Early versions of satellite and radiosonde datasets suggested that the tropical surface had warmed more than the troposphere, while climate models consistently showed tropospheric amplification of surface warming in response to human-caused increases in greenhouse gases. We revisit such comparisons here using new observational estimates of surface and tropospheric temperature changes. We find that there is no longer a serious discrepancy between modeled and observed trends in the tropics. Our results contradict a recent claim that all simulated temperature trends in (...) the tropical troposphere are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.This emerging reconciliation of models and observations has two primary explanations. First, because of changes in the treatment of buoy and satellite information, new surface temperature datasets yield slightly reduced tropical warming relative to earlier versions. Second, recently developed satellite and radiosonde datasets now show larger warming of the tropical lower troposphere. In the case of a new satellite dataset from remote sensing systems, enhancedRSS warming is due to an improved procedure of adjusting for inter-satellite biases. When the RSS-derived tropospheric temperature trend is compared with four different observed estimates of surface temperature change, the surface warming is invariably amplified in the tropical troposphere, consistent with model results. Even if we use data from a second satellite dataset with smaller tropospheric warming than in remote sensing systems RSS, observed tropical lapse rates are not significantly different from those in all model simulations.Our results contradict a recent claim that all simulated temperature trends in the tropical troposphere and in tropical lapse rates are inconsistent with observations. This claim was based on the use of older radiosonde and satellite datasets and on two methodological errors: the neglect of observational trend uncertainties introduced by interannual climate variability and application of an inappropriate statistical “consistency test”.

Summary A study of the metallurgy and manufacturing techniques of a group of eight astrolabes (seven from Lahore, one attributed to India) using non-destructive methods has produced the earliest evidence for systematic use of high-zinc (α?+??) brass. To produce this alloy, the brass industry supplying the Lahore instrument makers must have co-melted metallic copper and zinc. This brass-making technology was previously believed to have been developed on an industrial scale in the nineteenth century in Europe. This work hypothesizes that this (...) technology was used in Lahore on an industrial scale as early as ad 1601. In addition, this work hypothesizes that the α?+?? brass alloy was used specifically for its ease in manufacturing the thin sheet brass required for astrolabe-component manufacture. (shrink)

Sutton ( 2010 ) claims that on our analysis (2007), the problem in the two-envelope paradox is an error in counterfactual reasoning. In fact, we distinguish two formulations of the paradox, only one of which, on our account, involves an error in conditional reasoning. According to Sutton, it is conditional probabilities rather than subjunctive conditionals that are essential to the problem. We argue, however, that his strategy for assigning utilities on the basis of conditional probabilities leads to absurdity. In addition, (...) we show that a crucial presupposition of Sutton’s argument — namely, that one can know that envelope A contains n simply on the basis of a stipulation — is mistaken. (shrink)

Merleau-Ponty had projected a work of considerable dimensions, according to Lefort, which was to have borne the title now given to this posthumous volume. Though the chapters he had actually written out and the notes de travail selected by Lefort for this edition seem to be only introductory parts and suggestions of the larger work, they are already considerable in richness, depth and difficulty. Here we find Merleau-Ponty returning to the problems of his earlier works, showing why the problems posed (...) in the Phenomenology of Perception were "insoluble"; examining in ever greater depth the thought of Descartes, Leibniz, Kant, Hegel, Husserl, Heidegger and Sartre; uncovering the naiveté of scientific thinking and the false sophistication of reflective, dialectical and intuitionistic philosophies. He has moved well beyond phenomenology in the strict sense, toward his own interrogation ontologique and a theory of logic. Lefort has done an extraordinary and exemplary job of organizing, editing and annotating the manuscripts. —A. B. D. and C. D. (shrink)

In addition to facing the known competitors in the formal economy, entrepreneurs must also be concerned with rivalry emanating from the informal economy. The informal economy is characterized by actions outside the normal scope of commerce, such as unsanctioned payments and gift-giving, as means of influencing competition. Scholars and policy makers alike have an interest in mitigating the impacts of such informal activity in that it might present an obstacle for legitimate commerce. Received theory suggests that country institutions can enable (...) and constrain productive activity, and, in doing so, influence competitive obstacles in a country. Leveraging 13,670 responses from entrepreneurs distributed across 59 countries, we provide evidence that two particular types of enabling institutions, countries’ property rights regulations and cooperative actions, are useful for lowering the obstacles presented by informal activity. We also find evidence that two constraining institutions, economic and financial regulations lead to more obstacles presented by informal activity. We describe implications for entrepreneurs, policy makers, and future researchers stemming from these findings. (shrink)

