Lighting Intensity

Using experimental data from four electric lighting scenarios at King’s College Chapel in Cambridge, we developed an integrated approach to evaluating the overall impression of concert lighting. First, we performed a group analysis based on the aggregated response from the audience, conductor and musician respondents, followed by an overall analysis accounting for all 624 responses. Ordered logistic regression analysis revealed the absence of statistically significant subjective–objective relationships for perceived visual balance, appropriateness, comfort and the overall impression. There were, however, significant results when the variables were correlated with subjective attributes. This suggests that the perceptual process was bi-level. To gain a more complete understanding of the perceived qualities, it is necessary for an approach to consider not only the intercorrelations between the subjective and objective measures, but also the intracorrelations among the subjective attributes. Further analysis of variance showed that increasing the overall lighting intensity was more likely to lead to a lower level of satisfaction. Nevertheless, providing peripheral and directional lights appeared to be the key to improving the overall impression. This paper confirms that combining detailed and generalised approaches to evaluate subjective responses can yield more meaningful interpretations, enabling relations with measures to be established with greater confidence.

Logistic Regression Modelling

This paper presents experimental approaches for evaluating concert lighting from the viewpoints of audience members and performers in Cambridge King's College Chapel. We develop image zoning and abstraction techniques to quantify and interpret photometric data acquired under four different electric lighting conditions. Assessed by 78 participants, these lighting scenarios are compared across six different viewing positions using a set of structured questionnaires. Ordered logistic regression modelling shows that the ratios and functions describing uniformity, brightness and light patterns are common explanatory variables for predicting perceived visual clarity, visual uniformity, brightness and spatial intimacy. Uniformity-related attributes are observed to be among the strongest variables for all these perceived qualities, except for visual clarity, which is better explained by acuity-related measures. These experimental results confirm the applicability of our approaches, highlighting the importance of combining multiple methods and integrating complex architectural situations into the process of understanding luminous appearance.

AimsThis study aimed to assess the level of satisfaction patients feel towards their experience of attending for psychotherapy, in order to inform local management on the service being offered by the department.BackgroundThis survey was conducted as part of routine service provision analysis by the psychotherapy department. It aimed to assess the level of satisfaction patients feel towards their experience of attending for psychotherapy, in order to inform local management on the service being offered by the department. Ethics committee confirmed this fulfilled “Service evaluation” criterion and the project was registered with the local NHS quality improvement register.MethodPatients who completed an episode of therapy were invited to complete a survey form. This consisted of a Client Satisfaction Questionnaire (CSQ-8) as well as four additional questions pertaining to patient satisfaction. The patient's therapist would inform administration staff of the patient's final appointment; administration staff would then issue the patient with a questionnaire which they were invited to complete and return in their own time. The questionnaires were completed anonymously and no reward was offered for completing the questionnaire. The therapies included group analysis, psychodynamic individual and Cognitive Analytic Therapy.Result2 patients who had completed psychotherapy in 2018-2019 returned a completed questionnaire. The average and range responses were examined.The average response was “4: Excellent” for the overall rating of the service received, and for 5 other questions on the CSQ-8 the average score was the highest possible. The average response was slightly lower on the question about whether the service met their needs “3: Mostly”, and on the question: Has the service you received helped you to deal more effectively with your problems? (3 yes, somewhat). The additional questions highlighted how important the setting and administration role played in the experience of therapy. The questionnaire also included a free text box giving the patient the opportunity to offer any other comments. Many of these included messages of gratitude and remarks on the impact therapy has had on their general wellbeing.ConclusionIn general it is encouraging to see that feedback provided through this survey was extremely positive. This was reflected both in the Likert scale questions and the free text box. Patients are described themselves as very satisfied with their experience within therapy and reflected a positive experience of the holding environment provided by the department as a whole.(NO Funding received)

