AbstractHow and where do relationships arise that can be rendered diagrammatically? Do they emerge through the process of human reasoning or through the act of drawing on surface? Or do they unfold in the dynamic processes at play in observable reality? The following article argues that the latter is the case, making recourse to the philosophy of Charles Sanders Peirce. As a case study, it explores Galileo Galilei’s investigation of free-fall motion and examines both printed texts and manuscripts in order to understand how Galilei arrived at his conclusions. While the published diagrams present his results in graphic traditions that date back to the 14th century, Galilei’s handwritten sketches and notes demonstrate the difficult process of hypothesis formation. In these documents we can observe Galilei grappling with adapting the forms of older diagrammatical notation to his experiments. Through close observation of the phenomena in front of him, Galileo tries to comprehend clearly which parameters of motion can be measured and correlated on the inclined plane.

Pragmatic Justification

Argumentation schemes are forms of argument that capture stereotypical patterns of human reasoning, especially defeasible ones like argument from expert opinion, that have proved troublesome to view deductively or inductively. Much practical work has already been done on argumentation schemes, proving their worth in A1 [19], but more precise investigations are needed to formalize their structures. The problem posed in this paper is what form justification of a given scheme, as having a certain precise structure of inference, should take. It is argued that defeasible argumentation schemes require both a systematic and a pragmatic justification, of a kind that can only be provided by the case study method of collecting key examples of arguments of the types traditionally classified as fallacies, and subjecting them to comparative examination and analysis. By this method, postulated structures for schemes can be formulated as hypotheses to solve three kinds of problems: (1) how to classify such arguments into different types, (2) how to identify their premises and conclusions, and (3) how to formulate the critical questions used to evaluate each type of argument.

Academic Discussion

Bourdieu’s concepts of legitimacy and symbolic capital have provided invaluable insights for the structures of social relations. These concepts have been used by many researchers in many different fields. However, there is a lack of academic discussion using these two concepts to study the connection between legitimacy and the practice of symbolic capital in the field of kebaya. Referring to this fact, this study aims to fill the gap. Therefore, this project is intended to examine how legitimacy is gained by an Indonesian female kebaya designer, Anne Avantie, and how the symbolic capital operates in the field of kebaya. In an attempt to collect the data, a close observation on a kebaya show held by Anne Avantie had been done and some articles about her had been read. Meanwhile, this project applies a qualitative method. The research finding shows that Avantie initially received legitimacy as a kebaya designer from consumers and then followed by many other important parties such as politicians, many organizations and institutions. This success generates the symbolic capital that puts her as a kebaya trandsetter and enables her to change the doxa of kebaya. Keywords: legitimacy, symbolic capital, doxa, field of kebaya

Resistant Medium

The motion of a particle that is projected into a resistant medium and subjected to a uniform gravitational field is considered. The drag force that acts upon the particle within the medium is proportional to the particle’s speed, the density of the medium, and the cross-section area of the projectile. We review the problem of a horizontal motion with a drag force that is linear in speed. The problem is formulated in terms of particle speed, mass, height, time, and expelled gas velocity. The equations of motion are solved analytically, and a case study is discussed. As a result, we obtain the deviation of the projectile as a function of time because of the expelled gases with or without drag force.

The Impact

This chapter presents an analysis of the dynamics of children’s digital games interactions, which take place in their home surroundings, based on empirical case study. Since digital games have become one of the main building blocks in children’s world, there is a need to examine the impact of the widespread use of digital games in children’s everyday life. The study’s framework served as a window for close observation of the ways young children spontaneously play digital games and interact with each other. Theoretical implications for digital games research and the pedagogical implications regarding the design and implementation of interactive learning environments are discussed. In addition, there are methodological challenges of finding new pathways for studying the complex relationships between digital games and real-world learning interactions. The study’s findings and their implications could serve as a small step in perusing these challenges.

The Impact

An incline impact test can be used as a shock test in lieu of a drop test in several test protocols, including ISTA Procedure 1A [1]. Some test protocols, such as ISTA Procedure 1E [2], only allow for an incline impact test and horizontal impact test. In this case study, a graph was developed for a 500-lb impact tester at Christian Brothers University (CBU) Packaging Laboratory. It determines sliding platform location on the incline for a given packaged-product weight to meet the impact velocity recommended by the International Safe Transit Association (ISTA). One station of the platform location higher than the station obtained from the graph is recommended to ensure the meeting of ISTA recommended impact velocity. It is well known that weight is not used in impact velocity of a free fall drop. However, this case study shows that weight contributes to impact velocity of an incline impact test. It contributes to the rolling friction. A heavier weight yields a smaller coefficient of rolling friction ( 𝜇𝑘 ), which results in a higher impact velocity. The coefficient of rolling friction for CBU’s incline impact tester can be computed from 𝜇𝑘 = −9 −5𝑤 + 0.1092, where w is the total weight of the sliding platform and packaged product.

Pictorial Representations

Johannes Gutenberg designed his edition of the Vulgate without illustrations. However, the subsequent evolution of media affected the vernacular appropriation of the Holy Scripture. Vernacular printed Bibles typically featured extensive pictorial representations of the biblical narrative. From an iconographic perspective, this case study examines which types or parts of the images were maintained, transferred but also reconfigured in the woodcuts. In addition, from the perspective of reader-response criticism, it analyzes how the placement of illustrations guides, structures and augments the reading of the Holy Scripture. While the canonical biblical text follows a 14th-century German translation, these illustrations offer new ways of understanding. By looking at the conceptions of Creation, Paradise and Fall of Man in pre-Reformation printed Bibles, this case study examines how religious knowledge changed through these processes of appropriation in the context of a print production which was no longer dominated by clerical but commercial interests. Finally, the findings are compared with Luther’s Bible.

The notion of a new retail geography poses the challenge to produce more critical and rigorous analyses of an important sector of the UK service economy. In this paper we suggest that our understanding of retail processes will be aided by devoting explicit attention to the role of interorganisational power in shaping the commercial environment of the retail sector. Regrettably, many notions of power are undertheorised and static. In particular there is a tendency to treat power as a commodity that may be ‘bought’ rather than as dynamic and relational. We therefore suggest that a modified version of Clegg's model of circuits of power can add a much-needed dynamic element to a new retail geography. The circuits of power framework is applied to a case study from UK food retailing. The approach clarifies the underlying and inherently dynamic processes of power-based inequality that are driving change.
