Muddying the water or swimming dowstream? A critical analysis of literature reviewing in a phenomenological study through an exploration of lifeworld, reflexivity and role of the researcher.

This paper proceeds from examining the debate regarding the question of whether a systematic literature review should be undertaken within a qualitative research study to focusing specifically on the role of a literature review in a phenomenological study. Along with pointing to the pertinence of orientating to, articulating and delineating the phenomenon within a review of the literature, the paper presents an appropriate approach for this purpose. How a review of the existing literature should locate the focal phenomenon within a given context is illustrated by excerps from the first author's literature review within a descriptive phenomenological study. Also discussed is the important issue of when the researcher should fully enter the attitude of the phenomenological reduction and how this may influence the study

The acquisition of the dative alternation and particle movement by second language learners

This thesis looks at the second language acquisition of the English dative alternation, particle movement and their interaction by native speakers of Micmac. The associated theories of syntactic Markedness, which follows from a theory of Universal Grammar and Case theory are assumed as the basis for this research. The dative alternation is argued to have the unmarked structure [NP PP], as well as the marked structure [NP NP]. The unmarked structure for the verb-particle construction is assumed to be [V-Prt] and any other position of the particle in the sentence is marked. -- Results of a study on the acquisition of these structures indicate that the unmarked forms of the dative alternation and the verb-particle construction are acquired first by second language learners. A greater number of subjects judged unmarked forms more acceptable than marked ones according to the results of an intuitive judgement test and employed more in production than marked structures are. Results on the interaction of these structures show that sentences containing an unmarked contiguous particle and a prepositional dative are judged most acceptable and are widely employed in the production task. Sentences involving a marked verb-particle construction and the marked double-object form of the dative are judged less acceptable and are employed less in production. The results presented in this study support a continuum of markedness for sentences involving both target structures

An evaluation of the progress made towards the implementation of treatment summaries for cancer patients across Wessex

This report details an evaluation of the implementation of treatment summaries for cancer patients across the Wessex Deanery, encompassing Hampshire, Dorset and the Isle of Wight. The service evaluation commenced at the end of September 2015 and this report presents the progress made towards the implementation of cancer treatment summaries (CT) across the Wessex Deanery and service users’ experiences of receiving the TSs from two NHS Trusts in the catchment area. The survey results present the progress that has been made in the first six months of implementation and include descriptive data relating to the progress and process of implementation. The qualitative findings from an analysis of service user experience are presented and the findings from the evaluation are discussed in the context of national policy and the wider literature

Structural associations of symptomatic knee osteoarthritis

Objective Structural changes of osteoarthritis (OA) may occur in the absence of pain. In this study, we aimed to identify histopathologic features that are associated with symptomatic knee OA. Methods Medial tibial plateaus and synovium samples were obtained at the time of total knee replacement (TKR) surgery for OA (advanced OA group) or were obtained postmortem from subjects who had not sought medical attention for knee pain during the last year of life (non-OA control group). To identify features of OA, we compared the patients with advanced OA with the age-matched non-OA controls (n = 26 per group). To identify OA features associated with symptoms, we compared two additional groups of subjects who were matched for severity of chondropathy (n = 29 per group): patients undergoing TKR for symptomatic OA (symptomatic chondropathy group) and postmortem subjects with similar severity of chondropathy who were asymptomatic during the last year of life (asymptomatic chondropathy group). The histologic features of the samples were graded, and immunoreactivities for macrophages (CD68) and nerve growth factor (NGF) in the synovium were quantified. The cellular localization of synovial NGF was determined by double immunofluorescence analysis. Results Advanced OA cases displayed more severe changes in the synovium (synovitis, increased synovial NGF, and CD68-immunoreactive macrophages) and cartilage (loss of cartilage surface integrity, loss of proteoglycan, tidemark breaching, and alterations in chondrocyte morphology) than did the non-OA controls. Synovial NGF was localized predominantly to fibroblasts and to some macrophages. The symptomatic chondropathy group displayed greater levels of synovitis, synovial NGF, and loss of cartilage integrity, in addition to alterations in chondrocyte morphology, than did the asymptomatic chondropathy group (P < 0.05 for each comparison). Conclusion Synovitis, increased synovial NGF, alterations in chondrocyte morphology, and loss of cartilage integrity are features of knee OA that may be associated with symptoms

