Social Media as a Bridge between Teaching and ResearchStephen Kinsella
Here's a talk I gave on Tuesday to a symposium on Social Media with Prof. Gerry McKiernan, revolving around using social media tools like this blog, the text messaging software, and The Twitter, etc, to communicate and interact with my students.
A Matching Model with Friction and Multiple CriteriaStephen Kinsella
We present a model of matching based on two character measures.
There are two classes of individual. Each individual
observes a sequence of potential partners from the opposite class.
One
measure describes the "attractiveness" of an individual.
Preferences are common according to
this measure: i.e. each individual prefers highly attractive partners and all individuals
of a given class agree as to how attractive individuals of the opposite class are. Preferences are
homotypic with respect to the second measure, referred to as "character" i.e.
all individuals prefer partners of a similar character.
Such a problem may be interpreted as e.g. a job search problem in which the classes
are employer and employee, or a mate choice problem in which the classes are male and
female.
It is assumed that
attractiveness is easy to measure and observable with certainty. However,
in order to observe the character of an individual, an interview (or courtship) is required.
Hence, on observing the attractiveness of a prospective partner an individual must decide whether he/she wishes
to proceed to the interview stage. Interviews only occur by mutual consent. A pair can only be formed
after an interview. During the interview phase the prospective pair
observe each other's
character, and then decide whether they wish to form a pair.
It is assumed that mutual acceptance is required for pair formation to
occur. An individual stops searching on finding a partner.
This paper
presents a general model of such a matching process. A particular case is
considered in which character "forms a ring" and has a uniform distribution.
A set of criteria based on the concept of a subgame
perfect Nash equilibrium is used to define the solution of this particular game. It is shown that
such a solution is unique. The general form of the solution is derived and a procedure for finding
the solution of such a game is given.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

the growth rate appropriately compounded.CP the future is
the square root of the present multiplied by the growth rate

15. A DERIVATION
• Now let i be a rate of interest, k a rate of generalized risk, d
the rate of default risk and m the rate of market risk, with g
representing the rate of net interest (we choose ‘g’ because
we will argue later that the rate of net interest should reflect
the rate of growth). Then we have:
= √(k2 + g2), and
•i
= √(d2 + m2), so that
•k
i = √( d2 + m2 + g2)
•
16. IDEA
• Herewe see that we have defined a distance function, D.15
The basic idea is that the risk factor is a vector the length of
which measures the distance from the point of zero risk.
17. STRUCTURE OF THE
QUADRANGLE
• Structure of the Quadrangle: we want to examine the
relationships between the markets, and between risks and
returns.
• First
we need to define the rates of interest in the four
submarkets, the overnight market and the stock market. Then
we will relate these rates to the real economy; this will give us
the structure in which economic activity takes place. At that
point we can turn to behavioral equations and determine
employment and output, the debt equity ratio and the overall
holding of securities in portfolios.
18. CENTRAL BANK & RATE
STRUCTURE
• Some simple equations can be written, starting with one for
the Fed setting the overnight interbank rate, then moving to
the short-term market for Treasuries:
• i0 = D(0, 0, i0*)
• iGS = D(0, mS, gN)
• over the cycle:
• iPS
= D(dS, mS, gN) where gn is the rate of growth of
capacity employment
19. • Now we can write equations for the long-term market, for
corporate and government fixed capital
• iGL = D(dG, mL, gY)
• iPL = D(dP, mL, gY)
• Next we turn to equity markets
• re = D(me. rF), [this is a vector combination]
