Fine-resolution mapping of microforms of a boreal bog using aerial images and waveform-recording LiDAR

Boreal bogs are important stores and sinks of atmospheric carbon whose surfaces are characterised by vegetation microforms. Efficient methods for monitoring their vegetation are needed because changes in vegetation composition lead to alteration in their function such as carbon gas exchange with the atmosphere. We investigated how airborne image and waveform-recording LiDAR data can be used for 3D mapping of microforms in an open bog which is a mosaic of pools, hummocks with a few stunted pines, hollows, intermediate surfaces and mud-bottom hollows. The proposed method operates on the bog surface, which is reconstructed using LiDAR. The vegetation was classified at 20 cm resolution. We hypothesised that LiDAR data describe surface topography, moisture and the presence and depth of field-layer vegetation and surface roughness; while multiple images capture the colours and texture of the vegetation, which are influenced by directional reflectance effects. We conclude that geometric LiDAR features are efficient predictors of microforms. LiDAR intensity and echo width were specific to moisture and surface roughness, respectively. Directional reflectance constituted 4-34 % of the variance in images and its form was linked to the presence of the field layer. Microform-specific directional reflectance patterns were deemed to be of marginal value in enhancing the classification, and RGB image features were inferior to LiDAR variables. Sensor fusion is an attractive option for fine-scale mapping of these habitats. We discuss the task and propose options for improving the methodology.Peer reviewe

Retirement as a predictor of physical functioning trajectories among older businessmen

Background Associations between retirement characteristics and consequent physical functioning (PF) are poorly understood, particularly in higher socioeconomic groups, where postponing retirement has had both positive and negative implications for PF. Methods Multiple assessments of PF, the first of which at the mean age of 73.3 years, were performed on 1709 men who were retired business executives and managers, using the RAND-36/SF-36 instrument, between 2000 and 2010. Questionnaire data on retirement age and type of pension was gathered in 2000. Five distinct PF trajectories were created using latent growth mixture modelling. Mortality- and covariate-adjusted multinomial regression models were used to estimate multinomial Odds Ratios (mOR) on the association between retirement characteristics and PF trajectories. Results A one-year increase in retirement age was associated with decreased likelihood of being classified in the 'consistently low' (fully adjusted mOR = 0.82; 95%CI = 0.70, 0.97; P = 0.007), 'intermediate and declining' (mOR = 0.89; 95%CI = 0.83, 0.96; P = 0.002), and 'high and declining' (mOR = 0.92; 95%CI = 0.87, 0.98; P = 0.006) trajectories, relative to the 'intact' PF trajectory. Compared to old age pensioners, disability pensioners were more likely to be classified in the 'consistently low' (mOR = 23.77; 95% CI 2.13, 265.04; P = 0.010), 'intermediate and declining' (mOR = 8.24; 95%CI = 2.58, 26.35; P < 0.001), and 'high and declining' (mOR = 2.71; 95%CI = 1.17, 6.28; P = 0.020) PF trajectories, relative to the 'intact' PF trajectory. Conclusions Among executives and managers, older age at retirement was associated with better trajectories of PF in old age. Compared to old age pensioners, those transitioning into disability and early old age pensions were at risk of having consistently lower PF in old age.Peer reviewe

Retirement age and type as predictors of frailty : a retrospective cohort study of older businessmen

Objectives To study the association between retirement characteristics and frailty in a homogenous population of former business executives. Design Cross-sectional cohort study using data from the Helsinki Businessmen Study. Setting Helsinki, Finland. Participants 1324 Caucasian men, born in 1919-1934, who had worked as business executives and managers and of whom 95.9% had retired by the year 2000. Questions on age at and type of retirement, lifestyle and chronic conditions were embedded in questionnaires. Primary and secondary outcome measures Frailty assessed according to a modified phenotype definition at mean age 73.3 years. Results Mean age at retirement was 61.3 years (SD 4.3) and 37.1% had retired due to old age. The prevalence of frailty was lowest among men retiring at ages 66-67 years but increased among those who worked up to age 70 years or older. Compared with men who retired before age 55 years, those retiring at ages 58-69 years were at decreased risk of frailty in old age relative to non-frailty (adjusted ORs 0.07-0.29, pPeer reviewe

Learning how to understand complexity and deal with sustainability challenges : A framework for a comprehensive approach and its application in university education

Sustainability challenges such as climate change, biodiversity loss, poverty and rapid urbanization are complex and strongly interrelated. In order to successfully deal with these challenges, we need comprehensive approaches that integrate knowledge from multiple disciplines and perspectives and emphasize interconnections. In short, they aid in observing matters in a wider perspective without losing an understanding of the details. In order to teach and learn a comprehensive approach, we need to better understand what comprehensive thinking actually is. In this paper, we present a conceptual framework for a comprehensive approach, termed the GHH framework. The framework comprises three dimensions: generalism, holism, and holarchism. It contributes to the academic community's understanding of comprehensive thinking and it can be used for integrating comprehensive thinking into education. Also, practical examples of the application of the framework in university teaching are presented. We argue that an ideal approach to sustainability challenges and complexity in general is a balanced, dialectical combination of comprehensive and differentiative approaches. The current dominance of specialization, or the differentiative approach, in university education calls for a stronger emphasis on comprehensive thinking skills. Comprehensiveness should not be considered as a flawed approach, but should instead be considered as important an aspect in education as specialized and differentiative skills. (C) 2017 Elsevier B.V.

