The Case Method for Teaching Philosophy

Based on an examination of specific limits in philosophy education when professors employ presentation and question-and-answer methods, the article emphasizes the necessity to reinvent philosophy teaching methods in order to promote active and creative pupils. Among active teaching approaches, the article chose the case method to supplement the traditional teaching method, which has frequently occupied a unique position in teaching philosophy up to now.&nbsp

On signalling and debt maturity choice

The theoretical literature on a firm?s choice of debt maturity argues that a borrowing firm can signal its value in asymmetric information setting by borrowing short. This well-known fact is based on Flannery (1986). This paper questions the use of debt maturity as a signalling device. We demonstrate that Flannery?s (1986) signalling outcome is vulnerable on two accounts. First, the separating equilibrium established by Flannery is not driven by the incentive compatibility. Second, derivations of the separating equilibrium appear to be vulnerable due to the lack of the refinements of pooling equilibria. If correct constraints are provided, the parameter space for the separating equilibrium shrinks, moderating the signalling role of debt maturity.

Collateral and Debt Maturity Choice. A Signaling Model

This paper derives optimal loan policies under asymmetric information where banks offer loan contracts of long and short duration, backed or unbacked with collateral. The main novelty of the paper is that it analyzes a setting in which high quality firms use collateral as a complementary device along with debt maturity to signal their superiority. The least-cost signaling equilibrium depends on the relative costs of the signaling devices, the difference in firm quality and the proportion of good firms in the market. Model simulations suggest a non-monotonic relationship between firm quality and debt maturity, in which high quality firms have both long-term secured debt and short-term secured or non-secured debt.

Užívání anglických jmen vietnamskými univerzitními studenty

and keywords The aim of this thesis is to investigate the management of personal names of Vietnamese students living and/or studying in the United Kingdom. It explores reasons for adopting English names, situations for different name usage, and motivations behind name choices. The data were obtained both quantitatively through a questionnaire and qualitatively through one-on-one interviews. The results confirm that management of personal names heavily depends on the individual. However, certain patterns can be observed. The study's findings demonstrate that participants use strategies for selecting an English name that align with those proposed in previous works by Burt (2009), Chen (2015), and McPherron (2009). Additionally, the research corroborates the role of convenience as a significant factor influencing individuals to adopt an English name as proposed by previous research. However, the study also identifies deviations from existing literature. Notably, the trendiness of having an English name appears to hold less importance for the participants, differing from the findings of Barešová & Pikhart (2020). Furthermore, contrary to the perspectives of Chen (2015) and Heffernan (2010), the research indicates that adopting an English name for use in English classes does not significantly impact the...a klíčová slova Cílem této práce je prozkoumat management osobních jmen vietnamských studentů žijících a/nebo studujících ve Spojeném království. Aspekty řešené v této práci jsou důvody pro přijetí anglického jména, v jaké situaci používá jedinec které jméno a jaké jsou motivace při výběru anglického jména. Data byla získána kvantitativně pomocí dotazníku a kvalitativně prostřednictvím rozhovorů. Výsledky potvrzují, že management osobních jmen silně závisí na jednotlivci, lze však identifikovat určité vzorce a trendy. Výsledky této studie naznačují, že účastníci uplatňují stejné strategie při výběru anglických jmen, které jsou konzistentní s předchozími pracemi, například Burt (2009), Chen (2015) a McPherron (2009). Kromě toho tato studie potvrzuje, že usnadnění každodenního života hraje významnou roli při rozhodování jednotlivců přijmout anglické jméno, jak bylo identifikováno v předchozím výzkumu. Zároveň však tato studie identifikuje odchylky od existující literatury. Zdá se, že trendovost anglických jmen má pro účastníky menší význam, což se liší od závěrů Barešové a Pikharta (2020). Navíc, na rozdíl od závěrů Chena (2015) a Heffernana (2010), tato studie ukazuje, že používání anglického jména specificky během hodin angličtiny nemá významný vliv na celkové užívání anglického jména.

