Choi, Young-Seon. "The physical environment and patient safety: an investigation of physical environmental factors associated with patient falls." Diss., Georgia Institute of Technology, 2011. http://hdl.handle.net/1853/45974.
Testo completoAbstract (sommario):
Patient falls are the most commonly reported "adverse events" in hospitals, according to studies conducted in the U.S. and elsewhere. The rate of falls is not high (2.3 to 7 falls per 1,000 patient days), but about a third of falls result in injuries or even death, and these preventable events drive up the cost of healthcare and, clearly, are harmful outcomes for the patients involved. This study of a private hospital, Dublin Methodist Hospital, in Dublin, Ohio analyzes data about patient falls and the facility's floor plans and design features and makes direct connections between hospital design and patient falls. This particular hospital, which was relatively recently constructed, offered particular advantages in investigating unit-layout-related environmental factors because of the very uniform configuration of its rooms, which greatly narrowed down the variables under study.
This thesis investigated data about patients who had suffered falls as well as patients with similar characteristics (e.g., age, gender, and diagnosis) who did not suffer falls. This case-control study design helps limit differences between patients. Then patient data was correlated to the location of the fall and environmental characteristics of the locations, analyzed in terms of their layout and floor plan. A key part of this analysis was the development of tools to measure the visibility of the patient's head and body to nurses, the relative accessibility of the patient, the distance from the patient's room to the medication area, and the location of the bathroom in patient rooms (many falls apparently occur during travel to and from these areas).
From the analysis of all this data there emerged a snapshot of the specific rooms in the hospital being analyzed where there was an elevated risk of a patient falling. While this finding is useful for the administrators of that particular facility, the study also developed a number of generally applicable conclusions. The most striking conclusion was that, for a number of reasons, patients whose heads were not visible from caregivers working from their seats in nurses' stations and/or from corridors had a higher risk of falling, in part because staff were unable to intervene in situations where a fall appeared likely to occur. This was also the case with accessibility; patients less accessible within a unit had a higher risk of falling. The implications for hospital design are clear: design inpatient floors to maximize a visible access to patients (especially their heads) from seats in nurses' stations and corridors.

Joy, Cody. "Meeting point : The physical and emotional environment." Thesis, Federation University Australia, 2015. http://researchonline.federation.edu.au/vital/access/HandleResolver/1959.17/99924.
Testo completoAbstract (sommario):
This investigation uses a phenomenological framework to explore how an engagement with artistic process might create a meeting point through which to consider the internal and external environments. As a practice-led research project, it is the identification and exploration of artistic process that has led and revealed the theoretical issues to be explored alongside the creation of studio work. The shifting, interwoven oscillation between analytical and intuitive components that occurs in both conceptual underpinnings and the central processes of making, are recognised as being interdependent and mutually beneficial. This reflects both the nature of creative practice and artistic process, that is influential in both the realisation and progression of the theoretical and studio based outcomes. Significantly mark-making is established as a way of co-incidentally entering and extending the intuitive state while engaged in artistic activity. Those engaged with artistic practice are well placed to move between and across boundaries, absorbing and combining knowledge. Individual growth when shared, contributes back to the wider network of knowledge that feeds realisation and development of insight, both within the field of visual art and in other disciplines. The resulting body of work reveals the intuitive artistic development which is realised through a commitment to, and engagement with, individual artistic process. This investigation strengthens acceptance of self in its perfect state of imperfection, ultimately reflected in the wider process of creation going on both within and around all of us. The processes of creating art and creating self are therefore linked through engagement with materials and an awareness of the place where all things meet, the work. Realisation of the significance of art practice and the subsequently heightened focus on discovery, change and adaptability, aids physical and emotional recovery following adversity and raises areas of potential research for the future.<br>Bachelor of Visual Arts (Honours)

Testo completoAbstract (sommario):
The problem addressed in this thesis is that a considerable proportion of students around the world attend school in inadequate facilities, which is detrimental for the students’ learning outcome. The overall objective in this thesis is to develop a methodology, with a novel approach to involve teachers, to generate a valuable basis for decisions regarding design and improvement of physical school environment, based on the expressed needs for a specific school, municipality, or district as well as evidence from existing research. Three studies have been conducted to fulfil the objective: (1) a systematic literature review and development of a theoretical model for analysing the role of the physical environment in schools; (2) semi structured interviews with teachers to get their conceptions of the physical school environment; (3) a stated preference study with experimental design as an online survey. Wordings from the transcripts from the interview study were used when designing the survey form. The aim of the stated preference study was to examine the usability of the method when applied in this new context of physical school environment. The result is the methodology with a mixed method chain where the first step involves a broad investigation of the specific circumstances and conceptions for the specific school, municipality, or district. The second step is to use the developed theoretical model and results from the literature study to analyse the results from the first step and transform them in to a format that fits the design of a stated preference study. The final step is a refined version of the procedure of the performed stated preference study.

