Authors: Utama Ria Fitri , Gustian  , Efendi Siska
Published: December 2023

Dharmasraya, a regency in West Sumatra Province, has traditionally focused on cultivating oil palm and rubber. However, due to a decline in prices for these commodities, there has been a shift towards cultivating cacao plants. Despite several years of cultivation, cacao production in Dharmasraya Regency remains low. This is attributed to unsuitable land and weather conditions, as well as the use of inferior plant material and uncertain origins of the cacao clone. To address these issues, a research study was conducted to assess the diversity and similarity of cacao plants in Dharmasraya Regency. The study focused on four locations within Sitiung Subdistrict: Siguntur, Sitiung, Gunung Medan, and Sungai Duo. A purposive sampling method was used to select the sample plants. The data was analyzed descriptively, and similarity analysis was performed using the NTSYS 2.02 software. The study identified seven different clones of cacao plants, each with distinct morphological characteristics in terms of leaves, flowers, fruits, and seeds. The phenotypic similarity analysis revealed a coefficient value ranging from 23% to 47%, indicating a moderate level of similarity, and a variability value ranging from 53% to 77%. It was found that qualitative traits exhibited a narrow range of variability, while quantitative traits displayed a broader range of phenotypic variability.

Authors: Waqar  , Shah Mukamil , Zia Manzar
Published: December 2023

This research investigates the intricate relationships between financial risk tolerance, personality traits, and demographic characteristics among investors in Lower Dir. By acknowledging the crucial role of these factors in shaping investment decisions, our analysis of 284 participants' data reveals that age, education, conscientiousness, and neuroticism significantly impact financial risk tolerance. On the other hand, gender, monthly income, openness to experience, and agreeableness show weaker or insignificant associations. These findings provide essential insights for devising effective financial planning and investment strategies. To further explore these relationships, future research should consider longitudinal or experimental approaches and larger sample sizes.
Pre-service Mathematics Teachers and Undergraduate Mathematics Students' Metaphorical Perceptions of the Concept of Mathematics
Authors: TEKE Bedirhan
Published: December 2023

Abstract: This study aims to compare the metaphors developed by the students of the Pre-service Mathematics Teachers (PMT) and the students of the Undergraduate Mathematics (UM) regarding the concept of mathematics and to determine how the metaphors are distributed as to the variables level of class and the department. For this purpose, hermeneutic phenomenology was used as a type of phenomenology design- one of the qualitative research methods. This study was conducted during the 2021/22 academic year with a total of 57 UM students studying at the Faculty of Arts and Sciences of a public university in the Southeastern Anatolia Region, and a total of 68 PMT students studying at the Faculty of Education at the same university. Data was collected through an interview form and analysed with content analysis. It was concluded that many metaphors are necessary in order to explain the concept of mathematics in a holistic way and that the respondents considered mathematics with its positive and negative aspects, as well as embracing it in daily life. It was also observed that the respondents’ perceptions of mathematics differ depending on the level of class and the department. For example, while the PMT students approached mathematics with a more concrete viewpoint, the UM students adopted an abstract mind-set. The reason for this result is believed to be related to the fact that the curricula applied for the PMT students contains less abstract expressions and theoretical lessons than that of the UM students, and also makes students active, offers a constructivist learning environment, and aims to train mathematics teachers rather than training them to become mathematicians.

