Authors: Mboya Gaudensia John , Mwakalila Enock
Published: November 2024

This study assessed the factors affecting employee turnover in local government authorities (LGAs) in Dar es Salaam City Council, Tanzania. Specifically, the study sought to ascertain how motivational factors affect employee turnover in the Dar es Salaam City Council, to assess how hygiene factors affect employee turnover in the Dar es Salaam City Council, and to establish mitigation strategies to reduce employee turnover in the Dar es Salaam City Council.  A combination of qualitative and quantitative research methods was employed, utilizing a case study design to gain a comprehensive understanding of the phenomena. Primary data were collected through a survey method using a questionnaire and interview guide, involving 129 respondents who were randomly and purposefully selected from the Dar es Salaam City Council. The study was guided by two theoretical frameworks: the Existence, Relatedness, and Growth (ERG) Theory and the Conservation of Resources (COR) Theory. The analysis of the questionnaire data was conducted descriptively using the Statistical Package for Social Science (SPSS), with frequencies and percentages presented in tables, while the interview data were analyzed through content analysis. The findings revealed several factors contributing to employee turnover in LGAs, including low salaries and benefits, poor leadership and supervision, limited opportunities for training and development, delayed promotions and re-categorization, a shortage of working tools and infrastructure, job dissatisfaction, lack of incentives, and late or absent payments and other monetary rewards.  In conclusion, the study recommends that the management of LGAs in Tanzania, particularly the Dar es Salaam City Council, develop and implement policies aimed at improving the work environment to enhance employee retention.

Authors: Mtisho Grace , Rutenge Mary Mohamed
Published: November 2024

This study assesses the impact of political interferences in decision-making on the performance of one local government authority in Tanzania, Temeke Municipal Council. Specifically, this research had two aims: the first one was to identify areas where  political interference occurred most and the second was to assess the impact of political interferences on the social services delivery performance. In pursuit of the Wilson’s Orthodox theory in realization of classical models, this study adopted a case study research design and quantitative research approach. The study population was 358, comprising administrators and politicians. A simple random sampling method was used to select 97 administrators in the sample, while a purposive sampling method was used to select 1 Director and 91 politicians in the sample of 189 respondents. The data was collected through questionnaires and analysed quantitatively using descriptive analysis, Pearson’s Correlation and multiple regression analyses with the help of SPSS software. The study found that the political interference was statistically significant (with p ≤ 0.05) in hiring of technical experts, revenue collection & expenditure together with developing social services, and taking disciplinary measures. The research also found that the political interference in the decisions of local government namely budgeting and budget allocation, revenue collection and expenditure, developing social services, taking disciplinary measures, and reporting positively influence social service delivery at the Municipality. There were exceptions when it comes to the political interference in the hiring of technical experts as the results show that it negatively affects the social service delivery of the local government. The research concluded that the interference or rather the interaction between the politicians and administrators in the local governments should be guided by laws so as to tap the benefits which lead to the advancement of Temeke Municipality.

Authors: Ondieki Sarah Kwamboka , Korir Jackson C. , Hunja Carol W.
Published: November 2024

Population genetics analysis is a prerequisite to understanding how and why genotypes and allele frequencies and change over time between and within populations. Consequently, it offers insight into the process of evolutionary change and makes it possible to map variants linked to traits that differ among populations. In the present study, Single Nucleotide Polymorphisms (SNPs) markers were utilized to study the genetic characterization of 17 provenances from the Coast region of Kenya. 164 genotypes of Moringa oleifera were selected from 17 populations and genome sequencing undertaken utilizing genotyping by sequencing (GBS). Identification of polymorphisms (SNP Calling) in the selected genotypes and population genetic studies were carried out. SNP calling was done by Illumina’s SNP caller algorithm in the CASAVA software. 20,921 SNPs were called with an average call rate of 0.82. Average polymorphsm content (PIC) for the SNPs was 0.24 and reproducibility was 0.98. A phenetic tree was constructed using a neighbor-joining approach using DArT R. For the population genetics analysis, F statistic (Fst) utilising the functions StAMPP package in DArT R was performed whereby Gede and Samburu exhibited the least heterozygosity/correlation with a value of 0.0003 whereas Pwani University and Samburu had the highest correlation of genes at 0.37. Euclidean was used as a measure distance, and the average distance between the populations was 33.024. The molecular variance analysis (AMOVA) described a lower, 2.55%, variation within the population and 2.73% among the populations. The high similarity between the genotypes could be attributed to the Moringa plants in the various provenances having the same ancestry. This study may help identify links between gene allelic forms and phenotypes, allowing the alleles to be connected to desired characteristics such as rapid growth and high yield (functional analysis), because of the high frequency of SNPs and their role as a source of allele variations.

