01:41Social Traps
26.2K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

01:27Traveling Waves: Lossless Lines
407
The provided content explores the behavior of traveling waves on single-phase lossless transmission lines. It begins with a single-phase two-wire lossless transmission line of length Δx, characterized by a loop inductance LH/m and a line-to-line capacitance C F/m. These parameters result in a series inductance LΔx and a shunt capacitance CΔx.

01:04Travelling Waves
6.5K
A wave is a disturbance that propagates from its source, repeating itself periodically, and is typically associated with simple harmonic motion. Mechanical waves are governed by Newton's laws and require a medium to travel. A medium is a substance in which a mechanical wave propagates, and the medium produces an elastic restoring force when it is deformed.
Water waves, sound waves, and seismic waves are some examples of mechanical waves. For water waves, the wave propagation medium is...

02:12Short-distance Transport of Resources
17.2K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:38Cognitive Dissonance
36.7K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

02:20Routes of Persuasion
68.3K
Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Resumen
Los viajes académicos tienen un impacto significativo en el medio ambiente. La comunidad científica debe adoptar herramientas en línea y reducir los eventos presenciales para reducir su huella de carbono.
Área de la Ciencia:
- Ciencias del medio ambiente
- Ecología
- Estudios de sostenibilidad
Sus antecedentes:
- Los viajes académicos, incluidas las conferencias y seminarios científicos, contribuyen sustancialmente a las emisiones mundiales de carbono.
- La pandemia de COVID-19 aceleró la adopción de tecnologías digitales para la comunicación académica y la colaboración.
Objetivo del estudio:
- Analizar el impacto ambiental de los viajes académicos.
- Abogar por un cambio sostenible en las prácticas de la comunidad científica después de la pandemia.
Principales métodos:
- Revisión de la literatura existente sobre las huellas de carbono de los viajes académicos.
- Análisis del impacto de las tecnologías de eventos en línea inducidas por la pandemia.
Principales resultados:
- Los viajes académicos representan una fuente importante de emisiones de gases de efecto invernadero.
- Las plataformas en línea ofrecen una alternativa viable para difundir información científica y fomentar la colaboración.
- Un enfoque híbrido que equilibre eventos presenciales y virtuales es factible.
Conclusiones:
- La comunidad científica debe integrar prácticas sostenibles para mitigar el impacto ambiental.
- El aprovechamiento de las tecnologías digitales puede reducir significativamente la huella de carbono de las actividades académicas.
- Es necesario un cambio permanente hacia una menor dependencia de los viajes académicos para la sostenibilidad ambiental.
