No existing conditional semantics captures the dual role of 'if' in embedded interrogatives — 'X wonders if p' — and conditionals. This paper presses the importance and extent of this challenge, linking it to cross-linguistic patterns and other phenomena involving conditionals. Among these other phenomena are conditionals with multiple 'if'-clauses in the antecedent — 'if p and if q, then r' — and relevance conditionals — 'if you are hungry, there is food in the cupboard'. Both phenomena are shown to (...) be problematic for existing analyses. Surprisingly, the decomposition of conditionals needed to capture the link with interrogatives provides a new analysis that captures all three phenomena. The model-theoretic semantics offered here relies on a dynamic conception of meaning and compositionality, a feature discussed throughout. (shrink)

This paper aims to address the difficulties of high school students in bridging their computational understanding with their visualization skills in understanding the notion of the limits in their calculus class. This research used a pre-experimental one-group pretest-posttest design research on 62 grade 10 students enrolled in the Science, Technology, and Engineering Program (STEP) in one of the public high schools in Zamboanga del Sur, Philippines. A series of remedial sessions were given to help them understand the function values, one-sided (...) limits, limits of a function, and its discontinuities with the aid of the GeoGebra. Results revealed that there is a significant improvement in their mathematics performance before and after the remediation, t(61) = -19.99, p<.05. The real-time feedback provided by the drawing interface of GeoGebra has provided the students the insights into how objects behave in geometrical space, bridging their understanding in locating the values shown by the computational algebraic processes. Additionally, the significant difference in the achievement reveals a large effect size (Cohen’s =2.54) which could be accounted for by the remediation using interactive activities in the GeoGebra.

_An investigation into the foundations of democratic societies and the ongoing struggle over the power of concentrated wealth_ Much of our politics today, Paul Starr writes, is a struggle over entrenchment—efforts to bring about change in ways that opponents will find difficult to undo. That is why the stakes of contemporary politics are so high. In this wide‑ranging book, Starr examines how changes at the foundations of society become hard to reverse—yet sometimes are overturned. Overcoming aristocratic power was (...) the formative problem for eighteenth‑century revolutions. Overcoming slavery was the central problem for early American democracy. Controlling the power of concentrated wealth has been an ongoing struggle in the world’s capitalist democracies. The battles continue today in the troubled democracies of our time, with the rise of both oligarchy and populist nationalism and the danger that illiberal forces will entrench themselves in power. _Entrenchment_ raises fundamental questions about the origins of our institutions and urgent questions about the future.

This work explores the hypothesis that natural language is a tool for changing a language user's state of mind and, more specifically, the hypothesis that a sentence's meaning is constituted by its characteristic role in fulfilling this purpose. This view contrasts with the dominant approach to semantics due to Frege, Tarski and others' work on artificial languages: language is first and foremost a tool for representing the world. Adapted to natural language by Davidson, Lewis, Montague, et. al. this dominant approach (...) has crystalized as truth-conditional semantics: to know the meaning of a sentence is to know the conditions under which that sentence is true. Chapter 1 details the animating ideas of my alternative approach and shows that the representational function of language can be understood in terms of the more general function of changing representational mental states. Chapters 2-4 argue that the additional resources of this more general conception of meaning allow us to explain certain phenomena involving conditionals and grammatical mood that truth-conditional semantics does not. In the analysis of these specific phenomena and the articulation of the general approach on offer, it emerges that this approach combines insights and benefits from both use-theoretic and truth-theoretic work on meaning.

This paper proposes a semantics for free choice permission that explains both the non-classical behavior of modals and disjunction in sentences used to grant permission, and their classical behavior under negation. It also explains why permissions can expire when new information comes in and why free choice arises even when modals scope under disjunction. On the proposed approach, deontic modals update preference orderings, and connectives operate on these updates rather than propositions. The success of this approach stems from its capacity (...) to capture the difference between expressing the preferences that give rise to permissions and conveying propositions about those preferences.

