Negative Emotions and e-Learning Academic Performance of Engineering Students in a Private University

One of the early pandemic COVID-19 effects on the educational sector is that learning activities needto be conducted fully online (e-learning). This circumstance can trigger negative emotions thatcontribute to students’ academic performance. This study aimed to find empirical data regarding therelationship of negative emotions and students academic performance in this particular situation. Thestudy was a cross-sectional quantitative method. Questionnaire of negative emotion (DASS-21)Indonesian version was deployed using google form to students of Industrial Engineering andInformation Systems class of 2020 using convenience sampling. 292 questionnaires were returnedand used. Findings: All three negative emotions (depression, anxiety, and stress) were experiencedby students at different levels. Negative emotions had different correlations to academic performance.There were no significant differences between anxiety and depression to students’ academicperformance (anxiety: F (3) = 2.202, ρ = 0.088, depression: F (2) = 1.397, ρ = 0.249). Two-wayANOVA showed that students who experienced mild stress performed better than those with normalstress category (F (1) = 3.933, ρ = 0.048). Female students significantly had better academicperformance compared to male students (ρ (0.001) < α= 0.05)) and that students experienced mildstress, performed better than those with normal stress category. Managing stress at a moderate levelis beneficial and can be done by media or counseling or other catharsis methods. Further study usinglarger samples from non engineering majors and randomized sampling is needed for generalizationas well as identifying factors that contribute to e-learning performance in a special situation.

Evaluating the role of binge planning and binge inevitability within affect regulation models of binge eating

Affect regulation models posit that aversive affective states drive binge-eating behavior, which then regulates negative emotions. However, recent findings among individuals with binge-eating disorder (BED) suggest that food-related anticipatory processes may precede and potentially explain the negative affect thought to drive binge eating. Specifically, studies using ecological momentary assessment (EMA) demonstrate that the negative affective state of “Guilt” (from the Positive and Negative Affect Schedule) most strongly predicts later binge eating in the natural environment, and it has been hypothesized that planning a binge or feeling that a binge-eating episode is inventible may account for the increases in Guilt observed prior to binge episodes. In the present study, we tested the hypothesis that binge planning or inevitability may contribute to feelings of shame (a key facet of the broader Guilt construct), which then predict binge-eating episodes, using EMA in 43 individuals with BED. Consistent with hypotheses, feelings of binge inevitability and planning prospectively predicted binge-eating episodes. Further, binge planning predicted subsequent increases in shame. However, shame did not predict subsequent increases in binge planning. Finally, a mediation model revealed that binge planning (Time 1) predicted future binge eating (Time 3) directly and indirectly through increases in shame (Time 2). The results provide novel evidence that individuals with BED anticipate and actively plan for binge-eating episodes, and that binge planning may explain the increased shame/guilt typically observed before binge eating. Overall, accruing evidence suggests that negative affect, although predictive of binge eating, may be better conceptualized as a consequence of the anticipatory processes that lead to binge eating, rather than the starting point, at least among some individuals with BED. Future experimental research is needed to more conclusively test this hypothesis.

THE ROLE OF EMOTIONS IN CONSUMER DECISION-MAKING: ANALYZE HOW EMOTIONAL APPEAL IN MARKETING AFFECTS CONSUMER BEHAVIOR

Emotions play a pivotal role in consumer decision-making, influencing how individuals perceive, evaluate, and choose products or services. Emotional appeal in marketing taps into consumers' feelings, often bypassing rational thought to create strong associations with a brand or product. This paper analyzes how emotional appeal shapes consumer behavior by building brand loyalty, enhancing engagement, and driving impulse purchases. Positive emotions such as happiness, excitement, and belonging can foster long-term consumer relationships, while negative emotions like fear or anxiety can prompt immediate action. Through emotional resonance, brands not only differentiate themselves in a crowded marketplace but also create memorable experiences that impact purchasing decisions. The findings suggest that successful emotional marketing strategies are those that align with consumers’ values, desires, and emotional states, highlighting the importance of understanding both rational and emotional drivers in shaping consumer behavior.

