O objetivo deste estudo é compreender a partir da literatura científica atual o perfil das vítimas de traumatismo cranioencefálico, e os fatores relacionados a este agravo. Esta pesquisa se configura como uma revisão integrativa da literatura, embasada na estratégia PICo, por meio dos descritores: complicações; fator de risco e traumatismos craniocerebrais. A busca dos artigos ocorreu nas bases de dados LILACS, MEDLINE, BDENF, IBECS e CUMED, via BVS, tendo por filtro o recorte temporal de 2018 a 2023, artigos primários, disponíveis na íntegra, na língua portuguesa, inglesa ou espanhola. Neste sentido, com a aplicação dos descritores nas bases de dados obteve-se um total de 851 artigos, após a aplicação dos critérios de inclusão e exclusão conseguiu-se 101 artigos que seguiram para leitura prévia, destes, 23 seguiram para leitura completa, excluindo-se 13, e a amostra final foi de 10 artigos. Assim, observou-se que entre as principais vítimas de traumatismo cranioencefálico a população masculina representou maior prevalência, em idade reprodutiva de 30 a 50 anos, por vezes associados a quedas da própria altura e acidentes de trânsito. Neste cenário, foi possível constatar que as hemorragias intracranianas emergiram como principais fatores agravantes desta lesão, capazes de repercutir em sequelas temporárias ou permanentes. Outro ponto evidenciado foi acerca das implicações do TCE na saúde mental de suas vítimas, bem como as complicações neurodegenerativas a ele associadas. Evidenciou-se que o TCE prevalece entre os principais agravos identificados nos atendimentos dos serviços de urgência e emergência, capaz de perpetuar cadeias de repercussões na saúde física e mental das vítimas, bem como corrobora com a necessidade de internações prolongadas em algumas manifestações e a necessidade de um aporte hospitalar intensivo para a promoção, recuperação e reabilitação da saúde.

Published: September 2023

The organization of modeling the anti-crisis development of agro-food enterprises in the system of innovation and investment management was significantly updated during the war. The study aimed to study the modeling of anti-crisis development of agro-food enterprises in the design of creation and investment management. It has been proven that the anti-crisis management system in organizing the practical work of personnel creates conditions that determine the exceptional priority of the development of professionalism and qualifications of personnel at all levels of agro-food enterprises in the innovation and investment management system. The task of anti-crisis management is to maximally facilitate programs of professional development of personnel based on the proposed model since these measures relate to the development of social capital without disrupting the economic mechanisms of economic regulation. A single agri-food information system will replace paper document flow with an electronic one and automate work processes at agro-food enterprises. In this way, a single information space will be created. When all agro-food enterprises are combined into a single information system, remote control is possible, the purpose of which is to obtain regulated reporting. Conclusions. Conclusions. Implementing the proposed model of formation of the organizational and economic mechanism of anti-crisis management of agro-food enterprises in the innovation and investment management system will allow them to overcome the crisis and stabilize their condition. A unique role in overcoming the problem in the agro-food sector belongs to the implementation of the compulsory insurance system. The functions of information and analytical support should not be underestimated, which includes an information system for forecasting the unfolding of a crisis in the development of agri-food enterprises, information support for a cluster analysis of the crisis state of agri-food enterprises by region, and a single information agri-food system.
Keywords: modeling, anti-crisis development, enterprises in the agricultural sphere, systems, innovation and investment management.

Etnomatemática e Ensino de Matemática: o que revelam as pesquisas da BDEm
Authors: Rebouças Ana Priscila Sampaio , Almeida de Oliveira Kelly
Published: September 2023

A Etnomatemática é um Programa de Pesquisa e uma Teoria Geral do Conhecimento, proposta por Ubiratan D’Ambrosio, que investiga as relações entre matemática e cultura. Neste artigo, busca-se compreender as implicações pedagógicas da Etnomatemática para/com/no ensino de matemática na Educação Básica, tendo como referência as produções disponibilizadas na Biblioteca Digital EtnoMatemaTicas – BDEm. Para alcançar o objetivo proposto, realizou-se um estudo bibliográfico na BDEm sobre Etnomatemática e ensino de matemática. As principais referências são Freire (2019), Lima (2019), Lima (2018) e Morais (2016). A abordagem metodológica é qualitativa, descritiva e interpretativa. Como resultados, destacamos: a predominância de trabalhos cadastrados na BDEm oriundos do estado do Rio Grande do Norte; a multiplicidade de grupos culturais representativos desse estado; a Etnomatemática como subsídio ao ensino e aprendizagem de matemática a partir do entrelaçamento entre currículo e componentes socioculturais, e de situações-problema. Concluímos que a Etnomatemática tem modificado formas de ver e ensinar matemática.
¿Extraer la raíz de un cuadrado? Matemática y metáfora
Authors: Lizcano Emmánuel
Published: September 2023

