3D Imaging of Gems and Minerals by Multiphoton Microscopy

Many optical approaches have been used to examine the composition and structure of gemstones, both recently and throughout history. The nonlinear optical behavior of different gemstones has not been investigated, and the higher order terms to the refractive index represent an unused tool for qualifying and examining a stone. We have used a multiphoton microscope to examine the nonlinear optical properties of 36 different gemstones and demonstrate that it is a useful tool for imaging them three-dimensionally up to the millimeter scale below the sample surface. The polarization dependence of second harmonic generation signals was used to examine the crystal orientations inside the minerals.Comment: 9 pages, five figure

Texture, realism, performance: exploring the intersection of transtexts and the contemporary sitcom

Contemporary US sitcom is at an interesting crossroads: it has received an increasing amount of scholarly attention (e.g. Mills 2009; Butler 2010; Newman and Levine 2012; Vermeulen and Whitfield 2013), which largely understands it as shifting towards the aesthetically and narratively complex. At the same time, in the post-broadcasting era, US networks are particularly struggling for their audience share. With the days of blockbuster successes like Must See TV’s Friends (NBC 1994-2004) a distant dream, recent US sitcoms are instead turning towards smaller, engaged audiences. Here, a cult sensibility of intertextual in-jokes, temporal and narrational experimentation (e.g. flashbacks and alternate realities) and self-reflexive performance styles have marked shows including Community (NBC 2009-2015), How I Met Your Mother (CBS 2005-2014), New Girl (Fox 2011-present) and 30 Rock (NBC 2006-2013). However, not much critical attention has so far been paid to how these developments in textual sensibility in contemporary US sitcom may be influenced by, and influencing, the use of transmedia storytelling practices, an increasingly significant industrial concern and rising scholarly field of enquiry (e.g. Jenkins 2006; Mittell 2015; Richards 2010; Scott 2010; Jenkins, Ford and Green 2013). This chapter investigates this mutual influence between sitcom and transmedia by taking as its case studies two network shows that encourage invested viewership through their use of transtexts, namely How I Met Your Mother (hereafter HIMHM) and New Girl (hereafter NG). As such, it will pay particular attention to the most transtextually visible character/actor from each show: HIMYM’s Barney Stinson, played by Neil Patrick Harris, and NG’s Schmidt, played by Max Greenfield. This chapter argues that these sitcoms do not simply have their particular textual sensibility and also (happen to) engage with transmedia practices, but that the two are mutually informing and defining. This chapter explores the relationships and interplay between sitcom aesthetics, narratives and transmedia storytelling (or industrial transtexts), focusing on the use of multiple delivery channels in order to disperse “integral elements of a fiction” (Jenkins, 2006 95-6), by official entities such as the broadcasting channels. The chapter pays due attention to the specific production contexts of both shows and how these inform their approaches to transtexts. This chapter’s conceptual framework will be particularly concerned with how issues of texture, the reality envelope and accepted imaginative realism, as well as performance and the actor’s input inform and illuminate contemporary sitcoms and transtexts, and will be the first scholarly research to do so. It will seek out points of connections between two (thus far) separate strands of scholarship and will move discussions on transtexts beyond the usual genre studied (i.e. science-fiction and fantasy), as well as make a contribution to the growing scholarship on contemporary sitcom by approaching it from a new critical angle. On the basis that transmedia scholarship stands to benefit from widening its customary genre choice (i.e. telefantasy) for its case studies and from making more use of in-depth close analysis in its engagement with transtexts, the chapter argues that notions of texture, accepted imaginative realism and the reality envelope, as well as performance and the actor’s input deserve to be paid more attention to within transtext-related scholarship

