Collaborative community care management enhancing homecare for people with advanced HIV disease: care planning between nursing and social care consultants, London, United Kingdom

Establishing, assessing and matching needs with available services and client expectations is the essence of joint community care planning, within the new United Kingdom legislation (1). Continuous audit and case review by two fieldworkers have described common themes and recurrent scenarios in community HIV care management within health and social care structures. This poster describes working scenarios, care management practice and care issues encountered by two HIV service consultants: Community Care Coordinator (CCC) and Clinical Nurse Specialist (CNS) within one inner London borough and the coterminous health district, respectively. The community care coordinator for HIV (CCC) within the Islington Neighbourhood Services department provides access to and advice about, the available social and housing services for people living with HIV-related disease. The postholder offers referral to other agencies, a dedicated casework service and an advisory role to field social workers, homecare organisers, community occupational therapists and various social services personnel. A specialist domiciliary home care team is available and operates within the borough's existing generic structure for domiciliary care. The clinical nurse specialist HIV/AIDS (CNS) within Camden and Islington Community Services NHS Trust, provides a consultant nursing service in association with and complimentary to, the existing generic nursing services. The postholder offers clinical support and advice to clients, health and social care professionals, in order to maximise the involvement of primary health care teams in homecare provision. Furthermore, education and training for health care professionals in clinical manifestations, intravenous therapy, treatments and psychosocial care is available within the CNS-led continuing education programme (2). Access to both postholders by field staff is increased through message pager aircall. CCC and CNS work jointly on casework, liaising with and working alongside their colleagues in health and social services structures to provide client care management (3). The case studies presented from monthly audit and case review are recurrent and typical of the workload together with the difficulties associated with trying to maintain quality care with cost-limited community resources, blending generic and specialist services for clients with HIV disease

Hadron Collider Sensitivity to Fat Flavourful Z′Z^\primes for RK(∗)R_{K^{(\ast)}}

We further investigate the case where new physics in the form of a massive $Z^\prime$ particle explains apparent measurements of lepton flavour non-universality in $B \rightarrow K^{(\ast)} l^+ l^-$ decays. Hadron collider sensitivities for direct production of such $Z^\prime$s have been previously studied in the narrow width limit for a $\mu^+ \mu^-$ final state. Here, we extend the analysis to sizeable decay widths and improve the sensitivity estimate for the narrow width case. We estimate the sensitivities of the high luminosity 14 TeV Large Hadron Collider (HL-LHC), a high energy 27 TeV LHC (HE-LHC), as well as a potential 100 TeV future circular collider (FCC). The HL-LHC has sensitivity to narrow $Z^\prime$ resonances consistent with the anomalies. In one of our simplified models the FCC could probe 23 TeV $Z^\prime$ particles with widths of up to 0.35 of their mass at 95\% confidence level (CL). In another model, the HL-LHC and HE-LHC cover sizeable portions of parameter space, but the whole of perturbative parameter space can be covered by the FCC.Comment: 24 pages, 11 figures; v2 Reference

Host Family Speech: An Examination of Stylistic Variation as a Form of Linguistic Accommodation Towards the Speech of Foreign Exchange Students

The theory of linguistic accommodation was originally put forth by Howard Giles in 1973 as a response to William Labov’s “attention paid to speech” theory. While Labov claimed that stylistic variation is motivated by the amount of attention that the speaker is placing on the act of speaking, Giles suggested that the stylistic variation that Labov found in his sociolinguistic interviews was instead caused by the assimilation or harmonization of the interviewees’ speech towards that of their interlocutor (Meyeroff, 2011). This paper intends to corroborate Gile’s theory of linguistic accommodation, by examining the effect of the interlocutor on stylistic variation. To do so, the Spanish of a monolingual Dominican host family is analyzed to identify instances of stylistic variation as a form of linguistic accommodation during interactions with American foreign exchange students, who are non-native speakers of Spanish. Data for this investigation comes from home videos taken by an exchange student during their stay with the Dominican family. An analysis of the data shows that the Dominican host family does employ stylistic variation in order to accommodate the speech of their exchange students. Variation occurs principally in salient phonetic aspects of the host family’s speech, but variation also occurs sparsely in grammatical structures utilized by the host family. Stylistic variation in the speech of the host family members as a form of linguistic accommodation towards the exchange students seems to be intentional and motivated by the innate impulsion to assimilate towards one’s interlocutor

