A Critical Response to the Editorial “Productive Labour” Essay Example for Free

A Critical Response to the Editorial â€Å"Productive Labour† Essay â€Å"A Productive Labour† is an editorial written by Roger Martin and James Milway. This tackles on the topic of productivity – what it is, what it does, and just how important it is for a country’s economy and living. The essay’s main point can be seen in its secondary title, which states that â€Å"the only limit to productivity growth is human ingenuity.† The article’s strength lies in this statement, and supported by the many reasons the authors discussed afterwards. Although the essay is strongly put together, with the main points being clearly stated, there is still the existence of some weaknesses, evident in many parts of the article. These loopholes are either poorly explained or there is no sufficient evidence presented to actually support it.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The authors, in this essay played the role as lecturers and persuaders at the same time. They started off by discussing productivity by stating it as a practical way to raise our living standards. They gave an assertion that the only limit to productivity is the human ingenuity, unlike other methods which would use up all of the natural resources, or the number of hours to work. From here they gave specifics on how to actually increase the productivity. One of their main arguments here is the use of what they called â€Å"new value creation† (par. 10). This, together with strategies leading to innovation will drive a country’s productivity higher. The editorial also contained written benefits of productivity, and how it can help a country’s growth.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   One interesting fact that the authors pointed out is that the limiting factor of increasing a country’s productivity lies in ingenuity. This seems to be partially true, because the article defined ingenuity as the only limiting factor, when in fact in a practical world it is not. The article in the succeeding paragraph stated that a â€Å"countrys ability to improve its standard of living over time depends almost entirely on its ability to raise its output per worker (par. 6). If productivity is the key to raising the standard of living, it is then limited by the output of each worker. And any worker, no matter how ingenious he or she may be, will only reach a certain level and never go beyond it. This is a practical theory of everything; no matter how long and how much energy you put into something, it will reach a point where there is no useful output produced. Then, the next step would be to find a new worker with new and fresh ideas. Over time, productivity will not only be limited by the workers’ ingenuity, but also by the number of workers available and efficient enough for the tasks.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Although compared with the limitations caused by natural resources, productivity still has an edge. Taking into account the length of a worker’s useful ingenuity and the possible number of workers available, the depletion of natural resources would come to dawn at time earlier than this.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another eye opening fact is the information on new value creation (par 10). This is truly one important way of increasing productivity and it is covalently linked to ingenuity and innovation. These unique creations are a wonderful way to not only enhance a worker’s thinking skills, but also create an edge in the economical tug-of-war. Instead of trying to compete against a nation who perfected a certain technology, others can develop a technology different from it. And if that technology or product becomes a hit, the nation pioneering that new design would benefit greatly from it. This is just a way of showing how productivity can be translated to economics and businesses, just like the article suggests. But it should not forget the prerequisites for an actual new creation to be born. First would be the development of science and technology in the country. The chances of creating a new product would greatly rely on the technology readily available. A man may have designs on creating the world’s greatest car but if the society lacks the tools and techniques required in making one, these innovation would not be manifested as a usable object. Again, it is not always practical for a new creation to make its way into the conceiving stage.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Finally, the article speaks to a very broad audience. Its first paragraph ended with a challenge to governments, businesses, and citizens (par. 1). The whole article in a sense is then dedicated to every single one person of a country or nation. The productivity challenge is something that everyone must be a part of. It is true that although many think of productivity as a term only used in labour, or businesses, it should actually encompass every being that contributes to the society. Citizens, by the simple due of paying their taxes, enters the world of productivity and contributes a part of that to the government, which in turn must make use of these taxes in a very much productive way. For the work force, productivity would be of benefit for them since it means higher wages.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In a nutshell, the editorial speaks clearly of the purpose and strength of productivity in our daily lives. Its arguments are supported by concrete examples and the essay is in fact very persuasive. There are just some little details which may not be noticeable at first. These usually jump in the practicality of the suggestion. We must always take into consideration the practical events that would happen and define them differently from the hypothetical or theoretical events. This way, factors can be explained much better without bias. References Martin, R., Milway, J. A productive labour; the only limit to productivity growth is human ingenuity.

Significance Of The Representation Of The City English Literature Essay

Significance Of The Representation Of The City English Literature Essay In this essay I will be discussing three very diverse texts which will allow me to bring into light a various number of views and interpretations of the city. I will be focusing on D. H. Lawrences Women in Love, T. S Eliots The Waste Land, and finally Virginnia Woolfs Mrs Dalloway. All texts will help me come across the different insights, views and personal feelings towards the city the authors felt. Many of these authors develop their ideas and emphasise on the affects of the city through their characterization, this essay will further help me develop the representation of the city and look into it in more detail. I will focus on a number of areas such as characters, settings, thoughts and views in the texts in order to gain an answer as to what the significance of the representation of the city may in fact be in connection to its authors. As we read on through the poem, Eliot continues to present the Waste Land as a very complex poem; it tackles and confronts a variety of contradictory ideas and understandings. The intended meaning of the poem may come across as something different to both critics and readers; it can in effect be seen as a text that can have a variety of meanings and can be interpreted by anyone in their own ways. The text can be seen as being interpreted through the person and society, or can also be interpreted on a personal note where Eliot may seek to reveal his own feelings and intentions as to why he wrote the poem. The main theme of the poem can be distinguished through the way in which Eliot portrays modern life as a Waste Land. He supports this theme by showing what was wrong with society in the early twentieth century. He demonstrates the lack of faith in the poem through a number of ways; he puts into words the weakness of society by presenting a certain lack of faith, lack of communication , and corruption of life, alcohol and sex. At one point he shows one of the characters saying I can connect nothing with nothing.  [4]  This indicates the character having no faith or confidence in them self; there seems to be no connections and no meanings to her life, it seems to come across as though her life is just a waste. In the text Eliot speaks about the crowdedness of the city many of times. The Unreal city, Under the brown fog of a winter dawn, A crowd flowed over London Bridge, so many, I had not thought death had undone so manyà ¢Ã¢â€š ¬Ã‚ ¦ The fast paced text conveys allusions which create a sense of crowding in the city. London is depicted as a very busy city, a place where something is always happening; it is illustrated as being different in contrast to what you would experience in the countryside. The Waste Land creates an unattractive image of London, we feel appalled by the amount of industrialization taking place as the surroundings are described as being encircled by the brown fog. The depiction of the industrialized city can become so shocking and brutal that it can in some ways be seen as a character. Furthermore The Waste Land conveys several distinct images that help to present a deeper meaning to the text. As we read through the poem, we come across the lines Sweet Thames, run softly, till I end my song.  [5]  This sentence conveys a feeling of sadness and obscurity. This frame of mind is related to the lines that follow which talk about death and sorrow, the mood of the text comes across as very dark and threatening. One of the main points seems to come into light through the portrayal of the River Thames. This river can be seen as symbolising death, it is like a bridge which the dead spirits need to cross over in order to face death. By saying that this person wants the river to run softly before the song ends indicates that this character is near death, and after his story has been said, he will be ready to accept it. Death in itself is a very dark topic in relation to the title of the poem; this passage can be seen as linking the time and the place together before death . The place is shown not to exist in the living world or the dead; it is conveyed as being something which is in between. This area can be seen in many ways as a Waste Land just as the poems title suggests. The Waste Land can be linked to many things in this poem, in this case it can be where the river Thames lays, a place where the living and the dead do not inhabit. The imagery bought across in these lines is very effective in relation to the mood and themes they set in the poem. They give the mood of sadness and mourning which gives deeper meaning to the rest of the text. All the way through the preceding lines after the Sweet Thames, there is a sad mood which flows in the course of the text. As the readers read on in The Waste Land, they get a feeling which indicates that even if they were to read something happy and cheerful in the poem it would still have a dark effect. The imagery of death, sorrow, sadness and gloom is very effective in this case as it allows the poem to set a feeling for the rest of the text. In the Waste Land à ¢Ã¢â€š ¬Ã‚ ¦the images and symbols fall broadly into two categories-firstly, images drawn from myth and religion, and secondly, images taken from the common aspects of urban life.  [6]   The modern city in contemporary literature is shown to be very complex in the 20th century. Within literature there are a number of writers who move towards the physical reality of the modern urban life and surroundings; Virginnia Woolf in many ways is a good example of this. In her novel Mrs. Dalloway, we are presented with the citys obscure feelings that link the perception of the two main protagonists together. The characters Woolf looks at are the the centre of life itself  [7]  . On the contrary, D.H. Lawrence has been the most provocative of modernist authors  [8]  , he shows his own understanding of the city as a place of desolation and division. His text Women in Love illustrates London as a corrupted city which is populated by outward characters who can only find their pleasure and happiness in sex, drinking and taking part in criminal activities. Both of these modernistic texts allow us as the readers to identify the different representations of urban life in a chan ging city; we are presented with images of the actual London and the illusory London. Both of these texts can in many ways portray similar themes, feelings and ideas towards the city which The Waste Land has previously been seen to do in this essay. In addition Mrs Dalloway and Septimus are characters in Woolfs novel who capture the passing moments of their lives in a city. Both of these characters are shown to be walking through the city and feeling the liveliness of London. Their responses to the same city symbols vary from one another. Septimus Smith says everything had come to a standstill  [9]  whereas Mrs Dalloway shows us she is amused by the noise and high energy of the city life. The opposing reflections both of these characters present show how their everyday city-occurrences result in a contradictory presentation of the city life; it offers an accurate sense of reality within this way of life. We can see this being present in the novel as Woolf uses free indirect speech. Her form of expression is a good linguistic technique in the novel; it acts as a verbal counterpart to the mental moments of uncertainty within the reality of urban life. In this sense, the contrasting reflections on the same incidents and Woolfs new form of expression result in an overlapping of the characters consciousnesses which at the same time link to images presented in the novel. In D.H Lawrences work on the other hand, traditional language is not enough to show his understanding and feelings towards modernity. The city is illustrated as a complex, and socially diverse place, the new forms of expression are essential in order to work in opposition to the growing sense of isolation. Lawrence is shown to be using repetition in his work in order to bring across the crowdedness and light-headedness of the atmosphere in the city. Birkin says I always feel so doomed when the train is running into London. I feel such despair, so hopeless, as if it were the end of the world.  [10]  The diction Lawrence chooses to use is very interesting to look at, he uses hopeless in different contexts and repeats himself in order to bring across Birkins emotions towards the city. We can say that the actual meaning of the diction he dec ides to use may in fact change and be a connection to the modern city and environment where it bears a resemblance to the new time of order and effectiveness. The characters in Women in Love are shown to undergo different experiences and feelings in relation to the modern city, for example they are shown to feel misery and corruption in the text. Lawrence brings across the unattractiveness of the urban and industrial city and establishes the citys mentality into the minds of the miners. As a result, he creates a perfect, inhuman system of machines, where the miners begin to deny their humanity in feeling satisfied to belong to the great and wonderful machine, even whilst it destroyed them  [11]  . There is a lot of depiction of the state of mind in Women in Love; Woolf also brings across this mental absorption of the citys characteristics through the characters she presents in Mrs Dalloway. Doing everything on time and being exact is something which is part of most modern minded people, this is symbolised by the way in which time is shown on Big Ben in the novel. Virginia Woolf presents the city as a physical place presenting the menta l state of mind of the characters. For Mrs Dalloway à ¢Ã¢â€š ¬Ã‚ ¦silence falls on London; and falls on the mind  [12]  , this in many ways indicates a deep connection between the inner thoughts and emotions and the outer world. Septimus consciousness reflects the understandings of the outer world. He did not want to die. Life was good.  [13]   There are many ways in which we can see that the link between the city and the mental life is illustrated through the character of Peter Walsh. On one hand Peter suffers from the loneliness in London as he feels a strangeness of standing alone, alive, unknown, at half-past eleven in Trafalgar Square.  [14]  However he also uses this feeling to keep track of the young woman before she is lost in the city crowd. Peter chasing the young woman may in fact symbolize the change of social behaviour and interactions between the two sexes within the restrictions of the city. In Women in Love a new directness regarding sexuality is presented as a consequence of the changing cultural environment in the city. Alcohol and sexual excitement are presented as the main occupations of the Pussum and the other residents of the flat. Although Gudrun regards London as a foul town, it is within the urban city where her new understanding of art is recognized. In the flat, a weird number of modernist wo rks of art and influences are shown to symbolise the directness to non-traditional art. Within this environment of the modern city, we are presented with the Brangwen sisters as having much better chances to live their eminent individual personalities than within the well-known closeness of urban Beldover. Although Birkin and Gudrun detest the masses, Mrs Dalloway looks at the small crowdà ¢Ã¢â€š ¬Ã‚ ¦gathered at the gates of Buckingham Palace  [15]  from the distance it becomes striking and beautiful. It is the sense of an endless society and quality which attracts Woolf, Lawrence nonetheless is shocked by the crowds single mindedness. It is interesting to note that the characteristics of the crowd are not obvious for all citizens of the city. In conclusion we are able to identify the significance of the