The Linguistic Politeness Having Seen on the Current Study Issue
The current issue is overviewed in this paper about the linguistics politeness. Positive politeness strategies seek to minimize the threat to the hearer\u27s positive face. These strategies are used to make the hearer feel good about themselves, their interests or possessions, and are most usually used in situations where the audience knows each other fairly well. In sociolinguistics and conversation analysis (CA), politeness strategies are speech acts that express concern for others and minimize threats to self-esteem ("face") in particular social contexts. Being polite means being aware of and respecting the feelings of other people. Politeness can and will improve your relationships with others, help to build respect and rapport, boost your self-esteem and confidence, and improve your communication skills. Importance of Politeness in Life. Politeness is a great virtue. But a polite person will always please others with his polite behavior and good manners. Politeness means consideration for the feelings of others. Politeness is one of the central features of human communication. It is a human phenomenon, yet expressed differently in different cultures. Positive politeness refers to an atmosphere of inclusion and mutuality created by linguistic means such as compliments, encouragement, joking, even the use of "white lies.

City regions and polycentricity: the East Midlands urban network
The aims of this paper were to clarify the meaning of the terms city region and polycentricy and to then examine evidence on urban centres in the East Midlands to see how far these terms describe the present configuration of the region
Optimising Matrix Product State Simulations of Shor's Algorithm
We detail techniques to optimise high-level classical simulations of Shor's
quantum factoring algorithm. Chief among these is to examine the entangling
properties of the circuit and to effectively map it across the one-dimensional
structure of a matrix product state. Compared to previous approaches whose
space requirements depend on , the solution to the underlying order-finding
problem of Shor's algorithm, our approach depends on its factors. We performed
a matrix product state simulation of a 60-qubit instance of Shor's algorithm
that would otherwise be infeasible to complete without an optimised
entanglement mapping.Comment: 8 pages, 2 figures, 2 tables. v2 using PDFLaTeX compiler. v3 to

Exchange Rate Models Are Not as Bad as You Think
Standard models of exchange rates, based on macroeconomic variables such as prices, interest rates, output, etc., are thought by many researchers to have failed empirically. We present evidence to the contrary. First, we emphasize the point that "beating a random walk" in forecasting is too strong a criterion for accepting an exchange rate model. Typically models should have low forecasting power of this type. We then propose a number of alternative ways to evaluate models. We examine in-sample fit, but emphasize the importance of the monetary policy rule, and its effects on expectations, in determining exchange rates. Next we present evidence that exchange rates incorporate news about future macroeconomic fundamentals, as the models imply. We demonstrate that the models might well be able to account for observed exchange-rate volatility. We discuss studies that examine the response of exchange rates to announcements of economic data. Then we present estimates of exchange-rate models in which expected present values of fundamentals are calculated from survey forecasts. Finally, we show that out-of-sample forecasting power of models can be increased by focusing on panel estimation and long-horizon forecasts.
Robust CNOT gates from almost any interaction
There are many cases where the interaction between two qubits is not
precisely known, but single qubit operations are available. In this paper we
show how, regardless of an incomplete knowledge of the strength or form of the
interaction between two qubits, it is often possible to construct a CNOT gate
which has arbitrarily high fidelity. In particular, we show that oscillations
in the strength of the exchange interaction in solid state Si and Ge structures
are correctable.Comment: 5 pages, 2 figure
