No full textPreferences of older people for environmental attributes of local parks: The use of choice-based conjoint analysis
No full textPurpose - This study aims to examine the environmental attributes relevant to older people's preferences for neighbourhood open spaces. It also aims to explore the association between the relative importance of different environmental attributes and personal and social characteristics in a sample of older people covering a range of geographic locations in the UK. Design/methodology/approach - Choice-based conjoint analysis (CBC) was used to obtain responses from a sample of 237 older people (60 years +) living in the UK. A total of 13 environmental attributes were identified from earlier qualitative and quantitative studies. Participants were asked to choose a preferred park from a pair of hypothetical neighbourhood parks differing on four of the attributes presented in a questionnaire. The questionnaire included 14 such tasks. Findings - The results suggest that older people preferred a neighbourhood park which is without nuisance, has cafes and toilets, many trees and plants, light traffic en route, wildlife to watch, and is well maintained. Analyses also reveal that whether or not people live alone, and their functional capabilities in getting around, make a difference in the way they place importance on attributes. Practical implications - The findings can assist those involved in designing and managing outdoor environments to identify salient environmental attributes and prioritise interventions aimed at improving access to, and use of, outdoor spaces for older adults. The approach aids understanding of what is likely to maximise preference and use of open spaces in different segments of the older population. Originality/value - Conjoint analysis procedures are some of the best tools available for determining importance or relative value of attributes of complex environments from the user point of view. The CBC analysis has been employed for the first time in this study to explore the relative importance of such attributes of open spaces for older adults. © Emerald Group Publishing Limited.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Preferences of Older People for Environmental Attributes of Local Open Space

Design/methodology/approach
Choice‐based conjoint analysis (CBC) was used to obtain responses from a sample of 237 older people (60 years +) living in the UK. A total of 13 environmental attributes were identified from earlier qualitative and quantitative studies. Participants were asked to choose a preferred park from a pair of hypothetical neighbourhood parks differing on four of the attributes presented in a questionnaire.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Do changes to the local street environment alter behaviour and quality of life of older adults? The ‘DIY Streets’ intervention
Full text link<p>Background: The burden of ill-health due to inactivity has recently been highlighted. Better studies on environments that support physical activity are called for, including longitudinal studies of environmental interventions. A programme of residential street improvements in the UK (Sustrans ‘DIY Streets’) allowed a rare opportunity for a prospective, longitudinal study of the effect of such changes on older adults’ activities, health and quality of life.</p>
<p>Methods: Pre–post, cross-sectional surveys were carried out in locations across England, Wales and Scotland; participants were aged 65+ living in intervention or comparison streets. A questionnaire covered health and quality of life, frequency of outdoor trips, time outdoors in different activities and a 38-item scale on neighbourhood open space. A cohort study explored changes in self-report activity and well-being postintervention. Activity levels were also measured by accelerometer and accompanying diary records.</p>
<p>Results: The cross-sectional surveys showed outdoor activity predicted by having a clean, nuisance-free local park, attractive, barrier-free routes to it and other natural environments nearby. Being able to park one's car outside the house also predicted time outdoors. The environmental changes had an impact on perceptions of street walkability and safety at night, but not on overall activity levels, health or quality of life. Participants’ moderate-to-vigorous activity levels rarely met UK health recommendations.</p>
<p>Conclusions: Our study contributes to methodology in a longitudinal, pre–post design and points to factors in the built environment that support active ageing. We include an example of knowledge exchange guidance on age-friendly built environments for policy-makers and planners.</p>
Outdoor environmental supportiveness and older people’s quality of life: a personal projects approach
Full text linkWe present an approach to exploring the role of environmental supportiveness in contributing to older people’s quality of life (QoL), based on Little’s ecological model (2010) in which individual and situational factors influence the personal projects of salience to individuals.
Personal Projects are self-generated and purpose-oriented activities or goals in which an individual is engaged (Little, 1983). The efficacy with which the pursuit of these activities is achieved depends on the nature of the project and the degree to which it is supported by external factors such as the environment. We explore the relationship between the outdoor environment and QoL, drawing on the concept of ‘environmental support’ as presented by Sugiyama and Ward Thompson (2007a).
There is a positive relationship between the number of outdoor personal projects older people participated in and measures indicative of their QoL. The relationship between perceived environmental support and QoL measures was significant in projects involving nature but not for other project types
