Unmasking Fake Opinions through Behavioral Analysis and Machine Learning: Identifying Genuine Users vs. Fraudulent Actors
Authors: S. Ulle Ravishankar , Yogananthan S.
Published: January 2025

The proliferation of fake online opinions undermines consumer trust and distorts decision-making processes. Traditional detection methods relying on content analysis face limitations, such as difficulty in identifying sophisticated fraudulent behavior and adapting to new patterns. This paper investigates the potential of combining behavioral analysis with machine learning (ML) to improve the detection of fake reviews. Through a comprehensive review of existing literature, we explore behavioral analysis techniques for identifying suspicious activities and the application of ML algorithms for automated detection. We propose a conceptual framework focusing on reviewer behavior, review content, and review authenticity as primary variables while considering platform characteristics and product categories as moderating factors and reviewer motivation as a mediating factor. The integration of these dimensions aims to capture the nuances of fraudulent activities and enhance detection accuracy. By identifying key research gaps, such as the lack of real-time detection methods and insufficient focus on behavioral indicators, this review formulates targeted research questions to guide future studies. Our findings suggest that the synergy between behavioral analysis and ML holds promise for developing robust systems to unmask fake online opinions. This research contributes to advancing detection methods and restoring consumer trust in online platforms.

Published: January 2025

For some visitors, natural tourism represents an attractive form of tourism in itself. One of the most notable natural attractions in North Sumatra is Ergendang Cave, situated in Penungkiren, Sinembah Tanjung Muda (STM) Hilir, Deli Serdang Regency. The promotional media for Ergendang Cave still exhibits deficiencies that impede its ability to attract local tourists. The utilisation of augmented reality (AR) technology has the potential to enhance the efficacy of promotional media by facilitating the creation of portal applications that integrate the virtual and tangible realms through markerless methodologies. This Android-based application has been constructed using the Unity 3D platform and the C# (sharp) programming language, in accordance with the prototype model SDLC system development method. This study presents information on the surrounding situation of Ergendang Cave tourism with 360° panoramic photos through a portal that aims to help attract tourists. The portal provides users with the ability to virtually visit the location in real time, effectively bridging the gap between the user's physical location and the virtual representation of Goa Ergendang Tourist Attractions. This could be particularly beneficial during the ongoing pandemic, as it offers a unique opportunity for tourists to virtually experience the attractions without the need for physical travel.

Authors: Irshad Qaria Saira , Mahmood Buttar Qasim , Irshad Rabiya , Nain Qureshi Fakhra , Noor Sadia , Zarait Aqeel
Published: January 2025

Background: Acute leukemia is a malignant disorder characterized by rapid progression and systemic involvement. Ocular manifestations, including fundoscopic findings, can significantly impact vision and may serve as early indicators of systemic disease or complications. Retinal changes, such as hemorrhages or papilledema, may also hold prognostic value in the management of acute leukemia. Despite their importance, data on the frequency and patterns of these manifestations are limited, particularly in regional populations, necessitating further research to guide clinical practice.
Objective: To evaluate the frequency and associations of fundoscopic manifestations, including papilledema and retinal hemorrhages, in patients with acute leukemia.
Methods: This cross-sectional study was conducted at the Department of Oncology, PIMS, Islamabad, from 6th March 2024 to 5th September 2024. A total of 210 patients, aged 12 to 40 years, with confirmed acute leukemia based on bone marrow aspirate showing ≥20% blast cells, were included. Patients with media opacities, diabetes mellitus, sickle cell disease, HIV, or retinal vascular disease were excluded. Ophthalmologic evaluation included detailed fundoscopic examination using direct and indirect ophthalmoscopes to detect papilledema and retinal hemorrhages. Demographic and clinical data, including age, gender, BMI, disease duration, and treatment status, were recorded. Statistical analysis was performed using IBM SPSS version 24.
Results: The mean age of the patients was 24.89 ± 7.30 years, with 50% aged above 25 years. Males constituted 65.7% (n=138), while 34.3% (n=72) were females, with a male-to-female ratio of 1.9:1. Treatment-naïve patients accounted for 51.0% (n=107). Papilledema was observed in 17.6% (n=37), while retinal hemorrhages were found in 22.9% (n=48). Significant associations were noted between retinal hemorrhages and age >25 years (p=0.049) and gender (p=0.009), while no significant correlations were found for papilledema with any analyzed factors.
Conclusion: Fundoscopic findings, particularly papilledema and retinal hemorrhages, are common in patients with acute leukemia. Routine fundoscopic evaluation should be integrated into the clinical management of these patients to facilitate early detection and management of ocular complications.

