Essay Essay THE MOST MEMORIABLE VACATION My most memorable vacation was when I went to NHA TRANG with my family last summer. When my father told me I was excited because NHA TRANG famous for beautiful beaches and delicious foods. After four hours on the train, finally we arrived. Although I felt tired after long hours, I am happy when I was standing in front of a beautiful beach. Firstly, we arranged our bags and after that, we quickly swim in the blue sea. Next, my younger brother and I were building sandcastles while my parents were sunbathing on the sand. For a few hours, we felt hungry so we went to a nearby restaurant to enjoy tasty foods. In the afternoon, we visited some beautiful and famous places such as THAP BA PONAGAR; HON CHONG then went to NHA TRANG center to buy some souvenirs. The day went by so fast. The trip was short but it had a strong impression on me and my family and I have many memories of that day. QUALITY OF A GOOD TEACHER The good teacher has three important qualities. The first quality of a good teacher is that having strong knowledge of his or her subject matter. For instance, teachers have to provide students with specific content knowledge. A good teacher will know how to explain the content that he or she is teaching in a way easy to the most understand for students. Another quality of a good teacher is enthusiastic and caring. For example, he or she always cares academic status of the students and help them more advance in learning. Moreover, they also learn about the family circumstances of the individual students and find ways to help the poor students. The last quality is that confidence. Standing in front of a class, he or she has to the voice clear and full of confidence to their student pay attention to his or her lectures. To sum up, a good teacher need to have three qualities above and ethic good quality. DISADVANTAGES OF LIVING IN THE DOMITORY Living in a college dormitory has several disadvantages. The first disadvantage is narrow space. For example, dormitory in PHU YEN University, there are eight students sharing the room, it becomes crowded and narrow. You do not have much space to learn within a dorm. In addition, your  roommates can be messy, upset, or talkative so you will feel uncomfortable when living together with them. Another disadvantage is food. You are not allowed to cook in the dormitory so you have to eat rice at the canteen or at the restaurant. The amount you have to pay for meals in the dorm expensive than in the motel. In addition, you will feel tired of when you have to eat the same foods every day. Finally, living in a dormitory is noisy. Sometime you cannot concentrate for learn if your roommate opens music loudly. To sum up, you must find the best accommodation for you to convenient for your learning but you should think before deciding to live in the dormitory. A BEAUTIFUL BEACH AT DAWN Beyond a shadow of doubt, NHA TRANG beach is one of the most beautiful beaches in Vietnam, particularly at dawn. Every day, at 5.30pm, the sunrise slowly, it is like yolk rise from the bottom of the sea. At that time, the beach always crowded. Many people get together here very early to do the exercise and bathe in the sea. The beach scenery at dawn is fantastic, with a neglected beauty. The silence covers the whole beach; there is no sound but the sound of breaking waves. If you stand on the sandbank and stare into the distance, in the sun direction, you will have a strange feeling; have something peaceful in the deep of your soul. The atmosphere is so great by the winds, which come from. When the sun has risen completely, you can see some light rays of sunlight; they signal to you that the dawn-time nearly ended. I think words cannot describe how nice this beach is at dawn. If you have a chance to visit somewhere, why do not you try visiting NHA TRANG to enjoy the beach landscape at dawn in the true sense of the word? A BEAUTIFUL BEACH AT DUSK Sitting on the fine sand, I can see the amazing beauty of the beach at dusk. The sun like a fiery orb looks like it is gradually receding into the waters below. The setting sun’s red rays lit up the sky above the western horizon. At the time, the sky consisted of an assortment of shades, a blend of reds, oranges, and yellows. The waters below mirror this effect. The waves are tinted vermilion; the sand under my feet is the same color, the vivid color mix highlights the beauty of the beach at dusk like a perfect picture. I can  hear is the sound of the waves as they crash against the shore, and seagulls, which I cannot see, squawking in the distance. Sometime I can smell the fishy smell of fish. It smells warm and salty, as I breathe in the cold, salty. I just stand there, eyes closed, and feel the moment until the dusk and the warm feeling fades. I wish time could stop to enjoy this wonderful moment longer. HOW TO MAKE CHICKEN RICE You can make a tasty chicken rice dish if you follow these easy steps. The first step is to prepare the necessary ingredient such as haft chicken, rice, three slices ginger, salt, coriander onions, cucumbers, tomatoes, and chilly sauce. Next, cook the rice in the rice cooker. The third step is to cut the chicken into bite-sized pieces, and then combine all the other ingredients and mix well in a bowl. After that, pour the mixture over the chicken, cover with foil and bake until the rice is cooked. When the rice is cooked, season to taste with salt, if needed. Finally, scoop a bowl of chicken rice on plate. Place cooked chicken over the rice. Garnish with sliced cucumbers, tomatoes, coriander, and spring onions. Now sit down and enjoy your delicious chicken rice plate with ginger sauce and chilly sauce on the side. HOW TO PREPARE FOR A JOB INTERVIEW Before a job interview, you can be stressful, but you can reduce your stress by following these skills. The first skill is picking out what you are going to wear to your job interview. The first choice an interviewer makes is going to base on how you look and what you are wearing. That is why it is always important to dress appropriately for a job interview. The second skill is that practiced greeting before your interviewer. You should always greet your interviewer with a friendly smile and a firm handshake. It will create a good impression about you to the interviewer. Next, you should prepare some typical interview questions you will probably be asked during a job interview. If you prepare well the answers of the interviewers can ask, you will not be surprised with questions about them. Practice interviewing  with a friend or family member ahead of time and it will be much easier when you are actually in a job interview. To sum up, the interviewers will appreciate what you did and can choice if you have a good preparation. AUSTRALIAN AND VIETNAMESE EDUCATION SYSTEM Australian and Vietnamese have similarities and differences in the education system. We can see that both education systems of Australian and Vietnam are quite similar that they have twelve grades, from one to twelve. In addition, schooling is compulsory for students until the age of fifteen. Despite the similarities, the two educations have some very important differences in system division, school-time. The first major difference between Vietnamese and Australian education is the system division. In Australia, primary school goes from grade one to six and secondary school from grade seven to twelve. In Vietnam, we have primary school (from grade one to five), middle school (from grade six to nine), and high school (from grade ten to twelve). Another obvious difference that we can see from these two educations is school-time. In Australian, the academic year begins in early February for school students and late February/early March for vocational and university students. However, in Vietnamese, the academic year begins in middle August for students and late August/ early September for university students. Although both education systems of Australian and Vietnamese have a lot of differences and similarities, they are good education systems for students. AMERICAN AND VIETNAMESE MEALS American and Vietnamese meals are quite different. One difference is Americans have one big dinner per day but Vietnamese have three meals a day with some snacking on fruits and cakes. Americans always think to take advantage of that time to be effective, breakfast and lunch only eating briefly, in the evening with more spare time, so comfortable chatting happily, and eating dinner together. Another difference is that the Vietnamese have breakfast with soup â€Å"pho,† rice or rice noodles; bean sprouts; greens; boiled eggs; and crusty bread and drink green tea or coffee. The Vietnamese have lunch and dinner with rice, fish, or meat;  vegetable dish with fish sauce then snacks with fruits or cakes. In contrast, Americans eat many foods that are high in calories and fat, such as hamburger, fried chicken, sandwiches. They do not spend much time in preparing food so they choose fast foods or going to the restaurant to eat. All in all, though there are differences between American meal and Vietnamese meal, they are typical culturally in the world.

