It is important to analyze the resulting carbon footprint to determine the extent of its impact, especially on the environment and its contribution to the greenhouse gas (GHG) effect, so that appropriate emission reduction measures can be identified. The method used is a literature study by collecting secondary data from the previous research existed in Indonesia. The average amount of carbon footprints are produced by Indonesia from fossil power plants (Coal, Natural Gas, and Diesel Fuel) in the last 5 years is 5538.11 KgCO2/MWh. The potential demand for electricity and the emissions resulted by-products will continue to increase every year, so solutions are needed best way to reduce emissions. Emission reduction can be resolved by increasing the use of New and Renewable Energy (NRE) as a raw material for Diesel Power Plants (DPT). The type of EBT used is biodiesel from palm oil. The carbon footprint of palm oil biodiesel production process is only 2281.66 KgCO2/MWh.  41% lower than that of fossil power plants. The push for NRE development needs to be further increased in order to reduce energy emissions and to achieve the target of using New and Renewable Energy (NRE) of at least 23% and 31% in 2025 and 2050. The type of EBT used is biodiesel from palm oil. The carbon footprint of palm oil biodiesel production process is only 2281.66 KgCO2/MWh.  41% lower than that of fossil power plants.

The present study aimed to examine the relationship between parenting styles with anxious thoughts of the students in selected high schools of Mashhad, Iran. A quantitative methodology in form of a correlational design was employed in this research, which comprised two main variables including parenting styles and Iranian teenagers’ anxious thoughts. To address the research objective, 180 teenagers who were students at some schools in Mashhad, Iran, and their parents, completed the study questionnaires which included Baumarind parenting styles Scale (1971) and the Anxious Thoughts Inventory (AnTI) designed by Wells (1994). The analysis of the data obtained from implementing the questionnaires was performed through SPSS25 software in two sections: descriptive and inferential (Pearson Correlation Coefficient and regression analysis, i.e. ANOVA). The results showed that there was a significant relationship between anxious thoughts and the three parenting styles. Also, the relationship between the authoritarian parenting style and the symptoms of anxious thoughts (r = -0.731) is significant in a negative way. On the other hand, it is observed that there is a positive correlation between authoritarian parenting style and anxious thoughts (r = 0.511). Finally, it is seen that there is a positive correlation between permissive parenting style and anxious thoughts (0.461), (p</01). It can be concluded that parenting styles can strongly predict anxious thoughts and determine 0.544 of variances of the anxious thoughts.

Esta pesquisa embasa-se teoricamente nos seguintes autores: Bacha (2014), Bamberger (2002), Diniz e Silva (2015), Freire (1996, 2008), Girotto (2015), Grossi (2013), Indursky e Zinn (1985), Kramer (2013), Lajolo (2011), Linard (2016), Ruiz (2002), Rezende (2013), Silva (2005, 2015), Soares (2016), Solé (1998), Zulim (2015), entre outros. Tal pesquisa surgiu da necessidade de refletir sobre a importância da leitura para o desenvolvimento do aluno e como o hábito de ler ainda é deficiente na educação pública do Brasil. Por ter um vasto número de autores que abordam acerca desse assunto, este estudo pode ser complementado e estendido a longo prazo, com mais embasamento teórico.

Este artigo apresenta uma síntese dos conceitos da Produção mais limpa com a finalidade de identificar suas práticas, descrever os modos de aplicação e benefícios da P+L em empresas de pequeno porte, a fim de diferenciar estas empresas e torná-las competitivas. A partir de pesquisas bibliográficas, a sustentabilidade abordada pela P+L consiste em um pensamento estratégico para redução de resíduos na fonte, diminuindo também os custos de produção. Diferentemente do que se costuma visualizar nas empresas atualmente, onde as práticas ambientais são os tratamentos dos resíduos já gerados. A avaliação teórica dos resultados propostos neste artigo, a partir do estudo da P+L, garante redução nos custos e redução da geração de resíduos (lixo) a níveis mais baixos que as demais práticas sustentáveis. As barreiras da implementação da P+L, em pequenas empresas, são descritas de forma a antecipar as possíveis dificuldades, buscando comprovar que, superadas tais barreiras, as empresas podem ter resultados positivos e benéficos.

Objective: This research aims to provide proposals for a comprehensive policy framework and strategic plan to advance economic prosperity through infrastructure development in the New Capital Region of East Kalimantan, Indonesia.
 
