When chemicals come together, they form a reaction. A chemical reaction is when one or more substances change into one or more new substances. The properties of the new substances are different from those of the original substances. You can tell a reaction has happened when you see these signs: a precipitate has formed, gas has formed, color has changed, or energy has been given off (blue book). If substances with new properties have formed, you know a chemical reaction has occurred. The substances that you start off with are called the reactants. The substances you get after a reaction has occurred are called the products. There are different types of chemical reactions. Exothermic reactions are a type of chemical reaction where energy is released and absorbed by nearby matter. Endothermic reactions are a type of reaction where energy is absorbed from from its surroundings (blue book). Chemical reactions happen at different rates. There are many factors that affect the speed of ch emical reactions. To make a reaction go faster you can increase the temperature, increase the concentr...

Analysis of Urban Composition using Space Syntax and Computer Techniques

A esteemed axiom from Winston Churchill goes that people shape edifices, and so edifices transform people. The affects from edifices, or more specifically, from the built environment to people is widely-belive in the thought of architectural and urban forms. It has led to some phantasies that trying to reform society by bettering design, such as the Claude-Nicholas Ledoux’s thought of â€Å"cites ideales† in 18Thursdaycentury and the thought of â€Å"reforming the environment alternatively of reforming the people. Peoples could alter themselves if the environment bend to be correct† by Buckminster Fuller in the sixtiess. The overtures to polish the interior relationship between built environment and societal life are truly uncommon apart from above. Under this circumstance, infinite sentence structure, a theory started twenty old ages ago which seting forward by Hillier and Hanson ( 1984 ) , being developed at the Laboratory of University College London and globally distribute over the old ages. Space sentence structure is to analyze the urban composing by utilizing computing machine techniques. In the words of Hillier et Al, infinite sentence structure is a group of techniques which contains the comprehensive cognition of some facets in edifices and colonies, such as quantitative analysis, representation and spacial constellation account. As a broadly definition of constellation, on one manus, it should see one tierce of the relation between two infinites at least, on the other manus, it should see complex dealingss among all infinites at most. Hence, spacial constellation is far more than merely a simple thought of spacial relation and demand to mention non merely a brace of related infinites ( 1987, p.363 ) . Harmonizing to Hillier ( 1984 ) , the 1 who made a breakthrough beyond others, in that infinite sentence structure had by now developed a precise method to depict topological dealingss, locally and globally at one time, in one graph, for edifice and colonies, as a social-spatial issue, with a witting theory about a deep construction in societal infinite in the built environment, in the original signifier of infinite sentence structure, it chiefly emphasized urban forms of the motion of prosaic. It was subsequently generalized to a figure of other countries, such as urban conveyance mold, calculating the grade of air pollution, measuring different vicinities burglaries occurred, and gauging the possibility of development of retail around the streets. In the work of â€Å"Space sentence structure: a different urban perspective† ( 1984 ) , Hillier mentioned three different facets. The intelligibility of infinite, the continuity of business and the predictability of infinite. He thought the spacial organisation of urban countries affects forms of motion and usage harmonizing to good defined rules. And he went on presenting how infinite sentence structure works. It is based on a dweller or a human organic structure in a local point, sing two points, visibleness and the permeableness and doing two waies, the longest axial line and the smallest bulging infinite to develop two maps, axial map and convex map, for urban colonies or edifices. In this manner of analysis, every point in the system has both a one- and two- dimensional facet which means every point has a local and planetary dimension. Now allow us concentrate on most widely used technique of infinite sentence structure in urban analysis, the axial map. Harmonizing to Hillier, in order to understand the â€Å"axial map† , the significance of â€Å"axial lines† and the word â€Å"integration† should be understand clearly. â€Å"Axial line† is basic elements of infinite sentence structure analysis, which is from unconditioned two human inherent aptitudes, visibleness and permeableness. ‘Axial line’ represents the lower limit and longest ocular line associating the different ‘convex space’ . The word â€Å"integration† is initial of import in infinite sentence structure. To explicate it, the construct of