Studies initiated in British Columbia in 1943 showed that Madremyia saundersii (Will.), a native parasite with a wide range of lepidopterous hosts in North America, was a parasite of the spruce bud worm, Choristoneura fumiferana (Clem.). The parasite has been obtained each year since then in moderate numbers and released in infested areas of Eastern Canada. M. saundersii deposits macrotype eggs on the integument of host larvae. The first stage larvae penetrate the integument of the host. The larvae attach themselves to tracheal trunks, where they remain throughout the first and second stages, but during the third feeding stage they wander freely within the body, devouring all the contents. The period from egg deposition to adult emergence was 17 to 23 days under laboratory conditions. The life history and habits of the insect are outlined, and are supplemented by general field observations. The immature stages of the parasite are illustrated and described.

Abstract Although parental care is known to occur in a wide range of teleost fishes, postnatal provisioning of nutrition has been documented rarely. Here, we describe a novel example of bi-parental care in a teleost, i.e. mucus-provisioning behaviour in the scale-eating cichlid Perissodus microlepis endemic to Lake Tanganyika. Field observations revealed that young guarded by their parents frequently glanced towards the body surface of both parents. Furthermore, analyses of stomach contents of the young found the presence of ingested mucus, confirming that the young feed on the mucus secretions of their parents. The frequency of glancing behaviour increased with size of the young up to ~13 mm in standard length, but then declined with further growth. Additionally, the frequency of glancing of young towards their parents was higher when the frequency of foraging on plankton was lower. Underwater cage experiments revealed a higher rate of growth in the young kept in direct contact with their parents than in those not allowed direct contact. We conclude that glancing behaviour in young P. microlepis is a form of direct parental nourishment that confers growth benefits to the young when food abundance is low.

Phryxe pecosensis (Tns.) is a native parasite attacking several species of lepidopterous larvae. It has been reared consistently from collections of the spruce budworm made in British Columbia. The time required from egg deposition to the beginning of the formation of the puparium was 7 to 11 days, the female taking the longer period. The puparium was usually completed within a 24-hr. period and the adult emerged 9 to 11 days later. The life history and habits of the insect are described and the salient characters of the immature stages and the internal reproductive systems of the adults are illustrated and described.

The growth of efficiency and skill of athletes is largely determined by training loads that cause functional changes in the body. Therefore, training loads are one of the main parameters of managing the process of formation of sportsmanship. It is established that each type of decathlon separately requires a wide range of tools and methods for its improvement, which complicates the management of the training process. According to our data, qualified all-rounders use in their training from 300 to 400 different exercises. It is proved that the peculiarity of the competitive activity of decathlon athletes is the need to tune in to each type every time, to switch from one type to another, as well as to break the "mood" of the pause between individual types. In addition, the species themselves differ from each other. One type requires the athlete to show speed and strength qualities, another type requires the athlete to show endurance, the third - a tendency to work of a complex technical nature. As a result, each athlete develops leading, lagging, and "neutral" types. At the current level of development of sports, the results in each type of all-around are so high that it is difficult to assume a sharp jump in the results of a particular athlete of the same class. Therefore, success in competitions depends on how well the athlete will be able to realize their potential and pass, each type of all- around at the level of their personal records.


Writing from a wide range of historical perspectives, contributors to the anthology shed new light on historical, theoretical and empirical issues pertaining to the documentary film, in order to better comprehend the significant transformations of the form in colonial, late colonial and immediate post-colonial and postcolonial times in South and South-East Asia. In doing so, this anthology addresses an important gap in the global understanding of documentary discourses, practices, uses and styles. Based upon in-depth essays written by international authorities in the field and cutting-edge doctoral projects, this anthology is the first to encompass different periods, national contexts, subject matter and style in order to address important and also relatively little-known issues in colonial documentary film in the South and South-East Asian regions. This anthology is divided into three main thematic sections, each of which crosses national or geographical boundaries. The first section addresses issues of colonialism, late colonialism and independence. The second section looks at the use of the documentary film by missionaries and Christian evangelists, whilst the third explores the relation between documentary film, nationalism and representation.

