Bayesian nonparametric latent class analysis with different item types
Authors: Qiu Meng , Paganin Sally , Ohn Ilsang , Lin Lizhen
Published: September 2023

Traditional latent class analysis (LCA) requires deciding on the number of classes in advance. Model selection criteria are then employed to find the best number of classes by going through a class enumeration process. However, this process neglects the uncertainty of the number of classes, often leading to over- or under-fitting. Moreover, different criteria can result in different optimal models, making it challenging to reach a consensus on the best criterion. By incorporating the Dirichlet process mixture (DPM) model, Bayesian nonparametric LCA is an alternative that circumvents class enumeration by assuming an infinite number of classes and inferring the number of classes from the data. The objective of the current article is to introduce an extended DPM-LCA approach that can cluster individuals based on observed variables measured on various metrics. Through a simulation study, we evaluated the performance of the DPM-LCA in terms of model selection, parameter recovery, and classification accuracy in comparison with the conventional approach. For easy implementation, a hands-on tutorial with the R package nimble is provided. The DPM-LCA approach is illustrated using three real data examples.

Pressurized metered-dose inhalers (pMDIs) deliver life-saving medications to patients with respiratory conditions and are the most used inhaler delivery device globally. pMDIs utilize a hydrofluoroalkane (HFA), also known as an F-gas, as a propellant to facilitate the delivery of medication into the lungs. Although HFAs have minimal impact on ozone depletion, their global warming potential (GWP) is more than 1,000 times higher than CO2, bringing them in scope of the F-Gas Regulation in the European Union (EU). The pharmaceutical industry is developing solutions, including a near-zero GWP ‘next-generation propellant,’ HFO-1234ze(E). At the same time, the EU is also evaluating a restriction on per-and polyfluoroalkyl substances (PFAS) under the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation. Trifluoroacetic acid (TFA) is a persistent PFAS and a potential degradation product of HFO-1234ze(E). We quantified yield of TFA from HFO-1234ze(E) using a computational model under Europe-relevant atmospheric conditions. The modeling suggests that most HFO-1234ze(E) degrades into formyl fluoride within 20 days (≥ 85%) even at the highest examined altitude. These results suggest that TFA yield from HFO-1234ze(E) varies between 0-4% under different atmospheric conditions. In 2022, France represented the highest numbers of pMDI units sold within the EU, assuming these pMDIs had HFO-1234ze(E) as propellant, we estimate an annual rainwater TFA deposition of ~0.025 µg/L. These results demonstrate negligible formation of TFA as a degradation product of HFO-1234ze(E), further supporting its suitability as a non-persistent, non-bioaccumulative, and non-toxic future propellant for pMDI devices to safeguard access for patients to these essential medicines.

Published: September 2023

Advanced pragmatic and Theory of Mind skills are hypothesised to depend on early experience of interaction. However, we do not yet fully understand the causal pathways involved. In the current study, we explored one potential early learning mechanism by assessing whether increasing caregiver responsiveness to infant communication in turn promotes infant’s prelinguistic communicative acts. In the first wave of a larger RCT study, when their infants were around 6 months, caregivers were randomly assigned to either a communication intervention or an active control intervention focused on physical health. When infants turned 12 months, home videos (N = 125, 64 active control intervention, 61 communication intervention) were analysed for overall caregiver responsive linguistic interaction, infant pre-linguistic acts, and caregiver responses to these acts. We also examined whether these variables varied by socioeconomic circumstances. Pre-registered analyses indicated the intervention led to increases in overall caregiver linguistic responsiveness, infant communicative behaviours, and caregiver semantically contingent responses to infant communicative acts. This indicates that experience of communicating with a responsive caregiver has a causal effect on the development of the infant pre-linguistic pragmatic skills that are thought to provide the basis for later language, pragmatics and Theory of Mind.
Automatic Detection of Gaze and Smile in Children’s Video Calls

