Given that the core issues of attention research have been recognized for millenia, we do not know as much about attention as we should. I argue that the reasons for this failure are (1) we create spurious dichotomies, (2) we reify attention, treating it as a cause, when it is an effect, and (3) we equate a collection of facts with a theory. In order to correct these errors, we need a new techn...

Is the Introspection Thesis true? It certainly isn’t obvious. Introspection is the faculty by which each of us has access to his or her own mental states. Even if we were to suppose that mental states are identical to brain states, it doesn’t follow immediately from this supposition that we can introspect our mental states as brain states. This point is analogous to the following. It doesn’t fo...

conomists love to say that there is no such thing as a free lunch. But the Chilean government agency responsible for school grants, Junta Nacional de Auxilio Escolar y Becas (JUNAEB), is an exception to the rule. During the school year, JUNAEB provides breakfast and lunch for 2 million children in primary and secondary public schools. In a developing country where about 14 percent of children u...

We propose a new negation rule for logic programming which derives existentially closed negative literals, and we de ne a version of completion for which this rule is sound and complete. The rule is called \Negation As Instantiation" (NAI). According to it, a negated atom succeeds whenever all the branches of the SLD-tree for the atom either fail or instantiate the atom. The set of the atoms wh...

conclusions independent variables such as sex, age, hdl-c, sys-bp, bmi, smoking, cholesterol and hs-crp were considered as influencing variables, and education, marital status, disease history, height, waist circumference, diastolic blood pressure and low density lipoprotein were removed from the models. background cardiovascular disease is considered as one of the most common diseases, causing...

A sound and complete semantics is given for sequential, depth-rst logic programming with a version of negation as failure. The semantics is logical in the sense that it is built up only from valuation functions (multi-valued logic interpretations in the style of Fitting and Kunen) and logically-motivated equivalence relations between formulas. The notion of predicate folding and unfolding with ...

introduction: of the factors leading to false negative results in mammography is breast tissue density, and by increasing the density of breast tissue in mammography, the mammography sensitivity decreases. on the other hand, increasing the breast tissue density leads to increased risk of breast cancer. various factors such as inheritance, genetics, hormonal and reproductive factors, and nutriti...

background: beside various factors for producing diabetes, it seems that chronic hepatitis c, hiv/hcv co-infection, and anti-retroviral treatment especially including protease inhibitors may predispose to diabetes. this study conducted to determine prevalence of diabetes in hiv and hcv patients. methods: the registries of 150 hcv patients, 50 hiv patients and 90 hiv/hcv co-infected patients in ...