_Repair of the Soul_ examines transformation from the perspective of Jewish mysticism and psychoanalysis, addressing the question of how one achieves self-understanding that leads not only to insight but also to meaningful change. In this beautifully written and thought-provoking book, Karen Starr draws upon a contemporary relational approach to psychoanalysis to explore the spiritual dimension of psychic change within the context of the psychoanalytic relationship. Influenced by the work of Lewis Aron, Steven Mitchell and other relational theorists, and drawing (...) upon contemporary scholarship in the field of Jewish studies, Starr brings the ideas of the Kabbalah, the ancient Jewish mystical tradition, into dialogue with modern psychoanalytic thought. _Repair of the Soul_ provides a scholarly integration of several kabbalistic and psychoanalytic themes relating to transformation, including faith, surrender, authenticity, and mutuality, as well as a unique exploration of the relationship of the individual to the universal. Starr uses the Kabbalah’s metaphors as a vivid framework with which to illuminate the experience of transformation in psychoanalytic process, and to explore the evolving view of the psychoanalytic relationship as one in which both parties - the analyst as well as the patient - are transformed.

The objective of the study was to develop a structural model that explores the relationship between Mathematics Performance and students’ self-regulated learning skills, grit, and expectancy-value towards science, technology, engineering and mathematics (STEM). The research collected survey data from 664 senior high school students from 17 STEM high schools, and conducted a covariance-based structural equation modeling (SEM) analysis. The results of the SEM analysis indicate that the Re-specified Self-Regulated Learning Skill – Expectancy-Value towards STEM – Grit – Mathematics Performance (Re-specified (...) SRL-EV-GR-MP) model is the most parsimonious fit, offering the best empirical support for the theoretical model of the study. The research findings suggest that the mathematics performance of senior high school students in STEM curriculum is attributed to their high expectancies for success and perceived values of the STEM tasks, high grit, and high self-regulated learning skills. Moreover, the research also observed evidence of mediating and moderating grit effects in the concurrent effects of expectancy-values towards STEM and self-regulated learning skills towards students’ mathematics performance.

Max Weber's distinction in "Politics as a Vocation" between the ethic of conviction and the ethic of responsibility is best understood as a distinction between mutually exclusive ethical worldviews. Interpretations that correlate the two ethics with Weber's distinction between value-rational social action and instrumental-rational social action are misleading since Weber assumes that both types of rational social action are present in both ethics. The ethic of conviction recognizes a given hierarchy of values as the context for moral endeavor. The ethic (...) of responsibility acknowledges value obligations, but assumes the absence of any given hierarchy of values and the inevitability of value conflict as the context for moral endeavor. When interpreted in the context of his multilayered understanding of value conflict, Weber's ethic of responsibility emerges as a coherent ethical perspective. (shrink)

This study developed an instrument that measures the attitude of Filipino high school students towards mathematics, with reliable predictors and factors. Using the responses of 300 high school students from Zamboanga Sibugay, the validity and reliability of the Mathematics Attitude Scale (MAS) was tested using Exploratory Factor Analysis (EFA) and reliability analyses. The EFA showed that four-factor structures of the instrument, regarding the mathematics attitude for high school students, explained 27.48% of the variance in the pattern of relationships among the (...) items. The Average Variance Extracted (AVE), Composite Reliability, and Cronbach’s Alpha coefficients were reported. They proved that the extracted constructs have obtained and satisfied convergent validity. Thirty-three items remained in the final questionnaire after deleting the twenty-seven items with factor loadings of less than 0.4 (Students’ Perceived Motivation and Support in Learning Mathematics: twelve items; Students’ Perceived Anxiety in Learning Mathematics: ten items; Students’ Perceived Self-Efficacy in Learning Mathematics: six items; and Teachers and Parents’ Influences to Students in Learning Mathematics: five items). This study has confirmed the four-factor structure of the MAS. Educators and researchers can use the MAS to better understand the attitudes of Filipino high school students towards mathematics.