This article explores how the Nahua of late Postclassic Mesoamerica (1200–1521 CE) created living and material embodiments of their wind god constructed on the basis of sensory experiences that shaped their conception of this divinized meteorological phenomenon. In this process, they employed chromatic and design devices, based on a wide range of natural elements, to add several layers of meaning to the human, painted, and sculpted supports dressed in the god’s insignia. Through a comparative examination of pre-Columbian visual production—especially codices and sculptures—historical sources mainly written in Nahuatl during the viceregal period, and ethnographic data on indigenous communities in modern Mexico, my analysis targets the body paint and shell jewelry of the anthropomorphic “images” of the wind god, along with the Feathered Serpent and the monkey-inspired embodiments of the deity. This study identifies the centrality of other human senses beyond sight in the conception of the wind god and the making of its earthly manifestations. Constructing these deity “images” was tantamount to creating the wind because they were intended to be visual replicas of the wind’s natural behavior. At the same time, they referred to the identity and agency of the wind god in myths and rituals.

This article aims to shed light on a particular area in the field of Islamic International law (siyar) treaty in Islamic jurisprudence. It addresses a comparative view of classical jurists of treaties both theoretically and historically and highlights their continued relevance to the contemporary world. Since the concept of treaty a lacuna in scholarship as well as the familiar of international legal theorists to study and integrate the Islamic treaty system into the body of modern international law in order to have a mutual understanding and respect and honor for treaties among nations. I would like to present a series of three parts the first one addresses the concept of treaty in Islamic jurisprudence the second addresses the process of drafting treaties and their conclusion and the third addresses selected treaties, including the treaty of H{udaybiya that took place between Muslims and non-Muslims..

The chapter presents a synthetic account of the young Herder’s metaphysics and epistemology, based on several short pieces from the 1760s, with the intention of bringing into relief their strikingly systematic and coherent nature. The objective is to give the reader a greater sense of the philosophical depth of Herder’s anthropology. The first section examines God’s relationship to the world he creates. The second turns to the analogous relationship, based on interaction, between the soul and the body it builds for itself. And in the third, we bring this all together in order to understand how the embodied soul, through engagement with the world, obtains knowledge, and acquires its identity as a historical-cultural being.

The Introduction sheds light on the reception of classical poetry by focusing on the materiality of the poets’ bodies and their tombs. It outlines four sets of issues, or commonplaces, that govern the organization of the entire volume. The first concerns the opposition between literature and material culture, the life of the mind vs the apprehensions of the body—which fails to acknowledge that poetry emerges from and is attended to by the mortal body. The second concerns the religious significance of the tomb and its location in a mythical landscape which is shaped, in part, by poetry. The third investigates the literary graveyard as a place where poets’ bodies and poetic corpora are collected. Finally, the alleged ‘tomb of Virgil’ provides a specific site where the major claims made in this volume can be most easily be tested.

The Armani high-fashion example illustrates the importance of adaptive rational methods in his founding and developing of an iconic high-fashion firm. Armani adapted stylistically to fashion’s new times in the 1970–80s by creating a new style catering for the career woman. His stylistic adaptation is compared with that of another famous Italian fashion designer, Versace, who instead modernized haute couture fashion and created a succession of glamourous styles. Both leaders exploited the same opportunity but in different ways. The third section compares these leaders’ legacies in the 1990s–2000s and assesses from a long-term perspective how capably they had used adaptive rational methods. The final section shifts the focus from fashion to the cosmetics industry and from Italy to the UK. Anita Roddick used adaptive rational methods to establish The Body Shop corporation in the 1970s–80s. However, she then abandoned rational methods with dire results for her corporation in the 1990s.
