This research aimed to compare the internalizing (anxiety and depression) and externalizing (hyperactivity) symptoms of Caraquenian children based on the level of food insecurity reported by their parents. A simple retrospective design was proposed with a sample of 200 children, aged between eight and twelve, and their representatives, in charge of reporting the food insecurity levels in their homes and the symptoms of perceived hyperactivity in their children. For the analysis of results, the non-parametric Mann-Whitney´s U technique was used to compare anxiety, depressive and hyperactive symptoms based on high and low levels of food insecurity. Results suggest moderate conditions of food insecurity in the households. Furthermore, regarding the set of internalizing symptoms evaluated, it was found that households with greater food insecurity tend to have children with greater manifesta...

Intercultural communication is considered a progressively developing trend, both abroad and in modern Russia. The concept of Western research on this topic is interdisciplinary approaches this situation is conditioned by the need for a multilateral analysis of the processes taking place in this field. Attention is focused on studying the barriers to communication of representatives of many socio-cultural systems. The information reflects the experience of using Western methodology to analyze the problems of intercultural interaction. The main barriers that reduce the effectiveness of interactions are the differences in cognitive schemes that are relevant for representatives of certain cultures (in particular linguistic and non-verbal schemes, moments of public consciousness). The results of the study do not allow the dissemination of conclusions to an extremely broad social context. But ...

The purpose of this paper is to study the vibrational behavior of advanced composite plates by using a novel first shear deformation theory (FSDT). This theory contains only four unknowns, with is even less than the classical FSDT. The governing equations are derived by employing the Hamilton's principles and solved via Navier's solution. The present results were validiated by comparing it with the 3D, classical FSDT and other solutions available in the literature. Shear correction factor apper to be unfovarable in some cases (case dependent). Finally, authors recommend further study of this new manner to model the displacement field.

Purpose. This paper aims to test the hypothesis that the effect of production slowdown on labour demand can be muted by labour hoarding. Design/methodology/approach. This study adopts a production function approach, using data from Malta, a small state in the EU. Findings. The results confirm the hypothesis and indicate that firms are normally prepared to employ and dismiss more workers in the long run than in the short run. Practical implications. This finding has important implications for developed countries, including that labour hoarding can be of certain relevance in times of economic slowdown as shocks are absorbed by internal flexibility. Originality/value. The results of this study add on to the existing literature in two ways. First, this study compares two industries –manufacturing and financial services– for which the former sector received support to hoard labour after t...

The closed-form solution of a generalized hybrid type quasi-3D higher order shear deformation theory (HSDT) for the bending analysis of functionally graded shells is presented. From the generalized quasi-3D HSDT (which involves the shear strain functions “f(ζ)” and “g(ζ)” and therefore their parameters to be selected “m” and “n”, respectively), infinite six unknowns' hybrid shear deformation theories with thickness stretching effect included, can be derived and solved in a closed-from. The generalized governing equations are also “m” and “n” parameter dependent. Navier-type closed-form solution is obtained for functionally graded shells subjected to transverse load for simply supported boundary conditions. Numerical results of new optimized hybrid type quasi-3D HSDTs are compared with the first order shear deformation theory (FSDT), and other quasi-3D HSDTs. The...

This paper presents a static analysis of functionally graded plates (FGPs) by using a new first shear deformation theory (FSDT). This theory contains only four unknowns, with is even less than the classical FSDT. In this paper a simply supported FG square sandwich plate is subjected to a bi-sinusoidal load. The governing equations for static bending analysis are derived by employing the principle of virtual works. These equations are then solved via Navier-type, closed form solutions. The accuracy of the present theory is ascertained by comparing it with various available solutions in the literature.

In the competition of the lighting market, LED technology has stood out for excellent characteristics, one of which is the possibility of dimming, compared to other technologies. The dimming capacity allows to find the comfort zone with respect to two parameters, illuminance and correlated colour temperature (CCT). The present work provides a methodology to find comfort with respect to two variables, the level of illumination and the CCT. A controller with a simple structure, supported by Arduino, is proposed to control the above-mentioned variables of LEDs. The LEDs are located on a tape attached to a heat sink. In addition, the use of a light box as an environment for analysis is proposed. The design of this cubicle is based on literature. The controller has the possibility to regulate 12 different channels and the linearity between the PWM output and the illuminance was verified. The ...

Universities have become brands that use Instagram to attract potential students and generate a sense of community among actual members. This study aims to compare how the best-positioned universities in the world and in Spain, according to the Shanghai ranking, use Instagram as a communication channel. To do this, a mixed descriptive exploratory analysis is chosen, combining qualitative variables, format, discursive intention and function of the visual element; and quantitative, interactions and engagement, to analyze the posts from the first trimester of the 2021/2022 academic year (N = 820). The combined interpretation of both parameters after applying the ANOVA variance test has allowed us to formulate two preliminary publication models. The results reveal heterogeneity in the strategies followed, with differences in format, intention and function of the visual element, in addition t...

Polyethylene terephthalate (PET) is a widely used material in container manufacturing, particularly in bottle production. It is characterized by its low cost and widespread availability. However, its improper disposal has significantly exacerbated global plastic pollution. For instance, less than 50% of plastic bottles are recycled. Moreover, studies indicate that this issue has led to a significant accumulation of plastic waste in the oceans, which continues to grow annually and could be considered floating islands of debris. This study proposes replacing PET with polylactic acid (PLA), a biodegradable and biocompatible polymer with suitable properties for bottle production. PLA also has a shorter decomposition time compared to PET, contributing to the reduction of carbon footprint and greenhouse gas emissions. The research methodology included a diagnostic phase to define objectives, i...
