He has since written many works of prose and poetry. “His literary works, spanning a variety of genres(体裁), comprises about 40 plays and a wealth of novels, poetry collections, essays, children’s books and translations,” said Anders Olsson, chairman of the Nobel Committee for Literature.Jon Fosse draws inspiration from his rural living environment and personal struggles, which have deeply influenced his distinctive writing style. Growing up in a small coastal village, Fosse was immersed in the beauty of nature and the vastness of the sea, which filled him with a sense of solitude and introspection(内省) that is reflected in his works. Fosse’s writing discussed themes of desolateness(孤独,苍凉), longing, and the search for meaning in life. Additionally, his battles with depression have enabled him to explore the depths of human emotions and existential des-pair.“He touches you so deeply when you read his works,” said Anders Olsson. “What is special about him is the closeness in his writing. It touches your deepest feelings-anxieties, insecurities, questions of life and death-which are things that every human being actually faces from the very beginning. In that sense I think he reaches very far and there is a sort of a universal impact of every-thing that he writes-it has appeal to this basic humanity.”Fosse is the first-ever laureate writing in Nynorsk, one of the two official languages of Norwegian, but only used by just 10% of the population. As The Guardian writes, “Many Nynorsk speakers see Fosse ‘as a kind of national hero’ for his championing of the language.” Fosse’s recognition on a global stage promotes the visibility and importance of Nynorsk as a writtenstandard. It will attract more attention to Nynorsk literature, inspire and encourage Nynorsk speakers to continue preserving and promoting their linguistic(语言的) heritage.4.What do we know about Jon Fosse from paragraph 2?A.His most popular work is the play Red, Black.B.He accomplished various genres of literature works.C.Many famous plays are the inspiration for his writing.D.His language skills earned him the Nobel Prize in Literature.5.What does paragraph 3 mainly talk about?A.Jon Fosse’s tough experiences.B.Jon Fosse’s motivation for writing.C.The major themes of Jon Fosse’s works.D.The effect of Jon Fosse’s life on his writing style.6.What is special about Jon Fosse’s works according to Anders Olsson?A.They explore the meaning of life.B.They touch human’s deepest emotions.C.They show the bond between humans and nature.D.They appeal to readers to focus on personal feelings.7.What contribution of Jon Fosse is mentioned in the last paragraph?A.He explains the importance of linguistic diversity.B.He has improved the international status of Norway.C.He promotes the development and preservation of Nynorsk.D.He shapes the basic writing standard of Norwegian literature.It’s one of the most common questions adults ask children: what do you want to be when you grow up? Although childhood is supposed to be fun, kids also discuss important topics regarding their futures. Now, a new study finds that children who set big goals regarding their future status and education often set themselves up for success as they age.The findings, published in the Journal of Personality and Social Psychology, are the first to reveal a connection between life goal development and future success in school or the workplace. Rodica Damian, an associate professor of psychology at the University of Houston, and otherresearchers discovered that as children grow up, their goals naturally begin to change. However, as some childhood goals fall away, other goals related to a family stay strong. These include being close to relatives, building more friendships or finding a romantic partner, and even becoming more involved in your community or helping others.During the study, researchers compared how their goals evolved as children moved from adolescence to adulthood and how a person’s goals impacted their success in school and as an employee later on. Overall, a child’s goals focusing on their education and future status were the most consistent predictors (预测因素) of income in adulthood. Simply put, when a child dreams big about doing well in school or achieving great success as an adult, these goals accurately paint a picture of how successful these children will be. So, the message is simple: dream big and dream of success, kids! Those goals can drive you to success when you grow up!“Our work proves a strong connection between a child’s life goals, educational achievement, and future occupational outcomes. This information is valuable for parents and educators who can use it to encourage children to set ambitious goals. Additionally, it helps develop strategies to support individuals in achieving their goals and reaching their full potential,” Damian concludes. 8.What does the study mainly focus on?A.Why children change their dreams over time.B.Whether childhood goals relate to future success.C.Whether early education determines future career.D.How childhood experiences impact a person’s choice.9.Which of the following goals remains strong as children grow up?A.Connecting with others.B.Achieving academic success.C.Hunting for a high-salary jobD.Improving personal social status.10.What message does the author convey in paragraph 3?A.Dreaming big is potentially associated with success.B.Childhood achievement s greatly affect future careers.C.Educational goals may be more achievable than others.D.Adjusting goals can create new opportunities for success.11.What is the purpose of the last paragraph?A.To explain the purpose of the study.B.To offer suggestions for future studies.C.To stress the significance of the study.D.To point out the limitations of the study.Spiders are master builders, expertly turning silk into complex 3D webs that serve as their home and hunting ground. To gain a deeper understanding of their world, scientists have translated the structure of a spider’s web into music.“The spider lives in an environment of vibrating (振动的) strings,” says Markus Buehler, the project’s principal investigator. “They don’t see very well, so they perceive their surroundings by detecting vibrations, which have different frequencies.” Such vibrations occur, for example, when the spider stretches a strand of silk during construction or when the wind or a trapped fly moves the web.The researchers scanned a natural spider web to capture 2D cross-sections and reconstructed its 3D network using a mathematical model. They assigned different frequencies of sound to strands of the web, creating musical “notes” that they combined in patterns based on the web’s 3D structure to generate music. Then they made a harp-like (像竖琴的) virtual instrument and played the spider web music in several live performances around the world, creating an inspiring harmony of art and science.To gain insights into how spiders build webs, the researchers also scanned a web during construction, transforming each stage into music with different sounds. “The spider’s way of ‘printing’ the web is remarkable because no support material is used, as is often needed in current 3D printing methods,” Buehler says. This knowledge could help develop new 3D printers that work like spiders, enabling them to construct complex structures without using additional materials for support.The team is also interested in learning how to communicate with spiders in their own language. They recorded web vibrations produced when spiders performed different activities, such as building a web, communicating with other spiders or sending signals to admirers. “Now we’re trying to generate signals to basically speak the language of the spider,” Buehler says. “If we expose them to certain patterns of vibrations, can we affect what they do or can we begin to communicate with them? Those are really thrilling ideas, and I believe they could be achieved inthe near future.”12.What do we know about spiders?A.They have good eyesight.B.They adapt to surroundings quickly.C.They spin a web similar to a musical structure.D.They sense the environment through vibrations.13.What is paragraph 3 mainly about?A.Steps to create spider web music.B.Ways to recreate a web’s 3D network.C.Challenges of combining music with science.D.The potential applications of 3D printing methods.14.What do the underlined words “This knowledge” in paragraph 4 refer to?A.3D printers can construct complex structures.B.Spiders’ vibration patterns vary with activities.C.Spiders build webs without using additional materials.D.The web-building process can be translated into music.15.What is Buehler’ attitude towards communicating with spiders?A.Hopeful.B.Doubtful.C.Uncertain.D.Disapproving.The storms in our lives often leave behind gifts if we open our eyes to see them. As the skies clear and you start to emerge from the loss, look for the silver linings. 16 Going through difficulties requires courage and determination. You have to dig deep and find the strength you didn’t know you possessed to overcome the challenges. 17 That self-knowledge and confidence in your abilities will serve you well going forward.Coming out the other side of trouble sometimes gives you a fresh outlook. Priorities shift.18 You have a deeper appreciation for life’s simple moments and clarity about what matters. Use that insight to guide your choices and cherish each day. 19 The old way of doing things no longer works, so you must rebuild and reimagine your life. Though change is hard, it opens up possibilities for new growth and exciting adventures. Look at this as a chance for a fresh start. You can pursue new dreams or make along-wished-for switch in your situation. The future isunwritten.Your struggles and pain have given you understanding for what others maybe going through in their own lives. You now recognize the suffering of people around you and desire to help ease their burdens. Use your experience to be there for friends and family members facing difficulties.20 Your sympathy can make a real difference.A.Dramatic changes often lead to transformation.B.They’re there if you are bent on searching for them.C.Offer a listening ear and share your story with them.D.Storms shape us, but the silver linings make us suffer.E.What seemed important before now pales in comparison.F.Now you know you have the inner power to weather storms.G.This new perspective removed previous doubt about yourself.二、完形填空In my early thirties, I decided to climb Mount Kilimanjaro, the highest mountain in Africa at 5, 895meters above sea level.After months of preparation, I started my great 21 .

