Seizing Capabilities and Performance of Supermarkets in Kenya
Authors: Ng’ang’a Ann Wambui , Kangu Maureen , Ndegwa Joyce 
Published: June 2024

In Kenya the supermarkets provide market access for the manufacturers’ and small and medium enterprises’ products. In the recent past renowned supermarket brands such as Nakumatt, Tuskys, Choppies and Uchumi have collapsed due to underperformance. This paper examines the influence of seizing capabilities on the performance of supermarkets in Kenyan cities. The study was anchored on the dynamic capability theory (DCT). The study was grounded on positivism research philosophy and adopted crossectional descriptive research design. A structured questionnaire was used to collect primary data from 629 licensed supermarkets. A sample size of 304 respondents from a population of 1258 senior managers was used. Stratified random sampling method was used to select the sample size in Nairobi, Mombasa, Kisumu, and Nakuru. Descriptive statistics such as mean and standard deviation and inferential statistics which included correlation and regression are the statistical tools that were used to analyse the data. Statistical package for social scientists (SPSS) software version 28 was utilized to explore the data. The findings demonstrated that seizing capabilities have a statistically significance (β = 0.511, t = 12.501, p < 0.05) influence on the performance of supermarkets in the Kenyan cities. The study demonstrated that it is vital for supermarkets’ management to consciously design business models and allocate resources that can facilitate the optimal exploitation of new business opportunities to add value to the supermarkets. The management should develop a resource mobilization strategy to fund long term projects that are aimed at seizing opportunities that will improve supermarket’s survival and performance.

Desde o advento do ciclo da borracha somada à criação da Zona Franca de Manaus (ZFM), a cidade de Manaus experimenta um crescimento desordenado em fluxo migratório, demografia, economia, territorial e tem absorvido consequências da urbanização acentuada, como a descaracterização da sua paisagem e fatores socioespaciais como a desigualdade social e invasões clandestinas. No cerne ambiental, o desmatamento e ocupação de áreas de proteção ambiental, e sobretudo o aumento de lixeiras viciadas e despejo do esgoto, transformaram os igarapés, de áreas recreativas em rios carreadores de lixo, esgoto e metais. O presente artigo tem por objetivo descrever as condições da situação da coleta de resíduos sólidos urbanos (RSU) da cidade de Manaus, avaliar os custos de limpeza dos Igarapés, e colocar um enfoque sobre o destino final do lixo gerado em Manaus, o aterro de resíduos sólidos municipais (ARSM) e impactos que o chorume gerado tem ocasionado ao solo e a Igarapés da cidade. A metodologia empregada neste trabalho foi baseada no método indutivo com uso da pesquisa descritiva de artigos de periódicos, teses e relatórios da Secretaria Municipal de Limpeza Urbana (SEMULSP) de Manaus. Os resultados obtidos através de estudos do ARSM têm destacado sua saturação devido ao crescimento da cidade, aumento dos custos de coleta de resíduos sólidos urbanos (RSU) ao longo dos anos de 2013 a 2019, e baixo aproveitamento em reciclagem, compostagem, e biogás. A coleta seletiva, sensibilização ambiental e o combate a lixeiras viciadas são deficitárias, exigindo políticas efetivas de educação ambiental e reaproveitamento do lixo em Manaus.

Neste estudo sobre a Educação étnico-raciais e a Interseccionalidade da Opressão, problematizamos as relações étnico-raciais no contexto da educação, marcada por um percurso pouco acessível para as pessoas negras, oriundas das classes populares, no âmbito das relações sociais de poder, objetivando aprofundar a reflexão epistemológica sobre racismo, tendo como centralidade a interseccionalidade, paradigma referencial interpretativo, usado por teóricas negras, para explicar a inter-relação dos fenômenos sociais das opressões de raça, de gênero e de classe entre outros, nos sistemas de dominação, evidenciando a relação do racismo e do sexismo, na educação. A metodologia utilizada foi a revisão bibliográfica relacionada com o tema em estudo, tendo como base a leitura de obras de bell Hooks (2013, 2019) e Lélia Gonzales(1979,1982,1984,1988) e de autores que tratam sobre o racismo e a educação. Como resultado, evidenciamos o ato do pensar e do atuar na práxis educativa a partir dos conhecimentos subjugados do pensamento feminista negro como uma tarefa fundamental para uma pedagogia libertadora, que surge não só da consciência crítica, mas também do trabalho de resistência à exploração de classe e à interseccionalidade das opressões de gênero, de raça e de sexualidade, entre outras, na prática social das relações de poder e de saber, com vistas à transformação do projeto excludente em um processo emancipatório includente e autônomo da sociedade.
Coxas de Roberto Piva: ars erotica & solidão
Authors: Clemente Fabrício Carlos , Leal Cristyane Batista 
Published: June 2024

