The relationship between nature connectedness and eudaimonic well-being: A meta-analysis

Nature connectedness relates to an individual’s subjective sense of their relationship with the natural world. A recent meta-analysis has found that people who are more connected to nature also tend to have higher levels of self-reported hedonic well-being; however, no reviews have focussed on nature connection and eudaimonic well-being. This meta-analysis was undertaken to explore the relationship of nature connection with eudaimonic well-being and to test the hypothesis that this relationship is stronger than that of nature connection and hedonic well-being. From 20 samples (n = 4758), a small significant effect size was found for the relationship of nature connection and eudaimonic well-being (r = 0.24); there was no significant difference between this and the effect size (from 30 samples n = 11638) for hedonic well-being (r = 0.20). Of the eudaimonic well-being subscales, personal growth had a moderate effect size which was significantly larger than the effect sizes for autonomy, purpose in life/meaning, self-acceptance, positive relations with others and environmental mastery, but not vitality. Thus, individuals who are more connected to nature tend to have greater eudaimonic well-being, and in particular have higher levels of self-reported personal growth.University of Derb

Hidden in Plain Sight-An analysis of the influence of strategic leadership characteristics and styles of the Chair, Chair/CEO, CEO and CFO in banking failure, recapitalisation or bailout (1999-2017). A grounded theory approach

The global financial crisis (2007-2009) caused the most severe global economic downturn since the Great Depression and in the 10 years since, the global banking sector has witnessed an onslaught of banking scandals such as: LIBOR, FOREX, money laundering, and tax avoidance. In the wake of these ongoing issues, there is a clear need to explore alternative methods to tackle failures and scandals in the banking sector. A key weakness in the current discourse is the lack of analysis of the leadership characteristics and styles of board members of leading banks. This study responds to this weakness, contributing in three principle ways. Firstly, by extending the use of grounded theory, it investigates the leadership characteristics and styles of the Chair, Chair/CEO, CEO and CFO in the 30 largest banks by market capitalisation with autonomous boards (taken from the Banker Top 1000 banks 2017), and those of the 17 largest banks by market capitalisation that failed, needed recapitalisation or bailout (1999 – 2017) and presents a substantive theory of ‘Strategic Leadership Influence in Banking’. Secondly, it adds to the strategic leadership debate finding successful leaders exhibit characteristics and traits of more than one leadership style. Thirdly, the research adds to the conversation on shared leadership by analysing the relationship between the Chair, Chair/CEO, CEO and CFO, which is found to be an influencing factor in banking failure, recapitalisation or bailout. In highlighting the influence of leadership characteristics and styles in banking failure, the research also provides a useful risk analysis tool for policy makers and regulators as they attempt to avoid future banking collapses

Understanding walking and cycling:summary of key findings and recommendations

It is widely recognized that there is a need to increase levels of active and sustainable travel in British urban areas. The Understanding Walking and Cycling (UWAC) project, funded by the EPSRC, has examined the factors influencing everyday travel decisions and proposes a series of policy measures to increase levels of walking and cycling for short trips in urban areas. A wide range of both quantitative and qualitative data were collected in four English towns (Lancaster, Leeds, Leicester and Worcester), including a questionnaire survey, spatial analysis of the built environment, interviews (static and whilst mobile) and detailed ethnographies. Key findings of the research are that whilst attitudes to walking and cycling are mostly positive or neutral, many people who would like to engage in more active travel fail to do so due to a combination of factors. These can be summarised as: Concerns about the physical environment, especially with regard to safety when walking or cycling; The difficulty of fitting walking and cycling into complex household routines (especially with young children); The perception that walking and cycling are in some ways abnormal things to do. It is suggested that policies to increase levels of walking and cycling should focus not only on improving infrastructure (for instance through fully segregated cycle routes along main roads and restriction on vehicle speeds), but also must tackle broader social, economic, cultural and legal factors that currently inhibit walking and cycling. Together, such changes can create an environment in which driving for short trips in urban areas is seen as abnormal and walking or cycling seem the obvious choices.

