In an ω1-saturated nonstandard universe a cut is an initial segment of the hyperintegers which is closed under addition. Keisler and Leth in [KL] introduced, for each given cut U, a corresponding U-topology on the hyperintegers by letting O be U-open if for any x ∈ O there is a y greater than all the elements in U such that the interval $\lbrack x - y, x + y\rbrack \subseteq O$ . Let U be a cut in a hyperfinite time (...) line H, which is a hyperfinite initial segment of the hyperintegers. A subset B of H is called a U-Lusin set in H if B is uncountable and for any Loeb-Borel U-meager subset X of H, B ∩ X is countable. Here a Loeb-Borel set is an element of the σ-algebra generated by all internal subsets of H. In this paper we answer some questions of Keisler and Leth about the existence of U-Lusin sets by proving the following facts. (1) If $U = x/\mathbb{N} = \{y \in \mathscr{H}: \forall n \in \mathbb{N}(y < x/n)\}$ for some x ∈ H, then there exists a U-Lusin set of power κ if and only if there exists a Lusin set of the reals of power κ. (2) If U ≠ x/N but the coinitiality of U is ω, then there are no U-Lusin sets if CH fails. (3) Under ZFC there exists a nonstandard universe in which U-Lusin sets exist for every cut U with uncountable cofinality and coinitiality. (4) In any ω2-saturated nonstandard universe there are no U-Lusin sets for all cuts U except U = x/N. (shrink)

Abstract Fair resource allocation in humanitarian medicine is gaining in importance and complexity, but remains insufficiently explored. It raises specific issues regarding non-ideal fairness, global solidarity, legitimacy in non-governmental institutions and conflicts of interest. All would benefit from further exploration. We propose that some (...) headway could be made by adapting existing frameworks of procedural fairness for use in humanitarian organizations. Despite the difficulties in applying it to humanitarian medicine, it is possible to partly adapt Daniels and Sabin's ‘Accountability for reasonableness’ to this context. This would require: (1) inclusion of internally explicit decisions and rationales; (2) publicity to donors, local staff, community leaders and governments, as well as frank answers to any beneficiary—or potential beneficiary—who asked for clarification of decisions and their rationale; (3) a consistent reasoning strategy to weigh conflicting views of equity in specific situations; (4) advocacy within the organization as a mechanism for revision and appeals; and (5) internal regulation according to publicly accessible mechanisms. Organizations could generate a common corpus of allocation decisions from which to draw in future similar cases. Importantly, the complexity of these challenges should encourage, rather than hinder, broader discussion on ethical aspects of resource allocation in humanitarian medicine.

These outbreaks can be seen as a paradigm for ethical issues posed by epidemic emergencies, through the convergence of such themes as: isolation and quarantine, privacy and confidentiality and the interpretation of ethical norms across different ethnocultural settings. With an emphasis on the boundaries between public health investigations and research, this article reviews specific challenges, past practices and current normative documents relevant to the application of ethical standards in the course of outbreaks of filovirus hemorrhagic fevers. Aside from commonly identified issues of informed consent and institutional review processes, we argue for more clarity over the specification of which communities are expected to share benefits, and we advocate for the use of collective definitions of duty to care and standard of care. We propose new elaborations around existing normative instruments, and we suggest some pathways toward more comprehensive approaches to the ethics of research in outbreak situations.

Yet after summarizing an essay I wrote for the New York Times Magazine in which I argued that the avera ge Am erican family should don a te a l a r ge porti on of t h eir income to or ga n i z ati ons like UNICEF and Ox f a m , Ku per wri te s : “ But if Si n ger ’s ex h ort a ti ons make you want to act immediately in the ways he recom m en d s , you s h ould not do so.” Why not? Because the approach I advoc a te “would seriously harm the poor.” These are strong words. It is startling to be told that a substantial transfer of resources from comfortably-off American families to UNICEF or Oxfam would harm the poor. What abo ut those 3 0,0 0 0 ch i l d ren dyi n g from preventable illness and starvation? In its 2001 fund-raising material,the U.S. Committee for UNICEF says that a donation of $17 will provide immunization “to protect a child for life against the six leading ch i l d - killing and maiming diseases:measles,polio.

Let κ and λ be infinite cardinals, F a filter on κ, and G a set of functions from κ to κ. The filter F is generated by G if F consists of those subsets of κ which contain the range of some element of G. The set G is $ -closed if it is closed in the $ -topology on κ κ. (In general, the $ -topology on IA has basic open sets all Π i∈ I U i such (...) that, for all $i \in I, U_i \subseteq A$ and $|\{i \in I: U_i \neq A\}| .) The primary question considered in this paper asks "Is there a uniform ultrafilter on κ which is generated by a closed set of functions?" (Closed means $ -closed.) We also establish the independence of two related questions. One is due to Carlson: "Does there exist a regular cardinal κ and a subtree T of $^{ such that the set of branches of T generates a uniform ultrafilter on κ?"; and the other is due to Pouzet: "For all regular cardinals κ, is it true that no uniform ultrafilter on κ is analytic?" We show that if κ is a singular, strong limit cardinal, then there is a uniform ultrafilter on κ which is generated by a closed set of increasing functions. Also, from the consistency of an almost huge cardinal, we get the consistency of CH + "There is a uniform ultrafilter on ℵ 1 which is generated by a closed set of increasing functions". In contrast with the above results, we show that if κ is any cardinal, λ is a regular cardinal less than or equal to κ and P is the forcing notion for adding at least $(\kappa^{ generic subsets of λ, then in V P , no uniform ultrafilter on κ is generated by a closed set of functions.

