There are some tools that help system administrators administer machines and networks using graphical user interface and Web interface. This paper presents a Web-based system that automates some processes to connect machines to a network, create accounts, mount remote home directories, set mailing lists, and so on by cooperating with multiple servers, and describes its implementation. By introd...

False claims are a key feature of confabulation, delusion, and anosognosia. In this paper we consider the role of motivational factors in such claims. We review motivational accounts of each symptom and consider the evidence adduced in support of these accounts. In our view the evidence is strongly suggestive of a role for motivational factors in each domain. Before concluding, we widen the foc...

Latin America led the world in introducing individual retirement accounts intended to complement or replace defined benefit state-sponsored, pay-as-you-go systems. After Chile implemented the first system in 1981, a number of other Latin American countries incorporated privately managed individual accounts as part of their retirement income systems beginning in the 1990s. This article examines ...

Although HSAs were legislated through a federal initiative, the availability of qualifying high-deductible health coverage depends partly on states. As the primary regulators of health insurance, states can choose whether to allow insurance companies to sell high-deductible policies. This issue brief covers the key issues that state officials need to know about HSAs—including what they are, how...

Detecting and suspending fake accounts (Sybils) in online social networking (OSN) services protects both OSN operators and OSN users from illegal exploitation. Existing social-graph-based defense schemes effectively bound the accepted Sybils to the total number of social connections between Sybils and non-Sybil users. However, Sybils may still evade the defenses by soliciting many social connec...

This paper deals with the question: what are the key requirements for a physical system to perform digital computation? Oftentimes, cognitive scientists are quick to employ the notion of computation simpliciter when asserting basically that cognitive activities are computational. They employ this notion as if there is a consensus on just what it takes for a physical system to compute. Some cogn...

Faces are an important and unique class of visual stimuli, and have been of interest to neuroscientists for many years. Faces are known to elicit certain characteristic behavioral markers, collectively labeled "holistic processing", while non-face objects are not processed holistically. However, little is known about the underlying neural mechanisms. The main aim of this computational simulatio...

Some assertions are epistemically defective. True story: Shortly after moving to South Bend, Malou mentioned that she was surprised to see so many gulls around town. I thought for a moment, then replied: “You know, those birds fly all the way over here from Lake Michigan.” Unfortunately, knowledgeable Mark overheard my assertion, and promptly said: “You don’t know what you’re talking about. Our...

Economists have traditionally eschewed direct measures of well-being on methodological grounds: the private nature of experience and the discomfort of making interpersonal comparisons. Instead, income is often used as a proxy for opportunities and well-being. If people are not fully rational, however, their choices will not necessarily maximize their experienced utility, and increasing their op...