Transducers used in the Cardiac Ultrasound Machine.

Transducers used in the Cardiac Ultrasound Machine. Transducers used in the Cardiac Ultrasound Machine. Abstract: Ultrasound imaging depends on the ability of piezoelectric crystals to generate sound when excited with alternating current and the reverse effect of charge accumulation or current flow when such crystals are subjected to pressure from sound waves. The first known ultrasound imaging machine was designed by K. T. Dussik in Australia in 1937. However, despite its widespread acceptance today, medical ultrasound did not develop as rapidly as X-ray imaging. Despite the relatively slow start, medical ultrasound imaging is very widely accepted today because there is no ionising radiation involved and hence the procedure is relatively safe. Ultrasound equipment is also cheaper as compared to X-ray imaging, magnetic resonance imaging, MRI and other techniques associated with nuclear medicine. The procedure involves minimal patient discomfort and is very useful for examining the soft tissues or the developing foetus. A dramatic increase in the number of older patients with chronic he art and valve disease has resulted in a prolific demand for the ultrasound cardiac imaging machines which can satisfy the requirements associated with fast and cost effective measurement of cardiac anatomy or function. One of the critical elements in the medical ultrasound imaging system is the ultrasound transducer without which signal processing and visualisation of the soft tissue images is impossible. Although many naturally occurring substances such as quartz exhibit the piezoelectric effect, lead zirconate titanate (PZT) ceramic ferroelectric materials have for many years been used for biomedical applications because of their superior characteristics for soft tissue imaging.   Polyvinylidene difluoride (PVDF), transducer material has demonstrated advantages as a high frequency receiver. Single or multilayer transducers made of these elements can be used for ultrasound imaging as single transducers operating in A-mode or a two or three dimensional transducer array for B-mode, C-mode or M-mode ultrasound imaging. This brief essay takes a look at transducers for medical ultrasound. The principle of operation of a cardiac ultrasound imaging device is based on the information that is provided by the varying delay times of echoes that are reflected from various depths of the human body tissue as a result of the ultrasound pulses that are generated by an ultrasound transducer being incident on the body tissue. Delay times of echoes from different depths are different and ultrasound is reflected from the interface of different types of tissues. A Doppler shift in frequency is also generated as a result of moving objects and the attenuation of ultrasound waves depends on the type of tissue that the ultrasound wave is travelling through. The ultrasound transducer which is responsible for the generation and detection of reflected ultrasound is, therefore, an essential component of the ultrasound imaging device. Ultrasound transducers work on the basis of the piezoelectric effect in which an alternating voltage applied to piezoelectric crystal material causes the crysta ls to become electrically polarised as a result of the applied electric field and hence vibrate with the alternating voltage to produce sound. Such crystals also become electrically polarised when stress is applied to them and hence any sound waves which are incident on them result in charge accumulation on the crystal surface and hence the generation of an alternating voltage. Thus, an ultrasound transducer consists of a suitable piezoelectric material sandwiched between electrodes that are used to provide a fluctuating electric field when the transducer is required to generate ultrasound. When the transducer is required to detect ultrasound, the electrodes may be used to detect any fluctuating voltages produced as a result of the polarisation of the crystals of the piezoelectric material in response to incident sound which generates fluctuating mechanical stresses on the material. Piezoelectric materials include quartz, ferroelectric crystals such as tourmaline and Rochelle salt a s well as the group of materials known as the piezoelectric ceramics, which include lead titanate (PbTiO3) and lead zirconate (PbZrO3). These materials are also known as piezoelectric ceramics which are used in ultrasound transducers for biomedical applications.Polyvinylidene difluoride (PVDF) is another transducer material which has demonstrated advantages as a high frequency receiver. Piezoelectric ceramics are sold with the brand name PXE by Philips Company and are solid solutions of lead titanate (PbTiO3), and lead zirconate (PbZrO3) which have been modified by additives which are a group of piezoelectric ceramics known as PZT. PXE materials are hard, chemically inert and unaffected by a humid environment. The crystals in a ferroelectric material of which PXE is made up of align themselves randomly in a number of directions. With such a random orientation of crystals, the material will exhibit no piezoelectric effect. In order to have a piezoelectric material which is capable of being used for ultrasound transducers, the material has to be subjected to a strong electric field at high temperatures. This has the effect of permanently locking the crystals in the direction of the applied electric field and making the crystal piezoelectric in the direction of the electric field. Hence, a piezoelectric ceramic material may be converted into a piezoelectric material in any given direction by applying a strong electric field to the material in the given direction at an elevated temperature. This treatment, which is known as poling, is the final stage in the manufacture of a PXE piezoelectric. Metal electrodes perpendicular to the poling axis are deposited on the material so that an alternating electric field may be applied to generate ultrasound or ultrasound vibrations may be sensed by sensing the electric field across the piezoelectric material. The voltage across a piezoelectric ceramic PXE material is usually directly proportional to the applied stress. The construction of a simple, single element piezoelectric transducer is as shown below. The Construction of a Single Element Piezoelectric Transducer Ultrasound imaging in the A-mode directs a narrow beam of ultrasound into the tissue being scanned and the echo which may be displayed on a CRT screen provides a measure of the distance between reflecting surfaces in the body. In the B-scan mode, the echo signal is brightness modulated which makes it possible for information related to tissue depth to be displayed on the screen in a visually effective manner. An ultrasound transducer array operating in B-mode permits a picture of the tissues within a patient’s body to be displayed on a CRT device. M-mode ultrasound imaging presents tissue movement by scanning an A or B – line on a monitor as a function of time and movements in this line indicate movements in the tissues within the body. In C-mode ultrasound imaging a second transducer is used to detect echoes sent out by the first transducer, presenting a 2-D map of the ultrasound attenuation within tissues. Having discussed the principles of operation of a piezoelectric medical ultrasound transducer, it is now appropriate to consider the practical problems associated with the construction of such transducers. This is done below. The Design of Ultrasound Transducers A transducer which is constructed out of piezoelectric material will have a natural frequency of resonance and it is appropriate that the transducer should be excited with alternating electric field which matches the natural resonant frequency of oscillation of the material. The ultrasound frequencies that are used in medical imaging applications range from 1 MHz to 15 MHz and echocardiography is usually performed at frequencies of 2.5 MHz. Hence, transducers which are used for ultrasound imaging have to be tuned for different frequencies. For a transducer material in which ultrasound waves travel at the speed c, with a resonant frequency f, the thickness of the material is related by the formula f=c/2d. Hence, it is possible to tune various transducers constructed of the same material to different frequencies by adjusting the thickness of the material. The ultrasound transducer can be excited by a continuous wave, a pulsed wave, or a single voltage pulse depending on the requirement s for observing a continuous image, echo ranging or other tissue measurements. The rear face of the piezoelectric crystal material is usually supported by a backing material which is tungsten loaded araldite, so that the vibrations in the piezoelectric material are rapidly damped after the initial excitation. It is important to couple the piezoelectric transducer to the body of a patient so that the incident ultrasound energy can be effectively transmitted into the body tissue that is being scanned. In order to do this, matching layers of suitable acoustic material are used along with a gel which makes it possible for the ultrasound waves to penetrate the tissue more efficiently. As far as possible, the characteristic acoustic impedance of the tissue being scanned is matched with the acoustic impedance of the transducer. The characteristic acoustic impedance of the tissue is defined as: In the formula, c is the speed of ultrasound in human tissue which is about 1540 m/sec with a variation of +/- 6% and   is the tissue density. K is the bulk elastic modulus of the tissue being scanned. The acoustic parameters of an ultrasound transducer include its nominal frequency, the peak frequency which is the highest frequency response measured from the frequency spectrum, the bandwidth of the transducer which is the difference between the highest and the lowest – 6 dB level in the frequency spectrum, the pulse width response time of the transducer, which is the time duration of the time domain envelope which is 20 dB above the rising and decaying cycles of a transducer response, the loop sensitivity for a medium on which a test is performed which is characterised by: Here, Vo is the excitation pulse voltage in volts, while Vx is the received signal voltage from the transducer.   