Measuring storage and loss moduli using optical tweezers: broadband microrheology

We present an experimental procedure to perform broadband microrheological measurements with optical tweezers. A generalised Langevin equation is adopted to relate the time-dependent trajectory of a particle in an imposed flow to the frequency-dependent moduli of the complex fluid. This procedure allows us to measure the material linear viscoelastic properties across the widest frequency range achievable with optical tweezers.Comment: 5 pages, 3 figure

Long-term culture of SH-SY5Y neuroblastoma cells in the absence of neurotrophins : a novel model of neuronal ageing

LS is sponsored by a Wellcome Trust ISSF studentship and YC is a recipient of a China Scholarship Council award.Background Studying human ageing is of increasing importance due to the worldwide ageing population. However, it faces the challenge of lengthy experiments to produce an ageing phenotype. Often, to recreate the hallmarks of ageing requires complex empirical conditions that can confound data interpretation. Indeed, many studies use whole organisms with relatively short life spans, which may have little, or limited, relevance to human ageing. There has been extensive use of cell lines to study ageing in human somatic cells, but the modelling of human neuronal ageing is somewhat more complex in vitro. New Method We cultured the well-characterised SH-SY5Y human neural cell line to produce high purity cultures of cells differentiated to express a neuronal phenotype, and designed a protocol to maintain these cells in culture until they accumulated biomarkers of cellular ageing. Results Our data validate a novel and simple technique for the efficient differentiation and long-term maintenance of SH-SY5Y cells, expressing markers of neuronal differentiation and demonstrating electrical activity in culture. Over time in vitro, these cells progressively accumulate markers of ageing such as enhanced production of reactive oxygen species and accumulation of oxidative damage. Comparison to Existing Methods In comparison to existing techniques to model neuronal ageing our method is cost effective, requiring no specialist equipment or growth factors. Conclusions We demonstrate that SH-SY5Y cells, grown under these culture conditions, represent a simple model of neuronal ageing that is amenable to cell biological, biochemical and electrophysiological investigation.Publisher PDFPeer reviewe

Securing tropical forest carbon: the contribution of protected areas to REDD

Forest loss and degradation in the tropics contribute 6-17% of all greenhouse gas emissions. Protected areas cover 217.2 million ha (19.6%) of the world's humid tropical forests and contain c. 70.3 petagrams of carbon (Pg C) in biomass and soil to 1 m depth. Between 2000 and 2005, we estimate that 1.75 million ha of forest were lost from protected areas in humid tropical forests, causing the emission of 0.25-0.33 Pg C. Protected areas lost about half as much carbon as the same area of unprotected forest. We estimate that the reduction of these carbon emissions from ongoing deforestation in protected sites in humid tropical forests could be valued at USD 6,200-7,400 million depending on the land use after clearance. This is >1.5 times the estimated spending on protected area management in these regions. Improving management of protected areas to retain forest cover better may be an important, although certainly not sufficient, component of an overall strategy for reducing emissions from deforestation and forest degradation (REDD

Developing pathways to low carbon land based passenger transport in Great Britain by 2050

The key aim of this paper is to examine strategic pathways to low carbon personal transport in Britain and to compare these with the current trajectory of transport policy. A 2050 baseline was established using trend information, forecasts and best evidence from the literature on response to policy intervention. A range of strategies are tested including: technological development, pricing, public transport and soft measures. We conclude that even dramatic technological advance cannot meet the more stringent targets for carbon reduction in the absence of considerable behavioural change. The most promising combinations of measures involve clear price signals to encourage both a reduction in the use of motorised transport and the development and purchase of more efficient vehicles; decarbonisation of public transport and facilitating measures to enhance access whilst reducing the need for motorised travel

What is a sustainable level of CO2 emissions from transport activity in the UK?

The paper reports on the development of UK transport targets for CO2 emissions for 2050. Five key studies containing future carbon emissions scenarios for the UK were used to establish targets for overall reductions in emissions to achieve stabilisation at 550 ppm and 450 ppm of atmospheric CO2. Two approaches were used to consider the proportion of total emissions that would be attributable to transport in the future: 26% of total emissions as now and an increase to 41% of total emissions in line with forecasts. The overall targets and expected contributions from transport were used to derive target emissions for the transport sector to be achieved by 2050, which ranged from 8.2 MtC to 25.8 MtC. Even the weakest of these targets represents a considerable reduction from current emissions levels
