The Ultimate Culture Change Learning Session
Awareness of the importance of culture is growing at a fast rate but there is no consistent understanding about how to effectively evolve culture with a direct and sustainable impact on performance. This awareness-understanding gap helps to explain why most organizations report they don’t understand their culture and believe change is needed. Culture crises (Uber, etc.) gain widespread exposure and superficial tips and keys dominate the popular press. Leaders and change agents often feel lost in the wilderness as they try to piece together improvements that will impact culture. This will likely be the most performance-focused culture educational session you have experienced. The foundation is a series of insights about culture, climate and culture change from some of the top workplace culture pioneers in history. These insights are not widely understood and they are integrated in visual tools, flow charts, timelines and examples to accelerate learning regarding this important topic. You will learn a general framework for • Combining qualitative and quantitative methods to understand the current culture, climate and impact on outcomes • Engaging leadership and team members in improvement efforts • Techniques to sequence, prioritize, and phase improvement efforts to build momentum, deliver initial results, and sustain change efforts The session will also include a discussion about common obstacles and how to overcome them with a focus on shared learning as part of a phased improvement approach
Bürger(innen) auf Standortsuche: Erwartungen in Deutschland, Erfahrungen aus der Schweiz
Die zur Evaluierung des deutschen Standortauswahlgesetzes einberufene Kommission Lagerung hoch radioaktiver Abfallstoffe hat dem Gesetzgeber im Sommer 2016 ihren Abschlussbericht vorgelegt. Empfohlen wird ein umfangreiches Beteiligungssystem, das es der regionalen und überregionalen Öffentlichkeit ermöglichen soll, das Standortsuchverfahren kritisch und konstruktiv zu begleiten. Auf der regionalen Ebene sollen Regionalkonferenzen zum Einsatz kommen. Erfahrungen aus der Schweiz zeigen sowohl Chancen als auch Probleme
Global gradients in intraspecific variation in vegetative and floral traits are partially associated with climate and species richness
The study would not have been possible without the work of the
TRY initiative on plant traits (http://www.try-db.org) and the BIEN
database (http://bien.nceas.ucsb.edu/bien/). We thank all the BIEN
and TRY contributors. Furthermore, we thank Benjamin Blonder,
Melanie Harze, Ruben Milla, Clara Pladevall, Quentin Read, Marko
Spasojevic, Alexia Totte, Evan R. Weiher, Ian Wright and Gerhard
W. Zotz for providing additional information for their datasets.
Additionally, we thank Franziska Schrodt and anonymous reviewers for constructive and thoughtful suggestions on earlier versions
of this paper. Open Access funding was provided by Ulm University
under the DEAL-agreement.Aim: Intraspecific trait variation (ITV) within natural plant communities can be large,
influencing local ecological processes and dynamics. Here, we shed light on how ITV
in vegetative and floral traits responds to large-scale abiotic and biotic gradients (i.e.,
climate and species richness). Specifically, we tested whether associations of ITV with
temperature, precipitation and species richness were consistent with any of four hypotheses relating to stress tolerance and competition. Furthermore, we estimated the
degree of correlation between ITV in vegetative and floral traits and how they vary
along the gradients.
Location: Global.
Time period: 1975–2016.
Major taxa studied: Herbaceous and woody plants.
Methods: We compiled a dataset of 18,401 measurements of the absolute extent of
ITV (measured as the coefficient of variation) in nine vegetative and seven floral traits
from 2,822 herbaceous and woody species at 2,372 locations.
Results: Large-scale associations between ITV and climate were trait specific and
more prominent for vegetative traits, especially leaf morphology, than for floral
traits. The ITV showed pronounced associations with climate, with lower ITV values
in colder areas and higher values in drier areas. The associations of ITV with species
richness were inconsistent across traits. Species-specific associations across gradients were often idiosyncratic, and covariation in ITV was weaker between vegetative
and floral traits than within the two trait groups.
Main conclusions: Our results show that, depending on the traits considered, ITV either increased or decreased with climate stress and species richness, suggesting that
both factors can constrain or enhance ITV, which might foster plant-population persistence in stressful conditions. Given the species-specific responses and covariation
in ITV, associations can be hard to predict for traits and species not yet studied. We
conclude that consideration of ITV can improve our understanding of how plants cope
with stressful conditions and environmental change across spatial and biological scales
Guaranteeing Transparency in Nuclear Waste Management: Monitoring as Social Innovation: Introduction to the Thematic Focus
Guaranteeing Transparency in Nuclear Waste Management: Monitoring as Social Innovation. Introduction to the Thematic Focus
Toward a repository for high-level radioactive waste: perspectives and approaches
The future is unpredictable. Under these circumstances, how can we plan and construct a nuclear waste repository that is supposed to safely store the waste for up to a million years - an endeavor that may in itself take more than a hundred years? In this introduction to the special topic on the future of nuclear waste disposal, we take a first look at this question by searching the literature for answers and by giving a short overview of the current status of site selection in different countries, including possible challenges.Die Zukunft ist unvorhersehbar. Wie können wir unter diesen Umständen ein Endlager für nukleare Abfälle planen und errichten, das die Abfälle für bis zu eine Million Jahre sicher aufbewahren soll - ein Unterfangen, das an sich schon mehr als hundert Jahre dauern kann? In dieser Einleitung zum Schwerpunktheft über die Zukunft der Atommüllentsorgung werfen wir einen ersten Blick auf diese Frage, indem wir in der Literatur nach Antworten suchen und einen kurzen Überblick über den aktuellen Stand der Standortwahl in verschiedenen Ländern geben, einschließlich möglicher Herausforderungen
Phylogenetics, flow-cytometry and pollen storage in <em>Erica</em> L. (Ericaceae) : Implications for plant breeding and interspecific crosses
With over 840 species Erica L. is one of the largest genera of the Ericaceae, comprising woody perennial plants that occur from Scandinavia to South Africa. According to previous studies, the northern species, present in Europe and the Mediterranean, form a paraphyletic, basal clade, and the southern species, present in South Africa, form a robust monophyletic group. In this work a molecular phylogenetic analysis from European and from Central and South African Erica species was performed using the chloroplast regions: trnL-trnL-trnF and 5´trnK-matK, as well as the nuclear DNA marker ITS, in order i) to state the monophyly of the northern and southern species, ii) to determine the phylogenetic relationships between the species and contrasting them with previous systematic research studies and iii) to compare the results provided from nuclear data and explore possible evolutionary patterns. All species were monophyletic except for the widely spread E. arborea, and E. manipuliflora. The paraphyly of the northern species was also confirmed, but three taxa from Central East Africa were polyphyletic, suggesting different episodes of colonization of this area. The inheritance path of chloroplast markers and the mitochondria region cox3 from the analysis of a controlled hybrid and its parents was tested. The maternal inheritance of organelles is described for the first time in Erica, enabling the hypothesis that incongruences between chloroplast and ITS marker trees may be the result of a reticulate evolution within the genus. An approximation of nuclear DNA amount by the quantification of the relative genome amount via flow cytometry with DAPI was assayed for selected samples, all revealing to have a similar genome size, with the exception of E. bauera that seemed to present a higher ploidy level. The vitality test of pollen grains after storage from two Erica species was carried out using a FDA solution and applying UV-light fluorescence microscopy techniques with a positive yield of up to two living cells within the pollen tetrad after finalizing the storage period
