围绕ICU的几个问题的思考 总被引:2,自引:0,他引:2
张忠鲁 《医学与哲学(人文社会医学版)》2006,27(2):16-19
ICU是现代医学中的新兴事物,发挥着重要作用,但是围绕ICU方方面面问题,无论是业界还是公众还有许多争论及认识上的误区,有待研究探讨,比如ICU是否是一个真正意义上的独立学科?ICU的业态形式?ICU一定是高投入高装备吗?ICU注定是高消费?ICU有人文伦理缺失的特权吗?本文试图对这些问题给予一点作者的观察和己见。 相似文献

Many organizations face competing agendas by which they are expected to simultaneously grow sales output while controlling associated costs. At the interface of this organizational pressure and the sales force’s implementation of such initiatives is the sales manager. However, questions with significant implications remain regarding how a sales manager’s requisite engagement with cost control affects sales performance. To address this issue, the authors conceptualize and operationalize the notion of sales manager cost control engagement. Results from a survey of 178 business-to-business sales managers show the antecedent and consequence effects of sales manager cost control engagement. A variety of organizational factors are shown to effectively direct the sales manager’s attention to cost control, which in turn has a positive impact on cost-related sales performance. These findings add to an emergent body of research aimed at understanding key skills required of sales managers for driving sales performance as well as provide a novel perspective for sales managers to consider when balancing pressures between cost inputs and sales outputs. Several theoretical and managerial implications are offered, as are future research directions. 相似文献

Do egalitarians always express greater compassion toward the disadvantaged than toward the advantaged? A closer look at existing scholarship on the topic suggests that they likely do. Here, we investigated whether such tendency is also apparent within interdependent, high power distance cultures where the high‐status privilege prevails. Given the emphasis on harmony in social relations in interdependent cultures, we reasoned that egalitarians might experience a dissonance between their private equity values and a societal norm prescribing high‐status privilege, which we refer to as the value‐norm conflict. We therefore proposed and found evidence in Malaysia (N = 273) that egalitarians succumbed to the normative high‐status privilege in their culture: They displayed greater compassion towards higher than lower status victims, but only when the political cost of doing so was low. Interestingly, anti‐egalitarians displayed equitable levels of compassion for high‐ and low‐status victims, but only when the political cost for taking such action also was low. Hence, we show that even egalitarians can, at times, favor the privileged and that anti‐egalitarians can act equitably, so long as the political cost of doing so is trivial for them. 相似文献

We examine the question of whether the human comprehension device exhibits word-order preferences during on-line sentence comprehension. The focus is on the positioning of finite verbs and auxiliaries relative to subjects and objects in German. Results from three experiments (using self-paced reading and event-related brain potentials) show that native speakers of German prefer to process finite verbs in second position (i.e., immediately after the subject and before the object). We will account for this order preference in terms of the relative processing costs associated with SVfO and SOVf. Our finding that word-order preferences play an important role in the on-line comprehension of German sentences is compatible with results from previous studies on English and other languages. 相似文献

Positive reinforcement contingencies can sometimes be used to decrease problem behavior maintained by negative reinforcement (e.g., escape). In the current study, we evaluated the extent to which response cost (i.e., contingent removal of a preferred stimulus) would compete with the negative reinforcer maintaining destructive behavior. The response cost contingency reduced destructive behavior by 87% from baseline levels even though the negative reinforcement contingency (i.e., escape) remained in place. 相似文献

The present study aimed to adapt the Driving Cost and Benefit Scale (DCBS, Taubman-Ben- Ari, 2008) to Chinese drivers and examine its relationships with driving style and traffic violations. Nine hundred drivers aged 18 to 60 years were asked to complete the DCBS and the Multidimensional Driving Style Inventory. The results of exploratory factor analysis (n = 429) and confirmatory factor analysis (n = 429) yielded a 36-item scale with satisfactory reliability. The Chinese version of the DCBS contains seven factors, including three driving cost factors (damage to self-esteem, life endangerment and distress) and four driving benefit factors (impression management, sense of control, thrill and pleasure). Significant associations between the DCBS-C factors and driving styles and traffic violations show that the discriminant validity of the scale is acceptable. Moreover, the driving cost factor of damage to self-esteem and the driving benefit factor of thrill both contributed to drivers’ traffic violations and crashes. The findings show that the reliability and validity of the Chinese version of the DCBS are acceptable, and it can be used as a tool to measure driving motivation in China. 相似文献

Introduction
Competition between French local communities to build infrastructures to attract enterprises and residents could sometimes result in irrational public spending.Objectives
Show the influence of psychological factors and the phenomenon of escalating commitment in particular on this type of economic decision.Method
We conducted a survey comprising four scenarios which were sent to 285 local elected representatives and we study the impact of the factors “Amount of sunk costs” and “Level of project completion” on two dependent variables, “the desire to complete the project” and “the judgment regarding the quality of the investment”. The scenarios presented a project which involve servicing a site and the construction of a road infrastructure in order to attract an enterprise.Results
In conformity with the works of Boehne and Paese, whatever the dependent variable, the level of project completion significantly explains the escalation of commitment. The hypothesis of “sunk costs” is confirmed when the escalation of commitment is measured by the dependent variable “desire to complete the project”.Conclusion
We have highlighted the effect of sunk costs and level of project completion on the decisions of local elected representatives, enriching the understanding of economic decision factors. 相似文献118.
The sunk cost effect across species: A review of persistence in a course of action due to prior investment 下载免费PDF全文
Paula Magalhães K. Geoffrey White 《Journal of the experimental analysis of behavior》2016,105(3):339-361
The sunk cost effect is the bias or tendency to persist in a course of action due to prior investments of effort, money or time. At the time of the only review on the sunk cost effect across species (Arkes & Ayton, 1999), research with nonhuman animals had been ecological in its nature, and the findings about the effect of past investments on current choice were inconclusive. However, in the last decade a new line of experimental laboratory‐based research has emerged with the promise of revolutionizing the way we approach the study of the sunk cost effect in nonhumans. In the present review we challenge Arkes and Ayton's conclusion that the sunk cost effect is exclusive to humans, and describe evidence for the sunk cost effect in nonhuman animals. By doing so, we also challenge the current explanations for the sunk cost effect in humans, as they are not applicable to nonhumans. We argue that a unified theory is called for, because different independent variables, in particular, investment amount, have the same influence on the sunk cost effect across species. Finally, we suggest possible psychological mechanisms shared across different species, contrast and depreciation, that could explain the sunk cost effect. 相似文献
