Abstract
Purpose
The purpose of this paper is to encapsulate vanilla extract by using inclusion complex of ß-cyclodextrin and also to investigate the qualities of the encapsulated powder in terms of vanillin content, moisture content, and stability under accelerated condition.
Design/methodology/approach
A randomized block and factorial 3×3 experimental designs with three replications were used for the studies of solvent extraction, microencapsulation of natural vanilla extract and stability of microencapsulated vanilla powder.
Findings
Ethanol concentration and ratio of vanilla to ethanol had positive effects on vanillin content. The extraction with 55 percent ethanol and the ratio of vanilla pods to ethanol as 1:4 provided the highest vanillin content of 341.23 mg/100 mL of the extract. The amount of vanilla extract and kneading time gave significant (p<0.05) effect on the microencapsulation efficiency (ME). The greatest ME found was 94.50 percent when 9 percent vanilla extract and 10 min of kneading time were used. The interaction of temperature and water activity gave significant effect on the second-order kinetic reaction of encapsulated vanilla powder (p<0.05).The most suitable condition of storage was 35°C with aw of 0.64, providing the kinetic constant (k) of 0.0024, and correlation coefficient (R2) of 0.92 with thalf-life of 4.54 weeks.
Originality/value
This study provides the most suitable condition for natural vanilla extraction and microencapsulation as well as storage stability for natural vanilla powder production using the third grade vanilla pods grown at Royal Project, Khun Wang Center, Chiang Mai, Thailand.

Abstract
This chapter examines ways the Spanish Constitution of 1812, also known as the Constitution of Cádiz, has been viewed in historical and constitutional thought. The document is a liberal constitution establishing constitutional rights, a representative government, and a parliamentary monarchy. It influenced ideas of American equality within the Spanish Empire, and its traces are observed in the process of Latin American independence. To these accepted views, one must add that the Constitution was a lost moment in Latin American constitutional development. By the immediate politicization of constitutionalism after 1812, the document marks the beginning of constitutional difficulties in the region.

Abstract
Purpose
In this work, the authors are interested in the notion of vector valued and set valued Pettis integrable pramarts. The notion of pramart is more general than that of martingale. Every martingale is a pramart, but the converse is not generally true.
Design/methodology/approach
In this work, the authors present several properties and convergence theorems for Pettis integrable pramarts with convex weakly compact values in a separable Banach space.
Findings
The existence of the conditional expectation of Pettis integrable mutifunctions indexed by bounded stopping times is provided. The authors prove the almost sure convergence in Mosco and linear topologies of Pettis integrable pramarts with values in (cwk(E)) the family of convex weakly compact subsets of a separable Banach space.
Originality/value
The purpose of the present paper is to present new properties and various new convergence results for convex weakly compact valued Pettis integrable pramarts in Banach space.

Abstract
EACH blade of an airscrew is submitted to an elementary static balance check after it has been completed. But this operation does not eliminate the necessity to carry out a general balance of the complete airscrew. This is carried out statically, first of all for the hub alone, and then statically and dynamically for the completely assembled airscrew.

Abstract
Drawing on research in the worlds of advertising, magazines and fashion, this paper discusses how celebrities mediate between different fields of cultural production. By focusing on celebrity endorsements in advertising, it also outlines how film actors and actresses, athletes, models, pop singers, sportsmen and women mediate between producers and consumers via the products and services that they endorse. As economic mediators, celebrities’ actions have important strategic and financial implications for the corporations whose products they endorse. As cultural mediators, they give commodities personalities and perform across different media, linking different cultural fields into an integrated name economy.

Abstract
Purpose
The goal of this chapter is to discuss the foundations of ‘modern finance’, its paradigm and conceptual framework, its methods and tools, its practices and results, its governance and regulation.
Approach
The first part presents the characteristics of ‘modern finance’ and its negative effects. The second part analyses the efforts made to remedy those effects and argue about the need for a real reform.
Findings
Several aspects are pointed, for example an unreasonable ‘normality’, incentives that encourage excess, the spread of subprime crisis, etc. The contemporary finance is a ‘giant with clay feet’.
Originality/value
We need to proceed with a dual reembeddedness of finance in the economy and economy in society.

Abstract
This chapter focuses on information efficiency as provided by fair value accounting (FVA) and corporate governance (CG) practices in an emerging market. Positive accounting theory was adopted as an empirical model to test the relationship between information efficiency and stock prices. Data for the period 2007–2020 from 576 listed firms on the Stock Exchange of Thailand were collected, tested, and analyzed using a fixed effect estimator. The results indicate that investors in the stock market trust the use of publicized efficient information as provided by FVA and CG practices in making their investment decisions, when FVA and CG proxies were found to significantly influence stock prices. Hence, this evidence implies that information efficiency leads to better firm values in an emerging market.

Abstract
Purpose
The purpose of this paper is to analyse the role of value added (VA) as an indicator of intellectual capital (IC), and its impact on the firm's economic, financial and stock market performance.
Design/methodology/approach
The value added intellectual coefficient (VAIC™) method is used on 300 UK companies divided into three groups of industries: high‐tech, traditional and services. Data require to calculate VAIC™ method are obtained from the “Value Added Scoreboard” provided by the UK Department of Trade and Industry (DTI). Empirical analysis is conducted using correlation and linear multiple regression analysis.
Findings
The results show that companies' IC has a positive impact on economic and financial performance. However, the association between IC and stock market performance is only significant for high‐tech industries. The results also indicate that capital employed remains a major determinant of financial and stock market performance although it has a negative impact on economic performance.
Practical implications
The VAIC™ method could be an important tool for many decision makers to integrate IC in their decision process.
Originality/value
This is the first research which has used the data on VA recently calculated and published by the UK DTI in the “Value Added Scoreboard”. This paper constitutes therefore a kind of validation of the ministry data.

Abstract
Purpose
This study assesses the extent to which integrated extension services contribute to the adoption of climate-smart agriculture (CSA) innovations within the cotton value chain in Burkina Faso.
Design/methodology/approach
To address the research question, a probit multivariate econometric model with sample selection is utilized. The model is applied to a random sample of farmers (n = 510), and the endogeneity is addressed through a control function approach.
Findings
The study highlights the central role of value chains, particularly in the cotton sector, in overcoming resource scarcity through integrated extension services. Findings show that smallholder farmers who benefit from sound extension services are more willing to adopt and diversify CSA technologies. These include improved seeds, conservation techniques, adapted planting dates and mechanization. This study confirms the synergistic nature of these technologies and emphasizes that effective climate risk mitigation depends on the combined adoption of CSA technologies.
Research limitations/implications
The use of cross-sectional data limits the analysis of long-term farmer behavior, and due to data limitations, the focus was primarily on the contributions of cotton companies and farmers to climate risk mitigation. Future research using panel data across the value chain could provide a more robust insights for policy decision-making.
Originality/value
The study contributes to the existing body of knowledge by emphasizing the crucial role of integrated extension services within the cotton value chain in developing countries. This highlights the critical benefits for farmers and emphasizes the need to diversify modern technologies to effectively combat climate change and its variability in agriculture.
