Dually sustainable urban mobility option: Shared-taxi operations with electric vehicles

Electric vehicles (EVs) are energy efficient and often presented as a zero-emission transport mode to achieve long-term decarbonization visions in the transport sector. The implementation of a sustainable transportation environment through EV utilization, however, requires the addressing of certain cost and environmental concerns such as limited driving range and battery-charging issues before its full potential can be realized. Nevertheless, a specific type of use of EVs, namely in taxi services, may elicit positive public opinion, as it promises a commitment toward sustainability in urban life. In light of this, this study proposes an integrated approach that combines EV operation with a conceptual design for shared-ride taxi services. As some productivity loss may be naturally expected due to the time spent in charging, it is important to look at whether such performance loss from the passenger and system standpoints can be offset with ingenuity in operational design. In this study, an EV taxi charge-replenishing scheme that can be coupled with a real-time taxi-dispatch algorithm is designed. The proposed EV charging schemes for taxi services are studied via simulations and the effects of the limited driving range and battery-charging details are examined from a system performance viewpoint. The simulation study also reveals illustrative results on the impact of the EV taxi fleet's operation on the charging system. Next, a real-time shared-taxi operation scheme that allows ride sharing with other passengers is proposed to maximize the operational efficiency. The simulation results suggest that the shared-taxi concept can be a viable option to improve on the limitations caused by EV operation. In addition, the importance of projected charging demands and queue delays at different charging locations are also addressed. Some limitations and a future research agenda are also discussed.     

Risk perception by industrial radiographers: Hungary and the UK compared

Perceptions of risks from two groups of industrial radiographers, one from Hungary, (n = 45) and from the United Kingdom, (n = 29) were compared by the psychometric method. The comparison was made because both groups were at risk for high doses of ionizing radiation. We found the groups had similar demographic profiles but poor socio-economic conditions of Hungarians were associated with higher levels of emotional distress. Correlation HU-UK for personal and general risks were at a significant level for topics that included lifestyle and radiation risks. Perceptions of risks from radiation were small except for large personal risk from East European nuclear power plants. Knowledge of radiation risk intranationally was correlated positively with personal risk for UK radiographers and negatively for Hungarians. However, average overall risk perceptions from the same topic list for all radiographers did not differ significantly from a group (n = 1461) of UK citizens, though radiographer's risks from radiation were considerably greater. As a new lifesaving intervention it was proposed that radiation risk reduction could be achieved by genetic testing.     

Making Sense of One Dollar CEO Salaries

We examine the determinants and outcomes of Chief Executive Officers (CEOs) accepting a $1 salary, a compensation practice that occurs relatively frequently in high‐profile firms and is debated by regulators, investors, and the media. Using a hand‐collected sample of 93 CEOs from 91 firms between 1993 and 2011, we examine the triggers preceding the $1 salary decision, the factors associated with the decision, subsequent stock returns, and the outcomes for the CEOs. Our evidence is consistent with two explanations for the phenomenon: (i) it is a gesture of sacrifice by CEOs of firms in crisis, and (ii) it is a signal of better future performance by CEOs of growing firms. Our analyses highlight the two different circumstances and shed light on an interesting debate that has thus far been supported only by anecdotal evidence.     

Does local political support influence financial markets? A study on the impact of job approval ratings of political representatives on local stock returns

Using data on job approval ratings of governors, U.S. senators, and the president, we find that firms located in states with high approval ratings outperform firms located in states with low approval ratings by .64% per month. Furthermore, this relationship is stronger when investors are actively involved in politics, when local politicians are closer to the center of political power, for small firms that have a larger proportion of local investors, and for financially strong areas where investors are ready to execute investments in local stocks. Overall, our study shows that investors’ political sentiment is important in determining stock returns.     

Tariffs and formation of free trade agreements networks

This paper examines the formation of bilateral free trade agreements (FTAs) on the basis of country heterogeneity in the tariff level. We demonstrate that a country's unilateral incentive to form an FTA depends on the relative magnitudes of the (negative) market concession effect and the (positive) market expansion effect, both of which are determined by the tariff levels of the two FTA partner countries. Global welfare is maximised when all country pairs form FTAs. Two countries in equilibrium are more likely to form an FTA when their tariff gap is smaller or when their tariff levels are neither very high nor very low. This finding is robust to several extensions of the model. Our preliminary empirical analysis provides some evidence for the finding.     

