Positioned against prior research and relevant standards, this study is expected to advance the literature. In conclusion, it offers an investment-oriented cost–benefit assessment of the most widely deployed electrochemical energy-storage technologies, conducted within the context of a standalone storage consumer profile
Influencer Marketing and Consumer’s Lifestyle Branding: The Mediating Role of Audience Perception
No full textThis study examines how influencer marketing affects consumer lifestyle branding in Tanzania, focusing on the role that audience perception plays. The research uses Source Credibility Theory, Social Learning Theory, and Perception Theory. It collects and analyses data from a group of Tanzanian urban young people, using a quantitative method with Partial Least Squares Structural Equation Modelling (PLS-SEM). The measurement model results showed that the constructs were reliable and valid. The structural model analysis showed that influencer marketing affects audience perception (β = 0.686, p < 0.001). Perception then affects lifestyle branding (β = 0.564, p < 0.001). The mediation analysis revealed that audience perception mediates the relationship between influencer marketing and lifestyle branding (β = 0.387, p < 0.001). The model showed average explanatory power (R² = 0.471 for perception, R² = 0.318 for branding). It also showed good predictive relevance. The findings highlight the significance of genuine influencers and credibility in shaping brand identity adoption. Companies should invest in long-term influencer partnerships, create content that fits the culture, and manage perception with a plan. This study adds to the literature about digital branding in Sub-Saharan Africa and it shows that perception acts as a link between marketing influence and lifestyle alignment
Volatility Dynamics in Turkish REIT and Sectoral Indices: A Univariate GARCH Approach
No full textThis study investigates the volatility characteristics of the Turkish REIT Index (XGYO) and major sectoral indices on Borsa Istanbul, including construction, tourism, and finance, from 2014 to 2024. The analysis uses ARIMA models for the mean and univariate GARCH(1,1) models for the variance, incorporating two key macroeconomic variables: the USD/TRY exchange rate and international gold prices. These variables are selected to capture the influence of currency fluctuations and global commodity markets on sectoral volatility. The findings reveal persistent volatility across all sectors, with macroeconomic factors being a key influence. Construction and REITs are most affected by exchange rate fluctuations due to their strong connection to the real estate market, while tourism is more impacted by gold price changes, indicating greater exposure to global uncertainty. By focusing on sector-specific volatility instead of static measures, the study improves understanding of market behavior in emerging economies. It provides practical guidance for investors, portfolio managers, and policymakers, showing that while Turkish REITs can offer stability in diversified portfolios, their effectiveness depends on the macro-financial environment and sector-specific conditions

Unmasking Greenwashing: The Impact on Financial Performance and the Mediating Role of Green Reputation
No full textGreenwashing, defined as the misleading and unsubstantiated claims made by companies to appear environmentally responsible, can have multiple effects on companies. This study examines the influence of greenwashing perceptions on financial performance, with a particular focus on the mediating role of green reputation. Data were collected through a survey of 218 employees of companies listed on the Borsa Istanbul Sustainability Index. The results show that companies that engage in less greenwashing not only experience better financial performance, but also that green reputation plays a crucial mediating role in this dynamic. Companies with stronger green reputations mitigate the negative effects of greenwashing, thereby strengthening their financial performance. The study underlines that greenwashing can undermine perceptions of corporate sustainability, weaken trust and damage financial outcomes. By prioritizing authentic sustainability efforts, companies can improve their long-term financial performance and protect their green reputation, which is essential for sustainable success
Artificial Intelligence Usage by Advertising Industry Professionals
No full textTechnological developments have had a great impact on the changes experienced by the entire world since the 20th century. Rapid advances in technology and transformations brought about by digitalization have led to extensive changes in the advertising industry, as in many other sectors, especially in the last twenty years. The concept of Industry 4.0, which entered the world agenda as of 2011, and the digital transformation progressing with the technologies it encompasses, have also brought about new and various applications in the functioning of the advertising sector. While digital advertising is developing alongside traditional advertising methods, the technologies used in this field have also made rapid progress. The advertising sector and its processes are currently being shaped by digitalization and artificial intelligence, which is among the Industry 4.0 technologies. While artificial intelligence technologies enable faster, more efficient and creative results to be obtained in advertising production processes (Kietzmann et al., 2018), the approaches of professionals in the sector to this technology have also become an important area of research. The use of artificial intelligence in advertising production processes has been evaluated in different dimensions such as target audience research, advertising targeting strategies, media planning, advertising impact analysis, campaign design, copy writing and creative processes. (Qin and Jiang, 2019; Li et al., 2021). In this study, the use of artificial intelligence in advertising production processes by advertising sector professionals was investigated
Under the Belt and Road Initiative (BRI), China’s Green Investments in African Countries
No full textThe Belt and Road Initiative (BRI) has been growing its economic impact on all over the world since the declaration of Chinese President Xi Jinping in 2013. This initiative had been considered as a highly ambitious global initiative aimed at stimulating economic growth across Europe, Asia, and Africa. As of February 2025, there are 152 countries involved in the BRI initiative and a considerable number of African countries also take part in this initiative to be able to foster their economic condition along with this giant economic movement. To investigate the effects of China's BRI investments in African countries with an environmental approach, this study examines China’s green investments in African countries between 2013 and 2023, by using data from the China Global Investment Tracker, and employing descriptive statistical analysis. Focusing on 21 African BRI countries, green BRI investments from aspects of yearly trend, country distribution and sector allocation are analyzed. In the process of separating BRI investment records into green and non-green categories, it is found that green investments have grown rapidly around world over the decade, compared to non-green ones. The findings also indicate the recent years have witnessed an annual stabilization of 30% green investment. These green investments demonstrate a strategic emphasis on “resource acquisition and infrastructure building” with investments concentrated in resource-rich countries to secure essential minerals such as lithium and uranium, while simultaneously developing clean energy projects and infrastructure. Therefore, while these investments can foster sustainable development in African countries, they also pose environmental risks through mining investments, which require robust environmental assessments and governance to avoid Pollution Heaven problems
