Media in everyday life
Authors: Mulari Heta 
Published: May 2024

Back cover text

In public debate, children’s and young people’s media cultures are often addressed through a binary perspective of haopes and fears. On the one hand, children’s and young people’s digital media competences are celebrated, while on the other hand we witness many concerns about changes in children’s and young people’s everyday lives due to digital media.
This selection of articles examines the media cultures of children and young people and their mediatised daily lives. The texts are based on a collection of articles published in Finnish in 2016 called Solmukohtia: Näkökulmia lasten mediakulttuurien tutkimusmenetelmiin ja mediakasvatukseen [Turning points: Perspectives on methodologies of researching children’s media cultures and on media education, ed. Heta Mulari] and on an Opinion essay (2017) on the mediatised leisure time of children and young people writ ten by Jani Merikivi, Heta Mulari and Fanny Vilmilä.
The texts have a shared methodological perspective, and ask: How are media images and devices woven into children’s and young people’s everyday lives? What types of questions and methods can be used to approach the theme in a research-based way, together with children and young people? What types of power relations are unavoidable? Multi-method research designs that aim at children’s and young people’s experiential knowledge and participation have an important place in research of the rapidly changing world of media.

Published: May 2024

O dossiê busca aprofundar discussões e socializar estudos que articulam educação, narrativa e saúde (Souza, 2021, 2016; Souza e Souza, 2021; Souza e Delory-Mombeger, 2018), mediante processos de aprendizagens biográficas que os sujeitos constroem nas práticas cotidianas e como dispositvo de formação em educação e saúde, assim como questões de formação multipofissional em saúde, condições de trabalho e adoecimento docente. Neste sentido, este dossiê mobiliza apropriações teóricas da pesquisa (auto)biográfica como dimensão epistêmico-metodológica (Souza, 2014), através da diversidade de análise de narrativas em multiplos contextos. A noção de processos de aprendizagens biográficas e suas relações com as narrativas dos diferentes atores sociais, em uma perspectiva narrativo-biográfica, inscreve-se como terreno fértil para pensarmos processos de refiguração pessoal e profissional nos campos da saúde e da educação.
Sol–Gel Synthesis and Crystal Nucleation of Photosensitive Au/Ag- Containing Glasses of Lithium Silicate System
Authors: A. Sycheva Galina 
Published: May 2024

A sol–gel method has been proposed for obtaining the sintering mixture used in the preparing of a photosensitive Au/Ag-containing glasses of the Li2O - SiO2 system. It has been established that the use of sol–gel method for the production of the batch for synthesizing photosensitive Au/Ag-containing glasses gives more homogeneous distribution of Au/Ag metals in the bulk of the glass. Crystal-nucleation main characteristics have been defined in a large area of compounds of photo-structured compositions of a lithium-silicate system (23.4–46.0 Li2O mol % by analysis) both for spontaneous and catalyzed nucleations. The spontaneous (homogeneous) nucleation happened in the samples without any photosensitive metals and with photosensitive gold–silver additives (0.05 wt % above 100%) without irradiation; the catalyzed (heterogeneous) nucleation happened in the samples with photosensitive silver ore gold additives under x-ray CuKa irradiation. The ranges of the compositions of the glasses in which the effect of catalyzing irradiation is reversed (suppressing nucleation in accordance with the autocatalytic mechanism) under certain conditions. The spontaneous and catalyzed nucleation of crystals in the glasses of Li2O–SiO2 system caused by the addition of photosensitive impurities and X-ray irradiation was analyzed in glasses with a very wide range of compositions in Li2O–SiO2 system. Composition ranges with positive (+) and negative (-) differences in the rates of catalyzed and spontaneous steady-state nucleation were established. This finding point is favorable for obtaining photostructured (photosensitive) materials. The concentration limit was determined to be 37.98 mol % Li2O. About this value, we observe a modification of the mechanism of nucleation of crystals. The behavior of crystal nucleation in photostructured glasses under X-ray irradiation changes to the reverse: autocatalytic nucleation is suppressed rather than induced by x-ray CuKa irradiation. These peculiarities of crystallization mechanism in glasses under study give one the possibility to choose the correct composition range depending on the problems facing researchers.
Um pentecostalismo à margem
Authors: Valério Samuel Pereira 
Published: May 2024

Pentecostalism in Brazil has always raised many questions, some already answered and others still being elaborated. The Swedish Baptist Church, founded among Swedish settlers in Guarani (RS), established itself promoting a different type of Pentecostalism, therefore, this essay wants to propose some questions, in order to answer them. Are there gaps in the analysis of the beginning of Pentecostalism in Brazil? Can we use an exclusive way to understand such a fluid religiosity? Analytical exhaustion is a concern in this text, which argues that we return the tools to broaden, deepen and extend them, so that we can proceed with research on the religion that grew the most in Brazil in the 20th century. All facets already analyzed bring contributions to current research, but in some aspects it is already possible to verify exhaustion, something understandable, when there are new perspectives of observation on the phenomenon. The contribution proposed here is, based on the example of the IBS, to be careful not to close questions on this extensive, deep and plural theme.

