What’s Love Got To Do With It?
The Evolution of Human Mating
By Meredith F. Small
Reviewed By Michael S. Kimmel
When Tina Turner first bitterly asked “What’s love got to do with it?” her voice was so drenched
with pain and regret, the listener knew better than to believe her.
Not so Meredith Small. A physical anthropologist whose main research has been on primate
mating behavior, Small joins a coterie of such writers as Robert Ardrey, Desmond Morris and
Lionel Tiger, who have sought to make evolutionary biology the foundation of studies of sexual
behavior.
In “What’s Love Got To Do With It,” Small argues that we’re genetically programmed to
experience sexual pleasure; hard-wired to search for young, attractive mates; driven to copulate
“Way down deep, underneath all the love and lust, underlying the attachment and intimacy, is
DNA pushing us along”
Like those male writers, she claims that our genetic predisposition toward reproductive success is
the driving force of our sex-seeking behavior. And like them, she assumes that sex is a constant,
universal and relatively unchanging experience. But unlike them, Small places no value on
judgments on the strategies that individuals may adopt to achieve that reproductive success.
Women, she argues, are as sexual as men; homosexuality is as “normal” as heterosexuality.
Small exposes many of her colleagues’ conclusions as based more on myth than on evolution.
Take, for example, the familiar canard that men are “naturally” predisposed toward promiscuity,
while women are “naturally” monogamous. Males’ prodigious sperm production, the argument
goes, means that it is in men’s interest to fertilize as many women as possible. But women
produce only one egg at a time, and gestation and child care take an extraordinarily long time,
which means that it is in their interest to mate with only one man for life.
Not only do such arguments assume what they are trying to explain, but their assumptions are
wrong to begin with. Sperm and eggs do not have little personalities, complete with ambitions
and motivations. What’s more, the evidence actually tilts the other way. Female humans are
among the only mammals who conceal estrus; that is, they do not go into “heat” when they are
sexually receptive. They are potentially sexually receptive all through their cycle. What’s more, a
woman has a clitoris, which “exists only to receive and give off sexual pleasure.” What could be
the evolutionary function of that?
Small argues that it is just as likely that women may be designed to maximize their reproductive
chances by promiscuity. If they have sex with a large number of male partners, they can ensure
that their offspring will have a significant number of men who believe that they are the father,
and who will, therefore, protect the baby and provide it with food.
“The ability to move from male to male certainly improves a female’s chance of finding the best
genes for her future offspring,” Small writes.
Males, by contrast, wo.

A series RL circuit includes a 9.05-V battery, a resistance of R = 0.pdfarishmarketing21
A series RL circuit includes a 9.05-V battery, a resistance of R = 0.755 , and an inductance of L
= 2.97 H. What is the induced emf 1.33 s after the circuit has been closed?
So, basically, I tried solving this equation using an RL circuit formula: I = emf/R(1-e^-t/(L/R))
and used V=IR to solve for the current, for which I plugged it back in to obtain the emf. I got an
answer of about 31, which was wrong. If you could help me on this, it would make my day!
Solution
tau = L/R = 2.97/0.755 = 3.9337
V = V0*e^(-t/tau)
V = 9.05*e^(-1.33/3.9337)
V = 6.453 V.

What is the dangling pointer? Explain with a proper example.
Solution
A dangling pointer is a pointer which nce pointed to some data, but because of memory
deallocation, points to an invalid or null data.
Example:
Suppose we declare and allocate some memory to a pointer:
char *temp = malloc(some_size);
Then we de-allocate the memory allocated to the pointer temp by,
free (temp);
After execution of the above statement, temp becomes a dangling pointer..

