Informed by a search of the literature about the usage of genetic testing information (GTI) by insurance companies, this paper presents a practical ethical analysis of several distinct public policy options that might be used to govern or constrain GTI usage by insurance providers. As medical research advances and the extension to the Human Genome Project (2016, https://en.wikipedia.org/wiki/human_genome_project_-_write) moves to its fullness over the next decade, such research efforts will allow the full synthesis of human DNA to be connected to (...) predictive health dispositions. As testing costs fall, there will be ever more pressure for citizens to disclose GTI. Genetic testing information is integral to future medical care because it can be used to better assess individually tailored medical therapies as well as to allow a more informed risk analysis by the insurance industry, which in some countries such as the USA underwrites a majority of citizen medical expenses. As discussed in this examination, the revelation of people’s uniquely personal GTI to insurers has enormous societal implications. The major contribution of the paper is to offer policy makers and concerned citizens a nuanced articulation of the basic options to regulate GTI, with a special consideration for ethical fairness and equity. As genetic-based medicine blossoms and pressures to reduce healthcare costs increase, there will be an ever greater impetus for countries to revisit their genetic testing policies. Organizations and policy makers striving to create GTI oversights perceived to be both “fair and effective” need to be aware of the ethical perspectives discussed in this paper. (shrink)

When physicians search the web for personal information about their patients, others have argued that this undermines patients’ trust, and the physician-patient relationship in general. We add that this practice also places other relationships at risk, and could jeopardize a physician’s career. Yet there are also reports of web searches that have unambiguously helped in the care of patients, suggesting circumstances in which a routine search of the web could be beneficial. We advance the notion that, just as nonverbal cues (...) and unsolicited information can be useful in clinical decision making, so too can online information from patients. As electronic records grow more voluminous and span more types of data, searching these resources will become a clinical skill, to be used judiciously and with care—just as evaluating the literature is, today. But to proscribe web searches of patients’ information altogether is as nonsensical as disregarding findings from physical exams—instead, what’s needed are guidelines for when to look and how to evaluate what’s uncovered, online.

Many common human traits are believed to be a composite reflection of multiple genetic and non‐genetic factors and the genetic contribution is consequently often difficult to characterise. Recent advances suggest that subtle variation in the regulation of gene expression may contribute to complex human traits. In two reports,1,2 Cheung and colleagues scale up human genetics analysis to an impressive level in a genome‐wide search for the regulators of gene expression. They perform linkage analysis on expression profiles for over 3,500 (...) class='Hi'>genes and then employ the HapMap resource3 to take positive findings through to association studies at the genome‐wide level. This work gives new insights into the complexities of gene regulation and the plausibility of genome‐wide study design. BioEssays 28: 968–972, 2006. © 2006 Wiley Periodicals, Inc. (shrink)

In this paper I present a model of rational belief change, and I show how to use it to obtain a better insight into the debate about the nature of pneumococcal transformation, genes and DNA that took place in the forties, as a result of Oswald T. Avery’s work. The model offers a particular elaboration of the concept of inference to the best explanation, along decision theoretic lines. Within this framework, I distinguish different senses in which Avery’s team can (...) be said to have proceeded with caution, thus throwing some light upon a persistent source of disagreement among researchers in the history of genetics. In addition, I explain why we are entitled to say that rival parties such as physicist Maclyn McCarty and biochemist Alfred Mirsky were epistemically rational, in spite of the fact that they reached different conclusions on the basis of the same evidence.

