    What Is Reverse Merger, And Is It For Everyone? Part 1
    A reverse merger is a method used by many small and mid-cap companies to initially go public, its the purchase of, and reverse merger into, an existing public shell company. This is inexpensive compared with conventional Initial public offerings (IPO). This is also a simplified fast track method by which a private company can become a public company.In a reverse merger, an operating Private company merges with a public company that has little or no assets, nor known liabilities (the "shell"). A shell is what remains of a once public company that has ceased to operate, by going bankrupt or liquidation of assets. In some rare instances, the shell may have some amount of cash remaining for investment into the new enterprise. The public corporation is called a "shell" since all that exists of the original company is its corporate shell structure and shareholders. The private company owners obtain the majority of the shell corporation's stock (usually 90-95%) through a new issue of stock for the private enterprise or asset.The public corporation will normally change its name to the private company's name and elect a new Board of Directors which will appoint the officers. The public corporation will usually have a base of shareholders sufficient to meet the 300 shareholders requirement for eventual admission to quotation on the NASDAQ Small Cap Market or American Stock Exchange (if the private company's financial condition substantiates other NASDAQ or AMEX requirements). The company must file a form S-4, this form is use to register securities in connection with Business combinations and exchange offers. although som

    Make Money from your Hobby
    Well, making websites have been a hobby for me for more than two years. It feels so nice when you see people from almost the other side of the globe clicking away on your website. Really gives the impression that the world is indeed getting small.And it is even more a happier proposition if your hobby can get you money! yes; not little, but as high as $240 per day (atleast I was only able to make this much.There are people who can make as high as $700 per day).How do you go about it? Ok, lets say your hobby is writing. And probably you are here on blogger because, you want to write. Now, let me tell you how you make money with this on a website.First, go deeper and deeper into the world of writing to find what interests you most. Probably say, you enjoy writing stuffs that kids like. This looks like a nice niche,right? Google related keywords to see the kind of sites related to kids writing.Now, you decide to make a site where you will publish stories for kids. Now, if you were to go and tell a kid to give you his written work, how would you do it? Visualize and write a few lines. Now, this is going to be the homepage content. Before you launch the site, get a few stories from children you know or from local school or elsewhere on the net and publish them.How Do I Make MoneyGood work..You are doing something in the area of your interest.

    As we know, decision making is the fundamental job of managers and there are various information systems i.e. Management information systems (MIS), Executive information system (EIS) that are helping managers in decision making process. Our central consideration point of this article is DSS and its roles in management perspectives. We will discuss –

    • The role played by DSS in the process of decision making
    • The changes coming in scenario about the role of DSS in decision making.
    DSS is a system that supports technological and managerial decision making by assisting in the organization of knowledge about structured, semi structured, or unstructured issues.

    Decision Support Systems (DSS) are a class of computerized information system that supports decision-making activities. DSS are interactive computer-based systems and subsystems intended to help decision makers use communications technologies, data, documents, knowledge and/or models to complete decision process tasks.

    Decision Support Systems have evolved over the last 25 years from inflexible mainframe systems, to isolated PC tools, to client/server data dippers, and now to high-performance and extensible enterprise decision-support applications, often involving the organization’s intranet. At the same time, the relationship between the IT Department and users has evolved from stormy to co-operative.

    The huge umbrella of decision support systems (DSS) has long provided a welcome gathering spot for those interested in building software applications based on a mixture of models, data analysis, and powerful interfaces. DSS attracts practitioners, scholars and students from a range of fields including information systems, operations research/management science, computer science, psychology and other business disciplines.

    The problem: There has been a virtual revolution in terms of spreadsheet based management science and operations management courses that seems to have stuck in business schools. Spreadsheets have evolved into a quite capable platform for end-user decision support modeling.

    For example, within Microsoft Excel, this evolution has resulted in the inclusion of Solver for optimization, Pivot Tables, database connectivity, numerous mathematical and statistical functions and the Visual Basic for Applications (VBA) programming language.

    The problem is coming from this picture where instead of using management skills for making decision, managers are very much dependent on DSS tools for making decisions. It might be more crucial when new managers will have lack of management skills and they will totally dependent on DSS tools.

