The use of super‐resolution imaging techniques in cell biology has yielded a wealth of information regarding cellular elements and processes that were invisible to conventional imaging. Focusing on images obtained by stimulated emission depletion (STED) microscopy, we discuss how the new high‐resolution data influence the ways in which we use and interpret images in cell biology. Super‐resolution images have lent support to some of our current hypotheses. But, more significantly, they have revealed unexpectedly complex processes that cannot be accounted for (...) by the simpler models based on diffraction‐limited imaging. The super‐resolution imaging data challenge cell biologists to change their theoretical framework, by including, for instance, interpretations that describe multiple functions, functional errors or lack of function for cellular elements. In this context, we argue that descriptive research using super‐resolution microscopy is now as necessary as hypothesis‐driven research. (shrink)

Shame and guilt are negative social emotions that are sensitive to culture, and findings from past research have suggested that shame impairs perspective-taking cognitive ability more than guilt does. However, to the best of our knowledge, there is a lack of research that has considered culture and experimentally tested the effect of shame and guilt on perspective-taking. Taking an experimental perspective, this study aimed to examine how shame and guilt states affect perspective-taking performance in two different cultures. Data from German (...) and Turkish female college students provided support for the effect of emotional state and culture on perspective-taking, but there was no interaction between them. We discussed the results and possible explanations for them in light of the literature. (shrink)

İslam düşüncesinin dini bilginin imkânı, ortaya koyulması gibi konuları içeren epistemolojik arka planı üzerindeki tartışmalar İslam Felsefesi ve teolojisinin konuları olmaya devam etmektedir. Bu bilimsel tartışma ve öğretilerin ve hayata yansıyarak gelenek halini almış biçimlerinin Müslümanların günlük hayatlarındaki tezahürleri de izlenebilmektedir. Çağdaş İslam düşüncesinde Beyani, İrfani ve Burhani olarak nitelendirilebilecek İslam bilgi anlayışları ve bunlara dayalı yaşam biçimleri gözlenebilmektedir. Hatta bunlar arasında çekişme ve çatışmalar ve bunların dini, siyasi ve eğitsel hayatlara yansımaları olabilmektedir. İlahiyat fakülteleri İslam düşünce geleneğinin teorik ve (...) pratik olarak öğrenildiği, tartışıldığı ve yaşandığı eğitim ortamlarıdır. Bu nedenle ilahiyat eğitimi alan kişilerin bu tartışmalardan haberdar olması beklenmektedir. Ve bu alt yapı ile de dini bilgiye bakışları, dini bilginin imkânı ve ona ulaşma yollarına dair çıkarımlarının ne olduğu sorusu zihinleri meşgul eden bir sorudur. Bu çalışmada, İlahiyat fakültesi öğrencilerinin dini bilgiye bakış açıları nitel araştırma yönteminin odak grup görüşmesi yoluyla tespit edilmeye çalışılmıştır. Araştırmanın sonucunda elde edilen bulgulara göre günümüz ilahiyat fakültesi öğrencilerinin tarihsel süreçte ortaya çıkan İslam bilgi yaklaşım ve tartışmalarının farklı dönemlerini yansıtan nitelikte görüşler ortaya koydukları anlaşılmaktadır. Ancak bu görüşler ağırlıklı olarak çağdaş İslam düşüncesi birikiminde yoğunlaşmaktadır. (shrink)

Background In the globalizing world, nurses often meet humans from different cultures and values. This fact has led them to make ethical decisions, which do not comply with their own moral jurisdictions at care setting. Objectives The objective of the study was to investigate the relationships between moral development levels of the nurses and their scores of nursing principled thinking and practical consideration during decision making for ethical dilemmas. Methods This was a descriptive correlational study. Nursing Dilemma Test, Moral Development (...) Scale for Professionals and socio-demographic form were used. Study was conducted with 227 nurses. Ethical considerations: An institutional authorization, an ethics approval from non-interventional ethics committee of the respective university, permission from the authors of the scales used and informed consents from the nurses were obtained in order to conduct the study. Results In this study, nurses were found to be at post-conventional level according to Kohlberg’s moral development theory. Sociodemographic and working characteristics of the nurses have not affected their scores of moral development level and their scores of nursing principled thinking, practical consideration and familiarity. Nurses take attention for moral principles during decision making although not at a desirable level, and they are relatively affected by environmental factors Conclusion Although nurses are familiar with ethical problems at scenarios including ethical dilemmas, they cannot make decisions in accordance with their moral development levels during decision making for ethical dilemmas. Nurses should be instructed and supported for ethical decision making by recognizing factors that may be effective on their decision making. (shrink)

According to truth-conditional semantics, to explain the meaning of a statement is to specify the conditions necessary and sufficient for its truth. This book develops a more radical mentalist semantics by shifting the object of semantic inquiry. Classical semantics analyzes an abstract sentence or utterance such as "Grass is green"; in attitudinal semantics the object of inquiry is a propositional attitude such as "Speaker so-and-so thinks grass is green".

