Polarization in globalization business operation ?5 answersGlobalization impacts polarization in various aspects of business operations. Research shows that globalizing key commercial roles and R&D can lead to increased polarization. Additionally, the restructuring of economies in global cities due to globalization can cause social polarization, affecting employment structures and income levels. On the other hand, studies indicate that globalisation tends to decrease polarization in society and politics, with economic and political globalization measures showing negative relationships with polarization indicators. Furthermore, foreign technological convergence can be a source of wage polarization, particularly in the US labor market, due to business stealing and increased competition in global innovation races. Overall, the effects of globalization on polarization in business operations are multifaceted and can vary depending on the specific context.
Why polarization in a lcd changes the colors?5 answersThe polarization in an LCD changes the colors because it affects the way light is transmitted and reflected within the display. The use of different polarization orientations can control and tune the color of scattered light in resonant scattering by silicon nanodisks. In LCD projectors, the rotation of polarization orientations of the analyzers can change the operational modes of LCD panels and allow for the generation of two orthogonally polarized views for stereoscopic projection. Additionally, modifying the polarization state of light exiting an LCD display can improve contrast ratios and color saturation without sacrificing image quality. By reducing the select voltage to the LCD cell, the polarization state of the light exiting a dark selected pixel compensates for misalignment between the saturation voltage polarization axis of the display and the system polarization axis of the optics.
Why polarization is important in plasmas?4 answersPolarization is important in plasmas because it affects various aspects of plasma behavior and interactions. In gyrokinetic theory, the polarization effects are analyzed by using hybrid coordinates, which include the nonlinearity of polarization displacement. The generation and transport of fast electrons in laser-plasma interactions are influenced by the polarization of the laser pulse. Plasma polarization spectroscopy provides valuable information about high energy density plasmas, including the existence, directionality, and energy of particle beams. In the context of AdS/CFT holography, the polarization coefficients of a strongly-coupled plasma are related to the tidal deformation coefficients of a black brane. The polarization properties of gamma photons emitted from a plasma can be used to probe the plasma dynamics and its susceptibility to quantum electrodynamical processes.
How do like-minded sources on Facebook affect the polarization of users?5 answersSelective online exposure to information that affirms people's opinions or aligns with their interests can lead to the formation of echo chambers, which can contribute to polarization and radicalization. Social media platforms like Facebook facilitate the formation of echo chambers through homophily and depersonalization, which can be particularly harmful in the case of conspiracy beliefs. Echo chambers can lead to a stronger seclusion from society, encourage socially destructive actions, and curate fake news. Additionally, the use of incivility in Facebook posts has been found to increase online engagement, suggesting that like-minded sources that use incivility can contribute to polarization. However, the role of incivility in affecting affective polarization is limited, with party identification being a stronger predictor. Therefore, while like-minded sources on Facebook can contribute to polarization, other factors such as party identification also play a significant role.
Can polarization be used to detect nerves?4 answersPolarization can be used to detect nerves. Polarization-sensitive optical coherence tomography (PS-OCT) has been shown to visualize birefringent structures in both rat and human prostate specimens, which were confirmed to be nerves by histology or multiphoton microscopy. PS-OCT imaging of human prostatectomy specimens also revealed spatial variation in the amount of birefringent fibrous structures, consistent with anatomy. PS-OCT has also been used to visualize the orientation of nerves in the retinal nerve fiber layer (RNFL) and collagen fibers in peripapillary sclera in healthy volunteers. Additionally, the polarization of an optical image has been shown to be a potential way to make target detection and identification easier with higher accuracy. Therefore, polarization can be a useful tool for detecting nerves in various applications.
How does M1 and M2 polarization work?4 answersM1 and M2 polarization refers to the activation states of macrophages and microglia, which are important immune cells in the body. M1 macrophages and microglia are involved in pro-inflammatory responses, while M2 macrophages and microglia are involved in anti-inflammatory responses. The polarization of these cells can be influenced by various factors, such as the tumor microenvironment, nanocarriers, nuclear receptor PPARγ, phagocytosis, and NF-κB signaling pathways. The polarization states of macrophages and microglia can be induced by different stimuli. M1 polarization is typically induced by lipopolysaccharide (LPS) or interferon-gamma (IFN-γ), leading to the expression of pro-inflammatory cytokines. On the other hand, M2 polarization is induced by interleukin-4 (IL-4) or interleukin-13 (IL-13), promoting the resolution of inflammation and tissue repair. The polarization of macrophages and microglia is important for their functions in immune responses and tissue homeostasis.
