Here are the key advantages of meta-analysis in criminal justice research:
1. Increased statistical power. By combining data from multiple studies, meta-analysis provides a larger sample size than any individual study. This increases the statistical power to detect effects that may not be significant in smaller individual studies.
2. Reduced sampling error. A meta-analysis incorporates data from different samples, locations, time periods, etc. This reduces the influence of sampling error and chance associations in any one study. The effects are more likely to generalize across contexts.
3. Ability to answer new questions. By bringing together data from many studies, a meta-analysis can answer questions that have not been addressed by any single study. It can examine

Advantages of multimodal biometric system: 1. Nonâuniversality: Multimodal biometric system
solves the problem of non universality which is occoured in unimodal biometric systems.For
example,if the persons cut finger prevents him from successfully enrolling into a fingerprint
system,then the availability of another biometric trait,say face,can be used in the inclusion in the
biometric system. 2. Indexing Largeâscale Biometric database: Multimodal biometric systems can
make easy filtering of large scale biometric databases. 3. Spoof Attacks: It becomes increasingly
difficult for an impostor to spoof multiple biometric traits of a legitimately enrolled individual. 4.
Noise in Sensed Data: Multimodal biometric system considers the problem of noisy data.During
preprocessing of image,filteration of image is carried out.and the noise from image is removed out.
5. Fault tolerence: A multimodal biometric system may also be viewed as a fault tolerant system
which continues to operate even when certain biometric sources become unreliable due to sensor or
software malfunction, or deliberate user manipulation. VII. Applications of Multimodal Biometric

2. Example Of Probabilistic Approach
Probabilistic Approach
In addition to univariate analysis and discriminant analysis, researchers also tried to explore
probabilistic prediction of corporate bankruptcy. Zavgren (1985) opined that the models which
generate a probability of failure are more useful than those that produce a dichotomous
classification as with multiple discriminant analysis.
Option to Default Methodology
Merton (1974) applied the option pricing method developed by Black and Scholes (1973) to the
valuation of a leveraged firm and relates the risk of default to the capital structure of the company.
According to this model, "The firm's equity can be seen as a European call option on the firm's
assets with a strike price equal to the book value of the firm's liabilities. The option like property of
the firm's equity follows from the absolute priority rule with respect to which the shareholders can
be seen as residual claimants with limited liability. This limited liability gives the shareholders the
right but not the obligation to pay off the debt holders and to take over the remaining assets of the
firm."

done by minimum distance classifier. The model using 15 selected HSI texture features got the best
classification accuracy (95.6%), which recommended that it would be best to use a reduced hue,
saturation and intensity texture feature set to differentiate orange diseases. The HSI_15 model, I_11
and HSI_39 models achieved classification accuracy 95.6%, 81.11% and 95.6% respectively.
Bauer et al. [10] developed algorithms for the automatic classification of leaf diseases based on

social behavior of animals cherishes a flock of birds finding a food supply or a school of fish
protecting themselves from a predator. A particle in PSO is analogous to a bird or fish flying through
a search (problem) area. The movement of every particle is coordinated by a rate that has each
magnitude and direction. Every particle position at any instance of your time is influenced by its
best position and also the position of the most effective particle in an exceedingly drawback area.
The performance of a particle is measured by a fitness worth that is drawback specific. The PSO
rule is analogous to different biological process algorithms. In PSO, the population is that the range
of particles in a drawback area. Particles square measure initialized arbitrarily. Each particle can
have a fitness worth, which is able to be evaluated by a fitness perform to be optimized in every
generation. Each particle is aware of its best position pbest and also the best position so far among
the whole cluster of particles gbest. The pbest of a particle is that the best result (fitness value) to

Plans. Moving on, it gives description about various assumption that an organisation needs to
consider before they start following the Positive Accounting Theory approach. Two main
assumption the research paper is based on are:
Individual act to maximise their own utility. (Article) This assumption is also used by Gordon
(1964) in an early attempt to derive positive accounting theory. Gordon model and variants of it,
were also tested know as the "smooth" literature.
Management utility is a positive function of the expected compensation in future periods and
decreases the firms reported earning.

