CB-SEM vs PLS-SEM comparison in estimating the predictors of investment intention
Authors: Vuković Marija
Published: October 2024

This paper compares different structural equation modeling approaches in estimating the predictors of investment intention. Covariance-based structural equation modeling (CB-SEM) and partial least squares structural equation modeling (PLS-SEM) techniques were compared in the estimation of the model according to the theory of planned behavior (TPB). Additionally, the consistent PLS algorithm (PLSc) was taken into consideration in the methods comparison. To determine which factors affect stock investment intention, a TPB model with attitude towards behavior, perceived behavioral control, and subjective norm as independent variables was estimated using three different approaches. The factors in the model were measured using survey indicators and the final sample included 200 Croatian residents. The results mostly show matching conclusions about the investment intention predictors, with a small difference observed in the PLS-SEM method. It can also be concluded that the factor loadings are higher according to PLS-SEM, as well as the indicators of convergent validity and reliability. On the other hand, CB-SEM shows stronger structural paths than PLS-SEM, and PLSc results are closer to those of CB-SEM. While CB-SEM shows better model fit, PLS-SEM shows high predictive power. This research further provides explanations of the differences and guidelines on when to use which approach.
Experiencing the Call of Duty: Exploring Emotions in Commercial War Games
Authors: Pattison Joseph
Published: October 2024

This article explores how players interpret and reflect on themes in mainstream war videogames, specifically the Call of Duty franchise. Scholars have long focused on the ideological content of war games, which is marked by increased collusion of military institutions with the gaming industry and assumptions about the influential capabilities of war games, in which player agency is often downplayed. This study builds on Lenoir and Caldwell’s (2018) observations that the interpretation of mainstream franchises should focus more on their attempts to create an “affective framework” that emphasises certain emotions in players. Through a thematic analysis of semi-structured interviews with 25 participants, this study found that participants outlined their discomfort in certain missions, to the point where they even altered their playstyle, suggesting that players often reflect critically on the aspects of war these games explore. This article concludes that mainstream franchises, like Call of Duty, should be considered complex cultural artefacts consisting of various layers of meaning. Rather than directly transmitting militaristic ideologies, these games craft an emotional aesthetic capable of exploring more controversial aspects of war. The key to understanding these franchises lies directly with the players themselves, which is why audiences should be treated as conscious agents who play an active role in drawing meaning from such an aesthetic.
Party Competition Over Democracy: Democracy as Electoral Issue in Germany
Authors: Kaftan Lea
Published: October 2024

Elected leaders increasingly undermine liberal democratic institutions with the support of their voters, openly challenging liberal democratic institutions in election campaigns. However, political scientists thus far have lacked the theoretical and empirical tools to study the role of elections in democratic backsliding. This article theorizes the degree to which democracy in general and liberal democracy more specifically can and should be conceptualized as valence and positional issues in multiparty electoral competitions of established liberal democracies. By investigating how German citizens and parties of the postwar period spoke about democracy per se and liberal democracy in their regional and national election manifestos, this article shows that democracy per se and liberal democracy, in particular, have been issues of different qualities in German postwar elections. While parties have used references to democracy in general as a mixed issue, showing both signs of valence and positional issues, parties’ emphasis on liberal democracy is shaped by a positional logic. Social and direct democracy have also been positional issues. Studying democracy and its various conceptions as electoral issues will help us address many important questions concerning the stability of democracies, shifting researchers’ focus to the competition of parties over citizens’ support for reforms that undermine or stabilize liberal democracy.
O Princípio da insignificância e os insignificantes
Authors: Vitagliano Daniella Capelleti
Published: October 2024

