Effect of Voluntary Certifications on Non-Traditional Agro-Exports in Peru
Authors: Horna Arrieta Marialexandra , Mendoza Natividad Bertha Lucía
Published: January 2025

This paper analyzes the impact of voluntary private certifications, focusing on GlobalGAP, on the performance of non-traditional agroexports in Peru. The main objective is to determine whether holding these certifica­tions enhances the export value of Peruvian firms. The central hypothesis is that voluntary private certifications are positively correlated with a higher export value. The theoretical model examines the relationship between the determi­nants for obtaining the GlobalGAP certification and its benefits, assessing the percentage variation in the export value of companies in dollars. The analysis employs the propensity score matching (PSM) model and a diffe­rence-in-differences (DID) estimator to evaluate the effect on export value between certified and non-certified companies. The results show that while GlobalGAP certification positively contributes to export value, this effect does not extend to microenterprises. The paper provides new empirical evidence to the literature in Peru, offering data that can be used to design public policies. The findings support the promotion of certifications in the agro-export sector, fostering Peruvian agroexports in the international market and strengthening the competiti­veness of local agricultural activities.

Published: January 2025

In today’s business environment, talent management has become a crucial discipline for achieving sustainable competitive advantage. This study focuses on the talent acquisition and retention policies of Generation Z in Spanish family businesses, a significant sector in the country’s economy. Using a mixed approach of qualitative interviews and quantitative surveys, it explores the perceptions of managers and young employees on talent management policies. The results reveal that although many companies implement effective practices, there are significant differences in adapting to generational change. Factors such as fluid communication, continuous training and the inclusion of employees in strategic decision-making are key to the retention of young talent. In addition, job flexibility and a work environment that reflects the values of Generation Z are essential. This study contributes to both the theory and practice of human resource management, providing recommendations for improving the retention and satisfaction of young employees. Practical implications include the need for regular policy audits, the development of mentoring programs, and the implementation of regular satisfaction surveys to align with employee expectations.
SQSTM1/P62 Mediates the Effects of CPNE3 on the Epithelialmesenchymal Transition and Migratory Inhibition of Lung
Adenocarcinoma Cells
Authors: Li Yanping , Li You , Xu Liming , Yang Guangming , Zhou Huansi , Jin Mingjing , Yu Kai , Lu Chunhua
Published: January 2025

Introduction:

Copine-3 (CPNE3) is a conservative calcium-dependent phospholipid-binding protein belonging to the copines protein family. CPNE3 has been implicated in the development and progression of several diseases, including cancer

Method:

Herein, we investigated the molecular mechanisms through which CPNE3 regulates the migration of lung adenocarcinoma (LUAD) cells in vitro. Western blotting and
immunohistochemical assays showed that CPNE3 is widely distributed in LUAD tissues
and cell lines and that CPNE3 downregulation promotes the migration of human LUAD
A549 cells.

Results:

Stable isotope labelling with amino acids in cell culture, which is a quantitative
proteomics approach coupled with bioinformatic analyses, revealed that CPNE3 regulates SQSTM1/p62 and vimentin expression, indicating that CPNE3 may mediate epithelial-mesenchymal transition (EMT). CPNE3 silencing by siRNA upregulated vimentin
levels but downregulated E-cadherin levels in the A549 cells.

Conclusion:

Furthermore, SQSTM1/p62 knockdown enhanced migratory ability and
EMT progression in CPNE3-silenced A549 cells. Overall, CPNE3 knockdown was
found to promote EMT by inhibiting SQSTM1/p62 signalling and facilitating cell migration. Our findings highlight the role of CPNE3 as a tumour suppressor, providing deeper
insights into its carcinogenic roles in LUAD.

conclusion:

Overall, CPNE3 knockdown was found to promote EMT by inhibiting SQSTM1/p62 signalling and facilitating cell migration.

other:

Our findings highlight the role of CPNE3 as a tumour suppressor, providing deeper insights into its carcinogenic roles in LUAD.

with or without Suicide Attempts
Authors: Deng Wei-Xi , Liu Xiao-Bo , Guo Tian , Shang Li-Fei , Li Yi , Zeng Kuan , Long Jing-Yi
Published: January 2025

Background:

The incidence of Major Depressive Disorder (MDD) is high among adolescent
females, and MDD is often accompanied by suicide attempts (SAs), which have a serious negative
impact on health. However, changes in lipids, thyroid hormone, and brain metabolism among
female adolescents with MDD and the relationships between these three markers and MDD with SA
have yet to be elucidated.

Methods:

This study enrolled 71 MDD patients with SA (MDD+SA), 66 MDD patients without SA
(MDD-SA), and 47 healthy controls (HCs). We analysed the lipid and thyroid hormone levels and
magnetic resonance spectroscopy results of the subjects.

