Published: December 2024

Não é recente a discussão sobre os desafios que enfrenta a pesquisa acadêmica no Brasil. De maior idade ainda é o leque de discursos que tentam validar práticas de engajamento, de resiliência de enfrentamento a tal realidade, discursos que partem, em especial, daqueles que vivem na seara da academia, envoltos na lida de produzir, avaliar e até de difundir conhecimento via instrumentos institucionais oficiais.  Não obstante esse cenário crítico, fica evidente que a pesquisa sobrevive e, no escopo da pesquisa linguística, nada é diferente.

Authors: Serck-Hanssen Ingrid , Solheim-Witt Marit , Anker Justin J , Sugarman Dawn E
Published: December 2024

Background

Research documents that drinking to cope behavior can be disrupted by enhancing emotion regulation and coping skills related to the experience of stress and negative affect. The Alpha Element Self-Coaching Plan incorporates principles of positive psychology and cognitive behavioral therapy to redirect negative thinking and emotions and, therefore, has the potential to benefit individuals who use alcohol to cope with stress.

Objective

This study aimed to evaluate satisfaction and usability of the web-based Alpha Element Self-Coaching Plan in order to inform the development of an expanded digital platform based on the Alpha Element framework.

Methods

Participants enrolled in the web-based program as part of their clinical care were eligible to participate. A total of 20 individuals (14 women and 6 men) between ages 30 and 79 (mean 54.5, SD 14.14) years completed web-based questionnaires to assess product performance in areas such as ease of technology use, quality of videos and handouts, and the value of the activities. Participants also completed the System Usability Scale (SUS) and provided background and demographic information, including alcohol use.

Results

Only 1 participant reported no alcohol use in the past year; 55% (11/20) of participants drank alcohol 2‐4 times per month or less and 45% (9/20) reported drinking alcohol 2‐3 times per week or more. The average SUS score of 76.38 (SD 17.85) was well above the commonly accepted threshold of 68, indicating high system usability. A majority of the sample (16/19, 84%) agreed or strongly agreed that the activities in the program inspired behavioral changes; and most agreed or strongly agreed that the program was engaging (16/20, 80%), well-organized (18/20, 90%), and easy to follow (17/20, 85%). Only 2 participants endorsed experiencing difficulty using the program on a smartphone. Suggestions for program improvements included expanding the platform, updating the web format, adding user interactivity, and enhancing navigation.

Conclusions

These data suggest that participants were generally satisfied with the web-based Alpha Element Self-Coaching Plan, and rated usability of the program as favorable. Importantly, a significant portion of participants reported that the program inspired behavioral changes. More research is needed with a larger sample to obtain specific data about alcohol consumption and investigate associations between alcohol use and program components, as well as examine gender differences. Data collected from this study will be used to expand the platform and improve user experience.
Characterizing Emergency Department Disposition Conversations for Persons Living With Dementia: Protocol for an Ethnographic Study (Preprint)
Authors: Seidenfeld Justine , Tucker Matthew , Harris-Gersten Melissa , Fix Gemmae M , Guzman Ivonne , Sperber Nina R , Hastings Susan N
Published: December 2024

BACKGROUND

Almost 40% of persons living with dementia make an emergency department (ED) visit each year. One of the most impactful and costly elements of their ED care is the decision to discharge or admit them to the hospital—the “disposition” decision. When more than one reasonable option exists regarding a health care decision, such as the decision to admit or not, it often requires a complex conversation between patients, care partners, and ED providers, ideally involving shared decision-making. However, little is known about how these conversations are conducted and the real-world context in which they take place. Best practices in ED communication and shared decision-making for persons living with dementia and their care partners are limited.

OBJECTIVE

This study aims to characterize current practices in ED disposition conversations for persons living with dementia and their care partners, informed by perspectives from patient and care partner participants.

