    Background: Persistent pain in breast cancer survivors is common. Psychological and sleep-related factors modulate perception, interpretation and coping with pain and may contribute to the clinical phenotype. The present analysis pursued the hypothesis that breast cancer survivors form subgroups, based on psychological and sleep-related parameters that are relevant to the impact of pain on the patients' life. Methods: We analysed 337 women treated for breast cancer, in whom psychological and sleep-related parameters as well as parameters related to pain intensity and interference had been acquired. Data were analysed by using supervised and unsupervised machine-learning techniques (i) to detect patient subgroups based on the pattern of psychological or sleep-related parameters, (ii) to interpret the detected cluster structure and (iii) to relate this data structure to pain interference and impact on life. Results: Artificial intelligence-based detection of data structure, implemented as self-organizing neuronal maps, identified two different clusters of patients. A smaller cluster (11.5% of the patients) had comparatively lower resilience, more depressive symptoms and lower extraversion than the other patients. In these patients, life-satisfaction, mood, and life in general were comparatively more impeded by persistent pain. Conclusions: The results support the initial hypothesis that psychological and sleep-related parameter patterns are meaningful for subgrouping patients with respect to how persistent pain after breast cancer treatments interferes with their life. This indicates that management of pain should address more complex features than just pain intensity. Artificial intelligence is a useful tool in the identification of subgroups of patients based on psychological factors. (C) 2020 The Authors. Published by Elsevier Ltd.

    Species living in metapopulations depend on connected habitat networks for their survival. If habitat networks experience fast temporal dynamics, species conservation requires preventing habitat discontinuities that could lead to metapopulation extinctions. However, few institutional solutions exist for the maintenance of spatiotemporally dynamic habitat networks outside of protected areas. To explore this often neglected problem, we studied the institutional fit of false heath fritillary (Melitaea diamina) conservation in Finland from the perspective of conservation institutions' ability to manage early successional habitat availability for this endangered species. We identified four institutional arrangements that enable effective conservation management of dynamic habitat networks: (1) acknowledgment of habitat dynamics, (2) monitoring of and responding to changes in the habitat network, (3) management of resources for fluctuating resource needs, and (4) scaling of activities through flexible collaborations. These arrangements provide the institutional flexibility needed for responding to temporal changes in habitat availability.

    Background: Millions of children worldwide suffer from posttraumatic stress disorder (PTSD) symptoms and other mental health problems due to repeated exposure to war or organized violence. Forms of cognitive-behavioral therapy (CBT) are the most commonly used treatment for PTSD and appear to be effective for children as well, but little is known about the mechanisms of change through which they achieve their effectiveness. Here we present the study protocol of a randomized controlled trial (RCT) studying the effectiveness and mechanisms of change of Narrative Exposure Therapy (NET), a CBT-based, manualized, short-term intervention for PTSD symptoms resulting from repeated traumatization, in immigrant children traumatized by war. Methods/Design: We are conducting a multicentre, pragmatic RCT in a usual care setting. Up to 80 9-17-year-old immigrant children who have experienced war and suffer from PTSD symptoms will be randomized into intervention (NET) and control (treatment as usual, TAU) groups of equal sizes. The effectiveness of NET treatment will be compared to both a waiting list and the parallel TAU positive control group, on the primary outcomes of PTSD and depressive symptoms, psychological distress, resilience, and level of cognitive performance. The effects of the intervention on traumatic memories and posttraumatic cognitions will be studied as potential mechanisms of change mediating overall treatment effectiveness. The possible moderating effects of peritraumatic dissociation, level of cognitive performance, and gender on treatment effectiveness will also be considered. We hypothesize that NET will be more effective than a waitlist condition or TAU in reducing PTSD and other symptoms and improving resilience, and that these effects will be mediated by changes in traumatic memories and posttraumatic cognitions. Discussion: The results of this trial will provide evidence for the effectiveness of NET in treating trauma-related symptoms in immigrant children affected by war. The trial will also generate insights into the complex relationships between PTSD, memory functions, posttraumatic cognitions and cognitive performance in children, and help guide the future development and implementation of therapeutic interventions for PTSD in children.

