The caliber of recent discourse regarding geneticallymodified organisms (GMOs) has suffered from a lack of consensuson terminology, from the scarcity of evidence upon which toassess risk to health and to the environment, and from valuedifferences between proponents and opponents of GMOs. Towardsaddressing these issues, we present the thesis that GM should bedefined as the forcible insertion of DNA into a host genome,irrespective of the source of the DNA, and exclusive ofconventional or mutation breeding.Some defenders of the commercial use of GMOs (...) have referred to thescientific work of GMO critics as ``junk science.'''' Such a claim isfalse and misleading, given that many papers critical of both theutility and safety of GMOs have been published in peer reviewedjournals by respected scientists. In contrast, there is a dearthof peer reviewed work to substantiate the frequently heardassertions of either safety or utility in GMOs. The polarity,which now characterizes much of the public discourse on GMOs,reflects not simply scientific disagreement, but alsodisagreement in underlying value assumptions. Value differencesstrongly affect the assessment of both benefit and harm fromGMOs. (shrink)

Salmon farming is a rapidly expanding industry. In order for it to develop in an ethical manner, many ethical issues must be confronted. Among these are questions regarding the quality of life of salmon on farms. To develop reasonable answers to these questions considerable thought must be devoted to developing appropriate standards of care for salmon. If these questions are not addressed the results could be bad both for salmon and for salmon farmers.

Inquiry is an important learning strategy, even for students who cannot or do not perform actual experiments. The authors describe two activities, other than experimentation, that they used in introductory biology learning groups to emphasize inquiry abilities. They also provide recommendations for creating additional inquiry activities.

This study explores gratitude as a multidimensional and work-specific construct. Utilizing a sample of 625 employees from a variety of positions in a medium-sized school district in the United States, we developed and evaluated a new measure, namely the Work Gratitude Scale, which encompasses recognized conative, cognitive, affective, and social aspects of gratitude. A systematic, six-phased approach through structural equation modeling was used to explore and confirm the factorial structure, internal consistency, measurement invariance, concurrent, convergent, and discriminant validity of the (...) WGS. The results supported a 10-item measure with three dimensions: “grateful appraisals”, “gratitude toward others”, and “intentional attitude of gratitude”. Thereafter, first-order, second-order, and bifactor confirmatory models were estimated and compared. Work gratitude was found to be best described by a second-order construct with three underlying first-order dimensions. Measurement invariance was supported in relation to gender. Concurrent validity was supported in relation to two existing dispositional gratitude scales, namely the Gratitude Questionnaire and the Gratitude, Resentment, and Appreciation Scale. Convergent validity was supported in relation to the Core Self-Evaluations Scale and the Psychological Capital Questionnaire. Discriminant validity was supported in relation to various demographic factors such as age, gender, occupation, and tenure. The findings support the WGS as a multidimensional measure that can be used in practice to measure overall work-related gratitude and to track the effectiveness of gratitude-related workplace interventions.

Internet recruitment methods for research are rapidly evolving as technology and participant preferences do as well. This brings data security concerns, balanced with respect to persons for research participants. Internet recruitment research strategies are still important given the importance of creating private and accessible pathways for potentially marginalized populations or people experiencing stigmatized mental health conditions to participate in research. This manuscript describes the case of social media recruitment for a mental health and racism study in Fall 2022 that was (...) infiltrated by bots. We contextualize it in the context of data quality literature, with considerations for future directions including strategies for study design and management, and further research questions.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

A number of distinct definitions ofsustainable agriculture have been proposed. In this paper we criticize two such definitions, primarily for conflating sustainability with other objectives such as economic viability and ecological integrity. Finally, we propose and defend a definition which avoids our objections to the other definitions.

This book presents views of the concept of intention and its relationship to communication from three perspectives: philosphy, linguistics, and artificial intelligence. The book is a record of a workshop held in 1987.

