THEORETICAL MODELS OF CONSUMER BEHAVIOUR: A LITERATURE REVIEW
Authors: Manuere Henry Takudzwa , Chikazhe Lovemore , Manyeruke Josphat
Published: May 2022

The purpose of this study is to present the evolution of theories that have influenced consumer buying decision processes in a unique way. Consumer behaviour is the study of how individual customers or groups of organisations, select, buy, use, and dispose ideas, goods and services to satisfy their needs and wants. Marketers use theories of consumer behaviour to explain how consumers behave and to segment the market for consumers. Marketers make use of several theories of consumer behaviour, namely, traditional theories and contemporary theories. Traditional theories are based on economic principles or experiences of marketers, whereas modern theories are associated with empirical results. The concept of empirical means something that can be observed or measured. The theory of consumer behaviour is an explanation of facts in an orderly manner. However not all theories of consumer behaviour are good or sound. A sound theory of consumer behaviour describes both behaviour and the nature of the behaviour. Thus consumer behaviour theories are used to understand and predict the behaviour of consumers. To that end this study makes use of two important groups of theories, namely, the Buyer Behaviour theory and the theories of reasoned action. These theories will help us to conduct research on different aspects of consumer behaviour. Therefore the strengths and weaknesses of these theories are documented.
SPOTLIGHTING RAPE CULTURE IN GHANA THROUGH THE LENS OF DRAMA
Authors: Brew Faustina , Nukpezah Patience
Published: May 2022

This paper projects the deep-rooted veracity of rape culture in Ghana. Rape barely comes up in mainstream discourse in Ghana and there are no significant efforts to address this pervasive menace. Reported rape cases are often swept under the carpet and hardly sustained to logical conclusions. Victims are either blamed or stigmatised if they speak up and often, preventive overtures on rape are limited to cautioning girls to be careful not to get raped. In a bid to openly engage in conversation and examine the entrenched reality of rape culture in Ghana, we directed Danso Sakyi’s play, You Raped Me, which highlights rape culture in Ghana. The play presents a controversial rape case in which the audience forms the jury to pronounce judgement after the accuser and accused are heard. Selected members of the audience were engaged in open forum discussion on why the culprit should be convicted or reasons to declare the victim’s story incredible. With the play as a stimulus, the pertinent subject of rape was discussed offering an appreciable depth of insight into society’s views on rape culture in Ghana. This paper illuminates the contents of the play in relation to rape culture and discusses the views of the respondents. The findings showed that rape culture is really entrenched in Ghana and people will believe or disprove one’s claim of rape based on engrained biases of who raped, who got raped and the circumstances of the rape.

Authors: Bellfkih El Mehdi , Nouh Said , Idrissi Imrane Chems Eddine , Louartiti Khalid , Mouline Jamal
Published: May 2022

Many research papers in coding theory have recently focused on designing high-rate codes or improving codes that exist through a better understanding and then improving the coding and decoding algorithm. As a result, this paper aims to investigate the computation of the Automorphisms groups of some optimal codes (e.g., some linear circulant codes where their distance meets the lower bound and nonlinear Nordstrom-Robinson (24, 28, 6) code). These Automorphisms groups provide information about the structure of the code, which aids in both the design and enhancement and improvement of decoding algorithms. A new genetic algorithm-based method is proposed, with a detailed description of its components, the fitness function, selection, crossover, and mutation, and is used to find an important collection of Automorphisms; the results obtained have shown that the proposed method is effective in finding stabilizers set for some types of codes.

Authors: Baiduri  , Cholily Yus Mochamad , Ulfah Fithria
Published: May 2022

Intuitive thinking is one approach that can be done in solving mathematical problems. This study aims to analyze the process of the emergence of intuitive thinking of high-ability students in solving mathematical problems related to number patterns in terms of gender. This research is a descriptive study using a qualitative approach with four class X students with high mathematical abilities, each of two male and female students used as research subjects. Research data was obtained through written answers and interviews with subjects. Credible data was obtained through time triangulation and was analyzed by interactive methods. The results show that the emergence of intuitive thinking in male subjects uses an extension of intuitive thinking flow with a construction strategy. This extension of thinking involves two components of intuitive thinking, feeling, and intervention. In contrast, the emergence of intuitive thinking on female subjects uses intuitive thinking with the strategy of guess and test. Intention thinking flow involves two components of intuitive thinking, feeling and intrinsic. The novelty of our studies demonstrated that gender differences in students determine the method of solving the problem, especially more pronounced in the guessing and re-checking stage, involving the intention thinking flow in female and construction strategy in the male participants.

First, the thirty-three compounds from plants of the genus Spatholobus were analyzed using the PASS server to obtain information about compounds that have breast cancer biological activity above 75%. Second, the thirteen selected compounds were evaluated using the STITCH server to determine their interactions with various proteins involved in apoptotic pathways and p53 signaling. Third, the thirteen breast anticancer compounds were re-selected to get pharmacological properties for safe consumption with the SwissADME server. Lastly, the selected nine compounds were further docked with target protein caspase-3 using the PyRx 0.99 tool and visualized with PyMol 2.5.2 and BIOVIA Discovery Studio Visualizer 2.1.1.0.2098. In conclusion, the nine compounds (lupinalbin A, trigraecum, coumestrol, maackiain, medioresinol, isoliquiritigenin, 8-O-methylretusin, biochanin A, and medicarpin) from the genus Spatholobus are predicted to have potential as activating agents for the caspase-3 protein and can suppress the growth of breast cancer cells.

