Portfolio investing, a compelling subject for businesses and individuals, revolves around stocks as a high-return but inherently risky financial instrument. This study delves into the characteristics of stocks, emphasizing the need for investors to comprehend stock dynamics and trading approaches. Amid diverse investment avenues, the pursuit of positive returns is universal, acknowledging the inherent risk in any investment. Notably, equity investments are perceived as riskier than debentures and bonds. Risk is dissected into systematic and unsystematic categories, with the former being uncontrollable and the latter diversifiable. The CAPM functions as a predictive instrument, shedding light on the connection between the risk of an asset and its anticipated return. Utilizing analytical research and secondary data, this study synthesizes information from various sources, offering insights into portfolio management. Keywords: Capital Asset Pricin

Authors: Journal IJSREM
Published: February 2024

Using repetitive arrangements of precision resistor networks in a ladder-like shape, an R-2R Ladder is a quick and low-cost approach to do digital-to-analog conversion. Different resistor levels, an operational amplifier (LM741), and single pole double throw switches were the major building blocks for both circuits. MULTISIM software was used to build both circuits so that the circuit could be tested for its ideal use. The inclusion of both circuits in a real circuit helps with identifying and contrasting each's strengths and drawbacks. Using repetitive arrangements of precision resistor networks in a ladder-like shape, an R-2R Ladder is an easy and affordable approach to accomplish digital-to-analog conversion. The use of Multisim to implement R2R DAC fills the gap between theoretical and practical circuits. Using Multisim, this study presents an accurate, detailed representation of a 3 bit and a 4 bit R2R ladder. The binary's R 2R ladder circuit, which has a percentage inaccuracy of 4.16%, was discovered. Keywords—R2R Ladder, DAC, Staircase, Multisim

Abstract—Nowadays, the majority of people utilise social networking sites on a daily basis. Numerous people create profiles on social networking websites every day and connect with others there, regardless of their location or time. False identities are used in additional malicious operations in addition to playing a significant part in advanced persistent threats. Users of social networking sites can benefit from them, but they also have to worry about the security of their personal information. We must first determine the user's social network accounts before we can determine who is endorsing threats in these platforms. Social media usage has dramatically increased in recent years, according to statistics. Social networking sites have made things easier as they allow us to connect to people effortlessly and converse with them without the requirement for physical meetups. One of the major issues with Online Social Networks (OSNs) is fake interaction, which is used to artificially boost an account's popularity. Because phoney involvement causes businesses to lose money, inaccurate audience targeting in advertising, inaccurate product prediction systems, and an undesirable social network atmosphere, its detection is essential. Based on the classification, it is required to distinguish between real and phoney profiles on social media.Several categorization techniques have traditionally been used to identify phoney social media accounts. However, there are ways to improve social media's ability to detect phoney profiles. The suggested effort uses technology and machine learning to boost the percentage of predicted phoney profiles. Chi-square technique is used in feature selection models to find the best data. The several machine learning methods, including the Logistic Regression and Random Forest algorithms, are used in the classification approach. The classification outcome based on recall, sensitivity, specificity, f1-score, accuracy, and precision.

Personalising Learning in Maltese - Exploring International Students’ Expectations Towards Ġabra Online Lexicon
Authors: Żammit Jacqueline , Camilleri Patrick
Published: February 2024

The rapid incorporation of digital technologies in formal education has led to significant transformations, albeit not always yielding the anticipated productivity. This study investigates the attitudinal changes towards an online Maltese lexicon, Ġabra, among 46 adult learners of Maltese as a foreign language. By utilising a composite analytical model, the study is grounded in the theoretical frameworks of Technological Frames of Reference, the Technology Acceptance Model (TAM), and the Unified Theory of Acceptance and Use of Technology (UTAUT). These frameworks guided the tracking of the development of respondents’ attitudes over a five-month research period. The survey results gathered at the onset and conclusion of the study highlighted a perceptual discrepancy between the initial expectations towards an e-dictionary and the actual usage experience of the Ġabra platform. As the students gained more experience with the platform, their attitudes towards Ġabra underwent a shift. Despite some initial expectations not being fulfilled, the majority of students ultimately found Ġabra to be a beneficial tool for learning Maltese. The students’ feedback about the Ġabra online dictionary can potentially pave the way for a more personalised learning experience of the Maltese language.