Jacucci, Carlo. "Media literacy in responsive physical environments." Thesis, University of Edinburgh, 2008. http://hdl.handle.net/1842/4373.
Testo completoAbstract (sommario):
This thesis addressed the production of media literacy practices in physical environments. It reflects a specific trajectory through a design space. The work is founded on four studies including design sessions and expositions in primary schools and in an art museum. The focus is on how to devise practices and make sense of media literacy tasks. the thesis addresses research problems of interaction design and media studies by:(a)configuring interactive tangibles and audiovisual media, to give different perspectives on media literacy within the same physical environment; (b) developing a set of practices which are attuned to how participants collaborate when accessing and producing media texts; (c) developing the design method by employing practical knowledge from theatre practices. The thesis tackles some specific design problems. One is that the qualities of the practices and qualities of the tools need to be addressed at the same time. Also, aesthetic and technical aspects often are indistinct. The thesis seeks help in some specific traditions in the performing arts. Some terms such as 'participatory theatre' and 'masked performance' are redefined in order to address both aspects of practices and tools. Terms such as 'gendre', 'framing', 'packaging', 'authoring', 'deconstruction', 'media agenda setting' are also redefined frm literature on media studies, through the production and study of collective activities. The thesis aims to contribute to the integration of findings in interaction desugb abd nedua stydues by (1) applying advances from interaction design for the support of new media literact practice in the physical environment; (2) applying the perspectives on media literacy which emerge from these integrations in order to contribute to current reesearch on interaction design. The thesis applies practices from the performing arts in order to enable a participatory design of physical environments for media literacy. The focus is on the role played by audience groups when they adopt media contents and artifacts.

Sawyer, A. D. M. "Role of the social and physical neighbourhood environment in physical activity in deprived communities." Thesis, University College London (University of London), 2018. http://discovery.ucl.ac.uk/10044539/.
Testo completoAbstract (sommario):
Physical activity is associated with numerous physical and psychosocial health benefits, yet population levels in the United Kingdom remain low, particularly in lower socioeconomic groups. Socioecological models posit that social and physical environments have independent and interactive influences on physical activity. Although a growing body of literature has examined the independent effect of aspects of the social and physical environment, interactive effects are rarely assessed. In addition, there is limited research specifically examining independent or interactive environmental influences in populations vulnerable to lower levels of physical activity, such as those living in neighbourhoods with high levels of deprivation. This thesis examines the association between quality of the neighbourhood physical environment (aesthetics, maintenance, physical disorder) and social environment (cohesion, safety, social interaction, support, trust, empowerment) on physical activity in adults living in income-deprived communities, using Glasgow as a case study. Cross-sectional analyses, conducted using a socioecological approach, suggested independent and interactive effects of objectively measured physical environmental factors and perceived social environmental factors on neighbourhood-based walking and moderate physical activity. Longitudinal analyses found little evidence that changes in environmental measures predict change in self-reported walking. However, qualitative analyses provided insight into potential causal pathways through a system of interacting environmental factors. Together, findings from this thesis suggest a role for the quality of the neighbourhood physical and social environment on activity, providing some evidence of interactive effects of the neighbourhood social and physical environment. Further research is needed to elucidate causal relationships between the quality of the neighbourhood environment and physical activity. Findings call for a complex systems approach to understanding contextual environmental effects on physical activity in deprived communities.

Wood, C. "Exercise environment and physical activity in children and adolescents." Thesis, University of Essex, 2012. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.574469.
Testo completoAbstract (sommario):
The majority of UK children and adolescents are not meeting physical activity (PA) recommendations, despite the benefits for physical and psychological health (PH). Natural environments facilitate PA and in adults performing PA whilst exposed to nature ('green exercise') results in additional benefits for PH. However, the effects of exercise environment have not been extensively studied in children and adolescents. The primary aim of this study was to examine the effect of exercise environment on the time spent in moderate to vigorous PA (MVPA) in children and adolescents. The secondary aim was to determine whether green exercise provides additional benefits for PH. Due to variation in PA patterns and opportunities for contact with nature, children and adolescents were examined separately. For children, accelerometers (ACCs) determined whether school playtime (SP) on the field and participation in nature- based interventions lead to greater MVP A than play on the playground and participation in playground-based interventions. A child version of Rosenberg's Self- esteem Scale (RSES), developed and reported in this thesis, examined the effect of the environmental conditions on self-esteem (SE). In adolescents, heart rate (HR) examined and compared the effect of indoor and outdoor environments on MVP A, whilst ACCs assessed the influence of acute exposure to urban and rural environments on P A. RSES and the adolescent profile of mood states (POMS-A) questionnaire compared the effect of the environments on SE and mood. In both children and adolescents, results indicated that natural environments led to higher levels of MVP A. No additional benefits for PH were provided by performing PA in natural environments. Unlike in adults, the current generation of youth do not seem to be connected to nature in a way that allows it to influence their PH. Nature can be used to promote PA in children and adolescents and should thus be incorporated into everyday routines.