Authors: Adhiambo Beryl Teresa , Anyonje Lydia , Kabaji Egara
Published: November 2024

The COVID-19 pandemic occurred so unexpectedly and spread so fast that the media had to play its role of informing and educating the public about it. The people were in panic and the Kenyan government invested in strategies to address this like the daily speeches and text statements on COVID-19 through the available media for the masses. This saw media stations such as MMUST FM change tact to improve on their efficiency and thus new strategies of communication were adopted alongside the existing ones. The current study seeks to investigate the communication strategies adopted by MMUST FM from 2020 to 2021 to capture the attention of residents of Lurambi Sub-County regarding COVID-19 messages. The study was guided by the Framing Theory of mass communication. It adopted the descriptive survey research design where a mixed-method approach was utilized to collect, analyze and present data. The participants were 115 residents of Lurambi Sub-County as selected using Krejcie and Morgan’s formula with a confidence level of 95% for a population of 188,212 people. In addition, 6 key informants comprising 4 MMUST FM producers and 2 COVID-19 health experts interviewed by the station at the time were purposively selected for in-depth interviews. Data was collected using questionnaires from the residents and interview guides from the MMUST FM producers and the COVID-19 health experts. The validity of the qualitative data was achieved by establishing trustworthiness while the validity of the quantitative data was calculated using Cronbach Alpha Co-efficient calculations. A descriptive analysis of the quantitative data while a thematic analysis of the qualitative data was presented. From the study, we also realize that the station used communication strategies similar to the other media stations during other pandemics such as message consistency, honesty, the language used and how humanity and empathy were communicated while advocating for behavior change. However, the study reveals that the strategy that stood out with 103.9 MMUST FM is the radio program that was slotted to address the issues about COVID-19 when the pandemic was at its peak. This among the existing strategies helped the station successfully broadcast on the COVID-19 pandemic.

Published: November 2024

The purpose of this study was to determine education stakeholder’s perceptions on the effect of schools’ teaching practices on academic achievement in public secondary schools in Kakamega County, Kenya, The study was guided by School-Based Management Theory. A descriptive research design was used. The target population was 415 principals, 415 Deputy Principals, 415 directors of studies, and 33296 form four candidates of 2022. Stratified and purposive sampling technique was used. The sample comprised of; One hundred principals, 100 deputy principals, 100 directors of studies, and 400 students were chosen as the sample. The research instruments were; Questionnaires, an interview schedule, and document analysis schedule. Descriptive analysis was done using frequencies and percentages while inferential analysis was performed using Chi-square Analysis and Pearson product moment. Qualitative data was transcribed, analysed and reported according to emerging themes The Chi-square analysis indicated a significant difference between schools' teaching practices and academic achievement at a p value p < 0.05. The results indicated that there was a significant difference in their perceptions on the effect of schools’ teaching practices with regard to the effect of the academic achievement with the p value p < .001.The null hypothesis was consequently rejected. The findings indicate a notable disparity in the perceptions of education stakeholders, particularly students and deputy principals, regarding the influence of teaching practices on academic success in public secondary schools in Kakamega County. The p-value of p < .001 signifies a robust level of statistical significance, suggesting that the observed difference in perceptions is improbable to arise from random chance. As a result, the null hypothesis, which posited an absence of difference in perceptions, was dismissed. The evidence indicates a divergence in perspectives between students and deputy principals regarding the influence of teaching practices on academic performance. This may suggest that each group emphasizes or appreciates distinct facets of the pedagogical approaches, or that they possess diverse experiences and insights concerning the implementation of these practices within the educational environment. This implied that that the students and deputy principals perceived differently, the effect of the teaching practices on academic achievement. The study recommends that some teaching practices that were perceived to enhance academic achievement should be used in public secondary schools of Kakamega County.

