Define the types of ultrasound pressure waves Solution Ultrasound pressure waves that are widely used are --------- l. Longitudinal wave where the motion of the molecules in the medium is parallel to the direction of wave propagation. 2. Shear wave where particles move at right angles to the movement of the wave. In biological tissues it occurs only in the bones(solid tissue). Two more waves are also used and these are -------- 1. Surface wave which travels along the curved or flat surface of thick solids without influencing the bulk of medium below the surface. 2. Plate wave which are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the plate normal..

Solution
1. TCP protocol breaks the messages into fragments when packet size exceeds a certain
maximum value ,it is split into two or more fragments . It can be clearly explained as follows :
The IP layer injects a packet into the datalink layer and hopes for the best.
Each layer imposes some maximum size of packets ,due to various reasons
Suppose a large packet travels through a network whose MTU is samll,fragmentation is required.
Each fragment is transmitted as separate packet.
On the other hand ,An UDP application may wish to avoid fragmentation, because when the size
of the resulting datagram exceeds the link\'s MTU, the IP datagram is split across multiple IP
packets, which can lead to performance issues because if any fragment is lost, the entire
datagram is lost.
2.
3.TCP ensures all packets are processed in same original order .It happens as follows:
When an IP packet is sent by the source, it places a unique value in the identification field.
The IP packet is received at the router. The IP router notes that the maximum transmission unit
(MTU) of the network onto which the packet is to be forwarded is smaller than the size of the IP
packet.
IP divides the original IP payload into fragments that fit on the next network. Each fragment is
sent with its own IP header that contains:
The original identification field identifying all fragments that belong together.
The more fragments flag indicating that other fragments follow. The more fragments flag is not
set on the last fragment, because no other fragments follow it.
The fragments offset field indicating the position of the fragment relative to the original IP
payload.
When the fragments are received by IP at the remote host, they are identified by the
identification field as belonging together. The fragments offset field is then used to reassemble
the fragments into the original IP payload.
4. TCP is better for sending large amount of data. Reason is a UDP datagram is limited to 1500
bytes, so a message larger than that is split into smaller sections – or fragmented – and these
fragments may arrive out of order or be lost entirely as the UDP protocol does not acknowledge
or retry packets and on the other hand TCP splits messages into packets and ensures original
order of packets . See .

Explain TWO examples of fungal interactions with other species
Solution
Different types of fungi interact with surrounding species differently.
· In the plant-fungus interaction, some fungi are found to be mutualistic.
Thus, the fungal roots serve as a symbiotic relationship between both plants and fungi.
In contrast to these mutualistic fungi, there are also the parasitic fungi.
Another case is the saprotrophic fungi, which obtain their nutrients from dead organic matter,
such as leaf litter, dung, soil, dead animals etc.
Main outcome of the various interactions with fungi is disease. Fungi cause many serious plant
diseases. They cause diseases in animals, including human beings..

What is the relationship between continuous and analytic and differentiable for complex
function?
Solution
1. if a function is differentiable in an interval then it is continuous in that interval
ie differentiability => continuity but the converse need not be true
2 . If a function is differentiable in the given region then it is analytic in the region
If a function fails to be differentiable at a particular point in the region then it is not analytic.

Case Study: Urolithiasis
Case Presentation
Daniel, a thirty-two year old history instructor, was in his office preparing notes for an upcoming
seminar presentation when he was struck with a very sudden and intense pain in his side and
lower back. He remained at his desk, breathing deeply, and the pain began to recede. Five
minutes later, the pain was not as severe but Daniel was still uncomfortable and decided to call
his physician. Daniel described his symptoms to the doctor\'s receptionist and made an early
afternoon appointment. One of Daniel\'s colleagues drove Daniel to the doctor\'s office. While on
the way to his appointment, Daniel experienced another bout of severe pain and began to feel
nauseous. The pain seemed to be spreading into his lower abdomen and groin.
After asking Daniel a few questions about his symptoms, the doctor requested an abdominal x-
ray, several blood tests, and urinalysis. As Daniel supplied the urine sample he was disturbed to
notice that the urine had a pinkish cast. The physician returned and informed Daniel that he had a
kidney stone which, based on its size, should pass on its own within a day or so. The doctor told
Daniel that he should rest at home until the stone passed, drink at least 2-3 quarts of water each
day, and strain his urine in order to retrieve the stone for analysis. The doctor also gave Daniel a
prescription for pain medication.
Daniel passed the stone the following morning and brought it to the doctor\'s office. Analysis of
the stone\'s composition revealed that it was a calcium stone. Daniel\'s blood and urine tests had
also shown high calcium levels. Based on this, the doctor told Daniel to eat fewer foods
containing calcium or oxalate and provided Daniel with a list of foods to limit. He also told
Daniel to continue to drink at least two quarts of water each day.
Case Description
The presence of kidney stones, or urinary caliculi, in the urinary tract is called urolithiasis. These
stones form from materials that are excreted by the kidneys. Normally these excreted materials
stay dissolved in urine, but in some individuals they form precipitates that can develop into
kidney stones. Kidney stones can form from several different substances. Kidney stone analysis,
blood tests, and urinalysis all assist a physician in determining how best to avoid the
development of future stones. Calcium stones are most common, comprising between 80 and 90
percent of urinary caliculi. The calcium stones are formed from calcium phosphate or calcium
oxalate, and persons predisposed to developing these stones are often instructed to decrease
calcium and oxalate intake. In some cases, medications are prescribed that decrease calcium
excretion by the kidneys or alter urine pH, a factor in kidney stone formation.
The pain associated with the blockage of the urinary tract by a kidney stone is called renal colic
and can be very intense. Treatment depends primarily on the size of the stone. Stones smaller
than 5 mm .

