Pest control operations andexperimentation on sentient animals such as thebrushtail possum can cause unnecessary andavoidable suffering in the animal subjects.Minimizing animal suffering is an animalwelfare goal and can be used as a guide in thedesign and execution of animal experimentationand pest control operations.The public has little sympathy for the possum,which can cause widespread environmentaldamage, but does believe that control should beas painless as possible. Trapping and poisoningprovide only short-term solutions to the possumproblem and often involve methods that causesuffering. Intrusive experiments (...) connected withthese methods of control and published in thelast 6 years are reviewed. Many of theexperiments do not attain the welfare standardsrequired by members of the public.Possums also act as vectors for bovinetuberculosis. While this is not as important inthe minds of the public as environmentaldegradation, as long as people wish to continueraising cattle, this disease needs to becontrolled.Immunocontraception is a humane means ofcontrolling possums with wide publicacceptance. The use of vaccines for cows and/orpossums would also cause far less sufferingthan present eradication operations. Researchinto these methods does require some intrusiveexperimentation. This can be reduced if liveanimals are not used for secondary antibodyharvesting, if adequate analgesia is provided,and if potential vaccines or contraceptives aretested under conditions that would beexperienced in the field.

Background Despite national increase in pediatric ethics consultation volume over the past decade, protected time and resources for healthcare ethics consultancy work has lagged.Methods Correlation study investigating potential associations between ethics consult volume reported by recent national survey of consultants at children’s hospitals and five programmatic domains.Results 104 children’s hospitals in 45 states plus Washington DC were included. There was not a statistically significant association between pediatric ethics consult volume and hospital size, rurality of patient population, or number of consultants. (...) Academically-affiliated children’s hospitals had fewer ethics consults compared to nonacademically affiliated. Association was found between full-time equivalent (FTE) hours and number of ethics consults (p < 0.0001). Spearman rank correlation between ethics consult volume and FTE was 0.5.Conclusions While the results of this study should be interpreted with caution, investment in protected time for ethics consultancy work may translate into increased volume of pediatric ethics consults.

In an attempt to improve upon Alexander Pruss’s work (The principle of sufficient reason: A reassessment, pp. 240–248, 2006), I (Weaver, Synthese 184(3):299–317, 2012) have argued that if all purely contingent events could be caused and something like a Lewisian analysis of causation is true (per, Lewis’s, Causation as influence, reprinted in: Collins, Hall and paul. Causation and counterfactuals, 2004), then all purely contingent events have causes. I dubbed the derivation of the universality of causation the “Lewisian argument”. The (...) Lewisian argument assumed not a few controversial metaphysical theses, particularly essentialism, an incommunicable-property view of essences (per Plantinga’s, Actualism and possible worlds, reprinted in: Davidson (ed.) Essays in the metaphysics of modality, 2003), and the idea that counterfactual dependence is necessary for causation. There are, of course, substantial objections to such theses. While I think a fight against objections to the Lewisian argument can be won, I develop, in what follows, a much more intuitive argument for the universality of causation which takes as its inspiration a result from Frederic B. Fitch’s work (J Symb Logic 28(2):135–142, 1963) [with credit to who we now know was Alonzo church’s, Referee Reports on Fitch’s Definition of value, in: (Salerno (ed.), New essays on the knowability paradox, 2009)] that if all truths are such that they are knowable, then (counter-intuitively) all truths are known. The resulting Church–Fitch proof for the universality of causation is preferable to the Lewisian argument since it rests upon far weaker formal and metaphysical assumptions than those of the Lewisian argument.

Senior managers are important to the successful management of ethics in organizations. Therefore, their perceptions of organizational ethics are important. In this study, we propose that senior managers are likely to have a more positive perception of organizational ethics than lower level employees do largely because of their managerial role and their corresponding identification with the organization and need to protect the organization’s image as well as their own identity. By contrast, lower level employees are more likely to be cynical (...) about the organization’s ethics. In order to compare senior managers’ and lower level employees’ perceptions of ethics in the organization, we surveyed randomly selected senior managers and lower level employees in three firms. We found that perceptions of ethics in the organization differed predictably across levels, with senior managers’ perceptions being significantly more positive and lower level employees’ perceptions being more negative. Implications for practice and research are discussed. (shrink)