Published: September 2023

With the increasing use of video chats by children, the need for tools that facilitate the scientific study of their communicative behavior becomes more pressing. This paper investigates the automatic detection – from video calls – of two major signals in children’s social coordination: smiles and gaze. While there has been significant advancement in the field of computer vision to model such signals, very little work has been done to put these techniques to the test in the noisy, variable context of video calls, and even fewer studies (if any) have investigated children’s video calls specifically. In this paper, we provide a first exploration into this question, testing and comparing two modeling approaches: a) a feature-based approach that relies on state-of-the-art software like OpenFace for feature extraction, and b) an end-to-end approach where models are directly optimized to classify the behavior of interest from raw data. We found that using features generated by OpenFace provides a better solution in the case of smiles, whereas using simple end-to-end architectures proved to be much more helpful in the case of looking behavior. A broader goal of this preliminary work is to provide the basis for a public, comprehensive toolkit for the automatic processing of children’s communicative signals from video chat, facilitating research in children’s online multimodal interaction
Opposite perceptual biases in analogous auditory and visual tasks are unique to consonant-vowel strings and are unlikely a consequence of repetition

Published: September 2023

Despite wide reporting of a right ear (RE) advantage on dichotic listening tasks and a right visual field advantage (RVF) of visual half-field tasks, we know very little about the relationship between these perceptual biases. Previous studies that have investigated perceptual asymmetries for analogous auditory and visual consonant-vowel tasks have indicated a serendipitous finding: a RE advantage and a left visual field (LVF) advantage with poor cross-modal correlations. In this study we examined the possibility that this LVF for visual processing of consonant-vowel strings may be a consequence of repetition by examining perceptual biases in analogous auditory and visual tasks for both consonant-vowel strings and words. We replicated opposite perceptual biases for consonant-vowel strings (RE and LVF advantages). This did not extend to word stimuli where we found RE and RVF advantages. Furthermore, these perceptual biases did not differ across three experimental blocks. Thus, we can firmly conclude that this LVF is unique to consonant-vowel strings and is not a consequence of the repetition of a relatively limited number of stimuli. Finally, a test of covariances indicated cross-modal relationships between laterality indices suggesting that perceptual biases are dissociable within individuals and cluster on mode of presentation (auditory vs. visual).

Background: Imagery rescripting (IR) is a technique used in cognitive-behavioral therapy and schema therapy, the treatment process of which has not been empirically verified despite being implemented for various mental disorders. This study aims to examine the experiential process of patients who undergo IR.Methods: Schema therapy sessions were video-recorded with the consent of five patients with chronic depression. Two raters adopted the task analysis protocol to analyze the videos of seven IR sessions.Results: The following experiential process common among successful sessions with the patients was revealed: (1) recalling the episode of an adverse childhood experience, (2) expressing anger and dissatisfaction with the behavior of others during the adverse experience, (3) expressing needs that were not met during the adverse experience, (4) expressing hurt feelings due to needs that were not met during the adverse experience, (5) expressing complex emotions due to fulfillment of needs, and (6) having a sense of relief, attachment, or self-compassion. The behavioral markers of each step were identified as well.

Published: September 2023

This study examines the potential promotive (beneficial for all) and protective (stronger positive effects for children with weaker arithmetic skills in Grade 1) effects of cognitive skills, motivation, and parental factors on arithmetic skills in Grade 6 in a large Finnish sample (n=2,518). We followed a dimensional approach without using cut-offs. After controlling for Grade 1 arithmetic skills, eight promotive factors were identified: better skills in number counting, spatial relations, RAN, and nonverbal reasoning, higher self-concept in math, higher task value for math, greater persistence in homework, and no parental math difficulties. Furthermore, three protective factors were identified: number concepts, oral language, and gender. Parental support in math homework also showed a significant interaction effect, but it was not consistent with the classic protective factor model. The study offers a resilience framework for arithmetic research and draws attention to the promotive and protective factors that support arithmetic development.

Published: September 2023

As an effort to realize ideal information for companies, the implementation of reliable information technology governance is needed by companies. This study aims to audit the application of information technology governance of the goods procurement system at PT. Global Satria Aji, because the company PT. Satria Aji Global wants to check profit or loss and also wants to minimize losses related to the goods procurement system.  The problem that is often experienced by companies is a system that is deemed unable to accommodate all the data needed when incoming data increases. This study uses the COBIT 5 framework using the EDM01, APO01, APO02, APO07, DSS01 and MEA01 process domains. The calculation of the average maturity level of the six domains used is 1.58 in decimal numbers or 158% in percent. In the study it was found that the biggest discrepancy occurred in the APO01 domain where the difference between the expected conditions and the conditions that occurred reached 2.04. The recommended improvement is to provide a consistent management approach so as to enable corporate governance requirements to be met.

