Real-World User Demographics of Three Web-Based Digital Mental Health Interventions Provided by the US Department of Veterans Affairs: Observational Study Using Web Analytics Data (Preprint)
Authors: Ryan Arthur T , Stearns-Yoder Kelly A , Brenner Lisa A
Published: October 2023

BACKGROUND

Unguided digital mental health interventions (UDMHIs) have the potential to provide low-cost and effective mental health care at scale. Controlled trials have demonstrated the efficacy of UDMHIs to address mental health symptoms and conditions. However, few previous publications have described the demographics of real-world users of UDMHIs that are freely available to the public. The US Department of Veterans Affairs has created and hosts several UDMHIs on its Veteran Training Portal website. These web-based, free-to-use, and publicly available UDMHIs include Path to Better Sleep, Anger and Irritability Management Skills, and Moving Forward, which focus on insomnia, problematic anger, and depression symptoms, respectively.

OBJECTIVE

This study aimed to examine the user demographics of these 3 UDMHIs in the year 2021. In addition, it aimed to compare the age and gender distribution of the users of those 3 UDMHIs with one another and with the age and gender distribution of the total US veteran population.

METHODS

Google Analytics was used to collect user data for each of the 3 UDMHIs. The age and gender distribution of the users of each UDMHI was compared with that of the other UDMHIs as well as with that of the overall US veteran population using chi-square tests. Information on the total number of users, the country they were in, and the devices they used to access the UDMHIs was also collected and reported.

RESULTS

In 2021, the 3 UDMHIs together recorded 29,306 unique users. The estimated age range and gender were available for 24.12% (7068/29,306) of those users. Each UDMHI’s age and gender distribution significantly differed from that of the other UDMHIs and from that of the overall US veteran population (P<.001 on all chi-square tests). Women and younger age groups were overrepresented among UDMHI users compared with the overall US veteran population. The majority of devices used to access the UDMHIs were desktop or laptop devices, although a substantial proportion of devices used were mobile devices (10,199/29,752, 34.28%). Most users (27,789/29,748, 93.41%) were located in the United States, with users from Canada, the United Kingdom, and Australia accounting for another 2.61% (775/29,748) of total users.

CONCLUSIONS

Our use of Google Analytics data provided useful information about the users of 3 free and publicly available UDMHIs provided by the US Department of Veterans Affairs. Although our findings should be considered in light of the limitations of autonomously collected web analytics data, they still offer useful information for health care policy makers, administrators, and UDMHI developers.

Health Care Trainees’ and Professionals’ Perceptions of ChatGPT in Improving Medical Knowledge Training: Rapid Survey Study (Preprint)
Authors: Hu Je-Ming , Liu Feng-Cheng , Chu Chi-Ming , Chang Yu-Tien
Published: October 2023

BACKGROUND

ChatGPT is a powerful pretrained large language model. It has both demonstrated potential and raised concerns related to knowledge translation and knowledge transfer. To apply and improve knowledge transfer in the real world, it is essential to assess the perceptions and acceptance of the users of ChatGPT-assisted training.

OBJECTIVE

We aimed to investigate the perceptions of health care trainees and professionals on ChatGPT-assisted training, using biomedical informatics as an example.

METHODS

We used purposeful sampling to include all health care undergraduate trainees and graduate professionals (n=195) from January to May 2023 in the School of Public Health at the National Defense Medical Center in Taiwan. Subjects were asked to watch a 2-minute video introducing 5 scenarios about ChatGPT-assisted training in biomedical informatics and then answer a self-designed online (web- and mobile-based) questionnaire according to the Kirkpatrick model. The survey responses were used to develop 4 constructs: “perceived knowledge acquisition,” “perceived training motivation,” “perceived training satisfaction,” and “perceived training effectiveness.” The study used structural equation modeling (SEM) to evaluate and test the structural model and hypotheses.

