Problematic Social Media Use and Lifestyle Behaviors in Adolescents: Cross-Sectional Questionnaire Study
Authors: Ardesch Frank Hendrik , van der Vegt Denise Dorothy , Kiefte-de Jong Jessica Christina 
Published: November 2023

Abstract

Background
The use of social media by adolescents has increased considerably in the past decade. With this increase in social media use in our daily lives, there has been a rapidly expanding awareness of the potential unhealthy lifestyle-related health effects arising from excessive, maladaptive, or addictive social media use.

Objective
This study aims to assess the association between adolescents’ social media use and health-related behaviors.

Methods
We used a cross-sectional research approach and analyzed data from 96,919 adolescents at high schools throughout the Netherlands. A structured 43-item questionnaire was used to gather data on sociodemographics, dietary and lifestyle factors, and the degree of social media use based on the Compulsive Internet Use Scale. Logistic regression analyses were performed to assess the association between problematic social media use (PSMU) and lifestyle behaviors while adjusting for sociodemographic factors.

Results
Of the 96,919 included adolescents, 7.4% (n=7022) were identified as at risk for PSMU. Furthermore, logistic regression results showed that adolescents who are at risk for PSMU were more likely to report alcohol consumption and smoking while simultaneously having significantly lower levels of health-promoting behavior such as healthy eating habits (eating fruits, vegetables, and breakfast regularly) and physical activity.

Conclusions
This study confirms that adolescents at risk of PSMU were more likely to exhibit an unhealthy lifestyle. Being at risk for PSMU was a determinant of soft drug use, alcohol consumption, smoking, poor eating habits, and lower physical activity independent of the additional adjusted covariates including demographic variables and remaining lifestyle variables. Future research is needed to confirm this observation in an experimental setting.

Genotoxicity in humans exposed to arsenic and lithium in drinking water in the Bolivian Andes
Authors: Tirado Noemí , Mamani Josué , Loma Jessica De , Ascui Franz , Broberg Karin , Gardon Jacques 
Published: November 2023

Elevated concentrations of arsenic, lithium and boron in drinking water
have already been reported in the Bolivian Andes. Arsenic causes
genotoxicity but that caused by lithium and boron is less well known.
The aim of the present study was to evaluate associations between
arsenic, lithium and boron exposure and genotoxicity, while taking
genetic susceptibility into account. Women (n=230) were recruited in ten
villages around Lake Poopó. Arsenic exposure was determined as the sum
of concentrations of arsenic metabolites (iAs, MMA, and DMA) in urine.
Exposure to lithium and boron was determined based on their
concentrations in urine. Genetic susceptibility was determined by GSTM1
and GSTT1 null genotypes and AS3MT rs3740393,. Genotoxicity (DNA strand
breaks) was measured peripheral blood by the comet assay. Median
arsenic, lithium, and boron concentrations were 60 µg/L, 989 µg/L, and
3929 µg/L, respectively. GSTM1 and GSTT1 null carriers showed more DNA
strand breaks than gene carriers (p=0.008, p=0.005). We found no
correlation between urinary arsenic and DNA strand breaks (rS=0.03,
p=0.64), and only a weak non-significant positive association in the
multivariate analysis (β=0.09, p=0.14). Unexpectedly, increasing
concentrations of lithium in urine were negatively correlated with DNA
strand breaks (rS=-0.24, p=0.0006), and the association persisted in
multivariate analysis after adjusting for arsenic (β=-0.22, p=0.003). We
found no association between boron and DNA strand breaks. The lack of
genotoxic effect of arsenic could be associated with the specific
metabolic adaptation to arsenic previously reported in this population.
The apparent protective effect of lithium against genotoxicity merits
further investigation.
About the Results of a Trip to the Selkup Porg at the Parusovye Lakes
Authors: Степанова Ольга Борисовна 
Published: November 2023