英文回复信范例-Response-Letter
Dear Editors and Reviewers,Thank you for your letter and comments on our manuscript titled “Temporal variability in soil moisture after thinning in semi-arid Picea crassifolia plantations in northwestern China” (FORECO_2017_459). These comments helped us improve our manuscript, and provided important guidance for future research.We have addressed the editor’s and the reviewers’comments to the best of our abilities, and revised text to meet the Forest Ecology and Management style requirements. We hope this meets your requirements for a publication.We marked the revised portions in red and highlighted them yellow in the manuscript. The main comments and our specific responses are detailed below:Editor:Please explain how the results in this paper are significantly different from those in Zhu, X., He, Z.B., Du, J., Yang, J.J., Chen, L.F., 2015. Effects of thinning on the soil moisture of the Picea crassifolia plantation in Qilian Mountains. Forest Research. 28, 55–60.)Response:We apologize for our earlier lack of clarity about the differences between our study and those in “Zhu, X., He, Z.B., Du, J., Yang, J.J., Chen, L.F., 2015. Effects of thinning on the soil moisture of the Picea crassifolia plantation in QilianMountains. Forest Research. 28, 55–60”(named “previous article” below). Specifically, we found three main differences in the temporal variability and hydrological responses of soil moisture between our study and the “previous article”.First, the scope of data analysis and use were different:T he “previous article”just applied the one growing season data (from June 28th to October 25th 2013) from the natural forest and the plantations with no thinning and thinned in 20% intensity. In addition, the “previous article” also has not considered the effect of 40% thinning on the soil moisture of the Picea crassifolia plantation. However, in the present study, we applied four years data (from June 27th2012 to October 30th2015 in HD and NF; from January 1th 2014 to October 29th 2015 in MD and LD) from the natural forest and the plantations with no thinning, thinned in 20%, and thinned in 40% intensity to analysis the temporal variability and hydrological responses of soil moisture in semi-arid Picea crassifolia plantations in northwestern China.Second, the content of the research was different: The “previous article”only considered the spatial and temporal dynamic changes of soil moisture, but did not involve the inter-annual, and seasonal dynamic changes of the soil moisture. In the present study, however, not only did we considered the effects of thinning on the spatial and temporal dynamic changes,the inter-annual changes, and seasonal dynamic changes of the soil moisture; but we also considered the changes in soil hydrological response after thinning.Our goals were to understand the changes in soil hydrological response and soil moisture dynamics, and to determine whether thinning management can effectively improve the state of soil moisture in the subalpine Piceacrassifolia plantations in the Qilian Mountains.Third, the research purpose and the result were also different: The mainly purpose of the “previous article”was to preliminary explore the thinning on the plantation forest soil moisture, and they found that the intermediate thinning can significantly increase soil moisture content at the depth of 60 cm. However, they didn’t point out that which or what the thinning intensity or plantation density can be benefit to sustainability of planted forests in these water-limited regions. In this study, not only we did confirmed that the intermediate thinning can significantly increase soil moisture content at the deep soil layer, but we also found that high planting density was the main cause of severe soil moisture deficits in the long-term, and it could be mitigated by 20 - 40% thinning (~3139 trees ha-1).In addition, by investigating the effect of thinning on the soil hydrological response, we found that soil hydrological response may be temporarily modified by thinning according to changes in canopy structure, precipitation properties, and antecedent soil moisture conditions. Soil moisture in natural forest rapidly infiltrated into deep soil, which greatly improved the efficiency of precipitation use. Thinning significantly increased the capacity for soil infiltration, and moderate thinning intensity may be conducive to deep soil-water recharge. Further, according to the global circulation prediction models and trend analysis results and weather patterns, deep VSWC may increase if precipitation patterns shift to produce larger but less frequent rainfall events during the growing season, and this change will benefit growth of the vegetation planted at higher density in this semi-arid region.Reviewer 1I found the topic very interesting. The scientific (experimental) set-up is valid and the data is presented clearly, and analyzed in detail. My detailed comments are all in the attached pdf-file.Response: Thank you for your encouraging remarks and valuable comments. We corrected our text according to your comments submitted in the attached pdf-file. Our responses to your comments are as follows:Comments in attached pdf-file1. Keywords: maybe re-consider “Rainfall”Response:We fully agree that it is necessary to re-consider “Rainfall”in the Keywords section. In addition, the statement of “Rainfall” was corrected as “Soil hydrological response” (L31).2. Ln. 37: Expand, i.e. why are these specific regions water-limited.Response: We apologize for our earlier lack of clarity. To increase clarity, we havere-written this sentence accordingly, and we have corrected “Grassland afforestation is critical in efforts to prevent wide-spread land degradation in arid and semi-arid regions of China (Chen et al., 2008a; Yang et al., 2014). However, sustainability of planted forests is severely limited by soil moisture conditions. Soil moisture is fundamental to sustainability in water-limited ecosystems (Newman et al., 2006; Yang et al., 2014).” as “Grassland afforestation is critical in efforts to prevent wide-spread land degradation in arid and semi-arid regions of China (Chen et al., 2008a; Yang et al., 2014), where rainfall is the main source of soil moisture, and where many vegetation restoration projects were implemented (Li, 2004). However, soil moisture is the most crucial factor to sustainability of planted forests in these water-limited ecosystems (Newman et al., 2006; Yang et al., 2014). (L35-40)”.3. Ln. 47: What is meant by “statistical moments of soil moisture, such as mean and variance”?Response: It is meant that changes to canopy structure due to large-scale clearings or intermediate disturbance events may lead to changes in the mean and the variance of the soil moisture. We amended our text to clarify, and now it reads: “Changes to forest canopy structure due to large-scale harvesting may lead to changes in soil properties, residual tree growth, and the mean and the variance of the soil moisture (Chen et al., 1993; Olchev et al., 2009; He et al., 2013; Kaarakka et al., 2014).” (L48-51).4. Ln. 60: add “ecosystems” (instead of cosystem)Response:The statement of “cosystem” was corrected as “ecosystems” (L62).5. Ln. 68: change “determining” to “affecting”Response:The statement of “determining” was corrected as “affecting” (L71).6. Ln. 71: Expand this sentence a bit. Growing season –where? At the studied region/area?Response: To increase clarity, we have re-written this sentence accordingly (L71-75). And our studied region/area is also experiencing this precipitation patterns, with larger but less frequent rainfall events during the growing season, and more frequent extreme hydrological events.7. Ln. 74–80: Heisler-White, He et al. and Sun et al. →showed where, in what type of ecosystem, how does it relate to the studied one, i.e. elaborate more on how these studies relate to the current one.Response:That was an excellent suggestion, and we have made revisions according to your comments (L78-80, L83, L85-86).The study of Heisler-White et al. (2008)provides a background knowledge of the supply of the precipitation on soil profile. The studies of He et al. (2012) and Sun et al.

