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)

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)

In my first study of the borrowings from Athenian sacred treasure to finance the Archidamian War I assumed, in common with others, certain irregularities in the stoichedon order of IG. i. 324. The text has subsequently been amplified and improved by Tod, notably with the addition of one amount of interest due to Athena and of the total amounts of principal credited to the Other Gods and to all the gods . This further expansion, however, has introduced additional irregularities, the (...) restoration [τάδε τος λλοις θεος έλοσι τόκο ]ν νδεκα τεα[ιν:…] being too long by one letter in line 120 and the restoration [τάδε πασι τος θεος έλοσι τόκο ν] νδεκα τεσ[ιν:…] being likewise too long in line 123.

This first article is intended as a brief introduction to the general philosophical assumptions of Newton: namely, his mathematicism, empiricism, positivism, reductionism, and dualism. These five "isms" provide an important background to the main articles that are also briefly described.

Newton's conception of time has had a profound influence upon science, particularly psychology. Five characteristics of explanation have devolved from Newton's temporal framework: objectivity, continuity, linearity, universality, and reductivity. These characteristics are outlined in the present essay and shown to be central to psychological theories and methods. Indeed, Newton's temporal framework is so central that it often goes unexamined in psychology. Examination is important, however, because recent critics of Newton's framework - including both scientists and philosophers - have questioned its (...) validity and usefulness. (shrink)

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”.

Rome and Carthage had established peaceful diplomatic relations before 300 b.c. — as early as the close of the sixth century according to Polybius, whose dating there no longer seems good cause to doubt. A second treaty was struck probably in 348. Both dealt essentially with traders' and travellers' obligations and entitlements, so any military or political terms sprang from that context. In both, the Carthaginians agreed to hand over any independent town they captured in Latium. In the first treaty (...) they were not to establish a fort in Latium either; in the second, the Romans were not to found a city in Carthaginian Africa, Spain or Sardinia. But independent military considerations are the stuff of a third treaty concluded during Rome's war with Pyrrhus. Rome and Carthage now pledged each other military aid in certain circumstances, as we shall see. And ‘geopolitical’ concerns of a very broad kind imbued a treaty which was reported by the third-century historian Philinus of Agrigentum. By this, he stated, ‘the Romans must keep out of the whole of Sicily, the Carthaginians out of Italy’ . This is Polybius' citation of Philinus' allegation; Polybius himself then roundly rejects the very existence of such a pact and declares himself at a loss to understand how his predecessor could record it, but modern scholarship is no longer all that ready to accept his view. A strong majority of historians prefer to follow the Agrigentine, and many see 306 b.c. as the likely year for the agreement because Livy records a ‘renewal’ then of a foedus with Carthage. (shrink)

The two epigraphical monuments which have preserved parts of the treaties of alliance between Athens, on the one hand, and Rhegion and Leontinoi, respectively, on the other, must be studied together, for both treaties had their old preambles erased in 433/2 and their validity reaffirmed as of that year. The new preambles, both dating from the same day, were inscribed in the erasures and juxtaposed, somewhat awkwardly, before the body of the old texts thatstill remained.

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)

Arguing from a sort of reasonable Protestant ethic, Henry offers a worthwhile and sometimes quite practical analysis of a Christian social ideal. In Henry's approach, no "prattling about love" can take the place of justice when the latter is what is needed.—D. J. B.

This work provides an interesting, though sometimes rather sweeping, demonstration that the metaphysical problem of the same and the other is also the central problem of literature and literary criticism. The author defends the analogical imagination as the symbolic counterpart of participation in Platonic metaphysics.--D. C. B.

Our hospital routine requires that all new admissions must be asked about their code status. It is not uncommon for an otherwise healthy patient to request that a do-not-resuscitate order be placed in their chart. Presumably, these patients who wish to have a DNR order are acting on the belief that should an unforeseen, irreversible condition occur that leads to a cardiac arrest, they would not want to undergo resuscitation. Tragically, we have witnessed several instances in which potentially life-saving interventions (...) were withheld in viable patients in non-arrest settings for reversible conditions because the patients had a DNR order in the chart. Unfortunately, this happens when the treating physicians are not aware of the limited scope of a DNR order and instead use the order as a blanket prohibition against all components of resuscitation. This communication failure is due to misconceptions that patients and their physicians have with regard to such orders. The medical community is well overdue to improve the end-of-life decisions offered to patients beyond relying on the outdated term DNR.LIMITATIONS OF DNR ORDERSDespite the major advances in critical care medicine in the past few decades, doctors have not substantially improved their ability to address end-of-life decisions any better than by using the all-encompassing term DNR. Currently, the term is generally accepted as an order to prohibit the use of interventions to reverse a cardiac or pulmonary arrest.1 2 What is frequently forgotten with the DNR order is that ….
