Restrukturierungsprozesse einer Stadt-Umland Ökonomie : Veränderung der Wirtschaftsstruktur im Agglomerationsraum Basel
No full textGlobalization trends lead to economic processes of
restructuring in the City of Basle and its surrounding
area. Characteristics of this development are: loss of Jobs, increasing unemployment, sectoral restructuring and flexible forms of production and employment.Tendencies towards a spatial concentration or deconcentration of certain economic branches that can be observed on a global scale, can only be found to a smaller degree in the economic
region of Basle. Distinctive regional features and Basle's position in the national city-system modify this development.The restructuring processes have different effects on the city and the suburban zone. Within the surrounding areas there is no homogenous development. Therefore, it is necessary to maximize the existing opportunities and to implement equalizing mechanisms that secure the competitiveness of the region as a whole

A linear dominance hierarchy among clones in chimeras of the social amoeba Dictyostelium discoideum
No full textAmoebae from different clones of Dictyostelium discoideum aggregate into a common slug, which migrates towards light for dispersal, then forms a fruiting body consisting of a somatic, dead stalk, holding up a head of living spores. Contributions of two clones in a chimera to spore and stalk are often unequal, with one clone taking advantage of the other's stalk contribution. To determine whether there was a hierarchy of exploitation among clones, we competed all possible pairs among seven clones and measured their relative representation in the prespore and prestalk stages and in the final spore stage. We found a clear linear hierarchy at the final spore stage, but not at earlier stages. These results suggest that there is either a single principal mechanism or additive effects for differential contribution to the spore, and that it involves more than spore/stalk competition
THE SPARTAN SCHOOL OF INSTITUTIONAL ECONOMICS AT MICHIGAN STATE UNIVERSITY
No full textHeterodox scholarship at Michigan State University (MSU) was influenced by the institutional economics of John R. Commons at Wisconsin. But it was far from monolithic and had many other sources and originality of its own. A case can be made that the center of institutional economics moved across Lake Michigan from Madison to East Lansing and blossomed in the second half of the 20th century with such Wisconsin Ph.D's as Raleigh Barlowe, Warren Samuels, Allan Schmid, Harry Trebing, and others. Equally important in making MSU a center of institutional economics were scholars from other institutional backgrounds such as Paul Strassmann, economic development; Robert Solo, science and technology; James Shaffer, agricultural marketing and consumer behavior; Nicholas Mercuro, law and economics; and others.Institutional and Behavioral Economics,
Co-occurrence in nature of different clones of the social amoeba, Dictyostelium discoideum
No full textThe social amoeba, Dictyostelium discoideum, produces a multicellular fruiting body and has become a model system for cell-cell interactions such as signalling, adhesion and development. However, unlike most multicellular organisms, it forms by aggregation of cells and, in the laboratory, forms genetic chimeras where there may be competition among clones. Here we show that chimera formation is also likely in nature, because different clones commonly co-occur on a very small scale. This suggests that D. discoideum will likely have evolved strategies for competing in chimeras, and that the function of some developmental genes will be competitive. Natural chimerism also makes D. discoideum a good model organism for the investigation of issues relating to coexistence and conflict between cells
Researcher Centric Methodology (RCM) for Indigenomics
No full textThis project was presented as part of the Indigenomics NOW conference in 2024 with the Global Centre of Indigenomics.
In a world increasingly engaged with the concept of reconciliation, policymakers must navigate the unique needs of vulnerable communities, many of which face prohibitive barriers to have a seat at the table.
In this talk Strassmann introduces this as a basic human capital coordination problem leading to systematic unintended consequences and proposes a solution: Researcher-Centric Methodology (RCM), a revolutionary approach to methodology that puts the the researcher’s own insights and lived experiences as tools for analyzing complex social issues to the test. RCM encourages researchers to incorporate perspectives often systematically excluded from the field, bridging gaps in representation to create more inclusive, impactful policies
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The costs and benefits of being a chimera
No full textMost multicellular organisms are uniclonal. This is hypothesized to be because uniclonal organisms function better than chimeras (non-clonal organisms), owing to reduced levels of internal genetic conflict. We tested this idea using the social amoeba or slime mold Dictyostelium discoideum. When starving, the normally solitary amoebae aggregate to form a differentiated multicellular slug that migrates towards light and forms a fruiting body, facilitating the dispersal of spores. We added 107 amoebae to Petri plates containing 1, 2, 5 or 10 clones mixed together. We found an intrinsic cost to chimerism: chimeric slugs moved significantly less far than uniclonal slugs of the same size. However, in nature, joining with other clones to form a chimera should increase slug size, and larger slugs travel further. We incorporated this size effect into a second experiment by giving chimeras more cells than single clones (single clones had 106 cells, two-clone chimeras had 2 x 106 cells and so on). The uniclonal treatments then simulated a clone in a mixture that refuses to form chimeras. In this experiment, chimeras moved significantly further than the uniclonal slugs, in spite of the intrinsic cost. Thus, chimerism is costly, which may be why it evolves so seldom, but in D. discoideum the benefits of large size appear to compensate
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
