Experimental and numerical analysis of sodium-carbonate salt gradient solar-pond performance under simulated solar-radiation

The objective of this study is to investigate experimentally and theoretically whether sodium carbonate (Na2CO3) salt is suitable for establishing a salinity gradient in a salt-gradient solar-pond (SGSP). For this purpose, a small-scale prismatic solar-pond was constructed. Experiments were conducted in the laboratory under the incident radiation from two halogen-lamps acting as a solar simulator. Furthermore, a one-dimensional transient mathematical model that describes the heat and mass transfer behaviour of the SGSP was developed. The differential equations obtained were solved numerically using a finite-difference method. It was found from the experiments that the density gradient, achieved using sodium carbonate salt, can suppress convection from the bottom to the surface of the pond. © 2005 Elsevier Ltd.

Artificial Intelligence and Cultural Production in Public Policies: Discussion of Examples from International Public Policies

The creative economy is defined as a new economic activity area subject to global competition. However, the relationship between artificial intelligence (AI) and cultural production, as a relatively new technology, has been underrepresented in Western literature and policies. This study discusses the context of AI and Generative Artificial Intelligence (GAI) policies in relation to their cultural and societal implications. Departing from previous studies suggesting that algorithms managed by platforms inadequately encompass cultural authenticity, AI is here considered as a domain containing cultural risks. This study aims to reveal the disadvantages of the Global South by discussing the concerns of exclusion and bias of AI through the public policy texts of developed countries and to contribute to the public policy development process of Turkey in relation to the field of culture. To this end, policy texts on AI and GAI from the eight OECD countries investing the most in AI, the European Union, Japan and Saudi Arabia have been analyzed. Through policy framing analysis, the roles of cultural institutions in policy-making, the framing of bias and cultural diversity themes in the texts, and how policy interventions in the AI field are framed have been examined. In light of the findings that AI is implicitly positioned as a new area of colonialism in developed countries policy documents, a perspective sensitive to cultural policies is proposed for Turkey to produce an inclusive AI policy based on her public administration tradition and technology infrastructure investments

Sailing Against The Wind: Studying Platformization in The Music Industry in Turkey

ÖZET: Bu çalışmada Türkiye’de müzik endüstrisinde platformlaşma olgusunun endüstrinin farklı aktörleri tarafından nasıl kavrandığını, araştırmamızın hikâyesini, sorularımızı, saha hazırlığımızı, saha deneyimimizi, araştırmayı nerede ve kimlerle nasıl paylaştığımızı anlatıyoruz. Bir araştırmaya düşünümsel bakış denemesi olan bu hikâyelendirmenin, yaratıcı endüstrileri ve özellikle müzik endüstrini kültürel ekonomi politik ve kültür politikası kesişiminde tartışmada yeni araştırmalar için zihin açıcı olabileceğini düşünüyoruz. Araştırmacı olarak bu süreçte öğrendiklerimiz bizi de yaratıcı endüstri ve kültür politikaları çalışmaları için yeni sorulara ve olgulara yönlendirdi.ABSTRACT: In this study, we describe how the phenomenon of platformization in the music industry in Turkey is understood by different actors of the industry, the story of our research, our questions, our field preparation, our field experience, where and with whom we shared the research. This storytelling is an attempt at a reflexive approach to research, and it can be an eye-opener for new researches in discussing the creative industries, especially the music industry, at the intersection of cultural political economy and cultural policy. As a researcher, what we have learned in this process has also led us to new questions and phenomena for creative industry and cultural policy studies

The Native Symbols Engaging Turkish Players to Digital Games in a Playability Perspective

Background. The satisfaction of a player's gaming experience has a great impact on their game preferences. The goal of this study was to investigate the opinions and experiences of Turkish players of computer games in order to examine the effects of native symbols on their game preferences
