In an era of pervasive misinformation, equipping citizens to counter its spread is increasingly critical. This study examines news authentication—individuals’ proactive verification news—as a key indicator resilience misinformation. Guided by the theory planned behavior and model, we examine how individual characteristics structural contexts interact influence authentication. To do so, adopt multilevel comparative approach, analyzing authentication in three distinct societies: Hong Kong,...
In this paper, we study the matched filter based spectrum sensing in a more reasonable cognitive radio (CR) scenario when primary user (PU) could possibly work on than one transmit power levels. Besides traditional target where secondary (SU) should decide presence of PU, an additionally new here be also recognizing levels which achieves "cognition" for CR. We derive closed form solutions decision regions and several performance metrics, from some interesting phenomenons are observed related...

This study reconstructs paleoclimate paleoecosystem Santanghu Basin by analyzing palynological assemblages clay minerals from Xishanyao Toutunhe formations. Two distinct were identified: <italic>Cyathidites-Deltoidospora-Osmundacidites-Cycadopites</italic>(CDOC) assemblage...
Emotionality is a well-established strategy for boosting audience engagement on social media. While fact-checking positioned to provide objective information, posts media often involve heightened emotionality. How much emotionality present and how influences public sentiment toward fact-checked targets remain largely understudied. Informed by psychological frameworks explicating message-level factors influencing sentiment, the study examines in 49,270 created 10 United States organizations...
ABSTRACT This study examines how government responses to citizen inquiries on governmental social media enhance policy communication campaigns for observers. Drawing upon theories of masspersonal and artificial intelligence (AI)‐mediated communication, it investigates the effects replying agents, inquiry tones, institutional trust observers’ perceptions campaigner, campaign message, communicated policy. A pre‐registered four (replying agents: AI‐powered bot editor, human AI–human tandem...
In this paper, we investigate the matched filter based spectrum sensing in a more reasonable cognitive radio (CR) scenario when primary user (PU) has than one transmit power levels, as regulated most standards, i.e., IEEE 802.11 Series, GSM, LTE, LTE-A, etc. This new multiple (MPTP) is specialized by two different targets: detecting presence of PU and identifying level. Compared to traditional binary where only checked, SU may attain information about network (making CR "intelligent") design...
Social media is widely used by journalists for sourcing and verification. While social may either serve as supplementary to existing sources or replace traditional channels, it nevertheless poses challenges the news professionalism. The present study examines relationship between journalists' use of other channels It also how attitudes towards affect An online survey (n = 255) in local organizations Hong Kong—a society with a high penetration rate highly competitive market—revealed that rely...
This paper settles the sample complexity of single-parameter revenue maximization by showing matching upper and lower bounds, up to a poly-logarithmic factor, for all families value distributions that have been considered in literature. The bounds are unified under novel framework, which builds on strong monotonicity Devanur, Huang, Psomas (STOC 2016), an information theoretic argument. is fundamentally different from previous approaches rely either constructing $\epsilon$-net mechanism...
Abstract Exposure to presumably uncivil content is neither a necessary nor sufficient condition for perceptions of incivility and thus could lead differential political consequences. To examine the emergence consequences perceived in disagreement comments, present study reports on two population-based online survey experiments Hong Kong (N1 = 1,207, N2 611). The results indicate that individuals perceive higher degree comments directed in-group members than those out-group members,...
Abstract In addition to canonical political actions, consumerism, i.e. using market purchases express and societal concerns, is becoming a new form of participation, it varies significantly among societies. Two society‐level distinctions would account for such variations: the level freedom economic development. Using data from 2004 International Social Survey Program, multilevel models estimate effects both individual structural factors on individuals’ boycotting certain products, across 21...
Data(-driven) journalism has triggered debates about whether this innovative storytelling and investigative approach, using data analytical computational methods, better serves the public. Applying concept of articulation, wherein an array terms are juxtaposed expressed together, paper examines how term "data-driven journalism" is represented on social media. Focusing Twittersphere as research context, employed Twitter search application programming interface (API) to harvest all available...
Psychological reactance theory proposes that people resist persuasive messages when they feel their freedom is being threatened. While most studies have focused on a single issue and the role of message features has received modest amount attention, present study synthesizes research sociolinguistic public opinion to investigate how affected by restoration, language variety (i.e., standard versus colloquial forms language), issues: enduring (binge-drinking prevention), emerging (organ...
In this research, the microstructure evolution in machined subsurface is numerically simulated through a developed multi-physics model applied to H13 hot work die steel. The based on dislocation density utilized predict change of grain size finite element analysis by varying cutting parameters. spite conditions, top-most surface around 330 nm, and machining-affected depth with refined varies range 25–45 μm. addition, appeared periodical fluctuation wavy configuration induced generated...
Memristive devices are an emerging new type of operating at the scale a few or even single atoms. They currently used as storage elements and investigated for performing in-memory neuromorphic computing. Amongst these devices, Ag/amorphous-SiOx/Pt memristors among most studied systems, with electrically induced filament growth dynamics being thoroughly both theoretically experimentally. In this paper, we report observation novel feature in devices: The appearance photoluminescent centers...
The Jenkyns Event (~183 Ma) represents an exceptional warming period in the Jurassic, which is characterized by intense environmental and climate perturbation. eruption of Karoo‐Ferrar Large Igneous Province (K‐F LIP) triggered pronounced carbon isotope negative excursion (N‐CIE) exogenic reservoirs, global widespread organic burial extensive ocean anoxia. However, synchronic coupling relationship between release, volcanic activity, weathering induced K‐F LIP during this remains poorly...
