The Representativeness Heuristic02:13

The Representativeness Heuristic

16.8K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

National Nursing Organizations I

3.1K
Nursing organizations assume a significant role in consistently developing the nursing profession through education, research studies, establishing practice standards, and reforming health policies. Typically, nursing organizations operate at the regional, national, and international levels. For example, the International Council of Nurses (ICN) represents more than 28 million nurses worldwide. In contrast, the American Nurses Association (ANA) is a membership organization representing nurses...

National Nursing Organizations II

2.1K
Nursing organizations play a vital role in representing nurses working in specialized clinical settings, such as the American Association of Critical-Care Nurses (AACN).
The AACN emphasizes a healthy work environment through six standards to achieve an optimal patient outcome. The standards are appropriate staffing, meaningful recognition, collaboration, authentic leadership, effective communication, and decision-making. In addition, AACN provides certification programs, webinars, journals, and...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

10.9K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

107.4K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Measurement: Standard Units03:38

Measurement: Standard Units

81.3K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Summary

Cataract surgery in the UK National Health Service (NHS) achieved excellent refractive outcomes, meeting Royal College of Ophthalmologists targets. However, current biometry practices may limit achieving higher benchmark standards for all NHS units.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Public Health

Background:

  • Assessing refractive outcomes of National Health Service (NHS) cataract surgery.
  • Evaluating performance against established benchmark standards.

Purpose of the Study:

  • To report refractive outcomes from a decade of NHS cataract surgery.
  • To determine if outcomes meet suggested benchmark standards.

Main Methods:

  • Prospective data collection of 11,083 cataract surgeries (Nov 2006-Dec 2016).
  • Inclusion of 8,943 eyes with uncomplicated 'in the bag' non-toric intraocular lens implantation.
  • Exclusion of patients with prior laser refractive procedures or suboptimal postoperative acuity.

Main Results:

  • Mean refractive error difference: -0.07 D (SD 0.67).
  • Mean absolute error: 0.50 D.
  • 88.76% of eyes within 1 D and 62.36% within 0.50 D of target refraction.

Conclusions:

  • Refractive outcomes align with Royal College of Ophthalmologists and European guidelines.
  • Current biometry practices may hinder achieving higher benchmark standards in all NHS units.
