Academic dishonesty, including cheating and plagiarism, is on the rise in colleges, particularly among engineering students. While students decide to engage in these behaviors for many different reasons, academic integrity training can help improve their understanding of ethical decision making. The two studies outlined in this paper assess the effectiveness of an online module in increasing academic integrity among first semester engineering students. Study 1 tested the effectiveness of an academic honesty tutorial by using a between groups design with a (...) Time 1- and Time 2-test. An academic honesty quiz assessed participants’ knowledge at both time points. Study 2, which incorporated an improved version of the module and quiz, utilized a between groups design with three assessment time points. The additional Time 3-test allowed researchers to test for retention of information. Results were analyzed using ANCOVA and t tests. In Study 1, the experimental group exhibited significant improvement on the plagiarism items, but not the total score. However, at Time 2 there was no significant difference between groups after controlling for Time 1 scores. In Study 2, between- and within-group analyses suggest there was a significant improvement in total scores, but not plagiarism scores, after exposure to the tutorial. Overall, the academic integrity module impacted participants as evidenced by changes in total score and on specific plagiarism items. Although future implementation of the tutorial and quiz would benefit from modifications to reduce ceiling effects and improve assessment of knowledge, the results suggest such tutorial may be one valuable element in a systems approach to improving the academic integrity of engineering students.

Discussion of the ethics of forgoing medically provided nutrition and hydration tends to focus on adults rather than infants and children. Many appellate court decisions address the legal propriety of forgoing medically provided nutritional support of adults, but only a few have ruled on pediatric cases that pose the same issue.The cessation of nutritional support is implemented most commonly for patients in a permanent vegetative state ). An estimated 4,000 to 10,000 American children are in the permanent vegetative state, compared (...) to 10,000 to 25,000 adults. Yet the dearth of literature, case reports, and court decisions suggests that physicians and families of pediatric patients stop medically provided nutrition or seek court orders much less frequently.

Recruiting research participants based on genetic information generated about them in a prior study is a potentially powerful way to study the functional significance of human genetic variation, but it also presents ethical challenges. To inform policy development on this issue, we conducted a survey of U.S. institutional review board chairs concerning the acceptability of recontacting genetic research participants about additional research and their views on the disclosure of individual genetic results as part of recruitment. Our findings suggest there is (...) unlikely to be a “one-size-fits-all” solution, but rather several ethically acceptable approaches to genotype-driven recruitment, depending on context. Disclosures made during the consent process for the original study and the clinical validity of the results are key considerations. Researchers must be prepared to communicate and answer questions in clear lay language about what is known and not known regarding the role of genetics in their proposed area of research. (shrink)
Social networks play a significant role in learning and thus in farmers’ adoption of new agricultural technologies. This study examined the effects of social network factors on information acquisition and adoption of new seed varieties among groundnut farmers in Uganda and Kenya. The data were generated through face-to-face interviews from a random sample of 461 farmers, 232 in Uganda and 229 in Kenya. To assess these effects two alternative econometric models were used: a seemingly unrelated bivariate probit model and a (...) recursive bivariate probit model. The statistical evaluation of the SUBP shows that information acquisition and adoption decisions are interrelated while tests for the RBP do not support this latter model. Therefore, the analysis is based on the results obtained from the SUBP. These results reveal that social network factors, particularly weak ties with external support, partially influence information acquisition, but do not influence adoption. In Uganda, external support, gender, farm size, and geographic location have an impact on information acquisition. In Kenya, external support and geographic location also have an impact on information acquisition. With regard to adoption, gender, household size, and geographic location play the most important roles for Ugandan farmers, while in Kenya information from external sources, education, and farm size affect adoption choice. The study provides insight on the importance of external weak ties in groundnut farming, and a need to understand regional differences along gender lines while developing agricultural strategies. This study further illustrates the importance of farmer participation in applied technology research and the impact of social interactions among farmers and external agents. (shrink)

Brzozowski’s ‘philosophy of labour’—to which he devoted a number of writings starting in 1902—presents problems of interpretation. A conceptual approach to his conception shows it to be a sometimes uneasy mix of realist and anti-realist notions. Brzozowski appears to have thought that labour is not first of all about the things it supposedly transforms, but rather about itself. I suggest that Brzozowski can be read in the spirit of Nelson Goodman’s nominalist constructionalism (“worldmaking”). On this account, labour in Brzozowski’s (...) idiom turns out to be the constitution of forms of symbolizing sufficient unto themselves and the needs they satisfy. However, that Brzozowski was not entirely consistent in the views I impute to him—he forever sought for some ‘external’ measure of the rightness of labour/symbolizing—can be explained at least in part by his ‘humanism’, that is, his commitment to the task he assigns humankind, that of creating the one meaningful world attesting to virtually unrestricted human power.

