Likeability of Garden Birds: Importance of Species Knowledge & Richness in Connecting People to Nature.
This is the final version of the article. Available from Public Library of Science via the DOI in this record.Interacting with nature is widely recognised as providing many health and well-being benefits. As people live increasingly urbanised lifestyles, the provision of food for garden birds may create a vital link for connecting people to nature and enabling them to access these benefits. However, it is not clear which factors determine the pleasure that people receive from watching birds at their feeders. These may be dependent on the species that are present, the abundance of individuals and the species richness of birds around the feeders. We quantitatively surveyed urban households from towns in southern England to determine the factors that influence the likeability of 14 common garden bird species, and to assess whether people prefer to see a greater abundance of individuals or increased species richness at their feeders. There was substantial variation in likeability across species, with songbirds being preferred over non-songbirds. Species likeability increased for people who fed birds regularly and who could name the species. We found a strong correlation between the number of species that a person could correctly identify and how connected to nature they felt when they watched garden birds. Species richness was preferred over a greater number of individuals of the same species. Although we do not show causation this study suggests that it is possible to increase the well-being benefits that people gain from watching birds at their feeders. This could be done first through a human to bird approach by encouraging regular interactions between people and their garden birds, such as through learning the species names and providing food. Second, it could be achieved through a bird to human approach by increasing garden songbird diversity because the pleasure that a person receives from watching an individual bird at a feeder is dependent not only on its species but also on the diversity of birds at the feeder.Support was provided by the Natural Environment Research Council grant NE/J015237/1 [http://www.nerc.ac.uk]
Human-nature interactions and the consequences and drivers of provisioning wildlife.
This is the final version of the article. Available from Royal Society via the DOI in this record.Many human populations are undergoing an extinction of experience, with a progressive decline in interactions with nature. This is a consequence both of a loss of opportunity for, and orientation towards, such experiences. The trend is of concern in part because interactions with nature can be good for human health and wellbeing. One potential means of redressing these losses is through the intentional provision of resources to increase wildlife populations in close proximity to people, thereby increasing the potential for positive human-nature experiences, and thence the array of benefits that can result. In this paper, we review the evidence that these resource subsidies have such a cascade of effects. In some Westernized countries, the scale of provision is extraordinarily high, and doubtless leads to both positive and negative impacts for wildlife. In turn, these impacts often lead to more frequent, reliable and closer human-nature interactions, with a greater variety of species. The consequences for human wellbeing remain poorly understood, although benefits documented in the context of human-nature interactions more broadly seem likely to apply. There are also some important feedback loops that need to be better characterized if resource provisioning is to contribute effectively towards averting the extinction of experience.This article is part of the theme issue 'Anthropogenic resource subsidies and host-parasite dynamics in wildlife'.This work was funded by the Fragments, Functions, Flows and Urban Ecosystem Services project, NERC grant NE/J015237/1, with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme.

Contributors to construction debris from electrical and mechanical work in Hong Kong infrastructure projects
The crucial problem of construction debris is of increasing concern in Hong Kong. In the construction industry, the electrical and mechanical (E&M) installations in the infrastructure, for example, buildings, tunnels, or dams, are some of the major and usually complex components. Difficulty in coordinating the various trades affects productivity in general, and has a major impact on the quantity of construction debris. By identifying the sources of waste at each stage of E&M engineering work, some of the construction debris can be eliminated at the source during production. This paper investigates the critical production shortcomings in the E&M sector in Hong Kong. The study is based on a survey that includes a preliminary questionnaire survey, brainstorming exercises with a focus group, structured interviews with experienced frontline supervisors, and a second focus group exercise to test findings and proposed measures. The principal findings are that "poor coordination" and "design changes and/or errors" are major contributors to variations or change orders and rework, which in turn result in a high volume of construction debris. The results also indicate that construction debris can be minimized in the E&M sector of the construction industry, if the material wastes from incidental work are reduced and also controlled better in a new work process flow pattern through recommended construction project management improvements for reducing critical production shortcomings. © 2009 ASCE.postprin
Key role in ecosystem functioning of scavengers reliant on a single common species.
This is the final version of the article. Available from Nature Publishing Group via the DOI in this record.The importance of species richness in maintaining ecosystem function in the field remains unclear. Recent studies however have suggested that in some systems functionality is maintained by a few abundant species. Here we determine this relationship by quantifying the species responsible for a key ecosystem role, carcass removal by scavengers. We find that, unlike those within largely unaltered environments, the scavenger community within our highly altered system is dominated by a single species, the Carrion crow, despite the presence of a number of other scavenging species. Furthermore, we find no relationship between abundance of crows and carcass removal. However, the overall activity of crows predicts carcass biomass removal rate in an asymptotic manner, suggesting that a relatively low level of abundance and scavenging activity is required to maintain this component of ecosystem function.We thank Deborah & Marin Barlow, Pamela & John Parker & Kim & Justin Dodge, Celia & Paul Tuckfield, Robbie McDonald & Caroline Keenan, Pencoose and Trerose farms for access to their land.

