‘Ref! Could You Help Me?’—Building a Positive Climate by Referees during Floorball Competitions in Youth Sport

In creating a positive climate in sport for children and youth, the role of adults is of key importance as their behavior and attitudes determine the experiences and multilateral development of young players. Relatively recently, the importance of the referee in creating a supportive sporting environment has begun to be emphasized. This concerns, in particular, team sports in which the referees interact with players many times and influence the course of the game. The aim of the study was to evaluate the quality of the referee–players’ interactions during youth floorball matches in terms of building a positive climate and responsiveness to the players’ needs. Another aim of the study was to examine whether the referee’s qualifications and players’ gender affect the quality of their interactions with the players. The study was conducted among 21 referees officiating matches for girls and boys aged 12–18. Naturalistic and structured observation methods were used in the study. The observation was conducted using a wireless intercom that allows listening to verbal messages directed to the players. Furthermore, the referee’s work was recorded using a camera. The results of the statistical tests did not show any significant differences in the assessment of referees between the groups distinguished in terms of the referees’ license and players’ gender in both examined dimensions. The observations showed that the average rating of building a positive climate by referees during a sporting event measured on a seven-point scale was ‘poor’ (2.81 pts). The referees were assessed significantly higher on the second dimension (responsiveness to the players’ needs), although an overall rating of 3.81 pts means a medium level of interaction quality. The results indicate areas in which referees can improve. They lead to the following conclusions: (i) the contents of training for floorball referees should include problems of pedagogy and developmental psychology; (ii) referees should be equipped with appropriate competencies for building a positive climate during matches and monitoring the players’ needs; (iii) referees appointed to officiate children and youth games should be characterized by appropriate predispositions.

Effectiveness of Islamic Monetary Policy Transmission on Inflation and Economic Performance

The most crucial part for the economic development of a country is maintaining the stability of inflation to create a positive climate for economic and business activities. A number of efforts can be performed to achieve stable inflation and increase economic growth by designing monetary policy incorporating the variables of Bank Indonesia Sharia Certificate (SBIS), Islamic Interbank Money Market (IIMM), and Financing. Drawing on this issue, the in-hand study aims to examine the effectiveness of Islamic monetary policy transmission, using the instruments of SBIS, IIMM, and Financing, on inflation and economic performance (GDP) from the period of January 2011 to December 2020. Using secondary data, this study employs VAR/VECM approach by the assistance of Eviews program. The results reveal that in the short term period, inflation is significantly influenced by the IIMM, while GDP t is affected by the GDP t-1 and financing activities. In the long term period, both inflation and GDP are determined by SBIS and financing activities. In general, this study results in a conclusion that the variables of IIMM, financing activities, and GDP t-1 influence the economic performance both in short and long term periods. These results contribute as fruitful insights to developing financial strategies and monetary policy to maintain stable inflation and improve economic performance of a country.

Thawing Yedoma permafrost is a neglected nitrous oxide source

In contrast to the well-recognized permafrost carbon (C) feedback to climate change, the fate of permafrost nitrogen (N) after thaw is poorly understood. According to mounting evidence, part of the N liberated from permafrost may be released to the atmosphere as the strong greenhouse gas (GHG) nitrous oxide (N2O). Here, we report post-thaw N2O release from late Pleistocene permafrost deposits called Yedoma, which store a substantial part of permafrost C and N and are highly vulnerable to thaw. While freshly thawed, unvegetated Yedoma in disturbed areas emit little N2O, emissions increase within few years after stabilization, drying and revegetation with grasses to high rates (548 (133–6286) μg N m−2 day−1; median with (range)), exceeding by 1–2 orders of magnitude the typical rates from permafrost-affected soils. Using targeted metagenomics of key N cycling genes, we link the increase in in situ N2O emissions with structural changes of the microbial community responsible for N cycling. Our results highlight the importance of extra N availability from thawing Yedoma permafrost, causing a positive climate feedback from the Arctic in the form of N2O emissions.

Testing Forestry Digital Twinning Workflow Based on Mobile LiDAR Scanner and AI Platform

Climate-smart forestry is a sustainable forest management approach for increasing positive climate impacts on society. As climate-smart forestry is focusing on more sustainable solutions that are resource-efficient and circular, digitalization plays an important role in its implementation. The article aimed to validate an automatic workflow of processing 3D pointclouds to produce digital twins for every tree on large 1-ha sample plots using a GeoSLAM mobile LiDAR scanner and VirtSilv AI platform. Specific objectives were to test the efficiency of segmentation technique developed in the platform for individual trees from an initial cloud of 3D points observed in the field and to quantify the efficiency of digital twinning by comparing the automatically generated results of (DBH, H, and Volume) with traditional measurements. A number of 1399 trees were scanned with LiDAR to create digital twins and, for validation, were measured with traditional tools such as forest tape and vertex. The segmentation algorithm developed in the platform to extract individual 3D trees recorded an accuracy varying between 95 and 98%. This result was higher in accuracy than reported by other solutions. When compared to traditional measurements the bias for diameter at breast height (DBH) and height was not significant. Digital twinning offers a blockchain solution for digitalization, and AI platforms are able to provide technological advantage in preserving and restoring biodiversity with sustainable forest management.

