LINEAR MODEL-BUILDING Linear (regression) models are used in a variety of business situations for a variety of purposes. One reason for their popularity is that they can be easily understood and implemented. All that is needed is data on two or more variables and a computer or calculator. With a minimal amount of effort, a manager obtains (1) an equation for the relationship between the dependent variable (Y) and one or more independent variables (the Xs), (2) a forecast of Y for any given set of X-values, and (3) a host of statistics to complement the analysis. Because so much is obtained so easily, the potential for misuse is great if the model builder is not careful about how the model is built and applied. This note provides guidelines for the effective construction and application of linear models. We begin with a discussion and categorization of the various uses for a linear model. Whether a given model is appropriate for a particular use depends on the way the independent and dependent variables relate to each other. Next, we describe the kinds of possible relationships between Y and X variables, and then we emphasize the kind of relationship between Y and X necessary for each potential application of a...

...This story today is called "A Pair of Silk Stockings." It was written by Kate Chopin Little Mrs. Sommers suddenly acquires fifteen dollars, which seems like a large amount to her. Feeling important and wealthy, she considers how to invest her money, feeling that she must carefully spend the money. During the night, she thinks of a sensible use for the money. She determines that she should spend a dollar or two extra for Janie's shoes, so that they will last longer and be of better quality, and she plans to buy some fabric for her children's clothing. After that, she will still have enough money for new stockings and hats for everyone, which pleases her because her children will have new clothing for the first time in a while. Mrs. Sommers used to have more money long ago, before her marriage, but she does not worry about the past or the future, focusing mostly on the present. Mrs. Sommers is used to cheap purchase, but today she is tired and forgets to eat lunch. While sitting on a stool to rest before her shopping, she realizes that her hand has brushed against a pair of two-dollar silk stockings. She continues to feel the splendid fabric and asks the shop girl for a pair in her size. After choosing a black pair of stockings, Mrs. Sommers buys them and goes directly to the ladies' waiting room to change. For once, she abandons thinking about responsibility or about why she is so satisfied at her purchase. She sits in the room for a while, reveling in her stockings...

...then it is skimmed. New bio-engineering technique is then applied to make a protein spinning fluid. This fluid is suitable for wet spinning process through which the final high-grade textile fiber is made. While spinning, a solvent is used by most of the manufacturers and micro-zinc ion is embedded in the fiber which gives it the characteristics of being bacteriostatic and durable. It combines the advantages of both, natural as well as synthetic fibers. Milk protein fiber is a kind of fresh fiber that has very healthy functions. It contains eighteen amino-acids, which are beneficial to human health. It can be spun alone or with cashmere, silk, spun silk, cotton, wool, ramie and other fibers to make fabrics. The fabrics made of these fibers nourish and take care of skin in a very efficient manner by keeping away allergies and even wrinkles.

...Bangladesh garment exports boom despite disasters Published July 09, 2013 AFP * In this photograph taken on June 23, 2010, Bangladeshi women sew clothes in a garment factory in Ashulia. Output from Bangladesh's accident-prone garment sector has increased in June, with demand from foreign retailers still growing despite the country's factory disaster in April. (AFP/File) DHAKA (AFP) – Output from Bangladesh's accident-prone garment sector increased in June, data showed Tuesday, with demand from foreign retailers still growing despite the country's factory disaster in April. At least 1,129 people were killed when the Rana Plaza factory complex collapsed outside the capital Dhaka in April, sparking demonstrations against Western brands and prompting some retailers to threaten to cancel orders. Government data released on Tuesday showed that the country's total exports -- 80 percent of which come from the garment sector -- soared by 16 percent year-on-year in June to $2.7 billion, following an increase of 15 percent in May. "The disasters didn't have much impact. They are scattered incidents," head of the government's Export Promotion Bureau (EPB) Shuvhashish Bose told AFP, referring to the Rana Plaza tragedy and other factory fires that have killed another 130 workers since November. Total exports from Bangladesh, the second-biggest clothing manufacturer in the world after China, grew by 11 percent to a record $27.02 billion in the 2012-13 financial year to June. ...