deepness should be known first. Take the five different plane types in Figure 1 ( from left to compensate 1-1-1, 1-1-2, 1-1-3, 1-1-4, 1-1-5 ) for illustration, each program consists of three indoor infinites and an out-of-door infinite O. The Justified Graph , which show the relation between out-of-door infinite O and the remainder of infinites, is shown blew each program. The syntactic characteristics of infinites of five different program could be discerned from the Justified Graph. Comparing with F1-1-5 ( F= figure ) , F1-1-1 is a deep sentence structure. Therefore, F1-1-5 is a shallow sentence structure. However, F1-1-1 and F1-1-5 are deep tree sentence structure when comparing with F1-1-2 and 1-1-3. And F1-1-2 and F1-1-3 are two different deep ring sentence structure. Besides, F1-1-4 is a sentence structure between shallow tree sentence structure and shallow ring sentence structure. From the Justified Graph, convenient grade of different convex infinite could be easy shown. In F1-1-2, bulging infinite b2 locates on a deeper and less convenient topographic point comparing with a2 and c2. Although b4 locates on a shallow place, the convenient degree is inferior to infinite O. Because it is two justified stairss off from c4. However, c4 is the most inconvenient topographic point of the system, which is two justified stairss to a4 and b4. It should be noticed that the â€Å"deep† , â€Å"shallow† and â€Å"step† being discussed donnot stand for the existent distance. It is a construct of morphological. â€Å"Deep† and â€Å"shallow† merely show the degree of artworks and â€Å"step† means the figure of infinites from one convex infinite to another in the artworks. The value of integrating of a line linked to its deepness to other lines in one system. To be more specific, the integrating value in infinite sentence structure means how good of the system integrated, how good the elements within the system connect with each other. The most incorporate systems are those with shallowest lines on norm, and the most detached are those with deepest lines ( Hillier et al, 1993, page 35 ) . Integration is the chief portion of the analysis of axial map. The motion of people strongly depend on the integrating value of each line. Integration values play a important function in understanding the map of urban systems in line maps since it result in that the Numberss of motion which pass down each line has a high grade of influence by its integrating value. From some of the point of view, infinite sentence structure is to widen the construct of web analysis to architecture design and urban planning. Its prognosis of motion is controversial. However, the map of infinite sentence structure can non be negated. To be more thorough, I read the book of â€Å"Space is a machine† , anther one written by Bill Hillier. In this subdivision some reappraisals of this book will be illustrated. 1. The position of â€Å"configuration† In the debut at the beginning, Bill Hillier stated that the most critical consequence in these surveies is the construct of â€Å"configuration† bit by bit enter into the centre of the phase. In short, the â€Å"configuration† is intended as a set of relationships. Each of them depends on all others’ association with it. New techniques of spacial analysis have been developed from these, which brings the spacial logic of architecture and urban to visible radiation. What is more, it besides quantifies a truth of the cardinal point being â€Å"how to form things together. Similar with the word â€Å"pattern† , constellation stress the overall construct of complex systems instead than partial. However, we do non utilize the word â€Å"pattern† due to the fact form means to follow regularity. The construct of â€Å"spatial configuration† means the unity of a relationship with any of the relationship depends on the relationships of all other relevant. Here showing a formal but simple definition: for two infinites, if we define the spacial relationship of any sort of connexion between them, such as next or exchange, the relationship between them will alter depend on the manner of any one or both of these two infinites linking with the 3rd infinite. Wherein the constellation is present ( p.14 ) . In the book, Hillier aimed to suggest a new design method, which the constellation is the nucleus construct. It insists that architecture design or urban planning is a procedure with constellation, which means the local alteration promote the overall alteration. Even if merely rely on the cognition of constellation can back up the design. Hillier recalled the infinite sentence structure theory and methodological analysis of some of import new accomplishments in the preamble. These consequences make a more solid and effectual theoretical foundation for infinite sentence structure.Space as a thing in itselfSpace is an nonsubjective property of houses, which can be independently described as material things. However, in architecture, it is rare to depict infinite wholly independent, such as â€Å"enclosed space† is to depict the infinite trusting on the physical signifier instead than to specify infinite as a unrestrained signifier. Roger Scruton see