The characteristics of the macro- and trace element composition of the hair in the peoples of Asia, Africa and Latin America

Macro- and trace element composition of hairs on the head, chest, in the armpits, and on the pubis in the population of Asia, Africa, and Latin America adapted and not to the climate, geographic and ecological conditions of the Russian Federation (Moscow) is studied by spectrography (DPS-13 spectrograph). Element composition of residents of 16 countries is analyzed by variation statistics methods using PC: Lebanon, Syria, Yemen, Bahrain, India, Sierra Leone, C?te d'Ivoire, Rwanda, Kenya, Sudan, Mexico, Ecuador, Bolivia, Brasilia, Columbia, and Chile. Hairs from residents of East Europe (Russians, Byelorussians, Ukrainians) living in Moscow for 6-8 years (adapted) were the reference for comparison. A total of 371 specimens of hairs were examined. Hairs from adapted and not adapted residents of the above-listed countries and continents differ significantly from each other and from the hairs of Russians, Byelorussians, and Ukrainians living in Moscow.     

Estimating mortgage prepayments and defaults in older federally assisted rental housing and the possible costs of preventing them

Abstract

An issue now facing the federal government is whether and, if so, how to intervene to prevent mortgage prepayments and defaults on federally assisted low‐income rental units. This paper presents the preliminary estimates of the potential scope of the problem in terms of the possible incidence and timing of these actions, and the costs of preventing them. The estimates are based on modified versions of the model developed for the National Low Income Housing Preservation Commission's study, Preventing the Disappearance of Low Income Housing.

An intermediate version of the modified model predicts 45 percent fewer defaults, 154,000 versus 280,000 units, and 45 percent lower total costs for preventing defaults, $4.6 billion versus $8.4 billion. On the other hand, 16 percent more prepayments are predicted, 283,000 versus 243,000 units. Estimated total costs for preventing prepayments are 17 percent lower, however — $8.5 billion versus $10.3 billion.

Assessing Readiness to Change among Perpetrators of Intimate Partner Violence: Analysis of Two Self-report Measures

Recent interest in the construct of motivation to change among male perpetrators of intimate partner violence (IPV) has led to development of two self-report measures of this construct: the University of Rhode Island Change Assessment for Domestic Violence (URICA-DV; Levesque et al. 2000) and the Safe at Home Inventory (SAH; Begun et al. 2003). We examined the internal structure of these instruments using confirmatory and exploratory factor analyses in a sample of 199 male IPV perpetrators waiting to begin court-mandated batterer intervention programs. Results indicated that the scales had adequate internal consistency. However, using confirmatory factor analyses, the hypothesized structural models of each instrument fit the data poorly. Subsequent models suggested by a series of exploratory factor analyses failed to improve model fit substantially for both scales. For the URICA-DV, a 3-factor model including items from the Precontemplation, Contemplation, and Action subscales fit the data adequately. No acceptable model fit could be found for the SAH. Intercorrelations among similar subscales across the two inventories suggested only a modest degree of intercorrelation (r’s = 0.16–0.52), and a factor structure more dependent on scale of origin than item latent content, suggesting that the scales assess different facets of the readiness to change construct. These results suggest that before the stages of change construct can be fully applied to the IPV area, more research and evaluation are needed on how to accurately assess abuser readiness to change.