A node-splitting algorithm that finds a good heuristic solution to the problem has been developed. In some cases, it is better, for instance, th an Korhonen’s algorithm. Comparison shows that the node-splitting method is comparable to other heuristic methods.An advantage of this algorithm is that the computations of the bead’s movement can be done in parallel, provided that there is a synchronization barrier to update their new positions. This can take advantage of some parallel computers, for example, mapping each bead to a (virtual) processor.The Steiner tree has been shown to be an optimization problem. Neural network has been successfully applied to solve many optimization problems, for example, TSP. Some of these techniques have been discussed. This could be an interesting area for research in the future. It is possible that these techniques can also be applied to solve the SMT if a good mapping of the problem to an appropriate network architecture is found.Part6 Abstract■知识点: 组织架构1.

Data have been collected from archives, interviews, newspapers, and published reports.(结论)This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement.(意义)The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.Part7 References■知识点: Science Reference StyleJournals:1. Y. Shen, Y. P.

《科学探究的精神与方法》高中生英语作文
《科学探究的精神与方法》高中生英语作文The Spirit and Methods of Scientific InquiryScientific inquiry is a systematic process that involves observing, asking questions, and conducting experiments to understand the natural world.It is a fundamental aspect of human progress and development, driving innovation and shaping our understanding of the universe.The spirit of scientific inquiry, which includes curiosity, skepticism, and perseverance, is essential for students to develop a deep appreciation for the scientific method and its applications.The first step in the scientific inquiry process is making observations.This involves using our senses to gather information about the world around us.Observations can be qualitative, describing qualities such as color or texture, or quantitative, involving measurements such as length or weight.It is important for students to learn how to make precise and accurate observations to ensure that their data is reliable.Once observations have been made, the next step is to ask questions.Questions are the foundation of scientific inquiry, as they inspire investigation and lead to further understanding.Students should be encouraged to ask questions about their observations, and to seek answers through research and experimentation.The scientific method is a structured approach to answering questions and testing hypotheses.It involves making a hypothesis, whichis an educated guess about the relationship between variables, and designing experiments to test the hypothesis.Students should learn how to design experiments that control for variables and use randomization to minimize bias.It is also important for students to learn how to analyze data and draw conclusions based on evidence.The spirit of scientific inquiry also includes skepticism, which is the willingness to question assumptions and challenge existing knowledge.Skepticism is crucial for preventing fraud and error in scientific research, and for promoting a culture of intellectual curiosity and open-mindedness.Students should be encouraged to question information and to seek multiple perspectives on any given topic.Finally, the scientific method requires perseverance and resilience.Scientific inquiry can be a lengthy and difficult process, involving many failed attempts and setbacks.Students should learn that failure is a natural part of the scientific process, and that perseverance and persistence are key to success in science and in life.In conclusion, the spirit and methods of scientific inquiry are essential for students to develop a deep appreciation for the scientific process and its applications.By fostering curiosity, skepticism, and perseverance, we can help students to become informed and engaged citizens, who are equipped to contribute to the ongoing development of scientific knowledge and understanding.。

鸟类间的生态竞争英语作文
As a high school student with a keen interest in biology, Ive always been fascinated by the intricate dynamics of nature, especially the ecological competition among birds. This essay aims to delve into the fascinating world of avian interactions, exploring how different bird species compete for resources and coexist in the same environment.Growing up in a suburban area surrounded by lush greenery, Ive had the privilege of observing various bird species from my window. The sight of a majestic eagle soaring high in the sky, or a humble sparrow hopping around on the ground, always fills me with awe. But its not just their beauty that captivates me its the complex relationships they share with each other that truly intrigues me.One of the most evident forms of competition among birds is for food. Birds, like all living creatures, need to eat to survive, and the availability of food can be a scarce resource, especially during harsh seasons. Ive witnessed firsthand how a group of sparrows would aggressively chase away a larger bird, like a crow, from a feeder filled with seeds. This behavior is not just about survival its also about ensuring the survival of their offspring. By monopolizing a food source, these small birds increase their chances of raising healthy, strong young ones.Another form of competition is for nesting sites. Birds are not just picky about what they eat they are also very particular about where they lay their eggs. A safe and secure nesting site is crucial for the survival of their young. Ive observed how a pair of robins would defend their chosen tree hollow from other birds, even going as far as engaging in aerial battles. Thisterritorial behavior is not just about securing a home its also about ensuring the best possible start for their offspring.But competition among birds is not always a zerosum game. There are instances of cooperation and symbiosis that defy the cutthroat nature of survival. For example, some bird species, like the oxpeckers, have evolved to live in harmony with larger animals, such as buffaloes. These small birds feed on ticks and parasites found on the larger animals, providing a valuable service while also securing a meal for themselves. This mutualistic relationship is a beautiful example of how different species can coexist and thrive together.Moreover, the competition among birds can also drive evolutionary adaptations. For instance, the beak shape and size of different bird species have evolved to suit their specific feeding habits. Hummingbirds, with their long, slender beaks, are perfectly adapted to feed on nectar from flowers, while eagles, with their powerful talons, are built for hunting and catching prey. These adaptations not only help individual species survive but also contribute to the overall biodiversity of an ecosystem.However, the ecological competition among birds is not without its challenges. Human activities, such as deforestation and pollution, have disrupted the delicate balance of nature, putting many bird species at risk. The loss of habitat and food sources has forced some birds to compete more intensely for the remaining resources, leading to a decline in their populations.As a high school student, I feel a deep sense of responsibility to protect and preserve the natural world for future generations. By studying and understanding the ecological competition among birds, we can gain valuable insights into the interconnectedness of life and the importance of maintaining a healthy, balanced ecosystem.In conclusion, the ecological competition among birds is a fascinating and complex phenomenon that reflects the struggle for survival in the natural world. By observing and learning from these interactions, we can appreciate the beauty and resilience of life, as well as the importance of conservation efforts to protect our planets biodiversity. As we continue to explore and understand the intricate relationships among bird species, we can also learn valuable lessons about cooperation, adaptation, and the delicate balance of life on Earth.。
中学生自然科学类英语作文
The Magic of Nature: An Exploration forMiddle School StudentsAs middle school students, we are often fascinated by the wonders of the natural world. The beauty and complexity of nature provide a vast canvas for our curiosity and exploration. In this essay, we will delve into the fascinating realm of natural science, uncovering its secrets and celebrating its magnificence.The natural world is a dynamic and interactive system, where every living thing is connected to the other in a web of intricate relationships. The ecosystem, for instance, is a community of living organisms that interact with their environment, maintaining a delicate balance. From the smallest bacterium to the largest elephant, each species plays a crucial role in keeping the system healthy and functioning.Biology, one of the branches of natural science, studies the structure, function, and evolution of living organisms. Through the lens of biology, we can understand how organisms adapt to their environment, how they evolve over time, and how they interact with other species. Forinstance, the chameleon's ability to change its color matches its surroundings, allowing it to camouflage and escape predators. This amazing adaptation is a testament to the power of natural selection and evolution.Physics, another branch of natural science, deals with the fundamental laws of matter and energy. It explores the behavior of matter at the smallest scales, such as atomsand molecules, as well as the largest scales, like the universe itself. The laws of gravity, motion, and electromagnetism, among others, govern the behavior of everything in the universe, from falling apples to orbiting planets.Chemistry, on the other hand, studies the composition, structure, and properties of matter. It delves into the interactions between atoms and molecules, revealing the secrets of compounds and reactions.

