IoT Technology in Urban Waste Management: Smart Waste Bin Systems
Authors: Guo Jinjing
Published: February 2025

With the acceleration of urbanization, municipal waste management has become a critical research topic. Concurrently, the Internet of Things (IoT) is rapidly evolving, closely paralleling the urbanization process. Many researchers have attempted to integrate IoT into municipal waste management, achieving notable results. However, there remains a significant gap in the development of smart waste bins, which serve as the nerve endings of IoT waste management systems. This paper proposes a smart waste bin design concept based on the STM32 microcontroller for real-time monitoring and management of urban waste, exploring the application of IoT in this domain. The smart waste bin integrates sensors, control systems, and Internet technologies to facilitate remote monitoring and automated control. Through real-time monitoring with components such as infrared sensors and MQ2 sensors, the system collects essential waste bin parameters. These parameters are then transmitted to the network using a GSM module. Simultaneously, users can remotely monitor and control the smart waste bin via a mobile application, allowing them to check the bin's capacity, receive alarm notifications, and remotely manage the bin's status. This design significantly enhances the efficiency of waste bin management in cities with decentralized locations, offering a convenient and intelligent solution for urban waste management and IoT applications. Despite these advancements, there is considerable room for improvement in the interaction capabilities of smart bins with IoT systems, users, and managers, as well as in their design and cost-efficiency.
Measuring Exhaled Carbon Monoxide Can Rapidly Increase Confidence to Quit Cigarette Smoking
Authors:   Department of Medicine, Oldendorf Medical Services, Loudonville, NY, USA, Lee Hwal
Published: February 2025

Background: Confidence to quit cigarette smoking has been shown to predict quit attempts and abstinence regardless of level of motivation, but limited evidence exists on enhancing smokers’ confidence level

Objective: This study assessed the impact of exhaled carbon monoxide (eCO) measurement on adult cigarette smokers’ confidence and motivation to quit (n = 22) and explored predictors of confidence and motivation.

Methods: Level of confidence and motivation was measured verbally using a 0-10 scale immediately before and after eCO measurement, and smoking history information was collected using a written survey.

Results: Post-eCO confidence level was significantly higher vs pre-eCO (7.09 vs 5.55, 27.7% increase; p = 0.004, d = 0.50), and non-significant post-eCO increase in motivation was found (8.41 vs 7.64, 10.1% increase; p = 0.070, d = 0.31). Baseline confidence level had a significant moderately negative association with pack-year smoking history, and baseline motivation level had a significant strongly negative association with pack-year smoking history, current average number of cigarettes smoked per day, and baseline eCO value.

Conclusion: In the current study, measuring eCO intrinsically led to a significant increase in adult cigarette smokers’ confidence to quit and a non-significant increase in their motivation to quit. Thus, measuring eCO may help facilitate quit attempts and abstinence in community-dwelling adult cigarette smokers by rapidly increasing their confidence to quit.

Phonetic Approximation in Bilingual Pun and Their Impact on Response Times for Young Chinese-English Bilinguals
Authors: Chen Jiaqing , Wang Daniel , Zhang Yichi
Published: February 2025

This study, integrating psycholinguistic and sociolinguistic perspectives, investigates bilingual puns with phonetic approximations between two languages, Chinese and English, as a medium for humour and identity expression, and how phonetic approximations involving consonantal shifts (e.g., s/sh and f/h), vowel transformations, rhoticity, and additional schwa influence participants perception of bilingual pun stickers. A quantitative approach was used, involving two experiments: a speech production and perception task, and a response-time experiment. These assessed participants responses to phonetic approximations in controlled experiments and real-world pun stickers. The results indicate that phonetic similarity, particularly in consonants, leads to faster recognition times, while more pronounced differences, such as between /f/ and /h/, hinder recognition. Vowel roundness, diphthong shifts, and hiatuses were also found to significantly affect pun comprehension, whereas schwa insertion and rhoticity were less influential. The findings highlight the importance of phonetic awareness in bilingual education, with a focus on vowel and consonant accuracy in speech perception and production, and suggest applications of bilingual pun stickers in second language teaching, while acknowledging limitations such as sample size and the absence of multimodal analysis.
Causal Role for Visual Cortex in Processing Visual Semantics
Authors: Xie Kei , Zhang Bert
Published: February 2025

This article reviewed previous studies testing for the causal or correlational relationship between modality-specific brain regions (e.g. motor cortex) and processing of corresponding perceptual-motor semantics. The proposed experiment aimed to investigate the functional role of visual cortex in understanding visual-associated words by studying the selective effect of transcranial direct current stimulation (tDCS) to primary visual cortex on response time (RT) to visual-associated words in lexical decision task. Participants will receive either sham or true anodal-tDCS, then perform the auditory lexical decision task to decide if the stimulus is a word in English or a pseudoword word. The experimental prediction was that compared to sham tDCS, anodal tDCS will affect the RTs with visual-associated word stimuli significantly more than to nonvisual-associated word stimuli. If the experimental prediction is supported, then this experiment would provide additional empirical evidence for the embodied simulation hypothesis, whilst establishing a causal role for visual cortex in visual semantic processing.
Risk Decision and Social Comparison in Gambling among Non-gamblers and Gambling Disorder Patients
Authors: Wang Zushen , Mao Sebastian , Li Xuanyu , Hu Ruofan
Published: February 2025

Previous studies have supported the view that gambling disorder is associated with impaired decision-making. While scholars try to explain it through neurobiological approaches, this study aims to investigate different explanations from the perspective of evolutionary psychology. Our research will mainly focus on the underlying malfunction of risk sensitivity mechanism and effect of social comparison. Participants consist of non-disordered people and gambling disorder patients selected from volunteers and patients from hospital. There are two different situations (visible and invisible) to identify the impact of social comparison. Participants are supposed to choose different risk levels to get higher scores. The expected result of this experiment will be under the combined influence of the mechanism malfunction and social comparison. For gambling disorder patients, the malfunction of risk sensitivity mechanism will lead to an extreme preference for high risk and scores, while non-gamblers will stop or choose a low risk level after obtaining enough or a high score. Affected by social comparison, both kinds of participants will manifest a tendency for higher risk. This study will contribute to explaining differential performance between individuals with gambling disorders and non-gamblers in the gambling scenario through the theory of evolutionary psychology.