Griew, Pippa. "The school environment and children’s school-time physical activity." Thesis, University of Bristol, 2012. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.573400.
Testo completoAbstract (sommario):
Background & study aims: Physical activity during childhood is associated with health benefits across the life course. The school setting is important for children's physical activity, yet we do not know whether the school a child attends is related to their sedentary and moderate-to-vigorous physical activity. This study aims to assess: (1) patterns in sedentary-time and MVPA during school-time, (2) the extent to which these vary between schools and, (3) which characteristics of the school physical and social environment are related to children's sedentary-time and MVPA at school. Methods: Participants were 707 children (boys n=340) aged 10-11 years old from 17 schools in Bristol, UK recruited between September 2006 - July 2008 as part of the PEACH project (Personal and Environmental Associations with Children's Health). The percentage of time spent sedentary «100cpm) and in MVPA (~2000cpm) during lesson and free-time at school were assessed for boys and girls with Actigraph accelerometers. Perceptions of peer, teacher and school support for physical activity were assessed via a computerised questionnaire, a school grounds survey was conducted to assess the school physical environment and weather variables were recorded at each school. Between school differences in children's physical activity and associations with school environment characteristics were investigated using multilevel analysis (MLwin 2.22). Results: Children spent an average of 8% (32 (SO 14) minutes) of school time in MVPA and 65% (250 (SO 31) minutes) sedentary. Boys were significantly more active and less sedentary than girls over the total school day. These gender differences were greatest during free-time with boys achieving 43% (8 minutes) more MVPA and 27% (11 minutes) less time sedentary. Boys were least sedentary at schools with longer free-time duration (~-0.44, (SE: 0.12)), high peer support (~-3.52, (SE: 1.11)) and the least rainfall (~0.67, (SE: 0.24)) and achieved most MVPA at schools with longer free-time duration (~0.105, (SE: 0.077)), larger campus size (~0.007 (SE: 0.004)), high peer support (~2.22, (SE: 1.06)), the least rainfall (~-0.926, (SE: 0.212)) and colder temperatures (~-0.408, (SE: 0.143)). Girls were least sedentary at schools with longer lesson-time duration (~-0.16, (SE: 0.06)), high quality playground markings (~-3.06, (SE: 1.00)), high school support (~- 1.83, (SE: 0.76)), the least rainfall (~0.31, (SE: 0.12)) and highest temperatures (~-0.36, (SE: 0.12)). Girls achieved the most MVPA at school with longer lesson-time duration (~0.06 (SE: 0.03)), larger campus size (~ 0.04, (SE: 0.02)), less playground equipment (~- 0.23, (SE: 0.10)) and highest temperatures (~0.16, (SE: 0.05)). Conclusion: Opportunities to increase MVPA and reduce time spent sedentary exist within school-time, particularly for girls. Significant differences in sedentary-time and MVPA occur between schools that can largely be explained by characteristics of the school environment. Environmental modifications may, therefore, provide effective intervention. However, intervention strategies will need to consider the differing school environment characteristics associated with physical activity for boys and girls.

Ryan, Grant James. "Dynamic physical analysis of long term economy-environment options." Thesis, University of Canterbury. Chemical Engineering, 1995. http://hdl.handle.net/10092/4375.
Testo completoAbstract (sommario):
This thesis presents a methodology for structural economy-environment simulation modelling (SEESM), and a demonstration of its application to New Zealand. The problem analysed in this thesis is the identification of long term physical limits on economic growth; in particular, a joint physical analysis of economic growth, technological development and resource scarcity.
It is important to analyse physical causes of technological change as this is an area the conventional economic growth models ignore. A growth model has been developed that includes physical influences on technological development while still recognising that investment accelerates the learning process. Although no clear conclusion can be made about the link between technological progress (learning) and energy analysis this is a promising area for further investigation.
The dynamic simulation modelling approach developed by Malcolm Slesser and others (ECCO) is reviewed, and a number of shortcomings identified. Three significant modifications are presented. First, growth in the new models is based on the neoclassical idea that technology is the main driver of economic growth rather than on classical growth theory which emphasis savings as the main determinant of growth. Secondly, the numeraire used in the models is a dimensionless index of volume so the model does not assume an energy theory of value. Finally, the model is based on a full set of input-output data which enables a more accurate analysis of flows between sectors in the economy. Thus, it has the advantage of the detailed structural information found from input-output analysis combined with the flexibility of simulation models. The resulting model is ideal for investigating the complex dynamic phenomenon of an evolving physical economy.
The purpose of this model is not to predict future economic growth but to highlight the physical assumptions required for any particular scenario. Once these physical assumptions have been identified, they are open to scrutiny and can easily be changed to test their importance.
A dynamic input-output model has been applied to the New Zealand economy and several different scenarios have been tested. The simulations include changing the overall growth rate of the economy, changing relative growth rates of different sectors, changing energy efficiencies, and introducing renewable energy technologies on a large scale. These simulations show that in some cases there are significant indirect physical flows that may not have otherwise been accounted for.