一个人走夜路英语作文好开头好结尾全文共3篇示例,供读者参考篇1The Evening Stroll: A Solitary JourneyThe sun had long since disappeared beyond the horizon, casting the world into a somber shade of darkness. As I stepped out into the cool embrace of the night, a sense of trepidation mingled with excitement coursed through my veins. The familiar streets that I had traversed countless times during the day now took on an entirely different persona, morphing into an enigmatic realm where shadows danced and secrets lurked.With each step, the rhythmic sound of my footsteps echoed through the stillness, serving as a metronome to the beating of my heart. The air carried a distinct chill, prompting me to tug my jacket tighter around my frame. Despite the potential perils that lurked in the unknown, an inexplicable allure drew me forward, beckoning me to embrace this solitary journey.As I ventured deeper into the night, the world around me seemed to come alive in unexpected ways. The streetlights cast a warm, amber glow upon the pavement, illuminating pockets ofthe path while leaving others shrouded in mystery. The shadows elongated, stretching across the concrete like tendrils reaching out to ensnare the unwary traveler.In the distance, the muffled sounds of life carried on – the faint rumble of a car engine, the laughter of revelers spilling out from a nearby establishment, the howl of a stray dog echoing through the alleyways. Each noise amplified by the silence, painting a vivid tapestry of the nocturnal symphony that unfolded around me.With each block traversed, my senses heightened, attuned to the subtlest of changes in my surroundings. The scent of jasmine wafted through the air, a fleeting fragrance that teased my olfactory receptors before dissipating into the night. The gentle rustling of leaves in the trees whispered secrets that only the wind could decipher.As I pressed onward, my mind wandered, untethered from the constraints of the day. Thoughts and musings that had been suppressed by the hustle and bustle of daily life now bubbled to the surface, free to roam and explore the vast expanse of my psyche. Questions that had long remained unanswered, dreams that had been tucked away for safekeeping, and aspirations thathad been overshadowed by the demands of the present – all clamored for attention, vying for a moment in the spotlight.With each stride, a profound sense of solitude enveloped me, a cloak that simultaneously offered comfort and ignited a yearning for connection. In the stillness of the night, the world seemed to shrink, condensing into a microcosm where I was the sole inhabitant, free to navigate the labyrinth of my thoughts without fear of interruption or judgment.Yet, as I continued my nocturnal meanderings, a realization dawned upon me: in this solitude, I was not truly alone. The night itself became my companion, a silent observer bearing witness to my journey. The flickering streetlights acted as beacons, guiding my path and reminding me that even in the darkest hours, there was always a glimmer of light to lead the way.As the first hints of dawn began to paint the eastern sky with streaks of vibrant hues, I found myself standing at the threshold of a new day. The night had offered me a respite, a sanctuary where I could explore the depths of my inner world without the distractions of the waking world.With a deep breath, I turned to face the rising sun, its warm rays caressing my face like a gentle embrace. In that moment, I felt a profound sense of gratitude for the solitary journey I hadundertaken, for it had reminded me of the inherent beauty and profundity that can be found in the simplest of experiences – a walk alone in the night.As I retraced my steps, the world around me seemed to have undergone a subtle transformation. The shadows that had once loomed ominously now held a certain allure, their mysteries beckoning me to unravel their secrets on another evening's stroll. The sounds that had once seemed discordant now blended into a harmonious symphony, a nocturnal concerto that celebrated the rhythm of life itself.In the end, the night had offered me far more than a mere respite from the day's demands; it had gifted me with a newfound appreciation for the beauty that can be found in solitude, a renewed sense of wonder at the world that unfolds when the sun slips below the horizon, and a reaffirmation of the power that lies within each of us to embark on our own odysseys of self-discovery.As I approached the familiar threshold of my home, I knew that the night had left an indelible mark upon my soul – a reminder that even in the darkest of hours, there is always a path to be illuminated, a journey to be undertaken, and a world of wonders waiting to be explored.篇2A Solitary Journey into the NightAs the golden rays of the sun bid farewell to the day, the streets come alive with a different kind of energy. Neon lights flicker to life, casting an ethereal glow on the sidewalks, while the hustle and bustle of the daytime crowds gives way to a more subdued, almost mystical ambiance. It's in these twilight hours that I find myself drawn to the beckoning call of the night, embarking on a solitary journey through the city's winding paths.There's something inexplicably alluring about the night, a sense of mystery and possibility that seems to evade the harsh glare of daylight. As I step out into the cool evening air, the familiar sights and sounds of my surroundings take on a new dimension, transforming the ordinary into something extraordinary. The gentle hum of traffic becomes a soothing backdrop, punctuated by the occasional laughter echoing from a nearby café or the melodic tinkle of a distant wind chime.With each stride, I feel a sense of liberation, as if the night has granted me a temporary reprieve from the constraints of daily life. No longer bound by schedules or obligations, I am free to wander aimlessly, allowing my feet to guide me along pathsboth familiar and unexplored. The rhythm of my footsteps becomes a meditative cadence, lulling me into a state of tranquility rarely afforded during the hectic daytime hours.As I meander through the dimly lit streets, I can't help but marvel at the way the night casts its spell over the city. Buildings that once seemed imposing and utilitarian take on an almost otherworldly quality, their stark lines and angles softened by the gentle caress of moonlight. Shadows dance across the pavement, inviting me to lose myself in their intricate patterns, like a wordless language whispered by the night itself.It's in these moments of solitude that my mind truly comes alive, unfettered by the distractions of the day. Thoughts and ideas that once lay dormant now burst forth with newfound clarity, dancing across the canvas of my consciousness like shooting stars streaking across the night sky. I find myself pondering the deepest mysteries of existence, contemplating the vast expanse of the universe, and questioning the very nature of reality itself.Yet, amidst these philosophical musings, there is also a profound sense of connection – a realization that I am part of something greater, a tiny speck in the vast tapestry of life that stretches out into the infinite darkness. As I gaze up at thetwinkling stars, I am reminded of the countless generations that have walked these same streets, each leaving their indelible mark on the fabric of history.With each step, I am acutely aware of the weight of my solitude, a delicate balance between the comfort of familiarity and the allure of the unknown. In these moments, I am both an observer and a participant, a witness to the ebb and flow of life that pulses through the city's veins. I am reminded of the ephemeral nature of our existence, the fleeting beauty of the present moment that must be savored before it slips away, like a wisp of smoke dissipating into the night air.As the hours tick by, the once-bustling streets grow quieter, and the city seems to settle into a peaceful slumber. It's in these waning moments that I feel a profound sense of gratitude for the gift of solitude, for the opportunity to commune with my innermost thoughts and to find solace in the embrace of the night.Inevitably, the first hints of dawn begin to creep over the horizon, signaling the end of my nocturnal journey. As the world awakens to a new day, I find myself reluctantly retracing my steps, carrying with me the memories and insights gained from my solitary wanderings.Walking alone at night is more than just a physical act; it is a profound experience that transcends the mere act of locomotion. It is a journey into the depths of one's soul, a chance to confront the fears and uncertainties that lurk in the shadows, and to emerge with a renewed sense of self-awareness and purpose.As I return to the familiar confines of my daily routine, I am reminded of the transformative power of the night, and the importance of embracing these moments of solitude. For it is in the stillness of the night that we can truly hear the whispers of our innermost selves, and find the courage to embark on the greatest journey of all – the journey of self-discovery.