Techniques in Machine Learning The classification of the data is the problem to observe new
numbers of discrete categories. The aim is to learn a model making accurate predictions on new
observations based on a set of data points. For example, for the observations set, x1, ..., xn, the
corresponding categories, y1, ..., yn, where yi â{â1, +1}. Here, yi=â1 refers to category of failure
region, and yi=+1 refers to safe region. A new observation, x value, is assigned to one of these
categories. The three popular classification techniques are explained: (1) Kânearest neighbor
(KNN), (2) support vector machine (SVM), and (3) naĂŻve Bayes classifier (NBC). The given
algorithms here include both deterministic and probabilistic classification approaches. 3.1 Kânearest
Neighbor In the machine learning, one of the simplest method for classification is the Kânearest

5. What are the primary characteristics of residential mortgage loans? Why does the ratio of
adjustableârate mortgages to fixedârate mortgages in the economy vary over an interest rate cycle?
When would the ratio be highest?
11. Residential mortgage contracts differ in size, the ratio of the loan amount to the value of the
property, the maturity of the loan, the rate of interest of the loan, and whether the interest rate is
fixed or adjustable. In addition, mortgage agreements differ in the amount of fees, commissions,
discounts, and points that are paid by the borrower.
The ratio of adjustableârate mortgages to fixedârate mortgages is lowest when interest rates are low
because borrowers prefer to lock in the low market rates for long periods of time. When rates are
high, adjustableârate mortgages allow borrowers the potential to realize relief from high interest
rates in the future when rates decline.

For methodology, it was fortunate that I got the opportunity to join the Directed Reading Program
on statistical methods, ranking soccer teams in cooperation with Dr. Steve. Because outcomes
involving multiple categories occur more often, we wanted to compare and improve existing
ranking methods, and made them suitable for more classifications. For example, primarily, there
was only one classification: scores. To advance, currently, classification of yardages would also be
considered when ranking. After collecting unstructured data online, we used least squares to get the
squared matrix for Massey 's Method but found it failed to cover multiple categories simultaneously.
After research and comparison of other methods, we found that Markov Method succeeded because
the weights can be assigned to eigenvectors of normalized stochastic matrices. Since we have found
the desired method, we reached the agreement that the comparison between the two methods was
consequential here. The results by using the two methods of ranking the same set of scores were
different. Therefore, on the seminar, I concluded that Markov methods outperformed Massey's
Method in the research, but further research suggests that Massey's Methods have a better
performance under some circumstances. It is the charisma of data science that analysts should adjust

In contrast, QDA made mistakes on 49% of the observations, but has a relatively high accuracy
(81%) on people that defaulted on the next month's payment. In fact, other methods such as KNN,
logistic regression that achieved similar overall prediction accuracy also face the small problem of
low accuracy on people that defaulted. Undoubtedly, the overall prediction accuracy is very
important for the banks when making predictions. However, we might consider which type of
mistake we would like to avoid more. For the banks, not issuing loans to people who are actually
going to repay would only cause a small loss on interests. However, issuing loans to people who are
going to default would cause a big loss on the unpaid loans. Thus, it is reasonable to believe that
accurate selection of people who are going to default is of higher priority to the banks. In light of

Introduction
Predictions are an important component of determining the financial progress of a business.
Business decisions rely on forecasting techniques to predict things such as price movements or
overall success in markets. In the attempt to forecast market predictions, it must be assumed that
future occurrences may be partly based on present and past data (AbuâMostafa, Yaser S 1996).
Further assumptions must be made to conclude that there is a predictable pattern in past data. There
is evidence for both the idea that financial market forecasting is futile due to the unpredictable
nature of finance, as well as for the idea that financial markets are predictable to an extent. The
consequences of financial decisionâmaking imply an inherent need for the use of forecasting tools
in making predictions about future occurrences. The issue resides in the fact that there is an
abundance of data and information that must be organized and interpreted. A number of techniques
may be used to manage present and past data in order to create a forecast prediction, though with
more research and trials, neural networks have been shown to be superior in performance.
Traditional Techniques Neural networks provide an alternative solution to the traditionally used

The history of consumer credit scoring can be dated back to half a century ago [3]. However, history
records the same approach was used to identify groups in a population even before. In 1936 Fisher
came up with the rst approach a method that identi ed various groups in a population. He was keen
to nd out the di erences between two varieties of iris through the measurement of the physical
sizes of plants, thus ascertaining the di erence in the origins of skulls using their physical
measurement. In 1941, Durand discovered that the same credit scoring technique could be used to
distinguish between good and bad loans. Though his research project was for the National Bureau of
Economic Research, it wasn 't used for any predictive purpose. Due to the positive e ect of credit
scoring in credit cards, banks in the 1980s started using credit scoring in personal , home and small
business loans, a method which is still utilised till date [1]. Credit unworthiness has always been a
problem encountered by the nancial sectors as they are faced with lapses regarding the credit they