Movement of feeder-using songbirds: the influence of urban features
Private gardens provide vital opportunities for people to interact with nature. The most
popular form of interaction is through garden bird feeding. Understanding how landscape
features and seasons determine patterns of movement of feeder-using songbirds is key to
maximising the well-being benefits they provide. To determine these patterns we established
three networks of automated data loggers along a gradient of greenspace fragmentation. Over
a 12-month period we tracked 452 tagged blue tits Cyantistes caeruleus and great tits Parus
major moving between feeder pairs 9,848 times, to address two questions: (i) Do urban
features within different forms, and season, influence structural (presence-absence of
connections between feeders by birds) and functional (frequency of these connections)
connectivity? (ii) Are there general patterns of structural and functional connectivity across
forms? Vegetation cover increased connectivity in all three networks, whereas the presence
of road gaps negatively affected functional but not structural connectivity. Across networks
structural connectivity was lowest in the summer when birds maintain breeding territories,
however patterns of functional connectivity appeared to vary with habitat fragmentation.
Using empirical data this study shows how key urban features and season influence
movement of feeder-using songbirds, and we provide evidence that this is related to
greenspace fragmentation.This work was

The rarity of direct experiences of nature in an urban population
This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.As people live more urbanised lifestyles there is potential to lose daily contact with nature,
diminishing access to the wide range of associated health benefits of interacting with nature.
Experiences of nature vary widely across populations, but this variation is poorly understood.
We surveyed 1,023 residents of an urban population in the UK to measure four distinctly
different nature interactions: indirect (viewing nature through a window at work and at home),
incidental (spending time outside at work), intentional (time spent in private gardens) and
intentional (time spent in public parks). Scaled-up to the whole study population, accumulation
curves of the total number of hours per week that people were exposed to each type of nature
interaction showed that 75% of nature interactions were experienced by half the population.
Moreover, 75% of the interactions of a type where people were actually present in nature were
experienced by just 32% of the population. The average hours each individual experienced
nature per week varied across interactions: indirect (46.0 ± 27.3 SD), incidental (6.4 ± 12.7 SD),
intentional-gardens (2.5 ± 2.9 SD) and intentional-parks (2.3 ± 2.7 SD). Experiencing nature
regularly appears to be the exception rather than the norm, with a person’s connection to nature
being positively associated with incidental and intentional experiences. This novel study
provides baseline information regarding how an urban population experiences different types of
nature. Deconstructing nature experience will pave the way for developing recommendations for
targeted health outcomes.DTCC, HLH & KJG were funded by NERC grant NE/J015237/1. D.F.S. is supported