    So, we can make questions:

    • What are the reasons behind that managers are depending so much on DSS tools?
    • What should be the optimized ratio of using desktops and management skills for decision making?
    My Idea: First of all we have to understand decision making model: the set of activities that DSS environments support. The key elements of this model are fairly common, and include:

    • A decision-maker: an individual or group charged with making a particular decision.
    • A set of inputs to the decision-making process: data, numerical or qualitative models for interpreting that data, historical experience with similar data sets or similar decision-making situations, and various kinds of cultural and psychological norms and constraints associated with decision-making
    • The decision-making process itself: a set of steps, more or less well-understood, for transforming the inputs into outputs in the form of decisions,
    • A set of outputs from the decision-making process, including the decisions themselves and (ideally) a set of criteria for evaluating decisions produced by the process against the set of needs, problems or objectives that occasioned the decision-making activity in the first place.

    The Unforeseen Cost Of Summer Holidays
    As you may have noticed, this year's summer has finally arrived in Britain and is asserting its questionable authority (on these shores anyway) more than usual. As such, we are being treated to long, balmy evenings, trips to the seaside, ice cream and the obligatory summer holiday. Not to mention the World Cup of course.However, little in life is free, and while the kids can waltz through the carefree summer months oblivious to the costs of the holiday's innocent pleasures, the parents are left footing the bill.Unfortunately for Britain's parents, school summer holidays are "one of the most stressful times" due to the expense involved. Recent research, cited by the Sunday Herald, reveals that parents pay around ?1,700 to entertain their kids or pay for summer childcare over the six-week break. The National Lottery study found that the average amount spent on childcare is ?463, while the average spent on day trips ranges from ?25 to ?56. Ian Maxwell of campaign group One Parent Families Scotland warned that summer holidays "can turn into a bit of a nightmare for single working parents". And these costs don't even include a family holiday abroad. Often parents are caught unawares by the inflated costs of flights during the school holidays and overlook essentials such as travel insurance and bank charges for using a card abroad.Travel insurance, for example, is a holiday must, yet 13 per cent of holidaymakers ventured abroad without necessary cover in the last 12 months – perhaps because they didn't have the disposable cash so they decided to take an unnecessary risk. However, neglecting to take out travel ins

    Configuring NTP On Your Linux Server
    The Network Time Protocol (NTP) defines a set of algorithms for the dissemination of time across the Internet. The NTP protocol can be used to synchronise the system time on your Linux Server with a highly accurate Internet time reference.This article describes how to configure the Network Time Protocol (NTP) daemon on your Linux server to synchronise with an Internet based NTP server. It also provides a list of well-know public Internet time references.Obtaining the NTP Source Code DistributionThe Linux NTP source code distribution is publicly available ‘open source' software. The distribution can be freely downloaded from the NTP web site ‘ntp.org'. The latest NTP version for Linux is 2.4.2. A port is also available for Windows platforms, but the primary development platform for NTP is the Linux operating system. A number of Linux based operating systems such as Mandrake and Redhat offer NTP as an installable RPM package.Once download is complete, the NTP distribution should be configured and compiled on the host computer.Configuration of the NTP DaemonThe NTP daemon is configured through entries in the primary NTP configuration file ‘ntp.conf'. The NTP configuration file contains a list of commands that instruct the daemon to synchronise with a specified NTP server. NTP servers are specified using the ‘server' command followed by the domain name of the server thus:server ntp2c.mcc.ac.uk server ntp.cis.strath.ac.ukA number of access control options are also available to restrict the use of your NTP server by network time clients.

    Converting Print Advertising For Use On The Web - A How-To
    Contrary to the beliefs of some, advertising for web and print are very different. Converting print ads for use on the web is very tricky. What has been very successful on paper may have no impact at all on the screen. When I am asked “How do I convert my print ads to web?” my answer is simple: don’t! Web and print are so vastly different that I believe you should never build your web pages based on a print ad.There are certain rules that web design must follow that simply don’t apply to print. One of my colleagues, Tim Pattison, broke these rules down very concisely recently: Usability Browser compatibility Designing within the constraints of (X)HTML Accessibility These are the four rules that web design must follow. I will explain these rules in detail later. For now though we need to talk about copywriting. As I said in my last newsletter Web Site Templates and Their Benefits, the most important part of your website is content. Search engines and disabled users don’t care how your site looks. They only care about the information your site presents. The reason I’m coming back to this is to explain that writing web copy is an entirely different ball game from writing print copy. Quite possibly the best resource for writing web copy is the book “Web Copy That Sells” by Maria Veloso. It outlines the differences between the two and gives great techniques to writing for the web. I will be revisiting this topic in my newsletters to come, so make sure you visit often.The four rules exclusive to web design: usability, browser compatibility, design w

