Barriers to Effective Communication II01:21

Barriers to Effective Communication II

3.7K
The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Contact-dependent Signaling01:19

Contact-dependent Signaling

44.9K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
Gap Junctions
In animal cells, gap junctions are formed...

Barriers to Effective Communication I

9.4K
A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Gene Flow02:39

Gene Flow

35.5K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Bacterial Signaling01:30

Bacterial Signaling

33.7K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Gene Regulation in Microbial Communities: Quorum Sensing01:28

Gene Regulation in Microbial Communities: Quorum Sensing

86
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Area of Science:

  • Science Communication
  • Sociology of Science

Background:

  • Science communication fellowship programs serve as crucial entry points for scientists and communicators seeking skill development and career advancement.
  • These programs have the potential to either mitigate or reinforce existing societal inequities.

Purpose of the Study:

  • To investigate the types of capital provided by US-based science communication fellowship programs.
  • To identify the rules and norms influencing access to these programs.

Main Methods:

  • Qualitative study involving interviews with 25 directors of 23 US-based science communication fellowship programs.

Main Results:

  • Fellowship programs provide significant cultural and social capital through experiential learning and mentorship.
  • Access to these programs appears to be influenced by factors such as infrastructure, literacy, and community acceptance.

Conclusions:

  • Current practices may perpetuate the status quo and social inequity.
  • A call for reflexivity and actionable transformation within science communication fellowship programs is necessary to promote equity.