METHODS

This study will use an ethnographic design, including direct observation methods with a semistructured data collection tool to capture the ED encounter for up to 20 patient and care partner dyads, including all discussions about dispositions. Follow-up qualitative, semistructured interviews will be conducted with persons living with dementia and their care partners to explore specific observations made during their ED encounter, and to gain insight into their perspective on their role and elements of decision support used during that conversation.

RESULTS

Data collection was initiated in October 2023, with 13 dyads recruited and observed as of July 2024. This study is expected to be completed by December 2024.

CONCLUSIONS

Novel methods can offer novel insights. By combining direct observation and follow-up interviews about an ED visit, our study design will provide insights into how ED disposition occurs in real-world settings for persons living with dementia. Findings can inform more patient-centered interventions for disposition decision-making.

Data dashboard acceptability, use, and perceived effectiveness in disseminating local overdose data and resources in a rural New York State county: A cross-sectional study (Preprint)
Authors: He Zhongxuan , Salvage Monika , Noel Corinna A
Published: December 2024

BACKGROUND

In 2023, Cayuga County, a rural county in New York State (NYS), developed and published a publicly available, interactive overdose dashboard highlighting demographic, geographic, and time trends in suspected overdoses as well as substance-use related resources in the community. Despite the widespread use of data dashboards in the overdose crisis, there is little evidence to suggest that these dashboards can effectively disseminate data and enable public health data-driven decision making, especially on a regional level. We conducted an evaluation of the Cayuga County Overdose Data Dashboard to fill this knowledge gap.

OBJECTIVE

Our study aimed to evaluate the Cayuga County Overdose Data Dashboard’s acceptability, use, and perceived effectiveness in disseminating overdose data and resources.

METHODS

Following the launch of the dashboard, an online Qualtrics survey collected feedback from individuals aged 18+ living or working in Cayuga County, asking respondents to reflect upon their experience using the dashboard. The 10-minute survey assessed usage patterns and motivations to access the dashboard as well as the dashboard’s ease of use, most valued design features, and overall perceived effectiveness in communicating information on overdoses and local resources. Data were analyzed using descriptive statistics.

RESULTS

From May to December 2023, 61 individuals from Cayuga County completed the survey, including those with lived substance use experience (13.1%) as well as their close contacts (45.9%), healthcare providers (19.7%), law enforcement (18.0%), and local public health and mental health professionals (44.3%). The user-friendly design and frequent updates facilitate engagement, as 54.1% of respondents reported accessing the dashboard at least monthly and 75.4% using to inform decision-making. Most thought the dashboard was easy to use (96.7%) and very effective in disseminating information (75.6%). From the 8 different types of overdose-related information portrayed on the dashboard, the most valued was the locations of treatment and recovery services, scoring an average of 4.75 on a 5-point scale (1=not important, 5=most important), followed by the locations of free, publicly accessible Naloxone (4.58) and trends in fatal and non-fatal overdoses (4.48).

CONCLUSIONS

Overall, this study suggests that the Cayuga County Overdose Dashboard effectively disseminates information and enables data-driven decision making in the region. When developing a community-level dashboard, our findings underscore the necessity of a user-friendly design, frequent data updates, and inclusion of key information and visuals on local overdose trends and resources.
Perspectives from Young Adults with Type 1 Diabetes Viewing Diabetes-Related Social Media: A Qualitative Study (Preprint)
Authors: Maxwell Tara , Branka Lillian , Asher Noa , Commissariat Persis , Laffel Lori
Published: December 2024

BACKGROUND

Young adults (YA) with type 1 diabetes (T1D) often struggle with self-management and achieving target glycemic control and, thus, may benefit from additional support during this challenging developmental life stage. They are also some of the highest utilizers of social media (SM), which may have some benefits to young people with T1D.

OBJECTIVE

Given the potential of online social media support for people with diabetes, we sought to use qualitative methods to explore the perceptions of diabetes social media posts to influence self-care and emotional state of YA with T1D.