RESULTS

The online questionnaire response rate was 152 of 195 (78%); 88 of 152 participants (58%) were undergraduate trainees and 90 of 152 participants (59%) were women. The ages ranged from 18 to 53 years (mean 23.3, SD 6.0 years). There was no statistical difference in perceptions of training evaluation between men and women. Most participants were enthusiastic about the ChatGPT-assisted training, while the graduate professionals were more enthusiastic than undergraduate trainees. Nevertheless, some concerns were raised about potential cheating on training assessment. The average scores for knowledge acquisition, training motivation, training satisfaction, and training effectiveness were 3.84 (SD 0.80), 3.76 (SD 0.93), 3.75 (SD 0.87), and 3.72 (SD 0.91), respectively (Likert scale 1-5: strongly disagree to strongly agree). Knowledge acquisition had the highest score and training effectiveness the lowest. In the SEM results, training effectiveness was influenced predominantly by knowledge acquisition and partially met the hypotheses in the research framework. Knowledge acquisition had a direct effect on training effectiveness, training satisfaction, and training motivation, with β coefficients of .80, .87, and .97, respectively (all P<.001).

CONCLUSIONS

Most health care trainees and professionals perceived ChatGPT-assisted training as an aid in knowledge transfer. However, to improve training effectiveness, it should be combined with empirical experts for proper guidance and dual interaction. In a future study, we recommend using a larger sample size for evaluation of internet-connected large language models in medical knowledge transfer.
The Temperature Feature of ChatGPT: Modifying Creativity for Clinical Research (Preprint)
Authors: Davis Joshua , Van Bulck Liesbet , Durieux Brigitte N , Lindvall Charlotta
Published: October 2023

UNSTRUCTURED

More clinicians and researchers are exploring uses for large language model chatbots, such as ChatGPT, for research, dissemination, and educational purposes. Therefore, it becomes increasingly relevant to consider the full potential of this tool, including the special features that are currently available through the application programming interface. One of these features is a variable called temperature, which changes the degree to which randomness is involved in the model’s generated output. This is of particular interest to clinicians and researchers. By lowering this variable, one can generate more consistent outputs; by increasing it, one can receive more creative responses. For clinicians and researchers who are exploring these tools for a variety of tasks, the ability to tailor outputs to be less creative may be beneficial for work that demands consistency. Additionally, access to more creative text generation may enable scientific authors to describe their research in more general language and potentially connect with a broader public through social media. In this viewpoint, we present the temperature feature, discuss potential uses, and provide some examples.
Patient-Centered Approaches for Designing Destigmatizing Sexual Pain-Related Web-Based Platforms: Qualitative Study (Preprint)
Authors: Abdulai Abdul-Fatawu , Naghdali Hasti , Noga Heather , Yong Paul J
Published: October 2023

BACKGROUND

Sexual pain is a common but neglected disorder that affects approximately 3% to 18% of women and an unmeasured number of gender-diverse people worldwide. Despite its wide prevalence, many people feel reluctant to visit conventional health care services or disclose their symptoms due to the fear of stigmatization. To alleviate this stigma, various web-based interventions have been developed to complement and, in some cases, replace conventional sexual health interventions. However, the way these web-based interventions are developed could inadvertently reproduce, perpetuate, or exacerbate stigma among end user patients.

OBJECTIVE

The purpose of this study was to understand patients’ perspectives on how sexual pain–related web platforms can be designed to alleviate stigma or prevent the unintended effects of stigma among patients who use web-based interventions.

METHODS

Individual semistructured interviews were conducted among 16 participants with lived experiences of painful sex in a large urban city in Western Canada. Participants were recruited via social media platforms, newsletters, and a provincial health volunteer website. Using a sample sexual pain website to provide context, participants were interviewed about their experiences of stigma and how they think web platforms could be designed to address stigma. The interviews were conducted via Zoom (Zoom Technologies Inc) and analyzed using thematic analysis.

RESULTS

The findings revealed 4 overarching themes that represented participants’ perspectives on designing web platforms that may alleviate or prevent the unintended effects of stigma. These findings suggested the design of inclusive web platforms, having a nonprovocative and calming user interface, having features that facilitate connections among users and between users and providers, and displaying personal testimonials and experiences of sexual pain.

CONCLUSIONS

This study highlighted patient-centered design approaches that could serve as a reference guide in developing web platforms that alleviate or prevent the unintended effects of stigma, particularly among nonheterosexual and gender-diverse people. While this study was conducted in the context of sexual pain, the results might also apply to web platforms on other potentially stigmatizing health-related disorders or conditions.

