CHIRICAHUA Field Report 2021-2023 - Sky Islands and the Desert Southwest An Independent Ecological Study
Authors: gossen candace
Published: February 2024

This Chiricahua Field Report is a combination of collected data and field observations that began in November 2021 and continued on until May 2023. The Report is about ecology and connections of life. It contains information on 400+ trees in 10 diverse ecosystems including the Madrean Sky Islands and the Riparian zones of ancient sea valleys in SE Arizona. Recent season changes, warming, fires, drought, and in contrast one of the wettest years in history including more than 90 inches of snow are noted. These stories include magnificent details of a living forest in a remnant of a super-volcano, including mushrooms that change color with rainfall, endangered orchids that bloom for only one day, flowers of cacti that open for only one morning, coati that have unique tail patterns and the chance discovery of jaguar prints to give hope again. One year, as a Park Ranger at Chiricahua National Monument has added insight into daily observations, we are the stewards of the past, present and future of wildness. Wildness in the animal world is reserved to only 4% of the planets millions of animals, Wildness is why people come to the National Parks and Forest, for they are the last stronghold of beauty that bears presence in each of our souls. As a Field Scientist it is all about observation over time, and if one is lucky, at the right time, in the right place, a story makes itself known. Nature is working together as allies to adapt and regrow the changing forests regenerating an ancient landscape and surviving climate change.

Understanding climate and vegetation trends and variations is essential for conservation planning and ecosystem management. These elements are shaped by regional manifestations of global climate change, impacting biodiversity conservation and dynamics. In the southern hemisphere, global climate change is partially reflected through trends in the hemispheric El Niño-Southern Oscillation (SOI) and regional oscillations such as the Indian Ocean Dipole Mode (DMI). These phenomena influence rainfall and temperature changes, making it crucial to understand their patterns and interdependencies. Appropriately analyzing these variables and their interrelations therefore requires a robust multivariate statistical model, a tool seldom employed to extract patterns in climate and vegetation time series. Widely used univariate statistical methods in this context fall short, as they do not account for interdependencies and covariation between multiple time series. State-space models, both univariate and multivariate, adeptly analyze structural time series by decomposing them into trends, cycles, seasonal, and irregular patterns. Multivariate state-space models, in particular, can provide deeper insights into trends and variations by accounting for interdependencies and covariation but are rarely used. We use both univariate and multivariate state models to uncover trends and variations in historic rainfall, temperature, and vegetation for the Greater Mara-Serengeti Ecosystem in Kenya and Tanzania and potential influences of oceanic and atmospheric oscillations. The univariate and multivariate patterns reveal several insights. For example, rainfall is bimodal, shows significant interannual variability but stable seasonality. Wet and dry seasons display strong, compensating quasi-cyclic oscillations, leading to stable annual averages. Rainfall was above average in both seasons from 2010-2020, influenced by global warming and the Indian Ocean Dipole. The ecosystem experienced recurrent severe droughts, erratic wet conditions and a substantial temperature rise over six decades (3.3 to 4.2 °C). The insights gained have important implications for developing strategies to mitigate climate change impacts on ecosystems, biodiversity, and human wellfare.

