Gnss and photogrammetric uav derived data for coastal monitoring: A case of study in emilia-romagna, italy
GNSS real-time techniques and UAV photogrammetry can be alternative methods for the monitoring of sand beaches. This activity is particularly important in environments such as the Emilia-Romagna coastline. In this paper, two couples of surveys (year 2019 and 2020) performed using GNSS or a low-cost UAV equipment over a common area were compared in order to analyse: point-wise height differences, profile shapes along defined sections, and volumes variations over time. Both surveys were aligned to the same reference benchmark through GNSS measurements. The highest discrepancies between the two surveying methods (tens of cm) were found in vegetated areas and along the shoreline, otherwise, the height differences are mainly within the 10 cm level. In terms of volumes, excluding the most critical areas, differences close to zero can be found. Obtained results show that GNSS and UAV photogrammetry provides similar results, at least for quite flat terrains and when decimetre-level accuracy is required
Stakeholder views on a recovery-oriented psychiatric rehabilitation art therapy program in a rural Australian mental health service: a qualitative description
BACKGROUND: Recovery-oriented care is a guiding principle for mental health services in Australia, and internationally. Recovery-oriented psychiatric rehabilitation supports people experiencing mental illness to pursue a meaningful life. In Australia, people with unremitting mental illness and psychosocial disability are often detained for months or years in secure extended care facilities. Psychiatric services have struggled to provide rehabilitation options for residents of these facilities. Researchers have argued that art participation can support recovery in inpatient populations. This study addressed the research question: Is there a role for the creative arts in the delivery of recovery-oriented psychiatric rehabilitation for people with enduring mental illness and significant psychosocial disability detained in a secure extended care unit? METHODS: The study had two major aims: to explore the experiences of consumers detained in a rural Australian secure extended care unit of an art therapy project, and to examine the views of nurse managers and an art therapist on recovery-oriented rehabilitation programs with regard to the art therapy project. A qualitative descriptive design guided the study, and a thematic network approach guided data analysis. Ethics approval was granted from the local ethics committee (AU/1/9E5D07). Data were collected from three stakeholders groups. Five consumers participated in a focus group; six managers and the art therapist from the project participated in individual interviews. RESULTS: The findings indicate that consumer participants benefitted from art participation and wanted more access to rehabilitation-focussed programs. Consumer participants identified that art making provided a forum for sharing, self-expression, and relationships that built confidence, absent in the regular rehabilitation program. Nurse manager and the art therapist participants agreed that art participation was a recovery-oriented rehabilitation tool, however, systemic barriers thwarted its provision. CONCLUSIONS: The transformation of mental health services towards a recovery orientation requires commitment from service leaders to provide evidence-based programs. Psychiatric rehabilitation programs based on local need should be included in public mental health services. This study supports the use of art-based rehabilitation programs for people detained in rural secure extended care facilities. Introducing these programs into clinical practice settings can improve the consumer experience and support organisational culture change towards a recovery orientation
Flowing Between Fermionic Fixed Points

fields in AdS. We use this to compute the all-loop beta function for fermionic
double trace operators in the dual conformal field theory.Comment: 21 pages. V2: Acknowledgement added; v3: Typo correcte
Dynamical charge density fluctuations pervading the phase diagram of a Cu-based high-Tc superconductor
Charge density waves are a common occurrence in all families of high critical
temperature superconducting cuprates. Although consistently observed in the
underdoped region of the phase diagram and at relatively low temperatures, it
is still unclear to what extent they influence the unusual properties of these
systems. Using resonant x-ray scattering we carefully determined the
temperature dependence of charge density modulations in
(Y,Nd)BaCuO for three doping levels. We discovered
short-range dynamical charge density fluctuations besides the previously known
quasi-critical charge density waves. They persist up to well above the
pseudogap temperature T*, are characterized by energies of few meV and pervade
a large area of the phase diagram, so that they can play a key role in shaping
the peculiar normal-state properties of cuprates.Comment: 34 pages, 4 figures, 11 supplementary figure
Exploring the Process of Digital Storytelling in Mental Health Research: A Process Evaluation of Consumer and Clinician Experiences
Digital storytelling is an art-based research method that has potential to engage mental health consumers and clinicians in dialogue about their lived experiences. However, few studies have examined the process of digital storytelling and people’s perspectives about making digital stories. In this article, a process evaluation framework is used to explore two digital storytelling workshops conducted with mental health consumers and clinicians. Project planning and implementation documents were collated, and interviews conducted with workshop participants thematically analyzed. Data were combined with facilitator reflections and are reported using a process evaluation framework. Findings indicate that the digital storytelling process is a useful research method that can be used to create a space where power differentials between consumers and clinicians are made visible and shared dialogue can develop. Recommendations from the study include the importance of employing skilled consumer and clinician support personnel to guide the process of participation and negotiate ethical tensions to ensure participant safety