Описываются результаты поездки автора к селькупскому порге – изображению духа на дереве, расположенному на промысловых угодьях на р. Парусовой, правом притоке среднего Таза. К итогам поездки относится научная фиксация памятника и проведенного обряда кормления духов, а также ряд выводов, вытекающих из анализа собранного материала. Главным открытием исследования стало отождествление духа-женщины, вырубленной в порге, с главным селькупским божеством Жизненной Старухой Илынтыль кота, детально описанным в работах Е. Д. Прокофьевой, после чего порге обрело развернутую характеристику, а божественная Старуха получила визуализацию в скульптурном изображении. Причем порге с Парусовых – пока единственное ее верифицированное изображение. Поездка к порге подтвердила, что вера в духов и их магическую силу у селькупов по-прежнему жива. Однако в отношении селькупов к данному духу были отмечены изменения. По заявлению хранителя, поскольку изображенная на порге Старуха является Хозяйкой всей земли, смотреть на нее, делать ей подношения и просить у нее покровительства и помощи могут все живущие на земле люди. В селькупской традиции такого широкого толкования круга лиц, имеющих доступ к порге, не было, поэтому подобное явление следует относить к новациям. Исследование выявило до сих пор неизвестное науке явление захоронения под деревом с порге домашних духов трех селькупских родов и дало ему предположительное объяснение.
The article describes the results of the author's trip to Selkup Porg - the image of the spirit on the tree, located on the fishing grounds on the river. Sailing, the right tributary of the middle Taz. The results of the trip include the scientific fixation of the monument and the ritual of feeding the spirit, as well as a number of conclusions drawn from the analysis of the collected material. The most important discovery of the study was the identification of a female spirit carved in a porg with the main Selkup deity, the Old Woman Ilyntyl Kota, described in detail in the works of E.D. Prokofieva, after which the Porg received a detailed characterization and a visualization of the divine Old Woman in a sculptural image. Moreover, the Porg of the Parusovs is her only verified image to date. The trip to the Porg confirmed that the belief in spirits and their magical power is still alive among the Selkups. However, changes were noted in relation to this spirit. Since the Old Woman depicted on the Porg is the mistress of all the Earth, all people living on Earth can look at her, make offerings to her, and ask her for protection and help, according to the Guardian. In the Selkup tradition, there was no such broad interpretation of the group of people who have access to the Porg, so this phenomenon is due to an innovation. The study has revealed the fact, still unknown to science, that the burial of the house spirits of three Selkup clans under a Porg tree provides a probable explanation.
The Canadian Fisheries Industry: Retrospect and Prospect
Authors: Hoogensen Gunhild 
Published: November 2023

Without question, Canadian domestic policy has had an influence on the development of the fisheries staple industry – from its National Policy to its subsidization of both fishers and, more recently its effort to conserve of fish stocks. In this respect Laxer is correct in allocating “blame” for the current dire status of the fisheries industry where it is, in part, due: on the Canadian government itself. However, it is also the case that trade liberalization, from the pressures exerted early on by the colonizing country of Britain, to the current dependency upon the US market for fish exports, has played an enormous role on the development, if not devastation of the industry.
In this respect the Canadian government could have done much more in the way of first recognizing the severity of fish stock depletion as well as fostering a sustainable fisheries industry that met the needs of conservation and fisher communities
The 2007 Provincial Election in Newfoundland and Labrador
Authors: Marland Alex 
Published: November 2023

On the surface, there was nothing special about the 2007 Newfoundland and Labrador general election, which saw Danny Williams re-elected for a second term as Premier. That his Progressive Conservatives would win a solid majority was never in doubt. There were no emerging issues, major gaffes or innovative campaign tactics, and few tight races. The de facto referendum on Williams’ leadership became a coronation. As Mackinnon (2007: 1) wrote about the Prince Edward Island election held five months earlier, “some campaigns are over before they begin.” In this case the only intrigue was how many Liberal or New Democratic Party candidates would form the opposition.
However the results do illustrate that a relatively homogenous electorate can rally around a leader who decries the province’s status in the Canadian federation. Furthermore, when elected officials from all major parties have been implicated in a scandal, many electors respond by not participating in politics. Political scientists can therefore draw comparative insights, such as asymmetrical federalism reminiscent of Quebec Premier Jean Lesage in the early 1960s, political scandal similar to the Grant Devine administration of Saskatchewan in the early 1990s, or about civic engagement generally.
The 2018 Provincial Election in New Brunswick
Authors: Gillies Jamie , Lewis JP , Bateman Tom 
Published: November 2023

New Brunswick’s 2018 election produced a minority legislature, the first in a century. The major parties continue to decline in voter support, and two new parties now have a presence in the Assembly. The election brings New Brunswick’s electoral politics increasingly into the modern Canadian mainstream; one new caucus is the Greens. In other respects, the election made the old new again. The populist People’s Alliance gained three seats partly on the basis of criticism of bilingualism policy. The Alliance and the Progressive Conservatives, in an informal alliance to govern, are all but confined to the anglophone parts of the province, while the defeated Liberals have all their strength in the Acadian north-east. The campaign mattered, as did constitutional conventions. The Liberals squandered a large lead in the polls, and the parties struggled to sort out the conventions of government formation.
Del paradigma eficientista al competitivo
Authors: Mas Fernando Francisco 
Published: November 2023

Este artículo presenta un esquema genealógico del proceso de racionalización del management desde el periodo fordista hasta el ascenso del postfordismo. Así, asumiendo una perspectiva sociológica e histórica, se remonta primero a los aportes del management científico y de corte eficientista de principios del siglo XX. Luego, el texto analiza la emergencia de la corriente estratégica managerial en los EE. UU. y de dos movimientos: la estrategia corporativa y la de negocios. En la estrategia corporativa, de los años 50 y 60, interesa reflexionar sobre los trabajos de autores pioneros como Peter Drucker. En la estrategia de negocios, de fines de los 60 y principios de los 70, se trae a colación los aportes empíricos de las consultoras de negocios, particularmente la curva de experiencia. Esto último para señalar, en los orígenes del management estratégico, la emergencia de un nuevo paradigma que hace de la competitividad, no de la eficiencia, su principio de ordenamiento reflexivo.
Experimental Investigation of Amplitude-Modulated Waves for Flame Extinguishing: A Case of Acoustic Environmentally Friendly Technology
Authors: Wilk-Jakubowski Jacek 
Published: November 2023