Since publication of the 1986 Carnegie Commission report, A Nation Prepared: Teachers for the 21st Century, the professional teaching standards movement has gained noticeable momentum. The professional standards movement in teaching has been fueled by national organizations such as the National Council for Accreditation of Teacher Education, the Interstate New Teachers Assessment and Support Consortium, the National Board for Professional Teaching Standards, the National Commission on Teaching and America's Future, and by close collaboration among these four entities. Further, nearly all (...) of the fifty states are embracing the professional standards movement through formal participation in the work of one or more of these organizations. Although the professional standards movement in teaching is strong and growing stronger, its implications are not clear for instructional programs in social foundations of education, either at the teacher preparation or the advanced graduate levels. In response to the standards movement, social foundations educators have a number of options before them, three of which are to (1) largely ignore these developments, as "this too shall pass"; (2) critically interpret and resist these developments through scholarship and collective professional action, as social foundations scholars did with Competency Based Teacher Education in the 1970s; and (3) critically interpret these developments while working to strengthen the potential of the professional teaching standards movement to achieve its stated goal of providing caring and qualified teachers for every classroom in the nation. Of these three options, the last is most advisable, but it presents a considerable challenge to social foundations educators. Although the absence of social foundations skills, perspectives, and understanding should make it very difficult for teacher candidates and teachers to perform well on standards-based teaching assessments, there is no guarantee that these assessments will hold candidates accountable for social foundations learning. Implications for social foundations educators and activists are significant. (shrink)

The current paper provides readers some clarifications on the nature and goals of mass media campaigns designed to promote organ donation. These clarifications were necessitated by an earlier essay by Rady et al. (Med Health Care Philos 15:229–241, 2012) who present erroneous claims that media promotion campaigns in this health context represent propaganda that seek to misrepresent the transplantation process. Information is also provided on the nature and relative power of media campaigns in organ donation promotion.

This paper examines Nancy Chodorow's theory of feminine connection and masculine separation in The Reproduction of Mothering. First it demonstrates that, contrary to many feminists' interpretations, Chodorow's theory does not portray masculine separation as a social problem to which feminine connection is the solution. Then it shows that Chodorow's apparently intended theory is incoherent. Finally, it argues that Chodorow's claims imply another theory that is coherent and that deserves feminists' attention.

Nursing models of care show promise in addressing the needs of older adults facing serious illness through supporting inner strength. However, previous conceptual and theoretical models of inner strength are limited. This concept analysis used dimensional analysis methods to explore inner strength in people ageing with serious illness to address limitations by defining a pragmatic, data‐driven model. This study analyzed published literature of adults with serious illness that describes inner strength. Thirty articles were selected after review. The result was an (...) explanatory matrix that describes inner strength from the perspective of where have I been, where am I going? within the context of being a person who is living and dies and you have a serious illness. The conditions spotlighting by actors around me and taking stock of others and ideas lead to processes of looking in/looking out and seeing me as I’m seen. The final consequence of this process is meeting me. This updated concept analysis of inner strength improves upon previous models by providing a clinically relevant situation‐specific model of inner strength for people with serious illness. Implications for nursing scholarship and practice are described including exploration of person‐centered care, relational practice, and health communication. (shrink)

A method of developing a relational semantics and relational proof systems for many-valued logics based on finite algebras of truth values is presented. The method is applied to Rosser-Turquette logic, logics based on symmetric Heyting algebras with operators and a Post-style logic.

The use of Big Data—however the term is defined—involves a wide array of issues and stakeholders, thereby increasing numbers of complex decisions around issues including data acquisition, use, and sharing. Big Data is becoming a significant component of practice in an ever-increasing range of disciplines; however, since it is not a coherent “discipline” itself, specific codes of conduct for Big Data users and researchers do not exist. While many institutions have created, or will create, training opportunities to prepare people to (...) work in and around Big Data, insufficient time, space, and thought have been dedicated to training these people to engage with the ethical, legal, and social issues in this new domain. Since Big Data practitioners come from, and work in, diverse contexts, neither a relevant professional code of conduct nor specific formal ethics training are likely to be readily available. This normative paper describes an approach to conceptualizing ethical reasoning and integrating it into training for Big Data use and research. Our approach is based on a published framework that emphasizes ethical reasoning rather than topical knowledge. We describe the formation of professional community norms from two key disciplines that contribute to the emergent field of Big Data: computer science and statistics. Historical analogies from these professions suggest strategies for introducing trainees and orienting practitioners both to ethical reasoning and to a code of professional conduct itself. We include two semester course syllabi to strengthen our thesis that codes of conduct can be harnessed to support the development of ethical reasoning in, and a sense of professional identity among, Big Data practitioners.

