Linguistics Landscape: a Cross Culture Perspective
This paper was to aim in discussing the linguistic landscape. It was the visibility and salience of languages on public and commercial signs in a given territory or region (Landry and Bourhis 1997). The linguistic landscape has been described as being somewhere at the junction of sociolinguistics, sociology, social psychology, geography, and media studies. It is a concept used in sociolinguistics as scholars study how languages are visually used in multilingual societies, from large metropolitan centers to Amazonia. For example, some public signs in Jerusalem are in Hebrew, English, and Arabic (Spolsky and Cooper 1991, Ben-Rafael et al., 2006). Studies of the linguistic landscape have been published from research done around the world. The field of study is relatively recent; the linguistic landscape paradigm has evolved rapidly and while it has some key names associated with it, it currently has no clear orthodoxy or theoretical core
The Freezing Rotation Illusion
The freezing rotation illusion arises when a figure is continuously rotating in front of a back and forth rotating ground. The term “freezing rotation” designates the decrease in the perceived rotation speed of a figure when the figure and the ground are turning in equal directions. Subjects had to estimate the rotation speed of a continuously turning figure while the ground was either turning opposite to or with the figure. Their estimations of the figure’s speed were significantly lower, when the ground was moving in the same direction as the figure. In control experiments subjects had to estimate the ground’s speed while the figure was turning opposite to or with the ground. Overall, their estimations of the rotational speed of the ground were not significantly influenced by the rotational direction of the figure

Call-by-name Gradual Type Theory
We present gradual type theory, a logic and type theory for call-by-name
gradual typing. We define the central constructions of gradual typing (the
dynamic type, type casts and type error) in a novel way, by universal
properties relative to new judgments for gradual type and term dynamism, which
were developed in blame calculi and to state the "gradual guarantee" theorem of
gradual typing. Combined with the ordinary extensionality () principles
that type theory provides, we show that most of the standard operational
behavior of casts is uniquely determined by the gradual guarantee. This
provides a semantic justification for the definitions of casts, and shows that
non-standard definitions of casts must violate these principles. Our type
theory is the internal language of a certain class of preorder categories
called equipments. We give a general construction of an equipment interpreting
gradual type theory from a 2-category representing non-gradual types and
programs, which is a semantic analogue of Findler and Felleisen's definitions
of contracts, and use it to build some concrete domain-theoretic models of
gradual typing
Banking in General Equilibrium with an Application to Japan
Japan has now experienced over a decade of slow growth and deflation. This period has also been associated with protracted problems in the banking sector. A wide range of measures have been tried in to restore health in the banking sector including recapitalization, the extension of 100% guarantees to all deposits, and central bank purchases of shares held by banks. It has also argued that ending deflation is an important ingredient in restoring banking sector health. This paper develops a general equilibrium of the banking sector. In our model the banking sector produces an intermediate good that is used to produce investment goods and a variable fraction of consumption goods. We then assess the implications of alternative policies designed to assist the banking sector in terms of their implications for welfare and the size and profitability of the banking sector.
