T1 - Sociocultural valuation of ecosystem services for operational ecosystem management: mapping applications by decision contexts in Europe JF - Regional environmental change N2 - Sociocultural valuation (SCV) of ecosystem services (ES) discloses the principles, importance or preferences expressed by people towards nature. Although ES research has increasingly addressed sociocultural values in past years, little effort has been made to systematically review the components of sociocultural valuation applications for different decision contexts (i.e. awareness raising, accounting, priority setting, litigation and instrument design). In this analysis, we investigate the characteristics of 48 different sociocultural valuation applications—characterised by unique combinations of decision context, methods, data collection formats and participants—across ten European case studies. Our findings show that raising awareness for the sociocultural value of ES by capturing people’s perspective and establishing the status quo, was found the most frequent decision context in case studies, followed by priority setting and instrument development. Accounting and litigation issues were not addressed in any of the applications. We reveal that applications for particular decision contexts are methodologically similar, and that decision contexts determine the choice of methods, data collection formats and participants involved. Therefore, we conclude that understanding the decision context is a critical first step to designing and carrying out fit-for-purpose sociocultural valuation of ES in operational ecosystem management.

Herein, we provide evidence that the immunosuppressive phenotype of TAMs is controlled by long-chain fatty acid metabolism, specifically unsaturated fatty acids, here exemplified by oleate. Consequently, en-route enriched lipid droplets were identified as essential organelles, which represent effective targets for chemical inhibitors to block in vitro polarization of TAMs and tumor growth in vivo. In line, analysis of human tumors revealed that myeloid cells infiltrating colon cancer but not gastric cancer tissue indeed accumulate lipid droplets. Mechanistically, our data indicate that oleate-induced polarization of myeloid cells depends on the mammalian target of the rapamycin pathway. Thus, our findings reveal an alternative therapeutic strategy by targeting the pro-tumoral myeloid cells on a metabolic level.

Noch sieht die Realität allerdings anders aus. Wie Ehemalige sich zwischen familiären und beruflichen Optionen entschieden haben, welche Probleme sie zu bewältigen hatten und welche Lösungen sie fanden, davon berichten sie in unserem Titelthema. Jede dritte Akademikerin bleibt heute in Deutschland kinderlos, Tendenz steigend. Abgesehen davon, dass es auch schlichtweg Lebensentwürfe ohne Kinder gibt: Ein nicht unwesentlicher Grund dafur ist sicherlich, dass die größte Last bei der Kindererziehung immer noch Frauen tragen und sie deshalb auch die größeren Einbußen in ihrer Karriere haben. So herrscht bei vielen Arbeitgebern das Vorurteil, Mütter in Führungspositionen wären weniger leistungsfahig. Dass aber gerade eine Familie Frauen in verantwortungsvollen Positionen den Rücken stärken und zu noch größerem Einsatz beflügeln kann, davon berichtet der einführende Artikel. Ein Beispiel dafür, dass sich Familie und eine berufliche Führungsposition vereinbaren lassen, ist auch Uni-Präsidentin, Prof. Dr.-Ing. Dr. Sabine Kunst. In einem Interview verrät sie ihr ganz persönliches Erfolgsrezept und stellt außerdem die strategische Ausrichtung der Hochschule in den nächsten Jahren vor. Wenn Sie Ihre Erfahrungen zu unserem Titelthema mit anderen Ehemaligen diskutieren wollen, können Sie dies unter .. Forum" in unserem "alumni-portal" tun. Wie immer freuen wir uns auf Ihre Meinung zur vorliegenden Ausgabe von ,,Portal alurnni" und wünschen Ihnen viele Vergnügen beim Lesen. Viele Grüße aus Potsdam, Ihr Alumni-Team. N2 - Dear readers, if the Federal Ministry for Family Affairs has its way, then Germany should become one ofthe most family friendly countries in Europe. However, today's reality shows a much different picture. ln our cover story, alumni report on how they have decided between familial and professional options as weil as on the problems solved along the way, and those yet to be mastered. One-third of all warnen with academic degrees do not have children. Not disregarding that there are paths in life which simply do not include having children, an important reason for this tendency lies without doubt in the fact that warnen still continue to carry the largest burden in the childrearing process, and that they therefore experience more serious Iosses regarding their professional careers than their male counterparts. For example, bias against mothers in leadership positions, due to their supposed reduced productivity, is still widely held by employers. The main article of our cover story shows that it is especially the family which can support warnen in positions of responsibility. The university's president, Prof Dr.-lng. Dr. Sabine Kunst, provides us with one prominent example of the compatibility offamily and a professionalleadership position. ln an intenview she reveals her personal recipe for success - and discusses the strategic development of the university in the years to come. lf you would like to discuss your experiences regarding family and professionallife with other alumni, please feel free to do so in the "forum" on our "alumni-portal". As always, we hope you enjoy reading this issue of the "Portal alumni" and appreciate your feedback. With best regards from Potsdam, Your Alumni Team.