Este texto realiza uma leitura do livro Coxas: sex fiction & Delírios, de Roberto Piva, publicado primeiramente em 1979 e depois em 2006, em Obras reunidas, organizadas por Alcir Pécora. Partindo dos conceitos de “Ars erotica”, de Michel Foucault (2012), “política dos anormais”, de Beatriz Preciado (2011) e de performatividade, de Judith Butller (2008), percorremos a linguagem transgressora da poética de Piva. Em Coxas, o homoerotismo ou a sexualidade transgressiva assume as feições do fazer poético, o que se equivale à busca pelo conhecimento e erudição como maneira de empreender, como diz o poeta, a “destruição maravilhosa do Caráter”. Nesse sentido, o anárquico sincretismo brasileiro de Piva radicaliza as visões de Oswald de Andrade, redefinindo a antropofagia em sexualidade transgressiva . Essa abordagem traz novas possibilidades de pensar relações entre literatura e vida, em que um esforço existencial luta e se debate para não ser sufocado pela normalidade triunfante.
Literatura e exclusão social: uma análise dos contos Muribeca, de Marcelino Freire, e Tio, mi dá só cem, de João Melo
Authors: Ribeiro Rondinele Aparecido , Brito Luciana 
Published: June 2024

O presente artigo analisa o conto Muribeca, de Marcelino Freire, e o conto Tio, mi dá só cem, escrito por João Melo. É necessário assinalar que nossa postura acolheu as conjunções motivadas pelos trânsitos existentes entre os países de Língua Portuguesa. Desse modo, a leitura dos textos revela a preponderância do espaço urbano, captado pela ficção como consequência do problemático processo de urbanização de países periféricos situados no contexto de capitalismo avançado. Com isso, a literatura confirma sua vocação em se constituir como um espaço privilegiado que possibilita estabelecer profundas reflexões sobre as desigualdades sociais que emergem como traço constitutivo de países com um passado colonial.

Humanitarian activities of the county police in the second half of the XIX– early XX centuries (on the example of the Vladimir province)
Authors: MOROVA Olga Viktorovna 
Published: June 2024

Law enforcement agencies have been and remain an important part of the Russian state system. The field of responsibility of the police authorities of the Russian Empire at the turn of the XIX–XX centuries was extensive and diverse. It included issues of state, community and public administration, management in the field of economics, industry, transport, finance, control over compliance with laws and regulations, protection of personal rights and property, health care, social security, education, the spiritual sphere and monitoring the moral condition of the population. The article is devoted to the activities of the district police of the Vladimir province in the field of struggle for the physical and moral health of the population. This aspect is insufficiently covered in local-level research, so the author used archival materials from the Vladimir province to complement the image and the scale of the activities of local law enforcement agencies by the beginning of the XX century. Pokrovsky County was the most densely populated due to the high concentration of factory industry and workers. The research is based on the principles of historicism, reliability and scientific character, chronological and historical-systemic methods are used. Specific examples show the role of the county police in combating the spread of infectious diseases and drunkenness among the population, carried out in difficult conditions of active migration flows in cities and counties of the Vladimir province and an ever-growing number of residents. The staff of the Pokrovsky district police department, in addition to the functions of law enforcement and public peace, controlled the opening of hospitals, the provision of medical care, strictly monitored the referral of syphilis-infected residents to county hospitals for treatment, and fought against public drinking in villages and towns of the county. Statistics collected from the field by district police officers were sent to the provincial government, to statistical committees and became the basis for state and public decisions in the relevant areas.

