Neuro Linguistic Programming-Connector Between Managers and Subordinates

...NLP: CONNECTOR BETWEEN MANAGER AND SUBORDINATE Palwasha Khan Sana Iqbal Sundus Younis Faculty of Engineering Management Center of Advance Studies in Engineering (CASE) Abstract: Neuro Linguistic Programming is thought to be an advance communication tool which incorporates Human cognition, behavioral contour, and unconscious verbal/nonverbal patterns in order to understand the way information is being perceived, processed and acted upon by the individual and how he interact with his environment including the human factor. It is continuously being probed for its impact over successful human interactions and relationship. Usage of NLP in business world is still unexplored in certain aspects. This research paper is meant to study the impact of appropriate NLP techniques over the relationships that typically exist between managers and subordinates. Using a survey questionnaire, data is being collected from employees of a variety of organizations and found out that though mostly, NLP is unconsciously applied in managerial sector, it does play its role in improving the perceived manager-subordinate relationship, through improving the trustworthiness of the managers and the social bonding that exist between the managers and their subordinates. NLP also impacts to a lesser degree upon the feedback process and participative management style of the manager. Currently managers give more credit to importance of NLP techniques in better relationship building than the subordinates...

American Connector Company

...OPERATIONS MANAGEMENT AMERICAN CONNECTOR COMPANY INTRODUCTION About DJC DJC is easily perceived as the typical Japanese manufacturer when considering their core principles. DJC’s corporate objective was profit maximization. DJC emphasised on high quality products at low production costs and thus creating value for the company. Initially, it followed a strategy of coping American products, which were considered to be the most advanced in the world, but over a period of years realised highly efficient manufacturing is critical for gaining competitive advantage over its competitors and thus developed its RND team to produce quality products at par with American counterparts. Facing huge challenge to maintain its current market share in connector business due to increase in labour cost, raw material cost, rising yen and wide penetration of imported goods, DJC chose to build its new plant in Kawasaki Japan to achieve “the ultimate rationalization of mass production”. The plant was established in 1986 and is designed to produce 800 million connectors per year with the aim of achieving three main goals 1. 100% utilization. 2. 99% yield on raw material. 3. Six sigma policy reducing defects to 1 per million units of output delivering high customer satisfaction. The Kawasaki plant is successfully operated by Kawasaki management by carefully integrating decisions and policies meeting company’s goal and objectives.

...Marcus Mason 08/05/2013 Unit 7. Lab 1. New Building-Safety Plan On site Management commits the necessary resources of staff, money, and time to ensure that all persons on the worksite are protected from injury and illness hazards. In addition, management visibly leads in the design, implementation, and continuous improvement of the site’s safety and health activities. Specifically, the highest level management establishes and reviews annually the site’s safety and health policy and ensures that all employees know, understand, and support that policy. All management levels, with input from hourly employees, develop an annual safety and health goal with objectives and action plans to reach that goal. At the end of each year all management levels, with input from hourly employees, evaluate progress in accomplishing the action plans, achieving all objectives, and meeting the annual goal. This evaluation and plan, which also includes an evaluation of the overall safety and health program, results in a written report that includes the next year’s goal, objectives, and action plans, including any remaining action needed to accomplish the current year’s goal. Management ensures that all employees, including themselves, have clearly written safety and health responsibilities included within their job description, with appropriate authority to carry out those responsibilities. Also, management ensures that all employees, including all levels of management, receive performance...

Unit 8. Lab 1. Fiber Optic Connector Assembly

...Unit 8. Lab 1. Fiber Optic Connector Assembly The most critical part, the Cable and Fiber Preparation where the fiber is mounted, is the ferrule. The Ferrule is a long, thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber's cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia), stainless steel and plastic. The ferrule's job is to center and align the fiber and protects it from mechanical damage. The end of fiber is at the end of the ferrule, where the fiber end is polished smooth either flat or with a curvature. The ferrule is mounted in the connector body and then the connector body is attached to the fiber optic cable structure. Finally, a strain-relief rubber boot protects the connector-cable junction. Fiber optic connectors usually do not have the male-female polarity. Most fiber connectors are male only. Instead, fiber connectors mate to each other in fiber adapters, which are often called mating sleeves or coupling receptacles. Fiber optic adapters used to mate different connector types such as a FC connector to a SC connector are called hybrid adapters. Although this approach requires the use of separate adapters, it otherwise reduces fiber connector inventory requirements since now you need to stock one type of connector only. Another advantage is that fiber adapters can be designed to mate one type of connector to another, which is a...