representation of the city in all three works by Lawrence, Eliot and Woolf. There are many different modernist representations of the city which come across in all three texts. What T.S. Eliot pictures as an isolated, distressed area, is in fact for Virginia Woolf a symbolic landscape of life and vibrancy, and for D.H. Lawrence an urban area of despair. All three diverse understandings and ideas of the city are reflected in the characters presented in the texts by the modernist authors. For this reason we are shown how Mrs Dalloways consciousness presents an optimistic image of the city, which is contrasted by both Birkin and Gudruns negativity. On the other hand, we do not only get the general approach of the presentation and its significance, the authors are shown to be expressing their personal and individual understandings and views of the city. The citys attitude of precision is symbolised within Geralds modernization of the coalmines which introduce the perfect inhuman machines to Beldover. Exactness can also be found in the strikes of Big Ben in Mrs Dalloway. Furthermore, in Mrs Dalloway the cities characteristics are mirroring the state of mind of the characters and give therefore another perspective of the urban landscape. In addition, Lawrences and Woolfs new modernist techniques of expression have the ability to cope with the progressively altering conditions of modernity within the city life. Woolfs free indirect speech gives a full meaning and insight into the awareness of the characters, therefore giving them a much better and accurate understanding of their own individual views of the city. Lawrence uses repetition in his language in order to improve his conventional understanding of particular terms and provides the city with new characteristics. As a result, the individual and subjective experiences of the authors offer a complex and deeper picture of the reality and unreality of a w eak city. WORD COUNT: 2732

An Overview Of The Date Palm Environmental Sciences Essay

An Overview Of The Date Palm Environmental Sciences Essay Date palm (Phoenix dactylifera L.) is known as tree of life plays an imperative role in the life of the people living in scorched regions of the world. It is an ancient and valuable fruit, as the dates name has been and is mentioned in holy books like the Quran, Torah and Buddha (Belarbi et al., 2000; Falade and Abbo, 2007). Prophet Muhammad (PBUH) is reported to have said that the best assets is the date palm, that it is used for curing many disorders, and He (PBUH) urged Muslims to consume dates (Zaid and de Wet, 1999). Muslims deem it as a virtue to eat dates at Iftar in the month of Ramadan. It has been cultivated in the Middle East since at least 6000 BC (Al-Qarawi et al., 2003). At least 2000 or more different cultivars of date palm exist all over the world (Ali-Mohamed and Khamis, 2004). The Date fruit provides a good source of carbohydrates, fibre, minerals, and vitamins, but it contains a minute amount of fat and protein (Baloch et al., 2006; Al-Farsi et al., 2005; Mohamed, 2000). Date fruit is also suitable for hypertensive persons because of its high amount of potassium and low content of sodium (Al-Hooti et al., 2002). New studies have reported that date fruit has antimutagenic and anticancer action (Ishurd and Kennedy, 2005; Vayalill, 2002). The ripening of the date fruit is considered by four different stages/phases based on color, softness, moisture, and sugar content. (1) Kimri stage: at this phase the fruit is quite hard, the color is green and it is not fit for edible purpose. At this phase the fruit attains a rapid increase in weight, volume and build up of reducing sugars that will weaken at the end of this stage. (2) Khalal stage: at this stage, date fruit gains its maximum weight and size. The dates total sugar and acidity will boost as its water content decreases. At the end of Khalal stage, the fruit is physiologically mature and hard. (3) Rutab stage: ripening of date fruit starts at this stage. Its colour changes and its texture become soft. It begins to lose astringency and starts acquiring a darker and less attractive colour than the previous stage. (4) Tamar stage: the date fruits are fully ripe at Tamar stage and texture of the flesh is soft. At this stage, date fruit contains its maximum total solids an d it is in the best condition for storage. Some references have mentioned another a very early stage named called Hababauk. This term is used for the female flower and also used for the period after pollination, in which the young fruit is still creamy before gradually turning green at the Kimri stage. Generally, date fruit is harvestable and marketable at three stages including Khalal, Rutab and Tamar that depend on cultivar characteristics, especially soluble tannins levels (Ismail et al., 2001; Hong et al., 2006; Awad, 2007). Although there are many cultivars of dates, some have become pre eminent in the world market (Krueger, 2001; Nixon, 1950). Deglet Noor, meaning date of the light in Arabic, comes from the Algerian Sahara and is one of the leading cultivars grown in North Africa and California. Halawy, meaning sweet in Arabic, is a soft, high-quality date with rich flavour from Iraq. Khadrawy, meaning green in Arabic, is a short and moderately productive tree with soft fruit from Southern Iraq. Climate is one of the major factors that affect all aspects of life and realistic crops cultivation depends on proper understanding of climatic condition. Proper understanding of climatic condition can help farmers in doing cultivation at an opportune time and supplying plants needs during growth period. The ripening season of date palm starts with the rise in summer temperature with July and August, which is the peak production period. Unfortunately, the monsoon rains also falls within these months of the year, which is a real bottleneck for this crop. Hillawi and Khadrawi are the major varieties cultivated in Punjab. These varieties are semi dry and ripened early in July and face a huge problem of monsoon rains. The coincidence of date ripening period with the monsoon season means the crop receives heavy damage by rain and a few minutes of rain can destroy upto 80% of the date crop (ASF, 2010) The fruit during this period is at eatable (Khalal/Rutab) stage and prone to infestation by insects/birds and diseases that invade at a rapid rate under the favourable climate of relatively reduced temperature with high humidity. This adverse situation persists for several weeks. The extent of the losses contributes to accumulate so long as the fruits stay on the trees for want of Dong formation until the end of July (Saleem et al., 2005). Rain and high humidity may cause physical damage to the fruit in period preceding the ripening. When this happens, cracks appear on the fruit surface through fungi and bacteria may enter causing fermentation and souring of the fruit rapidly (Olin, 2002). It is worth mentioning that the amount of any particular rain is of less importance than the conditions under which it occurs (Nixon and Carpenter, 1978). Traditional methods of date fruit ripening/curing are popular in many areas of the country, in which fruit at the Dong stage are spread on the mats or plastic sheets and exposed to sun in an open air. The quality of sun dried product under dusty condition becomes very poor and non-uniform with a low yield. Due to persistent rain and stormy conditions a large amount of the harvested dates become mouldy, fermented, and dusty, damaged by the birds and insects. The present study will be therefore conducted on the ripening aspects and fruit quality of date palm with respect to monsoon rains, by evaluating the potential of preharvest ethephon application on ripening enhancement and fruit quality of date palm at Kimri and Khalal stages, studying the role of different chemicals on the ripening behaviour and fruit quality and ripening and quality assessment of date fruit will also investigated by the influence of hot water treatment by harvesting the fruit at the physiological maturity (Doka/Khalal) stage. V) REVIEW OF LITERATURE: Fruits should be harvested at the correct physiological maturity and state of ripeness (Harman and Patterson, 1984). They are self sufficient with their own catalytic machinery to maintain an independent life, even when detached from the parent plant. Based on their respiratory pattern and ethylene biosynthesis during ripening, harvested fruits have been classified as climacteric and non-climacteric based on the respiration pattern and ethylene production during ripening. Climacteric fruits, harvested at physiological maturity, can be ripened off the parent plant. The respiration rate and ethylene formation though minimal at maturity, raise dramatically to a climacteric peak, at the onset of ripening, after which it declines (Gamage and Rehman, 1999). In climacteric fruit, onset of ripening is accompanied by a sharp increase