论法国现代主义文学中的死亡主题

对死亡的思考，不仅是基督教文化的传统，而且是现代西方哲学各派，尤其是存在主义哲学所关注的问题。法国文学对死亡的探索是希望能够超越死亡，以实现生命的不朽，使人们漂泊无依的灵魂得到安置，使其在形而上的意义上获得永生。     

On the differences in measuring SMB and HML in the UK – Do they matter?

The Fama–French (FF) three factor model expands the capital asset pricing model (CAPM) to include two additional factors to the market factor – SMB, employed to capture a firm size effect in returns and HML employed to capture book-to-market effects in returns. In the UK, different researchers use different ways of calculating SMB and HML in the context of empirical applications of the three factor model, or extensions of it, perhaps because they believe the differences in the construction of the SMB and HML factors to be relatively unimportant from an empirical standpoint. We investigate whether indeed factor construction methods are unimportant. Our conclusion is that they do matter.     

Predicting credit card fraud with Sarbanes‐Oxley assessments and Fama‐French risk factors

This research developed and tested machine learning models to predict significant credit card fraud in corporate systems using Sarbanes‐Oxley (SOX) reports, news reports of breaches and Fama‐French risk factors (FF). Exploratory analysis found that SOX information predicted several types of security breaches, with the strongest performance in predicting credit card fraud. A systematic tuning of hyperparamters for a suite of machine learning models, starting with a random forest, an extremely‐randomized forest, a random grid of gradient boosting machines (GBMs), a random grid of deep neural nets, a fixed grid of general linear models where assembled into two trained stacked ensemble models optimized for F1 performance; an ensemble that contained all the models, and an ensemble containing just the best performing model from each algorithm class. Tuned GBMs performed best under all conditions. Without FF, models yielded an AUC of 99.3% and closeness of the training and validation matrices confirm that the model is robust. The most important predictors were firm specific, as would be expected, since control weaknesses vary at the firm level. Audit firm fees were the most important non‐firm‐specific predictors. Adding FF to the model rendered perfect prediction (100%) in the trained confusion matrix and AUC of 99.8%. The most important predictors of credit card fraud were the FF coefficient for the High book‐to‐market ratio Minus Low factor. The second most influential variable was the year of reporting, and third most important was the Fama‐French 3‐factor model R² – together these described most of the variance in credit card fraud occurrence. In all cases the four major SOX specific opinions rendered by auditors and the signed SOX report had little predictive influence.     

批判与继承:二战后法国的地缘政治思想

20世纪60年代末至70年代初,法国国际影响力的大幅衰落、西欧一体化进程的发展以及战后经济社会危机的出现,为法国地缘政治研究的复兴创造了历史与社会背景。在其后几十年时间里,法国地缘政治学者在激烈批判传统地缘政治本体论、认识论及其历史影响的基础上,通过继承法国传统政治地理学的一些基本方法主张,针对20世纪下半叶世界政治发展呈现的诸多问题,在相当广泛的议程上展开了考察。二战后的法国地缘政治思想以其注重文化解读、关注个案分析、拒斥理论归纳的情调风格以及在国际合作、一体化条件下民族国家的地位作用、对广大第三世界国家的案例分析等项议题上的研究,体现出鲜明的法国特色与法国立场,具有广泛的学术与社会影响,为当代地缘政治研究的发展做出了一定的贡献。     

中国资本市场的中长期动量效应和反转效应——基于Fama和French三因素模型的进一步研究

基于国内外学者对于中国股票市场的动量效应和反转效应的研究,利用1994~2004年中国股票市场的经验数据,借助于Fama和French的三因素模型,对中国股市的动量和反转效应进行解释。研究结果表明,Fama和French三因素模型的解释力度不大。     

Three decades of productivity change in French beef production: a Färe‐Primont index decomposition