Quote marks, I claim, serve to select from the multiple ostensions that are produced whenever any expression is uttered; they act to constrain pragmatic ambiguity or indeterminacy. My argument proceeds by showing that the proffered account fares better than its rivals-the Name, Description, Demonstrative, and Identity Theories. Along the way I shall need to explain and emphasize that quoting is not simply the same thing as mentioning. Quoting, but not mentioning, relies on the use of conventional devices.

Using a single spin-1 object as an example, we discuss a recent approach to quantum entanglement. [A.A. Klyachko and A.S. Shumovsky, J. Phys: Conf. Series 36, 87 (2006), E-print quant-ph/0512213]. The key idea of the approach consists in presetting of basic observables in the very definition of quantum system. Specification of basic observables defines the dynamic symmetry of the system. Entangled states of the system are then interpreted as states with maximal amount of uncertainty of all basic observables. The approach (...) gives purely physical picture of entanglement. In particular, it separates principle physical properties of entanglement from inessential. Within the model example under consideration, we show relativity of entanglement with respect to dynamic symmetry and argue existence of single-particle entanglement. A number of physical examples are considered. (shrink)

Moral philosophers widely believe that it is a part of the MEANING of 'ought' statements that they imply 'can' statements. To this thesis I offer three challenges, and then I conclude on a broader methodological note. (1) Epistemological Modal Argument: for all we know, determinism is true; determinism contradicts “ought implies can”; therefore we don’t know that 'ought' implies 'can'. (2) Metaphysical Modal Argument: determinism is conceptually possible; determinism contradicts “ought implies can”; therefore “ought implies can” is not an analytic (...) truth. (3) Semantic Argument: “You ought to X” is equivalent to “Do X!”; but “Do X!” does not entail that you can X, according to leading analyses of the imperative. (4) My two modal arguments are epistemologically significant, for they illustrate a general method for refuting a whole class of argument. (shrink)

We study combinatorial principles known as stick and club. Several variants of these principles and cardinal invariants connected to them are also considered. We introduce a new kind of side by-side product of partial orderings which we call pseudo-product. Using such products, we give several generic extensions where some of these principles hold together with ¬CH and Martin's axiom for countable p.o.-sets. An iterative version of the pseudo-product is used under an inaccessible cardinal to show the consistency of the club (...) principle for every stationary subset of limits of ω1 together with ¬CH and Martin's axiom for countable p.o.-sets.

We study L∞κ-freeness in the variety of Boolean algebras. It is shown that some of the theorems on L∞κ-free algebras which are known to hold in varieties such as groups, abelian groups etc. are also true for Boolean algebras. But we also investigate properties such as the ccc of L∞κ-free Boolean algebras which have no counterpart in the varieties above.

This note concerns the model theoretic properties of logics extending the first-order logic with monadic second-order variables equipped with the stationarity quantifier. The eight variations of the strong downward Löwenheim–Skolem Theorem down to <ℵ2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$<\aleph _2$$\end{document} for this logic with the interpretation of second-order variables as countable subsets of the structures are classified into four principles. The strongest of these four is shown to be equivalent to the conjunction of CH and the (...) Diagonal Reflection Principle for internally clubness of S. Cox. We show that a further strengthening of this SDLS and its variations follow from the Game Reflection Principle of B. König and its generalizations. (shrink)

The Demonstrative Theory holds that quoted matter is logically external to the quoting sentence, that quotation marks are (demonstratively) referential, and that quotation marks are grammatically required for autonomous mentioning. In contrast, the Identity Theory holds that quoted matter is integral to its quoting sentence, that quotation marks serve merely as disambiguating punctuation, and that mentionings need not be quotation-marked. I support the Identity Theory by pointing out fallacies in the arguments for demonstrative theories and by considering empty quotation, ordinary (...) language as found in casual use and in novels and plays, and historical and developmental facts about quotation.

A partial ordering P is said to have the weak Freese-Nation property if there is a mapping tf : P → [P]0 such that, for any a, b ε P, if a b then there exists c ε tf∩tf such that a c b. In this note, we study the WFN and some of its generalizations. Some features of the class of Boolean algebras with the WFN seem to be quite sensitive to additional axioms of set theory: e.g. under CH, (...) every ccc complete Boolean algebra has this property while, under b 2, there exists no complete Boolean algebra with the WFN.

Understanding quotation is fundamental to understanding the nature of truth and meaning. Quotation, however, is a remarkably complicated phenomenon, and a vigorous literature on the topic has been growing at an increasing rate.§1 To give you a sense of this work, §1 enlarges upon the significance of studying quotation; §2 presents a rudimentary taxonomy of quotation; and §3 critically surveys theories of how quotation works.