the construct of infinite is a consequence of an chesty architect’s systematic mistake. In the position of Scuton, infinite is non a thing in itself, but simply the antonym of physical entities, that is, the staying of the houses. The infinite of the Fieldss and interior infinite within the church seem no difference except the ornament of the church. Hillier made an illation about the beginnings of Scruton: Descartes thought that the first property of material objects is their â€Å"extension† , which are the properties can be measured, such as length, tallness and breadth. All of these do non trust on worlds. And the 2nd property is, to some extent, dependant on the subjective feeling of worlds, such as â€Å"green† or â€Å"good† . Widening to the construct of infinite, taking the objects from the infinite it occupies, the extension still exist. And this is an property of infinite. Therefore, infinite can be summarized as an extension without object. So when we remove the object from the infinite it occupies, we do non believe that the extension of the infinite has besides been removed. In this position, infinite is matching to the physical properties being defined so it becomes a mensurable belongings of material objects. Hillier believes that one time look upon the infinite from this position, you can non understand how it works in the infinite of human events. From the position of civilization and society, infinite is non merely a impersonal model of societal and cultural concept, but to the full integrated into the societal and cultural signifiers. Human behaviour is non easy occur in the infinite, but has its ain spacial forms. In the subdivision of â€Å"space as configuration† , the relationship between infinite and society does non be on the degree of a individual infinite or the person ‘s activities, but in the constellation of human and infinite. From this subdivision, the layout of spacial relationships is converted into J-diagram ( Figure accommodation ) to make analysis ( p. 11 ) . The demand for an analytic theory of architectureArchitectural theory is to utilize the constructs, words and Numberss to depict the unexpressible intuition, seeking to uncover one or a few unexpressible regulations. Possibly we can state that architectural theory is seeking to make a â€Å"inexpressible technology† , which we can manage those unexpressible signifiers, figuration and spacial forms. At least in some facets, architectural theory describes and steer the design. So in the footings of design, we can state architectural theory is an effort to command edifice design. The architectural theory discussed more in standardized in the yesteryear. They are deficiency of analysis. This is because those unexpressible engineerings merely depict a certain type of figuration. P36 After tonss of treatment about construct of â€Å"rule† and â€Å"theory† , the first measure of seting frontward the theory is the standardization of construct. And so get down to construct our â€Å"inexpressible technology† . The method Hillier used is turning the existent infinite into abstract infinite, to acquire a clear apprehension of these features. Using abstract co-ordinate system replace the infinite with object. In this system, the axis represent the belongingss which can be ruled. P38 With this co-ordinate system, change overing the belongingss of object into coordinate infinite and turn uping the object by utilizing a series of points. So the regularity of the belongings was revealed. This is a basic recording method, which can enter the similarities, differences and relationship between objects in an nonsubjective and independent manner. However, it should be noticed that what we have seen is non the theory. It is the procedure theoretical accounts produce those regulations. In the book, many of the constructs are divided into two different dimension of belongingss by â€Å"dichotomy† , such as the scientific and artistic of the architecture ( p.31 ) . For illustration, architecture is defined as a object and a activity at the same clip ( p.5 ) . And the most of import conceptual differentiation is the standardisation and analytic of architectural theory. Architectural theory by and large appears in normative manner. However, on a deeper degree, it is no less than scientific theories about analytic. Architectural theory is non and can non be a simple regulation. At least, it is a composite of analytic and normative. If the analysis of the theory is incorrect, so the design will non be successful. Architectural theory Tells us how the universe should be like, but we foremost have to cognize what sort of universe it is. ( p.29 ) Why architectural theory should utilize in this alone signifier? The reply lies in the kernel of the work of designers. To be more specific, it is the design. The kernel of design is an activity. It raises all sorts of issues, and architectural theoretician using theory in the signifier of analysis and normative and propose solutions to these jobs. The kernel of the procedure of design is create and anticipation. Theories are used to back up the procedure of create and the analysis of calculating procedure. R. A.