...Manufacturing Strategy Case 1: Case Analysis of American Connector Company Submitted By: Bikramaditya Sharma (2010H149221) American Connector Co. (ACC), a US supplier of electrical components, has been forced to re-evaluate operations at its plant in Sunnyvale, California, in response to the plans of a Japanese competitor (DJC Corp.) to construct a rival plant in the United States. The essential issue at hand is whether American Connector’s customization manufacturing strategy should be modified or replaced to meet the threat posed by DJC Corp.’s low-cost manufacturing approach. The situation is particularly critical as ACC’s Sunnyvale plant has recently been experiencing rising costs and deteriorating product quality. Consequently, the present analysis will examine the manufacturing strategies of American Connector Co. and DJC Corp. from a SWOT (Strengths, Weaknesses, Opportunities, and Threats) perspective in order to determine the potential impact of JDC’s entry into the US connector market. American Connector Company Mass Customization Manufacturing Strategy • Strengths DJC Corporation Product-Focused Manufacturing Strategy • • • ACC’s Sunnyvale plant produces a large variety (4,500) of connectors.

...Connector Installations * Strip the cable of its protective outside jacket about 3-6 inches from the end. This can be done with the cabling scissors by applying pressure from the scissors to the cable and rotating the scissors around the cable. After you have punctured the cables jacket, you should be able pull the jacket off easily leaving exposed wires. * Expose the wire a little further. Stripping the cable can cut and damage the wires at the area that we cut the cable so we want to expose about 6 more inches of fresh wires. Most twisted pair cables have a small string inside the cable to assist with this. * If your cable has the small string. Cut the string after you have enough exposed cable. * Untwist the wires completely to the jacket. Place the wires into the appropriate color slot on the jack. Make sure to place the wires as tightly as possible in the slots in regards to the jacket. There should be as little exposed and untwisted wire as possible to keep the signal strength as high as possible. Make sure to place the White/Blue in the White/Blue spot and not the solid Blue spot. The White/Color wire is not the same as the solid color. * Terminate each wire. After all the wires are in the correct spot and double checked to make sure as little amount of exposed wires will be left as possible, use the punch down tool with the 110 blade and terminate each wire individually. The 110 blade will fully cover the wire connector on the jack. Push down until...

...NT1310 Unit 6 Exercise 1 Luz Garcia 7/22/14 Connector Installations Twisted-pair cable: Step 1: Measure the cable you want to put ends on and trim it to the proper length using the cable cutter. Step 2: Use the cable stripper to strip about 1.5" of the jacket from the end of the cable. Then, rotate the stripper around the cable twice. This will cut through the jacket. Step 3: Remove the stripper from the cable and pull the trimmed jacket from the cable, exposing the inner conductors. If a jacket slitting cord (usually a white thread) is present, separate it from the conductors and trim it back to the edge of the jacket. Step 4: Untwist all the inner conductor pairs and spread them apart so that you can see each individual conductor. Step 5: Line up the individual conductors so that the color code matches the color-coding standard you are using. Step 6: This step includes two points. First, trim the conductors so that the ends are even with each other, making sure that the jacket of the cable will be inside the connector. Second, the total length of exposed connectors after trimming should be no longer than 0.5" to 0.625". Step 7: Insert the conductors in the connector, ensuring that all conductors line up properly with the pins as they were in the previous step. If they don't line up, pull them out and line up. Do this carefully, as it's the...

...Jonathan Hunt 7/23/14 Unit 6 Assignment 1 Cable Testers After installing cables in a building it is necessary to test them to make sure they are functional and did not get damaged during the install. There are many tools that can be used for testing cables, the type of cable that you are working with will determine the kind of tester that you will need. When working with copper cables one of the tools you can use is a tone generator, this tool can be used to test cables for crossovers, and shorts. This tool is most commonly used for testing punch down blocks in telecommunication lines. Another tool that is handy for copper wires is a wire map tester. You can use this tool to send a signal down the cable and make sure that the pin connections on both sides are correct. This tool can also detect a short in a wire as well as openings in the line. This is a fairly inexpensive tool and would be a good one to include in your kit if you are installing cables. Continuity testers can also be used in place of a wire map tester and are also inexpensive. It would be recommended to have at least one of these tools in your toolkit. Personally I would choose the wire map tester. If you are working with fiber optic cables you need to have a completely different set of tools because you are now dealing with light transmission as opposed to electrical current. Fiber optic power meters are used to detect the strength of light going down the cable. Depending on the type of fiber that...