Factors Influencing Adoption of Online Payment via E-Commerce Platforms

In this study, the research group applied the Technology Acceptance Model (TAM) by Davis (1989) to analyze factors influencing customers’ intention to use the online payment via e-commerce platforms as well as to encourage Vietnamese consumers to adapt this means of payment. Besides Perceived Ease of Use and Perceived Usefulness in the original model of Davis (1989), three additional dependent factors (Subjective Norm, Trust, Risk) were added to the model. The new model proposed by the research group aims to give a more well-rounded explanation on Vietnamese consumers’ attitude and intention towards the online payment. Using sample data including 448 consumers in the Northern region of Vietnam, the research group has been able to validate the hypothesis model and prove that independent and dependent variables (Attitude towards Use and Intention to Use) are positively correlated. Among the 5 dependent variables, Subjective Norm is found to be the most significant factor contributing to promote online payment attitude and intention through e-commerce websites of Vietnamese consumers.

Endoparasites in pigs raised in smallholder farms in Hung Yen province of Vietnam

As being part of an ongoing project, assessing animal health and food safety risks in smallholder pig value chains in Hung Yen province of Vietnam, the presence of endoparasites was investigated in a repeated study. Three communes, with a total of 545 smallhoder pig farms, from three districts were selected. In each commune, ten farms were randomly chosen. On farm data including farm management and biosecurity measures were recorded by using a checklist and observations. From each farm, one pooled fecal sample was collected from a randomly chosen barn monthly and followed from June to December 2014 for seven months. Fecal samples were analyzed for intestinal parasites by floatation and sedimentation methods. The intensity of most commonly seen parasites was determined by the McMaster counting technique. In 198 collected fecal samples, six types of parasites were detected, namely Eimeria 89 (44.95%), Ascaris suum 43 (21.72%), Strongyloides sp. 41 (20.71%), Trichocephalus suis 19 (9.60%), Fasciolopsis buski 10 (5.05%), and Fasciola 2 (1.01%). Highest intensities were observed for Eimeria (maximum 80900 oocyst/g), followed by Ascaris suum (2400 egg/g), Strongyloides sp. (1900 egg/g), and Trichocephalus suis (1300 egg/g); the others were reported at much lower intensities. Infection levels and intensities of the parasites tended to be higher during the hot months, June to September. No significant difference between communes was found. At least one type of parasites was present in 137 samples (69.19%). Most of farms (96.67%) were positive for at least one type of parasites in at least one sample. There was a significant difference in infection level of endoparasites between biogas and non-biogas farms. The general high parasite burden reported in this study will be addressed in future interventions which will include parasite control apart from other measures

Does exporting spur firm productivity and promote inclusive growth? : evidence from Vietnam

Are exporting firms superior because only superior firms choose to become exporters or do they become superior by virtue of being exporters and having to face greater competition and to specialize in core activities? Findings show that the decision to export induces a gain in capital productivity for the new exporters, but no significant effect is observed for labour productivity and Total Factor Productivity (TFP). This result offers some support for the learning-by-exporting effect that occurs within a sector. Entry of Vietnamese firms into the world market can spur inclusive economic growth of the country

Chemical constituents from the leaves of Styrax argentifolius H.L. Li and their antioxidative activity

Searching for bioactive agents from medicinal plants, the phytochemical investigation on the EtOAc extract of the Vietnamese Styrax argentifolius leaves has resulted in the isolation and structural determination of five compounds, including one nor-neolignan egonoic acid (1), one lignan (+)-pinoresinol (2), one sterol (20R)-3β-hydroxysitgmasta-5,22-dien-7-one (3), and two triterpenoids lupeol (4), and 2α,3α,24-trihydroxy-urs-12-en-28-oic acid (5). The chemical structures of these secondary metabolites were elucidated by NMR and MS spectral data. All isolated compounds were first observed in S. argentifolius species. Sterol 3 and triterpenoid 5 were detected in genus Styrax for the first time. With the IC50 value of 19.10 µg/mL, compound 2 possessed the strong activity in DPPH radical scavenging assay
