Why might it be necessary for an organization to alter its targeting strategy over time? Use a
specific organizational example in your response.
Solution
the above said is correct, and some times they need to rethink about their decisions. the reason
the complete picture and the situations are different from our assumptions. so, when ever we
thinks that we took a wrong decision, there is nothing wrong to rethink about the strategy.
there are many examples in the history; one is from Bajaj two wheelers in India.
initially they only stick for producing scooters, and they does not go with bikes. but later they
changed their openion and started the production of bikes. they are the third largest two wheeler
seller in Indian market.
so,when the time comes one has to evaluate and analyse his strategies and if he finds any gaps or
problems he can change them..

CHAPTER 4Section 4.1 Introduction to HIV/AIDS
4.1 Introduction to HIV/AIDS
In June 1981, the U.S. Centers for Disease Control and Prevention (CDC) published a report on the clinical condition of five young male homosexuals who all presented the same unusual group of symptoms (CDC, 1981b). Although these individuals had previously been healthy,
they were all diagnosed with Pneumocystis carinii pneumonia (PCP), a rare condition associated
with a severely compromised immune system. Three weeks later, another report from the CDC
documented 26 gay men in New York and California with compromised immune systems from
both PCP and the cancer Kaposi sarcoma (CDC, 1981a). Although initially given the acronym GRID
(gay-related immune deficiency, because of the sexuality of the men in these initial cases), this
disease eventually came to be known by the acronym HIV/AIDS.
Clinical Overview
HIV stands for human immunodeficiency virus. This term means several things: (a) It is a condition
that can only infect humans beings (H); (b) it compromises immune systems (I); and (c) it is a
virus (V), an infectious organism that invades living cells. Because HIV is a viral infection (as is the
common cold), it results from exposure to a pathogen. However, HIV is more threatening than a
cold virus because the human body is unable to fight it off. Once infected, people never recover,
even though they may be asymptomatic. And, as with other chronic diseases, they must live with
the condition throughout their lives.
Although our bodies have built-in mechanisms designed to fight disease, HIV attacks CD4-positive
T cells, which in human immunology is a type of white blood cell vital to fighting off infections and
foreign microbes. HIV launches its attack by first invading these cells so it can replicate; afterward,
it destroys the cells. Eventually, when a person’s CD4 cells fall below a specified level, the immune
system has been compromised. This criterion leads to a diagnosis of AIDS, which is an acronym for
acquired immunodeficiency syndrome.

Introduction
Diseases and other health conditions are classified in several meaningful ways
Classification can lead to prevention and control strategies
Classification of Diseases and Health Problems
In community health, diseases are usually classified as:
Acute or chronic (<3 or >3 months)
Communicable or noncommunicable
Communicable versus Noncommunicable Diseases
Communicable (infectious) diseases – those diseases for which biological agents or their products are the cause and that are transmissible from one individual to another
Noncommunicable (noninfectious) diseases – those illnesses that cannot be transmitted from one person to another
Identifying cause is difficult because many factors can contribute
Acute versus Chronic Diseases and Illnesses
Diseases classified by duration of symptoms
Acute – diseases in which peak severity of symptoms occurs and subsides within 3 months
Can be communicable or noncommunicable
Chronic – diseases or conditions in which symptoms continue longer than 3 months
Can be communicable or noncommunicable
Communicable Diseases
Infectivity: ability of a biological agent to enter and grow in the host
Agent: cause of disease or health problem
Host: susceptible person or organism invaded by an infectious agent
Environment: factors that inhibit or promote disease transmission
Pathogenicity: capability of a communicable agent to cause disease in a susceptible host

Solution
Power of source = P
INtensity at r1 = I1 = P/4*pi*(r1)^2
Intensity at r2 = I2 = P/4*pi*(r2)^2
Now, 10log(I1/I2) = 4.12
20log(r2/r1) = 4.12
r2/r1 = 1.606
but r2 - r1 = 0.77
so r2 = 1.606(r2 - 0.77) = 1.606 r2 - 1.2366

C. The database should be the same before and after a transaction has occurred.
D. Databases should be available to multiple users at the same time without endangering the
integrity of the data
Solution
B. Transaction persistence means that the state of the database security is the same after a
transaction has occurred. In addition, there is no risk of integrity problems. Answer A is incorrect
because it does not define transaction persistence. Answer C is wrong because transaction
persistence does not state that the database should be the same before and after a transaction.
Answer D is incorrect because even though databases should be available to multiple users at the
same time without endangering the integrity of the data, that fact is not a definition of transaction
persistence.