Published: December 2023

Background: As awareness is the key tool for better prognosis, it is important for every kind of population. Being one of the most common cancers, also being associated with the high mortality rates, breast cancer awareness should be prevalent. As future doctors, medical students have the responsibility of educating the general population. To carry out such duties, they should possess enough knowledge about the subject. This study probes the extent of their knowledge.Methodology: An online questionnaire containing 15 questions of various formats was made and distributed to the students of Tbilisi State Medical University via E-mails. The collected data were processed in Microsoft Excel sheets. Answers from pre-clinical and clinical year students were analyzed separately.Results: A total of 225 responses were collected. More females (n=167) participated in the survey than males (n=56). A very low number of students selected correct answers to the epidemiological questions regarding the most common cancer among men, women, and the overall Georgian population. Despite attending awareness programs and having close contact with cancer patients, students showed a lack of awareness.Conclusion: There was no significant difference in knowledge or awareness noticed between pre-clinical and clinical students. Lack of knowledge despite having attended previous awareness programs and having close contact with cancer patients shows the lack of cognizance in students and their inability to retain information. This strongly indicates the need for more intensive activities on cancer awareness not only for students but also for the general population

Published: December 2023

The purpose of our article is to analyse the informal sector in Madagascar, in order to understand whether it is really a source of income. To do this, we carried out a representative survey of the fishing industry in the urban district of Toliara. The fishing industry has gradually taken its place in the overall economic organisation, and has now become an element of balance and a factor in social stability, and the basis of a territorial dynamic. On a national scale, it accounts for 7 per cent of gross domestic product, provides around 1.5 million direct and indirect jobs, and accounts for 6.6 per cent of exports, making it a fundamental sector of the economy. The main objective of this article is to provide, through various theoretical and empirical tests and analyses, some answers as to the real contribution of the informal sector to the financial integration of fishing households, in Madagascar in general and in the Urban Commune of Toliara in particular. The results of research among a sample of 250 fishermen in this capital of the Atsimo-Andrefana region confirmed that the informal sector offers stable financial resources.

Published: December 2023

The study mainly looked at the assessment of coping mechanisms against seasonal floods in Bumasheti Sub-County, Bududa District, Uganda. It identified the challenges affecting the coping mechanisms against seasonal floods in the area and it proposed solutions to the challenges.  Simple random sampling technique, using the lottery method was used to select the 41 primary respondents for the study, who included the local community members, that is, the local farmers, youth and the elderly in the community. Purposive sampling was used on the 16 key informants who included the local leaders and the sub-county officials like environment officer, and other officials in the area. Quantitative data analysis was based on 41 questionnaires for the local community members. Qualitative data was gathered from the key informant responses and focus group discussions. Quantitative data was analyzed using the Statistical Package for Social Sciences (SPSS). Content analysis was used to analyze qualitative data. The findings revealed that mechanisms in place to alert people about seasonal floods are largely poor in Bumasheti Sub-County, Bududa District, Uganda. The findings also revealed that, using the irrigation canals was preferred, compared to other coping mechanisms. The findings further revealed that the construction of flood protection embankments is to a greater extent less relevant to the local populace in terms of coping with seasonal floods. The findings also revealed that flood plain zoning restriction on use of plains is not an appropriate coping mechanism for the area. The challenges affecting the coping mechanisms against seasonal floods in Bumasheti Sub-County, Bududa District identified by the study included: difficulty to repair cracks, loss of lives, difficulty to predict floods in this part of the world and the effect of steep area on the land. The proposed solutions to the challenges included the construction of safe place for food, clean water and basic necessities, defense against the spread of floods, disassociation from building under the hills and hard lands, constant watch to monitor water levels during the night and utilization of the indigenous knowledge passed down by parents. The study recommends that tight restrictions/rules be set which restrict settlement by people on those areas prone to flooding so as to prevent the negative impacts that might result to death.

