Even before business has really come to grips with the intricacies of incorporating emarketing and e-commerce into their organisational strategies, they are now being encouraged to make significant investments in developing capabilities for mobile phone marketing. Fuelled once again by huge profit predictions reminiscent of the mid-1990s when speaking of e-commerce (Anckar and D’Incau 2002) marketers are tapping into this mobility. So, instead of having to drive consumers to web sites through the ‘sit and search’ context, marketers are now exploring ways to develop strategies to deliver relevant and timely information in a ‘roam and receive’ context directly to their potential customers anywhere, anytime, any place (Mort and Drennan 2002).

There has been a long dependency on credit by Indonesian farmers as a result of the lack of capital to apply proper farming practices. This paper describes the farming activities applied by agricultural credit users in Central Lombok, Indonesia. A survey was conducted during July 2001- March 2002 of 65 farmers making use of government or private credit in three villages within the Regency. Data from the farmers were collected using face-to-face, semi-structured interviews. Survey results indicated that on average, farmers had some 20 years experience of farming, were aged 40 years, but lacked of formal education. Their main asset was cropping land with average landholding of 0.69 ha. As a consequence of their capital constraints, farmers were commonly making use of credit to finance their farming activities, including both production of rice as the main crop and secondary crops. Farmers generally applied less than recommended amount of inputs in their farming practices, since the amount of credit they obtained was limited. As a result, their farms become less productive and their repayment capability of loans diminished. Of 65 farmers interviewed, 54 could earn extra income by engaging in a variety of non-farm activities, which contributed on average some 36% to family incomes of over Rp 5 million (A$ 1 thousand). The average credit repayment rate made by agricultural producers was 60%. The repayment made did not always reflect farm production capacity, being sometimes supported by other borrowings. The greater role of credit is not in increasing agricultural production or improving farmers’ income, but in helping them to sustain farm production and their living. Farmers need a bigger amount of credit to make an impact on their livelihood. This should be accompanied by extension services for farmers to enable better use of credit and to change their attitude towards it. As well, farmers require to be equipped with technical and market skills to run a business. Interdisciplinarity, holistic analysis, and an expansion of traditional ‘agricultural’ interests to embrace the span of interests included in rural livelihood, are each critical features of revision of the existing system.

Objectives Ecstasy is a recreational drug whose active ingredient, 3,4-methylenedioxymethamphetamine (MDMA), acts predominantly on the serotonergic system. Although MDMA is known to be neurotoxic in animals, the long-term effects of recreational Ecstasy use in humans remain controversial but one commonly reported consequence is mild cognitive impairment particularly affecting verbal episodic memory. Although event-related potentials (ERPs) have made significant contributions to our understanding of human memory processes, until now they have not been applied to study the long-term effects of Ecstasy. The aim of this study was to examine the effects of past Ecstasy use on recognition memory for both verbal and non-verbal stimuli using ERPs. Methods We compared the ERPs of 15 Ecstasy/polydrug users with those of 14 cannabis users and 13 non-illicit drug users as controls. Results Despite equivalent memory performance, Ecstasy/polydrug users showed an attenuated late positivity over left parietal scalp sites, a component associated with the specific memory process of recollection. Conlusions This effect was only found in the word recognition task which is consistent with evidence that left hemisphere cognitive functions are disproportionately affected by Ecstasy, probably because the serotonergic system is laterally asymmetrical. Experimentally, decreasing central serotonergic activity through acute tryptophan depletion also selectively impairs recollection, and this too suggests the importance of the serotonergic system. Overall, our results suggest that Ecstasy users, who also use a wide range of other drugs, show a durable abnormality in a specific ERP component thought to be associated with recollection.

The aim of this paper is to provide managers and Human Resource executives with the basis for making drug testing policy in their organisations by presenting a critical review of existing literature on Workplace Drug Testing (WDT) and related areas which have been structured into the key areas.The key finding is whilst WDT is becoming more and more widely used, the rationale for this in terms of organizational effectiveness and safety is far from clear. Also there are significant ethical issues associated with WDT which are not always fully considered by organisations. Similarly, a cost/benefit analysis for particular organisations may well show little reason to embark on a testing policy. As a result of our review, we recommend that practitioners take a critical view of proposals introducing WDT since in many cases there is little upside to such a policy and a largely under-researched downside. There are also wider implications for society as a whole since the issue of drug taking as a whole is clearly a matter of great importance to practically every country in the world. The workplace is not at all immune from the impact of drug taking and perhaps a knee-jerk response by managers is to attempt to exclude anyone with any sort of drug habit through the use of WDT. This type of review with a specific HR focus has not been carried out before despite several calls for a more rational approach to the area.

