Win, Place or Show: Gauging the Economic Success of the Renoir and Barnes Art Exhibits

Special art exhibits, sometimes known as``blockbusters', are often thought of as tourism andbusiness generators. This belief is fostered byeconomic impact studies that bravely estimate thetotal gross domestic product or total jobs ``created'by such exhibits. Unfortunately, the enthusiasm of theexhibit promoters often leads them to the uncritical useof methodologies that exaggerate the size of theexhibit's contribution to the local economy. Fortunately, such methodologies are well understoodand corrective measures are available to make theestimates they produce more realistic and useful foradvocacy purposes. This paper presents a comparisonof two studies done in Canada to provide arts managerswith a gauge for realistically forecasting thepotential impact of planned ``blockbusters'.Several Canadian art galleries have recently hostedspecial art exhibits, notably the Renoir Portraits atthe National Gallery of Canada and the BarnesExhibition at the Art Gallery of Ontario. They havesurveyed the visitors to them using a correctivemethodology that enables researchers to determinewhich visitors came to the region only because of theexistence of the exhibit and which would have come tothe region and spent money whether the exhibit existedor not. These data enables researchers to estimatequite accurately the amount of visitor spending thatis actually due to the exhibit. This lower, but morecredible, estimate is very useful in helping promotersobtain exhibit sponsorship from local tourismbusinesses who have become skeptical of theexaggerated claims of economic impact estimates basedon standard survey approaches.     

Interactive Instruction to Prevent Attention Problems in Class

This article reports the development and implementation of a strategy designed to bring persistent attention problems in class (off-task behaviour) under the control of teachers and students. The strategy enables the teacher to recognise the demotivating meaning that a task situation can have for a student. By pinpointing this situation in short dialogues with the student, the teacher encourages the student to make his or her own task proposal with the intention of turning the task into a feasible challenge. The strategy was designed from a cognitive-motivational interpretation of attention problems, and it is given shape in four programs for elementary schools. The theoretical frame of reference, the characteristics of the strategy, and the implementation of the programs are set out. Furthermore, an evaluation study is reported. The results indicate that teachers using the strategy can deal more effectively with students who have task behaviour problems. The students' on-task behaviour in this study increased in units of time from 60–70%. This revised version was published online in July 2006 with corrections to the Cover Date.     

Low-dose exercise training does not influence cardiac autonomic control in healthy sedentary men aged 55-75 years

The purpose of this study was to evaluate the effects of a realistic, feasible, and commonly used fitness training programme on cardiac autonomic control in 14 sedentary men aged 62.0 +/- 6.1 years (mean +/- s). All participants performed a one-year fitness training programme in which training intensity and frequency were specifically chosen to be compliant for the majority of the participants (2-3 sessions per week at moderate intensity). At the same time, a reference group consisting of 15 sedentary age-matched men (age 64.2 +/- 6.5 years) did not change their habitual physical activity. Measurements were performed before and after the training intervention. Cardiac autonomic control was inferred from resting values (supine and standing) of heart rate variability (HRV) computed in the frequency domain over 10-min intervals. Endurance capacity was evaluated during a maximal incremental bicycle ergometer test. In spite of an increase in peak oxygen consumption (VO2peak) by 6.4% after training, heart rate in the training group remained unchanged at rest and at the same metabolic demand. No changes in resting parameters of HRV were shown for either groups or positions. Results from this study provide no evidence of a clinically meaningful increase in the vagal modulation to the sinus node at rest after one year of low-volume and moderate-intensity fitness training in men aged 55-75 years.

On the recovery of discrete probability densities from imperfect measurements

The problem of the estimation of a discrete probability density from independent observations is considered. For a wide class of noises, a method is given for estimating a probability density when the measurements are corrupted by additive noise. This method is shown to be consistent, and several bounds on the error are given. An application to the detection of a (nonparametric) random signal is discussed. Finally, the estimation of a probability density is considered where the measurements are noisy and some of the measurements are incorrect. This situation may arise when a machine collecting the data fails part of the time.     

