Researches have shown that most effort of today’s software development is maintenance and evolution. Developers often use integrated development environments, debuggers, and tools for code search, testing, and program understanding to reduce the tedious tasks. One way to make software development more efficient is to make the program more readable. There have been many approaches proposed and d...

The epidemiologist faces two problems when ties. In June 1985, only four representatives had any attempting to gauge the prevalence of MDMA use. First, comment at all about MDMA. Chicago's representative users are still rather uncommon. This means that a general stated that "MDMA... has yet to show any signs of survey of Americans will fred only a few percent, at most, widespread availability."...

prospective studies of the potential health consequences of trade and investment treaties, such as the trans-pacific partnership, are critical. these studies can make visible to trade policy-makers the potential negative impacts associated to such treaties and can influence the outcomes of such negotiations. however, few researchers have examined retrospectively the consequences of trade agreem...

This commentary examines Huron and Veltman’s article from the perspective of historical musicology. The following issues are discussed: • The authors regard modes as conceptual categories of the medieval listener, which seems unlikely on historical and theoretical grounds. • Pitch class profiles are not a good way of capturing the melodic nature of the modes. • The diatonic rather than the chro...

The analysis of spontaneous resting state neuronal activity is assumed to give insight into the brain function. One noninvasive technique to study resting state activity is electroencephalography (EEG) with a subsequent microstate analysis. This technique reduces the recorded EEG signal to a sequence of prototypical topographical maps, which is hypothesized to capture important spatio-temporal ...

We are most grateful for the comments made by Earl (2014) on our paper, Frey and Gallus (2014). In particular, we are pleased that we can fully agree on the fundamental point we wanted to make: decisions by individuals (as well as by organizational units) do not map directly and in an unchanged way to the macro level. Rather, the aggregation process linking the microand the macro-level must be ...

In 1937, Ronald Coase argued that firms will exist only in environments in which firms perform better than markets could. To create space for firms, Coase suggested that some environments might be plagued by “transaction costs” that cause markets to perform poorly. Coase’s paper was to become the cornerstone of the economic theory of the firm (i.e., the “make or buy” decision: which activities ...

This paper proposes and evaluates a model of supply chains as networks of auctions. In this model, companies are represented according to the first level of the Supply Chain Council’s SCOR model and the trading strategy of the agents is adapted from a model proposed by Steiglitz and colleagues. Specifically, the highest level of SCOR treats a company as comprising three functions, namely Source...

In a recent Physical Review Letter [1] Garcia and Nieto Vesperinas (GNV) dispute the claim of perfect lensing made in [2]. GVN claim that the solutions proposed in [2] imply infinite energy density and are therefore inadmissible. They also claim that finite absorption leads to catastrophic collapse of the amplifying solutions vital to focussing. GNV calculate in equation (6) of their Letter the...