A linguagem matemática é habitualmente considerada como modelo de linguagem rigorosa e isenta, tanto de ambiguidades como de pré-juízos sociais ou históricos. Sem dúvida, como veremos, é uma linguagem carregada de metáforas, através das quais os significados passam das línguas maternas à linguagem matemática (a metáfora consiste no traslado de significados). Nesse trânsito, os pré-juízos e crenças de cada cultura e cada época histórica vão dando forma aos conceitos, operações e argumentações dos matemáticos, por mais severos que sejam. Analisamos aqui duas metáforas que modelam o coração de duas operações matemáticas fundamentais: a raiz quadrada e a subtração. Extrair a raiz de um quadrado, ou seja, calcular o lado de um quadrado cuja substância tenha o poder (o potência) de alimentar ou engendrar todo o quadrado, é trasladar-nos do campo da geometria ao da botânica e raciocinar como se tratássemos com plantas em lugar de fazê-lo com figuras geométricas que, como sabemos, são objetos inanimados sem nenhuma potência nem raízes das quais se alimentam. Por outro lado, para pensar a metáfora que habita sob a subtração fazemos uma comparação com sua operação equivalente na China clássica e nos questionamos como se extrai ou subtrai; isso o fazem como quem enfrenta magnitudes opostas. No marco de nossa metáfora, não podemos subtrair de donde não há, e por isso os números negativos foram impensáveis para os melhores matemáticos de nossa história… até que se puseram a pensar como os chineses: não por subtração, mas por oposição. Concluímos mostrando como julgaram essas duas metáforas (subtração e oposição) na resolução da crise que hizo tambalearse à teoria de conjuntos.
Balanças: as rotas de uma herança ancestral
Authors: Zuin Elenice de Souza Lodron
Published: September 2023

Neste artigo, faço uma digressão histórica de um instrumento que, ao longo dos milênios, se tornou fundamental para as transações comerciais: a balança. A necessidade de mensurar a massa dos objetos foi posterior às demandas por precisar as medidas lineares e de volume. Desde os seus primórdios na civilização egípcia, com suas finalidades rituais, as balanças percorreram um longo ciclo, atendendo às cerimônias sagradas e às imposições seculares. Este percurso se liga às práticas socioculturais. Com as balanças, também nasceram as unidades de massa, distintas nos diversos núcleos que as gestaram. Balanças justas e pesos justos são também referidos na Bíblia. Foram criados novos tipos de balança e modos de aferição atendendo às necessidades de cada época, lugar e aos avanços tecnológicos. Este longo percurso culmina com a mais recente redefinição do quilograma, estabelecida na segunda década do século XIX, quando o valor da Constante de Planck passou a ser empregado para se calibrar as balanças de precisão.

