An Intelligent Missing Data Imputation Techniques: A Review
Authors: Seu Kimseth , Kang Mi-Sun , Lee HwaMin
Published: July 2022

The incomplete dataset is an unescapable problem in data preprocessing that primarily machine learning algorithms could not employ to train the model. Various data imputation approaches were proposed and challenged each other to resolve this problem. These imputations were established to predict the most appropriate value using different machine learning algorithms with various concepts. Furthermore, accurate estimation of the imputation method is exceptionally critical for some datasets to complete the missing value, especially imputing datasets in medical data. The purpose of this paper is to express the power of the distinguished state-of-the-art benchmarks, which have included the K-nearest Neighbors Imputation (KNNImputer) method, Bayesian Principal Component Analysis (BPCA) Imputation method, Multiple Imputation by Center Equation (MICE) Imputation method, Multiple Imputation with denoising autoencoder neural network (MIDAS) method. These methods have contributed to the achievable resolution to optimize and evaluate the appropriate data points for imputing the missing value. We demonstrate the experiment with all these imputation techniques based on the same four datasets which are collected from the hospital. Both Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) are utilized to measure the outcome of implementation and compare with each other to prove an extremely robust and appropriate method that overcomes missing data problems. As a result of the experiment, the KNNImputer and MICE have performed better than BPCA and MIDAS imputation, and BPCA has performed better than the MIDAS algorithm.

Published: July 2022

Image captioning research, which initially focused on describing images factually, is currently being developed in the direction of incorporating sentiments or styles to produce natural captions that reflect human-generated captions. The problem this research tries to solve the problem that captions produced by existing models are rigid and unnatural due to the lack of sentiment. The purpose of this research is to design a reliable image captioning model that incorporates style based on state-of-the-art SeqCapsGAN architecture. The materials needed are MS COCO and SentiCaps datasets. Research methods are done through literature studies and experiments. While many previous studies compare their works without considering the differences in components and parameters being used, this research proposes a different approach to find more reliable configurations and provide more detailed insights into modelsâ€™ behavior. This research also does further experiments on the generator part that have not been thoroughly investigated. Experiments are done on the combinations of feature extractor (VGG-19 and ResNet-50), discriminator model (CNN and Capsule), optimizer (Adam, Nadam, and SGD), batch size (8, 16, 32, and 64), and learning rate (0.001 and 0.0001) by doing a grid search. In conclusion, more insights into the modelsâ€™ behavior can be drawn, and better configuration and result than the baseline can be achieved. Our research implies that research in comparative studies of image recognition models in image captioning context, automated metrics, and larger datasets suited for stylized image captioning might be needed for furthering the research in this field.

Published: July 2022

Online reviews are crucial for business growth and customer satisfaction. There is no exception for the airlinesâ€™ company, which places third as the biggest contributor to Malaysiaâ€™s Gross Domestic Product. Customer opinions play an important role in maintaining the reputation and improving the quality of service of the airlines. However, there is no specific platform for online review. Most online ratings obtain English, leading to inaccurate results as not all reviews regarding different languages are considered. Airlines currently have no specific platform for online reviews despite being critical for business growth, performance, and customer experience improvement. Hence, this paper proposed implementing a web-based dashboard to visualize the best Malaysian airline companies. The airline companies involved are AirAsia, Malaysia Airlines, and Malindo Air. We designed and developed the proposed study through the bilingual analysis of Twitter sentiment using the NaÃ¯ve Bayes algorithm. NaÃ¯ve Bayes algorithm is a machine learning approach to do classification. The tweets extracted were analyzed as metrics that advance airline companiesâ€™ online presence. Testing phases have shown that the classifier successfully classified tweetsâ€™ sentiment with 93% accuracy for English and 91% for Bahasa. Every feature in the web-based dashboard functions correctly and visualizes a detailed analysis of sentiment. We applied the System Usability Scale to test the studyâ€™s usability and managed to get a score of 94.7%. The acceptability score â€˜acceptableâ€™ result concluded that the study reflects a good solution and can assist anyone in understanding the public views on airline companies in Malaysia.

Published: July 2022

As a pivotal supporting arm and the driving force to ensure better healthcare services, the Hospital Information System (HIS) provides the backbone support for efficiently managing the hospital's operations and services. Against the backdrop of the current economic situation and the uncertainties in the grim global economic outlook, it is crucial to optimize the cost of the information system while meeting the objectives. This paper contributes to introducing a technique to optimize the public Hospital Information System funding in Malaysia. It explores the prolonged financial viability of the HIS in Bintulu, East Malaysia, through e3Value methodology. The e3value methodology can evaluate the financial sustainability of HIS projects and can serve as a tool for early requirement analysis on future HIS deployment. From the e3value model, it is interesting to discover that actors contribute positive revenue to the hospital, allowing the hospital to generate more profit, which benefits the Government. However, actors that give negative revenue might affect future financial status. Based on the result, the recommendations presented in this paper are very crucial to ensure the continued financial sustainability of HIS. The e3value model offers early requirement study analysis and structured analysis with systematic approaches compared to the existing method. Although the work can measure the financial sustainability of the HIS, other sustainability dimensions like technological sustainability, environmental sustainability and social sustainability are yet to be explored and worth investigating in the future.