in respiration and ethylene production. The climacteric ethylene is thought to regulate fruit ripening by inducing the expression of many ripening-related genes responsible for autocatalytic ethylene production, cellwall metabolism, chlorophyll degradation, synthesis of carotenoids and volatiles, and conversion of starch to sugar (Gray et al., 1992; Theologis, 1993; Alexander and Grierson, 2002). Non-climacteric fruits are not capable of continuing their ripening process, once they are detached from the parent plant. Also, these fruits produce a very small quantity of endogenous ethylene, and do not respond to external ethylene treatment. Such fruits show comparatively low profile and a gradual decline in their respiration pattern and ethylene production, throughout the ripening process (Gamage and Rehman, 1999). In non-climacteric fruit, there is no dramatic change in the rate of respiration, and ethylene production remains at a very low level. However, in some plant species, some aspects of ripening, such as chlorophyll degradation and fruit softening, are controlled or at least partially controlled by ethylene (Goldschmidt et al., 1993; Wills and Kim, 1995). Ethylene is biosynthesized from methionine via a welldefined pathway in which 1-aminocyclopropane-1-carboxylate (ACC) synthase (ACS) and ACC oxidase (ACO) function as key enzymes. Fruit ripening: Ripening is defined as changes that occur from the latter stages of growth and development through the early stages of senescence and result in characteristic aesthetic and/or food quality (Watada et al., 1984). It is a highly co-ordinated, genetically programmed, and an irreversible phenomenon involving a series of physiological, biochemical, and organoleptic changes that lead to the development of a soft and edible ripe fruit with desirable quality attributes. A wide spectrum of biochemical changes such as increased respiration, chlorophyll degradation, biosynthesis of carotenoids, anthocyanins, essential oils, and flavor and aroma components, increased activity of cell wall-degrading enzymes, and a transient increase in ethylene production are some of the major changes involved during fruit ripening (Brady, 1987). The color change during fruit ripening is due to the unmasking of previously present pigments by degradation of chlorophyll and dismantling of the photosynthetic apparatus and synthesis of different types of anthocyanins and their accumulation in vacuoles, and accumulation of carotenoids such as ÃŽÂ ²-carotene, xanthophyll esters, xanthophylls, and lycopene (Tucker and Grierson, 1987; Lizada, 1993). The increase in flavor and aroma during fruit ripening is attributed to the production of a complex mixture of volatile compounds such as ocimene and myrcene (Lizada, 1993), and degradation of bitter principles, flavanoids, tannins, and related compounds (Tucker and Grierson, 1987). The taste development is due to a general increase in sweetness, which is the result of increased gluconeogenesis, hydrolysis of polysaccharides, especially starch, decreased acid-ity, and accumulation of sugars and organic acids resulting in an excellent sugar/acid blend (Lizada, 1993; Grierson, Tucker, and Robertson, 1981; Selvaraj, Kumar, and Pal, 1989). The metabolic changes during fruit ripening include increase in biosynthesis and evolution of the ripening hormone, ethylene (Yang and Hoffman, 1984), increase in respiration mediated by mitochondrial enzymes, especially oxidases and de novo synthesis of enzymes catalyzing ripening specific changes (Tucker and Grierson, 1987). Alteration of cell structure involves changes in cell wall thickness, permeability of plasma membrane, hydration of cell wall, decrease in the structural integrity, and increase in intracellular spaces (Redgwell, MacRae, Hallet, Fischer, Perry, and Harker, 1997). Fruit softening is associated with cell wall disassembly (Seymour and Gross, 1996) and modifications to the pectin fraction are some of the most apparent changes that take place in the cell wall during ripening (Marin-Rodriguez, Orchard, and Seymour, 2002). The general observation is that softening is accompanied by solubilization of pectin, involving the action of enzymes pectinesterase (PE), polygalacturonase (PG) and pectate lyases (PL) (White, 2002) and hydrolysis of starch and other storage polysaccharides (Selvaraj et al., 1989; Fuchs, Pesis and Zauberman, 1980). This notion was supported by reports of changes in cell wall pectic material in ripening mango (Roe and Bruemmer, 1981), tomato (Besford and Hobson, 1972) and pear (Ahmed and Labavitch, 1980). Fruit ripening and ethylene: The gaseous hormone ethylene regulates a number of plant growth and developmental processes, including fruit ripening. Ethylene plays a major role in fruit ripening in a wide range of plant species (Abeles et al., 1992; Lelievre et al., 1997; Giovannoni, 2004). It is a fruit ripening phytohormone, in minute amounts can trigger many events of cell metabolism including initiation of ripening and senescence, particularly in a climacteric fruit. A number of reviews have been published on the role of ethylene in fruit ripening, particularly in mangoes as well as its biogenesis (Adams and Yang, 1979; Kende, 1993). The pathway for ethylene biosynthesis has been elucidated in apple, and other fruits such as avocado, banana, and tomato (Kende, 1993; Yang and Hoffman, 1984). The first step is the conversion of S-adenosylmethionine (SAM) to 1- aminocyclopropane carboxylic acid (ACC) by the enzyme ACC synthase. At the onset of fruit ripening, expression of multiple ACC synthase genes are activat ed, resulting in increased production of ACC. In most cases, it is the ACC synthase activity, which determines the rate of ethylene biosynthesis. ACC is then oxidized to ethylene by ACC oxidase. Potential of ethephon in fruit ripening: Fruit ripening has been described as an oxidative phenomenon that requires a turnover of active oxygen species, such as H2O2 and superoxide anion (Jimenez et al, 2002). Ethephon (2-chloroethylphosphonic acid), releases ethylene in plant tissues, has aroused interest because of its physiological effects in many fruit species (Cooke and Randall, 1968; Warner and Leopold, 1967). The responses to ethephon appear to be mainly caused by the action of ethylene (Anderson, 1968). Now ethephon is widely used in agriculture for promotion of flowering, fruit ripening, defoliation and so on. Orange, grapefruit, tangerine and green lemon fruits dipped in ethephon solutions for a few seconds to several minutes developed satisfactory marketable color in seven to ten days after treatment. (Fuch and Cohen, 1969; Yong et al., 1970). In pomegranates, however pre-harvest application of ethephon decreased the soluble solids, pH and vitamin C content of the fruit juice (Shaybany and Sharifi, 1973). Rouhani and Bassiri (1977) reported that when date fruits were treated with 0, 125, 250, 500, 1000 or 2000 ppm ethephon and stored in sealed bags or bags with 10 holes. The percentage dry weights of pulp and seed, titratable acidity, soluble solids and respiration rates increased, whereas pH, firmness and astringency decreased with greater maturity. The application of ethephon increased respiration and titratable acidity significantly. Although ethephon concentration and bag type affected ripening, their effects were relatively small; endogenous factors controlling ripening were more important. Ethephon application at 1500 ppm shortly after full bloom on Zaghloul and Samani date palms grown in Egypt advanced fruit ripening by about one month (Kamal, 1995). Musa (2001) reported that effectiveness of ethrel in enhancing the fruit ripening of Mishrigi Wad Khatib and Mishrigi Wad Lagi dates grown in Khartoum, Sudan, was 2-3 fold higher by injecting 2ml of ethrel (480 g/l a.v.) into a pit made in the peduncle compared with 1000 ppm of ethrel spraying over the fruit. Preharvest ethrel application significantly increased the Rutab fruit yield per bunch (7 kg) as compared to the control (4.5 kg) and postharvest dipping of fruit at khalal stage in ethrel at 4.2ml/l and abscisic acid at 1.0 mM significantly enhanced the ripening, compared to the control (Awad, 2007). Ethephon accelerates ripening and improves the peel color of the mangoes (Lakshminarayana et al., 1975). Mixture of ethephon, sodium hydro oxide and water, kept in the vicinity of mango fruit, facilitate the ripening in natural way (Sudhakar, 2006). Nair and Singh (2003) reported that fruit quality in terms of TSS, TSS/acid ratio, sugars and eating quality of mango cv. Bocado was found to improve with ethrel at 2000 ppm. Increase in salt concentration progressively increased the Dong/Rutab formation of khadrawi and shamran date cultivars, and addition of acetic acid enhanced the effect, but acetic acid alone was ineffective (Kalra et al., 1977). Ethephon treatment stimulated the decrement of titratable acidity, anthocyanin accumulation