Published: September 2023

This paper delves into bridging the gap between theory and implementation in the context of post-pandemic workplace design. It examines challenges and solutions in translating theoretical principles into practical architectural applications. The global impact of COVID-19 has underscored the need to address workplace design to mitigate virus transmission risks and create safer environments. Workplaces, due to their high occupancy, can facilitate virus spread, prompting international health organizations to release pandemic-related standards. These standards have influenced the redesign of internal workspaces, necessitating adaptation to new safety measures. This study explores post-pandemic design principles for workplace layouts and their significance for architectural firms striving to provide safer workplaces while adhering to new guidelines. It offers an overview of workplace safety measures in the Design District, a unique creative hub in Egypt. This district showcases innovative design features aligned with the pandemic-induced changes, encompassing offices, showrooms, exhibits, entertainment spaces, serviced apartments, and various amenities. The study underscores the incorporation of key criteria like accessibility, transportation, safety, population density, surroundings, views, air quality, noise, and technology. Additionally, it emphasizes the expansion of space dimensions, circulation, indoor/outdoor connections, technology integration, and biophilic elements due to infection concerns. The objective is to create a healthy, safe, and adaptable environment. To achieve this, the research employs a mixed-methods approach involving a literature review, questionnaires, interviews with industry experts, case studies, and data analysis. This multifaceted approach aims to comprehensively understand modified design guidelines and their implications post-pandemic. The paper’s outcome will provide enhanced design solutions, offering a detailed comparative analysis between pre- and post-pandemic spaces. Such an analysis is crucial to elevating operational efficiency and development in projects like the Design District. The ultimate goal is to create spaces that are resilient and optimized for evolving challenges.
Subverting Religious Hegemony: A Psycho-Feminist Examination of Nuruddin Farah’s Hiding in Plain Sight
Authors: Karumba Julia Njeri , Rutere Albert Mugambi , Goro Nicholas Kamau
Published: September 2023

This paper examines how patriarchy is advanced through religion which in the context of this study refers to the way people connect with a supreme being and the way especially different genders relate with each other. Patriarchy is entrenched in culture and is one of the cultural aspects through which women, financially and socially weak men and children are subjected to domination by the hegemonic male. The study interrogates how those subjected to patriarchal domination are defying the dominating facets of religion in order to deconstruct the oppressive patriarchal structure. The study makes reference to Nuruddin Farah’s Hiding in Plain Sight (2014). Since the source of the conflict in this primary text takes place in Somalia where the majority of people are Muslims, the paper will specifically focus on the way hegemony is advanced through the Islamic religion. The study makes the assumption that defying the dictates of the Islamic religion doctrines is equivalent to challenging the hegemony that is exercised through Islam. Religion as a cultural aspect is inculcated in the minds of the characters from a tender age and thus, they grow up believing in and practising the doctrines of the religion. The study concludes that the desire to liberate themselves makes those subjected to patriarchal domination to challenge the existing patriarchal constructs domiciled in the religion. The arguments in the study are based on psycho-feminist criticism. Psycho-feminist ideology is employed by characters who wish to un-learn the religious doctrines inculcated in them and challenge patriarchal structures within the religion in order to liberate themselves
The Prevalence of Physical Violence, Drivers of Imprisonment, and Conduct of Prisoners in Mogadishu Central Prison, Somalia
Authors: Ahmed Bashir Ali , Odongo Alfred Owino , Gontier Christopher
Published: September 2023

Violence is described as the intentional use of physical force against a person, oneself, or a group of people that causes trauma, psychological harm, or even death. It could take the shape of physical or psychological harm, deprivation, or emotional or sexual assault. Violence of many different kinds is committed in jails globally. However, they are frequently carried out in secrecy, which makes them challenging to establish. The target population for the study were prisoners and staff in Mogadishu Central Prison. A descriptive cross-sectional research design was applied to collect both quantitative and qualitative data. Systematic sampling was used to select prisoners, while purposive sampling was used to select key informants (staff). The study used questionnaires and key informant interviews as data collection tools. Quantitative analysis was conducted using SPSS version 27, and both Fisher’s exact test and Pearson’s Chi-square were used to test for associations and relationships between variables after descriptive analysis had been done. Qualitative analysis was conducted using thematic analysis. The study found that the overall prevalence of physical violence in the prison was 16.3%, with the majority of violence being conducted by convicts against other inmates, but there were also instances of violence committed against and committed by prison staff. The prevalence among inmates was 15%, and prisoners against warden was 1.3%. The most common types of physical violence were fist fights (11.8%), flogging (1.6%), use of weapons or other instruments (1.6%) such as razor blades, throwing shoes at each other, or use of finger rings and slapping (1.3%). The study highlights a concerning high prevalence of physical violence within Mogadishu Central Prison, primarily perpetrated by inmates against each other and occasionally involving prison staff. To address the issue, the study recommends a multifaceted approach, including heightened conflict recognition and resolution training for prison staff, increased investment in resources to alleviate overcrowding, and the establishment of rehabilitation and mental health programs to target the underlying triggers of violence
Validating virtual reality for time perception research: Virtual reality changes expectations about the duration of physical processes, but not the sense of time
Authors: Bogon Johanna , Högerl Julian , Kocur Martin , Wolff Christian , Henze Niels , Riemer Martin
Published: September 2023

