Perfect colourings of isonemal fabrics by thin striping
Perfect colouring of isonemal fabrics by thin striping of warp and weft and
the closely related topic of isonemal prefabrics that fall apart are
reconsidered and their relation further explored. The catalogue of isonemal
prefabrics that fall apart is extended to order 20 for those of even genus.Comment: 25 pages, 20 figure
Satin Non-Woven Fabrics for Designing of Self-Regulating Breathable Building Skins
In this paper, we introduce the concept of 2-way 2-fold genus-1 non-woven
fabrics that can be used to design self-regulating breathable building skins.
The advantage of non-woven structures over woven structures for breathable skin
design is that they can completely be closed to stop air exchange. We have
developed a theoretical framework for such non-woven structures starting from
the mathematical theory of biaxial 2-fold Genus-1 woven fabrics. By
re-purposing a mathematical notation that is used to describe 2-fold 2-way
2-fold genus-1 woven fabrics, we identify and classify non-woven fabrics.
Within this classification, we have identified a special subset that
corresponds to satin woven fabrics and allows for maximum air exchange. Any
other subset of non-woven structures that correspond to other classical 2-way
2-fold genus-1 fabrics, such as plain or twill, will allow for less air
exchange. We also show that there exists another subset of satin non-woven
fabrics that can provide the biggest openings.Comment: 10 page

The Social Structure of Consecration in Cultural Fields: The Influence of Status and Social Distance in Audience–Candidate Evaluative Processes
Building on sociological research that examines the allocation of rewards in peer evaluations, we argue that the recognition of cultural producers’ work varies with their status and social distance from the audience members who evaluate them. We study the influence of these two mechanisms within the context of the Norwegian advertising industry. Specifically, we looked at how cultural producers’ status and social distance from jury members affect their chances of being honored in “The Silver Tag” – one of the main digital advertising award contests in Norway – during the period 2003–2010. While our findings provide support for status-based rewards allocation, the positive effects of status may be more circumscribed than previously thought. When accounting for the existence of previous connections between audience members and cultural producers, we find that cultural producers are more or less likely to receive an accolade depending on their degree of separation from the audience members. By exposing network-based determinants of consecrating decisions, and suggesting that the positive effects of status may be more circumscribed than previously thought, our findings shed important light on the social foundations of evaluation and, more broadly, the mechanisms of reward allocation in cultural fields
Perfect Colourings of Isonemal Fabrics by Thick Striping
Perfect colouring of isonemal fabrics by thick striping of warp and weft and
the closely related topic of isonemal prefabrics that fall apart are
reconsidered and their relation further explored. The catalogue of isonemal
prefabrics of genus V that fall apart is extended to order 20 with designs that
can be used to weave cubes with colour symmetry as well as weaving symmetry.Comment: 50 diagram

Friends, Cliques and Gifts: Social Proximity and Recognition in Peer-Based Tournament Rituals
Two main accounts of the effect of proximity between candidates competing for recognition and members of the evaluating audience in the underlying social structure can be extrapolated from extant literature on peer-based tournament rituals and cultural fields. Following a Bourdieusian tradition, one account – which we label self-reproduction – insists on the catalyzing effect of social proximity in shaping recognition along relational lines. Drawing from recent scholarship on social evaluation, a second account – which we label intellectual distance – suggests that social proximity deters recognition. We probe the influence of different articulations of social proximity (i.e., direct ties, cliquishness and reciprocity) on recognition by studying awarding decisions within the context of the Norwegian advertising industry. Interviews with key informants and econometric results suggest that, while self-reproduction tends to prevail over intellectual distance, these effects co-exist and their relative influence varies across levels of recognition. We gauge the relative saliency of the two accounts by using a mix-method approach. Important implications for research on social evaluation and recognition in peer-based tournament rituals are drawn
The Creation of Woven Tiles from the Union of Delaunay Lofts
In this work, we build upon the previously established foundations of Delaunay Lofts, which are a new class of shapes inspired by biological phenomena known as scutoids.
Delaunay Lofts naturally provides edge collapse and vertex split processes, which make them highly complex in terms of topological structure. Delaunay lofts are obtained by layer-by-layer Voronoi decomposition of points. Therefore, any cross-section of a Delaunay Loft is always a convex polygon. Moreover, the only topology change from one layer to another is the change in the number of sides of cross-section polygons. Through our methodology, we obtain woven tiles as the union of Delaunay Lofts. This extension provides two advantages over the original Delaunay Lofts that can lead to woven tiles: (1) Each cross-section polygon can be non-convex, and (2) we can connect and disconnect polygons. To create woven tiles, we use unions of a linear pattern of points that can produce patterns similar to woven textiles. We have only investigated two widely used woven patterns: plain and twill. Plain woven tiles provide an approach to construct generalized Abeille’s flat vaults, which was introduced by French engineer and architect Joseph Abeille. Twill patterns provide even further generalizations of Abeille’s vaults, thus demonstrating the existence of a general class of woven tiles. By taking the union of several individual Delaunay Lofts, woven tiles appear in the resulting structure. Using this method, we are able to create non-convex polygons, as well as connecting and disconnecting the polygons in any manner we desire. Additionally, we can design the resulting shapes on each layer since we have control of the Voronoi Site locations. In developing this approach, we created a procedural framework that allows for the manipulation of rules and guidelines for the creation of the Delaunay Loft. As a result, we are able to generate a wide variety of Woven Structures based on Delaunay Lofts from tweaking various parameters. Using this method, we 3D printed some Woven Structures in order to help analyze symmetrical, structural, and tiling properties
Moral reasons : particularism, patterns and practice
This is the study of the extent of the patternability of the reason-giving behaviour of
morally relevant features in different ethical contexts. Whether or not the way in which a
morally relevant feature contributes to the moral evaluation of different cases is
generalis able is examined in this research. I argue in favour of a core and constitutive
modest-generalistic theme, according to which there are general patterns of word use, to
which the reason-giving behaviour of moral vocabulary in different contexts is
answerable. To this end, I reject the constitutive particularistic claim which holds that the
way in which a morally relevant feature behaves in different cases is fully context-dependent.
An account drawn from Wittgenstein with regard to the nature of concepts
which emphasises the key role of the concept 'practice' is presented to give an account of
how the reason-giving behaviour of a morally relevant feature in different contexts is
answerable to general patterns of word use. Ross's ethics is introduced as an example of
the modest-generalistic position. To substantiate this modest-generalistic position, an
apparent dilemma is presented for particularists, e.g. Dancy. In order to resolve the
second horn of the dilemma, which is an example of a general problem with which any
generalistic account is confronted, the account drawn from Wittgenstein with regard to
the nature of concepts is again used. Finally, a distinction between the first order and the
second order account of the concept 'practice' is presented to give a more plausible
account of the concept 'practice' which has an indispensable role in the Wittgensteinian
account

The Social Corporation: Firms, Networks, and Politics
Scholars have long looked at business as a source of political power, but have come to differing conclusions about how corporations behave in pursuit of interests. Building on organizational theory and conditional choice literature, I hypothesize that corporations react to the actions of those around them, leading to cooperation and coordination. While others point to the importance of social ties created through corporate board memberships, I locate an additional social tie that takes place through trade association memberships. In addition, I demonstrate that rather than fragmenting in recent years, business has in fact become more cohesive in their giving patterns.
Using data from the 1990-2012 United States House of Representatives elections and lobbying expenditure, along with a survey of corporate executives, and employing community detection and network autocorrelation, I demonstrate that corporations have become more closely aligned in their political giving, and further, that common trade association membership is a significant predictor of corporate political activity