What are the main motives for establishing an international joint ve.pdf
What are the main motives for establishing an international joint venture? Illustrate your answer
by drawing upon the case study of Renault & Nissan.
Solution
Defining the ‘motive’ of international joint venture
The study of motives of international joint ventures in international business and marketing
literature is consistent and substantial (Hyder, 1999; Tatoglu, 2000; Banai et al 1999; Fahy et al
1998; Tatoglu and Glaister 1998; Wong 1998). Motives of IJV formation have been assessed in
different country contexts (for example UK, Sweden, Turkey, Hungary, Hong Kong, Russia etc).
The examination of IJV literature however suggests that IJV studies suffer from an imperfect
understanding of the term ‘motive’. None of the studies examined in this paper has made any
attempt to define the term ‘motive’. It appears that researchers and authors in prior studies have
assumed that ‘motive’ is a well-understood term by the academic audience including researchers,
readers and respondents. The available evidence of multiple interpretations in different studies
however indicated subjective and fractured understanding of this key concept.
The lack of definition of motive is a critical oversight in IJV research effort. It has contributed to
the possibility of multiple interpretations. It is argued that the absence of a consistent
interpretation and definition of the term motive has been a key contributory factor to the slow
progress of research on IJV motives. A lack of universally accepted definition has led to
interpretation inconsistencies in different IJV studies. While the precise understanding of
‘motive’ as a fundamental concept is essential in any investigation of IJV motives, it has
received little or no attention in earlier literature. It is argued that the comprehensive definition of
‘motive’ is central to bringing about a balanced understanding to this area of research
EXISTING INTERPRETATIONS:
The dominant interpretation of motive in most studies borders the notion of ‘reasons’ of
choosing IJV governance structure. The seminal work of Tomlinson (1970, 192) sets the
tradition of interpreting motives as reasons for example ‘favorable past association’ was reported
as the single most important reason followed by ‘facilities’, ‘resources’, and ‘partner status’. In
other studies, motive is also interpreted in slightly different but related manner. Interpretation of
Hyder and Ghauri (1989) and Hyder (1999) suggest the notion of benefits rather than the
dominant interpretation of ‘reason’ implied by the term motive. Subsequent studies however by
Glaister (1996), Fahy et al (1998), Wong (1998), Tatoglu (2000) seem to continue with the
interpretation of Tomlinson although without any explicit acknowledgement. The problem of
multiple interpretations is further exacerbated by inconsistent and often vaguely stated
theoretical approaches of IJV studies. The following section sets out to define the concept of
‘motive’ from a resource-based perspective.

9 & 10
9. The study of behavioral finance has best helped explain which of the following investor
behav- iors? (a) Investors are often unable to short-sell unfavorable stocks. (b) Investors often
create undiversified portfolios (c) Investors tend to sell their losing stocks and retain stocks that
have capital gains. (d) Investors are generally too slow to update their beliefs in the face of new
evidence 10. Briefly discuss some of the important findings of behavioral finance studies.
Solution
9) d is correct
Behavioral finance has been very helpful in explaining that inveatinv are too slow to update their
beliefs in the face of new evidences.
10) Behavioral finance has focused on two crucial areas and they are attitude towards risk and
beliefs about probability. It tells us that security mispricing can result from the investor\'s attitude
towards risk and how they asses probability. It deals with behaviour of investors at the time of
capital gain and capital loss. It tells us that investors are either risk averse or risk loving that is
they do not behave rationally..
Will Chinas economic success continue into the foreseeable future.pdf
Will China\'s economic success continue into the foreseeable future? If not, what might derail it?
Solution
No chinese economics success may not be continue into the foreseeable future because of the
following reasons.
1) From the past 25 yeras china is having large number of youth who are aged between 21-35
.Now the Youth population is slowing decling and the people who are older are increasing.
2) China is having a big threat in the form of India. India is trying to emerge as a developed and
is moving its steps in that way. It is also developing in every aspect and growth rate is also high.
India and China both are most populous countries in the world. They both are trying to emerge as
a super power.
3) Chinese market is decling as people are having a negativity that there goods are of low quality
and the manufacturing industries are trying to maintain distance from them.
4) All the World knows china manipulates its currency for exporting there goods.
5) All the worlds are negative towards due to various political reasons.
6) Now as it is the time globalization China is still a closed economy which is not good for that
country.
So all these factors will effect china which will have impact on its economy and its growth..

