Authors: Sally Enilce de Oliveira Fonseca , Gomes Daiane Silva , Dantas Lais de Oliveira Costa , Henriques Patrícia
Published: April 2024

Abstract The article aims to identify NBCAL violations and analyze the content of messages posted on the Instagram social network. This qualitative-quantitative study consisted of a convenience sample of profiles identified through specific terms preceded by the hashtag symbol (#). Data were collected for two months by trained researchers using a structured questionnaire. We calculated the product promotion frequency that characterized violation of the NBCAL per category and manufacturer. The messages were analyzed using the content analysis technique. We identified 64 personal accounts of mothers with violations in 89 products, mainly food (n = 72), dairy compounds (54.2%), and infant formulas (45.8%) were the most publicized. Two thematic categories emerged from the posted texts, one related to the quality of the products and the other about breastfeeding difficulty, especially low milk production. The study identified NBCAL violations on the Instagram social network, alerting the need to recognize digital marketing to include it in the rules imposed by the Norm in the virtual context, considering the capillarity of social networks in disseminating information to the public in question.

Published: April 2024

Abstract Floating structures, both natural and artificial, attract fish by providing shelter, feeding areas, and nesting sites. Occupancy can be either more permanent, leading to a gradual gathering of the assembly, or transient, occurring randomly. The ability of an attractor to hold a fish assemblage may depend on the availability of habitat resources in the environment. New artificial attractors are more valuable when natural ones are scarce. Additionally, fish characteristics play a role; young and small fishes may need new habitat for shelter more than adult fish. As aquatic herbaceous areas are abundant during high water, coinciding with the period of fish reproduction, they are particularly relevant for juveniles. We constructed fish attractors composed of natural materials to investigate the structure of fish assemblages during the flood of an Amazonian floodplain lake. Our aim was to test the hypothesis that assembly processes during the flood period would be random, with a predominance of juveniles in the attractors. We collected fish at intervals of 5, 15, and 30 days, resulting in 39 observations, and classified them as either adult or juvenile. Species composition was compared among treatments using Principal Coordinates Analysis (PCoA). The assembly process was tested through species co-occurrence patterns employing null models and the C-score index. The proportion of juveniles and adults was compared using a Chi-square test. Species composition remained consistent throughout the experiment. The assembly was random, with a prevalence of juveniles, possibly serving only as temporary shelter and feeding areas. Our study contributes to understanding the role of habitat availability for floodplain fishes during high waters. The results suggest that floating attractors and new habitats may be more valuable for the juveniles than adult fish and can be used as a management strategy for population recovery, especially when floating herbaceous habitats are scarce.

Published: April 2024

ABSTRACT Objective: to analyze the social representations of loneliness in older adults. Method: an exploratory and qualitative research study conducted in Lambayeque, Peru, by applying the Theory of Social Representations. A sociodemographic questionnaire was applied and in-depth interviews were conducted employing the semi-structured instrument with 32 older adults aged at least 70 years old, 50% belonging to each gender. Simple statistics and percentage analysis were applied to the sociodemographic data. The interviews were analyzed in the Alceste software program, subjecting them to lexicographic analysis. Results: the negative social representations refer to weak or impaired social relations with insufficient social support, thus vulnerabilizing older adults. The positive ones refer to pleasurable activities with no other people involved, assuming loneliness as adequate for intimacy, for listening to silence, for enjoying harmony and peace, for internal self-connection and for leading a pleasurable life, valuing it and strengthening the spiritual dimension. Conclusion: there is certain dialectics in the conception of loneliness: negative when it refers to the social context and to older adults' relationships with others; and positive when it represents an opportunity to embrace loneliness and perform pleasurable activities without depending on other people. It is indispensable to foster such positive aspects in the care provided to aged people.

INTERSECTORALITY AND GENDER MAINSTREAMING: AN ANALYSIS OF BRASIL CARINHOSO (2012-2015)
Authors: Cruz Maria do Carmo Meirelles Toledo , Marcondes Mariana Mazzini , Farah Marta Ferreira Santos
Published: April 2024

Abstract Our purpose in this article is to analyze Brasil Carinhoso from 2012 to 2015 through the theoretical lenses of mainstreaming and intersectorality, and highlight those dimensions of care it covers. Brasil Carinhoso was a federal child development initiative, which linked aspects of children’s education, health, social assistance and nutrition. Based on a qualitative analysis of official documents and interviews, we provide evidence of an intersectoral concept of the program, which included innovations in funding and management, even though its implementation was largely sectoral. We were unable to identify evidence of gender mainstreaming, not even in the conception of the initiative we analyzed, especially because the approaches to care adopted in Brasil Carinhoso fail to take into consideration those who provide the care, and focus only on those who are cared for.

