A Boolean algebra B that has a well-founded sublattice L which generates B is called a well-generated Boolean algebra. If in addition, L is generated by a complete set of representatives for B , then B is said to be canonically well-generated .Every WG Boolean algebra is superatomic. We construct two basic examples of superatomic non well-generated Boolean algebras. Their cardinal sequences are 1,0,1,1 and 0,0,20,1.Assuming MA , we show that every algebra with one of the cardinal sequences (...) , α<1, λ<20, or 0,20,1,1 is CWG.Assuming CH, or alternatively assuming MA , we determine which cardinal sequences admit only WG Boolean algebras.We find a necessary and sufficient condition for the canonical well-generatedness of algebras whose cardinal sequence has the form , α<1. We conclude that if such an algebra is CWG, then all of its quotients are CWG. We show that the above is not true for general Boolean algebras. We also conclude that if the cardinality of such an algebra is less than the cardinal defined below, then it is CWG. The cardinal is the least cardinality of an unbounded subset of {f f : ω → ω}.We investigate questions concerning embeddability, quotients and subalgebras of WG and CWG Boolean algebras, and construct various counter-examples.

Let B be a superatomic Boolean algebra (BA). The rank of B (rk(B)), is defined to be the Cantor Bendixon rank of the Stone space of B. If a ∈ B - {0}, then the rank of a in B (rk(a)), is defined to be the rank of the Boolean algebra $B b \upharpoonright a \overset{\mathrm{def}}{=} \{b \in B: b \leq a\}$ . The rank of 0 B is defined to be -1. An element a ∈ B - {0} is (...) a generalized atom $(a \in \widehat{At}(B))$ , if the last nonzero cardinal in the cardinal sequence of B $\upharpoonright$ a is 1. Let a,b $\in\widehat{At}$ (B). We denote a ∼ b, if rk(a) = rk(b) = rk(a · b). A subset H $\subseteq \widehat{At}$ (B) is a complete set of representatives (CSR) for B, if for every a $\in \widehat{At}$ (B) there is a unique h ∈ H such that h ∼ a. Any CSR for B generates B. We say that B is canonically well-generated (CWG), if it has a CSR H such that the sublattice of B generated by H is well-founded. We say that B is well-generated, if it has a well-founded sublattice L such that L generates B. THEOREM 1. Let B be a Boolean algebra with cardinal sequence $\langle\aleph_0: i . If B is CWG, then every subalgebra of B is CWG. A superatomic Boolean algebra B is essentially low (ESL), if it has a countable ideal I such that rk(B/I) ≤ 1. Theorem 1 follows from Theorem 2.9, which is the main result of this work. For an ESL BA B we define a set F B of partial functions from a certain countably infinite set to ω (Definition 2.8). Theorem 2.9 says that if B is an ESL Boolean algebra, then the following are equivalent. (1) Every subalgebra of B is CWG; and (2) F B is bounded. THEOREM 2. If an ESL Boolean algebra is not CWG, then it has a subalgebra which is not well-generated. (shrink)

In this paper, we consider a notion of nonmeasurablity with respect to Marczewski and Marczewski-like tree ideals $s_0$, $m_0$, $l_0$, $cl_0$, $h_0,$ and $ch_0$. We show that there exists a subset of the Baire space $\omega ^\omega,$ which is s-, l-, and m-nonmeasurable that forms a dominating m.e.d. family. We investigate a notion of ${\mathbb {T}}$ -Bernstein sets—sets which intersect but do not contain any body of any tree from a given family of trees ${\mathbb {T}}$. We also obtain a (...) result on ${\mathcal {I}}$ -Luzin sets, namely, we prove that if ${\mathfrak {c}}$ is a regular cardinal, then the algebraic sum of a generalized Luzin set and a generalized Sierpiński set belongs to $s_0, m_0$, $l_0,$ and $cl_0$.