Connector 2001 Case

...MKTG 4120 Case Study – Positioning the ConneCtor 2011 Prepared by LI Danyang Sunny 1155002138 Question 1: Two dimensions were applied in this case since the third dimension did not capture significant variance compared with the sum of first two. (See Figure 1) The variance explained by the horizontal dimension (46.6%) was two times more than the vertical horizontal (20.8%), so the horizontal dimension was more than twice important in explaining customer perceptions than the vertical one. The horizontal axis associated mostly with attributes “Multimedia”, “Stylish” and “Monitor” while the vertical axis associated mostly with “Sturdiness”, “Light Weight” and “Connectivity”. (See Figure 2) From the perception map, Connector 10L performed the best in terms of Connectivity, Data Entry and Third Party Support. Moreover, it also had advantages on its weight. However, Connector 10L was not attractive enough to customers in terms of Multimedia Function, Stylish and Monitor Quality. It is noticed that there was a lack of other brands near Connector 10L’s position (Only Palm VII), which indicated a potential opportunity for new positioning – wireless access feature. (See Figure 2) Question 2: In the positioning map with Preference Vector, it could be found that Connector 10L is the 5th preferred brand chosen by participants, ranked after HP Jornada, Casio Cassuioeia, Compaq IPac and Palm VII.

Ports and Connectors

...Edgar Pixtun NT1110 Ports and Connectors There are many ports and connectors to a computer. The ports are; Serial, Parallel, and Game Ports. A serial port transfers 1 bit of data at a time and is a male port that has 9 or 25 pins, where as a parallel port transfers 8 bits at a time and is a female port with 25 pins, and a game port is a female port as well that has 15 pins laid out in 2 rows. Most computers have now replaced these with USB ports. There are two different USB (Universal Serial Bus) ports. USB port 1, transfers 12 Mbps and is 3 meters wide. USB port 2, transfers 480Mbps and is 5 meters wide. USB connectors come in two sizes, A-connector, and a B-connector, which is the smaller connector. A mouse and keyboard both use a PS/2 port but are now using a USB port wireless. USB can have a limit of 127 devices plugged in at the same time. NIC (Network Interface Card) converts parallel communication to serial and uses an RJ-45 connector. A Modem connects to the phone line but is the slowest way to connect to the internet. It has a transfer speed of 56kbps but V.92 is quicker and it converts analog into digital. The Modem uses a RJ-11 connector. Computers come with two input/ output connections, VGA that has an analog interface that is a D-type connector that has 15 pins laid out in 3 rows, a DVI that is a digital visual interface, and a S-video that connects to the T.V. and that is round with 4 or 7 pins.

..., particularly in regard to curing time.  In creating and evaluating their fiber optic epoxy formulations, manufacturers rely on a number of tests and measurements that may include Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Storage Modulus, Coefficient of Thermal Expansion (CTE), and Glass Transition Temperature (T/sub g/).  Fiber optic connector epoxy curing schedules are created in large part to minimize curing oven temperature gradients and to achieve uniform T/sub g/, which minimizes outgassing and lessens the degree to which pistoning can occur within the ferrule. (FIS, 2013) To speed curing time, some installers have begun using fiber optic connector curing ovens designed for "hot-melt" style fiber optic connectors, which operate at temperatures that are 100 to 200 degrees higher than those of epoxy connector curing ovens. This practice violates the epoxy manufacturer's curing instructions and can cause a multitude of problems. These problems range from degraded fiber optic connector performance to complete failure of the optical connection.  * Heat Cure Vs. Room Cure Connector Epoxy When using an epoxy style fiber optic connector, one must decide which type of fiber optic connector epoxy is preferable for the task at hand, namely a "heat cure" epoxy or a "room cure" epoxy. The following are some advantages and disadvantages of both. * Heat Cure Fiber Optic Connector Epoxy Heat Cure fiber optic connector epoxies require...
