Abstract In this article, we introduce and showcase how social media can be used to implement experiments in public administration research. To do so, pre-registered a placebo-controlled field experiment implemented it on the platform Facebook. The purpose of was examine whether government funding nonprofit organizations has an effect charitable donations. Theories interaction between donations stipulate that either decreases (crowding-out), or increases (crowding-in) private test these...

Abstract Text annotation, the practice of labeling text following a predetermined scheme, is essential to qualitative public policy research. Despite its importance, annotating large data faces challenges high labor and time costs. Recent developments in language models (LLMs), specifically with generative pretrained transformers (GPTs), show potential approach that may alleviate burden manual annotation. In this report, we first introduce small sample pretest strategy for researchers decide...

The topological physics has sparked intensive investigations into lattices in photonic, acoustic, and mechanical systems, powering counterintuitive effects otherwise inaccessible with usual settings. Following the success of these endeavors classical wave dynamics, there been a growing interest establishing their counterparts diffusion. Here, we propose an additional real-space dimension diffusion, system eigenvalues are transformed from "imaginary" to "real." By judiciously tailoring...

What difference does “nonprofitness” make is a fundamental question for nonprofit research. Although being held as the basic assumption of contract failure theory, sector perceived by individuals remains an open multiple methodological problems. Here, we present evidence from three experiments further empirical exploration with improved research design. Our findings suggest general pattern stereotype: people perceive nonprofits warmer and slightly more competent than for-profits. More...

Abstract Leveraging a three‐state survey of 323 civil servants and 36 interviews, representing blue red states, this university‐government‐nonprofit collaborative research project aims to better understand how access use evidence in their decision‐making process. Our findings show that 54% respondents find evidence‐based practices (EBPs) useful making budget, policy, contracting decisions, with 68% anticipating future benefits from use. hypothetical funding choice experiment indicates prefer...

Naming a contagious disease, such as COVID-19, by the geographic locality where disease originates or starts, for example, Wuhan China, may stigmatize specific ethnic groups related to that locality, and stigmatizing behavior will further lead legitimized discrimination, prejudice, group conflicts. However, construction of social stigma relates closely identities, creating xenophobia through out-group members increase in-group solidarity, which can be taken political strategy government...

Experimental evidence suggests that citizens' judgments of service quality often rely on prior beliefs about providers' characteristics, such as racial stereotypes. Such a biased judgment process prevents the public from understanding performance information accurately and choosing high-quality providers. To address this, we studied relation between evaluation mode proposed presenting jointly (joint evaluation) rather than separately (separate may help people avoid stereotyping consider...

In this paper, we propose a new and practical reliability-based hybrid automatic repeat request (RB-HARQ) scheme for irregular low-density parity-check (LDPC) codes. Irregular LDPC codes have an unequal error protection (UEP) property. Using property, find that the middle degree message nodes of are important HARQ systems. If pick out low reliable them retransmission, will reduce feedback. Moreover, system performance is as well original RB-HARQ scheme.

In this paper, a progressive hybrid automatic repeat request (HARQ) scheme on degree distribution for irregular low-density parity-check (LDPC) codes is proposed. scheme, lower nodes are retransmitted. During the process of choosing retransmission, not only but also unequal error protection (UEP) property and iterative decoding LDPC considered. Compared with initial Degree Distribution Based HARQ (DDB-HARQ), proposed has better performance.

Associating a life-threatening crisis with geographic locality can stigmatize people from that area. However, such strategy may reduce the public blame attributed to government because perceived foreign threat establishes scapegoat, which transfers blame. In context of COVID-19 pandemic, we investigated whether “Chinese Virus” label placed on has elicited opposition Chinese immigrants and reduced federal government. We used survey experiment during list measure threat. The descriptive...