Published: February 2024

The diffusive exchange of major elements in Na-series tephrite-phonolite diffusion couples with compositions relevant to Canary Islands magmatism were determined at 300 MPa and variable H2O concentrations (0.3 to 3.3 wt.%), temperature (1150 to 1300°C) and fO2 (NNO-1.5 to NNO+1.7). Composition-dependent effective binary diffusion coefficients (D) were determined from concentration-distance profiles. Results show a wide range of diffusivities for different cations, consistently following the sequence Na >> Al >> K ≥ Mg = Fe = Ca > Si > Ti, with a mild diffusivity contrast (0.2-0.8 log units) between tephritic and phonolitic melts. Na is the fastest component, with diffusivities falling ~1.0 log unit above those of Si for any given conditions. An anomalously fast Al diffusion is observed, with DAl falling ~0.4 log units above Si and ~0.6 log units below Na, suggesting a prevalence of Al-alkalis coupling across our range of run conditions. The relationships between log D and H2O content in melt for all cations in an intermediate composition are strongly non-linear and can be fitted using an exponential function, with a convergence in diffusion coefficients for different temperature with increasing H2O contents. Thus, Arrhenius analyses result in a decrease of activation energies from 222-293 at 1.7 wt% H2O to 48-112 kJ/mol at 3.0 wt% H2O. These results provide new data on chemical interdiffusion in Na-rich, highly alkaline melts and suggest that H2O contents play a key role in increasing the chemical efficiency of magma mixing at low temperatures. The obtained dataset is used to test chemical controls of magma mixing in the El Abrigo ignmimbrite, Tenerife, where banded pumices involving basanitic-tephritic to phonolitic magmas are common in several compositionally bimodal ignimbrite units.

Published: February 2024

Social scientists rely heavily on data collected from human participants via surveys or experiments. To obtain these data, many social scientists recruit participants from opt-in online panels that provide access to large numbers of people willing to complete tasks for modest compensation. In a large study (total N=13,053), we explore nine opt-in non-probability samples of American respondents drawn from panels widely used in social science research, comparing them on three dimensions: response quality (attention, effort, honesty, speeding, and attrition), representativeness (observable demographics, measured attitude typicality, and responding to experimental treatments), and professionalism (number of studies taken, frequency of taking studies, and modality of device on which the study is taken). We document substantial variation across these samples on each dimension. Most notably, we observe a clear tradeoff between sample representativeness and response quality (particularly regarding attention), such that samples with more attentive respondents tend to be less representative, and vice versa. Even so, we find that for some samples, this tension can be largely eliminated by adding modest attention filters to more representative samples. This and other insights enable us to provide a guide to help researchers decide which online opt-in sample is optimal given one’s research question and constraints.

Authors: Ciordia Alejandro , Alcalà-i-Rams Marc , Lubbers Miranda jessica
Published: February 2024

In the context of growing polarization across Europe, the international research project “Inclusivity norms to counter polarization in European societies” (INCLUSIVITY) aims to understand current polarization dynamics in European societies and how to counter them. In particular, it examines the role that “inclusivity norms” (social norms that promote equality-based respect, dialogue, and unity) can play in mitigating polarization and promoting tolerance, inter-group contact, and cooperation. The four-year INCLUSIVITY research project, which was funded by the Volkswagen Foundation, is conducted by an international consortium of five research teams from four European countries with expertise in sociology, anthropology, and social psychology.One of these teams is the COALESCE Lab (Laboratory for the Computational Analysis of Egonetworks, Social Cohesion, and Exclusion), based at the GRAFO research group at the Department of Social and Cultural Anthropology of the Autonomous University of Barcelona (UAB). Within the project, the COALESCE Lab is responsible for conducting a study (Work Package 3) about the dynamics of political polarization in people’s everyday interpersonal networks in Catalonia (Spain). More specifically, the study analyzes how people experience and manage political differences with people around them (including family, friends, coworkers, and other acquaintances) in their everyday lives. This study is directed by Professor Miranda J. Lubbers (co-PI of the project), who designed the study and implemented it together with postdoctoral researcher Alejandro Ciordia. The study collects new data in two stages. In the first stage, in-depth interviews were held with a varied sample of 76 citizens of Catalonia, about their experiences and management of political differences in their everyday social relationships (in their “personal network”). We aimed to explore how citizens manage political differences in their relationships and which social norms they adopt when navigating these differences in their everyday lives. In the second stage, we assess the degree of societal consensus around the norms for managing ideological differences observed in the first stage, through an online survey. This survey will be conducted in 2024 with a large representative sample of the population of Catalonia.This report was written after the first stage. It summarizes the most important characteristics of the data collected for this work package through in-depth personal network interviews. It is written to inform the participants of the research and other interested people about our preliminary findings.
Use, Misuse, and Abuse of ICT in Nepalese Education Policy: A WPR Analysis
Authors: Saha Jilshan
Published: February 2024