Published: June 2024

Background
Patients with lung adenocarcinoma (LUAD) often develop a poor prognosis. Currently, researches on prognostic and immunotherapeutic capacity of aneuploidy-related genes in LUAD are limited.

Methods
Genes related to aneuploidy were screened based on bulk RNA sequencing data from public databases using Spearman method. Next, univariate Cox and Lasso regression analyses were performed to establish an aneuploidy-related riskscore (ARS) model. Results derived from bioinformatics analysis were further validated using cellular experiments. In addition, typical LUAD cells were identified by subtype clustering, followed by SCENIC and intercellular communication analyses. Finally, ESTIMATE, ssGSEA and CIBERSORT algorithms were employed to analyze the potential relationship between ARS and tumor immune environment.

Results
A five-gene ARS signature was developed. These genes were abnormally high-expressed in LUAD cell lines, and in particular the high expression of CKS1B promoted the proliferative, migratory and invasive phenotypes of LUAD cell lines. Low ARS group had longer overall survival time, higher degrees of inflammatory infiltration, and could benefit more from receiving immunotherapy. Patients in low ASR group responded more actively to traditional chemotherapy drugs (Erlotinib and Roscovitine). The scRNA-seq analysis annotated 17 cell subpopulations into seven cell clusters. Core transcription factors (TFs) such as CREB3L1 and CEBPD were enriched in high ARS cell group, while TFs such as BCLAF1 and UQCRB were enriched in low ARS cell group. CellChat analysis revealed that high ARS cell groups communicated with immune cells via SPP1 (ITGA4-ITGB1) and MK (MDK-NCl) signaling pathways.

Conclusion
In this research, integrative analysis based on the ARS model provided a potential direction for improving the diagnosis and treatment of LUAD.

Published: June 2024

Background
White-rot fungi and bacteria communities are unique ecosystems with different types of symbiotic interactions occurring during wood decomposition, such as cooperation, mutualism, nutritional competition, and antagonism. The role of chitin-active lytic polysaccharide monooxygenases (LPMOs) in these symbiotic interactions is the subject of this study.

Method
In this study, bioinformatics tools were used to analyze the sequence and structure of putative LPMOs mined by hidden Markov model (HMM) profiles from the bacterial metagenomic DNA database of collected humus samples around white-rot fungi in Cuc Phuong primary forest, Vietnam. Two genes encoding putative LPMOs were expressed in E. coli and purified for enzyme activity assay.

Result
Thirty-one full-length proteins annotated as putative LPMOs according to HMM profiles were confirmed by amino acid sequence comparison. The comparison results showed that although the amino acid sequences of the proteins were very different, they shared nine conserved amino acids, including two histidine and one phenylalanine that characterize the H1-Hx-Yz motif of the active site of bacterial LPMOs. Structural analysis of these proteins revealed that they are multidomain proteins with different functions. Prediction of the catalytic domain 3-D structure of these putative LPMOs using Alphafold2 showed that their spatial structures were very similar in shape, although their protein sequences were very different. The results of testing the activity of proteins GL0247266 and GL0183513 show that they are chitin-active LPMOs. Prediction of the 3-D structures of these two LPMOs using Alphafold2 showed that GL0247266 had five functional domains, while GL0183513 had four functional domains, two of which that were similar to the GbpA_2 and GbpA_3 domains of protein GbpA of Vibrio cholerae bacteria. The GbpA_2 - GbpA_3 complex was also detected in 11 other proteins. Based on the structural characteristics of functional domains, it is possible to hypothesize the role of chitin-active GbpA-like LPMOs in the relationship between fungal and bacterial communities coexisting on decomposing trees in primary forests.
Ecotoxicological effects of tungsten on celery (Apium graveolens L) and pepper (Capsicum spp.)
Authors: Li Qi , Zheng Xiaojun , Chen Ming 
Published: June 2024

Background
Tungsten (W) is an emerging heavy metal pollutant, yet research remains scarce on the biomonitor and sensitive biomarkers for W contamination.