What is the Surface characterization techniques of Fourier-transform.pdfarishmarketing21
What is the Surface characterization techniques of Fourier-transform infrared spectroscopy
(FTIR) and Optical Imaging and Spectroscopy (microscopy, TIRF)
explain what are they measuring, their uniqueness, working principle briefly
Solution
Fourier transform infrared spectroscopy (FTIR) is a powerful analysis tool for characterizing and
identifying organic molecules. It is the spectroscopic technique that is the most widely used for
determining the characteristics of new membranes. In attenuated total reflectance mode, this type
of spectroscopy enables functional groups present over a depth of about 1 m to be identified.
During ATR analysis, the sample is kept in contact with a crystal allowing total internal
reflection. An infrared ray arrives at the crystal where the material under study has been placed.
The internal reflection of the ray in the crystal gives rise to an evanescent wave which, at each
reflection, continues beyond the surface of the crystal and penetrates the sample over about 1 m.
The penetration depth depends on the wavelength, the angle of incidence of the beam on the
crystal, and the nature of the crystal.
Spectra are thus obtained (curves of absorbance vs. wavelength) that have absorption peaks
characteristic of the functions present at the membrane surface.
FTIR-ATR is a sensitive, nondestructive method that can be used qualitatively and
quantitatively. However, it requires prior drying of the membrane sample.
One of the applications of FTIR-ATR is the characterization of modified surfaces. In this case,
the spectra show bands characteristic of the basic membrane with, in most cases, bands
characteristic of the new functional groups related to the modification. FTIR-ATR also enables
the efficiency of membrane cleaning to be assessed .
This method can also be used to analyze the adsorption of macromolecules at the membrane
surface and to check whether the conformation of the adsorbed compounds (e.g., proteins) has
been modified by comparing the spectra of the adsorbed product with those of the same product
in solution . When the deposits are very small, however, it is difficult to determine the presence
of fouling agents; this necessitates the use of elaborate data-processing methods that eliminate
the contributions of the membrane and water from the raw spectra.
UNIQUENESS:
There are three principal advantages for an FT spectrometer compared to a scanning (dispersive)
spectrometer.
TIRF
Total internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical
technique that provides for the excitation of fluorophores in an extremely thin axial region
(‘optical section’). The method is based on the principle that when excitation light is totally
internally reflected in a transparent solid (e.g., coverglass) at its interface with liquid an
electromagnetic field, called the evanescent wave, is generated in the liquid at the solid-liquid
interface and is the same frequency as the excitation light. Since the inte.

What is the running time complexity and space complexity of the following procedure (n = R -
L + 1). Explain your answer. def foo(V, L, R): if L==R: return V[L] mid = (L+R)//2 m1 = foo(V,
L, mid) m2 = foo(V, mid+1, R) if m1==m2: return ml count1, count2 = 0, 0 for i in range(L,

count2 > (R-L+D/2: return m2 return None
Solution
We are removing half the data at each turn so time complexity is O(log n).
We divide it into 2 till we find 1. Thus,
1= N/2x
2x = N
Thus x = log2 n.

What are the security requirements and challenges of Grid and Cloud .pdfarishmarketing21
What are the security requirements and challenges of Grid and Cloud Computing?
Solution
security issues:
A. Policies:
1) Inside Threats: good supervision should be done for having trusted employees .
2) Access Control:Digital signature can be implemented
for access control.
3) System Portability: The problem of vendor lock-in
should be handled .
B. Software Security:
1) Virtualization technology: up to date version of
virtualization product should be installed for the
security reasons.
2) Host Operating System:should be up to date and
secure from hackers
3) Guest Operating System: should be up to date and
secure from hackers
4) Data Encryption:should be done on all the data for
its safety.
C)Physical security:
1) Backup:Either a backup plan should be provided
automatically for each customer, or they can use the
plans provided elsewhere in the cloud.
2) Server Location:It should be at appropriate place. Room should have adequate space and
isolated. A
Cooling System and Fire Suppression System should
be installed there.
3) Firewall: Cloud Computing service providers should
provide a complete firewall solution to their clients.
Challenges:
A)No clear standard:Grid computing
uses various standards, but all grids are
not use same standards. Example all grid
operating system such as Linux, Apache,and My SQL are using WSRF,
WWW, SOAP and XML standards.
B)Distributed computing Vs Grid
computing: Grid computing involves
dynamic virtual organisation, resource
sharing and peer to peer computing. The
Grid intends to make access to
computing power, scientific data
repositories and experimental facilities
as easy as the Web makes access to
information. Same all facilities provide
the grid computing. So it is a challenge
for grid computing.
C)Lack of grid enabled software: The
software, which are enabled the grid
computing are less, It has limited
software on Grid. Much software has
not copyright issues and source code of
licence. It is need for more company
developing grid-enabled version, need
more developers on grid development
and need to develop open source
software.
D)Sharing Resources between Various
types of Services:Grid used for
sharing resource from various sites and
grid hosts. It handles a massive amount
of data as a grid platform. A lot of sites
and multiple servers gathered there it is
so complex infrastructure. It provides
difficulty for hardware resource sharing
within virtual organisation..