Of late, a young school student from Mahottari's Shree Kishor Janta Madhyamik Vidhyalay, has exposed the administration's blatant deceit. He was most concerned about the conspicuous dearth of high-quality education (see this Facebook video at: https://www.facebook.com/watch?v=308978328234703). Surprisingly, the school is egregiously deficient in even the most basic conveniences required for a conducive learning atmosphere. There are glaringly insufficient restrooms, not enough clean drinking water, and even not enough teachers at this facility. The sheer pace at which the internet and digital learning, among other technological advancements, have become so crucial in today’s everyday academic practices, pedagogy and parlance has become alarming. Owing to its efficiency, reliability, and the liberalization of knowledge, as well as its functionality in addressing crises such as the most recent Covid-19 pandemic, ICT has become an essential, irreplaceable tool. Hence, this paper explores the use, abuse and misuse of Information and Communication Technology, highlighting since its inception in 2012. This study explores how Information and Communication Technology (ICT) has been incorporated into Nepal's educational approach. The study applies the "What is the Problem Represented to be?" (WPR) analytical framework to examine the policy's implementation, outcomes, potential, and challenges within Nepal's educational system. ICT adoption aims to switch from traditional to student-centered learning by 2018 to increase educational access and quality. The report underlines persistent policy implementation, teacher ICT training, public-private partnerships, and community engagement as ways to preserve the use of ICT in education. It exhorts decision-makers to ensure policy objectives are carried out effectively and encourages resource allocation to address these problems. It also emphasizes how ICT may revolutionize schooling. The study uses a thorough WPR analysis to look at how ICT has been incorporated into Nepal's educational policy, highlighting challenges, inconsistencies, and workable solutions to make the most of ICT's potential to improve educational quality and accessibility.
Mainstream Telerehabilitation: A Threat to the PT Profession or a Paradigm-Shifting Opportunity?
Authors: Lord Ferguson Sarah
Published: February 2024

Purpose:

This study explored physiotherapists’ attitudes towards telerehabilitation (TR) focusing on how TR adoption during COVID-19 impacted the physiotherapy profession and the sustained use of TR treatment models.

Method:

A survey mainly comprised of open-ended questions was administered to Canadian physiotherapists in private practice. The responses were analyzed with inductive content analysis to generate themes reflecting barriers and opportunities associated with TR.

Results:

Among barriers, the subthemes of challenges with technology, technical know-how, patient buy-in, and professional identity emerged. Among opportunities, the subthemes of patient empowerment and self-management, positive treatment outcomes, increased access, expanded skillset, and paradigm shifting emerged. A unique finding was the tension between the themes of TR threatening and narrowing physiotherapists’ professional identities versus expanding PT practice with hands-off care models enabled by TR.

Conclusions:

This study corroborated past research showing technological and know-how barriers to TR adoption and suggested that TR has moved PT practice towards less reliance on passive therapies. An important implication of the study is that while TR may facilitate a paradigm shift towards patient self-management, buy-in may impede the sustainability of TR and other hands-off treatment models.
Medicação sem prescrição em animais de companhia em Curuguaty, Abordagem da saúde única
Authors: Nuñez Garrido Cynthia Carolina , Martínez Colmán Liz , Britos Cano Aristides
Published: February 2024

The indiscriminate use of medication in animals without medical prescription is a bad practice that can lead to undesirable consequences, from inappropriate medication, to wrong dosage and frequency, and risks to the health of other animals, humans and the environment. The objective of this research was to determine the frequency of pet medication without a veterinary prescription in the municipality of Curuguaty, 2023, through an observational, descriptive, cross-sectional study carried out between August and November 2023. The random sampling technique consisted of applying a survey to 151 pet owners (dogs and cats). The following variables were evaluated: pet medication without veterinary prescription, pharmacological products used and risk perception. The analysis of results was carried out using descriptive statistics of absolute and percentage frequencies, using the SPSS statistical software. A percentage of 70.20% of people medicated their pets without a veterinary’s prescription, the most utilized pharmacological products being antiparasitics (53%), 92.70% of people acknowledging the risk. The study showed that the irrational use of medication in companion animals without a prescription carried out by a veterinarian in the population of Curuguaty is frequent, which is why we must insist on the dissemination of information about the consequences of improper usage of medication, both for animals and for public health.

