When we anticipate enjoyable events or share positive experiences with others we can prolong and amplify our positive emotions. These and other savouring techniques can increase our subjective well-being. Yet, it remains unknown whether practising of diverse savouring techniques adds its own positive effect. In this 1 × 3 randomised controlled trial, 71 participants used a novel, interactive poster to facilitate high vs. low savouring diversity over eight days, or they journaled in the control condition. Unlike other positive psychology interventions (PPIs), the poster was designed to inspire users to self-select their own positive activities. Regression analyses showed that while cognitive well-being increased in the high savouring diversity condition, emotional well-being did not. These results suggested that assigning savouring diversity may have modestly contributed to users’ cognitive well-being. Written responses further convey the poster’s potential effectiveness in promoting positive experiences. Implications for design practice and directions for future research are discussed. 

This two-part article explores the concept of emotional connoisseurship— the art of appreciating lived emotional experiences in emotion-driven design (EDD). In Part 1, we aim to establish and position the concept within the current EDD theoretical landscape. We first review the concept of connoisseurship, its origins, development, and relevance to professional practices. Second, building upon the existing design literature, we scrutinize the relationships between design connoisseurship and design expertise. We then conceptualize emotional connoisseurship as an essential skill that designers aspiring to practice EDD must actively cultivate, along with learning EDD theories, methods, and tools. After that, we reflect on how previous EDD research outcomes (i.e., emotional granularity design tools) can support the development of a designer’s emotional connoisseurship, especially in a schema-oriented or top-down manner, and argue the need for a sensibil- ity-oriented or bottom-up approach. Part 1 sets the stage for Part 2. Part 2 will detail our pedagogical initiative supporting the self-cultivation of emotional connoisseurship among novice designers through a sensibility- oriented approach. 

Nature experiences, especially the visual aspects of nature, have been widely used to facilitate relaxation. Fueled by digital technology, simulated visual nature experiences have gained popularity in creating healing environments that induce relaxation. However, while easily applicable, not all nature-imitating visuals lead to relaxation. How to effectively design relaxing visual nature experiences remains largely unexplored. This paper investigates how different nature qualities facilitate relaxing visual experiences and the roles of two personal characteristics (mood and nature-relatedness) play. Through an online survey and interviews, we assessed 16 nature video clips, representing eight distinctive nature qualities, and compared perceived experiences while considering the influence of personal characteristics. The results indicate four types of visual qualities (engaging, instinctive, ambient, and derivative) underlying nature-induced relaxation, and show that nature relatedness influences the degree to which nature video clips elicit relaxation. We discuss design implications for creating personalized digital nature. 

ABSTRACT We present deep far-infrared observations of the nearby edge-on galaxy NGC 891 obtained with the Herschel Space Observatory and the Spitzer Space Telescope. The maps confirm the detection of thermal emission from the inner circumgalactic medium (halo) and spatially resolve a dusty superbubble and a dust spur (filament). The dust temperature of the halo component is lower than that of the disc but increases across a region of diameter ≈8.0 kpc extending at least 7.7 kpc vertically from one side of the disc, a region we call a superbubble because of its association with thermal X-ray emission and a minimum in the synchrotron scale height. This outflow is breaking through the thick disc and developing into a galactic wind, which is of particular interest because NGC 891 is not considered a starburst galaxy; the star formation rate surface density, 0.03 M⊙ yr−1 kpc−2, and gas fraction, just $$10{{\ \rm per\ cent}}$$ in the inner disc, indicate the threshold for wind formation is lower than previous work has suggested. We conclude that the star formation surface density is sufficient for superbubble blowout into the halo, but the cosmic ray electrons may play a critical role in determining whether this outflow develops into a fountain or escapes from the gravitational potential. The high dust-to-gas ratio in the dust spur suggests the material was pulled out of NGC 891 through the collision of a minihalo with the disc of NGC 891. We conclude that NGC 891 offers an example of both feedback and satellite interactions transporting dust into the halo of a typical galaxy. 

The ALICE Collaboration reports measurements of the large relative transverse momentum ( $k_T$) component of jet substructure in $pp$and Pb-Pb collisions at center-of-mass energy per nucleon pair $\sqrt{s_{\mathrm{NN}}}=5.02\mathrm{TeV}$. Enhancement in the yield of such large- $k_{\mathrm{T}}$emissions in head-on Pb-Pb collisions is predicted to arise from partonic scattering with quasiparticles of the quark-gluon plasma. The analysis utilizes charged-particle jets reconstructed by the anti- $k_{\mathrm{T}}$algorithm with resolution parameter $R=0.2$in the transverse-momentum interval $60<p_{\mathrm{T},\mathrm{ch},\mathrm{jet}}<80\mathrm{GeV}/c$. The soft drop and dynamical grooming algorithms are used to identify high transverse momentum splittings in the jet shower. Comparison of measurements in Pb-Pb and $pp$collisions shows medium-induced narrowing, corresponding to yield suppression of high- $k_T$splittings, in contrast to the expectation of yield enhancement due to quasiparticle scattering. The measurements are compared to theoretical model calculations incorporating jet modification due to jet-medium interactions (“jet quenching”), both with and without quasiparticle scattering effects. These measurements provide new insight into the underlying mechanisms and theoretical modeling of jet quenching.
