Contract

...consent of a contracting party has been obtained entered into freely and voluntary. But sometimes the contracting parties entered into contract with some form of pressure which the law regards as improper, and for this reason the victim of such pressure may be entitled to relief. The victim of such pressure may be entitled to relief under the common law of duress and under the equitable rules of undue influence, although in recent years it attempt to introduce into common law a doctrine of inequality of bargaining power. Duress is common law concept based on illegitimate threat made to contracting party. Undue influence developed in equity to deal with situations where there was improper pressure, without any necessarily specific threat. [2] A victim such a pressure may be entitled to relief and the contract will be voidable. Further, certain special statutory provision protected vulnerable parties subject to contract. For example, the statues which protect the most likely victims of inequality bargain power with Unfair Contract Terms Act 1977 and Consumer Credit Act 1974. The legislation also protected the customer against a form of economic duress with The Unfair Commercial Practise Directive 2005/29, [2005], which must be implemented by December 12, 2007 which also protected the customer with specific...

...Some Applications of the Residue Theorem∗ Supplementary Lecture Notes MATH 322, Complex Analysis Winter 2005 Pawel Hitczenko Department of Mathematics Drexel University Philadelphia, PA 19104, U.S.A. email: phitczenko@math.drexel.edu ∗I would like to thank Frederick Akalin for pointing out a couple of typos. 1 1 Introduction These notes supplement a freely downloadable book Complex Analysis by George Cain (henceforth referred to as Cain’s notes), that I served as a primary text for an undergraduate level course in complex analysis. Throughout these notes I will make occasional references to results stated in these notes. The aim of my notes is to provide a few examples of applications of the residue theorem. The main goal is to illustrate how this theorem can be used to evaluate various types of integrals of real valued functions of real variable. Following Sec. 10.1 of Cain’s notes, let us recall that if C is a simple, closed contour and f is analytic within the region bounded by C except for finitely many points z0 , z1 , . . . , zk then k f (z)dz = 2πi C j=0 Resz=zj f (z), where Resz=a f (z) is the residue of f at a. 2 2.1 Evaluation of Real-Valued Integrals. Definite integrals involving trigonometric functions 2π We begin by briefly discussing integrals of the form F (sin at, cos bt)dt. 0 (1) Our method is easily adaptable for integrals over a different range, for example between 0 and π or between ±π.

Education and Gender Equality Within Millennium Development Goals

...Education and Gender Equality within Millennium Development Goals: KSA & China Name: Institution: Course: Date: Declaration I hereby declare that this is my work and nothing has been plagiarized. Every aspect of this work has been appropriately referenced using the APA referencing format. Executive Summary Table of Contents Contents of the report with page numbers, list of tables, and list of figures. Introduction to the Research Topic Education and gender equality are critical components of societal progress and development. They reflect basic rights that require no economic justification. This notion is reflected in the inclusion of gender related developmental and propagative objectives in the Millennium Development Goals (MDGs). Yet it is also a case that education and gender equality has broad and positive implications for economic as well as social development to any nation. A significant decline in child illiteracy and maternal mortality remains somewhat elusive and thus the Millennium Developmental Goals initiative that has been deemed to reduce child illiteracy and promote gender equality coupled with the establishment of women empowerment within all regions of the world is poised with inconsistent progress rates within some certain countries. To deliver such Millennium Development goals and MDG3 and its supporting targets which promotes specifically gender equality and empowers women, it will be critical to elevate...

Women Empowerment

...2. Women Empowerment in Modern India Dr. Shruti Singh For centuries women were not treated equal to men in many ways. They were not allowed to own property, they did not have a Share in the property of their parents, they had no voting rights, and they had no freedom to choose their work or job and so on. Gender inequality has been part and parcel of an accepted male-dominated Indian society throughout history. Women were expected to be bound to the house, while men went out and worked. This division of labor was one of the major reasons why certain evils like 'Sati Pratha', ‘PardahSystem', 'Child Marriage', 'Dowry System', etc. took birth in our society. The traditional Indian mentality assumes that the place of women is mainly concentrated to the household activities like kitchen work and upbringing of the children. There is systematic discrimination against women economically, socially, politically and culturally more so, in India. These discriminations & disabilities are practiced at all levels day in & day out. Women Empowerment is the ability of women to exercise full control over their actions. This means control over material assets, intellectual resources and even over their ideologies. It involves, at the psychological level, women's ability to assert them which has, so far, been constricted by the 'gender roles' assigned to them especially in a culture like India which resists changes. This essay throws light upon the different challenges that are faced by Indian...