Published: February 2024

Crude palm oil, extracted from the mesocarp of the fruit of the oil palm (Elaeis guineensis Jacq.), is the world’s most widely produced and consumed vegetable oil. However, the food quality of this oil is influenced by its acidification and the negative effects associated with this acidity. Recent work on progenies from the DA 115 D of the Deli population and LM 2 T of the La Mé population involved in seed production has shown variability in oil acidity within and between these progenies, suggesting the possibility of selection to improve palm oil quality in these progenies. To improve the quality of the oil produced in Côte d’Ivoire, progeny from crosses between double self-fertilized progenitors of DA 115 D and LM 2 T origins were evaluated. The acidity of these progenies was determined using the near infrared spectrometer (NIR). The results showed that 4 progenies were homogeneous with low acidities (acidity < 5%) and 9 progenies were heterogeneous with low and medium acidities (5% < acidity < 10%). In addition, only offspring from combinations involving LM 2509 D AF were homogeneous. As a result, the average acidity of each progeny was all below 5%.
Impact of Microdosing Practices on Technical Efficiency: An Analysis Accounting for Selection Bias Among Smallholder Maize Farmers in Burkina Faso
Authors: Sawadogo Didier , Matsumura Ichizen , Esham Mohamed , Fernandez Cristhian , Elias Asres
Published: February 2024

Smallholder maize farmers are currently confronted with the arduous challenge of managing limited financial resources while incessantly facing the issue of land degradation. To address this issue, an alternative solution has been implemented to optimize the use of chemical fertilizer by adopting microdosing. This innovative system not only helps them enhance their agricultural productivity but also allows them to protect the environment. However, it is unclear how microdosing adoption could increase the technical efficiency (TE) of maize production. Therefore, this research aims to assess how the adoption of microdosing affects the technical efficiency of maize production as well as identify the key factors that influence the technical efficiency of maize production in Burkina Faso. To achieve this goal, farm household survey data was conducted with 210 randomly selected farmers from the Plateau Central and northern regions of Burkina Faso. To account for potential selection biases that could result from both observable and unobservable factors, we used a sample selection stochastic production frontier model and a propensity score matching approach. A stochastic meta-frontier approach was applied to estimate TE differences and the technology gap between adopters and non-adopters. The findings showed that adopters of microdosing have an average efficiency of 68 percent, which is higher than the 53 percent estimated for non-adopters. Adopters of microdosing have been found to have high TE and better agricultural technology than non-adopters. The meta-frontier estimation revealed that the adoption of improved maize varieties would yield better returns. This study contributes significantly to the literature on how fertilizer microdosing affects maize productivity, as well as the policy implications of targeting and encouraging smallholder maize farmers in Burkina Faso to optimize the use of productive inputs and improve maize output by using microdosing.

Authors: Soltani Nader , Willemse Christian A. , Sikkema Peter H.
Published: February 2024

New weed management strategies are needed to effectively control multiple-herbicide-resistant (MHR) Canada fleabane in corn. Five experiments were established in growers’ corn fields with confirmed MHR Canada fleabane to determine the efficacy of various herbicides applied preplant (PP). In 2021 environments, glyphosate + isoxaflutole + atrazine, glyphosate + isoxaflutole/diflufenican + atrazine, glyphosate + S-metolachlor/atrazine/mesotrione/bicyclopyrone, glyphosate + mesotrione + atrazine, glyphosate/dicamba + isoxaflutole/diflufenican, glyphosate/dicamba + isoxaflutole/diflufenican + atrazine, and glyphosate + saflufenacil/dimethenamid-p provided excellent control (90-100%) of MHR Canada fleabane but glyphosate + S-metolachlor/mesotrione/bicyclopyrone and glyphosate + S-metolachlor/atrazine/mesotrione controlled MHR Canada fleabane 77-84% and 87-96%, respectively at 4, 8, and 12 weeks after application (WAA). Herbicide tankmixes evaluated reduced MHR Canada fleabane density and biomass 91-100%. In 2022 environments, all glyphosate tankmixes evaluated provided 97-100% control, 99-100% density reduction, and 100% biomass reduction of MHR Canada fleabane in corn. In 2021 and 2022 environments MHR Canada fleabane interference reduced corn yield 41 and 32%, respectively; reduced MHR Canada fleabane interference with all herbicide treatments resulted in corn yield similar with the weed-free control. Results of this study indicate that glyphosate + isoxaflutole + atrazine, glyphosate + isoxaflutole/diflufenican + atrazine, glyphosate + S-metolachlor/atrazine/mesotrione/bicyclopyrone, glyphosate + mesotrione + atrazine, glyphosate/dicamba + isoxaflutole/diflufenican, glyphosate/dicamba + isoxaflutole/diflufenican + atrazine, and glyphosate + saflufenacil/dimethenamid-p provide excellent and consistent control of MHR Canada fleabane. However, glyphosate + S-metolachlor/atrazine/mesotrione and glyphosate + S-metolachlor/mesotrione/bicyclopyrone do not provide consistent control of MHR Canada fleabane in corn.