Theoretical Framework: The theory used is crowdfunding from Kirby & Worner (2014). The crowdfunding model includes social crowdfunding communities, loans/donations, and reward crowdfunding. The financial benefits of crowdfunding encompass peer-to-peer (P2P) loans and equity crowdfunding.
 
Method: The method employed is a qualitative approach using interview discussions supported by participant observation. Twenty-two stakeholders, including policymakers and community members, participated in the study, providing diverse perspectives. The research takes place from September 16 to November 19, 2023, with the research locus in the city of IKN Nusantara.
Results and Conclusions: To comprehend the short-medium-and long-term perspectives, these plans require innovative financing methodologies, such as crowdfunding, which is considered an essential element. In the short term, community involvement is targeted through SBSN, facilitating direct community participation in infrastructure funding. This medium-term strategy integrates digital platforms and blockchain technology, increasing transparency and strengthening public trust. A mixed creative financing model is recommended for public transport, aligning crowdfunding with Public-Private Partnerships. In the long term, this study highlights the growing maturity of crowdfunding and its potential positive influence on the infrastructure supporting the economy, setting a precedent that can be imitated in other regions in Indonesia.
 
Research Implications: In line with national aspirations to achieve advanced status by 2045, this proposal supports inclusive economic growth inspired by China's expertise in optimizing domestic resources. The importance of the Open Government concept was underlined, emphasizing community involvement to reduce foreign dependence and encourage sustainable economic growth.
 
Originality/Value: This research includes concrete actions, such as implementing Government Sharia Securities, blockchain integration, and targeted financial education campaigns, all aimed at ensuring the effectiveness and long-term success of infrastructure development in the Capital Region.

Published: March 2024

The results of palynological analysis allowed climatostratigraphic subdivision of Pleistocene deposits of the Trlica cave, located in the vicinity of Pljevlja town in northern Montenegro. The palynological record confirms significant hiatuses in the sedimentation revealed by the field lithologic-genetic analysis. The changes of landscape and climatic conditions that occurred during the formation of the studied Pleistocene strata are reconstructed. Specific features of flora and vegetation of three stages of the final part of the Early Pleistocene corresponding to MIS 22, MIS 21, MIS 20, as well as three stages of the first half of the Middle Pleistocene correlated to MIS 19, MIS 18 and MIS 15, have been identified. Throughout the entire period of the Pleistocene deposits in Trlica, the mountain landscapes in the vicinity of the cave were covered mainly by forests, that underwent significant transformations of their composition during the change of interglacial conditions by the stages of cooling. The materials of palynological analysis of the Quaternary sediments of Montenegro are very scarce. Therefore, the sporepollen data of the Trlica section and the revealed climatic-phytocenotic successions of three interglacial and three relatively cold (near-glacial) stages of the Early and Middle Pleistocene presented in the article are an important contribution to the study of the Pleistocene paleoenvironments of the Balkan Peninsula.
VIDEO GAME DEVELOPMENT FEATURES AND ASSESSMENT OF THEIR IMPACT ON LOCALIZATION
Authors: Arishchenko Stanislav I.
Published: March 2024

The problem of inconsistency of the scenario and other soft- and hardware aspects of various digital entertainment products is becoming more and more popular among the scholars from various scientific areas. The main aim of this paper is analyzing the localization issues of mass-media products as well as videogame localization. The quality of an in-game experience of a localized videogame depends on a variety of factors and the most significant of them are the so-called gameplay issues. Under the term “gameplay issues” gamers and researchers often understand the features of videogame development. Facing these features could trigger different emotional reactions among the players. As a material for this paper several in-game textual materials have been chosen, viz.: Final Fantasy Chrystal Chronicles, Spider-Man and GTA: San Andreas. As the research has shown, the most usable and suitable technique for neutralizing the negative influence to the gamers caused by gameplay issues is the correction of the videogame scenario. Thus developers and localization specialists can minimize all negative influence in a fast and cheap way. However, scenario correction is not the only technique used during the development and localization processes of a videogame’s lifecycle. Here could also be mentioned another way to avoid negative emotional reactions: intersemiotical transferring. By using the toolkit of 3D visualization software a wide variety of gameplay issues could be neutralized. This technique shows itself at its best when it comes to censorship issues. In conclusion, several ways of neutralizing the negative effect of the gameplay issues have been discovered and formulated. The materials and examples mentioned in this paper could be applied in the industrial practice of the digital media localization specialists as well as used by beginners in the field of localization. Moreover, this paper could be of help to students looking for scientific information about the highly specialized translation practices.
