Response Speed as a Function of Different Reinforcement Conditions and a Ready Signal

80 preschool children were each administered 40 trials on a key-pressing apparatus. Marbles served as reinforcers. So given a ready signal performed faster than So not given a ready signal. There was no difference in the mean speeds of the partial reinforcement and the varied delay groups, but both of them performed faster than the constant delay group. The continuously and immediately rewarded group performed faster than the other three groups. The effect of a particular reward condition manifested itself on the immediately following trials. Interpretation in terms of competing responses was offered

Healing Images: A Historical Outline of their Use in Western Medical and Psychotherapeutic Traditions

The ancient literature of numerous cultures abounds with accounts of spectacular cures resulting from the imaging process. These accounts are now being corroborated by a growing body of clinical and experimental evidence. The effectiveness of mental imagery in the treatment of a wide variety of problems has been convincingly documented (Sheikh, 1983). This paper outlines the use of imagery in Western medical as well as psychotherapeutic traditions. It concludes with a discussion of the reasons that make imagery an excellent healing agent

We are bitter, but we are better off: Case study of the implementation of an electronic health record system into a mental health hospital in England

In contrast to the acute hospital sector, there have been relatively few implementations of integrated electronic health record (EHR) systems into specialist mental health settings. The National Programme for Information Technology (NPfIT) in England was the most expensive IT-based transformation of public services ever undertaken, which aimed amongst other things, to implement integrated EHR systems into mental health hospitals. This paper describes the arrival, the process of implementation, stakeholders' experiences and the local consequences of the implementation of an EHR system into a mental health hospital

Rotational alignment near N=Z and proton-neutron correlations

The effects of the residual proton-neutron interactions on bandcrossing features are studied by means of shell model calculations for nucleons in a high-j intruder orbital. The presence of an odd-nucleon shifts the frequency of the alignment of two nucleons of the other kind along the axis of rotation. It is shown that the anomalous delayed crossing observed in nuclei with aligning neutrons and protons occupying the same intruder subshell can be partly attributed to these residual interactions.Comment: 14 pages, including 5 eps figures submitted to Phys.

Symmetry Breaking by Proton-Neutron Pairing

The symmetries of the $t=1$ and $t=0$ pair-fields are different. The consequences for rotational spectra are discussed. For $t=1$, the concept of spontaneous breaking and subsequent restoration of the isospin symmetry turns out to be important. It permits us to describe the proton-neutron pair-correlation within the conventional frame of pairing between like particles. The experimental data are consistent with the presence of a $t=1$ field at low spin in $N\approx Z$ nuclei. For a substantial $t=0$ field, the spectra of even-even and odd-odd $N\approx Z$ nuclei become similar. The possibility of a rotationally induced $J=1$ pair-field at high spin is considered.Comment: 7 pages 9 figure

Wavelet-based video codec using human visual system coefficients for 3G mobiles

A new wavelet based video codec that uses human visual system coefficients is presented. In INTRA mode of operation, wavelet transform is used to split the input frame into a number of subbands. Human Visual system coefficients are designed for handheld videophone devices and used to regulate the quantization stepsize in the pixel quantization of the high frequency subbands’ coefficients. The quantized coefficients are coded using quadtreecoding scheme. In the INTER mode of operation, the displaced frame difference is generated and a wavelet transform decorrelates it into a number of subbands. These subbands are coded using adaptive vector quantization scheme. Results indicate a significant improvement in frame quality compared to motion JPEG200

Influence of Islam on smoking among Muslims

Smoking prevalence is generally high among Muslims. An awareness of their religious beliefs and rulings might increase the effectiveness of antismoking campaign