Understanding Masculinity and Sexual Harassment for Sustainable Development
Authors: Alim Md Abdul
Published: October 2023

It is an important phenomenon to draw a common understanding of sexual harassment in a national and international concept. This applies in particular the determination to reach an agreement around a common concept definition of sexual harassment, irrespective of race, culture, and situation, form of exposure, colour, national context, and so onwards. Bangladesh has a strong legal framework to reduce violence against women; however, the law and reality are different. Women in this society are generally perceived as mothers and wives and not as equal working partners. So, women’s education has a significant impact on family income and development and the males in household activities are also absent and women’s activities are entertaining guests, preparing food, and cooking. The deep-rooted gender inequalities and discrimination makes women helpless also in the higher education level. Sexual harassment in public universities had the highest proportion of women that reported ‘never telling anyone’ about their experience of harassment by friends or teachers. This research would like to find out the ways of breaking masculinity and gender-based violence in the higher educational institution, which is authorized under the relevant disciplinary rules to take action in case of misconduct. This article will also explore the protection mechanism from sexual harassment and how the right to education and work with dignity is recognized as basic human rights in higher education levels.

Authors: Pokhrel Lal Mani
Published: October 2023

The Internet comprises a vast network of interconnected computers worldwide. It transcends limitations on information access for users and has become a vital dependency for many individuals. This study evaluates the current and potential impact of the Internet on the social lives of bachelor’s level students in Nepalgunj. It examines students’ attitudes towards interpersonal relationships and self-presentation confidence. The Internet plays a pivotal role in enhancing students’ global awareness and knowledge, but concurrently, excessive reliance on it poses a risk to their self-assurance. Data were collected via a questionnaire distributed through online platforms like Google Forms on social media. The findings reveal that 35% of students stay up late to complete college assignments, while 5% do so for family discussions. Additionally, 53% stay up late primarily to browse the Internet, and 7% do so for other reasons. The report concludes that excessive Internet use adversely affects students’ confidence, interpersonal skills, and creativity. This over-reliance diminishes social engagement and reduces the ability to confidently interact, debate, or engage face-to-face. Moreover, Internet addiction hampers students’ creativity, rendering them overly reliant on the Internet to solve challenges.

Authors: Jandrić-Kočić Marijana , Knežević Snežana
Published: October 2023

Diabetes mellitus, including type 2 diabetes, is a global health issue with less than 50% of individuals achieving optimal glycemic control. A study at Health Center Krupa na Uni, Republic Srpska, assessed adherence in 159 adults with type 2 diabetes, during the study conducted during 2019-2020. The research used a general and specific questionnaire The Adherence in Chronic Diseases Scale. Findings showed 72.9% had moderate adherence, 16.4% had low adherence, and only 10.7% had high adherence. The female gender predicted higher adherence (p=0.048). The type of oral hypoglycemic agents (p=0.520) was not associated with adherence. Older age (p=0.316) and lower education level (p=0.182) were associated with lower adherence, but not significantly. Age over 60 years and level of education had no significant effects on adherence. Although there was no statistical significance, employed respondents (p=0.076) and those living in rural areas had a higher level of adherence (p=0.064). Some respondents took medications based on their physical needs and beliefs, indicating the need to address beliefs and behaviors influencing adherence. Poor adherence remains a significant issue, and addressing adherence barriers, particularly those related to gender, can improve health outcomes for individuals with type 2 diabetes. Ongoing research and interventions are crucial to improve adherence rates and health outcomes in individuals with type 2 diabetes.

A questão territorial sempre esteve presente nos debates sobre a formatação dos direitos, essencial no desenvolvimento técnico da geopolítica e fundamental para o delineamento das discussões sobre a guerra. Mas quando aproximamos o debate da guerra, mais precisamente sobre seu impacto ao meio ambiente e como se formatam os discursos em torno dos danos ambientais, as pesquisas são poucas e/ou quase inexistentes. Para dispor um pouco sobre tal aproximação, selecionou-se a conjuntura histórica da Guerra na Ucrânia, por conta da mesma ser o conflito mais midiatizado na história da humanidade, ou seja, muitas frentes e vozes que eram silenciadas, hoje ganham visibilidade dentro das plataformas comunicativas. Nesse sentido, objetivou-se discutir sobre duas questões que são pouco analisadas conjuntamente, quais sejam: a guerra e o meio ambiente, este como vítima silenciosa dos conflitos beligerantes. Por isso, o trabalho está segmentado em duas seções centrais: o delineamento conceitual sobre a guerra e a guerra na Ucrânia e seus impactos ambientais. Para o desenvolvimento deste trabalho, utilizou-se o método hipotético-dedutivo, com abordagem qualitativa de cunho exploratório, bem como a revisão bibliográfica.