    Agriculture affects biodiversity on a global scale and especially in the Neotropics, leading to land-management challenges in which native wildlife is forced to interact with high-contrast landscape matrices. Further, the direct and indirect effects of hurricanes impacting native habitat in human-modified landscapes increases reliance on agricultural areas and high-contrast matrices. To understand how avian communities in a human-modified landscape respond to hurricane disturbance, we evaluated post-hurricane trends in species richness, density, structure, and functional and taxonomic composition in avian communities at tropical dry forest and in three agricultural habitats using point-count surveys. We compared our results to a similar study that took place years before the hurricanes in the study area. Similar to pre-hurricane trends, tropical dry forest provided key habitat for endemic species relative to agricultural areas, and tree orchards continued to serve as key secondary habitat for a high species richness and community evenness. However, tree orchards, along with cattle pastures and crop fields, failed to serve as successful buffers of hurricane disturbance by supporting half the estimated bird density of tropical dry forest. Cattle pasture and crop fields were both relatively species poor and had low community evenness compared to tropical dry forest and tree orchards after the hurricanes. Tropical dry forest had distinct species and feeding guild compositions compared to the agricultural habitats. All habitat types after the hurricanes had higher numbers of granivores and a reduction of carnivores compared to pre-hurricane levels. Land management in the study landscape needs to incorporate strategies that raise the hurricane resilience of agricultural areas while providing resources to support higher species richness and density in agricultural systems. Such strategies include the preservation of native trees and shrubs and allowing for the natural succession of habitat in unused areas in tree orchards, cattle pasture, and crop fields.

    Although electroconvulsive therapy (ECT) is among the most effective treatment options for pharmacoresistant major depressive disorder (MDD), some patients still remain refractory to standard ECT practise. Thus, there is a need for markers reliably predicting ECT non/response. In our study, we have taken a novel translational approach for discovering potential biomarkers for the prediction of ECT response. Our hypothesis was that the promoter methylation of p11, a multifunctional protein involved in both depressive-like states and antidepressant treatment responses, is differently regulated in ECT responders vs. nonresponders and thus be a putative biomarker of ECT response. The chronic mild stress model of MDD was adapted with the aim to obtain rats that are resistant to conventional antidepressant drugs (citalopram). Subsequently, electroconvulsive stimulation (ECS) was used to select responders and nonresponders, and compare p11 expression and promoter methylation. In the rat experiments we found that the gene promoter methylation and expression of p11 significantly correlate with the antidepressant effect of ECS. Next, we investigated the predictive properties of p11 promoter methylation in two clinical cohorts of patients with pharmacoresistant MDD. In a proof-of-concept clinical trial in 11 patients with refractory MDD, higher p11 promoter methylation was found in responders to ECT. This finding was replicated in an independent sample of 65 patients with pharmacoresistant MDD. This translational study successfully validated the first biomarker reliably predicting the responsiveness to ECT. Prescreening of this biomarker could help to identify patients eligible for first-line ECT treatment and also help to develop novel antidepressant treatment procedures for depressed patients resistant to all currently approved antidepressant treatments.

    Sustainability science seeks to extend scientific investigation into domains characterized by a distinct problem-solving agenda, physical and social complexity, and complex moral and ethical landscapes. In this endeavor, it arguably pushes scientific investigation beyond its usual comfort zones, raising fundamental issues about how best to structure such investigation. Philosophers of science have long scrutinized the structure of science and scientific practices, and the conditions under which they operate effectively. We propose a critical engagement between sustainability scientists and philosophers of science with respect to how to engage in scientific activity in these complex domains. We identify specific issues philosophers of science raise concerning current sustainability science and the contributions philosophers can make to resolving them. In conclusion, we reflect on the steps philosophers of science could take to advance sustainability science.