    Online Car Loans Helps You To Purchase You Dream Cars
    Are you thinking of purchasing a car? But you cannot purchase it because you are facing financial problems. If this is the reason then relax yourself. Only the thing you have to do is to click online car loans.Car loans are classified into secured and unsecured car loans. In secured car loans borrower have to provide collateral against the approval of loans. Using of collateral means pledging your car to the lender. In other words, lender is authorized to repossess the car if the borrower falters from making repayments through legal procedure. In unsecured loan borrower’s property is not at risk. So, lender approves loan based on the borrower’s income and repayment ability. Thus, car loans are both for tenants and home owners.The rate of interest in car loans is low. Borrowers are benefited by comparing the various interest rate offered by numerous lenders. The borrower must always go for the reasonable interest rate available.Car loans are also approved to every sort of persons. Bad credit history holders such as County Court Judgement, defaults can also apply for the loan. In such cases lenders may demand security from the borrower.The car loans are long term loans. The borrower will have to repay through monthly instalments. In long term loans the burden of payment for the borrower is less. The borrower enjoys flexibility of payments in online car loans. As there is flexibility in instalments, so the borrower can purchase costly cars.Online car loans are intended for people with low or medium income group. The procedure of applying is easy and intelligible for common public. For quick approval

  • As soon as we look at this model, we realize that talking about decision support systems outside of a particular domain of decision-making is not particularly useful.

Put simply, commercial decisions, in the aggregate, have the shorter timeframes and higher associated risks (including extinction) than either public sector or not-for-profit decisions, and as such would presumably require the most assistance from information technology.

    For this reason alone, this essay limits its scope to commercial decision support systems: IT infrastructure designed to support the decision-making processes in publicly-held and private firms that compete in open markets for customers, revenue and market share.

    How do DSS environments support decision-making? DSS environments support the generic decision-making model above in a number of ways:

    • In decision preparation, DSS environments provide data required as input to the decision-making process. This is all about data mart and data warehousing environments do today.
    • In decision structuring, DSS environments provide tools and models for arranging the inputs in ways that make sense to frame the decision. These tools and models are not pivot tables and other aspects of data presentation found in query tools. They are actual decision making tools, like fault tree analysis, Bayesian logic and model-based decision-making based on things like neural networks.
    • In context development, DSS environments again provide tools, and provide the mechanisms for capturing information about a decision’s constituencies (who’s affected by this decision), outcomes and their probabilities, and other elements of the larger decision making context.
    • In decision-making, DSS environments may automate all or part of the decision-making process and offer evaluations on the optimal decision. Expert systems and artificial intelligence environments purport to do this, but they work only in very limited cases.
    • In decision propagation, DSS environments take the information gathered about constituencies and dependencies and outcomes and drive elements of the decision into those constituencies for action.
    • In decision management, DSS environments inspect outcomes days, weeks and months after decisions to see if (a) the decision was implemented/propagated and (b) if the effects of the decision are as expected.
    What is required is to-

    • Pick the class of decision-making processes to focus on,
    • Narrow the range of inputs, the range of activities and the differences in models and methods,
    • Most importantly, to understand where technology ceases to play any meaningful role in decision-making, and where policy becomes the determinant of the quality and quantity of decisional effectiveness.
    Related work:In the same context, we should understand the components of Decision support systems (DSS).Components of DSS The primary components of a DSS are a database management system (DBMS), the User Interface (Dialog) Subsystem, the Knowledge Based (Management) Subsystem.

  • Database management system (DBMS):- An appropriate database management system must be able to work with both data that are internal to the organization and data that are external to it.
    • Database
    • Database management system
    • Data directory ( A database must contain data about the tables & all other objects)
    • Query facility
    The User Interface (Dialog) Subsystem: - Dialog generation and management system is designed to satisfy knowledge representation, and control and interface requirements.

    Typical information that a decision support application might gather and present would be:

    • Accessing all of your current information assets, including legacy and relational data sources, cubes, data warehouses, and data marts.
    • The consequences of different decision alternatives, given past experience in a context that is described.
    • Projected revenue figures based on new product sales assumptions.