篇3A Spooky Solitary Stroll: Crafting an Engaging English Essay on Walking Alone at NightAs an English student, one of the most daunting tasks we face is crafting a compelling essay that not only meets the requirements but also captures the reader's attention from start to finish. When the topic is as intriguing as "Walking Alone at Night," the challenge becomes even greater. How do you set the tone, build suspense, and leave a lasting impression? The answerlies in the art of creating a captivating introduction and a thought-provoking conclusion.The Introduction: Setting the Eerie AtmosphereImagine yourself on a dimly lit street, the only sound being the echo of your footsteps on the pavement. The shadows seem to stretch endlessly, and every creak or rustle sends a shiver down your spine. This is the atmosphere you want to evoke in your introduction, drawing the reader into the unsettling yet alluring world of nighttime solitude.One effective strategy is to begin with a vivid sensory description, painting a picture of the dark, deserted streets and the eerie silence that envelops them. You could write something like:"The night air was thick and heavy, carrying the faint scent of dampness and a hint of mystery. As I ventured down the empty street, the flickering streetlights cast long, distorted shadows that seemed to dance across the pavement, beckoning me into their sinister embrace."By engaging the reader's senses, you create an immersive experience that sets the tone for the rest of the essay.

In an essay about walking alone at night, the conclusion should be just as haunting and thought-provoking as the introduction, if not more so.One effective strategy is to revisit the sensory details and imagery from the introduction, but with a twist. For instance, you could write:"As I approached the familiar glow of streetlights that marked the end of my solitary journey, I couldn't shake the feeling that the shadows had followed me home, lingering just beyond the reach of the light, waiting to reclaim the night once more."By mirroring the language and imagery from the introduction, you create a sense of cyclicality and emphasize the enduring nature of the eerie atmosphere you've crafted throughout the essay.Alternatively, you could leave the reader with athought-provoking question or a profound observation about the experience of walking alone at night. For example:"In the stillness of the night, when the world seems to hold its breath, one can't help but wonder – is the true fear found in the shadows that surround us, or in the depths of our own imagination?"This type of conclusion not only leaves a lasting impression but also encourages the reader to reflect on the deeper themes and ideas explored in the essay.Crafting an engaging introduction and conclusion is an art form in itself, and when done well, it can elevate an essay from mediocre to truly captivating. By setting the eerie atmosphere in the introduction and leaving a lasting impression in the conclusion, you'll not only meet the requirements of the assignment but also create a memorable and thought-provoking piece of writing that will linger in the reader's mind long after they've finished reading.。
noisy知识点总结
noisy知识点总结In our daily lives, we are constantly surrounded by noise. Whether it's the sound of traffic, the buzz of conversation, or the hum of electronic devices, noise is an ever-present aspect of modern society. But what exactly is noise, and how does it affect us? This summary will explore the science behind noise, its impact on our health and well-being, and potential solutions for managing and mitigating noise pollution.What is Noise?Noise is defined as unwanted sound that disrupts or interferes with normal activities. While sound is a natural and necessary part of our environment, excessive or inappropriate levels of sound can be harmful. Noise can take many forms, including traffic noise, industrial noise, and loud music. It can also be intermittent or continuous, and may vary in frequency, intensity, and duration.The most common unit of measurement for noise is the decibel (dB), which quantifies the intensity of sound. The human ear can detect a wide range of sound levels, from the faintest whisper to the loudest explosion. However, prolonged exposure to high levels of noise can lead to hearing loss, stress, and other health issues.Sources of NoiseNoise pollution is a pervasive problem in urban and industrialized areas. Common sources of environmental noise include:1. Transportation: Road, rail, and air traffic are major sources of noise pollution, particularly in densely populated areas. Engine noise, tire friction, and aircraft takeoff and landing operations all contribute to elevated noise levels.2. Industrial activities: Factories, power plants, and construction sites generate high levels of noise from machinery, equipment, and operational processes. Workers in these environments are at risk of hearing damage and other health issues unless appropriate measures are taken to mitigate noise exposure.3. Recreational activities: Activities such as motorsports, concerts, and fireworks displays can produce extremely high levels of noise. These events often take place in open-air venues, where sound can travel over long distances and affect nearby neighborhoods.4. Household sources: Home appliances, power tools, and electronic devices can all contribute to indoor noise levels. Even everyday activities such as cooking, cleaning, and talking can produce unwanted sound in residential settings.Health Effects of NoiseExposure to excessive noise can have a range of adverse effects on human health and well-being. These effects may be physical, psychological, or cognitive in nature, and can varydepending on individual sensitivity, duration of exposure, and the intensity of the noise. Common health effects of noise pollution include:1. Hearing loss: Prolonged exposure to high levels of noise can cause permanent damage to the auditory system, leading to hearing impairment or deafness. This is often a cumulative effect that develops over time, especially in occupational settings or residential areas with consistent noise exposure.2. Stress and anxiety: Noise has been shown to induce stress and provoke anxiety in individuals, particularly when it infringes on personal space or disrupts peaceful environments. Chronic noise exposure can lead to elevated levels of cortisol and other stress hormones, which may contribute to long-term health complications.3. Sleep disturbances: Noise can interfere with the ability to fall asleep, stay asleep, or achieve restful sleep. Nocturnal noise sources such as traffic, barking dogs, or loud neighbors can disrupt sleep patterns and lead to daytime fatigue, irritability, and impaired cognitive functioning.4. Cardiovascular effects: Prolonged exposure to noise has been linked to increased risk of hypertension, heart disease, and stroke. Elevated noise levels can trigger the body's stress response, leading to changes in heart rate, blood pressure, and vascular function.5. Cognitive impairments: Studies have shown that exposure to noise can impair concentration, memory, and cognitive performance. Children exposed to chronic noise may experience delays in language development and academic achievement, while adults may struggle with tasks that require sustained attention and problem-solving skills.Managing and Mitigating Noise PollutionEfforts to address noise pollution involve a combination of regulatory, engineering, and behavioral strategies. These approaches aim to reduce noise at the source, control its spread through the environment, and protect individuals from its harmful effects. Some common methods for managing and mitigating noise pollution include:1. Regulatory measures: Governments