A social media competitive intelligence framework for brand topic identification and customer engagement prediction
Authors: Ju Xingting 
Published: November 2024

Purpose
The COVID-19 pandemic has changed customer social media engagement behavior, which challenges the establishment of effective marketing strategies to strengthen digital communication with customers and leads to new opportunities for social media competitive intelligence analytics. This study presents a new social media competitive intelligence framework that incorporates not only the detection of brand topics before and during the COVID-19 pandemic but also the prediction of customer engagement.

Design/Methodology/Approach
A sector-based empirical study is conducted to illustrate the implementation of the proposed framework. We collected tweets generated by 23 leading American catering brands before and during the pandemic. First, we used Amazon Comprehend and Latent Dirichlet allocation (LDA) to extract sentiments and topics behind unstructured text data. Second, we trained and compared the performance of six machine learning algorithms to find the optimal classifiers.

Findings
The study reveals significant shifts in social media engagement topics following the COVID-19 pandemic. Pre-pandemic topics primarily included “Food and lifestyle”, “Promotion”, “Food ordering”, “Food time”, and “Food delivery”. During the pandemic, the topics expanded to include “Social responsibility” and “Contactless ordering”. For predicting customer engagement, the performance metrics show that Random Forest and C5.0 (C50) are generally the best-performing models, with Random Forest being particularly strong for "Likes" and “Retweets”, while C50 performs best for “Replies”.

Originality
This framework differentiates itself from existing competitive intelligence frameworks by integrating the influence of external factors, such as the COVID-19 pandemic, and expanding the analysis from topic detection to customer engagement prediction. This dual focus provides a more comprehensive approach to social media competitive intelligence.

Introduction
Treatment of hypersensitivity pneumonitis involves removal of the antigen and may include the use of immunosuppression or antifibrotic therapy. It remains unclear whether antifibrotic or immunosuppressive therapy is more beneficial in fibrotic hypersensitivity pneumonitis or if clinical markers can predict a patient’s response to therapy.

Methods
We evaluated a retrospective cohort in order to determine if certain clinical characteristics can predict physiologic improvement with immunosuppressive treatment in patients with chronic hypersensitivity pneumonitis. Patients with a diagnosis of hypersensitivity pneumonitis with a moderate, high, or definite confidence according to the American Thoracic Society criteria were included in the study.

Results
Overall immunosuppression did not lead to improvement in % predicted forced vital capacity (FVC%) and % predicted diffusion capacity (DLCO%). Patients with fibrotic hypersensitivity pneumonitis and those with familial interstitial lung disease demonstrated a decline in FVC% predicted as well as DLCO% predicted over one year and the use of immunosuppression does not modify that risk. In contrast, patients with extensive ground glass demonstrated improvement in DLCO% predicted but not FVC% predicted over one year with or without the use of immunosuppression.

Conclusion
Our study demonstrates that certain radiographic variables trend toward a significant impact on FVC% predicted as well as DLCO% predicted and suggests that antifibrotic therapy may be a better initial choice of therapy in patients with fibrotic hypersensitivity pneumonitis as decline occurred with or without the use of immunosuppression.

Background
In 2018, the treatment options for unresectable stage III non-small cell lung cancer (NSCLC) changed with durvalumab, an immune checkpoint inhibitor (ICI), which was approved for consolidation therapy following concurrent chemoradiotherapy (cCRT) without disease progression. Despite durvalumab’s clinical benefit, many patients receiving this therapy developed progression. This study evaluated treatment patterns and clinical outcomes in real-world community oncology practices for patients with unresectable stage III NSCLC who received cCRT.

Methods
This study used The US Oncology Network’s (iKnowMed) electronic health record database supplemented by chart review and included adults diagnosed with unresectable stage III NSCLC initiating cCRT between 11/01/2017 and 10/31/2019, with follow-up through 04/30/2022. cCRT included concurrent treatment with platinum-based chemotherapy and radiation therapy (+/-14 days). Real-world overall survival (rwOS) and real-world progression-free survival (rwPFS) were estimated from cCRT initiation using the Kaplan–Meier method.