Dietary protein for athletes: from requirements to optimum adaptation

Opinion on the role of protein in promoting athletic performance is divided along the lines of how much aerobic-based versus resistance-based activity the athlete undertakes. Athletes seeking to gain muscle mass and strength are likely to consume higher amounts of dietary protein than their endurance-trained counterparts. The main belief behind the large quantities of dietary protein consumption in resistance-trained athletes is that it is needed to generate more muscle protein. Athletes may require protein for more than just alleviation of the risk for deficiency, inherent in the dietary guidelines, but also to aid in an elevated level of functioning and possibly adaptation to the exercise stimulus. It does appear, however, that there is a good rationale for recommending to athletes protein intakes that are higher than the RDA. Our consensus opinion is that leucine, and possibly the other branched-chain amino acids, occupy a position of prominence in stimulating muscle protein synthesis; that protein intakes in the range of 1.3-1.8 g · kg(-1) · day(-1) consumed as 3-4 isonitrogenous meals will maximize muscle protein synthesis. These recommendations may also be dependent on training status: experienced athletes would require less, while more protein should be consumed during periods of high frequency/intensity training. Elevated protein consumption, as high as 1.8-2.0 g · kg(-1) · day(-1) depending on the caloric deficit, may be advantageous in preventing lean mass losses during periods of energy restriction to promote fat loss.     

History of abuse and neglect in patients with schizophrenia who have a history of violence

Objective

To determine the prevalence of five forms of abuse/neglect during childhood and adolescence in a group of schizophrenic patients with a history of violence.

Methods

Twenty-eight patients hospitalized in a highly secured psychiatric unit were included. Abuse and neglect during patients’ growth were evaluated with the childhood trauma questionnaire (CTQ). History of substance abuse (consumption of cannabis, and/or alcohol, and/or heroin, and/or cocaine during the year that preceded the hospitalization), incarceration, and death of a close parent were also collected.

Results

We found that 46.4% of patients experienced at least 1 form of abuse and/or neglect during childhood and 21.4% of them had experienced more than 2 forms of abuse and/or neglect. The 2 most frequent forms of neglect and abuse were physical abuse (39.3%) and emotional neglect (17.9%). History of substance abuse was found for cannabis (57.1%), alcohol (57.1%), and cocaine and/or heroin (35.7%). We found that 42.8% of patients had 1 close relative who had died during their growth and that 41.6% of these deaths were violent.

Conclusion

It appears important to systematically search for and assess a history of abuse and neglect during growth in schizophrenic patients with a history of violence, in order to offer specific treatments for this group of patients.     

A synthesis of research on effectiveness of school-based drug prevention programmes / Claves de eficacia de los programas de prevención de consumo de sustancias en el contexto escolar: una meta-revisión

Abstract

Relevant information on effectiveness of school-based drug prevention programmes is available. Despite this, there is still contradictory evidence that makes it necessary to continue to shed light on this issue. Based on a synthesis research method, the aim of this study was to determine the relevant variables that enhance the efficacy of these programmes and to determine the weight of their empirical evidence. Furthermore, several features of the evaluation designs whose variables had been proven effective were examined. A systematic review of periodical literature was conducted, which led us to extract 1,622 papers, of which 17 studies were analysed. An in-depth analysis of these publications led us to identify 29 key variables associated with the efficacy of the programme, which were ranked according to the weight of their empirical evidence. Moreover, the characteristics of the studies included in the review highlighted the need to improve the rigorousness and quality of the evaluation designs in this field.     

Role Distance in Question: When it is No Longer Participating But Winning Which is Important

The purpose of this study, which follows on from previous work, is to show in what ways sport has surreptitiously changed and become more complex, to the extent that its functioning only imperfectly responds to one of the basics of sport as envisaged by Elias: role distance. That is the propensity of the participants to avoid being caught in the game, which is only a game, defining in this way the social distance which classes sports performers and the relationship of their practice to the contingencies and material necessities of life. The choice of this focal point is another attempt to understand what happens when sport, by transforming itself, becomes more than sport or even another type of sport. In other words, here we wish to discover what makes Elias' model incomplete. Although sport is supposed to contribute to the pacification of social relations, there are still a large number of elements, which in sporting practice, and in its most recent developments, cannot be explained by the theory of the ‘civilising process’.     

A System of Student Feedback: Considerations of Academic Staff Taken into Account

As a consequence of the suspension of a system of yearly evaluations of individual courses with student questionnaires, the University of Leuven organised a broad consultation of the academic community focussing on what they expect from a system based on student feedback. The study revealed that this community attaches great importance to a clear definition of the goals of student feedback, improvement and accountability, and a logical translation of these goals into a concrete approach. The study also confirmed the need of academic staff for a concrete response to the importance they give to quality improvement and enhancement besides accountability.