This study aimed to evaluate the in vitro antibacterial activity of Baccharis dracunculifolia and Tamarindus indica L. aqueous extract, cashew nut shell liquid (CNSL) natural extracts, and clove essential oil (EO) against five species of Gram-negative ruminal bacteria. Cultures were grown in anaerobic media containing 0.1, 0.2, 0.5 and 1.0 mg mL-1 of the extracts or oils. Growth was evaluated by monitoring the optical density (OD 600 nm) at intervals of 0, 8, 12 and 24 hours of incubation at 39° C. The baccharis and tamarind aqueous extract, and CNSL natural extract inhibited the growth of Prevotella albensis, Prevotella bryantii, Treponema saccharophilum and Succinivibrio dextrinosolvens. For Prevotella ruminicola and Succinivibrio dextrinosolvens, the addition of the clove leaf EO of 1.0 mg mL-1 resulted in a greater impact on growth dynamics, with a reduction in optical density in all intervals of observations. The findings of this research establish the efficacy of natural additives aqueous extracts of baccharis and tamarind, CNSL, and clove essential oil, in antimicrobial activity in vitro against the Gram-negative ruminal bacteria analyzed.

The Methodology of Teaching Algorithms of Combinatorics: Permutations, Combinations, Arrangements
Authors: MANDARIA George
Published: February 2024

In this article we have described the methodology for teaching the algorithms of combinatorics which are often used when solving tasks of informatics. These are the economic types of tasks in which we need to select different objects, sort selected objects in some order and choose the best selection from all possible selections. The formulas of calculating number of such selections are known from mathematics, but in informatics we are interested not only in number, but also in selections themselves, which can be generated by special algorithms. In general, the number of such selections is quite large, so we need to use optimal algorithms to find the desired answer in real time. The essence of combinatoric objects is explained. It is shown how to find the desired object in optimal way. The samples and description of the corresponding algorithms are presented using the programming language C ++.

Discussing on the efficiency of land dispute settlement by administrative procedures from Case Law No. 49/2021/AL
Authors:   Faculty of Law – Dalat University, Vietnam, Le Chi Thi Bich
Published: February 2024

According to the current land law, a land dispute in which the involved parties do not have documents on land use rights can only choose the People's Committee or the Court to settle according to administrative procedures or civil proceedings. However, the law on the jurisdiction to settle land disputes has many shortcomings, especially the dispute settlement mechanism according to administrative procedures has not been as effective as expected. By studying and analyzing Case Law No. 49/2021/AL, the article clarifies difficulties in determining whether the jurisdiction to settle a land dispute belongs to the People's Committee or the Court. Besides that, the article also shows problems in determining the right to initiate a lawsuit under administrative procedures or civil proceedings and evaluating the effectiveness of settling land disputes according to administrative procedures. Finally, the article gives some recommendations to improve the law on the jurisdiction to settle land disputes.

