Contextually Learnt Detection of Unusual Motion-Based Behaviour in Crowded Public Spaces

In this paper we are interested in analyzing behaviour in crowded publicplaces at the level of holistic motion. Our aim is to learn, without user input, strong scene priors or labelled data, the scope of ‘‘normal behaviour’’ for a particular scene and thus alert to novelty in unseen footage. The first contribution is a low-level motion model based on what we term tracklet primitives, which are scenespecific elementary motions. We propose a clustering-based algorithm for tracklet estimation from local approximations to tracks of appearance features. This is followed by two methods for motion novelty inference from tracklet primitives: (a) an approach based on a non-hierarchial ensemble of Markov chains as a means of capturing behavioural characteristics at different scales, and (b) a more flexible alternative which exhibits a higher generalizing power by accounting for constraints introduced by intentionality and goal-oriented planning of human motion in a particular scene. Evaluated on a 2 h long video of a busy city marketplace, both algorithms are shown to be successful at inferring unusual behaviour, the latter model achieving better performance for novelties at a larger spatial scale.

Form versus function : a study into interactive learning process affecting the implementation of sustainability in commercial buildings

Owners and tenants of sustainable buildings are now realising the sustainable building that they own or occupy and also how they use the building have a significant impact on their work practices. These stakeholders are demanding sustainability outcomes such as improved occupant health and performance, lower energy and material consumption use as well as encouraging healthy ecosystem in their sustainable building. Clearly the level of user knowledge about a sustainable building and its technologies makes a difference about the actual behaviour towards sustainable buildings (Knott 2007, Stenberg 2007) There remains two major challenge faced by sustainable building occupants: (i) addressing the gap between an occupant's expectations of sustainable building outcomes and what the building actually provides and (ii) overcoming the lack of user knowledge about sustainability design and operation for a particular with regards to performance (Jailani et. al, 2011). This is an innovative study designed to address these challenges. It uses a focus group approach to investigate the gap between (a) user expectations and (b) sustainable building performance, with reference to the relationship between interactive learning process and the level of implementation of sustainability in commercial buildings. The outcome from the study will provide a post-occupancy evaluation of the perception of occupants in sustainable buildings. Most importantly, this information can then assist architects and designers in private and government organisations to successfully develop future sustainable design and policy which can fully capitalise on the original intention when delivering sustainable buildings, as well as providing an innovative feedback mechanism between occupiers and architects.

Patient participation in nursing care on medical wards: An integrative review

BACKGROUND: Patient participation is a way for patients to engage in their nursing care. In view of the possible link between patient participation and safety, there is a need for an updated review to assess patient participation in nursing care. OBJECTIVES: To investigate patients' and nurses' perceptions of and behaviours towards patient participation in nursing care in the context of hospital medical wards. DESIGN: Integrative review. DATA SOURCES: Three search strategies were employed in August 2013; a computerised database search of Cumulative Index of Nursing and Allied Health Literature, Cochrane Library, Medline and PsychINFO; reference lists were hand-searched; and forward citation searching was executed. REVIEW METHODS: After reviewing the studies, extracting study data and completing summary tables the methodological quality was assessed using the Mixed-Methods Assessment Tool by two reviewers. Reviewers met then to discuss discrepancies as well as the overall strengths and limitations of the studies. Discrepancies were overcome through consensus or a third reviewer adjudicated the issue. Within and across study analysis and synthesis of the findings sections was undertaken using thematic synthesis. RESULTS: Eight studies met inclusion criteria. Four themes were identified - enacting participation, challenges to participation, promoting participation and types of participation. Most studies included were conducted in Europe. The majority of studies used qualitative methodologies, with all studies sampling patients; nurses were included in three studies. Data were largely collected using self-reported perceptions; two studies included observational data. Methodological issues included a lack of reflexivity, un-validated data collection tools, sampling issues and low response rates. CONCLUSIONS: On medical wards, patients and nurses desire, perceive or enact patient participation passively. Challenging factors for patient participation include patients' willingness, nurses' approach and confusion around expectations and roles. Information-sharing was identified as an activity that promotes patient participation, suggesting nurses encourage active communication with patients in practice. Involving patients in assessment and care planning may also enhance patient participation. For education, enhancing nurses' understanding of the attributes of patient participation, as well as patient-centred care approaches may be beneficial for medical ward nurses. From here, researchers need to examine ways to overcome the barriers to patient participation; further nurse participants and observational data is required on medical wards.

Patients' perceptions of participation in nursing care on medical wards

BACKGROUND: Patient participation benefits the patient and is a core concept of patient-centred care. Patients believe in their ability to prevent errors; thus, they may play a vital role in combating adverse event rates in hospitals. AIMS AND OBJECTIVES: To explore hospitalised medical patients' perceptions of participating in nursing care, including the barriers and facilitators for this activity. RESEARCH METHODS: This interpretive study was conducted on four medical wards, in two hospitals. Purposeful maximum variation sampling was operationalised to recruit patients that differed in areas such as age, gender and mobility status. In-depth semi-structured audiotaped interviews were undertaken and analysed using inductive content analysis. RESULTS: Twenty patients participated in the study. Four categories were uncovered in the data. First, valuing participation showed patients' willingness to participate, viewing it as a worthwhile task. Second, exchanging intelligence was a way of participating where patients' knowledge was built and shared with health professionals. Third, on the lookout was a type of participation where patients monitored their care, showing an attentive approach towards their own safety. Fourth, power imbalance was characterised by patients feeling their opportunities for participation were restricted. CONCLUSIONS: Patients were motivated to participate and valued participation. Cultivating this motivation may be crucial to patient empowerment and practices of safety monitoring, a fundamental strategy to addressing patient safety issues in hospitals. Engaging nurse-patient relationships, inclusive of knowledge sharing, is required in practice to empower patients to participate. Educating patients on the consequences of non-participation may motivate them, while nurses may benefit from training on patient-centred approaches. Future research should address ways to increase patient motivation and opportunities to participate.