Authors: Cheng Ye , Wang Ping , Liu Lidan
Published: April 2024

Ovarian cancer is one of the most common malignant tumors in female reproductive organs. Its incidence rate is second only to uterine body cancer and cervical cancer, posing a serious threat to women's health. Herein, we explored that PFKFB3 in cancer progression of ovarian cancer and its underlying mechanism. All the serum samples from ovarian cancer were collected by our hospital. PFKFB3 mRNA expressions in patients with ovarian cancer and ovarian cancer cell lines were up-regulated. PFKFB3 protein expressions in ovarian cancer cells were induced. ovarian cancer patients with high PFKFB3expression had lower survival rate. The PFKFB3gene promoted cell proliferation and EDU cells, and increased cell metastasis of ovarian cancer. Si-PFKFB3 reduced cell proliferation and EDU cells, and decreased cell metastasis of ovarian cancer. PFKFB3 gene up-regulation reduced caspase-3/9 activity levels of ovarian cancer. Si-PFKFB3 also promoted caspase-3/9 activity levels of ovarian cancer. PFKFB3 gene promoted Warburg effect progression of ovarian cancer. PFKFB3 gene reduced NLRP3-induced pyroptosis of ovarian cancer. PFKFB3 suppressed NLRP3 expression. NLRP3 was one target spot for PFKFB3 on pyroptosis of ovarian cancer. Taken together, we conclude that PFKFB3 suppressed NLRP3 axis to reduce pyroptosis and increase Warburg effect progression of ovarian cancer, and provide molecular insight into the mechanisms by which the PFKFB3 regulates pyroptosis of ovarian cancer.
UNRAVELING CONSUMER PURCHASE JOURNEY USING NEURAL NETWORK MODELS
Authors: Churchill Victor , Li H. Alice , Xiu Dongbin
Published: April 2024

This study utilizes an ensemble of feedforward neural network models to analyze large-volume and high-dimensional consumer touchpoints and their impact on purchase decisions. When applied to a proprietary dataset of consumer touchpoints and purchases from a global software service provider, the proposed approach demonstrates better predictive accuracy than both traditional models, such as
logistic regression, naive Bayes, and k-nearest neighbors, as well as ensemble tree-based classifiers, such as bagging, random forest, AdaBoost, and gradient boosting. By calculating the Shapley values within this network, we provide nuanced insights into touchpoint effectiveness, as we not only assess the marginal impact of diverse touchpoint types but also offer a granular view of the impact
distribution within a touchpoint type. Additionally, our model shows excellent adaptability and resilience
with limited data resources. When the historical data is reduced from 40 to 1 month, our model shows only a modest 19% decrease in accuracy. This modeling framework can enable managers to more accurately and comprehensively evaluate consumer touchpoints, thereby enhancing
the effectiveness and efficiency of their marketing campaigns.

Abstract—Engineering is one of the most preferred career options for the students. Although this field has witnessed a decline in the recent past, the impact of this decline on reputed educational institutes is negligible. Students line up for admissions in premier institutes and prefer to wait beyond the final round up to the spot round. A study was conducted in a premier unaided engineering college to design an approach for attracting students resulting in maximum allotment and conversion of the allotted students in actual admissions. Perception of the students admitted in the institute from A.Y. 2017-18 to A.Y. 2021-22 was collected to understand factors in selecting the institute. Correlation analysis was employed to analyze the perception of 839 students of A.Y. 2021-22. Weights of the factors revealed that three out of the nine factors accounted for more than 50% of the student perceptions. Certain initiatives were undertaken at the institute level to achieve 100% CAP allotment and conversion of the allotted students into actual admissions. As a result of these initiatives, a significant change was noted in the allotment and conversion of the allotted students into actual admissions. During the A.Y. 2023-24, the allotment was 100% and 64.36% of the allotted students accepted their seat and reported to the institute within the first two rounds. Around 93.31% of students reported in for admissions in three rounds. The institute initiatives also influenced the preference code option exercised by the students while filling the admission option form. It was observed that during A.Y. 2022-23 and A.Y. 2023-24, more than half of the students admitted in the institute had provided a preference choice for their admission between 1 and 10 thereby indicating that they were mostly inclined to seek admission in one of the ten branches offered by the institutenumber of students and increase the conversion rate of students allotted during the centralized admission process.

