Maternal self-efficacy and emotional well-being in Chilean adolescent mothers: the relationship with their children’s social-emotional development

Background Low maternal self-efficacy and high levels of anxiety, depression, and stress can be triggered in adolescent mothers due to an incomplete development process that makes them physically or psychologically unprepared for the responsibilities of motherhood and parenting. These factors may be linked to difficulties with their children’s social-emotional development. The present study aims to: (a) analyze the relationship between maternal self-efficacy and stress, depression, and anxiety levels in low-income adolescent mothers; (b) examine the relationship between maternal self-efficacy and well-being with children’s social-emotional development; and (c) describe the effects of maternal self-efficacy on children’s social-emotional development, mediated by maternal well-being. Methods A sample of 79 dyads comprising low-income Chilean adolescent mothers aged from 15 to 21 years old (M = 19.1, SD = 1.66) and their children aged 10 to 24 months (M = 15.5, SD = 4.2) participated in this research. A set of psychometric scales was used to measure maternal self-efficacy (Parental Evaluation Scale, EEP), the mothers’ anxiety and depression (Hospital Anxiety and Depression Scale, HADS), maternal stress (Parental Stress Scale, PSS), and the children’s social-emotional development (Ages and Stages Questionnaire Socio-emotional, ASQ-SE). Bivariate analyses and mediation models were employed to estimate and test the relevant relationships. Results A bivariate analysis showed that maternal self-efficacy was negatively related to the mother’s anxiety, depression, and stress. Moreover, there was a significant relationship between maternal self-efficacy and maternal stress, and children’s self-regulation and social-emotional development. Maternal self-efficacy, mediated by maternal anxiety, depression, and stress scores, had a significant effect on the development of children’s self-regulation. Conclusions The results confirm the importance of adolescent mothers’ emotional well-being and maternal self- efficacy with respect to their children’s social-emotional development. This makes it necessary to have detailed information about how emotional and self-perception status influences a mother’s role in the development of her children.
A targeted capture approach to generating reference sequence databases for chloroplast gene regions

Abstract Metabarcoding has improved the way we understand plants within our environment, from their ecology and conservation to invasive species management. The notion of identifying plant taxa within environmental samples relies on the ability to match unknown sequences to known reference libraries. Without comprehensive reference databases, species can go undetected or be incorrectly assigned, leading to false‐positive and false‐negative detections. To improve our ability to generate reference sequence databases, we developed a targeted capture approach using the OZBaits_CP V1.0 set, designed to capture chloroplast gene regions across the entirety of flowering plant diversity. We focused on generating a reference database for coastal temperate plant species given the lack of reference sequences for these taxa. Our approach was successful across all specimens with a target gene recovery rate of 92%, which was achieved in a single assay (i.e., samples were pooled), thus making this approach much faster and more efficient than standard barcoding. Further testing of this database highlighted 80% of all samples could be discriminated to family level across all gene regions with some genes achieving greater resolution than others—which was also dependent on the taxon of interest. Thus, we demonstrate the importance of generating reference sequences across multiple chloroplast gene regions as no single loci are sufficient to discriminate across all plant groups. The targeted capture approach outlined in this study provides a way forward to achieve this.
Candidate Genes and Their Expressions Involved in the Regulation of Milk and Meat Production and Quality in Goats (Capra hircus)