Equity Concentration and Inefficient Investment
Authors: Xie Siyi 
Published: May 2024

Enterprise investment efficiency has been a hot topic of concern to all walks of life, and equity concentration, as an important element of corporate governance and modern enterprise construction, has attracted extensive attention from the academic community. Hence, this paper provides theoretical analyses and empirical tests on the relationship between corporate inefficient investment and equity concentration. After regression analysis, this paper finds that there is a significant negative relationship between equity concentration and the degree of inefficient investment, which confirms the hypothesis that equity concentration reduces the level of inefficient investment; compared to the company with CEO duality, in the case of equity concentration, the separation of decision-making power and decision-controlling power is more able to reduce the level of inefficient investment; However, the allocation of decision-making power does not have a significant effect on this relationship mechanism. This paper provides some theoretical basis and implications for how enterprises can optimise their shareholding structure and promote the reform of corporate governance modernisation so as to enhance investment efficiency.
Efforts to enhance self-confidence and its impact on mathematics learning: A systematic literature review
Authors: Zulfaizir  
Published: May 2024

This study aims to examine the role and efforts that can be made to improve Self-Confidence in mathematics learning. The method used is systematic literature review. The stages in this method researchers collect various scientific publications using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Based on the results of the article review, it is known that students who have high Self-Confidence in mathematics tend to have better math achievement and ability. Efforts that can be made to improve Self-Confidence are with learning strategies or models. The application of the Problem Based Learning learning model is the most widely done effort to improve students' mathematical Self-Confidence. In addition to Problem Based Learning, there are several efforts that can be made to improve students' self-confidence, among others, by applying CTL, Inquiry, Problem Solving, STAD, and MEAs learning models. Each has its own advantages and characteristics so that it can increase students' self-confidence. In addition to the learning model, the selection of learning media must also be considered in order to increase students' self-confidence in learning mathematics.

Published: May 2024

The objective of the present research is to explore the predictive association of meaning in life (presence & search) with psychological distress (depression, anxiety & stress) in people with substance use disorder. Sample of the present study comprised 200 Muslim participants (male patients with substance use disorder), ages ranging from 18 to 45 years (M =18; SD =6.55). The sample was recruited from different substance use treatment and rehabilitation centers situated in different areas of Karachi, through purposive sampling. Instruments used in this study were the Personal Information Form, Meaning in Life Questionnaire (MLQ; Stegaer, et al., 2006), and Depression Anxiety and Stress Scale (DASS; Lovibond, & Lovibond, 1995). Regression analysis shows a significant predictive relationship of meaning in life (i.e., presence & search of the meaning) with depression (adj R2=.988, F (2, 198) =8278.46, P < .0001(, anxiety (adj R2=.943, F (2, 198) =1659.82, P < .0001(, stress (adj R2=.982, F (2, 198) =5390.78, P < .0001(. Overall findings revealed that meaning in life is a significant predictor of psychological distress (i.e., depression, anxiety & stress) in people with SUD. The finding and implications are discussed in detail.

Exchange Rate Volatility and Productivity in Nigeria: An Empirical Analysis
Authors: Orisdare Monica A. , Olofin Sodik 
Published: May 2024

The volatile movement in Nigeria’s exchange rate constitutes a severe headwind to the economic activity in the country and the eventual performance of productivity and economic growth. Therefore, this study sought to investigate the impact of exchange rate volatility on productivity in Nigeria. Due to the seemingly mixed order of integration in the variables, the Johansen and Bound cointegration tests were used to establish that there are long-run relationships between the variables. Following the cointegration tests, the analysis of the study was based on the Autoregressive Distributed Lag (ARDL) Model. The findings from the study revealed that exchange rate volatility negatively impacts productivity in Nigeria in the short run and in the long run. However, the financial development in Nigeria negatively impacts productivity, reflecting the underdevelopment of the financial system to transmit its function to the real sector. Other variables considered emphasise persistence in the way they impact productivity. The article also emphasised the need for the harmonisation of foreign exchange management guidelines and clarity and transparency in the management of the foreign exchange market.