CAPITALISMO DE PLATAFORMA, "BIG TECHS" E PRECARIZAÇÃO DE DIREITOS SOCIAIS
Authors: André Avelar da Nóbrega Ricardo , Faria Pessanha Gabriel Yves
Published: October 2023

O presente artigo busca analisar os aspectos de coordenação e controle das relações sociais e laborais presentes no capitalismo de plataforma e como estas se instituem em condições de semiliberdade e de subcidadania por meio das ingerências das big techs, fomentando um cenário de coexistência entre inovações tecnológicas e intensas formas de degradação de direitos legitimadas juridicamente pelo Estado. Estas não somente têm conservado, mas também ampliado a hegemonia do capital em detrimento dos interesses daqueles que necessitam vender sua força de trabalho para garantir sua subsistência. Associado a essas questões, ressaltamos que o gerenciamento algorítmico advindo das grandes plataformas digitais - que agenciam e administram o trabalho de homens e mulheres - desdobra-se em práticas que reduzem a participação do aparato estatal em garantir direitos sociais, transferindo essas atribuições para a iniciativa privada e sua lógica mercadorizada da sociedade, típica do neoliberalismo. A partir de uma discussão teórica, buscamos evidenciar que essas práticas incidem não só na implementação de políticas públicas, como também no papel que se atribui às inovações tecnológicas e sua utilização, bem como nas condições de bem-estar na sociedade.

Published: October 2023

Um dos temas amplamente debatidos em saúde nos últimos anos é sobre a síndrome de burnout. Visto que, o estado de tensão emocional e estresse crônico provocado por condições de trabalho físicas, emocionais e psicológicas desgastantes tem gerado uma redução da realização profissional e um esgotamento mental nos trabalhadores de todas as áreas, principalmente nos profissionais de saúde que lidam diretamente com o público. Somado a isso, a pandemia de COVID-19 se tornou um grande desafio para esses funcionários da saúde, o desafio de lidar com um vírus novo que embora tenha vacina, causa muita insegurança e eles ainda precisam se adequar a escassez de equipamentos e insumos para garantir uma assistência qualificada e que consiga atender a grande demanda de pacientes infectados. Outrossim, o projeto foi realizado com objetivo de informar sobre a síndrome de burnout, importância de cuidar da saúde mental e fortalecimento de vínculo entre os colegas de equipe. Nesse viés, o projeto foi executado na Unidade Básica de Saúde e foram realizadas diversas dinâmicas de integração entre os profissionais, técnicas de respiração controlada e profunda, informações sobre a importância do exercício físico, uma boa nutrição, relevância do bom convívio nas relações trabalhistas e conhecimento sobre a síndrome de burnout, seus sinais e sintomas. Desse modo, o bem-estar mental dos profissionais saúde é essencial para um bom atendimento e convívio com a população e os colegas de trabalho, bem como para si próprio.
Hume’s Empiricism versus Kant’s Critical Philosophy (in the Times of Artificial Intelligence and the Attention Economy)
Authors: Kaluža Jernej
Published: October 2023

The article exposes how one of the most fundamental oppositions in the history of modern philosophy – the opposition between Hume’s empiricism and Kant’s critical philosophy – is embedded in the current debate on the impact of artificial intelligence (in particular, the algorithmic selection of content) on human society. Hume’s empiricism – with its deduction of subjectivity based on a process of habituation – corresponds to the functioning of recommending algorithms, while Kant’s idea of autonomous subjectivity corresponds to the ideals underlying today’s ethical attempts towards the regulation of artificial intelligence. According to such ethics, the use of empirical data can endanger humans; whereby our attention can be easily caught by sensationalist content and our autonomy replaced by the agency of machinic intelligence. However, as argued in the present article, such ethical positioning also reproduces the gap between the empirical reality and normative principles, which is why transcendental (Kantian) ethics should be supplemented with Hume’s immanent and practical reasoning.
Recreando al turista actividades consentido y para consentir
Authors: Rivera Berrío Andrés
Published: October 2023

