Social Media and Fear of Missing Out: An Exploration of the
Role of Mindfulness, Cognitive Biases and Need to Belong in
Chinese College Students
Authors: Li Jing , Liu Sijia 
Published: November 2023

Background:
Fear of Missing Out (FoMO) on social media has emerged as
a significant concern, particularly among college students, with implications for mental
well-being and internet use. While previous studies have explored various aspects of
mindfulness about digital behaviors, the specific link between mindfulness and FoMO,
as well as the potential mechanisms involved, remains underexplored.

Objective:
Guided by the Conservation of Resources (COR) theory and the
Interaction of Person-Affect-Cognition-Execution (I-PACE) model, this study
investigates the relationship between mindfulness and FoMO among Chinese college
students. Additionally, it explores the mediating roles of cognitive bias and the need
to belong in understanding how mindfulness influences FoMO.

Methods:
Data was collected from 748 university students from two universities in
China. Participants completed questionnaires assessing mindfulness, cognitive bias, the
need to belong, and FoMO. Statistical analyses, including mediation models and
bootstrapping, were conducted using SPSS 25.0 and the PROCESS macro version 3.3.

Results:
The SPSS PROCESS macro Model 4 analysis revealed that the relationships
between mindfulness and FoMO (β=-.011, p=.738) and between Attention to Positive
Information (API) and FoMO (β=.029, p=.383) were nonsignificant. Mindfulness
exhibited negative associations with Attention to Negative Information (ANI) (β=-
.250, p<.001) and the need to belong (β=-.254, p<.001) and positive associations with
API (β=.268, p<.001). Furthermore, ANI positively correlated with FoMO (β=.182,
p<.001), and the need to belong had a significant positive impact on FoMO (β=.503,
p<.001). The mediation analysis indicated that the effect of mindfulness on FoMO
was fully mediated by ANI and the need to belong, with no direct effect through API.

Conclusion:
By recognizing mindfulness as a valuable psychological resource, this
research offers insights for developing targeted interventions aimed at reducing
FoMO and promoting healthier social media engagement among this population.
These findings contribute to the broader understanding of the interplay between
mindfulness, cognitive processes, motivation, and FoMO, offering guidance for
future research and practical interventions.
Simultaneous Determination of Two Metabolites of Gelsemium elegans by
LC-MS/MS in Rat Urine and its Application to Pharmacokinetic Study
Authors: Yan Rui , Zhang Shan 
Published: November 2023

Background:
G. elegans is a highly useful medicinal plant with broad and superior
clinical pharmacological effects. However, it also exhibits high toxicity to humans, so it must be
used with extreme caution in clinical practice. Previous studies on G. elegans have mainly focused on its main ingredients from perspectives of pharmaceutical analysis, pharmacokinetics,
and pharmacodynamics. The kinetic behavior of G. elegans' main metabolites in vivo has not yet
been reported, which is also crucial for studying the herb's toxification and detoxification process.

Aims:
This study aimed to establish a quantitative method to describe the metabolic profile of
the two main metabolites of koumine after oral administration of G. elegans to rats.

Objective:
The objective of this study was to test two major metabolites of G. elegans in rat urine
after administration using a rapid and sensitive high-performance liquid chromatographic-tandem mass spectrometric (HPLC-MS/MS) method developed in advance.

Methods:
A Kromasil C18 column was used as the stationary phase for chromatographic separation, with an isocratic mobile phase consisting of mixture of water (2 mM ammonium formate),
formic acid, and methanol (25:0.05:75, v/v/v) at a flow rate of 0.40 mL/min. The mass spectrometer was equipped with an electrospray ionization (ESI) source operating in positive ionization
mode, and detection was performed using a selective reaction monitoring (SRM) mode. Detection was performed in selective reaction monitoring (SRM) mode. Protein precipitation was used
to pretreat the rat urine samples before analysis, with acetonitrile as the precipitation solvent. In
this study, a "relative quantification" strategy was employed, which avoided the expensive and
time-consuming separation of standard substances. The assay was validated in terms of specificity, linearity, precision, stability, recovery, and other aspects.

Results:
The intra- and inter-day precision values were less than 12.7%. The recoveries at three
different concentrations were all above 73.1%. The stability study showed that the analytes were
stable during the experiment. The method was then used to study the kinetic profiles of N-demethylkoumine and N-oxidatekoumine in rat urine for the first time.