What happens to the income shares of capital and labor in this economy? No math is necessary
but it may help to see the answer if you pretend that capital increased from 1000 to 1500 while
the amount of labor stayed the same. f) In the production function for Stock Ville briefly explain
what the \"2\" represents.
Solution
a) Marginal product of labor is the derivative of production function wrt labor and Marginal
product of capital is the derivative of production function wrt capital.
MPL = 2x0.8xK^(0.2)xL^(0.8-1) = 1.6(K/L)^0.2. Similarly, MPK = 0.4(L/K)^0.8
b) We see that MPK = 0.4(L/K)^0.8. This implies that for any values of K and L > or = 0, MPK
is positive. Now find the derivative of MPK with respect to K.
d(MPK)/dK = 0.4*(-0.8)*(L^0.8)*(K^-1.8). = -0.32(L^0.8)*(K^-1.8)
For any values of K and L > or = 0, MPK is now negative. This shows that as capital rises MPK
falls. This is basic postulate of diminshing marginal returns to capital
c) At L = 200 and K = 1000, MPK is 0.4*(200/1000)^0.8 = 0.1104. For 1000 units of capital,
payment made to capital is 110.4. At 200 units of labor, MPL is 1.6*(1000/200)^0.2 = 2.2076.
For 200 units of labor, payment made to labor is 2.2076*200 = 441.52.
d) At the current rate, MPL > MPK. Adding more capital will reduce the rental price of capital
because its supply is increased and capital owners will be willing to accpet a lower rate as well.
Real wage will increase as less labor is used and so MPL will increase.
e) Income share of capital and income share of labor both will increase if labor employed is
unchanged. This is because rental rate of capital has reduced due to low MPK while K is
increased. MPL has K in the denominator so a rise in K will increase MPL. Labor share in
income rises essentially. Capital share rises because K rises even though MPK falls
f) 2 is the technology parameter that indicates how much of the production is increased due to
technology..
What is the pre-order traversal sequence for the above treeSolut.pdf
What is the pre-order traversal sequence for the above tree?
Solution
Pre-order means exploring the roots before inspecting the leaves..
Consider the below example for ease:
- ROOT
- A
- B
- C
- D
- E
- F
- G
struct Node{
int data;
Node *left, *right;
};
void preOrderPrint(Node *root)
{
print(root->name);
if (root->left != NULL) preOrderPrint(root->left);
if (root->right != NULL) preOrderPrint(root->right);.
Show that the class P, viewed as a set of languages is closed under c.pdf
Show that the class P, viewed as a set of languages is closed under complement.
Solution
For any P-language L, let M be the TM that decides it in polynomial time. We build a TM M’
that decides the complement of L in polynomial time:
M’= “On input :
1. Run M on w.
2. If M accepts, reject. If it rejects, accept.
M decides the complement of L. So that M runs in polynomial time, M’ also runs in polynomial
time..

Related to Making the Connection] In the court case over whether anyone could use Doyle\'s
character of Sherlock Holmes without paying a fee, Judge Posner argued that the first Sherlock
Holmes story was written in 1887, so allowing the author\'s descendants to continue to claim a
copyright to the character raised the possibility of \"perpetual, or at least nearly perpetual,
copyright.\" The judge also noted that the U.S. Constitution had only given Congress the
authority to grant copyright for a limited time. Source: Leslie S. Kling v. Conan Doyle Estate,
Ltd (7th Cir. 2014), media.ca7.uscourts.gov.
Allowing an author and his or her descendants to have a copyright forever on a book or character
has disadvantages including:
A. lost revenue from competing authors.
B. the reduction of new books, movies, and television series based on existing characters that
results from copyright periods.
C. the problems associated with terminating the copyright after so many years have passed.
D. the inability to track the heirs and descendents to pay the copyright.
Allowing an author and his or her descendants to have a copyright forever on a book or character
has advantages including:
A. a more fully developed cast of characters that can be used in future books.
B. incentives that it provides for writers to write books that they might not have written.
C. revenue that generates tax payments.
D. decreased payments to some authors using other authors\' characters to produce new books.