Toxaphene is an insecticide that has been identified as a pollutant in the Great Lakes ecosystem.
To investigate the effect of toxaphene exposure on animals, groups of rats were given toxaphene
in their diet. The article “Reproduction Study of Toxaphene in the Rat” (J. of Environ. Sci.
Health, 1988: 101-126) reports weight gains (in grams) for rats given a low dose (4 ppm) and for
control rats whose diet did not include the insecticide. The sample standard deviation for 23
female control rats was 32 g and for 20 female low-dose rats was 54 g. Does this data suggest
that there is more variability in low-dose weight gains than in control weight gains? Assuming
normality, carry out a test of hypotheses at significance level .05

The number of passengers (including the driver) in cars that cross a certain bridge is a random
variable Y having mean E(Y) = 2.7 and variance V(Y) = 1.2. The toll on the bridge is $3.00 per
car plus $0.50 per person in the car. The mean and variance of the total amount of money that is
collected from a car that crosses the bridge are:
(a) mean = $8.60, variance = $.30
(b) mean = $4.35, variance = $3.30
(c) mean = $8.60, variance = $.60
(d) mean = $4.35, variance = $.30
(e) mean = $1.35, variance = $.30
Solution
The amount they pay in terms of Y is
A = 3.00 + 0.50Y
Thus,
E(A) = E(3.00 + 0.50Y) = 3.00 + 0.50E(Y) = 3.00 + 0.50*2.7
E(A) = 4.35
Also,
Var(A) = Var(3.00 + 0.50Y) = 0.50^2 Var(Y) = 0.50^2 * 1.2
Var(A) = 0.30

d) How does the environment affect sexual phenotype in turtles and alligators? (SHOW WORK
& EXPLAIN)
Solution
a) Chromosomal Theory of Inheritance is a fundamental theory of genetics.Thomas Hunt
Morgan establishes the Chromosomal theory of heredity.In 1907 Morgan was based on
experiments by using Drosphila melanogaster or fruit flies. Drosphila have red eyes.Red eye
colour is dominant.Morgan discovered a recessive mutation that caused white eyes.
B) Boveri-Sutton chromosome theory identifies chromosomes as the carriers of genetic material
which states that chromosomes carry the unit of heredity.
McClung : A zoologist studied the behaviour of chromosomes in the sex cells and discovered the
sex determining chromosome.
Stevens: Stevens was interested in the process of sex determination.
Morgan proposed the Chromosomal Theory of Heredity by using a common fruit fly.
C) Sex determination is a biological system that determines the development of sexual
characteristics.
XX-XO types : In this type females have two homomorphic sex chromosomes XX ,male have
one sex chromosome XO. This type of sex determination seen in cockroaches.
XX-XY : This sex determination occurs in human beings.Females have two identical
homologous sex chromosome XX and males have XY.
ZZ-ZW : Females carry two types of sex chromosome ZW heterogametic and males carry ZZ
homogametic. This type of sex determination occurs in fishes reptiles.
D) Sex determination in reptiles are classified into two categories that is genotypic sex
determination and temperature dependent. Environmental sex determination in which
temperature is a crucial factor in embryonic development. In many turtle species eggs from
cooler nests hatch males and from warmer nests hatch the females..

Prove that the chromatic number of a cycle graph_n of odd length equals 3.
Solution
Chromatic Number: The chromatic number of a graph G is the least k for which a k-coloring of
G exists.
First note that the chromatic number must be at least 2 for any graph which has an edge in it,
including all cycles. We now prove the theorem by induction on n. We will consider two base
cases, C3 and C4. C3 is isomorphic to K3 which has chromatic number 3. C4 can be colored
with two colors by giving opposing corners of the square the same color. For n > 4, we can take
a coloring of Cn-2 and insert 2 adjacent vertices and edges and then color the new vertices
appropriately to get a coloring of Cn. Thus the chromatic number of Cn is not greater than that of
Cn-2. In the case where n is odd, note that if Cn had chromatic number 2, we could remove two
adjacent vertices and edges to get a 2-coloring of Cn-2 which contradicts the inductive
hypothesis since n-2 must be odd if n is odd. Therefore for odd numbers the chromatic number
will be 2+1 = 3..

Many non-scientists have focused their criticism of evolution on the fact that even scientists have
criticized Darwin’s theory. Is this true? In what respect did Darwin get it wrong, or maybe in
what way has Darwin’s theory been modified?
Solution
The \"Origin of Species\" of Darwin described about the heritable change in an organism over a
period of time due to natural selection. Scientists also criticized of Danwin\'s opinion on use and
disuse theory. At the time of Origin of species, Darwin do not know about the existed of
microorganisms and his theory of tree of life became wrong. Pangenesis theory of Darwin also
became wrong as he do not know anything about genetics..

iQ2 In a study about children?s pocket money, two samples of schoolchildren were asked how
much money they received each week. In one sample, of size 80, the mean is ?6.65. In the other
sample, of size 41, the mean is pound 8.21. Calculate the mean based on the combined sample.
Give your answer correct to two decimal places. (Do NOT include the pound sign in your
answer.)
Solution
n1=80 x1=6.65
n2=41 x2=8.21
combined mean = (n1*x1+n2*x2)/( n1+n2)
=( 80*6.65+41*8.21) /( 80+41)
=868.61/121
=7.1785
Combined mean =7.18 ( two decimals).

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.
