3D virtual building models are used to help clients reach decisions during concept and detailed design phases. However, previously published research provides evidence for discrepancies between human perception of virtual and physical spaces; thus perceiving each virtual dimension (height, width, depth) differently from its physical counterpart, with varying percentages. This can affect clients' effective decision-making during coordination if 3D virtual representations are not perceived identical to their physical equivalent. This paper discusses the impact of these discrepancies beyond the design phases and into the whole lifecycle, construction and operations. Moreover, descriptive and inferential statistical analysis provides evidence of relationships between the physical and virtual perception differences in dimension, discussing possible factors contributing to perception discrepancies affecting the individual viewer, in 2 main areas 1) 3D authoring software 2) psychophysical factors. Possible solutions are also proposed to accommodate for the discrepancy between physical and virtual spaces.

Objectives: Health technology assessment (HTA) yields information that can be ideally used to address deficiencies in health systems and to create a wider understanding of the impact of different policy considerations around technology reimbursement and use. The structure of HTA programs varies across different jurisdictions according to decision-maker needs. Moreover, conducting HTA requires specialized skills. Effective decision making should include multiple criteria (medical, economic, technical, ethical, social, legal, and cultural) and requires multi-disciplinary teams of experts working together to produce these assessments. A workshop explored the multi-disciplinary skills and competencies required to build an effective and efficient HTA team, with a focus on low- and middle-income settings.Methods: This proceeding summarizes main points from a workshop on capacity building, drawing on presentations and group discussions among attendees including different points of view.Results and Conclusions: The workshop and thus this study would have benefited from a larger variety of stakeholders. Therefore, the conclusions arising from the workshop are not the opinion of a representative sample of HTA professionals. Nonetheless, organizations and speakers were carefully selected to provide a valuable approach to this theme. Thus, these proceedings highlight some of the gaps and needs in the education and training programs offered worldwide and calls for further investigation.

Building performance evaluations (BPEs) were carried out for nine Canadian green buildings using a standardised assessment framework. The aim was to explore and measure the discrepancies between the operational performance of the buildings and their predicted performance, as well as to identify lessons for their owners, design teams and the construction industry. The objective of this paper is not to report individual buildings in detail (we refer the reader to the individual building reports) but to report on some general lessons that came from doing this study. Overall these buildings performed well compared to benchmarks. However, the findings suggest that occupancy is not well understood and often incorrectly predicted during design, and that this affects various aspects of performance, including energy and water use. Also energy and water use modelling is often undertaken principally for building code/green rating compliance purposes and does not necessarily represent an accurate prediction of likely operational use. Combined with variations in occupancy this can lead to considerable discrepancies in performance from the modelled values. This may be understood by experts but is often misleading to building owners and others. Water use is often not well predicted and also not carefully managed in buildings and there is a lack of understanding of what constitutes good water performance. Overall, it is important to recognise that each building has its own individual “story” that provides necessary context for effective management and improvement of the building during its ongoing life. It is proposed that a BPE process allows that context to be better understood, and enables more effective decision making about building management, improvements, occupant satisfaction, energy use, etc.

This chapter synthesizes empirical research from multiple disciplines about the use of GIS for decision-making in business settings. Todd & Benbasat’s model (2000) was used as a theoretical framework to identify the variables that have been studied on decision-making at the individual and collaborative level. An extensive literature review in the fields of Information Science, GIS and Decision Science from 1990 to 2002 was conducted with a total of nine studies identified in six journals and two conferences. The scarcity of published research suggests that the impact of GIS on the decision-making process has not been extensively investigated. Moreover, researchers have paid more attention to the study of GIS to support individual decision makers. The effects of variables like desired effort and decision strategy remain unexplored. More empirical work is needed to understand the impact of DSS capabilities, decision maker, task, and decision strategy on decision performance.

The final and concluding chapter summarizes the main points raised in the previous chapters confirming the presence of religious criticisms and disengagements while also emphasizing the difficulties in gaining an accurate knowledge of the extent those two phenomena are widespread in Saudi society. The chapter also highlights the layman’s criticism of religion and contrasts it with that of the intellectual, philosopher or theologian and states the need to pay more attention to the former as it is more representative of most religious criticisms, more indicative of the impact of modern sensibilities on the relationship between Muslims in general and their religiosity, and is motivated by different reasons least of which are ideas. The chapter states the main learnings gained about the phenomenon of criticizing religion in Saudi Arabia and its public emergence in virtual spaces, while also stressing the challenges of the migration of public virtual criticism into public dialogue in physical spaces. Moreover, it points to some of the learnings gained about disengagement from religion in terms of causes and outcomes. Finally, it points to some of the questions left unanswered that need further research.

Bringing the olive harvest period forward leads to storing fruit in field temperatures that risk jeopardizing its quality. Knowledge about the bio-thermal characteristics of olives is crucial when considering their cooling, although published research on the subject is limited. In this work, the cooling rate of the fruit of six olive cultivars has been empirically determined by measuring the evolution of their low temperature under controlled conditions by thermal imaging. Based on these data, the cooling time needed to cool the fruit to 22 °C was estimated, considering the biometric characteristics of the individual fruit, a field temperature from 26 to 42 °C, and a room cooling temperature from −8 to −20 °C. The results showed differences among the cultivars and the need to further investigate the specific heat requirements for small varieties and the impact of the conduction factor on the heavier ones. The simulation suggests that between 2 min (for the light Arbequina and Koroneiki cultivars) and 5 min (for the heavier Verdial and Gordal cultivars) suffice to cool the fruit to the desired temperature with a room temperature of −16 °C. These results show the feasibility of developing technological solutions for cooling olives before their industrial processing with industrial applications such as cooling tunnels on individual fruit.