PROGRAM 2 – Fraction Class Problem For this programming as.pdf
PROGRAM 2 – Fraction Class
Problem For this programming assignment, you are to implement the Fraction class design
given below (and discussed in class). You are also to develop an appropriate test driver that
thoroughly tests the class.
Fraction Class Design Implement the following class design. Make sure to use implement the
methods to have the same names as given below, with the same number and types of parameters.
public class Fraction {
private int numer;
private int denom;
// alternate constructor
public Fraction(int numer, int denom)
throws InvalidDenominatorException {
}
// copy constructor
public Fraction(Fraction otherFrac) {
}
// getters
public int getNumer() {
}
public int getDenom() {
}
// standard methods
public String toString() {
}
public boolean equals(Fraction rFrac) {
}
// fraction operators
public Fraction add(Fraction rFrac) {
}
public Fraction sub(Fraction rFrac) {
}
public Fraction mult(Fraction rFrac) {
}
public Fraction div(Fraction rFrac) {
}
public boolean isSimplestForm() {
}
public Fraction reduce() {
}
public boolean properFrac() {
}
public Fraction abs() {
}
public boolean lessThan(Fraction rFrac) {
}
public boolean greaterThan(Fraction rFrac) {
}
public double convertToDecimal() {
}
public Fraction invert() {
}
}
Note that objects of type Fraction are immutable. Also, the alternate constructor throws an
InvalidDenominatorException if passed a denominator value of 0. This exception type is not
predefined in Java, so you must define it as follow as another class in your Java project files:
public class InvalidDenominatorException extends RuntimeException { } // nothing to
implement
This creates an exception of type RuntimeException. RuntimeExceptions do not need to be
caught when thrown. However, your test driver should have the code for catching this exception
where appropriate.
For example, if your test driver excutes the following,
Fraction frac1 = new Fraction(1,2);
then there is no need to catch the possible exception, since it is clear that the denominator is not
0. However, if the value are input by the user, then there is a chance that a denominator vaue of 0
could be entered, and therefore the code for catching the possible exception is needed,
int numer, denom;
Fraction frac1;
Scanner input = new Scanner(System.in);
Boolean valid_input = false;
while (!valid_input) try {
System.out.print(“Enter numerator denominator: “);
numer = input.nextInt();
denom = input.nextInt();
frac1 = new Fraction(numer,denom);
valid_input = true;
}
catch (InvalidDenominatorException e) {
System.out.println(“Denominator of Zero found – Please reenter”);
}
catch (InputMismatchException e) {
System.out.println(“Non-digit character found – Please reenter”);
} etc.
Considerations
Makes sure the equals method returns true for any two fractions that are arithmetically equal.
Make sure that the equals, lessThan and greaterThan methods do not alter the values of the
fractions being compared. You may consider the use of private methods .
Presence on the Web and Internet are critical components of just abo.pdf
Presence on the Web and Internet are critical components of just about any business, large or
small. However, having a website presence can increase the security risks and threats to which
an organization is subject.
What roles do security analysts play in preventing Web server, application, and database attacks?
How do these roles differ in different types of organizations?
Solution
the role of the security analyst while preventing web server,appliaction and database attacks:
1)in perpestive of webserver and application: he will monitor the logs and he may also use log
monitoring tools .here he will check what are the ip\'s accessing we pages. and also check
whether there are any intruders.
the main thing he will check about:
i)SQL injection
ii)brute drive protection
iii)malware
iv)cross website scripting
v)denial of service
vi)buffer overflow
in perpesctive of database :
here analyst will check in the follwoing areas
i)Excessive previlages
ii)database injections
iii)malware
iv)data loss
v)un managed sensitive data
these roles may differ in different organizations
=> some organizations may have as security analayst ,and some of the organization may
categorize them according to their requirement .for example ,some organization may have
security analyst for only webserver and applications, and database security analyst
=>if the organization in dealing big in databases related issues the he may categorize them
according to this requriement . so this type of organization requires database security analyst
=>if an organization is dealing with apllication related issues and database too then they need
them both...
1.1 How can globalization and international economic integration be .pdf
1.1 How can globalization and international economic integration be measured?
Solution
Globalisation refers to the integration of world economies. there are free flows of goods and
services, capital and human resources. Usually, some economists do not count the human
resource free flow as part of globalisation. following factors are used to measure globalisation
and international economic integration:
Though we can draw general idea if we are moving towards the globalisation or retreating, but
we can not measure globalisation in precise numerical term..

SpreadsheetWriter.java
Can you please help me the JAVA program? Let\'s write a program that will produce a file that
can be opened by Excel or LibreOffice Calc. Go to Getting Started and look up the grading
weights used for this course. As an example, we\'ll use the following table, but you should use
the values you find in Getting Started. Write a class SSRow. Objects of this class should keep
track of String name, int score, int weight, String calc. SSRow also has a to String method that
returns this data in order, separated by commas. name + \", \"+ score +\", \"+ weight +\", \"+ calc
Further design of the SSRow class is left to you. Add what you need, but don\'t get carried away.
Write a class SSWriter that has a main method. For each of the grading categories (Lab. Reading
Quizzes. Group Work. Midterm. Project. Final. Instructor Discretion). query the user for a score,
and create the following SSRow objects: \"Lab\", : 20. \"=B1Times C1/100\" \"Reading
Quizzes\". , 10, \"=B2TimesC2/100\" \"Group Work\". , 10, \"=B3 Times C3/100\" \"Midterm\".
. 20, \"=B4 Times C4/100\" \"Project\", . 15, \"=B5 Times C5/100\" \"Final\", . 20, \"=B6 Times
C6/100\" \"Instructor Discretion\". , 5, \"=B7 Times C7/100\" Open a file for output with a file
type of csv (say MyGrades.csv, for example). Write the to String value for each SSRow to the
file. Finally, write a row \"average\".=(D1+D2+D3+D4+D5+D6+D7) Open MyGrades.csv
with Excel or LibreOffice Calc.

