Why Do Experienced Challengers Do Better than Amateurs?

Politically experienced challengers are more successful in seeking political office than amateurs. The relationship is found so regularly that political experience has become the standard ex ante indicator of challenger quality in studies of American elections. Despite this, little work has investigated why experienced challengers are so successful. Many scholars attribute the relationship to inherent differences between experienced challengers and amateurs: experienced challengers have stronger electoral skills and greater access to material resources. I argue that these differences play a role, but an indirect one. Rather, experienced challengers are lead by both their resource advantage and the high amount of risk they are exposed to in seeking office to run in races in which their party has a good chance of winning. Thus, the direct cause of the experienced challengers’ success is self-selection into winnable races. Empirical analysis supports the self-selection model over a model in which resources directly lead to success.

试论我国传统孝道的现代涵义

“孝”是中华民族的传统美德,如何继承和发扬传统“孝道”是中国现代家庭文明建没必须要回答和解决的一大课题。本文通过对我国传统“孝道”的辩证分析,指出“孝”是一个优弊共存的“杂糅体”,既有其适应时代发展的合理性因素,又有其阻碍社会发展的局限性,在当今时代,人们应当树立一种崭新的“孝道”观念、“养亲”、“敬亲”、“谏亲”应是现代“孝”道的主要涵义和内容。

An overview: A new era of tax enforcement – from “big stick” to responsive regulation

Recent developments in regulation and tax administration in Australia inspired this article on tax compliance and responsive regulation. This article analyzes the economics of crime and compliance as the dominant approach to tax enforcement of the past three and a half decades. It evaluates the key advantages and disadvantages of the economic approach as well as its application to tax. The article then explores responsive regulation as an alternative method that draws on the economic paradigm but also supplements this approach with other theories, particularly those involving identity, conflict escalation, and procedural justice. Building on this analysis and a case study of Australian investors in mass marketed tax schemes, the article suggests that the broader, more balanced, and closely tailored method of regulating responsively may enable regulators to draw on the advantages of the economic model while alleviating some of its drawbacks. Responsive regulation may therefore constitute a superior method for regulating compliance.     

Limits to non‐state market regulation: A qualitative comparative analysis of the international sport footwear industry and the Fair Labor Association

Non‐state market regulation has become a central focus and continues to receive scholarly attention. The present paper provides an assessment of the conditions under which multinational firms join a multi‐stakeholder certification initiative. The cases of the Fair labor Association and 17 international sport footwear companies have been selected for this purpose. A Qualitative Comparative Analysis of the 17 cases is performed. The paper argues that the combination of sustained NGO pressure and public ownership of a firm is a necessary precondition for firms joining a multi‐stakeholder certification initiative. The theoretical and policy implications of this result are discussed.

委托理财协议中的保底条款效力之追问

保底条款是委托理财协议中最重要的条款,它不仅决定了这种投资方式的存在与否,同时亦是委托理财失败诉争时当事双方相持不下的根本原因。对于该条款的效力认定,目前的法律与司法实践并没有提供能真正能起到指导与评价作用的答案。因此,从合同的私法性、社会法性及保底条款与其它条款的勾连角度来追问保底条款的效力问题是合理与适法判决的关键所在。     

Fingerprint analysis for the determination of hand origin (right/left) using the axis slant in whorl patterns

Fingerprints are frequently encountered during both civil and criminal investigations. Fingerprints possess numerous characteristics that assist with personal identification. Determining the hand of origin (right or left) for an individual fingerprint would help reduce investigation time and potentially eliminate certain suspects. In this study, we collected a total of 2 900 single digit fingerprints from 290 individuals, and the whorl axis slant was examined in the 743 whorl pattern fingerprints (385 from the right hand and 358 from the left hand). A slant towards the right side was present in 81.82% of samples from the right hand, while a slant towards the left side was observed in 80.73% of samples from the left hand. After applying a chi-square test to the dataset, the results were found to be statistically significant for the determination of hand origin. Our results suggest that the whorl axis slant in a fingerprint is indicative of hand origin (right or left).

Key points

• Single digit fingerprints with whorl pattern were analyzed.
• Whorl “axis slant” was used to determine the hand origin.
• Right axis slant would indicate the right hand of the print.
• Left axis slant would indicate the left hand of the print.

     

Analysis of sensitivity and specificity: precise recognition of neutrophils during regeneration of contused skeletal muscle in rats

In this report, we applied the TissueFAXS 200 digital pathological analysis system to rapidly and accurately identify neutrophils during regeneration of contused skeletal muscle, and to provide information for follow-up studies on neutrophils to estimate wound age. Rat injury model was established, and skeletal muscle samples were obtained from the control group and contusion groups at 1, 1.5, 2, 3, 4, and 6 h, as well as at 1, 3, 5, and 15 d post-injury (n = 5 per group). The expression of nuclei and neutrophils was detected by hematoxylin and eosin (HE) staining and immunohistochemical (IHC) staining. A total of 20 injury site areas of 0.25 mm² (0.5 mm × 0.5 mm) were then randomly selected at all time points. A TissueFAXS 200 digital pathological analysis system was used to identify the positive and negative numbers. Knowledge of five professional medical workers were considered the gold standard to measure the false positive rate (FPR), false negative rate (FNR), sensitivity, specificity, and area under the curve (AUC) of receiver operating characteristic (ROC) curves. As a result, with a staining area of neutrophils from 8 µm² to 15 µm², the FPR was 4.28%–12.14%, the FNR was 12.42%–64.08%, the sensitivity was 35.92%–87.58%, the specificity was 87.86%–95.72%, the Youden index was 0.316–0.754, the accuracy was 82.80%–88.30%, and the AUC was 0.771–0.826. The AUC was largest when the cut-off value of the staining area was 12 µm². Our results show that this software-based method is more accurate than the human eye in evaluating neutrophil infiltration. Based on the sensitivity and specificity, neutrophils can be accurately identified during regeneration of contused skeletal muscle. The TissueFAXS 200 digital pathological analysis system can also be used to optimize conditions for different cell types under various injury conditions to determine the optimal cut-off value of the staining area and provide optimal conditions for further study. Furthermore, it will provide evidence for forensic pathology cases.
