The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Lazarus's Cognitive Appraisal Theory

2.0K
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Characteristics of Practical Op Amps

881
A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

Theoretical Foundations of Nursing Practice

18.0K
Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

Equivalent Circuits for Practical Transformers

1.4K
The practical equivalent circuits of single-phase two-winding transformers exhibit significant deviations from their idealized versions due to the inherent properties of winding resistance and finite core permeability. These properties result in real and reactive power losses, affecting the transformer's performance. Understanding these deviations is crucial for designing more efficient transformers.
In a practical transformer, each winding exhibits resistance and leakage reactance. The...

    Area of Science:

    • Synthetic biology
    • Technology appraisal
    • Bioethics

    Background:

    • Synthetic biology presents unique challenges for ethical technology appraisal.
    • Traditional methods like cost-benefit analysis (CBA) face difficulties in governing rapidly evolving technologies.
    • The debate around precaution in innovation often reveals polarized political viewpoints.

    Purpose of the Study:

    • To critically review methods for ethically robust technology appraisal in synthetic biology regulation.
    • To assess the utility of cost-benefit analysis (CBA) in guiding decisions on technological pathways.
    • To explore the potential of the precautionary principle and alternative appraisal methods like multicriteria mapping (MCM).

    Main Methods:

    • Critical review of existing literature on technology appraisal and synthetic biology governance.
    • Analysis of the limitations of cost-benefit analysis (CBA) in complex innovation contexts.
    • Exploration of multicriteria mapping (MCM) as a practical appraisal method for emerging technologies.

    Main Results:

    • Cost-benefit analysis (CBA) presents significant, often overlooked, challenges in the context of synthetic biology.
    • The precautionary principle, though debated, is crucial for addressing uncertainties in emerging technologies.
    • Multicriteria mapping (MCM) offers a viable alternative for appraising divergent perspectives on new technologies.

    Conclusions:

    • Existing appraisal methods, including CBA, are insufficient for the ethical governance of synthetic biology.
    • The precautionary principle and methods like MCM are essential for more rigorous and practical decision-making.
    • Adopting diverse appraisal techniques is vital to navigate the complexities and societal implications of synthetic biology innovation.
