This study empirically demonstrates the efficacy of a two-level Dirichlet-multinomial statistical model (the Multinomial system) for computing likelihood ratios (LR) for linguistic, textual evidence with multiple stylometric feature types with discrete values. The LRs are calculated separately for each feature type, namely, word, character and part of speech N-grams (N = 1,2,3), which are combined as overall LRs through logistic regression fusion. The Multinomial system’s performance is compared with that of a previously proposed system with the cosine distance (the Cosine system) using the same data (i.e., documents collated from 2160 authors). The experimental results show that: (1) the Multinomial system outperforms the Cosine system with the fused feature types by a log-LR cost of ca. 0.01 ~ 0.05 bits; and (2) the Multinomial system is more advantageous in performance with longer documents than the Cosine system. Although the Cosine system is more robust overall against the sampling variability arising from the number of authors included in the reference and calibration databases, the Multinomial system can achieve reasonable stability in performance; for example, the standard deviation value of the log-LR cost becomes lower than 0.01 (10 random samplings of authors for the reference and calibration databases) with 60 or more authors in each database. 相似文献

This study explored whether the rational (certainty of punishment) and nonrational (criminal thinking) aspects of antisocial decision‐making interact. A convenience sample of 319 undergraduates (106 men, 213 women) completed a measure of criminal thinking and responded to three fictional vignettes (i.e., cheating on a final examination in a class they were in jeopardy of failing, stealing $50 off a table in a dorm room, and selling marijuana for a friend) at three different levels of risk or certainty of apprehension (50%, 10%, and 1%). Results indicated that participants reported that they would be more likely to engage in antisocial behavior when the certainty of getting caught was low and the level of proactive (P) or reactive (R) criminal thinking was high. An interaction between certainty and criminal thinking was also observed in which the gap between lower and higher criminal thinking respondents grew as the probability of getting caught fell. 相似文献

Following an introduction to the changes in how ethno-racial identity is conceptualized in the social sciences and humanities by the destabilization of categorical frameworks, the author looks at how law reacts to these discussions and paradigm shifts, and argues that legal and administrative approaches face severe linguistic and conceptual limitations by operating within a “choice” and “fraud” binary. The article then questions if the free choice of identity exists as a principle of international minority protection law, a legal field that arguably represents a global political and ethical consensus. The author makes two claims. First, according to the basic tenet of legal logic, a proper right to free choice of identity allowing people to opt out of racial, ethnic, or national (minority) communities would necessitate the freedom to opt in to the majority or to any chosen group. The second claim, however, is that international law would not actually construct an approach to opting in. Thus, the right to free choice of identity is not an autonomous, sui generis right under international law. 相似文献

Decades of research has found that voters’ electoral decisions to a significant degree are affected by character evaluations of candidates. Yet it remains unresolved which specific candidate traits voters find most important. In political science it is often argued that competence-related traits are most influential, whereas work in social psychology suggests that warmth-related traits are more influential. Here we test which character trait is the more influential in global candidate evaluations and vote choice using observational data from the ANES 1984–2008 and an original experiment conducted on a representative sample of English partisan respondents. Across the two studies we find that warmth is more influential than competence, leadership and integrity. Importantly, results hold across a wide range of alternative specifications and robustness analyses. We conclude by discussing theoretical and practical implications of the results. 相似文献

The European Union (EU) Member States in central and eastern Europe (CEE) witnessed a surge in outward foreign direct investment (OFDI) between 2000 and the start of the global financial crisis. This article investigates whether the European integration process altered the relative importance of host country location factors. In particular, we investigate to what extent knowledge‐seeking is a relevant investment motive, which has been documented as a key determinant for OFDI from other emerging economies. We apply a discrete choice approach to model foreign location choice of firms from CEE countries (CEECs) within the EU 27 (1996–2010). We find that the EU integration process is related with increasing importance of market access and less emphasis on labour cost advantages. We find heterogeneity in the valuation of foreign knowledge‐related assets. The location probability within the EU15 is positively associated with knowledge‐seeking. It also plays a role for technology‐intensive industries and larger firms. 相似文献

孟子对舜的诸多论述体现出独特的观念:首先,孝作为一种道德原则源于人的本性之善。其次,孝是具有最高价值的道德原则,它不仅能够实现于血亲关系和家庭中,也可推及于社会群体及天地万物,具有强大的示范与感化作用。再次,在具体的实践方式上,为人子者应顺乎父母、得乎父母,对父母时时保持发诸本心的诚与敬。最后,在不同的道德原则发生冲突时,应根据具体情境选择具有更高价值的道德原则作为判断与选择的标准,做到原则性与灵活性的统一。 相似文献

The impact of local campaigning on voter choice has been studied within the theme of mobilisation. Grassroots effort can attract votes efficiently, but campaign contact is (potentially) endogenous, so results showing positive effects could be flawed. Experimental solutions to this problem are possible, but could also have low external validity. Drawing on the electoral geography literature, this article suggests that endogeneity concerns can be addressed through so‐called ‘friends and neighbours voting’. One source of endogeneity is that that candidates may tend to canvass those living close to their own homes, and those canvassed would be expected in any case to be prone to support local candidates. The problem of endogeneity is reframed and treated as an omitted variable bias. Using unique Irish data on the geographic location of the homes of candidates, as well as data on the location of the voters, the analysis confirms that canvassing has a positive impact on candidate choice independent of the effect of geographic distance. More importantly, these two variables interact. The results point to the relevance of the geographic dimension of electoral politics in driving the endogeneity bias in local campaigning studies. 相似文献
