Caregivers of Stroke Survivors: Exploring the Role of Spousal Caregivers through an Occupational Therapy Lens

The purpose of this qualitative study was to explore the occupational needs of caregivers of stroke survivors and to identify potential implications for occupational therapy’s role with this population. Methods: Focus groups and a semi-structured interview were used to gather an in-depth perspective on caregivers’ needs and level of participation in valued activities. Interactions were recorded and transcribed verbatim. Data analysis included open coding, formulation of categorical patterns, and thematic analysis. Rigor was enhanced through peer review, multiple coders, member checking, and triangulation. Results: Four primary themes emerged: (1) the essential need for additional services and support; (2) the amount of time spent on addressing spouses’ needs resulted in occupational loss; (3) finding new ways to participate in daily life activities; and, (4) an association between the survivor’s level of impairment and the caregiver’s quality of life. Conclusion: Demands of caregiving can lead to changes in roles, responsibilities, and routines. OT practitioners are uniquely qualified to reinstate valued occupations into daily life, formulate balanced routines, and provide client specific supports and resources. OT services could provide strategies to enhance caregivers’ ability to partake in meaningful occupations and resume a balanced lifestyle. More research is needed to determine the occupational needs of caregivers and the effectiveness of caregiver interventions

Radiation hardness qualification of PbWO_4 scintillation crystals for the CMS Electromagnetic Calorimeter

Ensuring the radiation hardness of PbWO_4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The production on an industrial scale of radiation hard crystals and their certification over a period of several years represented a difficult challenge both for CMS and for the crystal suppliers. The present article reviews the related scientific and technological problems encountered

First Measurement of Bose-Einstein Correlations in Proton-Proton Collisions at √s=0.9 and 2.36 TeV at the LHC

Bose-Einstein correlations have been measured using samples of proton-proton collisions at 0.9 and 2.36 TeV center-of-mass energies, recorded by the CMS experiment at the CERN Large Hadron Collider. The signal is observed in the form of an enhancement of pairs of same-sign charged particles with small relative four-momentum. The size of the correlated particle emission region is seen to increase significantly with the particle multiplicity of the event

Transverse-Momentum and Pseudorapidity Distributions of Charged Hadrons in pp Collisions at √s=7 TeV

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at √s=7  TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity dN_(ch)/dη||η|<0.5=5.78±0.01(stat)±0.23(syst) for non-single-diffractive events, higher than predicted by commonly used models. The relative increase in charged-particle multiplicity from √s=0.9 to 7 TeV is [66.1±1.0(stat)±4.2(syst)]%. The mean transverse momentum is measured to be 0.545±0.005(stat)±0.015(syst)  GeV/c. The results are compared with similar measurements at lower energies