The chorion genes of Drosophila are amplified in response to developmental signals in the follicle cells of the ovary prior to their transcription. Their expression is regulated both temporally and spatially within this tissue. They thus serve as models both for the regulation of DNA replication and of developmental transcription. The regulatory elements for DNA amplification have been delineated. Their analysis reveals that amplification is mediated by several regulatory regions and initiates at defined origins within the chorion cluster. Proteins involved (...) in amplification are being identified both by mutations affecting amplification and by DNA binding studies. Regulatory elements for temporal as well as spatial control of chorion gene, expression have been characterized, and two candidate transcription factor genes have been cloned. (shrink)

Sows housed in stalls are kept insuch extreme confinement that they are unableto turn around. In some sectors of the porkindustry, sows are subjected to this degree ofconfinement for almost their entire lives(apart from the brief periods associated withmating). While individual confinement isrecognized by farmers and animal welfarecommunity organizations alike, as a valuabletool in sow husbandry (to mitigate againstaggression), what remains questionable from ananimal welfare point of view is the necessityto confine sows in such small spaces.In 2001, the Australian Journal (...) ofAgricultural Research published a reviewarticle on the science associated with the useof the sow stall, and claimed that ``noscientific evidence to support therecommendation in the Code of Practice advisingagainst housing of sows in stalls followed byhousing in crates'''' (Barnett et al., 2001, p. 21).If all the available scientific publications onthe animal welfare implications of sow stallsare consulted (many of which did not feature inthe above review), then one will indeed findscientific evidence to support recommendationsagainst the housing of sows in stalls. Becausethere is science on both sides of this policydivide, the argument to defend the use of sowstalls, therefore, is not one of science vspublic opinion, but one of ethics. (shrink)

Richard M Weaver, a thinker and writer celebrated for his unsparing diagnoses and realistic remedies for the ills of our age, is known largely through a few of his works that remain in print. This new collection of Weaver's shorter writings, assembled by Ted J Smith III, Weaver's leading biographer, presents many long-out-of-print and never-before-published works that give new range and depth to Weaver's sweeping thought. Included are eleven previously unpublished essays and speeches that were left (...) in near-final form at the time of Weaver's death in 1963. In all, there are some one hundred and twenty-six essays, speeches, book reviews, and editorials. (shrink)

One hundred years ago the expression "God is dead" was first used by Nietzsche. Now, Nietzsche was reared in a christian home, but at the university he decided there was no god.Now, this philosophy began to pervade German thought. And I believe that history is going to say that this philosophy … contributed to a religious, moral and intellectual vacuum, and into that vacuum came Nazism and the concept of the super race that produced Hitler and the second World War.Now, (...) if we in America reject the idea of god and all that that means, we're going to have a vacuum in which either a fascist type or a communist type of ideology is going to come in … that could eventually lead, in my opinion, to anarchy and chaos.The...

Although there is a significant amount of research on organizational citizenship behavior and its importance to individual and organizational outcomes, relatively little research has explored the process by which such behavior emerges and is established within an organization. Against this backdrop, we combine the perspectives offered by contextualist inquiry and actor–network theory to propose an integrative framework for investigating how organizational citizenship behavior develops in a large, heterogeneous organization. In order to illustrate the framework, we present a detailed case study (...) of recycling at a large university. Like many other organizations, the university does not have a formal organizational structure to address sustainability concerns and the initiatives are therefore mainly voluntary and emerging in nature, and outcomes are, as a consequence, highly uncertain, and fragile. We argue that contextualist inquiry in combination with actor–network theory provides new and important insights into the emergence and establishment of organizational citizenship behaviors, and that outcomes are contingent upon interactions between the context, process, and content of the behaviors in question and the related networks of human and non-human actors.