Stress in social and health care professionals working with people with intellectual disabilities: risk and protective factors

Objectives Those working in the field of intellectual disabilities are confronted with a multitude of stressors, which can give rise to considerable psychological difficulties. The objective of this study was to identify the key predictors of perceived and relational stress among professionals working in intellectual disability centers. Methods A cross-sectional design was employed, with 726 professionals participating (mean age = 43.35 years, SD = 11.19), predominantly women (78.6%). The variables assessed included perceived stress, relational stress, emotional balance, life satisfaction, social support, empathy, and counseling training. The analysis was conducted using structural equation modeling and qualitative-comparative analysis of fuzzy data (QCA). Results The study revealed that the stress levels of the study participants were moderate to low. The relationship between emotional balance and stress was mediated by life satisfaction. In both structural equation models, negative affect and life satisfaction were identified as primary predictors, significantly influencing perceived and relational stress. Additionally, QCA highlighted that empathy and social support, along with these factors, contribute to explaining stress levels. Conclusions Our findings highlight the necessity of implementing preventive strategies and support systems to mitigate stress among healthcare professionals who work with individuals with intellectual disabilities. These findings contribute to the existing body of knowledge regarding stress management in this specialized healthcare context.

The moderating role of government heuristics in public preferences for redistribution

A theory of rational attitude formation suggests public perceptions that income differences are too large should lead to demands for income redistribution. Public opinion scientists irregularly observe this at best. It is possible that the instruments we use to observe support for income redistribution are ineffective. We suggest at least part of the inconsistently observed linkages are due to unobserved confounding of government heuristics. We hypothesize that government affect provides a heuristic cue for survey respondents to answer questions on their preference for the government engaging in income redistribution. The greater the valence or quantity of reasons for a survey respondent to have negative government affect, the more perceptions of inequality and support for redistribution are decoupled and apparently inconsistent. To test this, we measured government affect at the country-time level using trust, corruption perceptions, and economic performance. We executed tests of moderation using slopes-as-outcomes regressions with ISSP data from 36 countries in 102 country-time points. Given the difficulty in fitting complex theories of society and politics into a limited number of macro-comparative cases, we ran a multiverse analysis of alternatively plausible models. There is a consistent negative moderation effect across models suggesting that our theory of government affect as opinion expression on a survey is worthy of further consideration. The findings also suggest more qualitative cognitive survey interviews to better understand this process.

Anxiety, inhibitory control, physical activity, and internet addiction in Chinese adolescents: a moderated mediation model

BackgroundAdolescents may have anxiety due to a series of events such as school work and social interaction. Improper handling of anxiety often leads to some negative consequences, such as Internet addiction. Therefore, this study further explored the relationship between anxiety and Internet addiction, as well as the mediating role of inhibitory control between the two, and also considered the moderating role of physical activity between anxiety and inhibitory control.MethodsA total of 1607 adolescents, comprising 664 boys and 943 girls with an average age of 15.86 years (SD = 0.73), from Shandong, Shanxi, Hebei, and Hunan provinces completed a self-report survey on physical activity, anxiety, inhibitory control, and Internet addiction. Descriptive analysis, correlation analysis, and mediation test were conducted.ResultsThe results revealed a significant positive correlation between anxiety and adolescent internet addiction (r = 0.413, p < 0.001), and a significant negative correlation with inhibitory control (r = -0.423, p < 0.001). Inhibitory control was found to be significantly positively correlated with physical exercise (r = 0.143, p < 0.001) and significantly negatively correlated with internet addiction (r = -0.368, p < 0.001). After controlling for demographic variables, anxiety significantly positively predicted Internet addiction (β = 0.311, p < 0.001) in adolescents, and it also indirectly predicted Internet addiction through inhibitory control (β = -0.231, p < 0.001). Physical activity significantly weakened the predictive effect of anxiety on inhibitory control (β = -0.092, p < 0.001).ConclusionsThis study further explored the issue of psychological mechanisms between anxiety and Internet addiction in adolescents, and added that physical activity alleviates the negative effects of anxiety on adolescents. Schools and families are encouraged to promote physical exercise among adolescents to alleviate the influence of negative emotions on their psychological and behavioral health.