Results
Among 426 patients, 61.5% received durvalumab post-cCRT (cCRT+durvalumab) and 38.5% did not (cCRT alone). Death (28.3%) and disease progression (22.2%) were the most common reasons for not initiating durvalumab. The median age for the cCRT+durvalumab and cCRT alone cohorts were 70 and 71 years, and 71.8% and 61.6% had Eastern Cooperative Oncology Group performance status of 0–1, respectively. 51.5% of cCRT+durvalumab discontinued durvalumab, primarily due to adverse events (35.8%) and disease progression (28.4%). Median rwOS was 50.2 (95% confidence interval [CI]:41.4, not reached) and 11.6 (95% CI:6.5,15.9) months for cCRT+durvalumab and cCRT alone, respectively. Median rwPFS was 28.5 (95% CI:23.3,36.4) months for cCRT+durvalumab and 6.3 (95% CI:4.3,9.3) months for cCRT alone, respectively. 23.7% (cCRT+durvalumab) and 26.2% (cCRT alone) received subsequent treatment, of which, 59.7% (cCRT+durvalumab) and 46.5% (cCRT alone) received ICI.

Conclusion
Four out of ten patients did not receive consolidation durvalumab mainly due to disease progression. Even among patients who initiated durvalumab, many patients relapsed and were retreated with ICIs. These findings underscore the need to refine treatment strategies for better outcomes in stage III unresectable NSCLC.
Predicting long-term functional anti-VEGF treatment outcomes in neovascular AMD in a real-world setting
Authors: Pfister Isabel B. , Schild Christin , Garweg Justus G. 
Published: November 2024

Purpose
To test to what degree retinal fluid (RF) after the loading phase and at the end of year 1 predicts long-term functional outcomes in neovascular macular degeneration (nAMD), as do macular (MA) atrophy, treatment density and treatment interval extension.

Methods
In this retrospective single-center cohort study, a consecutive series of eyes with treatment-naïve nAMD followed under a treat-and-extend (T&E) protocol followed over ≥2 years. Best-corrected visual acuity (BCVA), presence of retinal fluid (RF) and macular atrophy (MA) were registered along with central retinal thickness (CRT) and treatment density over time. The relationship between these variables was tested by regression analysis.

Results
A total of 433 eyes were followed for 4.9 ± 2.2 years. A series of univariate analyses were run to select the covariates for the final multivariate regression model. CRT after loading, time to dryness, intraretinal fluid and MA after one year were found to predict visual function over 2 to 5 years. A final regression model was adjusted for visual acuity (VA) at baseline and showed that CRT after loading was predictive only in the short term (2 years) and that MA had the greatest predictive value for VA after 2 to 5 years. Intraretinal fluid (IRF) significantly predicted VA only after 4 years. The final regression model explained 21 to 32% of the variation in VA.

Conclusions
In this large retrospective cohort, the presence of MA after one year was the strongest predictor of VA after 2 to 5 years, explaining a vision loss of 13 to 20 letters. The presence of IRF and SRF at any point of time had a comparably weak predictive potential for the outcomes over 5 and more years.
Determinants of depression among ever-married adolescent girls in Bangladesh: Evidence from the Bangladesh Adolescent Health and Wellbeing Survey 2019–2020
Authors: Hasan Mehedi , Al Amin Md 
Published: November 2024

Background
Common mental health disorders in early life represent a major challenge and these conditions become more complicated and substantial during the development period of adolescence. Despite the global concern over the increasing prevalence of mental health issues among adolescents, it remains largely a neglected area of research and health policy in Bangladesh, where the burden of child marriage is significantly higher. This study aimed to investigate the prevalence and factors associated with depression among married adolescent girls in Bangladesh.

Methods
The study utilized the data from first-ever Bangladesh Adolescent Health and Wellbeing Survey (BAHWS), conducted in 2019–2020. A total of 1,693 married adolescent girls were included in the final analysis. Depressive symptoms were measured using the standardized Patient Health Questionnaire-9 (PHQ-9) tool. Descriptive statistics were applied to assess the prevalence of depression, while bivariate analysis was done to measure the significance of the variables. Furthermore, logistic regression was used to examine the association between any form of depression and selected covariates.