Cin, Mustafa. "The influence of direct experience of the physical environment on concept learning in physical geography." Thesis, Durham University, 1999. http://etheses.dur.ac.uk/4480/.
Testo completoAbstract (sommario):
This investigation examines the relationship between children's direct experience of the physical environment and their conceptual understanding of it. In order to determine the extent of the influence of the physical environment on understanding, two groups of children living in different geographical environments were selected and their perceptions and understanding of the selected physical features related to their immediate surroundings were compared. The children's ideas about the features selected were examined using a number of research techniques. The results tended to support the central assertion of the study that the physical environment has an influence on children's conceptual understanding. The data also showed that the children held a number of alternative conceptions about their near and far environment prior to the experience of formal instruction. The relevance of these conclusions for geographical education is presented. Suggestions are made to improve the quality of teaching and learning in physical geography. Fieldwork, hardware models, simulation activities and Information and Communication Technology (ICT) are suggested for use as teaching approaches. The significance of the conclusions in the context of Turkish geographical education are also considered.

Nyabando, Tsitsi. "Second-Grade Students’ Perceptions of Their Classrooms’ Physical Learning Environment." Digital Commons @ East Tennessee State University, 2019. https://dc.etsu.edu/etd/3660.
Testo completoAbstract (sommario):
Guided by the constructivist framework, the focus of the investigation was on second-grade students and their perceptions of their classrooms’ physical learning environment.
A qualitative multiple case study approach was employed, and data were collected through interviews, participant-generated photographs, and observations. Participants in the study were 16 second-grade students in four classrooms in three school districts in Northeast Tennessee. A physical learning environment tool, Assessing the Pillars of the Physical Environment for Academic Learning (APPEAL), developed by Evanshen and Faulk (2019) was used to select classrooms to take part in the study. The tool focuses on dimensions that help observers evaluate the quality of the primary classroom physical learning environment on a continuum of traditional to constructivist elements.
Findings revealed that second-grade students are aware of, and are affected by, their classrooms’ physical learning environment. Generally, participants believed that classroom physical learning environments that were best for them were meaningful, offered easy access to resources and materials, and provided opportunities for active learning and social engagement. Both physical and emotional comfort were important to participants.
There were more similarities than differences between the perceptions shared by participants in the classrooms that scored highest on the APPEAL (more constructivist or student-centered) and the classrooms that scored lowest (more traditional or teacher-centered) on the scale. Some of the differences that emerged were that all the students who were in the teacher-centered classrooms identified features connected to computers as something they liked whereas most of the students in the learner-centered classrooms did not. Students in the learner-centered classrooms were more articulate in talking about how displays helped them to learn, and students in the teacher- centered classroom communicated the need to change displays.
Additionally, the findings suggested that young children’s perceptions about the environment can be influenced by their experiences or contexts and their individual differences. The findings encourage teachers of young children to think about their students as actively affected by their environment and challenge them to design classroom physical learning environments that support the diverse needs of students within these spaces.

Testo completoAbstract (sommario):
Nowadays, the industry is witnessing the revolution called Industry 4.0. Many manufac‐turing industries are jumping to this new technology, Industrial Internet of Things (IIoT) to improve performance and efficiency in their processes. However, some industries do not want to jump to this new era due to big changes. That is where this project comes in, being its aim to create a CPS from an existing process, working with IIoT. In order to accomplish this, Mosquitto, CoDeSys, ThingSpeak and MQTT Dashboard, as well as Simumatik are going to be used to create a communication system based on three layers. The development of the project is based in adapting sensors and actuators to IIoT in Simumatik, configure all the connections between services and programming inside CoDeSys and Thing Speak, as well as creating an MQTT Dashboard inside a mobile application. Once the project has been developed, some conclusions could be taken out, such as easy scalability and cheaper implementation, con‐suming less wire and less PLC modules, although it is needed cutting edge technologies tools to process all data and find ways to optimize a process.