The impact of explaining vegetarian meal requests on the affective responses and perceptions of meat eaters

Social situations can present challenges for those looking to reduce or avoid eating meat. In an experimental vignette study with a large representative sample of 1,117 UK-based meat eaters, we explore affective responses to requests for vegetarian meals and perceptions of those making the request across four social situations: a BBQ, a pub, a restaurant dinner, and a dinner party. We examine moderators of these perceptions including whether the requester presents themselves as vegetarian or a meat restrictor and whether they cite health, environmental or no motives for their request. Overall, we find that these moderators have a greater impact on meat eaters’ perceptions of the requester than on their affective responses to the request. We also find that these outcomes are more impacted by the mention of motives than they are diet type. Standout findings include evidence that people citing environmental motives for their vegetarian meal request are perceived more negatively, while those with health motives are perceived more positively. We also identify substantial heterogeneity across the respondents’ levels of meat attachment: those who are more attached to meat have more negative perceptions of vegetarian meal requesters and experience higher negative affect and lower positive affect in response to the request.

Is the Treatment Worse than the Disease?: Key Stakeholders’ Views about the Use of Psychiatric Electroceutical Interventions for Treatment-Resistant Depression

Psychiatric electroceutical interventions (PEIs) use electrical or magnetic stimulation to treat psychiatric conditions. For depression therapy, PEIs include both approved treatment modalities, such as electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS), and experimental neurotechnologies, such as deep brain stimulation (DBS) and adaptive brain implants (ABIs). We present results from a survey-based experiment in which members of four relevant stakeholder groups (psychiatrists, patients with depression, caregivers of adults with depression, and the general public) assessed whether treatment with one of four PEIs (ECT, rTMS, DBS, or ABIs) was better or worse than living with treatment-resistant depression (TRD) and then provided a narrative explanation for their assessment. Overall, the prevalence of many narrative themes differed substantially by stakeholder group—with psychiatrists typically offering different reasons for their assessment than non-clinicians—but much less so by PEI modality. A large majority of all participants viewed their assigned PEI as better than living with TRD, with their reasons being a mix of positive views about the treatment and negative views about TRD. The minority of all participants who viewed their assigned PEI as worse than living with TRD tended to express negative affect toward it as well as emphasize its riskiness, negative side effects, and, to a lesser extent, its invasiveness. The richness of these narrative explanations enabled us to put in context and add depth to key patterns seen in recent survey-based research on PEIs.

국어교사의 음성에 대한 고등학생들의 선호도 및 감정 반응 조사 연구

Objectives The purpose of this study is to investigate the characteristics of the voice of Korean language teachers preferred by students by examining the preferences and emotional responses of high school students to the voice of Korean teachers. Methods To this end, after producing a test tool consisting of a questionnaire and 12 audio data of Korean teachers, 514 high school students were selected as subjects for the study to investigate the preference and emotional response. Results First, high school students tended to prefer voices that make them focus on classes, accurately convey the contents of the class, and prevent them from getting sleepy. Second, It was found that high school students' preference for the voice of Korean teachers was moderate. Third, there was no significant difference in students' preferences according to the presence or absence of voice problem of Korean teachers, but there was a significant difference in preference according to gender and career. Fourth, it was found that abnormal voices evoke more negative emotions in students than normal. Fifth, it was found that there was a positive correlation between the positive emotions and preferences of Korean teachers, and a negative correlation between negative emotions and preferences. Conclusions Korean teachers need to check and manage their voice usage patterns in order to enhance students' task performance and concentration, and in particular, they need to adjust their voice so that they can elicit a positive response from students so that they do not get bored. In addition, when a Korean teacher controls the voice in class, the situation of the class, such as the number of students and the structure of the classroom, should be considered. Finally, in order to create voice education materials for Korean teachers, it is necessary to analyze the voice usage patterns of highly experienced teachers.

