Feedback is central to the development of effective learning, yet is comparatively underresearched. This article seeks to examine the notion of written feedback on assignments and argue that this feedback process is more complex than is sometimes acknowledged. The author illustrates the problematic nature of assignment feedback by drawing on a large-scale questionnaire survey conducted across e...

A variety of proposals for preferred methodological approaches has been advanced in the recent artificial intelligence (AI) literature Rather than advocating a particular approach, this article attempts to explain the apparent confusion of efforts in the field in terms of differences among underlying methodological perspectives held by practicing researchers The article presents a review of suc...

Horizontal mechanisms are structural overlays (such as roles and groups) and non-structural devices (such as physical co-location) that are designed to facilitate cross-unit collaboration. The objective of this study is to increase our cumulative knowledge about what top-down mechanisms are being used to promote the coordination of IS activities across corporate/division boundaries. Proposition...

We initiate the study of extractability obfuscation (a.k.a. differing-inputs obfuscation), a notion first suggested by Barak et al. (JACM 2012): An extractability obfuscator eO for a class of algorithmsM guarantees that if an efficient attacker A can distinguish between obfuscations eO(M1), eO(M2) of two algorithms M1,M2 ∈M, then A can efficiently recover (given M1 and M2) an input on which M1 ...

The observation that concepts from quantum information has generated many alternative indicators of quantum phase transitions hints that quantum phase transitions possess operational significance with respect to the processing of quantum information. Yet, studies on whether such transitions lead to quantum phases that differ in their capacity to process information remain limited. Here we show ...

This study investigated the role probabilistic and deductive relations play in the reasoning process. It was predicted that when taking an analytic stance to a problem, it would take longer to evaluate inferences when asked how probable it is that the conclusion is true, than when asked whether the conclusion follows or not from the premises. Contrary to this prediction, people responded faster...

The choice of a dialysis treatment depends on many factors, both medical and non-medical. A full and rational treatment requires easy access to a transplantation programme and to all dialysis modalities, extracorporeal or peritoneal. Presently, haemodialysis (HD) is used almost exclusively for in-centre or limited care treatment, peritoneal dialysis (PD) being preferred for home treatment. On H...

OBJECTIVES Sustainability is a highly desired outcome of health promotion programs, yet it often eludes program planners looking to achieve it. This study aimed to uncover how the goal of program sustainability was interpreted by key stakeholders from three fall prevention program demonstration sites. METHOD Collected as part of a larger study on program sustainability that made use of a mult...
