AbstractTraditional concepts of civic education in the United States and the expanding horizons curriculum scope and sequence are challenged by globalization and transnationality because new understandings of citizenship are emerging. In our conceptual analysis, we reconceptualize social studies curriculum for childhood to meet these changes. First, we propose a theoretical framework synthesizing literature in the areas of multicultural, global, and democratic education. Second, we propose opening curriculum and research to the voices of students, especially transnational students. Such reconceptualizations have important implications for a social studies curriculum for childhood that is socially just and responsive to the changing sizes, types, and qualities of the communities with which students engage.

Purpose The purpose of this paper is to examine competing assumptions about the nature of resilience and selects those most appropriate for an entrepreneurial context. Assumptions are integrated into a theoretical framework highlighting how different threats require different resilience responses. Overall organizational resilience results from a portfolio of resilience capabilities. Design/methodology/approach Akin to theoretical sampling, the authors identify various theoretical insights about resilience across three disciplines of psychology, ecology and engineering. The authors use these insights to distill competing assumptions about what resilience is and evaluate those most appropriate for entrepreneurial contexts. Existing resilience literature in organization science is critiqued in terms of underlying assumptions and an alternative theoretical framework proposed based on more robust assumptions. Findings Other disciplines point to resilience being a process that differs for different threats and as either bouncing back, absorbing shocks or bouncing forward. When imported into entrepreneurship these characteristics lead to a conceptualization of resilience as being enacted through a capability portfolio. A routine-based capability response is preferred when threats are familiar, simple, not severe and frequent, following minimal disorganization and where resource slack is available. In contrast, heuristics-based capabilities are preferred when threats are unfamiliar, complex, severe and infrequent, following serious disorganization and where resource slack is unavailable. An absorption threshold point identifies when organizations need to switch from routine-based to heuristics-based resilience capabilities. Practical implications Building resilience across a range of adverse situations requires firms to develop a portfolio of resilience capabilities. Firms must learn to match the capability required for the specific threat profile faced. This includes a mix of routinized responses for returning to stability but also more flexible, heuristics-based responses for strategic reconfiguration. Originality/value The paper undertakes a first of its kind cross-disciplinary conceptual analysis at the level of identifying competing assumptions about the nature of resilience. These assumptions are found to be somewhat unconscious among organization researchers, limiting the conceptual development of resilience in entrepreneurship. The authors contribute a theoretical framework based on explicit and robust assumptions, enabling the field to advance conceptually.

The ‘healthy buildings’ movement has emerged in response to increasing recognition that many indoor environments, particularly office spaces, have a negative impact upon the wellbeing and productivity of the building users. However, the move towards healthier working environments is hampered by the fact that the academic workplace literature lacks a suitable theoretical framework for representing the complex and dynamic nature of the relationship between the employee and the workplace environment. Therefore, the major objective of this research project was to develop and validate a theoretical framework to represent the employee-workplace relationship. A programme of primary research conducted within industry followed the initial development of framework, further confirming its utility for both research and practice. First, a comprehensive multidisciplinary literature review was conducted, leading to the initial development of the novel conceptual framework to represent the ways in which employees are affected by, and act upon, their workplace environment. The Environmental Demands-Resources (ED-R) framework conceptualises the workplace environment as a composite of pathogenic demands (i.e., aspects of the workplace which cause strain and negatively affect employees) and salutogenic resources (i.e., aspects of the workplace which support employee motivation and engagement). A conceptual analysis of the multidisciplinary workplace literature confirms that these concepts are common across seemingly disparate strands of workplace research. Subsequently, a series of five primary research studies (culminating in six published outputs) was conducted. Two studies explored how requirements for the workplace are moderated by individual differences, finding that what constitutes an environmental demand or resource differs from employee to employee (e.g., noise-sensitive employees are less suited to open-plan offices). Two studies explored the use of environmental sensor data to identify environmental demands and predict employee discomfort, leading to the development of a methodology to combine objective building data with subjective human responses. Finally, one study explored the use of innovative biophilic design as a novel environmental resource, finding that a ‘regeneration pod’ more effectively facilitated recovery from work stress than an ordinary meeting room. This thesis presents the results of those studies in full. First, an introduction to the research topics is presented, followed by a description of the key theoretical constructs and a narrative review and conceptual analysis of the multidisciplinary workplace literature. Then, the six research articles comprising the main programme of primary research are summarised and discussed. Finally, the theoretical and practical implications of the research are considered, with a particular focus on the ways in which the research contributes to effective strategies for the creation and maintenance of workplace environments which better support the health, wellbeing, and productivity of their users.