Authors: Pascal Aka KOFFI Blaise
Published: December 2023

La problématique de l’environnement a aujourd’hui totalement investi toutes les préoccupations mondiales. Cette révolution culturelle débute dans les années 1970 avec la prise de conscience écologique. Pour résoudre ces problèmes environnementaux, l’un des moyens est la pratique de l’éducation environnement. Cette étude vise à mettre en lumière les facteurs qui limitent l’adoption d’un comportement environnemental chez les élèves des établissements secondaires publics du district autonome d’Abidjan. Une approche mixte mobilisant les techniques et outils de collecte de données sociologiques dans les lycées modernes d’Abobo, de Cocody, de Port-Bouët et de Yopougon-Andokoi, a permis d’identifier les représentations sociales et les pratiques environnementales des acteurs chargés des questions environnementales de la direction de la vie scolaire et des établissements, de mettre en évidence les stratégies de gestion environnementale mises en œuvre et de décrire le processus de construction de la conscience environnementale des acteurs (élèves et personnels administratifs) autour de la question de l’environnement. Après analyse, il ressort que les représentations sociales que se font les acteurs, les pratiques environnementales et la conscience qu’ils construisent autour de l’environnement ne permettent pas l’adoption d’un comportement écocitoyen chez les élèves des établissements secondaires publics du district d’Abidjan.

Published: December 2023

The purpose of this study is to descriptively analyze the extent of Integrated Pest Management (IPM) and non-IPM practices in Kampar District, Kampar Regency. This research uses a descriptive method aimed at gathering information through questionnaires, direct observations, and interviews. The subjects of the study consisted of 38 IPM rice farmers and 62 non-IPM rice farmers. The results of the study indicate that both IPM and non-IPM farmers in Kampar District have implemented practices for cultivating healthy crops. The distinguishing factor between IPM and non-IPM farmers lies in pest and disease control. IPM farmers consistently monitor their fields as the basis for making decisions on pest and disease control measures. IPM farmers use superior and locally superior seeds, while non-IPM farmers predominantly use local seeds. IPM farmers prioritize preventive measures in pest and disease control, resorting to the application of chemical pesticides only when the infestation reaches an economic threshold. Non-IPM farmers control pests and diseases using chemical pesticides periodically without considering the level of infestation. The participation of farmers in IPM programs and farmer groups influences their adoption of healthy crop cultivation practices and IPM. Non-IPM farmers perceive pest and disease control using chemical pesticides as more practical and yielding quicker results. However, they are not aware that the indiscriminate use of chemical pesticides increases production costs, poses risks to themselves and the environment. This lack of awareness contributes to the low adoption rate of IPM among farmers.

Published: December 2023

Multiple sclerosis (MS) is an immune system demyelinating and neurodegenerative disease of the central nervous system, and the main source of non-traumatic neurological disability in young adults. Successful management requires a complex way to deal with control acute attacks, manage progressive declining, and remediate bothersome or handicapping side effects related with this disease. Striking advances in treatment of all types of MS, and particularly for relapsing disease, have well changed the long-term outlook for some patients. There likewise has been a calculated change in figuring out the immune pathology of MS, away from a simply T-cell interceded model to acknowledgment that B cells play a vital part in pathogenesis. The rise of higher-efficacy drugs requiring less frequent administration have made these favoured choices with regards to tolerability and adherence. Numerous specialists currently suggest utilization of these as first-line treatment for some patients with early disease, before long-lasting handicap is evident.

Published: December 2023

La pratique du « kwlan » occupe une place importante dans la communauté traditionnelle ivoirienne notamment chez le peuple Baoulé de oualêbo. En revanche, ces pratiques sont contrariées par les politiques sanitaires en matière de lutte contre certaines pandémies à cause du risque de propagation de maladies comme le VIH/SIDA et des IST. Fort de cette réalité, nous avons trouvé juste de mener notre recherche sur les ‹‹ Représentations et pratiques sociales de la morale sexuelle à l’épreuve des IST et VIH/SIDA dans la ville de Sakassou : Cas du « kwlan » chez les Baoulés de « Oualêbo › ›. Pour mener à bien ce travail ; nous avons eu recours à des outils de l’approche qualitative comme le guide d’entretien, la recherche documentaire, le focus groups pour collecter les données. Il ressort de cette étude que la population de Sakassou pratique toujours le « kwlan » malgré l’existence du VIH/SIDA/IST dans la localité et surtout les campagnes de sensibilisation contre cette maladie. Plusieurs éléments expliquent la pratique du « kwlan » chez les Baoulé de Oualêbo. En effet, la recherche de responsabilité probable de la femme dans le décès de son conjoint, la libération ou rupture des liens entre la femme et le conjoint défunt et l’insertion sociale de la veuve demeurent les facteurs motivationnels qui cristallisent la pratique du « kwlan » dans ce milieu où le taux du VIH/SIDA est relativement élevé. L’analyse de cette question s’inscrit dans le prolongement de la théorie de la représentation sociale pour comprendre les mécanismes de maintien de cette pratique et surtout les logiques qui justifient l’acceptation par les femmes de cette pratique bien que connaissant les conséquences sociales et sanitaires.

