ASPECTS: interobserver agreement between radiologist
Authors: Andropova P. L. , Gavrilov P. V. , Savintseva Zh. I.
Published: May 2022

Introduction. The Alberta stroke programme early CT score (ASPECTS) was developed for a unified approach to the diagnosis of Acute Ischemic Stroke. ASPECTS is currently used as a standard method for assessment of ischemic volumes in the anterior cerebral circulation. However, the scale is not fully standardized, which is a source of intersubject variability.

The purpose of the review is to gain an understanding the advantages and limitations of the ASPECTS scale, as well as the level of inter-expert and intra-expert agreement.

Results. A literary analysis demonstrates most researchers have identified many factors that affect both the interpretation and assessment of the distribution of ischemic changes by ASPECTS. These signs are diverse and include a wide range of parameters: from methodological standardization to personal factors of experts. Also, studies on the effectiveness of the ASPECTS scale showed quite heterogeneous results, which reflect a wide degree of variability in inter-expert agreement.

Conclusion. The ASPECTS is a systematic, reliable and practical method that is widely used in modern clinical practice. However, the possibility of variability of expert assessments is the main limitation of its application. The pronounced variety of results and the heterogeneity of intrasubject variability does not currently allow us to consider this scale as a truly reliable version of a standardized assessment and may affect the further treatment process. To solve this problem, it looks promising to introduce into clinical practice the methods of semi-automatic and automatic processing of CT images using artificial intelligence systems. But for the full acceptance of such systems into clinical practice, their wide clinical approbation on independent sets of different data is necessary.

Introduction. This report of Listeria monocytogenes infection with the involvment of central nervous system is important due to the increased frequency either in adults or children as well as the usually severe course and high mortality in generalized forms, especially with the CNS involvement. The demonstration of this clinical case, especialy the features of structural changes in the CNS with MRI in the disease’s dynamics, reflects the complexity of differential diagnosis and the evaluation of therapy effectiveness.

Purpose of the study. To present a clinical case of CNS lesion in a 7-year-old child, the causative factor of which was listeria infection, with a detailed description of structural changes in the CNS using MRI studies.

Material and methods. There is a clinical observation of a patient (child) with a diagnosis of listeriosis, secondary generalized form, extremely severe clinical course, with lesions of the central nervous system (meningoencephalitis). A series of magnetic resonance imaging studies of the brain in dynamics against the background of treatment are analyzed. Structural changes were assessed using multiparameter MRI of the brain using the following modes: T1-weighted, T2-weighted, Flair, T1-weighted with contrast, diffusionweighted and diffusion tensor imaging (DWI / DTI), susceptibility weighted imaging (SWI), MR perfusion, MR angiography.

Results. The revealed structural changes in the brain during dynamic MRI examination, as well as their correlation with the data of anamnesis and clinical and laboratory data, made it possible to confirm meningoencephalitis, as well as to evaluate and make adjustments to the treatment.

Conclusion. The described clinical case, the features of the course of the disease and MRI changes, suggest that dynamic MRI research is of great importance in identifying and assessing (including dynamics) structural changes in the brain substance in patients with neurological disorders in infectious diseases. The obtained data can be used by the attending physicians to assess and correct the ongoing therapy, to determine the required amount of rehabilitation.

Published: May 2022

Atualmente os debates sobre a qualidade de vida têm sido crescentes. Acredita-se que ao cuidar de uma criança com alterações neuromotoras, o cuidador tenha seu tempo livre reduzido, tornando-se mais propenso a desenvolver problemas de saúde como complicações físicas, distúrbios da saúde mental e bem-estar, em decorrência da sobrecarga dos cuidados. O objetivo geral do estudo foi avaliar a qualidade de vida do cuidador primário da criança com alteração neuromotora, atendida em um Centro Especializado de Reabilitação no Recôncavo Baiano. A pesquisa é caracterizada como transversal, descritiva, com abordagem quantitativa. Dados das crianças foram coletados em prontuários e dos cuidadores através de questionários (socioeconômicos e o SF-36 adaptado) online (Google Docs), encaminhados através do aplicativo de mensagem. Observou-se que há no cuidador maior comprometimento dos aspectos físicos quando referenciado a dor, seja influenciando nos aspectos pessoais, sociais e/ou lazer, que podem estar refletindo na dependência e limitações apresentadas pela criança, às demandas nos cuidados e ao baixo nível econômico. O estudo possibilitou a ampliação do olhar para além do paciente, uma vez que o bem estar do cuidador pode interferir nos cuidados e no processo de reabilitação da criança por ele assistida.