The central problem addressed in this paper is the separation of Engineering Studies from the Humanities in our current engineering curriculum resulting in a myopic educational approach that does not take into consideration the holistic nature of either the planet or the engineering education. This separation of the humanities from the sciences, particularly engineering, has made it impossible for the engineering fraternity to effectively contribute to our twenty-first-century society. In other words, if all engineering problems are primarily human problems, then engineers need to be trained not only in the technical skills of engineering but also in social and human skills that enable the engineer to equally navigate the human world for whom all solutions are built. In this paper after exploring the problem, data is presented from the curriculum innovation that is currently underway at the Plaksha University. A case study of the course section ‘Entangled Epistemologies’ of a new transdisciplinary course called ‘Entangled Worlds’ is given. This paper demonstrates how the curriculum has been designed uniquely with contributions from both Engineering Sciences and the Humanities and thus is able to deliver a holistic understanding.

Abstract— Understanding the complex landscape of alcohol consumption patterns among engineering students is crucial for shaping informed interventions and support systems. While prior research has primarily focused on aspects such as the prevalence of alcohol use and its consequences, there exists a significant gap in comprehensively exploring the underlying factors and implications. This research paper aims to bridge this void by exclusively addressing the intricate web of alcohol consumption within the engineering student demographic.The study delves into a multifaceted analysis that encompasses five paramount parameters: social influence, self-regulation, craving, coping strategies, and the environmental context. To achieve this, a meticulously designed survey instrument was deployed to engineering students at an autonomous college during the specified time frame. The collected data underwent rigorous exploratory factor analysis, resulting in the identification of five hypothesized factors that intricately define the landscape of alcohol consumption among engineering students.The reliability of this research instrument was validated through Cronbach's α values, which exhibited a range from 0.60 to 0.79 and had a minimum and maximum factor loading of 0.49 and 0.62 attesting to the robustness of the instrument. This valuable tool is poised to aid educational institutions in assessing their engineering students' current levels of awareness concerning alcohol consumption patterns and their underlying factors. Furthermore, it offers a foundation for evidence-based strategies aimed at fostering responsible drinking behaviors and tailored support systems, ultimately enhancing the well-being and academic success of engineering students.

Opioid-free anesthesia using a combination of ketamine and dexmedetomidine in patients undergoing laparoscopic cholecystectomy: a randomized controlled trial
Authors: K R Vishnuraj , Singh Kunal , Sahay Nishant , Sinha Chandni , Kumar Amarjeet , Kumar Neeraj
Published: April 2024

Background: Opioids administered as bolus doses or continuous infusions are widely used by anesthesiologists worldwide for major and day care surgeries. Opioid-free anesthesia is a multimodal anesthesia and analgesia technique that does not use opioid drugs, thereby benefitting patients from opioid-related adverse effects. In this study, we compared the postoperative analgesic requirements of patients scheduled for elective laparoscopic cholecystectomy under opioid-free and opioid-based anesthesia.Methods: This study included 88 patients aged 18–60 years with American Society of Anesthesiologists physical status 1 and 2 who underwent elective laparoscopic cholecystectomy. Participants were randomly divided into two groups with forty-four participants in each group. The opioid-free anesthesia group was administered an intravenous bolus of ketamine and dexmedetomidine, whereas the opioid-based group was administered fentanyl with conventional general anesthesia. The primary outcome was to compare the total amount of fentanyl consumed by both groups during the 6 h postoperative period following extubation. Episodes of postoperative nausea and vomiting (PONV) and vital signs were noted throughout the postoperative period to analyze the secondary outcomes.Results: Both the groups had similar demographic characteristics. The opioid-free group required less postoperative analgesia within the first 2 h (61.4 ± 17.4 vs. 79.0 ± 19.4 of fentanyl, P < 0.001), which was statistically significant. However, fentanyl consumption was comparable between the groups at the sixth postoperative hour (opioid-free group 152 ± 28.2 vs. opioid group 164 ± 33.4, P = 0.061). Compared with 4.5% of the participants in the opioid-free group, 34% of those in the opioid-based group developed moderate PONV.Conclusions: The opioid-free anesthesia technique in patients undergoing laparoscopic cholecystectomy reduced the requirement of analgesia in the first two hours of the postoperative period and was associated with decreased PONV.
Levels of heavy metals. Urban gardens in Bogota Colombia
Authors: Vega Castro Daniel Andrés , Vega Clavijo Lili Tatiana
Published: April 2024

Samples of lettuce, soil, and irrigation water from city gardens located in Bogota were analyzed in order to detect and quantify lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni), arsenic (As) and mercury (Hg). Metal concentrations of the soils and vegetables varied according to urban garden location; all detected metals in the soils and the lettuce were below health-based guidance values (local and international standards); heavy metals in irrigation waters were not detected; soils, metal concentrations of the irrigation waters and lettuce did not correlate. It means that urban agriculture should not represent a significant chemical risk for the consumer’s healthcare due to the possible intake of heavy metals and trace elements. However, it is necessary to continue conducting research on this important topic that is directly related to food security and food sovereignty and that will add information to update and establish a basis for reference levels regarding heavy metals in water, soil and vegetables.

