Stability of retrospective reports in depression: traumatic events,past depressive episodes,and parental psychopathology

Research findings based on the retrospective reports of depressed individuals have long been held suspect because of possible negative reporting biases associated with depression. In the present study we assess the stability of retrospective reports of past traumatic events, past depressive episodes, parental depression, and parental substance abuse in a sample of 234 adults whose depression status changed over two assessments conducted one year apart. Depression status was found to affect reporting of number of past depressive episodes and past traumatic events, but not reporting of parental psychopathology. Implications of these findings are discussed for research that relies on the retrospective self-reports of depressed participants.     

Food retailing in the eighties— technological opportunities and social constraints

The closing decades of the 20th century will see radical changes taking place in the socio-economic structure of the U.K.—socially, with the growing displacement of labour due to the increasing use of ‘intelligent machines’ and coincidentally with a continuing reduction in the economically active population: economically, with the growing polarization between the industrial North and the post-industrial South. Such perceived developments, closely related to each other, will demand a positive response from U.K. retailing which could lead to a significant re-structuring of the industry as a whole.     

Shaping the future of retail banking

The first half of this article considers recent developments in the retail banking market and, with the aid of tables, describes the present state of the market. Emphasis is placed on the increased competitiveness of the market with more institutions involved in providing more products than ever before, and with more attention being focused on the unbanked sector of the population. The second half of the article considers the factors which are most likely to influence the ruture development of the market—both external influences such as the political, economic and regulatory environment and factors which lie more directly under the control of the banks themselves, such as the introduction of new services and branching policy. The article ends by stressing the scope for individual banks to pursue distinctive policies in this market in future.     

Effects of neuroticism,extraversion, circadian type and age on reported driver stress

Studies have examined effects of various personality variables, including extraversion and neuroticism, as well as age, on driver stress. However, the effect of the morningness-eveningness dimension (circadian type) on reported driver stress among commuters has not been investigated. This study aimed to assess the influence of circadian type as well as extraversion, neuroticism and age on driver stress. Participants were 101 Australian university administrative staff who completed the Eysenck Personality Questionnaire-Revised, the Morningness-Eveningness Questionnaire, and also morning and evening driving diaries as a state measure of driver stress each weekday for one week. Two standard multiple regressions assessed whether neuroticism, extraversion, circadian type and age predicted reported driver stress for morning and evening drives. Neuroticism, circadian type, and age predicted reported driver stress in the mornings but age mainly predicted driver stress in the evenings. A repeated measures ANOVA isolated differences between circadian types for weekday mornings and evenings. Reported driver stress differed for day of week and time of day according to circadian type. The three-way interaction suggested that driver stress is influenced by circadian type and that factors influence driver stress differentially between mornings and evenings. Circadian type appears to influence when driver stress affects individuals.     

Does the Stock Market Gender Stereotype Corporate Boards? Evidence from the Market's Reaction to Directors' Trades

Attitudes towards male and female managers within organizations are well documented, but how the stock market perceives their relative capabilities is less studied. Recent evidence documents a negative short‐run market reaction to the appointment of female chief executive officers and suggests that female executives are less informed than their male counterparts about future corporate performance. These results appear to dispute the stock market value of having women on corporate boards. However, such short‐run market reactions may retain a ‘gender bias’, reflecting the prevalence of negative stereotypes, where the market reacts to ‘beliefs’ rather than ‘performance’. This study tests for such bias by examining the stock market reaction to directors' trades in their own companies' shares, by measuring both the short‐run and longer‐term returns after the directors' trades. Allowing for firm and trade effects, some evidence is found that, in the longer term, markets recognize that female executives' trades are informative about future corporate performance, although initially markets underestimate these effects. This has important implications for research that has attempted to assess the value of board diversity by examining only short‐run stock market responses.     

Using expected values to simplify decision making under uncertainty

A simulation study examines the impact of a simplification strategy that replaces distributional attribute evaluations with their expected values and uses those expectations in an additive value model. Several alternate simplified forms and approximation approaches are investigated, with results showing that in general the simplified models are able to provide acceptable performance that is fairly robust to a variety of internal and external environmental changes, including changes to the distributional forms of the attribute evaluations, errors in the assessment of the expected values, and problem size. Certain of the simplified models are shown to be highly sensitive to the form of the underlying preference functions, and in particular to extreme non-linearity in these preferences.     

Estimating Consumer Exposure to PFOS and PFOA

Perfluorinated compounds have been used for more than 50 years as process aids, surfactants, and for surface protection. This study is a comprehensive assessment of consumer exposure to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) from a variety of environmental and product-related sources. To identify relevant pathways leading to consumer exposure to PFOS and PFOA a scenario-based approach has been applied. Scenarios represent realistic situations where age- and gender-specific exposure occurs in the everyday life of consumers. We find that North American and European consumers are likely to experience ubiquitous and long-term uptake doses of PFOS and PFOA in the range of 3 to 220 ng per kg body weight per day (ng/kg_bw/day) and 1 to 130 ng/kg_bw/day, respectively. The greatest portion of the chronic exposure to PFOS and PFOA is likely to result from the intake of contaminated foods, including drinking water. Consumer products cause a minor portion of the consumer exposure to PFOS and PFOA. Of these, it is mainly impregnation sprays, treated carpets in homes, and coated food contact materials that may lead to consumer exposure to PFOS and PFOA. Children tend to experience higher total uptake doses (on a body weight basis) than teenagers and adults because of higher relative uptake via food consumption and hand-to-mouth transfer of chemical from treated carpets and ingestion of dust. The uptake estimates based on scenarios are within the range of values derived from blood serum data by applying a one-compartment pharmacokinetic model.     

Corporate planning and control systems in Williams & Glyn's Bank

The paper describes the planning procedures presently existing in Williams & Glyn's Bank. Emphasis is placed on the link between the Corporate Plan and the shorter-term budgets; the Corporate Plan provides the framework within which the budget is compiled and the budget is then used as a means of implementing the plan and monitoring progress. Emphasis is also given to the dissemination of the Corporate Plan both to all staff at Branch Manager, or equivalent level, and above and to members of the National Union of Bank Employees Joint Consultative Committee.Lectures based on this paper have been given to the Organization and Use of the Corporate Planning Process Study Group and to the Yorkshire and Humberside Regional Group; both Groups belong to the Society for Long Range Planning.
