Home Advantage

The present study investigated the effects of season game number, series game number, length of home stand, length of visitor's road trip, home travel, and visitor travel on the home advantage in minor league Double A baseball (N= 1812 games). Initial analysis indicated that the home team won 55.1% of the games (p<.001). Forced-entry multiple regression analyses determined that the combined main and interaction effects of the predictor variables explained less than 1.2% of the variance in win/loss outcome (p>.49). Chi-square analyses revealed that the variable of length of visitor's road trip produced the greatest change in the magnitude of home advantage. When the length of visitor's road trip was cross-tabulated with the length of home stand, me change in home advantage was statistically significant for the home team's later series (p<.05). The implications of these results for the various home advantage explanations are discussed, and future directions for home advantage research are offered.

The Aesthetic

What are the comparative contributions of composer and librettist to the aesthetic impact of great operas? This question was empirically answered using a sample of 911 operas by fifty-nine composers. The aesthetic success of each opera was gauged by a composite measure that included performance and recording frequencies as well as archival indicators. The predictor variables were both idiographic (e.g., the specific identities of the librettists and the literary sources) and nomothetic (e.g., literary genre, language, librettist's age, and experience). After introducing appropriate control variables, the multiple-regression analyses demonstrated that composers play a much bigger role in determining operatic impact than do librettists or their libretti. The identity of the composers alone accounted for almost half of the variance in aesthetic success. As far as opera is concerned, the music is aesthetically more crucial than are the words.

Criterion Variables

Twelve variables previously shown to predict hypnotic susceptibility were factor, analyzed. Six of them loaded on a common factor labeled “a positive set toward, imagining.” The items from two hypnotic susceptibility scales were also factor, analyzed, and fell into three factors (one “cognitive” and two motor factors)., Multiple regression analyses using the susceptibility scales and also the three, susceptibility factors as criterion variables indicated that most of the predicted, variance was accounted for by the predictor variables that loaded on the, “imaginative set” factor. Many of the predictor variables did not contribute, significantly to the prediction of the susceptibility measures. Moreover, a number of, predictors, that purportedly assess similar processes, failed to intercorrelate, significantly. Methodological and theoretical implications of these findings are, discussed.

A total of 15 intellectual and 12 sensory-motor variables were examined as predictors of brain damage in a neurological population with cerebrovascular accidents. Results obtained via Student's t tests and multiple regression analyses demonstrate that it is possible to predict brain damage significantly in this clinical population. Specific conclusions were: (1) as single predictor variables, sensory-motor measures are superior to intellectual measures; (2) brain damage as measured behaviorally is consistent across patient populations in neurological, psychiatric, and neurological sub-groups with CVA; and, (3) multiple variant prediction holds promise for diagnosis of brain damage in a CVA population.

A total of 15 intellectual and 12 sensory motor variables were examined as predictors of brain damage in a neurological and a psychiatric population. Results obtained via Student's t tests and multiple-regression analyses demonstrate chat it is possible to predict brain damage in both clinical populations. Specific conclusions were: (1) as single predictor variables, sensory motor measures are superior to intellectual measures, (2) brain damage as measured behaviorally is consistent across the two populations, (3) there is a greater incidence of false positives in a psychiatric than a neurological population, and (4) multiple-variant prediction seems to hold promise for identification of brain damage.

Home Advantage

Home advantage (HA) is the tendency for sporting teams to perform better at their home ground than away from home, it is also influenced by the crowd support, and its existence has been well established in a wide range of team sports including rugby union. Among all the HA determinants, the positive contribute of the crowd support on the game outcome can be analyzed in the unique pandemic situation of COVID-19. Therefore, the aim of the present study was to analyze the HA of professional high-level rugby club competition from a complex dynamical system perspective before and during the COVID-19 pandemic. HA was analyzed in northern and southern hemisphere rugby tournaments with (2013–2019) and without (2020/21) crowd support by the means of the exhaustive chi-square automatic interaction detection (CHAID) decision trees (DT). HA was mitigated by the crowd absence especially in closed games, although differences between tournaments emerged. Both for northern and southern hemisphere, the effect of playing without the crowd support had a negative impact on the home team advantage. These findings evidenced that in ghost games, where differences in the final score were less than a converted try (7 points), HA has disappeared.

The Individual

This investigation examined the extent to which perceptions of competence and importance predicted self-esteem. Players (N = 214) from three grade levels (3–4, 5–6, 7–8) completed questionnaires that assessed perceived basketball competence, as well as each player’s perception of how important it was to himself, his parents, his coach, and his team to be good at basketball. Three nonstepwise multiple regression analyses revealed that the set of predictor variables accounted for 20–28% of the variance in self-esteem across grade levels. The individual predictor variables significantly related to self-esteem were perceived competence and perceived parent importance for Grades 3–4, perceived competence for Grades 5–6, and perceived competence and perceived team importance for Grades 7–8. Perceived competence, however, consistently contributed most substantively to the prediction of self-esteem. These findings are discussed in relation to earlier studies and existing conceptual frameworks.

Single Predictor

Four linear multiple—regression analyses were used to determine the best composite for predicting scale values of language development derived from children of four different age categories. For the youngest age group (mean age of four years, seven months), a new measure of language development was evaluated. The results showed that the relationship among the predictor variables change as a function of age. Little systematic relationship was observed between the criterion, scale values of language development, and the predictor variables for children above the age of approximately five years. For children who were younger than five years, the best single predictor was the new measure, a modified length-complexity measure. Until there is further improvement of the length-complexity measure, however, mean length of response is a satisfactory predictor of language for children who are approximately five years of age and younger.

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD—with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.

To describe the experience of the Italian Program to Enhance Relations and Communication Skills (PERCS-Italy) for difficult healthcare conversations. PERCS-Italy has been offered in two different hospitals in Milan since 2008. Each workshop lasts 5 h, enrolls 10–15 interdisciplinary participants, and is organized around simulations and debriefing of two difficult conversations. Before and after the workshops, participants rate their preparation, communication, relational skills, confidence, and anxiety on 5-point Likert scales. Usefulness, quality, and recommendation of the program are also assessed. Descriptive statistics, t-tests, repeated-measures ANOVA, and Chi-square were performed. A total of 72 workshops have been offered, involving 830 interdisciplinary participants. Participants reported improvements in all the dimensions (p < 0.001) without differences across the two hospitals. Nurses and other professionals reported a greater improvement in preparation, communication skills, and confidence, compared to physicians and psychosocial professionals. Usefulness, quality, and recommendation of PERCS programs were highly rated, without differences by discipline. PERCS-Italy proved to be adaptable to different hospital settings, public and private. After the workshops, clinicians reported improvements in self-reported competencies when facing difficult conversations. PERCS-Italy’s sustainability is based on the flexible format combined with a solid learner-centered approach. Future directions include implementation of booster sessions to maintain learning and the assessment of behavioral changes.
