Technology level evaluation methodology based on the technology growth curve

Technology has been the driving force of development for knowledge-based economies. As competition in technology innovation among nations becomes more intense, there is a growing need for improved judgment, evaluation and prediction of scientific technology capacity in order to enhance national competitiveness. Until now, a country's technology level has been evaluated on a relative basis by comparing it with that of the country with the world's best technology. However, this kind of static methodology makes the interpretation of results unclear and makes time series analysis difficult. One of the most important limitations of this methodology is that it cannot be used to establish a strategy to improve the technology level. This paper examines the methodological problems of technology level evaluation and develops a dynamic methodology by applying the technology growth curve model. We also analyze the real technology level by using a new model application and review the relevance of this method. Finally, we discuss how to use the results in order to create a dynamic technology strategy.     

Evaluating impacts of institutional reforms on port efficiency changes: Ownership,corporate structure,and total factor productivity changes of world container ports

This paper evaluates how port institutional reforms influenced efficiency gains between 1991 and 2004. We constructed a panel data for port ownership, corporate structure, and port inputs and outputs for 98 major world ports, and we implemented the Malmquist Productivity Index (MPI) model. The MPI provides efficiency measures for input combinations that allow for obtaining the outputs in the presence of institutional reforms, ownership changes, main agent problems, technological progress, efficient scale growth, and many other reasons for efficiency and the lack of it. The results illustrate that ownership restructuring contributed to total factor productivity gains. The restructuring induced optimized operation of container terminals, especially for large ports, as it allowed specialized private entities to concentrate on terminal operation and cargo handling services.     

Developing global champions: Why national oil companies expand abroad

National oil companies (NOCs) have invested hundreds of billions of dollars in foreign oil and gas assets. Why have some governments increased their NOC outward investments, while others have not? I argue that domestic structures can influence a government's calculus that potential benefits, such as added revenues and fuel supply, outweigh potential costs, such as information asymmetries and inefficiencies associated with NOCs. Nationally, partisan competition limits democratic tolerance for failures by NOCs. Bureaucratically, overlapping authority in energy policy undermines coherent NOC governance. Based on investments by NOCs hailing from 79 countries, 2000–2013, I find robust evidence for the national hypothesis.     

Determinants of initial goodwill overstatement in affiliated and non-affiliated mergers

This study examines the determinants of goodwill overstatement at the time of mergers in a Korean setting. In the Korean M&A market, there are two types of mergers: mergers between independent companies (non-affiliated mergers) and mergers between companies under common control (affiliated mergers). This study extends the literature by examining the factors likely to cause goodwill overstatement in both types of mergers. The results reveal that in affiliated mergers, goodwill at the time of a merger tends to be overstated when controlling owners have higher equity ownership in the target than in the acquirer. By contrast, information uncertainty in the target value causes initial goodwill overstatement in non-affiliated mergers. We also find that monitoring of independent institutional investors with concentrated holdings against overpaying for the target is more pronounced when controlling owners in affiliated mergers have incentives to overpay for the target. In affiliated mergers, acquirers tend to write off goodwill more frequently when controlling owners have higher equity ownership in the target than in the acquirer. In non-affiliated mergers, information uncertainty in the target value is significantly associated with subsequent goodwill write-offs. These results suggest that the type of merger has important consequences for initial goodwill recognition and subsequent impairment.     

Comparison of Cramer–Rao lower bounds of variances for at least equal protection of respondents

In this paper, a new randomized response model is proposed, which is shown to have a Cramer–Rao lower bound of variance that is lower than the Cramer–Rao lower bound of variance suggested by Singh and Sedory at equal protection or greater protection of respondents. A new measure of protection of respondents in the setup of the efficient use of two decks of cards, because of Odumade and Singh, is also suggested. The developed Cramer–Rao lower bounds of variances are compared under different situations through exact numerical illustrations. Survey data to estimate the proportion of students who have sometimes driven a vehicle after drinking alcohol and feeling over the legal limit are collected by using the proposed randomization device and then analyzed. The proposed randomized response technique is also compared with a black box technique within the same survey. A method to determine minimum sample size in randomized response sampling based on a small pilot survey is also given.     

Family-based treatment for obesity in tweens: a three-year longitudinal follow-up study

Children's increasing obesity worldwide is creating negative health and socioeconomic drawbacks. To find the determinants of obesity, this research looked at the influence of (1) media usage; (2) advertising messages/brand recognition; and (3) communication or lack of communication between parents and their children on obesity and food-related Purchase Influence Attempts (PIAs) of tweens. A 3-year longitudinal follow-up study was conducted with 68 families whose children were either obese or at risk of becoming obese. The subjects were divided into the following four groups: (1) media amount was controlled; (2) brand recognition was controlled; (3) communication channel of family members was controlled; and (4) all three conditions were controlled. Our results showed significant weight-loss and reduction in PIAs in all groups except in group 2 (brand recognition controlled). This work shows the importance of changing habits using behavioural treatment and the importance of communication among family members on obesity prevention.     

A study on the Effects of Compliments on the Ex-post Responses of Hotel Employees

This study aims to suggest positive organizational management strategies to hotels by empirically analyzing the effects of compliments on emotional satisfaction of hotel employees and thereby their ex-post responses. Verbal compliments had an effect of 0.343 (p?p?相似文献   

Advertising strategy for outbound travel services

When purchasing a travel service, consumers perform multiple information searches. Depending on the accessed information and the type of media for travel service advertisements, consumers make different evaluations on the travel service. Given this context, we propose a consumer persuasion model that reveals the most effective persuasion process for consumers to make purchasing decisions on travel services. For this study, we conducted a comparative analysis to discern effectiveness and limitations between newspapers and TV infomercials; the two major media for travel service advertisements. Based on the results from the analysis, we drew some meaningful managerial implications for travel service advertising strategy.     

Managing and modeling the price reduction effect in mobile telecommunications traffic

As needs for telecommunications services diversify, an increasingly wide range of services is becoming available in the market. Service price reduction is one strategy used by service providers to retain existing subscribers. A price reduction for one service, however, can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, an individual-level usage model for telecommunications services is developed and the effects on usage of a price reduction are analyzed. The model is applied to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, a 0-1 integer programming model is proposed for choosing which market segment should be targeted with a price reduction to minimize revenue loss. These models can be applied to market segmentation and price reduction strategy.     

Palliative care: a paradigm of care responsive to the demands for health care reform in America

Palliative care is poised to become a universally available approach to health care which addresses both the needs of patients and families experiencing serious, progressive, and life-threatening illness, and also the costs of delivering such needed services. Palliative care and hospice are part of a continuum of care with palliative care provided at any time during the illness trajectory, while hospice care is offered at the end of life. Within the context of health care reform, we believe palliative care addresses critical economic imperatives while enhancing quality of life even as death approaches. As leaders in health care, advance practice nurses, specifically, and the nursing community in general are best positioned with the knowledge, expertise, and commitment to advance the specialty of palliative care and lead the way in the reform of America's health care system.