The effect of the nature of the financing activity on interest rates and Murabaha rates in the emerging economy
Authors: Al Jundi Nawaf Abdullah
Published: May 2022

This study aimed to get acquainted with the impact of the nature of financing activity on the interest rates and Murabaha rates prevailing in commercial banks and microfinance institutions (MFIs) in Jordan, as the main object of microfinance activity is to reduce poverty and unemployment (Lal, 2018). The study used the descriptive and analytical approach to evaluate the extent of variation in interest rates among different financing sectors. The study used a t-test for independent samples to test the extent of statistically significant differences between the interest rates and Murabaha rates between the three types of activity; the one-way analysis of variance (ANOVA) test was also used to test the variance in interest rates between the MFIs. The study found statistically significant differences between fixed interest rates, declining interest rates imposed by MFIs, and interest rates in commercial banks, and between Murabaha rates used in MFIs and Murabaha rates in Islamic banks. Fixed interest rates, declining interest rates, and Murabaha rates were higher in MFIs than the commercial banks and Islamic banks which oppose the main object of a microfinance institution that is helping poor families and small institutions gain access to financial services, The study found statistically significant differences between the interest rates of the MFIs themselves. The study recommended tightening control over the microfinance sector or capping its interest rates (Heng, Chea, & Heng, 2021) to match the interest rates and Murabaha rates in it along with the cost of obtaining funds and operational costs in these institutions.
Sweepstakes reproduction facilitates rapid adaptation in highly fecund populations
Authors: Eldon Bjarki , Stephan Wolfgang
Published: May 2022

Adaptation enables natural populations to survive in a changing
environment. Understanding the mechanics of adaptation is therefore
crucial for learning about the evolution and ecology of natural
populations, and for better conservation and management of natural
resources such as fish stocks. In this review we focus on the impact of
random sweepstakes on selection in highly fecund populations. In random
sweepstakes the distribution of individual recruitment success is highly
skewed, resulting in a huge variance in the number of offspring
contributed by the individuals present in any given generation. We also
describe selective sweepstakes which are well approximated by recurrent
selective sweeps of strongly beneficial allelic types arising by
mutation. We demonstrate that both types of sweepstakes reproduction may
facilitate rapid adaptation. Finally, we review an important case study
in which a model of recurrent selective sweeps is shown to essentially
explain population genomic data of the highly fecund Atlantic cod, with
broad implications for studying the evolution and ecology of highly
fecund populations across domains of life.

Authors: Ur Rehman Hafiz Ihsan , Ahmed Zulfiqar
Published: May 2022

This research seeks to investigate the factors that make young adults materialistic and the outcomes of their materialistic approach.  the study focuses on mediating the role of materialism between the contextual factors (celebrity endorsement and peer influence) and compulsive buying (impulsive and obsessive buying) is the focus of the study. It also looks at the moderating role of the use of social media. The data was collected from undergraduate university students residing in the Punjab province of Pakistan. The structural modelling technique was used to analyze the data. The study results show that materialistic young adults are more involved in impulsive and obsessive buying than others. The results also confirm the findings of previous\researches conducted in other cultures. It also confirms that materialism mediates the relationship between sociological factors (celebrity endorsement and peer influence) and compulsive buying behaviour (impulsive and obsessive buying behaviour). Moreover, it proves the moderating role of social media use in determining and affecting these relationships. This research provides guidelines for the researchers, policymakers, and managers.
Corruption Trends and Graft Control Progress in Sierra Leone: Study of Causes and Remedies
Authors: Fayiah Moses
Published: May 2022

Corruption continues to affect the vast majority of Sierra Leoneans and is regarded as the greatest culprit of poverty, inequality and social cohesion. This publication shed light on corruption trends, control measures, causes, development implications and remedies for combating corruption in Sierra Leone. The data for this article was sourced from secondary/desk review. The secondary data sources were mainly from published articles, government reports, Acts, policies, workshops and conference proceedings, newspaper commentary, Transparency International Annual Reports, Truth and Reconciliation Commission Reports, and NGOs among others. Key words like corruption in Sierra Leone, causes of corruption, negative effects of corruption and bribery, and control measures of corruption were used to search for relevant information. Specifically, the study revealed that corruption was more prevalent from 2003 to 2018 but declined from 2018 to 2021. Most corruption cases in Sierra Leone arise from the abuse of public offices for private gains. Furthermore, systemic analysis of literature showed that corruption arises as a result of low salary wages, political ambition and other sociological factors. From 2019 to 2021, Sierra Leone has made remarkable progress and is been rated below Africa’s corruption average. This might be attributed to the various reforms and the pre-conviction corrupt asset recovery strategy adopted and the massive public outreach and awareness-raising drive adopted by the commission. It is recommended that the Anti-Corruption Commission of Sierra Leone be adequately empowered to go after any individual engaged in corrupt practices regardless of social status, ethnicity, political connection and wealth. It further recommended that the Anti-Corruption Commissioner appointment should not be political but by integrity and sound track record of citizens.