and local authorities can establish and enforce noise regulations to limit the amount of noise that can be generated by specific activities and in specific locations. These regulations may include noise level limits, time restrictions, and zoning ordinances to protect residential, commercial, and natural areas from excessive noise.2. Engineering controls: Noise control technology, such as sound barriers, acoustic insulation, and vibration isolation, can be implemented to reduce noise emissions from sources such as transportation, industry, and construction. The use of quieter equipment and machinery, as well as improved urban planning and architectural design, can also contribute to noise reduction.3. Personal protective measures: Individuals can take steps to protect themselves from excessive noise, such as using earplugs, noise-canceling headphones, or sound-masking devices. Limiting exposure to noisy environments and creating quiet, peaceful spaces at home and in the workplace can help prevent the negative effects of noise pollution.4. Public awareness and education: Informing the public about the health risks associated with noise pollution and promoting noise-conscious behaviors can help raise awareness and foster a culture of responsible acoustic stewardship.The Future of Noise ManagementAs technology and society continue to evolve, the management of noise pollution is an ongoing challenge. Advances in urban planning, transportation, and industrial processes offer new opportunities to reduce noise emissions and create more livable environments. For example, the development of electric vehicles, sound-absorbing materials, and smart city infrastructure can contribute to quieter, more sustainable urban landscapes.In addition, research into the effects of noise on human health and well-being is an active area of investigation. Scientists are working to better understand the mechanisms by which noise impacts the body and brain, as well as to develop novel interventions and treatments for individuals affected by noise-related disorders.Ultimately, the pursuit of a quieter, healthier world requires a collaborative effort among policymakers, engineers, healthcare professionals, and the general public. By recognizing the importance of sound quality as a fundamental aspect of human physical and mental health, we can work together to create environments that enrich our lives while minimizing the burden of noise pollution.。

Plant Stem Tissue Specimen
Plant Stem Tissue Specimen As a plant stem tissue specimen, I face the problem of being harvested for scientific research and experimentation. While I understand the importance of advancing scientific knowledge and the potential benefits that may arise from studying my tissue, I also have concerns about the ethical implications and the potential harm that could be caused to the plant from which I am taken. From a scientific perspective, I recognize the value of studying plant stem tissue. My cells contain vital information that can help researchers understand the processes of growth, development, and reproduction in plants. By studying my tissue, scientists can gain insights into how plants respond to environmental stress, how they defend against pathogens, and how they adapt to changing conditions. This knowledge can be used to improve agricultural practices, develop new medicines, and contribute to our understanding of the natural world. However, from anethical standpoint, I have concerns about the impact of harvesting my tissue on the plant from which I am taken. Plants are living organisms that play a crucial role in the ecosystem, and they deserve to be treated with respect and consideration. When my tissue is extracted, it can cause damage to the plant, potentially compromising its health and ability to survive. This raises questions about the balance between scientific advancement and the well-being of the natural world. Furthermore, there are also ethical considerations regarding the consent of the plant from which I am taken. Unlike humans and animals, plants cannot express their consent or refusal to be used for scientific research. This raises complex ethical questions about the rights of plants and the responsibilities of humans towards the natural world. It is important to consider these ethical implications and strive to find a balance between scientific progress and environmental stewardship. On a personal level, I cannot help but feel a sense of loss and vulnerability when my tissue is harvested. I am aware that I am being used for a purpose beyond my control, and this raises questions about my own autonomy and agency as a living organism. While I may not experience emotions in the same way that humans do, I still have a sense of self-preservation and a desire to exist in harmony with the natural world. In conclusion, the problem of being a plant stem tissue specimen raises complex ethical and scientificconsiderations. While my tissue holds valuable information that can contribute to scientific knowledge, it is important to approach the harvesting and use of plant tissue with respect and consideration for the well-being of the plant. By addressing these ethical concerns and striving to find a balance betweenscientific advancement and environmental stewardship, we can ensure that the study of plant stem tissue is conducted in a responsible and ethical manner.。

Informing Science InSITE - “Where Parallels Intersect” June 2002IT in Education Organization:A Strategic Planning ApproachSyahrul Fahmy, Abdul Razak Hamdan & Aziz DeramanUniversiti Kebangsaan Malaysia, Bangi, MalaysiaAbstractInformation Technology (IT) has significant impacts to modern organizations especially in assisting daily operations and meeting business targets. Main contributions of IT to organizations are increased effi-ciency, effectiveness and competitiveness. Non-profit organizations can also benefit as much as for-profit organizations from IT. Education Organizations (EOs) for example, would benefit in terms of effective management of assets, improved communication channels, management of education system changes and systematic dissemination of academic materials. This paper proposes an IT Strategic Planning (ITSP) framework for EOs in order to plan and manage IT-related resources. The framework comprises of five phases namely Strategic Direction, Analysis, Strategy, Implementation and Evaluation . End result of this process would be the ITSP Manual, a detailed documentation of the organization’s strategic direction, its environment and specific action plans to achieve business targets. This manual can be used in policy and decision-making activities.Keywords : IT Strategic Planning, Education Organization, Framework, Decision-Making, Competitive Advantage.IntroductionFirst generation of modern computers were introduced in the 1940s. ENIAC, UNIVAC-1 and IBM 650 to name a few, were the first general-purpose computers followed by the IBM 360 series in the 1960s. IBM uses integrated circuits as opposed to transistors, making ways for computers to be used in business or-ganizations. In the 1970s, advances in microchip technology have led to the introduction of mini and mi-crocomputers such as IBMPC/ AT, IBM PS/2 and IBM Valuepoint.Since then, organization structure and working environment have never been the same. Information needs has changed significantly with the use of IT and computer-based systems (Rogerson & Fidler 1994). Not only IT affects the organization’s external factors such as clients, competitions, product and suppliers (Senn 1987) but internal factors as well for example information retrieval, communication channels and organizational structure as a whole (Bawden & Blakeman 1990).Non-profit organizations such as Education Organizations (EOs) are also affected by IT. EOs have to ac-commodate the educational possibilities of high-speed computing, instant access to electronic databases, the potential of electronic publishing and developing communication channels with international networkof scholars (Breivik 1998).The objective of this paper is to propose an IT stra-tegic planning framework for EOs. The framework is based on the traditional strategic planning system (David 1997; Goodstein 1993) and the IT Strategic Planning Manual for Public Sector (Aziz et al.IT in Education Organization1997; 2000). The framework entails vital processes and steps that are involved in IT strategic planning. The