The signal to noise ratio for a biomedical ultrasound transducer is also an important parameter for an ultrasound transducer and this is defined as: In the above expression, Vx is the received signal voltage from the transducer in volts in response to a specified tone burst or pulse and Vn is the noise floor in volts. The signal to noise ratio for an ultrasound transducer is a measure of the noise associated with the transducer, measuring instrument or cables and this is a good measure of how sensitive a transducer is. In addition to the previously mentioned parameters, geometrical parameters for a transducer describe how the acoustic pressure generated by a transducer varies across the axial and cross-sectional fields of a transducer. These variations are illustrated below: Axial Beam Profile for an Ultrasound Transducer Cross – Sectional Beam Profile for an Ultrasound Transducer he detailed construction of an ultrasound transducer for medical applications involving the shaping of the piezoelectric material, matching layers, housing and backing materials etc is presently conducted using computational techniques such as Finite Element Modelling of ultrasound transducers through the use of software packages such as Ultrasim and other commercially available software. In the overall design, efforts have to be made to ensure that the overall design will be optimised so as to deliver a sufficiently high power of ultrasound into the tissue being imaged and as far as possible there is best possible sound impedance matching between the transducer and the scanned tissue. Design of the backing material in an ultrasound transducer is important because this design determines the ring down time of the transducer, which is critical for low noise and optimal axial resolution of the transducer. Trends in Transducer Design for Echocardiography Only the simplest equipment for echocardiography will use a single ultrasound transducer and there is a trend towards design of echocardiography equipment which uses two or even three dimensional arrays of ultrasound transducers to provide superior quality 2 –D or 3-D computer generated pictures of the organ being imaged.   Even the relatively simpler equipment being used these days has two or more ultrasound transducers fitted into the transducer probe. The array of transducers are capable of generating a shaped beam of ultrasound which can be appropriately focused using electronic digital signal processing techniques to provide better images and resolution. Although the relatively simple medical ultrasound scanners cost about  £1000 per piece, reasonably decent transducer assemblies for a decent Philips or Toshiba ultrasound machines can cost  £1500 for the transducer alone. Transducer arrays for two or three dimensional ultrasound imaging equipment can be much more ex pensive because of the large number of transducers that are employed in such imaging equipment.   For better quality ultrasonic imaging to be possible, there is a requirement for enhanced bandwidth transducers, higher frequency transducer arrays and sophisticated digital signal processing circuits. There is also a trend towards transducer miniaturisation which will make intracavitary, intraurethral, or intravascular ultrasound (IVUS) investigation possible. The current imaging frequency range of 1 MHz to 15 MHz is expected to be increased to 20 MHz to 100 MHz and at these frequencies, microsonography devices using miniature ultrasound transducers with higher sensitivities are expected to provide much better and higher resolution images using catheter based transducers which are less then 2mm in diameter and are capable of being placed in veins.   New ultrasound transducer materials are likely to provide transducers which are far more sensitive then those available presently and consume lower power. These transducers can be operated from battery powered portable equipment and th ere are indications in literature that with the availability of such devices, it is likely that the stethoscope will be replaced by miniature ultrasound equipment. New trends in ultrasound transducer construction are also moving towards composite transducer construction in which a composite of two piezoelectric materials is used to design the transducer. Ultrasound transducers are fairly rugged and the piezoelectric material does not loose its properties unless exposed to high temperatures approaching the Curie temperature for the material are reached or there are strong alternating or direct electrical fields opposing the direction of poling for the material. Mechanical stresses imposed on the piezoelectric materials should not exceed the specified limits and although the specified limits vary for different types of materials, mechanical stress in excess of 2.5 MPa may be considered as likely to cause permanent damage. Ultrasound transducers are capable of being designed to operate in liquid mediums and the piezoelectric material does not react with water or gel.   Conclusion Materials with piezoelectric properties such as lead titanate (PbTiO3) and lead zirconate (PbZrO3) lend themselves to being treated by poling to generate as well as detect ultrasound waves when subjected to alternating electric fields or mechanical stresses. Ultrasound transducers can be made out of these materials and these transducers can be designed for specified resonance frequencies for use in medical imaging. The detailed design of such transducers is an exciting and involving undertaking which is capable of being assisted by finite element simulations. Advances in transducer design involving the use of new materials, miniaturisation and the use of arrays of transducers promises to revolutionise medical imaging in the future by providing high resolution 3-D ultrasound images and the field is full of promise for device designers as well as computer engineers of the future.

black history Riggie White :: essays research papers

Riggie White Minister of Defense Riggie White was not only an outstanding Football player but also a well-established Minister. He had many outstanding achievements during his foot ball career. He has also done a lot for the church. So white was a well-rounded leader in the African American Community. After an All-American senior season at Tennessee, White began his pro career with the Memphis Showboats of the USFL in 1984. He joined the Philadelphia Eagles, who held his NFL rights, after the USFL folded in 1985. For eight years, he played a major role in Philadelphia's "Gang Green Defense." Which seem to be unstoppable at this time. White signed as a free agent with Green Bay in 1993 for $17 million over four years. His signing, along with a trade for Favre, helped make the Packers champions again. He was the first major black player to sign with the Packers as a free agent. With this decision he made surprised many b/c he want to be in a large city where he could minister to young black youth. While with the Packers White and the team made consecutive appearances to the Super Bowl where in 1997 with a win over New England White set a record with three sacks. White was 39 when he finished his NFL career with Carolina, leaving the game with 198 sacks. That was actually White's third retirement. He retired for one day before the 1998 season, but then said God had told him he needed to play again, and he returned to the Packers. White retired again after the 1998 season and took a year off from football. After the Packers allowed him out of his contract, White returned to play for the Panthers where he finished his football career. White worked tirelessly in the off season with inner-city youth. But his image was tarnished when he gave a speech to the Wisconsin Legislature in which he denounced homosexuality and used ethnic stereotypes. White later apologized for any harm his comments may have caused. He put his fame and star powers to less controversial use in 1996 after his Tennessee church was burned down.