Este artigo tem por objetivo avaliar a qualidade dos dados provenientes das fichas de notificações emitidas no estado do Rio de Janeiro para os acidentes por serpentes no período de 2013 a 2022, procurando observar se a relação entre a incidência dos acidentes por gênero de serpentes e o tipo de soroterapia utilizado seguiram os procedimentos recomendados pelo Ministério da Saúde. Estudo observacional, descritivo, de abordagem quantitativa com dados de incidência, utilizando dados secundários individualizados e não identificados do Sistema de Informação de Agravos de Notificação (SINAN). Destaca-se o elevado número de notificações onde a serpente não foi reconhecida, sendo esses acidentes classificados como ignorados, apesar do tratamento do acidente por animais peçonhentos estar intimamente relacionado ao animal envolvido. A ausência da informatização no preenchimento dos dados realizado de forma manual pelas Unidades de Saúde ainda é um problema no país. Fato é que se a digitação no sistema fosse descentralizada nas unidades, os erros, a falta de preenchimento de campos e inconsistências diversas poderiam ser precocemente detectadas e corrigidas. Com a implantação do e-SUS SINAN, haverá possibilidade do uso descentralizado e expressiva melhora na qualidade dos dados e na definição de prioridades na área de saúde.

The study revealed the main characteristics of the status of the Russian language in Tajikistan, such as its use in the educational environment and in public speeches, as well as the decline in its popularity in everyday communication. In conclusion, the author draws conclusions about the status and prospects of the Russian language in Tajikistan, emphasizing its importance in various spheres of life, despite changes in the political and socio-cultural context.
Linguopragmatics of the speech act of accusation in American English (using the example of the film "Green Book")
Authors: Drozdova Ekaterina Aleksandrovna
Published: January 2025

The subject of the study is the presentation of speech acts of accusation in cinematography, taking into account the discursive situation presented in the film . The object of the study is the linguopragmatics of the speech act of accusation in the American version of the English language. The author examines in detail such aspects of the topic as the expression of the act of accusation through a direct or implicit representation of a tort (crime, misconduct), the consequences of a tort, opposition to a pattern or alternative model of behavior. Special attention is paid to the issues of contextual antithesis, which runs through the entire text of the analyzed film, since the antithesis becomes the leading way of formulating an accusation and an appropriate reaction to it – a communicative act of self-defense, expressed in the denial of a tort, eliminating its seriousness and consequences. The film text emphasizes the juxtaposition of the two main characters, and the communicative antithesis accompanies their dialogues throughout the film.  The 2018 film "Green Book", which contains a large number of speech acts of accusation, was chosen as the research material. To achieve the goals of the study, all speech acts containing an accusation were isolated in the dialogues of the characters of the film using a continuous sampling method, and then the ways of its expression were analyzed. The main conclusions of the study are the revealed similarities in the communicative tactics of the two main characters: despite the significant social difference and significant differences in the lexical and syntactic content of phrases, the main characters of the film choose similar tactics to express accusations. A special contribution of the author to the study of the topic is the identification of two leading means of formulating accusations in the film discourse: the juxtaposition of "I" – "they", "you – they", "we – they" and the culminating juxtaposition in the dialogue of the two main characters "I – you", which is resolved by the happy ending of the film. The novelty of the research lies in the identification of accusation tactics in the film discourse. Previously, these speech acts were studied using the example of fiction, in which dialogues are widely amplified in the absence of visual support characteristic of the film discourse.

