Current mobility management solutions based on ID/Locator separation are not easily deployed and cannot solve routing scalability and mobility problems. This paper proposes a novel network architecture based on ID/Locator separation and suggests a new mobility management solution. This solution solves the problem of scalability in the network and also provides better support for mobility. It can be easily deployed because no modification of the mobile host’s protocol stack is required. The identifier contains some routing information; so the solution provides intrinsic interworking with traditional mobile hosts. Because the mapping systems are distributed to the edge networks, robustness of the whole system is enhanced and handover delay is decreased. 展开更多

The development of waste management can be considered in some way dictates of time. Ukraine has unique conditions of the secondary usage of natural resources, which is particularly important given to the increasing generation of waste and its progressive accumulation. The relevant provisions relate to the industrial sector as well as areas of consumption. However, for most of recyclable materials is still low. The formation of market relations in Ukraine contributed to enhance this process and relevant field of entrepreneurship. Now the formation of a separate segment is taking place. The state and the perspectives of the development of collection, accumulation and recycling of waste stream have been analyzed in the article. Conceptual position of the legislative regulation of this field is defined. The ways of improving the legal support of secondary raw materials have been defined. The peculiarities of waste management of Ukraine are considered. 展开更多

Lithium metal batteries(LMBs)have been extensively investigated during the past decades because of their ultrahigh energy densities.With the increasing demand for energy density,however,the safety issue of LMBs has become a significant challenge.In particular,localized areas of increased temperature(namely,hotspots)may be induced and even exacerbated within LMBs by uneven current distribution,internal short circuits,or inadequate heat dissipation,which significantly sacrifices battery safety and cycle life.Here,we report the rational design and fabrication of a fast thermal responsive separator capable of inhibiting the growth of lithium dendrites and mitigating thermal propagation,thereby reducing the risk of thermal runaway.The as-achieved separator comprises both an electrospun membrane using a phase change material with superior thermal-storage ability and a thermally conductive modification layer of hexagonal boron nitride nanosheets with a fast heat-transfer feature.It is demonstrated that such a unique integration of heat conduction and heat storage enables the functional separator with attractive abilities to mitigate hotspots and inhibit the growth of lithium dendrites upon the cycling of LMBs.Moreover,pouch cells with the thermal-responsive separator,as well as numerical simulations,verify much enhanced safety and cycle life of LMBs.This work may offer a new conceptual design of intelligent separators that acts as a functional unit encapsulated within a single cell to boost in-situ thermal management,which will help to develop high-safety and energy-dense LMBs. 展开更多

This study investigates the earnings performance of 418 initial public offerings (IPOs) listed on the stock exchange of Hong Kong. By analyzing several profitability measures of these 1PO companies from the third year prior to listing up to the fifth year post-listing, it is found that IPO companies' operating performances as a whole peak in the year of listing or the year preceding the listing, but exhibit a fall in post-issue profitability with the decline being most pronounced in the first financial year following the year in which the listing take place. Over 30% of these IPOs suffer a loss three years after the offerings. Deterioration of post-issue performance is found to be more severe for smaller finns, highly-geared companies, fast-growing enterprises, companies with lower ownership retention by original shareholders, and companies which have managed earnings upwards at the time of listing. These observations are consistent with the higher agency costs when firms go public and that managers have timed the issue at the peak of the companies' long-run performance. Further investigation confirms that IPO companies in general make use of income-increasing accruals to manage their earnings upwards in the year when they go public. The reversal of the accruals in post-issue years further exaggerates the decline in their profitability. 展开更多

Purpose: Optimal pain management strategies for patients undergoing component separation hernia repair are not defined. Epidural analgesia (EA) has been shown to decrease pulmonary complications and duration of ileus and to improve pain control in other patient populations. In this study we examined outcomes of patients receiving EA after separation of components (SOC). Methods: After obtaining IRB approval, a retrospective review was performed of patients undergoing ventral hernia repair with SOC from January 2006 to October 2010 at the University of Kentucky. Patients were identified from hospital operative records. Pre-operative patient characteristics and operative data were obtained from the medical record. Information was collected relating to use of EA, complications, and length of hospitalization (LOS). Post-operative outcomes were compared between those that had epidurals and those that did not. Results: One hundred seventeen patients were identified that underwent SOC, 34 of whom had EA. These two groups were similar in relation to age, BMI, and co-morbidities. Three patients in the epidural group had complications limiting epidural duration—two with hypotension and one with refractory pruritus. There was no difference in pneumonia, deep vein thrombosis (DVT), wound infection, urinary tract infection (UTI), recurrence, or mortality (Table 1). There was an increase in LOS (6.68 vs. 6.06 days, p 0.01) in patients with EA. Conclusions: The use of EA results in increased LOS in patients undergoing SOC. EA associated morbidity occurs infrequently. The incidence of post-operative complications is unaffected by EA. Further studies are needed to delineate the benefit of EA in this patient population. 展开更多

Source separation is the basic premise for making effective use of household wastes. In eight cities of China, how- ever, several pilot projects of source separation finally failed because of the poor participation rate of residents. In order to solve this problem, identifying those factors that influence residents’ behavior of source separation becomes crucial. By means of questionnaire survey, we conducted descriptive analysis and ex- ploratory factor analysis. The results show that trouble-feeling, moral notion, environment protection, public education, environment value and knowledge deficiency are the main factors that play an important role for residents in deciding to separate their household wastes. Also, according to the contribution percentage of the six main factors to the total behavior of source separation, their influencing power is analyzed, which will provide suggestions on household waste management for policy makers and decision makers in China. 展开更多

The utilization of bioorganic municipal waste (BMW) is considered essentially for the further development of integrated waste management practice in China. Awareness and knowledge about the importance of BMW management and source separation of waste on household level, as a precondition for the implementation of an economically feasible integrated waste management infrastructure, were developed in Europe during the last decade. The Sino–German RRUBMW Project is facilitating applied research investigations in 4 pilot areas in Shenyang to assess the population’s behavior to develop the design criteria for appropriate process technologies and to provide the basis to adopt BMW management policy in China. 展开更多

Based on the behavioral finance theory and the upper echelons theory, this paper employs the data of China's A-share listed companies from 2008 to 2013 as research samples, and empirically tests the effects of managers with different characteristics on debt financing and firm value for enterprises of different ownership nature. Results of this study indicate that the debt financing of the listed companies in China can reduce the agency cost with a positive governance effect that promotes firm value. Male, better educated, short-tenured, and financially experienced managers are more likely to be overconfident and prefer debt financing. Specifically, the manager's age, level of education, and work experience can significantly promote the effect of debt financing on firm value. Compared with SOEs, private enterprises can improve their firm value more significantly through debt financing;the education and work experience of the managers of private enterprises are more positively correlated with debt financing and can more significantly improve firm value through debt financing. This paper's findings suggest that the manager's characteristics and firm ownership nature must be taken into account to reach valid conclusions on the governance effects of debt financing on firm value. Meanwhile, these conclusions help unravel the mechanism and economic implications of debt financing, and contribute to the improvement of the capital structure decisions and human resources management practices of China's listed companies. This study not only enriches the literature and empirical evidence on the correlation between managers' characteristics and firm financing, but indicate that managers' characteristics and firm ownership are important considerations for investigating the governance effects of debt financing on firm value and have a vital impact on the formulation and implementation of firm financing decisions. 展开更多