Pathological personality dimensions and neurobiological emotional reactivity.

The Hierarchical Taxonomy of Psychopathology (HiTOP) offers a promising framework to identify the neurobiological mechanisms of psychopathology. Many forms of psychopathology are characterized by dysfunctional emotional reactivity. The late positive potential (LPP) is an event-related potential component that provides an index of neurobiological emotional reactivity. Several categorical disorders have demonstrated a similar association with the emotion-modulated LPP. It is possible that higher-order dimensional representations of psychopathology might explain the comparable results. The present study examined the association between HiTOP-consistent pathological personality dimensions across multiple levels of the hierarchy and neurobiological emotional reactivity. The sample included 215 18-35-year-old adults (86% female) who were oversampled for psychopathology. Participants completed the emotional interrupt task while electroencephalography was recorded to examine the LPP. Participants also completed the Comprehensive Assessment of Traits relevant to Personality Disorders to assess pathological personality. At the spectra level, higher negative emotionality was associated with a larger emotion-modulated LPP, while higher detachment was associated with a smaller emotion-modulated LPP. There were no associations between higher-order psychopathology levels and the emotion-modulated LPP. Compared to categorical diagnoses, spectra-level personality pathology dimensions significantly improved the prediction of the emotion-modulated LPP. The present study indicates that HiTOP spectra levels of negative emotionality and detachment demonstrate unique associations with neurobiological emotional reactivity. The study highlights the utility of examining dimensional and hierarchical, rather than categorical, representations of psychopathology in the attempt to identify the neurobiological origins of psychopathology.

Anxiety-Related Emotions of University Students When Using English as a Foreign Language in Class: Comparing Health and Educational Sciences

&lt;p style="text-align:justify"&gt;In the realm of education, particularly in the domain of second language acquisition, understanding the intricate interplay between emotions and learning processes is a challenging endeavor. This research aims to explore the importance of studying anxiety-related emotions in the learning and teaching of English as a foreign language by conducting a study based on a quantitative methodology. To that end, a 33-item instrument was given to a total of 231 (n=231) university students who learn and use English in class in diverse degrees in the social and health sciences. The results obtained shed light on the negative emotions that students report during their English classes, such as fear, shame, nervousness, or feelings of judgement. However, not all the emotions are negative, since students also feel relaxed and interested. This study offers a new perspective on this topic since it compares different disciplines, underscoring the need to detect trends in different areas and therefore tailor pedagogy to different student profiles and degree programs.&lt;/p&gt;

Unveiling public perceptions at the beginning of lockdown: an application of structural topic modeling and sentiment analysis in the UK and India