In the management and use of land, the conversion of land use rights from one subject to another for the purposes of national defense and security, for socio-economic development is an indispensable need. The regualtions of the law for this activity is a particularly important content of land law. In the context of a market economy and the practice of legal regulation through the Land Law 1993, the Land Law 2003, and the Land Law 2013, the mechanisms of land conversion includes: (1) Coercive land coordination mechanisms (The State uses public power to take the land use rights from one person to give it to another; (2) Voluntary land coordination mechanism (subjects agree to transfer land use rights from one person to another through civil transactions on land use rights). As land coordination mechanisms are a relatively birad issue, this paper focuses on suggestions for the following regulations: - The role of land conversion mechanisms through civil transactions - Evaluation of regulations on ladn conversion mechanisms through civil transactions in the Land Law 2013 and legal issues raised by the revised Draft Land Law. - Proposing solutions to improve the land mechanism through civil transactions in the Draft Amended Land Law

У статті наведені результати клінічного дослідження щодо вивчення ефективності застосування препарату моксонідин у складі комплексної гіпотензивної терапії гіпертонічної хвороби II стадії (2–3 ступеня) у жінок з менопаузальним метаболічним синдромом (МПМС) порівняно з базовою комплексною гіпотензивною терапією з метою досягнення цільового рівня артеріального тиску (АТ). Розглянуто механізми антигіпертензивної дії моксонідину у складі комплексної антигіпертензивної терапії. Пацієнтки основної (16 чол.) та контрольної груп (16 чол.) стаціонарно та амбулаторно приймали базову гіпотензивну терапію препаратом трипліксам у дозі 10/2,5/10. Окрім того, пацієнтки основної групи приймали препарат центральної дії другого покоління – моксонідин у дозі 0,4 мг на добу з метою досягнення цільового рівня АТ. Дослідження проводили до і через 3 місяці після початку прийому такої комбінації. Критерієм ефективності використання моксонідину у складі комплексної терапії вважали досягнення цільового рівня АТ. Згідно з отриманими результатами, моксонідин у складі комплексної гіпотензивної терапії сприяв досягненню цільового рівня АТ у 87,9% жінок основної групи. Через 3 місяці лікування зниження систолічного АТ становило 30 мм рт.ст, діастолічного − 24,9 мм рт.ст. Доведено, що ступінь зниження артеріального тиску (АТ) під впливом комбінації моксонідин/трипліксам забезпечує суттєвий гіпотензивний ефект у пацієнток з метаболічним синдромом у менопаузі з важкою артеріальною гіпертензією. Окрім того, моксонідин зменшував варіабельність систолічного АТ протягом доби. Гіпотензивна дія моксонідину реалізувалась на фоні покращення показників ліпідного та вуглеводного обмінів. У дослідженні було показано, що моксонідин знижував частоту серцевих скорочень у пацієнток із гіперактивністю симпатичної нервової системи, позитивно впливаючи на рівень АТ протягом доби. Під час дослідження оцінювали безпечність моксонідину в комбінації з базовою терапією.
Some reflections on the capitalist labour process, nature and social reproduction
Authors: Baglioni Elena
Published: February 2024

This article suggests that Labour Process Theory (LPT) could engage more substantially with the spheres of ecology and social reproduction. By drawing on ecological and feminist Marxist literatures, it seeks to recast a materialist analysis of the capitalist labour process, which is reconstructed as an ecological process as well as a process structurally shaped by spaces and institutions where the social reproduction of workers and the working class take place. Drawing from the collective and individual work done over the last few years within these areas, the article translates abstract observations in more operative analytical categories by reinstating the relevance of socio-ecological indeterminacy of the labour process, the materiality of the body, the commodity and the workplace, the intertwining between exploitation and disciplining and by introducing the notion of reproductive subsumption.
Fuzzy Optimization Model of an Incremental Capacity Auction Formulation with GHG Consideration
Authors: Bhachu Karanveer
Published: February 2024