Immersive virtual reality (VR) provides a versatile method for investigating human time perception, because it allows the manipulation and control of relevant variables (e.g., the speed of environmental changes) that cannot be modified in the real world. However, an important premise for interpreting the results of VR studies, namely that the method itself does not affect time perception, has received little attention. Here we tested this assumption by comparing timing performance in a real environment and a VR scenario. Participants performed two timing tasks, requiring the production of intervals defined either by numerical values ("eight seconds") or by a physical process (“the time it takes for a bottle to run out when turned over"). We found that the experience of immersive VR exclusively altered judgments about the duration of physical processes, whereas judgments about the duration of abstract time units were unaffected. These results demonstrate that effects of VR on timing performance are not driven by changes in time perception itself, but rather by altered expectations regarding the duration of physical processes. The present study validates the use of VR in time perception research and strengthens the interpretation of changed timing behaviour induced by manipulations within VR.

Published: September 2023

This article describes an approach for synthesizing silicon phosphide nanoparticles with a defective zinc blende structure under mild conditions through thermal annealing of hydrogenated silicon nanoparticles with red phosphorus. The synthesized Si3P4 nanoparticles were analyzed using FTIR, XRD, electron diffraction, EDX, TEM, Raman spectroscopy, X-ray fluorescence spectrometry, and UV–vis spectrophotometry. For the isolated cubic Si3P4 phase, a cell parameter of a = 5.04 Å was determined, and the bandgap was estimated to be equal to 1.25 eV. Because of the nanoscale dimensions of the obtained Si3P4 nanoparticles, the product may exhibit several exceptional properties as a precursor for diffusion doping of wafers and as anode material for Li-ion batteries. A similar method with a hydrogenation step offers the possibility to obtain other compounds, such as silicon selenides, arsenides, and sulfides.
Traditional Arbitration Institutions and Conflict Resolution Approaches in Nigeria: The Efficiency and Rhetorical Fallacy
Authors: Falusi Fisayo Samuel , Owoeye James Damilola , Olabamiji Aminat Abiodun
Published: September 2023

Before the advent of colonialism and its attendant degradation of African culture, Africans have had a concrete knowledge about what conflicts are, what causes conflicts and how conflicts are resolved.  Prior to western education, the Africans have developed a robust knowledge about the dynamics of conflicts and they have had institutionalized means of resolving their conflicts. In the present dispensation, however, the phrase ‘Traditional Arbitration Institutions’ has been given prejudiced responses by the westerners who dominated the study of peace with their scholarly works and claimed a monopolized knowledge of peace. Premised on this background, this paper focuses attention on exposing the systematic knowledge of Africans about disputes and conflicts resolution, using Nigeria as area of study; the paper discusses the conceptual meaning of Traditional Arbitration Institutions (TAI) and conflict resolution; the study seeks to identify and examine the roles of Traditional Arbitration Institutions in promotion of conflict resolution in Nigeria society. In addition, it examines various Traditional Arbitration Institutions (TAI) conflict resolutions mechanism and approaches put in place in resolving disputes and conflicts in Nigeria. The research methodology employed in the study is mixed methods which involves qualitative and quantitative research technique. This work adopted Traditional Arbitration Theory. The paper observes that there is a need for engaging Traditional Arbitration Institutions in resolving community and industrial based disputes and separatist’s agitation in Nigeria. The paper concludes by recommending various Traditional Arbitration strategies that can be adopted to complement existing efforts of promoting peace and stability in Africa.