BackgroundThe appearance of the COVID-19 virus in December 2019, quickly escalated into a global crisis, prompting the World Health Organization to recommend regional lockdowns. While effective in curbing the virus’s spread, these measures have triggered intense debates on social media platforms, exposing widespread public anxiety and skepticism. The spread of fake news further fueled public unrest and negative emotions, potentially undermining the effectiveness of anti-COVID-19 policies. Exploring the narratives surrounding COVID-19 on social media immediately following the lockdown announcements presents an intriguing research avenue. The purpose of this study is to examine social media discourse to identify the topics discussed and, more importantly, to analyze differences in the focus and emotions expressed by the public in two countries (the UK and India). This is done with an analysis of a big corpus of tweets.MethodsThe datasets comprised of COVID-19-related tweets in English, published between March 29th and April 11th 2020 from residents in the UK and India. Methods employed in the analysis include identification of latent topics and themes, assessment of the popularity of tweets on topic distributions, examination of the overall sentiment, and investigation of sentiment in specific topics and themes.ResultsSafety measures, government responses and cooperative supports are common themes in the UK and India. Personal experiences and cooperations are top discussion for both countries. The impact on specific groups is given the least emphasis in the UK, whereas India places the least focus on discussions related to social media and news reports. Supports, discussion about the UK PM Boris Johnson and appreciation are strong topics among British popular tweets, whereas confirmed cases are discussed most among Indian popular tweets. Unpopular tweets in both countries pay the most attention to issues regarding lockdown. According to overall sentiment, positive attitudes are dominated in the UK whilst the sentiment is more neutral in India. Trust and anticipation are the most prevalent emotions in both countries. In particular, the British population felt positive about community support and volunteering, personal experiences, and government responses, while Indian people felt positive about cooperation, government responses, and coping strategies. Public health situations raise negative sentiment both in the UK and India.ConclusionsThe study emphasizes the role of cultural values in crisis communication and public health policy. Individualistic societies prioritize personal freedom, requiring a balance between individual liberty and public health measures. Collectivistic societies focus on community impact, suggesting policies that could utilize community networks for public health compliance. Social media shapes public discourse during pandemics, with popular and unpopular tweets reflecting and reshaping discussions. The presence of fake news may distort topics of high public interest, necessitating authenticity confirmation by official bloggers. Understanding public concerns and popular content on social media can help authorities tailor crisis communication to improve public engagement and health measure compliance.

Unmasking the Pandemic's Dark Side: Exploring the Roles of Stress, Emotions, and Alcohol Use in Violent Behavior Across Six Countries.

We use international survey data recently collected among adults in six countries (Ukraine, Guatemala, Pakistan, the Netherlands, Denmark, and the United States) to examine the global variations in interpersonal violent behavior during the COVID-19 pandemic. We find that pandemic-related stress is significantly associated with violent behavior in most countries. Depression emerges as a significant predictor of violence across all countries and as a mediator between pandemic stress and violent behavior in multipls contexts. On the other hand, negative affect and alcohol use predict violent behavior only in non-Western contexts. We provide policy implications focused on prevention and reduction of violence cross-nationally during public health crises.

Intervention to Improve Well-Being, Nutrition, and Physical Activity in Adults: Experimental Study.

Mindfulness improves well-being, improves emotional regulation, reduces impulses to eat, and is linked to increased physical activity. Mindfulness interventions usually focus on 1 aspect but do not offer an approach to holistically improving lifestyle. This study aims to address this gap by designing and evaluating a holistic mindfulness intervention. Committing to a 12-week intervention with 2-hour sessions without knowing whether you will enjoy it can be a hindrance for someone completely unfamiliar with mindfulness. For this reason, we decided to design a mindfulness intervention with short sessions over a reduced number of weeks. The aim is to enable novices to discover different aspects of mindfulness while at the same time offering a satisfactory practice for people who are already practicing mindfulness. We designed and evaluated a web-based mindfulness intervention in 5 sessions of 5 to 10 minutes each on well-being, diet, and physical activity to support a healthier lifestyle. The first 2 sessions focus on formal mindfulness meditation to enable novices to discover mindfulness and its main principles. Then there are 2 sessions about food. The first session about food aims to develop a sense of satisfaction with the food we eat and to focus our attention on new sensations. The second session about food aims to develop the ability to resist the lure of unhealthy foods. Finally, there is a session on physical activity. The aim is to develop a particular awareness of the body during movement, to increase satisfaction with physical activity, and to develop regular exercise. In total, 32 participants completed the intervention. After the intervention, we observed decreases in negative affect, anxiety, and emotional distress, and an increase in dispositional mindfulness. There was no effect on reported healthy eating habits and physical activity habits. Few participants repeated the exercises as recommended. The majority of our participants were new to mindfulness. The majority of our participants reported being satisfied with the different sessions. A few minor difficulties were mentioned, mainly related to the environment in which the participants carried out the sessions. Only 1 session was less satisfactory for one-third of the participants. The session on resistance to unhealthy foods was formulated too strictly and the idea of banning certain foods was a hindrance for one-third of the participants. A reformulation is needed. The mindfulness exercises were well accepted and promoted a state of mindfulness. It would be interesting to provide easier technical access to the exercises via a mobile app so that they can be repeated easily.