Más allá de la mirada economicista sobre el turismo, este libro se propone rescatar la esencia del viaje turístico, mirando nuevamente hacia el turista, es decir, volviendo a los orígenes de las motivaciones que llevan a viajar. Hoy mas que nunca es necesario volver al éste como un sujeto vivencial y no como un consumista. No hacerlo significaría que no queremos avanzar hacia un turismo sustentable, el cual se constituye en imperativo social contemporáneo. Hoy se hace necesario avanzar hacia un turismo con sentido que busque proteger a las comunidades anfitrionas y a su territorio, y también hacia aquel que se enfoca en el turista vivencial, es decir, en consentir al turista, porque se enfoca en la gestión de actividades que enaltecen al turista, realzando su dimensión lúdica a través de actividades que desde la comunicación y la recreación resignifican la experiencia de viajar, promoviendo el desarrollo integral del turista. En su primer capítulo el libro presenta una novedosa caracterización de las corrientes recreacionales y cómo ellas han impactado históricamente en el desarrollo de modelos de gestión de actividades recreacionales turísticas, que hoy brindan importantes oportunidades para innovar con creatividad en nuevas formas de gestión del turismo, pero desde la emocionalidad del turista y desde la oferta de experiencias memorables para éste. Será el segundo capítulo el que permitirá proponer a manera de manual, una ruta de gestión para el diseño de actividades enfocadas en re-crear al turista a través de nuevas vivencias Finalmente, en el tercer capítulo, se ofrece la aplicación de ese manual, a partir de la experiencia desarrollada en el monumento a Cristo Rey, en Belalcázar, Caldas, la cual surgió en el marco de un Diplomado en Pastoral del Turismo impulsado por la Universidad Tecnológica de Pereira, precisamente para resignificar con la comunidad local el monumento y para redireccionar con ella su modelo de gestión turístico.

Published: October 2023

Raman spectroscopy, as a label-free sensor, is commonly used for
real-time monitoring of key parameters in the cultivation of recombinant
protein. However, ensuring accurate parameter values necessitates a
large quantity of offline measurement data, which is time-consuming and
labor-intensive. In order to address the limitations of conventional
complex data preprocessing, this study considers a genetic
algorithm-based semi-supervised convolutional neural network (GA-SCNN).
The GA-SCNN facilitates feature extraction and unsupervised sequence
labeling, and has been applied to the model system of E. coli expressing
recombinant ProA5M protein. By applying model prediction and sequence
interpolation techniques, the GA-SCNN significantly expanded the
database for glucose, lactate, ammonium ions, and OD600 from 52 to 1302
samples. A comparative analysis using standard regression algorithms has
demonstrated the superior predictive performance of the GA-SCNN
framework when dealing with a large volume of spectral data without the
requirement for preprocessing. Model cross-validation has confirmed high
accuracy and robustness in determining coefficients. In addition, a
transfer learning strategy has been employed using the OD600 data and
limited recombinant protein expression data to develop a prediction
model for the target protein. Validation experiments demonstrate good
agreement between model predictions and offline results.
A review of industrial robot predictive maintenance research in the automotive manufacturing industry
Authors: Guo Dongdong , Chen Xiangqun , Jiang Zongrui , Du Wenbo , Yu Guanghui
Published: October 2023

With the increasing automation and digitization of manufacturing
equipment, many hidden problems in industrial equipment cannot be
determined by decision-makers, often causing unexpected equipment
downtime or product quality degradation. Traditional maintenance methods
have difficulty ensuring the stability of equipment and products.
Consequently, predictive maintenance (PdM), an emerging maintenance
approach, has become an active research topic in this industry. PdM can
predict future trends and possible component failure modes based on
data-driven and mechanistic analysis, thus, providing maintenance
decisions in advance. In this study, we assessed industrial robots,
essentials in automotive manufacturing, as the research object, and
provided a comprehensive overview of industrial robot PdM. We then
discussed the status of industrial robot failure prediction model
research, analyzed the problems of various types of PdM research,
proposed constructive improvement solutions, and provided an outlook on
the future research trends of PdM.
Comparative aspects on the epoxidation of soybean oil and high oleic soybean oil
Authors: Quadros Jacyr Vianna de , Ferreira Luiz Felipe Silva , Olivieri Gustavo , Karis Dylan , Giudici Reinaldo
Published: October 2023