The educational system in Brazil, especially the high school level, is characterized by a division, offering a general and humanist formation for the economic elite, and direct preparation for labor, for the working-class. Aiming to overcome this duality and contribute to the polytechnic formation of vocational education students, this paper presents and analyzes interdisciplinary teaching activities that discuss the relationships between Industry 4.0 technologies, production systems, and education. The educational product, developed and applied based on the action research methodology, consisted of identifying the students' prior knowledge, three units of teaching activities, and a final evaluation questionnaire. According to the students' background and their suggestions, the content and didact methodology of each unit was selected, including the history of industrial revolutions, technologies arising from Industry 4.0 (internet of things, data mining, and cloud computing), the challenges of the fourth Industrial Revolution on the economy and labor. Didact methodologies include dialogic lecture based on slides, hands-on practical activity experimenting Industry 4.0 technologies through free online applications, and debate. Interdisciplinary activities were developed at the Federal Institute of Education, Science and Technology of São Paulo, involving students of the 4th year (last) of high school integrated into vocational education with a qualification in Industrial Automation. During the application it was observed that the use of educational product led to considerable levels of motivation and promoted reflections related to the impact of the Industry 4,0 technologies in society and employment. Also, it has been verified that the didact sequence increases the student capacity to: identify problems and propose possible solutions; understand labor different dimensions (technology, employment, politics, and economics); use strong argumentation based on reliable sources, proposing possible interventions. Thus, the interdisciplinary approach of technological development, considering not only the technical concepts but also the historical and sociological issues related to the application of technologies in the productive system, contributes to a critical teaching-learning process and the omnilateral formation in vocational education.

The purpose of this study is to produce a performance-based assessment instrument to stimulate students' critical thinking in welding quality testing courses. The ability to think critically occurs when you understand the material given. Performance-based assessment can be done on the process and learning outcomes. The method used in this study is the Borg and Gall method with ten steps of development. The practice of welding quality testing has an analysis orientation that results in an acceptance decision on the welding quality. The results are validated in terms of content, language, and constructs by specified experts. The results of the performance-based assessment design use five stages, namely: determining the underlying problem, creating an assessment context, determining the assessment rubric, carrying out a performance assessment, and formulating the assessment results, and responding to the evaluation results. The rubric used is a rubric with a scoring form. The instrument design is following the task of the inspection of welding results. The output of welding quality testing learning is a report containing observations results and making decisions on welding quality based on critical thinking skills. The performance-based assessment provides independence in making decisions. Performance-based assessment is suitable for practical learning that collaborates with motoric movements and knowledge.

Authors: Finn Peter
Published: July 2022

Low-traffic neighbourhoods (LTNs) have become an unexpected political battle ground during the Covid-19 pandemic, becoming interwoven with contestations relating to special powers, democracy, traffic flow, and environmental and climate change related, targets. This article explores the politics surrounding the implementation of LTNs in Ealing as part of the Ealing Council streetspace Programme. In doing, it traces the implementation of nine, and the removal of eight, LTNs, the operation of civil society groups, protest marches, and petitions, inter and intra party political tensions, a High Court submission, and the downfall of the Leader of Ealing Council. Conceptually, it locates events in Ealing within a broader UK polycentric governance environment where policy is navigated within a dynamic environment featuring  central, regional/city, and local state institutions, along with a multi-level judiciary and contested civil society. Didactic in nature, this article teases out learning points of broader applicability related to strategic communication, othering, and stakeholder engagement. It concludes by highlighting that the implementation of LTNs in Ealing should be considered a cautionary tale for those wishing to implement policies with an immediate impact on lived experiences at speed.

