Geographical scale and the role of firm migration in spatial economic dynamics

Spatial economic change can be decomposed in it's demographic constituents firm formation, closure, relocation and growth. This paper focusses on the role of relocation in the balancing equation of spatial economic dynamics: Total Change(zone i) = New firms(i)-Closures(i)+ Growth(i)-Decline(i)+ Inmoves(i)-Outmoves(i). Whereas the other components are scale invariant (i.e. a firm birth is a birth whether measured at the local or the regional level) for firm relocation the geographical scale is very important. The larger the size of the region, the smaller the number of border crossing relocations. The question about the role of firm migration in regional economic change can therefore only be answered taking into account the geographical scale. In this paper we will answer this question for various geographical scales. The data that we use are from the longitudinal business register of the province of Gelderland, in the east of the Netherlands, covering the period 1988-2002.

A model of internal firm relocation in the Netherlands

This paper presents a model of internal relocation of firms in the Netherlands. Firm relocation is driven both by firm internal factors, such as growth, age, and type of activity, as well as external factors, relating to the business cycle, the geographical environment, the composition of the labour force, and the composition of the firm popuation, as well as linkages with other firms. Using a unique longitudinal database of firms in the Province of Gelderland in the Netherlands, we specify and estimate two related models of firm relocation. The decomposition of the migration process in two subprocesses is consitent with the theory of a two stage decision process, whereby in th first stage the firm decides to move, and in the second step it chooses an alternative destination. Different factors are important in both stages of the process.

In search of a modelling strategy for projecting internal migration in European countries - Demographic versus economic-geographical approaches

Internal migration is the most volatile and difficult to predict component of regional demographic change. A pure demographic approach using age and sex-specific parameters of migration intensities cannot fully capture the migration trends over time. One of the approaches that can be used for a better description of past trends and forecasting of future trends is to use additional non-demographic information such as regional economic indicators. In this paper we compare the predictive performance of pure demographic and extended economic-geographical models using data of four European countries at the so-called NUTS 2 level. The models are nested within a GLM specification%2C that allows both demographic and extended models to be written as specific cases of loglinear models. Therefore model fit and performance can be compared directly.

Further steps of hepatic stimulatory substance purification

The hepatic stimulatory substance (HSS) extracted from weanling rat livers was purified 381,000-fold using chromatographic techniques including nondissociating polyacrylamide gel electrophoresis (nondenaturing PAGE). The activity of this highly purified HSS, named Acr-F4, was assessed in two in vivo models. In 40% hepatectomized rats, it produced a fivefold increase in the proliferative rate normally seen following this partial hepatectomy. In Eck fistula dogs, the level of base increase in hepatocyte renewal was amplified threefold by an infusion of Acr-F4 (50 ng/kg/day). Acr-F4 had no influence on the regenerative response of the kidney following a unilateral nephrectomy or of the bowel following a 40% resection of the small bowel. On the basis of these findings, it can be concluded that HSS (Acr-F4) has a high biological activity and is organ specific. © 1991 Plenum Publishing Corporation

Etiese Besluitneming Volgens 1 Johannes

How to come to ethical decisions is an important question, both for individuals and religious institutions. In this article the way is discussed in which the author(s) of the Letters of John (especially 1 John) encourages the recipients of the Letters to come to the correct ethical decisions. He links all such decisions to the tradition they share, which corresponds to the truth they also share. The Spirit will lead and teach them accordingly.Article in Afrikaan

Historians and miracles: The principle of analogy and antecedent probability reconsidered

Most Biblical scholars and historians hold that the investigation of a miracle report lies outside of the rights of historians acting within their professional capacity. In this article, I challenge this assertion and argue to the contrary: Historians are within their professional rights to investigate miracle claims and to adjudicate on the historicity of the events. I present a positive case for the historian’s right to adjudicate on miracle claims and address two major objections to this conclusion:the principle of analogy and antecedent probability. At times I use the resurrection of Jesus as an example. This is the first of two articles. In the second, I will address three additional common objections: the theological objection, the lack of consensus and miracle claims in multiple religions