Commonly, small overlapping peptides are chemically synthesized and immobilized to determine the specific peptide sequence. In this study, we report the use of a fast and inexpensive planar microbead chip for epitope mapping. We developed a generic strategy for expressing recombinant peptide libraries instead of using expensive synthetic peptide libraries. A biotin moiety was introduced in vivo at a defined peptide position using biotin ligase. Peptides in crude Escherichia coli lysate were coupled onto streptavidin-coated microbeads by incubation, thereby avoiding tedious purification procedures. For read-out we used a multiplex planar microbead chip with size- and fluorescence-encoded microbead populations. For epitope mapping, up to 18 populations of peptide-loaded microbeads (at least 20 microbeads per peptide) displaying the primary sequence of a protein were analyzed simultaneously. If an epitope was recognized by an antibody, a secondary fluorescence-labeled antibody generated a signal that was quantified, and the mean value of all microbeads in the population was calculated. We mapped the epitopes for rabbit anti-PA28 gamma (proteasome activator 28 gamma) polyclonal serum, for a murine monoclonal antibody against PA28 gamma, and for a murine monoclonal antibody against the hamster polyoma virus major capsid protein VP1 as models. In each case, the identification of one distinct peptide sequence out of up to 18 sequences was possible. Using this approach, an epitope can be mapped multiparametrically within three weeks.

A1 - Ruehl, Ralph T1 - CYP26A1-specific antagonist influence on embryonic implantation, gene expression and endogenous retinoid concentration in rats N2 - Retinoids are essential in vertebrate reproduction and embryonic development. All-trans-retinoic acid (ATRA) is tightly regulated during these processes. CYP26A1 is mainly responsible for its degradation. To study the role of CYP26A1 during implantation, we applied R115866, a CYP26A1-specific antagonist, to rats during early gestation days (GD). On GD 6.5 and 12 samples were collected and the number of embryos was evaluated. ATRA concentration increased in uterus and serum, mRNA expression of CYP26A1 and CRABP2 increased in the liver, but not in the uterus. Uterine COX1 and 17 beta HSD mRNA expression was decreased. The number of embryos on GD 12 was not altered in this setting. It can be concluded that uterine expression of the analyzed retinoid-response genes during early gestation is not altered by this R115866 treatment and instead indirectly via ATRA. From our experiment we cannot confirm that ATRA obtains a major influencing role in the regulation of embryonic implantation.

The suggested approach offers multi-level analytical access, it centers around interactionist conceptions and knowledge discourses. The conceptual framework we suggest is spelled out in terms of how to observe and being sensitive of (re-)production of power structures inside the courtroom as well as in regard to relations imported into the courtroom. For this purpose, we integrate (i) the micro-level of courtroom interactions and (ii) (self-)presentation, (iii) the meso-level of knowledge (re)production and the establishment of knowledge orders and (iv) an intersectional perspective on gender, race, and class in knowledge discourses. By applying a multi-level approach, we open up new explanatory avenues to understand the constitution of terrorism as a socio-legal object. The methodical framework connects hitherto unconnected elements, that is, participants' interactions and negotiation, their (self-)representations, ascriptions and narrative performances, and knowledge (re-)production in order to establish or maintain political and social orders.

This ­volume comprises a collection of articles dedicated to Gisbert on the occasion of his 60th birthday, covering a range of topics from these areas and beyond. The contributions have in ­common that in a broad sense they have to do with language structures (and thus trees), and that in a more specific sense they have to do with birds. They thus cover two of Gisbert’s major interests in- and outside of the linguistic world (and ­perhaps even at the interface).

The resulting crystals were 20-300 mu m in size and displayed sector and growth zoning. Raman spectra were acquired at locations in the sample for which preceding electron microprobe (EMP) analyses revealed sufficient compositional homogeneity. The dataset documents shifts of Raman bands with changing composition. In this study, bands that have previously not been reported were found for the intermediate compositions and for pure hafnon, in particular at wavenumbers less than 200 cm(-1). For these external modes, the dataset provides new insight into the compositional dependence of their frequencies. Density-functional theory calculations support the observations and are used for a detailed interpretation of the spectra. The pitfalls of the EMP analysis along the zircon-hafnon join are highlighted.