The organization of interrupted genes is often conserved between spe.pdfarishmarketing21
The organization of interrupted genes is often conserved between species. What does this mean
and what is an example of this conservation (diagram/explain)?
Solution
First we have know about interrupted genes is often conserved between species,the intricate
cellular machinery that converts genetic information into functional protein and RNA molecules
and the many ways in which gene expression is regulated by the cell,we discuss some of the
ways that genes and genomes have evolved over time to produce the vast diversity of modern-
day life forms on our planet uncovering an astonishing wealth of information about the family
relationships among organisms and evolutionary mechanisms,but the great revelation of the past
20 years has been the discovery that the actual nucleotide sequences of many genes are
sufficiently well conserved that homologous genes.
The recognition of sequence homology has become a major tool for inferring gene and protein
function thus it is often possible to predict the function of a gene in humans for which no
biochemical or genetic information is available simply by comparing its sequence to that of an
intensively studied gene in another organism.
Gene sequences are often far more tightly conserved than is overall genome structure as
discussed features of genome organization such as genome size,cells do not have specialized
mechanisms for creating changes in the structures of their genomes evolution depends instead on
accidents and mistakes.
Introns can be detected by the presence of additional regions when genes are compared with their
RNA products by restriction mapping or electron microscopy
The positions of introns are usually conserved when homologous genes are compared between
different organisms but the lengths of the corresponding introns may vary greatly..

circular clearing within a lawn of growth; surrounding a disk or colony containing an

Solution
The basic principle of Enrichment is that of selection. Enrichment culture provides favourable
growth conditions for the organism of intrest and unfavourable conditions for the competing
organisms. This technique can be used in many ways. for example, if we want to culture a
thermophile bacteria, incubate the sample at high temperature i.e., at above 55 degrees
centigrade because at that temperature, only the thermophilic bacteria can grow while this
temperature hampers the growth of other bacteria in the sample.
Likewise, enrichment culture may also contains antimicrobial agents to which the selective
organism is resistant hence the required organism\'s growth is facilitated hampering the growth
of other organisms which are not resistant to the antimicrobial agent.
Enrichment culture may also contains pesticides or N2 (used for selective growth of nitrogen
fixing bacteria) depending upon the type of microorganism selected.
Hence the Answer is a lawn of bacteria is prepared and filter discs containing antimicrobial
agents are applied..

Q1) Show what part of SSL that protects against the following attack.pdfarishmarketing21
Q1) Show what part of SSL that protects against the following attacks :-
a. Replay Attack: Earlier SSL handshake messages are replayed.
b. Man-in-the-Middle Attack: An attacker interposes during key exchange, acting as the client to
the server and as the server to the client.
c. IP Spoofing: Uses forged IP addresses to fool a host into accepting bogus data.
Q2) Describe the port forwarding operation. Using an example, describe the cases when it is very
useful, and the cases when it is very dangerous.
Solution
The secure socket layer (SSL) is a computer networking protocol that manages server
authentication, client authentication and encrypted communication between servers ant client
.
PROTACTION FROM REPLAY ATTACK-
The SSL itself is protected againsts replay attack using Medium Access Control ( MAC ). By
using MAC secret and the sequence number it ensures the communication integrity.
ssl handshake protocol
PROTECTION AGAINSTS MAN-IN-THE MIDDLE ATACK-
SSL is based on public/ private key cryptography. This basically means that there is a key pair.
The public key is used for encryption and secret key is used for decryption . A certificate is
basically a public key with a label identifying the owner. So when your browser connects to an
https server , the server will answer with its certificate. The browser checks if the certificate is
valid-
1: The owner information needs to match the server name that the user requested.
2: The certificate needs to be signed by a trusted certification authority.
if one of these condition is not met, the user is informed about the problem.
PROTECTION AGAINSTS IP SPOOFING-
An SSL certificate is specific to the particular domain for which it was created regardless of the
IP address of the doimain. So if a malicious entity want to attempt to redirect trafiic for a certain
website to their own malicious site through IP spoofing techniques. The fake site would not have
a SSL certificate that was accurately registerd to the real website.This can be varified through a
browser by viewing the certificate information and if the wrong address is shown, then the user
will know that they are not on the site they think they are on.Secure Socket Layer Architecture

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.