and fruit softening four days after treatment in rabbiteye blueberry. The ripening promotion effect of ethephon on total soluble solids content was observed only eight days after treatment. Ethephon treatment did not affect the fruit enlargement during the investigation period. They concluded that ethephon application for rabbiteye blueberry promote the fruit ripening, but the stimulatory effects of ethephon on fruit ripening were different in degree on each ripening characters (Ban et al., 2007). The stimulatory effect of ethephon on blueberry fruit ripening has been reported by some researchers (Eck, 1970; Forsyth et al., 1977; Lewis and Ju, 1993; Warren et al., 1973). The skin color enhancement effect of ethephon has been noted for apple and cranberry (Eck, 1972; Murphey and Dilley, 1988). In Jonagold apple, ethephon application stimulated the anthocyanin accumulation in the skin, but did n ot affect the total soluble solids content, acidity and fruit firmness (Awad and Jager, 2002). From these results, it is concluded that ethephon application for fruit promotes ripening, but the stimulatory effect of ethephon on fruit ripening differs in degree for each fruit ripening character. Ethylene released by the breakdown of Ethrel ® is the cause of softening of fruit and hastens the onset of ripening of several fruits, including mango, as reported by researchers (Rupinder, Poorinima, Pathak, Singh and Dwivedi, 2007). Role of hot water, sodium chloride and acetic acid in fruit ripening: Recently, wide international interest in heat treatment for quality maintenance and disease control has reflected in a range of literatures. With exposure of fresh agricultural commodities to high temperature, heat shock proteins transcripts and protein levels in such commodities have been shown to increase (Lurie, 1998). Further more, a wide range of fruit ripening processes are affected by heat, such as color (Cheng et al, 1988; Tian et al., 1996), ethylene synthesis (Ketsa et al., 1999), respiration (Inaba and Chachin, 1988), fruit softening and cell wall metabolism (Lurie and Nussinovich, 1996), volatile production. Postharvest heat treatment also can reduce chilling injury in many kinds of fruits during subsequent low temperature storage as well as reduce pathogen level and disease development. Agricultural commodities are large and respond differently by applied heat treatment. Inappropriate heat treatment can also lead to ripening acceleration or heat damage (McDonald et al., 1999; Lurie, 1997). The influence of hot water treatment on the ripening/curing of Dhakki dates with 70 oC performed better than 35 and 93 oC furnishing with 55% product yield of acceptable quality. The yield of improved quality product is further increased to 70% on the optimization of treatment time to 3 minutes. They concluded that Dhakki dates does not require to stay on tree beyond fully mature doka stage for want of dong formation and hence saves at least two weeks hang-on period Saleem et al. (2004). When fruits of Khadrawi and Shamran treated with 2% NaCl alone achieved 72 and 75% ripening by weight, similar studies were also conducted on Khadrawi, Shamran, Zaidi and Thoory date varieties at the doka stage. Sodium chloride (0.5-3.0%), actic acid (0.5-2.0%), or sodium chloride at 1.0% + acetic acid. With Khadrawi and Shamran increased concentration of NaCl resulted in a progressive increase in the ripening percentage of fruits (Kalra and Jawand, 1974; Kalra et al., 1977). Shamshiri and Rahemi (19 99) reported that sodium chloride and acetic acid either separately or combined, significantly increased the TSS and reduced fruit firmness and moisture content. Acetic acid at 2% had a better effect on fruit ripening and sodium chloride, but the fruits with sodium chloride were better in appearance. Mirza and Meraj-ud-Din (1988) treated the fruits of Dhakki and Basra cultivars in doka stage with 3% brine solution, 0.25% acetic acid solution and 0.25% citric acid solution for five minutes and sulfuring them for five hours. Different chemical treatments significantly enhanced the ripening percentage of fruits, brine solution was found to be superior ripening agent.

Genealogy of Alfalfa :: Plants Environment Planting History Essays

Genealogy of Alfalfa In this paper on the genealogy of alfalfa I will begin by telling you about the background and history of alfalfa in the United States. Secondly, I will tell you about the different sources of alfalfa germplasm. Next, I will talk about different studies and experiments that have been done to diversify the breeds of alfalfa. Finally, I will tell you about the genetic makeup of alfalfa and what distinguishes it from other popular plants. Alfalfa otherwise known today as the â€Å"Queen of Forage† is thought to have originated in Iran over 2,400 years ago. It was the only forage crop that was cultivated before recorded history therefore the history of its origin isn’t one-hundred percent accurate. The first attempt to grow alfalfa in the United States was recorded in Georgia in the year 1736. The introduction of alfalfa to California came first by Spanish settlers and later by Europeans. The Europeans were headed to California during the gold rush. They obtained alfalfa seed when sailing around South America. Alfalfa flourished in the western states because of its favorable climate. Because alfalfa has a good yield, is palatable, and has a high value of nutrition. Word spread and so did the planting. Alfalfa then spread eastward to the Midwestern states. The distribution of alfalfa to states east of the Mississippi river was a failure due to its acid soils, plant disease, and humidity. Most of the genetic diversities of alfalfa come from nine germplasm sources. These nine germplasm sources are M. falcate, M. varia, Turkistan, Flemish, Chilean, Peruvian, Indian, and African. According to Barnes, Bingham, Murphy, Hunt, Beard, Skrdla, and Teubar â€Å"M. falcata has orange-yellow flowers and an early fall dormancy therefore it is known to have a heavy first cutting and a light second cutting. It also has some bacterial wilt and foliar disease resistances. Strains were usually classified as M. varia because they had variegated flower colors and variable pod shapes. M. varia sources were introduced to South Dakota in 1907 as seed from a single hybrid plant found in Russia. These sources are winter hardy, more vigorous than M. falcata and are susceptible to bacterial wilt. Turkistan alfalfas have been described as poor seed producers, susceptible to leaf diseases, and resistant to many insects and crown and root disease. They vary in winter hardiness from moderately hardy to hardy.

Leonardo Da Vinci :: essays research papers fc

Leonardo Da Vinci was born on April 14, 1452 in the town of Vinci near Florence Italy. He kept the name of his town for his last name. He lived during the fifteenth century, a period when the people of Europe were becoming interested in art. This period of time was known as the Renaissance period. Leonardo Da Vinci was very talented. He was a great artist, but he became famous because he was able to do so many other things. He was an architect, a musician, inventor, sculptor, scientist, and mathematician. His artistic talent revealed its self early in his life. When he was about 15 years old Leonardo's father took him to Florence Italy, to train as a painter and sculptor in the studio of Andrea del Verroccho. He studied with this master until the age of twenty five. At this point, he set up his own business and was famous for being a painter and a man of science. As a scientist, he observed everything he could in nature. Leonardo used what he learned from nature and science to make h is paintings look real. He drew and took many notes of what he observed. His notes were written backwards, probably because he didn't want people to read about his discoveries and observations. In order to read Leonardo's notes, one has to hold them up to a mirror. In 1472 he entered a painters' guild. His earliest extensive works date back to this time. In 1482 Da Vinci worked for Duke Lodovico Sforza in Milan for 18 years. He fulfilled the position as court artist, but also worked as an engineer and architect. While in Milan Leonardo developed more theories about painting. Leonardo believed that knowledge should be based on observation. He believed that observation led to understanding, and artists had an obligation to record this understanding by painting accurate images. He made sketches of everything around him. This caused him to make a master plan, his plan was to record the structure of every building in the world. He believed that this would uncover laws of harmony and prop ortion. In the fall of 1499 Leonardo left France and headed to Florence. There he painted paintings such as, Battle of Anghiari a mural that was painted for the Council Chamber of Town Hall, the famous portrait named the Mona Lisa, and Leda and the Swan.