After recovery, she remained a nun and has become a patient advocate and doctoral candidate in bioethics. He remained a burn surgeon and has become a bioethics teacher and author. Although they live in distant locations, (...) they maintain their friendship and frequently discuss their shared experience. Recently they met to reflect on the events, lessons, and meanings of their original encounter. (shrink)

Imperative sentences like Dance! do not seem to represent the world. Recent modal analyses challenge this idea, but its intuitive and historical appeal remain strong. This paper presents three new challenges for a non-representational analysis, showing that the obstacles facing it are even steeper than previously appreciated. I will argue that the only way for the non-representationalist to meet these three challenges is to adopt a dynamic semantics. Such a dynamic semantics is proposed here: imperatives introduce preferences between alternatives. This (...) characterization of meaning focuses on what function a sentence serves in discourse, rather than what that sentence refers to (e.g., a state of the world). By representing the meaning of imperatives, connectives and declaratives in a common dynamic format, the challenges posed for non-representationalism are met. (shrink)

A uniform theory of conditionals is one which compositionally captures the behavior of both indicative and subjunctive conditionals without positing ambiguities. This paper raises new problems for the closest thing to a uniform analysis in the literature (Stalnaker, Philosophia, 5, 269–286 (1975)) and develops a new theory which solves them. I also show that this new analysis provides an improved treatment of three phenomena (the import-export equivalence, reverse Sobel-sequences and disjunctive antecedents). While these results concern central issues in the study (...) of conditionals, broader themes in the philosophy of language and formal semantics are also engaged here. This new analysis exploits a dynamic conception of meaning where the meaning of a symbol is its potential to change an agent’s mental state (or the state of a conversation) rather than being the symbol’s content (e.g. the proposition it expresses). The analysis of conditionals is also built on the idea that the contrast between subjunctive and indicative conditionals parallels a contrast between revising and consistently extending some body of information.

A groundbreaking approach to martial arts combining Self-Image Psychology and Qigong. Martial arts teacher Phillip Starr draws on more than sixty years of experience to introduce the Mirror Image Technique--a method that recognizes the reinforcing nature of body and mind. Our self-image expresses in how we stand, move, and hold ourselves in the world; and in martial arts, the way we move reflects the way we think on the mat, in practice, and when sparring. Here, Starr pulls from (...) Self-Image Psychology and Qigong to offer readers a unique set of physical exercises that can be applied to any martial art tradition--as well as our personal lives. Like two mirrors facing each other, the physical body both reflects and changes the mind, and vice versa: our physical movements become more than just the consequence of our intentions or thoughts. As we adjust the way we move, we adjust the way we think: about ourselves, our lives, and our environments. Unlike other self-help books that consider the mind as the sole gateway to change, the Mirror Image Technique shows that cognitive transformation starts with the body. Starr takes readers through: Demonstrating key principles of Qigong with exercises like The Unbreakable Arm and The Unliftable Body Improving your stance Increasing your strike force Insights into the mindset for breaking boards (tameshiwari). Intended to enhance growth and personal development, the techniques in Martial Arts and the Mirror Image lead to a renewal of confidence and enthusiasm for one’s particular practice. (shrink)

Utterances of natural language sentences can be used to communicate not just contents, but also forces. This paper examines this topic from a cross-linguistic perspective on sentential mood. Recent work in this area focuses on conversational dynamics: the three sentence types can be associated with distinctive kinds of conversational effects called sentential forces, modeled as three kinds of updates to the discourse context. This paper has two main goals. First, it provides two arguments, on empirical and methodological grounds, for treating (...) sentential force as part of a compositional dynamic semantics, rather than a dynamic pragmatics. Second, it formulates a minimal dynamic semantic analysis that covers the data at the heart of these arguments, incorporating existing analyses of the three major moods, evidentials and conjunction. A further aim of the paper is to sharpen the distinction between sentential force and utterance force, and discuss its implications. (shrink)

Research explored methods for “shortening the food links” or developing the “local foodshed” by connecting farmers with food service buyers (for restaurants and institutions) in Colorado. Telephone interviews were used to investigate marketing and purchasing practices. Findings include that price is not a significant factor in purchasing decisions; that food buyers prioritize quality as their top purchasing criterion but are not aware that local farmers can provide higher quality, that institutions are interested in buying locally; that small farms can offer (...) comparable or higher quality produce andservice; and that farmers need to show buyers what the quality of produce and service they can provide.