Assessment of Referees in Terms of Building a Positive Climate and Responsiveness to the Health, Emotional, and Social Needs of Rugby Players in Competitive Children Sport

One of the key elements of effective sports programs that contribute to a child’s sense of joy and satisfaction in participating in sports is contact with an adult who builds a caring climate deliberately and intentionally. Referees play a special role in providing positive experiences for young athletes. The main aim of this study was to assess the quality of referee–player interactions in terms of building a positive climate during the game and the referee’s responsiveness to the health, emotional, social, and cognitive needs of young rugby players aged 6–12 years. The research was conducted among 23 referees refereeing children’s rugby matches in Poland. The structure observation method and The Referee–Players’ Interaction Assessment Scoring System tool were used in the study. Each referee was observed twice. The referee’s verbal and non-verbal communication was recorded using a GoPro Hero 8 camera and an Ejeas Fbim wireless intercom system. A Wilcoxon signed-rank test was used to examine differences between referees’ ratings on two dimensions. The Mann-Whitney U test was employed to test the significance of differences in the mean scores of referees between groups divided by experience. The referees, in both dimensions (building positive climate and responsiveness to the players’ needs), scored on a 7-point scale, were rated at an average level of 3.22 (SD = 1.65) and 4.39 (SD = 1.67), respectively, with the responsiveness dimension rating being statistically significantly higher than the positive climate rating. The results showed that referee experience was not a determinant of the rating of the quality of referee–players’ interactions in both dimensions. From these studies, it was concluded that there is a need to complement the existing training programs for referees with the contents from the field of pedagogy and developmental psychology. This will help them build a positive climate during the game and show how to respond to children’s health, cognitive, emotional, and social needs. Furthermore, developing a referee’s pedagogical skills can improve their relationship with players, which can ultimately translate into a greater sense of job satisfaction. The formulated practical implications can also be transposed to other team sports.

Assessing the impacts of climate change to financial stability: evidence from China

Purpose Climate change not only causes serious economic losses but also influences financial stability. The related research is still at the initial stage. This paper aims to examine and explore the impact of climate change on financial stability in China. Design/methodology/approach This paper first uses vector autoregression model to study the impact of climate change to financial stability and applies NARDL model to assess the nonlinear asymmetric effect of climate change on China’s financial stability using monthly data from 2002 to 2018. Findings The results show that both positive and negative climate shocks do harm to financial stability. In the short term, the effect of positive climate shocks on financial stability is greater than the negative climate shocks in the current period, but less in the lag period. In the long term, negative climate shocks bring larger adjustments to financial stability relative to positive climate shocks. Moreover, compared with the short-term effect, climate change is more destructive to financial stability in the long run. Originality/value The paper provides a quantitative reference for assessing the nexus between climate change and financial stability from a nonlinear and asymmetric perspective, which is beneficial for understanding climate-related financial risks.

Lowland plant migrations into alpine ecosystems amplify soil carbon loss under climate warming

Climate warming is releasing carbon from soils around the world1–3, constituting a positive climate feedback. Warming is also causing species to expand their ranges into new ecosystems4–9. Yet, in most ecosystems, whether range expanding species will amplify or buffer expected soil carbon loss is unknown10. Here we used alpine grasslands as a model system to determine whether the establishment of herbaceous lowland plants in alpine ecosystems influences short–term soil carbon storage under warming. We found that warming (< 1 year) led to negligible alpine soil carbon loss, but its effects became significant and 52% ± 31% (mean ± 95% CIs) larger after lowland plants were introduced at low density into the ecosystem. We present evidence that soil carbon loss likely occurred via lowland plants increasing rates of root exudation, soil microbial respiration and CO2 release. Our findings suggest that warming–induced range expansions of herbaceous plants may yield a rapid positive climate feedback in this system, and that plant range expansions among herbaceous communities may be an overlooked mediator of warming effects on carbon dynamics.

Deglaciation-enhanced mantle CO2 fluxes at Yellowstone imply positive climate feedback

The generation of mantle melts in response to decompression by glacial unloading has been linked to enhanced volcanic activity and volatile release in Iceland and in global eruptive records. However, it is unclear whether this process is also important in magmatically-active systems that do not show evidence of enhanced eruption rates. For example, the deglaciation of the Yellowstone ice cap did not observably enhance volcanism, yet Yellowstone may still have released large volumes of CO2 to the surface due to the crystallization of melts at depth. Here we develop models to simulate mantle melt production and volatile release associated with the deglaciation of Yellowstone and Iceland. In agreement with previous work, we find mantle melt production in Iceland is enhanced 33-fold during deglaciation, generating an additional 3728 km3 of melt and releasing an additional 31–51 Gt of CO2. Beneath Yellowstone, we find mantle melt production is comparably enhanced 19-fold during deglaciation, generating an additional 815 km3 of melt, though thicker lithosphere may prevent the transport of this melt to the surface. These melts segregate an additional 135–230 Gt of CO2 from the mantle, representing a ~23–39% increase of the global volcanic CO2 flux (if degassed during deglaciation). Our results suggest deglaciation-enhanced mantle melting is important in continental settings with partially molten mantle (potentially Greenland and West Antarctica) and may result in positive feedbacks between deglaciation and climate warming.