Soybean oil (SO) epoxidation is an extensively studied method to
generate a sustainable plasticizer for polyvinyl chloride (PVC).
Standard soybean oil is composed of triglycerides whose fatty acids are
primarily unsaturated linoleic, oleic, and linolenic acids. High oleic
soybean oil (HOSO) is collected from a soybean variety higher in oleic
acid than other acids. The present study focused on a preliminary
comparison of the epoxidation reaction behavior between SO and HOSO,
conducted isoperibolically. The experimental data were correlated by a
kinetic model. Considerable differences in the temperature and oxirane
index profiles suggest that the epoxidation of HOSO tends to be faster
and with a more intense heat release rate than the epoxidation of SO,
which was confirmed by the results of estimated kinetic constants. The
data collected and shared herein suggest that a first epoxy group
generated may cause steric hindrance to slow the epoxidation in the
second and third double bonds of the oil.
AICropCAM -- An Edge Imaging Platform with a Stack of Deep Learning Models for Plant Phenotyping
Authors: Chamara Nipuna , Bai Geng(Frank) , Ge Yufeng
Published: October 2023

We propose a solution with edge image processing and long-range
connectivity named AICropCAM that can be used in drones, ground
platforms, or as distributed sensor networks for plant phenotyping. We
have successfully run multiple image classification, segmentation, and
object detection models on this platform. Classification models help
classify images based on image quality, crop type, and phenological
stage. Object detection models could detect and count the number of
plants, weeds, and insects and expand to count the flowers, fruits, and
leaves. Segmentation models can separate the canopy from the background
and potentially segment traits that indicate the nutrient deficit or
disease. Canopy segmentation results help estimate leaf area index and
chlorophyll content. Because the models run sequentially, like a
decision tree, there is flexibility to select the most accurate model
considering the crop type and the crop’s phenological stage that helps
scan fields with multiple crops. The generated information is geo-tagged
and transmitted through low throughput long-range communication protocol
(e.g., LoRa) to cloud data storage. AICropCAM reduces 2-megabyte image
files to around 100-byte actionable data, resulting in massive savings
in data storage and transmission costs. This edge image capturing and
processing system is open to improvement with new neural network
predictive models and faster edge computers. This system provides plant
scientists and crop breeders a low-cost, flexible phenotyping tool to
extract multiple crop traits related to abiotic and biotic stress
responses.

Purpose: To study the reactogenicity, safety and immunogenicity of the Russian vaccine Flu-M in comparison with Vaxigrip vaccine for influenza prevention in children aged from 6 months to 9 years (phase III).

Materials and Methods. In 2021, a clinical study was conducted in which children aged 6 months to 9 years were immunized with Flu-M vaccine (produced by SPbSRIVS, Russia) and Vaxigrip vaccine (produced by Sanofi Pasteur S.A., France). After randomization one group of children was vaccinated with Flu-M, the other with Vaxigrip, and monitored for 180±3 days after vaccination. Children vaccinated between 3 and 9 years of age were studied in phase I, and between 6 months and 3 years of age in phase II. Tolerability and safety were assessed by the frequency and extent of adverse events, as well as by the assessment of vital signs and physical examination. Immunological efficacy assessment criteria were geometric mean antibody titer, seroconversion level, seroconversion factor, seroprotection level.

Results. Both vaccines (Flu-M and Vaxigrip) were shown to be well tolerated by children of both age groups. No serious adverse events or severe adverse events were reported   in the study. Immunological efficacy criteria were achieved for both vaccines for all strains of influenza virus in children of both age groups at 28 and 56 days after vaccination. No cases of influenza or acute respiratory infections were seen at 180±3 days postvaccination.

Conclusion. The results of the clinical study show that the Flu-M and Vaxigrip vaccines are comparable in both age groups of children.The trial is registered at ClinicalTrials.gov (NCT 05470582).