Ethics, deriving from the Greek ethos meaning character (Jennings, 2010), are the moral principles
that govern a person's behaviour or the conducting of an activity (Oxford Dictionary, 2015b) and
establish the foundation of presentâday research (Cropley, 2008; Flick, 2006). They are the norms
of conduct that distinguish between acceptable and unacceptable behaviour (Resnik, 2011) and
establish the values essential for the collaborative work between the researcher and the research
subject (Jennings, 2010; Veal, 2006). The research at hand is therefore in accordance with the
ethical principles as specified by Jennings (2010) and Veal (2006). This includes the free choice of
participation in the research, the confidential usage of sensitive data received from respondents and
the avoidance of harm to participants (Jennings, 2010). Besides, before the completion of the

Increasing Student Retention: A Predictive Model of Undergraduate Degree NonâCompletion
Abstract
This study seeks to develop a predictive model of college student dropout, using aggregate high
school variables and individual postsecondary achievement variables to predict nonâgraduating
students' academic year of departure. After performing multiple linear regression and discriminant
function analysis, the research found that a cohort of students admitted in the fall 2007 semester
from several universities could be assigned an academic year of departure using data readily
available by the end of a student's third academic term. The university can use this model to predict
student departure and improve the effectiveness of student retention efforts by focusing on targeted
times when atârisk students are predicted to drop out.
Introduction
While many academic, psychological, and institutional variables influencing undergraduate student
dropout have been studied, these factors have generally only been examined using models that treat
student dropout as a binary, dependent variable. One of the shortcomings of using logistic regression
in the study of undergraduate dropout is that it restricts the study's ability to infer when a given
student is likely to drop out. In contrast, the present study considered undergraduate dropout as
occurring over a set of intervals, in this case academic terms, and sought to identify those crucial
times when students are considering departure

24. Profiling of MicroRNA Expression in Myocardial Samples
Purpose of the study:
This study was aimed to perform genomeâwide profiling of microRNA (miRNA) expression in
myocardial samples of patients belonging to different diagnostic groups (dilated cardiomyopathy
(DCM), ischemic cardiomyopathy (ICM), aortic stenosis (AS), and nonfailing controls).
Background:
Heart failure (HF) is one of the main causes of morbidity and mortality worldwide, with dilated
cardiomyopathy being the most common type (1,2). It has been estimated that around 5.1 million
American adults have HF and its prevalence was projected to increase 46% from 2012 to 2030 (2).
For this reason, huge efforts were devoted to identify the underlying pathophysiological and
molecular aspects of HF aiming to develop effective diagnostic and therapeutic strategies to
improve the prognosis of the disease (3,4).
Heart failure patients have many pathological changes in their cardiomyocytes' gene expression that
impair cardiomyocytes survival and contraction resulting in cardiac hypertrophy and failure (5,6).
MicroRNAs â small noncoding RNAs with approximately 22 nucleotides in length â are negative
regulators of gene expression at postâtranscriptional level (7). They are implicated in the
pathogenesis and progression of various pathological conditions including cardiovascular diseases,
diabetes mellitus, hypertension, and cancer (4). Interestingly, single microRNA can target various
genes, and an individual gene can be controlled by multiple microRNAs. So far, over 700

25. The Physics Of Infrared Radiation
A vibration can result in an absorption peak of infrared radiation, only if there is a change in the
dipole moment of the molecule. The larger this change, the more intense will be the absorption
band. Furthermore, the electron polarity vectors in the covalent bond should not cancel out i.e the
covalent bonds must be asymmetric. Asymmetrical bonds carry a net polarity vector and show
absorption peaks; bonds that are centered along the plane of symmetry cancel out their polarity
vectors upon stretching and there is no net change in dipole moment. Such molecules are known to
be infrared inactive. An infrared spectrum is the plot of absorbance (or % transmission) against the
wavenumber (cmâ1) (Rehman et al., 2012). Wavenumber is defined as number of waves in a length
of one centimeter and is a commonly used unit for representing spectral regions. Wavenumber is
linear with energy and is expressed with the following equation.Significant parts of the spectrum are
the regions where the molecule absorbs the infrared energy. These are shown as characteristic
absorption peaks. A molecule can only absorb radiation when the incoming infrared radiation is of
the same frequency as one of the fundamental modes of vibration of the molecule (Stuart and
Barbara, 2004). The modes of vibration usually encountered include bending, stretching, wagging
and out of plane vibrations. These molecular vibrations result in changes in dipole moments of the
molecular groups and the resulting vibrating

