Urban agriculture,gender and empowerment: An alternative view

Studies of urban agriculture (UA) in South Africa, and more broadly in southern Africa, have drawn on quantitative research methodologies to explain the involvement in UA of people from low-income households. Such studies tend to explain UA with reference to the direct economic and monetary gains that are made through agricultural activity. In Cape Town, the contribution of UA to income generation and expenditure substitution is limited. However, UA is important to women of low-income households in ways less directly related to monetary gain. Women use UA in processes of empowerment, to establish social networks, to symbolise a sense of security and to encourage community development. Policy-makers should extend their perception of UA's benefits beyond narrow economistic notions to include these positive social effects.     

Increasing correlations or just fat tails?

Increasing correlation during turbulent market conditions implies a reduction in portfolio diversification benefits. We investigate the robustness of recent empirical results that indicate a breakdown in the correlation structure by deriving theoretical truncated and exceedance correlations using alternative distributional assumptions. Analytical results show that the increase in conditional correlation could be a result of assuming conditional normality for the return distribution. When assuming a popular alternative distribution – the bivariate Student-t_r – we find significantly less support for an increase in conditional correlation and conclude that this is due to the presence of fat tails when assuming normality in the return distribution.     

Opportunities for Air Pollutant and Greenhouse Gas Emission Reduction through Local Transport Planning

This paper has three main objectives: firstly, to provide quantitative information on the potential greenhouse gas and air pollutant emissions reductions resulting from a number of future road transport scenarios; secondly, to illustrate the emission reduction measures available to local transport planners; and thirdly, to highlight the potential for these measures to be integrated into strategies that deliver other transport priorities. The results are drawn from a case study of Norfolk in the UK. We conclude that while technology can play a large part in reducing emissions of air pollutants, demand management is crucial to the delivery of long term greenhouse gas emission reduction and ultimately of air pollutant emissions too.     

Negotiating Technology Implementation: An Empirical Investigation of a Website Introduction

Negotiated implementation is suggested as a cogent approach to meeting user and implementer needs, and thus, to increasing technology implementation. Negotiated implementation is expected to have its effect through three wellknown dimensions: ease of use, usefulness, and commitment. The efficacy of negotiated implementation is tested in the context of a universitybased field study of World Wide Web site use. Empirical support is found for the negotiated implementation approach. Implications and future research related to both theory and application are provided.     

Exploring supermarket loyalty card analysis to identify who buys fairtrade

The aim of this paper is to show how supermarket loyalty card data from a panel of over 1.7 million shoppers can be analysed to provide insights to profile the fairtrade shopper in order to enhance making targeted marketing decisions. The paper demonstrates the huge marketing potential that loyalty-card-based shopper segmentation can bring to objectively describe who buys fairtrade products, compared to profiling shoppers through a claimed/reported behaviour data-set. A paired-samples t-test is used to test the degree of appeal of fairtrade tea, coffee, chocolate, drinking chocolates, banana and sugar categories in Tesco to life-stage and lifestyle shopper segments in terms of their retail sales values over 104 weeks. The results show that analysing loyalty cards based on actual behaviour provides a more detailed picture of how specific fairtrade food product categories appeal to the various life-stage and lifestyle shopper segments.     

Testing servers' roles as experts and managers of tipping behaviour

This article studies the ability of servers to predict their own tips. A distinction is made between the two roles of servers with regard to tipping behaviour: the role of expert and the role of manager. As experts, servers understand the relations between several predictors and tip size, and are able to predict the tip they are about to receive. As managers, servers designate certain tip amounts, and then manage the service encounter so that their predictions are realised. This study maps the necessary conditions for an expert position and outlines the process for managing a service encounter. Empirical testing suggests that servers have an impressive predictive ability. The findings also offer some support to the view of the role of the server as manager.     

Social marketing theory development goals: an agenda to drive change

ABSTRACT

Environmental, health, and social change is complex and frequently is framed as a problem(s) to be solved. This framing focuses effort on delivery of solutions designed to change systemic environmental, health, and social problems. Theory, an organising framework for effort, remains under-utilised in behavioural and social sciences. An individual psychological lens dominates and emphasis is placed on explaining and predicting individual behaviour and not behavioural change. It is time to break free and deliver frameworks that extend focus beyond individuals to all citizens, and apply new evaluation approaches that assess individual and structural changes. Ten Social Marketing Theory Development Goals (goals) categorised in three groups: (i) research design; (ii) building social marketing theory; and (iii) methodological innovation are outlined to assist social marketers to develop new ways of thinking that will deliver the theory and evidence base needed to outline what practitioners and policy makers should do to effect change.     

A dual-process model of how incorporating audio-visual sensory cues in video advertising promotes active attention

Capturing consumers’ attention to video advertising is a key marketing challenge. Using real video advertising viewed by a sample of consumers matching the US population on age and gender, the authors examined attention to audio-visual and visual sensory cues identifying the brand using a biometric measure, phasic heart rate. The findings show differences in attention type depending on which senses are stimulated by the sensory cue. This research uncovers a mechanism (internal processing) for how consumers process multisensory cues (audio-visual) in video advertising and confirms visual sensory cues can elicit automatic attention through the orienting response. In addition to the dual-coding explanation for the superiority of audio-visual sensory cues, the present research suggests a second reason: that audio-visual sensory cues can elicit additional internal processing of the brand name, resulting in active attention and better storage of the brand in memory. This has implications for the limited capacity model of motivated mediated message processing, as well as for marketers relating to the type of content recommended to follow an audio-visual or visual sensory cue in video advertising.     

Modelling drought and recovery in the southern Murray‐Darling basin*

The prolonged drought from 2006–07 to 2008–09 in south‐eastern Australia presented severe difficulties for dry‐land and irrigation farmers in the southern Murray‐Darling basin. A dynamic multi‐regional computable general equilibrium model (TERM‐H2O) is used to estimate the economy‐wide small region impacts during and after drought. Drought reduces real GDP in some small regions by up to 20 per cent. Irrigation water trading and farm factor movements alleviate losses. The drought results in an estimated 6000 jobs being lost across the southern basin. Depressed farm investment during drought results in farm capital not returning to baseline levels after drought. Consequently, job numbers in 2017–18 remain 1500 below forecast in the southern basin.
