Equivalences Among Polarity Algorithms

The concept of polarity is pervasive in natural language. It relates syntax, semantics and pragmatics narrowly (Giannakidou, in: Maienborn, von Heusinger, Portner (eds.), Semantics: an international handbook of natural language meaning, De Gruyter Mouton, Berlin, 2011; Israel in The grammar of polarity: pragmatics, sensitivity, and the logic of scales, Cambridge studies in linguistics, Cambridge University Press, Cambridge, 2014), it refers to items of many syntactic categories such as nouns, verbs and adverbs. Neutral polarity items appear in affirmative and negative sentences, negative polarity items cannot appear in affirmative sentences, and positive polarity items cannot appear in negative sentences. A way of reasoning in Natural Language is through Natural Logic (van Benthem in Essays in logical semantics, vol. 29 of Studies in linguistics and philosophy, Reidel, Dordrecht, 1986; Language in action: categories, lambdas, and dynamic logic, vol. 130 of Studies in logic, Elsevier, Amsterdam, 1991). This logic is based on the concept of polarity in order to make the meaning of a sentence weaker o stronger without changing its truth value. There exist many proposals to compute polarity in the Natural Logic context, the most widely known are the ones by: van Benthem (1986, 1991), Sánchez-Valencia (Studies on natural logic and categorial grammar, Ph.D. thesis, Universiteit van Amsterdam, 1991), Dowty (Proceedings of the 4th conference on semantics and theoretical linguistics, Cornel University, CLC Publications, Rochester, 1994), and van Eijck (in: ten Cate, Zeevat (eds.), 6th international Tbilisi symposium on logic, language, and computation, Batumi, Georgia, Springer, 2007). If Natural Logic is going to be used, as an inferential mechanism between text fragments, in Natural Language Processing applications such as text summarization, question answering, and information extraction, it is a priority to know what the existing relationship among the aforementioned algorithms is; for example, to implement the most general. We show in this paper the equivalence among the analyzed algorithms, filling a gap in Natural Logic research, particularly in computing polarity, and the soundness of their algorithms.     

Maternal Reports of Play Dates of Clinic Referred and Community Children

Recent interventions have focused upon play dates as a means to improve friendships. However, no measures have been published which quantify play date quality. An important characteristic of play dates in this regard may be the amount of conflict. We present the development of such a measure. We compare maternal reports of play dates for 112 community subjects with 48 subjects referred for peer problems (mean age = 8.7 years). We found that clinic–referred subjects had significantly fewer hosted and invited play dates than the community subjects. The mean conflict on play dates was significantly lower for the community subjects than for the clinic-referred subjects. We obtained significant correlations between conflict on play dates and measures of problem behaviors. Our results support the position that conflict on play dates is an important area to target in social skills training programs. The scale may prove useful to clinicians and researchers by facilitating screening and assessing interventions directed towards improving play dates.     

Evaluating reading and metacognitive deficits in children and adolescents with attention deficit hyperactivity disorder

The reading achievement of children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) has scarcely been explored in research conducted in the Spanish language and when it has, the results have been contradictory. The focus of the present research is to analyze participants' reading competency and metacognitive strategies as they carry out reading comprehension tasks. The sample was comprised of 187 Argentine schoolchildren aged 9 to 13 years old. 94 constituted the control group and the clinical group consisted of 93 schoolchildren diagnosed with ADHD. The metacognitive assessment was made up of two metacognitive tests, the Reading Awareness Scale (ESCOLA; acronym in Spanish) and a Spanish adaptation of Metacognitive Awareness of Reading Strategies Inventory (MARSI), and one test of reading comprehension, the Evaluation of Reading Processes for Secondary Education Students (PROLEC-SE; acronym in Spanish). Students with ADHD had lower achievement on tests o reading comprehension compared to the control group. Nevertheless, our results suggest their difficulties did not stem from readin comprehension problems, but rather from alterations in their Executive Functions, because when subjects' reading comprehensio was equalized, students with ADHD still exhibited a lower level of Metacognition, particularly when it came to planning.     

The positive and negative framing of affirmative action: a group dominance perspective

Using a sample of 328 White, Latino, and Black Los Angeles County adults, the authors examined the tendency to employ various affirmative action "frames" (e.g., affirmative action as a "tie-breaking" device or as a quota-based policy). All three groups agreed about which frames cast affirmative action in a positive light and which cast it in a negative light. Although minorities had a tendency to frame affirmative action in terms that most people find morally acceptable, Whites had a tendency to frame affirmative action in terms most people find unacceptable. In addition, compared to minorities, Whites were less supportive of affirmative action regardless of how it was framed. LISREL modeling also was employed to test two competing models regarding predictors of the tendency to use frames that one personally finds to be relatively negative versus positive. Consistent with the expectations of social dominance theory and a motivated cognition perspective, the authors found that social dominance orientation (SDO) had significant net direct and indirect effects on one's framing of affirmative action.     

Trumping the causal influence account of causation

Here is a simple counterexample to David Lewis’s causal influence account of causation, one that is especially illuminating due to its connection to what Lewis himself writes: it is a variant of his trumping example

E‐jing: Using Information Technology to Teach about Chinese Religions

Abstract. This article discusses ways in which modern online information technologies may be used to enhance students' understanding of Chinese religions and religious texts. This discussion is predicated upon a model of linguistic communication that places significant weight on the structures and “sedimented presuppositions” of language in determining the meanings of discourse. Assignments are presented that use online technologies to give even beginning students insight into the presuppositions of Chinese religious discourse, while also allowing them to explore, kinesthetically, one of Confucianism's central practices, the reading and writing of Chinese characters. Appendices providing additional materials related to the course are available online: http://www.wabashcenter.wabash.edu/journal/article2.aspx?id=14153 .     

Free Love: A Hegelian Defense of Same‐Sex Marriage Rights

By revisiting Hegel's Philosophy of Right, I mount a Hegelian defense of same‐sex marriage rights. I first argue that Hegel's account of the Idea of freedom articulates both the necessity of popular shifts in the determinations of the institutions of right, as well as the duty to struggle to progressively actualize freedom through them. I then contend that Hegel, by grounding marriage in free consent, clears the path for expanding this ethical institution to include all monogamous couples. Lastly, I close by sketching the specifically Hegelian reasons we ought to actively struggle to expand the institution of marriage.     

Women's experiences of workplace bullying: changes in social relationships

This article reports a qualitative study, which investigated social processes in workplace bullying, based on in‐depth interviews with ten British women professionals who were targets of workplace bullying. Data were analysed using grounded theory methods. The resulting analysis showed links between disclosures of bullying, reactions of others, and some impacts on targets' psychological health. Key themes which emerged from the data included ‘being heard’ which describes how others reacted to disclosures of bullying behaviours, and the ‘ripple effect’ which describes how bullying impacted upon targets' significant others; these predominantly describe relationships with others outside the workplace. The theme of ‘withdrawal’ describes how targets and others managed relationships within the workplace, and ‘denial’ and ‘personalizing problems’ describe how others within the workplace responded to knowledge of bullying behaviours. The theme ‘maintaining self’ describes how participants responded to changed relationships and struggled to maintain a coherent sense of self during and subsequent to bullying. This research emphasizes the role of social processes and social environments, rather than individual or personality characteristics, in explaining the development of workplace bullying and its impacts on targets.