29. Children 's Manifest Anxiety Scale
Abstract
The Revised Children's Manifest Anxiety Scale is one of the most widely used selfâreport measures
of anxiety in youth. It is used to diagnose overall anxiety in youth and also to characterize the nature
of that anxiety. The purpose of revising the Children's Manifest Anxiety Scale (CMAS) was to
shorten the administration time, increase the clarity of the items, and reduce the reading level.
Reliability and validity data appear to be adequate, though the internal consistency estimates for
some of the subscales of the RCMAS are rather low. While selfâreport measures, such as the
RCMAS, appear to be good at demonstrating convergent validity, they often struggle with
demonstrating discriminant validity. Further reliability and validity data is analyzed, and strengths
and weaknesses of the measure are discussed. Review of the Revised Children's Manifest Anxiety
Scale
The study of child and adolescent anxiety and depression has become an increasing concern over
the past quarter of a century. With this increasing concern comes a need to establish
psychometrically sound measures specifically geared toward a youth population. One of the most

31. Advantages And Disadvantages Of Eye And Face Recognition
Sudeep Sarkar et.al.[10] Researchers have suggested that the ear may have advantages over the face
for biometric recognition. Our previous experiments with ear and face recognition, using the
standard principal component analysis approach, showed lower recognition performance using ear
images. We report results of similar experiments on larger data sets that are more rigorously
controlled for relative quality of face and ear images. We find that recognition performance is not
significantly different between the face and the ear.
Haitao Zhao, Pong Chi Yuen says face recognition has been an active research area in the computerâ
vision and patternârecognition societies [11] in the last two decades. Since the original inputâimage
space has a very high dimension, a dimensionalityâreduction technique is usually employed before
classification takes place. Principal component analysis (PCA) is one of the most popular
representation methods for face recognition. It does not only reduce the image dimension, but also
provides a compact feature for representing a face image. In 1997, PCA was also employed for
dimension reduction for linear discriminant . PCA is ... Show more content on Helpwriting.net ...

32. Forensic And Age Determination Of Blood Stains
Forensic approaches to age determination of blood stains Among the many pursuits of forensic
scientists, one of the foremost attempts is that of establishing time of death of a victim by use of
whatever evidence is available. Even though some calculations for estimations are claimed to be
available to a few branches of the forensics community, such as medical examiner determination by
use of internal temperature of the body, or the onset of rigor and livor mortis, or that of the
entomologist 's estimations based on the pupal and larval stages of different carrion insects, it may
be that the body is in such an advanced state of decay that these calculations cannot give an accurate
calculation, or, even worse, that a body may be absent. In light of such possibilities, it may however
be possible to use other types of evidence to establish time of death, time of deposition, and render a
partial, if not full reconstruction of events on the scene based on the age and order of deposition of
other evidence. Bloodstains represent one such potential piece of evidence that, aside from having
the possibility of providing a link to a person by DNA, may allow investigators to determine the
time of deposition, and perhaps aid in the reconstruction of the purported events. Attempts to
establish the age of bloodstains have been made since early 1900s (Bremmer et al., 2012), but no

Speaker reognition using Mel Frequency Cepstral Coefficients(MFCC)
Abstract Speech processing has emerged as one of the most important application area of digital

recognition, speech analysis, speech synthesis, speech coding etc. The objective of automatic
speaker recognition is to extract, characterize the discriminant features and recognize the
information about speaker identity. In this paper we present a voice recognition system based on
Mel Frequency Cepstral Coefficients (MFCC) and vector Quantization (VQ). This technique has an
advantage that it creates fingerprint of human voice by exploiting human acoustic system and
cepstral analysis. MFCC is widely accepted as a baseline for voice recognition due to these unique
features.

Omnitel Pronto Italia's greatest strength was its customer service. With sales below expectations,
Omnitel Pronto Italia performed extensive market research to identify the needs of its customer
segments.
Through analysis, a need for a new pricing strategy was evident. From the research, it was
determined that consumers viewed the monthly usage fee as a tax and deeply resented it, they did
not want to pay an activation fee and only wanted to pay for services used. Through the competitor
analysis, it was found that Telecom Italia Mobile (TIM) had a strong distribution channel and was
primarily directed to upperâclass income individuals who used cellphones as a status symbol. As
they were essentially a monopoly, their marketing costs were low. From a customer perspective,
consumers were impulsive and wanted different rates for local calls, long distance and international
calls. With interview with over 5000 current and potential customers, it was also determined that
there was low brand loyalty, high consideration scores on activation cost and disliked the monthly
fee.
Therefore, Omnitel Pronto Italia details a decision case where the company is looking for a strategy
that will differentiate the brand, build market share, and maximize profits all while avoiding a price
war with its leading competitor TIM.