Although most mechanized forestry work relies heavily on cranes for handling logs along the supply chain, there has been little research on how to improve cranes design. In addition, the available research has mainly focused on improving current designs, so there is a lack of application of modern methods for designing cranes with improved efficiency.This paper analyzes how a mechanical engineering design method, known as gravity compensation, can be used to make a new generation of highly energy efficient forestry cranes. To introduce this design approach, a standard forwarder crane with two booms is used as a model system on which to apply gravity compensation concepts. The design methodology follows a procedure based on physics and mathematical optimization, with the objective of minimizing the energy needed to move the crane by using gravity compensation via counterweights. To this end, we considered to minimize mechanical power, because this quantity relates to how fuel and hydraulic fluid are converted into mechanical motion.This analysis suggests that using gravity compensation could reduce energy consumption due to crane work by 27%, at the cost of increasing the crane total mass by 57%. Thus, the original crane mass of 559 kg increases to 879 kg after applying gravity compensation with counterweights. However, overall reductions in energy consumption would depend on both the crane work and the extraction distance. The greater the extraction distance, the lower the total savings. However, energy consumption savings of around 2% could be achieved even with an extraction distance of 1 km.From a design perspective, this study emphasized the need to consider gravity compensation in the design philosophy of forestry cranes, not only for its ability to minimize energy consumption, but also due to all the inherited properties it provides. This initial study concludes that designing cranes with a combination of gravity compensation concepts could yield a new generation of highly energy efficient cranes with energy savings exceeding those reported here.

Based on the generated database of 413 and 490 plots of biomass of Populus spp. and Betula spp. in Eurasia, statistically significant changes in the structure of forest stand biomass were found with shifts in January temperatures and average annual precipitation. When analyzing harvest data, the propeller-shaped biomass patterns in the gradients of average annual precipitation and average January temperatures are obtained, which are common for both deciduous species. Correspondingly, Populus and Betula forests show a regularity common to the biomass components: in the cold zones the precipitation increase leads to the increase of biomass, and in the warm ones to their decrease. In wet areas, the increase of temperature causes the decrease of biomass, and in dry areas, it causes their increase. In accordance with the law of the limiting factor by Liebig-Shelford, it is shown that both an decrease in temperature in dry conditions and a increase in precipitation in a warm climate lead to a decrease in the biomass of trees.
COVID-19 Lockdown: Impact on PM10 and PM2.5 in Six Megacities in the World Assessed Using NASA’s MERRA-2 Reanalysis

Published: May 2022

The changes in air quality were investigated in six megacities during the shutdown phases in 2020 and were compared to the same time periods in the previous 10 years (2010–2019) using the data of Modern-Era Retrospective Analysis and Research and Application, version 2 (MERRA-2). The concentrations of PM10 and PM2.5 were greatly reduced in all megacities during the lockdown in 2020 when compared to the same period in 2019 and in the previous ten years. The highest reduction in PM10 was recorded in Delhi, and São Paulo (21%, and 15% and by 27%, and 9%), when compared with the concentrations in 2019 and in the period 2010–2019, respectively. Similarly, levels of PM2.5 in Delhi, São Paulo, Beijing, and Mumbai decreased by 20%, 14%, 12%, and 10%, respectively in 2020 when compared to the last ten years. Results indicated that the lockdown is an effective mitigation measure to improve air quality. The MERRA-2 reanalysis dataset could be a vital tool in air quality studies in places with a lack of In-situ observations.
École des Sciences de l’Information (Rabat-Maroc) : Évolution ou révolution de son identité ?
Authors: Bahji Salah Eddine
Published: May 2022

Durant l’année 1975, le Maroc a lancé son École des Sciences de l'Information (ESI), seule institution nationale de formation des professionnels de l’information.
L’histoire de cette institution a été marquée par plusieurs réformes. La toute dernière remonte à 2016, lui attribuant le statut d'École d'ingénieurs, pour former des ingénieurs des contenus (données et information), des connaissances et des systèmes d’information.
Ce virage entrepris par l'ESI pour embrasser la Science des Données et les Sciences de l'Information est dicté par plusieurs facteurs de changement, conduits par l’évolution de l’objet d’étude et des technologies disruptives qui ont élargi les domaines de spécialisation.
En effet, les principaux facteurs de changement résident dans : (1) Le changement de l'objet d’étude « Information » et la massification des données ; (2) Le changement de l'usage et de l'usager ; (3) L’évolution de la mission de médiation qui doit s’adapter aux nouveaux objets/usagers.
Ce papier tente ainsi d'expliciter le processus d'évolution qu'a connu l'École des Sciences de l'Information pour asseoir sa nouvelle identité.
Abstract
In 1975, Morocco launched the School of Information Sciences (ESI. The only national institution for the education of Information Professionals.
The last reform experienced by the ESI occurred in 2016, granted it the status of Engineering School, training engineers in the field of content (Information and Data), Knowledge and Information Systems Engineering.
This decisive shift undertaken by the School to embrace Data Science and Information Sciences is dictated by several factors of change, driven by the disruptive technologies that have revolutionized our fields of specialization.
We summarize these factors in three areas of change: (1) Change of the object being processed “Information” and the massification of Data; (2) Change of use and user behavior; (3) Change in the mission of the Mediation.
This paper tries to explain the process of change and evolution that the School of Information Sciences has experienced, through an agile approach to build its new identity.
