Probiotics: Finding the Right Regulatory Balance
Some products marketed as drugs should be excused from Phase I trials, but safety and efficacy claims for dietary supplements should be more tightly regulated
Understanding disease control: influence of epidemiological and economic factors
We present a local spread model of disease transmission on a regular network
and compare different control options ranging from treating the whole
population to local control in a well-defined neighborhood of an infectious
individual. Comparison is based on a total cost of epidemic, including cost of
palliative treatment of ill individuals and preventive cost aimed at
vaccination or culling of susceptible individuals. Disease is characterized by
pre- symptomatic phase which makes detection and control difficult. Three
general strategies emerge, global preventive treatment, local treatment within
a neighborhood of certain size and only palliative treatment with no
prevention. The choice between the strategies depends on relative costs of
palliative and preventive treatment. The details of the local strategy and in
particular the size of the optimal treatment neighborhood weakly depends on
disease infectivity but strongly depends on other epidemiological factors. The
required extend of prevention is proportional to the size of the infection
neighborhood, but this relationship depends on time till detection and time
till treatment in a non-nonlinear (power) law. In addition, we show that the
optimal size of control neighborhood is highly sensitive to the relative cost,
particularly for inefficient detection and control application. These results
have important consequences for design of prevention strategies aiming at
emerging diseases for which parameters are not known in advance
Primordialists and Constructionists: a typology of theories of religion
This article adopts categories from nationalism theory to classify theories of religion. Primordialist explanations are grounded in evolutionary psychology and emphasize the innate human demand for religion. Primordialists predict that religion does not decline in the modern era but will endure in perpetuity. Constructionist theories argue that religious demand is a human construct. Modernity initially energizes religion, but subsequently undermines it. Unpacking these ideal types is necessary in order to describe actual theorists of religion. Three distinctions within primordialism and constructionism are relevant. Namely those distinguishing: a) materialist from symbolist forms of constructionism; b) theories of origins from those pertaining to the reproduction of religion; and c) within reproduction, between theories of religious persistence and secularization. This typology helps to make sense of theories of religion by classifying them on the basis of their causal mechanisms, chronology and effects. In so doing, it opens up new sightlines for theory and research
The deindustrialisation/tertiarisation hypothesis reconsidered: a subsystem application to the OECD7
The diffusion of outsourcing, both national and international, and
vertical FDIs among manufacturing firms, along with the higher integra-
tion of business services in manufacturing, has recently led to question
the empirical evidence supporting the Deindustrialisation/Tertiarisation
(DT) hypothesis. Rather than a \real" phenomenon, it has been argued,
DT would be an \apparent" one, mainly due to the reorganization of
production across national and sectoral boundaries.
The empirical studies that have dealt with the topic so far have
not been able to effectively rule out such possibility, because of two
main limitations: the sectoral level of the analysis and/or the national
focus. In order to overcome them, the paper carries out an appreciative
investigation of the actual extent of the DT occurred in the OECD
area over the '80s and the '90s by moving from a sector to a subsystem
perspective, thus retaining both direct and indirect relations, and by
referring to a \pseudo-World" of 7 OECD countries, thus taking into
account the \global" dimension of the phenomenon.
The results strongly support the DT hypothesis: although the weight
of business sector services in the manufacturing subsystem increased,
acting as a counterbalancing tendency to the manufacturing decline,
subsystem shares significantly decreased, thus confirming DT as a more
fundamental trend of modern economies
Democracy in trade unions, democracy through trade unions?
Since the Webbs published Industrial Democracy at the end of the nineteenth century, the principle that workers have a legitimate voice in decision-making in the world of work – in some versions through trade unions, in others at least formally through separate representative structures – has become widely accepted in most west European countries. There is now a vast literature on the strengths and weaknesses of such mechanisms, and we review briefly some of the key interpretations of the rise (and fall) of policies and structures for workplace and board-level representation. We also discuss the mainly failed attempts to establish broader processes of economic democracy, which the eclipse of nationally specific mechanisms of class compromise makes again a salient demand. Economic globalization also highlights the need for transnational mechanisms to achieve worker voice (or more radically, control) in the dynamics of capital-labour relations. We therefore examine the role of trade unions in coordinating pressure for a countervailing force at European and global levels, and in the construction of (emergent?) supranational industrial relations. However, many would argue that unions cannot win legitimacy as democratizing force unless manifestly democratic internally. We therefore revisit debates on and dilemmas of democracy within trade unions, and examine recent initiatives to enhance democratization
Long-run convergence in a neo-Kaleckian open-economy model with autonomous export growth
The crisis sensitivity of European countries and regions: stylized facts and spatial heterogeneity
We investigate the impact of the recent global recession on European countries and regions. We first identify the heterogeneous impact of the global recession on individual European countries and regions. We then discuss three classes of explanations for spatial heterogeneity in the severity of the crisis: (i) the extent to which countries are integrated in the global economy via financial and trade linkages, (ii) differences in the institutional framework of countries and (iii) differences in their sectoral composition. We show that especially variation in the sectoral composition contributes to the variation in the effects of the current crisis, both at the country level and at the detailed regional level across Europe. © The Author 2011.

Kaldor-Verdoorn's Law and Increasing Returns to Scale: A Comparison Across Developed Countries
The objective of this study is to investigate the validity of the Kaldor-Verdoorn's Law in explaining the long run determinants of the labor productivity growth for the manufacturing sector of some developed economies (Western European Countries, Australia, Canada, Japan and United States). We consider the period 1973-2006 using data provided by the European Commission - Economics and Financial Affairs. Our findings suggest that the law is valid for the manufacturing as countries show increasing returns to scale. Capital growth and labor cost growth do not appear important in explaining productivity growth. The estimated Verdoorn coefficients are found to be substantially stable throughout the period
