Authors: Zhao Bin , Cao Wei , Zhang Jiqun , Gao Yilong , Li Bin , Chen Fengmei
Published: March 2024

Aiming at the issue that the current click-through rate prediction methods ignore the varying impacts of different input features on prediction accuracy and exhibit low accuracy when dealing with large-scale data, a click-through rate prediction method (GBIFM) which combines Gradient Boosting Decision Tree (GBDT) and Input-aware Factorization Machine (IFM) is proposed in this paper. The proposed GBIFM method employs GBDT for data processing, which can flexibly handle various types of data without the need for one-hot encoding of discrete features. An Input-aware strategy is introduced to refine the weight vector and embedding vector of each feature for different instances, adaptively learning the impact of each input vector on feature representation. Furthermore, a fully connected network is incorporated to capture high-order features in a non-linear manner, enhancing the method’s ability to express and generalize complex structured data. A comprehensive experiment is conducted on the Criteo and Avazu datasets, the results show that compared to typical methods such as DeepFM, AFM, and IFM, the proposed method GBIFM can increase the AUC value by 10% –12% and decrease the Logloss value by 6% –20%, effectively improving the accuracy of click-through rate prediction.
An intelligent stock trading decision system based on ensemble classifier through multimodal perturbation
Authors: Hou Xiaoyu , Luo Chao , Gao Baozhong
Published: March 2024

Candlesticks are widely used as an effective technical analysis tool in financial markets. Traditionally, different combinations of candlesticks have formed specific bullish/bearish patterns providing investors with increased opportunities for profitable trades. However, most patterns derived from subjective expertise without quantitative analysis. In this article, combining bullish/bearish patterns with ensemble learning, we present an intelligent system for making stock trading decisions. The Ensemble Classifier through Multimodal Perturbation (ECMP) is designed to generate a diverse set of precise base classifiers to further determine the candlestick patterns. It achieves this by: first, introducing perturbations to the sample space through bootstrap sampling; second, employing an attribute reduction algorithm based on neighborhood rough set theory to select relevant features; third, perturbing the feature space through random subspace selection. Ultimately, the trading decisions are guided by the classification outcomes of this procedure. To evaluate the proposed model, we apply it to empirical investigations within the context of the Chinese stock market. The results obtained from our experiments clearly demonstrate the effectiveness of the approach.
An adaptive model for smart grid evaluation using deep learning approaches
Authors: Mahendran S. , Gomathy B.
Published: March 2024

This study addresses the escalating energy demands faced by global industries, exerting pressure on power grids to maintain equilibrium between supply and demand. Smart grids play a pivotal role in achieving this balance by facilitating bidirectional energy flow between end users and utilities. Unlike traditional grids, smart grids incorporate advanced sensors and controls to mitigate peak loads and balance overall energy consumption. The proposed work introduces an innovative deep learning strategy utilizing bi-directional Long Short Term Memory (b-LSTM) and advanced decomposition algorithms for processing and analyzing smart grid sensor data. The application of b-LSTM and higher-order decomposition in the analysis of time-series data results in a reduction of Mean Absolute Percentage Error (MAPE) and Minimal Root Mean Square (RMSE). Experimental outcomes, compared with current methodologies, demonstrate the model’s superior performance, particularly evident in a case study focusing on hourly PV cell energy patterns. The findings underscore the efficacy of the proposed model in providing more accurate predictions, thereby contributing to enhanced management of power grid challenges.

Authors: Malik Indu , Baghel Anurag Singh , Bhardwaj Harshit
Published: March 2024