Published: April 2024

The Development Agencies were established in 2006 in Türkiye to support regional development, with the budget transferred from the central government. The Development Agencies collaborate with public administrators, local governments, provincial administrations, universities, non-governmental organizations, and the private sector to adopt an effective governance model. The work of agencies in exceptional situations is also distinctive compared to other actors. It is crucial to evaluate the efforts of the Development Agencies in mitigating the social and economic impacts of the COVID-19 pandemic and draw conclusions about their effectiveness in the region. The impact of a pandemic outbreak on the Development Agencies has not yet been researched. This study aims to evaluate the work of the Serhat Development Agency and the effect of this new process on the local development of the region during the pandemic period, which continues its activities in the provinces of Agrı, Ardahan, Kars and Iğdır covering the TRA2 region of Türkiye. The study was conducted using the qualitative method. In-depth interviews were utilized during the field research in the agency between 19–29 October 2021 and 18–22 Jan uary 2023. The results obtained show that the pandemic process has reduced the interaction of the agency with its stakeholders and new projects have not been supported, which had a negative impact on the development of the region. Agriculture continued without any interr uption during the pandemic. Negative effects were seen in the tourism, food, and service sectors, but no additional efforts were made to remedy them.

Published: April 2024

In the digital age, the progression of digital government models presents a nuanced problem that this study meticulously investigates. Contextually, the inception of digital government in China has transpired through three distinct phases, each marked by a characteristic emphasis: technology-oriented, mutual transparency-oriented, and people-oriented. The analysis underscores a critical shift in emphasis across these stages, from an initial concentration on technological deployment to a present focus on mutual transparency and citizen engagement. Despite the evident progress, an issue emerges around capturing and articulating these stages with precision and objectivity. In response to this problem, this study undertakes an in-depth examination of case studies pertinent to each phase, which unravels insights into their defining characteristics. The findings indicate a potential trajectory towards a digital government model that further accentuates public participation.

This paper systematically identifies the determinants of COVID-19 death rates at the initial stages of the outbreak in Indonesia by considering configurations of government conditions (responsiveness, ability to control case rate, and capacity to cure infected people) and societal conditions (vulnerability and compliance). Configurational analysis using crisp-set QCA was employed to analyze these sets of conditions and outcomes in 34 provinces throughout Indonesia. The results show that the high ability of local government to control the spread of the disease is a necessary and sufficient condition for a low death rate. However, the opposite condition (the low ability of government) is only necessary but not sufficient for a high fatality rate. To create sufficient conditions for a high death rate, the low ability of local governments to restrain the spread of the virus requires other specific conditions, particularly a low level of community obedience to the restriction policy. The present study highlights that the institutionalization of a new normal life during the pandemic through regulative, normative and cultural-cognitive mechanisms is of paramount importance.

Pea (Pisum sativum L.) is a grain legume, a member of the Leguminosae family. Root-knot nematodes cause severe losses ranging from 15 to 85%. Different species of nematodes including root-knot nematodes reduce the yield of pea significantly. To control root-knot nematodes biological control is a more environment-friendly approach. The main objective of the study is to assess the effect of different antagonistic microbes and their secretory metabolites to manage root-knot nematodes in peas. Through this research, we aim to identify potential biological control agents that can be used as eco-friendly alternatives to chemical nematicides, contributing to sustainable pest management practices in agriculture. For this purpose, firstly, a brinjal seedling was transplanted for inoculum development which was inoculated with infective 2nd stage juveniles of root-knot nematodes (Meloidogyne spp.) in Department of Plant Pathology research area, University of Agriculture Faisalabad (UAF). Then two pea varieties viz. Matar sabaz and Pea-2009 were sown in pots and inoculated with nematode larvae after four weeks of sowing. Moreover, the management of nematodes was done by using the antagonists and their secretory metabolites application. The data of different plant growth and nematode-related parameters was taken and subsequently analyzed using analysis of variance and least significant difference test (LSD). Results showed that the antagonist’s treatment subsequently controlled root-knot nematodes (RKNs). Maximum plant/shoot length (47 cm), root length (25.25 cm), shoot weight (22.25 g) pod length (8.50 cm), No. of secondary shoots (8) and minimum number of galls (2.5 cluster), was observed in plants treated with Bacillus spp. (T1) while maximum No. of fruits (5.75) was observed in plants treated with Pseudomonas spp. (T2). Similarly, the number of nodules (7.50 clusters) primary shoots (5) Root weight (4.6 g) was observed in plants treated with Enterobacter spp. (T3).

