Artemia salina lethality and histopathological studies of Siam weed, Chromolaena odorata.

Abstract: Siam weed, Chromolaena odorata , leaves, stem, and root were extracted with aqueous and ethanol solvents within 1, 3, 5 and 24 hours. The extractions were determined amount of total phenolic compound using Folin-Ciocalteu reagent. The extract that showed the highest amount of total phenolic compound was used for evaluating the cytotoxicity test against Artemia salina at varying concentrations as 0, 50, 500, 5,000 and 50,000 ppm. The cytotoxicity data were determined the median and 90% lethal concentration, LC 50 and LC 90 , respectively, within 24 hours. The result revealed that the highest amount of total phenolic compound was 198.02+3.96 mg of gallic acid equivalent per gram of aqueous leaf extraction in 24 h. Therefore, the 24-hour aqueous extract of C. odorata leaf expressed the 24-h LC 50 and LC 90 values in A. salina were 43, 551 and 78,391 ppm, respectively. The lesions were observed in intestinal parts such as edema, deformation or elongation of the enterocytes, blebbing cells, and pyknotic cells.

Did Firms Manage Earnings More Aggressively during the Financial Crisis

Abstract: We investigate the extent of earnings management during the financial crisis of 2008 (The Great Recession). Based on a large sample of over 14,000 observations across 15 years, our results show that firms managed earnings less aggressively during the crisis. We also show a severe decline in firm value and profitability during the crisis. Our results are consistent with the notion that, during the crisis, firm performance was so far below the target that no amount of earnings management would have been sufficient to reverse the poor earnings picture. As a result, managers were less motivated to manage earnings. Furthermore, the crisis serves as a convenient excuse for poor performance, lessening the motivation and necessity for managers to manage earnings. Additional analysis including fixed-effects regressions, propensity score matching, and GMM dynamic panel data estimation, shows that our results are robust and are not driven by unobserved heterogeneity. Further analysis documents similar findings for the Dot-com crisis in 2001 and the Asian Financial Crisis in 1997-1998.

Simulacra, Simulation, and the Internationalization of Higher Education in Thailand

Abstract: This paper offers a discourse analysis and critique of the processes of internationalizing education in the case of a university international college. The critique is rooted in Jean Baudrillard’s work of simulation and simulacra. This paper offers a seminal audit of how simulation and simulacra has informed organizational theory literature, and how it may be applied for understanding the symbolic value of international colleges in Thailand, but more specifically in Bangkok. Through this review, the author works to make the claim that the case international college has become a symbol of elitism in its context, and it has ceased any connection to the humanistic and cosmopolitan values that an international education espouses in education literature. It is argued that the case international education has achieved full simulacra. This critique leads to a conceptual framework that may be put to use to inspire critical research about the symbolic value of international education in Thailand.

Prevalence and cluster effect of self-reported allergic reactions among insect consumers.

Abstract: Background Entomophagy is a common practice in many parts of the world. Allergic symptoms after insect consumption have been reported in healthcare literature and in the news. Objective We evaluated prevalence and association of allergic history and self-reported allergic reactions after entomophagy. Methods We conducted a cross sectional internet-based survey. Participants were people who have consumed insects. Collected information included demographic data, the practice of entomophagy, allergic history and self-reported allergic symptoms. Results During May to October 2017, 140 people completed the survey. Median and range of age are 27 and 18-64 years. Ninety-two (65.7%) were female. Thirty-seven (26.4%) and 13 (9.3%) participants had history of allergy and seafood allergy, respectively. Eighteen (12.9%; 95% confidence intervals (CI) 7.3-18.4) participants reported allergic reactions after insect consumption. Nine symptomatic participants reported other people who partook insects to have allergic symptoms. Reported factors with significant association with allergic reactions were history of allergy and seafood allergy with prevalence ratios of 4.83 (CI 1.83-10.44) and 3.76 (CI 1.59-8.87), respectively. Conclusions The prevalence of self-reported allergic reactions after entomophagy is 12.9%. Clusters of people with post-entomophagy allergic symptoms are found. History of allergy and seafood allergy are associated with post-entomophagy allergic reactions.