A series RL circuit includes a 9.05-V battery, a resistance of R = 0.pdfarishmarketing21
A series RL circuit includes a 9.05-V battery, a resistance of R = 0.755 , and an inductance of L
= 2.97 H. What is the induced emf 1.33 s after the circuit has been closed?
So, basically, I tried solving this equation using an RL circuit formula: I = emf/R(1-e^-t/(L/R))
and used V=IR to solve for the current, for which I plugged it back in to obtain the emf. I got an
answer of about 31, which was wrong. If you could help me on this, it would make my day!
Solution
tau = L/R = 2.97/0.755 = 3.9337
V = V0*e^(-t/tau)
V = 9.05*e^(-1.33/3.9337)
V = 6.453 V.

What is the dangling pointer? Explain with a proper example.
Solution
A dangling pointer is a pointer which nce pointed to some data, but because of memory
deallocation, points to an invalid or null data.
Example:
Suppose we declare and allocate some memory to a pointer:
char *temp = malloc(some_size);
Then we de-allocate the memory allocated to the pointer temp by,
free (temp);
After execution of the above statement, temp becomes a dangling pointer..

What is the Surface characterization techniques of Fourier-transform.pdfarishmarketing21
What is the Surface characterization techniques of Fourier-transform infrared spectroscopy
(FTIR) and Optical Imaging and Spectroscopy (microscopy, TIRF)
explain what are they measuring, their uniqueness, working principle briefly
Solution
Fourier transform infrared spectroscopy (FTIR) is a powerful analysis tool for characterizing and
identifying organic molecules. It is the spectroscopic technique that is the most widely used for
determining the characteristics of new membranes. In attenuated total reflectance mode, this type
of spectroscopy enables functional groups present over a depth of about 1 m to be identified.
During ATR analysis, the sample is kept in contact with a crystal allowing total internal
reflection. An infrared ray arrives at the crystal where the material under study has been placed.
The internal reflection of the ray in the crystal gives rise to an evanescent wave which, at each
reflection, continues beyond the surface of the crystal and penetrates the sample over about 1 m.
The penetration depth depends on the wavelength, the angle of incidence of the beam on the
crystal, and the nature of the crystal.
Spectra are thus obtained (curves of absorbance vs. wavelength) that have absorption peaks
characteristic of the functions present at the membrane surface.
FTIR-ATR is a sensitive, nondestructive method that can be used qualitatively and
quantitatively. However, it requires prior drying of the membrane sample.
One of the applications of FTIR-ATR is the characterization of modified surfaces. In this case,
the spectra show bands characteristic of the basic membrane with, in most cases, bands
characteristic of the new functional groups related to the modification. FTIR-ATR also enables
the efficiency of membrane cleaning to be assessed .
This method can also be used to analyze the adsorption of macromolecules at the membrane
surface and to check whether the conformation of the adsorbed compounds (e.g., proteins) has
been modified by comparing the spectra of the adsorbed product with those of the same product
in solution . When the deposits are very small, however, it is difficult to determine the presence
of fouling agents; this necessitates the use of elaborate data-processing methods that eliminate
the contributions of the membrane and water from the raw spectra.
UNIQUENESS:
There are three principal advantages for an FT spectrometer compared to a scanning (dispersive)
spectrometer.
TIRF
Total internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical
technique that provides for the excitation of fluorophores in an extremely thin axial region
(‘optical section’). The method is based on the principle that when excitation light is totally
internally reflected in a transparent solid (e.g., coverglass) at its interface with liquid an
electromagnetic field, called the evanescent wave, is generated in the liquid at the solid-liquid
interface and is the same frequency as the excitation light. Since the inte.

count2 > (R-L+D/2: return m2 return None
Solution
We are removing half the data at each turn so time complexity is O(log n).
We divide it into 2 till we find 1. Thus,
1= N/2x
2x = N
Thus x = log2 n.

