Promoting healthy use of screen media among preschool children
No full textUvod: Otroci so zaslonskim medijem pogosto izpostavljeni že vse od rojstva naprej in so postali nepogrešljiv sestavni del vsakdanjega življenja. Kljub vsem pozitivnim in koristnim učinkom pa dolga in nezdrava raba zaslonskih medijev med otroki in mladostnik postaja vse pomembnejši javnozdravstveni izziv, saj prestavlja veliko tveganje za pojav negativnih učinkov na njihov razvoj in zdravje. Namen: Namen pregleda literature je raziskati negativne posledice, ki jih ima prekomerna raba zaslonskih medijev na razvoj in zdravje predšolskih otrok ter ugotoviti uspešne pristope, strategije in intervencije, ki bi jih lahko izvajale medicinske sestre pri delu s predšolskimi otroki in njihovimi starši. Metode dela: Narejen je bil pregled znanstvene literature, objavljene v angleškem jeziku od januarja 2015 do maja 2025. Iskanje je potekalo v bibliografskih zbirkah CINAHL Ultimate, MEDLINE in ERIC. V končno analizo je vključenih 15 člankov. Rezultati:. Medicinske sestre imajo ključno vlogo pri preprečevanju negativnih posledic prekomerne rabe zaslonskih medijev med predšolskimi otroki. Izvajajo lahko izobraževanja in vzgojo za zdravje staršev ter tudi izobraževanja zdravstvenih delavcev in vzgojiteljev. Začnejo lahko s spodbujanjem razvoja zdravih vedenj in življenjskega sloga že v zgodnjem otroštvu ter delujejo na področju preprečevanja prekomerne rabe zaslonskih medijev ter posledično zmanjšanje tveganja za pojav negativnih vedenjskih navad in s tem negativnih posledic na razvoj in zdravje predšolskih otrok. Razprava in zaključek: Medicinske sestre imajo osrednjo vlogo pri spodbujanju zdrave rabe zaslonskih medijev pri svojem preventivnem delovanju na različnih ravneh zdravstva z izvajanjem različnih intervencij, ki so osredinjene na otroke, starše, vzgojitelje in tudi druge zdravstvene delavce. Vzgojo za zdravje tako staršev kot otrok in mladostnikov izvajajo v sklopu sistematskih zdravstvenih pregledov in v sodelovanju z vzgojno-izobraževalnimi zavodi. V slovenskem prostoru se tej temi že namenja določeno stopnjo pozornostiprav tako na tem področju že deluje več nevladnih organizacij. Nadaljnje raziskave za pridobitev podatkov o ozaveščenosti različnih deležnikov glede te problematike, njihovem znanju, uspešnosti izvajanja izobraževanj na to temo, lahko služijo za nadgradnjo uspešnih preventivnih programov, saj se pričakuje naraščanje problematike. Prav tako je smiselno vključiti vsebino v študij zdravstvene nege.Introduction: Children are often exposed to screen media from birth, and screen media has become an integral part of everyday life. Despite their positive and beneficial effects, prolonged and unhealthy screen media use among children and adolescents is becoming an increasingly important public health concern, as it poses a significant risk of negative effects on their development and health. Purpose: The purpose of this literature review is to investigate the negative consequences of excessive screen media use on the development and health of preschool children and to identify effective approaches, strategies, and interventions that nurses could implement when working with preschool children and their parents. Methods: A review of scientific literature published in English from January 2015 to May 2025 was conducted. The research was carried out in the bibliographic databases CINAHL Ultimate, MEDLINE, and ERIC. We included 15 articles in the final analysis. Results: Nurses play a key role in preventing the negative consequences of excessive screen media use among preschool children. They can provide education and education for health for parents, as well as training for healthcare professionals and educators. Nurses can begin encouraging the development of healthy behaviors and lifestyles in early childhood and focus on the prevention of excessive screen media use and, consequently, reducing the risk of negative behavioral habits and thus negative consequences for the development and health of preschool children. Discussion and conclusion: Nurses play a central role in promoting healthy screen media use through their preventive activities across various levels of the healthcare system by