    Biocultural diversity, which refers to the inextricable link between biodiversity and cultural diversity, has been predominantly associated with the traditional ways in which indigenous people in tropical countries interact with the natural environment. But it does not have to be restricted to these circumstances. Biocultural diversity may also be regarded as an interesting concept for understanding how people in industrialized and globalized societies deal with nature. This paper explores biocultural diversity in 20 European cities by considering (i) how biocultural diversity is interpreted in urban planning and governance, and (ii) what actual manifestations of biocultural diversity are present in these cities. Despite the fact that the concept of biocultural diversity was hardly recognized by city authorities, interviewees gave many examples of how biodiversity and cultural diversity are taken into account in (in) formal city policies. The research revealed two main manifestations of biocultural diversity within urban Europe: biocultural diversity grounded in ecological features, and cultural values as a basic foundation for biocultural diversity. Consequently, urban biocultural diversity was found to have two spatial levels: the city level and the site level. The former is the domain of governmental policy makers who discuss biocultural diversity in 'green space networks' in a rather static way. The latter is the domain where citizens participate in decisionmaking and the management of green spaces; it is here that cultural dynamics are most acknowledged.

    Purpose Psychosocial resources have been considered to be associated with survival among frail older adults but the evidence is scarce. The aim was to investigate whether psychosocial resources are related to survival among non-robust community-dwelling older people. Methods This is a prospective study with 10- and 18-year follow-ups. Participants were 909 non-robust (according to Rockwood's Frailty Index) older community-dwellers in Finland. Psychosocial resources were measured with living circumstances, education, satisfaction with friendship and life, visiting other people, being visited by other people, having someone to talk to, having someone who helps, self-rated health (SRH) and hopefulness about the future. To assess the association of psychosocial resources for survival, Cox regression analyses was used. Results Visiting other people more often than once a week compared to that of less than once a week (hazard ratio 0.61 [95% confidence interval 0.44-0.85], p = 0.003 in 10-year follow-up; 0.77 [0.62-0.95], p = 0.014 in 18-year follow-up) and good SRH compared to poor SRH (0.65 [0.44-0.97], p = 0.032; 0.68 [0.52-0.90], p = 0.007, respectively) were associated with better survival in both follow-ups. Visiting other people once a week (compared to that of less than once a week) (0.77 [0.62-0.95], p = 0.014) was only associated with better 18-year survival. Conclusions Psychosocial resources, such as regularly visiting other people and good self-rated health, seem to be associated with better survival among non-robust community-dwelling Finnish older people. This underlines the importance of focusing also on psychosocial well-being of frail older subjects to remain or promote their resilience. Key summary pointsAim To investigate whether psychosocial resources are associated with survival among non-robust community-dwelling older Finnish people during an 18-year follow-up. Findings Psychosocial resources, such as good self-rated health and regularly visiting other people, were significantly associated with better survival of non-robust older people. Message It is important to focus also on psychological well-being, together with physical activity and nutrition, of frail older people to remain or promoting their capacity.

    Contextualizing disciplinary histories through the personal stories of forerunners creates compelling narratives of the craft of evolving professions. By looking to our intellectual and practitioner ancestors, we participate in a dialogue with a history that shapes our contemporary professional identities and aspirations for the future. Grounded in a decolonizing approach to social work, this article examines how the discipline shapes its professional identity and ways of knowing by centering the role of canonical founders in the social work curriculum. The global social work origin story in the curriculum often centers on Anglo-American ancestors that illustrate the development of the disciplinary boundaries of the international profession. One method of decolonizing social work epistemology at the intersection of ancestors and professional lineage could be to look to public history as a pedagogical tool in the curriculum. The article concludes by examining the use of podcasts as having the potential to decolonize the process of collecting, analyzing, and disseminating local knowledge of ancestors thus challenging the top-down approach to expert-driven epistemologies.

