How Can Pictures be Propositions?

Wittgenstein's Picture Theory of language holds that one fact can represent another, and that propositions are pictures of states of affairs. What makes a fact into a picture of a given s tate of affairs are the correlations between picture elements and objects and the correlations between relations among picture elements and relations among objects. But a problem sometimes raised is that propositions can't be pictures, as pictures—unlike propositions—do not say anything. An interpretation (e.g. Anscombe's) holds that the above-mentioned correlations do make the picture into a proposition. But this neither handles the objection, nor is it Wittgenstein's view. Further, Wittgenstein's own account faces serious difficulties in addressing these issues, and the Anscombe-type interpretation obscures this fact.     

Examining School Attachment,Social Support,and Trauma Symptomatology Among Court-Involved,Female Students

Court-involved youth (i.e., youth in the foster care and/or juvenile justice systems), and particularly those in residential placement facilities, often present with trauma histories that can impede various areas of development and functioning. These traumatic histories can negatively impact academic performance and school success, leading to poorer outcomes later in life. In particular, female youth in these systems exhibit unique responses to traumatic experiences that further complicate healthy development. This study assesses female, court-involved students (n?=?141), exploring the relationship between school attachment and school involvement, school social support (from peers, teachers, and other staff), and trauma symptomatology among a sample of residential placement students exposed to a trauma-informed teaching intervention over the course of a school year. It was hypothesized that higher school attachment/involvement and social support would be associated with lower student trauma symptomatology. As expected, findings demonstrated that students in the sample had experienced high trauma exposure, as indicated by their high trauma symptomatology. Unexpectedly, they also had high school attachment. Furthermore, higher school attachment was associated with lower trauma symptoms among students. On the other hand, students reported lower levels of social support from classmates, which was associated with significantly higher trauma symptomatology. Implications for future research are addressed.     

Semantic games with chance moves revisited: from IF logic to partial logic

We associate the semantic game with chance moves conceived by Blinov with Blamey’s partial logic. We give some equivalent alternatives to the semantic game, some of which are with a third player, borrowing the idea of introducing the pseudo-player called Nature in game theory. We observe that IF propositional logic proposed by Sandu and Pietarinen can be equivalently translated to partial logic, which implies that imperfect information may not be necessary for IF propositional logic. We also indicate that some independent quantifiers can be regarded as dependent quantifiers of indeterminate sequence, using the interjunction connective in partial logic. We conclude our paper by indicating some further research in a more general setting.     

Argumentative Patterns in Chinese Medical Consultations

Medical argumentation in non-Western societies has attracted little attention. In line with the pragma-dialectical approach to the study of argumentation, this article identifies a prototypical argumentative pattern in Chinese medical consultations. In addition to institutional preconditions, whose relevance to the argumentative pattern has been well cited, a factor that may be equally important has remained unnoticed: the preference for certain drugs, treatments or therapeutic measurements on the basis of folk interpretations of medical phenomena in individual ethnic groups. These preferences may be seen as cultural preferences in the medical domain. In this paper, a prototypical argumentative pattern of Chinese medical consultations is provided. Two levels of the pattern are distinguished and discussed: a basic argumentative pattern as presented in the pragmatic-dialectical approach and its extensions due to cultural preferences as well as institutional constraints. Illustrated by an exemplary analysis on the basis of empirical data collected from Chinese consulting rooms, the impact of cultural preferences on physicians’ strategic maneuvering in argumentation is identified and recognized. It is argued that the existence and impact of cultural preferences require attention in medical argumentation.     

Methods Used to Document Procedural Fidelity in School-Based Intervention Research

There has been a paucity of guidance on the methodological details needed for measuring and sampling the independent variable or actual intervention occurrences in research and practice. Furthermore, the planning and support necessary to document the independent variable in both circumstances may be considerable. The current study extends prior research by reviewing the methods used to document procedural fidelity in school-based intervention research with student participants published between 2005 and 2012 in journals known for publishing school-related intervention studies. Two hundred sixty-six articles met the inclusion criteria and the majority (70 %) used fidelity data in the analysis of intervention effectiveness. By systematically examining contributions of school-based intervention researchers across targeted variables as well as qualities of interventions and settings, suggestions can be made for (a) planning measurement of fidelity across phases of the intervention, (b) sampling fidelity occurrences, (c) preventing intervention failure by providing needed supports, and (d) responding to patterns of fidelity required for intervention and outcome measurement in both research and practice.     

Two-Dimensional Awareness Logics

Awareness logic is a type of belief logic in which an agent's beliefs are restricted to those sentences that the agent is aware of. Awareness logic is a successful way to circumvent the problem of omniscience so that actual belief is modelled in a reasonable way. In this paper, we suggest a new method modelling awareness and actual belief by using two-dimensional logics. We show that the two-dimensional logics are flexible tools. Different types of concepts of awareness can be easily modelled by this method.     

Overview: For crying out loud--dangers and opportunities of communicating in the public domain

Communication often extends into the public domain, inviting "eavesdropping" and other forms of exploitation by other species. Conflict is frequently the result, although interspecific communication can be mutually beneficial even when interests conflict fundamentally, such as between predator and prey. However, the most complex communication systems are likely to involve species with mutual rather than with conflicting interests. When interests do conflict, exploitation of the communication systems of others may impose high costs on signalers and select for signals that are less exploitable. Other costs of communication in the public domain arise from "mistakes" (e.g., mating with the wrong species) and select for more species-specific signal structure. The articles in this section illustrate the complexity of interspecific communication and yield important insights into the dynamic nature of communication systems.     

An n-Player Semantic Game for an n + 1-Valued Logic

First we show that the classical two-player semantic game actually corresponds to a three-valued logic. Then we generalize this result and give an n-player semantic game for an n + 1-valued logic with n binary connectives, each associated with a player. We prove that player i has a winning strategy in game if and only if the truth value of is t _i in the model M, for 1 ≤ i ≤ n; and none of the players has a winning strategy in if and only if the truth value of is t ₀ in M.
