“…As organic farming was just an idea during this period, there was no need for further comprehensive investigations. Only in the last decade of the 20 th century, after intensive development of organic sector, these methods were intensively investigated and developed (Clark Also, computerization of seed treatment devices enabled precise control of treatment processes, which was unachievable in the previous decades (Boon, 2015). The most efficient and popular methods were low energy electron treatment patented as e-ventus in Germany by the company Evonta (Jahn et al, 2005;Röder et al, 2009;Evonta, 2019).…”

Low energy electrons (electron treatment), aerated steam (thermal treatment) and a bacterial product Cedomon containing Pseudomonas chlororaphis (bacterial treatment) were selected for the trial as the most popular seed treatment methods in Western and Northern Europe. This trial was aimed to evaluate the effect of treatments on seed sanitation, crop and disease development and yield parameters. Two spring barley (Hordeum vulgare L.) cultivars 'Luokė' and 'Alisa DS' were investigated during 2014-2015 under the conditions of Central Lithuania. Low energy electron treatment was found to exert a negative effect: the mean yield decrease was 20% compared to the control. The yield reduction resulted from the inefficient seed sanitation and reduced field emergence compared to the control. Thermal treatment increased the yield by an average of 35%, viz. in 2014 by 58% and in 2015 by 13%. The yield increase was influenced by very efficient seed sanitation in the first year but not in the second year. Bacterial treatment with Cedomon increased the yield by an average of 3%. This treatment improved neither seed health nor crop stand density in 'Luokė'; however, it had a positive effect on the seeds of 'Alisa DS' in both experimental years. Improved seed health increased grain yield in 'Alisa DS', while poor seed health decreased yield in 'Luokė'. None of the seed treatment methods tested showed consistent and unquestionable results. The yield increase depended mainly on the improved seed health, thus the main strategy to produce stable yield is seed health testing of the lots intended for use in organic agriculture.Please use the following format when citing the article: Liatukas Ž., Supronienė S., Ruzgas V., Leistrumaitė A. 2019.

“…We manipulate objects to make them observable (for instance by slicing and staining objects for microscopy), and we organize the conditions of our observations in order to make them suitable for conclusions about regularities in nature (i.e., we construct experiments). We also build instruments for our observations (Boon 2015 ).…”

Philosophy of Technology After the Empirical Turn

View full text Add to dashboard Cite

The notion of practical arts goes back to antiquity. It covers what we today call technology but also many other types of activities, such as farming, manual crafts, cooking, housekeeping, sport activities, artistic work, and medicine. Interesting discussions on the practical arts can be found in medieval texts on knowledge classifi cation for instance by Hugh of Saint Victor and Robert Kilwardby, and also in Renaissance and Enlightenment literature. In this chapter it is argued that the philosophy of practical arts should be revitalized and that the philosophy of technology should have a major role when this is done. Many of the topics studied in the latter discipline have interesting extensions to practical arts in general. Some examples are the relationship between action knowledge and factual knowledge, the epistemological roles of actions, explanations in practical knowledge, and the role of functional terms and descriptions. The Empirical Turn in the Philosophy of Technology provides an excellent starting-point for widening the philosophy of technology to a general philosophy of the practical arts.

“…Philosophical studies of the use of technology in making and recording empirical observations are relevant here. See Boon (2015). 15 As I see it, computer simulations are experiments on a model of the ultimate object of study.…”

In spite of their practical importance, the connections between technology and mathematics have not received much scholarly attention. This article begins by outlining how the technology-mathematics relationship has developed, from the use of simple aide-mémoires for counting and arithmetic, via the use of mathematics in weaving, building and other trades, and the introduction of calculus to solve technological problems, to the modern use of computers to solve both technological and mathematical problems. Three important philosophical issues emerge from this historical résumé: how mathematical knowledge depends on technology, the definition of the hybrid concept of a (technological) computation, and the (perhaps surprising) usefulness of mathematics in technology. Each of these issues is briefly discussed, and it is shown that in order to analyze them, we need to combine tools and ideas from both the philosophy of technology and the philosophy of mathematics. In conclusion, it is argued that much more of interest can be found in the historically and philosophically unexplored terrains of the technology-mathematics relationship.