Methods
In this study, celery and pepper were chosen as study subjects and subjected to exposure cultivation in solutions with five different levels of W. The physiological and biochemical toxicities of W on these two plants were systematically analyzed. The feasibility of utilizing celery and pepper as biomonitor organisms for W contamination was explored and indicative biomarkers were screened.

Results
The results indicated that W could inhibit plants’ root length, shoot height, and fresh weight while concurrently promoting membrane lipid peroxidation. Additionally, W enhanced the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and total antioxidant capacity (TAOC) to counteract oxidative damage. From a physiological perspective, pepper exhibited potential as a biomonitor for W contamination. Biochemical indicators suggested that SOD could serve as a sensitive biomarker for W in celery, while TAOC and POD were more suitable for the roots and leaves of pepper. In conclusion, our study investigated the toxic effects of W on celery and pepper, contributing to the understanding of W’s environmental toxicity. Furthermore, it provided insights for selecting biomonitor organisms and sensitive biomarkers for W contamination.

Climate change is recognized as one of the most pressing challenges of our time, with profound implications for global food security. This review article delves into the multifaceted impacts of climate change on crop yields and farming practices on a global scale. By synthesizing recent research findings, identifying key challenges and opportunities, and exploring adaptation strategies, this review provides a comprehensive analysis of the complex interplay between climate change and agriculture. The effects of climate change on agriculture are diverse and far reaching. Alterations in weather patterns, including shifts in temperature, precipitation, and frequency of extreme events, pose significant challenges to agricultural productivity and food security. These changes disrupt traditional farming practices, exacerbate water stress, soil erosion, and crop loss, and threaten the livelihoods of millions of farmers worldwide. Additionally, changes in pest and disease dynamics have further compounded the challenges faced by agricultural systems under pressure from climate variability. These challenges, there are opportunities for innovation and adaptation in the agricultural systems. This review highlights the potential of climate-smart agricultural practices such as crop diversification, conservation agriculture, and precision farming to enhance resilience and mitigate the impacts of climate change on crop yields. investments in climate-resilient crop varieties, improved water management techniques, and sustainable land management practices offer pathways for building adaptive capacities and ensuring food security in a changing climate. addressing the complex challenges of climate change adaptation in agriculture requires concerted action at multiple levels. This review emphasizes the importance of coordinated efforts among policymakers, researchers, farmers, and other stakeholders in developing and implementing effective adaptation strategies. Such strategies should be context-specific, socially equitable, and environmentally sustainable, considering the diverse needs and priorities of different regions and communities. This review underscores the urgent need for coordinated action to build resilient and sustainable food systems in the face of a changing climate. By synthesizing the latest research findings, identifying key challenges and opportunities, and exploring adaptation strategies, this review aims to inform policymakers, researchers, and practitioners about the imperative of addressing climate change’s impacts on agriculture. Only through collaborative and transformative action can we ensure food security for the present and future generations in a rapidly changing world.

Published: June 2024

The present study was conducted to determine the effect of different levels of manures, fertilizer, and biofertilizers application, either alone or in combination on seed germination, vigor, and yield of Amaranthus. Recommended rates of organic manures viz., farmyard manure (5 t/ha) and vermicompost (2.5 t/ha) biofertilizers i.e., Azotobacter and Phosphate solubilizing bacteria @ 200g per 10 kg of seed were integrated with the recommended dose of fertilizer @ 60: 40: 20 kg/ha NPK. The experiment was designed with twelve treatments with three replications that were laid out in a randomized complete block design. Results revealed that the treatment T12 which consists of half dose of NPK + half dose of vermicompost + Azotobacter and PSB observed early emergence of seeds (3.60 days) along with higher germination percentages (84.53 percent) as well as vigorous seedlings in terms of vigor index-1 (5.75) and vigor index-2 (5.56). The crop was harvested three times at a height of 20 cm and by the application of treatment T12, plants take minimum time for harvest i.e., 21.65, 30.65, and 41.16 days along with the highest yield i.e., 0.50, 1.15, and 0.85 kg per plot at first second and third harvest respectively. Therefore, it is clear that combining inorganic fertilizers with organic manures could increase soil health in addition to enhancing growth and facilitating consistent nutrition for the Amaranthus crop.
