The participation of non-state actors in public decision-making and transdisciplinary research is increasingly regarded as
an effective means to cope with growing uncertainties and complexities in human–nature interactions. The management of natural
resources is expected to profit from a broader knowledge base and processes of social learning, thus allowing for potentially
more informed and creative decision-making. Communication is a key element of transmitting knowledge and fostering social
learning. This article introduces the special issue, which assembles contributions that discuss different methods, instruments,
tools, and models that have been developed in order to facilitate the transmission of information as well its selection and
aggregation. Each of the contributions is briefly reviewed. The approaches discussed here and in the individual papers aim
to foster learning in participatory processes. We argue that a key aspect is the degree to which methods are formalised. Formalisation
refers to the extent to which information is channelled in a certain way, leaving more or less scope for open communication.
Depending on the goals and context, more or less formalised methods can be employed. We conclude by highlighting the context-dependency
of participatory processes in natural resource management and indicate some directions for future research.

Because of inversion symmetry and particle exchange, all constituents of homonuclear diatomic molecules are in a quantum mechanically non-local coherent state; this includes the nuclei and deep-lying core electrons. Hence, the molecular photoemission can be regarded as a natural double-slit experiment: coherent electron emission originates from two identical sites, and should give rise to characteristic interference patterns. However, the quantum coherence is obscured if the two possible symmetry states of the electronic wavefunction ('gerade' and 'ungerade') are degenerate; the sum of the two exactly resembles the distinguishable, incoherent emission from two localized core sites. Here we observe the coherence of core electrons in N(2) through a direct measurement of the interference exhibited in their emission. We also explore the gradual transition to a symmetry-broken system of localized electrons by comparing different isotope-substituted species--a phenomenon analogous to the acquisition of partial 'which-way' information in macroscopic double-slit experiments. 相似文献

Cytotoxic T lymphocytes patrol our body in search for infected cells which they kill through the release of cytotoxic substances contained in cytotoxic granules. The fusion of cytotoxic granules occurs at a specially formed contact site, the immunological synapse, and is tightly controlled to ensure specificity. In this review, we discuss the contribution of two intracellular compartments, endosomes and cytotoxic granules, to the formation, function and disassembly of the immunological synapse. We highlight a recently proposed sequential process of fusion events at the IS upon target cell recognition. First, recycling endosomes fuse with the plasma membrane to deliver cargo required for the docking of cytotoxic granules. Second, cytotoxic granules arrive and fuse upon docking in a SNARE-dependent manner. Following fusion, membrane components of the cytotoxic granule are retrieved through endocytosis to ensure the fast, efficient serial killing of target cells that is characteristic of cytotoxic T lymphocytes. 相似文献

KLHL3 mutations cause familial hyperkalemic hypertension by impairing ion transport in the distal nephron 总被引:1,自引:0,他引:1

Familial hyperkalemic hypertension (FHHt) is a Mendelian form of arterial hypertension that is partially explained by mutations in WNK1 and WNK4 that lead to increased activity of the Na(+)-Cl(-) cotransporter (NCC) in the distal nephron. Using combined linkage analysis and whole-exome sequencing in two families, we identified KLHL3 as a third gene responsible for FHHt. Direct sequencing of 43 other affected individuals revealed 11 additional missense mutations that were associated with heterogeneous phenotypes and diverse modes of inheritance. Polymorphisms at KLHL3 were not associated with blood pressure. The KLHL3 protein belongs to the BTB-BACK-kelch family of actin-binding proteins that recruit substrates for Cullin3-based ubiquitin ligase complexes. KLHL3 is coexpressed with NCC and downregulates NCC expression at the cell surface. Our study establishes a role for KLHL3 as a new member of the complex signaling pathway regulating ion homeostasis in the distal nephron and indirectly blood pressure. 相似文献

Pre-existing neutralizing antibody provides the first line of defence against pathogens in general. For influenza virus, annual vaccinations are given to maintain protective levels of antibody against the currently circulating strains. Here we report that after booster vaccination there was a rapid and robust influenza-specific IgG+ antibody-secreting plasma cell (ASC) response that peaked at approximately day 7 and accounted for up to 6% of peripheral blood B cells. These ASCs could be distinguished from influenza-specific IgG+ memory B cells that peaked 14-21 days after vaccination and averaged 1% of all B cells. Importantly, as much as 80% of ASCs purified at the peak of the response were influenza specific. This ASC response was characterized by a highly restricted B-cell receptor (BCR) repertoire that in some donors was dominated by only a few B-cell clones. This pauci-clonal response, however, showed extensive intraclonal diversification from accumulated somatic mutations. We used the immunoglobulin variable regions isolated from sorted single ASCs to produce over 50 human monoclonal antibodies (mAbs) that bound to the three influenza vaccine strains with high affinity. This strategy demonstrates that we can generate multiple high-affinity mAbs from humans within a month after vaccination. The panel of influenza-virus-specific human mAbs allowed us to address the issue of original antigenic sin (OAS): the phenomenon where the induced antibody shows higher affinity to a previously encountered influenza virus strain compared with the virus strain present in the vaccine. However, we found that most of the influenza-virus-specific mAbs showed the highest affinity for the current vaccine strain. Thus, OAS does not seem to be a common occurrence in normal, healthy adults receiving influenza vaccination. 相似文献

The Role of Formalisation, Participation and Context in the Success of Public Involvement Mechanisms in Resource Management 总被引:1,自引:0,他引:1

In the face of complex and uncertain issues, one important goal of public participation in resource management and research is to foster communication and the inclusion of non-expert knowledge—thus the effective flow of information between project organisers and stakeholders. We compare different methods (instruments, tools) that were employed in the German–Austrian ‘PartizipA’ project to structure information flows in participatory processes. Depending on their goals and context, more or less ‘formalised’ and ‘participatory’ methods were applied, the most important being guided interviews, focus groups, agent-based modelling, nutrient modelling, cognitive mapping and group model building as well as the development of a common document. Two regional case studies, both concerned with European-induced institutional change, are portrayed in which the specific participatory methods were embedded. The Austrian case study involved the analysis and modelling of agricultural land use in the region of St. Pölten against the background of the reform of the Common Agricultural Policy, while the implementation of recent European water policy was the issue in the German agricultural region north of Osnabrück. Presenting both cases in their regional context, the applied methods are first described according to the logic of the entire respective process. Subsequently, the specific methods are systematically analysed and compared according to their objective, context and degrees of participation and formalisation. Finally, we evaluate all methods regarding their effectiveness in terms of goal attainment and their potential generalisation, seeking to respond to the question of when a particular method might best be used. 相似文献