Behavioral genetics has as its goal the discovery of genes that play a significant causal role in complex phenotypes that are socially relevant such a parenting, aggression, psychiatric disorders, intelligence, and even race. In this article, I present the stories of the discoveries of three such important phenotypes: maternal nurturing behavior and the c-fosB gene; intelligence and phenylketonuria ; and pair-bonding and monogamy and show that the reality is considerably more complex than often portrayed. These accounts also lay bare (...) some fundamental misconceptions of this field in which genes hold a privileged place and inherently subjective phenomena are mistakenly objectified. (shrink)

The sex‐determining genes of fungi reside at one or two specialised regions of the chromosome known as the mating type (MAT) loci. The genes are sufficient to determine haploid cell identity, enable compatible mating partners to attract each other, and prepare cells for sexual reproduction after fertilisation. How conserved are these genes in different fungal groups? New work1 seeks an answer to this question by identifying the sex‐determining regions of an early diverged fungus. These regions bear remarkable (...) similarity to those described in other fungi, but the sex proteins they encode belong to only a single class of transcription factor, the high mobility group (HMG), indicating that these are likely to be ancestral to other proteins recruited for fungal sex.

The history of research on pseudoalleles, closely linked genes that have similar functions, is rich and complex. Because pseudoalleles’ proximity on the chromosome makes their distinction by the complementation tests traditionally used by geneticists difficult, and because they have similar functions, they were initially often considered as allelic forms of the same gene, hence their name. The Hox cluster is an emblematic example of a pseudoallelic gene complex. The first observations of pseudoalleles were made very early but remained puzzling (...) until a simple model explaining their formation and characteristics emerged in the middle of the 1930s. This model suggested that pseudoalleles originated by gene.. (shrink)

In recent years, sequencing technologies have enabled the identification of a wide range of non-coding RNAs (ncRNAs). Unfortunately, annotation and integration of ncRNA data has lagged behind their identification. Given the large quantity of information being obtained in this area, there emerges an urgent need to integrate what is being discovered by a broad range of relevant communities. To this end, the Non-Coding RNA Ontology (NCRO) is being developed to provide a systematically structured and precisely defined controlled vocabulary for the (...) domain of ncRNAs, thereby facilitating the discovery, curation, analysis, exchange, and reasoning of data about structures of ncRNAs, their molecular and cellular functions, and their impacts upon phenotypes. The goal of NCRO is to serve as a common resource for annotations of diverse research in a way that will significantly enhance integrative and comparative analysis of the myriad resources currently housed in disparate sources. It is our belief that the NCRO ontology can perform an important role in the comprehensive unification of ncRNA biology and, indeed, fill a critical gap in both the Open Biological and Biomedical Ontologies (OBO) Library and the National Center for Biomedical Ontology (NCBO) BioPortal. Our initial focus is on the ontological representation of small regulatory ncRNAs, which we see as the first step in providing a resource for the annotation of data about all forms of ncRNAs.

Various algorithms have been proposed for learning (partial) genetic regulatory networks through systematic measurements of differential expression in wild type versus strains in which expression of specific genes has been suppressed or enhanced, as well as for determining the most informative next experiment in a sequence. While the behavior of these algorithms has been investigated for toy examples, the full computational complexity of the problem has not received sufficient attention. We show that finding the true regulatory network requires (in (...) the worst-case) exponentially many experiments (in the number of genes). Perhaps more importantly, we provide an algorithm for determining the set of regulatory networks consistent with the observed data. We then show that this algorithm is infeasible for realistic data (specifically, nine genes and ten experiments). This infeasibility is not due to an algorithmic flaw, but rather to the fact that there are far too many networks consistent with the data (10 18 in the provided example). We conclude that gene perturbation experiments are useful in confirming regulatory network models discovered by other techniques, but not a feasible search strategy. (shrink)

Background: The search for genetic variants between racial/ethnic groups to explain differential disease susceptibility and drug response has provoked sharp criticisms, challenging the appropriateness of using race/ethnicity as a variable in genetics research, because such categories are social constructs and not biological classifications.Objectives: To gain insight into how a group of genetic scientists conceptualise and use racial/ethnic variables in their work and their strategies for managing the ethical issues and consequences of this practice.Methods: In-depth semi-structured interviews were conducted with a (...) purposive sample of 30 genetic researchers who use racial/ethnic variables in their research. Standard qualitative methods of content analysis were used.Results: Most of the genetic researchers viewed racial/ethnic variables as arbitrary and very poorly defined, and in turn as scientifically inadequate. However, most defended their use, describing them as useful proxy variables on a road to “imminent medical progress”. None had developed overt strategies for addressing these inadequacies, with many instead asserting that science will inevitably correct itself and saying that meanwhile researchers should “be careful” in the language chosen for reporting findings.Conclusions: While the legitimacy and consequences of using racial/ethnic variables in genetics research has been widely criticised, ethical oversight is left to genetic researchers themselves. Given the general vagueness and imprecision we found amongst these researchers regarding their use of these variables, they do not seem well equipped for such an undertaking. It would seem imperative that research ethicist move forward to develop specific policies and practices to assure the scientific integrity of genetic research on biological differences between population groups.