METHODS

A series of Instagram posts were selected by a multidisciplinary team of T1D experts. YA aged 18-25 with T1D duration of 1 year or more were recruited from clinic to participate in a 60-minute semi-structured videoconferencing interview over HIPAA-compliant Microsoft Teams. First, they were queried about their social media use in general and specific to diabetes. Next, they reviewed 10 posts with the interviewer. For each post, their perceptions and reactions were queried. They were asked about each post’s impact on their emotional state and potential influence on diabetes self-care. Finally, they were asked to comment on what the post emphasized and how their feelings after viewing the posts. Interviews were transcribed and coded using thematic analysis. The participants’ diabetes management information was extracted from the electronic health record.

RESULTS

There were 26 YA who completed the study. Their mean (+/-standard deviation) age was 22.6+/-s2.0 years, T1D duration 12.6+/-s5.9 years, and HbA1c 7.6+/-s1.2%. In this sample, 65.3% were female and 84.6% white. All were using continuous glucose monitors (CGM) and 80.7% used insulin pumps, 71.4% of which were hybrid closed loop. All participants used SM at least once daily, but most only sometimes or rarely used SM to access diabetes content and rarely or never posted diabetes content themselves. Major themes arising from the interviews centered on the potential for the YA to connect emotionally through social media, which could be either positive or negative. Overall, for YA with T1D, social media served to: 1) highlight the existence of a community of people with T1D; 2) be a source of new diabetes information; 3) potentially influence diabetes self-management; 4) potentially influence emotional state; and 5) be appealing to the T1D community when the posts possessed certain characteristics (e.g. medical accuracy, aesthetically appealing presentation of content).

CONCLUSIONS

Social media has the potential to help YA with T1D feel a sense of community, seek and share objective and subjective thoughts and feelings about diabetes, motivate diabetes self-care, and positively affect emotional state. However, it may also have the potential to demotivate self-care and exacerbate negative emotional state with regards to diabetes.

Published: December 2024

BACKGROUND

Artificial Intelligence (AI) has the potential to transform global healthcare, with extensive application in Brazil, particularly for diagnosis (D) and screening (S).

OBJECTIVE

This study aimed to conduct a systematic review to understand AI applications in Brazilian healthcare, especially focusing on the resource-constrained environments.

METHODS

A systematic review was performed. The search strategy included the following databases: PubMed, Cochrane Library, Embase, Web of Science, LILACS, and SciELO. The search covered articles from 1993 to November 2023, with 25 articles selected for the final sample. Meta-analysis data were evaluated based on three main metrics: ROC curve, sensitivity, and specificity. A random effects model was applied for each metric to address study variability.

RESULTS

Key specialties for AI tools include ophthalmology and infectious disease, with a significant concentration of studies conducted in São Paulo state (52%). All articles included testing to evaluate and validate the tools; however, only two conducted secondary testing with a different population. In terms of risk of bias, 10 articles (40%) had medium risk, 8 articles (32%) had low risk, and 7 articles (28%) had high risk. Most studies were public initiatives, totaling 17 (68%), while 5 (20%) were private. In developing countries like Brazil, minimum technological requirements for implementing AI in healthcare must be carefully considered due to financial limitations and often insufficient technological infrastructure. Of the articles reviewed, 76% used computers, and 72% required the Windows operating system. The most used AI algorithm was Machine Learning (44%). The combined sensitivity was 0.8113, the combined specificity was 0.7417, and the combined area under the ROC curve (AUC) was 0.8308.

CONCLUSIONS

There is a relative balance in the use of both diagnostic and screening tools, with widespread application across Brazil in varied contexts. The need for secondary testing highlights opportunities for future research.

Published: December 2024

UNSTRUCTURED

Background
Social media platforms are used in contemporary crowdsourcing, and X/Twitter is apt for reaching a large number of people with a common interest. Users, especially those with small follower counts may find it challenging to reach a large audience. #AskRenal was developed as a social media crowdsourcing tool to help users get answers to nephrology questions. We hypothesized that #AskRenal hashtag could be used by anyone to receive helpful and timely responses to nephrology questions posed on a social media platform.