Following grounded-theory methodology, this thesis provides an analysis of the volunteering experiences of 47 wheelchair-users. It challenges the traditional image of volunteering which tends to conceptualise non-disabled people as the instigators of voluntary action (the helpers) and disabled people as the recipients of volunteerism (the helped). It also begins to fill a notable gap in academic knowledge about the volunteering experiences of disabled people. The literature review showed that contemporary conceptualisations of disability were unsuitable for this thesis. Thus, an organising framework is proposed which acknowledges that disabled peoples’ experiences may be influenced by medically and socially constructed factors – or by a combination of both acting simultaneously (medical-social factors). Having conceptualised disability for the purposes of the study, the thesis then provides an account of the research methodology used. This is followed by a presentation of research findings. An analysis of the volunteers’ demographic, epidemiological and background characteristics is provided and their perceptions of the benefits of, and barriers to, volunteering highlighted. This is followed by an analysis of their volunteering experiences. Theory is developed in order to explain the volunteers’ experiences from the approach outlined within the organising framework. The final part of the thesis adopts a reflexive approach to contextualise the research processes from the writer’s own perspective as a disabled person conducting research into the lived experiences of other disabled people. The thesis concludes by highlighting the implications of the study for future social research.

The proliferation of visual display terminals (VDTs) in offices is an international phenomenon. Numerous studies have investigated the health implications which can be categorised into visual problems, symptoms of musculo-skelctal discomfort, or psychosocial effects. The psychosocial effects are broader and there is mixed evidence in this area. The inconsistent results from the studies of VDT work so far undertaken may reflect several methodological shortcomings. In an attempt to overcome these deficiencies and to broaden the model of inter-relationships a model was developed to investigate their interactions and Ihc outputs of job satisfaction, stress and ill health. The study was a two-stage, long-term investigation with measures taken before the VDTs were introduced and the same measures taken 12 months after the 'go-live' date. The research was conducted in four offices of the Department of Social Security. The data were analysed for each individual site and in addition the total data were used in a path analysis model. Significant positive relationships were found at the pre-implementation stage between the musculo-skeletal discomfort, psychosomatic ailments, visual complaints and stress. Job satisfaction was negatively related to visual complaints and musculo-skeletal discomfort. Direct paths were found for age and job level with variety found in the job and age with job satisfaction and a negative relationship with the office environment. The only job characteristic which had a direct path to stress was 'dealing with others'. Similar inter-relationships were found in the post-implementation data. However, in addition attributes of the computer system, such as screen brightness and glare, were related positively with stress and negatively with job satisfaction. The comparison of the data at the two stages found that there had been no significant changes in the users' perceptions of their job characteristics and job satisfaction but there was a small and significant reduction in the stress measure.

This thesis investigates corporate financial disclosure practices on Web sites and their impact. This is done, first by examining the views of various Saudi user groups (institutional investors, financial analysts and private investors) on disclosure of financial reporting on the Internet and assessing differences, if any, in perceptions of the groups. Over 303 individuals from three groups responded to a questionnaire. Views were elicited regarding: users attitude to the Internet infrastructure in Saudi Arabia, users information sources about companies in Saudi Arabia, respondents perception about the advantages and disadvantages in Internet financial reporting (IFR), respondents attitude to the quality of IFR provided by Saudi public companies and the impact of IFR on users information needs. Overall, it was found professional groups (Institutional investors, financial analysts) hold similar views in relation to many issues, while the opinions of private investors differ considerably. Second, the thesis examines the use of the Internet for the disclosure of financial and investor-related information by Saudi public companies (113 companies) and look to identify reasons for the differences in the online disclosure practices of companies by testing the association between eight firm-specific factors and the level of online disclosure. The financial disclosure index (167 items) is used to measure public company disclosure in Saudi Arabia. The descriptive part of the study reveals that 95 (84%) of the Saudi public companies in the sample had a website and 51 (45%) had a financial information section of some description. Furthermore, none of the sample companies provided 100% of the 167 index items applicable to the company. Results of multivariate analysis show that firm size and stock market listing are significant explanatory variables for the amount of information disclosed on corporate Web sites. The thesis finds a significant and negative relationship between the proportion of institutional ownership of a companys shares and the level of IFR.