Herbicides, chemical substances designed to eliminate weeds, find widespread use in agriculture to eradicate unwanted plants and enhance crop productivity, despite their adverse impacts on both human health and the environment. The study involves the construction of a neural network classifier employing a Convolutional Neural Network (CNN) through Keras to categorize images with corresponding labels. This research paper introduces two distinct neural networks: a basic neural network and a hybrid variant combining CNN with Keras. Both networks undergo training and testing, yielding an accuracy of 30% for the basic neural network, whereas the hybrid neural network achieves an impressive 97% accuracy. Consequently, this model significantly diminishes the need for herbicide spraying over crops such as fruits, vegetables, and sugarcane, aiming to safeguard humans, animals, birds, and the environment from the detrimental effects of harmful chemicals. Functioning as the elevated API within the TensorFlow framework, Keras furnishes a user-friendly and immensely efficient interface tailored to address machine learning (ML) challenges, particularly in the realm of contemporary deep learning. Encompassing all facets of the machine learning process, from data manipulation to fine-tuning hyper parameters to deployment, Keras was meticulously crafted to expedite rapid experimentation.

Authors: Liu Zhiying , Yoon Sook Jhee , Zheng Maoxing
Published: March 2024

As a result of fast technical breakthroughs, globalization, a customer-centric emphasis, and team-based design techniques, 21st century workplace expectations for engineers have evolved. These changes need that engineering graduates possess highly developed critical thinking abilities in order to work at a high level in the engineering field. Critical thinking has been introduced as a fundamental ability in the new Skills Framework. Countries from all over the globe have taken steps to foster the development of critical thinking skills in their citizens, and researchers from a variety of fields pay attention to and conduct critical thinking research. However, comprehensive research on the teaching and learning of critical thinking in the Chinese setting is scarce. This study examines the research literature on critical thinking in Chinese classrooms in order to discover which theories and research methodologies are applied in critical thinking research. By scanning the CNKI and Web of Science databases, 63 Chinese and English publications were discovered using the PRISMA model. The analysis demonstrates that Chinese schools lack theoretical applications of critical thinking research. In the meanwhile, three distinct research techniques are used, however quantitative research approaches have the most papers. According to research, anyone interested in studying critical thinking should be familiar with its theory. In addition, researchers must use a range of study methodologies to guarantee that the results give information beyond summaries of critical thinking. Finally, Chinese researchers on critical thinking need greater exposure to qualitative data sources in order to modify their data gathering procedures.

Authors: Badiru Nafiu Isola
Published: March 2024

Purpose. The entrepreneurial activity has requirements that distinguish it from other professional activities, especially managerial activities and other requirements associated with recognizing business opportunities and engaging in innovative activity. Meanwhile, Entrepreneurial activities have been identified in the literature as drivers of SMEs’ growth and development. The study determined the mechanisms by which entrepreneurial activities impact the organisational innovativeness of Small and Medium Enterprises (SMEs) in Osun State, Nigeria. Design/Methodology/Approach. This study adopted a survey research design. The population of this study consisted of three thousand and seven (3007) Owners/Managers of registered SMEs in Osun State, Nigeria. The sample size of three hundred and fifty-three (353) for the study was arrived at using the Taro Yamane formula for sample size. This study employed a simple random sampling technique for the selection of respondents across all the three senatorial districts in Osun State. The primary data used for the analyses were collected from the respondents through the use of a structured questionnaire, and responses were analysed using descriptive and inferential statistics. Finding and Implication. Two hypotheses were proposed and tested. The first hypothesis revealed a significant impact of creativity at (R2 = 0. 982, β = 0.1.004, t = 90.701, p< 0.05) on SMEs organisational innovativeness and the second hypothesis revealed a significant impact of knowledge transfer at (R2 = 0.993, β = 0.1.012, t = 144.459, p< 0.05) on organisational innovativeness. Therefore, policymakers may be encouraged to develop and support policies that promote a creative culture and facilitate knowledge-sharing mechanisms among SMEs. Limitations. The study focuses only on entrepreneurs’ creativity, without recognizing the employee creativity. The study was also constrained by the cross-sectional and singlerespondent nature of the study. Originality. The claim about measuring performance with organisational innovativeness remains unclear to SMEs in Nigeria because most of the researches were carried out among large enterprises.