What are the security requirements and challenges of Grid and Cloud .pdfarishmarketing21
What are the security requirements and challenges of Grid and Cloud Computing?
Solution
security issues:
A. Policies:
1) Inside Threats: good supervision should be done for having trusted employees .
2) Access Control:Digital signature can be implemented
for access control.
3) System Portability: The problem of vendor lock-in
should be handled .
B. Software Security:
1) Virtualization technology: up to date version of
virtualization product should be installed for the
security reasons.
2) Host Operating System:should be up to date and
secure from hackers
3) Guest Operating System: should be up to date and
secure from hackers
4) Data Encryption:should be done on all the data for
its safety.
C)Physical security:
1) Backup:Either a backup plan should be provided
automatically for each customer, or they can use the
plans provided elsewhere in the cloud.
2) Server Location:It should be at appropriate place. Room should have adequate space and
isolated. A
Cooling System and Fire Suppression System should
be installed there.
3) Firewall: Cloud Computing service providers should
provide a complete firewall solution to their clients.
Challenges:
A)No clear standard:Grid computing
uses various standards, but all grids are
not use same standards. Example all grid
operating system such as Linux, Apache,and My SQL are using WSRF,
WWW, SOAP and XML standards.
B)Distributed computing Vs Grid
computing: Grid computing involves
dynamic virtual organisation, resource
sharing and peer to peer computing. The
Grid intends to make access to
computing power, scientific data
repositories and experimental facilities
as easy as the Web makes access to
information. Same all facilities provide
the grid computing. So it is a challenge
for grid computing.
C)Lack of grid enabled software: The
software, which are enabled the grid
computing are less, It has limited
software on Grid. Much software has
not copyright issues and source code of
licence. It is need for more company
developing grid-enabled version, need
more developers on grid development
and need to develop open source
software.
D)Sharing Resources between Various
types of Services:Grid used for
sharing resource from various sites and
grid hosts. It handles a massive amount
of data as a grid platform. A lot of sites
and multiple servers gathered there it is
so complex infrastructure. It provides
difficulty for hardware resource sharing
within virtual organisation..

The organization of interrupted genes is often conserved between species. What does this mean
and what is an example of this conservation (diagram/explain)?
Solution
First we have know about interrupted genes is often conserved between species,the intricate
cellular machinery that converts genetic information into functional protein and RNA molecules
and the many ways in which gene expression is regulated by the cell,we discuss some of the
ways that genes and genomes have evolved over time to produce the vast diversity of modern-
day life forms on our planet uncovering an astonishing wealth of information about the family
relationships among organisms and evolutionary mechanisms,but the great revelation of the past
20 years has been the discovery that the actual nucleotide sequences of many genes are
sufficiently well conserved that homologous genes.
The recognition of sequence homology has become a major tool for inferring gene and protein
function thus it is often possible to predict the function of a gene in humans for which no
biochemical or genetic information is available simply by comparing its sequence to that of an
intensively studied gene in another organism.
Gene sequences are often far more tightly conserved than is overall genome structure as
discussed features of genome organization such as genome size,cells do not have specialized
mechanisms for creating changes in the structures of their genomes evolution depends instead on
accidents and mistakes.
Introns can be detected by the presence of additional regions when genes are compared with their
RNA products by restriction mapping or electron microscopy
The positions of introns are usually conserved when homologous genes are compared between
different organisms but the lengths of the corresponding introns may vary greatly..

selective pressure A kind of virus that preferentially and exclusively infects bacterial cells A
circular clearing within a lawn of growth; surrounding a disk or colony containing an
antimicrobial
Solution
The basic principle of Enrichment is that of selection. Enrichment culture provides favourable
growth conditions for the organism of intrest and unfavourable conditions for the competing
organisms. This technique can be used in many ways. for example, if we want to culture a
thermophile bacteria, incubate the sample at high temperature i.e., at above 55 degrees
centigrade because at that temperature, only the thermophilic bacteria can grow while this
temperature hampers the growth of other bacteria in the sample.
Likewise, enrichment culture may also contains antimicrobial agents to which the selective
organism is resistant hence the required organism\'s growth is facilitated hampering the growth
of other organisms which are not resistant to the antimicrobial agent.
Enrichment culture may also contains pesticides or N2 (used for selective growth of nitrogen
fixing bacteria) depending upon the type of microorganism selected.
Hence the Answer is a lawn of bacteria is prepared and filter discs containing antimicrobial
agents are applied..