...SELECTING FABRICS, COLORS, AND SUSTAINABLE FLOORING Charita Y Parker ID121Rp Donna Pennella February 4,2013 Flooring Living Room I chose the Bamboo flooring foe the living room area because it is a truly sustainable harvested grass that regenerates at a speed faster than hardwood. Bamboo mature rapidly but harvesting does not kill the plant. Duro-design uses only fully mature Moso bamboo which is selected for superior strength and maximum hardness. I think it fits in to my overall concept because I believe wood flooring is traditional. Duro Design Ash Brown bamboo flooring Flooring Bedroom I chose carpet for the bedroom because carpet is a natural insulator. Using it in a wall to wall application increases the R-Value or insulation level of the carpet area. Having carpet helps you save money on your utility cost while reducing energy.

...The main objective of their marketing activities is to react swiftly: Zara is able to design, produce and deliver the product to the customer in just one month. The main reason for this is that Zara does not forecast the designed clothing. Fabrics and garments are the only materials to be purchased on the basis of forecasts. Their main strength is to capture real-time information on the shop floor and develop designs on the basis of this information: so-called ‘commercial managers’ conceptualize the type of garments and the kind of fabric it will be made off. Based on this real-time information, garments and its technical specifications are prepared in strong collaboration with other departments along the supply chain. In doing so, the final design is ‘assembled’ on the basis of current customer demand. This gives Zara a strong competitive advantage since they integrated the product development with up-to date marketing activities and information. Also, Zara does not invest in expensive commercials or campaigns. Most of Zara’s marketing budget is spent on information technology and communications to keep ahead of day-to-day trend information. This gives the supply chain flexibility and a competitive advantage. Another important differentiator is that Zara puts more emphasis on offering different styles rather then increasing the volume per item. The flexible supply chain can produce quickly enough, so large numbers in stock does not add value. Their suppliers are found in...

...RAFI, the General Manager of MUHAMMAD RAFI GARMENT INDUSTRIES (PVT) LTD, Lahore Pakistan was trying to implement a management information system. He was facing resistance from Mr. Kashif, his most senior Supervisor. MR. ZAHID RAFI wondered what he could do to overcome this resistance. Company Background Westward Exports was an exporter of ladies cotton garments. It was a private company established in 1971. It was a family run business and all four directors were brothers. Over the past fourteen years the exports of the company had grown from Rs. 0.71 million in 1972-73 to Rs. 59.76 million in 1984. Almost 90% of the exports went to USA. It owned no manufacturing facility of any kind. It purchased cotton cloth from six different textile mills and had the cloth dyed and printed. This fabric was then passed on to 138 stitching subcontractors. The company had been expanding the product line over the years and by 1983 it was exporting about one million garments in over one hundred basic designs. The 100 designs were presented in a large of fabric types, shades, designs and sizes. When seen in the context that the company had to get all these things done through subcontractors, the managerial control of the operations became quite challenging. The directors who had always been actively involved in each and every aspect of the business, and made all the decisions by themselves, felt the heat of changing situations. They appreciated the problem and decided to hire some...

...Colorfastness refers to the resistance of color to fade or bleed of a dyed or printed textile materials against water, light, rubbing, washing, perspiration etc. to which they are normally exposed in textile manufacturing and in daily use. Colorfastness to Rubbing Colorfastness to rubbing test is designed to determine the degree of color which may be transferred from the surface of a colored fabric to a specify test cloth for rubbing (which could be dry and Wet). Crockmeter is the main equipment used in this test. Crockmeter uses a standard pressure and rubbing motion to provide reliable and reproducible test results. Specimens are positioned on the base of the Crockmeter and held in place with the sample holder. The rubbing action is provided by an acrylic "finger" which moves in a straight line with each complete turn of the crank. The reciprocating load arm is weighted to provide a constant 9N load on the sample at all times and a mechanical counter keeps track of completed cycles. Then, the result of the specimen is evaluated using the grey scale of staining. Colorfastness to Washing The main test method of the colorfastness to washing is carried out called AATCC standard detergent WOB (without optical brightener). The test measures the resistance to water of any colored textiles. Launder-moester is the main equipments used with the help of grey scales. Testing procedure (Usages) 1. Attach the multifiber fabric to specimen by sewing or stapling. 2. Place the sample...

