Abstract
Purpose
This paper seeks to demonstrate a functional beverage incorporating pine bark which is an unutilized forestry waste, determine in vitro release kinetics of enriched beverages, and antioxidant activities, besides assessing their shelf stabilities.
Design/methodology/approach
Orange juice was enriched with Pinus brutia, Pinus pinea bark extracts, Pycnogenol®. In vitro release kinetics was determined in pH 1.2 and pH 7.4. Ascorbic acid content, pH, titratable acidity, and colorimetric analyses were analyzed monthly for eight months to determine shelf life. Additionally, total phenol contents and radical scavenging activities were analyzed. Subsequently a consumer acceptance test was conducted among 200 participants.
Findings
The release of all extracts in orange juices in pH 1.2 were slower than pH 7.4. The release results were fitted to Higuchi square root of time kinetic model with high determination coefficients. Although total titratable acidity values were in agreement with the trend of minor pH changes, prominent losses in antioxidant capacities, ascorbic acid contents and color were observed for the last two months suggesting a shelf life of six months. Female participants and young people had a greater tendency to consume such a beverage. Health concerns and flavor were the primary factors affecting their purchasing decisions.
Research limitations/implications
Findings of the study demonstrated the effects of fortification with a plant‐based extract as a substitute to the present practice of fortifying beverages with vitamins and minerals for a potential future market.
Originality/value
The paper shows that juices fortified with pine bark extracts show higher antioxidant capacities and ascorbic acid contents compared to the control, thereby providing improved functionality.

Abstract
Since 2004, Turkish cinema has been witnessing an emergence of horror genre, now flooded with stories of possession by malevolent jinn, as transgressive, volatile figures of abjection. These female-centred narratives rely both on Islamic cosmology and myths and folktales of pre-Islamic Anatolian oral culture. The chapter will first explore the reasons horror has been neglected in the century-long history of cinema in Turkey and move on to highlight the socio-economic, cultural, and political contexts that were catalysts for the horror genre’s emergence. Then, the chapter will discuss the codes and conventions of the genre and explore the unique place of Alper Mestçi’s 2007 film Haunted (Musallat), among its contemporaries in terms of the ways in which the film challenges these established codes and conventions. In analysing Haunted, the chapter will use the theoretical framework of Barbara Creed, Carol J. Clover and Julia Kristeva to discuss the monstrous-feminine and masculinity as abjection.

Abstract
Purpose
This study investigates the different environments in which high school students go through in their formative years and whether these environments affect their intention to study entrepreneurship as a career choice. Bronfenbrenner's social-ecological theory has been used as a backdrop to capture these environments. Four variables chosen are family support, school environment, self-efficacy and global awareness.
Design/methodology/approach
A sample of 1770 high school students were chosen through simple random sampling within Gujarat state. Structural equation modeling (SEM) was used to predict the overall effect of all the environments on Entrepreneurship Education Intention (EEI) of these students.
Findings
Findings reveal that self-efficacy has the most substantial influence on intentions. Family support and global awareness have a combined significant effect on self-efficacy, which further translates to a significant impact on high school students' intentions. School environment has an effect on global awareness, which in turn has a negative effect on students' willingness to study entrepreneurship in India.
Research limitations/implications
The study has implications in curriculum design and theory development. The study also provides schools with a framework to understand how to orient their students toward entrepreneurship.
Originality/value
This paper uses a novel theory that has not been applied in studies related to entrepreneurship education and proposes a model for the same. This novelty also reflects in our findings which have subsequent implications for theory and practice.