Study Design
We created the X/Twitter account @AskRenal and an automation software that retweeted any new posts containing the hashtag #AskRenal. Using the Symplur Healthcare Hashtag tool, we extracted and analyzed public X/Twitter content containing “#AskRenal” posted between Dec 2016 to Aug 2020. A group of 15 medical professionals reviewed #AskRenal posts individually and completed a 10-question survey for each one.

Results
During the study period, there were 17,704 tweets containing the hashtag #AskRenal and 3,099 were included in the survey analysis. About 40% (1228/3099) of #AskRenal questions were posed by users with < 1000 followers and 9% (270/3099) were from students and trainees. The questions comprised a wide range of nephrology topics. Over 75% (2386/3099) of #AskRenal questions garnered a response, and of those, answers were prompt with 69% (1644/2386) receiving a reply within 6 hours. The reviewers assessed responses to be helpful in answering the questions 83% (1978/2386) of the time. Inclusion of hyperlinks and images in replies were associated with a rating of a helpful answer (p < 0.001). Follower count was not significantly associated with the probability of obtaining a helpful answer.

Conclusion
We demonstrate that a targeted hashtag and dedicated X/Twitter account amplifying the hashtag automatically can be used to garner timely and helpful responses to nephrology questions from a wide range of individuals, irrespective of social media follower count.

Macroeconomic and firm-specific determinants of capital structure of listed firms in emerging markets
Authors: Yeboah Michael , Yeboah Benjamin , Atuahene Samuel Osei Owusu , Appiah Darko Ernest
Published: December 2024

Capital structure has attracted much attention in accounting research (Rajan & Zingales, 1995). However, factors driving capital structure keep changing (Öztekin & Flannery, 2012). Hence, this study focuses on macroeconomic and firm-specific factors that influence enterprises’ capital structure decisions in emerging markets. We conduct longitudinal research, analysing data from seven emerging market companies from 2010 to 2018. The study used either a fixed effect or random effect model for estimation, depending on the outcomes of the Hausman specification test. Firm-specific factors such as growth prospects, debt capital cost, and firm size have a substantial impact on capital structure. Macroeconomic factors such as foreign direct investment, inflation rate, and gross domestic product (GDP) growth significantly impact enterprises’ leverage. However, the impact of these characteristics varies across countries, exhibiting distinct patterns in the countries under study. Though, firm-specific and macroeconomic variables explain the capital structure, not all firm-specific and macroeconomic variables are relevant in all African countries. Understanding the elements that influence capital structure decisions can help firms optimise their financing decisions, while regulators can create effective financial regulations.
An intelligent protection scheme based on support vector machine for fault detection in microgrid using transient signals in protection scheme
Authors: Tiwari Shankarshan
Published: December 2024

Fault detection in the microgrid is a crucial task due to the diversified
fault conditions, and it must be rapidly identified to reduce any serious
hindrance to the system. The fault current behaviour due to change in fault
resistance of the touching point can damage the switches of integrated
converters. In addition to the above, sporadic conditions can also affect
the profile of voltage and current, in the system. Traditional protection
schemes need modification to prevent relay maloperation of the microgrid.
This paper presents a protection scheme based on support vector machines to
detect faults under such tedious conditions. In this protection scheme,
acquired samples of voltage and current from selected bus have been used and
processed through the data processing tool discrete wavelet transform. The
protection scheme is operating in two dissimilar operating modes, where
initially mode was identified then fault detection/classification was done.
Section identification task was performed to identify faulty sections under
varying operating scenarios. The uncertain conditions of the renewable
sources can affect the performance of the system, therefore some random
cases have been considered to validate the protection scheme.
The Role of Financial Slack as a Mediating Variable between Corporate Governance’s Effect on Company Performance
Authors: Perdanaputra Mahardika , Hersugondo Hersugondo
Published: December 2024