South Korea’s outward direct investment and its dyadic determinants: Foreign aid,bilateral treaty and economic diplomacy

This study investigates the factors that affect South Korean outward foreign direct investment (FDI) in developing countries. Most previous studies focus on monadic factors and do not consider how and to what extent bilateral relationships between South Korea and the host countries affect the investment decisions of Korean firms. The current study finds that interstate factors such as South Korea's international investment treaties with and official development assistance to host countries have positive effects on FDI to these countries, while presidential visits have strong and statistically significant effects on FDI only in countries located in non-Asian regions, especially the African continent. The findings suggest that the effects of bilateral relations on South Korea's FDI vary depending on the geographic location of the host country.     

How far can brands go to defend themselves? The extent of negative publicity impact on proactive consumer behaviors and brand equity

Negative publicity, defined as the public disclosure of a problematic incident associated with a brand, is a critical issue for fashion brands, as it vitiates the image of targeted brands and drives consumers’ voice and exit behaviors. Despite the impact of negative publicity, few studies have compared the impact of product‐related versus personnel‐related negative publicity, or explored the extent to which brands’ coping strategies can prevent consumers’ anti‐brand behavioral intentions and recover brand equity. This study used multivariate analyses of variance to analyze responses from 594 American consumers, which revealed that when negative publicity is about a product‐related issue, none of the brand's different recovery efforts are effective in decreasing consumers’ voice and exit intentions and protecting brand equity. However, for a personnel‐related issue, functional and informational recovery strategies were effective in decreasing consumer voice and exit intentions, and affective, functional, and informational recovery strategies positively impacted most domains of brand equity (brand judgement, brand feelings, and brand resonance). The following analysis of variance and post hoc analyses revealed the comparative effectiveness of specific recovery types. Discussions and implications of the findings are provided.     

Cultural value,consumption value,and global brand image: A cross‐national study

In expanding their market to the global level with clear and consistent global brand images across nations, marketers are ever confronting the issue of how to deal with different cultural values. Cultural value is identified as an influential factor on brand image and is widely accepted as one of the crucial concepts in understanding consumer consumption value, which determines choices of consuming everyday products and services. Most firms endeavoring to establish and maintain consistent global brand images, however, adopt a standardized brand image strategy that usually does not consider individual target markets” characteristics, including the concepts of cultural value and consumption value. This study developed a conceptual framework which incorporated cultural value not only as a direct antecedent of brand image, but also as an indirect antecedent of brand image through consumption value, and empirically tested it using the category of apparel. Following this framework, this study hypothesized the differences in brand image, cultural value, and consumption value between the U.S. and South Korea. Data were gathered through surveying university students residing in the San Francisco and Seoul metropolitan areas using a convenience sampling method. A total of 329 completed questionnaires were used in factor analysis, discriminant analysis, and structural equation modeling. The results provide insights into standardized brand image strategies and suggest some implementable tools that might prove effective in both countries. © 2009 Wiley Periodicals, Inc.     

A Prototype of Multicomponent Brand Personality Structure: A Consumption Synmbolism Approach

Brand personality (BP) in the postmodern marketplace encompasses a variety of anthropomorphized attributes associated with a brand, reflecting on a wide spectrum of social, cultural, and psychological associations capturing various aspects in everyday life stories of consumers. Most prior research onBP, however, has employed a psychology‐based approach, and has not yet fully demonstrated the concept's market‐driven scope in the contemporary brand schema. To bridge the gap between the practitioner and scholar, this study employed a consumption symbolism approach to develop a multicomponent structure ofBP. A qualitative study was conducted with 36 brands of six product/service categories (fashion/luxury, beverage, automotive, personal computer, cosmetics, and retailer) within a specific context (South Korea). The results yielded a prototype of multicomponent BP structure consisting of one psychological component (traits) and three sociocultural components (narratives of socioeconomic/life scene/physical variability). The findings of the study broaden the current understanding of BP by suggesting a multidisciplinary perspective embracing its sociocultural aspects, and by empirically demonstrating the prototype reflecting on a wide spectrum of consumer narratives.