Conclusion:
In this study, the established LC/MS method was fully validated and proven to be
sensitive and accurate for the simultaneous determination of the two main metabolites of G. elegans in rats' urine samples. These results could provide references for the safe use of koumine
and G. elegans in clinical applications.

Authors: Valla Lisbeth , Haga Silje Marie , Garthus-Niegel Susan , Drozd Filip 
Published: November 2023

Abstract

Background
The perinatal period is a vulnerable time when women are at increased risk of depression. “Mamma Mia” is a universal preventive internet-delivered intervention offered to pregnant women, with the primary goals of preventing the onset or worsening of depression and enhancing subjective well-being during the perinatal period. However, treatment dropout from internet-delivered interventions is often reported.

Objective
The study aim was to acquire an understanding of the different experiences among participants who dropped out of the Mamma Mia intervention during pregnancy, compared to participants who dropped out during the postpartum follow-up phase.

Methods
A total of 16 women from a larger randomized controlled trial (Mamma Mia) participated in individual semistructured interviews following a strengths, weaknesses, opportunities, and threats format. Of the 16 participants included, 8 (50%) women dropped out early from the intervention during pregnancy (pregnancy group), whereas 8 (50%) women dropped out later, after giving birth (postpartum follow-up group). Data were analyzed using the framework approach.

Results
The results showed that there were differences between the groups. In general, more participants in the postpartum follow-up group reported that the program was user-friendly. They became more aware of their own thoughts and feelings and perceived that the program had provided them with more new knowledge and practical information than participants in the pregnancy group. Participants in both groups suggested several opportunities for improving the program.

Conclusions
There were differences between women who dropped out of the intervention during pregnancy and the postpartum follow-up phase. The reported differences between groups should be further examined.

Published: November 2023

Objectives: Hepatic encephalopathy (HE) is a common and prognostic complication of cirrhosis. It may reflect either a reversible metabolic encephalopathy, brain atrophy, edema or any combination of these conditions. The mechanisms causing brain dysfunction in liver failure are still unknown. Ammonia is the best-characterized neurotoxin that precipitates HE. The purpose of this study was to ascertain the role of ammonia in HE. Methods: A hospital-based prospective study on HE was carried out at the First Central Hospital of Mongolia and the Chingeltei-Uul District Hospital in 2011-2013. Patients with hepatic failure were subdivided into the three following groups: (1) patients without HE, (2) patients with grade l-ll HE, (3) patients with grade lll-IV HE. We took liver function tests, Model for End-Stage Liver Disease (MELD) score and blood ammonia and correlated them with the severity of encephalopathy. The mean variables ±SD, p-values, and Pearson coefficients were calculated by SPSS 17.0. Results: The total sample size was 120 and the mean age was 36.8 ±15.4 years. Elevated ammonia level was observed in every stage of HE and increased by stage (p< 0.0001) MELD score and elevated ammonia level had a strong positive correlation (r = 0.54, p = 0.0001). In patients with any infection, the ammonia level was higher (p< 0.0001) than other groups. Conclusion: Ammonia is one of the diagnostic biomarkers of HE.

Published: November 2023

The work-life balance has become an important issue in the fast-paced and demanding work environment today. This study aims to analyze the determinants and consequences of work-life balance by examining the influence of working hours and job burnout on employee well-being, with the work-life balance as a mediating variable. It involved 100 active employees from the Local Government-Owned Water Utility of Pontianak City, chosen through a purposive sampling method. The data was collected using a questionnaire and analyzed using Structural Equation Modeling – Partial Least Square (SEM - PLS). The results reveal that the job burnout has a significant effect on both the work-life balance and employee well-being. However, the working hours does not have a significant effect on both the work-life balance and employee well-being. Additionally, the work-life balance has a significant effect on the employee well-being. Furthermore, this study confirms that the work-life balance is able to mediate the effect of job burnout on the employee well-being, but it is not able to mediate the effect of working hours on the employee well-being. These results provide managers and HR practitioners with insights into how to improve the employee well-being through effective working hours plans, job burnout reduction, and work-life balance programs.JEL: I31, I39.