Pharmacy Marketing Plan Essay

The Discount Pharmacy is a brick and mortar and mail order pharmacy that sells prescription medication at lower prices than other pharmacies. The Discount Pharmacy is able to sell at reduced prices through the use of operating efficiencies and the elimination of unnecessary services for customers that self pay their drugs. The Discount Pharmacy does not accept insurance payments which disrupt the cash flow. By having a larger percentage of their business serviced by their mail order arm, The Discount Pharmacy is able to gain economies of scale by selling larger quantities of drugs with less labor required per order. As more and more Americans are on a continuous prescription to medicine, this trend will lend itself to rapid growth as customers can mail order larger quantities of drugs that they will need over time. Additionally, many insurance companies offer an economic incentive for medicine to be purchased mail order in quantity, saving the insurance company money. This factor will also help boost The Discount Pharmacy to profitability. The Pharmacy will increase its market share through targeted advertising to increase the number customers who are looking to save money on a pricey, necessary expense. Pharmacy Marketing Plan The Discount Pharmacy Situation Analysis The Discount Pharmacy is in the first year of business as a start-up operation. The Pharmacy believes that the market demand for their services will be great and are convinced that a cohesive marketing strategy is required for The Pharmacy. The Pharmacy offers a wide range of prescription medicine for pick up at their store front or it can be distributed by mail order. The Pharmacy’s prices are far better than most pharmacies so their services will be attractive for people that just need to buy their medicine at good prices and do not need their hands held during the process. Market Summary The Discount Pharmacy posesses good information regarding their market and the target segments that they wish to serve. The Pharmacy will leverage this information to better understand who is served, their specific needs, and how The Pharmacy can better serve them. Market Needs The Discount Pharmacy is providing the market with a source of discounted drugs. This market need is important as many Americans are faced with the dilemma of using their limited income on food or meds. The Discount Pharmacy seeks to fulfill the following benefits that are important to their customers. * Selection: The Pharmacy offers a wide range of medication, both originals as well as generic alternatives. * Accessibility: Products are distributed through their conveniently-located store front, or can be shipped within the U.S. * Customer service: The Pharmacy recognizes the value of having outstanding customer service. By exceeding all of the customer’s expectations, they are ensuring repeat customers and many referrals. * Pricing: The Discount Pharmacy’s prices will be noticeably better than local pharmacies. Market Trends The market trend for pharmacies reinforces consolidation. The whole medical industry (including doctors, pharmaceutical companies) has pressure being applied to them from different sides to achieve cost efficiencies and to decrease the cost of the various products/services. Looking specifically at pharmacies, over the last eight years, there has been widespread consolidation, done to a large degree to achieve costs efficiencies. Now insurance companies are adding pressure to decrease costs since they are a main party in the payment for meds. The Discount Pharmacy is able to coexist in this consolidation environment by achieving cost efficiencies through their unique business model of mail order service and a decrease in the normal pharmacist offered services. Market Growth In 2000, the global pharmaceutical industry as a whole was a $897 billion dollar industry. The industry is forecasted to continue its record growth. This growth can be attributed to several factors, the underling driver is scientific progress. As our scientific community continues to make breakthroughs in medical applications, people become more and more reliant on medication to lengthen and improve their quality of life. American society in particular has become increasingly reliant on medication. This conclusion seems to be fairly intuitive as many individuals have a vested interest in living longer and more comfortably. This demand applies pressure to the scientists and pharmaceutical companies who are always on the lookout for the next big blockbuster drug which will ensure profitable returns. While America remains as the largest consumer of medication in the world, to a large degree based on the simple quantitative measurement of GNP, it is reasonable to expect that the retail distribution of these drugs will achieve extraordinary growth rates if they are employing creative business models or if they are one of the â€Å"giants.† SWOT Analysis The following SWOT analysis captures the key strength and weaknesses within the company, and describes the opportunities and threats facing The Discount Pharmacy. Strengths * A unique, current business-environment-appropriate business model. * Excellent staff who are highly trained and very customer attentive. * Great prices. * The ability to scale rapidly for the mail order side of the business. Weaknesses * The lack of visibility and brand equity of a start-up business. * Lack of true experience running a mail order outfit. * Government intervention/regulation into medicine is possible. Opportunities * Outside pressure on consumers to purchase meds mail order. * The constant growth of the number of people taking medication. * Newly formed alliances of insurance companies and mail order pharmacies. Threats * The entry into the mail order market by an established company. * Regulatory legislation that curtails the mail order medicine industry. * Some event that cripples interstate commerce in regards to shipping. Competition Competition takes many different forms in the pharmacy industry. * Chain pharmacies: These are state or national chains such as Rite-Aid. The advantage to these chains are better prices through economies of scale as well as personalized service. The personalized service takes the form of the chain having a record of your medication purchases as well as any allergies that you have disclosed to them. * Local pharmacies: These are the pharmacies where you typically know the pharmacists and they know your medical history. This option is high in personalized service and convenience, and high in price. * Mail order and Internet pharmacies: These are similar to The Discount Pharmacy. * Canadian pharmacies: These pharmacies are located in Canada where the cost of drugs is lower than in the U.S. These pharmacies can be accessed through mail order, the Internet, or via travel. Recently there has been the trend for trips arranged for senior citizens in northern states to travel up to Canada for the day to pick up their meds. Product Offering The Discount Pharmacy offers a wide range of prescription drugs to patients based in Oregon and nationally. Both generics and name brands are offered. The customer needs to either mail in the prescription, fax it, or email it. Once it is received and payment arrangements are complete, the meds will be sent out to the customer via U.S.P.S. or U.P.S. Local customers may stop by the store front to pick up the medications contemporaneously. The Discount Pharmacy will only service customers who self pay. The self pay customers will be attracted to The Discount Pharmacy because of their superior prices. For many Americans that do not have drug plans, including the vast majority of Americans over 65, a discount on drugs is very welcome on today’s increasingly tight monthly budgets. The Discount Pharmacy will be able to survive on lower margins due to operating efficiencies gained through mail order and not accepting insurance policy drug plans. With each order a printout will accompany the medications that will provide directions on how to take the medications, other drug that should be avoided concurrently, and other useful information. Often times this information is communicated personally by the pharmaceutical technician. The Discount Pharmacy will be using computer printouts from industry software to reduce the cost of providing this information. Note: While the term â€Å"self pay† is typically associated with the notion that the customer is paying for the medication out of pocket without insurance, it is used in this context as the customer paying for the medications upfront by themselves regardless if they have insurance. They may be paying for the drugs out of pocket, or they may be paying for the medications upfront and then requesting their insurance companies drug plan to reimburse them later. Keys to Success The keys to success are: * Repeat customers. * Low overhead and operating costs. * Superior prices and service. Critical Issues The Discount Pharmacy is still in the speculative stages as a start-up business. Its critical issues are to continue to take a modest fiscal approach, expanding at a reasonable rate, not for the sake of expansion in itself, but because prudent economic analysis dictates to  Pharmacy Marketing Plan The Discount Pharmacy Marketing Strategy The Discount Pharmacy will have different marketing strategies for the two different segmented groups that they wish to reach. The walk-in customers will be targeted through advertisements in the local paper, â€Å"The Oregonian.† The advertisements will raise visibility for The Discount Pharmacy and their discounted prices. As the price of medication continues to skyrocket, The Discount Pharmacy will appeal to local people as a way to try to contain these rising costs. The mail order customers will be targeted through an advertising campaign in magazines and newsletters that have an older (over 55) crowd that regularly needs medication and knows in advance what their needs are. One of the main newsletters that The Discount Pharmacy will be visible in is the American Association of Retired Persons (A.A.R.P) monthly newsletter.