Note I only need the last 3 sub-questions ( e, f and g) 3. Firew.pdf
Note: I only need the last 3 sub-questions ( e, f and g) 3. Firewall Design (55pts) Design a
firewall for your Linux machine using the iptables packet filtering mod- It is likely that iptables
came pre-installed with the Linux distribution you are using. In the event you are using an old
version of the Linux kernel, you may need to upgrade it for iptables to work. Your homework
consists of writing iptables rules to do the following: (a) Place no restriction on outbound
packets. (b) Allow for ssH access (port 22) to your machine from only the fiu.edu domain. (c)
Assuming you are running an HTTPD server on your machine that can make available your
entire horne directory to the outside world, write a rule that allows only a single IP address in the
internet to access your machine for the HTTP service. (d) Permit Auth/Ident (port 113) that is
used by some services like SMTP and (e) Aocept the ICMP Echo requests (as used by ping)
ooming from the outside. Respond back with TcP RST or ICMP unreachable for incoming
requests blocked ports. (g) Block all input packats from the enn.com domain and respond back
with destination unreachable error message for all incoming SYN packets from the cnn.com
domain.
Solution
(e) Echo Request:
Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the
target host and waiting for an ICMP echo reply. It measures the round-trip time from
transmission to reception, reporting errors and packet loss.
Ping is a computer network administration software utility used to test the reachability of a host
on an Internet Protocol (IP) network.
Packet InterNet Gopher, is a computer network administration utility used to test the reachability
of a host on an Internet Protocol (IP) network and to measure the total round-trip time for
messages sent from the originating host to a destination computer and back.
Ping operates by sending Internet Control Message Protocol (ICMP) Echo Request packets to the
target host and waiting for an ICMP Echo Reply. The program reports errors, packet loss, and a
statistical summary of the results, typically including the minimum, maximum, the mean round-
trip times, and standard deviation of the mean.
The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol
suite. It is used by network devices, like routers, to send error messages and operational
information indicating, for example, that a requested service is not available or that a host or
router could not be reached. ICMP differs from transport protocols such as TCPand UDP in that
it is not typically used to exchange data between systems, nor is it regularly employed by end-
user network applications (with the exception of some diagnostic tools like ping and traceroute).
The Internet Control Message Protocol (ICMP) has many messages that are identified by a
“type” field. You need to use 0 and 8 ICMP code types.
=> Zero (0) is for echo-reply
=> Eight (8) is for echo-request.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

What are the main motives for establishing an international joint ve.pdf
What are the main motives for establishing an international joint venture? Illustrate your answer
by drawing upon the case study of Renault & Nissan.
Solution
Defining the ‘motive’ of international joint venture
The study of motives of international joint ventures in international business and marketing
literature is consistent and substantial (Hyder, 1999; Tatoglu, 2000; Banai et al 1999; Fahy et al
1998; Tatoglu and Glaister 1998; Wong 1998). Motives of IJV formation have been assessed in
different country contexts (for example UK, Sweden, Turkey, Hungary, Hong Kong, Russia etc).
The examination of IJV literature however suggests that IJV studies suffer from an imperfect
understanding of the term ‘motive’. None of the studies examined in this paper has made any
attempt to define the term ‘motive’. It appears that researchers and authors in prior studies have
assumed that ‘motive’ is a well-understood term by the academic audience including researchers,
readers and respondents. The available evidence of multiple interpretations in different studies
however indicated subjective and fractured understanding of this key concept.
The lack of definition of motive is a critical oversight in IJV research effort. It has contributed to
the possibility of multiple interpretations. It is argued that the absence of a consistent
interpretation and definition of the term motive has been a key contributory factor to the slow
progress of research on IJV motives. A lack of universally accepted definition has led to
interpretation inconsistencies in different IJV studies. While the precise understanding of
‘motive’ as a fundamental concept is essential in any investigation of IJV motives, it has
received little or no attention in earlier literature. It is argued that the comprehensive definition of
‘motive’ is central to bringing about a balanced understanding to this area of research
EXISTING INTERPRETATIONS:
The dominant interpretation of motive in most studies borders the notion of ‘reasons’ of
choosing IJV governance structure. The seminal work of Tomlinson (1970, 192) sets the
tradition of interpreting motives as reasons for example ‘favorable past association’ was reported
as the single most important reason followed by ‘facilities’, ‘resources’, and ‘partner status’. In
other studies, motive is also interpreted in slightly different but related manner. Interpretation of
Hyder and Ghauri (1989) and Hyder (1999) suggest the notion of benefits rather than the
dominant interpretation of ‘reason’ implied by the term motive. Subsequent studies however by
Glaister (1996), Fahy et al (1998), Wong (1998), Tatoglu (2000) seem to continue with the
interpretation of Tomlinson although without any explicit acknowledgement. The problem of
multiple interpretations is further exacerbated by inconsistent and often vaguely stated
theoretical approaches of IJV studies. The following section sets out to define the concept of
‘motive’ from a resource-based perspective.

