An approach ton-mode components analysis

As an extension of Lastovicka's four-mode components analysis ann-mode components analysis is developed. Using a convenient notation, both a canonical and a least squares solution are derived. The relation between both solutions and their computational aspects are discussed.The first draft was written while Wansbeek was with the Netherlands Central Bureau of Statistics. We thank Jaap Verhees for performing the computations and for many discussions on the subject, John Lastovicka for kindly making available his data to us, and the Editor, the referees, Jeroen Weesie and Pieter Kroonenberg for their useful comments.     

A survey of university counselling in the united kingdom and some observations on evaluation

Universities were surveyed about their counselling services during 1987 using a postal questionnaire. Information is presented from 44 universities and includes the extent of counselling provision in relation to the number of students, the staffing and accountability of the services, the needs of the clients and how they are met, and some theoretical and professional concerns mentioned by the counsellors. Finally, some observations are made on the need for more systematic evaluation of the services.     

Can Philosophy be International?

There is a difference between internationalism in politics and philosophy. This paper takes the position that internationalism is possible in politics but not in philosophy, although it is an objective worth pursuing in both domains.     

A procedure for evaluating portable heart monitors

Portable heart rate monitors are potentially useful for regulating exercise intensity. This paper describes procedures to evaluate these devices while subjects are resting, cycling, or running. Of the five monitors tested, all performed reasonably well while subjects were at rest; however, with one exception, performance deteriorated when the monitors were used during exercise. Even so, depending on the level of accuracy required, some of the monitors remained useful during cycling, but only one monitor was consistently accurate while subjects were running. This evidence indicates that, before selecting a particular monitor, potential users of such equipment should carefully consider many things, including the circumstances under which the equipment will be employed. The procedures reported in this paper should be generally useful in evaluating the performance of a variety of devices for monitoring heart rate.     

Fat, full, and happy: effects of food deprivation, external cues, and obesity on preference ratings, comsumption, and buying intentions.

This study reassesses the relative influence of internal and external cues on the behavior of obese and normal individuals. Specifically, the effects of external cues and food deprivation on preference ratings, consumption, and buying intentions were tested for overweight and normal subjects. Obese subjects were more reactive than normals to external cues as indicated by their eating more and intending to buy more food after viewing food slides as opposed to scenery slides. However, their behavior also changed in response to food deprivation, becoming more negative. The obese showed lower food consumption, lower buying intentions, and lower ratings of both food and nonfood slides in the empty condition compared to the full condition.     

Comparatives,logical structures,and encoding in a transitive inference task

Four- to five-year-old children were asked questions on length involving single or double comparatives in a transitive inference task. The number of comparatives varied within or across pairs. The pairs of sticks were colorcoded. Initial pair-wise discrimination training on four adjacent pairs from a five-stick array with only verbal feedback was followed by tests, without feedback, on all possible pairs. When both comparatives were used, Ss learned adjacent pairs faster and more often reached criterion than when only one comparative term was used in training. In testing, Ss were successful on transitive inference tests only when the double-comparative relation was used within pairs during training. Retraining with visual feedback increased the number of Ss solving the inference test only in this condition. The findings are discussed in terms of how children may use processes other than logical operations to make transitive inferences.     

Effects of a poverty-clients agenda on resource allocations by community decision makers

A coalition of human service agencies in one city used the Concerns Report Method of Basic Needs and Vital Services to obtain information on the concerns of their poverty clients. Results were disseminated to local decision makers of the United Way agency, city commission, and county commission during their annual budget deliberations. Two standard accounting methods were used to compare budget allocations to agencies serving low-income people before and after dissemination of the Concerns Report, to other items in the three budgets, and to allocations to similar agencies in a second city. Allocations to agencies serving those most in need in the experimental community grew 17% faster than the total budget, increased 3.96% in share of total budget, and gained 22% over other allocations following dissemination of the Concerns Report.     

Acute neuropsychological consequences of coronary artery bypass surgery

This study examines a series of coronary artery bypass patients (CABS) for neuropsychological and regional cerebral blood flow (RCBF) changes at 8 days and 8 weeks post surgery. Seventy-three percent were found to have moderate or severe neuropsychological deficits at 8 days post operation and 37% at 8 weeks post surgery. A comparison group of major vascular and thoracic surgery patients was also found to have a significant proportion of neuropsychological deficit following surgery. The RCBF assessments indicated a significant drop in mean RCBF at 8 days post surgery in the coronary artery bypass group which did not persist to 8 weeks. The comparison group showed no changes in RCBF following surgery. The findings suggest different patterns of recovery and origins of the neuropsychological deficit in the two groups and emphasize the need for appropriate control groups in studies examining the cortical effects of extracorporeal circulation. In addition, the project received generous support from the special trustees of the Middlesex Hospital.     

Effects of phenobarbitol on aggressive behaviors in a program of required relaxation: A case study

A naturally occurring experiment of the effects of two dosage levels of phenobarbitol on aggressive behaviors in a program of required relaxation is described. A required relaxation program was initiated as a consequence for throwing and hitting by a 13-year-old developmentally disabled male resident of an institutional cottage. The resident had been receiving 50 mg of phenobarbitol twice per day to control seizure activity for two years prior to the introduction of this program. Aggressive behavior decreased from an average of 7.2 incidents a day during baseline to 1.7 per day after six weeks of the required relaxation program. Following several reported seizures, medical staff increased phenobarbitol dosage to 100 mg twice per day and hitting behavior increased beyond baseline levels. After five weeks at this dosage, medication was returned to 50 mg twice a day and hitting behavior returned quickly to the lower intervention levels, while seizure activity remained stable. All observations of behavior were collected during unstructured and regularly occurring events of the individual's daily life. These data suggested that changes in medication influenced observed changes in behavior.
