Collective efficacy belief, within-group agreement, and performance quality among instrumental chamber ensembles
We examined collective efficacy beliefs, including
levels of within
-
group agreement and
correlation with performance quality, of instrumental chamber ensembles (70 musicians,
representing 18 ensembles). Participants were drawn from collegiate programs and intensive
summer music festivals located in the No
rthwestern and Western regions of the United States.
Individuals completed a 5
-
item survey gauging confidence in their groupâs performance abilities;
each ensembleâs aggregated results represented its collective efficacy score. Ensembles provided
a video
-
r
ecorded performance excerpt that was rated by a panel of four string specialists.
Analyses revealed moderately strong levels of collective efficacy belief and uniformly
high within
-
group agreement. There was a significant, moderately strong correlation bet
ween
collective efficacy belief and within
-
group agreement (
r
S
= .67,
p
< .01). We found no
relationship between collective efficacy belief and performance quality across the total sample,
but those factors correlated significantly for festival
-
based ensem
bles (
r
S
= .82,
p
< .05).
Reliability estimates suggest that our collective efficacy survey may be suitable for use with
string chamber ensembles. Correlational findings provide partial support for the theorized link
between efficacy belief and performance
quality in chamber music settings, suggesting the
importance for music educators to ensure that positive efficacy beliefs become well founded
through quality instruction
Applied Research Automatic Self-Talk Questionnaire for Sports (ASTQS): Development and Preliminary Validation of a Measure Identifying the Structure of Athletesâ Self-Talk
The aim of the present investigation was to develop an instrument assessing the conÂtent and the structure of athletesâ self-talk. The study was conducted in three stages. In the first stage, a large pool of items was generated and content analysis was used to organize the items into categories. Furthermore, item-content relevance analysis was conducted to help identifying the most appropriate items. In Stage 2, the factor strucÂture of the instrument was examined by a series of exploratory factor analyses (Sample A: N = 507), whereas in Stage 3 the results of the exploratory factor analysis were retested through confirmatory factor analyses (Sample B: N = 766) and at the same time concurrent validity were assessed. The analyses revealed eight factors, four posÂitive (psych up, confidence, anxiety control and instruction), three negative (worry, disengagement and somatic fatigue) and one neutral (irrelevant thoughts). The findÂings of the study provide evidence regarding the multidimensionality of self-talk, suggesting that ASTQS seems a psychometrically sound instrument that could help us developing cognitive-behavioral theories and interventions to examine and modify athletesâ self-talk
The analysis of facial beauty: an emerging area of research in pattern analysis
Much research presented recently supports the idea that the human perception of attractiveness is data-driven and largely irrespective of the perceiver. This suggests using pattern analysis techniques for beauty analysis. Several scientific papers on this subject are appearing in image processing, computer vision and pattern analysis contexts, or use techniques of these areas. In this paper, we will survey the recent studies on automatic analysis of facial beauty, and discuss research lines and practical application

Getting to know you: Accuracy and error in judgments of character
Character judgments play an important role in our everyday lives. However, decades of empirical research on trait attribution suggest that the cognitive processes that generate these judgments are prone to a number of biases and cognitive distortions. This gives rise to a skeptical worry about the epistemic foundations of everyday characterological beliefs that has deeply disturbing and alienating consequences. In this paper, I argue that this skeptical worry is misplaced: under the appropriate informational conditions, our everyday character-trait judgments are in fact quite trustworthy. I then propose a mindreading-based model of the socio-cognitive processes underlying trait attribution that explains both why these judgments are initially unreliable, and how they eventually become more accurate
PACRR: A Position-Aware Neural IR Model for Relevance Matching
In order to adopt deep learning for information retrieval, models are needed
that can capture all relevant information required to assess the relevance of a
document to a given user query. While previous works have successfully captured
unigram term matches, how to fully employ position-dependent information such
as proximity and term dependencies has been insufficiently explored. In this
work, we propose a novel neural IR model named PACRR aiming at better modeling
position-dependent interactions between a query and a document. Extensive
experiments on six years' TREC Web Track data confirm that the proposed model
yields better results under multiple benchmarks.Comment: To appear in EMNLP201
Survey on Evaluation Methods for Dialogue Systems
In this paper we survey the methods and concepts developed for the evaluation
of dialogue systems. Evaluation is a crucial part during the development
process. Often, dialogue systems are evaluated by means of human evaluations
and questionnaires. However, this tends to be very cost and time intensive.
Thus, much work has been put into finding methods, which allow to reduce the
involvement of human labour. In this survey, we present the main concepts and
methods. For this, we differentiate between the various classes of dialogue
systems (task-oriented dialogue systems, conversational dialogue systems, and
question-answering dialogue systems). We cover each class by introducing the
main technologies developed for the dialogue systems and then by presenting the
evaluation methods regarding this class
