Element Modelling

Object manufacture in insects is typically inherited, and believed to be highly stereotyped. Optimization, the ability to select the functionally best material and modify it appropriately for a specific function, implies flexibility and is usually thought to be incompatible with inherited behaviour. Here, we show that tree-crickets optimize acoustic baffles, objects that are used to increase the effective loudness of mate-attraction calls. We quantified the acoustic efficiency of all baffles within the naturally feasible design space using finite-element modelling and found that design affects efficiency significantly. We tested the baffle-making behaviour of tree crickets in a series of experimental contexts. We found that given the opportunity, tree crickets optimised baffle acoustics; they selected the best sized object and modified it appropriately to make a near optimal baffle. Surprisingly, optimization could be achieved in a single attempt, and is likely to be achieved through an inherited yet highly accurate behavioural heuristic.

Males And Females

The breeding biology of tree frog, Polypedates teraiensis was studied during the breeding season at Mizoram University Campus. It was found that sound production by male during the breeding season was primarily a reproductive function and advertisement calls attract females to the breeding areas and announce other males that a given territory is occupied. The aim of this study was to provide the detailed information on the breeding behaviour and the advertisement calls of Polypedates teraiensis. The morphometric measurements of the amplecting pairs (males and females) for sexual dimorphism along with clutch sizes were also studied.

This essay seeks to dispel entrenched critical opinion regarding dance across Nietzsche's writings as representative of Dionysian intoxication alone. Taking as its prompt the riposte of Alain Badiou, ‘Nietzsche is miles away from any doctrine of dance as a primitive ecstasy’ and ‘dance is in no way the liberated bodily impulse, the wild energy of the body’, the essay uncovers the ties between dance and Apollo in the Nietzschean theory of art while qualifying dance's relation to Dionysus. Primarily through an analysis of The Dionysiac World View and The Birth of Tragedy, the essay seeks to illuminate enigmatic statements about dance in Nietzsche (‘in dance the greatest strength is only potential, although it is betrayed by the suppleness of movement’ and ‘dance is the preservation of orderly measure’). It does this through an elucidation of the specific function of dance in Nietzsche's interpretation of classical Greece; via an assessment of the difficulties associated with the Nietzschean understanding of the bacchanal; and lastly through an analysis of Nietzsche's characterization of dance as a symbol. The essay culminates in a discussion of dance's ties to Nietzschean life affirmation; here the themes of physico-phenomenal existence, joy and illusion in Nietzsche are surveyed.

This article concerns with the characteristics of the language of three British female Youtubers. It is aimed in particular to find out women's linguistic features in their language based on Lakoff's theory (1975) and the functions of each features according to Holme's theory (2013). The result of the study reveals  seven women's linguistic features  in the youtubers' language. They are (1) lexical hedges or fillers, (2) tag questions, (3) „empty‟ adjectives, (4) precise color terms, (5) intensifiers, (6) „superpolite‟ forms, and (7) emphatic stress. Among these features, the intensifiers. appears as the dominant one. The study also shows that each feature has specific function.

Household Processing

This article assembles examples of an unusual vessel found in domestic contexts of the Early Bronze Age around the Aegean and in the Eastern Mediterranean. Identified as a “barrel vessel” by the excavators of Troy, Lesbos (Thermi), Lemnos (Poliochni), and various sites in the Chalkidike, the shape finds its best parallels in containers identified as churns in the Chalcolithic Levant, and related vessels from the Eneolithic Balkans. Levantine parallels also exist in miniature form, as in the Aegean at Troy, Thermi, and Poliochni, and appear as part of votive figures in the Near East. My interpretation of their use and development will consider how they compare to similar shapes in the archaeological record, especially in Aegean prehistory, and what possible transregional relationships they may express along with their specific function as household processing vessels for dairy products during the third millennium BC.

Unique Application

Using complete enumeration (e.g., generating all possible subsets of item combinations) to evaluate clustering problems has the benefit of locating globally optimal solutions automatically without the concern of sampling variability. The proposed method is meant to combine clustering variables in such a way as to create groups that are maximally different on a theoretically sound derivation variable(s). After the population of all unique sets is permuted, optimization on some predefined, user-specific function can occur. We apply this technique to optimizing the diagnosis of Alcohol Use Disorder. This is a unique application, from a clustering point of view, in that the decision rule for clustering observations into the diagnosis group relies on both the set of items being considered and a predefined threshold on the number of items required to be endorsed for the diagnosis to occur. In optimizing diagnostic rules, criteria set sizes can be reduced without a loss of significant information when compared to current and proposed, alternative, diagnostic schemes.
