Natural food colors used in food are generally perceived as additives. Therefore, many studies have been conducted to prove the health benefits and risks of using natural food colors, which play an important role in the food industry, and to identify realistic stabilization methods. This paper aims to examine the health effects of natural food colors from a pharmacological approach.

The paper searches for relevant literature using keywords such as “natural food coloring”, “stabilization” and “antioxidant effects”. For the case study area, this paper added “food science and technology” to identify methods for stabilizing natural food coloring. From this review, the authors ultimately selected 79 articles that appeared to meet the research objectives.

When using natural food coloring in food, there are concerns about stabilization. However, with the development of food science and technology, the authors have found that there are multi-layer emulsification methods that can be applied before, during and after food manufacturing, and storage standards are also important. Natural food coloring is playing a diverse role in food science.

Natural food coloring has been reported in various types of literature to have antioxidant, anti-inflammatory and antitumor effects. The most common pigments are carotenoids. Considering the positive effects of natural food coloring on human health, the authors suggest future directions for the development of food science and technology and provide a perspective for changing consumer perceptions.

This study aims to investigate the influence of commercially available resins in water-based magenta pigment inkjet ink formulations on the properties of ink printability and the characteristics of ink application in food packaging. The impact of the resin on the jettability of the existing printability phase diagrams was also assessed.

Inks with different resin loadings were tested for selected properties, such as viscosity, particle size and surface tension. Stability was determined using a Turbiscan AGS turbidimeter and LumiFuge photocentrifuge analyzer. The ink layer fastness against abrasion and foodstuffs was evaluated using an Ugra device and according to PN-EN 646, respectively. JetXpert was used to assess Ricoh printhead jetting performance.

Printability diagrams successfully characterized the jettability of polyurethane inkjet inks on a multi-nozzle printhead and the binder improved droplet formation and printing precision.

Magenta water-based inkjet inks with commercial resins have been developed for printing on paper substrates. To the best of the authors’ knowledge, for the first time, inkjet ink stability was evaluated using the Turbiscan AGS and LumiFuge analyzers, and jettability models were verified using an industrial multi-nozzle printhead.

The purpose is to chart the negotiations on the issue of food security which was identified as a non-trade concern by the Agreement on Agriculture (AOA) and how developing Members of the World Trade Organisation (WTO) suggested that that concern should be addressed.

The history of negotiations at the WTO is examined through the lens of official documents submitted during various phases of negotiations since 1996 beginning with the Analysis and Information Exchange process to the Doha Round up to the latest Ministerial Conference in Abu Dhabi in February 2024.

The negotiations have yet to complete despite beginning over 20 years ago. The focus moved since 2008 to look at specific issues which were addressed at a number of Ministerial Conferences but the latest of these indicate that an answer can only be found in the re-negotiation of the AOA as a whole.

By focusing on official documents, the rich literature on food security has not been addressed.

The piece concludes by looking at issues which need to be resolved ahead of agreement on overall reform and suggests solutions for example in the area of safeguards and public stockholding for food security purposes.

The focus almost exclusively on official (and public) documents during the discussion is noteworthy. It also confirms that the WTO is not really that different from its predecessor - the GATT - which took nearly 50 years to reach AOA.

The coronavirus disease (COVID-19) pandemic continues to impact economic systems, with devastating consequences on livelihoods. Anecdotal evidence has predicted the adverse effects of COVID-19 on the livelihood of food system actors. Uganda experienced two lockdowns in March 2020 and June 2021 with varying government containment measures. During the first lockdown, fresh food market vending was deemed essential to meet urban food demand, and was consequently exempted from a total shutdown despite the ban on public and private transport. Thus, this study sought to examine the effect of COVID-19 containment measures on fresh food market vending businesses in Uganda.

Using primary data collected from fresh food market vendors, this study applied a pooled time-series estimation to examine the effect of the first lockdown COVID-19 containment measures on fresh food vendors' welfare.

The study revealed that COVID-19 had a significant negative impact on the income of fresh food vendors, with female vendors being the most affected. COVID-19 containment measures reduced the diversity of buyers, individual customers and the number of commodities traded in causing a greater impact on vendors' income.