The Host Chapter 32: Ambushed

The caves were quiet; the sun had not yet risen. In the big plaza, the mirrors were a pale gray with the coming dawn. My few clothes were still in Jamie and Jared's room. I snuck in, glad that I knew where Jared was. Jamie was sound asleep, curled into a tight ball in the top corner of the mattress. He didn't usually sleep so compactly, but he had good reason to at the moment. Ian was sprawled across the rest of the space, his feet and hands hanging off the edges, one appendage to each of the four sides. For some reason, this was hysterical to me. I had to put my fist in my mouth to choke back the laughter as I quickly snatched up my old dirt-dyed T-shirt and shorts. I hurried into the hall, still stifling the giggles. You're slaphappy, Melanie told me. You need some sleep. I'll sleep later. When†¦ I couldn't finish the thought. It sobered me instantaneously, and everything was quiet again. I was still rushing as I headed for the bathing room. I trusted Doc, but†¦ Maybe he would change his mind. Maybe Jared would argue against what I wanted. I couldn't be all day. I thought I heard something behind me when I reached the octopus-like juncture where all the sleeping halls met. I looked back, but I couldn't see anyone in the dim cave. People were beginning to stir. Soon it would be time for breakfast and another day of work. If they'd finished with the stalks, the ground in the east fields would need to be turned. Maybe I would have time to help†¦ later†¦ I followed the familiar path to the underground rivers, my mind in a million other places. I couldn't seem to concentrate on anything in particular. Every time I tried to focus on a subject-Walter, Jared, breakfast, chores, baths-some other thought would pull my head away in seconds. Melanie was right; I needed to sleep. She was just as muddled. Her thoughts all spun around Jared, but she could make nothing coherent of them, either. I'd gotten used to the bathing room. The utter blackness of it didn't bother me anymore. So many places were black here. Half my daylight hours were lived in darkness. And I'd been here too many times. There was never anything lurking under the water's surface, waiting to pull me under. I knew I didn't have time to soak, though. Others would be up soon, and some people liked to start their day clean. I got to work, washing myself first, then moving on to my clothes. I scrubbed at my shirt fiercely, wishing I could scrub out my memory of the past two nights. My hands were stinging when I was done, the dry cracks on my knuckles burning worst of all. I rinsed them in the water, but it made no noticeable difference. I sighed and climbed out to get dressed. I'd left my dry clothes on the loose rocks in the back corner. I kicked a stone by accident, hard enough to hurt my bare foot, and it clattered loudly across the room, bouncing off the wall and landing with a plunk and a gurgle in the pool. The sound made me jump, though it wasn't all that loud next to the roar of the hot river in the outer room. I was just shoving my feet into my scruffy tennis shoes when my turn was up. â€Å"Knock, knock,† a familiar voice called from the dark entry. â€Å"Good morning, Ian,† I said. â€Å"I'm just done. Did you sleep well?† â€Å"Ian's still sleeping,† Ian's voice answered. â€Å"I'm sure that won't last forever, though, so we'd best get on with this.† Splinters of ice pinned my joints in place. I couldn't move. I couldn't breathe. I'd noticed it before, and then forgotten it in the long weeks of Kyle's absence: not only did Ian and his brother look very much alike, but-when Kyle spoke at a normal volume, which so rarely happened-they also had exactly the same voice. There was no air. I was trapped in this black hole with Kyle at the door. There was no way out. Keep quiet! Melanie shrieked in my head. I could do that. There was no air to scream with. Listen! I did as I was told, trying to focus in spite of the fear that stabbed through my head like a million slender spears of ice. I couldn't hear anything. Was Kyle waiting for a response? Was he sneaking around the room in silence? I listened harder, but the rush of the river covered any sounds. Quick, grab a rock! Melanie ordered. Why? I saw myself crashing a rough stone against Kyle's head. I can't do it! Then we're going to die! she screamed back at me. I can do it! Let me! There has to be another way, I moaned, but I forced my ice-locked knees to bend. My hands searched the darkness and came up with a large, jagged rock and a handful of pebbles. Fight or flight. In desperation, I tried to unlock Melanie, to let her out. I couldn't find the door-my hands were still my own, clutched uselessly around the objects I could never make into weapons. A noise. A tiny splash as something entered the stream that drained the pool into the latrine room. Only a few yards away. Give me my hands! I don't know how! Take them! I started to creep away, close to the wall, toward the exit. Melanie struggled to find her way out of my head, but she couldn't find the door from her side, either. Another sound. Not by the far stream. A breath, by the exit. I froze where I was. Where is he? I don't know! Again, I could hear nothing but the river. Was Kyle alone? Was someone waiting by the door to catch me when he herded me around the pool? How close was Kyle now? I felt the hairs on my arms and legs standing on end. There was some kind of pressure in the air, as though I could feel his silent movements. The door. I half turned, easing back in the direction I'd come, away from where I'd heard the breath. He couldn't wait forever. The little he'd said told me he was in a hurry. Someone could come at any time. Odds were on his side, though. There were fewer who would be inclined to stop him than there were who might think this was for the best. And of those inclined to stop him, even fewer who'd have much of a chance of doing that. Only Jeb and his gun would make a difference. Jared was at least as strong as Kyle, but Kyle was more motivated. Jared would probably not fight him now. Another noise. Was that a footstep by the door? Or just my imagination? How long had this silent standoff lasted? I couldn't guess how many seconds or minutes had passed. Get ready. Melanie knew that the stalling would soon be at an end. She wanted me to clench the rock tighter. But I would give flight a chance first. I would not be an effective fighter, even if I could bring myself to try. Kyle was probably twice my weight, and he had a much longer reach. I raised the hand with the pebbles and aimed them toward the back passage to the latrine. Maybe I could make him think that I was going to hide and hope for rescue. I threw the handful of small stones and shied away from the noise when they clattered against the rock wall. The breath at the door again, the sound of a light footfall headed toward my decoy. I edged as quietly along the wall as I could. What if there are two? I don't know. I was almost to the exit. If I could just make the tunnel, I thought I could outrun him. I was lighter and fast†¦ I heard a footstep, very clearly this time, disrupting the stream in the back of the room. I crept faster. A gigantic splash shattered the tense standoff. Water pelted my skin, making me gasp. It spattered against the wall in a wave of wet sound. He's coming through the pool! Run! I hesitated just a second too long. Big fingers clutched at my calf, my ankle. I yanked against the pull, lurching forward. I stumbled, and the momentum that threw me down to the floor made his fingers slip. He caught my sneaker. I kicked it off, leaving it in his hand. I was down, but he was down, too. It gave me enough time to scramble forward, ripping my knees against the rough stone. Kyle grunted, and his hand clutched at my naked heel. There was nothing to catch hold of; I slid free again. I wrenched myself forward, pulling to my feet with my head still down, every second in danger of falling again because my body was moving almost parallel to the floor. I kept my balance through sheer force of will. There was no one else. No one to catch me at the exit to the outer room. I sprinted forward, hope and adrenaline surging in my veins. I burst into the river room at full speed, my only thought to reach the tunnel. I could hear Kyle's heavy breath close behind but not close enough. With each step, I pushed harder against the ground, throwing myself ahead of him. Pain lanced through my leg, crumpling it. Over the babble of the river, I heard two heavy stones hit the ground and roll-the one I'd been clutching and the one he'd thrown to cripple me. My leg twisted under me, spinning me backward to the ground, and in the same second he was on top of me. His weight knocked my head against the rock in a ringing blow and pinned me flat against the floor. No leverage. Scream! The air blew out of me in a siren of sound that surprised us all. My wordless shriek was more than I'd hoped for-surely someone would hear it. Please let that someone be Jeb. Please let him have the gun. â€Å"Uhng!