Editorial

Improving the urban environment for these vulnerable and excluded groups will be a key challenge for the planners of the future. So how can any interested readers reflect this in their own work? We argue here that the design of urban land use and public transport access for such heterogeneous populations demands collaborative multi-professional working between urban designers, urban planners, users, researchers, campaign groups, policy-makers and managers.Taking up this challenge, this themed issue on ‘Disabilities and vulnerable road users in the urban environment’ draws on insights from European research leaders and campaigners

Conceptual and lexical functioning in blind, severely visually impaired and sighted infants

This thesis examines the role of vision in language development by focusing on: first, the understanding blind infants have of objects, actions/events and the way they start to talk about these aspects of their environment; and, second, the ways visual information contributes to conceptual and lexical development in sighted infants. Until recently, research has predominantly focused on infants' understanding of objects and their understanding of actions/events has been neglected. Since individuals who are blind predominantly have access to temporal, rather than spatial infomation and so are better able to process information about actions and events rather than objects, this bias seems to have led to the conclusion that an absence of visual information results in a cognitive deficit. Six blind/severely visually impaired infants and their sighted controls were studied for around a year using a range of quasi-experimental, parental report and observational techniques. The studies found little difference between the blind and sighted infants in the age of onset or rate at which first words are produced. However, blind infants were found to be delayed in the age at which they were able to comprehend and produce labels for objects and they produced few words for concrete, discrete objects. The finding that the blind infants were able to categorize objects/actions as well as generalise and extend their words calls into question Dunlea's (1989) claim that an absence of visual information leads to a cognitive deficit. It is argued that blind infants can make their way into language using a route which is merely one end of a spectrum of routes used by sighted infants. Implications are discussed for theories of lexical development (multiroute model, developmental lexical principles framework and the social-pragmatic framework) as well as for possible strategies facilitate conceptual and lexical development in blind/SVI and sighted infants

A Critical Analysis of IQ Studies of Adopted Children

Abstract The pattern of parent-child correlations in adoption studies has long been interpreted to suggest substantial additive genetic variance underlying variance in IQ. The studies have frequently been criticized on methodological grounds, but those criticisms have not refl ected recent perspectives in genetics and developmental theory. Here we apply those perspectives to recent IQ adoption studies and show how they further question two sets of problems: fi rst, the assumption of additive gene and environmental effects; second, the assumption that the adoption situation approximates a randomizedeff ects design. We show how a number of possible factors having systematic eff ects in breach of those assumptions can produce the received pattern of correlations without appealing to unusual amounts of additive gene variance

Developing a smartphone app to enhance Oxfam's supply chain visibility

This paper reports on the development of a smartphone app designed to give drivers and managers in a charity organisation greater visibility of transport, donation bank and shop stock in time and space. Trials of the app with samples of drivers and shop managers across three counties in the UK showed that users’ understanding of vehicle activity and how time was utilised in the business was enhanced. The app also informed their decision making, aided some collaboration and helped in their understanding of donation bank and shop performance, with one region altering their collection schedules. The quality of 3G signal was an issue in certain areas which impeded performance and the rules by which the messaging platform should be used in such a tool need careful consideratio

Tourism and the smartphone app: capabilities, emerging practice and scope in the travel domain.

Based on its advanced computing capabilities and ubiquity, the smartphone has rapidly been adopted as a tourism travel tool.With a growing number of users and a wide varietyof applications emerging, the smartphone is fundamentally altering our current use and understanding of the transport network and tourism travel. Based on a review of smartphone apps, this article evaluates the current functionalities used in the domestic tourism travel domain and highlights where the next major developments lie. Then, at a more conceptual level, the article analyses how the smartphone mediates tourism travel and the role it might play in more collaborative and dynamic travel decisions to facilitate sustainable travel. Some emerging research challenges are discussed

The missing dimension : The relevance of people's conception of time

While a timely conceptual innovation for the digital age, the “map” proposed by Bentley et al. would benefit from strengthening through the inclusion of a non–clock-time perspective. In this way, there could be new hypotheses developed which could be applied and tested relevant to more diverse societies, cultures, and individuals

Maternally perceived barriers to and facilitators of establishing and maintaining tooth-brushing routines with infants and preschoolers

Establishing effective toothbrushing routines using fluoridated toothpaste in infancy has been suggested as important to dental health throughout childhood and into adulthood. However, previous studies have revealed a number of potential barriers to, and facilitators of caregivers ability to establish early dyadic toothbrushing routines with pre-schoolers. However, as yet no qualitative research has been conducted to ascertain potential barriers and facilitators of the earliest dyadic toothbrushing in infancy, and nor has any previous research specifically focused on how novice mothers of first-born infants and preschoolers manage this task. This study therefore outlines findings from a qualitative interview study with first-time mothers of children aged 24–30 months (n = 16) exploring perceived barriers to and facilitators of early dyadic toothbrushing routines with infants and preschoolers. A number of key themes were identified from interview transcripts and an ‘ecological’ approach conceptualised maternally perceived barriers to and facilitators of dyadic toothbrushing. Proximal influences were found to be located within the caregiver-child relationship (‘micro-system’), including parental cognitions (e.g., PSE), parental behaviours (e.g., parenting practices) and infant and preschooler temperament and behaviours (e.g., tantrums). Distal factors were also identified as relevant to the establishment and maintenance of these routines, such as social support (‘exosystem’) and family history of tooth-brushing (‘chronosystem’)

Fundamental challenges in designing a collaborative travel app

The growing capabilities of smartphones have opened up new opportunities for travel coordination and transport is a fertile area for app development. One stream of development is apps that enable collaborative travel, either in the form of lift sharing or collaborative shopping, but despite growing interest from governmental agencies, there is little evidence of the efficacy of such apps. Based on trials of purpose built travel collaboration apps, deployed in tourism, urban and rural residential communities, and logistics, this paper analyses the fundamental challenges facing users adopting such travel apps. The findings suggest that transport practitioners, policy makers and app developers need to better understand the challenges associated with attracting users, the use of incentives and the types of communities most appropriate to implement collaborative travel concepts using such approaches. Also, how the users’ sense of time pressure and the issues around reciprocal exchange can impact on their long-term success and wider adoption

Tourism communities and social ties: the role of online and offline tourist social networks in building social capital and sustainable practice.

Mobile connectivity enables the adoption of new ways to connect with social networks which are changing how we might, and could, seek support. In the tourism domain we increasingly blend online and offline presence to engage with social networks in the spatial location, at a distance and across time. This paper explores the forms of community that exist in physical tourism contexts, contexts not previously analysed through a community lens, and explores how mobile technology is creating connections within and beyond existing social networks. It examines how sustainable tourism can be enhanced by mobile connectivity through new space-time practices and using ephemeral interpersonal relationships to harness niche groups to create bottom-up social systems interested in sharing experiences, ideas and resources. Special attention is given to the concept of gelling socialities which proposes a less ridged network structure, and to the need to understand the increasingly liquid social dynamics of mobile social interactions. The paper adds to the theories surrounding community, social ties and tourism’s value to society. It draws on data from in-depth interviews undertaken while designing and testing a collaborative travel app. It contributes to growing research into the new technologies increasingly available for sustainable tourism marketing and implementation