Growth inhibition of Candida species and Aspergillus fumigatus by statins

Statins are a class of drugs widely used for lowering high cholesterol levels through their action on 3-hydroxy-3-methylglutaryl-CoA reductase, a key enzyme in the synthesis of cholesterol. We studied the effects of two major statins, simvastatin and atorvastatin, on five Candida species and Aspergillus fumigatus. The statins strongly inhibited the growth of all species, except Candida krusei. Supplementation of Candida albicans and A. fumigatus with ergosterol or cholesterol in aerobic culture led to substantial recovery from the inhibition by statins, suggesting specificity of statins for the mevalonate synthesis pathway. Our findings suggest that the statins could have utility as antifungal agents and that fungal colonization could be affected in those on statin therapy.

Nurses' views of patient participation in nursing care

AIMS: To explore nurses' views of patient participation in nursing care on medical wards. BACKGROUND: Nurses have frequent contact with patients, highlighting their potential role in enabling patient participation. However, some nurses' actions and attitudes act as barriers, failing to achieve core requirements of patient participation. Discovering nurses' views may assist in developing strategies to encourage patient participation in hospitals. DESIGN: Interpretive study. METHODS: Twenty nurses were recruited from four medical wards, located in two Australian hospitals. In-depth semi-structured interviews were conducted between November 2013-March 2014 and analysed using content analysis. FINDINGS: Five categories emerged from the nurses' views. The first category, acknowledging patients as partners, showed nurses respected patients as legitimate participants. In the second category, managing risk, nurses emphasized the need to monitor participation to ensure rules and patient safety were maintained. Enabling participation was the third category, which demonstrated nurses' strategies that enhanced patients' participation. The fourth category was hindering participation; encapsulating nurses' difficulty in engaging patients with certain characteristics. In the final category, realizing participation, nurses believed patients could be involved in physical activities or clinical communication. CONCLUSION: Nurses have a crucial role in promoting patient participation. Through acknowledging and enabling participation, nurses may facilitate patient participation in a range of nursing activities. The nurse's role in enacting participation is complex, having to accommodate each patient's risks and characteristics, highlighting the need for good assessment skills. Education, policy and research strategies are essential to foster nurses' pivotal role in patient participation.

Aggression-related alcohol expectancies and barroom aggression among construction tradespeople

INTRODUCTION AND AIMS: Few studies have investigated the relationship of barroom aggression with both general and barroom-specific alcohol expectancies. The present study investigated these associations in a rarely studied and high-risk population: construction tradespeople. DESIGN AND METHODS: Male construction tradespeople (n = 211) aged 18-35 years (M = 21.91, SD = 4.08 years) participated in a face-to-face questionnaire assessing general and barroom-specific alcohol expectancies and perpetration of physical and verbal barroom aggression as well as control variables, age, alcohol consumption and trait aggression. RESULTS: Sequential logistic regression analyses revealed that general alcohol-aggression expectancies of courage or dominance were not predictive of either verbal or physical barroom aggression after controlling for age, alcohol consumption and trait aggression. However, barroom-specific alcohol expectancies were associated with both verbal and physical barroom aggression, with positive associations found for expected hyper-emotionality and protective effects for expected cognitive impairment. DISCUSSION AND CONCLUSIONS: In a population where rates of risky drinking and barroom aggression are high, specific expectations about the effects of drinking in bars may influence subsequent aggressive behaviour in bars.

Patient and nurse preferences for nurse handover-using preferences to inform policy: a discrete choice experiment protocol

INTRODUCTION: Nursing bedside handover in hospital has been identified as an opportunity to involve patients and promote patient-centred care. It is important to consider the preferences of both patients and nurses when implementing bedside handover to maximise the successful uptake of this policy. We outline a study which aims to (1) identify, compare and contrast the preferences for various aspects of handover common to nurses and patients while accounting for other factors, such as the time constraints of nurses that may influence these preferences.; (2) identify opportunities for nurses to better involve patients in bedside handover and (3) identify patient and nurse preferences that may challenge the full implementation of bedside handover in the acute medical setting. METHODS AND ANALYSIS: We outline the protocol for a discrete choice experiment (DCE) which uses a survey design common to both patients and nurses. We describe the qualitative and pilot work undertaken to design the DCE. We use a D-efficient design which is informed by prior coefficients collected during the pilot phase. We also discuss the face-to-face administration of this survey in a population of acutely unwell, hospitalised patients and describe how data collection challenges have been informed by our pilot phase. Mixed multinomial logit regression analysis will be used to estimate the final results. ETHICS AND DISSEMINATION: This study has been approved by a university ethics committee as well as two participating hospital ethics committees. Results will be used within a knowledge translation framework to inform any strategies that can be used by nursing staff to improve the uptake of bedside handover. Results will also be disseminated via peer-reviewed journal articles and will be presented at national and international conferences.
