Planning Interventions for Improving Physical Activity
Planning interventions such as action planning (AP) and coping planning (CP) have been recognized as influential strategies in promoting physical activity (PA), but mixed results of existing evidence have been observed. Researchers aim to perform a systematical meta-analysis to evaluate the efficacy of planning interventions for improving PA in the general population. The findings indicate that planning interventions significantly improved PA behavior, and, in some contexts, the effects performed better. Future research needs to be conducted to explore the underlying mechanisms of planning interventions and validate their effects more extensively.

Plural Nature(s): An Overview of Their Sociocultural Construction
The social construction of nature aims to emphasise that the concept of nature has multiple meanings that vary in different socio-cultural contexts. This underlines the multiple ways in which both structures and individuals understand, explain, and engage with nature and the environment. Consequently, nature and cultures/societies are not separate entities, but are intertwined in complex and interdependent relationships. Therefore, nature is the result of human perceptions and social practices. The way we interact with, perceive, interpret, and value nature is influenced by a given society’s history and sociocultural factors. This intimate relationship is closely linked to power–knowledge and influence relations. Those with more power can impose a particular vision of, and relationship with, nature, resulting in inequalities and potentially harmful relations that can explain the environmental degradation that the contemporary world faces globally, despite its expression in particular contexts, thus configuring plural natures.

Polarization (Politics)
Template:Globalize/US In politics, polarization (or polarisation) can refer to the divergence of political attitudes to ideological extremes. Almost all discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. When polarization occurs in a two-party system, like the United States , moderate voices often lose power and influence.

Police Use of Force Models
Recent calls for widespread police reform include re-examination of existing training and practice surrounding the use of force (UOF, e.g., verbal and non-verbal communication, physical tactics, firearms). Visual models representing police UOF decision-making are used for both police training and public communication. However, most models have not been empirically developed or assessed in either the applied police or vision science literatures, representing significant gaps in knowledge. Based on a critical appraisal of the visual features of common police UOF models, the current entry concludes with evidence-based recommendations for effective model design that accurately reflects the complexity and dynamism of police UOF decision-making in both police training and public communication contexts.

Policy Effects of Talent Housing in Shanghai
Housing has become pivotal in attracting and retaining talent in first-tier cities. Although numerous cities are actively promoting the provision of talent housing in China, little is known about the talent’s evaluations of talent housing policies or the effect on their urban settlement intention. Binary logistic regression was employed to analyse the factors significantly contributing to the settlement intentions of the talent. Talent housing was confirmed to alleviate the talent’s housing pressures and further increase their urban settlement intention. The local hukou was determined to be crucial in accelerating the willingness of talent to settle in Shanghai. However, housing affordability (including school district housing) may jeopardise such positive effects. It is crucial to provide more choices of talent housing and increase the coverage of good-quality educational resources. In the long run, more talent can be attracted and retained in the locality under a broader coverage of the talent housing scheme.

Policy Instruments for Renewable Energy Development in China
The impact of energy shortage and environmental pollution on the world economic development is increasingly prominent. On the 5th anniversary of the Paris Agreement, China declared its national goal of achieving “emission peak” by 2030 and “carbon neutrality” by 2060. In terms of China’s current energy consumption structure, fossil energy represented by coal is still the mainstay of current energy utilization. However, traditional fossil energy sources such as coal and oil are being replaced by renewable energy sources such as solar, wind, and nuclear energy. The Chinese government is aware that in order to achieve long-term economic development, it is necessary to properly deal with climate change, energy demand and environmental protection. The development of renewable energy provides an effective solution to these problems. The renewable energy industry needs policy instruments to support it in order to survive in the market in the early stages of development. However, subsidies do not last long. As the renewable energy industry develops, the support and subsidy mechanism will be phased out, and the energy industry will enter the commercialization stage. Finally, a policy system combining government guidance and market mechanism will form.