Authors: Farlian Galang Fachrul , Ridwansyah Ridwansyah
Published: September 2023

User Experience (UX) becomes important to explore and fulfill the needs for developing user-focused applications or products. The problems that exist to measure the level of user experience in the Digital Resident Identity (IKD) application and complaints submitted by users tend to lead to system and service quality problems in the IKD application. Then research purposes are assessed to evaluate the extent to which users can utilize and interact with the application. The method used by researchers is the User Experience Questionnaire (UEQ). UEQ is a widely used scoring methodology used to quantitatively measure user experience by administering a questionnaire to individuals that measures their subjective experiences and perceptions. Variables in UEQ, namely: efficiency, perspicuity, dependability, novelty, stimulation, and interestingness. The evaluation results of user experience in IKD applications using UEQ showed that there were 5 variables that received positive evaluation results, including attractiveness variables (mean 2.14), clarity variables (perspicuity) (mean 1.725), efficiency variables (efficiency) ( mean 1.725), accuracy variable (mean 1.525), and stimulation variable (mean 1.475). Whereas the novelty variable (mean 0.602) gets neutral evaluation results. From these results it can be used by IKD application developers to improve the user experience (user experience) of IKD applications on novelty variables by improving the appearance of applications that are more creative, inventive, and also cutting edge. The developer can pay attention to the recommendations that have been presented in this study. Parties who wish to conduct further research can use other evaluation methods such as Heuristic Evaluation.
BALANÇO AMBIENTAL SKINNERIANO: REFORÇO E PUNIÇÃO COMO GANHOS E PERDAS E REGISTRO DIGITAL

Published: September 2023

Este estudo teve como objetivo estabelecer valores e referências, pelo método de observação indutiva, com base nas ações humanas em relação ao meio ambiente, assim como da natureza em relação aos diversos tipos de ambientes. O propósito foi criar uma base para futuros registros ambientais digitais eficazes e sensíveis, com tecnologia apropriada, que considerem a perspectiva humana ou da natureza. Para essa definição lógica, utilizando a teoria comportamental skinneriana, foram considerados os conceitos de reforço e punição positivos e negativos, para explorar diversas ocorrências e suas consequências socioambientais. Por se tratar de uma teoria baseada em ações antropogênicas e ocorrências naturais, que repercutem na sociedade e no meio ambiente, causando ganhos e perdas, aprendizados e traumas, consideramos as características particulares de cada agente, humano e natureza, sem rotulagens, números singulares, abstrações generalizadas ou atribuições antropomórficas. Dessa forma, chegamos ao que chamamos de "ganhos e perdas skinnerianos" (GPs), que estabelecem valores e simbologias que podem ser registrados, definindo um equilíbrio ambiental com até dezesseis atribuições, quatro para cada agente responsável em relação ao afetado, ou seja, humano ou natureza, para o meio ambiente ou sociedade.

Skinnerian environmental balance: reinforcement and punishment as gains and losses and digital record
 
ABSTRACT: This study aimed to establish values and references through the method of inductive observation, based on human actions in relation to the environment, as well as nature's interactions within various types of environments. The purpose was to create a foundation for future effective and sensitive digital environmental records, utilizing appropriate technology, that considers the human or natural perspective. For this logical definition, employing the Skinnerian behavioral theory, concepts of positive and negative reinforcement and punishment were considered to explore various occurrences and their socio-environmental consequences. As this theory is rooted in anthropogenic actions and natural events, impacting society and the environment, causing gains and losses, learning, and traumas, the particular characteristics of each agent, human and nature, were considered without labels, singular numbers, generalized abstractions, or anthropomorphic attributions. In this manner, we arrived at what we refer to as "Skinnerian gains and losses" (GPs), which establish values and symbolisms that can be recorded, defining an environmental balance with up to sixteen attributions, four for each responsible agent in relation to the affected, namely, human or nature, environment, or society.

