Dans cet article. on suggere que les problemes de sCcuritC a fondement politique devraient aussi &tre analyses d'un point de vue psychologique.Puisque les individus evaluent le niveau de sCcuritC a travers des processus cognitifs, les rksultats sont subjectifs. Les representations concernant la securitC sont construites a partir d'une menace perque dans l'environnement, menace que l'individu craint d'avoir du ma1 a affronter. Deux Ctudes poursuivies en Israel. oh le probleme de la securitC est aigu. montrent B quel point les individus vivent diffkremment I'insecurite et indiquent que plusieurs facteurs influencent les representations relatives a la securitk. Ces donnees indiquent que des Cvknements reels, militaires, politiques, ou economiques. doivent Ctre perqus pour devenir un aspect de la realit6 personnelle: les Cvknements exterieurs sont compris et interpret& subjectivement. Notre approche accorde une importance particulikre a la psychologie politique dans I'Ctude des problemes de s6curitC. This paper suggests that politically rooted security problems should also be analysed from a psychological perspective. As individuals evaluate the level of security via cognitive processes, the outcomes are subjective. Security beliefs are formed on the basis of the perception of threat in the environment with which the individual perceives a difficulty in coping. Two studies performed in Israel. where the security problem is acute. illustrate how differently individuals experience insecurity, and how different factors influence beliefs about security. These results indicate that while military, political, or economic events are real, they have to be perceived in order to become part of the individual's reality: external events are subjectively interpreted and understood. This approach assigns special importance to political psychology in studying security problems.Requests for reprints should be sent t o Daniel Bar-Tat. School of Education.

In more than 50% of amaurosis fugax patients under 45 years of age no cause for the episodes of visual loss is identifiable. We have encountered 6 young adults (4 women and 2 men) with episodes of amaurosis fugax associated with elevated levels of antiphospholipid antibodies. Splinter hemorrhages of the nail beds were present in most patients. Treatment with antiplatelet medications and anticoagulants appeared to reduce the frequency of episodes and might prevent central retinal artery occlusions or stroke.

The County Borough of Brighton is a seaside town with a population at the 1971 census of 166,081. This population has fluctuated only slightly. In 1951, the total population was 156,486; in 1961 it was 163,159; in 1966 it was 159,510. Brighton's population contains a large percentage of elderly people; in 1966 there were 25 · 7 per cent of the population over the age of 60, and 18 · 8 per cent were over 65 years old, compared with 18 per cent over 60, and 12 per cent over 65 for England and Wales.

The objective of the described study was to assess the effect of living in a communal settlement in Israel's occupied territories on residents' general feelings of insecurity and related variables. The sample was drawn from three settlements that are similar in size, urban-communal nature, year of establishment, and socioeconomic status, but different in geographic location, political ideology, and extent of exposure to the Palestinian uprising. The results indicate, contrary to the authors' hypothesis, that living in the settlement had little effect on insecurity feelings and most other dependent variables. On the other hand, variables related to the personal rather than the communal context had a significant effect on insecurity feelings. These variables included gender, ethnic origin, level of income, age, having a family member who lived through the Holocaust, level of hawkishness, military service, religiosity, and health problems. Findings are interpreted and considered in the context of the cognitive-relational appraisal theory.

The G4132A mitochondrial variation is associated with familial NA-AION in our pedigree.

SUMMARY Inhibitors blocking coagulation reactions, often called lupus anticoagulants, are readily identifiable but rarely considered as risk factors for cerebral infarction. These inhibitors are inconsistently found in a number of diseases (often autoimmune) and after treatment with ceretain drugs and appear to be closely associated with, or identical to, antibodies to certain phospholipids. We have observed two brothers with these inhibitors who both experienced recurrent cerebral infarctions. Such familial occurrence has rarely been reported. In addition, some other family members were found to have depressed factor XII levels. Using the technique of double immunod illusion, we found that the serum from these brothers formed precipitin lines against certain phospholipid substrates, lending further support to the antiphospholipid nature of this inhibitor.
