This study introduces an optimal capacity and operation design of a robot logistics system that can reduce human workload in the hotel industry. In hotels, there are several duties that can be replaced by robots such as accompanying guests to the certain areas, delivering specific items to the guest rooms, and transporting some items that guests want to be removed from the guest rooms. To apply the robot logistics system in the hotel industry, the capacity and operation design should be prepared adequately. For that, a mathematical model-based optimization technique is used to decide the number of robots with the concept of minimizing total investment cost and to derive the optimal job assigning with the purpose of maximizing total covered jobs. In addition, a numerical example is performed to validate the proposed mathematical model and the sensitivity tests are examined to reflect the random features. 相似文献

In a two-country Schumpeterian growth model, we study the incentives for basic research investments by governments in a globalized world. A country׳s basic research investments increase with the country׳s level of human capital and decline with its own market size. This may explain why some smaller countries invest so much in basic research. Compared with the optimal investments achievable when countries coordinate their basic research policies, a single country may over-invest in basic research. However, the total amount of decentralized basic research investments is always below the socially optimal investment level, which justifies policy coordination in this area. 相似文献

This study investigates debt market effects of research and development (R&D) costs capitalization, using a global sample of public bonds and private syndicated loans issued by public non‐financial firms. Firstly, we show that firms capitalize larger amounts of R&D in a year when they exhibit a propensity for issuing bonds, rather than borrowing funds privately from the syndicated loan market, in the subsequent year. Secondly, we provide evidence that capitalized R&D investments reduce the cost of debt. We infer that debt market participants are able to identify firms’ motives for R&D capitalization, as we find a reduction in the cost of debt only for those firms that do not show indications of employing R&D capitalization for earnings management reasons. Indeed, only for this sub‐sample of firms, the amount of capitalized R&D contributes positively to future earnings. We confirm that R&D capitalization is positively associated with audit fees and thus can be deemed to be a signaling device. Lastly, we find that it is the amount of R&D a firm is expected to capitalize and not the discretionary counterparts, which facilitates a firm's access to public debt markets, reduces bond and syndicated loan prices, and contributes to future benefits. 相似文献

This paper reviews the pitching template proposed by Faff ( 2015 ). The article highlights the usefulness of this template for researchers. It is observed that there is scope for adapting this tool, with a template suitable for qualitative researchers being proposed. In the light of the various methodological differences through different research paradigms, it is envisaged that this adaptation will assist in bridging the schism between qualitative and quantitative research. It is also hoped that the proposed enhanced template will encourage qualitative researchers to submit to mainstream accounting journals and quantitative researchers to comprehend the value of qualitative research. 相似文献

We respond to calls for advances in the contextualization of international business (IB) research by introducing interactive visualization as a methodology for generating contextual insights during the exploratory phases of IB research projects. We suggest that applying interactive visualization early on improves contextualization by means of simultaneous dynamic representations of various phenomena and their respective properties and relationships, even for phenomena that have been widely researched before, like in the cases of international joint ventures and MNE foreign direct investment. The goal of this introduction is to make interactive visualization more accessible to IB scholars. 相似文献

In light of the dramatically aging workforces in many industrialized countries, age diversity management will become a major challenge in human resource management. To successfully handle an age-diverse workforce, it is crucial to understand how employees of different ages can be motivated. This paper analyzes age's moderating role in the relationship between situational job characteristics and job satisfaction. To control for the potential influence of the cultural and institutional context, we use data from the USA, Japan and Germany. Findings show that older employees' job satisfaction is driven by different factors than younger employees: older employees put more emphasis on good relationships with colleagues, while income, advancement opportunities, job security and having an interesting job are less important. However, these effects are mostly nation-dependent, which underlines the importance of conducting cross-cultural or cross-national aging research. 相似文献

A lack of empirical studies on Supply Chain Risk Management (SCRM) is observed, especially in the industries of large projects. Therefore, this paper conducts a risk analysis on the Brazilian Shipbuilding Industry by generating an initial risk profile. A panel was conducted with executives from major shipyards, and the primary risks were identified, assessed, and evaluated. Findings corroborate the academic literature, reinforcing that companies recognise the importance of SCRM, but the concept is incipient and far from being successfully implemented in real life. Despite the fact that the shipyards identified important risks, the focus was on internal factors. Because the industry was exposed to risks from the external environment, no risk mitigation actions existed, resulting in the bankruptcy of many shipbuilders. This research is an initial step toward investigating SCRM techniques, offering academics a novel empirical approach that can serve as a systematic risk management tool for supply chain planning. 相似文献