Authors: Yang Yichen Garith
Published: February 2025

This essay examines the 2024 animal documentary Queens through a feminist lens. Against the backdrop of traditional storytelling dominated by androcentric perspectives, feminist scholars have long advocated for the creation of female-centered narratives to reclaim agency and challenge gendered norms. As both an educational and artistic work, Queens contributes to the practice of gynocentric storytelling in contemporary media. By showcasing matriarchal societies across various animal species, the documentary provides a narrative centered on female perspectives. This essay analyzes how the stories in Queens celebrate the power and qualities of femininity through the portrayal of anthropomorphic animal characters and female animal workers in real life. It also compares the narration of Queens with that of other wildlife documentaries and examines the Chinese translation to illustrate how language constructs female subjectivity. Finally, the essay identifies unresolved issues and controversies within the documentary and proposes directions for future feminist creators to advance matriarchal narratives further.

Published: February 2025

Process drama has been widely utilized in educational settings to enhance student engagement and achieve communicative goals. Despite its growing application, there is limited empirical evidence assessing its effectiveness specifically for improving English as a Foreign Language (EFL) speaking competence among undergraduate students in China. This study investigates the efficacy of process drama in enhancing EFL speaking competence among non-English major undergraduates in China. A total of 84 participants were involved, with 42 assigned to an experimental group (EG) that received process drama-based instruction, and 42 to a control group (CG) that followed conventional teaching methods. Data were collected through pre- and post-tests evaluating speaking competence. The analysis employed paired samples t-tests, independent t-tests, and ANCOVA to compare the pre- and post-test results. The results demonstrated significant improvements in speaking competence in both groups; however, ANCOVA revealed that the EG exhibited significantly greater improvement compared to the CG (p = .003). This study confirms that process drama is significantly more effective than conventional teaching methods in enhancing English speaking competence, providing novel insights into the specific benefits of process drama, highlighting its potential to address the limitations of traditional teaching approaches and offering a valuable contribution to the field.

Authors: Ahmad Farhan , Shams Anam , Amin Khalid , Alam Sohaib , Khalid Sadaf , Haque Shafey Anwarul , Warda Wahaj Unnisa
Published: February 2025

There is a growing concern that disinformation, particularly transmitted through mobile phones, television, and social media, is fuelling social tension and even violence at times. Ample evidence, along with anecdotal interpretations, is available to illustrate how digital and mainstream media platforms in India have turned into pernicious channels for spreading hatred and violence. The proposed study investigates how propaganda, disinformation and fake news are used as polarization tools to elevate a particular political ideology or practice in a democracy like India. The study highlights a series of events and hashtags used on X (earlier Twitter) and other social platforms using derogatory language or agendas against communities and people of dissent. The media is wielded as a tool to spread polarized discourses that serve the interest of the ruling dispensation. Using some examples of fake news and propaganda, this paper draws attention to media propaganda and its effects on minorities, Muslims in particular, and human intellect in general. The research looks at how political goals shape propaganda definitions and signs, symbols, or languages used against minorities, who are largely portrayed as ‘others’ in the country. Additionally, it delves into the strategies and techniques employed by prejudiced media to shape reality, as well as how they undermine cultural norms and promote divisive policies of the ruling regime. The investigation of specific texts, videos, and audios will support the study. The findings reveal that such propagandised media or sources of information can have both positive and negative effects on the democratic process. The study uses some cases as examples to show how disinformation or media manipulation restricts the freedom of expression, food habits, mobility, and affiliation of the country's minorities. This is troubling because stigma can lead to more hostile attitudes toward integration or weaken one's sense of belonging in democracies.

O acesso de transexuais e travestis à educação superior na perspectiva da democratização
Authors: Lima Tatiane , Elisabeth Maciel Carina
Published: February 2025

Este artigo tem como objetivo discutir a democratização do acesso considerando como transexuais e travestis se inserem nesse contexto, explorando, sobretudo, a promulgação de políticas para educação superior durante os governos de Luiz Inácio Lula da Silva (2003 - 2010) e de Dilma Rousseff (2011 - 2016). Para tanto, foi desenvolvido por meio de pesquisa documental e bibliográfica, tendo como fontes produções acadêmicas, notícias em mídias sociais, políticas, documentos orientadores como os relatórios do Banco Mundial (BM), planos, programas e atos normativos, como portarias, resoluções, normativas, dentre outros documentos que fazem menção às pessoas transexuais e travestis no âmbito educacional. Como resultado, evidencia-se que, embora a democratização do acesso mediante as políticas de educação superior também propicie o ingresso de transexuais e travestis, ainda não são suficientes para abranger suas especificidades. Nesse contexto, as estratégias engendradas pelo Estado, pelos movimentos sociais e pelas universidades públicas, como as regulamentações de nome social, a visibilidade positiva, os cursinhos trans, as cotas nas universidades e as pesquisas quantitativas, viabilizam a integração das reivindicações consequentes das injustiças culturais e econômicas que interferem nesse processo.