...Step 1: Planting and Harvesting the Raw Material: Cotton: Most commnly used raw material for fabric in the world 60% of women’s clothing and 75% of men’s clothing contains some cotton. Oxford cloth: It is very popular shirting fabric, particularly for more casual shirts. It’s a bit thicker than what we’d consider “fine” dress shirt fabrics, and has a hearty feel that is both durable and naturally resistant to wrinkles. Oxford cloths can be found in a variety of qualities. Planting and Cultivation: Farmers plant their cotton using huge mechanical planters that cover 10-24 rows at a time. The planters cut a line in the tilled soil, drop seeds in the line either alone or in small clumps, and cover them back up. Harvesting and Ginning: There are a variety of machines that are used to harvest cotton, including pickers and strippers, named for the way they pull the cotton from the stalk. Step 2: Weaving the Fiber Into Cloth: Weaving has been around for a very long time. The cotton fiber is run through what’s known as a carding machine, which further cleans and purifies the fiber and lines them up into 2-3 soft, straight ropes called slivers. The slivers are then loaded up into a spinning frame, which rotates the fiber at incredible speed, twisting it into recognizable cotton yarn. This yarn is then fed into a loom. The looms weave the cotton yarn into sheets of cloth, known as gray goods, that are shipped to garment manufacturing facilities to be bleached, dyed, or otherwise...

...Global Analysis The United States changed the rules concerning quotas on textiles and apparel imports at the beginning of 2005. This long coming transformation has definitely affected more than just the United States. Several countries have had concerns over this new policy. Firms that outsource the manufactures of their textiles apparel could benefit from this policy. These firms now can outsource anywhere due to the quotas being lifted. The firms can choose who to outsource to based on prices and/or quality. The firms no longer need to worry about which nation has already met its quota. Since the quotas on the US textile and apparel imports have been eliminated, outsourcing firms should have a good advantage. Quiet a few countries have been affected by this policy change. Textile manufactures and workers have seen the consequences of this alteration. China has seemed to benefit from this change. According to the Klako Group, Chinese textile and apparel exports to the US increased by 62.5% overall in the first quarter of 2005. The increase in manufacturing has exposed the workers of China to more labor, but it has not increased the standard of living or improved living conditions. Indonesia is believed to lose a large piece of the textile and apparel division to China. In 2001, the US was the largest market for Indonesia’s textile and apparel exports. According to expresstextile.com, 1.2 million Indonesians are employed in this industry. A decrease in...

...Material ConneXion Exploration Category of textile material of interest and why I currently live with my dog at school and this past summer in New York City. We take two or three times a day. My dog is only a little more than one year old, but the bottom of his paws is already very rough and the vet said it is quite inevitable if he goes outside frequently. In addition, after every walk I clean his feet twice or three times with paper towels and hand sanitizer, since he comes onto my bed everyday. It’s not that dirty in Ithaca, just annoying to get dirt and grass off, but this past summer in New York City, I always had to give his feet three rounds of cleaning until the paper towels used were not all grey. Even after, I was still doubtful that his feet were completely clean. Therefore, this gives dog owners a huge headache. I’ve looked into dog shoes, which take me ten minutes to put on and then annoys my dog so much that he feels awkward to get into his potty position, and dog socks, which retain dirt and every other unwanted matter on the street. I want to find new materials of which dog shoes and socks can be made. Therefore, I narrowed the search on MaterialConnexion by the following: High water resistance, high stain resistance, low thermal conductivity, flexible stiffness, and high scratch resistance. In addition to the general characteristics above, I read through the different choices for more specific characteristics, such as anti-bacterial, antimicrobial, anti-odor...