    The response of an ecosystem to external drivers may not always be gradual and reversible. Discontinuous and sometimes irreversible changes, called 'regime shifts' or 'Critical transitions', can occur. The likelihood of such shifts is expected to increase for a variety of ecosystems, and it is difficult to predict how close an ecosystem is to a critical transition. Recent modelling studies identified indicators of impending regime shifts that can be used to provide early warning signals of a critical transition. The identification of such transitions crucially depends on the ability to monitor key ecosystem variables, and their success may be limited by lack of appropriate data. Moreover, empirical demonstrations of the actual functioning of these indicators in real-world ecosystems are rare. This paper presents the first study which uses remote sensing data to identify a critical transition in a wetland ecosystem. In this study, we argue that a time series of remote sensing data can help to characterize and determine the timing of a critical transition. This can enhance our abilities to detect and anticipate them. We explored the potentials of remotely sensed vegetation (NDVI), water (MNDWI), and vegetation- water (VWR) indices, obtained from time series of MODIS satellite images to characterize the stability of a wetland ecosystem, Dorge Sangi, near the lake Urmia, Iran, that experienced a regime shift recently. In addition, as a control case, we applied the same methods to another wetland ecosystem in Lake Arpi, Armenia which did not experience a regime shift. We propose a new composite index (MVWR) based on combining vegetation and water indices, which can improve the ability to anticipate a critical transition in a wetland ecosystem. Our results revealed that MVWR in combination with autocorrelation at-lag-1 could successfully provide early warning signals for a critical transition in a wetland ecosystem, and showed a significantly improved performance compared to either vegetation (NDVI) or water (MNDWI) indices alone.

    Although sustainability science and social-ecological systems research pursue very similar goals, i.e., generate problem- and solution-oriented knowledge to foster sustainability transformation, they partly apply different research approaches and use different key concepts. Our aim is to identify archetypes of sustainability transformation research derived for sustainability science and social-ecological systems research that make knowledge from the two research pathways more accessible to each other in order to foster transformation. To reach this goal, we applied a mixed method approach toward an archetype analysis, based on semantic networks and clusters. Our findings point out that the fields of sustainability science and social-ecological systems research are rather coherent and not so distinct as may be expected, especially in terms of normative goals and addressed topics. Our analysis inductively reveals four archetypes of sustainability transformation research, with thematic structures clustered around (1) environmental change and ecosystem services; (2) resilience and vulnerability; (3) knowledge production for sustainability; and (4) governance for sustainability. We describe how these archetypes interact and facilitate dialogue between the fields. When considering the two transformation research pathways from the perspective of the research mode of transdisciplinary research, their discourses appear more disconnected. To fill this gap, we uncover key concepts that can strengthen the connection of the two fields to inform and foster sustainability transformations. These concepts involve engaging with nonacademic actors and seeking impact in policy.

    Context Most protected areas are managed based on objectives related to scientific ecological knowledge of species and ecosystems. However, a core principle of sustainability science is that understanding and including local ecological knowledge, perceptions of ecosystem service provision and landscape vulnerability will improve sustainability and resilience of social-ecological systems. Here, we take up these assumptions in the context of protected areas to provide insight on the effectiveness of nature protection goals, particularly in highly human-influenced landscapes. Objectives We examined how residents' ecological knowledge systems, comprised of both local and scientific, mediated the relationship between their characteristics and a set of variables that represented perceptions of ecosystem services, landscape change, human-nature relationships, and impacts. Methods We administered a face-to-face survey to local residents in the Sierra de Guadarrama protected areas, Spain. We used bi- and multi-variate analysis, including partial least squares path modeling to test our hypotheses. Results Ecological knowledge systems were highly correlated and were instrumental in predicting perceptions of water-related ecosystem services, landscape change, increasing outdoors activities, and human-nature relationships. Engagement with nature, socio-demographics, trip characteristics, and a rural-urban gradient explained a high degree of variation in ecological knowledge. Bundles of perceived ecosystem services and impacts, in relation to ecological knowledge, emerged as social representation on how residents relate to, understand, and perceive landscapes. Conclusions Our findings provide insight into the interactions between ecological knowledge systems and their role in shaping perceptions of local communities about protected areas. These results are expected to inform protected area management and landscape sustainability.

