Ranging patterns of a troop of baboons (Papio anubis) in Kenya.

A troop of olive baboons, Papio anubis, was studied for 11 months in an open-country habitat near Gilgil, Kenya. Detailed mapping of troop movements was undertaken and provided a precise picture of range usage, showing that a small part of the range was used intensively. Gradations of home range use are described quantitatively. Tendencies to spread out and coalesce in different parts of the range are investigated. Shifting ranging patterns are examined together with meteorological factors, seasonal food supplies and water availability.

Objective and subjective evaluation of psychiatric ward redesign.

The authors describe the redesign and evaluation of a 30-bed psychiatric unit. The design approach was user oriented, employing a psychoenvironmental model that postulates an interaction between the physical environment and the psychotherapeutic milieu. Objective and subjective instruments demonstrated that environmental redesign based on this model correlated with behavioral changes in clinically desirable directions. These changes also correlated with reduced psychopathology and might have been facilitated by "social organizers," design solutions that encourage social interaction focused on ward activities.

The concept of boundaries in clinical practice: theoretical and risk-management dimensions.

The authors systematically examine the concept of boundaries and boundary violations in clinical practice, particularly as they relate to recent sexual misconduct litigation. They selectively review the literature on the subject and identify critical areas that require explication in terms of harmful versus nonharmful boundary issues short of sexual misconduct. These areas include role; time; place and space; money; gifts, services, and related matters; clothing; language; self-disclosure and related matters; and physical contact. While broad guidelines are helpful, the specific impact of a particular boundary crossing can only be assessed by careful attention to the clinical context. Heightened awareness of the concepts of boundaries, boundary crossings, and boundary violations will both improve patient care and contribute to effective risk management.

Gender and race differentials in elderly migration.

A number of studies have provided evidence that elderly migration in the United States is strongly selective in terms of the characteristics of the migrants. Such characteristics as age, gender, and race are commonly used in examinations of migrant selectivity, but the differences in spatial behavior of these subpopulations are still poorly understood. This article uses state-to-state migration data, categorized by age, gender, and race, to explore the comparative patterns of origins, destinations, and migration propensities, with a focus on the southeastern states of the country.

Reacting to autistic children: the danger of trying too hard.

Recent work has revealed that autistic children's predominating tendency to avoid social interactions is actually enhanced by the 'friendly' approaches to others. In this study it was recorded on video-tape how eight autistic children reacted to four styles of adult behaviour. The adult reacted to the child's looks at her by (i) smiling, (ii) gaze averting, (iii) gaze averting plus other 'timid' behaviours and (iv) doing nothing except continuing to look back. For this last condition--when the adult did not react--it was found that autistic children showed less avoidance behaviour after eye contact and spent more time within one metre of the adult. The implications for treatment are contrary to much modern practice and to what seems to be adults' 'natural' response. Reactivity by others appears to enhance the child's avoidance, and it is suggested that adults should be circumspect in the degree of sociability with which they respond to autistic children.

Scaling in nests of a social wasp: a property of the social group.

The numbers of brood cells in nests built by founding swarms of the Neotropical social wasp Polybia occidentalis closely correlate with the numbers of wasps in the swarms. We analyzed nests of different sizes to determine how they scale with respect to the allocation of brood cells among combs. Three patterns were evident: compared to smaller nests, larger nests have (1) more combs and (2) larger combs; and (3) among nests containing the same number of combs, the last two combs diverge in relative size as nest size increases. Taken together, these results suggest that members of a swarm somehow "know" the size of the swarm they are in. This information feeds back to individual builders, which quantitatively modulate their responses to stigmergic cues in ways that result in the nest-size-scaled allocation of brood cells among combs. The patterns also suggest that swarms fine-tune the final size of their nests by making corrections as they build.

Continuity of affiliative relationships among infants and juveniles in a free-ranging group of Japanese monkeys (Macaca fuscata).

5 infants were observed during the first 13 mo. after birth in a free-ranging group of Japanese monkeys (Macaca fuscata) to examine whether they maintained relatively frequent affiliative relationships with particular immature individuals. The number of immature affiliative partners rapidly increased from the first 3-mo. period after birth to the second 4-mo. period after birth, and the infants thereafter maintained affiliative relationships with particular individuals, mostly same-aged infants, at least in the second half of their first year. These findings show that infants were likely to interact with a larger number of different animals in the early stage of development, and thereafter selected particular individuals with whom they maintained affiliative relationships. The effects of sex on the selection of these long-term partners are also discussed.

Managing a multicultural radiology staff.

Opportunities for minorities in healthcare increased with the Civil Rights movement in the 1960s. More recently, funds from the U.S. Public Health Service have been targeted toward disadvantaged minorities. The workforce in healthcare, and in business in general, has become increasingly multicultural. Much of the literature in healthcare management lacks practical guidelines for managing a diverse workforce. Communication, both verbal and nonverbal, and culture are closely intertwined. Managers, as they develop multicultural teams, will need to understand how culture influences communication in their organizations. Space, spatial behavior, and cultural attitudes influence people's behavior. This is a particularly important consideration for a radiology staff, which must often work in close quarters. For some cultural groups, the family as an organization has more significance than even personal, work-related or national causes. People's orientation to time, whether for the past, present or future, is usually related to the culture in which they grew up. Again, this may become an important issue for a radiology administrator whose organization must run punctually and time-efficiently. How patients feel about their environment, whether they believe they are in control or believe in an external locus of control, is of particular interest to those who attempt therapeutic changes in a patient's healthcare. Does the patient believe that illness is divine will or that suffering is intrinsic to the human condition? There is increasing research in the United States to show that people do differ biologically according to race. Such differences exist among patients as well as among staff members. It has been popular to assume that differences among races do not exist. Unfortunately such an attitude does not allow for different attributes and responses of individuals. Managing a multicultural staff presents a challenge to administrators who must be skilled in working with culturally diverse people and must help their staff members do the same.

Optic flow input to the hippocampal formation from the accessory optic system.

Recent studies in rodents have implicated the hippocampal formation in "path integration": the ability to use self-motion cues (ideothesis) to guide spatial behavior. Such models of hippocampal function assume that self-motion information arises from the vestibular system. In the present study we used the retrograde tracer cholera toxin subunit B, the anterograde tracer biotinylated dextran amine, and standard extracellular recording techniques to investigate whether the hippocampal formation [which consists of the hippocampus proper and the area parahippocampalis (Hp/APH) in pigeons] receives information from the accessory optic system (AOS). The AOS is a visual pathway dedicated to the analysis of the "optic flow fields" that result from self-motion. Optic flow constitutes a rich source of ideothetic information that could be used for navigation. Both the nucleus of the basal optic root (nBOR) and nucleus lentiformis mesencephali of the AOS were shown to project to the area ventralis of Tsai (AVT), which in turn was shown to project to the Hp/APH. A smaller direct projection from the nBOR pars dorsalis to the hippocampus was also revealed. During extracellular recording experiments, about half of the cells within the AVT responded to optic flow stimuli. Together these results illustrate that the Hp/APH receives information about self-motion from the AOS. We postulate that this optic flow information is used for path integration. A review of the current literature suggests that an analogous neuronal circuit exists in mammals, but it has simply been overlooked.