We need to consider, and often choose, other routes to helping the poor—including ethical to u rism and fair trade in lu x u ry goods. We will not be able to invest in such feasible routes if we give away all our extra income, as Singer recommends. Sticking to donation above all, when a combination of other strategies is necessary, is highly likely to harm the poor. Si n ger doe s n’t re a lly en ga ge my argumen t .

A free ultrafilter $\mathcal{U}$ on $\omega$ is called a $T$-point if, for every countable group $G$ of permutations of $\omega$, there exists $U\in\mathcal{U}$ such that, for each $g\in G$, the set $\{x\in U:gx\ne x, gx\in U\}$ is finite. We show that each $P$-point and each $Q$-point in $\omega^*$ is a $T$-point, and, under CH, construct a $T$-point, which is neither a $P$-point, nor a $Q$-point. A question whether $T$-points exist in ZFC is open.
For a sample comprising 36,105 U.S. firm-year observations from 1985 to 2008, we find that firms located in more religious counties enjoy cheaper equity financing costs. This result is robust to a battery of sensitivity tests, including alternative assumptions and model specifications, additional controls for noise in analyst forecasts, and various approaches to addressing endogeneity. In another set of tests, we find that the equity pricing role that religion plays comes predominantly from Mainline Protestants. We also document that the effect (...) of religiosity on firms’ cost of equity capital is larger for firms (periods) lacking alternative monitoring (regulation) mechanisms as measured by lower institutional ownership (the pre-SOX era), implying that religion plays a corporate governance role. Finally, we find that the importance of religion to equity pricing is concentrated in firms that suffer lower visibility, which tend to be more sensitive to local social and economic factors. By examining the links between religiosity and valuation at the firm level, we provide strong, robust evidence supporting the perspective that religion facilitates economic development. (shrink)
One Seit Platon (mit dem Spott von Diogenes) über Kant ist die Fundamentalfrage "Was ist der Mensch?" bis heute nicht nur von der Philosophie (als regina scientiarum), sondern von der Wissenschaft überhaupt nicht beantwortet. Phänomenologisch hat der Mensch a posteriori physische (somatische), psychische(perceptio, emotio, cognitio), mentale (logische), spirituelle (conscientia, volitio, actio) "Sphären". Ontologisch in Kontext von to ti en einai (Aristoteles) sollte der Mensch a priori ein "Programm" (Information) vor der Kosmogonie haben. Der (Neo‐) Positivismus (z.B. Hume bis Carnap, Russel*; (...) * Nobel Laureate) verwirft Fragen der Metaphysik als Scheinprobleme. Damit bleibt das Menschen‐Wesen in Kontext von Postulaten, wie res cogitans (Descartes), Monaden(Leibniz), "Gott, Freiheit, Unsterblichkeit", Seligkeit und (moralischer) Vollkommenheit (Kant), absoluter Geist (Hegel) in der theologischen Dimension. Antwort könnte eine zukünftige (holistisch‐multidimensionale) philosophische theoretische und Experimentaltheologie (kontrollierbare Beobachtung) durch weitere Forschung geben, in Kontext (bzw. Existenz) von A. Physikotheologie bzw. (a) höhere (als drei) geometrische/physikalische Dimensionen (Hilbert, Riemann /Friedmann, Minkowski, Schmutzer), (b) Paralleluniversen (z.B. L. Randall), (c) Quantentheorie/‐philosophie (Planck*, u.a.), (d) Gravitations‐/Relativitätstheorie (Newton/Einstein*), (e) Vakuumenergie (Sato), etc. B. ChemoBiotheologie bzw. "psychischen" (Fechner) und "spezifischen" (Joh. Müller) Energien,"biologischem Feld" (Gurwitsch), künstlicher Biogenese (Oparin, Fox, Urey*, u.a.; 32 Fragen von John Bernal). C. Psychotheologie bzw. parapsychische Phänomene (Carrel*, Richet*/France, Rhinne/USA, Vassilev, Bechterew/Russia, etc.). D. Religionstheologie: (über‐) Bewußtsein, übersinnliche, immaterielle, supraphysikalische Phänomene (Sri Aurobindo, Dalai Lama*, Konfuzius/Laotse, Gopi Krishna, Papst Benedikt, Paramahansa Yogananda, Sri Yogendra, etc.)und ihre physiologische Begründung (Anand/Chinna, Kasamatsu/Hirai, Ornstein, Pauli*, von Weizsäcker, etc.). Damit hängt die ontologische Frage nach dem MenschenWesen mit der Lösung des Problemkomplexes "Gott Geist/Seele Mensch Natur" zusammen. (shrink)