Differential expression of MARVEL domain-containing 3 in cancers of the breast.
Authors: Mamoor Shahan
Published: July 2022

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with early-onset breast cancer. We found significant differential expression of the gene encoding MARVEL domain-containing 3, MARVELD3, when comparing primary tumors of the breast to the tissue of origin, the normal breast: in women aged 45 and younger, and women aged 70 and higher. MARVELD3 was also differentially expressed in the brain metastases of patients with brain metastatic breast cancer. MARVELD3 mRNA was present at significantly higher quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of MARVELD3 in primary tumors of the breast was correlated with recurrence-free survival in patients with basal, luminal A and luminal B subtype breast cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. MARVELD3 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Published: July 2022

Kemajuan ilmu pengetahuan, teknologi komunikasi dan informasi serta perkembangan perekonomian dan perdagangan. Menyebabkan Pemerintah dihadapkan pada massa rakyat yang semakin liberal dan individualis yang cenderung menafikkan keberadaan dan keagungan budaya dan agama. Dan semakin kritis dan rasionalnya massa rakyat yang diindikasikan melalui perhitungan atau pertimbangan untung rugi yang diukur secara ekonomis serta pragmatis. Pragmatisme dan sekularisme dalam kehidupan bermasyarakat di satu sisi, di sisi lain tradisionalisme dan religiusitas masih berkembang subur di masyarakat. Pola berpikir pragmatisme dan sekularisme berakibat pada merapuhnya sikap-sikap toleran antar warga negara. Rakyat cenderung mengelompok pada kesamaan kepentingan ekonomi disamping terus mencari perbedaan dan memilah-milah masyarakat yang didasarkan kepada ukuran-ukuran ekonomis. Oleh karena itu pemerintah harus cerdas untuk mampu menghadapi era globalisasi dan revolusi 5.0 dengan penuh keyakinan dan kepercayaan diri, antara lain adalah bahwa tantangan globalisasi dan revolusi digital tidak mungkin dapat dihindarkan dimana batas-batas antar dan negara sudah semakin transparan.

Loneliness
Authors: Cranier Louis
Published: July 2022

Loneliness is an unpleasant emotional response to perceived isolation. Loneliness is also described as social pain—a psychological mechanism which motivates individuals to seek social connections. It is often associated with an unwanted lack of connection and intimacy. Loneliness overlaps and yet is distinct from solitude. Solitude is simply the state of being apart from others; not everyone who experiences solitude feels lonely. As a subjective emotion, loneliness can be felt even when a person is surrounded by other people.
Emotions as Computations
Authors: Emanuel Aviv , Eldar Eran
Published: July 2022

Emotions ubiquitously impact action, learning, and perception, yet their essence and role remain widely debated. Computational accounts of emotion aspire to answer these questions with greater conceptual precision informed by normative principles and neurobiological data. We examine recent progress in this regard and find that emotions may implement three classes of computations, which serve to evaluate states, actions, and uncertain prospects. For each of these, we use the formalism of reinforcement learning to offer a new formulation that better accounts for existing evidence. We then consider how these distinct computations may map onto distinct emotions and moods. Integrating extensive research on the causes and consequences of different emotions suggests a parsimonious one-to-one mapping, according to which emotions are integral to how we evaluate outcomes (pleasure & pain), learn to predict them (happiness & sadness), use them to inform our (frustration & content) and others’ (anger & gratitude) actions, and plan in order to realize (desire & hope) or avoid (fear & anxiety) uncertain outcomes.
Does alleviating poverty increase cognitive performance? Short and long term evidence from a randomized controlled trial

Published: July 2022

In this Registered Report, we investigated the impact of a poverty alleviation program on cognitive performance. We analyzed data from a randomized controlled trial conducted on low-income, high-risk individuals in Liberia where a random half of the participants (n=251) received a $200 lump-sum unconditional cash transfer - equivalent approximately to 300% of their monthly income - while the other half (n= 222) did not. We tested both the short-term (2-5 weeks) and the long-term (12-13 months) impact of the treatment via several executive function measures. The observed effect sizes of cash transfers on cognitive performance (b = 0.13 for the short- and b = 0.08 for the long-term) were roughly four times smaller than suggested by prior non-randomized research. Bayesian analyses revealed that the overall evidence supporting the existence of these effects is inconclusive. A multiverse analysis showed that neither alternative analytical specifications nor alternative processing of the dataset changed the results consistently. However cognitive performance varied between the executive function measures, suggesting that cash transfers may affect the subcomponents of executive function differently.
Question asking fosters curiosity and learning in children

Published: July 2022

Children who are more curious learn more and perform better in school. Although there has been some work on how to induce curiosity in the moment, much less is known about how to promote curiosity-driven behaviors across contexts. In a preregistered experiment, 103 children ages 5-7-years-old participated in eight virtual science lessons over two weeks. Children were randomly assigned to a condition in which they were encouraged to ask questions, or to a condition in which they were asked to listen carefully. At the end of training, children in the question-asking condition valued new science information significantly more than children in the listening condition. They also learned marginally more than children in the listening condition. Children with less background knowledge benefited more from question-asking practice. Our results suggest that question-asking practice can boost some aspects of curiosity and learning.
Understanding spatial, semantic and temporal influences on audiovisual distance compression in virtual environments
Authors: Finnegan Daniel , Petrini Karin , Proulx Michael , O'Neill Eamonn
Published: July 2022

