Form and Function of Tridacna Shell Plaques from the Western Solomon Islands

Openwork plaques made from tridacna clam shell constitute a significant art form from the Western Solomon Islands. Known facts are relatively few: the plaques were associated with burials and were sometimes used or referred to as a special form of “Custom Money.” Visual analysis of forty-two plaques or plaque fragments indicates that there are three groups separable on the basis of figure style, motifs, composition, and technical considerations such as the relative thickness of the plaques, surface finish, and the like. This article integrates known facts regarding function or use of the plaques with information about other clam shell artifacts from the same islands and with a detailed analysis of the plaques themselves so as to reconstruct something of the traditional cultural context and significance of these artifacts.

And Function

The as-built material behavior of additive manufactured (AM) Titanium (Ti) 6Al-4V is investigated in this study. A solution heat treated, aged, stress relieved, and hot isostatic pressed Laser Powder Bed Fusion (LPBF) AM process was used to manufacture the specimens of interest. The motivation behind this work is based on the ever-growing desire of aerospace system designers to use AM to fabricate components with novel geometries. Specifically, there is keen interest in AM components with complex internal cooling configurations such as turbine blades, nozzle vanes, and heat exchangers that can improve small scale propulsion performance. Though it is feasible to three-dimensionally print parts that meet the Fit portion of a part characteristic description and identification, the Form and Function portions have proven to be more difficult to conquer. This study addresses both the Form and Function characteristics of the LPBF AM process via the investigation of geometry variation and surface roughness effects pertaining to mechanical properties and fatigue behavior of Ti 6Al-4V. Results show that geometry variation may be the cause of increased vibration fatigue life uncertainty. Also, both fatigue and tensile properties show profound discrepancies associated with surface finish. As-built surface finish specimens have lower fatigue and ductility performance, but the results are more consistent than polished data.

Abstract The form and function of female aggression have been for many years an important social issue that demands investigation. Many studies of female aggression have focused on the perpetration and victimization of girls and young women from western countries. As a result, existing theoretical models and empirical foundations of girls' aggression are based on these defining constructs. The purpose of this article is twofold. The present study of adolescent females in the Cook Islands seeks to understand the role that perpetrators play in the type and the target of aggressive behaviour. It also examines the qualitative findings of girls' aggressive behaviour by boys, girls and their teachers and its gendered relationship inside the Cook Islands environment. The outcomes inspect the cultural context of girls in the Cook Islands that make their understanding and experiences of physical aggression and relational aggression unique and highlight the difficulties of young women positioned themselves between Cook Islands traditional values and asserting their contemporary Cook Islands' identity. The discussion highlights that aggression by girls in the Cook Islands is derived from a particular past and present that can in turn shape understandings of addressing aggression in the future.

The Brain

Horror entertainment is paradoxically popular. It is one of the most consistently popular genres across media, yet it is designed to make audiences feel bad. An evolutionary perspective, one that builds on recent developments in cognitive and evolutionary psychology, can help explain the genre’s popularity as well as its form and function. This chapter argues that horror fiction is crucially dependent on evolved properties of the human central nervous system and that a nuanced and scientifically valid understanding of horror requires that we take human evolutionary history seriously. Horror targets ancient defense mechanisms in the brain. At the same time, horror changes in response to sociocultural context. Hence, the chapter argues for a biocultural critical approach to horror, one that is sensitive to cultural context as well as evolved psychological underpinnings. The chapter explains the rationale of the book and outlines its structure.

The Relationship

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).
