Although relationships have been found between maternal psychological characteristics and cognitive and emotional outcomes in children, the behaviors which may mediate these relationships are seldom examined. This is especially true for adolescent mothers, whose children are thought to be at high risk for adverse outcomes. In this study, adolescent mothers in two special programs completed questionnaires measuring perception of the newborn (Neonatal Perception Inventory), knowledge of influences on child development (Infant Caregiving Inventory), and emotional state (General Health Questionnaire); they were also systematically observed while interacting with their infants in a naturalistic situation. Specific maternal behaviors were found to vary with the age of the mother and of the baby. Mothers with neutral or negative perceptions of their infants touched them less than did mothers with positive perceptions. Degree of emotional disturbance was inversely related to the amount of time that the mother looked at her infant while in physical contact.This research was supported in part by NIH Biomedical Research Support Grant No. BRS 507 RR 05445-19 to Johns Hopkins University School of Hygiene and Public Health.Received her Sc.D. in mental hygiene (comparative behavior) from Johns Hopkins University.

In 2002 Australia experienced widespread drought, with over 70 per cent of the country experiencing serious to severe rainfall deficiencies for the period April to October. During this period images of parched landscapes were frequently shown on television, and the Farm Hand drought appeal launched, with the backing of business, to raise funds to assist drought–affected farmers. Since 1992, Australia has had in place a National Drought Policy based on principles of self–reliance and risk management. This policy reflects the neo–liberal economic policy approach, which has dominated Australian policy since the 1980s. Severe drought tests the will of policy makers to hold to this policy line as agrarian sentiments are stirred and political pressure is brought to bear to change policy settings. This article describes the history of drought policy in Australia and the challenges facing policy makers. 相似文献

To better understand the changing toxicology trends in suicidal drug overdoses in the setting of an increased national trend of multidrug overdoses, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 2008 and 2012 to assess the drug type and current risk factors in suicide deaths. Information on demographics, circumstances, suicide risk factors, toxicology findings, and death certificates was collected and analyzed. Three hundred and forty‐two suicide cases of suicide overdoses were identified. Decedents were predominantly female (61.8%). Scene investigation revealed risk factors including suicide ideation (47.4%), previous suicide attempts (38%), and suicide note (38%). Psychiatric illness was present in 72% of cases, with depression being the most common illness. Chronic pain was seen in 27.2% of cases. Most deaths were attributed to multiple drugs (76%). Utilizing the toxicology information will assist in creating public awareness and provide a framework to support targeted efforts to attempt to prevent future suicides. 相似文献