O princípio da insignificância é uma realidade que se extrai da interpretação teleológica das normas e princípios que regem a aplicação do Direito Penal, muito embora sua incidência seja rotineiramente negada na prática forense, evidenciando questões como o racismo estrutural que permeia o sistema de justiça e a falta de vontade (ou coragem) dos aplicadores do Direito de romper padrões. Evidencia-se o apego a fórmulas arcaicas e despidas de questionamentos, olvidando-se de que a conduta, para ser considerada como crime, necessita ser não apenas formal, mas também materialmente típica. O encaixe da conduta no tipo penal que protege o patrimônio não é o único requisito para que ela seja ilícita. Atualmente, em que o punitivismo parece ser a panaceia para todos os males, ser garantista soa quase ofensivo. E na sanha legislativa e da sociedade por mais punição, os pobres e negros são os alvos do sistema de justiça, que é implacável com os cidadãos considerados indesejáveis, seja pelas reminiscências da escravidão ou por não serem considerados úteis ao mercado, já que não são consumidores, sendo apontados como marginais. O princípio da lesividade deve funcionar como limitador da discricionariedade punitiva, tanto para o legislador, na escolha das condutas a serem incriminadas, como para o acusador e o julgador, no caso concreto. Urge que se promova a mudança desse paradigma, deixando para o Direito Penal as condutas que efetivamente tragam lesão aos bens tutelados, desafogando o sistema de justiça e as penitenciárias, libertando pessoas acusadas de crimes bagatelares e gerando, além de economia para o Estado pelo alto custo de manutenção daquelas, a desestigmatização.

Authors: Pramesthi Alinka , Fafurida Fafurida
Published: October 2024

The significant difference between the number of public facilities in regencies/cities and the number of public facilities in Central Java Province, which is feared to result in high inequality, is the focus of this study. The objective of this research is to determine the level of inequality in public facilities and the factors that influence the inequality of public facilities in Central Java Province. Secondary data is utilized and analyzed using the Modified Williamson Index approach and Multiple Regression Analysis. The variables employed include population growth rate, transfer income, and the Human Development Index (HDI). The analysis of the Modified Williamson Index reveals an inequality level of public facilities in Central Java Province of 0.21. The highest level of inequality in public facilities is found in Cilacap Regency, Boyolali Regency, and Kebumen Regency. The factors influencing the inequality of public facilities include the significant variable of transfer income in relation to the level of inequality in public facilities. However, the variables of population growth rate and the Human Development Index (HDI) are not significant factors in relation to the inequality of public facilities.

Published: October 2024

Public service innovation can be developed if there is synergy between the government, institutions as innovators, and the community. The purpose of this study was to measure the influence of community participation on the sustainability of public health service innovation programs in Makassar City. This type of quantitative research with data collection methods was carried out by distributing questionnaires and documentation, and data analysis using SPSS 21. The results of the significance test (t-test) showed that there was a probability value of 0.000 ≤ 0.05. This value can prove that community participation has a positive and significant effect on the sustainability of innovation. Simultaneous testing (F) obtained an F count of 908,705 and a probability of 0.000. Because sig 0.000 <0.05, it can be concluded that the community participation variable affects the sustainability of innovation. While the magnitude of the coefficient of determination (adjusted R2) = 0.695, meaning that the community participation variable affects the innovation sustainability variable by 69.5%, the remaining 30.5% is influenced by other variables not included in this research model.

Published: October 2024

This study reports an ongoing projects related to the development of interactive digital learning content which specifically designed catering to needs of low vision learners. Reviews from previous literature indicate that interactive digital learning content particularly for low vision learners is highly scarce. It was found that most of the existing interactive digital learning content focuses on the needs of general students, in which most of this courseware means too little to the low vision learners particularly in terms of information accessibility, navigationability, and pleasurability aspects. This study starts the project by designing a conceptual designed model which then validated it through expert review and prototyping method. The prototype is called Assistive Courseware for Low Vision (AC4LV) learners. User Centered Design (UCD) approach has been utilized throughout the development of AC4LV. The main aim of this study is to achieve the usefulness of the prototype to the intended user. Therefore, to investigate the usefulness of AC4LV, it has to be tested on the targeted subjects. Thus, this study presents the initial round of user experience testing related to the subjects’ behaviors and reactions on AC4LV in effort to make it as one of the effective learning tools specifically for low vision children. It is called as user experience I. In the test,eight subjects with the average age nine to 12 were involved. Subjective feedbacks were obtained through observation and interview. Overall, it was found that each of the elements in AC4LV is useful to the low vision learners. Future works of the study will report on second round of user experience testing as this study has to achieve the saturated data.