Published: November 2023

Точность описания термодинамических процессов, протекающих в дисперсных средах внутри сосудов или труб, повышается при учете термодинамического взаимодействия дисперсных частиц и стенок сосуда. В статье рассмотрена расположенная вблизи плоской стенки сферическая частица, не имещая внутренних источников тепла, но искажающая распределение температуры в среде за счет разницы теплопроводностей (своей и среды). При этом оказывается удобным зеркально продолжить содержащее частицу полупространство и заменить исходную систему «плоскость + частица» другой - «две симметричные частицы». Для решения стационарного уравнения теплопроводности в полученном безграничном пространстве применяется метод мультипольных разложений; структура коэффициентов перед мультиполями определяется симметрией конфигурации частиц и граничных условий задачи. В работе также обсуждается возможность предельного перехода от системы «сфера большого радиуса + малая сфера» к системе «плоскость + частица» для решения исходной задачи в полупространстве.
Description of thermodynamic processes in disperse media placed in containers and tubes becomes more precise if thermodynamic interaction of disperse particles and container walls is taken into account. The paper deals with spherical particle without internal heat sources. This particle is placed near a plane wall and distorts temperature distribution in a medium because of difference in heat conduction coefficients. Authors obtain that it is convenient to use reflection and continue the half-space bounded by the wall, thus replacing system ``plane + sphere'' by another one: ``two symmetric spheres''. To solve Laplace equation in unbounded space authors use multipole expansion; structure of coefficients in this expansion depends on symmetry of particles' configuration and of boundary conditions. The paper also discusses possibility of limit transition from system ``a large sphere + a small sphere'' to system ``plane + sphere'' in order to solve a problem about a spherical particle in a half-space.

Published: November 2023

The world-wide COVID-19 pandemic situation has had a significant impact on the everyday work of organizations, including private educational institutions. In the proposed study, the authors focus on how a private school providing pre-primary, primary, and secondary education has faced the biggest challenges of these times - 1) in compliance with its mission, to provide children and youth with high quality education regardless the circumstances; 2) to take advantage of the situation, i.e. to find the best possible alternatives and so, be one step ahead of its competitors; and 3) as being partially dependent on school fees, not to lose paying customers. After a thorough consideration of alternatives, the school – as one of few in Slovakia – opted for offering the whole educational program online only several days after all schools were closed in the country.
The purpose of the study is to provide an example of good practice for other – not only woman-owned – organizations and to support the real efficiency of the applied approach by relevant data. The authors of the study carried out a questionnaire survey with the school’s students, the students’ parents, and the whole teaching staff, focusing on their overall satisfaction with the realized online education, their experiences and opinions, as well as their attitudes towards e-learning in secondary schools in general. The questionnaire survey was a part of a larger research focusing on distance learning strategies applied during school closures in Slovakia. In the study, topic relevant research findings are presented, which indicate that the pandemics has not had a negative impact on this particular educational institution and this woman-owned business has even found new opportunities for its future work.

Authors: Redd Tammi C , Wu Sibin 
Published: November 2023

Social Networks have always been an invaluable resource for entrepreneurs attempting to engage in venture creation and growth. While differences in gender and its effect on traditional social networks have been explored, it is worth examining the gender effect when using the internet to create online network connections that supply useful resources. This study investigates the difference between male and female entrepreneurs’ social networks, the resources obtained from those networks, and the evolution of the ever-valuable weak tie. Hypotheses are tested using analysis of variance and analyses reveal women that female entrepreneurs and male entrepreneurs use the online network connections very differently in terms of the type of relationship and the type of resource acquired. The findings create implications for organizations that support female, minority or disadvantaged business development as these ventures increase in number and success.
Copper-Zinc Superoxide Dismutase (CuZn-SOD) Electrochemical Catalytic Amplification Sensing at Pt Ultramicroelectrodes
Authors: Sánchez-Álvarez Annelis O. , Melendez J. Andres , Silvestry-Ramos Mariena , Cabrera Carlos R. 
Published: November 2023

Abstract. Copper/zinc superoxide dismutase (CuZnSOD), a 32.5 kDa metalloprotein with a radius of ca. 2.1 nm, catalyses the superoxide to hydrogen peroxide and molecular oxygen. At the femtomolar concentration range, has been sensed through electrochemical catalytic amplification using a Pt ultramicroelectrode. During amperometric (i vs. t) analysis, cathodic and anodic current transitions peaks were seen, in agreement with the metalloprotein catalytic mechanism. The current amplitudes were analyzed and correspond to the CuZnSOD dimensions. Thermal treatment of metalloprotein samples at 80 °C showed larger current spikes suggesting aggregation without losing its catalytic capability. The size was confirmed by transmission electron microscopy.

