Recently there has been increased interest in the special mental health needs of women. We used data from PRIME-MD 1000 study to assess gender differences frequency disorders primary care settings, and explore potential impact these on health-related quality life (HRQL).One thousand patients (559 women) were interviewed during study, which was conducted at four clinics affiliated with university hospitals throughout eastern United States. Patients completed a one-page questionnaire waiting...

In 1973 homosexuality per se was removed from the DSM-II classification of mental disorders and replaced by category Sexual Orientation Disturbance. This represented a compromise between view that preferential is invariably disorder it merely normal sexual variant. While controversy highly public, more recently related but less public involved what became DSM-III Ego-dystonic Homosexuality. The author presents reformulation issues in diagnostic status homosexuality. He argues at issue value...

Over recent decades, ungulate populations across Europe have undergone a rapid recovery. While this constitutes conservation success, there is increasing concern about their impacts on shared resources with humans. Understanding food choices crucial for predicting such impacts. Numerous studies focused single species or communities at narrow spatial scales. Here, we used 265 published diets from 87 European to investigate patterns of resource use by four common deer (moose Alces alces , red...

Using the newly revised DSM-III-R criteria for substance-abuse diagnoses, we examined dependence syndrome elements among 83 psychiatric patients. The sample included 14 with no history of substance abuse. remainder abused alcohol (52), sedatives (31), hallucinogens (12), stimulants (33), cannabis (44), cocaine or opiates (47).

Abstract Across the northern hemisphere, land use changes and, possibly, warmer winters are leading to more abundant and diverse ungulate communities causing increased socioeconomic ecological consequences. Reliable population estimates crucial for sustainable management, but it is currently unclear which monitoring method most suitable track in multi‐species assemblages.

Pellet counts are widely used to monitor ungulates but rely on the assumption that pellets of different species correctly identified in field. Recent studies question this using DNA barcoding techniques check field identification rates. For Europe, which is undergoing a rapid shift towards more diverse ungulate assemblages, such an assessment still missing. Using 3889 fecal samples from nine four European countries, we found average misidentification rates varied 0.6% for horse (Equus ferus)...

The organic/nonorganic distinction in contemporary classifications of mental disorders such as DSM-III and DSM-III-R has important prognostic treatment implications, because it directs the clinician to pay special attention possibility an underlying "physical" disorder cause disturbance. However, term "organic" raises serious intractable problems, since connotative meaning always returns its historical roots, which imply outmoded functional/structural, psychological/biological, mind/body...

The moose (Alces alces) is a dominant large mammalian herbivore in the world's boreal zones. Moose exert significant browsing impacts on forest vegetation and are therefore often at centre of wildlife-forestry conflicts.

Abstract Animals representing a wide range of taxonomic groups are known to select specific food combinations achieve nutritionally balanced diet. The nutrient balancing hypothesis suggests that, when given the opportunity, animals foods particular target balance, and that occurs between meals days. For wild ruminants who inhabit landscapes dominated by human land use, imbalanced diets can result from ingesting agricultural crops rich in starch sugar (nonstructural carbohydrates [NCs]),...
