Outcomes of Peak,Typical, and Variability in Performance of College Football Teams

Purpose

The purpose of this study was to investigate the typical, peak, and variability in performance of both the offensive and defensive units of college football teams over the course of a season in predicting three objective team-level outcomes (win percentage, fan home game attendance, and bowl game payout).

Design/Methodology/Approach

Data were obtained from an archival sports database for 193 Bowl Subdivision college football teams for three separate seasons.

Findings

When all three types of performance were considered simultaneously, only typical performance significantly predicted win percentage and bowl game payout outcomes, and it explained between 19 % (for bowl game payout) and 49 % (for record) of the variance. All interactions between typical performance and performance variability were non-significant.

Implications

These null results point to a boundary condition in the relationship between performance variability and outcomes: whether the outcome is subject to evaluator attributional processes (e.g., raises, performance evaluations) or is more objective in nature. Although null, the present results question a sometimes implicit assumption that performance inconsistency is detrimental to organizational functioning.

Originality/Value

This is one of the first studies to examine outcomes of peak performance, typical performance, and performance variability at the team level. Additionally, most studies examining the outcomes of such performance use subjective outcomes such as performance ratings, whereas this study provides one of the first examinations using objective outcomes such as bowl game payout.     

Pediatric Sub-specialist Controversies in the Treatment of Congenital Heart Disease in Trisomy 13 or 18

Trisomy 13 and 18 are associated with congenital heart disease. Cardiac palliation has been reported in the literature, but is not usually done in this population. Thus, a multi-disciplinary team may experience controversy in formulating a care plan that includes cardiac intervention. Our objective was to determine differences in recommendations for cardiac intervention in this population between physicians specializing in pediatric cardiac critical care, neonatology, and genetics. A web-based survey was performed between April 2007 and August 2008. This survey evaluated surgical and transcatheter cardiac palliations that had been performed for individuals with trisomy 13 or 18 at the respondent’s institution, the respondent’s recommendations for cardiac intervention in hypothetical symptomatic patients with trisomy 13 or trisomy 18 and the influence of parental preference on these recommendations. Eight hundred fifty-nine responses were obtained from a primarily academic practice setting (59%). Cardiologists were most likely to recommend intervention; low risk interventions were recommended by 32% of cardiologists, 7% of neonatologists and 20% of geneticists. Parental request to intervene resulted in a 3 fold increased in the likelihood of all specialist recommending intervention. Counseling of families frequently occurred by multiple sub specialists (50%) and there was frequently (71%) a difference in opinion. Individuals with trisomy 13 or 18 are receiving cardiac intervention at many institutions. Cardiologists were more likely than geneticists or neonatologists to recommend intervention on all heart lesions other than single ventricle palliation which no specialists recommended. Parental wishes that “everything be done” significantly influenced all specialists’ recommendations.     

Parental burden associated with borderline personality disorder in female offspring

To identify aspects of parental burden associated with borderline personality disorder (BPD), an anonymous internet survey linked to BPD support websites was developed for parents to complete on their BPD offspring and unaffected siblings. The questions cover aspects of the child's life from pregnancy through young adulthood, and query about the impact of the child's BPD on six domains of the parent's life, including physical and emotional health, marriage, job, standard of living, social life, and career trajectory. Additionally, financial burden was assessed with questions pertaining to insurance and out-of pocket costs associated with the BPD disorder. BPD offspring were identified by meeting diagnostic criteria embedded within the survey and having been given a diagnosis of BPD by a professional at some point in their life. We report on 233 female offspring meeting strict criteria for BPD. Parents of daughters with BPD endorsed varying levels of impact on the six domains comprising burden with the largest impact on emotional health which was impacted in over 88% of the respondents. Over 50% of parents endorsed four or greater of the six burden items. Particular aspects of the offspring's BPD symptom profile correlated with intensity of parental burden included including problems in adolescence with acting out behavior (p < .000), property destruction (.003), delusional symptoms (.007), and hallucinatory symptoms (.008). A subgroup of respondents provided data on specific financial expenses. The average and median out-of-pocket expense was $60,087, and $10,000. Insurance costs totaled an average of $108,251 with a mean of $20,000. The average cost per year after diagnosis was $14,606 out-of-pocket and $45,573 billed to insurance. The median cost per year after diagnosis was $3,667 out-of-pocket, and $12,500 billed to insurance. After adjusting for household income, a female proband who had been raped incurred roughly $40,000 more in BPD-related costs, while a diagnosis of conduct disorder led to about $50,000 in additional costs. Parents of female offspring with BPD experience burden in multiple domains of their life and many have incurred substantial financial expense. Increasing awareness of co-morbid conditions in the BPD proband that significantly increase parental burden may be indicators for the provision of increased family support.     

Adaptive disclosure: an open trial of a novel exposure-based intervention for service members with combat-related psychological stress injuries

We evaluated the preliminary effectiveness of a novel intervention that was developed to address combat stress injuries in active-duty military personnel. Adaptive disclosure (AD) is relatively brief to accommodate the busy schedules of active-duty service members while training for future deployments. Further, AD takes into account unique aspects of the phenomenology of military service in war in order to address difficulties such as moral injury and traumatic loss that may not receive adequate and explicit attention by conventional treatments that primarily address fear-inducing life-threatening experiences and sequelae. In this program development and evaluation open trial, 44 marines received AD while in garrison. It was well tolerated and, despite the brief treatment duration, promoted significant reductions in PTSD, depression, negative posttraumatic appraisals, and was also associated with increases in posttraumatic growth.     

Representation of unattended material in memory

The current study addresses how information whose processing was not part of task requirement (unattended) is represented in memory. Using a novel measure, recognition memory for unattended material was assessed twice, once when it appeared with the same (old) attended study target and once with a new target. The data reveal memory for unattended study information only in the old target condition. Results suggest that the entire study event is encoded and represented in a memory trace, which contains both attended target information along with unattended context information. In conclusion, manifestation of unattended memory may be dependent on the presence of old target information at test.     

Attenuated response to methamphetamine sensitization and deficits in motor learning and memory after selective deletion of β-catenin in dopamine neurons

In the present study, we analyzed mice with a targeted deletion of β-catenin in DA neurons (DA-βcat KO mice) to address the functional significance of this molecule in the shaping of synaptic responses associated with motor learning and following exposure to drugs of abuse. Relative to controls, DA-βcat KO mice showed significant deficits in their ability to form long-term memories and displayed reduced expression of methamphetamine-induced behavioral sensitization after subsequent challenge doses with this drug, suggesting that motor learning and drug-induced learning plasticity are altered in these mice. Morphological analyses showed no changes in the number or distribution of tyrosine hydroxylase-labeled neurons in the ventral midbrain. While electrochemical measurements in the striatum determined no changes in acute DA release and uptake, a small but significant decrease in DA release was detected in mutant animals after prolonged repetitive stimulation, suggesting a possible deficit in the DA neurotransmitter vesicle reserve pool. However, electron microscopy analyses did not reveal significant differences in the content of synaptic vesicles per terminal, and striatal DA levels were unchanged in DA-βcat KO animals. In contrast, striatal mRNA levels for several markers known to regulate synaptic plasticity and DA neurotransmission were altered in DA-βcat KO mice. This study demonstrates that ablation of β-catenin in DA neurons leads to alterations of motor and reward-associated memories and to adaptations of the DA neurotransmitter system and suggests that β-catenin signaling in DA neurons is required to facilitate the synaptic remodeling underlying the consolidation of long-term memories.
