Proper mixture yields faint blue flame for maximum heat and minimum soot What is meant by the word chemical? Substance with definite composition Physical chemistry, organic chemistry, and biochemistry Mass-Measure of the amount of matter Matter- Anything that has mass and takes up space How does a pure compound differ from a mixture? Compound is consistent and has properties of itself. Mixtures retain properties of what makes it up Characteristic that defines an entire group of substances How are properties useful in classifying materials? Properties can be used to distinguish substances and separate them Difference between extensive and intensive property Extensive depends on matter that is present and intensive does not Distinguish physical and chemical change PC- change in substance that does not involve a change in the identity of the substance CC- change in which one or more substances are converted into different substances Change in the object.

Company Law Essay Example | Topics and Well Written Essays - 5000 words

Company Law - Essay Example n be altered by special resolution.3 However, any alteration must comply with the provisions contained in the company’s Memorandum of Association and the current Companies Acts. The Memorandum sets out the objects of the company and what the company can do. Therefore in the event a provision of the Articles is inconsistent with the Memorandum it will be overruled.4 Any alteration of the company’s Article of Association must be conducted in good faith and for the overall benefit of the company.5 The underlying rationale is the extent to which the majoritys power is contained so as to prevent majority oppression of the minority. Put another way, the principles of common law and equity effectively bind the majority share holders in the manifest exercise of their powers at the expense of minority shareholders.6 The courts have consistently approached the question of alteration of a company’s Articles of Association with extreme caution. There are many variants that are potentially conflicting. For one thing a fine balancing of the company’s interests and the interests of the members of the company as a body is relevant. The doctrine of majority rule is as equally important to the court as is the protection of the minority from oppression by the majority. Since by virtue of Section 9 of the Companies Act 1985 a majority can alter or amend provisions contained in the Articles of Association, it is important to the court that this is not accomplished by discriminatory or fraudulent means or motives on the part of the majority. The doctrine of majority rule was introduced in Foss v Harbottle. The rationale behind Foss was that any difficulties within the structure of the company ought to be dealt with by ratification by the majority shareholders.7 Inherent in this principle is the courts’ recognition of the company’s right to alter its Articles of Association. Jenkins LJ said, ‘†¦where the alleged wrong is a transaction which might be made binding

The role of HR planning in the resourcing process Essay

The role of HR planning in the resourcing process - Essay Example Presently, demographic shifts, technological changes, environmental instability and global competition have led to a new role for HR planners since resourcing process have grown to be complex than before. Ulrich and Brockbank (2005) pointed out that HR planning involves continuous and systematic process of analyzing a business human resource needs under changing conditions. In addition, it involves development of workforce policies that are consistent with long range effectiveness of a business. HR planning involves forecasting HR needs and designation of the necessary actions involved in the resourcing process such as recruitment, career development and training. HR planning helps to forecast the right numbers of employees and more so in getting the right kind of personnel at the right place within the right time. According to Robertson and Smith (2001), HR planning coordinated the enumerated elements and helps to gather resources the business needs in both long term and short term. HR planning is a vital component for organizational success in the long-run. This paper will discusses role of HR planning in the resourcing process, importance on job analysis, internal and external recruitment tools and selection techniques, importance of effective induction and appropriate retention strategies in respect of recruitment of a cinema manager while at the same time reviewing the current state of the United Kingdom employment market. The following are ways in which HR planning facilitate the resourcing process: The facilitation of pre-recruitment review is a process that involves provision of professional advice as to whether the internal staff should be taken into consideration in filling the vacant positions. A process is then followed in evaluating the staff’s suitability. The staff who were working under the former cinema manager should, therefore, be evaluated to determine if anyone is capable of filling the vacant position. The provision of guidance and expert advice is used in the initial stages of recruitment especially in defining the vacant position, preparing advertisements, advising on and identifying proper channels for advertisement among other important recruitment activities. As such, the HR planners will be resourceful in defining the roles of a cinema manager, identifying the right advertisement channels among other recruitment activities. The HR planner acts as an expert adviser to the selection committee throughout the selection process. This involves briefing the committee members on the appropriate interview techniques and providing
