Age variation among U.S adults in social media experiences and beliefs about who is responsible for reducing health-related falsehoods (Preprint)
Authors: Galinkala Prathyusha , Atkinson Elise , Campos-Castillo Celeste
Published: February 2024

BACKGROUND

What is already known on this topic: Adults aged 65 and older are less likely to identify health related falsehood on social media than their younger counterparts. While policies and interventions exist to reduce the presence and impact of falsehoods, few consider the perspectives of those aged 65 and older.
What this study adds: We found adults 65 and older were more likely than their younger counterparts to believe medical providers should be responsible for reducing falsehoods.
How this study might affect research, practice or policy: Medical providers should consider discussing the health-related information that their patients who are 65 and older find on social media, but time during the clinic visit may be limited. Additional interventions should be designed and evaluated to aid in identifying and discrediting falsehoods, such as mobile apps.

OBJECTIVE

Despite growing concern over older adult’s exposure to false health information on social media, little research examines their beliefs over how to address the problem. The current study examines how the age of U.S. adults is associated with their reported experiences with health-related falsehoods on social media and their beliefs about who should be tasked with reducing such falsehoods.

METHODS

A secondary analysis of the 2022 HINTS data, a nationally representative survey of U.S. adults (18 and older). Multivariable logistic regressions estimated how respondents’ age is associated with their self-reported social media usage, difficulty to detect health-related falsehoods on social media, discussion of health information found on social media with medical providers, and their beliefs regarding who should reduce health-related falsehoods on social media. Regression estimates were adjusted for respondents’ sociodemographic and health characteristics.

RESULTS

Daily social media use decreased with respondents’ age. Respondents aged 50-64 and 65-74 were more likely than respondents aged 18-34, 35-49, and 75+ to self-report they “strongly agree” it is difficult for them to detect health-related falsehoods on social media. Compared to younger adults, older adults (65 and older) were more likely to believe medical providers should be responsible for reducing online falsehoods.

CONCLUSIONS

In addition to ongoing efforts by social media platforms to detect and remove falsehoods, the findings suggest medical providers should be tasked with discrediting health-related falsehoods on social media for older adults. However, time during the clinical visit is limited. Future research is needed to discover new approaches and tools tailored to older adults to assist with filtering and discrediting health-related falsehoods on social media.

Published: February 2024

UNSTRUCTURED

Advancements in mobile health technologies and machine learning approaches have expanded the framework of behavioral phenotypes in obesity treatment to explore the dynamics of temporal changes. This study aimed to investigate the dynamics of behavioral changes during obesity intervention and identify behavioral phenotypes associated with weight change using a hybrid machine learning approach. In total, 88 children and adolescents (ages 8-16 years; 62/88, 71% male) with age- and sex-specific BMI ≥85th percentile participated in the study. Behavioral phenotypes were identified using a hybrid 2-stage procedure based on the temporal dynamics of adherence to the 5 behavioral goals during the intervention. Functional principal component analysis was used to determine behavioral phenotypes by extracting principal component factors from the functional data of each participant. Elastic net regression was used to investigate the association between behavioral phenotypes and weight change. Functional principal component analysis identified 2 distinctive behavioral phenotypes, which were named the high or low adherence level and late or early behavior change. The first phenotype explained 47% to 69% of each factor, whereas the second phenotype explained 11% to 17% of the total behavioral dynamics. High or low adherence level was associated with weight change for adherence to screen time (β=−.0766, 95% CI −.1245 to −.0312), fruit and vegetable intake (β=.1770, 95% CI .0642-.2561), exercise (β=−.0711, 95% CI −.0892 to −.0363), drinking water (β=−.0203, 95% CI −.0218 to −.0123), and sleep duration. Late or early behavioral changes were significantly associated with weight loss for changes in screen time (β=.0440, 95% CI .0186-.0550), fruit and vegetable intake (β=−.1177, 95% CI −.1441 to −.0680), and sleep duration (β=−.0991, 95% CI −.1254 to −.0597) Overall level of adherence, or the high or low adherence level, and a gradual improvement or deterioration in health-related behaviors, or the late or early behavior change, were differently associated with weight loss for distinctive obesity-related lifestyle behaviors. A large proportion of health-related behaviors remained stable throughout the intervention, which indicates that health care professionals should closely monitor changes made during the early stages of the intervention.