The first purpose is to produce a literate and numerate population that can jointly deal with problems both at home and at work. Therefore, the paper recommended that Parents and teachers should find ways of promoting the level of creativity of the pupils, as a high level of creativity has an influence on academic performance. Also, Parents of pupils with low levels of creativity should give their children more support and encouragement to improve their level of academic performance in their learning subjects
Returning to Work After Sickness Absence Due to Low Back Pain: A Poetic Representation
Authors: Chetty Laran
Published: September 2023

The purpose of this project was to capture the voices of clients through a poetic representation of their experiences and perceptions as they shared their stories of returning to work after a period of sickness absence following an episode of LBP. A retrospective evaluation of electronic chart notes of clients at an occupational health clinic in London, United Kingdom presenting with LBP who were returning to work were reviewed over a six-month period from January 2023 to June 2023. Verbatim comments of clients about their experiences and perceptions were extracted from the electronic chart notes and analysed thematically. A total of 68 electronic chart notes were retrieved and reviewed by a senior physical therapist. A poem called “The struggle within” was developed to represent the experiences and perceptions of clients as they shared their stories. Healthcare professionals should engage not only in evidence-based interventions, but also with the narratives and stories of individuals to ensure a more holistic approach. A poetic representation is one way that healthcare professionals can frame these dialogues.

Poultry-related foods are consumed as good and cheap sources of protein globally. This research investigated the levels of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn in poultry feeds, water samples, and broilers obtained from poultry farms randomly sampled within Uyo Metropolis. These poultry-related products were obtained, treated, and analysed spectrophotometrically using standard analytical techniques. Results showed that, the concentrations of all the metals in poultry feeds and broiler meat were within their recommended limits however, mean levels of Cd and Fe in water sample was higher than their permissible limits.  Concentrations in poultry feeds were generally higher than their levels in broiler meat. Multivariate analyses indentified varied factors responsible for the accumulation of these metals in feeds, water samples, and broiler meat examined. The estimated daily intake (EDI) of Cd, Fe, and Zn were higher than their oral reference doses (Rfds) for both the children and adults’ populations. The hazard quotients (HQ) of Cd, Fe, Pb, and Zn for both populations were also higher than one (1). The hazard index of the metals for populations were higher than one but, the children class were more susceptible to non-carcinogenic risks. The incremental lifetime cancer risk (ILCR) for the carcinogens varied between medium to very high cancer risk classes. The total cancer risk (TCR) for the children and adults’ populations were 1.54E-01 and 1.43E-01, respectively higher than the standard limits. The relative risk (RR) analysis identified Cd as metal with the highest potential to cause cancer and non-cancer risks in the consumers of broiler meat from the studied poultry farms. This study has indicated the significance of assessing poultry feeds and related products to establish to the quality.

The study investigated the effects of educational cartoons on the learning outcomes of pre-nursery pupils in Ado-Ekiti, Ekiti State. The study adopted the pretest, post-test control group design. The population of the study consisted of all the pre-nursery pupils in private schools in Ado Metropolis. The sample of the study comprised 36 pupils who were selected through simple random sampling technique. An instrument titled Educational Cartoons and Pupils’ Learning Outcomes (ECPLO) was used to collect the data for the study. The validity of the instrument was ensured by experts in Language Education and test and measurement. A test-retest method was used was used to determine the reliability of the instrument while Pearson Moment Correlation Method was used to analyse the result which yielded a reliability co-efficient of 0.78. The finding of the study revealed that there is significant effect of educational cartoons on the learning outcomes of pupils in the experimental group. Based on the finding and conclusion of the study, it is therefore recommended that teachers should be encouraged to incorporate educational cartoons in teaching their pupils so as to foster good academic performance. Parents should also be encouraged to streamline the kind of cartoons they exposed their children to.
Integrating Public Private Partnership Strategy for Sustainable Students Skills Development in Technical and Vocational Education and Training in Zimbabwe

Traditionally, Public-Private Partnerships(PPPs) are known to contribute to infrastructure development in diverse socio-economic sectors. It is a misconstruction that PPPs are streamlined to a single functioning of developing and improving infrastructure yet this strategy can be adopted to integrate PPP for sustainable skills development in Technical and Vocational Education and Training (TVET) with a view of responding to the labour market demand realities. Using a mixed methods approach the study sought to establish the feasibility of PPPs for sustainable skills development in TVET by soliciting data from institutions of higher learning and industry. A simple random sampling of 5 TVET institutions and 10 lecturers,5 administrators, and 5 captains of industry were purposively sampled to respond and participate in the study respectively. The data were descriptively and thematically analyzed for a balanced view of the findings. The results revealed that TVET institutions did not consider PPPs as a strategy for sustainable skills development for employability. Also established was policy inconsistency at the government level which hampers possibilities of partnerships in skills development. The results further show that industry plays an important role in skills development through internship, traineeship, and on-the-job education and training. The study recommended government through the relevant ministry and agents expedite the PPPs policy framework to include skills development as a standalone component. There is a need for government to incentivise private sector players to have PPPs in sustainable skills development for increased return on investment and subsequently economic growth.