For the first time, the research material is the creolized texts of the cover of Der Spiegel magazine from 1946 to 1948; it is new to identify the specifics of the functioning and choice of linguistic means of the verbalized text in relation to the image and cultural and social conditions of post-war Germany. The main functions of the creolized texts of the journal and the means of their expression are determined. It was found that the traditions of the magazine's cover design were generally laid down from its first issue, however, the design and arrangement of the verbalized text changed over time. The main text stood out graphically and performed nominative, informative and presentative functions. Lexical and stylistic means are not diverse, there is practically no irony, sarcasm, puns; idioms are rarely used. Structurally, there is a wide use of noun phrases. The secondary text supplements, summarizes, clarifies the content of the main text and refers to the content of the announced journal article. The relative inexpressiveness of the verbalized part of the creolized text of the Der Spiegel cover during its formation is partly due to the lack of need to struggle to attract a wide range of readers.

Longitudinal neuroimaging studies offer valuable insight into intricate dynamics of brain development, ageing, and disease progression over time. However, prevailing analytical approaches rooted in our understanding of population variation are primarily tailored for cross-sectional studies. To fully harness the potential of longitudinal neuroimaging data, we have to develop and refine methodologies that are adapted to longitudinal designs, considering the complex interplay between population variation and individual dynamics.We build on normative modelling framework, which enables the evaluation of an individual’s position compared to a population standard. We extend this framework to evaluate an individual’s longitudinal
change
compared to the longitudinal change reflected by the (population) standard dynamics. Thus, we exploit the existing normative models pre-trained on over 58,000 individuals and adapt the framework so that they can also be used in the evaluation of longitudinal studies. Specifically, we introduce a quantitative metric termed
“z-diff”
score, which serves as an indicator of a temporal change of an individual compared to a population standard. Notably, our framework offers advantages such as flexibility in dataset size and ease of implementation.To illustrate our approach, we applied it to a longitudinal dataset of 98 patients diagnosed with early-stage schizophrenia who underwent MRI examinations shortly after diagnosis and one year later.Compared to cross-sectional analyses, which showed global thinning of grey matter at the first visit, our method revealed a significant normalisation of grey matter thickness in the frontal lobe over time. Furthermore, this result was not observed when using more traditional methods of longitudinal analysis, making our approach more sensitive to temporal changes.Overall, our framework presents a flexible and effective methodology for analysing longitudinal neuroimaging data, providing insights into the progression of a disease that would otherwise be missed when using more traditional approaches.

One in ten women in their reproductive age suffer from polycystic ovary syndrome (PCOS) that, alongside subfertility and hyperandrogenism, typically presents with increased luteinizing hormone (LH) pulsatility. As such, it is suspected that the arcuate kisspeptin (ARNKISS) neurons that represent the GnRH pulse generator are dysfunctional in PCOS. We used here in vivo GCaMP fiber photometry and other approaches to examine the behavior of the GnRH pulse generator in two mouse models of PCOS. We began with the peripubertal androgen (PPA) mouse model of PCOS but found that it had a reduction in the frequency of ARNKISS neuron synchronization events (SEs) that drive LH pulses. Examining the prenatal androgen (PNA) model of PCOS, we observed highly variable patterns of pulse generator activity with no significant differences detected in ARNKISS neuron SEs, pulsatile LH secretion, or serum testosterone, estradiol, and progesterone concentrations. However, a machine learning approach identified that the ARNKISS neurons of acyclic PNA mice continued to exhibit cyclical patterns of activity similar to that of normal mice. The frequency of ARNKISS neuron SEs was significantly increased in algorithm-identified ‘diestrous stage’ PNA mice compared to controls. In addition, ARNKISS neurons exhibited reduced feedback suppression to progesterone in PNA mice and their gonadotrophs were also less sensitive to GnRH. These observations demonstrate the importance of understanding GnRH pulse generator activity in mouse models of PCOS. The existence of cyclical GnRH pulse generator activity in the acyclic PNA mouse indicates the presence of a complex phenotype with deficits at multiple levels of the hypothalamo-pituitary-gonadal axis.