† Kyle protested. His hand was big enough to cover most of my face. His palm mashed against my mouth, cutting off my scream. He rolled then, and the motion so took me by surprise that I had no time to try to find an advantage in it. He pulled me swiftly over and under and over his body. I was dizzy and confused, my head still spinning, but I understood as soon as my face hit the water. His hand locked on the back of my neck, forcing my face into the shallow stream of cooler water that wound its way into the bathing pool. It was too late to hold my breath. I'd already inhaled a mouthful of water. My body panicked when the water hit my lungs. Its flailing was stronger than he'd expected. My limbs all jerked and thrashed in different directions, and his grip on my neck slipped. He tried to get a better hold, and some instinct made me pull myself into him rather than away, as he was expecting. I only pulled half a foot closer to him, but that got my chin out of the stream, and enough of my mouth to choke some of the water back out and drag in a breath. He fought to push me back into the stream, but I wriggled and wedged myself under him so that his own weight was working against his goal. I was still reacting to the water in my lungs, coughing and spasming out of control. â€Å"Enough!† Kyle growled. He pulled himself off me, and I tried to drag myself away. â€Å"Oh, no, you don't!† he spit through his teeth. It was over, and I knew it. There was something wrong with my injured leg. It felt numb, and I couldn't make it do what I wanted. I could only push myself along the floor with my arms and my good leg. I was coughing too hard to do even that well. Too hard to scream again. Kyle grabbed my wrist and yanked me up from the floor. The weight of my body made my leg buckle, and I slumped into him. He got both my wrists in one hand and wrapped the other arm around my waist. He pulled me off the floor and into his side, like an awkward bag of flour. I twisted, and my good leg kicked against the empty air. â€Å"Let's get this over with.† He jumped over the smaller stream with a bound and carried me toward the closest sinkhole. The steam from the hot spring washed my face. He was going to throw me into the dark, hot hole and let the boiling water pull me into the ground as it burned me. â€Å"No, no!† I shouted, my voice too hoarse and low to carry. I writhed frantically. My knee knocked against one of the ropy rock columns, and I hooked my foot around it, trying to yank myself out of his grip. He jerked me free with an impatient grunt. At least that loosened his hold enough that I could make one more move. It had worked before, so I tried it again. Instead of trying to free myself, I twisted in and wrapped my legs around his waist, locking the good ankle around the bad, trying to ignore the pain so that I could get a good hold there. â€Å"Get off me, you -† He fought to knock me loose, and I jerked one of my wrists free. I wrapped that arm around his neck and grabbed his thick hair. If I was going into the black river, so was he. Kyle hissed and stopped prying at my leg long enough to punch my side. I gasped in pain but got my other hand into his hair. He wrapped both arms around me, as if we were embracing rather than locked in a killing struggle. Then he grabbed my waist from both sides and heaved with all his strength against my hold. His hair started to come out in my hands, but he just grunted and pulled harder. I could hear the steaming water rushing close by, right below me, it seemed. The steam billowed up in a thick cloud, and for a minute I couldn't see anything but Kyle's face, twisted with rage into something beastlike and merciless. I felt my bad leg giving. I tried to pull myself closer to him, but his brute strength was winning against my desperation. He would have me free in a moment, and I would fall into the hissing steam and disappear. Jared! Jamie! The thought, the agony, belonged to both Melanie and me. They would never know what had happened to me. Ian. Jeb. Doc. Walter. No goodbyes. Kyle abruptly jumped into the air and came down with a thud. The jarring impact had the effect he wanted: my legs came loose. But before he could take advantage, there was another result. The cracking sound was deafening. I thought the whole cave was coming down. The floor shuddered beneath us. Kyle gasped and jumped back, taking me-hands still locked in his hair-with him. The rock under his feet, with more cracking and groaning, began to crumble away. Our combined weight had broken the brittle lip of the hole. As Kyle stumbled away, the crumbling followed his heavy steps. It was faster than he was. A piece of the floor disappeared from under his heel, and he went down with a thud. My weight pushed him back hard, and his head smacked sharply against a stone pillar. His arms fell away from me, limp. The cracking of the floor settled into a sustained groan. I could feel it shiver beneath Kyle's body. I was on his chest. Our legs dangled above empty space, the steam condensing into a million drops on our skin. â€Å"Kyle?† There was no answer. I was afraid to move. You've got to get off him. You're too heavy together. Carefully-use the pillar. Pull away from the hole. Whimpering in fear, too terrified to think for myself, I did as Melanie ordered. I freed my fingers from Kyle's hair and climbed gingerly over his unconscious form, using the pillar as an anchor to pull myself forward. It felt steady enough, but the floor still moaned under us. I pulled myself past the pillar and onto the ground beyond it. This ground stayed firm under my hands and knees, but I scrambled farther away, toward the safety of the exit tunnel. There was another crack, and I glanced back. One of Kyle's legs drooped farther down as a rock fell from beneath it. I heard the splash this time as the chunk of stone met the river below. The ground shuddered under his weight. He's going to fall, I realized. Good, Melanie snarled. But†¦! If he falls, he can't kill us, Wanda. If he doesn't fall, he will. I can't just†¦ Yes, you can. Walk away. Don't you want to live? I did. I wanted to live. Kyle could disappear. And if he did, there was a chance that no one would ever hurt me again. At least not among the people here. There was still the Seeker to consider, but maybe she would give up someday, and then I could stay here indefinitely with the humans I loved†¦ My leg throbbed, pain replacing some of the numbness. Warm fluid trickled down my lips. I tasted the moisture without thinking and realized it was my blood. Walk away, Wanderer. I want to live. I want a choice, too. I could feel the tremors from where I stood. Another piece of floor splashed into the river. Kyle's weight shifted, and he slid an inch toward the hole. Let him go. Melanie knew better than I what she was talking about. This was her world. Her rules. I stared at the face of the man who was about to die-the man who wanted me dead. With him unconscious, Kyle's face was no longer that of an angry animal. It was relaxed, almost peaceful. The resemblance to his brother was very apparent. No! Melanie protested. I crawled back to him on my hands and knees-slowly, feeling the ground with care before each inch I moved. I was too afraid to go beyond the pillar, so I hooked my good leg around it, an anchor again, and leaned around to wedge my hands under Kyle's arms and over his chest. I heaved so hard I nearly pulled my arms from their sockets, but he didn't move. I heard a sound like the trickle of sand through an hourglass as the floor continued to dissolve into tiny pieces. I yanked again, but the only result was that the trickle sped up. Shifting his weight was breaking the floor faster. Just as I thought that, a large chunk of rock plummeted into the river, and Kyle's precarious balance was overthrown. He began to fall. â€Å"No!† I screamed, the siren bursting from my throat again. I flattened myself against the column and managed to pin him to the other side, locking my hands around his wide chest. My arms ached. â€Å"Help me!† I shrieked. â€Å"Somebody! Help!†