The unavailability of data for vendors who did not return to the market at the time of data collection limits the scope of the study. Additionally, the absence of data for the second lockdown limited the analysis to only March 2020 lockdown period.

The empirical analysis highlights how vulnerabilities of different gender categories could be exacerbated by crises. The study provides empirical evidence of various market distortions caused by the COVID-19 pandemic and the disproportionate impact on women and men market vendors which calls for the need to integrate women's perspectives in future planning for market systems as well as advocating for gender-sensitive recovery responses.

The purpose of this study is to develop a new framework to measure waqif preference of waqf-based qardhul hassan financing in Malaysia.

Using a maqāṣid approach, this study’s data were drawn from 286 valid usable questionnaires to examine the effects of consumer, family, ummah and humanity factors on the preference.

The study found that the said factors sourced from Attia’s maqāṣid al-Shariah were instrumental in determining waqif preference to donate in waqf-based qardhul hassan financing.

Like others, this study’s findings are limited in terms of their generalisations and applications. The theory, context and variables used should be expanded in future works.

The results obtained are useful as a yardstick to enable the offered waqf-based qardhul hassan financing for improved mutual well-being among different classes of the wealth of societal groups in Malaysia. Furthermore, the results provide valuable insights into the direction for practitioners mainly managers involved in introducing waqf-based qardhul hassan financing as a new Islamic social financial instrument for poor and needy folks, at best.

This study is novel in terms of the proposed conceptual framework, where the waqif perspective comes into play.

This paper aims to explore the issue of product counterfeiting in Türkiye and assess Türkiye’s role in the global supply chain of counterfeit goods. It sheds light on the supply-side dynamics of counterfeiting in the Turkish context.

Interviews were conducted with 46 key experts, including police officers, customs officers and trademark attorneys. The study also incorporated data from a documentary analysis of counterfeit products seized by the Bulgarian Customs.

The findings of this study highlight the significant role of Türkiye in international supply chains, serving as both a manufacturing hub for a wide array of counterfeit products and a crucial transit point for goods bound for European markets. This study suggests that counterfeiting serves as a source of livelihood for many individuals in Türkiye, with counterfeiters often justifying their activities by claiming they contribute to the country’s economy through job creation and the influx of foreign currency.

While qualitative research is essential for exploring nuanced aspects and gaining in-depth insights, it may not provide the statistical robustness and generalizability associated with larger quantitative studies.

This paper is an original contribution to the understanding of product counterfeiting in Türkiye, a major counterfeit-producing country, with potential implications for the future of consumer protection and market integrity.

This study aims to empirically analyze the market response of energy companies to the Russian-Ukrainian invasion. Additionally, it examines the comparison of market reactions between companies in NATO member countries and non-member countries.

This study utilizes a sample of 1,511 energy sector companies. To achieve the research objectives, two methods are employed. First, an event study is used to analyze the market reaction using Cumulative Abnormal Return (CAR) to the announcement of Russia's invasion of Ukraine on February 24, 2022 (event day) within an event window of (−30, +30). Second, a cross-sectional analysis is conducted to compare the responses of companies in NATO member countries with those in non-member countries.

The findings of this study reveal that energy companies worldwide reacted positively both before and after the announcement of the invasion, with significant reactions observed in companies from the Americas, Europe, and Asia & Pacific regions. However, the Middle East and Africa markets did not show significant reactions. Furthermore, the study indicates that most developed and emerging markets responded positively, likely due to the increase in energy commodity prices during the war. Moreover, the market reaction of companies in NATO member countries was stronger compared to other markets.

This study contributes to the existing literature by being the first to examine the impact of the Russian invasion of Ukraine on the energy sector, while categorizing markets as developed, emerging, and frontier. It also specifically explores the market reaction of energy companies in NATO member countries, providing unique insights into the differential responses within the energy sector.

The study assesses the livelihood resilience strategies among street hawkers during COVID-19 lockdown in the Awutu Senya East Municipality in Ghana.

Using the explanatory case study approach, 12 participants (hawkers) were sampled with the aid of the purposive and convenience sampling techniques. An interview guide was used to collect data.