U radu se opisuje žargon učenika šest medresa (islamskih srednjih škola) u Bosni i Hercegovini. Zaključci su zasnovani na podacima iz četiriju vrsta izvora: jednog popisa od 35 žargonizama objavljena u listu učenika Gazi Husrev-begove medrese u Sarajevu Zemzem, tekstovima četiriju romana u kojima se opisuje život u medresi, 40 intervjua sa svršenicima medresa i 10 upitnika s otvorenim završetkom koje su popunili svršenici različitih medresa. Na osnovu dobijenih podataka ustanovljena je terminološka razlika između medresanskog diskursa, koji je zasnovan na činiocima koji se tiču profesionalne strane učenja u medresi, i medresanskog žargona u užem smislu, u kome se ispoljava kreativnost i koji nastaje kao reakcija na medresansku svakodnevicu. Zabilježeni primjeri medresanskog žargona tematski su podijeljeni na one koji se odnose na (1) osobe, (2) vjeru, obrede i islamsku terminologiju, (3) školski i internatski život, (4) grijeh i prekršaje, (5) hranu i piće, (6) odjeću, higijenu i zdravlje te (7) novac. Među jedinicama koje pripadaju navedenim grupama izdvaja se nekoliko jedinica čiji je nastanak uzrokovan učenjem arapskog jezika. Mnogi žargonizmi koje upotrebljavaju učenici medrese poznati su i govornicima iz drugih društvenih grupa, ali su mnogi, pak, odraz medresanskog načina života i nije vjerovatno da se njima služe druge društvene grupe. Njihovo postojanje potvrđuje postojanje naročita i samosvojna medresanskog žargona.

The government's policy to change Curriculum 13 to an independent learning curriculum has an effect on changing paradigms and learning objectives in general, including Islamic learning. The measure of success between students cannot be equated but instead must be independent in accordance with the independent learning curriculum concept. it is important for teachers who teach PAI subjects to be able to develop learning evaluations according to the principles and objectives of the independent learning curriculum. This study aims to analyze the challenges and opportunities of Islamic Religious Education teachers in developing Islamic Education learning instruments in the Freedom to Learn era. The results of the study show that there are implications for the independent curriculum for student assessment, namely the teacher must develop the three types of instruments needed, namely at the beginning of learning, during learning and at the end of learning. The types of assessment instruments developed at the beginning of learning can be in the form of written tests in the form of descriptions, multiple choice and checklists. Assessment instruments during learning are in the form of observation, oral and performance, while instruments for final assessment of learning can be in the form of multiple choices, descriptions and oral tests.

Published: September 2023

Psoriasis is a chronic immune-mediated skin disease frequently associated with different comorbidities, among which psoriatic arthritis stands out, with a high impact on the quality of life of patients. We have an important therapeutic arsenal that includes topical agents, phototherapy and systemic drugs. In recent years, biological therapy has brought about a true revolution in the treatment of moderate to severe psoriasis, due to its great efficacy and safety. However, it has some limitations such as its exclusively parenteral administration, its high cost and the lack of efficacy and tolerance in some cases. Therefore, based on a better knowledge of the pathophysiology of psoriasis, new therapeutic options have emerged: the small molecules. They represent an enrichment for the clinician in the therapeutic management of psoriasis. Some of those have approved indication and others under investigation.
The objective of this review is to analyze the efficacy and safety data of these molecules that include phosphodiesterase inhibitors (apremilast), Janus kinase inhibitors (tofacitinib, baricitinib), selective tyrosine kinase 2 inhibitors (deucravacitinib), agonists G protein-associated A3 adenosine receptor (piclidenoson), orphan T-gamma receptor inverse agonists (vimirogant), and sphingosine-1-phosphate receptor antagonists (ponesimod). In addition, new molecular targets are discussed. In short, the frontline of new systemic treatment for psoriasis.
Pancreaticoduodenectomy in octogenarian patients with tumors in the head of the pancreas and periampular region

Published: September 2023

Aging of the Spanish population has been demonstrated throughout the years. Thus, in the year 2021, the number of octogenarians in Spain was 2.285.352 people, confirming that Spain was the European country with the longest life expectancy (82.3 years in 2020). On the other hand, population aging has been associated with a higher incidence of tumors, including pancreatic cancer (PC) with a total number of 8,697 cases in Spain during 2021.
It has been estimated that PC will soon surpass breast cancer in Europe to become the third most common cause of cancer-related death.
Pancreaticoduodenectomy (PD) associated with chemotherapy is the standard therapy for potentially curing tumors of the pancreatic head and periampular region. However, PD is not a universally accepted therapy in octogenarian patients with pancreatic head tumors due to the presence of an associated high comorbidity and low expected survival with surgery.
On the other hand, a significant decrease in postoperative mortality and increased survival (mortality rate between 25-27% and 5-year patient survival rate of 25% during the period 1975-1985 in the past century, versus <5% of postoperative mortality and 5-year survival of 15% in the present century), has encouraged highly experienced surgeons to perform increasingly a PD for pancreatic head cancer due to the good results reported.
In this review we analyze the diagnostic procedures, indications for surgical therapy and chemotherapy, and results using PD technique in octogenarian patients suffering from tumors located in the head of the pancreas or periampular region.

