Engaging in environmental stewardship is critical for sustainability. Understanding individual differences and engagement is an important gap in present scholarship and addressing it is necessary to understand individual factors that relate to the types of activities engaged in, motivations and barriers to environmental stewardship. We surveyed 637 Canadian and American adults via Amazon Mechanical Turk, querying a range of demographic, psychological and environmental perceptions factors as well as motivations and barriers to stewardship activities. Respondents were ultimately grouped into Non-Stewards, Home-Oriented (...) Stewards and Community-Oriented Stewards. Few differences were found among these groups. However, Home-Oriented Stewards and Community-Oriented Stewards exhibited very different initial and ongoing motivations to engage in environmental stewardship. Accordingly, we identify stewardship motivations as a potential leverage point and as one of several promising avenues for future research related to enhancing engagement in environmental stewardship for the sustainability of the planet.

I appreciate very much the thoroughness with which Jocelyne St-Arnaud has analyzed the text of my paper. As she points out, the major source of difference between our approach to the authors under consideration derives from a preference for an ethical and political perspective on her side and a preference for a metaphysical perspective on mine. However, there are a few key points in interpretation that need to be addressed which go beyond this central difference in orientation.

The Logical Reasoning with Diagrams and Sentences courseware package teaches the principles of analytical reasoning and proof construction using a carefully crafted combination of textbook, desktop, and online materials. This package is sure to be an essential resource in a range of courses incorporating logical reasoning, including formal linguistics, philosophy, mathematics, and computer science. Unlike traditional formal treatments of reasoning, this package uses both graphical and sentential representations to reflect common situations in everyday reasoning where information is expressed in many (...) forms, such as finding your way to a location using a map and an address. It also teaches students how to construct and check the logical validity of a variety of proofs--of consequence and non-consequence, consistency and inconsistency, and independence--using an intuitive proof system which extends standard proof treatments with sentential, graphical, and heterogeneous inference rules, allowing students to focus on proof content rather than syntactic structure. Building upon the widely used Tarski's World and Language, Proof and Logic courseware packages, Logical Reasoning with Diagrams and Sentences contains more than three hundred exercises, most of which can be assessed by the Grade Grinder online assessment service; is supported by an extensive website through which students and instructors can access online video lectures by the authors; and allows instructors to create their own exercises and assess their students' work. Logical Reasoning with Diagrams and Sentences is an expanded revision of the Hyperproof courseware package. (shrink)

_Tarski’s World_ is an innovative and exciting method of introducing students to the language of first-order logic. Using the courseware package, students quickly master the meanings of connectives and qualifiers and soon become fluent in the symbolic language at the core of modern logic. The program allows students to build three-dimensional worlds and then describe them in first-order logic. The program, compatible with Macintosh and PC formats, also contains a unique and effective corrective tool in the form of a game, (...) which methodically leads students back through their errors if they wrongly evaluate the sentences in the constructed worlds. A brand new feature in this revised and expanded edition is student access to Grade Grinder, an innovative Internet-based grading service that provides accurate and timely feedback to students whenever they need it. Students can submit solutions for the program’s more than 100 exercises to the Grade Grinder for assessment, and the results are returned quickly to the students and optionally to the teacher as well. A web-based interface also allows instructors to manage assignments and grades for their classes. Intended as a supplement to a standard logic text, _Tarski’s World_ is an essential tool for helping students learn the language of logic. (shrink)

__Language Proof and Logic_ is available as a physical book with the software included on CD and as a downloadable package of software plus the book in PDF format. The all-electronic version is available from Openproof at ggweb.stanford.edu._ The textbook/software package covers first-order language in a method appropriate for first and second courses in logic. An on-line grading services instantly grades solutions to hundred of computer exercises. It is designed to be used by philosophy instructors teaching a logic course to (...) undergraduates in philosophy, computer science, mathematics, and linguistics. Introductory material is presented in a systematic and accessible fashion. Advanced chapters include proofs of soundness and completeness for propositional and predicate logic, as well as an accessible sketch of Godel's first incompleteness theorem. The book is appropriate for a wide range of courses, from first logic courses for undergraduates to a first graduate logic course. The software package includes four programs: Tarski's World 5.0, a new version of the popular program that teaches the basic first-order language and its semantics; Fitch, a natural deduction proof environment for giving and checking first-order proofs; Boole, a program that facilitates the construction and checking of truth tables and related notions ; Submit, a program that allows students to submit exercises done with the above programs to the Grade Grinder, the automatic grading service. Grade reports are returned to the student and, if requested, to the student's instructor, eliminating the need for tedious checking of homework. All programs are available for Windows, Macintosh and Linux systems. Instructors do not need to use the programs themselves in order to be able to take advantage of their pedagogical value. More about the software can be found at lpl.stanford.edu. The price of a new text/software package includes one Registration ID, which must be used each time work is submitted to the grading service. Once activated, the Registration ID is not transferable. (shrink)

The past twenty years have witnessed extensive collaborative research between computer scientists, logicians, linguists, philosophers, and psychologists. These interdisciplinary studies stem from the realization that researchers drawn from all fields are studying the same problem. Specifically, a common concern amongst researchers today is how logic sheds light on the nature of information. Ancient questions concerning how humans communicate, reason and decide, and modern questions about how computers should communicate, reason and decide are of prime interest to researchers in various disciplines. (...) _Words, Proofs and Diagrams_ is a collection of papers covering active research areas at the interface of logic, computer science, and linguistics. Readers of the volume will find traditional research on process logics, issues in formal semantics, and language processing. In addition, the volume also highlights a particularly new area where all three disciplines meet—the study of images and graphics as information carriers and the diagrammatic reasoning supported by them.

Abstract:Water lilies flourish in clusters and hormonally communicate together within their community. They can self-reproduce and have mobility across the water surface, being both earthed and waterborne. The capacities of water lilies are further evidence that plants require critical and cultural examination, as companion species, and that plants require an accompanying shift in human perception of their vegetal status. This paper addresses the feminist nature of the water lily and develops a connection between plant biology and the creation of models (...) for cultural practice, ethical living and a better understanding of plants.

Today a “new” field of philosophy has emerged which can be called simply “The Philosophy of Man and Woman”. Paradoxically, it is a field of study with a long and impressive history which began when the pre-Socratic philosophers first questioned their own identity in the midst of the world. Their questions fall into four broad areas:1. How is the male “opposite” to the female?2. What roles do male and female play in the generation and identity of offspring?3. Are women and (...) men wise in the same or different ways?4. Are women and men good in the same or different ways? (shrink)

Homophobia is a real and widespread problem. It results in substantial health and welfare effects. It is a legitimate issue for health and welfare reform not only because it challenges the sincerity of policy makers who talk of human rights and social justice, but because people suffer. While this paper has focused on violence as an extreme of this phenomenon, there are many other health issues that are less well documented but of considerable importance. Because homophobia is so pervasive and (...) often sanctioned by the state, it is often viewed as the status quo and its health and welfare effects overlooked. (shrink)

Collaborative undergraduate research has been shown to benefit both student participants and faculty mentors, but it is much more widely practiced in the natural sciences than in the humanities. We argue that one key reason why collaborative undergraduate research is seldom practiced in philosophy is because we philosophers have been trained to conceive of ourselves as doing research in the stove-heated room of Descartes rather than in the agora of Socrates. We discuss two types of collaborative undergraduate research projects that (...) philosophers can conduct with students in the agora, namely, projects in traditional subdisciplines of philosophy and projects in the scholarship of teaching and learning in philosophy. We argue that some projects of each type can benefit participating students and faculty mentors alike. (shrink)