Ocena technicznej efektywności produkcji jest jednym z ważniejszych zagadnień wzbudzających zainteresowanie ekonomistów od połowy ubiegłego wieku. Jedną z metod przydatnych w tym zakresie jest Data Envelopment Analysis (DEA), pozwalająca na oszacowanie efektywności produkcji w oparciu o wyniki osiągane przez ustalony zbiór jednostek gospodarczych. Celem niniejszej pracy jest analiza dynamiki zmian technicznej efektywności produkcji w sektorze rolnictwa Unii Europejskiej (UE) z uwzględnieniem czterech podstawowych czynników produkcji, tj. pracy, ziemi, kapitału trwałego i kapitału obrotowego. Dla oceny efektywności zastosowano analizę DEA w odniesieniu do wyników ekonomicznych osiągniętych w latach 1989-2007 przez przeciętne gospodarstwa reprezentujące wybrane regiony UE. Uzyskane przeciętne techniczne efektywności w kolejnych latach badanego okresu dają podstawę dla wyznaczenia zmian efektywności w czasie, które z kolei pozwalają na uchwycenie różnic technologii produkcji na poziomie poszczególnych krajów lub ich grup. Rozwiania te uzupełnia dyskusja oparta na klasycznej analizie wykorzystania podstawowych czynników produkcji rolniczej

Authors: Popa Daniela , Timofti Elena
Published: October 2023

Development of intensive agriculture is a perspective direction in the world, but also in Moldavia. The natural factors, as well as knowledge and technology developed on this basis, ensuring a high yield, quality, competitiveness and specialization of production, will be both contributing to the development of agriculture as a branch, as well as the social efficiency of production. European integration and scientific progress offers new opportunities for raising agricultural output. The goal of the paper was to characterize perspectives of Moldavia’s agricultural sector following country’s potential accession to the European Union. As a conclusion we can say that the main factors in ensuring the competitiveness of agricultural products are quality, which manifests itself through price differentiation and diversity of sales channels.

An octahedral complex of Zn(II) with a ligand from a class of pyridine- based 1,3-selenazolyl-hydrazones was synthesized and characterized by IR and NMR spectroscopy and single crystal X-ray diffraction analysis. The purity of the complex was confirmed by elemental analysis. Two ligands are coordinated in the neutral NNN-tridentate form forming a complex cation, while the positive charge is neutralized by [ZnCl4]2-. Complex crystallizes in monoclinic C2/c space group with the Zn atoms situated in a special position. The packing features of the novel complex were analyzed using Hirshfeld surfaces, construction of 2D pseudosymmetric plot and DFT quantum mechanical calculations and compared with the previously published sulfur-based isostere. The key difference in the structures, imposed by replacement of sulfur with selenium, were identified.

Published: October 2023

Background/Aim. Postoperative nausea and vomiting (PONV) are one of the most common causes of patient dissatisfaction in the postoperative period after general anesthesia. Hyperoxia may prevent PONV after abdominal surgery, but the effectiveness of intraoperative and early postoperative hyperoxia in preventing PONV after breast cancer surgery has not been fully elucidated. The aim of this study was to assess if the application of intraoperative hyperoxia during surgery could prevent PONV. Methods. Forty female patients with breast cancer were recruited for the study, all of whom underwent surgical treatment of breast cancer with axillary sentinel node sampling or axillary lymph node dissection. A balanced general anesthesia was conducted, which was induced with propofol and maintained with sevofluran. Out of the 40 patients, 20 (in-tervention group) received a volatile gas mixture with a fraction of inspired oxygen (FiO2) of 0.8 L/min intraoperatively and, afterward, 3 L/min of oxygen via face mask for two hours after surgery. The other 20 patients (control group) received a FiO2 of 0.4 L/min during the surgery without further administration of oxygen in the early postoperative period. The presence and severity of PONV were assessed at 30 min, 4, 24, 32, 48, and 56 hrs after surgery with the use of the PONV numerical Intensity Scale by Wengritzky for evaluating clinically significant PONV in the first six hours after surgery. Data were collected in an Excel spreadsheet and analyzed using the independent Student?s t-test. Results. The overall incidence of PONV during the 30 min after the surgery was 17.5% (15% in the group of patients receiving FiO2 of 0.8 L/min and 20% in the group of patients receiving FiO2 of 0.4 L/min intraoperatively). There was no statistically significant difference between the two groups in the frequency of PONV, as well as in the severity of PONV, measured with the PONV Intensity Scale by Wengritzky (p ? 0.05). Conclusion. We found no benefit of intra- and post-operative hyperoxia in reducing the incidence of PONV. The data do not support routine administration of hyperoxia, in addition to antiemetics, for the prevention of PONV in patients undergoing breast cancer surgery.
Urinary tract infections in children with cancer and febrile neutropenia - single center experience