Objectives: Current manuscript focuses on examination of chemical reaction and heat generation impacts on 3D MHD non-Newtonian nanofluid flow with convective boundary conditions induced by permeable sheet. Additionally, Brownian motion, non-Newtonian heating and thermophoretic processes as used for this study. Methods: A computational programme, MATLAB has been used for solving the system of O.D.Es with the help of ODE45 solver. The Runge Kutta Fehlberg approach is implemented to calculate the answer to the expression for temperature, velocity, and nanoparticle concentration after the shooting process. Findings: For a variety of fluid parameters, the temperature, concentration of nanoparticles, and dimensionless velocities are shown and examined, including permeability parameter , magnetic , stretching ratio parameter , Lewis number , Brownian motion and Prandtl number , thermal Biot number , Casson fluid parameter , chemical reaction parameter . The temperature is found to increase with an enhance in the thermal Biot number and to reduce with a greater Prandtl number and stretching ratio parameter. Novelty: Although the immense significance and frequent use of nanofluids in industries and technology, no effort has been made to explore the chemical influence on MHD Casson fluid flow using a three-dimensional permeable sheet. Through similarity transformations, the Runge-Kutta Fehlberg technique converts mass, momentum, and energy conservation equations into ODEs and incorporates boundary conditions. Skin friction and the heat transmission rate past an extending surface, which have an impact on technology and production, can be predicted using the results of this study.

Published: April 2024

Objectives: In this article, we aim to find a series of Hadamard matrices by suitable selection of the special class of matrices given in the Goethals and Seidel array and study the pattern obtained. Methods: In the presented work, the search technique of Hadamard matrices has been done by selecting special class of (0,1) negacyclic matrices instead of the back diagonal identity matrix given in Geothals and Seidel arrays and the possible existence of negacyclic matrices for the corresponding four matrices have been explored in each case. Findings: Corresponding to the special class of (0,1) negacyclic matrices, no sets of four negacyclic matrices have been obtained in the Goethal Seidel array, for even orders. For odd orders, except in the case when all four matrices are equal and the case when there is a pair of equal matrices, many outputs have been obtained for the remaining cases, the search domain being upto 11,9 and 7 for the case of two different, three different and four different matrices respectively, in the Goethal Seidel array. Novelty: The selection of special class of negacyclic matrices instead of the back diagonal identity matrix and finding the corresponding four negacyclic matrices in Goethals and Seidel arrays for constructing Hadamard matrices provides a new approach to the construction of Hadamard matrices. Keywords: Hadamard matrix, Circulant matrix, Williamson matrices, Orthogonal array, Goethals and Seidel array

Objectives: The purpose of the proposed IT-TALB load balancing algorithm is to dynamically allocate the user's workload to the appropriate virtual machine in an Infrastructure as a Service (IaaS) cloud environment. Methods: This research work includes several key procedures. The user's workloads are distributed to the data center controller (DCC), which in turn uses the ECO-SBP service broker policy to select the efficient data center (DC) for processing the loads. The DCC forwards the load to the selected DC, and the IT-TALB load balancer picks the best Virtual Machine (VM) using CloudAnalyst simulation tool for load allocations according to metrics such as its size, current number of loads, and load size. IT-TALB partitions the available and busy VMs separately and stores them in the TreeMap structure. This algorithm also incorporates the scalability of the given VM when the load size is not compatible with the existing VMs by extending the resources of underutilized VMs. Findings: The research finding demonstrates that the proposed IT-TALB algorithm improves IaaS cloud performance compared to the existing algorithms. It achieves optimum load balancing, reduces the searching time of the VM, avoids the load waiting time, improves throughput, minimizes the response time, and enhances the resource utilization ratio. IT-TALB yields a throughput and resource utilization ratio of 98 to 99 percent. Novelty: The novelty of this research is that the IT-TALB algorithm incorporates the scalability of the underutilized VM and also introduces new metrics such as throughput and resource utilization ratio in the CloudAnalyst simulation tool for assessing the performance of the proposed algorithm. This study provides information for analyzing the proposed IT-TALB strategies with the existing two algorithms such as TLB and TALB in order to show its performance.