Q1) Show what part of SSL that protects against the following attack.pdfarishmarketing21
Q1) Show what part of SSL that protects against the following attacks :-
a. Replay Attack: Earlier SSL handshake messages are replayed.
b. Man-in-the-Middle Attack: An attacker interposes during key exchange, acting as the client to
the server and as the server to the client.
c. IP Spoofing: Uses forged IP addresses to fool a host into accepting bogus data.
Q2) Describe the port forwarding operation. Using an example, describe the cases when it is very
useful, and the cases when it is very dangerous.
Solution
The secure socket layer (SSL) is a computer networking protocol that manages server
authentication, client authentication and encrypted communication between servers ant client
.
PROTACTION FROM REPLAY ATTACK-
The SSL itself is protected againsts replay attack using Medium Access Control ( MAC ). By
using MAC secret and the sequence number it ensures the communication integrity.
ssl handshake protocol
PROTECTION AGAINSTS MAN-IN-THE MIDDLE ATACK-
SSL is based on public/ private key cryptography. This basically means that there is a key pair.
The public key is used for encryption and secret key is used for decryption . A certificate is
basically a public key with a label identifying the owner. So when your browser connects to an
https server , the server will answer with its certificate. The browser checks if the certificate is
valid-
1: The owner information needs to match the server name that the user requested.
2: The certificate needs to be signed by a trusted certification authority.
if one of these condition is not met, the user is informed about the problem.
PROTECTION AGAINSTS IP SPOOFING-
An SSL certificate is specific to the particular domain for which it was created regardless of the
IP address of the doimain. So if a malicious entity want to attempt to redirect trafiic for a certain
website to their own malicious site through IP spoofing techniques. The fake site would not have
a SSL certificate that was accurately registerd to the real website.This can be varified through a
browser by viewing the certificate information and if the wrong address is shown, then the user
will know that they are not on the site they think they are on.Secure Socket Layer Architecture

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.

These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

1. What’s Love Got To Do With It?
The Evolution of Human Mating
By Meredith F. Small
Reviewed By Michael S. Kimmel
When Tina Turner first bitterly asked “What’s love got to do with it?” her voice was so drenched
with pain and regret, the listener knew better than to believe her.
Not so Meredith Small. A physical anthropologist whose main research has been on primate
mating behavior, Small joins a coterie of such writers as Robert Ardrey, Desmond Morris and
Lionel Tiger, who have sought to make evolutionary biology the foundation of studies of sexual
behavior.
In “What’s Love Got To Do With It,” Small argues that we’re genetically programmed to
experience sexual pleasure; hard-wired to search for young, attractive mates; driven to copulate
“Way down deep, underneath all the love and lust, underlying the attachment and intimacy, is
DNA pushing us along”
Like those male writers, she claims that our genetic predisposition toward reproductive success is
the driving force of our sex-seeking behavior. And like them, she assumes that sex is a constant,
universal and relatively unchanging experience. But unlike them, Small places no value on
judgments on the strategies that individuals may adopt to achieve that reproductive success.
Women, she argues, are as sexual as men; homosexuality is as “normal” as heterosexuality.
Small exposes many of her colleagues’ conclusions as based more on myth than on evolution.
Take, for example, the familiar canard that men are “naturally” predisposed toward promiscuity,
while women are “naturally” monogamous. Males’ prodigious sperm production, the argument
goes, means that it is in men’s interest to fertilize as many women as possible. But women
produce only one egg at a time, and gestation and child care take an extraordinarily long time,
which means that it is in their interest to mate with only one man for life.
Not only do such arguments assume what they are trying to explain, but their assumptions are
wrong to begin with. Sperm and eggs do not have little personalities, complete with ambitions
and motivations. What’s more, the evidence actually tilts the other way. Female humans are
among the only mammals who conceal estrus; that is, they do not go into “heat” when they are
2. sexually receptive. They are potentially sexually receptive all through their cycle. What’s more, a
woman has a clitoris, which “exists only to receive and give off sexual pleasure.” What could be
the evolutionary function of that?
Small argues that it is just as likely that women may be designed to maximize their reproductive
chances by promiscuity. If they have sex with a large number of male partners, they can ensure
that their offspring will have a significant number of men who believe that they are the father,
and who will, therefore, protect the baby and provide it with food.
“The ability to move from male to male certainly improves a female’s chance of finding the best
genes for her future offspring,” Small writes.
Males, by contrast, would prefer monogamy; otherwise they’ll run themselves ragged protecting
and providing for offspring that are not their own. Thus it would appear that the monogamous
couple is more likely invented by exhausted but powerful men that by romantic women intent
upon “happily ever after.”
Of course, neither of these versions is “true.” But Small’s feminist anthropology exposes the way
those earlier androcentric explanations simply projected current behavior back into a mythic past
and thereby created a seamless evolutionary path to the present. As such she provides a
refreshing rejoinder to the Darwinian boy’s club.
Unfortunately, Small doesn’t take this debunking to its logical next step: to question the entire
Darwinian model of sexual behavior. Although sex evolved originally “as a pleasurable response
to ensure that each of us is pushed to mate and pass on genes,” as she argues, we humans are also
uniquely designed -- blessed, really -- to experience sexual pleasure as distinct from
reproduction.
Even Small is stumped by homosexuality. “Here is a behavior, directly connected to
reproductive success, and yet by definition, designed not to pass on genes, so how could it
possibly have evolved as a mating strategy?” And while we’re at it, why is it in all human
societies?
You’d think those thorny problems would stop Small in her evolutionary tracks, but they bother
her very little. Such evidence means that sex as the possibility of more meanings than simple
gene transfer, however pleasurable that process might be.
It means that sex can also be about transcendence of everyday life, or just a momentary respite
from it, an expression of intimacy, or just plain fun. Sex can provide an emotional connection so
deep and nourishing that the rest of the world seems to evaporate. In short, love has something,
though perhaps not everything, to do with it after all.