Minimal change disease (MCD) is one of the main causes of idiopathic nephrotic syndrome, manifesting with intense proteinuria leading to edema and intravascular volume depletion, characterized by the absence of alterations in light microscopy and the presence of effacement of the podocyte processes in electron microscopy. Although the cause is unknown, it is believed that due to an immunologic dysregulation and modifications of the podocyte and of the proteins that constitute the cytoskeleton of this one and of the filtration diaphragm, generating an alteration in the integrity of the glomerular basement membrane and, therefore, conditioning the presence of proteinuria. IgA nephropathy (IgAN) is the most common mesangial proliferative glomerulopathy in developed countries and one of the main causes of chronic kidney disease and renal failure in Asian population, characterized by the presence of mesangial IgA deposits. The clinical presentation is extremely variable, ranging from isolated dysmorphic microhematuria to chronic deterioration of renal function. We present a rare case of these two primary glomerulopathies concomitantly in one patient. This is intended to increase medical sensitivity in the diagnosis of the coexistence of these two primary glomerulopathies as atypical presentations in clinical practice.

Environmental contamination due to synthetic dyes is a severe problem due to their adverse eco-toxicological effects. This study prepared activated carbon from H3PO4-activated rice husks (AC-RH) to adsorb methylene blue (MB) and predicted the adsorption mechanism. The AC-RH was characterized for N2 adsorption, surface functional groups, chemical compositions, and surface morphology. The activated carbon was classified to be a mesoporous material because 87% of its pore volume diameters are 3-50 nm. MB adsorption was studied under different conditions. Optimal MB adsorption occurred at pH 8, and the ideal equilibrium time was 360 min. The equilibrium adsorption was evaluated at concentrations of MB between 25 and 200 mg/L at 30°C. The Freundlich isotherm model matched the equilibrium data, and the greatest adsorption capacity of the Langmuir isotherm was 26.31 mg/g. The kinetic analysis revealed that the adsorption was pseudo-second-order, and its rate constant (k2) was higher at higher temperatures. For the thermodynamic adsorption study at 20 to 40°C, the Gibbs free energy (G) values were -6.291 to -9.197 kJ/mol, and the activation energy (Ea) was 26.248 kJ/mol: therefore, the methylene blue adsorption was spontaneous and physical. This study also revealed that the adsorption mechanisms were H-bonding, pore-filling, Yoshida H-bonding, n- interactions, electrostatic, and cation exchange.

The green paradigm is aimed at reducing negative environmental consequences and ecological threats while simultaneously eliminating waste and fostering innovative changes in the enterprise management system. This article examines the importance of utilizing green innovations as catalysts for innovative changes in the enterprise management system. Using the hypothesis method, the article analyzes the impact of green innovations on the enterprise management system. Provided the definition of green innovations as a system of novelties, technologies, products, or practices aimed at reducing negative environmental impact and enhancing sustainability. The study proposes an original research model for studying the influence of green innovations on the enterprise management system through hypothesis construction. Several hypotheses are put forward and empirically validated, including: green innovations have a positive impact on enhancing the competitive advantage of the enterprise (H1); there is a significant correlation between consumer pressure and ecological innovations (H2); there is a substantial relationship between government regulation and green innovations (H3); green innovations positively affect the quality of interactions with suppliers (external environment), company executives, and employees (internal environment) (H4); there is a strong and significant correlation between green innovations and social, environmental, and economic efficiency (H5). The article also discusses the leverage points for government influence in stimulating green innovations: the financial support; the regulatory standards; the market mechanisms; the management of innovations. It examines both the positive and negative consequences of implementing green innovations and evaluates their effectiveness in the context of social, environmental, and economic efficiency of entrepreneurial activities. The article substantiates the consequences of the impact of green innovations on the enterprise management system and provides recommendations for practical application.
