Self-Evaluation: Self-Enhancement and Self-Verification03:00

Self-Evaluation: Self-Enhancement and Self-Verification

5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Nursing Evaluation

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

322
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Dysrhythmias V: Evaluating Dysrhythmias

380
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Social Foundations of Self III: Self-Evaluation

198
Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often...

Evaluating Limits by Direct Substitution01:29

Evaluating Limits by Direct Substitution

179
In the analysis of functions that represent continuous physical phenomena, it is often necessary to determine the output value as the input approaches a specific point. When a combination of algebraic terms defines the function and exhibits no discontinuities or abrupt changes near the point of interest, the limit of the function can be evaluated directly. This process, known as direct substitution, involves replacing the variable in the expression with the value it approaches.Direct...

Area of Science:

  • Medical Parasitology
  • Maternal-Fetal Medicine
  • Infectious Diseases

Background:

  • Toxoplasmosis during pregnancy can lead to congenital toxoplasmosis.
  • Evaluating the presence of Toxoplasma gondii in placental tissues is crucial for understanding fetal transmission risks.

Purpose of the Study:

  • To determine the prevalence of the Toxoplasma gondii B1 gene in placental tissues of pregnant women experiencing acute toxoplasmosis.

Main Methods:

  • A cross-sectional study involving serum testing for Toxoplasma gondii immunoglobulin G (IgG) antibodies using ELISA.
  • Polymerase chain reaction (PCR) was employed to detect the T. gondii B1 gene in serum and placental tissues.
  • Umbilical cord and neonatal blood were tested for immunoglobulin M (IgM) antibodies.

Main Results:

  • Toxoplasma gondii IgG antibodies were found in 25.6% of 653 pregnant women.
  • The T. gondii B1 gene was detected in 21.6% of IgG-positive women.
  • The B1 gene was present in 86.7% of evaluated placental tissues from infected mothers.

Conclusions:

  • The Toxoplasma gondii B1 gene is frequently detected in placental tissues during acute maternal toxoplasmosis.
  • While the B1 gene was found in placental tissues, no IgM antibodies were detected in neonates, suggesting varied transmission outcomes.