Simple Summary During the present decade, highly selected caprine farming has increased in popularity due to the hardiness and adaptability inherent to goats. Recent advances in genetics have enabled the improvement in goat selection efficiency. The present review explores how genetic technologies have been applied to the goat-farming sector in the last century. The main candidate genes related to economically relevant traits are reported. The major source of income in goat farming derives from the sale of milk and meat. Consequently, yield and quality must be specially considered. Meat-related traits were evaluated considering three functional groups (weight gain, carcass quality and fat profile). Milk traits were assessed in three additional functional groups (milk production, protein and fat content). Abstract Despite their pivotal position as relevant sources for high-quality proteins in particularly hard environmental contexts, the domestic goat has not benefited from the advances made in genomics compared to other livestock species. Genetic analysis based on the study of candidate genes is considered an appropriate approach to elucidate the physiological mechanisms involved in the regulation of the expression of functional traits. This is especially relevant when such functional traits are linked to economic interest. The knowledge of candidate genes, their location on the goat genetic map and the specific phenotypic outcomes that may arise due to the regulation of their expression act as a catalyzer for the efficiency and accuracy of goat-breeding policies, which in turn translates into a greater competitiveness and sustainable profit for goats worldwide. To this aim, this review presents a chronological comprehensive analysis of caprine genetics and genomics through the evaluation of the available literature regarding the main candidate genes involved in meat and milk production and quality in the domestic goat. Additionally, this review aims to serve as a guide for future research, given that the assessment, determination and characterization of the genes associated with desirable phenotypes may provide information that may, in turn, enhance the implementation of goat-breeding programs in future and ensure their sustainability.
A REVIEW ON CONGESTION CONTROL ALGORITHMS IN MANET

In wireless network communication mobile communication has becomes very significant. MANET is a temporary network that means nodes transfer without any fixed infrastructure. In MANET changes the network topologies due to nodes are movable and also nodes are commonly communicated with each other over various wireless links. In MANET routing is a problem because there is no router between source and destination so mobile nodes also themselves act as the routers. In MANET, routing based on the topologies, router source. Congestion control is a major problem in MANET. Congestion means when transmit the number of packets across the network is larger than the capacity of the network then network becomes congested. Due to congestion the packets have to be deleted and also reduce the performance of the network. To finding the congestion free shortest path is a main issue in MANET.
E-WOM effect through social media and shopping websites on purchase intention of smartphones in India

This study analyses the comparative effects between E-WOM on online shopping platforms and social networking platforms on consumers’ purchase intention of smartphones in India. The E-WOM effect on buying intention has become an important context for many researchers due to its increasing importance in today’s world of digitalization. This study aims to assess the influence of E-WOM factors on these two platforms, including E-WOM credibility, E-WOM attitude, E-WOM quantity, and E-WOM format, on purchase decisions of smartphones. The data were collected using a questionnaire from 361 respondents in Uttar Pradesh, India. Multiple regression has been applied to empirically measure the influence of independent factors (E-WOM credibility, E-WOM attitude, E-WOM quantity, and E-WOM format) on the dependent factor (consumers’ purchase intention). The result indicates that E-WOM credibility, E-WOM quantity, and E-WOM format on online shopping platforms have more impact than E-WOM on social media on the purchase intention of smartphones. This study aids online companies in understanding the purchase patterns of consumers, and E-WOM on online shopping platforms is more effective in terms of credibility, quantity, and format as compared to E-WOM on social networking platforms toward buying intention of smartphones.
REAL-TIME WET/DRY ROAD SURFACE DISCRIMINATION US- ING ROLLING NOISE ACOUSTIC FOOTPRINT ANALYSIS

Road surface changes due to the weather conditions have a major influence in driving safety. To avoid accidents, drivers must adapt their driving style according to the road status. This adaptation mechanism depends on the driver ability to detect the pavement conditions. Unfortunately, this is often a difficult task. A system capable of notifying the driver about changes on the road surface due to weather aspects, could improve this adaptation mechanism, thus reducing accident risk. An electronic system capable of estimating the road surface status between dry and wet status is presented. The system is mainly based on the analysis of the tyre/road noise generated during driving. The sound emission pattern of the tyre/road interaction changes depending on whether the pavement is dry or wet. Thus discriminating the tyre/road noise acoustic footprint, it is possible to estimate the road status. Proposed system captures and digitizes tyre/road noise. Rolling noise is pre-processed extracting its spectral components to construct the feature vectors. Feature vectors are processed by a Support Vector Machine (SVM) based classifier. Then the classifier outputs the road surface status estimation. The first implementation of the system, using Matlab along with pre-recorded tyre/road noise, shows high success rates (around 91%). These promising results are leading to the development of a hardware prototype, tightly integrated with the vehicle, and capable of computing the classification algorithms in real time.