AbstractUnder the label of scientific metaphysics, many naturalist metaphysicians are moving away from a priori conceptual analysis and instead seek scientific explanations that will help bring forward a unified understanding of the world. This paper first reviews how our classical assumptions about ordinary objects fail to be true in light of quantum mechanics. The paper then explores how our experiences of ordinary objects arise by reflecting on how our neural system operates algorithmically. Contemporary models and simulations in computational neuroscience are shown to provide a theoretical framework that does not conflict with existing fundamental physical theories, and nonetheless helps us make sense of the manifest image. It is argued that we must largely explain how the manifest image arises in algorithmic terms, so that we can pursue a metaphysics about ordinary objects that is scientifically well founded.

This study aims to explore the metaphors of fire and hell from Holy Qur'ān utilizing conceptual analysis and by keeping in view the discussion of cognitive linguistic and cognitive perspectives of metaphor. This research has attempted to apply the semasiological approach to Qur'ānic corpus wherewith the figurative significance of fire and hell is linked with Fire/Hell as a metaphor in the Holy Scripture. The Cognitive Theory of Metaphor (CMT)interpreted by linguists Lakoff & Johnson (1980) and developed later by Lakoff and Turner (1989), and others, e.g. Wreth (1994, 1999)  has been applied as the theoretical framework and the translations of specific extracted verses of Holy Qur'ān are interpreted logically and compared with concerning religious aspects. Originally the principles of Cognitive Metaphor Theory have been employed for the study of Conceptual Metaphorical Analysis (CMA) revealing how metaphors of fire and hell have been used creatively affecting the understanding of much broader aspects of life in light of the teachings of Qur'ān. The tenor and vehicle illustration is taken from I.A Richards’ concept of ground, tenor, and vehicle, and the source and target domain are also debated to bring forth a holistically semasiological understanding after the analysis of the metaphors.

Summary This article focuses on a dogmatic reflection on the concept and function of evidence in civil proceedings. To this end, it addresses evidence as the object of instruction as well as a number of problems associated with the burden of proof. This analysis also deals with the dialectics between the burden of proof and the burden of claim. The reflection we propose on the concetual basis of the evidence also covers questions relating to the instructional activity, the value of the evidence, the binding force of the means of proof and its limitations. From the theoretical framework described, it is also fundamental to proceed to the methodological classification of the test, also questioning its extra procedural value, always seeking to find foundations in the principles underlying the instructional activity. Key words: civil procedure, proof, instruction, allegation.

The concept of ego has various meanings in the field of psychology, depending on the paradigmatic and theoretical framework point of departure. The ego phenomenon as operationalized and measured in the theoretical framework of goal orientation will be the contextual framework for a historical conceptual analysis. In the past three decades, research in the theoretical framework of goal orientation has revealed a positive relationship between ego involvement and the tendency to use the prohibited substances to enhance performance in sport. The concept of the ego phenomenon as operationalized within goal orientation theory and meanings attached to the concept can be connected to the historic oriental writings that were written ~2,500 years ago. These attached meanings to the ego phenomenon include elements of extreme competitiveness and outcome orientation, as well as social comparisons and the external norms for the measurement of success and failure. These meanings can be traced back to the classical works involving the Bhagavad Gita, the Tao Te Ching, and the Eastern Origins of Mindfulness that are part of the broader Buddhist philosophical system. Meister Eckhart, a 12th century German theologian, in his significant contribution on the analysis of the having mode as opposed to the being mode also provides insight into the ego phenomenon that can explain why the ego phenomenon can be linked to some of the deeper psychological motives of using the prohibited substances. The researchers in psychology do not yet have a full understanding of why certain athletes dope or have a susceptibility to use the prohibited substances or performance enhancing drugs (PEDs) and thus the motivation for this historical conceptual analysis of the ego phenomenon. Therefore, this article aimed to deepen the understanding of psychological motives of the athletes who exhibit tendencies toward cheating in general and the proclivity to use the prohibited substances.

Abstract Gilead et al. state that abstraction supports mental travel, and that mental travel critically relies on abstraction. I propose an important addition to this theoretical framework, namely that mental travel might also support abstraction. Specifically, I argue that spontaneous mental travel (mind wandering), much like data augmentation in machine learning, provides variability in mental content and context necessary for abstraction.

We have already described (1.2.3) a device using a pockel's effect light valve as a microscopical electron image converter. This converter can be read out with incoherent or coherent light. In the last case we can set in line with the converter an optical diffractometer. Now, electron microscopy developments have pointed out different advantages of diffractometry. Indeed diffractogram of an image of a thin amorphous part of a specimen gives information about electron transfer function and a single look at a diffractogram informs on focus, drift, residual astigmatism, and after standardizing, on periods resolved (4.5.6). These informations are obvious from diffractogram but are usualy obtained from a micrograph, so that a correction of electron microscope parameters cannot be realized before recording the micrograph. Diffractometer allows also processing of images by setting spatial filters in diffractogram plane (7) or by reconstruction of Fraunhofer image (8). Using Electrotitus read out with coherent light and fitted to a diffractometer; all these possibilities may be realized in pseudoreal time, so that working parameters may be optimally adjusted before recording a micrograph or before processing an image.