_ Source: _Volume 39, Issue 3, pp 205 - 234 For many people across the world, experiences of depression include features that extend beyond the biopsychiatric model, which predominates in research on the relationship between religious and spiritual coping and depressive symptoms. How does attending to these diverse experiences of depression challenge our understanding of the dynamic between religiosity and depression? This paper presents thirteen qualitative interviews among economically marginalized mothers in the metro-Boston area. Analyzing these narratives presents a complex (...) picture of the way chronic situational stress lies beneath their experiences of depression. From this expanded view of depressive experiences, we analyze the religious coping strategies of social support and meaning making to reveal the holistic, yet often ambiguous, ways these mothers engaged religious and spiritual resources to forge hope amidst chronic stress.

Recently, we reported that melanoma risk in redheads is linked not only to pale skin, but also to the synthesis of the pigment – called pheomelanin – that gives red hair its color. We demonstrated that pheomelanin synthesis is associated with increased oxidative stress in the skin, yet we have not uncovered the chemical pathway between the molecule pheomelanin and the DNA damage that drives melanoma formation. Here, we hypothesize two possible pathways. On one hand, pheomelanin might generate reactive oxygen (...) species (ROS) that directly or indirectly cause oxidative DNA damage. On the other hand, pheomelanin synthesis might consume cellular antioxidant stores and make the cell nucleus more vulnerable to other endogenous ROS. Uncovering the mechanistic pathway between pheomelanin and oxidative DNA damage will be an important step in developing strategies to lower melanoma risk in redheads. (shrink)

Duchenne's muscular dystrophy (DMD), which affects 1/3500 live male births, involves a progressive degeneration of skeletal and cardiac muscle, leading to early death. The protein dystrophin is lacking in DMD and present, but defective, in the allelic, less severe, Becker muscular dystrophy and is also missing in the mdx mouse. Experiments on the mdx mouse have suggested two possible therapies for these myopathies. Implantation of normal muscle precursor cells (mpc) into mdx skeletal muscle leads to the conversion of dystrophin‐negative fibres (...) to ‐positive, with consequent improvement in muscle histology. Direct injectidn of dystrophin cDNA into skeletal or cardiac muscle also gives rise to dystrophin‐positive fibres. Although both appear promising, there are a number of questions to be answered and refinements to be made before either technique could be considered possible as treatments for myopathies in man.

The Classical Athenians were careful to separate the spaces of men from the spaces of gods. Yet when we look at the Athenian house, religious areas cannot be distinguished. This paper offers an investigation of how religious boundaries may be created by action and perception rather than bricks and mortar. Scholars of ancient Greek religion should not expect to see the permanence of public cult mirrored in domestic settings. One single, domestic space could host many activities; its meaning could be (...) changed by ritual behaviour. The temporary nature of domestic space allowed the residents of the Athenian house the freedom to use their domestic spaces according to their needs, thus integrating the lives of gods and men in one location.Les Athéniens de la période classique prenaient bien soin de séparer les espaces des humains de ceux des dieux. Or, lorsqu’on regarde la maison athénienne, les zones religieuses ne peuvent être distinguées. Cet article explore la manière dont les limites religieuses peuvent être crées par un geste et une perception davantage que par des briques et du ciment. Les historiens de la religion grecque ancienne ne devraient pas s’attendre à voir la permanence du culte public se refléter dans les implantations domestiques. Un seul espace domestique pouvait accueillir de nombreuses activités; sa signification pouvait être trans­formée par un comportement religieux. La nature provisoire de l’espace domestique autori­sait les habitants de la maison athénienne à user librement des espaces domestiques selon leurs besoins, mêlant dès lors la vie des dieux et celle des hommes en un seul lieu.

Seeking to unlock the secrets of consciousness, neuroscientists have been studying neural correlates of sensory awareness, such as meaningless randomly moving dots. But in the natural world of species' survival, “raw feelings” mediate conscious adaptive responses. Merker connects the brainstem with vigilance, orientating, and emotional consciousness. However, depending on the brain's phylogenetic level, raw feeling takes particular forms. (Published Online May 1 2007).