An Interpretation of the Ghost :: science

An Interpretation of the Ghost Ghost is something that some believe and some won't. But still most of them get frighten to some extend, when they watch terrific horror films. Perhaps it is due to the terrific sounds or special effects that imposes ones mind. But there is a specific science that has the ability to explain the concepts of the spirits or ghosts called Adhyathma (A study centered around the soul)in the Ancient Indian script. According to the teachings of the ancient scripture Bhagavad Gita, the brain (and the body in general) is only a mechanical device used by the spirit soul (the actual self). It is described that just as a passenger rides in a chariot, in the same way the spirit soul is riding in this vehicle of the body. The scriptures state that one who commits suicide will have to remain as a ghost for the period of time that one's body was supposed to exist. A ghost is nothing but a person with no physical body. According to the sankhya system, our body is made up of two coverings, the sukshma-sharira (subtle body) and the sthula-sharira (gross body). The gross body is made up of the panca-bhutas (earth, water, fire, air and ether), and the subtle body is made up of the mind (manas), intelligence (buddhi) and identification (ahankara). It is the subtle body which accompanies the soul into the next body at the time of death. The gross physical body has a particular duration of existence based on one's prarabdha karma(results of the deeds of his previous incarnation).When one commits suicide, one brings one's physical body to an end prior to it having completed it's allotted time. One's next body is prepared in the akasha (ether), ready to manifest at the end of one's allotted time (the normal death of one's physical body). Thus if one was supposed to live for 100 years, one's next body will be waiting for you after that 100 years. If for some reason one were to commit suicide at the age of 50, then one's next body will not be ready, and one will remain in an ethereal state until the balance 50 years of existence pass. This state of existing as a ghost is a great suffering for the individual, as they lack the senses through which to act. The desires to act remain, as the mind, intelligence and identification of the subtle body are still existing.

A room of ones own Essay -- Literary Analysis, Virginia Woolf

Virginia Woolf's ambitious work A Room of One's Own tackles many significant issues concerning the history and culture of women's writing, and attempts to document the conditions which women have had to endure in order to write, juxtaposing these with her vision of ideal conditions for the creation of literature. Woolf's extended essay has endured and proved itself to be a viable, pioneering feminist piece of work, but the broad range of ideas and arguments Woolf explores leaves her piece open to criticism over certain concepts which seem to contradict themselves. This observation can be explained most satisfactorily by critic Ellen Bayuk Rosenman, who posits, "the essay does not strive for the strict coherence of a jigsaw puzzle, composed of perfectly interlocking pieces in which no gaps exist and there is nothing left over...Woolf's essay has proved so durable because it often contradicts itself"(13). Woolf puts forth the notion in the end of her essay that the "androgynous mind" i s to be the apotheosis of all the perspectives of writing; yet this belief she conveys contradicts not only previous evidence she has expressed but also diminishes the value of the female as a significant contributor to the world of literature, and discredits woman's ability to write as she is attempting to praise and inspire us. Virginia Woolf uses A Room of One's Own as a platform to discuss past and current social inequities that exist within the realm of women and literature, attempting to document the negative effects that patriarchal society of the early twentieth century England has wrought upon the female psyche. From her analysis of these issues and her own life experiences, Woolf comes to the conclusion which becomes the basis for this essay... ...(13), exposes brilliantly the ambiguity present throughout Woolf's essay. And Woolf herself provides the most eloquent contradiction of the piece when she urges, "it is much more important to be oneself than anything else. Do not dream of influencing other people, I would say, if I knew how to make it sound exalted. Think of things in themselves"(2211). To 'think of things in themselves' in the most literal sense would be to allow every perception, every attitude, every emotion equal stature in one's mind and in the writing process. Perhaps it is not disregarding one's own sex that will make for the highest form of literature, but instead allowing the combination of experience and emotion, spirituality and materialism, belief and conjecture, to coalesce into a beautiful mass of ideas that will truly be a reflection of the author in her most complete consciousness.

Challenges Facing Fashion Industry in Ghana

CHAPTER ONE BACKGROUND TO THE STUDY The environment in which the fashion industry operates the world over has become turbulent, unpredictable and therefore, difficult to exert managerial control. Cultures around the world are constantly influencing each other; hence, the world’s cultures are changing fashion constantly. Also, social, economic, political and legal factors keep changing than before. Competition in the fashion industry is so rife such that the survival of fashion organizations cannot be guaranteed (Stuart, 1995). During the last decade, the developments of new technologies all over the world and growing globalization of countries economies have produced the fastest changes ever. The fashion industry in Ghana, especially, the clothing sub sector (which is the focus of this study) has not been without the effect of economic, political, social, cultural and legal pressures brought to bear on all organizations. In recent years, protectionism has given way to globalization. With that change, Ghanaian clothing sector of the fashion industry has had to compete with imports from low wage countries. Retailers, unencumbered by protectionism, have also seized on the opportunity, often choosing to go directly to offshore manufacturers. As retailers become larger and more globally connected, they continue to build global brands marketed around the world. In doing so, they eliminate many Ghanaian clothing companies from their supply chain. The result has been major market share declines and job losses in the industry. Aug The Ghanaian clothing sector of the fashion industry faces many challenges. he rise of low-cost goods from Asia, a slowdown in consumer spending, difficulty in accessing capital, lack of innovation from entrepreneurs, relatively high prices of products due to high unit cost, poor distribution channels and inability to promote local brands. It is without doubt that low-cost Chinese imports have increasingly dominated the local fashion scene. As a result some local manufacturers, in an attempt to remain competitive, have subcontracted their production processes offsho re. The issue of access to capital for the industry is not new. For years, industry players have indicated that they feel there is a lack of support for their industry from the banking community. Under these circumstances, it is not a surprise that many companies cannot secure financing. as a result of banking formula-based lending practices, financing remains a challenge to many well-run clothing companies and small businesses in general. Brand DEVELOPMENT HAS BEEN A MJOR ISSUE IN THE clothing sub sector in the fashion industry in Ghana. Many Designers have not been able to design unique Ghanaian designs that would bear their own brand name in order to project their business. However, a few creative ones have had their product design copied wrongly and produced cheaply from China, thereby destroying the brands they have developed. These and other factors have created serious marketing challenges for the clothing sub sector of the fashion industry in Ghana. This study would go into detail to look at the nature of the marketing challenges facing the industry in Ghana. STATEMENT OF THE PROBLEM There are growing signs Ghanaian garment and fashion industry is approaching a serious crossroad. Increasing numbers of mainland Chinese manufacturers are taking Ghana’s role of mass-producing quality fashion items at reasonable cost. Industry players, also have difficulty securing financing from other lenders. For example, asset based lenders often require substantial premium interest rates. Other larger non-traditional lending institutions and professionals that can assist prefer working with larger companies where greater fees and returns can be earned. The traditional financing problems will likely become further exacerbated as companies implement new models that do not generate assets that can be collateralized. The problems enumerated above, as well as western cultures, globalization have created internal marketing challenges for the clothing industry in the area of promotion, pricing and distribution of products. The study seeks to unravel the challenges and make recommendations to solve the problems. OBJECTIVES OF THE STUDY The objectives of the study were: 1. To investigate how foreign cultures have influenced the Ghanaian brands in the clothing industry. 