Perceiving affect from arm movement.

We examined the visual perception of affect from point-light displays of arm movements. Two actors were instructed to perform drinking and knocking movements with ten different affects while the three-dimensional positions of their arms were recorded. Point-light animations of these natural movements and phase-scrambled, upside-down versions of the same knocking movements were shown to participants who were asked to categorize the affect of the display. In both cases the resulting confusion matrices were analyzed using multidimensional scaling. For the natural movements the resulting two-dimensional psychological space was similar to a circumplex with the first dimension appearing as activation and the second dimension as pleasantness. For the scrambled displays the first dimension was similar in structure to that obtained for the natural movements but the second dimension was not. With both natural and scrambled movements Dimension 1 of the psychological space was highly correlated to the kinematics of the movement. These results suggest that the corresponding activation of perceived affect is a formless cue that relates directly to the movement kinematics while the pleasantness of the movement appears to be carried in the phase relations between the different limb segments.

Trends in provision of distal arterial reconstruction in Scotland 1989-1999.

OBJECTIVES: to establish if access to distal arterial reconstructive surgery is equally distributed within the health boards of Scotland and to establish if any variations in practice are reflected in lower limb amputation. METHODS: a retrospective, descriptive study using hospital discharge data (Scottish Morbidity Record-1) from 1989 to 1999. RESULTS: the rate of distal arterial reconstruction in Scotland increased from 0.9 per 100 000 population in 1989, peaked at 2.6 per 100 000 in 1994 and has since declined steadily to 1.6 per 100 000 in 1999. There was up to 17-fold variation in annual rates of distal reconstruction between the 12 mainland health boards. The variations in distal reconstruction between the health boards were not reflected in variations in amputation rate nor is the decline in distal reconstruction easily explained by increased angioplasty. CONCLUSIONS: rates of distal arterial reconstruction in Scotland fall well below those in other European countries. It is likely that insufficient distal operations are undertaken to sufficiently impact on amputation rates. The study recommends an increased provision of specialist vascular surgical expertise in Scotland.

Extracranial arterial aneurysms: a cause of crescendo transient ischaemic attacks.

Crescendo transient ischaemic attacks (TIAs) should be regarded as a medical emergency. Patients require hospitalisation with urgent assessment and symptom control with anticoagulant therapy. We report on three patients, all of whom had atherosclerotic aneurysmal disease of the extracranial arterial circulation who presented with crescendo TIAs. The possibility of extracranial aneurysmal disease should always be considered and excluded.

Meeting the needs of women living with HIV.

HIV research, treatment, and support programs in North America have been based on the premise that HIV is a gay man's disease. HIV also affects women. The purposes of this study were to: (1) examine the feelings, concerns, and needs of HIV infected women in a mid-sized Canadian city; and (2) determine whether a community agency for HIV positive persons was adequately supporting women. With informed consent, HIV positive women attending the community agency or a regional medical care facility were interviewed using qualitative research methods to elicit their lived experience. Eight women were interviewed (20% of the women who are HIV positive in this center). Four areas of concern were identified: (1) the impact of diagnosis on women and their children; (2) need for supports specific to HIV positive women; (3) differences in needs and supports available to men and women; and (4) lack of comfort with, or knowledge about, currently available facilities. These results are consistent with previously reported research. HIV positive women who are neither drug-users nor promiscuous feel stigmatized and less supported than HIV positive males. Recommendations for practice included: formulation of self-help groups for women, a more female friendly atmosphere, presence of female staff and other HIV positive women to support these women, and improved inter-agency cooperation. Many recommendations have been implemented and exceeded. The community agency now includes a child's play area, the hiring of a female social worker, and the establishment of an off-site support group for HIV positive women.
