The use of eye tracking glasses in basketball shooting : a systematic review

Sports performance is related to cognitive processes that precede the motor task to be developed. In this way, the coupling between visual information and motor behavior has a major importance in filtering the visual information, necessary to the accomplishment of the motor task to be executed, ignoring ‘accessory’ stimuli. In this field, this essay has the goal of achieving a systematic review about past studies in the context of basketball shooting. We bring to you some evidence that support the applicability and efficiency of Eye Tracking Glasses systems in the analysis of visual attention in basketball shooting, emphasizing the concept of Quiet Eye, interconnected with anxiety and occlusion of vision. The results of the studies demonstrate the importance of the use of Eye Tracking Glasses for the evaluation/intervention in the process of visual attention training related to efficiency in shooting.info:eu-repo/semantics/publishedVersio

Using Social Media for Business Communication: A Symbolic Interaction Perspective

It is important to understand the symbolic meaning of social media perceived by users in a particular communication context, as it may completely deviate from designers’ original intentions. In the exploratory case study of Moon Struck hotel in China, we investigate how customers interpret this hotel’s use of WeChat (the most dominate instant messaging tool in China) for business communication and how customers respond to messages received from WeChat in this context. Leveraging the symbolic interaction perspective, we report that customers’ interpretation towards the symbolic meaning of WeChat varies across personal and business communication contexts, and subsequently affects customers’ usage behaviour of WeChat. Drawing on in-depth interviews with 12 selected followers of the hotel’s WeChat account, as well as company executives at this hotel, we identify the key findings and discuss the theoretical implications and practical recommendations

Geoscience Letters, 8(1), (2021): 29, https://doi.org/10.1186/s40562-021-00199-3.Seasonal variability of the ocean bottom pressure (OBP) in the world oceans is investigated using 15 years of GRACE observations and a Pressure Coordinate Ocean Model (PCOM). In boreal winter, negative OBP anomalies appear in the northern North Pacific, subtropical South Pacific and north of 40 °S in the Indian Ocean, while OBP anomaly in the Southern Ocean is positive. The summer pattern is opposite to that in winter. The centers of positive (negative) OBP signals have a good coherence with the mass convergence/divergence due to Ekman transport, indicating the importance of wind forcing. The PCOM model reproduces the observed OBP quite well. Sensitivity experiments indicate that wind forcing dominates the regional OBP seasonal variations, while the contributions due to heat flux and freshwater flux are unimportant. Experiments with daily sea level pressure (SLP) forcing suggest that at high frequencies the non-static effect of SLP is not negligible.This research was supported by the National Key R&D Program of China (2018YFA0605702), Natural Science Foundation of China (Grant nos. 41522601, 41876002, 41876224)

How to Retain Consumers: A Trust-Commitment Model

Although studies on the determinants of consumers’ continuance intention in e-marketplaces have grown in recent years, the research is predominantly related to unidimensional trust and commitment. In this research, the authors focus on the distinct roles of different types of consumer trust and commitment on consumers’ continuance intention. Drawing upon organizational commitment and trust theories, we develop a continuance intention model that includes two types of trust and two types of commitments. We collected a sample of 287 online consumers to validate the theoretical model. Our data suggest that consumers’ trust and commitment positively affect their continuance intention. Our study also indicates that the psychological states underlying the commitments are different. Key findings and implications are discussed

Implication of Production Tax Credit on Economic Dispatch for Electricity Merchants with Storage and Wind Farms

The production tax credit (PTC) promotes wind energy development, reduces power generation costs, and can affect merchants\u27 joint economic dispatch, particularly for electricity merchants with both energy storage and wind farms. Two common PTC policies are studied – in the first policy, a wind farm receives PTC by selling wind generation to the market and its storage can be used to store energy from the wind generation and energy purchased from the grid but the energy released from the storage cannot receive PTC; in the second policy, the energy released from the storage can also qualify for PTC but purchasing energy from the grid is not allowed. We then employ dynamic programming to study merchants\u27 optimal decision-making while considering PTC and the physical characteristics of storage systems. We analytically show that the state of charge (SOC) range can be segmented into different regions by SOC reference points under two PTC policies. The merchant\u27s optimal action can be conveniently and uniquely determined based on the region within which the current SOC falls. Moreover, this study illustrates that PTC could substantially alter the optimal scheduling policy structures by affecting reference points and their relationships. The results showed that the frequencies for charging and discharging storage decisions decreased with an increase in PTC subsidy. Last, we confirm that, although the first policy allows merchants to buy electricity from the market, the second policy can bring more profits when the PTC is large at the current PTC rates. The findings can provide multistage decision-making guidance to electricity merchants in the wholesale power market