During the first day of our staying

Once upon a time my friends and I went on a hike. The company consisted only of the closest people. We chose a picturesque place with a lake and a forest nearby and intended to make our hike a perfect one. We dreamt about great weather and our dreams came true.During the first day of our staying there we took much photos, gathered berries and flowers. On the second day there we decided to change the place and to put up the tents somewhere else. So we moved closer to the lake, but chose a somewhat higher level, so that to reach the lake one should go down a path lying not far from our camping place. So the girls crawled into the tent while the guys occupied themselves with gathering twigs for a fire. I went to help them too.The girls began fooling around. As they later told us, suddenly they discovered that they moved a little bit with the tent. Then they moved more†¦ and more†¦ And then not just moved, but fell into the lake from a rather high and steep slope.They began scr eaming, crying for help, and shouting that much that we threw away the twigs and ran to them. Frightened and worried, we didn’t know what to do. Luckily enough, the trees held our tent and it stayed dry, so unlike the girls. Wet and scared, they got out of the lake and came back.That curious story didn’t end, though. When we wanted to fix the tent back, we noticed a nest of snakes covered with leaves on the ex-place of tent. I can hardly call us surprised in that situation. Thanking our destiny for helping us out, we moved to a more secure place. Carefully examined it, we put up there.I guess I can call that hike the most unforgettable thing in my life. I could never imagine that anything of the kind would happen to me†¦Ã‚  

Higher Education and the American Dream: Success and Its Discontents Essay

Is   College necessary? Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   It is true that a college may favor or not favor some victims. This means that it is not an assurance if you complete your college level you get a white collar job. This is not the case. However, it will depend on how one takes his/her time to associate with working class person and also to give voluntary service to the companies and government corporation. According to Baker it is very important for the child to attend basic education in the age of six years, he says that the child during this age is being prepared psychologically on how to move on to the next academic level. Additionally, Baker brings out another crucial sense why it is important to go to the college after graduating the high school. Baker says that colleges are preparing a student not only to get well-paying job but also, on how as a student one can business oriented person. Very important issue here is that a college graduate student can be compared with primary or hig h school student in terms of thinking capacity.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   College is not worth some time for some people. Meaning that in a society some people tend to have very little education but, their way of living is luxurious. However, this will depend on one’s fortune. Another factor that might make people look down to the college is family background(Charles chpt8). Some families are very rich such that they do not push their kids to go for further studies but, rather after completing their high school education they are given capital to start their own business or even they inherit some of their family business. So, college may not be very important to such people because the aim of going for higher education is only to have good living standards. Therefore, if one gets a good amount of dollars that can sustain him/her then there is no need to go to college.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the past century, education was not highly valued in many countries. This was because many people had inherited big wealth from their forefathers. Therefore, they tend to depend on those properties for their upkeep, unlike this 21st century where is only depends on how one struggles to be able to sustain himself. In the past century, technology had not improved like the this century thus people had limited resource in education, for instance, less developed countries(Lazerson chpt12). Hence, the aim of going to colleges was not there. However, going to college to further studies is a great idea in order to increase knowledge and be conversant with the current trend on technology that is not taught in primary and high school level. In conclusion, college education is very important to the graduates. It is observed that graduates are not enrolled to colleges in order to secure themselves or to go for well-paying job, but they do so in order to be civilized. They are also equipped with knowledge that helps them to run their own business. In fact, college education has a lot of benefits. Finally, it is wise to be a college graduate rather than having basic education (primary and high school). References Lazerson, Marvin.

Employment and its effects on high school and college students’ grade point averages Essay

