Evaluation of Interprofessional Practice Education for Master of Social Work Students [PDF]

open access: yes, 2022
As interprofessional education (IPE) continues to grow as part of social work programs, it is important to evaluate how best to engage students in understanding this material and explore possible barriers.

Difficulty Scaling in Proof of Work for Decentralized Problem Solving

open access: yesLedger, 2020
We propose DIPS (Difficulty-based Incentives for Problem Solving), a simple modification of the Bitcoin proof-of-work algorithm that rewards blockchain miners for solving optimization problems of scientific interest.

Bitcoin: a new proof-of-work system with reduced variance

open access: yesFinancial Innovation, 2023
Since its inception, bitcoin has used the popular consensus protocol proof-of-work (PoW). PoW has a well-known flaw: it distributes all rewards to a single miner (or pool) who inserts a new block.

The Future of Social Work Education: A Guide to Developing, Implementing, and Assessing e-Simulations

open access: yes, 2022
Advances in technology, an increase in non-traditional students, a new generation of e-learners, the COVID-19 pandemic’s impact on education and practice, and the emergence of greater practitioner and client adoption of telebehavioral health present ...

How to Prove Work: With Time or Memory

open access: yesIEEE Access, 2022
Proposed by Dwork and Naor (Crypto’ 92) as an anti-spam technique, proof-of-work is attracting more attention with the boom of cryptocurrencies. A proof-of-work scheme involves two types of participants, $\textit {i.e.}$ , provers and verifiers ...

A Novel and Robust Hybrid Blockchain and Steganography Scheme

open access: yesApplied Sciences, 2021
Data security and data hiding have been studied throughout history. Studies show that steganography and encryption methods are used together to hide data and avoid detection.

Non-interactive Proofs of Proof-of-Work

open access: yes, 2020
Decentralized consensus protocols based on proof-of-work (PoW) mining require nodes to download data linear in the size of the blockchain even if they make use of Simplified Payment Verification (SPV). In this work, we put forth a new formalization of proof-of-work verification by introducing a primitive called Non-Interactive Proofs of Proof-of-Work ...

Pebbling and Proofs of Work [PDF]

open access: yes, 2005
We investigate methods for providing easy-to-check proofs of computational effort. Originally intended for discouraging spam, the concept has wide applicability as a method for controlling denial of service attacks. Dwork, Goldberg, and Naor proposed a specific memory-bound function for this purpose and proved an asymptotically tight amortized lower ...

Some remarks on proof-theoretic semantics [PDF]

open access: yes, 2015
This is a tripartite work. The first part is a brief discussion of what it is to be a logical constant, rejecting a view that allows a particular self-referential “constant” • to be such a thing in favour of a view that leads to strong normalisation ...