Developing a questionnaire evaluating knowledge, attitudes and behaviors on audit & feedback among general practitioners. A mixed methods study
Background: Audit and Feedback (A&F) is one of the most common strategies used to improve quality in healthcare. However, there is still lack of awareness regarding the enabling factors and barriers that could influence its effectiveness. The aim of this study was to develop a questionnaire to measure the knowledge, attitudes and behaviors of general practitioners (GPs) regarding A&F. The study was performed in the context of the EASY-NET program (project code NET-2016-02364191). Methods: The survey was developed according to two steps. Firstly, a scoping review was performed in order to map the literature on the existing similar instruments with the aim of identifying the sub-domains and possible items to include in a preliminary version of the questionnaire. In the second phase, the questionnaire was reviewed by a multidisciplinary group of experts and administrated to a convenience sample in a pilot survey. Results: Ten papers were included in the scoping review. The survey target and development methodology were heterogenous among the studies. The knowledge, attitudes and behaviors domains were assessed in six, nine and seven studies, respectively. In the first step, 126 pertinent items were extracted and categorized as follows: 8 investigated knowledge, 93 investigated attitudes, and 25 investigated behaviors. Then, 2 sub-domains were identified for knowledge, 14 for attitudes and 7 for behavior. Based on these results, a first version of the survey was developed via consensus among two authors and then revised by the multidisciplinary group of experts in the field of A&F. The final version of the survey included 36 items: 8 in the knowledge domain, 19 in the attitudes domain and 9 in the behaviors domain. The results of the pilot study among 15 GPs suggested a good acceptability and item relevance and accuracy, with positive answers totaling 100% and 93.3% in the proposed questions. Conclusions: The methodology used has shown to be a good strategy for the development of the survey. The survey will be administrated before and after the implementation of an A&F intervention to assess both baseline characteristics and changes after the intervention
The role of clothing in thermal comfort: how people dress in a temperate and humid climate in Brazil
Abstract Thermal insulation from clothing is one of the most important input variables used to predict the thermal comfort of a building's occupants. This paper investigates the clothing pattern in buildings with different configurations located in a temperate and humid climate in Brazil. Occupants of two kinds of buildings (three offices and two university classrooms) assessed their thermal environment through 'right-here-right-now' questionnaires, while at the same time indoor climatic measurements were carried out in situ (air temperature and radiant temperature, air speed and humidity). A total of 5,036 votes from 1,161 occupants were collected. Results suggest that the clothing values adopted by occupants inside buildings were influenced by: 1) climate and seasons of the year; 2) different configurations and indoor thermal conditions; and 3) occupants' age and gender. Significant intergenerational and gender differences were found, which might be explained by differences in metabolic rates and fashion. The results also indicate that there is a great opportunity to exceed the clothing interval of the thermal comfort zones proposed by international standards such as ASHRAE 55 (2013) - 0.5 to 1.0 clo - and thereby save energy from cooling and heating systems, without compromising the occupants' indoor thermal comfort
WARP: a WIMP double phase Argon detector
The WARP programme for dark matter search with a double phase argon detector
is presented. In such a detector both excitation and ionization produced by an
impinging particle are evaluated by the contemporary measurement of primary
scintillation and secondary (proportional) light signal, this latter being
produced by extracting and accelerating ionization electrons in the gas phase.
The proposed technique, verified on a 2.3 liters prototype, could be used to
efficiently discriminate nuclear recoils, induced by WIMP's interactions, and
measure their energy spectrum. An overview of the 2.3 liters results and of the
proposed 100 liters detector is shown.Comment: Proceeding for IDM200
Suzaku measurement of Abell 2204's intracluster gas temperature profile out to 1800 kpc
Context: Measurements of intracluster gas temperatures out to large radii are
important for the use of clusters for precision cosmology and for studies of
cluster physics. Previous attempts to measure robust temperatures at cluster
virial radii failed. Aims: The goal of this work is to measure the temperature
profile of the very relaxed galaxy cluster Abell 2204 out to large radii,
possibly reaching the virial radius. Methods: Taking advantage of its low
particle background due to its low-Earth orbit, Suzaku data are used to measure
the outer temperature profile of Abell 2204. These data are combined with
Chandra and XMM-Newton data of the same cluster in order to make the connection
to the inner regions, unresolved by Suzaku, and to determine the smearing due
to Suzaku's PSF. Results: The temperature profile of Abell 2204 is determined
from 10 kpc to 1800 kpc, close to an estimate of r200 (the approximation to the
virial radius). The temperature rises steeply from below 4 keV in the very
center up to more than 8 keV in the intermediate range and then decreases again
to about 4 keV at the largest radii. Varying the measured particle background
normalization artificially by +-10 percent does not change the results
significantly. Predictions for outer temperature profiles based on hydrodynamic
simulations show good agreement. In particular, we find the observed
temperature profile to be slightly steeper but consistent with a drop of a
factor of 0.6 from 0.3 r200 to r200, as predicted by simulations. Conclusions:
Temperature measurements up to the virial radius seem feasible with Suzaku,
when a careful analysis of the different background components and the effects
of the PSF is performed. The result obtained here indicates that numerical
simulations capture the intracluster gas physics well in cluster outskirts.Comment: 7 pages; Astronomy and Astrophysics, accepted; additional systematic