Technical and Economic Assessment of the Integration of Refrigeration Concepts into the Proceeding Extension of Solar Energy Systems in Brazil
Authors: Wiencke Christopher , Ávila Giovani , Biek Katja
Published: February 2024

Electricity is the main source used in the refrigeration process of environments and machines. Global warming and the expansion of the tropical belt increase the demand for refrigeration. The use of so-lar-assisted air conditioning has a great potential, especially in sub-tropical regions with high solar radiation contributing to demand´s fulfillment and reducing electricity from non-renewable sources. It has cooling potential in buildings reducing electricity´s peak demand, ecological footprint reducing carbon emissions and building´s ther-mal load using ecological refrigerants. Also benefits the urban mi-croclimate absorbing solar irradiation into the rooftop. The objective of this article is to survey the factors that influence the selection of components for a solar-assisted cooling system in buildings under different climatic conditions using an exploratory methodology based on the bibliography and on a survey of the state of the art describing the fundamental aspects and components of this technology, its func-tion, and benefits. Non-thermally driven applications were also con-sidered, such as conventional steam compression chiller, driven by electricity and compression cycle by photovoltaic energy. Different cooling systems at full load are compared. The research was applied in a school building in the city of Rio de Janeiro, concluding that so-lar-assisted refrigeration is an energetic and environmentally com-petitive alternative compared to compressors powered by electricity in conventional refrigeration systems.
Transculturalism in the Diasporic Writings of Bharati Mukherjee: A Note on The Tiger’s Daughter and Wife
Authors: Huidrom Dr. Sumitra , Nizam Saleha
Published: February 2024

This paper is an attempt to analyse the transcultural elements in the novels The Tiger’s Daughter and Wife written by Bharati Mukherjee, an Indian diasporic writer. Mukherjee’s writings reflect her own life as an immigrant, as she writes about the pain of adjusting to a completely alien land with its own culture and beliefs. Through her stories, the readers are able to catch a glimpse of the immigrant life, and their conflict between location and culture. An attempt is made to explore the concept of transculturalism in her novels by tracing the respective journeys of the protagonists, Tara and Dimple, with the help of Homi Bhabha’s concepts of mimicry, third space and hybridity.

A comparative study of frames and narratives identified within scientific press releases on ocean climate change and ocean plastic
Authors: Vonk Aike N. , Bos Mark , Smeets Ionica , van Sebille Erik
Published: February 2024

To understand how scientific institutions communicate about ocean climate change and ocean plastic research, 323 press releases published between 2017 and 2022 were analyzed. A clustering method revealed 4 ocean climate change- and 5 ocean plastic frames that were analyzed qualitatively. Ocean plastic was presented as a biological and health issue, placing an emphasis on solutions and society's obligation to implement them. Ocean climate change was framed as environmental and socio-economic problem, highlighting politics' responsibility for mitigation. Narratives were only used to personify science and represent scientists, indicating that future press releases could include more social dimensions to engage audiences in ocean issues.
Coherence and contextuality in a Mach-Zehnder interferometer
Authors: Wagner Rafael , Camillini Anita , Galvão Ernesto F.
Published: February 2024

We analyse nonclassical resources in interference phenomena using generalized noncontextuality inequalities and basis-independent coherence witnesses. We use recently proposed inequalities that witness both resources within the same framework. We also propose, in view of previous contextual advantage results, a systematic way of applying these tools to characterize advantage provided by coherence and contextuality in quantum information protocols. We instantiate this methodology for the task of quantum interrogation, famously introduced by the paradigmatic bomb-testing interferometric experiment, showing contextual quantum advantage for such a task.