Authors: Robertson Boye Arab , Inoussa Toko Mouhamadou , Issiaka Bonssara
Published: December 2023

The inability of existing transfer stations in Greater Monrovia, Liberia, to handle municipal solid waste collected daily from designated collection points for temporary storage and final disposal has resulted in a number of issues such as abandonment of overfilled skip buckets and reinforced concrete bins, indiscriminate waste disposal into drainages, along roadside, river banks, and so on. This situation has also resulted in a number of negative consequences, including environmental degradation, public health concerns, depreciation of the value of adjacent properties, and decrease in the quality of life of the population. The local authorities have made relentless efforts to secure funding through its international partners to construct a well-designed municipal solid waste transfer station, However, due to the study area's topographic complexities, it is difficult for them to select an ideal site for a municipal solid waste transfer station to collect waste from designated and illegal collection points on time. To solve this issue, the research will analyze and identify potential sites while keeping the environment and population within the study area in mind. The research employs a comprehensive evaluation of multiple factors, including lithology, slope, drainage density and land use through GIS tool like Analytic Hierarchy Process (AHP) to identify potential sites that meets sustainable waste management’s requirements. The results showed that 43% of the study area is not suitable, 20% is least suitable, 20% is moderately suitable, 11% is suitable and 6% highly suitable for an environmentally-friendly transfer station. Central Monrovia A and B, and Northwest of Paynesville are areas identified to be suitable for municipal solid waste transfer station.

Nous avons utilisé des déchets de PET comme liant et des graviers de granite comme renfort dans la fabrication de pavés perméables à l’eau et à tout fluide de viscosité dynamique voisine de celle de l’eau.Le matériau composite ainsi obtenu correspond à une « valorisation matière » des déchets de PET et est surtout une alternative à la lutte contre l’imperméabilisation des sols urbains. Il s’agit là d’un matériau de construction du Génie civil relativement récent.Les pavés ainsi fabriqués sont dotés de forte porosité (23 à 37%) et de perméabilité élevée (1,3 à 3,6cm/s). Leur résistance à la compression satisfaisante fait de ceux-ci un matériau directement exploitable et utilisable pour le recouvrement des sols dont principalement les aménagements sans contraintes de trafic (cours intérieures, trottoirs, jardins, aires de jeux, etc.).Le taux de liant, les classes granulaires des renforts, la porosité sont généralement les facteurs prépondérants qui influencent les comportements de pavé plastique perméable à l’eau.Ce matériau est aussi intéressant non seulement sur le plan social et sociétal, mais également sur le plan environnemental, ce qui contribue naturellement au développement durable.

