesses, especially by utilizing technology..

Published: January 2023

In spite of the vital role played by the stock exchange market in the overall national development, it is still performing below expectations in Nigeria owing to several macroeconomic factors. The main objective of this study is to investigate the effects of selected macroeconomic variables on stock market performance in Nigeria. The study employed time-series data obtained from the Central Bank of Nigeria's statistical bulletin and World Development Indicators. Stock market performance was measured using the all-shares index while the identified macroeconomic variables included GDP growth, broad money supply, exchange rate, savings interest rate, and inflation rate. An Autoregressive Distributive Lag (ARDL) estimation technique was used to establish the long run relationship among the variables, and it was revealed that a long run relationship existed among the variables in the estimated model. The result shows that macroeconomic variables such as gross domestic product, broad money supply, exchange rate, and savings interest rate have a positive effect on stock market performance in Nigeria. On the other hand, the results showed that the inflation rate has a negative effect on stock market performance in Nigeria. Predicated on the result, the study recommended that policies to increase gross domestic product, exchange rate, interest rate, and money supply should be implemented because they can lead to an improvement in the performance of the stock market, while the inflation rate should be maintained at a single digit to prevent its negative effect on the performance of the stock market in Nigeria.

Dzielenie się za darmo i dla zysku: przypadek użytkowników mediów społecznościowych w Polsce
Authors: Filipek Kamil
Published: January 2023

Dzielenie się jest praktyką społeczną, która ulega wielowymiarowym przekształceniom stymulowanym zagęszczaniem się aktywności ludzkiej w mediach społecznościowych. Wraz z rozwojem nowych form komunikacji zmieniają się znaczenia, sensy, schematy, wartości, reguły, podmioty oraz zasoby będące przedmiotem dzielenia się. Wpływ na kształt dzielenia się mają relacje społeczne i wynikające z nich korzyści w postaci zasobów materialnych oraz niematerialnych (kapitał społeczny). Celem artykułu jest analiza wybranych czynników (kapitał społeczny, postawy konsumpcyjne oraz ekologiczne), które mogą wpływać na wybór jednej z dwóch najczęściej spotykanych form dzielenia się: (i) za darmo oraz (ii) dla zysku. Wyniki niniejszych badań (CAWI, N 1508) sugerują, że „zasoby zakorzenione” mają pozytywny wpływ na dwie analizowane formy dzielenia się, zaś „zasoby mobilizowalne” negatywnie oddziałują na dzielenie się dla zysku. Dzielenie się dla zysku jest stymulowane przez postawy konsumpcjonistyczne, a postawy ekologiczne mają pozytywny wpływ na dzielenie się za darmo.