A theory of the neural bases of aesthetic experience across the arts, which draws on the tools of both cognitive neuroscience and traditional humanist inquiry.

This paper attempts to provide a conceptual underpinning for codes of ethics in business and the professions. Rule-utilitarianism is a theory of ethics which I believe can successfully do this. Business persons and professionals, hopefully, will be able to develop codes of ethics in a manner consistent with a well-formulated general ethical theory. This will help enable codes of ethics to be a bridge between general ethical theory and specific ethical decisions made in business and the professions.

General Equilibrium Theory: An Introduction treats the classic Arrow-Debreu general equilibrium model in a form accessible to graduate students and advanced undergraduates in economics and mathematics. Topics covered include mathematical preliminaries, households and firms, existence of general equilibrium, Pareto efficiency of general equilibrium, the First and Second Fundamental Theorems of Welfare Economics, the core and core convergences, future markets over time and contingent commodity markets under uncertainty. Demand, supply, and excess demand appear first as functions, then optionally as correspondences. The (...) mathematics presented includes a real analysis, the Brouwer fixed point theorem, and separating and supporting hyperplane theorems. Optional chapters introduce the existence of equilibrium with set-valued supply and demand, the mathematics of upper and lower hemicontinuous correspondences, and the Kakutani fixed point theorem. The treatment emphasizes clarity and accessibility to the student through use of examples and intuition. (shrink)

A leading figure in neuroaesthetics makes the case that aesthetic experience can be meaningfully measured by the tools of neuroscience.

Many of those teaching at the intersection of medicine and the humanities are siloed within institutional spaces. This essay recounts the teaching of Sarah Manguso’s The Two Kinds of Decay to students across different academic contexts and considers what we can learn when we put classrooms in conversation with each other. This essay argues for the value of texts like Manguso’s, which explicitly hold the narrating subject and form of illness narrative up for critical examination. The authors call for more (...) collaborative teaching, which has special resonance in the health humanities, where conversations already depend on bridging disciplines and listening to the stories others can tell.

There is a big difference between saying Maya is singing, Is Maya singing? and Sing Maya! This paper examines and criticizes two attempts to rigorously explain this difference: Searle’s speech act theory and the truth-conditional reductionism advocated by Davidson and Lewis. On the speech act analysis, each utterance contains a marker which says what kind of speech act the utterance counts as performing. The truth-conditional reductionists try to reanalyze the non-declaratives (Is Maya singing? and Sing Maya!) as complex declarative forms. (...) The former analysis fails to recognize the indirect relationship between sentence (or clause) type and utterance force. The latter analysis fails to recognize the distinctive and thoroughly compositional contribution that the imperative, interrogative and declarative mood make to sentences containing them. (shrink)

The double membrane of the nuclear envelope is a formidable barrier separating the nucleus and cytoplasm of eukaryotic cells. However, movement of specific macromolecules across the nuclear envelope is critical for embryonic development, cell growth and differentiation. Transfer of molecules between the nucleus and cytoplasm occurs through the aqueous channel formed by the nuclear pore complex (NPC)Abbreviations: NPC, nuclear pore complex; GlcNac, N‐acetylglucosamine; WGA, wheat germ agglutinin. Although small molecules may simply diffuse across the NPC, transport of large proteins and (...) RNA requires specific transport signals and is energy dependent. A family of pore glycoproteins modified by O‐linked N‐acetylglucosamine moieties are essential for transport through the NPC. Recent evidence suggests that the regulation of nuclear transport may also involve the inteaction of RNA and nuclear proteins with specific binding proteins that recognize these transport signals. Are these nuclear pore glycoproteins and signal binding proteins the ‘gatekeepers’ that control access to the genetic material? Recent evidence obtained from a combination of biochemical and genetic approaches suggests – perhaps. (shrink)