The study found that street hawking business, prior to the COVID-19 lockdown was a lucrative venture. The COVID-19 lockdown however had mental, psychological and economic effects on the street hawkers in ASEM causing stress, anxiety. loneliness, loss of business capital, and loss of jobs. Hawkers nevertheless demonstrated resilience in their psychological well-being by adopting strategies such as patronizing digital/social media platforms for funny content and entertainment. Hawkers also showed economic resilience through selling products on digital/social media platforms, relied on personal savings, received social support from family members and religious bodies. Government policies and interventions in the form of free water and electricity played a crucial role in building resilience of street hawkers during the COVID-19 lockdown.

The study shows that hawking is a vital avenue for entrepreneurial engagement reducing barriers to entry in formal trading, hence should be considered as key economic venture in the country’s economy. Again, the findings of the study deepen the understanding of stakeholders on the effects of COVID-19 on the psychological and economic life of street hawkers and offers insights into managing both psychosocial and financial stress during crises, emphasizing the potential benefits of resilient strategies for more effective crisis management. The study findings provide insights for government and policymakers on the experiences and coping mechanisms of the vulnerable groups and communities, particularly hawkers during the pandemic.

The study qualitatively assesses the psychological and economic effects of the COVID-19 lockdown and the livelihood resilience strategies employed by street hawkers during the COVID-19 lockdown in ASEM, Ghana.

Anchored in the theories of brand gestalt and stakeholder perspectives, this study aims to undertake a comprehensive examination of the brand gestalt concept, emphasizing its multidimensional nature and the process of co-creation.

Focused within the context of the Wonderful Indonesia brand, the research draws upon a rich qualitative data set derived from in-depth interviews conducted with 18 international tourists, supplemented by netnography (or internet ethnography) of websites, social media and online articles related to Wonderful Indonesia. Using grounded theory methodology, the qualitative data undergo rigorous analysis to identify emergent themes and patterns.

The research elucidates the four dimensions (4S) comprising brand gestalt: storyscapes, sensescapes, servicescapes and stakeholderscapes. Each dimension is further delineated into essential categories, providing a comprehensive understanding of brand gestalt. This study highlights the collaborative nature of brand gestalt, emphasizing the involvement of multiple stakeholders in shaping the brand's identity and perception. Consumer perceptions of co-creation are identified as significant contributors to brand gestalt, enhancing the brand's value proposition.

Destination management and practitioners can use the insights from the research to refine their brand management and marketing strategies by leveraging the dimensions of brand gestalt. Recognizing the collaborative construct of brand gestalt can guide businesses in fostering meaningful relationships with stakeholders and aligning branding efforts with collective visions. Understanding the role of consumer co-creation in brand development can inform strategies aimed at enhancing brand equity and fostering consumer loyalty.

This study extends existing literature on brand gestalt by providing a comprehensive examination of its four dimensions and essential categories. By emphasizing the collaborative nature of brand gestalt, this study contributes to advancing the understanding of brand co-creation paradigms. The identification of consumer perceptions of co-creation as a significant factor in brand gestalt adds novel insights to the literature, offering valuable implications for brand management and marketing strategies.

This paper aims to better understand auditing practices as a social phenomenon and management practice through a comparative historical analysis of the emergence of statutory auditing in three European countries, namely, France, Great Britain and Germany between 1844 and 1935.

The authors’ approach is a comparative history relying on a literature review, books pertaining to the period of interest and relevant archives.

The three countries’ trajectories were similar. All featured the promulgation of acts at the second half of the 19th century, the development of the accounting profession and the introduction of new acts to further strengthen statutory auditing around the Great Depression. However, each country took a different path because of the degree of regulation. For instance, the regulation strength and the degree of professionalism differed considerably by country. Business secrecy was also a departure point; it ranged from the rejection of auditors as intruders in France to Germany’s exclusively internal auditing and the UK’s peer auditing. The countries also differed on perceptions of the auditor’s role. Auditors were seen through the lens of a general interest mission in France, as advisors to internal governance bodies in Germany and as shareholders’ agents in Great Britain.

This paper compares three main European countries in the specific context of the introduction of statutory auditing. The findings of this paper are helpful for the international harmonization of auditing standards, as the derived insights provide a better understanding of the differences in the standards’ implementation.
