Biodiversity and Human Values

17.2K
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Professional Values

11.0K
Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

Critical Values01:31

Critical Values

10.4K
A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance level) for a given population parameter. The critical value provides demarcation that separates the sample statistics that are likely to occur from the ones that are unlikely to occur based on the given probability distribution and the population parameter to be estimated. The critical value for normal distribution is obtained from the z...

Population Growth

28.8K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

What is Population Genetics?

65.0K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Variation: Normal Distribution, Range, and Standard Deviation

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Area of Science:

  • Radiology
  • Urology
  • Medical Imaging

Background:

  • Accurate assessment of bladder wall thickness (BWT) on computed tomography (CT) is essential for diagnosing various bladder pathologies.
  • Establishing normal reference ranges for BWT is critical for differentiating disease from normal variation.

Purpose of the Study:

  • To determine normal bladder wall thickness (BWT) on CT in patients without bladder disease.
  • To establish reference BWT values correlated with bladder volume.

Main Methods:

  • Retrospective analysis of 419 patients with normal abdominal/pelvic CT scans.
  • Bladder wall thickness and volume (ellipsoid formula and automated technique) were measured.
  • Linear regression models were used to assess the correlation between BWT and factors including bladder volume, age, and gender.

Main Results:

  • Bladder wall thickness was significantly associated with bladder volume (p < 0.001).
  • Age and gender showed negligible contribution to BWT in the final model.
  • A parsimonious model demonstrated a strong correlation between BWT and bladder volume (R² = 0.52).

Conclusions:

  • Bladder wall thickness on CT is primarily correlated with bladder volume.
  • This study provides reference BWT values on CT, utilizing both ellipsoid and automated volume measurements.