Published: February 2024

This research aims to explore the influence of the family affects the behavior of children who carry out acts of terror and what efforts can be made to prevent children from becoming perpetrators caused by family factors in Bulukumba Regency, Indonesia. The research methods used is empirical research using a phenomenological approach. The results of this study indicate that the main factor in criminal behavior and causes of crimes committed by children is the dysfunction of parent roles in terms of supervising and guiding their children, accompanied by an inharmonious relationship between parents and children. For example, when parents are too busy working, they tend to have less communication with their children, so children spend more time outside the home and choose the wrong social environment. In addition, factors such as a lack of children's education and people who do not care about the surrounding environment can also be causes of child crime. Actions that must be taken to overcome the form of arc terror crimes committed by children lie in the ways of educating children, which are implemented by families, parents, and the community, such as religious leaders and community leaders.
FAILURE OF CRIMINAL LAW IN RECOVERING STATE LOSSES DUE TO CRIMINAL ACTS OF CORRUPTION
Authors: Rahman Amar Muammar , Husnul Muhammad
Published: February 2024

Effectiveness Returning state financial losses due to criminal acts of corruption is still far from expectations. In 2022, the number of decisions observed by ICW will increase fundamentally, namely 2,056 decisions with 2,249 defendants. In 2022, the average perpetrator of corruption will be imprisoned for 3 years and 4 months, which will cost the state Rp. 48,786,368,945,194.70 (Rp. 48,786 trillion). This article aims to describe the form of failure of Indonesian criminal law in efforts to return state assets and analyse the causes and consequences resulting from the failure of criminal law in efforts to return state assets. This research is based on qualitative research by conducting legislative studies and literature studies. The research results show that the form of failure to recover state financial losses is characterized by the increasing value of unrecovered state losses from year to year. This is a result of the legal vacuum that can be applied in efforts to recover state financial losses because the applicable legal formulation is no longer relevant or cannot reach the scope for confiscation of corruptors' assets so that judges have limitations in making sentences regarding the return of state losses. This has the impact of hampering equitable economic development and hindering foreign investors because the rulers and conglomerates use land to benefit certain groups. This research concludes that the formulation of criminal law cannot accommodate legal needs regarding the recovery of state financial losses due to corruption, so it is recommended to immediately pass the Asset Confiscation Bill.

Published: February 2024

El presente artículo tuvo como finalidad explicar la incorporación de la planificación estratégica orientada a objetivos en el gobierno de las universidades estatales chilenas, atendiendo al rol desempeñado por el nicho de experimentación estudiado, el régimen de capitalismo académico dominante y un paisaje de economía política con un elevado grado de privatización. Para ello, la investigación utilizó la perspectiva multinivel de las transiciones sociotécnicas asociada a un estudio de caso y siguió una metodología cualitativa que incluyó la realización de diversas entrevistas a actores claves, como también una revisión documental de la gestión universitaria de los últimos treinta años. Los resultados del estudio demostraron que la adopción de una innovación transformativa como la planificación estratégica en la Universidad de Talca implicó un proceso de cambio profundo y significativo en el gobierno interno de la Institución. La innovación alternativa (modelo de gestión estratégica y planificación) es capaz de permear el régimen establecido desarrollando prácticas (permanentes y autogestionadas), creando una cultura de la calidad y de la innovación, estableciendo una disciplina financiera y vinculando a la institución con las partes interesadas (sociedad, Estado, sector privado y academia), transformándose en una institución universitaria señera para el resto del sistema.

Authors: Rios Díaz Alba Milena , Romero Díaz Carmen Helena , Novikova Olga A. , Zapata-Molina César , Castaño Giraldo Nelson Eduardo
Published: February 2024