Authors: Velayutham Jeeven , Saniasiaya Jeyasakthy , Bin Abu Bakar Mohd Zulkiflee
Published: March 2024

Abstract. Introduction: Whitish lesion over the oropharyngeal mucosal lesion is traditionally attributed to benign lesions such as leukoplakia, oral candidiasis or lichen planus, which can be diagnosed through histopathological examination. Yet, performing a biopsy is prudent in all cases of persistent whitish lesions to rule out a more sinister pathology such as malignancy. Herein, we report an incidental finding of a whitish lesion in the soft palate of a gentleman who presented with otalgia and otorrhea, which turned out to be basaloid squamous cell carcinoma (BSCC). Therefore, we highlight the importance of thorough, meticulous and complete Ear, Nose and Throat examinations in all patients as they enable early diagnosis of a sinister pathology in this patient.

The Diagnostic Challenge of Distinguishing Temporal Lobe Encephaloceles from Sphenoid Sinus Mucoceles
Authors: Chin Ein Wan , Goh Liang Chye , Chong Aun Wee
Published: March 2024

Introduction: Temporal lobe encephaloceles are rare malformations defined as brain parenchyma herniation through a skull base structural defect into adjacent structure such as sphenoid sinus, while sphenoid sinus mucoceles are expansive cystic lesions caused by mucus buildup and thinning of the sinus wall, mostly involving the frontal and ethmoid sinus. Both illnesses may present similar clinical symptoms, such as neurological symptoms, nasal and ophthalmologic symptoms. However, misdiagnosis of temporal lobe encephaloceles can have significant clinical implications, as the best treatment plans vary depending on the disease. Case report: A 27-year-old healthy man who presented with seizure and loss of consciousness in public gave a history of head trauma 13 years back. Upon physical examination, the patient had normal cranial nerve function, and no cerebellar or meningitis signs. Rigid nasoendoscopy showed unremarkable findings. A computed tomography scan revealed an expanded left sphenoid sinus likely mucocele with a left temporal lobe encephalomalacia. Further investigations with brain magnetic resonance imaging (MRI) discovered temporal lobe encephalocele and transcranial repair of sphenoid encephalocele was arranged. Conclusion: Imaging results interpreted incorrectly may result in significant clinical ramifications. Distinguishing between both diseases with a complete investigation including MRI scan is crucial for appropriate management and treatment planning.

Published: March 2024

Objective: To determine the physicochemical characteristics and possible adulteration of raw milk marketed in dairy family systems located in the Atoyac River Basin in Puebla-Tlaxcala.
Design/methodology/approach: The physical characteristics of milk were determined: pH, acidity and freezing point; and chemical characteristics: fat, protein, lactose, minerals, non-fat solids, total solids and water content. This milk is produced and sold by 264 family production units to three cheese companies in the Atoyac River Basin in the states of Puebla and Tlaxcala. The data were analyzed by company and subsequently grouped with the Cluster technique of the SAS software.
Results: Significant differences (p<0.05) were found in the physical and chemical characteristics of the milk marketed by the producers with the three processing companies. In general, the milk is acid and adulterated with an average of 11.49% water; this results in a loss of $0.67/liter and in a dilution of its components, particularly protein and lactose, which leaves it outside the parameters established by normativity. The multivariate analysis generated four groups of producers and suggests the possibility that a group of producers adulterates with water, but also adds some kind of compound to increase the fat content to mask the adulteration.
Limitations on study/implications: The study of this topic, where the economic interests of the primary actors in the production chain can be affected, is delicate and difficult to carry out; however, it is necessary in order to know the quality of the products that are generated and their implication in the economy and the health of consumers.
Findings/conclusions: This study showed that the milk marketed by producers to processing companies does not comply with current regulations due to adulteration with water and the possible addition of compounds that replace fat; therefore, verification programs for compliance of the regulations are required, hoping with this that producers will receive a fair price for their production and will not have the need to adulterate the milk.