Pacifism is routinely criticized as sectarian, incoherent, and preoccupied with moral purity at the expense of responsibility. The author contends that the pacifism of John Howard Yoder is vulnerable to none of these charges and defends this claim by establishing parallels between Yoder's analysis of killing and Augustine's analysis of lying. Although, within the terms of his own argument, Augustine's rejection of all lying as unjust is consistent with his condoning of some killing as just, the author shows that given (...) a different conception of the defining characteristic of God , Augustine's theological argument against lying would become an argument against violence. The author therefore suggests that Yoder's rejection of killing is no more sectarian, incoherent, or irresponsible than Augustine's rejection of lying. (shrink)

Myra Hird and Harlan Weaver have been invited by the editors of this special issue to enter into discussion with each other – to conduct a series of interchanges – because of the careful attention their research has paid to the ways in which transness as a lived reality is ontologized in humans, non-human animals, bacteria, and viruses. With this issue’s interchanges, we would like to further the conversation on critically approaching the consequences of merging transness with animality. In (...) the following series of four essay questions, we particularly invited each of these scholars to consider moments of classificatory tension in which taxonomies of human and non-human become inflected and redirected by the categories of race, gender, sexuality, class, ability, and geopolitical location.

Philosophers who have written on modesty have largely agreed that it is a virtue, and that it therefore has an important psychological component. Mere modest behavior, it is often argued, is actually false modesty if it is generated by the wrong kind of mental state. The philosophical debate about modesty has largely focused on the question of which kind of mental state—cognitive, motivational, or evaluative—best captures the virtue of modesty. We therefore conducted a series of experiments to see which philosophical (...) account matches the folk concept of modesty. Surprisingly, we found that the folk concept is primarily behavioral. This leads us to argue that modesty may not be a virtue, but that if it is none of the extant philosophical accounts have properly explained why. (shrink)

Contemporary Roman Catholic ethics endeavors to take sin seriously by offering theologies of sin that emphasize it as a force and as a basic, personal orientation. Such efforts rightly counter the Catholic tradition's earlier reduction of sin to sins, and sins to external acts and moral culpability. But perhaps they go too far in this regard. By engaging Charles Curran, this study argues that inattention to sins undermines the theological referent of sin as a discourse that concerns more than moral (...) culpability, obscures God as the source of freedom and value, and neglects the way in which acts express and sustain sin and fashion a personal orientation. Drawing on the work of Jean Porter, the essay shows that attention to sins highlights the historicity, particularity, and provisionality of human acts because of the theological referent and analogical character of sin and sins.

Amit's efforts to provide stronger theoretical and empirical support for Hebb's cell-assembly concept is admirable, but we have serious reservations about the perspective presented in the target article. For Hebb, the cell assembly was a building block; by contrast, the framework proposed here eschews the need to fit the assembly into a broader picture of its function.

ABSTRACT: This 1974 paper builds on our 1969 paper (Corcoran-Weaver [2]). Here we present three (modal, sentential) logics which may be thought of as partial systematizations of the semantic and deductive properties of a sentence operator which expresses certain kinds of necessity. The logical truths [sc. tautologies] of these three logics coincide with one another and with those of standard formalizations of Lewis's S5. These logics, when regarded as logistic systems (cf. Corcoran [1], p. 154), are seen to be (...) equivalent; but, when regarded as consequence systems (ibid., p. 157), one diverges from the others in a fashion which suggests that two standard measures of semantic complexity may not be as closely linked as previously thought. -/- This 1974 paper uses the linear notation for natural deduction presented in [2]: each two-dimensional deduction is represented by a unique one-dimensional string of characters. Thus obviating need for two-dimensional trees, tableaux, lists, and the like—thereby facilitating electronic communication of natural deductions. The 1969 paper presents a (modal, sentential) logic which may be thought of as a partial systematization of the semantic and deductive properties of a sentence operator which expresses certain kinds of necessity. The logical truths [sc. tautologies] of this logic coincides those of standard formalizations of Lewis’s S4. Among the paper's innovations is its treatment of modal logic in the setting of natural deduction systems--as opposed to axiomatic systems. The author’s apologize for the now obsolete terminology. For example, these papers speak of “a proof of a sentence from a set of premises” where today “a deduction of a sentence from a set of premises” would be preferable. 1. Corcoran, John. 1969.

After an introduction which demonstrates the failure of the equational analogue of Beth?s definability theorem, the first two sections of this paper are devoted to an elementary exposition of a proof that a functional constant is equationally definable in an equational theory iff every model of the set of those consequences of the theory that do not contain the functional constant is uniquely extendible to a model of the theory itself.Sections three, four and five are devoted to applications and extensions (...) of this result.Topics considered here include equational definability in first order logic, an extended notion of definability in equational logic and the synonymy of equational theories.The final two sections briefly review some of the history of equational logic.

