This paper presents a conceptual framework that hypothesizes the nature of the relationships between a firm’s use of Internet-based information technology (IT), supply chain planning capability, and operational performance. Using data from 266 manufacturing sites and structural equation modeling, we show that the impact of IT on operational performance is contingent upon the intent of its use. Specifically, our results suggest that IT’s use in exploiting existing opportunities has both a direct effect and an indirect effect, mediated through supply chain planning capabilities, on operational performance. In contrast, when IT is used to explore new opportunities, it has neither a direct nor an indirect effect on operational performance. Implications of these research findings are reported.  相似文献

It is widely recognized that new product development (NPD) is a highly interdependent process, yet efforts to empirically model the interdependence and examine its effect on firm performance are scarce. Our study addresses this research gap. We model firms’ abilities to collectively collaborate with suppliers, customers, and internal employee teams in NPD as collaborative competence and examine its impact on project and market performance. Using responses collected from 189 NPD managers, we find empirical evidence for collaborative competence and its differential impact on project and market performance. Specifically, we find that collaborative competence has a direct impact on project performance, but its impact on market performance is indirect, mediated through project performance. The results have significant managerial implications; achieving superior market performance from inter- and intra-organizational involvement is contingent on achieving superior project performance, and companies that fail to achieve desired project performance outcomes will also fail in achieving market performance goals.  相似文献

The curriculum for undergraduate engineering courses in Malaysia is becoming increasingly structured, following the global trend for quality assurance in engineering education, through accreditation schemes. Generally, the accreditation criteria call for the graduates from engineering programs to demonstrate a range of skills, from technical problem solving to soft skills and an aptitude for lifelong learning. In order to comply with these criteria, accreditation schemes are adopted as a quality assurance measure. This paper shall introduce the characteristics of the engineering accreditation scheme in Malaysia. The impact of the accreditation scheme on the quality of these engineering programs shall be evaluated. Data collection is in the form of benchmarking and questionnaires. The evaluation criteria shall be in terms of benefits to the institution, academic faculty, students, and the challenges encountered. A discussion on the evaluation shall include the supposed dichotomies which arise from this accreditation process, namely the compromise between research versus teaching; and the value of engineering knowledge whether as an academic pursuit or catering to industry’s needs. Ultimately, this paper shall address a fundamental question related to undergraduate teaching in engineering: whether accreditation is a necessary prerequisite in maintaining high standards in engineering programs in Malaysia.  相似文献

As it is currently taught, instruction in engineering ethics centers on cognitive learning even to the extent of suppressing the involvement of emotions in ethical decision making. The common belief is that emotional involvement will increase the likelihood of poor judgment. Recent neuroscience research with positron emission tomography and functional magnetic resonance imaging indicates that emotions actually play a significant role in ethical decision making. It then follows that emotions should be part of ethics education: That is, discussions of ethics should not be limited to cognitive thought. Instruction to improve emotional maturity must be accompanied by teaching of cognitive subject matter if long‐term learning is to occur. Emotions influence the solution of ethical problems as they affect the accuracy of the problem assessment and the accuracy, intensity, and duration of an emotive response. Specific emotions that relate to ethical decisions are listed. A theory of emotive learning is presented, and its application to the teaching of engineering ethics is discussed. Strategies for emotive learning are also presented.  相似文献

There is significant evidence of the practice of creative accounting by large listed corporations. However, little is known about the process by which such schemes are devised and succeed in escaping legal and regulatory sanction. This study examines this process of creative compliance in the case of complex convertible securities issued by U.K. listed companies between 1987 and 1990. There was an active dialectic of creativity in the design of these instruments — a shift from avoidance to rules to avoidance again. The evidence shows how a small group of professionals in finance, law and accountancy cooperated in the development of these instruments. They helped the issuers to manage their financial reporting process in a way in which compliance was assured. Where regulatees are able to command such creative compliance skills and resources, regulators may find themselves facing an uphill struggle.  相似文献

The objectives of this paper are to incorporate a measure of risk aversion in the translog frontier cost function to estimate cost inefficiency. Risk-averse behaviour of farmers is hypothesised to reduce efficiency by leading to a situation in which the marginal value product of an input is less than price. In developing agriculture, farmers are aware of their subsistence needs and seek to minimize the probability of their incomes falling below a disaster level of income. Using such a safety first principle, a measure of risk-taking is developed and explained by socio-economic characteristics. This measure is used in the translog cost function as a fixed input and, using the frontier approach (with half normal distribution of inefficiency disturbance), a measure of cost inefficiency is obtained. This is related to socio-economic characteristics such as education, assets and holding size. A survey data of 436 farmers for the North-West Frontier Province of Pakistan is used to reach policy conclusions for reducing cost inefficiency.  相似文献

An error-correction model is used to estimate the fraction of consumers who are liquidity-constrained in 10 Asian developing countries. Our estimates of the fraction of consumers who are liquidity-constrained range between 0.25 and 0.98. We further investigate whether financial liberalization has resulted in the reduction of liquidity constraints in these countries. However, the results find support for this only in the cases of South Korea, Sri Lanka and Taiwan.  相似文献

Aim: To estimate the healthcare utilization and costs in elderly lung cancer patients with and without pre-existing chronic obstructive pulmonary disease (COPD).

Methods: Using Surveillance, Epidemiology and End Results (SEER)-Medicare data, this study identified patients with lung cancer between 2006–2010, at least 66 years of age, and continuously enrolled in Medicare Parts A and B in the 12 months prior to cancer diagnosis. The diagnosis of pre-existing COPD in lung cancer patients was identified using ICD-9 codes. Healthcare utilization and costs were categorized as inpatient hospitalizations, skilled nursing facility (SNF) use, physician office visits, ER visits, and outpatient encounters for every stage of lung cancer. The adjusted analysis was performed using a generalized linear model for healthcare costs and a negative binomial model for healthcare utilization.

Results: Inpatient admissions in the COPD group increased for each stage of non-small cell lung cancer (NSCLC) compared to the non-COPD group per 100 person-months (Stage I: 14.67 vs 9.49 stays, p?<?.0001; Stage II: 14.13 vs 10.78 stays, p?<?.0001; Stage III: 28.31 vs 18.91 stays, p?<?.0001; Stage IV: 49.5 vs 31.24 stays, p?<?.0001). A similar trend was observed for outpatient visits, with an increase in utilization among the COPD group (Stage I: 1136.04 vs 796 visits, p?<?.0001; Stage II: 1325.12 vs 983.26 visits, p?<?.0001; Stage III: 2025.47 vs 1656.64 visits, p?<?.0001; Stage IV: 2825.73 vs 2422.26 visits, p?<?.0001). Total direct costs per person-month in patients with pre-existing COPD were significantly higher than the non-COPD group across all services ($54,799.16 vs $41,862.91). Outpatient visits represented the largest cost category across all services in both groups, with higher costs among the COPD group ($41,203 vs $31,140.08).

Conclusion: Healthcare utilization and costs among lung cancer patients with pre-existing COPD was ~2–3-times higher than the non-COPD group.  相似文献