A. Principal Component Analysis
PCA is a classical feature extraction and data representation technique also known as Karhunenâ
Loeve Expansion [20, 21]. It is a linear method that projects the highâdimensional data onto a lower
dimensional space. It seeks a weight projection that best represents the data, which is called
principal components. Fig.1 Schematic illustration of PCA
Principal component analysis seeks a space of lower dimensionality, known as the principal
subspace and denoted by the magenta line, such that the orthogonal projection of the data points
(red dots) onto this subspace maximizes the variance of the projected points (green dots). An
alternative definition of PCA is based on minimizing the sumâofâsquares of the projection errors,
indicated by the blue lines as described in figure 1.
PCA is described as let a face image be A(x, y) be a twoâdimensional N by Narray. The training set

More specifically, we sought to use brain activity measurements of ERPs to reconstruct images. A
recent study used functional magnetic resonance imaging (fMRI) to measure brain activity in visual
cortex as a person looked at several hours of movies. We then used these data to develop
computational models that could predict the pattern of brain activity that would be elicited by any
arbitrary movies (i.e., movies that were not in the initial set used to build the model). We used EEG
data to measure brain activity during stimulus. Then created a system for preprocessing the data to

Menstrual cycle is a process experienced by every female at one point in their life cycle. In the
olden days a young lady experiences her first menstruation in her late teens or early twenties. In
recent times, however, some begin their menstrual cycle as early as nine years. The age at menarche
(the first time a girl or a young woman menstruates) is widely considered as an important landmark
in sexual maturity. However it varies widely between the same people. These variations has been
attributed to a number of possible causes such as; advancement in technology, health care delivery,
weather and climate change, food, daily activities, socioâeconomic activities, lifestyle and many ...

Despite variability, most normal cycles range from 21 to 45 days, even in the first gynaecologic
year, although short cycles of fewer than 20 days and long cycles of more than 45 days may occur.
Because long cycles most often occur in the first 3 years post menarche, the overall trend is toward
shorter and more regular cycles with increasing age. By the third year after menarche, 60% to 80%
of menstrual cycles are 21 to 34 days long, as is typical of adults. An individual's normal cycle
length is established around the sixth gynaecologic year, at a chronologic age of approximately 19
or 20 years.
Two large studies, one cataloguing 275947 cycles in 2702 females and another reporting on 31645
cycles in 656 females, support the observation that menstrual cycles in girls and adolescents
typically range from 21 to approximately 45 days, even in the first gynaecologic year. In the first
gynaecologic year, the fifth percentile for cycle length is 23 days and the 95th percentile is 90 days.
By the fourth gynaecologic year, fewer females are having cycles that exceed 45 days, but
anovulation (the state of not ovulating because of a medical condition, suppression by drugs or
menopause) is still significant for some, with the 95th percentile for cycle length at 50 days. By the
seventh gynaecologic year, cycles are shorter and less variable, with the fifth percentile for cycle
length at 27 days and the 95th percentile at only 38 days. Thus, during the early years after

43. The Data Mining Of Finance
Data Mining in Finance 1. Introduction Data mining is used to uncover hidden knowledge and
patterns from a large amount of data. In finance, there is enormous data which generates during
business operations and trading activities. Extracting valuable data from them manually might be
unable or spend a lot of time. As a result, data mining plays an importance role of discovering data
that can be used to increase profits and evaluate risks of strategic planning and investment. The data
mining methods in finance are derived from statistics, machine learning, and visualization. The most
commonly used methods are Decision Trees, Neural Networks, Genetic Algorithms, and Rough Set
Analysis (Hajizadeh, et al., 2010). Due to prediction and ... Show more content on Helpwriting.net

Prior forecasting method is the prediction based on the growth rate of fundamental factors such as
earningâperâshare, book value, and invested capital. Another common method for forecasting is
time series analysis. The traditional analysis uses regression models to discover market trends.
However, financial time series are complex, noisy, and nonlinear pattern. As a result, later
techniques have applied artificial intelligences; the most popular technique is neural networks
(Zhang Zhou, 2004). According to Refenes's experiment (1994), the backâpropagation networks,
a type of neural network, predicts more accurately than regression models on the same datasets.
Other techniques are ARMA and ARIMA model, genetic algorithm, and random walk. Pai and Lin
(2005) introduces the A hybrid model ARIMA and support vector machine which give better result
than single ARIMA. Edward Tsang et al. (1998) proposes EDDIE, a tool which constructs a genetic
decision tree to evaluate whether a stock price increases in a specified time. JarâLong and ShuâHui
(2006) proposes a twoâlayer bias decision tree with simple technical indicators. Typically, the input
variables of prediction models are daily price, volume, rate of change, and technical indicators, for
example, moving average (MA), relative strength index (RSI), and volatility (Vol). 2.2 Foreign