An incremental capacity auction (ICA) is a mechanism to procure future generation capacity in a power system. Greenhouse gas (GHG) emissions from generators negatively affect our climate and there is a real need to reduce them. Thus, it is critically important for ICA models to procure future generation capacity that reduces GHG emissions. In this thesis, we propose two ICA models incorporating energy-limited generation (renewables and storage) and a GHG emission constraint. All offers are converted into unforced capacity, negating any effect of energy limitations of generation offers. The first ICA model uses classical optimization and considers GHG emission limits and maximizes social welfare (SW). The second ICA model uses a fuzzy optimization technique to simultaneously optimize the objectives of SW maximization and GHG emission minimization. Both ICA models are tested on two datasets, a 10 and 338 capacity supply offer case which are constructed using Ontario data. While both models control GHG emissions as desired, the ICA model with fuzzy optimization is shown to find a better balance between maximizing net SW and minimizing GHG emissions. This is seen by the superior reductions in GHG emissions ranging from 33.36% up to 484.8% at the expense of minor decreases in SW ranging from 0.745% to 6.98%. Results demonstrate how GHG emission reduction results in increased selection of low carbon generation.
DTI Metrics Correlation to FLAIR Biomarkers, Cognition, and Neurodegenerative Diseases
Authors: Khan Muhammad Usama
Published: February 2024

A novel approach was proposed to correlate Diffusion Tensor Imaging (DTI) biomarkers to FLAIR biomarkers in normal appearing brain matter regions (NABM). In this work, we also investigated the relation of the NABM region to cognition and used the NABM region to show the difference between different forms of dementia, emphasizing mild cognitive impairment, and vascular mild cognitive impairment. Mean Diffusivity (MD) was used as the metric of choice for NABM analysis. The DTI to FLAIR correlation analysis found MD to be highly correlated (p<0.05) to FLAIR biomarkers with the highest correlations seen between MD and Microstructural integrity, Macro and Microstructural Damage and NABM to ICV Volume Ratio. We concluded that the NABM region can be effectively correlated with FLAIR biomarkers, be used to differentiate between mild cognitive impairment and vascular mild cognitive impairment, however it did not show statistical significance to cognition though it did follow expected trends.
Detection of Green Roofs through Satellite Imagery Using Faster R-CNN
Authors: Marcos Luzalen
Published: February 2024

With the threat of global warming, there is a need to implement sustainable solutions. Due to urbanization, forests and other natural resources that could have helped reduce carbon emissions are being depleted. Thus, cities, like Toronto, experience urban heat island effects, food shortages and increased carbon emissions. To help solve this, Green Roofs are encouraged to be implemented in Toronto to help reduce the mentioned issues. In addition, green roofs are difficult to maintain and COVID-19 making it more difficult for urban farmers to physically go and check the green roofs. Hence, this study proposes to use deep learning in detecting green roofs from satellite imagery. The approach uses NDVI values and Toronto Building data to obtain green roof locations. From here, satellite images were taken from map services such as Google Earth Pro and ArcGIS Pro. The images were preprocessed and fed into Faster R-CNN model to detect green roofs. Since this is a first step in creating a system that can monitor the Green Roof Food-Energy-Water nexus, in the future, the behaviour of Faster R-CNN with Toronto Roof Satellite Images was observed. It was shown that the Faster R-CNN provided a higher validation accuracy and higher confidence score than the Fast R-CNN. Additionally, it is suggested that the current Faster R-CNN model needs to be improved, to precisely detect green roofs in different image resolutions and dimensions.
Flair MRI Biomarkers of the Normal Appearing Brain Matter are Related to Cognition
Authors: Bahsoun Mohamad-Ali
Published: February 2024

A novel biomarker panel was proposed to quantify macro and microstructural biomarkers from the normal-appearing brain matter (NABM) in multi-centre fluid-attenuation inversion recovery (FLAIR) MRI. The hypothesis was that NABM biomarkers from FLAIR MRI are related to cognition as determined by the Montreal Cognitive Assessment (MoCA). ANOVA analysis of seven biomarkers revealed significant differences between the means for three of the biomarkers in the cross-sectional and four biomarkers for all-data approaches, across all cognitive groups (p<0.01). An adjusted ANCOVA model found significant relationships between MoCA categories dependent on age and sex for four biomarkers exclusively in the all-data approach. Furthermore, quantification of microstructural changes was performed based on correlation analysis through diffusion MRI (dMRI), with up to r=0.87 (p<0.01) correlation to mean diffusivity (MD). These biomarkers demonstrate that structural differences in the NABM in FLAIR MRI are associated with cognition and that they have high potential for clinical translation.
What Factors Contribute to the Delayed Transfers in the Post Anesthetic Care Unit (PACU) at Sunnybrook Health Sciences Centre?
Authors: Afzaal Urooj
Published: February 2024

Purpose: The aim of this study is to find the main factors (medical or non-medical) causing PACU delays at Sunnybrook Health Sciences Centre using 6-months of data from Sunnybrook’s TrackOR system.