Results
The overall prevalence of mild to severe levels of depression among the participants was 53.1% (Mild: 40.3%; Moderate: 9.9%; Moderately severe: 2.3%; Severe: 0.6%). In the multivariable logistic regression model, it was found that adolescents from richest wealth quintile were 35% less likely to suffer from depression (AOR = 0.65; 95% CI = 0.45–0.92; P value = 0.02). Additionally, physical violence (AOR = 1.55; 95% CI = 1.14–2.09; P value = 0.004), sexual harassment (AOR = 1.50; 95% CI = 1.11–2.01; P value = 0.007), social bullying (AOR = 2.25; 95% CI = 1.73–2.91; P value < .001), and cyberbullying (AOR = 1.75; 95% CI = 1.10–2.77; P value = 0.01) were associated with depression.

Conclusions
This study demonstrated that more than half of the married adolescents suffer from mild to severe levels of depression, while any form of violence and harassment significantly increases their risk of depression. Therefore, a more inclusive policy is needed, engaging with communities and local stakeholders, to lay out key actions and intervention pathways to address the issue of violence against married adolescent girls as the extent and spectrum of violence continue to evolve.

Published: November 2024

Abstract
Science is fundamental to sound policies, particularly when it comes to implementing an Ecosystem Approach. Science can and should inform nearly all facets of an Ecosystem Approach, yet challenges remain to realizing this goal. To help identify and better understand these challenges we used a qualitative comparative case study approach to identify and characterize the challenges and successes of implementing a science-driven Ecosystem Approach in the Laurentian Great Lakes. These case studies include delisting of Areas of Concern, improving coastal resilience, and addressing declining offshore lake productivity. These case studies were selected because they provide a set of very different, yet complementary, cases for assessing implementation, as well as the factors influencing the science-policy exchange. Through this comparative study, we identified a diverse set of challenges and successes, that were both systemic and case specific. Emerging from this comparative assessment were principles and enabling conditions (e.g. scale, governance, shared goals) we believe are critical to consider when establishing or improving a science-driven Ecosystem Approach.
Erich Mühsams Tanthologie – Ein literarisches Plädoyer gegen die Erbschaftspraxis im deutschen Kaiserreich
Authors: Junginger Carl 
Published: November 2024

Abstract
At first glance, Erich Mühsam’s Psychologie der Erbtante. Eine Tanthologie aus 25 Einzeldarstellungen als Beitrag zur Lösung der Unsterblichkeits-Frage (1905) seems to be apolitical and entertaining literature, ridiculing childless and husbandless Rich Aunts (Erbtanten). But as I show in a close-reading analysis, Mühsams uses this wildly known stereotype to target the bourgeois kinship and inheritance continuities of his time. The ongoing inheritance tax debates at the turn of the century provide the necessary socio-historical context to understand the satirical implications on which – so my overall hypothesis runs – both the comedy of the text and its socio-political explosiveness are based.
Konservative Transkulturalität oder Paradoxien der Moderne?
Authors: Krappmann Jörg 
Published: November 2024

Abstract
The genre of the novel of the future is usually reduced to a few canonised texts in diachronic longitudinal sections. This article, instead, attempts to explore the synchronic dynamics of the genre in the interwar period using the example of the future novels by the Austrian author Walther Eidlitz, who, after his expressionist beginnings, wrote religious-mythical texts in which a counterweight is sought against the irregularly differentiating modernity. On the eve of the Third Reich, the novels Zodiak (1930) and Das Licht der Welt (1932) outline a tableau of possibilities in which the ambivalences of modernity are named and productively integrated into a future concept of leadership based on the protagonist's search for identity, a Greek-Turkish migrant, and his negotiation processes between religion and technology as well as archaic and modern living environments.1
Visible light communication in aircraft cabins: challenges and opportunities in power, coverage, and handover management
Authors: Kumar Ajit 
Published: November 2024