Investigation of an efficient model-based fuel economy optimization methodology for diesel engines focusing on real world driving emission cycles

Together with stringent emission standards, meeting fuel consumption, and performance targets have made engine calibration process complicated, lengthy, and costly. For this reason, it is crucial to develop an efficient methodology for the optimization of a diesel engine calibration. In this study, a novel automated fine tuning methodology using genetic algorithms and data driven models is proposed. Fuel consumption of a light commercial vehicle with 2.0-L diesel engine was optimized for a predefined Real Driving Emissions (RDE) cycle. During the optimization, tail pipe emission limits were maintained by taking the aftertreatment system efficiency into account. To this end, a representative engine control unit, internal combustion engine, and Selective Catalyst Reduction (SCR) system models were built by using empirical data and neural networks. Moreover, the effect of choosing different tailored optimization points for a predefined route was investigated by comparison of frequency and fuel consumption based weighting. The cost function, related to the optimization problem, was defined based on fuel consumption, performance, and mechanical limits of the engine, and in accordance with tailpipe emission limits defined by Euro 6d-Temp regulations. Compared to previous model-based calibration studies, tailpipe emissions, and regulation limits have been incorporated in this study in order to obtain more realistic calibrations. After testing different genetic algorithm configurations, the fuel efficiency over the predefined route was improved by 3.07% without violating any of the limits while the smoothness of the calibration maps was also preserved. This route specific calibration methodology is believed to have the potential to increase fuel economy in real world applications such as daily commuting routes or repetitive driving patterns for instance, operation vehicle use cases in factories, airports, and construction areas. As for further development, this can be achieved by running simulations and the optimization on cloud and updating the calibration remotely based on the selected route before the trip.
Capabilities and Practices in DevOps: A Multivocal Literature Review

Context. To meet the demands of customers and market, Information Technology (IT) organizations are seeking to implement DevOps. While many succeed in DevOps adoption, others lack the knowledge on how to incorporate DevOps culture, process, measurements, and techniques in their business. Thus, successful adoption is still inconsistent, highlighting the need to provide management with relevant information to support the development of DevOps Capabilities effectively. But what are these Capabilities? Unfortunately, there is still a lack of clarity about DevOps Capabilities and their relationships to DevOps Practices and Outcomes among researchers and practitioners. Objective. This research aims to gather community consensus on the relationship between Capabilities and Practices, so a better DevOps implementation can be mapped. Seeking to define DevOps Capabilities and Practices concepts and to identify, organize and summarize Capabilities as they relate to Practices. Method. A Multivocal Literature Review (MLR) is conducted, with 93 documents gathered and thoroughly examined from throughout the community, including books, scientific articles, white papers, and conferences, among others. Results. This survey contributes a list of 37 organized Capabilities, their mentions in literature, and their definitions. The concepts of Practices and Capabilities were mapped and categorized in an ordered taxonomy. It is concluded that industry research has much outweighed scientific research on this topic, with Capabilities evolving dynamically over time, reinforcing team collaboration and communication as the most crucial one. The study's Outcomes will assist researchers and practitioners understand how Capabilities and Practices are related at different levels and how to better implement them.
Microencapsulation of Natural Food Antimicrobials: Methods and Applications

The global demand for safe and healthy food with minimal synthetic preservatives is continuously increasing. Some natural food antimicrobials with strong antimicrobial activity and low toxicity have been considered as alternatives for current commercial food preservatives. Nonetheless, these natural food antimicrobials are hardly applied directly to food products due to issues such as food flavor or bioavailability. Recent advances in microencapsulation technology have the potential to provide stable systems for these natural antibacterials, which can then be used directly in food matrices. In this review, we focus on the application of encapsulated natural antimicrobial agents, such as essential oils, plant extracts, bacteriocins, etc., as potential food preservatives to extend the shelf-life of food products. The advantages and drawbacks of the mainly used encapsulation methods, such as molecular inclusion, spray drying, coacervation, emulsification, supercritical antisolvent precipitation and liposome and alginate microbeads, are discussed. Meanwhile, the main current applications of encapsulated antimicrobials in various food products, such as meat, dairy and cereal products for controlling microbial growth, are presented.
Performance evaluation of Serial and Parallel Concatenated Channel Coding Scheme with Non-Orthogonal Multiple Access for 6G Networks

