Effect of enzymatic pretreatment on the extraction yield and physicochemical properties of sago starch

Abstract: The aim of this research was to investigate the extraction yield and physicochemical properties of sago starch extracted after enzymatic pretreatment. Sago pith was enzymatic-pretreated by varying enzyme (cellulase enzyme complex) concentration, pretreatment time, and sago pith slurry concentration. The extracted sago starch was analyzed for its properties, e.g., extraction yield, pasting and thermal properties, and in vitro starch digestibility. Sago pith contained 82% (db) starch. The extraction yield and reducing sugar released increased with enzyme concentration and pretreatment time. The optimum enzymatic pretreatment conditions were 10% (w/w) sago pith slurry, enzyme concentration of 0.25 mL (618 carboxymethylcellulose unit and 139 p-nitrophenyl-β-d-glucopyranoside unit)/g substrate, and 24 h pretreatment time, providing the highest extraction yield of 71.36% (w/w sago pith, db), while control method, without enzymatic pretreatment, provided 61.01% extraction yield. Results from pasting and thermal properties confirmed that the granular stability, resistance to shear, and crystalline perfection of sago starch were improved due to hydrothermal effect of annealing during enzymatic pretreatment. The enzymatic-pretreated sago starch also had lower retrogradation but higher starch digestibility than the control sago starch. The enzymatic pretreatment enhanced the extraction yield of sago starch and also improved its quality by the effect of annealing.

Students’ expectations, experiences, and career direction after in-house internship: the pedagogical role of the hotel training center in Thailand

Abstract: This study investigates the in-house internship of the hotel training center in Thailand, with two specific objectives: (1) to investigate the expectation of students prior to taking internship and compare it with their perception after taking the internship and (2) to explore experiences and skills gained by student interns and the influence of in-house internship on students’ choice of job after graduation. This study employs a qualitative methodology through content analysis to extract meaning from the students’ opinions derived from the focus group interview and the narrative writing of the short open-ended questions. The results from the study demonstrate the crucial role of compulsory in-house internship within the Tourism and Hospitality Management curriculum. The study also confirms that in-house internship can equip and prepare students for the real internship experience within the hotel industry and it also sheds light on the pedagogical role of the in-house internship in the tourism and...

The Quality and Readability of English Wikipedia Anatomy Articles

Abstract: Forty anatomy articles were sampled from English Wikipedia and assessed quantitatively and qualitatively. Quantitatively, each article’s edit history was analyzed by Wikipedia X-tools, references and media were counted manually, and two readability indices were used to evaluate article readability. This analysis revealed that each article was updated 8.3 ± 6.8 times per month, and referenced with 33.5 ± 24.3 sources, such as journal articles and textbooks. Each article contained on average 14.0 ± 7.6 media items. The readability indices including: (1) Flesch–Kincaid Grade Level Readability Test and (2) Flesch Reading Ease Readability Formula demonstrated that the articles had low readability and were more appropriate for college students and above. Qualitatively, the sampled articles were evaluated by experts using a modified DISCERN survey. According to the modified DISCERN, 13 articles (32.5%), 24 articles (60%), 3 articles (7.5%), were rated as “good,” “moderate,” and “poor,” respectively. There were positive correlations between the DISCERN score and the number of edits (r = 0.537), number of editors (r = 0.560), and article length (r = 0.536). Strengths reported by the panel included completeness and coverage in 11 articles (27.5%), anatomical details in 10 articles (25%), and clinical details in 5 articles (12.5%). The panel also noted areas which could be improved, such as providing missing information in 28 articles (70%), inaccuracies in 10 articles (25%), and lack or poor use of images in 17 articles (42.5%). In conclusion, this study revealed that many Wikipedia anatomy articles were difficult to read. Each article’s quality was dependent on edit frequency and article length. Learners and students should be cautious when using Wikipedia articles for anatomy education due to these limitations.

Exploring the Agency Cost of Debt: Evidence from the ISS Governance Standards

Abstract: Corporate governance is usually viewed in the context of strengthening shareholder rights and enhancing shareholders’ welfare. However, the impact of corporate governance on bondholders is much less understood. We explore how corporate governance influences the cost of debt financing. Using broad governance metrics encompassing fifty governance attributes reported by The Institutional Shareholder Services (ISS), we document that stronger corporate governance is associated with a higher cost of debt. As governance strengthens by one standard deviation, the cost of debt rises by as much as 11%. The results are robust even after controlling for both firm-specific and issue-specific characteristics. Our results are important because they suggest that corporate governance has a palpable effect on critical corporate outcomes such as credit ratings and bond yields. More importantly, we show that, while corporate governance may mitigate the agency conflict between managers and shareholders, it appears to exacerbate the agency conflict between shareholders and bondholders (the agency cost of debt).
