在辛亥上海光复过程中,光复会第三号领袖人物李燮和的功劳最大,但他在随后争夺沪军都督时首先被排挤出局,则是他自身诸多不足所造成的。李燮和在辛亥上海光复过程中所表现出来的不计个人名利得失、顾全革命大局的高姿态值得大书一笔,这是整个辛亥革命史上的一个亮点。后来的国民党官方史学家们以李燮和后来参加“筹安会”为口实,刻意贬低李燮和在上海光复中的作用与贡献,是站不住脚的,也是不足取的。 相似文献

通过对归入权行使对象、行使主体、行使范围的论述 ,对《证券法》第 42条的修改提出了相关建议 :归入权行使对象应当扩大 ,行使主体不仅应包括董事会、监事会、股东 ,在一定条件下 ,证监会也可以作为行使主体。在计算归入权的收益上可采取最高卖价减最低买价法予以计算。 相似文献

In this study we investigate the desired level of recovery under various inventory control policies when the success of recovery is probabilistic. All the used and returned items go into a recovery process that is modelled as a single stage operation. The recovery effort is represented by the expected time spent for it. The effect of increasing recovery effort on the success probability together with unit cost of the operation is included by assuming general forms of dependencies. Alternative to recovered items, demand is satisfied by brand-new items. Four inventory control policies that differ in timing of and information used in purchasing decision are proposed. The objective is to find the recovery level together with inventory control parameter that minimize the long-run average total cost. A numerical study covering a wide range of system parameters is carried out. Finally computational results are presented with their managerial implications. 相似文献

In this article, an agent‐based framework to quantify the seismic resilience of an electric power supply system (EPSS) and the community it serves is presented. Within the framework, the loss and restoration of the EPSS power generation and delivery capacity and of the power demand from the served community are used to assess the electric power deficit during the damage absorption and recovery processes. Damage to the components of the EPSS and of the community‐built environment is evaluated using the seismic fragility functions. The restoration of the community electric power demand is evaluated using the seismic recovery functions. However, the postearthquake EPSS recovery process is modeled using an agent‐based model with two agents, the EPSS Operator and the Community Administrator. The resilience of the EPSS–community system is quantified using direct, EPSS‐related, societal, and community‐related indicators. Parametric studies are carried out to quantify the influence of different seismic hazard scenarios, agent characteristics, and power dispatch strategies on the EPSS–community seismic resilience. The use of the agent‐based modeling framework enabled a rational formulation of the postearthquake recovery phase and highlighted the interaction between the EPSS and the community in the recovery process not quantified in resilience models developed to date. Furthermore, it shows that the resilience of different community sectors can be enhanced by different power dispatch strategies. The proposed agent‐based EPSS–community system resilience quantification framework can be used to develop better community and infrastructure system risk governance policies. 相似文献

Housing recovery is an unequal and complex process presumed to occur in four stages: emergency shelter, temporary shelter, temporary housing, and permanent housing. This work questions the four-stage typology and examines how different types of shelter align with multiple housing recovery stages given different levels of social vulnerability. This article also presents a Markov chain model of the postdisaster housing recovery process that focuses on the experience of the household. The model predicts the sequence and timing of a household going through housing recovery, capturing households that end in either permanent housing or a fifth possible stage of failure. The probability of a household transitioning through the stages is computed using a transition probability matrix (TPM). The TPM is assembled using proposed transition probability models that vary with the social vulnerability of the household. Monte Carlo techniques are applied to demonstrate the range of sequences and timing that households experience going through the housing recovery process. A set of computational rules are established for sending a household to the fifth stage, representing a household languishing in unstable housing. This predictive model is exemplified on a virtual community, Centerville, where following a severe earthquake scenario, differences in housing recovery times exceed four years. The Centerville analysis results in nearly 5% of households languishing in unstable housing, thereby failing to reach housing recovery. These findings highlight the disparate trajectories experienced by households with different levels of social vulnerability. Recommendations are provided at the end for more equitable postdisaster recovery policies. 相似文献

《Journal of Social Work Practice》2012,26(4):475-487
This article examines a central plank of mental health policy (‘recovery’) in societies which have attempted to reverse the long-term warehousing of those with a diagnosis of mental disorder (de-institutionalisation). The emergence of the concept is traced in relation to the shift from an institutional to a more dispersed and community-based form of service organisation. Different usages of the term ‘recovery’, each with distinct implications for practice are considered on the part of three main interest groups (traditional bio-medical psychiatrists; social psychiatrists emphasising social skills training; and dissenting service users). These different usages suggest that ‘recovery’ is a polyvalent concept that creates an uneasy consensus point to define the management philosophies of local services enacting mental health policy. Also mental health work is about more than the group of patients mainly considered in relation to recovery (those with ‘severe and enduring mental health problems’). Practice-near research strategies are now required to investigate the varied practical scenarios these contradictions generate and ethnographic research is therefore indicated. Without multiple ethnographies, we will be left with competing rhetoric about recovery and its meaning or meanings may be rendered worthless. 相似文献