What Does It Take to Make it to the Polling Station? The Effects of Campaign Activities on Electoral Participation

This study explores the extent to which campaign visibility facilitates electoral participation, using data from first- and second-order elections in Britain. Our contribution to the existing literature is threefold. First, we assess whether the effects of campaign effort are conditioned by marginality, finding that campaign mobilisation gets out the vote regardless of the competitiveness of the race. Second, we look at the relative ability of different campaign activities to stimulate turnout, detecting significant differences. Third, we show that the effects of campaign effort on electoral participation are rather similar in first- and second-order elections. These findings suggest that a greater level of electoral information provided by campaign activities does reduce the costs of voting. Local campaigns play a key role in bringing voters to the polls in marginal and non-marginal races, and at general elections as much as at second-order elections

Molecular expression patterns in the synovium and their association with advanced symptomatic knee osteoarthritis

Objective: Osteoarthritis (OA) is a major source of knee pain. Mechanisms of OA knee pain are incompletely understood but include synovial pathology. We aimed to identify molecular expression patterns in the synovium associated with symptomatic knee OA.Design: Snap frozen synovia were from people undergoing total knee replacement (TKR) for advanced OA, or from post-mortem (PM) cases who had not sought help for knee pain. Associations with OA symptoms were determined using discovery and validation samples, each comprising TKR and post mortem (PM) cases matched for chondropathy (Symptomatic or Asymptomatic Chondropathy). Associations with OA were determined by comparing age matched TKR and PM control cases. Real-time quantitative PCR for 96 genes involved in inflammation and nerve sensitisation used TaqMan® Array Cards in discovery and validation samples, and protein expression for replicated genes was quantified using Luminex bead assay.Results: Eight genes were differentially expressed between asymptomatic and symptomatic chondropathy cases and replicated between discovery and validation samples (P3-fold change). Of these, matrix metalloprotease (MMP)-1 was also increased whereas interleukin-1 receptor 1 (IL1R1) and vascular endothelial growth factor (VEGF) were decreased at the protein level in the synovium of symptomatic compared to asymptomatic chondropathy cases. MMP1 protein expression was also increased in OA compared to PM controls.Conclusion: Associations of symptomatic OA may suggest roles of MMP1 expression and IL1R1 and VEGF pathways in OA pain. Better understanding of which inflammation-associated molecules mediate OA pain should inform refinement of existing therapies and development of new treatments

Porous calcium phosphate glass microspheres for orthobiologic applications

Orthobiologics is a rapidly advancing field utilising cell-based therapies and biomaterials to enable the body to repair and regenerate musculoskeletal tissues. This paper reports on a cost-effective flame spheroidisation process for production of novel porous glass microspheres from calcium phosphate-based glasses to encapsulate and deliver stem cells. Careful selection of the glass and pore-forming agent, along with a manufacturing method with the required processing window enabled the production of porous glass microspheres via a single-stage manufacturing process. The morphological and physical characterisation revealed porous microspheres with tailored surface and interconnected porosity (up to 76 ± 5%) with average pore size of 55 ± 8 µm and surface areas ranging from 0.34 to 0.9 m 2 g −1 . Furthermore, simple alteration of the processing parameters produced microspheres with alternate unique morphologies, such as with solid cores and surface porosity only. The tuneable porosity enabled control over their surface area, degradation profiles and hence ion release rates. Furthermore, cytocompatibility of the microspheres was assessed using human mesenchymal stem cells via direct cell culture experiments and analysis confirmed that they had migrated to within the centre of the microspheres. The novel microspheres developed have huge potential for tissue engineering and regenerative medicine applications. Statement of Significance: This manuscript highlights a simple cost-effective one-step process for manufacturing porous calcium phosphate-based glass microspheres with varying control over surface pores and fully interconnected porosity via a flame spheroidisation process. Moreover, a simple alteration of the processing parameters can produce microspheres which have a solid core with surface pores only. The tuneable porosity enabled control over their surface area, degradation profiles and hence ion release rates. The paper also shows that stem cells not only attach and proliferate but more importantly migrate to within the core of the porous microspheres, highlighting applications for bone tissue engineering and regenerative medicine