Resumen. Cuprozinc superóxido dismutasa (CuZnSOD), es una metaloproteina de 32.5 kDa con un radio de aproximadamente 2.1 nm. Esta enzima cataliza la reacción de superóxido a peróxido y oxígeno molecular. Por primera vez, esta proteína es detectada a concentraciones femtomolares haciendo uso de la técnica electroquímica conocida como amplificación catalítica y la tecnología de ultra-microelectrodos de Pt. Durante un análisis amperométrico (curvas i vs. t), se observaron picos transitorios de corriente catódica y anódica que concuerdan con el mecanismo catalítico de la enzima. Al analizar la amplitud de la corriente, la misma concuerda con las dimensiones de CuZnSOD. Luego de exponer la proteína a un tratamiento térmico de 80 °C, CuZnSOD mostró picos de corriente transitorias que sugieren aglomeración de la enzima sin perder su capacidad catalítica. El tamaño fue confirmado por microscopía electrónica de transmisión.

Published: November 2023

Abstract. Dyes are widely used in many industrial operations for a variety of products; however, when wastewater is discharged without a treatment in rivers and lakes, severe environmental impacts are observed. In this work, the results of a solar wastewater treatment are presented. The solar treatment consists in parabolic heater coupled with a solar distiller which contains a ZnO plate that works as photocatalyst. Distilled water presents good characteristics; nevertheless, a residue that contains dye and intermediate products is also obtained. An electrooxidation treatment using boron-doped diamond electrodes (BDD), is applied at the residue as a polishing step. It was observed that wastewater quality improves when using an aqueous solution of pH 2.7 and a current density of 22.2 mA cm-2. Physicochemical test such as COD, and UV-Vis were used to evaluate the wastewater quality. It was found that 40 minutes are required to attain the improvement. This technology is environmental friendly since low energy is required (5 kW h L-1).

Resumen. Los colorantes son ampliamente utilizados en la industria para una gran variedad de productos; cuando se descargan aguas residuales con dichos compuestos en ríos o lagos, ocasionan severas afectaciones al medio ambiente. Este trabajo presenta los resultados obtenidos al someter agua sintética a un proceso consistente en un calentador acoplado a un destilador solar que contiene un fotocatalizador. En dicho procedimiento se obtiene agua destilada de buena calidad, sin embargo, también se genera un agua residual concentrada con presencia de colorante y productos intermediarios. A manera de pulimento se aplica la electrooxidación empleando electrodos de diamante dopados con boro. Con las mejores condiciones: pH 2.7 y densidad de corriente de 22.2 mA cm-2, se encuentra que el agua residual presenta una notable mejoría en características fisicoquímicas de DQO y espectroscopia UV-Vis. Se encontró que es necesario un periodo de tiempo de 40 minutos para mejorar las características del agua concentrada, lo cual hace que este proceso sea ambientalmente amigable, ya que requiere la aplicación de poca energía (5kW h L-1).

Published: November 2023

Abstract. In the present research work, the corrosion inhibition capacity of a liquid extract based on Citrus X-Latifolia leaves was evaluated as a green inhibitor that complies with a natural, economical, and environmentally friendly option. The tests were carried out on a carbon steel AISI 1045 exposed to an acid corrosive medium of 10 mL H2SO4 (0.5 M) to which various concentrations of the extract were dosed as follows: 40, 80, 120, 160, 200, 240, 280, 320, 360 and 400 ppm under standard conditions. Characterization by FT-IR was carried out to detect functional groups of the extract. The inhibitory behavior was recorded by electrochemical techniques (Tafel polarization and EIS). Finally, optical microscopy was used to evaluate the corrosion morphology. The results reveal that the adsorption of the extract molecules on steel follows the behavior of a Langmuir isotherm, reaching a maximum efficiency of 89 % with a concentration of 400 ppm. Finally, an evident change in the surface morphology of the steel sample is observed, thus reducing the pitting corrosion attack on AISI 1045 steel.

Resumen.