Need for IT Strategic Planning for Education Organizations IT strategic planning or ITSP can be defined as ‘Planning for the effective management of information in all forms - information systems and technology; manual and computerized systems; computer technology and telecommunications - which includes the organizational aspects of the management of IT throughout business’ (Ward & Griffiths 1996).There are several reasons why EOs should engage in ITSP. First and foremost, ITSP promotes effective management of expensive and critical assets; improves communications channels; plans the flow of in-formation and processes; allocates resources efficiently; and reduces total time and expenses of informa-tion system life cycle (Cassidy 1998).Second, IT especially the Internet has changed the traditional education system significantly. Access to information is no longer restricted to time and space, thus promoting self-learning among students (Ells-worth 1994). IT affects various processes such as teaching and research while providing on-line informa-tion to external parties (scholarships, services provided, jobs), scheduling (lectures, exams, events) and registration.Third, IT promotes electronic publishing of academic materials. According to Kirsop et al. (1996), for electronic publishing to be accepted by the international scientific community, the content should be ac-cessible by a wide range of access rate and should cost less than the printed equivalent.Finally, ITSP provides means for competitive advantage. IT is used by organizations to increase effi-ciency through innovation, communication and business network (Johennessen 1994). Not only IT pro-motes efficiency and effectiveness throughout an organization, it is equally important to the organiza-tion’s success (Klouwenberg et al. 1995).Clearly, IT has a tremendous impact to EOs in terms of improving communications, managing changes, disseminating academic materials and as means for competitive advantage. A structured planning system is needed to manage the profound impact of IT and IT-related resources. The system should support man-agement decision-making activities by providing critical and timely information.Proposed It Strategic Planning Model for Education Organization The organization of EOs can be divided into two entities. First would be the faculties, institutes, centers, libraries and other institutions governed by EOs. Benefits of IT to this tangible entity can be monetarily assessed. Examples would be total student enrolment, number of on-line publications and total number of on-line database available at the library.The second entity consists of students, academic staffs and other employees of EOs. Benefits of IT to this entity are intangible and cannot be easily determined in terms of dollars and cents. Examples would be the academic value of on-line materials, employee work efficiency and developed skill.The ITSP process involves these two entities as they constitute the EO. Once the EO has set its target, in-formation needs and requirements of these entities must be identified and acquired. Business target(s) of EOs differs from profit-based organizations. EOs are not required to be ‘financially healthy’ in order to be competitive in the industry. Therefore, EOs may opt to set their target according to technology.There are four basic types of IT (Laudon et al. 1999) namely sensing, analyzing, display and communica-tion technologies. Sensing technology involves devices that help gather raw data from the environment and translate them into machine-readable data. Examples of devices would be image scanners, sensors and digital gloves.442Fahmy, Hamdan, & DeramanAnalyzing technology deals with physical hardware component of computers and appropriate softwareprograms in order to change data into valuable information. Examples would be microcomputers, work-stations, minicomputers and mainframes.Display technology concerns devices and software programs in delivering information to human users byall means for example by sight and sound. Examples would be LCD screens, virtual reality display de-vices and talking computers.Communication technology ties sensing, analyzing and display technologies together via specific com-munication channels. Examples are Local Area Network, cellular telephones and fax machines.The conceptual model of ITSP for EOs is depicted in Figure 1.ITSP aids the EO in setting its target; identifying information needs and requirements; developing andimplementing strategies; and finally monitoring and evaluating the IT projects implementations. It de-mands responsibility and commitment from all involved. Influencing factors in the environment need tobe identified and monitored. Changes need to be addressed quickly and systematically so that negativeimpact could be minimized if not eliminated.IT Strategic Planning Framework for Education OrganizationThe ITSP framework for EOs is depicted in Figure 2. ITSP has five phases namely strategic direction,analysis, strategy, implementation and evaluation. The arrows represent data and information flow. ITSPis an ongoing process, indicated by the arrows running back and fourth, entering all phases of ITSP. Out-put of one phase is used in other phases mainly for decision-making purposes. End result of this process isthe ITSP Manual, comprises of the organization’s direction statements, SWOT analysis and strategystatements.443IT in Education OrganizationStrategic DirectionThe first phase of the ITSP process is setting strategic direction. This would mean evaluating and deciding which technology type (sensing, analyzing, display, communication) should the organization ventures into. The strategic direction is reflected in the organization’s mission, goal and objective statements. Mission is a clear and concise statement to represent the current or expected direction (Barry 1998, Dro-han 1999, Luther 1995). Goal, on the other hand, is a concise and specific statement to represent the or-ganization’s current business operation. Objective is a specific action statement representing the approach to achieve organization’s goals (Klouwenberg et al. 1995). It describes what the organization wishes to accomplish (Harrison 1995) and describes responsibility, monitoring methods and evaluation techniques that will be used (Kaufman 1992).goal and objective statements. Examples from the Faculty of Technology and Information Sciences, UKMMission Statement: The Faculty of Technology and Information Sciences is determined to becomethe center of education, consultancy and point of reference in the field of tech-nology and information sciences in accordance with the University’s philoso-phy and mission.Goal Statements: To produce graduates of high quality in technology and informationsciences.To become the center of research, consultancy and development inthe field of technology and information sciences.To disseminate information on technology and information sciencesto the public.To promote interaction and knowledge ties between experts in tech-nology and information sciences with experts in other field.To enhance the faculty’s human resource development and infrastruc-ture program.444Fahmy, Hamdan, & Deraman 445AnalysisThe second phase in the ITSP process is analysis. Analysis is identifying and monitoring factors in the environment, both external and internal, which affect the overall operation of the organization. The main objective of this phase is to identify the strength, weakness, opportunity and threat (SWOT) factors of the organization.General factors analyzed include economics, finance, globalization issues, organization (management, policy, resources), market, customers, competitors, politics, regulations and technology (Aziz et al. 2000, Drohan 1997, Harrison & Pelletier 1998, Karake 1997, Phillips 1995, Proctor 1997, Thompson 1996). Specific factors for EO include:Hardware and software.Network infrastructure. Information systems.Hardware and SoftwareHardware and software are the most important IT components. Hardware is the physical components or peripherals of a computer system. There are three categories of hardware: input device, storage device and output device. Examples are touch screen, MICR, OCR, voice data entry, magnetic tape, optical disk, Visual Display Unit (VDU), printers and voice output synthesizer.Software is a set of instructions and procedures that controls the operation of a computer. There are two