Adanya kasus pandemic covid-19 mendesak pemerintah untuk merubah sistem pendidikan yang awalnya tatap muka menjadi tatap maya yang lebih dikenal dengan pembelajaran daring. Terlihat selama proses pembelajaran daring, motivasi belajar siswa menurun, terutama pada pembelajaran matematika. Penurunan motivasi belajar siswa ini juga terjadi di kelas X IPS 1 SMA Negeri 1 Bantul, Yogyakarta. Setelah dilakukan penyebaran angket motivasi belajar kepada siswa, kemudian dilakukan anaisis data,diperoleh skor rata-rata motivasi belajar siswa kelas X IPS 1 SMA Negeri 1 Bantul berada pada kategori sedang. Dari 32 siswa di kelas, terdapat 2 siswa dalam kategori sangat tinggi, 11 siswa dengan tingkat motivasi tinggi, dan 19 siswa dengan tingkat motivasi sedang.

Variation in individual and collective behaviours by chacma baboons using urban space in Cape Town, South Africa
Authors:   , Bracken Anna
Published: May 2022

As human populations continue to grow, so does the demand for space – with urban centres encroaching into wild animal habitats. Social, generalist species, which show high rates of innovation and behavioural flexibility tend to adapt to and use human-altered landscapes. However, we know less about what factors drive differences among individuals in use of human-altered landscapes, or the repercussions of individual differences for social dynamics in animal groups, which I review in my introductory chapter (Chapter 1). In Chapter 2 I introduce my study system and methods. I study chacma baboons (Papio ursinus) in Cape Town, South Africa that frequently have negative interactions with people at the urban edge and are managed by a team of rangers that herd the baboons from urban spaces, using aversive conditioning. Using high-resolution GPS data (recording at 1Hz frequency) combined with behavioural observations, field ranger survey and hormonal data I investigate variation in individual and collective behaviour associated with urban space-use. First, I examine variation in the time individuals spend in urban space, and contrary to expectations, find that females, rather than males, spend most time in urban space, and tend to use urban space with other group members and not with vulnerable offspring (Chapter 3). Second, I examine predictors of variation in urban space-use, and find that socially-peripheral, low-ranking female baboons make the most use of urban space, which is likely as a result of a management focus on adult males (Chapter 4). Further examination of fine-scale movement trajectories revealed both baboon phenotype and personality effect individual-level movement in urban space, where baboons most targeted by management show the greatest flexibility in movement (Chapter 5). Finally, I show that use of urban spaces drastically effects group dynamics, reducing cohesion and coordination of the troop, though high-ranking adults consistently lead the troop both in and out of urban space (Chapter 6). I synthesise these major findings in my final discussion chapter (Chapter 7) and discuss how my results will be important in current and future management of the Cape baboons and provide a basis for future examinations of urban space-use across species and systems.

Este artigo tem como objetivo identificar as oportunidades de aprendizagem profissional viabilizadas a professores durante um processo formativo, tomando-se como foco de análise o planejamento da formação e as ações da formadora para desenvolvê-lo. O presente estudo é de natureza qualitativa e construcionista, dentro da perspectiva teórica do interpretativismo. Realizaram-se as análises a partir dos documentos do processo formativo e uma entrevista de lembrança estimulada com a formadora complementou-as. Os resultados revelaram que os participantes vislumbraram possibilidades de desenvolver o Pensamento Algébrico com estudantes dos anos iniciais, participaram de discussões matemáticas e didáticas sobre a propriedade do elemento oposto, do elemento neutro (adição e multiplicação) e do significado de equivalência do sinal de igualdade e refletiram sobre os conhecimentos dos estudantes do 5.º ano do Ensino Fundamental relacionados ao desenvolvimento do Pensamento Algébrico. E as escolhas da formadora possibilitaram articular as dimensões matemática e didática, aproximar a Matemática Acadêmica da Matemática Escolar, vinculadas ao Pensamento Algébrico, e favoreceram interações discursivas pautadas na argumentação e na justificação e em momentos de trabalho individual e coletivo, com a finalidade de ampliar conhecimentos.
uso de Representações Auxiliares na Aprendizagem Matemática

Published: May 2022

Neste estudo, procurou-se analisar o uso de representações auxiliares no ensino de matemática sob o ponto de vista da teoria semiocognitiva de aprendizagem matemática de Raymond Duval. Essa análise tomou como parâmetro principal a comparação semiocognitiva entre as representações didáticas criadas e a representação principal que caracteriza o objeto matemático em estudo. Observou-se a relevância dessas representações criadas como um meio para melhor conhecer os sistemas semióticos usados, pois podem oportunizar a discriminação de unidades significantes por meio da operação de tratamento. Tal discriminação tem importância fundamental, por possibilitar a coordenação da operação de conversão entre os sistemas semióticos envolvidos.

The objectives of this research were to find out: i) the correlation between the students’ critical reading strategies and their reading comprehension achievement and ii) which aspects of reading comprehension significantly correlate with students’ critical reading strategies. This research was quantitative research. The subjects of this research were 30 students of SMKN 1 Kotabumi, North Lampung. The data were collected through questionnaire and reading comprehension test. The result showed that there was a statistically significant correlation between the students’ critical reading strategies and their reading comprehension achievement. Furthermore, reading aspects in terms of inference, determining main idea, and identifying specific information of the text had a statistically significant correlation with the students’ critical reading strategies. This suggests that critical reading strategies facilitates students to improve their reading achievement.