Many students, parents, and educators have been seeking the so-called Holy Grail of learning for many decades. One question that has arisen out of this learning model is that of student employment? Many wonder if working a part-time job will affect a student’s grades, and if so, how much? The answer to this seemingly simply question, however, is more complex. A variety of factors must be considered when deciding if and to what extent a student’s grades are affected by his or her employment status. In recent years, the concept of the full-time student seems to be disappearing. From about age sixteen, an overwhelming majority of students, both high school and college, work while they attend school. This average is about 85% for most college students (Bradley, 2006). However, high costs everything from apparel to tuition drives these workers into their part-time jobs which are generally retail and service related businesses for an average of fifteen hours per week (Bradley, 2006). Generally, most studies do identify some differences in academic performance and attitude, but these differences are not as great as people once may have believed. Generally, studies find very few basic differences between working and non-working students, especially in college. However, the intensity of the job and the number of hours worked did seem to affect academic performance in many students at the high school level. Generally longer hours meant more stressors on the individual and had a negative affect on their grades, which translates into about a half of a grade point average(GPA) point lower than not working students or students who work only a few hours, perhaps on the weekends (Weller et al, 2003). Oettinger (1999) also found this to be true, and noted that minority students tended to be more affected by the GPA drop than white students. He noted his drop in GPA to be about . 20 points and to be most obvious in students working more than twenty hours per week. These studies corroborates a study done nearly twelve years earlier in which the researchers found, similarly, that students who put in longer hours at their jobs suffered lower grades, higher absenteeism, and less interest in school in general which was seen in negative behaviors while in school (Perils of Part-time Work for Teens, 1991). At the college level, these differences were less noticeable. Ironically, Bradley (2006) found that the grade point averages were highest for students who did not work AND for students who worked more than twenty hours per week. This seems to contradict the research done on high school students, suggesting that maturity and attitude may also play a part in the employment/grades debate. Research has also been conducted on academic attitude and perception as they relate to grades. In high school, students who worked longer hours did not seem to have much distress about their grades as a result of the employment: â€Å"Those who had jobs displayed no advantage over the others in self-reliance, self-esteem or attitude toward work† (Perils of Part-time Work for Teens, 1991). In addition, students who worked even seemed to report less school stress, possible because they had less interest in school, as mentioned above. Moreover, researchers explain this more blase attitude toward schools by the findings that students who worked were more likely to report avoiding difficult classing, cheating on exams, and copying homework from friends (Weller et al, 2003; Perils of Part-time Work for Teens†, 1991). This was not the case for university students. In college, students who worked perceived that their employment DID affect their grades even when the researchers found little or no interest in grades between non-workers and workers at the college level. Both working and non-working college students showed a high level of interest in their grades and expressed an overall desire to achieve a high level of academic performance. Students who did not work stated that did not do so in order to focus on their studies, and they believed that their studies benefited from this extra time. Again, though, the studies showed no difference in the GPAs of working and non-working college students (Bradley, 2006). Instead many researchers ponder how college students who work so many hours are able to keep similar GPAs to those that do not work. Bradley (2006) suggests that nonworking students may be spending similar time with other activities such as sports, extracurricular clubs, or even caring for dependents at home. He also proposes that the non-working students and the working students may be approaching homework and study in different ways. He notes that non-working students â€Å"may be most likely to adopt a ‘deep’ learning style, characterized by intrinsic interest in the subject content and a desire to maximize understanding of this content† and that working students â€Å"may be more likely to adopt an ‘achieving’ style aimed at maximizing grades through the effective use of space and time. † These learned differences could certainly account for the way different students juggle the demands of work. It is certainly helpful to note when employment can be an effect socialization tool aimed at building strong character and organizational skills and when it can be a definite academic detriment. Research shows that more differences exist for high school students than for college students, and that the majority of the college differences exist only in perception, not in actuality. This gives rise to the possibility of further research which could focus on the characteristics of working students who do keep their GPAs high.

The fail city---Philadelphia, PA Essay Example | Topics and Well Written Essays - 1750 words