9. The study of behavioral finance has best helped explain which of the following investor
behav- iors? (a) Investors are often unable to short-sell unfavorable stocks. (b) Investors often
create undiversified portfolios (c) Investors tend to sell their losing stocks and retain stocks that
have capital gains. (d) Investors are generally too slow to update their beliefs in the face of new
evidence 10. Briefly discuss some of the important findings of behavioral finance studies.
Solution
9) d is correct
Behavioral finance has been very helpful in explaining that inveatinv are too slow to update their
beliefs in the face of new evidences.
10) Behavioral finance has focused on two crucial areas and they are attitude towards risk and
beliefs about probability. It tells us that security mispricing can result from the investor\'s attitude
towards risk and how they asses probability. It deals with behaviour of investors at the time of
capital gain and capital loss. It tells us that investors are either risk averse or risk loving that is
they do not behave rationally..
Will Chinas economic success continue into the foreseeable future.pdf
Will China\'s economic success continue into the foreseeable future? If not, what might derail it?
Solution
No chinese economics success may not be continue into the foreseeable future because of the
following reasons.
1) From the past 25 yeras china is having large number of youth who are aged between 21-35
.Now the Youth population is slowing decling and the people who are older are increasing.
2) China is having a big threat in the form of India. India is trying to emerge as a developed and
is moving its steps in that way. It is also developing in every aspect and growth rate is also high.
India and China both are most populous countries in the world. They both are trying to emerge as
a super power.
3) Chinese market is decling as people are having a negativity that there goods are of low quality
and the manufacturing industries are trying to maintain distance from them.
4) All the World knows china manipulates its currency for exporting there goods.
5) All the worlds are negative towards due to various political reasons.
6) Now as it is the time globalization China is still a closed economy which is not good for that
country.
So all these factors will effect china which will have impact on its economy and its growth..
Which of the following ions would exhibit the greatest conductivity.pdf
Which of the following ions would exhibit the greatest conductivity? Explain your answers.
a) Li+ or Cs+
b) Mg2+ or Al3+
Solution
A. The conductivity of Li+ is greater than Cs+. This is because, in general, smaller ions have
greater conductivity as there is less resistance as they move through the solution.
B. Al3+ has greater conductivity as Al3+ is smaller in size..
Which fault-tolerant-like system can back up media in much the same .pdf
Which fault-tolerant-like system can back up media in much the same way as disk striping?
A. RAID
B. RAIT
C. JBOD
D. MAID
Solution
B. Redundant Array of Inexpensive Tape (RAIT) is used to back up systems by means of a tape
array that stripes the data across the tape. Answer A is incorrect because RAID is not typically
used for backup. Answer C is incorrect because JBOD (Just a Bunch of Disks) offers no backup
or fault tolerance. Answer D is incorrect because MAID (Massive Array of Inactive Disks) is not
a type of tape backup.

4) Production in the country of StockVille can be characterized by th.pdf
4) Production in the country of StockVille can be characterized by the following function: Y=
2K0.20.8 and that Stockville initially has 200 units of labor and 1000 units of capital. a) b) c) d)
Calculate the marginal product of labor and marginal product of capital for StockVille. Show
with calculus that the production function exhibits diminishing returns to capital. Calculate the
total payments to labor and capital in StockVille. Suppose that in Stock Ville there is a large
increase in investment that adds a lot more capital to the economy. What happens to the rental
rate of capital and real wage rate in StockVille? Briefly explain 2 e Aain suppose that in
StockVille there is a large increase in investment that adds a lot more capital to the economy.
What happens to the income shares of capital and labor in this economy? No math is necessary
but it may help to see the answer if you pretend that capital increased from 1000 to 1500 while
the amount of labor stayed the same. f) In the production function for Stock Ville briefly explain
what the \"2\" represents.
Solution
a) Marginal product of labor is the derivative of production function wrt labor and Marginal
product of capital is the derivative of production function wrt capital.
MPL = 2x0.8xK^(0.2)xL^(0.8-1) = 1.6(K/L)^0.2. Similarly, MPK = 0.4(L/K)^0.8
b) We see that MPK = 0.4(L/K)^0.8. This implies that for any values of K and L > or = 0, MPK
is positive. Now find the derivative of MPK with respect to K.
d(MPK)/dK = 0.4*(-0.8)*(L^0.8)*(K^-1.8). = -0.32(L^0.8)*(K^-1.8)
For any values of K and L > or = 0, MPK is now negative. This shows that as capital rises MPK
falls. This is basic postulate of diminshing marginal returns to capital
c) At L = 200 and K = 1000, MPK is 0.4*(200/1000)^0.8 = 0.1104. For 1000 units of capital,
payment made to capital is 110.4. At 200 units of labor, MPL is 1.6*(1000/200)^0.2 = 2.2076.
For 200 units of labor, payment made to labor is 2.2076*200 = 441.52.
d) At the current rate, MPL > MPK. Adding more capital will reduce the rental price of capital
because its supply is increased and capital owners will be willing to accpet a lower rate as well.
Real wage will increase as less labor is used and so MPL will increase.
e) Income share of capital and income share of labor both will increase if labor employed is
unchanged. This is because rental rate of capital has reduced due to low MPK while K is
increased. MPL has K in the denominator so a rise in K will increase MPL. Labor share in
income rises essentially. Capital share rises because K rises even though MPK falls
f) 2 is the technology parameter that indicates how much of the production is increased due to
technology..

