- The current focus in Swedish policy towards national security and high-end technical systems, together with a rapid development in multispectral sensor technology, adds to the utility of developing advanced materials for spectral design in signature management applications. A literature study was performed probing research databases for advancements. Qualitative text analysis was performed using a six-indicator instrument: spectrally selective reflectance; low gloss; low degree of polarization; low infrared emissivity; non-destructive properties in radar and in general controllability of optical properties. Trends are identified and the most interesting materials and coating designs are presented with relevant performance metrics. They are sorted into categories in the order of increasing complexity: pigments and paints, one-dimensional structures, multidimensional structures (including photonic crystals), and lastly biomimic and metamaterials. The military utility of the coatings is assessed qualitatively. The need for developing a framework for assessing the military utility of incrementally increasing the performance of spectrally selective coatings is identified.

Tidskriftsartikel (refereegranskat)abstract
- A concept called Military Utility is proposed for the study of the use of technology in military operations. The proposed concept includes a three-level structure representing key features and their detailed components. On basic level the Military Utility of a technical system, to a military actor, in a specific context, is a compound measure of the military effectiveness, of the assessed technical system's suitability to the military capability system and of the affordability. The concept is derived through conceptual analysis and is based on related concepts used in social sciences, the military domain and Systems Engineering. It is argued that the concept has qualitative explanatory powers and can support military decision-making regarding technology in forecasts, defense planning, development, utilization and the lessons learned process. The suggested concept is expected to contribute to the development of the science of Military-Technology and to be found useful to actors related to defense.

- The aim of this article is to present how Chinese strategies are manifested into offensive cyberspace operations targeting Sweden. It is commonly known that People’s Republic of China (PRC, and in this definition the meaning of thegovernment and its military), uses five-year plans (FYP) for social and economic steering strategy of their country. This has been going on since 1953 until today. In 2015, the national strategic plan Made in China 2025 (中国制造2025) was launched by Le Keqiang, the Premier of the State Council of PRC. The main goal with this plan is to strengthen the economic development. In addition, Chinese military strategists noted the importance of information warfare and intelligence during military operations. This article is based on open sources: the official English translated version of the 13th Five-year plan (FYP) and other reporting on cyberspace operations linked to the PRC. A number of cases are presented to highlight the link between the PRC FYP and their targets. Next, the current situation in Sweden is presented and how the country is targeted by PRC-linked activities, both in and through cyberspace, but also military infiltration on academia. The results show that Sweden has been, and is continuously the target of offensive cyberspace operations. In parallel, the country is also the target of military infiltration on the academia, and direct investment strategies such as Huawei attempting to compete for the 5G frequency actions arranged by the Swedish Post and Telecom Authority. In conclusion, Sweden will continue to experience cyberespionage from PRC on all levels and on all domains; science, technology, IP and privacy information theft. Previously unveiled cyberspace operations cases in this article have proven to be a convenient strategy for the PRC to reduce its research and development gap in several ways; innovatively, financially and to shortening the time-to-market (TTM).

- The purpose of this work in progress paper is to report on the method development of the Shared Prioritiesmeasure to include content analysis, as a way of gaining a deeper understanding of team work incrisis/emergency response. An experiment is reported where the performance of six trained teams is comparedwith the performance of six non-trained teams. The experiment was performed using an emergency responsemicroworld simulation with a forest fire scenario. Dependent measures were simulation performance, the CrewAwareness Rating Scale (CARS), and content analysis. Trained teams performed better and scored higher onmeasures of team behaviors.

- Objective, easy to use, and easy to comprehend assessment methods for measuring shared understanding in teams are hard to find. This paper describes an experiment where a measure called Shared Priorities, which is based on ranking of self-generated strategic items, is assessed. Trained teams were compared to non-trained teams in a dynamic problem-solving task. The maturity of the participating teams was also assessed using a content analysis measure. The Shared Priorities measure was used alongside other well-documented measures of team awareness based on self-rating. Results show that the Shared Priorities measure correlates with task performance and could also distinguish between trained and non-trained teams. However, the Shared Priorities measure did not correlate with the other team measures (cf. CARS – Crew Awareness Rating Scale – and DATMA – Distributed Assessment of Team Mutual Awareness), suggesting that it captures a different quality of teamwork than the self-rating measures. Further, the Shared Priorities measure was found to be easily administered.

- A command and control environment is a dynamic and complex setting with complicated technical systems where teams of operators interact to reach shared goals. This study presents an experiment in which we, by means of Structural Equation Modeling (SEM), explain the relations between basic concepts of command and control environments: mental workload, frustration, situational awareness, and performance. This paper reports a LISREL analysis of the Baroutsi, Berggren, Nählinder, & Johansson (2013) data. From that data, a new latent variable “Frustration” emerges, which now can be included in the model.

- Objective, easy to use, easy to comprehend, high face-validity assessment methods for measuring shared awareness in teams are hard to find. This paper describes an experiment where a new measure called Shared Priorities, which is based on ranking of self-generated strategic items, is tested. Trained teams were compared to non-trained teams in a dynamic problem-solving task in terms of performance and shared awareness. The shared priorities measure was used alongside other, well-documented measures of team awareness based on self-rating. The results show that the Shared Priorities measure correlate with performance and could also distinguish between trained and non-trained teams. However, the Shared Priorities measure did not correlate with the other team measures, suggesting that it captures a different quality of team work than the self-rating measures. Further, the shared priorities measure was found to be easily administered and gained a high user acceptance.

- BackgroundIn the rapid development in prehospital medicine the awareness of the many challenges in prehospital care is important as it highlights which areas need improvement and where special attention during education and training should be focused. The purpose of this study is to identify challenges that physicians face when working in the prehospital environment. The research question is thus; what challenges do physicians face when working in prehospital care?MethodThis is a qualitative study with an inductive approach and is based on individual interviews. The interviews were analyzed using the Classic Grounded Theory (GT) method as an approach. The interviews were conducted as semi-structured interviews via the digital platform Zoom during winter / early spring 2022.ResultsChallenges for prehospital physicians can be understood as a process that involves a balancing act between different factors linked to the extreme environment in which they operate. This environment creates unique challenges not usually encountered in routine hospital practice, which results in trade-offs that they would not otherwise be faced with. Their individual situation needs to be balanced against organizational conditions, which means, among other things, that their medical decisions must be made based on limited information as a result of the constraints that exist in the prehospital environment. They must, both as individuals and as part of a team, maneuver in time and space for decision-making and practical tasks. This theory of balancing different entities is based on four themes; thus the theory is the relation between the four themes: leadership, environment, emotion management and organization.ConclusionsWith the help of previous studies and what we have found, it is reasonable to review what training is needed before starting to work prehospital as a physician. This should include components of the themes we have described: organization, environment, leadership and emotional management.

- The purpose of the study was to investigate the influence of flotation REST upon skilled and less skilled golfers’ anxiety in terms of physiological indicators of stress, self-rated anxiety scores, muscle tension, and the effect on golf putting. Prior to performing the putting task participants underwent a treatment of flotation REST or a period of resting in an armchair. Participants completed both treatments in a randomized order with a two-week interval. The results showed that both flotation REST and the armchair treatment reduced systolic blood pressure and heart rate, with no differences between treatments or athlete skill levels. No significant differences between treatments were revealed regarding self-ratings, level of muscle tension or putting precision. The results indicate that flotation REST may be useful for reducing negative symptoms related to stress and anxiety in general; however, no support for direct positive effects on golf performance were found.