Mendelian genes have become molecular genes, with increasing puzzlement about locating them, due to increasing complexity in genomic webworks. Genome science finds modular and conserved units of inheritance, identified as homologous genes.

Genes are conserved; genes are also dynamic and creative in evolutionary speciation—most remarkably producing humans capable of wondering about (...) what genes are. (shrink)

Homology searches between DNA sequences of evolutionary distant species (phylogenetic footprinting) offer a fast detection method for regulatory sequences. Because of the small size of their genomes, tetraodontid species such as the Japanese pufferfish and green spotted pufferfish have become attractive models for comparative genomics. A disadvantage of the tetraodontid species is, however, that they cannot be bred and manipulated routinely under laboratory conditions, so these species are less attractive for developmental and genetic analysis. In contrast, an increasing arsenal of (...) transgene techniques with the developmental model species zebrafish and medaka are being used for functional analysis of cis regulatory sequences. The main disadvantage is the much larger genome. While comparison between many loci proved the suitability of phylogenetic footprinting using fish and mammalian sequences, fast rate of change in enhancer structure and gene duplication within teleosts may obscure detection of homologies. Here we discuss the contribution and potentials provided by different teleost models for the detection and functional analysis of conserved cis‐regulatory elements.

Hidden among the myriad nucleotide variants that constitute each species' gene pool are a few variants that contribute to phenotypic variation. Many of these differences that make a difference are non‐coding cis‐regulatory variants, which, unlike coding variants, can only be identified through laborious experimental analysis.

While (...) we will continue to require a diverse arsenal of experimental methods, this versatile method will speed the identification of functional genetic variation.

The joint forces of information and biological technologies are shaping us in ways that defy our traditional views about the figures of the human. Moreover, determinist tendencies favoured by scientists and the seemingly autonomy of technology development are creating a conceptual framework that privileges the search for technological answers concerning many of the human problems, keeping at the margin questions pertaining to the symbolic realm. The prevailing atmosphere nurtures the emergent composition of the natural and the artificial. It is this (...) reconfiguration that needs to be deconstructed. In the present situation we must take the problem of the public understanding of science and technology very serious and, in particular, we must develop a critical stance in order to uncover problematic presuppositions and expose to view the idea that technoscientific development is, in its nature, inevitable and desirable. Technoscientific development and its social and cultural consequences are neither facts inscribed in nature nor results strictly produced by technical reasoning. As social and cultural subjects and objects, they must be under the scrutiny of all interested and debated in the public sphere. (shrink)

Sympatric speciation illustrates how natural and sexual selection may create new species in isolation without geographic barriers. However, recent genomic reanalyses of classic examples of sympatric speciation reveal complex histories of secondary gene flow from outgroups into the radiation. In contrast, the rich theoretical literature on this process distinguishes among a diverse range of models based on simple genetic histories and different types of reproductive isolating barriers. Thus, there is a need to revisit how to connect theoretical models of sympatric (...) speciation and their predictions to empirical case studies in the face of widespread gene flow. Here, theoretical differences among different types of sympatric speciation and speciation‐with‐gene‐flow models are reviewed and summarized, and genomic analyses are proposed for distinguishing which models apply to case studies based on the timing and function of adaptive introgression. Investigating whether secondary gene flow contributed to reproductive isolation is necessary to test whether predictions of theory are ultimately borne out in nature. (shrink)

