Presenting Objects for Random Allocation

SSRN Electronic Journal, 2022
AbstractFor random allocation, whether a desirable rule exists or not hinges on the domain of agents' preferences, whose formation is affected by how objects are presented. We hence propose a model studying how to present objects so that the induced preference domain allows for designing a good rule.

Random allocation II

BMJ, 2009
A randomised single blind controlled trial investigated whether pelvic floor muscle training during pregnancy prevented urinary incontinence during and after pregnancy. The trial recruited healthy nulliparous women when they attended their first routine ultrasound.

Randomized allocation processes

Random Structures & Algorithms, 2001
AbstractMany dynamic resource allocation and on‐line load balancing problems can be modeled by processes that sequentially allocate balls into bins. The balls arrive one by one and are to be placed into bins on‐line without using a centralized controller.

Random sampling versus random allocation

BMJ, 2011
Researchers investigated the effects of providing people with evidence based information about colorectal cancer and screening. A randomised controlled study design was used. The intervention was a brochure that included personalised risk of colorectal cancer, available screening options with possible benefits and harm, plus information on prevention ...

Stratified random allocation

BMJ, 2013
Researchers investigated the effects of manual lymph drainage on the development of lymphoedema related to breast cancer. A randomised single blinded controlled trial was performed. The intervention was a six months’ treatment programme consisting of guidelines about prevention of lymphoedema, exercise therapy, and manual lymph drainage.

Additive Decompositions, Random Allocations, and Threshold Phenomena

Combinatorics, Probability and Computing, 2004
An additive decomposition of a set $I$ of nonnegative integers is an expression of $I$ as the arithmetic sum of two other such sets. If the smaller of these has $p$ elements, we have a $p$-decomposition. If $I$ is obtained by randomly removing $n^{\alpha}$ integers from $\{0,\dots,n-1\}$, decomposability translates into a balls-and-urns problem, which ...

Controlled trials: allocation concealment, random allocation, and blinding

BMJ, 2015
The efficacy of nicotine patches in pregnant women who smoke was investigated using a randomised placebo controlled trial. The intervention was the administration of 16 hour nicotine patches until the time of delivery. Participants were 402 pregnant women older than 18 years who smoked at least five cigarettes a day and whose babies were between 12 and

Randomization. Part 3: Allocation concealment and randomization implementation

American Journal of Orthodontics and Dentofacial Orthopedics, 2012
Randomization consists of 3 steps: generation of the random allocation sequence, allocation concealment, and implementation of the random allocation sequence. In the previous 2 articles, we discussed the methods to generate the random allocation sequence (the Table summarizes these methods); in this final article on randomization, we will discuss ...

Adaptive allocation in randomized controlled trials

Controlled Clinical Trials, 1985
Adaptive allocation has been proposed as a procedure to reduce the risk of chance imbalance of important prognostic factors in randomized controlled trials when the number of prognostic factors is large. In this article, minimization, a type of adaptive allocation, is compared to simple randomization and stratified allocation in a series of Monte Carlo