    Hilsa fish (Tenualosa ilisha) have become an essential factor behind the well-being of the fishing community, giving fishers their identity as a source of cultural heritage. A field survey was conducted to understand the socio-economic conditions of hilsa fishers at the Meghna river estuary of Chandpur District using well-structured questionnaire interviews (N = 250) with hilsa fishers. The survey revealed that fishers' livelihoods and living conditions were still below average due to low literacy levels, lack of professional skills, and low incomes. More than two-thirds of the fishers were entirely dependent on hilsa fishing, while more than one-third had between 11 and 20 years of fishing experience. More than two-thirds of the fishers did not have an alternative occupation during ban periods, and the incentives provided by the government were not adequately received by half of the fishers. Fishers were divided into three groups according to their dependence on hilsa fishing. Significant differences were found between these groups in terms of the age of fishers, annual income from fishing, and annual fishing activity days. Therefore, the government, Fisheries cooperatives, NGOs, and other relevant organizations must unite to support fishers for sustainable hilsa fishery management.

    The present mixed-method longitudinal study examines students’ experiences of study-related exhaustion, regulation of learning, peer learning and peer support during university studies. At the first measurement point, 188 first-year students completed the questionnaire. At the second measurement point, 91 of the 188 students participated in the follow-up study at their fourth study year and completed the same questionnaire again. Of these, twelve students were interviewed. The results showed that experienced study-related exhaustion and self-regulation of content increased during studies. However, the results also showed a large individual variation in experienced study-related exhaustion. The students whose exhaustion decreased described experiences of peer support that helped them to develop their self-regulation skills. Students whose study-related exhaustion remained low evaluated their self-regulation skills as good. They experienced that they did not need other students’ support in the regulation of learning. The students whose study-related exhaustion increased or remained high described more problems in self-regulation. Most students relied on peer support because of self-regulation problems. However, not all students used other students’ support despite of problems in studying. It can be concluded that regulation skills have a key role in experienced study-related exhaustion during studies.

    Objective Peripartum depression (PPD) pertaining to depression in pregnancy and postpartum is one of the most common complications around childbirth with enduring adverse effects on mother and child health. Although psychiatric symptoms may improve or worsen over time, relatively little is known about the course of PPD symptoms and possible fluctuations Methods We applied a person-centered approach to examine PPD symptom patterns across pregnancy and childbirth. 824 women were assessed at three time points: first trimester (T1), third trimester (T2), and again at eight weeks (T3) postpartum. We assessed PPD symptoms, maternal mental health history, and childbirth variables Results Growth mixture modeling (GMM) analysis revealed four discrete PPD symptom trajectory classes including chronic PPD (1.1%), delayed (10.2%), recovered (7.2%), and resilient (81.5%). Delivery complications were associated with chronic PPD but also with the recovered PPD trajectory class. History of mental health disorders was associated with chronic PPD and the delayed PPD class Conclusion The findings underscore that significant changes in a woman’s depression level can occur across pregnancy and childbirth. While a minority of women experience chronic PDD, for others depression symptoms appear to significantly alleviate over time, suggesting a form of recovery. Our findings support a personalized medicine approach based on the woman’s symptom trajectory. Future research is warranted to identify the mechanisms underlying modifications in PPD symptoms severity and those implicated in recovery.