Testo completoAbstract (sommario):
The geological history of Greece has produced a generally highly indented coastline, with many islands lying in the neighbouring seas; some coastal areas, however, feature long stretches of high cliffs, or of sandy shallows. Marine erosion has further developed coastal indentation, and has produced many typical erosion features. Sea currents around Greece, which are governed by the inflows of water into the Mediterranean at Gibraltar and at the Hellespont, are regular, owing to the weakness of Mediterranean tides, and are strongest in straits and off major headlands. The Greek climate is also regular, falling into two distinct seasons; summer features strong, regular, northerly winds, clear skies, and great heat and drought, while winter is typified by eastwards-moving depressions which bring strong, stormy, and unpredictable winds, as well as cloud and rain, especially in coastal areas, where winds blowing off the sea meet land barriers (ch.1). Such topographical, oceanographic, and meteorological conditions meant that headlands and straits were areas of particular navigational difficulty. Yet these same conditions entailed a ready availability of shelter, in natural harbours, in river mouths, and behind promontories and islands. Areas composed of unbroken cliffs, or of flat, featureless shallows, on the other hand, afforded no such shelter (ch. 2). The physical environment thus also strongly influenced the routes taken by mariners, especially with regard to the degree to which ships 'hugged the coast'. Headlands and islands were the principal points at which major changes of direction were made, and, along with some other prominent topographical features, took on the role of milestones and landmarks, for which they were well suited. Incidental structures such as towers, tombs, and temples, took on similar roles, and were particularly important in inshore navigation. Where, due to distance or darkness, terrestrial landmarks were not visible, sailors' knowledge of other aspects of the physical environment was of paramount importance for safe and successful navigation (ch. 3).

Adams, Curtis B. "Optimizing the Physical and Nutritional Environment of Unleached Root-Zones." DigitalCommons@USU, 2010. https://digitalcommons.usu.edu/etd/565.
Testo completoAbstract (sommario):
Unleached root-zones represent an environmental ideal by eliminating wasteful leaching of nutrients and water. NASA grows plants in space in unleached root-zones, incorporating polymer-coated fertilizer (PCF) into a ceramic media (Turface or Profile). However, lack of growth productivity in space has led to the need for research to improve the nutritional and physical environment of the root-zone, which is the objective of this research. PCF types are diverse in release characteristics and the effects of temperature and substrate water content have not been well characterized. In spite of widespread use, studies on chemical properties and applied studies to verify soil physical models of ceramic media have been limited. We quantified the release rate of three widely-used types of PCF (Polyon, Nutricote, and Osmocote) in water and in sand over a wide range of temperature (5, 15, 20, 30, and 40ºC). Results indicated that substrate water content had a minimal effect on release rates. Nutricote fertilizers were the most consistent in releasing individual nutrients with temperature and over time. Polyon fertilizers had the slowest release rates relative to the manufacturer's specifications, but a relatively linear response to temperature. Osmocote fertilizers rapidly released nutrients at all temperatures. For more efficient PCF use, we present a comprehensive model that couples models to predict plant growth and PCF nutrient release rates. This model is based on phosphorus release, the nutrient found to be limiting to PCF-fertilized plants. The efficacy of the model to accurately predict PCF application rates was verified with a growth trial. In ceramic media, relative media-sorbed nutrient concentrations were highly variable from bag to bag. Excesses of manganese, boron, magnesium, and sulfur in the media induced nutrient imbalances in plant tissues. Rinsing and soaking procedures on the media helped mitigate these nutrient imbalances. Ceramic media also interacted with added fertilizer ions. Copper, phosphorus, and zinc ions were largely removed from solution by these interactions. We also used plants to extract water from root-zones of ceramic media to characterize plant-available water and water supply dynamics. The results suggest that soil physical models may be used to predict plant-available water in ceramic media.