Amid the backdrop of the global pandemic, the economic sector has witnessed a profound transformation, with one of its notable consequences being the disruption of businesses, particularly in their struggle to access external resources. In this dynamically altered landscape, the imperative role of corporate governance practices within company management becomes pronounced. These practices are pivotal in orchestrating the efficient allocation and utilization of internal resources, evolving from a mere survival strategy to a competitive advantage, thereby bolstering overall company performance and ensuring sustained viability in the fiercely competitive modern business arena. The type of research used is descriptive research, and the research design employed is longitudinal design. The data that used for this research is 588 data from 98 listed manufacturing companies on the IDX from 2015 – 2020. All data is obtained from company financial reports and also from Bloomberg. Using multiple linear regression analysis and path analysis with SPSS version 25, the results showed that the company's internal resources (slack) could not mediate the relationship between corporate governance and company performance. This shows that company management has not been able to maximize the use of the company's internal resources (slack) in order to improve company performance. The results of this study can be used as input for company management to be able to maximize or use the company's internal resources (slack) properly in order to help the company improve its performance, because all decisions regarding the use of company resources are in the hands of company management.

“El clima de terror” en las vísperas de la procesión de la Virgen del Valle del 8 de diciembre de 1974
Authors: Perea Jorge Alberto
Published: December 2024

El 8 de diciembre de 1974 se realizó en la capital catamarqueña una procesión en honor a la Virgen del Valle. En horas de la tarde, la sagrada imagen era acompañada por miles de personas cuando se escuchó un potente ruido que indujo una repentina huida de los fieles al grito de “¡Se vienen los subversivos!”.
El hecho no era para nada sorpresivo. Los que corrían creyeron que estaban ante la presencia de un atentado explosivo.
En las semanas previas a la celebración habían circulado trascendidos, informaciones periodísticas y declaraciones que alertaban sobre una agresión “terrorista”. Según indican algunos testimonios, la mayoría de los fieles estaban inmersos en una “psicosis colectiva” inducida por una ola de rumores sobre la presencia de guerrilleros en la provincia.
Casi medio siglo después, lo ocurrido sigue sin ser recuperado por las políticas de la memoria del Estado provincial o por los relatos de las organizaciones de derechos humanos, aun cuando este hecho, a priori, reunía todas las condiciones para ser evocado como un símbolo de la violencia política que se vivió en Catamarca.
En este trabajo exponemos algunas posibles explicaciones para este “agujero” en los relatos testimoniales o académicos sobre nuestro pasado reciente local y, a partir del análisis de fuentes periodísticas y de testimonios orales, proponemos una narrativa sobre el episodio que, esperamos, contribuya a su adecuada contextualización histórica.

Published: December 2024

Este trabajo analiza la experiencia de la puesta a punto de la fábrica de producción de celdas y baterías ion-litio UniLiB, articulada entre YPF-Tecnología (Y-TEC) y la Universidad Nacional de La Plata (UNLP). Se detallan los elementos centrales, antecedentes y objetivos de UniLiB, analizando las capacidades tecno-productivas existentes en Argentina, con vistas a determinar cuáles son los insumos, partes y maquinarias que el país podría producir y cuáles serían aquellas empresas o sectores productivos que podrían participar de la cadena de valor de las baterías. Finalmente se mencionan los principales desafíos y restricciones que se enfrentan, tanto del lado de la oferta como del lado de la demanda.
Debates históricos y actuales sobre el rol de la ciencia básica en Argentina
Authors: Felsztyna Iván
Published: December 2024

En el debate público sobre la política científica suele afirmarse que el Estado debe financiar la investigación básica en las diferentes disciplinas de manera tal de contar con un reservorio de conocimientos que puedan ser luego aprovechados por la ciencia aplicada y la tecnología para generar impacto social y económico. Esta perspectiva, vinculada al modelo lineal de innovación, ha sido debatida en distintas etapas históricas de la Argentina. Este trabajo se propone contrastar posturas acerca de cuál debe ser el rol de la ciencia básica motivada por la curiosidad en un país periférico. Describe, por un lado, las miradas vinculadas al pensamiento latinoamericano en ciencia, tecnología y desarrollo de las décadas de 1960 y 1970. Posteriormente, analiza de qué manera el declive del modelo lineal y la aparición de las políticas de innovación modifican el escenario de este debate.
Modified input-to-output and control-to-output transfer functions of a non-ideal buck converter working in discontinuous conduction mode
Authors: Walczak Marcin
Published: December 2024