Published: October 2023

Background/Aim. Urinary tract infection (UTI) in children with febrile neutropenia (FN) after receiving chemotherapy could be followed by atypical symptoms and signs. The absence of routine urine culture (UC) sampling for analysis could lead to undiagnosed disease and inadequate treatment of these patients. The aim of the study was to indicate the importance of sampling UC in children who have developed FN and to point out the most probable causative agents of UTI in children with FN and antibiotic sensitivity/resistance of the isolated strains. Methods. During a five-year observation period, 40 UTIs were registered in 30 patients with FN. In the study group of patients with FN, the number of UTIs, the number of recurrent UTIs, isolated pathogens, their sensitivity to antibiotics, characteristics of urine sediment, the presence of localized symptoms of UTI, and the presence of urosepsis were analyzed. The obtained results were compared with the control group which consisted of children who were healthy prior to hospitalization due to febrile urinary infection. Results. When compared to the control group, significant differences in the presence of symptoms of UTI and urine sediment findings in patients with FN were observed. A higher percentage of resistant strains of Escherichia coli isolated from UC of cancer patients with FN was noted when compared to the control group. Three UTI cases were followed by urosepsis. Conclusion. UC findings are important not only in establishing the diagnosis of UTI and detecting multi-resistant bacterial strains but also in choosing appropriate antibiotics and selecting a subgroup of patients with recurrent UTI who require further monitoring and detecting potential complications in a timely manner.
Incorporating Data Analytics in Management Accounting: A Teaching Case on Cost Estimation
Authors: Hesford James W. , Pizzini Mina , Turner Michael J.
Published: October 2023

Management accounting tools are based on the idea that total costs are composed of fixed and variable components. Textbooks usually teach five methods to identify fixed and variables costs, including two that are outdated (scatterplot and high-low). Account analysis and industrial engineering are sometimes useful, but regression is best for its objectivity. Despite its importance, few cases address cost estimation using regression. This case requires students to use regression analysis to estimate a cost function from 108 monthly observations of unit-level data from a hotel chain. Although the case is intended for use with R or Python, instructors can also use Excel. Students learn how to address important data and model specification issues, including outliers, autocorrelation, and inflation. Students are excited to acquire relevant tools and skills they can apply to future work projects.
Data Analytics, Netlike Knowledge Structure, and Academic Performance
Authors: Choo Freddie , Tan Kim
Published: October 2023

The first objective of this study was to investigate whether data analytics could form a netlike knowledge structure (NKS) of learned course materials in accounting. We tested a group of students that used data analytics to solve an asset misappropriation case study and a control group that did not. We found evidence that data analytics has formed such a structure. The second objective was to investigate whether NKS was associated with academic performance. We conducted regression analyses on the NKSs and test scores. We found evidence that NKS with high connectivity and processing efficiency was associated with better accounting test scores. Overall, the findings imply that integrating data analytics into accounting courses benefits the learning of course materials by forming an NKS positively associated with academic performance. This study makes several contributions, including extending the work on NKS conducted predominantly in the cognitive science domain to the accounting domain.
Updated Theory and New Evidence on the Effect of Information System Precision on Managerial Reporting
Authors: Douthit Jeremy , Majerczyk Michael , McLuckie Thain Lisa
Published: October 2023

Information asymmetry is fundamental to participative budgeting. Hannan, Rankin, and Towry (2006, “HRT”) develop a nuanced theory regarding the effect of information asymmetry on slack. The authors provide evidence that suggests increasing the precision of a superior’s information system, thereby reducing information asymmetry, can increase slack. We develop a refined version of HRT’s theory by incorporating evidence of how nonpecuniary incentives affect subordinates’ reporting slack from research subsequent to HRT. Our updated theory predicts that slack decreases as information system precision increases, opposite to the results in HRT. To test our refined theory, we replicate HRT’s experiment and find results consistent with our theory. Our results support HRT’s general theory but highlight the importance of establishing regularities of how nonpecuniary incentives affect behavior in accounting. Specifically, our updated theory and new evidence suggest that improving information system precision decreases budgetary slack, contrary to the results suggested in HRT.