Liquidity of Bosnia and Herzegovina Institutions and its Influence on the Scope of Commercial Transactions with Small and Medium Sized Enterprises
Authors: Kozarević Emira , Mustafagić Alisa , Softić Amra
Published: October 2024

Small and medium sized enterprises (SMEs) take up over 98% of the structure of economies and are consequently the biggest creators of new jobs, innovations, economic activity, and greater social inclusion in the European Union. One of the biggest issues that SMEs face is collection of accounts receivable. Late payments in commercial transactions are made not only by private but also public sector, and that public sector entities, i.e. state institutions, are even larger generators of illiquidity compared to private companies. SMEs in BiH have certain, although insufficient, legal solutions available in combating late payment in commercial transactions. However, the fear of losing business partners overcomes their willingness to exercise their rights as creditors.
A natureza do amor em O Soldadinho de Chumbo, de Hans Christian Andersen
Authors: Torres José Wanderson Lima
Published: October 2024

O presente artigo tem como objeto de estudo o conto “O soldadinho de chumbo”, de Hans Christian Andersen. O objetivo é realizar uma análise cerrada nesta narrativa de Andersen, buscando compreender, através dos símbolos e motivos míticos, a natureza do amor ali abordada. Para isso, o estudo fundamenta-se em noções apreendidas da mitocrítica (Durand, 2003, 2012), contando ainda com o auxílio dos estudos de simbolismo e mitologia comparada (Eliade, 1996; Campbell, 2007), psicologia analítica (Jung, 2000; Von Franz, 2003), antropologia da ritualidade (Eliade, 2008; Van Gennep, 2011) e o mito do andrógeno tal como se apresenta na obra O banquete de Platão (2001). Conclui-se que Andersen, em “O soldadinho de chumbo”, foge do desfecho moralizante e conciliador de parte de sua obra; assim, apresenta, num arremate ambíguo, uma visão do amor que, não obstante dialogar com a unio mystica e o retorno à totalidade primitiva do ser tal como previsto no mito do andrógino, indica convergência com uma visão trágica de mundo.
Love as narrative drive: Level 26: dark origins and transmedia storytelling
Authors: Santos Vanessa de Carvalho , Cass Thiago Rhys Bezerra
Published: October 2024

Throughout history, the discourse surrounding love has seen myriad interpretations since ancient Greek times. In the tapestry of European literature's evolution, the novel's intimate exploration of personal realms has elevated love as a pivotal driving force shaping characters' actions. This intrinsic link between the novel and love has become a focal point for examination. Our objective is to analyze the transmedia novel Level 26: Dark Origins (2009) by Anthony E. Zuiker and Duane Swierczynski. We aim to unravel how the merging of diverse media forms enriches the narrative's exploration of love within its broader thematic framework. This novel stands as an exemplar of transmedia storytelling, seamlessly integrating traditional print narrative with immersive online video content. Drawing insights from esteemed scholars like Henry Jenkins (2009), René Girard (1961), and Erich Fromm (1956), our analysis observes the layers of love portrayed in Level 26: Dark Origins from the romantic and familial to the more shadowy and obsessive aspects. By exploring the intricate complexities of human emotions, this multimedia extension, particularly the video series, accentuates the narrative's visual storytelling prowess, offering a nuanced portrayal of love.
Hey Liberty: subjetividade feminina negra e relações de gênero em Ruby (2017), de Cynthia Bond
Authors: Silva Yasmine Sthefane Louro da , Costa Diana Barreto , Neres Welbson Carlos Sousa
Published: October 2024