2. To assess the challenges associated with clothing design ( product development) 3. To investigate the challenges industry players face in their pricing of products . To assess how they promote their products. RELEVANCE OF THE STUDY It is hoped that the study would benefit clothing sub sector of the fashion industry in Ghana. Also, it will serve as a pedestal upon which future researches in the area would be based. CHAPTER TWO LITERATURE REVIEW Eusebio (2007) carried out a research on the topic â€Å"Internal key factors in export pe rformance: A comparative analysis in the Italian and Spanish textile-clothing sector† The purpose of this paper is to analyze the key factors in the international performance of textile manufacturing companies. The study provided a comparative study of the main factors that have affected the export performance of the Spanish and Italian clothing sub sector of the fashion businesses. A wide range of factors has been studied, such as size, dispersion of sales and export experience. In order to compare Spanish and Italian cases, the empirical study used a standardized questionnaire for collecting data. The cases analyzed were respective geographical zones with a great tradition in textile-clothing industry in their country, Catalonian (in the Spanish case) and Lombardian business (in the Italian case). It was found that international experience was the main factor in the export performance for both cases but the investment in R&D and the export experience have been the keys for explaining the major export performance of the Italian businesses. The paper explained why the Lambardian textile-clothing companies exported more, in relation to total sales, than the Catalan companies in the same sector. . Research limitations – The sample was formed basically for small textile-clothing businesses (with less than five employees). Eusebio (2007) STUDIED Top of Form Management perception and marketing strategy in export performance: A comparative analysis in Italian and Spanish textile-clothing sector The purpose of the study was to focus on the key factors in the international performance of textile manufacturing companies. In order to compare Spanish and Italian cases, the empirical study used a standardized questionnaire for collecting data. The cases analysed were respectively geographical zones with a great tradition in textile-clothing industry in their country, Catalonian (in the Spanish case) and Lombardian business (in the Italian case). Research limitations/implications – The sample was basically from small textile-clothing business (with less than 500 employees). It was found that international experience was the main factor in the export performance for both cases but investments in R&D and export experience have been the keys for explaining the major export performance of the Italian businesses. The study was of value in that it provides a comparative study of the main factors that have affected the export performance of the Spanish and Italian businesses. A wide range of factors has been studied, including characteristics of the business, such as size, dispersion of sales and export experience. Freeman (2007) carried out a survey on the topic â€Å"Fashion marketing to women in Kazakhstan†The purpose study was to explore consumer behavior regarding women's decisions concerning fashion in the emerging marketing of Kazakhstan. Literature review formed the basis of the questions asked to several focus groups and in-depth interviews of 48 Kazakhs representing the average age of Kazakhstan. The approach of the paper was exploratory as there was not a lot of research concerning the Kazakhstani marketplace. The work revealed that Kazakhstani women were becoming aware of their rights to choose clothing and location of purchase. They expected to be treated with respect. The women were value conscious, thinking brand names enhanced the value of clothing and will shop sales regardless of the actual discount. Kazakhstani women we extremely fashion conscious and looked to the media current fashions. They were wary ything coming out of China. There were five market segments into which these women can be divided. Practical implications – Kazakhstan is opening as a marketplace. In order to understand how to market in Kazakhstan, firms must understand what is wanted and this paper begins this exploration. This market is unexplored both academically and by many clothing manufacturers. This market is opening and thus information concerning the marketplace is necessary. Chong (2007) carried out a survey on the topic â€Å"Central and Eastern European countries and North Africa: The emerging clothing supplying countries to the EU†. The purpose of this study was to examine the delocalization trend of the EU's clothing production to Central and Eastern European Countries (CEECs) and North Africa, focusing on the geographical shift of outsourced clothing production pattern within the two developing regions. In total, 14 CEECs and North African countries were selected and classified into 1st-tier and 2nd-tier regions according to their GDP/capita values. Clothing trade statistics were obtained from the Eurostat database, and the clothing trade pattern was examined during 1995 to 2004. Trade Specialization Coefficient (TSC) was employed to measure the international competitiveness of clothing exports of the selected CEECs and North African countries. Results concluded that the EU's clothing production had significantly delocalized to the proximate CEECs and North African regions, with further geographical shift to less-developing 2nd-tier clothing supplying countries in recent years. The TSC analysis reflected that the competitiveness of clothing industry in 2nd-tiers had outperformed the 1st-tier economies, indicating Western European firms had shifted their sourcing practices to those lower-waged countries. Koksal (2007) studied on the topic† references regarding children's clothing in Turkey† The aim of this study was to determine the factors affecting the consumer preferences and behavior in the children's clothing market in Turkey, a country where the majority of the population is under 18 years old. Whilst the study investigated the purchasing preferences and behaviour of parents, such as shopping frequency and period, type of retailer and the effect of reference groups in the children's clothing market, it also explored some children's purchasing characteristics, like shopping decision age. This study offered some academic results on consumer behaviour and preferences in the children's clothing market: There is no set shopping period; consumers prefer shopping from independent shops; in the selection of retailers, consumers consider payment conditions, pricing, and range of merchandise; in the family the parents mostly make the buying decisions for their children's clothes; the age of children making their own clothing decisions varies between six and ten; the most important factors affecting consumers' decisions towards shopping for children's clothing are the price, quality, convenience, payment conditions, and size of the clothing. Kilduff (2007) carried out a research on the topic â€Å"Analysis of comparative advantage in the textile complex: A study of Eastern European and former Soviet Union nations† This research aimed to present an exploratory investigation into ten-year (1995-2004) patterns of trade specialization among Eastern European and former Sovie t Union Nations, assessing patterns of comparative advantage across the textile machinery, man-made fiber, textile, and apparel sectors of the textile complex to determine whether these conform with both trade specialization and industry evolution theories. A revealed symmetric comparative advantage index was employed to evaluate international competitiveness for 27 Eastern European and former Soviet Union Nations over a ten-year period. A repeated measure ANOVA was used to determine the significance of the observed patterns across four income-defined groups of nations. Overall, the pattern of export development and RSCA generally reflected expectations regarding factor proportions theory and industry evolution models. The RMANOVA partially confirmed the observations. The analysis indicated that income group did not independently affect comparative advantage; however, the nature of products was the significant factor influencing national comparative advantage. According to the researchers, the established models may be better at understanding those nations which have established relatively stable political and economic environment, and been experiencing earlier stages of industry development, but appear less useful in predicting development patterns for those nations experiencing dramatic transitions from regulated to de-regulated markets. The patterns of national comparative advantage in a vertical textile complex are identified for Eastern European and former Soviet Union Nations. The dynamics of change over a ten-year period following economic reforms are revealed. Karpova et al (2007) looked at the topic â€Å"Making sense of the market: An exploration of apparel consumption practices of the Russian consumer†. The purpose of this study was to examine and interpret post-socialist consumer xperiences in relation to clothing consumption practices when consumers shop, acquire, and wear clothing and other fashion-related products. Th e in-depth interview was the primary data collection tool. Data collection was conducted during summer 2004 in St Petersburg, Russia. College students formed the sample for the study. In total, 17 students (four males and 13 females) were interviewed. The hermeneutic approach was used to interpret the meanings of the participant life experiences. In comparison to consumers in an established market-based economy, consumers in this post-socialist market have unique perceptions of clothing attributes (quality, brand name, country of origin, retail channel) critical for buying decisions. Overall, appearance and clothing play a special role in the emerging Russian market as they help construct and communicate new identities more than any other product category. Identified challenges of the Russian