El aprendizaje compartido es un enfoque didáctico que se basa en la idea que los estudiantes aprenden más cuando están colaborativamente con otros actores como sus compañeros, maestros y padres de familia apoyados por artefactos epistémicos adecuados (tecnologías analógicas y digitales) que conforman un contexto de aprendizaje favorable. El objetivo del artículo fue analizar la didáctica del aprendizaje compartido como una manera de mejorar la eficiencia del proceso educativo en la enseñanza-aprendizaje del inglés como lengua extranjera. El estudio se basó en una investigación cualitativa con la primera fase de análisis bibliométrico que utiliza la técnica citation pearl growing. La segunda fase se apoyó en la hermenéutica, con la técnica del análisis textual de documentos escritos. El análisis bibliométrico utilizó una ecuación de búsqueda ingresada al indexador Scopus. Se hizo un estudio de coocurrencia de términos con el software VOSviewer® y se analizó el contenido de 435 artículos en el software ATLAS.ti®. Los siete clústeres que emergieron fueron reagrupados contextualmente en dos categorías principales según el nivel de coocurrencia: aprendizaje colaborativo y aprendizaje cooperativo. Los hallazgos representaron un valor de conocimiento sobre los métodos didácticos que deben reforzarse para garantizar la eficiencia del proceso de enseñanza-aprendizaje del idioma inglés en la educación básica y media. También se ha constatado que, a nivel mundial, el aprendizaje compartido adquiere otras connotaciones que le agregan particularidades y que, igualmente, convergen en la interacción de los actores involucrados en los procesos educativos, promoviendo la sana convivencia, el bienestar y la paz social en ambientes escolares.
Numerical Investigation of Observational Flux Partitioning Methods for Water Vapor and Carbon Dioxide
Authors: Zahn Einara , Ghannam Khaled , Chamecki Marcelo , Moene Arnold F. , Kustas William P. , Good Stephen Paul , Bou-Zeid Elie
Published: February 2024

While yearly budgets of CO2 and evapotranspiration (ET) above forests
can be readily obtained from eddy-covariance measurements, the
quantification of their respective soil (respiration and evaporation)
and canopy (photosynthesis and transpiration) components remains an
elusive yet critical research objective. To this end, methods capable of
reliably partitioning the measured ET and F_c fluxes into their
respective soil and plant sources and sinks are highly valuable. In this
work, we investigate four partitioning methods (two new, and two
existing) that are based on analysis of conventional high frequency
eddy-covariance (EC) data. The physical validity of the assumptions of
all four methods, as well as their performance under different
scenarios, are tested with the aid of large eddy simulations, which are
used to replicate eddy-covariance field experiments. Our results
indicate that canopies with large, exposed soil patches increase the
mixing and correlation of scalars; this negatively impacts the
performance of the partitioning methods, all of which require some
degree of uncorrelatedness between CO2 and water vapor. In addition,
best performance for all partitioning methods were found when all four
flux components are non-negligible, and measurements are collected close
to the canopy top. Methods relying on the water-use efficiency (W)
perform better when W is known a priori, but are shown to be very
sensitive to uncertainties in this input variable especially when canopy
fluxes dominate. We conclude by showing how the correlation coefficient
between CO2 and water vapor can be used to infer the reliability of
different W parameterizations.
The impact of flap design on swelling, trismus, and pain after the lower third molar surgery: Buccal triangular flap vs. envelope flap
Authors: Matijevic Stevo , Djordjevic Filip , Vukasinovic Mila , Bukumiric Zoran , Dubovina Dejan
Published: February 2024

Background/Aim. Swelling, trismus, and pain (STP) are the most common complications that occur after the surgical extraction of impacted lower third molars (LTM). Buccal triangular and envelope flaps are the two most commonly used mucoperiosteal flaps in LTM surgery. The aim of this study was to compare the possible impact of these two types of flaps on the occurrence and intensity of postoperative STP after the surgical extraction of impacted LTMs. Methods. The study included 30 adult patients of both genders, with fully impacted LTMs in vertical position according to Winter classification and class I or II, and position A or B, according to Pell and Gregory classification. All patients were randomly divided into two groups depending on the type of the applied mucoperiosteal flap (triangular or envelope type). The degree of edema, interincisal distance (trismus), and the level of pain were evaluated preoperatively and at each follow-up (on the first, second, and seventh day postoperatively). Results. No statistically significant difference was found among the examined groups in terms of STP reduction in the postoperative period (p > 0.05). Conclusion. The choice of mucoperiosteal flap design, buccal triangular or envelope, during the surgical extraction of impacted LTMs has no impact on the intensity of postoperative STP.
Detecting the Cyber Attacks on IoT-Based Network Devices Using Machine Learning Algorithms
Authors: Calp M. Hanefi , Bütüner Resul
Published: February 2024