Increase in methicillin-resistant Staphylococcus aureus acquisition rate and change in pathogen pattern associated with an outbreak of severe acute respiratory syndrome
Background. An outbreak of severe acute respiratory syndrome (SARS) occurred in our 22-bed intensive care unit (ICU; Prince of Wales Hospital, Hong Kong, HKSAR, China) from 12 March to 31 May 2003, when only patients with SARS were admitted. This period was characterized by the upgrading of infection control precautions, which included the wearing of gloves and gowns all the time, an extensive use of steroids, and a change in antibiotic prescribing practices. The pattern of endemic pathogenic organisms, the rates of acquisition of methicillin-resistant Staphylococcus aureus (MRSA), and the rates of ventilator-associated pneumonia (VAP) were compared with those of the pre-SARS and post-SARS periods. Methods. Data on pathogenic isolates were obtained from the microbiology department (Prince of Wales Hospital). Data on MRSA acquisition and VAP rates were collected prospectively. MRSA screening was performed for all ICU patients. A case of MRSA carriage was defined as an instance in which MRSA was recovered from any site in a patient, and cases were classified as imported or ICU-acquired if the first MRSA isolate was recovered within 72 h of ICU admission or after 72 h in the ICU, respectively. Results. During the SARS period in the ICU, there was an increase in the rate of isolation of MRSA and Stenotrophomonas and Candida species but a disappearance of Pseudomonas and Klebsiella species. The MRSA acquisition rate was also increased: it was 3.53% (3.53 cases per 100 admissions) during the pre-SARS period, 25.30% during the SARS period, and 2.21% during the post-SARS period (P < .001). The VAP rate was high, at 36.5 episodes per 1000 ventilator-days, and 47% of episodes were caused by MRSA. Conclusions. A SARS outbreak in the ICU led to changes in the pathogen pattern and the MRSA acquisition rate. The data suggest that MRSA cross-transmission may be increased if gloves and gowns are worn all the time.published_or_final_versio
Doses of neighborhood nature: the benefits for mental health of living with nature
This is the author accepted manuscript. The final version is available from OUP via the DOI in this record.Experiences of nature provide many mental health benefits, particularly for people
living in urban areas. The natural characteristics of city residents’ neighborhoods are
likely to be critical determinants of the daily nature dose that they receive, however
which characteristics are important remains unclear. One possibility is that the
greatest benefits are provided by characteristics that are most visible during the day
and so most likely to be experienced by people. We demonstrate that of five
neighborhood nature characteristics tested, vegetation cover and afternoon bird
abundances were positively associated with a lower prevalence of depression, anxiety
and stress. Further, dose-response modelling shows a threshold response where the
population prevalence of mental health issues is significantly lower beyond minimum
limits of neighborhood vegetation cover (depression >20% cover, anxiety >30%
cover, stress >20% cover). Our findings demonstrate quantifiable associations of
mental health with the characteristics of nearby nature that people actually experience

The Primitivist Critique of Modernity: Carl Einstein and Walter Benjamin
Compares art historian Carl Einstein's (1885-1940) critique of modernity with that of Walter Benjamin (1892-1940) to explore the modern belief in human achievement, & a primitive awe of mythic fate, as two basic perspectives that defined the 20th-century development of German culture. Both men were interested in the relationship between art & religious forms, but Einstein's writings are relatively unknown, while Benjamin's work has enjoyed a recent revival. Benjamin's concept of modernity is rooted in a progressivist consciousness that accepts evolution from a traditional to a modern world, while Einstein's primitivist rejection of an evolutionary understanding of differences between tradition & modernity led him to see them as "opposite poles of a constant conflict within human society." Benjamin claims collective experience can no longer be transmitted by storytelling & turns to modern methods to relieve the resulting alienation. Einstein's position is conversely based on the assumption that the position of the modern to the outside world is no different than that of the primitive. These distinctions are demonstrated in the two men's readings of fascist cult rituals. J. Lindrot
Urban bird feeding: connecting people with nature
At a time of unprecedented biodiversity loss, researchers are increasingly recognizing the broad range of benefits provided to humankind by nature. However, as people live more urbanized lifestyles there is a progressive disengagement with the natural world that diminishes these benefits and discourages positive environmental behaviour. The provision of food for garden birds is an increasing global phenomenon, and provides a readily accessible way for people to counter this trend. Yet despite its popularity, quite why people feed birds remains poorly understood. We explore three loosely defined motivations behind bird feeding: that it provides psychological benefits, is due to a concern about bird welfare, and/or is due to a more general orientation towards nature. We quantitatively surveyed households from urban towns in southern England, to explore attitudes and actions towards garden bird feeding. Each household scored three Likert statements relating to each of the three motivations. We found that people who fed birds regularly felt more relaxed and connected to nature when they watched garden birds, and perceived that bird feeding is beneficial for bird welfare while investing time in minimising associated risks. Finally, feeding birds may be an expression of a wider orientation towards nature. Overall, we found that the feelings of being relaxed and connected to nature were the strongest drivers. As urban expansion continues both to threaten species conservation and to change peoples’ relationship with the natural world, feeding birds may provide an important tool for engaging people with nature to the benefit of both people and conservation.This work was funded by the Fragments, Functions, Flows and Urban Ecosystem Services project, Natural Environment Research Council grant NE/J015237/1