apparel market indicate opportunities for domestic and foreign apparel businesses. The meanings Russian consumers attach to clothing attributes can be used to develop product positioning and promotional strategies. Discussed implications of the research findings can be extended to other post-socialist emerging markets. This study explored how Russian consumers have adjusted to the new economic reality after almost fifteen years of transition from a socialist to a capitalist society from the perspective of the consumer. Whereas previous research findings were confirmed, the present study provides rationale for perceived importance of quality and unimportance of brand name in the Russian apparel market. Curran (2007) studied the topic â€Å"clothing's big bang: the impact of the end of the ATC on developing country clothing suppliers†. Prior to the liberalization of the clothing and textiles sector under the Agreement on Textiles and Clothing (ATC) fears had been expressed about the potential impact on developing country suppliers. This study sought to establish the actual impact of the liberalization of the EU and US clothing markets. Comparison of trade figures pre and post liberalization. Was the basis for the research design The research revealed that, as forecast, significant changes occurred in sourcing patterns in the EU almost overnight. The big winners were India and China. Almost all other developing countries lost market share, although often not as much as had been feared. The impact of the liberalization was mitigated somewhat by the new quantitative restrictions negotiated with China half way through the year, which resulted in a redistribution of market share to other developing countries. Comparisons with the USA indicated that trends are rather similar, although on that market more developing countries saw increases in their exports, partly canceling out losses in the EU. Johnson (2007) carried out a survey on â€Å"The role of focal suppliers in strategic networks for internationalization: Perspectives from small and medium-sized Italian and Thai silk suppliers† The purpose of this research was to examine the role of focal suppliers in strategic networks for internationalization from the perspectives of small and medium-sized Italian and Thai silk suppliers. Multiple case studies of small and medium-sized suppliers within the silk industries of Italy and Thailand were undertaken. In total, seventeen interviews and three observations were conducted with directors or managers of silk suppliers and a range of government agencies, associations and institutes involved with the silk industry, to identify significant current issues within the sector. Conceptually clustered and role ordered matrices were used as coding frameworks to reduce, structure and analyze the data. The research showed that Silk suppliers' networks may be co-ordinated by a focal supplier that assumes the role of strategic leader. The involvement of a focal and strategically-focused supplier may strengthen and integrate the resources and capabilities of silk suppliers in their networks and enable them to improve their international network development and position. Further investigation is needed on the details of specific roles of focal suppliers in strategic networks. In the view of the researchers, Silk suppliers, their customers and government agencies involved with silk suppliers should: advocate and actively support the development of focal suppliers in their networks to enhance the effectiveness of their internationalization process and strategy. The researchers also indicated that there tends to be a consensus in the literature about the influence of focal customers and larger organizations in strategic networks. This study highlighted how small and medium-sized silk suppliers adopt the roles attributed to focal firms and gain positioning advantages for themselves and other suppliers in their network. Karmenidou (2007) carried out an exploratory study on the reasons for purchasing imported high fashion apparels: The case of Greece. The purpose of the study was to examine the reasons that Greek consumers purchase imported high fashion apparel over Greek designers high fashion apparel. The specific objective of the research was to detect the underlying factors that affect their purchasing behaviour. Qualitative research was conducted through discussions with consumer focus groups, all purchasers of imported high fashion apparel. Quantitative research was undertaken by means of a questionnaire with 28 items referring to the reasons for purchasing imported high fashion apparel. The sample consisted of 200 high fashion consumers from the city of Larissa, Greece. Data analysis includes descriptive statistics, reliability, as well as factor analysis by principal component analysis with Varimax rotation. This research was exploratory in nature and employed a non-probability sampling method. Results indicated that the consumers perceive that the imported high fashion apparel have better aesthetics, a better line and are produced from quality textiles, compared to the domestic high fashion apparel. Four factors derived underpinned the purchasing reasons of imported high fashion apparel: â€Å"status and image†, â€Å"quality of the product†, â€Å"marketing reasons† and â€Å"in fashion†. This study provided a useful source of information, which can be used by Greek high fashion apparel designers regarding the reasons why Greek customers of high fashion apparel purchase imported over domestic ones. The study suggests which elements Greek designers of high fashion apparel should focus upon in order to gain a larger market share. This study was important in terms that it was the first one to explore the reasons for purchasing imported high fashion apparel over domestic ones in Greece. It highlighted 28 reasons (items) derived from qualitative research. In addition it suggested appropriate quality and marketing actions to be undertaken by Greek high fashion apparel designers. Baker (2006) looked at the topic â€Å"Fashion industry facing challenges†. According to him, the Australia’s fashion industry faces many challenges including the rise of low-cost goods from Asia, a slowdown in consumer spending and the need to respond quickly to changes in trends. crippling household debt and low-cost Chinese imports increasingly will dominate the local fashion scene. â€Å"With house prices stagnant and the ongoing threat of an interest rate rise, people are readjusting their spending habits. Having spent beyond their means for many years, the debt to income gaps need to diminish, which means shrinking the value of goods bought on credit. According to him, the clothing industry is set to bear the brunt of a consumer slowdown in spending which would spell disaster for some local manufacturers. The ability of local production to respond quickly to changes in fashion trends is also crucial for survival. In his view, manufacturers will need to build closer relationships with retailers to help them respond more appropriately to consumer demand. Another challenge came from rapidly rising imports, particularly from China which accounts for 59 per cent of industry imports. Smaller, independent operators should always be on the lookout to increase efficiencies, develop effective branding and market strategies and attack key niche segments to make financial gains. One growth area for smaller players was on line selling, or e-tail, with its low set-up costs. Online sales currently account for just two to five per cent of retail sales in Australia but predicted that figure will increase with rising levels of broadband penetration. Revenue is leaking from our fashion industry as retailers who have been slow to catch on to building an online presence are losing out to overseas labels that are selling direct to the Australian public online. A survey undertaken by logistics group DHL found that the trend for local designers to go offshore could have a negative effect on the Australian fashion industry. The Business of Fashion survey showed that 90 per cent of respondents, which included designers and manufacturers, believe more garment manufacturing is headed offshore. The survey found that the industry needs better business training and more help to export if it is to remain competitive. Kalman (1999) wrote an article on how globalization has affected the fashion industry in the West Coast. While the West Coast sewn products industry is not exempt from downward domestic production trends faced by the rest of the United States, the region continues to stay one step ahead of the game thanks to its strengths in quick-turn fashion and flexible production. Suppliers to the market are focusing on these strengths as well as the challenges facing West Coast producers – namely the lure of low-cost sourcing south of the border – as they prepare to participate in the 1999 Sewn Products Expo – Los Angeles, which takes place April 22-24 at the Los Angeles Convention Center. Looking at the factors that have driven the West Coast industry's growth, Lectra Systems Inc. vice president of marketing Rick Ludolph observes, â€Å"As West Coast firms have always been more fashion-driven, they have adapted better than more traditional manufacturing regions of the country to the need for fast, flexible production. †¦ Southern California, in particular, maintains a favorable value proposition with good labor availability at relatively low labor costs when compared to other U. S. regions. † Likewise, Mike Grogan, vice president of Apparel Machinery & Supply Co. notes that despite the migration of production offshore, the We st Coast apparel industry â€Å"still [has] a good core of smaller manufacturers, particularly in the Asian community, which can offer quick response to sudden fashion trends and short production runs. † The source of most West Coast production is California, which continues to lead U. S. apparel industry employment with a 1998 work force of approximately 168,700. The state is home to some 7,400 fashion-related companies that account for $47. 