Today, the number and variety of cyber-attacks on all systems have increased with the widespread use of internet technology. Within these systems, Internet of Things (IoT)-based network devices are especially exposed to a lot of cyber-attacks and are vulnerable to these attacks. This adversely affects the operation of the devices in question, and the data is endangered due to security vulnerabilities. Therefore, in this study, a model that detects cyber-attacks to ensure security with machine learning (ML) algorithms were proposed by using the data obtained from the log records of an IoT-based system. For this, first, the dataset was created, and this dataset was preprocessed and prepared in accordance with the models. Then, Artificial Neural Network (ANN), Random Forest (RF), K-Nearest Neighbor (KNN), Naive Bayes (NB), and Logistic Regression (LR) algorithms were used to create the models. As a result, the best performance to detect cyber-attacks was obtained using the RF algorithm with a rate of 99.6%. Finally, the results obtained from all the models created were compared with other academic studies in the literature and it was seen that the proposed RF model produced very successful results compared to the others. Moreover, this study showed that RF was a promising method of attack detection.

Cryptographic methods today are a crucial tool for constructing information security systems. At the same time, to solve the problem of encrypting large amounts of information, block or stream symmetric ciphers are mainly preferred because of their efficiency and proven cryptographic strength, including against perspective quantum cryptanalysis. The effectiveness of modern symmetric ciphers largely depends on the cryptographic S-boxes applied in their construction, the quality of which largely determines the degree of implementation of the concepts of diffusion and confusion by the cryptographic algorithm, while the presence of large sets of cryptographically high-quality S-boxes is also important, in the terms of their application as a long-term key. Today, the Nyberg construction is well-known and widely applied in ciphers, including widespread AES block symmetric cipher. This construction allows you to synthesize high-quality S-boxes that harmoniously satisfy the main criteria for cryptographic quality, however, the set of S-boxes synthesized using this construction is small, which makes the task of developing new methods for synthesizing large sets of cryptographically high-quality S-boxes highly relevant. At the same time, as research shows, the constructions of extended Galois fields are a promising raw material for solving this problem. In this paper, the Galois field transform matrices of order N=256 are constructed for all isomorphic representations of the extended Galois field GF(256) which are analogous to the Reed-Muller transform but for the case of many-valued logic functions. As part of the research, the isomorphism invariant row numbers of the Galois field transform matrices are identified, which allows to obtain bijective S-boxes, as well as bijective S-boxes that correspond to the main criteria for cryptographic quality of component Boolean functions such as algebraic degree of nonlinearity, distance of nonlinearity, error propagation criterion, and criterion of minimization of correlation of output and input vectors of the S-box. At the same time, the cardinality of the set of synthesized S-boxes is ~23 times higher than the cardinality of the set of S-boxes of the Nyberg construction, which allows them to be used as a long-term key. The proposed S-boxes can become the basis for improving the effectiveness of existing symmetric cryptographic algorithms and developing new ciphers.
Is Climate Change Posing a Challenge to Food Security? Empirical Evidence from a Small Island Developing Country
Authors: Reddy Mahendra
Published: February 2024

Food security remains one of the main goals for all countries worldwide. While several agencies have mobilized resources to achieve this goal, food insecurity remains a significant livelihood challenge in many developing countries. Therefore, in this paper, we examine some critical factors affecting the food security of rural agricultural households in Fiji using the latest Agricultural Census data. This study reveals that farmers’ access to fishing grounds and non-timber forest resources can improve farming households’ food security. The study also shows that while the government vigorously pursues a transition from subsistence agriculture towards commercial agriculture, improving market access and reducing transportation costs will significantly improve food security. Given the importance of regular cash income, the study also demonstrates that off-farm employment of household members, particularly larger-sized households, will substantially help to improve food security. Lastly, and most importantly, the government must quickly examine how it could mitigate challenges posed by climate change, as this could devastate food security via reduced food production.