nature of modern data collection and storage techniques, and the increases in the speed and storage capacities of computers. Statistics books from 30 years ago often presented examples with fewer than 10 variables, in domains where some background knowledge was plausible. In contrast, in new domains, such as climate research where satellite data now provide daily quantities of data unthinkable a few decades ago, fMRI brain imaging, and microarray measurements of gene expression, the number of variables can range into the (...) tens of thousands, and there is often limited background knowledge to reduce the space of alternative causal hypotheses. In such domains, non-automated causal discovery techniques appear to be hopeless, while the availability of faster computers with larger memories and disc space allow for the practical implementation of computationally intensive automated search algorithms over large search spaces. Contemporary science is not your grandfather’s science, or Karl Popper’s. Causal inference without experimental controls has long seemed as if it must somehow be capable of being cast as a kind of statistical inference involving estimators with some kind of convergence and accuracy properties under some kind of assumptions. Until recently, the statistical literature said not. While parameter estimation and experimental design for the effective use of data developed throughout the 20th century, as recently as 20 years ago the methodology of causal inference without experimental controls remained relatively primitive. Besides a cessation of hostilities from the majority of the statistical and philosophical communities (which has still only partially happened), several things were needed for theories of causal estimation to appear and to flower: well defined mathematical objects to represent causal relations; well defined connections between aspects of these objects and sample data; and a way to compute those connections. A sequence of studies beginning with Dempster’s work on the factorization of probability distributions [Dempster 1972] and culminating with Kiiveri and Speed’s [Kiiveri & Speed 1982] study of linear structural equation models, provided the first, in the form of directed acyclic graphs, and the second, in the form of the “local” Markov condition..

The functions of sleep are still unknown, but are probably related to cellular and molecular aspects of neural function. To better understand the benefits that sleep may bring at the cellular level, recent studies have employed Drosophila melanogaster as a model system and shown that fruit flies share the fundamental features of mammalian sleep. As in mammals, sleep in Drosophila is characterized by increased arousal threshold and by changes in brain electrical activity. Fly sleep is homeostatically regulated independent of the (...) circadian clock, is modulated by stimulants and hypnotics, and is affected by age. Also, fly sleep is associated with changes in brain gene expression similar to those observed in mammals. While Drosophila neurobiology is sufficiently complex to permit meaningful generalizations to mammals and humans, Drosophila genetics is simple enough to allow a rapid mutagenesis screening. An ongoing mutagenesis study has screened ∼5000 mutant Drosophila lines and found that sleep amount, sleep pattern, and the homeostatic regulation of sleep are highly conserved phenotypes in flies. So far, this study has identified 10 short sleeper lines and 4 lines that show no sleep rebound after sleep deprivation. Ultimately, the characterization of these lines should help identifying crucial cellular pathways involved in the regulatory mechanisms of sleep and its functional consequences.

The combination of decreased genotyping costs and prolific social media use is fueling a personal genetic testing industry in which consumers purchase and interact with genetic risk information online. Consumers and their genetic risk profiles are protected in some respects by the 2008 federal Genetic Information Nondiscrimination Act (GINA), which forbids the discriminatory use of genetic information by employers and health insurers; however, practical and technical limitations undermine its enforceability, given the everyday practices of online social networking and its impact (...) on the workplace. In the Web 2.0 era, employers in most states can legally search about job candidates and employees online, probing social networking sites for personal information that might bear on hiring and employment decisions.

Circadian rhythm abnormalities in bipolar disorder have led to a search for genetic abnormalities in circadian "clock genes" associated with BD. However, no significant clock gene findings have emerged from genome-wide association studies. At least three factors could account for this discrepancy: complex traits are polygenic, the organization of the clock is more complex than previously recognized, and/or genetic risk for BD may be shared across multiple illnesses. To investigate these issues, we considered the clock gene network at three (...) levels: essential "core" clock genes, upstream circadian clock modulators, and downstream clock controlled genes. Using relaxed thresholds for GWAS statistical significance, we determined the rates of clock vs. control genetic associations with BD, and four additional illnesses that share clinical features and/or genetic risk with BD. Then we compared the results to a set of lithium-responsive genes. Associations with BD-spectrum illnesses and lithium-responsiveness were both enriched among core clock genes but not among upstream clock modulators. Associations with BD-spectrum illnesses and lithium-responsiveness were also enriched among pervasively rhythmic clock-controlled genes but not among genes that were less pervasively rhythmic or non-rhythmic. Our analysis reveals previously unrecognized associations between clock genes and BD-spectrum illnesses, partly reconciling previously discordant results from past GWAS and candidate gene studies.