La présente étude vise à évaluer la diversité de la faune ichtyologique de la rivière Kwilu dans sa partie comprise entre le port Louise et le pont Kwilu dans la ville de Kikwit, République Démocratique du Congo. L’échantillonnage des poissons a eu lieu entre janvier et août 2020 à l’aide de plusieurs engins de pêche. Les paramètres physico-chimiques des eaux de surface de cette rivière se situent dans la gamme des valeurs pouvant favoriser la survie des poissons. Au total, 301 spécimens de poissons appartenant à 43 espèces,  regroupées dans 32 genres, 17 familles et 9 ordres ont été identifiées. Les indices de diversité (richesse spécifique et Shannon et Weaver) ont montré que la faune de poissons exploitée dans tronçon le tronçon de la rivière Kwilu est riche, diversifiée et régulièrement repartie. Les poissons Siluriformes (23,5%), Characiformes et Osteoglossiformes (17,6%) ainsi celui des Anabantiformes (11,8%) sont les plus abondants. Au niveau des familles, les poissons Mormyridae (19%), Cichlidae (13%), Alestidae, Claroteidae et Distichodontidae (avec 9% respectivement) sont les plus nombreuses. Les poissons des genres Clarias et Hemichromis (9%), Alestes, Brycinus, Tylochromis, Petrocephalus et Schilbe avec respectivement 5% sont les plus nombreux. En terme d’abondance numérique des espèces de poissons inventoriées, Congothrissa sp (31 individus soit 10,29%), Brycinus imberi et Clarias angolensis (15 spécimens soit 4,98%), Auchenoglanis occidentalis (14 individus soit 4,65%), Clarias gabonensis (13 individus soit 4,31%) et Alestes lateralis (10 individus soit 3,32%) représentent un grand nombre d’individus dans l’échantillon et, Barbus sp (1 individu soit 0,33 %) est faiblement représenté. Compte tenu du rôle que joue la rivière Kwilu dans l’approvisionnement de poissons frais dans la ville de Kikwit, il est important de préserver et valoriser la faune ichtyologique de cette région à travers une gestion durable et participative.
The Effect of Strength Based Parenting Mediated by Emotion Regulation on Adolescent Delinquent Intentions

Published: December 2023

Strength-based parenting is a parenting approach that focuses on identifying and developing children's strengths. Parents who apply strength-based parenting tend to have teenagers with a high awareness of their potential and positive character. In the next stage of development, this will enable adolescents to use their strengths to face challenges, rather than getting trapped in delinquent behavior. This study aims to examine the effect of strength-based parenting on delinquency intention, with emotion regulation as the mediator. A total of 418 adolescents from 3 high schools in Medan City were selected as research subjects using simple random sampling method to collect data on strength based parenting, emotion regulation, and delinquency intention. Structural Equation Model (SEM) was used as a data analysis method. The results showed that strength based parenting did not affect delinquency intentions, but it had a positive and significant effect on emotion regulation, and emotion regulation had a negative and significant effect on delinquency intention. Emotional regulation fully mediated the relationship between strength based parenting and adolescent delinquency intentions.This study contributes to understanding the factors that influence adolescent delinquency intentions and provides insights for parents, teachers, and the community to focus on optimizing adolescent strength and emotional regulation abilities to prevent them from engaging in delinquent behavior.

Ceiba pentandra (L.) Gaertn. is one of the cotton-producing plants. However, there is a population decline in some areas, resulting in a decrease in genetic variation. This study aims to determine intrapopulation and interpopulation genetic variation and genetic differentiation of C. pentandra in three populations in West Sumatra. The research was conducted with the descriptive method using molecular data and sample collection with the survey method. Analysis of genetic variation using RAPD (Random Amplified Polymorphic DNA) markers on 15 individual plants collected from three populations, namely Solok, Pesisir Selatan, and Padang Pariaman. The results showed that primers OPA-01, OPA-02, and OPB-10 could detect polymorphism. The value of intrapopulation genetic variation was highest in the South Coastal population (H = 0.1857) and lowest in the Solok population (H = 0.1228). Interpopulation genetic variation (DST = 0.0326) was lower than intrapopulation genetic variation (Hs = 0.1607), with a low genetic differentiation value (GST = 0.1686) and a high gene flow value (Nm = 2.4660). Cluster analysis showed that the Pesisir Selatan and Solok populations had the farthest genetic distances (0.0580). UPGMA analysis shows that accessions do not cluster specifically based on their population.