The Impact

AbstractLocalizing human brain functions is a long-standing goal in systems neuroscience. Towards this goal, neuroimaging studies have traditionally used volume-based smoothing, registered data to volume-based standard spaces, and reported results relative to volume-based parcellations. A novel 360-area surface-based cortical parcellation was recently generated using multimodal data from the Human Connectome Project (HCP), and a volume-based version of this parcellation has frequently been requested for use with traditional volume-based analyses. However, given the major methodological differences between traditional volumetric and HCP-style processing, the utility and interpretability of such an altered parcellation must first be established. By starting from automatically generated individual-subject parcellations and processing them with different methodological approaches, we show that traditional processing steps, especially volume-based smoothing and registration, substantially degrade cortical area localization when compared to surface-based approaches. We also show that surface-based registration using features closely tied to cortical areas, rather than to folding patterns alone, improves the alignment of areas, and that the benefits of high resolution acquisitions are largely unexploited by traditional volume-based methods. Quantitatively, we show that the most common version of the traditional approach has spatial localization that is only 35% as good as the best surface-based method as assessed with two objective measures (peak areal probabilities and ‘captured area fraction’ for maximum probability maps). Finally, we demonstrate that substantial challenges exist when attempting to accurately represent volume-based group analysis results on the surface, which has important implications for the interpretability of studies, both past and future, that use these volume-based methods.Significance StatementMost human brain imaging studies have traditionally used low-resolution images, inaccurate methods of cross-subject alignment, and extensive blurring. Recently, a high-resolution approach with more accurate alignment and minimized blurring was used by the Human Connectome Project to generate a multi-modal map of human cortical areas in hundreds of individuals. Starting from this data, we systematically compared these two approaches, showing that the traditional approach is nearly three times worse than the HCP’s improved approach in two objective measures of spatial localization of cortical areas. Further, we demonstrate considerable challenges in comparing data across the two approaches, and, as a result, argue that there is an urgent need for the field to adopt more accurate methods of data acquisition and analysis.

BackgroundWith greater transparency in health system reporting and increased reliance on patient-centred outcomes, patient satisfaction has become a priority in delivering quality care. We sought to explore the relationship between patient satisfaction and short-term outcomes in patients undergoing general surgical procedures.MethodsSatisfaction surveys were distributed to patients following discharge from the general surgery service at an academic hospital between June 2012 and March 2015. Short-term clinical outcomes were obtained from the American College of Surgeons National Surgical Quality Improvement Program database. Patients rated their level of satisfaction on a 5-point Likert scale, and ordered logistic regression model was used to determine predictors of high patient satisfaction.Results757 patient satisfaction surveys were completed. The mean age of patients surveyed was 52.2 years; 60.0% of patients were female. The majority of patients underwent a laparoscopic procedure (85.9%) and were admitted as inpatients following surgery (72%). 91.5% of patients rated satisfaction of 4–5, and 95.0% said they would recommend the service. The odds of overall satisfaction were lower in patients who had complications (OR: 0.52, 95% CI 0.31 to 0.87) and 30-day readmission (OR: 0.35, 95% CI 0.17 to 0.70). Having elective surgery was associated with higher odds of satisfaction (OR: 1.62, 95% CI 1.07 to 2.47).ConclusionsWe found a significant association between patient satisfaction and both 30-day readmission and the occurrence of postoperative surgical complications. Given this association, further study is warranted to evaluate patient satisfaction as a healthcare quality indicator.

Lighting experiments were performed in a real context populated with dummies and objects. Using the King’s College Chapel in Cambridge as a case study, two field surveys of concert lighting were performed, one with the chapel empty and one with it occupied. In each survey, photometric data were collected under three electric lighting conditions and from six different viewing positions. A comparative analysis indicates that the data gathered from the occupied space represent the luminances more accurately, present a more detailed description of the light distribution, and provide a more extensive set of variables characterising the geometrical details of the visual scene. This study demonstrates the importance of using occupied spaces and considering the presence of occupants in field studies, which could be useful for obtaining a more complete understanding of complex luminous environments.

And Function

The present knowledge of the three-dimensional structure of ribosomes is far too limited to enable a complete understanding of the various roles which ribosomes play in protein biosynthesis. The spatial arrangement of proteins and ribonuclec acids in ribosomes can be analysed in many ways. Determination of binding sites for individual proteins on ribonuclec acid and locations of the mutual positions of proteins on the ribosome using labeling with fluorescent dyes, cross-linking reagents, neutron-diffraction or antibodies against ribosomal proteins seem to be most successful approaches. Structure and function of ribosomes can be correlated be depleting the complete ribosomes of some proteins to the functionally inactive core and by subsequent partial reconstitution in order to regain active ribosomal particles.

Recent progress in the application of scanning tunneling microscopy (STM) and tunneling spectroscopy (STS) to oxide surfaces has allowed issues of image formation mechanism and spatial resolution limitations to be addressed. As the STM analyses of oxide surfaces continues, it is becoming clear that the geometric and electronic structures of these surfaces are intrinsically complex. Since STM requires conductivity, the oxides in question are transition metal oxides that accommodate aliovalent dopants or nonstoichiometry to produce mobile carriers. To date, considerable effort has been directed toward probing the structures and reactivities of ZnO polar and nonpolar surfaces, TiO2 (110) and (001) surfaces and the SrTiO3 (001) surface, with a view towards integrating these results with the vast amount of previous surface analysis (LEED and photoemission) to build a more complete understanding of these surfaces. However, the spatial localization of the STM/STS provides a level of detail that leads to conclusions somewhat different from those made earlier.