König, D. [1926. ‘Sur les correspondances multivoques des ensembles’, Fundamenta Mathematica, 8, 114–34] includes a result subsequently called König's Infinity Lemma. Konig, D. [1927. ‘Über eine Schlussweise aus dem Endlichen ins Unendliche’, Acta Litterarum ac Scientiarum, Szeged, 3, 121–30] includes a graph theoretic formulation: an infinite, locally finite and connected graph includes an infinite path. Contemporary applications of the infinity lemma in logic frequently refer to a consequence of the infinity lemma: an infinite, locally finite tree with a root has (...) a infinite branch. This tree lemma can be traced to [Beth, E. W. 1955. ‘Semantic entailment and formal derivability’, Mededelingen der Kon. Ned. Akad. v. Wet., new series 18, 13, 309–42]. It is argued that Beth independently discovered the tree lemma in the early 1950s and that it was later recognized among logicians that Beth's result was a consequence of the infinity lemma. The equivalence of these lemmas is an easy consequence of a well known result in graph theory: every connected, locally finite graph has among its partial subgraphs a spanning tree. (shrink)

In philosophy and in religious ethics, accounts of mercy are typically developed in relation to justice. The essays in this focus issue each insist on an integral connection between mercy and justice, yet each reconfigures that relationship by arguing that mercy is best understood as a normative response to others in their need. Defining mercy as our response to others’ need highlights the value of mercy as an effective public virtue, grounded in realism about the human condition and focused on (...) reparative and restorative action.

In (Weaver 2021), I showed that Boltzmann’s H-theorem does not face a significant threat from the reversibility paradox. I argue that my defense of the H-theorem against that paradox can be used yet again for the purposes of resolving the recurrence paradox without having to endorse heavy-duty statistical assumptions outside of the hypothesis of molecular chaos. As in (Weaver 2021), lessons from the history and foundations of physics reveal precisely how such resolution is achieved.

This empirical study of Fortune 1000 firms assesses the degree to which those firms have adopted various practices associated with corporate ethics programs. The study examines the following aspects of formalized corporate ethics activity: ethics-oriented policy statements; formalization of management responsibilities for ethics; free-standing ethics offices; ethics and compliance telephone reporting/advice systems; top management and departmental involvement in ethics activities; usage of ethics training and other ethics awareness activities; investigatory functions; and evaluation of ethics program activities. Results show a high (...) degree of corporate adoption of ethics policies, but wide variability in the extent to which these policies are implemented by various supporting structures and managerial activities. In effect, the vast majority of firms have committed to the low cost, possibly symbolic side of ethics management (e.g., adoption of ethics codes and policies, etc.). But firms differ substantially in their efforts to see that those policies or codes actually are put into practice. (shrink)

Self love is an inescapable problem for ethics, yet much of contemporary ethics is reluctant to offer any normative moral anthropologies. Instead, secular ethics and contemporary culture promote a norm of self-realization which is subjective and uncritical. Christian ethics also fails to address this problem directly, because it tends to investigate self love within the context of conflicts between the self's interests and those of her neighbors. Self Love and Christian Ethics argues for right self love as the solution of (...) proper self-relation that intersects with love for God and love for neighbor. Darlene Fozard Weaver explains that right self love entails a true self-understanding that is embodied in the person's concrete acts and relations. In making this argument, she calls upon ethicists to revisit ontological accounts of the self and to devote more attention to particular moral acts. (shrink)

I give two arguments for the claim that all events which occur at the actual world and are such that they could be caused, are also such that they must actually be caused. The first argument is an improvement of a similar argument advanced by Alexander Pruss, which I show to be invalid. It uses Pruss’s Brouwer Analog for counterfactual logic, and, as a consequence, implies inconsistency with Lewis’s semantics for counterfactuals. While (I suggest) this consequence may not be objectionable, (...) the argument founders on the fact that Pruss’s Brouwer Analog has a clear counterexample. I thus turn to a second, “Lewisian” argument, which requires only an affirmation of one element of Lewis’s analysis of causation and one other, fairly weak possibility claim about the nature of wholly contingent events. The final section of the paper explains how both arguments escape objections from supposed indeterminacy in quantum physics. (shrink)