The present study aims to address the issue of monarchy by divine right in The Teachings of Neagoe Basarab to His Son Theodosius, which, due to its defining role in the most important work of the Romanian Middle Ages, allows one to observe how Saint Neagoe Basarab bases his teachings on references to the Holy Scriptures and to the Old Testament in particular. Furthermore, the chosen topic allows one to also understand the specific pillars of Slavic Byzantine Eastern theological culture which Neagoe Basarab highlights authentically and originally in his remarkable work.
Civil Procedure and Digital Technology: The Digitalization of the Judiciary and Civil Court Proceedings in the Czech Republic and Associated Problems
Authors: Šínová Renáta , Hamuľáková Klára
Published: February 2024

The article deals with the issue of digitalization of the judiciary and civil court proceedings. It clearly divides digitalization into institutional digitalization related to the judiciary as a whole and procedural digitalization, i.e., digitalisation within the framework of court proceedings. In its introduction, it focuses on institutional forms such as electronic systems and registers, in the second part it defines specific forms of digitalization within the current regulation of civil court proceedings, i.e., service via the public data network, electronic case management, recording of hearings, use of video-conferencing and finally also decision-making in the form of electronic payment orders. The paper highlights the problematic aspects of digitalization.
The Problem of Classification in Property Rights of Persons of the Same Sex in the Context of Private International Law
Authors: Tomešová Klára
Published: February 2024

In Czech private international law, the applicable law for property relations of spouses and registered partners is regulated differently. The rapid development in the legal regulation of same-sex marriages causes a division in the jurisdictions among the EU Member States as well as a non-uniform approach in the norms of private international law. Given that same-sex marriage is not legalized in the Czech Republic, a problem of classification arises in Czech private international law. The paper will focus on the question of classification of the property regime of same-sex couples who have entered into marriage in one of the states that admit such unions, and the solution to this problem of classification will be examined both at the national and EU levels.
Extended Lorenz majorization and frequencies of distances in an undirected network
Authors: Egghe Leo
Published: February 2024

Purpose

To contribute to the study of networks and graphs.

Design/methodology/approach

We apply standard mathematical thinking.

Findings

We show that the distance distribution in an undirected network Lorenz majorizes the one of a chain. As a consequence, the average and median distances in any such network are smaller than or equal to those of a chain.

Research limitations

We restricted our investigations to undirected, unweighted networks.

Practical implications

We are convinced that these results are useful in the study of small worlds and the so-called six degrees of separation property.

Originality/value

To the best of our knowledge our research contains new network results, especially those related to frequencies of distances.
Characterizing structure of cross-disciplinary impact of global disciplines: A perspective of the Hierarchy of Science
Authors: Liu Ruolan , Mao Jin , Li Gang , Cao Yujie
Published: February 2024

Purpose

Interdisciplinary fields have become the driving force of modern science and a significant source of scientific innovation. However, there is still a paucity of analysis about the essential characteristics of disciplines’ cross-disciplinary impact.

Design/methodology/approach

In this study, we define cross-disciplinary impact on one discipline as its impact to other disciplines, and refer to a three-dimensional framework of variety-balance-disparity to characterize the structure of cross-disciplinary impact. The variety of cross-disciplinary impact of the discipline was defined as the proportion of the high cross-disciplinary impact publications, and the balance and disparity of cross-disciplinary impact were measured as well. To demonstrate the cross-disciplinary impact of the disciplines in science, we chose Microsoft Academic Graph (MAG) as the data source, and investigated the relationship between disciplines’ cross-disciplinary impact and their positions in the Hierarchy of Science (HOS).

