In one sentence, describe what the following article is about: You might examine the industry as a whole or an industry segment which targets a particular subset of the general market. For example, you could be investigating the petrochemical industry as a whole, or a narrower niche, like US petroleum refineries. In either case, you'll need to identify the companies that offer services or products similar to those which your company offers. You might also need to conduct some cross-industry research. For example, a game developer may need to compile statistics on the console gaming market, PC gaming market, and handheld gaming market. Government databases contain huge volumes of statistical information on various economic sectors. Some of the best government sources in the United States for industry statistics include the Market and Industry Analysis Statistics published by the United States Census, the Department of the Treasury, FedStats.gov, EconomicIndicators.gov, and the Food and Drug Administration. All publish useful reports and statistics. For other countries, consult federal databases and agencies within your nation, or conduct an internet search with keywords like "government statistics [name of your industry]" to locate relevant information. At least two independent research reports with data on your market should be consulted. Contact private data-collection agencies or industry interest groups for a published report or market analysis relevant to your research. You can also consult experts within your own company. Just bear in mind that their views may be biased or unreliable. There may be more than one trade association for your industry. For instance, if you're in the computer industry, you might consult or request recent industry-wide reports from the Computer & Communications Industry Association, the Association for Interactive Marketing, or the Information Systems Security Association. Whatever your industry, consult trade groups and industry publications to identify info which can provide background info on your industry analysis. Check academic databases such as Google Scholar for published studies on your area of interest. The Encyclopedia of Emerging Industries and the Encyclopedia of American Industries, both published by Gale Research, are also good sources. Make special note of annual revenues in the industry, number of involved companies, workforce statistics, etc. Find statistics about the size of the customer base and buying trends. Cross-check your information against other sources to ensure accuracy. Your industry analysis will be examined thoroughly when you present the final business proposal to investors or stockholders, so ensure your data is solid and sourced properly.
Summary: Define the scope of your analysis. Research your industry with independent government agencies. Compile independent research. Look at trade association data. Consult academic research. Compile relevant data using the sources above.

In one sentence, describe what the following article is about: Thread your needle with matching, lightweight thread, and sew straight across your hem roughly 1/4 inch (6 mm) away from the raw edge. After sewing this line, trim the edge so that there is only 1/8 inch (3 mm) between the thread line and the raw edge. This stitch will end up being on the bottom of your hem. It should help you maintain an even, consistent roll. Fold the raw edge toward the wrong side of the fabric and press in place using an iron. While not entirely necessary, pressing the fold in place will make the hem less likely to unroll as you stitch. Fold the fabric so that the bend falls just past your initial row of stitching. You should see your initial stitching along the underside of the fabric but not from the front. Pick up one thread from the fabric and a small stitch from the edge of your fold. Pull the needle through, but do not pull it taut just yet. Use a small, sharp needle for best results. Doing so will make it easier to pick up single threads along your hem. The stitch made into your fold should be as close to the actual fold as possible. Position it in between your initial line of stitching and the fold itself. The threads you pick up from the front of the actual fabric should be directly above the stitch made into your fold. These threads should also be right above the raw edge. Make sure that you only pick up one or two threads from the fabric. Picking up more will cause the hem to be more visible from the front of the fabric. Each stitch should only pick up one or two threads from the fabric, and the stitches should be spaced roughly 1/4 inch (6 mm) apart. Repeat this until you have 1 to 2 inches (2.5 to 5 cm) of hem stitching. Lightly pull on the thread in the direction of your stitching. The raw edge should roll itself down into your hem, disappearing from sight. Use firm pressure, but do not pull tightly. Pulling too tightly can cause the fabric to bunch up. Smooth out any bubbles or bumps with your fingers. Continue stitching along the rest of the hem in the same manner until you reach the end. Knot off the end and cut off any excess thread. As you get better at the process, you can pull the thread after 4 to 5 inches (10 to 13 cm) of stitching rather than every 1 to 2 inches (2.5 to 5 cm). If completed correctly, the raw edge should be hidden along the wrong side of the fabric and the hem stitching should be barely visible from the front. The hem may already be smooth enough, but if desired, use an iron to press it further. This step completes the process.
Summary:
Sew straight across the raw edge. Fold in the raw edge. Pick up a few threads with your sewing needle. Make a few more stitches in the same manner. Pull the thread through. Repeat along the length of the hem. Iron press when finished.
