Frustration and Conflict: Approach-Approach, Approach-Avoidance01:20

Frustration and Conflict: Approach-Approach, Approach-Avoidance

532
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Actuarial Approach01:20

Actuarial Approach

308
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Information Processing Approach01:30

Information Processing Approach

569
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

The Nativist Approach01:21

The Nativist Approach

449
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Kaplan-Meier Approach01:24

Kaplan-Meier Approach

617
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Horney's Sociocultural Approach01:27

Horney's Sociocultural Approach

1.1K
Karen Horney's psychoanalytic theories emphasize the potential for self-realization and the importance of addressing social and cultural, rather than biological, factors in personality development. She challenged traditional Freudian views, particularly Freud's concept of "penis envy," which she argued stemmed from cultural influences rather than inherent biological differences. Horney believed that any sense of inferiority in women was a result of societal conditioning, such as...

Area of Science:

  • Surgical Innovation
  • Minimally Invasive Surgery
  • Gastrointestinal Surgery

Background:

  • Laparoscopic splenectomy (LS) is a minimally invasive surgical technique.
  • Standard LS approaches may present challenges in visualizing specific anatomical regions.

Purpose of the Study:

  • To introduce and evaluate a novel laparoscopic splenectomy (LS) technique.
  • To assess the safety and efficacy of this new approach.

Main Methods:

  • The study involved 16 patients undergoing LS under general anesthesia with carbon dioxide pneumoperitoneum.
  • Key steps included omental incision, pancreatic tail exposure, splenic pedicle retraction, and ultrasonic dissection of hilar vessels.
  • The spleen was retrieved in a bag after transection of associated ligaments.

Main Results:

  • Fifteen of sixteen patients successfully underwent the procedure between March 2015 and January 2016.
  • One patient required conversion to laparotomy.
  • No major complications like intra-abdominal hemorrhage or infection were observed; minor complications included subcutaneous emphysema and wound infection.

Conclusions:

  • The described laparoscopic splenectomy method, utilizing active exposure dorsal to the pancreatic tail, is presented as a safe and straightforward technique.
  • This approach facilitates complete visualization of the splenic hilum.