The principle of the child's right to an open future was first proposed by the legal philosopher Joel Feinberg and developed further by bioethicist Dena Davis. The principle holds that children possess a unique class of rights called rights in trust—rights that they cannot yet exercise, but which they will be able to exercise when they reach maturity. Parents should not, therefore, take actions that permanently foreclose on or pre-empt the future options of their children, but leave them the greatest (...) possible scope for exercising personal life choices in adulthood. Davis particularly applies the principle to genetic counselling, arguing that parents should not take deliberate steps to create physically abnormal children, and to religion, arguing that while parents are entitled to bring their children up in accordance with their own values, they are not entitled to inflict physical or mental harm, neither by omission nor commission. In this paper, I aim to elucidate the open future principle, and consider whether it is applicable to non-therapeutic circumcision of boys, whether performed for cultural/religious or for prophylactic/health reasons. I argue that the principle is highly applicable to non-therapeutic circumcision, and conclude that non-therapeutic circumcision would be a violation of the child's right to an open future, and thus objectionable from both an ethical and a human rights perspective.

This article offers a critique of research practices typical of experimental philosophy. To that end, it presents a review of methodological issues that have proved crucial to the quality of research in the biobehavioral sciences. It discusses various shortcomings in the experimental philosophy literature related to (1) the credibility of self-report questionnaires, (2) the validity and reliability of measurement, (3) the adherence to appropriate procedures for sampling, random assignment, and handling of participants, and (4) the meticulousness of study reporting. It (...) argues that the future standing of experimental philosophy will hinge upon improvements in research methods. (shrink)

The very expertise with which psychologists wield their tools for achieving laboratory control may have had the unwelcome effect of blinding psychologists to the possibilities of discovering principles of behavior without conducting experiments. When creatively interrogated, a diverse range of large, real-world data sets provides powerful diagnostic tools for revealing principles of human judgment, perception, categorization, decision-making, language use, inference, problem solving, and representation. Examples of these data sets include patterns of website links, dictionaries, logs of group interactions, collections of (...) images and image tags, text corpora, history of financial transactions, trends in twitter tag usage and propagation, patents, consumer product sales, performance in high-stakes sporting events, dialect maps, and scientific citations. The goal of this issue is to present some exemplary case studies of mining naturally existing data sets to reveal important principles and phenomena in cognitive science, and to discuss some of the underlying issues involved with conducting traditional experiments, analyses of naturally occurring data, computational modeling, and the synthesis of all three methods.

Increasingly, US-sponsored research is carried out in developing countries, but how US Institutional Review Boards (IRBs) approach the challenges they then face is unclear.METHODS: I conducted in-depth interviews of about 2 hours each, with 46 IRB chairs, directors, administrators and members. I contacted the leadership of 60 IRBs in the United States (US) (every fourth one in the list of the top 240 institutions by National Institutes of Health (NIH) funding), and interviewed IRB leaders from 34 (55%).RESULTS: US IRBs face (...) ethical and logistical challenges in interpreting and applying principles and regulations in developing countries, given economic and health disparities, and limited contextual knowledge. These IRBs perceive wide variations in developing world IRBs/RECs' quality, resources and training; and health systems in some countries may have long-standing practices of corruption. These US IRBs often know little of local contexts, regulations and standards of care, and struggle with understandings of other cultures' differing views of autonomy, and risks and benefits of daily life. US IRBs thus face difficult decisions, including how to interpret principles, how much to pay subjects and how much sustainability to require from researchers. IRB responses and solutions include trying to maintain higher standards for developing world research, obtain cultural expertise, build IRB infrastructure abroad, communicate with foreign IRBs, and ‘negotiate’ for maximum benefits for participants and fearing ‘worst-case scenarios’.CONCLUSIONS: US and foreign IRBs confront a series of tensions and dilemmas in reviewing developing world research. These data have important implications for increased education of IRBs/RECs and researchers in the US and abroad, and for research and practice. (shrink)

Aristotle holds that there must be multiple forms of human being and those forms constitute a genos, this paper argues. Aristotle advances his claim by arguing that the strength of a polis rests on the existence of a spectrum of useful essential differences among its citizens. The paper rejects the notion that eîdos is a homonym, and argues that it signifies `form,' not `species.' Its theses are based on analysis of passages in the Ethics, Metaphysics, Politics and other works. The (...) argument of the paper is compatible with `individual' or `particular' forms. The paper also proposes a solution to the issue of `natural slavery.'. (shrink)

A standard objection to act utilitarian theories is that they are not helpful in deciding what it is morally permissible for us to do when we actually have to make a choice between alternatives. That is, such theories are worthless as decision procedures.