Perception of distance in virtual reality (VR) is compressed; that is, objects and the distance between them and the observer are consistently perceived as closer than intended by the designers of the VR environment. Although well documented, this phenomenon is still not fully understood or defined with respect to the factors influencing such compression. Studies on distance compression typically factor auditory or visual stimuli individually, critically neglecting to study how such stimuli may interact. They also tend to focus on simple static environments involving simple objects that don't move. VR can be -- and at its best should be -- a multisensory experience, involving not only vision but also auditory and potentially other senses. We report a study encompassing 2 experiments exploring spatial, semantic, and temporal factors of congruency in environments -- environments where visual and audio cues do not correlate one-to-one as they would in a physical environment -- on distance compression. Results suggest no impact of semantic association, yet significant effects for temporal and spatial congruence. We discuss the impact of our findings on virtual environment design and implementation.
Empathic and counter-empathic emotions shape social hierarchy based on group positionality
Authors: Hudson Sa-kiera Tiarra Jolynn
Published: July 2022

Hierarchical relations between social groups are influenced by structural and interpersonal forces that reify or dismantle inequality. Here, I review two categories of emotional antecedents to hierarchy maintenance – empathic and counter-empathic emotions – which directly impact the cooperative or competitive nature of intergroup relations. Empathy is the ability to understand and experience the assumed emotional states of other people while counter-empathy is the ability to understand but experience the opposite assumed emotional states of others. Feeling empathy is affiliative, facilitating group cooperation and social interconnectedness. In contrast, counter-empathy is disaffiliative, facilitating social domination and competition. Asymmetric power hierarchies between groups becomes perpetuated when people affiliate and thus experience empathy towards groups that are at the top of the hierarchy, as well as when people disaffiliate and experience counter-empathy towards groups at the bottom. In contrast, hierarchical relationships become attenuated when people affiliate with those at the bottom of the hierarchy or disaffiliate with those at the top. In this way, the hierarchy attenuating or maintaining consequences of empathy and counter-empathy depend on the target groups’ positionality within the hierarchy, suggesting the importance of contextual power dynamics in understanding the implications of social emotions.

Objective: Vaccines are an effective means to reduce the spread of diseases, but they are sometimes met with hesitancy that needs to be understood.Methods: In this study, we analysed data from a large, cross-country survey conducted between June and August 2021 in 43 countries (N = 15,740) to investigate the roles of trust in government and science in shaping vaccine attitudes and willingness to be vaccinated. Results: We found that, despite significant variability between countries, both forms of institutional trust were associated with a higher willingness to receive a COVID-19 vaccine. Further, we found that conspiratorial thinking and anti-expert sentiments predicted reduced trust in government and science, respectively, and that trust mediated the relationship between these beliefs and ultimate vaccine attitudes. Although most countries displayed similar relationships between conspiratorial thinking and anti-expert sentiments, trust, and vaccine attitudes, we identified three countries (Brazil, Honduras, and Russia) with significantly differing effects of these variables. Conclusions: We discuss and propose various additional local factors that future research should consider to understand how trust and attitudes towards governmental and scientific institutions may shape individuals’ ultimate vaccine attitudes and decisions.
Ritualization of Space and Body in Mithila Folk Arts
Authors: Parajuli Bishwo Raj
Published: July 2022

This paper revisits the process of formation and ritualistic differentiation of the space of Kohbar and Aripana patterns traditionally painted on the mud walls of honeymoon chamber and the yards for pujas respectively. Kohbar and Aripana are the most celebrated folk art performances in the Mithila region of Nepal (and also in the Madhuvani District of Northern India). Kohbars are the ritualistic invocation through painted diagrams of kamala daha (seven-lotus pond motif) and several symbols of fertility and auspiciousness that are supposed to invite conjugal happiness and fertility power especially for newly married couple. Kohbars are often associated with Tantrism and procreative intercourse of opposite sex. Similarly, Aripanas are intricately designed decorative patterns performed on the sacred floor or yards especially during pujas and other auspicious occasions. The study of ritualization of space is relevant and important while studying folk art forms like Kohbar, Aripana, Ashtimki, etc. because ordinary spaces like yards, walls and floors are given special significance during such performances. These spots become sacred spaces for drawing some divine patterns and installing paraphernalia for specials rituals or pujas. The study basically incorporates Catherine Bell’s ideas on ‘Ritualization of Spaces’ and ‘Improvisation of Rituals’. The method of the study is based on the close observation of selected Kohbar and Aripana paintings as cultural texts. The critical analysis of the contents and performative details is expected to derive some cogent conclusion. This study attempts to pave the way for further studies on a number of similar folk art forms.