The Färe‐Primont index is used to evaluate total factor productivity (TFP) change and its components for a sample of French suckler cow farms in grassland areas in 1985–2014. The results reveal an increase in TFP of 6.6 per cent over the whole observation period, with technological progress being the major source of productivity growth. Meanwhile, efficiency decreased. Farms experienced great technological progress from 1991 to 2000. From a methodological point of view, the comparison with results obtained with Malmquist indexes shows similar trends but different magnitudes, with the Malmquist index overestimating the TFP and technological changes compared to the Färe‐Primont index. In addition, the use of a sequential approach that restricts technological change to being positive or null allows for the precise calculation of technology changes, disregarding the effects of external conditions that are captured in efficiency changes. Finally, the estimation of full dimensional efficient facets (FDEFs) that guarantees the positivity of all shadow prices used to assess the mix efficiency component of TFP change is promising.     

法语介词depuis、pendant和pour用法之比较

初学法语的人一般都会受累于法语复杂的语法和众多的动词变位,因为这两者确实给初学者带来大量的记忆工作。相对而言对于初学者来说,介词的学习似乎要轻松一点,尤其是对于那些学过英语的人来说,某些法语介词的用法与英语相似;但其实不然,随着学习的深入,学习者会发现法语中有不少介词其用法类似,从而非常容易混淆：有时是因为两个不同介词的用法有微小的不同,难以区分;有时是因为语言上的习惯,固定的搭配,只能靠记忆。这里我们就着重分析区别三个表示时间的用法类似的简单词形介词。     

The French commitment to European monetary integration: A review of the two EMS crises (1981–83, 1992–93)

This paper focuses on the process of exchange rate management during the two European Monetary System(EMS) crises, in 1981–83 and 1992–93, and examines the factors which led the French governments to adhere to the EMS. France's strong franc (franc fort) policy is a useful test case for maintaining national commitment to European monetary integration. The origin of the franc fort policy can be traced back to the exchange rate crisis of 1981–83. By actively supporting European institutions and emphasizing the emergence of a strong and united European common currency, France discovered the way to bolster confidence in her economic policy. Beyond this focal point, political justification and economic rationality became mutually reinforcing, configuring French national preference in European monetary integration. The response of the French government to the EMS crisis of 1992–93 was more consistent compared to the response to the 1981–83 crisis, and reflected the accumulation of loyalty to European monetary integration. This loyalty, however, was made neither from purely economic calculation nor out of normative commitment French European monetary policy reflected the interaction between domestic politics and European monetary integration. The French commitment to the franc fort also was based on domestic political bases such as the existence of a core policy group, a centralized policy‐making structure, and an issue linkage between the franc fort and European integration.     

Estimating persistent and transient technical efficiency and their determinants in the presence of heterogeneity and endogeneity

We develop an estimation procedure that generates consistent estimates of the technology parameters, long-run (persistent) and short-run (transient) technical inefficiencies and the marginal effects of their determinants for the stochastic frontier model developed by Colombi et al. (2014, Journal of Productivity Analysis 42, 123) and Kumbhakar et al. (2014, Journal of Productivity Analysis 41, 321). Our approach accounts for three sources of potential endogeneity: (i) unobserved heterogeneity; (ii) simultaneity of input use with both types of technical efficiency; (iii) potential correlation of the noise term with the regressors. Using this approach we examine the effect of direct payments and farm size on the persistent and transient technical efficiency of French crop farms before and after the European Union's Common Agricultural Policy decoupling reform of 2003. Our results show that subsidy payments per hectare of utilised agricultural land had a significant positive effect on persistent technical efficiency and a significant negative effect on transient technical efficiency during the period before decoupling. For the period after the reform, the effect of subsidies is found to be significantly negative for persistent technical efficiency and insignificant for transient technical efficiency. The overall effect of subsidies on technical efficiency is found to be negative in both periods, albeit substantially lower in the period after decoupling. The effect of farm size on technical efficiency is found to be significant only for the period prior to the reform: it reduced persistent technical inefficiency but increased transient technical inefficiency during that period.