Even if somewhat unappealing, this is an (...) effective reply to the standard objection. (shrink)

"Practice in Christianity is the second volume in what could be called the "collected Works" of "Anti-Climacus," Kierkegaard's new pseudonym. Anti-Climacus's first volume, The Sickness Unto Death, appeared just a year earlier in 1849. The use of a pseudonym is consistent with Kierkegaard's usual practice when presenting an idealized statement of his subject, be it sexual seduction or Christian theology. Anti-Climacus argues the conceptual content of Christianity against the "leading thought of the times" and also against the ethical and social (...) import of the comforts and consolations of bourgeois culture and religion which he called "Christendom." In his own mind at least, Kierkegaards presents Christianity as it must be thought and lived if it is to be authentic. The Sickness unto Death and Practice in Christianity can be and are read quite independently, but jointly they provide the basis of Kierkegaard's devastating critique of a secularized, culturally homogenized, and tame Christianity. The authors of the studies in this present volume, Merold Westphal, Paul R. Sponheim, Murray A. Rae, Niels Jorgen Cappelorn, Sylvia Walsh, David D. Possen, Andrew J. Burgess, Christian Fink Tolstrup, Robert L. Perkins, and Wanda Warren Berry, raise a wide spectrum of issues regarding Practice in Christianity, its theology, its moral and religious psychology, and its cultural, social, and political world" --.

A deep and widespread crisis affects modern economic theory, a crisis that derives from the absence of a 'vision' - a set of widely shared political and social preconceptions - on which all economics ultimately depends. This absence, in turn, reflects the collapse of the Keynesian view that provided such a foundation from 1940 to the early 1970s, comparable to earlier visions provided by Smith, Ricardo, Mill, and Marshall. The 'unraveling' of Keynesianism has been followed by a division of discordant (...) and ineffective camps whose common denominator seems to be their shared analytical refinement and lack of practical applicability. Heilbroner and Milberg's analysis attempts both to describe this state of affairs, and to suggest the direction in which economic thinking must move if it is to regain the relevance and remedial power it now pointedly lacks.

ArgumentDuring the first half of the 1970s, climate research gained a new significance and began to be perceived within political and academic circles as being worthy of public support. Conventional explanations for this increased status include a series of climate anomalies that generated awareness and heightened concern over the potentially devastating effects of climate change. Controversial climatologist Reid Bryson was one of the first to publicly promote what he saw as a definitive link between these climate anomalies and unidirectional climate (...) change in the fall of 1973, and rising food prices in the same year gave him a platform on which to air his views to receptive senior members of the US Congress. Bryson’s testimony before a US Senate subcommittee offers a unique glimpse into how he was able to successfully resonate his agenda with that of senior politicians in a time of crisis, as well as the immediate responses of those senior US politicians upon first hearing climate change arguments. Bryson was one of the most prominent US climatologists to break a taboo against making bold climatological predictions and de-facto policy recommendations in public. As a result, although Bryson was criticized by many in the climatological community, his actions instigated the involvement of other scientists in the public arena, leading to an important elevation in US public climate discourse.