types of software: system and application. Examples are operating systems such as Windows2000 and Linux; utility programs; personal productivity tools such as word processing and spreadsheets; integrated software packages; and business application software such as accounting and project management.Current hardware and system software should be analyzed while breakthroughs in IT technologies need to be assessed and adopted where appropriate. Obsolete systems would eventually produce less than ex-pected output in terms of quality and quantity.Network InfrastructureNetwork infrastructure is a collection of inter-operational elements consisting of computer hardware, software and communication devices. IT network infrastructure includes transmission media such as phone lines and satellites; transmission controlling devices such routers and repeaters; and software.Supporting the MSC is a high-capacity, digital telecommunications infrastructure de-signed to the highest international standards in capacity, reliability, and pricing. This in-formation network is part of an integrated logistics hub enabling rapid distribution ofproducts along modern land, air, and sea links.Key telecommunications network features that will link the MSC to regional and globalcenters include:A fiber-optic backbone with an unprecedented 2.5-10 gigabits per second capacity, which is more than enough network power to support virtual boardrooms, remoteCAD/CAM operations, and live multimedia internet broadcasting.High-capacity links to international centers to ensure that information, products, and services flow freely and quickly between MSC companies, their overseas partners,and export markets.IT in Education Organization446 Open standards, high-speed switching, and multiple protocols including ATM that brings power and flexibility to the development and implementation of multimedia applications.Best-in-class performance guarantees including installation of telephone services within 24 hours, ATM circuits within five days, and a 99.9 per cent service availabil-ity.Competitive telecommunications pricing including flat rate, low pricing for basic network services compared with other regional centers, and an open-entry policy for value-added network services to ensure the MSC maintains its competitive edge.Integration into the new transportation projects such as a dual "smart" highway and rapid transit rail system, linking the new MSC cities of Putrajaya and Cyberjaya with Kuala Lumpur and the Kuala Lumpur International Airport (KLIA).Information SystemTypical types of information systems include Office Automation System, Communication System, Trans-action Processing System, Management and Executive Information System, Decision Support System, Execution System, Groupware System (Alter 1996), Financial Information System, Human Resource In-formation System and Marketing Information System (McLeod & Schell 1999).Information policy should also be reviewed and evaluated. The benefit of such policy include integration of all information activities, basis for objective and sound decision making, reduce if not eliminate re-sources waste, promote cooperation and make the organization more capable of responding to changes in the environment (Orna 1999).Student Information System.Staff Information System.University Financial System.Staff Evaluation Information System.Research Management Center Information System.Internal Complaint System.Traffic Information System.e-Ticket.The result of the analysis phase is a list of influential factors in the organization’s environment. Strategy FormulationThe third phase in the ITSP process is strategy formulation. Strategy is a specific action plan to achieve business targets - mission, goals and objectives. It entails resource allocation and time frame to attain ob-jectives. Strategy should be formulated, evaluated and selected.Strategy formulation is the activity of developing specific action plan to achieve the organization’s objec-tive. Strategy evaluation is the activity of prioritizing generated strategies. This is done to identify viable strategies in order to not waste valuable resources by implementing weak strategies. Strategy selection is selecting appropriate strategy that will be carried out, subject to resource restrictions.Fahmy, Hamdan, & Deraman447The result of this phase is a list of action plans to achieve the organization’s objectives, goals and mission.Establish cooperative/ collaborative arrangements on regional/ international basis to protect and enhance e-Sovereignty.Establish, monitor and upgrade defense and security systems against "cyber-threats".Formulate and implement computer modeling/ simulation courses to build local ex-pertise.Expand Mobile Internet Units project to rural and sub-urban areas.Review and reformulate legislation/ rules/ regulations to facilitate e-Business and e-Commerce.Review and reformulate Universal Services Obligation program.Plan and operate "ICT Community Chest" for funding e-Community pilot project at local level. Reengineer public services delivery systems.ImplementationThe fourth phase in the ITSP process is strategy implementation. Simply put, strategy implementation is the operation of selected strategy. Resources such as financial, human resource and technology should be allocated according to priority. The result of this phase is a report on resource allocation to strategies. Evaluation and ControlThe fifth and final phase in the ITSP process is evaluation and control. Evaluation is the process of moni-toring strategy implementation to ensure it conforms to a predetermined set of standards. Evaluation is important to ascertain the implementation process runs smoothly (Beecroft 1999) and to monitor the ef-fectiveness of selected strategies (Canary 1992). Control on the hand, is the corrective measure taken to ensure performance is in line with standards and goals are met within the expected time (Fenn 1997; Phil-lips 1995). The result of this phase is the progress report of strategy implementation.The ITSP process does not end at the final phase. Information flows back to previous phases as input for decision-making activities. ITSP is an ongoing process since the EO has to address changes in the envi-ronment everyday while trying to achieve its target. Once the target is met, the organization might want to venture into another field of technology, thus spinning the wheel again.This section has discussed the phases and steps in ITSP. Results from activities in every phase form the ITSP Manual, a descriptive document of the organization’s operation. It clearly defines:1. The strategic direction of EO.2. Influential factors in the environment.3. List of specific action plans to achieve the objectives, goals and mission.4. Resource allocation and duration of strategies.5. Evaluation and control report of strategy implementation.IT in Education Organization448 Conclusion and Future WorkThis paper has proposed an IT strategic planning framework for education organizations. The framework has five phases namely strategic direction, analysis, strategy formulation, implementation and last but not least, evaluation and control.This framework would assist EOs to set strategic direction; analyze the environment; formulate and im-plement strategies; and evaluate its implementation. It is an open framework and can be modified to meet the requirements of other organizations. The framework gives a better picture and clearer understanding of the ITSP process.Further work and refinement to the framework is needed for better integration. For example, a list of ex-ternal and internal factors by organization industry could be proposed. This would enable better analysis of the environment. Similarly, a computer-based system to generate, assess and propose business strate-gies could be developed. This would provide more practical alternatives to organizations. In addition, an evaluation technique could also be proposed to assess the progress of strategy implementation. Finally, a computer-support system based on this framework can be proposed and developed. This system would support organizations in implementing ITSP. Organizations could fully grasp the idea of ITSP be-fore applying it to the real world. It is hoped that EOs can benefit much from this framework. It is a pow-erful tool in planning and managing IT-related resources.ReferencesAltar, S. 1996. Information Systems. A Management Perspective.