Methods: The dataset collected consisted of 8,391 medical records of surgeries conducted out of which 2,306 patients faced transfer delays, meaning the patients did not leave PACU within 5 minutes of being ready for discharge. Therefore, 2,306 data points were used for the analysis which contained a reason for delayed discharge from PACU. Multivariate linear models are used in the analysis.

Findings: The most common reasons for delays were porter problems (33.8%; n = 735) followed by assigned bed not available on time (20.4%; n = 444) and no bed on unit (15.1%, n = 327). These 3 administrative reasons account for 69.3% of PACU delays.
The impact of COVID-19 on reusable cup sharing programs: A qualitative exploration of community-based social marketing
Authors: Friedman Noah
Published: February 2024

  

This qualitative case study explores reusable cup sharing programs in the context of the COVID-19 crisis that triggered heightened hygiene concerns. These community-based programs encourage consumers to switch from disposable to reusable cups when purchasing takeaway drinks at coffee shops. Reusable cup sharing program owners worldwide were interviewed in June 2020 on the impacts of the coronavirus pandemic and how they responded to the crisis situation. A key theoretical contribution emerged by applying community-based social marketing to this crisis context. By revising the framework from a linear to a cyclical program development process, programs are better equipped to respond to changes in the external environment through continuous monitoring. This research provides practical insights for reusable cup sharing programs and other community-based programs to build resilience to future global crises.
Introducing New Disruption in Uncertain Market Environments: How Breaking Media Attention on Corporate Events Impacts Online General Sentiment
Authors: Vanderkooi Dane
Published: February 2024

This thesis proposes a novel methodology for exploring how breaking media attention on notable corporate events impacts the public sentiment surrounding a pre-introduced, potentially disruptive innovation (PPDI) in the form of online discourse. Additionally, how online sentiment changes over time is also explored. The focus on exploration enables for insight into how digital innovators may leverage social media and media attention to assist with reducing market uncertainty and plan future online promotional activities, the new product development process (NPD) and product launch. Twitter conversations surrounding the pre-introduced payment system called Diem (formerly known as Libra), a permissioned blockchain-based payment system and cryptocurrency, were analyzed. Sentiment analysis (SA) was applied to examine online breaking media attention and coverage impacts. The results suggest that breaking media attention elicits a significant change in online sentiment. Moreover, an event with a preannouncement observes an emotional momentum effect whereby sentiment accumulates across an anticipation period.
Layers of latency in social networks and their implications for comparative analyses

Published: February 2024

Animal social systems are remarkably diverse. Linking this diversity to its ecological and evolutionary drivers and consequences has been a major focus of biological research. Initial efforts have been done within groups, populations, and species. Equipped with this information, researchers are now turning to investigations of social structure that are comparative in nature. However, comparing social networks remains a considerable logistical and analytical challenge. Here we present the ‘layers of latency framework’, a conceptual framework that helps researchers to uncover and study the latent social structures that are of interest to them. We then use this conceptual framework to examine how we can tackle some of the central challenges to comparing animal social networks, focusing on differences between networks in behaviour type, sampling type, sampling effort, sampling scale and network size. For each of these focus points, we describe why and how they create challenges for comparative analyses, and we suggest potential directions for solutions. The layers of latency framework can help researchers to identify networks and features they can (or cannot) compare. In doing so, this framework facilitates advances in cross-species social network studies with the potential to generate new and important insights into the ecological and evolutionary drivers of variation in social structure across the animal kingdom.
