Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

The Behavioral Perspective on Personality

810
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

Criticisms of the Evolutionary Perspective

348
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Social Cognitive Perspective on Personality

1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Kinematic Equations for Rotation01:30

Kinematic Equations for Rotation

785
In mechanics, when one observes a rigid body in rotational motion with constant angular acceleration, it is possible to establish equations for its rotational kinematics. This process resembles how linear kinematics are dealt with in simpler motion studies.
For instance, imagine a point A on a rigid body engaged in circular motion. The translational velocity of this particular point can be calculated by taking the time derivatives of the displacement equation, which essentially measures the...

Changes in Skin Color: Clinical Perspectives

3.4K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Summary

Rotational atherectomy (RA) procedures in Australia tripled from 2007 to 2017. This increase occurred alongside stable percutaneous coronary intervention (PCI) rates and a decline in coronary artery bypass graft (CABG) surgeries.

Area of Science:

  • Cardiovascular Interventions
  • Health Services Research
  • Interventional Cardiology

Background:

  • Rotational atherectomy (RA) has been a PCI technique for three decades.
  • Technological advancements prompt an examination of RA utilization trends.
  • This study analyzes RA rates relative to PCI and CABG in Australia over ten years.

Purpose of the Study:

  • To assess trends in Rotational Atherectomy (RA) utilization.
  • To compare RA rates with Percutaneous Coronary Intervention (PCI) and Coronary Artery Bypass Graft (CABG) rates.
  • To identify geographical variations in RA usage within Australia.

Main Methods:

  • Retrospective analysis of national data from 2007 to 2017.
  • Utilized Australian Government Department of Human Services Medicare item data.
  • Examined rates of RA, PCI, and CABG by Australian state.

Main Results:

  • RA procedures increased from 149 in 2007 to 452 in 2017.
  • RA constituted 0.67% of PCI in 2007, rising to 1.48% in 2018.
  • New South Wales showed a 441% increase in RA procedures; PCI rates rose, while CABG rates declined.

Conclusions:

  • RA utilization in Australia tripled between 2007 and 2017.
  • This trend persisted despite stable PCI rates and decreasing CABG rates.
  • Clinical factors likely explain the observed increase in RA usage.