3. Learning Objective: Compare and contrast two approaches of evolutionary psychology on
human behavior
Best practice to participate in the discussion boards is to read the articles and consider the
following questions. Then go to the discussion board and talk amongst yourselves; don't forget
to post a minimum of a paragraph and reply to a colleague.
1. Some evolutionary psychologists, such as David Buss, suggest that men are more promiscuous
than women. Man are hardwired for sex, wanting to have sex with as many women as possible.
This is an evolutionary advantage, which gives men the opportunity to impregnate as many
women as possible (i.e. to spread their seed). In addition, men prefer to have sex with women
that are younger and have an hourglass shape. Both youth and a curvy figure are evolutionary
signifiers of reproductive health. Buss also suggests that women are more selective in their
mating and dating preferences. While men have a tendency to want to sleep around, women are
choosier. Why? Because men have the ability to impregnate many women, while women can
only have one offspring at a time. It is evolutionarily advantageous for women to be picky about
their mates. What kind of mate to women prefer? They prefer mates with power and resources;
men who can provide for the survival of their offspring. For our early ancestors this meant a man
who could "bring home the bacon" now this means a man who brings home the money.
Feminist evolutionary psychologists think this is just ridiculous. This type of thinking just
portrays men and women as stereotypes.
2. Critics of the above theory demand: show me the physiological evidence. Evolutionary theory
is rooted in biology hence there must be physical evidence to substantiate a claim. Feminist
evolutionary psychologists say: It's not men who want sleep around, in fact, it is women who are
hard-wired to want to take on as many mates as possible. This is why society has spent so much
energy trying to regulate female sexuality. What is the evidence? One: only maternity is 100%.
Everyone knows for certain the identity of their mother, yet before the recent advent of testing,
paternity was never 100%. In a communal living situation, all the men in the tribe would have to
provide for a child because the possibility could be that child was their own. Two: women are
4. multi-orgasmic, while men only have one orgasm and then their brain releases a chemical which
causes them to fall asleep. As many know, women become active post-coitus. They want to talk
and cuddle, while men want to nap. The suggestion here is that while men are sleeping it off on
the bear skin rug, the women go to the next tent and have sex again with someone else. Finally,
women have an organ designed specifically for sexual pleasure: the clitoris. Men do not have
such an organ. The existence of the clitoris is a strong physiological indicator that supports the
above assertion. How can you explain the existence of the clitoris?

Solution
First theory of Buss supports that the men are more driven to have sex with many females
because they can impregnate many women at a time whereas one woman can have only one
developing egg in her womb at a time. Moreover it is obvious that women choose their mate
carefully so that he can take responsibility of the child and can earn well to take care of her and
the baby.
Second theory provides the physiological and biological evidence about women are more driven
towards mating than men because women are multiorgasmic and can go for another sex after one
completes.
Both these theories are trying to prove who is more sex driven. The women do not merely take
sex as a pleasure but they have to take care of the fetus inside womb and also of the new born for
many years after birth. So the price of sex is paid in larger extent by women. Men also take care
of the things financially but not at the risk of their own health and life. Whereas women are at the
risk of life while fetal development and birth.
