Wood Boring

Monochamus notatus (Drury) and M. scutellatus (Say) are both common wood-boring beetles in the coniferous forests of eastern Canada. The two species are usually separated on the basis of colour. The first is dark brown with lighter brown elytra, and is covered with white and brown pubescence, while the second , is typicaliy shining black. The scutellum of each bears a dense white pubescence which, in the case of M. notatus, is divided by a bare median line. Such a line also occurs in M. scutellatus but is usually incomplete. The writer has found that the presence or absence of a fringe of white hair around the compound eye constitutes the most consistent anatomical difference between the two species, it being present only in M. notatus. The elytra of the females of both species are generally marked with elongate spots. Body length is also used to separate the two species, but no clear-cut difference in length ranges occurs; instead, there is considerable overlap.

Specific cases are cited which show the existence of a clear-cut frontal zone at the 500-mb level. The relationship of this frontal zone to the location of the jet stream and to the formation of surface disturbances can be used as a valuable tool for forecasting. The value of the data received from weather reconnaissance flights is emphasized and recommendations for improving these flights are given.

The introduction to the special issue taps into discussions about the inseparability of science and fiction. Commencing from the idea that scientific statements are distinguished from fiction only a posteriori, not a priori, the piece asks, how fiction could be used as a theoretical resource in social scientific thinking. Could it inform, enrich, extend, intensify, and challenge the sociological imagination? Besides rejecting any clear-cut separation of social science and fictional and artistic forms, the text seeks to unsettle our certainty as to what counts as “fact” and what as “fiction” in the first place. It also suggests that examining the relationship of sociology and fictional and artistic forms helps us unsettle the institutionalized disciplinary ways of ordering knowledge and thought and that there may be a poetics or fiction to be uncovered in sociological scholarship, as sociology is also a form of storytelling.

The Relationship

This article centers on the relationship of rules (nīti) to the monastic form of life of contemporary Buddhist nuns in Sri Lanka. A genealogy of scholarship focusing on the rules of Buddhist monks and nuns led scholars to affirm a clear-cut distinction between nuns who have the higher ordination (bhikkhunῑs) and those who do not have it. However, that distinction is not self-evident, because bhikkhunῑs and other nuns lead lives that do not foreground a juridical notion of rules. The lives of nuns focus on disciplinary practices of self-restraint within a tradition of debate about their recent higher ordinations. Whether or not they are bhikkhunῑs, nuns today refer to rules in ways that are different from that which dominant Vinaya scholarship assumes. This article proposes that it is misleading to differentiate Buddhist nuns based on an enumeration of their rules and argues that nuns’ attitudes to rules say more about attempts to authorize claims to power in current debates about their ordination than about their disciplinary practice as a communal form of life.

Structure And Functions

Three distinct forms of eye exist in the Arthropoda j the Compound eye, the Simple- Ocellus, and the less known Compound Ocellus common in larval insects, first described by Dr. Landois. The relationship of the Compound eye to the Simple Ocellus is shown to be very distant, although I believe that these two types have been evolved from a common but very rudimentary primitive type. On the other hand, that between the Compound eye and the Compound Ocellus of a larval insect, is very close, the Compound eye being merely an aggregation of a great number of these ocelli, variously modified in the more highly differentiated Insects and Crustaceans. A fourth form of eye exists, in which the Ocelli are less closely united ; this forms a connecting link between the compound eye and the’ compound ocellus. It is found in the Isopods, and may be conveniently termed the Aggregate eye.

Century Thought

We are used to the view that historically “what counted as fully human always depended … on a sharp contrast with ‘the animal’.” As a consequence, “[w]omen and slaves, in being denied full humanity, were therefore necessarily partaking in animal nature.” Questioning this view, this essay traces how some early modern thinkers defined the relationship of human beings to animals generally, and, more particularly, how they saw the relationship of women, slaves, and animals in the human household. The picture presented, while being far from complete, aims to show that Fifteenth- and Sixteenth-Century thinkers had nuanced arguments to offer when they discussed the relationship of human animals to nonhuman animals, and the relationship of nature and culture, neither of which were presented as clear cut opposites. At the same time, the equation of women with animals and slaves was not something that was commonly found in Sixteenth Century philosophical treatises, which might lead us to rethink our own ideas about equating one disenfranchised group with the other.

Urbanization is a process which is gradually reshaping the population of Pakistan from a nation of farmers and villages to a nation of urban dwellers. Yet this process, so critical to the quality of life in Pakistan's future, is not well understood. The literature of demography and development is liberally sprink¬led with reports and articles dealing with both general theories of urbanization and case studies, but the processes and underlying factors affecting urbaniza¬tion in Pakistan have as yet received little attention.1 Research designed to identify the underlying factors and interpret the urbanization process in Pakistan is currently underway, and it is the purpose of this paper to provide some background information on urbanization in Pakistan as well as to describe the directions of future research. Specifically, this paper examines differential growth among Pakistan's twelve largest cities and the relationship of urban growth to origins and flows of domestic urban migration.

Five new Cortinarius species with medium to large basidiomata are described based on morphological and molecular data. Three of them, Cortinarius aavae , Cortinarius brunneocalcarius , and Cortinarius grosmorneënsis , belong to subgenus Telamonia and one, Cortinarius subfloccopus , to clade /Fulvescentes. The relationship of the fifth species, Cortinarius brunneotinctus , was not solved but it resembles species of clade /Anomali. Cortinarius brunneocalcarius and C. aavae do not have close relatives within the subgenus Telamonia; whereas, C. grosmorneënsis belongs to section Brunnei. Cortinarius grosmorneënsis is only known from eastern Canada, but the other four species have a wide distribution: C. brunneocalcarius and C. subfloccopus occur in North America and Europe, and C. brunneotinctus and C. aavae in western and eastern North America. The descriptions of the novel species are presented and comparison to similar species provided.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.