What has been called the new mechanistic philosophy conceives of mechanisms as the main providers of biological explanation. We draw on the characterization of the p53 gene in molecular oncology, to show that explaining a biological phenomenon implies instead a dynamic interaction between the mechanistic level—rendered at the appropriate degree of ontological resolution—and far more general explanatory tools that perform a fundamental epistemic role in the provision of biological explanations. We call such tools “explanatory frameworks”. They are called frameworks to (...) stress their higher level of generality with respect to bare mechanisms; on the other hand, they are called explanatory because, as we show in this paper, their importance in explaining biological phenomena is not secondary with respect to mechanisms. We illustrate how explanatory frameworks establish selective and local criteria of causal relevance that drive the search for, characterisation and usage of biological mechanisms. Furthermore, we show that explanatory frameworks allow for changes of scientific perspective on the causal relevance of mechanisms going beyond the account provided by the new mechanistic philosophy.

The phylogenetic position of the hagfish remains enigmatic. In contrast to molecular data that suggest monophyly of the cyclostomes, several morphological features imply a more ancestral state of this animal compared with the lampreys. To resolve this question requires an understanding of the embryology of the hagfish, especially of the neural crest. The early development of the hagfish has long remained a mystery. We collected a shallow‐water‐dwelling hagfish, Eptatretus burgeri, set up an aquarium tank designed to resemble its habitat, and (...) successfully obtained several embryos. By observing the histology and expression of genes known to play fundamental roles in the neural crest, we found that the hagfish crest develops as delaminating migratory cells, as in other vertebrates. We conclude that the delaminating neural crest is a vertebrate synapomorphy that seems to have appeared from the beginning of their evolutionary history, before the splitting away of the hagfish lineage.

Research has indicated that microRNAs (miRNAs), a special class of non-coding RNAs (ncRNAs), can perform important roles in different biological and pathological processes. miRNAs’ functions are realized by regulating their respective target genes (targets). It is thus critical to identify and analyze miRNA-target interactions for a better understanding and delineation of miRNAs’ functions. However, conventional knowledge discovery and acquisition methods have many limitations. Fortunately, semantic technologies that are based on domain ontologies can render great assistance in this regard. In (...) our previous investigations, we developed a miRNA domain-specific application ontology, Ontology for MIcroRNA Target (OMIT), to provide the community with common data elements and data exchange standards in the miRNA research.

Secreted Frizzled‐related proteins (SFRPs) are modulators of the intermeshing pathways in which signals are transduced by Wnt ligands through Frizzled (Fz) membrane receptors. The Wnt networks influence biological processes ranging from developmental cell fate, cell polarity and adhesion to tumorigenesis and apoptosis. In the five or six years since their discovery, the SFRPs have emerged as dynamically expressed proteins able to bind both Wnts and Fz, with distinctive structural properties in which cysteine‐rich domains from Fz‐ and from netrin‐like proteins are (...) juxtaposed. The abundant expression of SFRP genes in the early embryo, altered expression patterns in disease states, and potential significance in the evolution of the vertebrate body plan, make these intriguing molecules relevant to investigations in diverse fields of biology and biomedical sciences.

John Maynard Smith has defended against philosophical criticism the view that developmental biology is the study of the expression of information encoded in the genes by natural selection.

