Adjustment Policies in Europe

This paper is focussed on a set of policies, some specifically agricultural, others taking the form of special provisions within, or exceptions to, economy wide measures that affect adjustment in the agricultural sector in a selection of European countries. The policies are those that affect entry to and exit from the sector and cover measures affecting both land and labour. These are predominantly taxation and social security measures (including specifically agricultural early retirement schemes), and the plethora of other laws and regulations that control land purchase, lease and conversion. The choice of countries has been determined mainly by the availability of information (France, Germany, Ireland, Norway), but those singled out for detailed treatment are generally those where there is significant intervention with a view to directing the movement of resources in and out of the sector. The paper will describe the measures and will attempt a qualitative assessment of their likely effects in a trade liberalisation or reform context. Before the country sections are embarked on, the paper describes some of the cultural, historical and structural features that are important to understanding the "adjustment" debate in Europe.Agricultural and Food Policy,

A Historical Perspective on Runtime Assertion Checking in Software Development

This report presents initial results in the area of software testing and analysis produced as part of the Software Engineering Impact Project. The report describes the historical development of runtime assertion checking, including a description of the origins of and significant features associated with assertion checking mechanisms, and initial findings about current industrial use. A future report will provide a more comprehensive assessment of development practice, for which we invite readers of this report to contribute information

Presume It Not: True Causes in the Search for the Basis of Heredity

Kyle Stanford has recently given substance to the problem of unconceived alternatives, which challenges the reliability of inference to the best explanation (IBE) in remote domains of nature. Conjoined with the view that IBE is the central inferential tool at our disposal in investigating these domains, the problem of unconceived alternatives leads to scientific anti-realism. We argue that, at least within the biological community, scientists are now and have long been aware of the dangers of IBE. We re-analyze the nineteenth-century study of inheritance and development (Stanford’s case study) and extend it into the twentieth century, focusing in particular on both classical Mendelian genetics and the studies by Avery et al. on the chemical nature of the hereditary substance. Our extended case studies show the preference of the biological community for a different methodological standard: the vera causa ideal, which requires that purported causes be shown on non-explanatory grounds to exist and be competent to produce their effects. On this basis, we defend a prospective realism about the biological sciences

The emerging structure of the Extended Evolutionary Synthesis: where does Evo-Devo fit in?

The Extended Evolutionary Synthesis (EES) debate is gaining ground in contemporary evolutionary biology. In parallel, a number of philosophical standpoints have emerged in an attempt to clarify what exactly is represented by the EES. For Massimo Pigliucci, we are in the wake of the newest instantiation of a persisting Kuhnian paradigm; in contrast, Telmo Pievani has contended that the transition to an EES could be best represented as a progressive reformation of a prior Lakatosian scientific research program, with the extension of its Neo-Darwinian core and the addition of a brand-new protective belt of assumptions and auxiliary hypotheses. Here, we argue that those philosophical vantage points are not the only ways to interpret what current proposals to ‘extend’ the Modern Synthesis-derived ‘standard evolutionary theory’ (SET) entail in terms of theoretical change in evolutionary biology. We specifically propose the image of the emergent EES as a vast network of models and interweaved representations that, instantiated in diverse practices, are connected and related in multiple ways. Under that assumption, the EES could be articulated around a paraconsistent network of evolutionary theories (including some elements of the SET), as well as models, practices and representation systems of contemporary evolutionary biology, with edges and nodes that change their position and centrality as a consequence of the co-construction and stabilization of facts and historical discussions revolving around the epistemic goals of this area of the life sciences. We then critically examine the purported structure of the EES—published by Laland and collaborators in 2015—in light of our own network-based proposal. Finally, we consider which epistemic units of Evo-Devo are present or still missing from the EES, in preparation for further analyses of the topic of explanatory integration in this conceptual framework

The reciprocal relationship between the state and union formation across Western Europe: policy dimensions and theoretical considerations

Although cohabitation and childbearing within cohabitation has increased dramatically in Europe over the past decades, the variation across Europe remains remarkable. Most studies on changing union formation have not explicitly addressed how state policies may be facilitating cohabitation or, alternatively, stalling the increase of cohabitation by privileging marriage. Indeed, the relationship between policies and union formation is complicated, as states may have passed legislation in response to increasing cohabitation. As a first step to understanding this reciprocal relationship, we provide here an overview of the policies that may impact union formation. Drawing on secondary sources and legal documents, we describe the policy dimensions that regulate the relationship between couples, and between couples and their children. We also discuss theoretical issues and explore examples from across Western Europe. As a whole, this overview raises questions about the changing “institution” of marriage, as well as the increasing “institutionalization” of cohabitation.Europe, cohabitation