Science naively presupposes the intelligibility of the universe, necessary laws, and a universal truth. The author reflects on these presuppositions to arrive at a demonstration of God's existence. In a vigorous and exclamatory style, he condemns the alternative views of idealism, phenomenology, and philosophies of science which cannot rationally justify their faith in a universal truth. The only rational basis for these presuppositions is a theistic God--the "Vérité mesurante" and "Pensée fondatrice" of scientific reason.--A. B. D.

Aristotle's rejection of the Platonic ideas robbed him of Plato's unity of Being and Value as well. By an extensive, clear interpretation and analysis of the whole Aristotelian corpus, Oates shows that Aristotle lacks a coherent theory of value. While considerations of value unavoidably occur in the Metaphysics, just as ontological ones do in the Ethics, nowhere in Aristotle is there a unification of axiology and ontology. For this reason, Oates argues, the Nicomachean Ethics fails to be a theory of (...) moral good. The book is a temperate, perhaps non-controversial critique of Aristotle, and its polished, easy style makes it a pleasure to read.—A. B. D. (shrink)

A scholarly, clearly written interpretation of the Oresteia, interweaving the aesthetic, moral, political and cosmic elements in the drama. The author gives a valuable assessment of Aeschylus' reaction to the then current ideas of Plato and Aristotle. In an excellent chapter on the meanings of catharsis, he shows how Aeschylus interpreted Aristotle's theory of tragedy.--A. B. D.

A bi-lingual edition of poems and a "free philosophical treatise" by a poet-logician who is now imprisoned somewhere in Russia. In this choppy and compressed treatise, written hours before he was arrested, the writer discusses some pseudo-problems of philosophy, argues against the principle of excluded middle, and states the real problem of philosophy as being the relationship between the subconscious and consciousness.--A. B. D.

This second, more cohesive volume of Schutz's papers goes beyond the critical and inconclusive work of Volume I, to advance, not quite a theory, but certain postulates for the interpretation of social phenomena. Schutz contends that the social scientist, normally an impartial observer, must also assume the standpoint of the subject: he must ask what is the meaning and rationality of social action for the actor himself. From such a bi-polar perspective Schutz describes the situations of "The Stranger," "The Homecomer," (...) and "The Well-Informed Citizen." In the longest paper he analyzes the meaning of equality both for those who are and for those who are not equal. These papers are perceptive—the best in the volume.—A. B. D. (shrink)

In the French unclassifiable genre, Brun explores biological evolution, poetry, philosophy, mythology, dance movements and palm-reading to unearth the significance and function of the human hand. Man does not have a hand; part of his being is being-a-hand. He is differentiated from animals not only because he is a tool-user, but because he can make tools to make other tools. Brun shows that the sense of touch overcomes the separation between man and the world in a second section dealing with (...) the erotic, cognitive and existential meanings of le toucher. A difficult, sometimes insightful study but mainly overstated.—A. B. D. (shrink)

Theories of immanence and botanical analogy dominated the work of the eighteenth-century naturalists. They believed, with little factual support, that electricity was the immanent principle of the universe and that plants and animals had truly analogical functions. When a science of biology finally came into being in the nineteenth century, the romantic poets decried the positivistic approach to nature; but it was often overlooked that their poetry voiced anew the concepts of the eighteenth-century speculation. The super-abundance of quotations makes for (...) laborious reading, although the author deftly threads his narrative through them.—A. B. D. (shrink)

Edith Stein was Husserl's student and private secretary. This study of empathy was originally her doctoral dissertation. After a reduction to pure consciousness, she describes the essence of empathy as a kind of perception sui generis, both like and unlike other acts of consciousness. Different theories of experiencing the other are briefly evaluated. The second part of the book is devoted to the role of empathy in the constitution of the psycho-physical individual and, ultimately, of the person. Written in short, (...) numbered paragraphs, the analysis tends to be jerky and without direction. But there is a sustained description of the living body, antedating Merleau-Ponty's corps vécu by thirty years. The translation seems too literal, and typographical errors abound.—A. B. D. (shrink)