Functional grammar and genre analysis : a description of the language of learned and popular articles

There has been a growing interest in the form and function of academic English, especially among teachers of English as a Foreign Language. `Academic' English, however, covers a variety of genres, including specialist and non-specialist writings across a range of disciplines. Little is known about the linguistic similarities and differences among these genres. This thesis aims to add to the study of academic English by investigating learned and popular articles in the fields of biology, computing and history. The descriptive framework is based mainly on Halliday's functional grammar, although reference is made to other linguistic theories, such as Winter's clause relations. Eighteen articles from the three fields were selected, nine learned articles and nine corresponding popular articles. Extracts from these articles form the small corpus analysed. After an introductory chapter, the second chapter reviews the nature of theme in English, and performs a thematic analysis on the corpus. The third chapter reviews the ideational function of language, and investigates how the language of the corpus articles represents reality. The fourth chapter reviews the interpersonal function of language and investigates this aspect of the corpus. The penultimate chapter comments on discourse patterns in the articles. The conclusion suggests that the similarities and differences between learned and popular articles, and between science and the humanities, are a result of systematic functional variation among genres

Exploring Transition through the Senior Year Experience

Senior year is a busy time for most college students as they are preparing for their upcoming transition into adulthood. They are constantly answering the question “What are you doing after graduation?” This results in many college seniors pulling away from their community in order to focus strictly on their major field of study and less on their upcoming transition (Henscheid, 2008). Senior Year Experience programs are a way colleges can provide intentional programming to support college students throughout this transition into adulthood. The purpose of this study was to explore existing Senior Year Experience programs at other institutions with the intention of implementing a new program at Merrimack College. Focus groups involving senior students at Merrimack were conducted, to explore the resources these students have utilized on campus, and to document what they are most nervous about in their upcoming transition. The findings indicated that a Senior Year Experience or transitional program is necessary at this institution, and that many students requested support in areas such as life skills, counseling, maintaining relationships, and professional etiquette. The conclusion of this study recommends a senior retreat experience to be implemented through collaboration with various offices on Merrimack’s campus

Investigation of critical slowing down in a bistable S-SEED

A simulation of S-SEED switching based upon experimental data is developed that includes the effect of critical slowing down. The simulation's accuracy is demonstrated by close agreement with the results from experimental S-SEED switching. The simulation is subsequently used to understand how the phenomenon of critical slowing down applies to switching of an S-SEED and how the effect on photonic analog-to-digital (A/D) converter performance may be minimized.B.

Mathematically Modeling Synchrotron Radiation

The Stanford Synchrotron Radiation Light Source accelerates electrons to relativistic speeds, creating an electron beam which emits radiation as it bends around the storage ring. The synchrotron radiation produced is valued by scientists for the high powered x-rays it gives off which allow them to study samples at the atomic and molecular level. This project focuses on the mathematical modeling of synchrotron radiation using visible light. The current model used to characterize beam size at SSRL uses a Gaussian approximation for the radiation distribution, which is similar to but distinct from the Schwinger equations that are the theoretical model for the intensity distribution of the beam. The beam size characterization model is complex and takes into account the incoherent depth of field effect by using the Gaussian approximations, which we seek to replace with the Schwinger equations. In order to understand the potential difference in beam size characterization brought about by replacing the Gaussian approximations with the Schwinger equations, we have also taken intensity measurements of the 532 nanometer wavelength component of the beam to analyze the Stokes parameters as well as compare the Schwinger equations to measured data