Public Finance and Its Different Aspects

...Q. 1 What is public finance? Answer: Public finance Public Finance is the study of Government activities and how the Government finance those activities.Collection of taxes from those who benefit from the provision of public goods by the government, and the use of those tax funds toward production and distribution of the public goods. Distinction between public finance and private finances. Answer: Difference between private and public finance: these are the differences between the private and public finance. 1: Adjustment of income and expenditure: a government first prepares an estimate of expenditure and then means to raise that sum and the individual must adjust his expenditure to his income. 2: Budgeting: the unit for the public budget is one year but an individual needs not balance his budget during a given period. 3: Deficit financing: deficit financing is a peculiar privilege of government but an individual can not do it, unless he is prepared to go behind the bars. 4: Different objectives: an individual tries to maximize his satisfaction or profit from a given amount of resources but the objective of government expenditure is to maximize social benefit. 5: Publicity of finance: budgets are published and the widest publicity is given to them. On the other hand, the secrecy surrounds individual finance. 6: Coercion: a government has to pass a law and compel the citizen to pay a tax while an individual lacks the coercive authority.

Obesity in Australia

...Obesity is chronic condition where there is an abnormal accumulation of fat causing excess body weight which in turn is detrimental causing health issues and ultimately a lower life expectancy. The prevalence of obesity in Australia is 20.5%: 19.1% for males and 21.8% for females. The prevalence of being overweight but not obese was 39.1%: 48.2% for males and 30.2% for females. The number of overweight and obese adults increased from 4.6 million in 1989–90 to 5.4 million in 1995, 6.6 million in 2001 and 7.4 million in 2004–05. Approximately 25% of children are overweight or obese, up from an estimated 5% in the 1960s. (ABS, 2007) (Allman, AI. 2008) In Sydney, 57 per cent of people are overweight or obese, compared to 67 per cent in other areas. This figure is relatively low in comparison to other major cities such as Perth (72 %), South Australia (61.5%) and Victoria (68%). (Markey, A. & Watson, C, 2011). When looking at the population and demographics of obesity it is seen In 2007-08, higher proportions of males aged 18 years and over were overweight or obese (63%) than were females (48%). (ABS, 2007) When comparing age groups in general, rates of overweight/obesity are higher in older age groups, although males and females in the oldest age group (75 years and over) had lower rates. Adult male overweight/obesity rates are higher than female rates across all age groups. (ABS, 2007) In 2004-05, 62% of Aboriginal and Torres Strait Islander males and 58% of Aboriginal and...

Advanced Algorithms

...Vijay V. Vazirani College of Computing Georgia Institute of Technology Copyright c 2001 Approximation Algorithms Springer Berlin Heidelberg NewYork Barcelona Hong Kong London Milan Paris Singapore Tokyo To my parents Preface Although this may seem a paradox, all exact science is dominated by the idea of approximation. Bertrand Russell (1872–1970) Most natural optimization problems, including those arising in important application areas, are NP-hard. Therefore, under the widely believed conjecture that P = NP, their exact solution is prohibitively time consuming. Charting the landscape of approximability of these problems, via polynomial time algorithms, therefore becomes a compelling subject of scientific inquiry in computer science and mathematics. This book presents the theory of approximation algorithms as it stands today. It is reasonable to expect the picture to change with time. The book is divided into three parts. In Part I we cover a combinatorial algorithms for a number of important problems, using a wide variety of algorithm design techniques. The latter may give Part I a non-cohesive appearance. However, this is to be expected – nature is very rich, and we cannot expect a few tricks to help solve the diverse collection of NP-hard problems. Indeed, in this part, we have purposely refrained from tightly categorizing algorithmic techniques so as not to trivialize matters. Instead, we have attempted to capture, as accurately as possible, the individual character...