The objective of this study was to describe the use of complementary imaging tests to aid diagnosis in cases of hydrocephalus in the canine species. A female canine, of the Shih-Tzu breed, approximately three months old, weighing 2 kg, was seen at the Unicentro veterinary school clinic, with the main complaint of not playing and not responding to auditory or visual stimuli. The patient had pain when palpated in the cranial region, as well as pain in the topography of the cervical spine. The animal was sent for imaging exam. On radiographic examination, an enlarged skull was observed with soft tissue radiopacity in the frontal bone area, associated with bone discontinuity in the anatomical topography of the frontal fontanelles. On transcranial ultrasound, anechoic areas located inside the brain were detected, as well as an increase in the dimensions of the lateral ventricles filled with anechoic content. The report was indicative of hydrocephalus. The present study showed the effectiveness of transcranial ultrasound examination and cranial radiographic examination in diagnosing hydrocephalus. Being an alternative to veterinarians, since computed tomography and magnetic resonance imaging are high-cost exams and these methods are often unavailable, depending on the region.

Published: February 2024

Real-time electroconductivity monitoring is important in several industry instances. However, this monitoring in aqueous solutions or suspensions (e.g. mineral slurries), applying direct current, is problematic due to electrode polarization, which is the accumulation of ions at the electrode-solution interface. In this study, a low-cost circuit developed is based on Arduino, allowing real-time measurement. It has annular electrodes and operates at a frequency of 1.0 kHz, simulating an alternating current signal, in order to diminish the deleterious effect of interfacial polarization and electrolysis on the electrodes. Through calibration using standard KCl solutions, a measurement range of 0.002 S/m to 1,000 S/m was obtained with good accuracy and precision. Its use is exemplified here by predicting the porosity of suspended binary granular systems.

Cowpea (Vigna unguiculata L. Walp.) is a crop of great socioeconomic importance in the Northeast region of Brazil, being a generator of employment and income for thousands of people and a source of proteins, minerals, diet fibers and bioactive compounds, which help in the prevention of various diseases. This work aimed to evaluate the nutritional and cooking quality of grains from different commercial classes of cowpea. Raw and cooked grains from 10 cowpea genotypes were evaluated. The proximate composition and total energy value (TEV) were determined, according to AOAC; iron (Fe), zinc (Zn) and selenium (Se) contents, by ICP-OES; phytic acid content by method 986.11 AOAC; and cooking quality, using an electric pressure cooker and Matsson cooker. The nutritional and cooking quality index (IQNC) was estimated, considering proteins, Fe, Zn, Se, and cooking quality as positive characteristics and the phytic acid content as a negative characteristic. Genotype means were grouped using the Scott-Knott test (p<0.05) and raw and cooked grains using Student's t test (p<0.05). There were significant differences between genotypes for all traits except for proteins and carbohydrates in raw grains. Cooking increased protein content in genotypes IT97KD-1042 and BRS Olhonegro, and Zn, in all genotypes, and reduced phytic acid by 10.43 to 30.64%. Cooking quality was greater than 52% for all genotypes. The cultivars BRS Tumucumaque, BRS Imponente and BRS Olhonegro, both belonging to the white commercial class, highlighted with the highest IQNC. These cultivars can be used in programs aimed at combating malnutrition and confirm the nutritional value of cowpea and the quality contribution it can provide when included in a balanced diet.

