Standard definitions of procrastination underscore the irrational nature of this habit, a critical criterion being that the procrastinating individual delays despite expecting to be worse off for the delay. However, an examination of more than 175 items in 18 procrastination scales reveals that they do not address such a forward-looking criterion. Consequently, scales run the risk of not separating maladaptive and irrational delays from other forms of delay. We propose that forward-looking considerations may not be the best way of operationalizing (...) the irrationality involved in procrastination and argue that scales should instead focus on past negative consequences of unnecessary delay. We suggest a new scale to measure such procrastination-related negative consequences and demonstrate that this scale, used separately or combined with established procrastination scales, performs better in predicting negative states and correlates to procrastination than established scales. The new scale seems to be helpful in separating trivial forms of unnecessary delay from maladaptive forms and hence represents a potentially valuable tool in research and clinical/applied efforts.

Most theories of learning consider inferring a function f from either observations about f or, questions about f. We consider a scenario whereby the learner observes f and asks queries to some set A. If I is a notion of learning then I[A] is the set of concept classes I-learnable by an inductive inference machine with oracle A. A and B are I-equivalent if I[A] = I[B]. The equivalence classes induced are the degrees of inferability. We prove several results about (...) when these degrees are trivial, and when the degrees are omniscient. (shrink)

The interaction between cavity modes and optical transitions leads to new coupled light-matter states in which the energy is periodically exchanged between the matter states and the optical mode. Here we present experimental evidence of optical strong coupling between modes of individual sub-wavelength metamaterial nanocavities and engineered optical transitions in semiconductor heterostructures. We show that this behaviour is generic by extending the results from the mid-infrared to the near-infrared. Using mid-infrared structures, we demonstrate that the light-matter coupling occurs at the (...) single resonator level and with extremely small interaction volumes. We calculate a mode volume of 4.9 × 10 from which we infer that only ~2,400 electrons per resonator participate in this energy exchange process. (shrink)

In this article, we look at the contested role of in-house lawyers in regulated organisations in the financial sector. A recent Financial Conduct Authority consultation on whether to designate the head of legal of banks, insurance companies and other financial firms as ‘Senior Managers’ and the decision which flowed from it, reflected a flawed view of lawyers as a neutral technocracy of mere legal technicians; we show how the FCA’s decision is potentially damaging to the public interest and failed to (...) take into account that in-house lawyers are often important decision-makers and influencers within their organisations. We put the case for an alternative view; that in-house lawyers are professionals, with agency that requires them to act in accordance with ethical norms and means they should be made more accountable for their conduct.

This article deals with the Katta Langar manuscript, which is known as one of the earliest Qur'ān copies attributed to III. Caliph Uthman. The study consists of an introduction, a conclusion and two sections. The introduction section begins with the information that the Katta Langar Mushaf which is called by this name relative to the Katta Langar village of Uzbekistan, is in the library of the Tashkent Uzbekistan Muslims Administration. Only ninety-seven pages of the mushaf, which was lost for a (...) period, have survived. Since twelve of these leaves appear again in Katta Langar, they are meant as the Katta Langar manuscripts. Therefore, this article not only aims to examine in detail all the extant leaves of the mushaf but also the twelve leaves, which are known today as the Katta Langar manuscripts. Although the research done so far has made it clear that this mushaf is not one of the copies of Uthman, the mushaf has been the subject of many studies. The first of the studies on the Katta Langar Mushaf was published by M.E. Masson, while the most detailed work belongs to Efim Rezvan. Existing studies on the mushaf are methodologically either a publication or a catalogue study. In this study, the Katta Langar copy was compared with the sources of the mushaf literature and discussed more comprehensively. (shrink)