7 billion in annual wholesale sales, the California Fashion Association reports. Yet the growth of manufacturing activity in Mexico has had deleterious effects on apparel jobs, even in California. â€Å"This is particularly true in the most basic product line. People on the lower-priced budget end are almost completely forced out of the U. S. It's very difficult for them to make the high-volume, low-cost products here anymore. Moreover, From anywhere in Mexico you can be anywhere in the United States on the ground in four days, so transportation issues aren't really a problem anymore either. † Tight retail margins also are driving more production to Mexico. As Byte Systems director of sales and marketing Brad Mikes asserts: Retail price points are still the defining issue. Sewn products will continue to move to Mexico because of its proximity to the U. S. , the industry growth in Mexico, and because of the labor cost reduction [associated with] manufacturing there. Still, California has assets, such as its highly skilled work force and quick-turn manufacturing capacity that Mexico has yet to match. With regard to the state's growing apparel work force, Ludolph emphasizes: â€Å"This is a result of the strong demand for skilled labor, which is required to produce much of the women's wear and sportswear that is dominant in the region. †¦ [Subsequently] the availability of skilled, efficient labor is key to maintaining the apparel industry on the West Coast. † As the region's labor pool is fueled by an influx of Latin American immigrants, it promises to have a positive impact on maintaining jobs that might have otherwise moved to Mexico. With regard to flexible manufacturing, Robison-Anton Textile Co. president Bruce Anton notes that streamlined logistics and just-in-time production are playing an increasingly important role in the success of California's apparel industry, whereas â€Å"Mexican manufacturers have not adjusted to this yet. † Isenberg adds that with fashion-oriented orders, California contractors can maintain an edge over those of Mexico, which has very few â€Å"fashion factories,† as well as Asia, which requires long lead times. While â€Å"the days of having big runs come into domestic factories are all but over,† he says, California firms can still win if they are willing to run many different styles and small cuts. Indeed, without the security of big runs, many West Coast companies have had to become more acutely attuned to the caprices of the marketplace. As Joe Hollander, president of AC/Automated Components observes: â€Å"We have noticed that some factories are downsizing their operations and gearing themselves toward smaller production runs with an emphasis on quality and quick turnaround. We also see an emphasis on the ability to make subtle changes in the product to customize it for specific stores, chains, etc. † From a financial perspective, JBA International's Joe Facenda, senior consultant for apparel and footwear, concludes: â€Å"Our region is more influenced [than others] by the constant flow of new companies. Our designers and supplier network make us the Silicon Valley of the apparel industry,† he emphasizes, and this status breeds â€Å"a great need for more capitalization† so that start-ups and established companies alike don't â€Å"stay behind the capit al curve. † AHRC (2007) IN THE STUD OF Key Challenges in Adapting to New Models in the fashion industry ASSERTED THAT While companies are managing to adapt to offshore sourcing, they are slow to become world class in other parts of the value chain. Challenges are both company specific and general to the industry. The Study indicated that most participants had â€Å"operating basics† right, including being able to produce a value for money product that meets the end consumer needs at the right quality level, delivered on-time, with the proper service that retailers demand. However, the same study noted several weaknesses. A startling 58 percent of companies did not have the financial acumen, information or general expertise to identify the true profit drivers in their company. Without this information, these companies have been unable to distinguish profitable versus unprofitable segments of their business, and thus often unable to identify the most profitable niches to grow;58 percent of companies did not have a strong management team, implying that their own internal management competencies may be preventing them from reinventing themselves;While 67 percent of apparel companies operate within a niche, 62 percent do not offer the customer anything that differentiates them from the competition. Contractors were specifically noted to have even greater internal challenges, including:Extremely weak sales and marketing capabilities: Many companies tend to be dependent on relatively few longterm customers; These companies do not have an owner or key employees with significant sales capabilities;Weak financial and costing which impede their abilities to determine profitable contracts from unprofitable ones;Poor workforce cross-training capabilities / flexibility. A World-Class Focus of Excellence Key challenges per company will also vary based on the model being pursued. In general, the following table illustrates the key challenges depending on whether a company intends to maintain an element of the value chain in-house and make it a core focus or whether it intends to outsource it: Beyond specific business model challenges as noted above, certain general challenges will impact industry players as well:Decreasing Domestic Supply Chain As manufacturing continues to move offshore, domestic apparel manufacturer suppliers (textile companies, label producers, thread companies, etc. ) will face greater challenges; In all likelihood, these suppliers will continue to face consolidation and closures; As the supply chain erodes, it will become increasingly difficult for those apparel companies wishing to manufacture domestically to do so. The 2003 AHRC LMU noted that while most industry executives were aware of the coming industry restructuring, 87 percent did not have a strategic plan to deal with the issues. The 2007 AHRC Study confirmed this still to be the cases at the onset of the program, some three years later. While the 2007 AHRC Study provided assistance to 130 apparel companies, presumably there continues to be many apparel companies without well-rounded management teams. Beyond specific value chain shortcomings, key weaknesses tend to be in the areas of strategic and financial management. Of all participants in the 2007 AHRC Study, 27 percent will face a succession issue within the next 5 years; 42 percent within the next 10 years:Most of these companies do not have succession plans;There is a strong correlation between companies that have succession plans and strategic plans; i. e. , if a company does not have a winning strategy in place, it likely does not have a succession plan;Without succession plans, many of these companies will face business continuity issues in the short to mid-term. The issue of access to capital for the apparel industry is not new. For years, apparel companies have indicated that they feel there is a lack of support for their industry from the banking community. While there may be some truth to this, it may be for good reason. As previously noted, consider that of the 2007 AHRC Study participants: 56 percent did not have a strong management team in place; 58 percent were not able to determine the true profit drivers of their business; 87 percent did not have a strategic plan that could be acted upon; 61 percent were not willing to reinvest in their businesses. Under these circumstances, it is not a surprise that many companies could not / cannot secure financing. Nevertheless as a result of banking formula-based lending practices, we believe that financing remains a challenge to many well-run apparel companies and small businesses in general. SMEs at times, also have difficulty securing financing from other lenders. For example, asset based lenders often require substantial premium interest rates. Other larger non-traditional lending institutions and professionals that can assist prefer working with larger companies where greater fees and returns can be earned. The traditional financing problems will likely become further exacerbated as companies implement new models that do not generate assets that can be collateralized. Consider: Soft cost expenditures are often required to implement new models (i. e. esigners, marketers, sales and service personnel, increased travel, training and marketing costs, These expenditures offer no collateral security to lending institutions and as a result, are difficult to finance; Inventory financing costs are increasing, often as a result of shifts to imports; Requirements to fund export receivables are increasing. To further exacerbate the issues, many executives appear to often strip equity from their companies as opposed to maintaining this capital for future reinvestment. Employment will shift from predominantly production jobs to balanced or predominantly white collar positions. New models will require companies to hire world-class talents in areas such as design, marketing and logistics. According to the 2007 AHRC Study, positions to be most in demand include: Sales professionals (sales managers, brand managers, sales representatives); Marketing professionals (marketing managers, marketing analysts, merchandising technicians); Designers (product developers and design technicians); Import / export specialists; This talent