Residential submarkets in traditional central areas: new spaces and property obsolescence in Recife
Authors: Bernardino Iana Ludermir
Published: February 2024

The central areas of Brazilian cities have acquired an increasing importance in the dynamics of capitalist production of space, either through the construction of new real estate or through the ressemantization of old real estate. In Recife, the intensification of the production of residential real estate in the immediate surroundings of the historic sites listed over the decades of 2000 and 2010 has added, to the stock built up in the central area, real estate with typologies similar to those already practiced in other districts. The present paper shows how the real estate market of new residential properties - corresponding to contemporary consumer desires - and the used real estate market are articulated in order to unveil how the residential real estate submarkets are configured. The behaviors of the bidders and consumers, the means of disclosing the available properties, pricing, the strategies for comparing the available properties and the attributes praised by bidders and valued by consumers are substantially differentiated so that, even located in proximity condition, units can enter into different submarkets with their own operating mechanisms.

This study aims to understand the positions of elementary school students in Coimbra/Portugal on the processes of development of PE, gender and the reflection of these positions in the classroom. To construct the corpus, semi-structured interviews were used with 16 students from two elementary school in the city of Coimbra/Portugal. The analysis shows that although the students are reflective about PE and concerned about equal opportunities, non-sexist practices and language, there are still contradictions and marks that reinforce a non-genderized or binary and hierarchical reality about gender, contributing to the circulation of social discourses of female inferiority. Therefore, students are fundamental to changing this unequal reality, as their beliefs and perceptions shape behavior and give meaning to the daily life of school PE.

Published: February 2024

Matopiba region is considered the main agricultural frontier in Brazil currently, with the expansion of areas suitable for agricultural activities intensifying since the 2000s, causing changes in land use and land cover (LULC) in the region. This study aimed to analyze changes in LULC in the Matopiba region from 1985 to 2020 and identify the spatial dynamics that occurred with the expansion of agricultural activities. To assess the changes in LULC, scenarios obtained from the Mapbiomas database between 1985 and 2020 were used. The area was divided into pre-established classes by Mapbiomas, including the Agriculture class. The dynamic modeling of these scenarios allowed for the evaluation of losses and gains in LULC classes during the assessed period due to the expansion of agricultural activities. The 2020 scenario of the Matopiba region provided by Mapbiomas was used as a reference to assess the ability of the dynamic modeling used to estimate scenarios. The results demonstrate that areas designated for agricultural activities increased by 14.77% between 1985 and 2020, with the largest expansion observed in the period from 2005 to 2015 (4.81%). The scenario estimated by the dynamic model showed similarities to the reference scenario, demonstrating the ability of dynamic modeling to simulate and analyze the spatial dynamics of regions and estimate future scenarios.

Nilalayon nitong maihanay ang paralelismo ng TG (Teachers Guide), LM (Learning Module) at CG (Curriculum Guide) sa isa't isa; mailarawan ang lawak ng nilalaman at pamamaraan at kasanayan na nakapaloob sa modyul na kaugnay sa ika-21 siglong kasanayan na dapat taglayin ng mag-aaral; mabakas ang mga problema na kinaharap sa modularisasyon ng Filipino sa K-12; at makapagmungkahi ng angkop na modelo sa pagsasagawa ng isang ebalwasyon para sa kagamitang panturo na tutugon sa ika-21 Siglong Kasanayan. Upang maisagawa ito, nagsagawa ng focus group discussion sa mga guro ng dalawang paaralang gumagamit ng modyul. Gayundin ay sinipat at sinuri ng mananaliksik ang mga gawain ng modyul kung ito ay tumutugon sa ika-21 siglong kasanayan. Mula rito, nalaman na hindi nakatutugon ang nasabing kagamitang panturo sa ika-21 siglong kasanayan ngunit para sa mga guro na gumagamit nito ay lubos naman silang sumasangayon na may bahagi ng modyul na makikitaan ng ika-21 siglong kasanayan. Batay sa mga datos na nakalap ng mananaliksik, bumuo ang mananaliksik ng Modelo ng balwasyon para Kagamitang Panturo na Tutugon sa Ika 21 Siglong Kasanayan. Iminumungkahi ng pananaliksik na gamitin ito sa nalalabi pang mga modyul sa Filipino na ginagamit sa K 12.ABSTRACTThe research focuses in assessment of modules in K-12 for Filipino subjects. The objectives are the following: (1) To see the parallelism of Teacher's Guide, Learning Modules, and the Curriculum Guide to each other; (2) to describe the scope of the content, strategy and skills in the modules based on the 21st century skills; (3) To trace the problem in using the modules in Filipino; and lastly to suggest appropriate model to evaluate a teaching materials based on the 21st Century Skills. The researcher used Focus Group Discussion for teachers in the two high schools that uses the modules. The researcher also analyze the activities in modules if its suited for the development of 21st century skills. Based on the findings of the study the researcher develop an Evaluation Model for Teaching Materials Based on the 21st Century Skills. The researcher suggest to used the said model for the other modules in Filipino.

