Summary
Bike coalitions are vital for creating bike-friendly communities, but often lack resources. Addressing financial and personnel barriers can enhance their capacity for advocacy and programming.
Area of Science:
- Public Health
- Urban Planning
- Community Development
Background:
- Bicycle coalitions are key partners in promoting bike-friendly communities through infrastructure advocacy, cycling encouragement, and safety education.
- Their operational functioning and capacity remain underexplored despite their diverse roles.
Purpose of the Study:
- To examine the capacity, strengths, and weaknesses of bicycle coalitions.
- To identify factors influencing their effectiveness in community engagement and advocacy.
Main Methods:
- Online surveys were distributed to bicycle coalitions/advocacy groups in English-speaking countries.
- The survey collected data on coalition demographics, leadership, communication, priorities, barriers, and partnerships.
Main Results:
- 56 coalitions participated, mostly non-profits. Leadership skills included fundraising, event planning, urban planning, and policy expertise.
- Top priorities were education and encouragement; activities focused on cyclist safety and infrastructure/policy advocacy.
- Significant barriers included lack of financial resources (81.8%) and personnel (56.8%). Grant availability was a key motivator for improvement (86.4%).
Conclusions:
- Understanding bicycle coalition capacity is crucial for developing targeted interventions and resources.
- This knowledge can inform the creation of skill-building programs, effective toolkits, and collaborations to combat physical inactivity.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

01:16Efficiency of The Carnot Cycle
3.8K
The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...

01:27Otto and Diesel Cycle
3.9K
An Otto engine is a four-stroke engine that uses a mixture of gasoline and air as the working fuel. The fuel is injected into the cylinder, and the piston is moved completely down so that the cylinder is at maximum volume. By moving the piston up, adiabatic compression takes place. The spark plug ignites the gasoline-air mixture, and the burning fuel adds heat to the system at a constant volume. The heated mixture expands adiabatically and gets further cooled by exhausting heat, and this cyclic...

01:17Factors Affecting Activity Coefficient
1.7K
The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...

01:46The Calvin Benson Cycle
6.4K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

01:37Social Loafing
39.8K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...
