Argumentation Course by Electronic Mail
1997
Abstract This article examines the question of whether electronic‐mail (e‐mail) discussions provide university students with an appropriate and profitable environment for practising argumentation and critical thinking skills. An experiment in which 31 undergraduate students and two tutors engaged in argumentative e‐mail discussions is described. The discussions were related to two set books on the sociology of education. The participants’ perceptions of the discussions and of e‐mail as a study method were evaluated by means of a student questionnaire and tutor interviews. Most of the students found that the discussions included a lot of constructive critique, mutual encouragement and constr…
Downstream Services for Rice Crop Monitoring in Europe: From Regional to Local Scale
2017
The ERMES agromonitoring system for rice cultivations integrates EO data at different resolutions, crop models, and user-provided in situ data in a unified system, which drives two operational downstream services for rice monitoring. The first is aimed at providing information concerning the behavior of the current season at regional/rice district scale, while the second is dedicated to provide farmers with field-scale data useful to support more efficient and environmentally friendly crop practices. In this contribution, we describe the main characteristics of the system, in terms of overall architecture, technological solutions adopted, characteristics of the developed products, and funct…
Mitigating the Climate Change Impacts of Aviation through Behavioural Change
2020
Aviation plays a crucial role for economic development and social welfare, but at the same time it also significantly contributes to climate change. Therefore, if the industry wants to follow the same growth path as it has in the past, it will need to mitigate its environmental impacts more seriously or it may otherwise face regulatory restrictions. The current literature has discussed five mitigation strategies. These are technological changes, market-based changes, operational changes, regulatory changes and behavioural changes. While several authors have regarded behavioural changes as the measure with the greatest mitigation potential, it is also the measure that has received far less a…
The Effect of CMC in Business Emails in Lingua Franca: Discourse Features and Misunderstandings
2018
The paper argues that everyday exchange of business emails produces a development in the work-group relationship, which, in turn, makes new communication styles possible and acceptable by the users' habit to computer-mediated forms, even in unbalanced professional exchanges. The focus is on the (spoken) discourse features of email messages in a self-compiled corpus of selected computer-mediated business emails, produced by five participants over three months (October 2015 – February 2016). The exchange, involving the use of English by non-native speaker interactants (in particular, Business English as a Lingua Franca (BELF)), as well as language adjustments in a computer-mediated exchange, …
Domain-Specific Characteristics of Data Quality
2017
The research discusses the issue how to describe data quality and what should be taken into account when developing an universal data quality management solution. The proposed approach is to create quality specifications for each kind of data objects and to make them executable. The specification can be executed step-by-step according to business process descriptions, ensuring the gradual accumulation of data in the database and data quality checking according to the specific use case. The described approach can be applied to check the completeness, accuracy, timeliness and consistency of accumulated data.
Fluorescence, Browning Index, and Color in Infant Formulas during Storage
2005
Free and total fluorescent compounds, browning index, and color formation were measured in milk-based powdered infant formulas (IF) during 2 years of storage at 20 and 37 degrees C. The excitation spectra from 415 nm emission show three peaks (ex lambda1 = 270 nm, lambda2 = 325/315 nm, lambda3 = 350 nm) and from 347 nm excitation two emission peaks (415 and 520 nm), and no wavelength shifts were observed. Temperature and time of storage exert in general no significant effect on the development of fluorescence emission intensity and browning index. However, an important increase in pentodilysine was recorded-probably because of the iron and ascorbic acid contents of the samples-as well as in…
1-METHYLCYCLOPROPENE DELAYS RIPENING AND IMPROVES POSTHARVEST QUALITY OF WHITE FLESH LOQUAT
2015
The ethylene inhibitor 1-methylcyclopropene (1-MCP) delayed ripening and improved postharvest fruit quality of loquat (Eriobotrya japonica Lindl.). 1-MCP was used on the white flesh sub-acid loquat cultivars ‘Claudia’ and ‘BRT20’ to evaluate the possible effect on fruit ripening and to prevent negative effects of cold storage, like internal browning and flesh leatheriness. 1-MCP was applied at 2°C for 20 h and concentrations of 1 and 5 μl L-1. After 1-MCP treatment fruit were held at 2°C for 7, 14, and 21 days and then moved to 18°C for 5 days. Fruit flesh firmness, titratable acidity (TA), total soluble content (TSS), weight loss, internal browning and flesh leatheriness were evaluated at …
Simultaneous analysis of lysine, Nɛ-carboxymethyllysine and lysinoalanine from proteins
2007
Protein quality was assayed by simultaneous measurement of lysine (Lys), carboxymethyllysine (CML) and lysinoalanine (LAL). GC-FID analysis of N-tert-butyl dimethylsilyl (tBDMSi) derivatives of these amino acids was undertaken. tBDMSi derivates were separated on a CP-SIL 5CB commercially fused silica capillary column (25 m × 0.25 mm i.d., 0.25 μm film thickness) employing a thermal gradient programmed from 200 to 300 °C. The identity of tBDMSi derivatives of Lys, CML and LAL was established by GC–MS while FID detection was employed for quantification. Analytical parameters such as linearity (lysine 350–4200 μM, LAL 3–81 μM, CML 16–172 μM), precision (1–13% variation coefficients), accuracy …
High-performance liquid chromatographic determination of furfural compounds in infant formulas during full shelf-life
2005
Abstract In order to evaluate the extent of the Maillard reaction in adapted and follow-up infant formulas (IF), a study was made of the evolution of furfural compound (2-furaldehyde, 5-hydroxymethyl-2-furfuraldehyde, 2-furylmethylketone and 5-methyl-2-furaldehyde) in these products, along with their relation to available lysine during the shelf-life period (two years at 20 and 37 °C). Total and free furfural contents were measured by RP-HPLC and UV detection, heating or not the sample in boiling water to free the furfurals bound to proteins and the furfurals formed from precursors. Only 2-furylmethylketone and 5-hydroxymethyl-2-furfuraldehyde were detected. Adapted and follow-up IF showed …
Nonenzymatic glycation reaction of folate with reducing sugars: A case study on [6S]-5-methyltetrahydrofolate and fructose
2006
In the Maillard reaction, free amino groups react with reducing sugars to form nonenzymatic glycation products. It has recently been shown that in the presence of reducing sugars (i.e. fructose) folic acid is subjected to a non-enzymatic glycation reaction, which may represent an important pathway of folate degradation besides the established oxidative degradation pathways. In the current study, the thermal stability of [6S]-5-methyltetrahydrofolic acid ([6S]-5-CH3H4PteGlu, 0.4µM), the predominant naturally occuring folate derivate, was investigated on a qualitative and kinetic basis in the presence of different fructose concentrations (0-3M) in milliQ water (8.11ppm O2). Samples were isoth…
