Schemas

12.5K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Collisions in Multiple Dimensions: Problem Solving

5.7K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Collisions in Multiple Dimensions: Introduction

7.3K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

Crossing Over

7.3K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...

Crossing Over

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

    Summary
    This summary is machine-generated.

    Despite decades of cultural safety guidelines, Māori nurses face challenges. Enhanced investment in Māori nursing and cultural competency is crucial for effective whanaungatanga care models in healthcare.

    Area of Science:

    • Nursing Education
    • Cultural Safety in Healthcare
    • Indigenous Health

    Background:

    • Cultural safety guidelines (Kawa Whakaruruhau) were established in 1992 by Irihapeti Ramsden.
    • The Nursing Council has revised these guidelines multiple times, with the latest revision in 2011.
    • The Te Puna Hauora Kaupapa Nursing Service at Tauranga Hospital has operated for over 18 years.

    Purpose of the Study:

    • To highlight the experiences of Māori nurses.
    • To assess the adoption of bicultural nursing services nationwide.
    • To advocate for increased investment in Māori nursing.

    Main Methods:

    • Qualitative exploration of Māori nurses' experiences.
    • Analysis of the implementation of cultural safety guidelines.
    • Review of bicultural nursing service adoption across the country.

    Main Results:

    • Māori nurses report ongoing challenges.
    • The adoption of truly bicultural nursing services remains limited nationally.
    • Significant investment is still required in Māori nursing.

    Conclusions:

    • There is a persistent need for greater investment in Māori nursing.
    • Developing cultural competencies and awareness is essential for healthcare professionals.
    • Implementing whanaungatanga models of care requires enhanced cultural capacity within the healthcare system.
