More and more organisations formulate a code of conduct in order to stimulate responsible behaviour among their members. Much time and energy is usually spent fixing the content of the code but many organisations get stuck in the challenge of implementing and maintaining the code. The code then turns into nothing else than the notorious "paper in the drawer", without achieving its aims. The challenge of implementation is to utilize the dynamics which have emerged from the formulation of the code. This will support a continuous process of reflection on the central values and standards contained in the code. This paper presents an assessment method, based on the EFQM model, which intends to support this implementation process.  相似文献

We explore the effects of uncertainty on a firm that can respond by modifying its investment or production schedule (or both simultaneously) to variations in output price. Investment may increase capacity and/or reduce costs. We consider a firm with finite resources.Our model uses option theory instead of the more traditional net present value framework. One of the early papers using this approach is Brennan and Schwartz (1985) in which an investment project to extract a finite natural resource is valued. In that paper, the value of the firm is a function of two state variables, the finite resource to be extracted (output to be produced in the future) and the commodity spot price. In order to maximize firm value, the manager can respond by modifying one control variable, the production level. In our model we handle instead three state variables (spot price, resources, accumulated investment) and two control variables (production rate and investment rate), and solve numerically.We obtain both the value and the optimal policy of a firm that has investment projects that increase capacity and/or reduce costs and illustrate optimal policies as resources and available investments decrease over the life of the firm. Firms may start by only investing, then invest and produce, to end only producing.We thank Scott Wo, the referee and the editor for their comments and suggestions.

This study aimed to describe the distribution of injury mechanisms and to assess the impact of those mechanisms on the morbidity and mortality of trauma. All patients admitted to Puerto Rico Trauma Hospital (2002–2011) for road-traffic collisions (RTCs, 5,371), gunshot wounds (GSWs, 2,946), falls (2,319), pedestrian accidents (1,652), and stab wounds (SWs, 1,073) were selected. Gunshot victims were 1.19 (95%CI: 1.07–1.33) times as likely as road-traffic victims to have an ISS ≥25. Pedestrians were 1.76 (95%CI: 1.49–2.09) times more likely to have a GCS ≤8 than road-traffic victims were. The risk of dying was 2.64 (95%CI: 2.20–3.16) times higher for gunshot victims and 1.51 (95%CI: 1.23–1.86) times higher for pedestrians compared to patients who had had RTCs. Gunshot victims and pedestrians had the worst clinical outcomes. Accordingly, these patients should receive the most aggressive clinical management. Furthermore, it is imperative to develop public health campaigns on trauma prevention.  相似文献

Luxury marketing research has moved from functional product attributes to a ‘democratized’ view in emerging economies. This seems to be based on the development of interactive and digital communications. Luxury research studies have historically focused on the brand's and marketer's perspectives. Thus, little attention has been given to the consumer's view of what we consider to be the individual drivers, i.e., the ‘inner and outer self’ and how that impacts luxury consumption. This paper presents a framework of luxury and self, using concepts such as interdependent or outer, independent or inner, and a new concept of ‘digital self’. These appear as three levels of luxury consumption, i.e., conspicuous, individual, and interactive. The interdependent self is influenced by the external motives and leads to conspicuous luxury behavior. Individual self is affected by internal motives and thus influences individual luxury consumption. Digital self affects the networks of motive and relationships and thereby impacts interactive luxury consumption and behavior.  相似文献

The literature on stochastic input–output (I–O) analysis has paid considerable attention to the bias in the Leontief inverse. This paper extends previous studies by assuming supply and use tables (SUTs rather than I–O tables or input coefficients matrices) to be stochastic. This is a natural starting point because SUTs have become the basic data sources for I–O applications. In a Monte Carlo simulation experiment, a given SUT is randomized in two different ways and the effects are determined for eight different multiplier matrices. The analysis is carried out for Spain, Italy, the Netherlands, Germany and Finland, using their SUTs for 2006. The findings indicate that, in general, biases are statistically significant but negligibly small. This corroborates earlier findings obtained for stochastic I–O tables.  相似文献

The Färe‐Primont index is used to evaluate total factor productivity (TFP) change and its components for a sample of French suckler cow farms in grassland areas in 1985–2014. The results reveal an increase in TFP of 6.6 per cent over the whole observation period, with technological progress being the major source of productivity growth. Meanwhile, efficiency decreased. Farms experienced great technological progress from 1991 to 2000. From a methodological point of view, the comparison with results obtained with Malmquist indexes shows similar trends but different magnitudes, with the Malmquist index overestimating the TFP and technological changes compared to the Färe‐Primont index. In addition, the use of a sequential approach that restricts technological change to being positive or null allows for the precise calculation of technology changes, disregarding the effects of external conditions that are captured in efficiency changes. Finally, the estimation of full dimensional efficient facets (FDEFs) that guarantees the positivity of all shadow prices used to assess the mix efficiency component of TFP change is promising.  相似文献

Projects seeking to define, measure, and evaluate audit quality are on the agendas of auditing standards setters as well as audit firms. The Public Company Accounting Oversight Board (PCAOB) currently provides information regarding audit quality through the release of inspection reports, and the Board intends to establish and report audit quality indicators. To provide additional perspective on audit quality, we obtain auditors' and investors' views, definitions, and indicators of audit quality. We find that investors' definitions of audit quality focus more on inputs to the audit process than do auditors', and that investors view the number of PCAOB deficiencies as an indicator of overall firm quality. We find a consensus that auditor characteristics may be the most important determinants of audit quality, and that restatements may be the most readily available signal of low audit quality. We relate responses to a general audit quality framework, provide support for archival audit research, and identify additional disclosures that participants suggest could signal audit quality. Taken together, we provide evidence regarding the construct of audit quality in the post‐SOX environment, evaluate many of the audit quality indicators proposed by the PCAOB, and suggest avenues for future research.  相似文献

Many digital service providers have adopted gamification to promote customer engagement. Critical questions, however, remain about the most effective way to enhance customer engagement and increase sales by applying gamification. With a research design that combines qualitative and quantitative methods, including the use of objective sales data from a large field study and replication of the findings across different contexts, this study explores how gamification fosters customer engagement. Both field study results and a simulation study reveal gamification principles (i.e., social interaction, sense of control, goals, progress tracking, rewards, and prompts) that promote hope and consequently increase customer engagement and digital sales. Furthermore, we find that hope is more strongly associated with customer engagement than the psychological condition of compulsion, which even exerts a negative impact. This research thus explores how gamification creates value for customers and provides actionable insights for managers to foster hope through gamification as opposed to get customers hooked.  相似文献

In this opinion piece, the author speculates on the future of advertising. Arguing that the challenge of predicting the future lies mainly in the lack of an acceptable definition of the field, the author solves that problem by developing a set of postulates to create boundaries for the theory and practice of the discipline. The postulates of the present discipline are used as the base from which the future might evolve. Three scenarios are proposed for the future of advertising: (1) creeping incrementalism, (2) reversal of buyer/seller roles, and (3) reinvention of the field. The author suggests that those scenarios will develop and play out based on the developmental speed and acceptance of the various technologies identified.  相似文献
