Group Polarization

Group Polarization

Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Design Example

Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

Upsampling

Upsampling

Managing signal sampling rates is essential in digital signal processing to maintain signal integrity. A decimated signal, characterized by a reduced frequency range due to its lower sampling rate, can be upsampled by inserting zeros between each sample. This upsampling process expands the original spectrum and introduces repeated spectral replicas at intervals dictated by the new Nyquist frequency. To refine this zero-inserted sequence, it is passed through a lowpass filter with a cutoff...

Properties of the z-Transform I

Properties of the z-Transform I

The z-transform is a fundamental tool in digital signal processing, enabling the analysis of discrete-time systems through its various properties. It is an invaluable tool for analyzing discrete-time systems, offering a range of properties that simplify complex signal manipulations. One fundamental property is linearity. For any two discrete-time signals, the z-transform of their linear combination equals the same linear combination of their individual z-transforms. This property is essential...

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Passive Filters

Passive Filters

Passive filters are utilized to shape the frequency spectrum of signals across a diverse array of applications. These filters, using only passive elements like resistors (R), inductors (L), and capacitors (C), are capable of selectively allowing or blocking certain frequency ranges without the need for external power sources.
Low-Pass Filters
Low-pass filters are designed to transmit signals with frequencies lower than the cutoff frequency, ωc, and attenuate those above it. The cutoff...

Summary

Bluesky, a decentralized social network, shares network structures similar to established platforms. While news sharing shows no political bias, the Israel-Palestine conflict reveals distinct, polarized user clusters.

Area of Science:

Social Media Analysis
Network Science
Computational Social Science

Background:

Bluesky is an emerging decentralized social media platform offering novel features and data access.
Understanding the network dynamics of new platforms is crucial for social science research.
This study characterizes the interaction network of Bluesky users.

Purpose of the Study:

To analyze the political leaning, polarization, network structure, and algorithmic curation of Bluesky users.
To investigate user engagement with custom-created algorithmic feeds.
To examine the political leaning of shared news sources and issue-based divergence on the platform.

Main Methods:

Analysis of a dataset comprising five million Bluesky users from February 2023 to May 2024.
Examination of network layers including replies, likes, reposts, and follows.
Analysis of shared hyperlinks and user opinions on the Israel-Palestine conflict.

Main Results:

Bluesky's network exhibits heavy-tailed distributions, high clustering, and short connection paths, mirroring larger social networks.
User adoption of custom-created algorithmic feeds is limited.
No political polarization was found in shared news sources; predominantly left-center sources were shared.
Significant issue-based divergence emerged regarding the Israel-Palestine conflict, forming two distinct homophilic clusters (pro-Palestinian and pro-Israeli), with pro-Palestinian voices being more numerous.

Conclusions:

Bluesky's network structure is comparable to existing large social media platforms despite its novel features.
The platform presents significant research opportunities for social, network, and political scientists.
While politically neutral in news sharing, Bluesky exhibits issue-based polarization.
