Negative cognitive styles, dysfunctional attitudes, and the remitted depression paradigm: A search for the elusive cognitive vulnerability to depression factor among remitted depressives.

Results from studies using a behavioral high-risk design and approximations to it generally have corroborated the cognitive vulnerability hypothesis of depression, whereas results from remitted depression studies typically have not. Suspecting that design features of previously conducted remitted designs likely precluded them from detecting maladaptive cognitive patterns, the authors conducted a study featuring the remitted design that has been successful in studies of a biological vulnerability for depression. Participants' current depressive symptoms, negative cognitive styles (hopelessness theory), dysfunctional attitudes (Beck's theory), and lifetime prevalence of clinically significant depression were assessed. Participants who had remitted from an episode of clinically significant depression had more negative cognitive styles, but not greater levels of dysfunctional attitudes, than did never depressed individuals.

Natural rubber and its synthetic analogue, polyisoprene rubber, production prospects

One of the main features characterizing the contemporary level of civilization is the universal use of motor transport. Over the past 15 years, global production of cars has increased by more than one and a half, exceeding 80 million vehicles per year. The tire industry has been developing at the corresponding rate.     

Teenage status of hyperactive and nonhyperactive learning disabled boys

Three groups of learning disabled boys--hyperactives, normoactives, and hypoactives--were studied in grade school, reevaluated at fourteen. At follow-up, all three groups remained at disadvantage to controls on academic and cognitive measures and on complex reaction time. Half the hyperactives had experienced major conflicts with authority, and over a third of hypoactives exhibited psychologically disturbing behaviors. Mental health of normoactives appeared comparable to controls.