I define ethical intuitionism as the view that it is appropriate to appeal to inferentially unsupported moral beliefs in the course of moral reasoning. I mention four common objections to this view, including the view that all such appeals to intuitionism collapse into “subjectivism”, i.e., that they make truth in ethical theory depend on what people believe. I defend intuitionism from versions of this criticism expressed by R.M. Hare and Peter Singer.
Walter Sinnott-Armstrong's recent defense of moral skepticism raises the debate to a new level, but I argue that it is unsatisfactory because of problems with its assumption of global skepticism, with its use of the Skeptical Hypothesis Argument, and with its use of the idea of contrast classes and the correlative distinction between "everyday" justification and "philosophical" justification. I draw on Chisholm's treatment of the Problem of the Criterion to show that my claim that I know that, e.g., baby-torture is (...) wrong, is no more question-begging than Sinnott-Armstrong's denial that I know this.

This anthology on creativity represents a lifetime of reading and study by the late Charles Dewey Tenney, a philosopher who had been a student of Alfred North Whitehead at Harvard. In a series of fourteen essays Tenney considers the various factors that can be identified in creativity, followed by the recorded testimony of philosophers, artists, historians, explorers, scientists and others, both theorists and practitioners. The contributors extend in time from Aristotle and Sophocles to Buckminster Fuller and May Sarton. They include (...) such diverse thinkers as Martin Luther, Karl Marx, Lewis Carroll, Julian Huxley, Albert Einstein, Abraham Lincoln, Gertrude Stein, Henry Nelson Wieman and Alfred North Whitehead. In all, more than 300 of the world's most creative individuals are included. Contents: Discovery, Invention and Creation; Roots of Discovery; Environs of Discovery; Agents of Discovery; Hinderances to Discovery; Observation and Discovery; Reason in Discovery; Reverie Discovery; Imagination in Discovery; Sensibility and Discovery; Method in Discovery; Artistry in Discovery; Diffusion; and Foresight and Discovery.

Motivated by an old construction due to J. Kalman that relates distributive lattices and centered Kleene algebras we define the functor K • relating integral residuated lattices with 0 with certain involutive residuated lattices. Our work is also based on the results obtained by Cignoli about an adjunction between Heyting and Nelson algebras, which is an enrichment of the basic adjunction between lattices and Kleene algebras. The lifting of the functor to the category of residuated lattices leads us to (...) study other adjunctions and equivalences. For example, we treat the functor C whose domain is cuRL, the category of involutive residuated lattices M whose unit is fixed by the involution and has a Boolean complement c. If we restrict to the full subcategory NRL of cuRL of those objects that have a nilpotent c, then C is an equivalence. In fact, C M is isomorphic to C e M, and C e is adjoint to, where assigns to an object A of IRL0 the product A × A 0 which is an object of NRL. (shrink)
This paper reviews the central points and presents some recent developments of the epistemic approach to paraconsistency in terms of the preservation of evidence. Two formal systems are surveyed, the basic logic of evidence (BLE) and the logic of evidence and truth (LET J ), designed to deal, respectively, with evidence and with evidence and truth. While BLE is equivalent to Nelson’s logic N4, it has been conceived for a different purpose. Adequate valuation semantics that provide decidability are given (...) for both BLE and LET J . The meanings of the connectives of BLE and LET J , from the point of view of preservation of evidence, is explained with the aid of an inferential semantics. A formalization of the notion of evidence for BLE as proposed by M. Fitting is also reviewed here. As a novel result, the paper shows that LET J is semantically characterized through the so-called Fidel structures. Some opportunities for further research are also discussed. (shrink)

Recently Samuel Richmond, generalizing Nelson Goodman, has proposed a measure of the simplicity of a theory that takes into account not only the polymorphicity of its models but also their internal homogeneity. By this measure a theory is simple if small subsets of its models exhibit only a few distinct (i.e., non-isomorphic) structures. Richmond shows that his measure, unlike that given by Goodman's theory of simplicity of predicates, orders the order relations in an intuitively satisfactory manner. In this note (...) I formalize his presentation and suggest an improvement designed to overcome certain technical difficulties. (shrink)
At the time of this writing, a widely publicized, waived-consent trial is underway. Sponsored by Northfield Laboratories, Inc. (Evanston, IL) the trial is intended to evaluate the emergency use of PolyHeme®, an oxygen-carrying resuscitative fluid that might prevent deaths from uncontrolled bleeding. The protocol allows patients in hemorrhagic shock to be randomized between PolyHeme® and saline in the field and, still without consent, randomized between PolyHeme® and blood after arrival at an emergency department. The Federal regulations that govern the waiver (...) of consent restrict its applicability to circumstances where proven, satisfactory treatments are unavailable. Blood - the standard treatment for hemorrhagic shock - is not available in ambulances but is available in hospitals. The authors argue that the in-hospital stage of the study fails to meet ethical and regulatory standards. (shrink)
