The second leg home advantage: evidence from European football cup competitions

The home advantage is a widely acknowledged sporting phenomenon, especially in association football. Here, we examine the second leg home advantage, an effect that is discussed in the public domain but which has received very little scientific attention. The second leg home advantage effect occurs when on average teams are more likely to win a two-stage knock-out competition when they play at home in the second leg. That is, both teams have a home advantage but this advantage is significantly greater for the team that plays at home second. Examining data from three different European Cup football competitions spanning 51 years, we show that the second leg home advantage is a real phenomenon. The second leg home team has more than a 50% probability to qualify for the next round in the competition even after controlling for extra time and team ability as possible alternative explanations. The second leg home advantage appears, however, to have decreased significantly over the past decade. Possible reasons for its existence and subsequent decline are presented.

Economics of cultural tourism: issues and perspectives

The special issue aims at exploring, with an economic perspective, the interconnections between cultural participation, in all its expressions, and tourism organization and patterns with the purpose of understanding economic effects, emerging trends and policy implications. The expanding notion of the cultural consumption of tourists makes the definition of cultural tourism increasingly elusive. Empirical investigations of the relationships between cultural participation and cultural heritage and tourism offer interesting hints in many directions. This introduction briefly overviews the premise of this special issue, the literature and the several perspectives taken by the included articles. Aside from their cultural topics—general, intangible or temporary—these essays all tackle some important economic dimensions of tourism. We encourage cultural economists to invest more in these fascinating areas as more than just intellectual tourists.     

Decreasing “obscene” language of behaviorally disordered children through the use of a DRL schedule

The purpose of the present study was to determine the value of DRL schedules in reducing the behavior of a group of behaviorally disordered children. During the DRL procedure, reinforcement was made available for inappropriate language that was less than a prescribed limit for each day. When the DRL limit was successively decreased across weeks, the behavior of the students systematically decreased. Data indicated that reinforcing low rates of behavior may be an effective alternative to the use of aversive contingencies to reduce the misbehavior of such children.     

Factor analysis of WISC-R scores for children identified as learning disabled,educable mentally impaired,and emotionally impaired

The WISC-R scores for groups of children identified by school personnel as needing special education services were factor analyzed according to type of classification. WISC-R factor loadings were obtained for the scores of children labeled Learning Disabled, Educable Mentally Impaired, and Emotionally Impaired, as well as groups labeled Other and None. Overall, results show the WISC-R to be factorially similar for all groups, with two principal factors emerging which correspond to the Verbal-Performance structure of the test. Significance tests among mean scale scores and IQ scores yielded few meaningful differences across groups.     

Race differences on the developmental test of Visual Motor Integration,the Slosson Intelligence Test,and the ABC Inventory

Preschoolers' scores on the Developmental Test of Visual Motor Integration (VMI), the Slosson Intelligence Test (SIT), and the ABC Inventory (ABCI) were analyzed for race and sex differences. Separate ANOVAs revealed no race effect on the VMI, whereas race differences favoring whites were found for the SIT and ABCI. There were no effects for sex on any measure, nor were there any interactions. Results are discussed in terms of the inconsistent findings for race effects in the perceptual-motor literature.     

Reliability and validity of speech rating scales: Some error effects

Validity and reliability are important criteria in speech rating scale development and use. This investigation explores the effects of certain rater errors, compares a newly devloped scale to a widely used instrument, and suggests the existence of specific factors as crucial elements in evaluation.