Through their transcript products genes regulate the rates at which an immense variety of transcripts and subsequent proteins occur. Understanding the mechanisms that determine which genes are expressed, and when they are expressed, is one of the keys to genetic manipulation for many purposes, including the development of new treatments for disease. Viewing each gene in a genome as a distinct variable that is either on or off, or more realistically as a continuous variable, the values of some (...) of these variables influence the values of others through the regulatory proteins they express, including, of course, the possibility that the rate of expression of a gene at one time may, in various circumstances, influence the rate of expression of that same gene at a later time. If we imagine an arrow drawn from each gene expression variable at a given time to a gene variable whose expression it influences a short while after, the result is a network, technically a directed acyclic graph. For example, the DAG in Figure 1 is a representation of a system in which the expression level of gene G1 at time 1 ) causes the expression level of G2, which in turn causes the expression level of G3. The arrows in Figure 1 which do not have a variable at their tails are “error terms” which represent all of the causes of a variable other than the ones explicitly represented in the DAG. The DAG describes more than associations—it describes causal connections among gene expression rates. A shock to a cell—by mutation, heating, chemical treatment, etc. may alter the DAG describing the relations among gene expressions, for example by activating a gene that was otherwise not expressed, producing a cascade of new expression effects. Although “knockout” experiments can reveal some of the underlying causal network of gene expression levels, unless guided by information from other sources, such experiments are limited in how much of the network structure they can reveal, due to the sheer number of possible combinations of experimental manipulations of genes necessary to reveal the complete causal network. Recent developments have made it possible to compare quantitatively the expression of tens of thousands of genes in cells from different sources in a single experiment, and to trace gene expression over time in thousands of genes simultaneously. cDNA microarrays are already producing extensive data, much of it available on the web. Thus there are calls for analytic software that can be applied to microarray and other data to help infer regulatory networks. In this paper we will review current techniques that are available for searching for the causal relations between variables, describe algorithmic and data gathering obstacles to applying these techniques to gene expression levels, and describe the prospects for overcoming these obstacles.

We all live our daily lives surrounded by the products of technology that make what we do simpler, faster, and more efficient. These are benefits we often just take for granted. But at the same time, as these products disburden us of unwanted tasks that consumed much time and effort in earlier eras, many of them also leave us more disengaged from our natural and even human surroundings. It is the task of what Gene Moriarty calls focal engineering to create (...) products that will achieve a balance between disburdenment and engagement: “How much disburdenment will be appropriate while still permitting an engagement that enriches one’s life, elevates the spirit, and calls forth a good life in a convivial society?” One of his examples of a focally engineered structure is the Golden Gate Bridge, which “draws people to it, enlivens and elevates the human spirit, and resonates with the world of its congenial setting. Humans, bridge, and world are in tune.” These values of engagement, enlivenment, and resonance are key to the normative approach Moriarty brings to the profession of engineering, which traditionally has focused mainly on technical measures of evaluation such as efficiency, productivity, objectivity, and precision. These measures, while important, look at the engineered product in a local and limited sense. But “from a broader perspective, what is locally benign may present serious moral problems,” undermining “social justice, environmental sustainability, and health and safety of affected parties.” It is this broader perspective that is championed by focal engineering, the subject of Part III of the book, which Moriarty contrasts with “modern” engineering in Part I and “pre-modern” engineering in Part II.

This study is the most comprehensive account to date of modern treatments of the love commandment. Gene Outka examines the literature on agape from Nygren's Agape and Eros in 1930. Both Roman Catholic and Protestant writings are considered, including those of D'Arcy, Niebuhr, Ramsey, Tillich, and above all, Karl Barth. The first seven chapters focus on the principal treatments in the theological literature as they relate to major topics in ethical theory. The last chapter explores further the basic normative content (...) of agape and discusses some of the most characteristic problems. "The book is in my judgment the best recent work in religious ethics. Outka brings together analytic moral philosophy and theological ethics, providing a masterly survey of views and issues arising in the past forty years.... I can think of few books of interest to scholars in both philosophy and theology, but Outka's is one. Unlike some scholars who are at home in continental theology, Outka is also at home in secular analytic philosophy; he brings them together in a mutually illuminating way."--Donald Evans "Outka has mastered this vast literature on love, and has brought a critical and clarifying analysis to bear upon it. This is a most important book on a most important subject, and brings the whole discussion into a new phase."--John Macquarrie "The first thing to be said about Outka's book quite simply is that it is excellent; in fact, it is probably the very best available book about contemporary Christian ethical theory."--The Humanities Association Review.

