This paper extends the research conducted on male bonding in locker rooms to another well-known but under-researched site, the campus bar. Through a life history of a former athlete, we learn about the connection between what is said in the locker room and behavior outside. We also gain insight into the role campus bars play in facilitating aggression and sexual misconduct by male athletes.

The British Library's “An Oral History of British Science” (OHBS) was created in 2009 to address the dearth of oral history archives in the United Kingdom dedicated to capturing the personal experiences of British scientists. This article examines the implications of using an oral history archive from the perspective of a historian of science to write about scientists’ identities during their doctoral research. The advantages of using life history interviews to explore scientists’ stories are situated within the longer historiographical trajectories of oral history and the history of science. In addition, this article reflects on the process of using a recent oral history archive that has not only allowed for an almost unprecedented access into the personal and working lives of recent scientists but also afforded a greater insight into the creation and aims of the OHBS itself.

This chapter poses the question of the evolution of intellectual faculties. But a satisfactory explanation demands insight into the evolutionary origins of some of our most striking attributes—our intelligence, language, cooperation, teaching, and morality—yet most of these features are not just distinctive, they are unique to our species. That makes it harder to glean clues to the distant history of our minds through comparison with other species. At the heart of this challenge lies the undeniable fact that we humans are an amazingly successful species. Our range is unprecedented; we have colonized virtually every terrestrial habitat on Earth; exhibit behavioral diversity that is unparalleled in the animal kingdom; and resolved countless ecological, social, and technological challenges. When one considers that the life history, social life, sexual behavior, and foraging patterns of humans have also diverged sharply from those of other apes, there are grounds for claiming that human evolution exhibits unusual and striking features that go beyond our self-obsession and demand explanation.

Detailed data on the response of plants to different climatic conditions could gain insight into the early impacts of climate change upon functioning ecosystems especially alpine ones, the most specialized. <em>Petasites kablikianus</em> (Asteraceae) is a species with montane and disjunctive distribution range, and it is one of the best objects to such investigations. In Polish high mountains, it is represented the best on the northern slopes of the Babia Góra massif (the Babiogórski National Park) and it occurs in two, independent zones: subalpine (landslides, rock rubbles) and lower montane zone (gravels on stream banks). The climatic differences between these two zones result in a morphological differentiation of specimens but mainly in differences in the dynamics of the life history of both populations. Detailed phenological observations and biometrical measurements were made on five plots on both gynodynamic and androdynamic shoots in their natural environment and after transplantation. The most important result is a fact that the subalpine population is completely phenologically isolated. Moreover the differences in the dates of beginning vegetation and in the duration and dynamics of particular stages of development and in morphological structure of individuals between the upper and lower populations were also stated. The results show that the adaptability of the species present a great potential to respond to the possible effects of global warming by modifying the life history and extending of distribution range for low-lying areas.

The literature on disease phobia is discussed and a controlled study of this variety of hypochondriasis is presented. There were 30 disease phobic and 30 control subjects, in-patients of a general hospital psychiatric unit in Sydney. Controls were defined as lacking the symptoms ‘disease phobia’, ‘disease conviction’, ‘somatic preoccupation’ and ‘psychogenic pain’. Matching was one-for-one and concerned sex, age and occupational prestige. In brief, the disease phobics were more anxious and self-pitying (current mental state). Before the illness they were more prone to inhibition of anger, bodily concern and low selfesteem (personality variables). As children they were more often weak, sickly and overprotected. Fifteen were youngest siblings versus only six of the controls. They gave a history of much family illness, substantiated by the findings of an excess of deaths among the mothers of disease phobics (life history characteristics). They reported an electrical current as a sensation at relatively low voltages and had low tolerance of pain (experimental measures). A logical insight into the origins of disease phobia is provided by inter-relating the data from these four aspects of the investigations (Fig. 1). This matrix is interpreted in terms of the augmentation-reduction theory of Petrie.