The utterance of any expression x ostends or makes manifest the customary referent of x, x itself, and related matter. If x appears in quotation marks then the presumed intention behind the utterance is to pick out something other than the customary referent (either instead of it or in addition to it). The consequences of these ideas, taken from my 1998 work, are here drawn out in application to a variety of quotations: metalinguistic citation, reported speech, scare-quoting, echo-quoting, loan words, (...) and titles.

A Boolean algebra B is said to be openly generated if {A: A ≤rc B, |A| = ℵ0} includes a club subset of [ B]ℵ0 . We show: (V = L). For any cardinal κ there exists an L∞κ-free Boolean algebra which is not openly generated (Proposition 4.1). (MA+(σ-closed)). Every L∞ℵa -free Boolean algebra is openly generated (Theorem 4.2). The last assertion follows from a characterization of openly generated Boolean algebras under MA+(σ-closed) (Theorem 3.1). Using this characterization we also prove (...) the independence of problem 7 in Scepin [15] (Proposition 4.3 and Theorem 4.4). (shrink)

The chapters in this volume address a variety of issues surrounding quotation, such as whether it is a pragmatic or semantic phenomenon, what varieties of quotation exist, and what speech acts are involved in quoting. Quotation poses problems for many prevailing theories of language. One fundamental principle is that for a language to be learnable, speakers must be able to derive the truth-conditions of sentences from the meanings of their parts. Another popular view is that indexical expressions like "I" display (...) a certain fixity -- that they always refer to the speaker using them. Both of these tenets appear to be violated by quotation. This volume is suitable for scholars in philosophy of language, semantics, and pragmatics, and for graduate students in philosophy and linguistics. The book will also be useful for researchers in other fields that study quotation, including psychology and computer science. (shrink)

This article shows how, in recent works of cultural analysis, the concept of ‘assemblage’ has been been derived from key sources of theory and put to work to provide a structure-like surrogate to express certain prominent values of a modernist sensibility in the discourse of description and analysis. Assemblage is a sort of anti-structural concept that permits the researcher to speak of emergence, heterogeneity, the decentred and the ephemeral in nonetheless ordered social life. There are other related concepts, like collage, (...) which have been used to give these values substance in research, but currently assemblage is enjoying a popularity perhaps because of the continuing fascination of the work of Deleuze and Guattari.

Continuing [6], [8] and [16], we study the consequences of the weak Freese-Nation property of (?(ω),⊆). Under this assumption, we prove that most of the known cardinal invariants including all of those appearing in Cichoń's diagram take the same value as in the corresponding Cohen model. Using this principle we could also strengthen two results of W. Just about cardinal sequences of superatomic Boolean algebras in a Cohen model. These results show that the weak Freese-Nation property of (?(ω),⊆) captures many (...) of the features of Cohen models and hence may be considered as a principle axiomatizing a good portion of the combinatorics available in Cohen models.

The following results are proved: In a model obtained by adding ℵ 2 Cohen reals , there is always a c.c.c. complete Boolean algebra without the weak Freese-Nation property. Modulo the consistency strength of a supercompact cardinal , the existence of a c.c.c. complete Boolean algebra without the weak Freese-Nation property is consistent with GCH. If a weak form of □ μ and cof =μ + hold for each μ >cf= ω , then the weak Freese-Nation property of 〈 P (...) ,⊆〉 is equivalent to the weak Freese-Nation property of any of C or R for uncountable κ . Modulo the consistency of ↠ , it is consistent with GCH that C does not have the weak Freese-Nation property and hence the assertion in does not hold , and also that adding ℵ ω Cohen reals destroys the weak Freese-Nation property of 〈 P , ⊆ 〉 . These results solve all of the problems except Problem 1 in S. Fuchino, L. Soukup, Fundament. Math. 154 159–176, and some other problems posed by Geschke. (shrink)

This paper discusses empty quotation (‘’ is an empty string) and lexical quotation (his praise was, quote, fulsome, unquote), it challenges the minimal theory of quotation (‘ “x” ’ quotes ‘x’) and it defends the identity theory of quotation. In the process it illuminates disciplinary differences between the science of language and the philosophy of language. First, most philosophers assume, without argument, that language includes writing, whereas linguists have reason to identify language with speech (plus sign language). Second, philosophers tend (...) to think of languages as abstract objects whereas linguists tend to think of them as natural objects. These foundational differences help to explain disagreements in grammaticality judgments and consequent disagreements in semantic theory. (shrink)

For a regular cardinal κ with κ<κ = κ and κ ≤ λ , we construct generically a subset S of {x ∈ Pκλ : x ∩ κ is a singular ordinal} such that S is stationary in a strong sense but the stationarity of S can be destroyed by a κ+-c. c. forcing ℙ* which does not add any new element of Pκλ . Actually ℙ* can be chosen so that ℙ* is κ-strategically closed. However we show that such (...) ℙ* itself cannot be κ-strategically closed or even <κ-strategically closed if κ is inaccessible.