Published: November 2024

Empirical studies have evidenced the correlation between vocabulary knowledge and English-speaking skills in various English as a foreign language (EFL) contexts but research is scarce in rural Rwandan schools. The present study evaluated the impact of senior five (S5) learners’ vocabulary knowledge on developing their English-speaking skills in three selected schools in the Gakenke District in Rwanda. The current study was guided by Harmer’s and Bygate’s vocabulary knowledge hypothesis and communicative competence theories for developing speaking proficiency. A quantitative descriptive research design was employed and cluster sampling was used to select 90 S5 learners from 116 who made the target population. A structured questionnaire was administered to assess the current status of vocabulary knowledge and English-speaking skills and the impact of vocabulary knowledge on English-speaking skills. Descriptive statistics was used for data analysis using MS Excel. Key findings revealed that 73.3% of learners regularly look up new vocabulary, and 100% reported having insufficient vocabulary. Additionally, 84.44% indicated that their speaking proficiency was low to moderate. Despite this low vocabulary knowledge, 95.56% of learners acknowledged that vocabulary enhances speaking skills. However, only 15.5% reported using new vocabulary frequently. Many learners (81.11%) felt that vocabulary development improved their self-expression, and 54.44% noted increased confidence in speaking English. Motivation was the highest-ranked factor influencing speaking skill development (M=4.40, SD=0.85), while assessment ranked lowest (M=2.96, SD=0.97). The study concluded that S5 learners in the selected schools have insufficient vocabulary knowledge to achieve the required level of speaking proficiency. The study recommended reinforcing vocabulary acquisition instructions and opportunities for learners to practice communicative English and assigns that future work should emphasize formal tests that examine English proficiency in correlational and experimental studies.
PATERNIDADE SOCIOAFETIVA: DO RECONHECIMENTO E SUAS CONSEQUÊNCIAS JURÍDICAS
Authors: Araujo Sâmilla Estrela de , Dantas Wellson Rosário Santos
Published: November 2024

O texto constitucional brasileiro traz entre seu ordenamento a pluralidade familiar, ou seja, as várias formações de família. Dentre essa variedade encontra-se a paternidade socioafetiva, ao qual se retira a ideia do estado filiativo que não advém da consanguinidade. Esse instituto traz consigo a alteração da ideologia do estado de filiação, demonstrando que a relação de pai/filho não está estritamente ligada a transmissão de genes. Frente a esse cenário, o presente estudo teve o objetivo de analisar a paternidade socioafetiva sob o ângulo social e familiar. Para além de sua análise, também se observará, o seu reconhecimento jurídico. Na metodologia, teve como fundamento uma revisão da literatura, baseada em artigos científicos, livros, periódicos, legislação atual e jurisprudência sobre o tema. A coleta de dados será realizada por meio de banco de dados tais como Scielo, Google Acadêmico, dentre outros, no período de 2018 a 2024. Nos resultados, ficou claro observar que dentro do ordenamento jurídico brasileiro a família formada pela paternidade socioafetiva encontra respaldo inicialmente na Constituição Federal de 1988 que abrange as formações familiares. Além disso, é possível encontrar respaldo no Estatuto da Criança e do Adolescente e na Lei 8.560/92, dentre outras normas. A paternidade socioafetiva caracteriza-se por três elementos: a publicidade, a continuidade e a ausência de equívoco na relação entre pai e filho. A jurisprudência tem se mantido favorável no reconhecimento da paternidade socioafetiva, desde que preenchidos os requisitos exigidos em lei e exteriorizada a devida relação.

Authors: Eyþórsdóttir Eyrún , Valdimarsdóttir Margrét
Published: November 2024

Scholars have described prejudice towards various minority groups as one of the negative characteristics of police culture. Visible prejudice within the police has serious consequences for trust and legitimacy, thus reducing the willingness of the public to cooperate with them. However, little is known about the attitudes of police students towards police work in a diverse society in the Nordic context. This paper focuses on newly recruited police students in the Icelandic police university program. Police students’ attitudes towards diversity are analyzed in the context of various possible work-related scenarios. The study is based on a survey of all newly recruited police students in Iceland, conducted yearly from 2018 until 2023. The findings indicate that police students are generally positive towards at least certain types of diversity measures in policing, although support for diversity has declined slightly in the most recent year.

Quais são os factores que contribuem na aplicação dos métodos activos no processo de ensino e aprendizagem, com enfoque ao método de trabalho em grupo? O objetivo do presente estudo é compreender as implicações do uso dos métodos activos no processo de ensino e aprendizagem (Trabalho em Grupo). Pretendemos apresentar um relato de experiência de ensino-aprendizagem por parte de alguns professores recém graduados dos IFPs da província de Niassa. Das experiências vividas nas escolas da província do Niassa em 2022, verificamos que 85% das aulas lecionadas, pelos recém graduados das escolas de formação de professores, aonde alguns deles não criam oportunidades ou espaços para os alunos aprenderem entre eles, sendo considerados alguns alunos como indivíduos inativos no processo de ensino-aprendizagem, contribuindo assim no enfraquecimento do raciocínio do aluno e no baixo rendimento pedagógico. Este fato contradiz as recomendações recebidas no acto da sua formação como vector fundamental o respeito pelo aprendente que é o aluno, e criação de espaço usando metodologias activas no sentido de fazer com que o aprendente tenha a capacidade de aprender a aprender, mas mediatizado pelo professor de modos que o aluno não seja visto como um que não sabe e que sem o professor na sala de aulas, ela torna-se inativo e sem nenhuma progressão.