    Families mobilize psychosocial resources to attune negative consequences of economic hardship, but research is lacking among youth. We propose an Economic Stress Model in Emerging Adulthood (ESM-EA) conceptualizing age-salient social relationships and financial capability as mediators between economic hardship and well-being. The ESM-EA was tested in a three-wave prospective study following the 2008 economic recession, as part of the Finnish Educational Transitions studies. The sample consisted of 551 emerging adults (55.5% female) who participated at ages 23, 25, and 28. Economic pressures and financial capability mediated the effect of economic hardship on well-being, whereas social relationships did not. Individuals with an unfavorable financial situation at age 25 were more likely to show lower life satisfaction and higher depressive symptoms at 28 when they reported a higher level of economic pressures and a lower level of financial capability. Findings emphasize emerging adults' age-salient financial adjustments and management in enhancing well-being.

    Riparian forests have cool and humid microclimates, and one aim of leaving forested buffer strips between clear-cut areas and streams is to conserve these microclimatic conditions. We used an experimental study set up of 35 streamside sites to study the impacts of buffer strip width (15 or 30 m) and selective logging within the buffer strips on summer-time air temperature, relative air humidity and canopy openness 12 years after logging. The buffer strip treatments were compared to unlogged control sites. We found that 15-meter buffer strips with or without selective logging and 30-meter buffer strips with selective logging were insufficient in maintaining temperature, relative humidity and canopy openness at similar levels than they were in control sites. In contrast, 30-meter buffer strips differed only little from control sites, although they did have significantly lower mean air humidity. Microclimatic changes were increased by southern or southwestern aspect of the clear-cut, and by logging on the opposite side of the stream. We also tested how the cover of three indicator mosses (Hylocomium splendens, Pseudobqum cinclidioides and Polytrichum commune) had changed (from pre-logging to 12 years post-logging) in relation to post-logging air temperature, relative air humidity and canopy openness. We found that each of the species responded to at least one of these physical conditions. Air humidity was the most significant variable for explaining changes in the cover of the indicator moss species, suggesting that the changes in this microclimatic component has biological impacts. We conclude that to preserve riparian microclimatic conditions and species dependent on those, buffer strips should exceed 30 m in width, and not be selectively logged. Wider buffer strips are required if the clear-cut is towards south or southwest, or if the two sides of the stream are logged at the same time or during subsequent years.

    Despite the wide recognition that strongly interacting species can influence distributions of other species, species interactions are often disregarded when assessing or projecting biodiversity distributions. In particular, it remains largely uncharted the extent to which the disappearance of a keystone species cast repercussions in the species composition of future communities. We tested whether an avian top predator can exert both positive and negative effects on spatial distribution of other species, and if these effects persist even after the predator disappeared. We acquired bird count data at different distances from occupied and non-occupied nests of Northern goshawks Accipiter gentilis. Using a Bayesian joint species distribution model, we found that large bird species (preferred prey) are less abundant in the proximity of nests occupied by goshawks, whereas smaller species -expected to get protection from subordinate predators displaced by goshawks- more often showed an opposite association. These spatial differences level off gradually, but still persist for years after the goshawks have disappeared. This indicates that the composition of local bird populations and communities might be conditional on past species interactions. Therefore, endeavors centered around species distributions could largely benefit from acknowledging the local extinction of keystone species.

    This article introduces the concept of ‘threshold of adversity’ as an, at present, tentative means of understanding the turning points to radicalization and extremism within educational systems. The conceptual frame is, we argue, of pedagogical and policy relevance across and beyond Nordic countries. Across Nordic countries, then, the main objective for the prevention of radicalization and extremism through education (PVE-E) is to strengthen the students’ resilience against ideological influences. Given the specialist complexities of the interdisciplinary research literature on terrorism, from which much PVE-E derives, for teachers and policy-makers, understanding the theoretical contexts, which underlie such policy innovations and their pedagogical implementation, are, understandably, problematic. To discuss extremism and the possibilities of its prevention especially in the education sector, an understanding of what exactly is being prevented or fought against is needed. Our conceptual ‘threshold of adversity’ model offers at least a starting point for a more practicable pedagogical implementation.