Findings

Analytical results show that there is a significant correlation between the ranking of cross-disciplinary impact and the HOS structure, and that the discipline exerts a greater cross-disciplinary impact on its neighboring disciplines. Several bibliometric features that measure the hardness of a discipline, including the number of references, the number of cited disciplines, the citation distribution, and the Price index have a significant positive effect on the variety of cross-disciplinary impact. The number of references, the number of cited disciplines, and the citation distribution have significant positive and negative effects on balance and disparity, respectively. It is concluded that the less hard the discipline, the greater the cross-disciplinary impact, the higher balance and the lower disparity of cross-disciplinary impact.

Research limitations

In the empirical analysis of HOS, we only included five broad disciplines. This study also has some biases caused by the data source and applied regression models.

Practical implications

This study contributes to the formulation of discipline-specific policies and promotes the growth of interdisciplinary research, as well as offering fresh insights for predicting the cross-disciplinary impact of disciplines.

Originality/value

This study provides a new perspective to properly understand the mechanisms of cross-disciplinary impact and disciplinary integration.

Published: February 2024

The frequency of forest fires has increased in recent years. This phenomenon has led to an increase in the difficulty of fighting them and an increase in the occupational exposure of firefighters. This study aims to carry out a systematic review protocol to obtain information on firefighters' occupational exposure on the fire front. A protocol was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: PRISMA Statement guidelines. There were no age, gender or publication date restrictions for including articles within the scope of firefighter samples. The study aimed to understand all the risks to which firefighters are exposed when fighting forest fires and their relationship with the onset of occupational diseases. Thus, all studies with laboratory or real-time monitoring, using samples of firefighters, and which carried out evaluations that made it possible to identify exposure risk factors and their relationship with occupational activity were included. This list makes it possible to verify all the studies carried out up to the date of the review on this subject and to guarantee a contribution to improving knowledge in this area of research.

Authors: Puspitowati Ida , Firdausy Carunia Mulya , Handoyo Sarwo Edy
Published: February 2024

Women's SMEs contribute to the economy, so attention to business performance is important to improve. Efforts to improve the performance of women SMEs require knowledge of the factors that play an important role in SME performance. This research was conducted on women SMEs in Belitung district by examining several factors that affect performance, namely social networks, family support and product innovation. In previous studies, there were differences in the results of several researchers on the influence of determining factors on performance, so this research will fill this gap as well as test the role of product innovation as a mediator of social networks and family support on business performance. By using the cross-section method, 113 women’s SMEs were obtained who have been running a business for a minimum of 1.5 years and are engaged in the processing industry.  Data analysis with Partial Least Square-Structural Equation Modeling (PLS-SEM), SmartPLS v.4.0 was used in data processing. The path coefficient results show that social network variables and product innovation have a positive and significations effect, while family support has no significations effect on SME performance. Product innovation partially mediates social networks towards women’s SMEs performance, while product innovation fully mediates family support on women’s SMEs performance. Family support has no significations effect towards women’s SMEs performance, this illustrates that women’s SMEs lack family support in their business activities.
FACTORS AFFECTING EARNINGS MANAGEMENT IN THE PLANTATION INDUSTRY IN INDONESIA DURING 2015-2019
Authors: Maginta Irianto , Lukman Hendro
Published: February 2024

The objective of this research is to obtain empirical evidence about the effect of profitability, leverage, firm size, and liquidity on earnings management on plantation companies listed on the Indonesia Stock Exchange (IDX) during the years of 2015-2019. This research uses secondary data. This research is conducted with a sample of 62 plantation company data with the technique used in this study is purposive sampling. The research data was processed using Statistical Product and Service Solution program for Windows version 26 (SPSS version 26). The results of this research show that the leverage and firm size have a positive and influence on earnings management practices, while profitability and liquidity have no effect on earnings management. The implication of this research is that companies must communicate intensively with shareholders so that this does not occur or can reduce information asymmetry in carrying out earnings management. By maintaining good communication with shareholders, and maintain profitability, proper leverage ratio and liquidity as well as optimizing assets to earn profit, it is believed that the financial report information issued by the company does not involve earnings management practices so that it becomes a positive signal for investors which can ultimately increase stock prices and company value.
