What is the value of mentoring in a small business? Using narrative evaluation to find out

The paper examines the case of one small business manager (Alistair) and the value he gave to a mentoring intervention demonstrated by the use of narrative evaluation. Doubts about the efficacy of orthodox approaches to evaluation when applied to management development activities lead to the view that narratives are more appropriate. Narrative evaluation techniques are applied to a story told by Alistair, the Managing Director of a small business in Sheffield, concerning his view of his involvement in a mentoring programme. Alistair's initial reservations about the value of the programme are revealed rhetorically through a range of arguments. After such doubts, through a process of conversation, the story reveals how Alistair is able to find value from mentoring.     

The use of avoidance training in studies of modulation of memory storage

Studies of the modulatory effects on memory of many treatments have relied in large part on the use of inhibitory (passive) avoidance training procedures. Recent critiques have questioned the validity of data obtained with the inhibitory avoidance task. This paper addresses these comments and describes many of the advantages of using the procedure in studies of processes which regulate the neurobiological mechanisms which store new information.     

Age-Related Changes in Plasma Catecholamine Responses to Acute Swim Stress

Young adult (3 months) and aged (22 months) Fischer 344 male rats were prepared with chronic tail artery catheters. Three days after surgery, rats were exposed acutely to swim stress at 20, 25, 30, or 35°C for 15 min. Blood samples were obtained from each rat under basal conditions, at the end of the swim stress episode, and 15, 30, and 45 min after swim stress. Basal plasma levels of norepinephrine and epinephrine (EPI) were similar for 3- and 22-month-old rats. In contrast, plasma catecholamine responses of aged rats were significantly greater than those of young adult rats following swim stress at 20 and 25°C. Plasma catecholamine responses were similar for rats of the two ages following swim stress at 30 or 35°C. These findings indicate that aged rats have exaggerated sympathetic-adrenal medullary responses to acute swim stress at the lower water temperatures. Given the modulatory effects of plasma EPI on memory, these age-related alterations in plasma catecholamine responses to acute swim stress may influence spatial memory performance of rats in the Morris water maze.     

Daydreaming and curiosity: stability and change in gifted children and adolescents

Developmental differences in daydreaming and curiosity based on cross-sectional data have been reported, but longitudinal data are lacking. Patterns of longitudinal stability and change in two intellectual styles, daydreaming and curiosity, in gifted children and adolescents are described in this paper. Seventy-four intellectually gifted children attended a special program during two consecutive summers. Self-reports of their frequency of and attitudes toward daydreaming and two measures of their curiosity were obtained each year. The findings suggest a pattern of both change and stability in intellectual styles over time. Measures which tap the content of daydreams changed over time, but measures of process or ways of relating to the environment, such as curiosity and frequency of daydreaming, were fairly stable.     

Blood glucose and brain function: interactions with CNS cholinergic systems

We recently found that glucose injections attenuate amnesia and hyperactivity produced by scopolamine, a muscarinic antagonist. The present study examined whether glucose would augment behavioral effects produced by a muscarinic agonist, physostigmine. In experiment I, doses were first determined for which neither glucose (10 mg/kg) nor physostigmine (0.05 mg/kg) altered scopolamine-induced hyperactivity. However, combined glucose-physostigmine injections significantly reduced scopolamine hyperactivity. Experiment II evaluated the effects of glucose on physostigmine-induced tremors. Glucose (10, 100, and 250 mg/kg) or saline injections were given 20 min before physostigmine injections (0.4 or 0.05 mg/kg). Observations of glucose effects on the severity of physostigmine-induced tremors were then obtained at 5-min intervals for 25 min after physostigmine injections. Glucose (100 mg/kg) significantly facilitated the onset of tremors when injected before either dose of physostigmine, and augmented (at 100 and 250 mg/kg) tremor severity when injected before the lower dose of physostigmine. These findings indicate that glucose can facilitate the actions of a cholinergic agonist on two behaviors, locomotor activity and tremors, adding support to the view that circulating glucose levels can modulate central cholinergic function. More generally, the results provide additional evidence that circulating glucose levels can influence brain function.     

A COMPARISON OF VIETNAMESE-AUSTRALIAN AND ANGLO-AUSTRALIAN MOTHERs' BELIEFS ABOUT INTELLECTUAL DEVELOPMENT*

Vietnamese- and Anglo-Australian mothers' beliefs about intelligence and its development were obtained through a structured interview. Twenty-five working-class Vietnamese, 32 working-class and 39 upper-middle-class Anglo mothers of five-year-old children were asked about the heritability and stability of intelligence, its importance in different life domains and the roles of parents and teachers in developing intelligence. Developmental timetables for the acquisition of certain intellectual abilities were also elicited. Culture emerged as a significant influence on mothers' beliefs considerably more than did social class or sex of their child. Vietnamese mothers perceived intelligence as more important than did Anglo mothers, had a more narrowly focused view of education and intellectual development, and expected later acquisition of intellectual abilities. These differences are consistent with traditional Vietnamese values.     

The effects of sensation seeking and misattribution of arousal on attraction toward similar or dissimilar strangers

While previous research has indicated that certain situational variables can mediate the typical positive relationship between attitudinal similarity and attraction, investigations focusing on the impact of individual difference variables on this relationship have typically yielded unimpressive results. The present experiment was conducted to test the prediction that individual differences in sensation seeking do moderate this relationship. The major results showed that, as predicted, high sensation seekers were more attracted than low sensation seekers to dissimilar others, whereas low sensation seekers were more attracted than high sensation seekers to people with similar attitudes. The data also indicated that a misattribution of arousal manipulation serves to increase attraction under certain conditions. Specifically, misattribution of aversive arousal increased low sensation seekers' attraction to a dissimilar stranger and increased high sensation seekers' attraction to a similar stranger.     

The Anatomy of Revolutionists

A questionnaire containing 62 items relating to the New Left and 28 items measuring anomia, authoritarianism, and Machiavellianism was given to 153 entering freshmen at Columbia in the fall of 1968. The five factors emerging from a factor analysis of responses to the items were labeled: New Left Philosophy, Revolutionary Tactics, Machiavellian Tactics, Machiavellian Cynicism, and Traditional Moralism. Students who had been politically active prior to coming to college scored higher than the rest of the group on New Left Philosophy, Revolutionary Tactics, and Machiavellian Cynicism, but scored lower on Machiavellian'Tactics and Traditional Moralism. In the spring of 1969, a revised set of items was given to students in introductory psychology classes at Columbia University and New York University. While the findings from these subjects replicated those found with the Columbia freshmen, they showed subtle differences which led to speculations about the radicalization process. Also discussed are the relationships between the nature of political participation and all of the factors, with special emphasis on the discrepancy between Machiavellian Tactics and Cynicism.