Abstract
Optimization is needed by many people when there are two different parameters that must be achieved in conflict with each other, such as when a fisherman wants to get a large catch of fish with minimal operational costs. This is very confusing because if you want to get a lot of results, you have to spend a lot of operational costs too. However, getting large results and keeping operational costs low is a challenge for everyone. For this reason, there is a lot of research that discusses how to optimize algorithms to get the best results. This research reviews the optimization methods used to achieve that goal with different algorithms and different results. The results of this journal review are four methods in optimization research.

Yogyakarta is a city that has many sports facilities and types of sports. However, not all sports facilities are known by the people of Yogyakarta, especially for migrants from outside the city. So that a sports venue search mobile application is needed that can provide information about sports facilities, the need for sports facility information that can be accessed whenever and wherever the user is. Based on the above problems, it is proposed to create an android-based nearest sports venue search system. This system determines the location of the nearest facilities and infrastructure from the user's position by calculating the distance from two coordinate points and displayed on google maps and displaying the route to the nearest sports venue from the user. The result of this research is an android-based sports facilities and infrastructure location search application by utilizing GPS geolocation that can detect the coordinates of smartphone users and can display distances, road routes, and location updates. This application uses a data collection method by observation and identifying problems to test applications that are in accordance with community and functional needs. By utilizing Location-Based Services technology, it also increases the convenience of application users who want to exercise. After this sports venue search application is perfect, it will be able to run on the latest android or can run on ios for further features in the development of this application.

Washing is one of people's daily tasks that involves replacing dirty clothes with clean clothes, but not everyone can do it due to limited time, place to wash, and clothes. In addition, some weather factors can affect it. How quickly clothes dry depends on whether or not a washing machine is used. Pick-up service is a service that has been very helpful to the community because customers do not need to worry about the delivery of their goods. Laundry services are still very rare, which can cause difficulties for customers who do not have time to wash or bring it to the laundry. Overcoming the situation where customers have to deliver laundry themselves and solving the problems of previous research when the application only works on the Android operating system without knowing the location of the customer as well as problems with the Traditional Math payment system.

SQL injection attacks (SQLIAs) pose increasing threats as more organizations adopt vulnerable web applications and databases. By manipulating queries, SQLIAs access and destroy confidential data. This paper delivers three contributions around improving SQLIA detection research: first, a literature review assessing current detection/prevention systems to produce an SQL injection detection framework; second, specialized deep learning models optimizing session pattern analysis and feature engineering to enhance performance; third, comparing proposed models against previous defenses to surface promising research directions. Results highlight opportunities like real-time systems generalizing across attack variants through emerging techniques. Additionally, with attack complexity rising, systematized SQLIA investigation is warranted. Despite extensive study, current perspectives lack cohesive guidance informing mitigation strategies. Therefore, a framework is proposed holistically mapping knowledge gaps around contemporary SQLIAs, seminal threats in web applications, and security solutions. Furthermore, a multi-faceted framework examines research trends divided into hardening existing apps, detecting attacks on production systems, and integrating secure development practices. Literature suggests comprehensive resilience requires concurrent strength across these areas. Finally, future work remains in integrated frameworks, deep reinforcement learning adoption, automated AI auditing, and differential privacy to advance real-world SQL injection detection and prevention.

Pada artikel ini, penulis mengembangkan kerangka analisis kausal peristiwa kritis dalam penelitian studi kasus. Peristiwa penting didefinisikan sebagai peristiwa kontinjensi yang mempunyai dampak sebab akibat terhadap hasil suatu kasus tertentu. Penulisan ini menggunakan analisis teori himpunan untuk memberikan definisi dan alat pengukuran untuk menguji kontingensi dan signifikansi kausal dalam penelitian studi kasus. Seperangkat alat tersebut terdiri dari pedoman untuk menyimpulkan tingkat kontinjensi kejadian dengan menggunakan ekspektasi teoretis. Perangkat lainnya adalah pedoman untuk menggunakan kasus-kasus kontrafaktual guna menentukan sejauh mana peristiwa-peristiwa tertentu diperlukan dan cukup untuk menghasilkan hasil tertentu dalam kasus-kasus tertentu. Menyadari bahwa situasi akses jaringan menjadi sangat lambat. Praduga ada aktivitas yang tidak biasa terjadi di jaringan, dan aktivitas serangan mungkin telah terjadi. Untuk mengetahui penyebabnya, menganalisis hasil sniffing trafik menggunakan Wireshark. Dua kali penggalian data dilakukan pada waktu dan kesempatan yang berbeda. Menyelidiki kejadian tersebut dengan melakukan analisis pada data PCAP pada File Attack a.pcap atau Attack a.pcap. Hasil analisa dibahas dengan mengamati trafik yang dihasilkan pada jaringan dengan menangkap file PCAP.
