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...

The Scientific Method

67.6K
Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.

The Scientific Method

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Nursing Evaluation

4.4K
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

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...

Summary

Catching broiler chickens by the abdomen in an upright position (UPRIGHT) reduced wing fractures and improved stocking density compared to the two-leg method (LEGS). This broiler catching technique may enhance animal welfare and efficiency.

Area of Science:

  • Animal Welfare Science
  • Poultry Husbandry
  • Pre-slaughter Handling

Background:

  • Manual catching of broiler chickens is a critical pre-slaughter step.
  • Current handling methods can negatively impact animal welfare.
  • Variations in catching techniques may influence broiler health and processing efficiency.

Purpose of the Study:

  • To compare the welfare outcomes and efficiency of two broiler catching methods: two-leg inverted (LEGS) versus abdomen upright (UPRIGHT).
  • To evaluate the impact of catching method on fracture incidence, stocking density, and handling time.

Main Methods:

  • A pilot study comparing manual catching of broiler chickens using the LEGS method versus the UPRIGHT method.
  • Assessment of wing and leg fractures, animal density in transport drawers, birds on their back, dead-on-arrival broilers, and time to fill transport modules.

Main Results:

  • The UPRIGHT method resulted in significantly shorter mean crating times (p = 0.007).
  • A trend towards more wing fractures was observed with the LEGS method (p = 0.06).
  • The UPRIGHT method led to lower and more consistent animal density in drawers (p = 0.022).

Conclusions:

  • Catching broiler chickens under the abdomen in an upright position appears to be a more welfare-friendly method.
  • The UPRIGHT technique may reduce wing fractures and improve stocking density consistency.
  • This method has the potential to decrease loading times in broiler processing operations.