Objective: To evaluate the effect of the incorporation of Crotalaria juncea L. as green manure on the weed community in a cassava crop in Tabasco.
Design/methodology/approach: The study was carried out in the Experimental Field of Colegio de Postgraduados, Campus Tabasco (18º01' N and 93º03' W). The samplings were made on four dates: 1) at the planting of crotalaria (12/03/2018); 2) at flowering (31/01/2019); 3) 20 days after incorporation (22/02/2019); 4) at cassava harvest (25/04/2019), using metal squares 50 x 50 cm. Two planting densities, 50 and 80 cm (16,600 and 10,375 plants ha-1), two doses of NPK fertilization (160-40-80 and 00-40-80+GM), and a control were tested. The name of the species, number of individuals and coverage (percentage) were recorded to calculate the richness (S), Shannon diversity (H') and uniformity (E) indices, and the importance value index (IVI).
Results: The weed community consisted of 32 species, 28 genera and 16 families, of which the best represented are: Convolvulaceae, Asteraceae, Cyperaceae and Poaceae. The most frequently recorded species are Lindernia crustacea, Ludwigia octovalvis, and Ageratum houstonianum. The diversity indices reflected a poor community, especially with GM treatments; diversity ranged from low to medium and uniformity from medium to high. The importance of the families was more related to the environmental conditions than to the treatments; Cyperaceae were more important in the rainy season and Asteraceae in the dry season. L. crustacea appeared throughout the cycle.
Limitations/implications: It is advisable to extend the investigation period.
Findings/conclusions: The weed flora consisted of 32 species; the Convolvulaceae family was the most diverse and L. crustacea was the most recorded species during the cycle. The diversity indices reflected a poor community. The importance of the families was related to environmental conditions, where Cyperaceae stood out in the rainy season and Asteraceae in the dry season

Published: March 2024

Objective: The objective of this study was to carry out a bromatological and physicochemical analysis of local annatto seeds and a commercial paste.
Design/methodology/approach: The vegetal material used were local annatto seeds to which physicochemical analysis was carried out to determine ashes (Kirk et al., 1996), moisture (weight difference), dry matter (Nielsen, 2019), proteins (Kjeldah, AOAC, 1980), FDA and FDN (Van Soest and Wine, 1967), fat (Soxhlet, 1990). In addition, bromatological analysis was carried out on the samples and the commercial paste (Vázquez, 2001).
Results: The results obtained from the physicochemical analysis varied in ranges, where the M3 sample (dark heart-shaped annatto without filaments) presented the highest values. Regarding the bixin content, the highest percentage with 4.09 % was obtained in the M2 sample (heart-shaped red annatto without filaments) and the commercial paste was the lowest with 0.56 %.
Limitations on study/implications: The importance of carrying out the bromatological and physical-chemical analysis of the local annatto seeds was to determine which of the local samples and the commercial paste contain the highest amount of bixin. The antioxidant properties of bixin, together with a long shelf life in addition to its well-established safety characteristics, result in a very promising natural coloring agent in the food industry, given that it is an FDA-approved food additive: E160 b.
Findings/conclusions: The physicochemical analyzes varied in ranges, where the M3 sample (dark heart-shaped annatto without filaments) presented the highest values. The highest bixin content was found in the smooth heartwood red variety and the lowest value in the commercial paste.

Limitaciones en el estudio / implicaciones: La eliminación del medio ácido y el agua en la reacción fue un desafío en polioles con mayor índice de acidez.
Hallazgos/conclusiones: El método utilizado de extracción de grasa, permite obtener materia prima que cumple con las características para realizar la reacción de epoxidación e hidrólisis en un solo paso para obtener poliol. Las condiciones más severas de temperatura, concentración de catalizador, relación molar de dobles enlaces: ácido acético y tiempo de reacción, permitieron obtener la mayor cantidad de poliol de grasa avícola.Hidrólisis, grasa animal, epoxidación, residuos agroindustriales.