The fail city---Philadelphia, PA - Essay Example It has an art and culinary mix that is reflective of its ethnic mix of Irish, Scottish, and German immigrants in the seventeenth century, then followed later mostly by immigrants from southern and eastern Europe such as Poles, Italians, Hungarians, etc. and followed again by another immigrant wave of African-Americans during a period called as their Great Migration in the early twentieth century. Before the European settlers and colonizers came to Pennsylvania, this state is the home of the Delaware native-American tribe as well as other Indian tribes like the Iroquois, Shawnee, Erie, and Susquehannock. Pennsylvania is one of the original thirteen states which declared independence from Great Britain. Although its state capital today is Harrisburg, it is Philadelphia which has a rich historic legacy in most important events of American history, like the Declaration of Independence (1776) and the signing of the Constitution (1787), as it was the preferred meeting place of the Founding Fathers. Philadelphia once surpassed Boston as a chief seaport in the mid-Atlantic seaboard. This paper examines the success factors of Philadelphia from an anthropological, economic, and political viewpoint during its heyday. Discussion Philadelphia had always been the center of most human activities since its early time as a European settlement. As such, its success can be viewed from an anthropological angle or perspective because it was, and still is today, a melting pot (or salad bowl) on the East Coast. The original settlers of Philadelphia were the Indians and a first wave of European colonizers was the Dutch, followed by the British, and then a bit later, by the Swedes. The resulting mix of various European settlers intermarried with the natives. This mixture of peoples produced a tolerant attitude towards other cultures and got the best aspects of each culture to make the present culture of Philadelphia today which is progressive, flexible, and open to new ideas. The peopl e of Philadelphia are composed mostly of white Europeans (almost 82%) who are non-Hispanic with the next big majority being either black Americans or African- Americans (non-Hispanic origin). Besides these two, there are also many ethnic groups in the city’s population such as Native Americans (descendants of the remnants of original tribes) and Asians such as Pakistanis, Chinese, Indians, Vietnamese, Koreans, and Cambodians. The composition of Philadelphia’s population is truly cosmopolitan hence it is similar to New York City in terms of ethnic diversity. The different groups learned to live with each other in peace due to close proximity and tolerance for their differences. Philadelphians have learned to accommodate, cooperate and collaborate in the racial politics of culture (Baker 130). Although anthropology has four main areas of concentration in terms of study (the sociocultural, biological-physical, archaeological, and lastly, linguistics anthropology) it is th e sociocultural aspects of Philadelphia’s anthropology which can best explain its success as a big, modern city. This is to examine the city in terms of its sociocultural features such as in social patterns, religious beliefs, and cultural practices, as defined (American Anthropological Association, para. 2) because it determines justice, balance of

Management and Organisation individual report Essay - 1

Management and Organisation individual report - Essay Example An institution at its base brings with the standards and behavior of its founders and these become the institution’s cultural features. As the organization grows through time these effects become entrenched into the organization’s property, framing central standards, defining assets needed and the organization’s characteristic persona that describes its intentions, priorities, and routines (Buchanan & Huczynski, 2009). Introduction The culture of an institution has its own inimitable organization culture. Frequently this culture has been advanced by the institution’s founder management. Thus, it may be transformed and affected by the behavior of groups and persons, in addition to external factors. Institutional culture is viewed by academics and practitioners in a similar way as being essential in how the institution achieves its goals and its productive business. Organizational productivity Mullins (1) implies is described in terms of institution’s capability to make sure goal achievement, fulfillments, resource acquisition, identity and devotion of its members, imitations to transformations and fulfillments of external shareholders. Organizations with purposeful interpersonal communication may accomplish a better share definition of the institution and therefore a better communication atmosphere (Dick & Ellis, 2005). 1.0. Organizational Culture Organizational culture is normally the best means to manage as a way of accomplishing success. It is also a significant element of productive organization creation and performance. This view of the significance of organizational culture seems to draw on institutional hypothesis and behavior from a spectrum of sciences including, psychology, sociology and anthropology. An organizational culture encompasses the atmosphere adjoining the institution, prevailing attitudes inside it, motivation, strength of feeling toward it and collective levels of goodwill. Thus, organizational culture an d organizational transformations are frequently entwined with one another. Further organizational culture grows continuously as institutional transformation take place along an intermediary curve. Transformation is normally being implicated specifically by the organization’s leaders to suit their own choices or transforming market processes and in doing so implicates the decisions making process. Culture in flexible and dynamic and can be affected by internal and external challenges including dysfunctional managerial behavior that will impact on the workers in fields such as poor job performance, job dissatisfaction, turnover and burnout (Handy 1993). An institutional behavior that can be identified in institutions, specifically those experiencing transformation is opposition by workers to transformations in the work atmosphere. Whether the institution is experiencing primary reconfiguration or is the process of transformation due to invariable inventiveness and development, workers may pull back and resist transformations, specifically if they do not comprehend the transformations. However the requirement for successful transformation including transformations to mission, vision, culture, communication and leadership all require be achieved, and failure to be accomplished in them all will amount to the entire transformation failing (Mullins, 2011). 1.1. Groups and their
