United we stand, divided we fall: a meta-analysis of experiments on clonal integration and its relationship to invasiveness

Fragmentation and vegetative regeneration from small fragments may contribute to population expansion, dispersal and establishment of new populations of introduced plants. However, no study has systematically tested whether a high capacity of vegetative regeneration is associated with a high degree of invasiveness. For small single-node fragments, the presence of internodes may increase regeneration capacity because internodes may store carbohydrates and proteins that can be used for regeneration. We conducted an experiment with 39 stoloniferous plant species to examine the regeneration capacity of small, single-node fragments with or without attached stolon internodes. We asked (1) whether the presence of stolon internodes increases regeneration from single-node fragments, (2) whether regeneration capacity differs between native and introduced species in China, and (3) whether regeneration capacity is positively associated with plant invasiveness at a regional scale (within China) and at a global scale. Most species could regenerate from single-node fragments, and the presence of internodes increased regeneration rate and subsequent growth and/or asexual reproduction. Regeneration capacity varied greatly among species, but showed no relationship to invasiveness, either in China or globally. High regeneration capacity from small fragments may contribute to performance of clonal plants in general, but it does not appear to explain differences in invasiveness among stoloniferous clonal species.

Productivity and Market Integration in American Communal Dairying, 1830-1875

In our late twentieth century experience, survival of an economy seems critically dependent on well established rights to private property and a return to labor that rewards greater effort. But that need not be so. History provides examples of micro-socialist economies that internally, at least, allow for little private property for participants and a constant return to labor that is independent of effort. Some such economies may even be termed 'successful,' if success is taken to mean survival over several generations. If these communities survived without conditions that are generally thought to be necessary for success, a question worth asking is how this occurred, for we can then shed some light on what really is necessary for economic survival. Addressing this issue emphasizes the critical role of time, for even if the microsocialist economies that we study here eventually became the merest shadow of their former selves, the fact that they did flourish for so long makes them a valuable counterexample, and hence, a phenomenon in need of explanation. We consider here the dairy industry of the Shakers, which was characterized by intensive efforts to increase productivity, in part through the use of market signals, but efforts that were also limited by the ideological goals of the community. The Shakers were (and are, but since it is the historical Shakers that concern this paper, the past tense will be used) a Christian communal group. Some of their distinctive beliefs included the existence of a male and female Godhead, from which followed sexual equality, and active communication between Believers (a Shaker term for members of the sect) and denizens of the spirit world. Practices of the Society (their official name is the United Society of Believers in Christ's Second Appearing, the second appearing being in the body of their foundress, an illiterate Englishwoman named Ann Lee) included pacifism, celibacy, confession of sins to elders, and joint or communal ownership of the Society's assets. Each Shaker received the same return for his or her labor: room, board, clothing, and the experience of divine proximity in a community of like minded Believers (Stein 1992).

Revisión de:Sport facing cultural diversity. Integration and intercultural dialogue in Europe: analysis and practical example, de Wiliam Gasparini y Aurélie Cometti

Con motivo de la celebracio?n en 2008 del An?o Europeo del Dia?logo Intercultural, el Con- sejo de Europa promovio? una serie de encuentros y foros de debate en torno al papel de Europa en la gestio?n de la inmigracio?n, desde sus mu?ltiples dimensiones. Entre ellas, se encuentra el a?mbito deportivo, por su papel socializador como elemento cultural de dia?logo e identidad, aun- que tambie?n como espacio de confrontacio?n y discriminacio?n, que concierne tanto a participantes como espectadores, desde una perspectiva global y local. Con el objetivo de contrastar experien- cias y reflexiones a este respecto, tuvo lugar la primera conferencia europea con el nombre ?De- porte y Diversidad?, celebrada en Estrasburgo y organizada por la Agencia para la Educacio?n a trave?s del Deporte, el Consejo de Europa - a trave?s del EPAS - y la Universidad de Estrasburgo.

European Integration and Europeanisation: Benefits and Disadvantages for Business. Bruges European Economic Policy (BEEP) Briefing 29/2013

European integration is a project of great economic importance for the 500 million consumers and 21 million companies in Europe. With the economic borders between Member States removed, Europeanisation becomes inevitable for companies. The paper proposes a framework to analyse the benefits and disadvantages for business that come with the process of European integration, structured according to the logic of the four fundamental freedoms of movement within the Internal Market (freedom of movement of goods, services, capital and people) complemented by the section on technology and innovation, and the general EU regulatory environment. Whereas the business decisions need to be taken on a case-by-case basis, taking into consideration firm’s own capabilities and resources as well as industry specificities, several recommendations for companies willing to Europeanise are made, based on an analysis of the regulatory macro-environment of the EU. Above all, any company willing to be successful in the EU has to become a learning organisation, responsive to the advancements of the macro-environment. The ability to anticipate the regulatory developments and to adjust one’s own business and corporate strategy accordingly is the key to achieving sustainable competitive advantage in the European Union.

“There’s No Place Like Home”: An Analysis of Rental Market Conditions and Coping Mechanisms in the Emerald City

This mixed-methods study analyzed quantitative and qualitative data on rental market conditions in the Seattle area, their effects on renters, and coping mechanisms used by renters. Data was collected from 111 individuals using an online survey and face-to-face interviews. While the focus of the study was on low-income renters and other marginalized populations, results show that a majority of renters surveyed are struggling to make ends meet, and that rental market conditions are impacting renters’ residential situations, as well as their life choices in other areas, such as education, their career, and decisions to have children. Future research should investigate these relationships further and in more detail, particularly for renters from marginalized populations, and investigate what types of solutions or improvements renters would like to see.

Equity market linkage and multinational trade accords: The case of NAFTA

This paper examines the impact of multinational trade accords on the degree of stock market linkage using NAFTA as a case study. Besides liberalizing trade among the U.S., Canada and Mexico, NAFTA has also sought to strengthen linkage among stock markets of these countries. If successful, this could lessen the appeal of asset diversification across the North American region and promote a higher degree of market efficiency. We assess the possible impact of NAFTA on market linkage using cross-correlations, multivariate price cointegrating systems, speed of convergence, and generalized variance decompositions of unexpected stock returns. The evidence proves robust and consistently indicates intensified equity market linkage since the NAFTA accord. The results also suggest that interdependent goods markets in the region are a primary reason behind the stronger equity market linkage observed in the post-NAFTA period. (c) 2005 Elsevier Ltd.

An automated failure mode and effect analysis based on high-level design specificication with behavior trees

Formal methods have significant benefits for developing safety critical systems, in that they allow for correctness proofs, model checking safety and liveness properties, deadlock checking, etc. However, formal methods do not scale very well and demand specialist skills, when developing real-world systems. For these reasons, development and analysis of large-scale safety critical systems will require effective integration of formal and informal methods. In this paper, we use such an integrative approach to automate Failure Modes and Effects Analysis (FMEA), a widely used system safety analysis technique, using a high-level graphical modelling notation (Behavior Trees) and model checking. We inject component failure modes into the Behavior Trees and translate the resulting Behavior Trees to SAL code. This enables us to model check if the system in the presence of these faults satisfies its safety properties, specified by temporal logic formulas. The benefit of this process is tool support that automates the tedious and error-prone aspects of FMEA.