appears to be in short supply and in demand by other industries as well. Apparel companies will be challenged to recruit, train and retain these key personnel. Financing such salaries will also be a challenge to companies. According to the 2003 AHRC LMU, 87 percent of Canadian apparel companies had less than 50 employees. Less than 7 percent of companies employed more than 100 personnel. This SME industry structure partly explains the lack of management sophistication in the industry. In order to reinvent themselves, many companies will need to increase their size in order to support greater white collar needs. We believe that this will lead to: Further industry consolidation; Continued merger and acquisition activity (for companies that have established a niche but need greater volume to expand and operate on a larger scale); Partnering / allying / creating joint ventures with world class specialists in order to remain competitive. Such partnerships are likely across the entire value chain in the areas of design, marketing, manufacturing, sales, logistics and distribution. As in the banking sector, much of the professional expertise in this area (business brokers for example) may be out of reach to many SMEs. Professionals in these areas prefer to work with large organizations whereby they can generate substantial fees as opposed to the SME marketplace. There are relatively few barriers to entry in launching an apparel company. As a result, the industry is constantly regenerating. Consider that nearly one third of all participating companies in the 2007 AHRC Study were established within the last ten years. Many of these companies are being founded by new designers graduating from colleges or individuals who have identified an underserved niche. Unhindered with the baggage of yesteryear, many of these companies have viable new business models. In these cases, the challenge is often to secure adequate industry specific managerial talent and financial resources to grow the company. CHAPTER THREE METHODOLOGY 3. 1 RESEARCH DESIGN The research used the survey design. Independent variables which were assessed cultural, globalization, pricing, product design and promotion challenges in the clothing sub sector of the fashion industry. Assessment was made to see their effect on the industry. Both qualitative and quantitative tools were used for the research. The design factored in large scale fashion designers, medium scale designers and tailors/seamstresses. The stratified and simple random sampling methods were used. 3. 2 POPULATION AND SAMPLING 3. 21 Population and Sample The research targeted large scale cloth designers, medium scale designers and tailors/seamstresses in Accra. The large scale designers are those who produce on large scale for the Ghanaian market and still export some. The medium scale are those who produce for the Accra market and a few for other regions. The tailors selected were those imitate and create designs based on the specifications of others. A sample of 120 was chosen. It was made of 10 large scale, 50 medium scale and 60 tailors/seamstresses. 3. 22 Sampling Strategy The research stratified the population into 3: large scale designers, medium scale designers and tailors/seamstresses. Simple random sampling was then used to select the sample in each stratum. A List was obtained from the Association of Fashion Designer and the Association of Tailors and Seamstresses. They then given codes and put in a basket. The sample was then selected randomly through the lottery approach. 3. 3 RESEARCH PROCEDURE A letter of introduction was taken from the Methodist University College. Copies were made and addressed to the leaders of Associations to seek approval for preliminary interview to have insight into the challenges of the industry. The leaders of the associations gave out the list of members, location and telephone numbers. With the help of the leaders, 120 respondents were selected. The researcher upon meeting the respondents explained the topic under study, stated the purposes, relevance and benefits of the research. Upon the approval of the Heads, the respondents were given the questionnaires. The researcher and his research assistants used a period of four (4) weeks to collect the questionnaires from the respondents. Out of the 120 individuals identified and given the questionnaires, 108 responded to the questionnaires, representing a response rate of 90%. 3. 4 RESEARCH INSRUMENT The primary data was collected through the administration of questionnaires based on our aims and research questions The questions were in †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. The questions used in this research were two types: open-ended and closed-ended questions. The reason for the open-ended questions was to allow respondents to express their views in the way they desired. The closed-ended ones were used to ascertain specific answers. 3. 5 STATISTICAL ANALYSIS Qualitative and quantitative methods were used in this research. These two methods complement each other. Qualitative research can be used in all disciplines and subject matters and its main aim is to gather an in-depth understanding of reasons and human behaviour. It investigates the why, what, how, where and when of decisions making and human behaviour. The research used bar graphs and frequency tables to analyse the data. The researchers also used the Statistical Package for the Social Sciences (SPSS) for the analysis.

Class mobility

Classes have been studied under five classifications and similarly castes have classified under eight categories and both are socially viable. Absolute mobility has been used to study intergenerational social mobility and after allowing for structural changes, relative mobility has been analyzed by using odds ratio. Finally to study the effect of castes/community on social mobility logistic regression have been used with access to salariat class destination as dependent variable and class origins and castes as independent variables.To look t the trends over time, five year birth cohort data have been used with focus on father's occupation to avoid any impact of life-cycle process. Since India has gone through various social economic changes over years, like a capitalist country it is expected to become more open with greater equality of opportunities after liberalization of post 1980s. Therefore, equality of opportunity should rise along with a rise in absolute mobility. Discussion t o patterns of intergenerational mobility of men and women is limited only to paid employment.Paper pointed out that proportion of Indian labour in trade, manufacture and services has risen but the largest workforce participation still remains in agriculture. There has been an increasing room at the top and agricultural workers and farmer's participation has declined over time. More women as compared to men remain in agricultural occupations. Also, the occupational change has been there prior to liberalization. Therefore, we do not see any impact of modernization in the changing occupational patterns.Crosstabs of NES data between classes of father and respondent clearly shows a stable intergenerational society for both men and women. A trend analysis of absolute mobility shows decreasing upward mobility and increasing downward mobility as opposed to our hypothesis. Trends in inequality of opportunity calculated by using odds ratio and then by log linear model (appropriate way to test for increasing fluidity) shows a clear pattern of increasing inequality of opportunity both in agriculture and informal sector but grater in farming sector.A higher odds ratio of armer: salariat than manual: salariat ratio points out some sectoral barriers in addition to class barriers. Also, the movement between farming and salariat Jobs is harder for women. Overall there has been little demonstrable increase in equality of opportunity in Indian society. When the impact of castes was analysed is was seen that by using the logit regression and recoding castes in eight distinctive categories no clear trend could be observed for both men and women. Rather the father's class nas been a strong determining tactor tor access to salaried class destinations.Surprisingly India which is a caste based society and policies of reservation are also based on castes, it is the class which determines the upward social mobility. Caste reservation does not seen to have benefitted the SCS and STs as m ight have been hoped. CRITIC The paper in the beginning explained various modernization theses and asking research questions based on demand and supply side issues. It was said that we explore these various possibilities in remainder of the chapter. But the whole focus was concentrated only on class and lastly caste analyses.Competitive market, formalized recruitment procedure and equality of condition were not incorporated as results of modernization as per my understanding. I am not aware though if such a method is possible. Secondly, not undertaking the marital social mobility of women has been considered a limitation in the study but since the paper looks at the social mobility in terms of access to salarit Jobs, marriage of a women to a higher class individual than her father does indicate a net upward social mobility of her living tandard but not her chances of getting a better Job.Even if this argument doen't sounds good then a social mobility through marriage is not in any c ase an indicator of modernization of society. Lastly, in the birth cohort method, one has to self calculated roughly where exactly the period of liberalization has been shown on the table or graph. Since our focus is on modernization, had there been a mention of period of liberalization along the birth years it would have been easy to anlyze the changes before and after the liberalization.
