TL;DR: Measures of self-efficacy beliefs have been shown to be the best predictor of individual performance in many disciplines over 30 years as mentioned in this paper, which makes measures of perceived selfefficacy a good indicator for individual performance.

TL;DR: Test results show that the proposed fault diagnosis approach can identify accurately the fault pattern of rolling bearings and evaluate performance degradation of bearings.
Abstract: Considering frequency domain energy distribution differences of bearing vibration signal in the different failure modes, a rolling bearing fault pattern recognition method is proposed based on orthogonal wavelet packet decomposition and Gaussian Mixture Model-Hidden Markov Model (GMM-HMM). The orthogonal three-layer wavelet packet decomposition is used to obtain wavelet packet decomposition coefficients from low frequency to high frequency. Rolling bearing raw vibration signals are firstly decomposed into the wavelet signals of different frequency bands, then different frequency band signals are reconstructed respectively to extract energy features, which form feature vectors as the model input of GMM-HMM. A large number of samples are trained to get model parameters for different bearing faults, then several groups of test data are adopted to verify GMM-HMMs so different fault types of rolling bearings are recognized. By calculating the current state appearance probability of monitoring data in GMM-HMMs, different failure patterns are recognized and evaluated from the maximum probability. Similarly, we establish GMM-HMMs for different grade fault samples and evaluated the performance degradation state. Test results show that the proposed fault diagnosis approach can identify accurately the fault pattern of rolling bearings and evaluate performance degradation of bearings.

TL;DR: In this paper, a phonetic analysis at the intersection of segments and prosodies is presented to compare two popular CEOs, Steve Jobs and Mark Zuckerberg, who are known (from informal observations and formal perception experiments alike) to be more or less charismatic speakers.
Abstract: Our paper presents a phonetic analysis at the intersection of segments and prosodies. We look in detail at the previous finding that high pitch and a clear pronunciation contribute to a speaker's perceived charisma. To that end, we compare two popular CEOs, Steve Jobs and Mark Zuckerberg, who are known (from informal observations and formal perception experiments alike) to be more or less charismatic speakers, respectively. The results of our between-speaker comparison suggest that high pitch not only involves the F0 level but also the timing and shaping of pitch accents, and that a clear pronunciation not only refers to a large vowel space but also to the timing and shaping of consonant patterns in terms of fewer place assimilations and clearly separated voiced and voiceless stops. Perspectives for future research and implications for the training and evaluation of charismatic speech are discussed.

Abstract: The paper presents a case study of two popular US American CEOs. It compares the acoustic vowel space sizes of the more charismatic speaker Steve Jobs and those of the less charismatic speaker Mark Zuckerberg, as part of an initial acoustic step to examine a traditional claim of rhetoric that clearer speech makes a speaker sound more charismatic. Analysing about 2,000 long and short vowel tokens from representative keynote speech excerpts of the two speakers shows that Jobs’ vowel space is, across various segmental and prosodic context factors, significantly larger than that of Zuckerberg, whose vowel space is strongly reduced particularly when addressing investors. The differences in vowel-space size are consistent with the claim of rhetoric that a clear articulation is a key characteristic of a charismatic speaker. The discussion of the results describes further experimental steps required to back up the link between clear pronunciation and speaker charisma.

TL;DR: This study examines at a new level of quantitative detail the intonation and timing properties of charismatic speech by comparing two popular CEOs, Steve Jobs and Mark Zuckerberg, who are known from informal observations and formal perception experiments alike to be more or less charismatic speakers, respectively.
Abstract: This study examines at a new level of quantitative detail the intonation and timing properties of charismatic speech by comparing two popular CEOs, Steve Jobs and Mark Zuckerberg, who are known from informal observations and formal perception experiments alike to be more or less charismatic speakers, respectively. By applying the Fujisaki model we decomposed F0 contours into baseline frequency, phrasal F0 excursions and pitch accent-associated F0 excursions. Timing details are examined by applying Pfitzinger’s model of perceived local speech rate to phone and syllable segmentations. Results suggest that high pitch not only involves generally higher F0 levels, but that these increases in F0 are not the same for every prosodic domain or level of the Fujisaki model. In addition we found significant differences depending on whether customers or investors are addressed.
