This is really the overarching question associated with model calibration: are the models good enough? But the question has to be asked in the framework of what the models will be asked to do, which is to evaluate remedial alternatives. (Problem identification is usually the first step in model evaluation; see, e.g., Ditmars et al., 1987.) The following sketch and discussion provide a framework...

Attachment theory is presented in this article as involving embodied relational processes within complex relational systems. Two narrative-like ‘events’ are re-presented to illustrate very young children playfully relating – connecting and communicating interand intrasubjectively. The ethnographic-inspired research methods included the researcher as a participant observer, an outsider, an other...

provided x is sufficiently large. An asymptotic formula of type (1) Df (x; q, a) = (1 +O((log x)))Df (x; q) , in which the error term is smaller than the main term by a suitable power of log x, is good enough for basic applications. More important than the size of the error term is the range where (1) holds uniformly with respect to the modulus q. In this paper we consider the problem for the d...

Methods that might work are not good enough; what is preserved today should be reliably useful whenever someone wants it. Here, “reliably” is intended to include “without error introduced after the data leaves the purported author’s control.” Prior proposals—called “transformative migration” and “preservation emulation”—fail because what they save is confounded with details about today’s inform...

(Non-)portability of Prolog programs is widely considered as an important factor in the lack of acceptance of the language. Since 1995, the core of the language is covered by the ISO standard 13211-1. Since 2007, YAP and SWI-Prolog have established a basic compatibility framework. This article describes and evaluates this framework. The aim of the framework is running the same code on both syst...

unproblematically, continuing on a trajectory set out in the 1880s, as if there were a giant conspiracy to chastise homosexuality through discussions of the homosexual body, then to more psychological markers, and finally back to the body in terms of the genetic arguments about homosexuality that are current today. I am not suggesting that homosexuality was not often spurned by scientists, but ...

There is overwhelming evidence suggesting that the real users of IR systems often prefer using extremely short queries (one or two individual words) but they try out several queries if needed. Such behavior is fundamentally different from the process modeled in the traditional test collection-based IR evaluation based on using more verbose queries and only one query per topic. In the present pa...

We show how one can use Hermite-Padé approximation and little q-Jacobi polynomials to construct rational approximants for ζq(2). These numbers are qanalogues of the well known ζ(2). Here q = 1 p , with p an integer greater than one. These approximants are good enough to show the irrationality of ζq(2) and they allow us to calculate an upper bound for its measure of irrationality: μ (ζq(2)) ≤ 10...

Introduction Many intergovernmental and governmental organizations produce their own interfaces for statistical data. With the exception of the Common Database which combines select data from many of the United Nations’ independent agencies, there is typically little cooperation for integrating data between agencies. Some universities have chosen to produce their own interface to merge data int...

This is a complement to the comparison theorem for improper integrals in the textbook. The vanilla version presented in the textbook is good enough to solve some very easy examples and it becomes exponentially gory with the complexity of the integral. Fortunately it is not hard to refine the statement in the book, and turn it into a powerful tool to estimate the convergence of arbitrarily compl...