A presente pesquisa tem por objetivo geral discutir sobre as questões de gênero e raça que envolvem o romance Ruby (2017), título homônimo da protagonista da obra a escritora estadunidense Cynthia Bond. Como metodologia, foi utilizado a teoria semiótica, desde a primeira etapa do Percurso Gerativo do Sentido de Greimas, utilizando o quadrado semiótico, como sugerido por Barros (2005), acerca das oposições semânticas mínimas, até o nível mais profundo, para analisar a protagonista Ruby e discorrer sobre a dualidade puta/santa e como é apresentada e ditada na obra. A fundamentação teórica é composta pelos estudos acerca do feminismo negro de Hooks (2019; 2020) e Davis (2016), e contribuições sobre o racismo nos Estados Unidos de Morrisson (2018). Como resultados, têm-se a forma como a protagonista é marginalizada pelos moradores de Liberty, e subjugada por companheiros brancos quando foge para Nova York. Como considerações finais, apresentamos que ferramentas opressivas convencem Ruby que ela jamais passará de uma meretriz, prosseguindo a manutenção dos estereótipos raciais, que negam à mulher negra sua própria existência e subjetividade.

Influence of cation exchange resin-treated thermovinified red wines on the oxidative stability and colour of rosé sparkling wines produced by blending
Authors: Postingher Gustavo , Cisilotto Bruno , Pretto Panceri Carolina , Freire Moterle Diovane , Manfroi Vitor , Ficagna Evandro
Published: October 2024

This study investigates the effect of using cation exchange resins in a red wine obtained by flash détente thermovinification on the oxidative stability of red wines and rosé sparkling wines obtained by blending the resin-treated red wine with white wine. The results show that reducing the pH of thermovinified red wines by cation exchange improves their oxidative stability and increases the intensity of the red colour, although it reduces the concentration of total anthocyanins. The analysis of metals in the wines indicates a general reduction of cations with the use of resins, which may contribute to the oxidative stability of the wines. In addition, rosé sparkling wines produced from these lower pH red wines showed greater oxidative stability over 6 months and in a forced oxidation test. These results have significant implications for the wine industry, offering new strategies to improve the production of rosé sparkling wines, which are increasingly appreciated by the market.

Published: October 2024

The proposed paper endeavors to assess the geological and geomechanical characteristics of the geothermal deep direct-use MIP 1S well, which was drilled and completed in the Appalachian basin. This evaluation is critical for streamlining drilling processes, analyzing wellbore stability, and gauging the potential for heat extraction and storage in both deep and shallow formations, respectively. To achieve this objective, a comprehensive suite of well logs is employed, supplemented by sidewall core analysis and adjacent well injection tests. The assessment encompasses the determination of continuous elastic and rock strength properties, including Young's modulus, Poisson's ratio, friction angle, unconfined compressive strength, and tensile strength. These properties are derived utilizing advanced correlations from open-hole logs, coupled with calibration against available sidewall core lab results. Subsequently, stress and pore pressure profiling are conducted, involving the calculation of overburden stress, pore pressure profiles, and magnitudes of minimum and maximum horizontal stresses, based on poroelastic equations. These calculations are further refined through calibration with direct diagnostic fracture injection tests conducted in adjacent wells. Additionally, stress directions inferred from formation image logs are compared against the fast and slow shear azimuth direction, which is determined from dipole sonic tool data. The conclusion of these efforts results in the development of a validated 1D-geomechanical model. This model undergoes analysis through wellbore stability assessments and comparisons with drilling events, such as stuck pipe occurrences, pack-offs, and cavings, as well as borehole features including image logs and multi-arm caliper data.