A recently discussed challenge in cyber defence teaching and training is the gap between the fast technological advancement accompanied by rapidly changing demands on future cyber defence operators, and the lack of science-based teaching and training methods. A growing body of evidence suggests a crucial role of human factors as a central predictor for human performance in sociotechnical systems. While this has been acknowledged in a wide range of safety-critical applied fields, there is still a lack of knowledge about the impact of human factors on cyber defence performance. The lack of conventional metrics of performance and learning progress contribute to this deficit. To address this gap, the Norwegian Defence Cyber Academy (NDCA) follows a science-based educational approach that identified in a series of empirical studies cognitive-psychological predictors for learning success of future cyber defence operators. These predictors and elements of a human factors research program are deeply embedded into educational practice and include processes such as metacognition, self-regulation, coping, communication and shared mental modelling. Slow education methods and mentoring are fundamental to enabling the advancement of human factors cognisance among military cyber cadets. As a tool for efficient training, the NDCA developed and implemented a mentoring concept that involves a cyber defence retrospective timeline analysis involving expert and practitioner level mentors. The timeline differentiates between performance relevant hard-and soft-skills and leads progressively towards an alignment of Security Operation Centre (SOC)-and expert judgments of performance. The NDCA argues that this educational concept facilitates educational benefits based on insight, accurate self-perception, motivation and decreased team workloads following more efficient collaboration.publishedVersio

Neurophysiological and Emotional Influences on Team Communication and Metacognitive Cyber Situational Awareness During a Cyber Engineering Exercise

Background: Cyber operations unfold at superhuman speeds where cyber defense decisions are based on human-to-human communication aiming to achieve a shared cyber situational awareness. The recently proposed Orient, Locate, Bridge (OLB) model suggests a three-phase metacognitive approach for successful communication of cyber situational awareness for good cyber defense decision-making. Successful OLB execution implies applying cognitive control to coordinate self-referential and externally directed cognitive processes. In the brain, this is dependent on the frontoparietal control network and its connectivity to the default mode network. Emotional reactions may increase default mode network activity and reduce attention allocation to analytical processes resulting in sub-optimal decision-making. Vagal tone is an indicator of activity in the dorsolateral prefrontal node of the frontoparietal control network and is associated with functional connectivity between the frontoparietal control network and the default mode network. Aim: The aim of the present study was to assess whether indicators of neural activity relevant to the processes outlined by the OLB model were related to outcomes hypothesized by the model. Methods: Cyber cadets (N = 36) enrolled in a 3-day cyber engineering exercise organized by the Norwegian Defense Cyber Academy participated in the study. Differences in prospective metacognitive judgments of cyber situational awareness, communication demands, and mood were compared between cyber cadets with high and low vagal tone. Vagal tone was measured at rest prior to the exercise. Affective states, communication demands, cyber situational awareness, and metacognitive accuracy were measured on each day of the exercise. Results: We found that cyber cadets with higher vagal tone had better metacognitive judgments of cyber situational awareness, imposed fewer communication demands on their teams, and had more neutral moods compared to cyber cadets with lower vagal tone. Conclusion: These findings provide neuroergonomic support for the OLB model and suggest that it may be useful in education and training. Future studies should assess the effect of OLB-ing as an intervention on communication and performance.Neurophysiological and Emotional Influences on Team Communication and Metacognitive Cyber Situational Awareness During a Cyber Engineering ExercisepublishedVersio

Gamification as a neuroergonomic approach to improving interpersonal situational awareness in cyber defense

In cyber threat situations, the establishment of a shared situational awareness as a basis for cyber defense decision-making results from adequate communication of a Recognized Cyber Picture (RCP). RCPs consist of actively selected information and have the goal of accurately presenting the severity and potential consequences of the situation. RCPs must be communicated between individuals, but also between organizations, and often from technical to non-/less technical personnel. The communication of RCPs is subject to many challenges that may affect the transfer of critical information between individuals. There are currently no common best practices for training communication for shared situational awareness among cyber defense personnel. The Orient, Locate, Bridge (OLB) model is a pedagogic tool to improve communication between individuals during a cyber threat situation. According to the model, an individual must apply meta-cognitive awareness (O), perspective taking (L), and communication skills (B) to successfully communicate the RCP. Gamification (applying game elements to non-game contexts) has shown promise as an approach to learning. We propose a novel OLB-based Gamification design to improve dyadic communication for shared situational awareness among (technical and non-technical) individuals during a cyber threat situation. The design includes the Gamification elements of narrative, scoring, feedback, and judgment of self. The proposed concept contributes to the educational development of cyber operators from both military and civilian organizations responsible for defending and securing digital infrastructure. This is achieved by combining the elements of a novel communication model with Gamification in a context in urgent need for educational input.publishedVersio
