Intermittency at Intermediate Energies*
Apart from some misunderstandings of this summer, recent developments have led to considerable progress in this controversial but challenging eld. Intermittency is now established as an eeect in at least two dimensions, where it has turned out to be stronger and cleaner than in one. The eeect is strongest in lh and e + e ? collisions. In hh colisions, where the energy range covered is the largest, the eeect is stronger at intermediate then at high p s. Next to parton showering, intermittency is very sensitive to the soft phase, which will have to be studied with large statistics at intermediate energies, where it is not overshadowed by hard eeects. In terms of the space-time development of a scattering process, the intermittency phenomenon and the determination of its parameters are shown to give a genuine information on the nature of hadronization at large distances compared to the hard interaction region. As such, it is expected to be sentitive to the nuclear environment of a deep-inelastic electron collision. In recent years events have been observed containing high particle density \spikes" in rapidity space. Fig.1a shows the JACEE event 1] at a pseudo-rapidity resolution of =0.1 unit, with local uctuations up to dn== 300 and with a signal to background ratio of about 1:1. The NA22 event 2] of Fig.1b contains a rapidity \spike" of dn=dy=100 at a rapidity resolution y=0.1. This corresponds to 60 times the average density in this experiment. Also UA5 3] has reported \spikes" of dn=dd up to 30 (10 times average) as early as JACEE, but found these to be in agreement with a short range cluster Monte Carlo. No doubt, local density uctuations exist. The question is whether they are of statistical or dynamical origin, whether the underlying probability density is continuous or intermittent. To study these, Biaa las and Peschanski 4] have suggested to study the dependence of scaled factorial multiplicity moments
INTERMITTENCY IN PARTICLE COLLISIONS
Some methods and concepts which are at the origin of and are presently relevant to the study of intermittency in multiparticle reactions are reviewed in an introductory and pedagogical way.
Facilitating Spiritual Care in the Rehabilitation Setting
&NA; Nurses, who traditionally have espoused a holistic approach to patient care, are in a unique position to attend to clients’ spiritual needs. The assessment, planning, and provision of spiritual care is particularly important in the rehabilitation setting. Research attention needs to be directed at gaps in the current state of knowledge and practice of spiritual care to meet the needs of rehabilitation clients.
