Injury is a leading cause of morbidity and mortality in the United Arab Emirates (UAE). The UAE is a rapidly developing country with fast economic growth, demographical and environmental changes that are associated with new hazards emerging at a similar pace. The UAE as a federal entity has federal and local systems responsible for safety policy, regulations and enforcement. To set priorities for safety promotion and injury prevention, it is necessary to have data on the most frequent external causes of injury and the main individual, equipment and environmental risk factors that contribute to injury. However good quality data for injury prevention are scarce. The aim of this paper is to describe the scale of injury as a public health problem in the UAE, and the development of safety policies, regulations and promotion efforts with special emphasis on traffic, occupational and child safety.  相似文献

Platforms for SaaS-based enterprise applications are prospering and the number of on-demand ERP vendors is increasing. We combine both phenomena for the first time and illustrate how the integration of a sustainability benchmarking service into an on-demand ERP platform provides added value beyond pure cost savings. By applying a qualitative system dynamics approach we identify self-reinforcing mechanisms which allow a faster and more comprehensive market penetration compared to providing these services separately.  相似文献

Recent studies cast doubt on the ability of abstract experiments to predict decision‐making in the field. Thus, scholars have argued for more ‘realism’ by introducing context to field experiments. Yet, such realism may work against the induced values of monetary incentives in economic experiments. It is an open question whether contextual framing works best with or without inducing values, through methods such as the use of monetary incentives. Using a sample of 146 German farmers, we compare experimentally the predictive power of a framed lottery in an agricultural context vs. using an abstract version. For one half of the sample, lotteries are incentivised; for the other half, they are hypothetical. Although risk preferences differ between treatments, all four lottery tasks correlate poorly with farmers’ real‐world use of risk management instruments such as harvest or hail insurance. Subjects who start with an agricultural framing are willing to take significantly greater risks in the lotteries. More generally, our findings cast doubt on the ability of lottery tasks to predict risk‐taking in the field.  相似文献

This account explores certain aspects of the developments in international, interEuropean holiday travel as a part of the phenomena characterised as modernity and Europeanisation. The focus is on the idea of 'travelling parochialism', i.e. whether large proportions of contemporary international holidaymakers and other travellers on their tours within Europe adopt some kind of furtherance of a home-like culture. The main point of departure is the idea of the 'tourist bubble' understood here as a territorial and functional differentiation and as an expectation of holidaymakers going abroad. The concept of 'travel ecumene' is introduced to examine implications for travellers of the development of a western European travel system. Moreover, the study analyses the extent to which the notion of the tourist bubble is still beneficial in comprehending significant aspects of inter-European holiday travel in relation to current discourses of internationalisation, Europeanisation and cosmopolitanism. The paper also discusses advances of cosmopolitan predilections and aspirations and their possible influences on contemporary international European tourism.  相似文献

Purpose: In business markets, working with customers and users has become increasingly important to get knowledge about customer needs and to develop new products. The purpose of this article is twofold: (1) to develop a framework for analyzing customer involvement in product development in a business market context, and (2) to apply this framework to a particular company to describe and analyze how it practices customer involvement.

Methodology/approach: The article takes its main theoretical starting point in the industrial network approach, but also uses other literature from the innovation and product development field. The empirical study applies a qualitative case study approach and focuses on one company in the truck business.

Findings: The suggested framework deals with four key aspects of customer involvement: Why, when, how, and who. The observed pattern of the truck manufacturer shows how dealers, hauliers, and truck drivers are all part of the overall understanding of the customer. These actors are involved for different, typically very clear, purposes at different points in time through surveys, product clinics, and field testing. The pattern, referred to as mixed facilitative, is not one of close collaboration with individual customers, but one of broad involvement of several customers through business intelligence and direct involvement.

Research implications: First, the article provides researchers with a framework and method for studying customer involvement in product development. Second, the case study provides an illustrative example of the customer involvement pattern pursued by a leading company in a major industry. This enhances the understanding of the focal phenomenon, leads to managerial implications, and gives ideas for future research.

Practical implications: There are several managerial implications related to the why, when, how, and who questions. For example, it is pointed out that managers should consider involving customers more extensively than what seems to be common today—for example, by using customers as codevelopers, working with them throughout the entire development process (i.e., not only early and late), and including different types of users (with different requirements and wishes).

Originality/value/contribution of the article: The contribution lies in the development of a framework centered on the four key questions of customer involvement in

product development and using this framework for observing a pattern, and finding explanations and relating this pattern to how other firms are doing.  相似文献

Consumers worldwide are increasingly concerned with sustainable production and consumption. Recently, a comprehensive study ranked 17 countries in regard to their environmentally friendly behaviour among consumers. Brazil was one of the top countries in the list. Yet, several studies highlight significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour: the so‐called ‘Attitude‐Behaviour Gap’. In developing countries, few studies have been conducted on this issue. The objective of this study is therefore to investigate the gap between citizens' sustainability‐related attitudes and food purchasing behaviour using empirical data from Brazil. To this end, Brazilian citizens' attitudes towards pig production systems were mapped through conjoint analysis and their coexistence with relevant pork product‐related purchasing behaviour of consumers was investigated through cluster analysis. The conjoint experiment was carried out with empirical data collected from 475 respondents surveyed in the South and Center‐West regions of Brazil. The results of the conjoint analysis were used for a subsequent cluster analysis in order to identify clusters of Brazilian citizens with diversified attitudes towards pig production systems, using socio‐demographics, attitudes towards sustainability‐related themes that are expected to influence the way they evaluate pig production systems, and consumption frequency of various pork products as clusters' background information. Three clusters were identified as ‘indifferent’, ‘environmental conscious’ and ‘sustainability‐oriented’ citizens. Although attitudes towards environment and nature had indeed an influence on citizens' specific attitudes towards pig farming at the cluster level, the relationship between ‘citizenship’ and consumption behaviour was found to be weak. This finding is similar to previous research conducted with European consumers: what people (in their role of citizens) think about pig production systems does not appear to significantly influence their pork consumption choices. Improvements in the integrated management of this chain would better meet consumers' sustainability‐related expectations towards pig production systems.  相似文献

In this paper determinants of information systems (IS) outsourcing are deduced from transaction cost economic theory, resource-based theory and power theory. They are summarized in a theoretical framework which is tested using a sample of small and medium sized enterprises (SMEs) in Germany. The results show that internal performance and know-how deficits vis-à-vis external service providers are key determinants that explain why different IS functions are outsourced to varying degrees in SMEs. Moreover, the determinants of IS functions were found to partially differ between IS functions. Revised reprint of an article from WIRTSCHAFTSINFORMATIK 43(4)2001:339–350.

We analyze a two-attribute single item procurement auction that uses yardstick competition to settle prices. The auction simplifies the procurement process by reducing the principal’s articulation of preferences to simply choosing the most preferred offer as if it was a market with posted prices. This is done simply by replacing the submitted sealed bids by yardstick bids, computed by a linear weighting of the other participants’ bids. We show that there is only one type of Nash equilibria where some agents may win the auction by submitting a zero price-bid. Using a simulation study we demonstrate that following this type of equilibrium behavior often leads to winner’s curse. The simulations show that in auctions with more than 12 participants the chance of facing winner’s curse is around 95 %. Truthful reporting, on the other hand, does not constitute a Nash equilibrium but it is ex post individually rational. Using a simulation study we demonstrate that truthful bidding may indeed represent some kind of focal point.  相似文献
