ABSTRACT In 2013, China and India officially established an economic corridor (the Bangladesh–China–India–Myanmar Economic Corridor, BCIM-EC) that would cut across Myanmar and Bangladesh. But while the formal process of cooperation among the four countries is in place, many obstacles to its implementation remain at the international, national and local levels. Is meaningful collaboration possible within the BCIM-EC framework? In terms of two dimensions of structural power as conceptualised by Susan Strange, security and trade, China’s structural power in Myanmar is much stronger than India’s. It is therefore likely that this imbalance will prevent the BCIM-EC project, which currently appears to be overshadowed by China’s Belt and Road Initiative, from having a fruitful outcome. 相似文献

The article introduces the theoretical perspective on gradual institutional change to the corporatization literature. This is achieved via a longitudinal case study on the institutionalization of the Danish state guarantee model (SGM) for transport infrastructure based on archival document studies of seven infrastructure projects and 31 interviews with elite actors and experts. The article explores with a detailed analysis how the gradual change mechanisms of layering, conversion and displacement coexist, are interrelated, and are coevolving over a long period. It contributes to the corporatization literature presenting the SGM as an alternative to public and private partnerships and government agencies. 相似文献

Bone marrow (BM) analysis is of forensic interest in postmortem toxicological investigation in case of limited, unavailable or unusable blood samples. However, it remains difficult to determine whether a drug BM concentration is therapeutic or represents overdose, due to the lack of studies on this alternative matrix. Given the variations in BM composition in the body, sample location was suggested to be a relevant factor in assessing BM concentration. The aim of the present study was to compare postmortem caffeine concentrations in various BM sample locations and secondly to consider the correlation between BM and blood concentrations. Six BM samples (right and left side: proximal and medial femur and 5th rib) and a blood sample were collected from 21 forensic autopsies. Gas chromatography coupled to tandem mass spectrometry was performed. Blood caffeine concentrations ranged from 60 to 7591ng/mL. Femoral and rib BM concentrations ranged from 51 to 6171ng/g and 66 to 7280ng/g, respectively. Blood concentrations were always higher than BM concentrations. As a good correlation was demonstrated between blood and rib BM and between blood and the average of the four femoral BM concentrations, blood caffeine concentrations could be correctly extrapolated from BM concentrations. BM caffeine concentration was found to depend on sample location. Rib BM caffeine concentrations appeared to be systematically greater than averaged femur values and concentrations were much more variable between the 4 femur BM samples than between the 2 ribs. From a practical point of view, for caffeine analysis, rib BM appeared more relevant than femoral BM, which requires multisampling to overcome the concentration variability problem. 相似文献

Face recognition systems aim to recognize the identity of a person depicted in a photograph by comparing it against a gallery of prerecorded images. Current systems perform quite well in controlled scenarios, but they allow for none or little interaction in case of mistakes due to the low quality of images or to algorithmic limitations. Following the needs and suggestions of investigators, we present a guided user interface that allows to adjust from a fully automatic to a fully assisted modality of execution, according to the difficulty of the task and to amount of available information (gender, age, etc.): the user can generally rely on automatic execution and intervene only on a limited number of examples when a failure is automatically detected or when the quality of intermediate results is deemed unsatisfactory. The interface runs on top of a preexistent automatic face recognition algorithm in such a way to guarantee full control over the execution flow and to exploit the peculiarities of the underlying image processing techniques. The viability of the proposed solution is tested on a classic face identification task run on a standard publicly available database (the XM2VTS), assessing the improvement to user interaction over the automatic system performance. 相似文献

A major policy concern regarding patenting activity is related to the actual enforceability of the patents granted by Patent Offices. The risk of facing elevated legal costs to defend patent rights can affect ex-ante incentives to invest in R&D. This paper analyses whether the availability of insurance policies that cover legal expenditures for patent litigation could increase the appropriability of the innovation. We model a situation in which an incumbent innovator is endowed with a valid patent and an entrant imitator can either directly enter the market or try to apply for a patent, hoping that an error will be made by the Patent Office. The incumbent can accommodate the entrant, file a suit to a civil court or offer a settlement agreement. We model the presence of heterogeneity in the risk that the patents will face an error by both patent examiners at Patent Offices and judges at civil court. We analyse the changes in expected profits for the innovator when given the possibility of buying an insurance policy which will cover legal costs in the event of trial. We compare the cases in which (i) coverage is voluntary and the insurer can discriminate perfectly between risky patents; (ii) coverage is voluntary and the insurer cannot discriminate between patents, and (iii) coverage is compulsory. The model highlights a set of peculiar strategic characteristics of insurance for legal expenditures which contribute to singling out the reasons underlying the underdevelopment of this market. We suggest that the crucial reason for such a failure is not adverse selection; consequently, we challenge the benefits of making coverage compulsory. 相似文献

In this paper we revisit Tullock's paradox (Tullock, 1980) and consider a rent-seeking game in which parties face increasing returns to effort. We allow parties to randomize their strategies and give them an exit option. Given the mixed participation strategies of the parties, valuable rents may occasionally remain unexploited. We consider such a lost-treasure effect as an additional cost of rent seeking and examine how the expected value of such a lost rent varies with changes in the parameters of the problem. 相似文献

The claim that in policy games nonneutrality and a stagflation bias emerge in equilibrium if the unions care about inflation, per se, is discussed. This assumption is shown to be not necessary to obtain a stagflation bias; the same applies to nonneutrality if a government acts in the economy. The question of whether unions should be envisaged as “institutions” (i.e., interested in variables unrelated to wages and employment) is also addressed. Two model-based alternatives providing “microeconomic” foundations versus “macroeconomic” foundations to unions' behaviour are presented. The conclusion is that the modelling of unions remains an unsettled problem. 相似文献