Testo completoAbstract (sommario):
Despite the increasing number of individuals taking computer-based tests, little is known about how examinees perceive computer-based testing environments and the extent to which these testing environments are perceived to affect test performance. The purpose of the present study was to assess the testing environment as perceived by individuals taking the National Physical Therapy Examination (NPTE), a high-stakes licensure examination. Perceptions of the testing environments were assessed using an examinee self-report questionnaire. The questionnaire included items that measured individuals’ preference and perception of specific characteristics of the environment, along with demographic information and one open-ended item. Questionnaires were distributed by email to the 210 accredited physical therapy programs at the time, encouraging programs to forward the instrument by email to the most recent class of physical therapy graduates. Two hundred and sixteen respondents completed the study, representing 101 testing centers in 31 states.
Data from these 216 examinees were used to answer four research questions. The first research question focused on the examinees’ environmental preferences for the NPTE testing environment and the relation between these preferences and examinees’ background characteristics (e.g., sex, program GPA, age, online experience, online testing experience, comfort level with online testing, and preferred testing time). A clear preference toward one end of the scale was observed for preferring a quiet room and a desktop area that had a great deal of adjustability. Examinees’ preferences and their demographic characteristics were not strongly related with the seven demographic variables accounting for < 7% of the variability in examinees’ environmental preferences.
The second research question used the data from multiple examinees nested within the same testing center to examine the within- and between-center variability in examinees’ perceptions of the testing environment and their satisfaction with the environment. Results indicated that the majority of the variance in these variables was within testing centers with average between-center variability equal to .032 for the perception ratings and .078 for the satisfaction ratings. Research questions (RQ) three and four explored whether examinees’ background characteristics (RQ 3) and center characteristics (RQ 4) were significantly related to the 12 environmental perception ratings, 12 satisfaction ratings, and two items representing examinees’ perceptions of the effect of the testing environment on their performance and the likelihood they would choose the same center again. In terms of examinee characteristics, age, online testing experience, and comfort with online testing were the most consistent predictors of the various examinee ratings. The most consistent predictors for the satisfaction ratings were examinees’ online test comfort, online test experience, and age. For center characteristics, the newness of the center and the room density of the center were the most consistent predictors of examinee ratings. For satisfaction ratings, the most consistent predictor was the newness of the center. Center newness was significantly related to the outcome variables related to the size, lighting and sound of the center which may reflect changes in building standards and materials.
The results of the study suggest the need for further exploration of the environmental and human factors that may impact individuals taking high stakes examinations in testing centers. Although there may not be an effect on all examinees, there may be subsets of individuals who are more sensitive to the effects of the testing environment on performance. Further exploration of the uniformity of testing environments is also needed to minimize error and maximize potential threats to test security.

Testo completoAbstract (sommario):
Background: The impact of neighbourhood physical environments on physical activity and health is widely acknowledged, with much research conducted to identify key factors. Results have been mixed, partly due to inconsistencies in how neighbourhoods are defined. This thesis examines relationships of physical environments with physical activity, and with depression, exploring influence of neighbourhood operationalisation. Method: Physical activity and depression outcomes were derived from a sample drawn from the seventh wave of the Whitehall II study conducted in 2004/5, and depression outcomes were also taken from the 2008 Health Survey for England. Neighbourhoods were operationalised at three levels of administrative geography and as residential postcode-centred GIS software-computed zones. Four main exposure variables were specified: a greenspace measure was constructed from the Generalised Land Use Database; an objective measure of environmental quality was derived from metadata of the Multiple Environmental Deprivation Index, and a subjective one from the 2008 Place Survey; and a walkability measure was constructed using GIS, drawing on several geographical databases. Multivariate logistic regression was used to measure statistical associations between exposures and outcomes, with adjustment for individual-level sociodemographic factors and area-level deprivation, and multilevel modelling was performed to estimate the contribution of neighbourhood characteristics relative to those of individuals to variation in outcomes. Results: Neighbourhood physical environments accounted for a small proportion of variation in all outcomes. Nevertheless, significant associations were found between all exposure variables and physical activity, independently of individual-level sociodemographic factors and area-level deprivation, the direction dependent on outcome specification. Only objectively measured environmental quality was significantly and independently with depression, with lower quality giving higher odds of this outcome. Strengths of associations were not substantively affected by neighbourhood operationalisation. Conclusion: This thesis increases understanding of physical environment attributes relevant to physical activity and depression in a European context and how neighbourhoods in which they are measured may best be defined.

Physical inactivity and disconnection from natural environments threatens human health. However, research has demonstrated that natural environments potentially support health-enhancing physical activity which could confer greater physical and mental health benefits than physical activity in other types of environment. This thesis approached the study of physical activity in natural environments through three related pieces of research. Firstly, an experimental study was carried out to explore how the presence of litter in beach environments affected psychophysiological responses to exercise. Responses to exercise did not differ in littered and clean conditions but there was evidence that order effects influenced findings. Visual attention to the two scenes differed, but did not mediate differences in psychophysiological responses. Secondly, analysis of a national dataset was undertaken to explore the form and quantity of physical activity conducted within natural environments in England. A series of linear regressions revealed that higher-intensity physical activities occurred in countryside environments, but more total energy expenditure occurred in coastal environments. Thirdly, a quantitative content analysis of brochures which promote recreational walking in natural environments was conducted which investigated their use of persuasive behavioural messages. These brochures omitted behavioural techniques which may be effective at motivating inactive individuals to walk. Extending this, an online survey tested whether improving brochure content heightened intentions to walk in natural environments. By designing content based on the theory of planned behaviour, the intentions of inactive individuals to undertake walking in natural environments were increased. The findings from this thesis demonstrate that the protection of natural environments is vital for preserving and promoting active recreation and could contribute to population-level increases in physical activity with theory-based promotion in the future.