if (root->right != NULL) preOrderPrint(root->right);.
Show that the class P, viewed as a set of languages is closed under c.pdf
Show that the class P, viewed as a set of languages is closed under complement.
Solution
For any P-language L, let M be the TM that decides it in polynomial time. We build a TM M’
that decides the complement of L in polynomial time:
M’= “On input :
1. Run M on w.
2. If M accepts, reject. If it rejects, accept.
M decides the complement of L. So that M runs in polynomial time, M’ also runs in polynomial
time..
Related to Making the Connection] In the court case over whether any.pdf
Related to Making the Connection] In the court case over whether anyone could use Doyle\'s
character of Sherlock Holmes without paying a fee, Judge Posner argued that the first Sherlock
Holmes story was written in 1887, so allowing the author\'s descendants to continue to claim a
copyright to the character raised the possibility of \"perpetual, or at least nearly perpetual,
copyright.\" The judge also noted that the U.S. Constitution had only given Congress the
authority to grant copyright for a limited time. Source: Leslie S. Kling v. Conan Doyle Estate,
Ltd (7th Cir. 2014), media.ca7.uscourts.gov.
Allowing an author and his or her descendants to have a copyright forever on a book or character
has disadvantages including:
A. lost revenue from competing authors.
B. the reduction of new books, movies, and television series based on existing characters that
results from copyright periods.
C. the problems associated with terminating the copyright after so many years have passed.
D. the inability to track the heirs and descendents to pay the copyright.
Allowing an author and his or her descendants to have a copyright forever on a book or character
has advantages including:
A. a more fully developed cast of characters that can be used in future books.
B. incentives that it provides for writers to write books that they might not have written.
C. revenue that generates tax payments.
D. decreased payments to some authors using other authors\' characters to produce new books.
Solution
Allowing an author and his or her descendants to have a copyright forever on a book or charcter
has disadvantages including A) lost revenue from competing authors
Allowing an author and his or her descendants to have a copyright forever on a book or character

PROGRAM 2 – Fraction Class Problem For this programming as.pdf
PROGRAM 2 – Fraction Class
Problem For this programming assignment, you are to implement the Fraction class design
given below (and discussed in class). You are also to develop an appropriate test driver that
thoroughly tests the class.
Fraction Class Design Implement the following class design. Make sure to use implement the
methods to have the same names as given below, with the same number and types of parameters.
public class Fraction {
private int numer;
private int denom;
// alternate constructor
public Fraction(int numer, int denom)
throws InvalidDenominatorException {
}
// copy constructor
public Fraction(Fraction otherFrac) {
}
// getters
public int getNumer() {
}
public int getDenom() {
}
// standard methods
public String toString() {
}
public boolean equals(Fraction rFrac) {
}
// fraction operators
public Fraction add(Fraction rFrac) {
}
public Fraction sub(Fraction rFrac) {
}
public Fraction mult(Fraction rFrac) {
}
public Fraction div(Fraction rFrac) {
}
public boolean isSimplestForm() {
}
public Fraction reduce() {
}
public boolean properFrac() {
}
public Fraction abs() {
}
public boolean lessThan(Fraction rFrac) {
}
public boolean greaterThan(Fraction rFrac) {
}
public double convertToDecimal() {
}
public Fraction invert() {
}
}
Note that objects of type Fraction are immutable. Also, the alternate constructor throws an
InvalidDenominatorException if passed a denominator value of 0. This exception type is not
predefined in Java, so you must define it as follow as another class in your Java project files:
public class InvalidDenominatorException extends RuntimeException { } // nothing to
implement
This creates an exception of type RuntimeException. RuntimeExceptions do not need to be
caught when thrown. However, your test driver should have the code for catching this exception
where appropriate.
For example, if your test driver excutes the following,
Fraction frac1 = new Fraction(1,2);
then there is no need to catch the possible exception, since it is clear that the denominator is not
0. However, if the value are input by the user, then there is a chance that a denominator vaue of 0
could be entered, and therefore the code for catching the possible exception is needed,
int numer, denom;
Fraction frac1;
Scanner input = new Scanner(System.in);
Boolean valid_input = false;
while (!valid_input) try {
System.out.print(“Enter numerator denominator: “);
numer = input.nextInt();
denom = input.nextInt();
frac1 = new Fraction(numer,denom);
valid_input = true;
}
catch (InvalidDenominatorException e) {
System.out.println(“Denominator of Zero found – Please reenter”);
}
catch (InputMismatchException e) {
System.out.println(“Non-digit character found – Please reenter”);
} etc.
Considerations
Makes sure the equals method returns true for any two fractions that are arithmetically equal.
Make sure that the equals, lessThan and greaterThan methods do not alter the values of the
fractions being compared. You may consider the use of private methods .
Presence on the Web and Internet are critical components of just abo.pdf
Presence on the Web and Internet are critical components of just about any business, large or
small. However, having a website presence can increase the security risks and threats to which
an organization is subject.
What roles do security analysts play in preventing Web server, application, and database attacks?
How do these roles differ in different types of organizations?
Solution
the role of the security analyst while preventing web server,appliaction and database attacks:
1)in perpestive of webserver and application: he will monitor the logs and he may also use log
monitoring tools .here he will check what are the ip\'s accessing we pages. and also check
whether there are any intruders.
the main thing he will check about:
i)SQL injection
ii)brute drive protection
iii)malware
iv)cross website scripting
v)denial of service
vi)buffer overflow
in perpesctive of database :
here analyst will check in the follwoing areas
i)Excessive previlages
ii)database injections
iii)malware
iv)data loss
v)un managed sensitive data
these roles may differ in different organizations
=> some organizations may have as security analayst ,and some of the organization may
categorize them according to their requirement .for example ,some organization may have
security analyst for only webserver and applications, and database security analyst
=>if the organization in dealing big in databases related issues the he may categorize them
according to this requriement . so this type of organization requires database security analyst
=>if an organization is dealing with apllication related issues and database too then they need
them both...
1.1 How can globalization and international economic integration be .pdf
1.1 How can globalization and international economic integration be measured?
Solution
Globalisation refers to the integration of world economies. there are free flows of goods and
services, capital and human resources. Usually, some economists do not count the human
resource free flow as part of globalisation. following factors are used to measure globalisation
and international economic integration:
Though we can draw general idea if we are moving towards the globalisation or retreating, but
we can not measure globalisation in precise numerical term..