This is a quasi-experimental study on the effect of teaching with the use of non-math analogies on achievement in and attitude towards mathematics of students from two sections of a college institution in Manila as respondents. Mathematics Achievement Test (MAT) and Attitude towards Mathematics Inventory were administered as pre- and posttests, and the data collected were interpreted using t-tests. Results revealed comparability of the two groups prior to the conduct of the experiment. Further, the achievement of students taught with the use of non-math analogies improved better than those taught without non-math analogies. Likewise, the learning experience of students with nonmath analogy seemed to have a positive significant effect on their attitude towards mathematics. Students find learning with non-math analogy easier, more meaningful, and more enjoyable because they could relate the abstract concepts in mathematics to what they experience in reallife. Consequently, mathematics teachers are encouraged to use non-math analogies in teaching mathematics asa strategy that could help their students appreciate and  better understand the lessons.
Development and Validation of Instructional Modules on Rational Expressions and Variations
Authors: Torrefranca Evelyn C.
Published: February 2024

Modular instruction is an attempt to individualize learning by allowing a student to achieve mastery of one unit of content before moving on to another. Module, as a self-instructional material, can be used as a supplementary material to help the student improve his/her mastery and as means to help the student catch up with the missed lessons. In this study, instructional modules on two content areas of Algebra taught to second year high school students were developed and validated. Specifically, module 1 consisted of 11 lessons on Rational Expressions, and module 2 consisted of nine lessons on Variations. Findings revealed that all the evaluators strongly agreed that the instructional modules satisfied the criteria for evaluating the modules. Meanwhile, the significant change in the pretest and posttest scores of student-participants before and after they were exposed to the modules signify that the modules brought out improvement in their knowledge of Rational Expressions and Variations. Possible replication of the study to cover other topics in Intermediate Algebra is recommended to further support the findings that emerged.

The study explored the effectiveness of combined interventions in facilitating the students' lacklustre academic performance in Science. Twenty Grade 6 students at risk during the first semester of the school year 2015-2016 at F. Guerrero Elementary school were the participants of the study. Remedial classes in Science and a series of home visitationswere done to assist the participants and their engagement in class–assigned activities. Pre-test and post-test were administered to gauge the contribution of the combined interventions to the improvement of the academic performance of the participants. Results revealed that providing remedial classes to students at risk is still one of the most effective means of facilitating learning, complementing this with follow up efforts through home visitations confirmed theimportance of parental involvement in students' education. The narrative analysis of the conversations between the teacher and the parents showed the need for teachers to continuously reach out to parents to promote a more open communication between the school and the home. The study has indeed reinforced existing literature on the relevance of home visitseven in this age of advanced technology.
Self- and Teacher-Assessment of Science Process Skills
Authors: Santos Melandro D. , David Adonis P.
Published: February 2024