Too much work frustrates me! A mediation model of career-related outcomes of work overload

PurposeWork overload implies that there are excessive work demands that cannot be adequately fulfilled within the given deadlines. This research examines the effect of work overload on career outcomes, i.e. career satisfaction and occupational commitment through the mediating role of work frustration.Design/methodology/approachThe data were collected from employees working in the schools of Punjab, Pakistan in three waves. Out of the total, 248 valid responses were analyzed by PROCESS model 4 using SPSS 24.FindingsBased on affective event theory (AET) the results demonstrated that negative workplace events such as work overload create negative emotions like frustration at work and cause poor job outcomes (i.e. low satisfaction and commitment).Research limitations/implicationsHowever, the outcomes should be interpreted in the light of single sector and time-lagged data tested on the mediation-only model.Practical implicationsThe current study has implications for workload management in school staff to retain their career satisfaction and commitment.Social implicationsThis study has implications for society by offering to enhance the career outcomes of school staff that are prime institutions for socio-economic development.Originality/valueThis is one of the initial research studies that have examined the career-related outcomes of work overload based on AET via the mediating role of work frustration.

Revealing the distinct impacts of effectiveness recognition and memory retention on the transfer of creative cognitive reappraisal

ABSTRACT Previous research has shown that creative cognitive reappraisal is highly effective in regulating negative emotions. We conducted three experiments to explore its transferability. In Experiment 1, we observed that free recall performance was better for creative reappraisal compared to non-creative reappraisal. Memory retention of reappraisals was associated with creativity ratings, but not with perceived effectiveness ratings. In Experiment 2, participants generated reappraisals for newly introduced unpleasant images before (pre-session) and after (post-session) exposure to creative reappraisal, non-creative reappraisal, and descriptive control interpretation. Results showed increased reflective effectiveness of self-generated reappraisals in the post-session. The level of creativity of the self-generated reappraisals was associated with differences in perceived effectiveness between creative and non-creative exposed reappraisals. In Experiment 3, we investigated how two processing approaches (effectiveness-oriented vs. memory-oriented) influenced the transferability of creative reappraisal. We observed creativity levels of self-generated reappraisals increased in both conditions. The reflective effectiveness of the self-generated reappraisals tended to increase only in the effectiveness-oriented processing condition. Our findings demonstrate that recognising the effectiveness of creative reappraisal plays a crucial role in its transfer across different situations.

Methodological Variations to Explore Conflicting Results in the Existing Literature of Masking Smile Judgment.

Although a smile can serve as an expression of genuine happiness, it can also be generated to conceal negative emotions. The traces of negative emotion present in these types of smiles can produce micro-expressions, subtle movements of the facial muscles manifested in the upper or lower half of the face. Studies examining the judgment of smiles masking negative emotions have mostly employed dichotomous rating measures, while also assuming that dichotomous categorization of a smile as happy or not is synonymous with judgments of the smile's authenticity. The aim of the two studies was to explore the judgment of enjoyment and masking smiles using unipolar and bipolar continuous rating measures and examine differences in the judgment when instruction varied between judgments of happiness and authenticity. In Experiment 1, participants rated smiles on 7-point scales on perceived happiness and authenticity. In Experiment 2, participants rated the smiles on bipolar 7-point scales between happiness and a negative emotion label. In both studies, similar patterns were observed: faces with traces of fear were rated significantly less happy/authentic and those with traces of anger in the brows were rated significantly happier/more authentic. Regarding varied instruction type, no effect was found for the two instruction types, indicating that participants perceive and judge enjoyment and masking smiles similarly according to these two instructions. Additionally, the use of bipolar scales with dimensions between a negative emotion label and happiness were not consistently effective in influencing the judgement of the masking smile.

