Clinical validation of the Chinese Personality Assessment Inventory
No full textThe clinical validity of the Chinese Personality Assessment Inventory (CPAI; F. M. Cheung, K. Leung, et al., 1996) was examined in 2 studies involving a group of 167 male prisoners in Hong Kong and a group of 339 psychiatric patients in China. Elevated scores on the clinical scales were obtained for the clinical samples. Logistic regression analyses confirmed that the CPAI scales were useful in differentiating between male prisoners and the Hong Kong male normative sample and between psychiatric patients and a random sample of normal adults in China. Multivariate analyses of variance results showed significant differences on the CPAI clinical scales and personality scales among subgroups of psychiatric patients with diagnoses of bipolar, schizophrenic, and neurotic disorders. The usefulness of an indigenous personality inventory is discussed.The clinical validity of the Chinese Personality Assessment Inventory (CPAI; F. M. Cheung, K.

Convergent validity of the Chinese Personality Assessment Inventory and the Minnesota Multiphasic Personality Inventory-2: Preliminary findings with a normative sample
No full textWe examined the convergent validity of the Chinese Personality Assessment Inventory (CPAI; Cheung, Leung, et al., 1996), an indigenously constructed measure, by comparing its patterns of correlations with the MMPI-2 (Butcher et al., 2001). A valid sample of 147 Chinese students took both the CPAI and the MMPI-2. Results provide preliminary support for the convergence between most of the CPAI clinical scales and the relevant MMPI-2 scales. The CPAI personality scales further illustrated the patterns of personality features associated with the MMPI-2 scales in a Chinese cultural context. We discuss discrepancies in the correspondence between a number of CPAI and MMPI-2 clinical scales.We examined the convergent validity of the Chinese Personality Assessment Inventory (CPAI; Cheung, Leung, et al., 1996), an indigenously constructed measure, by comparing its patterns of correlations with the MMPI-2 (Butcher et al., 2001).

A wireless multimedia system
No full textThe complexity, robustness, image and speech quality as well as packet multiplexing issues of a reconfigurable multi-media mobile communicator are addressed. The proposed moderate complexity motion-compensated Discrete Cosine Transform (DCT) based image communicator provides an image peak signal-to-noise ratio (PSNR) of 38 dB at an average bit rate of about 25 kbits/s. The speech codec used is a low-complexity 32 kbit/s CCITT G721 standard scheme. Bandwidth efficient 16 or 64level quadrature amplitude modulation (QAM) combined with embedded low-complexity binary Bose-Chaudhuri-Hocquenghem (BCH) forward error correction coding is deployed. The 20-slot packet reservation multiple access (PRMA) scheme used supports an extra 2.4 kbit/s low-rate data channel for each speech user, in addition to providing 5-6 video-phone channels. The ADPCM/DCT/BCH/16-QAM as well as 64QAM schemes provide nearly unimpaired speech and image quality for channel SNRs in excess of 30 dB and 38 dB, respectively

Multiband inverted-f antenna with independent bands for small and slim cellular mobile handsets
No full textCopyright @ 2011The design of a small ultra-thin printed inverted-F antenna (PIFA) with independent control on the resonant frequency bands is proposed. The antenna consists of a slotted radiator supported by shorting walls and a small ground plane. The structure is designed and optimized to operate at 2.09, 3.74 and 5 GHz with achievable bandwidths of 11%, 8.84% and 10%, respectively. These three bands cover the existing wireless communication frequency bands from 1.5-6.8 GHz. Each of the three bands can be controlled independently without affecting the other two bands. The 2.09 GHz band can be controlled to operate between 1.5-2.09 GHz (33.33%), the 3.74 GHz band can be controlled over the range of 3.57-4.18 GHz (15.76%) and the 5 GHz band can be controlled to cover the band from 5.00-6.80 GHz (30.50%). Results of intensive investigations using computer simulations and measurements show that the ground plane and the feed locations of the antenna have marginal effects on the performance of the antenna. The effects of the user's hand and mobile phone housing on the return loss, radiation patterns, gains and efficiency are characterized. The measured peak gains of the prototype antenna at 2.09, 3.74 and 5 GHz are 2.05, 2.32 and 3.47 dBi, respectively. The measured radiation efficiencies for the corresponding three bands are 70.12, 60.29 and 66.24% respectively