Small-signal models of a buck converter working in the discontinuous conduction.mode that are available in the literature usually can be divided into those which contain.a single pole and refer to non-ideal converters and those that describe ideal converters and.contain two poles. Even though the models are noticeably different they have been validated.through simulations and measurements, which suggests both of them are correct. The.purpose of this paper is to provide a comprehensive comparison of the existing models with.transient simulations done in OrCAD software and through measurements, to show that both.of the mentioned models are true for a specific set of converter parameters, and to propose.a two-pole, control-to-output and input-to-output transfer functions of a non-ideal buck.converter, that can be used in any buck converter working in discontinuous conduction mode.

Authors: PHROMFAIY Apisak , WANGSOH Natita , SURIN Prayoon
Published: December 2024

The novel concept of split demand is introduced based on the dynamic single-level lotsizing (DSLLS), called the DSLLS-split demand model. The hybrid algorithm based on the combination between Ant Lion Optimization (ALO) and Gray Wolf Optimization (GWO), called the HALGW algorithm is proposed in this study. The suitable cashew nut production planning is examined with the DSLLS-split demand model and the HALGW algorithm. Four monthly datasets including demand, production quantity, production cost and holding cost are collected from January 2020 to December 2020. Two main concepts with split demand and without split demand are compared with three different algorithms: ALO, GWO and HALGW. The results found that the HALGW algorithm with the concept of split demand provides the minimum cost, 507,910.11 baht with lowest RMSE value, 106.08 and lowest MAPE value, 0.0000115. Hence, this method may help the community enterprise in Tha Pla, Uttaradit, Thailand to manage their processes, efficiently.
A Method for Analyzing Maintenance Decisions Based on the Discrete Markov Chain
Authors: KARGAR SHOUROKI Mohammad Hossein , FALLAH NEZHAD Mohammad Saber , OWLIA Mohammad Saleh , ZARE Hasan Khademi
Published: December 2024

Production systems are stopped due to malfunctions such as rotting equipment, imbalance of rotating parts, and high vibration, which leads to loss of customers, reduction of market share and unemployment of personnel. In this research, using the absorbing Markov process, a mathematical model is formulated to analyze the maintenance policy of the production process, through which one of the four states of new, old, or failure due to deterioration or sudden failure can be allocated to the machine. It is assumed that the machine changes from one state to another with different probabilities, which are determined using a discrete Markov chain. The different maintenance policies can be analyzed to minimize the average production cost. The mathematical model is obtained using discrete Markov chain equations, and the optimal maintenance and repair policy can be analyzed by considering all types of costs, including maintenance, production, and failure costs, so that the average cost of the production process can be minimized.
Low-Cost Embedded System Design for Smart Home Automation Using RF Technology
Authors: Yavuz Erdem
Published: December 2024

Applications for smart home technologies can be described as the adaptation of control systems used in industrial areas to modern living environment of people. Home automation systems are the systematic and seamless adaptation of smart home technologies to the individual’s personal needs and desires. Smart homes encompass a range of technologies designed to cater to the needs of residents, simplifying their daily routines and contributing to a more comfortable and secure way of life. Nowadays, most buildings are constructed with expensive, builtin smart home technology. However, when it comes to old buildings without smart home technology, integrating this technology into those structures can be challenging due to the requirement for intrusive overhead wall modifications necessary for installing the technological infrastructure. In this study, a radio frequency based low-cost embedded system is designed to bring intelligent technology to existing homes or old buildings. Various sub-units have been designed and established to be situated in different places of the house. Physical events and situations that occur in the house are sensed by the sub-units and transmitted to the main control unit by means of a specially developed communication protocol via radio frequency signals. This removes the cable clutter and creates a more flexible and easy installation environment.