Authors: Flores Andrés , Corona-Ambriz A. , Méndez-González J. , Muñoz-Flores H. J.
Published: March 2024

Objective: To determine the phenotypic plasticity between fertilized (F) and unfertilized (UF) Q. variabilis seedlings developed in a nursery using small, medium, and large seeds.
Design/methodology/approach: By analyzing the phenotypic traits of growth (height and diameter at root collar) and root and stem dry biomass, plasticity indices and allocation patterns were assessed, and phenotypic traits in which the interaction effect of the seedling fertilization and seed size was observed.
Results: The results showed significant differences (p-value≤0.05) in the growth and biomass traits except for the root dry biomass, and significant differences were found both in the fertilization and seed size factors and in the fertilization and seed size interaction in phenotypic traits. For plasticity, all traits showed marked changes in response to the nutrient application, and small seeds had the highest plasticity indices. With respect to phenotypic change indices, medium seeds reached the highest values (0.94 for height and 0.92 for diameter). Large seeds recorded the highest index for root dry biomass (1.01), and medium seeds had the highest values of plasticity for stem dry biomass (0.81). Allometric differences were observed (intercepts were 1.8374 and 3.4956, and slopes were 4.0943 and 1.7038 for UF and F seedlings, respectively), and variations in the study factors (fertilization and seed size).
Limitations on study/implications: In order to improve the survival of plants in the field it is necessary to use seeds with high quality.
Findings/conclusions: Fertilization of Q. variabilis seedlings increases their biomass production, which allows for greater growth and survival compared to unfertilized ones.
Development and Implementation of an Advanced Therapeutic Communication Course: An Interprofessional Collaboration
Authors: Schwind Jasna , McCay Elizabeth , Metersky Kateryna , Martin Jennifer
Published: March 2024

Background: Interprofessional education and practice have been gaining recognition during the past decade. However, little has been written on person-centered care (PCC) within interprofessional practice and how it could be taught to interprofessional learners.

Method: A key element of PCC is therapeutic communication. Consequently, a group of interprofessional faculty innovated a graduate-level elective course on advanced therapeutic communication where interprofessional learners together explore PCC within interprofessional care. The course curriculum is underpinned by mindfulness in education, nonviolent communication, and reflective writing. Various teaching- learning strategies, including creative self-expression, are also used.

Results: The created competencies and conceptual framework may be used by other educators in creating a similar interprofessional course. Interprofessional learners gained a deeper and broader understanding of PCC in interprofessional care.

Conclusion: On the basis of this undertaking, the faculty gained a deeper appreciation for interprofessional collaboration in the development of innovative educational methodologies that advance interprofessional teamwork in education and professional practice. [J Nurs Educ. 2016;55(10):592-597.].
A Literature Review on the Application of IRB Chairperson Guidelines 4: â€œWomen Refugee Claimants Fearing Gender-Related Persecutionâ€ in Decision Making
Authors: Bah Haby
Published: March 2024

This paper examines Canadaâ€™s â€œWomen Refugee Claimants Fearing Gender-Related Persecution Guidelinesâ€ and its implications on women asylum seekers in Canada. Canadaâ€™s Women Refugee Claimants Fearing Gender-Related Persecution Guidelines were examined in order to get a better understanding of its impact on women seeking protection from gender based persecution. The first section of this paper looks at how certain refugee policies such as the Designated Country of Origin List and the Internal Flight Alternative have impacted women fleeing gender based persecution while the second

section discusses the implications of the guidelines on women asylum seekers refugee determination process. This paper provides background information on some of the unique forms of persecution that are specific to women and discusses the lack of womenâ€™s issues within international refugee law. Lastly, this paper provides ways in which the guidelines can be improved to better support women fleeing gender based persecution.

Keywords: gender based persecution, the Canadian refugee determination process, Canadaâ€™s Women

Older Syrian refugees' experiences of language barriers in post-migration and (re)settlement context in Canada
Authors: Boutmira Souhail
Published: March 2024

This research explores older Syrian (from the Government-Assisted Refugee program) experiences of language barriers in Canada's post-migration and resettlement context. Guided by the ecosystemic model (Guruge & Khanlou, 2004), the qualitative descriptive method (Sandelowski, 2000) was used to describe the experiences of six older adults (three women and three men, 55-year-old and over) living in the Greater Toronto-Hamilton Area. Results show that the lack of English proficiency affects refugees' resettlement and, in particular, older adults at risk of abuse. Language barriers influence older adult refugees because it limits their ability to navigate the Canadian systems, exacerbate their dependency on adult children, increase social isolation, and decrease employment and income opportunities. Participants' commitment to learning English comes from their conviction that fluency has an essential role in shaping their experiences in Canada. Conclusions can help policymakers identify specific interventions to address language barriers among older adult Refugees.
Remains of communism: an autoethnographic study of a Romanian-Canadian girl
Authors: Chesu Cezara
Published: March 2024