In recent years, the advent of 6G and intelligent devices, sensors, and new applications like virtual reality and autonomous driving, user data traffic has exploded, especially video traffic and small IoT packets. These bandwidth-hungry applications require increased network capacity and user access. 6G network may use non-orthogonal multiple access (NOMA) instead of orthogonal multiple access (OMA) to maintain higher data rates, throughput, and lower latency. On the other hand, choosing the channel coding method for future 6G mobile communication is critical to maintaining the high demands for 6G. This paper proposes two-channel coding structures to achieve higher data rates with lower error rate floor; these structures are polar convolutional serial code (PCSC) and polar convolutional parallel code (PCPC); these structures can achieve larger channel capacity and reduced bit error rates when used with NOMA. The obtained simulation results showed that bit error rate (BER) performance improves overall coding gain by 1.2 dB compared to polar code in fifth-generation (5G). PCSC surpasses PCPC with a 1.5dB coding gain. This performance ranges between 4 to 6.25dB with higher system settings. The obtained throughput results show improvement with 56-60%, which the enhancement percentage depends on the modulation method used in a direct proportion way.
Paleodiet of Lamini camelids (Mammalia: Artiodactyla) from the Pleistocene of southern Brazil: insights from stable isotope analysis (δ13C, δ18O)

Abstract. Camelids (Camelidae) were a diverse and widely distributed group in South America during the Pleistocene. According to the fossil record, three species inhabited southern Brazil in the recent past: Hemiauchenia paradoxa, Lama guanicoe, and Vicugna vicugna. The analysis of carbon and oxygen stable isotope ratios in bioapatite provides insight into the paleobiology of nonliving animals and the environment they used to inhabit. We applied this tool to investigate the diet of camelids from two geological localities in southern Brazil: Touro Passo and Santa Vitória Formations (H. paradoxa, n = 7; L. guanicoe, n = 6; V. vicugna, n = 4). Carbon stable isotopes from enamel, dentin, and bone indicated that H. paradoxa and L. guanicoe had diets comprising mostly C3 grasses, but the latter showed a broader diet due to one individual with a mixed diet, whereas V. vicugna had a mixed C3–C4 diet. These different foraging behaviors may have minimized interspecific competition and favored niche partitioning and the coexistence of related species. Combined oxygen and carbon isotope data showed a consistent diet according to climate, probably due to the greater availability in glacial periods of cool-season grasses, which mainly use the C3 photosynthetic pathway. Given their adaptations to grazing, the climate amelioration, followed by the loss of grasslands, likely had a great impact on camelid populations, leading to their extinction in southern Brazil. These results, therefore, contribute to the understanding of the dynamics of paleocommunities in this region.
High-Isolation Power Divider Based on Ridge Gap Waveguide for Broadband Millimeter-Wave Applications

In this article, a high-isolation power divider with ultrawideband characteristics for simultaneous operation in two adjacent bands is proposed. The power divider is developed based on a four-port coplanar Magic-T. The difference port of the Magic-T consists of a double-ridge gap waveguide (RGW) that supports quasi-TEM mode transmission, which provides the benefit of its broadband characteristics and allows for facilitated assembly. In addition, an inline microstrip line (MSL) containing a probe is inserted into the opposite side of the difference port to form the sum port. This basic configuration has actually achieved high isolation between the output arms and low return loss at each port, and however, its isolation bandwidth is limited by the narrowband matching of the sum port. To overcome this difficulty, a three-port microstrip T-junction is connected in series to the sum port of the Magic-T, resulting in a five-port 3-dB power divider with a wide isolation bandwidth. The process of considering this solution is analyzed and explained in detail in this article and the corresponding simulations and experimental verifications are performed. According to the obtained results, the proposed power divider has excellent overall performance, in particular low loss, ultrawideband, high isolation, and good amplitude/phase consistency.