Stories of self, us, and now: narrative and power for health equity in grassroots community organizing

IntroductionCommunity organizing initiatives, which build power through cycles of listening, participatory research, collective action, and reflection, have demonstrated the capacity to intervene on, complicate, and resist dominant societal narratives while promoting alternative public narratives focused on shared values and hope for a better future.MethodsTo explore processes of public narrative change and their relationship to community and organizational empowerment, we interviewed 35 key leaders in community organizing initiatives in Detroit, MI and Cincinnati, OH about how narrative change takes place within community organizing practices.ResultsLeaders’ perspectives revealed crucial roles for narrative and storytelling in guiding individual and collective behavior, supporting the development of relationships of trust and accountability, and linking personal and collective experiences to pressing social issues.DiscussionFindings from this study indicate that systemic change is a labor-intensive process and one that requires the development of leaders (stories of self) and the cultivation of collective structures (stories of us) capable of enacting power to effect change with urgency (stories of now). We conclude by discussing implications of these findings for public narrative interventions and related health equity promotion efforts

Midlife Cardiovascular Status and Old Age Physical Functioning Trajectories in Older Businessmen

OBJECTIVES: The associations between cardiovascular disease (CVD) risk and later physical functioning have been observed, but only a few studies with follow-up into old age are available. We investigated the association between cardiovascular status in midlife and physical functioning trajectories in old age. DESIGN: Prospective cohort study. SETTING: Helsinki Businessmen Study. PARTICIPANTS: We studied white men born between 1919 and 1934 in the Helsinki Businessmen Study (HBS, initial n = 3490). MEASUREMENTS: Three CVD status groups were formed based on clinical measurements carried out in 1974: signs of CVD (diagnosed clinically or with changes in ECG, chronic disease present or used medication, n = 563); healthy and low CVD risk (n = 593) and high CVD risk (n = 1222). Of them, 1560 men had data on physical functioning from at least one of four data collection waves between 2000-2010. Ten questions from the RAND-36 (SF-36) survey were used to construct physical functioning trajectories with latent class growth mixture models. Mortality was accounted for in competing risk models. RESULTS: A five-class solution provided the optimal number of trajectories: “intact,” “high stable,” “high and declining,” “intermediate and declining,” and “consistently low” functioning. Compared with low CVD risk, high CVD risk in midlife decreased the risk of being classified into the intact (fully adjusted β = −3.98; standard error = 2.0; P =.046) relative to the consistently low physical functioning trajectory. Compared with low CVD risk, those with signs of CVD were less likely to follow the intact, high stable, or high and declining relative to the consistently low trajectory (all P CONCLUSION: Among businessmen, a more favorable CVD profile in midlife was associated with better development of physical functioning in old age.</p

Population change in breeding boreal waterbirds in a 25-year perspective : What characterises winners and losers?

Understanding drivers of variation and trends in biodiversity change is a general scientific challenge, but also crucial for conservation and management. Previous research shows that patterns of increase and decrease are not always consistent at different spatial scales, calling for approaches combining the latter. We here explore the idea that functional traits of species may help explaining divergent population trends. Complementing a previous community level study, we here analyse data about breeding waterbirds on 58 wetlands in boreal Fennoscandia, covering gradients in latitude as well as trophic status. We used linear mixed models to address how change in local abundance over 25 years in 25 waterbird species are associated with life history traits, diet, distribution, breeding phenology, and habitat affinity. Mean abundance increased in 10 species from 1990/1991 to 2016, whereas it decreased in 15 species. Local population increases were associated with species that are early breeders and have small clutches, an affinity for luxurious wetlands, an herbivorous diet, and a wide breeding range rather than a southern distribution. Local decreases, by contrast, were associated with species having large clutches and invertivorous diet, as well as being late breeders and less confined to luxurious wetlands. The three species occurring on the highest number of wetlands all decreased in mean abundance. The fact that early breeders have done better than late fits well with previous research about adaptability to climate change, that is, response to earlier springs. We found only limited support for the idea that life history traits are good predictors of wetland level population change. Instead, diet turned out to be a strong candidate for an important driver of population change, as supported by a general decrease of invertivores and a concomitant increase of large herbivores. In a wider perspective, future research needs to address whether population growth of large-bodied aquatic herbivores affects abundance of co-occurring invertivorous species, and if so, if this is due to habitat alteration, or to interference or exploitative competition.Peer reviewe

Added value of co-morbidity in predicting health-related quality of life in COPD patients

AbstractThe extent to which a chronic obstructive pulmonary disease (COPD) patient is impaired in health-related quality of life (HRQoL) is only to a small extent reflected in clinical and demographical measures. As the influence of co-morbidity on HRQoL is less clear, we investigated the added value of 23 common diseases in predicting HRQoL in COPD patients with mild to severe airways obstruction.COPD patients from general practice who appeared to have an forced expiratory volume in 1 sec/inspiratory vital capacity (FEV1/IVC) < predicted −1·64 SD, FEV1<80% predicted, FEV1reversibility <12% and a smoking history, were included (n=163). HRQoL was assessed with the short-form-36 (SF-36) and the presence of co-morbidity was determined by a questionnaire, which asked for 23 common diseases.All domains of the SF-36 were best predicted by the presence of three or more co-morbid diseases. FEV1% predicted, dyspnoea and the presence of one or two diseases were second-best predictors. Co-morbidity explained an additional part of the variance in HRQoL, particularly for emotional functioning (ΔR2=0·11). When individual diseases were investigated, only insomnia appeared to be related to HRQoL.As HRQoL is still only partly explained, co-morbidity and other patient characteristics do not clearly distinguish between COPD patients with severe impairments in HRQoL and COPD patients with minor or no impairments in HRQoL. Therefore, it remains important to ask for problems in daily functioning and well-being, rather than to rely on patient characteristics alone