The 1D-geomechanical model demonstrates a high degree of agreement with wellbore observations, revealing suboptimal execution of drilling practices, particularly utilizing mist air drilling up to a depth of 8868 feet. This suboptimal execution has led to significant wellbore breakout in both shallow and intermediate sections of the well. Consequently, the wellbore diameter has been excessively widened, exceeding 4 inches from the planned 12 ¼-inch diameter to over 16 inches. Such deviations could potentially provoke significant challenges related to cementing, open-hole log data accuracy, and wellbore stability.

In drilling operations, deploying a real-time monitoring and detection model to identify early kick and loss events is essential for ensuring safety and achieving operational success. The model presented has the capability to accurately recognize various phases of the drilling process—such as active drilling, tripping in, reaming, and tripping out—from the available real-time data. Furthermore, the system must detect kick/loss events across all phases accordingly, providing operators with meaningful and reliable results. Using a smart drilling phase detection algorithm in real-time, then applying unique early kick/loss detection according to the drilling activity to achieve EKLD for the entire drilling operation. Additionally, the monitoring system is designed to address the challenge of performing complex calculations in real time, ensuring that there is no lag in the system's responsiveness. The model was validated and evaluated using real-time drilling data directly from the rig in real-time, covering the entirety of drilling operations. Field testing demonstrated its effectiveness in detecting both kick and lost circulation events across all phases of drilling, applicable especially for real-time monitoring. A comprehensive performance comparison with traditional kick detection models was conducted. This comparison shows that the model is more suitable for all phases of drilling activities, by having its unique detection and validation algorithms tailored for each activity. In conclusion, the model stands out for its ability to effectively detect kicks and losses throughout the entire drilling operation, across various drilling phases, as well as its capability to process all data in real time. The model presented in this paper represents one of the first advanced systems capable of processing real-world drilling data for the entire drilling operation. It achieves accurate and timely detection of early kicks and losses in real-time while minimizing false alarms.
Technical Evaluation of Portland-Limestone Cement as a Replacement for Ordinary Portland Cement

Published: October 2024

Portland -Limestone Cement (PLC) is becoming increasingly prevalent as a replacement for Ordinary Portland Cement (OPC) in many industries as a method to reduce carbon dioxide emissions associated with its manufacture. The construction industry has led this charge, and the oilwell cementing industry is catching up, especially in the Northeast United States, where one major cement manufacturer has replaced their commercially available Class A oilwell cement with a Class L cement containing ground limestone as a major component. This paper expands on the conventional lab testing from previously published case studies by comparing performance of OPC vs. PLC in tests that are less commonly seen in oilfield cement lab but are vital to understanding PLC's ability to provide long-term zonal isolation.

The following four tests are performed on both OPC and PLC and their results are compared. Solubility in acid mine drainage water from a mine in Ohio, set cement expansion with various concentrations of light-burned magnesium oxide expansion agent, set cement permeability, and high temperature compressive strength testing are all performed. The high temperature compressive strength testing is performed at both 250 degrees Fahrenheit and 300 degrees Fahrenheit to compare each cement's susceptibility to strength retrogression, and the tests are also performed with the addition of silica to verify that the strength of the PLC is stabilized as it is with OPC. X-ray diffraction testing is also performed on all samples after seven days of curing to show the hydration products of both OPC and PLC, with and without silica, at elevated temperatures.

The comparative results show that PLC is an adequate sealing material in many cases where OPC is currently used. Solubility of OPC and PLC are both negligible in weak acid solutions, such as acid mine drainage water. Cement matrix permeability for samples cured at 150 °F is comparable between PLC and OPC. The response of PLC to the addition of post-set expansion additives is comparable to that of OPC. The temperature stability of PLC is comparable to OPC at 200 °F and 250 °F, but at 300 °F the PLC shows compressive strength degradation which is made worse by the addition of silica.