The personalistic theory of probability prescribes that a person should use personal probability assessments in decision-making and that these assessments should correspond with his judgments. Since the judgments exist solely in the assessor's mind, there is no way to prove whether or not this requirement is satisfied. De Finetti has proposed the development of methods which should oblige the assessor to make his assessments correspond with his judgments. An ideal Assessor is hypothesized and his behavior is investigated under a number (...) of such methods. The implications of these methods for the theory of personal probability are discussed. Finally, although the present interest is primarily normative, the practicability of the methods is also discussed. (shrink)

From uttering a prayer before boarding a plane, to exploring past lives through hypnosis, has superstition become pervasive in contemporary culture? Robert Park, the best-selling author of Voodoo Science, argues that it has. In Superstition, Park asks why people persist in superstitious convictions long after science has shown them to be ill-founded. He takes on supernatural beliefs from religion and the afterlife to New Age spiritualism and faith-based medical claims. He examines recent controversies and concludes that science is the (...) only way we have of understanding the world. Park sides with the forces of reason in a world of continuing and, he fears, increasing superstition. Chapter by chapter, he explains how people too easily mistake pseudoscience for science. He discusses parapsychology, homeopathy, and acupuncture; he questions the existence of souls, the foundations of intelligent design, and the power of prayer; he asks for evidence of reincarnation and astral projections; and he challenges the idea of heaven. Throughout, he demonstrates how people's blind faith, and their confidence in suspect phenomena and remedies, are manipulated for political ends. Park shows that science prevails when people stop fooling themselves. Compelling and precise, Superstition takes no hostages in its quest to provoke. In shedding light on some very sensitive--and Park would say scientifically dubious--issues, the book is sure to spark discussion and controversy. (shrink)

We can think about the use of controlled substances in the treatment of anxiety disorders in two simple but diametrically opposed ways. First, we can say that anxiety disorders are trivial and require only acts of willpower, or, if anxiety disorders do require treatment, they are better treated without the use of benzodiazepines. When BZs are used to treat anxiety, they pose grave risks of addiction to the patients to whom these medicines are prescribed; they relieve patients’ symptoms, but are (...) the equivalent of a pharmacological “roach motel,” a haven into which many unsuspecting patients enter, but from which few emerge without becoming addicted. Patients must then face terrible struggles to free themselves of dependence on BZs, and this compounds the problem for which they sought treatment. Furthermore, the large number of prescriptions for BZs are a threat to the public health because these drugs are widely abused by alcoholics and drug addicts. (shrink)

A problem of paramount importance to understanding John Dewey’s ethics is to clarify his conception of judgment and his distinction between judgments and propositions. Depending upon how one interprets him on this matter, different answers suggest themselves to some of the most basic questions underlying his ethical theory, particularly those dealing with the relationship between science and ethics, the relationship between practical judgments and descriptive statements, and the differentiae of moral and scientific judgments within the genus practical judgment. Oversimplified answers (...) are usually given to these, the stock interpretation being that he believes that ethics is reducible to science, that practical judgments are descriptive and hence that moral judgments are essentially scientific in nature. Although he undeniably says much to invite such an interpretation, it nonetheless fails to do justice to his considered view, and a probe of his account of the nature of judgments and propositions reveals that he views the whole relationship of moral to scientific judgments, hence of ethics to science, in a different light than is generally supposed. In consequence, much of his ethics needs reappraisal, particularly as having relevance to topics in the forefront of contemporary British and American ethical thought. (shrink)

The prohibition against psychologizing has been a source of confusion to many Randians. Psychologizing is the practice of incorrectly or improperly inferring motives in other people instead of rendering moral judgment. Rand thought that it could manifest in two ways: inquisitorial and excuse-making. However, Rand's concrete examples are preponderantly of the excuse-making type; her bright line between psychology and philosophy is unsuccessfully drawn; and in offering extended, strongly condemnatory analyses of the supposed motives behind psychologizing, she yields to the very (...) temptation she claims to warn against. “Psychologizing” turns out to be an anticoncept.

Whistleblowing is recognized as an important function in promoting scientific integrity, and there is a recognized need to protect whistleblowers. There is not much information available in the literature about scientific whistleblowing.

This paper is about whistleblowing from the perspective of the person blowing the whistle. Information about a few selected cases of whistleblowing is presented in an attempt (...) to augment the experiential aspect of the activity. (shrink)