This experimental study evaluated the influence of stated organizational concern for ethical conduct upon managerial behavior. Using an in-basket to house the manipulation, a sample of 113 MBA students with some managerial experience reacted to scenarios suggesting illegal conduct and others suggesting only unethical behavior. Stated organizational concern for ethical conduct was varied from none (control group) to several other situations which included a high treatment consisting of a Code of Ethics, an endorsement letter by the CEO and specific sanctions (...) for managerial misconduct. Only in the case of suggested illegal behavior tempered by high organizational concern were managers influenced by organizational policy to modify the morality of their actions. However, the responses to the illegal scenarios were significantly more ethical than the reactions given to the unethical (but not illegal) situations. The implications of these findings are then discussed. (shrink)

Abstract:This study examined the relationship between the individual difference variables of personal moral philosophy, locus of control, Machiavellianism, and just world beliefs and ethical judgments and behavioral intentions. A sample of 602 marketing practitioners participated in the study. Structural equation modeling was used to test hypothesized relationships. The results either fully or partially supported hypothesized direct effects for idealism, relativism, and Machiavellianism. Findings also suggested that Machiavellianism mediated the relationship between individual difference variables and ethical judgments/behavioral intentions.

This paper begins by examining several potentially unethical recent marketing practices. Since most marketing managers face ethical dilemmas during their careers, it is essential to study the moral consequences of these decisions. A typology of ways that managers might confront ethical issues is proposed. The significant organizational, personal and societal costs emanting from unethical behavior are also discussed. Both relatively simple frameworks and more comprehensive models for evaluating ethical decisions in marketing are summarized. Finally, the fact that organizational commitment to (...) fostering ethical marketing decisions can be accomplished by top management leadership, codes of ethics, ethics seminars/programs and ethical audits is examined.

Nowadays such debates appear especially volatile, both in popular culture and intellectual discourse: although there is increasing agreement that the moral and political criteria invoked in human rights documents possess cross-cultural force, many modern and postmodern developments erode confidence in moral appeals that go beyond a local consensus or apply outside a particular community. Often the point of departure for discussion is the Enlightenment paradigm of (...) a common morality, in which it is assumed that certain unchanging beliefs inhere in the structure of human reason. Whereas some thinkers continue to defend this paradigm, others modify it in diverse ways without abandoning entirely the attempt to address a universal audience, and still others jettison virtually all of its distinguishing features. Exhibiting a range of positions Western participants take in these debates, this volume seeks to advance the substance of the debates themselves without prejudging the outcome. Rival assessments of the Enlightenment paradigm are offered from various philosophical and theological points of view. In addition to the editors, the contributors include Robert Merrihew Adams, Annette C. Baier, Alan Donagan, Margaret A. Farley, Alan Gewirth, David Little, Richard Rorty, Jeffrey Stout, and Lee H. Yearley. (shrink)

This paper answers the questions ‘what is the Merchant of Venice?’ and ‘how may it accomplish its purpose?’ I argue that the usual treatments of this play are inadequate and show how the play is a comedy through which the passions appropriate for the good human being are engendered. What is raised and ridiculed are our own temptations to lesser joys and less sweet uses mimetically roused in us by the action and characters of the play. What is whetted but (...) left unsatisfied is our higher love for justice. Thus the play provides a catharsis (purification) of desire and sympathy. (shrink)

A societal goal to which more and more people in the United States appear to be committed--at least officially--is the assurance of comprehensive health services for every person irrespective of income or geographic location. This paper offers one possible moral justification of the goal. It does so by attempting to apply various standard conceptions of social justice to considerations about health care and to reflect about the reasons why some of the conceptions seem more relevant than others. Several institutional implications (...) are also identified. (shrink)