People migrate every single day and have been doing so since the beginning of the humankind. It is not something new, nor something out of the ordinary. That being said, all stories of migration are different depending on the push and pull factors of both the country of origin and the country of migration. Through this paper, I want to acknowledge my story and how it is different. I was born in post-communist Romania to a family that had lived their entire life in a wildly aggressive communist regime. I grew up in Romania in what was called a "democracy" at the time. My growing up however, was not democratic at all. Communism in Romania had never quite dissipated. While there is a sense that communism fell nearly overnight, in truth, the system was not so quickly dismantled. As a result, my entire childhood was influenced by the remains of communism.
Exploring the racial and gendered dimensions of Québecois secularism
Authors: Hussain Nooreen
Published: March 2024

This paper explores the specificity of Québec's secularism policies, practices and approach from a Critical Race Theory lens and problematizes apparent contradictions.

The recent passing of Bill 21 in Québec necessitates a re-examination of state secularism laws given the discriminatory impact on religious minorities, particularly veiled Muslim women. Specifically, this paper challenges the idea that these laws work to safeguard women's rights and argues that it indirectly accomplishes the opposite. An analysis of the political context highlights the centrality of secularism to conceptions of Québec'ss national identity, while the historical context reveals a complex relationship between Catholicism, religion, identity and secularism. Secularism measures from the past 15 years have carried significant racial and gendered undertones and has relied on a racializing discourse of the Islamic veil. This discourse is contextualized within the specific context of post-9/11 securitization where Islamophobia and anti-Muslim racism have become normalized.
Threats from Within and Threats from Without: Wetâ€™suwetâ€™en Protesters, Irregular Asylum Seekers and the On-Going Reproduction of Settler Colonialism in Canada
Authors: Perzyna Magdalena
Published: March 2024

This essay seeks to address the â€˜immigrant-Aboriginal parallax gapâ€™ by considering the ways in which the popular media frames Indigenous protesters and irregular asylum seekers. Using the work of previous studies of Oka/Kanasatake, Ipperwash and Caledonia and the irregular boat arrivals of Fujian and Tamil asylum seekers, it identifies similarities in the ways that each group was racialized, criminalized, delegitimized and constructed as the â€˜Otherâ€™ in the popular media. Employing the theoretical frameworks of settler colonialism and securitization theory, it goes on to examine whether the same frames persist in contemporary representations using the case studies of Wetâ€™suwetâ€™en protesters and irregular asylum seekers crossing the border at Roxham Road. A comparative discourse analysis finds that the media continues to frame Indigenous protesters and irregular asylum seekers as threats to the â€˜rule of lawâ€™ and the â€˜common goodâ€™,

reconstituting acts that are fundamentally rights affirming â€“ including the right to peaceful protest and the right to claim asylum â€“ into threats to Canadaâ€™s sovereignty, thus necessitating state action.

Preserving the â€˜Goldinâ€™ Age: Preparations of 35mm Slides for Exhibition
Authors: Marcello Julia
Published: March 2024

Â Â 

This project outlines a guide to preparing 35mm slides for exhibitions in cultural institutions with the case study focusing on Nan Goldinâ€™s The Ballad of Sexual Dependency. It highlights the development of The Ballad, helping to understand the artistâ€™s intent for the artwork, and places The Ballad within the lesser-explored canon of the history of projected photography. Using this research, the thesis lays out a detailed plan describing the steps taken to document the slides and to ensure that there is a complete record of what the artwork should look like at a proposed exhibition at the Art Institute of Chicago. This plan can then be applied to other slide-based artworks that are to be exhibited.