Abstract
Visible light communication (VLC) presents a compelling solution for enhancing in-flight connectivity within commercial aircraft cabins. This study investigates the power distribution, coverage area, and handover performance of VLC systems inside aircraft based on line-of-sight (LoS) and first reflection signal. Results indicate that received power levels at different receiver positions are significantly affected with varying half-power semi-angles. Analysis of first reflection signal power distribution reveals maximum reflected power is achieved at semi-angle equal to 45°. Simulated coverage areas demonstrate the importance of half-power semi-angle size in determining signal confinement and separability. Handover simulations highlight the dynamic nature of passenger mobility and its impact on handover frequency, with smaller semi-angles resulting in higher handover counts. While directional transmission offers benefits such as interference mitigation and spatial reuse, it also introduces challenges related to handover frequency and coverage area. These findings underscore the need for careful optimization of VLC system designs and handover algorithms to ensure seamless connectivity and optimal performance in diverse aircraft environments.

Published: November 2024

Abstract

Objectives
To investigate the effectiveness of placing an indicator light indicating inadequate ventilation near the face mask during positive-pressure ventilation with respiratory function monitors (RFMs) in neonatal resuscitation. The study is a three-group, randomised, controlled, crossover simulation trial.

Methods
Paediatrics residents, neonatology fellows, and attending neonatologists at a single neonatal intensive care unit. A ventilation simulation with a manikin was performed three times consecutively using the same scenario with three different ventilation evaluation methods (A) RFM plus indicator light and conventional methods (heart rate and chest rise) (B) RFM and conventional methods, and (C) conventional methods alone.

Results
The ratio of gaze duration on the manikin to the total trial duration was recorded using an eye-tracking device. The proportion of trials with adequate ventilation (expiratory tidal volume [VTe], 4–10 mL/kg; peak inspiratory pressure <30 cm H2O; leak <40 %) was determined. After excluding incomplete data, 63 simulations (22 participants) were analysed. The ratios of the gaze duration on the manikin to the total trial duration were significantly different among settings A (0.60 [95 % confidence interval: 0.52–0.67] sec/sec), B (0.51 [0.43–0.59] sec/sec), and C (0.80 [0.76–0.84] sec/sec). Ventilation with adequate VTe and less leakage was more frequent in settings A and B than in setting C (adequate VTe: A, 91 %; B, 91 %; and C, 83 %; less leak: A, 76 %; B, 78 %; and C, 57 %).

Conclusions
An indicator light close to the facemask with an RFM directed the eyesight towards the manikin without compromising the ventilation quality during the simulation of neonatal resuscitation.

Abstact
Copper oxide nanoparticles (CuO NPs) have wide range of application in many fields of industry, agriculture, cosmetics, and health care with probable risk to human health. The present study was conducted to find the chronic toxicity of these nanoparticles in the vital organs. Male healthy Wister Albino rats were subjected on daily bases to 35 intraperitoneal administration of 25 nm CuO NPs (2 mg/kg). All animals were subjected to morphological, histological, histochemical, and ultrastructural examinations. Exposure to CuO NPs induced reduction in body weight gain, urine retention, back arching, and renal calculi formation. The renal tissues demonstrated tubular hydropic degeneration, glomerular hypercellularity, blood vessels congestion and dilatation, renal interstitial oedema, mitochondrial injury, and lysosomal hypertrophy. Conversely, the liver displayed hepatocyte insultation, sinusoidal dilatation, Kupffer cells hyperplasia, inflammatory cell infiltration, hepatocytes mitochondrial cristolysis, mitochondrial swelling, lysosomal hyperplasia, and nuclear alterations. Furthermore, the cardiac tissues demonstrated congestion, cardiocytes disarray, and disorganization. In addition, the neural tissue exhibited Purkinje cells degeneration and cerebral cortex spongiosis. The results suggest that CuO nanomaterials engage with the vital organs’ components, potentially leading to alterations that could affect the organs function. Further research is encouraged for better understanding the mechanisms involved in pathogenesis of CuO NPs.
