In the 1990s, while there was a large decline in property-related crime along the U.S.Mexico border, violent crime rates began to converge to the national average. At the same time, legal and illegal immigration from Mexico surged and border enforcement rose to unprecedented levels. In this paper, we investigate the relationship between border county crime rates, immigration and enforcement sin...

Sorensen (1985) has argued that ‘vague’ is itself a vague predicate; it is just as sorites-prone as its positive instances. This result has been exploited by Hyde (1994) in an ingenious attempt to establish that vague predicates must necessarily suffer from higher-order vagueness. More precisely, Hyde has argued that the vagueness of ‘vague’ ensures that the “paradigmatic conception”, according...

Dear Editor: We read with great interest the article by Namratha and Shetty entitled “A Technique to Evaluate Custom Tray Border Extensions Before Peripheral Molding.” Articles related to evaluation of denture border extensions are numerous, but there is marked paucity of literature regarding evaluation of border extensions of custom trays before border molding. The authors have introduced a co...

Engel & Rogers (1996) find that crossing the US–Canada border can considerably raise relative price volatility and that exchange rate fluctuations explain about one-third of the volatility increase. Using a decomposition method, this study re-evaluates the border effect. It is shown that cross-country heterogeneity in price volatility can induce a bias in measuring the border effect unless prop...

The paper analyses cross-border co-operation with regard to its degree of formalization. Herewith, the focus is not on single cross-border organizations, but on the encompassing governance systems in the respective regions. That means that the specific combination of differently organized cross-border arrangements is analyzed. Cross-border governance systems are facing multiple governance chall...

Border regions are likely to play a critical role within the spatial dynamics initiated by the enlargement of the EU. This paper deals with the effects of integration on labour markets in border regions. Within the framework of different theoretical approaches, the effects of integration on labour markets in border regions are analysed. Furthermore, we investigate empirically the degree of labo...

The composition of chlorophyll-precursor pigments, particularly the contents of monovinyl (MV) and divinyl (DV) protochlorophyllides (Pchlides), in etiolated tissues of higher plants were determined by polyethylene-column HPLC (Y. Shioi, S. I. Beale [1987] Anal Biochem 162: 493-499), which enables the complete separation of these pigments. DV-Pchlide was ubiquitous in etiolated tissue of higher...

Brief Overview The socio-political history of what is now the Mexico-U.S. border region is marked by conquest and divorce, a literal splitting of a once continuous land and related people; separate since 1848, but also increasingly integrated since the initiation of the North American Free Trade Agreement (NAFTA) in 1994. As “distant neighbors,” Mexico and the United States share much—economica...

The Hippo pathway is a key signaling cascade in controlling organ size. The core components of this pathway are two kinases, Hippo (Hpo) and Warts (Wts), and a transcriptional coactivator, Yorkie (Yki). Yes-associated protein (YAP, a Yki homolog in mammals) promotes epithelial-mesenchymal transition and cell migration in vitro. Here, we use border cells in the Drosophila ovary as a model to stu...

T-region transfer from wild-type Agrobacterium strains is thought to be an orientated process, starting at the right border repeat and terminating at the left border repeat of the T-region. Here we demonstrate that a right border repeat in the inverted orientation relative to the onc-genes can also mediate transfer of the T-region to the plant cell, although with lower efficiency as a border re...