Abstract
Flame extinguishing methods that are safe for humans and non-invasive to the surrounding environment are being sought worldwide. One of them is acoustic technology, which appears to be an innovative and non-invasive means for flame extinguishing. A highpower and long-range extinguisher was built to explore the possibility of using this environmentally friendly technology. The article includes experimental results, obtained from a laboratory stand, on the possibility of extinguishing flames using amplitude-modulated waves depending on the frequency of the acoustic wave and the distance of the flame source from the extinguisher outlet, which is a scientific novelty. The advantages and disadvantages of acoustic technology are also analysed. The paper concludes that low-frequency acoustic waves are favourable for extinguishing flames because they cause more turbulence in the flame, and thus have a higher extinguishing efficiency. The results are promising and acoustic waves may be used to successfully extinguish flames in a wide range of firefighting scenarios in the future.

La modernización del	Distrito de Riego 001 inició en 2004, actualmente sigue en proceso de construcción y operando las secciones de riego completamente terminadas. El proyecto presenta cambios constructivos y de operación respecto al original, por lo que se planteó como objetivo analizar el comportamiento hidráulico de la red de distribución de la sección 01 en siete escenarios de operación, para identificar el más idóneo para el manejo del riego. La demanda de los 126 hidrantes de la sección de estudio se obtuvo por gasto modular, asignando aleatoriamente uno de los cultivos del patrón. Se consideraron el patrón de cultivos e intervalo de riego actuales, y una precipitación nula en todos los escenarios. Los tres primeros escenarios consideran una distribución por turnos, con diferencias en las necesidades de riego y en las láminas horarias de los emisores. El cuarto escenario consideró una distribución mixta por turnos y a la demanda. Estos cuatro escenarios consideraron un intervalo de riego de 48 horas, tiempo de riego de 3.2 horas por turno y fueron simulados en el programa EPANET. El quinto, sexto y séptimo escenario consideraron una distribución a la demanda, aplicando la primera fórmula generalizada de Clément, con una garantía de suministro de 90, 95 y 99 %, respectivamente, con un intervalo de riego diario, y se implementaron en MATLAB. Los resultados indicaron que la red no está capacitada para operar con un riego a la demanda y que, ante el patrón actual de cultivos, un riego por turnos estrictos es una mejor opción.
Environmental Changes in a Key Region of the Pampa: A Quantitative Analysis of Land use in the Ibirapuitã Environmental Protection area (Rio Grande do Sul) and Surroundings
Authors: Pires Mateus Marques , Pallaoro Rafaela Bellin , Périco Eduardo 
Published: November 2023

Objective: To analyze land use patterns in the Environmental Protection Area (APA) of Ibirapuitã (Rio Grande do Sul, RS) and surrounding municipalities between 1985 and 2022.

Theoretical framework: Although the South Brazilian Pampa biome is traditionally associated with low-impact agriculture, there is a recent advance in the conversion of natural vegetation in areas of remnants of native fields such as southwestern RS. This region is home to the Ibirapuitã APA, the largest conservation unit in the Pampa biome in RS (more than 300,000 ha).

Methods: Based on land use maps obtained from the MapBiomas platform, the areas of each land use class were extracted and quantified using geoprocessing techniques. We then compared the annual trajectories of land use classes in the internal perimeter of the APA and the surrounding area using descriptive statistics.

Results: During the analyzed period, the areas of natural land use classes (native grassland and forest) remained stable within the APA, while in the surrounding municipalities the areas of native grasslands were markedly reduced and mostly replaced by agriculture and urbanization.

Implications: The Ibirapuitã APA proved to be strategic for the conservation of native fields in this region of the southern Brazilian Pampas.

Novelty: By comparing land use trajectories in the internal perimeter and surroundings of the conservation unit, this study provides the first assessment of the effectiveness of the Ibirapuitã APA in maintaining the natural vegetation of the South-Brazilian Pampa biome.

La méconnaissance du cadre professionnel chez des enseignantes débutantes devant un problème éthique à l’école
Authors: St.Vincent Lise-Anne 
Published: November 2023

Cette recherche vise à mettre en évidence certaines dimensions que des enseignantes débutantes en adaptation scolaire examinent devant un problème d’ordre éthique rencontré à l’école. Quatre dimensions éthiques dans un problème de ce type sont considérées : les personnes impliquées, les valeurs en jeu, les principes de conduite professionnelle et le cadre professionnel. Cette recherche s’insère dans une approche qualitative. Par le moyen d’entrevues individuelles semi-dirigées, les dimensions qui ressortaient dans la réflexion de onze participantes devant un problème éthique ont été analysées. Les résultats obtenus dans cette recherche ont permis de faire ressortir que la dimension du cadre professionnel est très peu abordée par les enseignantes participantes. Les lois, les normes de la commission scolaire et de l’école ainsi que la convention collective semblent méconnues. À la lumière de ces résultats, des pistes pour la formation initiale et la période d’insertion professionnelle sont proposées. Ces pistes visent l’amélioration des connaissances qui s’avèrent fondamentales de ce système de régulation, et ce, dès l’entrée en pratique.
