Common Ion Effect

Common Ion Effect

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

The Uncertainty Principle

The Uncertainty Principle

Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Long-term Depression

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Hardy-Weinberg Principle

Hardy-Weinberg Principle

Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

The Pauli Exclusion Principle

The Pauli Exclusion Principle

The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

Summary

Concerns about short-term medical missions (STMMs) have led to guidelines. These guidelines, primarily from the Global North, emphasize host partnerships and ethical practices, but need host country input and enforcement strategies.

Medical Ethics
Public Health Policy

Background:

Growing concerns exist regarding the effectiveness and value of short-term volunteer trips aimed at health improvement in Global South communities.
Multiple organizations and individuals have developed guidelines to mitigate potential harms and maximize benefits of these volunteer efforts.

Purpose of the Study:

To analyze existing guidelines for short-term medical missions (STMMs) based on literature up to early 2017.
To examine the authorship, intended audiences, scope, and implementation focus of these guidelines.
To compare guideline content with the perspectives of host communities and staff.

Main Methods:

A scoping review of the literature was conducted to identify and analyze 27 guidelines related to STMMs.
Guidelines were assessed for authorship, target audience, addressed aspects of STMMs, and attention to implementation.
Findings were contextualized with studies on host country staff perspectives.

Main Results:

Existing guidelines are predominantly authored by and directed towards Global North educators and practitioners.
There is consensus on core principles: host partnerships, preparation, needs assessment, sustainability, and ethical standards.
Host country staff agree with key principles but emphasize mutual learning and respect.

Conclusions:

Guidelines require integration of host country research and policy directives, which are currently lacking.
A comprehensive strategy is needed to ensure adherence to best practices, addressing limited regulation and strong incentives for non-compliance.
Future guidelines should incorporate host country perspectives more robustly and address implementation challenges.