Results:

Low levels of social support, high levels of life stress, and high levels of suicidal ideation
(SI) were risk factors for SA. In MDD patients, 1) thyroid stimulating hormone was positively correlated
with triglyceride (TG) and N-acetyl aspartic acid (NAA)/creatinine in the prefrontal cortex
(PFC) and negatively correlated with high-density lipoprotein and the choline/creatinine in the thalamus;
2) free thyroxine was negatively correlated with the choline/creatinine in the thalamus; 3) total
cholesterol, TG, low-density lipoprotein, and choline/NAA in the PFC were positively correlated
with the severity of SI and suicide risk; and 4) NAA/creatinine in the thalamus was negatively correlated
with the severity of SI and suicide risk.

Conclusion:

In female adolescents with MDD, there are significant synergistic changes in lipids, thyroid
hormones, and brain metabolism-related factors, and the changes in these indicators may be related
to the pathological mechanism of SA.

Producción de protector solar a partir de Chlorella vulgaris
Authors: Sandoval Herrera Juan , Casas Laura , Naranjo Kelly
Published: January 2025

Microalgae are potential candidates for the development of safe and environmentally friendly photoprotectors since they can produce metabolites rich in UV filter (β carotenoids and myco-porins) because they are found in ecological niches that allow them to develop pigments to capture light. In this work, Chlorella vulgaris was implemented in the production of a laboratory-scale sunscreen. This was grown in two photobioreactors in the medium of Bold Basal cultivation for 42 days, with continuous pneumatic agitation, pH between 8-9 and temperature between 17 °C and 19 °C. The light intensity supply was continuous and of red LED light and white LED light type for the first crop and the second crop, respectively. Cell growth, growth rate, dry weight, productivity and concentration of β carotenoids and mycosporins were evaluated. For the formulation of sunscreen, dry microalgal biomass was used as a UV filter and the prototype was evaluated with its physical, organoleptic properties and sun protection factor through in vitro method. White LED light increased the growth rate and productivity of the microalgae. The concentration of mycosporins increased in the first culture and the concentration of β carotenoids was affected by the intensity of light, showing higher light intensity, greater production of these photoprotective molecules. The SPF was 7.74 which classifies the sunscreen as a medium protection. The results obtained in this work demonstrate the potential of Chlorella vulgaris to be used in the production of biological sunscreens.

The access and use of bibliographic information from scientific activity in Colombian territories is of vital importance to know the impact, productivity, collaboration and evolution of regional and national research. However, this information is presented in a static and unstructured manner in the official national platforms available for this purpose, thus limiting its analysis for the strategic decision making by the actors in the science, technology and innovation environment. This research proposes a tool for extracting, structuring and persisting data registered by researchers and research groups in the Colombian territories. It is aimed to improve the efficiency and ease of access to bibliographic data in order to support stakeholders. As methodology, an adaptation of the Project Management Body of Knowledge was used, defining phases of analysis, design, coding and evaluation during the development of the software. The results obtained allowed to successfully verify and validate the system, to point out both disparities and contrasts with respect to the statistics offered by the Ministry of Science, Technology and Innovation, to acquire multiple organized data sets about scientific activity in Cauca, and to offer a tool for obtaining more data sets from other departments of the country. Finally, it is important to emphasize that this tool seeks to contribute to the incentive, strengthening and reliability of future analysis and conclusions in research work or decision-making by individuals and entities related to the subject.

Published: January 2025

The textile industry often utilizes dyes containing pollutants that cause irreparable damage to the environment and may have adverse effects onhuman health when discharged into water sources or soils. Therefore, it is essential to explore environmentally friendly alternatives, such asthe latest technologies involving microalgae. In this study, microalgae technology, specifically Chlorella vulgaris was utilized at a laboratory scalefor the bioremediation of wastewater from the textile industry. The culture conditions included a pH range of 7-8, a temperature between 17 °C and 20 °Cwith constant agitation, and a supply of red LED light. In the bioremediation process, three samples were used, each with its respective replicates, atconcentrations of 50%, 25%, and 12.5% by volume of wastewater, with an initial volume of 200 mL of microalgae for each. Results indicated bioremediation percentages exceeding 95%. Notably, it was observed that lower wastewater percentages correlated with higher bioremediation percentages. This observation suggests a potential relationship between concentration and efficacy. Considering the promising results, we propose a basic design for scaling up this process to an industrial level. This involves identifying the most suitable equipment and conducting corresponding calculations to optimize the efficiency of the bioremediation process.

Background

The minimal clinically important difference (MCID) is an important threshold to consider when evaluating the meaningfulness of improvement following an intervention. The JoyPop app is an evidence-based smartphone app designed to improve resilience and emotion regulation. Information is needed regarding the JoyPop app’s MCID among culturally diverse youth.

Objective

This study aims to calculate the MCID for youth using the JoyPop app and to explore how the MCID may differ for a subset of Indigenous youth.

Methods

Youth (N=36; aged 12-18 years) were recruited to use the JoyPop app for up to 4 weeks as part of a larger pilot evaluation. Results were based on measures completed after 2 weeks of app use. The MCID was calculated using emotion regulation change scores (Difficulties in Emotion Regulation–Short Form [DERS-SF]) and subjective ratings on the Global Rating of Change Scale (GRCS). This MCID calculation was completed for youth overall and separately for Indigenous youth only.