Complex brain function comprises a multitude of neural operations in parallel and often at different speeds. Each of these operations is carried out across a network of distributed brain regions. How multiple distributed processes are facilitated in parallel is largely unknown. We postulate that such processing relies on a multiplex of dynamic network patterns emerging in parallel but from different functional connectivity (FC) timescales. Given the dominance of inherently slow fMRI in network science, it is unknown whether the brain leverages such multi-timescale network dynamics.We studied FC dynamics concurrently across a breadth of timescales (from infraslow to γ-range) in rare, simultaneously recorded intracranial EEG and fMRI in humans, and source-localized scalp EEG-fMRI data. We examined spatial and temporal convergence of connectome trajectories across timescales. ‘Spatial convergence’ refers to spatially similar EEG and fMRI connectome patterns, while ‘temporal convergence’ signifies the more specific case of spatial convergence at corresponding timepoints in EEG and fMRI.We observed spatial convergence but temporal divergence across FC timescales; connectome states (recurrent FC patterns) with partial spatial similarity were found in fMRI and all EEG frequency bands, but these occurred asynchronously across FC timescales. Our findings suggest that hemodynamic and frequency-specific electrophysiological signals, while involving similar large-scale networks, represent functionally distinct connectome trajectories that operate at different FC speeds and in parallel. This multiplex is poised to enable concurrent connectivity across multiple sets of brain regions independently.
One-Lung Ventilation with Double-Lumen Tube in Decortication of Lung Abscess: A Case Report

A microbial lung infection that causes the pulmonary parenchyma to necrotise is called a lung abscess. Lung decortication can be a straightforward process, but it may also present significant challenges. To allow the underlying lung parenchyma to expand, the thick fibrinous layer must be removed from the pleural surface. Patients with long-standing empyema, pleural thickening, haemothorax, and pleural tumours are candidates for decortication. Such patients require One-Lung Ventilation (OLV), as the lung being operated on must be isolated. Complications, such as the tube becoming malpositioned or the inability to achieve unilateral isolation, are not uncommon when using a Double-Lumen Tube (DLT) due to the intrinsic challenges involved. A DLT can be utilised to accomplish OLV, which is necessary for adequate lung isolation and exposure during surgery. The present article discusses the valuable experience of managing the use of DLT in a 42-year-old male who had a lung abscess and was scheduled for lung decortication due to respiratory distress. Proper preoperative assessment and appropriate anaesthesia planning are essential for handling such cases without complications and achieving better surgical outcomes.

Published: January 2025

Lac is a commercially significant cash crop that serves as a vital source of income for millions of economically disadvantaged farmers residing in tribal-dominated forest and sub-forest regions of the country. Due to the worldwide trend towards the usage of natural products, there is a consistent demand for bio-degradable and non-toxic products made from lac in the market. However, production of this economically vital commodity is declining over the years because of alterations in precipitation patterns, recurrent droughts and floods, heightened intensity and frequency of cold waves, and surges in insect pests and diseases. Jharkhand, the largest lac producer state in the country has reflected a disappointing growth rate at -0.33% over the period of 2011-12 to 2021-22. The benefit cost ratio of 2.43 by selling stick lac to middlemen, clearly reflects the high profitability nature of lac cultivation. Considering the economic benefits of the producers and the global demand for safe natural lac cultivation, enhancement in various aspect is required.
