Estimation of treatment effects for heterogeneous matched‐pairs data with probit models

Estimating the effect of medical treatments on subject responses is one of the crucial problems in medical research. Matched‐pairs designs are commonly implemented in the field of medical research to eliminate confounding and improve efficiency. In this article, new estimators of treatment effects for heterogeneous matched‐pairs data are proposed. Asymptotic properties of the proposed estimators are derived. Simulation studies show that the proposed estimators have some advantages over the famous Heckman's estimator, the conditional maximum likelihood estimator, and the inverse probability weighted estimator. We apply the proposed methodology to a data set from a study of low‐birth‐weight infants.     

The generalized Poisson-binomial distribution and the computation of its distribution function

The Poisson-binomial distribution is useful in many applied problems in engineering, actuarial science and data mining. The Poisson-binomial distribution models the distribution of the sum of independent but non-identically distributed random indicators whose success probabilities vary. In this paper, we extend the Poisson-binomial distribution to a generalized Poisson-binomial (GPB) distribution. The GPB distribution corresponds to the case where the random indicators are replaced by two-point random variables, which can take two arbitrary values instead of 0 and 1 as in the case of random indicators. The GPB distribution has found applications in many areas such as voting theory, actuarial science, warranty prediction and probability theory. As the GPB distribution has not been studied in detail so far, we introduce this distribution first and then derive its theoretical properties. We develop an efficient algorithm for the computation of its distribution function, using the fast Fourier transform. We test the accuracy of the developed algorithm by comparing it with enumeration-based exact method and the results from the binomial distribution. We also study the computational time of the algorithm under various parameter settings. Finally, we discuss the factors affecting the computational efficiency of the proposed algorithm and illustrate the use of the software package.     

Are good governance principles institutionalised with policy transfer? An examination of public–private partnerships policy promotion in China

This article explores the following question: To what extent are good governance principles being institutionalised in China as a result of public–private partnerships (PPP) policy transfer? Since 2013, China has been pursuing PPP and applying aspects of related good governance drawing from Western experience despite its radically different fragmented authoritarian regime. This makes China a unique case to observe the extent to which good governance principles can be institutionalised in very different contexts. This article assesses the degree of institutionalisation of three good governance principles that guide PPP policy elsewhere: transparency and accountability, willingness to collaborate and equity between partners. It argues that while the PPP policies have been applied extensively in recent years, these good governance principles have been institutionalised to varying degrees as they have had to be adapted and compromised to fit with existing power relations in authoritarian China. The findings aim to add value to the literature regarding PPP policy transfer and good governance, by revealing the challenges of institutionalising good governance principles through PPP policy transfer in an alien context.

古希腊悲剧功能的诗学阐释——以《俄狄浦斯王》为例

亚里士多德的"净化"说是关于悲剧功能的权威诗学解释,黑格尔的"和解"说和尼采的"形而上的慰藉"说都是亚氏诗学解释的展开和延伸。文章以被亚氏誉为悲剧典范的《俄狄浦斯王》为参照,讨论亚氏、黑格尔和尼采等人对悲剧功能的阐释,以期加深对古希腊悲剧的观照和理解。     

Facilitating Redundancy‐Oriented Management with Gene‐Therapy‐Oriented Management Against Disaster

This article tests the hypothesis that “if redundancy‐oriented management has negative aspects, then it could be facilitated by gene‐therapy‐oriented management.” Negative aspects include disadvantages, misjudgments, or miscalculations. The article provides a newly revised principle of disaster management by studying gene‐therapy‐oriented management. Based on qualitative analysis, redundancy‐oriented and gene‐therapy‐oriented management are analyzed via five variables: governments, business, volunteers, households, and the international community. The article is valuable because an analytical frame on gene‐therapy‐oriented management is systematically reconceptualized for the field of disaster management via three elements: unhealthy proteins (problems or failed measures), a vector (new or modified solutions), and target cells (positive outcomes). In accepting the hypothesis, the key tenet is that stakeholders have to assist the progress of redundancy‐oriented management with gene‐therapy‐oriented management by paying attention to the genes of each disaster.     

Discourse Failures and the NGO Sector: How Campaigning Can Undermine Advocacy

Within academic research, more and more scholars reveal the ambivalence of NGOs—the sometimes constructive, sometimes destructive role they play in solving societal problems. In this paper, we present a discourse analysis that illustrates how NGOs’ campaigning may undermine their reputation and advocacy function. We conclude that such discourse failures are frequently not merely an accidental by-product, but rather a not-intended consequence of deliberate NGOs’ campaigns. By applying ideas from political economy, we make particular note of probable discourse failures when campaigns attempt to deal with complex issues in an environment rife with wide-spread prejudices and where the NGO’s work is transparent. We present collectively institutionalized commitments for NGOs and commitment services enforced by political organizations as instruments that are suitable for increasing public accountability of the NGO sector. In conclusion, we argue that further research can benefit from systematically analyzing the interdependencies between discourses and institutions.     

Detecting fuzzy periodic patterns in futures spreads

This paper extends an optimal frequency domain test for the detection of synchronous patterns in multiple time series to the case of fuzzy patterns, which are not confined to single frequencies or narrow frequency bands. Applying this extension to corn futures with different delivery dates, we obtain significant results only for the spreads between the different contracts but not for the original contracts, which is an indication that spread trading has the advantage of increased predictability.