Results

A significant correlation between GRCS scores and change scores on the DERS-SF supported face validity (r=–0.37; P=.04). The MCID in emotion regulation following the use of the JoyPop app for youth overall was 2.80 on the DERS-SF. The MCID for Indigenous youth was 4.29 on the DERS-SF. In addition, most youth reported improved emotion regulation after using the JoyPop app.

Conclusions

These MCID findings provide a meaningful threshold for improvement in emotion regulation for the JoyPop app. They provide potential effect sizes and can aid in sample size estimations for future research with the JoyPop app or e-mental health technologies in general. The difference between overall youth and Indigenous youth MCID values also highlights the importance of patient-oriented ratings of symptom improvement as well as cultural considerations when conducting intervention research and monitoring new interventions in clinical practice.
Health Care Seeking Behavior for Neonatal Danger Sign And Associated Factors Among Mothers in Jigjiga City Administration, Somali Region, Eastern Ethiopia,2021. (Preprint)
Authors: FARAH Sr ALINOOR MOHAMED
Published: January 2025

BACKGROUND

Background: Approximately 7% of all newborns died, despite their families living close to a health facility. A study adds to the evidence that most families in rural areas do not seek care for their sick newborns, even when they recognize signs of danger. Still, those who do seek care do not do so on time or from quailed care providers. In Ethiopia, a country where the neonatal mortality rate is high, raising the awareness of mothers on the danger signs of neonates and appropriate healthcare-seeking behavior is crucial to sustain the achievement.

OBJECTIVE

This study aims to assess the healthcare-seeking behavior for neonatal danger signs and associated factors among mothers in Jigjiga city administration, Somali region, Eastern Ethiopia, in 2021.

METHODS

The community-based cross-sectional study was carried out from April to May, 2021G.C. A structured pre-tested questionnaire was used, with a sample size of 408 mothers/caretakers to collect data. Data entering, coding, and clearing were performed using Epi data version 3.1 and analyzed using SPSS version 23, bivariate and multivariate analysis was conducted considering significance. A p-value of less than 0.05 was taken as a significant association.

RESULTS

Result: About 250(62.5%) of the mothers have no healthcare-seeking behavior while 150(37.5%) of the mothers have healthcare-seeking behavior for neonatal danger signs 54(26%) of neonates manifested difficulty/fast breathing. having information about neonatal danger signs were 5 times more likely to seek health care for their sick neonate than those who did not have information about neonatal danger signs 5.21(AOR:5.21,95%CI:0.86,31.41) and being knowledgeable about complications of neonatal danger sign were 11 times more likely to seek neonatal medical care compared to mothers who did not know11.35(AOR:11.35,95%CI:2.31,55.61). Those mothers who believe neonate or child can be treated with traditional were 3 times less likely to have healthcare-seeking behavior for neonatal danger signs.3.61 (AOR: 3.61 95% CI: 1.19,10.95)

CONCLUSIONS

Seeking suitable and timely care for neonatal danger signs is positively related to children`s healthy lives.
The perception of caretakers about the severity of neonatal danger signs ultimately affects the decision to seek health care and influences the type of care they receive.
Enhance our understanding of the factors that influence the healthcare-seeking behavior of the mother/caretakers in cases of neonatal danger signs. The caretakers, especially the mothers need to be educated about the importance of healthcare-seeking behavior for neonatal danger signs knowing neonatal danger signs and the source of information have a strong association with healthcare-seeking behavior,
Most of the respondents knew at least one danger sign of neonate mainly difficulty/fast breathing, lethargy/unconsciousness but other danger signs were not well recognized.

Purpose: Home is the place most at risk of exposure to cigarette smoke. Indonesia recorded that 85% of households are exposed to cigarette smoke. Smoke-free homes (SFH) were initially introduced by the Environmental Protection Agency, United States, 2001 to increase awareness of the health hazards of second-hand smoke (SHS) and one's ability to limit cigarette consumption in the home. The success and effectiveness of implementing smoke-free homes (SFH) cannot be separated from the modification of the behavior of each individual. This study aims to determine the effect of education and smoking-free house activity contracts on reducing the smoking intensity of husbands in the house in North Lombok Regency, West Nusa Tenggara.
Methods: This study is a retrospective, pre-, and post-intervention cohort study using secondary data from the Peer Health SHS-LBW Intervention Study in North Lombok Regency, West Nusa Tenggara Province. The data used were baseline data and 6-month data on 733 active smoking husbands who lived in the same house with pregnant women aged less than 4 months when they were respondents in the study. The data will be tested using Chi-square and logistic regression to determine the most influencing variables.
Results: The results of the chi-square analysis showed that most husbands with total income did not know/low income 66.67% did not experience changes or tended to increase the intensity of smoking in the house. In the comparative analysis, the value of p = 0.01 was obtained, which means a statistically significant relationship exists between the amount of income and the change in the smoking intensity of the husband in the house. Age, type of work, level of education, location of residence, and the respondent's willingness to attend education and smoke-free house activity contracts did not show a statistically significant relationship with changes in the husband's smoking intensity in the house (p-value>0.05).
Conclusion: Education and smoke-free house activity contracts (SFH) did not affect the reduction in the intensity of husbands' smoking in the house.
