<p>Provision for adolescent mental health in New Zealand is in its infancy. CRHS-City is the first Ministry of Education funded initiative that addresses adolescent mental health and transition back to school in New Zealand. This thesis examines the experiences of students and their families attending CRHS-City and how they were supported to transition back to school or further education. This research is important as it focuses on a growing need and documents Central Regional Health School’s attempt to address it. The methodological approach was a multiple case study underpinned by a constructivist paradigm. A qualitative approach was appropriate for this study as the research wanted to capture the impact attending CRHS-City had on a specific group of students and their transition back to a regular school or further education. Three students and their families identified they would be willing to be interviewed as part of this study. Eight overarching themes emerged from the research. Participants described positive outcomes from their experience of attending CRHS-City. This study has found being at CRHS-City helped the participants explore different ways of managing their mental health condition and gain confidence in their abilities to do so, which in turn supported the overall goal of a return to school or further education. However this was not an easy process for either the students or their parents. The findings from this research identified recommendations specific to CRHS-City and for the education sector in general to support students who have a mental health condition continue with their education goals. Support for the student’s family and the regular school is an essential part of this process. Research into effective interventions within mainstream schools to support students who have mental health needs is seen as a logical next step.</p>

In order to conduct a further in-depth exploration of the role of temperature-related parameters in the condition monitoring of wind turbines, this paper proposes a method to assess the condition of wind turbines by analyzing the supervisory control and data acquisition system temperature-related parameters based on existing research. A prediction model of time-sequence regression is established, based on the key temperature signals of WTs, so as to reflect their health condition in the form of prediction residuals. A kind of health index from the perspective of temperature-related parameters is developed by separating the statistics concerning the conformity of the predicted values of key temperature parameters within a certain time window from the measured values in order to clearly present the implied information on the health condition of wind turbines contained in the model prediction residuals. The case study shows that the trend of health index from the perspective of temperature-related parameters is consistent with the health condition of wind turbines. In some instances, its decline obviously occurs earlier than the maintenance provided to address the stoppage, suggesting that such indexes can effectively reflect some early health problems of the wind turbines to provide a reference for their scientific maintenance.

This paper presents a new method for calculating the insulation health index (HI) of oil-paper transformers rated under 110 kV to provide a snapshot of health condition using binary logistic regression. Oil breakdown voltage (BDV), total acidity of oil, 2-Furfuraldehyde content, and dissolved gas analysis (DGA) are singled out in this method as the input data for determining HI. A sample of transformers is used to test the proposed method. The results are compared with the results calculated for the same set of transformers using fuzzy logic. The comparison results show that the proposed method is reliable and effective in evaluating transformer health condition.

IntroductionPatient-reported outcome measures (PROMs) allow patients to self-report the status of their health condition or experience independently. A key area for PROMs to contribute in building the evidence base is in understanding the effects of using person-generated health data (PGHD), and using PROMs to measure outcomes of using PGHD has been suggested in the literature. Key considerations inherent in the stroke rehabilitation context makes the measurement of PGHD outcomes in home-based poststroke rehabilitation, which uses body-tracking technologies, an important use case.ObjectiveThis paper describes the development of a preliminary item bank of a PROM-PGHD for Kinect-based stroke rehabilitation systems (K-SRS), or PROM-PGHD for K-SRS.MethodsThe authors designed a method to develop PROMs of using PGHD, or PROM-PGHD. The PROM-PGHD Development Method was designed by augmenting a key PROM development process, the Qualitative Item Review, and follows PROM development best practice. It has five steps, namely, literature review; binning and winnowing; initial item revision; eliciting patient input and final item Revision.ResultsA preliminary item bank of the PROM-PGHD for K-SRS is presented. This is the result of implementing the first three steps of the PROM-PGHD Development Method within the domains of interest, that is, stroke and Kinect-based simulated rehabilitation.ConclusionsThis paper has set out a case study of our method, showing what needs to be done to ensure that the PROM-PGHD items are suited to the health condition and technology category. We described it as a case study because we argue that it is possible for the PROM-PGHD method to be used by others to measure effects of PGHD utilisation in other cases of health conditions and technology categories. Hence, it offers generalisability and has broader clinical relevance for evidence-based practice with PGHD. This paper is the first to offer a case study of developing a PROM-PGHD.

Abstract Non-forest tree stands are important habitats for many species of birds in the agricultural landscape. They are also the main habitat of the Syrian Woodpecker Dendrocopos syriacus, whose numbers have been decreasing in recent years in some parts of Europe. Recognition of the habitat requirements of this species may help better planning of its protection in the context of the treed agricultural landscapes. During this study, the habitat preferences of the Syrian Woodpecker were determined in the agricultural landscape of South-Eastern Poland. A set of 12 habitat parameters of tree stands located in the breeding territories of the Syrian Woodpecker (n = 122) and in randomly chosen control areas (n = 122) located outside the range of the breeding territories of this species were characterized. The number and species diversity of trees was significantly higher in stands located in Syrian Woodpecker territories than in the random control areas. Stands occupied by breeding pairs also had trees of worse health condition and a larger proportion of fruit trees. The model best explaining the probability of the occurrence of the species indicates that the Syrian Woodpecker requires mainly the presence of tree stands with a greater species diversity of trees, as well as tree stands in worse health condition. When planning the protection of this species’ habitats in the agricultural landscape, the characteristics of non-forest tree stands noted above should be taken into account.

This paper engages with new materialist theory to reimagine transdisciplinary health research. In particular, we draw upon Karen Barad’s theory of agential realism and concept of apparatus to rethink the processes of doing transdisciplinary research. A Baradian inspired approach to transdisciplinarity encourages us to not only explore ways of knowing health phenomena differently by working across disciplines, but also to pay close attention to the politics and practices in such research. We offer a case study based on a two-year transdisciplinary research project focused on the health condition known as Low Energy Availability (LEA) in sportswomen. Through this case we highlight three key ways that Barad’s concept of apparatus helped us know transdisciplinarity differently: (1) Reading disciplines through each other, (2) Intra-actions and the everyday performativity of disciplinary boundaries, and (3) Troubling the boundaries of the apparatus. Ultimately this paper illustrates the value in feminist new materialist conceptual tools for encouraging different questions of transdisciplinary research as ethico-onto-epistemological practices, processes, and politics of knowledge production.

A physical asset’s health is the consequence of a series of factors, ranging from the characteristics of the location where it operates to the care it is submitted to. These characteristics can influence the durability or the horizon of the useful life of any equipment, as well as determine its operational performance and its failure rates in the future. Therefore, the assessment of the influence of asset health on Life Cycle Costs is a compelling need. This paper proposes the incorporation of a factor that reflects the projected behavior of an asset’s health index into its corresponding Life Cycle Costing (LCC) model. This allows cost estimates to be made more realistic and LCC models to be operated more accurately. As a way of validating this proposal, a case study is shown. The methodology proposed in this case study was applied in a real case, considering an LNG facility located in central Chile. In addition, sensitivity studies and comparisons with the results obtained by a traditional Life Cycle Costing model are included. The results show the usefulness of incorporating asset health aspects into the Life Cycle Costing of physical assets.