SpreadsheetWriter.java
Can you please help me the JAVA program? Let\'s write a program that will produce a file that
can be opened by Excel or LibreOffice Calc. Go to Getting Started and look up the grading
weights used for this course. As an example, we\'ll use the following table, but you should use
the values you find in Getting Started. Write a class SSRow. Objects of this class should keep
track of String name, int score, int weight, String calc. SSRow also has a to String method that
returns this data in order, separated by commas. name + \", \"+ score +\", \"+ weight +\", \"+ calc
Further design of the SSRow class is left to you. Add what you need, but don\'t get carried away.
Write a class SSWriter that has a main method. For each of the grading categories (Lab. Reading
Quizzes. Group Work. Midterm. Project. Final. Instructor Discretion). query the user for a score,
and create the following SSRow objects: \"Lab\", : 20. \"=B1Times C1/100\" \"Reading
Quizzes\". , 10, \"=B2TimesC2/100\" \"Group Work\". , 10, \"=B3 Times C3/100\" \"Midterm\".

C6/100\" \"Instructor Discretion\". , 5, \"=B7 Times C7/100\" Open a file for output with a file
type of csv (say MyGrades.csv, for example). Write the to String value for each SSRow to the
file. Finally, write a row \"average\".=(D1+D2+D3+D4+D5+D6+D7) Open MyGrades.csv
with Excel or LibreOffice Calc.

Note I only need the last 3 sub-questions ( e, f and g) 3. Firew.pdf
Note: I only need the last 3 sub-questions ( e, f and g) 3. Firewall Design (55pts) Design a
firewall for your Linux machine using the iptables packet filtering mod- It is likely that iptables
came pre-installed with the Linux distribution you are using. In the event you are using an old
version of the Linux kernel, you may need to upgrade it for iptables to work. Your homework
consists of writing iptables rules to do the following: (a) Place no restriction on outbound
packets. (b) Allow for ssH access (port 22) to your machine from only the fiu.edu domain. (c)
Assuming you are running an HTTPD server on your machine that can make available your
entire horne directory to the outside world, write a rule that allows only a single IP address in the
internet to access your machine for the HTTP service. (d) Permit Auth/Ident (port 113) that is
used by some services like SMTP and (e) Aocept the ICMP Echo requests (as used by ping)
ooming from the outside. Respond back with TcP RST or ICMP unreachable for incoming
requests blocked ports. (g) Block all input packats from the enn.com domain and respond back
with destination unreachable error message for all incoming SYN packets from the cnn.com
domain.
Solution
(e) Echo Request:
Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the
target host and waiting for an ICMP echo reply. It measures the round-trip time from
transmission to reception, reporting errors and packet loss.
Ping is a computer network administration software utility used to test the reachability of a host
on an Internet Protocol (IP) network.
Packet InterNet Gopher, is a computer network administration utility used to test the reachability
of a host on an Internet Protocol (IP) network and to measure the total round-trip time for
messages sent from the originating host to a destination computer and back.
Ping operates by sending Internet Control Message Protocol (ICMP) Echo Request packets to the
target host and waiting for an ICMP Echo Reply. The program reports errors, packet loss, and a
statistical summary of the results, typically including the minimum, maximum, the mean round-
trip times, and standard deviation of the mean.
The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol
suite. It is used by network devices, like routers, to send error messages and operational
information indicating, for example, that a requested service is not available or that a host or
router could not be reached. ICMP differs from transport protocols such as TCPand UDP in that
it is not typically used to exchange data between systems, nor is it regularly employed by end-
user network applications (with the exception of some diagnostic tools like ping and traceroute).
The Internet Control Message Protocol (ICMP) has many messages that are identified by a
“type” field. You need to use 0 and 8 ICMP code types.
=> Zero (0) is for echo-reply

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Define the types of ultrasound pressure wavesSolutionUltrasoun.pdf
- 1. Define the types of ultrasound pressure waves Solution Ultrasound pressure waves that are widely used are --------- l. Longitudinal wave where the motion of the molecules in the medium is parallel to the direction of wave propagation. 2. Shear wave where particles move at right angles to the movement of the wave. In biological tissues it occurs only in the bones(solid tissue). Two more waves are also used and these are -------- 1. Surface wave which travels along the curved or flat surface of thick solids without influencing the bulk of medium below the surface. 2. Plate wave which are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the plate normal.