Testo completoAbstract (sommario):
Physical activity determinant studies now often include both environmental and socio-cognitive factors but few of them acknowledge and explore the mechanisms underlying relevant environmental influences. This thesis addressed the gap in current knowledge by exploring pathways linking the environment and physical activity in children beyond the limits of models such as the Theory of Planned Behaviour (Ajzen, 1991), by examining the more complex automatic and habitual mechanisms underlying this behaviour. First, a TPB questionnaire was developed to assess physical activity cognitions in children (study 1). This was followed by a psychometric evaluation of the Physical Activity Questionnaire for Older Children (PAQ-C) (Crocker, Bailey, Faulkner, Kowlaski & McGrath, 1997) (study 2). Building on the first two studies, study 3 utilized these measures to delineate the mechanisms linking the environment and physical activity in children. Results showed that nearly 43% of the association between convenient facilities and physical activity intentions could be explained by subjective norms (16.7%) and habit strength (26.2%), while 15% of the association between convenient facilities and physical activity could be explained by habit strength alone. Study 3 provided the impetus for the development, implementation and evaluation of a theory based cluster randomised control trail to increase physical activity in children (study 4). Results revealed a significant increase in PAQ-C scores for those in the intervention group, however perceived access to convenient facilities and habit strength did not significantly increase as a result of the intervention and did not mediate the intervention effect. There was however some evidence that the intervention increased intention – behaviour consistency. The results demonstrate the importance of concepts such as environmental accessibility and habit strength in the prediction of children's physical activity, however further research is required to elucidate the role of these factors in producing intervention effects.

The aims of this thesis were: 1) to identify resources that may be important in the housing of laboratory rabbits (from a survey of the pharmaceutical industry, visits to laboratories and consultation with the industry) and 2) to test the motivation of rabbits for the identified resources. From the survey and behavioural observations of rabbits in different housing systems, it was decided that further investigations would focus on female New Zealand White rabbits and the importance of social contact and platforms within cages. The importance of these resources for rabbits was assessed using both short and long-term motivational tests and observations in laboratory cages. An initial experiment to develop motivational tests identified that weighted push-doors were perceived as costly, but moving through a water bath and approaching an air-stream were not. Short-term motivational tests were set up to give singly and pair caged rabbits the opportunity to push through a weighted push-door to gain a short period of visual and minimal tactile contact with another rabbit. The rabbits pushed through heavier weights to gain social contact than for no reward. Olfactory cues were found to be important, as several rabbits did not push through even the unweighted push-door when the other rabbit was removed. Also, socially housed rabbits pushed through heavier weights for social contact when they were housed out of olfactory contact with their cage-mate. A closed economy consumer demand experiment using weighted push-doors was set-up to test longer term motivation for resources. Two different economic measures (maximum price paid and total expenditure) were used to rank the importance of food, visual and minimal tactile contact, a platform and an empty cage. Both measures showed food and social contact to be of equal and most importance, whilst the importance of the platform varied with the economic measure used.

<p> The primary purpose of this quantitative study was to examine if simulation training correlated with the decision-making abilities of firefighters from two departments (one in a mountain state and one in a southwest state). The other purposes were to determine if firefighter demographics were correlated with the completion of the simulation training and/or predicted decision-making abilities. The independent variables of this study were the completion simulation-training program and selected firefighter demographics with the naturalistic decision-making abilities of these firefighters as the dependent variable. Using purposive sampling, the participants selected were members of the two sample fire departments. The survey contained three categories: demographic information, simulation-based training program overview, and simulation-training assessment. The study produced some statistically significant findings which provided empirical evidence regarding the effective use of simulation training to the decision-making ability of firefighters. It also addresses the void in the existing knowledge base on the effectiveness in using simulation training on the decision-making ability on the fire ground, which firefighters need particularly.</p>

Testo completoAbstract (sommario):
<p>The purpose of writing Pastoral Health and Burnout: Spiritual Maturity, Emotional Health, and Physical Environment is to integrate biblical and psychological insights to test three suspected factors of burnout among senior pastors. This is accomplished through the creation of the Ream Pastoral Health Scale (RPHS), a 60-question Likert scale survey designed to assess the health of a senior pastor according to spiritual maturity, emotional health, and physical environment. The RPHS was validated using the Maslach Burnout Inventory (MBI). The MBI is a nationally recognized assessment tool for measuring burnout in the secular word. Eighty-three Christian and Missionary Alliance senior pastors from various districts in the United States were surveyed with the Ream Pastoral Health Scale and the Maslach Burnout Inventory. Strong correlations were found between the RPHS and the MBI.

