A survey of clinical nursing skills in intellectual disability nursing
In this study the question asked is: what clinical nursing skills are predominantly used in intellectual disability nursing? A survey of the nursing needs of people with moderate to severe intellectual disability in both residential and community units was undertaken with a questionnaire.The measure was a Likert design scale ranging across: skills used more than once a day, skills used daily, skills used weekly, skills used monthly, skills very rarely used, and skills never used.The results of the study help to identify, plan, and direct the type and level of nursing skills taught to the intellectual disability nursing students and provides an insight into the current nursing skills used in the intellectual disabilities field
LEP Performance at 91.5 GeV
The 1997 LEP collider run was the first year of the LEP2 program devoted to stable high luminosity running. The good performance of the LEP superconducting RF system allowed to run at beam energies of 91.5 GeV. In addition to the to usual optimisation procedures to minimise the vertical beam emittances, the horizontal beam sizes were reduced by increasing the horizontal damping partition number and reducing the betatron function at the interaction points. Vertical beam-beam tune shifts in excess of 0.05 were achieved with total beam currents of 5 mA. The total integrated luminosity of 73 pb-1 is the highest ever recorded in a single year of LEP operation
'Reaching the hard to reach' - lessons learned from the VCS (voluntary and community Sector). A qualitative study.
Background The notion 'hard to reach' is a contested and ambiguous term that is commonly used within the spheres of social care and health, especially in discourse around health and social inequalities. There is a need to address health inequalities and to engage in services the marginalized and socially excluded sectors of society. Methods This paper describes a pilot study involving interviews with representatives from eight Voluntary and Community Sector (VCS) organisations . The purpose of the study was to explore the notion of 'hard to reach' and perceptions of the barriers and facilitators to accessing services for 'hard to reach' groups from a voluntary and community sector perspective. Results The 'hard to reach' may include drug users, people living with HIV, people from sexual minority communities, asylum seekers, refugees, people from black and ethnic minority communities, and homeless people although defining the notion of the 'hard to reach' is not straight forward. It may be that certain groups resist engaging in treatment services and are deemed hard to reach by a particular service or from a societal stance. There are a number of potential barriers for people who may try and access services, including people having bad experiences in the past; location and opening times of services and how services are funded and managed. A number of areas of commonality are found in terms of how access to services for 'hard to reach' individuals and groups could be improved including: respectful treatment of service users, establishing trust with service users, offering service flexibility, partnership working with other organisations and harnessing service user involvement.
Conclusions: If health services are to engage with groups that are deemed 'hard to reach' and marginalised from mainstream health services, the experiences and practices for engagement from within the VCS may serve as useful lessons for service improvement for statutory health services
Operational procedures to obtain high beam-beam tune shifts in LEP pretzel operation
During the running period 1994 the luminosity of LEP has been improved without colliding higher bunch currents. This paper describes the main procedures used by the operations group for luminosity optimization. Separator scans in the vertical plane and orbit interpolations in the horizontal plane are used to adjust settings for electrostatic separators in order to ensure head-on collisions. The closed orbit is corrected towards a reference orbit (called "golden" orbit) which has been found empirically to produce good luminosity. The settings of the skew quadrupoles for coupling compensation is obtained by measuring the closest tune approach of the horizontal and vertical betatron tunes
Overview of LEP operation in 1998
After the installation of 32 additional RF cavities in the 1997-1998 shutdown LEP was operated at a beam energy of 94.5 GeV. The total integrated luminosity for the year 1998 clearly surpassed its target and reached 198 pb-1. Vertical beam-beam tuneshiftsof more than 0.07 were obtained. The performance did not seem to be beam-beam limited, but the total beam current was limited by power dissipation problems to around 6 mA. A high phase advance optics (102o, 90o), with a smaller natural emittance, was used for regular operation in 1998. This contributed to the excellent performance of LEP, together with the further reduction of both the horizontal and vertical beta function at the interaction points. No dynamic aperture problems were encountered
Report on the Working Group set up to Study the Requirements for Operating the SPS within the INB Framework (INBOPS)
The convention signed with the French authorities for the LHC defines a new Installation Nucléaire de Base (INB). The LHC machine tunnel, the experiments, some buildings which cover access shafts to the machine and the SPS with its extraction lines up to the targets are all inside the new perimeter. The new convention came into effect in September 2000 and therefore the SPS fell within the new context from that time. As a consequence, SL has to operate the SPS within this new regulatory framework and a small working group was set up to look at the requirements and to estimate the resources required. The conclusions of the working group are reported in this paper
LEP1 operation, 1989-1995
In October 1995, the last run foreseen for dedicated Z production at CERN was performed in LEP, thereby bringing to a close the first phase of operation of the machine. A total luminosity of 200 pb-1 has been delivered to each of the four experiments, which together have recorded the decays of over 20 millions Zs. Machine performance has increased to the extent that a good weekend in 1995 saw as much luminosity delivered as in the whole of 1989. This improvement has been made possible by a combination of several things. Over and above general operational expertise, special care went into the treatment and stabilisation of the closed orbit in order to obtain reproducible high performances with vertical beam-beam tune shifts exceeding values of xy = 0.04. Both Pretzel and Bunch Train schemes have been introduced to double the number of bunches, and high-tune optics have been developed to produce low transverse emittances which allow operation at the beam-beam limit throughout physics runs. Included in the integrated luminosity are data taken off the peak of the Z resonance, to allow precise determination of the mass and width of this particle. Accurate measurements of the beam energy during these runs have brought to the fore some unusual effects
High intensity proton beams in a multi-cycled SPS
The SPS ran for 247 days during 1994; 64% of this was with high intensity proton beam for physics data taking in the Fixed Target mode of operation, 12% was for a lead run at the end of the year, with the remaining 24% spent in setting up and machine development. The SPS supplied LEP with 8 bunches of electrons and 8 bunches of positrons either in the 14.4 or 19.2 seconds interleaved cycling mode during the operation with protons or lead ions respectively. The new record peak intensity during the year was 3.9x1013 protons per pulse at 450GeV. A total of 11x1018 proton were delivered to all targets, with an overall average during physics of 2.5x1013 protons per pulse at 450GeV. Some 6x1018 protons were delivered to both neutrino experiments
Experiencing stigma as sex work researchers in professional and personal lives
Researchers have demonstrated the challenges associated with sex work research; negotiating the stigma attached to its subject matter, the perceived dangerousness of participants, and the barriers faced in reaching hidden populations. By reflecting upon our separate research experiences and drawing upon a body of reflexive sex work research, this article explores how, as sex work researchers, we experienced stigma not only in our professional roles as researchers, but also in our personal lives. We apply Goffman's (1968) notion of stigma by association; and consider how stigma often associated with prostitution became transposed onto us. In particular, we compare and contrast our separate experiences of conducting sex work research to demonstrate our similar experiences of stigma by association