Wireless sensor networks (WSNs) are intelligent communication systems that assist in the industrial revolution of IoT. Sensor nodes present in WSNs often have limited battery lifetime due to their energy limits. Ability to replace or recharge the battery supply for networks in largescale or remote sites has been a major drawback. Clustering, duty cycling, data aggregation and routing has been major energy efficiency techniques employed to address energy problems. Due to the poor performance of the traditional LEACH, this paper employ the GWO CRT-based forwarding and splitting techniques to enhance the performance of LEACH. The simulation is done on MATLAB 2018a and the obtained results prove that the proposed protocol i.e., GWO CRT-based outperforms the existing models such LEACH, improved LEACH etc., with respect to energy consumption, throughput, and the lifespan of the network.

The Nigerian Youth cannot be ruled out in the study of active contribution to the Nigerian political system, national stability, cohesion, and development, due to their orientation, attitude, and reactions to national issues. Political parties are the avenue for electing representatives of the people and to this effect, the Nigerian Youth have been trying to take a meaningful hold of the Nigerian parties by trying to be major political gladiators. Premised on this background, this paper is set to discuss the conceptual meaning of youth, political parties, and peacebuilding. In the same vein, it will establish the connection and relationship between youth partisanship and peacebuilding in Nigeria. Moreover, the study seeks to examine the pivotal roles the Nigerian youth play in enhancing peacebuilding and national stability as members of political parties in Nigeria, whilst also attempting to determine to what extent the youth have been contributing to conflicts and peace-building in Nigeria. The data for this study were collected through primary and secondary sources. The primary data were collected through the Interview with Key Informant Interviews (KIIs), Direct Observation (DO), and participant observation. In addition, youth organizations, amongst others, were interviewed. The secondary sources include books, journal articles, periodicals, magazines, and other publications relevant to the study. The data were analyzed using a qualitative approach. The peace-building theory was adopted as the theoretical framework for the study. The findings of the study revealed that the Nigerian Youth, in these contemporary times, have been actively involved in partisan politics and that a significant correlation between Youth participation in politics and the peacebuilding process in Nigeria is well established. Now that the youth have been brought into political parties for more participation in the civic roles that they have been excluded from in the time past, there is a need for initiating programs and policies to better understand the roles of youth in political parties and the peace-building process. The study recommends that the Nigerian youth be properly enlightened and adequately equipped in peace and peace-building processes.

More and more, ports are moving towards environmental protection as economic performance is no longer the only criterion for competitiveness. Although contributing to global economic development, port activities can have negative impacts on coastal areas and marine biodiversity. This article presents the actions taken by the Port of San Pedro in the context of sustainable development. A qualitative methodology was used to study the port's sustainable practices, with the environmental manager being interviewed. The results show that the port, as a state authority, implements sustainable practices such as tree planting, environmental impact assessments, and the valorization of port waste into clean energy. In addition, several actions taken have resulted in the port obtaining various ISO certifications. Furthermore, the Port Autonomous de San Pedro is contributing to the momentum for environmental protection.
The Relationship Between Policy Rates and Domestic Debt in Ghana

Published: September 2023

The principal purpose of this study is to investigate the relationship between policy rates and domestic debt in Ghana. Utilizing a time series data, the study adopted the Vector Error Correction Model (VECM) for result analysis. Over the long run, domestic debt was found to have a negative impact on monetary policy rate, with the reverse observed for the short run. However, both models yielded statistically insignificant results. Nevertheless, the study revealed a statistically significant relationship between inflation and real GDP with the monetary policy rate in the long run, indicating a positive and negative impact, respectively. In the short run, only inflation was found to be statistically significant. The study's findings and analysis were found to be reliable as there was no evidence of serial correlation or heteroskedasticity in the model. In the end, the study was able to address a crucial gap in the literature on public debt by primarily investigating the influence of domestic debt on monetary policy rate in Ghana.