This study aimed to assess both basic (BSPS) and integrated science process skills (ISPS) level of proficiency among selected grade ten technical-vocational students. The study also examined the feasibility and value of utilizing the developed SPS assessment tool that supports the “assessment for learning” in teaching science. To measure the SPS level of proficiency, an instrument was developed based on the performance-based indicators of process skills (Miller 2006). After participating in science laboratory activities, the students assessed their SPS level of proficiency individually. Data were collected from the students' activity outputs, worksheets and self- and teacher-SPS score sheets. Findings revealed that the performance of subjects in the overall SPS was “average”. When categorized into basic and integrated process skills, the subjects showed “proficient” basic SPS (BSPS) and “average” integrated SPS (ISPS). There was no significant difference between the student and teacher assessment on both basic and integrated SPS. The results support the feasibility and value of utilizing an SPS score sheet as an assessment tool in addition to the performance rubrics for formative assessments. It was observed that the disclosure of students' progress and SPS level of proficiency made the students more focused in improving their SPS skills rather than their numerical grades. Based on these findings, the researchers advocate daily assessment of SPS and the use of both teacher and self-assessment of SPS  as alternative or adjunct strategies in the assessment of SPS.

The general objective of this study was to analyze First Prize Winners in Short Stories for Children that won in the Palanca Literary Awards from 2001-2010. This research used a descriptive method of study and was made to find out if the winners ofPalancahave the characteristics based from the concept given by Norton (2003), Lukens (1995), and Mcguire (1882) which give emphasis on the significance of literary elements in analyzing a short story. These were also seen in the literary criticism given by Glazer (1997) which is the text-focused and context-focused approach. Based from the result of this study, the researcher found out that it is very important to have an analysis and evaluation on the materials that the student's are using in the class. Based from the principles that were used in the study, the researcher has also created an instrument that will be used in evaluating the content of children's short stories. Having a prior evaluationis very essential to assureit's that appropriatenessto the targetreaders and use it a supplement/ instructional materials for teaching. It is an important contribution in helping the teachers who are using this kind of genre.ABSTRAKPangunahing layunin ng pag-aaral na ito na masuri ang mga kuwentong pambata na nagwagi ng unang gantimpala sa Gawad Palanca mula taong 2001-2010. Ang pananaliksik na ito ay isang deskriptibong pag-aaral na isinagawa upang matuklasan kung ang mga nagwaging kuwentong pambata ay nagtataglay ng mga katangiang naaayon sa pamantayan nina Norton (2003), Lukens (1995), at Mcguire (1982) na nagsasaad na mahalaga ang pagbibigay-diin sa mga elementong literari sa pagsusuri ng isang kuwento. Ang mga ito ay nakapaloob din sa ginamit na dulog sa panunuring pampanitikan ni Glazer (1997) na text-focused at context-focused approach. Batay sa kinalabasan ng pag-aaral na ito, natuklasan ng mananaliksik na mahalaga ang pagsusuri ng mga akdang ipinagagamit sa mga mag-aaral. Mula sa mga nakuhang simulaing naging batayan ng pag-aaral, nakabuo rin ang mananaliksik ng isang instrumentong maaaring gamitin bilang pamantayan sa pagsusuri ng mga maikling kuwentong pambata. Mahalaga ang pagkakaroon ng panimulang ebalwasyon upang matiyak ang kaangkupan nito sa mga mambabasa at magamit bilang suplemento/ kagamitang pampagtuturo. Ito ay mahalagang ambag na makatutulong ng lubos sa mga gurong gumagamit ng mga genre na kagaya ng mga kuwentong pambata.

The study investigated and analyzed the Aboriginal Teacher Education Program (ATEP), Faculty of Education, University of Ottawa as basis in the development of indigenous peoples education curriculum for the Philippine Normal University-North Luzon, the indigenous peoples education hub. Data gathering procedure included document analysis, surve,y and interview. The respondents included the director, assistant director of teacher education, six faculty and one alumna of the University of Ottawa, Ontario, Canada. The conceptual framework is anchored on active, collaborative inquiry of reflective practice. The ATEP is both campus and community-based. A variety of assessment techniques were used in evaluating the program. The program reflects researches in teacher education and ethical standards of teaching profession of Ontario. ATEP courses have fewer contact hours than baccalaureate education program. Ontario College of Teachers certify ATEP graduates to teach in primary, junior to Grade 6. Moreover, graduates receive greater career opportunities nationally and abroad. Integration of indigenous knowledge and issues during instruction depends much on the professor. Other  universities in Canada are more grounded and focused on indigenous education and have better enrolment in aboriginal teacher education program than the University of Ottawa.