Published: October 2024

This paper aims to investigate the geochemical impact of CO2 storage in the San Juan Basin, particularly within the Entrada Sandstone formation. It focuses on examining the importance of interactions between injected CO2 and formation minerals and fluid, investigating mineral dissolution and precipitation, and the effect of these phenomena on rock properties.

In this study, a fully compositional reservoir simulator was utilized to simulate the coupled geochemical reactions and several other trapping processes that occur during CO2 injection into the Entrada formation of the San Juan Basin. Prior to the geochemical modeling, injection and pressure data from nearby saltwater disposal wells were used to history-match the hydrodynamic model. By fine-tuning the model against field data, the geological and petrophysical properties of the integrated model were calibrated, ensuring its predictive capability. The simulation integrated reactive transport modeling, which encompasses a broad spectrum of mineral interactions and equilibrium reactions essential for an accurate depiction of geochemical alterations.

The study examined the impact of CO2 injection on fluid and rock properties. Our findings revealed that the majority of injected CO2 maintains a supercritical state, closely followed by residual trapping, which emphasizes the dominance of structural trapping and hysteresis as the key mechanisms for CO2 sequestration. Mineral trapping, in contrast, contributes minimally. Notably, despite considerable precipitation of quartz and calcite, the dissolution of other minerals counteracts it, keeping the decrease in porosity under 0.1%. Changes in ion concentration in the fluid follow the dissolution/precipitation trend of the minerals.

This research provides detailed insights into the effects of CO2 sequestration on reservoir fluid dynamics, mineral compositions, and rock attributes within the San Juan Basin. It highlights the vital role of reservoir simulation in evaluating the long-term impact and efficacy of CO2 storage with a focus on geochemical interactions, contributing valuable knowledge to the field of carbon capture and storage.

Large language model (LLM) holds the potential to facilitate advanced data analysis within the realm of Oil and Gas (O&G) operations by delivering cutting-edge performance in Natural Language Processing (NLP) tasks such as data mining in text. In this paper, we propose a novel data-driven Artificial Intelligence Augmented Intelligence strategy with LLMs to facilitate the exploration of topics for causal machine learning to understand choices under considerations. State-of-the-art LLMs are finetuned, evaluated, benchmarked, and put into practical use to understand and monitor evolving narratives and perspectives over time for trends and quantitative analytics.

Experiments show that model performance is optimized through supervised fine-tuning based on domain specific data. Methods for evaluating the fine-tuning quality and assessing semantic relevance are introduced. Fine-tuned LLMs categorize topics in the target documents, while machine learning technics normalize guideline documents to establish a baseline for benchmarking. LLMs are efficient in processing vast volumes of industry-specific data and extracting valuable insights. In the O&G industry, LLMs have the potential to improve human intelligence via Knowledge Augment Intelligence through qualitative-to-quantitative analytics.

Glymphatic dysfunction can contribute to Parkinson’s disease (PD). Obstructive sleep apnea (OSA) disturbs sleep, which is necessary for its proper function, and is frequent in PD. We investigated the glymphatic function in de novo PD and its relation to OSA. Fifty-four PD patients (mean age 58.9 ± 12.2 years) and 32 controls (mean age 59.4 ± 8.3 years) underwent polysomnography and 3T magnetic resonance imaging of the brain. Diffusion tensor imaging along the perivascular space (DTI-ALPS) was calculated using atlas-based automatic regions of interest selection. In PD ALPS-index negatively correlated with apnea-hypopnea index (rho=-0.41; p = 0.002), oxygen desaturation index (rho=-0.38; p = 0.006), sleep stage N1 (rho=-0.42; p = 0.002), and arousal index (rho=-0.24; p = 0.018), and positively correlated with sleep stage R (rho = 0.32; p = 0.023), while in controls no such correlations were observed. Glymphatic dysfunction is related to OSA severity in de novo PD but not in controls. We imply that OSA contributes to neurodegeneration via glymphatic impairment in PD.