implementing a range of interventions targeting children, parents, educators, and other healthcare professionals. Education for health for parents, children and adolescents is provided as part of systematic health examinations and in cooperation with educational institutions. In Slovenia, a certain amount of attention is already being paid to this topic, and several non-governmental organizations are active in this area. Further research is needed to obtain data on stakeholders’ awareness, knowledge and the effectiveness of education on this topic, which could contribute to the development and improvement of effective preventive programs, especially given the expected increase in the prevalence of this problem. Additionally, it would be reasonable to incorporate this content into nursing education curricula
The effect of trypsin and EDTA solutions on the stability of surface markers of MEF, B12, RAW264.7 and DC 2.4 cells at different time points
No full textJedan od prvih koraka prilikom analize adherentnih stanica na protočnom citometru je njihovo odljepljivanje od podloge i dobivanje stanične suspenzije, međutim ovaj postupak može utjecati na kompoziciju i integritet molekula ispoljenih na samoj površini stanice. Kako bismo to izbjegli, odlučili smo ispitati utjecaj otopina tripsin i EDTA na izražaj određenih proteina, s obzirom na vrijeme inkubacije. Proteini čija razina je praćena su molekule MHC I, m04 te CD80 na čiji izražaj utječe mišji citomegalovirus (MCMV) kako bi izbjegao prepoznavanje od stanica imunosnog sustava, a njihova regulacija i ekspresija predmet su intenzivnog istraživanja u Centru za proteomiku. Razine navedenih molekula proučavane su na stanicama MEF, B12, DC 2.4 i Raw264.7 s i bez infekcije MCMV-om. Dobiveni rezultati analizom na protočnom citometru pokazali su da je izražaj MHC I i m04 značajno smanjen samo na inficiranim stanicama RAW264.7 nakon tretmana otopinom EDTA 10 minuta, a razina CD80 na neinficiranim i inficiranim stanicama DC2.4 tretmanom s otopinom tripsin 10 minuta. Dobiveni rezultati ukazuju na to da je bitno na vrijeme zaustaviti djelovanje otopina tripsin i EDTA kako bi se dobili točni i pouzdani rezultati u budućim eksperimentima. Osim toga, usporedila se i razina navedenih molekula na stanicama te je pokazana veća razina MHC I i m04 na stanicama RAW264.7 i DC 2.4 što ukazuje na to da je izražaj virusom izmijenjenih MHC I na njihovoj površini vjerojatno veći nego na stanicama MEF i B12. Kakav utjecaj na imunosni sustav ima ovaj fenomen treba još ispitati.One of the first steps in the analysis of adherent cells on a flow cytometer is their detachment from the substrate and obtaining a cell suspension, however this procedure can affect the composition and integrity of the molecules expressed on the cell surface. To avoid this, we decided to examine the effect of trypsin and EDTA solutions on the expression of certain proteins, given the incubation time. Proteins whose levels were monitored are the molecules MHC I, m04 and CD80, the expression of which is influenced by murine cytomegalovirus (MCMV) to avoid recognition by immune system cells, and their regulation and expression is the subject of intensive research at the Center for Proteomics. Levels of these molecules were studied on MEF, B12, DC 2.4, and Raw264.7 cells with and without MCMV infection. The results obtained by flow cytometer analysis showed that the expression of MHC I and m04 was significantly reduced only on infected RAW264.7 cells after treatment with EDTA solution for 10 minutes, and CD80 levels on uninfected and infected DC2.4 cells after treatment with trypsin solution for 10 minutes. The obtained results indicate that it is important to stop the action of trypsin and EDTA solutions on time in order to obtain accurate and reliable results in future experiments. In addition, the level of these molecules on the cells was compared and a higher level of MHC I and m04 was shown on RAW264.7 and DC 2.4 cells, which indicates that the expression of virus altered MHC I on their surface is probably higher than on MEF and B12 cells. What effect this phenomenon has on the immune system remains to be investigated
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
