Integrating beneficiaries into assessment of ecosystem services from managed forests at the Hubbard Brook Experimental Forest,USA

Background：Forests contribute to human wellbeing through the provision of important ecosystem services.Methods：In this study,we investigated how the perceived importance of ecosystem services may impact the overall benefit provided by managed watersheds at the Hubbard Brook Experimental Forest over a 45-year period,using standardized measures of service capacity weighted by service importance weights derived from a survey of beneficiaries.Results：The capacity of watersheds to regulate water flow and quality was high in all watersheds throughout the study period,whereas cultural services such as scenic beauty declined after harvest.Impacts on greenhouse gas regulation depended on the efficiency with which harvested biomass was used.Surveys revealed that stakeholders placed high value on all ecosystem services,with regulating and cultural services seen as more important than provisioning services.When service metrics were weighted by survey responses and aggregated into a single measure,total service provision followed the same overall trend as greenhouse gas regulation.Where biomass use was less efficient in terms of greenhouse gas emissions,harvesting resulted in an overall ＂ecosystem service debt＂;where use was more efficient,this ＂ecosystem service debt＂ was reduced.Beneficiaries＇ educational backgrounds significantly affected overall assessment of service provision.Beneficiaries with college or university degrees incurred smaller ＂ecosystem service debts＂ and were less negatively affected by harvesting overall.Conclusions：This study highlights the importance of including empirical measures of beneficiary preference when attempting to quantify overall provision of ecosystem services to human beneficiaries over time.

Affect regulation in psychoanalytic treatments of patients with a borderline personality disorder–psychoanalysis and psychodynamic psychotherapy–a comparison

BACKGROUND A recent meta-analysis has confirmed that the effects of psychotherapy on patients with borderline personality disorders(BPD)are still insufficiently understood.Evidence of differences between different types of therapies has been questioned.AIM To study repetitive interaction patterns in patients with BPD undergoing either psychoanalysis or psychodynamic therapy.METHODS Psychoanalysis(PSA)or psychodynamic psychotherapy(PDT)was administered to 10 patients each,the two groups were matched.Therapy regimens were applied according to care as usual/manualized including quality control and supervision as usual.Randomization to one of the groups was done after baseline assessment.During classical PSA(n=10)and PDT(n=10),semiannually,recordings(audio or video)of five consecutive therapy sessions were taken over three years for an ex-post analysis.The patients'characteristics,such as affect parameters[Affect regulation and experience Q-sort(AREQ)],quality of object relations(quality of object relations scale)and personality traits[Shedler-Westen Assessment Procedure(SWAP-200)]were analyzed retrospectively by independent raters.Therapeutic action(psychotherapy process Q-sort)and affective(re)actions of the patients(AREQ)were then analyzed in relation to changes found in the patients'characteristics.RESULTS During the first year of therapy(PSA:n=10;PDT:n=9),the therapeutic method PSA was associated with significant improvements in the variable"SWAP Borderline",while in PDT change was not significantly different to baseline(PSA:P=0.04;PDT:P=0.33).Long-term results and follow up was available for seven participants in PSA and for five in PDT after three years;change in SWAP borderline for the whole sample was not significant at this time point when confronting to baseline(P=0.545).However,differences between PSA and PDT were significant when analyzing the“mean change”in the SWAP Borderline variable after one year of therapy(P=0.024):PSA led to slightly increased BPD symptoms,while PDT to a decrease;for the long run,variance of observed change was higher in PSA than in PDT(SDPSA±9.29 vs SDPDT±7.94).Our assumption that transference interpretations,closely followed by affective changes in the patient,could be useful modes of interaction was reproducible in our findings,especially when looking at the descriptive findings in the long-term data.The analysis of repetitive interaction structures demonstrated a very specific"time-lag"between therapeutic intervention and a corresponding increase in positive affect in successful therapy cases.CONCLUSION Exploring the change processes in the patients'characteristics and linking these changes to specific treatment strategies is of clinical importance when starting treatment and for its long-term progress.

NDGA ameliorates experimental autoimmune encephalomyelitis via the regulation of IL-6,IL-17 and TGF-b

Objective To investigate the effets of nordihydroguaiaretic acid(NDGA)on the expression of IL-6,IL-17and TGF-βin mice with experimental autoimmune encephalomyelitis(EAE).Methods C57BL/6 mice were immunized with MOG35-55 to induce EAE.The 54 mice were randomly and equally divided into control group,model group and treatment group.Mice in treatment