Adaptive coping, emotions, and antiretroviral therapy adherence among gay, bisexual, and other men who have sex with men (gbMSM) with HIV.

This study evaluated the hypothesis that positive emotions attenuate associations between negative emotions with adaptive coping and adherence, as well as explored evidence of the hypothesis of an indirect effect association between adaptive coping and adherence via positive emotions. The sample was 202 gbMSM with HIV who use substances (mean age [standard deviation] = 47.15 [12.26]; 34% Black, 14% Hispanic, and ≥50% with annual income ≤$20,000). Positive emotions were a moderator: negative emotions were not associated with approach coping at low positive emotions but were associated with more adaptive coping at high positive emotions (b = 0.32, p = 0.01). There was also an indirect effect association between adaptive coping with better adherence via high positive emotions (indirect effect: 0.29, 95% Confidence Interval = 0.004-0.39). Findings support the likely benefit of experiencing positive emotions, and investment in intensive longitudinal studies on how emotions, coping, and health behaviors are related to inform behavioral intervention development.

Effect of Social Isolation on Behavioural Response of Murrah Buffalo Calves Towards Novelty

Background: During the production cycle, dairy animals in intensive production systems are exposed to various challenging events including novel stimuli (e.g., handlers, food and group-mates). The welfare of an individual animal depends on the ability to cope with environmental challenges. Novelty is generally associated with negative emotions however; individual behavioural and physiological responses toward challenging events can be very variable. So, studying behavioural response of calves towards novelty can help us address the welfare needs of the buffalo calves in a holistic manner. Methods: For this study, 24 Murrah buffalo calves were selected at birth and randomly allotted to four groups (six calves each) comprising of SG group (restricted suckling and group housed), SI group (restricted suckling and individually housed), WG group (weaned at birth and group housed) and WI group (weaned at birth and individually housed) for a period of three months. All calves were trained with bottle feeding from day old of age. At 9th week of age, the behavioural response of the calves to novelty was tested in two different novel situations i.e. novel object test and social novelty test using CCTV camera. Result: The results suggest that buffalo calves separated from mother and housed individually showed increased behavioural responses characterized by increased time in decision making, higher standing idle time and more fearful to an unfamiliar calf compared to other groups. It can be concluded that social isolation of the buffalo calves increases fearfulness to novelty hence reducing their welfare in future.

Sentiment Analysis of Arabic Tweets: Detecting Revilement

Social media systems play an necessary function in shaping public opinion and reflecting societal sentiments. This study focuses on sentiment analysis in Arabic tweets with a particular focus on offensive or offensive content. The aim of this research is to boost a dependable sentiment evaluation model that can accurately classify Arabic tweets as positive or negative, with a particular focus on identifying offensive language. A multinomial Naive Bayes classifier is trained on pre-processed data to perform sentiment classification. The classifier is fine-tuned to differentiate between positive and negative emotions, with a particular focus on identifying offensive or swearing language. The model is evaluated the usage of a complete set of metrics along with precision, precision, recall, and F1score. Experimental consequences point out promising overall performance of the developed sentiment evaluation model. The model achieved an accuracy of 93%, effectively classifying Arabic tweets into effective and bad sentiments. The precision, recall, and F1-score metrics similarly validate the model's capacity to precisely become aware of revilement and offensive language. These outcomes spotlight the conceivable of the proposed strategy in successfully examining Arabic tweets for sentiment and offensive content, contributing to higher grasp on line behaviors and sentiments in the context of revilement.