The adaptive immune system was sculpted to protect individuals, societies, and species since its inception, developing effective strategies to cope with emerging pathogens. Here, we show that similar successful or failed dynamics govern personal and societal responses to a pathogen as SARS-CoV2. Understanding the self-similarity between the health-protective measures taken to protect the individual or the society, help identify critical factors underlying the effectiveness of societal response to a pathogenic challenge. These include (1) the quick employment of adaptive-like, pathogen-specific strategies to cope with the threat including the development of “memory-like responses”; (2) enabling productive coaction and interaction within the society by employing effective decision-making processes; and (3) the quick inhibition of positive feedback loops generated by hazardous or false information. Learning from adaptive anti-pathogen immune responses, policymakers and scientists could reduce the direct damages associated with COVID-19 and avert an avoidable “social cytokine storm” with its ensuing socioeconomic damage.

The purpose of the work is to investigate the formation of information culture as a defining characteristic of modern communicative practices and socio-cultural existence of man in the digital environment. The research methodology consists in the application of analytical, semiotic, systemic, culturological methods in the study of information as a fundamental factor in the formation of information culture and in general the digital environment of the information society. Information is a subsystem capable of transforming all spheres of society, while forming the needs and skills in obtaining, processing and transmitting information. Oversaturation and rapid circulation of information encourages the introduction of the concept of information culture, which can become a cognitive filter in the selection of information. The scientific novelty of the work is to expand information on the impact of information on the deepening of socio-cultural competencies, the level of socialization and education of the individual due to the information factor, as well as the ability to resist the negative effects of information on society in various forms. Information culture should become the core of the modern digital environment not only as an indicator of literacy and competence, but also as a general worldview vector that can influence the explanation of reality, commenting on current events, promoting important norms and values. Conclusions. In recent decades, information culture has become increasingly relevant as a phenomenon generated by the information society, mediated by Internet communication and modern communication practices in general. The development of modern digital information space generates a huge amount of information that is transmitted from person to person, but, at the same time, grows into a social phenomenon that shapes the thinking, behavior and actions of communities. The information culture of society becomes tangential and affects various spheres of life, which can no longer be understood and defined outside the information context, while serving as an effective factor in human perception of the surrounding reality, the world at large. Information culture is directly related to the social nature of the individual, due to the relevant values ​​and worldviews. Modern information culture is inextricably linked with technological progress and means of communication, which are the determining factors of social development that can influence the way of social life and worldview. Thus, the formation of information culture of society becomes an important and continuous process, mediated by the influence of information of human existence. Key words: information, information culture, communicative practices, communication, digitalization, information society.

Background As the role of a health care system’s influence on nurse burnout becomes better understood, an under-standing of the impact of a nurses’ work environment on burnout and well-being is also imperative. Objective To identify the key elements of a healthy work environment associated with burnout, secondary trauma, and compassion satisfaction, as well as the effect of burnout and the work environment on nurse turnover. Methods A total of 779 nurses in 24 critical care units at 13 hospitals completed a survey measuring burnout and quality of the work environment. Actual unit-level data for nurse turnover during a 5-month period were queried and compared with the survey results. Results Among nurses in the sample, 61% experience moderate burnout. In models controlling for key nurse characteristics including age, level of education, and professional recognition, 3 key elements of the work environment emerged as significant predictors of burnout: staffing, meaningful recognition, and effective decision-making. The latter 2 elements also predicted more compassion satisfaction among critical care nurses. In line with previous research, these findings affirm that younger age is associated with more burnout and less compassion satisfaction. Conclusions Efforts are recommended on these 3 elements of the work environment (staffing, meaningful recognition, effective decision-making) as part of a holistic, systems-based approach to addressing burnout and well-being. Such efforts, in addition to supporting personal resilience-building activities, should be undertaken especially with younger members of the workforce in order to begin to address the crisis of burnout in health care.

This paper proposes and discusses the need for research into foundation degrees which have been specifically developed for teaching assistants. This is necessary to develop knowledge and understanding due to the deficiency of pertinent research and potential consequences to all those involved. All relevant parties, from policy makers to individuals, need available to them the latest information rooted in knowledge, in order to support effective decision making. The author makes the case for undertaking this research through the interpretive approach, in that the ‘reality’ is what it is construed to be, to be accessed through the adoption of the frame of reference of the participants. By exploring the relevant context of the particular policies, social processes and social structures involved, the impact and association that exists could also be acknowledged, along with the environment in which the relevant population operates. These include those at the macro-level or socio-structural level, the meso-level or institutional/organisational level and at the micro-level or personal/individual perspective. Within these levels, foundation degrees will be discussed, examining their influence on areas such as widening participation and in particular – teaching assistants. It is proposed that the consequences of foundation degrees for teaching assistants may be so significant and wide ranging that it is imperative to research without delay the impact on all those involved.
