This paper aims to understand what goes on in the black box of successful, joined-up ICT-enabled service transformation, where complex interactions and integration must occur among the horizontal processes internal to a joined-up service delivery network, the vertical top-down processes of the organizations involved, and the change processes caused by using ICTs. A new conceptual framework is developed and applied to an illustrative case study of successful, joined-up service transformation in New Zealand.  相似文献

Recent evidence from the USA suggests that people engaged in occupations involving providing care for others, such as childcare and teaching, suffer a wage penalty. After taking into account job and individual characteristics such as level of education and work experience, people in these occupations in the American study earned about 6 per cent less than their peers in other types of occupation. However, we do not yet know if people working in similar occupations in other countries also suffer the same degree of disadvantage. The issue is important because, despite the perception that people in caring jobs place a relatively low weight on the level of remuneration when making career decisions, a number of studies have shown clear evidence of an association between pay and the propensity to give up working in a caring occupation. There are implications too for social inequality as many caring jobs are done by women and associated wage penalties could contribute to the persistent gender gap in pay. This study compares and contrasts the predictions of neoclassical economics, cultural feminist theory and social closure theory. Data are taken from 17 waves of the British Household Panel Survey and include a total of 23,773 individuals, giving 110,677 person‐year observations. These data are analysed using multi‐level linear regression. The results show clear evidence of a statistically significant wage penalty associated with working in some caring occupations. Those occupations requiring lower levels of educational qualification, such as nursing assistants and auxiliaries, are particularly hard‐hit by the wage penalty. On the other hand, some occupations, such as medicine and teaching, have fared better than comparable non‐caring occupations over the same period. We discuss the implications of these results for the gender gap in pay, poverty, social inequality and the future supply of caring workers.  相似文献

E-commerce is a strategy for rapid growth, especially by small and medium sized businesses (SMEs). However, the adoption rate of e-commerce by SMEs in Latin America is still undersized. The authors compare the theory of planned behavior (TPB) and the theory of reasoned action (TRA) using structural equation modeling to determine which is better at predicting e-commerce adoption intentions among 210 SME managers/owners in Chile. Contrary to previous research with American respondents, the study does not find significant differences between the two theories. Thus, academics should select the more parsimonious model (TRA) to study e-commerce adoption issues in developing countries.  相似文献

Democracy, foreign direct investment and natural resources   总被引:1,自引:0,他引:1  
Empirical studies that examine the impact of democracy on foreign direct investment (FDI) assume that the relationship between democracy and FDI is the same for resource exporting and non-resource exporting countries. This paper examines whether natural resources in host countries alter this relationship. We estimate a linear dynamic panel-data model using data from 112 developing countries over the period 1982-2007. We find that democracy promotes FDI if and only if the value of the share of minerals and oil in total exports is less than some critical value. We identify 90 countries where an expansion of democracy may enhance FDI and 22 countries where an increase in democratization may reduce FDI. We also find that the effect of democracy on FDI depends on the size and not the type of natural resources.  相似文献

The aim of this paper is to take a holistic perspective to explore levels of cycling and opportunities and barriers to increase children’s safer cycling in disadvantaged areas in England. The study was one part of a larger study which explored the factors underlying the high level of road traffic casualties especially among children in the most disadvantaged areas of England and to explore how this impacts on mobility and quality of life. The methods involved a cross sectional survey comprising school based questionnaire surveys with children aged 9-14 and focus groups with parents who had children within this age range. The surveys were conducted in 2007 and the focus groups during 2008. 4286 children completed the survey and eight focus groups were held. Bike ownership (77%) was high, use in previous week moderate (39%) but only 2% cycled to school. Ownership was significantly lower in minority ethnic groups. Despite young children’s strong preference to travel by cycle (30%) than walk or go by car, most parents felt it was too hazardous. It is unlikely that these findings would be any different from the rest of England, however the combination of environmental and social factors may elevate the risks for young cyclists in these areas. This paper concludes that a number of barriers exist to increasing levels of cycling among children living in disadvantaged areas particularly amongst ethnic groups. These barriers could be addressed by environmental modifications to reduce speeds and by reducing the levels of antisocial driving and riding in residential areas and around destinations where children travel, by providing cycle training to improve children’s skills and parent’s confidence, and by providing secure storage facilities for bikes. Until these barriers are addressed it is unlikely that cycling will increase despite the strong preferences children have to travel by bike. Such preferences to cycle provide an opportunity for local authorities to act on.  相似文献

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.  相似文献