Testo completoAbstract (sommario):
This study examined the effects of entrepreneurship level and legal regulatory environment on environmental scanning in one component of the health services industry, private practice physical therapy. Two aspects of scanning served as dependent variables: (1) extent to which firms scrutinized six environmental sectors (competitor, customer, technological, regulatory, economic, social-political) and (2) frequency of information source use (human vs. written). Availability of information was a covariate for frequency of source use. Three levels of entrepreneurship were determined by scores on the Covin and Slevin (1986) entrepreneurship scale. Firms were placed in one of three legal regulatory categories according to the state in which the firm delivered services. A structured questionnaire was sent to 450 randomly selected members of the American Physical Therapy Association's Private Practice Section. Respondents were major decision makers, e.g., owners, chief executive officers. The sample was stratified according to three types of regulatory environment. A response rate of 75% was achieved (n = 318) with equal representation from each stratum. All questionnaire subscales exhibited high internal reliability and validity. The study used a 3x3 factorial design to analyze the data. Two multivariate analyses were conducted, one for each dependent variable set. Results indicated that "high" entrepreneurial level firms scanned the technological, competitor and customer environmental sectors to a significantly greater degree than "middle" or "low" level groups, regardless of type of legal regulatory environment. Also, "high" level firms were found to use human sources to a significantly greater degree than did lower level groups. Empirical evidence supporting Miles and Snow's (1978) proposition that "high" level entrepreneurial firms (prospectors) monitor a wider range of environmental conditions when compared to "low" level (defender) firms was presented. The results also confirmed that market and technological environments were scanned most often. Finally, the results added to the construct validity of the Covin and Slevin entrepreneurship scale and provided evidence of its generalizability to small businesses.

Testo completoAbstract (sommario):
Many dangerous or tragic events such as airplane crashes and medical errors are often the result of human errors, and these errors are often the result of a professional worker being interrupted during a critical task. Although their impact can be serious, the ways that interruptions are affected by the physical environment have rarely been examined in the study of architecture. Therefore, this thesis investigates how the physical environment helps manage the interruptions by observing the process of medication administration by nurses in hospital units. Nurse shadowing observation data showed that the level of visibility of work areas in and around nurse stations significantly contributed to the number of interruptions initiated by others. Therefore, this thesis concludes that the physical environment affects interruption events and discusses the design implications of observation-based findings and the potential impact of the physical environment on major clinical errors. As for future directions for investigation, this thesis suggests that interruptions become a more prominent subject for consideration in architecture, and the physical environment as a subject for analyzing interruption and performance in human factors and health care.

Testo completoAbstract (sommario):
The development of computerised single-space feeding systems, currently used by most breeding companies in their selection programmes, has made it possible to automatically monitor the feeding pattern of individual pigs whilst keeping the animals in a social environment. This thesis examines in detail the feeding pattern of growing pigs and investigates how different components of the social and physical environment affect the feeding behaviour and production performance of the animals. Four experiments were carried out studying the effects of the following factors: Group size, feeder design, trough space, and individual housing. Decreasing the accessibility of the food, either indirectly by increasing pig:trough ratio or directly by fitting an enclosed race in front of the trough, modifies the feeding behaviour of the animals in the direction of fewer, but longer visits to the trough. Increasing the social competition, either directly by increasing the group size or indirectly by offering low levels of protection from other pigs whilst feeding, increases the rate of eating. All pigs succeeded in adapting to the constraint placed on their feeding behaviour and adjusted to the lack of feeding space, as there were no significant effects of social and physical environment on production performance. No correlations were found between social behaviour (aggression level and rank) and any of the feeding behaviour and production variables. A change in the social environment from group to individual housing resulted in only a small increase in feeder visits, regardless of the feeding pattern displayed by the pig whilst group housed. However, this had significant effects on the daily feed intake of those animals with few, long visits, and suggests that these pigs were disadvantaged in terms of daily feed intake rather than number of feeder visits when group housed. The general discussion considers various criteria used in the literature to define 'a meal', briefly discusses the validity of such classifications of visits to the trough, and elaborates on the relationship between food accessibility and feeding pattern. The effects on feeding rate are placed in the context of competition and preferred rate of eating. A large number of additional environmental factors and their influence on feeding behaviour is reviewed.
